Embodiment 1

Referring toFIGS.1-10, a generating device of simulating a particulate environment for an experimental animal includes an experimental chamber1, and an upper sealing device2is arranged on the upper side of the experimental chamber1. An excreta storage device3configured to store animal excreta is arranged in the interior adjacent to the middle of experimental chamber1, and an ultrasonic atomization device4is installed at the bottom adjacent to the center of experimental chamber1. The upper side of the ultrasonic atomization device4is connected to a guide device5for guiding particles.

The interior of the experimental chamber1is provided with a bottom air supply chamber11, a pulling chamber12, and an experimental animal placement chamber13in turn from bottom to top. Two sides of the experimental animal placement chamber13are fixedly connected to an air pipe14for inputting and outputting air, and a pulling port122is arranged on a side of the pulling chamber12.

The upper sealing device2includes an upper cover22with a rectangle chamber penetrating through the bottom. A connecting bar24is fixedly connected on a bottom side wall of the upper cover22, and a receiving bar18is fixedly connected on an outer side wall adjacent to the top of the experimental chamber1. The receiving bar18and the connecting bar24are attached to each other and connected by a screw.

The excreta storage device3includes a rectangular simulation warehouse31adapted to fit within the pulling port122, and the interior of the simulation warehouse31is provided with a storage chamber32penetrating through the upper side.

When the experimental chamber1, the upper sealing device2, and the excreta storage device3in the present embodiment are in use, an upper sealing plate21is flipped to be opened from an entrance23, and the experimental animal is put into the interior of the experimental animal placement chamber13through the entrance23so that the experimental animal can live in the designated simulation space. After the experimental animal is placed, the upper sealing plate21is flipped to cover entrance23so that the upper sealing device2and the experimental chamber1are sealed to ensure the separation of the experimental environment of the experimental animal from the external environment, thereby improving the accuracy of the experimental data. After the experimental animal excretes, the excreta of the animal falls into the excreta storage device3and is collected by the excreta storage device3, so that the excreta can be emptied out by moving the excreta storage device3when animal excreta fills the excreta storage device3, which ensures the normal operation of the experiment of simulating the particulate environment.

The guide device5includes an air seal cover51, and a micro fan configured to drive the movement of particles generated in the ultrasonic atomization device4is installed inside the air seal cover51. Air guide pipes52are symmetrical on the left and right and fixedly connected to a side wall of the air seal cover51. The bottom of the air seal cover51is connected to the interior adjacent to the bottom side of the bottom air supply chamber11by a screw. One end of the ultrasonic atomization device4is arranged inside the air seal cover51. One end of the air guide pipes52penetrates through the pulling chamber12and extends into the interior of the experimental animal placement chamber13.

When the guide device5in the present embodiment is in use, the ultrasonic atomization device4is turned on, and the cavitation effect generated in a liquid medium by ultrasonic waves in the ultrasonic atomization device4leads to the generation of microwaves, such that the solution particles placed in the ultrasonic atomization device4for the experiment are atomized. The atomized solution particles are driven into the air guide pipes52by the micro fan in the air seal cover51and follow the pipe of the air guide pipes52to flow into the experimental animal placement chamber13to change the environment of the experimental animal placement chamber13, thereby changing the content of particles in the experimental animal placement chamber13. When moving in the experimental animal placement chamber13, the experimental animal absorbs air having the particles from the experimental animal placement chamber13. In this way, the trouble of intravenous injection and nasal drip is avoided, the impact of the experiment due to environmental differences is reduced effectively, and the accuracy of body change data of the experimental animal is enhanced in the simulated environment so that the experimental animal has more research significance and value.

Further, the upper side of the excreta storage device3is provided with a baffle device6, and the baffle device6includes a baffle plate61. Each of the baffle plate61and the bottom of the experimental animal placement chamber13is provided with a plurality of falling holes62for emptying the animal excreta. The upper side of the baffle plate61is in contact with a bottom side wall of the experimental animal placement chamber13. An upper clamping port121is arranged at the pulling chamber12on the side of the experimental chamber1away from the pulling port122. One end of the baffle plate61is inserted into the upper clamping port121, and two sides of the baffle plate61are provided with side clamping slots63. Two sides of the interior of the pulling chamber12are fixed with clamping bars corresponding to the side clamping slots63, and the clamping bars are inserted into the side clamping slots63. The bottom side walls of the pulling chamber12are symmetrically fixed with pulling limit bars123on the left and right for limiting the simulation warehouse31. The bottom of the simulation warehouse31is symmetrically provided with limit slots adapted to cooperate with the pulling limit bars123on the left and right, and the pulling limit bars123are inserted into the limit slots. When the excreta storage device3needs to be emptied of the animal excreta, the baffle plate61is pulled to be interlaced with the falling holes62at the bottom of the experimental animal placement chamber13, so that the baffle plate61seals the bottom of the experimental animal placement chamber13. In this way, the air in the experimental animal placement chamber13is prevented from entering the pulling chamber12through the falling holes62, and the external air is also prevented from entering the experimental animal placement chamber13through the pulling port122, thereby reducing the damage to the internal air tightness of the device.

Specifically, an extension pipe53is fixedly connected adjacent to the middle of two air guide pipes52, and one end of the extension pipe53is fixedly connected to an air emission ball54. A plurality of air emission holes55are arranged in the air guide pipes52and the air emission ball54. Through the air emission holes55on the air emission ball54and the air guide pipes52, the air is emitted into the experimental animal placement chamber13, so that the experimental environment in the experimental animal placement chamber13meets the requirements to facilitate the running of the experiment.

In addition, a side wall of the experimental animal placement chamber13is provided with an installation port15, and a TSI™ detector (particle detector)7penetrating through the installation port15is installed on a side of the experimental animal placement chamber13.

A food bucket9configured to hold food and water for the animal is slidably connected between the diet fixing plates17. The food bucket9is arranged in the experimental animal placement chamber13to feed the experimental animal, thereby ensuring the normal life of the experimental animal. Moreover, the sealing rubber baffle is arranged on the feeding port171, so that after the food and water are placed into the food bucket9, it is convenient to seal the feeding port171, while it is convenient to control the diet conditions of the rat and reduce the damage to the internal air tightness of the device. In addition, the thermometer, the hygrometer, and the TSI™ detector (particle detector)7are arranged to ensure the stability of the simulated environment.

Further, the upper side of the upper cover22is provided with the entrance23, and the entrance23is hinged with the upper sealing plate21configured to seal the entrance23. Each of the left and right sides of the interior of the upper cover22is provided with an ultraviolet lamp for sterilization and a lighting tube for illumination. The ultraviolet lamp is arranged in the upper cover22for sterilization before and after the experiment, and the lighting tube is installed to simulate the effects of a different light on the organism when being in the dark.

Specifically, one end of the air pipe14is provided with a pipe filter device8. The pipe filter device8includes a connection pipe81threaded with the air pipe14.
