[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0021] See also Figure 1-5 This embodiment provides a dustproof test device, including a box 1. The box 1 is a dustproof test box with a reference model of GSC-500, and a test cavity is provided on the end surface of the box 1. A door for closing the test cavity is rotatably installed at the end surface of the box 1 where the test cavity is provided, and a placement rack 11 is installed at the bottom of the test cavity, and the placement rack 11 is used to support the equipment used for the test.

[0022] like Figure 3 As shown, a sliding cavity is provided on the side wall of the box body 1, an exhaust port is provided between the test cavity and the sliding cavity of the box body 1, an air inlet is provided on the outer side wall of the box body 1, and the air inlet is also interconnected with the sliding cavity, a fan 3 is fixedly connected to the side wall of the box body 1, and the reference model of the fan 3 is a blower of CX-125A, an air outlet is provided below the fan 3, an air duct 31 is fixedly connected between the air outlet of the fan 3 and the air inlet of the box body 1, and the fan 3 is interconnected with the sliding cavity of the box body 1 through the air duct 31.

[0023] Three dust boxes 2 are slidably installed in the sliding cavity of the box 1. Of course, it is not limited to three. Multiple dust boxes 2 can be set according to the test needs, and different test dusts can be injected into different dust boxes 2. The exhaust port and air inlet opened in the box 1 are located on the same horizontal plane, and the exhaust port and air inlet are tilted, and one end of the air inlet is tilted downward toward the sliding cavity of the box 1. The sliding cavity of the box 1 can be divided into three layers. The sliding cavity located above the exhaust port and the air inlet is divided into a storage layer, and the sliding cavity located below the exhaust port and the air inlet is divided into a placement layer. The air guide layer is located on the same horizontal line as the exhaust port and the air inlet. After the fan 3 is started, strong wind enters the air inlet through the air guide pipe 31, and the air inlet is tilted downward toward the sliding cavity, so that the strong wind blows into the placement layer of the sliding cavity, stirring the dust in the dust box 2 at the top of the placement layer to float, and then the floating dust will be discharged from the exhaust port to the test cavity of the box 1 to contact the test equipment.

[0024] A control mechanism 4 for controlling the upward and downward movement of the dust box 2 is installed in the box body 1. The control mechanism 4 includes a first telescopic rod 41, a second telescopic rod 42 and a sliding tube 43, wherein the sliding tube 43 is fixedly inserted in the dust box 2, and the sliding tubes 43 in multiple dust boxes 2 are aligned vertically. The first telescopic rod 41 is fixedly installed in the side wall of the box body 1, and the first telescopic rod 41 is configured as a hydraulic rod. The output rod of the first telescopic rod 41 is upward, and the output rod of the first telescopic rod 41 slides through the bottom sliding tube 43 and the middle sliding tube 43. The output rod of the first telescopic rod 41 is fixedly inserted in the top sliding tube 43 at the top. The second telescopic rod 42 is configured as an electric telescopic rod. The second telescopic rod 42 is fixedly installed in the output rod of the first telescopic rod 41. After the second telescopic rod 42 is controlled to extend, the output rod of the second telescopic rod 42 extends from the outer side wall of the output rod of the first telescopic rod 41. The inner side wall of the middle sliding tube 43 is provided with a card slot matching the output rod of the second telescopic rod 42. Figure 3 As shown, the circuit for controlling the extension and retraction of the second telescopic rod 42 passes through the first telescopic rod 41 and the uppermost sliding tube 43 and enters the box body 1 , and is connected to the control board in the box body 1 .

[0025] Taking the case where there are three dust boxes 2, when the dust in the top dust box 2 is blown out, there is no need to use the control mechanism 4. When the dust in the middle dust box 2 needs to be tested, the first telescopic rod 41 is extended, and the output rod of the first telescopic rod 41 drives the top sliding tube 43 to move upward, which can drive the top dust box 2 to move to the storage layer of the sliding cavity. At this time, strong wind can be blown into the middle dust box 2, stirring the dust in the middle dust box 2 and blowing it out from the exhaust port to the test cavity of the box body 1. When the dust in the lowermost dust box 2 needs to be tested, the first telescopic rod 41 is retracted to reset it, and the second telescopic rod 42 is started to be extended. The output rod of the second telescopic rod 42 extends from the outer side wall of the output rod of the first telescopic rod 41, and the extended end of the output rod of the second telescopic rod 42 is engaged in the slot of the middle sliding tube 43. At this time, the first telescopic rod 41 is controlled to extend, and the uppermost sliding tube 43 and the middle sliding tube 43 can be driven to move synchronously through the second telescopic rod 42, that is, the uppermost dust box 2 and the middle dust box 2 are driven to move into the storage slot of the sliding cavity. At this time, the fan 3 is started, and strong wind can be blown into the lowermost dust box 2, stirring the dust in the middle dust box 2 and blowing it out from the exhaust port to the test cavity of the box body 1.

[0026] The sliding tube 43 is located in the middle part of the dust box 2, which is located at the center of gravity of the dust box 2, thereby stabilizing the movement of the dust box 2. At the same time, when strong wind blows into the dust box 2, the sliding tube 43 can effectively block and disperse part of the wind force. This blocking brings about a change in wind direction, causing the airflow to form multiple branches inside the dust box 2. This branching effect helps to stir the dust in the dust box 2 more evenly, so that the dust can be fully blown out into the test chamber of the box body 1.

[0027] Different dust boxes 2 are filled with different dusts. In order to add dust to the dust box 2, the air duct 31 is connected to a feed pipe 32 away from the side wall of the box body 1. Figure 5 As shown, taking three dust boxes 2 as an example, when it is necessary to inject dust into the top dust box 2, dust is injected into the feed pipe 32, and the lower end of the inner part of the air guide pipe 31 is set as an inclined surface, and the dust injected into the feed pipe 32 slides into the top dust box 2 due to its own gravity. When it is necessary to inject dust into the middle dust box 2, the top dust box 2 is moved by the control mechanism 4, and at this time, the dust injected into the feed pipe 32 can fall into the middle dust box 2. The same is true for the bottom dust box 2, and the top and middle dust boxes 2 can be moved synchronously by the control mechanism 4.

[0028] When the fan 3 is started, in order to prevent wind from being discharged from the feed pipe 32 , the feed pipe 32 is threadedly connected with a cover 33 when not in use, and the feed pipe 32 is closed by the cover 33 .

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
