Description

TECHNICAL FIELD

Embodiments of the present application relate to the technical field of physiotherapy devices and specifically relate to a head of a physiotherapy device and a physiotherapy device.

STATE OF THE ART

Currently, physiotherapy devices are widely used in physiotherapy. A physical therapy device includes a physical therapy device body and a conductor. The conductor includes a connector and a wire. One end of the wire is connected to a connector and the other end is for connecting to an electrode pad to transmit an electrical signal transmitted through the physiotherapy device body to the electrode pad.

A Type-C connector is widely used because its structural symmetry means it can be used normally even when the plug orientation is reversed. If a Type-C connector is used directly as a connector of a conductor of a physiotherapy machine, accidentally inserting the plug of the conductor of the physiotherapy machine into a physiotherapy machine body that is not matched to the conductor could cause excessive current and come into contact with an electrode pad for physiotherapy the human body, so that excessive current could injure the human body as a result of incorrect plugging.

CONTENT OF THIS APPLICATION

In view of the above problem, embodiments of the application provide a conductor of a physiotherapy device and a physiotherapy device to prevent the plug from being inserted into a large current device whose Type-C socket is not improved, and thus avoid injury to the human body .

According to one aspect of the embodiments of the present application, a head of a physical therapy device is provided. The conductor includes a connector and a wire. A first end of the wire is electrically connected to the plug and a second end of the wire is used for electrical connection to an electrode plate. The plug includes a handle portion and a first plug portion; wherein a first end of the handle portion is connected to the wire and a second end of the handle portion is connected to the first plug portion; wherein the first plug-in section has the same external shape as a plug-in section of a Type-C plug. The second end of the handle section is further provided with a circumferential bulge section which surrounds the first plug-in section and has the same height as the first plug-in section, the bulge section being point-symmetrical with respect to a center line of the first plug-in section, between the bulge section and the first plug-in section a circumferential gap is formed, which is used to coordinate with a second plug-in section of a conductor socket on a physiotherapy device.

In the head of a physiotherapy device according to the exemplary embodiments of the application, the bulge section of the plug surrounds the first plug-in section and a circumferential gap is formed between the bulge section and the first plug-in section. The gap serves to match the second plug-in section of the conductor socket on the physiotherapy device, so that the plug can be plugged onto a physiotherapy device body that is matched to the plug of the conductor. The bulge section has the same height as the first mating section, so that the first mating section is restricted when inserted into a Type-C socket that is not matched to the bulge section and therefore the plug cannot be inserted into a device whose Type-C Socket is not improved, for example, a physiotherapy device body with too large current or a mains voltage device, can be inserted to avoid injury to the human body. Furthermore, the first plug-in section has the same external shape as a plug-in section of a Type-C plug, and the bulge section is point-symmetrical with respect to the center line of the first plug-in section. Therefore, the connector of the physiotherapy device conductor improved according to the embodiment of the application can be inserted in both normal and reverse orientation, providing good usability and improved user experience.

In an optional embodiment, the bulge portion is made of an insulating material. By making the bulge portion of an insulating material, the probability that the bulge portion is energized can be reduced, thereby reducing the risk of electric shock to the human body.

In an optional embodiment, the handle portion and the bulge portion are injection molded in one piece. The handle section and the bulge section are injection molded in one piece, ensuring structural stability between the bulge section and the handle section is increased. This makes it possible to prevent the bulge section from being secured against incorrect insertion due to deformation and thus the plug being able to be plugged into another physiotherapy device or a device with mains voltage, or from the fact that due to deformation of the bulge section the plug is not in a position that is matched to the plug The conductor socket of the physiotherapy device can be plugged in.

In an optional embodiment, the length of the bulge portion is less than the length of the handle portion and the width of the bulge portion is less than the width of the handle portion. The length and width of the bulge portion are smaller than the length and width of the handle portion, respectively, thereby reducing the material consumption of the bulge portion and saving costs. Furthermore, the dimension of the handle portion is larger than that of the bulge portion, making it easier for users to grip and improving the user experience.

In an optional exemplary embodiment, the distance from the inner wall of the bulge section to the outer wall of the first plug-in section is 0.7 to 1.1 mm. Because the distance from the inner wall of the bulge section to the outer wall of the first plug-in section is in this range, a suitable size of the gap between the bulge section and the first plug-in section is achieved, thereby facilitating insertion and unplugging of the plug.

In an optional exemplary embodiment, the distance from the inner wall of the bulge section to the outer wall of the first plug-in section is 0.85 to 0.95 mm. Because the distance from the inner wall of the bulge section to the outer wall of the first plug-in section is in this range, inserting and unplugging the plug is made easier.

In an optional embodiment, the wall thickness of the bulge section is 0.9 to 1.4 mm. Because the wall thickness of the bulge portion is in this range, the bulge portion is not susceptible to deformation even under the influence of an external force or when the plug is repeatedly plugged in and unplugged.

In an optional embodiment, the wall thickness of the bulge section is 1.1 to 1.3 mm. The thickness of the bulge portion in this area is appropriate.

By not making the bulge section excessively thick, material can be saved. Also, by not making the bulge portion excessively thin, the bulge portion is not susceptible to deformation.

In an optional exemplary embodiment, it is provided that a first layer of contact pins and a second layer of contact pins are arranged on the first plug-in section, wherein both the number of contact pins of the first layer of contact pins and the number of contact pins of the second layer of contact pins are N and N> 4, where N is an integer, wherein the first layer of contact pins and the second layer of contact pins are arranged point-symmetrically with respect to the center point of the center line of the first plug-in section and contact pins of the first arranged point-symmetrically with respect to the center point of the center line of the first plug-in section layer of contact pins and the second layer of contact pins each form a pair of contact pins; wherein the number of wires is also N, with a first end of each of the wires being electrically connected to one of the pairs of contact pins and a second end of each of the wires being electrically connected to a pin, each of the pins being connected to one of the pairs of contact pins via the respective wire is electrically connected to receive a signal transmitted through the conductor socket. By providing the wire in a number of N, the first end of the single wire is electrically connected to one of the contact pin pairs of the two layers of contact pins of the first plug section and the second end of each of the wires is electrically connected to a plug pin and each of the plug pins above the respective wire is electrically connected to one of the pairs of contact pins, the pins can receive various signals transmitted by the physiotherapy device body via the connector and the wires to meet user requirements for various physiotherapy effects. Since a plug can be connected to four or more wires, the number of the plug and the number of the conductor socket on the physiotherapy device body can be reduced, thus saving costs.

According to another aspect of the embodiments of the application, an embodiment of the application further provides a physiotherapy device comprising a physiotherapy device body and the conductor according to one of the above embodiments, wherein a conductor socket is provided on the physiotherapy device body for electrical connection to the plug.

Currently, physiotherapy devices are widely used in physiotherapy. If a Type-C connector is used directly as a connector of a conductor of a physiotherapy machine, accidentally inserting the plug of the conductor of the physiotherapy machine into a physiotherapy machine body that is not matched to the conductor could cause excessive current and come into contact with an electrode pad for physiotherapy the human body, so that excessive current could injure the human body as a result of incorrect plugging.

In order to solve the above problem, the inventor found that insertion of the plug into a standard Type-C socket can be prevented by providing a bulge portion having the same height as a first plug portion on a handle portion of the plug is. For example, the handle section of the plug is connected to the first plug-in section of the plug and the handle section is provided with a circumferential bulge section which surrounds the first plug-in section and has the same height as the first plug-in section. A circumferential gap is formed between the bulge section and the first plug-in section. The gap serves to match a second plug-in section of the conductor socket on the physiotherapy device, so that the plug can be plugged into a physiotherapy device body whose Type-C socket is matched to the plug of the conductor and not into a device whose Type-C -Socket is not improved, such as a physiotherapy machine body with too large current or a mains voltage machine, can be plugged in to avoid injury to the human body. Furthermore, the first plug-in section has the same external shape as a plug-in section of a Type-C plug, and the bulge section is point-symmetrical with respect to the center line of the first plug-in section. Therefore, the connector of the conductor improved according to the embodiment of the application can be inserted in both normal and reverse orientation, providing good usability and improved user experience.

It will be on 1 pointed out. 1 shows a schematic structural view of a head of a physiotherapy device according to an exemplary embodiment of the present application. 2 shows an enlarged schematic structural view of point A according to 1 . 3 shows a schematic structural sectional view through BB according to 2 . According to one aspect of the present application, an embodiment of the application provides a conductor 100 of a physical therapy device. The conductor 100 includes a plug 110 and a wire 120. A first end of the wire 120 is electrically connected to the plug 110 and a second end of the wire 120 is used for electrical connection bonding with an electrode plate. The plug 110 includes a handle section 111 and a first plug section 112; a first end of the handle portion 111 is connected to the wire 120 and a second end of the handle portion 111 is connected to the first plug portion 112; the first plug-in section 112 has the same external shape as a plug-in section of a Type-C plug. The second end of the handle section 111 is further provided with a circumferential bulge section 113, which surrounds the first plug-in section 112 and has the same height as the first plug-in section 112. The bulge portion 113 is with respect to a center line (see the dashed line in 2 ) of the first plug-in section 112 point-symmetrically. A circumferential gap 1131 is formed between the bulge section 113 and the first plug-in section 112, which serves to match a second plug-in section of a conductor socket on a physiotherapy device.

The electrical connection of the second end of the wire 120 to the electrode plate can be made by connecting via a pin 130 or a button to the electrode plate. Two ends of the wire 120 are electrically connected to the connector 110 and the electrode pad, respectively, to transmit an electrical signal received by the connector 110 to the electrode pad. The electrode plate is in contact with the human body to perform physical therapy on the human body.

The second end of the handle section 111 is connected to the first plug-in section 112, so that the first plug-in section 112 is attached to the handle section 111. To provide the second end of the handle section 111 with a circumferential bulge section 113, it is conceivable that the bulge section 113 is formed in one piece with the handle section 111 or that the bulge section 113 is attached to the handle section 111 by, among other things, gluing (for example gluing using an adhesive) or welding.

The mating section of the Type-C connector has a center line and the mating section is point-symmetrical with respect to its center line, so that the Type-C connector can be plugged in both normal and reverse orientation. Since the first plug-in section 112 has the same external shape as the plug-in section of the Type-C plug, the first plug-in section 112 also has a center line and the first plug-in section 112 is designed point-symmetrically with respect to its center line. That is, after rotating about the center line by 180°, the first plug-in section 112 overlaps with the first plug-in section 112 before it is rotated. It is understood that each sectional surface of the first plug-in section 112 that runs perpendicular to the center line of the first plug-in section 112 is point-symmetrical with respect to the center point (for example, the intersection of the two dashed lines of the first plug-in section 112 according to 3 ) of this cutting surface. The center point is the intersection of the respective cutting surface of the first plug-in section 112 and its center line. Along a direction perpendicular to the center line of the first plug-in section 112, the first plug-in section 112 can be decomposed into a plurality of cut surfaces, each of which is point-symmetrical with respect to its own center.

The bulge section 113 is point-symmetrical with respect to the center point of the center line of the first plug-in section 112. That is, after rotating about the center line of the first plug-in section 112 by 180 °, the bulge section 113 overlaps with the bulge section 113 before rotating it. It is understood that each cut surface of the bulge section 113 that runs perpendicular to the center line of the first plug-in section 112 is point-symmetrical with respect to the center of this cut surface. Along a direction perpendicular to the center line of the first plug-in section 112, the bulge section 113 can be decomposed into a plurality of cut surfaces, each of which is point-symmetrical with respect to its own center.

In the case of the conductor 100 of a physiotherapy device according to the exemplary embodiments of the application, the bulge section 113 of the plug 110 surrounds the first plug-in section 112 and a circumferential gap 1131 is formed between the bulge section and the first plug-in section 112. The gap 1131 is used to match the second plug-in section of the conductor socket on the physiotherapy device, so that the plug 110 can be plugged onto a physiotherapy device body that is matched to the plug of the conductor. The bulge section 113 has the same height as the first plug-in section 112, so that the first plug-in section 112 is restricted when inserted into a Type-C socket that is not matched to the bulge section 113 and therefore the plug 110 cannot be inserted into a device. whose Type-C socket is not improved, such as a physiotherapy machine body with too large current or a mains voltage machine, can be inserted to avoid injury to the human body. Furthermore, the first plug portion 112 has the same external shape as the plug portion of the Type-C connector 110, and the bulge portion 113 is point-symmetrical with respect to the center line of the first plug portion 112. Therefore, the Ste cker 110 of the conductor 100 of the physiotherapy device improved according to the embodiment of the application can be inserted in both normal and reverse orientation, which ensures good usability and improved user experience.

In an optional embodiment, the bulge portion 113 is made of an insulating material.

If there is an electrical leakage of the physiotherapy device during use, the bulge section 113 will be under voltage if the bulge section 113 is not insulated. If the human body accidentally touches the bulge portion 113, the human body will be electrocuted. By making the bulge portion 113 of an insulating material, the probability that the bulge portion 113 is energized can be reduced, thereby reducing the risk of electric shock to the human body.

In an optional embodiment, the handle portion 111 and the bulge portion 113 are injection molded in one piece.

The handle portion 111 and the bulge portion 113 are injection molded in one piece, thereby increasing the structural stability between the bulge portion 113 and the handle portion 111. It can thus be prevented that the bulge section 113 cannot be secured against incorrect insertion due to deformation and thus the plug 110 can be plugged into another physiotherapy device or a device with mains voltage, or that the plug 110 cannot be inserted into one as a result of a deformation of the bulge section 113 The conductor socket of the physiotherapy device matched to the plug 110 can be plugged in.

It will be on 3 pointed out. In an optional embodiment, the length a of the bulge section 113 is smaller than the length b of the handle section 111 and the width c of the bulge section 113 is smaller than the width d of the handle section 111.

The length a and the width c of the bulge section 113 are smaller than the length b and the width d of the handle section 111, respectively, which reduces the material consumption of the bulge section 113 and saves costs. Furthermore, the dimension of the handle portion 111 is larger than that of the bulge portion 113, making it easier for users to grip and improving the user experience.

It will be on 3 pointed out. In an optional exemplary embodiment, the distance from the inner wall 1132 of the bulge section to the outer wall 1123 of the first plug-in section is 0.7 to 1.1 mm.

By having the distance from the inner wall 1132 of the bulge section to the outer wall 1123 of the first plug-in section in this range, a suitable size of the gap 1131 between the bulge section 113 and the first plug-in section 112 is achieved, thereby facilitating the insertion and unplugging of the plug 110 .

In an optional exemplary embodiment, the distance from the inner wall 1132 of the bulge section to the outer wall 1123 of the first plug-in section is 0.85 to 0.95 mm.

Because the distance from the inner wall 1132 of the bulge section to the outer wall 1123 of the first plug-in section is in this range, inserting and unplugging the plug 110 is made easier.

In an optional embodiment, the wall thickness of the bulge portion 113 is 0.9 to 1.4 mm.

By having the wall thickness of the bulge portion 113 in this range, the bulge portion 113 is not susceptible to deformation even under the influence of an external force or when the plug 110 is repeatedly plugged in and unplugged.

In an optional embodiment, the wall thickness of the bulge portion 113 is 1.1 to 1.3 mm.

The thickness of the bulge portion 113 in this area is appropriate. By not making the bulge section 113 excessively thick, material can be saved. Also, by not making the bulge portion 113 excessively thin, the bulge portion 113 is not susceptible to deformation.

The connector of an existing physical therapy device conductor has round pins. When the physical therapy device body transmits different signals to different wires, a connector can only be connected to two wires due to the limited number of signal pins of the connector. If the physiotherapy machine body is to transmit different signals of four types to four wires, then two connectors are required and must be connected to the physiotherapy machine An additional conductor socket must also be provided, which increases costs.

It will be on 1 and 4 pointed out. 4 shows a schematic structural view of a contact pin in the first plug-in section 112 according to an exemplary embodiment of the present application. In view of the above problem, in the head of a physiotherapy device according to an exemplary embodiment of the application, it is provided that a first layer of contact pins 1121 and a second layer of contact pins 1122 are arranged on the first plug-in section 112. Both the number of contact pins of the first layer of contact pins 1121 and the number of contact pins of the second layer of contact pins 1122 are N and N ≥ 4, where N is an integer. The first layer of contact pins 1121 and the second layer of contact pins 1122 are arranged point-symmetrically with respect to the center line of the first plug-in section 112 and contact pins of the first layer of contact pins 1121 and the second layer of contact pins are arranged point-symmetrically with respect to the center line of the first plug-in section 112 1122 each form a pair of contact pins. The number of wire 120 is also N. A first end of each of the wires 120 is electrically connected to one of the pairs of contact pins and a second end of each of the wires 120 is electrically connected to a pin 130. Each of the plug pins 130 is electrically connected to one of the pairs of contact pins via the respective wire 120 in order to receive a signal transmitted through the conductor socket.

The principle of the point-symmetrical arrangement of the first layer of contact pins 1121 and the second layer of contact pins 1122 with respect to the center line of the first plug-in section 112 is similar to the above-mentioned principle of the point-symmetrical arrangement of the bulge section 113 with respect to the center line of the first plug-in section 112. After rotating of the plug 110 around the center line of the first plug portion 112 by 180°, the first layer of contact pins 1121 overlaps with the original position of the second layer of contact pins 1122 and the second layer of contact pins 1122 overlaps with the original position of the first layer of contact pins 1121. In In detail, the leftmost contact pin of the first layer of contact pins 1121 overlaps with the original position of the rightmost contact pin of the second layer of contact pins 1122 and the rightmost contact pin of the second layer of contact pins 1122 overlaps with the original position of the leftmost contact pin the first layer of contact pins 1121. By arranging the two layers of contact pins of the first plug-in section 112 point-symmetrically with respect to the center line of the first plug-in section 112, it is ensured that an electrical connection is established when the first plug-in section 112 is plugged in both with normal and reverse Plug alignment can be made into the conductor socket of the physiotherapy device.

By providing the wire 120 in a number of N, the first end of the single wire 120 is electrically connected to one of the contact pin pairs of the two layers of contact pins of the first plug portion 112, and the second end of each of the wires 120 is electrically connected to a plug pin 130, respectively and each of the pins 130 is electrically connected to one of the pairs of contact pins via the respective wire 120, the pins 130 can receive various signals transmitted by the physical therapy device body 210 via the connector 110 and the wires 120 to meet user requirements for various physical therapy effects fulfill. Since a plug 110 can be connected to four or more wires 120, the number of the plug 110 and the number of the conductor socket on the physiotherapy device body can be reduced, thus saving costs.

It will be on 5 pointed out. 5 shows a schematic structural view of a physiotherapy device 200 according to an exemplary embodiment of the present application. 6 shows a schematic partial structural view of a physiotherapy device body 210 according to an embodiment of the present application. 7 shows a schematic structural sectional view through CC according to 5 . According to another aspect of the embodiments of the application, an embodiment of the application provides a physical therapy device 200 that includes a physical therapy device body 210 and the conductor 100 according to one of the above embodiments. A conductor socket is provided on the physiotherapy device body 210, which serves for electrical connection to the plug 110 of the conductor 100.

As in 6 shown, the conductor socket includes in detail a second plug-in section 211 and a tongue 212. The external shape of the second plug-in section 211 can be the same as that of the second plug-in section of a Type C socket. A gap 213 is present between the physiotherapy device body 210 and the second plug-in section 211. How out 7 results, the first plug-in section 112 is inserted into the second plug-in section 211 when the plug 110 of the conductor 100 is matched to the conductor socket on the physiotherapy device 210, and the contact pins on the tongue 212 are electrically connected to the respective contact pins on the first plug-in section 112 . The second plug-in section 211 is inserted into the gap 1131 between the bulge section 113 and the first plug-in section 112 is inserted and the bulge section 113 is inserted into the gap 213 between the physiotherapy device body 210 and the second plug-in section 211.
