AI Technical Summary
Since the roller brushes of existing cleaning equipment always rotate in one direction, the ground-drag assembly must be thick enough to adapt, resulting in high manufacturing costs, high packaging costs, and difficult to extend into cleaning in a narrow space; at the same time, the roller brush cannot clean the problem that the dirty side of the gap is on the side of the rotation direction.
A rolling brush for cleaning equipment is designed, and a strip-shaped cleaning part formed of a plurality of bristles is fixedly provided on the shaft. When the shaft rotates, the cleaning part can swing and change the traditional 360° single-direction rotation method.
By changing the structure and cleaning method of the roller brush, the ground-drag assembly can be thinner, reduce manufacturing and packaging costs, and more easily extend into the cleaning in a narrow space; at the same time, the swinging action of the cleaning part can effectively clean up dirt regardless of its position, improving the cleaning effect.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of cleaning equipment, in particular to a cleaning equipment, a mopping component and a rolling brush. Background Art
[0002] Existing cleaning equipment such as floor scrubbers and vacuum cleaners have a mop assembly connected to their lower body. The mop assembly is provided with a receiving cavity for installing a roller brush, and the roller brush is driven to roll for cleaning by a driving assembly.
[0003] The roller brush of these cleaning devices always rotates in one direction when working, such as clockwise or counterclockwise. In order to avoid idleness, the peripheral wall of the roller brush is covered with bristles. When the roller brush rotates clockwise or counterclockwise, the bristles always keep in contact with the position to be cleaned to ensure cleaning efficiency. However, this also means that the accommodating cavity of the mop assembly must have sufficient depth (i.e., the thickness direction of the mop assembly) for the bristles to move, so that the mop assembly cannot be made very thin, resulting in high manufacturing and packaging costs. At the same time, when facing some narrow spaces, there is a problem that the mop assembly is too thick to be inserted into the space for cleaning.
[0004] On the other hand, since the roller brush always rotates clockwise or counterclockwise when working, when the dirt is on the side of the gap facing away from the rotation direction of the roller brush, the roller brush cannot clean it. Even if the mop assembly is dragged back and forth, it can only clean the dirt on the side of the gap facing the rotation direction of the roller brush, resulting in a poor cleaning effect. Utility Model Content
[0005] The main purpose of the utility model is to provide a cleaning device, a mopping assembly and a roller brush, aiming to solve the deficiencies in the related art.
[0006] To achieve the above object, the utility model provides a roller brush for cleaning equipment, comprising:
[0007] Rotating shaft;
[0008] A plurality of bristles are arranged on the peripheral wall of the rotating shaft, and the plurality of bristles are arranged to form a cleaning portion that is approximately in the shape of a long strip and extends along the length direction of the rotating shaft.
[0009] Preferably, the cross section of the rotating shaft is circular, semicircular or polygonal.
[0010] Preferably, the free end surface of the bristle is flat, pointed or spherical.
[0011] Preferably, two adjacent bristles are aligned with each other.
[0012] Preferably, two adjacent bristles are staggered with each other.
[0013] Preferably, one end of the bristles is directly fixedly connected to the peripheral wall of the rotating shaft, or a strip-shaped component fixed to the peripheral wall of the rotating shaft is further provided, and the bristles are fixed to the strip-shaped component.
[0014] Preferably, the strip-shaped member is detachably fixed to the peripheral wall of the rotating shaft by means of screw locking or a snap-fit structure.
[0015] The utility model also provides a floor mopping assembly, comprising:
[0016] case;
[0017] The roller brush described in any of the above embodiments, wherein the roller brush is rotatably mounted on the housing;
[0018] The motor has an actuator end connected to the roller brush and is used to drive the roller brush to rotate.
[0019] Preferably, the shell includes a base, a first upper cover and a second upper cover arranged on the base, the base is provided with a connected sewage extraction port and a receiving groove, the roller brush is rotatably installed in the receiving groove, the bottom of the receiving groove is open corresponding to the position of the roller brush and passes through the bottom of the base for the cleaning part to pass through, the second upper cover is arranged at the top of the base and covers the sewage extraction port, the first upper cover is arranged at a position adjacent to the second upper cover at the top of the base and covers the roller brush, and a cleaning structure is provided on the side of the first upper cover close to the roller brush for cleaning hair entangled on the cleaning part.
[0020] Preferably, the cleaning structure includes a plurality of comb teeth arranged on one side of the first upper cover close to the roller brush, and the plurality of comb teeth are spaced apart along the length direction of the roller brush. The spacing space between two adjacent comb teeth allows bristles at corresponding positions to pass through, and the comb teeth cooperate with each other to clean the hair entangled on the cleaning part during the passage of the bristles.
[0021] Preferably, a cone extending vertically is formed on the side of the comb teeth facing the rolling direction of the roller brush.
[0022] Preferably, the comb teeth and the first upper cover are an integrally formed structure or a detachable connection structure. When it is a detachable connection structure, the comb teeth are locked by screws or fixed to the first upper cover by a snap-fit structure.
[0023] The utility model also provides a cleaning device, comprising:
[0024] The roller brush as described in any one of the above embodiments;
[0025] Or, the mop assembly described in any one of the above embodiments;
[0026] When the rotating shaft of the roller brush rotates, the cleaning part can be driven to swing.
[0027] The technical solution provided by the embodiments of the present disclosure may have the following beneficial effects:
[0028] It can be seen from the above embodiments that the utility model has a cleaning portion fixedly arranged on the rotating shaft of the roller brush. The cleaning portion is a long strip formed by a plurality of bristles and extending along the length direction of the rotating shaft. When the rotating shaft rotates, the cleaning portion can be driven to swing. The roller brush of the existing cleaning equipment has a 360° rotation, which results in the floor mopping assembly having to be provided with a sufficient thickness to adapt thereto. Therefore, the floor mopping assembly cannot be made very thin. The utility model changes the structure and cleaning method of the roller brush, so that the roller brush itself can be made smaller, and the accommodating cavity for accommodating the roller brush is correspondingly smaller. Therefore, the floor mopping assembly can be made thinner, which is different from the traditional floor mopping assembly. The mop assembly has reduced its thickness by at least half, effectively reducing manufacturing costs and packaging costs. At the same time, when facing some narrow spaces, the mop assembly with a significantly reduced thickness can be easily inserted into the space for cleaning. On the other hand, when the roller brush of the utility model is working, its cleaning part repeatedly swings within a certain range, so that the dirt can be cleaned by the cleaning part no matter which side of the gap the dirt is in. Compared with the traditional single-direction rolling cleaning method, the cleaning effect is significantly improved, and when the roller brush adopts working mode 2 for cleaning, the cleaning part can be swung to be opposite to the sewage extraction port, so as to better suck the dirt during work.

[0036] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0037] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0038] In addition, if there are descriptions involving "first" or "second" etc. in the embodiments of the utility model, the descriptions of "first" or "second" etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
[0039] The utility model provides a roller brush.
[0040] In the embodiment of the utility model, Figure 1 As shown, the roller brush includes a rotating shaft 1 and a plurality of bristles 21 arranged on the peripheral wall of the rotating shaft 1 , wherein the plurality of bristles 21 are arranged to form a cleaning portion 2 that is substantially in the shape of an elongated strip and extends along the length direction of the rotating shaft 1 .
[0041] It should be noted that in other embodiments, the bristles 21 can also be replaced by objects with the same cleaning function, such as rags and brush bodies, and therefore should be considered equivalent. It should be noted that the bristles 21 are arranged on one side of the shaft 1 rather than the entire circle of the shaft 1. When the bristles 21 are vertically downward, the bristles 21 are not provided at least on the upper side of the shaft 1. In addition, the bristles 21 are arranged in a roughly long strip shape, that is, the edges of the long strips formed by their arrangement are not necessarily particularly neat or in a straight line, even if there is appropriate unevenness, and when the width of the arrangement of the bristles 21 (i.e., the angle across the shaft 1) is large, the fan-shaped strips presented on the shaft 1 are also the above-mentioned long strips. When in use, the cleaning part 2 cooperates with the drive of the shaft 1 to make a swinging motion, and the bristles 21 are only available for swinging in the lower space of the shaft 1. Therefore, no or only a small space is required on the upper side of the shaft 1. In this way, when the roller brush is used in cleaning equipment, it helps to reduce the vertical height of the roller brush installation position on the equipment.
[0042] Specifically, the cross-section of the rotating shaft 1 is circular, semicircular or polygonal. Compared with the traditional roller brush that is covered with bristles all over, the cross-section of the rotating shaft of the traditional roller brush is usually set to be circular to facilitate the arrangement of bristles all over the body; the roller brush of the utility model is only provided with a long strip of bristles on the rotating shaft 1, so that the cross-sectional shape of the rotating shaft 1 has more choices. In specific applications, the designer can choose a suitable shape of the rotating shaft 1 according to the characteristics of the product. For example, in order to minimize the occupied space, the rotating shaft 1 with a semicircular cross-section of the same size is better than the rotating shaft 1 with a circular cross-section; when the number and arrangement of bristles 21 are the same, the rotating shaft 1 with a polygonal cross-section saves more space than the rotating shaft 1 with a circular cross-section. Of course, the above list does not represent all the situations considered when selecting the rotating shaft 1. Those skilled in the art can make other choices according to actual conditions to meet the rotating shaft 1 for the purpose of maximizing the reduction of occupied space.
[0043] Specifically, the free end surface of the bristle 21 is flat, pointed or spherical, so as to improve the cleaning effect.
[0044] In one embodiment, two adjacent bristles 21 are aligned with each other.
[0045] In another embodiment, two adjacent bristles 21 are staggered with each other.
[0046] It should be noted that the alignment between the two adjacent bristles 21 means that the bristles 21 of the cleaning part 2 are arranged in a row at a certain interval in the horizontal and vertical directions; the staggered between the two adjacent bristles 21 includes that the bristles 21 of the cleaning part 2 are arranged in a row at a certain interval in the horizontal direction and staggered in the vertical direction, or the bristles 21 of the cleaning part 2 are arranged in a row at a certain interval in the vertical direction and staggered in the horizontal direction, or the bristles 21 of the cleaning part 2 are staggered in an irregular arrangement in the horizontal and vertical directions. It can be understood that when the spacing is the same, the staggered setting between the bristles 21 can provide a greater bristle density than the setting of the alignment between the bristles 21, so it is more suitable for cleaning fine and dirty surfaces, such as surfaces with a lot of dust; on the contrary, the bristle density of the roller brush is smaller, and it is more suitable for cleaning larger dirty surfaces. At this time, there are more bristles at the same position, which can provide greater cleaning power, such as surfaces with a lot of sawdust and sand.
[0047] In one embodiment, one end of the bristles 21 is directly fixedly connected to the peripheral wall of the rotating shaft 1, and the purpose of replacing the brush with a new one can be achieved by replacing the roller brush.
[0048] In another embodiment, a strip member fixed to the peripheral wall of the rotating shaft 1 is further provided, and a number of the bristles 21 are fixed to the strip member. The strip member may be permanently fixed to the rotating shaft 1 or detachably fixed to the rotating shaft 1. When the strip member is permanently fixed to the rotating shaft 1, the purpose of providing the strip member is to facilitate the fixation of the bristles 21 (because it is usually not easy to directly fix the bristles 21 to the rotating shaft 1). In this case, the strip member may be fixed to the rotating shaft 1 by pasting; when the strip member is detachably fixed to the rotating shaft 1, the purpose of providing the strip member also includes a replaceable strip member to reduce the maintenance cost of the roller brush. For example, in some embodiments, the detachable fixation of the strip member includes the strip member being detachably fixed to the peripheral wall of the rotating shaft 1 by screw locking or by a snap-on structure, thereby realizing the replaceable function of the bristles 21 to reduce the maintenance cost of the roller brush.
[0049] It should be noted that the clamping structure can refer to the prior art, and its specific structural principle will not be described in detail here.
[0050] The utility model also provides a floor mopping assembly, such as Figures 2 to 7 As shown, it includes a housing, a motor and a roller brush, the roller brush is rotatably mounted on the housing, and the execution end of the motor 3 is connected to the roller brush to drive the roller brush to rotate. The roller brush can refer to the above embodiment. Since the floor mopping assembly adopts all the technical solutions of all the embodiments of the above roller brush, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.
[0051] Specifically, the housing includes a base 41, a first upper cover 42 and a second upper cover 43 provided on the base 41, the base 41 is provided with a connected sewage extraction port 44 and a receiving groove 45, the roller brush is rotatably installed in the receiving groove 45, the bottom of the receiving groove 45 is open corresponding to the position of the roller brush and penetrates the bottom of the base 41 for the cleaning part 2 to pass through, the second upper cover 43 is provided on the top of the base 41 and covers the sewage extraction port 44, the first upper cover 42 is provided at a position adjacent to the second upper cover 43 on the top of the base 41 and covers the roller brush, and a cleaning structure is provided on the side of the first upper cover 42 close to the roller brush for cleaning the hair entangled on the cleaning part 2. Among them, the way of covering the sewage extraction port 44 and the roller brush by the first upper cover 42 and the second upper cover 43 respectively is conducive to installation and disassembly. For example, when it is necessary to take out the roller brush or clean the cleaning structure, the first upper cover 42 can be removed separately to perform the corresponding operation, and the first upper cover 42 and the second upper cover 43, which occupy a small space, are also convenient for cleaning, packaging, storage, etc.
[0052] Specifically, the cleaning structure includes a plurality of comb teeth 51 arranged on one side of the first upper cover 42 close to the roller brush, and the plurality of comb teeth 51 are spaced apart along the length direction of the roller brush. The space between two adjacent comb teeth 51 allows the bristles 21 at corresponding positions to pass through, and the comb teeth 51 cooperate with the brush to clean the hair entangled on the cleaning part 2 during the passage of the bristles 21.
[0053] Specifically, a cone portion 52 extending vertically is formed on one side of the comb teeth 51 facing the rolling direction of the roller brush.
[0054] Specifically, the comb teeth 51 and the first upper cover 42 are an integrally formed structure or a detachable connection structure. When it is a detachable connection structure, the comb teeth 51 are locked by screws or fixed to the first upper cover 42 by a snap-fit structure.
[0055] It should be noted that the buckle structure can refer to the prior art, and its specific structural principle will not be described in detail here.
[0056] The utility model also provides a cleaning device, including a roller brush or a mop assembly, wherein the rotating shaft 1 of the roller brush can drive the cleaning part 2 to swing when rotating. The roller brush or the mop assembly can refer to the above embodiments. Since the cleaning device adopts all the technical solutions of all the embodiments of the roller brush or the mop assembly, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
[0057] It should be noted that the cleaning device can be a vacuum cleaner or a floor scrubber, which mainly includes a body and a mopping assembly. The related structures not mentioned in this article can directly refer to the prior art, and its specific structural principles will not be repeated here.
[0058] The cleaning method of the cleaning device of the present utility model is mainly realized by the working mode of the roller brush in the above embodiment. The method includes driving the roller brush to work to clean the surface to be cleaned. The roller brush includes one or more of the following working modes:
[0059] Method 1: The cleaning part 2 is perpendicular to the top of the surface to be cleaned and repeatedly swings within a range where the sum of the clockwise direction and the counterclockwise direction is equal to 90° or less than 90°;
[0060] Method 2: The cleaning part 2 is perpendicular to the top of the surface to be cleaned and repeatedly swings within a range where the sum of the clockwise direction and the counterclockwise direction is greater than 90° and less than 180°;
[0061] Method 3: The cleaning part 2 rotates 360° counterclockwise;
[0062] Method 4: A combination of the method 1 and the method 3, or a combination of the method 2 and the method 3.
[0063] It should be noted that the difference between the method 1 and the method 2 is that the cleaning part 2 swings at a different angle, wherein the cleaning part 2 swings at a larger angle in the method 2, which increases the travel of the cleaning part 2 away from the surface to be cleaned, making it easier to raise dust and suck dirt stuck on the cleaning part 2. Therefore, in the present cleaning method, when the working mode of the roller brush includes a combination of the method 1 and the method 2, it can be designed to allow the user to select the working mode of the method 1 or the method 2.
[0064] It should be noted that the purpose of the method three is to use the cleaning structure to clean the hair entangled in the cleaning part 2. Therefore, this working method can be embedded in the cleaning process and used in conjunction with methods one and two, and can also be used to clean the roller brush alone when the equipment is parked after cleaning.
[0065] It should be noted that in the fourth mode, the combination of the first mode and the third mode includes the cleaning part 2 repeatedly swinging a set number of times, and then rotating 360° in the counterclockwise direction once or multiple times, and so on, or the cleaning part 2 repeatedly swings a set time, and then rotates 360° in the counterclockwise direction once or multiple times, and so on, or the cleaning part 2 repeatedly swings until the last time or the last multiple times before the cleaning stops are 360° in the counterclockwise direction. It is understandable that the specific content of the combination of the first mode and the third mode is different from the combination of the first mode and the third mode only in the swing angle of the cleaning part 2, so it is not repeated here.
[0066] The cleaning method of the cleaning device is that when the roller brush is working, its cleaning part swings repeatedly within a certain range, and the dirt can be cleaned by the cleaning part no matter which side of the gap it is in. Compared with the traditional single-direction rolling cleaning method, the cleaning effect is significantly improved.
[0067] It can be seen from the above embodiments that the utility model has a cleaning portion fixedly arranged on the rotating shaft of the roller brush. The cleaning portion is a long strip formed by a plurality of bristles and extending along the length direction of the rotating shaft. When the rotating shaft rotates, the cleaning portion can be driven to swing. The roller brush of the existing cleaning equipment has a 360° rotation, which results in the floor mopping assembly having to be provided with a sufficient thickness to adapt thereto. Therefore, the floor mopping assembly cannot be made very thin. The utility model changes the structure and cleaning method of the roller brush, so that the roller brush itself can be made smaller, and the accommodating cavity for accommodating the roller brush is correspondingly smaller. Therefore, the floor mopping assembly can be made thinner, which is different from the traditional floor mopping assembly. The mop assembly has reduced its thickness by at least half, effectively reducing manufacturing costs and packaging costs. At the same time, when facing some narrow spaces, the mop assembly with a significantly reduced thickness can be easily inserted into the space for cleaning. On the other hand, when the roller brush of the utility model is working, its cleaning part repeatedly swings within a certain range, so that the dirt can be cleaned by the cleaning part no matter which side of the gap the dirt is in. Compared with the traditional single-direction rolling cleaning method, the cleaning effect is significantly improved, and when the roller brush adopts working mode 2 for cleaning, the cleaning part can be swung to be opposite to the sewage extraction port, so as to better suck the dirt during work.
[0068] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
