DETAILED DESCRIPTION

[0039] The present invention is further described in detail below with reference to the embodiments:

[0040] Example 1

[0041] like Figure 1 、 Figure 5 and Figure 6 As shown, the utility model provides a multifunctional automobile emergency starting power supply, including a shell 1; a handle strap 2 is fixedly connected to the top of the shell 1, an upper shell 12 and a lower shell 13 are fixedly connected to the interior of the shell 1, a display panel 7 is fixedly connected to the outer wall of the upper shell 12, a control button 8 is fixedly connected to the front end of the display panel 7, a main control board 15 is fixedly connected to the rear end of the display panel 7, a left cover 4 is fixedly connected to one side of the shell 1, and a right cover 14 is fixedly connected to the side of the shell 1 away from the left cover 4, and a dust collection component is provided inside the shell 1, which is used to clean debris in the car.

[0042] Since the car emergency starting power supply needs to have functions such as vacuum cleaner and exhaust, however, the air inlet and air outlet of the product cavity are set on the same side at this stage, both are perpendicular to the direction of rotation of the fan blades. The air sucked in from the air inlet by the rotation of the fan blades inside the cavity forms an air flow. The air flow is accelerated by the fan blades and is thrown out by centrifugal force. The internal space of the cavity is small, and the air flow bounces back after passing through the inner wall of the cavity, and cannot form an effective air spiral to guide the air out of the air outlet. The air flow collides with the newly inhaled air flow and the air flow to be thrown out inside the cavity, resulting in loss of wind power, reduced air intake speed, and reduced dust collection effect.

[0043] In this embodiment, the function of the device is selected by the control button 8, and the dust collection component is started to clean the dust and snack crumbs that the driver and passengers accidentally bring into the car when getting on and off the car, so as to keep the car clean.

[0044] like Figure 5 and Figure 6 As shown, preferably, the dust collection component includes a No. 1 fan 19 fixedly connected to the inner wall of the lower shell 13, and the air inlet end of the No. 1 fan 19 is fixedly connected to the fan cover 26, the fan cover 26 is a hollow channel structure, and the hollow channel structure of the fan cover 26 is provided with an air inlet 25 of the dust collection component at one end, and the fan cover 26 is connected to the air inlet 25 in an arc transition connection, and the opening size of the port where the fan cover 26 is fixedly connected to the No. 1 fan 19 is larger than the opening size of the air inlet 25 at the other end, and the outer wall of the No. 1 fan 19 is fixedly connected to the middle bracket 18, and the side of the middle bracket 18 is provided with an air outlet 20, and the air outlet 20 is set at an angle of 90 degrees to the air inlet 25.

[0045] In this embodiment, the cavity formed by the fan cover 26 and the middle bracket 18 is divided into two parts. The air inlet 25 of the lower part is in the shape of a trumpet, and the opening size at the top is larger than the opening size at the bottom. When the blades of the No. 1 fan 19 rotate at high speed, a negative pressure state can be formed for the external air, thereby increasing the power of inhaling air. The upper part is used to accommodate the air flow that is thrown out. After being blocked by the blades of the No. 1 fan 19, the recoil air flow will not directly collide with the air flow inhaled from the outside, and there will be no power reduction in the dust collection function. After being squeezed by the high-speed air flow, the air in the upper part is discharged from the air outlet 20. The air inlet 25 and the air outlet 20 are set at a vertical angle of ninety degrees. The air flow in the upper part of the cavity is accelerated by the fan blades and thrown out by centrifugal force, resulting in a better air outlet effect.

[0046] Example 2

[0047] like Figure 6-Figure 9 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the outer wall of the air inlet 25 is rotatably connected with a rotary joint 23, and the rotary joint 23 is installed in the No. 1 limit groove 24 in the lower shell 13. The No. 1 limit groove 24 is provided with a No. 2 limit groove 27 on the side close to the outer shell 1. The No. 1 limit groove 24, the No. 2 limit groove 27, the rotary joint 23, and the air inlet 25 are an axial concentric structure, and are connected to the No. 1 adapter 9 through the axial concentric structure. The outer wall of the No. 1 adapter 9 is fixedly connected to the limit block 22, and the limit block 22 is rotatably connected to the rotary joint 23.

[0048] Because the soft tube needs to be connected during the process of dust collection, however, the common adapter buckle structure in the market may not have enough interference amount, and the adapter may be twisted out of the buckle position due to the torsion generated by the rotation of the connected soft tube, causing the adapter to slide out of the gap of the buckle, resulting in functional failure of the product. The adapter needs to be inserted back to continue use, and dust may fall during this process, affecting the cleaning effect.

[0049] In this embodiment, an opening is provided at the bottom of the lower shell 13, which has the same shape as the first limiting groove 24 provided on the outside of the shell 1, and the rotary joint 23 can be inserted into the inside. It is used to connect the outside of the equipment and the first fan 19, wherein the bottom of the fan cover 26 is tightly connected with the rotary joint 23, and the first adapter 9 can also be inserted into the inside of the rotary joint 23. The air outside the equipment is sucked through the first adapter 9, which is embedded in the bottom of the lower shell 13 in the form of a rotary buckle. It should be noted that when the first adapter 9 is inserted, the limiting block 22 at the top of the first adapter 9 is aligned with the first limiting groove 24 and is inserted in a flush manner. The two can rotate relative to each other. When the conventional first adapter 9 is matched, the rotation of the first adapter 9 can further drive the rotary joint 23 to rotate until the gap is completely covered by the shell 1, greatly avoiding the phenomenon of accidental loosening and sliding out of the adapter during use, and increasing the stability of the structure.

[0050] Further, the limiting block 22 can drive the rotary joint 23 to rotate in reverse along the central axis of the first adapter 9. The central axis rotates in reverse in two gears. The first gear is locked by clamping the first adapter 9 and the rotary joint 23. When the first adapter 9 is rotated in the same direction again, the rotary joint 23 is locked in the second gear by the limiting block 22 in the first limiting groove 24 in the lower shell 13. The reverse rotation can be unlocked and separated from the first adapter 9 in steps. The second gear can be completely covered by the edge of the second limiting groove 27 on one side of the shell 1 to prevent the first adapter 9 from sliding out.

[0051] As shown in Figure 2 , Figure 3 and Figure 4 , preferably, the first adapter 9 and the connection position of the shell 1 are inserted with the air outlet dust plug 3, one side of the left cover 4 is inserted with the plug seal 5, one side of the left cover 4 is provided with the air charging adapter outlet 6, the air charging adapter outlet 6 is rotatably connected with the air charging adapter 16, the air charging adapter 16 is fixedly connected with the pressure air guide pipe 17 away from the left cover 4, one end of the pressure air guide pipe 17 is fixedly connected with the second fan 21, one side of the right cover 14 is inserted with the charge-discharge interface dust plug 10, and one side of the right cover 14 is fixedly connected with the soft light cover 11.

[0052] In this embodiment, the plug sealing plug 5 on the surface of the left cover 4 and the charge and discharge interface dust plug 10 on the surface of the right cover 14 effectively prevent dust from entering the interior of the device, thereby extending the service life of the device. By opening both, the function of powering the electronic device can be realized.

[0053] The working principle of the multifunctional automobile emergency starting power supply is described in detail below.

[0054] like Figures 1-9 As shown, first press the control button 8 according to the desired function. When it is necessary to clean the dust accidentally brought into the car by the driver and passengers getting on and off the car, and the food crumbs scattered by the driver and passengers when eating in the car, and keep the car clean, an opening is provided at the bottom of the lower shell 13, which has the same shape and contour as the No. 1 limit groove 24 opened on the outside of the shell 1, and a rotary joint 23 can be installed inside to connect the outside of the equipment and the No. 1 fan 19, wherein the bottom of the fan cover 26 is tightly connected to the rotary joint 23, and the No. 1 adapter 9 can also be inserted into the inside of the rotary joint 23 to absorb the air outside the equipment through the No. 1 adapter 9. The No. 1 adapter 9 is embedded in the bottom of the lower shell 13 in the form of a rotating buckle. It should be noted that when the No. 1 adapter 9 is inserted, the limit block 22 at its top is aligned with the No. 1 limit groove 24 and inserted flush. Structurally, the two can rotate relative to each other, unlike the conventional No. 1 adapter 9. By rotating the No. 1 adapter 9, it can be further The rotary joint 23 is driven to rotate step by step until the shell 1 completely folds the gap, which greatly avoids the phenomenon of the adapter loosening and sliding out during use, and increases the stability of the structure. The cavity formed by the fan cover 26 and the middle bracket 18 is divided into two parts. The air inlet 25 of the lower part is in the shape of a trumpet, and the opening size at the top is larger than the opening size at the bottom. When the fan blades of the No. 1 fan 19 rotate at high speed, a negative pressure state can be formed for the external air, thereby increasing the power of the air intake. The upper part is used to accommodate the air flow being thrown out. After being blocked by the fan blades of the No. 1 fan 19, the backwash air flow will not directly collide with the air flow inhaled from the outside, and there will be no power reduction in the dust collection function. After the air in the upper part is squeezed by the high-speed air flow, it is discharged from the air outlet 20. The air inlet 25 and the air outlet 20 are arranged at a vertical angle of 90 degrees. The air in the upper part of the cavity is accelerated by the fan blades and thrown out by centrifugal force, resulting in a better air outlet effect.

[0055] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
