Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a ring electrode type piezoelectric quartz crystal humidity sensor. Background Art

[0002] Quartz piezoelectric sensors, based on the longitudinal piezoelectric effect of quartz crystals, are primarily used in dynamic weighing systems. They convert external forces into charge signals through quartz elements, which are then converted to voltage signals using an external charge amplifier to determine the weight of a moving vehicle. These sensors are often installed on roads to measure axle loads, providing data support for overweight vehicle enforcement.

[0003] Patent CN119334821B proposes a quartz crystal microbalance humidity sensor, its preparation method and monitoring system. The copper oxide nanofiber surface of the sensor's humidity-sensitive layer has abundant oxygen vacancies, which are conducive to the adsorption of water molecules, thereby effectively changing the mass load on the surface of the quartz crystal microbalance. At the same time, the metal oxide CuO is relatively stable in the air.

[0004] The above solution has the following drawbacks: although water molecules are adsorbed by providing a copper oxide nanofiber surface on the surface of the sensor, once the surface protective structure is destroyed, the interior of the sensor will be damaged, and when the sensor is not in use, the conventional protection capability is poor. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a ring electrode piezoelectric quartz crystal humidity sensor to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. The protective assembly composed of two semicircular frames can be wrapped around the periphery of the sensor when the sensor is not in use, thereby preventing dust from falling on the surface of the sensor. Before packaging and protection, the first wiping rod assembly and the second wiping rod assembly are used to wipe and clean the inner ring, outer ring and upper and lower end surfaces of the ring sensor to clean up the residual moisture. When the sensor is in use, the first half frame and the second half frame are separated and moved to the rear end of the sensor to facilitate the use of the sensor.

[0006] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a ring electrode piezoelectric quartz crystal humidity sensor, including a sensor body, a connecting end fixed at the tail end of the sensor body, and a connecting wire fixed at the connecting end, a protective component is provided on the periphery of the sensor body, and the protective component includes a first half frame and a second half frame, the first half frame and the second half frame are wrapped around both sides of the sensor body, a vertical plate is slidably sleeved on the surface of the connecting end, the first half frame and the second half frame are slidably installed on both sides of the vertical plate, and the top and bottom of the first half frame and the second half frame are rotatably installed with arc plates, a first wiping rod assembly is provided inside the first half frame, and a second wiping rod assembly is provided inside the second half frame, and the first wiping rod assembly and the second wiping rod assembly are in friction contact with the surface of the sensor body.

[0007] Furthermore, the protection component also includes elastic cloth, the elastic cloth is accommodated inside the arc-shaped plate, a magnetic strip is fixed to the outside of the elastic cloth, and protruding plates are slidably inserted at both ends of the magnetic strip.

[0008] Furthermore, annular grooves are provided on the inner walls of the first half frame and the second half frame at positions corresponding to the protruding plates, and the outer ends of the protruding plates slide along the annular grooves.

[0009] Furthermore, the first wiping rod assembly and the second wiping rod assembly include a vertical rod and a horizontal rod, the horizontal rod and the vertical rod of the first wiping rod assembly respectively contact the top and the outer ring surface of the sensor body, and the horizontal rod and the vertical rod of the second wiping rod assembly respectively contact the bottom and the inner ring surface of the sensor body.

[0010] Furthermore, vertical grooves are provided on both sides of the outer wall of the vertical plate, and slide plates are fixed on both sides of the first half frame and the second half frame corresponding to the vertical plates, and the slide plates slide along the inside of the vertical grooves.

[0011] Furthermore, semicircular convex strips are fixed on the inner walls of the first half frame and the second half frame at positions corresponding to the cross bars of the first wiping rod assembly and the second wiping rod assembly, and sliding frames are fixed at positions corresponding to the convex strips of the cross bars of the first wiping rod assembly and the second wiping rod assembly, and the sliding frames are slidably mounted on the convex strips.

[0012] Furthermore, a socket is provided on the surface of the vertical plate, and the connecting wire and the connecting end pass through the socket.

[0013] Furthermore, a rubber ring is fixed on the surface of the connecting end, and the insertion hole is in extrusion contact with the rubber ring.

[0014] Beneficial effects of the utility model:

[0015] 1. After the first half frame and the second half frame are combined, the magnet strip is pulled out, and the extended plate slides along the annular groove. After the magnet strips of the first half frame and the second half frame are connected, the elastic cloth in the arc-shaped plate is unfolded to cover the top of the first half frame and the second half frame, forming a complete wrapping frame to protect the sensor body.

[0016] 2. After the arc-shaped plate is rotated to open the utility model, the first wiping rod assembly and the second wiping rod assembly can be manually pushed to slide along the convex strips through their respective sliding frames. Because after the first half frame and the second half frame are merged, the two semicircular convex strips are merged into a circular ring, allowing the first wiping rod assembly and the second wiping rod assembly to wipe the surface of the sensor body and clean up the remaining moisture.

[0017] 3. According to the present invention, after the first half frame and the second half frame are offset by sliding up and down along the vertical plate, the vertical plate can be separated from the rubber ring by means of external force, and then slide toward the rear end along the connecting end and the connecting line. The first half frame and the second half frame will also move synchronously, thereby moving the protective assembly to the rear end of the sensor body, facilitating the normal use of the sensor body. Through the cooperation of the slide plate and the vertical groove, the first half frame and the second half frame can be offset and slid up and down, and at the same time, the first wiping rod assembly and the second wiping rod assembly can be slid away from the sensor body from the upper end and the lower end respectively, thereby facilitating the backward movement of the protective assembly.

[0018] 4. Compared with the prior art, the present invention has a protective assembly composed of two semicircular frames that can be wrapped around the periphery of the sensor when the sensor is not in use, thereby preventing dust from falling on the surface of the sensor. Before packaging and protection, the first wiping rod assembly and the second wiping rod assembly are used to wipe and clean the inner ring, outer ring and upper and lower end surfaces of the annular sensor to clean any residual moisture. When the sensor is in use, the first half frame and the second half frame are separated and moved to the rear end of the sensor to facilitate the use of the sensor. BRIEF DESCRIPTION OF THE DRAWINGS

The first wiping rod assembly 29 and the second wiping rod assembly 212 are in frictional contact with the surface of the sensor body 1. In this scheme, the structure of the sensor body 1 is composed of an existing piezoelectric quartz crystal humidity sensor. When the sensor body 1 is not in use, the first half frame 23 and the second half frame 24 of the protective assembly 2 wrap and protect the sensor body 1 from both sides, and wipe the surface of the sensor body 1. When the sensor body 1 is in use, the first half frame 23 and the second half frame 24 are separated from each other, so that the protective assembly 2 is moved to the rear end connecting line 12.

[0028] In this embodiment, the protection component 2 also includes an elastic cloth 26. The elastic cloth 26 is accommodated inside the arc-shaped plate 25, and a magnetic strip 27 is fixed to the outside of the elastic cloth 26.

After the magnet strips of the first half frame 23 and the second half frame 24 are connected, the elastic cloth 26 in the arc-shaped plate 25 is unfolded to cover the top of the first half frame 23 and the second half frame 24, forming a complete wrapping frame to protect the sensor body 1.

[0029] In this embodiment, the first wiping rod assembly 29 and the second wiping rod assembly 212 include a vertical rod and a horizontal rod, the horizontal rod and the vertical rod of the first wiping rod assembly 29 are in contact with the top and outer ring surface of the sensor body 1 respectively, and the horizontal rod and the vertical rod of the second wiping rod assembly 212 are in contact with the bottom and inner ring surface of the sensor body 1 respectively, and the inner walls of the first half frame 23 and the second half frame 24 are fixed with semicircular convex strips 211 at positions corresponding to the horizontal rods of the first wiping rod assembly 29 and the second wiping rod assembly 212, and the horizontal rods of the first wiping rod assembly 29 and the second wiping rod assembly 212 are fixed with sliding frames 215 at positions corresponding to the convex strips 211, and the sliding frames 215 are fixed with semicircular convex strips 211 at positions corresponding to the horizontal rods of the first wiping rod assembly 29 and the second wiping rod assembly 212, and the sliding frames 215 are fixed with semicircular convex strips 211 at positions corresponding to the convex strips 21 .... The frame 215 is slidably mounted on the convex strip 211, and the horizontal bar and vertical bar of the first wiping rod assembly 29 are in contact with the top and outer side of the sensor body 1, and the horizontal bar and vertical bar of the second wiping rod assembly 212 are in contact with the bottom and inner side of the sensor body 1. After the arc plate 25 is rotated to open, the first wiping rod assembly 29 and the second wiping rod assembly 212 can be manually pushed to slide along the convex strip 211 through their respective sliding frames 215. Because after the first half frame 23 and the second half frame 24 are merged, the two semicircular convex strips 211 are merged into a ring, for the first wiping rod assembly 29 and the second wiping rod assembly 212 to wipe around the surface of the sensor body 1 to clean up the remaining moisture.

[0030] In this embodiment, vertical grooves 213 are provided on both sides of the outer wall of the vertical plate 21, and slides 214 are fixed on both sides of the first half frame 23 and the second half frame 24 corresponding to the vertical plate 21, and the slides 214 slide along the inside of the vertical groove 213, and a socket 22 is provided on the surface of the vertical plate 21, and the connecting line 12 and the connecting end 11 pass through the socket 22, and a rubber ring 13 is fixed on the surface of the connecting end 11, and the socket 22 is squeezed and contacted with the rubber ring 13, and the position of the rubber ring 13 can be snapped into the socket 22 of the vertical plate 21, and then the first half frame 23 and the second half frame 24 just correspond to the center of the sensor body 1, and the sensor body 1 is wrapped and protected. After the first half frame 23 and the second half frame 24 slide up and down along the vertical plate 21 and are staggered, the vertical plate 21 can be separated from the rubber ring 13 by external force, and then slide to the rear end along the connecting end 11 and the connecting line 12, the first half frame 23 and the second half frame 24 will also move synchronously, thereby moving the protective component 2 to the rear end of the sensor body 1, facilitating the normal use of the sensor body 1.

Then the first half frame 23 and the second half frame 24 are just corresponding to the center of the sensor body 1, and the sensor body 1 is wrapped and protected.

The horizontal rod and the vertical rod of the first wiping rod assembly 29 contact the top and the outer side of the sensor body 1, and the horizontal rod and the vertical rod of the second wiping rod assembly 212 contact the bottom and the inner side of the sensor body 1. After the arc plate 25 is rotated and opened, the first wiping rod assembly 29 and the second wiping rod assembly 212 can be manually pushed to slide along the ridge 211 through their respective sliding frames 215. Because the first half frame 23 and the second half frame 24 are merged, The two semicircular convex strips 211 are merged into a circular ring for the first wiping rod assembly 29 and the second wiping rod assembly 212 to wipe the surface of the sensor body 1 to clean the remaining moisture. After the first half frame 23 and the second half frame 24 are merged, the magnet strip is pulled out, and the extended plate 28 slides along the annular groove 210. After the magnet strips of the first half frame 23 and the second half frame 24 are connected, the elastic cloth 26 in the arc plate 25 is unfolded to cover the top of the first half frame 23 and the second half frame 24, forming a complete wrapping frame to protect the sensor body 1.
