Description

Technical Field

[0001] This utility model relates to the field of air curtain machine technology, specifically to a bottom-drawing filter screen and an air curtain machine. Background Technology

[0002] Currently, air curtain machines are used to create a downward airflow at doorways. In actual use, air curtain machines require frequent cleaning and replacement of the filters installed inside the air inlet to ensure hygiene. However, the filters used in existing air curtain machines are fixed to the machine casing with bolts through a mounting plate. With this connection method, when cleaning or replacing the filter, workers must first remove the bolts with a screwdriver before they can remove the filter, making the disassembly and installation of the filter too complicated and inconvenient. Therefore, the applicant hereby proposes a bottom-drawing filter and air curtain machine to solve the aforementioned problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a bottom-drawing filter screen and an air curtain machine.

[0004] The technical solution of this utility model is as follows: This utility model provides a pull-out filter screen, including a frame, a filter screen, a buckle part, and a locking groove; the filter screen is provided inside the frame, and buckle parts are respectively provided on both sides of the bottom of the frame, and a locking groove is vertically opened between the buckle part and the frame.

[0005] Furthermore, the upper end of the buckle is triangular, and the lower end is vertical.

[0006] Furthermore, it also includes the skeleton set within the frame.

[0007] Furthermore, the skeleton is cross-shaped.

[0008] Furthermore, it also includes a pull-out section, which is provided on the bottom of the frame along its length.

[0009] Furthermore, the filter screen is a nylon mesh.

[0010] Furthermore, the frame, buckle, skeleton, and pull-out part are all made of plastic.

[0011] This utility model also provides an air curtain machine, including a body and the above-mentioned pull-out filter screen. The bottom of the body has a vertically opened air outlet, and the pull-out filter screen is clipped into the air outlet.

[0012] The beneficial effects achieved by this utility model are as follows: The present invention provides a pull-out filter screen and air curtain machine, which, through the cooperation of the buckle part, locking groove and pull-out part, can realize the function of quick installation and disassembly of the pull-out filter screen, improve the installation or disassembly efficiency while ensuring installation stability, and can complete the installation or disassembly without the aid of other tools, thus improving convenience.

[0017] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are clearly described below with reference to the accompanying drawings. Obviously, the specific embodiments described are merely preferred embodiments of this utility model, and not all embodiments.

[0018] like Figure 1-4 As shown, the present invention provides a pull-out filter screen, which is applied to an air curtain machine to filter airflow; it includes a frame 1, a filter screen 2, a buckle part 3, and a locking groove 4; the filter screen 2 is provided inside the frame 1, and the buckle part 3 is provided on both sides of the bottom of the frame 1. A locking groove 4 is vertically opened between the buckle part 3 and the frame 1. The upper end of the buckle part 3 is triangular and the lower end is vertical strip-shaped; through the cooperation of the buckle part, the locking groove, and the pull-out part, the pull-out filter screen can be quickly installed and removed, which improves the installation or removal efficiency while ensuring the installation stability. Installation or removal can be completed without the aid of other tools, thus improving convenience.

[0019] It also includes a skeleton 5 set inside the frame 1. In this embodiment, the skeleton 5 is preferably cross-shaped, but it can also be grid-shaped, etc.; it is used to strengthen the connection stability between the frame 1 and the filter screen 2.

[0020] It also includes a pull-out section 6, which is provided on the bottom of the frame 1 along its length direction; this makes it easier for staff to grab and pull out the frame 1.

[0021] In this embodiment, the filter screen 2 is preferably a nylon mesh, but it can also be a non-woven fabric, etc. The frame 1, buckle 3, skeleton 5, and pull-out part 6 are all made of plastic, reducing the overall weight of the filter.

[0022] This utility model also provides an air curtain machine, including a body 10 and the aforementioned pull-out filter screen. The bottom of the body 10 has a vertically opened air outlet 101, and the pull-out filter screen is clipped into the air outlet 101; this facilitates the quick installation or removal of the pull-out filter screen by the staff.

[0023] During actual installation, the staff holds the frame and inserts it directly into the air outlet. The two sides of the air outlet will press the corresponding buckles on the frame. Guided by the upper triangular part, the buckles will deform slightly into the locking groove, allowing them to smoothly enter the air outlet. After the buckles enter the air outlet, the pressure will disappear, and the buckles will spring back and reset, making them engage with the inner wall of the air outlet. This will quickly complete the installation of the pull-out filter. During actual disassembly, the staff presses the lower end of the buckle on both sides of the frame with both hands, causing the whole frame to deform slightly into the locking groove, releasing the upper end of the buckle from the inner wall of the air outlet and pulling it downward slightly. Then, the staff holds the pull-out part and pulls the whole frame out of the air outlet, thus quickly completing the disassembly of the pull-out filter.

[0024] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
