Description

TECHNICAL FIELD

[0001] The present application relates to the field of cleaning equipment, in particular to a floor brush and a cleaning equipment applying the same. BACKGROUND

[0002] The cleaning equipment can clean the ground, and the cleaning task can include wet cleaning of the ground. For example, the scrubber includes a wet rolling brush, which uses the wet rolling brush to clean the ground stains, thereby realizing the wet cleaning function of the ground.

[0003] However, the existing cleaning equipment usually has a problem that although the ground stains are cleaned, water stains are left on the smooth ground. SUMMARY

[0004] The purpose of the present application is to provide a floor brush and a cleaning equipment applying the same to solve the problem that the existing cleaning equipment is easy to leave water stains.

[0005] The floor brush includes a seat body, a mounting seat and a scraping strip, the mounting seat is arranged on the seat body, and the scraping strip is arranged on the mounting seat.

[0006] The mounting seat is provided with a first mounting part, the seat body is provided with a second mounting part, and the first mounting part and the second mounting part are matched with each other to realize the rotatable connection between the mounting seat and the seat body.

[0007] When the mounting seat rotates on the seat body, the scraping strip forms an angle with the surface to be cleaned, and the angle range of the angle between the scraping strip and the surface to be cleaned is 5-180 degrees.

[0008] When the mounting seat is located at the first position, the lower end of the scraping strip is in contact with the surface to be cleaned.

[0009] When the mounting seat is located at the second position, the lower end of the scraping strip is separated from the surface to be cleaned.

[0010] The beneficial effects are that the mounting seat can rotate, so that the scraping strip can also rotate, and the scraping strip and the surface to be cleaned can form an angle in the process of rotation. The scraping strip is suspended on the mounting seat, and the angle is calculated by the angle becoming smaller and smaller when the scraping strip rotates to the outside of the floor brush and becoming larger and larger when the scraping strip rotates to the inside of the floor brush.

[0011] Therefore, when the angle between the scraping strip and the surface to be cleaned is the smallest, the scraping strip rotates to the maximum position to the outside of the floor brush, so that the lower end of the scraping strip is in contact with the surface to be cleaned, and the water stains on the surface to be cleaned are scraped clean.

[0012] When the angle between the scraping strip and the surface to be cleaned is the largest, it means that the scraping strip is rotated to the maximum position towards the inside of the floor brush, so that the lower end of the scraping strip is separated from the surface to be cleaned, and the scraping strip can no longer be in contact with the surface to be cleaned to avoid the water stains on the surface to be cleaned. Thus, the scraping strip cannot be in contact with the surface to be cleaned all the time, and cannot effectively remove the water stains when the water stains are repeatedly scraped.

[0013] In the patent, the lower end of the scraping strip can be switched between the two positions of being in contact with and separated from the surface to be cleaned, that is, the scraping strip is not in contact with the surface to be cleaned all the time.

[0014] In some embodiments, the angle between the scraping strip and the surface to be cleaned is between 80 degrees and 150 degrees.

[0015] In some embodiments, the lower end of the scraping strip is a soft part, and when the mounting seat is in the first position, the scraping strip is in contact with the surface to be cleaned and is deformed in an arc shape. The included angle is the included angle between the tangent at the contact point of the scraping strip and the surface to be cleaned and the surface to be cleaned. The included angle is preferably between 5 degrees and 100 degrees.

[0016] The beneficial effect is that because the lower end of the scraping strip is a soft part, when the scraping strip is in contact with the surface to be cleaned, it can produce a similar interference fit, that is, the scraping strip is in contact with the surface to be cleaned and is deformed in an arc shape, so that there is a tangent at the contact point of the scraping strip and the surface to be cleaned. The included angle between the tangent and the surface to be cleaned is preferably between 5 degrees and 100 degrees, so that the scraping strip can form a good tight contact with the surface to be cleaned to achieve a good water stain scraping effect.

[0017] In some embodiments, when the mounting seat is in the second position, the included angle is the included angle between the extension line of the end of the scraping strip and the surface to be cleaned, and the included angle is between 95 degrees and 180 degrees, preferably between 115 degrees and 170 degrees.

[0018] The beneficial effect is that the scraping strip is continuously rotated and retracted into the floor brush, and when the mounting seat is in the second position, that is, the lower end of the scraping strip is separated from the surface to be cleaned, at this time, the included angle is the included angle between the extension line of the end of the scraping strip and the surface to be cleaned, and the included angle is between 95 degrees and 180 degrees, preferably between 115 degrees and 170 degrees. This included angle cannot be too close to 90 degrees, for example, it is appropriate to be 150 degrees. In this case, if the surface to be cleaned has some large particles, if the included angle is too close to 90 degrees, the scraping strip will be equivalent to a bulldozer, which will continuously roll the large particles forward, and cannot be truly sucked into the inside of the floor brush. However, if the included angle is about 150 degrees, the large particles, the surface to be cleaned, and the scraping strip can form a close friction relationship, so that under the action of friction, it is easier to enter the inside of the floor brush, and thus it is easier to be cleaned.

[0019] In some embodiments, the first mounting part is a rotating shaft, the second mounting part is a mounting hole, the rotating shaft is inserted into the mounting hole, the rotating shaft is rotatable arranged in the mounting hole, a lubricant is arranged between the rotating shaft and the mounting hole, or the rotating shaft and the mounting hole are made of self-lubricating material or a bearing is arranged between the rotating shaft and the mounting hole.

[0020] The beneficial effect is that through the cooperation of the rotating shaft and the mounting hole, the rotating shaft is a circular shaft, the mounting hole is a circular through hole or a counterbore, and the rotating shaft rotates in the mounting hole to realize the rotation of the mounting seat and the scraping strip. In order to ensure better rotation effect, after setting the lubricant, the rotating shaft rotates in the mounting hole, which can reduce noise and resistance. Or the first mounting part is a rotating shaft, and the second mounting part can also adopt a bearing, the end of the rotating shaft is rotatably connected with the bearing, and the rotating shaft can rotate more smoothly at the bearing, thereby reducing noise and resistance.

[0021] In some embodiments, the first mounting part is a rotating shaft, and the second mounting part is a track groove, and the rotating shaft can rotate and slide in the track groove.

[0022] The beneficial effect is that after setting the track groove, the rotating shaft can rotate and slide in the track groove, thereby realizing the angle change of the scraping strip relative to the surface to be cleaned. The scraping strip is switched between contacting and separating from the surface to be cleaned, thereby effectively removing water stains.

[0023] In some embodiments, at least one end of the mounting seat is provided with a switching piece, and the switching piece can be used to drive the entire mounting seat to switch between the first position and the second position.

[0024] The beneficial effect is that through the switching piece, the mounting seat can be conveniently switched between the first position and the second position, thereby realizing the contact or separation of the scraping strip with the surface to be cleaned, thereby realizing the scraping of water stains when needed and avoiding when not needed.

[0025] In some embodiments, the switching piece is an eccentric block, a ratchet or a magnetic attraction assembly.

[0026] The beneficial effect is that through the eccentric block, the ratchet or the magnetic attraction assembly, the function that the switching piece can be used to drive the entire mounting seat to switch between the first position and the second position can be realized, thereby realizing the scraping of water stains when needed and avoiding when not needed.

[0027] In some embodiments, the lower end of the scraping strip is a flexible piece.

[0028] The beneficial effect is that the lower end of the scraping strip is a flexible piece, which can make the scraping strip more closely contact with the surface to be cleaned, thereby better scraping water stains.

[0029] In some embodiments, the front end of the main body shell is provided with a receiving space, a roller brush is provided in the receiving space, and a scraper is provided at the front end of the receiving space.

[0030] Its advantages are: placing the squeegee at the front of the cleaning space makes it more convenient for users to use. When pushing the brush forward, the squeegee can be detached from the surface to be cleaned, thus avoiding water stains and only cleaning the surface. When pulling the brush backward, the squeegee can switch to contact the surface to be cleaned, thus creating a squeegee action and concentrating the water stains at the bottom of the cleaning space, making it easy to clean the concentrated water stains with the roller brush.

[0031] This patent also discloses a cleaning device, including the floor brush described above. It may also include a handle.

[0032] Its beneficial effect is that the cleaning device of this patent can simultaneously wipe dry the water stains on the surface to be cleaned while cleaning the surface. Attached Figure Description

[0047] As shown in the following: Figures 1-9

[0048] ​A floor brush, comprising a seat body 1, a mounting seat 2 and a scraping strip 3, the seat body 1 can be a main body shell of the floor brush, the mounting seat 2 is arranged on the seat body 1, and the scraping strip 3 is arranged on the mounting seat 2 and is as far as possible on the lower side of the mounting seat 2;

[0049] The mounting seat is provided with a first mounting part 21, the seat body is provided with a second mounting part 11, the first mounting part 21 and the second mounting part 11 are matched with each other to realize the rotatable connection between the mounting seat 2 and the seat body 1;

[0050] When the mounting seat 2 rotates on the seat body 1, the scraping strip 3 forms an angle with the surface to be cleaned, as shown in FIG. 7, the angle is calculated by taking the surface to be cleaned as the X axis and the angle between the straight line where the scraping strip is located and the X axis as the angle of the angle. Figure 4 、 6 The angle of the scraping strip and the surface to be cleaned ranges from 5 degrees to 180 degrees.

[0051] When the angle between the scraping strip 3 and the surface to be cleaned is the smallest, for example, 5 degrees, the mounting seat is located at the first position, and the lower end of the scraping strip 3 is in contact with the surface to be cleaned.

[0052] When the angle between the scraping strip 3 and the surface to be cleaned is the largest, for example, 180 degrees, the mounting seat is located at the second position, and the lower end of the scraping strip 3 is separated from the surface to be cleaned.

[0053] The beneficial effects are that the mounting seat 2 can rotate in the patent, so that the scraping strip can also rotate, and the scraping strip 3 and the surface to be cleaned can form an angle during the rotation. The scraping strip 3 is suspended on the mounting seat 2, and the angle is calculated by taking the rotation of the scraping strip towards the outside of the floor brush as the angle becoming smaller and smaller, and taking the rotation of the scraping strip towards the inside of the floor brush as the angle becoming larger and larger.

[0054] Therefore, when the angle between the scraping strip 3 and the surface to be cleaned is the smallest, the scraping strip 3 is rotated to the maximum position towards the outside of the floor brush, so that the lower end of the scraping strip is in contact with the surface to be cleaned, and the water stains on the surface to be cleaned are scraped clean.

[0055] When the angle between the scraping strip 3 and the surface to be cleaned is the largest, the scraping strip 3 is rotated to the maximum position towards the inside of the floor brush, so that the lower end of the scraping strip is separated from the surface to be cleaned, and the scraping strip 3 can no longer be in contact with the surface to be cleaned, so as to avoid the water stains on the surface to be cleaned. Therefore, when the scraping strip is in contact with the surface to be cleaned and the water stains are scraped back and forth, the water stains cannot be effectively removed.

[0056] In the patent, the lower end of the scraping strip 3 can be switched between the two positions of being in contact with the surface to be cleaned and being separated from the surface to be cleaned, that is, the scraping strip is not always in contact with the surface to be cleaned.

[0057] Preferably, the angle between the scraping strip 3 and the surface to be cleaned is between 80 degrees and 150 degrees.

[0058] As shown in Figure 4 , the lower end of the scraping strip 3 can be a soft part, when the mounting seat 2 is in the first position, the scraping strip 3 is in contact with the surface to be cleaned and is deformed in an arc shape, the angle is the angle α formed between the tangent at the contact point of the scraping strip and the surface to be cleaned and the surface to be cleaned, the angle α is between 5 degrees and 100 degrees. Of course, the entire scraping strip 3 can also be a hard scraping strip, and the corresponding angle is the angle formed between the straight line where the scraping strip is located and the surface to be cleaned.

[0059] Because the lower end of the scraping strip 3 is a soft part, when the scraping strip 3 is in contact with the surface to be cleaned, it can produce a fit similar to interference, that is, the scraping strip is in contact with the surface to be cleaned and is deformed in an arc shape, so that there will be a tangent at the contact point of the scraping strip and the surface to be cleaned, and the angle α formed between the tangent and the surface to be cleaned is between 5 degrees and 100 degrees, so that the scraping strip can form good close contact with the surface to be cleaned to achieve good water stain scraping effect.

[0060] As shown in Figure 6 , when the mounting seat 2 is in the second position, the angle is the angle β formed between the extension line of the end of the scraping strip 3 and the surface to be cleaned, and the angle β is between 95 degrees and 180 degrees, preferably between 115 degrees and 170 degrees.

[0061] The beneficial effect is that the scraping strip 3 is continuously rotated and retracted into the interior of the floor brush, when the mounting seat 2 is in the second position, that is, the lower end of the scraping strip is separated from the surface to be cleaned, at this time, the angle is the angle β formed between the extension line of the end of the scraping strip and the surface to be cleaned, and the angle β is between 95 degrees and 180 degrees, preferably between 115 degrees and 170 degrees. This angle cannot be too close to 90 degrees, for example, it is appropriate to be 150 degrees, in this case, if the surface to be cleaned has some large particles, if the angle β is too close to 90 degrees as shown in Figure 7 , the scraping strip 3 will be equivalent to a bulldozer, which will continuously roll the large particles forward and cannot be truly sucked into the interior of the floor brush. However, if the angle β is about 150 degrees, a close friction relationship can be formed between the large particles, the surface to be cleaned, and the scraping strip 3, so that under the action of friction, it is easier to enter the interior of the floor brush and thus be cleaned.

[0062] As shown in Figure 1 , 2 , 3, 5, in one embodiment, the first mounting part 21 is a rotating shaft, the second mounting part 11 is a mounting hole, the rotating shaft is inserted into the mounting hole, the rotating shaft is rotatably arranged in the mounting hole, a lubricant is arranged between the rotating shaft and the mounting hole, or the materials of the rotating shaft and the mounting hole are self-lubricating materials.

[0063] Through the cooperation of the rotating shaft and the mounting hole, the rotating shaft is a circular shaft, the mounting hole is a circular through hole or a counterbore, and the rotating shaft rotates in the mounting hole, so as to realize the rotary motion of the mounting seat and the scraping strip. In order to ensure better rotation effect, after setting the lubricant, the rotating shaft rotates in the mounting hole, which can reduce noise and resistance. Alternatively, the first mounting part is a rotating shaft, and the second mounting part can also adopt a bearing. The end of the rotating shaft is connected with the bearing, and the rotating shaft can rotate more smoothly through the bearing, thereby reducing noise and resistance. The lubricant can be selected from oil liquid lubricating oil, grease-like semi-solid lubricating grease, and solid lubricant.

[0064] As shown in Figure 8 , in another embodiment, the first mounting part 21 is a rotating shaft, and the second mounting part 11 can be a track groove. The rotating shaft can rotate and slide in the track groove.

[0065] After setting the track groove, the rotating shaft can rotate and slide in the track groove, thereby realizing the angle change of the scraping strip relative to the surface to be cleaned. So that the scraping strip switches between contacting and separating from the surface to be cleaned, thereby realizing effective removal of water stains.

[0066] The difference between the above two embodiments is that the position of the rotating shaft in the first embodiment is fixed and only rotates. The position of the rotating shaft in the second embodiment is changed, that is, the rotating shaft in the second embodiment rotates and changes position.

[0067] At the same time, as shown in Figure 1 , 2 , 3, 5, 8, a switching piece 4 is arranged on at least one end of the mounting seat 2. The switching piece 4 can be used to drive the entire mounting seat 2 to switch between the first position and the second position.

[0068] The beneficial effect is that through the switching piece 4, the mounting seat 2 can be conveniently switched between the first position and the second position, thereby realizing the contact or separation of the scraping strip 3 with the surface to be cleaned, thereby realizing the scraping of water stains when needed, and avoiding when not needed.

[0069] The switching element 4 can be selected from several options. The most convenient option is to set the switching element 4 as a component with high friction, such as an eccentric wheel block, and fix this switching element 4 to the mounting base 2. The switching element 4 includes a first end point and a second end point. In the first position, the position of the first end point is higher than the bottom end of the scraper 3, which allows the scraper 3 to deform slightly, thus making close contact with the surface to be cleaned and better removing water stains. After a certain rotation, the mounting base 2 will be in the second position, and the corresponding second end point can just contact the surface to be cleaned. At this time, the position of the second end point is at the bottom end of the scraper 3, which can suspend and support the scraper 3, thus allowing the lower end of the scraper 3 to detach from the surface to be cleaned.

[0070] Of course, the switch 4 can also be configured in various ways, such as as a ratchet or magnetic component.

[0071] like Figure 9 As shown, in another embodiment, the magnetic suction assembly can be achieved by mounting an electromagnet on the base and a magnet on the mounting base. This is implemented through circuit control. When water stains need to be scraped, the electromagnet is de-energized, causing the magnet on the mounting base 2 to separate from the electromagnet on the base 1. This allows the mounting base to rotate to a first position for scraping water stains. When scraping water stains is not needed, the electromagnet is energized, causing the electromagnet on the base 1 to attract the magnet on the mounting base. This allows the mounting base 2 to rotate to a second position, suspending the scraper 3 and detaching the lower end of the scraper from the surface to be cleaned.

[0072] Alternatively, in another embodiment, the switching element 4 can also be a ratchet. The ratchet can be a unidirectional rotating ratchet. When the scraper structure moves forward, the mounting seat can smoothly pass over the ratchet, thereby suspending the scraper 3 in the air and allowing the lower end of the scraper 3 to detach from the surface to be cleaned. When the scraper structure moves forward, the ratchet can block the mounting seat 2, thereby allowing the scraper to contact the surface to be cleaned, thus achieving the removal of water stains.

[0073] This patented floor brush can clean the surface to be cleaned while simultaneously wiping away water stains.

[0074] A receiving space 51 is provided at the front end of the main body shell, and a roller brush 52 is provided inside the receiving space 51. A scraper 3 is provided at the front end of the receiving space 51.

[0075] The scraper 3 is arranged at the front end of the containing space 51, which can be more convenient for the user to use the habit, when pushing the floor brush forward, the scraper 3 can be in a state of being separated from the surface to be cleaned, thereby avoiding water stains, and only cleaning the surface to be cleaned. When pulling the floor brush back, the scraper 3 can be switched to a state of being in contact with the surface to be cleaned, at which time a water stain scraping action can be formed, and the water stains can be concentrated and scraped to the lower side of the containing space 51, and finally the corresponding concentrated water stains can be conveniently cleaned by the roller brush 52.

[0076] As shown in Figure 10 The patent also discloses a cleaning device, which comprises the floor brush 5 as above, and a handle 6 for convenient handheld operation.

[0077] The beneficial effect is that the cleaning device of the patent can simultaneously scrape the water stains on the surface to be cleaned while cleaning the surface to be cleaned.

[0078] The above is only some embodiments of the present application, which is only used to illustrate the technical solutions of the present application, but not to limit it, and it should be understood that for those skilled in the art, without departing from the inventive concept of the present application, the above description can be improved or replaced, and all these improvements and replacements should belong to the protection scope of the appended claims of the present application. In this case, all details can be replaced by equivalent elements, and the materials, shapes and sizes can be arbitrary.
