[0002] This disclosure is based on the Chinese application with application number 202311398520.8 and application date October 26, 2023, and claims its priority. The disclosed content of the above-mentioned Chinese application is hereby introduced into this disclosure as a whole. Technical Field

[0003] The present application relates to a sensing device and a storage container. Background Art

[0004] To maintain the proper storage condition for the medium in a storage container, it's necessary to simultaneously measure both the medium's temperature and the air pressure within the container. For example, most battery cell housings are filled with electrolyte. During the battery's charge and discharge processes, the positive and negative active materials react with the electrolyte. Prior to filling, the electrolyte is stored in a tank.

[0005] In order to simultaneously measure the temperature of the medium and the air pressure in the storage container, a temperature sensor and an air pressure sensor are required. In order to save space, an integrated temperature and pressure sensor can be used, but this sensor is difficult to apply to occasions where a small aperture is installed on the storage container.

[0006] Summary of the Invention

[0007] The purpose of this application is to make the sensor device suitable for occasions with smaller installation apertures.

[0008] According to a first aspect of the present application, a sensing device is provided, comprising:

[0009] a housing, wherein an air inlet passage is provided therein, and the air inlet passage has an air inlet;

[0010] a temperature sensor disposed at least partially within the housing and configured to detect temperature; and

[0011] an air pressure sensor, at least partially disposed within the housing, the air pressure sensing portion of the air pressure sensor being in communication with the air intake passage and configured to detect air pressure;

[0012] The air intake passage surrounds the outer periphery of the temperature sensor.

[0013] This embodiment features an integrated temperature and pressure sensor. The intake channel surrounds the periphery of the temperature sensor. Compared to designs where the temperature sensor and intake channel are arranged side by side, this design fully utilizes the space surrounding the temperature sensor to accommodate the intake channel, allowing air to enter and pressure detection by the pressure sensor. The intake channel's location facilitates the installation of the sensor. This design not only makes the sensor installation area more compact but also, given a constant intake volume, reduces the maximum radial dimension of the intake channel, thereby reducing the diameter of the sensor installation area. Even when the diameter of the temperature sensor is increased due to its length to ensure reliable detection, it can easily accommodate smaller apertures, improving the sensor's adaptability to apertures during installation.

[0014] In some embodiments, the temperature sensor is cylindrical and is coaxially disposed with the intake passage.

[0015] This embodiment places the temperature sensor coaxially with the air intake passage, ensuring a more uniform radial width at different circumferential locations. This further reduces the diameter of the sensor mounting area, making it easier to accommodate smaller apertures. Furthermore, the uniform air flow through the air intake passage stabilizes the airflow within the housing and the pressure acting on the air pressure sensing element, improving the accuracy of air pressure detection and the precision of the results.

[0016] In some embodiments, the temperature sensing portion of the temperature sensor extends out of the housing through the air inlet.

[0017] This embodiment facilitates direct contact between the temperature sensing portion and the liquid medium when the liquid medium is stored in the container body, thereby more accurately detecting the temperature of the liquid medium.

[0018] In some embodiments, the length section of the housing close to the air inlet is cylindrical and has an external thread, which forms a mounting interface for the sensor device.

[0019] This embodiment utilizes external threads on the housing as mounting interfaces, resulting in a simple structure, ease of machining, and convenient assembly and disassembly. This also facilitates fine-tuning of the sensor's mounting height after installation, allowing for adjustments to the temperature sensing portion's height based on testing requirements. Furthermore, positioning the external threads near the air inlet on the housing helps avoid protruding structures on the container's mounting surface after installation.

[0020] In some embodiments, the sensing device further includes a supporting structure, wherein the supporting structure is abutted between the housing and the temperature sensor.

[0021] This embodiment can provide auxiliary support for the temperature sensor by setting a support structure, increase the connection strength between the temperature sensor and the shell, prevent the cantilever length section of the temperature sensor from shaking, ensure the reliability of the temperature sensor, and improve detection accuracy.

[0022] In some embodiments, the support structure includes a plurality of support members, which are spaced apart along the circumference of the temperature sensor, and at least a portion of the air inlet channel is formed between adjacent support members.

[0023] This embodiment arranges a plurality of support members at circumferential intervals on the temperature sensor, and forms at least a portion of the air intake channel between adjacent support members. This can not only provide stable and uniform auxiliary support for the temperature sensor, but also make full use of the peripheral space of the temperature sensor to form an air intake channel, so that the gas can be transmitted to the pressure sensor to realize pressure detection.

[0024] In some embodiments, at least two support structures are provided, and the at least two support structures are spaced apart along the extension direction of the air inlet passage.

[0025] This embodiment provides multi-point support in the length direction of the temperature sensor by arranging at least two support structures at intervals in the extension direction of the air intake passage, which can further improve the installation stability of the temperature sensor, thereby improving the structural reliability of the entire sensing device and the accuracy of the detection results.

[0026] In some embodiments, the support structure is located in a region of the air inlet passage close to the air inlet port.

[0027] This embodiment arranges the support structure in the area of ​​the air inlet passage close to the air inlet, which can increase the support span of the temperature sensor. In particular, for the structure in which the temperature sensing part extends out of the shell, the length of the cantilever end of the temperature sensor can be further reduced, thereby improving the support stability of the temperature sensor.

[0028] In some embodiments, the shell includes a first part, which is used to form an air inlet channel. The first part includes a first section and a second section. The first section and the second section are split structures. The second section forms an air inlet, and the first section is connected to an end of the second section away from the air inlet. The support structure is arranged in the second section.

[0029] This embodiment takes into account that the first part is a slender cylindrical structure, designs the first part into a segmented structure, and arranges the supporting structure in the second segment. Since the second segment is shorter, especially for the case of setting up multiple supporting structures, the supporting structure can be conveniently fixed in the second segment, reducing the process difficulty and improving the positioning accuracy of the supporting structure.

[0030] In some embodiments, the shell also includes a first part and a second part, the first part is used to form an air intake channel, the second part is connected to the side of the first part away from the air intake port, a fixing seat is provided in the second part, and a first through hole and a mounting groove are provided side by side on the fixing seat, the temperature sensor passes through the first through hole and extends in the air intake channel, the air pressure sensor is provided in the mounting groove, and the mounting groove is connected to the air intake channel.

[0031] This embodiment can conveniently realize the installation and fixation of the temperature sensor and the air pressure sensor, and the assembly process is relatively simple. The installation groove is connected with the air intake channel, so that the intake air can smoothly reach the air pressure sensing part of the air pressure sensor to realize air pressure detection.

[0032] In some embodiments, the mounting groove is opened on the surface of the fixing seat away from the first part, a second through hole is provided on the bottom surface of the mounting groove, and the end surfaces connecting the fixing seat, the second part and the first part are spaced apart to form an air guide channel, and the mounting groove is connected to the air intake channel through the second through hole and the air guide channel.

[0033] By providing the second through hole and the air guide channel, this embodiment allows the gas to enter the housing through the air inlet channel and then pass through the air guide channel and the second through hole in sequence to smoothly reach the air pressure sensing portion, thereby improving the accuracy of air pressure detection.

[0034] In some embodiments, the sensing device further includes a sealing member disposed between the air pressure sensor and the mounting groove.

[0035] This embodiment can achieve sealing of the air pressure sensor by providing a seal, prevent gas leakage from the gap between the air pressure sensor and the mounting groove, and improve the accuracy of air pressure detection; and when the stored medium is gas or volatile liquid, it can prevent the medium from escaping.

[0036] In some embodiments, the temperature sensor is welded to the first through hole at least at its outer end in the entire circumference; and / or the air pressure sensor is welded to the mounting groove at least at its outer end in the entire circumference.

[0037] This embodiment welds the outer ends of the temperature or pressure sensor, facilitating the welding process and reducing the complexity of the process. Furthermore, by welding around the entire circumference of the temperature or pressure sensor, the weld fills the installation gap, preventing gas leakage and providing a seal. Combining full-circumference welding with a sealant achieves a double seal, improving sealing effectiveness and reliability.

[0038] In some embodiments, the sensing device also includes a circuit board, which is arranged on a side of the temperature sensor and the air pressure sensor away from the air intake passage; the air pressure sensor is located on the side of the temperature sensor, and the first electrical lead of the temperature sensor and the second electrical lead of the air pressure sensor are both led out toward one end close to the circuit board and are electrically connected to the circuit board.

[0039] This embodiment places the circuit board on the side of the temperature sensor and pressure sensor away from the air intake passage. This prevents high humidity from reaching the circuit board, the first and second electrical leads, and potentially affecting their reliability, preventing detection failure. Furthermore, in the presence of corrosive media, this prevents gas from reaching the circuit board, the first and second electrical leads, and potentially causing corrosion, thereby extending the service life of the sensor device. Furthermore, this structure facilitates installation of the circuit board from the housing, away from the opening of the air intake passage, and facilitates electrical connection between the first and second electrical leads and the circuit board.

[0040] In some embodiments, the temperature sensor and the air pressure sensor are flush with one end of the circuit board.

[0041] This embodiment allows the temperature sensor and the air pressure sensor to be flush with one end close to the circuit board, so that the first electrical lead-out portion and the second electrical lead-out portion can extend to the same length when connected to the circuit board, and also facilitates electrical connection with the circuit board; moreover, when the outer end surfaces of the temperature sensor and the air pressure sensor extend beyond the mounting surface, the temperature sensor and the air pressure sensor can jointly provide support for the circuit board, thereby improving the installation stability of the circuit board.

[0042] In some embodiments, the temperature sensor and the air pressure sensor both have metal packages.

[0043] This embodiment can protect the internal structure by metal packaging of the sensor, improve the corrosion resistance, and increase the working reliability and service life of the sensor.

[0044] According to a second aspect of the present application, there is provided a storage container, comprising:

[0045] a container body configured to store a medium; and

[0046] The sensor device in the above embodiment is installed on the container body.

[0047] Because this integrated temperature and pressure sensor surrounds the air inlet channel around the perimeter of the temperature sensor, the diameter of the sensor's mounting area can be reduced. Therefore, even when the mounting aperture on the container body is small, it can easily meet installation requirements and measure the temperature and pressure of the medium stored within the container body.

[0048] In some embodiments, a third through hole is provided on the container body, and an end of the shell close to the temperature sensor is installed in the third through hole.

[0049] In this embodiment, the mounting interface of the sensing device is arranged at one end of the shell close to the temperature sensor. In this way, after installation, there is still a spacing distance between the mounting surface of the container body and the second part with a larger cross-sectional area. When there are structures such as protrusions or slopes on the mounting surface, they can also be avoided, thereby improving the adaptability of the sensing device to mounting surfaces of different shapes.

[0050] In some embodiments, the third through hole is a threaded hole, and an end of the shell close to the air inlet is provided with an external thread that matches the threaded hole.

[0051] This embodiment utilizes external threads on the housing as mounting interfaces, resulting in a simple structure, ease of machining, and convenient assembly and disassembly. This also facilitates fine-tuning of the sensor's mounting height after installation, allowing for adjustments to the temperature sensing portion's height based on testing requirements. Furthermore, positioning the external threads near the air inlet on the housing helps avoid protruding structures on the container's mounting surface after installation.

[0066] Current battery cells usually include a shell and an electrode assembly housed in the shell, and the shell is filled with an electrolyte. The electrode assembly is mainly formed by stacking or winding a first electrode sheet and a second electrode sheet with opposite polarities, and an insulating member, such as a diaphragm, is usually provided between the first electrode sheet and the second electrode sheet. The portions of the first electrode sheet and the second electrode sheet coated with active material constitute the main body of the electrode assembly, and the portions of the first electrode sheet and the second electrode sheet not coated with active material each constitute the first electrode tab and the second electrode tab. In a battery cell, the first electrode sheet can be a positive electrode sheet, including a positive electrode current collector and a positive electrode active material layer provided on both sides of the positive electrode current collector. The positive electrode current collector can be a metal foil or a composite current collector. For example, as the metal foil, aluminum or stainless steel with a silver surface treatment, stainless steel, copper, aluminum, nickel, carbon electrode, carbon, nickel or titanium, etc. can be used. The composite current collector can include a polymer material base layer and a metal layer. The composite current collector can be formed by forming a metal material (aluminum, aluminum alloy, nickel, nickel alloy, titanium, titanium alloy, silver and silver alloy, etc.) on a polymer material substrate (such as a substrate made of polypropylene, polyethylene terephthalate, polybutylene terephthalate, polystyrene, polyethylene, etc.). The positive electrode active material layer may include at least one of the following materials: lithium-containing phosphate, lithium transition metal oxide, and their respective modified compounds. However, the present application is not limited to these materials, and other traditional materials that can be used as battery positive electrode active materials may also be used. These positive electrode active materials may be used alone or in combination of two or more. The second electrode sheet may be a negative electrode sheet, including a negative electrode current collector and a negative electrode active material layer provided on both sides of the negative electrode current collector. The negative electrode current collector may be a metal foil or a composite current collector. For example, as the metal foil, aluminum or stainless steel with a silver surface treatment, stainless steel, copper, aluminum, nickel, carbon electrode, carbon, nickel or titanium, etc. may be used. The composite current collector may include a polymer material base layer and a metal layer. The composite current collector can be formed by forming a metal material (copper, copper alloy, nickel, nickel alloy, titanium, titanium alloy, silver and silver alloy, etc.) on a polymer material substrate (such as a substrate of polypropylene, polyethylene terephthalate, polybutylene terephthalate, polystyrene, polyethylene, etc.). The negative electrode active material layer can adopt the negative electrode active material for batteries known in the art. As an example, the negative electrode active material may include at least one of the following materials: artificial graphite, natural graphite, soft carbon, hard carbon, silicon-based material, tin-based material and lithium titanate, etc. Optionally, the first pole piece can also be a negative pole piece, and the corresponding second pole piece is a positive pole piece. During the charge and discharge process of the battery cell, the positive electrode active material and the negative electrode active material react with the electrolyte, and the tabs connect the electrode terminals to form a current loop.

[0067] Before filling the electrolyte, the electrolyte is stored in a tank. Related technologies use integrated temperature and pressure sensors. This type of sensor is difficult to install in small apertures because the air inlet and temperature sensor are structurally arranged side by side and separated from each other, resulting in a large outer diameter at the installation site. Furthermore, to ensure the reliability of the temperature sensor probe, the diameter of the temperature sensor needs to take the length factor into account: the longer the length, the larger the diameter. Therefore, in cases with small installation apertures, for example, less than 10mm, and a temperature measurement depth greater than 0.5m, current integrated temperature and pressure sensors have difficulty meeting installation requirements.

[0068] In order to solve the above problems, the present application provides a sensing device, which includes: a shell, in which an air intake channel is provided, and the air intake channel has an air inlet; a temperature sensor, at least partially provided in the shell, and configured to detect temperature; and an air pressure sensor, at least partially provided in the shell, the air pressure sensing part of the air pressure sensor is connected to the air intake channel, and is configured to detect air pressure; wherein the air intake channel surrounds the outer periphery of the temperature sensor.

[0069] In this sensing device, the air intake passage surrounds the periphery of the temperature sensor, fully utilizing the space around the temperature sensor to accommodate air intake, allowing the pressure sensor to detect air pressure. This structure not only makes the sensor mounting area more compact but also reduces the maximum radial dimension of the air intake passage for a given intake volume. This reduces the diameter of the sensor mounting area, accommodating smaller apertures and improving the sensor's adaptability to apertures.

[0070] 1 is a schematic structural diagram of some embodiments of a storage container. The storage container 100 includes a container body 20 and a sensor device 10. The container body 20 is configured to store a medium, and the sensor device 10 is installed in the container body 20.

[0071] The container body 20 can be a rectangular parallelepiped, cylindrical, or other shape. The medium within the container body 20 can be a liquid or a gas. For example, the liquid can be the electrolyte used to fill battery cells. The sensing device 10 can be mounted on the top wall or side wall of the container body 20. As shown in Figure 2, the sensing device includes a temperature sensor 14 and an air pressure sensor 15. The temperature sensor 14 is used to detect the temperature of the medium, and the air pressure sensor 15 is used to detect the air pressure within the container body 20. If the stored medium is a gas, the air pressure is the medium pressure. If the stored medium is a liquid, the air pressure is the air pressure in the space above the liquid level within the container body 20.

[0072] This type of sensing device 10 can be used in scenarios where both temperature and air pressure need to be detected simultaneously. The following embodiments are mainly described using the electrolyte stored in the container body 20 as an example, that is, the temperature of the electrolyte in the storage tank serving as the container body 20 is detected, and the gas pressure above the liquid surface in the storage tank is detected, but it is not limited to this. The sensing device 10 can be used to detect the temperature and air pressure parameters of any medium stored in any container body 20.

[0073] Figure 2 is a schematic diagram of the structure of some embodiments of a sensing device. The sensing device includes: a housing 10', within which is disposed an air inlet passage 13 having an air inlet port 131; a temperature sensor 14, at least partially disposed within housing 10' and configured to detect temperature; and an air pressure sensor 15, at least partially disposed within housing 10', with an air pressure sensing portion 151 of pressure sensor 15 communicating with air inlet passage 13 and configured to detect air pressure. The air inlet passage 13 surrounds the periphery of the temperature sensor 14.

[0074] The shell 10 ′ can be made of metal material. The medium stored in the container body 20 is corrosive, such as electrolyte, etc., and the shell 10 ′ can be made of corrosion-resistant material.

[0075] The gas in the container body 20 can enter the air inlet channel 13 through the air inlet 131. The temperature sensor 14 can detect the temperature of the medium in the container body 20 through the temperature sensing portion 141. The temperature sensing portion 141 can be in direct contact with the medium or in contact with the medium through gas. For example, the temperature sensing portion 141 can be a thermocouple or a resistance temperature sensor. The resistance temperature sensor can be a platinum resistance temperature sensor, etc., but the type of the temperature sensor 14 is not limited to this.

[0076] The pressure sensing portion 151 of the air pressure sensor 15 is connected to the air inlet passage 13. Gas within the container body 20 passes through the air inlet passage 13 and reaches the pressure sensing portion 151, causing deformation of the pressure sensing portion 151. This deformation is then transmitted to the chip within the pressure sensor 15 to detect the air pressure. For example, the pressure sensor 15 may be an oil-filled core pressure sensor, with a diaphragm at the end of the pressure sensor 15 serving as the pressure sensing portion 151. The pressure sensor 15 is filled with silicone oil. The gas deforms the diaphragm, transmitting pressure through the oil, causing the chip within the pressure sensor 15 to respond to the air pressure. However, the pressure sensor 15 is not limited to this type of sensor.

[0077] The air intake passage 13 surrounds the outer circumference of the temperature sensor 14. The air intake passage 13 surrounds the temperature sensor 14 in part or all of the circumference of the temperature sensor 14. The temperature sensor 14 directly detects the temperature through the temperature sensing portion 141, rather than detecting the temperature through the temperature sensing portion 141 of the temperature sensor 14 after the gas enters the shell 10' through the air intake passage 13.

[0078] This embodiment is directed to an integrated temperature and pressure sensing device. The air intake passage 13 surrounds the periphery of the temperature sensor 14. Compared to a structure in which the temperature sensor and the air intake passage are arranged side by side, the air intake passage 13 can fully utilize the space around the temperature sensor 14 to achieve air intake, so that the air pressure sensor 15 can detect air pressure. The location of the air intake passage 13 is used to install the sensing device 10. This structure not only makes the structure of the installation portion of the sensing device 10 more compact, but also reduces the maximum radial dimension of the air intake passage 13 when the air intake volume is constant, thereby reducing the diameter of the installation portion of the sensing device 10. Even if the length of the temperature sensor 14 is increased to ensure the detection reliability of the temperature sensor 14, it is easier to meet the installation requirements of a smaller aperture, thereby improving the adaptability of the sensing device 10 to the aperture when installing.

[0079] In some embodiments, the temperature sensor 14 is cylindrical and is coaxially disposed with the intake passage 13 .

[0080] Among them, the temperature sensor 14 can be cylindrical, the intake channel 13 is located outside the temperature sensor 14, the cross-section of the intake channel 13 can be a ring that is continuous along the circumference, or the ring can be divided into multiple parts along the circumference; the intake channel 13 can extend along part or the entire circumference of the temperature sensor 14.

[0081] This embodiment places temperature sensor 14 coaxially with intake passage 13, making the radial width of intake passage 13 more uniform at different circumferential locations. This further reduces the diameter of the mounting portion of sensor device 10, making it easier to accommodate smaller apertures. Furthermore, the uniform air flow through intake passage 13 stabilizes the airflow within housing 10' and the pressure acting on air pressure sensing portion 151, thereby improving the accuracy of air pressure detection and the precision of the air pressure detection results.

[0082] In some embodiments, the temperature sensing portion 141 of the temperature sensor 14 extends out of the housing 10 ′ through the air inlet 131 .

[0083] The temperature sensor 14 penetrates through the end of the housing 10 ′ away from the air inlet 131 , and the temperature sensing portion 141 extends out of the housing 10 ′ from the air inlet 131 for a distance after passing through the air inlet passage 13 .

[0084] For example, when a liquid medium is stored in the container body 20, the extended length of the temperature sensing part 141 may not be less than the distance between the mounting interface of the sensing device 10 and the liquid surface of the medium. The distance is constructed so that the temperature sensing part 141 is in direct contact with the liquid medium, including the temperature sensing part 141 at the end just contacting the liquid surface or extending into the medium, and there is still a gap between the air inlet 131 and the liquid surface of the medium. This can not only accurately detect the temperature of the liquid medium, but also allow the gas in the container body 20 to reach the air pressure sensor 15 through the air inlet channel 13 to realize air pressure detection.

[0085] This embodiment facilitates direct contact between the temperature sensing portion 141 and the liquid medium when the liquid medium is stored in the container body 20 , thereby more accurately detecting the temperature of the liquid medium.

[0086] In some embodiments, the length section of the housing 10 ′ near the air inlet 131 is cylindrical and has an external thread 113 . The external thread 113 forms a mounting interface for the sensor device 10 .

[0087] As shown in FIG1 , the container body 20 of the storage container 100 may be provided with a third through hole 201, which is a threaded hole. The external thread 113 on the housing 10′ engages with the third through hole 201 to enable installation of the sensor device 10. Alternatively, the mounting interface on the housing 10′ may be a snap fastener or the like.

[0088] This embodiment provides external threads 113 on the housing 10' as a mounting interface. This provides a simple structure, ease of machining, and convenient assembly and disassembly. It also facilitates fine-tuning of the sensor device 10's mounting height after installation, adjusting the height of the temperature sensing portion 141 based on detection requirements. Furthermore, positioning the external threads 113 near the air inlet 131 on the housing 10' helps avoid protruding structures on the mounting surface of the container body 20 after installation.

[0089] In some embodiments, as shown in FIG. 2 , the sensing device further includes a support structure 16 , which is abutted between the housing 10 ′ and the temperature sensor 14 .

[0090] The support structure 16 abuts the inner surface of the housing 10' and the outer surface of the temperature sensor 14. The support structure 16 can be a separate component connected to the housing 10', or it can be integrally formed with the housing 10'. Because the temperature sensor 14 is a slender structure, if it is fixed only at the tail end, the cantilevered length is prone to shaking, affecting installation stability.

[0091] This embodiment provides auxiliary support for the temperature sensor 14 by setting the support structure 16, which can increase the connection strength between the temperature sensor 14 and the housing 10', prevent the cantilever length section of the temperature sensor 14 from shaking, ensure the reliability of the temperature sensor 14, and improve the detection accuracy.

[0092] In some embodiments, as shown in FIG. 3 , the support structure 16 includes a plurality of support members 161 . The plurality of support members 161 are spaced apart along the circumference of the temperature sensor 14 , and at least a portion of the air intake passage 13 is formed between adjacent support members 161 .

[0093] Alternatively, the plurality of support members 161 may be radially distributed, extending radially from the temperature sensor 14; alternatively, the support members 161 may extend at an angle to the radial direction of the temperature sensor 14. For example, the support members 161 extending along a straight line or a curve are both within the scope of protection of this application, as long as a cavity is formed between adjacent support members 161 to facilitate air intake. Alternatively, the support members 161 may be in the form of an elongated strip or a thin plate extending axially from the temperature sensor 14.

[0094] For example, the first end of the support member 161 can be directly connected to the inner wall of the housing 10', for example, by welding the first end of the support member 161 to the inner wall of the housing 10'; or the first ends of multiple support members 161 can be connected via a first annular portion, which can then be connected to the inner wall of the housing 10' by welding or other means. The second end of the support member 161 can be a free end. After the temperature sensor 14 passes through the multiple support members 161, the outer wall of the temperature sensor 14 can be directly supported by the second ends of the multiple support members 161; or the second ends of the multiple support members 161 can be connected via a second annular portion, which can then support the temperature sensor 14. This structure makes it easier to install the temperature sensor 14 and provides better positioning.

[0095] For example, in FIG3 , four support members 161 are provided. In addition, two, three or more support members may be provided as needed.

[0096] This embodiment provides a plurality of support members 161 at circumferential intervals on the temperature sensor 14, and forms at least a portion of the air intake channel 13 between adjacent support members 161. This can not only provide stable and uniform auxiliary support for the temperature sensor 14, but also make full use of the peripheral space of the temperature sensor 14 to form the air intake channel 13, so that the gas can be transmitted to the pressure sensor 15 to realize pressure detection.

[0097] In some embodiments, as shown in FIG. 2 , at least two support structures 16 are provided, and the at least two support structures 16 are spaced apart along the extending direction of the air intake passage 13 .

[0098] This embodiment provides multi-point support in the length direction of the temperature sensor 14 by arranging at least two support structures 16 at intervals in the extension direction of the air intake passage 13, which can further improve the installation stability of the temperature sensor 14, thereby improving the structural reliability of the entire sensing device 10 and the accuracy of the detection results.

[0099] In some embodiments, the support structure 16 is located in a region of the air inlet passage 13 close to the air inlet port 131 .

[0100] In order to facilitate the fixation of the temperature sensor 14, it is generally fixed at the tail end of the temperature sensor 14, and the support structure 16 is set in the area of ​​the intake channel 13 close to the air inlet 131, and the head end of the temperature sensing part 141 of the temperature sensor 14 can be set to fix it.

[0101] In this embodiment, the support structure 16 is arranged in the area of ​​the air inlet passage 13 near the air inlet 131, which can increase the support span of the temperature sensor 14. In particular, for the structure in which the temperature sensing portion 141 extends out of the shell 10', the length of the cantilever end of the temperature sensor 14 can be further reduced, thereby improving the support stability of the temperature sensor 14.

[0102] In some embodiments, as shown in Figure 2, the shell 10' includes a first part 11, the first part 11 is used to form an air inlet channel 13, the first part 11 includes a first section 111 and a second section 112, the first section 111 and the second section 112 are split structures, the second section 112 forms an air inlet 131, and the first section 111 is connected to one end of the second section 112 away from the air inlet 131, and the support structure 16 is arranged in the second section 112.

[0103] For example, the first portion 11 may be cylindrical. During assembly, the support structure 16 may be connected to the second section 112 to form an assembly, or the support structure 16 and the second section 112 may be integrally formed, and then the assembly as a whole may be connected to the first section 111 by welding or other means.

[0104] This embodiment takes into account that the first portion 11 is a slender cylindrical structure, designs the first portion 11 as a segmented structure, and arranges the support structure 16 in the second segment 112. Since the second segment 112 is relatively short, especially when multiple support structures 16 are arranged, the support structure 16 can be conveniently fixed in the second segment 112, thereby reducing the process difficulty and improving the positioning accuracy of the support structure 16.

[0105] In some embodiments, the shell 10' also includes a first part 11 and a second part 12, the first part 11 is used to form an air intake channel 13, the second part 12 is connected to the side of the first part 11 away from the air intake port 131, and a fixing seat 18 is provided in the second part 12. The fixing seat 18 is provided with a first through hole 181 and a mounting groove 182 side by side. The temperature sensor 14 passes through the first through hole 181 and extends in the air intake channel 13. The air pressure sensor 15 is provided in the mounting groove 182, and the mounting groove 182 is connected to the air intake channel 13.

[0106] Both the first portion 11 and the second portion 12 may be cylindrical, for example, with a cylindrical structure. The first portion 11 forms the air inlet passage 13, through which the temperature sensor 14 passes, thereby reducing the diameter of the mounting interface. The second portion 12 has a larger diameter than the first portion 11 and is used to mount the temperature sensor 14 and the air pressure sensor 15. The end of the second portion 12 near the first portion 11 is connected to the first portion 11 at the junction, and the rest of the second portion 12 is closed. The first through hole 181 is coaxially arranged with the air inlet passage 13 to mount the temperature sensor 14. The air pressure sensor 15 is located to one side of the temperature sensor 14, and the two are arranged side by side. Therefore, the axis of the first portion 11 is offset relative to the axis of the second portion 12.

[0107] The second portion 12 has an opening at one end away from the first portion 11. The fixing base 18 is inserted through the opening and secured to the housing 10' by welding or other means. The temperature sensing portion 141 of the temperature sensor 14 can be sequentially passed through the first through-hole 181 and the air inlet passage 13 before exiting through the air inlet 131. This arrangement can prevent the first electrical lead 142 of the temperature sensor 14 from interfering with assembly and damaging it. Alternatively, the rear end of the temperature sensor 14 can be installed by sequentially passing through the air inlet passage 13 and the first through-hole 181. The pressure sensor 15 can be installed directly through the notch of the mounting slot 182.

[0108] Optionally, the connection between the first portion 11 and the second portion 12 can be integrally formed, which can simplify the processing of the housing 10' and improve the sealing performance of the housing 10'. Specifically, the second portion 12 is integrally formed with the first section 111. Alternatively, the first portion 11 and the second portion 12 can be separate structures and connected by welding or other methods.

[0109] This embodiment can conveniently realize the installation and fixation of the temperature sensor 14 and the air pressure sensor 15, and the assembly process is relatively simple. The installation groove 182 is connected with the air intake passage 13, so that the intake air can smoothly reach the air pressure sensing part 151 of the air pressure sensor 15 to realize air pressure detection.

[0110] In some embodiments, the mounting groove 182 is opened on the surface of the fixing seat 18 away from the first part 11, the bottom surface of the mounting groove 182 is provided with a second through hole 183, and the end surfaces connecting the fixing seat 18 and the second part 12 and the first part 11 are spaced apart to form an air guide channel 184, and the mounting groove 182 is connected to the air intake channel 13 through the second through hole 183 and the air guide channel 184.

[0111] Among them, after the air pressure sensor 15 is fixed in the mounting groove 182, there is still a certain distance between the air pressure sensing portion 151 and the bottom surface of the mounting groove 182, so that the gas introduced by the second through hole 183 can cover the entire area of ​​the air pressure sensing portion 151, thereby causing the entire surface of the air pressure sensing portion 151 to deform under the action of the gas pressure, thereby improving the accuracy of air pressure detection.

[0112] This embodiment provides the second through hole 183 and the air guide channel 184 so that the gas enters the housing 10 ′ through the air inlet channel 13 and then passes through the air guide channel 184 and the second through hole 183 to smoothly reach the air pressure sensing portion 151 , thereby improving the accuracy of air pressure detection.

[0113] In some embodiments, the sensing device further includes a sealing member 17 , which is disposed between the air pressure sensor 15 and the mounting groove 182 .

[0114] For example, as shown in FIG2 , the mounting groove 182 is a stepped groove, and the sealing member 17 is an annular sealing ring disposed at the bottom of the stepped groove. When the air pressure sensor 15 is installed in place, the sealing member 17 is located between the bottom of the stepped groove and the step on the outer wall of the air pressure sensor 15 to achieve sealing. Alternatively, an annular groove is provided on the outer wall of the air pressure sensor 15, and the sealing ring is embedded in the annular groove to achieve sealing.

[0115] This embodiment can achieve sealing of the air pressure sensor 15 by providing a seal 17, thereby preventing gas from leaking from the gap between the air pressure sensor 15 and the mounting groove 182, thereby improving the accuracy of air pressure detection; and when the stored medium is gas or volatile liquid, it can prevent the medium from escaping.

[0116] In some embodiments, the temperature sensor 14 is welded to the first through hole 181 at least at its outer end over the entire circumference; and / or the air pressure sensor 15 is welded to the mounting groove 182 at least at its outer end over the entire circumference.

[0117] The outer end of the temperature sensor 14 refers to the end away from the air intake passage 13, and the outer end of the air pressure sensor 15 refers to the end away from the air intake passage 13. For example, laser welding can be used.

[0118] This embodiment welds the outer ends of temperature sensor 14 or pressure sensor 15, facilitating the welding process and reducing the complexity of the process. Furthermore, by welding along the entire circumference of temperature sensor 14 or pressure sensor 15, the weld fills the installation gap, preventing gas leakage and providing a seal. Combining full-circumference welding with seal 17 achieves a double seal, enhancing sealing effectiveness and reliability.

[0119] In some embodiments, as shown in Figure 2, the sensing device 10 also includes a circuit board 19, which is arranged on a side of the temperature sensor 14 and the air pressure sensor 15 away from the air intake passage 13; the air pressure sensor 15 is located on the side of the temperature sensor 14, and the first electrical lead 142 of the temperature sensor 14 and the second electrical lead 152 of the air pressure sensor 15 are both led out toward one end close to the circuit board 19 and are electrically connected to the circuit board 19.

[0120] The circuit board 19, also known as a printed circuit board (PCB), is used to amplify and condition the detection signals from the temperature sensor 14 and the air pressure sensor 15, and output the signals. The circuit board 19 is located on the side of the mounting base 18 away from the air inlet passage 13.

[0121] In this embodiment, circuit board 19 is positioned on the side of temperature sensor 14 and pressure sensor 15 away from intake passage 13. This prevents high humidity from reaching circuit board 19, first electrical lead 142, and second electrical lead 152, potentially impacting operational reliability and preventing detection failure. Furthermore, in the presence of corrosive media, this prevents gas from reaching circuit board 19, first electrical lead 142, and second electrical lead 152, potentially causing corrosion, thereby extending the service life of sensor device 10. Furthermore, this structure facilitates installation of circuit board 19 from the opening of housing 10' away from intake passage 13, and facilitates electrical connection between first and second electrical lead 142, 152 and circuit board 19.

[0122] On the basis of this structure, the temperature sensor 14 is welded to the first through hole 181 at least at the outer end in the entire circumference, and the pressure sensor 15 is welded to the mounting groove 182 at least at the outer end in the entire circumference. This can isolate the first electrical lead 142 and the second electrical lead 152 from the medium in the shell 10', preventing gas leakage from affecting the working reliability of the circuit board 19, the first electrical lead 142 and the second electrical lead 152.

[0123] In some embodiments, the temperature sensor 14 and the air pressure sensor 15 are flush with one end close to the circuit board 19 .

[0124] The plane formed by the outer end of the temperature sensor 14 , the outer end of the air pressure sensor 15 and the fixing seat 18 supports the circuit board to improve the installation stability of the circuit board 19 .

[0125] To protect the circuit board 19 , the end of the second portion 12 extends beyond the outer surface of the circuit board 19 .

[0126] This embodiment makes the temperature sensor 14 and the air pressure sensor 15 flush with one end close to the circuit board 19, so that the first electrical lead-out portion 142 and the second electrical lead-out portion 152 can extend to the same length when connected to the circuit board 19, and also facilitates electrical connection with the circuit board 19; moreover, when the outer end faces of the temperature sensor 14 and the air pressure sensor 15 exceed the installation surface, the temperature sensor 14 and the air pressure sensor 15 can jointly provide support for the circuit board 19, thereby improving the installation stability of the circuit board 19.

[0127] In some embodiments, both the temperature sensor 14 and the air pressure sensor 15 have metal packages.

[0128] To improve corrosion resistance, stainless steel packaging can be used. For example, the air pressure sensor 15 can use, but is not limited to, an oil-filled core air pressure sensor encapsulated in stainless steel; the temperature sensor 14 can use, but is not limited to, a platinum resistance temperature sensor encapsulated in a stainless steel straight tube. The length of the platinum resistance temperature sensor can be adjusted according to specific test requirements.

[0129] This embodiment can protect the internal structure by metal packaging of the sensor, improve the corrosion resistance, and increase the working reliability and service life of the sensor.

[0130] The sensor devices 10 of the aforementioned embodiments can all be used in a storage container 100 , mounted on a container body 20 . Because this integrated temperature and pressure sensor device 10 surrounds the air inlet channel 13 around the periphery of the temperature sensor 14 , the diameter of the mounting area of ​​the sensor device 10 can be reduced. Therefore, even when the mounting aperture in the container body 20 is relatively small, this facilitates meeting mounting requirements and allows for measurement of the temperature and pressure of the medium stored within the container body 20 .

[0131] Optionally, since the temperature sensor 14 and the pressure sensor 15 are both metal-encapsulated, the housing 10 ′ can be made of corrosion-resistant metal. Therefore, when corrosive media is stored in the container body 20 , the temperature and pressure can be stably and reliably measured for a long time.

[0132] Optionally, since the circuit board 19, the first electrical lead 142 and the second electrical lead 152 are arranged at the outer end of the sensor and are sealed by providing a seal 17 and / or welding the entire circumference of the outer end, the corrosive medium can be separated from the circuit board 19, the first electrical lead 142 and the second electrical lead 152, which can improve the reliability of the detection of the medium in the container body 20 and improve the service life of the sensing device 10.

[0133] Optionally, a support structure 16 is provided between the temperature sensor 14 and the housing 10 ′ to provide stable support for the temperature sensor 14 to prevent it from shaking, and to form an air inlet channel 13 to improve the reliability and stability of the sensing device 10 in detecting the medium in the container body 20 .

[0134] In some embodiments, a third through hole 201 is defined in the container body 20 , and an end of the shell 10 ′ close to the temperature sensor 14 is installed in the third through hole 201 .

[0135] During installation, an axial positioning structure is provided between the third through hole 201 and the installation interface on the housing 10 ′ to define the relative position between the housing 10 ′ and the third through hole 201 .

[0136] In this embodiment, the mounting interface of the sensor device 10 is located at one end of the housing 10' close to the temperature sensor 14. Thus, after installation, there is still a spacing distance between the mounting surface of the container body 20 and the second portion 12 with a larger cross-sectional area. Even if there are protrusions or slopes on the mounting surface, they can be avoided, thereby improving the adaptability of the sensor device 10 to mounting surfaces of different shapes.

[0137] In some embodiments, the third through hole 201 is a threaded hole, and an end of the housing 10 ′ close to the air inlet 131 is provided with an external thread 113 that matches the threaded hole.

[0138] This embodiment provides external threads 113 on the housing 10' as a mounting interface. This provides a simple structure, ease of machining, and convenient assembly and disassembly. It also facilitates fine-tuning of the sensor device 10's mounting height after installation, adjusting the height of the temperature sensing portion 141 based on detection requirements. Furthermore, positioning the external threads 113 near the air inlet 131 on the housing 10' helps avoid protruding structures on the mounting surface of the container body 20 after installation.

[0139] In some specific embodiments, as shown in Figures 1 to 3, a storage container 100 includes a container body 20 and a sensor device 10. The container body 20 is configured to store a medium, and the sensor device 10 is mounted on the container body 20, for example, on the top wall or side wall of the container body 20. The container body 20 is provided with a third through hole 201, which is a threaded hole. The end of the housing 10' near the air inlet 131 is provided with an external thread 113 that mates with the threaded hole.

[0140] The sensing device 10 includes a shell 10', in which an air inlet channel 13 is provided, and the air inlet channel 13 has an air inlet port 131; at least a portion of the temperature sensor 14 is provided in the shell 10' and is configured to detect temperature. The air inlet channel 13 surrounds the outer periphery of the temperature sensor 14, and the air inlet channel 13 and the temperature sensor 14 can be coaxially arranged. The temperature sensing portion 141 of the temperature sensor 14 extends out of the air inlet port 131 on the shell 10'. In the installed state, if the medium is liquid, the temperature sensing portion 141 contacts the liquid surface or extends into the liquid surface; at least a portion of the air pressure sensor 15 is provided in the shell 10', and the air pressure sensing portion 151 of the air pressure sensor 15 is connected to the air inlet channel 13 and is configured to detect air pressure.

[0141] The sensing device 10 also includes a circuit board 19, which is arranged on a side of the temperature sensor 14 and the air pressure sensor 15 away from the air intake passage 13; the air pressure sensor 15 is located on the side of the temperature sensor 14, and the first electrical lead 142 of the temperature sensor 14 and the second electrical lead 152 of the air pressure sensor 15 are both led out toward one end close to the circuit board 19 and are electrically connected to the circuit board 19.

[0142] The housing 10' further includes a first portion 11 and a second portion 12, both of which are cylindrical. The first portion 11 is used to form an air inlet passage 13, and the second portion 12 is connected to the side of the first portion 11 away from the air inlet 131. The second portion 12 has a larger diameter than the first portion 11. A fixing seat 18 is provided within the second portion 12. The fixing seat 18 is provided with a first through-hole 181 and a mounting groove 182 arranged side by side. The temperature sensor 14 passes through the first through-hole 181 and extends within the air inlet passage 13. The air pressure sensor 15 is provided within the mounting groove 182. The bottom surface of the mounting groove 182 is provided with a second through-hole 183. The fixing seat 18 and the end surface where the second portion 12 and the first portion 11 are connected are spaced apart to form an air guide passage 184. The mounting groove 182 communicates with the air inlet passage 13 via the second through-hole 183 and the air guide passage 184. In the installed state, the gas can pass through the air inlet channel 13, the air guide channel 184 and the second through hole 183 in sequence to reach the air pressure sensing portion 151 to achieve air pressure detection.

[0143] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts.
