[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0037] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0038] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] Please refer to Figures 1 to 3. This application embodiment provides a detection device, including a housing 1 and a temperature detection component 2. The housing 1 has a first accommodating space 11 and a first opening 12 communicating with the first accommodating space 11. The temperature detection component 2 includes an extension section 21 and a connecting section 22. The temperature detection component 2 passes through the first opening 12, such that the connecting section 22 is located within the first accommodating space 11. The extension section 21 extends out of the first accommodating space 11 from the first opening 12 and has a temperature detection position 211.

[0040] In the above-mentioned detection device, the protruding section 21 has a temperature detection position 211, which is used to detect the temperature of the environment to be measured. The protruding section 21 extends out of the first accommodating space 11 from the first opening 12, which means that the temperature detection position 211 extends out of the first accommodating space 11, reducing the contact area between the temperature detection position 211 and the outer shell 1, or making the temperature detection position 211 separated from the outer shell 1, avoiding excessive heat transfer from the outer shell 1 to the temperature detection position 211, reducing the degree to which the temperature detection position 211 is affected by the outer shell 1, and improving the detection accuracy of the detection device.

[0041] Understandably, the temperature sensing component 2 includes an extension section 21 and a connecting section 22. The connecting section 22 is located within the first accommodating space 11. The connecting section 22 is electrically connected to a predetermined component located within the first accommodating space 11, enabling the predetermined component to acquire the temperature of the environment to be measured based on the detection result of the temperature sensing component 2. For example, the predetermined component includes a circuit board. The connecting section 22 is electrically connected to the circuit board, and the temperature sensing component 2 can transmit a signal to the circuit board, allowing the circuit board to process the signal and acquire the temperature of the environment to be measured.

[0042] It is worth noting that the environment to be tested includes, but is not limited to, liquid and gaseous environments. For ease of explanation, the embodiments of this application mainly use the detection device for detecting liquid environments as an example.

[0043] In some embodiments, the first body 101 and the second body 102 are sealed together, and the first body 101 and the second body 102 enclose a first accommodating space 11 to prevent liquid in the liquid environment from seeping into the first accommodating space 11 when the detection device is used to detect the liquid environment, thereby protecting the internal components of the first accommodating space 11.

[0044] In some embodiments, the detection device further includes a depth detection component (not shown) and a control component (not shown). The depth detection component is used to detect the depth of the detection device in the liquid. The control component is electrically connected to the temperature detection component 2 and the depth detection component. The control component is used to determine the temperature of the liquid at a preset depth based on the detection results of the depth detection component and the temperature detection component 2. It is understood that the temperature of the liquid may be different at different depths. Through the control component being electrically connected to the temperature detection component 2 and the depth detection component, the depth detection component and the temperature detection component 2 can transmit the detection results to the control component. The control component can obtain the depth information of the detection device's location in the liquid and the temperature information of the liquid surrounding the location of the detection device based on the detection results, and correlate the depth information and temperature information to determine the temperature of the liquid at the preset depth.

[0045] For example, the control component may include a circuit board as described above, and the control component may be disposed within the first accommodating space 11.

[0046] For example, the depth detection component includes, but is not limited to, a pressure sensor and an echo sounder, and the depth detection component may be disposed within the first accommodating space 11. Taking the depth detection component including a pressure sensor as an example, when the detection device is at the surface of the liquid, the pressure sensor can be used to detect the reference air pressure. Then, when the detection device is at a certain depth in the liquid, the pressure sensor can detect the change in air pressure relative to the reference air pressure and convert the change in air pressure into a signal that is transmitted to the control component. The control component can determine the depth information of the detection device in the liquid based on the liquid pressure formula.

[0047] In some embodiments, the detection device can operate in liquid environments such as lakes and rivers and detect the temperature of the liquid at different depths. For example, the detection device can sink in the liquid environment under the influence of gravity, or it can be connected to a transmission component and move in the liquid environment under the drive of the transmission component, such as sinking, rising, or moving horizontally. Specifically, the detection device can detect the temperature of the liquid at different depths while sinking or rising, or it can sink or rise to a certain depth, stop, and then detect the temperature of the liquid at that depth. After detection, it can continue to sink or rise to another depth, stop again, and then detect again to measure the temperature of the liquid at different depths.

[0048] Furthermore, the control component can determine the depth range corresponding to the portion of the liquid that meets the preset temperature range based on the temperature of the liquid at different depths.

[0049] For example, the detection device can be placed on the lake surface, and then the detection device sinks from the lake surface to the bottom of the lake under the action of gravity. During the sinking process, the detection device can obtain the temperature of the lake water at different depths and divide the lake water into multiple depth ranges according to different temperature ranges. Fish usually move in areas that meet their suitable temperature range. By using the suitable temperature range of the fish as the preset temperature area, the depth range in which the fish are distributed in the lake water can be determined.

[0050] In one exemplary embodiment, the detection device includes a display screen, and a control component electrically connected to the display screen, the control component being capable of controlling the display screen to display predetermined information. For example, the display screen may display the temperature of the liquid at different depths, and / or the display screen may display the depth range corresponding to portions of the liquid that satisfy different temperature ranges.

[0051] Another example is that the control component can communicate with mobile terminals such as watches and mobile phones, and can transmit preset information to the mobile terminal. For example, the control component can transmit the temperature of liquid at different depths to the mobile terminal, and / or, the control component can transmit the depth range corresponding to the portion of liquid that meets different temperature ranges to the mobile terminal.

[0052] In some embodiments, the first opening 12 is located on the outer surface of the housing 1, and the protruding section 21 extends out of the first accommodating space 11 from the first opening 12, so that the protruding section 21 extends out of the housing 1, thereby reducing the contact area between the temperature detection position 211 and the housing 1, or the temperature detection position 211 is spaced apart from the housing 1.

[0053] As shown in Figure 2, in some embodiments, the outer casing 1 further has a second accommodating space 13, which communicates with the first accommodating space 11 through a first opening 12. The protruding section 21 is located in the second accommodating space 13 and is spaced apart from the wall of the second accommodating space 13. It is understood that the protruding section 21 extends into the second accommodating space 13 from the first opening 12. The outer casing 1 covers the outer periphery of the protruding section 21 to protect it from damage caused by impacts from external objects. Simultaneously, the protruding section 21 is spaced apart from the wall of the second accommodating space 13 to avoid the outer casing 1 affecting the detection accuracy of the temperature detection position 211.

[0054] Specifically, the radial dimension of the end of the connecting section 22 near the protruding section 21 can be matched with the opening size of the first opening 12, which can prevent liquid from seeping into the first accommodating space 11 from between the connecting section 22 and the outer casing 1. Alternatively, the radial dimension of the end of the connecting section 22 near the protruding section 21 can be slightly smaller than the opening size of the first opening 12, which facilitates the protruding section 21 to extend into the second accommodating space 13 from the first opening 12, while reducing the probability that the temperature detection component 2 will break due to excessive force between it and the outer casing 1 when the detection device vibrates.

[0055] As shown in Figures 2 and 3, the outer casing 1 further includes a second opening 14, which communicates with the second accommodating space 13, allowing the second accommodating space 13 to communicate with the outside of the outer casing 1. It is understood that since the second opening 14 connects the space outside the outer casing 1 and the second accommodating space 13, when the detection device is placed in a liquid environment such as a lake or river, the liquid in the liquid environment can enter the second accommodating space 13 through the second opening 14. This allows the temperature detection component 2 to contact the liquid to achieve temperature detection, improving the detection efficiency of the temperature detection component 2 and enhancing the accuracy of the detection results.

[0056] For example, there may be one or more second openings 14.

[0057] Specifically, when the detection device operates in a liquid environment, liquid at different locations can continuously enter the second containment space 13 through the second opening 14, enabling the temperature detection component 2 to contact the liquid at different locations in a timely manner and achieve temperature detection. For example, when the detection device sinks in a lake, lake water at different depths can enter the second containment space 13 through the second opening 14, enabling the temperature detection component 2 to detect the temperature of the lake water at different depths in a timely manner.

[0058] In some embodiments, the number of second openings 14 is at least two, and the two second openings 14 are arranged opposite to each other. It is understood that with two second openings 14, one can serve as an inlet and the other as an outlet. Liquid can enter the second accommodating space 13 from the inlet and then flow out of the second accommodating space 13 from the outlet. The opposite arrangement of the two second openings 14 facilitates the flow of liquid from the inlet to the outlet, improving the efficiency of liquid replacement within the second accommodating space 13. This allows the temperature detection position 211 to quickly contact the liquid at its current location for temperature detection, further improving the detection efficiency of the temperature detection component 2 and enhancing the accuracy of the detection results.

[0059] As shown in Figure 3, taking the detection device for detecting lake temperature as an example, the detection device sinks from the lake surface under the action of gravity. The two second openings 14 of the detection device can be arranged opposite each other in the direction of gravity, as shown in the Z direction of Figure 3. One of the two second openings 14 near the bottom serves as the inlet, and the one near the top serves as the outlet. The dashed line in Figure 3 shows the flow of lake water. As can be seen from Figure 3, during the sinking process of the detection device, the lake water in the second accommodating space 13 and the lake water outside the detection device can form rapid convection and exchange to improve the replacement efficiency of lake water in the second accommodating space 13. The temperature detection position 211 can quickly come into contact with lake water at different depths to achieve temperature detection. Of course, in other examples, the two second openings 14 can also be arranged opposite each other in directions other than the direction of gravity. The specific arrangement can be adjusted according to the actual situation and is not limited here.

[0060] Furthermore, the projection of the temperature detection position 211 onto a plane perpendicular to the first direction lies within the projection of the second opening 14 onto the plane, where the first direction is the arrangement direction of the two second openings 14. It is understood that since the first direction is the arrangement direction of the two second openings 14, when observing along the first direction, one second opening 14 can be seen from the other. Since the projection of the temperature detection position 211 onto a plane perpendicular to the first direction lies within the projection of the second opening 14 onto the plane, when observing along the first direction, the temperature detection position 211 can also be seen from the second opening 14. This helps ensure that the liquid flows from one second opening 14 to another through the temperature detection position 211, improving the liquid replacement efficiency around the temperature detection position 211. This ensures that the temperature detection position 211 can more quickly contact the liquid flowing into the second accommodating space 13 during the activity of the detection device, improving the detection accuracy of the temperature detection position 211 and increasing the detection efficiency of the temperature detection component 2.

[0061] For example, the first direction can be shown as the Z direction in Figure 3.

[0062] For example, the second accommodating space 13 extends along the first direction, and the plane perpendicular to the first direction of the second accommodating space 13 can be circular, reducing the resistance to the flow of liquid in the second accommodating space 13 and improving the efficiency of liquid replacement around the temperature detection position 211. In other examples, the plane perpendicular to the first direction of the second accommodating space 13 can also be elliptical or square, and can be adjusted according to the actual situation, which is not limited here.

[0063] Of course, in other embodiments, the projection of the temperature detection position 211 onto the plane perpendicular to the first direction may also be located outside the projection of the second opening 14 onto the plane. It is understood that when liquid enters the second accommodating space 13, it may carry impurities. By ensuring that the projection of the temperature detection position 211 onto the plane perpendicular to the first direction is located outside the projection of the second opening 14 onto the plane, the likelihood of impurities colliding with the temperature detection position 211 as the liquid flows can be reduced, thereby protecting the temperature detection component 2.

[0064] In some embodiments, the temperature sensing position 211 is located at the end of the extension 21 away from the connecting section 22, so that the temperature sensing position 211 is located as far away from the housing 1 as possible, thereby minimizing the influence of the housing 1 on the temperature sensing position 211.

[0065] In some embodiments, the extension length of the protruding section 21 is greater than or equal to 4 mm. It is understood that when the extension length of the protruding section 21 meets this condition, it is easier to space the temperature detection position 211 from the outer casing 1, reducing the degree to which the temperature detection position 211 is affected by the outer casing 1. Specifically, the extension length of the protruding section 21 can be 4 mm, 5 mm, 7 mm, etc.

[0066] For example, as shown in Figure 2, the protruding section 21 extends in a straight direction, and the protruding length of the protruding section 21 in the straight direction is greater than or equal to 4 mm.

[0067] Furthermore, the protruding section 21 extends along a straight line perpendicular to the first direction so that the protruding section 21 and the wall of the second accommodating space 13 are spaced apart, so that the distance from the temperature detection position 211 to the wall of the second accommodating space 13 is relatively uniform, thereby minimizing the influence of the outer shell 1 on the temperature detection position 211.

[0068] As shown in Figures 3 to 5, in some embodiments, the temperature sensing component 2 includes a housing 201, a thermocouple wire 202, and a heat conductor 203. The housing 201 has a first end 2011 and a second end 2012 facing away from each other. The first end 2011 is closed, and the second end 2012 has a third opening 20121. The thermocouple wire 202 has a temperature sensing section 2021 and an extension section 2022. Part of the extension section 2022 and the temperature sensing section 2021 extend from the third opening 20121 into the housing 201, and the temperature sensing section 2021 is located at the first end 2011. The heat conductor 203 fills the space between the housing 201 and the thermocouple wire 202. The temperature sensing position 211 includes the first end 2011 of the housing 201, the temperature sensing section 2021, and a portion of the heat conductor 203 located between the housing 201 and the temperature sensing section 2021. Understandably, the temperature detection component 2 can be a thermocouple. The thermocouple has a housing 201, a thermocouple wire 202, and a heat conductor 203. The heat of the environment to be measured can be transferred through the housing 201 and the heat conductor 203 to the temperature measuring section 2021 of the thermocouple wire 202, so that the thermocouple wire 202 generates a thermoelectric potential and forms a signal output to a predetermined component, which can obtain the temperature of the environment to be measured.

[0069] Specifically, the housing 201 protects the thermocouple wire 202 and the heat conductor 203. The housing 201 can be made of materials such as stainless steel, aluminum, or copper. The housing 201 may have a receiving cavity, which is connected to a third opening 20121. The thermocouple wire 202 passes through the third opening 20121 and extends into the receiving cavity, and the heat conductor 203 fills the receiving cavity. The thermocouple wire 202 may include a first thermocouple wire 202 and a second thermocouple wire 202. The temperature-sensing section 2021 of the first thermocouple wire 202 and the temperature-sensing section 2021 of the second thermocouple wire 202 can be welded together to form a temperature-sensing point. The thermocouple wire 202 extends into the receiving cavity, such that the temperature-sensing point formed by the joint of the temperature-sensing section 2021 of the first thermocouple wire 202 and the temperature-sensing section 2021 of the second thermocouple wire 202 is located at the first end 2011, extending out of the first receiving space 11 along with the housing 201.

[0070] Furthermore, the shell 201 can be integrally molded with a closed first end 2011 and a third opening 20121 at the second end 2012, thereby improving the overall strength of the shell 201.

[0071] As shown in Figures 3 to 5, in some embodiments, the temperature detection component 2 further includes an insulating element 204, which is disposed on the outer periphery of the extension section 2022. By providing the insulating element 204 on the outer periphery of the extension section 2022 of the thermocouple wire 202, current leakage and short circuits are prevented from occurring due to mutual contact between the extension sections 2022 of the thermocouple wire 202.

[0072] For example, the outer periphery of the extension segment 2022 of the first thermocouple wire 202 and the extension segment 2022 of the second thermocouple wire 202 are provided with insulating members 204 to prevent the extension segment 2022 of the first thermocouple wire 202 and the extension segment 2022 of the second thermocouple wire 202 from contacting and conducting.

[0073] As shown in Figure 3, further, a portion of the insulating member 204 extends from the third opening 20121 into the housing 201, and a heat conductor 203 is provided between the insulating member 204 and the housing 201. It is understood that the portion of the thermocouple wire 202 extension 2022 exposed outside the heat conductor 203 can be bent to meet the wiring requirements in the detection device, allowing a portion of the insulating member 204 to extend into the housing 201. The heat conductor 203 is provided between the insulating member 204 and the housing 201, meaning that the portion of the thermocouple wire 202 extension 2022 near the heat conductor is covered by the insulating member 204. The insulating member 204 can protect the thermocouple wire 202, enhance its strength, and reduce the probability of bending and breakage of the portion of the thermocouple wire 202 extension 2022 near the heat conductor.

[0074] For example, the insulating element 204 includes insulating adhesive or a flexible insulating tube. For instance, the insulating element 204 includes insulating adhesive, which can be applied to the outer periphery of the extensions 2022 of the first thermocouple wire 202 and the extensions 2022 of the second thermocouple wire 202 by means of coating; or, the insulating element 204 includes a flexible insulating tube, which is sleeved on the outer periphery of the extensions 2022 of the first thermocouple wire 202 and the extensions 2022 of the second thermocouple.

[0075] For example, after filling the housing 201 with thermally conductive material through the third opening 20121 of the housing 201, the thermocouple wire 202 is inserted into the thermally conductive material through the third opening 20121, so that the temperature measuring section 2021 of the thermocouple wire 202 is located inside the thermally conductive material, and part of the extension section 2022 and the insulating part 204 on the outer periphery of the extension section 2022 are located inside the thermally conductive material. Finally, the thermally conductive material is cured to form a heat conductor 203, thus obtaining the temperature detection component 2.

[0076] As shown in Figure 4, in some embodiments, the housing 201 includes a first segment 201a and a second segment 201b connected together. The radial dimension of the first segment 201a is smaller than the radial dimension of the second segment 201b. The first segment 201a and the second segment 201b together form a stepped structure, and the first segment 201a and the second segment 201b are integrally formed. It can be understood that the first segment 201a and the second segment 201b together form a stepped structure to facilitate the positioning of the housing 201 when it is installed on the outer shell 1. Furthermore, the integral forming of the first segment 201a and the second segment 201b simplifies the manufacturing process and improves the overall strength of the housing 201.

[0077] For example, as shown in Figures 3 and 4, the first segment 201a and the second segment 201b together form a stepped structure, with a first stepped surface formed between the first segment 201a and the second segment 201b. The first accommodating space 11 may include a first subspace and a second subspace that are connected, with a second stepped surface formed between the first subspace and the second subspace. The first segment 201a passes through the first subspace, and the second segment 201b passes through the second subspace. The first stepped surface can abut against the second stepped surface, thereby achieving a limiting fit between the temperature sensing component 2 and the outer shell 1, limiting the position of the temperature sensing component 2 relative to the outer shell 1, and achieving the positioning of the temperature sensing component 2. Specifically, the radial dimension of the first segment 201a can match the radial dimension of the first subspace, and / or the radial dimension of the second segment 201b can match the radial dimension of the second subspace, further achieving a limiting enclosure between the temperature sensing component 2 and the outer shell 1, limiting the position of the temperature sensing component 2 relative to the outer shell 1, and achieving the positioning of the temperature sensing component 2.

[0078] In some embodiments, the housing 201 has a protrusion that abuts against the wall of the first accommodating space 11, and the protrusion and housing 201 are integrally formed. By forming a protrusion on the outer periphery of the housing 201, it is easier to position the housing 201 when it is installed in the outer casing 1. The integral formation of the protrusion and housing 201 simplifies the manufacturing process, improves the overall strength of the temperature detection component 2, and prevents liquid in the liquid environment from seeping into the first accommodating space 11 between the protrusion and housing 201 when the detection device is used to detect the liquid environment.

[0079] The protrusions may be one or more. For example, the first space may include a first subspace and a second subspace that are connected to each other, with a second stepped surface formed between the first subspace and the second subspace. The housing 201 may pass through the first subspace and the second subspace, and the first end 2011 of the housing 201 extends out of the first accommodating space 11. The protrusions on the outer periphery of the housing 201 may abut against the second stepped surface to achieve a limiting fit between the temperature detection component 2 and the outer shell 1, thereby limiting the position of the temperature detection component 2 relative to the outer shell 1 and achieving the positioning of the temperature detection component 2.

[0080] For example, the protrusion includes an annular protrusion.

[0081] In some embodiments, the temperature sensing component 2 and the housing 1 are sealed together by a sealant 3 to prevent liquid in the liquid environment from seeping into the first accommodating space 11 from between the temperature sensing component 2 and the housing 1 when the sensing device is used to detect the temperature of the liquid environment, thereby achieving a seal for the sensing device.

[0082] For example, there may be one or more seals 3.

[0083] For example, the seal 3 can be made of elastic materials such as silicone or rubber to ensure good sealing performance.

[0084] For example, as shown in Figures 3 and 4, the shell 201 includes a third segment, a first segment 201a, and a second segment 201b arranged sequentially. The third segment, the first segment 201a, and the second segment 201b can all be hollow structures. The third segment, the first segment 201a, and the second segment 201b together form a receiving cavity. The end of the third segment away from the first segment 201a is sealed, and the end of the second segment 201b away from the first segment 201a has a third opening 20121. The radial dimensions of the third segment, the first segment 201a, and the second segment 201b gradually increase. The third segment and the first segment 201a together form a stepped structure, forming a third stepped surface between the third segment and the first segment 201a. The first segment 201a and the second segment 201b together form a stepped structure, forming a first stepped surface between the first segment 201a and the second segment 201b. The first receiving space 11 includes a connected third subspace, a first subspace, and a second subspace. A second stepped surface is formed between the first subspace and the second subspace, and a fourth stepped surface is formed between the third subspace and the first subspace. The first step surface abuts against the second step surface, defining the position of the temperature detection component 2 relative to the outer shell 1. The end of the third segment away from the first segment 201a extends out of the first accommodating space 11 through the first opening 12. A sealing element 3 is provided at the end of the third segment close to the first segment 201a. The sealing element 3 abuts against the outer surface of the third segment and the wall of the first subspace, realizing a sealed connection between the temperature detection component 2 and the outer shell 1. The position of the sealing element 3 is limited by the third step surface and the fourth step surface, preventing the sealing element 3 from coming out of the first subspace.

[0085] For example, the seal 3 can be configured as an annular ring to improve structural stability.

[0086] In some embodiments, the first accommodating space 11 is provided with a clamping member 4, and the temperature sensing component 2 is partially located between the housing 1 and the clamping member 4. The clamping member 4 is used to press the temperature sensing component 2 against the housing 1. It can be understood that the clamping member 4 is connected to the housing 1, and the clamping member 4 can make large-area contact with the temperature sensing component 2, so as to stably press the temperature sensing component 2 against the housing 1, thereby making the temperature sensing component 2 stably connected to the housing 1, and simplifying the connection structure of the temperature sensing component 2.

[0087] For example, the clamping member 4 can be fastened to the housing 1 by fasteners such as screws or bolts.

[0088] Of course, in other embodiments, the temperature sensing component 2 can also be connected to the housing 1 by adhesive bonding or threaded connection.

[0089] Furthermore, a filler 5 is provided between the clamping member 4 and the temperature detection component 2. The filler 5 can fill the gap between the clamping member 4 and the temperature detection component 2, ensuring that the temperature detection component 2 can be stably clamped onto the housing 1, thereby improving the connection stability between the temperature detection component 2 and the housing 1.

[0090] Furthermore, the filler 5 includes an elastic filler 5. Uneven areas may exist on the surfaces of the clamping member 4 and the temperature sensing component 2. By employing the elastic filler 5, it is easier to compensate for these uneven areas, allowing the clamping member 4 to more stably clamp the temperature sensing component 2.

[0091] For example, the elastic filler 5 includes, but is not limited to, foam, rubber, etc.
