Description

Technical Field

[0001] The invention relates to the technical field of temperature and humidity measurement, and in particular to a probe structure of a temperature and humidity transmitter. Background Art

[0002] The temperature and humidity transmitter probe is an important component of the temperature and humidity transmitter, which is used to directly measure and sense the temperature and humidity in the environment. The current structure of the temperature and humidity transmitter probe on the market includes: a probe cover and a probe rod, which are connected by threads and sealed with a waterproof gasket. A plug is arranged inside the probe, and a circuit board with a probe chip is arranged on the plug. On the one hand, the plug is used to achieve the sealing of the inside of the product (the part above the plug), and on the other hand, the plug is used to fix the probe chip and the circuit board. In order to prevent rainwater and other liquids from directly entering the probe cover, a filter sleeve is arranged inside the probe cover through which gas can pass but liquid cannot enter from the outside. The filter sleeve is a thicker filtering system, and the external gas enters the probe cover slowly through the filter sleeve, resulting in a slow product response speed and insufficient accuracy.

[0003] If the filter cover is not used, the probe chip is basically in a state of no protection due to the presence of the air inlet. During storage, transportation and use, rainwater, debris and other substances may easily enter the probe cover and adhere to the probe chip, which may affect the measurement accuracy and even cause damage to the probe chip. On the other hand, the probe rod and the probe cover are sealed only by a single waterproof gasket. This sealing method may be insufficient when facing changes in the external environment (such as temperature). Temperature changes may cause the material properties of the waterproof gasket to change, thereby affecting its sealing performance. Moisture may flow from the waterproof gasket to the connection between the probe rod and the probe cover, thereby causing damage to the inside of the probe.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1, refer to Figure 1-Figure 7A temperature and humidity transmitter probe structure includes a shell 1 and a detection chip 5. The shell 1 is composed of a probe rod 101 and a probe cover 102 connected by threads. The threaded section of the probe cover 102 is provided with a mounting platform 104 and a detection cavity 103 from top to bottom. A plug 4 is provided on the mounting platform 104. The cross section of the plug 4 is convex. When the probe rod 101 and the probe cover 102 are installed, the bottom threaded section of the probe rod 101 abuts against the side wall of the plug 4, so that the plug 4 can be fixed. The plug 4 divides the internal space of the shell 1 into two parts, ensuring that the detection chip 5 can contact with the outside world, and can effectively prevent the external water and water vapor from entering the temperature and humidity transmitter body through the internal cavity of the shell 1. It also includes:

[0038] Adjustable detection component: The adjustable detection component is arranged inside the probe rod 101, and the adjustable detection component is used to switch the working state of the detection chip 5;

[0039] Pressure sealing assembly: The pressure sealing assembly is arranged at the upper end of the probe cover 102, and the pressure sealing assembly is used to automatically seal the connection between the probe rod 101 and the probe cover 102;

[0040] Inductive adjustment component: The inductive adjustment component is arranged below the pressure sealing component, and controls the sealing strength of the pressure sealing component according to the change of the external temperature;

[0041] Gas-liquid separation component: The gas-liquid separation component is arranged at the lower end of the probe cover 102. The gas-liquid separation component separates the gas and liquid entering the detection cavity 103 and also blocks the liquid from entering the detection cavity 103;

[0042] Further, the adjustable detection assembly includes an electric telescopic rod 3 fixedly connected to the inside of the probe rod 101, a push rod 301 is slidably connected to the inside of the electric telescopic rod 3, the outer end of the push rod 301 is threadedly connected to a connecting circuit board 302, a wire is connected to the middle of the connecting circuit board 302, a through hole matching the wire is provided on the mounting portion of the electric telescopic rod 3, a detection chip 5 is fixedly arranged above the bottom end surface of the connecting circuit board 302 and is electrically connected to the connecting circuit board 302, a sealing plug 401 is fixedly connected to the connecting circuit board 302 between the detection chip 5 and the push rod 301, the push rod 301 can be driven to move by the electric telescopic rod 3, and then the connecting circuit board 302 and the detection chip 5 thereon can be driven to move;

[0043] It should be noted that: multiple groups of plug rings 402 are fixedly provided on the outer wall of the sealing plug 401, and the plug 4 is provided with notches matching the sealing plug 401 and through holes matching the connection circuit board 302. The detection chip 5 is arranged in a cylindrical shape, and has the following advantages compared with the square chip: the cylindrical chip can usually make more efficient use of space, especially in circular or curved applications. Due to their shape, the cylindrical chip can better adapt to these specific space requirements, thereby improving the integration of the overall device. The cylindrical chip provides better thermal management performance due to its shape, because they have more surface area to dissipate heat, which is essential for maintaining the stability of the device and extending its life. At the same time, it also helps the sensor to more accurately capture the changes in temperature and humidity in the environment. In particular, the cylindrical chip can better form a contact seal with the through hole than the existing square chip.

[0044] Reference Figure 4 , Figure 5 and Figure 7 , when the detection chip 5 is in the probe rod 101, the bottom end of the connecting circuit board 302 is at least partially embedded in the through hole, and the through hole is closed by the cooperation of the connecting circuit board 302 and the flexible plug 4, so that the detection chip 5 is isolated from the detection cavity 103 below the plug 4. In this way, when the temperature and humidity transmitter is not in use (for example, during storage, transportation, etc.), the detection chip 5 and the connecting circuit board 302 are enclosed in the probe rod 101, and even if a filter sleeve is not provided, they can be effectively protected, and the problem of the detection chip 5 being affected in accuracy or even damaged due to long-term exposure is avoided as much as possible;

[0045] Reference Figure 6 and Fig. 9 , when the detection chip 5 is in the detection cavity 103, the plug 4 is completely embedded in the notch. At this time, the sealing plug 401 arranged on the connecting circuit board 302 closes the notch. The detection chip 5 is located below the plug 4 as a whole and isolated from the cavity above the plug 4. In this way, it is ensured that the detection chip 5 can contact with the external gas for measurement, and at the same time, it is avoided as much as possible that external water vapor enters the cavity above the plug 4. A primary seal is formed between the sealing plug 401 and the notch of the plug 4, and a secondary seal can be formed by multiple plug rings 402 on the side wall of the sealing plug 401, which further improves the sealing performance inside the probe rod 101;

[0046] Example 2, refer to Figure 7-Figure 8 The pressure sealing assembly includes an active cavity 9 provided on one side of the threaded section of the probe cover 102 and a sealing airbag 6 fixedly connected to the top of the probe cover 102, a connecting spring 901 is fixedly connected to the bottom wall of the active cavity 9, a pressure rod 902 is fixedly connected to the end of the connecting spring 901, and an air delivery channel 903 is provided between the bottom side wall of the active cavity 9 and the side wall of the sealing airbag 6;

[0047] It should be noted that: the pressure rod 902 is slidably sealed and connected to the inner cavity of the active cavity 9 to ensure that the gas will not overflow from the active cavity 9 when the pressure rod 902 is squeezed; the sealing airbag 6 when the connecting spring 901 is in the initial state is in an unsaturated state; the sealing airbag 6 is annularly arranged; the outer wall of the sealing airbag 6 and the probe cover 102 are sealed to ensure the internal seal between the probe rod 101 and the probe cover 102; the sealing airbag 6 is made of TPU material; the TPU airbag has good inflation and deflation speeds and can be quickly deployed and supported in a short time, which is particularly important in some occasions requiring rapid response; at the same time, the TPU material has good corrosion resistance and weather resistance and can be used for a long time in harsh environments without failure; when the probe rod 101 is installed on the probe cover 102, as the thread is continuously engaged, the probe rod 101 will continuously press down the pressure rod 902; in this process, the connecting spring 901 will be compressed and at the same time , through the gas delivery channel 903, the gas is squeezed into the sealing airbag 6, causing it to gradually expand and fit tightly to the outside of the probe rod 101, thereby achieving effective sealing between the probe rod 101 and the probe cover 102. This design not only ensures the reliability of the seal, but also improves the adaptability and flexibility of the sealing component. Compared with ordinary sealing gaskets, the benefits of using the movable sealing component (especially the sealing airbag 6 equipped with TPU material) as described in the description are mainly reflected in the following aspects: the sealing airbag 6 can be adaptively adjusted to better adapt to mating surfaces of different sizes or shapes, thereby forming a tighter and more uniform contact on the sealing surface. This adaptive adjustment feature makes the sealing performance more excellent and can effectively prevent leakage. When sealing is required, the pressure sealing component can respond quickly and unfold the sealing airbag 6 to provide support and achieve sealing. This rapid response capability makes the component more suitable for occasions where rapid sealing is required;

[0048] Example 3, refer to Figure 6-Figure 10 The induction adjustment component includes an air storage chamber 7 arranged in the probe cover 102 and an air replenishing chamber 8 arranged above the air storage chamber 7. The upper end side wall of the air storage chamber 7 is connected with a connecting chamber 701 through-connected, and a sliding magnetic plate 702 is slidably connected inside the connecting chamber 701. The upper port of the air replenishing chamber 8 is connected with the sealing airbag 6 through-connected, and an air replenishing magnetic plate 801 is slidably connected in the lower end inner cavity of the air replenishing chamber 8;

[0049] It should be noted that the sum of the volumes of the air storage chamber 7 and the connecting chamber 701 is greater than the sum of the volumes of the sealed airbag 6 and the air replenishing chamber 8 and the movable chamber 9, ensuring that when the external temperature changes, the air pressure change in the air storage chamber 7 is greater than the air pressure change in the air replenishing chamber 8, the movable chamber 9 and the sealed airbag 6. The air replenishing magnetic plate 801 and the sliding magnetic plate 702 are arranged opposite to each other, and the magnetic properties of the opposite surfaces of the air replenishing magnetic plate 801 and the sliding magnetic plate 702 are opposite. The magnetic force between the sliding magnetic plate 702 and the air replenishing magnetic plate 801 is greater than the sum of the friction between the sliding magnetic plate 702 and the inner cavity of the connecting chamber 701 and the friction between the air replenishing magnetic plate 801 and the inner cavity of the air replenishing chamber 8. When the sliding magnetic plate 702 moves, the sliding magnetic plate 702 and the air replenishing magnetic plate 801 are in contact with each other. Driven by the magnetic force between the magnetic plates 801, the air replenishing magnetic plate 801 will also move inside the air replenishing cavity 8, so that the air pressure in the sealed airbag 6 can be controlled according to changes in the external environment, thereby meeting different needs. The connecting cavity 701 and the lower end of the air replenishing cavity 8 are set to be equal in length, the cross-section of the connecting cavity 701 is set in an L-shape, and the cross-section of the air replenishing cavity 8 is set in a double L-shaped splicing shape. The cross-section of the sliding magnetic plate 702 is a right-angled trapezoid, and the length of the lower bottom side of the sliding magnetic plate 702 is less than the length of its upper bottom side, ensuring that when the gas in the air storage cavity 7 expands due to heat, the sliding magnetic plate 702 can be effectively pushed to move (even if the side wall of the sliding magnetic plate 702 is in contact with the left end side wall of the connecting cavity 701, the direction indicated by the left end is as shown in FIG. Figure 8 As shown in the figure, the length of the lower bottom edge of the sliding magnetic plate 702 is greater than the width of the lower port of the connecting cavity 701, thereby preventing the sliding magnetic plate 702 from falling inside the lower port of the connecting cavity 701;

[0050] The induction regulating component can automatically regulate the air pressure in the sealed airbag 6 according to the change of external temperature. In winter or when it rains, the external temperature drops, resulting in a decrease in air pressure, which causes the internal air pressure of the sealed airbag 6 to decrease, causing the sealed airbag 6 to shrink, and the pressure against the probe rod 101 to gradually loosen. At the same time, the air pressure in the air storage chamber 7 and the air replenishing chamber 8 will also decrease. Since the sum of the volumes of the air storage chamber 7 and the connecting chamber 701 is greater than the sum of the volumes of the sealed airbag 6, the air replenishing chamber 8 and the movable chamber 9, it is ensured that when the external temperature changes, the air pressure change in the air storage chamber 7 is greater than the air pressure change in the air replenishing chamber 8, the movable chamber 9 and the sealed airbag 6 At this time, the effect of reducing the pressure inside the air storage chamber 7 is greater than that in the air replenishing chamber 8, forming a pressure difference, so that the air storage chamber 7 attracts the sliding magnetic plate 702 in the connecting chamber 701 to move, and driven by the magnetic force, the air replenishing magnetic plate 801 will also move accordingly, and the moving air replenishing magnetic plate 801 squeezes the gas inside the air replenishing chamber 8 into the sealing airbag 6, and by injecting gas into the shrunken sealing airbag 6, the sealing airbag 6 expands and continues to press against the outer wall of the probe rod 101, so that the sealing effect of the device is greatly improved, and the situation that external moisture enters the inside of the probe rod 101 through the gap between the sealing airbag 6 and the probe rod 101 is avoided;

[0051] When the outside temperature is high, the air pressure inside the air storage chamber 7 becomes high, which will cause the sliding magnetic plate 702 to drive the air replenishing magnetic plate 801 to move in the opposite direction, and then the gas inside the sealed airbag 6 can be extracted, and the sealed airbag 6 relaxes the pressure on the outer wall of the probe rod 101, so that the sealed airbag 6 and the probe rod 101 can be ventilated and dissipated. At the same time, when the sealed airbag 6 is relaxed, the ventilation conditions at the connection are improved, which is conducive to the rapid evaporation of moisture, thereby preventing moisture from causing corrosion or short circuit damage to the equipment. By dissipating heat in time and preventing moisture accumulation, the aging and damage of the probe rod 101 and the sealed airbag 6 caused by high temperature and humid environment can be reduced, thereby extending their service life. This design has an automatic adjustment function, which can automatically adjust the tightness of the sealed airbag 6 according to changes in the outside temperature to achieve a balance between sealing and heat dissipation. This automatic adjustment function can simplify operation and reduce later maintenance costs;

[0052] Embodiment 4, referring to Figure 10-12 The gas-liquid separation component includes a separation chamber 203 and a plurality of flow guide channels 2 arranged in the probe cover 102. A liquid guide platform 204 is arranged at the bottom of the separation chamber 203, and an air guide channel 206 is arranged at the top of the separation chamber 203. A plurality of air inlet channels 205 are arranged through the upper end of the air guide channel 206. A plurality of intercepting channels 201 are arranged on both sides of the flow guide channel 2. The upper ends of the intercepting channels 201 close to the inner side of the probe cover 102 are all connected with the shunt channels 202. Through the design of the separation chamber 203, the gas and liquid flowing out of the shunt channel 202 can be effectively separated. The liquid will flow to the liquid guide platform 204 under the action of gravity, and the gas will rise through the air guide channel 206, so as to achieve the purpose of gas-liquid separation.

[0053] It should be noted that: the liquid guiding platform 204 is set to be concave in the center on all sides, and the lower end surface of the liquid guiding platform 204 is flush with the bottom surface of the probe cover 102. A drainage hole is set at the center of the liquid guiding platform 204. The liquid guiding platform 204 is conducive to the convergence of liquid and is quickly discharged through the drainage hole in the center to avoid the accumulation of liquid in the separation chamber 203. The air guiding channel 206 is set in a truncated cone shape, and the ends of the air inlet channel 205 respectively penetrate the bottom wall of the detection chamber 103 and the side walls of the air guiding channel 206, which allows the gas to be evenly distributed and smoothly pass through the air inlet channel 205 into the detection chamber 103, further improving the efficiency of gas-liquid separation. Multiple guide channels 2 are distributed in a circular shape and equidistantly around the central axis of the probe cover 102, ensuring that the gas and liquid can be evenly distributed during the separation process, avoiding local blockage or accumulation, and the ends of the guide channels 2 respectively penetrate the probe The outer wall of the cover 102 and the bottom wall of the detection chamber 103, the lower end of the diverter channel 202 passes through the side wall of the separation chamber 203, the design of the intercepting channel 201 and the diverter channel 202 can further finely control the gas and liquid, the guide channel 2, the intercepting channel 201 and the diverter channel 202 are all set with a small upper port and a large lower port, the intercepting channel 201 is a Tesla valve-like setting, which can effectively control the flow of the liquid and prevent it from entering the detection chamber 103, the guide channel 2, the intercepting channel 201, and the diverter channel 202 are all inclined, the external fluid will enter through the guide channel 2, a part of it will flow upward along the guide channel 2, and the other part of the water flow will be directed to the intercepting channel 201, and a part of the fluid entering the intercepting channel 201 will return, and the other part will fall into the separation chamber 203 through the diverter channel 202;

[0054] The external fluid first enters through multiple guide channels 2 surrounding the probe cover 102. When the fluid flows in the guide channel 2, due to the design of the channel with a small upper port and a large lower port, and the inclined setting, the liquid part (especially the heavier liquid) will flow to the bottom of the channel due to gravity, while the gas part is relatively easy to rise. Part of the fluid is directed to the intercepting channel 201. The Tesla valve-like design of the intercepting channel 201 allows gas to pass through, but can prevent the liquid (especially the liquid with small particles) from flowing further upward, thereby preventing the liquid from entering the detection cavity 103. A part of the liquid entering the intercepting channel 201 will return to the downstream of the guide channel 2 and converge into the guide channel 2. When this part of the returned liquid meets the fluid that continues to enter, due to the special design of the channel, they will form a vortex. The formation of the vortex further prevents the liquid from rising and enhances the gas-liquid separation effect. The other part It will flow into the separation chamber 203 through the diversion channel 202. In the separation chamber 203, due to the concave design of the liquid guide platform 204 on all sides toward the center, the liquid is further gathered and discharged through the drainage hole in the center, while the gas rises through the gas guide channel 206 and multiple air inlet channels 205 to achieve gas-liquid separation. On the one hand, large water molecules can be discharged to the outside along the channel under the action of gravity and will not accumulate inside, which better assists the product in waterproofing and keeps the detection part (detection chip 5) clean and tidy, extending the service life; on the other hand, compared with the vertical air inlet structure adopted in the prior art, even in windy and rainy weather, without using a filter sleeve, it is difficult for rainwater to enter the detection chamber 103 through the above structure and adhere to the detection chip 5, but the outside gas can directly enter the interior through the above structure, and compared with the prior art entering through the filter sleeve, it has a faster response speed and more accurate measurement results.

[0055] The working principle of the probe structure of this temperature and humidity transmitter: Figure 4 , Figure 5 and Figure 7 , by using the connection circuit board 302 and the flexible plug 4, the through hole on the plug 4 can be closed, so as to isolate the detection chip 5 from the detection cavity 103 below the plug 4. In this way, when the temperature and humidity transmitter is not in use (for example, during storage, transportation, etc.), the detection chip 5 and the connection circuit board 302 are sealed inside the probe rod 101, and can be effectively protected even without a filter sleeve, so as to avoid the problem that the detection chip 5 is affected in accuracy or even damaged due to long-term exposure as much as possible;

[0056] Reference Figure 6 and Fig. 9, the push rod 301 can be driven to move by the electric telescopic rod 3, and then the connecting circuit board 302 and the detection chip 5 thereon can be driven to move. When the detection chip 5 is in the detection cavity 103, the plug 4 is completely embedded in the notch. At this time, the sealing plug 401 arranged on the connecting circuit board 302 closes the notch. The detection chip 5 is located below the plug 4 as a whole and isolated from the cavity above the plug 4. In this way, it is ensured that the detection chip 5 can contact with the external gas for measurement, and at the same time, it is avoided as much as possible that external water vapor enters the cavity above the plug 4. A primary seal is formed between the sealing plug 401 and the notch of the plug 4, and a secondary seal can be formed by multiple plug rings 402 on the side wall of the sealing plug 401, which further improves the sealing performance inside the probe rod 101;

[0057] At the same time, the detection chip 5 is arranged in a cylindrical shape. Compared with the square chip, due to their shape, the cylindrical chip can better adapt to these specific space requirements, thereby improving the integration of the overall device. The cylindrical chip provides better thermal management performance due to its shape. This is because they have more surface area to dissipate heat, which is essential for maintaining the stability and extending the life of the device. At the same time, it also helps the sensor to more accurately capture the temperature and humidity changes in the environment. In particular, the cylindrical chip can better form a contact seal with the through hole of the plug 4 than the existing square chip;

[0058] When the probe rod 101 is installed on the probe cover 102, as the threads are continuously engaged, the probe rod 101 will continuously press down the pressure rod 902. In this process, the connecting spring 901 will be compressed. At the same time, through the gas supply channel 903, the gas is squeezed into the sealing airbag 6, causing it to gradually expand and fit tightly to the outside of the probe rod 101, thereby achieving effective sealing between the probe rod 101 and the probe cover 102. This design not only ensures the reliability of the seal, but also improves the adaptability and flexibility of the sealing component. Compared with ordinary sealing gaskets, the sealing airbag 6 in this design can be adaptively adjusted to better adapt to mating surfaces of different sizes or shapes, thereby forming a tighter and more uniform contact on the sealing surface. This adaptive adjustment feature makes the sealing performance more excellent and can effectively prevent leakage. When sealing is required, the pressure sealing component can respond quickly and deploy the sealing airbag 6 to provide support and achieve sealing. This rapid response capability makes the component more suitable for occasions where rapid sealing is required;

[0059] The induction regulating component can automatically regulate the air pressure in the sealed airbag 6 according to the change of external temperature. In winter or when it rains, the external temperature drops, resulting in a decrease in air pressure, which causes the internal air pressure of the sealed airbag 6 to decrease, causing the sealed airbag 6 to shrink, and the pressure against the probe rod 101 to gradually loosen. At the same time, the air pressure in the air storage chamber 7 and the air replenishing chamber 8 will also decrease. Since the sum of the volumes of the air storage chamber 7 and the connecting chamber 701 is greater than the sum of the volumes of the sealed airbag 6, the air replenishing chamber 8 and the movable chamber 9, it is ensured that when the external temperature changes, the air pressure change in the air storage chamber 7 is greater than the air pressure change in the air replenishing chamber 8, the movable chamber 9 and the sealed airbag 6 At this time, the effect of reducing the pressure inside the air storage chamber 7 is greater than that in the air replenishing chamber 8, forming a pressure difference, so that the air storage chamber 7 attracts the sliding magnetic plate 702 in the connecting chamber 701 to move, and driven by the magnetic force, the air replenishing magnetic plate 801 will also move accordingly, and the moving air replenishing magnetic plate 801 squeezes the gas inside the air replenishing chamber 8 into the sealing airbag 6, and by injecting gas into the shrunken sealing airbag 6, the sealing airbag 6 expands and continues to press against the outer wall of the probe rod 101, so that the sealing effect of the device is greatly improved, and the situation that external moisture enters the inside of the probe rod 101 through the gap between the sealing airbag 6 and the probe rod 101 is avoided;

[0060] When the outside temperature is high, the air pressure inside the air storage chamber 7 becomes high, which will cause the sliding magnetic plate 702 to drive the air replenishing magnetic plate 801 to move in the opposite direction, and then the gas inside the sealed airbag 6 can be extracted, and the sealed airbag 6 relaxes the pressure on the outer wall of the probe rod 101, so that the sealed airbag 6 and the probe rod 101 can be ventilated and dissipated. At the same time, when the sealed airbag 6 is relaxed, the ventilation conditions at the connection are improved, which is conducive to the rapid evaporation of moisture, thereby preventing moisture from causing corrosion or short circuit damage to the equipment. By dissipating heat in time and preventing moisture accumulation, the aging and damage of the probe rod 101 and the sealed airbag 6 caused by high temperature and humid environment can be reduced, thereby extending their service life. This design has an automatic adjustment function, which can automatically adjust the tightness of the sealed airbag 6 according to changes in the outside temperature to achieve a balance between sealing and heat dissipation. This automatic adjustment function can simplify operation and reduce later maintenance costs;

[0061] The external fluid first enters through multiple guide channels 2 surrounding the probe cover 102. When the fluid flows in the guide channel 2, due to the design of the channel with a small upper port and a large lower port, and the inclined setting, the liquid part (especially the heavier liquid) will flow to the bottom of the channel due to gravity, while the gas part is relatively easy to rise. Part of the fluid is directed to the intercepting channel 201. The Tesla valve-like design of the intercepting channel 201 allows gas to pass through, but can prevent the liquid (especially the liquid with small particles) from flowing further upward, thereby preventing the liquid from entering the detection cavity 103. A part of the liquid entering the intercepting channel 201 will return to the downstream of the guide channel 2 and converge into the guide channel 2. When this part of the returned liquid meets the fluid that continues to enter, due to the special design of the channel, they will form a vortex. The formation of the vortex further prevents the liquid from rising and enhances the gas-liquid separation effect. The other part It will flow into the separation chamber 203 through the diversion channel 202. In the separation chamber 203, due to the concave design of the liquid guide platform 204 on all sides toward the center, the liquid is further gathered and discharged through the drainage hole in the center, while the gas rises through the gas guide channel 206 and multiple air inlet channels 205 to achieve gas-liquid separation. On the one hand, large water molecules can be discharged to the outside along the channel under the action of gravity and will not accumulate inside, which better assists the product in waterproofing and keeps the detection part (detection chip 5) clean and tidy, extending the service life; on the other hand, compared with the vertical air inlet structure adopted in the prior art, even in windy and rainy weather, without using a filter sleeve, it is difficult for rainwater to enter the detection chamber 103 through the above structure and adhere to the detection chip 5, but the outside gas can directly enter the interior through the above structure, and compared with the prior art entering through the filter sleeve, it has a faster response speed and more accurate measurement results.
