Abstract
Description
Technical Field
[0001] This application relates to the field of building decoration technology, and in particular to a ventilation and dust removal device for building decoration. Background Technology
[0002] Currently, during the decoration and renovation of some buildings, a lot of dust is generated inside due to the construction work. This dust mostly floats inside the building and also reduces the air quality inside the building. Therefore, ventilation is required, which requires the use of ventilation and dust removal devices. However, existing ventilation devices simply exhaust the polluted air inside the building directly or after purification to the outside, and then replenish the fresh air to maintain the indoor air environment. But they also exhaust indoor dust into the outside, which reduces the quality of the outside air and does not meet environmental protection requirements. Utility Model Content
[0003] In order to address the problem that existing ventilation devices only discharge polluted indoor air or purify it before exhausting it to the outside and then replenish it with fresh air to maintain the indoor air environment, but also discharge indoor dust into the outside, which reduces the quality of outside air and does not meet environmental protection requirements, this application provides a ventilation and dust removal device for building decoration.
[0004] The ventilation and dust removal device for building decoration provided in this application adopts the following technical solution:
[0005] A ventilation and dust removal device for building decoration includes an externally threaded fixed cylinder and a fan. An installation component 1 is fixedly sleeved on the outer surface of one end of the externally threaded fixed cylinder. The fan is fixedly installed inside the externally threaded fixed cylinder through the installation component 2. An internally threaded collar is threadedly sleeved on the other end of the externally threaded fixed cylinder. A dust collector bag is adhered to the outer surface of the internally threaded collar. An opening is provided at one end of the dust collector bag. A discharge port is fixedly embedded inside the opening. A threaded cap is threadedly sleeved on the outer surface of the discharge port.
[0006] Preferably, the mounting component consists of a mounting ring and expansion bolts. The mounting ring is fixedly sleeved on one end of the external threaded fixing cylinder. Four circular holes are opened on one side of the mounting ring, and the four expansion bolts respectively movably pass through the four circular holes.
[0007] Preferably, the second mounting component consists of a mounting sleeve and screws. The mounting sleeve is movably inserted into the interior of the externally threaded fixing sleeve. Four insertion holes are provided on one side of the mounting sleeve, and four screws are movably inserted through the four insertion holes respectively. All four screws are threadedly connected to the externally threaded fixing sleeve.
[0008] Preferably, the screw has a retaining ring inside, which is fixedly sleeved on the outer surface of the fan. Two retaining rods are welded to the outer surface of the retaining ring, and both retaining rods are welded to the inner wall of the mounting cylinder.
[0009] In summary, this application includes the following beneficial technical effects: by using an internally threaded collar to fit the dust collector bag onto the other end of an externally threaded fixed cylinder, and then using the suction generated by the fan in the externally threaded fixed cylinder when it is working, the air inside the building is sucked away and circulated, thereby achieving the purpose of ventilation inside the building. The air sucked away by the fan is filtered by the dust collector bag and then runs out to the outside of the building. At this time, the dust is filtered by the dust collector bag and remains inside the dust collector bag, thereby achieving the purpose of dust removal. Attached Figure Description

Detailed Implementation
[0015] The following is combined with Figure 1 -Appendix Figure 4 This application is described in further detail.
[0016] Example 1:
[0017] A ventilation and dust removal device for building decoration, referring to Figure 1-4The system includes an externally threaded fixing cylinder 1 and a fan 3. An installation component 2 is fixedly fitted onto the outer surface of one end of the externally threaded fixing cylinder 1. The installation component 2 consists of an installation ring 21 and expansion bolts 22. The installation ring 21 is fixedly fitted onto one end of the externally threaded fixing cylinder 1. Four circular holes are opened on one side of the installation ring 21, and four expansion bolts 22 are movably inserted through the four circular holes. After the externally threaded fixing cylinder 1 is inserted through the building's ventilation opening, four wall holes are opened in the building wall. Then, one end of each of the four expansion bolts 22 is inserted into the four wall holes, and the four expansion bolts 22 are tightened, thus fixing the externally threaded fixing cylinder 1 to the building. In the ventilation opening of the device, the fan 3 is fixedly installed inside the externally threaded fixed cylinder 1 via mounting component 2 4. The fan 3 is electrically connected to an external power supply via an external switch. Mounting component 2 4 consists of a mounting cylinder 41 and screws 42. The mounting cylinder 41 is movably inserted into the internal cavity of the externally threaded fixed cylinder 1. Four insertion holes are provided on one side of the mounting cylinder 41, and four screws 42 are movably inserted through the four insertion holes respectively. All four screws 42 are threadedly connected to the externally threaded fixed cylinder 1, thus fixing the mounting cylinder 41 inside the externally threaded fixed cylinder 1. A retaining ring 43 is provided inside the screw 42, and the retaining ring 43 is fixedly sleeved on the outer surface of the fan 3. Two fixing rods 44 are welded to the outer surface of the fixing ring 43. Both fixing rods 44 are welded to the inner wall of the mounting cylinder 41, which allows the fan 3 to be suspended and supported inside the external threaded fixing cylinder 1, and at the same time fixes the fan 3. The other end of the external threaded fixing cylinder 1 is threaded with an internal threaded collar 51. A dust collector bag 52 is adhered to the outer surface of the internal threaded collar 51. The internal threaded collar 51 can install the dust collector bag 52 at the other end of the external threaded fixing cylinder 1, and at the same time, the dust collector bag 52 and the external threaded fixing cylinder 1 are in a communication state. One end of the dust collector bag 52 has an opening, and a fixed part is embedded inside the opening. The discharge port 53 has a threaded cap 54 on its outer surface, which can seal the discharge port 53. When the fan 3 is controlled by an external switch, the suction generated by the fan 3 can draw away the air inside the building and make it flow, thereby ventilating the building. The air drawn away by the fan 3 will be filtered by the dust collector bag 52 and run to the outside of the building. At this time, the dust will be filtered by the dust collector bag 52 and remain inside the dust collector bag 52. When it is necessary to clean the dust in the dust collector bag 52, the threaded cap 54 can be opened to discharge the dust in the dust collector bag 52.
[0018] The foregoing description, with reference to preferred embodiments, illustrates an exemplary implementation of a ventilation and dust removal device for building decoration provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
