Description

Technical Field

[0001] The utility model belongs to the technical field of HVAC pipelines, and in particular relates to a HVAC pipeline filtering and decontamination device. Background Art

[0002] HVAC ducts are mainly used in heating, ventilation and air conditioning systems in buildings to provide a comfortable indoor environment. The system transmits heat, cold air, air and water to different areas through a series of pipes, ducts and equipment to adjust indoor temperature, humidity and air quality.

[0003] Among them, HVAC pipe filtration and decontamination is one of the important links in the HVAC system. Its purpose is to maintain the normal operation of pipes and equipment, extend their life, and ensure the efficient operation of the system by filtering and removing solid particles, sediments, impurities and dirt in the pipes.

[0004] Common HVAC pipe filtering and decontamination devices usually have a filter screen at the joint of two HVAC pipes, so that the filter screen can filter impurities in the HVAC pipes, and the filtered impurities will be stored on the filter screen. When the device works for a long time, the filter screen stores too many impurities and needs to be cleaned. The staff needs to first loosen the bolts connecting the HVAC pipes to separate the two HVAC pipes, and then take out the filter screen to clean the impurities on the filter screen. When cleaning the filter screen, the HVAC device needs to stop working and wait until the filter screen is installed again before working. This method not only takes a long time to clean the filter screen, but also makes the device unable to work, affecting the working efficiency of the device. Utility Model Content

[0034] Cleaning kit includes:

[0035] Motor 7: The upper surface of the housing 1 is connected with the motor 7;

[0036] A screw rod 8 is longitudinally arranged in the housing 1, the screw rod 8 is fixedly connected to the output shaft of the motor 7, and the screw rod 8 is located at one end of the filter screen 4 close to the cover plate 2;

[0037] A slide rod 9, which is connected to the housing 1 and is symmetrically arranged with the screw rod 8;

[0038] The slider 10 is arranged on the screw rod 8, and the other end of the slider 10 is slidably connected to the slider 10;

[0039] Brush 11: A brush 11 is provided on one side of the slider 10 close to the filter screen 4, and the brush 11 fits the filter screen 4.

[0040] It can be seen from this embodiment that when working, the motor 7 is started, and the output shaft of the motor 7 is fixedly connected to the screw rod 8. The rotation of the output shaft of the motor 7 drives the screw rod 8 to rotate, so that the slider 10 can move up and down on the screw rod 8 and the slide rod 9. A brush 11 is provided on the side of the slider 10 close to the filter screen 4. The brush 11 is in contact with the filter screen 4. The up and down movement of the slider 10 drives the brush 11 to move up and down on the filter screen 4, so as to clean the impurities on the filter screen 4.

[0041] Embodiment 3:

[0042] This embodiment provides a HVAC pipeline filtering and decontamination device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0043] Also includes:

[0044] A mounting groove 12 is provided at the bottom of the inner surface of the housing 1;

[0045] A cleaning box 13 is provided on the mounting groove 12;

[0046] Cleaning box fixing assembly, the cleaning box 13 is connected to the mounting groove 12 through the cleaning box fixing assembly.

[0047] It can be seen from this embodiment that the cleaning box 13 is provided to collect impurities cleaned from the filter 4 by the brush 11. The cleaning box 13 is connected to the mounting groove 12 through a cleaning box fixing assembly, and is easy to install and disassemble, making it convenient to clean the cleaning box 13.

[0048] Embodiment 4:

[0049] This embodiment provides a HVAC pipeline filtering and decontamination device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0054] The other end of the limiting plate 16 is provided with a locking pin 17 , and the side of the locking pin 17 is arranged as an arc-shaped structure.

[0055] It can be seen from this embodiment that when in use, the cleaning box 13 is slid outward. At this time, since the side of the latch 17 is set to an arc structure, when the cleaning box 13 slides inside the installation groove 12, it will drive the latch 17 to be compressed and compress the first spring 15, thereby removing the cleaning box 13. When the cleaning box 13 is installed, when the cleaning box 13 is placed inside the installation groove 12, the latch 17 and the first spring 15 will be compressed again. When the latch 17 is aligned with the card hole 14, the first spring 15 rebounds, thereby driving the latch 17 to insert into the inside of the card hole 14 to achieve the installation and fixation of the cleaning box 13. The setting of the limit plate 16 can avoid the vertical part of the latch 17 from being inserted into the inside of the card hole 14, resulting in the problem that the cleaning box 13 cannot be removed later.
