Abstract

A cyclonic separating device ( 900 ) for an upright vacuum cleaner and an upright vacuum cleaner ( 1 ) with the same are disclosed. The cyclonic separating device ( 900 ) includes a dirt cup ( 37 ), a filter ( 92 ) and a cyclonic cone assembly ( 93 ). The filter ( 92 ) is disposed in the dirt cup ( 37 ) and includes a filter inlet ( 92 a ) and a filter outlet ( 92 b ) communicating between the filter inlet ( 92 a ) and an air outlet ( 373 ). The cyclonic cone assembly ( 93 ) includes a cyclone ( 931 ) and a cyclonic guide ( 932 ), in which a first end of the cyclone ( 931 ) is communicated with an air inlet ( 372 ), and the cyclonic guide ( 932 ) is fitted in a second end of the cyclone ( 931 ) and is detachably fitted over the filter ( 92 ) to spirally guide dirty air introduced into the cyclone ( 931 ) from the air inlet ( 372 ) to the filter inlet ( 92 a ).

First claim

What is claimed is:

1 . A cyclonic separating device for an upright vacuum cleaner, comprising:
a dirt cup comprising an air inlet and an air outlet; a filter disposed in the dirt cup and comprising a filter inlet and a filter outlet communicating between the filter inlet and the air outlet; and a cyclonic cone assembly comprising a cyclone and a cyclonic guide, wherein a first end of the cyclone is connected to the air inlet, and the cyclonic guide cooperates with a second end of the cyclone and is detachably fitted over the filter to spirally guide dirty air introduced into the cyclone from the air inlet to the filter inlet.

2 . The cyclonic separating device for the upright vacuum cleaner according to claim 1 , wherein the cyclonic guide comprises a first cylindrical surface and the filter comprises a second cylindrical surface, the cyclonic guide being detachably fitted over and cooperating with the filter by the first cylindrical surface and the second cylindrical surface.

3 . The cyclonic separating device for the upright vacuum cleaner according to claim 2 , wherein the filter is configured as a cylinder with an open end and a closed end; the open end of the filter defines the filter outlet and the filter inlet is formed on a side wall of the filter.

4 . The cyclonic separating device for the upright vacuum cleaner according to claim 3 , wherein the filter comprises a first section and a second section; the first section is configured to be a solid cylinder while the second section is configured to be a hollow cylinder; a first end of the second section is connected to a first end of the first section and a second end of the second section is open to define the filter outlet, and the filter inlet is formed on a side wall of the second section.

5 . The cyclonic separating device for the upright vacuum cleaner according to claim 4 , wherein the filter inlet comprises a plurality of filter pores that are evenly spaced apart and distributed in an axial direction and/or a circumferential direction of the second section.

6 . The cyclonic separating device for the upright vacuum cleaner according to claim 4 , wherein the cyclonic guide comprises:
a sleeve define a portion fitted over the first section; and a guide plate disposed between the sleeve and the cyclone to define, along with the sleeve and the cyclone, a spiral channel for the dirty air to spirally flow from the air inlet to the filter inlet.

7 . The cyclonic separating device for the upright vacuum cleaner according to claim 1 , wherein the cyclone and the cyclonic guide are fixedly connected to each other.

8 . An upright vacuum cleaner, comprising:
a brushroll; a motor assembly comprising a motor housing and a motor disposed within the motor housing, wherein a rotating axis of the motor and a rotating axis of the brushroll are disposed in a non-parallel manner, and the motor drives the brushroll rolling by a drive belt and is rotatable between a first upright position of tensioning the drive belt and a first oblique position of loosening the drive belt; a body assembly comprising a body, a bridging member mounted on the body and a cyclonic separating device comprising a dirt cup comprising an air inlet and an air outlet, a filter disposed in the dirt cup and comprising a filter inlet and a filter outlet communicating between the filter inlet and the air outlet, and a cyclonic cone assembly comprising a cyclone and a cyclonic guide, wherein a first end of the cyclone is connected to the air inlet, and the cyclonic guide cooperates with a second end of the cyclone and is detachably fitted over the filter to spirally guide dirty air introduced into the cyclone from the air inlet to the filter inlet, and the bridging member is rotatably connected to the motor housing to make the body rotatable between a second upright position and a second oblique position; wherein the bridging member causes the motor to move from the first oblique position to the first upright position when the body moves from the second upright position to the second oblique position.

9 . The upright vacuum cleaner according to claim 8 , further comprising:
a clutching device disposed between the bridging member and the motor, wherein the motor is moved from the first oblique position to the first upright position by the bridging member via the clutching device, when the body moves from the second upright position to the second oblique position.

10 . The upright vacuum cleaner according to claim 9 , wherein the clutching device comprises:
a first toggling block fixed on the motor; a second toggling block disposed on the bridging member; and a lever cam member rotatably disposed on the motor housing and defining two ends cooperating with the first toggling block and the second toggling block respectively.

11 . The upright vacuum cleaner according to claim 9 , wherein the clutching device comprises:
a first sliding rail disposed on the bridging member; a toggling tongue fixed on the motor and rotatable relative to the motor housing; and a lever member defining a first end slidably cooperating with the first sliding rail and a second end cooperating with an end of the toggling tongue.

12 . The upright vacuum cleaner according to claim 9 , wherein the clutching device comprises:
a slide chute formed on the bridging member; a triggering member rotatably supported on the motor housing and defining a first end with a sliding column slidably cooperating with the slide chute and a second end having a toggling rod adapted for prodding the movement of the motor; wherein the sliding column slides along the slide chute to make the triggering member rotate when the bridging member drives the movement of the slide chute, and the toggling rod prods the rotation of the motor relative to the motor housing when the triggering member rotates.

13 . The upright vacuum cleaner according to claim 9 , wherein the clutching device comprises:
a second sliding rail formed on the bridging member and defining a tail end having a second sliding rail tail groove formed by a recess in a surface of the tail end of the second sliding rail; and a lever rotating member rotatably disposed on the motor housing and defining two ends cooperating with the second sliding rail and the motor respectively, wherein when the body moves from the second upright position to the second oblique position, a first end of the lever rotating member slides from the second sliding rail tail groove to the second sliding rail, and the motor is moved from the first oblique position to the first upright position by a second end of the lever rotating member.

14 . The upright vacuum cleaner according to claim 13 , wherein the second sliding rail is configured as an arc second sliding rail with a rotating axis of the bridging member as a central axis.

15 . The upright vacuum cleaner according to claim 8 , wherein an elastic member is disposed between the motor and the motor housing and is configured to push the motor moving from the first upright position to the first oblique position when the body moves from the second oblique position to the second upright position.
