DETAILED DESCRIPTION

[0025] The preferred embodiments of the utility model are described below in conjunction with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0026] Referring to FIGS. 1-8, the utility model provides a one-key dust discharging structure of a handheld dust collector, which comprises a holding handle 100, a power base 110 connected to the bottom end of the outer wall of the holding handle 100, a battery placed in the power base 110 for power supply, a dust collection device 500 arranged at the bottom of the right side of the outer wall of the holding handle 100, an air duct 200 communicated with the top end of the outer wall of the holding handle 100, and the dust collection device 500 arranged to generate suction force after being powered on, the air duct 200 arranged to suck dust and transport it to the dust cup 400 for temporary storage, the dust cup 400 installed at the end of the holding handle 100 away from the dust collection device 500, the top end of the dust cup 400 connected to the bottom end of the outer wall of the air duct 200, the bottom end of the dust cup 400 hinged to the bottom cover 410, the hinged seat 420 arranged at the connection between the bottom end of the dust cup 400 and the bottom cover 410, the bottom end of the bottom cover 410 hinged to the hinged seat 420 through a rotating shaft, the torsional spring arranged on the rotating shaft of the bottom cover 410 to open the bottom cover 410 outward, and the bottom cover 410 arranged to close the opening on the right side of the hinged seat 420 to prevent dirty from being discharged from the front end of the hinged seat 420 during the dust collection process, and the torsional spring arranged to rotate the bottom cover 410 outward without external force, thereby facilitating personnel to discharge the dirty.

[0027] The opening mechanism for opening the bottom cover 410 is arranged in the holding handle 100, and the opening mechanism comprises a pull ring 300 installed on the top inner wall of the holding end of the holding handle 100. A steel wire 310 is fixed to one end of the outer wall of the pull ring 300 close to the air duct 200. The other end of the steel wire 310 is provided with a release top block 320 arranged on the inner wall of the bottom end of the air duct 200 and away from one side of the holding handle 100. The release top block 320 arranged can only move up and down at the bottom end of the air duct 200. A bottom cover release button 430 is hinged to the top end of the outer wall of the dust cup 400 below the release top block 320. The end of the bottom cover release button 430 away from the steel wire 310 is buckled to the upper end of the bottom cover 410. The bottom end of the release top block 320 abuts against the top end of the outer wall of the bottom cover release button 430 away from the bottom cover 410. A top block spring 321 for resetting is installed on the back side of the bottom end of the outer wall of the release top block 320. The bottom end of the top block spring 321 abuts against the top end of the outer wall of the dust cup 400. Specifically, when a person pulls the pull ring 300, the arranged steel wire 310 will press downward to the release top block 320, so that the top end of the left side of the bottom cover release button 430 will rotate downward, and the right side thereof will rotate upward, thereby separating from the upper end of the bottom cover 410. The bottom cover 410 will rotate to the right side under the action of the torsion spring due to the lack of buckling of the bottom cover release button 430, and the person can pour out the dirt stored in the dust cup 400;

[0028] Dust cup release buttons 210 are slidingly arranged on the front and rear ends of the outer wall of the air duct 200 and left of the release top block 320. A buckle groove is formed in the top end of the outer wall of the dust cup 400 corresponding to the dust cup release button 210. The bottom end of the dust cup release button 210 is buckled to the buckle groove. Specifically, when a person needs to remove the dust cup 400, only needs to press the dust cup release buttons 210 on the front and rear sides inward, so that the bottom end of the dust cup release button 210 separates from the buckle groove, and then the person can directly separate the dust cup 400 from the dust collection equipment 500. A reset spring is arranged between the opposite sides of the two dust cup release buttons 210. The reset spring is arranged to ensure that the top end of the outer wall of the release top block 320 corresponding to the dust cup release button 210 is provided with a wedge-shaped groove. The dust cup release button 210 is arranged to be downwardly curved at the position corresponding to the release top block 320. The wedge-shaped groove and the downward curvature are arranged to enable the person to pull the pull ring 300 to enable the steel wire 310 to press the release top block 320 downward, so that the bottom cover release button 430 can be opened.

[0029] The use process of the utility model is as follows: the skilled person in the art will first, personnel can fix dust cup 400 on one side of dust collection equipment 500 when using, then place battery in power base 110, then start switch, dust collection equipment 500 will make air duct 200 produce suction when working, and personnel can suck air and dirt together through air duct 200, and air duct 200 will deliver dirt to dust cup 400 for storage;

[0030] When personnel need to clean the dirt stored in dust cup 400, personnel can hook and pull pull ring 300 with fingers, so that steel wire 310 can press and release top block 320 to move downward, so that top block spring 321 is in compression state, then release top block 320 will make the top end left side of bottom cover release button 430 downward rotate, and its right side will rotate upward, so as to separate from the upper end of bottom cover 410, and bottom cover 410 will rotate right under the action of torsion spring due to lack of buckling of bottom cover release button 430, so personnel can pour out the dirt stored in dust cup 400, personnel can buckle bottom cover release button 430 after pouring out, and the utility model discloses a handheld dust collector, which is not limited to the form of the whole dust collector, and can be dust cup 400 below air duct 200 or dust cup 400 above air duct 200.

[0031] The above is only the preferred embodiment of the utility model, and any skilled person in the art can modify the utility model by using the technical solutions described above or modify it into equivalent technical solutions. Therefore, any simple modification or equivalent replacement according to the technical solutions of the utility model is within the scope of protection required by the utility model.
