Embodiment 1

[0018] The upright quick conversion vacuum cleaner of the present embodiment is as figure 1 As shown, the vacuum cleaner housing 2 is equipped with an exhaust fan as a negative pressure source, and the negative pressure source communicates with the dust collection barrel, and the dust collection barrel is connected to the first interface 1-1 of the three-way switching valve 1 . The second interface 1-3 of the three-way switching valve 1 is connected to the main dust-absorbing head (floor brush) 3 through the flexible pipe 2-3, and the third interface 1-2 is connected to the attached dust-absorbing head (floor brush) as an accessory through the pipeline 2-2. not shown in the figure).

[0019] The specific internal structure of the three-way switching valve 1 is as follows: figure 2 As shown, the expanded diameter sections between the second and third interfaces and the internal channel of the valve body are respectively equipped with flap valve leaves Y-3 and Y-2 with two ext...

Embodiment 2

[0023] The basic structure of the quick-change vacuum cleaner of this embodiment is basically the same as that of Embodiment 1. The difference is as Figure 4 As shown, the protruding ends of the pin shafts Z-3 and Z-2 of the two valve blades are respectively fixedly connected to the toothed wheels, and the two toothed wheels are linked to each other through the synchronous toothed belt 4 . In this way, the conversion control basically the same as that in the first embodiment can be realized.

Embodiment 3

[0025] The basic structure of the quick-change vacuum cleaner of this embodiment is basically the same as that of Embodiment 1. The difference is as Figure 5 As shown, the protruding ends of the pin shafts Z-3 and Z-2 of the two valve leaves are respectively fixedly connected with the two equal-length connecting frame rods 5, and the other ends of the two connecting frame rods are connected by connecting rods to form a parallel four-bar linkage mechanism. In this way, the conversion control basically the same as that in the first embodiment can also be realized.

Abstract

The invention is concerned with a kind of speediness control conversion value and speediness conversion cleaner with this value. The shell of cleaner has exhaust fan as source in vacuum. And the source in vacuum connects with dust collector canister. The entrance of gas to the dust collector canister connects with the first joint of triton control conversion value. The second joint connects with main head for dust collector through pipe, and the third joint connects with assistant head for dust collector, and there are two valve vanes with limit position close to the second and third heads oftriton control conversion value. When the two valve vanes are at the second position, the second joint breaks with the first joint and the third joint connect with the first joint. It realizes the conversion of main and assistant head of dust gathering by control the open and break state of the two valve vanes with right operation to fit user's demand.

Description

technical field [0001] The invention relates to a fast switching valve and a fast switching vacuum cleaner using the valve, belonging to the technical field of cleaning appliances. Background technique [0002] Vacuum cleaners are widely used cleaning tools. Its basic structure is that the casing is equipped with an exhaust fan as a negative pressure source, and the air inlet of the negative pressure source is connected to the main dust collector head (commonly known as the ground brush) through the dust collection tube and the pipeline. In order to facilitate the removal of dust from special parts such as crevices and corners, vacuum cleaners are usually equipped with attachments such as small floor brushes. When in use, it can be replaced as needed. [0003] Usually, when replacing the cleaning head, it is necessary to unplug the hose originally connected to the main cleaning head, and then plug it into the selected cleaning head attachment, which is not convenient enoug...
