[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Fan is China's customary abbreviation for gas compression and gas delivery machinery. The fans usually mentioned include ventilators, blowers, and wind turbines. Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and air induction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; drying and selection of grains, wind tunnel wind sources and inflation and propulsion of hovercraft, etc.

[0003] Most of the existing fans have single-layer shells and cannot be effectively insulated, which causes the heat to be dissipated into the surrounding environment through the fan shell and the pipe wall when the high-temperature gas is transferred between the conveying pipe and the fan. At the same time, when the existing fans are running, the motor drives the blades to rotate at high speed and the airflow is disturbed, causing the motor to vibrate, which in turn generates a lot of noise. These noises affect the working environment of the operators, thus causing noise pollution. Utility Model Content

[0014] 1. In the utility model, firstly, the branch insulation sleeve is attached to the inside of the shell to insulate the hot air transported inside the shell.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer toFigures 1 - 4 An embodiment provided by the present utility model: a low-noise constant-load insulation fan, including a support platform 1, an outer wall of the support platform 1 is fixedly connected with a housing 2, an insulation component is arranged inside the housing 2, and the insulation component is used for preserving the temperature of the hot air inside the housing 2. A fan 3 is fixedly connected inside the housing 2. An outer wall of the support platform 1 is fixedly connected with a support plate 6. An outer wall of the support platform 1 is slidably connected with a driving motor 5. An output end of the driving motor 5 is fixedly connected inside the fan 3. An outer wall of the support plate 6 is fixedly connected with a base 7. A support column 8 is slidably connected inside the base 7. A bottom of an outer wall of the support column 8 is fixedly connected with a pressing plate 9. An outer wall of the pressing plate 9 is fixedly connected with a limiting rod 10. A first spring 11 is sleeved on an outer wall of the limiting rod 10. An outer wall of the support column 8 is fixedly connected with a slider 12. An outer wall of the slider 12 is fixedly connected with a connecting plate 13. A push rod 14 is fixedly connected inside the connecting plate 13. The push rod 14 is slidably connected with a sleeve 15. A second spring 16 is arranged inside the sleeve 15; the insulation component includes a dendritic insulation sleeve 4, and an outer wall of the dendritic insulation sleeve 4 is fixedly connected inside the housing 2; a top of an outer wall of the support column 8 is fixedly connected with an outer wall of the driving motor 5. One end of the first spring 11 is fixedly connected inside the base 7, and the other end of the first spring 11 is fixedly connected with an outer wall of the pressing plate 9. One end of the second spring 16 is fixedly connected inside the sleeve 15, and the other end of the second spring 16 is fixedly connected with an outer wall of the push rod 14. An outer wall of the sleeve 15 is fixedly connected with an outer wall of the base 7;

[0026] Specifically, when it is necessary to insulate inside the fan while reducing the operating noise, the dendritic insulation sleeve 4 is installed inside the fan housing 2 to ensure that the hot air maintains a stable temperature during operation. Then, the operation of the driving motor 5 not only promotes the normal operation of the fan, but also generates power through shaking and acts on the support column 8, pushing the pressing plate 9 to compress the first spring 11. The limiting rod 10 slides inside the base 7 to effectively control the position of the first spring 11 and ensure uniform pressure distribution. While the support column 8 slides downward, the slider 12 drives the connecting plate 13 to push the push rod 14, and the push rod 14 slides inside the sleeve 15 and compresses the second spring 16. The inside of the sleeve 15 is a sealed space, which effectively reduces the resistance generated by the compression of the internal gas when the first spring 11 and the second spring 16 rebound. This not only improves the insulation effect of the fan, but also significantly reduces the noise level during operation, greatly enhancing the reliability and practicality of the fan in actual applications.

[0027] Refer to Figure 1 、 Figure 5 and Figure 6, a mounting base 17 is fixedly connected inside the outer shell 2. A connecting ring 18 is slidably connected inside the mounting base 17. A protective net 19 is fixedly connected inside the connecting ring 18. A fixing bolt 20 is threadedly connected inside the connecting ring 18. A filter screen 21 is threadedly connected to the outer wall of the fixing bolt 20. A push rod 22 is slidably connected inside the connecting ring 18. One end of the push rod 22 is fixedly connected to a fixing ring 23. A sliding button 27 is fixedly connected to the outer wall of the fixing ring 23. The other end of the push rod 22 is fixedly connected to an insertion plate 24. The outer wall of the insertion plate 24 is slidably connected inside the mounting base 17. A limiting block 25 is fixedly connected to the outer wall of the insertion plate 24. The outer wall of the limiting block 25 is slidably connected inside the connecting ring 18. A third spring 26 is sleeved on the outer wall of the push rod 22. One end of the third spring 26 is fixedly connected inside the connecting ring 18, and the other end of the third spring 26 is fixedly connected to the outer wall of the fixing ring 23.

[0028] Specifically, when it is necessary to filter the airflow inside the suction fan, the protective net 19 is located at the front of the outer shell 2 to block larger impurities and at the same time protect the fan 3 from damage by external objects. At the same time, the filter screen 21 is located inside the outer shell 2 to filter the gas and ensure that the inside of the outer shell 2 remains clean. Then, by sliding the sliding button 27 to drive the fixing ring 23 to compress the third spring 26, and at the same time pulling the insertion plate 24 through the push rod 22, the insertion plate 24 is completely slid out of the inside of the mounting base 17, which enables the protective net 19 and the filter screen 21 to be easily removed for cleaning and replacement, so as to maintain the high-efficiency filtering effect of the gas inside the suction fan. This not only improves the convenience of fan operation but also greatly extends its service life, effectively preventing the influence of dust accumulation and impurities on the fan performance, making the maintenance work more efficient and convenient.

[0029] Working principle: When it is necessary to keep the hot air inside the fan warm and at the same time reduce the noise generated by the operation of the fan, the branch heat preservation sleeve 4 is closely attached to the inside of the outer shell 2, so that when the hot air circulates inside the outer shell 2, the branch heat preservation sleeve 4 can preserve the temperature. When the driving motor 5 is operating, the generated shaking can be converted into the pushing of the support column 8 on the pressing plate 9, so that the pressing plate 9 can continuously compress the first spring 11. The limiting rod 10 slides inside the base 7, so that the limiting rod 10 can limit the position of the first spring 11. When the support column 8 slides downward, the slider 12 will drive the connecting plate 13 to push the push rod 14 at the same time, so that the push rod 14 slides inside the sleeve 15 and can compress the second spring 16 at the same time. Since the inside of the sleeve 15 is a sealed space, when the first spring 11 and the second spring 16 rebound, they will be resisted by the compression of the gas inside the sleeve 15, thereby reducing the rebound, so as to achieve the effect of keeping the temperature inside the fan and reducing the operation noise of the fan, improving the practicability of the fan. When it is necessary to filter the air flow inhaled into the fan, the protective net 19 can block larger impurities and protect the fan 3 at the same time. Then the filter screen 21 can filter the gas inhaled into the inside of the outer shell 2, thereby ensuring the cleanliness inside the outer shell 2. By sliding the sliding button 27 to drive the fixing ring 23 to compress the third spring 26, and at the same time, it can cooperate with the ejector rod 22 to pull the insertion plate 24 until the insertion plate 24 completely slides out of the inside of the mounting seat 17, so that the protective net 19 and the filter screen 21 can be taken out, thus achieving the effect of filtering the gas inhaled into the fan, and at the same time facilitating the disassembly and cleaning of the filter screen 21, improving the convenience of the fan and prolonging the service life of the fan.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
