no. 1 approach

[0049] In this embodiment, as shown in FIGS. 2 to 9 , an elastic arm 121 is provided in the through hole 11 . One end of the elastic arm 121 is provided with an indenter 1211, the thickness of the indenter 1211 is obviously greater than the thickness of the elastic arm 121, specifically, the indenter 1211 protrudes downward, and in other embodiments, the indenter 1211 protrudes upward; The other end of 121 is connected to the inner wall of the through hole 11. Specifically, the elastic arm 121 is integrally formed with the windshield 1. Since the elastic arm 121 itself is made of elastic material, the pressure head 1211 can move up and down along the axial direction of the through hole 11. Specifically, when pressure is applied, the pressure head 1211 moves along the pressure direction; when the pressure is released, the pressure head 1211 resets under the action of the elastic arm 121 . In some other embodiments, the elastic arm 121 is elastically pivoted to the inner wall of...

no. 2 approach

[0062] In this embodiment, as shown in FIG. 10 , the windshield 1 further includes a linkage part 9, and the linkage part 9 includes an abutment 91 arranged on the upstream side of the windshield 1 and a trigger 92 hinged to the middle of the abutment 91. The trigger 92 moves in the through hole 11 along its axial direction. Specifically, both the abutting piece 91 and the triggering piece 92 are rod-shaped. The first end 911 of the abutting member 91 corresponds to the installation position of the first filter 23 , and the second end 912 of the abutting member 91 corresponds to the installation position of the second filter 25 . The first end 921 of the trigger member 92 is pivotally connected to the middle part of the abutment member 91 through the pivot 93 , and slide grooves 923 are symmetrically arranged on both sides of the middle part of the trigger member. A symmetrical third protrusion 111 extends toward the center of the through hole 11 from the position correspondi...

Abstract

The invention discloses a vacuum cleaner. The vacuum cleaner comprises a dirty air inlet, a clean air outlet and an air passage arranged between the dirty air inlet and the clean air outlet. A vacuumgenerator (8) is arranged in the interior of the air passage. The upstream of the vacuum generator (8) is equipped with a first filter (23). The upstream of the first filter (23) is provided with a second filter (25). The vacuum cleaner also comprises a state inductor (5). In the first state, the first filter (23) and the second filter (25) are joined together to trigger the state inductor (5). Inthe second state, the first filter (23) and the second filter (25) are not joined so that the state inductor (5) is not triggered. Through a micro-control switch, detection can be made as to whetherneglected installation of a master filter and a pre-filter occurs or not. Accordingly, cost is saved.

Description

technical field [0001] The present invention relates to a vacuum cleaner, in particular to a vacuum cleaner with double filters. Background technique [0002] With the continuous progress of society, the safety performance evaluation requirements of vacuum cleaners are getting higher and higher. In order to meet the current industrial standards of vacuum cleaners, general filters need to add a pre-filter outside the main filter to protect the main filter. device. [0003] Therefore, for the main filter and the pre-filter, it is necessary to set up the anti-leakage mechanism separately. The common anti-leakage mechanism is realized by the micro switch. After the assembly, the main filter and the pre-filter respectively touch a micro switch to achieve For the purpose of leak-proof installation, the use of two micro switches leads to high cost on the one hand, and on the other hand, it is necessary to design leak-proof installation structures for the main filter and the iron g...
