Description

Technical Field

[0001] The present application belongs to the technical field of oral cleaning appliances, and relates to a fixing structure of a function indicator light, which is used on oral cleaning appliances such as electric toothbrushes. Background Art

[0002] Electric toothbrushes mainly use the rapid rotation or vibration of the electric motor to make the toothbrush head vibrate at high frequencies, instantly breaking down the toothpaste into fine foam and deeply cleaning the gaps between teeth. Electric toothbrushes usually have various function indicators on the operation panel to indicate the working status of the electric toothbrush. One way is to set a transparent area on the shell and illuminate the transparent area with light from the inside of the shell to achieve the indication function. However, this method has a high production cost because the shell separates the light transmission and the indication brightness is insufficient. Exposing the function indicator directly on the outside of the shell can increase the indication brightness, but it is necessary to solve the problem of fixing and waterproofing the function indicator. Utility Model Content

[0003] The purpose of the present application is to provide a fixing structure for a function indicator light, which is used on an electric toothbrush and does not require gluing to fix it, thereby avoiding the influence of glue on light transmittance and has good waterproof and sealing performance.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in some embodiments of the present application to clearly and completely describe the technical solutions in some embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown in the figure, this embodiment is an electric toothbrush, which includes a brush head and a handle. The brush head is not shown. The handle includes a housing 12 and a core assembly and a control circuit board 11 installed inside the housing 12. The brush head is connected to the driving shaft of the core assembly. The control circuit board 11 is provided with a button 111, which is a power switch or a function selection button. Since the internal structure and working principle of the electric toothbrush of this embodiment belong to the prior art in this field, the detailed internal structure thereof will not be described in detail.

[0026] In this embodiment, the fixing structure for the function indicator light of the electric toothbrush includes a housing 12, a panel cover 14, a seal 13 and an indicator light group 15. The housing 12 is provided with a through hole 121. The housing 12 is provided with a first concave platform 122 for defining the seal 13 and a second concave platform 123 for defining the panel cover 14 around the through hole 121. The seal 13 seals and covers the through hole 121.

[0027] A first cavity 131131 is formed on the outer surface of the sealing member 13 . The indicator light group 15 is disposed in the first cavity 131131 and clamped between the panel cover 14 and the sealing member 13 . A lamp hole 141 for exposing the indicator light group 15 is provided on the panel cover 14 .

[0028] The fixing structure of the functional indicator light of the present technical solution utilizes the panel cover 14 and the seal 13 to clamp and fix the indicator light group 15, and there is no need to glue the indicator light group 15, so as to achieve a better light transmission effect of the indicator light while having good waterproof and sealing performance.

[0029] It should be noted that the side of the seal 13 abuts against the edge of the first recess 122 to limit the position of the seal 13 on the outer shell 12. Similarly, the side of the panel cover 14 abuts against the edge of the second recess 123 to limit the position of the panel cover 14 on the outer shell 12.

[0030] In this embodiment, a plurality of slots 124 are provided on the surface of the first concave platform 122, and the plurality of slots 124 are evenly arranged around the through hole 121. For example, the slots 124 are slots 124 with a circular cross section that penetrates the housing 12. A plurality of clamping posts 134 are provided on the inner surface of the sealing member 13, and the clamping posts 134 are adapted to the shape of the slots 124, and the clamping posts 134 are interference-fitted in the slots 124, so that the sealing member 13 is connected to the housing 12.

[0031] In this embodiment, the panel cover 14 is attached to the second recess 123 of the outer shell 12 by ultrasonic welding or gluing, so that the outer surface of the panel cover 14 is flush with the outer surface of the outer shell 12, and the inner surface of the panel cover 14 is in contact with the seal 13 to press the seal 13 onto the first recess 122 of the outer shell 12.

[0032] In this embodiment, the indicator light group 15 includes a plurality of lamp beads 151. When the indicator light group 15 is installed in the first concave cavity 131131, each lamp bead 151 is correspondingly arranged in a lamp hole 141. The light generated by the lamp bead 151 can pass through the lamp hole 141 and can be seen by the user. The shape of the lamp hole 141 is adapted to the lamp bead 151, so that the end of the lamp bead 151 is flush with the outer surface of the shell 12, thereby increasing the aesthetics and hand feel.

[0033] In this embodiment, a second cavity 132 is further formed on the outer surface of the seal 13, and a keycap 16 is arranged in the second cavity 132. The keycap 16 is clamped between the panel cover 14 and the seal 13, and a key hole 142 for exposing the keycap 16 is provided on the panel cover 14. A protrusion 135 is provided on the inner surface of the seal corresponding to the second cavity 132, and the protrusion 135 conflicts with the key 111 on the control circuit board 11. The number of second cavities 132 and keycaps 16 corresponds to the key 111 of the control circuit board 11, and can be multiple.

[0034] In this embodiment, the inner surface of the seal 13 is further formed with a boss 133, which matches the through hole 121. In this way, the seal 13 fills the inside of the through hole 121, increasing the limitation of the seal 13 and also enhancing the sealing performance. The seal 13 is made of silicone material or rubber material.

[0035] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
