Description

Technical Field

[0001] This utility model relates to the field of air duct technology, and in particular to an easily adjustable air duct. Background Technology

[0002] In ventilation systems, air ducts are crucial components for air transport, and precise airflow regulation is paramount. Currently, airflow regulating valves are widely used in air ducts to control airflow, with manual adjusting butterfly valves for circular ducts being a common type. These butterfly valves regulate airflow through a central rotating disc, making operation relatively simple. However, due to long-term operation of the ventilation system and the presence of dust and particulate matter in the environment, dust easily accumulates at the contact point between the disc and the duct's inner wall. Over time, the accumulated dust increases, causing the disc to become stuck during rotation, preventing adjustment at the desired angle and thus affecting the precise control of airflow within the duct. When the disc becomes stuck, it often requires opening one end of the valve body, a cumbersome operation. Furthermore, repeatedly opening the valve body can damage the duct's seal, leading to air leaks and further reducing the efficiency and performance of the ventilation system. Utility Model Content

[0003] In view of the problems existing in the above and / or existing easily adjustable air ducts, this utility model is proposed.

[0004] Therefore, the problem that this utility model aims to solve is that the butterfly plate of the air volume regulating valve in the air duct is stuck and difficult to clean.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an easily adjustable air duct, comprising a main component including a pipe, a butterfly plate disposed inside the pipe, a fixed shaft fixed inside the pipe, a rotating shaft fixed on the butterfly plate, and an adjusting component fixed on the rotating shaft;

[0006] A cleaning assembly, located on the pipe, includes a cleaning component. The cleaning component includes a fixing ring fixed to the outside of the pipe. A first annular groove is formed in the fixing ring. A slider is disposed in the first annular groove. A first rotating plate is fixed to one end of the slider. A second rotating plate is fixed to one side of the first rotating plate. A baffle is fixed on the inner wall of the first annular groove. The slider can contact the baffle. An annular ring is fixed to one end of the baffle. A through hole corresponding to the annular ring is formed in the slider. The annular ring is inserted into the through hole.

[0007] As a preferred embodiment of the easily adjustable air duct of this utility model, a first brush head is fixed at one end of the first rotating plate, and a second brush head is fixed inside the second rotating plate. The first brush head and the second brush head can be attached to the butterfly plate.

[0008] As a preferred embodiment of the easily adjustable air duct of this utility model, the slider is T-shaped, and a second annular groove is provided on the duct, wherein the slider slides within the second annular groove.

[0009] As a preferred embodiment of the easily adjustable air duct of this utility model, one end of the baffle is fixed with a curved spring, and the other end of the curved spring is fixed to one end of the slider.

[0010] As a preferred embodiment of the easily adjustable air duct of this utility model, one end of the slider is fixed with a first pull rope, and the other end of the first pull rope is fixed with a pull ring.

[0011] As a preferred embodiment of the easily adjustable air duct of this utility model, the cleaning component further includes a locking element located on one side of the slider. A first moving groove is provided on the fixing ring. The locking element includes a locking block that slides within the locking element. A spring is fixed to one end of the locking block, and the other end of the spring is fixed to the inner wall of the first moving groove. A locking groove is provided on the slider, and the locking block can engage with the locking groove.

[0012] As a preferred embodiment of the easily adjustable air duct of this utility model, one end of the locking block is inclined, and the shape of the locking groove corresponds to it.

[0013] As a preferred embodiment of the easily adjustable air duct of this utility model, the fixing ring is provided with a through groove, the first pull rope is inserted into it, and a sealing ring is fixed to the inner wall of the through groove.

[0014] As a preferred embodiment of the easily adjustable air duct of this utility model, a second pull rope is fixed on one side of the locking block.

[0015] As a preferred embodiment of the easily adjustable air duct of this utility model, the number of cleaning components is two sets, located on both sides of the butterfly plate respectively.

[0016] The beneficial effects of this utility model are as follows: By setting up a cleaning component, there is no need to cut off the air duct or open one end of the air duct valve body as in the traditional method. Users can pull the pull rope outside the air duct to move the cleaning component and directly perform dust removal on the outer ring of the butterfly plate. This simplifies the cleaning process and avoids the problem of air duct sealing damage that may be caused by opening the air duct valve body. At the same time, the cleaning component will not hinder the rotation of the butterfly plate in the duct, ensuring the continuous and stable operation of the ventilation system and improving the reliability and cleaning efficiency of the ventilation system.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1

[0029] Reference Figures 1-7This is the first embodiment of the present invention. This embodiment provides an easily adjustable air duct. The easily adjustable air duct includes a main component 100, including a pipe 101. A butterfly plate 102 is disposed inside the pipe 101. A fixed shaft 103 is fixed inside the pipe 101. A rotating shaft 104 is fixed on the butterfly plate 102. Rotating the rotating shaft 104 can drive the butterfly plate 102 to rotate around the fixed shaft 103, thereby causing the butterfly plate 102 to rotate inside the pipe 101, thereby adjusting the airflow in the pipe 101. An adjusting component 105 is fixed on the rotating shaft 104. The adjusting component 105 is used to adjust the rotation angle of the butterfly plate 102, thereby controlling the airflow in the pipe 101.

[0030] The adjusting component 105 mainly includes a handle and a locking device. Turning the handle can drive the rotating shaft 104 to rotate. The locking device is used to lock the rotation angle of the handle, thereby locking the angle of the butterfly plate 102. A locking block is provided on the handle, and a locking plate is fixed on the pipe 101. The locking plate has several slots corresponding to the locking block. When it is necessary to turn the handle, the locking block is separated from the slot, the handle is unlocked, and then the air volume can be adjusted. After the adjustment is completed, the locking block is engaged with the slot again to lock the position of the butterfly plate 102 in the pipe 101. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0031] For manually adjustable butterfly valves in circular ducts, the maximum rotation angle of butterfly plate 102 is 90 degrees. In the figure, butterfly plate 102 can be rotated clockwise to open.

[0032] The cleaning component 200, located on the pipe 101, includes a cleaning element 201. The cleaning element 201 is designed to clean the dust adhering to the outer ring of the butterfly plate 102, thereby preventing jamming when the butterfly plate 102 rotates.

[0033] The cleaning component 201 includes a fixing ring 201a fixed to the outside of the pipe 101. A first annular groove 201a-1 is provided in the fixing ring 201a. A slider 201b is provided in the first annular groove 201a-1. A first rotating plate 201c is fixed to one end of the slider 201b. A second rotating plate 201d is fixed to one side of the first rotating plate 201c. When the slider 201b slides along the first annular groove 201a-1, it can drive the first rotating plate 201c and the second rotating plate 201d to rotate synchronously.

[0034] A baffle 201e is fixed on the inner wall of the first annular groove 201a-1. The slider 201b can contact the baffle 201e. An annular ring 201f is fixed at one end of the baffle 201e. The baffle 201e is set to provide stable support for the annular ring 201f and restrict the sliding of the slider 201b. A through hole 201b-1 corresponding to the annular ring 201f is opened in the slider 201b. The annular ring 201f is inserted into the through hole 201b-1. The annular ring 201f is not a complete ring. It is cut by the baffle 201e and fixed to the two symmetrical end faces of the baffle 201e. The setting of the annular ring 201f ensures that the slider 201b can slide smoothly in the first annular groove 201a-1, thereby driving the first rotating plate 201c and the second rotating plate 201d to rotate smoothly, thereby cleaning the dust attached to the part of the butterfly plate 102 near the outer ring.

[0035] Example 2

[0036] Reference Figures 1-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, a first brush head 201g is fixed at one end of the first rotating plate 201c, and a second brush head 201h is fixed inside the second rotating plate 201d. The first brush head 201g and the second brush head 201h can be attached to the butterfly plate 102.

[0038] When the first rotating plate 201c and the second rotating plate 201d rotate, the first brush head 201g and the second brush head 201h will rotate synchronously. Since the two are in contact with the butterfly plate 102, they clean the outer edge of the butterfly plate 102, causing the attached dust to fall off, thereby preventing the butterfly plate 102 from getting stuck when it rotates.

[0039] One side of the first rotating plate 201c will also contact the inner wall of the pipe 101, and bristles are also provided on this side so as to clean the inner wall of the pipe 101.

[0040] Specifically, the slider 201b is T-shaped, and a second annular groove 101-1 is provided on the pipe 101, in which the slider 201b slides.

[0041] The T-shaped arrangement allows the slider 201b to slide within the first annular groove 201a-1 and the second annular groove 101-1 without separating from them.

[0042] Specifically, a curved spring 201i is fixed to one end of the baffle 201e, and the other end of the curved spring 201i is fixed to one end of the slider 201b. The curved spring 201i is sleeved on the outside of the annular ring 201f to ensure that the position of the curved spring 201i will not shift during the compression process.

[0043] The bending spring 201i applies a continuous pushing force to the slider 201b, causing one end face of the slider 201b to fit against one end face of the baffle 201e. The bending spring 201i is also used to enable the slider 201b to return to its initial state after completing its rotation in the first annular groove 201a-1, which is convenient for the next cleaning.

[0044] Specifically, a first pull rope 201j is fixed to one end of the slider 201b, and a pull ring 201k is fixed to the other end of the first pull rope 201j.

[0045] Pulling the pull ring 201k will move the first pull rope 201j, and the other end of the first pull rope 201j is fixed to the first pull rope 201j, thereby causing the slider 201b to slide along the first annular groove 201a-1 and rotate around the outer ring of the butterfly plate 102, thereby cleaning the baffle 201e. At this time, the bent spring 201i will be gradually compressed.

[0046] When the operator continues to pull the pull ring 201k and encounters resistance, it indicates that one-way cleaning has been completed. After that, the slider 201b is released. Under the action of the bending spring 201i, the bending spring 201i will return to its original position and push the slider 201b to move in the opposite direction in the first annular groove 201a-1 until it returns to the initial position. During this process, another cleaning will be performed.

[0047] Specifically, the cleaning component 200 also includes a locking element 202 located on one side of the slider 201b. The locking element 202 is configured to lock the initial position of the slider 201b, thereby ensuring that the slider 201b will not slide freely in the first annular groove 201a-1 when cleaning is not required.

[0048] The fixed ring 201a has a first moving groove 201a-2. The locking member 202 includes a locking block 202a that slides within the locking member 202. One end of the locking block 202a is fixed with a spring 202b, and the other end of the spring 202b is fixed to the inner wall of the first moving groove 201a-2. The spring 202b applies a continuous pushing force to the locking block 202a. When the locking block 202a is in a relaxed state, one end of the locking block 202a protrudes from the first moving groove 201a-2. The slider 201b has a locking groove 201b-2, and the locking block 202a can engage with the locking groove 201b-2.

[0049] The elastic force of the bending spring 201i is greater than that of the spring 202b.

[0050] With the cooperation of locking block 202a and locking groove 201b-2, when the two are engaged, the position of slider 201b will be locked. At this time, pulling slider 201b will not make slider 201b slide.

[0051] Specifically, one end of the locking block 202a is inclined, and the shape of the locking groove 201b-2 corresponds to it. By setting it in an inclined manner, after completing this unidirectional cleaning, the slider 201b is released. Under the action of the bending spring 201i, the bending spring 201i returns to its original state and pushes the slider 201b to move in the opposite direction in the first annular groove 201a-1. During this process, the end face of the slider 201b will first contact the inclined surface of the locking block 202a and align and squeeze, thereby compressing the spring 202b. The locking block 202a will move into the first moving groove 201a-2 without hindering the movement of the slider 201b. The locking groove 201b-2 will move synchronously with the slider 201b. When the locking groove 201b-2 and the locking block 202a are in a coaxial position, the two will engage again, and the slider 201b will return to its initial position. One end face of the slider 201b will once again fit against the baffle 201e.

[0052] At this time, the right-angled surface of the locking groove 201b-2 is in contact with the right-angled surface of the locking block 202a, and the locking block 202a will prevent the slider 201b from separating from the baffle 201e.

[0053] Example 3

[0054] Reference Figures 1-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0055] Specifically, a through groove 201a-3 is provided on the fixing ring 201a, into which the first pull rope 201j is inserted. A sealing ring 201l is fixed on the inner wall of the through groove 201a-3. The first pull rope 201j passes through the sealing ring 201l, and the sealing ring 201l is used to seal the through groove 201a-3 and the first pull rope 201j.

[0056] Specifically, a second pull rope 202c is fixed to one side of the locking block 202a for unlocking the slider 201b.

[0057] In the initial state, the locking block 202a engages with the locking groove 201b-2, and the slider 201b is locked in position. When cleaning is required, the baffle 201e is pulled to compress the spring 202b, thereby separating the locking block 202a from the locking groove 201b-2. The locking block 202a will not obstruct the movement of the slider 201b. Then, the first pull rope 201j is pulled to make the slider 201b rotate in the first annular groove 201a-1 to complete the cleaning.

[0058] Specifically, there are two sets of cleaning components 201, located on both sides of the butterfly plate 102, but they are not symmetrically distributed. Since the butterfly plate 102 in the figure opens by rotating clockwise, the two cleaning components 201 need to be in opposite positions so as not to affect the opening of the butterfly plate 102.

[0059] In use, when it is necessary to clean the dust adhering to the outer ring of the butterfly plate 102, pull the baffle 201e to compress the spring 202b, thereby separating the locking block 202a from the locking groove 201b-2. The locking block 202a will not obstruct the movement of the slider 201b. Then, pull the pull ring 201k to move the first pull rope 201j. The other end of the first pull rope 201j is fixed to the first pull rope 201j, thereby causing the slider 201b to slide along the first annular groove 201a-1, and driving the first rotating plate 201c and the second rotating plate 201d to rotate. The first brush head 201g and the second brush head 201h will rotate synchronously, thereby cleaning the outer edge of the butterfly plate 102, causing the adhering dust to fall off, and thus preventing the butterfly plate 102 from getting stuck when rotating.

[0060] When the operator continues to pull the pull ring 201k, it will be blocked, indicating that one-way cleaning has been completed. Then, release the slider 201b. Under the action of the bending spring 201i, the bending spring 201i will return to its original position and push the slider 201b to move in the opposite direction in the first annular groove 201a-1. During this process, another cleaning will be performed. The end face of the slider 201b will first contact the inclined surface of the locking block 202a and align and press, thereby compressing the spring 202b. The locking block 202a will move into the first moving groove 201a-2 without hindering the movement of the slider 201b. The locking groove 201b-2 will move synchronously with the slider 201b. When the locking groove 201b-2 and the locking block 202a are in a coaxial position, the two will engage again, and the slider 201b will return to its initial position for the next cleaning.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
