Description

Technical Field

[0001] This invention specifically relates to a dual-oscillating air purifier. Background Technology

[0002] The airflow mode of an air purifier directly affects its airflow coverage and user experience. Traditional air purifiers mostly use a single air outlet design, coupled with a fixed or unidirectional oscillating mechanism, but this has the problems of limited air delivery range and inability to dynamically adjust the airflow direction. Although some high-end products have attempted to adopt a dual air outlet structure, they usually have the following technical pain points: existing dual air outlet structures mostly only support unidirectional oscillation (such as both oscillating to the left or right at the same time), and cannot achieve reverse alternating oscillation (such as one oscillating to the left and one to the right), which limits the airflow diffusion efficiency. The fixed air outlet mode is difficult to disturb the indoor air flow, affecting the diffusion of pollutants and the purification effect, especially in a closed environment. Summary of the Invention

[0003] In view of the deficiencies of the existing technology, the technical problem to be solved by the present invention is to provide a dual-oscillating air purifier.

[0004] A dual-oscillating air purifier includes a housing with an air inlet and two first air outlets. Each first air outlet has a corresponding air outlet rotatably mounted on the housing. One end of each air outlet is equipped with a transmission gear co-centered with it. Inside the housing, drive racks are movably mounted and mesh with the transmission gears. A movable base is movably mounted inside the housing. The housing has a transmission structure that drives the two drive racks to move in the same direction or in opposite directions with the movable base. The housing also has a drive structure that drives the movable base to reciprocate.

[0005] In one embodiment, the transmission structure includes a slider, a rocker arm, a first locking member, and a second locking member. The slider is movably mounted on the housing, and the direction of movement of the slider relative to the housing is parallel to the direction of movement of the drive rack relative to the housing. The rocker arm is rotatably mounted on the slider, and first movable slots are respectively provided on both sides of the rocker arm. A first fixed shaft is provided on one side of the drive rack, and the first fixed shafts are movably mounted in the first movable slots. The direction of movement of the movable seat relative to the housing is parallel to the direction of movement of the slider relative to the housing. A second fixed shaft is provided on one side of the movable seat, and the second fixed shaft is movably mounted in one of the first movable slots. The first locking member is provided on the housing to lock the slider relative to the housing displacement. The second locking member is provided on the movable seat to lock the rocker arm relative to the slider swinging, and causes the movable seat to be connected to the slider.

[0006] In one embodiment, the first locking member includes a first electric telescopic rod disposed on the housing and a first pin disposed at the telescopic end of the first electric telescopic rod, and a first pin hole that cooperates with the first pin is provided on one side of the slider.

[0007] In one embodiment, the second locking member includes a second electric telescopic rod disposed on a movable base and a second pin disposed at the telescopic end of the second electric telescopic rod, as well as pressure plates elastically and symmetrically disposed on both sides of the slider and a transmission member for driving the two pressure plates to move closer to each other. The slider has a second pin hole that cooperates with the second pin. The transmission member includes a movable rod that is movably disposed up and down in the second pin hole, and a connecting rod is hinged between the movable rod and the pressure plate.

[0008] In one embodiment, clearance holes are provided through both sides of the swing arm, the clearance holes are located near the rotation center of the swing arm, and the second pin hole is located within the area of ​​the clearance holes.

[0009] In one embodiment, when the second pin presses against the movable rod, the rocker arm is pressed by the two pressure plates, causing the length direction of the rocker arm to be perpendicular to the length direction of the drive rack.

[0010] In one embodiment, guide shafts are provided at intervals on both sides of the slider, the pressure plate is movably sleeved on the guide shafts, and a spring is sleeved on the guide shafts between the pressure plate and the slider.

[0011] In one embodiment, the drive structure includes a motor and a drive disk disposed on the motor drive shaft. An eccentric shaft is provided on one side of the drive disk, and a second movable slot is provided on the movable seat. The eccentric shaft is movably disposed in the second movable slot.

[0012] In one embodiment, the air outlet has a second air outlet on one side, and a filter screen is provided inside the second air outlet.

[0013] In summary, the advantages of this invention over the prior art are:

[0014] This invention uses a drive structure to drive the moving seat to reciprocate, and a transmission structure to enable the two drive racks to move in the same or opposite directions, thereby controlling the synchronous or relative opposite oscillation of the two air outlets. This allows the dual air outlets to achieve oscillation in the same direction or independent relative opposite oscillation, expanding the coverage area, enhancing the air disturbance effect, and improving the purification efficiency. The reverse oscillation mode can accelerate indoor air convection and is suitable for large spaces or highly polluted environments; the same-direction mode is suitable for localized centralized purification.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 6 The present invention preferably provides a dual-oscillating air purifier, including a housing 1. The housing 1 has an air inlet 2 and a first air outlet 3 respectively. There are two first air outlets 3. An air outlet 4 is rotatably arranged on the housing 1 corresponding to the position of the first air outlet 3. A transmission gear 5 is provided at one end of the air outlet 4 and is co-centered with it. A drive rack 6 is movably arranged in the housing 1 and meshes with the transmission gear 5 respectively. A movable seat 7 is movably arranged in the housing 1. The housing 1 is provided with a transmission structure 8 that can drive the two drive racks 6 to move in the same direction or in opposite directions with the movable seat 7. The housing 1 is provided with a drive structure 9 that can drive the movable seat 7 to reciprocate.

[0023] Specifically, the drive structure drives the moving seat to reciprocate, and the transmission structure enables the two drive racks to move in the same or opposite directions, thereby controlling the synchronous or relative reverse oscillation of the two air outlets. This allows the dual air outlets to achieve oscillation in the same direction or independent relative reverse oscillation, expanding the coverage area, enhancing the air disturbance effect, and improving the purification efficiency. The reverse oscillation mode can accelerate indoor air convection and is suitable for large spaces or highly polluted environments; the same direction mode is suitable for localized centralized purification.

[0024] Further, the transmission structure 8 includes a slider 81, a rocker arm 82, a first locking member 83, and a second locking member 84. The slider 81 is movably mounted on the housing 1, and the direction of movement of the slider 81 relative to the housing 1 is parallel to the direction of movement of the drive rack 6 relative to the housing 1. The rocker arm 82 is rotatably mounted on the slider 81. First movable grooves 85 are respectively opened on both sides of the rocker arm 82. A first fixed shaft 86 is provided on one side of the drive rack 6. The first fixed shafts 86 are movably mounted in the first movable grooves 85. The direction of movement of the movable seat 7 relative to the housing 1 is parallel to the direction of movement of the slider 81 relative to the housing 1. A second fixed shaft 99 is provided on one side of the movable seat 7. The second fixed shaft 99 is movably mounted in one of the first movable grooves 85. The first locking member 83 is mounted on the housing 1 to lock the slider 81 relative to the housing 1. The second locking member 84 is mounted on the movable seat 7 to lock the rocker arm 82 relative to the slider 81 and to connect the movable seat 7 with the slider 81.

[0025] Specifically, the first locking member is used to fix the position of the locking slider, and the second locking member is in the unlocked state. When the moving seat is driven by the drive structure to move back and forth relative to the housing, the second fixed shaft on the moving seat is displaced and presses against the single-sided first movable groove of the swing rod, thereby causing the swing rod to swing back and forth relative to the slider. Then, the first movable grooves on both sides of the swing rod press against the first fixed shaft of the drive rack respectively, so that the two drive racks move in opposite directions, thereby driving the two transmission gears to rotate in the same direction, realizing that the two air outlets swing out air in the same direction.

[0026] When the two air outlets need to vent air in the same direction, the slider position is unlocked by the first locking component, and the second locking component is locked at this time to forcibly lock the relative positions of the swing rod, the slider and the moving seat. Then, when the moving seat is driven by the drive structure to reciprocate relative to the housing, the second fixed shaft on the moving seat is displaced and presses against the first movable groove on one side of the swing rod. The second fixed shaft presses against the first movable groove, so that the swing rod, the slider and the moving seat move in the same direction as a whole. At this time, the two drive racks move in the same direction, thereby driving the two transmission gears to rotate in opposite directions, so as to realize that the two air outlets swing air in opposite directions.

[0027] Furthermore, the first locking member 83 includes a first electric telescopic rod 87 disposed on the housing 1 and a first pin 88 disposed at the telescopic end of the first electric telescopic rod 87, and a first pin hole 89 is provided on one side of the slider 81 to cooperate with the first pin 88.

[0028] Specifically, the first electric telescopic rod drives the first pin to move, so as to allow the first pin to be inserted into or disengaged from the first pin hole of the slider, thereby locking or moving the slider relative to the housing.

[0029] Furthermore, the second locking member 84 includes a second electric telescopic rod 90 disposed on the movable seat 7 and a second pin 91 disposed at the telescopic end of the second electric telescopic rod 90, as well as pressure plates 92 elastically and symmetrically disposed on both sides of the slider 81 and a transmission member for driving the two pressure plates 92 to move closer to each other. The slider 81 has a second pin hole 93 that cooperates with the second pin 91. The transmission member includes a movable rod 94 that is movably disposed in the second pin hole 93. The movable rod 94 and the pressure plate 92 are hinged together by a connecting rod 95.

[0030] Specifically, the second electric telescopic rod drives the second pin to move, allowing the second pin to engage or disengage from the second pin hole of the slider. When the second pin is engaged in the second pin hole, it presses against the movable rod, causing the movable rod to move relative to the slider. Then, through the linkage transmission, the two pressure plates are driven to move closer to each other. The two pressure plates press against both sides of the swing rod, thus forcibly locking the swing rod so that its length direction is perpendicular to the length direction of the drive rack. This forcibly locks the relative positions of the swing rod, the slider, and the moving seat. The length direction of the swing rod is perpendicular to the length direction of the drive rack. When the moving seat is driven to move, the second fixed shaft moves accordingly and presses against the first movable groove of the swing rod, making the swing rod perpendicular to the drive rack and repeatedly moving along the direction of the drive rack. This drives the two drive racks to move in the same direction, and drives the two transmission gears to rotate in opposite directions, achieving the opposite rotation and swinging air output of the two air outlets.

[0031] Furthermore, clearance holes 96 are provided through both sides of the rocker arm 82. The clearance holes 96 are located near the rotation center of the rocker arm 82, and the second pin hole 93 is located within the area of ​​the clearance holes 96. Because the clearance holes are located near the rotation center of the rocker arm, the second pin hole is not obstructed by the rocker arm when the rocker arm reciprocates relative to the slider, thus facilitating the alignment and engagement of the second pin in the second locking component on the moving seat with the second pin hole. Preferably, the initial state of the rocker arm is that its length direction is perpendicular to the length direction of the drive rack, so that the reset rocker arm is in its initial state each time the drive structure stops.

[0032] Furthermore, when the second pin 91 presses against the movable rod 94, the rocker arm 82 is pressed by the two pressure plates 92, causing the length direction of the rocker arm 82 to be perpendicular to the length direction of the drive rack 6.

[0033] Furthermore, guide shafts 97 are respectively provided on both sides of the slider 81 at intervals, and the pressure plate 92 is movably sleeved on the guide shafts 97. A spring 98 is sleeved on the guide shaft 97 between the pressure plate 92 and the slider 81. Thus, through the guide shafts and the spring, the relative elastic displacement of the two pressure plates is achieved.

[0034] Furthermore, the drive structure 9 includes a motor 11 and a drive disk 12 mounted on the drive shaft of the motor 11. An eccentric shaft 13 is provided on one side of the drive disk 12, and a second movable slot 14 is provided on the movable seat 7. The eccentric shaft 13 is movably disposed within the second movable slot 14. Specifically, a single motor, in conjunction with the drive disk and eccentric shaft, drives the movable seat to reciprocate, thereby effectively reducing the number of motors, lowering costs, and improving the synchronization of the rotation of the two exhaust ducts.

[0035] Furthermore, the air outlet 4 has a second air outlet on one side, and a filter screen 15 is provided inside the second air outlet.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
