[0041] ​​The air outlet adjusting assembly 8 comprises a second cavity 801, a circular frame 803 arranged inside the second cavity 801, a third cavity formed in the circular frame 803, a first motor 804 fixedly connected to the two sides of the top of the third cavity, a first rotating shaft 805 fixedly connected to one end of the output shaft of the first motor 804, an eccentric wheel 806 fixedly connected to the first rotating shaft 805, the eccentric wheel 806 being rotatably connected inside the circular frame 803, a sliding plate 807 arranged on the other side of the eccentric wheel 806, the sliding plate 807 being slidably connected inside the second cavity 801, a rack 809 fixedly connected to the side, away from the eccentric wheel 806, of the sliding plate 807, a first gear 810 meshedly connected to the other side of the rack 809, a connecting shaft 811 fixedly connected inside the first gear 810, the connecting shaft 811 being rotatably connected inside the top seat 2, a blade 812 fixedly connected to the other end of the connecting shaft 811 and extending into the air outlet 802, a spring 808 arranged above the rack 809 and fixedly connected to the inner walls of the sliding plate 807 and the top seat 2, the second cavity 801 and the air outlet 802 being both located inside the top seat 2, the two air outlets 802 being symmetrically arranged on the two sides of the second cavity 801, a second rotating shaft 9 fixedly connected to the top of the circular frame 803, a fan blade 10 fixedly connected to the top end of the second rotating shaft 9 and extending into the fixed box 3, the second rotating shaft 9 being rotatably connected inside the top seat 2 and the fixed box 3, a second gear 11 fixedly connected to the outer circumferential side of the second rotating shaft 9 and arranged below the fan blade 10, a third gear 12 meshedly connected to one side of the second gear 11, a third rotating shaft 13 fixedly connected inside the third gear 12, a second motor 14 fixedly connected to the bottom end of the third rotating shaft 13, the second motor 14 being fixedly connected to the inner wall of the fixed box 3 at the bottom, the fixed box 3 being fixedly connected to the top side of the outer portion of the cabin 1 at the bottom, the top side of the inner portion of the cabin 1 being symmetrically provided with a first through hole, a connecting box 5 being arranged in the first through hole, the connecting box 5 being in communication with the fixed box 3 at the top and in communication with the air outlet 802 at the bottom, and the cabin 1 being provided with air outlets at the bottom on both sides.

[0042] Detailed Implementation: Place the chamber 1 in a suitable location. Start the second motor 14 as needed. The second motor 14 drives the third shaft 13 and the third gear 12 to rotate. Utilizing the linkage effect between the third gear 12 and the second gear 11, power is transmitted to the second gear 11, causing the second gear 11 to drive the second shaft 9 and the fan blade 10 to rotate. The fan blade 10 delivers outside air to the fixed box 3 and the interior of the chamber 1 to ensure the air quality inside the chamber 1. The filter 4 filters the air entering the fixed box 3 and the interior of the chamber 1. Filtering is performed to prevent dust and impurities from the outside air from entering the fixed box 3 and the cabin 1, thus preventing any impact on the air quality inside the cabin 1. Simultaneously, the second rotating shaft 9 drives the circular frame 803 to rotate. During this rotation, the circular frame 803 drives the first motor 804, the first rotating shaft 805, and the eccentric wheel 806 inside it to rotate. The eccentric wheel 806 continuously compresses the sliding plate 807 and the spring 808 during rotation. Utilizing the linkage effect between the sliding plate 807 and the rack 809, power is transmitted... The power is passed to the rack 809, causing it to move linearly. Then, utilizing the linkage between the rack 809 and multiple first gears 810, power is transmitted to the first gears 810, causing them to drive the connecting shaft 811 and the blades 812 to rotate. This adjusts the angle of the blades 812, thereby adjusting the air outlet angle and direction at the air outlet 802, ensuring even distribution of gas into the cabin 1 and effectively guaranteeing the overall air quality inside the cabin 1. The first motor 804 is then activated as needed. The first motor 804 drives the first rotating shaft 805 to rotate. Utilizing the linkage effect between the rack 809 and the eccentric wheel 806, power is transmitted to the eccentric wheel 806. The operating angle of the eccentric wheel 806 extending out of the circular frame 803 is adjusted to adjust the operating position of the sliding plate 807 and the rack 809. This, in turn, adjusts the operating angle range of the first gear 810 and the blade 812, thereby adjusting the air outlet angle and operating range at the air outlet 802, further improving the applicability of the equipment during use.

[0043] The noise reduction component 7 includes an arc-shaped block 701, which is disposed inside the connecting box 5 and is fixedly connected inside the connecting box 5. Multiple air holes 702 are opened inside the arc-shaped block 701. A negative ion generator is provided on the top side of the arc-shaped block 701, and an ultraviolet lamp is provided on the bottom side of the arc-shaped block 701. Both the negative ion generator and the ultraviolet lamp are fixedly connected to the inner wall of the connecting box 5.

[0044] Specifically, the filtered gas enters the connecting box 5, the negative ion generator adds negative oxygen ions to the air in the connecting box 5, and the ultraviolet lamp sterilizes the air to ensure the quality of the air in the cabin 1 and the comfort of the user. The arc-shaped block 701 and the air holes 702 consume the air flow in the connecting box 5, which reduces the flow rate of the air flow, reduces the impact of the air flow on the inner walls of the connecting box 5 and the top seat 2, reduces the noise caused by the vibration of the inner walls of the device, and reduces the noise caused by friction during the flow of the air flow. The device purifies the air in the cabin 1 while improving the quietness in the cabin 1. The material of the arc-shaped block 701 can be selected according to actual needs.

[0045] The mounting assembly 6 includes a first cavity 601 located inside the fixed box 3. A lead screw 602 is arranged on one side of the first cavity 601 and rotatably connected to the inside of the fixed box 3. One end of the lead screw 602 extends to the outside of the fixed box 3 and is fixedly connected with a handle 603. Threaded sleeves 604 are threadedly connected to both sides of the lead screw 602. A connecting plate 605 is fixedly connected to one side of the threaded sleeves 604 and slidably connected to the inside of the first cavity 601. First clamping blocks 606 are fixedly connected to opposite sides of the two connecting plates 605. Second clamping blocks 607 are arranged on the other sides of the first clamping blocks 606. Rectangular through holes are formed in the second clamping blocks 607 and are clamped with the first clamping blocks 606. The filter screen 4 is fixedly connected to the top of the first clamping blocks 606 and arranged on the top of the fixed box 3 and the fan blade 10.

[0046] Specifically, after long-term use, the handle 603 is manually operated to drive the lead screw 602 to rotate. The lead screw 602 and the two threaded sleeves 604 are connected to each other, and power is transmitted to the two threaded sleeves 604, which drives the connecting plates 605 and the first clamping blocks 606 to move away from each other. As the first clamping blocks 606 move away, the first clamping blocks 606 gradually move away from the rectangular through holes in the second clamping blocks 607, which releases the fixing effect of the first clamping blocks 606 on the second clamping blocks 607. This allows the filter screen 4 to be quickly disassembled, cleaned, and assembled, thereby ensuring the overall use effect of the device.
