Description

Technical Field

[0001] The present invention particularly relates to a double-shaking air purifier with air outlet. Background Art

[0002] The air outlet mode of an air purifier directly affects its air flow coverage and user experience. Most traditional air purifiers adopt a single air outlet design, combined with a fixed or one-way swing mechanism, but there are problems such as limited air supply range and inability to dynamically adjust the air flow direction. Although some high-end products attempt to adopt a double air outlet structure, there are usually the following technical pain points: Most existing double air outlet structures only support swinging in the same direction (such as swinging left or right at the same time), and cannot achieve reverse alternating swinging (such as one swinging left and the other swinging right), which limits the air flow diffusion efficiency. The fixed air outlet mode is difficult to disturb the indoor air flow, affecting the diffusion and purification effect of pollutants, especially more obvious in a closed environment.

[0021] The present invention will be further described below in conjunction with the accompanying drawings and detailed implementation manners:

[0022] As Figures 1 to 6 shown, the embodiment of the present invention preferably provides a double-shaking air outlet air purifier, including a housing 1, an air inlet 2 and a first air outlet 3 are respectively opened on the housing 1, there are two first air outlets 3, air outlet cylinders 4 are respectively rotatably arranged on the housing 1 corresponding to the positions of the first air outlets 3, a transmission gear 5 concentric with one end of the air outlet cylinder 4 is provided, drive racks 6 respectively meshed with the transmission gears 5 are movably arranged in the housing 1, a moving seat 7 is movably arranged in the housing 1, a transmission structure 8 capable of driving the two drive racks 6 to move in the same direction or move relatively in the opposite direction along with the movement of the moving seat 7 is provided on the housing 1, and a driving structure 9 capable of driving the moving seat 7 to reciprocate is provided on the housing 1.

[0023] Specifically, the driving structure drives the moving seat to reciprocate, and then the transmission structure is used to realize the same-direction or opposite-direction movement of the two drive racks, so as to control the synchronous shaking or relative reverse shaking of the two air outlet cylinders, so that the double air outlet cylinders can realize the same-direction shaking or independent relative reverse shaking, expand the coverage range, enhance the air disturbance effect, improve the purification efficiency, and the reverse shaking mode can accelerate the indoor air convection, which is suitable for large spaces or high-pollution environments; the same-direction mode is suitable for local centralized purification.

[0024] Further, the transmission structure 8 includes a slider 81, a swing rod 82, a first locking member 83 and a second locking member 84. The slider 81 is movably arranged on the housing 1, and the moving direction of the slider 81 relative to the housing 1 is parallel to the moving direction of the driving rack 6 relative to the housing 1. The swing rod 82 is rotatably arranged on the slider 81. First moving grooves 85 are respectively formed on both sides of the swing rod 82. A first fixed shaft 86 is arranged on one side of the driving rack 6, and the first fixed shafts 86 are movably arranged in the first moving grooves 85 in a one-to-one correspondence. The moving direction of the moving seat 7 relative to the housing 1 is parallel to the moving direction of the slider 81 relative to the housing 1. A second fixed shaft 99 is arranged on one side of the moving seat 7, and the second fixed shaft 99 is movably arranged in one of the first moving grooves 85. The first locking member 83 is arranged on the housing 1 and can lock the displacement of the slider 81 relative to the housing 1. The second locking member 84 is arranged on the moving seat 7 and can lock the swing of the swing rod 82 relative to the slider 81, and cause the moving seat 7 to be connected to the slider 81.

[0025] Specifically, the first locking member is used to fixedly lock the position of the slider. At this time, the second locking member is in an unlocked state. When the moving seat is driven by the driving structure to reciprocate relative to the housing, the second fixed shaft on the moving seat is displaced accordingly and presses against the unilateral first moving groove of the swing rod, thereby causing the swing rod to reciprocally swing relative to the slider. Then, the first moving grooves on both sides of the swing rod respectively press against the first fixed shafts of the driving rack in a one-to-one correspondence, so as to cause the two driving racks to move in opposite directions relative to each other, thereby driving the two transmission gears to rotate in the same direction, and realizing the same-direction swinging air outlet of the two air outlets.

[0026] When the two air outlets need to blow air in the same direction, the position of the slider is unlocked by the first locking member. At this time, the second locking member is in a locked state to forcibly lock the relative positions among the swing rod, the slider and the moving seat. Then, when the moving seat is driven by the driving structure to reciprocate relative to the housing, the second fixed shaft on the moving seat is displaced accordingly and presses against the unilateral first moving groove of the swing rod. Then, by pressing the second fixed shaft in the first moving groove, the swing rod, the slider and the moving seat as a whole move in the same direction. At this time, the two driving racks move in the same direction, thereby driving the two transmission gears to rotate in opposite directions relative to each other, and realizing the reverse swinging air outlet of the two air outlets relative to each other.

[0027] Further, the first locking member 83 includes a first electric telescopic rod 87 arranged on the housing 1 and a first bolt 88 arranged at the telescopic end of the first electric telescopic rod 87. A first pin hole 89 matched with the first bolt 88 is arranged on one side of the slider 81.

[0028] Specifically, the first electric telescopic rod is used to drive the displacement of the first bolt, so as to realize the insertion or detachment of the first bolt into or from the first pin hole of the slider, and realize the locking or movement of the slider relative to the housing.

[0029] Furthermore, the second locking member 84 includes a second electric telescopic rod 90 disposed on the moving seat 7, a second bolt 91 disposed at the telescopic end of the second electric telescopic rod 90, and pressing plates 92 symmetrically and elastically movably disposed on both sides of the slider 81 and a transmission member for driving the two pressing plates 92 to move relatively closer; a second pin hole 93 engaged with the second bolt 91 penetrates through the slider 81; wherein, the transmission member includes a movable rod 94 movably disposed up and down in the second pin hole 93, and a connecting rod 95 is hinged between the movable rod 94 and the pressing plate 92.

[0030] Specifically, the second electric telescopic rod is used to drive the second bolt to displace, so as to realize the insertion or detachment of the second bolt into or from the second pin hole of the slider. When the second bolt is inserted into the second pin hole, the second bolt can press against the movable rod to force the movable rod to displace relative to the slider, and then through the transmission of the connecting rod, the two pressing plates are driven to move relatively closer. The two pressing plates respectively press against both sides of the swing rod, so as to forcibly lock the swing rod so that the length direction of the swing rod is perpendicular to the length direction of the driving rack, realizing the forced locking of the relative positions among the swing rod, the slider and the moving seat. And the length direction of the swing rod is perpendicular to the length direction of the driving rack. Then, when the moving seat is driven to displace, the second fixed shaft can displace along with it and press against the first movable groove of the swing rod, realizing that the swing rod is perpendicular to the driving rack and repeatedly displaces along the moving direction of the driving rack, so as to drive the two driving racks to displace in the same direction, and drive the two transmission gears to rotate in opposite directions relatively, realizing the reverse rotation and swinging air outlet of the two air outlet cylinders.

[0031] Furthermore, through holes 96 are respectively formed through both sides of the swing rod 82, the through holes 96 are located near the rotation center of the swing rod 82, and the second pin hole 93 is located within the range of the through holes 96. Further, because the through holes are near the rotation center of the swing rod, when the swing rod swings reciprocally relative to the slider, the second pin hole will not be covered by the swing rod due to the action of the through holes, which is convenient for the second bolt in the second locking member on the moving seat to be aligned and engaged with the second pin hole. Preferably, the initial state of the swing rod is defaulted to be that the length direction is perpendicular to the length direction of the driving rack. Then, every time the driving structure stops, its reset swing rod is in the initial state.

[0032] Furthermore, when the second bolt 91 presses against the movable rod 94, the swing rod 82 is pressed by the two pressing plates 92 so that the length direction of the swing rod 82 is perpendicular to the length direction of the driving rack 6.

[0033] Furthermore, guide shafts 97 are respectively and spacedly disposed on both sides of the slider 81, the pressing plates 92 are movably sleeved on the guide shafts 97, and springs 98 are sleeved on the guide shafts 97 between the pressing plates 92 and the slider 81. Further, through the guide shafts and the springs, the relative elastic away displacement of the two pressing plates is realized.

[0034] Further, the driving structure 9 includes a motor 11 and a driving disc 12 arranged on the driving shaft of the motor 11. An eccentric shaft 13 is provided on one side of the driving disc 12. A second moving groove 14 is formed in the moving seat 7, and the eccentric shaft 13 is movably arranged in the second moving groove 14. Specifically, a single motor is used in cooperation with the driving disc and the eccentric shaft to drive the moving seat to make reciprocating displacement, thereby effectively reducing the number of motors, lowering the cost and improving the synchronization of the rotation of the two air outlet cylinders.

[0035] Further, one side of the air outlet cylinder 4 has a second air outlet, and a filter screen 15 is arranged in the second air outlet.
