AI Technical Summary
Existing pressure and temperature combination sensors lack impurity filtering structures at the inlet, making them prone to clogging, and also lack anti-loosening structures, leading to loosening and detachment after prolonged use.
A filter cover is installed at the sensor inlet, and the stability of the sensor is enhanced by a reinforcement assembly, including a sleeve, a moving rod, a clamp, a spring, a slot, and reinforcement components, to ensure impurity filtration and sensor fixation.
This effectively avoids clogging by impurities, extends the lifespan of the sensor, prevents it from loosening and falling off, and ensures the long-term stability and reliability of the sensor.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of sensor technology, specifically a pressure and temperature combined sensor. Background Technology
[0002] The pressure-temperature sensor is an integrated sensor that combines temperature and pressure into a single structure. It can simultaneously measure the pressure and temperature of a medium at the same point, making it suitable for applications where both pressure and temperature must be measured. However, current pressure-temperature combined sensors lack a filtering structure at the inlet to remove impurities from the detected medium. After prolonged use, the bottom of the sensor is prone to blockage, rendering it unusable. Furthermore, the surface lacks a corresponding anti-loosening structure, making the sensor susceptible to loosening and detachment after extended use. Therefore, we propose a pressure-temperature combined sensor to address these issues. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example
[0023] like Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of the present invention discloses a pressure and temperature combined sensor, including a pressure and temperature sensor body 1. A rubber elastic sleeve 13 adapted to the shape of the sensor body 1 is fixed at the insertion port at the top of the pressure and temperature sensor body 1. When the connector is inserted into the top of the pressure and temperature sensor body 1, it can enhance the tightness between the two. In use, the rubber elastic sleeve 13 can be turned outwards. After the connector is inserted, the rubber elastic sleeve 13 can be turned inwards. A connector 2 is fixedly connected to the inlet at the bottom of the pressure and temperature sensor body 1. A guide seat 11 adapted to the moving plate 6 is fixed on the connector 2. The moving plate 6 is limited to the... The guide seat 11 has a limiting slot that guides the movable plate 6 when it moves to its uppermost position, allowing the locking head 7 to accurately engage with the slot 9. A sleeve 3 is fitted over the surface of the connector 2, and two sealing rings 12 are fixed inside the sleeve 3. These sealing rings 12 fit tightly against the connector 2, enhancing the tightness of the fit and preventing impurities from entering the connector 2. A filter cover 4 is fixed to the bottom of the sleeve 3, and a movable rod 5 slides through the outer wall of the sleeve 3. A movable plate 6 is fixed to one end of the movable rod 5, and a locking head 7 is fixed to the other end. A spring 8 is fixed inside the settling tank, and the other end of the spring 8 is fixedly connected to the inner wall of the sleeve 3. The outer surface of the connector 2 has a groove 9 that matches the clamp 7. The clamp 7 is engaged inside the groove 9. A reinforcing component 10 is installed on the outer wall of the pressure and temperature sensor body 1. When using this pressure and temperature combined sensor, after it is screwed onto the mounting part, the reinforcing component 10 can be operated to limit the pressure and temperature sensor body 1 again to prevent it from loosening during later use. Impurities in the medium will be filtered through the filter cover 4 to prevent impurities from clogging the inlet of the pressure and temperature sensor body 1. The filter cover needs to be removed later. 4. When removing for cleaning, pull the movable plate 6 to move the movable rod 5. After the movable rod 5 moves, it will move the clamp 7. At this time, the spring 8 will be in a compressed state, and after the clamp 7 moves, it will disengage from the inside of the slot 9. At this time, the sleeve 3 can be separated from the connector 2, and then the filter cover 4 can be cleaned. When installing, repeat the above operation. Put the sleeve 3 on the surface of the connector 2 and move it up to the maximum extent. Then release the movable plate 6. At this time, under the restoring force of the compressed spring 8, the clamp 7 can be re-inserted into the inside of the slot 9. At this time, the filter cover 4 and the sleeve 3 can be clamped and installed on the connector 2.
[0024] like Figure 1 and Figure 4As shown, in some embodiments, the reinforcement assembly 10 includes a bracket 1001 fixed to the outer wall of the pressure-temperature sensor body 1. Two lead screws 1002 are rotatably connected between the upper and lower inner walls of the bracket 1001 via bearings. Each lead screw 1002 has a movable frame 1003 threaded onto its surface. The bottom ends of the two movable frames 1003 slide through the bracket 1001 and extend below it, where a reinforcement ring 1004 is fixed. An anti-slip rubber ring 1005 is fixed to the bottom of the reinforcement ring 1004. The bracket 1001 is provided with a mechanism for driving the two lead screws 1002. The transmission assembly 1006 rotates synchronously. When in use, after the pressure and temperature sensor body 1 is installed, the two lead screws 1002 can be operated to rotate. After the lead screws 1002 rotate, they will drive the moving frame 1003 to move down. After the moving frame 1003 moves down, it will drive the reinforcing ring 1004 to fit tightly against the surface of the mounting part. With the cooperation of the anti-slip rubber ring 1005, the friction between the reinforcing ring 1004 and the surface of the mounting part can be further enhanced, thereby achieving a further anti-loosening effect on the pressure and temperature sensor body 1 after screw-on installation.
[0025] like Figure 4 As shown, in some embodiments, the transmission assembly 1006 includes a rotating ring 100601 rotatably connected to the bracket 1001 with a rotating groove. A gear ring 100602 is fixed to the top of the rotating ring 100601. Gears 100603 are fixed to the surface of the lead screw 1002, and the gears 100603 are meshed with the gear ring 100602. A hexagonal plate 100604 is fixed to the surface of the gear ring 100602. In use, the gear ring 100602 is rotated, which drives the two gears 100603 to rotate, thereby simultaneously driving the two lead screws 1002 to rotate. The hexagonal plate 100604 facilitates the operation of rotating the gear ring 100602 by the operator using tools.
