For example, "A and / or B" includes A scheme, or B scheme, or A and B scheme.

[0032] Referring to Figures 1 to 6 .

[0033] In an optional embodiment of the present application, a bite force capsule type detector comprises:

[0034] The main body 1 is made of elastic material and is used for receiving tooth occlusion.

[0035] The capsule type detection structure is provided with a plurality of chambers 21 arranged in different regions of the main body 1 and a pressure sensor for measuring the overall chamber pressure formed by the plurality of chambers 21.

[0036] The detector of the present application is used by extending the main body 1 into the oral cavity of the detected person, and then the detected person bites with force to extrude the chambers 21 of the capsule type detection structure in the main body 1. In this way, the overall chamber pressure value formed by each chamber 21 will change and be detected by the pressure sensor. By analyzing the pressure signal, the bite force data can be measured. In the capsule type detection structure, each individual chamber 21 will affect the overall chamber pressure, so the chambers 21 bitten by different detected persons at different positions can be detected. The present application has better universality. In addition, different regions of the main body 1 are respectively provided with capsule type detection structures, so that the bite force of the teeth in different regions can be measured by the present application.

[0037] The elastic material used in the main body 1 of the present application can be, for example, silicone, nylon or polyurethane elastomer (TPU), polyethylene, polystyrene and other high molecular materials. The chambers 21 can be spherical or ellipsoidal or columnar. The chambers 21 of each capsule type detection structure can be arranged in one row or multiple rows. When the chambers in the left and right bite force stress areas are spherical or ellipsoidal or columnar, the chambers 21 in each row can be staggered. When the chambers 21 in the front bite force stress area are columnar, the chambers 21 in each row are parallelly distributed. The present application does not make special restrictions.

[0038] The main body 1 can be set to different sizes according to different human oral biological data, and the chambers 21 in different stress areas can be designed and arranged according to human oral biological data. The utility model does not make special restrictions.

[0039] In an embodiment, the left side of the main body 1 is provided with a plurality of (five in the example shown in the figure) left side occlusal stress areas 11 distributed in order from front to back, the right side of the main body 1 is provided with a plurality of (five in the example shown in the figure) right side occlusal stress areas 12 distributed in order from front to back, and the front side of the main body 1 is provided with a plurality of (six in the example shown in the figure) front side occlusal stress areas 13 distributed in order from left to right, and each of the left side occlusal stress areas 11, each of the right side occlusal stress areas 12 and each of the front side occlusal stress areas 13 is provided with one of the capsule type detection structures. In this way, the stress areas are divided according to human oral biological data to collect information in the corresponding areas as much as possible, thereby improving the accuracy of the measurement data. When in use: the five left side occlusal stress areas 11 from front to back correspond to the partition measurement of the occlusal force of the contact area of the first premolar to the second or third molar on the left side of the human body, the five right side occlusal stress areas 12 from front to back correspond to the partition measurement of the occlusal force of the contact area of the first premolar to the second or third molar on the right side of the human body, and the six front side occlusal stress areas 13 correspond to the partition measurement of the occlusal force of the contact area of the canine tooth on the left side to the canine tooth on the right side of the human body.

[0040] In an embodiment, the chambers 21 of the capsule type detection structures on each of the left side occlusal stress areas 11 and each of the right side occlusal stress areas 12 are spherical or ellipsoidal or columnar and are distributed in parallel and staggered. In this way, considering the size of the occlusal force of the human body and the elasticity of the material of the main body 1, the overall chamber formed by a plurality of the chambers 21 is more evenly dispersed when subjected to external force, avoiding the influence of the position of the teeth biting, and also avoiding the damage of the teeth to the chambers 21 during measurement, thereby improving the stability of the overall chamber.

[0041] In an embodiment, the chambers 21 of the capsule type detection structures on each of the front side occlusal stress areas 13 are columnar and are distributed in parallel with each other. Since the upper and lower teeth of the canine tooth on the left side to the canine tooth on the right side of the human body are staggered when biting, the occlusion of the contact surface of the two sides of the molar is different, and the above-mentioned columnar design makes the front side teeth contact the chambers as much as possible to collect accurate force information, thereby avoiding the influence of the position of the teeth biting.

[0042] In an embodiment, the main body 1 is in the shape of a flat block, and the middle section of each chamber 21 of each capsule detection structure is coincident with the middle section of the main body 1. Here, the middle section refers to the middle section in the thickness direction of the main body 1, and the user bites along the thickness direction of the main body. This design ensures that 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 the same, thereby avoiding inaccurate force information collection due to the different stiffness of the corresponding regions of the main body 1 contacted by the upper and lower teeth.

[0043] 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, thereby facilitating the formation of the chambers 21 and the channels on the main body 1.

[0044] In an embodiment, each chamber 21 and each adjacent chamber 21 are connected to each other through a branch channel 22 formed on the main body 1 in the capsule detection structure. This design facilitates the flow of fluid in the chambers 21 and makes the pressure response more sensitive.

[0045] In an embodiment, the capsule detection structure further includes a main channel formed on the main body 1 and connected to the overall chamber formed by the plurality of chambers 21. The pressure sensor is connected to the main channel, and the main channels of the capsule detection structures are distributed at different positions of the main body along the biting direction of the main body 1. In a specific implementation, the inlet end of the main channel can be connected to one or more chambers 21 and / or one or more branch channels 22, and can be connected to the overall chamber formed by the plurality of chambers 21, thereby detecting the pressure. This design of distributing the main channels at different positions is more reasonable in space utilization, requires a smaller width of the main body, and takes into account the limitations of the oral cavity of the human body, thereby avoiding the influence of the excessive width of the main body on the comfort and accuracy of the human detection results, and reducing the interference between adjacent main channels.

[0046] In an embodiment, along the biting direction of the main body 1, the main channels of the capsule detection structures on the front side biting stress area are distributed in the middle part of the main body 1, the main channels of the capsule detection structures on the part of the left side biting stress area close to the front side biting stress area and the part of the right side biting stress area close to the front side biting stress area are distributed in the middle part of the main body 1, the main channels of the capsule detection structures on the part of the left side biting stress area and the part of the right side biting stress area are distributed in the upper part of the main body 1, and the main channels of the capsule detection structures on the remaining left side biting stress area and the remaining right side biting stress area are distributed in the lower part of the main body 1. This design is more reasonable in space layout.

[0047] For example, as shown in the figure, the middle sections of the main pipes 23d of the capsule type detection structure of the front side occlusal force receiving area 13 and the main pipes 23a of the capsule type detection structure of the left side occlusal force receiving area 11 and the right side occlusal force receiving area 12 arranged in the first from front to back coincide with the middle section of the main body 1; the middle sections of the main pipes 23b of the capsule type detection structure of the left side occlusal force receiving area 11 and the right side occlusal force receiving area 12 arranged in the second and the fourth from front to back are parallel to each other and located at the upper part of the main body 1; the middle sections of the main pipes 23c of the capsule type detection structure of the left side occlusal force receiving area 11 and the right side occlusal force receiving area 12 arranged in the third and the fifth from front to back are parallel to each other and located at the lower part of the main body 1. In this way, the structure is more symmetrical, the distribution of the holes is more reasonable, the detection is more accurate, the width of the main body is more compact, and the thickness is smaller.

[0048] The first position layer is preferably the middle section of the main body 1, and the chambers 21 of the capsule type detection structure are distributed in the first position layer. In this way, the structure is more symmetrical, the distribution of the holes is more reasonable, and the detection is more accurate.

[0049] In an embodiment, the left side occlusal force receiving area 11, the right side occlusal force receiving area 12 and the front side occlusal force receiving area 13 are located at the rear part of the main body 1, and the main pipes of the capsule type detection structure all extend to the front part of the main body 1. In this way, the rear part of the main body 1 is used to stretch into the oral cavity, the front part of the main body 1 is used to hold or connect the support body, and the practicability is better; and the main pipes all extend to the front part of the main body 1, so that the influence of the change of the force receiving area on the measurement is smaller, the force collection of the corresponding force receiving 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.

[0050] In specific implementation, the capsule type detection structure in different force receiving areas is filled with gas, liquid or gas-liquid mixture, and the initial filling pressure can be the same or different, so as to change the bearing capacity of different force receiving areas, so that the bearing capacity of different force receiving areas can be the same or different, so that the evaluation instrument can measure a larger pressure.

[0051] In an embodiment, the main body 1 is detachably installed on the support body. In this way, the main body 1 is convenient to disassemble and clean or replace. In specific implementation, the support body can be a pistol type handle structure or a long handle type handle structure, and the utility model is not particularly limited as long as it is convenient to hold.

[0052] 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 14, the left and right sides of the support body 3 are respectively hinged 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 14 under the elastic force of the spring 33 (the position of the corresponding clamping groove 14 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, improve the stability, and when disassembled, 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 14 to release the main body 1, and then the main body 1 can be removed.

[0053] In the specific implementation, referring to Figure 7 The 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 detection structure is deformed under force, the chamber 21 in the capsule detection structure is deformed under force, 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 force 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. The specific wireless communication methods include but are not limited to Bluetooth transmission, WiFi transmission or infrared transmission, such as sending to a computer. The computer has a related program for processing digital signals, which can process data through the related program and feed back valuable analysis results to the user. The signal processing module can be packaged inside the support body 3.
