Abstract

A dust filter bag locking mechanism of a vacuum dust collector includes an upper shell body (12) and a dust collector lower body (11); the upper shell body (12) and the dust collector lower body (11) have two working states; the first working state is that the upper shell body (12) is connected with the dust collector lower body (11) into a whole, and the second working state is that the upper shell body (12) is separated from the dust collector lower body (11); an airflow inlet (14) is arranged on the upper shell body (12), a dust filter bag (10) is arranged at the airflow inlet (14); a pressing part (13) is arranged on the upper shell body (12) under the first working state, the pressing part (13) can press the dust filter bag (10) at the airflow inlet (14) of the upper shell body (12), a push button (6) is arranged on the upper shell body (12), and the push button (6) is pressed on the pressing part (13). The pressing part can be broken away from the dust filter bag or clamp the dust filter bag by pressing or releasing the push button, so the removal or the installation of the dust filter bag is very convenient.

Description

The bag dust filter locking mechanism of vacuum cleaner

Technical field

The utility model relates to a kind of vacuum cleaner.

Background technology

In the prior art, vacuum cleaner comprises body under upper shell, the dust catcher, two kinds of duties are arranged between the body under described upper shell and the dust catcher, first kind of duty be upper shell with dust catcher under be connected between the body and be one, second kind of duty is to be separated between the body under upper shell 1 and the dust catcher; Described upper shell is provided with air flow inlet, and this air flow inlet place is provided with bag dust filter.Under first kind of duty, the band dirt air-flow of suction enters in the bag dust filter through air flow inlet, and the clean gas flow after the filtration flows into negative pressure chamber after by filter felt.Filter bag is to be connected with upper shell by the gathering sill on the upper shell, and therefore under second kind of duty, changing filter bag is a kind of thing of trouble.

Summary of the invention

The purpose of this utility model is to provide a kind of filter bag bag dust filter locking mechanism of vacuum cleaner easily of changing.

The technical solution of the utility model is: a kind of bag dust filter locking mechanism of vacuum cleaner, comprise body under upper shell, the dust catcher, two kinds of duties are arranged between the body under described upper shell and the dust catcher, first kind of duty be upper shell with dust catcher under be connected between the body and be one, second kind of duty is to be separated between the body under upper shell and the dust catcher; Described upper shell is provided with air flow inlet, and this air flow inlet place is provided with bag dust filter; Under first kind of duty, described upper shell is provided with compressing member, and this compressing member is pressed in the air flow inlet place of upper shell to bag dust filter, and button is arranged on the upper shell, and this button is pressed on the compressing member.

The utility model compared with prior art has following advantage:

By pressing button or release-push, make compressing member break away from bag dust filter or clamp bag dust filter, then bag dust filter take off or install very convenient.

The specific embodiment

Referring to accompanying drawing 1 to accompanying drawing 4, a kind of bag dust filter locking mechanism of vacuum cleaner, comprise body [11] under upper shell [12], the dust catcher, two kinds of duties are arranged between the body [11] under described upper shell [12] and the dust catcher, first kind of duty is as shown in Figure 1, being connected between the body [11] under upper shell [12] and the dust catcher is one, and second kind of duty is as shown in Figure 3, is separated between the body [11] under upper shell [12] and the dust catcher; Described upper shell [12] is provided with air flow inlet [14], and this air flow inlet [14] locates to be provided with bag dust filter [10]; Under first kind of duty, described upper shell [12] is provided with compressing member [13], this compressing member [13] is located the air flow inlet [14] that bag dust filter [10] is pressed in upper shell [12], and button [6] is arranged on the upper shell [12], and this button [6] is pressed on the compressing member [13].

Referring to accompanying drawing 2 and accompanying drawing 4, be rotatably connected by pivot [4] between the middle part of described compressing member [13] and the upper shell [12]; Referring to accompanying drawing 2, under described first kind of duty, the first end [1] of described compressing member [13] is pressed in bag dust filter [10] on the upper shell [12], makes the duricrust portion of bag dust filter [10] and the plane of upper shell [12] closely contact mutually.The second end [3] of described compressing member [13] is against on the stop frame [2] on the body under the dust catcher [11], under first kind of duty, can't push button [6], and then bag dust filter [10] can not be separated with upper shell [12].Referring to accompanying drawing 3 and accompanying drawing 4, under second kind of duty, button [6] presses down a side of the second end [3], the first end [1] of described compressing member [13] breaks away from bag dust filter [10], and described bag dust filter [10] is separated with upper shell [12], and an end of promptly described button [6] is pressed in a side of the close the second end [3] on the compressing member [13], when pressing down button [6], compressing member [13] can rotate counterclockwise, and first end [1] meeting perk makes bag dust filter [10] and upper shell [12] be separated.
