The supporting surface 6 is provided with an anti-skid layer, so that the stability of the supporting surface 6 for supporting the handheld dust collector can be further improved. Considering that the length of the cyclonic separating apparatus 1 is relatively long, the length of the support surface 6 in the direction of the first axis 7 is no less than 1/2 of the length of the main body portion in the direction of the first axis 7, so that the projection of the centre of gravity of the main body portion onto the plane of the support surface 6 does not fall outside the range of the support surface 6, preventing the main body portion from being influenced by gravity and unable to be stably supported by the support surface 6.

Consider the utility model discloses power supply portion adopts rechargeable battery usually, consequently need set up corresponding charging connection port, and is concrete, as shown in fig. 4, in the embodiment of the utility model provides an, power supply portion shell 4's second end is equipped with the face of charging of perpendicular to primary axis 7, is equipped with the power supply connecting hole that is on a parallel with primary axis 7 on the face of charging. When the hand-held cleaner is placed on the storage rack for charging, the opening position of the charging hole 14 faces the position of the floor.

Because main part and power supply portion shell 4 are connected with the form of holding portion 3 relatively all with the cantilever beam, the junction is very easy fracture, in order to improve the stability of structure, the embodiment of the utility model provides an in, be equipped with supporting part 5 between power supply portion shell 4 and the main part, can make main part, supporting part 5, power supply portion shell 4 and hold portion 3 form the structure of similar frame type through supporting part 5 to improve overall structure's stability. The axis of the supporting part 5 is a third axis 9, the included angle between the third axis 9 and the first axis 7 is larger than or equal to 78 degrees and smaller than 80 degrees, the inclined directions of the third axis 9 and the second axis 8 relative to the first axis 7 are the same, when the handle is held, object holding spaces of four fingers except the thumb are arranged between the supporting part 5 and the handle, the thicknesses of the four fingers can be approximately regarded as the same, therefore, the third axis 9 and the second axis 8 are approximately parallel, and the effective space of the holding space between the supporting part 5 and the handle can be made as large as possible. In order to make the overall structure of the hand-held cleaner more stable and to make the actual space between the support portion 5 and the grip portion 3 as large as possible, the projection of the support portion 5 on the first reference plane at least partially coincides with the projection of the cyclonic separating assembly 1 on the first reference plane.

To sum up, the embodiment of the present invention provides a handheld vacuum cleaner, the present invention provides an operating portion 2 and a holding portion 3 respectively disposed at two sides of a main body portion, so as to avoid the accidental touch of fingers on the operating portion 2 when holding the holding portion 3, and reduce the probability of carrying out the misoperation on the operating portion 2; the utility model can realize the stable support of the main body part only through the supporting surface 6 by arranging the supporting surface 6 of the power supply part shell 4 under the condition that the holding part 3 is approximately parallel to the supporting part 5; the embodiment of the utility model provides a through the setting to the relative position of primary shaft 7, secondary shaft 8, third axis 9 and the projection position relation setting of each part, can enough increase the bearing surface 6 to holistic support stability, can increase again as far as possible and hold the space between portion 3 and the supporting part 5, and then make the space of holding of hand strengthen, increase the travelling comfort.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
