Typically, one end of the applicator fits over the container containing the skincare product, while the other end allows the product to flow out of the container. However, current applicators have poor sealing properties. When the container is not in use, even slight squeezing can force the product out of the applicator, resulting in leakage. Utility Model Content

[0003] The main purpose of the utility model is to provide a coating head and a coating device, aiming to prevent the coating head from leaking liquid by arranging a sealing member.

[0004] To achieve the above objectives, the present invention provides a coating head, comprising:

[0005] a main body, comprising a first end, a second end, and a delivery passage extending through the first end and the second end, wherein the first end is adapted to be detachably fixed to a container;

[0020] Container; and

[0021] The coating head has the first end detachably connected to the container.

[0022] According to the technical solution in the embodiment of the utility model, when the cover body is opened, the rolling element is not restricted and can roll freely, which means that there is a rolling gap between the rolling element and the main body. Therefore, when there is a large pressure in the delivery channel, the movable part can be pushed outward to open. The rolling gap provides a space for the movable part to open. For example, when the main body and the container are assembled together, squeezing the container can obtain a large pressure in the delivery channel, thereby achieving liquid discharge. When the pressure in the delivery channel returns to normal, the movable part resumes its elastic deformation and covers the opening of the delivery channel again. When the cover body is closed on the main body, the cover body presses the rolling element against the movable part, restricting the movable part from opening outward again. At this time, even if the container is squeezed, the movable part cannot be pushed outward, thereby avoiding leakage, making it convenient for users to carry the coating device (the coating head and the container are assembled together) with them.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] It should be noted that, in the description of the present invention, if the terms "first", "second", etc. appear, "first" and "second" are only used to facilitate the description of different components or names, and cannot be understood as indicating or implying a sequential relationship, relative importance, or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" appears in the full text, its meaning is to include three parallel solutions. Taking "A and / or B as an example", it includes solution A, or solution B, or solutions that meet both A and B.

[0043] Please refer to Figure 1 and Figure 2 The present invention provides an applicator head 100. One end of the applicator head 100 can be connected to a container (not shown) containing a skin care product such as eye cream, face cream, lotion, or essence. The other end of the applicator head 100 allows the skin care product in the container to flow out, allowing the skin care product to be applied to the user's skin. In addition, the applicator head 100 can also have functional components. The functional components can specifically include any one or a combination of components such as a roller 30, a phototherapy lamp 19, a vibrator, and electrodes, thereby realizing functions such as rolling massage, phototherapy, vibration massage, and microcurrent stimulation.

[0044] Please refer to Figures 1 to 3 、 Figures 8 to 10 In an embodiment of the present invention, the coating head 100 includes a main body 10, a sealing member 20, a rolling member 30, and a cover 40. The main body 10 includes a first end 11, a second end 12, and a delivery channel 13 that passes through the first and second ends 11 and 12. The first end 11 is used to be detachably fixed to a container. The sealing member 20 is disposed at the second end 12 and seals the delivery channel 13 at an opening 131 of the second end 12. The sealing member 20 includes a fixed portion 21 and a movable portion 22. The fixed portion 21 is fixed to the second end 12. The movable portion 22 blocks the opening 131 and can be elastically folded outward from the opening 131 relative to the fixed portion 21. The rolling member 30 is disposed at the second end 12 and is in rolling connection with the main body 10. A portion of the rolling member 30 protrudes outward from the second end 12. The cover 40 covers the second end 12. The cover 40 abuts against the rolling member 30 so that the rolling member 30 presses the movable portion 22 into the delivery channel 13.

[0045] When the lid 40 is opened and the container is squeezed, the skin care products in the container can flow out to the delivery channel 13 in the main body 10 and flow from the first end 11 to the second end 12. When the rolling element 30 rolls relative to the main body 10, the skin care products at the second end 12 can be taken away and applied to the skin, thereby promoting the absorption of the skin care products through rolling massage. When the container is squeezed, the pressure in the container increases and flows outward (along the Figure 5 The movable portion 22 of the sealing member 20 is pushed (in the direction indicated by the arrow X in the figure) to open outward, thereby allowing the skin care product to flow out. When the squeeze on the container is released, the pressure inside the container returns to normal, and the movable portion 22 resumes its elastic deformation and once again covers the opening 131 of the delivery channel 13. When the cover 40 is closed on the main body 10, the cover 40 presses the rolling element 30 against the movable portion 22, preventing the movable portion 22 from opening outward again. At this time, even if the container is squeezed, the movable portion 22 cannot be pushed outward, thereby preventing leakage, making it convenient for users to carry the coating device (the coating head 100 and the container are assembled together) with them.

[0046] Please refer to Figure 4 、 Figures 6 to 8 In some embodiments, the second end 12 is provided with a rolling groove 144, and the opening 131 is provided in the groove wall of the rolling groove 144. A portion of the rolling element 30 is accommodated in the rolling groove 144, and a rolling gap is provided between the rolling element 30 and the groove wall of the rolling groove 144. The rolling gap allows the movable portion 22 to fold outward. When the pressure in the delivery channel 13 is greater than the atmospheric pressure, the greater pressure can push the movable portion 22 outward to deform, and the movable portion 22 arches outward and pushes against the rolling element 30, thereby connecting the delivery channel 13 with the outside world to achieve liquid discharge. Since the rolling groove 144 is provided, it is convenient to hide the sealing element 20 in the rolling groove 144, avoiding exposure of the sealing element 20. Since a portion of the rolling element 30 protrudes outward, it is convenient to contact with the skin to achieve rolling massage. In other embodiments, the second end 12 can also be provided with an axis-shaped member, and the rolling element 30 is rolled and sleeved on the axis-shaped member.

[0047] Furthermore, the groove wall of the rolling groove 144 is further provided with a guide groove 145. The groove wall of the rolling groove 144 may be provided with one or more guide grooves 145, which extend from the opening 131 to the notch of the rolling groove 144. Since the rolling gap is usually small and the outward opening distance of the movable portion 22 is limited, the guide groove 145 is added to make the liquid discharge smoother and avoid blockage. The guide groove 145 can provide a diversion channel for the liquid flowing out of the opening 131, guiding the liquid to flow to the notch of the rolling groove 144.

[0048] Please refer to Figure 5 、 Figures 9 to 11 In some embodiments, the movable portion 22 has a connecting side 221 and a free side 222 opposite to each other. The connecting side 221 is connected to the fixed portion 21, and the free side 222 is closer to the notch of the rolling groove 144 than the connecting side 221. Figure 5 (The X-direction refers to the direction from bottom to top). The connection side 221 of the movable portion 22 is located at the bottom, and the free side 222 is located at the top. The weight of the rolling element 30 is primarily exerted on the bottom. That is, the weight of the rolling element 30 exerted on the connection side 221 is greater than that on the free side 222. When liquid impacts the movable portion 22 from bottom to top, it is more easily dislodged from the free side 222, thereby achieving smooth liquid discharge. In this embodiment, the guide groove 145 is located near the connection side 221.

[0049] In some embodiments, the movable portion 22 includes a pad 223 and a protrusion 224. The pad 223 is connected to the fixed portion 21 and seals the opening 131. The protrusion 224 is located on the side of the pad 223 facing away from the opening 131. The protrusion 224 is used for the rolling element 30 to abut. After the protrusion 224 is provided, it can be ensured that the rolling element 30 can press against the protrusion 224, thereby better preventing the movable portion 22 from opening. In addition, when the rolling element 30 rolls, friction is generated relative to the protrusion 224. The rolling element 30 does not directly contact the pad 223, thereby preventing the pad 223 from being worn and the seal from failing. The shape of the protrusion 224 is not limited, such as a long strip, a cylinder, a sphere, etc., and the number of the protrusions 224 can be one or more.

[0050] Because the seal 20 is an elastic member, such as silicone or rubber, and has a relatively rough surface, if the seal 20 protrudes excessively into the rolling groove 144, the rolling member 30 will have difficulty rolling along the seal 20. To ensure smooth rolling of the rolling member 30, prevent it from getting stuck or becoming difficult to roll, and ensure its proper rolling, the side of the seal 20 facing away from the opening 131 is flush with the wall of the rolling groove 144. In other words, the pad 223 of the entire fixed portion 21 and the movable portion 22 does not protrude into the rolling groove 144. Furthermore, the protrusion 224 protruding into the rolling groove 144 provides support for the rolling member 30, creating a gap between the rolling member 30 and the pad 223, reducing friction and improving the rolling effect of the rolling member 30, while also ensuring the pressing effect of the rolling member 30 against the movable portion 22.

[0051] Please refer to it again Figures 5 to 8 Furthermore, the second end 12 is provided with a receiving groove 146, and the fixing portion 21 is engaged with the receiving groove 146, thereby facilitating the positioning and installation of the fixing portion 21 while reducing the risk of movement of the fixing portion 21. In addition, to prevent the fixing portion 21 from moving, the fixing portion 21 and the main body 10 can also be fixed by bonding. The provision of the receiving groove 146 can also achieve flushness between the fixing portion 21 and the groove wall of the rolling groove 144. Optionally, the receiving groove 146 is opened in the groove wall of the rolling groove 144.

[0052] In some embodiments, the wall of the receiving groove 146 is concave-convex, and the fixing portion 21 is adapted to the receiving groove 146. Specifically, the side surface of the fixing portion 21 is also concave-convex, thereby achieving concave-convex engagement with the wall of the receiving groove 146.

[0053] In order to prevent the sealing member 20 from moving in the direction from the fixed portion 21 to the movable portion 22, the side of the receiving groove 146 that is connected to the opening 131 can be set as a constriction 147, so that a step surface 148 is formed between the receiving groove 146 and the constriction 147, and the edge of the fixed portion 21 can abut against the step surface 148, thereby restricting the fixed portion 21 within the receiving groove 146.

[0054] The rolling element 30 is a sphere, and the rolling groove 144 is basically a spherical groove, and the shape of the rolling groove 144 is larger than half a sphere and smaller than a complete sphere. This not only ensures that a part of the rolling element 30 can protrude outside the rolling groove 144, but also enables the notch of the rolling groove 144 to form a narrow mouth, thereby preventing the rolling element 30 from escaping from the rolling groove 144.

[0055] Please refer to it again Figure 2 In some embodiments, the main body 10 includes a housing 14, a bracket 16, a battery 17, and a circuit board 18. The housing 14 has an installation space 143, which is an axial space. The bracket 16, battery 17, and circuit board 18 are disposed within the installation space 143. One end of the installation space 143 is closed and the other end is open. The closed end is the second end 12. A threaded housing 15 is further disposed at the open end to form the first end 11. The threaded housing 15 has internal threads for threaded connection with a container. Of course, the open end can also be directly provided with internal threads; or the open end can be directly sleeved on the container.

[0056] The housing 14 may be a unitary shell; or Figure 2 As shown, the housing 14 includes multiple shells, such as a first shell 141 and a second shell 142. The second shell 142 can be arranged with both ends connected, and its internal space constitutes an installation space 143. The first shell 141 covers one end of the second shell 142, and the first shell 141 is used to allow the rolling element 30 to roll. The first shell 141 and the second shell 142 can be fixed by bonding, or the first shell 141 and the second shell 142 can be fastened together by snap fastening and a sealing ring is provided between them for sealing.

[0057] The bracket 16 is fixed to the inner wall of the housing 14, and the battery 17 and the circuit board 18 are installed on the bracket 16. In addition, a vibrator 181 can be provided on the circuit board 18. When the vibrator 181 is powered on, it can generate vibrations for vibration massage. The vibrator 181 is a vibration motor. The bracket 16 is also provided with a phototherapy lamp 19. The phototherapy lamp 19 is arranged near the second end 12. The second end 12 is a light-transmitting member. The light emitted by the phototherapy lamp 19 is emitted from the second end 12 for phototherapy. Optionally, the first shell 141 is a light-transmitting member, and the phototherapy lamp 19 can emit any one of red light, blue light, purple light, infrared light, etc.

[0058] The conveying channel 13 can be divided into two sections: one section is formed by the bracket 16, and the other section is formed by the first shell 141. The two sections are connected to form the conveying channel 13. Therefore, in addition to having a plate-like structure to cover the second shell 142, the first shell 141 also has a tubular structure on the inner surface of the plate-like structure to form a portion of the conveying channel 13. Alternatively, the conveying channel 13 can be formed solely by the bracket 16.

[0059] In some embodiments, the housing 14, i.e., the first shell 141, has a second end 12, a portion of which is recessed inward to form a rolling groove 144. The second end 12 is provided with a plurality of rolling grooves 144, each of which contains a rolling element 30. The opening 131 is located in the wall of one of the rolling grooves 144. Optionally, the first shell 141 is a plastic part, and the rolling grooves 144 are formed by integral injection molding. The inner wall of the first shell 141 protrudes inwardly corresponding to the rolling grooves 144.

[0060] The end face of the first shell 141 is tilted, and a plurality of rolling grooves 144 are spaced apart in sequence from top to bottom along the tilted end face, so that each rolling element 30 is also tilted relative to the horizontal plane. When the user holds the applicator head 100, the tilted rolling elements 30 are more in line with the direction of the human facial skin, and the applicator head 100 can basically be held at a comfortable angle, so the arrangement of the rolling elements 30 is more ergonomically designed.

[0061] In some embodiments, the conveying channel 13 passes through an upper rolling groove 144. When two rolling grooves 144 are provided, the conveying channel 13 is provided close to the middle of the two rolling grooves 144.

[0062] The rolling element 30 is a ball, such as a steel ball. The cover 40 abuts the rolling element 30 through its inner sidewall. Alternatively, the inner sidewall of the cover 40 is provided with a protrusion 41, which abuts the rolling element 30. Optionally, the protrusion 41 is an annular protrusion, so that no matter which direction the cover 40 is closed onto the main body 10, the protrusion 41 can be guaranteed to abut the rolling element 30.

[0063] The embodiment of the present invention further provides a coating device, which includes a container and a coating head 100. The specific structure of the coating head 100 can be found in the above embodiment and will not be described again here.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
