[0023] The following further describes the present application in detail with reference to the attached Figure 1 - attached Figure 5 drawings.

[0024] The embodiment of the present application discloses a filter for a ventilator that is convenient for cleaning and replacement. Refer to Figures 1-5, A filter for a ventilator that is convenient for cleaning and replacement, including a hydrogen-oxygen ventilator body 1. A detachable bottom connecting pipe 4 is installed at the top of the hydrogen-oxygen ventilator body 1. The top of the bottom connecting pipe 4 is fixed with an installation pipe 6. A sleeve 7 is sleeved on the installation pipe 6. A filter element 9 is placed on the top surface of the sleeve 7. A top connecting pipe 5 is installed on the bottom connecting pipe 4 by means of a thread. A positioning ring 20 is fixed above the filter element 9 inside the top connecting pipe 5; during use, the material used for filtration can be placed inside the filter element 9, and then the filter element 9 is placed on the sleeve 7. Then, by rotating the top connecting pipe 5 clockwise, it is installed on the bottom connecting pipe 4, so that the positioning ring 20 is closely attached to the top surface of the filter element 9. At this time, the filter element 9 is firmly clamped between the top connecting pipe 5 and the sleeve 7, forming a stable structure. This design not only ensures the quick replacement of the filter element 9 but also improves the overall sealing performance of the filter.

[0025] It is worth mentioning that the filter of the present application also has excellent cleaning convenience. When the filter element 9 needs to be cleaned, just rotate the top connecting pipe 5 counterclockwise, remove it from the bottom connecting pipe 4, and then the filter element 9 can be easily taken out for cleaning. After cleaning, reinstall it according to the above steps. This design not only simplifies the cleaning process but also improves the service life of the filter.

[0026] The filter for a ventilator that is convenient for cleaning and replacement disclosed in the embodiment of the present application, by optimizing the fixing method of the filter element 9, not only realizes the quick replacement of the filter element 9 but also improves the overall sealing performance and cleaning convenience of the filter. This filter has a wide application prospect in actual applications and can bring a more convenient and efficient use experience to ventilator users.

[0027] Referring to Figure 5 , a limit pipe 8 is fixed at the top of the sleeve 7; the filter element 9 can be placed inside the limit pipe 8, which can increase the stability of the filter element 9 during actual use and make it not easy to shake.

[0028] Referring to Figure 3 and Figure 4, two limiting pieces 11 are fixed on the outer wall of the bottom connecting pipe 4, and mounting pieces 13 are fixed on the outer wall of the top connecting pipe 5 above the two limiting pieces 11. A sliding rod 14 penetrates through the mounting piece 13. The top end of the sliding rod 14 is connected to a pull rod 16 through a rotating shaft. A fixing piece 15 is fixed on the outer wall of the sliding rod 14. A return spring 17 is also sleeved on the outer wall of the sliding rod 14. The return spring 17 is located between the mounting piece 13 and the fixing piece 15. Limiting grooves 12 for inserting the sliding rod 14 are formed on both of the two limiting pieces 11. Limiting rods 18 are fixed on the outer wall of the top connecting pipe 5 above the two mounting pieces 13 away from each other; during use, when it is necessary to install the top connecting pipe 5, the pull rod 16 can be pulled upward and hung on the limiting rod 18. At this time, the sliding rod 14 will move upward under the drive of the pull rod 16, making the return spring 17 in a compressed state. Then, the top connecting pipe 5 and the bottom connecting pipe 4 are butted. After the installation is completed, the pull rod 16 is released. Under the action of its own elastic force, the return spring 17 will drive the sliding rod 14 to move downward until the sliding rod 14 is inserted into the limiting groove 12. At this time, the connection between the top connecting pipe 5 and the bottom connecting pipe 4 will be more firm and not easy to fall off, improving the stability and sealing performance of the filter during actual use.

[0029] Refer to Figure 4 , positioning pieces 19 are fixed on both of the two limiting rods 18; this can prevent the pull rod 16 from falling off the limiting rod 18.

[0030] Refer to Figure 1 and Figure 2 , a positioning block 2 is further fixed on the top of the hydrogen-oxygen ventilator body 1. An installation groove 3 for inserting the bottom connecting pipe 4 is formed on the positioning block 2, which can facilitate the installation of the bottom connecting pipe 4 on the water filling port of the hydrogen-oxygen ventilator body 1. Clamping screw rods 10 are installed on both sides of the positioning block 2 through threads. One end of each of the two clamping screw rods 10 penetrates through the positioning block 2 and is in close fit with the outer wall of the bottom connecting pipe 4; the bottom connecting pipe 4 can be clamped by rotating the two clamping screw rods 10 clockwise, making it not easy to shake.

[0031] Refer to Figure 4 , the sliding rod 14 is made of metal material; it is not easy to bend or break, extending its service life.

[0032] The implementation principle of a filter for a ventilator that is convenient for cleaning and replacement in an embodiment of the present application is as follows: during use, the materials for filtration can be placed inside the filter element 9, and then the filter element 9 is placed on the sleeve 7. Then, by rotating the top connecting pipe 5 clockwise, it is installed on the bottom connecting pipe 4, making the positioning ring 20 closely fit on the top surface of the filter element 9. At this time, the filter element 9 is firmly clamped between the top connecting pipe 5 and the sleeve 7, forming a stable structure. This design not only ensures the quick replacement of the filter element 9 but also improves the overall sealing performance of the filter;

[0033] It is worth mentioning that the filter of the present application also has excellent cleaning convenience. When the filter element 9 needs to be cleaned, just rotate the top connecting pipe 5 counterclockwise, remove it from the bottom connecting pipe 4, and then the filter element 9 can be easily taken out for cleaning. After cleaning, reinstall it according to the above steps. This design not only simplifies the cleaning process but also improves the service life of the filter;

[0034] The filter for a ventilator that is easy to clean and replace disclosed in the embodiment of the present application, by optimizing the fixing method of the filter element 9, not only realizes the rapid replacement of the filter element 9 but also improves the overall sealing performance and cleaning convenience of the filter. This kind of filter has a wide application prospect in practical applications and can bring a more convenient and efficient use experience to ventilator users.
