DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 5In an embodiment of the utility model, a multifunctional portable emergency power supply includes a power supply body 10, one end of the body 10 is provided with an emergency component 20, and the other end thereof is provided with a blowing component 30, the emergency component 20 is provided with an energy storage battery 21 and an output female socket 22 electrically connected to each other, the energy storage battery 21 is used to store electrical energy, and the output female socket 22 is used to electrically connect to an external car, so as to perform emergency start of the external car; the blowing component 30 is provided with a high-speed fan 31, and the high-speed fan 31 is electrically connected to the energy storage battery 21, so as to provide operating power for the high-speed fan 31, so that the high-speed fan 31 is operated, a strong airflow is generated, and a strong blowing effect is formed, so that external dust or falling snow and other debris can be blown and cleaned.

[0034] Specifically, the existing emergency power supply is usually combined with the lighting function, but its function is still relatively simple and not convenient for users to use. Therefore, by respectively setting the emergency component 20 and the blowing component 30 at both ends of the power supply body 10, it is possible to use the energy storage battery 21 and the output socket 22 to perform emergency start operation on the external car, and in daily use, the high-speed airflow blown by the high-speed fan 31 of the blowing component 30 can be used to clean up external dust, leaves, fallen snow and other debris, thereby improving the quality of life and improving portability.

[0035] Secondly, the energy storage battery 21 preferably adopts a power battery, so that it can provide a large current output. In addition, multiple batteries can be used to form a battery pack, thereby forming a 12V energy storage battery 21, so that it can directly start the car in an emergency. Similarly, the high-speed fan 31 also preferably adopts a 12V high-speed motor, so that it can output a high-speed airflow. For example, a high-speed motor with a 12V voltage can reach a speed of 110,000 to 150,000, so that the high-speed fan 31 can generate a very high-speed airflow to blow and clean external debris.

[0036] like Figure 1 and Figure 3 As shown, preferably, the emergency component 20 is further provided with a charging interface 23, the charging interface 23 is electrically connected to the energy storage battery 21, and is used to connect the energy storage battery 21 to external power, thereby charging the energy storage battery 21. The emergency component 20 is also provided with an output interface 24, the output interface 24 is electrically connected to the energy storage battery 21, and is used to provide output power to an external device, thereby powering the external device.

[0037] Specifically, the charging interface 23 can be set as a USB Type-C standard interface, so as to facilitate the replenishment of power for the emergency power supply. In addition, according to the characteristics of the USB Type-C standard interface, it can also be set to be able to supply power to the outside, so that it can not only charge the energy storage battery 21, but also output power to external devices through the Type-C interface. Secondly, the output interface 24 can be set as a USB Type-A standard interface, so that it can power a wide range of other electronic devices.

[0038] like Figure 2 and Figure 3 As shown, preferably, the emergency component 20 is also provided with a control circuit board 25 and a switch button 26. The control circuit board 25 is installed inside the main body 10 and is electrically connected to the switch button 26, the energy storage battery 21, the charging interface 23 and the output interface 24 respectively. The switch button 26 is used to control the opening and closing of the output interface 24.

[0039] Specifically, since the energy storage battery 21 uses a 12V voltage for output, and the USB Type-A standard interface needs to provide a 5V voltage output, a control circuit board 25 is also required to be provided so that the voltage of the energy storage battery 21 can be converted into a 5V voltage output after passing through the control circuit board 25. Because the control circuit board 25 also has a voltage conversion function, if it is kept running continuously, it is easy to cause a waste of electric energy, or even exhaust the internal electric energy of the energy storage battery 21, resulting in damage to the energy storage battery 21. Therefore, a switch button 26 can be provided to turn the control circuit board 25 on or off. At the same time, a control chip can also be provided on the control circuit board 25, and the control chip can be used to achieve a timed shutdown of the control circuit board 25, that is, after detecting that the USB Type-A standard interface has not been used to output electric energy for a certain period of time, the control circuit board 25 is automatically shut down. When it needs to be used again next time, the switch button 26 can be pressed again to turn on the control circuit board 25 again.

[0040] Secondly, if the USB Type-C standard interface of the charging interface 23 is also set to provide output power to the outside, the charging interface 23 can also be included in the management scope of the control circuit board 25, so that it can also be automatically closed, or opened or closed by the switch button 26.

[0041] In addition, since the output socket 22 of the emergency component 20 is directly connected to the 12V power output port of the energy storage battery 21 without the need for voltage conversion, there will be no power loss. Therefore, the output socket 22 does not need to be connected to the control circuit board 25, but can be directly electrically connected to the power output port of the energy storage battery 21, so that the output socket 22 can provide better output performance, thereby providing the external car with the current and voltage required for emergency starting.

[0042] like Figure 4 and Figure 5 As shown, preferably, the blowing assembly 30 is further provided with a gear button 32 , and the gear button 32 is electrically connected to the energy storage battery 21 and the high-speed fan 31 , respectively, and controls the switch and the operating gear of the high-speed fan 31 .

[0043] Specifically, in order to make the high-speed fan 31 more widely used, a gear button 32 can be provided to control the operating gear of the high-speed fan 31, for example, the gear button 32 can be used to cycle between the off gear, the low speed gear, the medium speed gear and the full speed gear. In addition, the gear button 32 and the high-speed fan 31 can also be electrically connected to the control circuit board 25, respectively, so as to achieve corresponding electrical connection and control.

[0044] like Figure 2 As shown, preferably, the main body 10 is further provided with a gripping handle 11 , and the emergency component 20 is installed inside the gripping handle 11 , and the shape of the gripping handle 11 matches the shape of the energy storage battery 21 .

[0045] Specifically, in order to further reduce the size of the emergency power supply and improve its portability, it is preferred that the shape of the gripping handle 11 is set to adapt to the shape of the energy storage battery 21. For example, if the energy storage battery 21 is a square battery, the gripping handle 11 also adopts a square shell, so that the relative fit with the energy storage battery 21 is tighter, thereby reducing the volume of the gripping handle 11. For example, if the energy storage battery 21 is a cylindrical battery, the gripping handle 11 can also adopt a round shell, so that the energy storage battery 21 and the round shell are relatively tight, and the volume of the gripping handle 11 is reduced.

[0046] like Figures 2 to 4 As shown, preferably, the main body 10 is also provided with a blowing shell 12, the blowing shell 12 is fixedly connected to one end of the holding handle 11, and forms a cylindrical air flow channel with an internal hollow interior and openings at both ends, and the high-speed fan 31 is installed in the cylindrical air flow channel of the blowing shell 12, so that air is blown from one end of the blowing shell 12 to the other end at high speed, forming a high-speed airflow.

[0047] Specifically, one end of the gripping handle 11 may be installed with an output socket 22, and the other end thereof may be fixedly connected with a blowing assembly 30, that is, the blowing assembly 30 and the output socket 22 are respectively arranged at the two ends of the gripping handle 11. This can reduce the volume of the emergency power supply, so that the two ends have different functions, and it is also convenient to use. In addition, the output socket 22 preferably adopts a universal EC5 interface, thereby improving the versatility of the emergency power supply, so that it can use the power connection clip of the EC5 interface to clamp the car power connection column, so as to perform emergency start.

[0048] like Figure 4 and Figure 5 As shown, preferably, the blowing assembly 30 is also provided with an air inlet tube 33 and a blowing nozzle 35. The air inlet tube 33 is installed at the air inlet end of the blowing shell 12 to form an air flow inlet. One end of the air inlet tube 33 abuts against the high-speed fan 31, and the other end is provided with a plurality of air inlet holes 34, so that air enters the high-speed fan 31 from the air inlet holes 34; the blowing nozzle 35 is set to a funnel shape with a diameter at one end larger than the diameter at the other end, and the end with a larger diameter can be detachably installed on the air outlet end of the blowing shell 12, and the end with a smaller diameter forms an air flow outlet for air to be blown out at high speed.

[0049] Specifically, since the operation of the blowing assembly 30 can generate high-speed airflow, the air also flows into the air inlet tube 33 at high speed from one end of the air inlet tube 33, so a corresponding mesh structure can be set at one end of the air inlet of the air inlet tube 33, that is, a plurality of air inlet holes 34 are formed, so that air can enter normally through the air inlet holes 34, while preventing other objects from entering the air inlet tube 33, thereby preventing foreign objects from damaging the high-speed fan 31.

[0050] Secondly, the blowing nozzle 35 can be installed on the blowing housing 12 by snap-fit ​​connection, so that it can be disassembled or replaced. For example, a variety of other shapes of blowing nozzles 35 can be provided so that they can be replaced and installed on the blowing housing 12, so as to achieve different blowing functions. For example, the blowing nozzle 35 with an air inlet diameter smaller than the air outlet diameter can be provided. After it is installed on the blowing housing 12, the high-speed airflow blown out by the high-speed fan 31 can be decelerated, making the airflow relatively gentle, so that it can be used to dry the user's hair, etc.

[0051] like Figure 3 and Figure 4As shown, preferably, the blowing assembly 30 is further provided with an air guide 36, which is installed inside the blowing housing 12, one end of which abuts against the high-speed fan 31, and the other end of which extends to the air outlet of the blowing housing 12; the air guide 36 is used to guide the airflow blown by the high-speed fan 31 to flow to the air outlet of the blowing housing 12 to avoid collision with the internal structure of the blowing housing 12. The blowing assembly 30 is also provided with a protective net 37, which is installed at the air outlet of the blowing housing 12 to prevent foreign matter from entering the blowing housing 12 or the air guide 36.

[0052] Specifically, since the inner wall of the air blowing shell 12 is provided with some reinforcing ribs, if the high-speed airflow flows directly inside the air blowing shell 12, it is easy for the high-speed airflow to hit the reinforcing ribs, resulting in a large noise, and also affecting the flow speed of the high-speed airflow. Therefore, an air guide tube 36 with a smooth inner wall can be provided to guide the high-speed airflow so that it can be blown out at a high speed. In addition, since the air blowing nozzle 35 can be replaced, a protective net 37 can be provided at the air outlet end of the air blowing shell 12 to prevent foreign matter from entering the air guide tube 36 and affecting the normal operation of the air blowing assembly 30.

[0053] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
