Description

Technical Field

[0001] This invention relates to the field of electrostatic jet technology, and more specifically to a multi-channel electrostatic jet device and method. Background Technology

[0002] Medical aesthetic skincare generally uses skincare products or instruments to maintain or stimulate skin contraction to promote regeneration, depending on the skin type. However, the determination of skin type, the selection of skincare products or instruments, and the method of use depend entirely on the operator's own experience, and often fail to achieve good skincare results.

[0003] Traditional treatment for skin trauma typically involves medical staff applying specific medications to the wound based on its condition, followed by bandaging with gauze or other materials. This method is extremely painful for patients with large wounds such as burns, especially the discomfort caused by changing the gauze. Furthermore, for many everyday wounds, improper treatment can lead to further infection.

[0004] Based on the difference in product morphology, electrostatic jetting technology is divided into two types: electrospraying (or electrospraying for short) and electrospinning (or electrospinning for short). Electrospraying produces ultra-fine and uniformly distributed droplets with excellent deposition characteristics, high coverage, and strong penetration. This not only improves the adhesion rate to the back of the target but also helps enhance the activity of the drug in practical applications, showing great promise in numerous industries. Electrospinning, as a special case of electrostatic jetting technology, leverages its fundamental advantages to easily produce nanoscale fibers. This technology boasts advantages such as low spinning cost, abundant raw material sources, and the ability to mass-produce fibers. The high specific surface area, large length / diameter ratio, controllable porosity, and antibacterial properties of spun products have significant application potential in fields such as medical aesthetics, wound dressings, and drug sustained release. The devices for electrospinning and electroblotting are the same; the difference lies in the jet solution and parameters. Polymer solutions with low surface tension and easy filamentation are suitable for electrospinning, while polymer solutions with high surface tension are suitable for electroblotting. When using a lower concentration polymer solution, it is electroblotting, and when using a higher concentration polymer solution, it becomes electrospinning.

[0005] Traditional electrostatic jet devices consist of three main parts: a high-voltage power supply, a nozzle, and a collection device. However, these devices are too bulky, inconvenient to carry and use, and are made of limited materials. Important parameters such as spray distance, skin condition, or wound condition can only be determined based on the user's experience, limiting their application scenarios. Therefore, existing electrostatic jet devices have relatively limited functionality and cannot be flexibly applied according to actual scenarios and individual cases. Summary of the Invention

[0006] Given that traditional skin aesthetics and wound treatment methods are mostly based on visual inspection by professionals or judgment by specific testing instruments, and skin care or treatment plans are given based on experience; moreover, the electrospinning devices used for medical aesthetics and wound dressings are limited in materials and functions and cannot meet the needs of skin care and wound repair for multiple material scenarios, this invention proposes a multi-channel electrostatic jet method and device.

[0007] According to a first aspect of this application, this application provides a multi-channel electrostatic jet device, comprising:

[0008] The housing has a grip portion, which has a conductive portion; the housing also has an internal mounting cavity.

[0009] Multiple liquid storage mechanisms are disposed in the mounting cavity. The liquid storage mechanisms are used to store liquid medicine. The types of liquid medicine stored in each liquid storage mechanism may be the same or different.

[0010] A spraying mechanism is disposed in the mounting cavity and includes a nozzle and a conductive connector. The housing is also provided with a mounting hole communicating with the mounting cavity. The nozzle is mounted in the mounting hole, and one end of the conductive connector is communicating with the nozzle.

[0011] Multiple liquid supply mechanisms are disposed in the mounting cavity. Each liquid supply mechanism corresponds to a liquid storage mechanism. The other end of the conductive connector and the liquid storage mechanism are connected to the liquid supply mechanism. One of the liquid supply mechanisms is used to supply the liquid stored in the corresponding liquid storage mechanism to the nozzle through the conductive connector.

[0012] A distance detection module is disposed on the outer surface of the housing and electrically connected to the main control circuit board; the distance detection module is used to detect whether the distance between the nozzle and human skin is a preset distance.

[0013] An image acquisition module, which is disposed on the outer surface of the housing, is used to acquire image signals of human skin or wounds;

[0014] A skin texture detection module, which is disposed on the outer surface of the housing, is used to detect skin texture signals of human skin texture condition;

[0015] The main control circuit board includes a main control module and a wireless module. The input terminals of the main control module are electrically connected to the output terminals of the distance detection module, the image acquisition module, and the skin texture detection module. The output terminals of the main control module are electrically connected to the input terminals of the wireless module and the liquid supply mechanism. The input terminal of the wireless module is electrically connected to the output terminal of the main control module. The main control module is used to control the liquid supply mechanism to supply the medicine to the nozzle through a conductive connector when the distance between the nozzle and the human skin is within a preset distance; or, to receive the image signal and convert it into image information; or, to receive the skin texture signal and convert it into skin texture information. The wireless module is used to transmit the image information to an external detection and analysis module to analyze the image information and form a first preset spraying scheme; or, to transmit the skin texture information to an external detection and analysis module to form a second preset spraying scheme. The external detection and analysis module outputs the first preset spraying scheme or the second preset spraying scheme to the main control module.

[0016] A high-voltage direct current (HVDC) generator, disposed in the mounting cavity, includes a battery and a boost unit. The battery is electrically connected to the liquid supply mechanism, the distance detection module, the input terminal of the boost unit, and the input terminal of the main control module. The boost unit is used to convert the low-voltage DC power supply from the battery into a high-voltage DC power supply. The output terminal of the boost unit has a positive terminal and a negative terminal. The positive terminal is electrically connected to the conductive connector, and the negative terminal is electrically connected to the conductive part.

[0017] According to a second aspect of this application, this application provides a multi-channel electrostatic jet method based on the aforementioned multi-channel electrostatic jet device, comprising:

[0018] The image acquisition module acquires image signals of human skin or wounds and outputs them to the main control module. The main control module receives the image signals and converts them into image information. The wireless module transmits the image information to an external detection and analysis module, which analyzes the image information to form a first preset spraying scheme. The external detection and analysis module then outputs the first preset spraying scheme to the main control module.

[0019] The skin texture detection module detects the skin texture signal of the human skin and outputs it to the main control module. The main control module receives the skin texture signal and converts it into skin texture information. The wireless module transmits the skin texture information to an external detection and analysis module to form a second preset spraying scheme. The external detection and analysis module then outputs the second preset spraying scheme to the main control module.

[0020] When the distance detection module detects that the distance between the nozzle and the human skin is a preset distance, the main control module controls the liquid supply mechanism to supply the liquid medicine to the nozzle through the conductive connector.

[0021] According to the multi-channel electrostatic jet device and method described in the above embodiments, when the distance detection module detects that the distance between the nozzle and the human skin is within a preset distance, the main control module controls the liquid supply mechanism to supply the liquid to the nozzle through a conductive connector. This allows for precise control of the distance between the device and the human skin, ensuring accurate spray deposition onto the target area. An image acquisition module acquires image information of the human skin or wound, which is then analyzed by an external detection and analysis module to form a first preset spray pattern. A skin texture detection module detects skin texture signals, which are then analyzed by the external detection and analysis module to form a second preset spray pattern. Thus, different spray patterns can be generated according to different usage scenarios, making the multi-channel electrostatic jet device versatile and adaptable to various application requirements.

[0029] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

[0030] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0032] This application provides a multi-channel electrostatic jet device and method, mainly applied in fields such as medical aesthetics, wound dressings, and drug sustained release. This multi-channel electrostatic jet device can be operated by a single hand, making it easy to carry and use. The liquid supply mechanism supplies the liquid stored in the storage mechanism to the spraying mechanism, which sprays the liquid out in a filament or mist under the action of a high-voltage DC generator. In this multi-channel electrostatic jet device, a distance detection module detects whether the distance between the nozzle and the human skin is a preset distance. The main control module controls the liquid supply mechanism to supply the liquid to the nozzle through a conductive connector when the distance detection module detects that the distance between the nozzle and the human skin is the preset distance, and the nozzle then sprays the liquid onto the human skin in a filament or mist.

[0033] Example 1

[0034] See Figures 2-5 As shown, this embodiment provides a multi-channel electrostatic jet device, including: a housing 10, a liquid storage mechanism 20, a liquid supply mechanism 30, a jetting mechanism 40, a distance detection module 50, an image acquisition module 51, a skin texture detection module 52, a main control circuit board, and a high-voltage DC power generation mechanism.

[0035] The housing 10 is typically an insulating housing made of insulating material. The housing 10 has a handle 11 for the user to grip. A conductive part 111 is provided in the handle 11, such as... Figure 1 As shown, Figure 1 The rectangular frame set in the handheld part 11 roughly outlines the location and range of the conductive part 111. Figure 1 The positions and ranges shown are only for illustrating the conductive part 111 in this embodiment and do not limit the position and range of the conductive part 111. The housing 10 has an internal mounting cavity 12, in which the aforementioned liquid storage mechanism 20, liquid supply mechanism 30, spray mechanism 40, and high-voltage DC power generation mechanism are all located. In other words, the mounting cavity 12 has mounting positions for mounting the liquid storage mechanism 20, liquid supply mechanism 30, spray mechanism 40, and high-voltage DC power generation mechanism, and these positions are all located in their respective mounting positions within the mounting cavity 12. The distance detection module 50 is located on the outer surface of the housing 10.

[0036] In this embodiment, the housing 10 is composed of a main housing 13, a front panel 14 and a rear cover 15. The hand grip 11 is disposed on the main housing 13. The main housing 13, the front panel 14 and the rear cover 15 form the aforementioned mounting cavity 12.

[0037] The spraying mechanism 40 includes a nozzle 41 and a conductive connector 42. One end of the conductive connector 42 is connected to the nozzle 41. Specifically, the nozzle 41 has a nozzle 411, and the conductive connector 42 has a liquid passage that is connected to the nozzle 411. A liquid storage mechanism 20 is used to store a liquid medicine, which is typically a mixture of a polymer and a solvent. A liquid supply mechanism 30 is connected to both the other end of the conductive connector 42 and the liquid storage mechanism 20. The liquid supply mechanism 30 supplies the liquid medicine from the liquid storage mechanism 20 to the nozzle 41 through the conductive connector 42. The nozzle 411 on the nozzle 41 can spray the liquid medicine. The housing 10 also has a mounting hole 141, which is connected to the receiving cavity 12. The nozzle 41 is mounted in the mounting hole 141. In this embodiment, the mounting hole 141 is located on the front panel 14.

[0038] The distance detection module 50 is disposed on the outer surface of the housing 10. More specifically, the distance detection module 50 is disposed on the front panel 14, and the front panel 14 is provided with mounting holes for mounting the distance detection module 50. The distance detection module 50 is electrically connected to the main control circuit board 70. The distance detection module 50 is used to detect whether the distance between the nozzle 41 and the human skin is a preset distance.

[0039] like Figure 5As shown, the main control circuit board 70 includes a main control module 71. The input terminal of the main control module 71 is electrically connected to the output terminal of the distance detection module 50, and the output terminal of the main control module 71 is electrically connected to the input terminal of the liquid supply mechanism 30. The main control module 71 is used to control the liquid supply mechanism 30 to supply the medicine to the nozzle 41 through the conductive connector 42 when the distance between the nozzle 41 and the human skin is within a preset distance.

[0040] The high-voltage direct current (HVDC) generator includes a battery 61 and a booster unit 62. The battery 61 is preferably a rechargeable battery. The battery 61 is electrically connected to the liquid supply mechanism 30, the distance detection module 50, the input terminal of the booster unit 62, and the input terminal of the main control module 71, providing the necessary power to each mechanism or module. The booster unit 62 converts the low-voltage DC power from the battery 61 into a high-voltage DC power. The output terminal of the booster unit 62 has a positive terminal and a negative terminal. The positive terminal is electrically connected to the conductive connector 42, and the negative terminal is electrically connected to the conductive part 111. Typically, the booster unit 62 can convert the low-voltage DC power from the battery 61 into a high-voltage DC power of several thousand to tens of thousands of volts to meet the application requirements of spinning film formation or electrostatic spraying.

[0041] In practical use, the operator holds the handheld part 11 and, through operation, brings the nozzle 411 of the spray head 41 close to the skin above the operator's skin to be sprayed. Typically, a distance of approximately 5cm to 15cm is maintained between the nozzle 411 and the skin. The operator's hand contacts the conductive part 111, and the negative terminal of the high-voltage DC power supply is connected to the operator through the negative terminal and the conductive part 111, causing the operator's skin surface to carry a negative charge. The liquid supply mechanism 30 supplies the liquid stored in the storage mechanism 20 to the spray head 41 through the conductive connector 42. As the liquid passes through the conductive connector 42, it carries a positive charge under the influence of the high-voltage DC power supply. At this time, a high-voltage electric field is formed between the nozzle 411 and the operator's skin. The positively charged liquid, under the influence of the electric field force, overcomes the surface tension of the liquid and forms filaments or mist that move towards the negative terminal, i.e., the operator's skin surface, forming filamentous fibers or droplets that deposit on the skin surface. Over time, this achieves the purpose of spinning a film or electrostatic spraying.

[0042] Of course, in other embodiments, if an operator is operating on the person being sprayed, the conductive part 111 needs to be electrically connected to the person being sprayed. Then, the operator moves the nozzle close to the skin of the person being sprayed, without the operator's hand touching the conductive part 111. The negative terminal of the high-voltage DC power supply is connected to the person being sprayed through the negative terminal and the conductive part 111, causing the skin surface of the person being sprayed to carry a negative charge. When the liquid medicine passes through the conductive connector 42, it carries a positive charge under the action of the high-voltage DC power supply. At this time, a high-voltage electric field is formed between the nozzle 411 and the skin of the person being sprayed. The positively charged liquid medicine is subjected to the electric field force in this high-voltage electric field, overcomes the surface tension of the liquid, and moves towards the negative terminal, i.e., the skin surface of the person being sprayed, forming filaments or droplets that are deposited on the skin surface of the person being sprayed.

[0043] In this embodiment, when the distance detection module 50 detects that the distance between the nozzle and the human skin is within a preset distance, the main control module 71 controls the liquid supply mechanism 30 to supply the liquid medicine to the nozzle 41 through the conductive connector 42, so as to accurately grasp the distance between the device and the human skin and accurately control the spray deposition to the target area.

[0044] In one embodiment, the multi-channel electrostatic jet device provided in this application further includes: an indicator light, which is installed on the outer surface of the housing 10 and electrically connected to the output terminal of the main control module 71. The indicator light is used to project a first color light spot or a second color light spot onto human skin. The first color light spot is used to indicate that the distance between the nozzle 41 and the human skin is not within a preset distance range, and the second color light spot is used to indicate that the distance between the nozzle 42 and the human skin is within a preset distance range. This is to facilitate the judgment of whether the distance between the nozzle 41 and the human skin detected by the distance detection module is within the preset distance range, and to facilitate the operator's judgment.

[0045] In one embodiment, the liquid storage mechanism 20 and / or the spraying mechanism 40 are detachably installed in the receiving cavity 12. It is understood that the liquid storage mechanism 20 and the spraying mechanism 40 can be an integral structure, or they can be separate structures. In practical use, the separate liquid storage mechanism 20 or the integral liquid storage mechanism 20 and the spraying mechanism 40 can be replaced according to the requirements of the desired liquid.

[0046] Accordingly, for ease of replacement, the front panel 14 and the rear cover 15 are detachably mounted on the main housing 13, for example, by means of snap-fit.

[0047] In this embodiment, the conductive connector 42 is made of conductive metal materials such as iron and copper, and the nozzle 41 is made of insulating materials such as plastic.

[0048] In the multi-channel electrostatic jet device provided in this embodiment, a high-voltage DC power supply is formed by a battery 61 and a boost unit 62. On the one hand, the battery's low-power design reduces the overall power consumption of the device, increases its battery life, and allows for multiple reuses. On the other hand, this multi-channel electrostatic jet device is portable and does not require a large-capacity power supply or an external power source. The device is compact and can be used with one hand via the provided handheld part 111, making it easy to operate.

[0049] See Figure 3 As shown, in one embodiment, multiple liquid storage mechanisms 20, liquid supply mechanisms 30, nozzles 41, and conductive connectors 42 are provided, with each liquid storage mechanism 20, each liquid supply mechanism 30, each nozzle 41, and each conductive connector 42 corresponding to one another. The types of medicine stored in each liquid supply mechanism 30 may be the same or different. One liquid supply mechanism 30 is connected to the other end of its corresponding conductive connector 42 and to its corresponding liquid storage mechanism 20, and one end of a conductive connector 42 is connected to the nozzle 41 corresponding to that conductive connector 42.

[0050] See Figure 5 As shown, in another embodiment, multiple liquid storage mechanisms 20, liquid supply mechanisms 30, and conductive connectors 42 are provided, and one nozzle 41 is provided. Each liquid storage mechanism 20, each liquid supply mechanism 30, and each conductive connector 42 corresponds to one another. The types of medicine stored in each liquid supply mechanism 30 may be the same or different. One liquid supply mechanism 30 is connected to the other end of its corresponding conductive connector 42 and to its corresponding liquid storage mechanism 20. One end of each conductive connector 42 is connected to the nozzle 41.

[0051] See Figure 6 As shown, the image acquisition module 51 has its input terminal electrically connected to the output terminal of the main control module 71. The image acquisition module 51 is used to acquire image signals of human skin or wounds. The image acquisition module 51 uses multi-angle shooting to acquire image signals of human skin or wounds. The main control circuit board 70 also includes a wireless module 72, which is electrically connected to the main control module 71. The output terminal of the main control module 71 is also electrically connected to the input terminal of the wireless module and the input terminal of the liquid supply mechanism 30. The main control module 71 and the wireless module 72 can communicate bidirectionally. The main control module 71 is also used to receive image signals and convert them into image information. The wireless module 72 is used to output the image information to an external detection and analysis module, so that the external detection and analysis module can analyze the image information to form a first preset spraying scheme. The external detection and analysis module then outputs the first preset spraying scheme to the main control module 71. The first preset spraying scheme is to supply a first type of liquid to the nozzle, or to supply a combination of different types of liquids to the nozzle according to a first preset supply order and a first preset supply time period.

[0052] In this embodiment, a first preset spraying scheme is formed based on the image information of human skin or wounds acquired by the image acquisition module 51. Specifically, a first type of medication is supplied to the nozzle 42, meaning one type of medication is supplied to the nozzle 41 via the supply mechanism 30, forming a single supply method. A first combination of different types of medications is supplied to the nozzle 41 according to a first preset supply sequence during a first preset supply time period. This first combination of different types of medications refers to at least two different types of medications being supplied to the nozzle 41 via at least two supply mechanisms, forming a mixed supply method.

[0053] In one embodiment, a skin texture detection module 52 is included. The output of the skin texture detection module 52 is electrically connected to the input of the main control module 71. The skin texture detection module 52 is used to detect skin texture signals of the human skin. The skin texture detection module 52 can acquire skin texture signals of the human skin through a contact probe. The main control module 71 is also used to receive skin texture signals and convert them into skin texture information. The wireless module 72 is also used to transmit the skin texture information to an external detection and analysis module, so that the external detection and analysis module can form a second preset spraying scheme. The external detection and analysis module then outputs the second preset spraying scheme to the main control module 71. The second preset spraying scheme is to supply a second type of liquid to the nozzle, or to supply a combination of two different types of liquids to the nozzle according to a second preset supply sequence during a second preset supply time period.

[0054] In this embodiment, a second preset spraying scheme is formed based on the skin texture information detected by the skin texture detection module 52. A second type of liquid is supplied to the nozzle 42, specifically, one type of liquid is supplied to the nozzle 41 via the liquid supply mechanism 30, forming a separate liquid supply method. The second type of liquid may be the same as or different from the first type of liquid. A combination of two different types of liquids is supplied to the nozzle 41 according to a second preset liquid supply sequence during a second preset liquid supply time period. The second combination of two different types of liquids refers to at least two different types of liquids being supplied to the nozzle 41 via at least two liquid supply mechanisms, forming a mixed liquid supply method. Correspondingly, the second combination of two different types of liquids may be the same as, different from, or partially the same as the first combination of two different types of liquids.

[0055] In this embodiment, the image acquisition module 51 and the skin texture detection module 52 can be used individually or in combination. When the image acquisition module 51 and the skin texture detection module 52 are used in combination, the wireless module 72 is also used to output image information and skin texture information to an external detection and analysis module. After detection and analysis by the external detection and analysis module, a third preset spraying scheme is formed. The external detection and analysis module then outputs the third preset spraying scheme to the main control module 71. The third preset spraying scheme is to supply a third type of liquid to the nozzle, or to supply a combination of three different types of liquids to the nozzle according to a third preset supply sequence during a third preset supply time period.

[0056] A third preset spraying scheme is formed based on the image information acquired by the image acquisition module 51 and the skin texture information detected by the skin texture detection module 52. This scheme involves supplying a third type of liquid to the nozzle, specifically, supplying one type of liquid to the nozzle 41 via the liquid supply mechanism 30, forming a separate liquid supply method. This third type of liquid may be the same as or different from the first and second types of liquids. A third combination of different types of liquids is then supplied to the nozzle 41 according to a third preset liquid supply sequence and within a third preset liquid supply time period. This third combination of different types of liquids refers to at least two different types of liquids being supplied to the nozzle 41 via at least two liquid supply mechanisms, forming a mixed liquid supply method. Correspondingly, this third combination of different types of liquids may also be the same as, different from, or partially the same as the first and second combinations of different types of liquids.

[0057] In this embodiment, the external detection and analysis module can be software running on a mobile phone or computer. Correspondingly, the mobile phone or computer is equipped with a corresponding receiving module to receive image information acquired by the image acquisition module 51 or skin texture information detected by the skin texture detection module 52, which is sent through the wireless module 72.

[0058] In one embodiment, the external detection and analysis module can generate the optimal spraying scheme by comparing image information with skin texture information based on big data analysis.

[0059] See also Figure 6As shown, the main control circuit board 70 also includes a power management module 73 and a drive control module 74. The input terminal of the power management module 73 is electrically connected to the battery 61, and the output terminal of the power management module 73 is electrically connected to the input terminals of the main control module 71, the drive control module, the wireless module, and other electrical loads. The power management module 73 is used for the charging / discharging management of the entire device. Each electrical load needs to obtain power from the battery 61 through the power management module 73. The input terminal of the drive control module 74 is electrically connected to the output terminal of the main control module 71, and the output terminal of the drive control module 74 is electrically connected to the liquid supply mechanism 30. The drive control module 74 is used to adjust the voltage output from the battery 61 to the liquid supply mechanism 30 to control the output power of the liquid supply mechanism 30, thereby adjusting the rate at which the liquid in the liquid storage mechanism 30 is supplied to the nozzle 41 through the conductive connector 42, that is, adjusting the amount of liquid supplied to the nozzle 42, so as to facilitate the control of the electrostatic spray volume, so as to accurately control the filament output or spray and achieve directional deposition.

[0060] In one embodiment, the liquid supply mechanism 30 includes a peristaltic pump 31 and a connecting hose 32, and the liquid storage mechanism 20 includes a storage tank for storing the liquid. One end of the connecting hose 32 is connected to the storage tank, and the other end of the connecting hose 32 is connected to a conductive connector 42. The peristaltic pump 31 is used to squeeze the connecting hose 32 to supply the liquid to the nozzle 41 through the conductive connector 42. The aforementioned drive control module 74 is electrically connected to the peristaltic pump 31. By adjusting the output voltage, the drive control module 74 can adjust the rotation speed of the peristaltic pump 31, thereby adjusting the amount of liquid supplied to the nozzle 42. This facilitates the control of the electrostatic spray volume, enabling precise control of filament output or spraying, and achieving directional deposition.

[0061] In one embodiment, the liquid storage mechanism 20 includes a flexible liquid storage tank for storing liquid medicine. The flexible liquid storage tank is deformable and can be reset. The flexible liquid storage tank is connected to the conductive connector 42 via a pipeline. The liquid supply mechanism 30 includes a compression drive motor, a lead screw, a lead screw nut, a compression block, a positioning block, a slider, and a guide rail. The guide rail is arranged parallel to the lead screw, and the slider is slidably mounted on the guide rail. The motor shaft of the compression drive motor is connected to the lead screw, the lead screw nut is screwed onto the lead screw, the compression block is mounted on the lead screw nut, and the compression block is fixedly connected to the slider. The positioning block is located at the end of the lead screw, and the aforementioned flexible liquid storage tank is located below the positioning block, that is, the flexible liquid storage tank is located between the positioning block and the compression block. The compression drive motor drives the lead screw to rotate, and the lead screw nut converts the rotational motion of the lead screw into linear motion along the axial direction of the lead screw, so that the compression block compresses the flexible liquid storage tank. During the compression process, the liquid medicine enters the conductive connector and is then supplied to the nozzle through the conductive connector. The aforementioned drive control module is electrically connected to the extrusion drive motor. Adjusting the speed of the extrusion drive motor regulates the amount of liquid supplied to the nozzle 42, thus facilitating control of the electrostatic spray volume for precise control of filament output or spraying, achieving directional deposition.

The drive control module adjusts the output voltage to adjust the speed of the geared motor, thereby adjusting the amount of liquid supplied to the nozzle 42. This facilitates the control of the electrostatic spray volume, enabling precise control of filament output or spraying, and achieving directional deposition.

[0065] In one embodiment, each switch may be a push-button switch or a rotary switch. In this embodiment, push-button switches are preferred.

[0066] In one embodiment, a conductive coating is provided on the housing 10, which is formed as a conductive portion 111.

[0067] In one embodiment, the main control circuit board 70 further includes a safety protection module. The output terminal of the safety protection module is electrically connected to the input terminal of the main control module 71. The safety protection module is used to cut off the high-voltage DC power output of the boost unit when a person touches both the positive and negative connection terminals at the same time, which can effectively avoid the discomfort caused by electric shock to the operator.

[0070] Example 2

[0071] This embodiment provides a multi-channel electrostatic jet method, which is based on the multi-channel electrostatic jet device in Embodiment 1. (See also...) Figure 1 As shown, the multi-channel electrostatic jet method includes:

[0072] Collect image signals of skin texture or wounds, or detect skin texture signals of skin condition, and generate a first preset spraying scheme or a second preset spraying scheme.

[0073] Specifically, the image acquisition module 51 acquires image signals of human skin or wounds and outputs these signals to the main control module 71. The main control module 71 receives the image signals and converts them into image information. The wireless module 72 transmits the image information to an external detection and analysis module, which analyzes the image information to form a first preset spraying scheme. The external detection and analysis module then outputs the first preset spraying scheme back to the main control module 71. The skin texture detection module 52 detects skin texture signals of the human skin and outputs them to the main control module 71. The main control module 71 receives the skin texture signals and converts them into skin texture information. The wireless module 72 transmits the skin texture information to an external detection and analysis module, which forms a second preset spraying scheme. The external detection and analysis module then outputs the second preset spraying scheme back to the main control module 71.

[0074] The detection module 50 detects whether the distance between the nozzle 41 and the human skin is at a preset distance. Specifically, it detects the distance between the nozzle 41 and the human skin. More specifically, it detects the distance between the nozzle 41 and the human skin as a preset distance through the distance detection module 50.

[0075] The liquid supply mechanism supplies the medicine to the nozzle through a conductive connector. Specifically, when the distance detection module 50 detects that the distance between the nozzle 41 and the human skin is a preset distance, the main control module 71 controls the liquid supply mechanism 30 to supply the medicine to the nozzle 41 through the conductive connector 42. More specifically, under the first preset spray scheme and the second preset spray scheme, the requirement that the distance between the nozzle and the human skin should be at a preset distance must be met.

[0076] In the multi-channel electrostatic spraying method provided in this embodiment, the image acquisition module 51 and the skin texture detection module 52 can be used simultaneously to generate a third preset spraying scheme. Specifically, the image acquisition module 51 outputs the acquired image signal to the main control module 71, while the skin texture detection module 52 transmits the detected skin texture signal to the main control module 71. The main control module 71 converts the image signal and skin texture signal into image information and skin texture information, and outputs them to an external detection and analysis module. After analysis by the external detection and analysis module, the third preset spraying scheme is formed. Similarly, under the third preset spraying scheme, the requirement that the nozzle and human skin be at a preset distance should also be met.

[0077] In one embodiment, the external detection and analysis module can generate the optimal spraying scheme by comparing image information with skin texture information based on big data analysis.
