[0043] 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.

[0044] The present invention will be further described in detail below through specific implementations in conjunction with the accompanying drawings.

[0045] like Figure 2 and Figure 4 As shown, the present application provides a liquid supply head structure, which includes a liquid supply head body 1. The liquid supply head body 1 is provided with a liquid outlet 11 and a liquid inlet 12. The liquid inlet 12 is used to be fixed to a liquid storage member (not shown). The liquid supply head body 1 includes a liquid blocking member and a liquid supply channel 13 extending through the liquid outlet 11 and the liquid inlet 12. The coating liquid in the liquid storage member flows from the liquid inlet 12 to the liquid outlet 11 through the liquid supply channel 13. The coating liquid can specifically be a cosmetic liquid, essential oil, or liquid medicine.

[0046] To address the problem of liquid leakage from the liquid supply head structure, a liquid barrier is provided on the liquid supply channel 13. This barrier blocks the flow of coating liquid in the liquid supply channel 13. The barrier also has a drain port that can be switched between open and closed to connect or disconnect the liquid supply channel 13 to the outside world.

[0047] In some embodiments, the liquid-blocking member is a resilient seal. It should be noted that the liquid-blocking member does not permanently block the liquid supply channel 13, but rather has a drain port. When the coating liquid within the liquid reservoir is squeezed and flows from the liquid inlet end 12 to the liquid outlet end 11, the drain port is stretched open by the pressure of the coating liquid, allowing the coating liquid to flow through. When the compression of the liquid reservoir ceases, the coating liquid loses pressure, and the drain port closes, preventing the coating liquid from continuing to flow toward the liquid outlet end 11.

[0048] In other embodiments, the liquid-blocking member is an electric valve capable of automatically opening and closing the liquid discharge port.

[0049] In addition, in other embodiments, the liquid-blocking member may also be a manual valve, which is manually opened and closed for the liquid discharge port.

[0050] When using a conventional coating head, since the liquid supply channel 13 does not have a liquid barrier, the coating liquid easily leaks through the gap between the ball and the base, causing unnecessary waste and pollution. The coating head structure of the present application prevents the coating liquid from leaking by providing a liquid barrier on the liquid supply channel 13.

[0051] According to one embodiment of the present invention, the liquid barrier is flexible and elastic, so that it deforms under the pressure of the coating liquid, opening a drainage port to allow the coating liquid to flow; and when the pressure of the coating liquid is removed, it recovers its deformation, closing the drainage port to prevent leakage of the coating liquid. The drainage port on the liquid barrier is specifically a slit provided in the liquid barrier.

[0052] like Figure 2 and Figure 3 As shown, according to one embodiment of the present invention, the liquid supply channel 13 has a liquid outlet 131 located at the liquid outlet end 11. The liquid blocking member includes a first liquid blocking member 2 arranged at the liquid outlet 131, and the liquid discharge port of the first liquid blocking member 2 is the first liquid discharge port 21. The liquid supply head structure also includes a first ball 3, which is rollingly installed on the liquid outlet end 11. The first ball 3 is arranged facing the first liquid blocking member 2, and when the first ball 3 is pressed against the first liquid blocking member 2, the first ball 3 can block the coating liquid from flowing out of the first liquid discharge port 21, so that the first liquid discharge port 21 is closed. Under the blocking action of the first ball 3, the anti-leakage ability of the liquid supply head structure of the present application is further improved.

[0053] like Figure 2 and Figure 5 As shown, according to one embodiment of the present invention, the first liquid-blocking member 2 includes a mounting portion 22 and a first blocking portion 23. The mounting portion 22 is fixed to the liquid supply head body 1 and has a connecting channel 24. The connecting channel 24 is connected to the liquid supply channel 13, and the coating liquid flows to the connecting channel 24 through the liquid supply channel 13. The first blocking portion 23 covers the connecting channel 24. The first blocking portion 23 has a first liquid discharge port 21, and the opening and closing of the first liquid discharge port 21 is achieved by the elastic deformation of the first blocking portion 23. Specifically, the first blocking portion 23 is a flexible flap integrally provided on the mounting portion 22, and the edge of the flexible flap encloses the first liquid discharge port 21. Under the pressure of the coating liquid, the flexible flap is stretched open, thereby opening the first liquid discharge port 21 to allow the coating liquid to flow through. After the pressure of the coating liquid is removed, the flexible flap relies on elasticity to restore its initial posture, thereby closing the first liquid discharge port 21 and blocking the circulation of the coating liquid. When the first ball 3 presses against the first liquid-blocking member 2, it specifically presses against the mounting portion 22 and a portion of the first blocking portion 23, allowing the first ball 3 to block the entire first liquid discharge port 21. Therefore, whether the flexible flap is open or closed, the first ball 3 can block the coating liquid. To ensure a more stable and sealed contact between the first ball 3 and the first blocking portion 23, and to enable the first blocking portion 23 to more quickly return to its initial position due to its elasticity, the first blocking portion 23 is configured to protrude toward the first ball 3 and has a curved structure.

[0054] like Figure 2 and Figure 8As shown, according to one embodiment of the present invention, a first spherical groove 14 is provided on the liquid supply head body 1 for rolling installation of the first ball 3, and the first ball 3 rolls in cooperation with the first spherical groove 14. The groove wall of the first spherical groove 14 is provided with a mounting groove 15, and the groove bottom of the mounting groove 15 is provided with a liquid outlet 131, and the first liquid blocking member 2 is embedded in the mounting groove 15. Specifically, as shown in FIG. Figure 6 As shown, the first liquid-blocking member 2 is further provided with a limiting rib 25, and the mounting groove 15 is provided with a limiting groove corresponding to the limiting rib 25, so that the first liquid-blocking member 2 can play a limiting and guiding role when it is embedded in the mounting groove 15. By increasing the mounting contact area, the first liquid-blocking member 2 can be installed on the mounting groove 15 more stably and not easily fall out.

[0055] like Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the liquid supply head structure further includes a cover 4 disposed on the outside of the liquid outlet end 11. The cover 4 is detachably connected to the liquid supply head body 1, and the specific detachable connection method may be a threaded connection, a snap connection, etc. The cover 4 has a raised portion 41 on the inside. When the cover 4 is disposed on the liquid supply head body 1, the raised portion 41 can press against the first ball 3, causing the first ball 3 to press against the first liquid blocking member 2, thereby sealing the first liquid discharge port 21 and preventing the coating liquid from leaking out of the first liquid discharge port 21.

[0056] like Figure 3 As shown, according to one embodiment of the present invention, the liquid supply channel 13 includes a liquid inlet section 132 and a liquid outlet section 133 that are interconnected. The liquid inlet section 132 passes through the liquid inlet end 12, and the liquid outlet section 133 passes through the liquid outlet end 11. The liquid blocking member also includes a second liquid blocking member 5 arranged between the liquid inlet section 132 and the liquid outlet section 133, and the liquid discharge port of the second liquid blocking member 5 is a second liquid discharge port 51. The second liquid blocking member 5 can block the flow of the coating liquid between the liquid inlet section 132 and the liquid outlet section 133. When the second liquid discharge port 51 is opened, the coating liquid can flow from the liquid inlet section 132 to the liquid outlet section 133; when the second liquid discharge port 51 is closed, it can not only play a double leak-proof function together with the first liquid blocking member 2, but also prevent the coating liquid in the liquid outlet section 133 from flowing back into the liquid inlet section 132 and the liquid storage member to contaminate the coating liquid in the liquid storage member.

[0057] like Figure 2 and Figure 7As shown, according to one embodiment of the present invention, the second liquid blocking member 5 includes a second blocking portion 52 located within the liquid supply channel 13, and a second liquid discharge port 51 is provided on the second blocking portion 52. Specifically, the second blocking portion 52 can also be a flexible flap, the edges of which enclose the second liquid discharge port 51. Under the pressure of the coating liquid, the flexible flap is stretched open, thereby opening the second liquid discharge port 51, allowing the coating liquid to flow from the liquid inlet section 132 to the liquid outlet section 133. After the pressure of the coating liquid is removed, the flexible flap returns to its original position due to its elasticity, thereby closing the second liquid discharge port 51, blocking the flow of the coating liquid and preventing the coating liquid in the liquid outlet section 133 from flowing back. The second blocking portion 52 is concave, with the direction of the concave pointing from the liquid outlet section 133 to the liquid inlet section 132. The second blocking portion 52 is arranged along this concave direction, which enables the coating liquid to return to its original position as quickly as possible after the pressure is removed, thereby promptly closing the second liquid discharge port 51.

[0058] like Figure 2 and Figure 3 As shown, according to one embodiment of the present invention, the liquid supply head body 1 includes a shell 16 and a mounting bracket 17 . The mounting bracket 17 is arranged on the inner side of the shell 16 . The shell 16 is provided with a liquid outlet section 133 , and the mounting bracket 17 is provided with a liquid inlet section 132 .

[0059] like Figure 7 As shown, the second liquid blocking member 5 includes an integral cylindrical portion 53 and a second blocking portion 52. The cylindrical portion 53 is provided with both ends extending therethrough. The second blocking portion 52 is located within the cylindrical portion 53 and separates the two ends of the cylindrical portion 53. The second blocking portion 52 is provided with a second liquid discharge port 51. When the second blocking portion 52 is a flexible flap, the flexible flap is integrally formed with the cylindrical portion 53, and the edge of the flexible flap encloses the second liquid discharge port 51.

[0060] A portion of the outer shell 16 forming the liquid outlet section 133 is inserted into one end of the cylindrical portion 53, and a portion of the mounting bracket 17 forming the liquid inlet section 132 is inserted into the other end of the cylindrical portion 53. The liquid outlet section 133 and the liquid inlet section 132 are connected through the cylindrical portion 53, and the connection and disconnection of the liquid outlet section 133 and the liquid inlet section 132 are controlled by the second blocking portion 52.

[0061] like Figure 8 As shown, according to one embodiment of the present invention, the liquid supply head body 1 further includes a ball seat 18 mounted on the liquid outlet end 11. The ball seat 18 is fixed to the housing 16, and the first spherical groove 14 is provided on the ball seat 18. It can be understood that the liquid outlet 131, the mounting groove 15, and the first liquid blocking member 2 are also provided on the ball seat 18.

[0062] like Figure 8As shown, according to one embodiment of the present invention, a second spherical groove 19 is further provided on the ball seat 18, and a second ball 6 is rollingly installed in the second spherical groove 19. In order to reduce the risk of leakage, the liquid outlet 131 is no longer provided in the second spherical groove 19, and the second ball 6 only plays the role of rolling the skin, and does not play the role of applying liquid. In order to ensure that the cover 4 can simultaneously cover the liquid outlet end 11 with double balls, the first ball 3 and the second ball 6 are staggered in the axial and radial directions of the liquid supply head body 1. Specifically, the first ball 3 is located obliquely below the second ball 6. Such an arrangement can shorten the length of the liquid supply channel 13 and reduce the waste of the coating liquid. At the same time, the first ball 3 located at a low position is also more conducive to liquid discharge.

[0063] According to one embodiment of the present invention, the mounting bracket 17 may also be equipped with one or more of a vibrator (not shown), a phototherapy lamp 7, and a heating element (not shown) to promote microcirculation on the skin's surface, accelerate the penetration and absorption of the application liquid, and enhance the skin care effect. Since the vibrator, phototherapy lamp 7, and heating element in this embodiment are all prior art, they will not be described in detail here.

[0064] like Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, when a phototherapy lamp 7 is provided on the mounting bracket 17, the phototherapy lamp 7 is specifically installed on the mounting bevel 171 of the mounting bracket 17. The inclination angle of the mounting bevel 171 corresponds to the arrangement angle of the first ball 3 and the second ball 6. The correspondence here means that the mounting bevel 171 is basically parallel to the line connecting the centers of the first ball 3 and the second ball 6. In addition, the ball seat 18 needs to be a ball seat 18 made of a light-transmitting material to ensure the transmission of light; the specific position of the phototherapy lamp 7 is also set between the first ball 3 and the second ball 6 to prevent the first ball 3 and the second ball 6 from blocking the light of the phototherapy lamp 7.

[0065] The present application also provides a liquid supply device, comprising a liquid storage component (not shown) and the liquid supply head structure of the above-mentioned embodiment. The liquid storage component has an open end, and the liquid supply head structure is connected to the open end. The liquid storage component can specifically be a liquid storage bottle, a liquid storage hose, etc. The liquid supply head structure can be connected to the open end in ways including, but not limited to, threaded connection, plug-in connection, snap-on connection, and the like. Since the liquid supply device of the present application has the liquid supply head structure of the above-mentioned embodiment, it also has the advantages of the liquid supply head structure of the above-mentioned embodiment.

[0066] 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 liquid inlet end 12 of the liquid supply head structure is provided with an internal thread, and the liquid storage member and the liquid supply head structure are connected by threads to achieve the connection and fixation of the liquid supply head structure and the liquid storage member.

[0067] 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.
