Referring to FIG. 1, some embodiments of the present application provide a tuyere assembly 100. The air port assembly 100 can be installed at an air inlet and an air outlet of an air supply device, and the following embodiments are described by taking the air port assembly 100 installed at the air inlet of the air supply device as an example.

As shown in fig. 1 and 2, the tuyere assembly 100 includes a holder 10, a filter 20 and a shutter 30. The bracket 10 may be installed at both sides of the tuyere in the first direction X, and the bracket 10 may include a first end 11 and a second end 12 disposed in the first direction X. The shield 30 can be interconnected with the filter 20, both the shield 30 and the filter 20 being capable of being disposed extending in the first direction X. The free end of the shield 30 is movably connected to the first end 11 and the free end of the filter 20 is movably connected to the second end 12.

Wherein the tuyere assembly 100 is switchable between a closed state and an operating state. The shield 30 may cover the tuyere when the tuyere assembly 100 is in a closed state, and the filter 20 may be located between the shield 30 and the tuyere or may be folded in the second end 12. That is, when the shutter 30 covers the tuyere, the filter 20 may be located at a side of the shutter 30 facing the tuyere and cover the tuyere. Alternatively, the filter 20 is stowed at the second end 12 when the shield 30 covers the tuyere. When the tuyere assembly 100 is in the operation state, the shielding member 30 may be folded at the first end 11, and the filtering member 20 may cover the tuyere.

Illustratively, the air inlet ceases to intake air when the air supply device ceases to operate. At this point, the tuyere assembly 100 may be in a closed state (as shown in fig. 1), the shielding member 30 may cover the air inlet, and the filter member 20 may be located at a side of the shielding member 30 facing the tuyere and cover the tuyere. Since the shutter 30 covers the air port, the shutter 30 can block outside air and dust in the air from entering the air blowing device through the air port.

When the tuyere assembly 100 is switched from the closed state to the operating state, the shielding member 30 can move towards the first end 11 and be folded at the first end 11, and the filter member 20 is driven to move. For example, a rotary shaft or the like is provided at the first end 11 to wind the shutter 30, or a receiving groove is provided at the first end 11 to receive the shutter 30 moved to the first end 11. When the shutter 30 no longer shields the tuyere, the shutter 30 stops operating. The filter 20 is also stopped by the shutter 30, and the filter 20 covers the tuyere.

Because the blower is now in operation, and the air port is not covered by the shutter 30, ambient air can pass through the filter 20 and the air port in sequence into the blower.

Similarly, when the tuyere assembly 100 is switched from the operating state to the closed state, the filter 20 can be moved toward the second end 12 and the shutter 30 is moved. When the shutter 30 completely covers the tuyere, the movement of the filter 20 is stopped. At this time, the filter 20 may be positioned at a side of the shield 30 facing the tuyere and shield the tuyere.

In summary, when the tuyere assembly 100 is switched from the closed state to the operating state, the shielding member 30 moves toward the first end 11 and drives the filter member 20 to move together until the shielding member 30 no longer covers the tuyere. When the tuyere assembly 100 is switched from the operating state to the closed state, the filter element 20 moves towards the second end 12 and moves together with the shielding element 30 until the shielding element 30 completely covers the tuyere. Providing the shutter 30 and the filter 20 in linkage improves smoothness when the tuyere assembly 100 is switched to different states.

As shown in fig. 1, in some embodiments, the tuyere assembly 100 further comprises a first driving member 40 and a second driving member 50. The first driver 40 may be located at the first end 11 and connected to the free end of the shutter 30 and the second driver 50 may be located at the second end 12 and connected to the free end of the filter 20. Wherein the first driving member 40 and the second driving member 50 operate independently.

Illustratively, when the tuyere assembly 100 is switched from the closed state to the operating state, the first driving member 40 is operated and the second driving member 50 is stopped. The first driver 40 is capable of driving the shutter 30 to move toward the first end 11 and driving the filter 20 to move through the shutter 30.

When the tuyere assembly 100 is switched from the operating state to the closed state, the first driving member 40 is operated and the second driving member 50 is stopped. The second driver 50 is capable of driving the filter element 20 toward the second end 12 and moving the shield 30 through the filter element 20.

With this arrangement, the structure of the tuyere assembly 100 can be simplified while maintaining smooth and rapid operation of the shield 30, the filter 20, etc.

It should be noted that, the first driving member 40 and the second driving member 50 may be components such as a motor, and the shielding member 30 and the filtering member 20 may be directly connected to the driving end of the driving member, or a winding member may be further disposed at the driving end of the driving member, so as to connect the shielding member 30 and the filtering member 20 with the winding member.

For example, in some examples, as shown in fig. 1, the drive ends of the first and second drive members 40, 50 may be coupled to a gearbox transmission. One end of the transmission structure may be connected to the shutter 30 and the filter 20.

In other examples, as shown in fig. 3, the driving end of the first driving member 40 is further connected to a first transmission member 41. The extending direction of the first transmission member 41 intersects with the moving direction of the shutter 30, and the first transmission member 41 and the shutter 30 are connected and can wind the shutter 30. For example, in the example shown in fig. 1, the first transmission member 41 may be a rotating shaft, and when the first transmission member 41 rotates counterclockwise, the shutter 30 moves toward the first end 11 and can be wound around the outer wall thereof by the first transmission member 41. When the first transmission member 41 rotates along the pointer, the shielding member 30 can move towards the second end 12, and the thickness of the shielding member 30 wrapped on the outer wall of the first transmission member 41 gradually decreases.

This arrangement not only facilitates the winding of the shield 30, but also reduces the space taken up by the shield 30 when it is stowed at the first end 11.

Further, as shown in fig. 4 and 6, in some embodiments, the first end 11 is further provided with a second transmission member 13. The second transmission member 13 may be located at a side of the first transmission member 41 facing the tuyere and disposed parallel to the first transmission member 41. Wherein the outer wall of the second transmission member 13 is in contact with the shielding member 30 and is capable of supporting the shielding member 30. When the shutter 30 moves towards the first end 11, friction can be generated between the shutter 30 and the second transmission member 13, and the second transmission member 13 can rotate under the action of friction. In this way, the stability of the shutter 30 when it is moved can be improved by the second transmission member 13.

Still further, referring to fig. 4, the bracket 10 is further provided with a first limiting member 14. The first limiting member 14 may be located beside the second transmission member 13. For example, in the example of fig. 1, the first limiting member 14 may be located between the first transmission member 41 and the second transmission member 13. The first limiting member 14 may protrude from the support 10 and contact with the edge of the shielding member 30 to limit the shielding member 30 in the second direction Y, so as to reduce the probability of shifting along the second direction Y when the shielding member 30 moves, thereby causing the shielding member 30 wound around the first transmission member 41 to accumulate in a certain direction and further causing deformation or damage to the shielding member 30.

As shown in fig. 5, the first end 11 of the bracket 10 may be provided with the first limiting members 14 at both sides along the second direction Y, so that the shielding member 30 may be further limited, thereby further reducing the probability of shifting and deforming along the second direction Y when the shielding member 30 moves.

With continued reference to fig. 5, in some embodiments, the first end 11 has a receiving cavity 15. The first transmission member 41 may be located within the receiving cavity 15. When the tuyere assembly 100 is in an operating state, the shielding member 30 may be wound around the outer wall of the first transmission member 41, and at least a portion of the shielding member 30 may be located in the accommodating chamber 15. In this way, not only can the space occupied by the shutter 30 wound around the first transmission member 41 be reduced to reduce the volume of the tuyere assembly 100, but also the probability of interference between the shutter 30 and other components can be reduced.

Specifically, in some embodiments, as shown in fig. 5, a plurality of buffer members 16 are further disposed in the bottom wall of the accommodating cavity 15 at intervals, all the buffer members 16 are disposed along the second direction Y and have a space with the first transmission member 41, each buffer member 16 has a recess portion recessed inwards, and the shape of the recess portion can be adapted to the shape of the first transmission member 41.

During the process of winding the shutter 30 around the first transmission member 41, the shutter 30 may pass through the recess, be in contact with the recess, and then be wound around the outer wall of the first transmission member 41. Because the shape of the recess portion is adapted to the shape of the first transmission member 41, the recess portion can help the shield 30 to be better fitted to the outer wall of the first transmission member 41, thereby improving smoothness when the shield 30 is wound up.

More specifically, as shown in fig. 3, the bracket 10 further includes a guide groove 17. The guide slot 17 may be located between the first end 11 and the second end 12. When the tuyere assembly 100 is in the closed state, the partial shutter 30 may be located in the guide groove 17 and slidably engaged with the guide groove 17. When the tuyere assembly 100 is in an operating state, a part of the filter member 20 may be located in the guide groove 17 and slidably engaged with the guide groove 17.

The shielding member 30 and the filter member 20 positioned at the tuyere are limited by the guide groove 17, so that the shielding member 30 and the filter member 20 can be limited in a plurality of different sections of the moving paths of the shielding member 30 and the filter member 20, and the probability of shifting and deforming along the second direction Y when the shielding member 30 and the filter member 20 move is maximally reduced.

In some embodiments, the free end of the filter element 20 is provided with a second stop 21 (e.g., fig. 1). The second limiting member 21 may be an inductive switch such as a micro switch. When the tuyere assembly 100 is in the operation state, the second stopper 21 may be in contact with the second transmission member 13, and then the second stopper 21 may be triggered to stop the operation of the second driving member 50. This prevents the filter 20 from moving excessively, so that the filter 20 cannot completely block the tuyere, thereby reducing the filtering effect of the filter 20.

It will be appreciated that the free end of the shield 30 may also be provided with a sensor switch similar to a microswitch, the principle of operation of which is similar and will not be described in detail here.

In some embodiments, as shown in FIG. 2, the shield 30 and the filter 20 are removably connected. For example, the shield 30 and filter 20 may be connected together by a snap-fit assembly. When any one of the shutter 30 and the filter 20 is damaged, the damaged one may be replaced to reduce the maintenance cost of the tuyere assembly 100.

Some embodiments of the present application further provide an air supply device. The air supply device includes a housing and the above-described tuyere assembly 100. Wherein the tuyere assembly 100 is installed at a tuyere of the seat body. Because the air blowing device includes the tuyere assembly 100, the air blowing device has the functions and the beneficial effects of the tuyere assembly 100 provided by the above embodiment, which are not described herein.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
