Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a fan and a cooking appliance. Background Art

[0002] Cooking appliances such as induction cookers are gaining increasing popularity and recognition among consumers due to their advantages, including fast heating, lack of open flames, safety, and convenience. Induction cookers utilize high-frequency alternating current (AC) passing through a coil, generating a high-frequency, fluctuating magnetic field. This high-frequency, fluctuating magnetic field generates eddy currents at the bottom of a metal pot placed on the induction cooker, heating the food inside.

[0003] During the operation of the induction cooker, internal heating elements such as coil disks and IGBTs will generate heat. Therefore, in order to prevent the internal elements from overheating and being damaged, a fan is usually configured to dissipate the heat of the internal heating elements in a timely manner.

[0004] In related technologies, fans draw in air and blow it toward the panel, using wind pressure to push it toward the coil disk and IGBT heat sinks to dissipate heat from the heating elements. However, the amount of air blown toward the heating elements by wind pressure is relatively small, resulting in poor heat dissipation and difficulty achieving high-power heating. Utility Model Content

[0005] The present application provides a fan and a cooking appliance, which can solve the problem that the heat dissipation effect of the heating element in the cooking appliance is poor, making it difficult to achieve high-power heating of the cooking appliance.

[0006] In one aspect, the present application provides a fan, comprising:

[0007] The fan blade body, along the axial direction of the fan blade body, one side of the fan blade body is the air inlet end, and the other side of the fan blade body is the air outlet end;

[0008] The support member includes an integrally connected support portion and a first air guide portion, the support portion is arranged at the air outlet end of the fan blade body, and the fan blade body is rotatably connected to the support portion, the first air guide portion is arranged on one side of the support portion, and the first air guide portion extends from one end of the support portion toward the air inlet end.

[0009] The fan provided herein can guide airflow through the first air guide portion of the support member. The first air guide portion can direct as much airflow from the air outlet as possible toward the heating element within the cooking appliance, thereby reducing airflow losses at the heating element and ensuring sufficient airflow to the heating element, thereby improving heat dissipation efficiency from the heating element.

[0010] Furthermore, the support member of the embodiment of the present application can also function as a fixing member for the fan blades. The support member can be directly fixed to the interior of the cooking appliance via the support portion. Therefore, while the support member can guide the airflow, it can also be used to fix the fan blades, which helps reduce the number of parts, simplify the fan structure, and improve assembly efficiency.

[0011] According to one embodiment of the present application, the first air guide portion extends in an arc shape from the air outlet end to the air inlet end.

[0012] The first air guide portion extends in an arc shape from the air outlet end along the outer circumference of the fan blade body to the air inlet end. The first air guide portion can guide the airflow to increase the wall attachment effect. The airflow can flow along the inner wall of the first air guide portion and adhere closely to the inner wall of the first air guide portion. Therefore, the airflow can be more effectively guided to the heating element through the arc-shaped inner wall of the first air guide portion, thereby improving the heat dissipation effect of the cooking appliance and helping to achieve high-power heating of the cooking appliance.

[0013] Furthermore, the arc-shaped inner wall of the first air guide portion can reduce the resistance of the airflow to reduce the attenuation of the airflow velocity, thereby helping to guide the airflow to the heating element and improving the heat dissipation effect of the cooking appliance.

[0014] According to one embodiment of the present application, the first air guide portion extends from the air outlet end to the air inlet end at a right angle.

[0015] In an embodiment of the present application, the first air guide portion may include a horizontal air guide plate and a vertical air guide plate, wherein the horizontal air guide plate may be located at the air outlet end to prevent the airflow from continuing to flow upward. At this time, the airflow may flow along the circumference of the fan blade under the action of the horizontal inner wall of the horizontal air shield. Part of the airflow flows toward the heating element, and the other part of the airflow flows in the direction of the vertical air guide plate. Since the vertical air guide plate is located on the side of the fan blade and opposite to the heating element, when the airflow flows toward the vertical air guide plate, the vertical air guide plate can prevent the airflow from continuing to flow, so that the airflow flows in the direction of the heating element opposite to the vertical air guide plate, thereby achieving heat dissipation treatment for the heating element.

[0016] According to one embodiment of the present application, the first air guide portion extends linearly from the air outlet end to the air inlet end.

[0017] In the embodiment of the present application, since the first air guide portion can be disposed on the exterior of a portion of the fan blade body, the first air guide portion can extend in an inclined straight line from the air outlet end to the air inlet end. The airflow generated during the rotation of the fan blade body can flow along the linear inner wall of the first air guide portion toward the air outlet end. Part of the airflow can flow toward the heating element, and part of the airflow can be directed toward the heating element under the action of the first air guide portion, thereby increasing the amount of airflow flowing to the heating element and further improving the heat dissipation effect.

[0018] According to one embodiment of the present application, the support portion includes a connecting portion, which extends toward the fan blade body along the axial direction of the fan blade body, and the fan blade body is rotatably connected to the connecting portion.

[0019] The connecting portion can be used to secure the fan blade to the support portion, thereby achieving a fixed connection between the fan blade and the support. Furthermore, during use of the cooking appliance, the fan blade remains in a rotating state. Therefore, securing the fan blade to the support portion via the connecting portion can be used to improve the overall strength of the support. This can, on the one hand, improve the reliability of the connection between the fan blade and the support, ensuring normal use of the fan blade. On the other hand, it can also reduce the possibility of deformation of the support, which could affect the airflow effect and thus the heat dissipation effect of the heating element.

[0020] According to one embodiment of the present application, the supporting portion includes a fixing portion for fixing the fan, the fixing portion is located at the air outlet end of the fan blade body, and the fixing portion is arranged on both sides of the connecting portion.

[0021] In the embodiment of the present application, the first air guide portion can be located on a side of the fixed portion away from the heating element to direct the airflow from the air outlet toward the heating element. The fixed portion, the first air guide portion, and the connecting portion can be an integral structure. Therefore, when the fan blades are fixed to the connecting portion, a fan is formed. The fan can be installed in the cooking appliance via the fixed portion, simplifying the fan installation process.

[0022] Specifically, after the fan blades are connected to the support member to form a fan assembly, the fan assembly can be secured within the cooking appliance via the support member's fixing portion. Therefore, the fan can be secured via the fan's fixing portion without requiring any other structure. This simplifies the fan's structure, reducing the number of parts and simplifying assembly and maintenance. Furthermore, it helps conserve space within the cooking appliance.

[0023] According to one embodiment of the present application, the connecting portion protrudes from the surface of the fixing portion facing the fan blade body, and the outer wall of the connecting portion and the first air guide portion form a flow guide space.

[0024] The surface of the connecting portion protruding from the fixing portion can be used to connect to the fan blade body, so the surface of the connecting portion protruding from the fixing portion can form a flow guide space above the fan blade body. The outer wall of the connecting portion and the inner wall of the first air guide portion can form a flow guide space with a guiding function, and air can flow along the outer wall of the connecting portion and the inner wall of the first air guide portion toward the heating element.

[0025] According to one embodiment of the present application, the support member further includes a second air guide portion, which is arranged at an end of the first air guide portion away from the support portion and extends toward the air inlet end.

[0026] The second air guide portion is disposed at an end of the first air guide portion away from the first air guide portion, and the second air guide portion may be located around a portion of the fan blade body. The second air guide portion can be used to prevent the airflow introduced by the fan blade body from flowing away from the heating element, thereby allowing more airflow and stronger wind force to blow toward the heating element, thereby improving the heat dissipation effect of the heating element and maintaining the normal operation of the cooking appliance.

[0027] According to one embodiment of the present application, along the axial direction of the fan blade body and pointing in the direction of the air inlet end, the end surface of the second air guide portion away from the first air guide portion extends beyond the fan blade body.

[0028] By arranging the second air guide portion so that the end face thereof is away from the first air guide portion and extends beyond the lower end face of the fan blade body, the airflow generated by the fan blade body can be guided to the first air guide portion under the action of the second air guide portion, and then guided to the heating element through the first air guide portion.

[0029] On the other hand, the present application provides a cooking utensil comprising:

[0030] A housing, wherein the housing is provided with an air inlet area and a heating area;

[0031] The fan described in any of the above embodiments is fixed to the shell through the fixed mounting portion of the support member, the air inlet end of the support member is opposite to the air inlet area, and the first air guide portion of the support member is used to guide the airflow at the air outlet end to the heating area.

[0032] The fan includes a blade body and a support member. During installation, the blade body and the support member can be installed as a whole, which helps to reduce parts and simplify the installation process.

[0033] In addition to the technical problems solved by the embodiments of the present invention described above, the technical features that constitute the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions, other technical problems that can be solved by the fan and cooking utensils provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific implementation methods.

[0051] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0052] The exemplary embodiments will be described in detail here, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0053] Cooking appliances, such as induction cookers, are commonly used heating devices and can be used with cookware. For example, an induction cooker may include a panel, a housing, and a coil. The panel and housing form a relatively enclosed cavity, shielding the internal power board, coil, and other live components during operation.

[0054] The power board is electrically connected to the coil disk, controlling its opening and closing. During operation, high-frequency current flowing through the coil disk generates numerous closed magnetic fields. These magnetic lines of force cut through the cookware, generating numerous small eddy currents that heat the cookware placed on the panel. During use, the cookware is placed on the panel of the cooking appliance, and the cooking appliance can be used to cook the ingredients within.

[0055] The power board of a cooking appliance is equipped with an IGBT (Insulated Gate Bipolar Transistor) module, a filter circuit, a rectifier bridge, and other functional modules. During operation, the IGBT module is prone to heat generation. The IGBT module is typically equipped with a heat sink. Heat generated by the IGBT module can be dissipated through the heat sink, which has a large surface area.

[0056] Therefore, to prevent overheating of heating components such as coil disks and IGBT modules, which could affect proper operation, cooking appliances are often equipped with fans. These fans draw in air and direct it toward the panel, where it then uses wind pressure to dissipate heat from the components by directing it toward the heat sinks of the coil disks and IGBT modules. However, the amount of air delivered to the heating components by this wind pressure is relatively small, resulting in poor heat dissipation and making it difficult to achieve high-power heating.

[0057] Based on the above technical problems, the applicant has improved the structure of the existing fan. In the embodiment of the present application, the first air guide portion of the support member can have a guiding effect on the airflow. The first air guide portion can guide as much of the airflow from the air outlet as possible to the heating element in the cooking utensil, so as to reduce the airflow loss at the heating element and ensure that sufficient airflow flows to the heating element, thereby helping to improve the heat dissipation efficiency of the heating element. In addition, the support member of the embodiment of the present application can also have the function of fixing the fan blade body. The support member can be directly fixed to the inside of the cooking utensil through the support portion. Therefore, the support member can also be used to fix the fan blade body while being able to guide the airflow, which is beneficial to reduce the number of parts, simplify the structure of the fan, and improve assembly efficiency.

[0058] The fan and cooking appliance provided in the present application will be described below with reference to the accompanying drawings and in combination with specific embodiments.

[0059] See also Figures 1 to 6 As shown, the fan 100 of the embodiment of the present application may include a blade body 110 and a support member 120 .

[0060] Along the axial direction X of the fan blade 110, one side of the fan blade 110 is the air inlet end 110a, and the other side of the fan blade 110 is the air outlet end 110b. During the rotation of the fan blade 110, air can enter from the air inlet end 110a and flow toward the air outlet end 110b.

[0061] The support member 120 may include an integrally connected support portion 121 and a first air guide portion 124. The support portion 121 may be disposed at the air outlet end 110b of the fan body 110, and the fan body 110 may be rotatably connected to the support portion 121. The first air guide portion 124 may be disposed on one side of the support portion 121, with the end of the first air guide portion 124 away from the support portion 121 extending toward the air inlet end 110a.

[0062] It should be noted that the support portion 121 and the first air guide portion 124 are integrally connected, wherein the integral connection may mean that the support portion 121 and the first air guide portion 124 can be connected by an integral forming process such as integral bending, mold forming, or by a method that is not easy to disassemble such as welding, crimping, and riveting, so that the support member 120 can remain stable during the rotation of the fan blade body 110.

[0063] In the embodiment of the present application, since the first air guide portion 124 is arranged on one side of the support portion 121, and the end of the first air guide portion 124 away from the support portion 121 extends toward the air inlet end 110a, part of the first air guide portion 124 can be located at the air outlet end 110b of the fan blade body 110, and the inner wall of the first air guide portion 124 can guide the airflow at the air outlet end 110b to the heating elements 300 such as the coil disk 310 and the heat sink 320 of the IGBT module, thereby improving the heat dissipation efficiency of the heating elements 300 and ensuring the normal operation of the cooking appliance 10.

[0064] The fan blade body 110 is rotatably connected to the support portion 121. Therefore, when the support member 120 is fixed in the cooking utensil, the fan blade body 110 can be fixedly installed, thereby reducing the number of parts, simplifying the structure of the fan, and improving assembly efficiency.

[0065] In some examples, the support member 120 can be fixed to a structure such as the housing 200 or the panel 400 of the cooking appliance 10. Specifically, the fan blade 110 can be fixed to the housing 200 of the cooking appliance 10 via the support member 120. The housing 200 may include an upper cover and a lower cover 210. Therefore, the support member 120 can be connected to at least one of the upper cover and the lower cover 210. Alternatively, the support member 120 can be connected to the panel 400 of the cooking appliance 10, which is not specifically limited in the present embodiments.

[0066] In some examples, the fan blade 110 and the support member 120 may be fixed by, but not limited to, snap connection, screw connection, or connection via an adapter. The fan blade 110 may be rotatably connected to the support member 120. The support member 120 remains stationary relative to the cooking appliance 10.

[0067] In some possible implementations, see Figure 1 and Figure 2 As shown, the first air guide portion 124 can cover a portion of the exterior of the fan blade body 110 .

[0068] It should be noted that this application will be described using the example of the air inlet end 110a being located below the air outlet end 110b. Part of the first air guide portion 124 can be located at the air outlet end 110b and opposite the air inlet end 110a, while another part of the first air guide portion 124 can be opposite the heating element 300. Therefore, after the airflow enters the support member 120 from the air inlet end 110a, the part of the first air guide portion 124 located at the air outlet end 110b can prevent the airflow from continuing to flow upward, while the part of the first air guide portion 124 opposite the heating element 300 can prevent the airflow from flowing away from the heating element 300. Thus, the first air guide portion 124 can guide the airflow so that it flows toward the air outlet end 110b.

[0069] In some possible implementations, see Figure 1 and Figure 2 As shown, the first air guiding portion 124 extends from the air outlet end 110b to the air inlet end 110a in an arc shape.

[0070] In the embodiment of the present application, the first air guide portion 124 can extend in an arc shape from the air outlet end 110b along the outer circumference of the fan blade body 110 toward the air inlet end 110a. Therefore, the first air guide portion 124 can guide the airflow and enhance the wall adhesion effect. The airflow can flow along the inner wall of the first air guide portion 124 and closely adhere to the inner wall of the first air guide portion 124. The arc-shaped inner wall of the first air guide portion 124 can more effectively guide the airflow toward the heating element 300, thereby improving the heat dissipation effect of the cooking appliance 10 and facilitating high-power heating of the cooking appliance 10.

[0071] In the embodiment of the present application, the first air guide portion 124 extends in an arc shape toward the inner wall of the fan blade body 110. The arc-shaped inner wall of the first air guide portion 124 can reduce the resistance of the airflow and reduce the attenuation of the airflow speed, thereby helping to guide the airflow to the heating element and improve the heat dissipation effect of the cooking appliance 10.

[0072] In some practicable embodiments, the first air guiding portion 124 extends from the air outlet end 110b to the air inlet end 110a at a right angle (not shown).

[0073] In an embodiment of the present application, the first air guide portion 124 may include a horizontal air guide plate and a vertical air guide plate, wherein the horizontal air guide plate may be located at the air outlet end 110b to prevent the airflow from continuing to flow upward. At this time, the airflow may flow along the circumference of the fan blade body 110 under the action of the horizontal inner wall of the horizontal air shield. Part of the airflow flows toward the heating element 300, and the other part of the airflow flows in the direction of the vertical air guide plate. Since the vertical air guide plate is located to the side of the fan blade body 110 and opposite to the heating element 300, when the airflow flows toward the vertical air guide plate, the vertical air guide plate can prevent the airflow from continuing to flow, so that the airflow flows in the direction of the heating element 300 opposite to the vertical air guide plate, thereby achieving heat dissipation treatment for the heating element 300.

[0074] In some practicable embodiments, the first air guiding portion 124 extends linearly from the air outlet end 110b to the air inlet end 110a (not shown).

[0075] In the embodiment of the present application, since the first air guide portion 124 can be disposed outside a portion of the fan blade body 110, the first air guide portion 124 can extend in an inclined straight line from the air outlet end 110b to the air inlet end 110a. The airflow generated during the rotation of the fan blade body 110 can flow along the linear inner wall of the first air guide portion 124 toward the air outlet end 110b. Part of the airflow can flow toward the heating element 300, and part of the airflow can be directed toward the heating element 300 under the action of the first air guide portion 124, thereby increasing the amount of airflow flowing to the heating element 300 and further improving the heat dissipation effect.

[0076] In some possible implementations, see Figures 1 to 4 As shown, the support portion 121 may include a connecting portion 123. Along the axial direction X of the blade body 110, the connecting portion 123 may extend toward the blade body 110, and the blade body 110 may be rotatably connected to the connecting portion 123.

[0077] In the embodiment of the present application, the connecting portion 123 can be used to fix the fan blade 110 to the support portion 121, thereby achieving a fixed connection between the fan blade 110 and the support member 120. Furthermore, during use of the cooking utensil 10, the fan blade 110 remains in a rotating state. Therefore, fixing the fan blade 110 to the support portion 121 via the connecting portion 123 can be used to improve the overall strength of the support member 120. On the one hand, it can improve the connection reliability between the fan blade 110 and the support member 120, ensuring the normal use of the fan blade 110. On the other hand, it can also reduce the possibility of deformation of the support member 120, which may affect the air guide effect and thus the heat dissipation effect of the heating element 300.

[0078] In some examples, the fan blade 110 can be rotatably connected to the connecting portion 123 via an adapter shaft. The connecting portion 123 can be provided with a bearing. The bearing is coupled to the rotating shaft so that the connecting portion 123 is less likely to shake during the rotation of the fan blade 110, thereby keeping the support member 120 stationary.

[0079] In some achievable ways, participate Figure 1 and Figure 2 As shown, the support portion 121 may further include a fixing portion 122 for fixing the fan 100. The fixing portion 122 may be located at the air outlet end 110b of the fan blade 110. The fixing portion 122 may be provided on both sides of the connecting portion 123.

[0080] In the embodiment of the present application, the first air guide portion 124 can be located on a side of the fixing portion 122 away from the heating element 300 to guide the airflow from the air outlet end 110b toward the heating element 300. The fixing portion 122, the first air guide portion 124, and the connecting portion 123 can be an integral structure. Therefore, when the fan blade body 110 is fixed to the connecting portion 123, the fan 100 is formed. The fan 100 can be installed in the cooking appliance 10 via the fixing portion 122, thereby simplifying the installation process of the fan 100.

[0081] Specifically, after the fan blades 110 and the support member 120 are connected to form the fan 100 as a whole, the fan 100 can be fixed to the cooking appliance 10 via the fixing portion 122 of the support member 120. Therefore, during the process of fixing the fan 100, it can be fixed via the fixing portion 121 of the fan 100, without the need to use other structures to fix the fan 100. On the one hand, this simplifies the structure of the fan 100, thereby reducing the number of parts and simplifying assembly and maintenance. On the other hand, it also helps to save internal space of the cooking appliance 10.

[0082] In some examples, there may be two fixing portions 122. The two fixing portions 122 may be radially opposed to each other along the fan blade 110. The two fixing portions 122 may be used to abut or overlap the internal structure of the cooking appliance 10 to secure the fan 100. It is readily understood that the two fixing portions 122, radially opposed to each other along the fan blade 110, can provide uniform and stable support for the fan blade 110 and the support member 120.

[0083] In some examples, the fixing portion 122 may be provided with a mounting hole. The fan 100 may be fixed to the cooking appliance 10 via a fastener. For example, the fastener may pass through the mounting hole provided on the fixing portion 122 and be connected to a structure such as the housing 200 or the panel 400 of the cooking appliance 10.

[0084] In some achievable ways, participate Figure 1 、 Figure 2 and Figure 4 As shown, the connecting portion 123 may protrude from the surface of the fixing portion 122 facing the fan blade body 110. The outer wall of the connecting portion 123 and the first air guide portion 124 may form a flow guide space.

[0085] In the embodiment of the present application, the surface of the connecting portion 123 protruding from the fixing portion 122 can be used to connect to the fan blade body 110. Therefore, the surface of the connecting portion 123 protruding from the fixing portion 122 can form a guide space above the fan blade body 110. The outer wall of the connecting portion 123 and the inner wall of the first air guide portion 124 can form a guide space with a guiding function, and air can flow along the outer wall of the connecting portion 123 and the inner wall of the first air guide portion 124 toward the heating element 300.

[0086] In some examples, the connection portion 123 may be, but is not limited to, a columnar structure.

[0087] In some possible implementations, see Figure 1 、 Figure 2 and Figure 4 As shown, the support member 120 may further include a second air guide portion 125. The second air guide portion 125 may be disposed at an end of the first air guide portion 124 away from the support portion 121 and extend toward the air inlet end 110a.

[0088] In the embodiment of the present application, the second air guide portion 125 can be disposed at an end of the first air guide portion 124 away from the first air guide portion 124. The second air guide portion 125 can be located around a portion of the fan blade body 110. The second air guide portion 125 can be used to prevent the airflow introduced by the fan blade body 110 from flowing away from the heating element 300, so that more airflow and stronger wind force are blown toward the heating element 300, which is beneficial to improving the heat dissipation effect of the heating element and maintaining the normal operation of the cooking appliance 10.

[0089] In some examples, the second air guide portion 125 can be integrally connected to the first air guide portion 124. The first air guide portion 124, the second air guide portion 125, and the support portion 121 are integrally connected.

[0090] In some possible implementations, see Figure 2 and Figure 4 As shown, along the axial direction X of the fan blade body 110 and pointing to the direction of the air inlet end 110a, the end surface of the second air guide portion 125 away from the first air guide portion 124 can extend beyond the fan blade body 110.

[0091] Downward along the axial direction X of the fan blade body 110, by setting the second air guide portion 125 away from the end face of the first air guide portion 124 and extending beyond the lower end face of the fan blade body 110, the airflow generated by the fan blade body 110 can be guided to the first air guide portion 124 under the action of the second air guide portion 125, and guided to the heating element 300 through the first air guide portion 124.

[0092] The present application also provides a cooking utensil 10. Figures 3 to 6 As shown, the cooking appliance 10 may include a housing 200 and the fan 100 of any of the above-described embodiments.

[0093] The housing 200 is provided with an air inlet area 210a and a heating area. During rotation of the fan blade 110, air from the external environment is drawn into the cooking appliance 10 through the air inlet area 210a, forming an airflow. For example, the air inlet area 210a may include multiple through-holes that communicate with the external environment. Heat-generating components 300, such as the coil disk 310, IGBT module, and heat sink 320, which are prone to generating heat during operation of the cooking appliance 10, are located within the heating area.

[0094] The fan 100 can be fixed to the housing 200 via a support member 120. The air inlet end 110a of the fan blade 110 can correspond to the air inlet area 210a of the housing 200, and the airflow from the air outlet end 110b can be directed to the heat generation area within the cooking appliance 10 by the first air guide portion 124 of the support member 120. Specifically, the airflow from the air outlet end 110b can correspond to the coil disk 310 and the heat sink 320 of the IGBT module by the first air guide portion 124.

[0095] Under the guiding action of the first air guide portion 124 and the second air guide portion 125, most of the airflow inside the support member 120 can be blown toward the heating area inside the shell 200. Therefore, most of the airflow acts on the heating area, which can dissipate heat for the heating element 300 in the heating area, which is beneficial to improving the heat dissipation efficiency of the heating element 300.

[0096] In some possible implementations, see Figure 5 and Figure 6 As shown, the housing 200 may include an upper cover and a lower cover 210. For example, the fan 100 may be fixed to the lower cover 210. The lower cover 210 may be provided with support columns 211 corresponding to the fixing portions 122. The support member 120 includes a support portion 121, and the two fixing portions 122 of the support portion 121 may overlap the support columns 211. The support member 120 is fixed to the support columns 211 of the lower cover 210 using a locking member.

[0097] Therefore, during installation of the fan 100, the blade body 110 and support member 120 can be installed as a single unit, reducing the number of parts and simplifying the installation process. Specifically, the two fixing portions 122 of the support member 120 can be aligned with the two support columns 211 on the lower cover 210, and then locked with a locking member to achieve the fixed installation of the fan 100. The assembly method between the fan 100 and the lower cover 210 is simple, and the installation direction facilitates the application of force, which helps to reduce the difficulty of assembly and maintenance.

[0098] The support column 211 can protrude from the upper surface of the lower cover 210 to support the fan 100 at a certain height. After the fan 100 is fixed to the support column 211, there is a gap between the fan blade 110 and the upper surface of the lower cover 210 to prevent the fan blade 110 from interfering with the lower cover 210 during rotation.

[0099] Along the axial direction X of the fan blade body 110 , the distance between the lower end surface of the second air guide portion 125 and the lower cover 210 may be less than or equal to the distance between the fan blade body 110 and the lower cover 210 .
