Description

Technical Field

[0001] This utility model relates to the field of ventilation devices, specifically to an energy-saving ventilation device for building engineering. Background Technology

[0002] In building construction, ventilation refers to the renewal and circulation of indoor air through natural or mechanical means to ensure indoor air quality. The most commonly used ventilation fan is driven by an electric motor to rotate the fan blades and drive airflow, thus exchanging indoor and outdoor air.

[0003] Existing ventilation fans still have some problems in use: when using existing ventilation fans, dust and impurities adhere to the fan blades, which increases the energy consumption of the ventilation fan and reduces the lifespan of the ventilation fan, resulting in increased ventilation costs.

[0004] Therefore, it is necessary to invent an energy-saving ventilation device for building engineering to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an energy-saving ventilation device for building engineering, in order to solve the problem mentioned in the background art that when existing ventilation fans are in use, dust and impurities adhere to the fan blades, which increases the energy consumption of the ventilation fan, reduces the service life of the ventilation fan, and leads to increased ventilation costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving ventilation device for building engineering, comprising an outer frame, two horizontal plates fixedly connected to the inner wall of the inner cavity of the outer frame, a motor fixedly installed on the outer wall of one horizontal plate, and a drive shaft driven by the output shaft of the motor, the drive shaft being rotatably connected to the other horizontal plate, a fan blade fixedly installed on the outer wall of the drive shaft, a window frame installed on the outside of the outer frame by screws, a dustproof net fixedly installed on the inner wall of the window frame, a cleaning brush movably installed inside the window frame by a sliding cleaning assembly, the sliding cleaning assembly being positioned by a limiting assembly, and the limiting assembly being connected to the window frame without detachment by an anti-detachment assembly.

[0007] Preferably, the two cleaning brushes are arranged in a group and contact both sides of a dustproof net, and the group of cleaning brushes is slidably connected to the window frame through a sliding cleaning component, which makes it convenient to move the cleaning brushes to clean the dustproof net.

[0008] Preferably, the sliding cleaning assembly includes two C-shaped frames fixedly connected to the side walls of a set of two cleaning brushes, and the C-shaped frames are slidably connected to the sliding groove reserved inside the window frame. Furthermore, a lever is fixedly connected to the side wall of one of the C-shaped frames, and the side of the sliding groove where the C-shaped frame is located is open, which facilitates the movement of the cleaning brushes to clean the dust screen.

[0009] Preferably, the limiting component includes a threaded rod that is threadedly connected to the window frame, and the threaded rod is threadedly connected to a threaded groove 1 reserved inside the window frame and a threaded groove 2 reserved inside the C-frame, and a circular plate is fixedly installed on the top of the threaded rod to facilitate twisting of the threaded rod.

[0010] Preferably, there are two threaded grooves, and the two threaded grooves arranged vertically opposite each other are connected to the sliding groove. The upper threaded groove is provided with an anti-disengagement component to ensure that the threaded rod does not detach from the upper threaded groove.

[0011] Preferably, the anti-detachment component includes an annular groove pre-set inside the threaded groove, and a connecting rod is fixedly connected to the inner wall of the annular block rotatably connected inside the annular groove, and the connecting rod is movably matched with the vertical groove reserved inside the threaded rod.

[0012] Preferably, the bottom of the vertical groove is closed, and the inner wall of the vertical groove is attached to the outer wall of the connecting rod to achieve a sliding connection between the upper and lower parts, so that the threaded rod does not fall off the threaded groove at the upper position.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. The present invention uses a circular plate to drive the threaded rod to rotate synchronously, causing the threaded rod to disengage from the lower threaded groove one and threaded groove two in sequence. At this time, it is convenient to move the C-shaped frame to adjust the cleaning brush to clean the dust screen. This eliminates the need for external tools to clean the dust screen, and the cleaning force is controllable, ensuring a longer service life for the dust screen. A clean dust screen prevents debris from entering the ventilation fan while ensuring better ventilation. A clean ventilation fan is more energy-efficient in use.

[0015] 2. When the threaded rod rotates and its position changes, when the vertical groove moves until the end of the vertical groove abuts against the connecting rod, the threaded rod has no room to move, so the threaded rod stops moving. At this time, the threaded rod is always located inside the upper part of the thread groove, thus avoiding the loss of the threaded rod. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-4 The energy-saving ventilation device for building engineering shown includes an outer frame 1. Two horizontal plates 5 are fixedly connected to the inner wall of the inner cavity of the outer frame 1. A motor 6 is fixedly installed on the outer wall of one horizontal plate 5, and the output shaft of the motor 6 is driven by a drive shaft 7. The drive shaft 7 is rotatably connected to the other horizontal plate 5. A fan blade 8 is fixedly installed on the outer wall of the drive shaft 7. A window frame 2 is installed on the outside of the outer frame 1 by screws 4, and a dustproof net 3 is fixedly installed on the inner wall of the window frame 2. A cleaning brush 9 is movably installed inside the window frame 2 by a sliding cleaning assembly 10. The sliding cleaning assembly 10 is positioned by a limiting assembly 11, and the limiting assembly 11 is connected to the window frame 2 without falling off by an anti-detachment assembly 12.

[0025] In use, rotating the circular plate 112 causes the threaded rod 111 to rotate synchronously, causing the threaded rod 111 to disengage from the lower threaded groove 113 and threaded groove 114 in sequence. This facilitates the movement of the C-shaped frame 101 to move the cleaning brush 9 to clean the dust screen 3. This eliminates the need for external tools to clean the dust screen 3, and the cleaning force is controllable, ensuring a longer service life for the dust screen 3. At the same time, the subsequent rotation of the threaded rod 111 causes the threaded rod 111 to match the threaded groove 113 and threaded groove 114, thus limiting the position of the C-shaped frame 101 and ensuring that the cleaning brush 9 does not affect the air intake of the device.

[0026] Two cleaning brushes 9 are arranged in a group and are in contact with both sides of a dustproof net 3. The group of cleaning brushes 9 is slidably connected to the window frame 2 through a sliding cleaning assembly 10. The sliding cleaning assembly 10 includes two C-shaped frames 101 that are fixedly connected to the side walls of the two cleaning brushes 9. The C-shaped frames 101 are slidably connected to the sliding grooves 102 reserved inside the window frame 2. A lever 103 is fixedly connected to the side wall of one of the C-shaped frames 101. The side of the sliding groove 102 where the C-shaped frame 101 is located is open, which makes it easy to move the cleaning brushes 9 to clean the dustproof net 3.

[0027] The C-frame 101 can be moved to adjust the cleaning brush 9 to clean the dustproof net 3. This eliminates the need for external tools to clean the dustproof net 3, and the cleaning force is controllable, ensuring a longer service life for the dustproof net 3.

[0028] The limiting component 11 includes a threaded rod 111 that is threadedly connected to the window frame 2. The threaded rod 111 is threadedly connected to the first threaded groove 113 reserved inside the window frame 2 and the second threaded groove 114 reserved inside the C-shaped frame 101. A circular plate 112 is fixedly installed on the top of the threaded rod 111 to facilitate the twisting of the threaded rod 111. There are two first threaded grooves 113, and the two first threaded grooves 113 arranged vertically opposite each other are connected to the sliding groove 102. An anti-detachment component 12 is provided inside the first threaded groove 113 located at the upper position to ensure that the threaded rod 111 does not detach from the first threaded groove 113 located at the upper position.

[0029] The circular plate 112 can be rotated to cause the threaded rod 111 to rotate and move synchronously, so that the threaded rod 111 disengages from the lower threaded groove 113 and threaded groove 114 in sequence, which makes it convenient to move the C-shaped frame 101 to adjust the movement of the cleaning brush 9.

[0030] The anti-detachment component 12 includes an annular groove 121 pre-set inside the threaded groove 113, and a connecting rod 123 is fixedly connected to the inner wall of the annular block 122 rotatably connected inside the annular groove 121. The connecting rod 123 is movably matched with the vertical groove 124 reserved inside the threaded rod 111. In this way, when the threaded rod 111 rotates, the connecting rod 123 and the annular block 122 rotate synchronously without affecting the rotation of the threaded rod 111. The bottom of the vertical groove 124 is closed, and the inner wall of the vertical groove 124 is attached to the outer wall of the connecting rod 123 to achieve a sliding connection between the upper and lower parts. This prevents the threaded rod 111 from detaching from the threaded groove 113 at the upper position.

[0031] When the threaded rod 111 rotates and moves in position, the vertical groove 124 moves synchronously outside the connecting rod 123. When the vertical groove 124 moves until its end abuts against the connecting rod 123, the threaded rod 111 has no room to move, so the threaded rod 111 stops moving. At this time, the threaded rod 111 is always located inside the upper threaded groove 113, thus preventing the threaded rod 111 from being lost.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
