Description

Technical Field

[0001] The invention relates to the field of cleaning equipment design, in particular to a floor brush and a cleaning equipment. Background Art

[0002] To clean the floor or carpet in the home, cleaning equipment such as a floor scrubber is often used. The above cleaning equipment includes a floor brush, and the floor brush often includes a roller brush and comb teeth. The roller brush can rotate on the surface of the floor or carpet to scrub the surface of the above structure to remove dirt, oil stains and other stubborn stains, so as to achieve a cleaning effect.

[0003] During the cleaning process, the roller brush will inevitably get stuck with garbage left on the floor or carpet. The comb teeth can be used to contact the garbage stuck on the roller brush and scrape off the garbage as the roller brush rotates relative to it to avoid the garbage hindering the work of the roller brush.

[0004] When using the above-mentioned cleaning device, it is found that since hair is often attached to the floor or carpet, the hair is easily entangled on the roller brush during cleaning. However, conventional comb teeth are difficult to effectively scrape off the hair entangled on the roller brush. After a long period of accumulation, the hair will affect the cleaning use of the roller brush, and in severe cases, it will even damage the roller brush. Summary of the invention

[0005] The object 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, comprising a roller brush and comb teeth. The comb teeth are arranged on the axial side of the roller brush, and the comb teeth can reciprocate relative to the roller brush.

[0007] The beneficial effect of the local brush is: in the local brush, by arranging the comb teeth on the axial side of the roller brush and allowing the comb teeth to reciprocate relative to the roller brush, the comb teeth can effectively scrape off the garbage on the roller brush, and when hair is entangled on the roller brush, the comb teeth can move radially toward the roller brush during the reciprocating motion of the comb teeth. When the comb teeth are close to the roller brush, the comb teeth can better contact the hair on the roller brush and squeeze and cut the hair, or the comb teeth can move along the axial direction of the roller brush, and the comb teeth can apply shear force to the hair on the roller brush to effectively remove the hair from the roller brush, thereby better ensuring the clean use of the roller brush.

[0008] In some embodiments, the comb teeth may reciprocate along the axial direction or radial direction of the roller brush.

[0009] In some embodiments, the comb tooth comprises a main body and a comb tooth portion, wherein the comb tooth portion is connected to the main body. The angle between the comb teeth and the bottom surface of the main body is 45° to 135°. The comb tooth part is provided with a plurality of teeth, and a groove is provided between adjacent teeth, and a cutting part is provided in the groove. The teeth of the comb tooth can be used to scrape off the garbage attached to the roller brush on the cleaning device, and the cutting part is provided on the teeth, and the cutting part can facilitate cutting of the hair entangled on the roller brush to eliminate the hair remaining on the roller brush and ensure the effective operation of the roller brush.

[0010] In some embodiments, two sides of the cutting portion are connected to two adjacent teeth respectively.

[0011] In some embodiments, the cutting portion is provided with two inclined surfaces, and the ends of the two inclined surfaces meet to form a sharp end.

[0012] In some embodiments, the cutting portion includes a first cutting portion, a second cutting portion and a third cutting portion, one side of the second cutting portion is connected to the first cutting portion, and the other side is connected to the third cutting portion, the first cutting portion and the third cutting portion are respectively connected to two adjacent teeth, and the second cutting portion is connected to the bottom of the groove.

[0013] In some embodiments, the first cutting portion and the third cutting portion are both inclined relative to the second cutting portion, and the first cutting portion and the third cutting portion are both inclined away from the center of the groove, thereby increasing the size of the groove so that the hair can better enter the groove and be cut off.

[0014] In some embodiments, the first cutting portion is provided with two first inclined surfaces, the ends of the two first inclined surfaces meet to form a first sharp end, the second cutting portion is provided with two second inclined surfaces, the ends of the two second inclined surfaces meet to form a second sharp end, the third cutting portion is provided with two third inclined surfaces, the ends of the two third inclined surfaces meet to form a third sharp end, and the first sharp end, the second sharp end and the third sharp end are on the same plane. Then, when the comb teeth reciprocate, the first sharp end and the third sharp end can move accordingly to better form a cutting action.

[0015] In some embodiments, the floor brush further comprises a driving mechanism, the driving mechanism controls the comb teeth to reciprocate, the reciprocating frequency of the comb teeth is linked to the rotation speed of the roller brush, and the linkage includes the reciprocating frequency of the comb teeth and the rotation speed of the roller brush being in a preset ratio. By linking the reciprocating frequency of the comb teeth with the rotation speed of the roller brush, resonance between the comb teeth and the roller brush can be avoided, thereby avoiding affecting the work of the comb teeth and improving the cleaning effect of the comb teeth.

[0016] In some embodiments, the floor brush further includes a hair detection sensor, which is 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 provision of the hair sensor can facilitate timely increase of the working intensity of the comb teeth when a large amount of hair is entangled on the roller brush, so as to ensure that the comb teeth can effectively remove the hair.

[0017] In some embodiments, the local brush further includes a torque sensor, which is configured to detect the torque of the roller brush. When the torque sensor detects that the torque value of the roller brush exceeds a preset range of a reference value, the driving mechanism controls the reciprocating frequency of the comb teeth to be adjusted according to the formula f=K×(T-T0). Among them, f is the adjusted frequency (times / minute), K is the proportional coefficient, T is the real-time torque value, and T0 is the reference torque value. By detecting the roller brush torque 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.

[0034] The comb tooth portion 2 and the bottom surface of the main body 1 can be arranged vertically or inclined to the bottom surface of the main body 1, wherein the angle formed by the comb tooth portion 2 and the bottom surface of the main body 1 is 45°~135°. In this embodiment, the angle a formed by the comb tooth portion 2 and the bottom surface of the main body 1 is preferably 90°.

[0035] The comb tooth portion 2 is provided with a plurality of teeth 21 , and grooves 22 are provided between adjacent teeth 21 . A cutting portion is provided in each groove 22 between adjacent teeth 21 .

[0036] The cutting portion 23 includes a first cutting portion 231, a second cutting portion 232 and a third cutting portion 233. One side of the second cutting portion 232 is integrally connected to the first cutting portion 231, and the other side of the second cutting portion 232 is integrally connected to the third cutting portion 233. The first cutting portion 231 and the third cutting portion 233 are respectively integrally connected to two adjacent teeth.

[0037] After setting, the first cutting portion 231 and the third cutting portion 233 are both inclined to the second cutting portion 232 , the second cutting portion 232 is integrally connected to the bottom of the groove 22 , and the first cutting portion 231 and the third cutting portion 233 are both inclined away from the center of the groove 22 .

[0038] In each cutting portion, the first cutting portion 231 is respectively provided with a first inclined surface 2311 on the front and rear sides, and the ends of the two first inclined surfaces 2311 merge to form a first sharp end 2312; the second cutting portion 232 is respectively provided with a second inclined surface 2321 on the front and rear sides, and the ends of the two second inclined surfaces 2321 merge to form a second sharp end 2322; the third cutting portion 233 is respectively provided with two third inclined surfaces 2331 on the front and rear sides, and the ends of the two third inclined surfaces 2331 merge to form a third sharp end 2332; the first sharp end 2312, the second sharp end 2322 and the third sharp end 2332 are on the same plane.

[0039] Example 3 refer to Figure 7 A floor brush of this embodiment includes a roller brush 20 and comb teeth 30. The comb teeth 30 can be the comb teeth described in Example 1 or the comb teeth described in Example 2.

[0040] The roller brush 20 can rotate, and the comb teeth 30 are arranged on the axial side of the roller brush 20, and the comb teeth 30 can reciprocate relative to the roller brush 20, wherein the movement of the comb teeth 30 can be radial movement of the roller brush 20, or axial movement of the roller brush 20, or irregular movement along the combination of radial and axial directions of the roller brush 20, etc.

[0041] During the movement of the comb teeth 30, when the comb teeth 30 moves radially along the roller brush 20, when the comb teeth 30 approaches the roller brush 20, the comb teeth 30 can better contact the hair on the roller brush 20 and squeeze and cut the hair, or when the comb teeth 30 moves axially along the roller brush 20, the comb teeth 30 can apply a shear force to the hair on the roller brush 20 to effectively remove the hair from the roller brush.

[0042] The floor brush of this embodiment may also include a driving mechanism, which may include any of the following structures: (1) a cam mechanism driven by a motor; (2) a crank-connecting rod mechanism; (3) a rack and pinion transmission mechanism.

[0043] 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).

[0044] 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.

[0045] 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%.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] The floor brush of this embodiment can also 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 according to the formula f=K×(T-T0), where f is the adjusted frequency (times / minute), K is the proportional coefficient, preferably 0.2~2.0, T is the real-time torque value, and T0 is the reference torque value. By detecting the roller brush torque 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.

[0050] Example 4 refer to Figure 7 and Figure 8 A cleaning device of this embodiment includes a body 10 and a floor brush, and the floor brush can preferably be the floor brush described in Example 3.

[0051] The floor brush is mounted on the machine body 10, and a motor is disposed in the machine body 10, and the motor can drive the roller brush 20 on the floor brush to rotate.

[0052] When the present cleaning device is in use, the roller brush 20 can contact the ground, carpet or other cleaning surfaces, and the roller brush 20 can rotate to clean the above-mentioned cleaning surfaces, and the comb tooth portion 2 of the comb tooth 30 can scrape off the garbage stuck on the roller brush 20, and the hair entangled on the roller brush 20 can be cut by the cutting portion 23 and then scraped off by the comb tooth portion 20, thereby effectively reducing the influence of garbage and hair on the operation of the roller brush 20. In addition, the comb tooth 30 can reciprocate relative to the roller brush 20 to increase the force of the cutting portion 23 on the hair entangled on the roller brush 20, so as to more effectively cut the hair, thereby effectively reducing the influence of garbage and hair on the operation of the roller brush 20.

[0053] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
