DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1 See also Figure 1-7 The present invention provides the following technical solutions: an automatic adjustment device for environmental conditions in a constant temperature and humidity laboratory, comprising a constant temperature and humidity machine body 1, an exhaust duct 7 and a return air duct 8 are installed at one end of the constant temperature and humidity machine body 1, a side panel 2 is installed on the side wall of the constant temperature and humidity machine body 1, a water injection pipe 15 and a drainage pipe 14 are connected to the same end of the constant temperature and humidity machine body 1 as the exhaust duct 7 and the return air duct 8, a baffle 9 is provided at the front end of the exhaust duct 7 and the return air duct 8, a connecting block 10 is installed on the surface of the exhaust duct 7 and the return air duct 8, and an electric rod 11 is installed at one end of the connecting block 10.

[0023] In the preferred embodiment: the telescopic end of the electric rod 11 is connected to the back end of the baffle 9 , and the baffle 9 is telescopically connected to the ends of the exhaust duct 7 and the return duct 8 through the electric rod 11 .

[0024] In the embodiment, firstly, the automatic adjustment device for the environmental conditions of the constant temperature and humidity laboratory is usually called a constant temperature and humidity machine; the constant temperature and humidity machine realizes the precise adjustment of the laboratory environmental conditions by integrating advanced sensors, controllers and actuators. Its working principle is mainly based on the following key components: Sensors: used to monitor temperature and humidity in the laboratory in real time. These sensors are usually highly sensitive and accurate, and can quickly sense small changes in environmental conditions; Controller: Receives data from sensors and analyzes and judges based on the preset temperature and humidity range. When environmental conditions deviate from the set values, the controller will issue instructions to activate the corresponding actuators for adjustment. Actuators: These include heaters, coolers, humidifiers, dehumidifiers, etc. These devices precisely regulate the temperature and humidity in the laboratory according to the instructions of the controller.

[0025] In addition, the movement of the baffle 9 can be precisely controlled by the telescopic function of the electric rod 11. When the constant temperature and humidity machine body 1 needs to be activated, the telescopic end of the electric rod 11 pushes the baffle 9 to move, thereby exposing the outlets of the exhaust duct 7 and the return duct 8 to ensure the normal ventilation and operation of the equipment. When the equipment is not in use, the electric rod 11 drives the telescopic end to retract, so that the baffle 9 covers the outlets of the exhaust duct 7 and the return duct 8 again.

[0026] This design not only realizes the automatic control of the baffle 9 and improves the convenience of operation, but more importantly, it effectively prevents animals from entering the equipment through the exhaust duct 7 and the return air duct 8, avoids the risk of equipment short circuit caused by animals gnawing on the circuits, and significantly enhances the safety of the equipment.

[0027] Embodiment 2 See also Figure 1-7 The exhaust duct 7 is equipped with a diverter plate 19 inside, the outer wall of the diverter plate 19 is installed with a first slider 21, the inner wall of the cavity of the exhaust duct 7 is provided with a first slide groove 20, and the outer wall of the exhaust duct 7 is threadedly connected with a first bolt 22.

[0028] In the preferred embodiment: the diverter plate 19 is slidably connected to the exhaust pipe 7 via the first slider 21 and the first slide groove 20 , and the first bolt 22 passes through the outer wall of the exhaust pipe 7 and is threadedly connected to the first slider 21 .

[0029] In the embodiment, according to the description of the first embodiment, when the thermostatic and hygrostatic machine body 1 is working, the baffle 9 is in an open state, and then the air enters from the return air duct 8, and then passes through the thermostatic and hygrostatic machine body 1 and is discharged from the exhaust duct 7, and a splitter 19 is cleverly designed inside the exhaust duct 7. This design effectively disperses the airflow discharged from the thermostatic and hygrostatic machine body 1, and avoids the airflow being too strong and blowing the objects or papers in the laboratory, thereby reducing interference during the experiment. At the same time, the evenly distributed airflow also reduces the adverse effects of overly dry or humid air on the respiratory system and skin of personnel, and improves the working environment and comfort of personnel in the laboratory.

[0030] In addition, when the diverter plate 19 needs to be taken out and replaced, it can be easily disassembled and assembled by the first bolt 22 , which passes through the outer wall of the exhaust pipe 7 and is threadedly connected with the first slider 21 .

[0031] Embodiment 3 See also Figure 1-7 The return air duct 8 is internally equipped with an annular block 16 , a filter screen 17 is disposed at the front end of the annular block 16 , and a screw 18 is connected to the surface of the metal frame outside the filter screen 17 .

[0032] In the preferred embodiment, the filter screen 17 is made of metal, and the filter screen 17 is threadedly connected to the annular block 16 via screws 18 .

[0033] In the embodiments, as described in Embodiment 1, when the constant temperature and humidity machine body 1 is working, the baffle 9 is in an open state, and then air enters from the return air duct 8. A filter screen 17 is installed inside the return air duct 8. This measure effectively blocks dust and impurities in the laboratory from entering the interior of the constant temperature and humidity machine body 1, ensuring the normal operation of the equipment and extending its service life. Through the filtering effect of the filter screen 17, the dust accumulation and pollution inside the equipment are reduced, and the stability and reliability of the equipment are improved.

[0034] In addition, in order to clean or replace the filter screen 17, only need to remove the screw 18, and the connection between the filter screen 17 and the annular block 16 can be released, realizing convenient disassembly and assembly operations.

[0035] It should be noted that in the above-mentioned Embodiment 2 and Embodiment 3, in order to replace the filter screen 17 and the flow dividing plate 19, first, the baffle 9 needs to be disassembled and assembled from the telescopic end of the electric rod 11. The electric rod 11 and the baffle 9 are firmly connected through a connecting piece. Once the baffle 9 is removed, the filter screen 17 and the flow dividing plate 19 can be accessed without obstruction, so that their replacement operations can be carried out smoothly.

[0036] Embodiment 4 Please refer to Figure 1-7 , the same end of the constant temperature and humidity machine body 1 as the exhaust air duct 7 and the return air duct 8 is also connected with a touch panel 12. A protective plate 13 is provided at the front end of the touch panel 12. The protective plate 13 is in a U shape and its end is connected with a second slider 25. A limiting groove 26 is connected to the outer side wall of the second slider 25.

[0037] Preferably in the embodiment: Fixed blocks 23 are connected to both sides of the touch panel 12. A second sliding groove 24 is opened at the front end of the fixed block 23. The second slider 25 is adapted to the second sliding groove 24 and is in a T shape. The second slider 25 is assembled in the second sliding groove 24 and the protective plate 13 is slidably connected to the front end of the fixed block 23 through the second slider 25.

[0038] Preferably in the embodiment: A convex block 27 is connected to the outer side wall of the fixed block 23. A pull rod 28 is installed inside the convex block 27. A limiting plate 30 is connected to the surface of the pull rod 28. A spring 29 is sleeved on the surface of the pull rod 28. The pull rod 28 is elastically movably connected to the inside of the convex block 27 through the spring 29, and the end of the pull rod 28 passes through the convex block 27 and the fixed block 23 and is inserted into the limiting groove 26.

[0039] In the embodiment, according to the description of the first embodiment, when the constant temperature and humidity machine body 1 is working, the touch panel 12 can observe the environmental conditions of the laboratory and control the operation of the constant temperature and humidity machine body 1. Subsequently, a protective plate 13 is designed at the front end of the touch panel 12. This design effectively protects the touch panel 12 from collision damage and ensures the normal operation of the device. The presence of the protective plate 13 reduces the damage to the touch panel 12 caused by accidental collisions, improves the durability of the device and the user experience.

[0040] In addition, the protective plate 13 is made of transparent plastic material. To open the protective plate 13, first place your palm against the front end of the protective plate 13, and then use your other hand to operate the pull rod 28 to make it work. During the movement, the pull rod 28 will drive the limit plate 30 to compress the spring 29, causing a contraction deformation, and then the pull rod 28 can be smoothly moved out of the limit groove 26. Next, slide the protective plate 13 downward, and this action will drive the second slider 25 to slide smoothly along the second slide groove 24. As the protective plate 13 moves, the touch panel 12 is exposed, and the user can use the touch panel 12 to start or adjust the working data of the constant temperature and humidity machine body 1.

[0042] In the embodiment, the application of the second bolt 4 enables the side panel 2 to be easily disassembled and assembled, greatly facilitating the maintenance work of maintenance personnel. When the second bolt 4 is rotated to a specific position, the connection with the side panel 2 can be released, while it is still connected to the support frame 3, avoiding the inconvenience of finding after complete disassembly. On the other hand, the third bolt 6 ensures the convenient installation and use of the constant temperature and humidity machine body 1 through the mounting frame 5, further improving the convenience of installation.
