Description

Technical Field

[0001] This utility model relates to the field of water distribution valve technology, and in particular to a push-pull water distribution valve structure and a shower system. Background Technology

[0002] A water distribution valve is a valve structure that can control the direction of water flow. For existing water distribution valves, water flow switching is usually achieved by pushing the internal piston. However, the piston is easily affected by water pressure, resulting in a large thrust required to move the piston, which is not labor-saving or convenient to operate. Utility Model Content

[0003] This utility model aims to solve the technical problems existing in the prior art. To this end, this utility model proposes a push-pull water valve structure and a shower system, in which the piston is less affected by water pressure and requires less thrust.

[0004] The push-pull water distribution valve structure according to the first aspect of the present invention includes:

[0005] The valve body has a water distribution cavity inside. The outer peripheral wall of the valve body is provided with a first water outlet, a water inlet and a second water outlet that communicate with the water distribution cavity. The first water outlet, the water inlet and the second water outlet are arranged sequentially along the axial direction of the valve body. One end of the valve body along its axial direction also has an installation port that communicates with the water distribution cavity.

[0006] A fixed cylinder is inserted into the water distribution cavity through the installation port. The outer peripheral wall of the fixed cylinder is sealed to the inner wall of the water distribution cavity. The outer peripheral wall of the fixed cylinder is provided with a clearance hole and a water passage corresponding to the first water outlet.

[0007] A piston is disposed within the water distribution chamber and is capable of moving axially along the valve body. The piston includes a water distribution section located between the first water outlet and the second water outlet. The outer peripheral wall of the water distribution section is provided with a water distribution seal. When the water distribution seal abuts against the inner peripheral wall of the fixed cylinder, the water distribution section disconnects the water inlet from the first water outlet. When the water distribution seal abuts against the inner peripheral wall of the valve body, the water distribution section disconnects the water inlet from the second water outlet. When the water distribution seal is located at the water inlet, the water inlet is connected to the second water outlet.

[0008] A push button is fixedly connected to the piston to drive the piston to move, and the push button passes through the clearance hole.

[0009] The push-pull water distribution valve structure according to the embodiment of this utility model has at least the following beneficial effects: it can realize water output from the first outlet or the second outlet alone, and it can also realize water output from the first outlet and the second outlet simultaneously. When the first outlet and the second outlet output water at the same time, since the water distribution part is located between the first outlet and the second outlet, both sides of the water distribution part are subjected to water pressure. This can balance the force on the water distribution part. At this time, the water flow will not push the water distribution part to move. The water distribution part can remain in its original position, and the thrust that pushes the water distribution part to move is small, which can facilitate operation. This can improve the phenomenon that the piston is easily affected by water pressure.

[0010] According to some embodiments of the present invention, the piston further includes a first water-sealing part and a second water-sealing part. Along the axial direction of the piston, the water-distributing part is located between the first water-sealing part and the second water-sealing part. The outer peripheral wall of the first water-sealing part is provided with a first water-sealing cup, which abuts against the inner peripheral wall of the fixed cylinder. The outer peripheral wall of the second water-sealing part is provided with a second water-sealing cup, which abuts against the inner peripheral wall of the valve body.

[0011] According to some embodiments of the present invention, the first water-sealing bowl has a first annular V-groove facing the water-dividing part, and the second water-sealing bowl has a second annular V-groove facing the water-dividing part.

[0012] According to some embodiments of the present invention, the piston includes a first shaft and a second shaft, the outer diameters of the first shaft and the second shaft are both smaller than the outer diameter of the water distribution part, the first shaft is connected between the first water sealing part and the water distribution part, and the second shaft is connected between the second water sealing part and the water distribution part.

[0013] According to some embodiments of the present invention, the piston is provided with a threaded hole, the outer peripheral wall of the push button is provided with an external thread, and the push button is threadedly connected to the threaded hole through the external thread.

[0014] According to some embodiments of the present invention, the lower end of the fixed cylinder is provided with an opening, and the piston extends into the fixed cylinder through the opening.

[0015] The shower system according to a second aspect of the present invention includes the push-pull water distribution valve structure of the first aspect embodiment.

[0016] The shower system according to the present utility model has at least the above-mentioned beneficial effects since it includes the push-pull water distribution valve structure of the above embodiment, and will not be repeated here.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0032] Reference Figure 1 As shown, a push-pull water distribution valve structure provided in this embodiment of the utility model includes a valve body 100, a fixed cylinder 200, a piston 300, and a push button 400.

[0033] Reference Figure 3 and Figure 4 As shown, the valve body 100 has a generally cylindrical structure. The interior of the valve body 100 has a water distribution cavity 110. The outer peripheral wall of the valve body 100 is provided with a first outlet 120, an inlet 130 and a second outlet 140 that communicate with the water distribution cavity 110. The first outlet 120, the inlet 130 and the second outlet 140 are arranged sequentially along the axial direction of the valve body 100. The inlet 130 is located between the first outlet 120 and the second outlet 140. One end of the valve body 100 along its axial direction also has an installation port 150 that communicates with the water distribution cavity 110. The fixed cylinder 200 is a roughly cylindrical structure. The outer diameter of the fixed cylinder 200 is smaller than the inner diameter of the valve body 100. The fixed cylinder 200 is inserted into the water distribution cavity 110 through the mounting port 150. The outer peripheral wall of the fixed cylinder 200 and the inner wall of the water distribution cavity 110 are sealed together by a sealing ring. The outer peripheral wall of the fixed cylinder 200 is provided with a clearance hole 210 and a water passage 220 corresponding to the first water outlet 120. The lower end of the fixed cylinder 200 is provided with an opening 230, through which the piston 300 extends into the fixed cylinder 200. The piston 300 is located in the water distribution cavity 110 and can move axially along the valve body 100. The piston 300 includes a water distribution part 310, which is located between the first water outlet 120 and the second water outlet 140. The outer peripheral wall of the water distribution part 310 is provided with a water distribution sealing element 320, which can be a water distribution cup. The push button 400 is fixedly connected to the piston 300. By pushing and pulling the push button 400, the piston 300 can be driven to move axially. The push button 400 passes through the clearance hole 210, which extends axially to avoid the push button 400.

[0034] Reference Figure 3 and Figure 4 As shown, the piston 300 also includes a first water-sealing part 330 and a second water-sealing part 360. Along the axial direction of the piston 300, a water-distributing part 310 is located between the first water-sealing part 330 and the second water-sealing part 360. The outer peripheral wall of the first water-sealing part 330 is provided with a first water-sealing cup 340, which abuts against the inner peripheral wall of the fixed cylinder 200. The outer peripheral wall of the second water-sealing part 360 is provided with a second water-sealing cup 370, which abuts against the inner peripheral wall of the valve body 100. This achieves a water-sealing effect.

[0035] Reference Figure 3 and Figure 4 As shown, the piston 300 also includes a first shaft 390 and a second shaft 3010. The outer diameters of both the first shaft 390 and the second shaft 3010 are smaller than the outer diameter of the water distribution section 310. The first shaft 390 is connected between the first water sealing section 330 and the water distribution section 310, and the second shaft 3010 is connected between the second water sealing section 360 and the water distribution section 310. The function of the first shaft 390 and the second shaft 3010 is to allow water to flow through the piston 300.

[0036] When using the push-pull water distribution valve structure of this embodiment, as follows: Figure 4 As shown, by pushing the push button 400, the piston 300 is moved, causing the water-distributing seal 320 to abut against the inner circumferential wall of the fixed cylinder 200. At this time, the water-distributing seal 320 disconnects the inlet 130 from the first outlet 120, and the water can only flow through the inlet 130 to the second outlet 140, as shown by the arrow in the figure. Water is discharged from the second outlet 140. During this process, the pressure of the water flow acting on the water-distributing part 310 and the pressure of the water flow acting on the second sealing part 360 are exactly canceled out, so that the water-distributing part 310 can be maintained in this position, and the impact of water pressure on the piston 300 is small. Figure 7 As shown, by pushing the push button 400, the piston 300 is moved, causing the water-dividing seal 320 to be positioned at the inlet 130. The water-dividing seal 320 does not contact other components. There is a gap between the water-dividing part 310 and the valve body 100, and there is also a gap between the water-dividing part 310 and the fixed cylinder 200. Water can flow through these gaps into the first outlet 120 and the second outlet 140 respectively, as shown by the arrows in the figure. Water flows out from the first outlet 120 and the second outlet 140 simultaneously. At this time, the force of the water flow on both sides of the water-dividing part 310 will not cause the water-dividing part 310 to move axially, so the water-dividing part 310 is not easy to move automatically. The water pressure has a weak effect on the water-dividing part 310, allowing the water-dividing part 310 to remain in this position. Figure 8 As shown, by pushing the push button 400, the piston 300 is moved, causing the water distribution seal 320 to abut against the inner peripheral wall of the valve body 100. At this time, the water distribution seal 320 disconnects the inlet 130 from the second outlet 140, and the water can only flow through the inlet 130 to the first outlet 120, as shown by the arrow in the figure. Water is discharged from the first outlet 120. During this process, the pressure of the water flow acting on the water distribution part 310 and the pressure of the water flow acting on the first sealing part 330 are exactly canceled out, so that the water distribution part 310 can be kept in this position, and the impact of the water pressure on the piston 300 is small.

[0037] Overall, for the push-pull water distribution valve structure of this embodiment, the piston 300 inside is less affected by water pressure at any position. Therefore, the resistance to pushing the piston 300 is small, and the piston 300 is easier to move, which improves the user experience. Furthermore, since the piston 300 moves autonomously without being affected by water pressure, the water flow from both outlets can be kept constant, thereby improving the user experience.

[0038] Reference Figures 4 to 6 As shown, in some embodiments, the first sealing cup 340 has a first annular V-groove 340 facing the water distribution portion 310, and the second sealing cup 370 has a second annular V-groove 380 facing the water distribution portion 310. When water flows into the first annular V-groove 340 or the second annular V-groove 380, the water enters the V-groove and applies pressure evenly to the inner wall of the V-shaped sealing groove. This pressure forces the two lips of the sealing cup to expand outward, thus allowing them to fit more tightly against the sealed surface, improving the sealing effect. The greater the water pressure, the tighter the lips fit, and the better the sealing effect. This characteristic gives the V-shaped sealing cup good self-sealing performance; even if the initial pre-tightening force is insufficient or the sealing surface is slightly worn, the water pressure can compensate for this and maintain an effective seal.

[0039] Reference Figure 4 As shown, in some embodiments, the piston 300 is provided with a threaded hole 3020, and the outer peripheral wall of the push button 400 is provided with external threads. The push button 400 is threadedly connected to the threaded hole 3020 through the external threads. This allows the push button 400 to be installed after the piston 300 is installed, making assembly more convenient.

[0040] Reference Figure 3 and Figure 4 As shown, in some embodiments, the valve body 100 is provided with a mounting hole 3030 at the end opposite to the mounting port 150. The mounting hole 3030 is used for threaded connection with a fixing bolt, thereby fixing the valve body 100.

[0041] This utility model also provides a shower system, including the push-pull water diversion valve structure of the above embodiment. The shower system can be arranged in a bathroom or toilet. For example, the shower system includes an overhead shower and a hand shower, and the push-pull water diversion valve structure can be used to control the water flow from the overhead shower or the hand shower, or to control the water flow from both the overhead shower and the hand shower simultaneously.
