Technical Field

[0002] Atmospheric air bag samplers are widely used in atmospheric environment monitoring, health and epidemic prevention, labor protection, scientific research, teaching and other units, and can also be used in conjunction with relevant instruments.

This method will cause the coil to continue to heat up, consume a lot of power, and cause the instrument to heat up seriously. Utility Model Content

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The present embodiment is about an air bag atmospheric sampler, which includes a housing 1 and a main control panel 2 located at the upper opening of the housing 1, and the two together form an inner cavity 3. A heat dissipation hole 4 is opened on the housing 1, and a plurality of three-way solenoid valves 8 and a plurality of single-way solenoid valves 9 are arranged in the inner cavity 3. Each single-way solenoid valve 9 is connected to a rubber pipe 12, and the free end of the rubber pipe 12 is connected to the main control panel 2 through a vacuum box air nozzle 13. The coil side of the single-way solenoid valve 9 is installed with a magnet 14 through a magnet fixing plate 15.

[0020] Based on the above structure, the size of the magnet 14 is determined according to the size and parameters of the single-way solenoid valve 9. Therefore, in actual use, it is only necessary to briefly power the three-way solenoid valve 8 and the single-way solenoid valve 9, and the magnet 14 is used to maintain operation for the rest of the time. This greatly reduces the power consumption of this embodiment in operating conditions and reduces the heat generation problem in the casing 1.

[0021] Preferably, a lithium battery pack 10 and an air pump 11 are also installed in the inner cavity 3. Figure 1As shown, the lithium battery pack 10 is installed on the bottom inner wall of the housing 1 , and the air pump 11 is located on one side of the lithium battery pack 10 and close to the three-way solenoid valve 8 .

[0022] Preferably, the three-way solenoid valve 8 and the one-way solenoid valve 9 are arranged separately, and multiple one-way solenoid valves 9 are installed at intervals from each other. By limiting the installation position and spacing them from each other, heat accumulation is prevented, which is beneficial to heat dissipation. The heat accumulation problem in the inner cavity 3 is reduced by optimizing the installation structure.

[0023] Preferably, the multiple rubber pipes 12 are gathered and arranged on the same side wall inner wall of the casing 1, and the multiple vacuum box air nozzles 13 corresponding to the multiple rubber pipes 12 are arranged in a line on the main control panel 2, making the internal structure more concise.

[0024] In this embodiment, a control circuit is also integrated in the main control panel 2. The control circuit is not a technical content that needs to be protected in this application, so it will not be described in detail.

[0025] Preferably, handles 7 are installed on both sides of the main control panel 2. It is easy to understand that the handles 7 are used for carrying and transferring the placement position of this embodiment.

[0026] A pipeline telescopic bracket 6 is installed on one side of the connection position between the casing 1 and the main control panel 2 through the telescopic bracket seat 5. The pipeline telescopic bracket 6 extends vertically upward and changes its own telescopic height to change the sampling height. During actual sampling, the tetrafluoroethylene pipeline of the air bag can adjust the sampling height through the pipeline telescopic bracket 6.

[0027] In this way, the air bag atmospheric sampler disclosed in the utility model has an optimized structural design, and the heat generating equipment is dispersed to prevent the accumulation of heat. By adding a magnet to the single-way solenoid valve, the working condition of the conventional solenoid valve, which requires full power supply during use, is changed. The solenoid valve can be switched by only briefly energizing it, thereby fundamentally solving the problem of continuous heat generation of the coil during the power-on process of the conventional solenoid valve.

[0028] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
