Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, and in particular relates to a new type of floor scrubber. Background Technology

[0002] A floor scrubber is a cleaning device suitable for cleaning hard floors while simultaneously sucking up and removing wastewater from the site. Most existing floor scrubbers are structurally similar to the household floor scrubber submitted in the utility model patent application number 202120921534.3. They mainly include a handle and body (composed of a handle and the main body of the floor scrubber) and a floor brush. The handle and body are connected to the floor brush and have a built-in clean water tank, a suction motor, and a wastewater tank. The clean water tank supplies water to the floor brush to scrub the floor, and the suction motor generates negative pressure to suck the wastewater on the floor into the wastewater tank to complete the floor cleaning operation. The operation is relatively simple.

[0003] However, in actual use, it was found that the wastewater tank and clean water tank are fixedly installed on the handle body, which makes the handle body too heavy and the overall center of gravity too high, making it more difficult for users to operate and increasing arm fatigue. At the same time, it also makes the handle body too thick, which makes it difficult for the floor brush to flexibly enter under low furniture, thus limiting the cleaning area and affecting the user experience. Utility Model Content

[0007] Preferably, the hidden cavity has a movable opening on its side, through which the clean water tank can enter and exit the hidden cavity. A valve with a rubber block and a water passage is movably installed at the water outlet of the clean water tank. When the clean water tank is full, water pressure drives the valve to move, causing the rubber block to abut and close the water outlet. When the clean water tank enters the hidden cavity, the connecting end is inserted into the water outlet and moves against the valve, causing the rubber block to move away from the water outlet, thereby ensuring that the connecting end can connect to the inside of the clean water tank via the water passage.

[0008] Preferably, the wastewater tank is located at the bottom of the machine body, and a guide plate is installed on the top of the wastewater tank. The guide plate has an opening at its center that connects the wastewater tank to the outside. The guide plate gradually recesses towards the opening from its edge to form a flow guiding area. The scraper is located at the edge of the guide plate and extends along the length of the roller brush. The scraper also abuts against the roller brush at an angle to smoothly guide the wastewater and debris scraped off the roller brush into the flow guiding area.

[0009] Preferably, the scraper is further connected to a scraper blade, which extends along the length of the roller brush and is offset from the roller brush, and the scraper blade also contacts the ground synchronously with the roller brush.

[0010] Preferably, the sewage tank has multiple insertion blocks on its side, and each insertion block has a locking hole at its bottom; the scraper has multiple insertion holes arranged in a straight line along its length, and each insertion hole has a locking block at its inner bottom; wherein, the multiple locking blocks can engage with the multiple locking holes one by one, and the multiple insertion blocks can be inserted into the multiple insertion holes one by one, so that the scraper and the sewage tank are detachably connected.

Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0019] See appendix Figure 1 -Appendix Figure 9 A novel floor scrubbing machine includes a body 1, a water supply unit 2, and a wastewater recovery unit 3. The top of the body 1 is hinged with a multi-angle swing handle 11, and the bottom of the body 1 is equipped with a rotatable roller brush 12. The water supply unit 2 includes a clean water tank 21 and a water delivery unit 22. Both the clean water tank 21 and the water delivery unit are installed on the body 1, and the water delivery unit 22 is connected to the clean water tank 21 and designed to correspond to the roller brush 12, so as to deliver the water in the clean water tank 21 to the roller brush 12. The wastewater recovery unit 3 includes a wastewater tank 31 and a scraper 32. The wastewater tank 31 is detachably installed on the body 1, and the scraper 32 is installed on the wastewater tank 31 and abuts against the roller brush 12, so as to scrape the wastewater and debris adsorbed on the roller brush 12 into the wastewater tank 31.

[0020] Specifically, during use, the handle 11 is held to bring the roller brush 12 into contact with the ground. Then, water or cleaning solution from the water tank 21 is delivered to the roller brush 12 through the water supply unit 22, making the roller brush 12 wet. At this time, the roller brush 12 is driven to rotate, which can effectively scrub and absorb dust, hair and other debris on the ground to complete the floor cleaning. During the cleaning process, the rotating roller brush 12 will carry the absorbed debris and wastewater to the scraper 32. Under the action of the scraper 32, the wastewater and debris absorbed on the roller brush 12 will be scraped into the wastewater tank 31 as the roller brush 12 rotates, thus completing the recycling of wastewater and debris and cleaning the roller brush 12, making it convenient to continue scrubbing the ground.

[0021] Since the wastewater tank 31 and the clean water tank 21 are located on the machine body 1, the overall center of gravity is lower, which can save physical strength. When cleaning the ground under low furniture, the handle rod 11 can be swung to make a small angle between it and the machine body 1, so that it can be inserted under the low furniture for cleaning.

[0022] It should be noted that the roller brush 12 can be directly rotatably connected to the body 1, so that the roller brush 12 can be rotated by the friction between the roller brush 12 and the ground during the process of pushing the body 1. Of course, a drive motor (not shown in the figure) can also be set inside the body 1 to drive the roller brush 12 to rotate automatically. In this case, the user only needs to control the direction of movement through the handle 11. The manufacturer can set the rotation mode of the roller brush 12 to be manually driven or electrically driven as needed. This utility model does not limit this. On the other hand, regarding the hinge method between the handle and the body 1, a conventional swing connection or a ball joint hinge can be used, so that there are multiple angles of movement between the two. Since the relevant hinge methods are diverse and relatively conventional, this utility model does not limit this.

[0023] In summary, by placing the wastewater tank 31 and the clean water tank 21 on the machine body 1, this floor scrubber lowers the overall center of gravity, making it easier for users to operate and saving physical effort, thus reducing arm fatigue. It also avoids the bulkiness of the handle 11, ensuring that users can easily adjust the angle between the handle 11 and the machine body 1, improving the flexibility of the floor brush and expanding the cleaning area to ensure a better user experience. In addition, by using the scraper 32 in conjunction with the rotating roller brush 12, wastewater can be recycled without the need for a suction motor, effectively reducing manufacturing costs.

[0024] See appendix Figure 5 -Appendix Figure 8 The top of the body 1 is provided with a hidden cavity 13 for accommodating the clean water tank 21. The clean water tank 21 is provided with a water outlet 211 and a water inlet 212 that protrudes from the hidden cavity 13 and is covered with a cover 2120. The water supply unit 22 includes a connecting end 221, a water pump 222 and a spray pipe 223. The connecting end is installed on the body 1 and is inserted into the water outlet 211. The spray pipe 223 is installed on the body 1 and has multiple spray holes 2230 corresponding to the roller brush 12. The water pump 222 is installed inside the body 1, and the water pump 222's suction end is connected to the connecting end 221 through a water pipe (not shown in the figure). The water pump 222's discharge end is connected to the spray pipe 223 through a water pipe (not shown in the figure) to pump the water in the clean water tank 21 to the spray holes 2230 to spray the roller brush 12.

[0025] Specifically, during use, first remove the cover 2120 to open the water inlet 212, and inject clean water or cleaning solution into the clean water tank 21 through the water inlet 212. Then close the cover 2120 to close the water inlet 212. Next, start the water pump 222 to pump the water in the clean water tank 21 to the spray pipe 223, so that the water is sprayed out from the spray hole 2230 to wet the roller brush 12 for cleaning. After cleaning, turn off the water pump 222 to cut off the water flow channel between the clean water tank 21 and the spray pipe 223. The hidden cavity 13 can prevent the clean water tank 21 from being exposed and make the overall structure more compact, preventing the machine body from being too bulky. By using the water pump 222 and the spray pipe 223 together, the water can be sprayed more evenly onto the roller brush 12.

[0026] It should be noted that the specific structure of the nozzle 223 varies, and not all of them will be listed in this utility model. For ease of understanding, in this embodiment, the nozzle 223 is provided with a liquid flow channel 2231 that simultaneously connects to multiple nozzle holes, and the nozzle 223 is provided with a water inlet end 2232 that connects to the liquid flow channel 2231. The water inlet end 2232 is connected to a water pipe installed at the drain end of the water pump 222. On the other hand, regarding the power supply of the water pump 222, a built-in battery can be used for power supply in the body 1 or the handle 11. Since the relevant technology is relatively conventional in the field, it will not be described in detail in this embodiment.

[0027] See appendix Figure 5 -Appendix Figure 8 The hidden cavity 13 has a movable opening 130 on its side, through which the clean water tank 21 can enter and exit the hidden cavity 13. A valve 213 with a rubber block 2131 and a water passage 2132 is movably installed at the water outlet 211 of the clean water tank 21. The connecting end 221 can be inserted into the water outlet 211 and abut against the valve 213 as the clean water tank 21 moves inward.

[0028] Specifically, when the water tank 21 is full, the valve 213 moves outward under water pressure, causing the rubber block 2131 to abut and close the water outlet 211. When the water tank 21 is moved into the hidden cavity 13, the connecting end 221 is inserted into the water outlet 211 and moves against the valve 213, so that the rubber block 2131 moves away from the water outlet 211. At this time, the water channel 2132 connects the inside of the water tank 21 and the connecting end 221, thereby ensuring that the water pump 222 can smoothly pump water to the spray pipe 223. The design of the movable port 130 facilitates the disassembly and maintenance of the water tank 21, while the design of the valve 213 can close the water outlet 211, preventing the water in the water tank 21 from overflowing and affecting its use before the connecting end 221 is inserted into the water outlet 211.

[0029] See appendix Figure 5 -Appendix Figure 8The inner wall of the concealed cavity 13 is provided with a protrusion 13t extending along the direction of the movable opening 130. The outer wall of the clean water tank 21 is also provided with a groove 21t that is slidably connected to and interference-fitted with the protrusion 13t. This design gives the clean water tank 21 sliding damping, preventing the clean water tank 21 from easily detaching from the concealed cavity 13 and improving installation stability. In addition to the above structure, a snap-fit ​​structure, a magnetic structure, or direct screw fixing can also be provided between the clean water tank 21 and the body 1. Since there are various fixing methods, this invention and utility model do not limit this.

[0030] See appendix Figure 9 -Appendix Figure 12 The sewage tank 31 is located at the bottom of the body 1, and a guide plate 33 is installed on the top of the sewage tank 31. The guide plate 33 has an opening 331 in the center that connects the sewage tank 31 to the outside. The guide plate 33 gradually recesses towards the opening 331 from the edge to form a guide area 332. The scraper 32 is located at the edge of the guide plate 33 and extends along the length of the roller brush 12. The scraper 32 also abuts against the roller brush 12 at an angle.

[0031] Specifically, during the cleaning process, the rotating roller brush 12 carries the adsorbed sewage and impurities to the scraper 32. The scraper 32 can smoothly scrape off the sewage and debris on the roller brush 12. Under the action of its own gravity, the scraped sewage and debris enter the guide area 332 along the scraper 32, and under the guidance of the guide area 332, they converge into the sewage tank 31 through the outlet 331. Therefore, the above structural design can thoroughly clean the roller brush 12 and guide sewage and debris into the sewage tank 31, which can reduce the possibility of sewage overflow and further improve the user experience.

[0032] See appendix Figure 9 -Appendix Figure 12 The scraper 32 is also connected to a scraper blade 320. The scraper blade 320 extends along the length of the roller brush 12 and is offset from the roller brush 12. The scraper blade 320 also contacts the ground synchronously with the roller brush 12. The scraper blade 320 can be used to loosen large stains on the ground, so that the stains can be rolled away by the roller brush 12, thereby further improving cleaning efficiency.

[0033] See appendix Figure 12 -Appendix Figure 15The sewage tank 31 has multiple insert blocks 311 on its side, and each insert block 311 has a locking hole 312 at its bottom. The scraper 32 has multiple insert holes 321 arranged in a straight line along its length, and each insert hole 321 has a locking block 322 at its inner bottom. The multiple locking blocks 322 can engage with the multiple locking holes 312 one by one, and the multiple insert blocks 311 can be inserted into the multiple insert holes 321 one by one. This design allows the scraper 32 to be detachably connected to the sewage tank 31, making it convenient for users to replace and clean the scraper 32. In addition to the above structure, other detachable installation methods can also be used between the scraper 32 and the sewage tank 31. Since there are many methods, this invention and utility model do not limit them.

[0034] See appendix Figure 1 -Appendix Figure 15 Two roller brushes 12 are provided and distributed on two opposite sides of the machine body 1, and two scraper blades 32 are provided and distributed on two opposite sides of the sewage tank 31. The two scraper blades 32 are designed to correspond one-to-one with the two roller brushes 12. For ease of understanding, the two roller brushes 12 are referred to as the first roller brush and the second roller brush, and the two scraper blades 32 are referred to as the first scraper blade and the second scraper blade. In this case, there are two different cases as follows: In Case 1, when no drive motor (not shown in the diagram) is installed to rotate the roller brush 12, if it is necessary to control the machine body 1 to move forward, the handle is moved and the friction of the ground drives the first and second roller brushes to rotate counterclockwise simultaneously. At this time, the first roller brush is mainly used to scrub the ground, and the debris it adsorbs is scraped off by the first scraper and falls to the ground, and will not directly enter the wastewater tank 31. The second roller brush is used to adsorb the wastewater and debris remaining on the scrubbed ground, and to carry the wastewater and debris to the second scraper for scraping. The wastewater and debris are collected into the wastewater tank 31. If the control body 1 moves backward, the handle lever is moved and the first and second roller brushes are driven to rotate clockwise simultaneously by the friction of the ground. At this time, the second roller brush is mainly used to scrub the ground, and the debris it adsorbs is scraped off by the second scraper and falls to the ground. It will not directly enter the wastewater tank 31. The first roller brush is used to adsorb the wastewater and debris remaining on the scrubbed ground and carry the wastewater and debris to the first scraper for scraping, so that the wastewater and debris are collected into the wastewater tank 31.

[0035] In Case 2, when two drive motors (not shown in the diagram) are used to drive two root brushes 12 to rotate relative to each other, the torque difference between the two motors needs to be adjusted to control the forward and backward movement of the machine body 1. If the machine body 1 needs to be moved forward, the torque of the drive motor used to control the rotation of the second brush needs to be adjusted to be greater than the torque of the drive motor used to control the rotation of the first brush, so as to ensure that the machine body 1 can move forward automatically. If the machine body 1 needs to be moved backward, the torque of the drive motor used to control the rotation of the second brush needs to be adjusted to be less than the torque of the drive motor used to control the rotation of the first brush, so as to ensure that the machine body 1 can move backward automatically.

[0036] Manufacturers can select appropriate cases to produce corresponding products according to user needs, and this utility model does not impose any restrictions on this.

[0037] See appendix Figure 4 -Appendix Figure 6 and attached Figure 15 The bottom of the sewage tank 31 is also equipped with multiple rotatable pulleys 313. Each pulley 313 contacts the ground synchronously with the roller brush 12. This design can reduce the friction between the machine body 1 and the ground, increase the mobility of the machine body 1, and further improve the user experience.

[0038] See appendix Figure 6 -Appendix Figure 12 The bottom of the machine body 1 is provided with a guide rail 14, which is located next to the roller brush 12 and extends along the length of the roller brush 12; the sewage tank 31 is provided with a guide block 314 and a locking mechanism 4, the guide block 314 is slidably engaged with the guide rail 14, and the locking mechanism 4 is used to drive the sewage tank 31 to lock or loosen the machine body 1.

[0039] Specifically, when the sewage tank 31 needs to be installed, move the sewage tank 31 inward along the guide rail 14 so that the scraper 32 is aligned with the roller brush 12 and installed in place. Then, lock the sewage tank 31 onto the machine body 1 using the locking mechanism 4. When the sewage tank 31 needs to be disassembled, first release the restriction of the locking mechanism 4 on the sewage tank 31, and then move the sewage tank 31 outward along the guide rail 14. This design allows the sewage tank 31 and the machine body 1 to be disassembled from each other, making it convenient for users to disassemble the sewage tank 31 for cleaning and maintenance.

[0040] See appendix Figure 6 -Appendix Figure 13 The inner wall of the body 1 has an opening 15 that connects to the outside, and the body 1 has a locking position 150 next to the opening 15. The sewage tank 31 is equipped with a baffle 315, and the baffle 315 has a fixing block 3151 with an adjustment groove 3152. The locking mechanism 4 includes a button 41, a buckle 42 and an elastic element 43. One end of the button 41 is placed in the adjustment groove 3152 and is rotatably connected to the fixing block 3151. The other end of the button 41 is fixed to the buckle 42 located outside the adjustment groove 3152 and corresponding to the locking position 150. The elastic element 43 is set in the adjustment groove 3152 and abuts against the bottom wall of the adjustment groove 3152 and the button 41 respectively.

[0041] Specifically, when installing the wastewater tank 31, first press the button 41 to cause the elastic element 43 to deform and store energy, and move the wastewater tank 31 inward along the guide rail 14 so that the baffle 315 abuts against the side wall of the machine body 1, so that the button 41 is inserted into the notch 15 and the buckle is aligned with the locking position 150. Then, release the button 41, the elastic element 43 releases energy and returns to its original state, and applies pressure to the button 41 to drive the buckle 42 to engage with the locking position 150 and lock the wastewater tank 31 onto the machine body 1. When removing the wastewater tank 31, first press the button 41. Drive the buckle 42 to disengage from the locking position 150, and then move the sewage tank 31 outward along the guide rail 14; the design of the baffle 315 can provide the user with a point of leverage to facilitate the user's movement of the sewage tank 31, and can also indicate to the user that the sewage tank 31 is installed in place when it comes into contact with the machine body 1, thus improving the ease of operation; in addition, the elastic element 43 can be made of rubber strips, springs, etc., and the locking mechanism 4 can also adopt other structures in addition to the above-mentioned structures. Due to the variety of related structures, no restrictions are placed on this invention and utility model.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
