Description

Technical Field

[0001] This utility model relates to the technical field of flashlights, and in particular to a fire emergency flashlight. Background Technology

[0002] A fire emergency flashlight is a handheld lighting tool designed specifically for responding to emergencies such as fires. It requires batteries to provide power for illumination. Emergency flashlights are usually only used in emergencies and are generally stored in a specific location without being used. However, the batteries will run out of power or lose power during storage. In an emergency, the battery may be depleted and unable to provide enough power for emergency lighting, which may even lead to serious consequences. Therefore, in the existing technology, an emergency flashlight using a metal-air battery has been developed on the market. However, when using it, it is necessary to manually open the container filled with salt water and then add salt water to the battery compartment to provide power for lighting, which is cumbersome. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a fire emergency flashlight that is simple in structure and easy to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fire emergency flashlight, comprising a flashlight body, an illumination component disposed at the front end of the flashlight body, and a metal-air battery disposed within the flashlight body, wherein the metal-air battery is electrically connected to the illumination component, and further comprising a bottle for holding saline solution, wherein a mounting base is rotatably connected to the rear end of the flashlight body, the bottle is fixedly mounted on the mounting base, a breakable part is provided at the bottle opening of the bottle, and a breakable groove is provided between the flashlight body and the bottle for inserting and fixing the breakable part, and such that when the mounting base drives the bottle to rotate relative to the flashlight body, the breakable part can be disconnected from the bottle.

[0005] By adopting the above technical solution, the metal-air battery is not powered under normal circumstances, and can only generate electrical energy when it comes into contact with salt water. Therefore, the metal-air battery will not cause power loss during storage, making the emergency flashlight have a longer storage life and stronger practicality. The bottle connected to the tail of the flashlight body is used to hold the salt water to activate the metal-air battery. When the emergency flashlight is not in use, the salt water is sealed in the bottle body, ensuring that the salt water will not come into contact with the metal-air battery under normal conditions. When the emergency flashlight needs to be used, the operator only needs to rotate the mounting base. The bottle body, which is fixedly connected to the mounting base, rotates relative to the flashlight body with the mounting base. The setting of the screw-off groove is used to fix the screw-off part at one end of the bottle body. When the bottle body is subjected to force and rotates, shear stress is generated between the bottle body and the screw-off part, causing the bottle body to break away from the screw-off part and making the bottle body connected to the flashlight body. The salt water in the bottle is injected into the flashlight body to make it contact the metal-air battery, thereby activating the metal-air battery to power the lighting components. The operation is simple and more convenient to use.

[0006] The present invention is further provided that the bottle body and the broken part are either integral or separate.

[0007] By adopting the above technical solution, the bottle body and the broken part can be set separately. By setting a cap, the broken part is set at the end of the cap body, and the cap body and the bottle body are connected by a threaded seal, so that the bottle body can be reused. The two can also be molded as one piece, simplifying parts, facilitating installation, and saving costs.

[0008] The present invention further comprises: the bottle body is a retractable corrugated columnar shape.

[0009] By adopting the above technical solution, the corrugated design allows the bottle body to be squeezed like a telescopic cylinder, making it easier to completely squeeze out the salt water in the bottle at once and inject salt water more quickly, thereby improving the activation efficiency of the metal-air battery.

[0010] The present invention further comprises: the inner wall of the rear end of the flashlight body is connected to the outer wall of the mounting base by a thread; the mounting base includes a first mounting block and a second mounting block; the first mounting block and the second mounting block are arranged opposite each other to form an installation channel for inserting the bottle; a fixing member is provided in the installation channel; the fixing member is used to fix the position of the bottle so that it rotates synchronously with the mounting base.

[0011] By adopting the above technical solution, when assembling the mounting base, the broken part at one end of the bottle is first aligned with the direction of the breakage groove and inserted to achieve a pre-positioning function. Then, the first mounting block and the second mounting block are arranged opposite each other, enclosing the bottle in the installation channel formed by the two. The bottle is then fixed in the installation channel position by a fastener. The bottle is made of flexible material, and there is a gap between the first and second mounting blocks when they are arranged opposite each other. This allows the operator to squeeze the first and second mounting blocks relative to each other when the mounting base, along with the bottle, continues to be inserted along the rear end of the flashlight body. This allows the external threads of the first and second mounting blocks to be matched and screwed into the flashlight body. Pre-installing the bottle before installing the first and second mounting blocks facilitates subsequent matching and screwing with the flashlight body, making installation convenient. The mounting base and the inner wall of the rear end of the flashlight body can also be installed through the cooperation of the limiting ring groove and the limiting protrusion, which can also achieve the effect of rotating the bottle circumferentially to break the broken part.

[0012] The present invention further includes the following: the fixing component includes a limiting ring, the limiting ring is disposed on the outer periphery of the bottle body, and the first mounting block and the second mounting block are each provided with a semi-annular groove that matches the limiting ring at the corresponding positions.

[0013] By adopting the above technical solution, the limiting ring is set to engage and insert with the semi-annular slots of the first mounting block and the second mounting block. After assembly, the mounting base and the bottle body are placed together into the rear end of the flashlight body. The three structures are compact, realizing the fixed installation of the bottle body. At the same time, when the mounting base rotates, the bottle body also rotates synchronously, improving structural consistency.

[0014] The present invention further comprises: the broken part includes a broken part and a connecting part, the connecting part is disposed between the bottle body and the broken part, and an inwardly recessed annular recess is provided at the connection between the broken part and the connecting part. The wall thickness of the annular recess is less than the wall thickness of the connecting part and also less than the wall thickness of the broken part.

[0015] By adopting the above technical solution, the setting of the annular recess reduces the width between the broken part and the connection part, while ensuring that the wall thickness of the annular recess is less than the wall thickness of the connection part and the broken part, so that the wall thickness of the annular recess is the minimum wall thickness. This is beneficial for the annular recess to break first when the bottle is rotated under the rotational torque, which saves more time and effort.

[0016] The present invention further includes a switch button on the flashlight body.

[0017] By adopting the above technical solution, the switch button is configured to control the lighting component on or off of the flashlight body.

[0018] The present invention further includes: the outer wall of the flashlight body is provided with multiple anti-slip blocks.

[0019] By adopting the above technical solutions, the contact area between the flashlight body and the hand is increased, preventing slippage and making it easier to hold, thus improving structural reliability. Additionally, structures such as fire hammers can be added to the outer wall of the flashlight body to further enhance its practicality. Attached Figure Description

Detailed Implementation

[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0027] See appendix Figure 1-5This utility model discloses a fire emergency flashlight, including a flashlight body 1, an illumination component 2 disposed at the front end of the flashlight body 1, and a metal-air battery 3 disposed inside the flashlight body 1. The metal-air battery 3 is electrically connected to the illumination component 2. It also includes a bottle 4 for holding salt water. A mounting base 5 is rotatably connected to the rear end of the flashlight body 1. The bottle 4 is fixedly mounted on the mounting base 5. A breakable part 6 is provided at the mouth of the bottle 4. A breakable groove 7 is provided between the flashlight body 1 and the bottle 4 for inserting and fixing the breakable part 6. When the mounting base 5 drives the bottle 4 to rotate relative to the flashlight body 1, the breakable part 6 can be disconnected from the bottle 4. The metal-air battery 3 is not powered under normal conditions; it is only activated to generate electricity when in contact with salt water. Therefore, the metal-air battery 3 does not suffer power loss during storage, resulting in a longer lifespan and greater practicality for the emergency flashlight. The bottle 4 connected to the tail of the flashlight body 1 is used to hold the salt water used to activate the metal-air battery 3. When the emergency flashlight is not in use, the salt water is sealed inside the bottle 4, ensuring that it does not come into contact with the metal-air battery 3 under normal conditions. When the emergency flashlight needs to be used, the operator only needs to rotate the mounting base 5. The bottle body 4, which is fixedly connected to the mounting base 5, rotates relative to the flashlight body 1 with the mounting base 5. The screw-off groove 7 is set to fix the screw-off part 6 at one end of the bottle body 4. When the bottle body 4 is subjected to force and rotates, shear stress is generated between the bottle body 4 and the screw-off part 6, causing the bottle body 4 to break away from the screw-off part 6 and making the bottle body 4 connected to the flashlight body 1. The salt water in the bottle body 4 is injected into the flashlight body 1 so that it contacts the metal-air battery 3, thereby activating the metal-air battery 3 to supply power to the lighting component 2. The operation is simple and the use is more convenient.

[0028] This embodiment further specifies that the bottle body 4 and the broken part 6 can be integrally formed or separately. The bottle body 4 and the broken part 6 can be separately formed by setting a cap, with the broken part 6 placed at the end of the cap, and the cap and bottle body 4 connected by a threaded seal, allowing the bottle body 4 to be reused. Alternatively, the two can be integrally formed, simplifying parts, facilitating installation, and saving costs.

[0029] This embodiment further specifies that the bottle body 4 is a retractable corrugated cylindrical shape. The corrugated design allows the bottle body 4 to be squeezed like a telescopic cylinder, making it easier to completely squeeze out the salt water inside the bottle body 4 at once and inject salt water more quickly, thereby improving the activation efficiency of the metal-air battery 3.

[0030] This embodiment further includes the following configuration: the inner wall of the rear end of the flashlight body 1 is threadedly connected to the outer wall of the mounting base 5. The mounting base 5 includes a first mounting block 501 and a second mounting block 502. The first mounting block 501 and the second mounting block 502 are arranged opposite each other to form an installation channel 8 for inserting the bottle body 4. A fixing member 9 is provided in the installation channel 8 to fix the position of the bottle body 4 so that it rotates synchronously with the mounting base 5. When assembling the mounting base 5, the broken part 6 at one end of the bottle body 4 is first inserted into the direction of the broken groove 7 to achieve a pre-positioning function. Then, the first mounting block 501 and the second mounting block 502 are arranged opposite each other to wrap the bottle body 4 in the installation channel 8 formed by the two. The fixing member 9 is used to fix the bottle body 4 in the position of the installation channel 8. The bottle body 4 is made of flexible material, and there is a gap between the first mounting block 501 and the second mounting block 502 when they are arranged opposite each other, so that when the mounting base 5 continues to insert the bottle body 4 along the rear end of the flashlight body 1, the operator can move relatively... When the first mounting block 501 and the second mounting block 502 are squeezed, they are smoothly inserted into the flashlight body 1, so that their external threads are matched with the internal threads of the flashlight body 1 for screwing. The bottle body 4 is pre-installed before the first mounting block 501 and the second mounting block 502 are installed, which facilitates the subsequent matching and screwing with the flashlight body 1 and makes installation convenient. The mounting base 5 and the inner wall of the rear end of the flashlight body 1 can also be installed through the cooperation of the groove of the limiting ring 901 and the limiting protrusion, which can also achieve the effect of rotating the bottle body 4 circumferentially to break the broken part 6.

[0031] This embodiment further includes the following: the fixing component 9 includes a limiting ring 901, which is disposed on the outer periphery of the bottle body 4. The first mounting block 501 and the second mounting block 502 are each provided with a semi-annular groove 10 corresponding to the limiting ring 901. The limiting ring 901 is designed to engage and insert with the semi-annular grooves 10 of the first mounting block 501 and the second mounting block 502. After assembly, the mounting base 5 and the bottle body 4 are placed together at the rear end of the flashlight body 1. The three components are compactly structured, achieving a fixed installation of the bottle body 4. Simultaneously, when the mounting base 5 rotates, the bottle body 4 rotates synchronously, improving structural consistency.

[0032] This embodiment further includes the following configuration: the broken part 6 comprises a broken portion 601 and a connecting portion 602. The connecting portion 602 is disposed between the bottle body 4 and the broken portion 601. An inwardly recessed annular recess 11 is provided at the connection between the broken portion 601 and the connecting portion 602. The wall thickness of the annular recess 11 is less than the wall thickness of both the connecting portion 602 and the broken portion 601. The annular recess 11 reduces the width between the broken portion 601 and the connecting portion 602, while ensuring that the wall thickness of the annular recess 11 is less than the wall thickness of both the connecting portion 602 and the broken portion 601. This minimizes the wall thickness of the annular recess 11, which is beneficial for the annular recess 11 to break preferentially during the rotation of the bottle body 4 under the influence of rotational torque, thus saving time and effort.

[0033] This embodiment further includes a switch button 12 on the flashlight body 1. The switch button 12 is used to control the lighting component 2 on or off on the flashlight body 1.

[0034] This embodiment further includes the following feature: multiple anti-slip blocks 13 are provided on the outer wall of the flashlight body 1. This increases the contact area between the flashlight body 1 and the hand, prevents slippage, makes it easier to hold, and improves structural reliability. Additionally, structures such as fire hammers can be added to the outer wall of the flashlight body 1 to further enhance the structural practicality.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
