Description

Technical Field

[0001] This invention relates to the field of bathroom supplies technology, specifically to an easily adjustable shower screen. Background Technology

[0002] With the development of the sanitary ware industry and the improvement of people's living standards, shower screens, as a relatively modern sanitary ware facility, have become increasingly popular in households due to their smaller footprint and water-saving properties.

[0003] Currently, most families retain two bathrooms to meet the privacy and convenience needs of multi-person households. Under the current normal water pressure of urban water use, if two shower screens are used at the same time, the water pressure of a single shower screen will decrease, causing only 60-70% of the water outlets at the edge of the shower screen's top spray to drip instead of spraying, thus directly affecting the user's showering experience. To address the issue of reduced water pressure when multiple shower screens are used simultaneously, existing shower screens typically employ a Hall effect flow sensor in conjunction with a DC inverter pump and a self-heating device. When a decrease in flow is detected, the DC inverter pump is activated to pressurize the internal components and simultaneously improve heating efficiency, preventing issues like dripping water from the overhead shower and reduced temperature when multiple screens are in use. However, shower screens equipped with Hall effect flow sensors, DC inverter pumps, and self-heating devices are significantly more expensive and have higher operating costs than ordinary shower screens, making them unaffordable for most families with average incomes. Furthermore, existing ordinary shower screens cannot solve the problems of reduced water pressure and dripping water from the overhead shower when two screens are used simultaneously, thus greatly impacting the user experience.

[0004] Therefore, an easily adjustable shower screen is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an easily adjustable shower screen. By adjusting the height of the top spray nozzles and the number of nozzles according to changes in water pressure, this invention solves the problem that existing shower screens sometimes drip instead of spray when the water pressure drops, thus reducing the user experience. This invention is low-cost and can automatically adjust the water output of the top spray nozzles according to the water pressure, thereby improving the user experience.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An adjustable shower screen includes a shower housing, a mixing valve, a switching valve, a shower mechanism, a corrugated pipe, a water pressure mechanism, a power transmission mechanism, a top spray, an adjustment mechanism, and a reset mechanism. The shower mechanism is slidably mounted on the outside of the shower housing and extends into the shower housing. The water pressure mechanism is slidably mounted on the inner wall of the shower housing. The power transmission mechanism is mounted on the inner wall of the shower housing and extends between the shower mechanism and the water pressure mechanism. The top spray is mounted inside the shower mechanism. There are two corrugated pipes, one connecting the switching valve and the water pressure mechanism, and the other connecting the water pressure mechanism and the top spray. The adjustment mechanism is mounted inside the top spray and extends above the shower mechanism. The reset mechanism is mounted between the adjustment mechanism and the inner wall of the top spray. When the shower water pressure decreases, the water storage in the water pressure mechanism decreases, causing the weight of the water pressure mechanism to be lower than that of the shower mechanism. When the shower mechanism moves down, the power transmission mechanism drives the water pressure mechanism to move up, and at the same time, it drives the adjustment mechanism to close some of the water outlets of the top spray. When the water pressure recovers, the water pressure mechanism drives the shower mechanism to move up and opens the closed water outlets through the reset mechanism.

[0007] Preferably, the shower mechanism includes a lifting plate, a slider, a groove, a strip hole, a U-shaped plate, and a first rack. The slider is symmetrically fixedly connected to the side of the lifting plate near the shower housing. The groove is symmetrically opened on the side wall of the shower housing, and the strip hole is opened on the side wall of the shower housing. The slider on the side wall of the lifting plate is slidably connected inside the groove opened on the side wall of the shower housing. The U-shaped plate is fixedly connected to the side of the lifting plate near the shower housing, and the U-shaped plate extends through the strip hole into the shower housing. The first rack is fixedly connected to one end of the U-shaped plate that extends into the shower housing.

[0008] Preferably, the two slider sidewalls are symmetrically fixedly connected with rectangular blocks, and rectangular slots are symmetrically opened in the two slide grooves. The two rectangular blocks of the slider sidewalls are respectively slidably connected in the two rectangular slots opened in the slide grooves.

[0009] Preferably, the water pressure mechanism includes a water tank, a toothed groove, a second toothed rack, a vertical plate, and a vertical slot. The two vertical plates are symmetrically fixedly connected to the side of the water tank near the inner wall of the shower housing. The vertical slots are symmetrically opened on the inner wall of the shower housing. The two vertical plates are slidably connected in the two vertical slots respectively. The toothed groove is opened on the side of the water tank away from the vertical plate. The second toothed rack is fixedly connected inside the toothed groove.

[0010] Preferably, the side walls of the two vertical plates are symmetrically fixedly connected with limiting strips, and the inner walls of the two vertical grooves are symmetrically provided with limiting grooves. The two limiting strips are slidably connected inside the two limiting grooves respectively.

[0011] Preferably, the power transmission mechanism includes an L-shaped plate and a gear. The two L-shaped plates are symmetrically fixedly connected to the inner wall of the shower housing and located on both sides of the water tank. The ends of the two L-shaped plates extend into the tooth grooves respectively, and the gear is rotatably connected between the ends of the two L-shaped plates.

[0012] Preferably, the first rack is located between the water tank and the inner wall of the shower housing, and the gears mesh with the first rack and the second rack respectively.

[0013] Preferably, the adjustment mechanism includes an arc-shaped plate, a pull rope, a sliding plate, a sliding block, and a strip groove. One end of the arc-shaped plate is fixedly connected to the top surface of the shower housing and extends above the lifting plate. One end of the pull rope is fixedly connected to the bottom of the arc-shaped plate and extends into the top spray. The two sliding plates slide against the lower end of the inner wall of the top spray. The part of the pull rope extending into the top spray has two ends, which are fixedly connected to the top surfaces of the two sliding plates respectively. The sliding blocks are symmetrically fixedly connected to the bottom of the sliding plates. The strip grooves are symmetrically opened at the lower end of the inside of the top spray, and the sliding blocks slide in the strip grooves respectively.

[0014] Preferably, the reset mechanism includes a fixed plate, a tension spring, and a connecting plate. The fixed plate and the connecting plate are respectively fixedly connected to the top surface of the sliding plate and the inner wall of the top sprayer, and the two ends of the tension spring are respectively fixedly connected to the side walls of the fixed plate and the connecting plate.

[0015] Preferably, the connecting plate is symmetrically fixedly connected to the side of the fixed plate, and the two limiting rods slide through the fixed plate respectively.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention enables the water pressure mechanism to reduce its weight when two or more shower screens are used simultaneously, causing a drop in water pressure, or for other reasons. When the weight of the water pressure mechanism is lower than that of the shower mechanism, the shower mechanism moves downward and drives the water pressure mechanism upward through the power transmission mechanism. As the shower mechanism moves downward, the adjustment mechanism closes some of the water outlets in the overhead shower, preventing the overhead shower from dripping without spraying. At the same time, reducing the height of the shower mechanism can prevent the water temperature from dropping due to the reduced number of water jets and insufficient contact between cold air and the water jets, thus effectively ensuring the user experience.

[0017] 2. The water pressure mechanism uses a sliding water tank between the switch valve and the top spray. The weight is adjusted by the pressure and water volume in the tank. The height of the shower mechanism is adjusted according to the weight of the water tank and the power transmission mechanism. The power transmission is achieved through a single gear and two racks. Its structure is simple and easy to install, thus ensuring its low manufacturing cost.

[0018] 3. When the shower unit moves downward due to reduced water pressure, the reset mechanism closes some of the water outlets in the overhead shower and stretches the reset mechanism through the adjustment mechanism. When the water pressure is restored and the shower unit resets upward, the reset mechanism will pull the adjustment mechanism to reset and reopen the blocked water outlets. This prevents the water outlets from dripping and not spraying when the water pressure is low. When the water pressure is restored, the original number of water outlets is restored simultaneously.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 8This invention provides an easily adjustable shower screen, the technical solution of which is as follows: As one embodiment of the present invention, refer to Figures 1 to 3 An easily adjustable shower screen includes a shower housing 1, a mixing valve 2, and a switch valve 3. The mixing valve 2 and the switch valve 3 are fixedly connected inside the shower housing 1. The bottom of the shower housing 1 is the inlet for the hot and cold water pipes, which are preferentially connected to the mixing valve 2. The outlet of the mixing valve 2 is connected to the switch valve 3. A one-way valve connects the mixing valve 2 and the switch valve 3. The top outlet of the switch valve 3 is connected to a corrugated pipe 5. The outlet on one side of the switch valve 3 is connected to the shower head and extends to the outside of the shower housing 1. The side wall of the shower housing 1 is mounted with a stainless steel panel, and a sealing strip is provided between the stainless steel panel and the shower housing 1. The stainless steel panel is bolted to the shower housing 1. A steel panel is installed on the surface of the shower housing 1 to further improve the sealing effect. It also includes a shower mechanism 4, a corrugated pipe 5, a water pressure mechanism 6, a power transmission mechanism 7, a top spray 8, an adjustment mechanism 9, and a reset mechanism 10. The corrugated pipe 5 can be, but is not limited to, a stainless steel corrugated pipe 5. Stainless steel corrugated pipe 5 has high and low temperature resistance (-20℃ to 150℃), is compatible with hot water pipe connections, and is corrosion-resistant and rust-resistant, able to withstand the humid environment of the bathroom for a long time. The pipe wall is made of spirally welded thin stainless steel sheets, which is not easily deformed after bending and can be repeatedly bent to adjust its direction. This effectively adapts to the water pressure mechanism 6 moving up and down with changes in water pressure, and is constantly connected to the corrugated pipe 5. Thanks to the one-way valve, the backflow of water in the water pressure mechanism 6 is prevented when the shower screen is closed, thus avoiding a decrease in the water storage capacity of the water pressure mechanism 6 and preventing the shower mechanism 4 from moving downwards when the shower screen is closed. The shower mechanism 4 is slidably installed on the outside of the shower housing 1 and extends into the inside of the shower housing 1. The water pressure mechanism 6 is slidably installed on the inner wall of the shower housing 1. The power transmission mechanism 7 is installed on the inner wall of the shower housing 1 and extends between the shower mechanism 4 and the water pressure mechanism 6. The overhead shower 8 is installed inside the shower mechanism 4. There are two bellows 5, one connecting the switch valve 3 and the water pressure mechanism 6, and the other connecting the water pressure mechanism 6 and the overhead shower 8. A flexible hose is installed on the side wall of the overhead shower 8. The shower housing 1 has a rectangular hole on its side wall. The hose of the top spray 8 extends through the rectangular hole into the shower housing 1 and is connected to the bellows 5. The adjustment mechanism 9 is installed inside the top spray 8 and extends above the shower mechanism 4. The reset mechanism 10 is installed between the adjustment mechanism 9 and the inner wall of the top spray 8. When the shower water pressure decreases, the water storage in the water pressure mechanism 6 decreases, causing the weight of the water pressure mechanism 6 to be lower than that of the shower mechanism 4. When the shower mechanism 4 moves down, the water pressure mechanism 6 moves up through the power transmission mechanism 7, and at the same time, the adjustment mechanism 9 closes some of the water outlets of the top spray 8. When the water pressure is restored, the water pressure mechanism 6 moves the shower mechanism 4 up and opens the closed water outlets through the reset mechanism 10.

[0023] When using the overhead shower 8, water first enters the water tank 601 in the water pressure mechanism 6, and then flows into the overhead shower 8 through the corrugated pipe 5 on the other side of the water tank 601. Since the water tank 601 is sealed, the pressure inside the water tank 601 increases when the water pressure rises, and the water volume in the water tank 601 also increases. When the water volume in the water tank 601 increases and its weight exceeds that of the shower mechanism 4, the water tank 601 in the water pressure mechanism 6 moves downwards and drives the shower mechanism 4 upwards through the power transmission mechanism 7. The adjusting mechanism 9 and the reset mechanism 10 then open all the water outlets of the overhead shower 8. When the water pressure rises to normal, the water output of the shower mechanism 4 is optimal, and the height of the shower mechanism 4 can also rise to the optimal position simultaneously, effectively improving the user's showering experience. When two shower screens are used simultaneously, causing a decrease in water pressure, or for other reasons, the water pressure decreases, and the pressure inside the water tank 601 in the water pressure mechanism 6 also decreases, resulting in a decrease in its internal water volume and weight. When the weight of the water tank 601 is lower than that of the shower mechanism 4, the shower mechanism 4 moves downward and, under the action of the power transmission mechanism 7, drives the water pressure mechanism 6 to move upward. At the same time as the shower mechanism 4 moves downward, the adjustment mechanism 9 simultaneously closes the outer water outlets of the top spray 8, reducing the number of water outlets. By reducing the number of water outlets, the normal water flow of some water outlets is ensured, avoiding the situation where the top spray 8 drips but does not spray due to reduced water pressure. At the same time as the number of water outlets of the top spray 8 decreases, the height of the shower mechanism 4 also decreases. When the number of water outlets of the top spray 8 decreases, the water jets of the top spray 8 become sparse, so cold air can enter between the clustered water jets. Excessive contact between the clustered water jets and cold air will accelerate the cooling speed of the water jets, resulting in a drop in water temperature when the water jets fall on the human body surface, directly affecting the user's showering experience. By lowering the height of the top spray 8, the time for the water jets to be cooled by the air is reduced, thereby avoiding excessive temperature drop when the water jets come into contact with the human body.

[0024] As one embodiment of the present invention, refer to Figure 3 and Figure 6The shower mechanism 4 includes a lifting plate 401, a slider 402, a slide groove 403, a slotted hole 404, a U-shaped plate 405, and a first rack 406. The slider 402 is symmetrically fixedly connected to the side of the lifting plate 401 near the shower housing 1, and the slide groove 403 is symmetrically opened on the side wall of the shower housing 1. The slotted hole 404 is opened on the side wall of the shower housing 1. The slider 402 on the side wall of the lifting plate 401 is slidably connected to the inside of the slide groove 403 opened on the side wall of the shower housing 1. The sidewall of slider 402 slides against the inside of the slide groove 403, and lubricating grease can be added to the slide groove 403 to further reduce the friction between slider 402 and slide groove 403. U-shaped plate 405 is fixedly connected to the side of lifting plate 401 near shower housing 1, and U-shaped plate 405 extends through strip hole 404 into shower housing 1. First rack 406 is fixedly connected to one end of U-shaped plate 405 extending into shower housing 1. The first rack 406 at the bottom of U-shaped plate 405 extends... The first rack 406 extends to one side of the water pressure mechanism 6 but is not connected to it. At the same time, the teeth of the first rack 406 are close to the water pressure mechanism 6. A rubber gasket is fixedly connected to the side of the lifting plate 401 close to the shower housing 1. The sealing gasket is used to improve the sealing effect between the lifting plate 401 and the shower housing 1. The strip hole 404 is always in contact with the side wall of the sealing gasket. No matter how the lifting plate 401 rises or falls, the strip hole 404 will not be exposed, thus preventing water vapor from entering the shower housing 1 through the strip hole 404. Rectangular blocks are symmetrically fixedly connected to the side walls of the two sliders 402. Rectangular grooves are symmetrically opened in the two slide grooves 403. The two rectangular blocks on the side walls of the sliders 402 are slidably connected to the two rectangular grooves opened in the slide grooves 403. Thanks to the setting of the two rectangular blocks and the rectangular grooves, the rectangular blocks are slidably connected in the rectangular grooves. The rectangular blocks can effectively limit the sliding direction of the sliders 402 and the lifting plate 401, preventing the sliders 402 from falling out of the slide grooves 403.

[0025] As one embodiment of the present invention, refer to Figures 3 to 5The water pressure mechanism 6 includes a water tank 601, a toothed groove 602, a second toothed rack 603, vertical plates 604, and vertical slots 606. Two vertical plates 604 are symmetrically fixedly connected to the water tank 601 on the side near the inner wall of the shower housing 1. Vertical slots 606 are symmetrically formed on the inner wall of the shower housing 1. The two vertical plates 604 are slidably connected within the two vertical slots 606. The sliding connection of the vertical plates 604 within the vertical slots 606 effectively limits the sliding direction of the water tank 601. Lubricant needs to be added to the vertical slots 606 to reduce the friction between the vertical plates 604 and the vertical slots 606. The toothed groove 602 is formed in the water tank 601 away from the vertical plates 601. On one side of 04, the second rack 603 is fixedly connected inside the toothed groove 602. One end of each of the two corrugated pipes 5 is connected to the lower side wall of the water tank 601. The side walls of the two vertical plates 604 are symmetrically fixedly connected with limiting strips 605. The inner walls of the two vertical grooves 606 are symmetrically provided with limiting grooves. The two limiting strips 605 are slidably connected inside the two limiting grooves. Thanks to the setting of the two limiting strips 605, the limiting strips 605 are slidably connected inside the limiting grooves, which can effectively prevent the vertical strips from detaching from the vertical grooves 606, and at the same time prevent the water tank 601 from falling. It can also further improve the stability of the water tank 601 when sliding up and down.

[0026] As one embodiment of the present invention, refer to Figure 4The power transmission mechanism 7 includes an L-shaped plate 701 and a gear 702. Two L-shaped plates 701 are symmetrically fixed to the inner wall of the shower housing 1 and located on both sides of the water tank 601. The ends of the two L-shaped plates 701 extend into the toothed grooves 602. The gear 702 is rotatably connected between the ends of the two L-shaped plates 701. A first rack 406 is located between the water tank 601 and the inner wall of the shower housing 1, and the gear 702 meshes with the first rack 406 and the second rack 603 respectively. The gear 702 is mounted on one side of the water tank 601 via the two L-shaped plates 701, and the two L-shaped plates 701 do not contact the water tank 601. When the water pressure increases, causing the water pressure and water volume in the water tank 601 to increase, and the weight of the water tank 601 exceeds the weight of the shower mechanism 4, the water tank 601 moves downward, simultaneously causing the second rack 603 on its side wall to move downward. The second rack 603 drives the gear 702 to rotate. As the gear 702 rotates, it pushes the first rack 406 and the shower mechanism 4 to move upward. Similarly, when the water pressure drops and the weight of the water tank 601 decreases and becomes lower than the weight of the shower mechanism 4, the shower mechanism 4 drives the first rack 406 to move downward. The first rack 406 drives the gear 702 to rotate. The rotation of the gear 702 drives the water tank 601 to rise. In this way, the shower mechanism 4 can be moved up and down by the change in water pressure, so that the shower mechanism 4 can adjust its height according to the change in water pressure, thus avoiding affecting the user experience. At the same time, the shower screen can realize the adjustment of the height of the top spray 8 with the change of water pressure by only the sliding water tank 601, the first rack 406 and the second rack 603 in conjunction with the power transmission mechanism 7. All the required parts are common in the market, so it has the advantages of simple assembly and low cost.

[0027] As one embodiment of the present invention, refer to Figure 6 and Figure 7The adjustment mechanism 9 includes an arc-shaped plate 901, a pull rope 902, a sliding plate 903, a sliding block 904, and a strip groove 905. One end of the arc-shaped plate 901 is fixedly connected to the top surface of the shower housing 1 and extends above the lifting plate 401. One end of the pull rope 902 is fixedly connected to the bottom of the arc-shaped plate 901 and extends into the top spray 8. The pull rope 902 and the top spray 8 are provided with a sliding seal to prevent water leakage from between the top spray 8 and the pull rope 902. The pull rope 902 can be made of, but is not limited to, silicone-coated steel wire. It exhibits excellent high and low temperature resistance and flexibility, making it suitable for sealing and bending with the top sprayer 8. Two sliding plates 903 slide and adhere to the lower inner wall of the top sprayer 8. A sealing gasket is fixedly bonded to the bottom of each sliding plate 903, directly sliding and sealing against the lower inner wall of the top sprayer 8. This allows the covering water outlet to be closed when the sliding plate 903 slides above it. The pull rope 902 extends into the top sprayer 8, ending at two ends, which are respectively connected to two… The top surface of the sliding plate 903 is fixedly connected, and the two ends of the pull rope 902 will not move to the outside of the top spray 8. The pulling stroke of the pull rope 902 is sufficient to ensure that the sliding plate 903 is pulled to seal and cover part of the water outlet of the top spray 8, thereby ensuring the sealing effect between the pull rope 902 and the top spray 8. The sliding blocks 904 are symmetrically fixedly connected to the bottom of the sliding plate 903, and the strip grooves 905 are symmetrically opened inside the lower end of the top spray 8. The sliding blocks 904 slide in the strip grooves 905 respectively. Within 5, when the lifting plate 401 in the spray mechanism moves downward due to the drop in water pressure, it can pull the pull rope 902 upward. Through the two ends of the pull rope 902, the two sliding plates 903 are pulled synchronously, thus blocking the water outlets of the top spray 8 simultaneously. At the same time, the lifting plate 401 drives the top spray 8 to descend, reducing the number of water outlets of the top spray 8. This can prevent the situation where the water outlets of the top spray 8 drip and do not spray due to the excessive number of water outlets caused by the drop in water pressure, thereby further improving the user experience.

[0028] As one embodiment of the present invention, refer to Figure 7 and Figure 8The reset mechanism 10 includes a fixed plate 1001, a tension spring 1002, and a connecting plate 1003. The fixed plate 1001 and the connecting plate 1003 are respectively fixedly connected to the top surface of the sliding plate 903 and the inner wall of the top spray 8. Both the fixed plate 1001 and the connecting plate 1003 are horizontally and vertically arranged. The two ends of the tension spring 1002 are respectively fixedly connected to the side walls of the fixed plate 1001 and the connecting plate 1003. When the lifting plate 401 descends due to a decrease in water pressure, the pull rope 902 in the adjusting mechanism 9 is pulled upwards, and the pull rope 902 drives the two sliding plates 903 to move closer to each other, closing some of the water outlets of the top spray 8. While the sliding plates 903 are moving closer to each other, This causes the fixed plate 1001 to move, pulling the tension spring 1002. Similarly, when the lifting plate 401 moves upward, the tension spring 1002 loses its tension and resets. The tension spring 1002 pulls the sliding plate 903 to reset and move, thereby opening the closed water outlet. The connecting plate 1003 is symmetrically fixed with limit rods 1004 on the side near the fixed plate 1001. The two limit rods 1004 slide through the fixed plate 1001 respectively. Thanks to the setting of the two limit rods 1004, the sliding direction of the fixed plate 1001 is limited by the two limit rods 1004 when the fixed plate 1001 moves, further preventing the fixed plate 1001 from deviating when sliding.

[0029] Working principle: During use, hot and cold water enter the mixing valve 2 through the bottom of the shower screen. After opening the mixing valve 2, the water flows upward through the switch valve 3. The switch valve 3 controls the alternation of use between the overhead spray 8 and the shower head. When the overhead spray 8 is used, the water flows through the corrugated pipe 5 into the water pressure mechanism 6, causing water to accumulate in the water pressure mechanism 6. Subsequently, the water enters the overhead spray 8 through another corrugated pipe 5 and sprays out. When the water pressure is lower than the normal value, the water pressure in the water pressure mechanism 6 decreases accordingly. Simultaneously, the water storage capacity in the water pressure mechanism 6 decreases, and the weight decreases. When the weight of the water pressure mechanism 6 is less than the weight of the shower mechanism 4, the shower mechanism 4 will move downward and push the water pressure mechanism 6 upward through the power transmission mechanism 7. As the shower mechanism 4 moves downward, it pulls the pull rope 902 in the adjustment mechanism 9 upward, thereby causing the adjustment mechanism 9 to seal and close some of the water outlets in the overhead spray 8. If the water pressure continues to decrease, the shower mechanism... The greater the downward stroke of shower mechanism 4, the more water outlets are closed by adjustment mechanism 9. This allows the shower mechanism 4 to move downward when the water pressure decreases, preventing the temperature of the water jet from the top spray 8 from dropping. It also closes some water outlets to prevent dripping instead of spraying, thus improving the user experience. When the water pressure returns to normal, the water pressure in water pressure mechanism 6 increases, and its internal water storage capacity also increases. When the weight of water pressure mechanism 6 is greater than the weight of shower mechanism 4, water pressure mechanism 6 moves downward and pushes shower mechanism 4 upward under the action of power transmission mechanism 7. As shower mechanism 4 moves upward, the pull rope 902 in adjustment mechanism 9 loses its upward pull. At this time, the reset mechanism 10 pulls adjustment mechanism 9 to reset and reopens some of the closed water outlets. This allows the height of shower mechanism 4 and the number of water outlets in top spray 8 to be adjusted according to changes in water pressure, thus ensuring the user experience. Specifically, two corrugated pipes 5 are connected to both sides of the water tank 601 in the water pressure mechanism 6. When water enters the water tank 601 through one of the corrugated pipes 5, the pressure in the water tank 601 is increased, and at the same time, some water is retained in the water tank 601, thereby increasing the weight of the water tank 601. The pressure and water storage in the water tank 601 change according to the water pressure in the corrugated pipe 5. When the water pressure in the corrugated pipe 5 increases, the pressure and water storage in the water tank 601 increase accordingly. If the pressure in the corrugated pipe 5 decreases, the pressure in the water tank 601 decreases and the water storage decreases accordingly. This achieves the effect of changing the weight of the water tank 601 through water pressure, so as to facilitate the raising or lowering of the shower mechanism 4 according to the water pressure. Specifically, since the arc plate 901 in the adjustment mechanism 9 is fixedly installed on the top surface of the shower housing 1, when the shower mechanism 4 moves downward due to the decrease in water pressure, it will pull the pull rope 902 upward. At the same time as the pull rope 902 is pulled upward, it will drive the two sliding plates 903 in the top spray 8 to move closer to each other and close some of the water outlets of the top spray 8, thereby ensuring the spraying effect of the remaining water outlets and avoiding the situation of dripping without spraying, which will affect the user experience. At the same time as the sliding plates 903 move closer to each other, they will stretch the tension spring 1002 in the reset mechanism 10. When the shower mechanism 4 moves upward and the pull rope 902 loses its upward pulling force, the tension spring 1002 in the reset mechanism 10 will pull the two sliding plates 903 to reset and reopen the part of the water outlets that were blocked.
