Description

Technical Field

[0001] The present invention relates to the technical field of vacuum cleaners, and in particular to a vacuum cleaner capable of automatically collecting dust. Background Art

[0002] Vacuum cleaners are a common household cleaning appliance. Commonly used vacuum cleaners can be roughly divided into horizontal, vertical, handheld, etc. according to their different structural forms. Among them, the horizontal vacuum cleaner includes a main body, a vacuum blower, a connecting pipe, a floor brush and other parts. The vacuum blower is installed inside the main body. The vacuum blower is connected to the floor brush through a hose. When in use, the floor brush is operated to vacuum, and the main body is dragged through the connecting pipe to move. Horizontal vacuum cleaners are generally large in size, and the main body needs to be dragged frequently when in use, which is not very convenient to operate. The floor brush and vacuum blower of the upright vacuum cleaner adopt an integrated structure. When in use, the vacuuming operation can be completed by pushing the upright vacuum cleaner body. It is very suitable for cleaning the floor, but when it is necessary to clean the walls, furniture surfaces, and desktops, the entire vacuum cleaner needs to be lifted, which is inconvenient to use.

[0003] The existing cleaning method of the dust cup of a vacuum cleaner is to first remove the dust cup from the vacuum cleaner, open the dust cup cover and manually clean the dust inside the dust cup. When cleaning, the dust cup needs to be manually removed, which is a cumbersome cleaning process and easily dirty hands. In addition, the floating dust raised during cleaning easily causes secondary pollution to the surrounding environment, affecting the health of the user.

[0004] Therefore, it is necessary to provide a dust collecting device for automatically collecting dust to solve the above problems. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings, the purpose of the present invention is to provide a vacuum cleaner with automatic dust collection, which is easy for users to operate and use, can automatically absorb and collect dust in the dust cup, reduce the cleaning intensity of the user, and avoid secondary pollution of the surrounding environment caused by floating dust.

[0006] In order to achieve the above objectives, the technical solution adopted by the present invention is: a dust suction device with automatic dust collection, including a dust cleaner and a dust collecting mechanism; the vacuum cleaner includes a main unit and a dust cup detachably connected thereto, the dust collecting mechanism includes a charging bracket, a dust collecting duct detachably arranged on the charging bracket, and a dust collecting bucket, the charging bracket is provided with a dust cup placement groove from top to bottom for placing the dust cup, and a charging part is arranged below the dust cup placement groove, the dust collecting bucket is connected to the dust collecting duct through a bracket connecting pipe to automatically suck the dust in the dust cup into the dust collecting bucket for collection.

[0007] Furthermore, the dust cup includes a dust cup bottom, the dust cup bottom cover is provided with a dust cup cover, and the dust cup bottom is arranged in a funnel shape. By arranging the dust cup bottom in a funnel shape, the dust will not be suspended on the upper part of the dust cup during the suction process, and the dust can be gathered together during dust collection, thereby achieving the effect of rapid dust suction.

[0008] Furthermore, the top of the dust cup is engaged with the dust suction motor assembly, and the dust cup cover at the bottom is connected to the host through a dust cup quick release assembly. The dust cup quick release assembly includes a quick release button and a host clip. A push rod is horizontally arranged on the quick release button. The top of the host clip is connected to the bottom of the dust cup through a spring. When removing the dust cup, when the quick release button pushes the push rod to move in the first direction, the push rod abuts against the inclined surface on the host clip and pushes the host clip to move upward, so that the host clip is separated from the host. Compared with the existing press-type design, the sliding design of the quick release button is more ergonomic. The button can be slid to release the dust cup with one hand, which is more convenient to operate.

[0009] Furthermore, the bottom of the dust cup is connected to a bottom flap at the dust suction port through a torsion spring, and the dust cup also includes a self-locking component, and the self-locking component includes a self-locking button, and the hinged end on the self-locking button is hinged to the bottom of the dust cup, and at least part of the supporting end is in contact with the lower surface of the bottom flap. The supporting end on the self-locking component can effectively prevent the dust cup bottom cover from sinking downward due to excessive dust during the dust suction process, and form a gap with the bottom of the dust cup, thereby avoiding dust leakage, and the supporting end plays a certain supporting role on the bottom flap.

[0010] Furthermore, the charging bracket includes an upper bracket shell and a lower bracket shell that can be buckled together, the dust cup placement groove is opened on the upper bracket shell, the charging part is located on the lower bracket shell, the inner wall of the upper bracket shell and the inner wall of the lower bracket shell are buckled together to form a limited space for accommodating the dust collecting air duct, and a detection component is detachably provided on the bottom of the upper bracket shell.

[0011] Furthermore, the detection component includes a push-touch column, a microswitch located below it, and a detection fixing seat detachably connected to the bottom of the upper shell of the hanger. The push-touch column vertically penetrates the bottom wall of the dust cup placement groove and can move up and down along the bottom wall of the dust cup placement groove to trigger or disengage the microswitch. The microswitch is fixed on the detection fixing seat, and the push-touch column is slidably connected to the detection fixing seat. When the push-touch column moves downward, it can contact the trigger end on the microswitch. A number of guide baffles are also provided on the upper shell of the hanger, and the guide baffles correspond to the position of the self-locking assembly on the dust cup.

[0012] Furthermore, the dust collecting air duct is provided with a dust inlet and a dust outlet at the upper and lower ends respectively, the dust inlet is connected with the dust suction port at the bottom of the dust cup on the vacuum cleaner, a dust collecting channel for the dust in the dust cup to flow is formed between the dust inlet, the inner wall of the dust collecting air duct and the dust outlet, the dust collecting channel is coaxially arranged with the dust suction port, and a dust suction groove matching the dust inlet is provided at the bottom of the dust cup placement groove, so that dust can be more efficiently sucked from the dust cup into the dust collecting air duct, reducing loss, and making it difficult for dust to be blocked at the connection between the dust cup and the dust inlet.

[0013] Furthermore, the bracket connecting tube includes a connecting inner tube and a connecting outer tube fixedly sleeved on the outside thereof, one end of the connecting inner tube is fixedly connected to the dust outlet of the dust collecting air duct, and the other end is plugged into the dust collecting pipe on the dust collecting bucket, and the end of the dust collecting pipe away from the connecting inner tube is connected to the dust inlet on the dust bag. The setting of the bracket connecting tube can transport the dust in the dust cup to the dust collecting bucket for collection, and the setting of the connecting outer tube makes the appearance of the entire bracket connecting tube more beautiful. The dust entering the dust collecting air duct from the dust cup enters the connecting inner tube under the action of suction, and can enter the dust bag installed on the dust collecting mechanism through the connecting inner tube to be uniformly collected.

[0014] Furthermore, the dust collection bucket is divided into a dust collection bucket storage bin and an accessory storage bin by a partition plate, a front shell is buckled on the side of the dust collection bucket close to the vacuum cleaner, and a winding plate is protruding from the surface of the bottom of the dust collection bucket away from the front cover. The power cord can be led out from the side, and the power cord can be wound on the winding plate, so that the dust collection bucket as a whole can be placed against the wall without being unable to completely lean against the wall due to the protrusion of the power box, thereby reducing the space occupied by the dust collection bucket.

[0015] Furthermore, the vacuum cleaner also includes a dust suction duct assembly whose side is connected to the dust cup, the dust suction duct assembly includes a dust suction duct body, the dust suction duct body includes an air inlet end and an air outlet end, a dust sensor detection mechanism is symmetrically arranged along its axis on one side of the dust suction duct body close to the air outlet end, and a dust suction duct shell for the dust cup to be mounted is sleeved on the outer side of the dust suction duct body. The dust sensor detection mechanism can effectively detect dust at the suction port and provide dust blocking protection.

[0016] Beneficial effects of the present invention: The vacuum cleaner and the dust collecting component in the present invention cooperate with each other, which is convenient for users to operate and use. When cleaning the dust cup later, the user does not need to manually clean the inside of the dust cup. The dust in the dust cup can be automatically sucked and collected by the dust collecting component, thereby reducing the cleaning intensity of the user. At the same time, the dust in the dust cup will never come into contact with the outside world, which can effectively prevent floating dust from causing secondary pollution to the surrounding environment.

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0019] See attached Figures 1 to 19 As shown, an automatic dust collection device in this embodiment includes a vacuum cleaner 1 and a dust collection mechanism; the vacuum cleaner 1 includes a host 11 and a dust cup 4 detachably connected thereto, and the host 11 sucks the dust sucked by the vacuum end of the vacuum cleaner 1 into the dust cup 4 for collection; The dust collecting mechanism includes a charging bracket 15, a dust collecting duct 30 detachably arranged on the charging bracket 15, and a dust collecting bucket 32. A dust cup placement groove 153 for placing a dust cup is provided from top to bottom on the charging bracket 15, and a charging part 154 is provided below the dust cup placement groove 153, so that after the use of the vacuum cleaner 1, it can be vertically hung on the charging bracket 15 by placing the dust cup, without finding a wall or support to support the vacuum cleaner 1, which is convenient for the storage of the vacuum cleaner 1 after use. At the same time, the groove is provided on the charging bracket 15 so that after the dust cup is placed on the vacuum cleaner 1, the overall height of the vacuum cleaner 1 and the charging bracket 15 is lower than when the vacuum cleaner 1 is charged on the battery pack, and the storage and placement is more convenient.

[0020] Specifically, the dust cup placement groove 153 extends out of the outer wall of the charging bracket 15 on one side close to the charging contact 12 on the vacuum cleaner 1. This can effectively prevent the outer wall of the charging bracket 15 from interfering with the contact between the charging contact 12 on the vacuum cleaner 1 and the charging part 154, thereby ensuring the charging efficiency of the vacuum cleaner 1.

[0021] The dust collecting bucket 32 ​​is connected to the dust collecting air duct 30 through the bracket connecting tube 31, so that the dust in the dust cup is automatically sucked into the dust collecting bucket 32 ​​for collection. When the dust cup is placed in the dust cup placement groove 153, the dust collecting bucket 32 ​​starts to work, and the dust in the dust cup is sucked. The dust in the dust cup enters the dust collecting air duct 30 and enters the dust collecting bucket 32 ​​through the bracket connecting tube 31 for collection, so that the dust collected in the dust cup is cleaned up, and the user does not need to manually clean the dust cup, which reduces the frequency of dumping dust, and further improves the comfort and convenience of the user.

[0022] The dust cup includes a dust cup bottom 6, and the dust cup bottom 6 is covered with a dust cup cover 5. The dust cup bottom 6 is arranged in a funnel shape. By arranging the dust cup bottom 6 in a funnel shape, the dust will not be suspended on the upper part of the dust cup during the suction process. When collecting dust, the dust can be gathered together, so as to achieve the effect of rapid dust suction.

[0023] The top of the dust cup is engaged with the dust suction motor assembly, and the dust cup cover 5 at the bottom is connected to the host through the dust cup quick release assembly 14. The dust cup quick release assembly 14 includes a quick release button 141 and a host clip 142. A push rod 144 is horizontally arranged on the quick release button 141. The top of the host clip 142 is connected to the dust cup bottom 6 through a spring 13. When removing the dust cup, when the quick release button 141 pushes the push rod 144 to move toward the first direction, the push rod 144 abuts against the inclined surface 145 on the host clip 142 and pushes the host clip 142 to move upward, so that the host clip 142 is separated from the host. Compared with the existing press-type design, the sliding design of the quick release button 141 is more ergonomic. The button can be slid to release the dust cup with one hand, which is more convenient to operate.

[0024] When installing the dust cup, the top of the dust cup is inserted into the lower end of the dust suction motor assembly, and the bottom of the dust cup can be directly reset and locked with the host under the action of pressing and the elastic force of the spring 13. When removing, just push the quick button horizontally into the dust cup so that the push rod 144 contacts the host buckle 142, and the push rod 144 and the inclined surface of the host buckle 142 form a wedge structure. Under continuous pushing, the host buckle 142 can move upward to detach from the host, so as to realize the removal of the dust cup.

[0025] In some embodiments, a limit block 143 is provided on both sides of the dust cup cover 5 in the length direction of the main host fastener 142 to limit the main host fastener 142 to be unable to move in the horizontal direction and can only move up and down. A guide groove for guiding the main host fastener 142 to move up and down is also provided on the dust cup bottom 6 to ensure that the main host fastener 142 moves vertically upward under the pushing action of the push rod 144.

[0026] Specifically, the first direction is parallel to the length direction of the dust suction end of the vacuum cleaner 1 .

[0027] The dust cup bottom 6 is located at the dust suction port 9 and is connected to a bottom flip cover 7 through a torsion spring. The dust cup also includes a self-locking component 8, and the self-locking component 8 includes a self-locking button 81. The hinged end 82 on the self-locking button 81 is hinged to the dust cup bottom 6, and at least part of the supporting end 83 is in contact with the lower surface of the bottom flip cover 7. The supporting end 83 on the self-locking component 8 can effectively prevent the dust cup bottom cover from sinking downward due to excessive dust during the dust suction process, thereby preventing dust from running away. The supporting end 83 plays a certain supporting role on the bottom flip cover 7.

[0028] Compared with the prior art, which only uses the torsion spring self-locking to achieve the bottom flip cover 7 always covering the dust suction port 9 of the dust cup without external force, a self-locking component 8 is added. When the dust collecting bucket 32 ​​is working, the self-locking button 81 must be released first to automatically suck open the dust cup bottom 6. After dust collection, the torsion spring automatically resets the self-locking to effectively avoid the dust leakage problem of the dust cup bottom 6 flip cover.

[0029] In some embodiments, the self-locking button 81 is arranged in an L shape.

[0030] A cyclone cone 10 is also provided in the dust cup, and the cyclone cone 10 includes a cone body 101 and an upper cover 102 located on the top thereof. The upper cover 102 is screwed to the top of the dust cup and extends out of the top of the dust cup. When the cyclone cone 10 needs to be disassembled, it can be directly disassembled by rotating the upper cover 102, which can effectively prevent hands from directly contacting dust during cleaning.

[0031] Specifically, the cyclone cone 10 is provided with 6 cone holes, the tangent angle of the air inlet of each cone hole is 12.24°, the diameter of a single cone is 21 mm, the distance between the bottom of the cone body and the bottom flap 7 of the dust cup is 61.97 mm, and a rubber closing pad is provided at the bottom of the cyclone cone 10.

[0032] The charging rack 15 includes a rack upper shell 151 and a rack lower shell 152 that can be buckled up and down. The dust cup placement groove 153 is provided on the rack upper shell 151, and the charging part 154 is located on the rack lower shell 152. The inner wall of the rack upper shell 151 and the inner wall of the rack lower shell 152 are buckled to form a limited space for accommodating the dust collecting air duct 30. A detection component 16 is detachably provided at the bottom of the rack upper shell 151. The buckling structure is convenient for the installation and maintenance of the dust collecting air duct 30, the detection component 16 and the charging part 154 located in the above-mentioned limited space. The disassembly and assembly of the charging rack 15 are convenient and quick, and are convenient for users to install and operate. The detection component 16 is used to detect whether the dust cup is accurately placed in the dust cup placement groove 153, so as to avoid the dust cup being tilted and affecting the charging efficiency of the vacuum cleaner 1. At the same time, it also ensures that the dust suction port 9 on the dust cup corresponds to the position of the dust collecting air duct 30, so as to avoid the gap between the two and the phenomenon of dust running during automatic dust collection.

[0033] The detection component 16 includes a push-touch column 165, a micro switch 161 located below it, and a detection fixing seat 162 detachably connected to the bottom of the upper shell 151 of the hanger. The push-touch column 165 vertically passes through the bottom wall of the dust cup placement groove 153, and can move up and down along the bottom wall of the dust cup placement groove 153 to trigger or disengage the micro switch 161. The micro switch 161 is fixed on the detection fixing seat 162, and the push-touch column 165 is slidably connected to the detection fixing seat 162. When the push-touch column 165 moves downward, it can contact the trigger end on the micro switch 161. A plurality of guide baffles 18 are also provided on the upper shell 151 of the hanger, and the guide baffles 18 correspond to the position of the self-locking component 8 on the dust cup.

[0034] When collecting dust, the dust cup is placed in the dust cup placement slot 153. When the micro switch 161 is activated, it means that the dust cup is in place. At this time, the dust collection mechanism starts to work and can suck the dust in the dust cup into the dust collection box through the dust collection air duct 30. When the micro switch 161 is not touched, it will be displayed on the display screen that the dust cup is not in place. At this time, the dust collection work is not started, which effectively ensures the dust collection efficiency of the dust in the dust cup. At the same time, during the process of placing the dust cup, the guide baffle 18 gradually presses the self-locking button 81. When the dust cup is completely placed in the dust cup placement slot 153, the self-locking button 81 is in an unlocked state. At this time, the bottom flip cover 7 of the dust cup can be opened under the suction force of the dust collection barrel 32.

[0035] The top and bottom of the rack upper shell 151 near the charging part 154 are both provided with snap-fitting grooves, and the rack lower shell 152 is provided with snap-fitting pieces corresponding to the snap-fitting pieces. Through the mutual cooperation of the snap-fitting pieces and the snap-fitting grooves, the rack lower shell 152 is snap-fitted to the rack upper shell 151.

[0036] In some embodiments, the snap-fitting parts are symmetrically arranged along the center line of the length direction of the upper shell 151 of the hanger, so that the snap-fit ​​connection between the upper shell 151 of the hanger and the lower shell 152 of the hanger is more stable, and the lower shell 152 of the hanger will not separate from the upper shell 151 of the hanger even after long-term use.

[0037] The top of the fastening piece is tilted toward the inner wall of the lower shell 152 of the rack, so that the fastening piece and the fastening groove can be fastened more smoothly.

[0038] It should be noted that the arrangement of the fastening member and the fastening groove is not limited to the fastening member being arranged on the upper shell of the hanger and the fastening groove being arranged on the lower shell 152 of the hanger, as long as the fastening and opening of the upper shell 151 of the hanger and the lower shell 152 of the hanger can be satisfied. In some embodiments, the fastening groove can also be arranged on the upper shell 151 of the hanger, and the fastening member can be arranged on the lower shell 152 of the hanger, or the fastening groove and the fastening member can be arranged alternately.

[0039] A trigger column base 166 is fixedly connected to the bottom of the push-touch column 165. A base receiving groove for receiving the trigger column base 166 is provided on the detection fixing seat 162. The trigger column base 166 and the push-touch column 165 are integrally formed. When the trigger column base 166 moves up and down in the base receiving groove, the push-touch column 165 also moves up and down. The base receiving groove can also provide a certain guide for the up and down movement of the push-touch column 165. A guide slide block 164 matching with the guide slide groove 163 on the detection fixing seat 162 is provided on one side of the base receiving groove close to the micro switch 161 along its height direction. The guide slide groove 163 matches with the guide slide block 164 to further provide guidance for the up and down movement of the trigger column base 166. The lower end surface of the trigger column base 166 is connected to the bottom of the base receiving groove through the spring 13. When the force applied to the trigger column 165 to move it downward disappears, the trigger column 165 can automatically reset under the elastic force of the spring 13 itself.

[0040] In some embodiments, a limit hook is symmetrically arranged at the bottom of the trigger column base 166, and a sliding slot matching the limit hook is opened on the detection fixing seat 162. The coordinated arrangement of the sliding slot and the limit hook can limit the moving distance of the trigger column base 166 in the base accommodating groove, while ensuring that the trigger column base 166 will never separate from the detection fixing seat 162, thereby ensuring the stability of the installation of the pressing trigger column 165.

[0041] In some embodiments, the trigger column base 166 and the push-touch column 165 are both cylindrical structures, and the diameter of the trigger column base 166 is larger than the diameter of the push-touch column 165. When the top of the push-touch column 165 is not subjected to external pressure, the elastic force of the spring 13 can make the top of the push-touch column 165 protrude from the bottom wall of the dust cup placement groove 153. The trigger column base 166 with a larger diameter can limit the distance that the push-touch column 165 moves upward under the elastic force of the spring 13, and prevent the bottom of the push-touch column 165 from being separated from the dust cup placement groove 153 under the elastic force of the spring 13. It should be noted that the trigger column base 166 is not limited to being cylindrical, as long as its upper surface at least partially contacts the lower surface of the bottom wall of the dust cup placement groove 153 under the elastic force of the spring 13.

[0042] The switch mounting portion on the detection fixing seat 162 is threadedly connected to the bottom of the rack upper shell 151 through a locking screw. The detachable installation of the detection fixing seat 162 is convenient for the user to replace, repair or maintain the detection component 16 at any time.

[0043] An arc-shaped baffle 17 is provided at the junction of the side of the upper shell 151 of the hanger and the dust cup placement groove 153. The arc-shaped baffle 17 ensures that it will not interfere with the charging of the vacuum cleaner 1, and can also prevent the dust cup from rotating after being placed, ensuring that the dust cup is placed in place and the charging efficiency of the vacuum cleaner 1 is guaranteed.

[0044] The bottom of the dust cup placement groove 153 is provided with a trigger column slot 19 for the push trigger column 165 to move through. When the dust cup is not placed in the dust cup placement groove 153, the surface of the push trigger column 165 is not subjected to downward pressure. At this time, the top of the push trigger column 165 protrudes from the upper surface of the bottom of the dust cup placement groove 153.

[0045] A dust inlet 302 and a dust outlet 303 are respectively provided at the upper and lower ends of the dust collecting air duct 30. The dust inlet 302 is connected to the dust suction port 9 at the bottom of the dust cup on the vacuum cleaner 1. A dust collecting channel for the dust in the dust cup to circulate is formed between the dust inlet 302, the inner wall of the dust collecting air duct 30 and the dust outlet 303. The dust collecting channel is coaxially arranged with the dust suction port 9, so that the dust can be more efficiently sucked into the dust collecting air duct 30 from the dust cup, reducing the loss and making it difficult for the dust to be blocked at the connection between the dust cup and the dust inlet 302.

[0046] The diameter of the dust collecting air duct gradually decreases from the dust inlet 302 toward the dust outlet 303, so as to guide the dust entering the dust collecting air duct 30 to quickly enter the dust collecting bucket 32 ​​under the suction action of the dust collecting bucket 32 ​​and be collected uniformly, thereby effectively improving the dust suction efficiency.

[0047] In some embodiments, the dust collecting air duct 30 is funnel-shaped. The dust collecting air duct has a smooth surface, which can effectively prevent dust from hanging on the wall during dust collection, improve the dust collection efficiency, and also make it easier for users to use without frequent cleaning of the dust collecting air duct.

[0048] A dust suction groove 155 matching the dust inlet 302 is provided at the bottom of the dust cup placement groove 153. The dust suction groove 155 corresponds to the dust suction port 9 at the bottom of the dust cup and the dust inlet 302 on the dust collecting air duct 30, so as to prevent dust from escaping from the connection between the two when dust enters the dust collecting air duct 30 from the dust cup.
