[0026] The specific embodiments of the utility model will be described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0027] Please refer to Figs. 1 to 4 The air volume adjusting device is arranged on the liquid tank type filter and faces the air source, so that the air volume blowing to the liquid tank type filter can be adjusted, and the air volume of the liquid tank type filter is adjusted.

[0028] Specifically, the air volume adjusting device comprises a mounting beam 10, a support rod 40, a flow distribution plate 20 and a hollow guide pipe 30. The guide pipe 30 penetrates the mounting beam 10 in the vertical direction. The support rod 40 is arranged in the guide pipe 30 and at least partially extends out of the guide pipe 30. The flow distribution plate 20 is connected to one end of the support rod 40 extending out of the guide pipe 30. A plurality of flow distribution holes 20a are arranged on the flow distribution plate 20 and used to guide the air to the air inlet surface of the filter. The inner wall of the guide pipe 30 is provided with a first transmission part. The rod body of the support rod 40 is provided with a second transmission part. The second transmission part is in transmission connection with the first transmission part, so that the support rod 40 can drive the flow distribution plate 20 to move in the vertical direction.

[0029] According to the application, the guide pipe 30 is arranged on the mounting beam 10 in the vertical direction. The first transmission part is arranged on the inner wall of the guide pipe 30. Then, the support rod 40 penetrates the guide pipe 30 and is connected to the flow distribution plate 20. The second transmission part is arranged on the rod body of the support rod 40 and is in transmission connection with the first transmission part. When the support rod 40 is driven to rotate, the support rod 40 can move in the vertical direction relative to the guide pipe 30, thereby driving the flow distribution plate 20 to move away from or close to the air outlet in the vertical direction, so as to adjust the air volume. Compared with the traditional adjusting mode using the adjusting valve, the structure is simpler, the adjustment is more convenient, and the air volume can be adjusted in the room. The plurality of flow distribution holes 20a arranged on the flow distribution plate 20 can ensure the uniformity of the air speed and provide better use experience.

[0030] Exemplarily, the mounting beam 10 is used to be connected to the frame in the liquid tank type filter, so that the subsequent installation of the flow distribution plate 20 can be realized. In order to ensure the installation strength during the installation of the liquid tank type filter, the mounting beam 10 is made of aluminum alloy or other metal materials, but is not limited thereto.

[0031] It should be noted that the first transmission part and the second transmission part can adopt a threaded transmission mode, that is, the support rod 40 adopts a screw rod, and the inside of the guide pipe 30 is provided with an internal thread, so that when the support rod 40 is driven to rotate, the support rod 40 can move in the vertical direction relative to the guide pipe 30, thereby driving the flow distribution plate 20 to approach or move away from the mounting beam 10. For example, when it is necessary to increase the amount of wind entering the room, the support rod 40 is driven to rotate, so that the support rod 40 moves downward in the vertical direction relative to the guide pipe 30, thereby driving the flow distribution plate 20 to approach the liquid tank type filter and move away from the air source, so that more wind is blown to the liquid tank type filter, thereby allowing more wind to blow into the room; when it is necessary to reduce the amount of wind entering the room, the support rod 40 is driven to rotate, so that the support rod 40 moves upward in the vertical direction relative to the guide pipe 30, thereby driving the flow distribution plate 20 to move away from the liquid tank type filter and approach the air source, so that the wind blown by the air source is partially blocked by the flow distribution plate 20 and reduced to blow to the liquid tank type filter, thereby reducing the amount of wind blown into the room.

[0032] In addition, the flow distribution plate 20 is circular, and the plurality of flow distribution holes 20a are arranged in an array, and the shape of the flow distribution hole 20a is preferably circular, thereby further ensuring the uniformity of the wind speed.

[0033] In an embodiment, the end of the support rod 40 extending into the guide pipe 30 is provided with a notch 30a. In actual application, when it is necessary to adjust the position of the flow distribution plate 20 to realize the regulation of the amount of wind, a flathead screwdriver is inserted from the bottom of the guide pipe 30 to insert into the notch 30a, and then the flathead screwdriver is twisted to drive the support rod 40 to rotate, so that the support rod 40 moves in the vertical direction relative to the guide pipe 30, thereby driving the flow distribution plate 20 to move. That is, the notch 30a provided at the end of the support rod 40 extending into the guide pipe 30 is to facilitate personnel to twist the support rod 40 with a screwdriver, so as to control the movement of the support rod 40.

[0034] In an embodiment, the support rod 40 is provided with an abutting portion at an end thereof extending out of the guide pipe 30, the middle portion of the flow diffuser plate 20 is provided with a through hole for the support rod 40 to pass through, and a locking member 60 is sleeved on the support rod 40 and can be adjusted along the axial direction of the support rod 40. When the flow diffuser plate 20 is fixed on the support rod 40, the abutting portion abuts against the surface of the flow diffuser plate 20 away from the mounting beam 10, and the locking member 60 abuts against the surface of the flow diffuser plate 20 facing the mounting beam 10. That is, when the flow diffuser plate 20 is fixed on the support rod 40, the end of the support rod 40 not provided with the abutting portion is first passed through the through hole of the flow diffuser plate 20 until the abutting portion abuts against the surface of the flow diffuser plate 20 away from the mounting beam 10, and then the locking member 60 is sleeved on the support rod 40 and screwed to make the locking member 60 continuously approach the flow diffuser plate 20 until the locking member 60 abuts against the surface of the flow diffuser plate 20, at which time the flow diffuser plate 20 is fixed on the support rod 40. The structure is simple, the flow diffuser plate 20 is convenient to disassemble and replace, and the disassembly and replacement are convenient.

[0035] In an embodiment, a connecting nut 80 and a sealing member 90 are further included. The connecting nut 80 is embedded in the end of the mounting beam 10 away from the flow diffuser plate 20, and at least part of the connecting nut 80 extends into the guide pipe 30. The sealing member 90 is threadedly connected in the connecting nut 80. In this way, by embedding the connecting nut 80 in the mounting beam 10 and making part of the connecting nut 80 extend into the guide pipe 30, and then connecting the sealing member 90 in the connecting nut 80, the air flow after being affected by the flow diffuser plate 20 can be prevented from entering the guide pipe 30, thereby reducing the loss of air flow.

[0036] In actual use, in order to avoid the flow diffuser plate 20 closely abutting against the mounting beam 10 when moving downward along the vertical direction, so that the flow diffuser plate 20 cannot play a role, the position of the flow diffuser plate 20 moving downward is usually limited. In this regard, in an embodiment, a limiting frame 50 is further included. The limiting frame 50 is fixed at the end of the mounting beam 10 close to the flow diffuser plate 20, the flow diffuser plate 20 is located outside the limiting frame 50, and the end of the support rod 40 extending out of the guide pipe 30 passes through the limiting frame 50 and is connected with the flow diffuser plate 20. That is, the position of the flow diffuser plate 20 moving downward is limited by the limiting frame 50 fixed at the end of the mounting beam 10 close to the flow diffuser plate 20, which can effectively avoid the flow diffuser plate 20 closely abutting against the mounting beam 10, and ensure that the air flow can be blown to the liquid tank type filter after being affected by the flow diffuser plate 20.

[0037] In an embodiment, the limiting frame 50 includes a first side plate 51, a top plate 52 and a second side plate 53 connected in sequence. The first side plate 51, the top plate 52 and the second side plate 53 surround a through space A, and the end of the support rod 40 extending out of the guide pipe 30 is located in the through space A and passes through the top plate 52.

[0038] In an embodiment, a guide sleeve 70 is embedded in the middle portion of the top plate 52, and extends into the penetrating space A and towards the mounting beam 10. In this way, the guide sleeve 70 can be used to guide the penetrating of the support rod 40, so that the support rod 40 can be quickly and accurately penetrated through the fixing frame and the guide tube 30.

[0039] In an embodiment, the first side plate 51 and the second side plate 53 are outwardly bent to form a bent edge 54, and the bent edge 54 is provided with a first mounting hole 54a. The mounting beam 10 is provided with a second mounting hole 10a near one end of the mounting beam 10, which is matched with the first mounting hole 54a. That is, when the limiting plate is fixed to the mounting beam 10, the limiting frame 50 is first placed on the mounting beam 10, so that the bent edge 54 on the first side plate 51 and the second side plate 53 is in contact with the surface of the mounting beam 10, and at this time, the first mounting hole 54a on the bent edge 54 is aligned with the second mounting hole 10a. Then, a fastener (such as a bolt) is sequentially penetrated through the first mounting hole 54a and the second mounting hole 10a, so as to complete the fixing of the limiting frame 50 on the mounting beam 10.

[0040] The embodiment of the present disclosure also provides a liquid tank type filter comprising the air volume adjusting device in the above embodiments.

[0041] According to the liquid tank type filter of the embodiment of the present disclosure, the air volume adjusting device is adopted, and the technical effects are consistent with those of the air volume adjusting device, which will not be repeated here.

[0042] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
