Description

A patting brush

Technical Field

The utility model belongs to the technical field of vacuum cleaner floor brushes, and in particular relates to a beating floor brush.

Background Art

The vacuum cleaner motor rotates at high speed, sucking air from the suction port, creating a certain vacuum in the dust box. The dust enters the dust filter bag in the dust box through the floor brush, pipe, handle, hose, and main suction pipe. The dust is retained in the dust filter bag. The filtered air then passes through a layer of filter to enter the motor. This layer of filter is a protective barrier to prevent the dust bag from breaking and sucking dust into the motor. The air entering the motor flows out through the motor. The vacuum cleaner uses the suction effect to suck away dust and debris, such as threads, paper scraps, hair, etc., from floors, carpets, walls, furniture and other surfaces that are not easy to remove dirt with a broom.

The floor brush is one of many accessories and is also a commonly used suction head for cleaning the floor in household vacuuming. It includes a shell, a suction channel connected to a suction pipe is provided in the shell, and a dust suction port connected to the suction channel is provided at the bottom of the shell for dust collection.

The existing floor brush structure only uses suction to clean the dust or small foreign objects attached to the vacuuming surface. It is difficult to completely suck out the dust that is buried inside carpet-like items and covered by the fluff or hair balls on the surface. In order to achieve a satisfactory cleaning effect on the hairy items, the user has to clean the same position repeatedly, and the bottom of the floor brush must be tightly attached to the vacuuming surface. Sometimes it is necessary to pick up the carpet and pat it before vacuuming. This is neither hygienic nor convenient. If it is a large area of carpet or a carpet fixed to the ground, it cannot be achieved. Some vacuum cleaners use a patting device of the floor brush to pat the carpet to pat and suck away the dust, but the floor brush is easily damaged under the high-frequency vibration of the patting device, especially the connector connecting the patting device and the floor brush housing.

Example 1

A flapping floor brush, as shown in Figures 3 to 5, includes a housing 1 and a joint 2 for connecting the housing 1 and a vacuum cleaner (not shown in the figure), the housing 1 has a vacuum cavity connected to the suction pipe of the vacuum cleaner, and the bottom of the housing 1 has a vacuum port 11 connected to the vacuum cavity for vacuuming. The design of the joint 2 and the vacuum cleaner refers to the prior art, and this application does not make any specific restrictions.

The beating floor brush further comprises a beating unit arranged at the bottom of the shell 1 and a connecting assembly for connecting the shell 1 and the beating unit.

The beating unit is located at the front side of the suction port 11 , and includes a beating member 3 , an eccentric member 5 and a driving member.

Referring to Fig. 1 and Fig. 2, the flapping member 3 is formed by covering two flapping members (i.e., the front flapping member 31 and the rear flapping member 32) in front and back, and the bottom surfaces of the front flapping member 31 and the rear flapping member 32 are provided with a plurality of flapping portions 36 protruding outwards. Preferably, a plurality of flapping portions 36 are evenly arranged along the length direction of the flapping member, and the design of the flapping portion 36 has no specific restrictions, and it can refer to the prior art. In the present embodiment, the flapping portion 36 includes a body in a spherical crown shape and a plurality of flapping particles arranged on the body. A holding chamber is formed between the front and rear two flapping members, and the eccentric member 5 and the driving member are located in the holding chamber and in the middle position of the holding chamber. The eccentric member 5 is connected to the driving member and moves under the drive of the driving member, thereby driving the flapping part 36 to reciprocate between the initial position and the flapping position. When the flapping part 36 is in the initial position, the eccentric member 5 does not contact the flapping member 3; when the flapping part 36 switches from the initial position to the flapping position, the flapping part 36 has a tendency to move downward and protrude from the housing 1, so that the ground or carpet can be flapped to raise dust; when the flapping part 36 is in the flapping position, the eccentric member 5 contacts the bottom inner wall of the flapping member 3. Preferably, the driving member is a motor 4, and the eccentric member 5 is arranged on the shaft of the motor 4. There is no specific limitation on the design of the eccentric member 5, and it can also refer to the prior art. In the present embodiment, the eccentric member 5 is semicircular.

The connecting assembly includes a first connecting member 6 and a second connecting member 7 .

The two ends of the first connecting member 6 (i.e., the upper end 61 of the first connecting member and the lower end 63 of the first connecting member) are respectively connected to the housing 1 and the upper end of the flapping member 3, and a first connecting member buffer portion 62 is provided between the two ends of the first connecting member 6. The first connecting member buffer portion 62 has elastic deformation capability, and when the flapping member 3 vibrates, the first connecting member buffer portion 62 plays a vibration reduction and buffering role. Preferably, the first connecting member buffer portion 62 is soft rubber, has a cavity, and is lantern-shaped.

The lower end portion 63 of the first connecting member has a lower groove (i.e., the lower groove 65 of the first connecting member) that matches with the flapping member 3 to engage the flapping member 3, and the upper end portion has an upper groove (i.e., the upper groove 64 of the first connecting member) that matches with the housing 1 to engage the housing 1. Correspondingly, an upper opening 34 is provided on the upper end surface of the flapping member 3, and the connection between the first connecting member 6 and the flapping member 3 can be achieved by clamping the side wall of the upper opening 34 in the lower groove 65 of the first connecting member. A clamping portion that matches with the upper groove 64 of the first connecting member is provided on the housing 1. The two ends of the first connecting member 6 are integrally formed with the first connecting member buffer portion 62, and the two ends of the first connecting member 6 are made of the same material as the first connecting member buffer portion 62. Such a design facilitates the disassembly of the first connecting member 6.

In order to further enhance the connection effect between the upper end of the flapping member 3 and the housing 1, the first connecting member 6 has two symmetrically arranged on the left and right sides of the flapping member 3. Preferably, the upper end of the flapping member 3 has two inwardly recessed areas 33, each of which is provided with a first connecting member 6, and the upper opening 34 is provided in the recessed area 33.

The second connecting member 7 has two parts arranged on the left and right sides of the flapping member 3, and the second connecting member 7 located on the right side of the flapping member 3 is taken as an example for specific description.

The second connecting member buffer part 72 has elastic deformation ability. When the flapping member 3 vibrates, the second connecting member buffer part 72 plays a vibration reduction and buffering role. Similar to the first connecting member buffer part 62, the second connecting member buffer part 72 is soft rubber and has a cavity and is lantern-shaped.

The outer end portion 71 of the second connecting member has an outer groove (i.e., the outer groove 75 of the second connecting member) that matches with the housing 1 to engage with the housing 1, and the inner end portion has an inner groove (i.e., the inner groove 74 of the second connecting member) that matches with the flapping member 3 to engage with the flapping member 3. Accordingly, the side portion of the flapping member 3 has a side opening 35, and the connection between the second connecting member 7 and the flapping member 3 can be achieved by clamping the side wall of the side opening 35 in the inner groove 74 of the second connecting member. A clamping portion that matches the outer groove 75 of the second connecting member is provided on the housing 1.
