Technical Field

[0001] This application relates to the technical field of beauty products, and particularly to a liquid outlet head and a liquid outlet device. Background Art

[0002] As people age, the human skin becomes loose and inelastic, and wrinkles appear. In addition, when people lack sleep or stay up late, they are prone to eye swelling and dark circles under the eyes. These problems make people look haggard and greatly affect their mental outlook. Nasolabial folds also gradually deepen with age, affecting people's appearance. Therefore, to solve the above problems, there have emerged devices for facial or eye skin care and skin care cosmetics on the market.

[0003] These skin care cosmetics usually rely on hand massage to promote absorption during use. However, it is difficult to control the strength of hand massage, resulting in poor absorption effect and reducing the user experience. Utility Model Content

Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0040] It should be noted that in the description of this application, if terms such as "first" and "second" appear, "first" and "second" are only used for the convenience of describing different components or names, and cannot be understood as indicating or implying an order relationship, relative importance, or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. Additionally, if "and / or" appears throughout the text, its meaning is that it includes three parallel scenarios. Taking "A and / or B" as an example, it includes scenario A, or scenario B, or the scenario where both A and B are satisfied simultaneously.

[0041] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a liquid outlet head 100. The liquid outlet head 100 is used to connect to a liquid supply container 200. The liquid supply container 200 includes, but is not limited to, skin care liquids such as facial cream, eye cream, toner, essence, facial cleanser, etc. When the liquid supply container 200 is connected to the liquid outlet head 100, the liquid can flow out from the liquid outlet head 100.

[0042] Please refer to Figure 3 , the liquid outlet head 100 includes a physiotherapy part 10 and a handle part 20. The physiotherapy part 10 directly contacts the skin to be cared for and is used for physiotherapy of the skin. The handle part 20 is for the user to hold, so the handle part 20 can be designed in a shape and size that is convenient for holding, such as the handle part 20 being a long circular structure or an oval structure as a whole.

[0043] Please refer to Figures 3 to 5 , specifically, the physiotherapy part 10 includes a physiotherapy outer shell 11. At least a partial outer region of the physiotherapy outer shell 11 is set as a first conductive region 1111. The physiotherapy outer shell 11 has a liquid outlet 1112 passing through the first conductive region 1111. The handle part 20 includes a handle outer shell 21. The handle outer shell 21 is for the hand to hold. At least a partial outer region of the handle outer shell 21 is set as a second conductive region 211. The second conductive region 211 is spaced from the first conductive region 1111. The liquid outlet head 100 further includes a circuit board 22. The circuit board 22 is electrically connected to the first conductive region 1111 and the second conductive region 211 respectively. One of the first conductive region 1111 and the second conductive region 211 is connected to positive electricity, and the other is connected to negative electricity.

[0044] When the user holds the handle housing 21 with their hand and touches the second conductive area 211, and at the same time touches the skin of the target area with the first conductive area 1111 of the physiotherapy housing 11, a circuit is formed among the first conductive area 1111, the human body, the second conductive area 211, and the circuit board 22. Moreover, there is a potential difference between the first conductive area 1111 and the second conductive area 211, thus forming a microcurrent on the skin of the target area. Under the action of the microcurrent, the blood circulation of the blood vessels in the target area is accelerated, and the nutrients of the skin care liquid are more fully absorbed by the human skin. On the other hand, under the action of the microcurrent, dirt such as oil on the pores of the human body is carried out with the current, realizing the function of skin cleansing.

[0045] Furthermore, since the liquid outlet 1112 is provided in the first conductive area 1111, which is equivalent to the first conductive area 1111 being arranged around the liquid outlet 1112, the liquid flowing out from the liquid outlet 1112 can be quickly affected by the microcurrent generated near the first conductive area 1111 and timely absorbed by the skin. While the liquid is being discharged, microcurrent stimulation is carried out, and the two cooperate with each other to better promote absorption.

[0046] Please refer to Figure 6 and Figure 7 Furthermore, at least a part of the area of the physiotherapy housing 11 is set as a light-transmitting area 1113. The physiotherapy part 10 further includes a light-emitting component 12 arranged in the physiotherapy housing 11. The light-emitting component 12 is arranged corresponding to the light-transmitting area 1113, and the light emitted by the light-emitting component 12 can be emitted from the light-transmitting area 1113, thereby performing physiotherapy on the skin.

[0047] The light-transmitting area 1113 can be a light-transmitting hole penetrating the physiotherapy housing 11; or, the light-transmitting area 1113 is a thin-wall area formed on the physiotherapy housing 11, and the thickness of a part of the area of the physiotherapy housing 11 is thinned to form the thin-wall area; or, the light-transmitting area 1113 is a light-transmitting cover fixed to the physiotherapy housing 11.

[0048] Please refer to Figure 11 The light-emitting component 12 includes a lamp board 121 and a light-emitting device 122 fixed to the lamp board 121. The light-emitting device 122 can be an LED (light-emitting diode), and the light-emitting device 122 can emit one of lights such as red light, infrared light, or blue light. Optionally, a plurality of light-emitting devices 122 are arranged on the lamp board 121.

[0049] Please refer to Figure 6 , Figure 8 and Figure 10, in some embodiments, the first conductive region 1111 is provided with a mounting groove 1114. The physiotherapy unit 10 further includes a light guiding structure 13, which is embedded in the mounting groove 1114, and the bottom of the mounting groove 1114 is provided with a light transmitting region 1113. The light guiding structure 13 can more evenly guide the light emitted by the light emitting device 122 outwards. By providing the mounting groove 1114, the light guiding structure 13 can be positioned and installed, reducing the risk of the light guiding structure 13 detaching from the physiotherapy housing 11. Optionally, the side of the light guiding structure 13 facing away from the bottom of the mounting groove 1114 is flush with the first conductive region 1111, so that the light guiding structure 13 and the first conductive region 1111 can simultaneously contact the skin, avoiding the situation where it is difficult for the first conductive region 1111 to contact the skin due to the light guiding structure 13 protruding outwards. Of course, since the skin is elastic, the light guiding structure 13 can also be slightly higher than the first conductive region 1111, and the elasticity of the skin can be used to adapt to the height difference between the light guiding structure 13 and the first conductive region 1111 to achieve simultaneous fitting. Alternatively, the light guiding structure 13 can also be slightly lower than the first conductive region 1111.

[0050] The shape of the mounting groove 1114 can be circular, square, annular, as long as it can cover the light transmitting region 1113, and the shape of the light guiding structure 13 is adapted to the mounting groove 1114. Optionally, the mounting groove 1114 is annular, and the light guiding structure 13 is also annular. The part of the physiotherapy housing 11 surrounded by the mounting groove 1114 is provided with a liquid outlet 1112. Thus, the liquid outlet 1112 is surrounded by the light guiding structure 13, and both the inner and outer sides of the light guiding structure 13 are the first conductive region 1111. Therefore, when the liquid flowing out from the liquid outlet 1112 acts on the target skin area, phototherapy and microcurrent stimulation are simultaneously performed on the target skin area, and the three cooperate with each other to promote the absorption of the liquid, greatly improving the use effect.

[0051] In some embodiments, the light transmitting region 1113 is a through hole penetrating the bottom of the mounting groove 1114, and the light emitting device 122 extends into the through hole, which not only avoids the light emitting device 122 being crushed and damaged by the inner wall of the physiotherapy housing 11, but also makes the light emitted by the light emitting device 122 concentrate on shooting from the through hole to the light guiding structure 13, avoiding light leakage.

[0052] Optionally, the light guiding structure 13 is bonded or welded to the physiotherapy housing 11. Taking bonding as an example, in some embodiments, the bottom of the mounting groove 1114 is further provided with a glue receiving groove 1115, and the glue receiving groove 1115 extends along the circumference of the mounting groove 1114 and is annularly arranged. The glue receiving groove 1115 can store more glue, on the one hand, improving the connection stability between the light guiding structure 13 and the physiotherapy housing 11, and on the other hand, enabling the excess glue at the bottom to overflow into the glue receiving groove 1115.

[0053] Please refer back to Figure 11, Further, a heating element 14 is also provided on the lamp board 121. The heating element 14 is in contact with the inner wall of the physiotherapy housing 11. Thus, when the heating element 14 generates heat, the heat is transferred to the physiotherapy housing 11, and further, the temperature of the first conductive region 1111 is relatively high, so as to perform hot compress when contacting the skin. The heating element 14 may specifically be a resistor, an FPC (flexible printed circuit board 22) heating sheet, a heating wire, etc. The embodiments of the present application do not limit this, as long as it can heat the physiotherapy housing 11 to make the temperature of the first conductive region 1111 relatively high.

[0054] Optionally, the heating element 14 is correspondingly arranged in the installation groove 1114. The heating element 14 can heat the position where the installation groove 1114 is located, and the light guide structure 13 is located in the installation groove 1114. Therefore, the light guide structure 13 can also be heated to a relatively high temperature. The heating element 14 transfers heat to the skin through the light guide structure 13 for hot compress, so as to promote liquid absorption and achieve a better purpose of repairing the skin.

[0055] In addition, a thermal conductive adhesive may be provided between the heating element 14 and the physiotherapy housing 11. The heating element 14 is in contact with the inner wall of the physiotherapy housing 11 through the thermal conductive adhesive. The thermal conductive adhesive has a relatively high thermal conductivity coefficient, and can quickly conduct heat to the physiotherapy housing 11 while achieving close contact with the heating element 14 and the physiotherapy housing 11. The thermal conductive adhesive can be any one of types such as polyurethane thermal conductive adhesive, epoxy resin AB adhesive, thermal conductive silicone grease, etc.

[0056] Please refer to Figure 9 , In order to position and install the heating element 14, in some embodiments, a positioning groove 1116 is provided on the inner wall of the physiotherapy housing 11, and at least a part of the heating element 14 is located in the positioning groove 1116, so that the installation position of the heating element 14 can be positioned. In addition, a thermal conductive adhesive is provided between the heating element 14 and the groove wall of the positioning groove 1116 to achieve rapid heat conduction.

[0057] In some embodiments, the physiotherapy housing 11 has a first inner wall 1117. The liquid outlet 1112 penetrates the first inner wall 1117 inward. The first inner wall 1117 is provided with a limiting convex portion 1118. The lamp board 121 abuts against the limiting convex portion 1118 and is spaced from the first inner wall 1117, and there is a gap G as shown in Figure 6 . In this way, it can be avoided that the first inner wall 1117 presses the circuits and some components on the lamp board 121. Optionally, two limiting convex portions 1118 are provided on the first inner wall 1117; or, the limiting convex portion 1118 is annular, and the heating element 14 and the light emitting device 122 are located inside the annular limiting convex portion 1118.

[0058] The heating element 14 and the light-emitting device 122 are independently electrically connected to the lamp board 121. Therefore, the heating element 14 and the light-emitting device 122 can be controlled separately, and parameters such as the heating temperature, heating duration of the heating element 14, and the light-emitting duration of the light-emitting device 122 can be adjusted separately.

[0059] In some embodiments, metal coatings are provided on the inner and outer sides of the physiotherapy housing 11 to form the first conductive region 1111, and metal coatings are provided on both the inner and outer sides of the handle housing 21 to form the second conductive region 211. In this embodiment, metal coatings can be provided on both the inner and outer sides of the entire physiotherapy housing 11. Similarly, metal coatings can be provided on both the inner and outer sides of the entire handle housing 21. Since the first conductive region 1111 and the second conductive region 211 need to be spaced apart, other structures can be provided between the physiotherapy housing 11 and the handle housing 21 for connection. Of course, the physiotherapy housing 11 and the handle housing 21 can also be directly connected, and no metal coating is provided at the connection position, so as to prevent the first conductive region 1111 and the second conductive region 211 from being always in an electrically connected state.

[0060] In other embodiments, both the physiotherapy housing 11 and the handle housing 21 are made of metal parts, so the first conductive region 1111 and the second conductive region 211 are formed by utilizing the characteristics of the metal parts themselves.

[0061] For convenient holding, the handle housing 21 is set to be strip-shaped, and the physiotherapy housing 11 is located at one end of the handle housing 21 in the length direction. Therefore, the entire liquid outlet head 100 forms a relatively long shape. In this embodiment, the physiotherapy housing 11 and the handle housing 21 are sleeved with each other in an inner and outer movable manner, and the physiotherapy housing 11 can swing relative to the handle housing 21. Specifically, there is an axial movement gap along the axial direction of the physiotherapy housing 11 between the physiotherapy housing 11 and the handle housing 21, and there is also a radial movement gap along the radial direction of the physiotherapy housing 11. Therefore, the physiotherapy housing 11 can move axially relative to the handle housing 21 and can also move radially relative to the handle housing 21, so as to achieve the swinging effect. When the first conductive region 1111 touches the skin, the physiotherapy part 10 will swing relative to the handle part 20 under the pressure of the skin, so as to adapt to the curvature of the skin through adaptive changes, and thus better fit the skin for physiotherapy.

[0062] Please refer back again to Figure 5 and Figure 7, Further, the liquid outlet head 100 further includes an elastic structure 24, and the elastic structure 24 is disposed between the handle housing 21 and the physiotherapy housing 11 to reset the physiotherapy housing 11 after the external force applied to the physiotherapy housing 11 is withdrawn. When the physiotherapy part 10 swings due to the external force of being pressed by the skin, the elastic structure 24 will be compressed or pulled. When the physiotherapy part 10 is disengaged from the skin, the external force applied by the human body on the physiotherapy part 10 disappears. At this time, the elastic structure 24 restores its elastic deformation and resets the physiotherapy part 10 to the initial position.

[0063] The elastic structure 24 can specifically adopt a spring or a silicone member. Taking the spring as an example, a liquid outlet pipe 15 is provided in the liquid outlet head 100, and the liquid outlet pipe 15 extends in the handle housing 21 and the physiotherapy housing 11. The liquid outlet pipe 15 at least forms a part of the liquid outlet channel 151. One end of the liquid outlet channel 151 is communicated with the liquid outlet 1112, and the other end of the liquid outlet channel 151 is connected to the liquid supply container 200. The elastic structure 24 is a spring sleeved on the liquid outlet pipe 15.

[0064] Further, the handle part 20 further includes a mounting bracket 212 disposed in the handle housing 21. Components such as a circuit board 22 and a battery 23 are fixed on the mounting bracket 212. The handle housing 21 is provided with a button 25. When the button 25 is triggered, it can contact the circuit board 22. The circuit board 22 is electrically connected to the lamp board 121 to control the switches of the light emitting device 122 and the heating element 14. In addition, a vibrator 26 is fixed on the circuit board 22. When the vibrator 26 is powered on, it can drive the entire physiotherapy part 10 to vibrate, thereby performing vibratory massage on the skin. A connection channel 2121 is provided on the mounting bracket 212. One end of the liquid outlet pipe 15 is communicated with the liquid outlet 1112, and the other end is inserted into the connection channel 2121, so as to position and install the liquid outlet pipe 15 at the lower end. The space in the connection channel 2121 and the liquid outlet pipe 15 together form the liquid outlet channel 151.

[0065] The spring is sleeved outside the liquid outlet pipe 15. The lower end of the spring abuts against the mounting bracket 212, and the upper end of the spring abuts against the third housing 113 (introduced in the following embodiments), so that the spring is limited in the up and down directions.

[0066] A groove 1119 is provided on the inner wall of the physiotherapy housing 11 (as Figure 6 shown), the liquid outlet 1112 penetrates through the groove wall of the groove 1119, and the end of the liquid outlet pipe 15 is inserted into the groove 1119, so as to position and install the liquid outlet pipe 15 at the upper end.

[0067] The physiotherapy housing 11 in the embodiment of the present application can be an integral housing; or, the physiotherapy housing 11 includes a plurality of housings. Specifically, the physiotherapy housing 11 includes from top to bottom ( Figure 5The first housing 111, the second housing 112, and the third housing 113 are connected in sequence in the Y direction (the Y direction in is the upward direction). The upper end of the first housing 111 is provided with a liquid outlet 1112 and a mounting groove 1114. A metal plating layer is provided on the inner and outer sides of the first housing 111 to form a first conductive region 1111. The second housing 112 can be used as a decorative structure to achieve the purpose of decoration through the change of the shape. The second housing 112 can also be set as a transparent cylindrical structure, and a lighting lamp is arranged inside to create the effect of an ambient light. The third housing 113 serves as a connecting component connecting the second housing 112 and the decorative housing 214. A limiting convex edge 1131 is provided at the lower end of the third housing 113, and a stop protrusion 2141 is provided on the inner wall of the decorative housing 214. When the entire physiotherapy part 10 moves upward by a preset distance, the limiting convex edge 1131 can abut against the stop protrusion 2141, thereby restricting the physiotherapy part 10 from continuing to move upward. After the physiotherapy part 10 moves downward by a preset distance, the lower end of the third housing 113 can abut against the decorative housing 214, thereby restricting the physiotherapy part 10 from continuing to move downward.

[0068] Similarly, the handle housing 21 can also be an integral housing; or, the handle housing 21 includes multiple housings. Specifically, the handle housing 21 includes a handle housing 213, a decorative housing 214, and a connecting housing 215. The third housing 113 and the handle housing 213 are respectively connected to the decorative housing 214. The connecting housing 215 is located at the lower end of the handle housing 213 and is fixed to the handle housing 213. Threads are provided on the inner wall of the connecting housing 215 to be fixed to the liquid supply container 200. The handle housing 213 is a long strip-shaped cylindrical structure, and metal plating layers are provided on the inner and outer sides of the handle housing 213 to form a second conductive region 211.

[0069] Please refer to Figure 1 again. Further, the liquid outlet head 100 further includes a protective cover 30. The protective cover 30 is detachably connected to the handle housing 21 and can cover the physiotherapy part 10 to protect the physiotherapy part 10.

[0070] The embodiment of the present application further provides a liquid outlet device. Please refer to Figure 1 and Figure 2 . The liquid outlet device includes a liquid supply container 200 and a liquid outlet head 100. For the specific structure of the liquid outlet head 100, please refer to the above embodiment and will not be elaborated here.

[0071] In the embodiment of the present application, the liquid supply container 200 is detachably connected to the handle housing 21, and the liquid supply container 200 is communicated with the liquid outlet 1112. Specifically, the open end of the liquid supply container 200 can be inserted into the connection housing 215 of the handle housing 21 and screwed tightly. Alternatively, clamping points are provided on the inner peripheral wall of the connection housing 215 to clamp and fix the open end of the liquid supply container 200. The liquid supply container 200 is communicated with the liquid outlet 1112 through the above-mentioned liquid supply channel. When the liquid supply container 200 is squeezed, the liquid can be extruded into the liquid supply channel and finally flows out from the liquid outlet 1112.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. 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 embodiments of the present application.
