Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a handheld vacuum cleaner. Background Art

[0002] With the development of science and technology, people's quality of life is constantly improving, consumer income continues to grow, especially the rapid growth of residents' income levels in large and medium-sized cities, and residents' living conditions are constantly improving. There are more and more duplex houses and large-area houses, and residents' demand for vacuum cleaners is getting stronger and stronger. However, in some relatively small environments, the large size of vacuum cleaners will cause inconvenience in cleaning, so people invented handheld vacuum cleaners. Handheld vacuum cleaners are small in size, very convenient to carry and use, and can clean some places that are inconvenient to clean with vacuum cleaners, such as cleaning the interior of vehicles. However, people found in the process of using handheld vacuum cleaners that after the vacuum cleaner sucks in dust and dirt, some of the dust and dirt will stick to the filter, which is very inconvenient to clean.

[0003] Based on the above reasons, it is necessary to improve the existing technology. Utility Model Content

[0014] Figure 2 It is a schematic diagram of the explosion structure of the utility model.

[0015] Figure 3 It is a schematic diagram of the cross-sectional structure of the utility model.

[0016] In the figure: 1 is the body, 2 is the dust cup, 3 is the fan, 4 is the filter, 5 is the cyclone system, 6 is the hanging bar, 7 is the connecting rod, 10 is the handle, 20 is the button seat, 21 is the button, 22 is the cup cover, 50 is the filter screen, 70 is the return spring, 71 is the guide strip, 100 is the filter hepa, and 200 is the dust suction duct. DETAILED DESCRIPTION

[0017] 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.

[0018] See also Figure 1-3 The utility model provides a handheld vacuum cleaner, comprising a body 1, a dust cup 2 arranged at the lower end of the body 1, a fan 3 fixedly arranged in the inner cavity of the body 1, a filter 4 arranged around the outside of the fan 3, and a cyclone system 5 fixedly arranged in the inner cavity of the dust cup 2 and connected to the fan 3 through a filter hepa 100, a dust suction pipe 200 is arranged at one end of the dust cup 2, a filter screen 50 is arranged on the outer ring of the cyclone system 5, a button seat 20 is fixedly arranged at one end of the dust cup 2, a button 21 is movably arranged on the button seat 20, a hanging strip 6 is arranged around the upper end of the filter screen 50, the hanging strip 6 is close to the filter screen 50, the hanging strip 6 is connected to the button 21 through a connecting rod 7, and a reset spring 70 is arranged in the inner cavity of the button seat 20.

[0019] In the above structure, when the filter needs to be cleaned, the button is slid downward, the hanging bar moves downward under the force of sliding downward, and the reset spring moves downward under the force, thereby deforming; when the button moves to the bottom, the hanging bar also moves to the bottom of the filter, thereby cleaning the filter; when the button is released, the reset spring is no longer subjected to the downward deformation force, thereby releasing the accumulated elastic force upward, and the button is subjected to the upward force of the reset spring, thereby driving the hanging bar to move upward together, thereby achieving the effect of automatic reset. The filter can be cleaned without removing the dust cup, thereby saving time and increasing the service life of the filter.

[0020] Specifically, a handle 10 is fixedly provided on the upper end of the body 1, and the handle can provide a better grip for the user, thereby saving effort in using the handheld vacuum cleaner.

[0021] Specifically, a cup cover 22 is movably provided at the bottom of the dust cup 2, and the cup cover can be directly opened at the bottom of the dust cup, eliminating the step of disassembling the dust cup for cleaning the dust in the dust cup, thereby saving time for cleaning the dust cup.

[0022] Specifically, a guide bar 71 is provided inside the return spring 70, and the guide bar can prevent the return spring from being offset and thus losing the return function.

[0023] 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.
