Description

Technical Field

[0001] This utility model relates to the field of facial cleansing equipment technology, and in particular to a facial cleansing device. Background Technology

[0002] Facial cleansing brushes are mainly divided into two categories. One type relies on the vibration effect of a motor to transmit the motor's vibration force to the brush bristles, using the vibration of the bristles to clean pores. The other type relies on the rotational force of a motor to drive the brush head to rotate, using the rotation of the brush head to clean pores. Both types of facial cleansing brushes have drawbacks. When the vibration force is transmitted to the brush head, the vibration force is significantly reduced, resulting in less force acting on the face. Rotary brushes have limited cleaning effect on the face due to insufficient torque, and the cleansing effect cannot meet the user's needs. Excessive rotation speed can damage the skin.

The gear set has a first gear, a first transmission gear, and a second transmission gear; it is understood that the gear set uses multiple transmission gears meshing for transmission, and the overall structure is compact, allowing the output reduction gear to have a larger area; the three-stage gear reduction system can convert the high speed of the micro motor into the ideal speed of the rotating head, ensuring cleaning power while avoiding excessive heat from skin friction.

[0017] 6. The second bracket has an annular boss protruding towards the facial cleansing component; a lip seal is provided between the annular boss and the output rotating shaft, with the outer side of the lip seal contacting the annular boss and the lip edge of the lip seal tightly against the output rotating shaft to achieve a seal. Understandably, the lip seal has the advantages of simple structure, easy installation, and low frictional resistance, ensuring the electrical safety of the product in humid environments.

[0018] 7. The output reduction gear, output rotating shaft, and prism-shaped connector form an integrated structure, which is connected to the drive motor via a gear set. Understandably, using this gear set improves transmission efficiency and transmission ratio accuracy, reduces power consumption, and extends the product's battery life.

[0037] Please see Figure 1 This utility model provides a facial cleansing device 100, including a housing assembly 10, a support assembly 20, a drive assembly 30, and a facial cleansing component 40. The housing assembly 10 serves as the outer shell of the facial cleansing device 100, acting as a container. The housing assembly 10 includes a horizontal section and a vertical section set at an angle, so that the overall structure is T-shaped. In common application scenarios, the vertical section of the housing assembly 10 is usually used as a grip. The support assembly 20 serves as the internal support of the facial cleansing device 100, used to define the position of the drive assembly 30. The drive assembly 30 is used to provide power to drive the facial cleansing component 40 to rotate. The facial cleansing component 40 is used to clean the face.

[0038] Specifically, the support assembly 20, drive assembly 30 and cleansing assembly 40 are located in the horizontal section, and the housing assembly 10 is partially located in the vertical section; the support assembly 20 and drive assembly 30 are located inside the housing assembly 10, and the cleansing assembly 40 is located outside the housing assembly 10.

[0039] Please combine Figure 2 and Figure 3 The bracket assembly 20 includes a first bracket 21 and a second bracket 22, which are disposed on the housing assembly 10. The first bracket 21 has a hollow boss 213 that protrudes toward the second bracket 22. The side of the boss 213 has a boss notch 2131 that connects to the hollow area.

Understandably, this utility model features a main gear set 330 surrounding the boss 213, and the output reduction gear 34 is not on the same plane as the main part of the gear set 330. Increasing the area of ​​the output reduction gear 34 allows for more teeth, resulting in lower speed and higher torque, making it safer to use and achieving a better cleansing effect. The layout surrounding the boss 213 concentrates the gear meshing point in the central area, reducing the risk of eccentric wear. The interval area design provides a buffer space for the transmission component 33, reducing vibration transmission to the body and improving grip stability and comfort. The hollow structure of the boss 213 forms a heat dissipation channel, improving the heat dissipation efficiency of the drive motor 31 and extending the continuous use time.

[0041] Please see Figure 3 The gear set 330 includes a first gear 331, a first transmission gear 332, and a second transmission gear 333.

The prismatic connector can transmit greater torque and is less prone to slippage.

[0045] Please see Figure 3 The output reduction gear 34, the output rotating shaft 35, and the prismatic connector 36 are integrated into one structure. Understandably, the integrated structure reduces wear between the output reduction gear 34 and the output rotating shaft 35.
