[0017] The utility model is described in detail below in combination with the drawings.

[0018] As Figs. 1-2 shown, the utility model discloses a filter of side glue coating, including core 3, set up in the top cover 1 and bottom cover 2 of core 3 and set up in the first glue coating line 31 and second glue coating line 32 of core 3, the core 3 is provided with a plurality of pleat parts 33, and the plurality of pleat parts 33 are connected head to tail and are arranged around the circumference of the top cover 1 and bottom cover 2, and the first glue coating line 31 and second glue coating line 32 are arranged on the two sides of the pleat part 33 respectively.

[0019] The top cover 1 and the bottom cover 2 are respectively connected to the top and the bottom of the core 3, and the installation and removal are simple, the core 3 is convenient to replace and use, the core 3 is formed into a hollow column shape by a plurality of pleats 33 connected end to end, which is beneficial to the core 3 being arranged around the circumference of the top cover 1 and the bottom cover 2, the first glue line 31 and the second glue line 32 are respectively arranged on the two sides of the pleat 33, which can effectively fix the spacing between the two adjacent pleats 33, avoid the situation that the two adjacent pleats 33 are adhered and cannot be separated, thereby ensuring that the air can normally flow in and out of the core 3, ensuring that the core 3 can also ensure the working stability under the condition of high flow, reducing the possibility of structural damage between the pleats under high flow, specifically, the first glue line 31 and the second glue line 32 are specifically hot melt glue, and are respectively coated on the two side outer walls of the pleat 33, in addition, the first glue line 31 or the second glue line 32 can also be coated on one side outer wall of the pleat 33, that is, the purpose of one-side coating and double-side coating can be achieved, effectively avoiding the situation that the structure is cracked at the corner position of the pleat 33, improving the structural stability and air flow, thereby reducing the manufacturing cost and improving the filtering and purifying performance. In addition, the length of the pleat 33 is 31mm, and the length of the first glue line 31 and the second glue line 32 is 10mm to 20mm. The structure of the utility model has high stability, increases the spacing between the pleats, accelerates the air flow, and improves the filtering effect.

[0020] The outer side of the top cover 1 of the embodiment is provided with a first handle strip 11, and the outer side of the bottom cover 2 is provided with a second handle strip 21. Specifically, the first handle strip 11 is used to separate and pull out the top cover 1 from the core 3, which is convenient for the convenient disassembly between the top cover 1 and the core 3, and the second handle strip 21 is used to separate and pull out the bottom cover 2 from the core 3, which is convenient for the convenient disassembly between the bottom cover 2 and the core 3.

[0021] The top cover 1 of the embodiment is provided with a first accommodating groove 12, the first accommodating groove 12 is recessed from the outer wall of the top cover 1, the bottom cover 2 is provided with a second accommodating groove 22, the second accommodating groove 22 is recessed from the outer wall of the bottom cover 2, and the top and bottom of the core 3 are respectively accommodated in the first accommodating groove 12 and the second accommodating groove 22. Specifically, the top of the core 3 is inserted and accommodated in the first accommodating groove 12, the bottom of the core 3 is inserted and accommodated in the second accommodating groove 22, and then the installation and removal between the top cover 1, the bottom cover 2 and the core 3 are realized, which is simple and convenient to operate and has high connection stability.

[0022] The central axes of the top cover 1, the bottom cover 2 and the core 3 of the embodiment coincide. Specifically, the central axes of the top cover 1, the bottom cover 2 and the core 3 coincide, which ensures the accuracy and coaxiality of the positions of the components, realizes the accurate alignment between the top cover 1, the bottom cover 2 and the core 3, and then the top cover 1, the bottom cover 2 and the core 3 can be connected and fixed together, thereby improving the assembly efficiency.

[0023] The core 3 of the embodiment is made of absorbent fiber material. Specifically, the core 3 is made of absorbent fiber material. Because the surface of the absorbent fiber is rough, there are many micropores with permeability and migration in the inside, so it can absorb gas and get the name, has good air permeability and fast drying, and helps better circulation of air and moisture.

[0024] The above is only the preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation and application range will be changed, and the content of the specification should not be understood as the limitation of the present application.
