Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, specifically to an automatic cleaning water purifier. Background Technology

[0002] With the rapid development of industrialization and urbanization, water sources are threatened by various forms of pollution, such as industrial wastewater discharge, agricultural non-point source pollution, domestic sewage discharge, and aging pipelines. This can lead to secondary pollution of tap water during transportation, potentially resulting in impurities and harmful substances such as rust, sediment, heavy metals, bacteria, viruses, and organic matter, posing a potential threat to human health. People have increasingly higher requirements for drinking water quality, necessitating effective water purification equipment to ensure the safety and health of their drinking water. However, with existing water purifiers, the internal filter cartridges are prone to clogging due to accumulated impurities after prolonged use, affecting filtration efficiency. Furthermore, the continuous impact of water pressure when connecting external water inlet pipes can easily cause them to detach. To address these issues, an automatic cleaning water purifier is needed.

[0003] Existing water purifiers have problems such as not being able to automatically clean the internal filter cartridges during operation, and the connection between the inlet pipe and the external pipe being prone to loosening and falling off. Therefore, there is an urgent need for water purifiers with automatic cleaning function. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an automatic cleaning water purifier to solve the problems of existing water purifiers being unable to automatically clean the internal filter element and the inlet pipe and external pipe connection easily becoming loose and falling off during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic cleaning water purifier, comprising a base, a support frame installed on the bottom of the inner wall of the base, a buffer pad installed on the top of the support frame, a filter element installed on the top of the buffer pad, a water inlet chamber installed on the top of the base, a connecting plate installed on the top of the filter element, a water outlet pipe installed on the top of the connecting plate, a solenoid valve installed on the side wall of the water outlet pipe, a top cover installed on the top of the water inlet chamber, a water inlet pipe installed on the side wall of the water inlet chamber, a limit sleeve installed on the outer wall of the water inlet pipe, a rotating shaft installed on both sides of the outer wall of the limit sleeve, a clamping plate installed on the outer wall of the rotating shaft, a sealing ring installed on the inner wall of the limit sleeve, an outer connecting pipe installed on the inner wall of the limit sleeve, clamping rods installed on both sides of the outer wall of the outer connecting pipe, and a drain port opened at the bottom of the base.

[0006] Preferably, the buffer pad is snapped into place with the filter element, and the bottom of the buffer pad is tightly fitted with the top of the support frame.

[0007] Preferably, the filter element is threadedly connected to the connecting plate, and the outer periphery and inner wall of the connecting plate are designed with openings.

[0008] Preferably, the water inlet pipe is movably connected to the limiting sleeve, and the clamping plate forms a rotating structure with the limiting sleeve through a rotating shaft.

[0009] Preferably, the card plate and the card rod are engaged and connected.

[0010] Preferably, the sealing ring fits tightly with the outer tube, and the outer tube is threadedly connected to the limiting sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a support frame, buffer pad, filter element, water inlet chamber, connecting plate, water outlet pipe, solenoid valve, and top cover to connect the filter element to the connecting plate by threads, and then snap the buffer pad to the bottom of the filter element. The support frame then presses and fixes the buffer pad. When the filtered water flows out of the water outlet pipe, the solenoid valve is controlled to intermittently close the water outlet pipe, so that the water flow inside generates a water hammer effect when the solenoid valve closes the channel. This creates a backwashing force on the filter element from the inside to the outside, thus achieving a self-cleaning effect on the outer wall of the filter element. At the same time, the buffer pad can reduce the impact of the water hammer effect on the filter element and prevent damage to the filter element.

[0013] 2. This utility model uses an inlet pipe, a limiting sleeve, a rotating shaft, a clamping plate, a sealing ring, an outer pipe, a clamping rod, and a drain outlet to tightly fit the sealing ring with the inlet pipe opening. Then, the outer pipe is threadedly connected to the limiting sleeve. Finally, the clamping plate is rotated around the rotating shaft to lock the clamping plate and the clamping rod in place. This prevents the internal water flow from continuously impacting the connection between the limiting sleeve and the outer pipe, which could cause loosening and affect the sealing performance and connection stability.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Please see Figures 1-4 An automatic cleaning water purifier includes a base 1, a support frame 2 installed on the bottom inner wall of the base 1, a buffer pad 3 installed on the top of the support frame 2, a filter element 4 installed on the top of the buffer pad 3, a water inlet chamber 5 installed on the top of the base 1, a connecting plate 6 installed on the top of the filter element 4, a water outlet pipe 7 installed on the top of the connecting plate 6, a solenoid valve 8 installed on the side wall of the water outlet pipe 7, and a top cover 9 installed on the top of the water inlet chamber 5. The buffer pad 3 and the filter element 4 are engaged, and the bottom of the buffer pad 3 is tightly fitted to the top of the support frame 2. The filter element 4 is threadedly connected to the connecting plate 6, and the outer periphery and inner wall of the connecting plate 6 are designed with openings. The purifier utilizes the support frame 2, buffer pad 3, and filter element 4 to achieve the desired cleaning effect. The filter element 4, inlet chamber 5, connecting plate 6, outlet pipe 7, solenoid valve 8, and top cover 9 are connected by threads. The filter element 4 is then threaded to the connecting plate 6, and the buffer pad 3 is snapped into place at the bottom of the filter element 4. The buffer pad 3 is then pressed and fixed by the support frame 2. When the filtered water flows out of the outlet pipe 7, the solenoid valve 8 is controlled to intermittently close the outlet pipe 7. This causes the water flow inside to generate a water hammer effect when the solenoid valve 8 closes the channel, thus creating a backwashing force on the filter element 4 from the inside to the outside. This provides a self-cleaning effect on the outer wall of the filter element 4. At the same time, the buffer pad 3 reduces the impact of the water hammer effect on the filter element 4, preventing damage to the filter element 4.

[0022] Please see Figures 1-4An automatic cleaning water purifier has an inlet pipe 10 installed on the side wall of the inlet chamber 5. A limit sleeve 11 is installed on the outer wall of the inlet pipe 10. A rotating shaft 12 is installed on both sides of the outer wall of the limit sleeve 11. A clamping plate 13 is installed on the outer wall of the rotating shaft 12. A sealing ring 14 is installed on the inner wall of the limit sleeve 11. An outer connecting pipe 15 is installed on the inner wall of the limit sleeve 11. A clamping rod 16 is installed on both sides of the outer wall of the outer connecting pipe 15. A drain port 17 is provided at the bottom of the base 1. The inlet pipe 10 is movably connected to the limit sleeve 11, and the clamping plate 13 forms a rotating structure with the limit sleeve 11 via the rotating shaft 12. The clamping plate 13 is engaged with the clamping rod 16, ensuring a tight seal. The sealing ring 14 fits tightly with the outer pipe 15, and the outer pipe 15 is threadedly connected to the limiting sleeve 11. Through the water inlet pipe 10, the limiting sleeve 11, the rotating shaft 12, the clamping plate 13, the sealing ring 14, the outer pipe 15, the clamping rod 16, and the drain port 17, the sealing ring 14 is tightly fitted with the opening of the water inlet pipe 10. Then the outer pipe 15 is threadedly connected to the limiting sleeve 11. Then the clamping plate 13 is rotated around the rotating shaft 12 to make the clamping plate 13 and the clamping rod 16 engage and fix it, thereby preventing the internal water flow from continuously impacting the connection between the limiting sleeve 11 and the outer pipe 15, causing it to loosen and affecting its sealing performance and connection stability.

[0023] Working principle: In use, first move the device to the desired position, then tightly fit the sealing ring 14 with the inlet pipe 10, then thread the outer pipe 15 to the limiting sleeve 11, then rotate the clamping plate 13 around the rotating shaft 12 to lock the clamping plate 13 with the clamping rod 16, thereby preventing the internal water flow from continuously impacting the connection between the limiting sleeve 11 and the outer pipe 15, causing loosening and affecting its sealing and connection stability. Then thread the filter element 4 to the connecting plate 6, then lock the buffer pad 3 to the bottom of the filter element 4, and then connect it through the support frame 2. The buffer pad 3 is squeezed and fixed. When the filtered water flows out of the outlet pipe 7, the outlet pipe 7 is intermittently closed by controlling the solenoid valve 8. This causes the water flow inside to generate a water hammer effect when the solenoid valve 8 closes the channel, which in turn creates a backwashing force on the filter element 4 from the inside to the outside. This provides a self-cleaning effect on the outer wall of the filter element 4. At the same time, the buffer pad 3 reduces the impact of the water hammer effect on the filter element 4 and prevents damage to the filter element 4. This completes the use of the device.
