Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, and in particular to an air source heat pump air inlet device with a dustproof structure. Background Technology

[0002] With increasing global attention to energy efficiency and environmental protection, air source heat pumps have been widely used as an efficient and environmentally friendly heating and cooling solution. However, in actual operation, air source heat pumps face the impact of environmental factors, especially the intrusion of particulate matter such as dust. Dust not only reduces heat exchange efficiency and leads to increased energy consumption, but also accelerates equipment wear, shortens service life, and may cause malfunctions.

[0003] Existing technologies typically employ simple metal mesh or inefficient filter materials as preliminary protective measures. While these traditional methods can block large particles from entering the system to some extent, their filtration effect on fine particles is limited and cannot meet the demands of high-precision air purification. Furthermore, traditional protective measures often neglect airflow resistance. High-efficiency filters can more effectively block dust and other particles, but they also increase airflow resistance, potentially reducing heat pump efficiency. Conversely, low-resistance filters, while helping to maintain good airflow, may not provide sufficient filtration. Therefore, it is necessary to address the shortcomings of existing technologies by designing an air source heat pump intake device with a dustproof structure. This device should feature a switchable dustproof structure, allowing for flexible adjustment of the emphasis on airflow and filtration, effectively balancing the airflow and filtration performance of the intake device. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an air source heat pump air inlet device with a dustproof structure.

[0005] The technical solution is as follows: An air source heat pump air intake device with a dustproof structure includes an air source heat pump outdoor unit, which serves as the assembly carrier for this device. The outdoor unit has an air vent inside its casing. The device also includes a mounting frame, a primary filter, electric push rods, connecting blocks, and a HEPA filter. The mounting frame is fixedly installed inside the air vent of the outdoor unit. The mounting frame is a frame with openings on both sides. A primary filter is installed at the opening of the mounting frame near the inner side of the outdoor unit. Two sets of electric push rods are symmetrically fixedly installed inside the mounting frame. Connecting blocks are fixedly installed at the push rod ends of the electric push rods. A HEPA filter is installed on the connecting blocks. The HEPA filter is located on the outer side of the mounting frame away from the outdoor unit. The electric push rods are used to drive the HEPA filter on the mounting frame.

[0006] As a further preferred embodiment, the mesh size of the HEPA filter is smaller than that of the primary filter. The primary filter acts as a pre-protective layer to prevent large particles from entering the more sophisticated filtration system, while the HEPA filter is used to filter out fine impurities, providing deeper and more efficient air purification.

[0007] As a further preferred embodiment, both the primary filter and the HEPA filter are detachably mounted on the mounting frame, allowing for convenient maintenance and replacement of the primary filter and the HEPA filter.

[0008] As a further preferred embodiment, the connecting block is provided with a snap-fit ​​component, and the HEPA filter is provided with an opening adapted to the snap-fit ​​component. The HEPA filter is detachably installed on the connecting block via the snap-fit ​​component.

[0009] As a further preferred embodiment, the fastener includes a wedge block, a guide rod, and a spring. The wedge block is slidably installed inside the connecting block, and the guide rod is fixedly connected to the connecting block. The wedge block and the guide rod are slidably adapted to each other. A spring is provided on the guide rod between the wedge block and the connecting block. The HEPA filter adapter fastener has a slot in its opening, and the slot is adapted to the corresponding wedge block on the same side.

[0010] As a further preferred embodiment, an air quality sensor is also included. The air quality sensor is installed on the outdoor unit of the air source heat pump. The air quality sensor has a built-in controller. The air quality sensor is activated and operated by the controller via an electric push rod. The air quality sensor is used to monitor the air quality outside the outdoor unit of the air source heat pump.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses only a primary filter for basic filtration when the outside air quality is good, maintaining a high air circulation efficiency; while when the air quality is poor, the HEPA filter is activated to provide deeper and more efficient air purification. This allows the device to adapt to changing environmental conditions without affecting performance, thus flexibly balancing the air circulation and filtration effects of the air source heat pump.

[0013] 2. The HEPA filter of this utility model can be quickly installed and disassembled through snap fasteners, which not only ensures the stability of the filter, but also improves the convenience of assembly and disassembly, making it suitable for frequent operation.

[0014] 3. This utility model can also monitor the outside air quality in real time through an air quality sensor, and automatically control the electric push rod according to the air quality, so that the HEPA filter can be activated or deactivated when needed, and the HEPA filter can be flexibly switched on the mounting frame.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0022] An air-source heat pump air intake device with a dustproof structure, such as Figures 1-5As shown, the device includes an air source heat pump outdoor unit 1, which serves as the assembly carrier for this device. The outdoor unit 1 has an air vent inside its casing. It also includes a mounting frame 2, a primary filter 3, electric actuators 4, connecting blocks 5, and a HEPA filter 6. The mounting frame 2 is fixedly installed inside the air vent of the outdoor unit 1. The mounting frame 2 is a frame with openings on both sides. The primary filter 3 is installed near the opening on the inner side of the mounting frame 2. Two sets of electric actuators 4 are symmetrically fixedly installed inside the mounting frame 2. Connecting blocks 5 are fixedly installed at the ends of the actuators 4. Connecting blocks 5 are mounted on the connecting blocks 5. There is a HEPA filter 6, which is located on the outside of the mounting frame 2 away from the air source heat pump outdoor unit 1. The electric push rod 4 is used to drive the HEPA filter 6 on the mounting frame 2, so that the HEPA filter 6 can be selected to be activated or deactivated on the mounting frame 2. When the outside air quality is poor, the HEPA filter 6 is attached to the mounting frame 2 and activated, so that the air intake device can effectively filter. When the outside air quality is good, the HEPA filter 6 is separated from the mounting frame 2 and does not work. At this time, the primary filter 3 filters and improves the air circulation effect. Thus, the air circulation and filtration effect can be flexibly switched and balanced.

[0023] like Figures 1-3 As shown, the mesh size of HEPA filter 6 is smaller than that of primary filter 3. Primary filter 3 acts as a pre-protective layer to prevent large particles from entering the more precise filtration system. HEPA filter 6 is used to filter fine impurities, providing deeper and more efficient air purification. Both primary filter 3 and HEPA filter 6 are detachable and installed on mounting frame 2, which allows for convenient maintenance and replacement of primary filter 3 and HEPA filter 6.

[0024] like Figure 4 and Figure 5 As shown, the connecting block 5 is provided with a snap fastener, and the HEPA filter 6 is provided with an opening for adapting the snap fastener. The HEPA filter 6 is detachably installed on the connecting block 5 through the snap fastener. The snap fastener includes a wedge block 7, a guide rod 8 and a spring 9. The wedge block 7 is slidably installed inside the connecting block 5, and the guide rod 8 is fixedly connected to the connecting block 5. The wedge block 7 and the guide rod 8 are slidably adapted. A spring 9 is provided on the guide rod 8 between the wedge block 7 and the connecting block 5. The opening of the HEPA filter 6 adapted to the snap fastener is provided with a slot 10, and the slot 10 is adapted to the corresponding wedge block 7 on the same side.

[0025] like Figure 1As shown, it also includes an air quality sensor 11. An air quality sensor 11 is installed on the outdoor unit 1 of the air source heat pump. The air quality sensor 11 has a built-in controller. The air quality sensor 11 controls the electric push rod 4 to be activated and operated through the controller. The air quality sensor 11 is used to monitor the air quality outside the outdoor unit 1 of the air source heat pump. When the air quality sensor 11 senses that the external air quality is poor, it controls the push rod of the electric push rod 4 to retract, so that the HEPA filter 6 covers the mounting frame 2 for filtration, maintaining the effectiveness of filtration. When the air quality sensor 11 senses that the external air quality is good, it controls the push rod of the electric push rod 4 to extend, so that the HEPA filter 6 is away from the mounting frame 2 and does not function. Only the primary filter 3 is used for necessary filtration, maintaining good air circulation for the air source heat pump.

[0026] When the outside air quality is good, the primary filter 3 alone is sufficient to meet basic filtration needs and ensure adequate airflow for the effective operation of the heat pump. However, when the air quality sensor 11 detects a decline in outside air quality, indicating a higher concentration of fine particulate matter, the built-in controller responds based on the sensor data. The controller then instructs the electric push rod 4 to retract, causing the connecting block 5 to move inward. The HEPA filter 6 on the connecting block 5 then adheres to the mounting frame 2, forming a second, more refined filtration barrier. Because the HEPA filter 6 has smaller pores, it can efficiently capture tiny dust particles, pollen, bacteria, and other pollutants, providing a higher level of air purification. Conversely, if... If the air quality sensor 11 detects that the outside air quality has recovered or was already in a good state, the controller will instruct the electric push rod 4 to push out, allowing the HEPA filter 6 to separate from the mounting frame 2 and no longer participate in the air filtration process. This reduces the airflow resistance of the entire air intake device, improves the heat pump efficiency, and extends the service life of the HEPA filter 6. When it is necessary to remove the HEPA filter 6, the user can slightly press the wedge block 7 to overcome the force of the spring 9, causing the wedge block 7 to retract into the guide rod 8, thereby releasing the locking state with the slot 10. The HEPA filter 6 can then be easily removed from the connecting block 5, making it convenient for the user to clean or replace the filter. It also allows direct cleaning of the primary filter 3 inside the mounting frame 2.

[0027] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
