DETAILED DESCRIPTION

[0025] The present invention is further explained with reference to the accompanying drawings.

[0026] See also Figures 1 to 7 The air outlet system of a car air conditioner shown in the figure includes a power element and a plurality of air outlets 3, wherein the plurality of air outlets 3 are respectively arranged at different positions in the car, wherein the air outlets 3 include a shell and air guide blades arranged in the shell for adjusting the wind direction, wherein the air guide blades include a main blade 3.1 for guiding the air up and down and a secondary blade 3.2 for guiding the air left and right; the main blade 3.1 and the secondary blade 3.2 respectively have a transmission shaft 3.4.

[0027] The power element includes an air pump 1 for providing air pressure and a main distribution component 2 matched with the air pump 1, wherein the main distribution component 2 includes an inlet and a plurality of outlets, and the number of outlets of the main distribution component 2 corresponds to the number of air outlets 3. The inlet of the main distribution component 2 is connected to the air pump 1, and the outlet of the main distribution component 2 is matched with each air outlet 3 respectively.

[0028] Specifically, each of the air outlets 3 includes a distributor 3.3 and two sets of control mechanisms, the distributor 3.3 has an inlet and multiple outlets, one of the control mechanisms cooperates with the main blade 3.1, and the other control mechanism cooperates with the secondary blade 3.2, each control mechanism includes a piston 3.5 and an airtight base 3.6, the airtight base 3.6 has a mounting cavity 3.61 with two ends through, wherein the piston 3.5 is slidably arranged in the mounting cavity 3.61 of the airtight base 3.6, and the piston 3.5 has a first action end 3.5 arranged oppositely. 1 and a second action end 3.52 and a connecting portion 3.53 extending out of the mounting cavity 3.61, that is, the first action end 3.51 is arranged at one end of the piston member 3.5, the second action end 3.52 is arranged at the other end of the piston member 3.5, and the connecting portion 3.53 is arranged in the middle of the piston member 3.5, the piston member 3.5 in one control mechanism is connected to the transmission shaft 3.4 of the main blade 3.1 through the connecting portion 3.53, and the piston member 3.5 in the other control mechanism is connected to the transmission shaft 3.4 of the secondary blade 3.2 through the connecting portion 3.53.

[0029] The distributor 3.3 has four outlets, two of which are connected to the two ends of the installation cavity 3.61 in one of the control mechanisms through two output pipelines, and the other two outlets of the distributor 3.3 are connected to the two ends of the installation cavity 3.61 in another control mechanism through two output pipelines.

[0030] When it is necessary to control an air outlet 3 for air guiding, the air pressure output by the air pump 1 is transmitted to the distributor 3.3 of the air outlet 3 through the main distribution component 2, and then the air pressure is distributed to the main blade 3.1 and the secondary blade 3.2 of the air outlet 3 through the distributor 3.3. If it is necessary to guide the air up and down, the air pressure is applied to the control mechanism matched with the main blade 3.1 through the distributor 3.3, and the two outlets act on the mounting cavity 3.61 of the airtight base 3.6 of the control mechanism through two output pipelines respectively. Due to the difference in air pressure at both ends of the mounting cavity 3.61, the air pressure acting on the first acting end 3.51 and the second acting end 3.52 of the piston component 3.5 is different, so as to push the piston component 3.5 to move. When the piston component 3.5 moves, it can drive the rotating shaft of the main blade 3.1 to rotate through the connecting part 3.53, thereby adjusting the angle of the main blade 3.1 and realizing the final adjustment of the up and down air outlet angles.

[0031] If it is necessary to guide the air to the left and right, the air pressure is applied to the control mechanism matched with the secondary blade 3.2 through the distributor 3.3, and the two outlets act on the installation cavity 3.61 of the airtight base 3.6 of the control mechanism through two output pipelines. Due to the difference in air pressure at both ends of the installation cavity 3.61, the air pressure acting on the first action end 3.51 and the second action end 3.52 of the piston member 3.5 is different, which pushes the piston member 3.5 to move. When the piston member 3.5 moves, it can drive the rotating shaft of the secondary blade 3.2 to rotate through the connecting part 3.53, thereby adjusting the angle of the secondary blade 3.2 and realizing the final adjustment of the left and right air outlet angles.

[0032] Moreover, by setting the installation cavity 3.61 to cooperate with the piston member 3.5, the movement of the piston member 3.5 can be guided to ensure that the piston member 3.5 can move stably. In addition, the setting of the installation cavity 3.61 can seal the gas output from the output pipeline to ensure that the air pressure can act on the first action end 3.51 and the second action end 3.52 of the piston member 3.5. In addition, the first action end 3.51 and the second action end 3.52 are respectively sleeved with a sealing ring 3.54, and the first action end 3.51 and the second action end 3.52 are fitted with the inner wall of the installation cavity 3.61 through the sealing ring 3.54, which can further ensure that the air pressure can act on the first action end 3.51 and the second action end 3.52, reducing the leakage of the air pressure.

[0033] In addition, the distributor 3.3 is provided with a secondary control valve for controlling the size of the air pressure outputted from each outlet thereof. By providing the secondary control valve, the size of the air pressure outputted from each outlet can be controlled, thereby controlling the difference in air pressure acting on the first acting end 3.51 and the second acting end 3.52 on the piston member 3.5, and ultimately controlling the rotation of the main blade 3.1 and the secondary blade 3.2.

[0034] The main distribution component 2 is provided with a main control valve for controlling the air pressure outputted from each outlet. By setting a secondary control valve, the air pressure outputted from each outlet can be controlled, thereby enabling the air pressure to be reasonably distributed to the air outlets 3 that need to be adjusted according to user needs, and the design is more reasonable.

[0035] The air outlet system of the present invention sets the power element as an air pump 1, and applies the air pressure output by the air pump 1 to multiple air outlets 3 through the main distribution component 2, thereby driving the air guide blades on different air outlets 3 to rotate to guide the air. Only one air pump 1 is needed to control multiple air outlets 3, which reduces costs, has a simple structure, saves space, and reduces the weight of the vehicle body.

[0036] As an improvement of the present invention, the airtight base 3.6 is further provided with a pressure relief hole 3.62 connected to the mounting chamber 3.61. By providing the pressure relief hole 3.62, when gas enters the two ends of the mounting chamber 3.61, the gas will be compressed when the piston member 3.5 moves, thereby discharging the gas through the pressure relief hole 3.62, thereby facilitating the movement of the piston member 3.5. In addition, there are a plurality of pressure relief holes 3.62, and the plurality of pressure relief holes 3.62 are arranged at non-uniform intervals, that is, among the plurality of pressure relief holes 3.62, the spacing between two adjacent pressure relief holes 3.62 is different. Since the air intake pressure at the two ends of the mounting chamber 3.61 corresponds to the rotation angle of the piston member 3.5 one by one, increasing the rotation angle requires increasing the number of openings, but increasing the number of openings will affect the precise movement of the mechanism. Therefore, in the present scheme, a plurality of pressure relief holes 3.62 are arranged at non-uniform intervals, leaving a control margin, increasing the adjustable rotation angle of the piston member 3.5, thereby controlling the change angle of the air guide blade as much as possible.

[0037] The above are only preferred embodiments of the present invention, so all equivalent changes or modifications made according to the structure, features and principles of the patent application scope of the present invention are included in the scope of the patent application of the present invention.
