[0002] Liquid skin care products are necessities in people's daily life. However, in cold weather, the temperature of the skin care products is too low, and applying these skin care products will irritate the skin, making the user feel extremely uncomfortable.

[0003] In order to solve this problem, the skin care products are usually heated so that the outflowing skin care products are kept at a comfortable temperature. However, the current means is to heat the entire bottle, and the skin care products in the bottle will be heated in total and will be heated every time they are used. Thus, the skin care products will be repeatedly heated to a high temperature, which is not conducive to the stability of the performance of the skin care products and accelerates the deterioration of the skin care products. CONTENT OF THE UTILITY MODEL

[0004] The main purpose of the present application is to provide a skin care product liquid outlet head and a skin care product container, which can heat the skin care products while avoiding the problem of performance change caused by repeated heating of the skin care products.

[0008] a heating element, which is arranged in the receiving gap and is used for heating the inner tube.

[0009] In an embodiment, the flow channel has a liquid inlet, and the heating element is arranged close to the liquid inlet.

[0010] In an embodiment, the aperture of the liquid inlet is smaller than the aperture of the flow channel, and the liquid inlet forms a neck relative to the flow channel.

[0011] In an embodiment, the aperture of the liquid inlet is 1.2-2 mm.

[0012] In an embodiment, the outer tube is sealingly connected to the outer peripheral surface of the inner tube at an end close to the liquid inlet.

[0013] In an embodiment, the inner tube comprises a first section, a second section and a third section connected in sequence along the axial direction, the outer diameter of the first section is larger than that of the third section, the outer diameter of the second section gradually decreases first and then gradually increases from the first section to the third section, and the liquid inlet is arranged on the third section.

[0014] The liquid outlet head further comprises a sealing ring, the sealing ring is sleeved on the second section and sealingly abuts against the second section and the outer tube.

[0015] In an embodiment, the flow channel comprises a first flow section in the first section and a second flow section in the second section, the second flow section is tapered from the first section to the third section.

[0016] In an embodiment, the heating element is attached to the inner tube, and a heat insulation layer is arranged in the receiving gap, the heat insulation layer wraps the heating element and the inner tube.

[0017] In an embodiment, the heating element is a heating sheet or a heating wire, the heating element is arranged around the inner tube; and / or,

[0018] An inner wall of the outer tube is provided with a mounting groove, the mounting groove extends to one end of the outer tube, and a temperature sensor is arranged in the mounting groove.

[0019] Embodiments of the utility model also provide a skin care product container, which comprises:

[0020] A bottle body; and

[0021] A skin care product liquid outlet head;

[0022] The liquid outlet head comprises a cover body and a dropper cap, the cover body has a clearance hole, the inner tube and the outer tube are arranged in the clearance hole and protrude from one side of the cover body facing the bottle body, and the dropper cap is fixed to the end of the inner tube and the outer tube and located on the other side of the cover body.

[0023] The technical solution in this embodiment of the invention heats the inner tube using a heating element. When the skincare product reaches the inner tube, the inner tube transfers the heat generated by the heating element to the product, raising its temperature before delivery to the user, thus avoiding irritation caused by excessively low temperatures. Furthermore, the outer tube retains the heat generated by the heating element within it, reducing heat loss and allowing the skincare product to heat up quickly, minimizing waiting time and enhancing the user experience. The outer tube is made of plastic, which has low thermal conductivity, effectively preventing heat loss. Additionally, the outer tube conceals the heating element, preventing it from being exposed and contributing to both aesthetics and protection against impact damage. Moreover, since the heating element only heats the product inside the inner tube, the product inside the bottle remains unaffected, preventing repeated heating and thus avoiding spoilage.

[0038]

[0039] DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] It should be noted that, in the description of the present application, if the terms "first", "second" and the like appear, "first", "second" are only used for convenient description of different components or names, and cannot be understood as indicating or implying the order relationship, relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features with "first", "second" can be explicitly or implicitly included at least one of the features. In addition, if "and / or" appears throughout the text, it means that it includes three parallel schemes, for example, "A and / or B", including A scheme, or B scheme, or A and B scheme.

[0042] The skin care product liquid outlet head provided in the embodiments of the present application is provided with a channel for the skin care product to flow out, and the user can apply the skin care product to the face, back, hands or other parts of the body. The types of skin care products include but are not limited to essence, eye cream, face cream, emulsion, essential oil, sunscreen, etc.

[0043] When the temperature is low in winter, the skin care product will cause irritation to the skin when contacting the skin, and a poor experience is caused to the user. In view of this, the utility model provides a liquid outlet head capable of heating the skin care product, so that the temperature of the skin care product flowing out is high, thereby providing a comfortable touch.

[0044] Please refer to Figures 1 to 7 In the embodiment of the utility model, the skin care product liquid outlet head 100 includes inner tube 10, outer tube 20 and heating piece 30, the inner tube 10 is formed with the flow channel 11 for the skin care product to flow through, the outer tube 20 is sleeved on the outer tube 10, and the outer tube 20 and the inner tube 10 have a receiving gap therebetween, and the outer tube 20 is a plastic piece; the heating piece 30 is arranged in the receiving gap, and the heating piece 30 is arranged in close contact with the inner tube 10.

[0045] Specifically, the heating piece 30 heats the inner tube 10, and when the skin care product reaches the inner tube 10, the inner tube 10 transmits the heat generated by the heating piece 30 to the skin care product, so that the skin care product is delivered to the user after the temperature of the skin care product is raised, thereby avoiding irritation to the user due to the excessively low temperature. Further, due to the arrangement of the outer tube 20, the heat generated by the heating piece 30 can be kept in the outer tube 20, and the heat loss to the outside is reduced, so that the temperature of the skin care product is rapidly raised, the waiting time of the user is reduced, and the user experience is further improved. The outer tube 20 is made of plastic, and the heat conduction efficiency of plastic is low, so that the heat generated by the heating piece 30 can be well prevented from being lost to the outside. In addition, the outer tube 20 hides the heating piece 30, and the heating piece 30 is prevented from being exposed, thereby achieving the purposes of aesthetics and preventing the heating piece 30 from being damaged by collision. Furthermore, since the heating piece 30 only heats the skin care product in the inner tube 10, the skin care product in the bottle body 200 is not affected, so that the situation that the skin care product is repeatedly heated can be avoided, thereby avoiding deterioration of the skin care product.

[0046] The inner tube 10 and the outer tube 20 are in a sleeved relationship, and the lengths of the two can be the same, of course, the lengths of the inner tube 10 and the outer tube 20 can also be different, for example, the length of the outer tube 20 is shorter than the length of the inner tube 10, and the outer tube 20 only needs to wrap the heating piece 30 and extend to a certain position at both ends of the heating piece 30.

[0047] The material of the inner tube 10 can be plastic, glass or the like, and the thermal conductivity of the inner tube 10 is greater than that of the outer tube 20, so that the heat generated by the heating piece 30 can be more rapidly conducted to the flow channel 11.

[0048] The inner tube 10 and the outer tube 20 can be made of transparent material, so that the dose of the skin care product inside can be seen. Of course, in some embodiments, a plating layer or a coating layer is arranged on the outer surface of the outer tube 20, the plating layer or the coating layer is a non-transparent structure, and a perspective window 23 (as shown in Figure 6 is arranged on the plating layer or the coating layer.

[0049] Please refer to Figures 8 to 10 In some embodiments, the flow channel 11 has an inlet 111, and the heating element 30 is arranged close to the inlet 111, so that the heating element 30 heats the skin care product close to the inlet 111, which can reduce the influence of the heat generated by the heating element 30 on the electronic elements in the cover 70, and when the liquid outlet head 100 in the form of a dropper is used, even if the amount of skin care product drawn into the inner tube 10 is small, since the skin care product is concentrated close to the inlet 111, the skin care product can be heated.

[0050] In the embodiment, the heating element 30 close to the inlet 111 means that the heating element 30 is located in the region between the middle position of the inner tube 10 in the axial direction and the inlet 111.

[0051] In some embodiments, the aperture of the inlet 111 is smaller than the aperture of the flow channel 11, and the inlet 111 forms a neck with respect to the flow channel 11. Alternatively, the aperture of the inlet 111 is much smaller than the aperture of the flow channel 11, for example, the aperture of the inlet 111 is less than one third of the aperture of the flow channel 11. Since the aperture of the inlet 111 is small, the heat in the flow channel 11 can be prevented from flowing out of the inlet 111 to some extent, which not only ensures that the heat is concentrated in the flow channel 11 to quickly heat the skin care product, but also greatly reduces the heat flowing into the bottle body 200 to repeatedly heat the skin care product in the bottle body 200.

[0052] In some embodiments, the aperture of the inlet 111 is 1.2-2mm. Specifically, the aperture of the inlet 111 can be 1.2mm, 1.5mm, 1.8mm or 2mm. When the aperture of the inlet 111 is between 1.2mm and 2mm, the skin care product can smoothly enter and exit the inlet 111, and at the same time, the inlet 111 can be as small as possible to block the heat, preventing the heat in the flow channel 11 from quickly dissipating from the inlet 111.

[0053] In some embodiments, the outer tube 20 is sealingly connected to the outer circumferential surface of the inner tube 10 at the end close to the inlet 111, so that the skin care product can be prevented from entering the accommodation gap between the outer tube 20 and the inner tube 10, and the heating element 30 can be prevented from leaking or rusting. In addition, after the outer tube 20 is sealingly connected to the outer circumferential surface of the inner tube 10 at the end close to the inlet 111, the heat generated by the heating element 30 can also be prevented from dissipating in the direction of the inlet 111, so that the heat generated by the heating element 30 can be concentrated in the accommodation gap, and the inner tube 10 has a strong heat preservation effect.

[0054] Specifically, a sealing ring 40 can be arranged between the outer tube 20 and the inner tube 10 for sealing; or a sealing glue can also be arranged between the outer tube 20 and the inner tube 10 for sealing.

[0055] Please refer again Figure 10 and Figure 11 In some embodiments, the inner tube 10 includes a first section 12, a second section 13 and a third section 14 connected in sequence along the axial direction, the outer diameter of the first section 12 is larger than that of the third section 14, and the liquid inlet 111 is arranged at the third section 14, so that the wall thickness of the third section 14 is not too large, which is beneficial to processing and saves materials.

[0056] The outer diameter of the second section 13 gradually decreases first and then gradually increases in the direction from the first section 12 to the third section 14. The liquid outlet head 100 further includes a sealing ring 40, which is sleeved on the second section 13 and sealingly abuts against the second section 13 and the outer tube 20. In this embodiment, the outer circumferential surface of the second section 13 forms an annular groove, and the sealing ring 40 can be positioned in the annular groove, so as to prevent the sealing ring 40 from moving axially. Moreover, the gradual change of the outer diameter of the second section 13 avoids the sudden change of the size of the inner tube 10, which is also beneficial to the forming of the inner tube 10 and avoids the stress problem caused by the sudden change of the size.

[0057] The outer tube 20 is tightly sleeved on the inner tube 10, and the outer tube 20 has a first abutting position P1 and a second abutting position P2 abutting against the inner tube 10. The first abutting position P1 is located at the connection between the first section 12 and the second section 13, and the second abutting position P2 is located at the connection between the second section 13 and the third section 14. In this embodiment, the size of the outer tube 20 also changes substantially along with the inner tube 10, thereby avoiding the excessive gap between the outer tube 20 and the inner tube 10. Furthermore, the first abutting position P1 and the second abutting position P2 are distributed at both ends of the sealing ring 40, which can prevent the sealing ring 40 from leaving the second section 13 and ensure the sealing between the inner tube 10 and the outer tube 20. Meanwhile, the second abutting position P2 can form a first sealing at a position close to the liquid inlet 111 to prevent liquid from entering the gap between the second section 13 and the outer tube 20. Further, the connection between the first section 12 and the second section 13 forms a step similar to a step, which limits the axial movement of the outer tube 20.

[0058] In some embodiments, the flow channel 11 includes a first flow section 112 located in the first section 12 and a second flow section 113 located in the second section 13. The hole diameter of the first flow section 112 is larger than that of the second flow section 113, and the second flow section 113 is tapered in the direction from the first section 12 to the third section 14. When the skin care product enters from the liquid inlet 111, it is released in the second flow section 113 and then gathered in the first flow section 112, thereby avoiding the blockage of the liquid inlet 111. Moreover, the change of the hole diameter of the flow channel 11 is also more suitable for the outer diameter of the inner tube 10.

[0059] The heating element 30 is attached to the first section 12, and one end of the heating element 30 is adjacent to the connection between the first section 12 and the second section 13, that is, the one end of the heating element 30 is adjacent to the first abutment position P1 described above, so that the first abutment position P1 not only reduces the heat generated by the heating element 30 from dissipating in the direction of the second abutment position P2, but also limits the heating element 30 from falling out in the direction of the second abutment position P2.

[0060] The length of the heating element 30 is substantially smaller than the length of the first section 12, so as to ensure that the heating element 30 is away from the cover 70, thereby avoiding that the heating element 30 transmits heat to the electronic elements in the cover 70 to cause the electronic elements to overheat. Optionally, the length of the heating element 30 is less than half of the length of the first section 12, where the length refers to the length in the axial direction of the inner tube 10.

[0061] The heating element 30 is attached to the inner tube 10, and in this embodiment, the attachment refers to that the bending degree of the heating element 30 is substantially the same as the bending degree of the outer circumferential surface of the inner tube 10, so that the heating element 30 and the inner tube 10 have a larger contact area. The heating element 30 can directly contact the inner tube 10, or a heat-conducting silicone grease is arranged between the heating element 30 and the inner tube 10, and the heating element 30 contacts the inner tube 10 through the heat-conducting silicone grease.

[0062] Further, the accommodation gap is also provided with a heat insulation layer 50, and the heat insulation layer 50 wraps the heating element 30 and the inner tube 10. The heat insulation layer 50 is made of a heat insulation material, and specifically, the heat insulation layer 50 can be heat insulation cotton or other plastic parts with a lower thermal conductivity than the outer tube 20. The heat insulation layer 50 can insulate the heat generated by the heating element 30, greatly reducing the heat dissipation to the outside, so as to rapidly increase the temperature in the inner tube 10 and reduce the waiting time of the user.

[0063] The heat insulation layer 50 specifically has a through-tube shape and is sleeved on the inner tube 10, and the heat insulation layer 50 enables the heating element 30 to always attach to the outer circumferential surface of the inner tube 10, thereby promoting the heat generated by the heating element 30 to be transmitted to the inner tube 10. Due to the limiting effect of the heat insulation layer 50, the heating element 30 and the inner tube 10 can not need to be additionally provided with a fixing structure.

[0064] In some embodiments, the heating element 30 is a heating sheet, and the heating sheet can have a ring-shaped closed structure, or the heating sheet has an arc shape and the two ends of the arc shape are not closed, such as an arc of a circle. In other embodiments, the heating element 30 is a heating wire, and the heating wire can have a spiral shape.

[0065] In order to be more attached, in this embodiment, the heating element 30 surrounds the inner tube 10. When a plurality of heating elements 30 are arranged, the plurality of heating elements 30 are distributed around the inner tube 10.

[0066] The heating element 30 can be positioned between the inner tube 10 and the thermal insulation layer 50 by a close fit among the inner tube 10, the outer tube 20 and the thermal insulation layer 50, and thus the heating element 30 does not need to be provided with a fixing structure to be fixed with the inner tube 10.

[0067] Further, the inner wall of the outer tube 20 is provided with a stepped surface (not shown in the figure), and one end of the heating element 30 adjacent to the liquid inlet 111 is overlapped on the stepped surface. The stepped surface can position the heating element 30 in the axial direction of the inner tube 10, and at the same time, support the heating element 30 to avoid moving along the axial direction of the inner tube 10 and to the end where the liquid inlet 111 is located. At the same time, the wrapping effect of the thermal insulation layer 50 on the heating element 30 and the inner tube 10 can limit the movement of the heating element 30.

[0068] Alternatively, in other embodiments, the outer tube 20 is bent at the end close to the liquid inlet 111 to adapt to the change of the outer diameter of the inner tube 10. Therefore, the closer to the first abutting position P1, the smaller the width of the receiving gap can be set, so as to prevent the heating element 30 from falling out.

[0069] Since the heating element 30 generates heat when powered on, the heat accumulates near the heating element 30. In order to avoid safety accidents caused by excessively high temperature near the heating element 30, in some embodiments, a temperature sensor (not shown in the figure) is further arranged between the inner tube 10 and the outer tube 20. When the temperature sensor detects that the temperature is too high, the circuit board 83 controls the heating element 30 to be powered off. In addition, when the temperature sensor detects that the temperature is too low, the circuit board 83 controls the current to increase, so that the heating element 30 can heat the skin care product to a higher temperature.

[0070] Specifically, heating the temperature of the skin care product to about 40℃, for example, between 38-45℃, can avoid cold stimulation to the skin. Considering the heat loss in the heat conduction process and other factors, the highest temperature threshold can be set to 50℃, and the lowest temperature threshold can be set to 38℃. When the temperature detected by the temperature sensor exceeds 50℃, the circuit board 83 controls the heating element 30 to be powered off. When the temperature detected by the temperature sensor is lower than 38℃, the circuit board 83 controls the current to increase, so that the heating element 30 generates more heat.

[0071] Please refer to Figure 12 , specifically, the inner wall of the outer tube 20 is provided with a mounting groove 221, the mounting groove 221 extends to one end of the outer tube 20, specifically to the end of the outer tube 20 opposite to the liquid inlet 111, and the temperature sensor is arranged in the mounting groove 221. Therefore, the temperature sensor can be inserted into the mounting groove 221 from the end away from the liquid inlet 111. Alternatively, a part of the outer tube 20 is bulged outward to form a bulge 222 (as shown in Figure 8 ), so as to form the mounting groove 221 in the inner wall of the outer tube 20.

[0072] In some embodiments, the liquid outlet head 100 is in the form of a dropper and only has the liquid inlet 111 to deliver the skin care product in the bottle 200 to the user.

[0073] Please refer to the above description again Figure 4 In the first embodiment, when the inner tube 10 and the outer tube 20 are in the form of a dropper, the liquid outlet head 100 further comprises a dropper cap 60, which is fixed at the end of the inner tube 10 and the outer tube 20, so that the end of the inner tube 10 away from the dropper cap 60 is the liquid inlet 111. By squeezing the dropper cap 60, the skin care product can enter the flow channel 11 from the liquid inlet 111. The skin care product can stay in the flow channel 11 and wait to be heated to the appropriate temperature. Then, by squeezing the dropper cap 60 again, the skin care product can flow out of the liquid inlet 111.

[0074] The liquid outlet head 100 further comprises a cover 70, which has a clearance hole 71. The inner tube 10 and the outer tube 20 pass through the clearance hole 71 and protrude from one side of the cover 70. The dropper cap 60 is fixed at the end of the inner tube 10 and the outer tube 20 and is located on the other side of the cover 70.

[0075] The cover 70 is provided with a battery 82 and a circuit board 83 inside. The outer surface of the cover is further provided with a switch button 84. The battery 82, the circuit board 83 and the heating element 30 are electrically connected. When the switch button is triggered, the battery 82 supplies power to the heating element 30.

[0076] In some embodiments, the cover 70 comprises a top cover 72 and a bottom cover 73, which are fixed to jointly form a containing space. The containing space is provided with the battery 82 and the circuit board 83. The clearance hole 71 comprises a first hole located on the top cover 72 and a second hole located on the bottom cover 73. The dropper cap 60 is located on the top cover 72. The dropper cap 60 is provided with an annular clamping groove 61 (as shown in Figure 11 The top cover 72 is clamped into the annular clamping groove 61 at the hole edge position of the first hole.

[0077] Further, the bottom cover 73 is further provided with a heat blocking wall 731, which surrounds the second hole and protrudes into the containing space. The heat blocking wall 731 separates the electronic components such as the battery 82 and the circuit board 83 from the outer tube 20, so as to avoid the heat generated by the heating element 30 from being transmitted to the electronic components.

[0078] The inner periphery of the heat blocking wall 731 is provided with an internal thread. The bottle mouth of the bottle 200 is provided with an external thread to be screwed with the internal thread, so as to fix the bottle 200 with the cover 70. Of course, in other embodiments, the cover 70 and the bottle 200 can be directly inserted and matched, and clamped by buckling.

[0079] Further, the end of the heat blocking wall 731 is also provided with a sealing ring 81, the outer circumferential surface of the sealing ring 81 is provided with an annular groove (not shown in the figure), and the annular groove is clamped with the end of the heat blocking wall 731. Please refer to Figure 12 The outer tube 20 comprises a large tube segment 21 and a small tube segment 22 which are connected with each other, the connecting position of the large tube segment 21 and the small tube segment 22 forms a stepped surface, the stepped surface abuts against the sealing ring 81, and the sealing ring 81 is sealingly sleeved on the small tube segment 22. In this way, the sealing ring 81 can prevent the liquid in the bottle body 200 from flowing out of the second hole.

[0080] Further, the large tube segment 21 is provided with a wire passing hole 211, so that the wire between the circuit board 83 and the heating element 30 passes through.

[0081] Please refer to Figure 2 The bottom cover 73 is provided with a support rib 732, the battery 82 and the circuit board 83 are overlapped on the support rib 732, so that the battery 82 and the circuit board 83 have a gap with the side of the bottom cover 73 which faces the top cover 72, and part of the gap can be used for the heat generated by the battery 82 and the circuit board 83 to flow, thereby achieving the effect of heat dissipation.

[0082] Please refer to Figure 5 The top cover 72 is provided with a plurality of limiting ribs 721 which are distributed along the circumference of the battery 82 and the circuit board 83, the plurality of limiting ribs 721 combine to form a space which is approximately a groove, the battery 82 and the circuit board 83 are located in the groove-shaped space, and the limiting ribs 721 are in contact with the battery 82 and the circuit board 83, thereby limiting the battery 82 and the circuit board 83.

[0083] In the second embodiment, when the inner tube 10 and the outer tube 20 adopt the form of a dropper, the liquid outlet head 100 further comprises a pump head (not shown in the figure), the pump head is arranged at the end of the inner tube 10 which is away from the liquid inlet 111, and the pump head is movably connected with the cover body 70. By pressing the pump head once, the pump head rebounds, and the inner tube 10 can draw the skin care product in the bottle body 200 into the flow channel 11 for heating. Then, the skin care product can flow out of the liquid inlet 111 by pressing the pump head again.

[0084] In other embodiments, the liquid outlet head 100 adopts the form of a press pump and is provided with a liquid inlet 111 and a liquid outlet at the same time to deliver the skin care product. Specifically, the inner tube 10 is provided with a liquid inlet 111 and a liquid outlet, and the cover body 70 is provided with a press pump (not shown in the figure).
