DETAILED DESCRIPTION

[0022] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0023] The term "multiple" as used herein refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0024] Figure 1 : is a structural schematic diagram of the HEPA product assembly structure provided in the embodiment of the present application, including a HEPA upper shell 10, a HEPA lower shell 20, and a filter paper 30. The upper and lower shells of HEPA are designed as a rectangular structure as a whole, and the filter paper 30 is placed between the upper and lower shells. A filter cavity 21 that passes through from top to bottom is provided on the HEPA lower shell 20, and the filter paper is provided in the filter cavity 21. The HEPA upper shell 10 is provided on the HEPA lower shell 20 and embedded in the filter cavity 21, and the filter paper 30 is pressed under the HEPA upper shell 10.

[0025] See also Figure 2 , the sizes of the filter chamber 21 and the filter paper 30 match, and both are set to a rectangular structure or a special structure. The filter chamber 21 is located inside the HEPA lower shell 20, and includes an upper bearing frame 211 and a lower bearing frame 212. The plate structure of the upper bearing frame 211 is fixed on the inner wall of the HEPA lower shell 20, and the lower bearing frame 212 is set on the inner wall of the upper bearing frame 211. Of course, in some embodiments, the lower bearing frame 212 can also be set to the lower part of the upper bearing frame 211 and fixed to the inner wall of the HEPA lower shell 20. This premise requires that the thickness of the lower bearing frame 212 is greater than that of the upper bearing frame 211, that is, the plate forms a circle of bearing structure inward to carry the filter paper. The frame plate 22 of the HEPA lower shell 20 is divided into two parts: a rectangular frame plate 221 and an arc frame plate 222. At least three rectangular frame plates 221 and an inwardly concave arc frame plate 222 surround the HEPA lower shell 20. The upper bearing frame 211 has the same height as the concave arc frame plate 222, and the plate surface of the upper bearing frame 211 is tangent to the plate surface of the arc frame plate 222. In some embodiments, the bottom of the concave arc frame plate 222 is higher than the bottom of the rectangular frame plate 221, which can facilitate the overall pulling and pressing of the device.

[0026] See also Figure 3 and Figure 4, an extension end 23 is also provided at the top of the rectangular frame plate 221, and the extension end is slightly protruding, which is convenient for carrying and carrying. In addition, a buckle 26 is also provided at the lower part of the extension end 23. The design of the buckle corresponds to the pressing mold, which is tightly fixed and convenient to take. The height of the arc frame plate 222 is less than the height of the rectangular frame plate 221, and the upper end surface of the arc frame plate 222 is consistent with the upper end surface of the rectangular frame plate 221. A pair of grooves 24 are provided at the connection between the bottom end of the arc frame plate 222 and the rectangular frame plate 221. The grooves 24 are mainly formed by the concave arc frame plate 222 and the rectangular frame plates 221 on both sides and the upper bearing frame 211. Specifically, the arc-shaped frame plate 222 can be designed as a semicircular structure, and its diameter is smaller than the width of the upper supporting frame 211, that is, the width of the filter cavity. In this way, it is necessary to extend the side walls between the semicircular structure and the rectangular frame plates on both sides to connect them. The bottom of the side wall is designed to be rectangular and tangent to the semicircular structure to form a pair of rectangular frames. After a horizontal plate is set in the rectangular frame, a groove is formed. Specifically, the lower groove is a rectangular structure, and the upper groove forms a special-shaped structure, so as to increase the stability of the structure.

[0027] Furthermore, a protrusion 25 is provided on the groove wall of the groove, and the block can be convenient for overall transportation and carrying, or can be matched with an ultrasonic pressing machine for pressing.

[0028] Figure 4 The upper HEPA shell 10 is also designed as a rectangular structure, with a filter through hole 11 on the panel, and a sink 12 surrounding the filter through hole 11 on the lower panel of the upper HEPA shell 10. The sink 12 is consistent with the size of the upper bearing frame 211. In this way, after putting in the filter pool paper, the upper HEPA shell 10 can be directly placed on the upper bearing frame 211, and the sink 12 is embedded in the filter cavity 21 formed by the frame of the upper bearing frame 211 and tightly pressed. Then the whole is put into the ultrasonic pressing machine for pressing, and the complete HEPA product is taken out.

[0029] In summary, the present application adopts a two-part pressing design of a HEPA upper shell and a HEPA lower shell, and the filter paper is placed in the filter cavity of the HEPA lower shell. The filter cavity is surrounded by an upper and lower bearing plate frame, and the lower bearing frame is placed inside the upper bearing frame to form a bottom support, while the HEPA upper shell adopts a groove design to form a buckle plate, which is snapped into the upper bearing plate frame, so as to press the filter paper into the filter cavity. The HEPA assembly and pressing process can directly eliminate the use of adhesives. After the filter paper is placed in the lower shell, it is snapped into the upper shell, and then put into the ultrasonic pressing machine for pressing, and the complete HEPA product is taken out. The whole process eliminates adhesives, reduces resource waste, and is more environmentally friendly. Because no adhesive is needed, there is no need to consider the curing time of the adhesive and the risk of adhesive overflow, which improves production efficiency, reduces product defects, and ensures the beauty of the product.
