[0029] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below by combining with the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0030] Referring to Figures 1-8The brake structure 100 of the air drum is provided with the filter screen cover 12, the driving assembly 30 and the brake assembly 40, and the filter screen cover 12 is detachably installed on the rear shell 11, the driving assembly 30 is used for driving the air drum assembly 20 to rotate, and the brake assembly 40 is used for stopping the air drum assembly 20 to rotate.

[0031] As shown in Figure 1 , Figure 3 and Figure 5 , in the embodiment provided by the utility model, the brake assembly 40 further includes a spring 43 used for elastically installing the brake connecting rod 41 on the shell, the brake connecting rod 41 includes a stop section 411 used for installing the stop rubber 42 and an abutting section 412 used for abutting with the filter screen cover 12. The spring 43 is installed on the top of the abutting section 412, and the stop section 411 is vertically arranged with the abutting section 412. By installing the spring 43 on the top of the abutting section 412 and vertically arranging the stop section 411 with the abutting section 412, when the filter screen cover 12 is installed on the rear shell 11, the stop protrusion 121 arranged on the filter screen cover 12 and used for embedding in the brake connecting rod 41 is embedded in the abutting section 412 of the brake connecting rod 41, and the brake connecting rod 41 is lifted up, so that the stop rubber 42 is separated from the air drum 21, thereby enabling the driving assembly 30 to drive the air drum assembly 20 to rotate in the rear shell 11. Figure 6As shown, when the filter screen cover 12 is removed, the brake connecting rod 41 drives the stop rubber 42 in the stop section 411 to abut against the air drum assembly 20 under the elastic force of the spring 43, so that the air drum assembly 20 is stopped from rotating in a very short time under the friction force of the stop rubber 42, eliminating the inertia effect of the driving assembly 30 driving the air drum 21 to rotate, thereby effectively improving the safety of the user cleaning the air drum.

[0032] As shown in Figure 1 and Figure 4 , the air drum assembly 20 comprises an air drum 21, an air drum support 22 for mounting the air drum 21 on the rear shell 11, and an air duct 23 arranged at the bottom of the air drum support 22. By mounting the air drum 21 on the rear shell 11 by means of the air drum support 22, the stability of the air drum 21 mounted on the rear shell 11 can be effectively improved, and by arranging the air duct 23 at the bottom of the air drum support 22, the air blown by the driving assembly 30 driving the air drum 21 to rotate in the rear shell 11 can be effectively guided, improving the user's experience during use. In the embodiments provided by the present application, the air drum support 22 is provided with a positioning groove 221 for embedding the stop section 411 of the brake connecting rod 41. By embedding the stop section 411 of the brake connecting rod 41 in the positioning groove 221, the positioning accuracy between the brake connecting rod 41 and the air drum support 22 can be effectively improved, thereby ensuring the positioning accuracy of the stop rubber 42 abutting against the air drum 21 under the elastic force of the spring 43, thereby effectively ensuring the braking effect of the brake assembly 40 eliminating the inertia effect of the air drum and stopping the rotation.

[0033] As shown in Figures 1-3 , in the embodiments provided by the present application, the driving assembly 30 comprises a motor 31 for driving the air drum 21 to rotate, a control switch 32 for controlling the motor 31, and a switch pressing piece 33 for mounting the control switch 32 on the rear shell 11. By mounting the control switch 32 on the rear shell 11 by means of the switch pressing piece 33, the stability of the control switch 32 mounted on the rear shell 11 can be effectively improved. In this embodiment, the air drum 21 is drivingly connected to the output shaft of the motor 31 through locking leaves, and by drivingly connecting the air drum 21 to the output shaft of the motor 31 through the locking leaves, the stability of the driving connection between the air drum 21 and the output shaft of the motor 31 can be effectively ensured, thereby effectively ensuring the stability of the motor 31 driving the air drum 21 to rotate in the rear shell 11, improving the user's experience during use.

[0034] As shown in Figure 7And as shown in 8, the control switch 32 is provided with a first control protrusion 321, the filter cover 12 is provided with a second control protrusion 122, the filter cover 12 is installed on the rear shell 11, and the second control protrusion 122 abuts against the first control protrusion 321 of the control switch 32. When the filter cover 12 is installed on the rear shell 11, the second control protrusion 122 on the filter cover 12 abuts against the first control protrusion 321 of the control switch 32, so that the first control protrusion 321 of the control switch 32 is retracted and closed. At this time, the motor 31 drives the air drum 21 to rotate in the rear shell 11, and because the filter cover 12 is installed on the rear shell 11, the stop protrusion 121 provided on the filter cover 12 for embedding in the brake connecting rod 41 is embedded in the abutting section 412 of the brake connecting rod 41, and the brake connecting rod 41 is lifted up, so that the stop rubber 42 is separated from the air drum 21, so that the motor 31 can drive the air drum 21 to rotate in the rear shell 11; when the filter cover 12 is removed from the rear shell 11, the second control protrusion 122 on the filter cover 12 is separated from the first control protrusion 321 of the control switch 32, so that the first control protrusion 321 of the control switch 32 is popped up and opened. At this time, the motor 31 stops driving the air drum 21 to rotate in the rear shell 11, and the brake connecting rod 41 moves the stop rubber 42 in the stop section 411 and abuts against the air drum assembly 20 under the elastic force of the spring 43, so that the air drum 21 is stopped rotating under the friction force of the stop rubber 42 in a very short time, thereby effectively improving the safety of the user cleaning the air drum.

[0035] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
