Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning head for a vacuum cleaner and a vacuum cleaner having the cleaning head. Background Art

[0002] In daily life, dust particles, fluff, fine fibers and other dust adherents are easily stained on the surfaces of clothes, fabrics, knitted sofas, etc. These dust adherents are difficult to clean when adhering to the clothes surface. People often use clothes lint brushes to clean the dust adherents on the clothes surface. A clothes lint brush is a tool suitable for cleaning fluff and dust on the clothes surface. It can effectively remove fluff, dust particles and fine fibers on the clothes without damaging the clothes fibers. Clothes lint brushes usually use electrostatic adsorption to adsorb and remove dust adherents (such as dust particles, fluff, fine fibers, flocs, etc.) on the clothes surface. However, these dust adherents are easily stained on the clothes lint brush. Each time during or after cleaning, it is necessary to clean the dust adherents adsorbed on the clothes lint brush before it can be used continuously. Moreover, it is rather cumbersome to clean the clothes lint brush stained with dust adherents. The clothes lint brush that is not cleaned thoroughly is likely to re-stain the dust adherents attached to it on the surface of the clothes to be cleaned. After long-term use, it is easy to reduce the cleaning effect of the clothes lint brush on the surface of the clothes to be cleaned, and the cleaning effect is not ideal enough. In addition, for some dust adherents with strong adhesion ability, such as fine fluff and adherent particles adhering to the clothes surface, it is very difficult for the clothes lint brush to remove these dust adherents with strong adhesion ability by electrostatic adsorption. Therefore, there is an urgent need for a cleaning head for a vacuum cleaner and a vacuum cleaner having the cleaning head that have better cleaning ability for dust adherents on the clothes surface and are more convenient to clean.

The structural composition and principle of the cleaning head 100 will be specifically described below according to the accompanying drawings of the specification.

[0033] According to Figure 1 、 Figure 4 and Figure 5As shown, the cleaning head 100 includes a housing 10, and a suction chamber 11 is constructed inside the housing 10. A suction nozzle 20 is installed on one side of the housing 10, and the suction nozzle 20 has a suction port 21. In this embodiment, an installation surface is provided on one side of the housing 10, and the suction nozzle 20 is connected to the installation surface on one side of the housing 10 by screws.

[0034] To facilitate the adsorption of fluff, fine fibers, etc. attached to the surface to be cleaned, two electrostatic adsorbing members 30 are installed on the suction nozzle 20, and the two electrostatic adsorbing members 30 are arranged at opposite sides of the suction port 21 of the suction nozzle 20. Specifically, two installation grooves 22 are provided on the surface of the suction nozzle 20, and the two installation grooves 22 are distributed at opposite sides of the suction port 21, and the two electrostatic adsorbing members 30 are installed in the two installation grooves 22. In this embodiment, the two electrostatic adsorbing members 30 are snapped into the two installation grooves 22. In other embodiments, the electrostatic adsorbing members 30 can also be adhered to the installation grooves 22 by glue, or the electrostatic adsorbing members 30 and the suction nozzle 20 can also be connected by one of snap connection, screw connection, magnetic attraction connection, clearance fit, and interference fit. In addition, to facilitate better adsorption of fluff, fine fibers, and other dust attachments on the surface of fabrics such as clothes, the electrostatic adsorbing members 30 are not limited to two, and at least one can also be provided according to actual needs, such as a ring-shaped electrostatic adsorbing member 30 installed on the outer peripheral side of the suction port 21 of the suction nozzle 20; or multiple electrostatic adsorbing members 30 can be provided, and the multiple electrostatic adsorbing members 30 are evenly spaced and arranged on the outer peripheral side of the suction port 21 of the suction nozzle 20, without specific limitation. When the cleaning head 100 moves on the surface to be cleaned and performs a cleaning operation, the electrostatic adsorbing members 30 can use the electrostatic adsorption effect to adsorb dust attachments such as fluff, fine fibers, and adhered particulate matters on the surface of fabrics such as clothes, and suck these dust attachments through the suction port 21 of the suction nozzle 20.

[0035] To facilitate the scraping of dust attachments such as fluff and fine fibers on the surface to be cleaned, a scraping strip 50 is installed on the suction nozzle 20. The scraping strip 50 is rotatably arranged on the suction nozzle 20 around an axis and spans the suction port 21. Specifically, rotating members 56 are installed at both ends of the scraping strip 50, and rotating grooves 23 are arranged on both opposite sides of the suction port 21 of the suction nozzle 20. The rotating members 56 are rotatably fitted in the rotating grooves 23. In this embodiment, the shape of the rotating member 56 is cylindrical, and the rotating fit structure between the scraping strip 50 and the suction nozzle 20 is a rotating fit structure between a cylinder and a groove. In other embodiments, the rotating fit structure between the scraping strip 50 and the suction nozzle 20 can also adopt a shaft-hole fit. For example, rotating shafts extending towards each other are arranged on both opposite inner sides of the suction port 21 of the suction nozzle 20, and rotating holes matching the rotating shafts are arranged at both ends of the scraping strip 50; or rotating holes are arranged on both opposite inner sides of the suction port 21 of the suction nozzle 20, and rotating shafts matching the rotating holes are arranged at both ends of the scraping strip 50; or bearings are installed at both ends of the scraping strip 50, and corresponding shaft seats are installed on both sides of the suction port 21 of the suction nozzle 20 to support the bearings. There is no specific limitation.

[0036] When the cleaning head 100 moves on the surface to be cleaned and performs a cleaning operation, the scraping strip 50 can rotate around an axis and scrape the surface to be cleaned, scraping off dust attachments such as fluff, adhered particulate matters, and fine fibers adhered to the surface of fabrics such as clothes without damaging the surface of fabrics such as clothes.
