DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0021] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0022] like Figures 1 to 14As shown, the air purifier with fan function includes a housing 1, a cover 20, an arc tube 17, a linkage mechanism 3, a connecting mechanism 4, a first fan 16, a cylinder 10, a rotating shaft 22, a fan duct 14 and a purification duct 13. The cover 20 is buckled on the housing 1, and the cover 20 and the housing 1 are detachably connected, and the cover 20 and the housing 1 can be fixed by bolts. The arc tube 17 passes through the cover 20. When the arc tube 17 passes through the cover 20 and rotates relative to the cover 20, the arc tube 17 rotates with the center of the arc tube 17 as the axis. The arc tube 17 is connected to the linkage mechanism 3 through the connecting mechanism 4, the end of the arc tube 17 is connected to the first fan 16, the cylinder 10 is connected to the housing 1, and the rotating shaft 22 is rotatably connected to the cylinder 10. The fan duct 14 and the purification duct 13 are installed on the rotating shaft 22. The fan duct 14 and the purification duct 13 are distributed along the circumference of the rotating shaft 22. The angle between the axis of the fan duct 14 and the purification duct 13 and the line connecting the center of the rotating shaft 22 is less than 30 degrees. The fan duct 14 and the purification duct 13 play different roles in actual use. The fan duct 14 is mainly aimed at increasing the air flow efficiency. It is usually a larger cross-section and direct ventilation. The purpose is to quickly promote air flow and provide a cool effect. The purification duct 13 is provided with multiple filtering structures inside. The airflow passes through multiple filtering structures to remove particulate matter and pollutants in the air. The path design of the airflow passing through multiple filtering structures can improve the purification effect of the air. A second fan 15 is provided below the rotating shaft 22. The second fan 15 is a fan with adjustable speed. The second fan 15 is arranged at the center of the cylinder 10. When the arc tube 17 is rotated, the arc tube 17 drives the linkage mechanism 3 to move through the connection mechanism 4 , and the linkage mechanism 3 is used to drive the rotating shaft 22 to rotate to achieve the switching between the purification air duct 13 and the fan air duct 14 .

[0023] In actual use, when the arc tube 17 is not rotated, the purifier is in purification mode, and the purification air duct 13 is set at the center of the cylinder 10. When the fan mode needs to be switched, the user rotates the arc tube 17, and the arc tube 17 indirectly drives the linkage mechanism 3 to move by the connection mechanism 4 when rotating, and drives the rotating shaft 22 to rotate by the linkage mechanism 3, so as to switch the purification air duct 13 to the fan air duct 14. At this time, the fan air duct 14 is located at the center of the cylinder 10. After completing the switching of the fan air duct 14, the first fan 16 and the second fan 15 are started, and the inclined first fan 16 blows toward the user to reduce the temperature. Among them, in the purification mode, the second fan 15 is at a low speed, which realizes the purification of indoor air, and in the fan mode, the second fan 15 is at a high speed. A refrigeration structure or a cooling structure can be set in the fan air duct 14, and the started second fan 15 assists the first fan 16 to blow cold air to a position close to the bottom end of the arc tube 17, and the first fan 16 blows cold air to the human body for cooling, thereby improving the cooling effect of the fan. The second fan 15 can assist the first fan 16 to improve the heat dissipation effect while purifying the air. The air duct is switched by rotating the arc tube 17, thereby realizing the rapid switching between the fan mode and the purification mode. One purifier meets two usage requirements, thereby improving the application range of the air purifier.

[0024] In this embodiment, the linkage mechanism 3 includes a crossbeam 301, a telescopic cylinder 302, a telescopic rod 303, a back plate 304, a rack 305, a stopper 306, a gear ring 307, a slider 308, a slide bar 309 and a first spring 310. The crossbeam 301 is rotatably connected to the telescopic cylinder 302, and the crossbeam 301 can rotate relative to the telescopic cylinder 302. The interior of the telescopic cylinder 302 is slidably connected to the telescopic rod 303, and the telescopic cylinder 302 can be lifted and lowered relative to the telescopic rod 303. The telescopic rod 303 is connected to the slider 308, and the slider 308 is slidably connected to the slide bar 309. A first spring 310 is connected between the slider 308 and the back plate 304. The back plate 304 is connected to the rack 305, and the rack 305 is meshedly connected to the gear ring 307, and the gear ring 307 is connected to the rotating shaft 22. The limit block 306 is slidably connected to the back plate 304 , and the limit block 306 limits the back plate 304 , restricting the back plate 304 to move only in a straight line.

[0025] In actual use, the arc tube 17 will drive the cross beam 301 to rotate synchronously through the connecting mechanism 4. The cross beam 301 will drive the slider 308, the telescopic cylinder 302 and the telescopic rod 303 to move horizontally during the rotation. The cross beam 301 is displaced in the vertical and horizontal directions during the rotation following the arc tube 17. The lifting movement of the telescopic cylinder 302 relative to the telescopic rod 303 compensates for the displacement of the cross beam 301 in the vertical direction. At the same time, a first spring 310 is provided in the direction of movement of the slider 308. The slider 308 and the back plate 304 are supported to move synchronously by the elastic force of the first spring 310. The rack 305 is driven to move during the movement of the back plate 304. The rack 305 engages with the gear ring 307 on the rotating shaft 22 during the movement to rotate. The rotating shaft 22 causes the fan duct 14 to move to the center of the cylinder 10 during the rotation. At this time, the other end face of the back plate 304 is in contact with the limit block 306, and the limit block 306 limits the further movement of the back plate 304. At this time, the slider 308 no longer moves synchronously with the back plate 304, and the slider 308 compresses the first spring 310. The purpose of setting the slider 308 to compress the first spring 310 here is to not affect the rotation of the arc tube 17 into place after switching the air duct. After rotating into place, start the first fan 16 and the second fan 15, and the inclined first fan 16 blows towards the user to reduce the temperature. Compared with the traditional method of using electric equipment control, the linkage mechanism 3 using a purely mechanical structure ensures the reliability of the air purifier during operation, and the failure rate is lower than that of the traditional electric equipment control method, which also controls the maintenance cost of the subsequent use of the air purifier.

[0026] In this embodiment, the cover body 20 is rotatably connected to the outer shell 1 through the pin shaft 21, and the cover body 20 can rotate relative to the outer shell 1, so as to realize the replacement of the internal filtering structure of the purification air duct 13. The connecting mechanism 4 includes a magnetic block 401, a slot 402 and an arc-shaped plug rod 403. The arc-shaped plug rod 403 is connected to the arc tube 17, and the arc surface center of the arc-shaped plug rod 403 is coaxially arranged with the central axis of the pin shaft 21. The slot 402 is processed on the cross beam 301, and the arc-shaped plug rod 403 passes through the slot 402. The shape of the arc-shaped plug rod 403 matches the shape of the slot 402. The magnetic block 401 fits with the cross beam 301; in this embodiment, the material of the cross beam 301 is iron, and the magnetic block 401 can be attracted to the cross beam 301.

[0027] When the filter structure in the purification air duct 13 needs to be replaced, the user can rotate the cover body 20. Since the arc center of the arc plug rod 403 is coaxially arranged with the central axis of the pin shaft 21, the cover body 20 will drive the arc tube 17 to rotate when rotating, and the arc tube 17 will drive the arc plug rod 403 below to disengage from the slot 402 when rotating. At this time, the filter structure in the purification air duct 13 can be replaced. After the arc plug rod 403 is separated from the cross beam 301, the magnetic force of the magnetic block 401 attracts the cross beam 301 to achieve support for the cross beam 301, avoiding the situation that the arc plug rod 403 cannot be normally inserted into the slot 402 after the cover body 20 is buckled due to the rotational connection between the cross beam 301 and the telescopic cylinder 302. The filter structure in the purification air duct 13 is conveniently replaced, which is convenient for the user to operate.

[0028] In this embodiment, a baffle 18 is attached to one end of the arc tube 17 away from the first fan 16, and the baffle 18 is used to close the end surface of the arc tube 17. In the purification mode, air does not pass through the arc tube 17. A driving mechanism 5 is provided on the cover 20. The driving mechanism 5 includes a mounting plate 501, a shaft 502 and a first motor 503. The mounting plate 501 is connected to the arc tube 17, the mounting plate 501 is connected to the shaft 502, and the shaft 502 is rotatably connected to the cover 20.

[0029] When controlling the movement of the arc tube 17, the user can manually rotate the baffle 18 to drive the arc tube 17 to move, thereby switching the fan mode. The shaft 502 is provided to ensure the stability of the arc tube 17 during rotation.

[0030] In this embodiment, the shaft 502 is connected to the output end of the first motor 503 . The first motor 503 is a servo motor, and the stroke can be controlled by the microprocessor 9 .

[0031] In actual use, the user can start the first motor 503. After starting, the first motor 503 can drive the shaft 502 to rotate, and the shaft 502 can drive the mounting plate 501 to rotate synchronously. The mounting plate 501 drives the arc tube 17 to rotate during the rotation process. The arc tube 17 is opened by driving the first motor 503, which is convenient for the user to switch between the purification mode and the fan mode. At the same time, the position of the arc tube 17 is controlled by relying on the rotation stroke of the first motor 503. The user can send a signal to the microprocessor 9 through the terminal device to control the first motor 503 to drive the arc tube 17 to rotate, so as to realize the switching between the fan mode and the purification mode.

[0032] In this embodiment, it also includes a first grille 11 and a second grille 12, which are processed on the housing 1, and are the air outlet and air inlet in the fresh air mode. The cylinder 10 is connected with a microprocessor 9 and a contact switch 7, which are waterproofed, and a waterproof and moisture-proof coating is coated on the surface of the microprocessor 9 and the contact switch 7, which is a polyurethane coating, to further isolate moisture intrusion and improve the durability of the components. The polyurethane coating is evenly coated and ensures that it covers all welding and exposed areas, so as to avoid rusting of the microprocessor 9 and the contact switch 7 after being eroded by water vapor, and prolong the service life of the microprocessor 9 and the contact switch 7. The contact switch 7 corresponds to the position of the connecting frame 601. When switching to the fan mode, the connecting frame 601 contacts the contact switch 7 driven by the back plate 304. The contact switch 7 is connected to the digital input pin of the microprocessor 9 as an input signal source. The first fan 16 and the second fan 15 are connected to the output pin of the microprocessor 9. The start and operation of the first fan 16 and the second fan 15 are controlled by the relay, wherein the microprocessor 9 serves as a control center, receives the signal of the contact switch 7, and controls the start mode of the first fan 16 and the second fan 15 according to the preset logic. The first closing mechanism 6 is arranged in the housing 1, and the first closing mechanism 6 includes a connecting frame 601, a moving block 602, a first guide groove 603, a first roller 605, a bracket 606, and a first baffle 604. The connecting frame 601 is connected to the moving block 602. The first guide groove 603 is processed on the moving block 602. The first guide groove 603 is slidably connected with the first roller 605. The first guide groove 603 is inclined. The height of the first guide groove 603 near the rotating shaft 22 is higher than the height of the side away from the rotating shaft 22. This arrangement enables the moving block 602 to drive the first roller 605 and the bracket 606 to move upward when moving in the direction away from the rotating shaft 22. The first roller 605 is rotatably connected with the bracket 606. The first roller 605 that can rotate relative to the bracket 606 can roll in the first guide groove 603. The interior of the first guide groove 603 is an arc surface to avoid the first guide groove 603 and the first roller 605 from getting stuck. The bracket 606 is connected with the first baffle 604. The first baffle 604 fits with the inner wall of the housing 1. The first baffle 604 fits with the interior of the housing 1 to achieve position limiting, so that the first baffle 604 and the bracket 606 can only move up and down. The first baffle 604 is used to shield the first grille 11.

[0033] In actual use, when the connecting frame 601 contacts the contact switch 7, the microprocessor 9 sets a timer module inside the microprocessor 9 at the software level, and the timer can be set to 1800 seconds. When the timer overflows, the start signal of the second fan 15 is triggered. The microprocessor 9 receives the touch signal sent by the contact switch 7, starts the first fan 16, and makes the first fan 16 work continuously. The whole system controls the continuous operation of the first fan 16 through the contact switch 7, and after the contact switch 7 is touched, the second fan 15 controls the periodic start and stop of the second fan 15 through the timer module in the microprocessor 9. The connecting frame 601 will also drive the moving block 602 to move during the movement, and the moving block 602 will drive the first roller 605 to move along the first guide groove 603 during the movement. Since the first guide groove 603 is higher in the direction close to the rotating shaft 22 than in the direction away from the rotating shaft 22, the first baffle 604 is driven upward to block the first grille 11 under the traction of the first guide groove 603. At this time, in the fan mode, air can only pass through the arc tube 17. When the arc tube 17 is reset, the first baffle 604 is driven downward to no longer block the first grille 11 under the traction of the first guide groove 603. At this time, the switching of the purification mode is realized, and the first grille 11 and the second grille 12 are used to discharge and inhale the purified air. When the air diffuses from all sides, it can cover the entire room, avoiding the air gathering in a certain area and causing poor purification effect in the local area. The overall circulation of indoor air is accelerated, thereby improving the working efficiency of the purifier.

[0034] In this embodiment, shielding sheets 19 are attached to both end surfaces of the rotating shaft 22 , and the two shielding sheets 19 are connected to the two end surfaces of the cylinder 10 .

[0035] In actual use, the shielding piece 19 is used to shield the fan duct 14 or the purification duct 13 that is not located at the center of the cylinder 10. When the purification mode or the fan mode is in progress, the duct that is not involved in the work is closed to prevent external impurities from entering the fan duct 14 or the purification duct 13.

[0036] In this embodiment, a purification mechanism 2 is disposed inside the housing 1. The purification mechanism 2 includes a box body 201, a cover 204, a plurality of through slots 202, and a plurality of vents 203. The box body 201 is connected to the shielding sheet 19, the cover 204 is buckled on the box body 201, a plurality of vents 203 are processed on the cover 204, a plurality of through slots 202 are processed on the box body 201, and the interior of the box body 201 is used to place solid aromatherapy.

[0037] In actual use, the user can open the cover 204, place the solid aromatherapy in the box body 201, and then snap the cover 204 back on the box body 201. In this way, when the fan mode or the fresh air mode is in effect, the air passes through the solid aromatherapy, which accelerates the volatilization of the solid aromatherapy. The solid aromatherapy can play a role in refreshing the air. The vent holes 203 set on the cover 204 and the through slots 202 set on the box body 201 do not affect the airflow, thereby improving the air purification effect.

[0038] In this embodiment, an auxiliary mechanism 8 is provided inside the fan duct 14 and the purification duct 13. The auxiliary mechanism 8 includes a first shell 801, three filters 804, and a frame 812. The first shell 801 is connected to the purification duct 13, and the first shell 801 is detachably connected to the frame 812. The frame 812 is connected to the three filters 804. The first battery 803 is connected to the frame 812, and the first battery 803 can power the ultraviolet lamp 802, and the ultraviolet lamp 802 is connected to the frame 812.
