[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] like Figures 1 to 2As shown, this embodiment provides a blower, including an outer frame 1, a mesh plate 2, a filter layer 21, an inner frame 3, a side frame 31, a motor 4, a fan blade 5, and an adsorption assembly 6. The outer frame 1 is locked to the mesh plate 2. The filter layer 21 is nested inside the inner end of the mesh plate 2. The motor 4 is mounted outside the inner frame 3. The output end of the motor 4 is rotatably connected to the fan blade 5, which is located inside the inner frame 3. A ventilation hole 32 is provided through the inner frame 3. The side frame 31 is locked to the front end of the inner frame 3. An adsorption assembly 6 is nested on the side frame 31. The adsorption assembly 6 includes a magnet 61 and a mounting plate 62. A plurality of air supply channels 621 are provided through the mounting plate 62. An mounting groove 622 is provided on the mounting plate 62. The mounting groove 622 is located on at least one side of the air supply channel 621. A magnet 61 is installed on the mounting groove 622.

[0019] Furthermore, a mounting plate 62 is nested on the side frame 31, and mounting slots 622 are located on both sides of the air supply duct 621.

[0020] Furthermore, the inner frame 3 is installed inside the outer frame 1 via the support rod 33.

[0021] Furthermore, a first connecting plate 311 is provided on the side frame 31, and a second connecting plate 34 is provided on the inner frame 3. The side frame 31 is fitted and corresponding to the second connecting plate 34 on the inner frame 3 through the first connecting plate 311, and is connected and locked by screws 35.

[0022] Furthermore, the mesh panel 2 is locked to the outer frame 1 by screws.

[0023] Furthermore, the outer frame 1 has an open opening 11 on one side where the side frame 31 is installed.

[0024] The motor 4 is installed outside the inner frame 3 and inside the outer frame 1. Sufficient space is reserved on the side of the motor 4 so that when the motor 4 generates heat, the heat can be quickly transferred to other spaces inside the outer frame 1, which is beneficial to improving the heat dissipation effect of the motor 4. The mesh plate 2 and the filter layer 21 on the mesh plate 2 can isolate impurities in the working environment. Air can pass normally through the mesh holes on the mesh plate 2 and the holes on the filter layer 21. Of course, air can also enter the outer frame 1 from the open port 11 side. When this utility model is in use, the motor 4 drives the fan blade 5 to rotate. The fan blade 5 generates airflow as it rotates at a continuous high speed. The airflow contains metal debris and is sent through the air supply channel 621. Since multiple independent air supply channels 621 are provided, each air supply channel 621 is equipped with a magnet 61 for adsorbing metal debris. The airflow is dispersed into multiple air supply channels 621. When passing through the magnetic field range of the corresponding magnet 61, the metal debris will be adsorbed on the surface of the magnet 61. The cooperation of multiple magnets 61 is beneficial to improving the adsorption effect.
