[0032] Example 1:

[0033] This embodiment relates to an application head, such as... Figures 1-4As shown, the device includes a housing 1, an applicator 2, and a drive mechanism 3. The housing 1 is detachably connected to an external container 7, and the housing 1 and the external container 7 can be detachably assembled via threads or snaps. The housing 1 has an installation cavity with a liquid outlet channel 10 communicating with the container 7. One end of the housing 1 has an installation port 11 communicating with the installation cavity. The applicator 2 is movably positioned at the installation port 11 and is used to contact the skin. The applicator 2 has a liquid outlet 21 communicating with the liquid outlet channel 10, enabling the applicator 2 to dispense and apply liquid. The drive mechanism 3 is located within the installation cavity and is connected to the applicator 2. The drive mechanism 3 drives the applicator 2 to reciprocate relative to the installation port 11, causing the applicator 2 to pat the skin. By automatically patting the skin with the applicator 2 driven by the drive mechanism 3, the skin can be massaged while applying skincare products, eliminating the need for manual pressing and patting, saving physical effort, and reducing the risk of hand germs contaminating the skin with applied skincare products.

[0034] Optionally, driven by the drive mechanism 3, the applicator 2 can extend and retract along the axial direction of the mounting port 11. Whether in the extended or retracted state, the applicator 2 is partially exposed in the mounting port 11. Alternatively, in the extended state, the applicator 2 is partially exposed in the mounting port 11; in the retracted state, the applicator 2 is completely retracted into the mounting port 11.

[0035] Optionally, the applicator 2 can reciprocate relative to the mounting port 11 along a first direction. The first direction can be parallel to the axial direction of the mounting port 11, or it can intersect the axial direction of the mounting port 11; this is not limited here.

[0036] In some embodiments, such as Figure 1 , Figure 4 As shown, the applicator 2 includes a top wall and a side wall. The side wall is located at the circumferential edge of the top wall. To make the applicator 2 more comfortable when patted on the skin, an arc-shaped transition surface is provided between the side wall and the top wall.

[0037] In some embodiments, such as Figures 3-6 , Figure 9 As shown, to achieve the function of automatically patting the skin with the applicator 2 driven by the drive mechanism 3, the drive mechanism 3 includes a drive component 31 and a transmission assembly 32. The drive component 31 is fixed in the mounting cavity, and the transmission assembly 32 is disposed in the mounting cavity. The transmission assembly 32 is connected to both the drive component 31 and the applicator 2. The drive component 31 drives the transmission component to move, and when the transmission component moves, it causes the applicator 2 to slide axially along the mounting opening 11. The drive component 31 can be any one of a motor, a linear cylinder, or a rotary cylinder. Preferably, the drive component 31 is a motor. The transmission assembly 32 can be a connecting rod structure, a worm gear transmission mechanism, a rack and pinion transmission mechanism, or a crank-slider mechanism, etc.

[0038] Specifically, to enable the transmission component 32 to drive the coating component 2 to perform telescopic movement along the mounting cavity, such as... Figures 3-6 , Figure 9 As shown, the transmission assembly 32 includes an eccentric wheel 321 and a connector 322. The eccentric wheel 321 is disposed on the power output end of the drive member 31, and the drive member 31 is used to drive the eccentric wheel 321 to rotate. One end of the connector 322 is connected to the coating member 2, and the other end is hinged to the eccentric wheel 321. When the eccentric wheel 321 rotates, it drives the connector 322 to reciprocate along the axial direction of the mounting port 11. The connector 322 and the coating member 2 can be connected by means of integral molding, screw connection, bonding, etc. Specifically, the driving component 31 drives the eccentric wheel 321 to rotate. The rotation of the eccentric wheel 321 causes the connecting component 322 to perform circular motion. Since the connecting component 322 is hinged to the eccentric wheel 321, the connecting component 322 can convert the circular motion generated by the eccentric wheel 321 into linear reciprocating motion. In this embodiment, the driving component 31 is a motor or a rotary cylinder, preferably a motor. The motor shaft of the motor has a non-circular structure such as a D-shape, triangle, ellipse, or polygon. The eccentric wheel 321 is provided with a first shaft hole adapted to be inserted into the motor shaft. The motor shaft is inserted into the first shaft hole so that the motor shaft drives the eccentric wheel 321 to rotate synchronously. The rotating shaft at one end of the connecting component 322 is inserted into the second shaft hole of the eccentric wheel 321 to be rotatably connected to the eccentric wheel 321. This rotating shaft is spaced apart from the motor shaft and is not coaxial with the motor shaft. The eccentric wheel 321 can be circular, elliptical, or teardrop-shaped. Optionally, the axis of the rotating shaft is parallel to the axis of the motor shaft; the connector 322 is rod-shaped, and the connector 322 can be in the shape of a line, an L-shape or a Z-shape.

The liquid outlet 21 is located on the light-transmitting area 22. The applicator head also includes a phototherapy component 4. Optionally, the side of the applicator 2 with the liquid outlet 21 is made of a light-transmitting material. In other embodiments, the entire applicator 2 is made of a light-transmitting material, such as jade, silicone, or plastic. The phototherapy component 4 includes a first circuit board 41 and a phototherapy lamp 42 that are electrically connected. The first circuit board 41 is fixed in the cavity and can move synchronously with the applicator 2. The phototherapy lamp 42 is located on the side of the first circuit board 41 facing the light-transmitting area 22. The light of a specific wavelength emitted by the phototherapy lamp 42 can pass through the light-transmitting area 22 and irradiate the skin surface, achieving a dual therapeutic effect of phototherapy and patting to promote the absorption of skincare products. The phototherapy component 4 can emit one or more wavelengths of light selected from 415nm blue light, 630nm red light, 850nm near-infrared light, 560nm green light, 610nm orange light, and 290nm-400nm ultraviolet light. The phototherapy lamp 42 can be one or more selected from LEDs, lasers, fluorescent beads, halogen lamps, electrodeless lamps, and xenon arc lamps, preferably LEDs and / or lasers.

[0040] In some embodiments, to further enhance the functionality of the applicator head, a pair of microcurrent electrodes (not shown in the figure) are symmetrically arranged on both sides of the liquid outlet 21 on the outer wall of the applicator 2. The microcurrent electrodes are electrically connected to the first circuit board 41.

[0044] In some embodiments, such as Figure 2 , Figure 8 , Figure 9 As shown, the housing 1 has a connecting part 12 for detachable connection with the container 7. The connecting part 12 is provided with a liquid inlet 121 communicating with the container 7. The applicator head also includes a first pipe 103 and a second pipe 104 disposed in the mounting cavity. One end of the first pipe 103 is fixed to the connecting part 12 and communicates with the liquid inlet 121.

The first pipe 103 and the second pipe 104 are sealed together. When the connecting shaft part 23 moves, it can drive the second pipe 104 to move in the first pipe 103. The first pipe 103, the second pipe 104 and the first flow channel together form the liquid outlet channel 10. The second pipe 104 is integrally formed with the connecting shaft 23, and is threaded or fixed by hot injection molding. To reduce leakage between the first pipe 103 and the second pipe 104, a sealing element is provided between the second pipe 104 and the first pipe 103. The sealing element is sleeved on the outside of the second pipe 104 and is made of silicone or rubber.
