[0027] See also Figure 1 and 2 The present invention provides an electric energy meter, comprising: a meter body 1, which is provided with a card insertion port 11 and a dust exhaust port 12; a guide component 2, which is mounted on the meter body 1 and is adjacent to the card insertion port 11, so as to guide the electricity purchase card inserted into the card insertion port 11 toward the inside of the meter body 1; an isolation component 3, which has a reading port 31 on one side and is mounted in the meter body 1, so as to isolate the electricity purchase card when the guide component 2 is input into the isolation component 3, and to perform self-cleaning when the electricity 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 mounted in the meter body 1 and movably disposed in the reading port 31, so as to perform mobile identification and card reading on the electricity purchase card inserted into the isolation component 3.
[0028] From the foregoing, it is readily apparent that in the electricity meter provided by the present invention, the electricity purchase card is inserted into the meter through the card insertion port 11 on the meter body 1. When the electricity purchase card enters the transmission assembly 2 through the card insertion port 11, the transmission assembly 2 senses the card and, driven by the transmission assembly 2, further moves the card toward the isolation assembly 3. Specifically, upon contact with the electricity purchase card, the transmission assembly 2 can detect pressure signals from the card's contact, for example, through a pressure sensor, thereby driving the card toward the isolation assembly 3. As the electricity purchase card moves further, it reaches the card reading area of the card reader assembly 4 under the isolation effect of the isolation assembly 3. Once the electricity purchase card reaches the card reading area of the card reader assembly 4, the card reader assembly 4 automatically moves back and forth around the electricity purchase card chip, searching for the card chip's location, thereby facilitating rapid detection and card reading. After the electricity purchase card is identified and electricity is purchased, the transmission component 2 further transmits the electricity purchase card in the reverse direction, thereby removing the card. Simultaneously, the isolation component 3 automatically cleans its internal surface that contacts the electricity purchase card and discharges dust from the dust outlet 12. This isolation method protects the card insertion space and the card reader assembly 4's card reader identification area, preventing dust, water, and other debris from the electricity purchase card from entering the card insertion space and the card reader assembly 4's card reader identification area, thereby affecting the further use of the card reader assembly 4. For example, this could cause moisture inside the electricity meter due to water contamination. Furthermore, this could affect the further use of electricity purchases. For example, if contaminants such as particles are present in the card insertion space, the surface of the electricity purchase card could be scratched or 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, the card reader component 4 performs mobile identification and card reading when reading the electricity purchase card, which can effectively enhance the reading ability of the card reader component 4 for the electricity purchase card, 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 the limited card insertion space, thereby improving the electricity purchasing efficiency of the electricity purchase card.
[0029] like Figure 4 As shown, the transmission assembly 2 includes: a transmission base 21, on which a transmission channel 22 is provided; and a transmission wheel 23, which is provided in the transmission channel 22 to contact the two sides of the inserted power purchase card and drive the power purchase card to move back and forth along the transmission channel 22; wherein the transmission wheel 23 is an elastic wheel.
[0030] In one embodiment of the present invention, when the electricity purchase card enters the guide assembly 2 through the card insertion port 11, it contacts the guide rollers 23 within the guide channel 22. This contact causes the guide rollers 23 to rotate, driving the electricity purchase card through the guide channel 22 to the isolation assembly 3, where it is identified and read by the card reader assembly 4 on one side of the isolation assembly 3. In this embodiment, the guide base 21 is further provided with a synchronous gearbox and servo motor to drive the guide rollers 23. The power output of the synchronous gearbox is connected to each guide roller 23, while the power output of the servo motor is connected to the power input of the synchronous gearbox. This allows the servo motor to drive the guide rollers 23, driven by the synchronous gearbox, to rotate, thereby moving the electricity purchase card along with it.
[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, driving the guide wheel 23 driven by the synchronous gearbox to rotate, thereby driving 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 electricity purchasing card; an isolation membrane component 33, which is elastically mounted on both sides of the top of the isolation bracket 32, so that the conveying component 2 carries the electricity purchasing card and pushes the isolation membrane component 33 toward the isolation channel 35 for isolation, and when the electricity 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 mounted 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 power purchase card is driven by the transmission assembly 2 and reaches the isolation assembly 3, it will correspondingly reach the top of the isolation bracket 32, corresponding to the isolation passage 35. As the power purchase card continues to move, it pushes the isolation membrane assembly 33 toward the isolation passage 35 until it reaches the card reader assembly 4's card recognition area. Furthermore, when the power purchase card reaches the card reader assembly 4's card recognition area, the isolation membrane assembly 33 is in an elastic energy storage state. Subsequently, when the power purchase is successful and the power purchase card leaves the isolation passage 35 of the isolation bracket 32, the isolation membrane assembly 33 gradually leaves the isolation passage 35 of the isolation bracket 32, further releasing elastic energy until the isolation membrane assembly 33 completely leaves the isolation passage 35. As the isolation membrane assembly 33 gradually leaves the isolation channel 35, the scraper assembly 34 cleans the surface of the isolation membrane assembly 33 as the isolation membrane assembly 33 moves, and guides the cleaned dust and / or water to the dust exhaust port 12 to clean the dust and / or water on the electricity purchase card contaminated on the surface of the isolation membrane assembly 33, thereby avoiding contamination of the isolation channel 35, the card reader assembly 4, and the electricity purchase card, and ensuring a safe environment for inserting and purchasing electricity with the electricity purchase card.
[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 near 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 comprises a fixed roller 331, a rotating roller 332, and a take-up roller 333, which form an elastic mounting structure for the isolation film 334. Specifically, the fixed roller 331 and the rotating roller 332 are mounted on either side of the top of the isolation bracket 32, and the take-up roller 333 is mounted on one side of the isolation bracket 32. One end of the isolation film 334 is connected to the fixed roller 331, and the other end is connected to the take-up roller 333. The isolation film 334 between the fixed roller 331 and the take-up roller 333 is then placed on the rotating roller 332. When the electricity purchase card is inserted into the isolation channel 35, the isolation film 334 is unwound from the take-up roller 333 and continuously moves from between the fixed roller 331 and the rotating roller 332 toward the isolation channel 35. Simultaneously, the take-up 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 the roller body 3331 are respectively installed on one side of the isolation bracket 32; and a first torsion spring 3332, the first torsion spring 3332 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 extend 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 exits 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 exited, 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 Figure 9 As shown, the isolation membrane assembly 33 also includes: a clamping 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 clamping seat 335, and the upper surface of the clamping seat 335 corresponds to the end surface of the electricity 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 clamping seat 335 is slidably arranged on the guide rod 337; wherein, the sliding seals on both sides of the clamping seat 335 are arranged on the inner side wall of the isolation bracket 32.
[0039] In one embodiment of the present invention, during the unwinding or rewinding process, the isolation film 334 of the isolation film assembly 33 is guided back and forth within the isolation passage 35 by clamping seats 335 on both sides of the isolation film 334. This not only ensures that both sides of the isolation film 334 are sealed within the isolation passage 35, but also that the isolation film 334 is pushed along by the clamping seats 335 when the electricity purchasing card is lowered, without contacting the surface of the isolation film 334, thereby improving the mobility of the electricity purchasing 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 the rotating rod 342 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 placed 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 unwound from the take-up roller 333, the scraper assembly 34 does not clean the surface of the isolation film 334. When the isolation film 334 is retracted onto the take-up roller 333, the scraper 343 above the take-up roller 333, under the elastic force of the second torsion spring 344, is pressed against the surface of the isolation film 334 and cleans the surface of the isolation film 334. During the cleaning process, the removed dust and / or water is further guided by the scraper 343 toward the dust outlet 12, where it is discharged through the dust outlet 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 mounted on one side of the top of the extension frame 341 on both sides in the width direction of the isolation membrane 334. These sealing plates 346 can achieve partial isolation of dust and / or water as they are transported toward the dust outlet 12. Furthermore, when the energy meter is mounted vertically, the sealing plates 346 can be arranged at an angle along the horizontal direction of the energy meter installation, thereby facilitating the sliding of dust and / or water along the inclined 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 uses the card reader end 416 to read the chip area corresponding to the electricity purchase card through the card reading port 31. Furthermore, during the card reading process, the card reader end 416 of the card reader device 41 is pressed against the electricity purchase card by a pressing unit 42, thereby reducing the distance between the card and the card and improving the recognition and reading efficiency. The pressing unit 42 may be a push rod motor.
[0047] like Figure 6 As shown, the card reader device 41 includes: a card reader 411; a movable base 412, the movable base 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 movable base 412; a driving motor 413, the driving motor 413 is installed on the movable base 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 rotate eccentrically in the reading port 31; and a lower bracket 415, the lower bracket 415 is guide-connected to the bottom side of the card reader 411 to guide the eccentric rotation of the card reader 411 and the movement toward the electricity purchase 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, thereby searching and identifying the chip position of the electricity purchase card at a faster speed.
[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 slidingly arranged in the first slide groove 4152, a first slide rod 4154 slidingly 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. Thus, when the drive 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 rod 4154, and move back and forth in the second slide groove 4156 through the second slider 5155 at the top of the first slide rod 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 purchase card.
[0050] like Figure 11 As shown, the present invention also provides an electric energy meter box, including the aforementioned electric energy meter, and also includes: a box shell 5, in which the electric energy meter is installed; a box door 6, which is rotatably connected to the opening of the box shell 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.
[0051] In one embodiment of the present invention, in the electric energy meter box obtained by the present invention, when the aforementioned electric energy meter is in use, in order to facilitate the realization of the electricity purchasing efficiency of the electricity purchasing card, the window 7 of the box door 6 can be designed to be concave, so that the electricity purchasing card can be directly inserted into the external card slot 71 of the window 7 close to the card insertion port 11 without opening the box door 6 of the box shell 5, and then directly inserted into the electric energy meter through the card insertion port 11, so that the card reader device 41 can quickly identify and read the electricity purchasing card.
[0052] In summary, the present invention, through the design of the guide assembly 2 and isolation assembly 3 within the card insertion port 11 of the electricity meter, facilitates the automatic guidance of the electricity purchase card by the guide assembly 2 to the isolation assembly 3 when the electricity purchase card is inserted. Furthermore, when guided to the isolation assembly 3, the isolation assembly 3 can also isolate the electricity purchase card and deliver it to the corresponding card reading area of the card reader assembly 4 for identification and reading. During card reading, the card reader assembly 4 automatically moves and adjusts the position of the card reading identification area to ensure automatic search and identification of the chip area on the electricity purchase card, thereby improving the efficiency of card reading. Furthermore, during card reading, the card reader assembly 4 automatically moves toward the side of the electricity purchase card to maintain a distance from the card, improving recognition efficiency and avoiding problems such as damage to the electricity purchase card caused by manual adjustment of the card when the card is at the identification distance from the card reader. Furthermore, when the electricity purchase card is removed, the isolation component 3 automatically cleans and discharges dust particles and / or water carried by the electricity purchase card, thereby reducing contamination of the card insertion space of the electricity meter. This also prevents the electricity purchase card from being scratched or contaminated by dust particles and / or water in the card insertion space the next time the electricity purchase card is inserted. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
