Description

Technical Field

[0001] The utility model relates to a fan muffler, and more specifically to a porous honeycomb fan muffler. Background Art

[0002] As an important device widely used in the industrial and construction fields, a fan is mainly used for functions such as ventilation, exhaust, cooling, and air conditioning. However, with the acceleration of the industrialization process and the expansion of the scale of building facilities, the problems of noise and vibration generated by the fan during operation have become increasingly prominent. These noises not only affect the comfort of the factory and office environments, but may also cause disturbances to the surrounding communities, and even have an adverse impact on the long-term operation of the equipment itself.

[0003] Most of the common fan mufflers on the market currently use simple sound-absorbing materials or single-layer structures to reduce noise. Although they can achieve a certain degree of noise reduction effect, their sound absorption ability is limited, especially when facing high-frequency noise, the effect is not ideal. In addition, the existing mufflers generally lack effective shock-absorbing designs and cannot fully absorb the mechanical vibrations generated during the operation of the fan, resulting in the noise still being transmitted through the structure, affecting the overall sound absorption effect.

[0004] In addition, with the enlargement and complexity of fan equipment, the structural design of the existing mufflers is too simple to meet the requirements of various application scenarios and is also relatively difficult to maintain. Once the sound-absorbing materials or structures inside the muffler become aged or damaged, the process of repair and replacement often requires the disassembly of a large number of components, which is time-consuming and laborious, increasing the operation and maintenance costs of the equipment.

[0005] Therefore, aiming at the deficiencies in the existing technology, developing a fan muffler with a reasonable structure, good sound absorption effect, strong shock-absorbing ability and easy to maintain has become an urgent problem to be solved in the current industry Summary of the Utility Model

[0006] In order to solve the above problems, the utility model provides a micro-smoke rotatable moxibustion stick with a reasonable structure and convenient use, whose structure has a rotatable head, a detachable moxibustion head, and a stable fixing mechanism to meet the needs of users.

[0011] The mounting base is located at the lower end of the housing and is fixedly connected to the housing. A buffer assembly is provided between the housing and the mounting base to eliminate the vibration noise generated during the operation of the fan.

[0012] A plurality of second honeycomb plates are provided and are located inside the housing. Each second honeycomb plate is fixedly connected to the inside of the housing through a corresponding buffer ring; it is used to eliminate the noise of the fan; the connection between the second honeycomb plate and the buffer ring is detachable.

[0013] Preferably, the housing is of a cylindrical structure and is hollow inside for accommodating a plurality of second honeycomb plates.

[0014] Preferably, the first honeycomb plate and the housing are fixedly connected by bolts or welding.

[0015] Preferably, the buffer assembly includes a fixing ring, a connecting column and a buffer member; a plurality of fixing rings are fixedly connected to the outside of the housing, a plurality of connecting columns are passed through between the fixing rings, the lower end of the connecting column is fixedly connected to the mounting base, and a plurality of buffer members are installed on the connecting column. Both the buffer member and the connecting column are made of rubber.
