Description

Technical Field

[0001] The utility model relates to the technical field of air purifiers, in particular to an air filter element structure that is convenient for disassembly and assembly. Background Art

[0002] There are many brands of air purifiers on the market. Among them, the vertical air purifier is commonly used at home. The filter element of the vertical air purifier is on the back side. After opening the back cover, the internal filter element can be taken out. The filter element is divided into a variety of scents, including aromatherapy filter elements. The air purified by the aromatherapy filter element has a fragrance.

[0003] However, the filter element needs to be cleaned after long-term use. When disassembling, you need to press the upper filter frame with your hand and press down continuously to deform the traditional straight filter before you can take out the filter element. When installing, you need to press the straight filter to deform it so that it can be installed conveniently. This will not only damage the filter, but long-term use of the filter will cause a gap at the connection between the filter and the purifier. The gap comes from the deformed filter element, which greatly reduces the air purification effect.

[0004] In order to solve the above problems, the present application proposes an air filter element structure that is convenient for disassembly and assembly. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 A convenient disassembly and assembly air filter element structure includes a filter frame 1, the lower end of the filter frame 1 is fixedly connected to a straight filter screen 2, an elastic filter element is arranged between the upper and lower straight filter screens 2, the lower end edge of the filter frame 1 is fixedly connected to a connecting plate 6, the lower end of the connecting plate 6 is fixedly connected to an auxiliary part, and the distance between the upper and lower auxiliary parts is set to eight centimeters.

[0021] Specific working principle and implementation method: a straight filter screen 2 is fixed at the lower end of the filter frame 1. The traditional whole is all straight filter screens 2. When taking the whole out of the air purifier, it is necessary to press the filter frame 1 at the upper end. When installing, it is also necessary to press the filter frame 1 downward and then insert it into the air purifier. Through this design, a good elastic effect can be achieved through the elastic filter element, and a larger filtration area can be achieved through the elastic filter element, and a better pressing effect can be achieved through the auxiliary parts on both sides of the lower end of the filter frame 1; the advantage of such a design is that no matter when the user is installing or disassembling the whole, the auxiliary parts can conveniently press the whole in the limited space of the air purifier, thereby achieving efficient installation and disassembly effects, and a larger filtration area can be achieved through the elastic filter element, so that the filtering effect is better.

[0022] like Figure 3 As shown, the elastic filter element includes a folded filter screen 3, which is arranged in an accordion tube style. The upper and lower ends of the inner side of the folded filter screen 3 are fixedly connected with elastic support sheets 5. The number of elastic support sheets 5 is set in multiples and the spacing is set equally. When the folded filter screen 3 is squeezed by the upper end, the elastic support sheet 5 will be squeezed first. After the elastic support sheet 5 is compressed, it will drive the folded filter screen 3 to fold, so that the overall length can be contracted, and the whole can be quickly taken out for replacement. When installing, the overall length is also reduced to achieve a better installation effect.

[0023] like Figure 3 As shown, the auxiliary part includes a vertical rod 7, the lower end of which is fixedly connected with a fastener 8, and the lower end of the fastener 8 is arc-shaped. When using the auxiliary part, the fastener 8 close to the upper and lower ends can be pressed by one hand with both hands, so that the vertical rod 7 can be driven by the fastener 8, and the vertical rod 7 pulls the connecting plate 6, which drives the filter frame 1 at the upper end to squeeze the folded filter screen 3 at the lower end through the connecting plate 6. This is convenient to operate, and it saves effort and does not hurt the hands.

[0024] like Figure 3 As shown, a fixing ring 9 is fixedly connected to the vertical rod 7, and the lower end surface of the fixing ring 9 is flush with the lower end surface of the straight filter screen 2. The fixing ring 9 can stabilize the vertical rod 7. When the user presses up and down during use, the vertical rod 7 tends to tilt and exert force. The fixing ring 9 can achieve a stable and balanced effect. The fixing ring 9 can ensure that the entire rod will not be squeezed and damaged during transportation, thereby further protecting the straight filter screen 2.

[0025] like Figure 1 As shown, a sealing ring 4 is fixedly connected to the upper end surface of the filter frame 1. The sealing ring 4 is designed to be tightly connected to the output end of the air purifier under the action of the elastic support sheet 5, so as to achieve a better filtering effect.

[0026] like Figure 3 As shown, the upper and lower ends of the folded filter 3 are threadedly connected to the straight filter 2 at the upper and lower ends. The upper and lower ends of the folded filter 3 are both threaded sleeves, and the connection ends of the upper and lower ends to the straight filter 2 are both threaded heads. In this way, the folded filter 3 can be disassembled, which is convenient for users to clean the interior regularly, thereby achieving better use effect.

[0027] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
