[0032] See also Figures 1 to 6 .

[0033] In an optional embodiment of the present invention, a bite force capsule detector includes:

[0034] The main body 1 is made of elastic material and is used for receiving teeth bite;

[0035] The sac-type detection structure is provided with multiple ones distributed in different areas of the main body 1. The sac-type detection structure includes multiple chambers 21 opened in the main body 1 and interconnected, and a pressure sensor for measuring the overall chamber pressure formed by the multiple chambers 21 (for the sake of concise description, it is not shown in the figure, and the pressure sensor can use an existing device that can measure the pressure of the pipeline fluid).

[0036] When the detector of the present invention is used, the main body 1 is inserted into the oral cavity of the person being tested, and then the person being tested bites hard to squeeze the cavity 21 of the capsule-type detection structure in the main body 1. In this way, the pressure value of the overall cavity formed by the cavities 21 will change and be detected by the pressure sensor. The pressure signal is analyzed and then the bite force data can be measured. In the capsule-type detection structure, each individual cavity 21 will affect the pressure of the overall cavity. Therefore, cavities 21 bitten at different positions by different persons being tested can be detected. The present invention has better versatility. In addition, different areas of the main body 1 are respectively provided with capsule-type detection structures. Therefore, the present invention can measure the bite force of teeth in different areas in different partitions.

[0037] The elastic material used in the main body 1 of the present invention may be, for example, a polymer material such as silicone, nylon or polyurethane elastomer (TPU), polyethylene, polystyrene, etc. The chamber 21 may be spherical, ellipsoidal or cylindrical. The chambers 21 of each capsule-type detection structure may be arranged in one or more rows. When the chambers of the left bite force bearing area and the right bite force bearing area are spherical, ellipsoidal or cylindrical, the chambers 21 of each row may be staggered. When the chambers 21 of the front bite force bearing area are cylindrical, the chambers 21 of each row may be parallel. The present invention does not impose any 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 force-bearing areas can also be designed and arranged accordingly according to the human oral biological data. The present invention does not impose any special restrictions.

[0039] In one embodiment, the left side of the main body 1 is provided with a plurality of (five are shown in the figure) left-side occlusal force areas 11 distributed sequentially from front to back, the right side of the main body 1 is provided with a plurality of (five are shown in the figure) right-side occlusal force areas 12 distributed sequentially from front to back, and the front side of the main body 1 is provided with a plurality of (six are shown in the figure) front-side occlusal force areas 13 distributed sequentially from left to right, and each of the left-side occlusal force areas 11, each of the right-side occlusal force areas 12 and each of the front-side occlusal force areas 13 is respectively provided with a capsule-type detection structure. With this design, the force zones are divided according to the biological data of the human oral cavity, and information of the corresponding zones is collected as much as possible, thereby improving the accuracy of the measurement data. When in use: the five left occlusal force zones 11 corresponding to the partitions measure the bite force of the contact area from the first premolar to the second molar or the third molar on the left side of the human body from the front to the back, the five right occlusal force zones 12 corresponding to the partitions measure the bite force of the contact area from the first premolar to the second molar or the third molar on the right side of the human body from the front to the back, and the six front occlusal force zones 13 corresponding to the partitions measure the bite force of the contact area from the left canine to the right canine of the human body.

[0040] In one embodiment, the chambers 21 of the capsule-type detection structure on each of the left occlusal force-bearing area 11 and each of the right occlusal force-bearing area 12 are spherical, ellipsoidal or cylindrical and are distributed in parallel in an alternating manner. This design, taking into account the magnitude of the human bite force and the elasticity of the material of the main body 1, enables the overall chamber formed by the multiple chambers 21 to disperse the force more evenly when subjected to external force, avoiding the influence of the bite position, and also avoiding the teeth from damaging the chamber 21 during measurement, thereby improving the stability of the overall chamber to a certain extent.

[0041] In one embodiment, the chambers 21 of the capsule-type detection structure on each of the front occlusal force-bearing areas 13 are columnar and parallel to each other. Since the upper and lower teeth of the human body are staggered when the left canine to the right canine bite, which is different from the bite in which the contact surfaces of the molars on both sides contact each other, the columnar design allows the front teeth to contact the chamber as much as possible to collect accurate force information, avoiding the influence of the bite position.

[0042] In one embodiment, the main body 1 is in a flat block shape, and the middle section of each chamber 21 of each capsule-type detection structure coincides with the middle section of the main body 1. The middle section here refers to the middle section in the thickness direction of the main body 1. The user bites along the thickness direction of the main body. This design can ensure that the thickness between the surface of the main body 1 contacted by the corresponding teeth of the upper and lower jaws of the human body and the chamber 21 is the same, avoiding inaccurate force information collection caused by different stiffness of the corresponding areas of the upper and lower teeth contacting the main body 1 due to thickness factors.

[0043] In a specific implementation, the main body 1 can be manufactured by molding two halves in a mid-section and then bonding them into a whole, so as to facilitate molding the chamber 21 and the channel on the main body 1 .

[0044] In one embodiment, in the capsule-type detection structure, each chamber 21 is connected to the surrounding adjacent chambers 21 via branch pipes 22 provided on the main body 1. With this design, the fluid in the chamber 21 is easier to flow and the pressure response is more sensitive.

[0045] In one embodiment, the capsule-type detection structure further includes a main pipe opened on the main body 1 and connected to the overall cavity formed by the multiple chambers 21, and the pressure sensor is connected to the main pipe. Along the occlusal direction of the main body 1, the main pipes of each capsule-type detection structure are distributed at different positions of the main body. In a specific implementation, the inlet end of the main pipe can be connected to one or more of the chambers 21 and / or one or more of the branch pipes 22, and can be connected to the overall cavity formed by the multiple chambers 21, so as to detect the pressure. This design of the main pipes being distributed at different positions makes space utilization more reasonable, has a small requirement for the width of the main body, can take into account the limitations of the human oral space, avoids affecting the comfort of human detection and the accuracy of the results due to the excessive width of the main body, and can also reduce interference between adjacent main pipes.

[0046] In one embodiment, along the occlusal direction of the main body 1, the main conduits of the capsule-type detection structure on each of the front occlusal stress areas are distributed in the middle of the main body 1, the main conduits of the capsule-type detection structure on part of the left occlusal stress area close to the front occlusal stress area and part of the right occlusal stress area close to the front occlusal stress area are distributed in the middle of the main body 1, the main conduits of the capsule-type detection structure on part of the left occlusal stress area and part of the right occlusal stress area are distributed in the upper part of the main body 1, and the main conduits of the capsule-type detection structure on the remaining left occlusal stress area and the remaining right occlusal stress area are distributed in the lower part of the main body 1. With this design, the spatial layout is more reasonable.

[0047] For example, as shown in the figure, the main pipe 23d of the capsule-type detection structure of each front side bite force area 13, and the main pipe 23a of the capsule-type detection structure of the first left bite force area 11 and the right bite force area 12 from front to back have their middle sections overlap with the middle section of the main body 1; the middle sections of the main pipe 23b of the capsule-type detection structure of the second and fourth left bite force area 11 and the right bite force area 12 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 pipe 23c of the capsule-type detection structure of the third and fifth left bite force area 11 and the right bite force area 12 from front to back are parallel to each other and located at the lower part of the main body 1. With such a design, the structure is more symmetrical, the channel distribution 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 structures are all distributed in the first position layer. In this way, the structure is more symmetrical, the channel distribution is more reasonable, and the detection is more accurate.

[0049] In one embodiment, each of the left occlusal stress-bearing area 11, each of the right occlusal stress-bearing area 12 and each of the front occlusal stress-bearing area 13 is located at the rear of the main body 1, and the main pipes of each of the capsule-type detection structures extend to the front of the main body 1. With this design, the rear of the main body 1 is used to extend into the oral cavity, and the front of the main body 1 is used to hold or connect the following support body, which is more practical; and the main pipes all extend to the front of the main body 1, which has little effect on the change of the measured stress-bearing area, does not affect the force collection of the corresponding stress-bearing area, and the value is more accurate and reliable, and the pressure sensor can be installed at the outlet end of the main pipe.

[0050] In a specific implementation, gas, liquid or a gas-liquid mixture is filled into the sac-type detection structure in different stress-bearing zones, and the initial filling pressure may be the same or different, thereby changing the bearing capacity of different stress-bearing zones, so that the bearing capacity of different stress-bearing zones may be the same or different, so that the evaluator can measure a larger pressure.

[0051] In one embodiment, a support body is further included, and the main body 1 is detachably mounted on the support body. This design facilitates the disassembly of the main body 1 for cleaning or replacement. In a specific implementation, the support body can be a pistol handle structure or a long handle structure, and the present invention does not impose any particular limitation, as long as it is convenient to hold.

[0052] In one embodiment, a slot 31 is provided on the support body 3, and the main body 1 can be detachably inserted into the slot 31. A card slot 14 is provided on the left and right sides of the main body 1, and buttons 32 are hinged on the left and right sides of the support body 3. A spring 33 is connected between one end of the button 32 and the support body 3, and the other end of the button 32 can be inserted into the corresponding card slot 14 under the elastic force of the spring 33 (a clearance hole for the button 32 to pass through is provided at the position of the corresponding card slot 14 on the support body 3). With this design, after the main body 1 is plugged in, the button can position the main body 1 to improve stability. When disassembly is required, only one end of the button needs to be pressed to pull the other end of the button out of the card slot 14 to release the main body 1, and then the main body 1 can be removed.

[0053] For specific implementation, see Figure 7 , a signal processing module can also be set, which includes a signal conditioning unit, an analog-to-digital conversion unit and a communication unit. When the capsule-type detection structure is deformed by force, the chamber 21 inside it is deformed by force, and the pressure is collected by the pressure sensor and converted into an electrical signal. The corresponding relationship between the known pressure change and the output electrical signal change is obtained by calibration, and 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, and the communication unit is used to obtain the digital signal and send the digital signal through wired or wireless communication. The specific method of wireless communication includes but is not limited to Bluetooth transmission, WiFi transmission or infrared transmission, such as sending to a computer, and there is a related program for processing digital signals in the computer, and the data can be processed through the related program, and the valuable analysis results can be fed back to the user. The signal processing module can be encapsulated inside the support body 3.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
