Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a roller brush cleaning mechanism and a vacuum cleaner. Background Art

[0002] Vacuum cleaners can be divided into vertical, horizontal and portable types according to their structure. The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, generate negative air pressure in the sealed shell, and absorb dust. Vacuum cleaners are mainly divided into three types: household vacuum cleaners, commercial vacuum cleaners and industrial vacuum cleaners. Among them, horizontal vacuum cleaners are generally rectangular or car-shaped, with two parts, the front part is the dust collection box, and the rear part is the motor part. The fan impeller of the vacuum cleaner is driven by the motor at high speed, and the air in the dust collection part is continuously replenished into the fan. This can form a higher pressure difference with the outside world. The dust and dirt from the suction nozzle are sucked into the dust collection part with the air, and pass through the drain to collect the dust and dirt in the dust cylinder.

[0003] When cleaning, the current horizontal vacuum cleaner mainly uses a roller brush structure to clean the ground, and then sucks the cleaned garbage into the shell. However, the suction force cannot remove easily entangled objects such as hair and some adhesive objects with a certain stickiness, which causes a certain impact on subsequent cleaning.

[0004] To this end, the utility model proposes a roller brush cleaning mechanism and a vacuum cleaner to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a roller brush cleaning mechanism and a vacuum cleaner to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a roller brush cleaning mechanism and a vacuum cleaner, including a roller brush assembly; the roller brush assembly includes a bracket fixed at the side wall of the body opening, a support movably arranged at the branch of the bracket, a bearing seat embedded in the middle position of the support, an axle fixed inside the bearing seat, and a roller brush body connected to the axle, wherein comb teeth are symmetrically arranged obliquely above the roller brush body, and the ends of the comb teeth are fixed to the inner side of the bracket branch.

[0007] Preferably, there is an extrusion and interference state between the circumferential bottom of the roller brush body and the contact surface.

[0008] Preferably, the tooth pitch of the comb teeth is greater than the diameter of the hair roots on the surface of the roller brush body.

[0009] Preferably, a connecting rod is provided on the upper portion of the support, and the end of the connecting rod is limited by a nut and the end of the support and the bracket.

[0010] Preferably, the end of the shaft is drivingly connected to the interior of the machine body.

[0011] Preferably, it includes a vacuum cleaner body, a vacuum cleaner body, a driving wheel movably arranged at the rear of the body, and the above-mentioned roller brush cleaning mechanism arranged at the front of the lower side of the body, the vacuum cleaner body has a built-in information interaction module, and the vacuum cleaner body adopts a wireless cruise setting.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model adds a comb tooth structure to remove the hair entangled on the surface of the roller brush body and the dust adsorbed thereon. The fallen dust will be collected in the dust collection box under the suction effect of the internal body of the machine, while the hair and other filaments will be entangled between the tooth roots of the comb teeth. The machine body is opened regularly to clean the comb teeth, thereby preventing the roller brush body from being affected by excessive entanglement of hair and excessive accumulation of dust and impurities adsorbed on the surface. In addition, the comb teeth have a simple structure, low cost and high practical value.

[0014] Among them, the roller brush body is divided into two positions: working state and self-cleaning state. When the roller brush body is in the working state, the roller brush body is in the lowest position and is responsible for cleaning the contact parts. When the roller brush body is in the self-cleaning state, the roller brush body is in the highest position. At this time, the roller brush body is in full contact with the comb teeth. The position limit of the roller brush body needs to be adjusted through the installation position of the nut and the connecting rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] See also Figure 1-Figure 4 , in the figure: This embodiment is a preferred implementation of the technical solution, a roller brush cleaning mechanism and a vacuum cleaner, including a roller brush assembly 3; the roller brush assembly 3 includes a bracket 32 ​​fixed to the side wall of the opening of the body 1, a support 31 movably arranged at the branch of the bracket 32, a bearing seat 34 embedded in the middle position of the support 31, a shaft 37 fixed inside the bearing seat 34, and a roller brush body 35 connected to the shaft 37, and comb teeth 36 are symmetrically arranged obliquely above the roller brush body 35, and the ends of the comb teeth 36 are fixed to the inner side of the branch of the bracket 32;

[0023] It should be noted that the end of the shaft 37 is connected to the internal driving of the body 1. The vacuum cleaner includes a vacuum cleaner body, a vacuum cleaner body 1, a driving wheel 2 movably arranged at the rear of the body 1, and a roller brush cleaning mechanism arranged at the front of the lower side of the body 1. The vacuum cleaner body has a built-in information interaction module, and the vacuum cleaner body adopts a wireless cruise setting. The vacuum cleaner involved in this application is similar to the principle of a sweeping robot, and adopts intelligent remote control cruise cleaning and vacuuming. It is a relatively conventional device at present, and its implementation principle will not be further described. Moreover, in the present application, a comb tooth 36 structure is added to remove the hair entangled on the surface of the roller brush body 35 and the adsorbed dust. The fallen dust will be collected in the dust collection box under the suction action of the body 1, and the filaments such as hair will be entangled between the roots of the comb teeth 36. The body 1 is opened regularly to clean the comb teeth 36, so as to avoid the roller brush body 35 from being affected by excessive entanglement of hair and accumulation of dust and impurities adsorbed on the surface, thereby affecting subsequent cleaning. In addition, the comb teeth 36 have a simple structure, low cost and high practical value.

[0024] Among them Figure 1 and Figure 2 As shown, the bottom of the peripheral side of the roller brush body 35 and the contact surface are in a state of extrusion and resistance;

[0025] It should be noted that the compression between the roller brush body 35 and the contact surface increases the friction damping between the two, so that the roller brush body 35 cleans the contact surface with greater friction damping during the rotation process.

[0026] Among them Figure 3 and Figure 4 As shown, the tooth pitch of the comb teeth 36 is greater than the diameter of the hair roots on the surface of the roller brush body 35; a connecting rod 33 is provided on the upper part of the support 31, and the end of the connecting rod 33 is limited by a nut and the end of the support 31 and the bracket 32

[0027] It should be noted that when the roller brush body 35 is driven to rotate, the hair roots evenly distributed on its circumference are in continuous contact with the comb teeth 36, thereby cleaning the hair entangled between the hair roots and shaking off the dust. The roller brush body 35 is divided into two positions: a working state and a self-cleaning state. When the roller brush body 35 is in the working state, the roller brush body 35 is in the lowest position and is responsible for cleaning the contact parts. When the roller brush body 35 is in the self-cleaning state, the roller brush body 35 is in the highest position. At this time, the roller brush body 35 is in full contact with the comb teeth 36. The position limit of the roller brush body 35 needs to be adjusted by the nut and the installation position of the connecting rod 33.

[0028] In this embodiment, a comb tooth 36 structure is additionally provided to remove hair entangled on the surface of the roller brush body 35 and dust adsorbed thereon. The fallen dust will be collected in the dust collection box under the suction action inside the machine body 1, while filaments such as hair will be entangled between the tooth roots of the comb teeth 36. The roller brush body 35 is divided into two positions: a working state and a self-cleaning state. When the roller brush body 35 is in the working state, the roller brush body 35 is in the lowest position and is responsible for cleaning the contact parts. When the roller brush body 35 is in the self-cleaning state, the roller brush body 35 is in the highest position. At this time, the roller brush body 35 is in full contact with the comb teeth 36. The position limit of the roller brush body 35 needs to be adjusted by the nut and the installation position of the connecting rod 33. The machine body 1 is opened regularly to clean the comb teeth 36, so as to avoid the roller brush body 35 from being affected by excessive entanglement of hair and accumulation of dust and impurities adsorbed on the surface, thereby affecting subsequent cleaning.
