Technical Field

[0001] This utility model belongs to the technical field of pressure sensors, specifically relating to an external protective structure for a pressure sensor. Background Technology

[0002] A pressure sensor is a sensor used to measure the pressure of liquids or gases. It converts pressure signals into electrical signals for monitoring and control. Pressure sensors are widely used in industries such as industry, automotive, aerospace, and medical. The external protective structure of a pressure sensor protects it. Existing external protective structures mainly consist of a protective shell, a sound outlet, an LCD screen, control buttons, a fixing ring, a connecting ring, a mounting ring, a protective hose, the sensor body, a data acquisition chip, a processing chip, a main control chip, a buzzer, and transmission lines. However, existing external protective structures have poor heat dissipation during use, and dust can enter the protective shell through the heat dissipation holes, affecting the normal operation of the electronic components inside the protective shell. Therefore, an external protective structure for pressure sensors is essential. Utility Model Content

[0003] The purpose of this invention is to provide an external protective structure for a pressure sensor, in order to solve the problems mentioned in the background art, such as poor heat dissipation of existing external protective structures for pressure sensors during use and the fact that dust can enter the protective shell through the heat dissipation holes and affect the normal operation of the electronic components inside the protective shell.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an external protective structure for a pressure sensor, comprising...

[0005] The protective housing and the mounting groove located on the left wall of the protective housing;

[0006] The protective shell has a retrieval slot on its left wall and located on both sides of the mounting slot, and an insertion hole on its left wall and located at the center of the mounting slot.

[0007] A heat dissipation protection box is installed inside the mounting slot. An air outlet is provided on the left wall of the heat dissipation protection box. An air inlet pipe is connected to the right wall of the heat dissipation protection box, located inside the socket. A battery box is provided at the lower right corner of the right wall of the heat dissipation protection box.

[0008] A rubber sleeve is installed on the outside of the heat dissipation protection box and on the inside of the mounting slot. A placement slot is provided on the outside of the rubber sleeve, and a magnetic plate is installed on the inside of the placement slot.

[0009] The interior of the heat dissipation and protection box contains, from left to right, blades, an output shaft, and a motor body;

[0010] The motor body is connected to the battery box via a power cord, and the protective shell is electrically connected to an external power source.

[0011] The aforementioned heat dissipation protection box not only enhances the dustproof performance of the protective shell but also improves its heat dissipation performance. Furthermore, the combined use of mounting slots, holes, rubber sleeves, magnetic plates, snap-fit ​​connections, plug-ins, and magnetic connections enhances the stability of the heat dissipation protection box during installation and the ease of disassembly.

[0012] The protective shell has a sound outlet at the front and is made of aluminum alloy.

[0013] An LCD screen is provided at the front of the protective housing and below the sound outlet, and a control button is provided at the front of the protective housing and below the LCD screen.

[0014] A retaining ring is installed at the lower end of the protective shell, and a connecting pipe is connected to the lower end of the retaining ring.

[0015] The fixing ring and the connecting pipe are an integral structure, and the fixing ring and the protective shell are fixedly connected by welding.

[0016] An installation ring is installed at the lower outer position of the connecting tube, a protective hose is connected to the lower end of the installation ring, and a sensor body is installed at the lower end of the protective hose.

[0017] The protective housing contains a data acquisition chip, a processing chip, a main control chip, and a buzzer. The sensor body is connected to the data acquisition chip, the data acquisition chip to the processing chip, the processing chip to the main control chip, and the main control chip to the buzzer via transmission lines. The coordinated use of the sensor body, data acquisition chip, processing chip, and main control chip enhances the detection capability of the pressure sensor.

[0018] Compared with the prior art, the present invention provides an external protective structure for a pressure sensor, which has the following advantages:

[0019] This invention improves the external protective structure of a pressure sensor. When using the external protective structure, a magnetic plate is first embedded inside the placement groove, so that the magnetic plate is installed on the outside of the rubber sleeve. Next, the rubber sleeve is glued to the outside of the heat dissipation protective box. Then, the heat dissipation protective box is snapped into the mounting groove, and the air inlet pipe is inserted into the socket. When the heat dissipation protective box enters the mounting groove, the rubber sleeve on the outside of the heat dissipation protective box will press against the inner wall of the mounting groove. Simultaneously, because the protective shell is made of aluminum alloy, the magnetic plate on the outside of the rubber sleeve will attract to the protective shell, thus ensuring the heat dissipation protective box is properly installed. On the left wall of the protective shell, when the internal temperature of the protective shell rises, the motor inside the heat dissipation box draws in hot air from inside the protective shell through the air inlet and then exhausts it through the air outlet, thereby reducing the internal temperature of the protective shell. Because the setting of heat dissipation holes is reduced, dust can be prevented from entering the protective shell through the heat dissipation holes and affecting the electronic components inside the protective shell. Through the setting of the heat dissipation box, not only is the dustproof performance of the protective shell enhanced, but also its heat dissipation performance is enhanced. The combined use of mounting slots, holes, rubber sleeves, magnetic plates, snap-fit, plug-in, and magnetic connections enhances the stability of the heat dissipation box installation and the convenience of disassembly.

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.

[0028] This utility model provides, for example Figure 1-6 The pressure sensor shown has an external protective structure, comprising a protective housing 1 and a mounting groove 13 located on the left wall of the protective housing 1; a retrieval groove 2 is provided on the left wall of the protective housing 1 at the front and rear sides of the mounting groove 13, and an insertion hole 12 is provided on the left wall of the protective housing 1 at the center of the mounting groove 13; a heat dissipation protective box 4 is installed inside the mounting groove 13, an air outlet 3 is provided on the left wall of the heat dissipation protective box 4, an air inlet pipe 23 is connected to the right wall of the heat dissipation protective box 4 inside the insertion hole 12, and a battery box 24 is provided at the lower right corner of the right wall of the heat dissipation protective box 4; the heat dissipation protective box 4 is located outside the mounting groove 13. A rubber sleeve 27 is installed on the inner side of the heat dissipation protective box 4, and a placement groove 26 is provided on the outer side of the rubber sleeve 27. A magnetic plate 25 is installed inside the placement groove 26. The heat dissipation protective box 4 is arranged from left to right as follows: blade 21, output shaft 20 and motor body 22. The motor body 22 is connected to the battery box 24 through a power cable, and the protective shell 1 is electrically connected to an external power source. The heat dissipation protective box 4 not only enhances the dustproof performance of the protective shell 1, but also enhances its heat dissipation performance. The combined use of the mounting groove 13, the insertion hole 12, the rubber sleeve 27, the magnetic plate 25, the snap-fit, the insertion, and the magnetic connection enhances the stability of the heat dissipation protective box 4 during installation and the ease of disassembly.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, to enhance the dustproof and heat dissipation performance of the protective housing 1, when using the outer protective structure of the pressure sensor, the magnetic plate 25 is first embedded inside the placement groove 26, so that the magnetic plate 25 is installed on the outside of the rubber sleeve 27. Then, the rubber sleeve 27 is glued to the outside of the heat dissipation protective box 4. Then, the heat dissipation protective box 4 is snapped into the mounting groove 13 and the air inlet pipe 23 is inserted into the socket 12. When the heat dissipation protective box 4 enters the mounting groove 13, the rubber sleeve 27 on the outside of the heat dissipation protective box 4 will squeeze the inner wall of the mounting groove 13. At the same time, since the protective housing 1 is made of aluminum alloy, the magnetic plate 25 on the outside of the rubber sleeve 27 will be attracted to the protective housing 1, thereby making the heat dissipation protective box... Installed on the left wall of the protective housing 1, when the internal temperature of the protective housing 1 rises, the motor inside the heat dissipation protective box 4 will draw the hot air inside the protective housing 1 through the air inlet pipe 23 and then discharge it through the air outlet 3, thereby reducing the internal temperature of the protective housing 1. Because the setting of heat dissipation holes is reduced, dust can be prevented from entering the protective housing 1 through the heat dissipation holes and affecting the electronic components inside the protective housing 1. Through the setting of the heat dissipation protective box 4, not only is the dustproof performance of the protective housing 1 enhanced, but also the heat dissipation performance of the protective housing 1 is enhanced. The combined use of the mounting slot 13, the socket 12, the rubber sleeve 27, the magnetic plate 25, the snap-fit, the plug-in, and the magnetic connection enhances the stability of the heat dissipation protective box 4 during installation and the convenience of disassembly.

[0030] A sound outlet 11 is provided at the front of the protective housing 1. The protective housing 1 is made of aluminum alloy. An LCD screen 10 is provided at the front of the protective housing 1, below the sound outlet 11. A control button 9 is provided at the front of the protective housing 1, below the LCD screen 10. A fixing ring 14 is installed at the lower end of the protective housing 1. A connecting pipe 8 is connected to the lower end of the fixing ring 14. The fixing ring 14 and the connecting pipe 8 are an integral structure. The fixing ring 14 and the protective housing 1 are fixedly connected by welding. A connecting pipe 8 is installed at the lower outer end of the connecting pipe 8. There is an installation ring 5, and a protective hose 7 is connected to the lower end of the installation ring 5. The sensor body 6 is installed at the lower end of the protective hose 7. Inside the protective shell 1, there are a data acquisition chip 15, a processing chip 19, a main control chip 18, and a buzzer 16. The sensor body 6 is connected to the data acquisition chip 15, the data acquisition chip 15 is connected to the processing chip 19, the processing chip 19 is connected to the main control chip 18, and the main control chip 18 is connected to the buzzer 16 via a transmission line 17. Through the coordinated use of the sensor body 6, the data acquisition chip 15, the processing chip 19, and the main control chip 18, the detection of the pressure sensor is enhanced.

[0031] like Figure 1 , Figure 3 and Figure 4As shown, to enhance the detection of the pressure sensor, when using the outer protective structure of the pressure sensor, the sensor body 6 is first placed in the solution. The pressure of the measured medium acts on the diaphragm of the sensor body 6, causing the diaphragm to produce a micro-displacement proportional to the medium pressure, resulting in a change in the resistance value of the sensor body 6. The electronic circuit detects this change and transmits the data to the acquisition chip 15 through the transmission line 17. The acquisition chip 15 amplifies the data and transmits it to the processing chip 19 through the transmission line 17. The processing chip analyzes the data and transmits it to the main control chip 18 through the transmission line 17. The main control chip 18 saves the data and transmits it to the LCD screen 10 for display. Through the coordinated use of the sensor body 6, the acquisition chip 15, the processing chip 19, and the main control chip 18, the detection of the pressure sensor is enhanced.
