Description

Technical Field

[0001] This utility model belongs to the technical field of aerosol generating devices, and particularly relates to an anti-clogging aerosol generating device with a detachable filter. Background Technology

[0002] Aerosol generating devices are equipment that convert liquid or solid substances into tiny particles (i.e., aerosols) suspended in a gas through mechanical, physical, or chemical means. They commonly employ various technical principles such as mechanical atomization, electro-spraying, and pyrolysis. For example, some devices use a compressor in conjunction with a two-phase nozzle to create negative pressure, causing the substance and airflow to converge and form bubbles. These bubbles burst, releasing droplet aerosols. Other devices adjust the atomization flow rate to change the particle concentration, generating aerosols with particle sizes ranging from nanometers to micrometers and controllable concentrations. These devices are often compact and portable, with some supporting remote control or battery power. They are widely used in filter integrity testing, particle measurement instrument calibration, cleanroom acceptance testing, wind tunnel tracing studies, and experimental and testing work in environmental science, medicine, and other fields.

[0003] This device uses a compressor and a two-phase nozzle to create negative pressure, causing the substance and airflow to converge and form bubbles. After the bubbles burst, they release aerosol droplets. Therefore, air needs to be drawn from the outside through pipelines and compressed. To ensure the purity and stability of the aerosol, the intake air needs to be filtered. The current aerosol generating devices have relatively simple filtration structures. Most impurities in the air are solid dust particles. After a period of use, the current filtration structure is easily clogged by these solid particles. At this time, the filter screen in the filtration structure needs to be disassembled and cleaned, which is inconvenient. Utility Model Content

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution: an anti-clogging aerosol generating device with a detachable filter screen, including a device body 1 and a filtering mechanism 3. The top of the device body 1 is connected to an air inlet pipe 2, and the filtering mechanism 3 is located at the rear end of the air inlet pipe 2. The filter mechanism 3 includes a connecting pipe 31 fixedly connected to and communicating with the rear end of the air inlet pipe 2. The rear end of the connecting pipe 31 is connected to a connecting hose 32. The rear end of the connecting hose 32 is connected to a front cylinder 33 with both ends open. A rear cylinder 34 is detachably installed at the rear of the front cylinder 33. An extension air pipe 35 is connected to the rear end of the rear cylinder 34. A filter screen structure 312 is detachably installed inside the front cylinder 33. A backflush pipe 37 is connected between the front cylinder 33 and the extension air pipe 35. A drain pipe 38 is connected to the bottom end of the rear cylinder 34. A first valve 39 is provided on the backflush pipe 37. A second valve 310 and a third valve 311 are respectively provided on the extension air pipe 35 located in front of the backflush pipe 37 and on the connecting pipe 31.

[0016] In this embodiment, during operation, an external air compressor supplies outside air into the main body 1 of the device. During this process, the outside air is filtered by the filter mechanism 3. Under normal operating conditions, the first valve 39 is closed, while the second valve 310 and the third valve 311 remain open. Outside air sequentially passes through the extension pipe 35, the rear cylinder 34, the front cylinder 33, the connecting hose 32, and the connecting pipe 31 before entering the air inlet pipe 2 and then the main body 1. The filter structure 312 inside the front cylinder 33 filters the air. After the mesh structure 312 becomes clogged after a period of use, the second valve 310 and the third valve 311 can be closed and the first valve 39 can be opened. After entering the extension air pipe 35, the outside air will directly enter the interior of the backwash pipe 37, and then enter the front cylinder 33 from the front of the filter structure 312 and pass through the filter structure 312 in the reverse direction, washing away the dust and impurities attached to it and discharging them through the drain pipe 38. This cleans the filter structure 312, eliminating the need for repeated disassembly and separate cleaning of the filter structure 312, making the equipment more convenient to use.

[0017] Furthermore, a sealing cap is detachably installed at the bottom of the drain pipe 38, and the outer surface of the sealing cap is provided with anti-slip texture.

[0018] In this embodiment, during normal operation, the sealing cap is installed at the bottom of the drain pipe 38, while during backwashing, the sealing cap needs to be removed.

[0019] Furthermore, the rear part of the inner surface of the front cylinder 33 is provided with an external thread, and the front end of the outer surface of the rear cylinder 34 is provided with an internal thread that matches the external thread. The rear cylinder 34 is detachably installed at the rear end of the front cylinder 33 through the internal thread.

[0020] In this embodiment, the front cylinder 33 and the rear cylinder 34 are connected by a threaded connection. The number of threads used for connection between the two is small, and the backflushing pipe 37 is also a soft pipe. Therefore, the backflushing pipe 37 will not affect the disassembly and installation. If the filter structure 312 still needs to be replaced after a long period of use, the front cylinder 33 and the rear cylinder 34 can be disassembled to replace the filter structure 312.

[0021] Furthermore, the filter structure 312 includes an outer retaining ring, a filter plate is fixedly connected inside the outer retaining ring, a sealing ring 313 is provided on the outer surface of the outer retaining ring, and multiple springs are provided on the outer surface of the outer retaining ring. The filter structure 312 is detachably installed inside the front cylinder 33 through the multiple springs.

[0022] In this embodiment, the filter structure 312 performs filtration through the filter plate therein, and the sealing ring 313 on its outer retaining ring plays a sealing role, ensuring the overall filtration capacity of the filter mechanism 3.

[0023] Furthermore, the rear end of the extended trachea 35 is connected to a connecting tube 36.

[0024] A lifting handle 4 is fixedly connected to the upper surface of the main body 1, and multiple anti-slip pads 6 are fixedly connected to the bottom of the main body 1. Heat dissipation grooves 5 are opened on the side wall surface of the main body 1.

[0025] In this embodiment, the specific specifications of the connecting pipe 36 can be selected according to the actual situation of the external compressor, so as to ensure that it is tightly connected to the air outlet of the compressor.

[0026] The lifting handle 4 makes it easy for people to carry the device, while the heat dissipation grooves 5 on the side wall have a heat dissipation effect, so that the internal structure of the device will not overheat and be damaged during operation. The anti-slip pads 6 provide anti-slip support, making the device more stable during operation.

[0027] The working principle and usage process of this utility model are as follows: After installation, when the device is in operation, an external air compressor sends outside air into the main body 1 of the equipment. During this process, the outside air is filtered by the filter mechanism 3. Under normal operating conditions, the first valve 39 is closed, while the second valve 310 and the third valve 311 remain open. The outside air sequentially passes through the extension air pipe 35, the rear cylinder 34, the front cylinder 33, the connecting hose 32, and the connecting pipe 31 into the air inlet pipe 2 before entering the main body 1 of the equipment. The filter structure 312 inside the front cylinder 33 filters the air... The air is filtered, and when the filter structure 312 becomes clogged after a period of use, the second valve 310 and the third valve 311 can be closed and the first valve 39 can be opened. After entering the extension air pipe 35, the outside air will directly enter the interior of the backwash pipe 37, and then enter the front cylinder 33 from the front of the filter structure 312 and pass through the filter structure 312 in the reverse direction, washing away the dust and impurities attached to it and discharging them through the drain pipe 38. This cleans the filter structure 312, eliminating the need for repeated disassembly and separate cleaning of the filter structure 312, making the equipment more convenient to use.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
