Blower assembly 3

Referring to fig. 6-11, the arrow X direction is the length direction of the hand-held cleaner (fan assembly), the Y direction is the width direction, and the Z direction is the height direction. A blower assembly 3 is provided to the body 2 for generating a suction air flow. The fan assembly 3 is disposed above the handle 22. The fan assembly 3 and the battery pack 4 are respectively arranged at two ends of the handle 22. The fan assembly 3 includes a fan 31, a filter 33 and a fan housing 32. The blower 31 and the filter 33 are located on both sides of the handle axis O in the width direction of the hand-held cleaner 101, respectively, and the blower 31 is used to generate suction air flow. The filter 33 is used to filter the exhaust air flow of the blower 31.

The front housing 325 defines mounting holes 327 for the removable filter element 33. The fan housing 32 is provided with a wire hole 328, and the wire hole 328 communicates with the air outlet passage 323 and the external space of the fan housing 32. The motor wire may extend from the fan housing cavity 321 to the outside of the fan housing 32 through the wire passing hole 328.

Dust cup assembly 1

Referring to fig. 12-14, with simultaneous reference to fig. 2-5, the dirt cup assembly 1 is disposed on the housing 2 in front of the blower assembly 3 along the direction of extension of the suction duct 21. The dust cup assembly 1 comprises a cyclone separation chamber 12 and a dust collection chamber 13, wherein the cyclone separation chamber 12 and the dust collection chamber 13 are communicated through an ash throwing port 14, and the cyclone separation chamber 12 and the dust collection chamber 13 are arranged side by side along the width direction of the handheld dust collector 101.

Referring to fig. 14-19, the dirt cup assembly 1 includes a housing 11, the housing 11 including a side wall 111 and a bottom wall 112 defining a cyclonic separating chamber 12 and a dirt collecting chamber 13 therein, at least a portion of the side wall 111 and at least a portion of the bottom wall 112 together defining the dirt collecting chamber 13 for collecting dirt. The dust collection chamber 13 is provided outside the cyclone separation chamber 12 and communicates with the cyclone separation chamber 12 through the dust throwing port 14. Specifically, the casing 11 is elliptical and divided into two parts in the width direction thereof, one part is the cyclone chamber 12, and the inner wall of the cyclone chamber 12 is cylindrical, so that the separation efficiency can be effectively improved. The dust collection chamber 13 is provided at one side of the cyclone separation chamber 12, the housing 11 includes a peripheral wall and a bottom wall 112, a cover 132 is provided on the bottom wall 112, and the cover 132 is used to open/close the dust discharge port 131 of the dust collection chamber 13. The housing 11 includes a first end 113 and a second end 114 opposite to each other along the length of the dirt cup assembly 1, the bottom wall 112 is disposed at the first end 113, the bottom wall 112 is provided with a dust discharge opening 131 and a cover 132 for opening/closing the dust discharge opening 131, and the dust throwing opening 14 is disposed near the second end 114.

Referring to fig. 16-21, the area of the dust discharge opening 131 is smaller than the cross-sectional area of the dust collection chamber 13 in a direction perpendicular to the length of the dust cup assembly 1. A guide structure 18 is provided between the sidewall 111 and the dust discharge port 131 for guiding dirt in the dust collection chamber 13 to the dust discharge port 131. The dirt path defined by the guide structure 18 becomes progressively smaller in the direction of extension from the second end 114 to the first end 113. The guide structure 18 is substantially horn-shaped, and the inner diameter of the guide structure 18 gradually becomes smaller toward the ash discharge port 131. The use of the dust discharge opening 131 having a smaller area than the cross-sectional area of the dust collection chamber 13 may result in that a portion of the dirt may get stuck to the edge of the dust collection chamber 13 near the dust discharge opening 131 when the dust collection chamber 13 is emptied. The dirt at the edge position is not easily cleaned, and therefore, a guide structure 18 is provided between the ash discharge port 131 and the sidewall 111 to guide the dirt to avoid the edge above the ash discharge port 131 to be smoothly discharged from the ash discharge port 131. Further, the cover 132 has an area larger than the area of the dust discharge port 131 and smaller than the cross-sectional area of the dust collection chamber 13.

In order to realize the opening/closing of the cover 132, the dirt cup assembly 1 is further provided with a switch structure 15. The switch structure 15 is disposed at the bottom wall 112. The switch structure 15 is used for unlocking the cover 132 so that the cover 132 can move relative to the bottom wall 112 to open the dust outlet 131 of the dust collecting chamber 13, and at least part of the switch structure 15 penetrates the bottom wall 112. Referring to fig. 23-25, the arrows indicate the direction of movement of the parts. The switch structure 15 includes a trigger member 151 and a locking member 152, where the trigger member 151 can make the locking member 152 be in an unlocked state after being stressed. The trigger 151 extends through the bottom wall 112 and the external structure may trigger the trigger 151 from below the bottom wall 112 without the need for additional structure around the side wall 111. The trigger 151 moves in a direction perpendicular to the bottom wall 112 to drive the locking member 152 to move in a direction parallel to the bottom wall 112. The outer surface of the touch element 151 is substantially in the same plane with the outer surface of the bottom wall 112, so that the touch element 151 can be effectively prevented from being touched by mistake.

Referring to fig. 19-21, the cyclone chamber 12 has an air inlet 122 formed in the inner wall 111 thereof, the air inlet 122 being disposed at the first end 113 of the housing 11. The cyclonic separating chamber 12 further comprises a guide wall 121, the guide wall 121 serving to guide the airflow entering from the air inlet 122 into the cyclonic separating chamber 12 for cyclonic separation. A mounting cavity 16 is defined between the guide wall 121 and the bottom wall 112, and at least a portion of the switch structure 15 is disposed within the mounting cavity 16. In this way, space can be effectively saved. Referring to the figures, the height of the air inlet 122 is greater than the height of the guide structure 18 along the length of the dirt cup assembly 1. The guide structure 18 has a relatively small height, and effectively increases the effective volume of the dust collection chamber 13 while performing a guide function.

Referring to fig. 14 to 15, the dust discharge port 131 is provided at the corresponding bottom wall 112 of the dust collection chamber 13. In other embodiments, the ash discharge port 131 may also partially or fully cover the corresponding bottom wall 112 of the cyclone chamber 12. Specifically, the bottom wall 112 includes a first region 115 corresponding to the cyclone chamber 12 and a second region 116 corresponding to the dust collecting chamber 13, and the trigger 151 is disposed in the first region 115. The area of the cover 132 is smaller than the area of the first region 115. The cover 132 has a smaller area, which can effectively reduce the contact area of the base station 20, and at the same time, the area of the cover 132 (i.e. the area of the ash discharge opening 131) is reduced, so that the suction force can be increased, and the dust in the dust cup assembly 1 can be more easily sucked into the dust collection cavity. The edge of the ash hole 131 is located inside the edge of the sidewall 111.

Referring to fig. 14-15, the dirt cup assembly 1 further includes a locking structure 17 for unlocking/locking the dirt cup assembly 1, the locking structure 17 being located at the intersection of the first region 115 and the second region 116 of the bottom wall 112. The locking structure 17 includes a button 171, the button 171 protruding from the bottom wall 112.

The cover 132 includes an open state and a closed state, the cover 132 being provided with a retaining structure 133, the retaining structure 133 being configured to maintain the cover 132 in the closed state at all times without being subjected to external forces. When the hand-held cleaner 101 is placed on the base station 20, the cover 132 is in an openable state, but under the action of the holding structure 133, the cover 132 continues to seal the dust outlet 131, and if dirt is present at the dust outlet 131, and the gravity of the dirt is large, the cover 132 may be opened. When the suction motor in the base station 20 is started, a large suction force is generated, and at this time, the suction force acting on the cover 132 overcomes the force generated by the holding structure 133, so that the cover 132 is in an opened state, and at this time, dirt in the dust collecting chamber 13 is sucked into the dust collecting chamber. When the suction motor is stopped, the cover 132 returns to the closed position under the action of the holding structure 133, and is in the closed state. The retaining structure 133 may be a torsion spring, although other mechanical structures are possible.

Referring to fig. 16-21, the second end 114 of the dirt cup assembly 1 is provided with a filter support 51, and the opposite ends of the filter support 51 are respectively provided with a first filter 52 and a second filter 53, the first filter 52 being arranged in the cyclone chamber 12, and the second filter 53 being arranged outside the cyclone chamber 12. The cross-section of the second filter 53 is larger than the cross-section of the cyclonic separating chamber 12 and smaller than the cross-section of the dirt cup assembly 1, with a plane perpendicular to the separation axis. The first filter 52 and the second filter 53 are both pre-motor filters.

Base station

Referring to fig. 1, and also to fig. 26 and 27, base station 20 is adapted to interface with at least a portion of surface cleaning apparatus 101, at least with a dirt cup assembly of the surface cleaning apparatus, and the hand-held cleaner may be integrally disposed on the base station, or the dirt cup assembly may be separately removable from the base station. Referring to fig. 28, the base station includes a docking assembly 28, a base 27, and an extension bar 26 connecting the docking assembly 28 and the base 27, the docking assembly 28 and the base 27 being disposed at both ends of the extension bar 26, respectively.

Referring to fig. 28, 29 and 31, the docking assembly 28 includes a housing 281 and a receiving bracket 282, the housing 281 defining the dust collection chamber 22, the receiving bracket 282 for receiving at least a portion of the surface cleaning apparatus. The case 281 is for supporting the receiving bracket 282. The case 281 may be integrally formed with the receiving bracket 282, and the two may be separately provided. To receive the cover, the receiving bracket 282 further includes a receiving slot 284 for receiving the cover and a channel 285 in communication with the receiving slot 284. Specifically, the receiving bracket 282 includes a docking slot 286, the docking slot 286 being configured to dock at least a portion of a surface cleaning apparatus, and in particular a dirt cup of the surface cleaning apparatus, with a portion of the dirt cup extending into the docking slot 286. Therefore, the cover of the dust collecting chamber is made smaller, at least smaller than the cross-sectional area of the dust collecting chamber, so that the occupation space of the docking slot 286 can be effectively reduced. The abutting groove 286 is defined by a top wall 291 and a peripheral wall 294 provided around the top wall 291. The abutment groove 286 may be recessed downwardly from the top wall 291, or the peripheral wall 294 may extend upwardly relative to the top wall 291.

The area of the cover is smaller than the area of the third region 292. When the hand-held cleaner is docked to the base station, the cover can be opened outwardly, i.e., the base station must accommodate the lower cover 272, if the cover is very large, the docking slot 286 corresponding to the cover will become large, at least a portion of the base station will become large, and the docking slot 286 is merely docking and does not accommodate dirt, and thus, an oversized docking slot 286 will waste space.

Referring to fig. 31, the receiving slot 284 has a generally flared shape, with a gradually decreasing cross-sectional area in a direction away from the docking slot 286 until connected to the channel 285. The channel 285 may extend into the dust bag 29 of the dust collection chamber 22. The receiving bracket 282 defines a funnel-shaped receiving slot 284 and a channel 285 communicating the dirt collection chamber 22 with the receiving slot 284 for directing dirt in the dirt cup assembly to the dirt collection chamber 22.

Since the handheld cleaner further comprises an extension tube and a cleaning head, in order to facilitate docking of the entire handheld cleaner to the base station, referring to fig. 29, the peripheral wall 294 is configured with a notch 295 for accommodating part of the main unit and/or the extension tube of the handheld cleaner, and the base station may also be provided with a charging contact 296 for charging the handheld cleaner, and a charging contact 296 is provided at the notch 295 for facilitating charging. The charging contacts 296 are typically provided on the top wall 291 so that the hand-held cleaner can be docked with the charging terminals 25 (see fig. 26 or 27) of the hand-held cleaner when the hand-held cleaner is placed on a base station. The butt joint of the two is completely maintained by the gravity of the handheld dust collector, and the gravity is not required to be maintained by external force similar to other elastic structures, so that the cost is effectively reduced, and the reliability of the equipment can be increased. The number of the charging contacts 296 is two, and the charging contacts are respectively arranged at two sides of the notch 295.

Referring to fig. 30-34, a dust bag mount 23 for mounting a dust bag 29 is provided within the dust chamber 22, the dust bag mount 23 being pivotally disposed within the dust chamber 22.

Referring to fig. 32-34, to prevent the dust bag 29 from being missed, the base station is provided with a dust bag detection device, the dust bag 29 monitoring device being configured to detect whether the dust bag 29 is mounted on the dust bag mounting frame 23. Further, the dust bag 29 monitoring device is configured to detect whether the dust bag 29 is mounted on the dust bag mounting frame 23 only when the dust bag mounting frame 23 is in the first position. The advantage of this is that even if the dust bag mounting frame 23 is in the first position, but no dust bag 29 is mounted on the dust bag 29 mounting bracket, the base station can prompt the user that no dust bag 29 is mounted or that the suction motor 21 in the base station is not working, avoiding that dirt in the dust cup assembly is transferred into the dust collecting chamber 22 without the dust bag 29.

With continued reference to fig. 32-34, the dust bag detection device includes a tamper proof switch that is in an on state when the dust bag mount 23 is in the first position, the suction motor 21 in the base station is operable, and is in an off state when the dust bag mount 23 is in the second position, the suction motor 21 is inoperable. The anti-tamper switch may include a signal generator, which may be, for example, an infrared receiver/transmitter or other detectable device, which communicates with the wiring board 223 by sending a first signal to the controller, which identifies the presence of the dust bag 29 within the dust collection cavity 22.
