According to the brush head of the vacuum cleaner provided by the utility model, during the cleaning process, the front wiper plate and the rear wiper plate reciprocate in opposite directions. Compared with the cylindrical bristles in traditional vacuum cleaners, the wiper plate can have a larger cleaning area due to the back and forth movement of the wiper plate, and can even extend from the left edge to the right edge of the bottom of the brush head body. Due to the larger cleaning area, It can significantly improve the vacuum cleaning efficiency. Moreover, since the front wiper plate and the rear wiper plate reciprocate in opposite directions, the cleaning effect of reciprocating wiping is significantly improved compared with the unidirectional rotary wiping performed by the cylindrical bristles in the conventional vacuum cleaner. Moreover, since the ground is no longer wiped by rolling and wiping, the problem of entanglement of the cylindrical bristles in the prior art is overcome. Moreover, compared with the cylindrical bristles, in this solution, the rag and the ground itself can have a greater force, which is convenient for cleaning the garbage firmly adhered to the ground.

On the other hand, since the front wiper plate is provided with dust-passing holes penetrating the upper and lower ends thereof, the dust suction port remains overlapped with the dust-passing holes. As a result, when the negative pressure generating device is activated, when the garbage enters the dust collecting tank of the front wiper, most of the garbage can be sucked away through the dust suction port without contacting the rag on the front wiper, and the remaining garbage on the ground will be sucked away. The remaining ash that has not been cleaned is disposed of by the rags on the subsequent front board and rear wiper. In addition, the rag on the front wiping plate can push the garbage with larger size and weight forward to the area where the dust suction port is located, and then inhale from the dust suction port. Compared with the combination of the roller brush and the vacuum port, the cylindrical bristles and the vacuum port in the prior art, which work independently or have poor linkage, the The utility model has significant technical progress, and the significantly improved vacuuming and cleaning effect brought about by this linkage is unpredictable in the prior art.

The brush head of the vacuum cleaner can also closely contact the ground without the user pressing hard. On the other hand, the friction between the rag and the ground is significantly enhanced, and the firmly bonded garbage on the ground can be removed, which cannot be achieved by the existing technology. , thus a significant improvement.

Further, the front wiper plate is provided with dust-passing holes through its upper and lower ends, which can also significantly reduce the space occupied by the dust suction port on the bottom of the brush head body, thus increasing the area ratio of the rag on the wiper plate at the bottom of the brush head body.

Further, since the water spray port of the water spray assembly is arranged at the bottom of the brush head body and between the front wiper plate and the rear wiper plate. Therefore, during the process of the brush head, the front wiper contacts the dry ground, and the rear wiper contacts the wet ground, so that the front wiper can dry the surface to be cleaned, so as to clean the dust and other garbage, and the rear wiper can clean the surface to be cleaned. Compared with the simple dry wiping or the simple wet wiping in the prior art, the wet wiping can take into account the processing of various types of garbage and achieve a better comprehensive cleaning effect. As a result, the multi-integrated cleaning functions of vacuuming, dry wiping, and wet wiping are realized, and the vacuuming and cleaning effects are further significantly improved.

Furthermore, since the water jet is arranged between the front wiper and the rear wiper, the dust suction port and the water jet are separated by the rag on the front plate, preventing the cleaning liquid from the water jet from entering the suction. The possibility of the dust port prevents the motor of the vacuum system from being damaged by water ingress, that is, the ingenious structure achieves the improvement of the cleaning effect and the improvement of safety at the same time.

To sum up, the utility model can play the technical effect of significantly improving the cleaning area and cleaning effect of the brush head of the vacuum cleaner, and has outstanding substantive features and remarkable progress compared with the existing ones. It should be noted that although the technical effects of the foregoing technical features are described in sections, each part is not separated, but a coordinated overall technical solution.
