Description

Technical Field

[0001] The present invention relates to the technical field of electric vacuum cleaners, and particularly to an electric vacuum cleaner capable of plasmaizing dust particles. Background Art

[0002] Existing electrostatic vacuum cleaners charge the inhaled dust particles with positive or negative charges through discharge electrodes, and then the dust collecting electrodes are set with opposite charges. Due to the mutual attraction of positive and negative charges, the dust particles are adsorbed onto the dust collecting electrodes, thereby completing the dust suction operation.

[0003] In some fields of precision manufacturing, such as the manufacturing processes of some precision chips and circuit boards, they are very sensitive to static electricity. During ordinary dust suction, if static electricity discharge occurs, it may damage the internal circuit structures of the chips and circuit boards. Therefore, generally, plasma dust suction can balance the charge distribution on the chip surface by controlling the electric field strength and direction; However, existing plasma electric vacuum cleaners can only fixedly set a single plasma strength and cannot adaptively adjust the plasma strength according to the amount of inhaled dust particles, which leads to the problem of less than ideal dust suction effect during the dust suction process. Summary of the Invention

[0004] The purpose of the present invention is to provide an electric vacuum cleaner capable of plasmaizing dust particles to solve the problems raised in the background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An electric vacuum cleaner capable of plasmaizing dust particles, including an electric vacuum cleaner body, the electric vacuum cleaner body is connected to a dust suction part through a hose, and a butterfly valve and an ion generating part are arranged on the dust suction part; The dust suction part includes a suction nozzle tube, a light scattering dust sensor, and a conducting part. The electric vacuum cleaner body is connected to the conducting part through a hose, the other end of the conducting part is connected to the suction nozzle tube, and a light scattering dust sensor is fixedly installed at the head of the suction nozzle tube; The ion generating part includes an ion generator, a guiding cylinder, and a regulating mechanism. The guiding cylinder is connected to the conducting part, the ion generator is arranged inside the guiding cylinder, the regulating mechanism is arranged outside the guiding cylinder, and the light scattering dust sensor corresponds to the ion generator and the regulating mechanism; Through the cooperation between the dust suction part and the ion generating part, the inhaled dust particles can be plasmaized.

[0006] Further, four groups of the ion generating parts are provided. The conducting part includes a guiding elbow pipe, a guiding straight pipe, and a main dust suction pipe. The main body of the electric dust collector is connected to the main dust suction pipe through a hose. The upper sides of two opposite groups of the ion generating parts are respectively connected to the main dust suction pipe through two groups of the guiding straight pipes. The lower sides of the other two opposite groups of the ion generating parts are respectively connected to the guiding elbow pipe through one group of the guiding straight pipes, and the other end of the guiding elbow pipe is connected to the main dust suction pipe. The lower side of the other group of the ion generating parts is connected to the nozzle pipe through a short pipe. The lower side of the ion generating part opposite to the nozzle pipe is connected to the adjacent guiding straight pipe through one group of the guiding straight pipes and a section of a horizontal pipe; When the amount of dust particles is not enough to be processed by a single ion generating part, close the butterfly valve connecting the two guiding straight pipes on the upper side of the nozzle pipe, and open the butterfly valve connected to another ion generating part, so that after the dust particles are ionized to the strongest degree by the first ion generating part, they enter the second ion generating part for re-ionization treatment. The ionization intensity of the second ion generating part is still adjusted according to the amount of dust particles; then the dust airflow after two-stage ionization flows into the guiding straight pipe on the lower side of the second ion generating part. The butterfly valve here is opened, and the airflow flows into the main dust suction pipe through the connected guiding elbow pipe and finally into the main body of the electric dust collector; A fixing column is fixedly connected to the lower side of the main dust suction pipe, and a connecting frame is fixedly connected to the outer side of the fixing column. The connecting frame is fixed to the conducting part.

[0007] Further, the two guiding straight pipes connected to the upper sides of the two groups of the ion generating parts are respectively connected to one group of the guiding straight pipes on the upper sides of the other two groups of the ion generating parts through a horizontal pipe.

[0008] Further, butterfly valves are fixedly installed between the two guiding straight pipes connected to the upper sides of the two groups of the ion generating parts and the middle of the upper horizontal pipe, and between one group of the guiding straight pipes and the guiding elbow pipe connected to the lower sides of the two opposite groups of the ion generating parts and the middle of the lower horizontal pipe.

[0009] When the amount of dust particles is not enough to be processed by two ion generating parts, close the butterfly valve at the connection between the second ion generating part and the guiding elbow pipe, and open the butterfly valve connected to the third ion generating part, so that after the dust particles are ionized to the strongest degree twice, they enter the third ion generating part. The ionization intensity of the third ion generating part is still adjusted according to the amount of dust particles. Then, for the dust airflow after three-stage ionization, open the upper butterfly valve connected thereto, so that the airflow flows into the main dust suction pipe and finally into the main body of the electric dust collector; Furthermore, the butterfly valve includes a first motor, a valve, and a valve body. A number of valve bodies are fixedly installed on the conducting member. One side of the valve body is fixedly connected to the first motor, and the output end of the first motor is fixedly connected to the valve. The valve corresponds to the notch formed inside the valve body.

[0010] Furthermore, the ion generator includes a circular frame, a positive copper wire mesh, a first terminal, a moving frame, a negative copper tube, a fixed seat, a connecting plate, a connecting column, and a second terminal. A circular frame is arranged inside the guiding cylinder. There are two sets of circular frames. One set of circular frames is fixed to the inside of the guiding cylinder through a mounting block. The positive copper wire mesh is fixedly connected to the inside of this set of circular frames, and the first terminal is fixedly connected to the outside. Uniformly distributed connecting plates and connecting columns are fixedly connected between adjacent circular frames.

[0011] Furthermore, the outside of the connecting column is slidably connected to the moving frame. Uniformly distributed fixed seats are fixedly connected to the side of the moving frame close to the positive copper wire mesh. The negative copper tube is fixedly connected to the inside of the fixed seat. The second terminal is fixedly connected to the connecting plate on the side away from the first terminal. The second terminal is electrically connected to the negative copper tube, and the positive copper wire mesh is electrically connected to the first terminal.

[0012] Low-temperature plasma is generated between the positive copper wire mesh and the negative copper tube, thereby ionizing the inhaled dust particles. Furthermore, the regulating mechanism includes guide rails, a second motor, sliders, a lead screw, fixed blocks, a sliding plate, and a long strip. Two sets of guide rails are fixedly connected to the outside of the guiding cylinder. One end of the guide rail is fixedly connected to the second motor, and the output end of the second motor is fixedly connected to the lead screw. The outside of the lead screw is threadedly connected to the slider. The slider slides on the guide rail. Fixed blocks are fixedly connected to both ends of the guide rail. The inside of the fixed block is connected to the lead screw through a bearing. The long strip is fixedly connected to the side of the slider away from the guide rail. The sliding plate is fixedly connected to the outside of the long strip. The sliding plate slides inside the guiding cylinder. The guiding cylinder is provided with chutes corresponding to the sliding plate and the long strip. The other end of the long strip is fixed to the moving frame.

[0013] The light-scattering dust sensor can detect the amount of inhaled dust particles in real time. Since the light-scattering dust sensor corresponds to the control mechanisms everywhere, when the detected dust particles can be processed only by a single ion generation unit, the second motor is started. The second motor drives the lead screw to rotate. While the lead screw rotates, it drives the slider to slide along the guide rail, so that the slider drives the long block and the slide plate to move, thereby driving the moving frame and the negative copper tube. According to the amount of dust particles, the distance between the negative copper tube and the positive copper wire mesh is controlled. When there are many dust particles, the distance between the negative copper tube and the positive copper wire mesh is close, and thus the generated plasma intensity is high and the power consumption is high. When there are few dust particles, the distance between the negative copper tube and the positive copper wire mesh is far, and thus the generated plasma intensity is weak and the power consumption is low; Further, the ion generation units are pairwise opposite, and adjacent ion generation units are arranged in an inverted manner. The ion generation units can be sequentially connected in series through the conduction member, the short tube, the cross tube, and the butterfly valve.

[0014] When the amount of dust particles cannot be processed by three ion generation units, the upper butterfly valve connected thereto is closed, and the butterfly valve connected to the fourth ion generation unit is opened. Then, after the dust particles are subjected to the strongest plasma ionization three times, they enter the fourth ion generation unit. The intensity of the fourth plasma ionization is still adjusted according to the amount of dust particles. Then, for the dust airflow that has undergone four-stage plasma ionization, the butterfly valve below the fourth ion generation unit is opened, so that the airflow flows into the main dust suction pipe through the guiding elbow pipe, and finally flows into the electric dust collector body.

[0015] Compared with the prior art, the present invention provides an electric dust collector capable of plasma ionizing dust particles, and has the following beneficial effects: 1. For the electric dust collector capable of plasma ionizing dust particles, through the cooperation among the light-scattering dust sensor, the conduction part, and the ion generation unit, when a single ion generation unit is operating, the light-scattering dust sensor can achieve the purpose of detecting the amount of inhaled dust particles in real time, and can adaptively adjust the plasma ionization strength of the single ion generation unit according to the amount of inhaled dust particles, improving the processing effect of plasma ionizing dust particles, and solving the problem that the existing equipment can only fixedly set a single plasma ionization strength and cannot adaptively adjust the plasma ionization strength according to the amount of inhaled dust particles, resulting in an unsatisfactory dust suction effect during the dust suction process.

[0016] 2. For the electric dust collector capable of plasma ionizing dust particles, through the cooperation among the conduction member, the four groups of ion generation units, and the butterfly valve, it can adaptively adjust the plasma ionization treatment of the corresponding stages according to the amount of dust particles, greatly expanding the application range, and at the same time providing an adaptable plasma ionization treatment ability according to the amount of dust particles, avoiding waste of electricity.

The electric vacuum cleaner body 1 is connected to the conducting part through a hose. The other end of the conducting part is connected to the suction nozzle tube 21, and the light-scattering dust sensor 22 is fixedly installed at the head of the suction nozzle tube 21; The ion generation part 4 includes an ion generator 41, a guiding cylinder 42 and a regulating mechanism 43.

The light-scattering dust sensor 22 corresponds to the ion generator 41 and the regulating mechanism 43; Through the cooperation between the dust suction part 2 and the ion generation part 4, the inhaled dust particles can be ionized.

[0021] Furthermore, there are four groups of ion generation parts 4. The conducting part includes a guiding elbow pipe 23, a guiding straight pipe 24 and a dust suction main pipe 25. The electric vacuum cleaner body 1 is connected to the dust suction main pipe 25 through a hose. The upper sides of two opposite groups of ion generation parts 4 are respectively connected to the dust suction main pipe 25 through two guiding straight pipes 24. The lower sides of the other two opposite groups of ion generation parts 4 are respectively connected to the guiding elbow pipe 23 through a guiding straight pipe 24, and the other end of the guiding elbow pipe 23 is connected to the dust suction main pipe 25. The lower side of another group of ion generation parts 4 is connected to the suction nozzle tube 21 through a short pipe. The lower side of the ion generation part 4 opposite to the suction nozzle tube 21 is connected to the adjacent guiding straight pipe 24 through a guiding straight pipe 24 and a section of horizontal pipe; When the amount of dust particles is not enough to be processed by a single ion generation part 4, close the butterfly valve 3 connected to the two guiding straight pipes 24 on the upper side of the suction nozzle tube 21, and open the butterfly valve 3 connected to another ion generation part 4, so that after the dust particles are ionized to the strongest degree by the first ion generation part 4, they enter the second ion generation part 4 for re-ionization treatment. The ionization intensity of the second ion generation part 4 is still adjusted according to the amount of dust particles; then the dust airflow after two-stage ionization flows into the guiding straight pipe 24 on the lower side of the second ion generation part 4. The butterfly valve 3 here is opened, and the airflow flows into the dust suction main pipe 25 through the connected guiding elbow pipe 23 and finally flows into the electric vacuum cleaner body 1; A fixing column 5 is fixedly connected to the lower side of the dust suction main pipe 25, and a connecting frame 6 is fixedly connected to the outside of the fixing column 5. The connecting frame 6 is fixed to the conducting part.

[0022] Furthermore, the two guiding straight pipes 24 connected to the upper sides of the two groups of ion generation parts 4 are respectively connected to a guiding straight pipe 24 on the upper side of the other two groups of ion generation parts 4 through a horizontal pipe.

[0023] Further, butterfly valves 3 are fixedly installed between the two guiding straight pipes 24 that communicate with the upper sides of the two ion generating parts 4 and in the middle of the upper horizontal pipe, and also between the guiding straight pipe 24 and the guiding elbow pipe 23 that communicate with the lower sides of the two opposite ion generating parts 4 and in the middle of the lower horizontal pipe.

[0024] When the amount of dust particles is not enough to be processed by the two ion generating parts 4, close the butterfly valve 3 at the connection between the second ion generating part 4 and the guiding elbow pipe 23, and open the butterfly valve 3 of the ion generating part 4 connected to the third one, so that the dust particles enter the third ion generating part 4 after being subjected to the strongest degree of plasma ionization twice. The intensity of the third plasma ionization is still adjusted according to the amount of dust particles. Then, for the dust airflow that has undergone three - stage plasma ionization, open the upper - side butterfly valve 3 connected thereto, so that the airflow flows into the dust suction main pipe 25 and finally into the electric dust collector body 1. Further, the butterfly valve 3 includes a motor 31, a valve 32, and a valve body 33. A number of valve bodies 33 are fixedly installed on the conducting part. One side of the valve body 33 is fixedly connected to the motor 31, and the output end of the motor 31 is fixedly connected to the valve 32. The valve 32 corresponds to the notch opened inside the valve body 33.

[0025] Further, the ion generator 41 includes a circular frame 411, a positive - electrode copper wire mesh 412, a terminal 413, a moving frame 414, a negative - electrode copper pipe 415, a fixed seat 416, a connecting plate 417, a connecting column 418, and a terminal 419. Inside the guiding cylinder 42, there is a circular frame 411. There are two sets of circular frames 411. Inside the guiding cylinder 42, one set of circular frames 411 is fixed through a mounting block. And inside this set of circular frames 411, there is a fixed - connection positive - electrode copper wire mesh 412, and on the outside, there is a fixed - connection terminal 413. Between adjacent circular frames 411, there are evenly - distributed connecting plates 417 and connecting columns 418 fixedly connected.

[0026] Further, a moving frame 414 is slidably connected to the outside of the connecting column 418. On the side of the moving frame 414 close to the positive - electrode copper wire mesh 412, there are evenly - distributed fixed seats 416 fixedly connected. Inside the fixed seats 416, there is a fixed - connection negative - electrode copper pipe 415. On the connecting plate 417 on the side away from the terminal 413, there is a fixed - connection terminal 419. The terminal 419 is electrically connected to the negative - electrode copper pipe 415, and the positive - electrode copper wire mesh 412 is electrically connected to the terminal 413.

[0027] A low - temperature plasma is generated between the positive - electrode copper wire mesh 412 and the negative - electrode copper pipe 415, thereby ionizing the inhaled dust particles. Further, the regulating mechanism 43 includes a guide rail 431, a second motor 432, a slider 433, a lead screw 434, a fixed block 435, a slide plate 436, and a long strip 437. Two groups of guide rails 431 are fixedly connected to the outer side of the guide cylinder 42. One end of the guide rail 431 is fixedly connected to the second motor 432. The output end of the second motor 432 is fixedly connected to the lead screw 434. The slider 433 is threadedly connected to the outer side of the lead screw 434. The slider 433 slides on the guide rail 431. Both ends of the guide rail 431 are fixedly connected to the fixed block 435. The inner side of the fixed block 435 is connected to the lead screw 434 through a bearing. One side of the slider 433 away from the guide rail 431 is fixedly connected to the long strip 437. The outer side of the long strip 437 is fixedly connected to the slide plate 436. The slide plate 436 slides inside the guide cylinder 42. The guide cylinder 42 is provided with a chute corresponding to the slide plate 436 and the long strip 437. The other end of the long strip 437 is fixed to the moving frame 414.

[0028] The light scattering dust sensor 22 can detect the amount of inhaled dust particles in real time. Since the light scattering dust sensor 22 corresponds to the regulating mechanisms 43 at various places, when the detected dust particles can be processed only by a single ion generating part 4, the second motor 432 is started. The second motor 432 drives the lead screw 434 to rotate. While the lead screw 434 is rotating, it drives the slider 433 to slide along the guide rail 431, so that the slider 433 drives the long strip 437 and the slide plate 436 to move, thereby driving the moving frame 414 and the negative copper tube 415. According to the amount of dust particles, the distance between the negative copper tube 415 and the positive copper wire mesh 412 is further controlled. When there are many dust particles, the distance between the negative copper tube 415 and the positive copper wire mesh 412 is close, and thus the generated plasma intensity is high and the power consumption is high. When there are few dust particles, the distance between the negative copper tube 415 and the positive copper wire mesh 412 is far, and thus the generated plasma intensity is weak and the power consumption is low. Further, the ion generating parts 4 are arranged in pairs opposite to each other, and the adjacent ion generating parts 4 are arranged in an inverted manner. The ion generating parts 4 can be sequentially connected in series through a conducting member, a short tube, a cross tube, and a butterfly valve 3.

[0029] When the amount of dust particles cannot be processed by three ion generating parts 4, the upper butterfly valve 3 connected thereto is closed, and the butterfly valve 3 connected to the fourth ion generating part 4 is opened. Then, after the dust particles are subjected to the strongest degree of plasma ionization three times, they enter the fourth ion generating part 4. The intensity of the fourth plasma ionization is still adjusted according to the amount of dust particles. Then, for the dust airflow that has undergone four-stage plasma ionization, the butterfly valve 3 below the fourth ion generating part 4 is opened, so that the airflow flows into the dust suction main pipe 25 through the guiding elbow 23 and finally flows into the electric dust collector body 1.

[0030] The specific usage method and function of this embodiment: During use, first fix this device to the production line of the precision manufacturing dust removal workshop. The dust suction head of this device can be fixedly installed with an external manipulator, and the external manipulator drives the dust suction head to perform dust suction operations on the precision workpiece chips and circuit boards on the production line; When performing dust suction operations on precision workpieces, start the electric dust collector body 1. The electric dust collector body 1 sucks air through the fan inside it into the hose connected to the dust suction main pipe 25. At this time, start the butterfly valve 3 connected to the two groups of guiding straight pipes 24 on the upper side of the suction nozzle pipe 21, so that the motor 31 drives the valve 32 to rotate, and the notch inside the valve body 33 opens, thereby generating suction inside the suction nozzle pipe 21, and sucking the dust on the precision parts through the suction force; Since the positive copper wire mesh 412 and the negative copper pipe 415 are respectively connected to the first terminal 413 and the second terminal 419 through wires, and then an external power supply is connected to the first terminal 413 and the second terminal 419 through wires, current is passed through the positive copper wire mesh 412 and the negative copper pipe 415. At this time, only the ion generation part 4 connected to the suction nozzle pipe 21 is passed through with current, and then a low-temperature plasma is generated between the positive copper wire mesh 412 and the negative copper pipe 415, thereby ionizing the inhaled dust particles; Since the head of the suction nozzle pipe 21 is provided with a light scattering dust sensor 22, the light scattering dust sensor 22 can detect the amount of inhaled dust particles in real time. Since the light scattering dust sensor 22 corresponds to the control mechanisms 43 everywhere, when it is detected that the inhaled dust particles can be processed only by a single ion generation part 4, start the motor 432. The motor 432 drives the lead screw 434 to rotate. While the lead screw 434 rotates, it drives the slider 433 to slide along the guide rail 431, so that the slider 433 drives the long block 437 and the slide plate 436 to move, thereby driving the moving frame 414 and the negative copper pipe 415. According to the amount of dust particles, the distance between the negative copper pipe 415 and the positive copper wire mesh 412 is controlled. When there are many dust particles, the distance between the negative copper pipe 415 and the positive copper wire mesh 412 is close, and thus the generated plasma intensity is high and the power consumption is high. When there are few dust particles, the distance between the negative copper pipe 415 and the positive copper wire mesh 412 is far, and thus the generated plasma intensity is weak and the power consumption is low; When the amount of dust particles is insufficient to be processed by a single ion generation unit 4, the butterfly valve 3 communicating with the two groups of guiding straight pipes 24 on the upper side of the nozzle pipe 21 is closed, and the butterfly valve 3 communicating with another ion generation unit 4 is opened. So that after the dust particles are ionized to the strongest degree by the first ion generation unit 4, they enter the second ion generation unit 4 for re-ionization treatment. The ionization intensity of the second ion generation unit 4 is still adjusted according to the amount of dust particles. Then, the dust airflow after two-stage ionization flows into the guiding straight pipe 24 under the second ion generation unit 4. The butterfly valve 3 here is opened, and the airflow flows into the dust suction main pipe 25 through the communicating guiding elbow pipe 23, and finally flows into the electric vacuum cleaner body 1. When the amount of dust particles is insufficient to be processed by two ion generation units 4, the butterfly valve 3 at the connection between the second ion generation unit 4 and the guiding elbow pipe 23 is closed, and the butterfly valve 3 communicating with the third connected ion generation unit 4 is opened. So that after the dust particles are ionized to the strongest degree twice, they enter the third ion generation unit 4. The ionization intensity of the third ionization is still adjusted according to the amount of dust particles. Then, for the dust airflow after three-stage ionization, the upper butterfly valve 3 connected thereto is opened, so that the airflow flows into the dust suction main pipe 25, and finally flows into the electric vacuum cleaner body 1. When the amount of dust particles is insufficient to be processed by three ion generation units 4, the upper butterfly valve 3 connected thereto is closed, and the butterfly valve 3 communicating with the fourth ion generation unit 4 is opened. Then, after the dust particles are ionized to the strongest degree three times, they enter the fourth ion generation unit 4. The ionization intensity of the fourth ionization is still adjusted according to the amount of dust particles. Then, for the dust airflow after four-stage ionization, the butterfly valve 3 under the fourth ion generation unit 4 is opened, so that the airflow flows into the dust suction main pipe 25 through the guiding elbow pipe 23, and finally flows into the electric vacuum cleaner body 1. Up to four-stage ionization treatment can be achieved to meet the requirements of different dust amounts.
