The tooth stress area and the tongue and lip stress area 14 are each provided with at least one capsule type detection structure 2.

[0039] The detector, when measuring the tooth occlusion force, the tooth stress area of the main body 1 is stretched between the upper and lower teeth of the detected person, and the detected person starts to occlude, so that the chambers 21 of the capsule type detection structure 2 of the tooth stress area are extruded, the pressure value of the overall chamber formed by the chambers 21 changes and is detected by the pressure sensor, the pressure signal is analyzed, and then the force data of tooth occlusion can be measured; when measuring the tongue force of tongue against palate, the tongue-lip stress area 14 of the main body 1 is placed on the front area of the upper surface of the tongue of the detected person, the detected person performs tongue movement in the direction of top palate, so that the force data can also be obtained through the capsule type detection structure 2 of the area; similarly, when measuring the lip pressing force, the tongue-lip stress area 14 of the main body 1 is also stretched between the upper lip and the lower lip of the detected person, the detected person performs the lip pressing action, and then the lip pressing force can be measured.

[0040] The utility model discloses can measure tooth occlusion force, lip pressing force and tongue force in the direction of top palate, has simple structure, safe and sanitary, high comfort, reliable measurement, convenient operation, clean and can be repeatedly used etc.

[0041] In the utility model, the elastic material that main body 1 adopts, for example can be silica gel, nylon or polyurethane elastomer (TPU), the utility model does not make special limit, main body 1 can set the size of different size according to different human oral cavity biological data, and the chamber 21 in different stress area can also be designed and arranged according to human oral cavity biological data.

[0042] In an embodiment, the tooth stress area of the main body 1 includes left tooth stress area 11, right tooth stress area 12 and front tooth stress area 13, the tongue-lip stress area 14 is located between the left tooth stress area 11 and the right tooth stress area 12, and the left tooth stress area 11, the right tooth stress area 12, the front tooth stress area 13 and the tongue-lip stress area 14 are respectively provided with one capsule type detection structure 2. By designing in this way, the occlusion force of the teeth on both sides and the front teeth can be measured in zones, and when in use:

[0043] The capsule type detection structure 2 of the left tooth stress area 11 corresponds to the contact area of the first premolar to the second molar or the third molar on the left side of the human body;

[0044] The capsule type detection structure 2 of the right tooth stress area 12 corresponds to the contact area of the first premolar to the second molar or the third molar on the right side of the human body;

[0045] The capsule type detection structure 2 of the front tooth stress area 13 corresponds to the contact area between the canine tooth on the left side and the canine tooth on the right side of the human body.

[0046] The force area is divided according to the human oral biological data, information of the corresponding area is collected as much as possible, and the accuracy of the measurement data is improved.

[0047] In an embodiment, the cavities 21 arranged in the tooth force area are spherical and distributed in a honeycomb shape. In this design, considering the size of the human bite force and the elasticity of the material, the overall cavity formed by the plurality of cavities is more uniform in dispersing force when subjected to external force, avoiding the influence of the tooth biting position and the damage of the cavity by the tooth during measurement, and improving the stability of the overall cavity.

[0048] In an embodiment, the cavities 21 arranged in the tongue-lip force area 14 are columnar and distributed in parallel with each other. Considering the size of the tongue force and the lip force of the human top palate and the difference in the force position of the human body, the influence of the force position is avoided. In this design, the contact surface of the overall cavity formed by the plurality of cavities is increased, and the force information of the corresponding force area is collected as much as possible.

[0049] In an embodiment, in the capsule detection structure 2, each cavity 21 and each cavity 21 adjacent to the periphery are connected to each other through a branch pipe 22 opened on the main body 1. In this design, the fluid in the cavity 21 can flow more easily, and the pressure response is more sensitive. The capsule detection structure 2 further includes a main pipe 23 opened on the main body 1 and connected to the overall cavity formed by the plurality of cavities 21, and the pressure sensor is connected to the main pipe 23. In a specific implementation, the inlet end of the main pipe 23 can be connected to one or more cavities 21 and / or one or more branch pipes 22, and can be connected to the overall cavity formed by the plurality of cavities 21, so as to detect the pressure.

[0050] In an embodiment, the tooth force area and the tongue-lip force area 14 are located at the rear part of the main body 1, and the main pipe 23 of each capsule detection structure 2 extends to the front part of the main body 1. In this design, the rear part of the main body 1 is used to extend into the oral cavity, and the front part of the main body 1 is used to hold or connect the support body described below, which is more practical. Since the main pipe 23 extends to the front part of the main body 1, the influence of the change of the measurement force area is small, the force collection of the corresponding force area is not affected, the value is more accurate and reliable, and the pressure sensor can be installed at the outlet end of the main pipe 23.

In this way, the thickness between the surface of the main body 1 and the chambers 21 contacted by the corresponding teeth of the upper and lower jaws of the human body is ensured to be the same, so as to avoid inaccurate force information collection caused by the different stiffness of the upper and lower teeth contacting the corresponding regions of the main body 1 due to the thickness factor. More preferably, the middle sections of each branch pipe 22 and each main pipe 23 also coincide with the middle section of the main body 1.

[0052] In a specific implementation, the main body 1 can be formed into two halves in the middle section during manufacturing, and then bonded into a whole, so as to facilitate the formation of the chambers and the holes on the main body.

[0053] In an embodiment, the upper and lower sides of each capsule detection structure 2 in the tooth stress area in the main body 1 are respectively embedded with hard plates 16. The hard plates 16 are made of hard materials, such as plastic, iron sheet, etc. The setting of the hard plates 16 can make the biting force of the tooth stress area uniformly distributed to each chamber 21 of the corresponding capsule detection structure 2, avoid the damage of the chambers 21 caused by pressure concentration, avoid the influence of the biting position, and thus improve the stability of the overall chamber formed by the plurality of chambers.

[0054] In an embodiment, the upper and lower sides of the main body 1 corresponding to the tongue and lip stress areas 14 are designed in the shape of a wavy curved surface. In this way, the contact area of the upper surface of the human tongue and the lip with the chamber is increased, the force applied to the overall chamber formed by the plurality of chambers can be more accurately captured, and the position of the upper surface of the human tongue and the lip on the main body during measurement can also be facilitated to be prompted.

[0055] In an embodiment, the chambers 21 of the capsule detection structure 2 can be filled with gas, liquid or gas-liquid mixture by an external air pump, and the filling pressures of the capsule detection structures 2 of different stress areas can be the same or different, so as to change the bearing capacity of the capsule detection structures 2 of different stress areas, so that the bearing capacity of different stress areas is the same or different, so that the detector can measure a larger pressure. In addition, the pressure should be avoided to be too large to exceed the range of the signal acquisition module during measurement, so as to cause inaccurate measurement.

[0056] In an embodiment, the utility model also comprises a support body 3, and the main body 1 is detachably installed on the support body 3. In this way, the main body 1 can be easily disassembled for cleaning or replacement. In a specific implementation, the support body 3 can be a pistol-shaped handle structure or a long handle structure, and the utility model does not make special limitation as long as it is convenient to hold.

[0057] In an embodiment, the support body 3 is provided with a slot 31, the main body 1 is detachably inserted into the slot 31, the left and right sides of the main body 1 are respectively provided with a clamping groove 15, the left and right sides of the support body 3 are respectively hingedly connected with a button 32, one end of the button 32 is connected with the support body 3 through a spring 33, and the other end of the button 32 can be clamped into the corresponding clamping groove 15 under the elastic force of the spring 33 (the position of the corresponding clamping groove 15 on the support body 3 is provided with a gap hole for the button 32 to pass through). In this way, after the main body 1 is inserted, the button can position the main body 1 to improve stability. When disassembling, only the one end of the button needs to be pressed, and the other end of the button is pulled out of the clamping groove 15 to release the main body 1, and then the main body 1 can be removed.

[0058] In an embodiment, in order to realize the function of inflating the capsule type detection structure 2 to change the carrying capacity of the stress area, the support body 3 can be provided in a gas pump external or internal structure. The gas pump external handle structure uses a gas pipe to connect the gas pump and the main pipe of each stress area on the main body 1.

[0059] In a specific implementation, referring to Figure 8 A signal processing module can also be provided, which includes a signal conditioning unit, an analog-to-digital conversion unit and a communication unit. When the capsule type detection structure 2 is deformed under stress, the chamber 21 in the capsule type detection structure 2 is deformed under stress, the pressure is collected by the pressure sensor, and the pressure is converted into an electrical signal. By calibrating the corresponding relationship between the known pressure change and the output electrical signal change, the data size of the corresponding stress area can be obtained by measuring the electrical signal. The signal conditioning unit is used to obtain the force signal collected by the pressure sensor and convert the force signal into a conditioning signal. The analog-to-digital conversion unit is used to obtain the conditioning signal and convert it into a digital signal. The communication unit is used to obtain the digital signal and send it out through wired or wireless communication.
