Description

Technical Field

[0001] This utility model relates to the field of battery switch technology, and in particular to a functional battery, battery box and gas system with built-in on / off switch. Background Technology

[0002] Most households are equipped with gas meters, which allow for a clear view of gas usage. The gas meter itself contains a solenoid valve, which controls the flow of gas from the source. If there is a gas balance, the solenoid valve will automatically open. If there is a gas balance outstanding, the gas company will close the solenoid valve, thereby shutting off the gas supply.

[0003] To prevent gas leaks, an alarm is usually installed near the gas meter. Once the gas leaks to a certain concentration, the alarm will sound, requiring manual closure of the mechanical valve after the gas meter to shut off the gas pipeline and prevent continuous leakage. However, the mechanical valve needs to be closed manually, and if no one is home, the gas will continue to leak, potentially causing an accident. If it is necessary to shut off the gas pipeline immediately upon alarm sounding, an electric control valve (solenoid valve) needs to be installed on the external gas pipeline. However, this requires additional modifications to the external gas pipeline and electrical circuit, which is time-consuming, labor-intensive, and increases costs. Utility Model Content

[0008] Furthermore, the conductive element is configured as an annular metal guide sleeve that opens toward the mounting shell. The annular metal guide sleeve is connected to the battery body near the side wall of the battery body. The end of the mounting shell near the battery body is inserted into the annular metal guide sleeve, and its outer side wall is provided with a stepped surface. The stepped surface abuts against the side wall of the annular metal guide sleeve away from the battery body. The annular metal guide sleeve is electrically connected to the main control board through a through hole provided on the peripheral side wall of the mounting shell; The positive terminal of the battery body is electrically connected to the main control board through through holes provided at the end of the annular metal guide sleeve near the positive terminal of the battery body and at the end of the mounting shell near the positive terminal of the battery body.

[0009] Furthermore, a first spring and a second spring are connected to the main control board; The first spring passes through the through hole provided at the end of the annular metal guide sleeve near the positive electrode of the battery body and the end of the mounting shell near the positive electrode of the battery body, and abuts against the positive electrode of the battery body; The second spring passes through the peripheral sidewall of the mounting housing and abuts against the inner sidewall of the conductive element.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-11 As shown, this embodiment of the utility model provides a functional battery with a built-in on / off switch, installed in a battery box 14. Specifically, it includes an outer insulating shell 1, a power supply battery 2, and a main control board 3. The power supply battery 2 and the main control board 3 are installed inside the outer insulating shell 1. An electronic switch 4 and a wireless receiving module are installed on the main control board 3. The positive and negative terminals of the power supply battery 2 are electrically connected to the main control board 3, forming an electrical connection path to power the wireless receiving module on the main control board 3 and the control coil in the electronic switch 4. Correspondingly, the outer insulating shell 1 has a negative terminal connector 6 and a positive terminal connector 5 at its two ends along its length. The negative terminal connector 6 and the positive terminal connector 5 are electrically connected to the two electrical connection terminals of the electronic switch 4. After the control coil in the electronic switch 4 is energized, the electronic switch 4 is in a normally closed state. Therefore, the entire battery can form an electrical connection path between the negative terminal connector 6, the electronic switch 4, and the positive terminal connector 5, allowing this functional battery to be placed in the battery box 14 and connected to other batteries to form a power supply path. The power module supplies power to external devices. However, if the external device needs to disconnect its internal current and stop operating under certain circumstances, it only needs to send a wireless signal to the wireless receiving module. The wireless receiving module then controls the current to break the circuit in the control coil of the electronic switch 4 via the main control board 3. This circuit breaking further controls the electronic switch 4 to open, creating an open circuit within the battery 16, thus disconnecting the power supply circuit from the battery box 14 to the device, causing the device to stop operating. The aforementioned functional battery 16, by internally housing the power supply battery 2, the main control board 3, and the electronic switch 4 and wireless receiving module on the main control board 3, allows it to function as a battery while also acting as a switch. If the device requires a switch, it can be installed in the battery box 14 like a regular battery 15, allowing external signals to control the current supply from the battery box 14 without additional circuit modifications, reducing modification costs and providing ease of use. It should be noted that the connection and control relationship between the electronic switch 4 and the wireless receiving module on the main control board 3 are existing technologies. It should also be noted that the battery box 14 on which the functional battery 16 is installed is not limited to ordinary battery boxes that are present on the device or stand alone. Here it is extended to the housing on which the slot that can be installed and participate in power supply can also be the battery box on which the aforementioned on / off switch can be installed.

[0023] Specifically, the main control board 3 and the power supply battery 2 are distributed along the length of the outer insulating shell 1, which wraps around the main control board 3 and the power supply battery 2. To protect the main control board 3 and the electronic switch 4 and ensure their stable installation within the outer insulating shell 1, a mounting shell 7, which is insulated from external conductors, is also provided inside the outer insulating shell 1. Here, the two ends of the main control board 3, distributed along the length of the outer insulating shell 1, abut against the two ends of the mounting shell 7, thus fixing the main control board 3 within the mounting shell 7. The outer insulating shell 1 has a first end 101 and a second end 102 distributed along its length, both of which are insulated from external conductors. The housing 1 has a through hole inside, wherein the two ends of the mounting housing 7 abut against the inner side wall of the first end 101 of the outer insulating housing 1 and the end side wall of the power supply battery 2 near the main control board 3, respectively. The end side wall of the power supply battery 2 away from the main control board 3 abuts against the negative electrode connector 6. The negative electrode connector 6 abuts against the inner side wall of the second end 102 of the outer insulating housing 1 and can be electrically connected to the external electrical connection terminals (positive and negative terminals of the battery and positive and negative terminals inside the battery box) through the through hole of the second end 102. The positive electrode connector 5 is partially located inside the mounting housing 7 and partially passes through the mounting housing 7 and the through hole of the first end 101 of the outer insulating housing 1 and is located outside the first end 101, thereby completing the electrical connection between the functional battery 16 and the external electrical appliance.

[0024] Specifically, the power supply battery 2 includes a battery body 21, an inner insulating shell 23, and a conductive component. The battery body 21 is arranged along the length of the outer insulating shell 1, with the positive terminal of the battery body 21 located close to the main control board 3. The conductive component is connected to the metal sidewall of the end of the battery body 21 near the main control board 3, thus the negative terminal of the battery body 21 is electrically connected to the conductive component through the metal shell of the battery body 21, making the conductive component act as the negative terminal of the battery body 21. Therefore, both the positive and negative terminals of the battery body 21 are located at the end of the battery body 21 near the main control board 3, and thus the positive and negative terminals of the battery body 21 are connected. It is much easier to connect to the main control board 3, and the electrical connection lines and connectors are shorter; the inner insulating sleeve opens towards the mounting shell 7 and is fitted around the outer periphery of the battery body 21 and the conductive parts, so as to cover the battery body 21 and the conductive parts inside and insulate them from the external negative terminal connector 6; specifically, the conductive parts are electrically connected to the main control board 3, so that the main control board 3 is electrically connected to the negative terminal of the battery body 21, and the positive terminal of the battery body 21 is electrically connected to the main control board 3, thereby enabling the battery body 21 to supply power to the main control board 3, so that the control coil of the electronic switch 4 and the wireless receiving module on it are energized.

[0025] Specifically, the conductive component is configured as an annular metal guide sleeve 22 with an opening facing the mounting shell 7. The annular metal guide sleeve 22 is made of conductive metal material. The side wall of the annular metal guide sleeve 22 near the battery body 21 is connected to the battery body 21. The end of the mounting shell 7 near the battery body 21 can be inserted into the annular metal guide sleeve 22. Its outer side wall is provided with a stepped surface 74. The stepped surface 74 abuts against the side wall of the conductive component away from the battery body 21, so that the mounting shell 7 is supported by the annular metal guide sleeve 22 and directly abuts against the entire power supply battery 2. Thus, the inner side wall of the first end 101 of the outer insulating shell 1, the mounting shell 7, the annular metal guide sleeve 22, the battery body 21, the inner insulating shell 23 and the outer insulating shell 1 abut against each other in sequence, making the internal structure of the entire functional battery 16 compact, smaller in size, and with each internal structure able to support each other, resulting in better strength. Furthermore, to improve the contact and support between the mounting shell 7 and the power supply battery 2, the end sidewall of the mounting shell 7 near the battery body 21 abuts against the inner sidewall of the annular metal guide sleeve 22 near the battery body 21. Moreover, for ease of installation, the outer insulating shell 1, inner insulating shell 23, mounting shell 7, and battery body 21 are all cylindrical. Therefore, the battery body 21 and the annular metal guide sleeve 22 are coaxially arranged, and the outer diameter of the end of the mounting shell 7 near the battery body 21 is consistent with the inner diameter of the annular metal guide sleeve 22, facilitating the centering of the mounting shell 7. The annular metal guide sleeve 22 can be made of materials such as aluminum, iron, or copper, specifically matching the outer shell material of the battery body 21.

[0026] Specifically, since the annular metal guide sleeve 22 is located on the outer periphery of the mounting shell 7, the conductive component is electrically connected to the main control board 3 through the through hole provided on the side wall of the mounting shell 7. The end of the annular metal guide sleeve 22 near the positive electrode of the battery body 21 and the end of the mounting shell 7 near the positive electrode of the battery body 21 are respectively provided with a first connection hole 221 and a second connection hole 73, and the positive electrode of the battery body 21 is electrically connected to the main control board 3 through the first connection hole 221 and the second connection hole 73.

[0027] Specifically, the main control board 3 is connected to a first spring 8 and a second spring 9. The first spring 8 passes through the first connection hole 221 and the second connection hole 73 and abuts against the positive terminal of the battery body 21, thereby realizing the electrical connection between the main control board 3 and the positive terminal of the battery body 21. The second spring 9 passes through the through hole on the side wall of the mounting shell 7 and abuts against the inner side wall of the conductive component, thereby realizing the connection between the negative terminal of the battery body 21 and the main control board 3. The positive and negative terminals of the battery body 21 are connected to the main control board 3 through the springs. On the one hand, the connection is convenient, and on the other hand, the elasticity of the springs can make the electrical connection between the two more stable.

[0028] Specifically, the main control board 3 is connected to a third spring 10 and a fourth spring 11. The positive electrode connector 5 is configured as a positive electrode plate 51. The end of the positive electrode plate 51 is confined within the mounting shell 7, and the positive electrode plate 51 protrudes outward from the mounting shell 7 to form a protrusion 52. The protrusion 52 passes through the side wall of the mounting shell 7 away from the battery body 21 and the side wall of the first end 101 of the outer insulating shell 1, and is located outside the outer insulating shell 1. The third spring 10 passes through the side wall of the end of the mounting shell 7 away from the battery body 21 and abuts against the inner side wall of the protrusion 52, thereby realizing the electrical connection between the positive electrode connector 5 and the electronic components on the main control board 3. Under the action of the third spring 10, the protrusion 52 can approach the main control board 3 under the action of external force, which facilitates the installation of the positive electrode connector 62 of the functional battery 16. The negative electrode connector 6 includes a negative electrode plate 61 and a connecting piece 62. The negative electrode plate 61 is located between the battery body 21 and the outer insulating shell 1, and is used to connect to the outside through the through hole of the second end 102 of the outer insulating shell 1. The connecting piece 62 is connected to the outer edge of the negative electrode plate 61 and extends along the length of the outer insulating shell 1 to the mounting shell 7. The negative electrode plate 61 is located between the outer insulating shell 1 and the inner insulating shell 23. The fourth spring 11 passes through the peripheral side wall of the mounting shell 7 and abuts against the fourth spring 11, thereby realizing the electrical connection between the negative electrode connector 6 and the electronic switch 4 on the main control board 3. The negative electrode connector 6 and the positive electrode connector 5 are both connected to the main control board 3 through springs. On the one hand, the connection is convenient, and on the other hand, the elastic force of the spring can make the electrical connection between the two more stable.

[0029] It is important to know that the ends of the first spring 8, the second spring 9, the third spring 10, and the fourth spring 11 are respectively inserted into the sockets provided on the main control board 3 to achieve electrical connection between the springs and the main control board 3, and the installation is convenient. Furthermore, the third spring 10 and the first spring 8 are respectively located at both ends of the main control board 3 along the length of the outer insulating shell 1, so that the axial force on the main control board 3 is balanced, and the connection between the first spring 8 and the third spring 10 and the positive terminal of the battery body 21 and the positive terminal connector 5 is more stable.

[0030] Specifically, the mounting shell 7 can be a plastic shell, specifically including a first shell 71 and a second shell 72. The first shell 71 and the second shell 72 are detachably connected. Both the first shell 71 and the second shell 72 are semi-cylindrical structures. In this embodiment, the ends of the first shell 71 and the second shell 72 that come into contact are respectively provided with a first stepped surface and a second stepped surface. The first stepped surface and the second stepped surface abut against each other, thereby facilitating the installation of the first shell 71 and the second shell 72 into a whole. The first stepped surface 74 and the second stepped surface 74 can be glued together to fix the first shell 71 and the second shell 72 together to form the mounting shell 7. Of course, the upper and lower ends of the mounting shell 7 are provided with through holes for the first spring 8 and the third spring 10 to pass through, respectively. In another embodiment, the first shell 71 and the second shell 72 are snap-fitted together, that is, the first shell 71 is provided with a protrusion, and the second shell 72 is provided with a corresponding groove. The connection between the first shell 71 and the second shell 72 is achieved by the snap-fitting of the protrusion and the groove.

[0031] Specifically, a limiting plate 75 is provided on the peripheral wall of the end of the mounting shell 7 formed by the first shell 71 and the second shell 72 away from the battery body 21. The limiting plate 75 is spaced apart from the inner wall of the end of the mounting shell 7 away from the battery body 21, thereby forming a limiting space. The positive electrode 51 is inserted into the limiting space, so that the positive electrode 51 is limited to the mounting shell 7. The protrusion 52 protrudes out of the outer insulating shell 1 and is electrically connected to the outside.

[0032] Specifically, this functional battery 16 also includes a negative electrode insulating sheet 12 and a positive electrode insulating sheet 13. The negative electrode insulating sheet 12 is disposed between the inner insulating shell 23 and the battery body 21, so the inner insulating shell 23 can adopt an existing bottom-opening insulating sleeve. The positive electrode insulating sheet 13 is pressed between the inner side wall of the first end 101 of the outer insulating shell 1 and the outer side wall of the mounting shell 7, ensuring stable conductivity between the positive electrode connector 5 and the negative electrode connector 6. Moreover, the negative electrode insulating sheet 12 and the positive electrode insulating sheet 13 are set as rubber pads. The positive electrode insulating sheet 13 facilitates the buffered connection between the first end 101 of the outer insulating shell 1 and the mounting shell 7, and the negative electrode insulating sheet 12 facilitates the buffered connection between the negative electrode connector 6 and the inner insulating shell 23. It should also be noted that the outer insulating shell 1 can be an insulating sleeve.

[0033] This utility model discloses a battery box, including a battery box body. The battery box body is provided with a common battery 15 and the aforementioned functional battery 16. The common battery 15 and the functional battery 16 are installed in corresponding installation positions within the battery box body. Their conductive sheets abut against each other and are electrically connected. Thus, the entire battery box 14 has both power supply function and switching function. When installed in a device, it can switch the internal circuit of the device on and off by cooperating with an external detection device when powering the device.

[0034] The existing gas meter 17 has a solenoid valve inside to manage the on / off state of the entire gas pipeline. During installation, a mechanical main valve is installed on the gas pipeline below the gas meter 17. Users can only manually operate this mechanical main valve to shut off the gas pipeline. However, in the event of a gas leak and no one is home, the mechanical main valve will remain open, potentially leading to an accident. To automatically control the on / off state of the gas pipeline outside the gas meter 17, an electronic valve (such as a solenoid valve) needs to be installed outside the gas pipeline and used in conjunction with an alarm. This requires modifying the circuitry and piping, which is time-consuming and labor-intensive. Furthermore, the solenoid valve itself is not inexpensive. Based on the current state of existing household gas meters 3 and gas pipelines, this utility model embodiment also discloses a gas system, specifically including a gas meter 17 and an alarm module 18 located outside the gas meter 17. The alarm module 18 can be an alarm, and the gas meter 17 has the aforementioned battery. Battery box 14 supplies power to gas meter 17, energizing the solenoid valve inside and thus making gas meter 17 work. Alarm module 18 is wirelessly connected to wireless receiver module in functional battery 16. When alarm module 18 detects a gas leak to a certain extent, it transmits this signal to wireless receiver module, which then de-energizes the control coil of electronic switch 4 via main control board 3. Electronic switch 4 then disconnects, battery box 14 stops supplying power, thus disconnecting the solenoid valve inside gas meter 17. Gas meter 17 then stops working, closing the gas pipeline and preventing further gas leakage, thus avoiding safety accidents caused by excessive gas leakage. After the alarm signal or fault signal is cleared, alarm module 18 resets. Wireless receiver module receives a signal indicating normal operation of alarm module 18, energizing the control coil of electronic switch 4, closing electronic switch 4, resuming power supply from battery box 14, opening the solenoid valve, and restarting gas meter 17. It's important to know that no professional is needed to modify the circuitry and gas lines (i.e., add a solenoid valve to the external gas line), nor is it necessary to operate the mechanical main valve on the gas line. Simply replacing the battery in the battery box 14 inside the gas meter 17 can perfectly solve the problem of current alarms on the market that only sound an alarm but cannot shut off the gas.

[0035] It should be noted that the gas meter 17 mentioned above can be used in households where the circuits and pipes have not been modified (i.e., a solenoid valve is added to the gas pipeline), or in households where the circuits and pipes have been modified. This is because there is a possibility of leakage in the pipeline between the added solenoid valve and the solenoid valve inside the gas meter 17, and the solenoid valve of the gas meter 17 is the main valve of the gas pipeline, which plays the role of main on / off control.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
