[0002] In the living rooms of modern, compact homes, a furniture-style air purifier that also functions as a minimalist bookshelf becomes a central piece of furniture. Its main structure is a tiered bookshelf, capable of storing books and decorative items, while integrating custom-designed indoor air purification components. This allows for silent air purification in a coexisting environment where family members can relax and read, and children can play. It doesn't take up extra space, yet meets daily storage and air purification needs, creating an indoor environment that is both practical and healthy. "Coexisting with humans" means the device operates without noise pollution or safety hazards, allowing for close and prolonged contact with people. "Custom-designed indoor air purifier" refers to purification modules tailored to the size and style of furniture, achieving a deep integration of purification function and furniture form. "Furniture-style air purifier" integrates air purification functionality with the furniture structure, making the device both a practical piece of furniture and an air purification tool.

[0003] The working principle of most existing air purification equipment is to draw indoor air into the equipment through a fan. When the air flows through the filter, the filter intercepts pollutants such as dust, formaldehyde, and odors. The purified air is then discharged through the air outlet, forming an indoor air circulation and gradually improving indoor air quality. Some equipment will also be equipped with modules such as ultraviolet sterilization and negative ion generation to further enhance the purification effect.

[0004] In existing technologies, some air purification devices use electrically driven components to adjust the size of the air vents, which increases the complexity of the internal structure of the device, leading to increased assembly difficulty. It also requires additional investment in the purchase of precision parts and drive components, which significantly increases the overall production cost of the device and is not conducive to the widespread application of the device. Therefore, a furniture-type air purification device with adjustable air vents is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a furniture-type air purification device with adjustable air vents, aiming to improve the problems of complex air vent adjustment structures and high costs in some existing air purification devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A furniture-type air purifier with adjustable air vents includes a housing, an adjustment mechanism inside the housing, a purification mechanism on the top outer side of the housing, a support column fixedly connected inside the purification mechanism, multiple support columns fixedly connected inside the housing, the adjustment mechanism including a fixed column, the fixed column being fixedly connected to the outside of the housing, multiple baffles rotatably connected to the outside of the fixed column, a gear fixedly connected to one side of the outer side of the baffles, a slide bar slidably connected to the outside of the fixed column, a slide column fixedly connected to the outside of the slide bar, and an adjustment and protection assembly on the bottom outer side of the housing. As a further description of the above technical solution: The purification mechanism includes a slot, which is formed on the top of the outer shell.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the sliding column drives the sliding strip to slide, thereby pushing the sliding column to slide in the limiting groove of the outer shell, causing the sliding strip to move. Its rack meshes with the gear of the baffle, driving the gear to rotate, and then causing the baffle to rotate around the fixed column, realizing the adjustment of the size and angle of the air outlet. When adjusting the number of air outlets or when idle, the sliding ring is pushed and slides along the outer shell under the action of the friction of the reinforcing strip. The number of air outlets is adjusted with the help of the built-in windproof cloth. When idle, the reinforcing strip is slid to the top to prevent dust. The operation is simple and the dustproof performance is good, which improves the durability of the equipment.

[0008] 2. In this utility model, the airflow is circulated by a fan: the operation of the fan generates negative pressure, which draws air in from the bottom of the shell, and the air passes through the medium-density polyester fiber layer of the filter to intercept pollen and other impurities, the folded HEPA glass fiber layer to capture tiny particles, the activated carbon layer to adsorb gaseous pollutants, and finally the clean air is discharged from the top through the air guide plate, realizing a multi-layer purification function.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0012] Example: A furniture-style air purifier with adjustable air vents, referring to Figure 1 , Figure 4 and Figure 5 The system includes an outer shell 1, with an adjustment mechanism 2 inside the shell 1. The adjustment mechanism 2 is used to adjust the size, angle, and number of air outlets to meet the air outlet requirements in different scenarios. A purification mechanism 3 is set on the top outer side of the shell 1. A support column 5 is fixedly connected inside the purification mechanism 3. The purification mechanism 3 is responsible for completing the entire process of air intake, filtration and purification, and clean air exhaust. Multiple support columns 5 are fixedly connected inside the shell 1. The support columns 5 cooperate with the internal support columns 5 of the shell 1 to provide vertical support and positioning for the filter 39, preventing the filter 39 from shifting under the impact of airflow. The shell 1 provides installation support for the internal adjustment mechanism 2 and the external purification mechanism 3. At the same time, the closed structure forms an air circulation cavity to ensure the orderly flow of purified airflow. Specifically, when the equipment is working, the fan 4 of the purification mechanism 3 is started to generate negative pressure. Air is drawn in from the bottom of the outer casing 1 and filtered through multiple layers of filter screen 39 positioned by the support column 5. The purified air is discharged from the top under the guidance of the air guide plate 34. When the air outlet needs to be adjusted, the sliding column 25 of the adjustment mechanism 2 drives the sliding strip 24 to slide. Its rack and pinion mesh with the gear 23 of the baffle 22, causing the baffle 22 to rotate around the fixed column 21, changing the size and angle of the air outlet. When idle or when the number of air outlets needs to be controlled, the reinforcing strip 264 of the sliding adjustment protective component 26 is slid to drive the protective sleeve 262 to unfold the windproof cloth to adjust the air outlet. At the same time, it can slide to the top to prevent dust.

[0013] The adjusting mechanism 2 includes a fixed column 21, which is fixedly connected to the outside of the outer casing 1. Multiple baffles 22 are rotatably connected to the outside of the fixed column 21, providing stable support for the baffles 22. A gear 23 is fixedly connected to one side of the outer surface of each baffle 22, converting the linear motion of the slide bar 24 into the rotational motion of the baffle 22. The baffle 22 changes the opening degree and airflow direction of the air outlet by blocking or unfolding, and is the direct actuator for adjusting the air outlet. A slide bar 24 is slidably connected to the outside of the fixed column 21. The unit is fixedly connected to a sliding column 25. An adjustment and protection component 26 is provided on the bottom outer side of the housing 1. A rack is provided on the outer side of the slide bar 24. The slide bar 24 drives the gear 23 to rotate by sliding linearly. It is the intermediate component for power transmission of the adjustment mechanism 2. The outer side of the rack and the outer side of the gear 23 are meshed and connected. Multiple limiting grooves are provided inside the housing 1. The inside of the limiting grooves is slidably connected to the outside of the sliding column 25. The sliding column 25 is a component for manual operation by the user. By pushing the sliding column 25, the slide bar 24 is moved to slide, thereby triggering the adjustment action. Specifically, when the user needs to adjust the air vent, they can manually push the sliding column 25. As the sliding column 25 slides in the limiting groove inside the housing 1, it drives the sliding strip 24 to slide in a straight line. The rack on the outside of the sliding strip 24 is tightly meshed with the gear 23. As the sliding strip 24 moves, the rack drives the gear 23 to rotate. The gear 23 is fixed on the outside of the baffle 22. Its rotation drives the baffle 22 to rotate around the fixed column 21, thereby changing the size of the air vent. For example, the air vent area can be increased or decreased, and the air vent direction can be adjusted, such as making the air blow upward, downward, or to the side. The adjustment of the protective component 26 can meet the corresponding needs through operation when the equipment is not in use or when the number of air vents needs to be adjusted.

[0014] The adjustable protective component 26 includes a fixing ring 261, which is externally fixedly connected to the bottom outer side of the housing 1. A protective sleeve 262 is provided inside the fixing ring 261. The fixing ring 261 provides an installation base for the protective sleeve 262 and defines the initial position of the protective sleeve 262. A sliding ring 263 is fixedly connected to one end of the protective sleeve 262. The protective sleeve 262 has a built-in extendable windproof cloth, which can change the coverage of the air inlet by extending or retracting, thereby adjusting the number of air inlets and preventing dust. Two reinforcing strips 264 are externally fixedly connected to the sliding ring 263. The movement of the sliding ring 263 drives the protective sleeve 262 to extend or retract, which is the motion transmission component of the protective component. The reinforcing strips 264 are externally slidably connected to the outside of the housing 1. The reinforcing strips 264 enhance the connection stability between the sliding ring 263 and the housing 1, and at the same time, achieve sliding positioning through friction with the housing 1 to prevent the sliding ring 263 from shifting on its own. Specifically, when adjusting the protective component 26, the fixing ring 261 first provides an installation base for the protective sleeve 262 and defines its initial position. When it is necessary to adjust the number of air vents or to prevent dust, the sliding ring 263, which is fixed to one end of the protective sleeve 262, is manually pushed. The sliding ring 263 drives the reinforcing strip 264 to slide along the outside of the outer shell 1. The reinforcing strip 264 not only enhances the connection stability between the sliding ring 263 and the outer shell 1, but also achieves sliding positioning through friction to prevent it from shifting on its own. At the same time, the movement of the sliding ring 263 causes the protective sleeve 262 to extend or retract, and the windproof cloth inside changes the coverage of the air inlet accordingly, ultimately achieving the adjustment of the number of air vents. When idle, it can also play a role in preventing dust when fully extended.

[0015] Reference Figure 2 , Figure 3 and Figure 6 The purification mechanism 3 includes a slot 33, which is externally located on the top of the outer casing 1. A protruding ring 32 is slidably connected inside the slot 33. The slot 33 enables a detachable connection between the cover cylinder 31 and the outer casing 1, facilitating subsequent replacement of the filter screen 39 and internal maintenance. The top of the protruding ring 32 is fixedly connected to the cover cylinder 31. The key structure connecting the protruding ring 32, the cover cylinder 31, and the outer casing 1 is the positioning of the cover cylinder 31 through the slot 33. Disassembly is achieved by simply lifting. A fan 4 is fixedly connected inside the cover cylinder 31. Fan 4 generates negative pressure suction, driving air to be drawn in from the bottom air intake area, purified by filter 39, and discharged from the top. It is the power source for airflow circulation. Cover 31 provides installation space for fan 4 and air guide plate 34, and at the same time forms an air outlet channel for clean air. Air guide plate 34 is fixedly connected inside cover 31. Air guide plate 34 guides the purified air, so that the airflow is evenly discharged along a preset path, avoiding airflow turbulence and improving airflow efficiency. The air guide plate 34 is fixedly connected to the outside of fan 4. The bottom of fan 4 is fixedly connected to the outside of fan 4. A connecting post 35 is fixedly connected, which cooperates with the top hole of the filter screen 39 to position the filter screen 39 at the top and prevent the filter screen 39 from shifting upward under the impact of the airflow of the fan 4. The filter screen 39 is slidably connected inside multiple support posts 5, and the top hole of the filter screen 39 is slidably connected to the outside of the connecting post 35. A folded glass fiber layer 38 is fixedly connected inside the filter screen 39. The folded glass fiber layer 38 adopts the structure of HEPA filter screen 39. The folded design greatly increases the filtration area and can efficiently capture small particles. It is the core layer of fine filtration. A medium density polyester fiber layer 37 is fixedly connected inside the folded glass fiber layer 38. The medium density polyester fiber layer 37 acts as a pre-filter layer, intercepting medium-sized impurities such as pollen and pet dander, preventing them from clogging the inner glass fiber layer and extending the overall service life of the filter screen 39. An activated carbon layer 36 is fixedly connected inside the medium density polyester fiber layer 37. The activated carbon layer 36 physically adsorbs gaseous pollutants and odors such as formaldehyde and TVOC through its porous structure, realizing air deodorization and purification and improving air quality. Specifically, when the purification mechanism 3 is working, it first generates negative pressure suction through the fan 4 to draw air in from the bottom of the outer casing 1. The air then enters the filter 39, which is positioned by the support column 5 and the connecting column 35. The air passes through the medium-density polyester fiber layer 37 to intercept medium-sized impurities, the folded glass fiber layer 38 to capture small particles, and the activated carbon layer 36 to adsorb gaseous pollutants and odors, thus completing the purification. The purified air is guided by the air guide plate 34 and discharged along the channel formed by the cover cylinder 31. When the filter 39 needs to be replaced, the cover cylinder 31 is lifted so that the protruding ring 32 at its bottom comes out of the slot 33 at the top of the outer casing 1, and the cover cylinder 31 can be removed to replace the filter 39.

[0016] The implementation principle of this application embodiment is as follows: After the device is powered on, the fan 4 starts to operate and generates negative pressure suction. Air is then drawn in from the air intake area on the bottom outer side of the outer shell 1. The air first comes into contact with the medium-density polyester fiber layer 37 of the outer layer of the filter 39. This layer intercepts smaller pollen particles and pet dander debris in the air through the fiber gaps. The air that has passed through the initial filter then enters the middle layer of the folded glass fiber layer 38, which adopts the HEPA filter 39 structure. The folded shape greatly increases the filtration area and can efficiently capture tiny particles. Finally, the air flows through the activated carbon layer 36. Its porous structure captures gaseous pollutants and odors such as formaldehyde, TVOC, secondhand smoke, and kitchen fumes through physical adsorption, thereby removing odors. The purified air is discharged from the top through the air guide plate 34.

[0017] When the air vents need to be adjusted, manually push the sliding column 25 to slide in the limiting groove inside the housing 1, thereby driving the sliding strip 24 to move. Since the rack on the outer side of the sliding strip 24 meshes with the gear 23 on the outer side of the baffle 22, the sliding of the sliding strip 24 will drive the gear 23 to rotate, and the rotation of the gear 23 will synchronously drive the baffle 22 to rotate around the fixed column 21, ultimately changing the size and tilt angle of the air vents between the baffles 22. When the equipment is not in use or the number of air vents needs to be adjusted, manually push the sliding ring 263, and under the friction of the reinforcing strip 264, make it slide along the outside of the housing 1. The number of air vents can be adjusted by unfolding the expandable windproof cloth built into the protective sleeve 262. When the equipment is not in use, slide the reinforcing strip 264 to the top of the housing 1 to prevent dust from entering the equipment.

[0018] 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.
