Description

Technical Field

[0001] The invention relates to the technical field of electrostatic dust collection, in particular to an electric dust collector with uniform discharge. Background Art

[0002] An electrostatic vacuum cleaner is a device that uses a high voltage electric field to ionize gas, thereby charging dust particles and trapping them on the vacuum cleaner. Its working principle mainly includes the processes of corona discharge, charging of dust particles, movement of dust particles to the electrode, and removal of dust particles.

[0003] The structure of most electrostatic vacuum cleaners currently on the market is to perform electrostatic dust removal operations mainly through the cooperation of an electrode rod and an outer dust collection barrel. However, the negative pressure mechanism in the vacuum cleaner draws the dust-carrying air from the outside from the electrode rod and the lower side of the dust collection barrel to the upper side. Therefore, the flow rate of the air flowing through the electrode rod and the dust collection barrel gradually decreases from bottom to top, and then the dust distribution amount gradually decreases from bottom to top. The existing electrostatic vacuum cleaner only discharges through a single electrode rod, and is unable to discharge evenly according to the dust distribution amount, which results in its dust removal effect being less than ideal. Summary of the invention

[0004] The object of the present invention is to provide an electric vacuum cleaner with uniform discharge to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an electric vacuum cleaner with uniform discharge, comprising a frame, a negative pressure mechanism is fixedly installed on one side of the frame, an electrostatic dust suction mechanism is fixedly installed on the upper side of the base of the frame, and a collecting assembly is arranged on the inner side of the bottom of the electrostatic dust suction mechanism.

[0006] The electrostatic dust suction mechanism includes a dust collection cylinder, a rotating component, an electrode rod, a striking component, and a magnetic component. The dust collection cylinder is fixedly connected to the upper side of the base of the frame, and a rotating component is arranged on the inner side of the upper part of the frame. The electrode rod is fixedly connected to the inner side of the dust collection cylinder and on the lower side of the rotating component through a rectangular plate. The magnetic component is fixedly connected to the outer side of the rotating component and on the inner side of the dust collection cylinder, and a striking component is arranged on the outer side of the lower part of the magnetic component.

[0007] The electrode rod is fixedly mounted with an electrode sheet, the density of the electrode sheet gradually decreases from bottom to top, and a dust removal cylinder is arranged on the outer side of the electrode rod, and the dust removal cylinder is located on the inner side of the vehicle frame.

[0008] The electrode rods and the electrode sheets can be used to match the corresponding dust amounts, so that discharge can be uniform.

[0009] Furthermore, the negative pressure mechanism includes a negative pressure box, a guide cylinder, a filter plate, and a fan. The negative pressure box is fixedly connected to one side of the frame, the fan is fixedly connected to the inner bottom side of the negative pressure box, the upper side of the fan is connected to the guide cylinder, the inner side of the guide cylinder is fixedly connected to the filter plate, the guide cylinder is provided in two groups, and the upper side of the guide cylinder is connected to the upper part of the dust collection cylinder through a hose.

[0010] Furthermore, the rotating assembly includes a fixed cover, a bearing shell, a fixed ring, a bearing, a connecting shaft, and an impeller. The upper side of the dust collector cylinder is fixedly connected with the fixed cover, and a bearing shell is provided on the inner side of the upper part of the dust collector cylinder. The fixed cover is fixedly connected to the fixed cover by screws, a bearing is installed on the inner side of the bearing shell, and a connecting shaft is fixedly connected to the inner side of the bearing. The lower side of the connecting shaft is fixedly connected with the impeller, and the upper side of the impeller is fixedly connected with the fixed ring.

[0011] Furthermore, the magnetic assembly includes a fixed block, a connecting block, and a magnetic block. The upper side of the fixed ring is fixedly connected with a uniformly distributed fixed block, the lower side of the fixed block is fixedly connected with a connecting block, the outer side of the connecting block is fixedly connected with an annular rotating block, the inner and outer sides of the annular rotating block are both provided with annular tracks, the outer annular track is fixedly connected to the inner wall of the dust collection cylinder, the inner annular track is fixedly connected to the outer wall of the dust collection cylinder, the annular rotating block rotates between the inner and outer annular tracks, and the lower side of the connecting block is fixedly connected with a magnetic block.

[0012] While electrostatic dust removal is being carried out, the airflow drives the rotating component to rotate. While the rotating component is rotating, the fixed ring, the fixed block and the connecting block are connected to mobilize the magnetic block to rotate in a circle. While the connecting block is rotating, it drives the annular rotating block to rotate in the inner and outer annular orbits, so that a rotating magnetic field is applied to the outside of the dust collector. The rotating magnetic field force drives the electrons to rotate in a circle, thereby achieving uniform distribution of electrons inside the dust collector and further uniform dust removal.

[0013] Furthermore, the striking assembly includes a pushing rod, a force plate, a striking block, a mounting seat, a fixed shaft, and a torsion spring. The outer side of the lower part of the dust removal cylinder is fixedly connected with an evenly distributed mounting seat, the inner side of the mounting seat is provided with a fixed shaft, the outer side of the fixed shaft is fixedly connected with a torsion spring and a force plate, a striking block is fixedly connected between the fixed shaft and the inner side wall of the mounting seat, and a pushing rod is fixedly installed on the lower part of the magnetic block, and the pushing rod corresponds to the force plate.

[0014] While the magnetic block is rotating in a circle, the push rod on it intermittently pushes the force plate, and the force plate drives the torsion spring and the fixed shaft to rotate intermittently, thereby compressing the striking block. When the push rod is separated from the force plate, the spring force of the striking block drives the torsion spring to strike the dust collector, thereby vibrating the dust adsorbed inside the dust collector down, and the dust box collects the dust, and the staff regularly pulls out the dust box for cleaning.

[0015] Furthermore, the collection assembly includes a dust box and a dust gun. The dust box is clamped on the inner side of the bottom of the dust cylinder, a T-shaped block is fixedly connected to the outer side of the dust box, a sliding groove corresponding to the T-shaped block is opened on the inner side of the dust cylinder, and the outer side of the dust box is connected to the dust gun.

[0016] The device is pushed to the area to be vacuumed and dust removed. The staff holds the vacuum gun and scans the area to be vacuumed and dust removed. At the same time, the fan is started, which generates wind. The wind direction is from the guide tube to the direction of the fan. Then, through the guiding effect of the guide tube and the hose, the wind force sucks the air mixed with dust and impurities from the vacuum gun, first enters the upper part of the dust box, and then moves upward.

[0017] Furthermore, the electrode sheet is a spherical electrode sheet, and the spherical electrode sheet is fixed to the electrode rod by screws.

[0018] Furthermore, the electrode sheet is a cylindrical electrode sheet, and the cylindrical electrode sheet is fixed to the electrode rod by screws.

[0019] Furthermore, the electrode sheets are mesh electrode sheets, which are fixedly connected to the electrode rods and are distributed in a ring array outside the electrode rods.

[0020] A high voltage current is passed through the electrode rod (discharge electrode, negative electrode). Since the electrode rod is electrically connected to the dust collector (dust collecting electrode, positive electrode), under the action of the high voltage electric field, the gas molecules in the airflow are ionized into positive ions and electrons, and these ions and electrons move toward the two poles under the action of the electric field force.

[0021] The charged dust is separated from the airflow under the action of the electric field force, and the negatively charged dust particles move toward the dust collector, where they are adsorbed on the inside by the electrostatic force.

[0022] Since the electrode rod is provided with electrode sheets whose density gradually decreases from bottom to top, the electrode sheets may be spherical electrode sheets, cylindrical electrode sheets or mesh electrode sheets. Since the dust distribution amount gradually decreases from bottom to top, the dust distribution amount corresponds to the density of the electrode sheets, and then uniform discharge can be performed according to the distribution of the dust distribution amount, thereby improving the electrostatic dust removal capacity.

[0023] Compared with the prior art, the present invention provides an electric vacuum cleaner with uniform discharge, which has the following beneficial effects:

[0024] 1. The electric vacuum cleaner with uniform discharge is provided with electrode sheets whose density gradually decreases from bottom to top on the electrode rod 33. The electrode sheets can be spherical electrode sheets, cylindrical electrode sheets or mesh electrode sheets, and the dust distribution amount gradually decreases from bottom to top, so that the dust distribution amount corresponds to the density of the electrode sheets, and then the discharge can be uniformly performed according to the distribution of the dust distribution amount, thereby improving the electrostatic dust removal ability, thereby changing the existing single electrode rod discharge mode, and solving the problem that the discharge cannot be uniformly performed according to the dust distribution amount, thereby causing the dust removal effect to be less than ideal.

[0025] 2. The electric vacuum cleaner with uniform discharge can apply a rotating magnetic field on the outside of the electrostatic dust collector through the cooperation between the negative pressure mechanism, the rotating component, the magnetic component, and the striking component. The rotating magnetic field force drives the electrons to rotate in a circle, thereby achieving uniform distribution of electrons inside the dust collector, further uniformly removing dust, and improving the dust collection and removal effect. At the same time, while rotating, the striking component can be intermittently pushed to achieve the striking action. The rotation and striking do not require external power energy, but are achieved through wind power, thereby saving energy. BRIEF DESCRIPTION OF THE DRAWINGS

The electrode rod 33 is fixedly connected to the inner side of the dust suction cylinder 31 and on the lower side of the rotating component 32 through a rectangular plate. The magnetic component 35 is fixedly connected to the outer side of the rotating component 32 and on the inner side of the dust suction cylinder 31, and the striking component 34 is arranged on the outer side of the lower part of the magnetic component 35.

[0043] Electrode sheets are fixedly mounted on the electrode rod 33 , and the density of the electrode sheets gradually decreases from bottom to top. A dust removal cylinder is arranged on the outer side of the electrode rod 33 , and the dust removal cylinder is located on the inner side of the vehicle frame 1 .

[0044] The electrode rods 33 and the electrode sheets can be used to match the corresponding dust amounts, so that discharge can be uniform.

[0045] Furthermore, the negative pressure mechanism 2 includes a negative pressure box 21, a guide tube 22, a filter plate 23, and a fan 24. The negative pressure box 21 is fixedly connected to one side of the frame 1, and the fan 24 is fixedly connected to the inner bottom side of the negative pressure box 21. The upper side of the fan 24 is connected to the guide tube 22, and the inner side of the guide tube 22 is fixedly connected to the filter plate 23. Two groups of guide tubes 22 are provided, and the upper side of the guide tube 22 is connected to the upper part of the dust collection tube 31 through a hose.

[0046] Furthermore, the rotating assembly 32 includes a fixed cover 321, a bearing shell 322, a fixed ring 323, a bearing 324, a connecting shaft 325, and an impeller 326. The upper side of the dust collection cylinder 31 is fixedly connected with the fixed cover 321, the inner side of the upper part of the dust collection cylinder 31 is provided with a bearing shell 322, the fixed cover 321 is fixedly connected to the fixed cover 321 by screws, the inner side of the bearing shell 322 is installed with a bearing 324, the inner side of the bearing 324 is fixedly connected with a connecting shaft 325, the lower side of the connecting shaft 325 is fixedly connected with the impeller 326, and the upper side of the impeller 326 is fixedly connected with the fixed ring 323.

[0047] Furthermore, the magnetic assembly 35 includes a fixed block 351, a connecting block 352, and a magnetic block 353. The upper side of the fixed ring 323 is fixedly connected with a uniformly distributed fixed block 351, the lower side of the fixed block 351 is fixedly connected with a connecting block 352, the outer side of the connecting block 352 is fixedly connected with an annular rotating block, the inner and outer sides of the annular rotating block are provided with annular tracks, the outer annular track is fixedly connected to the inner wall of the dust collection cylinder 31, the inner annular track is fixedly connected to the outer wall of the dust collection cylinder, the annular rotating block rotates between the inner and outer annular tracks, and the lower side of the connecting block 352 is fixedly connected with a magnetic block 353.

[0048] While electrostatic dust removal is being carried out, the airflow circulation drives the rotating component 32 to rotate. While the rotating component 32 is rotating, it is connected by the fixed ring 323, the fixed block 351, and the connecting block 352 to mobilize the magnetic block 353 to rotate in a circle. While the connecting block 352 is rotating, it drives the annular rotating block to rotate in the inner and outer annular orbits, so that a rotating magnetic field is applied to the outside of the dust collector. The rotating magnetic field force drives the electrons to rotate in a circle, thereby achieving uniform distribution of electrons inside the dust collector and further uniform dust removal.

[0049] Furthermore, the striking assembly 34 includes a pushing rod 341, a force plate 342, a striking block 343, a mounting seat 344, a fixed shaft 345, and a torsion spring 346. The outer side of the lower part of the dust collector is fixedly connected with an evenly distributed mounting seat 344, the inner side of the mounting seat 344 is provided with a fixed shaft 345, the outer side of the fixed shaft 345 is fixedly connected with a torsion spring 346 and a force plate 342, the striking block 343 is fixedly connected between the fixed shaft 345 and the inner side wall of the mounting seat 344, and the lower part of the magnetic block 353 is fixedly installed with a pushing rod 341, and the pushing rod 341 corresponds to the force plate 342.

[0050] While the magnetic block 353 is rotating in a circle, the push rod 341 thereon intermittently pushes the force plate 342, and the force plate 342 drives the torsion spring 346 and the fixed shaft 345 to rotate intermittently, thereby compressing the striking block 343. When the push rod 341 is separated from the force plate 342, the spring force of the striking block 343 drives the torsion spring 346 to strike the dust collection cylinder, thereby vibrating the dust adsorbed inside the dust collection cylinder down, and the dust box 41 collects the dust, and the staff regularly pulls out the dust box 41 for cleaning.

[0051] Furthermore, the collecting assembly 4 includes a dust box 41 and a dust gun 42. The dust box 41 is clamped on the inner side of the bottom of the dust cylinder 31, and a T-shaped block is fixedly connected to the outer side of the dust box 41. A sliding groove corresponding to the T-shaped block is opened on the inner side of the dust cylinder 31, and the outer side of the dust box 41 is connected to the dust gun 42.

[0052] The device is pushed to the area to be vacuumed and dusted, and the staff holds the vacuum gun 42 and scans the area to be vacuumed and dusted. At the same time, the fan 24 is started, and the fan 24 generates wind force. The wind direction is from the guide tube 22 to the direction of the fan 24, and then through the guiding effect of the guide tube 22 and the hose, the wind force sucks the air mixed with dust and impurities from the vacuum gun 42, first enters the upper part of the dust box 41, and then moves upward.

[0053] Furthermore, the electrode sheet is a spherical electrode sheet 5 , and the spherical electrode sheet 5 is fixed to the electrode rod 33 by screws.

[0054] Furthermore, the electrode sheet is a cylindrical electrode sheet 6 , and the cylindrical electrode sheet 6 is fixed to the electrode rod 33 by screws.

[0055] Furthermore, the electrode sheet is a mesh electrode sheet 7 , which is fixedly connected to the electrode rod 33 and distributed in a ring array outside the electrode rod 33 .

[0056] A high voltage current is passed through the positive and negative electrodes of the electrode rod 33. Since the electrode rod 33 is electrically connected to the dust collecting electrode and positive electrode of the dust collector, the gas molecules in the airflow are ionized into positive ions and electrons under the action of the high voltage electric field. These ions and electrons move toward the two poles under the action of the electric field force.

[0057] The charged dust is separated from the airflow under the action of the electric field force, and the negatively charged dust particles move toward the dust collector, where they are adsorbed on the inside by the electrostatic force.

[0058] Since the electrode rod 33 is provided with electrode sheets whose density gradually decreases from bottom to top, the electrode sheets may be spherical electrode sheets 5, cylindrical electrode sheets 6 or mesh electrode sheets 7. Since the dust distribution amount gradually decreases from bottom to top, the dust distribution amount corresponds to the density of the electrode sheets, and then uniform discharge can be performed according to the distribution of the dust distribution amount, thereby improving the electrostatic dust removal capacity.

[0059] The specific usage and function of this embodiment.

[0060] When in use, the device is first pushed to the area to be vacuumed and dusted. The staff holds the vacuum gun 42 and scans the area to be vacuumed and dusted. At the same time, the fan 24 is started. The fan 24 generates wind force, and the wind direction is from the guide tube 22 to the direction of the fan 24. Then, through the guiding effect of the guide tube 22 and the hose, the wind force sucks the air mixed with dust and impurities from the vacuum gun 42, first enters the upper part of the dust box 41, and then moves upward.

[0061] At the same time, high voltage current is passed through the positive and negative electrodes of the electrode rod 33. Since the electrode rod 33 is electrically connected to the dust collecting electrode and positive electrode of the dust collector, the gas molecules in the airflow are ionized into positive ions and electrons under the action of the high voltage electric field. These ions and electrons move toward the two poles under the action of the electric field force.

[0062] The charged dust is separated from the airflow under the action of the electric field force, and the negatively charged dust particles move toward the dust collector, where they are adsorbed on the inside by the electrostatic force.

[0063] Since the electrode rod 33 is provided with electrode sheets whose density gradually decreases from bottom to top, the electrode sheets may be spherical electrode sheets 5, cylindrical electrode sheets 6 or mesh electrode sheets 7. Since the dust distribution amount gradually decreases from bottom to top, the dust distribution amount corresponds to the density of the electrode sheets, and then uniform discharge can be performed according to the distribution of the dust distribution amount, thereby improving the electrostatic dust removal capacity.

[0064] While electrostatic dust removal is being carried out, the airflow circulation drives the rotating component 32 to rotate. While the rotating component 32 is rotating, it is connected by the fixed ring 323, the fixed block 351, and the connecting block 352 to mobilize the magnetic block 353 to rotate in a circle. While the connecting block 352 is rotating, it drives the annular rotating block to rotate in the inner and outer annular orbits, so that a rotating magnetic field is applied to the outside of the dust collector. The rotating magnetic field force drives the electrons to rotate in a circle, thereby achieving uniform distribution of electrons inside the dust collector and further uniform dust removal.

[0065] While the magnetic block 353 is rotating in a circle, the push rod 341 thereon intermittently pushes the force plate 342, and the force plate 342 drives the torsion spring 346 and the fixed shaft 345 to rotate intermittently, thereby compressing the striking block 343. When the push rod 341 is separated from the force plate 342, the spring force of the striking block 343 drives the torsion spring 346 to strike the dust collection cylinder, thereby vibrating the dust adsorbed inside the dust collection cylinder down, and the dust box 41 collects the dust, and the staff regularly pulls out the dust box 41 for cleaning.

[0066] Since the filter plate 23 is arranged inside the guide tube 22, the air entering the fan 24 can be dust-removed and filtered again.

[0067] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
