Technical Field

[0001] The present invention relates to the technical field of building ventilation structures, and in particular to an energy-saving ventilation structure for green building design. Background Art

[0002] Ventilation is a building environment control technology that controls the spread and harm of air pollutants by means of dilution through ventilation or ventilation removal, etc., to ensure the quality of the indoor and outdoor air environment. Therefore, in building design, corresponding ventilation structures need to be designed for indoor and outdoor air exchange.

[0003] Most of the building ventilation structures in the prior art are to set ventilation openings in the wall and install fans in the ventilation openings, and the air flow in the ventilation openings is driven by starting the fan to achieve ventilation and air change. However, when the common ventilation structure is in use, when the fan inhales the external air flow, foreign objects are easily inhaled, and the foreign objects may collide with the fan and cause damage, resulting in poor durability. Summary of the Invention

[0004] In order to improve durability, the present application provides an energy-saving ventilation structure for green building design.

[0005] The energy-saving ventilation structure for green building design provided by the present application adopts the following technical solutions: An energy-saving ventilation structure for green building design includes a wall, a ventilation block and a fan. The wall is provided with a ventilation opening, the fan is also arranged in the ventilation opening, the ventilation block is provided with an assembly component for installing the ventilation block on the wall, the ventilation block is provided with a ventilation groove communicated with the ventilation opening, and a filter frame is arranged in the ventilation groove, and the filter frame is provided with a plurality of filter nets covering the ventilation groove.

[0006] By adopting the above technical solutions, larger external sundries are blocked by the filter nets covering the ventilation groove. During ventilation, the fan is started to drive the air flow to flow through the ventilation groove and the ventilation opening for air circulation. At the same time, the filter nets block larger sundries, thereby reducing the possibility of sundries entering the ventilation opening and colliding with and damaging the fan, and thus improving durability.

[0007] Preferably, the wall is provided with a solar panel, and the fan is provided with a storage battery signal-connected to the solar panel. The storage battery is used to store the electric energy converted by the solar panel and supply it to the fan.

[0008] By adopting the above technical solutions, the solar panel is connected to the fan storage battery through wires or other means through the reserved line slot holes in the wall. The solar panel converts solar energy and stores it in the storage battery for the fan to use, thereby saving energy and achieving green environmental protection.

[0009] Preferably, the assembly component includes an assembly block and an assembly bolt. The assembly block is arranged on the ventilation block and abuts against the wall body, and the assembly bolt is used to mount the assembly block on the wall body.

[0010] By adopting the above technical solution, during assembly, the ventilation block is attached to the wall body so that the ventilation slots are aligned with the ventilation openings, and at the same time, the assembly block is tightly pressed against the wall body. At this time, the assembly bolt is screwed on to mount the assembly block on the wall body to complete the assembly. The assembly and disassembly are convenient, facilitating the disassembly of the ventilation block for cleaning or maintenance, and timely maintenance and cleaning can reduce the possibility of damage to the ventilation block after long-term exposure during use, improving durability.

[0011] Preferably, the ventilation block is provided with a positioning rod, the wall body is provided with an installation groove communicating with the ventilation opening, the fan is provided with an installation block, the installation block is inserted into the installation groove and can slide in the installation groove, the fan can slide in the ventilation opening, the installation groove is provided with a positioning hole, the positioning rod is inserted into the installation groove and passes through the positioning hole, and the wall body is provided with a fixing component for fixing the installation block.

[0012] By adopting the above technical solution, after releasing the fixation of the fixing component, the ventilation block is disassembled and the positioning rod passes through the positioning hole, and the installation block passes through the installation groove, thereby driving the fan out of the ventilation opening. The disassembly of the fan is convenient for repair and maintenance. At the same time, after installing and fixing the fan, the fan is limited by the positioning rod, reducing the possibility of damage caused by the fan shaking and colliding with the inner wall of the ventilation opening, and improving durability.

[0013] Preferably, the fixing component includes a fixing gear, a first fixing rack, a second fixing rack, a fixing plate and a fixing spring. The inner wall of the installation groove is provided with a fixing groove, the fixing plate is slidably arranged in the fixing groove, the fixing spring is arranged in the fixing groove and connected to the fixing plate, the positioning rod can be inserted into the fixing groove to abut against and push the fixing plate to move, the fixing gear is slidably arranged in the fixing groove and connected to the fixing plate, the inner wall of the fixing groove is provided with a gear groove communicating with the installation groove, the fixing gear is rotatably arranged in the gear groove, the first fixing rack is inserted into the gear groove and meshes with the fixing gear, the second fixing rack is slidably arranged in the gear groove and meshes with the fixing gear, and the installation block is provided with a fixing hole, and the second fixing rack slides and is inserted into the fixing hole.

[0014] By adopting the above technical solution, when installing the fan, the installation block is inserted into the installation groove and abuts against the inner wall of the installation groove. After that, when installing the ventilation block, the positioning rod passes through the positioning groove and the positioning hole, then is inserted into the fixing groove and pushes the fixing plate to move. The movement of the fixing plate compresses the fixing spring. At the same time, when the fixing plate moves, it drives the first fixed rack to move, so as to drive the fixed gear to rotate, and then drives the second fixed rack to slide and insert into the fixing hole of the installation block, realizing the limitation of the installation block. The operation is simple and convenient. At the same time, when disassembling the fan, it is necessary to release the fixation of the fixing component. After disassembling the ventilation block, the positioning rod is driven to disengage from the fixing groove. At this time, the fixing spring pushes the fixing plate to move, drives the first fixed rack to move, and then drives the second fixed rack to disengage from the fixing hole through the fixed gear, thereby releasing the fixation of the installation block. The operation is simple and convenient, facilitating the disassembly and installation of the fan.

[0015] Preferably, the positioning rod is provided with a positioning block, and the positioning block is inserted into the installation groove and abuts against the installation block.

[0016] By adopting the above technical solution, when installing the assembly block, the positioning rod is inserted into the fixing hole while the electric positioning block moves until it abuts against the installation block. After the installation is completed, the positioning block abuts against the installation block, thereby limiting the installation block, reducing the possibility of accidental movement of the installation block, and thus reducing the possibility of damage caused by the collision after the fan moves, improving durability.

[0017] Preferably, the ventilation block is provided with an assembly groove communicating with the ventilation groove. The filter frame is inserted into the assembly groove. The inner wall of the assembly groove is provided with a locking groove. A locking rod is slidably arranged in the locking groove. A locking spring is arranged in the locking groove.

The connecting rod is inserted into the locking groove and connected to the locking rod.

[0018] By adopting the above technical solution, pulling the connecting rod drives the locking rod to slide and compresses the locking spring. Insert the filter frame into the assembly groove, release the connecting rod, and the locking spring restores to push the locking rod into the locking hole of the filter frame, thereby locking the filter frame. At the same time, when it is necessary to disassemble the filter frame, pull the connecting rod to drive the locking rod to withdraw from the locking hole and compress the locking spring during this process. At this time, the filter frame can be disassembled and taken out from the assembly groove. The operation is simple and convenient, improving the convenience of disassembling the filter frame and facilitating the timely replacement or cleaning of the filter frame and the filter mesh.

[0019] Preferably, the ventilation block is provided with an auxiliary groove communicating with the connection hole. The connecting rod is rotatably provided with an auxiliary rod, and the auxiliary rod rotates and is inserted into the auxiliary groove.

[0020] By adopting the above technical solution, after the connecting rod rotates and is inserted into the auxiliary groove, the connecting rod inserted into the auxiliary groove does not protrude from the side wall of the ventilation block, reducing the possibility of the connecting rod being accidentally collided, thereby reducing the possibility of damage and improving durability.

[0021] Preferably, the locking groove and the locking rod are arranged on both sides of the filter box. The connecting rod is connected to the locking rod on one side of the filter box. A transmission cavity is arranged inside the ventilation block. A transmission gear is rotatably arranged in the transmission cavity. A first transmission rack and a second transmission rack are slidably arranged inside the transmission gear. The first transmission rack and the second transmission rack are arranged on both sides of the transmission gear and are both engaged with the transmission gear. The first transmission rack is connected to the connecting rod, and the second transmission rack is connected to the locking rod on the side away from the connecting rod.

[0022] By adopting the above technical solution, when pulling the connecting rod, it drives the locking rod on one side to move and compress the locking spring, and at the same time drives the first transmission rack to move. The rotation of the transmission gear drives the second transmission rack to move, thereby driving the locking rod on the other side to move and compress the locking spring, so as to simultaneously lock or unlock the locking rods on both sides. The operation is simple and convenient, improving the convenience of use.

[0023] Preferably, a filter groove is arranged at the top of the ventilation block. A filter plate for filtering rainwater is arranged inside the filter box. An activated carbon layer is arranged in the filter groove. The ventilation block is provided with a first rainwater groove. The first rainwater groove communicates with the filter groove and the ventilation groove. The filter box is provided with a second rainwater groove communicating with the first rainwater groove.

[0024] By adopting the above technical solution, the filter groove filters rainwater through the filter plate. After the rainwater is preliminarily filtered, it passes through the activated carbon layer, further removing impurities and disinfecting. Finally, it flows through the filter screen from top to bottom after passing through the first rainwater groove and the second rainwater groove, cleaning the filter screen, improving the cleanliness of the filter screen, and at the same time being green, energy-saving and environmentally friendly.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By arranging a wall body, a ventilation block, a fan, a ventilation opening, a ventilation groove, an assembly component, a filter box and a filter screen, the ventilation block is installed on the wall body through the assembly component and the ventilation groove faces the ventilation opening.
