The utility model is described below with reference to specific embodiments in conjunction with the accompanying drawings:

referring to fig. 1 to 13, an embodiment of the present utility model discloses an air duct assembly, which includes a housing 100, a heating element 200 and a toggle element 300. The air duct assembly may be used in the cooling fan heater 700, and of course, may be used in other air conditioning devices, and the utility model is not limited thereto.

The housing 100 is a basic component of the air duct assembly of the present utility model, the housing 100 may provide a mounting base for at least some other components of the air duct assembly of the present utility model, the housing 100 has an air duct 110 therein, and correspondingly, the housing 100 also has an air inlet 120 and an air outlet 130 in communication with the air duct 110, and air flow may enter the air duct 110 through the air inlet 120 and be exhausted through the air outlet 130. The heat generating element 200 is disposed on the housing 100, so that the heat generating element 200 can be fixed, and the heat generating element 200 can move relative to the housing 100. Specifically, the heat generating element 200 has a first state and a second state, wherein, in the case that the heat generating element 200 is in the first state, the heat generating element 200 is located in the air duct 110, so that the air flow passing through the air duct 110 can pass through the heat generating element 200, and can be heated after contacting with the heat generating element 200, so that the air flow output through the air outlet 130 of the housing 100 is a heated hot air flow, and the air duct assembly of the present utility model can output hot air; in the case that the heat generating element 200 is in the second state, the heat generating element 200 is located outside the air duct 110, and thus, the air flow passing through the air duct 110 does not blow the heat generating element 200 directly, so that the air flow is not heated by the heat generating element 200 directly contacting, and thus, the temperature of the air flow outputted through the air outlet 130 of the housing 100 is relatively low. Therefore, by switching the heat generating member 200 between the first state and the second state, the air duct assembly of the present utility model may output hot air or normal temperature air having a relatively low temperature, and it should be understood that, when the air duct assembly of the present utility model is combined with the air conditioning apparatus, the air outlet 130 of the air duct assembly may also output cool air in the case that the heat generating member 200 is in the second state.

It should be understood that, in the related art, in order to make the heating element 200 movable, the driving device connected to the heating element 200 may be provided to drive the heating element 200 to move, but the driving device has a complex structure, which is not beneficial to be integrated in the air duct assembly, and meanwhile, the driving device has a high cost, which may result in a high overall cost of the air duct assembly.

Therefore, the air duct assembly of the present application is provided with the stirring member 300, the stirring member 300 is connected with the heating member 200, the stirring member 300 can be forced to drive the heating member 200 to move, specifically, when a user applies a force to the stirring member 300, the stirring member 300 can drive the heating member 200 to move to the first state or the second state under the condition of being forced, therefore, the air duct assembly of the present application can adjust the state of the heating member 200 by applying an external force to the stirring member 300, so that the heating member 200 can be conveniently adjusted between the first state and the second state, and meanwhile, the structure of the air duct assembly can be simplified, so that the structure of the air duct assembly is relatively simple, and the cost is relatively low.

In the air duct assembly provided by the embodiment of the application, the stirring piece 300 is connected with the heating piece 200, and the stirring piece 300 can drive the heating piece 200 to switch between the first state and the second state after being stressed, so that the air duct assembly can output hot air or cold air, and further the air duct assembly has heating and heat dissipation functions. Through making stir 300 atress drive heating element 200 switch between first state and second state for the overall structure of wind channel subassembly is relatively simple, and the structure of stirring 300 is simpler relative drive arrangement simultaneously, makes stir 300 easily with heating element 200 and casing 100 assembly, stir the preparation cost of 300 and be cheaper relative drive arrangement, makes the overall cost of wind channel subassembly reducible.

In some embodiments, it should be understood that the air inlet 120 of the housing 100 in the present application determines the direction of the air flow into the air duct 110 of the housing 100, and the air outlet 130 of the housing 100 determines the direction of the air flow exiting the air duct assembly. In order to make the effect of the air duct assembly of the present application for outputting hot air better, in the case that the heat generating element 200 is in the first state, the heat generating element 200 may be disposed opposite to at least one of the air inlet 120 and the air outlet 130 of the housing 100. Specifically, when the heat generating element 200 is opposite to the air inlet 120 of the housing 100, the air flow passing through the air inlet 120 may contact the heat generating element 200, so that the air flow may be sufficiently heated; when the heat generating element 200 is opposite to the air outlet 130 of the housing 100, the air flow flowing through the air duct 110 may contact the heat generating element 200 before being discharged through the air outlet 130, so that the air flow finally discharged through the air outlet 130 may also contact the heat generating element 200 to be heated; when the heating element 200 is opposite to the air inlet 120 and the air outlet 130 of the housing 100, the air flow entering through the air inlet 120 and the air flow finally discharged through the air outlet 130 can contact with the heating element 200, so that the temperature of the hot air finally output by the air duct assembly is higher, and the air duct assembly has a better heating effect.

Specifically, in the case that the heating element 200 is opposite to the air inlet 120 and the air outlet 130 of the housing 100, the air inlet 120 and the air outlet 130 of the housing 100 may be opposite to each other, so that the air duct 110 in the housing 100 is a straight air duct 110, and therefore, the air resistance of the air flow in the process of passing through the air duct 110 of the housing 100 is smaller, the air flow can pass through the air duct 110 more efficiently, and finally, the air speed of the hot air or the cold air output through the air outlet 130 is faster. In addition, in other embodiments, the air inlet 120 and the air outlet 130 of the housing 100 may be arranged in a staggered manner, and accordingly, the air duct 110 of the housing 100 is of a curved or bent structure, and the heating element 200 may be provided with a special-shaped structure, so that the heating element 200 may be opposite to the air inlet 120 and the air outlet 130 at the same time, and the arrangement manner of the air inlet 120 and the air outlet 130 of the housing 100 is not limited.

In some embodiments, in order to make the overall structure of the air duct assembly of the present application more compact and have better appearance consistency, the housing 100 may further be provided with the escape cavity 140 in communication with the air duct 110, and when the heat generating element 200 is in the second state, the heat generating element 200 is located in the escape cavity 140, so that the heat generating element 200 is located in the housing 100 when the heat generating element 200 is in the first state or the second state, thereby preventing the heat generating element 200 from being exposed outside the housing 100 and preventing a user from being scalded due to accidental touching of the heat generating element 200. Specifically, the cavity shape of the avoidance cavity 140 of the housing 100 is adapted to the heat generating element 200, so that the avoidance cavity 140 can just accommodate the heat generating element 200, and the heat generating element 200 has a smaller gap with the inner wall of the avoidance cavity 140, so that the avoidance cavity 140 is more compact in structure, the heat generating element 200 can move smoothly, and finally the overall structure of the housing 100 is more compact. In addition, it should be further understood that, in the present application, the avoiding cavity 140 is offset from the air inlet 120 and the air outlet 130 of the housing 100, so that the airflow entering the air duct 110 through the air inlet 120 is prevented from flowing into the avoiding cavity 140 as much as possible, so as to reduce the loss of the airflow, and the flow velocity of the airflow finally output by the air duct assembly of the present application is less damaged.

In some embodiments, in order to enable the heat generating element 200 of the present application to switch between the first state and the second state, specifically, the heat generating element 200 may be switched between the first state and the second state by rotating the heat generating element 200, it should be understood that the heat generating element 200 may rotate with a rotation center axis as a reference, and a moving range of the heat generating element 200 during rotation is smaller than a moving range of the heat generating element 200, so that a space for moving the heat generating element 200 in the housing 100 may not be set too large, and thus the structural design of the housing 100 may be more compact. In addition, it should be further understood that when the heat generating element 200 is rotatably connected with the housing 100, the rotatably connected connection portion of the heat generating element 200 and the housing 100 also plays a role in assembling the heat generating element 200 with the housing 100, so that the housing 100 does not need to be separately provided with a structure for assembling with the heat generating element 200, thereby achieving the purpose of simplifying the structures of the housing 100 and the heat generating element 200.

In some embodiments, the toggle member 300 of the present application can move along a first direction or a second direction after being stressed, in which case the toggle member 300 can drive the heat generating member 200 to switch to a first state when moving along the first direction, and in which case the toggle member 300 can drive the heat generating member 200 to switch to a second state when moving along the second direction, wherein the first direction and the second direction are opposite to each other. It should be understood that, the first direction and the second direction are both straight lines, so that the moving track of the stirring member 300 is a straight line track, so that the moving track of the stirring member 300 is simpler, and the movable connection structure of the casing 100, the heating member 200 and the stirring member 300 can be simpler, so as to achieve the purpose of simplifying the structure of the air duct assembly of the present application.

In addition, it should be further understood that, since the first direction and the second direction are opposite to each other, the moving range of the toggle member 300 in the first direction and the second direction is smaller, so that the air duct assembly of the present application can be compact to some extent.

In some embodiments, to simplify the connection structure of the toggle member 300 and the heat generating member 200, the first direction and the second direction may be both disposed parallel to the rotation direction of the heat generating member 200. Specifically, the heat generating element 200 may be configured to include a heat generating body 210, a positioning portion 220 and a driving portion 230, where the heat generating body 210 is a body portion of the heat generating element 200, heat can be generated after the heat generating body 210 is energized, both the positioning portion 220 and the driving portion 230 are connected with the heat generating body 210, where the positioning portion 220 is rotatably connected with the housing 100, so that the heat generating element 200 may be integrally rotatably connected with the housing 100, specifically, a positioning hole disposed opposite to each other may be opened on the housing 100, two ends of the positioning portion 220 may be respectively inserted into the positioning holes of the housing 100, and the positioning portion 220 is in clearance fit with the positioning holes, so that the positioning portion 220 may rotate in the positioning hole, and when the heat generating element 200 rotates, the positioning portion 220 rotates with the rotation center. The driving portion 230 may be disposed in contact with the toggle member 300, and when the toggle member 300 is forced to move along the first direction or the second direction, the toggle member 300 may contact with the driving portion 230 and push the driving portion 230 to generate displacement in the first direction or the second direction, so that the driving portion 230 may rotate relative to the positioning portion 220.

It should be understood that the moving track of the driving portion 230 is a circular arc track, so that the driving portion 230 can generate displacement in the first direction and the direction perpendicular to the first direction, that is, when the driving portion 230 receives the first direction, the second direction or the force perpendicular to the first direction and the second direction, the driving portion 220 can rotate relative to the positioning portion 220, so that the toggle member 300 can apply the force in the first direction or the second direction to the driving portion 230 when moving in the first direction or the second direction, so that the driving portion 230 can rotate in the clockwise direction or the counterclockwise direction, thereby achieving the purpose of rotating the driving portion 230, and finally achieving the purpose of rotating the heating body 210, so that the heating body 210 can rotate into the air duct 110 or rotate out of the air duct 110.

Specifically, the positioning portion 220 of the present application may be configured as an opening formed on the heat generating body 210, and the housing 100 may be configured with a protrusion structure corresponding to the opening formed on the heat generating body 210, and the protrusion structure may be embedded in the opening of the heat generating body 210, so that the heat generating body 210 may rotate relative to the protrusion structure in the housing 100. Alternatively, the positioning portion 220 may be further configured as a protruding structure connected to the heat generating body 210, an opening corresponding to the protruding structure on the heat generating body 210 may be formed in the housing 100, and the protruding structure may be embedded in the opening of the housing 100, so that the heat generating body 210 may also rotate relative to the housing 100. The protruding structure may in particular be provided as a shaft structure.

In some embodiments, in order to make the process of driving the heating element 200 by the stirring element 300 to rotate more stable, the stirring element 300 may be provided with a limiting groove 321, wherein the driving portion 230 may be disposed in the limiting groove 321, and the limiting groove 321 of the stirring element 300 may limit the driving portion 230, so that the driving portion 230 is always located in the limiting groove 321 in the rotating process of the driving portion 230, and thus, the contact effect between the driving portion 230 and the stirring element 300 is more reliable, and the driving portion 230 is prevented from being separated from the stirring element 300. Specifically, in the case that the toggle member 300 moves along the first direction, an inner wall of one side of the limiting slot 321 abuts against the driving portion 230, so that the toggle member 300 can push the driving portion 230 to move along the second direction; under the condition that the toggle member 300 moves along the second direction, the inner wall of the other side of the limiting groove 321 abuts against the driving portion 230, so that the toggle member 300 can push the driving portion 230 to move along the second direction. The limiting groove 321 may be configured to be in transition fit or clearance fit with the driving portion 230, so that the limiting groove 321 and the driving portion 230 are assembled conveniently, and the resistance between the driving portion 230 and the limiting groove 321 is not excessive, so that the toggle member 300 moves smoothly along the first direction and the second direction, and the heat generating member 200 rotates smoothly.

Of course, it should also be understood that the driving portion 230 in the present application may be configured as a slot structure formed in the heat generating body 210, and accordingly, the toggle member 300 may be configured with a physical structure that is matched with the slot structure of the heat generating body 210, and the physical structure may be disposed in the slot structure of the heat generating body 210, and the toggle member 300 may also be moved to drive the heat generating member 200 to move through the matching of the physical structure and the slot structure.

In some embodiments, it should be understood that the movement track formed by the driving portion 230 after rotating around the positioning portion 220 is an arc, so that the area formed by the connection line between the two ends of the movement track of the arc of the driving portion 230 and the positioning portion 220 is a sector area, which is the active area of the driving portion 230, and the active range of the driving portion 230 is within the active area. The limiting groove 321 of the stirring member 300 can be arranged along the radial direction of the movable area, so that when the stirring member 300 drives the driving portion 230 to rotate around the positioning portion 220, the driving portion 230 not only can generate displacement in the first direction or the second direction, but also can move along the extending direction of the limiting groove 321, thereby the driving portion 230 is always positioned in the limiting groove 321 in the process of rotating around the positioning portion 220, and the limiting groove 321 can always limit the driving portion 230, so as to prevent the driving portion 230 from being separated from the stirring member 300.

In addition, in order to make the driving part 230 and the stirring member 300 convenient to be assembled and disassembled, the stirring member 300 may be further provided with a notch 322 communicated with one end of the limiting groove 321, and when the stirring member 300 is installed in the housing 100, the driving part 230 of the heating member 200 may be aligned with the notch 322 of the stirring member 300, and the heating member 200 is pushed so that the driving part 230 may slide into the limiting groove 321, thereby achieving the purpose of installing the driving part 230 in the limiting groove 321 of the stirring member 300, and when the driving part 230 needs to be separated from the stirring member 300, the driving part 230 may slide out from the notch 322 of the stirring member 300 by pulling the heating member 200. Therefore, by providing the notch 322 in the toggle member 300, which is in communication with the limiting groove 321, the driving portion 230 and the toggle member 300 can be assembled and disassembled conveniently.

In some embodiments, in order to allow the user to conveniently operate the toggle 300 to move the toggle 300 in the first direction or the second direction, at least a portion of the toggle 300 may be extended out of the housing 100, so that the user may conveniently observe the position of the toggle 300 and the position of the toggle 300 after moving, so that the user may conveniently adjust the toggle 300 and learn the state of the heat generating element 200.

The width dimension in the stirring groove 150 of the shell 100 can be matched with the upper end and the lower end of the stirring piece 300, so that the stirring groove 150 can limit the stirring piece 300, the stirring piece 300 can only move along the first direction or the second direction and can not move along the direction intersecting the first direction, the stirring piece 300 can be more stable and reliable in the moving process along the first direction or the second direction, and the stirring piece 300 is prevented from deflecting in the moving process.

In some embodiments, in order to make the toggle member 300 more stable when disposed in the housing 100 and further prevent the toggle member 300 from separating from the driving portion 230, the air duct assembly of the present application is further provided with a pressing plate 400.

The pressing plate 400 is opposite to one side inner wall of the casing 100, at least part of the stirring piece 300 is arranged between the pressing plate 400 and one side inner wall of the casing 100, so that opposite sides of a part of the stirring piece 300 between the pressing plate 400 and one side inner wall of the casing 100 can be opposite to one side inner wall of the pressing plate 400 and one side inner wall of the casing 100 respectively, and thus the purpose of limiting the stirring piece 300 can be achieved by the pressing plate 400 and one side inner wall of the casing 100, and the range where the stirring piece 300 is located is always located between the pressing plate 400 and one side inner wall of the casing 100.

Specifically, at least part of opposite sides of the toggle member 300 may contact with the platen 400 and one side inner wall of the housing 100 or have a smaller gap, so that the platen 400 and one side inner wall of the housing 100 may play a role of limiting the toggle member 300 and simultaneously reduce resistance generated by movement of the toggle member 300. The inner wall of one side of the shell 100 can be provided with a shell 100 limit rib, one side of the pressing plate 400 opposite to the stirring piece 300 can be provided with a pressing plate 400 limit rib, the directions of the shell 100 limit rib and the pressing plate 400 limit rib are opposite, and at least part of the stirring piece 300 is positioned between the shell 100 limit rib and the pressing plate 400 limit rib, so that the stirring piece 300 can be limited.

In some embodiments, the toggle member 300 of the present application may specifically include a limiting plate 310 and a lever 320, where one end of the lever 320 may be connected to the limiting plate 310, the lever 320 may also be in contact with the heat generating member 200, and specifically, the limiting slot 321 of the toggle member 300 is disposed on the lever 320, so that the driving portion 230 may be disposed in contact with the lever 320. Wherein the limiting plate 310 is installed between the pressing plate 400 and one side inner wall of the case 100, and thus the limiting plate 310 is limited to an area between the pressing plate 400 and one side inner wall of the case 100. The end of the deflector rod 320 away from the limiting plate 310 can be arranged on the pressing plate 400 in a penetrating manner, specifically, a through hole 410 for the deflector rod 320 to penetrate through can be formed in the pressing plate 400, the through hole 410 can extend along the moving direction of the deflector member 300, so that the part of the deflector rod 320 penetrating into the through hole 410 of the pressing plate 400 can move along the through hole 410, the purpose of limiting the deflector rod 320 can be achieved by the through hole 410 of the pressing plate 400, the moving direction of the deflector member 300 is further limited, and deflection of the deflector member 300 in the moving process is prevented.

In some embodiments, the toggle 300 of the present application may further include a toggle 350, where the toggle 350 is located outside the housing 100, and one end of the toggle 350 may extend into the housing 100 to connect with the limiting plate 310, so that when a user needs to toggle the toggle 300, the toggle 350 may be implemented by toggling. The toggle 350 and the limiting plate 310 may be detachably connected, so when the toggle 300 is assembled, after the limiting plate 310 and the toggle 310 are both assembled in the housing 100, the toggle 350 and the limiting plate 310 are assembled from the outside of the housing 100, so that the toggle 300 is convenient to be assembled.

In some embodiments, the toggle member 300 of the present application may further be provided with a buckle 330, wherein the buckle 330 is disposed on the lever 320, and the buckle 330 is elastically connected to the lever 320, so that the buckle 330 can move relative to the lever 320 when being stressed, and the buckle 330 can return to a natural state when no longer being stressed. Specifically, an elastic connection structure may be disposed between the buckle 330 and the lever 320, or the buckle 330 itself is made of an elastic material, so that the buckle 330 can be elastically deformed relative to the lever 320. When the toggle 300 is assembled with the pressing plate 400, the toggle 320 needs to be passed through the through hole 410 of the pressing plate 400, in this process, the buckle 330 can be passed through the through hole 410 of the pressing plate 400 together with the toggle 320, in the case that the buckle 330 is located in the through hole 410, the inner wall of the through hole 410 can press the buckle 330 to make the buckle 330 approach to the toggle 320, so that the buckle 330 can pass through the through hole 410 of the pressing plate 400 together with the toggle 320, after the buckle 330 passes through the through hole 410 of the pressing plate 400, the buckle 330 is not pressed by the inner wall of the through hole 410 of the pressing plate 400 any more, the buckle 330 can be restored to the natural state under the action of the elastic restoring force, in the case that the buckle 330 is in the natural state, the buckle 330 can be dislocated with the through hole 410 of the pressing plate 400, so that when the toggle 320 is stressed to have the trend of reversely moving away from the pressing plate 400, the buckle 330 can abut against the pressing plate 400, thus limiting the trend of continuously moving the toggle 320, so that the toggle 320 cannot be separated from the pressing plate 400.

When the user actively needs to separate the shift lever 320 from the pressing plate 400, the buckle 330 may be actively pressed so that the buckle 330 moves to be opposite to the perforation 410 of the pressing plate 400, so that when the user pulls the shift lever 320, the buckle 330 passes through the perforation 410 of the pressing plate 400 together with the shift lever 320, and the shift lever 320 is separated from the pressing plate 400. The buckle 330 may further be provided with a guiding surface, and when the buckle 330 contacts with the opening of the through hole 410, the guiding surface of the buckle 330 may contact with a corner of the opening of the through hole 410, so as to guide the buckle 330 to deform under the action of the inner wall of the through hole 410.

In some embodiments, in order to further limit the driving lever 320 to cooperate with the through hole 410 of the pressing plate 400, a driving lever 320 limit rib may be further disposed on the driving lever 320, where the driving lever 320 limit rib is located in the through hole 410 of the pressing plate 400, and the driving lever 320 limit rib may contact two opposite inner walls of the through hole 410, so that the inner walls of the through hole 410 serve the purpose of limiting the driving lever 320.

In some embodiments, in order to make the temperature of the cool air output by the air duct assembly of the present application relatively lower, the air duct assembly may further include a switch, wherein the switch is electrically connected to the heat generating element 200, and the switch may control the heat generating element 200 to be turned on or off. When the heat generating element 200 is in the first state, the heat generating element 200 can be turned on by the switch, so that the heat generating element 200 can generate heat to heat the air flow in the air duct 110; under the condition that the heating element 200 is in the second state, the heating element 200 can be turned off through the switch, so that the heating element 200 does not generate heat any more, and therefore the air flow passing through the air duct 110 is not heated by the heat generated by the heating element 200, so that the temperature of the cold air output by the air duct assembly is relatively lower, and the energy consumption of the air duct assembly can be reduced.

Specifically, the above-mentioned switch may employ the micro switch 500, and it should be understood that the micro switch 500 is a contact mechanism having a micro contact interval and a snap action mechanism, performing a switching operation with a predetermined stroke and a predetermined force, and is covered with a housing, and the outside of the housing is provided with a switch of a driving lever, and the micro switch 500 is called a sensitive switch because the contact interval of the switch is relatively small. The micro switch 500 is provided with an elastic contact, when the button is pressed, the contact sags, the elastic structure of the micro switch 500 is compressed, the micro switch 500 is opened, and after the button is not pressed any more, the elastic structure of the micro switch 500 is restored to deform, so that the button is restored to the initial position, and the micro switch 500 is closed.

The micro switch 500 of the present application may be disposed on the platen 400, and thus, the position of the micro switch 500 within the housing 100 is relatively fixed. It should be understood that, during the process of switching the heating element 200 between the first state and the second state, the toggle member 300 moves along the first direction or the second direction, so that the relative position relationship between the toggle member 300 and the pressing plate 400 is variable, and thus the relative position relationship between the toggle member 300 and the micro switch 500 is variable. During the process of switching the heating element 200 from the second state to the first state, the stirring element 300 can move along the first direction and move to the first position when the heating element 200 is switched to the first state, and when the stirring element 300 is in the first position, the stirring element 300 can press the contact of the micro switch 500 to enable the micro switch 500 to be in the open state, and at the moment, the heating element 200 is turned on; during the process of switching the heating element 200 from the first state to the second state, the stirring element 300 can move along the second direction and move to the second position when the heating element 200 is switched to the second state, and when the stirring element 300 is in the second position, the stirring element 300 is separated from the contact of the micro switch 500, so that the micro switch 500 is in the closed state, and at the moment, the heating element 200 is closed. Therefore, when the toggle member 300 drives the heating member 200 to switch between the first state and the second state, the heating member 200 can be automatically controlled to be opened and closed, so that a user does not need to separately control the heating member 200 to be opened or closed, and finally, the air duct assembly of the application is convenient to operate.

In some embodiments, in order to make the toggle member 300 capable of opening or closing the micro switch 500, the toggle member 300 may further include a trigger portion 340, where the trigger portion 340 is disposed on the limiting plate 310, and specifically is located on a plate surface on a side opposite to the pressing plate 400 of the limiting plate 310, and in the case that the heating member 200 is in the first state, the toggle member 300 is in the first position, where the trigger portion 340 is opposite to the micro switch 500, and the trigger portion 340 presses against the micro switch 500, so that the micro switch 500 is opened; in the second state of the heat generating element 200, the toggle element 300 is at the second position, and the trigger portion 340 is dislocated from the micro switch 500, so that the trigger portion 340 cannot act on the micro switch 500, and the micro switch 500 is in the initial state, i.e. the closed state. Specifically, the trigger portion 340 may be provided with a holding plane 341 and a departure plane, where the holding plane 341 and the departure plane are disposed in connection, and the trigger plane is disposed parallel to the first direction, such that the trigger plane is a plane opposite to the first direction, and the trigger plane 342 has an angle with the first direction, such that the trigger plane 342 is an inclined plane opposite to the first direction.

In the process that the heating element 200 is switched from the second state to the first state, the trigger plane 342 is firstly contacted with the micro switch 500, when the micro switch 500 passes through the trigger plane 342, the micro switch 500 is contacted with the holding plane 341 again, in the process that the micro switch 500 is contacted with the trigger plane 342, the degree of compression of the elastic structure in the micro switch 500 is gradually increased, when the micro switch 500 moves to the tail end of the trigger plane 342 relative to the trigger plane 342, the compression degree of the elastic structure in the micro switch 500 is maximum, at the moment, the micro switch 500 is started, and when the micro switch 500 is contacted with the holding plane 341, the micro switch 500 can be kept in an open state all the time. By providing the trigger plane 342, the trigger portion 340 can be guided to move relative to the micro switch 500, so that the micro switch 500 is smoothly opened. In the process that the heating element 200 is switched from the first state to the second state, the micro switch 500 can be moved from contact with the holding plane 341 to contact with the triggering plane 342, and in the process that the micro switch 500 passes through the triggering plane 342, the compression force applied to the elastic structure in the micro switch 500 is gradually reduced, and the elastic structure is gradually restored to deform, so that when micro switch can be closed.

In some embodiments, the air duct assembly of the present application further includes a protective housing 510, where the protective housing 510 is covered on the micro switch 500, the protective housing 510 can protect the micro switch 500, and the protective housing 510 is further elastically connected to the pressing plate 400, so that the toggle member 300 can achieve the purpose of pressing the micro switch 500 by pressing the protective cover, and the elastic connection of the protective cover and the pressing plate 400 can increase the resistance of the toggle member 300 when pressing the micro switch 500, so that the situation that the heating member 200 is turned on or turned off by mistake due to the user touching the toggle member 300 by mistake can be prevented to a certain extent.

In some embodiments, in order to further stabilize the relative positional relationship between the pressing plate 400 and the toggle member 300, the air duct assembly of the present application may further include an elastic support 600, wherein the elastic support 600 may be disposed between the toggle member 300 and the pressing plate 400, and both ends of the elastic support 600 are respectively supported on the toggle member 300 and the pressing plate 400, so that the pressing plate 400 or the toggle member 300 is prevented from approaching or separating from each other due to an external force to a certain extent. Specifically, one end of the elastic support 600 may be fixedly connected to the pressing plate 400, so that the elastic support 600 may be fixedly installed, and the other end of the elastic support 600 may contact and abut against the limiting plate 310, so that the elastic support 600 between the pressing plate 400 and the limiting plate 310 is always in a compressed state, and the restoring deformation force of the elastic support 600 may reject the limiting plate 310, thereby preventing the spacing between the limiting plate 310 and the pressing plate 400 from being too small. In the process of moving the limiting plate 310 relative to the pressing plate 400, one end of the elastic supporting member 600 abutting against the limiting plate 310 can also move relative to the limiting plate 310.

In some embodiments, it should be appreciated that when the toggle member 300 is switched between the first position and the second position, the toggle member 300 may further pass through the third position, and the third position may be disposed between the first position and the second position, and in particular, the third position may be disposed at an intermediate position between the first position and the second position, so that the toggle member 300 may pass through the third position regardless of whether the heat generating member 200 is switched from the first state to the second state or from the second state to the first state. In the process that the toggle member 300 is switched from the third position to the first position, the heating member 200 may gradually switch to the first state, in this process, the length of the elastic support member 600 may gradually increase, so a side plate surface of the limiting plate 310 against the elastic support member 600 may be an inclined surface, and the extrusion force applied during the movement of the elastic support member 600 relative to the limiting plate 310 may gradually decrease, so a component force of the restoring deformation force of the elastic support member 600 may drive the limiting plate 310 to move along the first direction, and the toggle member 300 may be more conveniently moved to the first position in cooperation with the driving force of the user driving the toggle member 300, thereby the heating member 200 is more effectively and conveniently switched to the first state; in the process of switching the toggle member 300 from the third position to the second position, the heating member 200 may gradually switch to the second state, in this process, the length of the elastic support member 600 may gradually increase, so a side surface of the limiting plate 310 against the elastic support member 600 may be an inclined surface, and the extrusion force applied during the movement of the elastic support member 600 relative to the limiting plate 310 may gradually decrease, so a component force of the restoring deformation force of the elastic support member 600 may drive the limiting plate 310 to move along the second direction, and the toggle member 300 may be more conveniently moved to the second position in cooperation with the driving force of the user driving the toggle member 300, thereby the heating member 200 is more effectively and conveniently switched to the second state.

Specifically, the side surface of the limiting plate 310 facing the pressing plate 400 may be configured as a wave structure, the middle portion of the side surface is convex, the sliding surface 311 of the two side areas is concave, and the sliding surface 311 may be a cambered surface, or may be an inclined surface, where when the elastic supporting member 600 abuts against the middle convex portion of the limiting plate 310, the toggle member 300 is located at the third position, and when the elastic supporting member 600 abuts against the two side concave portions of the limiting plate 310, the toggle member 300 is located in the process of switching from the third position to the first position or the second position.

In some embodiments, to make the process of switching the toggle 300 between the first position and the second position smoother, the transition between the two sliding surfaces 311 of the limiting plate 310 may be achieved by making the transition smoother. Specifically, when the sliding surfaces 311 are curved surfaces or inclined surfaces, the inclination of the two sliding surfaces 311 in the opposite directions may be gradually reduced, so that the portions where the two sliding surfaces 311 approach each other may be gradually gentle, and thus, the rate of change of the decrease in length of the elastic support 600 gradually decreases when the elastic support 600 moves from the first position to the third position, and the rate of change of the decrease in length of the elastic support 600 gradually decreases when the elastic support 600 moves from the second position to the third position, so that the elastic support 600 moves more easily across the third position to the first position or the second position.

Of course, in other embodiments, in order to make the toggle member 300 more comfortable during the process of switching between the first position and the second position, the middle protruding portion of the limiting plate 310 may be configured as a guiding plane 312, when the elastic support member 600 is located on the guiding plane 312, the toggle member 300 is located in the third position, and the guiding plane 312 is in arc-shaped transitional connection with the sliding surfaces 311 recessed on two sides of the limiting plate 310, so that the elastic support member 600 moves more smoothly relative to the limiting plate 310, and therefore, in the case that the toggle member 300 is located in the third position, the elastic support member 600 may move a distance relative to the limiting plate 310, during this process, the length of the elastic support member 600 may remain unchanged, and after the elastic support member 600 slides out of the guiding plane 312, the length of the elastic support member 600 may only increase. In addition, a plane having an arc surface may be provided on the limiting plate 310 instead of the guide plane 312.

Therefore, when the heat generating element 200 is in the first state, the heat generating element 200 may be opposite to the air outlet side of the fan 700, so that the air flow output by the fan 700 may be directly heated through the heat generating element 200; when the heating element 200 is in the second state, the heating element 200 can be arranged in a staggered manner with the air outlet side of the fan 700, so that the air flow output by the fan 700 cannot pass through the heating element 200, the air flow cannot be heated, the air duct component can output cold air, in addition, the heating element 200 cannot cause extra wind resistance to the air flow output by the fan 700, and the wind force of the air flow output by the air duct component is strong.
