Air fryer purification device Technical Field

[0001] This utility model relates to the field of purification technology, specifically a purification device for air fryers. Background Technology

[0002] An air fryer is a modern kitchen appliance widely popular for its healthy and convenient cooking methods. It utilizes high-speed air circulation technology, replacing the large amounts of cooking oil required for traditional frying with hot air convection, thus significantly reducing oil usage and better aligning with modern lifestyles that prioritize healthy eating. Air fryers are easy to operate; users simply place the food in the basket, set the time and temperature, and cooking begins. It heats food quickly and evenly, preserving its original texture and nutrients while achieving a crispy finish similar to deep-frying.

[0003] During cooking in an air fryer, the high temperatures cause a series of chemical reactions between oils and food, which may produce gases harmful to the human body. These harmful gases are generally released directly into the air, posing a potential health risk. Therefore, a purification device for air fryers is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a purification device for air fryers to solve the problem that harmful gases are generally directly emitted into the air in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a purification device for an air fryer, comprising an air fryer shell, an air fryer body inside the air fryer shell, a metal shell fixedly installed inside the air fryer shell, a motor fixedly installed inside the metal shell, a drive shaft fixedly installed at the output end of the motor, a first fan blade fixedly installed at the end of the drive shaft, a heating element fixedly installed below the first fan blade, a purification mechanism installed on the metal shell, and an oil fume treatment mechanism connected to the purification mechanism.

[0006] Preferably, the purification mechanism includes a gas pipe fixedly installed on a metal casing, a fan connected to the gas pipe and then to the purifier, a transmission shaft between the drive shaft and the fan, a clutch on both the transmission shaft and the drive shaft, and helical gears on both the transmission shaft and the drive shaft, with the two sets of helical gears meshing together.

[0007] Preferably, the fryer shell is provided with a retainer, the drive shaft is rotatably mounted between the drive shaft and the fan through the retainer, and one end of the drive shaft passes through a gas pipe.

[0008] Preferably, the first fan blade is rotatably mounted above the heating element via a drive shaft, and through holes are provided at both sides of the metal housing, with the two ends of the gas pipe connected to the metal housing through the through holes.

[0009] Preferably, the fume treatment mechanism includes a housing connected to one end of the gas duct and a second fan blade fixedly installed at the end of the drive shaft. An oil cup is connected to the bottom of the housing, and an air inlet is provided on the side wall of the oil cup. A heat dissipation coil is fixedly installed in front of the second fan blade. A heat exchange coil is fixedly installed inside the housing. A circulation pipe is provided between the heat dissipation coil and the heat exchange coil, and a circulation pump is installed on the circulation pipe.

[0010] Preferably, the bottom of the mechanism housing is provided with threads, and the oil cup is threadedly connected to the bottom of the mechanism housing.

[0011] Preferably, the second fan blade is rotatably mounted on one side of the heat dissipation coil via a drive shaft, heat dissipation holes are provided on the side wall of the fryer shell and are aligned with the heat dissipation coil, and a through hole is provided on the mechanism housing, through which the circulation pipe extends into the mechanism housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, the motor can be started after the clutch on the drive shaft is engaged. After the motor starts, the drive shaft will drive the drive shaft to rotate. The rotation of the drive shaft will then drive the fan and the second fan blades. The operation of the fan will cause the gas inside the fryer to circulate in the gas pipe. During the gas circulation process, the purifier will purify the gas to effectively purify the harmful gases generated during the heating process.

[0014] 2. In this application, during the purification process, oil fumes enter the housing of the mechanism through the air inlet. Subsequently, a circulation pump can be activated, causing the coolant to circulate between the radiator coil and the heat exchange coil. Inside the heat exchange coil, the coolant exchanges heat with the high-temperature oil fumes, and under the action of the second fan blade, the coolant is cooled, causing the oil fumes to liquefy and drip into the oil cup. Furthermore, the user can rotate the oil cup to remove it for easy cleaning of the oil stains. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] As shown in Figures 1, 2, and 3, this utility model provides a technical solution for a purification device for an air fryer, including an air fryer shell 1, an air fryer body 2 inside the air fryer shell 1, a metal shell 3 fixedly installed inside the air fryer shell 1, a motor 4 fixedly installed inside the metal shell 3, a drive shaft 5 fixedly installed at the output end of the motor 4, a first fan blade 6 fixedly installed at the end of the drive shaft 5, a heating element 7 fixedly installed below the first fan blade 6, a purification mechanism 8 installed on the metal shell 3, and an oil fume treatment mechanism 9 connected to the purification mechanism 8. Through the combined use of the purification mechanism 8 and the oil fume treatment mechanism 9, the oil fumes and harmful gases generated by the air fryer can be purified.

[0023] As shown in Figures 3 and 4, the purification mechanism 8 includes a gas pipe 801 fixedly installed on the metal housing 3. A fan 805 and a purifier 802 are connected to the gas pipe 801. A transmission shaft 803 is provided between the drive shaft 5 and the fan 805. Both the transmission shaft 803 and the drive shaft 5 are equipped with clutches 804. Both the transmission shaft 803 and the drive shaft 5 are equipped with helical gears 806, and the two sets of helical gears 806 mesh together. A retainer is provided inside the fryer housing 1. The transmission shaft 803 is rotatably installed between the drive shaft 5 and the fan 805 through the retainer, and one end of the transmission shaft 803 passes through the gas pipe 801.

[0024] Specifically, after the clutch 804 on the drive shaft 803 is successfully engaged, the motor 4 can be started. Once the motor 4 is started, it will drive the drive shaft 803 to rotate. The rotation of the drive shaft 803 will be transmitted to the fan 805 and the second fan blade 903, causing them to start operating as well. As the fan 805 operates, it promotes the circulation of gas inside the fryer body 2 within the gas pipe 801. When the gas inside the fryer body 2 circulates within the gas pipe 801, the purifier 802 will purify the gas, effectively removing harmful gases generated during the heating process, ensuring a clean and safe environment.

[0025] As shown in Figures 3 and 5, the fume treatment mechanism 9 includes a housing 901 connected to one end of the gas duct 801 and a second fan blade 903 fixedly installed at the end of the drive shaft 803. An oil cup 907 is connected to the bottom of the housing 901. An air inlet 908 is provided on the side wall of the oil cup 907. A heat dissipation coil 904 is fixedly installed in front of the second fan blade 903. A heat exchange coil 906 is fixedly installed inside the housing 901. A circulation pipe 902 is provided between the heat dissipation coil 904 and the heat exchange coil 906. A circulation pump 905 is installed on the circulation pipe 902. The bottom of the housing 901 is threaded. The oil cup 907 is threadedly connected to the bottom of the housing 901.

[0026] Specifically, during the purification process, the oil fumes first enter the housing 901 through the air inlet 908. At this stage, the circulation pump 905 can be activated. Once the circulation pump 905 is activated, the coolant begins to circulate between the radiating coil 904 and the heat exchange coil 906. When the coolant flows to the heat exchange coil 906, it exchanges heat with the high-temperature oil fumes, thereby reducing the temperature of the oil fumes. Simultaneously, the coolant also flows through the radiating coil 904, where it is further cooled by the action of the second fan blade 903. In this way, the oil fumes are effectively liquefied and drip into the oil cup 907. For easy cleaning, the oil cup 907 is threaded onto the housing 901, allowing the user to easily rotate and remove it to clean the oil residue, maintaining the cleanliness and efficient operation of the equipment.

[0027] Working principle: After cooking is completed, the clutch 804 on the drive shaft 803 can be engaged. After the clutch 804 on the drive shaft 803 is engaged, the motor 4 can be started. After the motor 4 is started, the drive shaft 5 will drive the drive shaft 803 to rotate. After the drive shaft 803 rotates, it will drive the fan 805 and the second fan blade 903 to operate. After the fan 805 operates, it will drive the gas in the fryer body 2 to circulate in the gas pipe 801. When the gas in the fryer body 2 circulates in the gas pipe 801, it will be purified by the purifier 802, thereby purifying the harmful gases generated by heating. During the purification process, the oil fumes enter the housing 901 of the mechanism through the air inlet 908. At this time, the circulation pump 905 can be started. After the circulation pump 905 is started, the coolant will circulate between the heat dissipation coil 904 and the heat exchange coil 906. The coolant flowing into the heat exchange coil 906 will exchange heat with the high-temperature oil fumes, while the coolant flowing into the heat dissipation coil 904 will be cooled down by the action of the second fan blade 903, thereby liquefying the oil fumes and dripping them into the oil cup 907. The user can rotate the oil cup 907 to remove it for easy cleaning of the oil stains in the oil cup 907.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
