[0038] The utility model will be further described below in combination with specific embodiments and drawings, more details are set forth in the following description in order to fully understand the utility model, but the utility model can obviously be implemented in many other ways different from this description, and those skilled in the art can make similar generalization, deduction according to actual application without departing from the connotation of the utility model, therefore the protection scope of the utility model should not be limited by the content of this specific embodiment.

[0039] Figure 1 The utility model discloses a toothbrush's sectional view is shown, Figure 2 The utility model discloses a toothbrush's sectional view is shown, Figure 1 The utility model discloses a toothbrush's sectional view is shown,

[0040] The utility model discloses a toothbrush's sectional view is shown, Figure 1 As shown in the toothbrush, including toothbrush head 1, connecting rod 2 and the toothbrush handle 3 with internal space 31, the first end 21 of connecting rod 2 is fixedly connected with toothbrush head 1, and the second end 22 of connecting rod 2 extends into internal space 31;Internal space 31 is provided with pressure alarm (not shown). In the prior art, toothbrush head 1 is pressed and often drives connecting rod 2 to deform or displace, thereby triggering the pressure alarm. But sometimes toothbrush head 1 is also affected by external force when not brushing (such as toothbrush dumping, toothbrush transportation process) and triggers the alarm incorrectly, causing trouble to the user.

[0041] Therefore, the utility model still sets up human body induction component 4 in internal space 31, and connecting rod 2 contacts human body induction component 4 when the pressure value that toothbrush head 1 receives is greater than the preset value;Human body induction component 4 informs the pressure alarm after being contacted by connecting rod 2 and receiving human body characteristic signal;Wherein, the human body characteristic signal is the signal generated by human body contacting toothbrush. Therefore, the prerequisite of triggering the pressure alarm in the utility model has two: one is that the pressure value that toothbrush head 1 receives is greater than the preset value, and two is that human body contacts the toothbrush. Thus, the pressure alarm false triggering caused by other accidental conditions is avoided, and the user experience is improved.

[0042] The subsequent embodiments will further illustrate the principles and applications of the utility model.

[0043] According to one exemplary embodiment of the utility model, the connecting rod 2 includes a first conductive module (not shown), which outputs a first human body characteristic signal when a human body contacts the connecting rod 2, and the human body induction component 4 receives the first human body characteristic signal through contact with the connecting rod 2. Specifically, the connecting rod 2 is partially exposed to the outer surface of the toothbrush head 1, and when the toothbrush head 1 enters the user's mouth, the human body will also contact the connecting rod 2, especially the first conductive module of the connecting rod 2, and transmit an electrical signal. The first conductive module senses the contact of the human body and outputs the first human body characteristic signal. In the utility model, the first conductive module can be part of the connecting rod 2 or the entire connecting rod 2 itself, which is not limited here.

[0044] Regarding the connecting rod 2 or the first conductive module, in an alternative embodiment, the surface thereof is covered with a fine conductive wire mesh, when the oral cavity contacts the surface, a capacitance is formed between the human body and the mesh and a slight charge change is caused near the contact position, the first conductive module can sense the change and output the first human characteristic signal.

[0045] In other alternative embodiments, the connecting rod 2 has no part exposed to the outer surface of the brush head 1, i.e. the first conductive module has no direct contact with the human body, when the brush head 1 enters the oral cavity of the user, the first conductive module senses the change of the micro electric field of the human body and outputs the first human characteristic signal.

[0046] According to an exemplary embodiment of the present application, the brush head 1 comprises a first conductive module, the first conductive module outputs the first human characteristic signal when the human body contacts the brush head 1 and transmits to the connecting rod, the human body sensing assembly 4 receives the first human characteristic signal through the contact with the connecting rod. Specifically, the first conductive module should be arranged at a position of the brush head 1 which is easy to contact the human body, and the brush head 1 and the connecting rod 2 should have electrical connection to transmit the first human characteristic signal.

[0047] According to an exemplary embodiment of the present application, as shown in Figure 1 , the brush head 1 comprises a head 11 planted with tooth cleaning elements 5, and a neck 12 connecting the head 11 and the brush handle 3; the first end portion 21 is inserted into the neck 12. Optionally, the neck 12 is provided with a mounting hole near the end close to the brush handle 3 for inserting the connecting rod 2, the first end portion 21 is preferably in interference fit with the mounting hole, the pressure on the neck 12 by the user during brushing and the resulting deformation can be better transmitted to the connecting rod 2. Optionally, the neck 12 is provided with a containing space for placing the connecting rod 2, and a cover plate covering the containing space after the connecting rod 2 is placed, the opening of the containing space can be directed to the outer surface of the brush in any direction, which is not limited here.

[0048] According to an exemplary embodiment of the present application, as shown in Figure 1 and Figure 2 , the brush comprises a front surface S1 planted with tooth cleaning elements 5 and a rear surface S2 opposite to the front surface; the human body sensing assembly 4 is closer to the front surface S1 relative to the second end portion 22 in the internal space 31. It can be understood that the pressure of the teeth on the brush head 1 during brushing by the user is mainly directed to the rear surface S2, the force on the first end portion 21 is also directed to the rear surface S2, due to the lever effect, the second end portion 22 at the other end moves towards the front surface S1, and the human body sensing assembly 4 is arranged at a position closer to the front surface S1, which is conducive to the contact between the second end portion 22 and the human body sensing assembly 4.

[0049] According to one exemplary embodiment of the present utility model, the human body sensing component 4 comprises a conductive sheet 41 and a control board 42; the conductive sheet 41 receives the first human body characteristic signal through contact with the second end portion 22 and transmits it to the control board 42. The arrangement of the conductive sheet 41 makes it unnecessary for the control board 42 to be in direct contact with the second end portion 22, providing flexibility for the arrangement of the internal space 31 structure of the toothbrush handle 3.

[0050] In other alternative embodiments, the conductive sheet 41 can also be part of the connecting rod 2, which can play a role in transmitting electrical signals between the second end portion 22 and the control board 42.

[0051] Further, the conductive sheet 41 is made of a flexible conductive material. Generally, the control board 42 is a conventional hard circuit board, and the second end portion 22 is usually in rigid contact with the control board 42, which is not conducive to achieving good electrical connection on the one hand, and long-term frequent rigid contact can easily cause part wear on the other hand. The conductive sheet 41 made of a flexible conductive material is conducive to improving this situation.

[0052] Further, the control board 42 is provided with a touch chip 43; after receiving the first human body characteristic signal, the touch chip 43 converts it into a digital signal and alarms the pressure alarm 4.

[0053] According to one exemplary embodiment of the present utility model, as shown in Figure 3 The toothbrush handle 3 comprises a second conductive module 32; the second conductive module 32 outputs the second human body characteristic signal when the human body contacts the toothbrush handle 3 and transmits it to the human body sensing component 4; the human body sensing component 4 notifies the pressure alarm after being contacted by the connecting rod 2 and simultaneously receiving the first human body characteristic signal and the second human body characteristic signal. It can be understood that the second conductive module 32 should be electrically connected with the toothbrush handle 3 or partially exposed to the outside of the toothbrush handle 3 to receive electrical signals from the human body when the user holds the toothbrush handle 3. Taking the human body contacting the toothbrush head 1 and the toothbrush handle 3 at the same time as the premise of triggering the pressure alarm is to simulate the actual scene of the user brushing teeth, further improving the accuracy of preventing false triggering.

[0054] According to one exemplary embodiment of the present utility model, the toothbrush further comprises a power supply 6 electrically connected with the human body sensing component 4 and the pressure alarm 4. Thus, the pressure alarm system of the toothbrush is provided with power support.

[0055] According to one exemplary embodiment of the present utility model, the power supply 6 is a dry battery.
