Definitions

  • the present application relates to the field of vacuum cleaners, and in particular, to a vacuum cleaner brush head and a dust collection method.
  • Vacuum cleaner is a cleaning device that uses negative pressure to generate suction to remove dirt, and has been used more and more widely.
  • it is difficult to completely remove the dust on the surface of an object to be cleaned by means of suction alone.
  • a vacuum cleaner brush head with bristles has appeared in the prior art, which uses the bristles to scrape the dust to be sucked into a dust collection port.
  • a type of bristles is generally arranged in a cylindrical shape, resulting in a high failure rate due to proneness to tangling by hair; moreover, the acting force is small, thus it can clean floating dust only but is difficult to clean the garbage firmly adhered to the floor, so the cleaning effect is poor. It is very important that the user needs to press the vacuum cleaner brush head hard towards the floor in the prior art, which leads to a physical burden for the user, so the user experience is poor.
  • the sweeping area for accumulated dust is small, and the cylindrical bristles neither can dispose of garbage of a relatively large size, nor can dispose of objects such as hair stuck to the floor, so it is hard for the user to clean and the use experience is bad. It is more important that, the linkage action between the cylindrical bristles and the dust collection port makes the two difficult to cooperate effectively, so there is still much room for improvement in the dust collection effect.
  • some brush heads in the prior art are provided with water spraying devices, but during use, the water spraying devices are easy to wet the garbage such as hair on the floor, resulting in that the garbage is stuck to the floor surface and very difficult to be sucked up and cleaned. Moreover, moisture is easily sucked into the dust collection system from the dust collection port. Once moisture enters the dust collection system, it is very easy to burn the motor of the dust collection system.
  • WO 9827856A1 discloses a floor washing device as a vacuum cleaner nozzle, which can be connected to or built together with a vacuum cleaner suitable for wet vacuum cleaning.
  • a vacuum cleaner brush head including a brush head body, a front wiping plate, a rear wiping plate, a wiping plate driving device, and a water spraying assembly, where a dust collection pipe is provided in the brush head body; the dust collection pipe has a dust collection port formed on the front side of the bottom of the brush head body; the front wiping plate and the rear wiping plate are provided at the bottom of the brush head body, respectively; cleaning cloth is provided on the front wiping plate and the rear wiping plate, respectively; the wiping plate driving device is provided in the brush head body; a water spraying port of the water spraying assembly is provided on the bottom of the brush head body and located between the front wiping plate and the rear wiping plate;
  • the width of the dust passing hole in the forward or backward direction of the front wiping plate, is greater than the width of the dust collection port by the present threshold, to keep the dust collection port overlapping the dust passing hole when the dust passing hole moves reciprocally along with the front wiping plate; alternatively, in the forward or backward direction of the front wiping plate, the width of the dust passing hole is less than the width of the dust collection port by the present threshold, to keep the dust collection port overlapping the dust passing hole when the dust passing hole moves reciprocally along with the front wiping plate.
  • the top of the front wiping plate is transmittingly connected to the wiping plate driving device;
  • the bottom of the front wiping plate has a dust collection groove and a cleaning cloth mounting portion;
  • the front wall of the dust collection groove is located at the front edge of the bottom of the front wiping plate, and the rear wall of the dust collection groove is connected to the cleaning cloth mounting portion; and the dust passing hole is provided in the dust collection groove.
  • the front wall of the dust collection groove has a plurality of notches arranged at intervals, and each of the notches respectively communicates with the dust collection groove.
  • the dust collection groove extends from the middle to both sides at the bottom front edge of the front wiping plate, and occupies more than half of the length of the bottom front edge of the front wiping plate.
  • the number of the dust collection port is one or multiple, and the number of the dust passing hole is one or multiple; when the number of the dust collection ports is multiple, the dust passing holes correspond one-to-one to the dust collection ports or one of the dust passing holes overlaps a plurality of the dust collection ports.
  • the rear wall of the dust collection groove has a plurality of toothed blades, and the cutting edges of the toothed blades face the dust collection groove.
  • the front wall of the dust collection groove also has a plurality of toothed blades, and the cutting edges of the toothed blades face the dust collection groove.

  • the shaft axis of the first journal, the shaft axis of the second journal, and the rotation axis of the crankshaft rod are coplanar; and the distance between the shaft axis of the first journal and the rotation axis of the crankshaft rod is equal to the distance between the shaft axis of the second journal and the rotation axis of the crankshaft rod.
  • the wiping plate driving device is further configured to keep the crankshaft self-balanced when driving the front wiping plate and the rear wiping plate to move reciprocally in opposite directions.
  • At least one group of guide devices is provided between the front wiping plate and the bottom of the brush head body; and the guide devices include a roller, a roller base, a guide rail bar, and a guide rail base; the roller base is fixed on one of the front wiping plate and the brush head body; the roller is rotatably mounted on the roller base, and is in rolling contact with the other of the front wiping plate and the brush head body; the guide rail base is fixed on one of the front wiping plate and the brush head body, and the guide rail bar is fixed on the other of the front wiping plate and the brush head body; the guide rail base is configured to limit the moving direction of the guide rail bar.

  • the guide rail base includes a first base body and a second base body, and the guide rail bar penetrates a gap between the first base body and the second base body.
  • the water spraying port of the water spraying assembly is provided with a nozzle, and the nozzle is detachably mounted at the bottom of the brush head body.
  • the dust collection pipe includes an internal pipe and a flexible joint; the internal pipe is located in the brush head body and one end of the internal pipe is connected to the dust collection port; the other end of the internal pipe is inserted into the flexible joint; the flexible joint is fixed on the brush head body.
  • the flexible joint includes a first sleeve, a second sleeve, and an outer tube; the first end of the first sleeve is inserted into the brush head body, and the second end of the first sleeve is hingedly connected to the second sleeve; the outer tube is sleeved in the second sleeve; the internal pipe passes through the first sleeve and then is inserted into the outer tube; the outer tube and the second sleeve are locked by a snap lug.
  • a wire plug is fixed between the outer tube and the second sleeve, and the wire plug passes through the second sleeve and the first sleeve.
  • the water spraying assembly includes a water tank; the water tank includes a tank body, a tank cover, and a water separation pad; the tank cover is provided at the top of the tank body; the lower part of the tank body has a water outlet; the water separation pad is provided in the tank body and divides the tank body into an upper cavity and a lower cavity; the lower cavity is configured to store water; the height of the central region of the water separation pad is less than that of the edge region, and the central region of the water separation pad has a water injection port for injecting water into the lower cavity; the tank cover is configured to open or close the water injection port.
  • a dust collection method where the vacuum cleaner brush head according to any one of the foregoing items is used to perform the following operations:
  • the method further includes: detecting whether the brush head body is located on the floor, and shunting down the water spraying assembly when the brush head body leaves the floor.
  • the method further includes: receiving a control instruction sent by a mobile terminal for controlling the vacuum cleaner brush head to work, where the control instruction includes one or more of a water spraying assembly start and shutdown instruction, a wiping plate driving device start and shutdown instruction, a negative pressure generation device start and shutdown instruction, a water spray time interval, or an air suction amount.
  • the present invention at least has the following beneficial effects: According to the vacuum cleaner brush head and the dust collection method provided by the present invention, in the cleaning process, the front wiping plate and the rear wiping plate move reciprocally in opposite directions. Compared with the cylindrical bristles in conventional vacuum cleaners, the forward and backward movement of the wiping plates enables the wiping plates to have a larger cleaning area, and even extend from the left edge to the right edge of the bottom of the brush head body. Because the cleaning area is larger, the dust collection cleaning efficiency can be significantly improved. Moreover, because the front wiping plate and the rear wiping plate move reciprocally in opposite directions, the cleaning effect of reciprocal wiping is significantly improved as compared with the unidirectional rotating wiping performed by the cylindrical bristles in a conventional vacuum cleaner.
  • the cleaning cloth in this solution may have a greater acting force with the floor, thereby facilitating the cleaning of garbage firmly adhered to the floor.
  • the front wiping plate is provided with a dust passing hole penetrating the upper and lower ends thereof, the dust collection port is kept overlapping the dust passing hole.
  • the cleaning cloth on the front wiping plate can push garbage of a relatively large size and weight forward to a region where the dust collection port is located, so that the garbage is sucked in from the dust collection port.
  • the garbage is directionally pushed to the dust collection port by means of the front wiping plate, and the two achieve efficient linkage dust collection cleaning.
  • the present invention has a significant technological progress, and the significantly improved dust collection cleaning effect brought about by this linkage is difficult to predict in the prior art.
  • the air in the dust collection groove is pumped out to form a negative pressure space, and under the action of an air pressure difference, the cleaning cloth on the wiping plates is in close contact with the floor.
  • the vacuum cleaner brush head can be in close contact with the floor without being pressed hard by the user, and on the other hand, the friction between the cleaning cloth and the floor is significantly enhanced. The garbage firmly adhered to the floor can be removed. This cannot be implemented by the prior art, and thus a significant progress is achieved.
  • the front wiping plate is provided with a dust passing hole penetrating the upper and lower ends thereof, which can also significantly reduce the space occupation at the bottom of the brush head body by the dust collection portion, thereby increasing the proportion of the area of the cleaning cloth on the wiping plate at the bottom of the brush head body.
  • the water spraying port of the water spraying assembly is provided at the bottom of the brush head body and located between the front wiping palate and the rear wiping plate. Therefore, in the traveling process of the brush head, the front wiping plate is in contact with the dry floor, and the rear wiping plate is in contact with the wet floor, so that the front wiping plate performs dry wiping on the surface to be cleaned to implement the cleaning of garbage such as floating dust, and the rear wiping plate performs wet wiping on the surface to be cleaned.
  • the brush head can dispose of multiple types of garbage, thereby achieving a better overall cleaning effect.
  • the all-in-one cleaning function of dust collection, dry wiping and wet wiping is implemented, and the effects of dust collection and cleaning are further significantly improved.
  • the dust collection port and the water spraying port are separated by the cleaning cloth on the front wiping plate to avoid the possibility that a cleaning liquid sprayed from the water spraying port enters the dust collection port, thereby preventing the motor of the dust collection system from damage by ingress of water. That is, an ingenious structure is used to improve both the cleaning effect and the safety.
  • the present invention can achieve the technical effects of significantly increasing the cleaning area and improving the cleaning effect of the vacuum cleaner brush head, and has prominent substantive features and a remarkable progress as compared with the existing ones. Moreover, it should be noted that although the technical effects of the foregoing technical features are described in paragraphs, the parts are not separate but a coordinated and matched overall technical solution.
