For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0076] Currently, when users apply skincare products such as essential oils and serums, they often heat the entire bottle using a heating device to improve absorption. However, this process involves repeatedly heating the entire bottle each time a user needs to use the product, which can affect its effectiveness and also results in longer waiting times, thus impacting the user experience.

[0077] To address the aforementioned technical problems, this application provides a bottle cap and container that effectively solves the problem of repeatedly heating the entire bottle of skincare product by introducing the skincare product inside the bottle into the bottle cap for heating.

[0078] In some embodiments, refer to Figures 1 to 25 As shown, this application provides a bottle cap, including: a cap body 1, a heating assembly 2, a liquid guiding tube 3, and a liquid suction / draining assembly 4. The cap body 1 is connected to a bottle body 5; the heating assembly 2 includes a heating chamber 6 and a heating element 7 disposed within the cap body 1, the heating element 7 being used to heat the heating chamber 6; the liquid guiding tube 3 is connected to the heating chamber 6, and one end of the liquid guiding tube 3 away from the heating chamber 6 extends into the bottle body 5; the liquid suction / draining assembly 4 is disposed on the cap body 1 and connected to the heating chamber 6, used to control the intake of skincare products from the bottle body 5 into the heating chamber 6 or to control the discharge of skincare products from the heating chamber 6.

[0079] Specifically, the cap 1, as the main body of the entire bottle cap, connects to the bottle opening 8 at the top of the skincare bottle 5 and supports all other components. The heating chamber 6, located inside the cap 1, is a space for storing skincare products. The heating element 7, which can be a small heat-generating component such as a heating wire or resistance heating element, heats the skincare products inside the chamber. The liquid guide tube 3 connects the heating chamber 6 to the inside of the bottle 5, guiding the skincare products into the heating chamber 6. The liquid guide tube 3 and the heating chamber 6 can be a single, integrally formed structure. Figure 4 As shown; the liquid guide tube 3 and the heating chamber 6 can also be separate structures, such as... Figure 8 and Figure 23 As shown. The suction and discharge component 4 is mainly used to control the entry of skin care products into the heating chamber 6 and to discharge them after heating for user use.

[0080] When a user needs to heat a certain amount of skincare product, the appropriate amount is first drawn into the heating chamber 6 via the liquid inlet tube 3 using the suction and discharge component 4. The heating element 7 then activates, heating the product in the heating chamber 6 to ensure that only the portion about to be used is affected by the temperature. Once heating is complete, the suction and discharge component 4 again discharges the heated product from the heating chamber 6, directly supplying it to the user. This not only reduces the chance of the entire bottle of skincare product being repeatedly heated, thus preserving the active ingredients, but also effectively shortens the user's waiting time, as it eliminates the need to heat the entire bottle.

[0081] Therefore, the bottle cap provided in this application embodiment can avoid repeatedly heating the entire bottle of skincare product, improving the efficiency and effectiveness of skincare product use, while ensuring that the product quality is not damaged. Furthermore, the instant heating function ensures an optimal skincare experience every time it is used.

[0082] In actual use, the skin care product in the bottle 5 is introduced into the heating chamber 6 inside the bottle cap through the liquid guide tube 3. The heating component 7 only heats the skin care product in the heating chamber 6. However, since there is also some skin care product in the liquid guide tube 3, it will affect the temperature of the skin care product in the heating chamber 6, especially when the liquid guide tube 3 is long and the ambient temperature is low.

[0083] To address the issue of residual skincare products in the infusion tube 3 affecting temperature, refer to... Figures 7 to 12 As shown, the bottle cap in some embodiments of this application also includes a flow-stopping and venting valve 9. The flow-stopping and venting valve 9 is connected between the heating chamber 6 and the liquid guiding tube 3. The flow-stopping and venting valve 9 includes a valve body 10 and a valve core 11. The valve body 10 includes a main flow chamber 12 and a bypass chamber 13. One end of the main flow chamber 12 is connected to the heating chamber 6, and the other end of the main flow chamber 12 is connected to the liquid guiding tube 3. A first vent 14 is connected between the bypass chamber 13 and the main flow chamber 12, and a second vent 15 is provided on the side of the bypass chamber 13 away from the first vent 14. The valve core 11 can move in the bypass chamber 13 during the control process of the liquid suction and discharge assembly 4 to switch between a first position, a second position, and a third position. In the first position, the valve core 11 blocks the first vent 14; in the second position, the valve core 11 opens the first vent 14 and the second vent 15; in the third position, the valve core 11 blocks the second vent 15.

[0084] Specifically, the valve body 10 comprises two parts: a main flow chamber 12 and a bypass chamber 13. The main flow chamber 12 connects the heating chamber 6 and the liquid guide tube 3, ensuring that skincare products can enter and exit. The bypass chamber 13 houses the valve core 11 and regulates the airflow direction through the first vent 14 and the second vent 15. The valve core 11, as a movable component, can be a lightweight valve ball that switches positions within the bypass chamber 13 according to different operating stages to control the airflow path and ultimately control the flow of the skincare product liquid.

[0085] The main function of the stop-flow and exhaust valve 9 is to achieve different airflow and liquid flow control in the three control stages of skin care product extraction, stopping extraction and discharge, so as to ensure the accuracy and efficiency of the heating process.

[0086] Skincare product extraction stage: such as Figure 10 As shown, at this stage, the suction and discharge assembly 4 starts working, drawing the skincare product from the bottle 5 into the heating chamber 6 via the liquid guide tube 3. As the skincare product is drawn into the heating chamber 6, the internal air pressure decreases. This pressure change pushes the valve core 11 to the first position, sealing the first air hole 14 to prevent outside air from entering the heating chamber 6, thereby ensuring that the skincare product can be smoothly drawn into the heating chamber 6.

[0087] Stop extraction phase: such as Figure 11 As shown, once the heating chamber 6 is saturated with skincare products, the suction and discharge assembly 4 stops working and ceases suction. Since no new air pressure acts on the valve core 11, it automatically descends to the second position. At this point, the first air hole 14 and the second air hole 15 are connected, allowing air to pass through both ends of the liquid guide tube 3, breaking the balance. The remaining skincare products in the liquid guide tube 3 automatically flow out due to gravity. However, the skincare products inside the heating chamber 6 do not flow out because the internal air pressure remains unchanged, and they remain inside the heating chamber 6 for heating.

[0088] Eliminating skincare products during the elimination stage: such as Figure 12 As shown, after heating is complete, when the heated skincare product needs to be discharged for user use, the suction and discharge assembly 4 is activated again, but this time to push the skincare product in the heating chamber 6 outward. During the discharge process, under the action of air pressure, the valve core 11 moves to the third position, blocking the second air hole 15, ensuring that the heated skincare product can be smoothly discharged through the liquid guide tube 3.

[0089] Therefore, in this embodiment, the residual skincare product in the liquid guide tube 3 can be discharged through the vent valve 9, leaving only the skincare product needed in the heating chamber 6 for heating. This design not only improves heating accuracy but also reduces user waiting time, as it ensures that only the actual skincare product needed is heated each time. Furthermore, it simplifies the user's operation process, enhances product usability, and further improves the overall user experience.

[0090] In other embodiments, reference is made to Figure 13 and Figure 14 As shown, the liquid guiding tube 3 includes multiple tube segments 16 that are sequentially connected and can expand and contract relative to each other.

[0091] Specifically, the liquid-conducting tube 3 consists of multiple tube segments 16, each of which can slide and embed itself into adjacent tube segments 16 like a telescope. This design allows the liquid-conducting tube 3 to contract into a compact form when not in use or when it needs to be emptied, and to extend to an appropriate length when skincare products need to be extracted. When the user is ready to use the skincare product, the liquid-conducting tube 3 is fully extended. Before heating the skincare product, the user can retract the liquid-conducting tube 3 to its shortest state. As the liquid-conducting tube 3 shortens, its internal space also decreases, which effectively forces any remaining skincare product in the liquid-conducting tube 3 to flow out, thus preventing this skincare product from affecting the temperature of the skincare product that is about to be heated.

[0092] Therefore, this embodiment of the application, through the retractable design of the liquid guide tube 3, can quickly empty any residual skincare product inside the liquid guide tube 3, ensuring that only the skincare product in the heating chamber 6 is heated, and is not affected by the temperature of the residual skincare product in the liquid guide tube 3, thus guaranteeing that the skincare product reaches the set temperature every time it is used. Furthermore, when not in use, the retracted liquid guide tube 3 occupies less space, making the entire bottle cap structure more compact and easier to carry.

[0093] In some embodiments, refer to Figure 4 , Figure 8 and Figure 23 As shown, the cross-sectional area of ​​the liquid guide tube 3 is smaller than the cross-sectional area of ​​the heating chamber 6.

[0094] Specifically, the heating chamber 6 is a space for storing and heating skincare products. Its large cross-sectional area allows it to hold more products and provides sufficient space for even heating. Conversely, its smaller cross-sectional area allows for faster flow of skincare products within the liquid guide tube 3, reducing the time required to extract products and improving overall operational efficiency. Furthermore, the thinner liquid guide tube 3 helps reduce the amount of skincare product residue within the tube, ensuring freshness and hygiene, while also facilitating cleaning and maintenance.

[0095] Understandably, when skincare products enter the heating chamber 6, due to the small cross-sectional area of ​​the liquid guide tube 3, the skincare products will quickly diffuse into the larger space of the heating chamber 6, allowing heat to be transferred to the skincare products more quickly and evenly, thereby improving heating efficiency.

[0096] Therefore, through the above design, the embodiments of this application not only optimize the flow path and heating efficiency of skin care products, but also enhance the compactness and hygiene of the device.

[0097] In some embodiments, refer to Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the heating component 7 includes an insulation box 17 and a heating element 18. The insulation box 17 covers the heating chamber 6, and the two ends of the insulation box 17 are provided with through holes for the heating chamber 6 to pass through. The heating element 18 is located between the heating chamber 6 and the insulation box 17.

[0098] Specifically, the insulated box 17 is installed outside the heating chamber 6, serving to isolate the heating chamber 6 from the external environment. The insulated box 17 has through holes at the top and bottom, allowing the heating chamber 6 to pass through and connect to the liquid guide tube 3 and the liquid suction / drainage assembly 4, ensuring that skincare products can smoothly enter and exit the heating chamber 6. The insulated box 17 can be made of materials with good thermal insulation properties (such as foam plastic, fiberglass, etc.) to reduce heat loss and improve the heating rate.

[0099] The heating element 18 is installed in the space between the heating chamber 6 and the insulation box 17, directly heating the heating chamber 6. The specific type of the heating element 18 is not particularly limited; a suitable type can be selected based on actual usage requirements. For example, ... Figure 15 As shown, the heating element 18 can be a heating plate, including a ceramic heating plate, a mica heating plate, a PTC heating plate, etc. Figure 16 As shown, the heating element 18 can also be a flexible heating plate, including graphene heating plates, silicone rubber heating plates, polyimide heating films, etc. Figure 17 As shown, the heating element 18 can also be an alumina heating ceramic tube.

[0100] Heating process: When skincare products need to be heated, the heating element 18 is activated, quickly transferring heat to the skincare products inside the heating chamber 6. Due to the presence of the insulated box 17, most of the heat is retained near the heating chamber 6, reducing heat loss and allowing the skincare products to reach the required temperature in a short time.

[0101] Heat preservation process: When the skin care product reaches the set temperature, the heating element 18 can reduce its power or stop working as needed, while the heat preservation box 17 continues to play its role, slowing down heat loss and maintaining the skin care product in a relatively stable temperature range, waiting for the user to use it.

[0102] Therefore, this embodiment of the application achieves rapid heating of skin care products by combining the heating element 18 and the heat preservation box 17, shortening the user's waiting time, improving heating efficiency while ensuring the temperature stability of skin care products, and solving the problems of large heat loss and long heating time in traditional heating methods.

[0103] In some embodiments, refer to Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the heating component 7 also includes a heat-conducting seat 19 disposed in the heat preservation box 17. The heat-conducting seat 19 is sleeved on the heating chamber 6, and a heating element 18 is disposed on the heat-conducting seat 19.

[0104] Specifically, the heat-conducting base 19 is a heat-conducting kit with openings at both ends, fitted onto the heating chamber 6. It provides uniform heat conduction to the heating chamber 6 while also offering some protection and improving the overall structural strength. Furthermore, it can secure the heating element 18. The heat-conducting base 19 can be made of ceramic material. Ceramic has excellent thermal conductivity and stability, and is not easily deformed or damaged at high temperatures. It also possesses insulating properties, preventing the risk of electric shock. In addition, ceramic material is resistant to chemical corrosion, making it suitable for long-term contact with various skincare products.

[0105] like Figure 4 and Figure 8 As shown, the heating element 18 can be a heating wire, which can be wound around the heat-conducting base 19 to make the temperature distribution inside the heating chamber 6 more uniform. Figure 18 As shown, the heating element 18 can also be a heat-conducting rod, which is mounted on the heat-conducting base 19.

[0106] Heating process: When the heating element 18 is activated, the heat generated is first absorbed by the heat conduction seat 19, and then quickly and evenly transferred to the heating chamber 6 and the skin care products inside.

[0107] Heat preservation effect: After the heating element 18 stops working, the heat conduction base 19 can still maintain a certain temperature and continue to provide heat to the heating chamber 6, which helps to keep the skin care product in a relatively constant temperature range.

[0108] Therefore, the heating effect can be further improved by using the heat-conducting seat 19 in this embodiment, thereby improving the user experience.

[0109] In some embodiments, refer to Figure 4 and Figure 8 As shown, the heating component 7 also includes a heat-conducting structure layer 20, and the gap between the heat-conducting base 19 and the heating chamber 6 is filled with the heat-conducting structure layer 20.

[0110] Specifically, the type of thermally conductive structural layer 20 is not particularly limited. For example, it can be thermal paste, which has good flexibility and adhesion and can form an effective heat conduction path between different material surfaces. In addition to thermal paste, other types of thermally conductive structural layer 20 can be selected according to specific needs, such as thermal pads, thermal tapes, etc.

[0111] Therefore, in this embodiment of the application, the thermally conductive structure layer 20 can fill the tiny gap between the thermally conductive base 19 and the heating chamber 6, so that the thermally conductive base 19 and the heating chamber 6 can achieve a closer contact, reduce thermal resistance, and thus significantly improve the heat transfer efficiency.

[0112] In some embodiments, refer to Figure 19 As shown, the heating component 7 includes a housing 21 and a metal spring 22. The housing 21 contains a supersaturated solution (not shown in the figure), and the housing 21 covers the heating chamber 6. The metal spring 22 is disposed on the housing 21.

[0113] Specifically, the interior of the shell 21 is filled with a supersaturated solution (e.g., sodium acetate), which remains liquid and supersaturated at room temperature. A metal spring 22 is disposed on the shell 21, and a corresponding button (not shown in the figure) can be provided on the cover 1 at the position corresponding to the metal spring 22. The user can deform the metal spring 22 by pressing the button. The deformation of the metal spring 22 will trigger a crystallization process in the supersaturated solution inside the shell 21, thereby releasing a large amount of heat and achieving rapid heating, similar to the working principle of a metal hand warmer.

[0114] Therefore, the embodiments of this application can start the heating process with a simple pressing operation, realizing instant heating of skin care products and greatly facilitating user operation. Furthermore, by utilizing the exothermic crystallization properties of supersaturated solutions, energy is saved, while reducing the complexity and cost of the equipment.

[0115] In some embodiments, refer to Figures 1 to 8 As shown, the bottle body 5 is provided with a bottle mouth 8, and the cap body 1 includes an outer shell 23 and a base 24. The top of the outer shell 23 is provided with a liquid suction and discharge assembly 4, and the bottom of the outer shell 23 is provided with a connection port. The base 24 is connected to the connection port and is used to surround and connect to the bottle mouth 8. The heating assembly 2 is located between the outer shell 23 and the base 24, and the liquid guide tube 3 is located outside the cap body 1 and adjacent to the base 24.

[0116] Specifically, the top of the bottle body 5 has a dedicated bottle opening 8 for connecting the bottle cap, ensuring a secure seal for the skincare product and facilitating easy unscrewing and opening for storage. The outer shell 23 is the main body of the cap body 1, with a liquid suction and discharge assembly 4 installed at the top to control the intake and discharge of the skincare product. The bottom has a connection port for connecting to the base 24. The base 24 mates with the connection port at the bottom of the outer shell 23 and is connected (e.g., by a threaded connection) to the bottle opening 8, forming a closed space. The heating assembly 2 is located within this space, achieving heating while maintaining the compactness of the overall structure.

[0117] Therefore, the embodiments of this application achieve both a compact and stable structure and efficient and convenient functionality through the reasonable layout of each component.

[0118] In some embodiments, refer to Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the top of the base 24 is provided with a connecting hole 25; the bottom of the insulated box 17 is provided with an annular sealing part 26, and there is a connecting groove 27 between the sealing part 26 and the insulated box 17 that is adapted to the edge of the connecting hole 25. The edge of the connecting hole 25 is embedded in the connecting groove 27, and the sealing part 26 is sandwiched between the top of the base 24 and the end face of the bottle mouth 8.

[0119] Specifically, the annular sealing part 26 can be integrally formed on the bottom of the insulation box 17, forming a connecting groove 27 between it and the insulation box 17. The connecting groove 27 is adapted to the edge of the connecting hole 25 on the top of the base 24, so that the edge of the connecting hole 25 can be embedded in the connecting groove 27, thereby making the insulation box 17 firmly fixed on the base 24, reducing the risk of shaking or loosening during use, and enhancing the stability of the overall structure.

[0120] The sealing part 26 is sandwiched between the top of the base 24 and the end face of the bottle mouth 8, effectively filling the gap between the two to prevent skin care products from leaking or external contaminants from entering the bottle, ensuring the seal at the connection between the bottle cap and the bottle body 5. The sealing part 26 can be made of a material with good elasticity and durability, such as silicone or rubber, to ensure sealing effect and reliability during long-term use.

[0121] Therefore, through the above design, the embodiments of this application not only achieve stable fixation of the insulated box 17, but also ensure good sealing at the connection between the bottle cap and the bottle body 5.

[0122] In some embodiments, refer to Figures 1 to 4 , Figure 20 As shown, the liquid suction and discharge assembly 4 includes a pressing cap, which is located on the cover 1 and connected to the heating chamber 6.

[0123] Specifically, the top of the outer casing 23 is provided with a mounting hole 28, and the bottom of the press cap is provided with a mounting part 29. The mounting part 29 is installed in the mounting hole 28, thereby fixing the press cap. Figure 4 As shown, the press cap can be a dropper cap. (As shown) Figure 20 As shown, the press cap can also be an elastic telescopic cap.

[0124] When a user needs to heat skincare products, they simply press the cap, creating negative pressure that draws the product from the bottle 5 into the heating chamber 6 via the liquid guide tube 3. At this time, the cap acts like a pump, ensuring the product smoothly enters the heating chamber 6 to await heating. After heating is complete, the user presses the cap again, pushing the product out of the heating chamber 6 through the liquid guide tube 3 for use.

[0125] Therefore, the embodiments of this application can complete the extraction and discharge of skin care products with a simple pressing action, without complicated operations, which greatly simplifies the usage process and improves the user experience.

[0126] In some embodiments, refer to Figures 5 to 8 As shown, the liquid suction and discharge assembly 4 includes a push-pull rod 30 and a piston 31. The piston 31 is slidably connected inside the heating chamber 6, and the push-pull rod 30 is connected to the piston 31 and exposed on the cover 1.

[0127] Specifically, the top of the outer shell 23 is provided with a mounting hole 28, and a mounting part 29 is provided inside the mounting hole 28. The push-pull rod 30 passes through the mounting part 29 to guide and limit the push-pull rod 30. The mounting part 29 is sealed and connected to the top of the heating chamber 6 to fix the heating chamber 6.

[0128] When a user needs to heat a skincare product, pulling the push-pull rod 30 outward causes the piston 31 to move backward, creating negative pressure within the heating chamber 6. This negative pressure draws the skincare product from the bottle 5 into the heating chamber 6 through the liquid guide tube 3. At this time, the push-pull rod 30 acts similarly to a syringe, ensuring precise extraction of the desired skincare product. After heating is complete, the user pushes the push-pull rod 30 inward, causing the piston 31 to move forward and eject the heated skincare product through the liquid guide tube 3 for user use.

[0129] Therefore, the push-pull rod 30 design in this embodiment can reduce the difficulty of operation for users and accurately control the amount of skin care products dispensed.

[0130] In some embodiments, refer to Figures 21 to 25 As shown, the bottle body 5 has a bottle mouth 8, the cap 1 includes an outer shell 23 and a base 24, the outer shell 23 is slidably sleeved on the base 24, the top of the outer shell 23 is provided with an installation port, the base 24 is used to surround and connect to the bottle mouth 8, the heating component 2 is located between the outer shell 23 and the base 24, and the liquid guide tube 3 passes through the base 24; the heating chamber 6 includes an end plate 32 that covers the installation port, the end plate 32 is provided with a liquid outlet hole 33 that communicates with the heating chamber 6; the liquid suction and discharge component 4 includes a liquid outlet pump 34, the liquid outlet pump 34 is located inside the liquid guide tube 3 and is connected to the heating chamber 6.

[0131] Specifically, the bottle body 5 has a dedicated bottle opening 8 at its top for connecting the cap 1, ensuring the overall sealing and stability of the device. The outer shell 23 is slidably fitted onto the base 24, allowing it to move up and down within a certain range. The base 24 is connected (e.g., threaded) to the bottle opening 8, forming a closed space to ensure the safe sealing of the skincare product. The top of the outer shell 23 has an installation port for installing the end plate 32 of the heating chamber 6. The heating assembly 2 is located within the space enclosed by the outer shell 23 and the base 24, including the heating chamber 6 and its related heating components 7, achieving the heating function while maintaining the compactness of the overall structure. The liquid guide tube 3 passes through the base 24 to connect the heating chamber 6 and the bottle body 5, guiding the skincare product into and out of the heating chamber 6.

[0132] The liquid suction and discharge assembly 4 includes a liquid discharge pump 34. The working principle of the liquid discharge pump 34 is similar to that of a shampoo pump. The skin care product is extracted and discharged through a pressing action. The process is roughly as follows: the user presses the outer shell 23, which moves the heating chamber 6 downward, triggering the liquid discharge pump 34 in the liquid guide tube 3 to work. The skin care product is drawn from the bottle 5 into the heating chamber 6 through the liquid guide tube 3 for heating, and can be discharged through the liquid discharge hole 33 for the user to use.

[0133] Therefore, through the above design, the skincare products inside the bottle 5 can be introduced into the bottle cap for heating, avoiding repeated heating of the entire bottle of skincare products, improving the efficiency and effectiveness of skincare product use, and ensuring that the product quality is not damaged. Furthermore, the instant heating function ensures an optimal skincare experience every time it is used.

[0134] In some embodiments, refer to Figure 23 and Figure 24 As shown, the end plate 32 includes a first flange 35 that is arranged around the heating chamber 6. The side edge of the first flange 35 is connected to the edge of the mounting port. The first flange 35 is light-transmitting. The bottle cap also includes a phototherapy component 36 disposed in the cap body 1. The phototherapy component 36 includes a phototherapy lamp plate 37 that is arranged around the heating chamber 6 and corresponds to the first flange 35. The phototherapy lamp plate 37 includes lamp beads 38 facing the first flange 35. The lamp beads 38 are used to indicate the heating status of the heating component 7 or for phototherapy.

[0135] Specifically, the first flange 35 of the end plate 32 is light-transmitting to ensure that light can pass through smoothly. Of course, the entire end plate 32 or the heating chamber 6 can also be a light-transmitting component to improve the light transmission effect and facilitate processing.

[0136] The LED bead 38 can emit different colors of light according to different needs. For example, during heating, the LED bead 38 flashes green light and emits light through the first flange 35 to indicate to the user that the heating process is in progress. After heating is complete, the LED bead 38 can change to a specific color (such as red or blue light) to achieve a phototherapy effect and further enhance the skincare experience. Among them, red light helps promote blood circulation and collagen production, while blue light is used for antibacterial and anti-inflammatory purposes.

[0137] In one example, refer to Figure 25 As shown, the LED bead 38 includes a first LED bead 39 and multiple second LED beads 40 arranged in a ring around the heating chamber 6. The first LED bead 39 is used to indicate the heating status of the heating component 7 or for phototherapy, while the second LED beads 40 are used for phototherapy. During heating, the first LED bead 39 flashes green light and emits light through the first flange 35 to indicate to the user that the heating process is in progress. After heating is completed, the first LED bead 39 and the second LED beads 40 can light up together in the same color (such as red or blue light) to achieve the phototherapy effect.

[0138] Therefore, through changes in lighting, users can intuitively understand the device's working status, enhancing human-computer interaction and increasing the enjoyment and satisfaction of use. Furthermore, while providing heating for skincare products, it also adds a phototherapy effect, significantly improving the user experience and meeting the needs of different users.

[0139] In some embodiments, refer to Figures 23 to 25 As shown, the phototherapy assembly 36 also includes a light shield 41, which covers the heating chamber 6 and has a second flange 42 corresponding to the first flange 35. The second flange 42 has a light-transmitting hole 43. The phototherapy lamp plate 37 is arranged around the light shield 41 and is located on the side of the second flange 42 facing away from the first flange 35, and the lamp beads 38 are inserted into the light-transmitting hole 43. The heating component 7 is located between the heating chamber 6 and the light shield 41.

[0140] Specifically, a light shield 41 is mounted on the heating chamber 6 and has a second flange 42 corresponding to the first flange 35, which serves to fix the phototherapy lamp plate 37 and shield the light. The second flange 42 has a light-transmitting hole 43, which is used to position and support the first lamp bead 39 and the second lamp bead 40, ensuring that they are accurately aligned with the first flange 35, thereby achieving effective light transmission.

[0141] Understandably, the presence of the light shield 41 effectively prevents unnecessary light leakage, allowing the light to be concentrated in the designated area and improving the phototherapy effect. The heating element 7 can be a heating plate, sandwiched between the bottom of the heating chamber 6 and the light shield 41. This arrangement facilitates effective heat transfer while preventing the phototherapy lamp panel 37 from being affected by excessive heat, ensuring its normal operation.

[0142] Therefore, by introducing the light shield 41 and its unique structural design, this embodiment of the application not only achieves stable installation of the phototherapy lamp panel 37, but also significantly improves the phototherapy effect and enhances the safety and reliability of the product.

[0143] In some embodiments, refer to Figure 23 and Figure 24 As shown, the light shield 41 is provided with a guide tube 44 and a limiting tube 45 on the side away from the second flange 42. The guide tube 44 is slidably connected to the liquid guide tube 3. The limiting tube 45 is provided in the guide tube 44. The limiting tube 45 includes a first limiting cavity 46 and a second limiting cavity 47 that are connected. The heating chamber 6 is provided with a positioning tube 48 on the side away from the end plate 32. The positioning tube 48 is connected to the first limiting cavity 46. One end of the liquid pump 34 is connected to the second limiting cavity 47.

[0144] Specifically, the guide tube 44 is slidably connected inside the liquid guide tube 3, ensuring that the skin care products can smoothly enter and exit the heating chamber 6, while also providing a stable guide path for the up and down movement of the outer shell 23, ensuring that the user can operate smoothly and without obstruction when pressing and releasing the outer shell 23.

[0145] The limiting tube 45 is used to precisely install and fix the heating chamber 6 and the liquid pump 34, ensuring a stable position and preventing displacement during use, thereby improving the accuracy and consistency of skin care product extraction and discharge.

[0146] Therefore, the embodiments of this application not only realize the moving guidance of the outer shell 23 and the limiting installation of the heating chamber 6 and the liquid discharge pump 34, but also ensure the compactness of the structure and the reliability of the function.

[0147] In some embodiments, refer to Figures 22 to 24 As shown, the end plate 32 is provided with a ball groove 49, the wall of the ball groove 49 is provided with a liquid outlet hole 33, and the ball groove 49 is provided with balls (not shown in the figure) for massage.

[0148] Specifically, the end plate 32 is provided with at least one ball bearing groove 49, and the wall of the ball bearing groove 49 is provided with a liquid outlet hole 33, so that the skin care product can flow out smoothly by gravity when the container is tilted or inverted. The ball bearing is located in the ball bearing groove 49, so users can massage their face or skin while using skin care products, which enhances the comfort and effect of the skin care process.

[0149] When the user presses the outer casing 23, the dispensing pump 34 is activated, drawing the skincare product from the bottle 5 through the liquid guide tube 3 into the roller ball groove 49, ready for the user to use. During use, the user can tilt or invert the container to allow the skincare product to flow out through the dispensing hole 33 on the roller ball groove 49 using gravity. Furthermore, the user can massage the product by rolling the roller ball while applying it. The roller ball design not only promotes the absorption of the skincare product but also enhances blood circulation, improving the skincare effect.

[0150] Therefore, the embodiments of this application not only realize the heating and phototherapy functions of skin care products, but also add a massage effect, which can meet a variety of user needs and significantly improve the user's skin care experience.

[0151] In some embodiments, refer to Figure 21 As shown, the bottle cap also includes a cap 50, which is fitted onto the cap body 1.

[0152] Specifically, when the user needs skincare, simply remove the cap 50 to expose the ball bearing and other structures on the top of the cap 1 to perform the skincare procedure. When not in use, replace the cap 50 on the cap 1 to ensure the cap is sealed and protects the internal components from external environmental influences.

[0153] Therefore, by introducing the design of the cap 50 in this embodiment, not only is the bottle cap easy to operate when in use, but it also provides sealing protection when not in use, ensuring safety and hygiene.

[0156] Specifically, the mounting hole 52 on the mounting part 29 is used to install and fix the power management module 55. The top of the housing 23 is provided with a positioning hole 53 that corresponds to and communicates with the mounting hole 52, ensuring that the power management module 55 can be accurately aligned and exposed on the surface of the housing 23, so as to facilitate the user pressing the button 57 and charging operation. The integrated design of the power management module 55 combines the button 57 and the charging component 58 into one, saving space and making the overall structure more compact. The charging component 58 can be a charging head, charging interface, charging electrodes, or other structural components.

[0157] Battery 54 provides power to the entire device, and circuit board 56 is fixed to base 24 by bracket 59, responsible for coordinating and controlling the operation of various functional modules.
