Description

Technical Field

[0001] The utility model relates to the technical field of cleaning electrical appliances, in particular to a floor brush assembly and a cleaning machine. Background Art

[0002] As people's living standards improve, cleaning machines such as floor scrubbers are increasingly being used by people, improving their quality of life.

[0003] The basic working principle of floor scrubbers is that there is a button on the handle to control the switch. When the machine is started, the main working parts such as the suction fan, roller brush motor and water pump are started at the same time. The water pump sprays the water in the water tank onto the roller brush through the pipe. The roller brush is driven by the roller brush motor to rotate. After the roller brush is soaked in water, it drags the garbage on the ground to the suction port. The suction fan sucks the garbage into the sewage tank through the pipe. After cleaning, put the machine on the charging stand for self-cleaning, that is, the roller brush is cleaned when there is no garbage. After self-cleaning, it automatically enters the drying mode to dry the roller brush.

[0004] After using the floor scrubber for a long time, people will naturally feel a sense of frustration, that is, the floor brush assembly of the floor scrubber will vibrate up and down again and again, and observe the water stains during the forward push. It is found that there will be unevenly arranged water marks in the area where the floor scrubber passes. Under other unchanged conditions, the problem is improved after replacing the scraper bar. The root cause is the wear and tear of the scraper bar.

[0005] However, in the existing floor scrubbers, the scraping bar is integrated with the housing of the floor brush assembly of the floor scrubber, and it is too troublesome to replace the scraping bar. The user cannot manually replace the scraping bar, and the user experience is poor. Utility Model Content

[0006] In view of this, the utility model provides a floor brush assembly and a cleaning machine to solve the problem that users cannot conveniently replace the scraper strips.

[0007] In a first aspect, the utility model provides a floor brush assembly, comprising:

[0008] A shell, one side of which is connected to a roller brush, and a mounting portion is provided at the bottom of the shell near the roller brush;

[0009] The scraper strip is made of soft rubber material and is detachably connected to the mounting portion.

[0010] Beneficial effect: By setting a mounting portion on the shell, the scraper strip is detachably connected to the mounting portion. After the scraper strip has been used for a long time and is severely worn, the user can remove it from the shell according to actual needs and replace it with a new scraper strip, which is convenient to operate and improves the user experience.

[0011] In an optional embodiment, a first matching structure is provided on the mounting portion, and a second matching structure is provided on the scraper strip, and the second matching structure is snap-connected with the first matching structure.

[0012] Beneficial effect: By clamping the first matching structure and the second matching structure, the scraper strip can be detachably connected to the mounting portion, and the structure is relatively simple.

[0013] In an optional embodiment, the first matching structure is a slot, and the second matching structure is a protrusion.

[0014] In an optional embodiment, at least one end of the slot has an opening along the length direction.

[0015] Beneficial effect: By arranging an opening at at least one end of the card slot, the scraper strip can be installed into the card slot from the opening, which is convenient and quick.

[0016] In an optional embodiment, one end of the slot has the opening and the other end is closed.

[0017] Beneficial effect: By setting an opening at one end of the slot, it is convenient to assemble the scraper strip into the slot from the opening. At the same time, since the other end is closed, the scraper strip assembly can be further limited to prevent the scraper strip from shifting from the opening at the other end during assembly, and the scraper strip can be prompted to be in place. When the scraper strip is pushed from the opening at one end to the other end, when the scraper strip touches the other end, it means that the scraper strip has been assembled in place.

[0018] In an optional embodiment, an elastic member is fixedly connected to the groove bottom of the clamping groove, and is suitable for the elastic member to be located between the protrusion and the groove bottom when the scraper strip is assembled on the mounting portion.

[0019] Beneficial effect: By fixing the elastic part at the bottom of the slot, the elastic part can make the scraper have different compression amounts according to different pressures. When the compression amount of the scraper is smaller, it contacts more with the ground during operation and has better wiping effect, but the corresponding sense of frustration when pulling back is stronger. When the compression amount of the scraper is larger, the sense of frustration during operation is weaker, but the wiping effect will be affected. Therefore, by adjusting the compression amount of the scraper during use, it is possible to take into account both the wiping effect and the reduction of frustration, thereby improving the user experience.

[0020] In an optional embodiment, a supporting structure is provided at least at one end of the slot opening of the slot, the supporting structure extends from the slot opening in a direction away from the housing, and the supporting structure abuts against the scraper strip.

[0021] Beneficial effect: By arranging a supporting structure at the notch of the card slot, the supporting structure extends outward from the notch and abuts against the scraper strip, which can provide certain support for the scraper strip and prevent the scraper strip from being subjected to excessive force during use. This may cause a large gap to form at the joint between the scraper strip and the notch, which would cause water stains to remain in the gap and affect the cleaning effect.

[0022] In an optional embodiment, the scraper strip comprises:

[0023] A scraper body, the scraper body is suitable for scraping dirt, and the second matching structure is provided on a side of the scraper body close to the shell;

[0024] A connecting portion, disposed between the scraper strip body and the second matching structure;

[0025] The supporting structures are disposed at both ends of the notch, and the connecting portion is sandwiched between the two supporting structures. In an optional embodiment, along the thickness direction, the size of the connecting portion is smaller than the size of the second matching structure, and the size of the notch matches the size of the connecting portion.

[0026] Beneficial effect: By setting the size of the connecting part smaller along the thickness direction, setting the size of the second matching structure larger, and matching the size of the notch with the size of the connecting part, the slot can be clamped tighter to the second matching structure, preventing the scraper strip from falling off the slot during use.

[0027] In an optional embodiment, the first mating structure is provided with a first positioning structure, and the second mating structure is provided with a second positioning structure that is arranged to cooperate with the first positioning structure, which is suitable for the first positioning structure to be engaged with the second positioning structure when the first mating structure is engaged with the second mating structure.

[0028] Beneficial effect: By setting the first positioning structure on the first matching structure and the second positioning structure on the second matching structure, when the first matching structure is engaged with the second matching structure, the first positioning structure and the second positioning structure can be engaged, further improving the reliability of the connection between the scraper strip and the shell.

[0029] In a second aspect, the utility model further provides a cleaning machine, comprising: the above-mentioned floor brush assembly.

[0030] Beneficial effect: Because the cleaning machine includes the above-mentioned floor brush assembly, it has the same effect as the floor brush assembly and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0059] The basic working principle of floor scrubbers is that there is a button on the handle to control the switch. When the machine is started, the main working parts such as the suction fan, roller brush motor and water pump are started at the same time. The water pump sprays the water in the water tank onto the roller brush through the pipe. The roller brush is driven by the roller brush motor to rotate. After the roller brush is soaked in water, it drags the garbage on the ground to the suction port. The suction fan sucks the garbage into the sewage tank through the pipe. After cleaning, put the machine on the charging stand for self-cleaning, that is, clean the roller brush when there is no garbage. After self-cleaning, it automatically enters the drying function to dry the roller brush.

[0060] The inventor discovered during daily use and experimental verification that after a long period of use, people will naturally feel a sense of frustration in the floor scrubber, that is, the floor brush assembly of the floor scrubber will vibrate up and down again and again, and by observing the water stains during the forward push, it was found that unevenly arranged water marks will appear in the area where the floor scrubber passes.

[0061] The main reasons for the increase in water stains when the floor scrubber is pushed forward are as follows: First, the floor scrubber mainly relies on the scraper bar in the floor brush assembly to scrape water. When moving forward, the scraper bar fits the ground and scrapes the water stains on the ground by its own elastic force. However, after long-term use, the long-term friction between the scraper bar and the ground will cause the contact surface of the scraper bar to wear and the contact surface will no longer be flat, and water will leak from the uneven places. Second, the long-term reciprocating deformation of the scraper bar will reduce the elastic force of the scraper bar, the force of scraping water will become smaller, and the water stains after scraping will increase. The floor scrubber has a certain sense of frustration when pushing forward and backward. After long-term use, the original diameter of the roller brush has become thinner due to wear, causing the bottom shell of the floor scrubber to lower a certain distance, which further increases the compression of the scraper bar, and the scraper bar flips back and forth longer, causing a sense of frustration.

[0062] The inventor found that in other cases, the problem was improved by replacing the scraper bar, and the root cause was the wear of the scraper bar. However, in the existing floor scrubbers, the scraper bar and the housing of the floor brush assembly of the floor scrubber are integrated, and it is too troublesome to replace the scraper bar. Users cannot manually replace the scraper bar, and the user experience is poor.

[0063] Since the scraper strip generally includes a soft rubber part and a hard rubber part, the soft rubber part is used to contact the ground to scrape dirt, and the hard rubber part is fixedly connected to the bottom shell of the floor brush assembly by screws. In order to facilitate the disassembly of the scraper strip, the related art proposes to detachably connect the soft rubber part and the hard rubber part of the scraper strip, but this still makes the overall structure of the floor brush assembly larger in number, more complex in structure, higher in cost, and more times of assembly. Therefore, the applicant proposes a floor brush assembly to solve this problem.

[0064] Combine the following Figures 1 to 18 , describing an embodiment of the utility model.

[0065] According to an embodiment of the present utility model, on the one hand, a floor brush assembly is provided, comprising:

[0066] A housing 1, one side of the housing 1 is connected to a roller brush 3, and a mounting portion is provided at the bottom of the housing 1 near the roller brush 3;

[0067] The scraper strip 2 is made of soft rubber material and is detachably connected to the mounting portion.

[0068] By setting a mounting portion on the shell 1, the scraper strip 2 is detachably connected to the mounting portion. After the scraper strip 2 has been used for a long time and has been severely worn, the user can remove it from the shell 1 according to actual needs and replace it with a new scraper strip 2. The operation is convenient and the user experience is improved. At the same time, since the scraper strip 2 is made of soft rubber material, that is, it only includes a soft rubber part, and the scraper strip 2 is directly detachably connected to the mounting portion of the shell 1, the hard rubber part of the scraper strip 2 is eliminated, that is, only the soft rubber part of the scraper strip 2 is detachably connected to the shell 1, which reduces one component and reduces the cost. There is no need to assemble the soft rubber part with the hard rubber part first, and then assemble the scraper strip assembly with the soft rubber part and the hard rubber part with the shell 1 of the floor brush assembly 300, which reduces the number of assembly times for the user, makes it more convenient to use, and greatly improves the user experience.

[0069] There are many ways to detachably connect the scraper strip 2 and the mounting portion. In this embodiment, the mounting portion is provided with a first matching structure, and the scraper strip 2 is provided with a second matching structure 22, and the second matching structure 22 is engaged with the first matching structure. By engaging the first matching structure with the second matching structure 22, the scraper strip 2 can be detachably connected to the mounting portion, and the structure is relatively simple. As a convertible embodiment, the mounting portion and the scraper strip 2 can also be adhered together by double-sided adhesive. After the scraper strip 2 has been used for a period of time, the double-sided adhesive has basically reached the end of its service life, and it is also convenient for users to disassemble.

[0070] Specifically, Figure 5 As shown, the first matching structure in this embodiment is a slot 121, and the second matching structure 22 is a protrusion. As a changeable implementation, the first matching structure can also be a protrusion, and the second matching structure 22 can be a slot.

[0071] In the length direction, there is only one slot 121 and one protrusion, and both are in the shape of long strips. Figure 2 As a convertible implementation, a plurality of slots 121 and protrusions may be provided along the length direction, and the slots 121 and protrusions may be provided one by one.

[0072] like Fig. 9 and Fig.11As shown, along the length direction, one end of the slot 121 has an opening 1211 , and the other end is closed, that is, the other end is provided with an end wall, which is a closed end 1213 .

[0073] By setting an opening 1211 at one end of the slot 121, it is convenient to assemble the scraper strip 2 into the slot 121 from the opening 1211. At the same time, since the other end is closed, the scraper strip 2 can be further limited in assembly to prevent the scraper strip 2 from shifting from the opening at the other end during assembly, and the scraper strip 2 can be prompted to be assembled in place. When the scraper strip 2 is pushed from the opening 1211 at one end to the other end, when the scraper strip 2 touches the closed end 1213, it means that the scraper strip 2 has been assembled in place.

[0074] Of course, in other embodiments, both ends of the slot 121 may have openings 1211 along the length direction, so that the user can install the scraper strip 2 into the slot 121 from any opening 1211 , which is convenient and quick.

[0075] Of course, in other embodiments, the openings 1211 may not be provided at both ends of the slot 121 along the length direction, but the scraper strip 2 may be clamped into the slot 121 through the notch 1212 of the slot 121 by relying on the elastic deformation of the scraper strip 2, and after the scraper strip 2 is clamped into the slot 121, it is clamped in the slot 121 by the elastic force of the scraper strip 2.

[0076] In one embodiment, an elastic member may be fixedly connected to the bottom of the slot 121, so that when the scraper strip 2 is assembled on the mounting portion, the elastic member is between the protrusion and the bottom of the slot 121. Specifically, the elastic member is a spring. By fixing the elastic member to the bottom of the slot 121, the elastic member can make the scraper strip 2 have different compression amounts according to different pressures. When the compression amount of the scraper strip 2 is smaller, it contacts the ground more during operation, and the wiping effect is better. However, the corresponding sense of frustration during the backward conversion is stronger. When the compression amount of the scraper strip 2 is larger, the sense of frustration during operation is weaker, but the wiping effect will be affected. Therefore, by adjusting the compression amount of the scraper strip 2 during use, the wiping effect and the sense of frustration can be taken into account, thereby improving the user experience. As a convertible embodiment, it is also possible that the elastic member is not fixedly connected to the bottom of the slot 121, but the user replaces the scraper strip 2 with different compression amounts according to the actual use situation, that is, the scraper strip 2 with different widths can be replaced. The width here refers to Figure 7 When the user feels a strong sense of frustration and feels uncomfortable, it means that the roller brush 3 has been used for too long, causing the entire roller brush 3 to move downward. At this time, you can consider replacing a new roller brush 3 or replacing a scraper strip 2 with a lower width to reduce the frustration.

[0077] like Fig.12 As shown, the scraper strip 2 in this embodiment includes:

[0078] The scraper body 21 is suitable for scraping dirt, and a second matching structure 22 is provided on one side of the scraper body 21 close to the housing 1;

[0079] The connecting portion 23 is disposed between the wiper strip body 21 and the second matching structure 22 .

[0080] The slot 121 has support structures 122 at both ends of the slot 1212. The support structures 122 extend from the slot 1212 away from the housing 1 and abut against the connection portion 23 of the scraper strip 2. Specifically, the support structures 122 are support plates disposed at the upper and lower ends of the slot 1212.

[0081] By setting a supporting structure 122 at the notch 1212 of the card slot 121, the supporting structure 122 extends outward from the notch 1212 and abuts against the scraper strip 2, which can provide a certain support for the scraper strip 2 and prevent the scraper strip 2 from being subjected to excessive force during use. A large gap may be formed at the joint between the scraper strip 2 and the notch 1212, which would cause water stains and the like to remain in the gap and affect the cleaning effect.

[0082] As a convertible implementation, the support structure 122 may be provided only at one end of the notch 1212 of the slot 121 , such as only at the upper end or the lower end of the notch 1212 .

[0083] In the thickness direction, the size of the connecting portion 23 is smaller than that of the second matching structure 22, and the size of the notch 1212 matches that of the connecting portion 23, that is, the size of the notch 1212 is smaller than that of the groove bottom. The thickness direction here is the up-down direction.

[0084] By setting the size of the connecting portion 23 smaller and the size of the second matching structure 22 larger along the thickness direction, and matching the size of the notch 1212 with the size of the connecting portion 23, the slot 121 can be clamped tighter to the second matching structure 22, preventing the scraper strip 2 from falling off from the slot 121 during use.

[0085] like Fig. 9 and Fig.12 As shown, in this embodiment, a first positioning structure 123 is provided on the first matching structure, and a second positioning structure 221 is provided on the second matching structure 22 to match the first positioning structure 123, which is suitable for the first positioning structure 123 and the second positioning structure 221 to be clamped when the first matching structure and the second matching structure 22 are clamped.

[0086] By setting the first positioning structure 123 on the first matching structure and the second positioning structure 221 on the second matching structure 22, when the first matching structure is engaged with the second matching structure 22, the first positioning structure 123 and the second positioning structure can be engaged, further improving the reliability of the connection between the scraper strip 2 and the housing 1.

[0087] Specifically, the first positioning structure 123 is a through hole, and the second positioning structure 221 is a protrusion. When the first matching structure is engaged with the second matching structure 22, the first positioning structure 123 is just inserted into the second positioning structure 221. When the scraper strip 2 needs to be replaced, a screwdriver or other pointed object can be used to hold the second positioning structure 221 to remove it from the first positioning structure 123, and then the scraper strip 2 can be removed from the slot 121 by pulling it hard.

[0088] As a convertible embodiment, the first positioning structure 123 may be a protrusion and the second positioning structure 221 may be a through hole, or the first positioning structure 123 may be a buckle and the second positioning structure 221 may be a through hole or a slot, or the first positioning structure 123 may be a through hole or a slot and the second positioning structure 221 may be a buckle.

[0089] Among them, each of the first positioning structure 123 and the second positioning structure 221 is provided with one, and the first positioning structure 123 is provided at the end near the opening 1211 of the card slot 121. As a convertible implementation, the first positioning structure 123 can also be provided at other positions of the card slot 121. As a convertible implementation, multiple first positioning structures 123 and second positioning structures 221 are provided respectively along the length direction, and the first positioning structures 123 and the second positioning structures 221 are provided one by one.

[0090] like Fig.12 and Fig.15 As shown, the front wiping surface of the scraper body 21 in this embodiment has a triangular hook-shaped hook structure 211, whose function is that when the scraper 2 moves forward to wipe the water, the scraper 2 bends, and the triangular area of ​​the hook structure 211 just fits with the ground to wipe the ground.

[0091] A row of protrusions 212 are provided on the rear side of the scraper strip body 21, and multiple protrusions 212 are arranged at intervals along the length direction. The function of the protrusions 212 is to bend the scraper strip 2 upward when pulled back. The protrusions 212 play a supporting role, so that tiny garbage and water stains on the ground can pass through the scraper strip 2 without dragging the garbage and dirt to the rear side of the floor brush assembly 300.

[0092] like Fig.12 and Fig.15As shown, a clamping portion 24 extends upward from the connection between the scraper body 21 and the connection portion 23, and the clamping portion 24 is adapted to be clamped on the upper side of the support structure 122 after the support structure 122 abuts against the connection portion 23. The housing 1 of the floor brush assembly 300 in this embodiment is the bottom shell of the floor brush assembly 300.

[0093] like Figure 2 As shown, the housing 1 includes an upper housing 11 and a lower housing 12, the upper housing 11 is provided with a cover plate 13, and the lower housing 12 is provided with a scraper strip 2. A roller brush 3 is provided on one side of the housing 1, a rear wheel 5 is provided on the other side, and a small roller 4 is provided at the bottom of the lower housing 12. When there is no roller brush 3, if the user removes the old roller brush 3 and replaces the new roller brush 3, the small roller 4 and the rear wheel 5 can be used as support points to prevent other structural parts from contacting with the ground and causing friction and damaging the structural parts.

[0094] Since the scraper strip 2 in this embodiment is made of only soft rubber material and relies on its own elastic deformation force to fit with the suction port 6 of the lower shell 12, the hardness of the selected soft rubber material should not be too soft. The hardness of the material can be appropriately increased to improve the fit.

[0095] According to an embodiment of the present invention, on the other hand, a cleaning machine is provided, including: the above-mentioned floor brush assembly 300.

[0096] Specifically, the cleaning machine in this embodiment is a floor scrubber.

[0097] like Fig.17 and Fig.18 As shown, the floor scrubber includes a handle assembly 100, a body assembly 200 and a floor brush assembly 300 from top to bottom.

[0098] The basic working principle of the floor scrubber is that there is a button on the handle to control the switch. When the machine is started, the main working parts such as the suction fan, roller brush motor and water pump are started at the same time. The water pump sprays the water in the water tank onto the roller brush 3 through the pipeline. The roller brush 3 is driven by the roller brush motor to rotate. After the roller brush 3 is wetted with water, it drags the garbage on the ground to the sewage suction port 6. The suction fan sucks the garbage into the sewage tank through the pipeline.

[0099] When the floor scrubber moves forward, due to the weight of the floor scrubber, the scraper bar 2 will be bent backward by force, and the scraping surface of the scraper bar 2 will fit the ground. By using the elastic deformation force of the scraper bar 2, the scraper bar 2 will always be close to the ground to ensure that the water on the ground is scraped clean. When the floor scrubber moves backward, the scraper bar 2 will return to its original state, and the protrusions 212 on the back of the scraper bar 2 can penetrate some water stains and small garbage, and can absorb them when moving forward.

[0100] After the floor scrubber in this embodiment has been used for a long time, when the scraper bar 2 is worn out and the water stains on the floor increase, the user can replace the scraper bar 2 in time by himself / herself without going through after-sales channels or using it for a long time without replacement. In addition, by removing the hard plastic part of the scraper bar 2, the cost of the scraper bar 2 can be further reduced, thereby reducing the cost of the entire machine.

[0101] The floor scrubber in this embodiment tests the relationship between the wear of the roller brush 3 and the compression of the scraper strip 2 during use, and simultaneously tests the range of scraper strip compression within which a human body does not feel a sense of frustration. It is supported by various test data to ensure the user experience of different users and to ensure that the scraping condition is good.

[0102] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
