Description

Technical Field

[0001] The present invention relates to the technical field of temperature and humidity transmitters, and in particular to a wall-mounted temperature and humidity transmitter. Background Art

[0002] A temperature and humidity transmitter is a transmitter device equipped with hygroscopic and thermal elements that can be used to measure temperature and humidity. Due to its small size, stable performance, and high accuracy, it is widely used in various fields of life. A temperature and humidity transmitter is a transmitter device that measures temperature and humidity. When the temperature and humidity transmitter is working, it uses an integrated temperature and humidity probe as a temperature measuring element to collect temperature and humidity signals. After voltage stabilization and filtering, operational amplification, nonlinear correction, V / I conversion, constant current, and reverse protection circuit processing, it is converted into a current signal or voltage signal output that is linearly related to temperature and humidity.

[0003] When the temperature and humidity transmitter transmits data, it needs to transmit data through cables. Therefore, the temperature and humidity transmitter needs to connect cables. The connecting cables are usually exposed to the external environment and are easily affected by factors such as wear, pulling, and aging. For example, during installation or use, if the cable is accidentally pulled, the wire inside the cable may break or the insulation layer may be damaged, causing short circuits, open circuits and other faults, affecting the normal operation of the transmitter. After long-term use, the wiring terminals at the connection may oxidize, corrode, and other phenomena, resulting in increased contact resistance, affecting the quality of signal transmission, and the larger contact resistance will significantly increase the heat generated by the current doing work here, resulting in a rapid rise in temperature at the wiring terminal, forming a local hot spot, and may also scorch the nearby insulating materials and plastic shells, burying safety hazards such as short circuits and fires.

[0015] The beneficial effects of the present invention are as follows: 1. During the use of the device, the filter plate can filter the air entering from the outside, reduce the damage to the surface of the terminal by dust and moisture from the outside, reduce the occurrence of corrosion on the surface of the terminal, thereby reducing the influence of the outside air on the terminal and improving the service life of the terminal; when the terminal heats up due to overload, the expansion airbag can be heated and expanded to drive the movable plate to move, so that the movable plate is separated from the exhaust hole, thereby opening the exhaust hole, so that carbon dioxide gas is released to the surface of the terminal, thus completing the cooling effect. And when the expansion airbag moves, the valve opens, and the carbon dioxide gas is quickly blown to the surface of the filter plate through the air blowing hole, and the filter plate is cleaned by reverse blowing to ensure the subsequent filtering effect of the filter plate, increase the air circulation, reduce the accumulation of heat at the connection, improve the heat dissipation effect. At the same time, through the setting of the return spring and the limiting plate, when the cable one is pulled, the limiting plate can be synchronously driven to move inside the placement cavity, so that the wound cable two is released, thereby forming a buffering effect at one end distance. The return spring absorbs the mechanical stress during the external stretching, avoids the loosening of the connection during the pulling process, thus avoiding mechanical damage to the terminal itself or the connected cable, maintaining the mechanical integrity of the cable and the terminal, extending the service life, reducing the replacement frequency, and ensuring the normal transmission of signals.

[0016] 2. When a wiring terminal catches fire due to excessive temperature, as the temperature further rises, one end of the expansion airbag will move to the maximum limit range. At this time, not only the exhaust hole opens, but also the magnetic block will move to one side of the extension cylinder. The repulsive force of magnetic interaction can cause the movable rod to squeeze the block, separating the block from the card slot. At the same time, the elasticity of the buffer spring can drive the block to slide inside the chute, thus completing the separation between the wiring terminal and the conductive sheet, and then completing the power-off. During this process, a large amount of carbon dioxide gas can be released from the exhaust hole, and the movement of the expansion airbag can also slow down the release of the gas, thereby realizing the fire extinguishing treatment of the wiring terminal, avoiding the spread of the fire, and improving the safety of equipment use.

[0023] Docking of the wiring component 6 and the connection component 5: When using the temperature and humidity transmitter body 1, it can be fixed at a set position through the mounting base 7 and the corresponding clamping parts, which facilitates the installation and disassembly of the temperature and humidity transmitter body 1. The temperature and humidity probe 3 is used to detect the temperature and humidity in the relevant environment, and then transmit the signal to the temperature and humidity transmitter body 1. Since the overall temperature and humidity transmitter is a prior art, the specific working process and structure will not be described in detail. In addition, when connecting the wiring terminal 63 and the cable, first, one end of the connection seat 52 can be connected to the wiring seat 61. During the mutual insertion of the two, the limit sliding can be carried out through the clamping block 55 and the sliding groove 62 to ensure the accuracy and stability during the connection process. One end of the clamping block 55 is provided with a chamfer. Through the setting of the chamfer, the extrusion of the clamping block 55 by the sliding groove 62 can be promoted, so that the clamping block 55 drives the limit rod 552 to move and compresses the telescopic spring 551. During this process, the wiring terminal 63 will gradually penetrate into the inside of the docking cylinder 57. When the clamping block 55 moves into the inside of the card slot 66, since the depth of the card slot 66 is greater than the depth of the sliding groove 62, at this time, the clamping block 55 is no longer squeezed, and the clamping block 55 is inserted into the inside of the card slot 66 through the elastic recovery of the telescopic spring 551, thus completing the limit fixation between the connection seat 52 and the wiring seat 61. At the same time, as the connection seat 52 moves, it will drive the docking cylinder 57 to squeeze the filter plate 64 and compress the buffer spring 67. The elastic effect of the buffer spring 67 can ensure the stability after the two are connected; and the inside of the storage box 53 is filled with compressed carbon dioxide gas, which provides convenience for subsequent cooling and fire extinguishing.

[0024] Filtration of the air at the connection by the wiring component 6: The filter plate 64 can filter the air entering the inside of the two from the outside, reduce the damage to the surface of the wiring terminal 63 caused by external dust and moisture, and reduce the occurrence of corrosion on the surface of the wiring terminal 63. Before using the wiring terminal 63, an appropriate amount of vaseline, conductive paste or special terminal protection agent can be applied to the surface to form a protective film on the terminal surface to prevent oxygen and moisture from contacting the metal, thereby reducing the possibility of oxidation and corrosion. The filter plate 64 can be made of activated carbon. Using the adsorption effect of activated carbon, organic volatiles, odors, moisture, etc. in the air can be removed, which can improve the air quality and protect the wiring terminal 63 from corrosion and pollution. Or it can be made of fiber materials, such as glass fiber, which is soft in texture, fine in fiber, can be made into different thicknesses and densities, has a large specific surface area, can adsorb fine particles, and filters dust, smoke, etc. in the air through the gaps between the fibers and the adsorption on the fiber surface, and can filter out particles with a smaller particle size, thereby reducing the impact of external air on the terminal and improving the service life of the terminal.

[0025] Further, the connecting component 5 further includes a docking cylinder 57, the docking cylinder 57 is fixedly connected to the inner wall of the connecting seat 52, a groove 56 is formed at one end of the docking cylinder 57, and a plurality of extension cylinders 572 corresponding to the slot holes 54 are circumferentially and arrayedly distributed at one end of the docking cylinder 57. An activity cavity 573 is formed inside the docking cylinder 57, and a plurality of strip-shaped grooves 574 corresponding to the extension cylinders 572 are formed on the inner wall of the activity cavity 573. A conductive sheet 59 is fixedly connected to the inner wall of the docking cylinder 57 away from the port; an exhaust hole 510 is formed on the inner wall of the activity cavity 573, a blowing hole 571 is formed at one end of the activity cavity 573, a valve 575 is arranged inside the blowing hole 571, and one end of the blowing hole 571 is communicated with the groove 56; the activity cavity 573 is communicated with the storage box 53, and a pressure regulating valve 531 is fixedly connected to the inner wall of the activity cavity 573; the connecting component 5 further includes an expansion airbag 58, the expansion airbag 58 is fixedly connected to one end of the activity cavity 573 away from the blowing hole 571, one end of the expansion airbag 58 is fixedly connected to a movable plate 581, the movable plate 581 is slidably connected with the strip-shaped groove 574, a magnetic block 582 is fixedly connected to one side of the movable plate 581, a strip-shaped hole 583 is formed on the side wall of the movable plate 581, and the width of the strip-shaped hole 583 is greater than the inner diameter of the exhaust hole 510.

[0026] Cooling of the connection component 5 to the wiring terminal 63 and cleaning of the filter plate 64: In the initial state, the movable plate 581 blocks the exhaust hole 510, and both the valve 575 and the pressure regulating valve 531 are in the closed state, and the inside of the movable cavity 573 is filled with compressed carbon dioxide gas. When the wiring terminal 63 generates heat due to overload, the inert gas inside the expansion airbag 58 is heated and expanded through heat transfer, causing one end of it to move. At the same time, the moving end of the expansion airbag 58 drives the movable plate 581 to slide on the inner wall of the strip-shaped groove 574, so as to separate the movable plate 581 from the exhaust hole 510, thereby opening the exhaust hole 510, allowing the carbon dioxide gas to be released onto the surface of the wiring terminal 63, thus completing the cooling effect. After the carbon dioxide vaporizes, it will not leave impurities or water stains. After cooling, it will not corrode the wiring terminal 63, nor is subsequent cumbersome cleaning required, which can maintain the cleanliness and electrical performance of the wiring terminal 63, thereby improving safety while ensuring the cooling effect. Moreover, the small volume of the wiring terminal 63 can effectively achieve the cooling effect. At the same time, a sensor electrically connected to the valve 575 is installed inside the expansion airbag 58. When the expansion airbag 58 moves, the valve 575 opens, and the carbon dioxide gas is quickly blown towards the surface of the filter plate 64 through the air blowing hole 571, and the filter plate 64 is cleaned by reverse air blowing to ensure the subsequent filtering effect of the filter plate 64, increase the air circulation, reduce the heat accumulation at the connection, and improve the heat dissipation effect. The inside of the expansion airbag 58 is also filled with inert gas, such as nitrogen, which expands to drive the expansion of the expansion airbag 58 when heated. When the temperature at the connection drops to normal, the expansion airbag 58 returns to its initial position through the recovery of the inert gas and waits for the next cooling treatment, and the exhaust hole 510 is blocked again by the movable plate 581. In addition, the pressure regulating valve 531 is used to detect the pressure of the carbon dioxide inside the movable cavity 573. When the pressure is less than the set value after releasing a part of the carbon dioxide gas, the pressure regulating valve 531 opens the channel to supplement the gas stored in the storage box 53 into the movable cavity 573 to ensure the progress of each cooling effect, and the gas stored in the storage box 53 can also be supplemented manually at any time, and the replenishment of the gas will not be affected when the expansion airbag 58 expands.

[0027] Power-off processing when the connection component 5 causes a terminal fire: If the wiring terminal 63 catches fire due to excessive temperature, as the temperature further rises, one end of the expansion airbag 58 will move to the maximum limit range. At this time, not only the exhaust hole 510 is opened, but also the magnetic block 582 will move to one side of the extension cylinder 572. The extension cylinder 572 can be made of a diamagnetic material to ensure the magnetic transmission between the magnetic block 582 and the movable rod 65. The polarity of the end of the magnetic block 582 away from the movable plate 581 is the same as the polarity of the end of the movable rod 65 away from the clamping block 55. Therefore, when the magnetic block 582 moves to one side of the end of the movable rod 65, the movable rod 65 can be pushed by the repulsive force of magnetism to squeeze the clamping block 55, causing the clamping block 55 to separate from the card slot 66. At the same time, the elasticity of the buffer spring 67 can drive the clamping block 55 to slide inside the chute 62, so as to complete the separation between the wiring terminal 63 and the conductive sheet 59, thus completing the power-off. And a large amount of carbon dioxide gas can be released from the exhaust hole 510 during this process, and the movement of the expansion airbag 58 can also slow down the release of the gas, so as to realize the fire extinguishing treatment of the wiring terminal 63, avoid the spread of the fire, improve the safety of equipment use, and the connection component 5 can be made of high-temperature resistant materials, which helps to be reused multiple times.

[0028] Embodiment 2, refer to Figure 7 , further; The wire assembly 4 includes a cable one 41, a return spring 42, a limit plate 43 and a cable two 44. The return spring 42, the limit plate 43 and the cable two 44 are all located inside the placement cavity 521. The limit plate 43 is slidably connected to the inner wall of the placement cavity 521. The two ends of the return spring 42 are respectively fixedly connected to the side wall of the limit plate 43 and the inner wall of the storage cylinder 51. One end of the cable two 44 passes through the inner wall of the placement cavity 521 and is fixedly connected to the conductive sheet 59. The other end of the cable two 44 passes through the side wall of the limit plate 43 and is fixedly connected to one end of the cable one 41. The other end of the cable one 41 passes through the side wall of the storage cylinder 51.

[0029] Protection of the wire assembly 4 against cable stretching: During the use of the temperature and humidity transmitter body 1, the connection part between the cable and the transmitter is usually relatively fragile. During installation, disassembly, or daily use, if accidentally pulled, it is easy to cause problems such as internal wire breakage and insulation layer damage of the cable. Therefore, through the setting of the return spring 42 and the limit plate 43, during the process of the cable one 41 being pulled, the limit plate 43 can be synchronously driven to move inside the placement cavity 521, and the return spring 42 is compressed. At the same time, the wound cable two 44 is released, thereby forming a buffering effect for a certain distance. The mechanical stress during external stretching is absorbed by the return spring 42 to avoid loosening at the connection during the pulling process, thereby avoiding mechanical damage to the terminal itself or the connected cable, maintaining the mechanical integrity of the cable and the terminal, and extending the service life, reducing the replacement frequency, and ensuring the normal transmission of signals. In addition, after the external pulling force disappears, the limit plate 43 can be driven to return by the elastic recovery of the return spring 42, and the cable two 44 is re-contracted to ensure the protection effect next time.

[0030] It should be noted that the specific model specifications need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail.

[0031] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
