Generally, two air valves are installed, and one of the air valves is opened for ventilation. When the ventilation volume needs to be increased, both valve actuators need to be opened at the same time for operation. However, this will lead to relatively complicated wiring methods, and time-consuming inspection and maintenance after installation. Utility Model Content

[0035] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0036] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0037] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0038] refer to Figures 1 to 4 A cavity-combined air valve according to a preferred embodiment of the utility model will be described in detail below, the cavity-combined air valve includes a valve body 10 and a driving device 20, wherein the valve body 10 includes a mounting frame 11 and a plurality of blades 12, the driving device 20 is installed on the valve body 10, the mounting frame 11 includes a connecting member 13, the connecting member 13 divides the mounting frame 11 into a control area 1101 and an open area 1102, the plurality of blades 12 are rotatably installed in the control area 1101, the plurality of blades 12 can close or open the control area 1101, and the driving device 20 can control the rotation of the plurality of blades 12 to a predetermined angle.

[0039] That is to say, under normal ventilation conditions, the driving device 20 causes the multiple blades 12 to close the control area 1101, and ventilation is performed from the side of the open area 1102. When the ventilation volume demand increases, the driving device 20 controls the multiple blades 12 to rotate, so that the control area 1101 is opened, and wind can also pass through the control area 1101. This arrangement ensures the air volume demand of the main air duct, can meet the ventilation volume demand, has a simple connection structure, and reduces costs.

[0040] It is worth mentioning that when the driving device 20 is running, it drives the blade 12 to rotate. The different rotation angles of the blade 12 result in different ventilation volumes in the control area 1101. When the blade 12 and the mounting frame 11 are perpendicular to each other, the ventilation volume in the control area 1101 is the largest.

[0041] Specifically, the connecting member 13 includes at least one baffle 131, which is installed in the installation frame 11 to separate the control area 1101 from the open area 1102, and one side of the plurality of blades 12 is installed on the baffle 131. This integrated arrangement reduces the floor space and installation space.

[0042] In another embodiment, specifically, the connecting member 13 includes two baffles 131, two buckles 132 and a locking member 133, wherein the two baffles 131 are installed in the installation frame 11, and the two baffles 131 divide the installation frame 11 into a first installation frame and a second installation frame, wherein the first installation frame is provided with a plurality of blades 12, and the second installation frame has no blades 12. The two baffles 131 are spaced apart from each other, the two buckles 132 are respectively installed on the sides of the two baffles 131 that are close to each other, and the locking member 133 is installed on the two baffles 131.

[0043] In this embodiment, the cross-sectional shape of the two buckles 132 is L-shaped. When the two buckles 132 are buckled together, the long sides of the buckles 132 are connected to the retaining edges, and the short sides of the buckles 132 are buckled with each other; and the locking member 133 is implemented as a bolt, passing through the two baffles 131 to fix the two baffles 131 in connection.

[0044] That is to say, the installation frame 11 can be integrally formed, or can be divided into a first installation frame and a second installation frame. When the operator installs the air valve on the main air duct, the blade 12 of the control area 1101 is opened or closed according to the demand for air volume. The installation method is simple, the weight of the valve body itself is reduced, and the production cost is reduced.

[0045] Furthermore, the air valve of the cavity combination further comprises a filter assembly 30, the filter assembly 30 is mounted on the mounting frame 11 of the valve body 10, wherein the filter assembly 30 comprises a filter net 31, and the filter net 31 is mounted on a side of the mounting frame 11 away from the main air duct. It is worth mentioning that in this embodiment, the net 31 has static electricity and can absorb more dust.

[0046] Furthermore, the filter assembly 30 also includes a dustproof cotton 32, which is installed between the installation frame 11 and the filter net 31, and can better filter the dust in the wind entering the main air duct, thereby improving the cleanliness of the main air duct.

[0047] Further, the air valve of the cavity combination further includes a clamping assembly 40, and the clamping assembly 40 is installed between the installation frame 11 and the filter screen 31. The clamping assembly 40 includes at least one clamping block 41 and at least one slide rail 42, wherein the clamping block 41 is installed on the filter screen 31, and the slide rail 42 is installed on the installation frame 11. In this embodiment, two clamping blocks 41 are provided, and two slide rails 42 are provided, and the two clamping blocks 41 are respectively installed on the two sides of the filter screen 31, and the two slide rails 42 are respectively installed on the two sides of the installation frame 11.

[0048] It is worth mentioning that the cross section of the block 41 is trapezoidal, the end of the block 41 with a smaller diameter is connected to the filter 31, and the slide rail 42 is adapted to the block 41, that is, the slide rail 42 is provided with a slot, and the cross section of the slot is adapted to the block 41 and is trapezoidal. In this way, when the block 41 slides in the slot of the slide rail 42, the block 41 cannot be disengaged from the slide rail 42 in the horizontal direction because the cross sections of the block 41 and the slot are trapezoidal.

[0049] The operator slides the block 41 along the slot of the slide rail 42 until the filter 31 is installed on the installation frame 11. If the filter needs to be cleaned or the air valve needs to be repaired, the operator slides the block 41 along the slot of the slide rail 42 to remove the filter 31 on the installation frame 11.

[0050] To sum up, when two air ducts converge into a main air duct, and the main air duct is normally guaranteed to have one path of gas passing through, the ventilation volume requirement is basically met, and the wind enters the main air duct through the open area 1102 of the installation frame 11. When the main air duct needs a larger air volume, the driving device 20 controls the blades 12 in the control area 1101 of the installation frame 11 to rotate to ensure the air volume requirement in the main air duct.

[0051] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
