Description

Technical Field

[0001] The utility model relates to the technical field of toiletries, and particularly relates to a display structure of an electric toothbrush and an electric toothbrush. Background Art

[0002] With the development of society, people pay more and more attention to dental health. Electric toothbrushes with better cleaning effects have gradually been popularized in people's lives, and their functions are also more diversified. Electric toothbrushes on the market have functions such as Bluetooth connection, pressure sensing, strength adjustment, wireless charging, etc. Most of the above functions require a display device to prompt users. Therefore, the quality of the display effect of an electric toothbrush can better reflect the texture and design of the product. In the existing solutions, the lamp beads of an electric toothbrush are generally arranged on a circuit board. Since the handle shell is a cylindrical structure, setting multiple lamp beads on the circuit board will cause an increase in the handle size, and the positions of the multiple lamp beads are suspended from the shell, resulting in unreasonable space utilization. Moreover, the light of the lamp beads is scattered and irradiated on the handle shell, and the display effect is poor, affecting the overall texture. Summary of the Utility Model

[0003] The main purpose of the utility model is to propose a display structure of an electric toothbrush and an electric toothbrush, aiming to improve the problem of poor display effect of the electric toothbrush.

[0004] To achieve the above purpose, the display structure of the electric toothbrush proposed by the utility model includes:

[0005] A handle shell, with an installation cavity inside, and at least part of the handle shell is set as a light-transmitting area;

[0006] A bracket, arranged in the installation cavity;

[0007] A circuit board, which is limited and installed on the bracket and is arranged between the bracket and the inner wall surface of the handle shell;

[0008] Lamp beads, arranged on one side of the circuit board close to the inner wall surface of the shell and corresponding to the light-transmitting area;

[0009] A light-shielding member, with a light-passing hole penetrating through it. The light-shielding member is installed on the side of the circuit board away from the bracket. The light-passing hole corresponds to the lamp beads, and the light emitted by the lamp beads passes through the light-passing hole and irradiates the light-transmitting area of the shell.

[0010] In an embodiment, the light-shielding member has a first abutting surface and a second abutting surface. The first abutting surface is attached to the surface of the circuit board. The handle shell is cylindrical. The second abutting surface is a curved surface and is attached to the inner wall surface of the handle shell. The light-passing hole penetrates through the first abutting surface and the second abutting surface.

[0011] In one embodiment, a connecting portion is provided on the first abutting surface of the light-shielding member, and a first mounting hole is provided on the circuit board. The connecting portion is embedded in the first mounting hole so that the light-shielding member is detachably connected to the circuit board, and the lamp beads are arranged in the light-passing holes.

[0012] In one embodiment, the number of the connecting portions is multiple. The multiple connecting portions are arranged along the circumferential direction of the light-shielding member and are spaced from the light-passing holes. The number of the first mounting holes is the same as that of the connecting portions.

[0013] In one embodiment, the number of the lamp beads is multiple. The multiple lamp beads are arranged along the width direction of the circuit board. The number of the light-passing holes is the same as that of the lamp beads and is spaced along the length direction of the light-shielding member. The light passing through each of the light-passing holes is isolated from each other.

[0014] In one embodiment, the electric toothbrush display structure further includes a lamp cap. A second mounting hole is provided in the light-transmitting area of the housing corresponding to the lamp beads. The lamp cap is arranged in the second mounting hole, and the light emitted by the lamp beads passes through the lamp cap and reaches outside the handle housing.

[0015] In one embodiment, the bracket includes an upper bracket and a lower bracket. The upper bracket is detachably connected to the lower bracket. One end of the circuit board is connected to the upper bracket, and the other end of the circuit board is connected to the lower bracket. The upper bracket is used for mounting the motor assembly, and a battery is arranged in the lower bracket. The lamp beads are mounted at one end of the circuit board close to the lower bracket and are electrically connected to the battery.

[0016] In one embodiment, the electric toothbrush display structure further includes a button and a microswitch. The microswitch is arranged at one end of the circuit board close to the upper bracket. The handle housing is provided with a pressing portion corresponding to the microswitch. The button is connected to the side of the pressing portion far from the microswitch, and the microswitch is electrically connected to the lamp beads.

[0017] In one embodiment, a limiting portion is provided on the upper bracket, and a buckle and a limiting post are respectively provided on the lower bracket. A limiting hole is provided on the circuit board. The limiting post is embedded in the limiting hole. The limiting portion connects one end of the circuit board close to the upper bracket, and the buckle clamps one end of the circuit board close to the lower bracket.

[0018] The present invention also provides an electric toothbrush, including the electric toothbrush display structure in any of the foregoing embodiments.

[0019] The technical solution of the present utility model improves the display effect of the electric toothbrush by adding a light-shielding member between the lamp beads on the circuit board and the inner wall surface of the housing. Specifically, the display structure of the electric toothbrush includes a handle housing, a bracket, a circuit board, lamp beads, and a light-shielding member. An installation cavity is provided inside the handle housing, and at least part of the handle housing is set as a light-transmitting area, that is, the handle housing is made of a light-transmitting material, and the light in the installation cavity can pass through the light-transmitting area to reach the outside of the handle housing. The bracket is arranged in the installation cavity and connected to the housing. The circuit board is limited and installed on the bracket and is located between the bracket and the inner wall surface of the handle housing. The lamp beads are miniature LED patch lights arranged on the circuit board, and the lamp beads are arranged corresponding to the light-transmitting area. The light-shielding member is installed on the circuit board and covers the lamp beads. The light-shielding member is provided with a light-passing hole, so that the light emitted by the lamp beads reaches the outside of the handle housing in sequence from the light-passing hole and the light-transmitting area, providing information to the user.

[0020] It should be noted that as the functions of the electric toothbrush gradually increase, information such as battery power, Bluetooth connection, and vibration intensity needs to be displayed on the handle housing. One or more lamp beads are arranged on the circuit board to irradiate the light-transmitting area of the handle housing. Corresponding information patterns are usually provided on the outer surface of the handle housing. However, there is a certain distance between the lamp beads on the circuit board and the inner wall surface of the housing. Therefore, the light cannot be concentrated when the lamp beads irradiate the handle housing, resulting in a poor display effect and reducing the overall texture of the electric toothbrush. In this solution, a light-shielding member is used to fill the space between the lamp beads and the handle housing. The light emitted by the lamp beads passes through the light-passing hole of the light-shielding member to reach the handle housing, which can improve the irradiation brightness while avoiding light leakage, enhance the display effect, and improve the overall texture of the product. At the same time, the light-shielding member also plays a supporting role. During the use of the electric toothbrush, the motor assembly in the bracket drives the circuit board to vibrate, and the light-shielding member can transfer the vibration from the circuit board to the handle housing, making the structure of the electric toothbrush compact and avoiding loosening and collision of internal parts.

[0036] The present utility model provides an electric toothbrush display structure.

[0037] Please refer to Figures 1 to 7 , in an embodiment of the present utility model, the electric toothbrush display structure 100 includes a handle housing 110, a bracket 120, a circuit board 130, a lamp bead 131, and a light-shielding member 140. An installation cavity 110a is provided inside the handle housing 110. At least a part of the handle housing 110 is set as a light-transmitting area 111, that is, the handle housing 110 is made of a light-transmitting material. The light in the installation cavity 110a can pass through the light-transmitting area 111 to reach the outside of the handle housing 110. The bracket 120 is arranged in the installation cavity 110a and connected to the housing. The circuit board 130 is limited and installed on the bracket 120 and is located between the bracket 120 and the inner wall surface of the handle housing 110. The lamp bead 131 is a micro LED patch lamp arranged on the circuit board 130, and the lamp bead 131 is arranged corresponding to the light-transmitting area 111. The light-shielding member 140 is installed on the circuit board 130 and covers above the lamp bead 131. The light-shielding member 140 is provided with a light-passing hole 140a in a penetrating manner, so that the light emitted by the lamp bead 131 reaches the outside of the handle housing 110 in sequence from the light-passing hole 140a and the light-transmitting area 111 to provide information to the user.

[0038] It should be noted that as the functions of existing electric toothbrushes gradually increase, information such as battery level, Bluetooth connection, and vibration intensity needs to be displayed on the handle housing 110. One or more light beads 131 are provided on the circuit board 130 to irradiate the light-transmissive area 111 of the handle housing 110. Corresponding information patterns are usually provided on the outer surface of the handle housing 110. However, there is a certain distance between the light beads 131 on the circuit board 130 and the inner wall surface of the housing. Therefore, the light from the light beads 131 cannot be concentrated when irradiating the handle housing 110, resulting in a poor display effect and reducing the overall texture of the electric toothbrush 1.

[0039] In this solution, a light-shielding member 140 is filled between the light beads 131 and the handle housing 110. The light emitted by the light beads 131 passes through the light-transmitting holes 140a of the light-shielding member 140 to reach the handle housing 110, which can improve the irradiation brightness while avoiding light leakage, enhance the display effect, and improve the overall texture of the product. Further, the light-shielding member 140 also plays a supporting role. During the use of the electric toothbrush 1, the motor assembly 11 in the bracket 120 drives the circuit board 130 to vibrate, and the light-shielding member 140 can transfer the vibration from the circuit board 130 to the handle housing 110, so that the internal structure of the electric toothbrush is compact and the movement parts are prevented from loosening and colliding.

[0040] In one embodiment, the light-shielding member 140 has a first abutting surface 141 and a second abutting surface 142. The first abutting surface 141 is attached to the surface of the circuit board 130. The handle housing 110 is cylindrical, and the second abutting surface 142 is a curved surface and is attached to the inner wall surface of the handle housing 110. The light-transmitting holes 140a penetrate through the first abutting surface 141 and the second abutting surface 142.

[0041] As Figure 5 shown, in an embodiment of the present utility model, the handle housing 110 is cylindrical. The light-shielding member 140 is disposed between the circuit board 130 and the inner wall surface of the handle housing 110. A flat first abutting surface 141 is provided on the side of the light-shielding member 140 facing the circuit board 130, and a curved second abutting surface 142 is provided on the side of the light-shielding member 140 facing the inner wall surface of the handle housing 110. The first abutting surface 141 is attached to the surface of the circuit board 130, and the second abutting surface 142 is attached to the inner wall surface of the handle housing 110. The light-transmitting holes 140a penetrate through the first abutting surface 141 and the second abutting surface 142. The light emitted by the light beads 131 can be concentrated from the light-transmitting holes 140a to the inner wall surface of the handle housing 110 corresponding to the light-transmitting holes 140a to illuminate the pattern on the handle housing 110 to give a prompt to the user. By attaching the first abutting surface 141 and the second abutting surface 142 to the circuit board 130 and the handle housing 110 respectively, light leakage can be avoided during the propagation of light, and the circuit board 130 can be abutted against the handle housing 110 through the light-shielding member 140, so that the connection between the components is tight and the stability of the structure is improved.

[0042] In one embodiment, a connecting portion 143 is provided on the first abutting surface 141 of the light-shielding member 140, and a first mounting hole 130a is provided on the circuit board 130. The connecting portion 143 is embedded in the first mounting hole 130a so that the light-shielding member 140 is detachably connected to the circuit board 130, and the lamp bead 131 is disposed in the light-passing hole 140a.

[0043] As Figure 5 shown, in one embodiment of the present invention, the connecting portion 143 protrudes in the direction towards the circuit board 130 on the first abutting surface 141. The connecting portion 143 is cylindrical. A first mounting hole 130a corresponding to the connecting portion 143 is formed on the circuit board 130. By embedding the connecting portion 143 into the first mounting hole 130a, the light-shielding member 140 is fixedly mounted on the circuit board 130. The width of the light-passing hole 140a is greater than the width of the lamp bead 131. When the light-shielding member 140 is mounted on the circuit board 130, the first abutting surface 141 is in contact with the surface of the circuit board 130, and the lamp bead 131 protruding on the circuit board 130 extends into the light-passing hole 140a. When disassembly is required, the connecting portion 143 is pulled out of the first mounting hole 130a to separate the light-shielding member 140 from the circuit board 130. As can be seen from the above, the detachable connection between the light-shielding member 140 and the circuit board 130 can be achieved through the above operations, improving the convenience of installing the light-shielding member 140.

[0044] In one embodiment, the number of the connecting portions 143 is multiple. The multiple connecting portions 143 are arranged along the circumferential direction of the light-shielding member 140 and are spaced apart from the light-passing hole 140a. The number of the first mounting holes 130a is the same as the number of the connecting portions 143.

[0045] As Figure 5 shown, in order to improve the connection stability between the light-shielding member 140 and the circuit board 130, in one embodiment of the present invention, the number of the connecting portions 143 on the first abutting surface 141 is set to be multiple. The multiple connecting portions 143 are arranged around the circumferential direction of the light-shielding member 140 and are spaced apart from the light-passing hole 140a. A plurality of first mounting holes 130a are correspondingly provided on the circuit board 130. The lamp beads 131 are fixed on the circuit board 130 avoiding the plurality of first mounting holes 130a. The connecting portions 143 and the first mounting holes 130a are in one-to-one correspondence, so that the first abutting surface 141 can be in contact with the surface of the circuit board 130, avoiding light leakage of the lamp beads 131, and at the same time improving the connection strength between the light-shielding member 140 and the circuit board 130, preventing the light-shielding member 140 from becoming loose during the assembly process.

[0046] In one embodiment, the number of lamp beads 131 is multiple, and the multiple lamp beads 131 are arranged along the width direction of the circuit board 130. The number of light passing holes 140a is the same as that of the lamp beads 131 and is arranged at intervals along the length direction of the light shielding member 140. The light rays passing through each light passing hole 140a are isolated from each other.

[0047] As Figure 2 and Figure 5 shown, in an embodiment of the present utility model, the number of lamp beads 131 is set to three and is arranged at intervals along the width direction of the circuit board 130. The number of light passing holes 140a on the light shielding member 140 is also set to three and is arranged at intervals along its own length direction. The light of each lamp bead 131 irradiates the inner side wall of the handle housing 110 through the light passing hole 140a at its respective position. The light passes through the handle housing 110 and reaches the outside to give a prompt message to the user. Since the light shielding member 140 is made of a light-impermeable material, the light rays in each light passing hole 140a are isolated from each other, and there will be no interference situation. The display effect of each lamp bead 131 is clear and easy to distinguish, which can improve the texture of the electric toothbrush 1.

[0048] In one embodiment, the electric toothbrush display structure 100 further includes a lamp cap 150. A second mounting hole 111a is provided in the light transmissive area 111 of the housing corresponding to the lamp bead 131. The lamp cap 150 is disposed in the second mounting hole 111a, and the light emitted by the lamp bead 131 passes through the lamp cap 150 and reaches outside the handle housing 110.

[0049] As Figure 3 and Figure 7 shown, in another embodiment of the present utility model, the electric toothbrush display structure 100 further includes a lamp cap 150. Specifically, the handle housing 110 itself is made of an opaque material. The light transmissive area 111 of the handle housing 110 opposite to the lamp bead 131 is provided with a through mounting hole, and a lamp cap 150 is arranged in the mounting hole to transmit the light emitted by the lamp bead 131 to outside the handle housing 110. In this embodiment, the number of lamp beads 131 is one, and the number of lamp caps 150 is set to one. In some other embodiments of the present utility model, the number of lamp beads 131 is multiple and the number of lamp caps 150 is the same as that of the lamp beads 131. The light of each lamp bead 131 passes through the corresponding light passing hole 140a on the light shielding member 140 and irradiates the lamp cap 150. The lamp cap 150 can be made of a material with good light transmissive performance to make the display effect better and further reduce the divergence of light.

[0050] In one embodiment, the bracket 120 includes an upper bracket 121 and a lower bracket 122. The upper bracket 121 and the lower bracket 122 are detachably connected. One end of the circuit board 130 is connected to the upper bracket 121, and the other end of the circuit board 130 is connected to the lower bracket 122. The upper bracket 121 is used to mount the motor assembly 11. A battery 160 is provided in the lower bracket 122. The lamp beads 131 are installed at one end of the circuit board 130 close to the lower bracket 122 and are electrically connected to the battery 160.

[0051] As Figure 2 shown, in one embodiment of the present utility model, the bracket 120 includes an upper bracket 121 and a lower bracket 122. Further referring to Figure 6 , a chute 121a is provided on the upper bracket 121, and a slider 1221 is provided on the lower bracket 122 corresponding to the chute 121a. By sliding the slider 1221 into / out of the chute 121a, the upper bracket 121 and the lower bracket 122 are detachably connected. The circuit board 130 extends along the length direction of the bracket 120. One end of the circuit board 130 is snap-connected to the upper bracket 121, and the end of the circuit board 130 away from the upper bracket 121 is connected to the lower bracket 122. The upper bracket 121 is used to mount the motor assembly 11. A battery 160 is provided in the lower bracket 122. The battery 160 is electrically connected to the lamp beads 131 on the circuit board 130 to supply electrical energy to the lamp beads 131. It can be understood that the bracket 120 is set as the upper bracket 121 and the lower bracket 122, which are respectively used to mount the motor assembly 11 and the battery 160, so that the movement of the electric toothbrush 1 is designed in a modular manner, facilitating the assembly of components. By adding a gasket 180 between the upper bracket 121 and the lower bracket 122, a buffering and shock-absorbing effect can be achieved.

[0052] In one embodiment, the electric toothbrush display structure 100 further includes a button 170 and a micro switch 132. The micro switch 132 is provided at one end of the circuit board 130 close to the upper bracket 121. The handle housing 110 is provided with a pressing portion 112 corresponding to the micro switch 132. The button 170 is connected to the side of the pressing portion 112 away from the micro switch 132. The micro switch 132 is electrically connected to the lamp beads 131.

[0053] As Figure 2As shown, in an embodiment of the present utility model, a microswitch 132 is disposed on a side of the circuit board 130 facing away from the upper bracket 121. The microswitch 132 is electrically connected to the lamp bead 131. A pressing portion 112 is provided on the handle housing 110 corresponding to the microswitch 132. The pressing portion 112 is connected to the housing to form a closed structure and forms an installation groove on the outer surface of the handle housing 110. The button 170 is disposed in the groove. By pressing the button 170, the pressing portion 112 deforms towards the inner wall of the housing to trigger the microswitch 132. A controller (not shown) is also provided on the circuit board 130, which is configured to receive a signal emitted by the microswitch 132 and control the lamp bead 131 to be lit or extinguished according to the signal. By disposing the button 170 at the upper end of the handle housing 110 away from the lamp bead 131, it is avoided that the human hand blocks the light when holding the handle housing 110, thereby improving the practicability.

[0054] In an embodiment, a limiting portion 1211 is provided on the upper bracket 121, and a buckle 1222 and a limiting post 1223 are respectively provided on the lower bracket 122. A limiting hole 130b is formed on the circuit board 130. The limiting post 1223 is embedded in the limiting hole 130b. The limiting portion 1211 is connected to one end of the circuit board 130 close to the upper bracket 121, and the buckle 1222 is clamped to one end of the circuit board 130 close to the lower bracket 122.

[0055] As Figure 2 and Figure 6 As shown, in an embodiment of the present utility model, a limiting portion 1211 is provided on the upper bracket 121, and a limiting post 1223 and a buckle 1222 are provided on the lower bracket 122. A limiting hole 130b corresponding to the limiting post 1223 is formed on the circuit board 130. During installation, first, the end of the circuit board 130 provided with the microswitch 132 is snapped into the limiting portion 1211, then the limiting hole 130b on the circuit board 130 is aligned with the limiting post 1223 on the lower bracket 122, and the limiting post 1223 is embedded into the limiting hole 130b. The buckle 1222 on the lower bracket 122 simultaneously clamps the circuit board 130 to fix the circuit board 130 on the bracket 120. As can be seen from the above, by providing the limiting portion 1211, the buckle 1222 and the limiting post 1223, the rapid assembly of the circuit board 130 and the bracket 120 can be realized, and the production efficiency can be improved.

[0056] The present utility model also provides an electric toothbrush. The electric toothbrush 1 includes an electric toothbrush display structure 100. The specific structure of the electric toothbrush display structure 100 refers to the above embodiments. Since the electric toothbrush 1 adopts all the technical solutions of the above all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one.

[0057] The electric toothbrush 1 includes a handle portion 10, a brush head 20, and a charging stand 30. The electric toothbrush display structure 100 is disposed inside the handle portion 10. The electric toothbrush 1 further includes a motor assembly 11, a sealing assembly 12, and a bottom cover assembly 13.
