Description

Technical Field

[0001] This utility model relates to the technical field of bathing equipment, and in particular to an automatic body scrubbing device. Background Technology

[0002] Currently, the large obese population, people with physical limitations, the elderly, those who have consumed alcohol, those who are ill, or even healthy individuals experiencing fatigue face various problems and even serious safety incidents when bathing. Even during normal bathing, areas like the back are difficult to clean effectively. Current rollers, when rotating downwards, have a single brush head that doesn't thoroughly clean the body. Furthermore, roller brushes are consumables; if they are partially damaged, the entire roller needs to be replaced, increasing maintenance costs. For the elderly, obese individuals, and those with limited mobility, washing the entire body (involving bending, twisting, and arm flexion) is quite strenuous. A tool is needed that allows for full-body washing while standing. Utility Model Content

Detailed Implementation

[0035] 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.

[0036] Example 1

[0037] like Figure 1 As shown, an automatic scrubbing device includes a longitudinal adjustment mechanism 1, an angle adjustment mechanism 2, a horizontal rotation mechanism 3, a roller brush mechanism 4, and a controller 112. The roller brush mechanism 4 is mounted on the horizontal rotation mechanism 3, and the horizontal rotation mechanism 3 is mounted on the longitudinal adjustment mechanism 1 via the angle adjustment mechanism 2. The controller 112 is mounted at the lower end of the longitudinal adjustment mechanism 1 and is connected to both the horizontal rotation mechanism 3 and the longitudinal adjustment mechanism 1.

[0038] The vertical adjustment mechanism 1 is used to adjust the height of the roller brush mechanism 4 vertically, suitable for users of different heights or for use on different parts of the user's body. The angle adjustment mechanism 2 can adapt to the human body curve and has a large-angle swing function. When the vertical adjustment mechanism 1 moves downward, the user's body approaches the roller brush mechanism 4, and the roller brush mechanism 4 is subjected to pressure. The angle adjustment mechanism 2 has elasticity and changes the angle position of the roller brush mechanism 4, so that the roller brush mechanism 4 can automatically conform to the surface of the human body. The horizontal rotation mechanism 3 provides power for the rotation of the roller brush mechanism 4. The roller brush mechanism 4 is used to wash different shaped parts of the human body. The controller 112 is a PCB circuit board used to control the actions of the vertical adjustment mechanism 1 and the horizontal rotation mechanism 3 to realize the linkage between the two.

[0039] like Figure 3-7As shown, the longitudinal adjustment mechanism 1 includes a drive structure 11, a longitudinal moving structure 12, and a driven structure 13. The drive structure 11 includes a drive bracket 110, a drive fixed base 111, a longitudinal drive motor 114, a drive gear 116, a drive shaft 117, a fan 113, an electromagnetic lock 115, an interference shaft 119, and a drive synchronous pulley 118. The longitudinal moving structure 12 includes a mounting bracket 121, a first synchronous belt 122, a slider base 123, a roller 125, a track 127, and a drag chain 126. The driven structure 13 includes a driven shaft 131, a driven synchronous pulley 132, and a driven fixed base 133. The driven fixed base 133 is mounted on the upper end of the track 127 and has symmetrical adjustment holes. The driven shaft 131 is adjustable up and down and mounted on the adjustment holes of the driven fixed base 133. The driven synchronous pulley 132 is rotatably mounted on the driven shaft 131 relative to the driven shaft 131. The two ends of the first synchronous belt 122 are connected to the two ends of the slider base 123 via clamping plates 124 to form a transmission ring. The upper end of the transmission ring (i.e., the first synchronous belt 122) is connected to the driven synchronous pulley 132. The slider base 123 is slidably mounted in the track 127 via rollers 125. The mounting bracket 121 is mounted on the front side of the slider base 123 via the mounting base 122. The slider base 123 is connected to one end of the drag chain 126, and the other end of the drag chain 126 is connected to the drive fixed base 111, which is mounted at the lower end of the track 127. The drive bracket 110 is mounted on the drive fixed base 111, and the drive shaft 117 is rotatably mounted on the drive bracket 110. One end of the drive shaft 117 protrudes outward through the drive bracket 110, and the protruding end of the drive shaft 117 is connected to the interference shaft 119. The drive gear 116 and the drive synchronous pulley 118 are mounted on the drive shaft 117 and located inside the drive bracket 110. A longitudinal drive motor 114 is mounted on a drive base 111. A pinion gear is mounted on the shaft of the longitudinal drive motor 114, meshing with a drive gear. A drive synchronizing pulley 118 is connected to the lower end of a transmission ring (i.e., the first synchronous belt 122). An electromagnetic lock 115 and a controller 112 are both mounted on the drive base 111. The electromagnetic lock 115 has a telescopic rod; when the telescopic rod extends, it blocks the rotation of the interference shaft 119, thereby limiting the rotation of the drive shaft 117. A fan 113 is mounted to the side of the controller 112, which is connected to the longitudinal drive motor 114, the electromagnetic lock 115, and the fan 113.

[0040] The drive structure 11 provides power for and locks the vertical movement of the longitudinal moving structure 12. The drive bracket 110 is used to mount the drive shaft 117 and the drive gear 116. The drive mounting base 111 is used to mount the controller 112, the longitudinal drive motor 114, the fan 113, and the electromagnetic lock 115. The longitudinal drive motor 114 provides power for the vertical movement of the horizontal rotating mechanism 3. The drive gear 116 is used to adjust the speed of the longitudinal drive motor 114 and achieve transmission. The drive shaft 117 drives the rotation of the drive synchronous pulley 118 and the interference shaft 119. The fan 113 provides cooling for the controller 112. The electromagnetic lock 115 restricts the rotation of the drive shaft 117, preventing the horizontal rotating mechanism 3 and the brush mechanism 4 from falling. The interference shaft 119 is limited by the electromagnetic lock 115. The drive synchronous pulley 118 drives the first synchronous belt 122. The longitudinal moving structure 12 guides the vertical movement of the horizontal rotating mechanism 3. The mounting bracket 121 is used to mount and fix the horizontal rotating mechanism 3. The first synchronous belt 122 serves as a transmission mechanism, transmitting power from the driving synchronous pulley 118 to the slider base 123, allowing the slider base 123 to slide up and down relative to the track 127. The slider base 123 can rotate relative to the track 127, enabling the horizontal rotation mechanism 3 to move up and down. The roller 125 can be replaced by a friction plate to reduce the friction between the slider base 123 and the track 127. The track 127 guides the slider base 123. The cable chain 126 protects the wires connecting the controller 112 and the horizontal rotation motor 301 of the horizontal rotation mechanism 3, and prevents the wires from affecting the sliding of the slider base 123 on the track 127. The driven structure 13 is used to adjust the tension of the first synchronous belt 122 and to fix the first synchronous belt 122. The driven shaft 131 and the driven fixed base 133 adjust the tension of the first synchronous belt 122. The driven synchronous pulley 132 is used to fix the upper end of the first synchronous belt 122.

[0041] like Figure 8As shown, the horizontal rotation mechanism includes a horizontal rotation motor 301, a first shaft base 302, a first drive shaft 303, a second shaft base 304, a first drive gear 305, a third shaft base 306, a transmission chain 307, a transverse support 308, a rotating shaft base 309, a second drive gear 310, and a fourth shaft base 311. The middle part of the transverse support 308 is connected to the mounting bracket 121. The rotating shaft base 309 is mounted on the transverse support 308. The horizontal rotation motor 301, the first shaft base 304, the second shaft base 306, and the third shaft base are sequentially arranged on the rotating shaft base 309. The first drive shaft 303 is rotatably mounted on the first shaft base 304, the second shaft base 306, and the third shaft base. The horizontal rotation motor 301 is connected to one end of the first drive shaft 303 via a coupling, and the horizontal rotation motor 301 is connected to the controller 112. The first drive gear 305 is mounted on the other end of the first drive shaft 303. The first transmission gear 305 is connected to the second transmission gear 310 via a transmission chain 307. The two ends of the central shaft 44 of the roller brush mechanism 4 are rotatably mounted on the two ends of the transverse support 308 via two fourth shaft bases 311, and the second transmission gear 310 is connected to the right end of the central shaft 44.

[0042] A horizontal rotary motor 301 provides power for the rotation of the brush mechanism 4. A first drive shaft 302 transmits power from the horizontal rotary motor 301 to a first drive gear 305. A first shaft base 304, a second shaft base 305, and a third shaft base 306 are all used to mount the first drive shaft 303. The first drive gear 305 transmits power from the first drive shaft 303 to a drive chain 307. The drive chain 307 transfers power from the first drive gear 305 to a second drive gear 310. A transverse bracket 308 secures a rotating shaft base 311 and a fourth shaft base. A rotating shaft base 309 mounts the horizontal rotary motor 301 and the first drive shaft 303.

[0043] like Figure 8-10 As shown, the roller brush mechanism 4 includes a washing drum 43, five brush head mounting seats 42, and five brush heads 41. The five brush heads 41 are respectively embedded into the five brush head mounting seats 42 to form brush head assemblies. The connection between the brush heads 41 and the brush head mounting seats 42 includes secondary injection molding and high-frequency vibration fixing. The five brush head assemblies are inserted sequentially from left to right into the outer periphery of the washing drum 43. Then, five bath towels 4 are respectively placed over the five brush heads 41. The central shaft 44 is used to drive the drum 431 to rotate.

[0044] The scrubbing drum 43 is used for easy assembly and connection with the body scrubbing device, serving a transmission function. The brush head mounting base 42 is used to install and fix the brush head 41, facilitating disassembly and maintenance. The brush head 41 has a certain degree of elasticity, allowing it to make full contact with the user's body.

[0045] like Figure 16 As shown, the washing drum 43 includes a rotating drum 431 and five Y-shaped slots 432. The five Y-shaped slots 432 are located on the outer periphery of the rotating drum 431, and are aligned with the axial direction of the rotating drum 431, evenly distributed around its outer periphery. Each brush head mounting base 42 is engaged with two adjacent Y-shaped slots 432 on both sides. The central shaft is located on the inner periphery of the rotating drum 431, and the Y-shaped slots 432 limit the movement of the brush head mounting base 42 on both sides.

[0046] The rotating drum 431 serves as a transmission mechanism, driving the brush head 41 to rotate. The Y-shaped slot 432 is used to hold the brush head mounting base 42.

[0047] like Figure 13 and 14 As shown, each brush head mounting base 42 includes an arc-shaped limiting part 421, four lateral limiting parts 422, four towel clamping parts 423, a first trapezoidal protrusion 424, a second trapezoidal protrusion 426, and an auxiliary protrusion 425. The inner surface of the arc-shaped limiting part 421 fits against the outer periphery of the washing drum 43, and the axial direction of the arc-shaped limiting part 421 is the same as the axial direction of the washing drum 43. Both sides of the arc-shaped limiting part 421 are provided with arc-shaped inclined surfaces 4211, which can be embedded into the Y-shaped slots 432 of the washing drum 43. The four lateral limiting parts 422 are respectively connected to the two ends of the arc-shaped limiting part 421, that is, each end of the arc-shaped limiting part 421 is connected to two lateral limiting parts 422, and the two lateral limiting parts 422 are arranged opposite to each other. The sides of the four lateral limiting portions 422 away from the arc-shaped limiting portion 421 are respectively connected to the four towel clamping portions 423. The first trapezoidal protrusion 424 and the second trapezoidal protrusion 426 are respectively distributed on the top of the arc-shaped limiting portion 421. The auxiliary protrusion 425 is located between the first trapezoidal protrusion 424 and the second trapezoidal protrusion 426. The first trapezoidal protrusion 424, the second trapezoidal protrusion 426 and the auxiliary protrusion 425 are all aligned with the axial direction of the arc-shaped limiting portion 421. The first trapezoidal protrusion 424 is embedded in the first trapezoidal fixing portion 411 of the brush head 41, the auxiliary protrusion 425 is embedded in the auxiliary fixing portion 412 of the brush head 41, and the second trapezoidal protrusion 426 is embedded in the second trapezoidal fixing portion 413 of the brush head 41. A buckle 427 is provided at the bottom of each end of the arc-shaped limiting portion 421. The buckle 427 can be locked onto the ends of the washing drum 43 for left and right limiting and fixing.

[0048] The arc-shaped limiting part 421 is used to detachably mount the brush head mounting base 42 onto the washing drum 43, facilitating the removal of the brush head 41. The lateral limiting part 422 is used to restrict the left and right movement of the brush head 41. The bath towel clamping part 423 is used to clamp both ends of the bath towel 4. The first trapezoidal protrusion 424 and the second trapezoidal protrusion 426 are mainly used to fix the two sides of the brush head 41. The auxiliary protrusion 425 is used to enhance the connection strength between the brush head 41 and the brush head mounting base 42.

[0049] like Figure 12 As shown, each brush head 41 includes a first trapezoidal fixing part 411, an auxiliary fixing part 412, a second trapezoidal fixing part 413, and three rows of abrasive parts 414. The first trapezoidal fixing part 411, the auxiliary fixing part 412, and the second trapezoidal fixing part 413 are sequentially assembled to form a bath brush base. The first trapezoidal fixing part 411 is sleeved on the first trapezoidal protrusion 424 of the brush head mounting base 42, and the second trapezoidal fixing part 413 is sleeved on the second trapezoidal protrusion 426 of the brush head mounting base 42. The auxiliary fixing part 412 is sleeved on the auxiliary protrusion 425 of the brush head mounting base 42. The three rows of abrasive parts 414 are perpendicularly connected to the first trapezoidal fixing part 411, the auxiliary fixing part 412, and the second trapezoidal fixing part 413, respectively.

[0050] The first trapezoidal fixing part 411 and the second trapezoidal fixing part 413 are both used to strengthen the connection with the brush head mounting base 42. The auxiliary fixing part 412 is used to further enhance the connection between the brush head 41 and the brush head mounting base 42. The scrubbing part 414 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.

[0051] like Figure 11 and 12 As shown, the scrubbing tool 414 includes a row of inner oblique scrubbing rods 4141, a row of horizontal scrubbing rods 4142, and a row of outer oblique scrubbing rods 4143. The inner oblique scrubbing rods 4141 are perpendicularly connected to the first trapezoidal fixing part 411, the auxiliary fixing part 412 is perpendicularly connected to the horizontal scrubbing rods 4142, and the outer oblique scrubbing rods 4143 are perpendicularly connected to the second trapezoidal fixing part 413. The cleaning surface of the horizontal scrubbing rods 4142 faces the rotation direction of the scrubbing drum 43. The angle between the cleaning surface of the inner oblique scrubbing rods 4141 and the cleaning surface of the horizontal scrubbing rods 4142 (i.e., the axial direction of the central axis) is an acute angle, ranging from 1 to 89°, preferably 45°. The angle between the cleaning surface of the outer oblique scrubbing rods 4143 and the cleaning surface of the horizontal scrubbing rods 4142 is an obtuse angle, ranging from 91 to 179°, preferably 145°. Raised textures 4144 are provided on the cleaning surfaces of the inner oblique scrubbing rod 4141, the horizontal scrubbing rod 4142 and the outer oblique scrubbing rod 4143. The shape of the raised textures 4144 can be arc-shaped, dot-shaped or strip-shaped.

[0052] The inward-sloping scrubbing rod 4141 is used to scrub the user's body to the right along an angle while the roller brush rotates. The horizontal scrubbing rod 4142 is used to scrub the body horizontally downwards while the roller brush rotates. The outward-sloping scrubbing rod 4143 is used to scrub the body to the left along an angle while the roller brush rotates. The raised texture 4144 is used to increase the friction of the scrubbing tool 414, making the body cleaner.

[0053] Instructions for using the roller brush mechanism 4: Five brush heads 41 are fixedly connected to the tops of five brush head mounting seats 42 respectively. The first trapezoidal protrusion 424, the second trapezoidal protrusion 426, and the auxiliary protrusion 425 enhance the connection strength of the brush heads 41. The lateral limiting part 422 limits the brush heads 41 in the left and right directions. The brush head mounting seat 42 with the brush heads 41 installed is pushed into the Y-shaped slot 432 of the scrubbing drum 43 and secured. The two are fixed by the friction generated between them. Then, the assembled scrubbing drum 43 is installed on the central shaft 44. After the scrubbing device is turned on, the scrubbing drum 43 will rotate downwards under the drive of the horizontal rotation mechanism 3. The scrubbing drum 43 drives the brush heads 41 to rotate downwards through the brush head mounting seats 42. The scrubbing part 414 of the brush head has good elasticity, allowing it to adapt to different shapes of the user's body surface, increasing the contact area. Simultaneously, the scrubbing part 414 adjusts the softness and hardness of the scrubbing, resulting in a good bathing experience and cleaning efficiency.

[0054] As shown in Figure 18, the angle adjustment mechanism 2 includes a first adjustment plate 201, a connecting shaft 202, a tension spring 203, and a second adjustment plate 204. Both the first adjustment plate 201 and the second adjustment plate 204 have through holes, through which the connecting shaft 202 passes. Both the first adjustment plate 201 and the second adjustment plate 204 can rotate relative to the connecting shaft 202. The tension spring 203 is sleeved on the connecting shaft 202, located between the through holes. Both ends of the tension spring 203 abut against the first adjustment plate 201 and the second adjustment plate 204, respectively. The first adjustment plate 201 is connected to the transverse support 308 of the horizontal rotation mechanism 3, and the second adjustment plate 204 is connected to the mounting bracket 121 of the longitudinal adjustment mechanism 1.

[0055] The first adjusting plate 201 is used to fix the transverse support 308. The connecting shaft 202 is used to fix the tension spring 203 and allow the first adjusting plate 201 and the second adjusting plate 204 to rotate relative to each other. The tension spring 203 uses its own elastic force to open the first adjusting plate 201 and the second adjusting plate 204. The second adjusting plate 204 is used to fix the mounting bracket 121.

[0056] Instructions for using an automatic body scrubbing device: The user turns on the device and adjusts the height of the roller brush mechanism 4 according to their needs. The controller 112 controls the vertical drive motor 114 to rotate, and the roller brush mechanism 4 moves up or down on the vertical adjustment mechanism 1 until it meets the user's needs. The user adjusts the rotation speed of the roller brush mechanism 4 according to their needs, and the controller 112 controls the speed of the horizontal rotation motor 301. The horizontal rotation motor 301 drives the roller brush mechanism 4 to rotate, thereby achieving the scrubbing force of the roller brush mechanism 4. When the user's body approaches the roller brush mechanism 4, the user's body pushes against the roller brush mechanism 4, and the roller brush mechanism 4 receives the pushing force. Due to the pushing force, the angle adjustment mechanism 2 automatically adjusts the position of the roller brush mechanism 4 to conform to the user's body curve, allowing the body scrubbing towel 5 to fit more closely to the user's body, thereby controlling the scrubbing force of the body scrubbing towel 5 in contact with the user's body and achieving a good body scrubbing experience.

[0057] Example 2

[0058] Except for the following technical features, the other technical features in this embodiment are the same as those in Embodiment 1:

[0059] 1. For example Figure 2 As shown, in this embodiment, the angle adjustment mechanism 2 is removed, and the longitudinal adjustment mechanism 1 is directly connected to the horizontal rotation mechanism 3. This reduces the use of the angle adjustment mechanism 2, simplifies the structure, and reduces production costs to meet the needs of different users.

[0060] Example 3

[0061] Except for the following technical features, the other technical features in this embodiment are the same as those in Embodiment 1:

[0062] like Figure 17 As shown, in this embodiment, five bath towels 5 are installed on the roller brush mechanism. Specifically, the bath towels 5 cover the brush head 41, and both ends of the bath towels 5 are clamped to the bath towel clamping part 423 of the brush head mounting base 42. The brush head 41 supports the bath towels 5 and has a certain degree of elasticity, allowing the bath towels 5 to fully contact the user's body. The bath towels 5 are all used to scrub the user's body and are 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.

[0063] The device in this embodiment will fill a market gap. The device has a relatively simple structure, low production cost, and higher bathing efficiency than traditional bathing methods. It will also greatly reduce the time spent on bathing, and is compatible with the user's current bath towel (no need to replace the bath towel). It also achieves water conservation, green environmental protection, economy and carbon neutrality.

[0064] The above-described specific embodiments are preferred embodiments of this utility model and are not intended to limit this utility model. Any other changes or equivalent substitutions made without departing from the technical solution of this utility model are included within the protection scope of this utility model.
