The low wind resistance port shunt mechanism 200 includes: a tapered pipe 210 fixedly connected to the port outer wall of the shell 110 near the position of the air blower, a mounting seat 211 fixed to one end of the tapered pipe 210, and an arc-shaped opening of the tapered pipe 210 designed to avoid sudden turning and collision of airflow when entering the air duct.

[0040] The low wind resistance port shunt mechanism 200 further includes: a flow guide plate 220 arranged in plurality and fixedly arranged at equal intervals inside the tapered pipe 210 at the lower position, which is fixedly arranged at equal intervals inside the tapered pipe 210 at the lower position by the flow guide plate 220, the arc-shaped shape of which matches the airflow flow characteristics, and can guide the wind to turn along the arc.

[0041] The tuyere cleaning mechanism 300 comprises a collection shell 310 detachably connected with the outer wall of the shell 110, and a plurality of trapezoidal holes 311 are equidistantly arranged on one side of the outer wall of the collection shell 310, a partition plate 312 is rotatably arranged at the port of the collection shell 310 through a rotating shaft, a coil spring 313 is fixed between the rotating shaft of the partition plate 312 and the inner wall of the port of the collection shell 310, a plurality of plug plates 320 are equidistantly fixed on the outer wall of the collection shell 310 at the side of the port, the inner part of the plug plate 320 is insertedly matched with the outer wall of the flow guide plate 220, a filter core 330 is fixed between the outer walls of two adjacent flow guide plates 220, a motor 340 is fixedly connected with the inner wall of the square shell 120, a threaded rod 341 is fixedly connected with the rotating shaft of the motor 340, one end of the threaded rod 341 is rotatably connected with the outer wall of the shell 110, a square rod one 342 is screwed on the threaded rod 341, and the outer wall of the square rod one 342 is slidably inserted with the inner wall of the square shell 120, a plurality of square rods two 343 are equidistantly fixed on the outer wall of the square rod one 342, one end of the square rod two 343 is fixedly connected with a trapezoidal rod 344, and an arc plate 345 is fixedly connected with the end of the square rod two 343 close to the trapezoidal rod 344, the outer wall of the trapezoidal rod 344 is insertedly matched with the inner part of the trapezoidal hole 311, and the outer wall of the arc plate 345 is slidably inserted with the inner part of the arc hole 111, so that the automatic cleaning of the impurities on the filter core 330 can be realized through the tuyere cleaning mechanism 300.

[0042] Specifically, during operation, in the low-resistance air conditioning duct mechanism 100, the low-resistance port diversion mechanism 200 is fixed at the air inlet port on the outer wall of the housing 110. The unique arc-shaped opening and inwardly tapering design of the tapered tube 210 allows the incoming airflow to transition smoothly, avoiding sudden turns and collisions. According to Bernoulli's principle, the airflow accelerates and the pressure decreases in the contraction channel, reducing airflow separation. The guide plates 220, which are fixed at equal intervals inside the tapered tube 210, guide the airflow along the arc to the blower and divert the incoming airflow. The diverted airflow passes through the filter element 330 between each set of insert plates 320. The diverted airflow will have uniform contact with the filter element 330. The filter element 330 is made of composite fiber material, is arc-shaped and bendable, and has low air resistance. Its outwardly expanding shape increases the contact area with the air. According to the principle of fluid continuity, when the air volume is constant, the flow area increases, the air velocity decreases, and thus the air resistance decreases. At the same time, the tilting... The slanted design allows for more even airflow, avoiding localized turbulence and further reducing wind resistance. During the filtration process, filter element 330 intercepts impurities in the airflow. When impurities accumulate on filter element 330, causing increased wind resistance, the air outlet cleaning mechanism 300 starts working. Motor 340 drives threaded rod 341 to rotate, and square rod 342, which is screwed onto threaded rod 341, slides on the inner wall of square shell 120, driving square rod 343 to move. One end of square rod 343 is fixed to trapezoidal rod 344. Squeezing the partition 312 causes it to rotate, exposing the port of the collection shell 310. The arc plate 345 moves along the surface of the filter element 330, pushing impurities into the collection shell 310 for collection. The silicone adhesive material attached to the inner wall of the collection shell 310 is used to adhere dust and prevent dust from being stirred up. After cleaning, the motor 340 reverses, the arc plate 345 returns to its original position, and the partition 312 is springed back to its original position by the coil spring 313, blocking the port of the collection shell 310.

[0043] Example 1

[0044] like Figure 2 As shown, in this embodiment, the low-resistance port diversion mechanism 200 includes: a tapered tube 210 fixedly connected to the outer wall of the housing 110 port near the blower, and a mounting base 211 fixed to one end of the tapered tube 210.

[0045] In this embodiment, the arc-shaped opening design of the tapered tube 210 avoids sudden turning and collision of airflow when entering the duct, compared with traditional right-angle or irregularly shaped inlets, reducing turbulence and vortex formation, allowing airflow to flow naturally into the duct, reducing initial wind resistance. Its inwardly tapering structure accelerates airflow and reduces separation based on Bernoulli's principle, further reducing wind resistance.

[0046] like Figure 4As shown, in this embodiment, the low-resistance port diversion mechanism 200 further includes: a plurality of guide plates 220 are provided and fixed at equal intervals inside the tapered tube 210 at the lower position.

[0047] In practice, the guide plates 220 are fixed at equal intervals inside the tapered tube 210. Their arc shape matches the airflow characteristics, guiding the air to turn along the arc and orderly directing the airflow to the blower. This avoids disordered airflow in the duct, reduces mutual interference and turbulence between airflows, and ensures that the airflow flows to the blower efficiently and stably. Furthermore, the split airflow can make uniform contact with the corresponding filter element 330, preventing excessively high local airflow velocity from forming turbulence, which would increase the friction between air molecules and the filter element 330, not only increasing wind resistance but also reducing the filtration effect of the filter element 330.

[0048] Example 2

[0049] like Figures 3-5 As shown, in this embodiment, the air vent cleaning mechanism 300 includes: a collection shell 310 detachably connected to the outer wall of the housing 110, with a plurality of trapezoidal holes 311 evenly spaced on one side of its outer wall; a partition plate 312 rotating at the port of the collection shell 310 via a rotating shaft; a coil spring 313 fixed between the rotating shaft of the partition plate 312 and the inner wall of the port of the collection shell 310; a plurality of insert plates 320 evenly spaced and fixed to the outer wall of the collection shell 310 on one side of the port, with the insert plates 320 internally engaging with the outer wall of the guide plate 220; a filter element 330 fixed between the outer walls of two adjacent guide plates 220; and a motor 340 connected to the square housing 110. The inner wall of the 0 is fixedly connected, and the shaft of the motor 340 is fixedly connected to a threaded rod 341. One end of the threaded rod 341 is rotatably connected to the outer wall of the housing 110. The square rod 342 is screwed onto the threaded rod 341, and its outer wall is slidably inserted into the inner wall of the square housing 120. Several square rods 343 are provided and fixed at equal intervals on the outer wall of the square rod 342. One end of the square rod 343 is fixedly connected to a trapezoidal rod 344, and an arc plate 345 is fixedly connected to one end of the square rod 343 near the position of the trapezoidal rod 344. The outer wall of the trapezoidal rod 344 is inserted into the trapezoidal hole 311, and the outer wall of the arc plate 345 is slidably inserted into the arc hole 111.

[0050] In specific implementation, the wind port cleaning mechanism 300 can automatically clean the impurities on the filter element 330, when the wind resistance of the filter element 330 is increased due to the accumulation of impurities, the wind port cleaning mechanism 300 is started, without manual cleaning of the filter element 330, saving manpower and improving cleaning efficiency, and the silica gel adhesive material pasted on the inner wall of the collection shell 310 can effectively adsorb dust, preventing dust from flying during cleaning. In addition, the detachable connection of the collection shell 310 and the design of the plugboard 320 and the filter element 330 make the filter element 330 easy to disassemble and replace, when the filter element 330 reaches the service life or the filtering effect decreases, the user can easily maintain daily, ensuring the continuous and efficient operation of the air duct system.
