Electric vacuum cleaner

Abstract

Disclosed is a dust collector, comprising a dust collector body, a flexible hose and a floorboard sucker. The flexible hose comprises a first connecting part connected with a suction mouth, a second connecting part connected with a prolonged pipe, a flexible hose part connecting the first connecting part with the second connecting part, a first cover body arranged on the first connecting part and nested on the superposed part of the hose part and the first connecting part, as well as a second cover body arranged on the second connecting part and nested on the superposed part of the hose and the second connecting part. The first cover body is provided with a prolonged part which prolongs from the superposed part of the hose part and the first connecting part to the side of the hose part and the length of the prolonged part is more than the diameter of the hose part.

Description

technical field [0001] The present invention relates to vacuum cleaners, particularly improvements to their hoses. Background technique [0002] Hoses from existing vacuum cleaners, such as Figure 14-15 As shown, the two ends of the flexible accordion-shaped hose 151 are connected to the connecting parts 152, 153 respectively, and are connected to the vacuum cleaner body 154 through the connecting part 152 on one side of the body. However, in Figure 15 In the state of use of the vacuum cleaner shown, when the vacuum cleaner body 154 is pulled at steps such as the threshold, the hose 151 is pulled to pull the body closer, and the connecting part 155 on the hand side of the hose 151 (this part is connected to the hose) 151 and connecting part 153), and the overlapping part 156 (the overlapping part of the hose 151 and the connecting part 152) on one side of the vacuum cleaner body 154 is subject to load, and the repeated occurrence of this action will damage the hose.

AI Technical Summary

Problems solved by technology

There is a problem that the hose is prone to fatigue damage near the overlapped part on the hand side

[0004] Moreover, in recent years, vacuum cleaners have been stored as Figure 14 As shown, the vacuum cleaner body 154 remains upright, the hose 151 and the extension tube 157 are connected to the body as usual, and the fixing part 158 ​​provided on the extension tube 157 is fixed on the vacuum cleaner body 154 to realize its storage. However, In this state, the upper body of the concertina-shaped hose 151 near the overlapping portion on the hand side maintains an upper body that is bent at a sharp angle, so there is a problem of fatigue damage near the overlapping portion on the hand side.
