Description

Technical Field

[0001] This utility model relates to the field of emergency equipment, specifically to a portable aluminum air battery lamp. Background Technology

[0002] Current emergency power supplies are generally rechargeable, with internal lithium batteries. While they can meet emergency needs, their battery life is limited when encountering situations in the wild where power cannot be replenished. Once the internal power is depleted, they become useless. Furthermore, emergency power supplies are not typically used frequently in daily life and are only useful in rare situations. Therefore, even if they are fully charged and stored, they need to be replenished regularly, making maintenance troublesome and unable to meet long-term, stable, and reliable power supply needs under extreme conditions. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a portable aluminum air battery lamp that is small in size, light in weight, has a long storage time, and has good emergency reliability.

[0004] To address the above problems, the following technical solution is provided: A portable aluminum-air battery lamp, comprising a housing, wherein the housing has an installation port and forms a battery cavity inside it, and the housing also has a through hole communicating with the battery cavity; an aluminum-air battery is disposed inside the battery cavity, the aluminum-air battery comprising an electrode plate, a water-absorbing layer covering the electrode plate, and an electrode sheet covering the water-absorbing layer, wherein the electrode plate and the electrode sheet are both connected to a lead wire; the housing also has a lamp head cover located at the installation port, the lamp head cover having a light-emitting component and a light-emitting port, and the lead wire being electrically connected to the light-emitting component.

[0005] The present invention is further configured such that a sealing partition is provided inside the mounting port, and the light-emitting component is located on the side of the sealing partition facing away from the battery cavity; the outgoing wire passes through the sealing partition and is electrically connected to the light-emitting component, and the position where the outgoing wire passes through the sealing partition is sealed with sealant.

[0006] The present invention is further configured such that a buckle is provided inside the mounting port, and the sealing partition is fixed inside the mounting port by the buckle.

[0007] The present invention is further configured such that the outer edge of the sealing partition is sealed to the inner wall of the mounting port by a sealant / gasket.

[0008] The present invention is further configured such that the light-emitting component includes a mounting substrate, and the mounting substrate is provided with lamp beads and a control switch for controlling the lamp beads to light up and turn off.

[0009] The present invention is further configured such that a reflector bowl is provided on the mounting substrate, and the lamp bead is located at the bottom of the reflector bowl.

[0010] The present invention is further configured such that an electrolyte layer is sandwiched within the absorbent layer.

[0011] The present invention is further configured such that the through hole is single or multiple, located at the end face of the housing away from the mounting port and / or at the side wall away from the mounting port.

[0012] The present invention is further configured such that the absorbent layer is non-woven fabric or cotton, which fully covers the electrode plate; the electrode sheet is covered outside the absorbent layer and has an open area for the absorbent layer to contact the outside world.

[0013] The present invention is further configured such that the electrode sheet covers the side wall of the absorbent layer, and the open area is located at the end or side of the absorbent layer.

[0014] The present invention is further configured such that a snap-fit ​​edge is provided on the outer side of the mounting opening, a snap-fit ​​groove is provided on the outer wall of the snap-fit ​​edge, and a snap hook adapted to the snap-fit ​​groove is provided on the inner wall of the lamp head cover.

[0015] The present invention is further configured such that the electrode plate is an aluminum-magnesium electrode plate and the electrode sheet is a carbon film.

[0016] The beneficial effects of this utility model are:

[0017] 1. In storage, the water-absorbing layer of the aluminum-air battery is dry, allowing for long-term preservation and avoiding the self-discharge phenomenon of traditional batteries. When needed, electrolyte is added to the battery cavity through the through-hole. After the water-absorbing layer absorbs the electrolyte, the electrode plates undergo a chemical reaction and lose electrons. Together with the electrode plates, the electrical energy is sent to the light-emitting component through the lead wire to achieve emergency lighting. The electrolyte can be a pre-prepared salt solution or electrolyte particles (such as sodium chloride particles) embedded in the water-absorbing layer. Adding water causes the water-absorbing layer to absorb water and dissolve, forming the electrolyte.

[0018] 2. When the control switch is on, it connects the load to the aluminum-air battery and lights up the LED. When it needs to be turned off, the control switch is turned off. After the load is removed, the chemical reaction activity of the aluminum-air battery can be slowed down (it should be noted that the aluminum-air battery will not completely stop working after it starts).

[0019] 3. The electrolyte layer consists of electrolyte particles (such as sodium chloride particles), which allow the user to dissolve and form an electrolyte solution when water is added.

[0020] 4. The electrode plate has a plate-shaped structure. Therefore, the electrode sheet is preferentially covered on the two corresponding plate surfaces, while the sides or ends are not covered, so that the absorbent layer can be exposed to absorb water. Attached Figure Description
