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.

[0025] The utility model provides a valve, the structure of which is as follows Figure 1 - Figure 3 As shown, it includes a valve mechanism 1, a filtering mechanism 2 and a cleaning mechanism 3.

[0026] The valve mechanism 1 includes a valve body 11 and a valve plate 12 rotatably connected to the valve body 11, a valve stem 13 is passed through the valve body 11, and the valve stem 13 is connected to the valve plate 12, one end of the valve body 11 is a water inlet 14, and the other end of the valve body 11 is a water outlet 15, and a sewage hole 31 is provided at the bottom of the valve body 11.

[0027] The filter mechanism 2 includes a filter frame 21 disposed in the valve body 11 at one end of the water inlet 14 . A filter screen 22 is disposed in the filter frame 21 . The drain hole 31 is located at the water-facing side of the filter screen 22 .

[0028] The cleaning mechanism 3 includes a first hole plug 32 disposed in the drain hole 31 .

[0029] When in use, when tap water flows into the valve body 11, the filter 22 filters out impurities carried in the tap water. Under the filtering effect of the filter 22, the possibility of impurities entering the valve body 11 is reduced, the possibility of damage to the valve plate 12 is reduced, and the sealing of the valve plate 12 is improved. The impurities filtered by the filter 22 will accumulate at the bottom of the valve body 11. The first hole plug 32 is opened regularly, and the impurities in the valve body 11 are discharged through the drain hole 31, which reduces the possibility of the filter 22 being blocked and improves the filtering effect of the filter 22.

[0030] In the utility model, under the filtering action of the filter 22, the possibility of impurities entering the valve body 11 is reduced, the possibility of the valve plate 12 being damaged is reduced, and the sealing of the valve plate 12 is improved. Under the action of the drain hole 31, the impurities filtered by the filter 22 can be discharged in time, reducing the possibility of the filter 22 being blocked and improving the filtering effect of the filter 22.

[0031] In order to improve the convenience of installing and removing the filter 22, please refer to Figure 1 In a preferred embodiment, an internal thread is provided on the inner side of the valve body 11 , and the filter frame 21 is threadedly connected to the valve body 11 .

[0032] When in use, when installing the filter screen 22, the filter frame 21 is screwed into the valve body 11. When removing the filter screen 22, the filter frame 21 is screwed out of the valve body 11. The assembly and disassembly is convenient, and the filter screen 22 is easy to clean or replace, thereby improving the filtering effect of the filter screen 22.

[0033] In order to improve the stability of the filter 22, please refer to Figure 1 In a preferred embodiment, a first slot 23 is defined in the valve body 11 , a second slot 24 corresponding to the first slot 23 is defined on the filter frame 21 , and anti-loosening blocks 25 are connected in the first slot 23 and the second slot 24 .

[0034] When in use, after the filter frame 21 is screwed into the valve body 11, the first slot 23 corresponds to the second slot 24, and the anti-loosening block 25 is inserted into the first slot 23 and the second slot 24. Under the limiting effect of the anti-loosening block 25, the possibility of the filter frame 21 rotating and loosening is reduced, thereby improving the stability of the filter frame 21.

[0035] To minimize disruption to water flow, refer to Figure 1 In a preferred embodiment, the inner side of the anti-loosening block 25 is streamlined.

[0036] When in use, when water flows through the valve body 11, the obstruction to the water flow is reduced, making the water flow smoother.

[0037] To improve the cleanliness of the filter 22, please refer to Figure 1 In a preferred embodiment, the cleaning mechanism 3 further comprises a flushing hole 33 disposed at the top of the valve body 11 , the flushing hole 33 is located on the water-facing side of the filter screen 22 , and a second hole plug 34 is disposed in the flushing hole 33 .

[0038] During use, some impurities adhering to the filter 22 have strong adhesion and are difficult to be discharged naturally through the drain hole 31. The second hole plug 34 can be opened and high-pressure water can be injected from the flushing hole 33 to flush away the impurities adhering to the filter 22, thereby improving the cleanliness of the filter 22 and the filtering effect of the filter 22.

[0039] To improve the sealing performance of the valve body 11, please refer to Figure 1 In a preferred embodiment, a sealing layer 35 is disposed on the outer sides of the first hole plug 32 and the second hole plug 34 .

[0040] When in use, the fit between the first hole plug 32 and the drain hole 31, and the fit between the second hole plug 34 and the flushing hole 33 is improved, thereby improving the sealing performance of the valve body 11 and reducing the possibility of water leakage.

[0041] To further improve the cleanliness of the filter 22, please refer to Figure 3 In a preferred embodiment, the cleaning mechanism 3 also includes a scraper rod 36 rotatably connected to the filter frame 21, the scraper rod 36 rotates along the axis of the filter frame 21, the scraper rod 36 abuts against the water-facing side of the filter screen 22, and the valve body 11 is provided with a driving component 4 for driving the scraper rod 36 to rotate.

[0042] During use, when the filter screen 22 needs to be cleaned, the drive assembly 4 drives the scraper rod 36 to rotate, and the scraper rod 36 scrapes off the impurities adhering to the filter screen 22, further improving the cleanliness of the filter screen 22 and further improving the filtering effect of the filter screen 22.

[0043] To drive the scraper rod 36 to rotate, please refer to Figure 3 In a preferred embodiment, the driving assembly 4 includes a pull rod 41 vertically slidably arranged on the top of the valve body 11, and a slider 42 is slidably connected to the scraper rod 36 along the length direction of the scraper rod 36, and the bottom end of the pull rod 41 is hinged on the slider 42.

[0044] When in use, when cleaning the filter 22, the pull rod 41 is continuously pulled up or pressed down, and the bottom end of the pull rod 41 and the slider 42 rotate relative to each other, the pull rod 41 drives the slider 42 to slide along the length direction of the scraper rod 36, and the slider 42 drives the scraper rod 36 to reciprocate along the axial direction of the filter frame 21, thereby scraping off the impurities adhering to the filter 22. The structure is simple and the transmission is efficient.

[0045] To reduce the possibility of damage to the filter 22, please refer to Figure 3 In a preferred embodiment, an elastic layer 37 is bonded to the scraper rod 36 on one side close to the filter screen 22, and the elastic layer 37 is a rubber pad.

[0046] When in use, when the scraper rod 36 abuts against the filter screen 22 , the elastic layer 37 is squeezed and deformed, and the contact between the scraper rod 36 and the filter screen 22 changes from rigid contact to flexible contact, which reduces the possibility of damage to the filter screen 22 and increases the service life of the filter screen 22 .

[0047] To facilitate pulling up or pressing down the pull rod 41, please refer to Figure 3 In a preferred embodiment, a handle 43 is fixedly connected to the top of the pull rod 41 .

[0048] When in use, the handle 43 is held to pull up or press down the pull rod 41, which reduces the possibility of slipping and makes the operation more convenient.

[0049] In order to better understand the present invention, the following Figure 1 - Figure 3 The working principle of the technical solution of a valve of the utility model is described in detail: when tap water flows into the valve body 11, the filter 22 filters out the impurities carried in the tap water. Under the filtering effect of the filter 22, the possibility of impurities entering the valve body 11 is reduced, the possibility of damage to the valve plate 12 is reduced, and the sealing of the valve plate 12 is improved. The impurities filtered by the filter 22 will accumulate at the bottom of the valve body 11. The first hole plug 32 is opened regularly, and the impurities in the valve body 11 are discharged through the drain hole 31, which reduces the possibility of the filter 22 being blocked and improves the filtering effect of the filter 22.
