[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0030] This utility model discloses a body scrubber for skin cleaning during bathing. It has a scrubbing part that contacts the skin and a handheld part that moves the scrubbing part along the skin surface. The handheld part can be a long handle, one end of which is connected to the operating part, or it can be directly mounted on any side of the scrubbing part, with a handheld operating component. In this embodiment, a long handle is used as the handheld part for better back cleaning. Figure 7 As shown, the handle is spindle-shaped, with a U-shaped notch 120 at one end. The scrubbing part is directly set at the U-shaped notch and connected to the two side walls of the U-shaped notch, so that the handle can be used to move the scrubbing part along the body surface.
[0031] like Figure 2 and Figure 4 As shown, the scrubbing part 200 includes at least two parallel scrubbing rollers 300, and the scrubbing rollers 300 are arranged perpendicular to the moving axis of the scrubbing device, such as... Figure 8 As shown by the dotted line, the rotation direction of any one bath roller 300 is set opposite to the rotation direction of the other bath roller 300. The rotation speed of the opposite bath roller can be the same as or different from the rotation speed of the other bath rollers. In this embodiment, it can be adjusted by the gear transmission ratio of the gear set.
[0032] The reverse rotation of the rubbing rollers offsets the residual torque formed by the accumulation of angular momentum generated by the single-direction rotation of the other rubbing rollers, making the operation of the rubbing device more stable, less likely to be affected by the residual torque generated by the rubbing rollers, and reducing hand fatigue.
[0033] The reverse rotation of the rubbing rollers forms bidirectional shearing force on the skin surface, which can more efficiently remove dead skin cells and dirt. Meanwhile, when the user moves the rubbing device, the continuous pushing of the same-direction rollers and the reverse pulling of the reverse-direction rollers form a dynamic cleaning grid, improving the cleaning effect of the rubbing device.
[0034] The phase difference vibration waves generated by the reverse rotation can interfere with each other, reducing the amplitude peak value to a reasonable range, reducing vibration, and improving comfort.
[0035] The reverse rotation generates alternating micro-eddy currents at the contact interface, forming a water film buffer layer to reduce direct friction strength.
[0036] The reverse rubbing rollers can form a Venturi effect, increasing water flow speed and generating periodic pressure pulsations to enhance the flushing effect.
[0037] The reverse rotation forms a "V" shaped sewage diversion path, which can improve the efficiency of dirt removal.
[0038] The rubbing part 200 includes a mounting frame 210, the upper end of which is symmetrically provided with a support 220 for supporting the rubbing rollers 300, the rubbing rollers 300 are arranged in sequence along the axis direction of the support 220, and each rubbing roller 300 is connected through a transmission mechanism, the support can be concave, which is convenient for storing the transmission mechanism, in this embodiment, a gear set is used as the transmission mechanism, and the number of gears is matched to adjust the rotation direction of the different rubbing rollers.
[0039] As shown in Figure 7 The hand-held part 100 is connected with the rubbing part 200, has a cavity, and is provided with a control module for controlling the rotation of the rubbing rollers 300, which can be a circuit board with a switch and a power supply, which is connected with the motor through the circuit board, and can operate the motor, wherein the control circuit board can adopt a conventional control circuit, and does not belong to the technical problems to be solved in this application, so it is not described in detail in this application, and it is not shown in Figure 5 .
[0040] In this embodiment, the rubbing rollers are arranged between two supports, so that the front and back surfaces of the rubbing rollers can contact the skin, and therefore the front and back surfaces of the rubbing part 200 are provided with rubbing surfaces, so that the user can use them directly without distinguishing the front and back surfaces, which is more flexible and convenient.
[0041] The surface of the scrubbing roller is provided with a plurality of protrusions made of flexible material, which are equidistantly arranged along the outer surface, so that when the scrubbing roller is in contact with the skin, a better rubbing effect can be achieved, and by adjusting the diameter of the protrusions, the distribution density can be adjusted, and by designing different forms of protrusions, the same scrubbing device can achieve different scrubbing effects.
[0042] As shown in Figure 4 The scrubbing part 200 is provided with a mounting cavity 211, and the mounting cavity 211 is provided with a motor 500 for driving the scrubbing roller 300 to rotate, and the motor 500 is electrically connected with the control module. By directly arranging the motor in the mounting cavity of the scrubbing part, the internal space of the handle can be saved, and the connecting line of the motor can be directly extended and introduced into the handle through the position where the scrubbing part is connected with the handle, and connected with the control module such as the control circuit board in the handle.
[0043] As shown in Figure 3 Any one end of the scrubbing roller 300 is provided with a gear, and the transmission mechanism is a plurality of gear sets 600 meshing with the gears of the scrubbing roller 300. By meshing each gear with each other, the torque of the motor is transmitted to each scrubbing roller, and drives it to rotate relatively, and by adjusting the number of gears, the rotating direction of any one of the scrubbing rollers can be changed.
