Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a quick-cleaning water conveying bottom valve. Background Technology

[0002] The foot valve, also known as a check valve, ensures unidirectional flow of liquid in the suction pipe, allowing the water pump to operate normally. When the water pump stops briefly, the foot valve prevents liquid from returning to the water source tank, ensuring the suction pipe remains full of liquid to facilitate pump restart.

[0003] The bottom of the water supply foot valve has a filter cover to prevent foreign objects from being sucked in. After the water supply foot valve has been used in environments such as rivers for a period of time, screw-like foreign objects will be attached to the filter holes of the filter cover, which will affect the water intake efficiency. Therefore, it is necessary to clean the screw-like foreign objects attached to the filter cover, but cleaning the foreign objects is inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a quick-cleaning bottom valve for water supply, which facilitates the cleaning of foreign objects on the filter cover.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick-cleaning water supply bottom valve, comprising a water supply bottom valve body and a filter cover disposed at the bottom of the water supply bottom valve body. The filter cover is cylindrical, and the circumferential side of the filter cover is provided with strip-shaped filter holes extending in the vertical direction. A scraping mechanism is provided inside the filter cover to scrape impurities at the strip-shaped filter holes during downward movement. A force-applying mechanism is provided inside the filter cover to drive the scraping mechanism to move downward. The scraping mechanism includes an annular base disposed inside the filter cover, multiple scraper plates hinged to the lower surface of the annular base and capable of being embedded in the strip-shaped filter holes when rotated upward to a horizontal state, a lower pressure ring that is raised and lowered on the annular base and drives the scraper plates to rotate upward to a horizontal state during upward movement, and an elastic element disposed between the lower pressure ring and the bottom of the filter cover and driving the lower pressure ring to move upward. The force-applying mechanism includes two connecting arms threaded to the annular base and extending through the strip-shaped filter holes, and a handle disposed at one end of the connecting arms that passes through the strip-shaped filter holes.

[0006] By adopting the above technical solution, after a period of use, some foreign objects such as screws will adhere to the strip filter holes of the filter cover of the water supply bottom valve. At this time, during the cleaning process, press down on the two handles to overcome the elastic force of the elastic element of the scraping mechanism, so that the annular base, scraper plate, and lower pressure ring move downward. During this process, the scraper plate moves downward along the strip filter holes, thereby scraping off the foreign objects at the strip filter holes. Ultimately, it has the function of conveniently cleaning the foreign objects at the strip filter holes of the filter cover. At the same time, in the scraping mechanism, the rotation setting of the scraper plate, the lower pressure ring and elastic element drive the scraper plate to rotate downward to a horizontal state, thereby solving the problem of difficulty in installation due to interference when the scraper plate is directly installed. In addition, the setting of the elastic element allows the scraping mechanism to be reset when it moves downward to the limit state.

[0007] A further feature of this invention is that: a first annular tube is provided on the annular base; a lower pressure ring is sleeved on the first annular tube for lifting and lowering; a second annular tube is provided at the bottom of the filter cover; and the elastic element is a compression spring with both ends sleeved between the first and second annular tubes, with the upper and lower ends of the elastic element respectively abutting against the lower pressure ring and the bottom of the filter cover.

[0008] By adopting the above technical solution, a first annular tube is provided on the annular base, a second annular tube is provided at the bottom of the filter cover, and the elastic element is a compression spring with both ends sleeved between the first and second annular tubes, thereby achieving the limiting installation of both ends of the compression spring.

[0009] A further feature of this invention is that the bottom of the filter cover is detachably provided with a receiving cover, the second annular tube is provided on the receiving cover, and the lower end of the elastic member abuts against the receiving cover.

[0010] While using the above technical solution, some algae and other foreign matter may adhere to the compression spring. In this case, by disassembling the receiving cover, the compression spring can be removed, thereby cleaning the algae and other foreign matter attached to the inner wall of the filter cover.

[0011] A further feature of this invention is that the bottom of the receiving cover is provided with multiple sets of arc-shaped filter holes arranged in a circumferential array, and the inner diameter of each set of arc-shaped filter holes gradually increases outward.

[0012] By adopting the above technical solution and setting multiple arc-shaped filter holes, the maximum water intake of the filter cover is increased, thereby improving the water intake efficiency.

[0013] A further feature of this invention is that: a metal scraper ring for scraping slag from the inner ring of the filter cover is provided on the periphery of the annular base, and metal scraper strips for scraping slag from both sides of the scraper plate are provided on both sides of the strip-shaped filter holes.

[0014] By adopting the above technical solutions, the metal scraper ring can improve the efficiency of scraping slag from the inner ring of the filter cover, and the metal scraper strip can improve the efficiency of scraping slag from both sides of the strip-shaped filter holes.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example: A quick-cleaning type water supply foot valve, such as Figure 1 and Figure 2 As shown, the device includes a water supply bottom valve body 1 and a filter cover 2 located at the bottom of the water supply bottom valve body 1. The filter cover 2 is cylindrical, and its circumferential sides are provided with a strip-shaped filter hole 2-1 extending vertically. The filter cover 2 is provided with a scraping mechanism 3 that scrapes away impurities at the strip-shaped filter hole 2-1 during downward movement. The filter cover 2 is also provided with a force-applying mechanism 4 that drives the scraping mechanism 3 to move downward.

[0022] For example, 1 to Figure 4 As shown, the scraping mechanism 3 includes an annular base 3-1 disposed inside the filter cover 2, multiple scraper plates 3-2 hinged to the lower surface of the annular base 3-1 and capable of being embedded in the strip filter holes 2-1 when rotated upward to a horizontal state, a lower pressure ring 3-3 that is lifted and lowered on the annular base 3-1 and drives the scraper plates 3-2 to rotate upward to a horizontal state during upward movement, and an elastic element 3-4 disposed between the lower pressure ring 3-3 and the bottom of the filter cover 2 and drives the lower pressure ring 3-3 to move upward.

[0023] like Figures 1 to 4 As shown, a first annular tube 3-1-1 is provided on the annular base 3-1, and a lower pressure ring 3-3 is sleeved on the first annular tube 3-1-1 for lifting and lowering. A second annular tube 2-2-1 is provided at the bottom of the filter cover 2. The elastic element 3-4 is a compression spring with both ends sleeved between the first annular tube 3-1-1 and the second annular tube 2-2-1. The upper and lower ends of the elastic element 3-4 are respectively pressed against the lower pressure ring 3-3 and the bottom of the filter cover 2.

[0024] like Figure 2 and Figure 3 As shown, a receiving cover 2-2 is detachably provided at the bottom of the filter cover 2, and a second annular tube 2-2-1 is provided on the receiving cover 2-2. The lower end of the elastic member 3-4 abuts against the receiving cover 2-2. The bottom of the receiving cover 2-2 is provided with multiple sets of arc-shaped filter holes 2-2-2 arranged in a circumferential array, and the inner diameter of each set of arc-shaped filter holes 2-2-2 gradually increases outward.

[0025] like Figure 3 and Figure 4 As shown, the annular base 3-1 is provided with a metal scraper ring 3-1-2 for scraping slag from the inner ring of the filter cover 2, and metal scraper strips 3-2-1 for scraping slag from both sides of the scraper plate 3-2 are provided with metal scraper strips 3-2-1 for scraping slag from both sides of the strip filter hole 2-1.

[0026] like Figures 2 to 4 As shown, the force-applying mechanism 4 includes two connecting arms 4-1 threadedly connected to the annular base 3-1 and passing through the strip filter hole 2-1, and a handle 4-2 disposed at one end of the connecting arm 4-1 passing through the strip filter hole 2-1.

[0027] Implementation Effect: After a period of use, some foreign objects such as screws will adhere to the strip filter holes 2-1 of the filter cover 2. During the cleaning process, pressing down on the two handles 4-2 overcomes the elastic force of the elastic element 3-4 of the scraping mechanism 3, causing the annular base 3-1, scraper plate 3-2, and pressure ring 3-3 to move downwards. During this process, the scraper plate 3-2 moves downwards along the strip filter holes 2-1, thereby scraping away the foreign objects at the strip filter holes 2-1. Ultimately, this facilitates the cleaning of foreign objects at the strip filter holes 2-1 of the filter cover 2. At the same time, in the scraping mechanism 3, the rotation setting of the scraper plate 3-2, the pressure ring 3-3, and the elastic element 3-4 drive the scraper plate 3-2 to rotate downwards to a horizontal state, thus solving the problem of difficulty in installing the scraper plate 3-2 due to interference. In addition, the setting of the elastic element 3-4 allows the scraping mechanism 3 to be reset when it moves downwards to its limit.

[0028] A first annular tube 3-1-1 is provided on the annular base 3-1, and a second annular tube 2-2-1 is provided at the bottom of the filter cover 2. The elastic element 3-4 is a compression spring with both ends sleeved between the first annular tube 3-1-1 and the second annular tube 2-2-1, thereby achieving the limiting installation of the two ends of the compression spring. At the same time, some algae and foreign matter may adhere to the compression spring. In this case, by disassembling the receiving cover 2-2, the compression spring can be removed, thereby cleaning the algae and foreign matter adhering to the inner wall of the filter cover 2. By setting multiple arc-shaped filter holes 2-2-2, the maximum water intake of the filter cover 2 is increased, thereby improving the water intake efficiency. The setting of the metal scraper ring 3-1-2 can improve the efficiency of scraping sludge from the inner ring of the filter cover 2, and the setting of the metal scraper strip 3-2-1 can improve the efficiency of scraping sludge from both sides of the strip-shaped filter hole 2-1.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
