Description

Technical Field

[0001] The invention relates to the technical field of air purification, in particular to a unit-type ultraviolet air purifier suitable for central air conditioning. Background Art

[0002] Although ultraviolet air purifiers have been in use in recent years, due to the current technology, some products have simple structures, poor stability and are prone to malfunction. Some have fixed structures, which are inconvenient to install and maintain, and are not easy to clean. Maintenance requires opening the interior, which is inconvenient, and it is difficult to replace parts, which can easily affect the working effect of the product.

[0003] In order to facilitate the disassembly, cleaning and replacement of the ultraviolet air purifier, the existing Chinese patent document CN202020800037.3 discloses a unit-type ultraviolet air purifier suitable for central air conditioning, comprising: a base, a purification device is installed on the upper part of the base, an ultraviolet irradiation device is movably installed above the purification device, a filtering device is movably installed above the ultraviolet irradiation device, and a cover plate is movably installed above the filtering device; a guide rod is installed in the middle of the base, and the other end of the guide rod is fixedly connected to the cover plate; the purification device, the ultraviolet irradiation device and the filtering device are all provided with a disassembly groove, and a buckle is installed in the disassembly groove; the guide rod cooperates with the disassembly groove and the buckle, and the device is detachable in design, which enhances the flexibility of the device, facilitates cleaning and replacement of internal parts, and is easy to install after disassembly, and will not affect the working effect of the device;

[0004] Although the above scheme can realize the rapid disassembly and cleaning of the parts inside the device to ensure the efficient operation of the equipment and extend the service life, in the actual operation process, the purification device, ultraviolet irradiation device and filtering device need to be disassembled one by one. However, in the actual working environment, not all purification devices, ultraviolet irradiation devices and filtering devices need to be maintained. For example, when the purification device at the bottom needs to be maintained, the staff must first take out the ultraviolet irradiation device and filtering device above one by one before they can perform the necessary maintenance work on the purification device. After completing the maintenance work, the purification device, ultraviolet irradiation device and filtering device need to be reinstalled into the device one by one. This process is not only time-consuming and labor-intensive, but also prone to operational errors during disassembly and installation, which increases the complexity and workload of maintenance.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1 - Figure 3, a unit-type ultraviolet air purifier suitable for central air conditioning in the figure comprises three groups of mounting boxes 1 for storing various functional devices stacked together in an array from top to bottom and an air-conditioning air supply duct 101, the rear side of the mounting box 1 is provided with an opening, and a sealing cover plate 2 is rotatably installed on the inner side of the top of the opening; it also includes: a movable plate 3 arranged horizontally in the mounting box 1, a positioning unit 4 is installed on the top of the movable plate 3, and a purification device, an ultraviolet irradiation device and a filtering device are fixedly connected to the three movable plates 3 through the positioning units 4 respectively (for the specific structures of the purification device, the ultraviolet irradiation device and the filtering device, please refer to the Chinese patent document CN202020800037.3), linkage units 5 for realizing synchronous movement of the sealing cover plate 2 and the movable plate 3 are provided on both sides of the box, and a driving unit 6 transmission-connected to the linkage unit 5 is provided at the bottom of the movable plate 3.

[0031] In the present solution, when it is necessary to maintain or disassemble the purification device, ultraviolet irradiation device and filtering device inside the air purifier, the designed linkage unit 5 and driving unit 6 cooperate with each other to realize the synchronous linkage of the sealing cover plate 2 and the movable plate 3, that is, the sealing cover plate 2 will automatically rotate and open. At the same time, the movable plate 3 will work together to move the various devices at the corresponding positions out of the installation box 1 as a whole, and the positioning mechanism will automatically release the fixing effect on each device during the movement of the movable plate 3, so that the various devices after being moved out can be easily disassembled. In this way, when performing maintenance and disassembly work, the staff does not need to take out each device one by one, which greatly simplifies the operation process, makes the maintenance and disassembly of the device more convenient and quick, and reduces the errors and damages that may occur during the maintenance process, ensuring the stable operation and service life of the equipment.

[0032] For further information, see Figure 3 and Figure 4 The positioning unit 4 includes a square table 7 fixed on the top of the movable plate 3, a positioning block 8 is slidably inserted in the square table 7, and the three positioning blocks 8 are respectively fixedly connected to the bottom of the purification device, the ultraviolet irradiation device and the filtering device. The four sides of the positioning block 8 are provided with positioning holes 9, and a positioning rod 10 is slidably inserted in the positioning hole 9. The end of the positioning rod 10 away from the positioning hole 9 slides through the outside of the positioning table and is fixedly connected with a moving rod 11. A transmission member 12 for driving it to move is fixed at one end of the moving rod 11. The transmission member 12 is provided with four groups, and the top of the movable plate 3 is rotatably connected with an outer gear ring 13 for synchronously driving the four groups of the transmission members 12.

[0033] Among them, see Figure 4The transmission member 12 includes a No. 1 gear 14 meshing with the outer gear ring 13, a No. 1 rotating shaft 15 is fixedly sleeved in the middle hole of the No. 1 gear 14, and the No. 1 rotating shaft 15 is rotatably connected to a No. 1 limiting seat 16 through a bearing, and a No. 1 L-shaped plate 17 is fixed on one end of the No. 1 limiting seat 16, and the bottom of the No. 1 L-shaped plate 17 is fixed on the movable plate 3, and a No. 2 gear 18 is fixedly sleeved on the top of the No. 1 rotating shaft 15, and a No. 3 gear 19 is meshed on one side of the No. 2 gear 18, and a No. 2 rotating shaft 20 is fixedly sleeved in the middle hole of the No. 3 gear 19, and the No. 2 rotating shaft 20 is rotatably connected to the No. 1 limiting seat 16 through a bearing, and a rotating disk 21 is fixed on the top of the No. 3 gear 19, and a sliding pin 22 is fixed at the eccentric position of the top of the rotating disk 21, and a slot plate 23 is slidably sleeved on the outer side of the sliding pin 22, and the middle position of one side of the slot plate 23 is fixedly connected to the moving rod 11.

[0034] Also, see Figure 8 A first transmission rack 24 is fixed to an inner wall of one side of the installation box 1 , and one side of the first transmission rack 24 is meshedly connected with one of the first gears 14 .

[0035] Principle of disassembling the device: During the outward movement of the moving plate 3, one of the No. 1 gears 14 will move to a position meshing with the No. 1 transmission rack 24. At this time, the moving plate 3 continues to move outward, and the No. 1 gear 14 will rotate outside the No. 1 transmission rack 24, thereby driving the No. 1 rotating shaft 15 to rotate, the No. 1 rotating shaft 15 drives the No. 2 gear 18 to rotate, the No. 2 gear 18 drives the No. 3 gear 19 to rotate, and the No. 3 gear 19 drives the rotating disk 21 to rotate. Since the number of teeth of the No. 1 gear 14 and the No. 1 transmission rack 24 is equal, The number one gear 14 rotates only one circle, while the number three gear 19 rotates half a circle, driving the slot plate 23 to move from one extreme position to another extreme position on the rotating disk 21. At the same time, the moving rod 11 and the positioning rod 10 are also driven to move together. The positioning rod 10 is just completely moved out of the positioning hole 9, thereby releasing the locking effect on the positioning block 8. At the same time, because the four number one gears 14 are meshed with the outer ring gear 13, the four number one gears 14 will rotate at the same speed and the same angle, ensuring that the moving rods 11 at the four positions can move synchronously by equal distances.

[0036] For further information, see Figure 8 Slide bars 42 are fixed at both ends of the movable plate 3, and a slide rail 43 slidably connected to the slide bars 42 is fixed on the inner wall of the installation box 1. When the movable plate 3 is moving, it can be more stable and reduce shaking and deviation.

[0037] For further information, see Figure 4A second L-shaped plate 44 is fixed to the outer side of the square platform 7, and a slide groove 45 is opened on the top of the second L-shaped plate 44. A slide rod 46 is slidably connected in the slide groove 45. The top of the slide rod 46 is fixedly connected to the moving rod 11. When the moving rod 11 moves, it will drive the slide rod 46 to slide in the slide groove 45, thereby ensuring that the moving rod 11 can complete stable linear motion.

[0038] Example 2: Please refer to Figure 5 - Figure 7 This embodiment further explains the first embodiment, and the difference lies in optimizing the sealing cover plate 2 and the movable plate 3.

[0039] Specifically, the linkage unit 5 includes a third rotating shaft 25, one end of the third rotating shaft 25 is rotatably connected to the installation box 1 through a bearing, the outer side of the third rotating shaft 25 is fixedly sleeved with a first pulley 26, the first pulley 26 is connected to a second pulley 27 through a synchronous belt transmission, a fourth rotating shaft 28 is fixedly sleeved in the middle hole of the second pulley 27, one end of the fourth rotating shaft 28 is rotatably connected to the installation box 1 through a bearing, and an incomplete gear 29 is also fixedly sleeved on the outer side of the fourth rotating shaft 28, and one side of the incomplete gear 29 is provided with There is a sector gear 30, a fifth rotating shaft 31 is fixedly sleeved in the middle hole of the sector gear 30, one end of the fifth rotating shaft 31 is rotatably connected to the mounting box 1 through a bearing, a third pulley 32 is also fixedly sleeved on the outer side of the fifth rotating shaft 31, the third pulley 32 is connected to the fourth pulley 33 through a synchronous belt transmission, a sixth rotating shaft 34 is fixed in the middle hole of the fourth pulley 33, one end of the sixth rotating shaft 34 is fixedly connected to the end of the sealing cover plate 2, and the driving unit 6 is arranged between the sealing cover plate 2 and the third rotating shaft 25;

[0040] At the same time, the driving unit 6 includes a worm 35, both sides of which are rotatably connected with a No. 2 limit seat 36, one end of the No. 2 limit seat 36 is fixed to the outer wall of the installation box 1, and a rotating block 37 is fixed to one end of the worm 35. A worm wheel 38 is meshed on the upper side of the worm 35, and the worm wheel 38 is fixedly sleeved with the No. 3 rotating shaft 25. The No. 3 rotating shaft 25 passes through the interior of the installation box 1 and is rotatably connected with the installation box 1 through a bearing. A No. 2 transmission rack 39 is fixed to the bottom of the movable plate 3, and a No. 4 gear 40 is meshed at the bottom of the No. 2 transmission rack 39, and the No. 4 gear 40 is fixedly sleeved with the outer side of the No. 3 rotating shaft 25.

[0041] The principle of linkage between the moving plate 3 and the sealing cover plate 2: Please refer to Figure 1-Figure 9, the personnel drives the worm 35 to rotate through the rotating block 37, the worm 35 drives the worm wheel 38 to rotate, the worm wheel 38 drives the third rotating shaft 25 to rotate, the third rotating shaft 25 will drive the fourth gear 40 to rotate, the fourth gear 40 drives the second transmission rack 39 to move, because the gear ratio of the second transmission rack 39 and the fourth gear 40 is one to three, so the fourth gear 40 will rotate three times before it is completely disengaged from the second transmission rack 39, and before the two are disengaged, the moving plate 3 is just moved out of the installation box 1. The appropriate position allows the device to be exposed to the personnel's field of vision, and the third rotating shaft 25 will The first pulley 26 is driven to rotate, the first pulley 26 drives the second pulley 27 to rotate, the second pulley 27 drives the fourth shaft 28 to rotate, the fourth shaft 28 drives the incomplete gear 29 to rotate, the toothed side of the incomplete gear 29 will mesh with the fan gear 30, thereby driving the fan gear 30 to rotate, the fan gear 30 drives the fifth shaft 31 to rotate, the fifth shaft 31 drives the fourth pulley 33 to rotate through the third pulley 32, and then drives the sixth shaft 34 to rotate, the sixth shaft 34 drives the sealing cover plate 2 to rotate, so that when the movable plate 3 moves outward, the sealing cover plate 2 is opened together.

[0042] At the same time, it is worth noting that the diameter ratio of the No. 1 pulley 26 to the No. 2 pulley 27 is 1:3, and the diameter ratio of the incomplete gear 29 to the fan gear 30 is 3:8. In the process of the No. 3 rotating shaft 25 rotating two circles, the No. 4 gear 40 also rotates two circles. At this time, the No. 4 gear 40 and the No. 2 transmission rack 39 have not yet fallen out of engagement, and the No. 2 pulley 27 has just rotated two-thirds of a circle, and the incomplete gear 29 has also rotated two-thirds of a circle. Two-thirds of the circumference of the incomplete gear 29 is distributed with teeth, and these two-thirds of the teeth will only engage with the fan gear 30 during the rotation process. The toothless part will not generate a linkage relationship with the sector gear 30 when rotating. Since the diameter ratio of the incomplete gear 29 and the sector gear 30 is three to eight, the sector gear 30 will rotate a quarter of a circle during the process of the incomplete gear 29 rotating two-thirds of a circle, thereby driving the sealing cover plate 2 to rotate ninety degrees, that is, before the incomplete gear 29 and the sector gear 30 fall out of engagement, the sealing cover plate 2 automatically rotates ninety degrees, and the fourth gear 40 will continue to rotate one circle and the sealing cover plate 2 will not rotate anymore, so that the moving distance of the movable plate 3 corresponds to the rotation angle of the sealing cover plate 2.

[0043] Example 3: Please refer to Figure 6 This embodiment further illustrates other embodiments, and the difference lies in that the rotation mode of the rotating block 37 is optimized.

[0044] Specifically, the driving unit 6 includes a worm 35, both sides of the worm 35 are rotatably connected with a No. 2 limit seat 36, one end of the No. 2 limit seat 36 is fixed to the outer wall of the installation box 1, one end of the worm 35 is fixed with a rotating block 37, the upper side of the worm 35 is meshed with a worm wheel 38, the worm wheel 38 is fixedly sleeved with the No. 3 rotating shaft 25, the No. 3 rotating shaft 25 passes through the interior of the installation box 1 and is rotatably connected to the installation box 1 through a bearing, and a No. 2 transmission rack 39 is fixed to the bottom of the movable plate 3, and the No. 2 A number four gear 40 is meshed with the bottom of the number four transmission rack 39, and the number four gear 40 is fixedly sleeved with the outer side of the number three rotating shaft 25; an inner hexagonal slot 41 is provided at the end of the rotating block 37 away from the worm 35, and the size of the inner hexagonal slot 41 is adapted to an inner hexagonal wrench of corresponding size. A person matches the inner hexagonal slot 41 with the inner hexagonal slot 41, and then rotates the inner hexagonal wrench, thereby driving the rotating block 37 to rotate, and the rotating block 37 drives the worm 35 to rotate, and the worm 35 drives the worm wheel 38 to rotate, thereby saving effort and being more convenient when inputting driving force.

[0045] Example 4: Please refer to Fig.10 This implementation further illustrates other embodiments, the difference being that the installation scenario of the purifier is optimized.

[0046] A unit-type ultraviolet air purifier suitable for central air conditioning comprises three groups of mounting boxes 1 stacked together in an array from top to bottom for storing various functional devices and an air conditioning air supply duct 101. The three groups of mounting boxes 1 are connected to the air conditioning air supply duct 101 through a pull-out guide rail. A through hole 102 for the entire purifier to be removed as a whole is opened on one side of the air conditioning air supply duct 101, and a sealing door 103 adapted to the through hole is fixed at one end of the pull-out guide rail. Before cleaning the purifier, a person needs to pull the sealing door 103. , so that the entire unit-type ultraviolet air purifier is moved out of the air-conditioning air supply duct 101. The pull-out disassembly method is more convenient for disassembly and maintenance of the purifier in the air-conditioning air supply duct 101. Then, by utilizing the designed linkage unit 5 and the driving unit 6 to cooperate with each other, the sealing cover plate 2 and the movable plate 3 can be synchronously linked, that is, the sealing cover plate 2 will automatically rotate and open. At the same time, the movable plate 3 will work together to move the various devices at the corresponding positions out of the installation box 1 as a whole, thereby facilitating the cleaning and maintenance of the ultraviolet air purifier.
