[0023] The utility model is a one-to-two constant temperature test device, comprising a main test box 1, and also comprising a first small test box 2 and a second small test box 3, wherein the first small test box 2 is provided with a first test chamber 21, and the second small test box 3 is provided with a second test chamber 31; a main test chamber 11 is provided inside the main test box 1, and a temperature control mechanism 12 for providing high-temperature or low-temperature airflow to the main test chamber 11 is also provided inside the main test box 1; the main test chamber 11 is connected to the first test chamber 21 through a first air inlet duct 13 and a first air return duct 14, and the main test chamber 11 is connected to the second test chamber 31 through a second air inlet duct 15 and a second air return duct 16.

[0024] The utility model connects the small test boxes with the air inlet duct and the air return duct on both sides of the main test box 1 respectively, and the three test boxes can realize a variety of independent test schemes. For example, the air inlet duct and the air return duct are blocked, and the main test box 1 is opened alone to form a traditional constant temperature test box, which is suitable for independent testing of a single test product; the three test boxes can also be enabled at the same time. At this time, different parts are placed in the three test boxes at the same time and the test is started together, which has the highest test efficiency; the main test box 1 can also be opened, and product testing is only carried out in the two small test boxes. This solution is suitable for independent testing of different parts in the same environment and at the same time, and the detection accuracy is relatively high; in general, the utility model has more diversified functions and higher test efficiency, and can also meet the existing production needs of multiple spare parts that need to be independently tested at the same time.

[0025] Preferably, the first air inlet duct 13 and the second air inlet duct 15 are provided with a first fan 17 at one end close to the main test chamber 11; the first return air duct 14 and the second return air duct 16 are provided with a second fan 18 at one end close to the main test chamber 11; the first fan 17 and the second fan 18 are arranged in opposite directions to each other. The first fan 17 guides the airflow to be transmitted to the first small test box 2 and the second small test box 3, and the second fan 18 guides the airflow from the first small test box 2 and the second small test box 3 back to the main test chamber 11. The first fan 17 and the second fan 18 play a guiding role to accelerate the transmission of the airflow.

[0026] Preferably, the first air inlet duct 13, the second air inlet duct 15, the first air return duct 14 and the second air return duct 16 are all provided with a polyurethane insulation layer to prevent the extreme temperature of the high-temperature airflow or the low-temperature airflow from being directly transferred to the outer wall of the duct to threaten the personal safety of the staff.

[0027] Preferably, the front end of the first small test box 2 is detachably connected with a first inclined door panel 22. The first inclined door panel 22 is located at the top of the small test box, which is convenient for opening the small test box to place or take out the test sample.

[0028] As another embodiment, the rear end of the first small test box 2 is detachably connected with a second door panel 23. The second door panel 23 is located on the side of the small test box, and the second door panel 23 facilitates the staff to take out samples at specific locations in time.

[0029] As another embodiment, the second door panel 23 is provided with a plurality of observation windows 24 , through which the staff can observe and record the entire test process in real time.

[0030] Preferably, the first small test box 2 and the second small test box 3 are both provided with a plurality of rubber sleeves 4 on the outside. If the product tested in the small test box needs to use external transmission shafts and other parts to complete the test process, the transmission shaft can be introduced into the test chamber through the rubber sleeve 4. The rubber sleeve 4 is a flexible component, which makes the assembly process more convenient and can ensure the sealing of the test process.

[0031] As an embodiment, the main test box 1 is provided with a control panel 19 to control the entire test device.

[0032] In the technical solution, the temperature control mechanism 12 includes an air duct 121 and a third fan 122, a heater 123 and an evaporator 124 sequentially arranged inside the air duct 121; an air inlet 125 is arranged above the air duct 121 and an air return port 126 is arranged below the air duct 121 and the main test chamber 11, the third fan 122 is arranged at the air inlet 125, and the heater 123 and the evaporator 124 are arranged between the air inlet 125 and the air return port 126. The third fan 122 guides the air flow to enter the main test chamber 11 from the air inlet 125, and the air flow then flows back to the air duct 121 from the air return port 126 and passes through the evaporator 124 and the heater 123 in sequence, and the evaporator 124 or the heater 123 is turned on as needed, thereby forming a low-temperature or high-temperature air flow.

[0033] To further improve the technical solution, a humidifying boiler 127 is further provided between the heater 123 and the evaporator 124. The humidifying boiler 127 can add a humidity test on the basis of high and low temperature tests, further expanding the application scope of the entire test device.

[0034] The operating principle of the utility model is as follows: the temperature control mechanism 12 inside the main test box 1 is turned on, and the temperature control mechanism 12 generates high and low temperature airflows to supply the main test chamber 11, and then the high temperature airflow is transmitted to the first small test box 2 and the second small test box 3 under the action of the first fan 17, and after the airflow blows through the tested product, it flows back to the main test box 1 under the guidance of the second fan 18.

[0035] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
