[0002] A filter element is a professional term for the function of filtration and purification. It is a simple device for purifying the resources of the original fluid and separating the resources. Now, filter elements are mainly used in filtration industries such as oil filtration, air filtration, and water filtration. The filter element separates solid particles in a liquid or gas, or enables different substance components to come into full contact, accelerating the reaction time, and can protect the normal operation of equipment or the cleanliness of the air.

[0003] In the prior art, for example, a convenient-to-retract and -deploy oxygen foaming filter element for a water dispenser with the Chinese patent number: CN216629795U includes a housing, a limit plate, a baffle plate, a placement plate, a clamping plate, a guide rod, etc. Two limit plates are connected to the front side of the inner bottom of the housing, and a baffle plate is slidably connected to the front side inside the housing. When the baffle plate is in the initial state, it will contact the two limit plates.

[0004] However, in the prior art, the installation process of the oxygen foaming filter element is relatively cumbersome, the cleaning and replacement of the oxygen foaming filter element are inconvenient, and since the impurities filtered by the oxygen foaming filter element accumulate at the filter element, when a new filter element is replaced, it is easy to contact the filtered impurities, resulting in cross-contamination of the filter element. To solve the above problems, we propose an oxygen foaming filter element for preventing cross-contamination. Summary of the Utility Model

[0022] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. The embodiments of the present utility model are given for purposes of illustration and description, and are not intended to be exhaustive or to limit the present utility model to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes. Embodiment

[0023] Please refer to Figures 1-6 , the present utility model provides a technical solution: an oxygen foaming filter element for preventing cross-contamination, comprising a discharge pipe 1; a fixed plate 2, the top of the fixed plate 2 is fixedly connected to the bottom of the discharge pipe 1; a filtering device 4, the filtering device 4 is located below the fixed plate 2, and the filtering device 4 is used for filtering fluids; a connection device 3, the top of the connection device 3 is fixedly connected to the bottom of the fixed plate 2, the inner side of the connection device 3 is threadedly connected to the outer side of the filtering device 4, and the connection device 3 is used for fixedly installing the filtering device 4;

[0024] The filtering device 4 includes a fixed cylinder 41, the outer side of the fixed cylinder 41 is threadedly connected to the inner side of the connecting device 3, the inner side of the fixed cylinder 41 is fixedly connected with an ejecting device 42, and the top of the ejecting device 42 is slidably connected with a filtering assembly 43;

[0025] When in use, the filter element is fixed by the fixing plate 2, the clear fluid moves into the fixed cylinder 41, and then flows along the fixed cylinder 41 into the filtering assembly 43. After being filtered by the filtering assembly 43, the fluid flows upward into the discharge pipe 1 and then flows to the outside along the discharge pipe 1. When the filter element needs to be replaced, the user rotates the fixed cylinder 41 to remove the filtering device 4 from the connecting device 3. During the removal process, the ejecting device 42 drives the filtering assembly 43 to move upward. At this time, the filtering assembly 43 can be removed, a new filtering assembly 43 can be installed, and the removed filtering device 4 can be cleaned. Since the filtered impurities are all accumulated below the filtering assembly 43, replacing the filtering assembly 43 from above can prevent the filtered impurities from contacting the new filtering assembly 43 and contaminating the new filtering assembly 43. Moreover, the filtering device 4 is convenient to disassemble and assemble, facilitating the user to clean the filtering device 4;

[0026] By providing the ejecting device 42, the filter element is convenient to disassemble and assemble, easy to use, and convenient for the user to replace and clean the filter element. After removing the filtering device 4, replacing the filtering assembly 43 from above prevents the new filtering assembly 43 from contacting the filtered impurities, avoiding contamination of the new filtering assembly 43 and preventing cross-contamination of the oxygen foaming filter element.

[0027] The connecting device 3 includes a connecting cylinder 31, the top of the connecting cylinder 31 is fixedly connected to the bottom of the fixing plate 2, the inner side of the connecting cylinder 31 is threadedly connected to the outer side of the fixed cylinder 41, the inner side of the connecting cylinder 31 is fixedly connected with a limiting plate 32, and a sealing ring 33 is fixedly connected to the outer side of the limiting plate 32. When in use, the fixed cylinder 41 is aligned with the connecting cylinder 31, and the fixed cylinder 41 is rotated. The fixed cylinder 41 moves upward along the thread on the connecting cylinder 31. The fixed cylinder 41 drives the ejecting device 42 to move upward, and the ejecting device 42 drives the filtering assembly 43 to move upward. During the upward movement of the filtering assembly 43, it contacts the limiting plate 32, and the limiting plate 32 resists the filtering assembly 43 to prevent the filtering assembly 43 from moving upward. The filtering assembly 43 resists the ejecting device 42, and the filtering assembly 43 is clamped by the ejecting device 42 and the limiting plate 32 and fixed inside the fixed cylinder 41. The sealing ring 33 seals the threaded connection to enhance the sealing performance of the connection. Connecting the filtering device 4 through the connecting device 3 makes the filter element convenient to disassemble and assemble, easy to use, and convenient for the user to replace and clean the filter element.

[0028] The ejection device 42 includes a fixed column 421. The bottom of the fixed column 421 is fixedly connected to the inner side of the fixed cylinder 41. The top of the fixed column 421 is fixedly connected to a resilient spring 422. The top end of the resilient spring 422 is fixedly connected to a sliding column 423. A circular groove 424 is formed in the wall of the sliding column 423. The inner side of the sliding column 423 is slidably connected to the outer side of the fixed column 421, and the outer side of the sliding column 423 is slidably connected to the inner side of the fixed cylinder 41. When it is necessary to replace and clean the filter element, the fixed cylinder 41 is rotated in the reverse direction. The fixed cylinder 41 moves downward along the connecting cylinder 31. The fixed cylinder 41 drives the fixed column 421 to move downward. The fixed column 421 drives the resilient spring 422 and the sliding column 423 to move downward. The sliding column 423 drives the filter assembly 43 to move downward. The limiting plate 32 no longer abuts against the filter assembly 43. Under the influence of its own elastic force, the resilient spring 422 drives the sliding column 423 to move upward. The sliding column 423 drives the filter assembly 43 to move upward. When the filtering device 4 is removed from the connecting device 3, the sliding column 423 drives the filter assembly 43 to move upward above the fixed cylinder 41. At this time, the filter assembly 43 can be taken out from above the fixed cylinder 41, and a new filter assembly 43 can be replaced. By providing the ejection device 42, when the filtering device 4 is removed, the filter assembly 43 is automatically ejected, which is convenient for the user to replace and clean the filter assembly 43. Moreover, after the filtering device 4 is removed, the user can easily clean the impurities in the filtering device 4, which is convenient for the user to clean up.

[0029] The filter assembly 43 includes a cylinder 431. The top of the cylinder 431 is slidably connected to the bottom of the limiting plate 32. The outer side of the cylinder 431 is slidably connected to the inner side of the fixed cylinder 41. The bottom of the cylinder 431 is fixedly connected to a sliding rod 432. The outer side of the sliding rod 432 is slidably connected to the inner side of the circular groove 424. During use, the sliding rod 432 is inserted into the circular groove 424. The sliding rod 432 fixes the cylinder 431. Through the cooperation of the sliding rod 432 and the circular groove 424, the filter assembly 43 is fixed, preventing the filter assembly 43 from rotating during use and affecting the filtering effect.

[0030] A sieve plate 433 is fixedly connected to the inner side of the cylinder 431. A first sieve mesh 434 is fixedly connected to the top inside the cylinder 431. The outer side of the first sieve mesh 434 is fixedly connected to a second sieve mesh 435. During use, the cleaning fluid moves into the fixed cylinder 41 and then flows along the fixed cylinder 41 into the cylinder 431. The fluid flows upward through the sieve plate 433 along the cylinder 431, and then flows along the cylinder 431 to the second sieve mesh 435. After the fluid is filtered by the second sieve mesh 435, it flows upward to the first sieve mesh 434. The fluid passes through the first sieve mesh 434 and flows upward. The fluid is filtered by the filter assembly 43. Through multiple filtrations, the filtering and adsorption performance is enhanced, ensuring the filtering effect of the filter element and improving the safety.

[0031] Working principle:

[0032] During use, the sliding rod 432 is inserted into the circular groove 424. The sliding rod 432 fixes the cylinder 431, so that the filter assembly 43 will not rotate or shift. When installing the filter element, align the fixed cylinder 41 with the connecting cylinder 31 and rotate the fixed cylinder 41. The fixed cylinder 41 moves upward along the thread on the connecting cylinder 31. The fixed cylinder 41 drives the fixed column 421 to move upward. The fixed column 421 drives the return spring 422 and the sliding column 423 to move upward. The sliding column 423 drives the filter assembly 43 to move upward. During the upward movement of the filter assembly 43, it contacts the limit plate 32. The limit plate 32 resists the filter assembly 43 to prevent the filter assembly 43 from moving upward. The filter assembly 43 resists the sliding column 423. At this time, the fixed column 421 continues to drive the return spring 422 to move upward. Since the return spring 422 is subjected to the pressure exerted by the fixed column 421 and the sliding column 423, the return spring 422 compresses. Affected by its own elastic force, the return spring 422 exerts an upward pressure on the sliding column 423. The sliding column 423 exerts an upward pressure on the filter assembly 43. The filter assembly 43 is clamped by the sliding column 423 and the limit plate 32 and fixed inside the fixed cylinder 41;

[0033] When it is necessary to replace and clean the filter element, rotate the fixed cylinder 41 in the reverse direction. The fixed cylinder 41 moves downward along the connecting cylinder 31. The fixed cylinder 41 drives the fixed column 421 to move downward. The fixed column 421 drives the return spring 422 and the sliding column 423 to move downward. The sliding column 423 drives the filter assembly 43 to move downward. The limit plate 32 no longer resists the filter assembly 43. Affected by its own elastic force, the return spring 422 drives the sliding column 423 to move upward. The sliding column 423 drives the filter assembly 43 to move upward. When the filtering device 4 is removed from the connecting device 3, the sliding column 423 drives the filter assembly 43 to move upward above the fixed cylinder 41. At this time, the filter assembly 43 can be taken out from above the fixed cylinder 41 and a new filter assembly 43 can be replaced;

[0034] During use, the filter element is fixed by the fixing plate 2. The cleaning fluid moves into the fixed cylinder 41 and then flows along the fixed cylinder 41 into the cylinder 431. The fluid flows upward through the sieve plate 433 along the cylinder 431 and then flows along the cylinder 431 to the second sieve mesh 435. After the fluid is filtered by the second sieve mesh 435, it flows upward to the first sieve mesh 434. The fluid passes through the first sieve mesh 434 and flows upward into the discharge pipe 1 and then flows to the outside along the discharge pipe 1.
