Description

Heating device and cooking equipment

Technical Field

The invention relates to the technical field of household appliances, in particular to a heating device and cooking equipment.

Background

With the diversification of diets and the introduction of foreign cooking methods, ovens are becoming more common in the kitchens of people. Among other things, temperature uniformity within the oven is an important performance indicator for the oven. The existing oven usually uses an impeller to directly blow air through a heating pipe, the heated air flows into a cavity through an air outlet on a hot air cover, and flows back to a fan through an air return port on the hot air cover after flowing and heat exchanging in the cavity to form circulation. But the wind direction that fan and impeller formed is comparatively single, consequently after the cavity of heating pipe entering oven is crossed to wind, can cause the inhomogeneous phenomenon of temperature in the cavity, influences the use experience of oven.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art or the related art.

In view of this, a first aspect of embodiments of the present invention provides a heating apparatus.

A second aspect of embodiments of the present invention provides a cooking apparatus.

In order to achieve the above object, an embodiment of a first aspect of the present invention provides a heating apparatus including: an impeller; the air outlet structure is sleeved outside the impeller, airflow formed by rotation of the impeller can flow to the air outlet structure, the air outlet structure is provided with a plurality of air outlets, and the air outlet directions of at least two air outlets are different; the heating element is wound outside the air outlet structure along the circumferential direction of the impeller and flows out through the heating element through the air outlet; wherein, the air-out structure can take place to rotate.

According to an embodiment of the first aspect of the present invention, a heating device is provided, which includes an impeller, an air outlet structure, and a heating element. Wherein the impeller can form an air flow during rotation. The air outlet structure is sleeved outside the impeller, so that air flow formed when the impeller rotates can be limited in the air outlet structure. Because the air outlet structure is provided with the air outlets, the air flow formed by the impeller is inevitably discharged from the air outlets. On the basis, the heating elements are arranged around the outer impeller of the air outlet structure in the circumferential direction, and air flow discharged from the air outlet can be heated by the heating elements to become high-temperature air flow when passing through the heating elements.

It can be understood that the air outlet directions of the air outlets are different, and the directions of the air flows discharged from the air outlets are different inevitably, so that the air flows formed by the impeller finally form air flows in different directions. Further, the air-out structure can take place to rotate, therefore a plurality of air outlets of air-out structure also can take place to rotate because of the rotation of air-out structure, it is very obvious, from the direction of a plurality of air outlet combustion gas flows, also can be driven because of the rotation of air-out structure and take place to rotate, finally make the rotation of air outlet combustion gas flow direction following the air-out structure, thereby make all around directions of impeller and air-out structure can both be even blow by the air current, make air current distribution more even, can not produce the dead angle.

It can be understood that, because the air outlet structure can rotate, the air current discharged from the air outlet of the air outlet structure can enable the air current to pass through different positions of the heating element. By the aid of the heating device, the temperature of different positions of the heating device can be kept consistent, and the phenomenon that the temperature is too high due to the fact that no air flow blows through some parts is avoided. In addition, the air flow passing through the heating element can be ensured, the raised temperature is more consistent, and the temperatures of the wind discharged from the heating device in different directions are basically the same, so that the uniformity of the temperature in the equipment can be ensured.

It should be noted that the rotation of the air outlet structure can be driven to rotate by having a certain transmission mechanism with the impeller, and the air flow generated by the impeller can also drive the air outlet structure to rotate, so that the structural form of the air outlet structure can be more various. Generally, the shaft of the air outlet structure may be shared with the impeller, and when the air flow is discharged from the air outlet of the air outlet structure, the air flow drives the air outlet structure to rotate around the shaft of the impeller. In addition, for the heating device arranged in a cavity structure, the air outlet structure can also be arranged on the cavity or the shell, and the air outlet structure is not mechanically connected with the impeller. In this way, the impeller and the air outlet structure can be relatively independent.

Detailed Description

In order that the above objects, features and advantages of the embodiments of the present invention can be more clearly understood, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, embodiments of the present invention may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.

Some embodiments according to the invention are described below with reference to fig. 1 to 15.

Example one

As shown in fig. 1 to 4, the heating apparatus 100 according to the present embodiment: including impeller 102, air-out structure 104 and heating element 116. Wherein the impeller 102 creates an airflow by rotating. The air outlet structure 104 is sleeved outside the impeller 102, and an air flow formed when the impeller 102 rotates is limited in the air outlet structure 104. The air outlet structure 104 is provided with a plurality of air outlets 106, and the air flow formed by the impeller 102 is inevitably discharged from the plurality of air outlets 106. Furthermore, the heating member 116 is disposed around the outer impeller 102 of the air outlet structure 104, and the air flow discharged from the air outlet 106 is heated by the heating member 116 to become a high-temperature air flow when passing through the heating member 116.

It can be appreciated that, because the air outlet structure 104 can rotate, the air flow discharged from the air outlet 106 of the air outlet structure 104 can allow the air flow to pass through different positions of the heating element 116. This allows the temperature to be maintained consistently at different locations of the heating element 116, rather than being too high due to lack of air flow over some parts. In addition, it is ensured that the temperature of the air passing through the heating element 116 is increased more uniformly, and finally, the temperature of the air discharged from the heating device 100 in different directions is substantially the same, so that the temperature uniformity in the equipment can be ensured.

It can be understood that the air outlet directions of the air outlets 106 are different, and the directions of the air flows discharged from the air outlets 106 are necessarily different, so that the air flows formed by the impeller 102 finally form a plurality of air flows with different directions. Further, the air-out structure 104 can rotate under the effect of the air current that forms when impeller 102 rotates, and therefore a plurality of air outlets 106 of air-out structure 104 also can rotate because of the rotation of air-out structure 104, and it is obvious that the direction of the air current from a plurality of air outlets 106 also can be driven to rotate because of the rotation of air-out structure 104, and finally the air current direction of air outlet 106 exhaust rotates along with the rotation of air-out structure 104, thereby all around directions of impeller 102 and air-out structure 104 can both be blown by the air current evenly, make the air current distribute more evenly, can not produce the dead angle. Fig. 5 to 7 are schematic structural views of the impeller 102, and fig. 8 to 10 are schematic structural views of the air outlet structure 104.

It should be noted that the rotation of the air outlet structure 104 is not driven to rotate by a certain transmission mechanism between the air outlet structure and the impeller 102, but the air flow generated by the impeller 102 drives the air outlet structure 104 to rotate, so that the structural form of the air outlet structure 104 may be more various. Generally, the axis of the wind outlet structure 104 may be shared with the impeller 102, and when the airflow is discharged from the wind outlet 106 of the wind outlet structure 104, the airflow drives the wind outlet structure 104 to rotate around the axis of the impeller 102. In addition, for heating device 100 disposed in a cavity structure, air outlet structure 104 may also be disposed on cavity or housing 202, and there is no mechanical connection between air outlet structure 104 and impeller 102. In this way, the impeller 102 and the wind outlet structure 104 can be relatively independent.

Example two

Further, the impeller 102 is a centrifugal impeller, and the airflow generated when the impeller 102 rotates flows in a radial direction of the impeller 102. The air outlet structure 104 is disposed outside the impeller 102 along the circumferential direction of the impeller 102, and the air flow flowing in the radial direction of the impeller 102 is blown to the portion of the air outlet structure 104 relative to the circumferential direction of the impeller 102. Since the air outlet structure 104 is provided with a plurality of air outlets 106 at a portion corresponding to the circumferential direction of the impeller 102, it is obvious that the air flow is finally discharged from the air outlets 106 on the air outlet structure 104 at the circumferential direction of the impeller 102. It can be understood that when the wind outlet structure 104 rotates, the wind outlet 106 also rotates, and the direction of the airflow discharged from the wind outlet 106 also rotates together with the rotation of the wind outlet 106, so that the airflow discharged from the wind outlet structure 104 can be blown to any direction of the circumference of the impeller 102.

Further, the wind outlet structure 104 includes a rotating shaft 122 rotatable around the rotating shaft, and the wind outlet direction of the wind outlet 106 is different from the radial direction of the rotating shaft 122, so that when the airflow is discharged from the wind outlet 106, besides a radial direction component, there must be a circumferential direction relative to the rotating shaft 122 of the wind outlet structure 104. The air current along the circumference direction exhaust can form a reaction force to air-out structure 104, promotes air-out structure 104 and rotates. It can be understood that the larger the flow rate of the airflow generated by the rotation of the impeller 102, the stronger the force of the airflow to rotate the wind outlet structure 104. In addition, the faster the flow velocity of the airflow generated by the rotation of the impeller 102, the faster the airflow drives the air outlet structure 104 to rotate.

EXAMPLE III

It can be appreciated that since the air outlet structure 104 can rotate, the air flow discharged from the air outlet 106 of the air outlet structure 104 can pass through the heating element 116 at different positions. This allows the temperature to be maintained consistently at different locations of the heating element 116, rather than being too high due to lack of air flow over some parts. In addition, it is also ensured that the temperature rise of the air flow passing through the heating element 116 is more uniform, and finally the temperature of the wind discharged from the heating device 100 in different directions is basically the same, so that the temperature uniformity in the equipment can be ensured.

It should be noted that the rotation of the air outlet structure 104 is not driven to rotate by a certain transmission mechanism between the air outlet structure and the impeller 102, but the air flow generated by the impeller 102 drives the air outlet structure 104 to rotate, so that the structural form of the air outlet structure 104 may be more various. Generally, the axis of the wind outlet structure 104 may be shared with the impeller 102, and when the airflow is discharged from the wind outlet 106 of the wind outlet structure 104, the airflow drives the wind outlet structure 104 to rotate around the axis of the impeller 102. In addition, for heating device 100 disposed in a cavity structure, air outlet structure 104 may also be disposed on cavity or housing 202, and there is no mechanical connection between air outlet structure 104 and impeller 102. In this way, the impeller 102 and the air outlet structure 104 can be relatively independent.

Further, the impeller 102 is a centrifugal impeller, and an air flow generated when the impeller 102 rotates flows in a radial direction of the impeller 102. The air outlet structure 104 is disposed outside the impeller 102 along the circumferential direction of the impeller 102, and the air flow flowing in the radial direction of the impeller 102 is blown to the portion of the air outlet structure 104 relative to the circumferential direction of the impeller 102. Since the air outlet structure 104 is provided with a plurality of air outlets 106 at a portion opposite to the circumferential direction of the impeller 102, it is obvious that the air flow is finally discharged from the air outlets 106 on the air outlet structure 104 at the circumferential direction of the impeller 102. It can be understood that when the wind outlet structure 104 rotates, the wind outlet 106 also rotates, and the direction of the airflow discharged from the wind outlet 106 also rotates together with the rotation of the wind outlet 106, so that the airflow discharged from the wind outlet structure 104 can be blown to any direction of the circumference of the impeller 102.

Further, the air outlet direction of the air outlet 106 is different from the radial direction of the rotation shaft 122 of the air outlet structure 104, so that when the air flow is discharged from the air outlet 106, besides a radial direction component, there is inevitably a circumferential direction relative to the rotation shaft 122 of the air outlet structure 104. The air current along the circumference direction exhaust can form a reaction force to air-out structure 104, promotes air-out structure 104 and rotates. It can be understood that the larger the flow rate of the airflow generated by the rotation of the impeller 102, the stronger the force of the airflow to rotate the wind outlet structure 104. In addition, the faster the flow velocity of the airflow generated by the rotation of the impeller 102, the faster the airflow drives the air outlet structure 104 to rotate.

Further, the plurality of air outlets 106 are uniformly arranged around the axis of the rotating shaft 122, so that the direction of the air flow discharged from the air outlet structure 104 can be uniformly distributed along the direction of the rotating shaft 122. Because the air current can form a reverse thrust to air-out structure 104 simultaneously when discharging from air outlet 106, evenly distributed's air outlet 106 for the reverse thrust that a plurality of air outlet 106 exhansts air current formed is also more even to air-out structure 104, and the rotation of air-out structure 104 can be more steady, can not produce periodic vibration because of the reverse thrust distributes unevenly. In addition, the air outlets 106 are uniformly distributed along the circumferential direction, so that the air flow discharged from the air outlet structure 104 is also uniformly distributed.

Example four

As shown in fig. 1 to 4, the heating apparatus 100 of the present embodiment: including impeller 102, air-out structure 104 and heating element 116. Wherein the impeller 102 creates an airflow by rotating. The air outlet structure 104 is sleeved outside the impeller 102, and an air flow formed when the impeller 102 rotates is limited in the air outlet structure 104. The air outlet structure 104 is provided with a plurality of air outlets 106, and the air flow formed by the impeller 102 is inevitably discharged from the plurality of air outlets 106. Furthermore, the heating member 116 is disposed around the outer impeller 102 of the air outlet structure 104, and the air flow discharged from the air outlet 106 is heated by the heating member 116 to become a high-temperature air flow when passing through the heating member 116.

It can be appreciated that since the air outlet structure 104 can rotate, the air flow discharged from the air outlet 106 of the air outlet structure 104 can pass through the heating element 116 at different positions. This allows the temperature to be maintained consistently at different locations of the heating element 116, rather than being too high due to lack of air flow over some parts. In addition, it is ensured that the temperature of the air passing through the heating element 116 is increased more uniformly, and finally, the temperature of the air discharged from the heating device 100 in different directions is substantially the same, so that the temperature uniformity in the equipment can be ensured.

It can be understood that the air outlet directions of the air outlets 106 are different, and the directions of the air flows exhausted from the air outlets 106 are necessarily different, so that the air flows formed by the impeller 102 finally form a plurality of air flows with different directions. Further, the air-out structure 104 can rotate under the effect of the air current that forms when impeller 102 rotates, and therefore a plurality of air outlets 106 of air-out structure 104 also can rotate because of the rotation of air-out structure 104, and it is obvious that the direction of the air current from a plurality of air outlets 106 also can be driven to rotate because of the rotation of air-out structure 104, and finally the air current direction of air outlet 106 exhaust rotates along with the rotation of air-out structure 104, thereby all around directions of impeller 102 and air-out structure 104 can both be blown by the air current evenly, make the air current distribute more evenly, can not produce the dead angle. Fig. 5 to 7 are schematic structural views of the impeller 102, and fig. 8 to 10 are schematic structural views of the air outlet structure 104.

Further, the plurality of air outlets 106 are uniformly arranged around the axis of the rotating shaft 122 on the end surface of the rotating shaft 122, so that the direction of the air flow discharged from the air outlet structure 104 can be uniformly distributed along the direction of the rotating shaft 122. Because the air current can form a reverse thrust to air-out structure 104 simultaneously when discharging from air outlet 106, evenly distributed's air outlet 106 for the reverse thrust that a plurality of air outlet 106 exhansts air current formed is also more even to air-out structure 104, and the rotation of air-out structure 104 can be more steady, can not produce periodic vibration because of the reverse thrust distributes unevenly. In addition, the air outlets 106 are uniformly distributed along the circumferential direction, so that the air flow discharged from the air outlet structure 104 is also uniformly distributed.

Further, as shown in fig. 11 to 14, an air outlet housing 108 is provided outside the air outlet structure 104, and the impeller 102 and the air outlet structure 104 are arranged inside the air outlet housing 108. The outlet housing 108 is provided with an outlet hole 110 along the circumferential direction and an inlet hole 112 opposite to the impeller 102. It will be appreciated that if the air outlet 110 and the air inlet 112 are not provided, the air flow generated by the rotation of the impeller 102 and the air outlet structure 104 will be confined within the air outlet housing 108. The wind outlet housing 108 is provided with wind outlet holes 110 and wind inlet holes 112, and the air will enter the wind outlet housing 108 through the wind inlet holes 112, and will be discharged from the wind outlet 106 of the wind outlet structure 104 through the rotation of the impeller 102, and finally will be discharged out of the wind outlet housing 108 along the wind outlet holes 110 arranged in the circumferential direction. The wind outlet housing 108 is arranged to allow airflow to enter through wind inlet openings 112 arranged opposite to the impeller 102 and then to exit through wind outlet openings 110 arranged at the periphery. Through setting up out fan housing 108, can keep apart rotatable structure and other structures in the equipment to prevent that other structures in the equipment from producing the influence to the rotation of air-out structure 104. In addition, due to the rotation of the air outlet structure 104, the flow rate of the air flow discharged from each air outlet 110 of the air outlet housing 108 is relatively uniform.

Further, the wind outlet housing 108 includes an end plate 114, the end plate 114 is provided with wind inlet holes 112, and the air enters from the wind inlet holes 112 on the end plate 114. And is discharged from the air outlet 110 of the side plate connected with the periphery of the end plate 114. A certain connection angle may be formed between the side plate and the end plate 114, and the difference in connection angle may have a certain influence on the air outlet direction of the air outlet 110.

EXAMPLE five

As shown in fig. 1 to 4, the heating apparatus 100 according to the present embodiment: including impeller 102, air-out structure 104 and heating element 116. Wherein the impeller 102 creates an airflow by rotating. The air outlet structure 104 is sleeved outside the impeller 102, and an air flow formed when the impeller 102 rotates is limited in the air outlet structure 104. The air outlet structure 104 is provided with a plurality of air outlets 106, and the air flow formed by the impeller 102 is inevitably discharged from the plurality of air outlets 106. Furthermore, a heating element 116 is disposed around the outer impeller 102 of the air outlet structure 104, and the air flow discharged from the air outlet 106 is heated by the heating element 116 to become a high-temperature air flow when passing through the heating element 116.

Generally, the axis of the wind outlet structure 104 may be shared with the impeller 102, and when the airflow is discharged from the wind outlet 106 of the wind outlet structure 104, the airflow drives the wind outlet structure 104 to rotate around the axis of the impeller 102. Furthermore, for heating device 100 disposed within a cavity structure, air outlet structure 104 may also be disposed on cavity or housing 202 without mechanical connection between air outlet structure 104 and impeller 102. In this way, the impeller 102 and the wind outlet structure 104 can be relatively independent.

Further, the impeller 102 is a centrifugal impeller, and an air flow generated when the impeller 102 rotates flows in a radial direction of the impeller 102.

It can be understood that when the air outlet structure 104 rotates, the air outlet 106 also rotates together, and the direction of the air flow discharged from the air outlet 106 also rotates together with the rotation of the air outlet 106, so that the air flow discharged from the air outlet structure 104 can be blown to any direction in the circumferential direction of the impeller 102.

Further, as shown in fig. 11 to 14, an air outlet housing 108 is provided outside the air outlet structure 104, and the impeller 102 and the air outlet structure 104 are arranged inside the air outlet housing 108. An air outlet hole 110 is formed in the air outlet housing 108 along the circumferential direction, and an air inlet hole 112 is formed opposite to the impeller 102. It will be appreciated that if the air outlet 110 and the air inlet 112 are not provided, the air flow generated by the rotation of the impeller 102 and the air outlet structure 104 will be confined within the air outlet housing 108. The wind outlet housing 108 is provided with wind outlet holes 110 and wind inlet holes 112, and the air will enter the wind outlet housing 108 through the wind inlet holes 112, and will be discharged from the wind outlet 106 of the wind outlet structure 104 through the rotation of the impeller 102, and finally will be discharged out of the wind outlet housing 108 along the wind outlet holes 110 arranged in the circumferential direction. The wind outlet housing 108 is arranged to allow airflow to enter through wind inlet openings 112 arranged opposite to the impeller 102 and then to exit through wind outlet openings 110 arranged at the periphery. Through setting up out fan housing 108, can keep apart rotatable structure and other structures in the equipment to prevent that other structures in the equipment from producing the influence to the rotation of air-out structure 104. In addition, due to the rotation of the air outlet structure 104, the flow rate of the air flow discharged from each air outlet 110 of the air outlet housing 108 is relatively uniform.

Further, the exhaust hood 108 includes an end plate 114, the end plate 114 is provided with air inlet holes 112, and air enters from the air inlet holes 112 on the end plate 114. And is discharged from the air outlet 110 of the side plate connected with the periphery of the end plate 114. A certain connection angle may be formed between the side plate and the end plate 114, and the difference in connection angle may have a certain influence on the air outlet direction of the air outlet 110.

EXAMPLE six

As shown in fig. 1 to 4, the heating apparatus 100 according to the present embodiment: including impeller 102, air-out structure 104 and heating element 116. Wherein the impeller 102 creates an airflow by rotating. The air outlet structure 104 is sleeved outside the impeller 102, and the air flow formed when the impeller 102 rotates is limited in the air outlet structure 104. The air outlet structure 104 is provided with a plurality of air outlets 106, and the air flow formed by the impeller 102 is inevitably discharged from the plurality of air outlets 106.

It can be appreciated that, because the air outlet structure 104 can rotate, the air flow discharged from the air outlet 106 of the air outlet structure 104 can allow the air flow to pass through different positions of the heating element 116.

In addition, it is ensured that the temperature of the air passing through the heating element 116 is increased more uniformly, and finally, the temperature of the air discharged from the heating device 100 in different directions is substantially the same, so that the temperature uniformity in the equipment can be ensured. It can be understood that the air outlet directions of the air outlets 106 are different, and the directions of the air flows discharged from the air outlets 106 are necessarily different, so that the air flows formed by the impeller 102 finally form a plurality of air flows with different directions. Further, the air-out structure 104 can rotate under the effect of the air current that forms when impeller 102 rotates, and therefore a plurality of air outlets 106 of air-out structure 104 also can rotate because of the rotation of air-out structure 104, and it is obvious that the direction of the air current from a plurality of air outlets 106 also can be driven to rotate because of the rotation of air-out structure 104, and finally the air current direction of air outlet 106 exhaust rotates along with the rotation of air-out structure 104, thereby all around directions of impeller 102 and air-out structure 104 can both be blown by the air current evenly, make the air current distribute more evenly, can not produce the dead angle. Fig. 5 to 7 are schematic structural views of the impeller 102, and fig. 8 to 10 are schematic structural views of the air outlet structure 104.

Further, the impeller 102 is a centrifugal impeller, and an air flow generated when the impeller 102 rotates flows in a radial direction of the impeller 102. The air outlet structure 104 is disposed outside the impeller 102 along the circumferential direction of the impeller 102, and the air flow flowing in the radial direction of the impeller 102 is blown to the portion of the air outlet structure 104 relative to the circumferential direction of the impeller 102. Since the air outlet structure 104 is provided with a plurality of air outlets 106 at a portion corresponding to the circumferential direction of the impeller 102, it is obvious that the air flow is finally discharged from the air outlets 106 on the air outlet structure 104 at the circumferential direction of the impeller 102. It can be understood that when the wind outlet structure 104 rotates, the wind outlet 106 also rotates, and the direction of the airflow discharged from the wind outlet 106 also rotates together with the rotation of the wind outlet 106, so that the airflow discharged from the wind outlet structure 104 can be blown to any direction of the circumference of the impeller 102.

Furthermore, the heating member 116 is disposed around the outer impeller 102 of the air outlet structure 104, and the air flow discharged from the air outlet 106 is heated by the heating member 116 to become a high-temperature air flow when passing through the heating member 116. It can be appreciated that because the air outlet structure 104 can rotate, the air flow discharged from the air outlet 106 of the air outlet structure 104 can allow the air flow to pass through different positions of the heating element 116. This allows the temperature to be maintained consistently at different locations of the heating element 116, rather than being too high due to lack of air flow over some parts. In addition, it is ensured that the temperature of the air passing through the heating element 116 is increased more uniformly, and finally, the temperature of the air discharged from the heating device 100 in different directions is substantially the same, so that the temperature uniformity in the equipment can be ensured.

Further, the heating device 100 further includes a motor 118, and a rotating shaft 122 of the impeller 102 is drivingly connected to the motor 118, so that the motor 118 can drive the impeller 102 to rotate. Since the impeller 102 is rotated by the motor 118, and the motor 118 can change the rotation speed by setting the phase current of the motor 118, the rotation speed of the impeller 102 can be conveniently adjusted by the motor 118 to form airflows with different air volumes.

Further, the heating device 100 includes a bearing 120, the air-out structure 104 is sleeved on the bearing 120, and the bearing 120 is sleeved on a driving shaft of the motor 118, so that when the motor 118 drives the impeller 102 to rotate, due to the function of the bearing 120, the air-out structure 104 is not driven to rotate by the driving shaft of the motor 118, but is driven to rotate only by the airflow generated by the impeller 102.

In addition, since the air outlet structure 104 is sleeved on the driving shaft of the motor 118 through the bearing 120, and the rotating shaft 122 of the motor 118 is in transmission connection with the motor 118, it can be understood that the impeller 102 is coaxial with the air outlet structure 104.

Further, the heating device 100 further includes a fixing plate 124, the fixing plate 124 is disposed at one side of the air outlet structure 104, wherein the rotating shaft 122 of the air outlet structure 104 is disposed on the fixing plate 124. Through setting up fixed plate 124, provide a stable fixed plate 124 for air-out structure 104, be convenient for carry out fixed connection with equipment.
