Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0038] This application provides a detection device to solve the problem of detection devices being poorly sealed and prone to leakage and damage. The following description is in conjunction with the accompanying drawings.

[0039] In the embodiments of this application, such as Figure 1 as well as Figure 2 As shown, the detection device includes:

[0040] The detection box 1 is provided with a receiving cavity and a detection port 13 connecting the inside and outside of the receiving cavity;

[0041] The main control board 2 is provided with detection terminals 21. The main control board 2 is disposed within the receiving cavity, and the detection port 13 exposes the detection terminals 21; and,

[0042] Sealing sleeve 3;

[0043] The sealing sleeve 3 is fitted onto the detection terminal 21 and exposes the side of the detection terminal 21 facing the detection port 13, and the sealing sleeve 3 fits against the inner end of the detection port 13.

[0044] It should be noted that the detection terminal 21 is a component used to collect operating parameters such as air conditioner voltage, current, temperature, and pressure. The detection terminal 21 and the main control board 2 can be electrically connected through a plug-in plug and socket, or through screw crimping, or the wires of the detection terminal 21 can be soldered to the pads of the main control board 2 for permanent connection.

[0045] It is understandable that by setting the sealing sleeve 3 and putting the sealing sleeve 3 on the detection terminal 21, the periphery of the detection terminal 21 and the inner end of the detection terminal 21 and the detection port 13 are sealed, thereby improving the sealing and waterproof performance of the detection device and making the detection device more durable.

[0046] In some embodiments, such as Figure 3 as well as Figure 4 As shown, the detection terminal 21 is located near the side of the main control board 2. The sealing sleeve 3 includes a first sealing part 31 and a second sealing part 32. The first sealing part 31 extends along the surface of the main control board 2 and surrounds the detection terminal 21. The first sealing part 31 exposes the side of the detection terminal 21 facing the detection port 13. The second sealing part 32 is connected to the side of the first sealing part 31 facing the detection port 13 and exposes the detection terminal 21. The second sealing part 32 fits against the inner end of the detection port 13.

[0047] Understandably, the first sealing part 31 is mainly used to prevent water that may accidentally adhere to the detection terminal 21 from flowing onto the main control board 2, and the second sealing part 32 is mainly used to prevent water from entering the detection box 1 from the gap between the detection terminal 21 and the inner end of the detection port 13, thereby improving the sealing performance in all aspects.

[0048] For example, the sealing sleeve 3 is made of an elastic material, such as rubber. The first sealing portion 31 may have a U-shaped structure or a barrel-shaped structure with two adjacent openings. The second sealing portion 32 may have a loop-shaped structure or a U-shaped structure.

[0049] In some embodiments, such as Figure 2 As shown, the detection box 1 includes a detection bottom cover 11 and a detection top cover 12 disposed opposite to each other. The detection bottom cover 11 and the detection top cover 12 form a receiving cavity and together hold the main control board 2. The side of the detection bottom cover 11 and the side of the detection top cover 12 form a detection opening 13. The first sealing part 31 is provided with a sealing groove 311 on the side facing the detection top cover 12. At least a part of the detection top cover 12 is embedded in the sealing groove 311.

[0050] It should be noted that the detection bottom cover 11, the main control board 2, and the detection top cover 12 can be imagined to be set in a parallel state.

[0051] Understandably, since the detection terminal 21 is connected to the main control board 2, no additional sealing structure is needed on the side of the main control board 2 where the detection terminal 21 is connected. The side of the detection terminal 21 facing away from the main control board 2 is sealed with a sealing groove 311 to improve the sealing performance between the detection terminal 21 and the detection cover 12. Especially when the sealing sleeve 3 is made of an elastic material, the first sealing part 31 facing the detection cover 12 deforms to improve the tightness of the connection with the detection cover 12.

[0052] For example, the first sealing part 31 can adopt a U-shaped structure, with the openings on opposite sides of the U-shaped structure facing the main control board 2 and the detection cover 12, respectively. Alternatively, the first sealing part 31 can adopt a barrel-shaped structure with two adjacent openings, with the two openings facing the detection bottom cover 11 and the detection port 13, respectively. Correspondingly, the inner side of the detection cover 12 is provided with a corresponding structure embedded in the sealing groove 311.

[0053] In some embodiments, such as Figure 3 as well as Figure 4 As shown, the sealing groove 311 extends around the detection terminal 21.

[0054] Understandably, when the first sealing part 31 adopts a U-shaped structure, the sealing groove 311 extends in a U-shape to better seal between the detection terminal 21 and the detection cover 12. Correspondingly, the inner side of the detection cover 12 is provided with a U-shaped protrusion.

[0055] In some embodiments, such as Figure 3 as well as Figure 4As shown, the second sealing part 32 is provided with a limiting groove 321 on the side facing the detection bottom cover 11, and at least a portion of the detection bottom cover 11 is embedded in the limiting groove 321.

[0056] Understandably, the fit between the limiting groove 321 and the detection bottom cover 11 restricts the sealing sleeve 3 from disengaging from the detection terminal 21, thereby improving the installation reliability of the sealing sleeve 3.

[0057] In some embodiments, such as Figure 4 As shown, multiple detection terminals 21 and sealing sleeves 3 are provided in a one-to-one correspondence; or, multiple detection terminals 21 are provided, and sealing sleeves 3 are fitted onto multiple detection terminals 21, with the first sealing part 31 extending along the surface of the main control board 2 and surrounding multiple detection terminals 21.

[0058] Understandably, the detection device is usually equipped with multiple detection terminals 21 to detect different operating parameters of the air conditioner. Multiple sealing sleeves 3 can be used to seal and connect multiple detection terminals 21 one by one, or multiple adjacent detection terminals 21 can be connected by a single sealing sleeve 3.

[0059] For example, the main control board 2 has multiple detection terminals 21 on opposite sides, and each of the multiple detection terminals 21 on each side is fitted with a sealing sleeve 3.

[0060] In some embodiments, such as Figure 5 as well as Figure 6 As shown, the detection box 1 is provided with an installation port 14. Inside the installation port 14, there is a button 15 and two connecting arms 16 connected to opposite sides of the button 15. The two connecting arms 16 extend spirally in the same direction and are respectively connected to opposite sidewalls of the installation port 14. The two connecting arms 16 are located in the same plane.

[0061] It should be noted that "the two connecting arms 16 extend spirally in the same direction" means that the two connecting arms 16 extend around the button 15 in a clockwise or counterclockwise direction, which is approximately a spiral line, and the spiral line is a planar spiral line. The two ends of each connecting arm 16 are respectively connected to the button 15 and the side wall of the mounting port 14.

[0062] It is understandable that when button 15 is pressed, the two connecting arms 16 can undergo adaptive deformation. After the pressing force is removed, the stress of the two connecting arms 16 causes button 15 to return to its original position. Furthermore, before button 15 is pressed, the two connecting arms 16 are located on the same plane, which can save installation space of detection box 1 while realizing button 15 reset.

[0063] In some embodiments, such as Figure 7 As shown, the test box 1 is provided with a waterproof membrane 17, which covers the installation port 14. The waterproof membrane 17 is elastic.

[0064] It should be noted that the waterproof membrane 17 can be made of known elastic materials, such as plastic.

[0065] Understandably, the elastic waterproof membrane 17 not only prevents water from entering the detection box 1 through the installation port 14, but also prevents the button 15 from being punctured after repeated pressing.

[0066] For example, the waterproof membrane 17 can be made of a transparent and elastic material, so that the inspector can clearly see the position of the button 15 and it is not easy to puncture it after repeated pressing of the button 15.

[0067] In some embodiments, such as Figure 2 As shown, the detection box 1 is provided with an indicator light slot, and an indicator light 18 is provided in the indicator light slot. The waterproof membrane 17 is made of transparent material and covers the indicator light slot.

[0068] Understandably, the waterproof membrane 17 can be made of a transparent material so that the inspectors can clearly see the indicator light 18.

[0069] In some embodiments, such as Figure 8 as well as Figure 9 As shown, the detection device also includes a protective sleeve 4, which surrounds the periphery of the detection box 1. The protective sleeve 4 is provided with an avoidance window 41, which exposes the detection port 13.

[0070] It is understood that the periphery of the test box 1 refers to the side of the test box 1 and the corners between adjacent side edges. The protective sleeve 4 can improve the sealing between the test bottom cover 11 and the test top cover 12, preventing moisture from entering the test box 1 through the gap between the test bottom cover 11 and the test top cover 12, thus affecting the test results.

[0071] For example, the protective sleeve 4 is made of an elastic material, such as rubber.

[0072] In some embodiments, such as Figure 9 As shown, a protective plate 42 is connected to the side wall of the avoidance window 41. The protective plate 42 covers the detection terminal 21. The side of the protective plate 42 is separated from the side wall of the avoidance window 41. The protective plate 42 is configured to elastically deform and open to expose the detection terminal 21.

[0073] Understandably, when testing is required, the testing personnel manually pry open and press down the protective sheet 42 to continuously expose the testing terminal 21 for testing. After the testing is completed, the protective sheet 42 is removed by hand, and the protective sheet 42 covers the testing terminal 21 again under the action of elastic restoring force, which plays a role in waterproofing and protection.

[0074] For example, the outer side of the protective sheet 42 is provided with a rib so that the protective sheet 42 can be manually lifted to expose the detection terminal 21.
