Description

Technical Field

[0001] The utility model belongs to the technical field of charging protection, and in particular relates to a multi-socket charging fire protection device. Background Art

[0002] Multi-sockets are widely used in homes or offices because they can overcome the distance problem or the shortage of sockets of wall-mounted sockets. The fire problem caused by multi-sockets is a major cause of indoor fires. The quality of multi-sockets on the market varies. Poor quality, overload, aging, long-term power supply and other problems may lead to fires. Different electrical devices are connected to the sockets. Improper charging of electrical devices may also lead to fires. For example, thermal runaway occurs when charging a mobile phone or an irregular charging cable is used. Once a lithium battery catches fire, it will spread rapidly.

[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] It should be noted that the following detailed descriptions are exemplary and are intended to provide further description of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0029] In the present invention, terms such as "upper", "lower", "side", "bottom", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are relational words determined only for the convenience of describing the structural relationships of the various parts or elements of the present invention. They do not specifically refer to any part or element in the present invention and cannot be understood as limitations on the present invention.

[0030] In the present invention, terms such as "connection" should be understood in a broad sense, indicating that it can be fixedly connected, integrally connected or detachably connected; it can be directly connected or indirectly connected through an intermediate medium. Those skilled in the art can determine the specific meaning of the above terms in the present invention according to specific circumstances, and they cannot be understood as limiting the present invention.

[0031] In the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0032] One or more embodiments of the present utility model provide a multi-socket 2 charging fire protection device, such as Figure 1 As shown, it includes a main shell 1; the base 3 of the main shell 1 is detachable, an aerosol fire extinguishing core is provided in the base 3, and a plurality of jet holes 4 are provided on the top surface of the base 3; the main shell 1 is used to place a multi-socket 2, and the multi-socket 2 can supply power to a plurality of electrical devices 8; one or more vertical openings (not shown in the figure) are provided on the side of the main shell 1, and the top or bottom of the openings extend to the edge of the main shell 1, so as to facilitate the passage of the power cord of the multi-socket 2 or the power cord of the electrical device 8 plugged into the socket.

[0033] In order to ensure that the fire extinguishing core is triggered in time, in some embodiments, a passive triggering method is adopted. Specifically, a thermal wire is connected to the aerosol fire extinguishing core. The thermal wire can be arranged below the upper surface of the base 3, or it can extend to the inner surface of the main shell 1, so as to respond to the fire more quickly. When a fire occurs, the high-temperature thermal radiation will ignite the thermal wire, and the thermal wire will bring sparks into the base 3, thereby igniting the fire extinguishing core. In order to enable the fire extinguishing core to be ignited in time, a strip groove is provided on one end face of the fire extinguishing core. The size of the groove can be embedded in the thermal wire, so that the thermal wire and the fire extinguishing core can be fully in contact, so that the fire extinguishing core can be quickly ignited when a fire occurs.

[0034] In some embodiments, an active triggering method is adopted. Specifically, a heating wire is connected to the aerosol fire extinguishing core, and a control unit is also provided in the base 3. The heating wire is connected to the control unit through a control line; a temperature sensor and a smoke sensor are also provided in the main shell 1, both of which are connected to the control unit. When the temperature sensor and / or the smoke sensor sense an abnormality, the control unit energizes the heating wire to ignite the fire extinguishing core. In addition, a network interface is also provided in the base 3, which is connected to the control unit. The control unit can be connected to the user terminal via the network interface, and then when an abnormal situation occurs, it is pushed to the user in time, so that the user can remotely learn about the fire, trigger the heating wire to energize, and escape from the scene in time. Those skilled in the art can understand that the above control process is all prior art and will not be elaborated in detail here (for related technologies, please refer to CN218833436U, CN219815144U, etc.). Among them, the control unit can be implemented by a processor such as DSP or a programmable logic chip, such as a 51 series single-chip microcomputer, and technicians in this field can choose a specific model according to actual conditions. According to the chip manual, its circuit structure and connection with its peripheral circuits are all prior art.

[0035] When a fire occurs in the main shell 1, the fire extinguishing agent is ignited, and then aerosol is sprayed out through the jet holes 4 above the base 3, which immediately puts out the open flame of the fire source and continuously suppresses it to prevent re-ignition.

[0036] In some embodiments, the aerosol fire extinguishing core uses potassium ion fire extinguishing agent. The ionic potassium oxide released by the combustion of potassium ion fire extinguishing agent has a universal uniform effect, can fully flood the entire protection space, and combines with flame free radicals when contacting the fire source, repeatedly cutting off the flame free radical reaction chain, forming stable non-combustible products, and finally causing the flame chain to be interrupted, achieving the purpose of fire extinguishing. The gas released by the potassium ion fire extinguishing agent can be suspended in the protected main shell 1 for at least 30 minutes, effectively and continuously suppressing the expansion or re-ignition of the fire.

[0037] The temperature of the aerosol emitted when the fire extinguishing core is ignited is very high, and the extension cord socket is mostly installed indoors, and the installation positions are various. For example, it is placed on a bedside table to plug in the power cords of electrical devices 8 such as mobile phones and table lamps. Another example is placed on a desk to plug in the power cords of electrical devices 8 such as laptops. In these application scenarios, the distance between the socket and the human body is relatively close. If the fire extinguishing core is directly ejected when the fire extinguishing core burns, it is easy to cause harm to the human body. Based on this, two base 3 structural forms are designed: a flat base 3 and a grooved base 3.

[0038]

Flat base

[0039] like Figure 2As shown, the base 3 is a flat plate as a whole, and a receiving cavity 5 is provided in the middle of the base 3 for placing one or more fire extinguishing cores. The receiving cavity 5 is provided with an opening, and a plurality of gas injection holes 4 are arranged along the edge of the top surface of the base 3. Based on this, the distance between the fire extinguishing core and the gas injection hole is maximized, which can achieve a certain cooling effect. At the same time, the injection hole is arranged along the circumference of the top surface of the base 3, which can also prevent the socket inside the main shell 1 from blocking the gas injection hole 4 and affecting the fire extinguishing efficiency.

[0040] In order to further reduce the aerosol spray temperature, in some embodiments, a non-linear guide channel is provided between the opening of the accommodating cavity 5 and the gas jet hole 4, so that the distance between the fire extinguishing core and the gas jet outlet is further extended, thereby reducing the temperature to a lower level and avoiding harm to the surrounding human body.

[0041] The guide channel includes one or more baffles 6 along the outlet direction of the accommodating chamber 5 to the air injection hole 4, so that the sprayed aerosol cannot directly reach the air injection hole 4 after being blocked for multiple times.

[0042] As a specific implementation method, Figure 5 As shown, the guide channel includes a spiral baffle 6 arranged at the opening of the accommodating chamber 5. At this time, the area above the outer side surface of the end of the spiral baffle 6 and the side wall of the base 3 corresponds to the position of the jet hole 4. Those skilled in the art can understand that the spiral baffle 6 can be an integrated baffle 6 or a plurality of baffles 6 connected to each other.

[0043] As another specific implementation method, Figure 3 and Figure 4 As shown, the guide channel includes at least two layers of baffles 6 surrounding the accommodating bin, each layer of baffles 6 is provided with openings, and the openings of two adjacent layers of baffles 6 are staggered.

[0044]

Groove type base

[0045] like Figure 8 As shown, the base 3 is based on the flat base 3, and a groove matching the size of the socket is set in the middle of the upper surface, which is convenient for placing the socket in the main housing 1. A receiving cavity 5 is set in the cavity surrounding the groove in the base 3, which is used to place one or more fire extinguishing cores. The receiving cavity 5 is provided with an opening. From the opening, an annular guide channel 10 is set in the cavity surrounding the groove in the base 3, and an injection hole 4 is provided on the upper surface of the end of the annular guide channel 10.

[0046] When using the protection device, the user inserts the socket into the groove, then sleeves the main housing 1 on the outside of the base 3, and the power cord passes through the side opening. When charging the electric device 8, the main housing 1 is removed from the base 3, the plug of the electric device 8 is plugged into the socket, and then the main housing 1 is sleeved on the outside of the base 3, and the power cord of the electric device 8 also passes through the side opening.

[0047] It is worth noting that in addition to the possibility of fire caused by problems with the socket strip itself during charging, improper charging of the electrical device 8 may also cause a fire, such as thermal runaway when charging a mobile phone or using an irregular charging cable. In order to address the hidden dangers that may be caused by the electrical device 8, the protection device is also provided with a storage space for placing the electrical device 8.

[0048] As a specific implementation method, Figure 1 and Figure 6 As shown, the main shell is open at the top, and an upper shell 7 is also provided above the main shell for placing electric devices 8 such as mobile phones; the upper shell 7 is open at the side for placing or taking out the electric devices 8, and a plurality of through holes are provided on the bottom surface of the upper shell 7, so that the gas ejected from the fire extinguishing core can enter the upper shell 7 to extinguish the electric devices 8. Those skilled in the art can understand that the upper shell 7 can be located in the external space above the main shell, and a connecting portion is provided below to be sealedly connected to the upper part of the main shell, for example, a recessed portion is provided circumferentially below the outer side surface of the upper shell, and when connected to the main shell, the recessed portion is sleeved on the inner side surface of the main shell; or the upper shell can be integrally embedded in the main shell, for example, a hanging portion is provided at the edge of the opening on the upper shell to be hung in the upper internal space of the main shell.

[0049] As another specific implementation method, Figure 7 As shown, part of the top surface of the main shell is recessed downward to form a storage groove 9 for placing electrical equipment 8. As an example, the edge of the top surface of the main shell is recessed downward to form a longitudinal storage groove 9, and the side of the storage groove 9 is provided with multiple through holes connected to the internal space of the main shell. The longitudinal groove enables a tablet-type electrical equipment 8 such as a mobile phone to be inserted longitudinally, so that it can fully contact the gas on the side when extinguishing a fire. At the same time, since the upper opening of the longitudinal storage groove 9 is small, the gas overflow is limited, and the entire device is still approximately a sealed space, ensuring the fire extinguishing efficiency.

[0050] Based on this, when the electrical equipment is on fire, the fire extinguishing agent can be ignited to extinguish the fire. The charging fire protection device of the utility model can protect the socket and the electrical equipment plugged therein, thereby ensuring the safety of indoor electricity use.

[0051] The protection scope of the present invention is limited only by the claims. Thanks to the teachings of the present invention, those skilled in the art will easily recognize that alternative structures to the structures disclosed in the present invention can be used as feasible alternative embodiments, and the embodiments disclosed in the present invention can be combined to generate new embodiments, which also fall within the scope of the appended claims.
