Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, a toothbrush according to the present invention is shown, which comprises: the toothbrush comprises a toothbrush head 1 and a toothbrush handle 2 which are connected with each other, wherein the toothbrush head 1 is provided with a first outlet 11; the toothbrush handle 2 comprises a toothpaste chamber 21 for storing toothpaste 216; the toothpaste bin 21 comprises a second outlet 211 and a pushing device 212 for pushing toothpaste 216; wherein the second outlet 211 is connected with the first outlet 11 through a connecting device 23, and the connecting device 23 is hollow; the pushing means 212 is moved toward the second outlet 211 by the force to push the toothpaste 216 to the toothbrush head 1 through the second outlet 211, the connecting means 23 and the first outlet 11.

It should be noted that the first outlet 11 is disposed at the bristle 13 side of the toothbrush head 1, and the toothpaste 216 in the toothpaste chamber 21 can reach the side of the bristle 13 contacting with the teeth through the first outlet 11. Since the bristles 13 have a certain height, in order to make it easier for the toothpaste 216 to reach the bristles 13, a connection part may be provided at the first outlet 11, which is close to the height of the bristles 13, and is disposed in a direction parallel to the direction of the bristles 13. Optionally, the connecting member is made of a flexible material.

Optionally, the pushing device 212 is a piston.

According to the toothbrush provided by the utility model, the second outlet of the toothpaste bin is connected with the first outlet of the toothbrush head, so that a user only needs to apply force to the pushing device in the toothpaste bin under the condition of tooth brushing requirement, the pushing device pushes toothpaste in the toothpaste bin to be automatically extruded out, and the extruded toothpaste reaches the bristles of the toothbrush head through the hollow connecting device. In this way, the user does not need to hold the toothpaste bottle and manually apply the toothpaste to the bristles of the toothbrush head. For a user, the mode of applying the toothpaste provided by the utility model is more friendly, the operation is simpler and more convenient, and the use experience of the user can be improved.

Further, the user can adjust the amount of toothpaste squeezed out by adjusting the amount of force applied to the pushing device 212 or the time of the force applied to the pushing device 212 according to individual needs.

Illustratively, the toothbrush further comprises: a power generation device 24, wherein the power generation device 24 is connected to the pushing device 212, wherein the power generation device 24 applies force to the pushing device 212; a first switch 25, wherein the first switch 25 is connected with the power generation device 24; the first switch 25 sends a first activation signal to the power generation device 24, and the power generation device 24, upon receiving the first activation signal, applies a force to the pushing device 212.

It should be noted that when the user needs to brush teeth, the power generating device 24 applies a force to the pushing device 212 by pressing the first switch 25, and the force acts on the pushing device 212 to displace the pushing device 212, so that the toothpaste in the toothpaste bin 21 can be continuously extruded to the first outlet 11 and to the side of the bristles 13 contacting with the teeth.

When the amount of toothpaste at the bristles 13 meets the user's requirements, the user presses the first switch 25, the first switch 25 sends a first stop signal to the power generation device 24, and the power generation device 24 stops applying force to the pushing device 212 when receiving the first stop signal. At this time, the toothpaste in the toothpaste container 21 is no longer pushed out by the pushing device 212.

In another embodiment, the user may keep the first switch 25 pressed by pressing the first switch 25 for a long time. When the first switch 25 is kept pressed, the toothpaste in the toothpaste chamber 21 is continuously extruded by the pushing device 212, and when the user releases the first switch 25, that is, the first switch 25 is no longer in the pressed state, the toothpaste in the toothpaste chamber 21 is no longer extruded by the pushing device 212.

Through the first switch 25 and the power generation device 24, a user can conveniently paint toothpaste on the bristles 13, the operation can be realized by one hand, and the operation process is simple.

Optionally, the toothbrush further comprises a power source connected to the first switch 25 and the power generation device 24, respectively. The power source provides electrical power to the power generation device 24 such that when the first switch 25 is depressed, the power generation device 24 generates a force under the electrical power to apply the generated force to the pushing device 212.

By way of example, the power generation device 24 comprises: an air pump; a first air inlet 213 is arranged on the toothpaste bin 21, and the first air inlet 213 is connected with the air pump through a first pipeline 26; the air pump injects air into the toothpaste bin 21 through the first pipe 26 and the first air inlet 213, and the thrust generated by the air acts on the pushing device 212.

It should be noted that, when the air pump is in an operating state, air is generated. The generated gas enters the first gas inlet 213 of the toothpaste bin 21 through the first pipe 26. The gas entering the first gas inlet 213 may generate a thrust force under the action of the gas pump, such that the thrust force acts on the thrust device 212 to displace the thrust device 212.

Referring next to fig. 2, for example, a second pipe 214 and a toothpaste accommodating space are disposed in the toothpaste bin 21, a first air inlet 213 of the second pipe 214 is connected to a first air outlet of the first pipe 26, the pushing device 212 is located at a second air outlet 215 of the second pipe 214, and the pushing device 212 is a space surface of the toothpaste accommodating space.

It should be noted that the pushing device 212 is a space surface of the toothpaste accommodating space, and the toothpaste accommodating space is not communicated with the outside under the space surface.

The pushing device 212 is located at the second gas outlet 215 of the second duct 214, so that the gas passing through the second gas outlet 215 of the second duct 214 generates a pushing force acting on the pushing device 212, thereby generating a displacement of the pushing device 212. Thereby pushing the toothpaste in the toothpaste chamber 21 to flow out of the second outlet 211 and finally reach the toothbrush head 1.

Illustratively, the toothbrush further comprises: the detection circuit is connected with the air pump; and the detection circuit sends a signal for stopping working to the air pump when detecting that the electric signal generated when the air pump works is larger than a set threshold value.

Alternatively, the electrical signal may be a current signal, a voltage signal, or a resistance signal.

It should be noted that the toothpaste in the toothpaste chamber 21 is consumed as the number of uses of the toothpaste by the user increases. After the toothpaste is consumed, if the user still pushes the toothpaste by turning on the air pump during brushing teeth, the pushing device 212 cannot displace even under the action of the pushing force because the toothpaste in the toothpaste bin 21 is consumed. But the gas in the toothpaste chamber 21 is rapidly filled. After the gas is continuously injected, the gas pressure in the toothpaste chamber 21 is rapidly increased. In order to continue to inject gas into the toothpaste chamber 21, the motor of the air pump needs to operate with a larger power. However, the power supply voltage is constant, the working current required by the motor of the air pump is increased, and if the working current exceeds the preset current value, the toothpaste in the toothpaste bin 21 is considered to be completely consumed. By signaling the air pump to stop functioning, damage to the air pump or other components of the toothbrush can be prevented.

Optionally, the toothbrush further comprises an alarm device connected to the detection circuit. The prompting device can be an indicator light or a buzzer. The prompting device is mounted on the toothbrush handle 2. And when the detection circuit detects that the electric signal generated when the air pump works is greater than a set threshold value, an alarm signal is sent to the prompting device. After the prompting device receives the alarm signal, the indicating lamp can be turned on or the buzzer sounds, so that the attention of a user is attracted, and the user can replenish the toothpaste in the toothpaste bin 21 in time according to the prompt.

Illustratively, a first one-way valve 12 is arranged between the first outlet 11 and the connecting device 23, and the conducting direction of the first one-way valve 12 is as follows: from the connecting means 23 towards the first outlet 11 the first one-way valve 12 is located in the toothbrush head 1.

It should be noted that, by providing the first one-way valve 12 between the first outlet 11 and the connecting device 23, the toothpaste squeezed out from the bristles 13 can be prevented from being sucked back into the connecting device 23, and the user can not experience the toothpaste badly.

Illustratively, the toothbrush further comprises: the motor 27, the said motor 27 is connected with said junction device 23; the motor 27 drives the bristles 13 on the toothbrush head 1 to vibrate through the connecting device 23; a second switch 28, wherein the second switch 28 is connected with the motor 27; the second switch 28 sends a second start signal and a second stop signal to the motor 27, the motor 27 operates when receiving the second start signal, and the motor 27 stops operating when receiving the second stop signal.

It should be noted that when the user needs to brush teeth, the motor 27 can be operated (i.e. the motor 27 receives the second start signal) by pressing the second switch 28, so that the motor 27 vibrates according to a certain frequency. The motor 27 drives the bristles 13 of the toothbrush head 1 to vibrate through the connecting device 23 in an operating state, so that the vibrating bristles 13 can clean teeth.

When the user finishes brushing his/her teeth, the motor 27 can be deactivated (i.e., the motor 27 receives a second stop signal) by pressing the second switch 28 again.

Optionally, the power supply is also connected to the second switch 28 and the motor 27, respectively. The power supply provides power to the motor 27 so that when the second switch 28 is pressed, the motor 27 can vibrate the bristles 13 on the brush head under the action of the power.

Illustratively, a cavity 14 is arranged in the toothbrush head 1, and a first end of the cavity 14 is connected with the first outlet 11; the connecting device 23 comprises a motor shaft 231 and a conduit 232 which are connected with each other; the outlet of the motor shaft 231 is connected with the second end of the cavity 14, the conduit 232 is connected with the toothpaste bin 21, the motor shaft 231 is connected with the motor, and the motor drives the bristles 13 to vibrate through the motor shaft 231.

Illustratively, a second one-way valve 29 is arranged between the conduit 232 and the toothpaste bin 21, and the conduction direction of the second one-way valve is as follows: from the paste cartridge 21 towards the conduit 232.

It should be noted that by providing the second one-way valve 29, the toothpaste that has entered the conduit 232 is prevented from being sucked back into the toothpaste chamber 21. Connection of paste cartridge 21 to conduit 232 may also be accomplished through second one-way valve 29.
