Description
Technical field
The utility model relates to cleaner technology fields, and in particular to a kind of floating locking mechanism and dust catcher.
Background technique
The working principle of dust catcher is motor of dust collector high speed rotation, sucks air from air inlet, makes internal generate centainly
Vacuum, dust entered in dirt case by scrubbing brush, connecting tube.In wet type suction cleaners, filtered air is filtered using water, is made
Dust catcher running when be not in that dust flies to overflow, and wet type suction cleaners can dust suction, and can be clear by clear water or profession
Clean liquid preferably cleans obstinate substance, is liked by more and more users.In wet type suction cleaners, motor is located at water tank
Top, since the suction of motor is larger, when the water level in water tank is higher or moving dust collector causes the water surface in water tank to shake
Enter water in motor, will lead to the damage of motor；Moreover, water can also be blown out by dust catcher exhaust outlet.
Currently, existing Chinese patent literature such as CN206507879U, discloses the dust catcher with ball-cock assembly, including
The upper cover and water tank that mutually fasten, the first air inlet, dust bag filter device, air duct, bend pipe are set above the bend pipe other side
It is equipped with the ball-cock assembly fixed frame for being fixed on upper cover inner wall, ball-cock assembly, the ball-cock assembly are installed in ball-cock assembly fixed frame
The vacuum motor for being fixed on upper cover inner wall, ball-cock assembly floating ball salable vacuum motor when floating are provided with above device
Air inlet, the vacuum motor air outlet is connected to dust catcher exhaust outlet.
The dust catcher with ball-cock assembly of above patent document is floated by the floating ball of ball-cock assembly with movable valve plug
Upper end seals against the air inlet of the vacuum motor, although avoiding in water tank plus dilutional hyponatremia or when due to moving dust collector
The shaking of the water tank water surface enters water in vacuum motor, and still, floating ball needs liquid slowly to increase to drive and float, since liquid is slow
Slow increased buoyancy is smaller, and therefore, the inside of floating ball needs enough confined spaces, to guarantee that floating ball has foot relative to liquid
Enough small density makes floating ball float in a liquid, allows for floating ball in this way and needs biggish volume because floating ball be placed in it is molten
Inside liquid case, so accordingly reducing the volume of liquor box.
Utility model content
Therefore, the technical problem to be solved by the present invention is to overcome what existing dust aspirator water tank volume accordingly became smaller to ask
Topic, provides a kind of compact-sized, does not influence the floating locking mechanism and dust catcher of water tank capacity.
To solve the above problems, the floating locking mechanism of the utility model, comprising: mechanism body has inner cavity, Yi Jiyu thereon
The air inlet and air outlet that the inner cavity communicates；Whirlwind path is set to described interior intracavitary, the both ends difference in the whirlwind path
For air intake and outlet air end, the air intake is connected to the air inlet, the outlet air end protrude into the interior intracavitary liquid level it
Under；Floating stop member, is set to the inner cavity；When extracting the interior intracavitary gas out from the air outlet, outside the mechanism body
The liquid of side by the air inlet along the whirlwind path enter it is described interior intracavitary, drive be located at the interior intracavitary liquid
Spiral rotating, the liquid of spiral rotating rises along internal chamber wall pushes the floating stop member to move towards the air outlet until blocking institute
State air outlet.
The whirlwind path is helical form.
The whirlwind path is arranged in the middle part of the inner cavity, and the floating stop member is arranged around the whirlwind path.
Interior intracavitary first outer wall that there is the first inner wall being arranged around one week and be arranged around one week, first inner wall
Setting nested with first outer wall, the whirlwind path is arranged between first inner wall and first outer wall, described
Floating stop member is arranged around first outer wall, and the air intake is provided on first outer wall.
The inner surface of first outer wall is equipped with helicla flute, between the helicla flute and the outer surface of first inner wall
Cooperatively form the whirlwind path.
First inner wall and first outer wall are annular wall.
The upper end of first outer wall is concordant with the upper end of first inner wall to be arranged, and the lower end of the first outer wall is shorter than described
The lower end of first inner wall is arranged.
The mechanism body includes: lower part, including described first on the bottom wall of cup body is arranged in cup body and lower end
Inner wall, the air inlet are arranged on the cup body；Upper part has top plate and upper end with the lower part split settings
First outer wall of the downside of the top plate is set, and the air outlet is arranged on the top plate, the upper part peace
When on the lower part, the inner cavity is surrounded between the top plate and the cup body, first outer wall is inserted into the cup
In vivo, and it is nested with first inner wall setting.
First outer wall is equipped with the locating part that is oppositely arranged with the top plate, the floating stop member be set to the top plate with
Between the locating part, confession is surrounded between the top plate, first outer wall, the locating part and the inner wall of the inner cavity
The floating stop member is in the flotation chamber wherein to float up and down.
The locating part is to enclose muscle around the limit of first outer wall setting, and the interior of muscle and the inner cavity is enclosed in the limit
Wall gap setting.
It is filter screen that muscle is enclosed in the limit.
The air inlet is arranged close to the top plate.
