Description

Technical Field

[0001] The utility model relates to the technical field of hot air blower equipment, in particular to a hot air blower based on a high-frequency electromagnetic structure. Background Art

[0002] High-frequency electromagnetic fan is a fan device driven by high-frequency electromagnetic force. High-frequency electromagnetic fan has significant advantages in energy saving, high efficiency, precise control, environmental protection and quietness, and has gradually been applied and promoted in various fields.

[0003] At present, when a high-frequency electromagnetic fan is used to dry materials, a heating mechanism for heating air is installed at the air outlet of the high-frequency electromagnetic fan, so that the high-frequency electromagnetic fan generates hot air when working, so as to improve the drying efficiency of the materials; and, the air inlet of the existing high-frequency electromagnetic fan is mostly equipped with a filter. When the high-frequency electromagnetic fan is working, the dust in the air is filtered through the filter to prevent the dust from entering the high-frequency electromagnetic fan. After long-term use, a large amount of dust is attached to the high-frequency electromagnetic fan, which affects the normal operation of the high-frequency electromagnetic fan; however, in actual use, there are still the following defects:

[0004] When the high-frequency electromagnetic fan is working, the filter filters the dust in the air to prevent the dust from entering the high-frequency electromagnetic fan. However, when the filter filters the dust in the air, the dust will adhere to the surface of the filter. The accumulation of dust will increase the resistance of the air passing through the filter, thereby increasing the energy consumption and load of the high-frequency electromagnetic fan, thereby reducing the service life of the high-frequency electromagnetic fan.

[0005] Therefore, the present application proposes a hot air blower based on a high-frequency electromagnetic structure. Utility Model Content

During this period, the air contacts the filter plate 52. After the filter plate 52 filters the dust in the air, the gas passes through the filter plate 52 and then enters the air inlet pipe 22. The filter plate 52 can achieve the effect of filtering the dust in the air. , the dust generated by filtration will adhere to the side wall of the filter plate 52, and when the fan body 2 is working, when the gas enters the air inlet pipe 51, it contacts the impeller 63, so that the impeller 63 can rotate around the rotating shaft 61 in the air inlet pipe 51, thereby driving the brush 62 to rotate around the rotating shaft 61, and the brush 62 contacts the side wall of the filter plate 52, so as to clean the dust attached to the side wall of the filter plate 52, effectively avoiding the situation where dust accumulates on the surface of the filter plate 52 and increases the resistance of air passing through the filter plate 52, thereby reducing the energy consumption and load of the fan body 2 under long-term operation, and improving the service life of the fan body 2;

[0043] When the electric heating plate 41 is damaged and needs to be repaired and replaced, the cover plate 32 can be removed by removing the screws. The electric heating plate 41 is fixedly installed at the bottom of the cover plate 32, so that the electric heating plate 41 can be removed from the connecting shell 3, which is convenient for repair and replacement of the electric heating plate 41; when the brush 62 is disassembled and replaced, the screws used to fix the connecting plate 611 and the brush 62 can be removed, and the fixation between the connecting plate 611 and the brush 62 can be cancelled, and the brush 62 can be disassembled, thereby facilitating the disassembly and replacement of the brush 62; through the design of the slot 53, when the filter plate 52 is installed, the filter plate 52 is inserted into the installation shell 5 along the slot 53, and the installation of the filter plate 52 can be completed, and the operation is simple. On the contrary, the filter plate 52 can be pulled out from the slot 53 to complete the disassembly of the filter plate 52, which is convenient for the disassembly and replacement of the filter plate 52; through the design of the blocking cover 54, it is realized The slot 53 is blocked by the design of the discharge port 55 and the blocking plate 56. When the fan body 2 is working, the impeller 63 causes the brush 62 to rotate around the rotating shaft 61 to clean the dust attached to the side wall of the filter plate 52. The dust cleaned by the brush 62 on the side wall of the filter plate 52 remains in the mounting shell 5 and is located on the side of the slot 53 away from the air inlet pipe 22, and falls to the bottom wall of the mounting shell 5 under the action of the dust itself. At this time, the fixation between the two pairs of blocking plates 56 and the mounting shell 5 is cancelled, so that the dust on the bottom wall of the mounting shell 5 can be discharged through the discharge port 55, which is convenient for cleaning the dust remaining in the mounting shell 5. Through the design of the grille plate 7, when the fan body 2 is working, when the external air flows into the air inlet pipe 51, the external air enters the air inlet pipe 51 through the grille holes, effectively preventing the paper from flying into the air inlet pipe 51 with the air flow and thus adhering to the impeller 63.
