Description

Technical Field

[0001] The present application relates to the technical field of ion blowers, and in particular to a direct current ion blower. Background Art

[0002] Removing static electricity is very important for industrial manufacturing. For production lines of electrostatically sensitive components, such as electronic product assembly, microelectronics manufacturing, printing, packaging and precision manufacturing, the harm of static electricity cannot be underestimated. Static electricity is generally removed by using static electricity removal equipment such as ion blowers. Ion blowers are equipped with ion emitters connected to high voltage. The ion emitters generate tip discharges to ionize the air, generate a large amount of airflow with positive and negative charges, and neutralize the charges on the object. When the surface of an object is negatively charged, it absorbs the positive charge in the airflow; when the surface of an object is positively charged, it absorbs the negative charge in the airflow, thereby neutralizing the static electricity on the surface of the object and achieving the purpose of removing static electricity.

[0003] For DC ion blowers (whether pulsed DC or steady-state DC), a voltage of fixed polarity is applied to a fixed ion emission needle, which causes charged small particles in the air to accumulate on the ion emission needle. The accumulation of these small particles will affect the electric field distribution of the corona phenomenon, thereby affecting the efficiency of ion generation and causing an imbalance between positive and negative ions. At the same time, the accumulation of small particles will also make it easy for solid particles (dust) in the air to accumulate on the ion emission needle, aggravating the electric field distribution that affects the corona phenomenon and further affecting the efficiency of ion generation. Therefore, the ion emission needle must be frequently dusted.

[0004] With regard to the above-mentioned related technologies, the existing ion emission needle dust removal is mainly carried out manually, which is to rotate the brush installed in the needle holder box (ion generator) by hand crank, and the brush and the surface of the ion emission needle are swept to remove the dust on the surface. The manual operation is more troublesome and the labor intensity is high, so it needs to be improved. Utility Model Content

[0005] In order to facilitate dust removal on the ion emission needle, the present application provides a DC ion blower.

[0006] The DC ion blower provided in this application adopts the following technical solution:

[0007] A DC ion blower comprises a housing, a fan, an annular frame, an ion emission needle and an electrode cleaning assembly, wherein the fan is arranged in the housing, the annular frame is arranged in the housing and is located on the side where the blowing end of the fan is located; the ion emission needle is connected to the annular frame and is distributed with a plurality of ion emission needles at intervals along the circumferential direction; the electrode cleaning assembly is arranged on the annular frame and is used to clean each of the ion emission needles;

[0008] The electrode cleaning assembly includes a cleaning motor and a cleaning brush. The cleaning brush is connected to the cleaning motor. The cleaning motor is used to control the rotation of the cleaning brush, and the cleaning brush is used to clean the ion emission needle.

[0009] By adopting the above technical solution, the basic principle of the DC ion blower is to use a DC high-voltage generator to increase the voltage, output positive voltage and negative voltage respectively, generate a strong electric field between the positive and negative discharge electrodes, and ionize air molecules. The ion emission needle discharges to generate positive and negative ions, the fan operates and blows out air, and the positive and negative ions are blown to the surface of the object to be treated through the ion wind.

[0010] When the surface of the object is at a positive potential, negative ions will neutralize it; conversely, if the surface is at a negative potential, positive ions will neutralize it. This design enables the DC ion blower to generate positive and negative ions without grounding, and there are sufficient positive and negative ions acting on the surface of the object, so the static electricity neutralization speed is very fast.

[0011] During the startup process of the DC ion blower, the cleaning motor will drive the cleaning brush to clean the ion emission needle to remove surface dust and ensure normal operation.

[0012] Preferably, the cleaning brush is detachably connected to the cleaning motor.

[0013] By adopting the above technical solution, when the cleaning brush is damaged or needs to be cleaned, it is convenient for the user to disassemble and replace the cleaning brush.

[0014] Preferably, it further includes a fixing column. A limiting groove is provided on the output shaft of the cleaning motor. The cleaning brush is snap-fitted in the limiting groove, and the fixing column passes through the cleaning brush and is screwed to the output shaft of the cleaning motor.

[0015] By adopting the above technical solution, during installation, first snap the cleaning brush onto the limiting groove of the output shaft, then pass the fixing column through the cleaning brush, and finally screw it onto the output shaft to complete the fixation of the cleaning brush by relying on the screwing force.

[0016] Preferably, a separation net is detachably connected to the housing. The electrode cleaning assembly is located between the fan and the separation net; a clamping plate is integrally connected to the separation net, and the clamping plate is snap-fitted to the housing.

[0017] By adopting the above technical solution, the separation net can play a role of blocking and protecting the electrode cleaning assembly, preventing the user from accidentally putting their hand into the annular frame and touching the cleaning brush. At the same time, since the separation net can be detached from the housing, the influence on the disassembly and replacement of the cleaning brush is reduced.

[0018] Preferably, a metal mesh cover is detachably connected to the housing. The metal mesh cover is located at the negative pressure end of the fan. The fan is located between the metal mesh cover and the isolation net. The metal mesh cover is locked to the housing by fastening bolts or fastening screws.

[0019] By adopting the above technical solution, the metal mesh cover can shield and protect the other side of the fan, preventing a person's hand from touching the fan and causing danger. At the same time, both the fastening bolts and the fastening screws are detachable components, which can facilitate the removal of the metal mesh cover from the housing.

[0020] Preferably, a power interface, a start-stop switch, and an adjustment knob are provided on the housing. The power interface is used for plugging in an external power cord. The start-stop switch is used to control the operation of the fan. The adjustment knob is used to adjust the ion balance of the ion emission needle.

[0021] By adopting the above technical solution, one end of the external power cord is plugged into the power interface, and the other end is plugged into an external socket to achieve power supply. The start-stop switch can facilitate the staff to quickly control the operation of the fan. In addition, the staff can also adjust the balance of the ion emission needle and control the relative quantity of positive and negative ions by rotating the adjustment knob according to actual needs.

[0022] Preferably, it further includes a support frame and an angle locking bolt. The housing is rotatably connected to the support frame. The angle locking bolt is provided at the hinge joint of the housing and the support frame and is used to lock the housing.

[0023] By adopting the above technical solution, the support frame serves as a carrier for the installation of the housing. At the same time, the staff can adjust the angular orientation of the entire housing according to actual needs, thereby changing the blowing direction of the fan. After adjustment, the angle locking bolt is used to lock it to limit the rotation of the housing and improve practicability.

[0024] Preferably, the support frame is U-shaped, and counterweights are symmetrically distributed at both ends of the support frame.

[0025] By adopting the above technical solution, the counterweights can increase the weight of the entire support frame, so as to lower the center of gravity of the entire DC ion blower, making it not easy for the support frame to tip over when the housing is rotated, and improving stability.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] (1) By setting up the electrode cleaning assembly, during the startup process of the DC ion blower, the cleaning motor drives the cleaning brush to clean the ion emission needle to remove surface dust, ensuring normal operation and reducing the labor intensity of personnel.

[0028] (2) By setting up the isolation net and the metal mesh cover, the isolation net and the metal mesh cover can block the fan and the electrode cleaning assembly, reducing the possibility of accidental contact by the staff.

[0029] (3) By setting up the support frame and the angle locking bolt, the staff can adjust the angle orientation of the entire housing according to actual needs and lock it with the angle locking bolt after adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will describe in detail some embodiments of this application with reference to the drawings. Without conflict, those skilled in the art can combine and combine different embodiments or examples represented in this application and the features of different embodiments or examples.

[0040] The embodiments of this application disclose a DC ion blower. Refer to Figure 1 and Figure 2 , the DC ion blower includes a housing 1, a fan 2, an annular frame 3, ion emission needles 4 and an electrode cleaning assembly 5. The fan 2 and the annular frame 3 are both installed inside the housing 1, and the annular frame 3 is located on the side where the blowing end of the fan 2 is located. The ion emission needles 4 are fixedly connected to the annular frame 3, and a plurality of them are distributed at intervals along the circumference of the annular frame 3, and the ion emission needles 4 are concentrically arranged. The electrode cleaning assembly 5 is installed on the annular frame 3 and is used to clean each ion emission needle 4.

[0041] The basic principle of the DC ion blower is to use a DC high-voltage generator to increase the voltage, output positive voltage and negative voltage respectively, generate a strong electric field between the positive and negative discharge electrodes, and ionize air molecules. The ion emission needles 4 discharge to generate positive and negative ions, the fan 2 rotates and blows out air, and the positive and negative ions are blown to the surface of the object to be acted on through the ion wind.

[0042] When the surface of the object is at a positive potential, the negative ions will neutralize it; conversely, if the surface is at a negative potential, the positive ions will neutralize it. This design enables the DC ion blower to generate positive and negative ions without grounding, and there are sufficient positive and negative ions acting on the surface of the object, and the static electricity neutralization speed is very fast.

[0043] Specifically, the electrode cleaning assembly 5 includes a cleaning motor 51 and a cleaning brush 52. The cleaning motor 51 is fixed on the annular frame 3. The cleaning brush 52 is connected to the cleaning motor 51. The cleaning motor 51 is used to control the rotation of the cleaning brush 52, and the cleaning brush 52 is used to clean the dust adhering to the ion emission needle 4. During the startup process of the DC ion blower, the cleaning motor 51 will drive the cleaning brush 52 to clean the ion emission needle 4 to remove the surface dust and ensure normal operation.

[0044] In this embodiment, the cleaning brush 52 is detachably connected to the cleaning motor 51. A limit groove is provided on the output shaft of the cleaning motor 51. The cleaning brush 52 is clamped in the limit groove, and the cleaning brush 52 is locked on the output shaft of the cleaning motor 51 through a fixing column 6. The fixing column 6 passes through the cleaning brush 52 and is screwed on the output shaft. When the cleaning brush 52 is damaged or needs to be cleaned, it is convenient for the user to disassemble and replace the cleaning brush 52.

[0045] Among them, combined with Figure 3 and Figure 4 , an isolation net 7 and a metal mesh cover 8 are also installed on the housing 1. The isolation net 7 is detachably connected to the housing 1 and is used to block the electrode cleaning assembly 5, so that the electrode cleaning assembly 5 is located between the fan 2 and the isolation net 7. A clamping plate 9 is integrally connected to the isolation net 7. The clamping plate 9 is clamped on the housing 1, and the connection between the isolation net 7 and the housing 1 is realized by relying on the clamping force. The isolation net 7 can play a role in blocking and protecting the electrode cleaning assembly 5, preventing the user from accidentally putting their hand into the annular frame 3 and touching the cleaning brush 52, thus improving safety. At the same time, since the isolation net 7 can be detached from the housing 1, the interference with the disassembly and replacement of the cleaning brush 52 is reduced.

[0046] The metal mesh cover 8 is installed at the negative pressure end of the fan 2. The fan 2 is located between the metal mesh cover 8 and the isolation net 7. The metal mesh cover 8 can provide blocking protection for the other side of the fan 2 to prevent a person's hand from touching the fan 2 and causing danger. In this embodiment, the metal mesh cover 8 is locked to the housing 1 by fastening bolts or fastening screws. Both the fastening bolts and the fastening screws are detachable objects, which can facilitate the staff to disassemble the metal mesh cover 8 from the housing 1.

[0047] In addition, a power interface 10, a start-stop switch 11 and an adjustment knob 12 are also provided on the housing 1. The power interface 10 is used for plugging in an external power cord. One end of the external power cord is plugged into the power interface 10, and the other end is plugged into an external socket to achieve power supply. The start-stop switch 11 is used to control the operation of the fan 2, facilitating the staff to quickly control the working state of the fan 2. The adjustment knob 12 is used to adjust the ion balance of the ion emission needle 4. The staff can also rotate the adjustment knob 12 according to actual needs to control the relative quantity of positive and negative ions.

[0048] In some embodiments, with reference to Figure 1 , the DC ion blower further includes a support frame 13, and the housing 1 is rotatably connected to the support frame 13. An angle locking bolt 14 is also installed at the hinge joint between the housing 1 and the support frame 13, and the angle locking bolt 14 is used to lock the housing 1 to the support frame 13. The staff can adjust the angle orientation of the entire housing 1 according to actual needs, so as to change the blowing direction of the fan 2; after adjustment, the angle locking bolt 14 is used to lock it to limit the rotation of the housing 1 and improve the practicability. As shown in the figure, the support frame 13 is U-shaped, and counterweights 15 are fixedly connected to both ends of the support frame 13. The two counterweights 15 are symmetrically distributed and are both close to the bottom of the support frame 13. The counterweights 15 can increase the weight of the entire support frame 13, so as to lower the center of gravity of the entire DC ion blower, so that when the housing 1 rotates, the support frame 13 is not easily toppled, improving stability.

[0049] The implementation principle of a DC ion blower according to an embodiment of the present application is as follows: During the startup process of the DC ion blower, the cleaning motor 51 will drive the cleaning brush 52 to clean the ion emission needles 4 to remove surface dust, ensure normal operation, and reduce the labor intensity of personnel.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
