[0025] Figure 3 This is a structural schematic diagram of an air path module provided by an embodiment of the present utility model. Specific embodiments

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] In view of the problems mentioned in the background art, Figure 1 This is a front view structural schematic diagram of an electrostatic dust removal cabinet provided by an embodiment of the present utility model, Figure 2 For Figure 1 a side view structural schematic diagram of the electrostatic dust removal cabinet, see Figure 1 and Figure 2 , the electrostatic dust removal cabinet includes: a cabinet body 110, and the cabinet body 110 includes a dust removal chamber 120 and a dust suction chamber 130 which are isolated from each other;

[0028] A plurality of ion air nozzles 140, and the ion air nozzles 140 are distributed in the dust removal chamber 120; the ion air nozzles 140 are connected to a high-voltage ion gas source 310; the ion air nozzles 140 are used for jetting ion gas;

[0029] An air duct 160, and both ends of the air duct 160 are respectively communicated with the dust removal chamber 120 and the dust suction chamber 130;

[0030] A fresh air module 150, which is arranged in the dust suction chamber 130, the air inlet of the fresh air module 150 is connected to the air duct 160 communicating with the dust suction chamber 130, and the air outlet of the fresh air module 150 is arranged at the bottom of the dust suction chamber 130; the fresh air module 150 is configured to suck the air in the dust removal chamber 120 and filter the air and then discharge it from the cabinet body 110.

[0031] Specifically, the dust removal bin 120 and the dust collection bin 130 in the cabinet 110 can be arranged adjacent to each other, which is conducive to reducing the layout length of the air duct 160 between the dust removal bin 120 and the dust collection bin 130, wherein the dust removal bin 120 and the dust collection bin 130 are spatially separated by a partition. In the working state (the corresponding bin door is closed), the dust removal bin 120 constitutes a sealed space, which is only connected to the dust collection bin 130 by the air duct 160, which can avoid secondary dust contamination of the items to be cleaned. Exemplarily, in an embodiment of the present invention, the dust removal bin 120 and the dust collection bin 130 are stacked up and down, the dust removal bin 120 is close to the top of the cabinet 110, and the dust collection bin 130 is close to the bottom of the cabinet 110. The dust removal bin 120 and the dust collection bin 130 can be equipped with corresponding bin doors, and the opening and closing methods of the bin doors are not limited, for example, they can be open sideways, inwardly open, or outwardly open. Among them, a sealing strip can be provided on the inner side of the door of the dust removal bin 120 to improve the sealing performance of the door of the dust removal bin 120 when it is closed.

[0032] When in use, it is necessary to open the door of the dust removal bin 120, put the items to be cleaned into the dust removal bin 120, and start the dust removal operation after closing the door. In some applications, the door is not closed properly and is ajar, resulting in problems such as air leakage and dust intrusion in the dust removal bin 120 during the dust removal process. Therefore, in some embodiments, a sensor 210 is further provided on the inner wall of the dust removal bin 120, and the sensor 210 can be used to detect the opening and closing status of the door. When the sensor 210 detects that the door is in the open state, the dust removal operation is not allowed to be performed. When the sensor 210 detects that the door is in the closed state, it means that the dust removal operation is ready to be performed, thereby improving the safety of the dust removal operation.

[0033] In order to further improve the static electricity removal and dust removal effects within the dust removal bin 120, the cleaning effect can be improved by arranging the positions of the ion air nozzles 140. For example, in some embodiments, multiple ion air nozzles 140 can be set at the top of the dust removal bin 120. The ion gas ejected by the high-pressure ion gas source 310 is blown into the dust removal bin 120 through the ion air nozzles 140. After being blocked by the bottom and side walls of the dust removal bin 120, the ion gas can form a gas vortex at the position of the workpiece to be cleaned, which is conducive to comprehensively removing static electricity from the workpiece to be cleaned and blowing away dust from the workpiece to be cleaned.

[0034] In other embodiments, multiple ion nozzles 140 can be partially set on the top of the dust removal bin 120 and partially set on the side wall of the dust removal bin 120. The ion gas ejected by the high-pressure ion gas source 310 is blown out to the dust removal bin 120 through the ion nozzle 140. The gas flow direction blown out by the ion nozzle 140 on the top and the ion nozzle 140 on the side wall is perpendicular, further strengthening the gas vortex at the position of the parts to be cleaned and improving the static electricity removal and dust removal effects.

[0035] Continue to see Figure 2, One end of the air duct 160 is connected to the dust removal bin 120, and the other end of the air duct 160 is connected to the dust suction bin 130. Exemplarily, the dust removal bin 120 can be provided with a wind recovery port, and the wind recovery port can be set in a shape similar to a "flare", with the air outlet with a larger opening size facing the internal space of the dust removal bin 120, and the air outlet with a smaller opening size is connected to the air duct 160, so as to improve the gas suction efficiency of the fresh air module 150 for the dust removal bin 120. The other end of the air duct 160 is connected to the air inlet of the fresh air module 150 in the dust suction bin 130, and the fresh air module 150 sucks the gas in the dust removal bin 120, filters it and then discharges it.

[0036] A corresponding filtering unit can be provided at the air inlet of the fresh air module 150. In combination with Figure 2 , Exemplarily, the fresh air module 150 includes a first filtering unit 151 and a second filtering unit 152. The first filtering unit 151 is arranged on the side close to the air inlet of the fresh air module 150, and the second filtering unit 152 is arranged on the side of the first filtering unit 151 away from the air inlet of the fresh air module 150. The first filtering unit 151 is used to filter out the particles in the gas in the dust removal bin 120 sucked in, and the second filtering unit 152 is used to filter the gas in the dust removal bin 120 sucked in again to improve the cleanliness of the gas entering the interior of the fresh air module 150. Exemplarily, the first filtering unit 151 here can adopt a filter screen to filter out larger particles, and the second filtering unit 152 can adopt activated carbon filter cotton to filter out smaller particles. In order to further improve the cleanliness of the gas discharged by the fresh air module 150, a filtering unit 153 can also be provided at the air outlet of the fresh air module 150. The filtering unit 153 can be arranged on the outer side of the air outlet of the fresh air module 150 or on the inner side of the air outlet of the fresh air module 150. Exemplarily, referring to Figure 2 , The filtering unit 153 is arranged on the outer side of the air outlet of the fresh air module 150, which can facilitate later disassembly and replacement maintenance. The filtering unit 153 is provided at the air outlet of the fresh air module 150, which can further filter the air discharged by the fresh air module 150, improve the gas cleanliness and avoid polluting the surrounding environment with the discharged gas. Further, the air outlet of the fresh air module 150 is arranged at the bottom of the dust suction bin 130, and the discharged gas can be far away from the dust removal bin 120, avoiding secondary dust influence on the dust removal device when it is taken out.

[0037] The electrostatic dust removal cabinet provided by the embodiment of the present utility model is provided with a dust removal chamber 120 and a dust suction chamber 130 in the cabinet body 110. By arranging a plurality of ion air nozzles 140 in the dust removal chamber 120, a high-voltage ion gas source 310 provides an air flow with positive and negative charges. This air flow is blown out at high speed by the ion air nozzles 140, which can neutralize the charges on the surface of the workpiece to be cleaned and eliminate static electricity. At the same time, the high-speed gas can also blow off the surface dust, impurities, etc. of the workpiece to be cleaned. The fresh air module 150 sucks the gas in the dust removal chamber 120 through the air duct 160, filters it and discharges it from the bottom of the cabinet body 110, thereby completing the automatic dust removal of the workpiece to be cleaned. The electrostatic dust removal equipment of the embodiment of the present utility model has a simple structure and a small volume, can automatically eliminate static electricity and dust, improves the dust removal effect, improves the cleanliness of the discharged gas during cleaning, and is suitable for dust removal applications in various production scenarios.

[0038] Continue to refer to Figure 1 and Figure 2 , the electrostatic dust removal cabinet further includes a lifting mechanism 220. The output end of the lifting mechanism 220 is connected with a base 122. The lifting mechanism 220 is configured to drive the base 122 to lift in the dust removal chamber. Specifically, the base 122 is independently arranged in the dust removal chamber 120. The lifting mechanism 220 can drive the base 122 to complete lifting. That is to say, the base 122 can move up and down relative to the side wall of the dust removal chamber 120, so as to adjust the position of the base 122 in the cabinet body to adapt to the size of the workpiece to be cleaned. Exemplarily, the lifting mechanism 220 includes a lifting motor 222 and a lifting shaft 221. The lifting shaft 221 is installed on one side of the base 122 away from the accommodation space of the dust removal chamber 120. The lifting shaft 221 is arranged along the lifting direction. One end of the lifting shaft 221 is connected with the rotating shaft of the lifting motor 222, and the other end of the lifting shaft 221 is connected with the base 122. When the lifting motor 222 works, its rotating shaft provides a rotational motion, which is converted into a linear motion in the lifting direction through the lifting shaft 221, thereby driving the base 122 to complete the lifting action.

[0039] In some embodiments, in order to avoid the problem that the friction between the base 122 and the workpiece to be cleaned causes damage to the workpiece to be cleaned when the workpiece to be cleaned enters and exits the dust removal chamber 120, a plurality of parallel rollers 230 are rotatably connected to the base 122. The rotation of each roller 230 can guide the workpiece to be cleaned to enter and exit the dust removal chamber 120. Specifically, both ends of the roller 230 are connected to both sides of the base 122. The rollers 230 are arranged in parallel. The extending direction of the rollers 230 is perpendicular to the direction in which the chamber door points to the dust removal space. That is to say, when placing the workpiece to be cleaned into the dust removal space or taking out the workpiece to be cleaned, the workpiece to be cleaned and the base 122 are in rolling friction, so as to reduce the bottom wear of the workpiece to be cleaned.

[0040] Figure 3 For the structure schematic diagram of an air circuit module provided by the embodiment of the present utility model, in combination withFigure 2 See Figure 3 , the electrostatic dust removal cabinet includes an air circuit module, and the air circuit module includes an air circuit pipeline, a switching valve 320 provided on the air circuit pipeline, and at least one control valve 330;

[0041] The air circuit pipeline is configured to connect the high-voltage ion gas source 310 with each ion air nozzle 140;

[0042] The switching valve 320 is configured to connect / close the high-voltage ion gas source 310;

[0043] At least one control valve 330 is configured to control whether each ion air nozzle 140 sprays ion gas.

[0044] Specifically, one end of the switching valve 320 of the air circuit pipeline is connected to the high-voltage ion gas source 310; the other end of the switching valve 320 is connected to at least one control valve 330; at least one control valve 330 is connected to multiple ion air nozzles 140. The switching valve 320 and the control valve 330 can control the on or off state of the air circuit pipeline. In some embodiments, the corresponding opening degrees can also be controlled by the switching valve 320 and the control valve 330. Therefore, the switching valve 320 can control the flow rate of the gas output by the high-voltage ion gas source 310, and then, according to the connection relationship between the control valve 330 and the ion air nozzle 140, control the spraying flow rate of a specific ion air nozzle 140. For example, when there are multiple ion air nozzles 140, one control valve 330 can be connected to several of the ion air nozzles 140, and one control valve 330 can also be connected to one ion air nozzle 140. That is to say, the control valve 330 can control the spraying flow rate of the designated ion air nozzle 140, or spraying in a designated area and not spraying in a designated area, so as to achieve diversified dust removal methods and improve the dust removal effect.

[0045] In some embodiments, the electrostatic dust removal cabinet further includes an ion air gun 340. The ion air gun 340 is connected to a branch pipeline, and the branch pipeline is communicated with the air pipeline. Specifically, the ion air gun 340 is connected to the air pipeline through the branch pipeline. Exemplarily, a branch pipeline connected to the ion air gun 340 can be provided between the switch valve 320 and at least one control valve 330. The ion air gun 340 can be held by an operator, and the ion air gun 340 can be used to further remove dust before or after cleaning, improving the dust removal effect and enriching the dust removal modes of the electrostatic dust removal cabinet. When applying the electrostatic dust removal cabinet, the operator can select the ion air gun 340 and cooperate with the on / off states of the switch valve 320 and the control valve 330 to achieve various dust removal methods. For example, when both the switch valve 320 and the control valve 330 are kept open, the dust removal operation can be automatically performed in the dust removal chamber 120. At the same time, the ion air gun 340 can be used to manually remove dust from other parts to be cleaned before cleaning. When the switch valve 320 is open and the control valve 330 is closed, the ion air gun 340 can be used to manually remove dust from other parts to be cleaned before cleaning.

[0046] Continue to refer to Figure 1 and Figure 2 , the ion air gun 140 can be accommodated in the cabinet body 110. Exemplarily, an intermediate chamber can be provided in the cabinet body 110. For example, the intermediate chamber is provided between the dust removal chamber 120 and the dust suction chamber 130. The intermediate chamber can be obtained by spatially isolating with a partition board. The intermediate chamber can accommodate the ion air gun 340 and can also provide an installation space for the setting of the lifting mechanism 220, making the overall structure of the electrostatic dust removal cabinet more regular and facilitating maintenance and installation.

[0047] Continue to refer to Figure 1 and Figure 2 , the electrostatic dust removal cabinet can further include a control unit. The control unit is electrically connected to the fresh air module 150, the lifting mechanism 220 and the air pipeline module. Specifically, a control chamber can also be obtained by isolating with a partition board in the cabinet body 110. The control chamber can be used to accommodate the control unit.

[0048] The control chamber can be provided at the top of the cabinet body 110, and the control unit is arranged in the control chamber, which is convenient for operation and obtaining the working parameters of the electrostatic dust removal cabinet. The control unit has data processing capabilities such as storage, logical transportation, and control signal output, and can coordinate and manage the working process of the electrostatic dust removal cabinet. The control unit can be provided with corresponding function keys for conveniently controlling the corresponding functions of the electrostatic dust removal cabinet. For example, the control unit can be connected to the lifting mechanism 220, and the control unit can send a control signal to control the lifting or lowering action of the lifting mechanism 220, so that the corresponding keys can be used for quick adjustment.

[0049] The control unit can also be connected to the air circuit module. The control unit controls the on / off states of the switching valve 320 and the control valve 330 to implement multiple dust removal methods. For example, when both the switching valve 320 and the control valve 330 are kept open, the dust removal operation can be automatically performed in the dust removal bin 120. At the same time, the pre-cleaning dust removal of other parts to be cleaned can also be manually performed by the ion air gun 340. When the switching valve 320 is open and the control valve 330 is closed, the ion air gun 340 can be used to manually perform pre-cleaning dust removal on other parts to be cleaned.

[0050] The control unit can also be connected to the fresh air module 150. The fresh air module 150 is a ventilation device that can extract the gas in the dust removal bin 120 and filter the gas through the built-in filtering unit. The fresh air module 150 can adopt existing fresh air fan equipment. Usually, multiple dust removal modes are configured in the fresh air fan equipment, such as heating, purification, fresh air, and negative ion modes. Relevant sensors are also configured, which can be used to detect parameters such as air quality and filter life, and provide functions for customizing the adjustment of parameters such as timing parameters and exhaust parameters. Based on the control function of the fresh air fan equipment, a connection can be established between the control unit and the corresponding controller of the fresh air fan equipment, and the control unit can be used to obtain and adjust the working parameters of the fresh air fan equipment. For the convenience of the operator's control operation, the control unit can be configured with a touch display screen to display the working parameters of the fresh air fan equipment through the touch display screen, and send corresponding working parameter instructions through the touch display screen to control the functions of the fresh air fan equipment. The working parameters here include but are not limited to dust removal mode, air quality, timing parameters, and exhaust settings, etc. It should be noted that the air quality can include the air quality of the dust removal box, the air quality after cleaning, and the Air Quality Index (AQI). Exemplarily, the AQI parameter can reflect the current air dust removal effect. For example, when the AQI index is lower than 001, it indicates that the cleaning effect is good. When the AQI index exceeds 50, it indicates that the cleaning effect is average, and then continuous cleaning or shutdown for inspection / cleaning of the filter is required.

[0051] In the above embodiments, the electrostatic dust removal cabinet may further include a circuit module for supplying power to the electrostatic dust removal cabinet. The circuit module may include a 220V leakage protection device socket and a set of AC contact control devices. The AC contact control device generally refers to an AC contactor, which is an electrical control component that uses electromagnetic force to control the on / off of a circuit. The AC contact control device has a high response speed and action sensitivity, and can withstand large currents and voltages, meeting the control requirements of electrical equipment. An AC contact control device is provided between the electrostatic dust removal cabinet and the external power supply to control the on / off of the external power supply through the AC contact control device, so that the electrostatic dust removal cabinet can be quickly switched to the powered-on state or the powered-off state. The leakage protection socket, as the internal power supply access point of the electrostatic dust removal cabinet, can supply working power to the control unit, the fresh air module 150, the lifting mechanism 220, and the corresponding sensors 210, etc., and the leakage protection socket plays a role in leakage protection.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
