[0002] At present, in the relevant technology, a cover body is provided in the heating device, and an air outlet is provided on the cover body. The airflow generated inside the heating device will flow out of the heating device through the air outlet, so as to heat the surrounding environment. However, since the opening size of the air outlet on the cover body is fixed, the air outlet pattern at the air outlet is fixed, resulting in a single air outlet pattern of the heating device, which causes inconvenience to the user. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] To this end, a first aspect of the utility model provides a heating device.

[0005] A second aspect of the present invention provides another heating device.

[0006] In view of this, the first aspect of the utility model provides a heating device, including a shell, a first cover body, a heating component, a second cover body and a dial button, the shell having an air inlet and a cavity, the air inlet is connected to the cavity, the first cover body is located on the side of the cavity away from the air inlet, the first cover body is provided with a first air outlet, the heating component is arranged in the cavity, the second cover body can rotate relative to the first cover body, the second cover body is provided with a second air outlet, the dial button is connected to the second cover body, and is located outside the second air outlet; wherein, when the second cover body is rotated to a first position relative to the first cover body, the first air outlet is connected to the second air outlet; when the second cover body is rotated to a second position relative to the first cover body, the first air outlet is disconnected from the second air outlet.

[0007] A heating device provided in the present application includes a shell, a first cover, a heating component, a second cover and a dial button. The shell has an air inlet and a cavity. The air inlet is connected to the cavity to facilitate gas to enter the cavity through the air inlet, thereby improving the air intake efficiency of the heating device. The first cover is located on the side of the cavity away from the air inlet. The first cover is provided with a first air outlet. The cavity of the heating device can be protected by the first cover to prevent pollutants from entering the heating device. At the same time, the air outlet efficiency of the heating device can be improved by providing the first air outlet. By arranging the heating component in the cavity, when the heating device is working, the external gas of the heating device can enter the cavity through the air inlet, the heating device can heat the gas through the heating component, and the heated gas can flow out of the heating device through the first air outlet on the first cover, which can increase the ambient temperature, provide warm airflow to the user, and enhance the experience of the heating device.

[0008] The second cover body can rotate relative to the first cover body, and the second cover body is provided with a second air outlet. The button is connected to the second cover body and is located outside the second air outlet; wherein, when the second cover body is rotated to a first position relative to the first cover body, the first air outlet is connected to the second air outlet, so that the airflow in the cavity can be discharged from the heating device through the first air outlet, thereby improving the exhaust efficiency of the heating device; when the second cover body is rotated to a second position relative to the first cover body, the first air outlet is disconnected from the second air outlet, thereby reducing the probability of the airflow in the cavity flowing out of the heating device through the first air outlet, and avoiding the airflow directly flowing out of the heating device through the first air outlet, so that the user can control whether the heating device exhausts gas through the first air outlet by manually operating the button, thereby improving the flexibility of the heating device. Furthermore, when the second cover body is rotated to the second position relative to the first cover body, the first air outlet and the second air outlet can be arranged alternately, the first cover body can be covered on the second air outlet, and the second cover body can be covered on the side of the first air outlet close to the cavity, so as to avoid the airflow directly passing through the second air outlet and the first air outlet and then flowing out of the heating device. Part of the airflow can be made to flow out of the heating device through the gap between the first cover body and the second cover body, thereby slowing down the airflow velocity, facilitating user use, and enriching the functionality of the heating device.

[0009] The user can operate the dial button to rotate the second cover body relative to the first cover body, and by setting the first air outlet to be connected with the second air outlet when the second cover body is rotated to the first position relative to the first cover body, and the first air outlet to be disconnected from the second air outlet when the second cover body is rotated to the second position relative to the first cover body, the user can manually operate the dial button to control whether the heating device exhausts gas through the first air outlet, enrich the exhaust mode of the heating device, and improve the flexibility of the heating device. Furthermore, the user can control the area of ​​the first air outlet covered by the second cover body by rotating the second cover body, thereby controlling the exhaust area of ​​the first air outlet. When the second cover body is rotated to the second position, the second cover body covers the first air outlet to prevent the airflow from directly passing through the second air outlet and the first air outlet and then flowing out of the heating device.

[0010] The design of the dial button allows the user to control the rotation of the second cover body by operating the dial button, and can control whether the heating device exhausts air outward through the first air outlet, thereby enriching the exhaust mode of the heating device. When using the heating device, the user can control the rotation of the second cover body by the dial button to open and close the first air outlet of the heating device, reducing the difficulty of controlling the opening and closing of the first air outlet of the heating device, and facilitating user use. At the same time, when the heating device is working, the heated air flow flows out through the first air outlet. The heat is concentrated in the middle area of ​​the first air outlet and the temperature is relatively high. Therefore, by setting the dial button on the periphery of the second air outlet, the user does not need to put his hand on the top of the first air outlet when manually operating the dial button. The user only needs to operate the dial button on the periphery of the second air outlet to close the first air outlet and the cavity. This reduces the direct contact between the user's hand and the high-temperature airflow at the first air outlet when the user operates the second cover to rotate, thereby avoiding scalding the user by the heat flow discharged from the first air outlet. At the same time, it also reduces the difficulty of adjusting the exhaust mode of the heating device, facilitates user operation, and can also improve the safety of the heating device and enhance the user experience of the heating device.

[0011] Furthermore, when the heating device is working, the user can operate the button arranged on the periphery of the second air outlet to complete the rotation of the second cover body, thereby preventing the user's hands from directly contacting the high-temperature heat flow and reducing the risk of burns to the user's hands.

[0012] Furthermore, when the heating device exhausts air through the first air outlet, the air flow heated by the heating component will be discharged through the first air outlet, and the user can control the rotation of the second cover body by means of a dial button arranged on the periphery of the second air outlet, thereby closing the first air outlet while preventing the heat flow from the first air outlet from directly contacting the user's hands, thereby reducing the risk of burns to the user's hands due to direct contact with the heat flow.

[0013] Furthermore, since the hot air at the first air outlet will directly contact the first cover body and the second cover body, the temperature at the first cover body and the second cover body is relatively high. The user can control the second cover body by controlling the button on the side of the second cover body, thereby avoiding the user from touching the high temperature area during operation and reducing the risk of the user being burned by high temperature.

[0014] Furthermore, the first cover body and the second cover body are arranged to be rotatably connected, which can reduce the difficulty of opening and closing the first air outlet, and can also simplify the connection structure of the first cover body and the second cover body, thereby reducing the installation cost.

[0015] In addition, the heating device in the above technical solution provided by the utility model may also have the following additional technical features:

[0017] In this technical solution, the heating device also includes a fixing seat and a connecting piece. The fixing seat is in contact with the first cover body. Since the fixing seat is located on the side of the first cover body away from the cavity, when the fixing seat is assembled on the first cover body, the fixing seat can limit the movement of the first cover body toward the side away from the cavity, thereby improving the stability of the first cover body after installation. When the heating device is working, the airflow in the cavity will be discharged outward through the first air outlet, and the flowing airflow will impact the first cover body. By setting the fixing seat, the movement of the first cover body toward the side away from the cavity can be limited, thereby preventing the first cover body from being displaced by the airflow, thereby improving the stability of the overall structure of the heating device.

[0018] The connecting member includes a fixing portion and a first connecting portion. The fixing portion is located on a side of the second cover body close to the cavity. The first connecting portion is connected to the fixing portion and is connected to the fixing seat. Since the fixing seat is arranged on a side of the first cover body away from the cavity, and the fixing portion is located on a side of the second cover body close to the cavity, the connection between the first cover body and the second cover body can be made more stable by setting the fixing seat and connecting the first connecting portion to the fixing portion, and the first cover body and the second cover body are limited, thereby reducing the shaking of the first cover body and the second cover body in the heating device and improving the structural stability of the heating device. At the same time, since the fixing seat and the fixing portion are connected by the first connecting portion to complete the fixing of the first cover body and the second cover body, the installation process of the first cover body and the second cover body can be simplified and the installation cost can be reduced.

[0019] Furthermore, due to the interconnection structure of the fixing part, the first connecting part and the fixing seat, the assembly efficiency of the first cover body and the second cover body can be improved. When the user performs maintenance on the heating device, the connection structure of the first connecting part to the fixing part and the fixing seat is also easy to disassemble, which is convenient for the maintenance of the heating device.

[0020] In some technical solutions of the utility model, optionally, the heating device also includes a protective cover, which is provided on the first cover body and arranged along the outer peripheral edge of the first cover body.

[0021] In this technical solution, the heating device also includes a protective cover, which is arranged on the first cover body and arranged along the outer peripheral edge of the first cover body. When the heating device is working, the heated airflow will flow out through the first air outlet on the first cover body, which will cause the edge temperature of the first cover body to be higher. Therefore, by arranging a protective cover on the outer peripheral edge of the first cover body, the safety of the heating device can be further improved, and the risk of scalding the user by the edge of the first cover body can be reduced. When the heating device is working, the first air outlet will receive heated airflow. By arranging the protective cover arranged along the outer peripheral edge of the first cover body, when the user controls the first air outlet to be turned on and off, the contact between the user's hand and the high-temperature airflow can be reduced, thereby avoiding the heat flow at the first air outlet from scalding the user, reducing the difficulty of adjusting the exhaust mode of the heating device, improving the safety of the heating device, and enhancing the user experience of the heating device.

[0022] In some technical solutions of the utility model, optionally, the heating device also includes a mounting seat, the mounting seat is connected to the shell; the protective cover is connected to the mounting seat; and the first cover body is arranged between the mounting seat and the protective cover.

[0023] In this technical solution, the heating device also includes a mounting seat, which is connected to the shell, which can ensure the stability of the overall structure of the heating device, improve the structural strength of the heating device, and facilitate the fixed installation of the protective cover in the heating device, thereby reducing the difficulty of assembling the heating device, and reducing the risk of damage to the heating device due to external forces, thereby extending the service life of the device. The protective cover is connected to the mounting seat, which facilitates the installation of the protective cover, improves the assembly efficiency of the heating device, and improves the safety of the heating device. The first cover body is arranged between the mounting seat and the protective cover, which can improve the structural stability of the first cover body and facilitate the disassembly of the first cover body.

[0024] In some technical schemes of the utility model, optionally, the mounting seat includes a first positioning portion and a second positioning portion; the dial button is arranged between the first positioning portion and the second positioning portion; wherein, when the second cover body is rotated to a first position relative to the first cover body, the dial button abuts against the first positioning portion; when the second cover body is rotated to a second position relative to the first cover body, the dial button abuts against the second positioning portion.

[0025] In this technical solution, the mounting seat includes a first positioning portion and a second positioning portion; the dial button is arranged between the first positioning portion and the second positioning portion, and the first positioning portion and the second positioning portion can limit the dial button to avoid large fluctuations in the position of the dial button, which is convenient for user operation. Among them, when the second cover body rotates to the first position relative to the first cover body, the dial button abuts against the first positioning portion, and at this time, the first air outlet is connected to the cavity through the second air outlet, so that the airflow in the cavity can be discharged from the heating device through the first air outlet, thereby improving the exhaust efficiency of the heating device. When the second cover body rotates to the second position relative to the first cover body, the dial button abuts against the second positioning portion, the first air outlet is disconnected from the second air outlet, and the first air outlet is disconnected from the cavity, blocking the airflow in the cavity from flowing out of the heating device through the first air outlet, thereby realizing the closure of the exhaust airflow outside the heating device, and realizing that the user can manually operate the dial button to complete the adjustment of whether the heating device exhausts the air outside through the first air outlet, thereby improving the flexibility of the heating device. By providing the first positioning portion and the second positioning portion, the toggle range of the dial button can be limited, thereby improving the accuracy of the user's control of the second cover body by toggling the dial button and reducing the difficulty of operation.

[0026] In some technical solutions of the utility model, optionally, the button is connected to the edge of the second cover body and extends in a direction away from the second cover body; the side wall of the mounting seat is provided with a first notch, the button is inserted into the first notch, and the two side walls of the first notch on the circumference of the second cover body are respectively the first positioning portion and the second positioning portion.

[0027] In this technical solution, the dial button is connected to the edge of the second cover body and extends away from the second cover body, which is convenient for user operation. At the same time, when the user manually operates the dial button, the user does not need to put his hand above the first air outlet. He only needs to operate the dial button on the side of the second cover body to complete the disconnection of the first air outlet and the cavity, reducing the contact between the user's hand and the high-temperature airflow when the user operates the second cover body to rotate, thereby avoiding the heat flow at the first air outlet from scalding the user, reducing the difficulty of adjusting the exhaust mode of the heating device, improving the safety of the heating device, and enhancing the experience of the heating device. The side wall of the mounting seat is provided with a first notch, and the dial button is inserted into the first notch. The two side walls of the first notch on the circumference of the second cover body are respectively the first positioning part and the second positioning part. By setting the two side walls of the mounting seat as the first positioning part and the second positioning part respectively, the structural strength of the first positioning part and the second positioning part can be improved, and the durability of the first positioning part and the second positioning part can be improved. At the same time, when the user operates the dial button, the first positioning part and the second positioning part formed by the side wall can reduce the shaking of the positioning structure and improve the stability of the dial button during operation.

[0028] Since the two side walls of the second cover body are respectively provided as the first positioning portion and the second positioning portion, no additional positioning structure is required, thereby reducing the cost of the heating device.

[0029] In some technical solutions of the present utility model, optionally, a third positioning portion is provided on the circumference of the first cover body; and a fourth positioning portion is provided on the mounting seat, and the fourth positioning portion is connected to the third positioning portion.

[0030] In this technical solution, a third positioning portion is provided on the circumference of the first cover body; a fourth positioning portion is provided on the mounting seat, and the fourth positioning portion is connected to the third positioning portion. The mounting seat and the first cover body can be fixed to each other through the fixed connection between the fourth positioning portion and the third positioning portion. When the user operates the dial button, the fourth positioning portion and the third positioning portion can prevent the first cover body from rotating, and the first air outlet can be disconnected or connected with the second air outlet through the fixedly installed first cover body and the second cover body that can rotate relative to the first cover body. Then, the user can manually operate the dial button to control whether the heating device exhausts gas through the first air outlet, thereby improving the flexibility of the heating device.

[0032] In this technical solution, the shell is a metal shell; and / or the first cover is a metal cover; and / or the second cover is a metal cover; and / or the dial button is a plastic dial button. The first cover and the second cover made of metal can have good thermal conductivity and heat resistance, which can prevent the first cover and the second cover from being damaged when in contact with high-temperature gas, and also facilitate the heat dissipation of the heating device, while improving the durability of the first cover and the second cover, and making them less prone to damage. Setting the shell to a metal material can improve the rigidity of the shell and the structural strength of the heating device. At the same time, by setting the material of the dial button to a plastic material, the cost can be reduced, while preventing the dial button from overheating, affecting the user's operation, and reducing the probability of the user's hands being scalded by the high temperature of the heating device.

[0033] The second aspect of the utility model provides a heating device, including a shell, a first cover body, a heating component, a second cover body, a fixing seat and a connecting piece, the shell having an air inlet and a cavity, the air inlet is connected to the cavity, the first cover body is located on a side of the cavity away from the air inlet, the first cover body is provided with a first air outlet, the heating component is arranged in the cavity, the second cover body can rotate relative to the first cover body, the second cover body is provided with a second air outlet, the fixing seat is located on a side of the first cover body away from the cavity, the connecting piece includes a fixing part and a first connecting part, the fixing part is located on a side of the second cover body close to the cavity, the first connecting part is connected to the fixing part and to the fixing seat, the fixing part and the fixing seat clamp the first cover body and the second cover body, and can limit the first cover body and the second cover body, wherein when the second cover body rotates to a first position relative to the first cover body, the first air outlet is connected to the second air outlet; when the second cover body rotates to a second position relative to the first cover body, the first air outlet is disconnected from the second air outlet.

[0034] A heating device provided in the present application includes a shell, a first cover, a heating component, a second cover, a fixing seat and a connector. The shell has an air inlet and a cavity. The air inlet is connected to the cavity, so that gas can enter the cavity through the air inlet, thereby improving the air intake efficiency of the heating device. The first cover is located on the side of the cavity away from the air inlet. The first cover is provided with a first air outlet. The cavity of the heating device can be protected by the first cover to prevent pollutants from entering the heating device. At the same time, the air outlet efficiency of the heating device can be improved by providing the first air outlet. The heating component is provided in the cavity. When the heating device is working, the external gas of the heating device can enter the cavity through the air inlet. The heating device can heat the gas through the heating component. The heated gas can flow out of the heating device through the first air outlet on the first cover, thereby increasing the ambient temperature, providing warm airflow to the user, and improving the experience of the heating device. The second cover body can rotate relative to the first cover body, and the second cover body is provided with a second air outlet. The fixing seat is located at a side of the first cover body away from the cavity. The connecting member includes a fixing portion and a first connecting portion. The fixing portion is located at a side of the second cover body close to the cavity. The first connecting portion is connected to the fixing portion and connected to the fixing seat. The fixing portion and the fixing seat clamp the first cover body and the second cover body, and the first cover body and the second cover body can be limited. When the second cover body rotates to the first position relative to the first cover body, the first air outlet is connected to the second air outlet, so that the airflow in the cavity can be discharged from the heating device through the first air outlet, thereby improving the exhaust efficiency of the heating device; when the second cover body rotates to the second position relative to the first cover body, the first air outlet is disconnected from the second air outlet. It is prevented that the airflow in the cavity flows out of the heating device directly through the first air outlet, thereby realizing the closing of the exhaust airflow outside the heating device, and realizing that the user can adjust whether the heating device exhausts the air outside through the first air outlet by manually operating the second cover body, thereby improving the flexibility of the heating device. Since the fixing seat is located on the side of the first cover body away from the cavity, when the fixing seat is assembled on the first cover body, the fixing seat can limit the movement of the first cover body to the side away from the cavity, which can improve the stability of the first cover body after installation. When the heating device is working, the airflow in the cavity will be discharged outward through the first air outlet, and the flowing airflow will impact the first cover body. By setting the fixing seat, the movement of the first cover body away from the cavity can be limited, so as to avoid the displacement of the first cover body due to the influence of the airflow, thereby improving the stability of the overall structure of the heating device. The connecting member includes a fixing portion and a first connecting portion, the fixing portion is located on the side of the second cover body close to the cavity, the first connecting portion is connected to the fixing portion, and is connected to the fixing seat.

[0035] The fixing base and the connecting piece are provided to limit the position of the first cover body and the second cover body, and the tightness between the first cover body and the second cover body can be adjusted by adjusting the tightness of the fixing base and the connecting piece, thereby improving the flexibility of relative rotation of the first cover body and the second cover body. Therefore, when the contact between the first cover body and the second cover body is tight, the tightness of the first cover body and the second cover body can be adjusted by adjusting the fixing base and the connecting piece, so that there is appropriate friction between the first cover body and the second cover body, thereby avoiding rotation difficulties caused by thermal deformation of the first cover body and the second cover body, reducing the amount of force required for the user to rotate the second cover body, and facilitating user operation.

[0036] By setting the second cover body to be rotatable relative to the first cover body, and the second cover body being provided with a second air outlet, the user can manually rotate the second cover body to control whether the heating device exhausts gas through the first air outlet, thereby enriching the exhaust mode of the heating device and improving the flexibility of the heating device.

When the heating device is working, the airflow in the cavity will be discharged outward through the first air outlet, and the flowing airflow will impact the first cover body. By setting the first body of the fixing seat in contact with the first cover body, the first cover body can be limited from moving toward the side away from the cavity, and the first cover body can be prevented from shifting due to the airflow.

DETAILED DESCRIPTION

[0071] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. 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.

[0072] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0073] Refer to the following Figures 1 to 11 A heating device according to some embodiments of the present invention is described.

[0074] like Figure 1 and Figure 2 As shown, in an embodiment of the utility model, a heating device 100 is provided, including a shell 110, a first cover 120, a heating component 130, a second cover 140 and a dial button 150, the shell 110 has an air inlet 112 and a cavity 114, the air inlet 112 is connected to the cavity 114, the first cover 120 is located on a side of the cavity 114 away from the air inlet 112, the first cover 120 is provided with a first air outlet 122, the heating component 130 is arranged in the cavity 114, The second cover body 140 can rotate relative to the first cover body 120, and the second cover body 140 is provided with a second air outlet 142. The button 150 is connected to the second cover body 140 and is located at the periphery of the second air outlet 142; wherein, when the second cover body 140 rotates to a first position relative to the first cover body 120, the first air outlet 122 is connected with the second air outlet 142; when the second cover body 140 rotates to a second position relative to the first cover body 120, the first air outlet 122 is disconnected from the second air outlet 142.

[0075] The present application provides a heating device 100, including a housing 110, a first cover 120, a heating assembly 130, a second cover 140 and a dial button 150. The housing 110 has an air inlet 112 and a cavity 114. The air inlet 112 is connected to the cavity 114, so that gas can enter the cavity 114 through the air inlet 112, thereby improving the air intake efficiency of the heating device 100. The first cover 120 is located on a side of the cavity 114 away from the air inlet 112. The first cover 120 is provided with a first air outlet 122. The first cover 120 can protect the cavity 114 of the heating device 100 to prevent pollutants from entering the heating device 100. At the same time, the air outlet efficiency of the heating device 100 can be improved by providing the first air outlet 122. By setting the heating component 130 in the cavity 114, when the heating device 100 is working, the external gas of the heating device 100 can enter the cavity 114 through the air inlet 112, and the heating device 100 can heat the gas through the heating component 130. The heated gas can flow out of the heating device 100 through the first air outlet 122 on the first cover body 120, which can increase the ambient temperature, provide warm airflow for users, and enhance the experience of the heating device 100.

[0076] The second cover 140 can rotate relative to the first cover 120, and the second cover 140 is provided with a second air outlet 142. The dial button 150 is connected to the second cover 140 and is located at the periphery of the second air outlet 142. When the second cover 140 rotates relative to the first cover 120 to the first position, the first air outlet 122 is connected to the second air outlet 142, so that the airflow in the cavity 114 can be discharged from the heating device 100 through the first air outlet 122, thereby improving the exhaust efficiency of the heating device 100. Air efficiency: when the second cover body 140 rotates to the second position relative to the first cover body 120, the first air outlet 122 is disconnected from the second air outlet 142, preventing the airflow in the cavity 114 from directly flowing out of the heating device 100 through the first air outlet 122, thereby achieving the closure of the direct exhaust airflow of the heating device 100, and enabling the user to control whether the heating device 100 exhausts gas through the first air outlet 122 by manually operating the button 150, thereby improving the flexibility of the heating device 100. Furthermore, when the second cover body 140 is rotated to the second position relative to the first cover body 120, the first air outlet 122 and the second air outlet 142 can be arranged alternately, and the first cover body 120 can cover the second air outlet 142, and the second cover body 140 can cover the side of the first air outlet 122 close to the cavity 114, so as to avoid the airflow directly passing through the second air outlet 142 and the first air outlet 122 and then flowing out of the heating device 100, and part of the airflow can be made to flow out of the heating device 100 through the gap between the first cover body 120 and the second cover body 140, thereby slowing down the airflow velocity, facilitating user use, and enriching the functionality of the heating device 100.

[0077] The user can operate the button 150 to rotate the second cover body 140 relative to the first cover body 120, and by setting the first air outlet 122 to be connected with the second air outlet 142 when the second cover body 140 is rotated to the first position relative to the first cover body 120, and the first air outlet 122 to be disconnected from the second air outlet 142 when the second cover body 140 is rotated to the second position relative to the first cover body 120, the user can control whether the heating device 100 exhausts gas through the first air outlet 122 by manually operating the button 150, thereby enriching the air outlet mode of the heating device 100 and improving the flexibility of the heating device 100. Furthermore, the user can control the area of ​​the first air outlet 122 covered by the second cover body 140 by rotating the second cover body 140, thereby controlling the exhaust area of ​​the first air outlet 122. When the second cover body 140 is rotated to the second position, the second cover body 140 covers the first air outlet 122 to prevent the airflow from directly passing through the second air outlet 142 and the first air outlet 122 and then flowing out of the heating device 100.

[0078] The design of the dial button 150 can facilitate the user to control the rotation of the second cover body 140 by operating the dial button 150, and can realize the control of whether the heating device 100 exhausts air outward through the first air outlet 122, thereby enriching the exhaust mode of the heating device 100. When using the heating device 100, the user can control the rotation of the second cover body 140 by the dial button 150 to complete the opening and closing of the first air outlet 122 of the heating device 100, reducing the difficulty of controlling the opening and closing of the first air outlet 122 of the heating device 100, and facilitating the use of the user. At the same time, when the heating device 100 is working, the heated air flow flows out through the first air outlet 122. The heat is concentrated in the middle area of ​​the first air outlet 122 and the temperature is relatively high. Therefore, by setting the dial button 150 on the periphery of the second air outlet 142, the user does not need to put his hand above the first air outlet 122 when manually operating the dial button 150. The user only needs to operate the dial button 150 on the periphery of the second air outlet 142 to close the first air outlet 122 and the cavity 114, thereby reducing the direct contact between the user and the high-temperature airflow when the user operates the second cover body 140 to rotate, thereby avoiding the heat flow at the first air outlet 122 from scalding the user. At the same time, it also reduces the difficulty of adjusting the exhaust mode of the heating device 100, improves the safety of the heating device 100, and can enhance the user experience of the heating device 100.

[0079] Furthermore, when the second cover body 140 is rotated to the second position relative to the first cover body 120, the first air outlet 122 is disconnected from the second air outlet 142, that is, the airflow cannot directly flow out through the first air outlet 122 after passing through the second air outlet 142. At this time, the first cover body 120 covers the second air outlet 142, so that the first air outlet 122 is disconnected from the second air outlet 142, blocking the hot air flow from directly flowing out of the heating device 100 through the first air outlet 122.

[0080] Specifically, the dial button 150 may be disposed at the periphery of the second air outlet 142 , or may be disposed at the side of the second cover body 140 .

[0081] Specifically, compared with setting a handle in the middle of the heating device 100, setting the dial button 150 on the periphery of the second air outlet 142, or on the side of the second cover body 140 can reduce the user's direct contact with the high-temperature airflow when rotating the second cover body 140, and also facilitate manual operation by the user, reducing the difficulty of rotation.

[0082] Furthermore, when the heating device 100 exhausts air through the first air outlet 122, the air flow heated by the heating component 130 will be discharged through the first air outlet 122, and the user can control the rotation of the second cover body 140 by means of the dial button 150 arranged on the side of the second cover body 140, thereby closing the first air outlet 122 while preventing the heat flow from the first air outlet 122 from directly contacting the user's hands, thereby reducing the risk of burns to the user's hands due to direct contact with the heat flow.

[0083] Furthermore, since the hot air at the first air outlet 122 will directly contact the first cover body 120 and the second cover body 140, the temperature at the first cover body 120 and the second cover body 140 is relatively high. The user can control the second cover body 140 by controlling the button 150 on the side of the second cover body 140, thereby preventing the user from touching the high temperature area during operation and reducing the risk of the user being burned by high temperature.

[0084] Furthermore, the first cover body 120 and the second cover body 140 are arranged to be rotatably connected, which can reduce the difficulty of opening and closing the first air outlet 122, and can also simplify the connection structure of the first cover body 120 and the second cover body 140, thereby reducing installation costs.

[0085] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0086] The heating device 100 also includes a fixing seat 160 and a connecting member 170. The fixing seat 160 contacts the first cover body 120 and is located on the side of the first cover body 120 away from the cavity 114. The connecting member 170 includes a fixing portion 172 and a first connecting portion 174. The fixing portion 172 is located on the side of the second cover body 140 close to the cavity 114. The first connecting portion 174 is connected to the fixing portion 172 and is also connected to the fixing seat 160.

[0087] In this embodiment, the heating device 100 also includes a fixing seat 160 and a connecting member 170. The fixing seat 160 is in contact with the first cover body 120. Since the fixing seat 160 is located on the side of the first cover body 120 away from the cavity 114, when the fixing seat 160 is assembled on the first cover body 120, the fixing seat 160 can limit the movement of the first cover body 120 toward the side away from the cavity 114, thereby improving the stability of the first cover body 120 after installation. When the heating device 100 is working, the airflow in the cavity 114 will be discharged outward through the first air outlet 122, and the flowing airflow will impact the first cover body 120. By setting the fixing seat 160, the first cover body 120 can be limited from moving toward the side away from the cavity 114, thereby preventing the first cover body 120 from shifting due to the airflow, thereby improving the stability of the overall structure of the heating device 100.

[0088] The connecting member 170 includes a fixing portion 172 and a first connecting portion 174. The fixing portion 172 is located on a side of the second cover body 140 close to the cavity 114. The first connecting portion 174 is connected to the fixing portion 172 and to the fixing seat 160. Since the fixing seat 160 is arranged on a side of the first cover body 120 away from the cavity 114, and the fixing portion 172 is located on a side of the second cover body 140 close to the cavity 114, the connection between the first cover body 120 and the second cover body 140 can be made more stable by setting the first connecting portion 174 to be connected to the fixing portion 172, the first cover body 120 and the second cover body 140 are limited, the shaking of the first cover body 120 and the second cover body 140 in the heating device 100 is reduced, and the structural stability of the heating device 100 is improved. At the same time, since the fixing seat 160 and the fixing portion 172 are connected by the first connecting portion 174, the first cover body 120 and the second cover body 140 are connected, the installation process of the first cover body 120 and the second cover body 140 can be simplified and the installation cost can be reduced.

[0089] Furthermore, by providing the interconnected structure of the fixing portion 172, the first connecting portion 174 and the fixing seat 160, the assembly efficiency of the first cover 120 and the second cover 140 can be improved. When the user performs maintenance on the heating device 100, the connection structure of the first connecting portion 174 to the fixing portion 172 and the fixing seat 160 is also easy to disassemble, which is convenient for the maintenance of the heating device 100.

[0090] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0091] The heating device 100 further includes a protection cover 180 , which is disposed on the first cover body 120 and along the outer peripheral edge of the first cover body 120 .

[0092] In this embodiment, the heating device 100 also includes a protective cover 180, which is covered on the first cover body 120 and arranged along the outer peripheral edge of the first cover body 120. When the heating device 100 is working, the heated air flow will flow out through the first air outlet 122 on the first cover body 120, which will cause the edge temperature of the first cover body 120 to be higher. Therefore, by arranging the protective cover 180 on the outer peripheral edge of the first cover body 120, the safety of the heating device 100 can be further improved and the risk of scalding the user by the edge of the first cover body 120 can be reduced. When the heating device 100 is working, the first air outlet 122 will have heated air flow. By providing a protective cover 180 arranged along the outer peripheral edge of the first cover body 120, the contact between the first air outlet 122 and the high-temperature air flow when the user operates the first air outlet 122 to be turned on and off can be reduced, thereby avoiding the heat flow at the first air outlet 122 from scalding the user, reducing the difficulty of adjusting the exhaust mode of the heating device 100, improving the safety of the heating device 100, and enhancing the user experience of the heating device 100.

[0093] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0094] The heating device 100 further includes a mounting seat 190 , which is connected to the housing 110 ; a protective cover 180 is connected to the mounting seat 190 ; and a first cover body 120 is disposed between the mounting seat 190 and the protective cover 180 .

[0095] In this embodiment, the heating device 100 also includes a mounting seat 190, which is connected to the housing 110, which can ensure the stability of the overall structure of the heating device 100, improve the structural strength of the heating device 100, and facilitate the fixed installation of the protective cover 180 in the heating device 100, thereby reducing the difficulty of assembling the heating device 100, and reducing the risk of damage to the heating device 100 due to external forces, thereby extending the service life of the device. The protective cover 180 is connected to the mounting seat 190, which is convenient for the installation of the protective cover 180, and improves the safety of the heating device 100 while improving the assembly efficiency of the heating device 100. The first cover body 120 is arranged between the mounting seat 190 and the protective cover 180, which can improve the structural stability of the first cover body 120 and also facilitate the disassembly of the first cover body 120.

[0096] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0097] The mounting base 190 includes a first positioning portion 192 and a second positioning portion 194; the dial button 150 is arranged between the first positioning portion 192 and the second positioning portion 194; wherein, when the second cover body 140 rotates to the first position relative to the first cover body 120, the dial button 150 abuts against the first positioning portion 192; when the second cover body 140 rotates to the second position relative to the first cover body 120, the dial button 150 abuts against the second positioning portion 194.

[0098] In this embodiment, the mounting base 190 includes a first positioning portion 192 and a second positioning portion 194; the dial button 150 is disposed between the first positioning portion 192 and the second positioning portion 194, and the first positioning portion 192 and the second positioning portion 194 can limit the dial button 150 to prevent the position of the dial button 150 from fluctuating greatly, which is convenient for user operation. When the second cover 140 rotates to the first position relative to the first cover 120, the dial button 150 abuts against the first positioning portion 192. At this time, the first air outlet 122 is connected to the cavity 114 through the second air outlet 142, so that the airflow in the cavity 114 can be discharged from the heating device 100 through the first air outlet 122, thereby improving the exhaust efficiency of the heating device 100. When the second cover 140 rotates to the second position relative to the first cover 120, the dial button 150 abuts against the second positioning portion 194, the first air outlet 122 is disconnected from the second air outlet 142, and the first air outlet 122 is disconnected from the cavity 114, blocking the airflow in the cavity 114 from flowing out of the heating device 100 through the first air outlet 122, thereby closing the airflow of the heating device 100, and enabling the user to manually operate the dial button 150 to adjust whether the heating device 100 exhausts air through the first air outlet 122, thereby improving the flexibility of the heating device 100. By providing the first positioning portion 192 and the second positioning portion 194, the dial range of the dial button 150 can be limited, the accuracy of controlling the second cover 140 by the dial button 150 is improved, and the difficulty of operation is reduced.

[0099] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0100] The button 150 is connected to the edge of the second cover body 140 and extends in a direction away from the second cover body 140; the side wall of the mounting seat 190 is provided with a first notch 196, and the button 150 is inserted into the first notch 196. The two side walls of the first notch 196 on the circumference of the second cover body 140 are respectively a first positioning portion 192 and a second positioning portion 194.

[0101] In this embodiment, the button 150 is connected to the edge of the second cover body 140 and extends away from the second cover body 140, which is convenient for user operation. At the same time, when the user manually operates the button 150, there is no need to place the hand above the first air outlet 122. The user only needs to operate the button 150 on the side of the second cover body 140 to disconnect the conduction between the first air outlet 122 and the cavity 114, thereby reducing the contact between the user and the high-temperature airflow when the user operates the second cover body 140 to rotate, thereby avoiding the heat flow at the first air outlet 122 from scalding the user, reducing the difficulty of adjusting the exhaust mode of the heating device 100, improving the safety of the heating device 100, and enhancing the user experience of the heating device 100. A first notch 196 is provided on the side wall of the mounting base 190, and the dial button 150 is inserted into the first notch 196. The two side walls of the first notch 196 in the circumferential direction of the second cover body 140 are respectively the first positioning portion 192 and the second positioning portion 194. By respectively setting the two side walls of the second cover body 140 as the first positioning portion 192 and the second positioning portion 194, the structural strength of the first positioning portion 192 and the second positioning portion 194 can be improved, and the durability of the first positioning portion 192 and the second positioning portion 194 can be improved. At the same time, when the user operates the dial button 150, the first positioning portion 192 and the second positioning portion 194 formed on the side wall can reduce the shaking of the positioning structure and improve the stability of the dial button 150 during operation.

[0102] Specifically, the circumferential direction of the first cover body 120 and the second cover body 140 is K.

[0103] Since the two side walls of the second cover body 140 are respectively provided as the first positioning portion 192 and the second positioning portion 194 , no additional positioning structure is required, thereby reducing the cost of the heating device 100 .

[0104] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0105] A third positioning portion 124 is disposed on the circumference of the first cover 120 ; a fourth positioning portion 126 is disposed on the mounting seat 190 , and the fourth positioning portion 126 is connected to the third positioning portion 124 .

[0111] The present application provides a heating device 100, including a housing 110, a first cover 120, a heating assembly 130, a second cover 140, a fixing seat 160 and a connector 170. The housing 110 has an air inlet 112 and a cavity 114. The air inlet 112 is connected to the cavity 114, so that gas can enter the cavity 114 through the air inlet 112, thereby improving the air intake efficiency of the heating device 100. The first cover 120 is located on a side of the cavity 114 away from the air inlet 112. The first cover 120 is provided with a first air outlet 122. The first cover 120 can protect the cavity 114 of the heating device 100 to prevent pollutants from entering the heating device 100. At the same time, the air outlet efficiency of the heating device 100 can be improved by providing the first air outlet 122. The heating component 130 is arranged in the cavity 114. When the heating device 100 is working, the external gas of the heating device 100 can enter the cavity 114 through the air inlet 112. The heating device 100 can heat the gas through the heating component 130. The heated gas can flow out of the heating device 100 through the first air outlet 122 on the first cover body 120, which can increase the ambient temperature, provide warm airflow for users, and enhance the experience of the heating device 100. The second cover 140 can rotate relative to the first cover 120, and the second cover 140 is provided with a second air outlet 142. The fixing seat 160 is located on the side of the first cover 120 away from the cavity 114. The connecting member 170 includes a fixing portion 172 and a first connecting portion 174. The fixing portion 172 is located on the side of the second cover 140 close to the cavity 114. The first connecting portion 174 is connected to the fixing portion 172 and is connected to the fixing seat 160. The fixing portion 172 and the fixing seat 160 sandwich the first cover 120 and the second cover 120. The second cover 140 can limit the first cover 120 and the second cover 140, wherein when the second cover 140 rotates to the first position relative to the first cover 120, the first air outlet 122 is connected with the second air outlet 142, so that the airflow in the cavity 114 can be discharged from the heating device 100 through the first air outlet 122, thereby improving the exhaust efficiency of the heating device 100; when the second cover 140 rotates to the second position relative to the first cover 120, the first air outlet 122 is disconnected from the second air outlet 142. This prevents the airflow in the cavity 114 from directly flowing out of the heating device 100 through the first air outlet 122, thereby closing the exhaust airflow outside the heating device 100, and enabling the user to manually operate the second cover 140 to adjust whether the heating device 100 exhausts air outside through the first air outlet 122, thereby improving the flexibility of the heating device 100.Since the fixing seat 160 is located on the side of the first cover body 120 away from the cavity 114, when the fixing seat 160 is assembled on the first cover body 120, the fixing seat 160 can limit the first cover body 120 from moving toward the side away from the cavity 114, thereby improving the stability of the first cover body 120 after installation. When the heating device 100 is working, the airflow in the cavity 114 will be discharged outward through the first air outlet 122, and the flowing airflow will impact the first cover body 120. By setting the fixing seat 160, the first cover body 120 can be limited from moving toward the side away from the cavity 114, thereby preventing the first cover body 120 from shifting due to the airflow, thereby improving the stability of the overall structure of the heating device 100. The connecting member 170 includes a fixing portion 172 and a first connecting portion 174. The fixing portion 172 is located on a side of the second cover body 140 close to the cavity 114. The first connecting portion 174 is connected to the fixing portion 172 and to the fixing seat 160. Since the fixing seat 160 is arranged on a side of the first cover body 120 away from the cavity 114, and the fixing portion 172 is located on a side of the second cover body 140 close to the cavity 114, by arranging the first connecting portion 174 to be connected to the fixing portion 172 and clamping the first cover body 120 and the second cover body 140, the connection between the first cover body 120 and the second cover body 140 can be made more stable, the first cover body 120 and the second cover body 140 can be limited, the shaking of the first cover body 120 and the second cover body 140 in the heating device 100 can be reduced, and the structural stability of the heating device 100 can be improved. At the same time, since the fixing seat 160 and the fixing portion 172 are connected by the first connecting portion 174, the first cover body 120 and the second cover body 140 are connected, the installation process of the first cover body 120 and the second cover body 140 can be simplified and the installation cost can be reduced.

[0112] The user can manually rotate the second cover 140 to control whether the heating device 100 exhausts gas through the first air outlet 122, enrich the exhaust mode of the heating device 100, and improve the flexibility of the heating device 100. Furthermore, the user can control the area of ​​the first air outlet 122 covered by the second cover 140 by rotating the second cover 140, thereby controlling the exhaust area of ​​the first air outlet 122. When the second cover 140 rotates to the second position, the second cover 140 covers the first air outlet 122, preventing the airflow from directly passing through the second air outlet 142 and the first air outlet 122 and then flowing out of the heating device 100.

[0113] The fixing base 160 and the connecting piece 170 are provided to limit the first cover body 120 and the second cover body 140. At the same time, the tightness between the first cover body 120 and the second cover body 140 can be adjusted by adjusting the tightness of the fixing base 160 and the connecting piece 170, thereby improving the flexibility of relative rotation of the first cover body 120 and the second cover body 140. Therefore, when the contact between the first cover body 120 and the second cover body 140 is tight, the tightness of the first cover body 120 and the second cover body 140 can be adjusted by adjusting the fixing base 160 and the connecting piece 170, so that there is appropriate friction between the first cover body 120 and the second cover body 140 during rotation, thereby avoiding rotation difficulties caused by heat deformation of the first cover body 120 and the second cover body 140, reducing the force required for the user to rotate the second cover body 140, and facilitating user operation.

When the heating device 100 is working, the airflow in the cavity 114 will be discharged outward through the first air outlet 122, and the flowing airflow will impact the first cover 120. By setting the first body 162 of the fixing seat 160 to contact the first cover 120, the first cover 120 can be limited from moving away from the cavity 114. The cavity 114 moves sideways to prevent the first cover body 120 from being displaced by the airflow. The second connecting portion 163 is connected to the first body 162 and extends toward the cavity 114. The second connecting portion 163 is provided with a threaded hole 164; the first connecting portion 174 is a threaded connecting portion 176, and the threaded connecting portion 176 is arranged in the threaded hole 164, which can realize the quick connection between the first connecting portion 174 and the second connecting portion 163, simplify the assembly process between the fixing seat 160 and the first cover body 120, and reduce the installation difficulty while ensuring the structural strength of the fixing seat 160, thereby reducing the cost.

Since the fixing seat 160 is arranged on the side of the first cover body 120 away from the cavity 114, and the fixing sleeve 165 is located on the side of the second cover body 140 close to the cavity 114, the second connecting portion 163 is connected to the fixing sleeve 165 to make the connection between the first cover body 120 and the second cover body 140 more stable, and the first cover body 120 and the second cover body 140 are limited. The gasket 166 is located at the second end of the fixing sleeve 165 ; the fixing portion 172 abuts against the gasket 166 .
