Specific embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Below with reference to the accompanying drawings and in conjunction with the embodiments describing the present invention in detail.
Referring to shown in Fig. 1 and Fig. 2, the air channel structure of the present embodiment includes that air channel housing 10, air channel barrier 20, first are elastic
The elastic sealing element 40 of sealing member 30 and second.Air channel housing 10 has the first air outlet 11 and the second air outlet 12.Air channel barrier
20 inside for being located at air channel housing 10, air channel barrier 20 has the first occlusion state for blocking the first air outlet 11 and blocks second
Second occlusion state of air outlet 12.First elastic sealing element 30 is arranged on the inner surface 13 of air channel housing 10, and first is elastic
Sealing member 30 has the first naturalness and the first compressive state compressed by the pressure of air channel barrier 20, when air channel gear
When plate 20 is in the first occlusion state, the inner surface 34 of the first elastic sealing element 30 contacts with the outer surface 21 of air channel barrier 20
And the first elastic sealing element 30 blocks the gap between the outer surface 21 of air channel barrier 20 and the inner surface 13 of air channel housing 10.
Second elastic sealing element 40 is arranged on the inner surface 13 of air channel housing 10, and the second elastic sealing element 40 has the second nature state
The second compressive state compressed with the pressure for being subject to air channel barrier 20, when air channel barrier 20 is in the second occlusion state,

Gap between the outer surface 21 and the inner surface 13 of air channel housing 10 of gear air channel barrier 20.If the first elastic sealing element 30
When a part for inner surface 34 contacts with a part for the outer surface 21 of air channel barrier 20, you can referred to as the first elastic sealing element
30 inner surface 34 contacts with the outer surface 21 of air channel barrier 20.Described " inner surface " and " outer surface " is relative in text
For the center of air channel structure.
Using the air channel structure of the present embodiment, due to being provided with the first elastic sealing element 30 and the second elastic sealing element 40,
When air channel barrier 20 is in the first occlusion state, the inner surface 34 of the first elastic sealing element 30 and the outer surface of air channel barrier 20
21 contact and the first elastic sealing element 30 block the outer surface 21 of air channel barrier 20 and air channel housing 10 inner surface 13 it
Between gap, therefore, the gap that gas will not be between the outer surface 21 of Jing air channel barriers 20 and the inner surface 13 of air channel housing 10
Flow out air channel housing 10, it is to avoid gas is leaked.When air channel barrier 20 is in the second occlusion state, the second elastic sealing element 40
Inner surface 44 contacts with the outer surface 21 of air channel barrier 20 and the second elastic sealing element 40 blocks the appearance of air channel barrier 20
Gap between the inner surface 13 of face 21 and air channel housing 10, therefore, gas will not Jing air channel barriers 20 outer surface 21 and wind
Flow out air channel barrier 20 for gap between the inner surface 13 of road housing 10, therefore, gas equally will not Jing air channel barriers 20 it is outer
Flow out air channel housing 10 in gap between the inner surface 13 of surface 21 and air channel housing 10, it is to avoid gas is leaked.Again due to first
Elastic sealing element 30 has the pressure by air channel barrier 20 and the first compressive state for being compressed, thus when air channel barrier 20 by
When first occlusion state is to the second occlusion state transition, the first elastic sealing element 30 can be compressed and air channel barrier 20 is allowed
Position, so that air channel barrier 20 is smoothly converted to the second occlusion state.In the same manner, it is subject to air channel because the second elastic sealing element 40 has
The pressure of baffle plate 20 and the second compressive state for being compressed, therefore when air channel barrier 20 blocks shape from the second occlusion state to first
During state transition, the second elastic sealing element 40 can be compressed and air channel barrier 20 is stepped down (referring to Fig. 2), so as to air channel barrier
20 are smoothly converted to the first occlusion state.As the above analysis, the air channel structure of the present embodiment can avoid leaking out, Jin Erti
High heat exchange efficiency.
Referring to shown in Fig. 1 and Fig. 2, in the present embodiment, when air channel barrier 20 is in the first occlusion state, air channel barrier
20 contact with the second elastic sealing element 40 and inner surface 44 and the air channel barrier 20 of the second elastic sealing element 40 inner surface
22 and the inner surface 13 of air channel housing 10 seamlessly transit；When air channel barrier 20 is in the second occlusion state, air channel barrier
20 contact with the first elastic sealing element 30 and inner surface 34 and the air channel barrier 20 of the first elastic sealing element 30 inner surface
22 and the inner surface 13 of air channel housing 10 seamlessly transit.Using said structure, air channel barrier 20 can be made elastic with first
Step is avoided the occurrence of between the elastic sealing element 40 of sealing member 30 or second, it is to avoid the integrity in destruction air channel, further increase
Heat exchange efficiency.

12 extend the first extensions, the gap between the first extension and the inner surface 13 of air channel housing 10 by the first fixed part extremely
Gradually increase on the direction of the first air outlet 11.When the first flexure strip 31 is subject to the pressure of air channel barrier 20, the first flexure strip
31 move with the first compressive state towards the inner surface 13 of air channel housing 10, and air channel barrier 20 is stepped down.First
The inner surface 34 of elastic sealing element 30 is formed in the first flexure strip 31 and is formed on the first flexure strip 31.
Shown in Figure 1, in the present embodiment, the first elastic sealing element 30 also includes the first catch 32, the first catch 32
Angle is formed with the first flexure strip 31 and extended towards the first air outlet 11, when air channel barrier 20 is in the second occlusion state
When, the first catch 32 is supported on air channel barrier 20.Using said structure, the first catch 32 can play limit to air channel barrier 20
Position effect, makes air channel barrier 20 be maintained at the second occlusion state, and is easier to make the inner surface 34 of the first elastic sealing element 30
Formed with the inner surface 22 of air channel barrier 20 and seamlessly transitted.Furthermore it is possible to further avoid the appearance of gas Jing air channel barriers 20
Flow out in gap between the inner surface 13 of face 21 and air channel housing 10.Certainly, if the first fixed part is interior with air channel housing 10
The connection on surface 13 can avoid what the gap between the first flexure strips of gas Jing 31 and the inner surface 13 of air channel housing 10 was flowed out
Words, can be not provided with the first catch 32.
