Description

Technical Field

[0001] This invention relates to the field of air volume regulation equipment technology, and in particular to an air valve device and an air outlet device. Background Technology

[0002] Currently, there are various types of air vents used in central air conditioning systems and fresh air systems on the market, and most of them are fixed vents. In order to meet the needs of some customers who want to easily adjust the air volume distributed to each room according to the size of each room in their home, so that the air volume, temperature and humidity in each room are suitable, adjustable air volume vents have also been designed.

[0003] Currently, the main adjustment methods on the market include adjustable air outlets with variable diameters and adjustable fan-shaped air outlets. However, the obstruction components of these adjustable mechanisms themselves block a large area, and the size of the air outlet is changed by means of offset rotation, etc. The area blocked by these components cannot be exposed through adjustment and cannot participate in airflow regulation. Therefore, the obstruction components have a large blocking area other than for the purpose of regulating airflow, the adjustable range is greatly limited, and the effect of reducing airflow is obvious. Summary of the Invention

[0009] The aforementioned air valve device regulates airflow by unfolding and retracting a shielding cloth. The shielding effect created when the cloth is retracted is beyond its necessary function. Because the cloth is made of flexible material, it can be largely retracted, significantly reducing the area obstructed beyond airflow regulation and greatly increasing the upper limit of the adjustable ventilation area. When obstruction is needed, the cloth can simply be unfolded as required.

[0010] In one embodiment, the operating component includes a transmission mechanism disposed within the pipe and connected in a driving connection to the shielding cloth;

[0013] The driven member can move relative to the receiving tube along the first direction under the action of an external force, so as to drive the shielding cloth to be retracted or extended from one end of the receiving tube in the first direction and change its capacity contained in the receiving tube.

[0014] In one embodiment, the transmission mechanism further includes a driving member that cooperates with the driven member. The driving member includes a rotating shaft and gear teeth disposed around the rotating shaft. The rotating shaft passes through the pipe along a second direction intersecting the first direction.

[0015] One end of the driven member extends into the receiving tube and is connected to the shielding cloth, while the other end is constructed with transmission teeth that mesh with the gear teeth along the first direction.

[0016] In one embodiment, the transmission mechanism further includes a tensioning member connected to the peripheral edge of the cover fabric and providing a tension force to drive the cover fabric to unfold.

[0017] In one embodiment, the follower is connected to the central region of the shielding fabric, and the tensioner is connected to multiple peripheral sides of the shielding fabric, applying a tension force to the shielding fabric from the central region toward the peripheral side through each connected peripheral side.

[0018] In one embodiment, the damper device further includes multiple support members, each of which is connected at one end to the wall of the pipe and at the other end to the receiving pipe, supporting the receiving pipe in the central region of the pipe.

[0019] In one embodiment, the outer surface of the pipe is provided with a plurality of guide grooves along the first direction and the side of the support member facing away from the receiving pipe in the first direction along the direction from one end connected to the wall to one end of the receiving pipe.

[0020] The tensioning element is a transmission rope, and there are multiple transmission ropes. One end of each transmission rope is connected to the driven element, and the other end is connected to the periphery of the shielding cloth along a guide groove.

[0021] In one embodiment, the operating component further includes an operating element disposed outside the pipe and operably connected to the active element.

[0022] In one embodiment, the shielding cloth is made of graphene.

For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] Please see Figures 1 to 4 An embodiment of the present invention provides a damper device 100, including a duct 10, a shielding cloth 30, and an operating component 50. A ventilation duct F extending along a first direction is formed within the duct 10. The shielding cloth 30 is made of a flexible material and is disposed within the ventilation duct F. The shielding cloth 30 can be operably driven to unfold and retract to change its shielding area on the ventilation duct F perpendicular to the first direction.

[0043] The damper device 100 can be installed in various ventilation ducts 10, fresh air unit outlets, central air conditioning outlets, etc., as long as airflow can pass through it and it can regulate the air volume. The airflow in the duct 10 flows in the first direction within the ventilation duct F, and the first direction corresponds to... Figure 3The direction perpendicular to the paper. The shielding cloth 30 is the shielding component. The shielding area of ​​the shielding cloth 30 on the ventilation duct F in the direction perpendicular to the first direction can be represented by its projected area in the first direction. The remaining unshielded area is the ventilation area. By unfolding the shielding cloth 30 through the operating component 50, the shielding area is increased, resulting in a reduction in the airflow through the air valve device 100. Conversely, by retracting the shielding cloth 30, the shielding area is reduced, resulting in an increase in the airflow through the air valve device 100. It is easy to see that the upper limit of the airflow adjustment of the shielding cloth 30 corresponds to its fully retracted state, and the lower limit corresponds to its fully unfolded state. Preferably, the shielding cloth 30 is unfolded in a plane perpendicular to the first direction, at which time the unfolding efficiency is maximized and the airflow adjustment effect is best.

[0044] The aforementioned air valve device 100 regulates airflow by unfolding and retracting the shielding cloth 30. The shielding created when the shielding cloth 30 is retracted provides additional shielding beyond its essential function. Because the shielding cloth 30 is made of flexible material, it can be retracted to a large extent, significantly reducing the shielding area beyond airflow regulation and significantly increasing the upper limit of the adjustable ventilation area. When shielding is needed, the shielding cloth 30 can be unfolded as required.

[0045] Furthermore, the operating component 50 includes a transmission mechanism 51, which is disposed within the duct 10 and is throttle-connected to the shielding cloth 30. The damper device 100 also includes a receiving tube 70 extending longitudinally along a first direction, and the shielding cloth 30 can change its capacity contained within the receiving tube 70 under the drive of the transmission mechanism 51, thereby changing its shielding area on the ventilation duct F in the direction perpendicular to the first direction.

[0046] The receiving tube 70 is used to store the covering cloth 30. When the covering cloth 30 is moved into the receiving tube 70 by the transmission mechanism 51, it is gathered by the opening of the receiving tube 70 and gradually stored inside. It is easy to see that the more covering cloth 30 is stored in the receiving tube 70, the less it is outside the receiving tube 70, and correspondingly, the covering area naturally becomes smaller.

[0047] When the shielding cloth 30 is completely contained within the receiving tube 70, the area of ​​the receiving tube 70 perpendicular to the first direction is the shielding area excluding the purpose of regulating airflow. Since the shielding cloth 30 is a flexible and thin fabric, its volume after being folded up is small. Therefore, the diameter of the receiving tube 70 can be very small, and its longitudinal length is arranged along the first direction to reduce the shielding area excluding the purpose of regulating airflow, reduce unexpected wind resistance, and thus also have lower operating noise.

[0048] Understandably, in some other embodiments, the winding can be used to gather the coils, and the unwinding can be used to unfold them, etc., which are not specifically limited here.

[0049] Specifically, the fully extended outer contour of the shielding cloth 30 is consistent with the cross-sectional shape of the ventilation duct F perpendicular to the first direction, and can be fully retracted and accommodated in the receiving tube 70 and / or fully extended and extended outside the receiving tube 70.

[0050] The shielding cloth 30 is large enough to provide a structural basis for completely blocking the ventilation duct F. When it is fully extended and unfolded outside the receiving tube 70, completely blocking the ventilation duct F, the damper device 100 is in a fully closed state (e.g., Figures 5 to 7 (As shown). When it is fully retracted and contained within the receiving tube 70, and the shielding cloth 30 no longer blocks the ventilation duct F, the damper device 100 is in the fully open state (as shown). Figures 8 to 10 (As shown). When it is neither fully extended and unfolded outside the receiving tube 70, and the shielding cloth 30 partially blocks the ventilation duct F, the air valve device 100 is in a half-open state (as shown). Figures 2 to 4 (As shown).

[0051] Furthermore, the transmission mechanism 51 includes a follower 511, at least a portion of which extends into the receiving tube 70 and is connected to the shielding cloth 30. The follower 511 is capable of moving relative to the receiving tube 70 along a first direction under the action of an external force, thereby causing the shielding cloth 30 to be extended or retracted from one end of the receiving tube 70 in the first direction and changing its capacity within the receiving tube 70.

[0052] During the movement of the driven member 511 along the first direction, the portion of it located inside the receiving tube 70 and connected to the shielding cloth 30 can drive the shielding cloth 30 to move. The shielding cloth 30 is retracted from one end of the receiving tube 70 in the first direction, and the driven member 511 moves along the first direction away from this end (i.e., Figure 2 When the middle right side moves, the shielding cloth 30 is continuously drawn into the receiving tube 70 from the opening at that end, increasing the receiving capacity.

[0053] In some embodiments, the transmission mechanism 51 further includes a driving member 513 that cooperates with the driven member 511. The driving member 513 includes a rotating shaft 5131 and gear teeth 5133 disposed circumferentially on the rotating shaft 5131. The rotating shaft 5131 passes through the pipe 10 along a second direction intersecting the first direction. One end of the driven member 511 extends into the receiving tube 70 and is connected to the shielding cloth 30, while the other end is provided with transmission teeth 5111 that mesh with the gear teeth 5133.

[0054] The transmission gear 5111 is constructed on the surface of the driven member 511 along the first direction. The driven member 511 can be, but is not limited to, a rack, a worm gear, etc. When the rotating shaft 5131 drives the gear 5133 to rotate, it can drive the driven member 511 to move along the first direction through the transmission gear 5111. The engagement of the gear 5133 with different teeth of the transmission gear 5111 is directly related to the position of the driven member 511, and thus directly related to the capacity of the shielding cloth 30. Therefore, the corresponding shielding area can be adjusted by the rotation angle of the driving member 513, that is, the rotating shaft 5131, thereby forming different air volumes.

[0055] In some other embodiments, the follower 511 can also be driven to move along the first direction by directly pulling it.

[0056] Furthermore, the operating assembly 50 also includes an operating element (not shown), which is located outside the pipe 10 and is operatively connected to the driving element 513.

[0057] In practical use, the duct 10 may connect to other equipment or have filters, sponges, etc. installed at the air outlet. Therefore, in traditional adjustment methods, these items need to be removed one by one before airflow can be adjusted. In this application, the active component 513 is installed along the duct 10 and can be easily connected to the operating component outside the duct 10. The user can rotate the active component 513 through the operating component. Since the active component 513 is located outside the duct 10, operating the operating component does not require the aforementioned removal work, which is very convenient and avoids the problem of reduced equipment lifespan caused by frequent removal work.

[0058] Understandably, in some other embodiments, the active component 513 can also be driven to rotate automatically or semi-automatically by setting a drive motor or other means.

[0059] In some embodiments, the transmission mechanism 51 further includes a tensioning member 515, which is connected to the peripheral edge of the cover cloth 30 and provides a tensioning force to drive the cover cloth 30 to unfold.

[0060] When the follower 511 moves in the first direction toward the opening of the tube containing the shielding cloth 30 (i.e. Figure 2 When the middle left moves, the shielding cloth 30 can be unfolded outside the receiving tube 70 under the tension of the tensioning member 515, the capacity of the shielding cloth 30 contained in the receiving tube 70 is reduced, and the shielding area is increased.

[0061] Furthermore, the follower 511 is connected to the central region of the shielding cloth 30, and the tensioner 515 is connected to multiple peripheral edges of the shielding cloth 30, and applies a tension force to the shielding cloth 30 from the central region to the peripheral through each connected peripheral edge.

[0062] The driven member 511 can pull the central area of ​​the shielding cloth 30 to make it retract and be housed in the receiving tube 70 under the action of the tube opening, while the tensioning member 515 applies force to the shielding cloth 30 through the edge, and the direction of the force is in all directions. In this way, the shielding cloth 30 is subjected to more even force, and can complete the retraction or unfolding work more smoothly.

[0063] The tensioner 515 is preferably evenly distributed around the shielding cloth 30 at multiple locations. The central area of ​​the shielding cloth 30 is connected to one end of the follower 511 in the first direction via a pressure cap 91.

[0064] Furthermore, the damper device 100 also includes multiple support members 80, each of which is connected at one end to the wall of the pipe 10 and at the other end to the receiving pipe 70, supporting the receiving pipe 70 in the central area within the pipe 10.

[0065] The receiving tube 70 is located in the central area of ​​the pipe 10, and can unfold the shielding cloth 30 from the center to the surrounding area, or it can retract from the surrounding area to the center to receive the shielding cloth 30.

[0066] In one embodiment, there are four supports 80 evenly arranged around the receiving tube 70. It is understood that in some other embodiments, the number of supports 80 may be three, five, etc., and no specific limitation is made here.

[0067] Furthermore, the outer surface of the pipe 10 along the first direction and the side of the support member 80 facing away from the receiving pipe 70 along the direction from one end of the connecting wall to one end of the receiving pipe 70 are constructed with multiple guide grooves D. The tensioning member 515 is a transmission rope, and there are multiple transmission ropes. One end of each transmission rope is connected to the driven member 511, and the other end is connected to the periphery of the shielding cloth 30 along a guide groove D.

[0068] Understandably, each guide groove D is composed of a guide groove D portion on the outer surface of the pipe 10 connected to a guide groove D portion of the support member 80, and the number of transmission ropes corresponds to the number of guide grooves D, with each transmission rope extending along a guide groove D.

[0069] The drive rope and the driven member 511 pull the shielding cloth 30 from its central area and its periphery, respectively. When the driven member 511 moves away from the opening of the receiving tube 70 along the first direction, it pulls the shielding cloth 30 into the receiving tube 70. One end of the drive rope connected to the shielding cloth 30 moves toward the receiving tube 70 under the drive of the shielding cloth 30, allowing the shielding cloth 30 to be received in the receiving tube 70. When the driven member 511 moves closer to the opening of the receiving tube 70 along the first direction, it can drive the drive rope to move through the end connected to the drive rope, and move the end connected to the shielding cloth 30 away from the receiving tube 70, thereby pulling the drive part out of the receiving tube 70.

[0070] Specifically, one end of all the transmission ropes is connected to one end of the driven member 511 in the first direction via a tail cap 93. In other words, the two opposite ends of the driven member 511 in the first direction are respectively connected to the shielding cloth 30 and the transmission rope.

[0071] In some other embodiments, the tensioner 515 may also be an elastic element with one end connected to the periphery of the shielding cloth 30 and the other end connected to the pipe 10, and has a tendency to contract. When the driven follower 511 is moved in a direction away from the opening into which the shielding cloth 305 enters, the follower 511 can provide a driving force that overcomes the elastic force of the elastic element.

[0072] When the follower 511 moves in the direction of the opening into which the shielding cloth 30 enters, the shielding cloth 30 unfolds outside the receiving tube 70 under the elastic force of the elastic member contraction.

[0073] In some embodiments, the material of the shielding cloth 30 is graphene.

[0074] Graphene is soft yet possesses high tensile strength, oxidation resistance, and durability. Using 0% graphene to create a 30% graphene-based covering fabric allows for thinner designs and a smaller, more compact volume. Understandably, in its…

[0075] In some embodiments, the shielding cloth 30 may also be made of nylon or other materials, and no specific limitation is made here.

[0076] The aforementioned damper device 100 allows the user to rotate the driving element 513 forward or reverse by operating the external actuator of the pipe 10, thereby driving the driven element 511 to move in the first direction. When it is away from the receiving pipe 70...

[0077] When the tube opening for receiving the shielding cloth 30 is used, the driven member 511 can pull the shielding cloth 30 through the tube opening to gather it and house it in the receiving tube 70 via the end connected to the shielding cloth 30. When the driven member 511 approaches the tube opening of the receiving tube 70 for receiving the shielding cloth 30, the driven member 511 pulls the periphery of the shielding cloth 30 through a transmission rope that can be connected to it, causing it to be released and unfolded from the receiving tube 70. Depending on the angle of the operating member, the position of the driven member 511 is different, and correspondingly, the amount of shielding cloth 30 that can be gathered in the receiving tube 70 is also different.

[0078] The cover cloth 30 can switch between being fully closed and fully open.

[0079] The present invention also provides an air outlet device, including the aforementioned air valve device 100. The air outlet device can be, but is not limited to, a fresh air unit, a central air conditioning system, etc., and the air volume is adjusted by the air valve device 100.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
