Description

Technical Field

[0001] The utility model relates to the technical field of bathroom water tank accessories, in particular to a diversion pressure relief water replenisher. Background Art

[0002] During routine toilet maintenance, maintaining an appropriate water seal height is essential not only for isolating odors and ensuring bathroom air quality, but also for maintaining a fresh and pleasant bathroom environment. After a flush, if the water seal height drops, the water replenishment system, drawing water from the tank, slowly and evenly directs an appropriate amount of water around the toilet seat, precisely replenishing the water seal and ensuring the water level remains stable above the established standard. This effectively prevents the escape of unpleasant odors and maintains a fresh and pleasant bathroom environment.

[0003] However, when existing water replenishment systems are replenishing, a large amount of water flows rapidly into the toilet seat area. Due to the narrow pipes and high water flow rate, a high-pressure area is easily formed between the water replenisher and the water inlet valve. This high-pressure state not only increases the load on the water replenishment system, but can also cause a sharp increase in pressure within the water replenishment pipe, which can cause the water replenishment pipe to burst or fall off. Utility Model Content

[0004] The purpose of the utility model is to provide a diversion pressure relief water make-up device, which realizes dual regulation of water replenishment amount and pressure relief amount by rotating the rotating part, ensuring that effective pressure relief operation can be performed simultaneously during the water replenishment process, solving the problem that high pressure maintenance is easily formed between the water inlet valve and the water make-up device during high-flow water replenishment in traditional water make-up systems, and effectively preventing safety hazards such as the water make-up pipe bursting or falling off caused by this.

[0005] To achieve the above-mentioned purpose, the solution of the present invention is: a diverter pressure relief water replenisher, comprising a water replenishing body, wherein the water replenishing body is provided with a water inlet chamber, a water replenishing chamber and a pressure relief chamber, wherein the water inlet chamber is connected to the water replenishing chamber through a water replenishing water channel, and the water inlet chamber is connected to the pressure relief chamber through a pressure relief water channel;

[0006] A rotating member is provided in the water inlet chamber, and an adjustment opening communicating with the water inlet chamber is provided on the side wall of the rotating member. The rotating member rotates so that the overlapping area of the adjustment opening, the water flow cross section of the water supply waterway, and the water flow cross section of the pressure relief waterway produce opposite changes, thereby synchronously adjusting the water supply flow and the pressure relief flow;

[0007] Water flows into the water inlet chamber from the water inlet, is divided into the water supply chamber and the pressure relief chamber through the rotating parts, and then flows out from the water outlet on the water supply chamber and the pressure relief port on the pressure relief chamber.

[0008] Furthermore, the water inlet chamber is provided with a water replenishment through hole connected to the water replenishment chamber and a pressure relief through hole connected to the pressure relief chamber. The water replenishment through hole is located on the water replenishment waterway, and the pressure relief through hole is located on the pressure relief waterway.

[0009] Furthermore, the adjustment opening extends axially along the side wall of the rotating part to form an upper adjustment opening and a lower adjustment opening. The lower adjustment opening adjusts the water flow cross-section size of the water replenishment hole on the water inlet chamber, and the upper adjustment opening adjusts the water flow cross-section size of the pressure relief water hole on the water inlet chamber.

[0010] Furthermore, an adjusting channel is provided in the rotating member, the adjusting channel is communicated with the water inlet chamber and the adjusting opening, and the water flow in the water inlet chamber flows from the adjusting channel to the adjusting opening.

[0011] Furthermore, the rotating member is driven to rotate by an external driving device, or is manually driven to rotate.

[0012] Furthermore, the water replenishing body is provided with a mounting hole for fixing the rotating part. The rotating part is rotatably set in the mounting hole and extends to the water inlet cavity. The bottom of the rotating part is engaged with the step groove on the water replenishing body through a buckle to achieve fixation.

[0013] Furthermore, when the rotating member rotates to a maximum water supply flow rate, the pressure relief flow rate is minimum; conversely, when the rotating member rotates to a minimum water supply flow rate, the pressure relief flow rate is maximum.

[0014] Furthermore, the water replenishment body is installed on the drain valve, the water inlet of the water inlet chamber is connected to the water inlet pipe, the water outlet of the water replenishment chamber is connected to the overflow pipe of the drain valve through the water replenishment pipe, and is used to replenish water into the overflow pipe, and the pressure relief port of the pressure relief chamber is connected to the toilet water tank.

[0015] Furthermore, a full-row rotating part and a half-row rotating part are provided in the water inlet chamber, which correspond to the full-row water replenishment water path and the half-row water replenishment water path respectively, and the water replenisher is connected to the full-row button and the half-row button of the drain valve; when the full-row button opens the full-row water replenishment water path, the full-row rotating part adjusts the water flow section from the water inlet chamber to the water replenishment chamber and the pressure relief chamber; and when the half-row button opens the half-row water replenishment water path, the half-row rotating part adjusts the water flow section from the water inlet chamber to the water replenishment chamber and the pressure relief chamber.

[0016] Furthermore, the water replenishing body is provided with an indicator mark for indicating the status of the rotating part.

[0017] After adopting the above solution, the beneficial effects of the utility model are:

[0018] The water replenishing body of the utility model's diversion and pressure relief water replenishing device is provided with a water inlet chamber, a water replenishing chamber and a pressure relief chamber. After the water flows into the water inlet chamber from the water inlet, it is diverted to the water replenishing chamber and the pressure relief chamber. The water in the water replenishing chamber flows to the overflow pipe of the drain valve, and the overflow pipe is connected to the water seal through the internal water channel of the toilet, while the water in the pressure relief chamber can flow to the toilet.

[0019] The water supply unit incorporates a rotating element with an adjustable opening on its sidewall that connects to the water inlet chamber. As the rotating element rotates, the overlapping area of the adjustable opening, the water flow cross-section of the water supply channel, and the water flow cross-section of the pressure relief channel change in opposite directions, achieving precise and synchronized regulation of the water supply and pressure relief volumes. During the water supply process, as the rotating element rotates, the water supply and pressure relief volumes are automatically and flexibly adjusted according to actual needs. This ensures rapid water supply while effectively releasing accumulated internal pressure, thus avoiding safety hazards such as bursting or detaching of the water supply pipe caused by high pressure maintenance in traditional water supply systems.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] The utility model provides a diversion pressure relief water replenishing device, such as Figures 1 to 10 As shown, it includes a water replenishment body 1, which is provided with a water inlet chamber 11, a water replenishment chamber 13, a pressure relief chamber 15, a water inlet 12, a water outlet 14, and a pressure relief port 16. The water outlet 14 is in communication with the water replenishment chamber 13, the pressure relief port 16 is in communication with the pressure relief chamber 15, and the pressure relief port 16 is in communication with the pressure relief chamber 15.

[0039] like Figures 1 to 3 As shown, the water inlet chamber 11 is provided with a water replenishment hole connected to the water replenishment chamber 13 and a pressure relief hole connected to the pressure relief chamber 15. Water flows into the water inlet chamber 11 through the water inlet 12 and is then divided into the water replenishment chamber 13 and the pressure relief chamber 15 through the water replenishment hole and the pressure relief hole. The water in the water replenishment chamber 13 replenishes the toilet through the water outlet 14, while the water in the pressure relief chamber 15 is directed into the toilet tank through the pressure relief port 16.

[0040] The utility model utilizes the rotating part 3 to realize the synchronous regulation of the water supply flow and the pressure relief flow of the water supply device. Figure 1 and 3 As shown, a mounting hole 17 for fixing the rotating member 3 is provided on the water replenishing body 1 , and the rotating member 3 is rotatably disposed in the mounting hole 17 and extends into the water inlet cavity 11 . Figure 4 The 3D view of the rotating member 3 is shown. The rotating member 3 is in the shape of a rotating shaft, and a buckle 33 is provided at the bottom thereof. The buckle 33 is engaged with the annular step groove 19 at the bottom of the water replenishing body 1. Figure 5 , install the rotating part 3 on the water replenishing body 1. Figure 4As shown, an adjustment opening 31 is provided on the side wall of the rotating member 3 , and an adjustment channel 32 connecting the water inlet chamber 11 and the adjustment opening 31 is provided in the middle of the rotating member 3 . The water in the water inlet chamber 11 flows from the adjustment channel 32 to the adjustment opening 31 .

[0041] The adjustment opening 31 extends axially along the sidewall of the rotating member 3 to form an upper adjustment opening 312 and a lower adjustment opening 311. The lower adjustment opening 311 and the upper adjustment opening 312 correspond to the water replenishment hole and the pressure relief hole in the water inlet chamber 11, respectively. As the rotating member 3 rotates, the overlapping area between the lower adjustment opening 312 and the water replenishment hole gradually decreases, reducing the water replenishment flow rate, while the overlapping area between the upper adjustment opening 311 and the pressure relief hole gradually increases, increasing the pressure relief flow rate. Conversely, the water replenishment flow rate increases and the pressure relief flow rate decreases. This allows flow regulation of the water replenishment chamber 13 and the pressure relief chamber 15, effectively relieving pressure while meeting water replenishment requirements, ensuring stable operation of the toilet water replenishment system.

[0042] The rotating member 3 of the present invention can be driven by an external driving device to rotate, or the rotating member 3 can be driven manually to rotate. Figure 1 and Figure 3 As shown, the water replenishment body 1 is provided with an indicator mark 8 for indicating the status of the rotating member 3. The indicator mark 8 is presented in the form of an adjustment scale. It is not only intuitive and easy to read, but also accurately reflects the current status or position of the rotating member 3. The user only needs to observe the adjustment scale to quickly understand and adjust the rotating member 3 to the desired state.

[0043] Figure 7 This is a schematic diagram of the state of the water replenishing device of the present invention on the drain valve 4. The water replenishing body 1 is installed on the drain valve 4 and connected to the button body 41. Figure 8 As shown, a mounting seat 7 is provided on the shell of the drain valve 4, and a slot 71 is provided on the mounting seat 7. A hook 18 is provided at the bottom of the water replenishment body 1, and the hook 18 cooperates with the slot 71 to mount the water replenishment body 1 on the drain valve 4.

[0044] After the water replenishment device is installed on the drain valve 4, the water inlet 12 of its water inlet chamber 11 is connected to the water inlet pipe (not shown in the figure) for filling water into the water inlet chamber 11, and the water outlet 14 of the water replenishment chamber 13 is connected to the overflow pipe 44 of the drain valve 4 through the water replenishment pipe 5. The overflow pipe 44 is connected to the water seal through the internal water channel of the toilet, so that the replenishment water of the water inlet valve can flow to the water seal of the toilet through the drain valve 4 with a diverter pressure relief water replenisher, and the pressure relief port 16 of the pressure relief chamber 15 is connected to the toilet water tank.

[0045] In order to meet the water replenishment adjustment of the double-drainage drain valve 4, the water inlet chamber 11 of this embodiment is provided with a full-row rotating member 3-1 and a half-row rotating member 3-2, which correspond to the full-row water replenishment waterway and the half-row water replenishment waterway respectively. Figure 1 and Figure 2As shown, the full-row rotating member 3 - 1 corresponds to the full-row water replenishment through hole 111 and the full-row pressure relief through hole 113 on the water inlet chamber 11 ; the half-row rotating member 3 - 2 corresponds to the half-row water replenishment through hole 112 and the half-row pressure relief through hole 114 on the water inlet chamber 11 .

[0046] When the full row water supply water channel is open, the full row rotating member 3-1 adjusts the flow rate of the water supply chamber 13 and the pressure relief chamber 15. When the half row water supply water channel is open, the half row rotating member 3-2 adjusts the flow rate of the water supply chamber 13 and the pressure relief chamber 15. Figure 6 As shown in the full row of rotating parts 3-1, when the lower regulating opening 311 completely overlaps with the water supply through hole, the water supply flow rate is the largest, and the pressure relief flow rate is the smallest; the rotating part 3 rotates, so that the overlapping area of the lower regulating opening 311 and the water supply through hole gradually decreases, and the overlapping area of the upper regulating opening 312 and the pressure relief through hole gradually increases, that is, the water supply flow rate gradually decreases and the pressure relief flow rate gradually increases; the rotating part 3 continues to rotate until the lower regulating opening 311 completely avoids the water supply through hole, Figure 6 As shown in the half row of rotating parts 3-2, after the water flows through the regulating channel 32, the lower regulating opening 311 and the upper regulating opening 312, it all flows to the pressure relief hole and enters the pressure relief chamber 15. At this time, the water replenishment flow is the smallest and the pressure relief flow is the largest, which can prevent the water replenishment body 1 and the water inlet valve from maintaining pressure and causing the water pipe to burst.

[0047] This embodiment provides a method for switching the water supply waterway using the turntable 2. Figure 3 The turntable 2 is arranged on the water supply water path of the water supply body 1, and at least one water hole 21 is opened on the turntable 2. The turntable 2 is connected to the full drain button 42 and the half drain button 43 of the drain valve 4. By pressing the full drain button 42 and the half drain button 43 of the drain valve 4 to drive the turntable 2 to rotate, the water hole 21 on the turntable 2 opens the corresponding water supply water path, realizing the water path switching, refer to Figures 9 and 10 .

[0048] like Figure 3 As shown, the water replenishment body 1 of the present invention is designed to be composed of a front shell 1-1, a middle shell 1-2, a rear shell 1-3 and a rear shell cover 1-4. Each shell can be directly welded and fixed, or fixed by bolt threaded holes. The above-mentioned water inlet 12, water outlet 14, water inlet chamber 11 and pressure relief chamber 15 are all set on the middle shell 1-2. The rear shell 1-3 covers the rear side of the middle shell 1-2 to close the water inlet chamber 11 and the pressure relief chamber 15. The bottom of the pressure relief chamber 15 is provided with a pressure relief port 16. Figure 1 and Figure 2 , water can be introduced into the toilet tank. The water replenishment chamber 13 is arranged on the front shell 1-1, and the water replenishment chamber 13 is connected to the water outlet 14. The turntable 2 is arranged between the front shell 1-1 and the middle shell 1-2.

[0049] A sealing member, preferably a sealing ring 6, is adaptively provided between each water outlet and the water passage on the water replenishing device of the present invention to improve the sealing performance of the structure and avoid water leakage.
