[0033] The core of the utility model is to provide a toothbrush handle and a children's toothbrush to solve the problem that water easily enters the toothbrush handle and causes failure of the electric control component.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1-Figure 7 As shown, the utility model specifically provides a toothbrush handle 1. Those skilled in the art should be able to understand that the toothbrush handle 1 is an important part of a toothbrush. In addition to the toothbrush handle 1, the toothbrush generally also has a brush head 2, on which a brush is arranged. The brush head 2 can be an integrated structure with the toothbrush handle 1, or a structure in a split connection. In actual application, the configuration can be selected according to actual needs. The toothbrush handle 1 specifically includes a main body 11, a cover plate 12, an electric control component 13 and a waterproof coating layer 14.

[0036] Among them, the main body 11 has an installation opening 110, and the installation opening 110 mainly provides an installation entrance for installing related devices in the toothbrush handle 1; the cover plate 12 is sealed and connected to the installation opening 11, and is enclosed with the main body 11 to form an installation cavity 16. The sealing connection method between the cover body 12 and the installation opening 11 can be but is not limited to ultrasonic welding. For example, a snap-on connection with a sealing ring or a sealant structure can be used. In actual application, the configuration can be selected according to actual needs.

[0037] In addition, the electronic control component 13 is installed in the installation cavity 16, wherein the electronic control component 13 is mainly used for adding electronic control functions to the toothbrush handle 1, such as the electronic control light effect function mentioned below. The electronic control component 13 can be fixed to the installation cavity 16 by fasteners 17, or it can be installed in the installation cavity 16 by snap-fitting. In actual application, the arrangement can be selected according to actual needs.

[0038] In addition, the waterproof coating layer 14 is coated on the outside of the main body 11 and the cover plate 12, and wraps the main body 11 and the cover plate 12 as a whole. Its function includes secondary coating of at least the position where the main body 11 and the cover plate 12 are sealed and connected to form an integral structure, so as to achieve the purpose of secondary waterproofing.

[0039] In actual application, the toothbrush handle 1 forms a first waterproof structure through the sealed connection between the cover plate 12 and the installation opening 110, and wraps the main body 11 and the cover plate 12 into a whole and forms a second waterproof structure through the waterproof coating layer 14 coated on the outside of the main body 11 and the cover plate 12, so that the toothbrush handle 1 has two waterproof structures, which greatly improves the waterproof effect of the toothbrush handle 1 and effectively avoids the occurrence of water ingress into the toothbrush handle 1 causing failure of the electronic control component.

[0040] It should be noted that the main body 11 and the cover 12 are preferably sealed and connected by ultrasonic welding, because the first waterproof sealing effect between the main body 11 and the cover 12 is better through ultrasonic welding. Of course, it is understandable that other sealing connection methods such as hot melting, or detachable sealing connection methods can also be used, such as the main body 11 and the cover 12 are connected by a snap connection or fastener, and then a sealing structure such as a sealing ring or a sealant is used to achieve it. In actual application, the configuration can be selected according to actual needs, and no more specific restrictions are made here.

[0041] In some specific embodiments, reference Figure 1 Combination Figure 6 As shown, the waterproof coating layer 14 can be specifically designed as a hard coating structure or a soft coating structure, wherein the soft coating structure can improve the feel of the toothbrush handle 1, and the soft coating structure is more suitable for children. In actual application, the waterproof coating layer 14 can be designed into a corresponding structure according to different feel requirements. It should be noted that in order to make it easier to process the waterproof coating layer 14 coated on the outside of the main body 11 and the cover plate 12, the waterproof coating layer 14 can specifically adopt a glue layer structure, such as a hard glue layer or a soft glue layer can be formed by injection molding on the overall outer side formed by the sealed connection between the main body 11 and the cover plate 12.

[0042] In some specific embodiments, reference Figure 1 and Figure 2 , combined with Figure 5As shown, the above-mentioned electric control component 13 may specifically include a light effect electric control component, which may specifically include a circuit board 131, a light emitter 132 disposed on the circuit board 131, and a capacitive sensing switch 133. Among them, the circuit board 131 has a control circuit to realize the corresponding light effect function, the light emitter 132 may specifically be a semiconductor light-emitting device, such as an LED lamp, etc., and the capacitive sensing switch 133 mainly realizes the switch control of the circuit through touch sensing. Of course, in addition to this, the light effect electric control component should generally also include a battery 134 to provide power for the light effect electric control component. By designing the electric control component 13 into the structural form of the above-mentioned light effect electric control component, the toothbrush handle 1 can obtain certain light effect functions by touching the capacitive sensing switch 133, such as flashing, alternating light colors, or other light effects, etc., which are not further specifically limited here. It should be noted that the above-mentioned light effect electric control component is only an example of the electric control component 13 of the utility model. In actual application, other types of electric control components 13 may also be included, such as electric control components of audio or video such as electric music boxes.

[0043] In addition, by using a capacitive sensing switch 133 to control the corresponding control circuit on the circuit board 131, compared with the traditional push-type switch, there is no need to consider the design of the pressing stroke of the switch. For example, there is no need to design the wall thickness of the cover 12 to be very thin in order to consider the pressing of the switch, or to set a soft rubber structure on the cover 12, which is more conducive to ensuring the overall waterproof sealing of the toothbrush handle 1.

[0044] In a further embodiment, referring to Figure 1 Combination Figure 7 As shown, in order to facilitate more accurate touching of the position of the capacitive sensing switch 133, a mark 141 corresponding to the position of the capacitive sensing switch 133 is provided on the outer side of the waterproof coating layer 14. The mark can be an icon formed on the outer side of the waterproof coating layer 14, or a local protrusion, depression, ring or other structural form formed on the outer surface of the waterproof coating layer 14. In actual application, the corresponding structural form can be selected according to actual needs, and no further specific limitation is made here.

[0045] In some specific implementations, the inner side of the main body 11 may be generally provided with reinforcing ribs 111. The structural strength of the main body 11 can be improved by designing the reinforcing ribs 111. The reinforcing ribs 111 may be formed by, but not limited to, integral injection molding with the main body 11.

[0046] In a further embodiment, referring to Figure 1 and Figure 2 , combined with Figure 5As shown, the reinforcing rib 111 may specifically include a first positioning rib 111a and a second positioning rib 111b, wherein the first positioning rib 111a is mainly used to position the circuit board 131, and its structural form may be, but not limited to, a fixed column structure designed in the main body 11, and a threaded hole may be designed on the fixed column structure, so that the circuit board 131 can be fixed on the first positioning rib 111a by fasteners, etc. Of course, at this time, the circuit board 131 should also be provided with a corresponding fixing hole; the second positioning rib 111b is mainly used to position the illuminant 132, and its specific structural form may be, but not limited to, a rib plate structure designed in the main body 111, and a positioning structure adapted to the illuminant 132 is provided on the rib plate structure. By designing the reinforcing rib 111 into the above structural form, not only the structural strength of the main body 11 is strengthened, but also the installation and positioning of the circuit board 131 and the illuminant 132 are made more convenient.

[0047] It should be noted that the number of the above-mentioned light-emitting bodies 132 can be one, or it can be designed to be multiple (that is, two or more). When the number of light-emitting bodies 132 is multiple, they can be selected to light up at the same time, or they can be designed to flash alternately, and the control logic of the light effect can be selected and designed according to the needs; in addition, the light effects emitted by different light-emitting bodies 132 can be the same or different. In the actual application process, they can be configured according to actual needs, and no more specific restrictions are made here. In addition, a light-transmitting area 112 corresponding to the installation position of the light-emitting body 132 will be provided on the main body 11, wherein the reinforcing rib 111 is arranged on the main body 11 in an area outside the corresponding light-transmitting area 112. By designing the aforementioned reinforcing rib 111 on the main body in an area outside the corresponding light-transmitting area 112, the brightness of the light emitted by the light-emitting body 132 through the light-transmitting area 112 will be relatively uniform, and the brightness of the surroundings will be basically consistent, and the light effect will not be affected by the shadow caused by the obstruction of the reinforcing rib 111.

[0048] In some other specific embodiments, referring to Figure 4 Combination Figure 1 As shown, the outer cavity wall of the installation cavity 16 formed by the sealing connection between the cover plate 12 and the main body 11 may also be provided with a laminated recess 15 adapted to the thickness of the waterproof coating layer 14. By designing the laminated recess 15, when the waterproof coating layer 14 is formed on the outer cavity wall of the installation cavity 16 formed by the sealing connection between the cover plate 12 and the main body 11, the operation is more convenient and the thickness is easier to control.

[0049] In addition, the utility model also provides a children's toothbrush, referring to Figure 1-Figure 3As shown, it can specifically include a toothbrush handle 1 and a brush head 2 arranged on the toothbrush handle 1, and the toothbrush handle 1 is the toothbrush handle described in any of the above schemes. Since the above toothbrush handle has the above technical effects, the children's toothbrush with the toothbrush handle should also have corresponding technical effects, which will not be repeated here.

[0050] Of course, it is understandable that the application of the toothbrush handle 1 to a children's toothbrush is merely an example of an embodiment of the present invention. In actual application, it can also be applied to other types of toothbrushes, such as electric toothbrushes, etc. No further specific limitation is made on the application scenario here.

[0051] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
