Description

Technical Field

[0001] The utility model relates to the technical field of skin care products, in particular to an applicator head and an application device. Background Art

[0002] An applicator head is an independent component used to connect to the bottle mouth of a cosmetic product, an essential oil product, or certain skin medications. It is internally provided with a liquid outlet pipe for discharging liquid and a contact part for applying the liquid in the bottle to the skin. The liquid outlet pipe is used to transport the liquid in the bottle to the contact part, and the contact part is used to contact the skin to apply the cosmetic liquid to the skin; some applicator heads are also internally provided with a vibrator, which is used to drive the contact part to vibrate, and massage the skin when or after applying the cosmetic liquid to promote the absorption of the cosmetic liquid by the skin.

[0003] Existing applicator heads are usually connected to the bottle mouth of cosmetic products by means of threaded connection. Since there are a wide variety of cosmetic products, essential oil products, or certain skin medications on the market, and the diameters of the bottle mouths are different; therefore, applicator head manufacturers need to separately produce corresponding applicator heads for bottle mouths of different diameters, that is, they need to re-open molds for bottle mouths of different specifications, which leads to an increase in the overall production cost.

[0004] How to reduce the production cost of the applicator head while ensuring that it can adapt to different bottle mouth diameters is a technical problem that current applicator head manufacturers urgently need to solve. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an applicator head, which has a split-designed applicator head body, a threaded module, and a stimulating component. The applicator head is formed by the cooperation of the three. Through the split design method, the threaded module is designed separately. The threaded module can be produced according to different bottle mouth diameters, and finally assembled with the applicator head body and the stimulating component. For different bottle mouth diameters, only different diameter threaded modules need to be selected for assembly to form an applicator head, instead of separately opening molds to manufacture applicator heads for different bottle mouths as in the traditional technology. While ensuring that it can adapt to different bottle mouth diameters, the production cost of the applicator head is reduced.

[0006] The utility model provides an applicator head, comprising:

[0007] An applicator head body, in which a liquid supply channel and an installation cavity are provided. The liquid supply channel has a liquid inlet end and a liquid outlet end.

[0042] The present utility model will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0043] According to an embodiment of the present utility model, as Figures 1 to 6 shown, a coating head includes:

[0044] The applicator head body is provided with a liquid supply channel 901 therein. In this embodiment, the liquid supply channel 901 is a liquid supply pipe 9, and the liquid supply pipe 9 forms the liquid supply channel 901. Of course, the liquid supply channel 901 is not necessarily tubular and can also be of other shapes as long as it can form a liquid flow channel. In this embodiment, the liquid supply channel 901 is taken as an example of the liquid supply pipe 9. As Figure 11 shown, the liquid inlet end 902 of the liquid supply pipe 9 is used to connect with the liquid storage member 24, and the liquid outlet end 903 is used to output the liquid in the liquid storage member 24. An installation cavity 101 is formed inside the applicator head body, and the liquid inlet end 902 of the liquid supply pipe 9 is located at the bottom wall of the installation cavity 101;

[0045] The stimulating member is installed on the applicator head body and is located at the liquid outlet end 903 of the liquid supply pipe 9;

[0046] The thread module 2 is located inside the installation cavity 101 and is sleeved with the applicator head body inside and outside. The inner peripheral wall of the thread module 2 is provided with an internal thread 3, and a communication port is also provided at the position of the thread module 2 corresponding to the liquid inlet end 902 of the liquid supply pipe 9;

[0047] One of the thread module 2 and the cavity wall of the installation cavity 101 is provided with a tongue 5, and the other is provided with a slot 4 for the tongue 5 to insert into.

[0048] As Figure 11 shown, when the applicator head of the present utility model is used, it is connected to the liquid outlet of the liquid storage member 24, and the liquid stored in the liquid storage member 24 can be cosmetic liquid, essential oil or the liquid medicine of certain medicines.

[0049] For existing applicator heads, it is necessary to separately mold according to the diameter of the bottle mouth or the specification of the thread of different cosmetic or essential oil products or certain skin medicine bottles one by one in order to combine with the bottle mouth of the corresponding product. Since there are a wide variety of such products on the market, the diameters of the bottle mouths are different, and the bottle mouth thread designs are also different, which undoubtedly brings great production pressure to the manufacturers of applicator heads.

[0050] Based on years of work experience and understanding of the applicator head, the inventors of the present application found that other parts inside the applicator head, such as the stimulating component and the applicator head body, are universal, and the non-universal part is mainly the threaded part connecting to the bottle mouth of the cosmetic product. Thus, the applicator head of this embodiment is proposed. The applicator head of this embodiment includes an applicator head body, a stimulating component, and a threaded module 2. The three are independent of each other. During production, the three are separately molded, and finally assembled according to the specifications of the bottle mouth of the cosmetic product to be adapted. The advantage of such a design is that the components that originally needed to be integrally molded are divided into three parts. Among them, the applicator head body and the stimulating component have a certain degree of universality. When the cosmetic product to be adapted changes, the already produced applicator head body and stimulating component will not be discarded. Although the threaded module 2 is a dedicated component, in this embodiment, it is independently designed, simplifying the complexity. Only different specifications of the threaded module 2 need to be produced, such as producing three types of threaded modules 2, namely A, B, and C. The differences between the various types of threaded modules 2 are only in the diameter and / or the width of the thread teeth and / or the number of thread teeth of the internal thread 3. By assembling the three types of threaded modules 2 with the applicator head body and the stimulating component respectively, an applicator head that can adapt to three different cosmetic products can be formed.

[0051] In this example, the threaded module 2 is independently designed from the applicator head body and the stimulating component, and assembled according to the cosmetic product to be adapted to form an applicator head, which can reduce the production cost of the applicator head on the premise of adapting to different diameters of the cosmetic bottle mouths.

[0052] In this embodiment, as Figures 3 to 6 shown, an uneven mating structure is formed between the inner side of the applicator head body and the outer side of the threaded module 2. In this embodiment, the threaded module 2 is located in the installation cavity 101 and is sleeved with the applicator head body inside and outside. The inner peripheral wall of the threaded module 2 is provided with an internal thread 3, and a communication port is also provided at the position of the threaded module 2 corresponding to the liquid inlet end 902 of the liquid supply pipe 9. One of the threaded module 2 and the cavity wall of the installation cavity 101 is provided with a tongue 5, and the other is provided with a slot 4 for the tongue 5 to insert.

[0053] According to an embodiment of the present invention, the applicator head body includes a housing 1 and an installation bracket 100 provided inside the housing 1. The liquid supply pipe 9 is provided on the installation bracket 100. The bottom of the installation bracket 100 constitutes the bottom wall of the installation cavity 101, and a part of the housing 1 constitutes the side wall of the installation cavity 101. As Figure 6As shown, a slot 4 is provided inside the outer shell 1 along the installation direction of the thread module 2. A tongue 5 protruding upward is provided on the top surface of the thread module 2. After the thread module 2 is assembled with the outer shell 1, the tongue 5 on the top surface of the thread module 2 is inserted into the slot 4 inside the outer shell 1. That is, the wall thickness of the non-contact part between the outer wall of the outer shell 1 and the outer wall of the thread module 2 is thicker than the wall thickness of the contact part between the outer wall of the thread module 2, that is, a limiting step 102 is provided on the side wall of the installation cavity 101, and the upper surface of the thread module 2 abuts against the limiting step 102. A slot 4 matching the tongue 5 of the thread module 2 is provided in this part to facilitate the installation of the thread module 2 and can play a role in restricting the rotation of the thread module 2. In this embodiment, the thread module 2 is inserted into the slot 4 in the outer shell 1 through the tongue 5. In the direction perpendicular to the insertion direction, the size of the slot 4 is larger than that of the tongue 5, and a gap can be formed to avoid errors caused by machining accuracy and assembly accuracy. Specifically, as shown in the figure, a first gap 20 is formed between the tongue 5 and the bottom wall of the slot 4, and a second gap 21 is formed between the tongue 5 and the side wall of the slot 4. In this embodiment, the number of slots 4 can be multiple to improve the assembly accuracy and play a better limiting role at the same time.

[0054] In this embodiment, the stimulating component includes one or a combination of a massage ball, a light therapy lamp, a heating element, and a vibrator; further, it can be divided into a massage head or a light therapy head or a heating head, such as Figure 10 and Figure 11 As shown, the stimulating component is a light therapy head 22, and the light therapy head 22 is provided with a light therapy lamp. Some products on the market require massage to promote absorption, so the stimulating component in this embodiment can be a massage head; while some products require light irradiation to promote absorption, so the stimulating component in this embodiment can also be a light therapy head 22 capable of producing a light irradiation effect; while some products require heating to promote absorption, so the stimulating component in this embodiment can also be a heating head capable of producing a heating effect, and the heating head is provided with a heating element. The massage head or the light therapy head 22 or the heating head in this embodiment all belong to the prior art and will not be elaborated here.

[0055] According to an embodiment of the present invention, in this embodiment, the stimulating component is a massage head for massage, specifically as Figures 1 to 6 shown, a massage ball 13, the massage ball 13 is installed on the application head main body, at the liquid outlet end 903 at the top of the liquid supply pipe 9. The liquid supply pipe 9 can provide a conveying channel for the liquid in the liquid storage member 24 so that it can be conveyed to the massage ball 13, and the massage ball 13 is used for rolling contact with the skin surface to coat the cosmetic liquid on the skin surface.

[0056] As Figure 9 shown, Figure 9 shows a massage head provided with a double massage ball 13.

[0057] According to an embodiment of the present utility model, in this embodiment, the stimulation component further includes an electrically controlled vibrator 15. The vibrator 15 is used to drive the entire outer shell 1 to vibrate, and massage the skin during or after applying the cosmetic liquid to promote the absorption of the cosmetic liquid by the skin.

[0058] According to an embodiment of the present utility model, as Figures 3 to 7 shown, an uneven mating structure is formed between the inner side of the outer shell 1 and the outer side of the thread module 2. In this embodiment, the thread module 2 is frustum-shaped, and its bottom is provided with an internal thread 3 for connecting the cosmetic product, and the side is used to contact the inner wall of the applicator head body for assembly; the part of the outer shell 1 in contact with the thread module 2 is cylindrical, and the inner diameter of the part of the outer shell 1 in contact with the side wall of the thread module 2 is larger than the inner diameter of the part in contact with the top of the thread module 2, that is, the inner wall of the outer shell 1 is stepped to form a limiting step 102 to facilitate axial positioning when the thread module 2 is assembled with the outer shell 1.

[0059] According to an embodiment of the present utility model, as Figure 3 and Figure 6 shown, a first guiding rib (not shown in the figure) is provided on the side wall of the installation cavity 101 along the installation direction of the thread module 2, and a first guiding groove 6 corresponding to the first guiding rib is provided on the outer side wall of the thread module 2. That is, a first guiding rib is provided on the mating surface of the inner side wall of the outer shell 1 and the thread module 2 along the installation direction of the thread module 2, and a first guiding groove 6 corresponding to the first guiding rib is provided on the outer side wall of the thread module 2. By providing the first guiding rib and the first guiding groove 6, the convenience of assembly is improved; when assembling the thread module 2 into the outer shell 1, after aligning the first guiding rib and the first guiding groove 6, the thread module 2 is axially introduced along the outer applicator head body. In this embodiment, due to the provision of the first guiding rib and the first guiding groove 6, the rotation of the thread module 2 during the assembly process can be restricted, and the convenience of assembly is improved.

[0060] According to an embodiment of the present utility model, as Figures 2 to 8As shown in the figure, the application head body includes a housing 1 and a mounting bracket 100 disposed inside the housing 1. The liquid supply pipe 9 is disposed on the mounting bracket 100. The bottom of the mounting bracket 100 forms the bottom wall of the mounting cavity 101, and a part of the housing 1 forms the side wall of the mounting cavity 101. The threaded module 2 is provided with an insertion hole 8. The top surface of the threaded module 2 is butt-jointed with the bottom of the mounting bracket 100, and the liquid supply pipe 9 is inserted into the insertion hole 8. In this embodiment, the mounting bracket 100 is assembled into the housing 1 along the axial direction of the housing 1. After the threaded module 2 is assembled into the housing 1, the liquid supply pipe 9 of the threaded module 2 is inserted into the insertion hole 8. In this embodiment, to ensure the integrity and stability of the overall structure after assembly, glue can be applied at the position between the top surface of the threaded module 2 and the bottom surface of the mounting bracket 100 to improve the integrity and structural stability of the application head structure of the present utility model.

[0061] Further in this embodiment, as Figure 3 shown, a plurality of glue receiving grooves are formed on the top surface of the threaded module 2. The glue receiving grooves include an annular groove 23 and a plurality of strip grooves 7. The plurality of strip grooves 7 are located on the periphery of the annular groove 23 and are radially distributed. When using glue to bond the top surface of the threaded module 2 and the bottom surface of the mounting bracket 100, to prevent the excess glue from overflowing, a plurality of strip grooves 7 and an annular groove 23 are provided on the top surface of the threaded module 2 in this embodiment. After the two are bonded, the excess glue will converge into the strip grooves 7 and the annular groove 23. As Figure 3 shown, in this example, 4 strip grooves 7 are provided, which are located on the periphery of the annular groove 23 and are radially distributed. The glue receiving grooves can be in other shapes such as arc-shaped or annular in addition to the shape as Figure 3 shown; no specific limitation is made in the present utility model.

[0062] According to an embodiment of the present utility model, the mounting bracket 100 includes a bracket base 10 and a bracket cover 11. The liquid supply pipe 9 is integrally formed with the bracket base 10 and extends from the bottom of the bracket base 10 to the top of the bracket cover 11. The bracket base 10 and the bracket cover 11 are detachably connected. Since there are certain differences in the mounting brackets 100 adapted to different cosmetic products, mainly manifested as different lengths of the liquid supply pipes 9, so in this embodiment, the mounting bracket 100 is designed in a split manner as the bracket base 10 and the bracket cover 11. The beneficial effect brought by this split design method is that when forming the bracket base 10 by die casting, the mold for forming the liquid supply pipe 9 can be set as a replaceable part. By replacing the length of the mold for forming the liquid supply pipe 9, different bracket bases 10 can be formed, and there is no need to separately mold for different mounting brackets 100. Further reduces the production cost of the application head. In this embodiment, the bracket base 10 and the bracket cover 11 are detachably connected, and the connection method can be snap connection or threaded connection by screws.

[0063] According to an embodiment of the present utility model, as Figures 4 to 7 shown, a second guiding rib is provided on the inner side wall of the outer shell 1 along the installation direction of the installation bracket 100, and a second guiding groove 14 matching with the second guiding rib is provided on the bracket seat 10 of the installation bracket 100. For the convenience of the assembly positioning of the installation bracket 100 and to limit the degree of freedom of the installation bracket 100 after assembly to ensure the integrity of the structure, in this embodiment, a second guiding rib is provided on the inner side wall of the outer shell 1, and a second guiding groove 14 matching with the second guiding rib is provided on the bracket seat 10 of the installation bracket 100; during assembly, the second guiding rib and the second guiding groove 14 can play a guiding role, and after assembly, the second guiding rib and the second guiding groove 14 can play a role in restricting the shaking or axial rotation of the installation bracket 100.

[0064] According to an embodiment of the present utility model, the stimulating component is a massage ball 13 arranged at the top of the liquid supply pipe 9. A massage ball seat 12 for carrying the massage ball 13 is provided at the top of the installation bracket 100. The massage ball seat 12 is arranged at the top of the bracket cover 11. The massage ball seat 12 and a part of the outer shell 1 form a massage ball accommodating cavity. The massage ball 13 is limited in the massage ball accommodating cavity and is in clearance fit with the inner surface of the cavity of the massage ball accommodating cavity. The stimulating component of this embodiment is a manual stimulating component, that is, an ordinary massage ball 13. The massage ball 13 is limited in the massage ball accommodating cavity formed by the massage ball seat 12 and the outer shell 1. A part of the massage ball 13 is located outside the massage ball accommodating cavity. Since the massage ball 13 is in clearance fit with the inner surface of the cavity of the massage ball accommodating cavity, it can rotate when a user applies force. For example, when contacting the skin, it rolls on the skin surface to apply the cosmetic liquid to the skin surface and promotes the absorption of the cosmetic liquid by the skin by pressing and rolling.

[0065] According to an embodiment of the present utility model, as Figures 1 to 8 shown, it further includes a vibrator 15 arranged on the installation bracket 100, a battery 17 for supplying power to the vibrator 15, a circuit board 16 electrically connected to the vibrator 15, and a control button 18 for controlling the vibrator 15.
