[0039] In addition, if the term "and / or" appears, "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship. If the terms "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0040] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0043] In the related art, beauty devices are mostly of integrated design, so in the event of a malfunction, they often need to be replaced or repaired as a whole, and targeted repairs cannot be performed, resulting in high repair costs and low repair efficiency.

[0044] See also Figure 1 As shown, in order to improve the above problems, the embodiment of the present application provides a body structure, so that each module can be flexibly disassembled and assembled, reducing maintenance costs. It should be noted that the body structure provided by the present application is not limited to the application of beauty instruments, but can also be applied to other small electrical appliances, such as shavers, electric toothbrushes, massagers, etc., which are not specifically limited here. For ease of understanding, in the embodiment of the present application, the body mechanism is illustrated by taking a handheld beauty instrument 100 as an example of the application scenario.

[0045] Continue reading Figure 2 As shown, specifically, the fuselage structure includes at least two connection modules and at least one reinforcement assembly 140. The two adjacent connection modules are detachably matched, and each reinforcement assembly 140 is respectively installed at the connection of the two adjacent connection modules to strengthen the connection strength of the two adjacent connection modules and can separate the two adjacent connection modules under the action of external force.

[0046] In this way, when the fuselage structure is in working condition, based on the connection and cooperation between two adjacent connection modules, the reinforcement component 140 can further strengthen the connection strength between the two to ensure the operational stability of the fuselage structure, thereby facilitating the user's grip.

[0047] Exemplarily, in a specific embodiment, the body structure includes two connection modules, which are the control module 110 and the power supply module 120 of the handheld beauty instrument 100. The control module 110 can control the operating state of the handheld beauty instrument 100, and the power supply module 120 is used to supply power to each electronic component of the handheld beauty instrument 100 to ensure the normal operation of the beauty instrument in the power-on state. The control module 110 and the power supply module 120 are independently arranged, and both have a shell structure to be disassembled and assembled through the shells of the two. Of course, electronic components and wiring are also provided inside the shells of the control module 110 and the power supply module 120 to ensure that the control module 110 and the power supply module 120 maintain circuit connectivity on the basis of structural assembly. Ensure the operation of the beauty instrument. In this way, by setting a reinforcement component 140 at the connection between the control module 110 and the power supply module 120, in the operating state of the beauty instrument, the reinforcement component 140 can strengthen the connection strength of the control module 110 and the power supply module 120 to meet the user's handheld operation. When the beauty instrument stops working, the user can separate the reinforcement component 140 with a little force to separate the control module 110 from the power supply module 120, so as to facilitate subsequent maintenance and replacement, realize targeted maintenance, reduce maintenance costs, and improve maintenance efficiency and convenience.

[0048] In some embodiments, each reinforcement component 140 includes two adsorption members that are arranged opposite to each other, and the two adsorption members are respectively installed on two adjacent connection modules.

[0049] Specifically, the two adsorbents arranged opposite to each other can maintain bonding and are respectively installed in two adjacent connection modules. Taking the control module 110 and the power supply module 120 as an example, a adsorbent is installed at the bottom of the control module 110, and correspondingly, a adsorbent is installed at the top of the power supply module 120, so that after the power supply module 120 and the control module 110 are assembled, the two adsorbents are bonded to each other, thereby improving the connection strength between the power supply module 120 and the control module 110. When disassembling, the user only needs to use force to separate the two adsorbents, and then separate the power supply module 120 from the control module 110.

[0050] Continue reading Figure 3 As shown, in some embodiments, each adsorption member includes a magnetic core 141 and an electromagnetic coil 142, and the magnetic core 141 and the electromagnetic coil 142 are stacked.

[0051] Specifically, the magnetic core 141 is a magnet, and the electromagnetic coil 142 can generate a magnetic field when powered on. In this way, during the operation of the beauty instrument, the electromagnetic coil 142 is powered on, which strengthens the magnetism of the two connection modules and increases the adsorption strength of the two, thereby ensuring the user's holding operation needs. During the power-off process, the magnetism of the electromagnetic coil 142 disappears, and the two magnetic cores 141 can maintain a stable fit under the action of their own magnetic force, ensuring daily storage needs. The user only needs to use a little force to separate the two magnetic cores 141 and realize the disassembly of the two connection modules, thereby improving maintenance efficiency and portability.

[0052] Exemplarily, a magnetic core 141 and an electromagnetic coil 142 are installed at the bottom of the control module 110, and correspondingly, a magnetic core 141 and an electromagnetic coil 142 are also installed at the top of the power supply module 120. The magnetic cores 141 of the control module 110 and the power supply module 120 maintain opposite magnetic poles, and the electromagnetic coils 142 of the control module 110 and the power supply module 120 maintain opposite magnetic poles in the power-on state, so that the two adsorbents installed on the control module 110 and the power supply module 120 maintain opposite magnetic poles, and maintain enhanced connection strength after the control module 110 and the power supply module 120 are assembled. In the power-off state, the magnetic cores 141 of the control module 110 and the power supply module 120 can still maintain a certain adsorption strength, ensuring the daily assembly of the control module 110 and the power supply module 120. It is only necessary to separate the two by force during maintenance, which is convenient for repairing a part of the beauty instrument, troubleshooting the faulty part, replacing a module, or carrying the beauty instrument out, thereby improving the repair efficiency and portability of the beauty instrument. The structural design of the magnetic core 141 and the electromagnetic coil 142 ensures the stability of the body structure and the easy disassembly of each connecting module, further improving the practicality of the product and user satisfaction.

[0053] Continue reading Figure 4 and Figure 6 As shown, in some embodiments, among two adjacent connection modules, one end of one connection module is provided with a connection sleeve 114, and the other connection module is provided with a plug-in column 124, the plug-in column 124 is plugged into and matched with the connection sleeve 114 to define a accommodating cavity 115, and the magnetic core 141 and the electromagnetic coil 142 are sleeved on the outside of the plug-in column 124 and located in the accommodating cavity 115.

[0054] Specifically, the connection sleeve 114 and the plug-in column 124 can be plugged together to maintain a certain connection strength. The magnetic core 141 and the electromagnetic coil 142 are both annular structures, and the inner diameter is greater than or equal to the outer diameter of the plug-in column 124, and the outer diameter is smaller than the inner diameter of the connection sleeve 114, so that the magnetic core 141 and the electromagnetic coil 142 can be sleeved on the outside of the connection column and confined in the connection sleeve 114, ensuring the stable installation of the magnetic core 141 and the electromagnetic coil 142.

[0055] The embodiment of the present application further provides a handheld beauty instrument 100, comprising a body structure and a massage head 150 in any of the above embodiments, wherein the massage head 150 is detachably mounted on one end of the body structure.

[0056] Specifically, the massage head 150 can be installed on the end of the body structure by screws, and the circuit is kept connected, so that the user can hold the body structure to control the operating position of the massage head 150.

[0057] This embodiment has the fuselage structure of any of the above embodiments, and therefore has all the beneficial effects of the fuselage structure of any of the above embodiments, which will not be described in detail here.

[0058] Continue reading Figure 5 As shown, in some embodiments, the body structure includes three connection modules and two reinforcement components 140, and the three connection modules are respectively a control module 110, a power supply module 120 and a charging module 130. One end of the control module 110 is connected to the massage head 150, the power supply module 120 is installed at the end of the control module 110 away from the massage head 150, and the charging module 130 is installed at the end of the power supply module 120 away from the control module 110. A reinforcement component 140 is provided between the control module 110 and the power supply module 120, and between the power supply module 120 and the charging module 130.

[0059] Exemplarily, the massage head 150, the control module 110, the power supply module 120 and the charging module 130 are sequentially spliced ​​from top to bottom, the massage head 150 is assembled to the top of the control module 110 by screws, the power supply module 120 is assembled to the bottom of the control module 110, and a reinforcement component 140 is provided at the connection between the two. The charging module 130 is assembled to the bottom of the power supply module 120, and a reinforcement component 140 is also provided at the connection between the two. The connection structure between the charging module 130 and the power supply module 120 is the same as the connection structure between the control module 110 and the power supply module 120. The specific principle can refer to the connection method between the control module 110 and the power supply module 120 in the above embodiment, and no further details are given here.

[0060] The control module 110, the power supply module 120 and the charging module 130 are all provided with an inner and outer shell structure, the outer shell is made of a lightweight material, and the inner shell is hard plastic, so as to protect the surface of the body structure and the internal electronic components.

[0061] It is understandable that the handheld beauty instrument 100 may also include a charging stand. When power replenishment is needed, the charging module 130 only needs to be placed on the charging stand and connected to an external power source for charging. Of course, the charging method of the charging module 130 is not limited to wireless or wired, and can be selected according to actual needs.

[0062] In other embodiments, the power supply module 120 and the charging module 130 can also be integrated into one module, which can also meet the power supply and charging requirements, ensure user needs, and thus simplify the overall structure. Its operating principle is the same as the above embodiment, and will not be repeated here.

[0064] Specifically, the first housing 111 may include the inner and outer shell structures in the above-mentioned embodiments, and the touch screen 112 is installed on the outer side of the first housing 111 and has a variety of control buttons. A microprocessor and other necessary electronic components are installed on the first circuit board 113 to receive and process user operation instructions. In this way, when the touch screen 112 is connected to the first circuit board 113, the user can select different beauty modes and functions through touch operation, and the touch screen 112 sends corresponding control instructions to the massage head 150 through the first circuit board 113 to adjust the operation mode of the beauty instrument.

[0065] Furthermore, the touch screen 112 is in a curved structure and is embedded in the first housing 111. The curved surface of the touch screen 112 allows the touch screen 112 to be integrated with the outer surface of the first housing 111, maintaining the overall aesthetics. Moreover, the user can intuitively control various functions of the beauty instrument through the touch screen 112, thereby improving the user experience.

[0066] In some embodiments, the power supply module 120 includes a second shell 121 , a battery 122 , and a second circuit board 123 . The battery 122 and the second circuit board 123 are both installed in the second shell 121 , and the battery 122 is electrically connected to the second circuit board 123 .

[0068] In some embodiments, the charging module 130 includes a third shell 131 , a charging coil 132 and a third circuit board 133 . The charging coil 132 and the third circuit board 133 are both installed in the third shell 131 , and the charging coil 132 is electrically connected to the third circuit board 133 .

[0069] Specifically, the third housing 131 also includes the inner and outer shell structures in the above embodiment, and the charging coil 132 supports wireless charging to store energy for the battery 122. The third circuit board 133 can control the charging of the charging coil 132, thereby improving the convenience of using the beauty instrument.

[0070] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
