Description

Technical Field

[0001] The utility model relates to the technical field of beauty instrument heating, in particular to a heating structure and a beauty instrument. Background Technique

[0002] With the change of the pace of life and the improvement of the quality of life, people pay more and more attention to their own appearance. In order to personal image or prevent skin relaxation, people mainly use cosmetics or go to professional beauty institutions for fixed-site treatment in life. This method not only has high cost, but also cosmetics may cause side effects, and professional beauty institutions need to consume a lot of time.

[0003] Therefore, there are more and more beauty instruments on the market. Handheld beauty instruments are small and light, easy to carry, and convenient for people to use at any time.

[0004] For example, the Chinese patent document with the publication number CN218853088U discloses a skin care instrument for beauty, including a skin care instrument body. The upper part of the front side of the skin care instrument body is provided with a vibration head. The front side of the vibration head is provided with a circular groove. The front side inside the circular groove is fixedly installed with a contact surface, and the rear side inside the circular groove is fixedly installed with a heating coil. A heat conduction layer is installed between the contact surface and the heating coil, and the contact surface can be heated.

[0005] Another example is the Chinese patent document with the publication number CN212814996U, which discloses a two-in-one beauty instrument for cleaning and introducing. It includes a housing, a cleaning brush provided at one end of the housing, a first conductive member provided at the other end of the housing, a second conductive member provided on the surface of the housing, and an ion generator provided inside the housing. A heating member is provided inside the housing, and the output end of the heating member is connected to the first conductive member, so that the user can promote blood circulation of the skin by heating the skin.

[0006] The heating components in the above patent documents mainly use heating films, ceramic heaters, or heating coils. Among them, the heating coil, that is, the heating coil is also called an electric heating coil or a heating coil. It uses an electric heating alloy wire as the heating material and mica soft board (sometimes using a ceramic core) as the insulating material.

[0007] However, the common feature of these materials is that they need to be directly connected to the circuit to generate heat. Therefore, the waterproof requirement for the device is also higher, and the device is easily damaged due to waterproof failure. In addition, when contacting the external skin, problems such as electric leakage may occur, affecting the user experience. Utility Model Content

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0033] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a heating structure includes an external housing 10 and an internal bracket 20 that are snap-connected to each other. A conductive sheet 40 is provided between the housing 10 and the bracket 20. Both sides of the conductive sheet 40 are closely attached to the housing 10 and the bracket 20 respectively. A conductive coil 30 is provided inside the bracket 20. One side of the conductive coil 30 is closely attached to the inner wall of the bracket 20. The conductive coil 30 is energized to operate, generating a magnetic field, causing the conductive sheet 40 to generate heat under the action of the magnetic field, and transferring the heat to the closely attached housing 10, so that the heated housing 10 can conduct heat or heat treatment on an external object or external skin.

[0034] Specifically, by arranging the bracket 20 between the conductive coil 30 and the conductive sheet 40 for separation, an isolated state is formed between the conductive coil 30 and the conductive sheet 40, with no contact points between them and no need for wires to connect. Thus, its waterproof performance can be maximally enhanced. Moreover, there will be no such situations as electric leakage, which may affect the user experience. The specific working principle is that, through an external power supply or by setting a storage battery inside the beauty device, operating electric energy is provided for the heating structure. Thereby, an alternating current with a certain frequency is passed through the conductive coil 30, causing the conductive coil 30 to start operating and generate an alternating magnetic field with a continuously changing direction. Eddy currents will appear inside the conductive sheet 40 in the alternating magnetic field (the reason can refer to Faraday's law of electromagnetic induction). This is caused by the eddy electric field pushing the carriers in the conductor (i.e., the electrons in the conductive sheet 40) to move; the Joule heat effect of the eddy currents causes the conductive sheet 40 to heat up, thus achieving heating.

[0035] Secondly, as Figure 4 shown, since the middle part of the conductive sheet 40 is provided with an opening, the remaining parts on both sides thereof form a structure connecting the two end parts, enabling the conductive sheet 40 to form a closed current loop. Or through the round holes at both ends of the conductive sheet 40, current loops are respectively formed at both ends. The conductive sheet 40 can be made of various metals with conductive properties, such as iron sheets. Preferably, a conductive copper sheet is adopted to improve its ability to generate eddy currents, thereby enhancing its heating ability. Additionally, the conductive coil 30 is preferably wound with insulated copper wires to enhance its ability to generate an alternating magnetic field. The housing 10 and the bracket 20 are preferably made of plastic materials with insulating properties.

[0036] As Figure 2 and Figure 4 shown, preferably, the bracket 20 is further provided with a circuit board 32, and the circuit board 32 is electrically connected to the conductive coil 30, thereby providing operating electric energy for the conductive coil 30.

[0037] Specifically, the beauty device can be connected to the power supply in the form of directly accessing the AC circuit, or a rechargeable lithium battery can be set to provide electrical energy for the circuit board 32. When accessing the AC circuit, the circuit board 32 can also be provided with a step-down and frequency conversion circuit, so that the alternating current can achieve the effect of driving the conductive coil 30 to form a corresponding high-frequency alternating current, thereby generating a corresponding alternating magnetic field, causing the conductive sheet 40 to generate self-heating under the influence of the alternating magnetic field. Similarly, if the lithium battery is used for power supply, the circuit board 32 can be provided with a corresponding step-up and frequency conversion circuit, so that the low-voltage direct current stored in the lithium battery can be converted into high-voltage alternating current, achieving the effect of driving the conductive coil 30 to form a corresponding high-frequency alternating current, thereby generating a corresponding alternating magnetic field, causing the conductive sheet 40 to generate self-heating under the influence of the alternating magnetic field. Among them, other components for controlling voltage and current in the prior art can also be provided on the circuit board 32, so that the entire heating structure can operate normally.

[0038] As Figure 2 and Figure 4 shown, preferably, a foam column 31 is further provided between the circuit board 32 and the conductive coil 30. One end of the foam column 31 is fixedly connected to the circuit board 32, and the other end abuts against the conductive coil 30 and applies a certain pressure to the conductive coil 30 to make it closely fit the inner wall of the bracket 20.

[0039] Specifically, since the range of the alternating magnetic field generated by the operation of the coil is not very large, in order to make its effect on the conductive sheet 40 the best, it is preferred to keep the coil as close as possible to the inner wall of the bracket 20, that is, to make the coil as close as possible to the conductive sheet 40. Using the foam column 31 to support and abut against the conductive coil 30 can utilize both its insulation performance and its characteristic of having a certain elasticity.

[0040] As Figure 3 and Figure 4 shown, preferably, male snap protrusions 11 are provided on the inner wall of the housing 10, and female snap grooves 21 are provided on the outer wall of the bracket 20. The male snap protrusions 11 and the female snap grooves 21 are arranged in corresponding positions to cooperate with each other to form a snap connection, detachably snap-connecting the housing 10 to the bracket 20. First protrusions 12 and second protrusions 13 are respectively provided on both sides of the long side direction of the housing 10, and first grooves 22 and second grooves 23 are respectively provided on both sides of the long side direction of the bracket 20. The first protrusion 12 and the first groove 22 cooperate with each other to form a snap connection; the second protrusion 13 and the second groove 23 cooperate with each other to form a snap connection.

[0041] Specifically, in order to further enhance the safety of the heating structure and the beauty device and improve the user experience, the housing 10 can also be set to a detachable state. By using the cooperation between the male buckle and the female buckle, a detachable or replaceable snap connection is formed, enabling the housing 10 to be removed. Thus, different users can use different housings 10, or the housing 10 can be replaced for separate disinfection and cleaning, or a disposable housing 10 can be used, further improving the user's safety and comfort during use.

[0042] As Figure 3 shown, preferably, a counterbore 24 is provided at the position of the support 20 corresponding to the female buckle groove 21. A certain gap is formed between the counterbore 24 and the end of the side wall of the housing 10. This gap is used to toggle the end of the side wall of the housing 10, so that the male buckle protrusion 11 disengages from the female buckle groove 21, and then the housing 10 can be detached from the support 20.

[0043] Specifically, in order to make it more convenient to detach the housing 10, a counterbore 24 can also be provided on the outer wall of the support 20. The position where the counterbore 24 is opened will not be completely covered by the end of the side wall of the housing 10, that is, a part of the counterbore 24 can be exposed outside the housing 10, thus forming a gap with the end of the housing 10. When people disassemble the housing 10, they can use the gap to buckle the end of the housing 10, so that the male buckle protrusion 11 disengages from the female buckle groove 21 of the support 20, and then the housing 10 can be detached from the support 20 for replacement or cleaning.

[0044] As Figures 1 to 4 shown, preferably, the support 20 is further provided with a medicine pushing chamber 25. The medicine pushing chamber 25 is formed as a cylindrical shape with openings at both ends. One end is fixedly connected to the support 20, and the other end can extend into the beauty device. The ointment or liquid medicine inside the beauty device can be extruded to the external skin through the openings of the medicine pushing chamber 25.

[0045] Specifically, in order to further enhance the use effect of the beauty device, beauty or cleaning ointment or liquid medicine can also be provided inside the beauty device. In order to enable the liquid medicine to be normally extruded to the external skin, it can be understood that corresponding openings are respectively provided on the support 20, the conductive sheet 40, and the housing 10 at the positions corresponding to the openings of the medicine pushing chamber 25, so that the inner cavity of the medicine pushing chamber 25 can communicate with the outside. The bottle of the liquid medicine or ointment can be placed in the medicine pushing chamber 25 in a replaceable form. After use, it can be pulled out from the medicine pushing chamber 25 for replacement.

[0046] As Figure 3 shown, preferably, the housing 10 is further provided with an annular bend 14. The annular bend 14 is provided at the position of the housing 10 corresponding to the opening of the medicine pushing chamber 25 and bends a certain amplitude into the cavity of the medicine pushing chamber 25, so that the annular bend 14 can block the conductive sheet 40.

[0047] Specifically, in order to further shield or surround the conductive sheet 40, a ring-shaped bend 14 can be provided on the housing 10, which bends a certain amplitude towards the cavity part inside the medicine pushing chamber 25 and extends a certain length so as to be relatively fitted with the inner wall of the medicine pushing chamber 25, thereby shielding the conductive sheet 40. At the same time, the ring-shaped bend 14 can also limit the medicine bottle in the medicine pushing chamber 25 to prevent the medicine bottle from falling out.

[0048] Such as Figure 1 and Figure 4 As shown, preferably, mounting rings 26 are further provided at both ends of the long side direction of the bracket 20, and the mounting rings 26 are used to mount the heating structure on an external beauty instrument. In order to mount the heating structure on the beauty instrument, the mounting rings 26 can also be provided by using the structure protruding outward in the long side direction of the bracket 20. It can be understood that corresponding mating structures are also provided at the positions of the beauty instrument corresponding to the mounting rings 26, so that the heating structure can be correctly mounted on the beauty instrument, enabling the beauty instrument to perform corresponding heating treatment on the user and conduct heat treatment on the external skin to improve the beauty effect.

[0049] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present invention.
