Description

Technical Field

[0001] The utility model specifically relates to a handheld skin cleaning device. Background Art

[0002] Bathing is a necessary activity in people's daily life. It can remove sweat, dirt and oil and improve the skin's metabolism function. In order to improve the bathing experience, bathing tools such as bath balls and brushes have appeared on the market, with the help of which users can evenly scrub their skin.

[0003] However, since this type of bathing tool requires users to hold it in hand and is less convenient, automated bathing equipment has appeared on the market; for example, the utility model patent with application number 2021231974354 mentions an automatic bath scrubbing device, which achieves automatic bath scrubbing by arranging a driving source in the outer shell to drive the brush head installed on the outer shell to rotate, thereby improving convenience of use.

[0004] When the user uses it, the driving motor starts, and the main shaft drives the brush head to rotate, and the brush head scrubs the user's body. However, the existing bath scrubbing machine has a brush head that is only connected and contacted with the main shaft of the driving motor, and the force of the brush head is only on the main shaft of the driving motor. At the same time, the brush head is driven to rotate by the main shaft. Since the path of movement of the user holding the bath scrubbing machine is not in the same direction as the rotation path, the brush head is subjected to force. At the same time, the user presses the bath scrubbing machine, so that the force acts on the main shaft connected to the brush head, which further affects the rotation of the main shaft of the driving motor, causing the scrubbing disc to rotate slowly or even not rotate, affecting the cleaning effect. In addition, the rotary cleaning method has limitations in use and cannot completely cover the area to be cleaned. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) 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.

[0035] The present application provides a handheld skin cleaning device, which is mainly used for handheld cleaning of the skin surface of the body. The device can rub and clean the skin surface on the moving path by rotating in the same direction or in the same direction along the moving path.

[0036] The handheld operation mode makes it convenient for users to clean various parts of the body, leaving no dead corners.

[0037] The handheld skin cleaning device includes a main body 1 for handheld operation, a cleaning roller 2 arranged at the bottom of the main body, and a driving component and a transmission component arranged inside the main body. The kinetic energy output by the driving component is transmitted to the cleaning roller via the transmission component, and the cleaning roller is caused to rotate relatively, thereby realizing a kneading action on the surface of the skin of the body.

[0038] The main body has a cavity formed inside, which is a sealed space to ensure that water during the cleaning process will not enter the cavity and cause damage to the internal circuit board and drive components. An operating switch is provided on its surface, which is a touch switch, a touch switch, a toggle switch, etc., which is mainly used as a signal input for the user to start the cleaning roller. One side of the main body is set as a cleaning surface, and it has an axis in the length or width direction, and it is set to be handheld and moved along the surface to be cleaned. Preferably, a accommodating groove compatible with the cleaning roller is provided on one side of the cleaning surface, and the cleaning roller is partially embedded in the accommodating groove, and the two ends of the cleaning roller are supported by the side walls of the accommodating groove and can rotate relatively, and either end of the cleaning roller extends into the cavity, and preferably the connection of the cleaning roller is provided with a sealing structure to ensure the waterproof performance of the part.

[0039] At the same time, the main body is formed by a combination of an outer shell and an inner shell. Limit blocks are provided on both sides of the inner shell, and the outer shell is correspondingly provided with limit grooves. The two are plugged in to achieve fixation. At the same time, the bottom of the inner shell cooperates with the outer shell to form a receiving groove 11 for accommodating the cleaning roller. A space for placing the transmission component is formed between one side of the inner shell and the outer shell. The inner shell is also provided with a space for accommodating the drive component, dividing the internal cavity of the main body into functionally independent spaces, so that the various functional parts do not interfere with each other, and at the same time play a role in fixing the various functional parts.

[0040] At least one cleaning roller is arranged on one side of the cleaning surface, and the axis of the cleaning roller is arranged along the relative width or length direction of the main body. The cleaning roller rotates relatively, so that its rotation path is tangent to the travel path of the main body. The cleaning roller can be a roller-like structure with concave or convex objects on the surface, or a brush layer can be directly arranged on its surface, or it can be formed by a plurality of rollers arranged side by side.

[0041] Assuming that the length direction of the main body is X and the width direction is Y, the main body can move relative to the X direction or the Y direction, and the axis of the cleaning roller is arranged along the Y direction or along the X direction.

[0042] The driving component 4 is arranged in the cavity, and drives the cleaning roller to rotate according to the signal of the operating switch 5. The driving component includes a circuit board and a motor, wherein the circuit board is electrically connected to the operating switch, and converts the signal of the operating switch into a driving signal of the motor, thereby causing the motor to rotate.

[0043] The transmission assembly is used to transmit the kinetic energy of the driving assembly to the cleaning roller.

[0044] A hand-held portion 3 is provided on the other side of the main body. The hand-held portion is a handle extending from one side of the main body to any side. The hand-held portion is formed by extending upward from the surface of the main body. The hand-held portion is T-shaped, U-shaped or 7-shaped. Stripes can also be directly set on both sides of the main body to increase friction and facilitate users to hold it directly.

[0045] There are two cleaning rollers, and the two cleaning rollers are matched and hinged on the same plane of the cleaning surface, and the planes formed by the hinged activities of the two cleaning rollers are parallel to each other, and one end of any one or all of the cleaning rollers is provided with a driving member 21 that can cooperate with the transmission assembly.

[0046] At the same time, the bottom surface 12 of the bottom of the main body between the two cleaning rollers can be set as a soft material layer, such as silica gel, and a plurality of convex ribs arranged in an array can also be set there to achieve a further kneading effect.

[0047] Alternatively, a plurality of grooves with an adsorption effect are arranged in an array at the location to absorb and contain liquids, such as bath liquid, lubricating liquid, etc.

[0048] The two cleaning rollers are arranged in parallel so that the two cleaning rollers are evenly stressed and in better contact with the skin surface.

[0049] The two cleaning rollers can be driven by the driving assembly to rotate in the same direction or in opposite directions. The cleaning rollers can be of equal speed or unequal speed, that is, there is a speed difference between the two cleaning rollers, so that the two are subjected to different forces, which enhances the rubbing effect. At the same time, the same direction or opposite direction design can also improve the rubbing effect.

[0050] The surface of the cleaning roller is configured as a concave or convex cleaning surface or the surface of the cleaning roller is provided with a detachable bristle layer. By designing the surface of the cleaning roller, its cleaning effect is improved and its rubbing effect on the skin is improved.

[0051] The concave cleaning surface can adopt a regular or irregular distribution design. The regular design can be an array of grooves or a honeycomb groove array, which can be a hard groove or a flexible groove array. The irregular distribution design can be similar to a sponge-like distribution or a loofah-like structure. And the sponge-like structure or loofah-like structure can also be attached to the surface of the cleaning roller.

[0052] The convex cleaning surface may be in the form of ribs distributed along the circumference of the cleaning roller, or may be in the form of a plurality of convex points distributed along the circumference of the cleaning roller, or in a combination of the above.

[0053] The moving path of the main body is provided with connectors 10 for connecting cable ties in the front and rear directions. The connector is a ring-shaped structure, and a flexible or rigid cable tie can be fixed there. The cable tie can be used to drive the entire device to clean positions that cannot be touched by human hands, such as backup positions.

[0054] The transmission assembly is a gear transmission assembly, a connecting rod transmission assembly or a belt transmission assembly.

[0055] Example 1

[0056] The gear transmission assembly comprises:

[0057] A driving gear 6 is linked to the driving assembly;

[0058] The gear set is meshed with the driving gear and the driving member respectively, and is used for transmitting the kinetic energy of the driving assembly to the cleaning roller.

[0059] The driving gear is connected to the driving shaft of the motor, and the gear set is a plurality of gears meshing with each other. The rotation speed of the cleaning roller can be changed through the transmission of multiple gears. The number of gear sets can be designed according to needs, and the driving member is a driven gear linked with the cleaning roller, so that the three are meshed with each other.

[0060] Example 2

[0061] The connecting rod transmission assembly comprises:

[0062] A driving gear, linked to the driving assembly;

[0063] The connecting rod mechanism 8 is used to transmit the rotation of the driving gear to the cleaning roller.

[0064] The driving gear is connected to the driving shaft of the motor, and is meshed with gears arranged on both sides. The gears are linked with the connecting rod mechanism, and then the driving gear is used to drive the gear to rotate, and the cleaning roller is driven to rotate through the connecting rod mechanism. The connecting rod mechanism can be a three-link mechanism, which realizes the transmission of kinetic energy through fixed connections at both ends and movable connections between the connecting rods.

[0065] Example 3

[0066] The belt drive assembly comprises:

[0067] A driving gear, arranged in linkage with the driving assembly;

[0068] The belt 9 is arranged in linkage with the driving gear and the driving member, and is used for transmitting the rotation of the driving gear to the cleaning roller.

[0069] The driving gear is linked to the driving shaft of the motor. In order to realize that one motor drives two cleaning rollers, two gear sets are set on both sides of the driving gear and mesh with the driving gears respectively, so that the two sets of cleaning rollers are driven by one motor. The belt directly connects the gear set and the cleaning roller, and the belt can also be a chain. The transmission method can be adjusted according to needs. The gear set can also be a single gear. Setting the gear set can adjust the rotation speed of the cleaning roller.

[0070] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
