Description

Technical Field

[0001] The invention belongs to the technical field of cleaning appliances, and in particular relates to a vacuum cleaner floor brush with a rear scraper strip. Background Art

[0002] Vacuum cleaners are common cleaning tools in daily life. During operation, they use a motor to drive the blades to rotate, generating negative pressure in the sealed shell, thereby sucking in foreign objects on the surface to be cleaned. The floor brush cleaning head is an important component of the vacuum cleaner, and its working efficiency directly affects the cleaning efficiency of the vacuum cleaner.

[0003] In the floor brush structure of a vacuum cleaner, a scraping bar is usually provided at the rear of the floor brush. During the cleaning process of the floor brush, the scraping bar can play a cleaning effect when pushed forward, but the scraping bar is usually fixedly connected and cannot be retracted. When the floor brush is pushed backward, the particles are blocked by the scraping bar and cannot be sucked into the vacuum cleaner. The cleaning efficiency of the vacuum cleaner is poor and the floor brush is not easy to move, which affects the user experience. Summary of the invention

[0004] The purpose of the present invention is to provide a vacuum cleaner floor brush with a rear-mounted scraper bar in order to solve the problem that the scraper bar on the floor brush of a vacuum cleaner cannot be retracted, resulting in the floor brush being difficult to move when the floor brush is pushed back, and the particles are blocked by the scraper bar when the floor brush is pulled back and cannot be sucked into the vacuum cleaner, thereby improving the cleaning efficiency of the vacuum cleaner.

[0005] In order to achieve the above object, the present invention provides a vacuum cleaner floor brush with a rear scraper strip, which comprises:

[0006] A floor brush body, wherein a roller brush is arranged inside the floor brush body, and a mounting hole is arranged on the floor brush body, wherein the mounting hole is located behind the roller brush;

[0007] A scraper bar, the scraper bar is rotatably connected to the floor brush body, and the scraper bar is located in the mounting hole;

[0008] The driving assembly comprises a driving component, a connecting rod and a detecting component, wherein the detecting component is used to detect the rotation information of the large wheel, the detecting component is connected to the driving component, one end of the connecting rod is connected to the driving component, and the other end of the connecting rod is connected to the scraper strip.

[0009] As a further description of the above technical solution:

[0010] The detection component is a large wheel forward and backward rotation detector.

[0011] As a further description of the above technical solution:

[0012] The driving component is a push-pull type solenoid valve.

[0013] As a further description of the above technical solution:

[0014] The scraper strip includes a mounting seat, a spring, a connecting plate and a scraper blade. The mounting seat is rotatably connected to the floor brush body, one end of the spring is connected to the mounting seat, the other end of the spring is connected to the connecting plate, and the scraper blade is detachably connected to the connecting plate.

[0015] As a further description of the above technical solution:

[0016] A mounting groove is arranged in the mounting seat, the spring is located in the mounting groove, and the connecting plate is movably connected in the mounting groove.

[0017] As a further description of the above technical solution:

[0018] The scraper blade is detachably connected to the connecting plate.

[0019] As a further description of the above technical solution:

[0020] Blocking components are respectively arranged on both sides of the scraping strip, one side of the blocking component is connected to the scraping strip, and the other side of the blocking component is connected to the floor brush body.

[0021] As a further description of the above technical solution:

[0022] The blocking assembly includes a motor, a first gear, a second gear, a rotating shaft and a blocking cloth. The motor is connected to the floor brush body. The first gear is arranged on the driving shaft of the motor. The first gear is meshed with the second gear. The second gear is connected to the rotating shaft.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. In the present invention, the driving component, connecting rod and detection component are arranged so that the detection component can control the movement of the driving component according to the rotation direction of the large wheel. When the large wheel moves forward, the driving component rotates the scraper bar through the connecting rod, so that the scraper bar contacts the ground to clean the ground, which can ensure that the floor brush has good air tightness with the ground, increase the vacuum degree, and push all missed dust into the suction port. When the large wheel moves backward, the driving component rotates the scraper bar through the connecting rod, so that the scraper bar does not contact the ground, which facilitates the movement of the floor brush; it is also convenient for the vacuum cleaner to clean the ground when it is pushed backward, thereby improving the cleaning efficiency; at the same time, before the vacuum cleaner is pushed forward to finish cleaning, the driving component drives the scraper bar to swing forward and retract through the connecting rod backward, thereby pushing all missed dust into the suction port, and the suction port can take away large particles, thereby improving the cleaning efficiency.

[0025] 2. In the present invention, the scraper strip is composed of a mounting seat, a spring, a connecting plate and a scraper blade. When the scraper blade encounters a stubborn obstacle, the spring is compressed, thereby facilitating the scraper blade to pass through the obstacle, preventing the scraper blade from being damaged, thereby protecting the scraper blade, and ensuring that the scraper blade is always in contact with the ground, thereby improving the cleaning quality.

When the large wheel moves forward, the driving component rotates the scraper bar through the connecting rod, so that the scraper bar contacts the ground to clean the ground, which can ensure that the floor brush has good air tightness with the ground, increase the vacuum degree, and push the missed dust into the suction port. When the large wheel moves backward, the driving component rotates the scraper bar through the connecting rod, so that the scraper bar does not contact the ground, which facilitates the movement of the floor brush. The scraper bar consists of a mounting seat, a spring, a connecting plate and a scraper blade.
