[0035] The utility model provides a body structure of an oral cleaning device.

[0036] In the embodiment of the present utility model, please refer to Figures 1 to 5 The body structure 100 of the oral cleaning device includes a metal shell 110, a bottom cover 120, a core bracket 130, a power supply unit 140, a main control board 150 and an insulating layer 160; the lower end of the metal shell 110 has an opening 111; the bottom cover 120 is installed at the lower end of the metal shell 110 and blocks the opening 111; the core bracket 130 is fixed in the metal shell 110; the power supply unit 140 is installed at one end of the core bracket 130 adjacent to the bottom cover 120; the main control board 150 is provided with a plurality of holes 111; the bottom cover 12 ... The board 150 is electrically connected to the power supply unit 140. The main control board 150 is connected to the outer peripheral side of the movement bracket 130. The main control board 150 includes a lower area 151 corresponding to the power supply unit 140 and an extended area 152 connected to the bottom end of the lower area 151, and the extended area 152 extends into the bottom cover 120; the insulating layer 160 is arranged between the metal shell 110 and the main control board 150, and the insulating layer 160 covers the extended area 152 and at least part of the lower area 151 from bottom to top.

[0037] In this embodiment, the body structure 100 of the oral cleaning appliance uses a metal shell 110, which has high structural strength and is not easy to be damaged, and can improve the texture and feel of the oral cleaning appliance, thereby improving the product quality. At the same time, the oral cleaning appliance uses a metal shell 110, which is easier to clean than a plastic shell, and is not prone to yellowing, dirt, etc. The metal shell 110 can specifically be made of lightweight metal materials with good elasticity such as stainless steel, zinc alloy, copper alloy, and titanium alloy. The bottom cover 120 can be made of metal material, plastic material, or a double-layer shell material with an inner layer of plastic and an outer layer of metal. It can be selected and designed according to actual needs, and is not specifically limited here. The bottom cover 120 can be connected to the metal shell 110, or it can be connected to other structures in the metal shell 110, for example, the bottom cover 120 can be connected to the insulating inner shell 190. The bottom cover 120 is used to block the lower end opening 111 of the metal shell 110, and a plug-in structure can be set on the bottom cover 120 to realize the charging of the oral cleaning appliance.

[0038] The movement bracket 130 is used to provide support and installation for internal structures such as the motor, power supply unit 140, and main control board 150. The structure of the movement bracket 130 can be many, which is not specifically limited here. The movement bracket 130 can be connected to the metal shell 110, or it can be connected to other structures in the metal shell 110, for example, the movement bracket 130 is fixedly connected to the insulating inner shell 190. The power supply unit 140 can specifically be a battery, which is used to provide power for the entire oral cleaning device. By providing an insulating layer 160 between the metal shell 110 and the main control board 150, compared with hollowing out the part of the metal shell 110 corresponding to the main control board 150, the method of embedding an insulating plate in the hollow area of ​​the metal shell 110 can ensure the integrity and consistency of the metal shell 110 and reduce the processing cost. The main control board 150 can be fixedly connected to the movement bracket 130 by buckles, screws, etc. The main control board 150 has an extension area 152 extending into the bottom cover 120, and the extension area 152 can be used as a Bluetooth receiving area. Since the Bluetooth module is usually arranged at the bottom cover 120, the extension area 152 extending into the bottom cover 120 is closer to the Bluetooth module, which can shorten the wiring distance.

[0039] The body structure 100 of the oral cleaning device of the utility model is such that the main control board 150 includes a lower area 151 corresponding to the power supply area and an extended area 152 extending into the bottom cover 120, and the extended area 152 can be used as a Bluetooth receiving area. The insulating layer 160 covers the extended area 152 and at least part of the lower area 151 of the main control board 150 from bottom to top, and can simultaneously insulate the extended area 152 of the main control board 150 and the metal shell 110, and the lower area 151 of the main control board 150 corresponding to the power supply unit 140 and the bottom cover 120. When the bottom cover 120 is also made of metal material, the body structure 100 can be fully insulated to improve the insulation effect of the whole device.

[0040] In one embodiment, if Figures 3 to 5 As shown, the lateral width of the extension area 152 is smaller than the lateral width of the lower area 151 ; the insulating layer 160 includes an outer shell insulating portion 161 and a bottom cover 120 insulating portion, the outer shell insulating portion 161 is adapted to cover the lower area 151 , and the bottom cover 120 insulating portion is adapted to cover the extension area 152 .

[0041] In this embodiment, since the extension area 152 extending into the bottom cover 120 has fewer functions, the lateral width of the extension area 152 is smaller than the lateral width of the lower area 151, thereby reducing the space occupied by the main control board 150 in the bottom cover 120 while meeting the functional requirements. The insulating layer 160 is divided into a shell insulating portion 161 and a bottom cover 120 insulating portion, the shell insulating portion 161 is adapted to cover the lower area 151, and the bottom cover 120 insulating portion is adapted to cover the extension area 152, thereby minimizing the insulating layer 160 while ensuring the insulation effect, and effectively reducing the cost.

[0042] In one embodiment, please refer to Figures 3 to 6 , a socket 153 is provided in the lower area 151 of the main control board 150, and the insulating layer 160 extends from bottom to top to cover the socket 153. Usually, an inductor is also provided in the lower area 151 of the main control board 150. The inductor, the socket 153, etc. provided in the lower area 151 are prone to leakage from the metal housing 110 during operation. By extending the insulating layer 160 from bottom to top to cover the socket 153, the area on the main control board 150 where the socket 153, the inductor and other electronic components are provided can be effectively insulated to ensure the overall insulation effect.

[0043] In one embodiment, if Figures 2 to 6As shown, the power supply unit 140 extends in the up-down direction, and the extension length of the insulating layer 160 in the up-down direction is less than the extension length of the power supply unit 140 in the up-down direction. It can be understood that the electronic components such as the inductor and the socket 153 are mainly concentrated in the lower area 151 of the main control board 150, and the upper area of ​​the main control board 150 is not prone to leakage. By making the extension length of the insulating layer 160 less than the extension length of the power supply unit 140, the length of the insulating layer 160 can be further shortened while ensuring insulation between the main control board 150 and the metal housing 110, thereby reducing costs.

[0044] In one embodiment, please refer again to Figures 2 to 6 The body structure 100 of the oral cleaning device also includes a shading foam 170 fixed to the lower area 151, and at least two light-transmitting holes 171 are opened on the shading foam 170. A display element 180 is provided corresponding to the light-transmitting holes 171 on the lower area 151; the upper end of the insulating layer 160 is fixedly connected to the shading foam 170, and the lower end is fixedly connected to the main control board 150.

[0045] In this embodiment, the display element 180 can specifically be a power indicator light and a flight mode indicator light, and the metal shell 110 is provided with a light-transmitting area corresponding to the display element 180. The light-shielding foam 170 can be fixed to the lower area 151 of the main control board 150 by bonding or the like. The light-shielding foam 170 can prevent the light from being transmitted from multiple display elements 180, so that the light transmitted from the display element 180 by the metal shell 110 is more concentrated. It can be understood that the light-shielding foam 170 can also play an insulating role, so that the upper end of the insulating layer 160 is fixedly connected to the light-shielding foam 170, which makes the fixed connection of the insulating layer 160 more convenient and stable on the one hand, and the insulating layer 160 can be connected with the foam to reliably insulate the main control board 150 on the other hand. The lower end of the insulating layer 160 can be fixedly connected to the main control board 150 by bonding or the like.

[0046] In one embodiment, if Figures 4 to 6 As shown, the light shielding foam 170 is arranged at the middle of the length direction of the power supply unit 140, and the insulating layer 160 extends from the lower end of the light shielding foam 170 to cover the extended area 152. After many experiments, the insulating layer 160 only covers the area of ​​the main control board 150 below the light shielding foam 170 to ensure reliable insulation of the whole machine. In this way, the length of the insulating layer 160 can be minimized, saving materials and further reducing costs.

[0047] In one embodiment, the insulating layer 160 is made of a flexible material, and the insulating layer 160 is bonded and fixed to the light-shielding foam 170 and the main control board 150. The insulating layer 160 can be made of a flexible insulating material such as acetate cloth. By making the insulating layer 160 a flexible material, it can be flexibly bent, which makes it easier for the insulating layer 160 to cover and insulate the electronic components on the main control board 150. The method of bonding and fixing the insulating layer 160 to the light-shielding foam 170 and the main control board 150 is simple and reliable to operate.

[0048] In one embodiment, the thickness of the insulating layer 160 is greater than or equal to 0.1 mm, and less than or equal to 0.5 mm. Specifically, the thickness of the insulating layer 160 can be 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.5 mm, etc. If the thickness of the insulating layer 160 is less than 0.1 mm, the thickness of the insulating layer 160 is too thin, and the insulation effect is not good. If the thickness of the insulating layer 160 is greater than 0.5 mm, the thickness of the insulating layer 160 is too thick, and the space occupied is large, which is not conducive to the miniaturization of the whole machine. By making the thickness of the insulating layer 160 greater than or equal to 0.1 mm, and less than or equal to 0.5 mm, the space occupied by the insulating layer 160 is reduced while ensuring a better insulation effect, so that the radial size of the fuselage structure 100 can be designed to be smaller, which is conducive to the miniaturization of the whole machine.

[0049] In one embodiment, please refer to Figures 2 to 6 The body structure 100 of the oral cleaning device also includes an insulating inner shell 190, a metal outer shell 110 is sleeved outside the insulating inner shell 190, a movement bracket 130 is arranged in the insulating inner shell 190, and the insulating inner shell 190 is provided with a revealing window 191 corresponding to the main control board 150; the insulating layer 160 is arranged corresponding to the revealing window 191.

[0050] In this embodiment, the movement bracket 130 can be fixedly connected to the insulating inner shell 190 by means of clamping, screw connection, etc. By setting the insulating inner shell 190, the electrical structure set in the insulating inner shell 190 can be insulated to a large extent. The insulating inner shell 190 is provided with a revealing window 191 corresponding to the main control board 150 to facilitate the connection of components such as buttons of the main control board 150 with the metal shell. The insulating layer 160 is arranged at the revealing window 191 to effectively insulate the main control board 150 and the metal shell and the bottom cover 120, which can ensure the insulation effect of the whole machine and prevent the metal shell 110 from leaking electricity.

[0051] The utility model also proposes an electric toothbrush, which includes a brush head assembly and a body structure 100 of an oral cleaning appliance. The specific structure of the body structure 100 of the oral cleaning appliance refers to the above embodiment, and the brush head assembly is connected to the body structure 100 of the oral cleaning appliance; since the electric toothbrush adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
