Description

Technical Field

[0001] The invention relates to the field of personal hygiene products, in particular to a toothbrush. Background Art

[0002] When a user uses a toothbrush, the brush head needs to be close to the surface of the teeth. When the user presses the toothbrush hard, the excessive pressure plus the high-frequency friction of the bristles may cause damage to the teeth and easily cause gum bleeding and wedge-shaped wear of the teeth, which are harmful to health. At present, there are many toothbrushes with pressure reminder functions on the market.

[0003] However, sometimes the brush head may be affected by external force and erroneously trigger an alarm at non-brushing times (such as when the toothbrush falls over or is being transported), causing trouble to the user. Therefore, a toothbrush that can prevent the pressure alarm function from being erroneously triggered is needed. Summary of the invention

[0004] The present invention provides a toothbrush, which includes a toothbrush head, a connecting rod, and a toothbrush handle with an internal space, wherein the first end of the connecting rod is fixedly connected to the toothbrush head, and the second end of the connecting rod extends into the internal space; the internal space is provided with a human body sensing component and a pressure alarm; the connecting rod is constructed to contact the human body sensing component when the pressure value applied to the toothbrush head is greater than a preset value; the human body sensing component notifies the pressure alarm to alarm after being contacted by the connecting rod and receiving a human body characteristic signal; wherein the human body characteristic signal is a signal generated by a human body contacting the toothbrush.

[0005] The setting of the human body sensing component makes human body contact with the toothbrush a prerequisite for triggering the pressure alarm. The toothbrush will no longer mistakenly trigger the alarm simply because of pressure, thereby improving the user experience.

[0006] According to one aspect of the present invention, the connecting rod includes a first conductive module; the first conductive module outputs a first human body characteristic signal when a human body contacts the connecting rod; the human body sensing component receives the first human body characteristic signal by contacting the connecting rod. Thus, the corresponding human body characteristic signal is transmitted to the human body sensing component through the connecting rod by the first conductive module.

[0007] According to one aspect of the present invention, the toothbrush head includes a first conductive module; when a human body contacts the toothbrush head, the first conductive module outputs a first human characteristic signal and transmits it to the connecting rod; the human body sensing component receives the first human characteristic signal by contacting the connecting rod. Thus, when a human body contacts the toothbrush head, the first conductive module transmits the corresponding human characteristic signal to the human body sensing component via the connecting rod.

[0008] According to one aspect of the present invention, the toothbrush head comprises a head with teeth cleaning elements implanted therein, and a neck connecting the head and the toothbrush handle; the first end portion is arranged on the neck portion, so that when the user brushes his teeth, the pressure on the neck portion and the deformation caused thereby can be better transmitted to the first end portion.

[0009] According to one aspect of the present invention, the toothbrush comprises a front surface on which the tooth cleaning element is implanted and a rear surface opposite to the front surface; the human body sensing component is closer to the front surface than the second end in the internal space. When the user brushes his teeth, the second end tends to move toward the front surface due to the lever effect of the force, and such a positional relationship is conducive to better contact between the human body sensing component and the second end.

[0010] According to one aspect of the present invention, the human body sensing component includes a conductive sheet and a control board; the conductive sheet receives the first human body characteristic signal through contact with the second end and transmits it to the control board. The provision of the conductive sheet makes it unnecessary for the control board to be in direct contact with the second end, providing flexibility for the arrangement of the internal space structure of the toothbrush handle.

[0011] According to one aspect of the present invention, the conductive sheet is made of a flexible conductive material, so that the non-rigid contact between the conductive sheet and the second end portion is beneficial to improving the durability of the component.

[0012] According to one aspect of the present invention, a touch chip is provided on the control board; after receiving the first human characteristic signal, the touch chip notifies the pressure alarm to alarm. The touch chip processes the received signal and notifies the execution.

[0013] According to one aspect of the present invention, the toothbrush handle includes a second conductive module; when a human body contacts the toothbrush handle, the second conductive module outputs a second human characteristic signal and transmits it to the human body sensing component; after the human body sensing component is contacted by the connecting rod and simultaneously receives the first human characteristic signal and the second human characteristic signal, it notifies the pressure alarm to alarm. The premise of triggering the pressure alarm is that the toothbrush head and the toothbrush handle are contacted by the human body at the same time, which further improves the accuracy of preventing false triggering.

[0014] According to one aspect of the present invention, the toothbrush further comprises a power supply electrically connected to the human body sensing component and the pressure alarm, thereby providing power support for the pressure alarm system of the toothbrush.

[0038] The present invention is further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description herein. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0039] Figure 1 1 shows a cross-sectional view of a toothbrush according to a preferred embodiment of the present invention, and Figure 2 Shows Figure 1 A partial enlarged view of part A.

[0040] like Figure 1 The toothbrush shown includes a toothbrush head 1, a connecting rod 2, and a toothbrush handle 3 with an internal space 31. The first end 21 of the connecting rod 2 is fixedly connected to the toothbrush head 1, and the second end 22 of the connecting rod 2 extends into the internal space 31; the internal space 31 is provided with a pressure alarm (not shown). In the prior art, the pressure on the toothbrush head 1 often causes the connecting rod 2 to deform or move, thereby triggering a pressure alarm. However, sometimes the toothbrush head 1 may be affected by external forces at non-brushing times (such as when the toothbrush falls over or is being transported), and the alarm may be triggered by mistake, causing trouble to the user.

[0041] To this end, the present invention further provides a human body sensing component 4 in the internal space 31, and the connecting rod 2 contacts the human body sensing component 4 when the pressure value on the toothbrush head 1 is greater than a preset value; the human body sensing component 4 notifies the pressure alarm to alarm after being contacted by the connecting rod 2 and receiving the human body characteristic signal; wherein the human body characteristic signal is a signal generated by the human body contacting the toothbrush. Therefore, there are two prerequisites for triggering the pressure alarm in the present invention: one is that the pressure value on the toothbrush head 1 is greater than the preset value, and the other is that the human body contacts the toothbrush. This avoids the false triggering of the pressure alarm that may be caused by other unexpected situations, and improves the user experience.

[0042] The following embodiments will further illustrate the principles and applications of the present invention.

[0043] According to an exemplary embodiment of the present invention, the connecting rod 2 includes a first conductive module (not shown), and the first conductive module outputs a first human characteristic signal when a human body contacts the connecting rod 2, and the human body sensing component 4 receives the first human characteristic signal by contacting the connecting rod 2. Specifically, the connecting rod 2 is partially exposed to the outer surface of the toothbrush head 1. 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 electrical signals. The first conductive module senses the contact of the human body and outputs the first human characteristic signal. In the present invention, the first conductive module can be either a 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 optional embodiment, its surface is covered with a layer of fine conductive wire grid. When the mouth touches its surface, a capacitor is formed between the human body and the grid and causes a tiny charge change near the contact position. The first conductive module can sense this change and output a first human body characteristic signal.

[0045] In other alternative embodiments, the connecting rod 2 has no portion exposed to the outer surface of the toothbrush head 1, that is, the first conductive module has no direct contact with the human body. When the toothbrush head 1 enters the user's mouth, the first conductive module senses the change in the human body's micro-electric field and outputs a first human characteristic signal.

[0046] According to an exemplary embodiment of the present invention, the toothbrush head 1 includes a first conductive module, which outputs a first human characteristic signal and transmits it to the connecting rod when the human body contacts the toothbrush head 1, and the human body sensing component 4 receives the first human characteristic signal by contacting the connecting rod. Specifically, the first conductive module should be arranged at a position of the toothbrush head 1 that is easy to contact the human body, and the toothbrush head 1 and the connecting rod 2 should be electrically connected to transmit the first human characteristic signal.

[0047] According to an exemplary embodiment of the present invention, Figure 1 As shown, the toothbrush head 1 includes a head 11 implanted with a tooth cleaning element 5, and a neck 12 connecting the head 11 and the toothbrush handle 3; the first end 21 is inserted into the neck 12. Optionally, the neck 12 is provided with a mounting hole for inserting the connecting rod 2 at one end close to the toothbrush handle 3, and the first end 21 and the mounting hole are preferably interference fit, so that the pressure and deformation caused by the user on the neck 12 when brushing teeth can be better transmitted to the connecting rod 2. Optionally, the neck 12 is provided with a receiving space for placing the connecting rod 2, and a cover plate for covering the above-mentioned receiving space after the connecting rod 2 is placed. The opening of the receiving space can face the outer surface of the toothbrush in any direction, which is not limited here.

[0048] According to an exemplary embodiment of the present invention, Figure 1 and Figure 2 As shown, the toothbrush includes a front surface S1 with a tooth cleaning element 5 and a rear surface S2 opposite to the front surface; the human body sensing component 4 is closer to the front surface S1 than the second end 22 in the internal space 31. It can be understood that when the user brushes his teeth, the pressure of the teeth on the toothbrush head 1 is mainly toward the rear surface S2, and the force of the first end 21 is also toward the rear surface S2. Due to the lever effect, the second end 22 at the other end moves toward the front surface S1, and the human body sensing component 4 is set at a position closer to the front surface S1, which is conducive to the contact between the second end 22 and the human body sensing component 4.

[0049] According to an exemplary embodiment of the present invention, the human body sensing component 4 includes a conductive sheet 41 and a control board 42; the conductive sheet 41 receives the first human body characteristic signal by contacting the second end 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 directly contact the second end 22, which provides flexibility for the arrangement of the structure of the internal space 31 of the toothbrush handle 3.

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

[0051] Furthermore, 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 22 is usually in rigid contact with the control board 42, which is not conducive to achieving a good electrical connection on the one hand, and on the other hand, long-term and frequent rigid contact is prone to cause parts wear. The conductive sheet 41 made of a flexible conductive material is conducive to improving this situation.

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

[0053] According to an exemplary embodiment of the present invention, Figure 3 As shown, the toothbrush handle 3 includes a second conductive module 32; the second conductive module 32 outputs a second human characteristic signal and transmits it to the human sensing component 4 when the human body contacts the toothbrush handle 3; the human sensing component 4 notifies the pressure alarm to alarm after being contacted by the connecting rod 2 and receiving the first human characteristic signal and the second human characteristic signal at the same time. It can be understood that the second conductive module 32 should be electrically connected to 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 simultaneous contact of the toothbrush head 1 and the toothbrush handle 3 by the human body as the premise for triggering the pressure alarm is to simulate the actual scene of the user brushing his teeth, which further improves the accuracy of preventing false triggering.

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

[0055] According to an exemplary embodiment of the present invention, the power supply 6 is a dry cell battery.

[0056] Although the present invention is disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, any modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the protection scope defined by the claims of the present invention.
