[0002] Carbon monoxide gas is a colorless, odorless, non-irritating and poisonous gas that cannot be perceived by the five senses. It can inhibit the oxygen-carrying ability of the blood. In some indoor environments, a carbon monoxide alarm is required to detect carbon monoxide gas. Generally, a carbon monoxide alarm includes an upper cover, a circuit board and a lower cover. The upper cover and the lower cover enclose an installation cavity, and the circuit board is placed inside the installation cavity. A circulation hole is opened on the surface of the upper cover, and a carbon monoxide sensing module is arranged below the circulation hole on the circuit board. The carbon monoxide sensing module is used to detect carbon monoxide gas.

[0003] In the production of carbon monoxide alarms, it is necessary to test the carbon monoxide sensing module. After confirming that the carbon monoxide sensing module can detect carbon monoxide gas, the carbon monoxide sensing module is installed on the housing. Specifically, during the detection, a carbon monoxide sensing module is inserted into the inside of the detection box, carbon monoxide gas is introduced into the inside of the detection box, and the carbon monoxide sensing module is powered on to confirm whether the carbon monoxide sensing module can normally detect carbon monoxide.

[0004] However, the existing detection boxes detect the carbon monoxide sensing modules one by one, and the detection efficiency is not high. Summary of the Utility Model

[0030] A circuit board detection device according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0031] Refer to Figure 1 and Figure 2, a circuit board detection device according to an embodiment of the present invention includes a detection mechanism, a ventilation mechanism, and a blocking mechanism. The detection mechanism includes a box body 100, a test module 110 disposed inside the box body 100, and a clamping assembly detachably and electrically connected to the test module 110. The clamping assembly is used for clamping a plurality of circuit boards; the ventilation mechanism includes an air inlet passage 120 and a diffuser fan 130. The air inlet passage 120 is disposed at a corner of the box body 100, and carbon monoxide is introduced into the box body 100 through the air inlet passage 120. The diffuser fan 130 is disposed inside the box body 100, and an air storage cavity 140 is formed between the diffuser fan 130 and the corner of the box body 100. The air storage cavity 140 is communicated with the air inlet passage 120, and the diffuser fan 130 is used for transporting carbon monoxide from the air storage cavity 140 to the middle of the box body 100; the blocking mechanism is used for blocking the air inlet passage 120.

[0032] In some embodiments of the present invention, a flip cover 150 is hinged to the top of the box body 100. The flip cover 150 forms the top wall of the box body 100, and the air inlet passage 120 is disposed on the flip cover 150.

[0033] Therefore, the box body 100 can be opened through the flip cover 150. The circuit board is clamped in the clamping assembly. Then, the clamping assembly is placed inside the box body 100 for testing.

[0034] Moreover, since the air inlet passage 120 is disposed on the flip cover 150, carbon monoxide gas can flow from the top of the box body 100 downward, which helps the carbon monoxide gas to quickly diffuse to the surroundings of the box body 100.

[0035] In some embodiments of the present invention, referring to Figure 3 , an air support rod 160 is disposed between the box body 100 and the flip cover 150. One end of the air support rod 160 is hinged to the inner side wall of the box body 100, and the other end of the air support rod 160 is hinged to the bottom of the flip cover 150.

[0036] Therefore, during the opening process of the flip cover 150, the air support rod 160 is used to lift the flip cover 150 upward, eliminating the need for manual support of the flip cover 150, which greatly facilitates the testing operation.

[0037] In some embodiments of the present invention, a connecting plate 170 is disposed at the bottom of the flip cover 150, and the flip cover 150 is connected to the diffuser fan 130 through the connecting plate 170.

[0038] Therefore, during the opening process of the flip cover 150, the diffuser fan 130 rotates synchronously with the flip cover 150, so that the diffuser fan 130 is away from the internal space of the box body 100. Therefore, when the clamping assembly is placed inside the box body 100, the interference between the diffuser fan 130 and the clamping assembly is avoided, and the placement difficulty of the clamping assembly is reduced.

[0039] In some embodiments of the present invention, referring toFigure 1 The plugging mechanism includes a connecting frame 180, a first connecting rod 190, a second connecting rod 200 and a handle rod 210. The connecting frame 180 is arranged on the top of the flip cover 150. The connecting frame 180, the first connecting rod 190, the second connecting rod 200 and the handle rod 210 are hinged to form a four-bar clamping mechanism. A plugging head 220 is arranged on the first connecting rod 190, and the plugging head 220 is used to plug the air inlet channel 120.

[0040] Therefore, by shaking the handle rod 210, the four-bar clamping mechanism drives the plugging head 220 to plug the air inlet channel 120, which can prevent carbon monoxide gas from escaping from the inside of the box body 100 and ensure that there is sufficient carbon monoxide gas in the box body 100 to be detected by the circuit board.

[0041] Of course, when ventilating, shake the handle rod 210 to make the four-bar clamping mechanism drive the plugging head 220 to open the air inlet channel 120.

[0042] In some embodiments of the present invention, the flip cover 150 is provided with a hook 230, and the side wall of the box body 100 is provided with a buckle lock 240. The buckle lock 240 and the hook 230 can be buckled with each other.

[0043] Therefore, after the flip cover 150 is closed, the flip cover 150 can be locked on the box body 100 by the mutual buckling of the buckle lock 240 and the hook 230, which is beneficial to reducing the gap between the flip cover 150 and the box body 100 and reducing the leakage of carbon monoxide gas.

[0044] In some embodiments of the present invention, refer to Figure 1 and Figure 4 , a plurality of socket connectors 250 are arranged on the bottom wall inside the box body 100. The socket connectors 250 are electrically connected to the test module 110. The clamping assembly has a plug 260, and the plug 260 is inserted into the socket connector 250.

[0045] Therefore, by inserting the plug 260 into the socket connector 250, the clamping assembly and the test module 110 are electrically connected, and it is also convenient for the clamping assembly to be disassembled and assembled with the test module 110.

[0046] It can be understood that the clamping assembly is also electrically connected to the circuit board.

[0047] In some embodiments of the present invention, the clamping assembly has a hinged positioning plate 270 and a clamping plate 280. The positioning plate 270 is provided with a positioning groove, the positioning groove accommodates the circuit board, and the positioning plate 270 and the clamping plate 280 clamp and fix the circuit board.

[0048] Therefore, the clamp 280 can be flipped open and the circuit board can be placed in the positioning groove for positioning. Then, the clamp 280 is flipped so that the clamp 280 and the positioning plate 270 clamp the circuit board and fix it. Finally, the clamping assembly with the circuit board is electrically connected to the test module 110 for testing.

[0049] It is understandable that a buckle may be connected between the positioning plate 270 and the clamping plate 280 , and the clamping plate 280 may be quickly opened or locked using the buckle.

[0050] In some embodiments of the present invention, referring to Figure 4 A positioning assembly is provided inside the box 100 , and the positioning assembly has two first positioning blocks 290 . The two first positioning blocks 290 are arranged opposite to each other, and the positioning plate 270 and the clamping plate 280 placed upright are accommodated between the two first positioning blocks 290 .

[0051] Therefore, when the clamping assembly with the circuit board is placed between the two first positioning blocks 290, the two positioning plates 270 can ensure that the positioning plates 270 and the clamping plates 280 are in an upright state and prevent the circuit board from falling out of the positioning groove.

[0052] Therefore, this embodiment has the following effects:

[0053] 1. The present invention is provided with a box body 100, a test module 110 and a clamping assembly. The box body 100 has a large internal space and can accommodate multiple circuit boards. The multiple circuit boards are clamped and fixed by the clamping assembly. The test module 110 is started to enable the circuit boards of the clamping assembly to detect carbon monoxide gas. Multiple circuit boards can be tested at one time without having to test each circuit board one by one, thereby improving detection efficiency.

[0054] 2. The utility model provides an air intake channel 120 and an air dispersion fan 130, so that external carbon monoxide enters the air containing cavity 140 through the air intake channel 120, and the air dispersion fan 130 transports the carbon monoxide from the air containing cavity 140 to various positions inside the box body 100, so that each circuit board can quickly detect carbon monoxide gas, avoiding the situation where some circuit boards fail to detect carbon monoxide gas, ensuring that the detection time of each circuit board is consistent, thereby improving the detection efficiency.

[0055] 3. The utility model sets a blocking mechanism. When the carbon monoxide gas enters the air chamber 140 through the air inlet channel 120, in order to maintain a stable amount of carbon monoxide gas in the box 100, the air inlet channel 120 is blocked by the blocking mechanism, thereby preventing the carbon monoxide gas from escaping from the interior of the box 100 and ensuring that there is sufficient carbon monoxide gas in the box 100 to be detected by the circuit board.

[0056] In the description of this specification, the description with reference to terms such as "one embodiment, some embodiments, illustrative embodiments, examples, specific examples or some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model.

[0057] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings.
