Description

Technical Field

[0001] This utility model relates to the technical field of body scrubbing equipment, and more particularly to a roller brush for automatic body scrubbing. Background Technology

[0002] The roller brushes used in existing body scrubbers are consumables that will wear out and need to be replaced after a period of use. Often, only a part of the brush may be damaged, not the entire brush, but the whole brush still needs to be replaced, which is costly. Furthermore, when the roller brush rotates, it usually moves from top to bottom or bottom to top, resulting in a single-angle scrubbing motion and a lack of other angles for thorough cleaning. If the user wants to scrub the body at an angle, they need to tilt their body to achieve a clean result, reducing the user experience. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a roller brush for automatic body scrubbing.

[0004] The objective of this invention is achieved through the following technical solution: A roller brush for automatic body scrubbing includes a roller, a brush head mounting base, and a brush head. The brush head mounting base includes an arc-shaped limiting part, a transverse limiting part, a first trapezoidal protrusion, a second trapezoidal protrusion, and a towel clamping part. The arc-shaped limiting part has arc-shaped inclined surfaces on both sides, and is embedded in the outer periphery of the roller through these inclined surfaces. The transverse limiting part is connected to both ends of the arc-shaped limiting part. The towel clamping part is connected to the side of the transverse limiting part away from the arc-shaped limiting part. The first and second trapezoidal protrusions are both connected to the top of the arc-shaped limiting part. The brush head is connected to the arc-shaped limiting part, the first trapezoidal protrusion, and the second trapezoidal protrusion, and the brush head is equipped with a scrubbing component. This roller brush strengthens the connection between the brush head mounting base and the brush head, allows for individual brush head replacement, reduces maintenance costs, and allows for the replacement of different scrubbing components to suit different bathing needs.

[0005] A better option is that the scrubbing tool includes at least two of the following: an inward-sloping scrubbing rod, a horizontal scrubbing rod, and an outward-sloping scrubbing rod. This scrubbing tool can simultaneously scrub the user's body from multiple directions, allowing the roller brush to clean more thoroughly.

[0006] A better option is that the inner angled scrubbing rod, the horizontal scrubbing rod, or the outer angled scrubbing rod has raised textures. These raised textures can increase the friction of the scrubbing tool, allowing it to clean more thoroughly.

[0007] A better option is that the angle between the cleaning surface of the inner inclined scrubbing rod and the axial direction of the roller ranges from 1 to 89°.

[0008] A better option is that the angle between the cleaning surface of the outwardly inclined scrubbing rod and the axial direction of the roller ranges from 91 to 179°.

[0009] A better option is that the body scrubber is made of an elastic material. The body scrubber has a certain degree of elasticity, allowing it to adapt to different body shapes.

[0010] A better option is a straight-bristled scrubbing brush.

[0011] A better option is that the scrubbing tool is a curved brush.

[0012] A better option includes a bath towel, held in place by two adjacent towel clamping sections. Adding a bath towel to the roller brush increases the contact area between the roller brush and the user's body.

[0013] A better option is that the roller includes a cylindrical portion, a Y-shaped groove, and a transmission locking position. The Y-shaped groove is disposed on the outer periphery of the cylindrical portion, the transmission locking position is disposed on the inner periphery of the cylindrical portion, and the arc-shaped limiting portion is limited to the Y-shaped groove.

[0014] This utility model has the following advantages and beneficial effects compared to the prior art:

[0015] 1. This utility model, through the roller, brush head mounting base and brush head, eliminates the need to replace the entire roller brush when some brush heads are damaged, only the brush head needs to be replaced, thus reducing maintenance costs. The roller brush has a simple structure and is easy to disassemble.

[0016] 2. This utility model, through the scrubbing component, enables the roller brush to simultaneously perform forward, left-angled, and right-angled scrubbing in one rotation, thereby achieving a cleaner scrub or reducing the required number of rotations of the roller brush, thus reducing energy consumption and lowering operating costs.

[0017] 3. This utility model can reduce product costs, increase the contact area between the roller brush and the body by using straight or curved brushes, and make the brush bristles soft, thereby improving the user experience. Attached Figure Description

Detailed Implementation

[0034] The utility model objective of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the implementation of this utility model is not limited to the following embodiments.

[0035] Example 1

[0036] like Figure 1-5 As shown, a roller brush for automatic body scrubbing includes a roller 1, five brush head mounting seats 2, five brush heads 3, and five scrubbing towels 4. The five brush heads 3 are respectively embedded in the five brush head mounting seats 2 to form brush head assemblies. The connection between the brush heads 3 and the brush head mounting seats 2 includes secondary injection molding or high-frequency vibration fixing. The five brush head assemblies are inserted sequentially from left to right onto the outer periphery of the roller 1. Then, the five scrubbing towels 4 are respectively placed over the five brush heads 3, and the two ends of the scrubbing towels 4 are clamped to the two ends of two adjacent brush head mounting seats 2.

[0037] Roller 1 is used for easy assembly and connection with the body scrubber, serving a transmission function. Brush head mounting base 2 is used to install and fix brush head 3, facilitating disassembly and maintenance. Brush head 3 supports the body scrub towel 4, possessing a certain degree of elasticity to allow the body scrub towel 4 to fully contact the user's body. Body scrub towel 4 is used to scrub the user's body and is suitable for use on different shaped parts of the user's body, while also increasing the contact area between the brush head and the user's body.

[0038] like Figure 6 and 7As shown, the roller 1 includes a cylindrical section 101, five Y-shaped slots 102, and six transmission locking positions 103. The five Y-shaped slots 102 are located on the outer periphery of the cylindrical section 101, and are aligned with the axial direction of the cylindrical section 101, evenly distributed around its outer periphery. Each brush head mounting base 2 is engaged with two adjacent Y-shaped slots 102 on both sides. The transmission locking positions 103 are located on the inner periphery of the cylindrical section 101, and the Y-shaped slots 102 limit the movement of the brush head mounting base 2 on both sides.

[0039] The cylindrical part 101 serves as a transmission mechanism, driving the brush head 3 to rotate. The Y-shaped slot 102 is used to hold the brush head mounting base 2; the transmission slot 103 is used to fix the rotating shaft of the scrubbing machine, thereby driving the cylindrical part 101 to rotate.

[0040] like Figure 8-10 As shown, each brush head mounting base 2 includes an arc-shaped limiting part 201, four lateral limiting parts 202, four towel clamping parts 203, a first trapezoidal protrusion 204, a second trapezoidal protrusion 206, and an auxiliary protrusion 205. The structure of the brush head mounting base 2 can be simplified by removing the auxiliary protrusion 205, and the simplified brush head mounting base 2 can be divided into a first mounting base component 21 and a second mounting base component 22, thereby reducing the difficulty of the manufacturing process. Figure 11 As shown. The inner surface of the arc-shaped limiting part 201 fits against the outer periphery of the roller 1, and the axial direction of the arc-shaped limiting part 201 is the same as that of the roller 1. Arc-shaped inclined surfaces 2011 are provided on both sides of the arc-shaped limiting part 201, which can be embedded into the Y-shaped slot 102 of the roller 1. Four transverse limiting parts 202 are respectively connected to both ends of the arc-shaped limiting part 201, that is, each end of the arc-shaped limiting part 201 is connected to two transverse limiting parts 202, and the two transverse limiting parts 202 are arranged opposite to each other. The side of the four transverse limiting parts 202 away from the arc-shaped limiting part 201 is respectively connected to four towel clamping parts 203. The first trapezoidal protrusion 204 and the second trapezoidal protrusion 206 are respectively distributed on the top of the arc-shaped limiting part 201. The auxiliary protrusion 205 is located between the first trapezoidal protrusion 204 and the second trapezoidal protrusion 206. The first trapezoidal protrusion 204, the second trapezoidal protrusion 206, and the auxiliary protrusion 205 are all aligned with the axial direction of the arc-shaped limiting part 201. The first trapezoidal protrusion 204 is embedded in the first trapezoidal fixing part 301 of the brush head 3, the auxiliary protrusion 205 is embedded in the auxiliary fixing part 302 of the brush head 3, and the second trapezoidal protrusion 206 is embedded in the second trapezoidal fixing part 303 of the brush head 3. A buckle 207 is provided at the bottom of each end of the arc-shaped limiting part 201, which can be engaged with the ends of the roller 1 for left and right limiting and fixing.

[0041] The arc-shaped limiting part 201 is used to detachably mount the brush head mounting base 2 onto the roller 1, facilitating the removal of the brush head 3. The lateral limiting part 202 is used to restrict the left and right movement of the brush head 3. The bath towel clamping part 203 is used to clamp both ends of the bath towel 4. The first trapezoidal protrusion 204 and the second trapezoidal protrusion 206 are mainly used to fix the two sides of the brush head 3. The auxiliary protrusion 205 is used to enhance the connection strength between the brush head 3 and the brush head mounting base 2.

[0042] like Figure 12 and 13 As shown, each brush head 3 includes a first trapezoidal fixing part 301, an auxiliary fixing part 302, a second trapezoidal fixing part 303, and three rows of abrasive parts 304. The first trapezoidal fixing part 301, the auxiliary fixing part 302, and the second trapezoidal fixing part 303 are sequentially assembled to form a bath brush base. The first trapezoidal fixing part 301 is sleeved on the first trapezoidal protrusion 204 of the brush head mounting base 2, and the second trapezoidal fixing part 303 is sleeved on the second trapezoidal protrusion 206 of the brush head mounting base 2. The auxiliary fixing part 302 is sleeved on the auxiliary protrusion 205 of the brush head mounting base 2. The three rows of abrasive parts 304 are perpendicularly connected to the first trapezoidal fixing part 301, the auxiliary fixing part 302, and the second trapezoidal fixing part 303, respectively.

[0043] The first trapezoidal fixing part 301 and the second trapezoidal fixing part 303 are both used to strengthen the connection with the brush head mounting base 2. The auxiliary fixing part 302 is used to further enhance the connection between the brush head 3 and the brush head mounting base 2. The scrubbing part 304 is made of elastic material, such as silicone, TPU (thermoplastic polyurethane), or Si-TPV (silicone-based thermoplastic elastomer), and is used for multi-directional scrubbing of the user's body and supporting the scrubbing towel 4.

[0044] like Figure 12 and 13 As shown, the scrubbing tool 304 includes a row of inner oblique scrubbing rods 3041, a row of horizontal scrubbing rods 3042, and a row of outer oblique scrubbing rods 3043. The inner oblique scrubbing rods 3041 are perpendicularly connected to the first trapezoidal fixing part 301, the auxiliary fixing part 302 is perpendicularly connected to the horizontal scrubbing rods 3042, and the outer oblique scrubbing rods 3043 are perpendicularly connected to the second trapezoidal fixing part 303. The cleaning surface of the horizontal scrubbing rods 3042 faces the rotation direction of the roller 1. The angle between the cleaning surface of the inner oblique scrubbing rods 3041 and the cleaning surface of the horizontal scrubbing rods 3042 (i.e., the axial direction of the roller) is an acute angle, ranging from 1 to 89°, preferably 45°. The angle between the cleaning surface of the outer oblique scrubbing rods 3043 and the cleaning surface of the horizontal scrubbing rods 3042 is an obtuse angle, ranging from 91 to 179°, preferably 145°. Raised textures 3404 are provided on the cleaning surfaces of the inner oblique scrubbing rod 3041, the horizontal scrubbing rod 3042, and the outer oblique scrubbing rod 3043. The shape of the raised textures 3404 can be arc-shaped, dot-shaped, or strip-shaped.

[0045] The inward-sloping scrubbing rod 3041 is used to scrub the user's body to the right along an incline during the rotation of the roller brush. The horizontal scrubbing rod 3042 is used to scrub the body horizontally downwards during the rotation of the roller brush. The outward-sloping scrubbing rod 3043 is used to scrub the body to the left along an incline during the rotation of the roller brush. The raised texture 3404 is used to increase the friction of the scrubbing tool 304, making the body cleaner.

[0046] Instructions for using an automatic body scrubber:

[0047] Five brush heads 3 are fixedly connected to the tops of five brush head mounting bases 2 respectively. The first trapezoidal protrusion 204, the second trapezoidal protrusion 206, and the auxiliary protrusion 205 enhance the connection strength of the brush heads 3, and the lateral limiting part 202 limits the brush heads 3 in the left and right directions. The brush head mounting base 2 with the brush heads 3 is pushed into the Y-shaped slot 102 of the roller 1 and locked in place by the friction generated between them. Five bath towels 4 are placed on the five brush heads 3 respectively, and the two ends of the five bath towels 4 are clamped on the ten bath towel clamping parts 203 of the five brush head mounting bases 2 respectively. Then the assembled roller brush is installed on the bath scrubber (which can be purchased on the market). After the bath scrubber is turned on, the roller brush will rotate downward under the drive of the bath scrubber. The roller 1 drives the brush heads 3 and bath towels 4 to rotate through the brush head mounting base 2. The bath towel 4 is rotated downwards to scrub the body. The scrubbing part 304 of the brush head has good elasticity, which allows the bath towel 4 to adapt to different shaped parts of the user's body surface, increasing the contact area. At the same time, the scrubbing part 304 can be used to adjust the softness and hardness of the scrubbing, so as to obtain a good bathing experience and cleaning efficiency.

[0049] Except for the following technical features, the other technical features in this embodiment are the same as those in Embodiment 1, as detailed below:

[0050] 1. For example Figure 2 and 3 As shown, in this embodiment, the five bath towels 4 from Embodiment 1 are removed. With the roller brush rotating downwards, the inner-angled scrubbing rod 3041 tilts to the right, the horizontal scrubbing rod 3042 rolls downwards, and the outer-angled scrubbing rod 3043 tilts to the left. The roller brush in this embodiment can simultaneously scrub the user's body in different directions, resulting in a more thorough cleaning.
