TECHNICAL FIELD

[0001] The utility model relates to a kind of air conditioning equipment and a kind of air heater, and more particularly to the technical field of air heater. BACKGROUND

[0002] Currently, in the related art, a part of users usually use air heater for heating, but the existing product is poor in user's heating experience due to the use of resistance heating mode, frequent on-off in the heating process. INVENTION CONTENTS

[0003] The utility model is aimed at at least solving one of the technical problems existing in the prior art or related art.

[0004] Therefore, the utility model provides a kind of air conditioning equipment according to the first aspect of the embodiment.

[0005] The utility model provides a kind of air heater according to the second aspect of the embodiment.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a kind of air conditioning equipment according to the first aspect of the embodiment, comprising: a shell cover; an electromagnetic heating device is arranged on the inner side of the shell cover; a wind deflector is arranged opposite to the electromagnetic heating device, and the electromagnetic heating device is used for heating the wind deflector; a fan wheel is arranged in the interior of the wind deflector, the fan wheel rotates, and air is discharged from the inner wall surface of the wind deflector, and the air is discharged outward from the front side of the shell cover after being guided by the wind deflector; wherein the wind deflector has an air inlet side and an air outlet side located on both sides of the axial direction, and the first caliber of the wind deflector on the air inlet side is smaller than the second caliber of the wind deflector on the air outlet side.

[0007] According to the air conditioning equipment provided by the utility model, it mainly comprises a shell cover and an electromagnetic heating device, a wind deflector and a fan wheel arranged in the shell cover. Specifically, the shell cover provides a solid protective housing for the air conditioning equipment, which not only protects the internal structure from damage, but also plays a role in heat insulation and insulation to ensure the safety of users during use. Specifically, the electromagnetic coil can be used as the electromagnetic heating device, and the material of the wind deflector is magnetic conductive material. By using the electromagnetic coil as the electromagnetic heating device, electromagnetic induction heating can be realized, which has the advantages of uniform heating and fast response, and is conducive to improving the heating efficiency and controlling the heating temperature. In addition, the wind deflector is made of magnetic conductive material, which helps to guide the heat field, improves the thermal efficiency, reduces energy loss, ensures that the heated air can be effectively introduced into the air duct, and improves the utilization rate of hot air.

[0008] Among them, the fan wheel is located in the wind deflector, and its rotation will generate strong airflow, which is heated when passing through the heated wind deflector and finally discharged from the front side of the machine head.

[0009] It should be noted that by limiting the air guide cover to have an air inlet side and an air outlet side on both sides of the axial direction, one side of the axial direction is the air inlet side, air flows in from the air inlet side and out from the air outlet side, in the axial direction, the caliber of the air guide cover on the air inlet side is smaller, that is, the first caliber on the air inlet side is smaller than the second caliber on the air outlet side, and the air guide cover as a whole is flared to facilitate the flow of air on the inner wall of the air guide cover and diffuse out.

[0010] It can be understood that the air conditioning equipment can mainly convert electrical energy into thermal energy and mechanical energy to generate hot air. In this scheme, by adjusting the relative position of the fan wheel and increasing the structure of the air guide cover, air will be blown to the air guide cover under the action of the fan wheel, and the air guide cover will be heated under the action of the electromagnetic heating device. The temperature of the air blown to the air guide cover can be increased, and at the same time, the air can be guided to the outside of the air conditioning equipment through the structural characteristics of the air guide cover, thereby providing warm air with a larger wind speed.

[0011] In some technical solutions, optionally, a gap exists between the electromagnetic heating device and the air guide cover.

[0012] By providing a gap between the electromagnetic heating device and the air guide cover, the high temperature of the air guide cover can be reduced to affect the temperature of the environment where the electromagnetic heating device is located, improving the safety of use, and at the same time, it is also beneficial to protect the electromagnetic heating device and prolong its service life.

[0013] In some technical solutions, optionally, the gap is greater than 5mm.

[0014] In this technical solution, by limiting the gap to be greater than 5mm, it can help the electromagnetic heating device to dissipate heat, avoid damaging internal components due to overheating, or affect the service life of the electromagnetic heating device. The gap allows air to circulate, which helps to disperse the heat generated from the electromagnetic heating device. It can be understood that in electromagnetic heating, the size of the gap will affect the distribution of the electromagnetic field, thereby affecting the heating efficiency and heating uniformity. If the gap is too small, it may cause local overheating, and if the gap is too large, it may reduce the heating efficiency.

[0015] It can be understood that by limiting the gap to be greater than 5mm, the heat dissipation of the electromagnetic heating device can be effectively guaranteed.

[0016] In some technical solutions, optionally, the gap is less than 30mm.

[0017] In this technical solution, by limiting the gap to be less than 30mm, it is beneficial to maintain the strength of the magnetic field generated by electromagnetic induction, thereby ensuring that the air guide cover can be effectively heated. If the gap is too large, the strength of the magnetic field will decrease, resulting in a decrease in heating efficiency. It can be understood that a smaller gap can enhance the coupling efficiency between the electromagnetic heating device and the air guide cover, making energy transfer more efficient. This helps to improve the overall heating performance of the warm air machine.

[0018] The holding gap is within a certain range, which helps to more accurately control the temperature of the air deflector, because the distribution and strength of the magnetic field have a direct impact on the heating temperature.

[0019] It can be understood that by limiting the gap to be less than 30mm, the coupling between the electromagnetic heating device and the air deflector can be effectively ensured.

[0020] In some technical solutions, optionally, a third caliber of the electromagnetic heating device corresponding to the air inlet side of the air deflector is less than a fourth caliber of the electromagnetic heating device corresponding to the air outlet side of the air deflector.

[0021] In this technical solution, the front and rear calibers of the electromagnetic heating device are limited. Specifically, the electromagnetic heating device has two ends corresponding to the air inlet side and the air outlet side of the air deflector, wherein the opening size of the end corresponding to the air inlet side is the third caliber, and the opening size of the end corresponding to the air outlet side is the fourth caliber. By limiting the fourth caliber of the electromagnetic heating device to be larger, the caliber change trend of the electromagnetic heating device as a whole is less different from the air deflector, that is, the gap between the electromagnetic heating device and the air deflector changes less, which ensures the heating effect of the electromagnetic heating device on the air deflector at different positions. The electromagnetic heating device and the air deflector are both large in front and small in back, which is more convenient to meet the use demand of large air volume and warm air.

[0022] In some technical solutions, optionally, the relative magnetic permeability of the air deflector is between 2 and 2000; and / or the electrical conductivity of the air deflector ranges from 5x10 5 S / m to 10 7 S / m.

[0023] In this technical solution, the material of the air deflector is limited, that is, the relative magnetic permeability of the air deflector is between 2 and 2000 and the electrical conductivity ranges from 5x10 5 S / m to 10 7 S / m, so that the air deflector can heat up under the action of the magnetic field generated by the electromagnetic heating device to achieve the heating effect on the air.

[0024] In some technical solutions, optionally, the air deflector is a rotating body, and in the plane passing through the axis of the air deflector, the profile of the air deflector is parallel to the profile of the electromagnetic heating device; or in the direction from the air inlet side of the air deflector to the air outlet side of the air deflector, the growth rate of the distance between the profile of the air deflector and the profile of the electromagnetic heating device is not less than 0.

[0025] In the technical solution, since the magnetic field distribution of the electromagnetic heating device is closely related to the profile shape thereof, the profile of the wind deflector is parallel to the profile of the electromagnetic heating device, which helps to form a more uniform magnetic field on the surface of the wind deflector, thereby improving the heating efficiency and uniformity. In addition, the structure of the rotating body ensures that the heat received by the wind deflector is uniformly distributed, reduces thermal stress and material fatigue caused by uneven heating, and facilitates smooth airflow, reduces air resistance, improves airflow efficiency, and enables the heated air to be more efficiently discharged.

[0026] Alternatively, the gap between the wind deflector and the electromagnetic heating device gradually increases, specifically, the wind deflector has an air inlet side and an air outlet side located on both sides in the axial direction, the air inlet side is on one side of the axial direction, air flows into the air inlet side and then flows out of the air outlet side, in the axial direction, specifically from the air inlet side of the wind deflector to the air outlet side of the wind deflector, the growth rate of the distance between the profile of the wind deflector and the profile of the electromagnetic heating device is not less than 0, that is, the gap between the two gradually increases or at least remains unchanged in the axial direction.

[0027] In some technical solutions, optionally, the motor is provided, and the drive shaft of the motor extends into the fan wheel and cooperates with the fan wheel.

[0028] In the technical solution, by providing the motor and extending the drive shaft of the motor into the fan wheel and cooperating with the fan wheel, the drive shaft can drive the fan wheel to rotate under the operation of the motor. It can be understood that the motor provides the required power, converts electrical energy into mechanical energy, and enables the fan wheel to rotate and generate airflow. The design of the motor needs to ensure sufficient torque to drive the fan wheel, and also needs to have good heat resistance.

[0029] It should be noted that the type of motor can be a direct current or alternating current motor, or even a brushless motor to improve efficiency and reduce maintenance; the power and speed of the motor should match the design of the fan wheel; the heat dissipation design of the motor should ensure that it does not overheat under long-term operation.

[0030] In some technical solutions, optionally, a wind channel is provided in the housing cover, and the fan wheel rotates, and air flows into the fan wheel through the wind channel.

[0031] In the technical solution, by providing the wind channel in the housing cover, the air inlet path of the fan wheel can be provided under the action of the wind channel, specifically, the outlet of the wind channel is arranged opposite to the air inlet side of the fan wheel, and for the entire air conditioning device, there can be one or more inlets of the wind channel, and the position of the inlet can be flexibly arranged to improve the air volume.

[0032] In some technical solutions, optionally, the electromagnetic heating device specifically comprises: a heating bracket, which is arranged correspondingly to the wind deflector and is arranged outside the wind deflector, and an electromagnetic coil is wound on the heating bracket.

[0033] In this technical solution, the electromagnetic heating device mainly includes a heating bracket, which is arranged corresponding to the wind deflector and is located outside the wind deflector. This helps to ensure the effective cooperation of the heating bracket and the wind deflector and provides a stable support structure. In addition, the heating bracket can be in the form of a disc, i.e., a coil disc. By winding an electromagnetic coil on the coil disc, an alternating magnetic field is generated when the electromagnetic coil is energized, enabling the wind deflector to achieve electromagnetic induction heating, thereby providing an efficient way for air heating.

[0034] In some technical solutions, optionally, it further includes a heat insulation bracket located outside the wind deflector; and the wind deflector is arranged on the heat insulation bracket.

[0035] In this technical solution, the heat insulation bracket is arranged outside the wind deflector. The arrangement of the heat insulation bracket can isolate the wind deflector and the electromagnetic heating device to some extent, reducing heat conduction to the wind deflector, thereby reducing the temperature of the wind deflector and improving the safety of use. In addition, the heat insulation bracket provides additional support and stability for the wind deflector, helping to maintain the position stability of the wind deflector, reduce vibration and friction, and improve the reliability of the entire system.

[0036] By isolating and stabilizing the wind deflector, it also helps to improve the working efficiency of the electromagnetic heating device, ensuring that the heated air can smoothly enter the air duct and then be pushed out by the fan.

[0037] Overall, the arrangement of the heat insulation bracket in this air conditioning device helps to improve the stability and safety of the system, while also being beneficial to improving the heating efficiency and ensuring the normal operation of the entire system.

[0038] In some technical solutions, optionally, the shell cover includes a detachably connected front mesh cover and a rear mesh cover, and the front mesh cover and the rear mesh cover are connected to form a containing cavity accommodating the electromagnetic heating device, the wind deflector, and the fan; and a first bearing is arranged on the front mesh cover for the driving shaft to pass through.

[0039] In this technical solution, the shell cover includes a detachably connected front mesh cover and a rear mesh cover, and the front mesh cover and the rear mesh cover are connected to form a containing cavity accommodating the electromagnetic heating device, the wind deflector, and the fan. A first bearing is arranged on the front mesh cover for the driving shaft to pass through. The detachable connection of the front mesh cover and the rear mesh cover facilitates the maintenance and cleaning of the internal components, making maintenance more convenient. This is very beneficial for the daily maintenance and care of the equipment.

[0040] The containing cavity formed by the connection of the front mesh cover and the rear mesh cover provides a suitable space to accommodate the electromagnetic heating device, the wind deflector, the fan, and the motor, so that these internal components can be effectively installed and fixed.

[0041] It should be noted that the front screen cover is provided with a first bearing for the driving shaft to pass through, which helps to support and fix the driving shaft, ensures the stable operation of the driving shaft, and reduces the vibration and friction caused by the movement of the driving shaft.

[0042] In general, the design of the shell cover improves the maintenance convenience of the equipment and the installation stability of the internal components, which is conducive to the use and maintenance of the entire system.

[0043] In some technical solutions, optionally, on the axial section of the air guide cover, at least part of the profile of the air guide cover is parabolic; and / or on the axial section of the electromagnetic heating device, at least part of the profile of the electromagnetic heating device is parabolic.

[0044] In this technical solution, by limiting the waist line shape of at least one of the air guide cover and the electromagnetic heating device, i.e., on the axial section of the air guide cover, part or all of the profile of the air guide cover is parabolic, the air resistance of the air flowing along the inner wall of the air guide cover can be reduced, or on the axial section of the electromagnetic heating device, part or all of the profile of the electromagnetic heating device is parabolic, so that the heating effect of the electromagnetic heating device on the air guide cover is more uniform.

[0057] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present application, the embodiments of the present application are further described in detail below in combination with the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0058] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, embodiments of the present application can also be implemented in other ways different from those described herein, therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0059] The following description refers to the accompanying drawings. Figures 1 to 5 Some embodiments according to the present application are described.

[0060] As Figure 1 and Figure 2As shown, the air conditioning device 100 proposed in this embodiment mainly comprises a shell cover 102, an electromagnetic heating device 104, an air guide cover 106 and a fan wheel 108 arranged in the shell cover 102. Specifically, the shell cover 102 provides a solid protective housing for the air conditioning device 100, which not only protects the internal structure from damage, but also plays a role in heat insulation and insulation to ensure safety when used by users. Specifically, the electromagnetic coil can be used as the electromagnetic heating device 104, and the material of the air guide cover 106 is a magnetic conductive material. By using the electromagnetic coil as the electromagnetic heating device 104, electromagnetic induction heating can be achieved, which has the advantages of uniform heating, fast response, etc., which is conducive to improving the heating efficiency and controlling the heating temperature. In addition, the air guide cover 106 adopts a magnetic conductive material, which helps to guide the heat field, improve the thermal efficiency, reduce energy loss, and ensure that the heated air can be effectively introduced into the air duct, improving the utilization rate of hot air.

[0061] Wherein, the limiting air guide cover has an air inlet side and an air outlet side located on both sides of the axial direction, the axial side is the air inlet side, the air flows into the air inlet side and then flows out of the air outlet side, in the axial direction, the caliber of the air guide cover at the air inlet side is smaller, that is, the first caliber 1072 at the air inlet side is smaller than the second caliber 1074 at the air outlet side, and the air guide cover as a whole is in the form of an expanding mouth, so as to facilitate the flow of air on the inner wall of the air guide cover and diffuse and discharge.

[0062] Wherein, as shown Figure 3 The fan wheel 108 is located in the air guide cover 106, and its rotation will generate strong air flow, which is heated when passing through the heated air guide cover 106 and finally discharged from the front side of the machine head.

[0063] It can be understood that the air conditioning device 100 mainly converts electrical energy into heat energy and mechanical energy to generate hot air. In this scheme, by adjusting the relative position of the fan wheel 108 and increasing the structure of the air guide cover 106, the air will be blown to the air guide cover 106 under the action of the fan wheel 108, and the air guide cover 106 will be heated under the action of the electromagnetic heating device 104, which can increase the temperature of the air blown to the air guide cover 106. At the same time, through the structural characteristics of the air guide cover 106, the air can be guided to the outside of the air conditioning device 100, thereby providing warm air with a larger wind speed.

[0064] In some embodiments, optionally, a gap d is arranged between the electromagnetic heating device 104 and the air guide cover 106, which helps to reduce the temperature of the air guide cover 106, reduce the conduction of heat to the air guide cover 106, improve the safety of use, and also helps to protect the electromagnetic heating device 104 and prolong its service life.

[0065] In some embodiments, optionally, as shown Figure 4As shown, the limiting gap d is greater than 5 mm, which can help dissipate heat from the electromagnetic heating device 104, avoiding damage to internal components due to overheating or affecting the service life of the electromagnetic heating device 104. The gap allows air circulation, which helps to disperse the heat generated from the electromagnetic heating device 104. It can be understood that in electromagnetic heating, the size of the gap affects the distribution of the electromagnetic field, thereby affecting the heating efficiency and heating uniformity. Too small a gap can cause local overheating, and too large a gap can reduce heating efficiency.

[0066] It can be understood that by limiting the gap d to be greater than 5 mm, the heat dissipation of the electromagnetic heating device 104 can be effectively guaranteed.

[0067] In some embodiments, optionally, limiting the gap d to be less than 30 mm is beneficial to maintain the strength of the magnetic field generated by electromagnetic induction, thereby ensuring that the air deflector 106 can be effectively heated. If the gap is too large, the magnetic field strength will decrease, resulting in a decrease in heating efficiency. It can be understood that a smaller gap can enhance the coupling efficiency between the electromagnetic heating device 104 and the air deflector 106, making energy transfer more efficient. This helps to improve the overall heating performance of the air heater.

[0068] Keeping the gap within a certain range helps to more accurately control the temperature of the air deflector 106, as the distribution and strength of the magnetic field directly affect the heating temperature.

[0069] It can be understood that by limiting the gap d to be less than 30 mm, the coupling between the electromagnetic heating device 104 and the air deflector 106 can be effectively guaranteed.

[0070] In some embodiments, optionally, the front and rear diameters of the electromagnetic heating device 104 are limited. Specifically, the electromagnetic heating device 104 has two ends corresponding to the air inlet side and the air outlet side of the air deflector 106, wherein the opening size of the end corresponding to the air inlet side is a third diameter, and the opening size of the end corresponding to the air outlet side is a fourth diameter. By limiting the fourth diameter of the electromagnetic heating device 104 to be larger, the change trend of the overall diameter of the electromagnetic heating device 104 is less different from that of the air deflector 106, i.e., the gap between the electromagnetic heating device 104 and the air deflector 106 changes less, ensuring the heating effect of the electromagnetic heating device 104 on the air deflector 106 at different positions. The electromagnetic heating device 104 and the air deflector 106 are both large in front and small in back, which is more convenient to meet the use demand of large air volume of warm air.

[0071] In some embodiments, optionally, the material of the air deflector 106 is limited, i.e., the relative magnetic permeability of the air deflector 106 is between 2 and 2000, and the electrical conductivity range is 5x10 5 S / m to 10 7The distance between the air deflector 106 and the electromagnetic heating device 104 is between 0.5S and 2S, so that the air deflector 106 can be heated under the action of the magnetic field generated by the electromagnetic heating device 104, and the heating effect of the air is achieved.

[0072] In some embodiments, optionally, since the magnetic field distribution of the electromagnetic heating device 104 is closely related to the profile shape thereof, the profile of the air deflector 106 parallel to the profile of the electromagnetic heating device 104 helps to form a more uniform magnetic field on the surface of the air deflector 106, thereby improving the heating efficiency and uniformity. In addition, the structure of the rotating body ensures that the heat received by the air deflector 106 is uniformly distributed, reduces thermal stress and material fatigue caused by uneven heating, and at the same time facilitates smooth airflow, reduces wind resistance, improves airflow efficiency, and makes the heated air be sent out more efficiently.

[0073] Alternatively, in another specific embodiment, the gap between the air deflector 106 and the electromagnetic heating device 104 gradually increases, specifically, the air deflector 106 has an air inlet side and an air outlet side located on both sides of the axial direction, the air inlet side is on one side of the axial direction, and the air flows into the air deflector 106 from the air inlet side and flows out from the air outlet side. In the axial direction, specifically, from the air inlet side of the air deflector 106 to the air outlet side of the air deflector 106, the growth rate of the distance between the profile of the air deflector 106 and the profile of the electromagnetic heating device 104 is not less than 0, that is, the gap between the two gradually increases or at least remains unchanged in the axial direction.

[0074] In some embodiments, optionally, by providing the motor 110 and extending the driving shaft of the motor 110 into the fan wheel 108 and cooperating with the fan wheel 108, the driving shaft can be controlled to rotate the fan wheel 108 together under the operation of the motor 110. It can be understood that the motor 110 provides the required power, converts electrical energy into mechanical energy, so that the fan wheel 108 can rotate and generate airflow. The design of the motor 110 needs to ensure sufficient torque to drive the fan wheel 108, and at the same time has good heat resistance.

[0075] In addition, the motor support 1104 is also provided, the motor 110 is arranged on the motor support 1104, and the motor support 1104 is detachably connected with the front mesh cover 1022 or the rear mesh cover 1024.

[0076] It should be noted that the motor 110 can be a direct current or alternating current motor 110, or even a brushless motor 110 to improve efficiency and reduce maintenance; the power and speed of the motor 110 are matched with the design of the fan wheel 108; the heat dissipation design of the motor 110 needs to ensure that it will not overheat under long-time operation.

[0077] In some embodiments, optionally, a wind channel is arranged in the housing cover 102, and the air inlet path of the wind wheel can be provided under the action of the wind channel. Specifically, the outlet of the wind channel is arranged opposite to the air inlet side of the wind wheel. For the entire air conditioning device, there can be one or more inlets of the wind channel, and the position of the inlet can be flexibly arranged in order to improve the air volume.

[0078] In some embodiments, optionally, as shown in Figure 4 The electromagnetic heating device 104 mainly includes a heating support 1042. The heating support 1042 is arranged corresponding to the air guide cover 106 and is arranged outside the air guide cover 106. This helps to ensure the effective cooperation of the heating support 1042 and the air guide cover 106 and provides a stable support structure. In addition, the heating support can be in the form of a disc, i.e., a coil disc. By winding an electromagnetic coil on the coil disc, an alternating magnetic field is generated after the electromagnetic coil is energized, so that the air guide cover 106 realizes electromagnetic induction heating, thereby providing an efficient way for air heating.

[0079] In some embodiments, optionally, as shown in Figure 4 The heat insulation support 1062 is arranged outside the air guide cover 106. The arrangement of the heat insulation support 1062 can isolate the air guide cover 106 and the electromagnetic heating device 104 to a certain extent, reduce the conduction of heat to the air guide cover 106, thereby reducing the temperature of the air guide cover 106 and improving the safety of use. In addition, the heat insulation support 1062 can provide additional support and stability for the air guide cover 106, which helps to keep the position of the air guide cover 106 stable, reduces vibration and friction, and improves the reliability of the entire system.

[0080] By isolating and stabilizing the air guide cover 106, the working efficiency of the electromagnetic heating device 104 is also improved, which ensures that the heated air can smoothly enter the wind channel and then be pushed out by the wind wheel 108.

[0081] In general, the arrangement of the heat insulation support 1062 helps to improve the stability and safety of the system and also improves the heating efficiency, thereby ensuring the normal operation of the entire system.

[0082] In some embodiments, optionally, the housing cover 102 includes a front mesh cover 1022 and a rear mesh cover 1024 which are detachably connected and form a containing cavity for accommodating the electromagnetic heating device 104, the air guide cover 106, and the wind wheel 108. The first bearing for the driving shaft to pass through is arranged on the front mesh cover 1022. The detachable connection of the front mesh cover 1022 and the rear mesh cover 1024 facilitates the maintenance and cleaning of the internal components, making the maintenance more convenient. This is very beneficial for the daily maintenance and care of the device.

[0083] The accommodating cavity formed by the connection of the front mesh cover 1022 and the rear mesh cover 1024 provides a suitable space to accommodate the electromagnetic heating device 104, the air guide cover 106, the air wheel 108 and the motor 110, so that these internal components can be effectively installed and fixed.

[0084] It should be noted that the front mesh cover 1022 is provided with a first bearing through which the driving shaft passes, which helps to support and fix the driving shaft, ensuring the stable operation of the driving shaft and reducing vibration and friction caused by the movement of the driving shaft.

[0085] In general, the design of the shell cover 102 improves the convenience of maintenance of the equipment and the stability of installation of the internal components, which is conducive to the use and maintenance of the entire system.

[0086] In some embodiments, the waistline shape of the air guide cover 106 is optionally limited, that is, in the cross section passing through the axis of the air guide cover 106, part or all of the profile of the air guide cover 106 is a parabola, which can reduce the air resistance when the air flows along the inner wall of the air guide cover 106, or the waistline shape of the electromagnetic heating device 104 is limited, that is, in the cross section passing through the axis of the electromagnetic heating device 104, part or all of the profile of the electromagnetic heating device 104 is a parabola, so that the heating effect of the electromagnetic heating device 104 on the air guide cover 106 is more uniform.
