Description

Technical Field

[0001] This utility model relates to the field of electric toothbrush technology, and in particular to a vibration-damping electric toothbrush. Background Technology

[0002] Toothbrushes are the most commonly used dental hygiene tool, used to remove bacteria, plaque, and small debris attached to teeth. They play a role in preventing periodontal disease and protecting oral hygiene and dental health. There are many types of toothbrushes on the market, including electric toothbrushes. Compared to regular toothbrushes, electric toothbrushes are more scientifically effective in removing plaque and reducing oral diseases such as gingivitis, periodontal disease, and bleeding gums, making them popular.

[0003] Most electric toothbrushes currently on the market operate on a vibration principle. These toothbrushes use a rapidly rotating or vibrating motor to create high-frequency vibrations in the brush head, instantly breaking down toothpaste into fine foam that deeply cleans between teeth. At the same time, the vibrations of the bristles promote blood circulation in the mouth and have a massaging effect on the gum tissue.

[0004] To achieve better cleaning results, existing electric toothbrushes have a vibration frequency of over 30,000 times per minute. Due to the high-speed operation of the motor in the electric toothbrush, the body and shell of the toothbrush vibrate considerably. Frequent vibration can easily cause parts of the electric toothbrush to fall off, affecting the lifespan of the parts. At the same time, frequent vibration can also affect the user experience.

[0005] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0032] To illustrate the technical solution described in this utility model, specific embodiments are described below, showing only the parts related to the embodiments of this utility model.

[0033] Example:

[0034] like Figure 1-3As shown, this utility model provides a vibration-damping electric toothbrush, including: a toothbrush body 1 and a toothbrush head 2 detachably connected to the toothbrush body 1; the toothbrush body 1 includes a shell 3, a charging component 4, a battery component 5, a motor component 6, and a body support 7; the body support 7 is internally divided into a first accommodating area 73, a second accommodating area 74, and a third accommodating area 75 by a first partition 71 and a second partition 72, and the charging component 4, the battery component 5, and the motor component 6 are respectively placed in the first accommodating area 73, the second accommodating area 74, and the third accommodating area 75; the motor component 6 includes a motor 61 and a wrapping component 62, and the motor 61 is placed in the third accommodating area 75 after being wrapped by the wrapping component 62.

[0035] Specifically, such as Figure 2-3 As shown, the toothbrush body 1 includes a body support 7. The body support 7 is internally divided by a first partition 71 and a second partition 72, forming a first accommodating area 73, a second accommodating area 74, and a third accommodating area 75. These areas provide space for the charging component 4, the battery component 5, and the motor component 6. Simultaneously, the separation of the charging component 4, the battery component 5, and the motor component 6 by the first partition 71 and the second partition 72 in the body support 7 reduces resonance experienced by each component during operation, thus extending their lifespan. The separation of the charging component 4, the battery component 5, and the motor component 6 from the housing 3 by the body support 7 reduces resonance experienced by the housing, improving the user experience. The partitioning of the body support 7 facilitates the placement of the charging component 4, the battery component 5, and the motor component 6, saves internal space in the housing 3, and optimizes the internal structure.

[0036] It should be noted that a portion of the sidewalls of the first accommodating area 73, the second accommodating area 74, and the third accommodating area 75 of the fuselage support 7 is configured as an elastic structure 76 for vibration damping. In this embodiment, the fuselage support 7 can be made of silicone or rubber.

[0037] In addition, such as Figure 4 As shown, the motor assembly 6 includes a motor 61 and a housing 62. The motor 61 is enclosed by the housing 62 before being placed in the third receiving area 75 of the body bracket 7. It should be noted that the motor 61, as the driving component of the electric toothbrush, will rotate or vibrate rapidly during operation, causing the toothbrush head 2 to vibrate at high frequency. Therefore, the housing 62, which encloses the motor 61, before placing it in the third receiving area 75 of the body bracket 7. This reduces the impact of the motor 61's vibration on other components and significantly reduces resonance experienced by other components and the housing 3.

[0038] Below, we will combine Figure 1-5The vibration-damping electric toothbrush described in this embodiment will be explained in detail.

[0039] As an optional implementation method, such as Figure 4 As shown, the wrapping component 62 includes a rubber coating 63, a rubber coating cover 64, and a bushing 65. The rubber coating 63 and the rubber coating cover 64 cooperate to wrap the motor 61, and the bushing 65 is used to wrap the output shaft 611 of the motor 61. The function of the wrapping component 62 is to wrap the motor 61 and place it in the third receiving area 75 of the body bracket 7 after wrapping.

[0040] The enclosure 62 includes an overlay 63, an overlay cover 64, and a bushing 65. The overlay 63 is a cavity with one open end, into which the motor 61 can be placed. An opening (not shown in the figure) is provided on the side of the overlay 63 corresponding to the opening, which facilitates the electrical connection of the motor 61 with other components, such as the connection of the motor 61 with the battery assembly 5 and the control assembly 8.

[0041] The rubber-coated cap 64 is also a cavity with an open end. The opening of the rubber-coated cap 64 can contact and cooperate with the opening of the rubber-coated cap 63 to completely enclose the motor 61, thereby reducing the outward vibration generated by the motor 61 during operation. A hole 641 is provided on the side of the rubber-coated cap 64 corresponding to the opening. This hole 641 facilitates the installation of the output shaft 611 of the motor 61, allowing the output shaft 611 to extend outward through the through hole. It should be noted that a connecting shaft 612 is also provided on the output shaft 611, which facilitates the subsequent connection of the toothbrush head 2.

[0042] The bushing 65 is located on the side of the rubber cover 64 with the hole 641 and is fixedly connected to the rubber cover 64. The bushing 65 has a central hole 651 along the central axis, through which the output shaft 611 of the motor 61 can pass. The bushing 65 is used to protect the output shaft 611; at the same time, it can also reduce the vibration of the output shaft 611 during operation and reduce the resonance of the housing 3.

[0043] It should be noted that, as Figure 4 As shown, the bushing 65 is stepped. Specifically, the outer wall of the bushing 65 is stepped in the axial direction. The bushing 65 starts at one end near the motor 61 and ends at the other end, arranged from high to low. This stepped design of the bushing 65 helps to waterproof the motor 61, preventing water from entering the housing 3 and affecting the normal operation of the motor 61. In this embodiment, the bushing 65 has three steps.

[0044] As an optional implementation method, such as Figure 2As shown, the toothbrush body 1 also includes a control component 8, with the battery component 5 and motor component 6 both connected to the control component 8. The control component 8 is located inside the housing 3 and connected to the outer wall of the body support 7. Specifically, the control component 8 is connected to the battery component 5 and the motor component 6 respectively, and is used to control the battery component 5 and the motor component 6, control the motor component 6 to start, control the battery component 5 to supply power to the motor component 6, and uniformly control the corresponding components inside the toothbrush body 1, thereby improving its integration level.

[0045] like Figure 2 As shown, the control component 8 is provided with a pressure sensing area 81, and a conductive silicone 82 is provided on the pressure sensing area 81. The pressure sensing area 81 is correspondingly set with the touch area 31 on the housing 3 through the conductive silicone 82. Specifically, the pressure sensing area 81 on the control component 8 is actually a button structure. The user can control the electric toothbrush by pressing or touching the pressure sensing area 81, making it easy to switch the working mode of the electric toothbrush. The setting of the pressure sensing area 81 makes the control more sensitive and the operation simpler.

[0046] As an optional implementation method, such as Figure 5 As shown, the charging component 4 includes a charging female connector 41 and a waterproof seat 42. The waterproof seat 42 is located at the charging port end of the charging female connector 41 and is fixedly connected to the charging female connector 41. Specifically, the charging component 4 is electrically connected to the battery component 5 and can be connected to an external power supply to charge the battery component 5 in the toothbrush body 1. The charging component 4 includes a charging female connector 41 and a waterproof seat 42. The charging female connector 41 is the component that actually connects to the external power supply, and the waterproof seat 42 is located at the charging port end of the charging female connector 41 to provide waterproof protection for the charging female connector 41.

[0047] like Figure 5 As shown, the waterproof base 42 includes a waterproof body 421, waterproof protrusions 422, and a waterproof ring 423. Two waterproof protrusions 422 are provided, arranged circumferentially around the waterproof body 421 with a gap between them. The waterproof ring 423 is located within the gap formed by the two waterproof protrusions 422. Specifically, the waterproof base 42 is used to provide waterproof protection for the charging female connector 41. The waterproof base 42 includes a waterproof body 421, waterproof protrusions 422, and a waterproof ring 423. The waterproof body 421 is directly connected to the charging female connector 41. Two waterproof protrusions 422 are provided, arranged circumferentially around the waterproof body 421, with a gap between them large enough to accommodate the waterproof ring 423. The waterproof ring 423 provides further waterproofing. Even if the electric toothbrush is in a wet environment, the waterproof base 42 can still provide waterproof protection for the charging interface, preventing water from entering the charging interface and also preventing water from entering the interior of the housing 3.

[0048] It should be noted that, as Figure 2 As shown, a bottom shell 32 is provided at the end of the housing 3 that contacts the charging assembly 4, and the bottom shell 32 is connected to the waterproof seat 42 in the charging assembly 4. A waterproof cover (not shown in the figure) is provided at the very end of the bottom shell 32. The waterproof cover can be opened to expose the charging female seat 41, which facilitates the connection of the charging female seat 41 to an external power supply, allowing the battery assembly 5 to be charged. The bottom shell 32 provides waterproof protection for all components inside the housing 3, preventing water from entering the interior of the housing 3.

[0049] As an optional implementation method, such as Figure 2 As shown, the toothbrush head 2 is detachably connected to the toothbrush body 1. The toothbrush head 2 includes a connecting part 21 and a brush head 22. The connecting part 21 is detachably connected to the motor assembly 6, and the connecting part 21 and the brush head 22 are integrally connected. Specifically, a connecting shaft 612 is provided on the output shaft 611 of the motor 61. The connecting part 21 of the toothbrush head 2 is detachably connected to the connecting shaft 612. The connecting part 21 allows the toothbrush head 2 to be installed on the output shaft 611 and connected to the toothbrush body 1 to form an electric toothbrush; it also allows the toothbrush head 2 to be removed from the output shaft 611 and disconnected from the toothbrush body 1 for replacement or cleaning. The brush head 22 of the toothbrush head 2 and the connecting part 21 are an integral structure, and the brush head 22 can clean teeth.

[0050] The toothbrush head 2 has a bristle surface on one side and a soft rubber surface on the other. This soft rubber surface helps prevent teeth from hitting the user's teeth during electric toothbrush use, protecting teeth and enhancing the user experience.

[0051] The vibration-damping electric toothbrush described in this embodiment includes a body support 7, which is housed within the casing 3. The charging component 4, battery component 5, and motor component 6 are respectively housed within the first accommodating area 73, the second accommodating area 74, and the third accommodating area 75 of the body support 7. Furthermore, the motor component 6 includes a wrapping component 62, which can wrap the motor 61 before placing it within the third accommodating area 75. The design of the body support 7 and the wrapping component 62 can significantly reduce the resonance experienced by the various components and the casing 3, resulting in a strong vibration damping effect. This not only improves the service life of the various components but also enhances the user experience.

[0052] The embodiment is merely a special case and does not indicate that this utility model is implemented in such a way.

[0053] The above description is merely a preferred embodiment of the present utility model.
