Description

Technical Field

[0001] This invention relates to the field of home appliances, and more particularly to a battery modification structure. Background Technology

[0002] Traditional battery conversion kits allow you to insert AAA batteries. The kit is the size of a AAA battery, so you can use AAA batteries as an emergency solution when you run out of AAA batteries.

[0003] The modification kit has a simple structure and only changes the size of the battery adapter; it does not have any control function. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this invention is to provide a battery modification structure that can solve the emergency use when the original system battery is insufficient without changing other structures, and can also facilitate the control of power outages.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] The battery modification structure includes a housing for installing a replacement battery and a controller; the housing is provided with a positive conductive part and a negative conductive part that match the replacement battery, and the replacement battery and the controller are connected in series between the positive conductive part and the negative conductive part, and the controller can cut off the conduction between the replacement battery and the positive conductive part or the negative conductive part.

[0007] By adopting the above technical solution, the casing of the modified battery structure is connected in series with other power sources of the appliance, such as AA batteries. The controller can switch the positive conductive part, the negative conductive part, and the connection or disconnection between the batteries, thereby disconnecting the power supply part of the appliance and achieving the effect of power outage to stop the appliance from operating.

[0008] Existing gas meters use AA batteries as DC power sources and automatically shut off the gas switch when the power is off. By connecting the battery housing in series with the AA battery in the gas meter, the power to the gas meter can be directly controlled to shut off the main gas switch.

[0009] As an improvement, the controller is a control chip, and the positive terminal of the battery is electrically connected to the positive conductive part through the control chip, or the negative terminal of the battery is electrically connected to the negative conductive part through the control chip.

[0010] By adopting the above technical solution, the control chip, as a controller, can be set in parallel with the replacement battery on the side of the casing and connected in series with the battery, saving internal space in the battery modification structure.

[0011] As an improvement, the control chip is electrically connected to the battery, and the control chip is powered by a replacement battery.

[0012] As an improvement, the housing has a partition between the replacement battery and the positive / negative conductive part, and the control chip is disposed on the side of the partition; the battery is electrically connected to the control chip through a chip conductive element, and the control chip is electrically connected to the positive / negative conductive part.

[0013] By adopting the above technical solution, the two ends of the casing are provided with the same positive and negative conductive parts as the replacement battery. Since the separator of the replacement battery is in an open circuit state with the positive / negative conductive parts, it needs to be connected in series through a control chip.

[0014] As an improvement, the housing matches the replacement battery slot of the gas meter, and the positive and negative conductive parts are respectively located at both ends of the housing. Specifically, the length and width dimensions of the housing, as well as the positions of the positive and negative conductive parts, are the same as those of a standard AA replacement battery. The replacement battery inside the housing is smaller than a standard AA replacement battery and can be a AAA replacement battery or other small-sized replacement batteries.

[0015] By adopting the above technical solution, the battery modification structure can be directly installed to replace the AA replacement battery in the gas meter, thus achieving the simple and quick modification of the gas meter to cut off power and gas supply.

[0016] As an improvement, the control chip includes a signal receiving element, a power-off element, and a power-off switch, wherein the signal receiving element and the power-off element are signal-connected, and the power-off element and the power-off switch are signal-connected.

[0017] Specifically, the modified battery structure and the first power source installed inside the casing form a control module; the gas meter, the control module, and the power-off switch of the control module are connected in series with the second power source.

[0018] When the power-off switch is connected, the first power source is connected in parallel with the signal receiving element and the power-off element in the battery modification structure.

[0019] When the power-off switch is disconnected, the first power source is connected in series with the signal receiving element and the power-off element in the battery modification structure.

[0020] More preferably, the control chip further includes a boost module, which is connected in series with the signal receiving element and the power-off element.

[0021] By adopting the above technical solution, the control chip can control the replacement battery to power off or connect by receiving external signals. It can be a wired signal connection or a wireless signal connection. For ease of installation, a wireless signal connection is adopted here.

[0022] As an improvement, a backup power supply box is also included, which includes a second housing; the second housing is capable of housing a replacement battery; the backup power supply box is electrically connected to the control chip.

[0023] By adopting the above technical solution, the backup power box serves as a backup power source for the control chip, thereby improving the battery modification structure's range.

[0024] As an improvement, the second housing is provided with a positive active electrode and a negative active electrode that are electrically connected to the positive and negative terminals of the replacement battery inside the second housing, respectively. The housing is provided with conductive patches that match the positive and negative active electrodes. The conductive patches are also provided with magnetic components that can attract the positive and negative active electrodes. The conductive patches are electrically connected to the control chip.

[0025] By adopting the above technical solution, the magnetic component attracts the positive and negative active electrodes to the conductive patch, ensuring good contact between the conductive patch and the positive and negative active electrodes. The positive and negative active electrodes can also be manually adjusted to move away from the conductive patch, facilitating disassembly and installation.

[0026] As an improvement, the second housing includes a main body and a cover plate. The main body has a mounting compartment that matches the replacement battery and has an opening at the top. The cover plate is disposed below the main body and forms a sliding channel with the main body.

[0027] The sliding channel has a positive conductive sheet that is electrically connected to the positive electrode of the replacement battery and a negative conductive sheet that is electrically connected to the negative electrode on both sides.

[0028] A sliding conductive element is provided in the sliding channel. The sliding conductive element includes a positive conductive plate electrically connected to the positive electrode conductive sheet, a positive limiting element electrically connected to the positive conductive plate, and a positive movable electrode disposed on the positive limiting element and capable of moving to both sides of the second housing.

[0029] The sliding conductive component also includes a negative conductive plate electrically connected to the negative conductive sheet, a negative limiting component electrically connected to the negative conductive plate, and a negative movable electrode disposed on the negative limiting component and capable of moving to both sides of the second housing.

[0030] By adopting the above technical solution, the positive and negative active electrodes are disposed on the sliding conductive component and can change their positions on the side of the backup power box as the sliding conductive component moves, facilitating reliable electrical connection when the conductive patch on the housing is in different positions. The positive and negative active electrodes are respectively connected to the positive and negative terminals of the replacement battery through a limiting component, a conductive plate, and a conductive sheet, so that a reliable electrical connection can be maintained between the active electrodes and the replacement battery no matter where the sliding conductive component slides to.

[0031] A gas leak prevention device includes a monitoring component and a battery modification structure as described in any of the preceding claims, wherein the monitoring component is signal-connected to the battery modification structure.

[0032] By adopting the above technical solution, the monitoring component can send a signal to the battery modification structure when a gas leak is detected, control the battery modification structure to disconnect the circuit, thereby cutting off the power supply to the gas meter and automatically cutting off the gas supply from the gas inlet, ensuring that the gas leak point inside the house cannot continue to leak gas.

[0033] As an improvement, the monitoring component is equipped with a signal transmitter, the power-off group is equipped with a signal receiving element, and the signal transmitter and the signal receiving element are wirelessly connected.

[0034] As an improvement, the replacement battery is a No. 7 battery, and the size and shape of the casing (1) match that of a No. 5 battery.

[0035] By adopting the above technical solution, a wireless signal connection is established between the monitoring component and the battery modification structure, eliminating the need to lay physical signal cables between them, thus increasing installation flexibility and reducing the cost of installing signal cables.

[0036] As an improvement, the monitoring component also includes a control terminal, which is wirelessly connected to the signal receiving element. Specifically, the control terminal can be a remote control, mobile phone software, or other forms.

[0037] This allows for remote control of the battery modification structure to be powered on or off via a control terminal, thereby enabling remote control of the gas supply inside the house to be cut off or allowed, increasing the degree of freedom of use.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] This battery modification structure can be applied to various work fields. Replacing the original system battery with the battery modification structure of this invention does not require any other structural changes. It not only solves the emergency use problem when the original system battery is insufficient, but also facilitates the control system's power outage. By connecting the casing of the battery modification structure in series with other power sources of electrical appliances, such as AA batteries, a controller can switch the positive and negative conductive parts, or the connection or disconnection between the batteries, thereby disconnecting the power supply to the electrical appliance and stopping its operation. Existing gas meters use AA batteries as DC power sources, and automatically shut off the gas switch when the power is cut off. By connecting the casing of the battery modification structure in series with the AA batteries of the gas meter, the power to the gas meter can be directly controlled, thereby shutting off the main gas switch.

[0059] Implementation Case 1:

[0060] As attached Figure 1-6 As shown, a battery modification structure includes a housing 1 and a controller and a replacement battery 2 disposed on the housing 1; the housing 1 is provided with a positive conductive part 3 and a negative conductive part 4 that match the replacement battery 2, and the replacement battery 2 and the controller are connected in series between the positive conductive part 3 and the negative conductive part 4.

[0061] By connecting the battery modification structure housing 1 in series with other power sources of the appliance (such as AA replacement battery 2), the controller can switch the connection or disconnection between the positive conductive part 3, the negative conductive part 4, and the replacement battery 2, thereby disconnecting the power supply of the appliance and stopping its operation. The existing gas meter uses AA replacement battery 2 as a DC power source, and automatically shuts off the gas switch when the power is cut off. By connecting the battery modification structure housing 1 in series with the AA replacement battery 2 of the gas meter, the power to the gas meter can be directly controlled to shut off the main gas switch.

[0062] The controller is a control chip 5. The positive terminal of the replacement battery 2 is electrically connected to the positive conductive part 3 through the control chip 5, or the negative terminal of the replacement battery 2 is electrically connected to the negative conductive part 4 through the control chip 5.

[0063] The control chip 5, acting as a controller, can be arranged in parallel with the replacement battery 2 on the side of the housing 1 and connected in series with the replacement battery 2, saving internal space in the battery modification structure.

[0064] The housing 1 has a partition 6 between the replacement battery 2 and the positive conductive part 3 / negative conductive part 4; the replacement battery 2 and the positive conductive part 3 / negative conductive part 4 are electrically connected by the control chip 5 bypassing the partition 6.

[0065] The housing 1 has a positive conductive part 3 and a negative conductive part 4 at both ends, which are the same as those of the replacement battery 2. Since the separator 6 of the replacement battery 2 is in an open circuit state with the positive conductive part 3 / negative conductive part 4, it needs to be connected in series with the control chip 5 through the chip conductive part 24.

[0066] The housing 1 is matched with the replacement battery 2 slot of the gas meter, and the positive conductive part 3 and the negative conductive part 4 are respectively disposed at both ends of the housing 1. Specifically, the length and width dimensions of the housing 1 and the positions of the positive conductive part 3 and the negative conductive part 4 are the same as those of a typical AA replacement battery 2. The replacement battery 2 inside the housing 1 is smaller than a typical AA replacement battery 2, and can be a AAA replacement battery 2 or other small-sized replacement batteries 2.

[0067] It can directly replace the No. 5 replacement battery 2 in the gas meter with the battery modification structure, thus simply and quickly realizing the modification of the gas meter to cut off power and gas.

[0068] The control chip 5 is provided with a signal receiving element 7; one end of the signal receiving element 7 is connected to the control chip 5, and the other end protrudes from the housing 1.

[0069] The control chip 5 can control the replacement battery 2 to disconnect or connect by receiving external signals.

[0070] It also includes a backup power box, which includes a second housing 8 and a replacement battery 2 disposed within the second housing 8; the backup power box is connected in series with the control chip 5 and in parallel with the replacement battery 2 within the housing 1.

[0071] The replacement battery 2 inside the casing 1 is connected in parallel with the backup power box to serve as a backup power source for the control chip 5, thereby improving the battery modification structure's range.

[0072] The second housing 8 is provided with a positive active electrode 10 and a negative active electrode 11 that are electrically connected to the positive and negative terminals of the replacement battery 2 inside the second housing 8, respectively. The housing 1 is provided with a conductive patch 9 that matches the positive active electrode 10 and the negative active electrode 11. The conductive patch 9 is also provided with a magnetic element 12 that can attract the positive active electrode 10 and the negative active electrode 11. The conductive patch 9 is electrically connected to the control chip 5.

[0073] The magnetic component 12 attracts the positive movable electrode 10 and the negative movable electrode 11 to the conductive patch 9, ensuring good contact between the conductive patch 9 and the positive and negative movable electrodes 10 and 11. The positive and negative movable electrodes 10 and 11 can also be manually adjusted away from the conductive patch 9 for easy disassembly and installation.

[0074] The second housing includes a main body 13 and a cover plate 14. The main body 13 has a mounting compartment that matches the battery and an opening at the top. The cover plate 14 is located below the main body and surrounds the main body 13 to form a sliding channel.

[0075] The sliding channel is provided with a positive conductive sheet 15 electrically connected to the positive electrode of the battery and a negative conductive sheet 16 electrically connected to the negative electrode on both sides.

[0076] A sliding conductive element is provided in the sliding channel. The sliding conductive element includes a positive conductive plate 17 electrically connected to the positive electrode conductive sheet 15, a positive limiting element 19 electrically connected to the positive conductive plate 17, and a positive movable electrode 10 disposed on the positive limiting element 19 and capable of moving to both sides of the second housing 8.

[0077] The sliding conductive component also includes a negative conductive plate 18 electrically connected to the negative conductive sheet 16, a negative limiting component 20 electrically connected to the negative conductive plate 18, and a negative active electrode 11 disposed on the negative limiting component 20 and capable of moving to both sides of the second housing 8.

[0078] The positive movable electrode 10 and the negative movable electrode 11 are disposed on the sliding conductive member and can change their positions on the side of the backup power box as the sliding conductive member moves, so as to maintain a reliable electrical connection when the conductive patch 9 of the housing 1 is in different positions. The positive movable electrode 10 and the negative movable electrode 11 are respectively connected to the positive and negative terminals of the battery through a limiting member, a conductive plate, and a conductive sheet, so that the movable electrode and the battery can be reliably electrically connected no matter where the sliding conductive member slides.

[0079] A gas leak prevention device includes a monitoring component and a battery modification structure as described above, wherein the monitoring component is signal-connected to the battery modification structure.

[0080] When a gas leak is detected, the monitoring component sends a signal to the battery modification structure to cut off the circuit, thereby cutting off the power to the gas meter and automatically shutting off the gas supply from the gas inlet point, ensuring that the gas leak point inside the house can no longer leak gas.

[0081] The monitoring component is equipped with a signal transmitter, and the power-off group is equipped with a signal receiving element 7. The signal transmitter and the signal receiving element 7 are wirelessly connected.

[0082] The monitoring components and the battery modification structure are connected wirelessly, eliminating the need for physical signal cables between them, which increases installation flexibility and reduces the cost of installing signal cables.

[0083] The monitoring component also includes a control terminal, which is wirelessly connected to the signal receiving element 7. Specifically, the control terminal can be a remote control, mobile phone software, or other forms.

[0084] This allows for remote control of the battery modification structure to be powered on or off via a control terminal, thereby enabling remote control of the gas supply inside the house to be cut off or allowed, increasing the degree of freedom of use.

[0085] The working principle of this invention is as follows:

[0086] This battery modification structure can be applied to various work fields. By replacing the system battery with the battery modification structure of this invention, the power supply to the system can be easily controlled without changing other structures. For example, this invention can quickly modify the original AAA battery to the size of a AA battery, and through the control chip, the power supply of the replacement battery can be cut off as needed to achieve the effect of system power-off. For example, a high-temperature detection device uses three AA batteries. When only two AA batteries and one AAA battery are available, this battery modification structure can be used to ensure the normal operation of the detection device. When the temperature exceeds a predetermined value, the control chip receives the signal and cuts off the power to the detection device. After the power is cut off, the system detects a fault in the detection device and can issue a warning signal.

[0087] The monitoring component is connected to the battery modification structure via a signal. The monitoring component is equipped with a gas sensor and a signal transmitter. When the gas sensor of the monitoring component detects a gas leak, it sends a command through the signal transmitter to cut off the power to the battery modification structure.

[0088] The battery modification structure has the same external dimensions as the battery used in the gas meter (usually an AA battery). One or more AA batteries in the gas meter are replaced with this battery modification structure, meaning the battery modification structure, the AA batteries, and the gas meter are connected in series. When the signal receiving element 7 of the battery modification structure receives a command from the signal transmitter, the control chip 5 is disconnected. Since the two ends of the control chip 5 are connected in series with the replacement battery 2 and the positive conductive part 3 / negative conductive part 4 within the battery modification structure, the disconnection of the control chip 5 causes the battery modification structure to disconnect, which in turn disconnects the power supply line to the gas meter. In the power-off state, the gas meter automatically closes the gas valve, preventing gas from entering the household through the gas meter, and all gas leak points within the household will no longer leak gas.

[0089] The positive active electrode 10 and negative active electrode 11 of the backup power box can extend from the side and be attracted by the magnetic component 12 (a rod magnet in this figure) and contact the conductive patch 9 on the upper side of the housing 1, so that the replacement battery 2 in the second housing 8 is connected in parallel with the replacement battery 2 in the housing 1, and the replacement battery 2 in the second housing 8 is connected in series with the control chip 5.

[0090] A control terminal is set up, which can be a remote control, mobile phone software, or other forms. This allows the control terminal to send a signal to the battery modification structure to cut off the power to the control chip 5. This is convenient for situations where the user is not indoors but needs to turn off the indoor gas supply, such as when cooking food and needing to turn off the stove on time, or when someone suddenly needs to be away from home for an extended period and cannot return to turn off the gas valve.

[0091] The specific connection relationship between the battery modification structure of this invention, the battery, and the gas meter is shown in the appendix. Figure 6 and 7As shown, the positive conductive part 3, the negative conductive part 4, the gas meter, and the power-off switch are connected in series on the main circuit. Between the positive conductive part 3 and the negative conductive part 4, there are two parallel circuits: one is a branch from positive conductive part 3 to power-off switch 23 to power-off element 21 to signal receiving element 7 to boost module 22 (removable) to negative conductive part 4; the other is a branch from positive conductive part 3 to power-off switch 23 to battery to negative conductive part 4. With this connection, when power-off switch 23 is on, current flows from the positive conductive part 3 to the negative conductive part 4 through the two parallel circuits, powering the gas meter and the battery modification structure. When power-off switch 23 is off, the gas meter loses power and stops working. Between the positive conductive part 3 and the negative conductive part 4, a series circuit is formed from battery to power-off element 21 to signal receiving element 7 to boost module 22 (removable) to battery, powering the battery modification structure.

[0092] Taking the application of this invention to gas shut-off as an example, the following explanation is provided: Domestic natural gas pipelines are laid and installed by natural gas companies, and gas meters are also provided by these companies. Natural gas companies conduct regular inspections to ensure a safe gas supply. Currently, gas shut-off devices include adding complex structures to close the gas valves on the original natural gas pipelines, or installing automatic shut-off valves on the gas pipelines. The first method suffers from complex structures and high costs, while the second violates the management regulations of the natural gas company and poses safety hazards.

[0093] Gas meters supplied by natural gas companies typically have multiple batteries connected in series to power them, usually AA batteries. When one battery runs out of power, the solenoid valve inside the gas meter closes, thus cutting off the gas supply. This patent utilizes this action of the gas meter to achieve a safe and simple gas shut-off.

[0094] To illustrate with a specific embodiment, the battery modification structure includes a housing 1, the size of which matches the size of the original gas meter's AA battery. A AAA replacement battery is installed in the housing 1, allowing the housing to be inserted into the original gas meter's battery slot without modifying the gas meter itself. Taking the example of the control chip 5 being electrically connected between the positive conductive part 3 and the positive terminal of the AAA battery (of course, the control chip 5 can also be electrically connected between the negative conductive part 4 and the negative terminal of the battery), the AAA battery is installed between the negative conductive part 4 and the conductive element 24. The negative conductive part 4 and the conductive element 24 can be conductive plates at both ends of a conventional battery mounting slot. For example, the negative conductive part 4 can also be equipped with a torsion spring for conducting electricity and pressing the battery. A partition 6 (which can be an insulating component, or it can be non-contacting with either the conductive component 24 or the positive conductive part 3) is provided between the conductive component 24 and the positive conductive part 3, ensuring that the positive terminal of the battery is not directly connected to the positive conductive part 3. The control chip 5 is electrically connected between the conductive component 24 and the positive conductive part 3 (or the conductive component 24 can be omitted, and the control chip can be directly connected to the positive terminal of the battery). Thus, when powering the gas meter, the circuit flow is as follows: battery positive terminal - conductive component 24 - control chip 5 - positive conductive part 3 (i.e., when powering the gas meter, the control chip 5 is connected in series between the No. 7 battery and the positive conductive part 3). When the control chip 5 is open-circuited, although the positive conductive part 3 and the negative conductive part 4 of the housing 1 are connected to the original gas meter battery compartment, they are not conductive. When the control chip 5 is closed-circuited, the No. 7 battery supplies power to the gas meter in the aforementioned current direction. When the main unit detects that the gas concentration exceeds the standard (gas leak), or when the timer set by the main unit reaches the preset time, it will send a signal to the control chip 5. The control chip 5 will cut off the power supply (the control chip can be cut off by a traditional MOS switch. Since the signal receiving module and switch module of the control chip are conventional existing technologies, they will not be described in detail in this manual), thereby cutting off the power supply of the No. 7 battery. The gas meter will not have a power supply, thus cutting off the gas supply.

[0095] In addition, the No. 7 battery powers both the gas meter and the control chip 5 via the circuitry. Since the No. 7 battery has less charge than the original No. 5 battery, it needs to be replaced more frequently. To extend the replacement cycle, this patent also includes a backup power box. The backup power box can have the same casing as the No. 7 battery, but it does not contain the control chip 5. The No. 7 battery inside the backup power box can be considered a backup battery (although it is a backup battery, it still needs to continuously power the gas meter and can also serve as a secondary power source for the control chip). The backup power box replaces the original No. 5 battery in the gas meter. The backup battery and the modified No. 7 battery are connected in series to power the gas meter. The backup power box has a positive active electrode 10 and a negative active electrode 11 electrically connected to the positive and negative terminals of the backup battery, respectively. This allows the backup battery to power not only the gas meter but also the control chip 5. The No. 7 battery and the backup battery are connected in parallel to power the control chip 5, further extending the battery replacement frequency.

[0096] In summary, those skilled in the art, after reading this invention document, can make various other corresponding modifications to the technical solutions and concepts based on this invention without creative mental effort. Different application scenarios all fall within the scope of protection of this invention.
