[0047] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0048] Reference below Figure 1-Figure 11 An electric toothbrush 100 according to an embodiment of the present invention is described.

[0049] like Figure 1 and Figure 2As shown, the electric toothbrush 100 according to the embodiment of the utility model includes: a handle shell 10, a mounting bracket 20 and a plurality of batteries 30, the mounting bracket 20 is arranged in the handle shell 10, the mounting bracket 20 forms a first mounting space 21, the plurality of batteries 30 are electrically connected, and the plurality of batteries 30 are arranged in the first mounting space 21, wherein the mounting bracket 20 and the plurality of batteries 30 are respectively limited in position on one axial and radial side of the battery 30, and the handle shell 10 and the plurality of batteries 30 are limited in position on the other radial side of the battery 30.

[0050] Specifically, a single battery or two batteries are generally installed in the mounting bracket of a traditional electric toothbrush. An electric toothbrush with a single battery has insufficient power and cannot meet the needs of long-term use, and needs to be charged multiple times. An electric toothbrush with two batteries has problems of shaking and instability, and the two batteries or the batteries and the mounting bracket and the handle shell may collide and wear due to looseness, causing damage to the electric toothbrush, and the circuit inside the electric toothbrush is prone to short circuit.

[0051] Therefore, the electric toothbrush 100 needs to be optimized in design. The mounting bracket 20 in the electric toothbrush 100 is located in the handle shell 10, and the handle shell 10 can protect the mounting bracket 20. A first mounting space 21 is provided in the middle of the mounting bracket 20, and a receiving groove is formed in the first mounting space 21, so that it is convenient to place multiple batteries 30. The multiple batteries 30 can be connected in series, which can improve the long-term endurance of the electric toothbrush 100, or the multiple batteries 30 can be connected in parallel, and multiple power supply circuits can be formed in the electric toothbrush 100. When one of the multiple batteries 30 fails to work or is damaged, the electric toothbrush 100 can still work, thereby improving the service life and reliability of the electric toothbrush 100.

[0052] Furthermore, the mounting bracket 20 and the multiple batteries 30 are respectively limited in the axial and radial sides of the battery 30. Specifically, the mounting bracket 20 and the multiple batteries 30 are limited in the axial direction of the battery 30, which can limit the movement of the multiple batteries 30 in the axial direction of the battery 30, thereby ensuring that the multiple batteries 30 and the mounting bracket 20 are more firmly fixed in the axial direction of the battery 30, and can also prevent the multiple batteries 30 from being misaligned in the axial direction of the battery 30, thereby ensuring the stability of the circuit between the multiple batteries 30 and avoiding short circuits.

[0053] Moreover, the mounting bracket 20 cooperates with the multiple batteries 30 in the radial limit of the battery 30, which can limit the movement of the multiple batteries 30 in the radial direction of the battery 30, thereby ensuring that the multiple batteries 30 and the mounting bracket 20 are more firmly fixed in the radial direction of the battery 30, and can also prevent the multiple batteries 30 from being misaligned in the radial direction of the battery 30, thereby further improving the stability of the connection between the multiple batteries 30 and the mounting bracket 20 and the stability of the circuit, avoiding short circuits, and also improving the service life of the electric toothbrush 100.

[0054] In addition, the handle shell 10 and the multiple batteries 30 are limited in position on the other radial side of the battery 30. In this way, the multiple batteries 30 are not only limited in position with the mounting bracket 20 on one axial and radial side of the battery 30, but also limited in position with the handle shell 10 on the other radial side of the battery 30, thereby further improving the strength of the connection between the multiple batteries 30 and the mounting bracket 20 and the handle shell 10 respectively, and also preventing the multiple batteries 30 from axially or radially moving relative to the mounting bracket 20 and the handle shell 10.

[0055] Therefore, the electric toothbrush 100 can not only ensure long-term battery life, but also limit the axial and radial movement of multiple batteries 30 relative to the mounting bracket 20, so that the multiple batteries 30 and the mounting bracket 20 can be fixed more firmly in the axial and radial directions of the batteries 30, and can also prevent the axial and radial misalignment between the multiple batteries 30, thereby ensuring the stability of the circuit connection between the multiple batteries 30 and avoiding circuit failures between the multiple batteries 30.

[0056] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, the mounting bracket 20 includes: a bracket body 22, a first limit plate 23 and a second limit plate 24, the first limit plate 23 and the second limit plate 24 are respectively arranged on the bracket body 22, the first limit plate 23 and the second limit plate 24 are arranged at intervals along the axial direction of the battery 30, the bracket body 22, the first limit plate 23 and the second limit plate 24 jointly form a first mounting space 21, the first limit plate 23 and the second limit plate 24 are respectively matched with the multiple batteries 30 in the axial upper limit position of the battery 30, and the bracket body 22 is matched with the multiple batteries 30 in the radial side limit position of the battery 30.

[0057] The mounting bracket 20 is mainly composed of a bracket body 22, a first limiting plate 23 and a second limiting plate 24, which are arranged at intervals in the axial direction of the battery 30. The bracket body 22, the first limiting plate 23 and the second limiting plate 24 jointly form a receiving groove, so that it is convenient to place multiple batteries 30. Multiple batteries 30 are between the first limiting plate 23 and the second limiting plate 24, so that the multiple batteries 30 can be limited to move along the axial direction of the battery 30, and the axial direction is the front-back direction of the electric toothbrush 100.

[0058] Moreover, the bracket body 22 and the multiple batteries 30 are limited on the radial side of the battery 30, so as to limit the movement of the multiple batteries 30 on the radial side of the battery 30, thereby avoiding the battery 30 from colliding with the inner wall of the mounting bracket 20, thereby avoiding damage to the surface of the battery 30 and preventing the mounting bracket 20 from being deformed due to long-term collision.

[0059] In addition, since the battery 30 is generally configured as a cylindrical battery 30, in order to increase the contact area between the battery 30 and the first limiting plate 23 and the second limiting plate 24, the first limiting plate 23 and the second limiting plate 24 are correspondingly configured as circular plates. In this way, the contact area between the battery 30 and the first limiting plate 23 and the second limiting plate 24 can be increased, and the force between each other can also be reduced, thereby improving the stability of the connection between the battery 30 and the first limiting plate 23 and the second limiting plate 24.

[0060] According to the specific embodiment of the utility model, Figure 3 and Figure 4 As shown, multiple batteries 30 are arranged sequentially along the axial direction of the battery 30, the battery 30 located at one end of the multiple batteries 30 cooperates with the first limit plate 23 at the axial upper limit position of the battery 30, and the battery 30 located at the other end of the multiple batteries 30 cooperates with the second limit plate 24 at the axial upper limit position of the battery 30.

[0061] Specifically, multiple batteries 30 are connected in series in the first installation space 21, and one end of the battery 30 in contact with the first limiting plate 23 is limited by the first limiting plate 23, which can prevent the multiple batteries 30 from moving forward and avoid the multiple batteries 30 from colliding with the front part of the electric toothbrush 100, thereby protecting the front part of the electric toothbrush 100.

[0062] In addition, the batteries 30 in contact with the second limiting plate 24 among the multiple batteries 30 are limited by the second limiting plate 24, which can prevent the multiple batteries 30 from moving backwards and also prevent the multiple batteries 30 from colliding with the rear part of the electric toothbrush 100, thereby protecting the rear part of the electric toothbrush 100.

[0063] According to another embodiment of the present invention, a plurality of batteries 30 are arranged side by side along the radial direction of the batteries 30 , and each battery 30 is respectively limited and matched with the first limiting plate 23 and the second limiting plate 24 .

[0064] Specifically, multiple batteries 30 are arranged side by side along the radial direction of the battery 30. For example, multiple batteries 30 can be arranged in two rows and two columns. In this way, not only the number of batteries 30 can be increased, but also the overall length of the electric toothbrush 100 can be reduced. By reducing the volume of the electric toothbrush 100, the overall weight can also be reduced, thereby improving the battery life of the electric toothbrush 100 and facilitating storage.

[0065] According to some embodiments of the present invention, Figure 4 As shown, at least one end of the bracket body 22 in the width direction is provided with an elastic arm 40, the elastic arm 40 is arc-shaped, and the elastic arm 40 abuts against the outer peripheral wall of the battery 30, so that the battery 30 can be kept fixed in its radial direction.

[0066] Among them, elastic arms 40 are arranged on both sides of the width direction of the bracket body 22, and there are multiple elastic arms 40, and the multiple elastic arms 40 are arranged at intervals along the length direction of the bracket body 22. In this way, the multiple elastic arms 40 abut and cooperate with the outer peripheral wall of the battery 30. The elastic arms 40 can make the elastic arms 40 and the outer peripheral wall of the battery 30 fit more tightly and firmly through elastic deformation, thereby preventing the multiple batteries 30 from moving relative to the mounting bracket 20 in the axial direction and radial direction of the battery 30.

[0067] Furthermore, multiple elastic arms 40 are connected and matched with multiple batteries 30 in a one-to-one correspondence. Specifically, one battery 30 can be limited by two relatively arranged elastic arms 40, thereby preventing multiple batteries 30 from moving in the axial direction and radial direction of the battery 30.

[0068] In addition, the elastic arm 40 is an arc-shaped elastic arm 40, so that the elastic arm 40 can be fully fitted with the outer surfaces of multiple batteries 30, thereby increasing the contact area between the elastic arm 40 and the outer surface of the battery 30, and also playing a role in protecting the outer surface of the battery 30.

[0069] According to some embodiments of the present invention, Figure 3 As shown, the electric toothbrush 100 further includes a buffer 50, which is disposed between at least one battery 30 and the handle shell 10, so that one battery 30 is kept fixed along its radial direction.

[0070] Among them, the buffer part 50 is located between the battery 30 and the inner wall surface of the handle shell 10, so that the connection between the battery 30 and the handle shell 10 can be tighter. In this way, when the motor vibrates, it can prevent the battery 30 from slipping relative to the handle shell 10, and can also prevent the battery 30 from contacting the inner wall surface of the handle shell 10, thereby protecting the battery 30.

[0071] According to some embodiments of the present invention, the buffer 50 is an integral part, the buffer 50 is located on one radial side of at least two batteries 30 , and the buffer 50 is connected to the at least two batteries 30 respectively.

[0072] The buffer member 50 is an integrated member, which can improve the stability and reliability of the electric toothbrush 100 , reduce friction and wear between components, and reduce the failure rate, thereby extending the service life of the electric toothbrush 100 .

[0073] Furthermore, the buffer 50 is located on one radial side of at least two batteries 30. When the two batteries 30 are axially docked, the buffer 50 is disposed at the connection between the two batteries 30. The buffer 50 is bonded to the connection between the two batteries 30, thereby further improving the stability of the connection between the batteries 30.

[0074] According to some embodiments of the present invention, Figure 3 As shown, the plurality of batteries 30 are arranged in sequence along the axial direction of the batteries 30 , and the buffer 50 extends between at least two batteries 30 along the axial direction of the batteries 30 .

[0075] The plurality of batteries 30 are sequentially arranged along the axial direction of the battery 30, so that the plurality of batteries 30 can be connected in series along the axial direction of the battery 30, and the buffer 50 extends between at least two batteries 30 along the axial direction of the battery 30, so that the buffer 50 can be connected to the two batteries 30 at the same time. Moreover, the buffer 50 passes through the corresponding ends of two adjacent batteries 30, so that the ends of the two batteries 30 can be prevented from being subjected to impact force during installation, and has a buffering effect, so that the ends of the batteries 30 can be protected during installation.

[0076] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, the electric toothbrush 100 further includes: a first conductive member 60, which is respectively connected to two adjacent batteries 30, so that the two adjacent batteries 30 can be electrically connected.

[0077] The first conductive member 60 is located between the two batteries 30 , one end of the first conductive member 60 is connected to one battery 30 , and the other end of the first conductive member 60 is connected to the other battery 30 , thereby ensuring the stability of the circuit connection between the two adjacent batteries 30 .

[0079] Specifically, the first conductive segment is welded to one end of two adjacent batteries 30, and the second conductive segment is welded to the other end of the two adjacent batteries 30, or the first conductive segment and the second conductive segment both extend radially out of the battery 30 and then are welded, so that the series connection of the two adjacent batteries 30 can be achieved.

[0080] Furthermore, the second conductive segment is bent relative to the first conductive segment, so that the second conductive segment and the first conductive segment are arranged opposite to each other along the axial direction of the battery 30, the first conductive segment is connected to one end of two adjacent batteries 30, and the second conductive segment is connected to the other end of the two adjacent batteries 30, thereby ensuring the stability of the circuit connection between the two adjacent batteries 30.

[0081] According to another embodiment of the present invention, a portion of the first conductive segment and a portion of the second conductive segment protrude from the battery 30 in a radial direction of the battery 30 , and a portion of the first conductive segment and a portion of the second conductive segment are welded and connected.

[0082] Among them, by protruding a part of the conductive segment in the radial direction of the battery 30 and performing welding connection, it can ensure that the electrical connection between the battery 30 and the conductive segment is firm and reliable, and can also reduce electrical problems caused by poor connection. In addition, the welding connection can enhance the mechanical connection strength between the conductive segment and the battery 30, which can prevent loosening or breaking during use, thereby improving reliability and durability.

[0083] According to some embodiments of the present invention, Figure 7 As shown, the electric toothbrush 100 also includes: a first adhesive member 70, which is bonded between the first conductive segment and the second conductive segment. The first adhesive member 70 can be an adhesive tape. The first conductive segment and the second conductive segment are bonded separately by the first adhesive member 70, so that the bonding between two adjacent batteries 30 can be more firmly.

[0084] According to some embodiments of the present invention, Figure 8As shown, the electric toothbrush 100 further includes: a second adhesive member 71 , which is adhered to the outer peripheral wall of two adjacent batteries 30 , and the second adhesive member 71 is located outside the first conductive member 60 in the radial direction of the battery 30 .

[0085] When two adjacent batteries 30 are arranged side by side in the radial direction, the second adhesive member 71 may also be an adhesive tape, and the second adhesive member 71 is respectively bonded to the outer peripheral walls of the two adjacent batteries 30 , so that the outer peripheral walls of the two adjacent batteries 30 can be connected more stably and firmly.

[0086] Furthermore, there are multiple second adhesive members 71 , and the multiple second adhesive members 71 are arranged at intervals along the circumference of the battery 30 , thereby further improving the stability of the connection between the outer peripheral walls of two adjacent batteries 30 .

[0087] According to another embodiment of the utility model, a plurality of batteries 30 are arranged side by side along the radial direction of the battery 30, a first conductive member 60 extends along the radial direction of the battery 30, and two ends of the first conductive member 60 are respectively connected to two adjacent batteries 30, so that two adjacent batteries 30 can be connected in series.

[0088] According to some embodiments of the present invention, Fig.11 As shown, the electric toothbrush 100 further includes: a third adhesive member 72 , and the third adhesive member 72 is bonded to the outer peripheral wall of two adjacent batteries 30 .

[0089] The third adhesive member 72 may be configured as an adhesive tape, and the third adhesive member 72 is bonded to the outer peripheral wall between two adjacent batteries 30 along the axial direction of the battery 30 , thereby ensuring the stability of the connection between the two adjacent batteries 30 in the axial direction.

[0090] According to a specific embodiment of the present invention, the third adhesive member 72 is generally arc-shaped, so that the contact area between the third adhesive member 72 and the outer peripheral wall of two adjacent batteries 30 can be increased, so that the connection between the two adjacent batteries 30 can be more stable and firm.

[0091] According to some embodiments of the present invention, Fig. 9 As shown, the electric toothbrush 100 further includes: a circuit board 80 , and the battery 30 is disposed on a side of the mounting bracket 20 away from the multiple batteries 30 , and the circuit board 80 is electrically connected to the multiple batteries 30 .
