The first embodiment is as follows: as shown with reference to figure 1 of the drawings,

the air flow channel assembly provided by the embodiment comprises a flow channel 11 and a blowing device 12, wherein the flow channel 11 comprises a first flow channel 13 and a second flow channel 14, the first flow channel 13 and the second flow channel 14 form a communicating structure, the cross-sectional area in the flow channel 11, which is perpendicular to the axis of the flow channel 11, is gradually reduced from the first flow channel 13 to the second flow channel 14, and the blowing device 12 is in communication connection with the first flow channel 13. The blowing device 12 provides power to blow air into the first flow channel 13 from the blowing device 12, because the first flow channel 13 and the second flow channel 14 form a communicating structure, the air is blown out through the second flow channel 14 through the first flow channel 13, the cross-sectional area perpendicular to the axis of the flow channel 11 in the flow channel 11 is gradually reduced from the first flow channel 13 to the second flow channel 14, the air enters a smaller space from a larger space, the air flow is accelerated gradually, the air flow rate of the second flow channel 14 is increased, when negative ions pass through the flow channel 11, the acceleration of the flow channel 11 can be realized, the negative ions can be diffused to a farther range in the air, the action range of the purifier is enlarged, and the effect is better.

In a preferred embodiment, in addition to the above embodiment, the cross-sectional shape of the flow channel 11 perpendicular to the axis of the flow channel 11 is circular. When the blowing device 12 blows air into the first flow channel 13, the first flow channel 13 and the second flow channel 14 are circular in cross section, so that the blown air can be uniformly blown out from the second flow channel 14, transition in the flow channel 11 is smooth and has no dead angle, and the condition that dust is accumulated at the dead angle and is difficult to clean due to long service time of the flow channel 11 is avoided.

In a preferred embodiment, in addition to the above-described embodiment, the flow path 11 has an axisymmetric structure. When the blowing device 12 blows air into the flow channel 11, the air flowing space is from large to small, and the air flowing space is of a symmetrical structure along with the space in the flow channel 11, so that the air flow rates on two sides of the axis are the same, and the air and the negative ions at each position in the flow channel 11 can flow out of the air purifier with acceleration along with the negative ions passing through the flow channel 11 and enter the external environment, and the air and the negative ions at each position in the flow channel 11 can flow out of the air purifier with acceleration, so that the effect of the air purifier is better.

In a preferred embodiment, in addition to the above-described aspect, the slope of the first flow channel 13 is smaller than the slope of the second flow channel 14. Air enters the first flow channel 13 from the blowing device 12, the cross-sectional area in the first flow channel 13 is gradually reduced, so that the air is gradually accelerated, and when the air enters the second flow channel 14 from the first flow channel 13, the probability of the side wall of the second flow channel 14 contacting with negative ions is reduced because the slope of the first flow channel 13 is smaller than that of the second flow channel 14; if the slope of the second flow channel 14 is greater than the slope of the first flow channel 13, the probability of the negative ions contacting the sidewall of the second flow channel 14 is greatly increased, so that the negative ions and the dust particles are combined and attached to the second flow channel 14, which results in the accumulation of dust in the second flow channel 14 and the decrease of the density of the negative ions discharged out of the air cleaner.

In a preferred embodiment, in addition to the above-described embodiment, the inner surface of the flow channel 11 is smooth. The smooth inner surface of the flow channel 11 enables air passing through the flow channel 11 to be smoother, prevents the inner surface of the flow channel 11 from being rough and increasing air circulation resistance, enables the air to pass through the flow channel 11 more quickly, reduces dust accumulation in the flow channel 11 due to the smooth inner surface, and enables the flow channel 11 to be kept clean as far as possible in the using process.

Example two: as shown with reference to figure 2 of the drawings,

the difference between this embodiment and the first embodiment is: the runner 11 is provided with at least one through hole 15, the through hole 15 is connected with a release module 17 of a negative ion generator 16, the release module 17 is provided with a release tip 18, and the release tip 18 is placed in the runner 11. The through hole 15 is provided on the flow channel 11, so that the release module 17 extends the release tip 18 into the flow channel 11 through the through hole 15, and the release tip 18 generates negative ions, so that the negative ions are more rapidly discharged out of the air purifier along with the accelerated air.

As a preferred embodiment, further to the above, the release tip 18 is placed in the second flow channel 14. The releasing tip 18 generates negative ions, and the releasing tip 18 is placed in the second flow channel 14, so that the air is accelerated by the first flow channel 13 and then passes through the second flow channel 14 to carry the negative ions out of the air purifier, the retention time of the negative ions in the flow channel 11 is shortened, the probability of the negative ions contacting with dust particles in the flow channel 11 is also reduced, and the air purifier can remove more negative ions to purify the external environment.

In a preferred embodiment, in addition to the above-described embodiment, the height of the first flow channel 13 is larger than the height of the second flow channel 14 along the axis of the flow channel 11. The height of first runner 13 is greater than the height of second runner 14, makes the distance that air flows in first runner 13 be greater than the distance that air flows in second runner 14 to make the interior air of first runner 13 have longer time to accelerate, and the acceleration effect of its interior air of first runner 13 is good, and when air entered into second runner 14 from first runner 13, can be fast outside anion and the air that accelerates discharge air purifier, further makes the acceleration effect of runner 11 better.

In a preferred embodiment, in addition to the above, a sealing ring 19 is further disposed on the through hole 15, and the sealing ring 19 is adapted to the through hole 15 and the releasing module 17. The arrangement of the through hole 15 enables the air in the flow channel 11 to partially flow out of the through hole 15, so that the air exhausted from the flow channel 11 is reduced, the sealing ring 19 is further arranged on the through hole 15, when the releasing module 17 extends the releasing tip 18 into the flow channel 11 through the through hole 15, the arrangement of the sealing ring 19 enables the releasing module 17 at the through hole 15 to be in closer contact with the flow channel 11, the air cannot be exhausted from the through hole 15, and the acting effect of the flow channel 11 is better.

In a preferred embodiment, in addition to the above-described embodiment, a filter screen 110 is further provided in the second flow path 14. The filter screen 110 is arranged on the second flow passage 14, so that external impurities are prevented from entering the flow passage 11, and the impurities are prevented from entering to influence the normal operation of the air purifier.
