Detailed Description

The following detailed description of preferred embodiments of the application is made in connection with the accompanying drawings, which form a part hereof, and together with the description of the embodiments of the application, are used to explain the principles of the application and are not intended to limit the scope of the application.

In describing embodiments of the present invention, it should be noted that, unless explicitly stated and limited otherwise, the term "coupled" should be interpreted broadly, for example, as being fixedly coupled, as being detachably coupled, as being integrally coupled, as being mechanically coupled, as being electrically coupled, as being directly coupled, as being indirectly coupled via an intermediate medium. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

The terms "top," "bottom," "above … …," "below," and "on … …" are used throughout to describe relative positions with respect to components of the device, such as the relative positions of the top and bottom substrates inside the device. It will be appreciated that the devices are versatile, irrespective of their orientation in space.

As shown in fig. 1 and 2, an embodiment of the present invention provides a handheld vacuum cleaner, including: an air inlet pipeline, an upper cover body 1, an airflow generator 3 and a handheld part 4; an air inlet duct directs an air flow into the cyclonic separating assembly; the airflow generator 3 provides a suction force for sucking the airflow; the upper cover body 1 is provided with an upper cover 8 which can be movably connected; the upper cover 1 comprises a cyclonic separating assembly and a battery assembly 15 which partially surrounds the cyclonic separating assembly; the axis of the cyclone separating component is a first axis 12, the direction of the first axis 12 is defined as the height direction, and the upper cover 8 is arranged at the upper end of the handheld dust collector; the airflow generator 3 is arranged on top of the hand-held part 4. In the embodiment of the invention, the battery surrounds the outer side of the cyclone separator 5, which is favorable for the integrated design of the whole dust collector, and meanwhile, only the airflow generators 3 are reserved at the two ends of the handle, so that more space can be provided for the handle.

The vacuum cleaner cannot be reduced uniformly, and the vacuum cleaner is too small, and the corresponding hand-held part 4 is too small, which adversely affects the holding and operation, and is disadvantageous for the first time of use of the vacuum cleaner, so that the relative positional relationship between the battery assembly 15 and the hand-held part 4 needs to be defined. The positional relationship between the battery assembly 15 and the hand-held portion 4 in the embodiment of the present invention includes two types:

Along the direction of height, battery pack 15 is located the top of dirt bucket 7 at least partially, and battery pack bottom's lowest department is less than the top highest department of handheld portion 4, and battery pack 15 can be partly located dirt bucket 7, can reduce the height of dust catcher front end part, can also increase the capacity of dirt bucket 7, avoids too frequent clearance dirt bucket 7.

Along the direction of height, battery pack 15 is located the top of dirt bucket 7, and battery pack 15's bottom lowest is higher than the top highest of handheld portion 4, and compact design and high relation combine together, can make battery pack 15 and air current generator 3's relative position and house compact, have shortened the distance between the two, have saved the space of dust catcher effectively, have shortened the overall length of air current passageway, have obviously alleviateed the loss of air current passageway length to suction force, conveniently set up relatively great handheld portion 4 moreover, improve the comfort level that the dust catcher used.

The height direction defined by the first axis 12 is not necessarily the same as the actual vertical direction, and the comparison of the height and the direction is based on the direction of the first axis 12.

In addition, as shown in fig. 2, the axis of the air inlet pipe is a second axis 13, the direction of the second axis 13 is defined as front and rear, and the air inlet pipe is arranged in front of the hand-held cleaner; the hand-held part 4 is a handle, and the axis of the handle is a third axis 14. It should be noted that, the front-back direction of the second axis 13 is not necessarily the same as the actual horizontal direction, and the front-back comparison is only based on the direction of the second axis 13, and the first axis 12 and the second axis 13 are not necessarily perpendicular to each other, and the included angle may be smaller than 90 °, but not preferably parallel or nearly parallel. The first axis 12, the second axis 13, and the third axis 14 are virtual lines provided for convenience in explaining the positional relationship of the respective components of the embodiment of the present invention.

In use of embodiments of the invention, the user will typically grasp the handle and hold the wrist straight, adjusting the attitude of the cleaner by swinging the forearm, thus ensuring that the first axis 12 is parallel to the forearm. However, when the wrist is straightened, the direction of the third axis 14 is not perpendicular to the second axis 13 when the palm naturally holds the handle, so in the embodiment of the invention, the included angle between the second axis 13 and the third axis 14 is 70 ° -80 °, and the top of the handle is closer to the first axis 12 than the bottom, so that when the wrist is straightened, the air inlet pipeline can be approximately parallel to the forearm, and a user can operate the cleaner without obviously bending the wrist, thereby improving the comfort and the convenience of operation of the embodiment of the invention.

When the embodiments of the present invention are not in use, they will typically rest on a surface, such as a table, shelf or car, but such surfaces are not necessarily horizontally disposed, likely due to the inclination of the surface, they will slide on the surface under the force of gravity or other external forces, and likely will break from the surface. In order to prevent the occurrence of the above situation, in the embodiment of the invention, the bottom end surface of the handle is provided with an anti-slip surface with a plane acting surface; the bottom surface of the cyclone separation assembly is coplanar with the anti-slip surface, and the anti-slip surface on the end surface of the bottom of the handle can prevent sliding to a certain extent even if the embodiment of the invention is placed on the inclined surface, so that the embodiment of the invention can be prevented from sliding and breaking, and the coplanar bottom surface can be relatively stably placed on a certain plane.

As shown in fig. 2, in the embodiment of the present invention, the first axis 12, the second axis 13 and the third axis 14 may be different-plane straight lines or coplanar straight lines, but in consideration of processing difficulty and aesthetic degree, in the embodiment of the present invention, the first axis 12, the second axis 13 and the third axis 14 are coplanar and form a first symmetry plane, and it should be noted that the first symmetry plane is a virtual plane.

In order to reduce the volume of the embodiment of the present invention and make the structure more compact, as shown in fig. 5, the embodiment of the present invention partially surrounds the battery assembly 15 outside the cyclone separation assembly, specifically, the battery assembly 15 includes at least 2 battery units 16 and a battery cavity, the cross section of the battery cavity is fan-shaped, and the axis coincides with the first axis 12, and considering that the main body of the cyclone separation assembly is a revolution body, the fan-shaped battery cavity can fully utilize the space around the filter 5, so that the structure of the embodiment of the present invention is more compact. The opening of the battery cavity faces the airflow generator 3, and the air outlet of the cyclone separation assembly is communicated with the airflow generator 3 through the opening of the battery cavity, so that the airflow passage between the cyclone separation assembly and the airflow generator 3 is as short as possible, the loss of suction force caused by the overlong airflow passage is obviously relieved, and finally, the embodiment of the invention has larger suction force, and the working efficiency of the embodiment of the invention is improved.

Considering that the battery unit 16 includes electronic components, in the embodiment of the invention, the battery unit 16 is mounted in the battery cavity through the battery frame, and the mounting bracket can effectively protect the battery unit 16 from damaging the battery unit 16 by accidental vibration, and meanwhile, a certain distance between adjacent battery units 16 can be reserved for heat dissipation, so that the battery assembly 15 is prevented from being locally overheated. From the viewpoint of facilitating mass production of the embodiment of the present invention, each component is preferably designed symmetrically or normalized, so, as shown in fig. 3, in the embodiment of the present invention, the battery units 16 are symmetrically arranged about the first symmetry plane, and the embodiment of the present invention uses 8 battery units 16, which are illustratively divided into two groups of 4, two groups of 4 are symmetrical about the first symmetry plane, and the 4 battery units 16 in each group are arranged at equal central angles in the fan-shaped battery cavity.

If heat is dissipated by heat transfer only between the spaces between the battery cells 16 and the outside, the heat dissipation efficiency is extremely low, and there is a possibility that the battery assembly 15 as a whole may overheat. Therefore, in the embodiment of the present invention, the upper cover 8 is provided with a fan-shaped heat dissipation portion, the axis of the heat dissipation portion coincides with the first axis 12, the opening direction coincides with the battery cavity, and the projection of the heat dissipation portion and the battery cavity on a plane perpendicular to the first axis 12 at least partially coincides. The shape of the heat dissipation portion is set as described above, so that the heat dissipation portion is substantially the same as the shape of the battery assembly 15, and heat generated by the battery assembly 15 can be timely transferred to the outside through the heat dissipation portion, and heat dissipation can be effectively performed on the battery assembly 15. The heat sink may take a variety of forms, and may be, for example, a metal or alloy plate or sheet having a small specific heat capacity, or may be provided with a cold fluid circulation, etc.

In order to reduce the production cost and the processing difficulty of the embodiment of the invention on the premise of not obviously influencing the heat dissipation effect. In the embodiment of the invention, the fan-shaped surface of the heat dissipation part is uniformly provided with the heat dissipation holes 10, external cold air can enter the shell of the embodiment of the invention through the heat dissipation holes 10, and internal hot air can also flow out of the shell of the embodiment of the invention through the heat dissipation holes 10, so that certain cold and hot air convection can be formed, and the heat dissipation of the battery assembly 15 can be effectively carried out.

As shown in fig. 1, in the embodiment of the present invention, the cyclone separation assembly includes a filter 5 and a dust tub 7 disposed under the filter 5, and the dust tub 7 is used for collecting dust or foreign matters separated from the filter 5 and can be removed from under the embodiment of the present invention to clean dust in the dust tub 7. Accordingly, the battery assembly 15 partially surrounds the filter 5.

In practical use of the embodiment of the present invention, dust or foreign matter may clog the filter assembly 6 in the filter 5 with the use time being prolonged, so in the embodiment of the present invention, the movably connected upper cover 8 is mainly used to remove the filter assembly 6, and clean or replace the filter assembly 6. Specifically, as shown in fig. 5, the upper cover 8 can be in tight sealing contact with the top of the filter 5, preventing the air flow from directly entering from the junction of the upper cover 8 and the filter 5, and the filter assembly 6 of the filter 5 can be removed from the filter 5 when the upper cover 8 is opened or removed. Illustratively, the upper cover 8 is hinged to the upper cover body 1, and the filter pad can be taken out by opening the upper cover 8, or the upper cover 8 is in snap connection with the upper cover body 1, and the filter pad can be taken out after the upper cover 8 is detached directly by the upper cover 8.

In order to facilitate the operation of the embodiment of the present invention, as shown in fig. 3, in the embodiment of the present invention, the rear end of the upper cover 8 is provided with the operation button 11, when the embodiment of the present invention is used, a user holds the handle, the operation button 11 is located in the range of the upper end of the handle, and the user can press the operation button 11 through the thumb, so that the embodiment of the present invention realizes one-hand operation, and is simple and convenient.

As shown in fig. 4, in the embodiment of the present invention, the rear end side surface of the airflow generator 3 is provided with an exhaust structure conformal to the rear end side surface of the airflow generator 3, so that good and smooth airflow same path can be ensured, and the embodiment of the present invention has good and attractive shape.

In addition to having a good appearance, the handheld vacuum cleaner needs to have a good suction force, but in order to reduce the volume of the handheld vacuum cleaner, a motor with smaller power is preferably selected. Illustratively, in the embodiment of the present invention, the plane of the strip-shaped hole 9 is low at the front and high at the rear, and is tilted upwards, so that the high-speed air flow discharged from the strip-shaped hole 9 can be prevented from blowing to the hand of the user to a certain extent, and abnormal feeling caused by the user can be avoided.

The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention.
