[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-8The present invention provides an embodiment of a waterproof air filter, comprising a housing 1, a top cover 2, and a filter body 5. The filter body 5 is disposed inside the housing 1 via a guide positioning component 7. A sealing component 6 is disposed between the top of the housing 1 and the bottom of the top cover 2. A waterproof layer 102 is disposed on the inner side of the housing 1. An air inlet pipe 3 is connected to the top of the top cover 2, and an air outlet pipe 4 is connected to the outer side of the housing 1.

[0037] Specifically, the design of the waterproof layer 102 and the sealing component 6, combined with the cooperation of the outer shell 1 and the top cover 2, effectively prevents external moisture from entering the filter body 5, ensuring that the filter can still operate stably and is unaffected by moisture even in humid environments. The waterproof layer 102 provides long-term protection for the filter body 5, extending its service life. The cooperation between the guide positioning component 7 and the filter body 5 ensures that the filter can be securely installed between the outer shell 1 and the top cover 2, avoiding deviations during installation and making the equipment more stable. The design of the air inlet pipe 3 and the air outlet pipe 4 ensures that air can smoothly enter and exit the filter body 5, thereby ensuring efficient air filtration and ensuring optimal air purification. The overall design makes the filter more reliable and durable in complex environments.

[0038] Reference Figure 2 and Figure 3 The filter body 5 includes an interception layer 501, which is the outermost layer of the filter body 5. A first filter layer 502 is disposed on the outer side of the interception layer 501. A second filter layer 503 is disposed on the outer side of the first filter layer 502. An isolation layer 504 is disposed on the outer side of the second filter layer 503. An adsorption layer 505 is disposed on the outer side of the isolation layer 504.

[0039] Specifically, through the multiple designs of the interception layer 501, filter layer one 502, and filter layer two 503, combined with the cooperation of the isolation layer 504 and the adsorption layer 505, the filter body 5 can efficiently remove various pollutants from the air layer by layer. The interception layer 501 is responsible for intercepting larger particles, protecting subsequent filter layers from clogging. Filter layers one 502 and filter layer two 503 gradually filter out finer particles, ensuring increasingly pure air. The isolation layer 504 effectively isolates the filtered impurities, preventing them from returning to clean air. Finally, the adsorption layer 505 adsorbs harmful gases and tiny particles from the air, ensuring fresher and harmless air. The overall design achieves comprehensive and efficient air filtration, effectively removing everything from large particles to tiny pollutants, providing a clean and healthy air environment.

[0040] Reference Figure 1 , Figure 5 and Figure 6An upward flange 201 is fixedly connected to the bottom edge of the upper cover 2, and a downward flange 101 is fixedly connected to the top edge of the outer shell 1. The downward flange 101 and the upward flange 201 are connected by multiple bolts. The sealing assembly 6 includes a sealing gasket 601 and a sealing groove 602. The sealing gasket 601 is located at the bottom of the upper cover 2, and the sealing groove 602 is located at the top of the outer shell 1. The sealing gasket 601 and the sealing groove 602 are in a sealing fit.

[0041] Specifically, the design of the upper flange 201 and the lower flange 101, combined with the bolt connection, ensures a firm connection between the upper cover 2 and the outer casing 1, preventing loosening due to vibration or external force. The sealing fit between the sealing gasket 601 and the sealing groove 602 makes the sealing effect more tight, preventing external moisture or contaminants from penetrating into the filter body 5. The use of the sealing assembly 6 effectively prevents the entry of external moisture. The overall design provides better waterproofing, extends the service life of the equipment, and improves air filtration efficiency.

[0042] Reference Figure 7 and Figure 8 The guide positioning component 7 includes two sets of guide plates 701, which are fixedly connected to the upper and lower ends of the filter body 5 respectively. There are multiple guide plates 701. Multiple guide grooves 702 are provided on the inner side of the outer shell 1. The guide plates 701 and guide grooves 702 are inserted and engaged. A positioning component is provided at the bottom of the filter body 5. The positioning component is used to position the filter body 5 inside the outer shell 1. The positioning component includes a positioning disk 703, which is fixedly connected to the bottom of the filter body 5. A positioning groove 704 is opened on the inner bottom wall of the outer shell 1. The positioning disk 703 and positioning groove 704 are inserted and engaged.

[0043] Specifically, through the interlocking of guide plate 701 and guide groove 702, multiple positions of guide plate 701 guide the filter body 5 accurately into the housing 1, ensuring that the filter body 5 does not deviate during installation, thus avoiding installation errors or instability. The positioning assembly, including the cooperation of positioning disc 703 and positioning groove 704, allows the filter body 5 to be firmly positioned inside the housing 1, further reducing the possibility of displacement and ensuring that the filter body 5 remains stable during use. This design not only simplifies the installation process but also greatly improves the working stability and durability of the filter, ensuring its long-term efficient operation.

[0044] Working principle: When installing the filter body 5, guide plates 701 are provided at both the top and bottom ends of the filter body 5, and there are many guide plates 701. At the same time, multiple guide grooves 702 are provided on the inner side of the outer shell 1. During installation, the filter body 5 is positioned in accordance with the position of the outer shell 1, and the guide plates 701 at both the top and bottom ends of the filter body 5 are aligned with the guide grooves 702 on the inner side of the outer shell 1. Since the guide plates 701 and the guide grooves 702 are interlocked, the guide plates 701 are slowly inserted into the guide grooves 702 in this direction. In this way, during the insertion process, the cooperation between the guide plates 701 and the guide grooves 702 guides the filter body 5 to accurately enter the interior of the outer shell 1, which plays a role in positioning and guiding, so that the installation position will not be deviated and the installation position can be easily found accurately.

[0045] After the guide plate 701 is fully inserted into the guide groove 702, the filter body 5 is basically inside the housing 1 at a suitable depth. Continue to slowly move the filter body 5 downwards so that the positioning plate 703 is aligned with the positioning groove 704. Then, insert the positioning plate 703 into the positioning groove 704. The insertion and engagement of the positioning plate 703 and the positioning groove 704 can further fix the position of the filter body 5 inside the housing 1, so that it is firmly fixed at the bottom without shaking or shifting, ensuring that the filter body 5 operates stably in subsequent filtration operations.

[0046] Then, the sealing gasket 601 at the bottom of the top cover 2 is inserted into the sealing groove 602 at the top of the outer casing 1. The sealing gasket 601 and the sealing groove 602 are sealed together, which can prevent water from entering the filter body 5 in all directions, avoid the filter being damaged by water, and extend the service life of the filter body 5. Then, the upper flange 201 and the lower flange 101 are fixed by multiple bolts.

[0047] When air needs to be filtered, it first enters the upper cover 2 through the air inlet duct 3. Because there is a waterproof layer 102 on the inside of the outer shell 1 and a sealing component 6 between the upper cover 2 and the outer shell 1, it can effectively prevent external water from entering the filter body 5. The air then comes to the filter body 5 and passes through the interception layer 501, which intercepts some larger impurities. Next, the air passes through the first filter layer 502 and the second filter layer 503, which further filter out smaller impurities. Then, the air passes through the isolation layer 504, which isolates the previously filtered impurities in a certain area, preventing them from returning to the clean air. Finally, the air passes through the adsorption layer 505, which adsorbs some residual harmful gases or tiny particles in the air, making the filtered air purer. The clean air filtered layer by layer by the filter body 5 is then discharged from the air outlet duct 4.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
