Description

Technical Field

[0001] This utility model relates to the field of silent compressors, and in particular to a silent compressor. Background Technology

[0002] Nebulizers are playing an increasingly important role in medical settings, hospital wards, and everyday home use. However, patients and their families are also raising their expectations for nebulizers. They want them to operate quietly, without making loud noise, so as not to interfere with rest and treatment effectiveness. With the growing demand for quiet nebulizers, quiet operation has become a key selling point.

[0003] The compressor, the core component of an atomizer, needs to operate continuously for extended periods. In some cases, it may need to run for several hours or even longer each day. This necessitates that the compressor possess extremely high durability to ensure that the atomizer does not frequently malfunction during long-term use. This, in turn, reduces operating costs and maintenance workload.

[0004] Currently, traditional compressors on the market suffer from problems such as high noise levels and insufficient durability. These issues not only affect the efficiency of industrial production but also have adverse environmental impacts. To meet the urgent market demand, there is a need for a silent compressor that incorporates various noise-reducing designs in multiple noise-generating areas, thereby reducing overall compressor noise during operation to meet users' needs for use at night or in low-noise environments. Utility Model Content

[0005] The main purpose of this utility model is to provide a silent compressor that employs various quieting designs in multiple noise-generating locations, thereby reducing the overall noise during compressor operation to meet the user's needs for use at night or in low-noise environments.

[0006] This utility model proposes a silent compressor, including a motor, an air pump and a cooling fan blade. The motor and the air pump are fixedly connected. One end of the output shaft of the motor is connected to the connecting rod of the air pump through a connector, so that the air pump can be driven by the motor. The other end of the output shaft of the motor is connected to the cooling fan blade.

[0007] The cooling fan blade includes a fan blade body, an outer fan blade baffle disposed in the middle of the outer side of the fan blade body, and an inner fan blade baffle disposed in a ring on the inner side of the fan blade body. By providing the outer fan blade baffle and the inner fan blade baffle, the noise of the cooling fan blade can be reduced.

[0008] The air pump includes an air pump housing. An air inlet and an air outlet are provided at the bottom of the air pump housing. An air plug is provided in the air inlet and the air outlet. A spiral air groove is provided on the side of the air plug. By cooperating with the air inlet and the air outlet, the length of the air inlet and the air outlet in the air inlet and the air outlet in the air outlet and the air outlet in the air outlet and the air inlet can be extended, and multiple bends can be formed in the air outlet and the air inlet, thereby reducing the internal noise of the air pump housing.

[0009] The air pump housing is provided with an air outlet chamber and an expansion-type air inlet chamber. An air outlet column is provided in the middle of the air inlet chamber, and an air outlet hole is provided at the top of the air outlet column. An air outlet plug is provided on the top cover of the air outlet hole. Multiple air inlet holes are provided on the side of the air outlet column. By setting up an expansion-type air inlet chamber, the noise generated when the air pump draws air can be reduced.

[0010] Preferably, it also includes a silent housing, which covers the connection between the motor and the air pump. The silent housing can reduce the noise when the output shaft drives the connecting rod of the air pump through the connector.

[0011] Preferably, the connecting element is an eccentric wheel.

[0012] Preferably, the motor is a shaded-pole motor, which includes a motor housing, a main winding, an auxiliary winding, and a rotor. The main winding is wound on one side of the motor housing, the auxiliary winding is disposed on the other side of the motor housing, and the rotor is disposed in the middle of the auxiliary winding. The motor housing includes a motor housing body and a first connecting bracket and a second connecting bracket disposed on both sides of the motor housing body. The first connecting bracket and the second connecting bracket are respectively fixedly connected to the motor housing body and limit the rotor to be disposed within the motor housing body.

[0013] Preferably, the output shaft of the motor is fixedly connected to the rotor, and a first connecting bearing and a second connecting bearing are respectively provided between the first connecting bracket and the second connecting bracket and the output shaft of the motor.

[0014] Preferably, a force-bearing steel sleeve is provided on the outer side of the second connecting bearing, and an annular thin pad is provided between the second connecting bearing, the force-bearing steel sleeve and the second connecting bracket. By providing the thin pad, the noise generated during the rotation of the motor's output shaft can be reduced.

[0015] The beneficial effects of the silent compressor of this utility model are as follows:

[0016] 1. By setting up cooling fan blades with a silent design, by setting air plugs with spiral air grooves in the air inlet and outlet, by setting up a silent housing, and by setting up an expansion-type air inlet chamber, the overall noise can be reduced by reducing the quietness of each component of the air pump motor.

[0017] 2. By setting an annular thin pad between the second connecting bearing and the power steel sleeve and the second connecting bracket, the noise generated during the rotation of the motor output shaft can be reduced without affecting the smoothness of the motor output shaft rotation.
