Ultra-high pressure vacuum cleaner motor

Abstract

The present invention discloses an ultra-high pressure vacuum cleaner motor, comprising an aluminum alloy shell and a wind cover and a rear cover arranged on the front and rear sides of the aluminum alloy shell. In the ultra-high pressure vacuum cleaner motor of the present invention, during the operation of the vacuum cleaner motor, the Tesla valve principle formed between the first air duct groove and each group of second air duct grooves is used to amplify the air pressure after input by multiple times, while the air pressure at the input end of the fan blade remains unchanged, so that the vacuum cleaner motor can be used in an ultra-high pressure state and the fan blade can be prevented from exploding due to excessive pressure, which is convenient for efficient operation and use of the vacuum cleaner motor. Moreover, through the Tesla valve principle formed between the first air duct groove and each group of second air duct grooves, the wind pressure at the air inlet has the least resistance when passing through the air duct. On the contrary, the airflow at the output port has the greatest resistance when it flows back under the action of pressure, thereby achieving the effect of supporting and amplifying the low input air pressure to form a high output air pressure.

After being arranged in a ring shape, each group of arc plates 202 is provided with a circulation component for pressure control;

[0022] The circulation component includes a first air duct groove 301 opened on the arc plate 202, and a plurality of second air duct grooves 302 are connected to the first air duct groove 301, and the shape between the first air duct groove 301 and the plurality of second air duct grooves 302 is arranged in a Tesla valve shape;

[0023] It should be noted here that during the operation of the vacuum cleaner motor, the input air pressure is amplified many times through the Tesla valve principle formed between the first air duct groove 301 and each group of second air duct grooves 302, while the air pressure at the input end of the fan blade 105 remains unchanged, so that the vacuum cleaner motor can be used in an ultra-high pressure state and the fan blade 105 can be prevented from exploding due to excessive pressure, which is convenient for efficient operation and use of the vacuum cleaner motor. In addition, through the Tesla valve principle formed between the first air duct groove 301 and each group of second air duct grooves 302, the wind pressure at the air inlet has the smallest resistance when passing through the air duct. On the contrary, the airflow at the output port has the largest resistance when it flows back under the action of pressure, thereby achieving the effect of supporting and amplifying the low input air pressure to form a high output air pressure.

[0024] After two adjacent sets of arc-shaped plates 202 are installed and connected, the two sets of circulation components are arranged in a state of end-to-end communication;

[0025] It should be noted here that the flow components on two adjacent groups of arc-shaped plates 202 are connected to facilitate the flow and transportation of gas.

[0026] The connection assembly includes a T-shaped slide groove 402 provided on the outer side wall of the air duct support 201, and a T-shaped slider 401 matched with the T-shaped slide groove 402 is fixed on the inner side of the arc plate 202;

[0027] It should be noted here that: the T-shaped groove 402 and the T-shaped slider 401 facilitate the insertion and installation of the arc plate 202 on the outside of the air duct bracket 201.

[0028] A positioning plate 403 is fixed to the inner side of the arc plate 202 for positioning the arc plate 202 after being inserted and connected to the outer side of the air duct support 201;

[0029] It should be noted here that: the arc plate 202 is inserted and installed on the air duct support 201 to be positioned against each other through the positioning plate 403 .

[0030] The installation assembly includes a threaded rod 501 fixed to the end of the shaft core 104, and a first gasket 502 and a second gasket 503 are respectively provided on the front and rear sides of the fan blade 105, and the fan blade 105, the first gasket 502 and the second gasket 503 are sleeved and installed on the threaded rod 501 and are restrained by a nut 504;

[0032] Working principle: During the operation of the vacuum cleaner motor, the stator 107 on the vacuum cleaner motor is energized through power control and transmission. The stator 107 after being energized acts electromagnetically with the magnet on the shaft core 104 to drive the shaft core 104 to rotate. During the rotation of the shaft core 104, the fan blade 105 is driven to rotate through the installation connection of the installation assembly.

[0033] During the rotation of the fan blade 105, the external wind pressure is sucked into the interior of the vacuum cleaner motor and circulates on the first air duct groove 301 and the second air duct groove 302 on each group of arc plates 202. During the circulation process, the input air pressure is amplified many times through the Tesla valve principle formed between the first air duct groove 301 and each group of second air duct grooves 302, while the air pressure at the input end of the fan blade 105 remains unchanged, so that the vacuum cleaner motor can be used in an ultra-high pressure state and the fan blade 105 can be prevented from exploding due to excessive pressure, which is convenient for efficient operation and use of the vacuum cleaner motor. In addition, through the Tesla valve principle formed between the first air duct groove 301 and each group of second air duct grooves 302, the wind pressure at the air inlet has the smallest resistance when passing through the air duct. On the contrary, the airflow at the output port has the largest resistance when it flows back under the action of pressure, thereby achieving the effect of supporting and amplifying the low input air pressure to form a high output air pressure.
