Referring to fig. 1 and 2, in the hydraulic travel switch 10 in an embodiment, a hydraulic pressure generated by a liquid is utilized to generate a larger thrust and a proper travel, and the hydraulic travel switch is used as a control switch of other mechanisms, so that the control mode is simple and the cost is low. In particular, in this embodiment, the hydraulic travel switch 10 includes a housing 100, a flexible seal 200, a push rod assembly 300, and a spring 400.
Referring to fig. 4 and fig. 5, the housing 100 is hollow to form a receiving cavity 100a, and the housing 100 is provided with a liquid inlet 101 and a through hole 102. Specifically, the housing 100 includes an upper housing 110 and a lower housing 120, the upper housing 110 has a first opening end, the lower housing 120 has a second opening end, and the first opening end of the upper housing 110 is disposed at the second opening end of the lower housing 120 to jointly enclose a housing cavity 100a. Therefore, the upper housing 110 and the lower housing 120 can be manufactured separately, so that the demolding is convenient, and the process is simple. Of course, in other embodiments, the housing 100 may also be an integrally formed structure.
The liquid inlet 101 is formed at the bottom of the lower housing 120, and the through hole 102 is formed at the top of the upper housing 110. The bottom of the lower housing 120 is located below the top of the upper housing 110 based on the up-down direction in fig. 1, so that an upward thrust is generated by the hydraulic pressure after the liquid is introduced from the liquid inlet 101. The liquid inlet 101 may be further provided with a liquid inlet connector 103, and a liquid inlet channel 104 is formed on the liquid inlet connector 103, and the liquid inlet channel 104 is communicated with the liquid inlet 101. By arranging the liquid inlet joint 103, the water inlet pipe 20 can be connected more conveniently, and a control valve 30 can be arranged on the water inlet pipe 20, and the control valve 30 controls the opening and closing of the water inlet pipe 20.
The flexible seal ring 200 has an inner ring 210 and an outer ring 220, the outer ring 220 being secured to the housing 100, the inner ring 210 being secured to the pushrod assembly 300. Specifically, outer ring 220 of flexible seal ring 200 is secured between the first open end and the second open end. The flexible sealing ring 200 can be made of rubber leather bags, and when liquid is introduced into the liquid inlet 101, the rubber leather bags are not easy to burst due to good flexibility.
Referring to fig. 2, the first opening end has a first pressing portion 111 and a first abutting portion 112, and the first pressing portion 111 is disposed next to the first abutting portion 112. The second opening end has a first limiting portion 121, a second pressing portion 122, and a second abutting portion 123, and the second pressing portion 122 connects the first limiting portion 121 and the second abutting portion 123. Specifically, the first limiting portion 121, the second pressing portion 122, and the second abutting portion 123 may form a cross-sectional structure similar to a "U" shape, in which the height of the second abutting portion 123 is higher than the height of the first limiting portion 121. The first limiting portion 121 and the first pressing portion 111 have a space therebetween to form a first inlet.
The outer ring 220 has a first flexible portion 221, a third pressing portion 222, and a third abutting portion 223, the third pressing portion 222 is pressed between the first pressing portion 111 and the second pressing portion 122, the third abutting portion 223 abuts between the first abutting portion 112 and the second abutting portion 123, and the first flexible portion 221 is located at the first inlet. By fixing the outer ring 220 of the flexible seal ring 200 between the first open end of the upper case 110 and the second open end of the lower case 120 in the above manner, the firmness between the flexible seal ring 200 and the upper case 110 and the lower case 120 can be improved. Of course, in other embodiments, the flexible seal ring 200 may be secured to the housing in other ways. For example, outer ring 220 of flexible seal ring 200 may be secured to upper housing 110 or lower housing 120 by glue.
Referring to fig. 3, the push rod assembly 300 includes a push plate 310 and a push rod 320, wherein the push plate 310 is accommodated in the accommodating cavity 100a. One end of the push rod 320 is disposed on the push plate 310, and the other end of the push rod 320 can extend out of the accommodating cavity 100a through the through hole 102. Specifically, the push rod 320 may be integrally formed with the push rod 320, and the push plate 310 has a substantially circular plate-like structure, so that the cross-sectional shapes of the push plate 310 and the housing 100 are substantially the same, so that the push plate 310 can move up and down in the accommodating cavity 100a.
The inner ring 210 of the flexible seal ring 200 is secured to the stem 320 assembly 300. Specifically, the push rod assembly 300 further includes a pressing block 330, where the pressing block 330 is disposed on a side of the push plate 310 facing the liquid inlet 101, and the inner ring 210 is fixed between the pressing block 330 and the push plate 310. The pressing block 330 is fixed to the push plate 310 by means of glue. For example, the pressing block 330 may be adhered to the pressing plate 310 by applying glue to the surface of the pressing plate 310 facing the pressing block 330 and/or the surface of the pressing block 330 facing the pressing plate 310. The push plate 310 may further be formed with a bump 311 to increase the coating area of the glue and increase the adhesion between the pressing block 330 and the push plate 310. Of course, in other embodiments, the pressure block 330 may also be secured to the push plate 310 by ultrasonic welding. Or may be otherwise secured so long as the securing of the pressure block 330 to the push plate 310 is accomplished.
The push plate 310 is formed with a second limiting portion 312 and a fourth pressing portion 313, and the second limiting portion 312 is disposed next to the fourth pressing portion 313. The pressing block 330 is formed with a fifth pressing portion 331, the inner ring 210 has a second flexible portion 211 and a sixth pressing portion 212, a second spacing portion 312 and the fifth pressing portion 331 are spaced apart to form a second inlet, the sixth pressing portion 212 is pressed between the fourth pressing portion 313 and the fifth pressing portion 331, and the second flexible portion 211 is located at the second inlet. By fixing the inner ring 210 of the flexible seal ring 200 between the push plate 310 and the pressing block 330 in the above manner, the firmness between the flexible seal ring 200 and the push rod assembly 300 can be improved. Of course, in other embodiments, the press block 330 may be omitted and the inner ring 210 of the flexible seal ring 200 may be directly fixed to the push rod assembly 300, for example, to the push plate 310.
Referring to fig. 2 again, the inner sidewall of the housing 100 with the liquid inlet 101 is further formed with a protrusion 124, and the pressing block 330 can contact with the protrusion 124. Specifically, the protrusion 124 is formed on the bottom wall of the lower case 120. The bulge 124 is arranged, when the pressing block 330 contacts with the bulge 124, line contact is formed, a certain space is reserved between the pressing block 330 and the bottom wall of the lower shell 120, and when the liquid inlet 101 is filled with water, the area of pressure distribution is larger at the beginning, so that pressure balance of the pressing block 330 and the pushing plate 310 is guaranteed.
Referring to fig. 1 and 3 again, the spring 400 is sleeved on the push rod 320. The flexible sealing ring 200 and the pushing plate 310 jointly divide the accommodating cavity 100a into a first cavity 100b and a second cavity 100c which are not communicated with each other and have variable volumes, the liquid inlet 101 is communicated with the first cavity 100b, and the through hole 102 is communicated with the second cavity 100 c. The side wall of the casing 100 provided with the through hole 102 is extended outwards to form an extension tube 130, the extension tube 130 is communicated with the through hole 102, the other end of the push rod 320 can extend out of the extension tube 130, and an accommodating space 140 for accommodating the spring 400 is formed between the inner side wall of the extension tube 130 and the outer side wall of the push rod 320.
The specific working principle of the hydraulic travel switch 10 is as follows:
referring to fig. 1 and 4, when the hydraulic travel switch 10 needs to be turned on, liquid is introduced into the liquid inlet 101, the hydraulic pressure is much greater than the pressure of the spring 400, the push plate 310 moves away from the liquid inlet 101 under the pushing action of the liquid, the volume of the first cavity 100b gradually increases, the volume of the second cavity 100c gradually decreases, the push plate 310 drives the push rod 320 to move away from the liquid inlet 101, and the push rod 320 can act on other mechanisms to control the other mechanisms to be turned on.
Referring to fig. 5, when the push plate 310 touches the inner side wall of the upper housing 110, the entire stroke is terminated, and the stroke h is as shown in fig. 5. The height of the receiving cavity 100a of the upper housing 110 and the lower housing 120 can be changed to adjust the stroke h according to the actual requirement. When the maximum stroke is reached, the flexible seal ring 200 is attached to the inner side wall of the upper case 110, and the liquid pressure acts on the inner side wall of the upper case 110 through the flexible seal ring 200. At this time, no matter how large the hydraulic pressure is, the flexible sealing ring 200 will not burst, so that the hydraulic travel switch 10 is not damaged under abnormal impact of the water inlet pipeline, and still can continue to work normally.
The thrust force of the push rod 320 is equal to the pressure of the liquid against the push plate 310 minus the pressure of the spring 400 against the push plate 310, wherein the liquid pressure is proportional to the inlet pipe pressure P and the bottom area S of the push plate 310 pressed, and the spring 400 pressure is proportional to the total deformation, so the thrust force of the push rod 320 is f= P.S-k (a+x), where k is the spring 400 elastic coefficient, a is the pre-pressing amount, and x is the deformation in the motion stroke of the push rod 320.
When the inlet 101 is connected with a household tap water pipe, the water pressure of the household tap water pipe is generally 2kg/cm 2 ～5kg/cm 2 So that a relatively large hydraulic pressure can be generated with a small foot print, e.g. a foot print s=12.56 cm with a diameter of 4cm 2 Pressures of about 251N to 628N may be generated. The spring 400 is used for drainage and reset, and a smaller force is selected, compared with the large water pressure, the pressure of the spring 400 is negligible, so that the push rod 320 finally generates a pushing force slightly smaller than the water pressure. This feature can be used for some mechanisms requiring a large opening force, and can also make the overall hydraulic travel switch 10 compact.
When the liquid is stopped from being introduced into the liquid inlet 101, the hydraulic pressure disappears, the push plate 310 moves towards the direction close to the liquid inlet 101 under the action of the restoring force of the spring 400, the liquid in the first cavity 100b is discharged through the liquid inlet 101, the volume of the first cavity 100b is gradually reduced, the volume of the second cavity 100c is gradually increased, and the push rod 320 is restored to the initial position (as shown in fig. 1) under the driving of the push plate 310, so that other mechanisms are controlled to be closed. The hydraulic travel switch 10 generates a large thrust force by introducing liquid into the liquid inlet 101 to generate a hydraulic pressure, and pushes the push plate 310 and the push rod 320 to move to generate a proper travel, so that the hydraulic travel switch is used as a control switch of other mechanisms, and therefore, the control mode is simple and the cost is low.
The invention also provides a toilet, which comprises a toilet body and a flushing mechanism, wherein the flushing mechanism is used for flushing the toilet body. The flushing mechanism comprises a water storage tank, a valve connecting rod mechanism and the hydraulic travel switch 10, wherein the water storage tank is used for storing water, a valve is arranged on the water storage tank, the valve connecting rod mechanism is connected with the valve, and the hydraulic travel switch 10 controls the opening and closing of the valve through the valve connecting rod mechanism.
Because the hydraulic travel switch 10 is used in the toilet and the flushing mechanism, when the liquid inlet 101 is filled with liquid, the push rod 320 pushes the valve link mechanism to act, the valve of the water storage tank is controlled to be opened, and the water stored in the water storage tank washes the toilet body. When the liquid inlet 101 stops introducing liquid, the push rod 320 returns to the initial position under the action of the restoring force of the spring 400, and the valve link mechanism returns to the initial state to control the valve of the water storage tank to be closed, so that the control mode is simple and the cost is low.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
