Description

Technical Field

[0001] The utility model belongs to the technical field of surface cleaning equipment, and particularly relates to a comb-tooth scraping strip and a floor mopping assembly thereof. Background Art

[0002] The floor scrubber is a new type of floor cleaning equipment in recent years. It generally consists of three parts: a handle, a body, and a mop. The mop is parked on the ground, and the user manipulates the body through the handle to drive the mop to move back and forth on the ground to achieve the effect of cleaning the ground. The mop is usually equipped with a roller brush. When working, the roller brush rotates, and clean water is sprayed on the rotating roller brush. The rotating wet roller brush is used to scrub the ground, and the sewage and dirt after cleaning are sucked away through the suction mechanism. When there is hair on the ground to be cleaned, these hairs will be entangled on the roller brush and cannot be sucked away. Eventually, more and more hair will accumulate, causing the roller brush to jam.

[0003] In order to solve the above problem, the commonly used method is to set a row of saw teeth next to the roller brush, such as the scraping strip, roller brush assembly and cleaning equipment applied to the roller brush in Chinese patent CN216535183U, wherein the saw tooth group includes a plurality of saw teeth and there is a gap B between adjacent saw teeth. After the dirt is scraped off by the saw tooth group of the scraper body, it can be sucked into the sewage tank of the cleaning equipment (floor scrubber) from the gap B with the suction force of the cleaning equipment (floor scrubber). Preferably, the saw teeth can be evenly arranged on the scraping part and the top of each saw tooth is configured as an arc structure, which can avoid the appearance of sharp tips on the saw teeth, so that when the saw tooth group scrapes dirt on the roller brush, its tooth top will not cause damage to the roller brush, thereby extending the service life of the roller brush. The utility model arranges the scraping part of the scraping strip between the dirt suction port and the roller brush, so that the hair or dirt on the roller brush brushed by the scraping part can be directly sucked into the sewage tank through the dirt suction port, thereby preventing the dirt from accumulating on the roller brush, solving the problem that the hair or dirt cannot be effectively collected, and achieving the effect of preventing the accumulation and entanglement of hair on the roller brush. However, the above-mentioned sawtooth structure has been verified in actual application to have a poor actual effect on preventing the accumulation and entanglement of hair on the roller brush.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Please refer to the attached Figure 1-4As shown, a mop assembly provided by an embodiment of the utility model includes a mop body 2 and a roller brush assembly, wherein the mop body 2 is provided with a receiving groove, and the roller brush assembly at least includes a roller brush body 20, wherein the roller brush body 20 is detachably installed in the receiving groove. In actual products, the roller brush assembly usually includes a roller brush body 20 and a roller brush handle provided at one end of the roller brush body 20, wherein the roller brush body 20 is usually also habitually referred to as a roller brush.

[0025] The roller brush body 20 includes a roller core 22 and a roller brush bristle portion 21 arranged on the outside of the roller core 22, and also includes a comb tooth scraper 1. The comb tooth scraper 1 is installed on the floor mop body 2, and its uninstalled end is a comb tooth portion 11 facing the roller brush body 20, and the comb tooth portion 11 is interference fit with the roller brush body 20.

[0026] Specifically, the comb-tooth scraper 1 includes a scraper body 12 and a comb-tooth portion 11 provided on the scraper body 12, the comb-tooth portion 11 includes a plurality of comb-tooth units 110, and the plurality of comb-tooth units 110 are arranged in a line with intervals, the comb-tooth unit 110 is a sheet with a roughly triangular cross-section, and the comb-tooth unit 110 includes a first bevel portion 111 for facing the roller brush after installation, a second bevel portion 112 for facing away from the roller brush, and a third bevel portion 113 for connecting to the scraper body 12, the first bevel portion 111 is provided with a first recess 1111 at an end away from the scraper body 12, the first bevel portion 111 is provided with a second recess 1113 at an end close to the scraper body 12, and the first bevel portion 111 is provided with a first convex portion 1112 for transition connection between the first recess 1111 and the second recess 1113.

[0027] When installed and used, each comb unit 110 of the comb tooth portion 11 extends into the roller brush hair implanting portion 21 of the roller brush. According to the rotation direction of the roller brush during operation, the side where the second bevel portion 112 is located is the front side, and the first bevel portion 111 is the back side. The turned roller brush hair implanting portion 21 first contacts the second bevel portion 112. Due to the inclined characteristics of the second bevel portion 112, the hair covered by the roller brush hair implanting portion 21 can be flicked away and slide along the second bevel portion 112 and finally sucked away (for how the hair is sucked away, please refer to the prior art and will not be repeated here); and the first bevel portion 111 is the first concave portion 1111 that penetrates the roller brush hair implanting portion 21 the deepest, followed by the first convex portion 1112, and then the second concave portion 1113. This concave-convex shape design can reduce the contact with the roller brush hair implanting portion 21 This is because the design of the first recess 1111 makes the first beveled edge 111 of the comb tooth unit 110 at its deepest point almost form an arc segment with the same circumference as the roller brush, especially when the first recess 1111 is set to be concave in an arc shape, the arc segment with the same circumference as the roller brush can be obtained by designing the arc radius of the first recess 1111, which is also the optimal effect. In this way, when the roller brush rotates, the tangent surface of the arc segments (parallel arcs) with the same circumference is 0 during relative rotation, so the tangent force is also 0; the second recess 1113 is to shrink the area of ​​the comb tooth unit 110 as soon as possible so that the comb tooth unit 110 is not too large (the cross section is too wide); the first convex portion 1112 has the effect of smooth transition between the first recess 1111 and the second recess 1113.

[0028] Preferably, the second oblique edge portion 112 is configured as a straight line portion, that is, the side where the second oblique edge portion 112 is located is configured as a straight line, so that the conduction to the hair is smoother.

[0029] The first bevel portion 111 and the second bevel portion 112 are configured as arc edges, which can avoid sharp tips on the bevels, so that when the first bevel portion 111 and the second bevel portion 112 contact the roller brush bristle portion 21, their tips will not cause damage to the roller brush bristle portion 21, thereby extending the service life of the roller brush.

[0030] The scraper strip body 12 includes a mounting portion 121 and a connecting portion 122 . The mounting portion 121 is used for mounting and fixing the comb-tooth scraper strip 1 . The connecting portion 122 is used for connecting with the comb-tooth portion 11 . The mounting portion 121 and the connecting portion 122 are connected at a relatively close side.

[0031] Optionally, the comb-tooth portion 11 is connected to the lower side of the connecting portion 122 , the connecting portion 122 and the mounting portion 121 are connected via a step portion 123 , and the upper side of the connecting portion 122 is lower than the lower side of the mounting portion 121 .

[0032] The lower side of the mounting portion 121 is provided with a plurality of positioning convex strips 13 which can be adapted to the positioning grooves provided at the corresponding positions on the floor brush body, thereby playing the role of pre-alignment and anti-collision when installing the comb-tooth scraper strip 1. The positioning convex strips 13 can also be provided with a plurality of sections and spliced ​​to form a certain shape, such as a rectangle or other shapes.

[0033] The comb-tooth scraper strip 1 adopts an integrated structural design. When manufacturing, if a metal comb-tooth scraper strip 1 is selected, it can be made by cutting or machining. If a plastic comb-tooth scraper strip 1 is selected, it can be made by injection molding.

[0034] In addition, the floor mopping assembly also includes a water squeezing scraper 3, which is overlapped and arranged on the upper side of the comb-tooth scraper 1, and the water squeezing scraper 3 is interference-fitted with the roller brush body 20. The shape of the water squeezing scraper 3 can be set to be adapted to the step shape of the upper side of the comb-tooth scraper 1, so that there are mutual steps between the overlapping contact surfaces between the water squeezing scraper 3 and the comb-tooth scraper 1 to limit the movement of the water squeezing scraper 3 after assembly. It should be noted that in other embodiments, in the case where the water squeezing scraper 3 is not provided, only one wiping portion can be provided, and the wiping portion is provided on the upper side of the connecting portion 122 of the comb-tooth scraper 1 and its inner side abuts against the step portion 123. This is to set the wiping portion and the comb-tooth scraper 1 as an integrated structure, which can also play the role of the water squeezing scraper 3.

[0035] To sum up, in the mopping assembly of the utility model, when the comb tooth scraper 1 is installed and used, each comb tooth unit 110 of the comb tooth portion 11 extends into the roller brush hair-planting portion 21 of the roller brush. According to the rotation direction of the roller brush during operation, the side where the second bevel portion 112 is located is the front side, and the first bevel portion 111 is the back side. The second bevel portion 112 is used to pick up the hair on the roller brush hair-planting portion 21 and smoothly transfer it until it is finally sucked away. The first bevel portion 111 is used to reduce the damage to the roller brush hair-planting portion 21, thereby having a very good effect of removing hair accumulation and hair entanglement on the roller brush.
