The rectangular damper motor 5-2 drives the first bevel gear 5-1-5 to rotate via the second bevel gear 5-2-1. The first bevel gear 5-1-5 drives the lower adjusting blade 5-1-3. The rotating gear 5-1-4 of the -3 rotates, which in turn drives the lower adjusting blade 5-1-3 to deflect at an angle. The rotating gear 5-1-4 of the upper adjusting blade 5-1-2, under the action of the rotating gear 5-1-4 of the lower adjusting blade 5-1-3, drives the upper adjusting blade 5-1-2 to deflect at an angle. The upper adjusting blade 5-1-2 and the lower adjusting blade 5-1-3 rotate in opposite directions at the same time to adjust the opening and closing degree of the rectangular air valve 5-1, change the air supply intensity of each sub-air supply channel 2-3, realize oscillating air supply, and reduce the feeling of blowing air during cooling.

[0047] As a preferred embodiment, the flow equalization component 6 includes a honeycomb plate 6-1 and a screen 6-2 arranged coaxially.

[0048] As a preferred embodiment, the top of the housing 1 is provided with a return air installation port 7, and a return air assembly 8 is installed in the return air installation port 7. When the combined air supply device delivers warm air, the return air assembly 8 controls the precise delivery of warm air. The return air installation port 7 is located between the rectangular air valve 5-1 and the honeycomb panel 6-1. The return air installation port 7 is connected to the uppermost sub-air supply channel 2-3. The return air assembly 8 includes an installation frame 8-1.

[0049] A raised edge 8-5 is integrally formed on one side of the top of the mounting frame 8-1. A first sliding groove 8-6 is formed on the raised edge 8-5. A second sliding groove 8-7 is formed on the side wall of the mounting frame 8-1 corresponding to the raised edge 8-5. The swivel-type air valve 8-2 includes a swivel 8-2-1. A sliding rod 8-2-2 is provided on the side wall of the swivel 8-2-1 facing the second sliding groove 8-7.

When the air conditioning system delivers warm air, the swivel-type air valve 8-2-5 and the return air fan 8-3 are opened, and the rectangular air valve 5-1 in the uppermost sub-supply air channel 2-3 is closed. The return air fan 8-3 circulates the indoor airflow to the uppermost sub-supply air channel 2-3, while the rectangular air valves 5-1 in the other sub-supply air channels 2-3 are opened, delivering warm air that is higher than the indoor temperature. After the warm air is delivered by the air control component 4, the warm airflow will be deflected upwards. The room temperature airflow path delivered by the uppermost sub-supply air channel 2-3 tends to be horizontal, which can effectively suppress the upward deflection of the warm airflow delivered by the other sub-supply air channels 2-3 below, thus achieving precise air delivery.

[0050] As a preferred embodiment, the wind control component 4 in this embodiment includes a louvered outer shell 4-1 fitted onto the outlet end of the housing 1. A louvered motor 4-2 is installed on the side wall of the louvered outer shell 4-1 facing the air supply channel 2. An upper louvered blade group 4-3 and a lower louvered blade group 4-4 arranged in parallel are installed on the inner side of the louvered outer shell 4-1.

[0051] Both the upper 100-blade group 4-3 and the lower 100-blade group 4-4 include multiple parallel blades 4-5. The ends of the multiple blades 4-5 are installed on the inner wall of one side of the louver outer shell 4-1, and the other ends of the multiple blades 4-5 are fixedly connected to an eccentric wheel 4-6.

[0052] The eccentric rotating wheel 4-6 of the 100-blade assembly is mounted on a vertically arranged first traction rod 4-3-1. The bottom end of the first traction rod 4-3-1 is provided with a first drive turntable 4-3-2. The end face of the first drive turntable 4-3-2 facing the louver motor 4-2 is provided with a first drive shaft 4-3-3 and a first eccentric shaft 4-3-4. The first eccentric shaft 4-3-4 is mounted on the first traction rod 4-3-1. The end of the first drive shaft 4-3-3 is provided with a third bevel gear 4-3-5.

[0053] The shafts of the eccentric wheels 4-6 of the lower louver blade assembly 4-4 are all mounted on a vertically arranged second traction rod 4-4-1. The bottom end of the second traction rod 4-4-1 is provided with a second drive turntable 4-4-2. The end face of the second drive turntable 4-4-2 facing the louver motor 4-2 is provided with a second drive shaft 4-4-3 and a second eccentric shaft 4-4-4. The second eccentric shaft 4-4-4 is mounted on the second traction rod 4-4-1. The end of the second drive shaft 4-4-3 is provided with a fourth bevel gear 4-4-5.

[0054] The drive shaft of the louver motor 4-2 is equipped with a fifth bevel gear 4-2-1. The fourth bevel gear 4-4-5 meshes with the third bevel gear 4-3-5 and the fifth bevel gear 4-2-1 respectively. The louver motor 4-2 drives the fifth bevel gear 4-2-1 to rotate the fourth bevel gear 4-4-5. The fourth bevel gear 4-4-5 drives the second pull rod 4-4-1 to move up and down, thereby causing the blades 4-5 of the lower louver blade group 4-4 to swing up and down. At the same time, the fourth bevel gear 4-4-5 drives the third bevel gear 4-3-5 to rotate in the opposite direction. The three bevel gear 4-3-5 drives the first traction rod 4-3-1 to move up and down, guiding the blades 4-5 of the upper 100-blade group 4-3 to swing up and down. The upper 100-blade group 4-3 and the lower 100-blade group 4-4 rotate in different directions at the same time and form a certain angle. When it is necessary to achieve energy dissipation through collision, this angle is determined by the position of the target area to ensure that the airflow delivered by the wind control component 4 collides near the target area, thereby reducing the feeling of blowing air during cooling. When it is not necessary to achieve energy dissipation through collision, the blades 4-5 of the upper 100-blade group 4-3 and the lower 100-blade group 4-4 can be in a horizontal state.

[0055] As a preferred embodiment, the screen 6-2 in this embodiment has at least four layers.

[0056] As a preferred embodiment, the inner wall of the housing 1 is provided with multiple grooves for placing the blower motor 3-2, the return air motor 8-4, the rectangular damper motor 5-2, and the louver motor 4-2, respectively, so as to ensure that each motor remains stable during operation.

[0057] As a preferred embodiment, both the rectangular damper motor 5-2 and the louver motor 4-2 in this embodiment are stepper motors to achieve frequent cyclic rotation.

[0058] As a preferred embodiment, there are at least three sub-air supply channels 2-3 in this embodiment. If the scale of the combined air supply device is expanded, different numbers of sub-air supply channels 2-3, air supply mode adjustment unit 5 and flow equalization component 6 can be adapted.

[0059] As a preferred embodiment, both the blower motor 3-2 and the return air motor 8-4 are connected to an adjustable power supply. By adjusting the voltage, the air volume of the blower 1-1 and the return air motor 1-2 can be controlled to meet the user's needs.

[0060] In actual operation of this embodiment:

[0061] When the combined air supply device is used in summer, it needs to provide cool air to the target indoor area. The air conditioning system provides cooling from the heat source and cold source. The air supply fan 3-1 starts working and delivers the cool air to the air supply channel 2. The air supply speed is adjusted by adjusting the air supply motor 3-2. The return air assembly 8 is in the closed state. The vane damper 8-2 completely covers the return air fan 8-3. The cool air is delivered into each sub-air supply channel 2-3. At this time, each rectangular damper 5-1 is open. The upper adjusting blade 5-1-2 and the lower adjusting blade 5-1-3 are rotated periodically by controlling the rectangular damper motor 5-2. This continuously adjusts the relative opening of the upper adjusting blade 5-1-2 and the lower adjusting blade 5-1-3. The opening of each air supply mode adjustment unit 5 is different, so the intensity of the cool air in each sub-air supply channel 2-3 is different. The cold airflow passes through the honeycomb panel 6-1 and the four-layer screen 6-2 in sequence before being sent to the air control component 4. At this time, the air control component 4 has two working states: when the blades 4-5 are all in a parallel state, after the cold airflow is sent out by the air control component 4, due to the different airflow intensity of each sub-air supply channel 2-3 and the continuous change of the air supply speed front, the airflow "sways", thereby reducing the feeling of blowing; when the blades 4-5 are adjusted by the louver motor 4-2, there is a certain angle between the blades 4-5 of the upper louver group 4-3 and the lower louver group 4-4. Therefore, after the airflow of each sub-air supply channel 2-3 passes through the air control component 4, it collides near the air supply target area, eliminating part of the air supply kinetic energy, thereby reducing the feeling of blowing.

[0062] When the combined air supply unit is used in winter, it needs to provide warm air to the target indoor area. The air conditioning system uses its cold and heat sources for heating, and the supply fan 3-1 starts working, delivering warm air to the supply air duct 2. Adjusting the supply fan motor 3-2 changes the air supply speed. At this time, the rectangular air valve 5-1 in the uppermost sub-supply air duct 2-3 closes, while all other rectangular air valves 5-1 open. Simultaneously, the swivel valve 8-2 opens, and the return air fan 8-3 starts working, delivering indoor return air to the uppermost sub-supply air duct 2-3. The return air volume can be controlled by adjusting the return air fan motor 8-4. The remaining... Warm air is delivered in the sub-air supply duct 2-3. The indoor return air and warm air are delivered to the air control component 4 after passing through the honeycomb panel 6-1 and the four-layer screen 6-2. At this time, the blades 4-5 of the air control component 4 are all in a parallel state. Since the temperature of the warm air delivered by the other sub-air supply ducts 2-3 is higher than the indoor temperature, the warm air will be deflected upward after being delivered by the air control component 4. The room temperature airflow delivered by the uppermost sub-air supply duct 2-3 tends to be horizontal, which can effectively suppress the upward deflection of the warm air delivered by the other sub-air supply ducts 2-3 below, thus achieving precise air delivery.
