Description

Technical Field

[0001] The invention relates to an auxiliary device for a passive building, in particular to an automatic ventilation device for indoor set doors of a passive building. Background Art

[0002] For passive buildings, the air tightness requirements of their external envelope structures are very strict. The overall ventilation frequency of the building is no more than 0.6 times per hour. The indoor air is provided by a fresh air system. The start and stop of the indoor fresh air system are based on the indoor CO2 and PM2.5 concentration detectors. Since the living room and dining room are areas where people gather densely, the detectors of passive buildings are mostly installed in the living room or dining room, which can detect the indoor CO2 and PM2.5 concentrations at any time.

[0003] During rest at night, in order to ensure privacy, the doors of each independent room are closed. Due to the long rest time at night, the CO2 exhaled by the people resting in the room continues to increase. The CO2 and PM2.5 concentration detectors in the restaurant or living room cannot detect the CO2 concentration in each room. Therefore, the fresh air system cannot be turned on in time, resulting in polluted air in the room. In severe cases, it causes hypoxia, making the people resting in the room feel dizzy and uncomfortable. Summary of the invention

[0004] In order to solve the problem that the existing passive buildings cannot timely detect the indoor CO2 and PM2.5 concentrations during night rest, resulting in hypoxia or dizziness and fatigue for the resting personnel, the present invention provides an automatic ventilation device for indoor door sets of passive buildings.

[0005] The present invention is implemented by adopting the following technical scheme: an automatic ventilation device for indoor set doors of passive buildings, comprising a set door and a door casing, a lock is arranged on the set door, an outer plate at the top of the door casing is provided with an outer vent, an inner vent located at the inner side of the set door is arranged on the top plate of the door casing, an air duct connected with the outer vent and the inner vent is arranged between the outer vent and the inner vent, and a power transmission mechanism and a rotary ventilation mechanism are arranged in the door casing; The power transmission mechanism includes a fixed frame and a transmission shaft located above the fixed frame and arranged vertically, a transmission rod horizontally arranged on the fixed frame and passing through both ends of the fixed frame, a trigger pressure plate in contact with the lock tongue of the lock is fixed at one end of the transmission rod, a rack located above the fixed frame is fixed on the side wall of the trigger pressure plate, a baffle located in the fixed frame is fixed on the transmission rod, and a spring sleeved on the transmission rod is arranged between the baffle and the inner wall of the fixed frame; The transmission shaft is provided with two positioning ear plates I fixed to the inner wall of the door casing and distributed up and down, the lower end of the transmission shaft is provided with a face gear I, the upper end of the transmission shaft is provided with a face gear II, a transmission gear I meshing with the face gear I and the rack is provided between the face gear I and the rack, a rotating shaft I is fixed at the center of the transmission gear I, and two positioning ear plates II fixed to the inner wall of the door casing are provided on the rotating shaft I; The rotary ventilation mechanism includes a movable swing rod and two positioning plates fixed to the door frame, an upper strip hole and a lower strip hole are opened at the upper and lower ends of the movable swing rod, a short shaft fixed to the inner wall of the door frame is passed through the center of the movable swing rod, a positioning rod and a screw rod parallel to each other are arranged between the two positioning plates, a moving block passing through the screw rod and threadedly connected to the screw rod is sleeved on the positioning rod, a lower clamping rod passing through the lower strip hole is fixed on the moving block, and a transmission gear II meshing with the face gear II is arranged at one end of the screw rod; A movable connecting rod is provided at the upper end of the movable rocker arm, an upper clamping rod passing through the upper strip hole is fixed at the middle of the movable connecting rod, and a rotating rocker arm I and a rotating rocker arm II with one end hinged thereto are provided at both ends of the movable connecting rod, a rotating shaft II connected to rotation and perpendicular to the rotating rocker arm I is provided at the other end, and a rotating shaft III connected to rotation and perpendicular to the rotating rocker arm II is provided at the other end, a ventilation plate I matched with the external vent is fixed at the end of the rotating shaft II, a ventilation plate II matched with the internal vent is fixed at the end of the rotating shaft III, and two positioning ear plates III fixed to the door frame are provided on the rotating shaft II and the rotating shaft III.

[0006] The present invention utilizes the lock as a trigger to ensure automatic ventilation between the public area and the indoor room when the indoor door is closed. When the concentration of harmful gases in the indoor room exceeds the standard, the detector in the public area drives the fresh air system to start and deliver fresh air to the room, thus overcoming the problem that the existing passive buildings cannot timely detect the indoor CO2 and PM2.5 concentrations during rest at night, causing hypoxia or dizziness and fatigue for the resting personnel.

[0007] There are two transmission rods, which are arranged in parallel.

[0008] The mechanism design further improves the stability of the connection between the transmission rod and the trigger pressure plate and the baffle, while ensuring the stability of the movement of the transmission rod.

[0009] The structural design of the present invention is reasonable and reliable. When the indoor door is closed, automatic ventilation is achieved between the public area and the indoor rooms, so that the CO2 and PM2.5 concentrations in the room are equivalent to those in the public area. The CO2 and PM2.5 concentration detectors installed in the public area can detect the concentration of harmful gases in the closed room in time, and start the fresh air system in time to deliver fresh air to the room, thereby improving the air cleanliness in each independent room and thus improving the comfort of the living environment.
