Description

Technical Field

[0001] This utility model relates to the field of dust removal device technology, and in particular to a dust removal device for energy-saving central air conditioning. Background Technology

[0002] During long-term operation, central air conditioning systems are prone to accumulating dust, impurities, and dirt. These substances can obstruct airflow, increase the system load, and cause the air conditioner to consume more energy to maintain the same cooling or heating effect. However, by installing a dust removal device, the internal pipes, filters, and fans of the air conditioner can be cleaned, ensuring smooth airflow, improving the system's cooling or heating efficiency, and reducing energy consumption.

[0003] Central air conditioning systems are typically equipped with high-efficiency filters, such as HEPA filters or electrostatic filters, which can effectively intercept dust, bacteria and other fine particles in the air. These filters achieve a dust removal effect, allowing the air conditioning system to keep the indoor air clean.

[0004] Considering that dust easily accumulates on the filter screen during long-term use, affecting air circulation and filtration efficiency of the air conditioner, it is necessary to replace it. Usually, when replacing it, the filter screen is first loosened and then pulled out directly. However, the filter screen usually accumulates a lot of dust, and when the filter screen is pulled out directly, the dust and pollutants on its surface can easily spread into the air. This not only pollutes the surrounding environment but may also re-enter the air conditioning system, causing secondary pollution and affecting the overall efficiency of the air conditioner. Therefore, a dust removal device for energy-saving central air conditioning is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dust removal device for energy-saving central air conditioning systems. It aims to improve the existing technology where filters, used for extended periods, easily accumulate dust, affecting airflow and filtration efficiency, and requiring regular replacement. Typically, replacement involves loosening the filter and pulling it out directly; however, the dust and pollutants accumulated on the filter can easily spread during this process, polluting the surrounding environment and potentially re-entering the air conditioning system, causing secondary pollution and affecting air conditioning efficiency.

The outer surface of the wedge block is elastically connected to the inner surface of the handle through the spring B. The right side of the outer surface of the wedge block is engaged with the outer surface of the hinge.

[0009] As a further description of the above technical solution:

[0010] A filter screen is inserted into the inner surface of the plate. A baffle is slidably connected to the left side of the inner surface of the plate. The right side of the outer surface of the baffle is in contact with the left side of the outer surface of the filter screen. An anti-slip groove is provided on the top of the outer surface of the baffle.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a dust removal device for an energy-saving central air conditioning system, comprising a pipe 1, a plate 5 inserted into the inner surface of the pipe 1, allowing the plate 5 to move vertically along the inner surface of the pipe 1, a baffle 6 hinged to the top of the outer surface of the plate 5, allowing the baffle 6 to flip along the top of the outer surface of the plate 5, a hinge rod 3 hinged to the outer surface of the baffle 6, allowing the hinge rod 3 to flip the baffle 6 when it moves, and a hinge member 4 hinged to the top of the outer surface of the hinge rod 3, allowing the hinge member 4 to drive the hinge rod when it moves vertically. 3. The plate body 5 has a handle 2 fixedly connected to the top of its outer surface, which provides a fixed support for the handle 2. The outer surface of the hinge 4 is slidably connected to the inner surface of the handle 2, allowing the hinge 4 to move vertically along the inner surface of the handle 2. The outer surface of the hinge 4 is fixedly connected to a column 15, which can drive the two sets of hinges 4 to move vertically together when the column 15 moves vertically. The inner surface of the handle 2 is provided with a positioning component, which can fix the hinge 4 in a designated position.

[0034] Reference Figure 3 , Figure 6 The positioning component includes a toggle block 10, a wedge block 14, and a spring B12. The outer surface of the toggle block 10 is slidably connected to the middle of the inner surface of the handle 2, allowing the toggle block 10 to move laterally along the inner surface of the handle 2. The right side of the outer surface of the toggle block 10 is fixedly connected to the left side of the outer surface of the wedge block 14, allowing the toggle block 10 to move laterally and simultaneously move the wedge block 14. The outer surface of the wedge block 14 is elastically connected to the inner surface of the handle 2 through the spring B12, allowing the wedge block 14 to always move inward without being affected by external force. The right side of the outer surface of the wedge block 14 is engaged with the outer surface of the hinge 4, allowing the hinge 4 to be fixed in a designated position by engaging with the outer surface of the wedge block 14.

[0035] Reference Figures 3-5A filter screen 7 is inserted into the inner surface of the plate 5, so that the filter screen 7 can move together when the plate 5 moves. A cover plate 8 is slidably connected to the left side of the inner surface of the plate 5, so that the cover plate 8 can move vertically along the left side of the inner surface of the plate 5. The right side of the outer surface of the cover plate 8 contacts the left side of the outer surface of the filter screen 7, so that the filter screen 7 inside the plate 5 can be prevented from sliding out when the cover plate 8 is inserted into the plate 5. An anti-slip groove is provided on the top of the outer surface of the cover plate 8, so that the cover plate 8 can be pulled out with less effort. The top of the inner surface of the cover plate 8 is elastically connected to a snap-fit ​​member 9 by a spring A11, so that the snap-fit ​​member 9 can always move inward without the influence of external force. The right side of the outer surface of the snap-fit ​​member 9 is inserted into the top of the inner surface of the plate 5, so that the cover plate 8 can be fixed to the left side of the inner surface of the plate 5 when the snap-fit ​​member 9 is inserted into the top of the inner surface of the plate 5.

[0036] Reference Figures 4-6 One end of spring B12 is fixedly connected to the inner surface of handle 2, and the other end of spring B12 is fixedly connected to the left side of the outer surface of inclined block 14, so that when the toggle block 10 is stopped, inclined block 14 can move outward and extend into handle 2 under the elastic force of spring B12. One end of spring A11 is fixedly connected to the top of the inner surface of cover plate 8, and the other end of spring A11 is fixedly connected to the outer surface of latching member 9, so that when the latching member 9 is stopped, latching member 9 can always move to the right under the elastic force of spring A11.

[0037] Reference Figures 1-3 Both the hinge rod 3 and the hinge member 4 are provided in two sets, so that the hinge member 4 can achieve a more stable effect when the baffle 6 is rotated by the hinge rod 3. The top of the inner surface of the pipe 1 is fixedly connected to the positioning block 13, which provides a fixed support effect for the positioning block 13 through the top of the inner surface of the pipe 1. The top of the outer surface of the positioning block 13 is in contact with the top of the outer surface of the plate 5, so that when the plate 5 is inserted into the pipe 1, it can achieve the effect of positioning and insertion under the action of the positioning block 13. The top of the outer surface of the plate 5 is fixedly connected to the fixing member 16, so that after the plate 5 is inserted into the pipe 1, the plate 5 can be fixed inside the pipe 1 by using bolts through the fixing member 16.

[0038] Working principle: When replacing the filter screen 7, first move the toggle block 10 outward to move the inclined block 14 inward, thereby releasing the fixing effect on the hinge 4. Then, as the hinge 4 loses its fixing effect, the baffle 6 will flip downward along the top of the plate 5 due to gravity, blocking both ends of the filter screen 7 to prevent dust on the filter screen 7 from falling to other areas when the plate 5 is pulled out. Then, unscrew the bolts on the fixing part 16 to release the fixing connection between the plate 5 and the pipe 1. Then, hold the handle 2 and pull the plate 5 out of the pipe 1.

[0039] When moving plate 5 to the cleaning area, first push the latch 9 on the cover 8 outward to stop it from being inserted into plate 5. Then pull the cover 8 upward to expose the side of the filter screen 7. Then, hold the handle 2 on the side of the filter screen 7 and pull the filter screen 7 out of the plate 5. Clean plate 5 and baffle 6 first, then insert the new filter screen 7 into the plate 5. Then insert the cover 8 into the side of plate 5. While inserting, push the latch 9 outward. After the cover 8 is inserted in place, release the latch 9, allowing the latch 9 to engage with plate 5 under the action of spring A11, thus fixing the cover 8 to the left side of the inner surface of plate 5. Then, hold the handle 2 and insert plate 5 into pipe 1. After entering the interior, pull the column 15 upward, causing it to simultaneously move the two sets of hinges 4 upward. The two sets of hinges 4, through the four sets of hinge rods 3, cause the baffles 6 on both sides of the plate 5 to flip upward, exposing the filter screen 7 inside the pipe 1. When the hinge 4 moves upward to the designated position, it will press the inclined block 14 into the handle 2 by squeezing the inclined surface of the inclined block 14. When the hinge 4 moves to the appropriate position, the inclined block 14 will stop being squeezed and, under the elastic force of the spring B12, engage with the outer surface of the hinge 4, fixing the hinge 4 in the designated position. At the same time, the two sets of baffles 6 are always in the upward open state. Finally, the plate 5 is fixed inside the pipe 1 by bolts through the fixing member 16.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
