Embodiment 1

[0049] This embodiment provides a kind of circulation fan, in one embodiment, such as Figure 1 to Figure 12As shown, the circulation fan includes an air duct structure 1, a rear screen 4, and a filter screen 3. Of course, the circulation fan also includes structures such as a front screen and a motor.

[0050] The rear net 4 is connected to the air duct structure 1 ; the filter screen 3 is arranged between the air duct structure 1 and the rear net 4 .

[0051] The circulation fan provided in this embodiment is provided with a filter screen 3 between the rear screen 4 and the air duct structure 1, and when the air enters the air duct structure 1 through the rear screen 4, the filter screen 3 filters the air to purify the air. At the same time, it can prevent dust and bacteria from adhering to the fan blades and other structures in the air duct structure 1, so as to ensure the quality of the air supply, thereby ensuring the indoor air quality and the health of users.

Abstract

The invention relates to the technical field of household appliances, and particularly relates to a circulating fan. The circulating fan comprises an air duct structure, a rear net and a filter screen, wherein the rear net is connected with the air duct structure, and the filter screen is arranged between the air duct structure and the rear net. The filter screen is arranged between the rear net and the air duct structure, when air enters the air duct structure through the rear net, the filter screen filters the air, and the air purification effect is achieved; and meanwhile, dust and bacteriacan be prevented from adhering to fan blades and other structures in the air duct structure, the air supply quality is guaranteed, and therefore the indoor air quality and the body health of a user are guaranteed.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a circulation fan. Background technique [0002] The main function of the circulation fan is to form a convective circulation of the indoor air, and achieve the effect of balancing the temperature with a reasonable air flow direction. At present, the structure of the head of the circulating fan is relatively complicated, and the fixing method of buckle and screw is basically used. It is difficult for the user to disassemble or the disassembly process is cumbersome, resulting in problems such as dust and bacteria accumulation on the structure of the head after long-term use, which affects the quality of the air supply and thus Affect indoor air quality and user's health. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the circulation fan in the prior art affects the quality of ...
