[0037] Example 1:

[0038] This embodiment relates to an applicator for connecting to a tube- or bottle-packaged liquid skincare product or medicine kit, such as... Figure 1-12As shown, the applicator of this application includes an applicator body 10, a cap 94, a stimulation element 31, and a control circuit board 4. The applicator body 10 is provided with a liquid outlet 111, a liquid inlet 120, and a liquid guiding channel 50 connecting the liquid outlet 111 and the liquid inlet 120. A positioning part 112 is protruding from the outer surface of the applicator body 10, and the positioning part 112 is conductive. The cap 94 covers the end of the applicator body 10 where the liquid outlet 111 is located, and the opening edge of the cap 94 has a positioning notch for the positioning part 112 to be inserted into. The stimulation element 31 is disposed on the applicator body 10 and is used to stimulate the user's skin. The stimulation element 31 includes one or more of a microcurrent element, a phototherapy lamp, a heating element, a cooling element, and a vibration element. The control circuit board 4 is disposed inside the applicator body 10 and is electrically connected to the positioning part 112 and the stimulation element 31, respectively. The positioning part 112 is used to activate the stimulation element 31. When a user's finger is placed on the positioning part 112, the positioning part 112 activates the stimulation element 31, so that the stimulation element 31 can provide stimulation therapy to the user's skin. Figure 1 and Figure 4 As shown, the positioning notch on the cap 94 engages with the positioning part 112 to prevent the cap 94 from rotating relative to the applicator body 10 when it is closed, thus reducing friction between the cap 94 and the applicator body 10. Simultaneously, when the cap 94 is open to use the applicator body 10, the user can hold the applicator body 10 with their thumb resting on the positioning part 112. The design of the positioning part 112 allows for a better grip on the applicator body 10, conforming to ergonomics. The positioning part 112 can be circular, elliptical, rectangular, or other shapes.

[0039] In this embodiment, the stimulating element 31 is a conductive element and is exposed outside the applicator body 10, located near the liquid outlet 111. The pair of microcurrent electrodes formed by the stimulating element 31 and the positioning part 112 come into contact with the skin to generate a microcurrent that stimulates the skin, thereby enhancing the skin's absorption of skincare products or medicines. Preferably, to facilitate the user's application of skincare products or operation, the side of the applicator body 10 with the liquid outlet 111 is angled relative to the outer shell 1, making the user's operation more effortless and more ergonomic.

[0040] It should be noted that a pair of microcurrent electrodes are electrically connected to the control circuit board 4, which has an electric pulse massage circuit. The pair of microcurrent electrodes are connected to the electric pulse massage circuit, so that the microcurrent electrodes can be used to contact the skin and use pulse current for physiotherapy / massage, which increases the functionality of the applicator.

[0041] In other embodiments, the stimulation element 31 is one or more combinations of elements such as a phototherapy lamp, a heating element, a cooling element, and a vibration element, wherein the phototherapy lamp is a light-emitting diode or a laser. In this embodiment, the positioning part 112 has a conductive capacitive touch switch electrically connected to the control circuit board 4, or the positioning part 112 is provided with a capacitive touch switch electrically connected to the control circuit board 4 to make the positioning part 112 conductive. When the user's finger is placed on the positioning part 112, the capacitive touch switch activates the stimulation element 31, and the stimulation element 31, such as a phototherapy lamp, a heating element, a cooling element, or a vibration element, works to provide light stimulation, heat stimulation, cold stimulation, or vibration massage stimulation to the skin.

[0042] In some embodiments, to enable a user to place their finger on the positioning part 112 to use the applicator body 10, when one end of the applicator body 10 with a liquid outlet 111 contacts the skin, a microcurrent is generated to stimulate the skin, such as... Figure 1-4 As shown in Figures 10-12, the applicator body 10 includes a housing 1, a control circuit board 4 disposed inside the housing 1, and liquid outlet 111 and liquid inlet 120 respectively disposed at both ends of the housing 1. The housing 1 is made of insulating material. A stimulating element 31 is embedded in the housing 1 at one end with the liquid outlet 111. Optionally, the stimulating element 31 is a conductive material layer plated on the housing 1 at one end with the liquid outlet 111. The positioning part 112 is integrally formed with the housing 1, and a conductive layer 32 is embedded or plated on the outer surface of the positioning part 112 to make the positioning part 112 conductive. Optionally, the positioning part 112 is made of conductive material and embedded in the side wall of the housing 1. In this embodiment, the housing 1 can be made of non-conductive lightweight materials such as plastic, rubber, or silicone. The conductive layer 32 and the stimulation element 31 can be made of conductive metal products. The conductive layer 32 and the conductive material layer can be metal layers with good conductivity, such as gold plating, silver plating, or copper plating. The conductive layer 32 embedded on the positioning part 112 can be made of metal sheets, such as aluminum sheets, copper sheets, silver sheets, or other metal sheets or metal parts with good conductivity.

[0043] Furthermore, to facilitate the assembly of the control circuit board 4 into the housing 1, such as... Figure 1-4As shown in Figures 10-12, the outer casing 1 includes: a first casing 11, on which the stimulating element 31 and the liquid outlet 111 are both disposed; and a second casing 12, which is fixedly fitted to the first casing 11 to form a mounting cavity 100, in which the control circuit board 4 is located; a liquid inlet 120 is located on the second casing 12 away from the liquid outlet 111; and a positioning part 112 is located on the outer wall of either the first casing 11 or the second casing 12. A portion of the liquid guiding channel 50 is disposed in the first casing 11 and the other portion in the second casing 12. When using the applicator body, the user can hold the second casing 12 below the positioning part 112, and then place their thumb on the positioning part 112. When the stimulating element 31 contacts the user's skin, the positioning part 112 and the stimulating element 31 conduct to generate a microcurrent to promote the absorption of the skincare product by the user's skin.

[0044] In some embodiments, such as Figure 1-4 As shown in Figures 10-12, in order to make the applicator look flatter and more aesthetically pleasing when the first housing 11 and the second housing 12 are assembled, the positioning part 112 is located on the outer wall of the first housing 11 near the end of the second housing 12. The positioning part 112 extends to one side of the second housing 12, and the outer wall of the second housing 12 is provided with a relief groove 121 for the positioning part 112 to be inserted.

[0045] In some embodiments, such as Figure 3-4 As shown in Figure 5-9, a first insertion groove 114 is formed on the inner side of the positioning part 112 on the first housing 11. A first insertion part 124 protrudes from one end of the second housing 11 near the first housing 11 and inserts into the first insertion groove 114. The first insertion part 124 protrudes outward from the edge of the clearance groove. A second insertion groove 113 is formed on the side of the first housing 11 away from the liquid outlet 111. A second insertion part 123 protrudes from one end of the second housing 12 near the first housing 11 and inserts into the second insertion groove 113. Both the second insertion groove 113 and the second insertion part 123 are annular, but not limited to annular. The second insertion part 123 and the second insertion groove 113 are interference-fitted. Preferably, the insertion groove is annular, the first insertion groove 114 and the second insertion groove 113 are connected, and the depth of the first insertion groove 114 is greater than the depth of the second insertion groove 113.

[0046] In some embodiments, such as Figure 3 , 4The applicator body 10 also includes a liquid guiding component 5, which is disposed within the outer shell 1. A liquid guiding channel 50 passes through the liquid guiding component 5 and connects its two ends to an outlet hole 111 and an inlet hole 120. In this embodiment, the liquid guiding component 5 includes a first conduit 51 and a second conduit 52. The first conduit 51 extends from the outlet hole 111 into the interior of the outer shell 1. One end of the second conduit 52 is connected to the end of the first conduit 51 away from the outlet hole 111, and the other end of the second conduit 52 is connected to the inlet hole 120. Specifically, the first conduit 51 and the second conduit 52 are provided with a sealing sleeve 53 connecting the first conduit 51 and the second conduit 52. The sealing sleeve 53 has a first connecting cavity and a second connecting cavity for the first conduit 51 and the second conduit 52 to be inserted into, respectively. The first connecting cavity communicates with the second connecting cavity, and the first connecting cavity is sealed to one end of the first conduit 51, and the second conduit 52 is sealed to one end of the second connecting cavity. In other embodiments, the first conduit 51 can be inserted into the second conduit 52, and a sealing ring is provided at the insertion point of the first conduit 51 and the second conduit 52. The design of the sealing ring or sealing sleeve 53 reduces the risk of leakage in the liquid channel 50 formed by the first conduit 51 and the second conduit 52, thereby improving product reliability and user experience.

[0047] In some embodiments, to facilitate the processing and assembly of the applicator's components while ensuring a compact structure, such as... Figure 3-9 The housing 1 shown also includes a first fixing frame 6. A mounting surface 60 is formed at one end of the first fixing frame 6 near the liquid outlet 111, and a limiting part 61 is provided on the mounting surface 60. The stimulation element 31 also includes a phototherapy component 7, which includes a lamp plate 70 and a light-transmitting plate 71. The lamp plate 70 is disposed on the mounting surface 60 and inserted into the limiting part 61. A first conduit 51 passes through the lamp plate 70 and communicates with a second conduit 52. The light-transmitting plate 71 is embedded on the first end face and is disposed opposite to the lamp plate 70. At least one light-emitting element is provided on the lamp plate 70, and the light emitted by the light-emitting element is emitted outward toward the light-transmitting plate 71 for phototherapy by the user. In this embodiment, a conductive element is embedded in the light-transmitting plate 71 or disposed on the first housing 11 near the liquid outlet 111 and located outside the light-transmitting plate 71. In this embodiment, the lamp plate 70 is provided with a first limiting hole 701 that is inserted into the limiting part 61, so that the lamp plate 70 is stably fixed on the mounting surface 60. In some embodiments, in order to limit and fix the light-emitting body on the lamp plate 70 and at the same time make the light emitted by the light-emitting body more concentrated, the phototherapy assembly 7 also includes a positioning plate 72. The positioning plate 72 is provided with a through hole 721 for the light-emitting body on the lamp plate 70 to be inserted, and the positioning plate 72 is also provided with a second limiting hole 722 that is inserted into the limiting part 61.

[0048] In other embodiments, a mounting groove is provided on the side of the first housing 11 near the liquid outlet 111, and at least one through hole 721 communicating with the mounting groove is provided at the bottom of the mounting groove. The applicator also includes a phototherapy component 7, which includes a lamp plate 70 and a light-transmitting plate 71. The lamp plate 70 is disposed inside the first housing 11, and the light-emitting element on the lamp plate 70 is inserted into the through hole 721. The light-transmitting plate 71 covers the mounting groove, and the side of the light-transmitting plate 71 away from the lamp plate 70 is flush with the end face of the first housing 11 near the liquid outlet 111.

[0049] It should be noted that the light emitted by the light-emitting element is projected outward through the light-transmitting part to irradiate the skin for a cosmetic effect. The light panel 70 can emit one or more of the following: red light, blue light, purple light, or other light sources. Different types of light-emitting elements can be set as needed. The light-emitting elements are LED beads or nano-beads. By setting the light panel 70 and the light-transmitting plate 71 on the applicator, the applicator has a phototherapy function, further increasing its functionality and enhancing the user experience.

[0050] In some embodiments, such as Figure 1-4 As shown in Figure 12, the applicator also includes a rechargeable battery 90, a charging connector, a vibration motor 2, and a push-button switch 93.
