Description

Technical Field

[0001] The utility model specifically relates to a mounting structure of a multifunctional toothbrush. Background Art

[0002] In addition to the function of brushing teeth, electric toothbrushes in the prior art can also be installed with caries detection heads for caries detection. However, the replacement operation of the dual-purpose brush heads of current electric toothbrushes is relatively simple. The structure of direct extraction and insertion can easily lead to instability of the electrical connection structure of the caries detection head. In other words, the electrical connection structure of the caries detection head is only contacted by pins, and there is no position limiting structure to fix the installation position of the caries detection head. Redundant telecommunication signal transmission is unstable, affecting the effectiveness of detection.

DETAILED DESCRIPTION

[0024] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0025] like Figures 1 to 7 The figure shows a mounting structure 10 of a multifunctional toothbrush of the present application, comprising: a handle housing 11, a first brush head assembly 14 and a second brush head assembly 15. The first brush head assembly 14 can be detachably mounted on the upper end of the handle housing 11 for teeth cleaning, and the second brush head assembly 15 can be detachably mounted on the upper end of the handle housing 11 for caries detection. The handle housing 11 is equipped with: a battery 16, a control board 17, a reciprocating motor and a vibration iron core 18. The battery 16 is used to provide power, the control board 17 is used to analyze the detection information of the second brush head assembly 15, so that the electric toothbrush has independent data processing capabilities, and the reciprocating motor is used to drive the first brush head assembly 14. The vibration iron core 18 is horizontally slidably connected to the handle housing 11 through a sliding guide plate 19, the output end of the reciprocating motor is connected to the vibration iron core 18 to drive the vibration iron core 18 to reciprocate in the horizontal direction, and the control board 17 and the reciprocating motor are both electrically connected to the battery 16. The upper end surface of the handle housing 11 is provided with a data interface 12 for receiving detection information of the second brush head assembly 15, and the data interface 12 is electrically connected to the control board 17. The upper end of the handle housing 11 is fixed with a magnetic mounting table 13 for detachably mounting the first brush head assembly 14 and the second brush head assembly 15. Specifically:

[0026] The first brush head assembly 14 includes: a first mounting shell 141 and a cleaning brush head 145, through which the teeth can be cleaned. The first mounting shell 141 is formed with a horizontal guide groove 142, and the cleaning brush head 145 cooperates with the horizontal guide groove 142 through its own guide flange, so that it can be slidably installed on the upper end of the first mounting shell 141 in the horizontal direction. The first mounting shell 141 is fixed with a first magnetic mounting sleeve 143, and the first mounting shell 141 body is detachably installed on the top of the handle shell 11 through the first magnetic mounting sleeve 143 being sleeved on the outer periphery of the magnetic mounting platform 13, and the vibration iron core 18 passes through the magnetic mounting platform 13 and is inserted into the socket 146 formed at the lower end of the cleaning brush head 145. That is to say, when the cleaning brush head 145 is needed, the first mounting shell 141 can be directly mounted on the outer periphery of the magnetic mounting platform 13 through the first magnetic mounting sleeve 143 to mount the cleaning brush head 145 on the upper end of the handle housing 11. At this time, the vibration iron core 18 passes through the magnetic mounting platform 13 and is inserted into the cleaning brush head 145. When the reciprocating motor is started, the reciprocating motor will drive the vibration iron core 18 to reciprocate along the horizontal guide groove 142, thereby driving the cleaning brush head 145 to vibrate to clean the teeth in the oral cavity. Such a mounting structure is simple and it is easy to replace the brush head.

[0027] The second brush head assembly 15 includes: a second mounting shell 151 and an image collector 156, through which the image collector 156 can be used to collect images of teeth. The image collector 156 is fixed to the upper end of the second mounting shell 151, and the second mounting shell 151 is equipped with a data transmission plug 157 for inserting into the data interface 12 to transmit the collected information of the image collector 156, and the data transmission plug 157 is electrically connected to the image collector 156.

That is to say, when the second brush head assembly 15 is needed, unplug the first brush head assembly 14, and then the second mounting shell 151 is mounted on the outer periphery of the magnetic mounting platform 13 through the second magnetic mounting sleeve 158 to install the second brush head assembly 15. At this time, the data transmission plug 157 is plugged into the data interface 12. When the image acquisition device 156 acquires relevant information of the teeth in the oral cavity, the acquired information will be sent to the control board 17 through the data transmission plug 157 and the data interface 12 for data analysis. It is easy to use and the brush head can be replaced quickly.

[0028] Furthermore, shaft holes 131 are formed on both sides of the magnetic mounting platform 13, and fixing holes are formed on the inner wall of the handle shell 11. The magnetic mounting platform 13 is fixed to the handle shell 11 by the mounting shaft 132 passing through the two shaft holes 131 in sequence and inserted into the fixing hole on the inner wall of the handle shell 11. The first magnetic mounting sleeve 143 and the second magnetic mounting sleeve 158 are respectively formed with a first limiting recess 144 and a second limiting recess 159, and the first limiting recess 144 and the second limiting recess 159 are respectively used to clamp into the mounting shaft 132 when the first magnetic mounting sleeve 143 and the second magnetic mounting sleeve 158 are sleeved on the outer periphery of the magnetic mounting platform 13, thereby limiting the mounting position 203 of the first magnetic mounting sleeve 143 and the second magnetic mounting sleeve 158 relative to the handle shell 11, so as to effectively prevent the first mounting shell 141 and the second mounting shell 151 from rotating, thereby ensuring the smoothness of the reciprocating motion of the cleaning brush head 145 and the stability of the electrical connection between the data transmission plug 157 and the data interface 12.

[0029] The multifunctional toothbrush installation structure 10 can realize the rapid replacement of the first brush head assembly 14 and the second brush head assembly 15 by designing the structure of the first brush head assembly 14 and the second brush head assembly 15, and can also ensure the stability of the electrical connection structure of the first brush head assembly 14 and the second brush head assembly 15, thereby ensuring the effectiveness of the first brush head assembly 14 in cleaning teeth and the second brush head assembly 15 in detecting teeth. At the same time, the control panel 17 is integrated and installed in the handle housing 11, which can make the second brush head assembly 15 more comprehensive and independent in detecting teeth, and provide a better user experience.

The electrical terminal of the threaded interface 155 is formed with a threaded hole, and the data transmission plug 157 is detachably installed at the lower end of the second installation housing 151 by screwing into the threaded hole. In this design, when the second brush head assembly 15 is not in use, the data transmission plug 157 can be disassembled and stored, thereby preventing it from being damaged by external forces.

[0031] As a specific embodiment, a mounting hole 152 is formed at the upper end of the second mounting shell 151 for mounting the image collector 156. A plurality of silicone brushes 154 are provided on the periphery of the mounting hole 152 for removing the covering on the teeth when the image collector 156 is performing image acquisition, thereby improving the convenience of the image collector 156 in acquiring tooth images. A through hole 153 is formed at the bottom of the mounting hole 152, through which the electrical connection line between the image collector 156 and the data transmission plug 157 can pass.

[0032] As a specific implementation, the data transmission interface adopts a concentric cylindrical data interface 12, which ensures excellent waterproof performance and is not easy to be damaged.

In addition, the flange is formed with a plurality of clamping grooves, and the plurality of clamping grooves are respectively used for corresponding clamping protrusions 202 to be clamped, so that the circumferential rotation of the mounting frame 20 can be limited. The lower end of the handle housing 11 is threadedly installed with a rubber base 21 for sealing the mounting cavity and pressing the mounting frame 20. In this way, the mounting frame 20 can be stably installed in the handle housing 11, and it is easy to disassemble.
