Description

Technical Field

[0001] This utility model relates to the field of hot air blower technology, specifically a graphene-heated hot air blower. Background Technology

[0002] A hot air blower is a piece of equipment used in industrial production, mainly composed of three parts: a blower, a heater, and a control circuit. Its working principle is to convert electrical energy into heat energy through heating an electric heating wire, thereby generating hot air. Hot air blowers have wide applications in industry, commonly used in drying, baking, and welding processes. They are the optimal hot air source configuration for automated facilities such as precision hot air conveying furnaces, drying ovens, and baking ovens. With the advancement of technology, graphene is now often used as a heating element.

[0003] A search revealed a graphene-based hot air blower disclosed in patent application CN201920447583.0. The hot air blower includes a housing with an internal chamber. The inner wall of the chamber is provided with a sealed insulation layer. The housing has a lower cold air inlet and an upper hot air outlet. The lower cold air inlet is equipped with an automatically adjusting hood, and the upper hot air outlet is equipped with a temperature-controlled fan and a damper. The chamber includes at least one heat-collecting cavity. The lower part of the heat-collecting cavity has a cold air inlet channel communicating with the lower cold air inlet, and the upper part has a hot air outlet channel communicating with the upper hot air outlet. The outer side of the heat-collecting cavity is sequentially provided with a finned heat dissipation layer, a heat storage layer, a heating layer, and a reflective film. The heating layer is made of graphene heating material. This graphene-based hot air blower has the advantages of low energy consumption, fast heating speed, and good heating effect.

[0004] However, this patent has its shortcomings. The air passage in this graphene-heated hot air blower is relatively short, which can easily lead to uneven heating of the incoming air during actual use, affecting the heating effect. In addition, the air inlet of the device lacks a filter component, so when the device is working, dust in the outside air can easily enter the device and adhere to the heat dissipation layer of the fins, affecting the heat exchange efficiency of the device.

[0005] To address this, we propose a graphene-based heating hot air blower. Utility Model Content

[0010] Optionally, multiple mounting bases are arranged alternately in the upper and lower parts of the hot air blower housing. This design increases the air travel distance and improves the heating effect.

[0011] Optionally, a plurality of cleaning needles are fixedly installed at the bottom of the pressure plate. By inserting the plurality of cleaning needles into the mesh of the dust filter, the dust adhering to the bottom of the dust filter can be pushed out.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3This utility model provides a graphene-heated hot air blower, including a hot air blower housing 1. Multiple mounting seats 14 are fixedly installed inside the hot air blower housing 1. Graphene heating plates 13 are fixedly installed in each of the mounting seats 14. Multiple heat-conducting plates 15 are fixedly installed on one side of each graphene heating plate 13. The sides of the multiple heat-conducting plates 15 away from the graphene heating plate 13 extend out of the mounting seat 14. An air inlet seat 2 is fixedly installed on the left side of the hot air blower housing 1. A dust filter 7 is fixedly installed at the bottom of the air inlet seat 2, and a [missing information - likely a device or component] is fixedly installed at the top of the air inlet seat 2. Two uprights 21 are connected to a geared disc 10 on the left side of the hot air blower housing 1, which is rotatably connected between the two uprights 21. A slide rod 18 is fixedly installed on the left side of the geared disc 10. A lifting frame 19 is slidably sleeved on the outside of the slide rod 18. A push rod 17 is fixedly installed at the bottom of the lifting frame 19. A pressure plate 9 is set at the top of the air inlet seat 2. Multiple cleaning needles 8 are fixedly installed at the bottom of the pressure plate 9. The bottom of the push rod 17 extends into the air inlet seat 2 and is fixedly installed on the pressure plate 9. An air outlet pipe 4 is fixedly installed on the right side of the hot air blower housing 1. A blower 16 is fixedly installed inside the air outlet pipe 4.

[0022] Rain shelters 3 are fixedly installed on the top of the two uprights 21. These shelters protect the gear disc 10 and lifting frame 19 from rain. A motor 12 is fixedly installed inside the rain shelter 3, and a gear 11 is fixedly installed on the output end of the motor 12. The gear 11 meshes with the gear disc 10, and the motor 12 drives the gear 11 to rotate, facilitating the use of this equipment. Multiple mounting seats 14 are staggered vertically within the hot air blower housing 1. This design increases the air travel distance and improves the heating effect. The pressure plate 9 has a bottom... Multiple cleaning needles 8 are fixedly installed at the end. By inserting the cleaning needles 8 into the mesh of the dust filter 7, the dust adhering to the bottom of the dust filter 7 can be pushed out. Slider 20 is fixedly installed at both the front and rear ends of the lifting frame 19. The two sliders 20 are slidably connected to the two uprights 21 respectively. The sliders 20 can limit the lifting frame 19. A control box 5 is fixedly installed at the front end of the hot air blower housing 1. A PLC controller 6 is fixedly installed in the control box 5. The PLC controller 6 facilitates the control of this equipment.

[0023] Working Principle: During use, the air outlet duct 4 is connected to the indoor air supply duct. When the indoor temperature is low, turning on the hot air switch activates multiple graphene heating plates 13, which then transfer heat to multiple heat-conducting plates 15. The blower 16 operates, drawing in outside air through the air inlet 2. The air then passes between the graphene heating plates 13, forming hot air, which then flows through the air outlet duct 4 into the indoor air supply duct for heating. As the air passes through the air inlet 2, dust is filtered by the dust filter 7. When the equipment stops working, the PLC controller 6 starts the motor 12. The motor 12 drives the gear 11 and gear disc 10 to rotate. The gear disc 10 drives the slide rod 18 to rotate in a circular direction. The slide rod 18 slides within the lifting frame 19, causing the lifting frame 19 to move up and down reciprocally. When the lifting frame 19 pushes down the push rod 17, the pressure plate 9, and multiple cleaning needles 8, it can push out the dust in the mesh of the dust filter 7. At the same time, when the pressure plate 9 hits the dust filter 7, it will cause the dust filter 7 to vibrate, causing the dust to fall off and preventing dust from adhering to the dust filter 7 and affecting the next use. This type of graphene heating hot air blower is easy to use. The above components can increase the travel of air through the hot air blower housing 1, ensuring that the air is heated evenly, thereby further improving the heating effect of this type of hot air blower. At the same time, the dust filter 7 can filter dust during use, preventing dust from entering and affecting the heat exchange effect of the equipment. And it can automatically clean the dust on the dust filter 7 after each use, preventing dust from clogging the mesh of the dust filter 7 and affecting the next use.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
