[0038] In the following description, suffixes such as "module", "component", "assembly" or "unit" are used only to facilitate the description of the present invention and have no specific meaning. Therefore, they can be used interchangeably.

[0039] The present invention will be further described in detail below through specific implementations in conjunction with the accompanying drawings.

[0040] like Figure 1 、 Figure 2 and Figure 4 As shown, the present application provides a coating head structure, including a coating head body 9 and a ball 1. The coating head body 9 is provided with a first mounting portion 91 and a second mounting portion 92. The ball 1 is mounted on the first mounting portion 91 in a rolling manner, and the coating liquid is applied to the skin by the rolling of the ball 1. Figure 1 and Figure 3 As shown, there can be one or more balls 1 mounted on the first mounting portion 91. The second mounting portion 92 is used to fix to the liquid storage member (not shown). The coating liquid can specifically be a cosmetic liquid, essential oil or liquid medicine.

[0041] The applicator head body 9 also includes a liquid supply channel 2 and a puncture structure 3. The liquid supply channel 2 can be tubular or otherwise shaped to facilitate liquid circulation. The liquid supply channel 2 has a liquid inlet 21 and a liquid outlet 22. The application liquid enters the liquid supply channel 2 through the liquid inlet 21 and exits through the liquid outlet 22. The liquid outlet 22 extends through the first mounting portion 91, thereby delivering the application liquid to the first mounting portion 91 and the ball 1.

[0042] The focus of the improvement of the coating head structure of the present application is on the puncture structure 3 provided on the second mounting portion 92. One end of the puncture structure 3 is connected to the liquid inlet end 21, and the other end of the puncture structure 3 is a pointed end. The pointed end of the puncture structure 3 can puncture the diaphragm on the liquid outlet of the liquid storage component. In addition, the puncture structure 3 is also formed with a puncture channel 31, one end of the puncture channel 31 passes through the pointed end, and the other end of the puncture channel 31 is connected to the liquid inlet end 21. When the puncture structure 3 punctures the diaphragm on the liquid outlet of the liquid storage component, the coating liquid in the liquid storage component can flow through the puncture channel 31 to the liquid inlet end 21 of the liquid supply channel 2, and then through the liquid outlet end 22 of the liquid supply channel 2 to flow onto the ball 1.

[0043] When using a traditional applicator, it's often necessary to pre-puncture the aluminum film or other diaphragm at the top of the reservoir with an external needle to allow the skincare liquid to flow from the reservoir into the applicator. During this process, the needle must be removed after piercing the aluminum film and the applicator installed. During this time, the liquid inside the reservoir is inevitably exposed to the external environment, allowing air and small particles to easily enter the reservoir, which can not only accelerate the oxidative decomposition of the active ingredients in the product but also introduce contaminants such as bacteria and dust.

[0044] When the applicator head structure of the present application is in use, the second mounting portion 92 of the applicator head structure is fixed to the liquid storage member, and the puncture structure 3 within the second mounting portion 92 will inevitably puncture the septum at the liquid outlet of the liquid storage member, allowing the application liquid in the liquid storage member to flow into the applicator head structure. Because puncturing the septum and installing the applicator head structure are completed in one step, the punctured septum will not be exposed to the outside air in the middle. Therefore, the applicator head structure of the present application can prevent contaminants such as outside air, bacteria, and dust from invading the application liquid in the liquid storage member, thereby better protecting the application liquid in the liquid storage member.

[0045] like Figure 1 and Figure 4 As shown, according to one embodiment of the present invention, the tip of the puncture structure 3 includes multiple puncture slopes 32. Each puncture slope 32 is arranged sequentially around the axial direction of the puncture structure 3. From the liquid inlet end 21 toward the tip, the distance between the puncture slopes 32 gradually decreases. In other words, from the liquid inlet end 21 toward the tip, the puncture slopes 32 gradually converge to form a tip. When the tip punctures the septum at the liquid outlet of the liquid storage component, each puncture slope 32 pushes the ruptured septum outward, facilitating the puncture structure 3 to penetrate the target.

[0046] like Figure 1 、 Figure 2 and Figure 4 As shown in the figure, according to one embodiment of the present invention, the main body of the applicator head includes a housing 4 and a mounting bracket 5. The housing 4 serves as an external protective and support structure, providing a stable housing for the internal components. The mounting bracket 5 is disposed inside the housing 4, and the liquid supply channel 2 is disposed on the mounting bracket 5. The puncture structure 3 and the mounting bracket 5 are integrally injection molded, ensuring a seamless connection between the puncture structure 3 and the mounting bracket 5, thereby enhancing the overall strength and sealing of the structure.

[0047] like Figure 1 、 Figure 2 and Figure 4 As shown, according to one embodiment of the present invention, the second mounting portion 92 is cylindrical, open at one end and closed at the other, and is designed to fit over the liquid outlet of the liquid reservoir. A clearance hole 922 is provided at the closed end 921 of the second mounting portion 92, into which the puncture structure 3 is adapted to be inserted. The inner wall of the second mounting portion 92 is internally threaded to facilitate secure connection between the applicator head structure and the liquid reservoir.

[0048] According to one embodiment of the present invention, the tip is located in the second mounting portion 92, and the distance H between the tip and the open end 923 of the second mounting portion 92 needs to be greater than 0, which not only reduces the risk of accidental puncture due to improper operation, but also ensures that the tip can smoothly penetrate the diaphragm and penetrate deep into the liquid storage component, and guide the smear liquid to flow into the liquid supply channel 2.

[0049] like Figure 1 As shown, according to one embodiment of the present invention, a vibrator 51, a battery 52, a circuit board 53 and a button 54 are further provided on the mounting bracket 5, and the vibrator 51, the battery 52 and the button 54 are all electrically connected to the circuit board 53. The shell 4 also has a clearance hole for the button 54 to pass through, ensuring the smooth operation of the button 54. The battery 52 serves as an energy supply unit to provide a stable operating voltage for the circuit board 53 and the vibrator 51. The user controls the start, stop or adjustment of the vibration mode of the device by pressing the button 54. After receiving the control signal from the circuit board 53, the vibrator 51 generates continuous vibration, and this vibration is transmitted to the shell 4 and the ball 1 through the mounting bracket 5. When the ball 1 comes into contact with the skin under the action of vibration, it can effectively promote the microcirculation of the skin surface and accelerate the penetration and absorption of the coating liquid.

[0050] like Figure 1As shown, according to one embodiment of the present invention, the mounting bracket 5 is provided with one or more combinations of a phototherapy lamp 55, a heating element (not shown) and a vibrator 51. Among them, the phototherapy lamp 55 can emit light of a certain wavelength and irradiate the light onto the skin through the ball roller 1. In combination with the rolling stimulation of the ball roller 1, it can promote the metabolism of skin cells and accelerate the penetration of active ingredients in the smear into the deep layer of the skin, thereby improving the skin care effect. The heating element can expand the skin pores and further promote the skin's absorption of the smear, while bringing a soothing and relaxing feeling and enhancing the comfort of care. Since the phototherapy lamp 55, heating element and vibrator 51 in this embodiment are all prior art, they will not be described in detail here.

[0051] In the traditional roller-type applicator structure, the clearance between the ball and the groove in which it is located can control the outflow of the coating liquid. However, after long-term and frequent use, this clearance can easily become a place for debris (such as skin keratin, cosmetic residue, etc.) or tiny bubbles to accumulate. These debris will gradually accumulate and clog the clearance, resulting in poor outflow of the coating liquid or even complete blockage. Users will feel increased resistance to application during use, which greatly reduces the coating effect, seriously affecting the product's performance and user satisfaction. To solve this problem, Figure 1 and Figure 5 As shown, according to one embodiment of the present invention, the first mounting portion 91 is formed with a spherical groove 6, and the ball 1 is in rolling engagement with the spherical groove 6, so that the ball 1 can roll in the spherical groove 6. The liquid outlet 22 penetrates the groove wall of the spherical groove 6 to deliver the coating liquid into the spherical groove 6. The groove wall of the spherical groove 6 is also provided with a guide groove 61, one end of which is connected to the liquid outlet 22, and the other end of which extends to the notch of the spherical groove 6. Therefore, the outflow of the coating liquid no longer relies solely on the narrow gap between the ball 1 and the notch. The guide groove 61 is equivalent to increasing the circulation channel of the coating liquid and reducing the possibility of liquid blockage.

[0052] like Figure 1 and Figure 5 As shown, according to one embodiment of the present invention, there are multiple guide grooves 61, and each guide groove 61 is arranged at intervals on the groove wall of the spherical groove 6. The presence of multiple guide grooves 61 provides multiple flow paths for the flow of the coating liquid, allowing the coating liquid to flow from the liquid outlet end 22 to the groove opening in a multi-directional and dispersed manner, thereby improving the uniformity of the coating liquid distribution. When a certain part of the groove opening of the spherical groove 6 is at risk of clogging due to long-term use or external factors, due to the presence of other guide grooves 61, the coating liquid can still flow out smoothly through other paths, thereby effectively avoiding the problem of liquid discharge failure.

[0053] like Figure 1 and Figure 5As shown, according to one embodiment of the present invention, the first mounting portion 91 includes a base 8 and a snap ring 7 fixed to each other, the base 8 is fixed to the applicator head body 9, the base 8 and the snap ring 7 together form a spherical groove 6, and the snap ring 7 encloses a notch of the spherical groove 6. It should be noted that the diameter of the notch is smaller than the diameter of the ball 1 to prevent the ball 1 from accidentally falling off from the spherical groove 6 during the application process. In addition, it is necessary to ensure that the liquid outlet 22 passes through the base 8 to provide the application liquid to the spherical groove 6. It should be noted that both the base 8 and the ball 1 can be made of light-transmitting parts, so that the light emitted by the phototherapy lamp 55 can be emitted through the base 8 and the ball 1.

[0054] The smearing device provided in the present application includes a liquid storage part and the smearing head structure in the above-mentioned embodiment. The liquid storage part has an open end, and the smearing head structure is connected to the open end. The open end of the liquid storage part is usually covered with a diaphragm such as an aluminum film to isolate the smearing liquid in the liquid storage part from the external air and dust. The liquid storage part can specifically be a liquid storage bottle, a liquid storage hose, etc. The way in which the smearing head structure is connected to the open end includes but is not limited to threaded connection, plug-in connection, snap-on connection, etc. When the smearing head structure is connected to the open end, it can puncture the diaphragm at the open end and enable the smearing liquid in the liquid storage part to flow into the smearing head structure. Since the smearing device of the present application has the smearing head structure in the above-mentioned embodiment, it also has the advantages of the smearing head structure in the above-mentioned embodiment.

[0055] According to one embodiment of the present invention, the open end of the liquid storage member is provided with an external thread. The inner peripheral wall of the second mounting portion of the applicator head structure is provided with an internal thread, and the liquid storage member and the applicator head structure are connected by threads to achieve a fixed connection between the applicator head structure and the liquid storage member.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
