[0043] Toothbrushes are essential in people's daily lives. With the development of science and technology and the improvement of people's living standards, the use of electric toothbrushes is becoming more and more common. When people travel or go on business trips, they often have to carry toothbrushes, toothpaste and other essential cleaning supplies. However, the toothbrushes in the prior art are all in the shape of long strips, which makes them long and inconvenient to carry. For this reason, the related art equips the electric toothbrush with a storage box, and the user can disassemble the toothbrush head and then use the storage box to store the toothbrush body and the toothbrush head. However, although this solution solves the problem in the length direction, the storage box is usually large in size and takes up a large space, which is not conducive to carrying.

[0044] Based on the above problems, the present utility model embodiment proposes an electric toothbrush, referring to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an electric toothbrush according to an embodiment of the utility model. Figure 2 for Figure 1 The electric toothbrush in this embodiment includes a toothbrush handle 100, a clamping member 200 and a toothbrush head 400.

[0045] The clamping member 200 can be integrally processed with the toothbrush handle 100, or can be connected to the side of the toothbrush handle 100 by screw connection, plug connection or adhesive connection, etc. The clamping member 200 has a clamping slot 210 and a clamping port 220 connected to the clamping slot 210. The toothbrush head 400 is detachably connected to the toothbrush handle 100 by plugging or threading, and the toothbrush head 400 can extend from the clamping port 220 into the clamping slot 210 and be clamped in the clamping slot 210. The length of the toothbrush head 400 is not greater than the length of the toothbrush handle 100. Therefore, when the toothbrush head 400 is clamped to the side of the toothbrush handle 100, both ends of the toothbrush head 400 do not protrude from the end of the toothbrush handle 100. For example, the toothbrush handle 100 includes a connecting handle 410 and bristles 420. One end of the connecting handle 410 has a plug hole 411, and the other end is connected to the bristles 420. One end of the toothbrush handle 100 has a connector 300. The plug hole 411 is used to plug and match with the connector 300 to achieve a detachable connection of the toothbrush head 400. After the connecting handle 410 is removed from the connector 300, it can be snapped into the slot 210. Specifically, when in use, the user plugs the connecting handle 410 into the connector 300, and the motor 600 inside the toothbrush handle 100 drives the connector 300 to drive the toothbrush head 400 to move, thereby achieving the purpose of cleaning teeth. When storing, the user removes the toothbrush head 400 from the connecting piece 300 and extends the connecting handle 410 from the bayonet 220 into the slot 210. It can be understood that the electric toothbrush of this embodiment can use its own structure to store the toothbrush head 400 without using a storage box, which not only reduces the storage length, but also reduces the occupied space, making the electric toothbrush of this embodiment more convenient to carry.

[0046] In addition, it is understandable that the clamping member 200 only needs to be able to clamp the toothbrush head 400, so the length of the clamping member 200 does not need to be the same as the toothbrush handle 100, that is, the clamping member 200 is set as a small protruding structure on the side of the toothbrush handle 100, so the side of the toothbrush handle 100 still has enough space for the user to hold. It can be seen that the clamping member 200 provided in the electric toothbrush of this embodiment will not affect the size of the part of the toothbrush handle 100 for the user to hold, so as to ensure the user's hand feel when using it.

[0047] On the basis of the above embodiment, in order to make the toothbrush head 400 more firmly clamped to the toothbrush handle 100, the clamping member 200 includes two clamping parts 230 arranged opposite to each other to form a clamping groove 210, and at least one of the two clamping parts 230 is an elastic structure. For example, the connecting handle 410 of the toothbrush head 400 is set as a cylindrical structure, and the clamping groove 210 is set as a circular arc surface groove adapted thereto, and the diameter of the clamping groove 210 is smaller than (slightly smaller than) the diameter of the connecting handle 410, and the arc of the circular arc surface groove is greater than π / 2. Specifically, in the process of extending the toothbrush head 400 from the bayonet 220 into the slot 210, the connecting handle 410 will press against the clamping portion 230, and the clamping portion 230 of the elastic structure will be deformed to open the bayonet 220 to allow the connecting handle 410 to pass through and enter the slot 210. After the connecting handle 410 enters the slot 210, the clamping portion 230 of the elastic structure will restore and press against the connecting handle, so that the connecting handle is firmly clamped on the clamping member 200.

[0048] Alternatively, in some embodiments, the connecting handle 410 is configured as a frustum structure with a gradually decreasing diameter (eg Figure 2 As shown in the figure, the opening size of the bayonet 220 is larger than the minimum size of the connecting handle 410 and smaller than the maximum diameter of the connecting handle 410, so that the connecting handle 410 can extend from the bayonet 220 into the slot 210, and then by axially shifting the connecting handle 410, the large diameter portion of the connecting handle 410 is located in the slot 210, so that the connecting handle 410 is tightly snapped into the slot 210.

[0049] Reference Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of an electric toothbrush according to another embodiment of the utility model. Figure 4 for Figure 3 Schematic diagram of the electric toothbrush when it is stored. In some embodiments, the toothbrush handle 100 includes a first handle portion 110 and a second handle portion 120. The first handle portion 110 and the second handle portion 120 are rotatably connected around a rotating shaft perpendicular to the axis of the first handle portion 110 or the axis of the second handle portion 120. For example, the first handle portion 110 includes a first rotating portion 111, and the second handle portion 120 includes a second rotating portion 121. The first rotating portion 111 and the second rotating portion 121 are connected by a straight rotating shaft or an axial hole, so that the toothbrush handle 100 has a storage state in which the first handle portion 110 and the second handle portion 120 are folded relative to each other (such as Figure 4 ), and the expanded usage state (as shown Figure 3Specifically, when storing, the first handle 110 and the second handle 120 can be folded together to make the toothbrush handle 100 in a stored state. It can be understood that this embodiment utilizes the original detachability of the toothbrush head 400, and cooperates with the foldability of the toothbrush handle 100 to achieve three-stage folding storage of the electric toothbrush, which can greatly reduce the length of the electric toothbrush when stored, so that the electric toothbrush of this embodiment is more convenient to carry.

[0050] Based on the above embodiment, the length of the toothbrush head 400 is L1, the length of the first handle 110 is L2, the length of the second handle 120 is L3, 70mm≤L1≤80mm, 70mm≤L2≤80mm, 70mm≤L3≤80mm. Specifically, it can be understood that the overall length of an electric toothbrush for adults is about 200mm. This embodiment case sets the electric toothbrush into three parts of similar size according to the common size of existing electric toothbrushes, so that the electric toothbrush of this embodiment is smaller in length when stored and more convenient to carry.

[0051] Reference Figure 5 , Figure 5 for Figure 3 , in some embodiments, the electric toothbrush further includes a motor 600 and a power supply 700. The motor 600 is disposed in the first handle 110 and connected to the connecting member 300, and is used to drive the connecting member 300 to move, so as to drive the toothbrush head 400 to move. The power supply 700 is disposed in the second handle 120 and is electrically connected to the motor 600, and is used to supply power to the motor 600. Specifically, the motor 600 and the power supply 700 are respectively located in the first handle 110 and the second handle 120, and the space inside the first handle 110 and the second handle 120 is fully utilized, so that the space inside the toothbrush handle 100 is used more reasonably. In addition, it is understandable that in order to improve the battery life of the electric toothbrush, the power supply 700 is usually heavier than the motor 600. The power supply 700 is arranged on the second handle 120. On the one hand, it prevents the electric toothbrush from being top-heavy and makes the electric toothbrush more stable when standing upright. On the other hand, the center of gravity of the electric toothbrush is close to the second handle 120, or is located at the second handle 120, and the user usually holds the second handle 120 when using it, which makes it easier for the user to hold it.

[0052] Reference Figure 4 In some embodiments, the electric toothbrush further comprises a locking device 500, the locking device 500 comprises a locking member 510 (such as Figure 4As shown in the figure, one end of the locking member 510 is movably connected to one of the first handle 110 and the second handle 120, and the other end is detachably connected to the other of the first handle 110 and the second handle 120. Specifically, for example, the locking member 510 is movably connected to the second handle 120, and when in use, the other end of the locking member 510 is connected to the first handle 110 to achieve locking of the first handle 110 and the second handle 120, thereby preventing the first handle 110 from rotating relative to the second handle 120 when the user uses it, thereby improving the stability of the electric toothbrush of this embodiment. When stored, the locking member 510 is separated from the first handle 110 to release the lock on the first handle 110, so that the first handle 110 can rotate relative to the second handle 120 to achieve folding of the first handle 110 and the second handle 120.

[0053] For example, in some embodiments, the second handle 120 has a accommodating cavity 122 and a first mounting hole 123 connected to the accommodating cavity 122, and the first handle 110 has a connecting hole 112. When the toothbrush handle 100 is in use, the first mounting hole 123 and the connecting hole 112 are arranged toward each other, and one end of the locking member 510 can be movably connected to the accommodating cavity 122, and the other end extends from the first mounting hole 123 and extends into the connecting hole 112 to abut against the first handle 110 to keep the toothbrush handle 100 in use. It can be understood that arranging the locking member 510 on the inner wall of the electric toothbrush can, on the one hand, make the appearance of the electric toothbrush more beautiful, and on the other hand, make full use of the internal space of the electric toothbrush to make the structure of the electric toothbrush more compact, reduce the volume of the electric toothbrush, and thus reduce the space occupied by the electric toothbrush when stored. Specifically, for example, the size and profile of the connection hole 112 are matched with the size and profile of the locking member 510, so that when the locking member 510 is inserted into the connection hole 112, it abuts against the hole wall of the connection hole 112, thereby achieving the locking of the first handle 110 and the second handle 120. Specifically, the locking member 510 can move along the length direction of the second handle 120. When the electric toothbrush needs to be used, the locking member 510 is first moved to the inside of the second handle 120, and then the first handle 110 is rotated to a position coaxial with the second handle 120, and finally the locking member 510 is driven to move toward the first handle 110 and inserted into the connection hole 112, so as to achieve the locking of the first handle 110 and the second handle 120.

[0054] Or, refer to Figures 4 to 7 ,to Figure 7 , Figure 6 for Figure 5 A magnified schematic diagram of area A in the middle. Figure 7 for Figure 6 In some embodiments, the second handle 120 further has a first mounting hole 123 and a second mounting hole 124 (such as Figure 6The first mounting hole 123 is located at the end of the second handle 120, and the second mounting hole 124 is located at the side of the second handle 120. The first handle 110 also has a first locking portion 113 at the connecting hole 112. When the toothbrush handle 100 is in use, the locking surface is located on the side of the first locking portion 113 away from the second handle 120. The locking device 500 also includes an elastic member 530 and a switch 520 (as shown in FIG. Figure 6 and Figure 7 As shown in the figure, the locking member 510 has a main body 511 and a second locking portion 512 connected to the main body 511, the second locking portion 512 protrudes from the side of the main body 511, the main body 511 is movably connected to the accommodating cavity 122, and is penetrated through the first mounting hole 123, the second locking portion 512 is located outside the second handle 120, the switch 520 and the elastic member 530 are both connected to the main body 511, and the switch 520 is penetrated through the second mounting hole 124. The second locking portion 512 abuts against the locking surface under the elastic force of the elastic member 530, so that the toothbrush handle 100 remains in the use state; when the switch 520 is pressed toward the main body 511, that is, the switch 520 is pressed along the central axis of the second mounting hole 124, the second locking portion 512 can be moved and separated from the locking surface.

[0055] Specifically, by moving the locking member 510 along the length direction, it is necessary to open a second strip-shaped mounting hole 124 on the second handle 120 for the switch 520 to move. In this way, it is difficult to achieve a seal between the switch 520 and the hole wall of the second mounting hole 124, which will reduce the waterproof ability of the electric toothbrush handle 100. In order to ensure the waterproof performance of the electric toothbrush, the electrical components inside the toothbrush handle 100 need to have higher waterproof requirements, which will increase the cost of the electric toothbrush. This embodiment can effectively improve this problem. In this embodiment, the switch 520 is pressed along the central axis of the second mounting hole 124, which makes it easier to achieve a seal between the switch 520 and the hole wall of the second mounting hole 124, for example, a sealant or a sealing ring is set between the switch 520 and the hole wall of the second mounting hole 124.

[0056] Specifically, the dimensions of the connecting hole 112 and the second mounting hole 124 along the centerline axis of the second mounting hole 124 are larger than the dimensions of the locking member 510, so that the locking member 510 can move in the first mounting hole 123 and the connecting hole 112 to achieve the abutment and separation between the first locking portion 113 and the second locking portion 512. For example, the switch 520 and the elastic member 530 are disposed on two surfaces of the locking member 510 opposite to each other. When the switch 520 is pressed, the locking member 510 moves away from the second mounting hole 124, and the elastic member 530 is compressed. When the user releases the switch 520, the switch 520 can move toward the second mounting hole 124 under the elastic force of the elastic member 530. Alternatively, the locking member 510 also includes a third rotating portion 513 (such as Figure 7 As shown), the third rotating portion 513 is connected to the main body 511, and the main body 511 is rotatably connected to the second handle 120 through the third rotating portion 513. The elastic member 530 and the switch 520 are both connected to the surface of the main body 511 away from the second locking portion 512, and the switch 520 is located on the side of the third rotating portion 513 away from the second locking portion 512, and the elastic member 530 is located on the side of the third rotating portion 513 close to the second locking portion 512. When the switch 520 is pressed, the end of the main body 511 away from the second locking portion 512 rotates away from the second mounting hole 124, and correspondingly, the locking portion rotates toward the second mounting hole 124, and the main body 511 presses the elastic member 530 to release the switch 520, and the main body 511 can rotate under the elastic force of the elastic member 530. Thus, under the action of the switch 520 and the elastic member 530 , the second locking portion 512 of the locking member 510 can move, so as to achieve the abutment and separation between the second locking portion 512 and the locking surface.

[0057] In addition, the first handle 110 can be formed by assembling a first housing 114 and a first end cover 115. The first housing 114 has a first installation cavity 1141 and a first opening communicating with the first installation cavity 1141. The motor 600 can extend from the first opening into the first installation cavity 1141 and be fixed in the first installation cavity 1141. The first end cover 115 is connected to the first housing 114 and covers the first opening. The first end cover 115 has a first through hole forming a connecting hole 112, or the outer periphery of the first end cover 115 has a first notch 1151. The first notch 1151 and the hole wall of the first opening define the connecting hole 112. The first end cover 115 at the first notch 1151 forms a first locking portion 113. The surface of the first end cover 115 facing the first installation cavity 1141 includes a locking surface. Similarly, the second handle 120 is formed by assembling a second housing 125 and a second end cover 126. The second housing 125 has a second mounting cavity 1251 and a second opening communicating with the second mounting cavity 1251. The second mounting cavity 1251 includes a receiving cavity 122. The power supply 700 can extend from the second opening into the second mounting cavity 1251 and be fixed in the second mounting cavity 1251. The second end cover 126 is connected to the second housing 125 and covers the second opening. The second end cover 126 has a second through hole 1261, which forms the first mounting hole 123. Alternatively, the outer periphery of the second end cover 126 has a second notch, and the second notch and the hole wall of the second opening define the second mounting hole 124.

[0058] It should be noted that the attached Figure 4 The dotted line in FIG. 1 is not to be interpreted as a contour line on the first handle portion 110 , but is only used to clearly show the first locking portion 113 .

[0059] In some embodiments, the electric toothbrush includes a rotating mechanism, which includes a first rotating member, a second rotating member, and a damping member, wherein the damping member is disposed between the first rotating member and the second rotating member, wherein one of the first rotating member and the second rotating member is connected to the first handle 110, and the other is connected to the second handle 120. On the one hand, the user has a damping feeling during the process of driving the first handle 110 and the second handle 120 to rotate relative to each other, thereby improving the user's experience during use. On the other hand, the damping member can limit the rotation of the first handle 110 and the second handle 120 to a certain extent, so that the first handle 110 and the second handle 120 are kept in a mutually folded storage state as much as possible during storage, thereby preventing the first handle 110 and the second handle 120 from being damaged by collision due to free rotation.

[0060] Reference Figures 1 to 4In some embodiments, the toothbrush head 400 includes bristles 420, and the toothbrush handle 100 further includes a protective groove 130, which is located at the side of the toothbrush handle 100.
