Detailed Description
The negative pressure type computer ash cleaner consists of a volute body 1, a driving motor 2, a fan impeller 3, a suction nozzle 4, an assembly cylinder 5, a joint 6, a connecting sleeve 7, a nozzle 19 and a jet flow cylinder 9 (see the attached figures 1 and 2 in the specification).
One end of the assembling cylinder 5 is connected with a worm shell 1 in a threaded manner; a fan impeller 3 is arranged in the volute body 1 through a driving motor 2 (see the attached figure 1 of the specification); when the driving motor 2 works, the fan impeller 3 can be driven to synchronously rotate; during the rotation of the fan wheel 3, air can be sucked from the outside, and a high-pressure air flow is formed and sent into the assembly cylinder 5 (see the attached figures 1 and 2 in the specification).
The inlet part of the volute body 1 is provided with an inlet screen 13 (see the attached figure 1 in the specification); the inlet screen 13 can filter the air entering the volute 1 to prevent the dust in the air from entering the fan impeller 3 and affecting the service life of the fan impeller.
The other end of the assembly barrel 5 is sequentially connected with a connector 6, an adapter sleeve 7 and a suction nozzle 4 in a threaded manner (see the attached figures 1 and 2 in the specification).
A jet flow cylinder 9 is fixedly arranged inside the assembly cylinder 5 (see the description attached figure 1); one end of the jet flow cylinder 9 is communicated with the outside through an air outlet flow passage 10 arranged on the assembly cylinder 5. The dust of the negative pressure type computer dust cleaner is finally discharged outside through the air outlet flow channel 10.
An outlet screen 12 (refer to the attached figure 1 in the specification) is arranged on the assembly cylinder 5 outside the air outlet flow channel 10 through a dust collecting cylinder 11. The outlet screen 12 is provided for the purpose of: so that the dust can be collected through the outlet screen 12 after being discharged outside through the air outlet flow channel 10 finally, and the problem that the dust in the computer is adsorbed by the negative pressure type computer dust cleaner and then drifted into the air again to scatter into the computer is avoided.
An expansion hole 16, a mixing straight hole 14 and a diffusion taper hole 15 which are communicated with each other are sequentially arranged in the jet flow cylinder 9 (see the attached figure 2 in the specification); the diffusion taper hole 15 is communicated with the air outlet flow channel 10 (see the attached figure 1 in the specification).
The end of the jet flow cylinder 9 at one side of the expanding hole 16 is provided with a nozzle 19 through a sleeve 17 and a limiting sleeve 18; the nozzle 19 extends to the inside of the expanding hole 16 (see the description of fig. 4); the outlet end of the nozzle 19 is in corresponding relationship with the inlet end of the mixing straight bore 14. When the device works in this way, high-pressure airflow sprayed out of the nozzle 19 can directly enter the mixing straight hole 14 and is finally discharged outside through the diffusion taper hole 15 and the air outlet flow channel 10.
A speed-increasing impeller 8 (see the attached figure 4 in the specification) is fixedly arranged in the nozzle 19 through a pressure ring; the speed-increasing impeller 8 is of an integrated structure and consists of a mounting column 22 and swirl blades 23 (see the attached figure 5 in the specification); the circumferential surface of the mounting column 22 is provided with a spiral swirl vane 23; one end of the mounting post 22 is conical. The purpose of providing the speed-increasing impeller 8 in the nozzle 19 is to: during operation, high-pressure air can uniformly enter between the swirl vanes 23 through the conical surface of the mounting post 22, and the high-pressure air can be ejected from the nozzle 19 in a high-speed "swirl" state under the guidance of the swirl vanes 23.
Two groups of air supply flow passages 21 are symmetrically arranged on the assembly cylinder 5 and the joint 6 (see the attached figure 2 in the specification); one end of the air supply flow passage 21 is communicated with the volute body 1; the other end of the air supply flow passage 21 passes through the sleeve 17 and communicates with the inside thereof (see fig. 2 in the specification). After the arrangement, the high-pressure airflow generated when the fan impeller 3 works can smoothly enter the sleeve 17 through the air supply flow passage 21, and is finally pressurized and accelerated through the nozzle 19 and the accelerating impeller 8 and then is injected into the mixing straight hole 14.
Two groups of air draft flow passages 20 (refer to the attached figures 1 and 3 in the specification) are arranged in the assembly cylinder 5 and the joint 6 in a staggered manner with the air supply flow passage 21; one end of the air draft flow channel 20 is communicated with the expansion hole 16; the other end of the air draft flow channel 20 is communicated with the suction nozzle 4 through a connector 6 and an adapter sleeve 7 (see the attached figures 1 and 4 in the specification); after the arrangement, the dust sucked by the dust remover through the suction nozzle 4 can be discharged outside after passing through the air draft flow channel 20, the expanding hole 16, the mixing straight hole 14 and the diffusion taper hole 15.
When the negative pressure type computer dust remover works, firstly, the driving motor 2 is started to drive the fan impeller 3 to synchronously rotate; when the fan impeller 3 rotates, air can be sucked from the outside, and a high-pressure air flow is formed and sent to the assembly cylinder 5 (see the attached figure 1 in the specification).
The high-pressure air flow entering the fitting cylinder 5 enters the interior of the sleeve 17 through the air supply flow passage 21; finally, the mixture is pressurized and accelerated by a nozzle 19 and a speed-increasing impeller 8 and then is sprayed into the expanding holes 16; the high-pressure airflow entering the expanding hole 16 finally passes through the mixing straight hole 14, the diffusion taper hole 15 and the air outlet flow channel 10 and is discharged outside (see the attached figure 1 in the specification).
In the above process, after the high-pressure airflow is ejected at high speed through the nozzle 19, a relative 'negative pressure zone' can be formed around the nozzle 19; the negative pressure can make the suction nozzle 4 generate certain suction through the air draft flow channel 20 and the connecting sleeve 7. Therefore, when the suction nozzle 4 is aligned to the part needing to be cleaned, under the action of suction force, dust can pass through the connecting sleeve 7 and the air draft flow channel 20 and then is mixed with high-pressure air flow at the expanded hole 16, and finally passes through the mixing straight hole 14 and the diffusion taper hole 15 and then is discharged outside through the air outlet flow channel 10; during the discharge of the high-pressure air flow, the outlet screen 12 filters the high-pressure air flow; therefore, the problem that the cleaned dust is scattered into the air again to pollute the computer again can be prevented.
In the process that the high-pressure airflow enters the diffusion taper holes 15 through the mixing straight holes 14, the space of the diffusion taper holes 15 is suddenly increased, so that the speed of the diffusion taper holes 15 is gradually reduced, and the problem that the outlet screen 12 is broken by 'rushing' when the speed of the high-pressure airflow is too high can be avoided.
The negative pressure type computer dust cleaner has compact structure and smart design; when high-pressure gas passes through the nozzle, the speed of the high-pressure gas can be obviously increased, and the sub-energy can be obviously reduced, so that a relative negative pressure area is formed around the nozzle, a function of suction is generated, and the computer is cleaned. The dust sucked in the way can flow into the dust collecting barrel, so that the dust can be prevented from floating all around and being deposited in other places again, and the problem of low efficiency of the existing computer dust cleaning mode is solved; the use requirement of computer dust cleaning is met.
