Description

Technical Field

[0001] This utility model relates to the field of toilet water supply technology, and in particular to a water storage tank that can provide a quantitative amount of water for flushing toilets. Background Technology

[0002] The toilet tank is the key component for enabling the toilet to flush. It mainly consists of the tank body, inlet valve, drain valve, float ball, and flush button. Its working principle is as follows: when the flush button is pressed, the drain valve in the tank is opened, and water in the tank quickly flows into the toilet, completing the flushing action. At the same time, the inlet valve starts working, refilling the tank with water until the water level reaches the set height, and then stops. This cycle repeats to ensure that the tank can automatically replenish water and maintain a suitable water level.

[0003] However, when the water supply is interrupted, the toilet tank usually has a fixed water capacity, which can only support 1-2 standard flushes. Once the water is used up, it cannot be refilled due to the water outage, and subsequent flushes will be completely impossible. Waste cannot be discharged in time, which not only affects the hygiene of the bathroom, but also causes great inconvenience to families or public places. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a water storage tank that can quantitatively provide water for toilet flushing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water storage tank capable of quantitatively providing toilet flushing water, comprising an outer shell, wherein the front surface of the outer shell is semi-circular, the rear surface is flat, and two hooks are fixedly installed on the top edge of the rear surface; an exhaust pipe and a water supply pipe are respectively installed on the left and right ends of the front surface of the outer shell, and a drain pipe is installed on the bottom edge of the front surface of the outer shell; mounting brackets are fixedly installed inside the outer shell at the exhaust pipe, the water supply pipe, and the drain pipe; a spring rod is fixedly installed inside the mounting bracket, and a socket sleeved on the mounting bracket is fixedly installed at the telescopic end of the spring rod; a sealing plug is provided inside the exhaust pipe, the water supply pipe, and the drain pipe, and the three sealing plugs are fixedly connected to the sockets at the corresponding positions.

[0006] Preferably, a pair of fixing frames are fixedly installed on the bottom edge of the socket at the exhaust pipe in both the horizontal and vertical directions, and a lower bracket and an upper bracket are respectively provided through the bottom edge of the mounting bracket at the exhaust pipe in both the horizontal and vertical directions.

[0007] Preferably, the bottom edge of the lower insert is U-shaped and staggered from the bottom edge of the upper insert. A pair of locking frames are fixedly installed on the top edges of both the upper and lower inserts. The pair of locking frames of the upper insert engages with a pair of fixing frames in the horizontal direction of the socket, and the pair of locking frames of the lower insert engages with a pair of fixing frames in the vertical direction of the socket.

[0008] Preferably, an upper pull wire is fixedly installed on the bottom edge of the upper bracket. One end of the upper pull wire extends horizontally toward the water supply pipe and bends obliquely upward near the water supply pipe and is fixedly installed on the top edge inside the outer casing. A lower pull wire is fixedly installed on the bottom edge of the lower bracket. The lower pull wire extends vertically toward the water discharge pipe and bends obliquely downward near the water discharge pipe and is fixedly installed on the bottom edge inside the outer casing.

[0009] Preferably, two pairs of wire loops are fixedly installed inside the housing, the two pairs of wire loops corresponding to the upper pull wire and the lower pull wire respectively, and one of the two pairs of wire loops is located close to the exhaust pipe, while the other wire loop is located at the turning point of the upper pull wire and the lower pull wire.

[0010] Preferably, pressure arms are fixedly installed on the surface of the sockets at the water supply pipe and the water outlet pipe, and the bent portions of the pull-up cable and the pull-down cable pass through the pressure arms at the water supply pipe and the water outlet pipe, respectively.

[0011] Preferably, both the water supply pipe and the water discharge pipe are rotatably connected to a gear shaft, and the sealing plug end faces inside the water supply pipe and the water discharge pipe are fixedly installed with racks that mesh with the adjacent gear shafts.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up an outer shell, filling the outer shell with water, and connecting it to the toilet tank through a drain pipe, even if the main water tap is turned off, the outer shell is still full of water, so the toilet water will not stop flowing and the toilet can be flushed.

[0013] 2. In this utility model, by setting an upper pull line and an upper insert bracket, in conjunction with the corresponding card frame and fixed frame, the socket is pulled to move the sealing plug. When adding water, the exhaust pipe opens simultaneously to quickly expel air from the outer shell, preventing air from accumulating and forming an "airlock," allowing water to smoothly fill the entire outer shell and improving the water filling speed. Similarly, by setting a lower pull line and a lower insert bracket, in conjunction with the corresponding card frame and fixed frame, the socket is pulled to move the sealing plug. When discharging water, the exhaust pipe opens simultaneously to balance the air pressure inside and outside the outer shell, preventing negative pressure from forming inside, which could cause water flow interruption or unstable flow rate, ensuring even and continuous water replenishment to the toilet tank.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] like Figures 1-6 As shown, a water tank that can quantitatively supply water for flushing toilets includes an outer shell 1. The front surface of the outer shell 1 is semi-circular, and the rear surface is flat. Two hooks 2 are fixedly installed on the top edge of the rear surface, which facilitates fixing the outer shell 1 to the wall. An exhaust pipe 3 and a water supply pipe 4 are respectively installed on the left and right ends of the front surface of the outer shell 1, and a drain pipe 5 is installed on the bottom edge of the front surface of the outer shell 1. The exhaust pipe 3 allows air inside the outer shell 1 to be expelled when water is added to the outer shell 1 through the water supply pipe 4, ensuring that the outer shell 1 is filled with water. Similarly, opening the exhaust pipe 3 ensures that the air pressure inside and outside the outer shell 1 is equal when water is added to the toilet tank through the drain pipe 5, ensuring that the water level inside the outer shell 1 is stable. The water flows out; inside the outer casing 1, mounting brackets 9 are fixedly installed at the exhaust pipe 3, water supply pipe 4, and water discharge pipe 5. A spring rod 18 is fixedly installed inside the mounting bracket 9, and a socket 12 sleeved on the mounting bracket 9 is fixedly installed at the telescopic end of the spring rod 18. A sealing plug 8 is provided inside the exhaust pipe 3, water supply pipe 4, and water discharge pipe 5, and the three sealing plugs 8 are fixedly connected to the corresponding sockets 12. Under normal circumstances, the mounting bracket 9 is used to fix the position of the spring rod 18, and the elasticity of the spring rod 18 is used to push the socket 12 to move the sealing plug 8, thereby using the sealing plug 8 to block the corresponding exhaust pipe 3, water supply pipe 4, and water discharge pipe 5.

[0019] like Figure 4As shown, a pair of fixing frames 13 are fixedly installed on the bottom edge of the socket 12 at the exhaust pipe 3 in both the horizontal and vertical directions. A lower insert 10 and an upper insert 11 are respectively installed through the bottom edge of the mounting bracket 9 at the exhaust pipe 3 in both the horizontal and vertical directions. The bottom edge of the lower insert 10 is U-shaped and staggered from the bottom edge of the upper insert 11. A pair of locking frames 14 are fixedly installed on the top edges of both the upper insert 11 and the lower insert 10. The pair of locking frames 14 of the upper insert 11 engages with the pair of fixing frames 13 in the horizontal direction of the socket 12, and the pair of locking frames 14 of the lower insert 10 engages with the pair of fixing frames 13 in the vertical direction of the socket 12. In use, when the lower insert 10 is lowered under external pulling force, the locking frames 14 on the lower insert 10 will pull the corresponding overlapping fixing frames 13 down, thereby allowing the socket 12 to overcome the thrust of the spring rod 18 and descend. This allows the sealing plug 8 to disengage from the exhaust pipe 3, opening the exhaust pipe 3, and allowing the lower insert 10 to... When the locking frame 14 pulls the horizontal fixing frame 13 on the socket 12 to lower the socket 12, the fixing block at the vertical position on the socket 12 will slide downward within the locking frame 14 in the upper bracket 11, without lowering the locking frame 14 in the upper bracket 11, thus ensuring that the upper bracket 11 will not lower; or when the upper bracket 11 is lowered under external pulling force, the locking frame 14 on the upper bracket 11 will pull the corresponding overlapping fixing frame 13 to lower, thereby enabling the socket 12 to overcome the thrust of the spring rod 18 and lower, thus enabling the sealing plug 8 to disengage from the exhaust pipe 3 and opening the exhaust pipe 3. When the locking frame 14 on the upper bracket 11 pulls the vertical fixing frame 13 on the socket 12 to lower the socket 12, the fixing block at the horizontal position on the socket 12 will slide downward within the locking frame 14 in the lower bracket 10, without lowering the locking frame 14 in the lower bracket 10, thus ensuring that the lower bracket 10 will not lower.

[0020] An upper pull cable 6 is fixedly installed on the bottom edge of the upper bracket 11. One end of the upper pull cable 6 extends horizontally towards the water supply pipe 4, and the end near the water supply pipe 4 is bent upwards and fixedly installed on the top edge inside the outer casing 1. A lower pull cable 7 is fixedly installed on the bottom edge of the lower bracket 10. The lower pull cable 7 extends vertically towards the drain pipe 5, and the end near the drain pipe 5 is bent downwards and fixedly installed on the bottom edge inside the outer casing 1. Two pairs of wire loops 17 are fixedly installed inside the outer casing 1. The two pairs of wire loops 17 correspond to the upper pull cable 6 and the lower pull cable 7 respectively. One of the two pairs of wire loops 17 is located near the exhaust pipe 3, and the other wire loop 17 is located at the junction of the upper pull cable 6 and the lower pull cable 7. Figure 3 As shown, when the upper pull wire 6 is pulled by pressure, the upper insert 11 is lowered under the guidance of the corresponding threading ring 17. When the lower pull wire 7 is pulled by pressure, the lower insert 10 is lowered under the guidance of the corresponding threading ring 17.

[0021] Pressure arms 19 are fixedly installed on the surfaces of the sockets 12 at both the water supply pipe 4 and the water outlet pipe 5. The bent portions of the upper pull cable 6 and the lower pull cable 7 pass through the pressure arms 19 at the water supply pipe 4 and the water outlet pipe 5, respectively. Gear shafts 15 are rotatably connected inside both the water supply pipe 4 and the water outlet pipe 5. A rack 16, meshing with the adjacent gear shaft 15, is fixedly installed on the end face of the sealing plug 8 inside both the water supply pipe 4 and the water outlet pipe 5. In this design, the gear shaft 15 can be driven to rotate by installing a handwheel or by installing a motor. Figure 5 As shown, the gear shaft 15 rotates to engage the rack 16, which rises to push the corresponding sealing plug 8 upward, overcoming the thrust of the spring rod 18 and opening the drain pipe 5. At this time, the pressure arm 19 connected to the socket 12 will press the diagonal line of the pull-down cable 7, causing the pull-down cable 7 to pull the lower bracket 10 down. Figure 6 As shown, the rack 16, which is engaged by the rotation of the gear shaft 15, descends and pushes the corresponding sealing plug 8 down to overcome the thrust of the spring rod 18 and open the water supply pipe 4. At this time, the pressure arm 19 connected to the socket 12 will press the inclined line of the pull cable 6 to bend, thereby pulling the upper plug bracket 11 down.

[0022] In addition, all components located inside the outer casing 1 in the above scheme, such as the mounting bracket 9, socket 12, card frame 14, fixing frame 13, sealing plug 8, pull-up cable 6, and pull-down cable 7, are made of food-grade stainless steel to prevent rusting or water pollution inside the outer casing 1.

[0023] The method of using this utility model is as follows: When water needs to be added into the outer casing 1 The gear shaft 15 at the water supply pipe 4 rotates, causing the meshing rack 16 to descend, which in turn pushes the sealing plug 8 inside the water supply pipe 4 to descend, opening the water supply pipe 4. When the sealing plug 8 descends, the socket 12 fixed to it descends synchronously, and the pressure arm 19 on the socket 12 presses the bent part of the pull wire 6.

[0024] Guided by the threading ring 17, the upper pull cable 6 is pulled, causing the upper insert 11 at the exhaust pipe 3 to descend. The retaining frame 14 of the upper insert 11 pulls the fixing frame 13 of the exhaust pipe 3 socket 12, causing the socket 12 to descend against the thrust of the spring rod 18, opening the exhaust pipe 3. The water supply pipe 4 and the exhaust pipe 3 open simultaneously, and external water is injected into the outer casing 1 through the water supply pipe 4, while internal air is discharged through the exhaust pipe 3 until the outer casing 1 is full of water. The drive gear shaft 15 is stopped, the spring rod 18 returns to its original position, and the sealing plug 8 is pushed to re-seal the water supply pipe 4 and the exhaust pipe 3.

[0025] When the toilet tank needs to be refilled The gear shaft 15 at the drain pipe 5 rotates, causing the meshing rack 16 to rise, which in turn pushes the sealing plug 8 inside the drain pipe 5 to rise, opening the drain pipe 5. When the sealing plug 8 rises, the socket 12 fixed to it rises synchronously. The pressure arm 19 on the socket 12 presses the bent part of the pull-down cable 7. The pull-down cable 7 is pulled under the guidance of the wire ring 17, causing the lower bracket 10 at the exhaust pipe 3 to descend.

[0026] The retaining frame 14 of the lower insert 10 pulls the fixing frame 13 of the vent pipe 3 socket 12, causing the socket 12 to descend against the thrust of the spring rod 18, opening the vent pipe 3. Simultaneously, the drain pipe 5 and the vent pipe 3 open, allowing water inside the outer casing 1 to flow into the toilet tank through the drain pipe 5, while external air enters through the vent pipe 3, ensuring a smooth water flow. The drive gear shaft 15 stops, the spring rod 18 resets, and the sealing plug 8 re-seals the drain pipe 5 and the vent pipe 3.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
