Beneficial effect

1. When the device is in use, the opening and closing control mechanism can control the opening and closing device of the energy-saving ventilation mechanism, so that when the energy-saving ventilation mechanism is closed, the frame assembly is in a closed state, and the interaction between indoor and outdoor air will not be realized. When the energy-saving ventilation mechanism is in the open state, it can realize the gas interaction of the indoor unit, and realize the operation of ventilation and ventilation. It is easy to use, and the ventilation and ventilation can be realized without opening doors and windows. The open position can adapt to the needs of indoor and outdoor ventilation in different environments, improving the flexibility, safety, adaptability and practicability of the device.

2. The energy-saving ventilation mechanism has two states of use: open and closed. When the use positions of the opening and closing channels of the outer connecting column and the inner connecting column coincide, the indoor and outdoor air can interact through the connecting channel and the opening and closing channel, thereby Realize the use of indoor and outdoor ventilation. When the use positions of the opening and closing channels of the outer connecting column and the inner connecting column are staggered, the energy-saving ventilation mechanism is in a closed state at this time, and the interactive use of indoor and outdoor air cannot be realized, and it can be adapted to different uses. demand, highly adaptable.

3. The use status of all energy-saving ventilation mechanisms can be controlled by the opening and closing control mechanism. When the operating lever is pulled left and right, the operating lever drives the control lever to move synchronously, so that the drive block inside the control lever can move synchronously with the control lever. When the driving block is moving, the driving block under the action of the driving top spring opens and closes the gear rack and the teeth of the opening and closing gear. The same function of controlling the opening and closing state of the energy-saving ventilation mechanism is provided, which is flexible in use and convenient in adjustment.

4. The use position of the control rod can be positioned by the positioning block. The positioning block makes the operating rod always at the lowest position of the positioning groove under the action of the positioning top spring, so that the control rod will not move accidentally when in use to change the energy-saving ventilation The use status of the mechanism is stable.

5. The indicator block can indicate the use status of the energy-saving ventilation mechanism. When the energy-saving ventilation mechanism is closed, the indicator block retracts into the interior of the installation attachment frame, and the single-control protrusion is located at the innermost end of the single-control slot. When the energy-saving ventilation When the mechanism switches from the closed state to the open state, the inner connecting column will rotate, so that when the inner connecting column rotates, the single control groove can drive the indicator block to move outward through the single control protrusion to protrude from the inside of the attached frame, so as to realize the indication A function of the state of use of the energy-saving ventilation mechanism.

6. The use state of each energy-saving ventilation mechanism can also be switched and controlled separately through the indicator block. When the energy-saving ventilation mechanism is in the open state, when the indicator block is pressed into the inside of the installation attachment frame, the energy-saving ventilation mechanism can be switched To the closed state, when the indicator block moves to the inside of the installation frame, the single control protrusion drives the inner connecting column to rotate through the single control groove, and in this process, because the force of the positioning top spring on the positioning block is greater than that of the driving top spring on the driving The force of the block, so that when the inner connecting column rotates, the beveled sides of the teeth of the opening and closing gear and the opening and closing rack squeeze each other so that the opening and closing rack moves downward to avoid the rotation of the opening and closing gear, so that the rest of the energy-saving ventilation is not changed. When the mechanism is in use, the corresponding energy-saving ventilation mechanism is closed separately. It is easy to use and flexible to adjust. It can adapt to the needs of indoor and outdoor ventilation in different environments, and has strong adaptability.

in the second step, when indoor and outdoor ventilation is carried out, or after the ventilation is finished, the operating rod (3031) is pulled leftwards or rightwards, so that the operating rod (3031) drives the control rod (301) to move synchronously, the driving block (302) in the control rod (301) can move synchronously along with the control rod (301), and when the driving block (302) moves, the driving block (302) opens and closes the gear teeth meshing transmission of the rack (3021) and the opening and closing gear (4022) under the action of the driving top spring (3022) to drive the inner side communication column (402) to rotate, so that the use position of the opening and closing channel (4021) of the inner side communication column (402) is changed, and the opening and closing channels (4021) of the outer side communication column (401) and the inner side communication column (402) are staggered or overlapped;

in the second step, when indoor and outdoor ventilation is performed, the energy-saving ventilation mechanism (4) is switched from a closed state to an open state, and the inner side communication column (402) is rotated, so that the single control groove (4023) drives the indication block (403) to move outwards through the single control protrusion (4031) to protrude out of the installation auxiliary frame (2) so as to indicate that the energy-saving ventilation mechanism (4) is in the open state to perform ventilation;

in the second step, the using position of the control rod (301) can be positioned through the positioning block (304), and the positioning block (304) enables the operating rod (3031) to be always positioned at the lowest position of the positioning groove (3041) under the action of the positioning top spring (3042), so that the control rod (301) cannot move accidentally to change the using state of the energy-saving ventilation mechanism (4) when in use;

in the second step, when the energy-saving ventilation mechanism (4) is in an open state, the indication block (403) is pressed into the auxiliary mounting frame (2), the energy-saving ventilation mechanism (4) can be switched to a closed state, and the indication block (403) moves towards the inside of the auxiliary mounting frame (2), so that the single control protrusion (4031) drives the inner side communication column (402) to rotate through the single control groove (4023), and in the process, because the acting force of the positioning top spring (3042) on the positioning block (304) is greater than the acting force of the driving top spring (3022) on the driving block (302), when the inner side communication column (402) rotates, the inclined sides of the gear teeth of the opening and closing gear (4022) and the opening and closing rack (3021) are pressed against each other, so that the opening and closing rack (3021) moves downwards, and the rotation of the opening and closing gear (4022) is avoided, and the corresponding energy-saving ventilation mechanism (4) is independently closed without changing the use state of the other energy-saving ventilation mechanisms (4).
