All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
[0031] Please refer to Figures 1-5, the present invention provides a technical solution: a connection structure between a dust cup of a vacuum cleaner and a base station, including: a suction port assembly 1 and a body assembly 2. The suction port assembly 1 is fixedly installed on the base station. A negative pressure assembly for generating suction is provided inside the base station. A slot 11 is provided on the suction port assembly 1. A dust suction channel 12 is provided on the bottom surface of the slot 11. A microswitch is provided inside the suction port assembly 1. The contact 13 of the microswitch penetrates through the bottom surface of the slot 11. A protruding pressing member 111 is provided on the side wall of the slot 11. A notch 14 is provided on one side of the suction port assembly 1. A charging assembly 15 is provided on the side wall of the notch 14. A charging spring piece 151 is provided on the charging assembly 15. The body assembly 2 includes a housing, and the housing includes a dust cup housing unit 21 and a body housing unit 22. The dust cup housing unit 21 and the body housing unit 22 are assembled to form a dust collection chamber 23 for collecting dust. A dust dumping port 211 is provided at the bottom of the dust cup housing unit 21. A dust cup bottom cover 24 is hinged to the dust cup housing unit 21. A first torsion spring 241 is provided on the rotating shaft of the dust cup bottom cover 24. The dust cup bottom cover 24 is used to close the dust dumping port 211. The housing is inserted into the suction port assembly 1. The dust cup housing unit 21 is inserted into the slot 11. The bottom of the dust cup housing unit 21 contacts the contact 13. An air inlet joint 221 is provided on the body housing unit 22. The air inlet joint 221 extends into the notch 14. The air inlet joint 221 is connected to an extension tube 3. A charging electrode corresponding to the charging spring piece 151 in position is provided on the extension tube 3. The charging electrode is connected to a battery pack inside the vacuum cleaner main body. A release button 25 is provided on the dust cup housing unit 21. The release button 25 corresponds to the pressing member 111 in position. The release button 25 is rotatably installed on the dust cup housing unit 21. The hanging end 251 of the release button 25 is inserted into the hook 242 of the dust cup bottom cover 24. An inclined transition surface 252 is provided between the hanging end 251 and the release button 25. A return spring is provided between the release button 25 and the dust cup housing unit 21. An electromagnet 26 is provided on the inner wall of the dust cup housing unit 21 on one side of the dust dumping port 211. The electromagnet 26 is connected to the battery pack through a cable. An iron block 243 corresponding to the electromagnet 26 in position is provided on the dust cup bottom cover 24.
[0032] A cyclone cone 27 is provided on the housing. The setting of the cyclone cone 27 causes the dust in the dust collection chamber 23 to rotate when being sucked out by the base station, making it easier to suck the dust in the dust cup clean.
[0033] The dust suction channel 12 is arranged obliquely and faces the cyclone cone 27, effectively avoiding the interference of the electromagnet 26 when sucking out dust, improving the dust removal effect, and enabling the cyclone cone 27 to play a better role.
[0034] A rubber ring 121 is provided at the top of the dust suction channel 12. The rubber ring 121 contacts the bottom surface of the dust cup housing unit 21, improving the sealing effect when the body assembly 2 is inserted downward into the suction port assembly 1, increasing the vacuum degree during dust suction, and ensuring the dust removal effect.
[0035] A dust shield 222 is provided inside the body housing unit 22. The dust shield 222 is rotatably mounted on the body housing unit 22. A second torsion spring is sleeved on the rotating shaft of the dust shield 222. The dust shield 222 is used to close the air inlet joint 221. When the air inlet joint 221 sucks dust, the dust shield 222 rotates backward to open. When the dust suction stops, it closes under the action of the second torsion spring. The dust shield 222 prevents dust leakage from the dust collection chamber 23.
[0036] The extrusion member 111 includes three convex ribs arranged in parallel. The ends of the convex ribs face the release button 25. The convex ribs squeeze the release button 25 through the ends to achieve the rotation and opening of the release button 25, and release the lock on the bottom cover 24 of the dust cup. The specific process is as follows: When the body assembly 2 is plugged into the suction port assembly 1, during the process of gradually inserting downward, the hanging end 251 of the release button 25 first contacts the convex rib. Since the thickness of the hanging end 251 is relatively thin, it will not be squeezed by the convex rib. Then the convex rib contacts the inclined transition surface 252, causing the release button 25 to be squeezed, so that the release button 25 rotates and opens, and the return spring between the release button 25 and the dust cup housing unit 21 is squeezed. On the contrary, when the body assembly 2 is separated from the suction port assembly 1, the release button 25 resets under the elastic force of the return spring.
[0037] A sealing cotton 244 matching the shape of the ash-dumping port 211 is provided on the bottom cover 24 of the dust cup, which effectively improves the closing and sealing effect of the dust cup and prevents dust and debris from leaking. The suction force of the electromagnet 26 can overcome the pre-pressure of the sealing cotton 244 and the dust cup housing unit 21 at the ash-dumping port 211 to ensure closing.
[0038] Working principle: When the whole vacuum cleaner after cleaning and sucking dust and debris is placed on the base station, the body assembly 2 is plugged into the suction port assembly 1 downward. At this time, the release button 25 on the side of the body assembly 2 is squeezed by the extrusion member 111, and the release button 25 rotates and opens. The hanging end 251 of the release button 25 disengages from the hook 242 of the bottom cover 24 of the dust cup, releasing the lock on the bottom cover 24 of the dust cup. At the same time, since the dust cup housing unit 21 squeezes the contact 13 on the bottom surface of the slot 11, the charging electrode on the extension tube 3 contacts the charging elastic piece 151 of the charging assembly 15, and the base station is triggered to work. After the base station is triggered, on the one hand, suction force is generated by the negative pressure assembly, and on the other hand, the battery pack of the vacuum cleaner is charged by the charging assembly 15, and the battery pack controls the electromagnet 26 to cut off the power, further releasing the lock on the bottom cover 24 of the dust cup.
[0039] After suction is generated inside the base station, the bottom cover 24 of the dust cup rotates and opens under the action of the suction force, so that the dust in the dust collection cavity 23 is sucked into the base station through the dust suction channel 12. After the base station works for a period of time (specifically, it can be set to about 20 seconds), it stops working. The electromagnet is energized, and the bottom cover 24 of the dust cup is reset under the action of the torsion spring, and the bottom cover 24 of the dust cup is locked by adsorbing the iron block 243 through the electromagnet 26, and the bottom cover 24 of the dust cup is closed in place.
[0040] When the whole vacuum cleaner is detached from the base station, the release button 25 is reset under the elastic force of the return spring, hooking the bottom cover 24 of the dust cup to prevent the bottom cover 24 of the dust cup from opening during falling and collision in the use process.
[0041] In actual implementation, after the base station is triggered, it is set that the negative pressure component is turned on accordingly, and the battery pack starts to be powered on. The power-on trigger of the battery pack will control the electromagnet 26 to be powered off. The negative pressure component is set to work for a specific working time T1, and the electromagnet 26 is set to be powered off for a time T2. When the power-off time T2 ends, the battery pack restores the power supply to the electromagnet. By setting the power-off time T2 to be equal to the working time T1, it is possible to turn on the negative pressure component, turn off the electromagnet 26, turn off the negative pressure component, and turn on the electromagnet.
[0042] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
