Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of low-noise blowers, and particularly to a new type of low-noise blower. Background Technique
[0002] The blower mainly consists of the following six parts: motor, air filter, blower body, air chamber, base, and oil drip nozzle. The blower operates eccentrically with a rotor offset in the cylinder, and the volume change between the blades in the rotor groove sucks, compresses, and discharges air. During operation, the lubricant is automatically sent to the oil drip nozzle by the pressure difference of the blower and dripped into the cylinder to reduce friction and noise, and at the same time, the gas in the cylinder can be kept from flowing back. Such a blower is also called a sliding vane blower.
[0003] For the existing new type of low-noise blower, reference can be made to the Chinese utility model patent with the authorization publication number CN211398049U, which discloses a low-noise blower unit, "including a blower housing, a driving motor and an impeller are arranged in the blower housing, a blower air inlet and a blower air outlet are arranged on the blower housing, an air flow steadying device is arranged at the blower air inlet, the air flow steadying device includes a plurality of parallel hollow tubes, and the parallel tubes arranged in parallel are connected into an integrated structure. The air flow steadying device is connected to the blower housing through a connecting plate".
[0004] When the above device is in use, the existing device uses the cross-sectional expansion and elongation of the gas passage to guide the gas flow direction, so that the gas passing through the air flow steadying device becomes a relatively stable air flow, which can effectively prevent the formation of eddy currents in the blower, thereby effectively improving the efficiency of the blower and reducing the noise of the blower. However, when the blower outputs gas, the noise will also increase when the gas is too large. Therefore, an effective method is needed to eliminate the noise during gas flow, and during the operation of the blower, the vibration generated by the output of the blower power will cause the installation of the device to become loose. Therefore, a new type of low-noise blower that solves the above problems is needed. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-5, a new type of low-noise blower, comprising a fixed base 1. An anti-seismic arc 2 is provided on the outer wall of the fixed base 1. Connecting holes 3 are formed on the outer wall of the fixed base 1. A connecting wall 4 is fixedly connected to the top of the fixed base 1. A pump housing 5 is installed on the side of the connecting wall 4. A rubber pad 6 is placed on the outer wall of the pump housing 5. A connecting nail 7 is threadedly connected to the inner wall of the connecting wall 4. An electric blower 8 is fixedly installed on the outer wall of the pump housing 5. A junction box 9 is fixedly installed on the top of the electric blower 8. A rear fan cover 10 is formed on the outer wall of the electric blower 8. An air inlet 11 is connected to the outer wall of the pump housing 5. An air outlet 12 is connected to the outer wall of the pump housing 5. A perforated pipe 13 is connected to the outer wall of the air outlet 12. A fiber layer 14 is sleeved on the outer wall of the perforated pipe 13. A silencing cover 15 is fixedly connected to the outer wall of the perforated pipe 13. Through the mutual cooperation of the pump housing 5, rubber pad 6, connecting nail 7, connecting wall 4, fixed base 1, and anti-seismic arc 2 on the device, when the pump housing 5 on the device is connected to the connecting wall 4, first, the rubber pad 6 is used for the interlayer function in the middle, and the pump housing 5 and the connecting wall 4 are connected together by the connecting nail 7, so that a layer of buffering is obtained when the pump housing 5 and the connecting wall 4 on the device are connected. And by means of the anti-seismic arcs 2 provided on both sides of the fixed base 1, when the device is connected to the ground, it has an anti-seismic structure, reducing the vibration transmission of the device and increasing the anti-seismic property.
[0023] In a preferred embodiment, the shape of the anti-seismic arc 2 is arc-shaped, and both sides of the anti-seismic arc 2 are straight plate-shaped. Due to the arc-shaped shape of the anti-seismic arc 2 on the device, the fixed base 1 and the anti-seismic arc 2 on the device cooperate with each other to form an anti-seismic structure. Thus, when the fixed base 1 on the device is installed on the ground by means of the connecting holes 3, the anti-seismic arcs 2 are used for anti-seismic work at both sides of the fixed base 1.
[0024] In a preferred embodiment, the number of the connecting holes 3 is several, and the several connecting holes 3 are arranged on the outer wall of the fixed base 1. Due to the several connecting holes 3 on the device, when the connecting holes 3 on the device are arranged on the outer wall of the fixed base 1, screws are used to pass through the caliber of the connecting holes 3 to be connected to the ground, so that the fixed base 1 on the device can be stably installed on the ground.
[0025] In a preferred embodiment, the outer wall of the air outlet 12 is fitted with the outer wall of the perforated pipe 13, and threaded nails are provided on the inner walls of the air outlet 12 and the perforated pipe 13. Due to the outer wall of the air outlet 12 being fitted with the outer wall of the perforated pipe 13 on the device, the perforated pipe 13 on the device is connected to the air outlet 12 by means of the threaded nails, so that when the air outlet 12 on the device outputs gas, the gas is transmitted into the inner cavity of the perforated pipe 13.
[0026] In a preferred embodiment, through holes are formed in the outer wall of the perforated pipe 13, and a large number of through holes are provided on the outer wall of the perforated pipe 13. By forming through holes in the outer wall of the perforated pipe 13 of the device, a large number of through holes are formed in the perforated pipe 13 of the device. When the perforated pipe 13 conveys gas, the gas will pass over the through holes, so that the gas enters the inner cavity of the fiber layer 14.
[0027] In a preferred embodiment, the fiber layer 14 is made of an inorganic non-metallic material, and the fiber layer 14 is arranged between the perforated pipe 13 and the muffler cover 15. Due to the fact that the fiber layer 14 of the device is made of an inorganic non-metallic material, the fiber layer 14 of the device has the characteristics of good insulation, strong heat resistance and good corrosion resistance. And because the fiber layer 14 is in the inner cavity between the perforated pipe 13 and the muffler cover 15, the gas forms a vortex in the inner cavity of the fiber layer 14, and then the fiber layer 14 is used for sound absorption.
[0028] Working principle: First, through the mutual cooperation of the pump housing 5, rubber pad 6, connecting pins 7, connecting wall 4, fixed base 1 and anti-seismic arc 2 on the device, when the pump housing 5 on the device is connected to the connecting wall 4, first, the rubber pad 6 is used for the interlayer function in the middle, and the connecting pins 7 are used to connect the pump housing 5 and the connecting wall 4 together, so that a layer of buffer is obtained when the pump housing 5 and the connecting wall 4 on the device are connected. And due to the anti-seismic arcs 2 provided on both sides of the fixed base 1, when the device is connected to the ground, it has an anti-seismic structure, reducing the vibration transmission of the device and increasing the anti-seismic performance. Then, through the mutual cooperation of the air outlet 12, perforated pipe 13, fiber layer 14 and muffler cover 15 on the device, when the air outlet 12 on the device outputs gas, the perforated pipe 13 is used for transmission. When the gas passes through the perforated pipe 13, the gas passing through the perforated pipe 13 will form a vortex, and the fiber layer 14 is used for sound absorption, so that the fiber layer 14 on the device silences the transmission noise of the gas between the perforated pipe 13 and the muffler cover 15.
