Fig. 1 to 5 show an embodiment of a dust collecting apparatus according to the present invention.

The dust suction apparatus includes a body 1, a dust cup 2, and a locking device. The dust cup 2 is a cylindrical structure, has a holding cavity with a certain volume, and is used for holding dust and dirt contained in the dust collection equipment. The dust cup 2 is the installation end for the one end of cylinder type structure extending direction, and it is provided with two first locking structure 8 to encircle the axis on the installation end. The first locking structure 8 is formed with locking grooves.

The machine body 1 is a core component of dust collection equipment and comprises a fan, an air inlet pipe, a filtering system and an exhaust pipe. The dirt passes through the air-supply line and gets into fuselage body 1 at the effect of fan, accomplishes the gas-dust separation back through filtration system, and the dirt falls in the holding cavity of dirt cup 2, and the air of separating out passes through the exhaust pipe and discharges, realizes clean function. The machine body 1 is provided with an installation cavity for installing the dust cup 2, and the installation cavity is a cylindrical cavity which is coaxial with the dust cup 2. The dust cup 2 is arranged in the mounting cavity along the mounting direction, and the mounting end is positioned in the mounting cavity. The installation direction is the central axis direction of the dust cup 2. The mounting plate 3 is arranged on the end face of the inner side of the machine body 1 corresponding to the mounting cavity, the extending direction of the mounting plate 3 is perpendicular to the mounting direction, and the mounting plate is of a circular plate-shaped structure matched with the mounting cavity.

The locking means comprises a first locking structure 8, a second locking structure 4 and drive means. The second locking structure 4 is a bolt structure matched with the first locking structure 8, and two locking devices are arranged corresponding to the first locking structure. The mounting plate 3 is provided with a slide groove 31 extending in a direction perpendicular to the mounting direction. The second locking formation 4 is slidably disposed on the mounting plate 3 by engagement with the slide slot 31. The sliding process of the second locking structure 4 has a locking position extending into the locking groove to lock the dirt cup 2 in cooperation with the first locking structure 8, and a release position away from the locking groove to disengage from the first locking structure 8.

The driving device comprises a first elastic part 7 and a power device, wherein the first elastic part 7 is a first spring arranged between the second locking structure 4 and the machine body 1. The second locking formation 4 moves to the locking position under the resilient force of the first spring. The end of the second locking structure 4 is provided with a pushing inclined plane, and the pushing inclined plane has an inclination which pushes the second locking structure 4 to move to a releasing position in the installation process of the dust cup 2. So set up for dirt cup 2 can push away second locking structure 4 with first locking structure 8 when the installation, and second locking structure 4 gets into the locking groove under the effect of first spring afterwards, thereby realizes directly pushing in of dirt cup 2 and locks.

the power device drives the second locking structure to move to the releasing position against the elastic force of the first elastic piece 7, and comprises a memory metal wire 5, a lead 6, a power supply and a control switch. The two ends of the memory metal wire 5 are respectively connected with the mounting plate 3 and the second locking structure 4. The power supply is connected to the memory wire 5 through a control switch and a wire 6. In this embodiment, the memory wire 5 is made of nitinol and has a wire diameter of 0.1 mm. The nickel-titanium alloy shrinks in length after the temperature exceeds a limit value; the length recovery performance after the temperature is lower than the limit value, and the response time is extremely fast and is within 0.1-0.2 s. After the control switch controls the power supply to electrify the memory metal wire 5, the memory metal wire 5 is heated up and shrinks when the temperature reaches about 80 ℃, the length shrinkage rate is about 3.9 percent, so that the second locking structure 4 is pulled to overcome the elastic force of the first spring to slide so as to be separated from the locking groove, and the dust cup 2 is unlocked.

First locking structure 8 and second locking structure 4 are copper zinc alloy, and all pass through surface finish, so set up to make coefficient of friction between the two very little, and wear-resisting, be convenient for frequently cooperate the use. Obviously, the first locking structure 8 and the second locking structure 4 may also be made of other materials with high hardness, wear resistance and low surface roughness after machining, such as beryllium copper, hard aluminum, 304, etc.

A guide rail groove 11 extending along the installation direction is formed in the machine body 1 corresponding to the inner wall of the installation cavity; the outer wall of the dust cup 2 is provided with a guide bulge 9 matched with the guide rail groove 11. The bottom of the rail groove 11 along the installation direction is provided with a second elastic member 10, and the second elastic member 10 is a second spring with the acting force parallel to the installation direction. The elastic force of the second spring drives the dust cup 2 in the released state to pop up. Preferably, at least two pairs of guide rail grooves 11 and guide protrusions 9 are provided around the central axis of the dirt cup 2 to be matched with each other. The guide protrusions 9 and the first locking structures 8 are provided at intervals around the periphery of the dirt cup 2.

So designed, when the dust cup 2 is installed, the second spring is in a pressing state. When the locking device on the dust cup 2 is unlocked, the dust cup 2 can be automatically popped out, so that the dust cup is convenient to disassemble and assemble.

the control switch is used for controlling the opportunity of supplying power to the memory metal wire 5, and is a key switch of the electric control type dust cup 2, the keys are better and labor-saving, the key positions are flexibly arranged, the keys can be integrated on the operation panel, the appearance is improved, the operation is more convenient and faster, and the technical sense is better.

as another embodiment, the driving device comprises a motor and a push rod mechanism acting on the second locking structure 4, and the moving direction of the push rod mechanism driven by the motor is parallel to the sliding direction of the second locking structure 4. The motor rotates forwards and backwards to control the second locking structure 4 to move at the locking position and the releasing position respectively.

As another embodiment, the driving means is an electromagnet and the second locking structure 4 comprises an active portion made of a magnetic material. The movement of the second locking structure 4 in the locking position and the release position is controlled by changing the direction of the current in the coil of the electromagnet.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
