Description

Technical Field

[0001] This invention relates to the field of bathroom technology, and in particular to a lifting sliding seat structure and shower device that counteracts the effect of water pressure. Background Technology

[0002] Currently, most height-adjustable shower devices on the market use a threaded locking structure. To adjust the shower head height, the nut or screw must be loosened and then tightened again once the desired height is achieved. When family members have significant height differences, adjustment must be made every time the shower is used to achieve the best shower effect. This is time-consuming, inconvenient, and prevents height adjustment while the water is running.

[0003] Among existing patents, the applicant filed a Chinese patent application on August 1, 2024, with application number 202411050942.0, disclosing an adjustable height shower device, including an outer pipe, an inner pipe, a drain pipe connector, a middle water pipe connector, a gravity balance mechanism, a telescopic water pipe, a water inlet connector, a connecting water pipe, a horizontal pipe, a horizontal water pipe assembly, a wall base, and a bushing. The two ends of the gravity balance mechanism are rotatably connected to the middle water pipe connector and the drain pipe connector, respectively. The bushing is fitted outside the inner pipe. There are swing gaps between the inner wall of the bushing and the outer wall of the inner pipe, and between the inner wall of the outer pipe and the outer wall of the inner pipe, allowing the inner pipe to swing. An elastic friction pad is provided on the back of the inner pipe, which is used to abut against the inner wall of the outer pipe. A lifting groove is opened in the middle of the outer pipe. A handle is connected to the inner pipe. The handle extends out of the outer pipe through the lifting groove and is slidably set in the lifting groove. While the patent document describes a simple method to adjust the shower head height by pulling the handle, the upward force of the water pressure causes the shower head to lurch upwards. Therefore, height adjustment is only possible when the water supply is off, not while the water is running or during use. Furthermore, the upward force of the water pressure makes the height adjustment unstable. Additionally, when the water pressure is unstable, the magnitude of the upward force on the shower head changes, making it difficult for the shower head to remain stably at the desired height. Therefore, the shortcomings are significant, and a solution is urgently needed. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a lifting sliding seat structure and a shower device that counteracts the effect of water pressure.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A lifting sliding seat structure for counteracting water pressure includes a vertical rod, a fixed seat mounted on the vertical rod, a slider slidably connected to the vertical rod and located above the fixed seat, a telescopic water-passing structure connecting the fixed seat and the slider, a sliding tube slidably connected to the vertical rod and located above the slider, and a support mechanism mounted on the vertical rod. The support mechanism includes a fixed cylinder mounted on the fixed seat, a piston slidably and sealed to the bore wall of the fixed cylinder, a sealing cover covering the top port of the fixed cylinder, and a movable tube mounted between the piston and the slider and slidably passing through the sealing cover. The piston can divide the inner hole of the fixed cylinder into an upper chamber and a lower chamber. The slider has a three-way water channel, the three ports of which are respectively connected to the outlet of the telescopic water-passing structure, the inlet of the sliding tube, and the top port of the movable tube. A water passage hole is opened on the bottom side wall of the movable tube, and the inner hole of the movable tube is connected to the upper chamber through the water passage hole.

[0007] Furthermore, the side wall of the upright is recessed with a lifting groove, the fixed seat is installed in the lifting groove, the slider is slidably connected to the inner wall of the lifting groove, the sliding tube is slidably connected to the inner wall of the lifting groove, and the telescopic water passage structure, the movable tube and the fixed cylinder are all located in the lifting groove.

[0008] Furthermore, the fixed base is provided with a water inlet connection hole, and the water inlet of the telescopic water passage structure is connected to the water inlet connection hole.

[0009] Furthermore, the telescopic water passage structure includes a fixed water pipe installed on a fixed base and a movable water pipe that is sealed and telescopically connected to the fixed water pipe. The top end of the movable water pipe is installed on a slider and connected to the water inlet port of the three-way water passage.

[0010] Furthermore, the top end of the movable water pipe is installed in the inlet port of the three-way water channel via a retaining ring. A first sealing ring is provided between the outer wall of the movable water pipe and the inner wall of the inlet port of the three-way water channel. The outer wall of the bottom end of the movable water pipe is slidably connected to the hole wall of the fixed water pipe via a second sealing ring.

[0011] Furthermore, the top of the movable tube is installed in the side outlet port of the three-way water channel via a snap ring, and a third sealing ring is provided between the outer wall of the movable tube and the inner wall of the side outlet port of the three-way water channel.

[0012] Furthermore, a first sealing ring is embedded in the inner hole of the sealing cap, and the movable tube is slidably connected to the sealing cap via the first sealing ring.

[0013] Furthermore, a second sealing ring is embedded in the peripheral wall of the piston, and the piston is slidably connected to the bore wall of the fixed cylinder through the second sealing ring.

[0014] Furthermore, the upright is equipped with a positioning block, the bottom surface of which abuts against the top surface of the sealing cover. The positioning block has two positioning holes, the movable pipe slides through one positioning hole, and the telescopic water passage structure passes through the other positioning hole.

[0015] The present invention also provides a shower device, including a shower head and the above-mentioned lifting sliding seat structure for counteracting water pressure, wherein the shower head is mounted on a sliding pipe.

[0016] The beneficial effects of this invention are as follows: In practical applications, the upright is fixed to an external structure such as a wall. The support mechanism supports the slider, water pipe, and sliding tube, allowing them to remain at the required height of the upright. Water is supplied to the water pipe, sliding tube, and shower head via the telescopic water passage and the three-way water channel. At this time, the water pressure applies an upward force F1 to the shower head. Simultaneously, water also enters the movable tube through the three-way water channel. The water in the movable tube enters the upper cavity through the water passage, causing the water pressure to apply a downward force to the top surface of the piston. F2, according to the liquid pressure formula F=PS, where F represents the pressure of the liquid on the contact area, P is the liquid pressure, and S is the contact area. When S is the same, F1=F2. Since F1 and F2 are in opposite directions, F1 and F2 cancel each other out, thus canceling the force of the water pressure. Therefore, when adjusting the height of the shower head during use, it will not be affected by the force of the water pressure. The height can be adjusted under the condition of water flow, making the height adjustment of the sliding pipe and the shower head more convenient, easy, stable and accurate. The shower head will not move upward under the action of water pressure. Attached Figure Description

[0026] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0027] like Figures 1 to 7 As shown, the present invention provides a lifting sliding seat structure for counteracting water pressure, comprising a vertical rod 1, a fixed seat 2 mounted on the vertical rod 1, a slider 3 slidably connected to the vertical rod 1 and located above the fixed seat 2, a telescopic water-passing structure 4 connecting the fixed seat 2 and the slider 3, a sliding tube 5 slidably connected to the vertical rod 1 and located above the slider 3, a water-passing pipe 27 connecting the sliding tube 5 and the slider 3, and a support mechanism 6 mounted on the vertical rod 1 for providing support force. The support mechanism 6 includes a fixed cylinder 7 mounted on the fixed seat 2, a piston 8 slidably and sealed to the hole wall of the fixed cylinder 7, and a cover on the fixed cylinder. The top port of the fixed cylinder 7 has a sealing cap 9 and a movable tube 10 installed between the piston 8 and the slider 3 and sliding through the sealing cap 9 in a sealed manner. The piston 8 can divide the inner hole of the fixed cylinder 7 into an upper cavity 11 and a lower cavity 12. The slider 3 has a three-way water channel 13. The three ports of the three-way water channel 13 are respectively connected to the outlet of the telescopic water passage structure 4, the inlet of the water passage pipe 27 and the top port of the movable tube 10. The bottom side wall of the movable tube 10 has a water passage hole 14. The inner hole of the movable tube 10 is connected to the upper cavity 11 through the water passage hole 14. The inlet of the sliding tube 5 is connected to one port of the three-way water channel 13 through the water passage pipe 27.

[0028] The present invention also provides a shower device, including a shower head and the above-mentioned lifting sliding seat structure for counteracting water pressure, wherein the shower head is installed on the sliding pipe 5.

[0029] In practical applications, the upright 1 is fixedly installed on an external structure such as a wall. The support mechanism 6 supports the slider 3, water pipe 27, and sliding pipe 5, so that the slider 3, water pipe 27, and sliding pipe 5 remain at the required height of the upright 1. Water is supplied to the water pipe 27, sliding pipe 5, and shower head through the telescopic water passage 4 and the three-way water channel 13. At this time, the water pressure will exert an upward force F1 on the shower head. At the same time, the water will also enter the movable pipe 10 through the three-way water channel 13. The water in the movable pipe 10 will enter the upper cavity 11 through the water passage 14, so that the water pressure will be directed towards the top surface of the piston 8. Applying a downward force F2, according to the liquid pressure formula F = PS, where F represents the pressure of the liquid on the contact area, P is the liquid pressure, and S is the contact area, when S is the same, F1 = F2. Since F1 and F2 are in opposite directions, they cancel each other out, thus canceling the force of the water pressure. Therefore, the height adjustment of the shower head during use is not affected by the water pressure, allowing for height adjustment even when water is flowing. This makes height adjustment of the sliding tube 5 and the shower head more convenient, easy, stable, and accurate, preventing the shower head from surging upwards under water pressure. To adjust the shower head height, simply apply an upward or downward force to the slider 3, sliding tube 5, or the shower head.

The design of the lifting groove 15 makes the structure of the upright 1, the water pipe 27, the telescopic water-passing structure 4, the movable tube 10, and the fixed cylinder 7 compact, the lifting and sliding of the slider 3 is more stable and smooth, and it also provides a certain degree of protection for the water pipe 27, the telescopic water-passing structure 4, the movable tube 10, and the fixed cylinder 7.

[0031] In this embodiment, the fixed base 2 is provided with a water inlet connection hole 16, and the water inlet of the telescopic water-passing structure 4 is connected to the water inlet connection hole 16. In practical applications, the water supply pipe is installed on the fixed base 2 and connected to the water inlet connection hole 16, and the water supply pipe supplies water to the telescopic water-passing structure 4 through the water inlet connection hole 16.

[0032] In this embodiment, the telescopic water passage structure 4 includes a fixed water pipe 17 installed on the fixed base 2 and a movable water pipe 18 that is sealed and telescopically connected to the fixed water pipe 17. The top end of the movable water pipe 18 is installed on the slider 3 and communicates with the water inlet port of the three-way water channel 13. In practical applications, the fixed water pipe 17 and the movable water pipe 18 can telescopically slide, ensuring that the telescopic water passage structure 4 can pass water normally without affecting the lifting and lowering sliding of the slider 3. Moreover, the fixed water pipe 17 and the movable water pipe 18 guide each other, making the lifting and lowering sliding of the slider 3 more stable.

[0033] In this embodiment, the top end of the movable water pipe 18 is installed in the inlet port of the three-way water channel 13 via a retaining ring 19. A first sealing ring 20 is provided between the outer wall of the movable water pipe 18 and the inner wall of the inlet port of the three-way water channel 13. The bottom outer wall of the movable water pipe 18 is slidably connected to the hole wall of the fixed water pipe 17 via a second sealing ring 21. This structural design ensures good sealing between the movable water pipe 18 and the three-way water channel 13, and good sealing between the movable water pipe 18 and the fixed water pipe 17, preventing water leakage.

[0034] In this embodiment, the top end of the movable pipe 10 is installed inside the side outlet port of the three-way water channel 13 via a retaining ring 22, and a third sealing ring 23 is provided between the outer wall of the movable pipe 10 and the inner wall of the side outlet port of the three-way water channel 13. This structural design ensures good sealing between the movable pipe 10 and the side outlet port of the three-way water channel 13, preventing water leakage.

[0035] In this embodiment, a first sealing ring 24 is embedded in the inner hole of the sealing cap 9, and the movable tube 10 is slidably connected to the sealing cap 9 via the first sealing ring 24. This structural design ensures good sealing between the movable tube 10 and the sealing cap 9, preventing water leakage.

[0036] In this embodiment, a second sealing ring 25 is embedded in the peripheral wall of the piston 8, and the piston 8 is slidably connected to the bore wall of the fixed cylinder 7 via the second sealing ring 25.

The positioning block 26 is secured to the upright 1 with screws, and the bottom surface of the positioning block 26 abuts against the top surface of the sealing cover 9. The positioning block 26 has two positioning holes, through which the movable tube 10 slides and through one positioning hole, and through which the telescopic water-passing structure 4 passes. This structural design allows the positioning block 26 to not only press down on the sealing cover 9 to prevent it from detaching from the fixed cylinder 7, but also to position the movable tube 10 and the telescopic water-passing structure 4, ensuring their stability within the lifting slide 15.

[0038] Specifically, the bottom end of the fixed water pipe 17 is installed in the water inlet connection hole 16 of the fixing base 2 via the insert 28, and a fourth sealing ring 29 is provided between the outer wall of the fixed water pipe 17 and the wall of the water inlet connection hole 16.
