[0002] Indoor air circulation is an important environmental regulation process, which is mainly realized through specific ventilation systems and air regeneration systems. In a closed or semi-closed space, indoor air circulation can continuously update and flow, thereby significantly improving the quality of indoor air while reducing energy consumption. This process usually involves air filtration, purification, and temperature and humidity regulation. Through an efficient filtration system, dust, bacteria, and other harmful substances in the air can be removed, ensuring the cleanliness of indoor air. At the same time, the air regeneration system can adjust the humidity and temperature of the air to achieve a comfortable range. Indoor air circulation not only helps to improve the comfort of occupants but also effectively prevents the spread of diseases. By maintaining the circulation and freshness of indoor air, the survival rate of viruses and bacteria in the indoor environment can be reduced, thereby protecting people's health. In summary, indoor air circulation is an efficient and environmentally friendly indoor environmental regulation method that can improve the living experience while promoting people's health.

DETAILED DESCRIPTION

[0022] The utility model will be described in detail below in combination with the drawings.

[0023] For example, Figs. 1-3As shown, a ventilated blower includes a body 1 and an air inlet 11 and an air outlet 12 arranged on the body 1, the air inlet 11 is connected with an air inlet pipe 13, the air inlet pipe 13 includes a first pipe 14 installed on the air inlet 11 and a second pipe 18 connected with the first pipe 14, the outer wall of the first pipe 14 is formed with a semi-encircling groove 15, and the inner end of the second pipe 18 is formed with a connecting port 16 matched with the semi-encircling groove 15; the side wall and the end face of the semi-encircling groove 15 are respectively pasted with a sound-absorbing layer 17 made of cotton material; the two side walls in the second pipe 18 are installed with sound-absorbing modules 3, and the sound-absorbing modules 3 can be taken out from the second pipe 18 in a detachable manner.

[0024] The side wall and the end face of the semi-encircling groove 15 of the first pipe 14 are pasted with the sound-absorbing layer 17 made of cotton material, the cotton material has good sound-absorbing characteristics, can absorb high-frequency noise generated by air flow and blower operation through a porous structure, and the structure design of the semi-encircling groove 15 increases the contact area of the sound-absorbing layer 17 with the airflow, further enhancing the noise reduction effect. The sound-absorbing modules 3 installed on the two side walls in the second pipe 18 can absorb noise in different directions in the pipe, forming a double noise reduction structure with the sound-absorbing layer 17 of the first pipe 14, reducing the spread of noise from the air inlet source to the outside, and improving the quietness of the equipment operation. The sound-absorbing modules 3 in the second pipe 18 adopt a detachable design, which can be directly taken out from the pipe without disassembling the whole pipe, facilitating regular cleaning, inspection or replacement of the aging sound-absorbing modules 3, solving the problem of complex process of disassembling the air duct during maintenance of the traditional welded structure. The sound-absorbing layer 17 of the first pipe 14 is fixed by pasting, compared with the welded connection of the sound-absorbing structure, when the sound-absorbing layer 17 is worn or aged, the old layer can be directly peeled off and a new layer can be pasted, simplifying the maintenance operation and reducing the maintenance time and labor cost.

[0025] The first pipe 14 is formed with a first air inlet 11, the first air inlet 11 is sleeved with a guide frame 2, the inner end of the second pipe 18 is protrusively formed with an air inlet guide port 21 matched with the first air inlet 11, and the air inlet guide port 21 is inserted into the guide frame 2. The first air inlet 11 of the first pipe 14 is sleeved with the guide frame 2, the air inlet guide port 21 at the inner end of the second pipe 18 is matched with the first air inlet 11 and is inserted into the guide frame 2, forming a double guide structure. The guide frame 2 provides a precise insertion track for the air inlet guide port 21, avoiding the assembly jam caused by alignment deviation when the two pipes are connected. The air inlet guide port 21 is inserted into the guide frame 2, and the close fit of the two forms a barrier at the pipe connection, effectively blocking the air leakage from the connection gap. The guide positioning structure makes the two pipes not easy to produce relative displacement during operation, avoiding the increase of the gap caused by loosening at the connection position.

[0026] Further, the semi-enclosed groove 15 is formed with a plurality of outer connecting holes 22, and the outer side wall of the second pipeline 18 is formed with inner connecting holes 23 coaxially aligned with the outer connecting holes 22, and a disassembly screw is arranged between the outer connecting holes 22 and the inner connecting holes 23. The outer connecting holes 22 of the semi-enclosed groove 15 are coaxially aligned with the inner connecting holes 23 of the outer side wall of the second pipeline 18, and are fixed by the disassembly screw, forming a stable rigid connection structure; the disassembly screw connection is used instead of welding, retaining the disassembly of the connection structure. When the sound-absorbing layer 17 or the sound-absorbing module 3 inside the pipeline needs to be maintained, only the disassembly screw needs to be unscrewed to separate the first pipeline 14 and the second pipeline 18, which is simple and convenient to operate, without the need for professional welding tools and technology, reducing the threshold and cost of maintenance.

[0027] Further, the outer side wall of the second pipeline 18 is provided with a rubber plate 24, and the rubber plate 24 cooperates with the semi-enclosed groove 15. The rubber plate 24 has good elasticity and sealing performance, and when the second pipeline 18 is connected with the first pipeline 14, the rubber plate 24 tightly fits the semi-enclosed groove 15. The rubber plate 24 will deform due to extrusion, thereby filling the small gap between the semi-enclosed groove 15 and the outer side wall of the second pipeline 18, forming an additional sealing barrier. The blower will vibrate when it is running, and this vibration will be transmitted through the pipeline connection part. The rubber plate 24 has certain elasticity and damping properties, and when the pipeline vibrates, the rubber plate 24 can absorb and buffer part of the vibration energy, reducing the transmission of vibration between the first pipeline 14 and the second pipeline 18.

[0028] The inner and outer ends of the second pipeline 18 are formed with an outer end air inlet 25, and the two sides of the outer end air inlet 25 are respectively formed with sound-absorbing installation grooves 26 for inserting the sound-absorbing module 3. The sound-absorbing module 3 is installed into the second pipeline 18 through the sound-absorbing installation grooves 26, and tightly fits the inner wall of the second pipeline 18, achieving the noise reduction requirement.

[0029] The sound-absorbing module 3 includes a sound-absorbing plate 31 made of polyester fiber. The sound-absorbing plate 31 made of polyester fiber has a loose and porous structure, which can effectively absorb the low-frequency noise generated when the airflow passes through the pipeline. The surface of the sound-absorbing plate 31 is formed with a plurality of sound-absorbing holes 34, which are distributed in a honeycomb shape. The depth of the honeycomb holes is designed to guide the noise into the holes and then undergo multiple reflections and friction to convert it into heat energy, thereby enhancing the absorption of high-frequency noise. The outer end of the sound-absorbing plate 31 is provided with an outer stop bar 32 that cooperates with the sound-absorbing installation groove 26. The outer stop bar 32 at the outer end of the sound-absorbing plate 31 cooperates with the sound-absorbing installation groove 26 in the second pipeline 18 to precisely limit the installation position of the sound-absorbing module 3 in the pipeline, preventing displacement of the module due to airflow impact or pipeline vibration. The outer stop bar 32 is provided with a pulling handle 33. The pulling handle 33 installed on the outer stop bar 32 provides a convenient force point for disassembling the sound-absorbing module 3.

[0030] Further, the inner end of the sound absorption plate 31 is provided with a guide strip 35, the guide strip 35 is formed with an inner locking hole 36 along the length direction, the top of the second pipeline 18 is formed with an outer locking hole 37 matched with the inner locking hole 36, and the outer locking hole 37 is detachably inserted with a locking rod 38. The guide strip 35 mounted at the inner end of the sound absorption plate 31 can slide along the preset track inside the pipeline during the process of inserting the sound absorption module 3 into the second pipeline 18, thereby providing stable guiding for the module. The inner locking hole 36 on the guide strip 35 is matched with the outer locking hole 37 at the top of the second pipeline 18, and the locking rod 38 is detachably inserted thereinto, thereby forming a reliable locking structure. The locking rod 38 is designed to be detachable, and when the sound absorption module 3 needs to be maintained or replaced, the locking rod 38 is only needed to be pulled out to release the locking state, and the module can be easily taken out by cooperating with the pulling handle 33, the operation process is simple and efficient, without the need of complex tools or professional skills, thereby further reducing the maintenance threshold.
