[0002] In existing automatic sample preparation equipment, in order to prevent materials from clogging the equipment or remaining inside the equipment during the sample preparation process, a pneumatic vibrator and an air blowing device are usually used in combination to clean the material inside the equipment.

[0003] Currently, the pneumatic vibrator and air blowing device used to clean materials inside the equipment are usually independent of each other, that is, the pneumatic vibrator and air blowing device are connected to the air supply equipment through different ventilation pipes. This setting method increases the number of parts and pipes in the system. Moreover, if a pneumatic vibrator or air blowing device needs to be added during the subsequent equipment improvement, it is necessary to add ventilation pipes and valves and modify the PLC program, making the internal structure of the system and the system maintenance extremely complicated.

[0004] At the same time, because the vibration frequency and amplitude of the pneumatic vibrator are controlled by adjusting the gas pressure and flow rate, connecting the pneumatic vibrator and the air blowing device through different ventilation pipes may lead to insufficient air pressure in the pneumatic vibrator or inconvenient adjustment, resulting in the frequency and amplitude of the pneumatic vibrator not meeting the required use, thereby affecting the material cleaning effect. Therefore, inventing a pneumatic cleaning system with a simple structure and good cleaning effect is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0031] In order to enable those skilled in the art to which this application belongs to understand this application more clearly, the technical solution of this application is described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0032] In the embodiments of this application, Figure 1 As shown, the pneumatic cleaning system includes a pneumatic vibrator 1, an air blowing device 2 and an air compressor 3; wherein,

[0033] The air outlet of the air compressor 3 is connected to the air inlet of the pneumatic vibrator 1, and the air inlet of the air blowing device 2 is connected to the air outlet of the pneumatic vibrator 1, so that the ventilation pipelines of the pneumatic vibrator 1 and the air blowing device 2 are integrated into one;

[0034] The air compressor 3 can provide the pneumatic vibrator 1 and the air blowing device 2 with the compressed gas required for their operation;

[0035] The action end of the pneumatic vibrator 1 acts on the equipment to be cleaned so as to transmit the vibration force to the equipment to be cleaned and loosen the accumulated materials attached to the equipment to be cleaned;

[0036] The air outlet end of the air blowing device 2 is directed toward the part to be cleaned of the equipment to be cleaned, so as to blow away the loosened accumulated materials and separate the accumulated materials from the equipment to be cleaned, thereby cleaning the equipment to be cleaned.

[0037] In this embodiment, the equipment to be cleaned is an automatic sample preparation equipment; when it is necessary to clean the accumulated materials in the automatic sample preparation equipment, the staff can start the pneumatic vibrator 1 to start the vibration. The action end of the pneumatic vibrator 1 contacts the automatic sample preparation equipment. As the vibration proceeds, the accumulated materials attached to the inner wall of the automatic sample preparation equipment or the surface of the material will loosen and fall off, and then be blown away from the automatic sample preparation equipment under the action of the compressed gas ejected by the air blowing device 2, thereby achieving thorough cleaning of the automatic sample preparation equipment.

[0038] The pneumatic cleaning system integrates the ventilation pipes of the pneumatic vibrator 1 and the air blowing device 2 into one, reducing the number of ventilation pipes, reducing the complexity of the equipment and the manufacturing cost. At the same time, the air blowing device 2 uses the exhaust gas of the pneumatic vibrator 1 to work, and there will be no situation where the frequency and amplitude of the pneumatic vibrator 1 do not meet the use requirements due to insufficient air pressure.

[0039] In some embodiments, the air outlet of the air compressor 3 is connected to the air inlet of the pneumatic vibrator 1 via a first air pressure pipe 41, and the air outlet of the pneumatic vibrator 1 is connected to the air inlet of the air blowing device 2 via a second air pressure pipe 42. Preferably, the first air pressure pipe 41 and the second air pressure pipe 42 are both hoses, so that the placement or use position of the pneumatic vibrator 1 and the air blowing device 2 are not restricted by the first air pressure pipe 41 and the second air pressure pipe 42, and can be placed or moved at will, thereby making the use of the pneumatic cleaning system more convenient.

[0040] It is worth noting that in the prior art, the pneumatic vibrator 1 and the air blowing device 2 are two independent devices. If the number of the pneumatic vibrator 1 and the air blowing device 2 needs to be increased, it is necessary to add ventilation pipes and valves and modify the system program, which makes the entire operation process extremely complicated.

[0041] The present application provides a quick connector 5 at the outlet of the air compressor 3, see Figure 1 The air outlet of the air compressor 3 is connected to the air inlet of the first air pressure tube 41 through a quick connector 5, so that the connection and removal of the first air pressure tube 41 and the air compressor 3 are more convenient. The staff can appropriately increase the number of pneumatic vibrators 1 and air blowing devices 2 according to the needs and the power of the air compressor 3 to meet the work requirements. Preferably, the number of the above-mentioned pneumatic vibrators 1 and air blowing devices 2 is multiple groups, and the air inlet ends of the multiple groups of pneumatic vibrators 1 are connected to the air outlet ends of the air compressor 3, and the air inlet ends of the multiple groups of air blowing devices 2 are connected to the air outlet ends of the multiple groups of pneumatic vibrators 1 in a one-to-one correspondence.

[0042] In some embodiments, the air blowing device 2 includes an air nozzle, and the air outlet of the pneumatic vibrator 1 is connected to the air inlet of the air nozzle;

[0043] The staff can fix the position and direction of the air nozzle through the fixing device (bracket) to clean the accumulated materials on the inner wall or material surface of the automatic sample preparation equipment, or adjust the direction of the compressed gas sprayed by the air blowing device 2 by holding the air nozzle to better complete the cleaning work of the accumulated materials.

[0044] In some embodiments, the air blowing device 2 includes a spray gun, and the air outlet of the pneumatic vibrator 1 is connected to the air inlet of the spray gun;

[0045] The staff can hold the spray gun, determine the spray direction, and then press the trigger on the spray gun to open the handheld spray gun and spray compressed gas toward the inner wall of the automatic sample preparation equipment or the surface of the material to complete the cleaning of the accumulated material.

[0046] In some embodiments, the air outlet of the air compressor 3 is provided with an on-off valve 6, and the air outlet of the air compressor 3 is connected to the air inlet of the pneumatic vibrator 1 through the on-off valve 6. The connection and disconnection between the air compressor 3 and the pneumatic vibrator 1 are achieved by controlling the opening / closing of the on-off valve 6, so that the operation of the pneumatic cleaning system is more convenient.

[0047] When the pneumatic vibrator 1 or the air blowing device 2 fails to work properly, the connection between the air compressor 3 and the pneumatic vibrator 1 can be disconnected by closing the on-off valve 6 to facilitate maintenance of the pneumatic vibrator 1 and the air blowing device 2.

[0048] In some embodiments, the pneumatic cleaning system further comprises a controller 7; see Figure 1 ,in,

[0049] The opening and closing valve 6 is a solenoid valve;

[0050] The controller 7 is connected to the on-off valve 6, the air compressor 3 and the pneumatic vibrator 1 by signal;

[0051] When the pneumatic cleaning system starts working, the controller 7 will first send an air pressure signal to the pneumatic vibrator 1. After receiving the air pressure signal, the pneumatic vibrator 1 will first vibrate to shake off the residual accumulated materials attached to the inner wall of the automatic sample preparation equipment.

[0052] At the same time, the exhaust gas generated by the outlet end of the pneumatic vibrator 1 enters the air blowing device 2. The compressed gas blown out by the air blowing device 2 can further blow the residual accumulated material away from the automatic sample preparation equipment to achieve thorough cleaning. Preferably, the controller 7 is a PLC controller.

[0053] Through the above embodiments, the present application has the following beneficial effects or advantages:

[0054] 1) The air inlet end of the air blowing device 2 in the pneumatic cleaning system is connected to the air outlet end of the air blowing vibrator, so that the ventilation pipeline of the pneumatic vibrator 1 and the air blowing device 2 are integrated into one, which not only simplifies the layout of the ventilation pipeline of the pneumatic cleaning system, but also reduces the manufacturing cost and maintenance difficulty of the pneumatic cleaning system. The air blowing device 2 uses the exhaust gas of the pneumatic vibrator 1 to work, and there will be no situation where the frequency and amplitude of the pneumatic vibrator 1 do not meet the use requirements due to insufficient air pressure, thereby ensuring the cleaning effect of the pneumatic cleaning system.

[0055] 2) The integrated design of the ventilation pipeline of the pneumatic vibrator 1 and the air blowing device 2 in the pneumatic cleaning system makes the adjustment of the air pressure more convenient.

[0056] 3) The air blowing device 2 in the pneumatic cleaning system rationally utilizes the exhaust gas discharged by the pneumatic vibrator 1, and changes the original parallel connection mode to a series connection mode, which effectively reduces the energy consumption of the pneumatic cleaning system.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.

[0058] Obviously, those skilled in the art may make various changes and modifications to this application without departing from the spirit and scope of this application.
