Description
Technical Field
[0001] The utility model relates to the technical field of water supply equipment, in particular to energy-saving non-negative pressure water supply equipment. Background Art
[0002] Non-negative pressure water supply refers to a special water supply method in the building's water supply system, which keeps the water supply pressure in a positive pressure state at all times and does not cause negative pressure. When the water demand increases or the water pressure drops at certain locations in the water supply system, the water supply can be kept stable, avoiding water supply interruption or insufficient pressure, improving the reliability and stability of the water supply system, ensuring that the water supply needs of various locations in the building are met, and reducing the occurrence of water supply system failures or abnormalities.
[0003] The water source in the existing non-negative pressure water supply equipment usually remains stationary for a long time, causing bacteria to grow in the internal water source, posing a safety hazard. For example, a Chinese patent with publication number CN219240708U discloses an energy-saving non-negative pressure water supply equipment, which can isolate impurities in the water through a filtering mechanism, store the water in a box, and sterilize the internal water through an ultraviolet sterilization lamp rod. The ultraviolet sterilization lamp rod can rotate and cooperate with the stirring mechanism to stir the water, thereby improving the sterilization effect. However, the equipment can only quickly replace the ultraviolet sterilization lamp rod, and when the filtering mechanism filters the water resource for a long time, a lot of impurities will accumulate inside, which needs to be cleaned and replaced. Therefore, an energy-saving non-negative pressure water supply equipment is proposed to solve the above-mentioned problems. Utility Model Content

The transmission pipe connected to the left side of the water pump extends to the inside of the water tank, and the transmission pipe on the right side extends to the top of the filtering mechanism.
[0008] When water enters the water storage tank from the water inlet pipe through the water pump connected to the transmission pipe on both sides of the water pump, the water is transmitted to the filtering mechanism for filtration, and finally stays in the water storage tank to wait for use.

[0028] When a specific operation plan is needed, the water enters the water storage tank 1 from the water inlet pipe 11 through the water pump 2 connected to the transmission pipe 21, and the water in the water storage tank 1 is transmitted by the transmission pipe 21 connected by the water pump 2, and the water is transported to the filter mechanism 3 for filtration, and finally to the water storage tank 4, where the ultraviolet lamp 43 on the water storage tank 4 sterilizes the water in the water storage tank 4, and then the water is kept still and waits for use. When the filter mechanism 3 needs to be cleaned and replaced, the side sliding door 37 is opened, the support frame 33 is pulled outward, and the bottom of the support frame 33 moves with the sliding device 32, and the pressure spring 3 in the limit device 35 is used. 52. When the support frame 33 is pulled outward, the limit block 351 connected to the top of the pressure spring 352 moves to the edge of the limit groove 36. The inclined setting on the top of the limit block 351 presses down the pressure during the movement. The pressure applied downward by the limit block 351 causes the pressure spring 352 to contract, so that the support frame 33 drives the filter tank 34 to move out of the shell 31. After the support frame 33 moves out, the collection port 341 and the filter screen 342 on the filter tank 34 are cleaned, and then the filter tank 34 is replaced. After completing the cleaning and replacement operations, the support frame 33 is pushed into the shell 31, and the side sliding door 37 is closed to seal the filter mechanism 3.

[0034] Through the above technical solution, when the support frame 33 is pulled outward, the limit block 351 connected to the top of the pressure spring 352 moves to the edge of the limit groove 36. The inclined setting of the top of the limit block 351 presses down the pressure during movement, and the pressure applied downward by the limit block 351 causes the pressure spring 352 to contract, so that the support frame 33 drives the filter tank 34 to move out of the outer shell 31, and push it back into the outer shell 31 in the same way.
[0035] Specifically, a water storage tank 4 is disposed at the bottom of the filtering mechanism 3 , a placement groove 42 is formed at the top of the water storage tank 4 , an ultraviolet lamp 43 is disposed in the placement groove 42 , and the ultraviolet lamp 43 and the placement groove 42 are engaged with each other.
[0036] When a specific operation plan is needed, the water enters the water storage tank 1 from the water inlet pipe 11 through the water pump 2 connected to the transmission pipe 21, and the water in the water storage tank 1 is transmitted by the transmission pipe 21 connected by the water pump 2, and the water is transported to the filter mechanism 3 for filtration, and finally to the water storage tank 4, where the ultraviolet lamp 43 on the water storage tank 4 sterilizes the water in the water storage tank 4, and then the water is kept still and waits for use. When the filter mechanism 3 needs to be cleaned and replaced, the side sliding door 37 is opened, the support frame 33 is pulled outward, and the bottom of the support frame 33 moves with the sliding device 32, and the pressure spring 3 in the limit device 35 is used. 52. When the support frame 33 is pulled outward, the limit block 351 connected to the top of the pressure spring 352 moves to the edge of the limit groove 36. The inclined setting on the top of the limit block 351 presses down the pressure during the movement. The pressure applied downward by the limit block 351 causes the pressure spring 352 to contract, so that the support frame 33 drives the filter tank 34 to move out of the shell 31. After the support frame 33 moves out, the collection port 341 and the filter screen 342 on the filter tank 34 are cleaned, and then the filter tank 34 is replaced. After completing the cleaning and replacement operations, the support frame 33 is pushed into the shell 31, and the side sliding door 37 is closed to seal the filter mechanism 3.
