[0001] The present application relates to the technical field of skin care product containers, and in particular to a skin care product liquid dispensing head and a skin care product container. Background Art

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

[0003] In order to solve this problem, the skin care products are usually heated to keep the discharged skin care products at a comfortable temperature. However, the current method is to heat the entire bottle, and all the skin care products in the bottle will be heated, and the skin care products will be heated once each time they are used. In this way, the skin care products will be repeatedly heated to a higher 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. Summary of the invention

[0004] The main purpose of the present invention is to provide a skin care product dispensing head and a skin care product container, aiming to provide a heated skin care product while avoiding the problem of performance changes caused by repeated heating of the skin care product.

[0005] To achieve the above-mentioned purpose, the present invention provides a skin care product liquid dispensing head, comprising:

[0006] An inner tube, wherein the inner tube is formed with a flow channel for the skin care product to flow;

[0007] An outer tube, the outer tube is sleeved outside the inner tube, a receiving gap is defined between the outer tube and the inner tube, and the outer tube is a plastic part; and,

[0008] A heating element is disposed in the storage gap and is used to heat the inner tube.

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

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

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

[0012] In one embodiment, the outer tube is sealedly connected to the outer circumferential surface of the inner tube at one end close to the liquid inlet.

[0013] In one 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 greater than the outer diameter of the third section, the outer diameter of the second section gradually decreases and then gradually increases in a direction from the first section to the third section, and the liquid inlet is arranged in the third section;

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

[0015] In one embodiment, the flow channel includes a first flow segment located in the first segment, and a second flow segment located in the second segment, and the second flow segment is tapered in a direction from the first segment to the third segment.

[0016] In one embodiment, the heating element is fitted with the inner tube, and a heat insulation layer is further provided in the storage gap, and the heat insulation layer wraps the heating element and the inner tube.

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

[0018] The 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 provided in the mounting groove.

[0019] The embodiment of the present invention further provides a skin care product container, comprising:

[0020] Bottle; and

[0021] Skin care product dispenser;

[0023] The technical solution in the embodiment of the present invention is to heat the inner tube by a heating element. When the skin care product reaches the inner tube, the inner tube transfers the heat generated by the heating element to the skin care product, so that the skin care product is delivered to the user after the temperature rises, thereby avoiding irritation to the user due to too low temperature. Further, due to the setting of the outer tube, the heat generated by the heating element can be kept in the outer tube, reducing the heat loss to the outside, so that the temperature of the skin care product rises quickly, reducing the waiting time of the user, and further improving the user experience.

In addition, the outer tube also hides the heating element inside, avoiding the exposure of the heating element, achieving the purpose of beauty and preventing the heating element from being damaged by collision. Furthermore, since the heating element only heats the skin care product in the inner tube, the skin care product in the bottle body is not affected, so it can avoid the situation where the skin care product is repeatedly heated, thereby avoiding the deterioration of the skin care product.

[0039] DETAILED DESCRIPTION

[0040] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0041] 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 indicated technical features. 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 that it includes three parallel solutions, taking "A and / or B as an example", including solution A, or solution B, or a solution that satisfies both A and B.

[0042] The embodiment of the present invention provides a skin care product dispensing head, which 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, lotion, essential oil, sunscreen, etc.

[0043] In winter, when the temperature is low, skin care products will irritate the skin when they come into contact with the skin, giving the user a very bad experience. To address this, an embodiment of the present invention provides a liquid outlet head that can heat the skin care products, so that the temperature of the skin care products flowing out is higher, thereby providing a comfortable touch.

[0044] Please refer to Figures 1 to 7 In the embodiment of the present invention, the skin care product liquid discharge head 100 includes an inner tube 10, an outer tube 20 and a heating element 30. The inner tube 10 forms a flow channel 11 for the skin care product to flow; the outer tube 20 is sleeved outside the inner tube 10, and there is a storage gap between the outer tube 20 and the inner tube 10. The outer tube 20 is a plastic part; the heating element 30 is arranged in the storage gap, and the heating element 30 is arranged in close contact with the inner tube 10.

[0045] Specifically, the heating element 30 heats the inner tube 10. When the skin care product reaches the inner tube 10, the inner tube 10 transfers the heat generated by the heating element 30 to the skin care product, so that the skin care product is delivered to the user after the temperature rises, thereby avoiding irritation to the user due to too low temperature. Further, due to the setting of the outer tube 20, the heat generated by the heating element 30 can be kept in the outer tube 20, reducing the heat loss to the outside, so that the temperature of the skin care product rises quickly, reducing the waiting time of the user, and further improving the user experience. The outer tube 20 is made of plastic, and the heat conduction efficiency of plastic is low, so it can well avoid the heat generated by the heating element 30 from being lost to the outside. In addition, the outer tube 20 also hides the heating element 30 inside, avoiding the exposure of the heating element 30, achieving the purpose of beauty and preventing the heating element 30 from being damaged by collision. Furthermore, since the heating element 30 only heats the skin care product in the inner tube 10, the skin care product in the bottle 200 is not affected, so it can avoid the situation where the skin care product is repeatedly heated, thereby avoiding the deterioration of the skin care product.

[0046] The inner tube 10 and the outer tube 20 are arranged inside and outside, 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. The outer tube 20 only needs to wrap around the heating element 30 and extend to certain positions at both ends of the heating element 30.

[0047] The material of the inner tube 10 can be plastic, glass, etc. 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 element 30 can be conducted to the flow channel 11 more quickly.

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

[0049] Please refer to Figures 8 to 10 In some embodiments, the flow channel 11 has a liquid inlet 111, and the heating element 30 is arranged near the liquid inlet 111. Therefore, the heating element 30 heats the skin care product at a position close to the liquid inlet 111, which can reduce the influence of the heat generated by the heating element 30 on the electronic components in the cover body 70. Moreover, when a dropper-shaped liquid outlet head 100 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 at a position close to the liquid inlet 111, it can also be ensured that the skin care product can be heated.

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

[0051] In some embodiments, the aperture of the liquid inlet 111 is smaller than the aperture of the flow channel 11, and the liquid inlet 111 forms a constriction relative to the flow channel 11. Optionally, the aperture of the liquid inlet 111 is much smaller than the aperture of the flow channel 11, for example, the aperture of the liquid inlet 111 is less than one-third of the aperture of the flow channel 11. Since the aperture of the liquid inlet 111 is small, it can prevent the heat in the flow channel 11 from flowing out of the liquid inlet 111 to a certain extent, which ensures that the heat is gathered in the flow channel 11 to quickly heat the skin care products, and greatly reduces the heat flowing into the bottle body 200, causing the skin care products in the bottle body 200 to be repeatedly heated.

[0052] In some embodiments, the aperture of the liquid inlet 111 is 1.2-2 mm. Specifically, the aperture of the liquid inlet 111 may be 1.2 mm, 1.5 mm, 1.8 mm or 2 mm. When the aperture of the liquid inlet 111 is between 1.2-2 mm, while ensuring that the skin care products can smoothly enter and exit the liquid inlet 111, the liquid inlet 111 can be made as small as possible, thereby blocking heat and preventing the heat in the flow channel 11 from being quickly dissipated from the liquid inlet 111.

[0053] In some embodiments, the outer tube 20 is sealed and connected to the outer circumference of the inner tube 10 at one end near the liquid inlet 111, so as to prevent the skin care products from entering the storage gap between the outer tube 20 and the inner tube 10, and prevent the heating element 30 from leaking or rusting. In addition, the outer tube 20 is sealed and connected to the outer circumference of the inner tube 10 at one end near the liquid inlet 111, which can also prevent the heat generated by the heating element 30 from dissipating toward the liquid inlet 111. Therefore, the heat generated by the heating element 30 can be gathered in the storage gap, which has a strong heat preservation effect on the inner tube 10.

[0054] Specifically, a sealing ring 40 may be provided between the outer tube 20 and the inner tube 10 for sealing; or, a sealant may be provided between the outer tube 20 and the inner tube 10 for sealing.

[0055] Please refer to it again Fig.10 and Fig.11 In some embodiments, the inner tube 10 includes a first section 12, a second section 13 and a third section 14 which are sequentially connected along the axial direction. The outer diameter of the first section 12 is greater than the outer diameter of the third section 14. The liquid inlet 111 is arranged in the third section 14. Therefore, the wall thickness of the third section 14 is not too large, which is conducive to processing and material saving.

[0056] The outer diameter of the second section 13 gradually decreases and then gradually increases in the direction from the first section 12 to the third section 14. The liquid outlet head 100 also includes a sealing ring 40, which is sleeved on the second section 13 and seals against the second section 13 and the outer tube 20. In this embodiment, the outer peripheral surface of the second section 13 is equivalent to forming an annular groove, and the sealing ring 40 can be limited in the annular groove, thereby preventing the sealing ring 40 from moving in the axial direction. In addition, the gradual change of the outer diameter of the second section 13 avoids the sudden change in the size of the inner tube 10, which is also conducive to the molding of the inner tube 10 and avoids the stress problem caused by the sudden change in size.

[0057] The outer tube 20 is tightly sleeved on the inner tube 10. 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 basically changes with the inner tube 10, thereby avoiding an excessively large 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, thereby ensuring the sealing between the inner tube 10 and the outer tube 20. At the same time, the second abutting position P2 can also form a first seal at a position close to the liquid inlet 111, preventing the 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 the outer tube 20 axial movement.

[0058] In some embodiments, the flow channel 11 includes a first flow segment 112 located in the first segment 12, and a second flow segment 113 located in the second segment 13. The aperture of the first flow segment 112 is larger than the aperture of the second flow segment 113, and the second flow segment 113 is gradually reduced in the direction from the first segment 12 to the third segment 14. When the skin care product enters from the liquid inlet 111, it is released in the second flow segment 113 and then gathered in the first flow segment 112, thereby avoiding the blockage of the liquid inlet 111. In addition, the change in the aperture of the flow channel 11 is also more compatible with 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, one end of the heating element 30 is adjacent to the above-mentioned first abutment position P1. Therefore, the first abutment position P1 can not only reduce the heat generated by the heating element 30 from being dissipated in the direction of the second abutment position P2, but also limit the heating element 30 to prevent 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 much shorter than the length of the first section 12, so that the heating element 30 can be kept away from the cover 70, thereby preventing the heating element 30 from transferring heat to the electronic components in the cover 70 and causing the electronic components to overheat. Optionally, the length of the heating element 30 is less than half the length of the first section 12, where the length refers to the length along the axial direction of the inner tube 10.

[0061] The heating element 30 is fitted with the inner tube 10. The fitting in this embodiment means that the curvature of the heating element 30 is substantially the same as the curvature of the outer circumference 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 and the inner tube 10 can be in direct contact, or thermal conductive silicone grease is provided between the two, and the heating element 30 contacts the inner tube 10 through the thermal conductive silicone grease.

[0062] Furthermore, a heat insulating layer 50 is provided in the storage gap, and the heat insulating layer 50 is wrapped around the heating element 30 and the inner tube 10. The heat insulating layer 50 is made of heat insulating material, specifically, the heat insulating layer 50 can be heat insulating cotton or other plastic parts with lower thermal conductivity than the outer tube 20. The heat insulating layer 50 can isolate the heat generated by the heating element 30, greatly reducing the heat loss to the outside, so that the temperature in the inner tube 10 rises quickly, reducing the waiting time of the user.

[0063] The heat insulating layer 50 is specifically in the shape of a tube with two through ends and is sleeved on the inner tube 10, and the heat insulating layer 50 enables the heating element 30 to always fit on the outer peripheral surface of the inner tube 10, thereby promoting the heat transfer of the heating element 30 to the inner tube 10. Due to the limiting effect of the heat insulating layer 50, there is no need to set an additional fixing structure between the heating element 30 and the inner tube 10.

[0064] In some embodiments, the heating element 30 is a heating plate, which may be a ring-shaped closed structure, or the heating plate is arc-shaped and the ends of the arc are not closed, such as the heating plate is arc-shaped. In other embodiments, the heating element 30 is a heating wire, which may be spiral.

[0065] For better fit, in this embodiment, the heating element 30 is disposed around the inner tube 10. When a plurality of heating elements 30 are provided, the plurality of heating elements 30 are distributed around the inner tube 10.

[0066] The heating element 30 can be limited between the inner tube 10 and the thermal insulation layer 50 through the tight fit between the inner tube 10, the outer tube 20 and the thermal insulation layer 50, so the heating element 30 does not need to be fixed with the inner tube 10 by a fixing structure.

[0067] Furthermore, the inner wall of the outer tube 20 is provided with a stepped surface (not shown), and one end of the heating element 30 adjacent to the liquid inlet 111 overlaps the stepped surface, which can position the axial position of the heating element 30 in the inner tube 10 and support the heating element 30 to prevent the heating element 30 from moving along the axial direction of the inner tube 10 and toward the end where the liquid inlet 111 is located. At the same time, the wrapping effect of the heat 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 one end near the liquid inlet 111 in order to adapt to the change in the outer diameter of the inner tube 10. Therefore, the width of the storage gap can be set to be smaller as it is closer to the first abutment position P1, thereby preventing the heating element 30 from falling out.

[0069] Since the heating element 30 generates heat when it is powered on, the heat accumulates near the heating element 30. In order to avoid safety accidents caused by excessively high temperatures near the heating element 30, in some embodiments, a temperature sensor (not shown) is further provided 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 detected by the temperature sensor is too low, the circuit board 83 controls the current to increase, so that the heating element 30 can heat the skin care products to a higher temperature.

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

[0071] Please refer to Fig.12 Specifically, the inner wall of the outer tube 20 is provided with a mounting groove 221, which 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 a temperature sensor is provided 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. Optionally, a part of the outer tube 20 bulges outward to form a bulge 222 (such as Figure 8 As shown), a mounting groove 221 is formed on 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 is only provided with a liquid inlet 111 to deliver the skin care product in the bottle body 200 to the user.

[0073] Please refer to it 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 also includes a dropper cap 60, which is fixed to the ends 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 a liquid inlet 111. By squeezing the dropper cap 60, the skin care product can enter the flow channel 11 from the liquid inlet 111, and the skin care product can stay in the flow channel 11, waiting to be heated to a suitable temperature, and then squeezing the dropper cap 60, and the skin care product flows out from the liquid inlet 111.

[0074] The liquid discharge head 100 also includes a cover body 70, which has a clearance hole 71. The inner tube 10 and the outer tube 20 are inserted into the clearance hole 71 and protrude from one side of the cover body 70. The dropper cap 60 is fixed to the ends of the inner tube 10 and the outer tube 20 and is located on the other side of the cover body 70.

[0075] A battery 82 and a circuit board 83 are disposed in the cover body 70 , and a switch button 84 is also disposed on the outer surface of the box body. 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 body 70 includes a top cover 72 and a bottom cover 73, and the top cover 72 and the bottom cover 73 are fixed to form a receiving space together, and the receiving space is provided with a battery 82 and a circuit board 83. The clearance hole 71 includes a first hole located in the top cover 72 and a second hole located in the bottom cover 73. The dropper cap 60 is located on the top cover 72, and the dropper cap 60 is provided with an annular groove 61 (such as Fig.11 As shown in FIG. 1 , the top cover 72 is inserted into the annular groove 61 at the edge of the first hole.

[0077] Furthermore, the bottom cover 73 is also provided with a heat shield wall 731, which surrounds the second hole and protrudes into the accommodating space. The heat shield wall 731 separates electronic components such as the battery 82 and the circuit board 83 from the outer tube 20, thereby preventing the heat generated by the heating element 30 from being transferred to the electronic components.

[0078] The inner circumference of the heat shield wall 731 is provided with an internal thread, and the bottle mouth of the bottle body 200 is provided with an external thread to be screwed with the internal thread, thereby fixing the bottle body 200 and the cover body 70. Of course, in other embodiments, the cover body 70 and the bottle body 200 can also be directly plugged and matched, and clamped by buckles.

[0079] Furthermore, a sealing ring 81 is provided at the end of the heat shielding wall 731, and the outer peripheral surface of the sealing ring 81 has an annular groove (not shown in the figure), and the annular groove is clamped with the end of the heat shielding wall 731. Fig.12 The outer tube 20 includes a large tube section 21 and a small tube section 22 connected to each other, and a step surface is formed at the connection position of the large tube section 21 and the small tube section 22, and the step surface abuts against the sealing ring 81, and the sealing ring 81 is sealed on the small tube section 22. In this way, the sealing ring 81 can prevent the liquid in the bottle body 200 from flowing out from the second hole.

[0080] Furthermore, the large pipe section 21 is provided with a wire passage 211 to allow the wires between the circuit board 83 and the heating element 30 to pass through.

[0081] Please refer to Figure 2 The bottom cover 73 is provided with supporting ribs 732, and the battery 82 and the circuit board 83 are overlapped on the supporting ribs 732, so that there is a gap between the battery 82 and the circuit board 83 and the side of the bottom cover 73 facing the top cover 72, and the heat generated by the battery 82 and the circuit board 83 can flow in part of the gap, thereby achieving a heat dissipation effect.

[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 are combined to enclose a space that is approximately in the shape of a groove. The battery 82 and the circuit board 83 are located in the groove-shaped space. 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 are in the form of a dropper, the liquid outlet head 100 further includes a pump head (not shown), which is disposed at one end of the inner tube 10 away from the liquid inlet 111, and is movably connected to 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 200 into the flow channel 11 for heating. Then, the pump head is pressed again, and the skin care product can flow out from the liquid inlet 111.
