Description

Technical Field

[0001] The present invention relates to the technical field of anti-static ion blowers, specifically to the field of performance index detection of ion blowers. More specifically, it relates to a monitoring device for an ion blower and an ion blower. Background Art

[0002] An ion blower is an anti-static electronic product, generally composed of a high-voltage package, a blower, and an emission needle holder. Ion blowers are divided into two types: DC and AC. The so-called DC ion blower is that the high-voltage package generates two high-voltage output terminals, positive and negative, which respectively output two stable DC high voltages to the air medium through the emission needles; the so-called AC ion blower is that a transformer outputs an AC high voltage to the air medium through the emission needles. After the above positive and negative DC high voltages or AC high voltages ionize the air, positive and negative ions are generated, and then through the action of the blower, the positive and negative ions are sent into the air to neutralize the positive and negative static charges carried on objects and products, so as to achieve the purpose of eliminating static electricity.

[0003] Generally, there are two indicators for evaluating the quality of an ion blower. The first is the balance voltage (also known as the residual voltage): that is, after the positive and negative ions generated by the ion blower neutralize the static electricity in the environment, the static voltage converted from the remaining static charges. The second is the positive and negative ion dissipation time (the time to neutralize static electricity): that is, the time taken for the positive and negative ions generated by the ion blower to neutralize the positive and negative static charges in the environment, which reflects its static electricity control ability.

[0004] Currently, the main method for detecting the two indicators of the balance voltage and the positive and negative ion dissipation time of an ion blower in the working state (especially in an electronic industrial production workshop) is: a special person regularly places a professional device (flat detector) on the workbench for monitoring. Its disadvantages are time-consuming and laborious, and it cannot monitor the performance indicators of the ion blower in real time, and it cannot confirm whether the ion blower can always provide completely effective static electricity protection. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a monitoring device for an ion blower, which can detect the positive and negative ions at the air outlet of the ion blower in real time, so as to provide data support for us to analyze and obtain the two indicators of the real-time balance voltage and the positive and negative ion dissipation time of the ion blower in the working state.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A monitoring device for an ion blower is provided. The ion blower includes a housing having an air outlet. The monitoring device includes a hollow insulating bracket, a first acquisition component, and a second acquisition component. Both the first acquisition component and the second acquisition component include n metal mesh sheets connected in series by wires, where n is an integer greater than or equal to 2. The n metal mesh sheets included in the first acquisition component and the n metal mesh sheets of the second acquisition component are alternately and equidistantly fixed around the center of the insulating bracket to the insulating bracket; the monitoring device further includes a power supply module respectively connected to the first acquisition component and the second acquisition component, a first measurement module connected to the first acquisition component and the power supply module, and a second measurement module connected to the second acquisition component and the power supply module; the insulating bracket is used to be installed on the housing and face the air outlet so that positive and negative ions generated when the ion blower works will pass through the metal mesh sheets. The power supply module is a power supply module for respectively applying a bias positive voltage and a bias negative voltage to the first acquisition component and the second acquisition component. The first measurement module is used to measure the current flowing through the first acquisition component when the ion blower works, and the second measurement module is used to measure the current flowing through the second acquisition component when the ion blower works.

[0007] When using the monitoring device with the above technical solution, the insulating bracket is installed on the housing and faces the air outlet so that positive and negative ions generated when the ion blower works will pass through the metal mesh sheets. The power supply module respectively applies a bias positive voltage and a bias negative voltage to the first acquisition component and the second acquisition component. The first measurement module measures the current flowing through the first acquisition component when the ion blower works, and the second measurement module measures the current flowing through the second acquisition component when the ion blower works. Thus, real-time detection of positive and negative ions at the air outlet of the ion blower is achieved, and further data support is provided for us to analyze and obtain two indicators of the real-time balance voltage and the positive and negative ion dissipation time of the ion blower in the working state.

[0008] In the monitoring device for an ion blower provided by the present invention, the metal mesh sheet includes a main body portion with a fan-shaped contour. The insulating bracket has a central circular hole and 2n fan-shaped first through holes. The 2n first through holes are equidistantly arranged around the central circular hole, and the 2n metal mesh sheets are respectively aligned with the 2n first through holes. In this way, it is ensured that the insulating bracket does not block the air outlet of the ion blower, and positive and negative ions generated by the ion blower will pass through the metal mesh sheets after flowing out from the air outlet.

[0009] In the monitoring device for an ion blower provided by the present invention, the insulating bracket has 2n second through-holes arranged at equal intervals around the central circular hole and 2n third through-holes arranged at equal intervals around the central circular hole. The 2n second through-holes respectively correspond to the tops of the 2n first through-holes, and the 2n third through-holes respectively correspond to the 2n second through-holes; the top of the main body of the metal mesh has a first mounting hole, and the metal mesh further includes a mounting portion having a second mounting hole. The mounting portion is connected to the side of the main body away from the top. The first mounting hole and the second mounting hole of one metal mesh respectively align with the corresponding second through-hole and the third through-hole. In this way, the metal mesh can be stably fixed on the insulating bracket.

[0024] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0025] As Figures 1 to 4 shown, the first embodiment of the monitoring device for the ion blower 200 provided by the present invention.

[0026] The structure of the ion blower 200 is basically the same as the existing one, and it includes a housing 201 and a high-voltage package, a blower, and an emission needle holder provided in the housing 201. The middle of the housing 201 has an air outlet.

[0027] The ion blower 200 includes a housing 201, and the housing 201 has an air outlet. The monitoring device includes a hollow insulating bracket 1, a first acquisition component, and a second acquisition component. Both the first acquisition component and the second acquisition component include n metal mesh sheets 2 connected in series by wires, where n is an integer greater than or equal to 2. The n metal mesh sheets 2 included in the first acquisition component and the n metal mesh sheets 2 of the second acquisition component are alternately and equidistantly fixed around the center of the insulating bracket 1 to the insulating bracket 1; the monitoring device further includes a power supply module respectively connected to the first acquisition component and the second acquisition component, a first measurement module 3 connected to the first acquisition component and the power supply module, and a second measurement module 4 connected to the second acquisition component and the power supply module. When using the monitoring device with the above technical solution, the insulating bracket 1 is installed on the housing 201 and faces the air outlet so that the positive and negative ions generated when the ion blower 200 works will pass through the metal mesh sheets 2 (see Figure 3) The power supply module applies a bias positive voltage and a bias negative voltage to the first acquisition component and the second acquisition component respectively. The first measurement module 3 measures the current flowing through the first acquisition component when the ion blower 200 is operating, and the second measurement module 4 measures the current flowing through the second acquisition component when the ion blower 200 is operating. Thus, real-time detection of positive and negative ions at the air outlet of the ion blower 200 is achieved, and further, data support is provided for us to analyze and obtain two indicators, namely, the real-time balance voltage and the positive and negative ion dissipation time of the ion blower 200 in the working state.

[0028] In this embodiment, n is 4. In other embodiments, n can be other integers greater than 2, such as 2, 3, 5, etc.

[0029] In this embodiment, refer to Figure 2 , the four metal mesh sheets 2 included in the first acquisition component and the four metal mesh sheets 2 of the second acquisition component are alternately and equidistantly fixed around the center of the insulating bracket 1 to the insulating bracket 1. That is to say, a metal mesh sheet 2 belonging to the second acquisition component is arranged between every two metal mesh sheets 2 belonging to the first acquisition component. Conversely, it can also be considered that a metal mesh sheet 2 belonging to the first acquisition component is arranged between every two metal mesh sheets 2 belonging to the second acquisition component. In short, the metal mesh sheets 2 belonging to the same first acquisition component are not adjacent, and the metal mesh sheets 2 belonging to the same second acquisition component are not adjacent either.

[0030] In this embodiment, the metal mesh sheet 2 includes a main body portion 21 with a fan-shaped contour, and the main body portion 21 is provided with a plurality of ventilation openings 212. Refer to Figure 1, the insulating bracket 1 has a central circular hole 11 and eight fan-shaped first through holes 12. The eight first through holes 12 are equally spaced around the central circular hole 11, and the eight metal mesh sheets 2 are respectively aligned with the eight first through holes 12. In this way, it is ensured that the insulating bracket 1 does not block the air outlet of the ion blower 200, and the positive and negative ions generated by the ion blower 200 will pass through the metal mesh sheet 2 after flowing out of the air outlet. The insulating bracket 1 also has eight second through holes 13 equally spaced around the central circular hole 11 and eight third through holes 14 equally spaced around the central circular hole 11. The second through holes 13 are located between the central circular hole 11 and the first through holes 12, and the third through holes 14 are located on the side of the first through holes 12 away from the central circular hole 11. The eight second through holes 13 respectively correspond to the tops of the eight first through holes 12, and the eight third through holes 14 respectively correspond to the eight second through holes 13; the top of the main body 21 of the metal mesh sheet 2 has a first mounting hole 211, and the metal mesh sheet 2 further includes a mounting portion 22 having a second mounting hole 221. The mounting portion 22 is connected to the side of the main body 21 away from the top. The first mounting hole 211 and the second mounting hole 221 of one metal mesh sheet 2 respectively align with the corresponding second through hole 13 and the third through hole 14. In this way, the metal mesh sheet 2 can be stably fixed on the insulating bracket 1 by screws.

[0031] In this embodiment, the power supply module includes a first battery pack 5 with the positive electrode grounded and the negative electrode connected to the first acquisition component, and a second battery pack 6 with the negative electrode grounded and the positive electrode connected to the second acquisition component. Among them, the first battery pack 5 and the first acquisition component form a first loop, and the second battery pack 6 and the second acquisition component form a second loop. In this way, referring to Figure 4 , the power supply module applies a bias positive voltage to the first acquisition component through the first battery pack 5, and applies a bias negative voltage to the second acquisition component through the second battery pack 6, forming a space electric field in space. When positive and negative ions pass through the first acquisition component and the second acquisition component, some ions will change their movement directions under the action of the space electric field, and thus hit the metal mesh sheet 2, causing a current to be formed in the first loop and the second loop.

[0032] In this embodiment, the first measurement module 3 includes a first resistor connected between the first battery pack 5 and the first acquisition component, and a first voltmeter connected in parallel with the first resistor; the second measurement module 4 includes a second resistor connected between the second battery pack 6 and the second acquisition component, and a second voltmeter connected in parallel with the second resistor. In this way, the voltage across the first resistor can be measured by the first voltmeter, and then the current in the first return flow (i.e., the current flowing through the first acquisition component) can be obtained. The voltage across the second resistor can be measured by the second voltmeter, and then the current in the second loop (i.e., the current flowing through the second acquisition component) can be obtained. Thus, real-time detection of positive and negative ions at the air outlet of the ion blower 200 is achieved.

[0033] Further, referring to Figure 5 , the monitoring device further includes a humidity sensor 71 for measuring the humidity of the environment where the ion blower 200 is located, a temperature sensor 72 for measuring the temperature of the environment where the ion blower 200 is located, a wind speed sensor 73 for measuring the wind speed at the air outlet of the ion blower 200, and a processor 74 respectively connected to the humidity sensor 71, the temperature sensor 72, the wind speed sensor 73, the first measurement module 3 and the second measurement module 4. In this way, the processor 74 can perform real-time fitting based on the temperature signal detected by the temperature sensor 72, the humidity signal detected by the humidity sensor 71, the wind speed signal detected by the wind speed sensor 73, and the current signals detected by the first measurement module 3 and the second measurement module 4 to obtain the real-time balance voltage and the positive and negative ion dissipation times of the ion blower 200.

[0034] Further, the monitoring device further includes a display 75 connected to the processor. In this way, it is convenient for the operator to observe the real-time balance voltage and the positive and negative ion dissipation times of the ion blower 200 in a timely manner. In this embodiment, the display can be an LCD screen.

[0035] Further, the monitoring device further includes an alarm 76 connected to the processor. In this way, when it is detected that the balance voltage or the positive and negative ion dissipation time index of the ion blower 200 exceeds the standard, an alarm signal can be sent through the alarm, so that the operator can handle it in a timely manner. In this embodiment, the alarm can emit a sound signal or a light signal. When a sound signal needs to be emitted, the alarm can select a speaker, and the processor controls the speaker to emit a beeping alarm sound to remind the operator. When a light signal needs to be emitted, the alarm can select an led light, and the processor controls the led light to flash to remind the operator.

[0036] Implementing the monitoring device provided by the present invention for the ion blower 200 can achieve the following beneficial effects:

[0037] 1. Install the insulating bracket 1 on the housing 201 and face the air outlet, so that the positive and negative ions generated when the ion blower 200 operates will pass through the metal mesh 2. The power supply module applies a bias positive voltage and a bias negative voltage to the first acquisition component and the second acquisition component respectively. The first measurement module 3 measures the current flowing through the first acquisition component when the ion blower 200 operates, and the second measurement module 4 measures the current flowing through the second acquisition component when the ion blower 200 operates. Thus, real-time detection of the positive and negative ions at the air outlet of the ion blower 200 is realized, and further data support is provided for us to analyze and obtain the two indicators of the real-time balance voltage and the positive and negative ion dissipation time of the ion blower 200 under the working state.

The processor can perform real-time fitting according to the temperature signal detected by the temperature sensor, the humidity signal detected by the humidity sensor, the wind speed signal detected by the wind speed sensor, and the current signals detected by the first measurement module 3 and the second measurement module, to obtain the real-time balance voltage and the positive and negative ion dissipation time of the ion blower 200.
