DETAILED DESCRIPTION

[0024] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] See also Figure 1-4 The utility model provides a handheld vacuum cleaner, comprising a main body 1, a control device 2 fixedly arranged on the main body 1, and a movable device 3 movably arranged in the main body 1, wherein the main body 1 comprises a dust collecting device 10 arranged in an internal cavity thereof and a cyclone system 11 arranged in the dust collecting device 10;

[0026] The control device 2 is arranged on the main body 1 and is used to control the movable device 3 to move from the first position to the second position. The movable device 3 includes a suction device 30 and a filtering device 31. The outer ring of the filtering device 31 is provided with a metal mesh 100. The inner cavity of the main body 1 is fixedly provided with a scraper 101 corresponding to the position of the metal mesh 100, and the scraper 101 is close to the metal mesh 100.

[0027] The main body 1 includes a fixing ring 200 fixedly arranged inside the main body 1 and a socket 201 arranged on the fixing ring 200. The suction device 30 is fixedly provided with a plug 202 used in conjunction with the socket 201. When the movable device 3 is located at the first position, the suction device 30 is pressed against the fixing ring 200, and the plug 202 is inserted into the socket 201. At this time, the suction device 30 is powered on.

[0028] When the movable device 3 moves from the first position to the second position, the suction device 30 moves, and the latch 202 leaves the socket 201 . At this time, the suction device 30 is powered off, and the metal mesh 100 moves and is scraped by the scraper 101 .

[0029] In the above structure, the control device controls the movable device to move up and down. When the movable device moves upward, the socket is disconnected from the plug, the suction device is powered off and no longer operates, the metal mesh is scraped by the scraper, and the dust and garbage attached to the metal mesh are cleaned off the metal mesh by the scraper and fall into the dust collecting device. When the movable device moves downward, the fixed ring fixes the movable device and no longer moves downward, the socket is connected to the plug, and the suction device is powered on and operates. As a whole, the suction device is powered off during the cleaning process of the metal mesh, thereby preventing dust or garbage from being sucked into the filter device due to the operation of the suction device during the cleaning process, thereby improving the service life of the filter device.

[0030] Specifically, a base cover 12 is provided at the bottom of the main body 1, and a button 13 cooperating with the base cover 12 is provided on one side of the main body adjacent to the base cover 12. The base cover switch can facilitate cleaning of dust sucked into the handheld vacuum cleaner.

[0031] Specifically, a filter net 310 is arranged inside the filter device 31, and the filter net 310 is a HEPA filter net. The advantage of using the HEPA filter net is that the HEPA filter net is more efficient, has a high purification efficiency and has an antibacterial effect.

[0032] Specifically, the main body 1 is connected to the control device 2 via a reset spring 400. The reset of the reset spring can prevent the control device from being unable to return to its original position when the upward pulling force is no longer applied. The use of the reset spring has the advantages of high stability, space saving and automatic reset.

[0033] Specifically, the control device 2 includes a lifting cover 14 arranged on the main body 1 and a handle 15 arranged on the lifting cover 14. The lifting cover 14 is recessed with a handle groove 16 corresponding to the position of the handle and having the same size as the handle. The handle is fitly placed in the handle groove, so that the structure is beautiful and the visual effect is not abrupt.

[0034] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
