An embodiment of the present utility model provides a fan device, and in a specific embodiment of the present utility model, the fan device is a skirting line fan heater. Of course, in other embodiments, the fan device may be a cold air blowing device without a heating unit.

Fig. 1 shows a schematic overall structure of a fan device according to an embodiment of the present utility model. The fan assembly is shown in fig. 1 in a normal use orientation in which the fan assembly is positioned on the ground, and for convenience of description, the height direction of the fan assembly (i.e., the direction perpendicular to the ground when in normal use) is denoted as the Z-axis direction. The length direction of the fan is marked as the X-axis direction, and the width direction of the fan is marked as the Y-axis direction.

The fan apparatus in one embodiment of the present utility model includes a first housing 10, a second housing 20, a lifting assembly 30, and a guide assembly 40. The first housing 10 is provided with an air inlet 14. The second housing 20 is provided with an air outlet 221. The second housing 20 is nested within the first housing 10. The lifting assembly 30 is connected to the first housing 10 and the second housing 20, respectively. The second housing 20 may be driven by the lifting assembly 30 to reciprocate in a first direction with respect to the first housing 10 to protrude from the first housing 10 or to be received in the first housing 10. The guiding component 40 is disposed in a cavity formed by the first casing 10 and the second casing 20, and the guiding component 40 can guide the lifting component 30.

The first direction is, for example, the Z-axis direction in fig. 1, i.e. the height direction of the fan device. Referring to fig. 1, which is a schematic view of the second housing 20 extending from the first housing 10, the air outlet 221 is exposed outside the first housing 10, and the air flow generated from the fan device can be blown out from the air outlet 221.

Referring to fig. 2, which is a schematic view of the second housing 20 being accommodated in the first housing 10, the air outlet 221 is hidden in the first housing 10, so that dust can be prevented from entering the fan device through the air outlet 221 when the fan device is not in use. The user can be prevented from seeing the inner structure from the air outlet 221, and the appearance is more attractive. And the overall height of the fan device is reduced, so that the fan device is convenient to store and saves space.

Referring to fig. 3, which is an exploded structural view of the fan apparatus (only a partial structure is shown), the lifting assembly 30 is connected to the first housing 10 and the second housing 20, respectively. The lifting assembly 30 drives the second housing 20 away from the first housing 10 in a first direction to protrude from the first housing 10, a process called lifting of the second housing 20. The lifting assembly 30 drives the second housing 20 to approach the first housing 10 in the first direction to be received in the first housing 10, which is referred to as the lowering of the second housing 20. The guiding component 40 and the lifting component 30 are arranged together, so that the guiding component 40 plays a guiding role in driving the movement of the second shell 20 by the lifting component 30, and the blocking caused by the deviation generated in the lifting or descending process of the second shell 20 is reduced, so that the lifting is smoother.

Referring to fig. 3, the elevating assemblies 30 are provided at both ends of the fan apparatus in the length direction (X-axis direction) respectively, for example, in two groups, so that the elevation is more stable. The corresponding guiding components 40 are correspondingly arranged in two groups, and each group of guiding components 40 is correspondingly arranged in one group of lifting components 30.

The lifting lever 31 is fixedly connected with the second housing 20 and the lifting lever 31 extends in the first direction (Z-axis direction). The transmission part 32 is fixedly connected with the first housing 10, the transmission part 32 includes a screw rod 321 (refer to fig. 5), the screw rod 321 extends along a first direction and is in threaded connection with the lifting rod 31, and the lifting rod 31 can reciprocate along the first direction along with the rotation of the screw rod 321. The lifting rod 31 is, for example, hollow, and is internally provided with, for example, a nut, the nut is provided with an internal thread, the screw rod 321 is provided with an external thread, and the external thread of the screw rod 321 is meshed with the internal thread of the nut, so as to convert the rotation of the screw rod 321 relative to the nut into linear movement of the lifting rod 31. Of course, this embodiment is merely illustrative, and in other embodiments, the lifting assembly 30 may also employ a rack and pinion mechanism, a cam mechanism, etc. to achieve the reciprocating movement of the lifting rod 31.

Still further, referring to fig. 5, which is a schematic view of a part of the structure of the lifting assembly 30, the transmission portion 32 further includes a first worm wheel 322 and a second worm wheel 323. The first worm gear 322 is fixed at one end of the screw rod 321 far away from the second housing 20, and the first worm gear 322 is coaxially arranged with the screw rod 321.

The second worm wheel 323 is engaged with the first worm wheel 322, and an axis of the first worm wheel 322 is disposed to intersect with an axis of the second worm wheel 323. Specifically, the axes of the first worm wheel 322 and the second worm wheel 323 are perpendicular to each other, for example, the axis of the first worm wheel 322 is along the Z-axis direction in the drawing, and the axis of the second worm wheel 323 is along the X-axis direction in the drawing. In this way, when the second worm wheel 323 is driven to rotate around the axis along the X-axis direction, the first worm wheel 322 is driven to rotate around the axis along the Z-axis direction, and the first worm wheel 322 drives the screw rod 321 to rotate around the axis along the Z-axis direction, so that the lifting rod 31 moves along the Z-axis direction, and lifting of the second housing 20 can be realized.

Specifically, as in the above embodiment, each of the two sets of lifting assemblies 30 includes one second worm wheel 323, and the two second worm wheels 323 are respectively connected to the transmission shaft 52 and coaxially disposed with the transmission shaft 52. The output end 511 of the driving motor 51 may be connected to the first end of the driving shaft 52, and may directly drive the driving shaft 52 to rotate so as to drive the two second worm gears 323 to synchronously rotate, so as to realize that the two ends of the second housing 20 in the second direction synchronously lift, so that the lifting is balanced. Or the output end 511 of the driving motor 51 may be connected to the second worm wheel 323 connected to the first end, and by directly driving the second worm wheel 323 to rotate so as to drive the transmission shaft 52 to rotate, and driving the other second worm wheel 323 located at the second end to rotate by the transmission shaft 52, the two ends of the second housing 20 in the second direction may also be lifted synchronously.

Referring to fig. 6, in some embodiments, the second worm wheel 323 of the lifting assembly 30 (i.e., the second worm wheel 323 connected to the first end) adjacent to the driving motor 51 is sleeved on the output end 511 of the driving motor 51 and the first end of the driving shaft 52, where the output end 511 and the first end of the driving shaft 52 may be spaced apart from each other without being directly connected. The second worm wheel 323 of the other lifting assembly 30 is sleeved on a second end (not shown) of the transmission shaft 52. In other embodiments, the output end 511 of the driving motor 51 may be fixedly connected to the first end of the transmission shaft 52 through a sleeve, and the two second worm gears 323 are respectively sleeved on the first end and the second end of the transmission shaft 52.

Referring to fig. 6, in a specific embodiment, the transmission part 32 further includes, for example, a transmission part box 324, a bearing 325, a fixing member 326, and a connecting member 327, a through hole along the second direction is provided in the transmission part box 324, the bearing 325 is provided in the through hole, a second worm wheel 323 is connected with the bearing 325, one end of the first worm wheel 322 and one end of the screw rod 321 are riveted together through the connecting portion 327 and the fixing portion 326, one end of the transmission part box 324, which is close to the second housing 20, is provided with a through hole, and one end of the screw rod 321 extends out of the transmission part box 324 from the through hole.

The above-described structure can achieve the fitting connection of the screw 321, the first worm gear 322, and the second worm gear 323, but the present embodiment is not limited thereto.

In some embodiments, the guide assembly 40 includes a first guide portion 41 and a second guide portion 42 with reference to fig. 4. The first guide portion 41 is slidably connected to the second guide portion 42. In some embodiments, the second guide portion 42 may be disposed within the lift bar 31 or integrally formed with the lift bar 31, and the first guide portion 41 may be disposed on the screw 321 or integrally formed with the screw 321. Or in other embodiments, the first guiding portion 41 may be fixedly connected to the first housing 10, and the second guiding portion 42 may be fixedly connected to the second housing 20. Or in some embodiments the second guide 42 is fixedly coupled to the lift bar 31. That is, the guide assembly 40 and the lifting assembly 30 are mutually independent, so that the guide assembly 40 can be independently prepared, and the guide assembly is assembled in a screw locking mode and the like, so that the guide assembly is more convenient to prepare. Wherein, a guide slot 411 extending along the first direction is formed on one of the first guide portion 41 and the second guide portion 42, a guide rod 421 is disposed on the other of the first guide portion 41 and the second guide portion 42, and the guide rod 421 extends into the guide slot 411 and is slidably connected with the guide slot 411.

The second guiding portion 41 is fixedly connected with the second housing 20 or the lifting rod 31, so that the second guiding portion 42 can move relative to the first guiding portion 41 during the process of moving the lifting rod 31 to drive the second housing 20 to lift. In this process, the guide bar 421 slides in the guide groove 411 and is limited in sliding direction by the guide groove 411, so that the second housing 20 or the lifting bar 31 is not deviated during the lifting process, and thus the jam problem during the lifting process can be avoided.

With continued reference to fig. 4 and 7, a position monitoring assembly 60 is further provided in the fan apparatus, and the position monitoring assembly 60 is disposed corresponding to the guide slot 411, for sensing the position of the guide rod 421 in the guide slot 411. The fan apparatus also includes, for example, a control assembly, and the position monitoring assembly 60 is electrically connected to the control assembly. For example, in fig. 4, the guide bar 421 is at the top of the guide slot 411 (the end of the guide slot 411 near the second housing 20), and the second housing 20 is lifted to the highest position. Conversely, when the guide bar 421 is located at the bottom of the guide groove 411 (the end of the guide groove 411 away from the second housing 20), the second housing 20 is lowered to the lowest position. The position monitoring assembly 60 can feed back to the control assembly when the guide rod 421 is detected to be positioned at the top of the guide slot 411, and the control assembly controls the driving motor 51 to stop running so as to stop the lifting assembly 30 from driving the second shell 20 to lift; when the guide rod 421 is detected to be positioned at the bottom of the guide slot 411, the feedback is sent to the control component, and the control component controls the driving motor 51 to stop running so as to stop the lifting component 30 from driving the second shell 20 to descend.

More specifically, the position monitoring assembly 60 includes, for example, a first micro switch 61 and a second micro switch 62, which are provided at opposite ends of the guide slot 411 in the first direction, respectively. As shown in fig. 7, the first micro switch 61 is located at the top of the guide slot 411, and the second micro switch 62 is located at the bottom of the guide slot 411. The guide bar 421 contacts the first micro switch 61 when moving to the top of the guide slot 411, determines that the second housing 20 reaches the maximum elevation, and contacts the second micro switch 62 when moving to the bottom of the guide slot 411, determines that the second housing 20 reaches the lowest descent position. In other embodiments, the position monitoring assembly 60 may also employ infrared ranging sensors or the like.

The first side plate 222 and the second side plate 223 are each provided with an air outlet 221, and the air guide 23 is provided to blow out the generated air flow from the air outlets 221 dispersed from the middle to both sides, for example, a heating unit 90 (see fig. 3) is further provided in the first casing 10 to heat the generated air flow, and a function of blowing warm air can be used. When the function of blowing warm air is used, the air flow can be guided by the arrangement of the air guide piece 23 so as to quickly achieve the effect of comprehensively heating the space.

In some embodiments, referring to fig. 3 and 8, the length direction of the top plate 21 is disposed along a second direction, which is perpendicular to the third direction.
