TECHNICAL FIELD

[0001] The utility model relates to the field of cleaning appliances, especially to a household mite-removing dust suction head. BACKGROUND

[0002] Mites are microorganisms that are difficult to be detected by naked eyes and widely exist in our daily life. The body size of mites is usually about 0.5 millimeter, and some species are as small as 0.1 millimeter. Mites are quite harmful, and their corpses, secretions and excretions can all become allergens. Therefore, mite-removing brushes are commonly used to remove mites in life. The existing mite-removing brushes are generally connected with a dust collector, and the suction force of the dust collector sucks mites and other sundries in the environment into the dust collector. However, since the cleaning objects of the mite-removing brush are usually dust particles on flexible surfaces such as beds, mattresses and sofas, the cleaning effect is poor due to unstable suction force.

[0005] The further improved scheme in the above-mentioned technical scheme is as follows:

[0006] 1. In the above-mentioned scheme, the upper opening is a waist-shaped hole, the short diameter of the waist-shaped hole is the same as the inner diameter of the circular air inlet, and the long diameter is greater than the inner diameter of the air inlet.

[0007] 2. In the above-mentioned scheme, the outer wall of the sleeve and the inner wall of the shell are connected through at least one set of circumferentially extending guide strips and guide grooves.

[0008] 3. The above scheme, formed in the lower opening long edge of the flange strip is provided with at least 2 interval distribution groove.

[0009] 4. The above scheme, the drive assembly is installed in the shell through a support frame and is in transmission connection with one end of the rolling brush.

[0010] 5. The above scheme, the drive assembly further comprises: the motor installed on one side of the support frame, the driving wheel installed on the output shaft of the motor and located on the other side of the support frame, and the driven wheel connected with the driving wheel through a belt, one end of the rotating shaft installed on the support frame through a bearing is connected with the driven wheel, and the other end of the rotating shaft is connected with the rolling brush.
