Description

Technical Field

[0001] This utility model belongs to the technical field of air conditioning filter elements, and particularly relates to an air conditioning filter element with adjustable airflow. Background Technology

[0002] In modern life, air conditioners are widely used in various places, such as homes, cars, and offices. As a crucial component of the air conditioning system, the air conditioner filter plays a vital role. It is primarily used to filter the air entering the air conditioning system, removing dust, pollen, impurities, etc., thus ensuring that the air blown out by the air conditioner is fresh and clean, providing people with a healthy and comfortable air environment. Whether in areas with severe smog or in places with high air quality requirements, such as hospitals and laboratories, air conditioner filters are indispensable.

[0003] Most existing air conditioning filters use a simple filter structure to achieve air filtration. While this structure can effectively intercept some impurities in the air, its function is limited to air filtration. Lacking adjustment mechanisms, it's difficult to control the airflow rate. In actual use, different environments and needs place different demands on the filtration rate of air conditioners. In conditions of good air quality, an excessively high filtration rate may increase energy consumption. Existing air conditioning filters cannot adjust their filtration rate according to usage conditions, making it difficult to meet diverse needs. Utility Model Content

[0004] The purpose of this invention is to provide an air conditioning filter element with adjustable airflow, aiming to improve the technical problem in the prior art where the lack of a device for adjusting airflow makes it difficult to adjust airflow during use.

[0005] To achieve the above objectives, the adjustable airflow air conditioning filter element provided in this embodiment of the utility model includes a housing, a sealing cover fixedly connected to one side of the housing, an outer shell fixedly connected to one side of the sealing cover, a rotating rod rotatably connected to the inner wall of the outer shell, a guide plate fixedly connected to one end of the rotating rod away from the outer shell, a connecting rope slidably connected to the outer wall of the rotating rod, an outer shell two fixedly connected to one end of the connecting rope, a positioning block rotatably connected inside the outer shell two, a reset assembly provided inside the outer shell two, a positioning groove opened inside the outer shell one, and the movable end of the positioning block slidably connected to the inner wall of the outer shell one.

[0006] Optionally, the reset assembly includes a spring, the outer wall of which is disposed inside the housing, and both ends of the spring are fixedly connected to the inner wall of the positioning block.

[0007] Optionally, a reinforcing layer is fixedly connected to the inner wall of the shell, a buffer layer is fixedly connected to the side of the reinforcing layer away from the shell, and a waterproof layer is fixedly connected to the side of the buffer layer away from the reinforcing layer.

[0008] Optionally, an activated carbon plate is fixedly connected inside the shell, and an incense burner is fixedly connected to the side of the activated carbon plate away from the shell.

[0009] Optionally, a second sealing cover is fixedly connected to the other side of the housing, and the outer wall of the reinforcing layer is fixedly connected to the inner wall of the second sealing cover.

[0010] Optionally, a connecting block is fixedly connected to the side of the second outer shell away from the first outer shell, and a pressing plate is fixedly connected to the side of the connecting block away from the first outer shell.

[0011] Optionally, a rubber ring is fixedly connected to the inner wall of the housing.

[0012] Optionally, a filter screen is fixedly connected to the inner wall of the housing.

[0013] The adjustable airflow air conditioning filter element provided in this embodiment of the utility model has at least one of the following technical effects:

[0014] 1. In this invention, the airflow through the filter can be precisely controlled by adjusting the opening and closing degree of the guide plate. In actual use scenarios, different environments have significantly different requirements for air conditioning airflow and filtration rate. For example, when dust is heavy, the opening degree of the guide plate can be increased to accelerate airflow, improve filtration efficiency, and quickly purify the air; when the air quality is good, the opening degree of the guide plate can be reduced to decrease the airflow speed and reduce air conditioning energy consumption. This flexible adjustment function allows the air conditioning filter element to adapt to various environments, greatly enhancing the versatility of the equipment and meeting the diverse needs of users.

[0015] 2. In this utility model, the filter element is internally configured with multiple layers for different effects. The combination of a reinforcing layer, a buffer layer, and a waterproof layer enhances the structural strength of the filter element, extends its service life, effectively buffers external impacts, prevents moisture erosion, and ensures the normal operation of the filter element. The activated carbon plate installed behind the filter screen can adsorb harmful gases and odors in the air, further purifying the air; the aromatherapy plate allows the purified air to emit a pleasant fragrance, improving indoor air quality and atmosphere, and creating a more comfortable environment for users. In addition, the design of separating the filter screen and the activated carbon plate prevents the entire filter element from being affected due to damage to one component.

[0029] Reference Figure 1 - Figure 4This utility model provides an embodiment of an air conditioning filter element with adjustable airflow, comprising a housing 1, a sealing cover 14 fixedly connected to one side of the housing 1, the sealing cover 14 protecting the internal interlayer of the housing 1, an outer shell 2 fixedly connected to one side of the sealing cover 14, a rotating rod 3 rotatably connected to the inner wall of the outer shell 2, a guide plate 4 fixedly connected to the end of the rotating rod 3 away from the outer shell 2, a connecting rope 5 slidably connected to the outer wall of the rotating rod 3, the connecting rope 5 having a connecting rod and the interior of the rotating rod 3, the rotating rod 3 rotating when the connecting rope 5 moves, thereby rotating the guide plate 4 and adjusting the airflow, one end of the connecting rope 5 fixedly connected to an outer shell 2 8, the connection between the connecting rope 5 and the outer shell 2 8 allowing the rotating rod 3 to rotate when the outer shell 2 8 moves, a positioning block 9 rotatably connected inside the outer shell 2 8, a reset component inside the outer shell 2 8, and a positioning groove 1 inside the outer shell 2 8. 1. The movable end of the positioning block 9 is slidably connected to the inner wall of the outer shell 2. When the positioning block 9 slides on the inner wall of the outer shell 2, it can be locked in the positioning groove 11 at different positions to achieve a precise positioning effect. The reset component includes a spring 10. The outer wall of the spring 10 is set inside the outer shell 8. Both ends of the spring 10 are fixedly connected to the inner wall of the positioning block 9. When the outer shell 8 moves, the positioning block 9 can be squeezed back into the inner shell 8 by the inner wall of the outer shell 2. When the movable end of the positioning block 9 coincides with the positioning groove 11, the positioning block 9 is locked in the positioning groove 11 to achieve precise positioning. A connecting block 6 is fixedly connected to the side of the outer shell 8 away from the outer shell 2. A pressing plate 7 is fixedly connected to the side of the connecting block 6 away from the outer shell 2. By pressing or pulling the pressing plate 7, the position of the outer shell 8 can be moved. A rubber ring 17 is fixedly connected to the inner wall of the shell 1. The rubber ring 17 can isolate external impurities and prevent them from entering the interlayer inside the shell 1, which would affect the service life of the device.

[0030] Specifically, a sealing cover 14 is fixedly connected to one side of the housing 1. The main function of the sealing cover 14 is to protect the various internal layers of the housing 1. An outer shell 2 is fixedly connected to one side of the sealing cover 14. The outer shell 2 ensures that the rotating rod 3 can rotate smoothly on its inner wall, ensuring the stability and reliability of the entire airflow regulating structure. The rotating rod 3 is rotatably connected to the inner wall of the outer shell 2. A guide plate 4 is fixedly connected to the end of the rotating rod 3 away from the outer shell 2. When the rotating rod 3 rotates, the guide plate 4 will rotate accordingly, thereby changing the direction and speed of the airflow. The power source for its rotation is the connection... Rope 5 is slidably connected to the outer wall of the rotating rod 3. A connecting rod is provided on the outer wall of the connecting rope 5 and connects to the inside of the rotating rod 3. This connection method allows the connecting rope 5 to drive the rotating rod 3 to rotate when it moves. In different usage environments, the opening of the guide plate 4 can be flexibly adjusted by controlling the rotation angle of the rotating rod 3 to meet different airflow filtration requirements. One end of the connecting rope 5 is fixedly connected to the outer casing 8. Through the connection between the connecting rope 5 and the outer casing 8, the movement of the outer casing 8 can drive the connecting rope 5 to move, thereby driving the rotating rod 3 to rotate. The outer casing 2 has a rotatable positioning block 9 inside. The positioning block 9 cooperates with the positioning groove 11 opened in the inner wall of the outer casing 1, which plays a role in precise positioning. The outer casing 2 has a reset assembly inside, which includes a spring 10. The outer wall of the spring 10 is set inside the outer casing 2, and both ends of the spring 10 are fixedly connected to the inner wall of the positioning block 9. When the outer casing 2 moves, the positioning block 9 will be squeezed by the inner wall of the outer casing 1, thereby compressing the spring 10 and retracting it into the outer casing 2. When the movable end of the positioning block 9 coincides with the positioning groove 11, the spring 10 will retract into the outer casing 2 due to its elastic force. The positioning block 9 will be locked in the positioning groove 11 to achieve precise positioning. The outer shell 2 8 is fixedly connected to the side away from the outer shell 1 2. The connecting block 6 is fixedly connected to the side away from the outer shell 1 2. The connecting block 6 connects the outer shell 2 8 and the pressing plate 7 together, so that the force applied by the pressing plate 7 can be smoothly transmitted to the outer shell 2 8, thereby controlling the position of the outer shell 2 8. The inner wall of the shell 1 is fixedly connected to the rubber ring 17. The rubber ring 17 has good sealing performance and can effectively isolate external impurities and prevent these impurities from entering the interlayer inside the shell 1.

[0031] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5A reinforcing layer 20 is fixedly connected to the inner wall of the housing 1. The reinforcing layer 20 strengthens the air conditioning filter element and increases its lifespan. A buffer layer 12 is fixedly connected to the side of the reinforcing layer 20 away from the housing 1. The buffer layer 12 disperses the force of the air conditioner or external forces, ensuring the stability of the air conditioning filter element. A waterproof layer 13 is fixedly connected to the side of the buffer layer 12 away from the reinforcing layer 20. The waterproof layer 13 works in conjunction with the rubber ring 17 to isolate moisture and prevent it from corroding the internal layers of the housing 1. An activated carbon plate 19 is fixedly connected inside the housing 1. By separating the activated carbon plate 19 from the filter screen 18, the problem of "damage to one leads to damage to all" can be prevented. An aromatherapy plate 16 is fixedly connected to the side of the activated carbon plate 19 away from the outer shell 2. The aromatherapy plate 16 provides a pleasant fragrance to the purified air. A sealing cover 2 15 is fixedly connected to the other side of the housing 1. The outer wall of the reinforcing layer 20 is fixedly connected to the inner wall of the sealing cover 2 15. A filter screen 18 is fixedly connected to the inner wall of the housing 1, which provides a preliminary filtration effect.

[0032] Specifically, a reinforcing layer 20 is fixedly connected to the inner wall of the housing 1. The reinforcing layer 20 effectively enhances the overall structural strength of the filter element, preventing it from easily deforming or cracking when subjected to external forces. A buffer layer 12 is fixedly connected to the side of the reinforcing layer 20 away from the housing 1. Air conditioners generate vibrations during operation, and the filter element may also be subjected to external impacts during transportation and installation. The buffer layer 12 effectively disperses these forces from the air conditioner or external sources. By dispersing vibrations and impacts, the buffer layer 12 ensures the stability of the internal structure of the air conditioning filter element. A waterproof layer 13 is fixedly connected to the side of the buffer layer 12 away from the reinforcing layer 20. In humid environments, moisture in the air can easily enter the air conditioning system. The waterproof layer 13 works in conjunction with the rubber ring 17 fixedly connected to the inner wall of the housing 1 to isolate moisture, increasing the service life of the air conditioning filter element. An activated carbon plate 19 is fixedly connected inside the housing 1. The activated carbon plate 19 has a rich porous structure and can utilize adsorption principles to remove harmful substances. Gases and odors are firmly adsorbed on its surface, further purifying the air, improving air quality, and providing users with a healthier breathing environment. Furthermore, by separating the activated carbon plate 19 from the filter screen 18, the activated carbon plate 19 can still function normally even when the filter screen 18 is clogged or damaged by impurities due to long-term use, avoiding a "one-to-all" problem and improving the reliability and practicality of the entire filter element. An aromatherapy plate 16 is fixedly connected to the side of the activated carbon plate 19 away from the outer shell 1. The aromatherapy plate 16 can slowly release a pleasant fragrance, adding a fresh and pleasant scent to the purified air, effectively improving indoor air quality and atmosphere. A sealing cover 2 15 is fixedly connected to the other side of the shell 1. The sealing cover 2 15 works together with the sealing cover 14 to completely seal all the internal layers of the shell 1, providing comprehensive protection for the internal layers. A filter screen 18 is fixedly connected to the inner wall of the shell 1. When air enters the filter element, the filter screen 18 can intercept larger particles of impurities in the air, such as dust, hair, and pollen, achieving a preliminary filtration effect.

[0033] Working principle: When airflow needs to be adjusted, the user can press or pull the press plate 7 to move the connected block 6. The connection between the connecting block 6 and the outer casing 8 allows the outer casing 8 to move together. When the outer casing 8 moves, the connecting rope 5 also moves. Since the connecting rod on the outer wall of the connecting rope 5 is connected to the inside of the rotating rod 3, the movement of the connecting rope 5 will cause the rotating rod 3 to rotate. When the rotating rod 3 rotates, the guide plate 4 fixed at one end will also rotate, thereby changing the opening of the guide plate 4 and adjusting the airflow rate and direction. When the outer casing 8 moves, the positioning block 9, when squeezed by the inner wall of the outer casing 2, will compress the spring 10 inside the outer casing 2 and retract it into the inner casing 8. When the movable end of the positioning block 9 coincides with the positioning groove 11 on the inner wall of the outer casing 2, the elasticity of the spring 10 makes the positioning block 9 lock in the positioning groove 11, ensuring that the guide plate 4 is stable at the required adjustment angle, precisely controlling the airflow. The air first passes through the filter screen 18, which can intercept larger particles of impurities in the air, such as dust. Dust, hair, pollen, etc., are initially filtered. The air after initial filtration then enters the activated carbon plate 19. The activated carbon plate 19 uses its rich porous structure to adsorb harmful gases and odors in the air through the principle of adsorption, further purifying the air. The air purified by the activated carbon plate 19 then passes through the fragrance plate 16. The fragrance plate 16 can carry out its fragrance, adding fragrance to the purified air and improving indoor air quality and atmosphere. The reinforcing layer 20 fixedly connected to the inner wall of the shell 1 enhances the overall structural strength of the filter element, making it less prone to deformation and breakage when subjected to external forces. The buffer layer 12 on the outside of the reinforcing layer 20 can disperse the vibration generated by the operation of the air conditioner and the impact force brought by external collisions, ensuring the stability of the internal structure of the filter element. The waterproof layer 13 on the outside of the buffer layer 12 cooperates with the rubber ring 17 on the inner wall of the shell 1 to isolate moisture from the outside and extend the service life of the filter element. The sealing cover one 14 and sealing cover two 15 are fixed on both sides of the shell 1, sealing the internal interlayer and protecting the internal components from external impurities.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
