[0003] Ventilation equipment is also an important part of architectural design. During the building construction process, a large amount of harmful gases may exist inside the construction site and it is difficult to quickly discharge them without wind, which will affect the physical health of the staff. Therefore, a ventilation device needs to be set up to provide guidance for the discharge of others inside before the building is completed.

When the utility model is not in use, the air inlet can be closed. When in use, it can be opened, and the opening is convenient. It can be achieved by pulling and rotating the sealing plate, so that the first insert is inserted into the short slot to provide blocking and limiting. The sealing plate does not cover or block the bottom end of the tee pipe to achieve opening. When exhausting, it can be filtered through a high-efficiency filter to avoid the discharge of harmful gases and avoid environmental pollution. Further, the top end of the tee pipe is closed by a sealing cover, and the threaded connection is adopted, which is convenient for opening and closing, so as to facilitate the maintenance of the fan blade and is easy to use.

[0032] Please refer to Figures 1-9, an embodiment provided by the present utility model: a ventilation device for architectural design, comprising a pipe body 3, a limiting mechanism 8 and a mounting mechanism 9. A protective grille 2 is movably arranged at the right port of the pipe body 3 through fixing bolts. A positioning groove 6 is opened at the bottom end of the inner wall of the pipe body 3. A positioning block 7 is movably arranged inside the positioning groove 6. A filter 1 is fixedly connected to the top of the positioning block 7. A mounting block 10 is fixedly connected to the top of the filter 1. Mounting mechanisms 9 are arranged at both ends of the mounting block 10. The mounting mechanism 9 includes a mounting cavity 902 which is opened on the outer walls at both ends of the mounting block 10. Limiting holes 901 are opened at one ends of the two mounting cavities 902 away from each other. A second spring 903 is arranged inside the mounting cavity 902. Moving plates 905 are fixedly connected to one ends of the two second springs 903 away from each other. Limiting blocks 904 are fixedly connected to one ends of the two moving plates 905 away from each other. And the limiting blocks 904 are movably arranged inside the limiting holes 901. A pulling block 12 is fixedly connected to the top of the mounting block 10. A limiting abutting frame 11 is arranged on the right side of the filter 1;

[0033] Specifically, as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 shown, when in use, when it is necessary to disassemble the filter 1, the two limiting blocks 904 can be pressed to make the limiting blocks 904 move along the direction away from the limiting holes 901 and close to the mounting cavity 902. When the limiting blocks 904 move to a suitable position, the pulling block 12 is pulled upward until the filter 1 is separated from the pipe body 3, thus completing the disassembly of the filter 1. When it is necessary to install the filter 1, the limiting blocks 904 are pressed again, and then the filter 1 is placed above the pipe body 3 and the filter 1 is moved into the pipe body 3. When the limiting blocks 904 move to the opposite side of the limiting holes 901, at this time, the second spring 903 is no longer under external force and will drive the limiting blocks 904 to insert into the limiting holes 901, thus completing the fixation of the mounting block 10 and further completing the installation of the filter 1. By facilitating the disassembly, cleaning or replacement and installation of the filter 1, the convenience is improved, and further the ventilation effect of the ventilation device is improved, solving the problem that the air is filtered by the filter 1, but the filter 1 is fixedly installed, it is not convenient to disassemble, clean or replace and install the filter 1, the convenience is poor, and the ventilation effect of the ventilation device will be reduced.

[0034] On the right side of the limit abutting frame 11, an installation frame 5 is movably arranged. A blower 4 is installed inside the installation frame 5. Limit mechanisms 8 are arranged at both ends of the installation frame 5. The limit mechanism 8 includes a limit sleeve 801. An activity plate 806 is movably arranged inside the limit sleeve 801. Fixing holes 803 are formed on one side of the two activity plates 806 close to each other. A fixing rod 807 is movably arranged inside the fixing hole 803, and the fixing rod 807 is fixedly connected to the activity plate 806. Pulling rods 805 are fixedly connected to one side of the two activity plates 806 away from each other. A first spring 802 is sleeved on the outer wall of the pulling rod 805. Pulling plates 804 are fixedly connected to one side of the two pulling rods 805 away from each other.

[0035] Specifically, as Figure 3 , Figure 5 , Figure 6 and Figure 9 shown, during use, when the blower 4 has abnormal operation and needs to be disassembled and repaired, the pulling plates 804 can be pulled in the direction away from each other until the fixing rod 807 disengages from the fixing hole 803. Then, the installation frame 5 is pulled outward until the installation frame 5 disengages from the pipeline body 3, thus completing the disassembly of the blower 4. When the blower 4 after repair needs to be installed, the pulling plates 804 are pulled in the direction away from each other again. When the pulling plates 804 move to a suitable position, the installation frame 5 is pushed into the pipeline body 3 until the installation frame 5 abuts against the limit abutting frame 11. Then, the pulling plates 804 are released. At this time, the elasticity of the first spring 802 can be utilized to drive the fixing rod 807 to insert into the fixing hole 803, thus completing the fixation of the installation frame 5 and further completing the installation of the blower 4. By facilitating the disassembly, repair and installation of the blower 4, the ventilation efficiency can be effectively guaranteed, thereby improving the practicability of the device. It should be noted that during the disassembly and assembly process of the blower 4, the fixing bolts need to be rotated to complete the disassembly of the protective grille plate 2, and after the blower 4 is installed, the protective grille plate 2 needs to be installed through the fixing bolts.

[0036] Working principle: In this application, when the filter 1 needs to be disassembled, the two limit blocks 904 can be pressed to make the limit blocks 904 move in the direction away from the limit holes 901 and close to the installation cavity 902. When the limit blocks 904 move to a suitable position, the pull block 12 is pulled upward until the filter 1 is detached from the pipe body 3, thus completing the disassembly of the filter 1. When the filter 1 needs to be installed, the limit blocks 904 are pressed again, and then the filter 1 is placed above the pipe body 3 and moved inward into the pipe body 3. When the limit blocks 904 move to the opposite side of the limit holes 901, at this time, the second spring 903 is no longer under external force and will drive the limit blocks 904 to insert into the limit holes 901, thus completing the fixation of the installation block 10 and further completing the installation of the filter 1. By facilitating the disassembly, cleaning or replacement and installation of the filter 1, the convenience is improved, and further the ventilation effect of the ventilation device is improved. Secondly, when the fan 4 has abnormal operation and needs to be disassembled and overhauled, the pull plates 804 can be pulled in the direction away from each other until the fixing rods 807 are detached from the fixing holes 803, and then the installation frame 5 is pulled outward until the installation frame 5 is detached from the pipe body 3, thus completing the disassembly of the fan 4. When the overhauled fan 4 needs to be installed, the pull plates 804 are pulled in the direction away from each other again. When the pull plates 804 move to a suitable position, the installation frame 5 is pushed inward into the pipe body 3 until the installation frame 5 abuts against the limit abutting frame 11, and then the pull plates 804 are released. At this time, the elasticity of the first spring 802 can be utilized to drive the fixing rods 807 to insert into the fixing holes 803, thus completing the fixation of the installation frame 5 and further completing the installation of the fan 4. By facilitating the disassembly, overhaul and installation of the fan 4, the ventilation efficiency can be effectively guaranteed, thus improving the practicability of the device.
