Description

Technical Field

[0001] The present invention relates to the field of cleaning equipment design, and more particularly to a floor brush and a cleaning device. Background Art

[0002] When cleaning floors, carpets, etc. in the home, cleaning equipment such as a floor washer is often used. The above cleaning equipment includes a floor brush, and the floor brush usually includes a rotating brush and comb teeth. The rotating brush can rotate on the surface of the floor or carpet to scrub the surface of the above structure, removing dirt, oil stains and other stubborn stains to achieve the cleaning effect.

[0003] During the cleaning process of the rotating brush, it will inevitably stick to the garbage remaining on the floor or carpet. The comb teeth can be used to contact the garbage stuck on the rotating brush and scrape off the above garbage as the rotating brush rotates relative to it to prevent the garbage from hindering the work of the rotating brush.

[0004] When using the above cleaning equipment, it is found that since floors or carpets often have hair attached, the hair is easily wound around the rotating brush during the cleaning of the rotating brush. However, the conventional comb teeth are difficult to effectively scrape off the hair wound around the rotating brush, and the accumulation of hair over time will affect the cleaning use of the rotating brush and even damage the rotating brush seriously. Summary of the Invention

[0005] The purpose of the present invention is to provide a comb tooth that can solve one or more of the above problems.

[0006] According to one aspect of the present invention, there is provided a floor brush including a rotating brush and comb teeth.

[0007] The comb teeth are arranged on the axial side of the rotating brush, and the comb teeth can reciprocate relative to the rotating brush.

[0008] The beneficial effect of this floor brush is that in this floor brush, by arranging the comb teeth on the axial side of the rotating brush and enabling the comb teeth to reciprocate relative to the rotating brush, the comb teeth can effectively scrape off the garbage on the rotating brush. At the same time, when there is hair wound around the rotating brush, during the reciprocating movement of the comb teeth, the comb teeth can move radially towards the rotating brush. When the comb teeth are close to the rotating brush, the comb teeth can better contact the hair on the rotating brush and form extrusion and cutting on the hair, or the comb teeth can move along the axis of the rotating brush, and the comb teeth can apply a shearing force to the hair on the rotating brush to effectively remove the hair from the rotating brush, better ensuring the cleaning use of the rotating brush.

[0009] In some embodiments, the comb teeth can reciprocate along the axial or radial direction of the rotating brush.

[0010] In some embodiments, the comb teeth include a main body and a comb tooth part, and the comb tooth part is connected to the main body.

[0011] The included angle formed by the comb teeth part and the bottom surface of the main body is 45° to 135°.

[0012] The comb teeth part is provided with a plurality of teeth, and grooves are provided between adjacent teeth, and a cutting part is arranged in the grooves. The teeth of this comb can be used to scrape off the garbage attached to the roller brush on the cleaning device, and the cutting part is arranged on the teeth, and the cutting part can facilitate the cutting of the hair entangled on the roller brush, so as to eliminate the retention of the hair on the roller brush and ensure the effective operation of the roller brush.

[0013] In some embodiments, both sides of the cutting part are respectively connected to two adjacent teeth.

[0014] In some embodiments, the cutting part is provided with two inclined surfaces, and the ends of the two inclined surfaces meet to form a sharp end.

[0015] In some embodiments, the cutting part includes a first cutting part, a second cutting part and a third cutting part. One side of the second cutting part is connected to the first cutting part, and the other side is connected to the third cutting part. The first cutting part and the third cutting part are respectively connected to two adjacent teeth, and the second cutting part is connected to the bottom of the groove.

[0016] In some embodiments, both the first cutting part and the third cutting part are inclined with respect to the second cutting part, and both the first cutting part and the third cutting part are inclined away from the center of the groove. Thus, the setting of the groove can be increased, so that the hair can enter the groove better and be cut off.

[0017] In some embodiments, the first cutting part is provided with two first inclined surfaces, and the ends of the two first inclined surfaces meet to form a first sharp end. The second cutting part is provided with two second inclined surfaces, and the ends of the two second inclined surfaces meet to form a second sharp end. The third cutting part is provided with two third inclined surfaces, and the ends of the two third inclined surfaces meet to form a third sharp end. The first sharp end, the second sharp end and the third sharp end are on the same plane. Then when the comb teeth make a reciprocating movement, the first sharp end and the third sharp end can move correspondingly to better form a cutting action.

[0018] In some embodiments, the floor brush further includes a driving mechanism, and the driving mechanism controls the comb teeth to make a reciprocating motion. The reciprocating motion frequency of the comb teeth is linked to the rotation speed of the roller brush, and the linkage includes that the reciprocating motion frequency of the comb teeth and the rotation speed of the roller brush are in a preset proportional relationship. By linking the reciprocating motion frequency of the comb teeth and the rotation speed of the roller brush, resonance between the comb teeth and the roller brush can be avoided, thereby avoiding affecting the operation of the comb teeth and improving the cleaning effect of the comb teeth.

[0019] In some embodiments, the floor brush further includes a hair detection sensor configured to detect the roller brush. When the hair detection sensor is triggered, the drive mechanism controls the comb teeth to increase the reciprocating motion frequency. The setting of the hair sensor facilitates increasing the working intensity of the comb teeth in a timely manner when a large amount of hair is wound around the roller brush, so as to ensure that the comb teeth can effectively remove the hair.

[0020] In some embodiments, the local floor brush further includes a torque sensor configured to detect the torque of the roller brush. When the torque sensor detects that the torque value of the roller brush exceeds the preset range of the reference value, the drive mechanism controls the reciprocating frequency of the comb teeth to be adjusted according to the formula f = K×(T - T0),

[0021] where f is the adjusted frequency (times / minute), K is the proportionality coefficient, T is the real-time torque value, and T0 is the reference torque value. By detecting the torque of the roller brush to adjust the reciprocating frequency of the comb teeth, the cleaning ability of the comb teeth can be improved, and the hair, dirt, etc. on the roller brush can be better removed.

[0022] According to one aspect of the present invention, a cleaning device is provided, including a body and a floor brush, and the floor brush is installed on the body. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Refer to Figure 4 、 Figure 5 and Figure 6 A kind of comb tooth in this embodiment includes a main body 1 and a comb tooth part 2, wherein the comb tooth part 2 is integrally formed and connected to the main body 1.

[0040] The comb tooth part 2 can be vertically arranged with respect to the bottom surface of the main body 1 or be inclined with respect to the bottom surface of the main body 1. The included angle between the comb tooth part 2 and the bottom surface of the main body 1 is 45° - 135°. In this embodiment, the included angle a between the comb tooth part 2 and the bottom surface of the main body 1 is preferably 90°.

[0041] A plurality of teeth 21 are arranged on the comb tooth part 2, and grooves 22 are arranged between adjacent teeth 21. Cutting parts are respectively arranged in the grooves 22 between each adjacent pair of teeth 21.

[0042] The cutting part 23 includes a first cutting part 231, a second cutting part 232 and a third cutting part 233. One side of the second cutting part 232 is integrally connected to the first cutting part 231, and the other side of the second cutting part 232 and the third cutting part 233 are integrally connected.

[0045] Embodiment 3

[0046] Reference Figure 7 , A floor brush in this embodiment includes a rotary brush 20 and comb teeth 30. The comb teeth 30 can be the comb teeth described in Embodiment 1 or the comb teeth described in Embodiment 2.

[0047] The rotary brush 20 can perform a rotational motion, and the comb teeth 30 are arranged on the axial side of the rotary brush 20, and the comb teeth 30 can perform a reciprocating motion relative to the rotary brush 20. Among them, the motion of the comb teeth 30 can be a radial motion along the rotary brush 20, or an axial motion along the rotary brush 20, or an irregular motion along a combination of the radial and axial directions of the rotary brush 20, etc.

[0048] During the motion of the comb teeth 30, when the comb teeth 30 move radially along the rotary brush 20, when the comb teeth 30 approach the rotary brush 20, the comb teeth 30 can better contact the hair on the rotary brush 20 and form a squeezing cut on the hair, or when the comb teeth 30 move axially along the rotary brush 20, the comb teeth 30 can apply a shearing force to the hair on the rotary brush 20 to effectively remove the hair from the rotary brush.

[0049] The floor brush in this embodiment can further include a driving mechanism, and the driving mechanism can include any one of the following structures: (1) a cam mechanism driven by a motor; (2) a crank and connecting rod mechanism; (3) a gear and rack transmission mechanism.

[0050] The drive mechanism is connected to the comb teeth 30 so that the reciprocating motion of the comb teeth 30 can be controlled by the drive mechanism, and the reciprocating motion frequency of the comb teeth 30 is linked with the rotation speed of the roller brush 20 to avoid resonance between the movement frequencies of the two, such as limiting the ratio of the comb teeth movement to the roller brush rotation number (such as 1:5~1:15) to avoid resonance between the movement frequencies of the two, such as when the roller brush rotation speed is 10r / s, the comb teeth complete a reciprocating stroke every 0.5~1.5s. Preferably, the drive mechanism controls the comb teeth 30 to move at a reciprocating frequency of 5-60 times / minute, and the comb teeth 30 complete a complete reciprocating stroke when the roller brush 20 rotates 5-15 times (circles).

[0051] And specifically, the movement of the comb teeth 30 can be divided into low frequency and high frequency, which can be switched by the control of the driving mechanism.

[0052] When the comb teeth 30 are at a low frequency, the comb teeth 30 will be at a reciprocating frequency of 5-30 times / minute, which is suitable for daily cleaning, while ensuring the hair removal effect and reducing energy consumption and noise; when the comb teeth 30 are at a high frequency, the comb teeth 30 will be at a reciprocating frequency of 30-60 times / minute, which is aimed at the hair seriously entangled on the roller brush 20, and can enhance the cleaning power through high-frequency combing. For example, when the frequency is less than 5 times / minute, the cleaning efficiency of a single stroke is <40%; when the frequency is 10 times / minute, the cleaning efficiency reaches 78% and the noise is <65dB; when the frequency is greater than 60 times / minute, the energy consumption increases by 120% and the efficiency is only improved by 15%.

[0053] Under normal conditions, the driving mechanism controls the comb teeth 30 to be at a reciprocating frequency of 10-30 times / minute, which, after a large number of experiments, is the best range for balancing cleaning efficiency and mechanical wear.

[0054] The floor brush of this embodiment may also include a hair detection sensor, which is configured to detect the roller brush 20 to detect the amount of hair wrapped around the roller brush 20. When the amount of hair reaches a certain value, the hair detection sensor can be triggered. At this time, the driving mechanism will control the comb teeth to increase the reciprocating motion frequency, for example, changing the comb teeth 30 at a low frequency to a high frequency.

[0055] In addition, the high frequency duration of the comb teeth 30 can be further limited, such as the comb teeth 30 can return to a low frequency after maintaining high frequency operation for 10-30 seconds.

[0056] The floor brush of this embodiment can further include a torque sensor. When it is detected that the torque value of the roller brush exceeds the preset range of the reference value (such as 20% - 50%), the reciprocating frequency of the comb teeth is controlled to be adjusted according to the formula f = K×(T - T0), where f is the adjusted frequency (times / minute), K is the proportionality coefficient, preferably 0.2 - 2.0, T is the real-time torque value, and T0 is the reference torque value. By detecting the torque of the roller brush to adjust the reciprocating frequency of the comb teeth, the cleaning ability of the comb teeth can be improved, and the hair, dirt, etc. on the roller brush can be better removed.

[0057] Embodiment 4

[0058] Reference Figure 7 and Figure 8 A cleaning device of this embodiment includes a body 10 and a floor brush. The floor brush can preferably be the floor brush described in Embodiment 3.

[0059] The floor brush is installed on the body 10, and a motor is provided in the body 10. The motor can drive the roller brush 20 on the floor brush to rotate.

[0060] When this cleaning device is in use, the roller brush 20 can contact the floor, carpet and other surfaces to be cleaned, and the roller brush 20 can rotate to clean the above-mentioned surfaces to be cleaned. The comb teeth part 2 of the comb teeth 30 can scrape the garbage adhered to the roller brush 20, and the hair wound on the roller brush 20 can be cut by the cutting part 23 and then scraped by the comb teeth part 20, so as to effectively reduce the influence of garbage and hair on the work of the roller brush 20. In addition, the comb teeth 30 can move reciprocally relative to the roller brush 20 to increase the force applied by the cutting part 23 to the hair wound on the roller brush 20, so as to cut the hair more effectively, thereby effectively reducing the influence of garbage and hair on the work of the roller brush 20.

[0061] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
