DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] An ultrafiltration water purifier, referring to Figure 1-4 , including a tank body 1, in which a filter element fixing device is welded, a filter element installation cavity 16 is formed between the filter element fixing device and the tank body 1, and a filter element 10 is accommodated in the filter element installation cavity 16, and a limiting component is arranged above the filter element 10, the limiting component includes a limiting transverse plate 13 and a ferrule 12, and a screw 14 is installed along the vertical thread at the center of the limiting transverse plate 13, and the bottom of the screw 14 abuts against the upper end of the filter element 10, and the filter element 10 is fixed in the filter element installation cavity 16 by the cooperation of the limiting component and the filter element fixing device, and the filter element 10 is installed in the filter element fixing device welded in the tank body 1, and the filter element 10 is initially positioned by using the filter element fixing device, and then the screw 14 on the limiting transverse plate 13 is rotated downward to support the filter element 10, so as to realize the positioning operation of the filter element 10, and the filter element 10 can be effectively prevented from falling off whether it is placed horizontally or vertically, thereby ensuring the filtering effect of the filter element 10 on water.

[0024] At the same time, no matter whether the water purifier is placed horizontally or vertically, the filter element 10 can be effectively prevented from leaving the water purifier. At the same time, it also changes the original structure of the water purifier, which requires the lid (sealing cover) to be closed and fixed before water can be passed. Now, water can be passed without closing the lid, and the purification effect of the filter element 10 can be directly observed.

[0025] Furthermore, it also includes a cover 7, which is detachably mounted at the upper opening of the tank body 1. A first water pressure gauge 5 connected to the tank body 1 is installed on the top of the cover 7, and a second water pressure gauge 3 connected to the filter element installation cavity 16 is installed on the side wall of the tank body 1, which is used to monitor the water pressure data before and after purification. A water pressure monitoring part is set at the inlet and outlet water ends of the water purifier. The use status of the filter element 10 is judged by monitoring the inlet and outlet water pressure data to avoid the situation where the water pressure of the raw water is weakened after passing through the blocked filter element 10 (it is replaced in time after blockage, or the pressure is increased by an additional booster pump), resulting in insufficient water supply or some electrical equipment cannot be used normally due to insufficient water pressure.

[0026] Furthermore, a water inlet 2 is provided on both sides of the tank body 1 below the filter element installation cavity 16, and a drain outlet 4 is provided on one side of the tank body 1 above the filter element installation cavity 16. The water inlet 2 and the drain outlet 4 have flanges or threads for connection with other equipment.

[0027] Furthermore, a clamp 6 is included, and the tank body 1 and the cover 7 are fixed together by the clamp 6.

[0028] Furthermore, the filter element fixing device includes an upper mounting ring 11 and a lower mounting ring 9. The inner diameter of the upper mounting ring 11 is the same as the diameter of the filter element 10, and the inner diameter of the lower mounting ring 9 is smaller than the diameter of the filter element 10. The filter element 10 is used to support the upper mounting ring 11 and the lower mounting ring 9 to assist in positioning the filter element 10, thereby preventing the filter element 10 from falling downward. At the same time, the filter element 10 is also sealed to prevent the raw water and the purified water from flowing through, thereby effectively isolating the raw water and the purified water.

[0029] The vertical distance between the upper mounting ring 11 and the lower mounting ring 9 is smaller than the height of the filter element 10 .

[0030] Furthermore, the ferrule 12 is symmetrically welded inside the tank body 1, and the distance between the two ferrules 12 is smaller than the diameter of the filter element 10. The bottom of the ferrule 12 is recessed inward to form a groove for the limiting cross plate 13 to be inserted. After the screw 14 is pressed tightly against the filter element 10, the filter element 10 can also be used to assist in positioning the position of the limiting cross plate 13. When disassembling later, it is only necessary to unscrew the screw 14 upwards, and then take out the limiting cross plate 13 downwards, and the filter element 10 can be replaced or maintained, and installation and disassembly are more convenient.

[0031] The upper end of the screw rod 14 is provided with a handle, so as to facilitate the installation and removal operations of the user.

[0032] Furthermore, a sealing ring 8 is embedded in the upper end wall of the tank body 1 and fits the bottom wall of the cover 7. The sealing ring 8 can improve the sealing performance of the connection between the tank body 1 and the cover 7, thereby avoiding water leakage.

[0033] The sealing ring 8 is made of rubber or silicone.

[0034] Furthermore, it also includes a removal handle 15, the lower side of the removal handle 15 is provided with an external thread, and the top of the filter element 10 is provided with a connecting sleeve 101, and the connecting sleeve 101 has a threaded hole compatible with the external thread. When the filter element 10 needs to be removed, first take out the anti-slip pressure plate, and then use the external thread at one end of the removal handle 15 to tighten it clockwise in the threaded hole of the connecting sleeve 101, and gently lift it up with your hand, you can easily take out the filter element 10 from the tank body 1 to replace or clean the filter element 10, and the operation is simpler.

[0035] It should be mentioned here that the removal handle 15, tank body 1, cover 7, limit assembly and filter element fixing device are all made of stainless steel, so that the water purifier body is not prone to rust and scaling, thereby ensuring the use effect of the water purifier.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
