DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0025] The utility model provides technical schemes: as Figure 2 and Figure 3 Indicated, in the embodiment, an aerosol generator for animal experiments, including generator body 1, the outside installation of generator body 1 has feeding assembly 3, and feeding assembly 3 includes the limit rod 302 fixedly connected on the one side outer wall of generator body 1, the connecting seat 303 is slidably covered outside limit rod 302, and the horizontal setting silk rod 301 is rotatably connected in the inside of limit rod 302 through bearing, the connecting seat 303 is screwedly covered outside silk rod 301, the motor is fixedly installed on the one end outer package of limit rod 302, and the output end of motor is coaxially fixed with the one end of silk rod 301, the inside of connecting seat 303 is provided with two joints, and one sample bottle 304 is screwedly connected in the inside of two joints, and the extraction pipe is arranged in the bottom of two joints of connecting seat 303, and the extraction pipe extends to the bottom position of sample bottle 304.

[0026] As Figure 2 and Figure 3 Indicated, the outside installation of generator body 1 has extraction assembly 4, and extraction assembly 4 includes the support frame 401 fixedly connected on the one side outer wall top of generator body 1, and the vertical setting sliding rod 402 is fixedly connected in the inside of support frame 401, and the extraction head 403 that is adapted to the joint of connecting seat 303 is slidably covered outside sliding rod 402, and the extraction head 403 one side outer wall is pasted with the one side inner wall of support frame 401.

[0027] Sliding rod 402 is covered with spring one 404, and spring one 404 is at the top of extraction head 403, and control knob 406 is fixedly installed on the one side outer wall of generator body 1, and control knob 406 is electrically connected with motor through wire, and the extension plate that is corresponding with the position of control knob 406 is arranged outside extraction head 403.

[0028] After the sample in a sample vial 304 has been extracted, the extraction head 403 is pulled upwards. The spring 404 at its top is compressed and shortened, and the rubber head 405 at its bottom disengages from the interface of the connecting seat 303. Then, the extraction head 403 presses the control button 406, which starts the motor. The lead screw 301 connected to its output end begins to rotate. The connecting seat 303, which is sleeved outside the limit frame 302, is driven by the lead screw 301 to move horizontally. The interface connected to another sample vial 304 moves to directly below the extraction head 403. Then, the restriction on the extraction head 403 is released, and the spring 404 pushes the extraction head 403 to engage with the interface of the next sample vial 304, allowing it to continue to be used while ensuring a tight connection between the two.

[0029] like Figure 2 and Figure 4 As shown, a clearance groove is provided on the top of the generator body 1, and a control panel 2 adapted to the generator body 1 is placed inside the clearance groove. The same support component 5 is installed between the generator body 1 and the control panel 2.

[0030] The support assembly 5 includes two support frames 502 fixedly connected to the outer walls of both ends of the control panel 2. A limiting seat 501 is fixedly connected to the outer walls of both ends of the generator body 1. The two support frames 502 are slidably inserted into the two limiting seats 501 respectively. Two telescopic rods 503 are fixedly connected to one end of the outer wall of one limiting seat 501. The same positioning rod 505 is fixedly connected to one end of the two telescopic rods 503. Several insertion holes 506 adapted to the positioning rod 505 are opened on one end of the outer wall of one support frame 502. Two springs 504 are fixedly connected between the positioning rod 505 and the limiting seat 501.

[0031] If the location lacks support components, and the generator body 1 is too low to be convenient to use, pull the positioning rod 505 to one side. The spring 504 connected to it will be stretched and lengthened. The positioning rod 505 will disengage from the socket 506 along the limit seat 501, and the support frame 502 will no longer be restricted. Then, pull the control panel 2 upward. After reaching the appropriate position, release the restriction of the positioning rod 505. The spring 504 will drive the positioning rod 505 to be inserted into the socket 506 at the corresponding position. The support frame 502 and the control panel 2 will also be fixed, making it more convenient to use.

[0032] like Figure 1 and Figure 2 As shown, the generator body 1 is equipped with a spray chamber, a centripetal inertial separator, and a gas circuit. The spray chamber includes components such as a spray can, nozzle, and suction pipe. The centripetal inertial separator is used to select the size of liquid particles to obtain aerosols within the required particle size range. The gas circuit includes spray gas path, drying gas path, outlet gas path, and carrier gas path, and is composed of components such as an inlet filter, flow regulating valve, pressure gauge, and flow meter.

[0033] As Figure 2 shown, the generator body 1 one side outer wall fixedly connected with two with the connecting seat 303 connector adapter baffle 305, can cover up unused connector, so that one of the connector is not used when not affected by the external environment.

[0034] As Figure 3 shown, the extraction head 403 bottom outer wall bonding has the round table type setting rubber head 405, the connecting seat 303 connector top is provided with the groove that adapts with rubber head 405, so that the butt joint of both is more closely, and is favorable to improve the airtightness of both.

[0035] The utility model provides a kind of aerosol generator for animal experiment, specific working principle is as follows:

[0036] When the device works, the external compressed air is connected to the device, the high-speed airflow passes through the nozzle, and the negative pressure is generated to suck the liquid in the spray can to the nozzle. Then, these liquids are broken or dispersed into countless tiny particles by high-speed airflow. After the sample in one sample bottle 304 is completely extracted, the extraction head 403 is pulled upwards, the spring 404 at the top is compressed and shortened, and the rubber head 405 at the bottom is separated from the interface of the connecting seat 303. Then, the extraction head 403 presses the control knob 406, the control knob 406 controls the motor to start, and the lead screw 301 connected to the output end starts to rotate. The connecting seat 303 outside the limiting frame 302 is driven by the lead screw 301 to translate, and the interface connected to the other sample bottle 304 moves directly below the extraction head 403. Then, the restriction on the extraction head 403 is released, and the spring 404 pushes the extraction head 403 to interface with the next sample bottle 304, so that the use can continue. If there is a lack of support in use, the height of the generator body 1 is low and inconvenient to use. The positioning rod 505 is pulled to one side, the spring 504 connected thereto is stretched and lengthened, the positioning rod 505 is separated from the insertion hole 506 along the limiting seat 501, the supporting frame 502 is no longer restricted, and then the control panel 2 is pulled upwards. After reaching the appropriate position, the restriction on the positioning rod 505 is released, the spring 504 drives the positioning rod 505 to be inserted into the insertion hole 506 at the corresponding position, and the supporting frame 502 and the control panel 2 are also fixed, so that the use is more convenient.

[0037] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
