Description

Technical Field

[0001] This application belongs to the field of fire extinguisher technology, and in particular relates to a lithium battery-powered portable fire extinguisher. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. When a lithium battery catches fire, it needs to be extinguished with a fire extinguisher. Most fire extinguishers used for lithium batteries are water-based fire extinguishers. Water-based fire extinguishers spray water mist, hence the name water mist fire extinguishers.

[0003] A Chinese patent with publication number CN220513317U discloses a portable water-based fire extinguisher, including a bottle body, an extinguishing agent inside the bottle body, and a nozzle inserted inside the extinguishing agent. A pressure gauge and a head assembly are installed on the top of the bottle body, and the end of the head assembly is fixedly connected to the spray hose. At the same time, the end of the spray hose away from the head assembly is fixed to the nozzle.

[0004] While the aforementioned fire extinguishers improve ease of use, they require one hand to hold the extinguisher and press the handle, while the other hand holds the hose. This makes them suitable only for holding the extinguisher with one hand for extended periods, which is quite strenuous, especially for people with limited strength. Improvements are needed to address this issue. Utility Model Content

[0005] The purpose of this application is to address the aforementioned technical problems by providing a lithium battery-powered portable fire extinguisher that improves the convenience of using the fire extinguisher and enhances its labor-saving performance.

[0006] This application provides a lithium battery-powered portable fire extinguisher, comprising:

[0007] The cylinder contains a fire extinguishing agent.

[0008] The head assembly is installed on the top of the cylinder, and the head assembly is provided with a flexible hose;

[0009] The support assembly is installed on the cylinder.

[0010] The bracket assembly includes a bracket sleeve and a movable component. The movable component is hinged to the bracket sleeve. The movable component is provided with a buckle portion that is adapted to a hose. A first locking mechanism is provided between the movable component and the bracket sleeve. The device head assembly includes a handle and a pressure handle. The handle is provided with a second locking mechanism adapted to the pressure handle.

[0011] Fire extinguishers extinguish fires by spraying extinguishing agent from the cylinder through the head assembly and hose. The extinguisher is mounted on the cylinder via a bracket assembly, with a bracket sleeve fixed to the cylinder. A hinged connection exists between the movable part and the bracket sleeve. A first locking mechanism controls the movable part to be fixed in two states: when the fire extinguisher is not in use, the movable part is in a retracted state; when the fire extinguisher needs to be used, the movable part rotates, and the first locking mechanism fixes it in the second state, aligning the hose nozzle with the nozzle. This frees the hand holding the hose, allowing the hand to support the bottom of the cylinder, making it easier to carry the extinguisher with one hand. The head assembly is mounted on the cylinder; the cylinder is lifted by the handle, and the extinguishing agent is sprayed by pressing the lever. During continuous use, pressing the lever for extended periods can cause hand fatigue; a second locking mechanism locks the lever, improving ease of use and reducing effort. A clip secures the hose; when the hose needs to be held, it is removed from the clip.

[0012] Furthermore, the first locking mechanism includes:

[0013] The first locking element is movably mounted on the bracket sleeve and is located on the side of the hinge axis between the movable element and the bracket sleeve.

[0014] The first elastic element is placed between the first locking element and the bracket sleeve;

[0015] The movable part is provided with a first locking groove corresponding to the first locking part, and the first locking part is provided with a first handle.

[0016] The first locking member is hinged to the bracket sleeve. When the movable member rotates, the first locking groove and the first locking member are engaged, and the movable member is locked by the first locking member. When it is necessary to unlock, the first locking member is separated from the first locking groove by pressing the handle. The first locking member is reset by the first elastic member, which is a spring or the like.

[0017] Furthermore, the first locking mechanism also includes:

[0018] The first permanent magnet is placed on the moving part;

[0019] The second permanent magnet is placed on the support sleeve;

[0020] The first permanent magnet and the second permanent magnet correspond to each other.

[0021] When the movable part is in the retracted state, the first permanent magnet and the second permanent magnet attract each other, which improves the structural stability between the movable part and the support sleeve.

[0022] Furthermore, the second locking mechanism includes:

[0023] The second locking element is movably mounted on the handle;

[0024] The second elastic element is placed on the second locking element and the handle;

[0025] The pressure handle is provided with a second locking groove corresponding to the second locking member, and the second locking member is provided with a second handle portion.

[0026] By pressing the pressure plate, the second locking groove engages with the second locking member, allowing the hose to continuously spray extinguishing agent even without continuous pressing of the pressure plate. The second handle is connected to the second locking member, facilitating the movement of the second locking member to separate it from the second locking groove. A second spring, such as a spring, is used to reset the second locking member.

[0027] Furthermore, the pressure handle is provided with a locking part, and the second locking groove is provided in a plurality of places and evenly distributed on the locking part. The handle is provided with a through hole corresponding to the locking part.

[0028] The locking part can move in the through hole, giving the handle a large angle of movement. By setting multiple second locking grooves, the speed of the fire extinguishing agent sprayed can be controlled by adjusting the handle under different degrees of pressure.

[0029] Furthermore, a handle is hinged to the bottom of the cylinder.

[0030] The handle is hinged to the bottom of the cylinder. When in use, the handle is rotated outside the cylinder for easy hand grip and convenient support of the bottom of the cylinder.

[0031] The beneficial effects of this application are:

[0032] 1. When the fire extinguisher is not in use, the movable part is in the retracted state. When the fire extinguisher needs to be used, the movable part rotates and the first locking mechanism fixes the movable part in the second state, so that the nozzle of the hose faces forward. The hand used to hold the hose is released to support the bottom of the cylinder, which is less strenuous than carrying the fire extinguisher with one hand.

[0033] 2. The extinguishing agent inside the cylinder is sprayed out by lifting the cylinder by the handle and pressing the lever. When the fire extinguisher is in continuous use, the second locking mechanism locks the lever, which facilitates use and improves the efficiency of saving effort.

[0034] 3. The buckle is used to secure the hose. When you need to hold the hose, remove the hose from the buckle. Attached Figure Description
