[0027] See also Figure 1 and 2 The present invention provides an electric energy meter, comprising: a meter body 1, on which a card insertion port 11 and a dust exhaust port 12 are provided; a guide component 2, which is installed in the meter body 1 and is connected to the card insertion port 11, so as to guide the power purchase card inserted into the card insertion port 11 toward the inner side of the meter body 1; an isolation component 3, on one side of which a reading port 31 is provided, and the isolation component 3 is installed in the meter body 1, so as to isolate the power purchase card when the guide component 2 is input into the isolation component 3, and to perform self-cleaning when the power purchase card exits the isolation component 3, and to discharge the cleaned dust from the dust exhaust port 12; and a card reader component 4, which is installed in the meter body 1 and movably arranged in the reading port 31, so as to perform mobile identification and card reading on the power purchase card inserted into the isolation component 3.

[0028] It is not difficult to find from the above content that in the electric energy meter provided by the present invention, in the process of inserting the power purchase card into the electric energy meter to purchase electricity, the power purchase card is inserted from the card insertion port 11 on the meter body 1. When the power purchase card enters the transmission component 2 from the card insertion port 11, the transmission component 2 will sense the power purchase card, and then drive the power purchase card to continue to move toward the isolation component 3 under the drive of the transmission component 2. Specifically, when the transmission component 2 contacts the power purchase card, it can collect the pressure signal of the power purchase card when it contacts through, for example, a pressure sensor, and then drive the power purchase card to move toward the isolation component 3. When the power purchase card moves further, it will reach the card reading area of ​​the card reader component 4 under the isolation effect of the isolation component 3. And after the power purchase card reaches the card reading area of ​​the card reader component 4, the card reader component 4 will automatically move back and forth around the power purchase card chip to automatically move and search for the location of the power purchase card chip, thereby facilitating the rapid search for the power purchase card chip and performing the card reading operation. After the electricity purchase card is identified and the electricity is purchased, the transmission component 2 will further transmit the electricity purchase card in the reverse direction, thereby withdrawing the electricity purchase card. At the same time, the isolation component 3 will automatically clean the surface of the electricity purchase card inside and discharge it from the dust outlet 12. Through the above isolation method, the card insertion space and the card reading and identification area of ​​the card reader component 4 can be protected to prevent dust, water, etc. on the electricity purchase card from entering the card insertion space and the card reading and identification area of ​​the card reader component 4, thereby affecting the further use of the card reader component 4, such as causing the internal moisture of the electric energy meter after being wetted by water; and it will also affect the further use of the electricity purchase, for example, when there are pollutants such as particles in the card insertion space, the surface of the electricity purchase card will be scratched and damaged when the card is inserted again. Specifically, the electricity purchase card can be a contactless IC card. Moreover, when the electricity purchase card is inserted into the card insertion space, by performing mobile identification and card reading by the card reader component 4 when reading the electricity purchase card, the reading ability of the card reader component 4 for the electricity purchase card can be effectively enhanced, thereby solving the problem that the electricity purchase card is difficult to accurately correspond to the card reading identification area of ​​the card reader component 4 due to limited card insertion space, and improving the electricity purchasing efficiency of the electricity purchase card.

[0029] like Figure 4 As shown, the guide assembly 2 includes: a guide seat 21, on which a guide channel 22 is provided; and a guide wheel 23, which is provided in the guide channel 22 to contact with both sides of the inserted power purchase card to drive the power purchase card to move back and forth along the guide channel 22; wherein the guide wheel 23 is an elastic wheel.

[0030] In one embodiment of the present invention, when the power purchase card reaches the guide assembly 2 through the card insertion port 11, the power purchase card will contact the guide roller 23 in the guide channel 22, and after the power purchase card contacts the guide roller 23, the guide roller 23 will rotate to drive the power purchase card to pass through the guide channel 22 to reach the isolation assembly 3, and identify and read the card of the card reader assembly 4 on one side of the isolation assembly 3. In this embodiment, the guide seat 21 is also provided with a synchronous gear box and a servo motor for driving the guide roller 23 to rotate, and the power output end of the synchronous gear box is connected to each guide roller 23, and the power output end of the servo motor is connected to the power input end of the synchronous gear box, so that the guide roller 23 driven by the synchronous gear box can be driven by the servo motor to rotate, thereby moving with the power purchase card.

[0031] It is worth noting that when the electricity purchase card is inserted into the guide channel 22, in order to determine the arrival signal of the electricity purchase card, a pressure sensor is also installed on the guide wheel 23, so that when the electricity purchase card is inserted, it can contact the pressure sensor, and then control the servo motor through the controller according to the pressure information to drive the guide wheel 23 driven by the synchronous gear box to rotate, so as to drive the electricity purchase card to move.

[0032] like Figure 4 and Figure 5 As shown, the isolation component 3 includes: an isolation bracket 32, which is located below the conveying component 2, and an isolation channel 35 is provided on the top of the isolation bracket 32, and the top of the isolation channel 35 corresponds to the output direction of the power purchasing card; an isolation membrane component 33, which is elastically installed on both sides of the top of the isolation bracket 32, so that the conveying component 2 carries the power purchasing card to push the isolation membrane component 33 toward the isolation channel 35 for isolation, and when the power purchasing card exits the isolation channel 35, the isolation membrane component 33 automatically exits the isolation channel 35; and a scraper component 34, which is installed on one side of the isolation bracket 32, one side of the scraper component 34 is attached to the surface of the isolation membrane component 33, and the other side of the scraper component 34 is correspondingly arranged at the dust exhaust port 12, so that when the isolation membrane component 33 exits the isolation channel 35, the surface of the isolation membrane component 33 is cleaned, and the cleaned dust is discharged from the dust exhaust port 12.

[0033] In one embodiment of the present invention, when the transmission component 2 drives the electricity purchase card to reach the isolation component 3, the electricity purchase card will reach the top of the isolation bracket 32 ​​and correspond to the isolation channel 35. When the electricity purchase card continues to move, it will push the isolation film component 33 to move toward the isolation channel 35 until the electricity purchase card reaches the card reading and identification area of ​​the card reader component 4. In addition, when the electricity purchase card reaches the card reading and identification area of ​​the card reader component 4, the isolation film component 33 is in an elastic energy storage state. Subsequently, when the electricity purchase is successful and the electricity purchase card leaves the isolation channel 35 of the isolation bracket 32, the isolation film component 33 will gradually leave the isolation channel 35 of the isolation bracket 32, and the isolation film component 33 will further release elastic energy until the isolation film component 33 completely leaves the isolation channel 35. As the isolation film assembly 33 gradually leaves the isolation channel 35, the scraper assembly 34 cleans the surface of the isolation film assembly 33 as the isolation film assembly 33 moves, and guides the cleaned dust and / or water to the dust exhaust port 12, so as to clean the dust and / or water on the electricity purchase card contaminated on the surface of the isolation film assembly 33, thereby avoiding contamination of the isolation channel 35, the card reader assembly 4, and the electricity purchase card, and ensuring the card insertion and electricity purchase environment.

[0034] Furthermore, the isolation film assembly 33 includes: a fixed roller 331, which is installed on one side of the top of the isolation bracket 32; a rotating roller 332, which is movably installed on the other side of the top of the isolation bracket 32; a winding roller 333, which is installed on one side of the isolation bracket 32 ​​close to the dust exhaust port 12, and the winding roller 333 is elastically rotatably connected to the isolation bracket 32; and an isolation film 334, one end of the isolation film 334 is connected to the fixed roller 331, and the other end of the isolation film 334 is connected to the winding roller 333.

[0035] In one embodiment of the present invention, the isolation film assembly 33, in its specific structure, comprises a fixed roller 331, a rotating roller 332 and a winding roller 333 to form an elastic mounting structure for the isolation film 334. Specifically, the fixed roller 331 and the rotating roller 332 are respectively mounted on both sides of the top of the isolation bracket 32, the winding roller 333 is mounted on one side of the isolation bracket 32, and one end of the isolation film 334 is connected to the fixed roller 331, and the other end of the isolation film 334 is connected to the winding roller 333, and the isolation film 334 between the fixed roller 331 and the winding roller 333 is laid on the rotating roller 332. When the electricity purchase card is inserted into the isolation channel 35, the isolation film 334 is released from the winding roller 333, and continuously moves from between the fixed roller 331 and the rotating roller 332 toward the isolation channel 35, and the winding roller 333 rotates to store elastic energy. When the electricity purchasing card is withdrawn, the winding roller 333 releases elastic energy and rotates in the opposite direction, rotating and winding the isolation film 334 onto the winding roller 333 .

[0036] like Figure 4 , Figure 7 and Figure 8 The winding roller 333 includes: a roller body 3331, both ends of which are respectively installed on one side of the isolation bracket 32; and a first torsion spring 3332, which is installed on the isolation bracket 32, and one end of the roller body 3331 is connected to the first torsion spring 3332, so that when the isolation membrane 334 drives the roller body 3331 to rotate along the first direction, the first torsion spring 3332 stores energy; when the isolation membrane 334 does not apply force to the roller body 3331, the first torsion spring 3332 rotates in the opposite direction to release energy.

[0037] In one embodiment of the present invention, when the winding roller 333 rotates to retract and release the isolation film 334, when the electricity purchasing card is inserted into the isolation channel 35, the isolation film 334 will be continuously released from the roller body 3331, and the first torsion spring 3332 will store energy; when the electricity purchasing card withdraws from the isolation channel 35, the first torsion spring 3332 will release energy, thereby driving the roller body 3331 to rotate, so that the isolation film 334 is wound around the roller body 3331, thereby achieving isolation through the isolation film 334 when the electricity purchasing card is inserted, and when the electricity purchasing card is withdrawn, the roller body 3331 is driven to rotate by the first torsion spring 3332, so that the isolation film 334 is automatically recovered on the roller body 3331.

[0038] like Fig. 9 As shown, the isolation membrane assembly 33 also includes: a clamp seat 335, which is slidably arranged at both ends of the isolation channel 35, and a socket 336 for inserting the isolation membrane 334 is provided on one side of the clamp seat 335, and the upper surface of the clamp seat 335 corresponds to the end surface of the power purchase card; and a guide rod 337, which is arranged at both ends of the isolation channel 35, and the upper and lower ends of the guide rod 337 are respectively connected to the isolation bracket 32, and the clamp seat 335 is slidably arranged on the guide rod 337; wherein, the sliding seals on both sides of the clamp seat 335 are arranged on the inner side wall of the isolation bracket 32.

[0039] In one embodiment of the present invention, during the process of releasing or rewinding the isolation film 334 of the isolation film assembly 33, the clamping seats 335 on both sides of the isolation film 334 can not only guide the isolation film 334 when it moves back and forth toward the isolation channel 35, but also seal both sides of the isolation film 334 in the isolation channel 35. In addition, when the power purchase card descends, the clamping seats 335 push the isolation film 334 to move together without contacting the surface of the isolation film 334, thereby improving the mobility of the power purchase card.

[0040] It should be added that Figure 7As shown, a limiting wire 337 is connected to the surface of the isolation membrane 334 along the winding direction of the isolation membrane 334, and a sliding groove corresponding to the limiting wire 337 is opened on the inner side wall of the socket 336 of the clamp seat 335, so that when the clamp seat 335 pulls the two ends of the isolation membrane 334 to move, the stability of the movement of the isolation membrane 334 can be improved.

[0041] like Figure 8 As shown, the scraper assembly 34 includes: an extension frame 341, which is mounted on one side of the isolation bracket 32; a rotating rod 342, which is rotatably mounted on the extension frame 341 and is mounted in the dust exhaust port 12; a scraper 343, which is mounted on the rotating rod 342, and the other side of the scraper 343 is laid on the surface of the isolation membrane 334 between the rotating roller 332 and the winding roller 333; and a second torsion spring 344, which is mounted on the extension frame 341 and one end of the rotating rod 342 is connected to the second torsion spring 344 so that the scraper 343 is elastically pressed on the surface of the isolation membrane 334.

[0042] In one embodiment of the present invention, when the isolation film 334 is released from the winding roller 333, the scraper assembly 34 does not clean the surface of the isolation film 334. When the isolation film 334 is recovered to the winding roller 333, the scraper 343 above the winding roller 333 is pressed against the surface of the isolation film 334 by the elastic force of the second torsion spring 344, and the surface of the isolation film 334 is cleaned. During the cleaning process, the cleaned dust and / or water will be further guided toward the side of the dust discharge port 12 through the scraper 343, and then discharged through the dust discharge port 12.

[0043] It should be added that Figure 4 and Figure 5 As shown, a limiting rod 345 is also connected between the extension frames 341, and the limiting rod 345 is also located above the scraper 343, so that when the scraper 343 rotates along the direction of energy release of the second torsion spring 344 due to the friction force of the isolation membrane 334, when it rotates to a certain angle, the position of the scraper 343 can be locked, and the surface of the isolation membrane 334 can be cleaned in this position.

[0044] Furthermore, sealing plates 346 are respectively installed on one side of the top of the extension frame 341 on both sides in the width direction of the isolation membrane 334, and the sealing plates 346 can be used to achieve local isolation when dust and / or water are transported toward the dust outlet 12. Furthermore, when the electric energy meter is installed vertically, the sealing plates 346 can be arranged obliquely along the horizontal direction of the electric energy meter installation, so that dust and / or water can slide along the obliquely arranged sealing plates 346 to the dust outlet 12.

[0045] like Figure 4As shown, the card reader assembly 4 includes: a card reader device 41, a card reading end 416 is provided on one side of the card reader device 41, and the card reading end 416 is inserted into the reading port 31; and a pushing unit 42, the pushing unit 42 is installed in the meter body 1, and the power output end of the pushing unit 42 is connected to the card reader device 41, so that after the electricity purchase card is in place, the card reading end 416 of the card reader device 41 is pushed to press against the surface of the electricity purchase card.

[0046] In one embodiment of the present invention, after the electricity purchase card is inserted into the isolation channel 35, the opening device 41 will identify and read the chip area corresponding to the electricity purchase card through the card reading end 416 through the card reading port 31. In the process of reading the card, the card reading end 416 of the card reader device 41 is pushed and pressed against the electricity purchase card by the pushing unit 42 to reduce the distance between the card and the electricity purchase card and improve the efficiency of identifying and reading the card. The pushing unit 42 can be a push rod motor.

[0047] like Figure 6 As shown, the card reader device 41 includes: a card reader 411; a moving seat 412, the moving seat 412 is located on one side of the card reader 411, and the power output end of the pushing unit 42 is connected to the moving seat 412; a driving motor 413, the driving motor 413 is installed on the moving seat 412, and an eccentric rod 414 is eccentrically connected to the power output end of the driving motor 413, and the other end of the eccentric rod 414 is connected to the card reader 411 to drive the card reading end 416 to eccentrically rotate in the reading port 31; and a lower bracket 415, the lower bracket 415 is guide-connected to one side of the bottom of the card reader 411 to guide the eccentric rotation of the card reader 411 and the movement toward the direction of the electricity purchasing card.

[0048] In one embodiment of the present invention, when the card reader device 41 is working, the eccentric rod 414 is driven to rotate by the driving motor 413, which is preferably a servo motor, so that the card reader 411 is guided by the lower bracket 415, so that the card reading end 416 of the card reader 411 rotates eccentrically in the reading port 31, so as to find and identify the chip position of the electricity purchase card at a faster speed and perform card reading processing.

[0049] Furthermore, if Figure 3As shown, the lower bracket 415 includes a bracket body 4151, a first slide groove 4152 opened on the bracket body 4151 along the width direction of the isolation membrane 334, a first slider 4153 slidably arranged in the first slide groove 4152, a first slide rod 4154 slidably inserted on the first slider 4153, and a second slider 5155 connected to the top of the first slide rod 4154. A second slide groove 4156 is opened at the bottom of the card reader 411, and the second slider 5155 is slidably arranged in the second slide groove 4156. Therefore, when the driving motor 413 drives the card reader 411 to rotate eccentrically, the card reader 411 can move back and forth in the first slide groove 4152 through the first slider 4153, move up and down under the guidance of the first slider 4153 through the first slide bar 4154, and move back and forth in the second slide groove 4156 through the second slider 5155 at the top of the first slide bar 4154, thereby maintaining the stability of the card reader 411 during eccentric rotation and realizing the movement guidance of the card reader 411 when it moves toward the side of the electricity purchasing card.

[0050] like Fig.11 As shown, the present invention also provides an electric energy meter box, including the aforementioned electric energy meter, and also includes: a box body 5, in which the electric energy meter is installed; a box door 6, which is rotatably connected to the opening of the box body 5; and a window 7; the window 7 is concave in shape, and the window 7 is installed in the middle of the box door 6, and an external card slot 71 corresponding to the card slot 11 is provided on the window 7.
