Description

Technical Field

[0001] This application belongs to the field of electric toothbrush technology and relates to an electric toothbrush with a rotating brush head and a vibrating brush head. Background Technology

[0002] Currently, electric toothbrushes are mainly divided into two categories: sonic vibration type and rotary type. The two differ significantly in their cleaning principles, brush head design, and motor drive methods.

[0003] Sonic electric toothbrushes: These use high-frequency vibrations to drive the brush head to oscillate from side to side, utilizing hydrodynamics to clean the tooth surface and between teeth. Their brush head interfaces are typically flat or snap-on designs, suitable for transmitting high-frequency vibrations.

[0004] Rotary electric toothbrushes: These use a motor to drive the brush head in a circular motion or oscillate from side to side, using mechanical friction to clean the tooth surface. Their brush head interfaces are typically circular or have a drive shaft design, suitable for transmitting rotary motion.

[0005] Because the two technologies differ in their driving methods and interface designs, existing electric toothbrushes are generally incompatible with both vibrating and rotating brush heads. Users who wish to experience different cleaning modes must purchase multiple electric toothbrushes, increasing both cost and inconvenience.

[0006] Therefore, how to provide an electric toothbrush with both rotating and vibrating brush heads, while being compatible with both, has become an urgent technical problem to be solved. Utility Model Content

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0044] This embodiment discloses an electric toothbrush with a rotating brush head and a vibrating brush head, such as... Figures 1-8 As shown, it includes:

[0045] The toothbrush body 1 is provided with a rotating shaft 11. A shaft 12 is provided on the outside of the rotating shaft 11, and a space for movement is reserved between the shaft 12 and the rotating shaft 11. The shaft 12 is used to connect the rotating brush head 2 and the vibrating brush head 3.

[0046] The rotating brush head 2 includes a first connector 21, a transmission assembly, a first brush rod 23, and a brush disc 24 with bristles;

[0047] The vibrating brush head 3 includes a second connector 31 and a second brush rod 32 with bristles.

[0048] It should be noted that the rotating shaft 11 and the shaft 12 can be connected to the rotating brush head 2 and the vibrating brush head 3 respectively, so that the electric toothbrush is compatible with two different types of brush heads at the same time. That is, the rotating shaft 11 can be connected to the connecting rod 22 provided on the rotating brush head 2 and the second connecting member 31 provided on the vibrating brush head 3 respectively, and the shaft 12 can be connected to the first connecting member 21 to form a connection relationship with the rotating brush head 2. There is a movable gap between the shaft 12 and the second brush rod 32, which can avoid affecting the vibration of the vibrating brush head 3.

[0049] Meanwhile, during operation, the rotating shaft 11 can drive the connecting rod 22 to swing inside the first brush rod 23, which in turn drives the mounting block 2 on the brush plate 24 to reciprocate and rotate, thus rotating the brush head. The shaft 12 is connected to the first connecting member 21, which can maintain the positional relationship between the first connecting member 21 and the first brush rod 23 relative to the toothbrush body 1. When connected to the vibrating brush head 3, the rotating shaft 11 directly drives the second brush rod 32 to swing through the second connecting member 31, thus vibrating the brush head.

[0050] like Figure 4 As shown, the outer circumferential surface of the shaft 12 is provided with four outwardly protruding curved surfaces, which extend radially along the shaft 12 and form a cuboid structure;

[0051] One of the curved surfaces has an axially extending groove.

[0052] By providing protrusions corresponding to the groove structure inside the first connector 21, the shaft 12 and the first connector 21 can be fixed and limited.

[0053] like Figure 6 and Figure 7 As shown, the first connecting member 21 has a first mounting cavity 2101 inside that corresponds to the shape of the shaft 12 and penetrates through the top wall, and a baffle plate 2102 is provided on the outside of the top wall;

[0054] The first connector 21 is snapped onto the outside of the shaft 12 through the first mounting cavity 2101.

[0055] like Figure 1 and Figure 6 As shown, the transmission component is a connecting rod 22. The first end of the connecting rod 22 is provided with a protrusion 2201, and the second end of the connecting rod 22 is provided with a rotating shaft 2202.

[0056] The connecting rod 22 abuts against the outside of the top wall, and the baffle plate 2102 is used to limit the rotational stroke of the protrusion 2201.

[0057] like Figure 1 and Figure 5 As shown, the first brush rod 23 has a second mounting cavity 2301 that extends through both ends, and the second mounting cavity 2301 has a mounting platform 2302 inside;

[0058] The first connector 21 is embedded inside the second mounting cavity 2301;

[0059] The connecting rod 22 is installed inside the second mounting cavity 2301, and the connecting rod 22 can swing relative to the first brush rod 23;

[0060] like Figure 1 and Figure 6 As shown, a mounting block 2401 is provided on the side of the brush disk 24 away from the bristles;

[0061] The brush plate 24 is installed inside the second mounting cavity 2301 via the mounting block 2401. When the connecting rod 22 swings, it drives the brush plate 24 to reciprocate and rotate by squeezing the mounting block 2401.

[0062] It should be noted that the rotating brush head 3 is connected to the toothbrush body 1 through the first connector 21 and the connecting rod 22. The first brush rod 23 serves as the outer shell, which can fix the first connector 21, fix the position of the connecting rod 22 and allow it to swing, and fix the position of the brush plate 24 and allow it to reciprocate through the connecting rod 22.

[0063] like Figure 8 As shown, the first end of the second connector 31 is provided with a fixing ring 3101, and the second end of the second connector 31 is provided with a cross protrusion 3102.

[0064] It should be noted that the retaining ring 3101 abuts against the side wall formed at the connection between the third mounting cavity 3201 and the fourth mounting cavity 3202 to form a limit between the second connector 31 and the second brush rod 32.

[0065] like Figure 8 As shown, the second brush rod 32 has a third mounting cavity 3201 and a fourth mounting cavity 3202 arranged in sequence inside. The third mounting cavity 3201 has four spring arms 3203 evenly arranged in the circumferential direction inside.

[0066] The second brush rod 32 is sleeved on the outside of the shaft 12 through the fourth mounting cavity 3202;

[0067] A certain distance is reserved between two adjacent spring arms 3203 to form a cross groove.

[0068] It should be noted that after the cross protrusion 3102 is inserted into the "+" groove, it can cause the second connector 31 to drive the second brush rod 32 to vibrate.

[0069] like Figure 1 and Figure 8 As shown, the second connector 31 is inserted into the "+" groove through the cross protrusion 3102 to form an interference fit.

[0070] It should be noted that the spring arm 3203 is fixedly connected to the second brush rod 32, or only one end of the spring arm 3203 is fixedly connected to the second brush rod 32.

[0071] like Figures 1-8 As shown, both the connecting rod 22 and the second connecting member 31 are provided with a snap-fit ​​structure at their connection ends with the rotating shaft 11, and the connecting rod 22 and the second connecting member 31 are connected to the rotating shaft 11 through the snap-fit ​​structure.

[0072] It should be noted that the snap-fit ​​structure is existing technology.

[0073] Working principle: The rotating shaft 11 and the shaft 12 can be connected to the rotating brush head 2 and the vibrating brush head 3 respectively, so that the electric toothbrush is compatible with two different types of brush heads at the same time. That is, the rotating shaft 11 can be connected to the connecting rod 22 set in the rotating brush head 2 and the second connecting piece 31 set in the vibrating brush head 3 respectively to form a connection relationship with the rotating brush head 2 and the vibrating brush head 3. The shaft 12 can be connected to the first connecting piece 21 to form a connection relationship with the rotating brush head 2. This can adapt to the brushing habits of different people and improve the universality of the electric toothbrush.
