[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the specific details described below are only part of the embodiments of the present invention, and the present invention can also be implemented in many other embodiments different from those described herein. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present invention.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] In order to solve the technical problem that after the aluminum-air mobile power supply in the prior art finishes charging the battery, the chemical reaction continues and the chemical reaction cannot be stopped autonomously, resulting in waste of alkaline aqueous solution, the present invention provides a charging component and an aluminum-air mobile power supply, which can realize autonomous control of the charging component to stop charging the battery, thereby avoiding waste of alkaline aqueous solution.

[0030] It should be noted that the charging component described in the present invention is used for but not limited to aluminum air mobile power supplies, etc. For the convenience of explanation, in the present invention, only the application of the charging component to the aluminum air mobile power supply is used as an example for explanation, and the principles of the application of the charging component to other types of equipment are essentially the same as those applied to the aluminum air mobile power supply, which will not be repeated here.

[0031] See also Figure 1 , Figure 1 The structure diagram of the aluminum-air mobile power supply in one embodiment of the present invention is shown. The aluminum-air mobile power supply can be used outdoors when there is no access to the mains, for example, to power a barbecue grill outdoors, to power electronic products such as mobile phones, etc. The aluminum-air mobile power supply has a charging component 100 and a battery module 200. The battery module 200 is used to store electrical energy and connect to electrical equipment so as to power the electrical equipment when there is no access to the mains. The charging component 100 is connected to the battery module 200 and can charge the battery module 200 through the aluminum-air chemical reaction. When charging is not needed, the charging component 100 can be controlled to suspend the aluminum-air chemical reaction, which is convenient to use and can also avoid wasting alkaline aqueous solution.

[0032] The charging assembly 100 includes a reaction mechanism 1 and a control mechanism 2. The reaction mechanism 1 includes a reaction shell 11, an anode component 12 and a cathode component 13. The reaction shell 11 is provided with a reaction chamber 111 and a vent 112. The reaction chamber 111 is connected to the external air through the vent 112. The anode component 12 and the cathode component 13 are both arranged in the reaction chamber 111.

[0033] The control mechanism 2 includes a storage box 21, a negative pressure pump 22 and a pipette 23. The storage box 21 has a storage chamber 211. The pipette 23 connects the storage chamber 211 and the reaction chamber 111. The negative pressure pump 22 is connected to the pipette 23 and can drive the pipette 23 to suck the solution in the reaction chamber 111, such as an alkaline aqueous solution.

[0034] In this embodiment, the reaction chamber 111 can be used to store alkaline aqueous solutions such as sodium hydroxide or potassium hydroxide. The anode member 12 can be high-purity metal aluminum. When the cathode member 13 contacts the air (oxygen), the reaction chamber 111 can undergo an aluminum-air chemical reaction. The anode member 12 and the cathode member 13 are electrically connected to the battery module 200, so the battery module 200 can be charged and the battery module 200 can be powered. When it is not necessary to charge the battery module 200, the negative pressure pump 22 can be started to work. The negative pressure pump 22 sucks the alkaline aqueous solution of the reaction chamber 111 through the suction tube 23 so that the alkaline aqueous solution enters the storage chamber 211 for temporary storage. The anode member 12 and the cathode member 13 will stop the chemical reaction when they are not in contact with the alkaline aqueous solution, and will not continue to consume the alkaline aqueous solution. When it is necessary to continue to charge the battery module 200, the alkaline aqueous solution in the storage chamber 211 is released to the reaction chamber 111 to continue to charge the battery module 200 through the aluminum-air chemical reaction.

[0035] In one embodiment, see Figure 3 The suction pipe 23 is provided with a plurality of overflow holes 231 along the circumference of the storage chamber 211, and the negative pressure pump 22 can suck the alkaline aqueous solution in the reaction chamber 111 through the plurality of overflow holes 231 and flow into the storage chamber 211. In this embodiment, the overflow holes 231 are provided at the position where the suction pipe 23 is located in the storage chamber 211, and after the solution is sucked up by the negative pressure pump 22, the solution overflows into the storage chamber 211 through the plurality of overflow holes 231 at the same time, which is conducive to improving the storage efficiency of the solution.

[0036] For further information, see Figure 4 The suction pipe 23 includes a tube body 232 and an overflow pipe 233 which are connected to each other. One end of the overflow pipe 233 is connected to the tube body 232, and the other end is connected to the negative pressure pump 22. The overflow pipe 233 is located in the storage chamber 211 and has a plurality of overflow holes 231 along its circumference. One end of the tube body 232 away from the overflow pipe 233 is connected to the reaction chamber 111. The diameter of the overflow pipe 233 is larger than the diameter of the tube body 232. In this embodiment, by setting the diameter of the overflow pipe 233 larger than the diameter of the tube body 232, the space for storing the solution in the overflow pipe 233 can be increased, and the risk of the solution contacting the negative pressure pump 22 can be reduced. In addition, the overflow pipe 233 has a plurality of overflow holes 231 along its circumference, which can not only improve the efficiency of sucking the solution, but also further prevent the solution from contacting the negative pressure pump 22.

[0037] For further information, see Figure 4 The suction pipe 23 also includes an overflow prevention pipe 234, the diameter of which is larger than that of the overflow pipe 233, and the two ends of the overflow prevention pipe 234 are respectively connected to the overflow pipe 233 and the negative pressure pump 22. In this embodiment, the overflow prevention pipe 234 can further prevent the solution from contacting the negative pressure pump 22, thereby providing a better protection for the negative pressure pump 22. In order to further improve the protection, a waterproof and breathable membrane can be provided at the air inlet of the negative pressure pump 22.

[0038] In one embodiment, see Figure 5 and Figure 6 , there are multiple reaction chambers 111, each reaction chamber 111 is provided with an anode member 12 and a cathode member 13, the number of suction pipes 23, the number of negative pressure pumps 22 and the number of reaction chambers 111 are consistent, one end of the multiple suction pipes 23 are connected to the storage chamber 211, and the other end of the multiple suction pipes 23 is connected to the multiple reaction chambers 111, and each negative pressure pump 22 is connected to the corresponding suction pipe 23 and is used to suck the solution in the corresponding reaction chamber 111 into the storage chamber 211. In this embodiment, the multiple reaction chambers 111 can be provided with alkaline aqueous solution, and the anode member 12 and the cathode member 13 of each reaction chamber 111 can charge the battery module 200 through the aluminum-air chemical reaction, so as to improve the charging efficiency of the battery module 200. In addition, when charging is not required, the multiple negative pressure pumps 22 can be controlled to suck the alkaline aqueous solution of the corresponding reaction chamber 111 into the storage chamber 211 at the same time. Multiple negative pressure pumps 22 can be connected in series to the same control panel, so that multiple negative pressure pumps 22 can be controlled by one button to simultaneously pump alkaline aqueous solution into the storage chamber 211, and charging can be stopped by one button. In addition, multiple negative pressure pumps 22 can be managed in batches, for example, some negative pressure pumps 22 can be controlled in series, and other negative pressure pumps 22 can be controlled in series. According to charging needs, only some negative pressure pumps 22 can be controlled to pump alkaline aqueous solution into the storage chamber 211, and the reaction chamber 111 of the other part continues to charge the battery module 200 through reaction, thereby reducing the charging speed.

[0039] In one embodiment, there are multiple reaction chambers 111, each reaction chamber 111 is provided with an anode member 12 and a cathode member 13, and the suction pipe 23 includes a main pipe and multiple branch pipes (not shown in the figure), one end of the multiple branch pipes is connected to the multiple reaction chambers 111, and the other end is connected to the main pipe, and the main pipe is connected to the negative pressure pump 22. In this embodiment, the alkaline aqueous solution in all the reaction chambers 111 can be sucked into the storage chamber 211 for temporary storage by controlling only one negative pressure pump 22, which saves the cost of setting up the negative pressure pump 22 and is convenient to control. In addition, multiple anode members 12 can be connected in series with wires to the negative electrode of the battery module 200, and multiple cathode members 13 can be connected in series with wires to the positive electrode of the battery module 200.

[0040] In one embodiment, see Figure 2 The storage chamber 211 is provided with a plurality of ventilation pipes 14, and the plurality of ventilation pipes 14 are arranged corresponding to the plurality of reaction chambers 111. One end of each ventilation pipe 14 is connected to the corresponding reaction chamber 111, and the other end is connected to the storage chamber 111. A ventilation hole is provided on the top of the storage box 21, and a ventilation cover 15 is threadedly connected to the ventilation hole. When the ventilation cover 15 is opened, the storage chamber 211 is connected to the outside air. The plurality of ventilation pipes 14 are connected to the outside air, so that the negative pressure pump 22 can suck the solution in the reaction chamber 111 into the storage chamber 211 when working.

[0041] In one embodiment, see Figure 7 The bottom of the storage chamber 211 is inclined, and a liquid outlet 212 is provided at a lower position. The reaction shell 11 is slidably connected with a slider 213, and the slider 213 can open or close the liquid outlet 212 when sliding. When the liquid outlet 212 is opened, the liquid outlet 212 connects the storage chamber 211 and the reaction chamber 111, and the solution in the storage chamber 211 can flow downward into the reaction chamber 111 through the liquid outlet 212. In this embodiment, when it is necessary to stop charging, the slider 213 can be controlled to close the liquid outlet 212 first, and then the negative pressure pump 22 can be controlled to suck the solution in the reaction chamber 111 into the storage chamber 211. When it is necessary to recharge, the slider 213 can be controlled to slide open the liquid outlet 212, so that the alkaline aqueous solution in the storage chamber 211 can flow downward into the reaction chamber 111 through the liquid outlet 212 by gravity, and contact with the anode member 12 and the cathode member 13 to cause aluminum-air chemical reaction. The bottom of the storage chamber 211 of this embodiment is inclined, so that the solution in the storage chamber 211 can gather toward the lower liquid outlet 212, so that the solution in the storage chamber 211 can fully flow into the reaction chamber 111 when the liquid outlet 212 is opened. The slider 213 is connected to a handle 214, and the handle 214 extends outside the storage box 21, so that the user can operate the handle 214 to control the slider 213 to slide back and forth, so as to open or close the liquid outlet 212.

[0042] In one embodiment, see Figure 6, the reaction shell 11 is provided with a plurality of reaction chambers 111, and air passages 113 are formed between adjacent reaction chambers 111, and the air passages 113 are connected to the external air and the vents 112 on both sides. In this embodiment, the external air can pass through the air passage 113, and at the same time, supply air to the vents 112 on both sides of the air passage 113, and the air can enter the two reaction chambers 111 through the vents 112 on both sides, and contact the cathode parts 13 in the two reaction chambers 111, and provide the cathode parts 13 with oxygen required for the reaction. This structure is cleverly arranged, and can simultaneously supply oxygen to the cathode parts 13 of multiple reaction chambers 111, greatly improving the reaction efficiency of the aluminum-air chemical reaction, and having a high charging efficiency for the battery module 200. A plurality of vents 112 are provided on both sides of the air passage 113, and the contact area with the air is large, which can further improve the charging efficiency of the battery module 200. In addition, the reaction shell 11 is provided with a plurality of air inlet holes 117 along its circumference, and the plurality of air inlet holes 117 are connected to the air passage 113 and the external air at the same time, so that the air inlet area is large and sufficient air can be provided to the air passage 113 .

[0043] For further information, see Figure 6 The cathode member 13 is sealed against the vent hole 112 and absorbs air through the vent hole 112. In this embodiment, the cathode member 13 is sealed against the vent hole 112, which can not only prevent the alkaline aqueous solution in the reaction chamber 111 from leaking out, but also can contact the air in the air channel 113 through the vent hole 112 and smoothly participate in the chemical reaction.

[0044] In one embodiment, see Figure 1 A heat dissipation fan 16 is also provided on the side of the reaction shell 11, and the heat dissipation fan 16 can promptly remove the heat generated by the aluminum-air chemical reaction to avoid a large amount of heat accumulation in the reaction chamber 111 and affecting the reaction.

[0045] In one embodiment, see Figure 8This embodiment shows a schematic diagram of the structure of another embodiment of the control mechanism. In this embodiment, the negative pressure pump 22, the suction tube 23 and the storage box 21 mentioned above may not be provided. A wire reel 114 may be rotatably provided on the reaction shell 11. The wire reel 114 is provided with a plurality of wire grooves 115 arranged at intervals along its length direction. The plurality of wire grooves 115 are provided corresponding to the plurality of reaction chambers 111. Each wire groove 115 is wound with a thin wire 116, and the thin wire 116 is connected to the anode member 12 of the reaction chamber 111. When the battery module 200 needs to be charged, the wire reel 114 may be manually controlled to rotate to release the plurality of thin wires 116 at the same time, driving the plurality of anode members 12 to be lowered to the corresponding reaction chamber 111, and contacting with the alkaline aqueous solution in the reaction chamber 111, so as to charge the battery module 200 through the aluminum-air chemical reaction. When charging is not needed, the reel 114 can be manually controlled to reverse and reel in multiple thin wires 116, which simultaneously drive multiple anode components 12 to rise to separate from the alkaline aqueous solution in the reaction chamber 111, thereby stopping the reaction. Compared with the above-mentioned method of sucking the solution through the suction tube 23 by the negative pressure pump 22, the structure of this embodiment is simpler and more direct, and the operation is convenient. When the negative pressure pump 22 fails, the reaction can be stopped by rotating the reel 114.

[0046] In one embodiment, see Figure 5 The charging assembly 100 also includes a mounting shell 4, which has a mounting cavity 41 and is connected to the reaction shell 1 through the mounting cavity 41. The outer wall of the mounting shell 4 has a mounting socket 42 and a handle 43. In this embodiment, the mounting cavity 41 of the mounting shell 4 can be plugged in with the reaction shell 1 to complete the installation. The mounting socket 42 provided on the side wall of the mounting shell 4 can be used to be plugged in a preset installation position so as to fix the entire aluminum air mobile power supply at a preset installation position. For example, it can be installed on an outdoor trolley to facilitate carrying the aluminum air mobile power supply. There are two handles 43, which are respectively provided on both sides of the mounting shell 4 and can be used for users to carry the aluminum air mobile power supply by hand. In addition, a plurality of air inlets 44 are provided on the side wall of the mounting shell 4. When the reaction shell 1 is inserted into the mounting cavity 41 of the mounting shell 4, the air passage 113 of the reaction shell 1 corresponds to and is connected with the air inlets 44 of the mounting shell 4. External air can enter the air passage 113 through the air inlets 44 in sequence, and then contact the cathode component 13 through the vents 112, thereby providing the required oxygen for the cathode component 13 to react.

[0047] See also Figure 1The top of the mounting shell 4 is also provided with an active buckle 45, which is used to detachably connect the battery module 200 so that the positive and negative electrodes of the battery module 200 can be detachably connected to the anode member 2 and the cathode member 3. In this embodiment, the active buckle 45 is a commonly used buckle structure, and the specific structure is not redundantly described. In this embodiment, the active buckle 45 is provided to lock the battery and the battery module 200, so as to prevent the battery module 200 from being separated from the charging assembly 100 during the charging process.

[0048] In one embodiment, see Figure 1 The battery module 200 includes a housing 3 and a battery. The battery is located inside the housing 3 and is not shown. The positive and negative electrodes of the battery are connected to the anode 12 and the cathode 13, so that the anode 12 and the cathode 13 can charge the battery when the aluminum-air chemical reaction occurs. The surface of the housing 3 is provided with a power socket 31, a charging interface 32, a power switch 33 and a power display screen 34. The power socket 31 can be used to plug in the plug of the electrical device to power the electrical device. For example, the triangular plug of the electric fan can be plugged into the power socket 31, and the battery can power the electric fan to make the electric fan blow. The charging interface 32 can be a type-c interface or a USB interface, so that the charging cable can be plugged in, and the mobile phone and other electronic products can be charged through the charging cable. The power switch 33 is used to control the battery to work or not work. When the battery is required to provide power for work, the power switch 33 can be turned on. The power display screen 34 is used to display the remaining power of the battery to prompt the user whether the battery needs to be charged.
