Description

Technical Field

[0001] The utility model relates to a battery, in particular to a multi-functional air battery. Background Art

[0002] An air battery is a special chemical battery. Its construction principle is similar to that of a dry battery, but the oxidant is taken from oxygen in the air. The electrolyte between the positive electrode and the negative electrode is responsible for accepting the electrons generated at the cathode and transporting them to the anode. This kind of battery has the advantages of light weight, convenient storage and transportation, strong mobility, high energy density, stable discharge voltage, long cycle service life, etc.

[0003] There are various types of air batteries, including aluminum-air batteries, magnesium-air batteries, zinc-air batteries, lithium-air batteries, etc. Among them, zinc-air batteries and aluminum-air batteries have practical applications.

[0004] In the prior art, due to the low stability and slow kinetics of the air cathode, as well as the low Coulomb efficiency and dendrite formation problems of the metal anode, the charging rate of the air battery is low. In other words, the power supply of the air battery to electrical equipment is small. For example, during the charging process of a smart phone, only slow charging can be carried out and fast charging cannot be achieved. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the utility model provides a multi-functional air battery, which has multiple functions such as power supply, lighting and ignition, and can realize boost output, so as to meet the power consumption requirements of electrical equipment such as smart phones.

[0006] The technical solution of the utility model is as follows:

[0007] A multi-functional air battery includes a housing, an air battery main body and a rechargeable battery. The air battery main body is built in the housing. A battery compartment is arranged at the bottom of the housing, and the rechargeable battery is detachably installed in the battery compartment. A charge and discharge circuit, a USB output circuit, a single-chip microcomputer, an LED circuit, a boost output circuit and an electronic lighter are arranged in the housing;

[0008] The air battery main body is electrically connected to the charge and discharge circuit, the rechargeable battery is electrically connected to the charge and discharge circuit, the charge and discharge circuit is electrically connected to the USB output circuit, the charge and discharge circuit is electrically connected to the single-chip microcomputer, and the single-chip microcomputer is respectively electrically connected to the LED circuit, the boost output circuit and the electronic lighter.

[0009] In a preferred embodiment of the present disclosure, the housing is in the shape of an arc-shaped frustum with a thinner upper part and a thicker lower part, and its function is to make the battery more stable when placed and not easy to tip over.

[0010] In a preferred embodiment of the present disclosure, an upper cover is provided on the top of the housing. The charging and discharging circuit, the single-chip microcomputer, and the electronic lighter are all installed below the upper cover. Button holes and ignition holes are respectively formed in the housing corresponding to the button of the single-chip microcomputer and the nozzle of the electronic lighter. The button holes and the ignition holes are arranged on the top surface for the convenience of user operation.

[0011] In a preferred embodiment of the present disclosure, air holes are provided on the upper cover, and the air holes are communicated with the air exchange channel of the air battery body, which is conducive to air circulation.

[0012] In a preferred embodiment of the present disclosure, a lampshade is provided around the upper part of the housing, and an LED light strip is arranged inside the lampshade. The LED light strip is electrically connected to the LED circuit. The annular LED located in the upper part of the housing is conducive to using this battery as a table lamp for lighting.

[0013] In a preferred embodiment of the present disclosure, a USB charging hole and a boost output charging hole are provided at the lower part of the housing. The USB charging hole and the boost output charging hole are electrically connected to the USB output circuit and the boost output circuit respectively. Users can choose slow charging or fast charging according to their needs.

[0014] In a preferred embodiment of the present disclosure, dust plugs are provided for both the USB charging hole and the boost output charging hole. This can prevent dust from blocking the charging holes.

[0015] In a preferred embodiment of the present disclosure, a hollowed-out part is provided on the outer periphery of the lower part of the housing. Oval small holes are evenly arranged horizontally in the hollowed-out part. The significance is to improve the buffering and deformation ability of the lower part of the housing when it is impacted by the ground through the oval small holes in the hollowed-out part, and the probability of the housing being severely cracked when the battery drops can be reduced.

[0016] In a preferred embodiment of the present disclosure, a plurality of rubber pads are provided at the bottom of the housing to improve the stability of the battery when placed.

[0017] In a preferred embodiment of the present disclosure, a fixing plate is installed in the battery compartment through bolts for fixing the rechargeable battery.

[0018] Advantages of the present utility model

[0019] According to the present disclosure, by connecting the rechargeable battery and the air battery body through the charging and discharging circuit, these two types of batteries form a dual-power supply system. When high-power power supply is required externally, the rechargeable battery serves as the power source. When conventional power supply is needed, either the air battery or the rechargeable battery can be used as the power source. When the power of the rechargeable battery is too low, the air battery can serve as the electrical energy input end to replenish power to the rechargeable battery. In addition, since this battery is also provided with an LED light strip, a USB charging hole, and an electronic lighter, it has the functions of lighting, power supply, and ignition.

[0027] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings:

[0028] As Figure 1 and 2 shown, a multifunctional air battery includes a housing 1, an air battery main body 12 and a rechargeable battery 14. The housing 1 is in the shape of an arc-shaped frustum with a thinner upper part and a thicker lower part. An upper cover 7 is provided at the top of the housing 1. An air battery main body 12, a battery compartment 2, a charge and discharge circuit 13, a USB output circuit 15, a single-chip microcomputer 16, an LED circuit 17, a boost output circuit 18 and an electronic igniter 19 are arranged inside the housing 1. The upper cover 7 is provided with an air hole 10, a button hole 8 and an ignition hole 9 corresponding to the air battery main body 12, the single-chip microcomputer 16 and the electronic igniter 19 therein. A rechargeable battery 14 is installed in the battery compartment 2. A fixing plate is connected to the bottom end of the battery compartment 2 by bolts, and the fixing plate fixes the rechargeable battery 14 in the battery compartment 2. A lamp shade 5 is sleeved on the upper part of the housing 1, an LED light strip is arranged inside the lamp shade 5, a hollowed-out part 4 is arranged at the lower part of the housing 1, elliptical small holes are uniformly arranged horizontally in the hollowed-out part 4, and a USB charging hole 11 and a boost output charging hole 3 are respectively arranged at the lower part of the housing 1 corresponding to the USB output circuit 15 and the boost output circuit 18. Four rubber pads 6 are also arranged at the bottom of the housing 1. In this embodiment, the rechargeable battery uses dry batteries.

[0029] AsFigure 3 As shown in the figure, the electrical connection structure of the present utility model is as follows:

[0030] The air battery main body 12 is electrically connected to the charge and discharge circuit 13, the rechargeable battery 14 is electrically connected to the charge and discharge circuit 13, the charge and discharge circuit 13 is electrically connected to the USB output circuit 15, the charge and discharge circuit 13 is electrically connected to the single-chip microcomputer 16, and the single-chip microcomputer 16 is respectively electrically connected to the LED circuit 17, the boost output circuit 18 and the electronic lighter 19;

[0031] The USB output circuit 15 is electrically connected to the USB charging hole 11, the boost output circuit 18 is electrically connected to the boost output charging hole 3, and the LED circuit 17 is electrically connected to the LED light strip.

[0032] The working principle of the present utility model:

[0033] A dual-power supply system is constituted by using the rechargeable battery and the air battery main body. Since the electricity storage capacity of the air battery is much larger than that of a common dry battery under the same volume, the air battery main body can be regarded as an electrical energy input end similar to a solar panel or a mains power supply for the rechargeable battery, so as to replenish the rechargeable battery with low power. Also, by taking advantage of the advantage that the rechargeable battery has a relatively large power supply capacity, the present battery supplies power when a relatively large power current needs to be output externally, such as quickly charging a smart phone. In addition to the power supply function, the present battery is also equipped with an LED light strip and an electronic lighter, and can realize the lighting and ignition functions.

[0034] Specifically, as Figures 3 - 6 shown, the positive electrode of the air battery main body 12 is connected to the positive electrode of the rechargeable battery 14 through the diode D1 of the charge and discharge circuit 13 in a one-way conduction manner. The negative electrode of the air battery main body 12 is grounded. The diode D1 plays a role of one-way conduction and current limiting. The negative electrode of the rechargeable battery 14 is grounded through a dual MOS transistor. The output terminals of the voltage regulator chip U7 supply power to the single-chip microcomputer 16, the USB output circuit 15, the LED circuit 17, the boost output circuit 18 and the electronic lighter 19 respectively. Among them, the USB output circuit 15 directly obtains the output of the voltage regulator chip U7 and does not require control by the single-chip microcomputer 16. Whether the LED circuit 17, the boost output circuit 18 and the electronic lighter 19 are connected to the voltage regulator chip U7 is controlled by the single-chip microcomputer 16. The control method can be button control or programming control, which are all prior arts and will not be elaborated.
