By the translation of the switching plate, the internal blowing mode and the internal suction mode can be switched, which can realize the blowing or suction of the ventilation system and improve its applicability.

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] Please refer to the following: Figures 1-5As shown, a translational blowing and suction integrated device is provided, including a fan 1 and a switching plate 6. The fan 1 is provided with a suction channel 16 and a blowing channel 17. The suction channel 16 is provided with an inner suction port 2 and an outer suction port 4. The blowing channel 17 is provided with an inner blowing port 3 and an outer blowing port 5. The inner suction port 2 and the inner blowing port 3 are connected to a ventilation system 18, and the outer suction port 4 and the outer blowing port 5 are connected to the external environment. The switching plate 6 is translatably disposed within the suction channel 16 and the blowing channel 17 to realize the switching between an internal blowing mode when the inner blowing port 3 and the outer suction port 4 are open, and an internal suction mode when the inner suction port 2 and the outer blowing port 5 are open. The principle of the device is as follows: the internal blowing mode and the internal suction mode can be switched by the translation of the switching plate 6. In the internal blowing mode, the fan 1 draws in air from the external air intake 4, accelerates the air, and then discharges it from the internal blowing vent 3. In the internal suction mode, the fan 1 draws in air from the internal air intake vent 2, accelerates the air, and then discharges it from the external air intake vent 5. Users can adjust the position of the switching plate 6 according to their own needs to switch between internal blowing mode and internal suction mode. When applied to seats, it can realize the switching between seat blowing and suction, improving the seat's adaptability. When the seat with the translational blowing and suction integrated device is applied to the vehicle, it can improve the driving and riding experience.

[0037] In this embodiment, the four air vents and the switching plate 6 are specifically arranged as follows: the suction channel 16 is located on one side of the blowing channel 17, which can be on the left and right sides or on the top and bottom sides. The inner blowing vent 3 and the inner suction vent 2 are arranged on the same side. In this embodiment, the inner blowing vent 3 and the inner suction vent 2 are respectively located at the ends of the blowing channel 17 and the suction channel 16. The switching plate 6 is a bent plate structure with a U-shaped protrusion in the middle. The outer blowing vent 5 and the outer suction vent 4 are respectively located on both sides of the support arm of the U-shaped protrusion in the middle of the switching plate 6. A third through hole 7 is provided at the bottom arm of the U-shaped protrusion in the middle of the switching plate 6. The translation direction of the switching plate 6 is parallel to the orientation of the outer blowing vent 5 and the outer suction vent 4. The switching plate 6 is translated to realize that the third through hole 7 is in the blowing channel. The switching between channel 17 and suction channel 16 involves two U-shaped protrusions in the middle of the switching plate 6. These protrusions are used to block the external air outlet 5 or the external air intake 4 after the third through hole 7 is switched. In other words, the switching plate 6 has two positions for switching adjustment. In the first position, the third through hole 7 is located in the air outlet 17. One of the U-shaped protrusions blocks the external air outlet 5, and the other arm is away from the external air intake 4. The non-protruding part of the switching plate 6 on the side closer to the external air intake 4 blocks the internal air intake 2. In the second position, the third through hole 7 is located in the suction channel 16. One of the U-shaped protrusions blocks the external air intake 4, and the other arm is away from the external air outlet 5. The non-protruding part of the switching plate 6 on the side closer to the external air outlet 5 blocks the internal air outlet 3.

[0038] A groove 8 can be provided on the inner wall of the U-shaped protrusion of the bottom arm of the fan 1. The bottom arm of the U-shaped protrusion of the switching plate 6 is provided with a slide rail 9 that matches the groove 8, which is used to guide the translation of the switching plate 6.

[0039] In this embodiment, the fan 1 includes a fan blade 10, a housing 11, and a partition 12. The fan blade 10 is disposed inside the housing 11 and is connected to the first driver. The partition 12 is located inside the housing 11 and divides the inner cavity of the housing 11 into a blowing channel 17 and a suction channel 16. In another embodiment, the blowing channel 17 and the suction channel 16 are set independently without the need for the partition 12 to separate them. However, in order to reduce the volume, the two channels are set adjacent to each other.

[0040] In this embodiment, the movement of the switching plate 6 can be achieved by manually stretching or by a control device capable of generating translational movement.

[0041] A sealing strip is added to the sliding gap of the switching plate 6 to improve the sealing effect.

[0042] The housing 11 can be divided into an upper housing and a lower housing, which are connected by snaps or bolts.

The inner blowing port 3, the outer blowing port 5, the inner suction port 2, and the outer suction port 4 are located on the same straight line. The switching plate 6 has a straight plate structure, and a first through hole 13 and a second through hole 14 are opened on the switching plate 6. The interval between the first through hole 13 and the second through hole 14 matches the interval between the inner blowing port 3 and the outer suction port 4, and the interval between the inner suction port 2 and the outer blowing port 5. The flatness of the switching plate 6... The switching plate 6 moves parallel to the four air vents. It can block the inner air intake vent 2 and the outer air blowing vent 5, or block the inner air blowing vent 3 and the outer air intake vent 4.
