Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-3 As shown, the utility model discloses an electric heater for precision ventilation, comprising:

[0026] The chassis is provided with a detachably connected air supply module, a heating module and a return air prevention module in sequence according to the direction of air flow. Specifically, the chassis includes a lower housing 11, a top cover 12, and a handle 13;

[0027] Air supply module, the air supply module comprises a first air duct 1, a fan 2 and a protective net 10, the fan 2 and the protective net 10 are installed on the first air duct 1;

[0028] A heating module, the heating module comprises a second air cylinder 3 and a heating tube 4, the heating tube 4 is installed on the second air cylinder 3, the shape of the heating tube 4 is not limited to a spiral shape, and any shape with high heating efficiency and high anti-corrosion ability can be used;

[0029] Anti-backflow module, used to control the opening and closing of the air outlet of the chassis;

[0030] When the air supply module is working, the external cold air is sent to the heating module for heating, and the heated hot air enters the livestock house through the anti-return air module.

[0031] The air supply module, the heating module and the anti-return air module are fastened by screws and other fasteners to achieve a detachable connection. Specifically, after the air supply module is fastened to the heating module, it is fastened to the anti-return air module, and then to the lower housing 11, the upper cover 12 is fastened to the lower housing 11, and the handle 13 is clamped on the lower housing.

[0032] Compared with the prior art, the present application has the following effects: first, the fan 2 of the air supply module works to send the external cold air into the heating module; then, the heating tube 4 starts to heat the external cold air, and the heated hot air enters the barn through the anti-return air module to heat the barn; finally, after the temperature in the barn reaches the set value, the fan 2 and the heating tube 4 stop working, and the anti-return air module closes the air outlet of the chassis, thereby preventing the external space from entering the barn. Therefore, the present application uses electricity instead of fuel oil, which saves costs, and has a large heating range, which is convenient for heating the entire barn. At the same time, the present application adopts a modular design, which is also convenient for repair and maintenance when the equipment fails.

[0033] Continuing with the above embodiment, more specifically, the anti-return air module includes a third air tube 8 and a louver blade 9, and the louver blade 9 is mounted on the third air tube 8. When in use, under the action of the fan 2, when hot air passes through the louver blade 9, the louver blade 9 will be pushed open, so that the hot air enters the livestock house; conversely, when the fan 2 stops working, the louver blade 9 will be reset under the action of gravity, thereby closing the air outlet of the chassis to prevent external air from entering the livestock house.

[0034] Following the above embodiment, more specifically, Figure 2 As shown, the first air duct 1, the second air duct 3 and the third air duct 8 are detachably connected to each other. The flanges of the first air duct 1, the second air duct 3 and the third air duct 8 are detachably connected by bolts, so that the modular design connection of the air supply module, the heating module and the anti-return air module is realized, which is convenient for repair and maintenance.

[0035] In accordance with the above embodiment, it is more preferred that a control module is further included, and the control module is electrically connected to the heating module and the air supply module respectively. In order to realize the automatic control of the device and solve the problems of excessive drying or insufficient drying when operated by personnel, the control module is automatically controlled, and the control module automatically controls the start and stop of the heating module and the air supply module according to preset parameters.

[0036] More specifically, the control module includes a control box body 6 and a main control board 7, and the main control board 7 is electrically connected to the fan 2 and the heating tube 4.

[0037] More specifically, the heating module further includes a temperature sensor 5 , and the temperature sensor 5 is electrically connected to the main control board 7 .

[0038] More specifically, it also includes an alarm light electrically connected to the main control board 7. When the fan 2 or the heating tube 4 fails, the temperature sensor 5 will send a signal to the main control board 7, and the main control board 7 will control the alarm light to automatically alarm.

[0039] The working process of the utility model is as follows:

[0040] The host computer sends a start command to the control module according to the temperature and humidity in the house. The main control board 7 of the control module receives the preset command to start the fan 2, and then starts a certain number of heating tubes 4 to start heating. The airflow blows open the louver blades 9 in the anti-return air module to send heat to the designated area. When the temperature and humidity in the house reach the set value, the host computer sends a stop command to the control module. After receiving the command, the main control board 7 stops the heating tube 4 from heating, and stops the fan 2 after a period of time, completing one operation. When the equipment fails, the internal temperature of the equipment will be abnormal after the fan 2 or the heating tube 4 fails. After the temperature sensor 5 uploads the equipment temperature, the program in the main control board 7 determines the abnormality, controls the alarm light to flash, and uploads the fault information to the host computer in the form of an alarm.

[0041] It can be seen that the present application can realize automatic control through the communication between the main control board 7 and the host computer, that is, the device automatically starts according to the command of the host computer, and the device automatically stops after reaching the set temperature.

[0042] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
