Technical Field
[0001] This utility model relates to the field of toilet tank pressurization water supply technology, specifically a pressurization water supply structure for a toilet tank. Background Technology
[0002] In modern life, toilets are an indispensable sanitary fixture. The water supply capacity of the toilet tank directly affects the flushing effect of the toilet. Traditional toilet tank water supply structures usually rely on the gravity of the water in the tank to achieve flushing.
[0003] According to application number CN00242168.2, a toilet tank water supply device is disclosed, which includes a water storage tank connected to the drain outlet of a household appliance, a water pump, and a toilet tank. The inlet of the water pump is connected to the water storage tank, and its outlet is connected to the toilet tank. The water pump is automatically controlled by a switch. The toilet tank also has another water inlet, at which a pressure valve connected to a tap water pipe is installed. The toilet tank has a float valve inside to control the water intake at this inlet.
[0004] The water supply devices in the above cases do not have a pressurization effect, which often leads to insufficient water pressure in high-rise residential buildings, old communities, or during peak water usage periods. This results in weak water flow when flushing the toilet, incomplete flushing of waste, and the need for multiple flushes, wasting water resources. Some solutions use external booster pumps to increase water pressure, but these external devices take up a lot of space, are complicated to install, and have low integration with the water tank. Moreover, when the water pressure for flushing the toilet is sufficient, the booster pump will start by default, wasting energy. Therefore, we provide a pressurized water supply structure for toilet tanks. Utility Model Content
[0005] The purpose of this invention is to provide a pressurized water supply structure for a toilet tank to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressurized water supply structure for a toilet tank, comprising a tank body, a pressurization assembly connected to the bottom of the tank body, the pressurization assembly including a support plate, the support plate being disposed at the bottom of the tank body, a top plate being installed at the bottom of the support plate, a pressurization pump being installed at the top of the top plate, a water outlet pipe communicating with the bottom of the tank body, a toilet connection pipe being disposed on the right side of the pressurization pump, a pressure sensor being installed on the inner wall of the water outlet pipe, and flexible connectors communicating with the pressurization pump being installed on both the left and right sides of the pressurization pump. The hose has an installation pipe at the end away from the booster pump. The top end of the left installation pipe passes through the outlet pipe and extends into it, while the bottom end of the right installation pipe passes through the toilet connection pipe and extends into it. The booster assembly is equipped with a limit fixing component, which includes four connecting blocks installed on the left and right sides of the two installation pipes. Pull blocks are provided on the sides of the two connecting blocks on the same side that are far apart from each other. An adjustment block is installed on the side of the pull block closest to the connecting block, and the side of the adjustment block closest to the connecting block passes through the connecting block and extends to its outside.
[0007] Preferably, an arc-shaped block is installed on the side of the adjusting block away from the pull block, and a locking block is installed on the side of the arc-shaped block away from the pull block. The left and right sides of the water outlet pipe and the left and right sides of the toilet connecting pipe are provided with locking grooves that cooperate with the locking blocks.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-3 A pressurized water supply structure for a toilet tank includes a tank body 1. A pressurization assembly 2 is installed at the bottom of the tank body 1, and a limit fixing assembly 3 is installed on the pressurization assembly 2. A water supply pipe connected to the tank body 1 is installed on the left side of the tank body 1. A one-way valve and a switch valve are installed on the water supply pipe. A tank cover 2 is installed on the top of the tank body 1. A flush button is installed on the tank cover 2. When the user presses the flush button, the drain valve is opened by pulling the linkage or lever structure, and the water is discharged through the outlet pipe 24. As the water is discharged, the water level in the tank gradually decreases, and the float ball decreases synchronously with the water level. The float ball drives the valve disc of the inlet valve to move upward through the linkage, and the inlet valve opens. Municipal tap water flows into the tank through the water supply pipe to start replenishing water. The internal structure of the tank body 1 is already publicly available technology, so it will not be described in detail.
[0017] The booster assembly 2 includes a support plate 21, which is located at the bottom of the water tank body 1. The side of the support plate 21 closest to the water tank body 1 is in contact with the water tank body 1. A top plate 22 is fixedly connected to the bottom of the support plate 21, and a booster pump 23 is fixedly connected to the top of the top plate 22. A water outlet pipe 24 communicating with the water tank body 1 is fixedly connected to the bottom of the water tank body 1. A toilet connection pipe 25 is provided on the right side of the booster pump 23. The water discharged from the toilet connection pipe 25 is used to flush out the dirt in the toilet. A pressure sensor 26 is fixedly connected to the inner wall of the water outlet pipe 24. Flexible hoses 27 communicating with the booster pump 23 are fixedly connected to both the left and right sides of the booster pump 23. An installation pipe 28 is fixedly connected to the end of the flexible hose 27 away from the booster pump 23. The top end of the installation pipe 28 on the left side passes through the water outlet pipe 24 and extends into it. The bottom end of the installation pipe 28 on the right side passes through the toilet connection pipe 25 and extends into it. Two fastening bolts 210 that are threadedly connected to the water tank body 1 are provided at the bottom of the support plate 21.
[0018] A battery is installed on the top plate 22 and to the left of the booster pump 23. The battery supplies power to the electrical appliances. A controller is installed at the bottom of the top plate 22.
[0019] A sealing gasket 29 is fixedly connected to the end of the installation pipe 28 away from the booster pump 23. The surface of the sealing gasket 29 on the left side is in contact with the inner wall of the water outlet pipe 24, and the surface of the sealing gasket 29 on the right side is in contact with the inner wall of the toilet connection pipe 25. By setting the sealing gasket 29, the sealing performance when the installation pipe 28 on the left side is connected to the water outlet pipe 24 is improved, and the sealing performance when the installation pipe 28 on the right side is connected to the toilet connection pipe 25 is improved.
[0020] Pressure sensor 26 and booster pump 23 are electrically connected to the controller. The start threshold of pressure sensor 26 can be adjusted by the controller to accommodate water pressure differences in different regions.
[0021] By setting a pressure sensor 26, the water pressure is monitored in real time. The booster pump 23 is automatically started only when the water pressure is lower than the preset threshold, avoiding the energy waste of traditional external pumps working continuously. At the same time, the booster pump 23 improves the boosting effect. The booster pump 23 is fixed to the bottom of the water tank body 1 by the support plate 21 and the top plate 22. The hose 27 is integrated with the installation pipe 28. The overall structure is compact and does not occupy extra space.
[0022] The limiting and fixing assembly 3 includes four connecting blocks 31, which are respectively installed on the left and right sides of the two mounting tubes 28. Pull blocks 32 are provided on the sides of the two connecting blocks 31 located on the same side, away from each other. The side of the pull block 32 closest to the connecting block 31 is in contact with the connecting block 31. An adjusting block 33 is fixedly connected to the side of the pull block 32 closest to the connecting block 31. The side of the adjusting block 33 closest to the connecting block 31 passes through the connecting block 31 and extends to its outside. The side of the adjusting block 33 away from the pull block 32 is fixed. The two arc-shaped blocks 34 on the left side are in contact with the surface of the water outlet pipe 24, and the two arc-shaped blocks 34 on the right side are in contact with the surface of the toilet connection pipe 25. A locking block 35 is fixedly connected to the side of the arc-shaped block 34 away from the pull block 32. The left and right sides of the water outlet pipe 24 and the left and right sides of the toilet connection pipe 25 are provided with locking grooves 36 that cooperate with the locking blocks 35. The side of the locking block 35 near the locking groove 36 passes through the locking groove 36 and extends into it, contacting the inner wall of the locking groove 36.
[0023] A groove 37 is provided on the connecting block 31. A slider 38 is fixedly connected to the side of the adjusting block 33 near the groove 37. The slider 38 extends through the groove 37 and into the groove 37, contacting the inner wall of the groove 37. A magnet 39 is fixedly connected to the inner wall of the groove 37. An iron block 310 that attracts the magnet 39 is fixedly connected to the side of the slider 38 near the magnet 39. By setting the groove 37 and the slider 38, the stability of the adjusting block 33 when moving left and right is improved. By setting the magnet 39 and the iron block 310, the adjusting block 33 is limited, thereby ensuring the stability of the locking block 35 when inserted into the locking slot 36.
[0024] A positioning rod 4 is fixedly connected to the side of the slider 38 away from the magnet 39. A positioning groove 5 is provided on the inner wall of the slide groove 37 at the position corresponding to the positioning rod 4. The end of the positioning rod 4 near the positioning groove 5 passes through the positioning groove 5 and extends into it to slide in contact with the inner wall of the positioning groove 5. By setting the positioning rod 4 and the positioning groove 5, the stability of the slider 38 when moving left and right is improved.
[0025] Close the valve on the water supply pipe and drain the water from the tank body 1. Then pull the lever 32. The lever 32, through the adjusting block 33, moves the arc block 34 away from the installation pipe 28, causing the locking block 35 to move away from the locking groove 36. At the same time, the adjusting block 33, through the slider 38, moves the iron block 310 away from the magnet 39. Then pull down the installation pipe 28 on the left and pull up the installation pipe 28 on the right, so that the two installation pipes 28 are separated from the water outlet pipe 24 and the toilet connection pipe 25 respectively. Then loosen the fastening bolt 210 to disassemble the entire connection and pressurization assembly 2.
[0026] By setting the limiting and fixing component 3, it is convenient to quickly assemble and disassemble the installation pipe 28 and the water outlet pipe 24, and the toilet connection pipe 25 of the installation pipe 28, which improves the flexibility during maintenance.
[0027] When in use, after the user presses the toilet flush button, the water in the tank flows through the outlet pipe 24 to the toilet connection pipe 25. The pressure sensor 26 monitors the water pressure in the outlet pipe 24 in real time. If the water pressure is greater than or equal to the preset value, such as 0.2MPa, the booster pump 23 does not start, and the water flows directly into the toilet through the hose 27, the installation pipe 28 and the toilet connection pipe 25 to complete the normal pressure flush. If the water pressure is less than the preset value, the pressure sensor 26 transmits a signal to the controller, and the controller triggers the booster pump 23 to start, raising the water pressure to 0.4MPa before outputting it to ensure a powerful flush.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
