Disclosure of Invention
In view of the deficiencies of the prior art, the present invention provides a cleaner comprising at least two cleaning bodies disposed on a cleaning mechanism having a first central axis as a rotation axis. The cleaning mechanism at least comprises a first hinge point and a third hinge point which are respectively positioned on two ends of the first connecting rod, and a second hinge point and a fourth hinge point which are respectively positioned on two ends of the second connecting rod. The second connecting rod is hinged with the rod part of the first connecting rod through the third hinge point to form a connecting line of the first hinge point and the fourth hinge point, and the connecting line is kept in a working state parallel to the first central axis at all times. And a cleaning body is arranged on the third hinged point. The cleaning body is driven to rotate to complete cleaning work based on the fact that the first connecting rod and the second connecting rod rotate around the first central axis together. Under the condition that the fourth hinge point is fixed, the change of the first distance between the first hinge point and the fourth hinge point drives the second distance between the third hinge point and the first central axis to increase or decrease so as to form the working state that the cleaning body is suitable for cleaning pieces with different inner diameters.
According to a preferred embodiment, the first connecting rod is divided into two separate connecting rods by a compression spring arranged thereon and nested by a limiting sleeve. The two independent connecting rods are connected through the compression spring to form an operating form enabling the length of the first connecting rod to be reduced based on compression of the compression spring.
According to a preferred embodiment, the washing mechanism further comprises a second sleeve nesting the first sleeve. The first sleeve and the second sleeve are connected through a sliding pair to form a mutually-sliding working form. The first central axis coincides with an axis of the first sleeve. The first connecting rod is connected with the second sleeve through the first hinge point, and the second connecting rod is connected with the first sleeve through the fourth hinge point. Increasing or decreasing the first distance based on sliding the second sleeve in a direction parallel to the first central axis.
According to a preferred embodiment, the two ends of the first sleeve define a first extreme position closest to said fourth hinge point and a second extreme position furthest from said fourth hinge point. When the second sleeve is located at the second limit position, the axial direction of the first connecting rod is parallel to the first central axis, and therefore a shape that the vertical distance between the third hinge point and the first central axis is minimum is defined. When the second sleeve is located at the first limit position, the axial direction of the first connecting rod is perpendicular to the first central axis, and therefore a shape of the third hinge point with the largest perpendicular distance from the first central axis is defined.
According to a preferred embodiment, the cleaner further comprises a rotator-shaped housing having a hollow cavity and an axial direction parallel to the first central axis, and a push rod portion, a transmission portion and a unidirectional rotation portion which are embedded in the hollow cavity. Two fixing holes are arranged at the middle position of the rotator-shaped shell along the axial direction of the rotator-shaped shell in a mirror symmetry mode relative to the first central axis. The end face of the rotary body-shaped shell is perpendicular to the upper end part and the lower end part of the first central axis, and a first through hole and a second through hole are formed in the upper end part and the lower end part of the first central axis respectively. And a first mounting web plate with a third through hole and a second mounting web plate with a fourth through hole are respectively arranged at the upper side position and the lower side position of the rotator-shaped shell along the extending direction of the first central axis. The central axes of the first through hole, the second through hole, the third through hole and the fourth through hole are all coincided with the first central axis.
According to a preferred embodiment, the pusher section comprises at least a pusher rod, a rack and a return spring. The rack and the push rod are connected in a mode that respective central axes of the rack and the push rod are coincident with the first central axis, and a working state that the push rod penetrates through the first through hole and the rack penetrates through the second through hole is formed. The push rod is connected with the first installation web plate through at least two return springs. When the pushing rod is under the action of an external force parallel to the direction of the first central axis, the return spring presents a compression trend, and when the external force disappears, the pushing rod automatically returns to the initial position based on the elastic potential energy of the return spring.
According to a preferred embodiment, the transmission comprises at least a first bevel gear and a pinion mounted on the first shaft. The first rotating shaft is connected with the rotary body-shaped shell in a mode that two end parts of the first rotating shaft are respectively inserted into the fixing holes, and forms an operating mode of rotating around the central axis of the first rotating shaft. The rack is connected with the pinion in a gear meshing mode and indirectly drives the first bevel gear to rotate based on the sliding of the rack.
According to a preferred embodiment, the unidirectional rotation portion comprises at least a second bevel gear and a ratchet portion mounted on the second rotation shaft. The second bevel gear is connected with the first bevel gear in a gear meshing manner. And the second rotating shaft is fixed on the second mounting web plate in a mode of penetrating through the fourth through hole. The ratchet part at least comprises a circular ratchet body, a plurality of ratchet teeth which are regularly distributed in the circular ratchet body and a spring push rod matched with the ratchet teeth. The ratchet teeth are defined by a first plane and a second plane which are parallel to the first central axis, and the working state that the circular ratchet body rotates around the first central axis is formed based on the extrusion force of the spring push rod applied to the first plane. Based on the relative sliding between the second plane and the spring push rod, the working state that the spring push rod is compressed and shortened and the ratchet wheel tooth is kept still is formed.
The invention also provides an inner wall cleaning device, which is provided with the cleaner and also comprises a rotating rod. One end of the rotating rod is connected with the second rotating shaft to form a working state that the rotating rod is driven to rotate around the first central axis based on the rotation of the second rotating shaft.
According to a preferred embodiment, the rotary lever is nested by the first sleeve and is connected to the first sleeve by means of a sliding pair so as to form an operating configuration capable of producing mutual sliding in a direction parallel to the first central axis. The rotating rod is further fixed with the first sleeve in a mode that a spring positioning pin is inserted into a pin hole so as to form a working state that relative rotation is not generated between the rotating rod and the first sleeve.
The invention has the beneficial technical effects that:
(1) the inner wall cleaning device has the advantages of being wide in application range and convenient to operate due to the fact that the inner wall cleaning device is simple in structure and convenient to disassemble, all parts can be used independently and driven in a hand pressing mode.
(2) The inner wall cleaning device can be used after being disassembled, and the problem that time is consumed due to the fact that the assembly is needed according to the specification after the disassembly is carried out in the traditional accessory packaging mode is solved. At the same time, the space required for packaging is minimized and the complexity of the packaging is reduced.
(3) The invention can make up for the small difference between the opening size of the cleaning body and the actual inner diameter of the inner wall of a beaker or a glass cup, for example, by arranging the compression spring nested by the limiting sleeve on the connecting rod. Meanwhile, the extrusion force on the inner wall can be reduced to protect the inner wall from being damaged.

Example 1
A sanitary fitting comprises at least a washing mechanism 3. Can be used separately and packaged for sale. The power supply mechanism can be connected with the power supply mechanism for use through the connecting point 1. The power supply mechanism may be an electric motor driven by electricity. After the motor is connected with the cleaning mechanism 3 through the connecting point 1, a more labor-saving cleaning process can be realized.
As shown in fig. 2, the cleaning mechanism 3 includes at least a first hinge point 56, a second hinge point 57, and a third hinge point 58 which are maintained in a collinear state with each other. And a fourth hinge point 59 that remains collinear with the first hinge point 56. Preferably, the line connecting the first hinge point 56 and the fourth hinge point 59 is always parallel to the first central axis 4. The operating mode, in which the second distance between the third articulation point 58 and the first central axis 4 is dynamically varied, is formed on the basis of a variation of the first distance between the first articulation point 56 and the fourth articulation point 59. Preferably, the first hinge point 56, the third hinge point 58, the second hinge point 57 and the fourth hinge point 59 are defined by the ends of the first link 16 and the second link 17. Wherein, the first link 16 and the second link 17 are connected through the second hinge point 57 to form the link mechanism 15, and the first link 16 and the second link 17 can rotate around the second hinge point 57. Preferably, the second hinge point 57 and the fourth hinge point 59 are both end portions of the second link 17. The first hinge point 56 and the third hinge point 58 are both end portions of the first link 16.
Preferably, the washing mechanism 3 further comprises a second sleeve 7 for nesting the first sleeve 6 and is capable of forming an operating configuration of the second sleeve 7 sliding relative to the first sleeve 6 along a central axis thereof. The sliding mode between the two can be designed according to the practical application environment. For example, the mutual sliding of the two is realized by arranging a sliding groove similar to the umbrella rod of an umbrella. Wherein the fourth hinge point 59 and the first hinge point 56 are arranged on the first sleeve 6 and on the second sleeve 7, respectively.
Preferably, the cleaning body 18 is disposed on the third hinge point 58. As the distance between the first hinge point 56 and the fourth hinge point 59 increases, the vertical distance between the third hinge point 58 and the first central axis 4 also gradually increases. As the distance between the first hinge point 56 and the fourth hinge point 59 decreases, the perpendicular distance between the third hinge point 58 and the first central axis 4 also decreases gradually. It is thereby possible to form the cleaning body 18 with different radii of gyration to accommodate inner wall cleaning members of different inner diameter dimensions. For example, when washing test tubes and beakers, only the distance between the first hinge point 56 and the fourth hinge point 59 needs to be adjusted to dynamically adapt to the washing of both.
Preferably, in order to fix the relative positions of the first sleeve 6 and the second sleeve 7 in the working state, the first sleeve 6 is provided with a plurality of second positioning pin holes 11 which are linearly arranged at intervals along the axial direction of the first sleeve 6. The second sleeve 7 is provided with at least one third dowel hole 12. The fixing of the relative positions of the first sleeve 6 and the second sleeve 7 is accomplished based on the insertion of the second spring positioning pin 13 into the second positioning pin hole 11 and the third positioning pin hole 12. Preferably, the working mode of dynamically changing the fourth distance between the third hinge point 58 and the connection point 1 is formed based on the insertion of the second spring positioning pin 13 into the second positioning pin hole 11 at different positions.
As shown in fig. 1 and 2, washing mechanism 3 further includes a first spring-loaded detent pin 10 and a rotating rod 5 nested by first sleeve 6. Preferably, the first sleeve 6 and the rotating rod 5 constitute a telescopic mechanism 14. The first sleeve 6 can also form an operation form in which the first sleeve 6 can slide relative to the rotating rod 5 along the central axis direction thereof after nesting the rotating rod 5 to form the telescopic mechanism 14 with different lengths. Preferably, the sliding mode between the two can be specifically designed according to the practical application environment. For example, the mutual sliding of the two is realized by arranging a sliding groove similar to the umbrella rod of an umbrella. The cleaning body 18 can be fed into the inner wall-shaped cleaning parts with different diameters, such as test tubes, glasses and the like, through the telescopic mechanism 14 with variable length, so that the application range of the inner wall cleaning device is improved.
Preferably, the rotating rod 5 is provided with a plurality of first positioning pin holes 9 arranged at intervals linearly along the axial direction thereof. The fixing of the relative position of the rotating lever 5 and the first sleeve 6 is accomplished based on the insertion of the first spring positioning pin 10 into the first positioning pin hole 9 and the second positioning pin hole 11. The telescopic mechanism 14 can have working forms with different lengths based on the fact that the first spring positioning pin 10 is inserted into the first positioning pin hole 9 at different positions.
It is preferable to avoid the positions of the first spring positioning pin 10 and the second spring positioning pin 13 from interfering with each other. The second one of the second dowel holes 11 closest to the connection point 1 is selected for use solely by the first spring dowel 10. Preferably, as shown in fig. 5, the first spring positioning pin 10 and the second spring positioning pin 13 each have a shorter first rod and a longer second rod. Wherein the longer second rod is nested by a spring, and the first rod, the second rod and the spring are all arranged in a hollow cavity. The working state of the spring is a compressed state. The first rod is inserted into the positioning pin hole and kept fixed based on the elastic potential energy generated by the compression of the spring. When the positioning pin hole into which the first rod is inserted needs to be switched, the end part of the second rod with a longer length is manually grabbed, external force is applied, and the first rod is completely contracted into the hollow cavity. When moving to the designated dowel hole, the end of the second rod is released by the release hand, and the first rod is inserted into the designated dowel hole based on the elastic potential energy generated by the compression of the spring.
As shown in fig. 1, 2 and 3, the second positioning pin hole 11 further comprises a first extreme position pin hole 20 close to the connection point 1 and a second extreme position pin hole 21 farthest from the connection point 1. In the condition that the second sleeve 7 is fixedly connected with the first sleeve 6 through the first extreme position pin hole 20, the axial direction of the first connecting rod 16 is parallel to the first central axis 4 and thereby defines a mode that the vertical distance between the third hinge point 58 and the first central axis 4 is minimum. In the case where the second sleeve 7 is fixedly connected to the first sleeve 6 via the second extreme position pin hole 21, the axial direction of the first link 16 is perpendicular to the first central axis 4 and thus defines a configuration in which the perpendicular distance of the third hinge point 58 from the first central axis 4 is the greatest. The configuration of the inner wall cleaning apparatus as shown in figure 3 minimizes the packaging complexity by minimizing the space required for the package in a ready-to-use-as-unpack condition. Meanwhile, the problem that time is consumed due to the fact that the assembly is needed according to the specification after unpacking in the traditional accessory packaging mode is solved.
Preferably, as shown in fig. 1, the cleaning mechanism 3 includes at least one cleaning portion 19 composed of a first link 16, a second link 17, and a cleaning body 18. Preferably, when the washing means 3 comprises two or more cleaning portions 19, the cleaning portions 19 surround the first central axis 4 in an annularly uniform manner. Preferably, the cleaning body 18 may be one of sponge, cotton cloth and cotton or selected according to the actual use environment. For example, when removing rust from the inner wall, the cleaning body 18 may be a steel ball brush, a wire ball, or the like.
Preferably, the length of the second link 17 is one third to one half of the first link 16. The first hinge point 56 is spaced from the second hinge point 57 by a distance of one third to one half of the first link 16.
Example 2
This embodiment is a further improvement of embodiment 1, and repeated contents are not described again.
A cleaning device comprises a first central axis 4 and a connection point arranged on a cleaning mechanism 3. The cleaning mechanism 3 includes at least a fourth hinge point 59 and a first hinge point 56, a second hinge point 57 and a third hinge point 58 which are kept in a collinear state with each other. Wherein the operating mode in which the second distance between the third articulation point 58 and the first central axis 4 is dynamically varied is formed on the basis of a variation of the first distance between the first articulation point 56 and the fourth articulation point 59.
The working mode of the third hinge point 58 is formed by the dynamic change of the third distance from the second hinge point 57 based on the external force applied to the third hinge point. The third hinge point 58 is provided with the cleaning body 18. Wherein the cleaning body 18 is rotated about the first central axis 4 to perform the cleaning operation.
Preferably, the washing mechanism 3 further comprises a second sleeve 7 for nesting the first sleeve 6. And a first link 16 and a second link 17 hinged through a second hinge point 57. Wherein the fourth hinge point 59 and the first hinge point 56 are arranged on the first sleeve 6 and on the second sleeve 7, respectively. The first hinge point 56, the third hinge point 58 and the fourth hinge point 59 are each defined by the ends of the first link 16 and the second link 17. Preferably, the first link 16 is divided into two separate links by a compression spring 23 disposed thereon and nested by a stop collar 22. Wherein the two separate links are connected by a compression spring 23 to form an operating configuration in which the length of the first link 16 can be finely adjusted based on the compression of the compression spring 23. Preferably, the ends of the divided first connecting rods are provided with blocking bodies. The two ends of the position-limiting sleeve 22 are respectively provided with a through hole so as to connect the two divided sections of the first connecting rods 16 with the compression springs 23 by being inserted into the through holes. The first connecting rod cannot be separated from the limiting sleeve through the blocking body. With the second sleeve 7 fixed, slight differences in the opening dimension of the cleaning body 18 from the actual inner diameter of the inner wall of, for example, a beaker or glass, can be compensated for by the compression spring 23. Meanwhile, the extrusion force on the inner wall can be reduced to protect the inner wall from being damaged. Preferably, with third hinge point 58 in a fixed position, the vertical distance of third hinge point 58 from first central axis 4 does not exactly match the inside diameter of a cleaning element, such as a test tube or beaker. It is very easy to cause the third hinge point 58 to press the inner wall too much due to the fact that the vertical distance between the third hinge point 58 and the first central axis 4 is slightly larger than the inner diameter of the cleaning member, which may cause the cleaning member to be broken when the cleaning member is a glass product. Through the compression spring 23 coated by the limiting sleeve 22, under the condition that the third hinged point 58 is subjected to overlarge extrusion force on the inner wall of the cleaning piece, the vertical distance between the third hinged point 58 and the first central axis 4 is finely adjusted based on the compression of the compression spring 23, so that the vertical distance is self-adaptive to the inner diameter of the inner wall, and the extrusion force between the cleaning body and the inner wall of the cleaning piece is kept in an ideal state. Preferably, the pressing force between the cleaning body and the inner wall of the cleaning element can be achieved by selecting compression springs of different hardness.
Preferably, as shown in fig. 1, the cleaning mechanism 3 includes at least one cleaning portion 19 composed of a first link 16, a second link 17, a compression spring 23, a stopper 22, and a cleaning body 18. Preferably, when the washing means 3 comprises two or more cleaning portions 19, the cleaning portions 19 surround the first central axis 4 in an annularly uniform manner. Preferably, the cleaning body 18 may be one of sponge, cotton cloth and cotton or selected according to the actual use environment. For example, when removing rust from the inner wall, the cleaning body 18 may be a steel ball brush, a wire ball, or the like.
Preferably, washing mechanism 3 further includes a first spring positioning pin 10, a second spring positioning pin 13, and a rotating rod 5 nested by first sleeve 6. Wherein, the rotating rod 5 and the first sleeve 6 are respectively provided with a plurality of first positioning pin holes 9 and a plurality of second positioning pin holes 11 which are linearly arranged at intervals along the respective axial direction.
