Description

Technical Field

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

[0002] Currently, electric toothbrushes on the market are mainly divided into traditional rotary electric toothbrushes, sonic electric toothbrushes, and vibrating electric toothbrushes. Rotary electric toothbrushes typically use small, round brush heads to deeply clean teeth by rotating and rubbing around them, but this causes relatively more wear and tear on the toothbrush. Sonic electric toothbrushes use a motor to drive the bristles to vibrate at high speed, turning toothpaste and water into small bubbles and providing some friction to remove plaque and food debris. However, their cleaning ability is relatively weak, and they have difficulty reaching areas such as tooth sockets and gaps between teeth.

[0003] With technological advancements, the vibrating sweeping electric toothbrush has emerged, combining strong cleaning power with a better fit for the Bass brushing technique. The biggest difference between a vibrating sweeping electric toothbrush and a traditional electric toothbrush is that while only the bristles vibrate, the entire brush head of a vibrating sweeping electric toothbrush vibrates, simulating the up-and-down brushing motion, thus conforming to the Bass brushing technique and providing a more thorough cleaning. However, because the brush head of a vibrating sweeping electric toothbrush needs to vibrate, if the wireless receiver coil and the blue LED light of the novel practical blue light sonic electric toothbrush disclosed in patent document publication number 221083865U are suspended, the electrical connection stability between the receiver coil and the wireless receiver coil is difficult to guarantee during the brush head's sweeping motion, easily leading to the receiver coil detaching. Furthermore, currently, electric toothbrush heads and handles typically use a plug-in tight fit; when the brush head needs to sweep, the connection structure between the brush head and handle requires further improvement.

[0031] To more clearly illustrate the embodiments of this utility model, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0032] Example 1:

[0033] like Figures 1 to 6 As shown, the sweeping electric toothbrush of this embodiment includes a handle 1 and a brush head 2.

[0034] Specifically, the brush handle 1 is a frustum-shaped cylinder with a height of 8-15cm, featuring a larger outer diameter at the bottom and a smaller outer diameter at the top. Three evenly distributed facets 10 on its circumference form a grip surface, effectively improving grip stability and feel. The inner cavity of the brush handle 1 houses a main control circuit board 3, a sweeping motor 4, a battery 5, and a wireless transmitting coil 6a. The battery 5 powers the main control circuit board 3, which is connected to the sweeping motor 4 and the wireless transmitting coil 6a. Specific structural arrangements can be found in existing technologies and will not be elaborated here. Additionally, the brush handle 1 has a switch button 11 located on the arc surface between two adjacent facets, facilitating on / off operation while gripping the brush.

[0035] In this embodiment, the motor shaft of the sweeping motor 4 is connected to the linkage shaft 7, which extends beyond the brush handle 1 to facilitate a detachable drive connection with the brush head 2.

[0036] The brush head 2 of this embodiment includes a brush handle 21 and a bristle bundle 22 mounted on the top of the brush handle in a mounting slot. The bristle bundle 22 includes a transparent bristle patch 221 and bristles 222 arranged in an array on the transparent bristle patch. A blue LED light 8 is mounted on the wall of the mounting slot at the top of the brush handle. The light emitted by the blue LED light 8 is directed toward the bristle bundle 22 so that it can shine into the oral cavity through the bristle bundle 22. An adapter 9 is provided at the bottom of the brush handle 21, and the adapter 9 is detachably driven to the linkage shaft 7. In addition, a wireless receiving coil 6b is installed on the inner side of the bottom of the brush handle 21. The wireless receiving coil 6b is connected to the blue LED light 8 through a conductive wire, and the wireless receiving coil 6b is wirelessly transmitted to the wireless transmitting coil 6a.

[0037] In this embodiment, the adapter 9 has a convex structure, including a base 91 and a vertically extending column 92. The adapter 9 has an adapter hole 90 extending from the base to the height of the main body. The linkage shaft 7 is inserted into the adapter hole 90 to achieve a circumferential and axial limiting connection between the adapter and the linkage shaft. Specifically, the linkage shaft 7 has a first vertical plane 7a and a second vertical plane 7b on both sides. Correspondingly, the two side walls of the adapter hole 90 have a first plane and a second plane that respectively mate with the first vertical plane 7a and the second vertical plane 7b, thereby achieving a circumferential limiting connection between the adapter 9 and the linkage shaft 7, that is, achieving synchronous rotation between the adapter 9 and the linkage shaft 7. In addition, the adapter 9 has a flexible snap-fit ​​connector 9c, and correspondingly, the linkage shaft 7 has a slot 7c. When the linkage shaft 7 is inserted into the adapter hole 90, the flexible snap-fit ​​connector 9c and the slot 7c engage to achieve axial limiting connection between the adapter 9 and the linkage shaft 7. When the brush head 2 needs to be pulled out of the brush handle 1, the flexible snap-fit ​​connector 9c disengages from the slot 7c under the action of external force, and the brush head 2 can be pulled out.

[0038] In this embodiment, the outer wall of the column 92 has a vertically extending wiring channel I for the routing of conductive wires. The wiring channel I includes a first inclined segment I1, a vertical segment I2, and a second inclined segment I3 connected in sequence. The free end of the first inclined segment I1 (i.e., the top of the wiring channel I) is located inside the vertical segment I2 and communicates with the wire outlet 920 at the top of the column. The free end of the second inclined segment I3 (i.e., the bottom of the wiring channel I) is located outside the vertical segment I2 and is adjacent to the base 91. In this embodiment, the elastic snap-fit ​​connector 9c is located directly below the free end of the second inclined segment I3, and the periphery of the elastic snap-fit ​​connector 9c is hollowed out to ensure its elastic movement space. The design of the wiring channel I in this embodiment can prevent the conductive wires from easily detaching from the wireless receiving coil during the brush head 2's sweeping motion, effectively improving the working stability of the vibrating electric toothbrush.

[0039] In this embodiment, the wireless receiving coil 6b is confined within the brush rod 21 via an adapter 9. Specifically, the wireless receiving coil 6b is sleeved outside the column 92 and abuts against the base 91. The base 91 has two coil fixing lugs 910, which are evenly distributed along the circumference of the base 91 for fixing the wireless receiving coil 6b. In addition, the inner sidewall of the brush rod 21 has a limiting protrusion 210, which abuts against the wireless receiving coil 6b to prevent axial movement of the wireless receiving coil 6b.

[0040] In this embodiment, the brush handle 21 is provided with a soft rubber sleeve T at the top, which reduces vibration and improves comfort when in contact with the teeth.

[0041] In this embodiment, the oscillation angle range of the brush head 2 is 60°, that is, the brush head can oscillate 30° to the left and right, which conforms to the Bass brushing technique and improves the teeth cleaning effect.

[0042] Example 2:

[0043] The difference between the sweeping electric toothbrush in this embodiment and that in embodiment 1 is:

[0044] The linkage shaft is a square shaft, and correspondingly, the adapter hole is a square hole, which can also realize the circumferential limiting connection between the adapter and the linkage shaft to meet the needs of different applications;

[0045] Other structures can be found in Example 1.

[0046] Example 3:

[0047] The difference between the sweeping electric toothbrush in this embodiment and that in embodiment 1 is:

[0048] The brush head can swing at an angle of up to 30°, meaning it can swing 15° to the left and right; or it can swing at an angle of up to 40°, meaning it can swing 20° to the left and right, to meet the needs of different applications.

[0049] Other structures can be found in Example 1.

[0050] It should be noted that the above embodiments can be freely combined as needed. The above description is only a detailed explanation of the preferred embodiments and principles of this utility model. For those skilled in the art, there will be changes in the specific implementation methods based on the ideas provided by this utility model, and these changes should also be considered within the protection scope of this utility model.
