[0036] Next, reference is made to Figures 1 - 4 describe the heater 100 according to an embodiment of the present utility model.

[0037] As Figure 3 shown, the heater 100 according to the present utility model includes: a housing 110, a duct space 111 is provided inside the housing 110, and an air inlet 112 and an air outlet 113 are provided in the duct space 111; a heating element 120, the heating element 120 is disposed in the duct space 111, and the housing 110 is configured to radiate the heat generated by the heating element 120 outward.

[0038] Specifically, the air inlet 112 and the air outlet 113 can be formed on the housing 110. Airflow can enter the duct space 111 from the air inlet 112. The heating element 120 can be used to heat the airflow. The heated airflow can be discharged from the air outlet 113 out of the duct space 111 to realize the convective heating function of the heater 100. At the same time, the heat generated by the heating element 120 can be transferred to the housing 110 and radiated to the external environment (for example: indoor environment) through the housing 110, thereby realizing the radiant heating of the heater 100. Thus, the heater 100 can simultaneously realize radiant heating and convective heating, effectively improving the heating effect of the heater 100 and enhancing the user experience.

[0039] Furthermore, the housing 110 can shield the heating element 120 to reduce the light emitted to the external environment when the heating element 120 is operating, preventing the large amount of light emitted by the heating element 120 to the external environment from affecting the user's sleep and further improving the user's experience.

[0040] In addition, after the heating element 120 heats the air flow, the air flow can transfer heat to the housing 110 when flowing in the air duct space 111, so as to further increase the temperature of the housing 110, thereby increasing the heat radiated by the housing 110 to the external environment, which is beneficial to ensuring the temperature uniformity of the upper and lower spaces of the external environment, preventing the large temperature difference between the upper and lower spaces of the external environment caused by the hot air flow quickly gathering at a high altitude after being discharged through the air outlet 113, ensuring the thermal comfort of the heater 100 and improving the user's experience.

[0041] Combined Figure 2 with Figure 3 , the heater 100 further includes a flow guiding component 130, which is arranged in the air duct space 111. The flow guiding component 130 is configured to define the flow path of the air flow, and the flow guiding component 130 makes the flow path have at least one turning part for the air flow to turn.

[0042] Specifically, the flow guiding component 130 is connected to the housing 110 and is located in the air duct space 111. The flow guiding component 130 is used to define the flow path of the air flow in the air duct space 111, and the flow guiding component 130 makes the flow path have a turning part for the air flow to turn, so as to extend the flow path of the air flow, increase the flow time of the air flow in the air duct space 111, delay the hot air flow from bringing heat to a high altitude, and can improve the effect of the hot air flow transferring heat to the housing 110 in the air duct space 111, increase the heat radiated by the housing 110 to the external environment, increase the proportion of radiant heating of the heater 100 and reduce the proportion of convective heating, so that more heat can stay at a low altitude position or first heat the low-altitude air flow and then rise to a high altitude position, ensure the temperature uniformity of the upper and lower spaces, improve the thermal comfort of the heater 100 and improve the user's experience.

[0043] Optionally, one flow guiding component 130 can be provided and configured as a straight plate structure. The straight plate structure can be arranged between the air inlet 112 and the air outlet 113, and the straight plate structure can be arranged opposite to the air inlet 112 and offset from the air outlet 113. When the air flow enters the air duct space 111 through the air inlet 112, the plate body (i.e., the above-mentioned straight plate structure) can prevent the air flow from directly flowing to the air outlet 113. The flow path has a turning part, and the air flow needs to bypass the plate body and flow to the air outlet 113, thereby realizing the change of the air flow path, extending the flow path of the air flow in the air duct space 111, and ensuring that the heated air flow can fully exchange heat with the housing 110.

[0044] Alternatively, the flow guide assembly 130 may include a plurality of straight plate structures which may be arranged at intervals between the air inlet 112 and the air outlet 113, such that the flow path of the air flow has a plurality of turning portions, and the flow path of the air flow can be further extended to ensure that the heated air flow can fully exchange heat with the housing 110.

[0045] Alternatively, the flow guide assembly 130 may include a bent plate structure which defines a flow path having a plurality of turning portions; or the flow guide assembly 130 may include a plurality of bent plate structures; or the flow guide assembly 130 may be a combination of a bent plate structure and a straight plate structure.

[0046] Of course, it can be understood that the above arrangements of the flow guide assembly 130 are only several embodiments of the present invention and should not be construed as a limitation to this application. The specific arrangement of the flow guide assembly 130 may be determined according to actual production requirements and actual heat exchange requirements, as long as it can ensure that the flow guide assembly 130 can achieve the effect of extending the flow path of the air flow, and no specific limitation is made herein.

[0047] In the related art, a radiant heater needs to form an open structure by opening holes in the outer shell to ensure the effect of the heating element radiating heat to the outside. Since the outer shell is an open structure, the heater cannot achieve air flow convection heating, and the light generated by the heating element will be emitted to the outside through the open outer shell, affecting the user's sleep; for a balanced heater, after heating the air flow, the hot air flow will directly rush to a high altitude quickly, resulting in a large temperature difference between the upper and lower spaces, thus resulting in poor thermal comfort.

[0048] The housing 110 of the present application can radiate the heat of the heating element 120 to the external environment to achieve the radiant heating function. By providing the flow guide assembly 130 to extend the flow path of the air flow in the air duct space 111, increasing the flow time of the air flow in the air duct space 111, delaying the air flow from bringing the heat to a high altitude, and improving the effect of the air flow transferring the heat to the housing 110 in the air duct space 111, increasing the heat radiated by the housing 110 to the external environment, increasing the proportion of radiant heating of the heater 100 and reducing the proportion of convection heating, so that more heat can be retained at a low altitude position or the low-altitude air flow can be heated first and then rise to a high altitude position to ensure the temperature uniformity of the upper and lower spaces. Moreover, the housing 110 can shield the heating element 120 to reduce the light emitted to the external environment when the heating element 120 works, preventing the user's sleep from being affected due to a large amount of light emitted by the heating element 120 to the external environment during operation; the housing 110 is provided with an air inlet 112 and an air outlet 113, and the air flow can be discharged through the air outlet 113 after being heated by the heating element 120 to achieve the convection heating of the heater 100.

[0049] According to the heater 100 of the present utility model, by constructing the housing 110 to radiate the heat generated by the heating element 120 outward, by providing a diversion assembly 130 to extend the flow path of the air flow in the air duct space 111, increasing the flow time of the air flow in the air duct space 111, delaying the air flow from carrying the heat to a high altitude, and improving the effect of the air flow transferring the heat to the housing 110, so as to further increase the temperature of the housing 110, thereby increasing the heat radiated by the housing 110 to the external environment, and providing an air inlet 112 and an air outlet 113 on the housing 110, so that the heater 100 can achieve convective heating and radiative heating, ensuring the temperature uniformity of the upper and lower spaces of the external environment, and the housing 110 can shield the heating element 120 to prevent the light emitted by the heating element 120 during operation from affecting the user's sleep and improving the user's experience.

[0050] Combined with Figure 2 and Figure 3 , in some embodiments of the present utility model, a water storage cavity 114 with an open top is provided in the air duct space 111, and the air outlet 113 is located above the water storage cavity 114.

[0051] It should be noted that "top" and "bottom" refer to both sides of the heater 100 in the height direction (i.e., the second direction), where "top" refers to the side of the heater 100 away from the ground in the height direction, and "bottom" refers to the side of the heater 100 close to the ground in the height direction.

[0052] Specifically, the water storage cavity 114 can be used to store water. The heat generated by the heating element 120 can heat and evaporate the water in the water storage cavity 114. An open mouth is formed on the side of the water storage cavity 114 facing the air outlet 113. The water vapor can escape from the water storage cavity 114 through the open mouth and can be discharged into the external environment through the air outlet 113 to humidify the external environment, thereby realizing the humidification function of the heater 100 and improving the functionality of the heater 100. In addition, water can also be added to the water storage cavity 114 through the air outlet 113.

[0053] Furthermore, the water in the water storage cavity 114 can be directly heated by the heat generated by the heating element 120. At the same time, the housing 110 can transfer heat to heat the water in the water storage cavity 114, and the hot air flow can also heat the water in the water storage cavity 114 to increase the evaporation amount of the water and ensure the humidification effect of the heater 100.

[0054] In the related art, heaters with a humidification function usually need to be provided with devices such as a water washing cotton, an additional heat source or an ultrasonic vibration sheet in the heater to increase the evaporation area of the water, resulting in a high production cost of the heater.

[0055] The heat radiated by the heating element 120, the hot air flow, and the housing 110 of the present application can simultaneously heat the water in the water storage cavity 114, effectively increasing the evaporation amount of the water, ensuring the humidifying effect of the heater 100, and without the need to provide components such as a water-washing cotton or an ultrasonic vibrating sheet, reducing the production cost of the heater 100 while realizing the humidifying function of the heater 100.

[0056] Optionally, the water storage cavity 114 can be directly used for storing water to further simplify the component arrangement of the heater 100 and reduce the production cost of the heater 100; or a water tank with an open top can be separately provided in the water storage cavity 114 for storing water, which is convenient for users to repair or replace the water tank. The specific structural arrangement can be determined according to actual production requirements and will not be specifically limited herein.

[0057] As Figure 3 shown, in some embodiments of the present invention, the air inlet 112 is located at the bottom of the air duct space 111, the air outlet 113 is located at the top of the air duct space 111, and the heating element 120 is disposed between the air inlet 112 and the air outlet 113, which is beneficial to ensuring the heating effect of the heating element 120 on the air flow. And the heated air flow expands due to heat. By providing the air outlet 113 at the top of the air duct space 111, it is beneficial to the discharge of the hot air flow, ensuring the discharge effect of the hot air flow, and is beneficial to ensuring the convective heating effect of the heater 100. Combining Figure 2 and Figure 3 , in some embodiments of the present invention, both the air inlet 112 and the air outlet 113 are provided on the housing 110, and the housing 110 is provided with grilles 170 at the positions of the air inlet 112 and the air outlet 113. The grilles 170 are used to prevent the heater 100 from being damaged due to dust or debris entering the interior of the heater 100, ensuring the service life of the heater 100.

[0058] Combining Figure 2 and Figure 3 , in some embodiments of the present invention, the flow guiding assembly 130 includes a first flow guiding rib 131 disposed above the heating element 120. The first flow guiding rib 131 includes a first portion 1311 and a second portion 1312 having an included angle. One end of the first portion 1311 is connected to the inner wall of the housing 110 and the other end is spaced from the inner wall of the housing 110. The lower end of the second portion 1312 is connected to the other end of the first portion 1311 and extends upward.

[0059] Specifically, the housing 110 has two inner walls facing each other in the first direction. The first portion 1311 can extend in the first direction, and one end of the first portion 1311 is connected to one of the two inner walls, and the other end of the first portion 1311 is spaced from the other of the two inner walls.

[0060] Further, the second part 1312 is connected to one end of the first part 1311 which is spaced from the inner wall, and the second part 1312 extends from the first part 1311 in the second direction towards the top wall of the housing 110, and the upper end of the second part 1312 is spaced from the top wall of the housing 110. Thus, the first flow guiding rib 131 can define a flow path of the air flow, and the flow path has a plurality of turning portions.

[0061] It should be noted that the "first direction" refers to the left-right direction, which can also be understood as the width direction of the heater 100, and the "second direction" refers to the up-down direction, which can also be understood as the height direction of the heater 100. For the specific direction illustration, reference can be made to Figure 3 as shown.

[0062] Specifically, when the air flow enters the air duct space 111 through the air inlet 112, the air flow flows in the second direction to the first part 1311. The first part 1311 restricts the air flow from continuing to flow in the second direction and causes the air flow to flow in the first direction. During this process, the air flow passes through the heating element 120 and is heated. Then, the hot air flow flows in the second direction to the position where the first part 1311 of the first flow guiding rib 131 is spaced from the inner wall of the housing 110. The inner wall of the housing 110 and the second part 1312 adjust the hot air flow to flow in the second direction, and the hot air flow can further flow to the air outlet 113 through the gap between the second part 1312 and the top wall of the housing 110.

[0063] Thus, by providing the first flow guiding rib 131 in the air duct space 111 to extend the flow path of the air flow in the air duct space, the effect of the hot air flow transferring heat to the housing 110 is improved, and the discharge of the hot air flow to the upper space of the external environment can be delayed.

[0064] Referring to Figure 3 , in some embodiments of the present utility model, a water storage cavity 114 is provided in the air duct space 111, and the first flow guiding rib 131 and the inner wall of the housing 110 cooperate to define the water storage cavity 114.

[0065] Specifically, the first part 1311 of the first flow guiding rib 131 extends in the first direction, and the second part 1312 is perpendicular to the first part 1311 and extends towards the top wall of the housing 110. That is, the first flow guiding rib 131 is configured in an L shape. The first flow guiding rib 131 and the inner wall of the housing 110 jointly define the water storage cavity 114. The water storage cavity 114 can be directly used for storing water, or when a water tank is provided in the air duct space 111, the first flow guiding rib 131 can be used to support the water tank, improving the functionality of the first flow guiding rib 131, and can simplify the component arrangement in the housing 110, reduce the production cost of the heater 100, and at the same time is beneficial to simplifying the assembly process of the heater 100.

[0066] During the flow of the air current, the air current is heated by the heating member 120 and flows along the first part 1311 of the first flow guiding rib 131. The air current can transfer heat to the first part 1311, and the first part 1311 further transfers the heat to the water in the water storage cavity 114, thereby realizing the heating of the water.

[0067] Combined with Figure 2 and Figure 3 , in some embodiments of the present invention, the flow guiding assembly 130 further includes a second flow guiding rib 132. The second flow guiding rib 132 is disposed on the top wall of the housing 110 and extends downward. The air outlet 113 is located on the side of the second flow guiding rib 132 away from the second part 1312.

[0068] Specifically, combined with Figures 2 - 4 , the second flow guiding rib 132 is disposed opposite to the water storage cavity 114 in the second direction, and the second flow guiding rib 132 extends from the top wall of the housing 110 towards the water storage cavity 114 in the second direction. The air outlet 113 is located on the side of the second flow guiding rib 132 away from the second part 1312 in the first direction. During the process of flowing towards the air outlet 113, the air current needs to bypass the second flow guiding rib 132, thereby further extending the flow path of the air current, delaying the heat of the hot air current from being brought to a high altitude, and improving the effect of the hot air current transferring heat to the housing 110 in the air duct space 111, increasing the heat radiated by the housing 110 to the external environment, so that more heat can remain at a low altitude position or first heat the low altitude air current and then rise to a high altitude position, ensuring the temperature uniformity of the upper and lower spaces.

[0069] As Figure 3 shown, in some embodiments of the present invention, the lower end of the second flow guiding rib 132 extends downward beyond the top surface of the second part 1312.

[0070] Specifically, in the second direction, the orthographic projection of the second flow guiding rib 132 falls within the orthographic projection of the first flow guiding rib 131, that is, the second flow guiding rib 132 extends from the top wall of the housing 110 towards the water storage cavity 114 in the second direction. In the orthographic projection direction of the first direction, the lower end of the second flow guiding rib 132 is located below the top end of the second part 1312. During the flow of the hot air current, the second flow guiding rib 132 can guide the hot air current to the first part 1311, and the hot air current further flows towards the air outlet 113 along the first part 1311, so as to further extend the flow path of the hot air current, improve the heating effect of the hot air current on the housing 110, and increase the temperature of the housing 110.

[0071] Furthermore, the lower end of the second flow guiding rib 132 is spaced from the first part 1311. The second flow guiding rib 132 can direct the air flow into the water holding cavity 114 to ensure the heating effect of the hot air on the water. The air outlet 113 is disposed opposite to the water holding cavity 114, and the water vapor can be discharged into the external environment through the air outlet 113, thereby realizing the humidifying function of the heater 100. At the same time, the air flow can carry the water vapor and be discharged into the external environment through the air outlet 113, improving the flow efficiency of the water vapor and thus enhancing the humidifying efficiency of the heater 100.

[0072] Combined with Figures 2 - 4 , in some embodiments of the present utility model, a drain hole 115 is provided on the side wall of the housing 110, and a plug 116 for opening or closing the drain hole 115 is provided at the drain hole 115.

[0073] Specifically, the drain hole 115 is used to drain the water in the water holding cavity 114. Among them, the drain hole 115 is disposed close to the first part 1311 in the second direction, that is, the drain hole 115 is close to the bottom wall of the water holding cavity 114, which is conducive to emptying the water in the water holding cavity 114 and ensuring the drainage effect.

[0074] Furthermore, when it is necessary to drain the water in the water holding cavity 114 (for example, when humidifying the external environment is not required), the plug 116 can be removed from the drain hole 115 to open the drain hole 115, and the water in the water holding cavity 114 can be drained through the drain hole 115; when it is not necessary to drain the water in the water holding cavity 114, the drain hole 115 can be closed by the plug 116 to prevent the water in the water holding cavity 114 from leaking out.

[0075] Combined with Figures 2 - 4 , in some embodiments of the present utility model, an overflow hole 117 is provided on the side wall of the housing 110, and the overflow hole 117 is higher than the drain hole 115 and lower than the lower end surface of the second flow guiding rib 132.

[0076] Specifically, in the second direction, the overflow hole 117 is higher than the drain hole 115 and lower than the top end of the second part 1312. When the water level in the water holding cavity 114 reaches the position of the overflow hole 117, the excess water can be discharged from the housing 110 through the overflow hole 117, preventing the water level from exceeding the top end of the second part 1312 and flowing out of the water holding cavity 114, thereby avoiding the contact between the water and the heating element 120 and preventing the heating element 120 from short-circuiting, ensuring the safety of the heater 100.

[0077] Further, in the second direction, the overflow hole 117 is lower than the lower end surface of the second guiding rib 132, that is, there is a gap between the water surface and the lower end surface of the second guiding rib 132, so as to facilitate the hot air flow through the water storage cavity 114, enabling the hot air to fully heat the water in the water storage cavity 114, improving the efficiency of water evaporation, and facilitating the hot air to flow towards the air outlet 113, preventing the hot air from being unable to escape due to the contact between the second guiding rib 132 and the water surface.

[0078] Combined with Figure 2 and Figure 3 , in some embodiments of the present invention, the guiding component 130 further includes a third guiding rib 133, the third guiding rib 133 is located on the side of the heating element 120 close to the air inlet 112, and is directly opposite to the air inlet 112.

[0079] Specifically, in the second direction, the orthographic projection area of the third guiding rib 133 can cover the air inlet 112, that is, the projection area of the third guiding rib 133 in the second direction is larger than the projection area of the air inlet 112 in the second direction. The third guiding rib 133 blocks the position where the heating element 120 is directly opposite to the air inlet 112, preventing the water in the water storage cavity 114 from splashing onto the heating element 120 through the air inlet 112 when discharging, so as to further avoid the contact between the heating element 120 and water, and improve the use safety of the heater 100.

[0080] Further, the third guiding rib 133 can guide the air flow to adjust the air flow to flow along the first direction, and the dimension of the third guiding rib 133 in the first direction is smaller than the dimension of the heating element 120 in the first direction, so that the air flow can flow through the heating element 120 after flowing through the third guiding rib 133, facilitating the heating element 120 to heat the air flow.

[0081] In some other embodiments of the present invention, the heating element 120 can be configured as a waterproof heating body. Since the heating element 120 has a waterproof function, the setting of the third guiding rib 133 can be cancelled, reducing the component setting in the housing 110, lowering the production cost of the heater 100, and being beneficial to realizing the lightweight design of the heater 100.

[0082] Combined with Figure 2 and Figure 3 , in some embodiments of the present invention, the heater 100 further includes an electric control component 140, the electric control component 140 is arranged in the air duct space 111, and is arranged in a dislocation manner with the air inlet 112.

[0083] Specifically, the electric control component 140 is used to control the operation of the heating element 120. The electric control component 140 is arranged in the air duct space 111 to improve the space utilization rate of the air duct space 111, and is beneficial to reducing the volume of the heater 100, thereby reducing the occupied space of the heater 100.

[0084] Further, the electronic control component 140 and the air inlet 112 are arranged out of alignment in the first direction to prevent the electronic control component 140 from blocking the air inlet 112, improve the air intake efficiency, and help prevent the water discharged from the water storage cavity 114 from splashing onto the electronic control component 140 through the air inlet 112, prevent the electronic control component 140 from short-circuiting, and improve the use safety of the heater 100.

[0085] Combined Figure 2 with Figure 3 , in some embodiments of the present utility model, a partition rib 150 is further provided in the air duct space 111. The partition rib 150 and the housing 110 jointly define an assembly space 151. The electronic control component 140 is arranged in the assembly space 151, and at least a part of the partition rib 150 is located on the side of the electronic control component 140 facing the air inlet 112.

[0086] Specifically, the partition rib 150 is arranged in the air duct space 111 and is arranged out of alignment with the air inlet 112. The partition rib 150 and the inner wall of the housing 110 jointly define an assembly space 151. The electronic control component 140 is arranged in the assembly space 151. The partition rib 150 can separate the electronic control component 140 from the air inlet 112 to protect the electronic control component 140, and further prevent the water discharged from the water storage cavity 114 from splashing onto the electronic control component 140 through the air inlet 112.

[0087] In addition, the partition rib 150 can also play a heat insulation role to reduce the problem that the temperature of the electronic control component 140 is too high to work due to the heat transfer of the heating element 120 and the hot air flow to the electronic control component 140, and at the same time can reduce potential safety hazards.

[0088] Optionally, the partition rib 150 can be entirely located on the side of the electronic control component 140 facing the air inlet 112, or the partition rib 150 can be arranged to surround the electronic control component 140 in the circumferential direction of the electronic control component 140, that is, a part of the partition rib 150 is located on the side of the electronic control component 140 facing the air inlet 112. The specific structure of the partition rib 150 can be determined according to actual production requirements and is not specifically limited herein as long as it is ensured that the partition rib 150 can play a role in protecting the electronic control component 140.

[0089] Combined Figures 1 - 3, in some embodiments of the present utility model, the housing 110 includes a first housing 1101, a second housing 1102 and a bottom cover 1103. Among them, the first housing 1101 includes a housing body 1, a top plate 3 and two side plates 2 oppositely arranged in the first direction. The top plate 3 and the side plates 2 are both perpendicular to the housing body 1. The air outlet 113 is formed on the top plate 3, and the water overflow hole 117 and the drain hole 115 are both formed on one of the two side plates 2. One end of the first part 1311 can be connected to the side plate 2 where the water overflow hole 117 and the drain hole 115 are formed.

[0090] Further, the bottom cover 1103 is respectively connected to the housing body 1 and the two side plates 2, and is located at the bottom end of the first housing 1101. The air inlet 112 is formed on one side of the bottom cover 1103 in the first direction. The partition rib 150 is located on the side of the bottom cover 1103 away from the air inlet 112, and the partition rib 150 can be configured as an L shape. The partition rib 150 is respectively connected to the housing body 1, the side plate 2 away from the water overflow hole 117 and the chassis, so that the partition rib 150 and the housing 110 can jointly define an assembly space 151 and can shield the electric control component 140 to prevent water from splashing onto the electric control component 140.

[0091] Further, after the first housing 1101 and the bottom cover 1103 are assembled and the internal components (such as the heating element 120, etc.) of the housing 110 are assembled, the second housing 1102 can be covered and cooperated with the first housing 1101 and the bottom cover 1103 to complete the assembly of the heater 100.

[0092] In some embodiments of the present utility model, when the water storage cavity 114 is directly used for storing water, a sealing member can be provided on the side of the first guide rib 131 close to the second housing 110. The first guide rib 131 can be hermetically cooperated with the second housing 1102 to prevent water leakage due to the gap between the first guide rib 131 and the second housing 1102.

[0093] In some embodiments of the present utility model, the housing 110 is provided with a graphene coating to improve the effect of the housing 110 radiating heat to the external environment, increase the proportion of radiant heating, and at the same time reduce the proportion of convective heating, which is beneficial to ensuring the heating effect of the heater 100 and ensuring that the housing 110 can meet the safety regulations requirements.

[0094] Combined Figures 1 - 3 , in some embodiments of the present utility model, the heater 100 further includes a support 160 located outside the housing 110. The support 160 is provided on a side wall surface of the housing 110 where the air inlet 112 is formed, and the support 160 is arranged in a dislocation manner with the air inlet 112.

[0095] Specifically, an air inlet 112 is formed on the bottom cover 1103. The support 160 can be mounted on the bottom cover 1103. The support 160 is used to support the housing 110 on the ground and keep the air inlet 112 spaced from the ground, so as to facilitate air intake into the air duct space 111. Moreover, the support 160 is arranged in a staggered manner with the air inlet 112 to prevent the support 160 from blocking the air inlet 112 and ensure the air intake effect.

[0096] Optionally, multiple supports 160 can be provided. For example: two, three, four, etc. The multiple supports 160 are spaced on the bottom cover 1103 to improve the supporting effect of the support 160 on the housing 110 and ensure the supporting stability. Of course, it can be understood that the number of supports 160 can be determined according to the sizes of the support 160 and the housing 110, and no specific limitation is made here as long as the supporting effect of the support 160 on the housing 110 is ensured.

[0097] In some embodiments of the present utility model, a driving fan can be provided inside the heater 100. The driving fan can increase the air flow convection speed, thereby improving the heating efficiency of the heater 100 for the external environment. In addition, the driving fan can reduce the temperature of the housing 110 and the proportion of external heat dissipation of the housing 110, preventing the housing 110 from being damaged due to excessive temperature.
