[0024] The present invention will be described in further detail below with reference to the accompanying drawings.

[0025] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0026] Example 1:

[0027] See also Figures 1-6The figure shows a new type of high-efficiency electric hot air furnace, including the equipment body 1. The electric hot air furnace equipment body 1 adopts the 5LD12KW TA model. Its working principle is to use carbon fiber heating tubes as the heat source, and then use a fan to send a large amount of heat to the remote end. There are nine heating tubes, which are evenly distributed along the air outlet. This machine adopts an automatic temperature control device. When the greenhouse temperature drops to the set temperature, the hot air furnace automatically starts. When the temperature in the greenhouse reaches the required temperature, the hot air furnace automatically stops working. The equipment body 1 should be installed by dedicated personnel and hung at one end of the greenhouse, 1.8 meters above the ground, with the air outlet blowing toward the other end of the greenhouse. If multiple machines are installed in a greenhouse, the air outlet direction should be unified, which can enhance the air convection in the greenhouse and make the temperature in the greenhouse uniform. An air inlet 2 is installed on one side of the equipment body 1, and an air outlet 3 is installed on the side of the equipment body 1 away from the air inlet 2. The air outlet 3 has an extended design. A fan 26 is installed inside the air inlet 2. The fan flow rate is 3500 cubic meters / square. The surface of the fan 26 blades is coated with heavy-duty anti-corrosion nano-composite ceramic material, which can effectively reduce Dust adhesion, a baffle 4 is provided on the air inlet tube 2, and a protective cover 5 is fixedly connected to the outside of the baffle 4, and the protective cover 5 is fixedly connected to the air inlet tube 2, and also includes: a filter plate 20 installed on one side of the fan 26, the filter plate 20 is made of stainless steel metal filter material, this material has uniform pores, good air permeability and high mechanical strength, and can effectively filter impurities in the air, a cleaning component 6 is installed on one side of the filter plate 20, and the cleaning component 6 is used to clean the filter plate 20; and an anti-blocking component 7 installed on the cleaning component 6, the anti-blocking component 7 is used to prevent the filter plate 20 from being blocked.

[0028] Furthermore, the cleaning component 6 includes a sliding rod 9 symmetrically mounted on the baffle 4. The surface of the sliding rod 9 is finely polished and plated with a wear-resistant chrome layer to reduce the friction of the push plate 11 during the sliding process. The end of the sliding rod 9 away from the baffle 4 is fixedly connected to a connecting plate 10. Both connecting plates 10 are fixedly connected to the inner wall of the air inlet tube 2 to facilitate improving the stability of the equipment.

[0029] Furthermore, an electric push rod 8 is installed on the outside of the baffle 4, and the output end of the electric push rod 8 is fixedly connected to a push plate 11, and the push plate 11 is slidably connected to the slide rod 9. A motor 12 is installed on the outside of the push plate 11, and the outside of the motor 12 is fixedly connected to a fixed block 13 through a coupling. A sensor 14 is installed on the top of the fixed block 13, and the sensor 14 is used to sense the positions of the cam 17 and the protrusion 21, so as to facilitate the adjustment of the position of the cleaning component 6.

[0030] Specifically: the outside of the fixed block 13 is symmetrically fixedly connected with a rotating rod 15, and a cleaning brush 16 is installed at the end away from each other of the two rotating rods 15. The bristles of the cleaning brush 16 are made of nylon, which has good flexibility and strong wear resistance. The outside of one of the rotating rods 15 is connected to a cam 17 through a rotating shaft, and a cleaning component 6 is also provided. The rotating rod 15 is driven to rotate by the motor 12, and then the cleaning brush 16 is driven to rotate, so that impurities on the surface of the filter plate 20 can be cleaned, thereby keeping the fan 26 blades clean and tidy, and thus keeping the electric hot air furnace running efficiently.

[0031] Example 2: This embodiment further explains Example 1. Figure 3-Figure 6 As shown, it is worth mentioning that the anti-blocking component 7 includes a filter frame 18 installed on the outside of the filter plate 20. The edge of the filter frame 18 of the anti-blocking component 7 is provided with a sealing strip. The sealing strip is made of high-temperature resistant and corrosion-resistant silicone rubber to ensure the sealing between the filter frame 18 and the air inlet tube 2, preventing unfiltered air from directly entering the equipment body 1. The inside of the filter frame 18 is symmetrically installed with a spring 19. The spring 19 is made of highly elastic stainless steel spring steel. During long-term compression and stretching, it can maintain stable elastic deformation ability to ensure the normal operation of the anti-blocking component 7. The spring 19 is fixedly connected to the filter plate 20. A protrusion 21 is fixedly installed on the outside of the filter plate 20. The surface of the protrusion 21 is anti-slip treated to increase the friction between the cam 17 and the cam 17 to ensure that the cam 17 can effectively hit the protrusion 21 during rotation, causing the filter plate 20 to vibrate. When the cam 17 rotates, it will hit the protrusion 21.

[0032] Specifically, the air inlet 2 is symmetrically provided with mounting holes 25, and the other mounting hole 25 is sealed by a sealing strip when not in use. The bottom of the two mounting holes 25 is provided with a mounting frame 22, and the mounting frame 22 is used to install the filter frame 18. The air inlet 2 is symmetrically provided with dust discharge holes 23, and the bottom of the two dust discharge holes 23 is provided with a collection box 24, which is used to collect the filtered impurities. The collection box 24 is made of transparent polycarbonate material, which is convenient for the staff to visually check the internal impurity collection situation and clean it in time. By providing a double-layer filter plate 20 and a filter frame 18, it can be realized. The filter plate 20 is now replaced without stopping the machine. The push plate 11 is pushed to move by the electric push rod 8, which in turn drives the motor 12 and the like to move to the appropriate position, so that the cam 17 hits the protrusion 21 while cleaning the filter plate 20, thereby causing the filter plate 20 to vibrate up and down, thereby preventing the filter plate 20 from being blocked, thereby facilitating the efficient operation of the electric hot air furnace. By cleaning the filter plate 20 in time and preventing it from being blocked, the fan blades of the fan 26 are kept clean and tidy, and the wear of the fan 26 caused by the entry of impurities is reduced, thereby extending the service life of the fan 26 and the entire electric hot air furnace, and reducing the replacement cost of the equipment.

[0033] The following are precautions for using a hot air furnace: A hot air furnace should be installed by a dedicated technician. The device (1) should be hung at one end of the greenhouse, 1.8 meters above the ground, with the air outlet directed toward the other end. If multiple devices are installed in a greenhouse, the air outlet direction should be uniform to enhance air convection and maintain a uniform temperature within the greenhouse. Once the device is installed, set the temperature according to the desired greenhouse temperature. For example, in a blueberry greenhouse, the optimal temperature at night is 11-13 degrees Celsius. We set the temperature to start at 11 degrees Celsius and stop at 13 degrees Celsius. After using the device (1) for about a week, disconnect the power supply, check all wiring points, tighten the screws to prevent loosening, and verify that the wiring is secure before continuing use. Every year before use, the equipment should be inspected in advance. If any component abnormality is encountered, it should be handled in time and used only when everything is normal. The power supply end of the hot air furnace must be equipped with a leakage protector. Each device must have a good grounding wire. It must be installed and debugged by a professional electrician. At the specified maximum output hot air temperature, the hot air temperature at the outlet should be no less than 80°C. The temperature sensor should be set 15m away from the hot air furnace outlet and have an over-temperature stop function.

[0034] In this solution, the principles are as follows:

[0035] First, when the new high-efficiency electric hot air furnace is started, the fan 26 starts to run, and the outside air is sucked into the device body 1 through the air inlet 2. In the process of air entering, it first passes through the filter plate 20, which intercepts dust, particles and other impurities in the air to ensure that the air entering the device body 1 is clean.

[0036] Next, when the filter plate 20 needs to be cleaned, the electric push rod 8 is activated, and its output end pushes the push plate 11 to slide along the slide rod 9, moving the motor 12, the fixed block 13 and other components to the appropriate position. At this time, the motor 12 is energized and drives the fixed block 13 to rotate through the coupling. The rotating rod 15 on the fixed block 13 rotates accordingly, and the cleaning brush 16 at one end of the rotating rod 15 also starts to rotate, cleaning impurities on the surface of the filter plate 20.

[0037] While cleaning brush 16 cleans filter plate 20, cam 17, connected to one of the rotating rods 15 via a rotating shaft, rotates continuously. When cam 17 reaches a specific position, it strikes a bump 21 on the outside of filter plate 20. Since filter plate 20 is mounted within filter frame 18 via springs 19, the impact causes filter plate 20 to vibrate up and down under the action of springs 19. This vibration loosens impurities stuck in the pores of filter plate 20, preventing clogging.

[0038] Finally, the impurities swept by the cleaning brush 16 and the impurities dropped due to the vibration of the filter plate 20 will fall into the collection box 24 below through the dust discharge hole 23 on the air inlet tube 2, thereby realizing the centralized collection of the impurities.

[0039] It should be noted that the electric push rod 8, motor 12, sensor 14 and fan 26 are all equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.

Furthermore, under the teachings of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
