Because the charging head 2 of the power adapter is fixed by the charging seat lower shell 16, and part of the structure of the charging head 2 passes through the through hole 131, when the electric appliance to be charged is placed on the charging device 100, the charging head 2 can be directly inserted into the charging port of the electric appliance to be charged for charging.

Specifically, a Power adapter (Power adapter) is a Power supply conversion device of a small portable electronic device, and the working principle of the Power adapter is to convert commercial Power from alternating current input into direct current output, the Power adapter generally comprises an adapter body and a charging head 2, the adapter body and the charging head 2 are electrically connected through a wire or a connecting wire, and the adapter body is directly connected with the commercial Power through a plug and the like. The charging head 2 is fixed in the hollow cavity 12 through the charging base lower shell 16, and a part of the charging head 2 passes through the through hole 131, specifically, a part of the charging head 2 is fixed in the hollow cavity 12, and one end of the charging head for charging passes through the through hole 131 and is exposed out of the charging base upper shell 15, so that when an electric appliance to be charged, such as a vacuum cleaner, is carried on the charging device 100, the charging head 2 is directly inserted into a charging port of the vacuum cleaner.

As to the specific fixing manner of the charging head 2 and the charging-stand lower shell 16, optionally, as shown in fig. 2 and 3, the charging head 2 includes a charging terminal 21 and a terminal 22, the charging terminal 21 passes through the through hole 131, the terminal 22 includes a first end 221 and a second end 222, a flange 223 is disposed between the charging terminal 21 and the first end 221, the charging-stand upper shell 15 abuts against the flange 223, and the charging-stand lower shell 16 abuts against the second end 222, so as to clamp the terminal 22 in the hollow cavity 12. This can expose the charging terminal 21 outside the charging base top case 15, and the terminal 22 is located in the hollow cavity 12, so that the distance that the charging terminal 21 is exposed outside the charging base top case 15 is small. And the charging terminal 21 is easily erected on the charging-stand upper case 15. The terminal 22 is interposed between the charging-stand upper case 15 and the charging-stand lower case 16, which also facilitates the stable fixation of the charging head 2 within the hollow cavity 12. In order to ensure that the flange 223 is in good contact with the charging-stand upper case 15, the diameter of the through-hole 131 may be slightly larger than the diameter of the charging terminal 21 and smaller than the outer diameter of the flange 223.

For the fixing manner of the charging-stand upper shell 15 and the charging-stand lower shell 16, it can be considered to detachably connect the two components so as to install the components into the hollow cavity 12, for example, as shown in fig. 3 and 4, at least two lower shell mounting posts 163 are further provided on the charging-stand lower shell 16, at least two upper shell mounting posts 164 are further provided on the charging-stand upper shell 15, and the positions of the lower shell mounting posts 163 and the upper shell mounting posts 164 correspond to each other and are connected by a threaded fastener. Specifically, the projections of the lower shell mounting posts 163 and the upper shell mounting posts 164 on the lower shell 16 of the charging stand coincide, and at least two of the lower shell mounting posts 163 and at least two of the upper shell mounting posts 164 have screw holes inside, and the screw holes of at least two of the lower shell mounting posts 163 penetrate through the lower shell 16 of the charging stand. Thus, fasteners such as screws can be screwed into the threaded holes of the upper shell mounting post 164 and the lower shell mounting post 163 outside the charging base 1, and the charging base upper shell 15 and the charging base lower shell 16 can be detachably connected.

In addition, as shown in fig. 3, the charging base upper shell 15 and the charging base lower shell 16 can be connected by means of fastening, for example, a first fastening portion 165 is disposed on the charging base lower shell 16, a second fastening portion 166 is disposed on the charging base upper shell 15 at a position corresponding to the first fastening portion 165, when the charging base upper shell 15 is covered by the charging base lower shell 16, the first fastening portion 165 and the second fastening portion 166 are fastened with each other, so that the charging base upper shell 15 and the charging base lower shell 16 are more firmly fixed.

Further, as shown in fig. 4, alternatively, the lower case mounting post 163 is disposed at the side of the support portion 161, and a connection rib 167 is provided between the lower case mounting post 163 and the support portion 161. This can increase the coupling strength between the lower case mounting post 163 and the support 161. When the charging device 100 is dropped or the like, the charging-stand upper case 15 and the charging-stand lower case 16 are not likely to be dropped.

Further, fig. 5 is a cross-sectional view of a charging device according to a first embodiment of the present invention, as shown in fig. 2 and 5, a containing groove 13 is formed on an upper surface of the charging seat upper shell 15, and the through hole 131 is disposed on a groove wall of the containing groove 13. Specifically, the bottom of the accommodating groove 13 may be provided. The receiving groove 13 can be used for receiving a bottom of an electric appliance to be charged, such as a vacuum cleaner, and charging the electric appliance to be charged. The inner shape of the containing groove 13 can be matched with the lower shape of the electric appliance to be charged, the charging seat upper shell 15 shown in fig. 2 is hollow and is formed with a groove, the charging seat lower shell 16 covers the notch of the groove, thus, no seam appears in the range of the charging seat 1 which can be observed by people, and the appearance can be improved. Of course, the present invention is not limited to this, and the charging seat upper shell 15 and the charging seat lower shell 16 may have grooves therein, and the two grooves are opposite to each other to form the hollow cavity 12. As for the specific arrangement position of the charging head 2 on the groove wall of the accommodating groove 13, as shown in fig. 3, the charging head 2 of the charging head 2 may be arranged on the groove bottom wall of the accommodating groove 13, which corresponds to the case where the charging port of the electric appliance to be charged is arranged at the bottom of the electric appliance to be charged. Generally speaking, the position of the charging terminal 21 on the wall of the containing slot 13 corresponds to the position of the charging port 301 of the electric appliance to be charged, so as to ensure that the charging terminal 21 can be inserted into the charging port 301 when the electric appliance to be charged is contained in the containing slot 13.

In addition, as for the formation manner of the accommodation groove 13, corresponding to the case that the charging-stand upper case 15 and the charging-stand lower case 16 jointly enclose the hollow cavity 12, an end portion of the charging-stand upper case 15 away from the charging-stand lower case 16 may be recessed to form the accommodation groove 13.

In addition, generally, the outer contour of the electric appliance to be charged is irregular, so that the position of the center of gravity thereof is not necessarily located at the position of the geometric center thereof, and therefore, when the electric appliance to be charged is placed in the accommodating groove 13, there may be a case where the electric appliance to be charged is easily toppled over, and as shown in fig. 5, it may be considered that the height of a part of the wall of the accommodating groove 13 is relatively high, specifically, the wall of the accommodating groove 13 includes a first groove wall section 132 and a second groove wall section 133, and the height h1 of the first groove wall section 132 relative to the bottom of the accommodating groove 13 is greater than the height h2 of the second groove wall section 133 relative to the bottom of the accommodating groove 13, wherein the first groove wall section 132 corresponds to the direction. So arranged, first wall segment 132 can give better support to the electrical apparatus that waits to charge, prevents it and topples over. In addition, the height of the second wall section 133 relative to the bottom of the accommodating groove 13 is h2, so that the second wall section 133 can also support the electric appliance to be charged.

Further, the height h3 of the charging end 21 of the charging head 2 with respect to the bottom of the accommodating groove 13 is smaller than the height h2 of the second wall section 133 with respect to the bottom of the accommodating groove 13. If the height h3 of the charging end 21 of the charging head 2 relative to the bottom of the accommodating groove 13 is equal to the height h2 of the second wall portion 133 relative to the bottom of the accommodating groove 13, when the electric appliance to be charged is mounted on the accommodating groove 13, the rear side of the electric appliance to be charged is likely to collide with the charging end 21, and if h3 is smaller than h2, the situation can be avoided.

In addition, in the case that the electric appliance to be charged is provided with a handle, it is considered that the accommodating groove 13 also includes a portion capable of accommodating the handle, specifically, a handle accommodating groove 134 is formed in a manner that at least a portion of a groove wall of the first groove wall section 132 is partially recessed in a direction perpendicular to the accommodating groove 13, so as to accommodate the handle of the electric appliance to be charged.

In this embodiment, charging device includes charging seat epitheca, charging seat inferior valve and power adapter, and the charging seat epitheca encloses with the charging seat inferior valve and closes formation cavity, and the charging seat epitheca is equipped with a perforation, and power adapter is including the head that charges, and the head that charges passes through the charging seat inferior valve to be fixed in the cavity and the part passes the perforation.
