Description

Technical Field

[0001] This utility model relates to the field of sealing equipment technology, and more specifically, to an automatic sealing device. Background Technology

[0002] In fields such as medical testing and pathology, traditional solutions for automated slide sealing devices suffer from the following core problems:

[0003] Limitations of slide transport and clamping

[0004] Existing devices mostly use electric push rods or spring grippers to directly hold the glass slides. For example, prior art document CN222299684U (publication number: CN222299684U, application date: 2024.03) discloses a device for extracting coverslips using a suction cup structure, but it does not mention the method of transporting the glass slides. Traditional transport methods suffer from unstable clamping force, which can easily lead to slide displacement or breakage. Furthermore, they cannot be synchronized with processes such as dispensing and covering, resulting in low efficiency.

[0005] The comparative document CN222299684U improves the separation problem of coverslips through a horizontal sliding adsorption mechanism and height difference design, but its vertical adsorption method may still lead to the following shortcomings: when the vacuum suction cup is vertically extracted, the static electricity or friction between the coverslips can easily cause multiple adsorptions, requiring manual intervention; when applying, direct pressing cannot effectively expel air from the adhesive, affecting microscopic observation; and two-dimensional motion mechanisms (such as XY axis translation) are difficult to accurately align with the adhesive application area. Utility Model Content

[0006] The purpose of this invention is to provide an automatic slide sealing device to solve the problems of unstable clamping force, easy slip displacement or breakage, and low efficiency caused by the traditional transmission method mentioned in the background art, which cannot be synchronized with processes such as dispensing and cover slip.

[0007] To achieve the above objectives, this utility model provides an automatic slide sealing device, including a lifting mechanism for clamping and lifting a staining rack so that the slides in the staining rack sequentially reach the sealing motion plane.

[0008] The X1 mechanism is equipped with a slide pusher tongue for horizontally pushing the slide out of the staining rack;

[0009] The X2 mechanism is equipped with a push block and a counterweight. The push block is connected to the counterweight by a steel wire rope. The glass slide is held by the weight of the counterweight and the push plate tongue plate.

[0010] The YZ mechanism, including a Y-axis horizontal movement mechanism and a Z-axis lifting mechanism, is used to extract the coverslip from the coverslip box and attach it to the adhesive area of ​​the slide.

[0011] The dispensing mechanism is equipped with switchable dispensing position, washing position, discharging position and dispensing head detection sensor, which is used to dispense glue during the movement of the glass slide;

[0012] The slide sealing station is used to support glass slides and assist in completing the slide sealing process.

[0013] The device uses a lifting mechanism to hold the staining rack and raise and lower the slides one by one. The X1 mechanism pushes the slide tongue horizontally out of the rack. The X2 mechanism uses the weight of the counterweight and the pusher tongue to hold the slide in place. The YZ mechanism uses two-dimensional motion to extract and attach the cover slide. The dispensing mechanism applies adhesive during the movement. The sealing station supports the slide to complete the sealing process. All mechanisms work together through sensors and motor drives to achieve a fully automated cycle from slide ejection, dispensing adhesive, cover slide application to return.

[0014] Preferably, the lifting mechanism includes a gripper free end and a gripper connecting plate, both of which are fixed to the lifting slider by a slider connecting plate and are driven by a motor to move up and down along the lifting guide rail.

[0015] In this configuration, the free end of the gripper and the gripper connecting plate are fixed to the lifting slider via the slider connecting plate. The motor drives the slider to move up and down along the guide rail, thereby clamping the staining rack and adjusting the height of the slides so that they sequentially reach the sealing motion plane.

[0016] Preferably, the pusher tongue of the X1 direction mechanism is fixed to the X1 direction slider by the tongue connecting plate, and is driven by the motor to extend and retract horizontally along the X1 direction guide rail. An X1 direction in-situ sensor and a running position sensor are provided in the direction of movement.

[0017] In this configuration, the slide pusher tongue is fixed to the X1 slider via a tongue connecting plate. The motor drives the slider to extend and retract horizontally along the guide rail. The sensor detects the original position and running position in real time to ensure that the slide pusher tongue accurately pushes out the glass slide.

[0018] Preferably, the push block of the X2 mechanism is connected to the push slider through the push block connecting plate and moves along the push guide rail. One end of the wire rope is fixed to the push block connecting plate through the wire rope connecting plate, and the other end passes around the pulley and is connected to the counterweight. The counterweight moves up and down along the counterweight guide rod by gravity and external force. A counterweight in-situ detection sensor is provided on the outside of the counterweight.

[0019] In this configuration, the push block is connected to the push slider via a connecting plate. One end of a steel wire rope is fixed to the push block connecting plate, and the other end passes over a pulley and connects to the counterweight. The counterweight pulls the push block down along the guide rod under the influence of gravity, forming a clamping force with the push plate tongue. A sensor detects the original position of the counterweight to ensure the accuracy of the push block's movement.

[0020] Preferably, the Z-axis lifting mechanism of the YZ-axis mechanism is equipped with a suction cup fixing head, which is connected to the Z-axis slider via a connecting rod and moves up and down along the Z-axis guide rail. The bottom of the suction cup fixing head is an arc surface and is equipped with a vacuum suction cup and a cover glass detection sensor. The Y-axis horizontal movement mechanism is fixed to the Y-axis slider via a lifting connecting plate and front and rear connecting plates, moves back and forth along the Y-axis guide rail, and is equipped with a Y-axis in-situ sensor. A cover glass box and a fragment box are arranged along the movement path. The Z-axis lifting mechanism is equipped with a Z-axis in-situ detection sensor for Z-axis in-situ detection and a Z-axis maintenance position detection sensor for Z-axis maintenance position detection. The maintenance position is equipped with a Z-axis maintenance limiting post.

[0021] This setup includes a Z-axis lifting mechanism connected to a suction cup holder via a connecting rod, which moves up and down along a guide rail. The curved surface at the bottom of the suction cup holder engages with the vacuum suction cup and sensor to extract the coverslip. The Y-axis horizontal movement mechanism is fixed to the slider via a connecting plate and moves back and forth along the guide rail, moving the suction cup holder between positions such as the coverslip box and the sealing position. The Z-axis also includes in-situ and inspection position sensors, along with limit posts for easy maintenance.

[0022] Preferably, the arc surface of the suction cup fixing head makes rolling contact with the coverslips in the coverslip box, and the extraction of a single coverslip is achieved by sequentially opening / releasing the vacuum suction cup, and the air bubbles are expelled during the covering process by rolling and pressing.

[0023] This feature allows the curved surface of the suction cup fixing head to roll into contact with the coverslip inside the coverslip box. By sequentially opening / releasing the vacuum suction cup, the tension of the coverslip is used to separate individual coverslips. During application, the rolling motion presses the cover glass, gradually expelling air from the adhesive.

[0024] Preferably, the dispensing head of the dispensing mechanism is equipped with a dispensing solenoid valve and a dispensing needle, which together with the glue storage bottle and glue tube form a glue dispensing liquid path. At the same time, the glue storage bottle is connected to the air pump through an air tube and a proportional control valve to form a glue dispensing pressure air path. The dispensing head can switch between a dispensing position, a washing position and a discharging position. The washing position is equipped with a washing bottle, and the discharging position is equipped with a glue holding bottle.

[0025] This setting features an internal solenoid valve controlling glue dispensing in the dispensing head, with the liquid and air circuits operating independently. The air pump provides stable dispensing pressure through a proportional control valve. The dispensing head can switch between dispensing, washing, and discharging positions. The washing position soaks the needle to prevent glue from solidifying, while the discharging position removes residual glue.

[0026] Preferably, the sealing station is equipped with a sealing table, with fixed slide guide wheels and movable slide guide wheels on both sides. The movable slide guide wheels are fixed on the guide wheel bracket, and an X2 in-situ detection sensor is provided at the left end of the sealing table.

[0027] Fixed wheels and movable wheels are installed on both sides of the sealing stage. The movable wheels press the slide against the fixed wheels to correct its position. The sensor detects the original position of the X2 mechanism to ensure accurate positioning when the slide reaches the sealing position.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] In this automatic slide sealing device, a counterweight and a slide pusher tongue work together to form a stable clamping force, preventing slide misalignment or breakage, simplifying mechanical transmission, and reducing the failure rate. The X1 and X2 mechanisms clamp the slides synchronously, enabling coordinated operation with processes such as dispensing and cover slip preparation, thus improving process continuity.

[0030] The vacuum suction cup makes rolling contact with the coverslip to remove the slide, reducing the problem of slide stacking; during application, rolling and pressing removes air, improving the clarity of microscopic observation. The Y-axis and Z-axis mechanisms work in conjunction with the sensor to calibrate the position, ensuring precise alignment of the coverslip and the adhesive-coated area of ​​the slide.

[0031] The dispensing head can be switched between different workstations. Soaking the needle in the dispensing station prevents the adhesive from solidifying, reducing maintenance frequency and consumable costs. The dispensing pressure is precisely adjustable to support various dispensing needs and ensure consistent sealing quality. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] This utility model provides an automatic sealing device, such as... Figure 1 As shown, it includes a lifting mechanism 1, which is used to clamp and lift the staining rack 13 so that the slides in the staining rack 13 reach the sealing motion plane in sequence.

[0042] X1 is a sliding tongue plate 21 provided with a slide pusher 21 for horizontally pushing the glass slide out of the staining rack 13;

[0043] The X2 mechanism 3 is equipped with a push block 31 and a counterweight 35. The push block 31 is connected to the counterweight 35 by a steel wire rope 33. The glass slide is clamped by the weight of the counterweight 35 and the push plate tongue 21.

[0044] YZ mechanism 4, including Y horizontal movement mechanism and Z lifting mechanism, is used to extract cover glass from cover glass box 49 and attach it to the adhesive area of ​​glass slide.

[0045] The dispensing mechanism 5 is equipped with a switchable dispensing position 51, a washing position 52, a discharging position 53, and a dispensing head detection sensor 57, which is used to dispense glue during the movement of the glass slide.

[0046] Sealing station 6 is used to support glass slides and assist in completing the sealing process.

[0047] The device uses a lifting mechanism 1 to clamp and lift the staining rack 13 slide by slide. The X1-direction mechanism 2's pusher tongue 21 pushes the slide horizontally. The X2-direction mechanism 3's pusher block 31 is connected to a counterweight block 35 via a steel wire rope 33, relying on the weight of the counterweight block 35 and the pusher tongue 21 to clamp the slide. The YZ-direction mechanism 4 uses horizontal movement in the Y direction and lifting in the Z direction to extract and attach coverslips from the coverslip box 49 using a suction cup fixing head 41. The dispensing mechanism 5's dispensing head 54 switches between dispensing positions 51 and washing positions 52 for dispensing adhesive. The sealing station 6's sealing table 61 supports the slides to complete the process. Each mechanism operates in coordination with sensors such as the X1-direction in-situ sensor 25 and the Z-direction in-situ detection sensor 410, and motor drives. The system integrates multiple components such as lifting mechanism 1, X1 / X2 and cover mechanism 2 / 3 to automate the entire sealing process and reduce manual intervention. Each mechanism works together through a numbered structure to ensure the continuity of slide transfer, dispensing, and cover plate application, thereby improving sealing efficiency.

[0048] In this embodiment, as Figure 1 As shown, the lifting mechanism 1 includes a gripper free end 11 and a gripper connecting plate 12, both of which are fixed to the lifting slider 15 by a slider connecting plate 14, and are driven by a motor to move up and down along the lifting guide rail 16.

[0049] The free end 11 of the gripper of the lifting mechanism 1 and the gripper connecting plate 12 are fixed to the lifting slider 15 via the slider connecting plate 14. The motor drives the lifting slider 15 to move up and down along the lifting guide rail 16, clamping the staining rack 13 and adjusting the height of the slides to the sealing motion plane. The lifting slider 15 and the guide rail 16 work together to precisely control the lifting of the staining rack 13, ensuring that the slides reach the designated height in sequence; the clamping structure of the free end 11 of the gripper and the connecting plate 12 is stable, preventing the staining rack from shaking and causing the slides to shift.

[0050] Specifically, such as Figure 2 As shown, the pusher tongue plate 21 of the X1 direction mechanism 2 is fixed on the X1 direction slider 23 through the tongue plate connecting plate 22. It is driven by the motor to extend and retract horizontally along the X1 direction guide rail 24, and an X1 direction in-situ sensor 25 and a running position sensor 26 are provided in the direction of movement.

[0051] The slide pusher tongue 21 of the X1 direction mechanism 2 is fixed to the X1 direction slider 23 via the tongue connecting plate 22. The motor drives the X1 direction slider 23 to extend and retract horizontally along the X1 direction guide rail 24. The X1 direction in-situ sensor 25 and the running position sensor 26 detect the slider position in real time to ensure that the slide pusher tongue 21 accurately pushes out the glass slide. The transmission structure between the X1 direction slider 23 and the guide rail 24 ensures precise slide pushing action, and the sensors 25 / 26 prevent over- or under-pushing of the slide; the horizontal extension and retraction of the slide pusher tongue 21 pushes the glass slide, reducing the risk of breakage during transmission.

[0052] Furthermore, such as Figure 3 As shown, the push block 31 of the X2 mechanism 3 is connected to the push slider 37 through the push block connecting plate 32 and moves along the push guide rail 38. One end of the wire rope 33 is fixed to the push block connecting plate 32 through the wire rope connecting plate 36, and the other end passes around the pulley 34 and is connected to the counterweight 35. The counterweight 35 moves up and down along the counterweight guide rod 310 by gravity and external force. The counterweight 35 is equipped with a counterweight in-situ detection sensor 39 on the outside of the counterweight 35.

[0053] The push block 31 of mechanism 3 is connected to the push slider 37 via the push block connecting plate 32 and moves along the push guide rail 38. One end of the wire rope 33 is fixed to the connecting plate 32 via the wire rope connecting plate 36, and the other end passes over the pulley 34 and connects to the counterweight 35. The counterweight 35 pulls the push block 31 down along the counterweight guide rod 310 under gravity, forming a clamping force with the pusher tongue plate 21. The counterweight in-situ detection sensor 39 monitors the position of the counterweight. The gravity of the counterweight 35 provides a continuous clamping force through the wire rope 33, avoiding fluctuations in the force of the electric clamping and realizing lossless transmission of the glass slide. The push slider 37 cooperates with the guide rail 38 to ensure the movement accuracy of the push block 31 and reduce the probability of mechanical failure.

[0054] Furthermore, such as Figure 5 , Figure 6 As shown, the Z-axis lifting mechanism of the YZ-axis mechanism 4 is equipped with a suction cup fixing head 41, which is connected to the Z-axis slider 43 through a connecting rod 42 and moves up and down along the Z-axis guide rail 44. The bottom of the suction cup fixing head 41 is an arc surface, and a vacuum suction cup 414 and a cover glass detection sensor 412 are provided. The Y-axis horizontal movement mechanism is fixed on the Y-axis slider 47 through a lifting connecting plate 45 and a front and rear connecting plate 46, and moves back and forth along the Y-axis guide rail 48. It is equipped with a Y-axis in-situ sensor 415. A cover glass box 49 and a fragment box 413 are provided on the movement path. The Z-axis lifting mechanism is equipped with a Z-axis in-situ detection sensor 410 for Z-axis in-situ detection and a Z-axis maintenance position detection sensor 411 for Z-axis maintenance position detection. A Z-axis maintenance limit pin 416 is provided at the maintenance position.

[0055] The Z-axis lifting mechanism of the YZ-axis mechanism 4 is connected to the suction cup fixing head 41 via the connecting rod 42 and moves up and down along the Z-axis guide rail 44. The bottom arc surface of the suction cup fixing head 41 is equipped with a vacuum suction cup 414 and a cover glass detection sensor 412 for extracting the cover glass. The Y-axis horizontal movement mechanism is fixed on the Y-axis slider 47 via the lifting connecting plate 45 and the front and rear connecting plates 46 and moves back and forth along the Y-axis guide rail 48. A cover glass box 49 and a fragment box 413 are set along the path. The Z-axis is equipped with an in-situ detection sensor 410 and a maintenance position detection sensor 411, which work together with the limit pin 416 to achieve maintenance positioning.

[0056] The two-dimensional movement of the Y-axis slider 47 and guide rail 48, and the Z-axis slider 43 and guide rail 44, ensures that the suction cup fixing head 41 accurately positions the cover glass box 49 and the sealing position; the maintenance position sensor 411 and the limit pin 416 facilitate equipment maintenance and improve the ease of operation.

[0057] Furthermore, such as Figure 5 As shown, the arc surface of the suction cup fixing head 41 rolls into contact with the coverslip inside the coverslip box 49. The single coverslip is extracted by the sequential opening / releasing of the vacuum suction cup 414, and air bubbles are expelled during the covering process by rolling and pressing.

[0058] The arc-shaped surface of the suction cup fixing head 41 rolls into contact with the coverslips inside the coverslip box 49. By sequentially opening / releasing the vacuum suction cup 414, the tension of the coverslips separates individual coverslips. During application, the arc-shaped surface rolls and presses along the slide, gradually expelling air from the adhesive. The arc-shaped surface, in conjunction with the vacuum suction cup 414, reduces the probability of multiple coverslips overlapping to below 1% during rolling and pressing; the rolling and pressing action expels air bubbles through the arc-shaped surface structure.

[0059] Furthermore, such as Figure 4 As shown, the dispensing head 54 of the dispensing mechanism 5 is equipped with a dispensing solenoid valve and a dispensing needle 541, which together with the glue storage bottle and glue tube form a glue dispensing liquid path. At the same time, the glue storage bottle is connected to the air pump through the air tube and the proportional control valve to form a glue dispensing pressure air path. The dispensing head 54 can switch between the dispensing position 51, the glue washing position 52 and the glue discharge position 53. The glue washing position 52 is equipped with a glue washing bottle 55, and the glue discharge position 53 is equipped with a glue holding bottle 56.

[0060] The dispensing head 54 of the dispensing mechanism 5 contains a dispensing solenoid valve and a dispensing needle 541, which, together with the glue storage bottle and glue tubing, form a liquid circuit. The glue storage bottle, through an air tube and a proportional control valve, forms a pressurized air circuit with an air pump. The dispensing head 54 can switch between dispensing position 51, glue washing position 52, and glue discharge position 53. In the glue washing position 52, the glue washing bottle 55 soaks the needle, and in the glue discharge position 53, the glue collection bottle 56 collects residual glue. Multi-position switching, such as the glue washing position 52, avoids glue solidification in the dispensing needle 541, reducing maintenance costs by 80%. The pressurized air circuit precisely controls the glue dispensing volume through the proportional control valve.

[0061] Furthermore, such as Figure 1 As shown, the sealing station 6 is equipped with a sealing table 61, with glass slide guide fixed wheels 62 and glass slide guide movable wheels 63 on both sides. The glass slide guide movable wheels 63 are fixed on the guide wheel bracket 64, and an X2 in-situ detection sensor 65 is provided at the left end of the sealing table 61.

[0062] The sealing stage 61 at the sealing station 6 is equipped with slide guide wheels 62 and movable wheels 63 on both sides. The movable wheels 63 are fixed on the guide wheel bracket 64, pressing the slide to the correction position of the fixed wheels 62. The X2 in-situ detection sensor 65 at the left end of the sealing stage 61 detects the original position of the push block 31 to ensure the slide is positioned. The guide wheels 62 and movable wheels 63 work together to ensure the linear movement of the slide on the sealing stage 61 and avoid deviation; the X2 in-situ detection sensor 65 assists in positioning and provides a precise reference for the cover plate action.

[0063] When the automatic sealing device of this utility model is in use, after receiving the start command, the system initiates a self-test program, and each moving mechanism returns to its original position: X1 direction mechanism 2, X2 direction mechanism 3, and YZ direction mechanism 4 return to their original positions, and the dispensing head 54 moves to the dispensing position 51. Simultaneously, the system detects signals from key sensors, including X1 direction home position sensor 25, X2 direction home position sensor 65, Y direction home position sensor 415, Z direction home position sensor 410, and dispensing position sensor 57, to ensure normal signals; a set positive air pressure is established in the glue storage bottle, and the coverslip box 49 and its coverslips are in place. After the self-test passes, the device enters the sealing standby state, waiting for the staining rack to load.

[0064] When the lifting mechanism 1 clamps the staining rack 13 to the workstation, the control system acquires the position information of the staining rack and issues a sealing command. The slide pusher 21 of the X1-direction mechanism 2 moves forward from the original position determined by the X1-direction in-situ sensor 25, pushing the slides at the same height level on the staining rack 13 forward horizontally. During the pushing process, the slide contacts and pushes the push block 31 of the X2-direction mechanism 3 forward together. The push block 31 pulls the counterweight 35 to rise synchronously through the steel wire rope 33. At this time, under the combined action of the pushing force of the slide pusher 21 and the gravity of the counterweight 35, the slide is stably clamped between the slide pusher 21 and the push block 31.

[0065] When the X1-direction mechanism 2 reaches the sensor 26 that triggers the running position detection, the X2-direction mechanism 3 simultaneously moves away from the sensor 65 that detects the original position of the X2-direction mechanism. The system uses the combined signal from the sensor 26 and the sensor 65 to determine whether the staining rack 13 is empty or whether the X1-direction mechanism 2 and the X2-direction mechanism 3 are malfunctioning or stuck. If the slide is pushed out normally, when it reaches the dispensing position 51 of the dispensing mechanism 5, the control system issues a dispensing command, activating the dispensing solenoid valve inside the dispensing head 54. Under the pressure of the glue reservoir, the dispensing needle 541 injects the glue onto the slide. When the set dispensing end position is reached, the dispensing solenoid valve closes, stopping the dispensing.

[0066] As the slide moves toward the sealing position, the YZ-direction mechanism 4 is activated in advance. The Y-direction horizontal movement mechanism, through the lifting connecting plate 45 and the front and rear connecting plates 46, drives the suction cup fixing head 41 of the Z-direction lifting mechanism forward along the Y-direction guide rail 48 to above the coverslip box 49. Subsequently, the connecting rod 42 of the Z-direction lifting mechanism drives the suction cup fixing head 41 to descend along the Z-direction guide rail 44. The arc surface at the bottom of the suction cup fixing head 41 rolls into contact with the coverslips inside the coverslip box 49. By sequentially activating the vacuum suction cups 414, the tension of the coverslips is used to separate and adsorb individual coverslips.

[0067] After the suction cup fixing head 41 lifts the coverslip, it rises, and the Y-axis mechanism moves it through the fragment box 413. If the coverslip is broken, it can be discarded here. It then moves to above the sealing position. Next, the Z-axis mechanism descends again, and the arc surface of the suction cup fixing head 41 rolls and presses against the slide. During the descent, the vacuum suction cups 414 are released sequentially, placing the coverslip onto the adhesive area of ​​the slide. Simultaneously, the rolling motion squeezes out air from the adhesive, completing the sealing action. After sealing, the suction cup fixing head 41 rises back to its original Y-axis position.

[0068] The X1-direction mechanism 2 and X2-direction mechanism 3 continue to hold the covered slide and push it back to its original position in the staining rack 13. During the pushback process, the system uses signals from sensors 26 and 65 to determine if the slide is stuck during the return process. Once the slide is successfully pushed back to the staining rack 13, both the X1-direction mechanism 2 and X2-direction mechanism 3 return to their original positions, completing the current slide sealing process.

[0069] After sealing one slide, the lifting mechanism 1 raises the staining rack 13 a set distance, ensuring the next slide is at the same height as the slide pusher 21 and on the same plane of motion. The control system then issues another sealing command, repeating the slide pushing, gluing, cover slip, and push-back sequence until the entire rack of slides is sealed. At this point, the lifting mechanism 1 lowers and releases the staining rack, and the equipment returns to the sealing standby state, waiting for the next staining rack to load, thus achieving a continuous sealing workflow.

[0070] During the above-mentioned work process, the motion parameters of each mechanism (such as lifting distance, slide push stroke, glue dispensing position, etc.) can be adjusted and set through the control system to adapt to the needs of different specifications of glass slides and sealing slides, and ensure efficient and stable operation of the sealing work.

[0071] Finally, it should be noted that the electronic components in the lowering mechanism 1, X1 direction mechanism 2, X2 direction mechanism 3, YZ direction mechanism 4, etc. in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order between each electrical component in the above working principle to complete the electrical connection. All of these are technologies known in the art.

[0072] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
