Description

Technical Field

[0001] The invention relates to the technical field of electric toothbrushes, and in particular to a retractable ultraviolet sterilization brush head cover for an electric toothbrush. Background Art

[0002] Electric toothbrushes are new products that have appeared in recent years and have set off a revolution in the field of oral health care abroad. Although the application of electric toothbrushes in China is not yet popular, some people have predicted that it will become an important member of public health products.

[0003] The electric toothbrushes currently on the market clean their brush heads in the same way as traditional manual toothbrushes, i.e., rinse with water, shake off the water droplets on the surface, and place in a mouthwash cup, but the brush head is still wet. The interval between brushing teeth twice a day, morning and evening, is often as long as 12 hours, and the brush head becomes a hotbed for bacterial growth, which will breed a large number of harmful bacteria and endanger the health of users.

[0004] Some electric toothbrushes on the market also provide a split sterilization structure, but the split part needs to be powered separately, which is inconvenient to use and not easy to carry. Therefore, some users abandon the sterilization part because it is cumbersome to use. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a retractable ultraviolet sterilization brush head cover for an electric toothbrush.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A retractable ultraviolet sterilization brush head cover for an electric toothbrush comprises a brush head cover, two sliding rods, a sterilization circuit board, a sterilization lamp, a scene indicator light and a spring electrode. One end of the two sliding rods is fixed inside the brush head cover, and the other end of the two sliding rods is inserted into the shaft sleeve of the mounting frame in the brush handle, so that the brush head cover can perform telescopic movement relative to the mounting frame. The sterilization circuit board is arranged inside the brush head cover, one end of the sliding rod is connected to the sterilization circuit board through spring electrodes, and the sterilization lamp and scene indicator light are arranged on the sterilization circuit board.

[0008] Preferably, a slot is provided inside the brush head cover, and the sterilization circuit board is installed in the slot.

[0009] Preferably, the sterilization circuit board is coated with a silica gel layer.

[0010] Preferably, the brush head cover is made of plastic material, one end of the sliding rod and the spring electrode are injection-molded with the brush head cover to form an integrated structure, and the other end of the spring electrode is welded to the sterilization circuit board.

[0011] Preferably, a limiting member is also fixed to one end of the sliding rod inserted into the shaft sleeve.

[0012] Preferably, the sliding rod and the limiting member are both made of metal.

[0013] Compared with the existing technology, the beneficial effect of the present invention is: by combining one end of the two sliding rods with the brush handle, and the other end of the sliding rods with the sterilization circuit board, the purpose of controlling the sterilization lamp to sterilize the toothbrush head is achieved, and it can be conveniently combined with the brush handle into a complete product, so that the toothbrush can both brush teeth and have a sterilization effect.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] like Figure 1-4 As shown, a retractable ultraviolet sterilization brush head cover for an electric toothbrush includes a brush head cover 1, two sliding rods 2, a sterilization circuit board 3, a sterilization lamp 4, a scene indicator light 5 and a spring electrode 6.

[0020] One end of the two slide bars 2 is fixed inside the brush head cover 1, one end of the spring electrode 6 is wound around the slide bar 2, and the other end of the spring electrode 6 is welded to the sterilization circuit board 3. In this embodiment, the brush head cover 1 is made of plastic, and one end of the slide bar 2 and the spring electrode 6 are injection molded with the brush head cover 1 to form an integrated structure. A slot (not shown) is provided inside the brush head cover 1, and the sterilization circuit board 3 is installed in the slot. The sterilization lamp 4 and the scene indicator light 5 are provided on the sterilization circuit board 3, and silicone is dotted on the sterilization circuit board 3, which plays both a fixing role and a waterproof role.

[0021] The other ends of the two slide bars 2 are inserted into the shaft sleeves 9 of the mounting frame 8 in the brush handle, so that the brush head cover 1 can telescopically move relative to the mounting frame 8, and the end of the slide bar 2 inserted into the shaft sleeve 9 is also fixed with a limiting member 7. In this embodiment, the slide bar 2 and the limiting member 7 are both made of metal, so that the slide bar 2 plays both a supporting role and a conductive role.

[0022] The retractable ultraviolet sterilization brush head cover of this embodiment, when it retracts into the inside of the brush handle, the brush head cover 1 is separated from the toothbrush head, and the electric toothbrush is the same as an ordinary toothbrush; when the brush head cover is manually pulled out, the brush head cover 1 is outside the brush head, and the limiter 7 at one end of the slide rod 2 will contact the circuit board 10 fixed on the mounting frame 8. There are also two elastic electrodes 11 on the circuit board 10. At this time, the two elastic electrodes 11 are tightly combined with one end of the metal slide rod 2, and the circuit board 10 is connected to the external battery, so that the sterilization circuit board 3 in the toothbrush cover 1 is powered through the slide rod 2. At this time, the sterilization lamp 4 starts to work to sterilize the brush head. During the sterilization, the scene indicator light 5 lights up to indicate the working status.

[0023] In the description of this utility, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility can be understood according to specific circumstances.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
