Abstract
Description
Technical Field
[0001] The invention relates to the technical field of daily washing and gargling, and in particular to a bath scrubber. Background Art
[0002] As we all know, with the metabolism of the human body and the dust in the air, dirt will be produced on the surface of the human skin. In order to remove the dirt, people usually use a towel or a bath towel to pull it back and forth to scrub, which can not only remove the dirt, but also play a massage role, promote blood circulation, and eliminate fatigue. However, this manual scrubbing method is not only unable to scrub the whole body, especially the middle part of the back, which is difficult to complete the scrubbing work by itself, but also requires good physical strength, which is difficult for people with poor physical fitness or inconvenient hands and feet to complete.
[0003] In order to solve the problem that manual scrubbing is not clean enough and consumes a lot of physical energy, people have developed electric bath scrubbers. Electric bath scrubbers drive the detachable rotating cleaning head to rotate through the motor output shaft. The rotating working head with different functions can realize functions such as applying cleaning liquid, rotating scrubbing, and massaging, which effectively solves the problems existing in manual scrubbing.
[0004] However, in actual practice, due to the rapid rotation of the rotating working head, it is not easy to operate when it comes into contact with human skin. That is, its moving direction will be affected by the rotating force of the rotating working head, which requires the user to use greater force to hold it and then control the corresponding moving direction. Secondly, the rotation of the rotating working head will also generate centrifugal force on the liquid on the skin surface, causing splashing, which will also have a great impact on the hygiene of the washroom. Summary of the invention
[0005] In view of the deficiencies in the prior art, the present invention aims to provide a bath scrubber.
[0006] To achieve the above object, the present invention provides the following technical solutions: A bath scrubber, comprising: The bath scrubbing part comprises at least two bath scrubbing rollers arranged in parallel, and the bath scrubbing rollers are arranged perpendicular to the moving axis of the bath scrubbing device, and the rotation direction of any one of the bath scrubbing rollers is arranged opposite to the rotation direction of the other bath scrubbing rollers; The hand-held part is connected to the bath-scrubbing part and has a chamber in which a control module for controlling the rotation of the bath-scrubbing roller is arranged.
[0007] The bath scrubbing part comprises a mounting frame, and a bracket for supporting bath scrubbing rollers is symmetrically arranged on the upper end of the mounting frame. The bath scrubbing rollers are arranged in sequence along the axis direction of the bracket, and the bath scrubbing rollers are linked by a transmission mechanism.
[0008] Both the front and back sides of the bath scrubbing part are arranged as scrubbing surfaces.
[0009] An installation cavity is provided in the bath scrubbing part, and a motor for driving the bath scrubbing roller to rotate is provided in the installation cavity, and the motor is electrically connected to the control module.
[0010] A gear is provided at any end of the bath scrubbing roller, and the transmission structure is a plurality of gear groups meshed with the gears of the bath scrubbing roller.
[0011] Both ends of the bath scrubbing roller are provided with hemispherical scrubbing heads, and the hemispherical scrubbing heads are coaxially arranged with the bath scrubbing roller.
[0012] The bath scrubbing part is coaxially arranged with the hand-held part.
[0013] The front end of the hand-held part is arranged as a U-shaped bayonet, one end of the bath-scrubbing part can be rotatably arranged in the U-shaped bayonet, and a limiting piece for limiting the maximum rotation angle of the bath-scrubbing part is arranged at the matching position between the bath-scrubbing part and the hand-held part.
[0014] One end of the bath scrubbing part extends toward the hand-held part to form a limiting piece, and a portion of the limiting piece enters into the hand-held part.
[0015] Elastic parts for automatically returning the bathing part to the correct position are arranged on the upper and lower sides of the limiting part extending into the inside of the hand-held part.
[0016] The beneficial effects of the present invention are as follows: a plurality of bath scrubbing rollers arranged in parallel can generate a rubbing force on the skin surface by utilizing their own rotation when the bath scrubbing device moves, and one of the bath scrubbing rollers is designed to rotate in the opposite direction, so that the residual torque formed by the accumulation of angular momentum generated by the unidirectional rotation of the other bath scrubbing rollers is offset, thereby making the operation of the bath scrubbing device more stable, less susceptible to the influence of the residual torque generated by the bath scrubbing rollers and causing the moving path to deviate, and at the same time reducing hand fatigue.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0027] The present invention discloses a bath scrubber, which is used for cleaning the skin during bathing. The bath scrubber comprises a bath scrubbing part in contact with the skin and a hand-held part for driving the bath scrubbing part to move along the skin surface. The hand-held part can be a long handle, one end of which is connected to the operating part, or can be directly arranged on any side of the bath scrubbing part, and a hand-held operating part can be arranged on the handle. In this embodiment, in order to better achieve back cleaning, a long handle is used as the hand-held part, such as Figure 7 As shown, the handle is spindle-shaped, and a U-shaped bayonet 120 is formed at one end. The bath scrubbing part is directly arranged at the U-shaped bayonet and connected to the two side walls of the U-shaped bayonet, so that the handle can be used to drive the bath scrubbing part to move along the body surface.
[0028] like Figure 2 and Figure 4 As shown, the bath scrubbing part 200 includes at least two bath scrubbing rollers 300 arranged in parallel, and the bath scrubbing rollers 300 are arranged perpendicular to the moving axis of the bath scrubbing device. Figure 8 As shown by the dotted line in the figure, the rotation direction of any one of the scrubbing rollers 300 is set opposite to the rotation direction of the other scrubbing rollers 300, wherein the rotation speed of the reverse scrubbing roller can be consistent with or different from the rotation speed of the other scrubbing rollers, and in this embodiment, it can be adjusted by the gear transmission ratio of the gear set.
[0029] The reverse rotation of the scrubbing roller is used to offset the residual torque caused by the accumulation of angular momentum generated by the unidirectional rotation of other scrubbing rollers, making the operation of the scrubbing device more stable and less susceptible to the residual torque generated by the scrubbing rollers that may cause the moving path to deviate, while also reducing hand fatigue.
[0030] The opposite direction of the scrubbing rollers is designed to form a bidirectional shear force on the skin surface by using the reverse-rotating scrubbing rollers. This cross-action can more efficiently remove dead skin cells and dirt. At the same time, when the user moves the scrubber, the continuous advancement of the same-direction rollers and the reverse traction of the reverse rollers form a dynamic cleaning grid, which improves the cleaning effect of the scrubber.
[0031] At the same time, the phase difference vibration waves generated by the reverse rotation can interfere with each other, reducing the peak amplitude to a reasonable range, reducing vibration and improving comfort.
[0032] The counter-rotation generates alternating micro-eddies at the contact interface, forming a water film buffer layer and reducing the direct friction intensity.
[0033] The reverse scrubbing roller can create a Venturi effect, increase the water flow rate, and produce periodic pressure pulsations to enhance the flushing effect.
[0034] The reverse rotation forms a "V"-shaped sewage diversion path, which can improve the dirt removal efficiency.
[0035] The scrubbing part 200 includes a mounting frame 210, and a bracket 220 for supporting the scrubbing rollers 300 is symmetrically provided on the upper end of the mounting frame 210. The scrubbing rollers 300 are arranged in sequence along the axial direction of the bracket 220, and the scrubbing rollers 300 are linked by a transmission mechanism. The bracket can be concave to facilitate the storage of the transmission mechanism. In this embodiment, a gear set is used as the transmission mechanism, and the rotation direction of different scrubbing rollers can be adjusted by the number ratio of the gear set.
[0036] like Figure 7 As shown, the handheld part 100 is connected to the scrubbing part 200, which has a chamber, in which a control module for controlling the rotation of the scrubbing roller 300 is arranged. The control module can be a circuit board with a switch and a power supply, which is connected to the motor through the circuit board, and then the motor can be operated. The control circuit board can adopt a conventional control circuit, and it does not belong to the technical problem to be solved by the present application, so it is not described in detail in the present application. At the same time, it is fixedly installed in the chamber. Figure 5 Not shown in the figure.
[0037] In this embodiment, the scrubbing roller is arranged between two brackets, so that both the front and back sides can contact the skin. Therefore, both the front and back sides of the scrubbing part 200 are set as scrubbing surfaces. There is no need to distinguish the front and back sides when using it, and it can be used directly, which is more flexible and convenient.
[0038] The surface of the scrubbing roller is provided with a plurality of protrusions made of flexible material, and the array is arranged equidistantly along its outer surface, so that it can achieve a better kneading effect when it contacts the skin, and by adjusting the diameter of the protrusions, the distribution density can be adjusted. Through the design of different forms of protrusions, the same scrubbing device can achieve different scrubbing effects.
[0039] like Figure 4 As shown, the scrubbing part 200 is provided with an installation cavity 211, and the installation cavity 211 is provided with a motor 500 for driving the scrubbing roller 300 to rotate. The motor 500 is electrically connected to the control module. The motor is directly arranged in the installation cavity of the scrubbing part, which can save the utilization of the internal space of the handle. The connecting line of the motor can be directly extended through the connection position between the scrubbing part and the handle and introduced into the handle, and connected to the control module in the handle, such as the control circuit board.
[0040] like Figure 3 As shown, a gear is provided at either end of the scrubbing roller 300, and the transmission structure is a plurality of gear groups 600 meshing with the gears of the scrubbing roller 300. Through the mutual meshing of the gears, the torque of the motor is transmitted to the scrubbing rollers, and drives them to rotate relative to each other. By adjusting the number of gears, the rotation direction of any of the scrubbing rollers can be changed.
[0041] like Figure 2 As shown, hemispherical rubbing heads 400 are provided at both ends of the scrubbing roller 300, and the hemispherical rubbing heads 400 are coaxially arranged with the scrubbing roller 300. When the scrubbing roller 300 rotates, it can also drive the hemispherical rubbing heads to rotate relatively, thereby realizing rubbing actions in any direction, so that the scrubbing device can be used at any angle, and different usage postures of the scrubbing device can be selected according to different parts of the body.
[0042] The bath scrubbing part 200 is coaxially arranged with the hand-held part 100, and the axis is as follows: Figure 8 As shown by the dotted line in .
[0043] like Figure 7 As shown, the front end of the hand-held part 100 is set as a U-shaped bayonet 120, one end of the scrubbing part 200 can be rotatably set in the U-shaped bayonet 120, and rotating shafts are set on both sides of one end of the scrubbing part, and the rotating shafts can be rotatably connected to the hand-held part. Further, anti-detachment ribs can be set at the ends thereof to ensure that the hand-held part does not fall out, and a limiting member 230 for limiting the maximum rotation angle of the scrubbing part 200 is provided at the matching position between the scrubbing part 200 and the hand-held part 100, and a socket is set on the U-shaped bayonet, and part of the limiting member 230 enters into the interior of the hand-held part through the socket, and the maximum swinging angle of the scrubbing part can be limited by cooperating with the socket.
[0044] One end of the scrubbing part 200 extends toward the hand-held part 100 to form a limit piece 230, and the limit piece 230 partially enters the interior of the hand-held part 100. In this embodiment, the limit piece is a sheet structure, which is directly inserted into the hand-held part. At the same time, by setting the size of the socket 121, it can be made larger than the thickness of the limit piece. Therefore, when the two sides of the scrubbing part are axially connected to the hand-held part, they can swing relative to each other, and the maximum swing angle is limited by the socket.
[0045] like Figure 6 As shown, the upper and lower sides of the limiter 230 extending into the handheld part 100 are provided with elastic parts for the automatic return of the scrubbing part 200, and the elastic parts are springs, that is, a cavity is provided on the upper and lower sides of the limiter inside the handheld part, and the spring is placed in the cavity, and the spring is not shown in the figure, and then when the limiter swings, it will be affected by the self-restoring force of the spring and will recover by itself. At the same time, the existence of the elastic parts will also make the scrubbing part fit the skin more closely, so that the rubbing effect is better. The upper and lower sides of the limiter are respectively formed with protrusions 231, which are used to limit the position of the spring to ensure that the position stability can be guaranteed when the spring is deformed under pressure.
[0046] At the same time, an anti-slip layer can be provided at the holding position of the handheld part to increase friction when holding the device, making it easier to operate and preventing the device from being unable to hold due to the surface being too slippery caused by the cleaning fluid.
[0047] In another embodiment, Figure 8 As shown, it uses a motor as a limiting member, and directly achieves limiting through the cooperation between the motor and the handle, wherein the motor transmits the torque of the motor to the bath roller through various gear matching wheels.
[0048] The embodiments should not be regarded as limiting the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
