Technical Field

[0001] This utility model relates to the field of water supply equipment technology, specifically to a tank-type negative pressure-free water supply equipment. Background Technology

[0002] Tank-type negative pressure-free water supply equipment is a water supply device based on pump technology and pressure control system design. It is widely used in urban, rural, and industrial fields, especially in places requiring stable water supply. It mainly uses negative pressure-free technology to avoid water pressure fluctuations or negative pressure phenomena caused by water towers and pipe networks in traditional water supply systems, thereby ensuring the stability and reliability of the water supply.

[0003] Patent specification CN 220953663U discloses a tank-type negative pressure-free water supply device. The device includes a tank body with an inlet pipe at the top and a drain pipe at the bottom. Inside the tank are a filter assembly for water filtration and a cleaning assembly for removing dirt. The filter assembly includes an activated carbon filter plate, a deodorizing plate, and a fine filter plate below the activated carbon filter plate. A connecting rod is located in the middle of the activated carbon filter plate. This invention achieves water filtration through the filter assembly, multiple filtrations through the activated carbon and fine filter plates to improve water cleanliness, and removal of odors through the deodorizing plate to improve user comfort and prevent excessive odors from affecting usability.

[0004] However, in implementing the relevant technology, the above-mentioned tank-type negative pressure water supply equipment has the following problems: the tank cover cannot be opened during use, the filter plate is inconvenient to disassemble and assemble, and the top of the filter plate cannot be effectively cleaned. Therefore, we propose a tank-type negative pressure water supply equipment. Utility Model Content

[0005] This utility model proposes a tank-type negative pressure-free water supply device, which solves the problems of inconvenient disassembly and assembly of filter plates, inconvenient opening of tank cover, and insufficient sealing in related technologies.

[0006] The technical solution of this utility model is as follows:

[0007] A tank-type negative pressure-free water supply device includes a tank, an inlet pipe, and a chute. The inner wall of the top of the tank has symmetrically arranged movable grooves. A pull rod is movably installed on the inner wall of each movable groove. One end of the pull rod has a limit block. Springs are installed on the outer wall of each pull rod. A tank cover is movably installed on the top of the tank via the limit block. An inlet pipe is located on the top of the tank cover. A sealing block is located at the bottom of the tank cover. A connecting block is located at the bottom of the sealing block. A guide hole is located at the center of the sealing block and the connecting block. The inlet pipe and the guide hole are interconnected. A sealing cavity is provided inside the tank. An installation block is located on the inner wall of the sealing cavity. An activated carbon layer is movably installed in the sealing cavity via the installation block. The activated carbon layer is filled with activated carbon. A filter screen is located on the top of the activated carbon layer. An electromagnetic flow valve is installed at the bottom of the tank.

[0008] Preferably, a fixing groove is provided at the middle position of the connecting block, and the fixing groove fits into the limiting block.

[0009] Preferably, the sealing block has an inverted conical structure, and the sealing block fits into the top of the sealing cavity.

[0010] Preferably, a drive motor is installed at the center of the bottom of the tank, and the drive shaft of the drive motor extends through the bottom of the tank to the inside of the sealed cavity and is connected to a rotating shaft. A cleaning rod is provided on the outer wall of the rotating shaft.

[0011] Preferably, the cleaning rods are evenly distributed around the rotating shaft, and the outer wall of the cleaning rods fits against the inner wall of the sealing cavity.

[0012] Preferably, the top end of the rotating shaft extends through the activated carbon layer to the outer wall of the filter screen and is connected to a cleaning brush, which is in contact with the outer wall of the filter screen.

[0013] Preferably, the outer wall of the tank is symmetrically provided with sliding grooves, and a fixing ring is movably installed on the tank through the sliding grooves. The inner wall of the fixing ring is symmetrically provided with sliders, and the sliders are matched with the sliding grooves.

[0014] Preferably, the inner wall of the fixing ring is symmetrically provided with extrusion grooves, which are located on the side wall of the pull rod and fit into each other.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, a tank, an inlet pipe, and a guide hole are provided. Clean water is injected into the tank through the inlet pipe, and the water enters the sealed cavity through the guide hole. The water flow first passes through the filter screen for filtration, and then flows into the activated carbon layer for deodorization. The electromagnetic flow valve is opened to allow the filtered and deodorized clean water to flow out for use. Over time, impurities will accumulate on the inner wall of the tank. The drive motor is started to rotate the shaft, which in turn drives the cleaning rod and cleaning brush to rotate. When the cleaning rod rotates, it scrapes the inner wall of the tank to clean it, and when the cleaning brush rotates, it continuously scrapes the outer wall of the filter screen. This structure can effectively prevent impurities from clogging the filter screen pores and affecting the filtration effect of the water flow.

[0017] 2. In this utility model, by using the sliding groove, slider, and pull rod, when the can needs to be opened, the slider and sliding groove limit the fixed ring, causing the squeezing groove to move away from the side of the pull rod. Previously, the spring was in a compressed state. When the squeezing groove stops limiting the pull rod, the elastic force generated by the spring compression deformation drives the limiting block to move away from the middle fixed groove of the connecting block, retracting back into the interior of the movable groove. The can cover can be removed from the top of the sealing cavity. This structure facilitates the disassembly and replacement of the filter screen and the replacement of the activated carbon layer, and also allows for simple maintenance. Attached Figure Description

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: As Figures 1-6 As shown, this embodiment proposes a tank-type negative pressure-free water supply device, including a tank body 1, an inlet pipe 3, and a chute 5. The inner wall of the top of the tank body 1 is symmetrically provided with movable grooves 8. A pull rod 9 is movably installed on the inner wall of the movable groove 8. A limit block 11 is provided at one end of the pull rod 9. Springs 10 are installed on the outer wall of each pull rod 9. A tank cover 2 is movably installed on the top of the tank body 1 via the limit block 11. The top of the tank cover 2 is provided with the inlet pipe 3, and a sealing block 12 is provided at the bottom of the tank cover 2. A connecting block 13 is provided at the bottom of the tank. A guide hole 14 is provided at the center of the sealing block 12 and the connecting block 13. The water inlet pipe 3 and the guide hole 14 are connected to each other. A sealing cavity 15 is provided inside the tank body 1. An installation block 16 is provided on the inner wall of the sealing cavity 15. An activated carbon layer 17 is movably installed in the sealing cavity 15 through the installation block 16. The activated carbon layer 17 is filled with activated carbon. A filter screen 18 is provided at the top of the activated carbon layer 17. An electromagnetic flow valve 22 is installed at the bottom of the tank body 1.

[0028] In this embodiment, a drive motor 19 is installed at the center of the bottom of the tank 1. The drive shaft of the drive motor 19 extends through the bottom of the tank 1 to the inside of the sealed cavity 15 and is connected to a rotating shaft 20. A cleaning rod 21 is provided on the outer wall of the rotating shaft 20.

[0029] In this embodiment, the cleaning rods 21 are evenly distributed around the rotating shaft 20, and the outer wall of the cleaning rods 21 is in contact with the inner wall of the sealing cavity 15.

[0030] In this embodiment, the top end of the rotating shaft 20 extends through the activated carbon layer 17 to the outer wall of the filter screen 18 and is connected to a cleaning brush 23, which is in contact with the outer wall of the filter screen 18.

[0031] Specific examples Figure 1 , Figure 5 and Figure 6 As shown, when using this structure, clean water is injected into the tank 1 through the water inlet pipe 3. The water enters the sealed cavity 15 through the guide hole 14. The water flow first passes through the filter screen 18 for filtration, and then flows into the activated carbon layer 17 for deodorization. The electromagnetic flow valve 22 is opened to let the filtered and deodorized clean water flow out for use. After long-term use, impurities will accumulate on the inner wall of the tank 1. The drive motor 19 is started to drive the rotating shaft 20 to rotate. The rotating shaft 20 drives the cleaning rod 21 and the cleaning brush 23 to rotate. When the cleaning rod 21 rotates, it will scrape the inner wall of the tank 1 to clean the inner wall. When the cleaning brush 23 rotates, it can continuously scrape the outer wall of the filter screen 18. This structure can effectively prevent impurities from clogging the filter holes of the filter screen 18 and affecting the filtration effect of the water flow.

[0032] Example 2: A fixing groove is provided in the middle of the connecting block 13, and the fixing groove fits into the limiting block 11.

[0033] In this embodiment, the sealing block 12 has an inverted conical structure, and the top of the sealing block 12 fits into the sealing cavity 15.

[0034] In this embodiment, the outer wall of the tank body 1 is symmetrically provided with sliding grooves 5, and the tank body 1 is movably installed with a fixing ring 4 through the sliding grooves 5. The inner wall of the fixing ring 4 is symmetrically provided with sliders 7, and the sliders 7 and the sliding grooves 5 are matched with each other.

[0035] In this embodiment, the inner wall of the fixing ring 4 is symmetrically provided with extrusion grooves 6, which are located on the side wall of the pull rod 9 and fit together with it.

[0036] Specific examples Figures 2-4 As shown, when using this structure, when it is necessary to open the can 1, the fixed ring 4 is limited by the slider 7 and the groove 5. The fixed ring 4 is slid down to make the squeezing groove 6 leave the side of the pull rod 9. Previously, the spring 10 was in a compressed state. When the squeezing groove 6 stops limiting the pull rod 9, the elastic force generated by the compression deformation of the spring 10 drives the limiting block 11 to leave the middle fixed groove of the connecting block 13 and return to the inside of the movable groove 8. The can cover 2 can be removed from the top of the sealing cavity 15. This structure makes it easy to disassemble and install the filter screen 18 to replace the activated carbon layer 17, and also allows for simple maintenance.

[0037] Working principle: The sealing block 12 and sealing cavity 15 maintain the airtightness of the tank 1. Clean water is injected into the tank 1 through the water inlet pipe 3. The water enters the sealing cavity 15 through the guide hole 14. The water flow first passes through the filter screen 18 for filtration, and then flows into the activated carbon layer 17 for deodorization. The electromagnetic flow valve 22 is opened to allow the filtered and deodorized water to flow out for use. Over time, impurities will accumulate on the inner wall of the tank 1. The drive motor 19 is started to drive the rotating shaft 20 to rotate. The rotating shaft 20 drives the cleaning rod 21 and cleaning brush 23 to rotate. When the cleaning rod 21 rotates, it scrapes the inner wall of the tank 1 to clean it. When the cleaning brush 23 rotates, it continuously scrapes the outer wall of the filter screen 18, which can effectively prevent impurities from clogging the filter holes of the filter screen 18 and affecting the filtration effect of the water flow. When it is necessary to open the canister 1, the slider 7 and the groove 5 limit the fixed ring 4, and the fixed ring 4 is slid down to make the squeezing groove 6 move away from the side of the pull rod 9. Previously, the spring 10 was in a compressed state. When the squeezing groove 6 stops limiting the pull rod 9, the elastic force generated by the compression deformation of the spring 10 drives the limiting block 11 to move away from the middle fixed groove of the connecting block 13 and return to the inside of the movable groove 8. The canister cover 2 is removed from the top of the sealing cavity 15, and the activated carbon layer 17 is removed from the inner wall of the mounting block 16, which facilitates the removal and replacement of the filter screen 18 and the replacement of the activated carbon layer 17. At the same time, simple maintenance can be performed. When in use, the device can filter and deodorize, facilitate the removal and replacement of the activated carbon layer 17 and the filter screen 18, and perform self-cleaning of the inner wall of the canister 1 to prevent impurities from clogging the filter holes of the filter screen 18 and improve the user experience.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
