The present invention has the following effects.
According to the vacuum cleaner brush head and the dust collecting method of the present invention, the front wiping plate and the back wiping plate reciprocate in opposite directions in the cleaning process. Compared with the columnar brush in the conventional vacuum cleaner, the wiping plate moves back and forth, so that the cleaning area of the wiping plate becomes larger and can extend from the left edge to the right edge of the bottom of the brush head body. Since the cleaning area is larger, the dust absorption and cleaning efficiency is improved. Further, since the front wiping plate and the back wiping plate reciprocate in opposite directions, the cleaning effect by the reciprocating wiping is remarkably improved as compared with the one-way rotary wiping of the columnar brush in the conventional vacuum cleaner. Further, since the floor is not wiped by the rolling wiping method, the problem that the hair is entangled with the columnar brush in the prior art is overcome. Further, in the present invention, since the acting force of the rag and the ground is larger than that of the columnar brush, it becomes easy to clean the dust firmly adhering to the ground.

Further, the front wiping plate is provided with dust passage holes penetrating the upper and lower ends thereof, and the dust suction port always overlaps with the dust passage holes. As a result, when the negative pressure generator is activated, when dust enters the dust collection tank of the front wipe plate, most of the dust is sucked through the dust suction port before touching the rag on the front wipe plate and touches the ground. The remaining dust is removed by a rag on the pre-wiping plate and the post-wiping plate. Further, the rag on the front wiping plate pushes large-sized and heavy dust into the area where the dust suction port is located, and is further sucked from the dust suction port. That is, in the present invention, by pushing the dust to the dust suction port by the front wiping plate, both of them cooperate to achieve an efficient dust suction cleaning action. The present invention has significant technological advances over the prior art, in which combinations such as roller brushes and dust vents, columnar brushes and dust vents operate independently or are inadequately collaborated. The remarkable improvement of the dust collection and cleaning effect by such collaboration cannot be predicted from the prior art.

Further, when the dust suction pipe performs the dust suction work, the air in the dust collection tank is sucked out to form a negative pressure space, and the dust cloth on the wiping plate comes into close contact with the ground due to the action of the atmospheric pressure difference. .. This allows the vacuum cleaner brush head to come into close contact with the ground without the need for the user to press hard. In addition, the frictional force between the rag and the ground becomes remarkably strong, and dust firmly attached to the ground can be removed. This cannot be achieved by conventional technology and has significant progress.

Further, the front wiping plate is provided with dust passage holes penetrating the upper and lower ends thereof, so that the space at the bottom of the brush head body occupied by the dust suction port is significantly reduced. This increases the area ratio of the rag on the wiping plate to the bottom of the brush head body.

Further, a fountain port of the fountain mechanism is provided at the bottom of the brush head main body and is located between the front wiping plate and the back wiping plate. As a result, as the vacuum cleaner brush head progresses, the front wipe plate comes into contact with the dry ground, and the back wipe plate comes into contact with the wet ground, so that the front wipe plate wipes the area to be cleaned dry and dust, etc. Achieves dust cleaning, and the post-wiping plate moistens the area to be cleaned. Compared with the simple dry wiping or wet wiping of the prior art, it is possible to treat a plurality of types of dust, and a higher overall cleaning effect can be achieved. As a result, an all-in-one cleaning action including dust absorption, dry wiping, and wet wiping is achieved, and the dust absorption and cleaning effect is further improved.

Furthermore, by providing the fountain port between the front wiping plate and the back wiping plate, the dust suction port and the fountain port are separated by a rag on the front wiping plate, and the cleaning liquid discharged from the fountain port can enter the dust suction port. It is avoided and the motor of the dust suction system is prevented from being damaged by water ingress. That is, both the improvement of the cleaning effect and the improvement of the safety are realized at the same time by the clever structure.

From the above, according to the present invention, the technical effect of significantly increasing the cleaning area of the vacuum cleaner brush head and improving the cleaning effect is achieved. It has outstanding substantive features and significant advances over prior art. Although the technical effects of each of the above technical features have been described step by step, each part is not divided, but is an overall technical solution that works in cooperation and cooperation.

In order to make it easier to understand the above object, feature, and advantage of the present invention, the following will be described in detail with reference to preferred examples and drawings.

Therefore, this embodiment has remarkable progress as compared with the prior art, and the remarkable improvement of the dust suction cleaning effect by such collaboration cannot be predicted from the prior art.

Further, when the dust suction pipe conducts the dust suction work, the air in the dust collection tank 42 is sucked out to form a negative pressure space, and the dust cloth on the wiping plate comes into close contact with the ground due to the action of the atmospheric pressure difference. do. This allows the vacuum cleaner brush head to come into close contact with the ground without the need for the user to press hard. In addition, the frictional force between the rag and the ground becomes remarkably strong, and dust firmly attached to the ground can be removed. This cannot be achieved by conventional technology and has significant progress.

Further, the front wiping plate 4 is provided with dust passage holes 44 penetrating the upper and lower ends thereof, so that the space at the bottom of the brush head main body 2 occupied by the dust suction port 6 is significantly reduced.

From the above, according to the present embodiment, the technical effect of significantly increasing the cleaning area of the vacuum cleaner brush head 1 and improving the cleaning effect is achieved.

Wipe dry, and the post-wiping plate 5 wet wipes the area to be cleaned. In addition, since the pre-wiping plate 4 is wiped dry, it rubs in a relatively dry state and pushes dust and other dust, so dust with a relatively large size is easily pushed to the dust suction port 6, and dry dust with small particles is on the ground. It soars from and is sucked in from the dust suction port 6. The simple dry wiping of the prior art cannot produce the cleaning effect of the ground, and the cleaning effect is far inferior to that of the present embodiment. In addition, the simple wet wiping of the prior art has inferior dust absorption ability, and after the moisture volatilizes, dust and the like remain on the ground. In the conventional wet wiping method, since the fountain port is located at the most advanced position, the hair on the ground tends to adhere to the ground after being moistened, which makes it difficult to suck and clean the hair, and the cleaning effect is far inferior to that of the present embodiment. ..
