Description

Technical Field

[0001] This utility model relates to the field of pressure sensors, and in particular to a distributed thin-film pressure sensor. Background Technology

[0002] Pressure sensors are electronic measuring tools used to detect, monitor, read, and display changes in pressure applied to a liquid or gas within a closed volume. They come in many types, including diaphragm sensors, sealed sensors, thin-film sensors, and vacuum sensors, and are widely used.

[0003] In the field of oral healthcare, teeth are an important part of the oral cavity, so the detection of occlusal pressure is extremely important. Thin-film pressure sensors, which are commonly used for occlusal pressure, collect occlusal pressure data through electrode sheets and electrode wires. However, in application, due to the unevenness of teeth, the pressure sensitivity of the electrode wires is limited, which directly affects the accuracy of oral occlusal pressure data. To address this, we propose a distributed thin-film pressure sensor. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a distributed thin-film pressure sensor. By installing an electro-film layer on the upper end of the electrode layer and distributing and arranging the electrode lines, the sensitivity of the electrode lines is expanded by the electro-film layer, making the pressure sensing of the electrode lines more comprehensive. At the same time, the waterproof layer prevents saliva from contacting the electro-film layer when the structure is used in the oral cavity, thus not affecting the detection of oral occlusal force, and the data obtained is more accurate.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A distributed thin-film pressure sensor includes a support mechanism, a reinforcement mechanism installed on the inner sides of the upper and lower ends of the support mechanism, and a body mechanism installed on the inner side of the reinforcement mechanism.

[0007] The main body includes a soft base, an electrode layer fixedly mounted on the upper end of the soft base, an electrode wire fixedly mounted on the upper end of the electrode layer, an exhaust groove formed below the electrode wire at the upper end of the electrode layer, a wire outlet terminal fixedly mounted in the middle of the front end of the electrode layer, an electric film layer at the upper end of the electrode layer, and a waterproof layer fixedly mounted on the upper end of the electric film layer. By installing an electric film layer at the upper end of the electrode layer, the electric film layer expands the sensitivity of the electrode wire, making the electrode wire sense pressure more comprehensively, and thus obtaining more accurate data.

[0008] Furthermore, the support mechanism includes a support frame, a latex pad one is fixedly installed in the middle of the support frame, and a latex pad two is fixedly installed inside the support frame on the upper and lower sides of the latex pad one. A through groove is opened inside the front end of the support frame. The latex pad one makes the support frame as a whole avoid rigid structure, thereby the placement position of the support frame can be adjusted according to the occlusion of the teeth in the mouth, increasing the comfort during oral occlusion data testing.

[0009] Furthermore, the reinforcement mechanism includes a retaining strip with a groove inside and a through hole at the outer end. The retaining strip is used to secure the fit of multiple components of the main body mechanism. During installation, the outer end of the retaining strip is attached to the inner end of the support frame, making it less likely to be touched when the teeth bite the device. The retaining strip also increases the ease of removing the main body mechanism from the support frame.

[0010] Furthermore, the soft base is movably installed inside the support frame, and the number of air vents is several. The soft base maintains its flexibility when in contact with the teeth for bite detection, avoiding discomfort during oral bite data detection. At the same time, the electrode film layer is attached to the upper end of the electrode wire, with a gap between it and the electrode layer. When the component is subjected to force during oral bite detection, the air in the gap between the electrode wire and the electrode film layer can be discharged from the air vents, thereby making the obtained bite data more accurate.

[0011] Furthermore, the outgoing terminal and the through slot are compatible.

[0012] Furthermore, the support frame has a U-shaped structure, and there are two support frames connected by a latex pad.

[0013] Furthermore, a main body mechanism is installed in the middle of the latex pad 2 of the latex pad 1, and the latex pad 2 of the latex pad 1 has the same structure.

[0014] Furthermore, the card strip is movably installed in the middle of the support frame, the outer end of the main body mechanism extends into the interior of the groove and is movably connected, and the through hole box groove is connected.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By installing an electrocoating layer on the upper end of the electrode layer and distributing the electrode wires, the sensitivity of the electrode wires is amplified by the electrocoating layer, making the pressure sensing by the electrode wires more comprehensive. At the same time, the waterproof layer prevents saliva from contacting the electrocoating layer when the structure is used in the oral cavity, thus not affecting the oral bite force detection, and the data obtained is more accurate.

[0017] 2. By connecting the two support frames of the U-shaped structure through latex pad one, the inner support frame and the outer support frame remain movable after connection, which is convenient for intraoral adjustment. At the same time, the U-shaped support frame has a high degree of compatibility with the internal structure of the oral cavity, increasing the fit when using oral occlusion data testing. Then, the main body mechanism is installed at the outer end corresponding to latex pad one, and then latex pad two is installed on top of it. Because the teeth in the oral cavity are not uniform, latex pad one deforms during biting, so that each tooth can contact the main body mechanism, thereby facilitating the data collection of the occlusion of each tooth in the oral cavity.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] Reference Figure 1-5 As shown, the distributed thin-film pressure sensor in a preferred embodiment of the present invention includes a support mechanism 1, a reinforcement mechanism 2 installed on the inner side of the upper and lower ends of the support mechanism 1, and a body mechanism 3 installed on the inner side of the reinforcement mechanism 2.

[0027] The main body 3 includes a soft base 301, an electrode layer 302 fixedly mounted on the upper end of the soft base 301, an electrode wire 303 fixedly mounted on the upper end of the electrode layer 302, an exhaust groove 304 located below the electrode wire 303 on the upper end of the electrode layer 302, a wire outlet terminal 305 fixedly mounted on the middle of the front end of the electrode layer 302, an electrical membrane layer 306 on the upper end of the electrode layer 302, and a waterproof layer 307 fixedly mounted on the upper end of the electrical membrane layer 306. By installing the electrical membrane layer 306 on the upper end of the electrode layer 302 and distributing the electrode wires 303, the electrical membrane layer 306 expands the sensitivity of the electrode wires 303, making the pressure sensing of the electrode wires 303 more comprehensive. At the same time, the waterproof layer 307 prevents saliva from contacting the electrical membrane layer 306 when the structure is used in the oral cavity, thus not affecting the oral bite force detection, and the data obtained is more accurate.

[0028] The support mechanism 1 includes a support frame 101. A latex pad 102 is fixedly installed in the middle of the support frame 101. A second latex pad 103 is fixedly installed inside the support frame 101 on the upper and lower sides of the first latex pad 102. A through groove 104 is opened inside the front end of the support frame 101. The first latex pad 102 makes the support frame 101 avoid a rigid structure. As a result, the position of the support frame 101 can be adjusted according to the occlusion of the teeth in the mouth, increasing the comfort during oral occlusion data testing.

[0029] The reinforcing mechanism 2 includes a retaining strip 201. The retaining strip 201 has a groove 202 inside and a through hole 203 at its outer end. The retaining strip 201 is used to fix the firmness of multiple parts of the main body mechanism 3 after they are attached. During installation, the outer end of the retaining strip 201 is attached to the inner end of the support frame 101 so that it is not easy to touch when the teeth bite the device. The retaining strip 201 also increases the convenience of the main body mechanism 3 to be picked up from the support frame 101.

[0030] The soft base 301 is movably installed inside the support frame 101. There are several venting grooves 304. The soft base 301 maintains its softness when in contact with the teeth for bite detection, avoiding discomfort during oral bite data detection. At the same time, the electrode film layer 306 is attached to the upper end of the electrode wire 303 and maintains a gap with the electrode layer 302. When the component is subjected to force during oral bite detection, the air in the gap between the electrode wire 303 and the electrode film layer 306 can be discharged from the venting grooves 304, thereby making the obtained bite data more accurate.

[0031] The output terminal 305 and the through slot 104 are compatible. The arrangement of the output terminal 305 and the through slot 104 enables the device to have a component that can communicate with external instruments, thereby facilitating the transmission of the detected data.

[0032] The support frame 101 has a U-shaped structure, and there are two support frames 101 connected by a latex pad 102. The U-shaped support frame 101 has a high degree of compatibility with the internal structure of the oral cavity, which increases the fit when using oral occlusion data detection, thus making it more conducive to the collection of accurate data.

[0033] The latex pad 102 and the latex pad 2 103 are equipped with a main body mechanism 3 in the middle. The latex pad 102 and the latex pad 2 103 have the same structure. The latex pad 102 is located at the outer end of the main body mechanism 3. Since the teeth in the mouth are not aligned, the latex pad 102 deforms during biting, so that each tooth can contact the main body mechanism 3, thereby facilitating the collection of data on the occlusion of the teeth in the mouth.

[0034] The clip 201 is movably installed in the middle of the support frame 101. The outer end of the main body mechanism 3 extends into the interior of the groove 202 and is movably connected. The through hole 203 communicates with the groove 202. The through hole 203 is designed to prevent the clip 201 from obstructing the ventilation function of the exhaust groove 304 after it is installed at the outer end of the main body mechanism 3.

[0035] Specific implementation process: The technical content of this utility model is a distributed thin-film pressure sensor. First, two U-shaped support frames 101 are connected by a latex pad 102, so that the inner support frame 101 and the outer support frame 102 remain movable after connection, which is convenient for adjustment within the oral cavity. At the same time, the U-shaped support frame 101 has a high degree of adaptability to the internal structure of the oral cavity, increasing the fit when detecting oral occlusion data. Then, the main body mechanism 3 is installed at the outer end of the latex pad 102. After installation, a second latex pad 103 is installed on top of it. Because the teeth in the oral cavity are not uniform, the latex pad 102 deforms during biting, so that each tooth can contact the main body mechanism 3 at any moment, thereby facilitating the detection of each tooth in the oral cavity. The device collects data on tooth occlusion. Its various components work together. Inside the main body 3, an electric film layer 306 is installed on the upper end of the electrode layer 302, and the electrode wires 303 are distributed and arranged. The electric film layer 306 increases the sensitivity of the electrode wires 303, making the pressure sensing of the electrode wires 303 more comprehensive. The soft base 301 maintains the softness of the occlusion detection when in contact with the teeth, avoiding discomfort during oral occlusion data detection. At the same time, the electric film layer 306 is attached to the upper end of the electrode wires 303 and maintains a gap with the electrode layer 302. When the oral occlusion detection causes the component to be under force, the air in the gap between the electrode wires 303 and the electric film layer 306 can be discharged from the exhaust groove 304, thereby making the obtained occlusion data more accurate.
