[0015] In one embodiment, the detection device further includes a display unit for displaying the detection result of the test piece, the display unit being fixedly mounted on the surface of the housing; and a control unit for controlling the display of the detection result on the display unit when the test piece contacts the test piece.

[0016] In one embodiment, the detection device further includes an anti-slip part disposed on the outer surface of the housing, the anti-slip part protruding on the outer surface of the housing.

[0017] In one embodiment, the detection device further includes a bracket mounted on a first outer surface of the housing.

The first portion has a first end facing away from the second portion, and the second portion has a second end facing away from the first portion.

[0018] Wherein, the angle between the direction of the first end pointing to the connecting end and the direction perpendicular to the first outer surface and away from the housing is 30 degrees to 45 degrees; and / or

[0038] Reference Figure 1 , Figure 2 and Figure 3 , Figure 1 This paper shows a three-dimensional structural schematic diagram of the detection device 100 in some embodiments of this application. Figure 2 It shows Figure 1 Rear view of the detection device 100 in the middle. Figure 3 It shows Figure 1 A cross-sectional schematic diagram of the cooling element 3 in some embodiments of the detection device 100. Embodiments of this application provide a detection device 100, including a housing 1, a detection element 2, a control element, and a cooling element 3. The housing 1 has a receiving cavity, an inlet R, and an outlet C. The inlet R communicates with the receiving cavity, allowing heat exchange medium that has not undergone heat exchange to enter the receiving cavity of the housing 1 from the inlet R. The receiving cavity communicates with the outlet C, allowing the heat exchange medium entering the receiving cavity to flow out of the housing 1 from the outlet C after heat exchange is completed.

[0039] Continue to refer to Figures 1 to 3A cooling element 3 is provided in the receiving cavity, and a medium channel FD is opened inside the cooling element 3. The medium channel FD has a medium inlet JF and a medium outlet CF. The medium inlet JF is connected to the inlet R, and the medium outlet CF is connected to the outlet C. The cooling element 3 is used to surround the outside of the electronic components in the receiving cavity. In this way, the heat exchange medium can reach the medium inlet JF from the inlet R, enter the cooling element 3, and be discharged from the medium outlet CF through the medium channel FD. The flow of the heat exchange medium in the medium channel FD reduces the temperature of the outer surface of the cooling element 3. The outer surface of the cooling element 3 can contact the electronic components in the receiving cavity for heat exchange. Since the electronic components are in a heated state during use, the temperature of the cooling element 3 is lower than the temperature of the electronic components. The cooling element 3 can exchange heat with the electronic components, thereby reducing the temperature of the electronic components.

[0040] Continue to refer to Figure 2 The control unit and the detection unit 2 in the detection device 100 are electrically connected. When the detection device 100 performs detection, the detection unit 2 can contact the object to be detected for detection. When the control unit senses that the detection unit 2 is being detected, it can control the opening of the inlet R and outlet C of the housing 1, realizing the communication between the inside and outside of the housing 1, and allowing the heat exchange medium to enter and exit the housing 1. The control unit and the detection unit 2 can be connected via wired or wireless means.

[0041] In this way, the cooling component 3 contacts and exchanges heat with the electronic components inside the housing 1, thereby reducing the heat of the electronic components inside the housing 1 and cooling the detection device 100.

[0042] In some embodiments of this application, reference continues to be made to... Figures 1 to 3 The detection device 100 also includes two wind deflectors 3 that are movably disposed relative to the housing 1 at the inlet R and the outlet C. The wind deflectors 3 are configured to open the inlet R and the outlet C in response to the movement of the detection element 2 when the detection element 2 is in the detection state.

[0043] The baffle 3, through its movable design, can automatically open or close the inlet R and outlet C in response to the movement state of the detection element 2. This linkage mechanism ensures that the flow channel between the outside and the inside of the housing 1 is only opened when the detection device 100 needs to perform detection, thus preventing the risk of external impurities entering the housing 1 when detection is not required. Furthermore, in this application, the relative position of the baffle 3 and the housing 1 can be adjusted according to the heat dissipation requirements of the detection device 100, controlling the amount of heat exchange medium entering the housing 1, thereby regulating the overall heat dissipation effect of the detection device 100.

[0044] In some embodiments of this application, reference continues to be made to... Figure 3The cooling component 3 includes a spiral segment LD, and a spiral medium channel FD extending in the spiral direction is opened inside the spiral segment LD. The medium channel FD includes the spiral medium channel FD, and the spiral segment LD is used to surround the outside of the electronic component in the housing cavity.

[0045] The arrangement of the spiral segment LD not only makes the cooling component 3 more compact and occupies less space when installed in the housing cavity, but also serves as a structural support component as the spiral segment LD is arranged around the outside of the electronic component.

[0046] In some other embodiments, the medium channel FD can also be configured as a straight line, which is easier to process and form. Compared with the straight medium channel FD, the spiral medium channel FD adopted in this application extends the flow distance of the airflow in a limited space through the curved path, thereby increasing the contact time between the cooling component 3 and the electronic components. The inner wall surface area of ​​the medium channel FD of the spiral segment LD is about twice that of the straight medium channel FD, which increases the contact area between the cooling component 3 and the electronic components, thereby improving the heat dissipation capacity of the cooling component 3.

[0047] In some embodiments of this application, the inlet R and the outlet C are located on the same side of the housing 1.

[0048] By placing the inlet R and outlet C on the same side of the housing 1, this side-by-side arrangement reduces the need for multiple openings on the housing 1, freeing up installation space on other sides. Correspondingly, the structure of the cooling component 3 installed within the receiving cavity can be adopted... Figure 3 As shown in the diagram, cooling component 3 occupies less space.

[0049] In some embodiments of this application, reference may be made to Figure 1 The inlet R and outlet C are located on different sides of the housing 1. For example, they can be located on opposite sides of the housing 1. The structure of the cooling element 3 can be configured as follows: Figure 4 The structure shown is as follows. This arrangement physically isolates the inlet R and outlet C on different sides, reducing the risk of the hot, heat-exchanged air discharged from outlet C being re-entered into inlet R. Specifically, in this application, the heat exchange medium is cold air at 10 to 15 degrees Celsius. By placing inlet R and outlet C on opposite sides of the casing 1, the risk of the hot, heat-exchanged air being re-drawn into inlet R is reduced.

[0050] In some embodiments of this application, reference continues to be made to... Figure 1 middle Figure 3 and in conjunction with reference Figure 4 , Figure 4 It shows Figure 1A cross-sectional schematic diagram of the cooling element 3 in some embodiments of the detection device 100. Further, the cooling element 3 also includes a first straight section PD1 and a second straight section PD2 extending along the axial direction of the spiral segment LD, respectively disposed at opposite ends of the spiral segment LD; the first straight section PD1 has a first cavity Q1, which is connected to both the medium channel FD and the inlet R; the second straight section PD2 has a second cavity Q2, which is connected to both the medium channel FD and the outlet C. The medium inlet JF of the cooling element 3 is connected to the inlet R of the housing 1, and the medium outlet CF of the cooling element 3 is connected to the outlet C of the housing 1. At this time, the inlet R and the outlet C are located on opposite sides of the housing 1. The arrangement of the first straight section PD1 and the second straight section PD2 provides a smooth fluid channel, reducing turbulence and vortices at the inlet R and outlet C of the spiral segment LD, allowing the fluid to enter and leave the spiral segment LD more smoothly. Furthermore, since the heat exchange medium tends to have a larger flow rate at the inlet R and outlet C, the straight section helps to evenly distribute the fluid pressure. However, pressure abrupt changes occur at the beginning and end of the spiral section LD, which can damage the cooling component 3.

[0051] In some embodiments of this application, reference continues to be made to... Figures 1 to 3 The display unit 4 is fixedly mounted on the surface of the housing 1, and the control unit is used to control the display of the detection result on the display unit 4 when the detection unit 2 comes into contact with the detection unit 2.

[0052] By providing a display unit 4, the data or results detected by the test piece 2 can be directly and intuitively displayed, allowing the operator to obtain information without other operations or calculations, thus improving the convenience and efficiency of operation. Furthermore, the display unit can show the test data in real time, enabling the operator to immediately understand the test status and results, facilitating timely responses and adjustments.

[0053] In some embodiments of this application, reference continues to be made to... Figures 1 to 3 The detection device 100 also includes an anti-slip part 5, which is disposed on the outer surface of the housing 1 and protrudes from the outer surface of the housing 1. The anti-slip part 5 increases the roughness of the surface of the housing 1 through its protruding design, thereby increasing the friction with the hand or other contact objects and reducing the risk of the detection device 100 slipping or shifting during use. The protruding anti-slip part 5 provides a better grip, allowing the operator to hold the device more stably, especially in situations requiring precise operation or prolonged use, reducing operational errors caused by hand slippage and improving the accuracy and repeatability of the detection.

[0054] In some embodiments of this application, reference continues to be made to... Figures 1 to 4 and in conjunction with reference Figure 5 and Figure 6 , Figure 5 It shows Figure 1A three-dimensional structural diagram of the detection device 100 from another angle. Figure 6 It shows Figure 1 The detection device 100 is shown in the side view. The detection device 100 also includes a bracket 6, which is mounted on the first outer surface M1 of the housing 1. The bracket 6 includes a first portion 61 and a second portion 62 connected to each other via a connecting end D3. The first portion 61 has a first end D1 facing away from the second portion 62, and the second portion 62 has a second end D2 facing away from the first portion 61. The angle between the direction in which the first end D1 points towards the connecting end D3 and the direction perpendicular to the first outer surface M1 and facing away from the housing 1 is 30 to 45 degrees; and / or, the angle between the direction in which the connecting end D3 points towards the second end D2 and the direction in which the first end D1 points towards the connecting end D3 is 45 to 60 degrees.

[0055] In the case where "the detection device 100 also includes a bracket 6, which is mounted on the first outer surface M1 of the housing 1, and the bracket 6 includes a first part 61 and a second part 62 connected to each other, the first part 61 and the second part 62 are connected by a connecting end D3, the first part 61 has a first end D1 facing away from the second part 62, and the second part 62 has a second end D2 facing away from the first part 61; wherein the angle between the direction in which the first end D1 points to the connecting end D3 and the direction perpendicular to the first outer surface M1 and facing away from the housing 1 is 30 degrees to 45 degrees", the design of the bracket 6 makes the detection device 100 more stable when placed and less prone to tipping over. The angle design of the first part 61 and the second part 62 not only helps to distribute gravity, but also increases the contact area between the second part 62 and the placement surface by setting the direction in which the first end D1 points to the connecting end D3 and the direction perpendicular to the first outer surface M1 and facing away from the housing 1 at 30 degrees to 45 degrees, thereby improving the overall stability. At this time, the display part 4 can be tilted, which makes it easier for the operator to read the value.

[0056] With the following configuration, the detection device 100 also includes a bracket 6, which is mounted on the first outer surface M1 of the housing 1. The bracket 6 includes a first part 61 and a second part 62 connected to each other. The first part 61 and the second part 62 are connected by a connecting end D3. The first part 61 has a first end D1 facing away from the second part 62, and the second part 62 has a second end D2 facing away from the first part 61. The angle between the direction in which the connecting end D3 points to the second end D2 and the direction in which the first end D1 points to the connecting end D3 is 45 degrees to 60 degrees, the structure is more stable. The detection device 100 can effectively resist forces and torques from all directions, so that the detection device 100 will not easily tilt or collapse during operation.

[0057] The aforementioned "detection device 100 further includes a bracket 6, which is mounted on the first outer surface M1 of the housing 1. The bracket 6 includes a first part 61 and a second part 62 connected to each other. The first part 61 and the second part 62 are connected by a connecting end D3. The first part 61 has a first end D1 facing away from the second part 62, and the second part 62 has a second end D2 facing away from the first part 61; wherein the first end D1 points in the direction of the connecting end D3, and the angle between this direction and the direction perpendicular to the first outer surface M1 and facing away from the housing 1 is 30 degrees to 45 degrees." The detection device 100 also includes a bracket 6, which is mounted on the first outer surface M1 of the housing 1. The bracket 6 includes a first part 61 and a second part 62 connected to each other. The first part 61 and the second part 62 are connected by a connecting end D3. The first part 61 has a first end D1 facing away from the second part 62, and the second part 62 has a second end D2 facing away from the first part 61. The angle between the direction of the connecting end D3 pointing to the second end D2 and the direction of the first end D1 pointing to the connecting end D3 is 45 degrees to 60 degrees, and can be arbitrarily combined in actual situations.

[0058] In some embodiments of this application, reference continues to be made to... Figures 5 to 6 and in conjunction with reference Figure 7 , Figure 7 It shows Figure 1 The top view of the detection device 100 is shown. The bracket 6 also includes a third part 63, which is connected to the first outer surface M1 and the first part 61. The cross-sectional area of ​​the third part 63 is larger than that of the first part 61 in a direction perpendicular to the first outer surface M1. And / or, in a direction perpendicular to the connecting end D3 pointing to the second end D2, the second part 62 is provided with a mounting groove AN. The mounting groove AN extends in the direction from the third end to the fourth end and is used to mount the detection piece 2.

[0059] In the case where "the bracket 6 also includes a third part 63, which is connected to the first outer surface M1 and the first part 61, and the cross-sectional area of ​​the third part 63 is larger than that of the first part 61 in the direction perpendicular to the first outer surface M1," the addition of the third part 63 increases the overall rigidity of the bracket 6. Because the cross-sectional area of ​​the third part 63 is larger than that of the first part 61, it can provide greater support force when subjected to forces perpendicular to the first outer surface M1, thereby enhancing the stability of the entire structure. The larger cross-sectional area also means that the third part 63 can withstand greater loads without deformation or damage. Furthermore, the third part 63 provides additional support points and a larger contact surface, making it easier for installers to connect the first outer surface M1 of the housing 1 to the third part 63 of the bracket 6.

[0060] In the configuration where "a mounting groove AN is provided in the second part 62 in the direction perpendicular to the connecting end D3 pointing to the second end D2; the mounting groove AN extends in the direction from the third end to the fourth end, and the mounting groove AN is used to install the detection element 2," the mounting groove AN provides an installation position for the detection element 2, and makes the installation and removal of the detection element 2 more convenient. The placement of the detection element 2 can be completed through a simple sliding or fixing operation, which also facilitates future maintenance and replacement. Specifically, in this application, multiple mounting grooves AN can be provided to accommodate more detection elements 2.

[0061] Furthermore, this application may also be configured with a wireless communication module 8, etc., to wirelessly transmit the data detected by the detection component 2 directly to the system terminal, etc. This application also includes a control button 7 to adjust the adjustment mode of the detection component 2.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
