[0028] As Figures 1 to 6 shown, the embodiment provides a car-use blowing and sucking dust collector with a detachable battery, which comprises a battery monomer 1 and a blowing and sucking dust collector body 2 capable of blowing dust and sucking dust, wherein the blowing and sucking dust collector body 2 is provided with a battery compartment 21, the battery compartment 21 is provided with a conductive plug 22, the conductive plug 22 is electrically connected with a circuit mainboard 23 inside the blowing and sucking dust collector body 2, the battery monomer 1 is provided with a conductive jack 11 matched with the conductive plug 22, the battery monomer 1 is internally provided with a circuit board 12 and a battery 14 electrically connected with the circuit board 12, the conductive jack 11 is electrically connected with the circuit board 12, the circuit board 12 is provided with a charging and discharging jack 13, the charging and discharging jack 13 is arranged outside the battery monomer 1, the battery monomer 1 is detachably inserted into the battery compartment 21, and the conductive plug 22 is inserted into the conductive jack 11.

[0029] The main design of the embodiment is to select the battery originally connected with the blowing and sucking dust collector body as a detachable structure, so that the battery can be detached, thereby avoiding the anxiety of endurance in daily use, and the battery or the blowing and sucking dust collector body 2 can be separated when one of them is damaged, so that they do not need to be scrapped together, thereby avoiding resource waste; at the same time, when placed in the car, the battery monomer 1 can be removed to avoid the battery monomer 1 being exposed to the sun together with the blowing and sucking dust collector body 2 in the car; in addition, after the battery monomer 1 is separated from the blowing and sucking dust collector body 2, it can also be used as a power bank, which is convenient and practical for car products. Specifically, when used as a power supply for a car-use blowing and sucking dust collector, the battery monomer 1 is directly inserted into the battery compartment 21, and then the conductive plug 22 and the conductive jack 11 are connected, so that the car-use blowing and sucking dust collector can be normally powered, and the basic power transmission principle is the same. When used as a power bank, it is necessary to charge itself and supply power to other electrical appliances, so the embodiment is characterized in that the circuit board 12 is integrated with a lithium battery protection circuit and a Type-C charging and discharging circuit, one end of the lithium battery protection circuit is connected with the battery, the other end of the lithium battery protection circuit is connected with the Type-C charging and discharging circuit, and the Type-C charging and discharging circuit is connected with the charging and discharging jack. As Figure 6 shown, the lithium battery protection circuit is composed of U1 (PT6303EMSJ, lithium battery protection controller with low static current) and peripheral components.

[0030] U1 (PT6303) is a battery protection chip specially designed for protecting 3 series of lithium ion / polymer batteries, which can reduce the risk of battery damage or shortened life caused by overcharge, overdischarge, overtemperature and / or overcurrent conditions. Built-in high-precision voltage detection circuit, built-in three-section discharge overcurrent detection circuit, it has multiple voltage comparators inside. B1, B2, B3 pins are internal overvoltage and undervoltage protection comparator input terminals, which will perform overvoltage and undervoltage detection on each cell voltage in real time. When the voltage detection value of any cell is greater than 4.2±0.025V or less than 2.7±0.05V, the comparator outputs high level, which turns off the charging MOS or discharging MOS through the internal logic circuit, thereby starting overvoltage or undervoltage protection.

[0031] Q1: MOS tube, is a charging switch MOS; R11 voltage sampling resistor, R2 overcurrent detection resistor, Q2: MOS tube is a discharging switch MOS, F3 charging and discharging short circuit protection: F1 or F2 11.1V output high-power discharge short circuit protection; TS pin is the overtemperature protection pin, which changes with temperature through R10, C11 and NTC resistance to protect the battery from overtemperature and low temperature during charging and discharging.

[0032] And for Type-C charging and discharging circuit, it is mainly composed of charging and discharging management chip IP2363 and its peripheral components. The power adapter is inserted into the Type-C interface through USB AtoC data line or USB C to C data line, which can charge the product with a maximum of 20V and a maximum of 30W. Through the Type-C interface communication PIN, it can automatically identify and match the voltage and current. When the USB C to C or USB C to Lightning data line is inserted into the Type-C interface, it can charge mobile phones, tablets, hand warmers, small fans, small table lamps, small night lights, notebook computers and other devices. At this time, it is used as a power bank function.

[0033] Further, in order to make the battery monomer 1 more beautiful when used alone, the battery cover 3 is detachably mounted on the battery monomer 1, so that when the battery monomer 1 is detached from the battery compartment 21, the battery cover 3 is mounted on the battery monomer 1, which can play a role in hiding the ugliness. Mainly because the battery monomer 1 will be provided with some structures for detachable mounting on the battery compartment 21, and these structures will affect the beauty if not shielded.

[0034] Further, for the specific detachable structure, specifically, a stopper 41 is arranged on the inner wall of the battery compartment 21 and the battery cover 3, the side surface of the battery monomer 1 is provided with two symmetrical elastic sheets 42, the end of the elastic sheet 42 is provided with a clamping convex 43 matched with the stopper 41, when the battery monomer 1 is inserted into the battery compartment 21 or the battery cover 3, the clamping convex 43 is lapped at the inner end surface of the stopper 41 after the elastic sheet 42 is deformed. That is, for the battery compartment 21 and the battery cover 3, the structure assembled inside the battery monomer 1 is the same, and the locking is formed by the elastic force of the elastic sheet 42 and the restriction between the clamping convex 43 and the stopper 41.

[0035] Further, in order to automatically complete the deformation of the elastic sheet 42 during insertion, the outer end surface of the stopper 41 of the embodiment is beveled, and the outer surface of the clamping convex 43 is beveled, so that during insertion, the elastic sheet 42 is deformed, and then the clamping convex 43 and the stopper 41 are restricted.

[0036] Further, for the separate disassembly of the battery monomer 1, it is necessary to deform the elastic sheet 42 again, so the side surface of the elastic sheet 42 of the embodiment is provided with a pressing part 44, and the pressing part 44 is arranged outside, so when unlocking is needed, only the pressing part 44 on the two elastic sheets 42 is clamped by two fingers, and the elastic sheets 42 on both sides are deformed synchronously, and then the battery monomer 1 can be pulled out outward.

[0037] Further, in order to play a role in preventing slipping, the top end of the battery cover 3 and the surface of the pressing part 44 of the embodiment are provided with anti-slip lines, wherein the anti-slip lines arranged on the top of the battery cover 3 are mainly used when the battery monomer 1 is used as a power bank, the battery cover 3 is placed downward, and the anti-slip lines on the battery cover 3 are used as the part in contact with the desktop, thereby playing a role in preventing slipping, and the anti-slip lines on the pressing part 44 play a role in preventing fingers from slipping.

[0038] Further, in order to facilitate the user to know the power state, the battery monomer 1 of the embodiment is provided with an indicator light 15, the indicator light 15 is electrically connected with the circuit board 12, and the position of the battery monomer 1 provided with the indicator light 15 is located outside the battery compartment 21 and the battery cover 3.

[0039] Further, in order to enable the battery monomer 1 to be inserted into the battery compartment 21 and the battery cover 3 in the correct orientation and not to be rotated during assembly, the inner cavity wall of the battery cover 3 and the battery compartment 21 of the embodiment is provided with a sliding strip 45, and the corresponding position of the side surface of the battery monomer 1 relative to the sliding strip 45 is provided with a sliding groove 46, the sliding strip 45 is embedded in the sliding groove 46, thereby playing a role in guiding and limiting.

[0040] The above are only preferred embodiments of the present application, and do not limit the patent range of the present application, and any equivalent structure or equivalent process transformation made by using the content of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection range of the present application.
