Detailed Description

The embodiments of the invention are described in detail below, but the invention can be implemented in many different ways, which are defined and covered by the claims.

As an aspect of the present invention, there is provided a toothbrush, including: brush head 1, handle 2 and power 3, handle 2 includes handle casing 4, heating switch 5 and is used for the heating the freeze-proof device 6 of handle casing 4, freeze-proof device 6 includes heating element 7, brush head 1 with the top of handle 2 is connected, heating element 7 heating switch 5 is all fixed on handle casing 4, heating switch 5 with freeze-proof device 6 electricity is connected, power 3 set up in handle casing 4 and with freeze-proof device 6 electricity is connected.

Preferably, the heating element 7 is a flexible thin film heating sheet. Because the space of the toothbrush is limited, the flexible film heating sheet is used, the space can be saved, and the toothbrush can be better attached to other surfaces, thereby being beneficial to heat conduction.

Wherein the power supply 3 supplies the anti-freeze 6. In a low-temperature environment, a user can touch the heating switch 5 on the handle to start the anti-freezing device 6, the temperature of the heating element 7 on the anti-freezing device 6 is rapidly increased, so that the temperature of the heat transfer area 17 is rapidly increased, and the user does not feel cold when holding the exposed heat transfer area 17. If the heating is stopped in advance or the heating is stopped after the teeth are brushed, the heating switch 5 can be triggered again to stop heating the heating element 7.

In one embodiment, as shown in fig. 2, the heating element 7 is preferably disposed on the outer surface of the handle housing 4, and the handle housing 4 is preferably made of a material with low thermal conductivity, such as ABS or ABS + PC. The heating element 7 is directly fixed on the surface of the handle shell 4, and a user can directly contact the heating element 7, so that the transmission speed is higher, and the waiting heating time of the user is reduced. The handle housing 4 is made of a material with low thermal conductivity, so that heat loss can be reduced.

In another embodiment, as shown in fig. 3, the heating element 7 is preferably disposed on the inner surface of the handle housing 4, and the handle housing 4 is preferably made of a high thermal conductivity material, such as aluminum. The heating element 7 is disposed on the inner surface of the handle case 4, and can be protected by the handle case 4. The handle shell 4 is made of high-heat-conductivity materials, so that the heating element 7 can transfer heat to the whole shell, the area of the heat transfer area 17 can be enlarged, a user can hold the heat transfer area indiscriminately, and the user is relieved and does not need to identify the position or the area of the heat transfer area.

Preferably, as shown in fig. 4, the handle housing 4 includes a first housing 8 and a second housing 9, the first housing 8 is sleeved outside the second housing 9, and the heat conduction capacity of the first housing 8 is lower than that of the second housing 9. In this embodiment, the heating element 7 is in direct contact with only the portion of the second housing 9 in the handle housing 4, and not with the portion of the first housing 8. Therefore, the heating element 7 is not exposed, the heating element 7 is protected, the safety is high, and the service life is longer; the heat conduction can be centralized, the heat loss is reduced, the waiting heating time of a user is further reduced, and in addition, the heat generation of the heat conduction area 17 is more uniform.

In a preferred embodiment, the anti-freezing device 6 further comprises a controller, the controller comprises a control unit and a current limiting module for detecting the current of the heating element 7, and the power supply 3 is electrically connected with the heating element 7 sequentially through the current limiting module and the control unit. As the temperature of the heating element 7 increases, the resistance decreases and the current increases. Therefore, when the user touches the heating switch 5, the resistance of the heating element 7 decreases and the current increases as the temperature increases. When the current reaches the set value, the current limiting module gives a signal to the control unit, reduces the current of the control unit, increases the resistance, reduces the heating, finally reaches a balance, realizes the indirect temperature control by controlling the current, and prevents the overhigh temperature. The temperature control is performed through the current, which belongs to the prior art and is not described herein again.

In the embodiment shown in fig. 5, preferably, the anti-freezing device 6 further includes a controller 10 and a temperature sensor 11 for detecting the temperature of the heating element 7, the controller 10 is disposed in the handle housing 4, the controller includes a control unit and a temperature control module, the power supply 3 is electrically connected to the heating element 7 sequentially through the temperature control module and the control unit, and the temperature sensor 11 is electrically connected to the temperature control module. In this embodiment, the heating element 7 conducts heat to the temperature sensor 11, the temperature sensor 11 feeds back the heat to the temperature control module after collecting the temperature, the temperature control module identifies whether the temperature reaches a set value, if so, the temperature is sent to the control unit, and the control unit stops supplying power to the heating element for heating; the temperature of the heating element can slowly drop, the temperature sensor continues to transmit the collected temperature to the temperature control module, and when the temperature reaches another set value, the controller can start the heating element again. Therefore, accurate temperature control is realized, and the handle is held by the hand more comfortably. The temperature control is performed through temperature feedback, which belongs to the prior art and is not described herein again.

In another preferred embodiment, the anti-freeze apparatus 6 further comprises a controller 10, the controller 10 is disposed in the handle housing 4, the controller 10 comprises a control unit and a timing module, and the power supply 3 is electrically connected to the heating element 7 through the timing module and the control unit in sequence. After the heating switch is touched, the control module starts the heating element 7, the timing module starts timing, the heating element works to the time value set by the timing module, the electric connection between the heating element and the power supply is automatically cut off, the heating element stops working, and the phenomenon that the anti-freezing device is forgotten to be turned off and electricity is wasted after the product is used up is prevented. The heating time is controlled by a timer to realize automatic power-off, which belongs to the prior art and is not described herein again.

As shown in fig. 2, preferably, a groove 12 is formed at the bottom of the brush head 1, a protrusion 13 is formed at the top of the handle housing 4, and the brush head 1 and the handle housing 4 are connected in a pluggable manner through a plug-in structure between the groove 12 and the protrusion 13. Because the brush head 1 and the handle 2 are rigidly connected with the groove 12 on the brush head 1 through the convex block 13 on the handle 2, the teeth can be brushed by the brush head through holding the heat transfer area by hand. Therefore, only the brush head can be replaced regularly, and the brush head is economical and practical.

As shown in fig. 6, preferably, the handle 2 further includes a sonic vibration motor 14, a bracket 15 and a motor switch 16, the sonic vibration motor 14 and the power source 3 are both fixed on the bracket 15, the bracket 15 is fixed in the handle housing 4, and the sonic vibration motor 14 is electrically connected to the power source 3 and the motor switch 16, respectively. The power supply 3 supplies power to the sound wave vibration motor 14, a user can touch the motor switch 16 to start the sound wave vibration motor 14, and the sound wave vibration motor 14 rotates forwards and backwards, so that the whole handle shell 4 is driven to vibrate, the user can feel numb when holding the temperature sensing area 17, the freezing sense is reduced, and the anti-freezing effect is finally achieved. The vibration of the motor and the heating element work at the same time, and the anti-freezing effect is better.
