Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0024] Please refer to Figures 1-5 , a filtering mechanism of a fan coil unit in this embodiment includes a fan coil unit 1 and a segmented pipe 2 connected to the fan coil unit 1. A filtering structure for filtering the interior of the fan coil unit 1 is provided in the segmented pipe 2, so that a certain amount of dust can be filtered through the connection of the segmented pipe 2.

[0025] In this embodiment, the filtering structure includes a filter screen 3 fixedly installed on the inner wall of the segmented pipe 2 and a detector for detecting the state of dust attached to the filter screen 3. Specifically, the detector includes an infrared emitter 5 and an infrared receiver 4 fixedly installed on the left and right sides of the filter screen 3.

[0026] In specific implementation, an infrared signal is emitted by the infrared emitter 5. The infrared signal passes through the filter screen 3 and is received by the infrared receiver 4. When there is more dust attached to the surface of the filter screen 3, the infrared signal is difficult to transmit at this time, so that the detection of the dust state on the surface of the filter screen 3 can be completed through an electrical signal.

[0027] It should be noted that a warning light 6 electrically connected to the infrared receiver 4 is also fixedly installed on the top of the segmented pipe 2. By cooperating the warning light 6 with the infrared receiver 4, the dust state on the surface of the filter screen 3 can be more intuitively reflected.

[0028] In order to connect the segmented pipe 2 to the fan coil unit 1, in this embodiment, a pressure rod 7 for abutting above the fan coil unit 1 is also fixedly installed on the top of the segmented pipe 2. The number of the pressure rods 7 is two. When the two pressure rods 7 abut above the fan coil unit 1, the segmented pipe 2 and the fan coil unit 1 can be pre-fixed and connected.

[0029] In this embodiment, recessed grooves 13 are provided at both ends of the segmented pipe 2, and a sealing ring 14 that abuts against the fan coil unit 1 is embedded in the recessed grooves 13. The sealing ring 14 can improve the connection tightness of the segmented pipe 2 relative to the fan coil unit 1.

[0030] It should be noted that a limiting structure for restricting the upward movement of the segmented pipe 2 relative to the fan coil unit 1 is provided on the fan coil unit 1. By cooperating the limiting structure with the pressure rod 7, the positioning and installation of the segmented pipe 2 relative to the fan coil unit 1 can be achieved.

[0031] In this embodiment, the limiting structure includes a mounting frame 8 fixedly installed on the top of the fan coil unit 1 and a pressing plate 9 slidably connected to the mounting frame 8. The mounting frame 8 and the pressing plate 9 are arranged on both sides of the segmented pipe 2, and the opposite ends of the two pressing plates 9 are inserted into each other to improve the extension stability of the pressing plate 9.

[0032] In this embodiment, a gear 10 for pulling the pressing plate 9 to extend and move is rotatably installed inside the mounting frame 8. Tooth grooves corresponding to the gear 10 are provided on both side surfaces of the pressing plate 9. By meshing the tooth shape of the gear 10 with the pressing plate 9, the pressing plate 9 can be driven to move relative to the mounting frame 8 when the gear 10 rotates.

[0033] It should be noted that a worm gear 11 fixedly connected to the gear 10 is also rotatably installed on the top of the mounting frame 8, and a worm 12 meshing with the worm gear 11 is rotatably installed on the top of the mounting frame 8 through a bracket.

[0034] It is worth noting that the directions of the two worm gears 11 on the mounting frame 8 are opposite to reduce movement interference.

[0035] In specific implementation, the rotation of the worm 12 can drive the worm gear 11 to rotate.

[0036] In order to facilitate the rotational adjustment of the worm 12, hexagonal holes corresponding to a wrench are provided at both ends of the worm 12 in this embodiment.

[0037] In this embodiment, connecting frames 15 are fixedly installed on both sides of the filter screen 3, and the infrared emitter 5 and the infrared receiver 4 are both connected through the connecting frames 15.

[0038] The working principle of the above embodiment is as follows:

[0039] During daily use, an infrared signal is emitted from the infrared emitter 5 to the infrared receiver 4. When the surface of the filter screen 3 is covered with dust, the infrared signal cannot penetrate. At this time, the infrared receiver 4 can send an electrical signal to the warning light 6 to prompt the staff to take out the filter screen 3 for cleaning in time. The staff uses a wrench tool to drive the worm 12 to rotate. When the worm 12 rotates, it meshes with the worm wheel 11, causing the worm wheel 11 to rotate synchronously with the worm 12. When the gear 10 connected to the worm wheel 11 rotates synchronously, it can drive the pressing plate 9 to move relative to the mounting frame 8 under the rotation of the gear 10 until the two pressing plates 9 move to a position away from the upper part of the segmented pipe 2, so that the segmented pipe 2 can be directly separated from the fan coil unit 1 by lifting.

[0040] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0041] Although the embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
