     DETAILED DESCRIPTION OF EMBODIMENTS 
       [0022]    Reference will be made in detail to embodiments of the present disclosure. The embodiments described herein with reference to drawings are explanatory, illustrative, and used to generally understand the present disclosure. The embodiments shall not be construed to limit the present disclosure. 
         [0023]    A cleaning appliance  10  according to embodiments of the present disclosure will be described with reference to drawings. As shown in  FIGS. 1-3 , the cleaning appliance  10  according to embodiments of the present disclosure includes a body  101 , a filtering member  102  and a dust tapping-off device. The body  101  has a clean air outlet  1011 , and the filtering member  102  is disposed at the clean air outlet  1011 . 
         [0024]    As shown in  FIGS. 1-3 , the dust tapping-off device according to embodiments of the present disclosure includes a sliding rail  103 , a sliding block  104 , an actuating rod  105  and a dust tapping-off member  106  configured for tapping the filtering member  102 . The sliding rail  103  is disposed on an outer surface of the body  101  and opposite to the clean air outlet  1011 . The sliding block  104  is slidably disposed on the sliding rail  103 . The actuating rod  105  is rotatably disposed on the sliding block  104 . The dust tapping-off member  106  is disposed on the actuating rod  105 . 
         [0025]    A dust tapping-off process of the cleaning appliance  10  according to embodiments of the present disclosure will be briefly described with reference to  FIGS. 1-3 . When the cleaning appliance  10  has been used for a period of time, the filtering member  102  is blocked gradually by dust and dirt, such that a suction of the cleaning appliance  10  is reduced, thereby decreasing a total cleaning efficiency of the cleaning appliance  10  (for example a vacuum cleaner). By rotating the actuating rod  105 , the dust tapping-off member  106  mounted to the actuating rod  105  may be driven to rotate, so that the dust tapping-off member  106  may tap the filtering member  102 . Furthermore, by driving the sliding block  104  to move along the sliding rail  103 , the actuating rod  105  and the dust tapping-off member  106  are moved, so that the dust tapping-off member  106  may tap different parts of the filtering member  102 , and thereby the whole filtering member  102  may be cleaned. That is to say, by providing the dust tapping-off device, the filtering member  102  does not need to be removed for cleaning. 
         [0026]    In the dust tapping-off device according to embodiments of the present disclosure, by providing the rotatable actuating rod  105  and mounting the dust tapping-off member  106  to the actuating rod  105 , the dust tapping-off member  106  may be rotated by rotating the actuating rod  105 , so that the dust tapping-off member  106  may tap the filtering member  102 , and thereby the filtering member  102  may be cleaned conveniently and easily. 
         [0027]    Therefore, the dust tapping-off device according to embodiments of the present disclosure has a simple structure and is easy to use. 
         [0028]    In the cleaning appliance  10  according to embodiments of the present disclosure, by providing the dust tapping-off device, the filtering member  102  may be cleaned conveniently and easily and the filtering member  102  does not need to be removed for cleaning. Therefore, the cleaning appliance  10  according to embodiments of the present disclosure has the simple structure, and is easy to clean and use. 
         [0029]    The body  101  and the filtering member  102  of the cleaning appliance  10  according to embodiments of the present disclosure may be known. For example, the filtering member  102  may be configured to be a high efficiency particulate air filter (HEPA). 
         [0030]    As shown in  FIGS. 1-3 , the cleaning appliance  10  according to some embodiments of the present disclosure includes the body  101 , the filtering member  102  and the dust tapping-off device. The dust tapping-off device includes the sliding rail  103 , the sliding block  104 , the actuating rod  105 , a handle  108  and the dust tapping-off member  106  configured to tap the filtering member  102 . 
         [0031]    The clean air outlet  1011  is provided in an upper surface of the body  101 , i.e. the clean air outlet  1011  is opened upwards. The upper surface of the body  101  is provided with a first engaging lug  1012  and a second engaging lug  1013 . The first engaging lug  1012  is provided with a first engaging groove, and the second engaging lug  1013  is provided with a second engaging groove. The sliding rail  103  includes a rail body  1031 , a first mounting portion  1032  and a second mounting portion  1033 . 
         [0032]    An upper end of the first mounting portion  1032  is connected to a first end of the rail body  1031  and a lower end of the first mounting portion  1032  is configured as a first fastener engaged in the first engaging groove. An upper end of the second mounting portion  1033  is connected to a second end of the rail body  1031  and a lower end of the second mounting portion  1033  is configured as a second fastener engaged in the second engaging groove. Thus, the sliding rail  103  may be mounted to the body  101  easily and steadily. 
         [0033]    Advantageously, the rail body  1031 , the first mounting portion  1032  and the second mounting portion  1033  may be formed integrally. The clean air outlet  1011  may be configured as a round hole, and the rail body  1031  may extend along a radial direction of the clean air outlet  1011 . 
         [0034]    As shown in  FIGS. 2 and 3 , in an embodiment of the present disclosure, the sliding block  104  has an accommodating cavity  1041  therein, both two opposite ends of the accommodating cavity  1041  are open, and the sliding rail  103  passes through the accommodating cavity  1041 . In other words, the sliding block  104  may be fitted over the rail body  1031 . Thereby, the structure of the dust tapping-off device may be reasonable and steady. 
         [0035]    Advantageously, a groove  1034  may be provided in an upper surface of the rail body  1031 , a protruding block  1042  may be disposed on a top wall surrounding the accommodating cavity  1041 , and the protruding block  1042  is fitted in the groove  1034 , so that the sliding block  104  may slide along the rail body  1031  steadily and easily. 
         [0036]    As shown in  FIG. 3 , in some embodiments of the present disclosure, the dust tapping-off device further includes a rolling element  107 . The rolling element  107  is rotatably disposed in the accommodating cavity  1041 , and also is mounted on the rail body  1031 . The actuating rod  105  passes through walls surrounding the accommodating cavity  1041  and is connected to the rolling element  107 . That is to say, the rolling element  107  may drive the actuating rod  105  to rotate. 
         [0037]    When the filtering member  102  is cleaned, the sliding block  104  is driven to move along the rail body  1031 , and the sliding block  104  may drive the rolling element  107  to roll. That is to say, during the movement of the sliding block  104  along the rail body  1031 , the rolling element  107  keeps rotating, so that the actuating rod  105  may keep rotating, and thus the dust tapping-off member  106  may be driven to tap the filtering member  102 . Thus, a user may complete the cleaning of the filtering member  102  only by operations of moving the sliding block  104  (without rotating the actuating rod  105  manually), and thereby the filtering member  102  may be cleaned conveniently and easily. 
         [0038]    Advantageously, a part of the rolling element  107  may be fitted in the groove  1034 , so that the rolling element  107  may roll steadily. The rolling element  107  may be configured as a rolling bearing. 
         [0039]    As shown in  FIG. 2 , in an embodiment of the present disclosure, the actuating rod  105  may be perpendicular to the sliding rail  103 . Thus, the structure of the dust tapping-off device may be reasonable. Specifically, the actuating rod  105  may extend along the radial direction of the clean air outlet  1011  as well. 
         [0040]    In a specific embodiment of the present disclosure, as shown in  FIG. 2 , a first portion  1051  of the actuating rod  105  extends leftwards out of the sliding block  104 , and a second portion  1052  of the actuating rod  105  extends rightwards out of the sliding block  104 . Furthermore, two dust tapping-off members  106  are provided. One dust tapping-off member  106  is disposed on the first portion  1051  of the actuating rod  105 , and the other dust tapping-off member  106  is disposed on the second portion  1052  of the actuating rod  105 , such that a cleaning speed of the dust tapping-off device may be improved, and thereby the filtering member  102  may be cleaned rapidly. 
         [0041]    Advantageously, one dust tapping-off member  106  may be movably fitted over the first portion  1051  of the actuating rod  105  along a left-right direction, and the other dust tapping-off member  106  may be movably fitted over the second portion  1052  of the actuating rod  105  along the left-right direction. The left-right direction is perpendicular to a paper in which  FIG. 3  is, i.e. the actuating rod  105  extends along the left-right direction. Thus, different parts of the filtering member  102  may be tapped by moving the two dust tapping-off members  106  along the left-right direction. 
         [0042]    The dust tapping-off member  106  may be configured as a cam, so that the structure of the dust tapping-off device may be reasonable. 
         [0043]    As shown in  FIG. 2  and  FIG. 3 , the handle  108  is disposed on the sliding block  104 , and thus the user may drive the sliding block  104  to move conveniently and easily. 
         [0044]    Advantageously, the handle  108  and the sliding block  104  may be formed integrally.
