Description

Technical Field

[0001] This utility model belongs to the field of cleaning, specifically, it relates to a cleaning brush. Background Technology

[0002] Small brushes, crevice tools, and squeegees are essential accessories for vacuum cleaners or cleaning machines. These three accessories have different applications: crevice tools are mainly for crevices and corners, small brushes are mainly for surfaces such as furniture, office furniture, and fabrics, and squeegees are mainly used to absorb water from bathroom puddles and carpets. Different applications require different accessories, and replacing and storing them is very inconvenient.

[0003] Patent document CN213820247U discloses a cleaning brush with a quick-release structure. It includes a rod body and a cleaning section. The quick-release structure includes a push shaft, a return spring, a movable chuck sleeve, and a fixed chuck sleeve. The push shaft can move inside the rod body and is fixedly connected to the movable chuck sleeve. The return spring is disposed inside the rod body and sleeved on the push shaft. The fixed chuck sleeve is fixed to the bottom of the rod body. Within the fixed cavity formed by the movable and fixed chuck sleeves, a connecting body is hinged within the movable and fixed chuck sleeves in use. The cleaning section can rotate along the rod axis. By providing a quick-release push rod, the push rod can be operated from the upper part of the cleaning rod without direct contact with the brush head, enabling contactless replacement of the brush head for functions such as brushing, sweeping, mopping, and dust removal. However, this invention still requires changing the type of cleaning section for different application scenarios.

[0004] Furthermore, the existing small brushes, flat nozzles, and squeegees do not adhere well to the cleaning surface, especially on hard surfaces, resulting in low cleaning efficiency of the small brushes or flat nozzles. Squeegees also leave cleaning residue and reduce efficiency when absorbing water. Small brushes or flat nozzles are usually made of hard plastic, which can easily damage the surface of the object being cleaned, especially soft surfaces. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of this utility model is to provide a cleaning brush.

[0006] A cleaning brush according to the present invention includes: a suction port, an air duct, and a mounting part, wherein the suction port is made of an elastic element;

[0007] The suction port includes a first sidewall, a second sidewall, and at least one set of third sidewalls. The first sidewall and the second sidewall are arranged opposite each other, and the at least one set of third sidewalls is used to connect the first sidewall and the second sidewall.

[0008] The first sidewall includes a first main wall and a first extended wall. The length of the first main wall is greater than the length of the second sidewall. The connection between the first main wall and the first extended wall is flexible.

[0009] The connection between the first main wall and the first extended wall, the edge of the second side wall, and the edge of the third side wall are on the same plane, forming the suction port surface.

[0025] Mounting part 3 Third side wall 13 Suction port surface 4 Detailed Implementation

[0026] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0027] like Figures 1-6 As shown, this embodiment provides a cleaning brush, including: a suction port 1, an air duct 2, and a mounting part 3, wherein the suction port 1 is made of an elastic element;

[0028] The suction port 1 includes a first sidewall 11, a second sidewall 12 and at least one set of third sidewalls 13. The first sidewall 11 and the second sidewall 12 are arranged opposite each other, and the at least one set of third sidewalls 13 is used to connect the first sidewall 11 and the second sidewall 12.

[0029] The first sidewall 11 includes a first main wall 111 and a first extended wall 112. The length of the first main wall 111 is greater than the length of the second sidewall 12. The connection between the first main wall 111 and the first extended wall 112 is flexible.

[0030] The connection between the first main wall 111 and the first extended wall 112, the edge of the second side wall 12, and the edge of the third side wall 13 are on the same plane, forming the suction surface 4.

[0031] In one embodiment, the cross-sectional width of the air duct section 2 near the suction port 1 is greater than the cross-sectional width of the air duct section 2 near the mounting portion 3. That is, the air duct section 2 has a gradually changing cross-section, with a narrower cross-section near the suction port 1 and a wider cross-section near the mounting portion 3. This change in cross-sectional area reduces airflow resistance, thereby increasing the suction power of the vacuum cleaner or cleaning machine and preventing clogging by particulate dust.

[0032] Mounting part 3 can be connected to a vacuum cleaner or cleaning machine; the size of the connection port is set according to the connection port of the vacuum cleaner or cleaning machine.

[0033] In one embodiment, the elastomer is a soft rubber.

[0034] In one embodiment, the first main wall 111 and the second side wall 12 are disposed on the short side of the suction port surface 4, and the third side wall 13 is disposed on the long side of the suction port surface 4.

[0035] The cleaning brush provided in this embodiment combines the functions of a small brush, a flat nozzle, and a squeegee. As an accessory for a vacuum cleaner or cleaning machine, it eliminates the need for frequent accessory replacements, making it very convenient. Furthermore, it can efficiently remove accumulated dust, particles, and water residue, enhancing the user experience.

[0036] Specifically, when the cleaning brush is used as a small brush, the connection between the first main wall 111 and the first extended wall 112 of the cleaning brush does not bend or move. The first extended wall 112 of the first side wall 11 is equivalent to the soft bristles of the brush head of a small brush for a vacuum cleaner or cleaning machine accessory, which can clean areas such as the edges and crevices of furniture, offices, and fabrics.

[0037] When the cleaning brush is used as a flat suction device, the connection between the first wall 111 and the first extended wall 112 of the cleaning brush bends and moves. The first extended wall 112 deforms to be on the same plane as the suction surface 4, so that the suction surface 4 is fully exposed. The suction surface 4 is flat or nearly rectangular. The flat or nearly rectangular shape can clean crevices or corners more thoroughly.

[0038] When the cleaning brush is used as a squeegee, the connection between the first wall 111 and the first extended wall 112 of the cleaning brush bends and moves. The first extended wall 112 deforms until it is on the same plane as the suction surface 4, so that the suction surface 4 is fully exposed. Since the material of the suction part 1 is an elastic element, the suction surface 4 is closer to the surface to be cleaned. During the cleaning process, water on the cleaning surface is not easy to overflow from the side, thus producing residue, and the water absorption effect is better.

[0039] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0040] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the substantive content of this utility model. Unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.
