Description

Technical Field

[0001] This invention belongs to the field of desk technology, and more specifically, relates to an energy-saving and environmentally friendly desk that can purify the air. Background Technology

[0002] This energy-efficient and environmentally friendly desk with air purification is a modern office and study furniture piece that integrates innovative technology and green concepts. It cleverly incorporates a high-efficiency air purification function, effectively filtering dust, pollen, and harmful gases, significantly improving the air quality around the user. At the same time, the desk is made entirely of environmentally friendly and renewable materials, reducing the burden on the environment from the source.

[0003] Currently, energy-saving and environmentally friendly desks are highly sought after. However, a thorny issue arises during their use: the filters equipped with these desks accumulate a large amount of dust and grime over time, requiring timely replacement or cleaning to ensure their proper function. The frustrating problem is that existing filter designs are flawed, tightly integrated with the desk body, and lack a convenient disassembly mechanism, causing significant inconvenience for users' daily maintenance. Summary of the Invention

[0004] In response to the problems in related technologies, this invention proposes an energy-saving and environmentally friendly desk with air purification capabilities to overcome the aforementioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to an energy-saving and environmentally friendly desk with air purification capabilities. The desk includes a main body with an air intake box cleverly integrated beneath it. Symmetrical locking mechanisms are arranged on both sides of the air intake box. Each locking mechanism includes a fixing component fixedly mounted on the air intake box. A locking rod is slidably connected inside the fixing component. Slider blocks are fixedly mounted on both sides of the locking rod. One end of a return spring is fixedly mounted on each slider, and the other end of the return spring is fixedly mounted on the inner wall of the fixing component. The locking rod engages with a locking hole located on a connecting rod. The connecting rod is slidably connected inside the fixing component and fixedly mounted on a first filter screen. Both the locking rod and the connecting rod have rounded corners, which facilitates smoother installation and removal of the first filter screen, reducing friction and jamming. The air intake box is connected to the filter box via a first connecting pipe, and the filter box is connected to the exhaust box via a second connecting pipe. The exhaust box contains a guide mechanism for precisely controlling the direction of exhaust airflow to meet the user's airflow needs in different scenarios.

[0006] Furthermore, the snap-fit ​​mechanism is provided in two sets, with identical parts and installation methods. This symmetrical design not only enhances the stability of the structure but also improves the overall balance. The suction box is fixedly installed at the bottom of the drawer, and the drawer is fixedly installed at the bottom of the desk. This layout makes full use of the space under the desk, without affecting the normal use of the desk, and facilitates the maintenance and repair of the suction box.

[0007] Furthermore, the filter box is fixedly mounted on the drawer, ensuring its stability. The guiding mechanism includes a second filter screen slidably connected inside the exhaust box, which further filters the air and improves the purification effect. The exhaust box is horizontally rotatably equipped with several first guide vanes, which are positioned in front of the second filter screen. By adjusting the angle of the first guide vanes, the horizontal flow direction of the air can be changed.

[0008] Furthermore, each of the rotating shafts of several first guide vanes is fixedly equipped with a first gear, and these first gears are connected by a first gear belt drive. This gear drive method allows multiple first guide vanes to rotate synchronously, making operation more convenient. One of the first gears is fixedly equipped with a first handle, which the user can rotate to adjust the angle of the first guide vane.

[0009] Furthermore, the exhaust box is vertically rotatably equipped with several second guide vanes. Each of the second guide vanes has a second gear fixedly mounted on its rotation shaft. These second gears are connected via a second gear belt drive. This design allows the multiple second guide vanes to rotate synchronously. One of the second gears is fixedly equipped with a second handle, allowing the user to adjust the angle of the second guide vane by rotating the handle, thereby changing the direction of airflow in the vertical direction.

[0010] Furthermore, a movable rod is fixedly installed at the bottom of the desk, and the movable rod is slidably connected inside the fixed rod. This design allows the height of the desk to be adjusted. A threaded rod is rotatably installed inside the fixed rod, and the movable rod is threadedly connected to the threaded rod. By rotating the threaded rod, the movable rod can be moved up and down within the fixed rod, thereby achieving the adjustment of the desk height.

[0011] Furthermore, a worm gear is fixedly installed on the threaded rod, the worm gear meshes with a worm, and the worm is rotatably mounted on the fixed rod. The worm gear transmission has self-locking properties, which can ensure that the desk remains stable after being adjusted to a suitable height and will not easily change its height due to external forces.

[0012] Furthermore, four of each of the movable rod, fixed rod, threaded rod, and worm gear are provided, and this four-corner support design enhances the stability of the desk. Two worm gears are provided, each with a transmission wheel fixedly mounted at one end. The two transmission wheels are connected by a transmission belt. One end of one worm gear is fixedly mounted with the output end of a drive motor, which drives one of the worm gears to rotate. Through the transmission wheel and the transmission belt, the two worm gears rotate synchronously, thereby enabling the desk to be raised and lowered simultaneously at all four corners, making operation more convenient and stable.

[0013] Compared with the prior art, the present invention has the following advantages: 1. This desk features comprehensive air purification capabilities. After drawing in ambient air, it passes through multiple layers of filtration in the intake and exhaust boxes, effectively removing fine particles and harmful substances to create a healthy breathing environment for the user. Simultaneously, the exhaust box is equipped with horizontal and vertical airflow deflectors. Users can adjust the angles of the first and second deflectors by rotating the first and second handles, respectively, to precisely guide the purified air horizontally and vertically. This meets the personalized airflow needs of users in different scenarios, greatly enhancing the user experience.

[0014] 2. The desk's base employs a lifting structure comprised of movable rods, fixed rods, threaded rods, worm gears, and worm shafts. These four components form a four-corner support, enhancing the desk's stability. A drive motor rotates the worm shafts, which, via a transmission wheel and belt, cause two worm shafts to rotate synchronously. This, in turn, drives the four threaded rods to rotate synchronously, allowing the desk to be raised and lowered simultaneously at all four corners. This accommodates users of different heights, improving comfort. Furthermore, the worm gear transmission has a self-locking mechanism, ensuring the desk remains stable once adjusted to a suitable height, preventing height changes during use.

[0015] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0020] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0021] Please see Figures 1-7As shown, this invention relates to an energy-saving and environmentally friendly desk with air purification capabilities. It includes a desk 1, with an air intake box 2 located beneath the desk 1. This air intake box 2 serves as the starting point for air purification, drawing in surrounding air for further processing. The air intake box 2 has locking mechanisms on both sides, each including a fixing member 3 fixedly mounted on the air intake box 2. The fixing member 3 provides a stable support frame for the entire locking structure. A locking rod 4 is slidably connected inside the fixing member 3, allowing for flexible movement within the fixing member 3 to achieve locking and unlocking functions. Slider blocks 5 are fixedly mounted on both sides of the locking rod 4, serving as guides to ensure stability during movement. One end of a return spring 6 is fixedly mounted on each slider 5, and the other end of the return spring 6 is fixedly mounted on the inner wall of the fixing member 3. The return spring 6 provides a reset force to the locking rod 4, allowing it to return to its initial position when no external force is applied. The locking rod 4 engages with the locking hole 7, which is located on the connecting rod 8. The connecting rod 8 is slidably connected inside the fixing member 3 and is fixedly installed on the first filter screen 31. Through the engagement of the locking rod 4 and the locking hole 7, the first filter screen 31 can be securely installed on the air intake box 2, and is easy to disassemble and replace. Both the locking rod 4 and the connecting rod 8 have rounded corners at one end, which makes the engagement process smoother and reduces friction and collision. The air intake box 2 is connected to the filter box 10 through the first connecting pipe 9, and the filter box 10 is connected to the exhaust box 12 through the second connecting pipe 11. The exhaust box 12 is equipped with a guide mechanism to precisely control the direction of exhaust air to meet the user's airflow needs in different scenarios.

[0022] The working principle of the energy-saving and environmentally friendly desk with air purification proposed in this invention is as follows: During operation, the air intake box 2, as the starting point of air purification, starts to draw in the surrounding air. After entering the air intake box 2, the drawn-in air flows to the filter box 10, which is connected to it through the first connecting pipe 9, and undergoes preliminary filtration treatment in the filter box 10.

[0023] During the air intake process of the air intake box 2, the locking mechanisms on both sides are in a stable state. In the locking mechanism, the fixing member 3, fixedly installed on the air intake box 2, provides a stable support frame for the whole. The locking rod 4, slidably connected inside the fixing member 3, maintains its initial position. At this time, under the action of the return spring 6, the locking rod 4 is locked with the locking hole 7 opened on the connecting rod 8. The connecting rod 8 is fixedly installed on the first filter screen 31, so the first filter screen 31 is securely installed inside the air intake box 2, performing preliminary filtration of the intake air. The sliders 5 on both sides of the locking rod 4 act as guides, ensuring stable movement of the locking rod 4. One end of the return spring 6 is connected to the slider 5, and the other end is fixed to the inner wall of the fixing member 3, providing the return force for the locking rod 4. The rounded corner design of one end of the locking rod 4 and the connecting rod 8 makes the locking process smoother.

[0024] When it is necessary to disassemble and replace the first filter screen 31, hold the part of the clamping rod 4 located outside the fixing member 3 and pull the clamping rod 4 outward. After the clamping rod 4 is subjected to force, it drives the slider 5 to slide in a predetermined direction within the fixing member 3, and at the same time, the return spring 6 is stretched. As the clamping rod 4 moves outward, it gradually disengages from the locking hole 7 on the connecting rod 8. When the clamping rod 4 is completely disengaged from the locking hole 7, the connecting rod 8 loses its locking constraint. At this time, the connecting rod 8 can be pulled out from inside the fixing member 3. Since the connecting rod 8 is fixedly installed on the first filter screen 31, the first filter screen 31 is also removed from the air intake box 2.

[0025] When reinstalling the new first filter 31, first insert the connecting rod 8, on which the new first filter 31 is fixedly installed, into the fixing part 3. During insertion, one end of the connecting rod 8 will press against the rounded end of the locking rod 4, causing the locking rod 4 to retract into the fixing part 3, while the return spring 6 is compressed. When the connecting rod 8 is inserted into the appropriate position and the locking hole 7 is aligned with the locking rod 4, the locking rod 4 pops out and locks into the locking hole 7 under the elastic force of the return spring 6, thus achieving a stable installation of the new first filter 31.

[0026] After initial filtration by the filter box 10, the air flows into the exhaust box 12 through the second connecting pipe 11. The guide mechanism inside the exhaust box 12 then comes into play, precisely controlling the exhaust direction and discharging the purified air in the set direction to meet the user's airflow needs in different scenarios.

[0027] In one embodiment, the aforementioned snap-fit ​​mechanism is provided in two sets, with identical parts and installation methods. This symmetrical design enhances the stability and reliability of the structure. The suction box 2 is fixedly installed at the bottom of the drawer 13, which is in turn fixedly installed at the bottom of the desk 1. This layout makes full use of the space under the desk, without affecting the normal use of the desk, and facilitates the maintenance and repair of the suction box 2. At the same time, the drawer 13 can also be used to store items.

[0028] In one embodiment, the filter box 10 is fixedly mounted on the drawer 13 to ensure its stability and prevent shaking during use from affecting the filtration effect. The guiding mechanism includes a second filter screen 14 slidably connected inside the exhaust box 12. The second filter screen 14 further filters the air, improving the purification effect and removing fine particles and harmful substances from the air. The exhaust box 12 is horizontally rotatably equipped with several first guide vanes 15, which are positioned in front of the second filter screen 14. By adjusting the angle of the first guide vanes 15, the horizontal airflow direction can be changed, allowing the purified air to be blown out in the direction desired by the user.

[0029] In one embodiment, for the aforementioned first guide vanes 15, each of the rotating shafts of several first guide vanes 15 is fixedly equipped with a first gear 16, and the several first gears 16 are connected by a first gear belt 17. This gear transmission method enables multiple first guide vanes 15 to rotate synchronously, making operation more convenient. The angle of all first guide vanes 15 can be adjusted by rotating only one component. One of the first gears 16 is fixedly equipped with a first handle 18. The user can rotate the first handle 18 to drive the first gear 16 to rotate, thereby adjusting the angle of the first guide vane 15 to meet different usage needs.

[0030] In one embodiment, the exhaust box 12 is vertically rotatably equipped with several second guide vanes 19. Each of the second guide vanes 19 has a second gear 20 fixedly mounted on its rotating shaft. These second gears 20 are connected via a second gear belt 21. This design allows the multiple second guide vanes 19 to rotate synchronously, facilitating user adjustment of the airflow direction in the vertical direction. One of the second gears 20 is fixedly mounted with a second handle 22. The user can rotate the second handle 22 to drive the second gear 20, thereby changing the angle of the second guide vane 19 and achieving precise vertical airflow guidance.

[0031] In one embodiment, for the desk 1 described above, a movable rod 23 is fixedly installed at the bottom of the desk 1. The movable rod 23 is slidably connected inside the fixed rod 24. This design allows the height of the desk 1 to be adjusted to accommodate users of different heights and improve user comfort. A threaded rod 25 is rotatably installed inside the fixed rod 24. The movable rod 23 is threadedly connected to the threaded rod 25. By rotating the threaded rod 25, the movable rod 23 can be moved up and down within the fixed rod 24, thereby adjusting the height of the desk 1. This adjustment method is stable and reliable, and can precisely control the height of the desk 1.

[0032] In one embodiment, the threaded rod 25 is fixedly mounted with a worm gear 26, which meshes with a worm 27. The worm 27 is rotatably mounted on a fixed rod 24. The worm gear transmission has self-locking properties, which can ensure that the desk 1 remains stable after being adjusted to a suitable height and will not easily change its height due to external forces, thus ensuring safety and stability during use.

[0033] In one embodiment, four movable rods 23, four fixed rods 24, four threaded rods 25, and four worm gears 26 are provided for the aforementioned movable rod 23. This four-corner support design enhances the stability of the desk 1, ensuring that the desk 1 remains stable during height adjustment and use. Two worm gears 27 are provided, each with a transmission wheel 28 fixedly mounted at one end. The two transmission wheels 28 are connected by a transmission belt 29. One end of one worm gear 27 is fixedly mounted with the output end of a drive motor 30. The drive motor 30 can drive one of the worm gears 27 to rotate. Through the transmission of the transmission wheel 28 and the transmission belt 29, the two worm gears 27 rotate synchronously, thereby driving the four threaded rods 25 to rotate synchronously, enabling the desk 1 to be raised and lowered simultaneously from all four corners. This makes operation more convenient and stable, providing a more comfortable user experience.

[0034] The working principle of this energy-saving and environmentally friendly desk with air purification capability is as follows: During operation, the air intake box 2 is activated, acting as the starting point for air purification by drawing in surrounding air. Two sets of snap-fit ​​mechanisms are provided, with identical parts and installation methods; the symmetrical design enhances structural stability and reliability. The air intake box 2 is fixedly installed at the bottom of drawer 13, which is also fixedly installed at the bottom of the desk 1. This fully utilizes the space under the desk, does not affect normal use, and facilitates maintenance and repair. Drawer 13 can also be used for storage.

[0035] After being drawn in, the air enters the intake box 2 and flows into the filter box 10 through the first connecting pipe 9. The filter box 10 is fixedly installed on the drawer 13 to ensure stability and prevent shaking from affecting the filtration effect. After being initially filtered in the filter box 10, the air enters the exhaust box 12 through the second connecting pipe 11.

[0036] The guiding mechanism inside the exhaust box 12 functions, and the second filter 14, which is slidably connected inside the exhaust box 12, further filters the air, improves the purification effect, and removes fine particles and harmful substances. Several first guide vanes 15 are horizontally rotatable and mounted in front of the second filter 14. Each of the first guide vanes 15 has a first gear 16 fixedly mounted on its rotating shaft. These first gears 16 are connected by a first gear belt 17. One of the first gears 16 is fixedly mounted with a first handle 18. When the user rotates the first handle 18, it drives the first gear 16 to rotate, causing the multiple first guide vanes 15 to rotate synchronously via the first gear belt 17. This adjusts their angle, changes the horizontal airflow direction, and ensures that the purified air is blown out in the direction desired by the user.

[0037] The exhaust box 12 is vertically rotatably equipped with several second guide vanes 19. Each of the second guide vanes 19 has a rotating shaft with a second gear 20 fixedly mounted on it. These second gears 20 are connected via a second gear belt 21. One of the second gears 20 is fixedly mounted with a second handle 22. When the user rotates the second handle 22, it drives the second gear 20 to rotate, causing the multiple second guide vanes 19 to rotate synchronously via the second gear belt 21, adjusting their angles and achieving precise vertical airflow guidance.

[0038] A movable rod 23 is fixedly installed at the bottom of the desk 1. The movable rod 23 is slidably connected inside the fixed rod 24. A threaded rod 25 is rotatably installed inside the fixed rod 24, and the movable rod 23 is threadedly connected to the threaded rod 25. A worm gear 26 is fixedly installed on the threaded rod 25, and the worm gear 26 meshes with a worm 27, which is rotatably installed on the fixed rod 24. Four movable rods 23, four fixed rods 24, four threaded rods 25, and four worm gears 26 are provided to form a four-corner support, enhancing the stability of the desk 1. There are two worms 27, and a transmission wheel 28 is fixedly installed at one end of each worm 27. The two transmission wheels 28 are connected by a transmission belt 29. The output end of a drive motor 30 is fixedly installed at one end of one of the worms 27. When the drive motor 30 starts, it drives one of the worm gears 27 to rotate. Through the transmission wheel 28 and the transmission belt 29, the two worm gears 27 rotate synchronously, which in turn drives the four threaded rods 25 to rotate synchronously. This causes the moving rod 23 to move up and down within the fixed rod 24, allowing the four corners of the desk 1 to rise and fall simultaneously. This accommodates users of different heights, improves user comfort, and the worm gear transmission has a self-locking property, ensuring that the desk 1 remains stable after being adjusted to the appropriate height.
