Description

Technical Field

[0001] The utility model relates to the technical field of mosquito-repellent incense drying experimental equipment, in particular to an electric heating constant temperature drying box for mosquito-repellent incense drying test. Background Art

[0002] At present, electric constant temperature drying oven is suitable for industrial and mining enterprises, laboratories, scientific research units and other departments for drying, melting wax, sterilization, etc. Electric constant temperature drying oven is often called constant temperature drying oven or drying oven.

[0003] When conducting a drying experiment on wet mosquito coils, a constant temperature drying oven is used for drying and data is recorded. An existing hot air box outlet inside a drying oven discharges hot air through a row of round holes to conduct a drying experiment on mosquito coils. In the experimental test, the data obtained when hot air is blown to the mosquito coils at different angles is different. However, the data obtained from the mosquito coil drying experiment using an outlet at a fixed angle is relatively single, which reduces the accuracy of the experimental data. Utility Model Content

[0004] The utility model aims to provide an electric constant temperature drying box for mosquito coil drying test to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric constant temperature drying oven for mosquito coil drying test, comprising a drying oven main body, a hot air box fixedly installed inside the drying oven main body, an air outlet of the hot air box rotatably connected to a rotating rod, an outer wall of the rotating rod fixedly connected to an air induced blade, one side of the hot air box is fixedly connected to a slide groove, an inner wall of the slide groove is clamped with a rack, one end of the rotating rod is fixedly connected to a gear, the gear and the rack are meshingly connected, a stepper motor is fixedly installed on the inner wall of the drying oven main body, the rotating shaft of the stepper motor is fixedly connected to one end of the rotating rod, and a controller is fixedly installed on the inner wall of the drying oven main body.

[0006] By adopting the above technical solution, the shape, speed and direction of the stepper motor are controlled by the controller, so that the stepper motor drives the rotating rod and the air induced blades to rotate, and the gear on the top rotating rod causes the meshing rack to move vertically. The vertical movement causes the meshing gear and the rotating rod below to rotate together, so that all the air induced blades can rotate synchronously to the specified angle.

[0007] Preferably, an air blowing device is fixedly installed inside the drying box body, a display screen is fixedly installed on the outer wall of the drying box body, and a control switch is fixedly installed on the outer wall of the drying box body.

[0008] By adopting the above technical solution, the temperature of the drying box body and the wind speed of the blowing device can be controlled by controlling the switch and the display screen, and mosquito coils can be tested under different drying conditions to improve the diversity of experimental detection data.

[0009] Preferably, a universal micro-wind speed probe is fixedly installed on the inner top of the drying box body, a universal micro-wind speed meter is fixedly installed on the inner wall of the drying box body, and a temperature and humidity detector is fixedly installed on the inner top of the drying box body.

[0010] By adopting the above technical solution, by installing the universal micro-wind speed probe inside the drying box body, the internal wind speed can be monitored in real time. The data is obtained by the universal micro-wind speed meter, which replaces the problem of inaccurate breeze data caused by opening the box door for testing in the existing technology, thereby improving the accuracy of the experimental data. At the same time, the installation of a temperature and humidity detector can monitor the internal temperature and humidity in real time.

[0011] Preferably, the stepper motor is a small motor with a diameter of thirty centimeters, and the stepper motor, the controller and the control switch are electrically connected.

[0012] By adopting the above technical solution, by installing a 30-centimeter small stepper motor, it is possible to ensure that the rotating rod can be driven to rotate while reducing the size of the motor so that there is enough space inside to install other structures. At the same time, the speed and direction of the stepper motor can be controlled by controlling the switch and controller, so that the air outlet angle can be adjusted as required.

[0013] Preferably, the air outlet of the hot air box is rotatably connected to a row of rotating rods and air-inducing blades, and one end of each rotating rod is fixedly mounted with a gear that meshes with a rack.

[0014] By adopting the above technical solution, the meshing rack can be moved up and down by rotating the top rotating rod and the gear. When moving, the meshing gears connected below the rack will drive their respective rotating rods to rotate, so that when the top air induced blades rotate, all the air induced blades rotate at the same angle together, ensuring that the mosquito coils are dried at different angles, thereby improving the accuracy of the experimental data.

[0015] Preferably, the universal micro-wind speed probe is electrically connected to the universal micro-wind speed meter, and the universal micro-wind speed meter and the temperature and humidity detector are electrically connected to the display screen.

[0016] By adopting the above technical solution, the universal micro-wind speed probe will transmit the detection signal to the universal micro-wind speed meter to obtain data, and the temperature and humidity detector will detect the temperature and humidity data. At the same time, the two sets of data will be transmitted to the display screen for the convenience of experimenters to record.

[0017] Preferably, the outer wall of the rack fits with the inner wall of the slide groove, and the upper and lower ends of the rack are aligned with the upper and lower ends of the hot air box.

[0018] By adopting the above technical solution, the rack and the slide groove are closely connected to each other, so that the gears of the structural instrument are compactly connected, and the problem of different adjustment angles caused by loose connection can be avoided during operation adjustment. At the same time, a sufficiently long rack can meet the length of the gear rotation, ensuring that any angle can be adjusted for experimental testing.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] (1) The controller controls the shape, speed and direction of the stepper motor, so that the stepper motor drives the rotating rod and the air duct blades to rotate. The gear on the top rotating rod causes the meshing rack to move vertically. The vertical movement causes the meshing gear and the rotating rod below to rotate together, so that all the air duct blades rotate synchronously to the specified angle, so that the experiment can dry mosquito coils at different exhaust angles to obtain data, thereby improving the accuracy of the mosquito coil experimental test data.

[0021] (2) By installing a universal micro-wind speed probe inside the drying box body, the internal wind speed can be monitored in real time. The universal micro-wind speed meter can obtain data, and the temperature and humidity detector can monitor the internal temperature and humidity in real time. The two sets of data are displayed on the display screen to facilitate the experimenter to record. It is used to replace the existing technology that requires opening the box door to test the wind speed and temperature and humidity, reducing the problem of inaccurate data caused by opening the box door for testing, thereby improving the accuracy of the experimental data.
