Description

Technical Field

[0001] This utility model relates to the field of dropper bottle technology, specifically to a dropper bottle cap and a dropper container. Background Technology

[0002] There are many ways to take out cosmetics, including pouring directly, spraying, squeezing, etc. Skin care products such as serums or essential oils are often taken out using droppers due to their usage and high price. Dropper bottles expel air from the rubber nozzle by squeezing it. After releasing the nozzle, the liquid in the bottle will be drawn into the dropper due to the pressure difference between atmospheric pressure and the dropper. Dropper bottles have a simple structure and are easy to carry, making them increasingly widely used.

[0003] With the continuous improvement and development of living standards, users usually use droppers to draw up skin care products and then apply them to the skin. In order to promote the absorption of skin care products or to perform physical and cosmetic treatments on the skin, users usually need to use a beauty device after applying cosmetics. However, beauty devices are usually separate instruments, and it is usually necessary to take out the beauty device and dropper from different places, which makes the skin care operation inconvenient. Utility Model Content

[0004] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a dropper cap and dropper container that retains the function of pressing and dispensing liquid in a press-type dropper container while integrating the function of a physiotherapy device. This eliminates the inconvenience of having to use a dropper and a beauty device separately in traditional skincare, thus solving the problem of inconvenient operation or use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a dropper cap, comprising: a connecting shell for detachable connection with an external container, wherein the connecting shell has a movable cavity; a dropper structure for absorbing skincare products from the container, the dropper structure including a pressing airbag assembly and a suction tube, the pressing airbag assembly being movably confined within the movable cavity, the pressing airbag assembly having an elastic airbag, and the suction tube for connecting the elastic airbag to the container; and a physiotherapy device for performing physiotherapy on the skin, the physiotherapy device being movably disposed in the movable cavity, the physiotherapy device being able to move relative to the connecting shell and squeeze the pressing airbag assembly under external force to compress the elastic airbag; when the physiotherapy device removes its squeezing action on the pressing airbag assembly, the elastic airbag recovers its elastic deformation under its own elasticity so that the suction tube can absorb the skincare products from the container.

[0006] Preferably, the dropper cap further includes an elastic element disposed within the movable cavity; one end of the elastic element abuts against the pressure airbag assembly, and the other end abuts against the cavity wall of the movable cavity. When the physiotherapy device squeezes the pressure airbag assembly, the pressure airbag assembly compresses the elastic element. When the physiotherapy device removes its squeezing action on the pressure airbag assembly, the elastic element provides a restoring force for the reset of the elastic airbag of the pressure airbag assembly. Alternatively, one end of the elastic element abuts against the physiotherapy device, and the other end abuts against the cavity wall of the movable cavity. When the physiotherapy device squeezes the pressure airbag assembly, the physiotherapy device compresses the elastic element. When the physiotherapy device removes its squeezing action on the pressure airbag assembly, the elastic element provides a restoring force for the reset of the physiotherapy device.

[0007] Preferably, the physiotherapy device is detachably connected to the airbag assembly, and the connecting shell is detachably connected to the physiotherapy device.

[0008] Preferably, the airbag assembly further includes a baffle, which is disposed between the elastic airbag and the physiotherapy device, and the elastic airbag is fixed to the side of the baffle away from the physiotherapy device; the physiotherapy device can move relative to the connecting shell and squeeze the baffle under the action of external force, so that the baffle compresses the elastic airbag.

[0009] Preferably, the physiotherapy device is provided with a first sidewall facing the baffle; the first sidewall is provided with a first magnetic element, and the baffle is provided with a second magnetic element that is magnetically attracted and fixed to the first magnetic element; and / or, the first sidewall is provided with a physiotherapy unit, the physiotherapy unit being used to stimulate the skin to perform physiotherapy on the skin.

[0010] Preferably, at least a portion of the physiotherapy unit protrudes outward from the first sidewall, and the baffle is provided with a clearance groove facing the physiotherapy unit, with the physiotherapy unit and the groove wall of the clearance groove being spaced apart.

[0011] Preferably, the physiotherapy device is movable relative to the active cavity along a first direction to squeeze or move away from the baffle; the active cavity has a first limiting part on its cavity wall, the first limiting part extends along a second direction, the second direction being perpendicular to the first direction; the baffle has a second limiting part on its outer side wall, the projections of the first limiting part and the second limiting part in the first direction overlap, and the first limiting part is closer to the physiotherapy device than the second limiting part.

[0012] Preferably, a third limiting part is further provided on the outer side wall of the baffle. The third limiting part can slide relative to the first limiting part along the first direction. The third limiting part and the first limiting part are in concave-convex cooperation to restrict the rotation of the baffle relative to the connecting shell.

[0013] Preferably, the active cavity has an opening communicating with the outside, and the physiotherapy device includes a housing and a physiotherapy unit. The physiotherapy unit is used to stimulate the skin to perform physiotherapy on the skin. The housing includes an insertion part and a gripping part. The insertion part is inserted into the active cavity and can slide along the active cavity. The physiotherapy unit is disposed on the insertion part. The gripping part is fixed to the side of the insertion part away from the pressing airbag assembly. The gripping part extends out of the connecting shell through the opening.

[0014] A dropper container includes: a container and a dropper cap as described above, wherein the container and the dropper cap are detachably connected.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0016] A movable cavity is set inside the connecting cover, and the pressing airbag assembly is confined within the movable cavity. The suction tube connects the elastic airbag and the container, realizing the basic function of the dropper structure to absorb skincare products. Simultaneously, a physiotherapy device is installed on the connecting shell for skin treatment, integrating the functions of the dropper and the physiotherapy device. Users no longer need to remove the beauty device and dropper from separate places, eliminating the inconvenience of separately using the dropper and beauty device in traditional skincare, thus improving the convenience of skincare operations. Under external force, the physiotherapy device can move relative to the connecting shell and squeeze the pressing airbag assembly to compress the elastic airbag. When the physiotherapy device releases the pressure on the pressing airbag assembly, the elastic airbag recovers its elastic deformation under its own elasticity, allowing the suction tube to absorb the skincare products in the container. This allows for direct squeezing of the pressing airbag assembly by the physiotherapy device to absorb skincare products, achieving linkage between liquid extraction and the physiotherapy device, making operation simple.

[0035] Example 1:

[0036] This embodiment relates to a dropper bottle cap, such as... Figures 1-5 , Figure 8 As shown, it includes a connecting shell 1, a dropper structure 2, and a physiotherapy device 3.

[0037] The connecting shell 1 is used for detachable connection with the external container 4, and the connecting shell 1 has a movable cavity 10. Optionally, the connecting shell 1 and the container 4 can be detachably assembled by means of threaded connection or snap-fit ​​connection. The dropper structure 2 is used to draw skin care products from the container 4, such as fluid serums or essential oils. The dropper structure 2 includes a pressing airbag assembly 21 and a suction tube 22. The pressing airbag assembly 21 is movably confined within the movable cavity 10 and has an elastic airbag 210. The suction tube 22 connects the elastic airbag 210 and the container 4. The elastic airbag 210 can be compressed and deformed under force, and the air inside the elastic airbag 210 is squeezed out through the suction tube 22. After the pressure on the elastic airbag 210 is released, the elastic airbag 210 returns to its original position, making the air pressure inside the elastic airbag 210 less than atmospheric pressure. Under the action of negative pressure, the skin care products in the container 4 are drawn into the suction tube 22, thereby realizing the absorption of skin care products. The physiotherapy device 3 is used to perform physiotherapy on the skin. It provides stimulation such as phototherapy, hot compresses, cold compresses, electrotherapy, or vibration massage to achieve the physiotherapy function. The physiotherapy device 3 is located in the movable cavity 10. Under external force, the physiotherapy device 3 can move relative to the connecting shell 1 and squeeze and press the airbag assembly 21 to compress the elastic airbag 210. For example... Figure 8 , Figure 9 As shown, when the physiotherapy device 3 removes the squeezing action on the airbag assembly 21, the elastic airbag 210 recovers its elastic deformation under its own elasticity so that the suction tube 22 can draw up the skin care product in the container 4.

[0038] Optionally, the physiotherapy device 3 abuts against the pressure airbag assembly 21, and the physiotherapy device 3 is slidably assembled in the movable cavity 10 and magnetically fixed to the pressure airbag assembly 21; or the physiotherapy device 3 and the movable cavity 10 are connected by threads to achieve abutment to compress the pressure airbag assembly 21; in other embodiments, the physiotherapy device 3 is slidably assembled in the movable cavity 10 and fixedly connected to the pressure airbag assembly 21, and the physiotherapy device 3 can be fixedly connected to the pressure airbag assembly 21 by adhesive, hot injection molding, glue welding or other fixing methods. In this embodiment, the physiotherapy unit 33 at one end of the physiotherapy device 3 is located outside the movable cavity 10, and the other end is fixedly connected to the pressure airbag assembly 21 by adhesive, hot injection molding, glue welding or other fixing methods. This ensures that the physiotherapy device 3 presses on the pressure airbag assembly 21 while ensuring the physiotherapy function of the physiotherapy unit 33 on the skin.

[0039] In this embodiment, the physiotherapy device 3 can be movably connected to the connecting shell 1 via a threaded drive; for example, the outer wall of the physiotherapy device 3 is provided with an insert block, and the cavity wall of the movable cavity 10 is provided with a guide slot, the insert block and the slot engaging in a concave-convex fit, allowing the physiotherapy device 3 to be movably positioned within the movable cavity 10 along the guide slot. For another example, the dropper cap is also provided with a linear motor, which is connected to the physiotherapy device 3 via a drive mechanism. The linear motor drives the physiotherapy device 3 to move relative to the connecting shell 1 and compress the airbag assembly 21.

[0040] In this embodiment, the physiotherapy device 3 can directly squeeze and press the elastic airbag 210 in the airbag assembly 21, or it can indirectly squeeze and press the elastic airbag 210 in the airbag assembly 21. This is not limited here.

[0041] In some embodiments, such as Figure 4 , Figure 5 , Figure 8 As shown, the dropper cap also includes an elastic element 211, which is disposed within the movable cavity 10. One end of the elastic element 211 abuts against the pressing airbag assembly 21, and the other end abuts against the cavity wall of the movable cavity 10. Optionally, the elastic element 211 can be a spring, a spring sheet, or a spring block, etc. Optionally, the elastic element 211 is sleeved outside the elastic airbag 210, or multiple elastic elements 211 are provided, and multiple elastic elements 211 are distributed circumferentially around the elastic airbag 210. In other embodiments, the elastic element 211 is disposed within the cavity of the elastic airbag 210. The elastic element 211 can provide stable elastic support for the reset of the pressing airbag assembly 21, ensuring that the airbag assembly can quickly and accurately return to the initial position after pressing, thereby ensuring the normal liquid suction and dispensing functions of the dropper.

[0042] It should be noted that when the physiotherapy device 3 squeezes the airbag assembly 21, the airbag assembly 21 compresses the elastic element 211, and the elastic element 211 is compressed or deformed to store elastic potential energy; when the physiotherapy device 3 removes the squeezing action on the airbag assembly 21, the elastic element 211 is used to provide a restoring force for the reset of the elastic airbag 210 of the airbag assembly 21, so that a negative pressure is formed inside the airbag assembly 21, which facilitates the liquid to be drawn into the suction tube 22.

[0043] In some embodiments, such as Figure 4 , Figure 5 , Figure 8 As shown, one end of the elastic element 211 abuts against the physiotherapy device 3, and the other end abuts against the cavity wall of the movable cavity 10. When the physiotherapy device 3 squeezes and presses the airbag assembly 21, the physiotherapy device 3 compresses the elastic element 211. When the physiotherapy device 3 removes its squeezing action on the airbag assembly 21, the elastic element 211 provides a restoring force for the physiotherapy device 3 to reset. In this embodiment, the physiotherapy device 3 is slidably assembled in the movable cavity 10, and the elastic element 211 provides a restoring force for the physiotherapy device 3 to reset, reducing the risk that the elastic airbag 210 may be difficult to reset due to the gravity of the physiotherapy device 3.

[0044] In some embodiments, such as Figures 2-5 , Figure 8 As shown, the physiotherapy device 3 is detachably connected to the airbag assembly 21, and the connecting shell 1 is detachably connected to the physiotherapy device 3, so that the physiotherapy device 3 can be removed from the connecting shell 1 and the airbag assembly 22 for use or cleaning. Optionally, the physiotherapy device 3 and the airbag assembly 21 can be detachably connected via a magnetic structure, a threaded structure, or a snap-fit ​​structure. The physiotherapy device 3 and the connecting shell 1 can also be detachably connected via a magnetic structure, a threaded structure, or a snap-fit ​​structure.

[0045] In some embodiments, such as Figures 2-5 , Figures 8-9 As shown, the airbag assembly 21 also includes a baffle 212, which is disposed between the elastic airbag 210 and the physiotherapy device 3. The elastic airbag 210 is fixed to the side of the baffle 212 opposite to the physiotherapy device 3. Under external force, the physiotherapy device 3 can move relative to the connecting shell 1 and squeeze the baffle 212, so that the baffle 212 compresses the elastic airbag 210. The baffle 212 makes the squeezing force of the physiotherapy device 3 on the elastic airbag 210 more uniform. Optionally, the baffle 212 and the elastic airbag 210 are integrally set by means of adhesive or hot injection molding. In other embodiments, the baffle 212 abuts against the elastic airbag 210. In this embodiment, the physiotherapy device 3 does not directly contact the elastic airbag 210 under external force, which can reduce the impact and repeated friction on the elastic airbag 210 during the movement of the physiotherapy device 3, and reduce the risk of damage to the elastic airbag 210.

[0046] In some embodiments, such as Figure 2 , Figure 3 As shown, to achieve detachable assembly between the physiotherapy device 3 and the airbag assembly 21, the physiotherapy device 3 is provided with a first sidewall 31 facing the baffle 212. The first sidewall 31 is provided with a first magnetic element 32, and the baffle 212 is provided with a second magnetic element 213 that is magnetically attracted and fixed to the first magnetic element 32. The physiotherapy device 3 and the baffle 212 are fixed by magnetic attraction, enabling the physiotherapy device 3 to be quickly fixed to the baffle 212, and also facilitating quick disassembly between the physiotherapy device 3 and the baffle 212. Disassembly can be achieved by simply pulling the physiotherapy device 3 away from the baffle 212. One of the first magnetic element 32 and the second magnetic element 213 is a magnet, and the other is a metal element, which can be an alloy or metal containing iron, cobalt, nickel, gadolinium, etc. In other embodiments, both the first magnetic element 32 and the second magnetic element 213 are magnets.

[0047] In some embodiments, such as Figure 3 , Figure 6 , Figure 9 As shown, a physiotherapy unit 33 is provided on the first sidewall 31. The physiotherapy unit 33 is used to stimulate the skin for physiotherapy. By placing the physiotherapy unit 33 on the first sidewall 31, when the physiotherapy device 3 is not being used for skin physiotherapy, it can be stored in the movable cavity 10, while the first sidewall 31 abuts against the baffle 212. In this way, the physiotherapy unit 33 can be hidden in the movable cavity 10, which protects the physiotherapy unit 33 and reduces the risk of contamination from dust and other foreign objects due to exposure. The physiotherapy unit 33 can be one or more combinations of phototherapy lamps, microcurrent electrodes 334, hot compresses, cold compresses, radio frequency electrodes, and vibrators.

[0048] In some embodiments, such as Figure 3 , Figure 6 , Figure 9 As shown, a light-transmitting area 3310 is provided on the first sidewall 31. The physiotherapy unit 33 includes a first circuit board 333 and a phototherapy lamp bead 341. The first circuit board 333 is disposed inside the physiotherapy device 3 and adjacent to the light-transmitting area 3310. The phototherapy lamp bead 341 is integrated into the side of the first circuit board 333 facing the light-transmitting area 3310. The arrangement of the phototherapy lamp bead 341 enables the physiotherapy device 3 to perform phototherapy on the skin.

[0049] It should be noted that the phototherapy lamp bead 341 can emit one or more wavelengths of light selected from 415nm blue light, 630nm red light, 850nm near-infrared light, 560nm green light, 610nm orange light, and 290nm-400nm ultraviolet light. The phototherapy lamp 283 can be one or more selected from LEDs, lasers, fluorescent lamp beads, halogen lamps, electrodeless lamps, and xenon arc lamps, preferably LEDs and / or lasers.

[0050] In some embodiments, such as Figure 3 , Figure 6 , Figure 9 As shown, to enhance the functionality of the physiotherapy device 3, the physiotherapy unit 33 further includes a microcurrent electrode 334. The microcurrent electrode 334 is disposed inside the physiotherapy device 3 and is partially exposed on the surface of the first sidewall 31. At least two microcurrent electrodes 334 are provided, enabling the physiotherapy device 3 to perform both phototherapy and electrotherapy on the skin, thereby increasing the functionality of the physiotherapy device 3.

[0051] In some embodiments, such as Figure 3 , Figure 6 , Figure 9 As shown, the microcurrent electrode 334 is a magnetic metal electrode, which can act as the first magnetic element 32 that is magnetically attracted by the second magnetic element 213. This makes full use of the space of the first sidewall 31, making the structure of the physiotherapy device 3 more compact. At the same time, the microcurrent electrode 334 acts as the first magnetic element 32, reducing the cost of the physiotherapy device 3.

[0052] In some embodiments, such as Figure 3 , Figure 6 , Figure 9 As shown, to further enhance the functionality of the physiotherapy device 3, the physiotherapy unit 33 also includes a heat-conducting element 335 and a heating element 336. The heat-conducting element 335 protrudes from the first sidewall 31 for contact with the skin, and the heating element 336 is disposed within the physiotherapy device 3 and adjacent to the first sidewall 31. The heating element 336 is used to heat the heat-conducting element 335. The arrangement of the heat-conducting element 335 and the heating element enables the physiotherapy device 3 to have a heat therapy function. The heat-conducting element 335 is made of alloy or metal.

[0053] It should be noted that, as Figure 6 , Figure 8As shown, to ensure the normal operation of the physiotherapy device 3, the physiotherapy device 3 also includes electronic control components such as a main control board 337, a control switch 338, a battery 339, and a charger 340. The main control board 337 and battery 339 are both fixed inside the physiotherapy device 3. The control switch 338 is located on the side of the physiotherapy device 3 away from the first sidewall 31. The battery 339, control switch 338, charger 340, and physiotherapy unit 33 (first circuit board 333, heating element 336, and microcurrent electrode 334) are all electrically connected to the main control board 337. The main control board 337 is the control core of the physiotherapy device 3. The battery 339 supplies power to the electronic control components of the physiotherapy device 3, and the control switch 338 controls the operation of the physiotherapy unit 33. The control switch 338 can be a push switch or a touch switch. The charger 340 has a Type-C interface, a Lightning interface, a Micro-USB interface, and metal charging electrodes. In some embodiments, the control switch 338 is a push switch, and the charger 340 is a metal charging electrode embedded in the push switch.

[0054] In some embodiments, such as Figures 2-4 As shown, at least a portion of the physiotherapy unit 33 protrudes outward from the first sidewall 31 to ensure full contact between the physiotherapy unit 33 and the skin when the physiotherapy device 3 is used to treat the skin. The baffle 212 is provided with a clearance groove 2120 facing the physiotherapy unit 33. The physiotherapy unit 33 and the groove wall of the clearance groove 2120 are spaced apart, allowing the physiotherapy unit 33 to be inserted into the clearance groove 2120. Specifically, along the radial direction of the clearance groove 2120, the length of the clearance groove 2120 is greater than the length of the physiotherapy unit 33; along the axial direction of the clearance groove 2120, the length of the clearance groove 2120 is greater than the length of the portion of the physiotherapy unit 33 protruding from the first sidewall 31. The clearance groove 2120 on the baffle 212 prevents the baffle 212 from scratching the physiotherapy unit 33 during the process of the physiotherapy device 3 pressing against the baffle 212.

[0055] In some embodiments, such as Figure 4 , Figure 8 , Figure 9 As shown, the physiotherapy device 3 can move relative to the movable cavity 10 along a first direction to squeeze or separate from the baffle 212. The first direction coincides with or is parallel to the axial direction of the movable cavity 10. A first limiting part 11 is provided on the cavity wall of the movable cavity 10, and the first limiting part 11 extends along a second direction, which is perpendicular to the first direction. A second limiting part 2121 is provided on the outer wall of the baffle 212. The projections of the first limiting part 11 and the second limiting part 2121 in the first direction overlap. The first limiting part 11 is closer to the physiotherapy device 3 than the second limiting part 2121. The arrangement of the first limiting part 11 and the second limiting part 2121 restricts the dropper assembly within the movable cavity 10, preventing the airbag assembly 21 from being dislodged from the movable cavity 10 under the action of magnetic force during the process of pulling out the physiotherapy device 3.

[0056] Specifically, in this embodiment, the first limiting part 11 divides the active cavity 10 into a first chamber and a second chamber that are interconnected. The physiotherapy device 3 is slidably assembled in the first chamber, and the pressure airbag assembly 21 is disposed in the second chamber. The pressure airbag assembly 21 extends into the first chamber and abuts against the physiotherapy device 3. The first limiting part 11 is used to restrict the pressure airbag assembly 21 in the second chamber.

[0057] In some embodiments, such as Figure 4 , Figure 8 , Figure 9 As shown, a third limiting part 2122 is also provided on the outer side wall of the baffle 212. The third limiting part 2122 can slide relative to the first limiting part 11 in the first direction. The third limiting part 2122 and the first limiting part 11 are in concave-convex cooperation to restrict the rotation of the baffle 212 relative to the connecting shell 1, so that the baffle 212 can move linearly back and forth under the action of the physiotherapy device 3 or the elastic element 211, which makes it easy for the physiotherapy device 3 to push the elastic airbag 210 to deform or for the elastic element 211 to push the physiotherapy device 3 and / or the elastic airbag 210 to reset, so that the suction tube 22 can absorb the skin care product.

[0058] In some embodiments, such as Figure 1 , Figure 6 , Figure 8 As shown, the active cavity 10 has an opening communicating with the outside. The physiotherapy device 3 includes a housing 330 and a physiotherapy unit 33, which is used to stimulate the skin for physiotherapy. The housing 330 includes an insertion part 331 and a gripping part 332. The insertion part 331 is inserted into the active cavity 10 and can slide along the active cavity 10. The physiotherapy unit 33 is disposed on the insertion part 331. The gripping part 332 is fixed to the side of the insertion part 331 away from the pressure airbag assembly 21. The gripping part 332 extends out of the connecting housing 1 through the opening. In this embodiment, the length of the insertion part 331 in the first direction is greater than the length of the active cavity 10, so that the physiotherapy device 3 can be inserted into the active cavity 10 to compress the pressure airbag assembly 21. The outer diameter of the gripping part 332 is greater than the inner diameter of the active cavity 10, so as to facilitate the removal of the physiotherapy device 3 and prevent the physiotherapy device 3 from being over-inserted into the active cavity 10.

[0059] Optionally, in some embodiments, such as Figure 1 , Figure 6 , Figure 8 As shown, to make the grip more comfortable for the user, the edge of the grip part 332 is provided with an arc-shaped chamfer, and the connection between the grip part 332 and the plug part is provided with an arc-shaped transition surface.

[0060] In some embodiments, such as Figure 2 , Figure 4As shown, the connecting shell 1 includes a connecting sleeve 12, a sliding sleeve 13, and a connecting rib 14. The connecting sleeve 12 is threadedly connected to the container 4; the sliding sleeve 13 is sleeved outside the connecting sleeve 12, and the movable cavity 10 is located inside the sliding sleeve 13 and on the side opposite to the container 4, forming a gap between the connecting sleeve 12 and the sliding sleeve 13; the connecting rib 14 is located in the gap and is used to connect the sliding sleeve 13 and the connecting sleeve 12. Multiple connecting ribs 14 are provided, and the multiple connecting ribs 14 are circumferentially distributed on the outside of the connecting sleeve 12. The connecting ribs 14 are used for the integral molding of the connecting sleeve 12 and the sliding sleeve 13.
