Description

Technical Field

[0001] This utility model belongs to the field of electric toothbrush technology, specifically relating to an electric toothbrush with a protective cover. Background Technology

[0002] In recent years, the popularity of electric toothbrushes in the Chinese market has increased significantly, and they have gradually become a daily necessity for many families, transforming from a niche product. Their designs are not only stylish and diverse with rich colors, but also exquisitely crafted, satisfying the dual demands of consumers of different ages for both functionality and aesthetics.

[0003] After using an electric toothbrush to clean their teeth, people usually put it back in the cup for the next use. However, due to the relatively enclosed environment of the bathroom, microorganisms such as bacteria, mold, and viruses are more likely to float in such an environment. Both electric and traditional toothbrushes may face similar hygiene challenges. Although some electric toothbrush manufacturers offer protective covers to protect the brush head, these covers are designed as separate parts for easy removal of the brush head, making them easy to lose during daily use. After oral cleaning, if the protective cover is placed directly on the brush head, it may come into contact with the bristles, causing contamination.

[0004] Therefore, optimizing the design of the protective cover on existing electric toothbrushes to make it less likely to be lost and to effectively isolate microorganisms, ensuring the cleanliness of the brush head, while also preventing it from coming into contact with the bristles during use to avoid secondary contamination, became the primary task of this product development. Utility Model Content

[0005] To address the problems of existing electric toothbrush packaging including a protective cover that is easily lost and poses a potential risk of contamination, this invention provides an electric toothbrush with a protective cover.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electric toothbrush with a protective cover, comprising an electric handle and a detachable brush head, a housing is provided on the electric handle, a connecting rod is slidably provided on the housing, a protective cover is provided at the upper end of the connecting rod, the protective cover comprises a cover plate and two side plates, the cover plate and the two side plates are respectively mounted on the connecting rod via a rotating shaft, the two side plates are located on the lower sides of the cover plate, torsion springs are respectively provided on the rotating shafts of the cover plate and the two side plates, and the three together, under the action of the torsion springs, push upward to form a protective space for placing the brush head.

[0007] As a further supplement to the above technical solution, a vertical guide hole is provided on the outer shell, and a T-key is installed at the lower end of the connecting rod. The T-key is movably disposed in the vertical guide hole to form a sliding structure.

[0008] As a further explanation and limitation of the above technical solution, limit grooves are respectively provided at both ends of the vertical guide hole, and the T-key is locked in position by sliding up and down into the limit groove.

[0009] As a further explanation and limitation of the above technical solution, a stop spring is provided between the T-key and the connecting rod. Under the action of the stop spring, the T-key is embedded in the limiting groove and the connecting rod slides up and down by being pulled outward.

[0010] As a further supplement to the above technical solution, a reserved hole is provided on the outer shell, which facilitates touching the operation buttons of the electric handle through the outer shell.

[0011] As a further supplement to the above technical solution, a frustum-shaped inclined surface is provided on the electric handle, which facilitates the separation of the two side plates and their retraction into the outer shell when the protective cover moves downward.

[0012] As a further supplement to the above technical solution, a disinfection component is installed on the inner side of the two side plates, which is used to disinfect and sterilize the brush head.

[0013] As a further explanation and limitation of the above technical solution, the disinfection component includes a lamp panel, ultraviolet lamp beads, a switch and a button battery. The lamp panel is mounted on a side plate, the ultraviolet lamp beads are mounted on the lamp panel and are electrically connected to the button battery through the switch. The switch and the button battery are mounted on the outer wall of the connecting rod.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This utility model features a deformable protective cover that slides onto the electric handle. When the electric toothbrush is not in use, this cover creates a barrier around the brush head, effectively preventing bacteria floating in the bathroom from adhering to the brush head, thus improving the hygiene performance of the electric toothbrush. Simultaneously, because the cover is supported by a connecting rod, it does not come into contact with the bristles, preventing contamination and ensuring the cleanliness of the brush head.

[0016] 2. This utility model incorporates a disinfection component on the protective cover. This disinfection component uses evenly distributed ultraviolet lamp beads to achieve all-around disinfection of the brush head. Furthermore, the disinfection component can be stored inside the outer casing along with the protective cover, saving space and simplifying user operation.

[0017] 3. This utility model ensures that the protective cover is securely locked by the cooperation of the T-shaped key and the limiting groove, preventing accidental opening and enhancing the safety of use.

Detailed Implementation

[0028] To further illustrate the technical solution of this utility model, the following description is in conjunction with the appendix. Figures 1 to 7 The present invention will be further described in detail through five embodiments. Example

[0029] As attached Figures 1 to 5As shown, an electric toothbrush with a protective cover includes an electric handle 1 and a detachable brush head 2. A housing 3 is mounted on the electric handle 1, and a connecting rod 4 is slidably mounted on the housing 3. A protective cover 5 is mounted on the upper end of the connecting rod 4. The protective cover 5 includes a cover plate 501 and two side plates 502. The cover plate 501 and the two side plates 502 are respectively mounted on the connecting rod 4 via rotating shafts. The two side plates 502 are located on the lower sides of the cover plate 501. Torsion springs 503 are respectively mounted on the rotating shafts of the cover plate 501 and the two side plates 502. Under the action of the torsion springs 503, the cover plate 501 and the two side plates 502 push upwards to form a protective space for holding the brush head 2. The preload of the torsion springs 503 ensures that the protective cover 5 is securely closed, preventing the brush head 2 from accidentally falling off. The sliding design of the connecting rod 4 allows the protective cover 5 to be easily unfolded or retracted, making operation simple.

[0030] In practical use, as shown in the attached document Figure 3 As shown, a vertical guide hole 301 is provided on the outer casing 3, and a T-key 6 is installed at the lower end of the connecting rod 4. The T-key 6 is movably disposed within the vertical guide hole 301 to form a sliding structure. The stop spring 601 of the T-key 6 ensures its stability during sliding and prevents accidental operation. Example

[0031] To determine the position of connecting rod 4 in vertical guide hole 301, see attached... Figure 3 and attached Figure 4 As shown, based on the above design, we set limiting grooves 302 at both ends of the vertical guide hole 301. The T-key 6 is locked in position by sliding up and down into the limiting groove 302. At the same time, a stop spring 601 is set between the T-key 6 and the connecting rod 4. Under the action of the stop spring 601, the T-key 6 is embedded into the limiting groove 302 and drives the connecting rod 4 to slide up and down by pulling it outward. Example

[0032] For easier operation of the electric handle 1, see attached... Figure 5 As shown, a pre-drilled hole 303 is provided on the outer casing 3, which facilitates touching the operation buttons of the electric handle 1 through the outer casing 3. The design of the pre-drilled hole 303 not only improves the ease of operation but also ensures the waterproof performance of the electric handle 1. Example

[0033] To ensure that the protective shield 5 can open automatically when it retracts, see attached... Figure 5As shown, we designed the electric handle 1 as a frustum 7. This optimized design facilitates the separation and retraction of the two side plates 502 into the outer shell 3 when the protective cover 5 moves downwards. When the protective cover 5 is fully extended, the slope of the frustum 7 causes the side plates 502 to automatically flip outwards, forming a stable protective space. After the brush head 2 is installed, the closing action of the protective cover 5 is driven by a torsion spring 503, ensuring the stability of the brush head 2. Example

[0034] To further enhance the protection of brush head 2, as shown in the attached document... Figure 6 and attached Figure 7 As shown, a disinfection assembly 8 is installed on the inner side of the two side panels 502. The disinfection assembly 8 includes a lamp panel 801, ultraviolet lamp beads 802, a switch 803, and a button battery 804. The lamp panel 801 is mounted on the side panel 502, and the ultraviolet lamp beads 802 are mounted on the lamp panel 801. The lamp beads 802 are electrically connected to the button battery 804 via the switch 803. The switch 803 and the button battery 804 are mounted on the outer wall of the connecting rod 4. When the protective cover 5 is closed, the ultraviolet lamp beads 802 automatically activate, efficiently disinfecting the brush head 2 to ensure hygienic use. The switch 803 is designed for easy operation, and the button battery 804 provides continuous power, ensuring the sustained effectiveness of the disinfection function.

[0035] Its specific usage:

[0036] Before brushing, the user turns on the UV lamp 802 via switch 803, using its irradiation function to effectively disinfect and sterilize the brush head 2 for approximately several tens of seconds, then turns off the UV lamp 802. Next, the user pulls the T-shaped button 6 out of the limiting groove 302 and slides it downwards along the vertical guide hole 301. During the sliding process, the cover plate 501 is lifted by the brush head 2, and the side plate 502 is pushed outwards by the truncated cone inclined surface 7 until the T-shaped button 6 slides into another limiting groove 302. At this point, the T-shaped button 6 is pulled by the stop spring 601 and automatically inserts into the limiting groove 302.

[0037] After brushing, pull the T-key 6 out of the limiting groove 302 again and slide it upward along the vertical guide hole 301. This will cause the connecting rod 4 to move the protective cover 5 out of the outer shell 3. When the T-key 6 slides to another limiting groove 302, the force of the torsion spring 503 causes the cover plate 501 and the two side plates 502 to close, forming a safe protective space for placing the brush head 2.
