Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0043] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0045] like Figure 1 As shown, in the first aspect, the embodiment of the present application provides a dust box 100, which relates to the technical field of cleaning equipment and is mainly used in a cleaning robot to store garbage sucked from the outside by the cleaning robot. It should be noted that the above-mentioned cleaning robot includes but is not limited to a sweeper, a handheld vacuum cleaner, a pet hair cleaner, a lawn mower, etc., and no specific limitation is made here.

[0046] like Figure 2 and Figure 3 As shown, the dust box 100 provided in this embodiment includes: an outer box body 110, an inner box body 120, a filter element 132 and a mounting element 133.

[0047] The outer box body 110 defines an open cavity 111, and a first suction port 112 communicating with the open cavity 111 is provided on the outer box body 110. At least part of the inner box body 120 is located in the open cavity 111, the outer box body 110 and the inner box body 120 are detachably connected, the inner box body 120 defines a dust collecting cavity 1211, and a second suction port 1212 is provided on the inner box body 120, the second suction port 1212 is communicated with the first suction port 112 and the dust collecting cavity 1211 respectively, and a first limiting portion 131 is provided on the inner box body 120. The filter element 132 is located at the connection between the first suction port 112 and the second suction port 1212. The mounting member 133 is located in the open cavity 111 and is used to cooperate with the inner box body 120 to fix the filter element 132. A first clamping member 140 is provided on the mounting member 133, and the first clamping member 140 is clamped with the first limiting portion 131 to achieve a detachable connection of the mounting member 133 to the inner box body 120.

[0048] It should be noted that the above “at least part of the inner box body 120 is located in the open cavity 111” means that the entire inner box body 120 may be located in the open cavity 111, or only part of the inner box body 120 may be located in the open cavity 111. In addition, the first suction port 112 is used to connect a suction device, such as a blower, a fan, a suction pipe, etc. The suction device can generate a suction airflow, so that the cleaning robot can suck external garbage into the dust collection cavity 1211.

[0049] like Figure 8 As shown, illustratively, the number of the first clamping member 140 and the first limiting portion 131 can be set to four respectively, and the four first clamping members 140 are arranged at intervals along the outer peripheral side of the mounting member 133, and the four first limiting portions 131 are arranged at intervals along the outer peripheral side of the second suction port 1212, and each first clamping member 140 is clamped with a first limiting portion 131. Of course, the number of the first clamping members 140 can also be one, two, three, five, etc., and the number of the first limiting portions 131 can also be one, two, three, five, etc., and no specific restrictions are made on the number of the first clamping members 140 and the first limiting portions 131. In addition, the filter 132 can be an element with a filtering effect such as HEPA and non-woven fabric. The mounting member 133 can be a mounting bracket with holes, a mounting plate with holes, a mounting rod, etc., as long as it does not affect the communication between the first suction port 112 and the second suction port 1212, and no specific restrictions are made on the structure of the filter 132 and the mounting member 133.

[0050] It should be mentioned that in the related art, the filter is fixed by the inner box of the dust box and the mounting piece, and the mounting piece is connected to the inner box by screws to achieve a detachable connection between the mounting piece and the inner box. However, when replacing the filter, it is necessary to use a disassembly tool such as a screwdriver to screw the screws to disassemble and install the mounting piece, which is time-consuming and labor-intensive, making it inconvenient to replace the filter, thereby affecting the user's experience.

[0051] In the dust box 100 provided in this embodiment, when the filter 132 needs to be replaced, the inner box body 120 is first removed from the outer box body 110, and then the first clamping member 140 on the mounting member 133 is operated to make the first clamping member 140 disengage from the limit of the first limiting portion 131, and the mounting member 133 and the filter 132 are removed from the inner box body 120, and then a new filter 132 is placed at the connection between the first suction port 112 and the second suction port 1212, and then the first clamping member 140 on the mounting member 133 is clamped on the first limiting portion 131, so that the mounting member 133 and the inner box body 120 jointly fix the filter 132, and finally the inner box body 120 is placed at the open cavity 111 and connected to the outer box body 110. Since in the above process of replacing the filter 132, it is not necessary to use a disassembly tool to disassemble the mounting member 133, so that the replacement of the filter 132 is more convenient and quick, thereby improving the user's experience.

[0052] like Figure 3 and Figure 4 As shown, in one embodiment, the first clamping member 140 includes a first clamping portion 141 and a first pressing portion 142 , the first clamping portion 141 is connected to the mounting member 133 and is clamped with the first limiting portion 131 , and the first pressing portion 142 is connected to the first clamping portion 141 .

[0053] like Figure 8 and Fig. 9 As shown, exemplarily, the first clamping portion 141 is a buckle with a clamping slot 1411, the first limiting portion 131 is a limiting buckle adapted to the clamping slot 1411, and the buckle is engaged with the limiting buckle at the clamping slot 1411. Of course, for the above example, the first limiting portion 131 can also be a limiting slot, and the first clamping portion 141 can also be a buckle adapted to the limiting slot, and the buckle is engaged with the limiting slot. The structures of the first clamping portion 141 and the first limiting portion 131 are not specifically limited here.

[0054] In this embodiment, since the first clamping part 140 includes the first clamping part 141 and the first pressing part 142, the first clamping part 141 is connected to the mounting part 133 and is clamped with the first limiting part 131, and the first pressing part 142 is connected to the first clamping part 141. In this way, the user can press the first pressing part 142 to drive the first clamping part 141 to deform so as to disengage from the limiting position of the first limiting part 131, and release the first pressing part 142 to reset the first clamping part 141, so as to realize the clamping connection between the first clamping part 141 and the first limiting part 131.

[0055] like Figure 8 and Fig. 9As shown, further, the first pressing portion 142 includes a first lever segment 1421, a second lever segment 1422 and a support segment 1423, one side of the first clamping portion 141 is connected to the mounting member 133, the first lever segment 1421 is connected to a side of the first clamping portion 141 away from the mounting member 133, the second lever segment 1422 is connected to an end of the first lever segment 1421 away from the first clamping portion 141, the support segment 1423 is connected to the connection between the second lever segment 1422 and the first lever segment 1421, and is supported on the inner box body 120.

[0056] In this embodiment, since the first lever segment 1421 is connected to the side of the first clamping portion 141 away from the mounting member 133, the second lever segment 1422 is connected to the end of the first lever segment 1421 away from the first clamping portion 141, and the support segment 1423 is connected to the connection between the second lever segment 1422 and the first lever segment 1421, and is supported on the inner box body 120. In this way, when the user presses the second lever segment 1422, the support segment 1423 serves as a lever fulcrum between the first lever segment 1421 and the second lever segment 1422, so that the second lever segment 1422 can drive the first lever segment 1421 to move, thereby driving the first clamping portion 141 to break away from the limit of the first limit portion 131, so as to facilitate the removal of the mounting member 133 from the inner box body 120, thereby replacing the filter element 132.

[0057] It should be understood that the above only exemplifies a structure of the first pressing portion 142. In other embodiments, the first pressing portion 142 includes a rotating arm and a double torsion spring, one end of the rotating arm is connected to the first clamping portion 141, the middle of the rotating arm is hinged to the mounting member 133, and the double torsion spring is connected between the mounting member 133 and the rotating arm. When replacing the filter element 132, the rotating arm is first pressed to overcome the elastic force of the double torsion spring to drive the first clamping portion 141 to break away from the limit of the first limiting portion 131, then the mounting member 133 and the filter element 132 are removed, and after replacing the new filter element 132, the rotating arm is loosened to reset it under the elastic force of the double torsion spring, so as to realize the clamping of the first clamping portion 141 with the first limiting portion 131. At this time, the mounting member 133 and the inner box body 120 jointly fix the filter element 132, which is also convenient for replacing the filter element 132. No specific restrictions are made on the structure of the first pressing portion 142.

[0058] like Figure 1 and Fig.11 As shown, in one embodiment, a sensing element 134 is provided on the mounting member 133 or the inner box body 120 , and a detection element 135 is provided on the outer box body 110 . The detection element 135 can cooperate with the sensing element 134 to detect whether the inner box body 120 is installed at a preset position of the outer box body 110 .

[0059] In this embodiment, the relative position of the inner box body 120 and the outer box body 110 can be detected by the cooperation of the detection element 135 and the sensing element 134, so as to detect whether the inner box body 120 is installed at the preset position of the outer box body 110, that is, to detect whether the inner box body 120 is installed on the outer box body 110 and installed in place, so as to reduce the risk of the cleaning robot performing cleaning operations when the inner box body 120 has not been installed. Specifically, when the inner box body 120 is installed on the outer box body 110 and installed in place, the detection element 135 can detect the sensing element 134, and the cleaning robot can determine that the inner box body 120 is installed in place, and prompt that the garbage suction function can be turned on. When the inner box body 120 is removed from the outer box body 110, the detection element 135 cannot detect the sensing element 134, and the cleaning robot can determine that the inner box body 120 has been removed, and automatically stop sucking external garbage.

[0060] Exemplarily, the sensing element 134 is a magnet, and the detecting element 135 is a Hall sensor. It is understandable that the Hall sensor has the advantages of stable performance, small size, low power consumption, high frequency, and anti-pollution. When used with a magnet, it can more accurately detect whether the inner box body 120 is installed on the outer box body 110 and whether it is installed in place.

[0061] Of course, the sensing element 134 can also be an electronic tag, and the detection element 135 can be a wireless radio frequency detector. The wireless radio frequency detector and the electronic tag can be used together to detect the relative position of the inner box body 120 and the outer box body 110 to determine whether the inner box body 120 is installed at the preset position of the outer box body 110.

[0062] like Figure 2 and Figure 5 As shown, in one embodiment, the dust box 100 also includes a second clamping member 150 and a first elastic member 136, a second limiting portion 137 is provided on the outer box body 110, the second clamping member 150 is movably connected to the inner box body 120, and the first elastic member 136 is respectively connected to the inner box body 120 and the second clamping member 150, and is used to apply elastic force to the second clamping member 150 so that the second clamping member 150 is clamped to the second limiting portion 137.

[0063] For example, the first elastic member 136 may be a cylindrical spring, a spring sheet, an elastic arm or other element capable of storing elastic potential energy, and the second clamping member 150 may be slidably connected to the inner box body 120 or may be hinged to the inner box body 120. The connection method between the first elastic member 136 and the second clamping member 150 and the inner box body 120 is not specifically limited herein.

[0064] In this embodiment, the second clamping piece 150 on the inner box body 120 is clamped with the second limiting portion 137 on the outer box body 110 to achieve a detachable connection between the inner box body 120 and the outer box body 110. This makes it easy to install the inner box body 120 on the outer box body 110 or remove the inner box body 120 from the outer box body 110, and in this process, there is no need to use disassembly tools, thereby improving the replacement efficiency of the filter 132.

[0065] like Figure 5 and Figure 6 As shown, further, a guiding portion 1213 and a connecting portion 1214 are provided on the inner box body 120, the second clamping member 150 includes a second clamping portion 151, a second pressing portion 152 and a sliding portion 153 connected between the second clamping portion 151 and the second pressing portion 152, the sliding portion 153 is slidably connected to the guiding portion 1213, the first elastic member 136 is connected between the connecting portion 1214 and the second pressing portion 152, and the second clamping portion 151 is clamped to the second limiting portion 137.

[0066] Exemplarily, the guide portion 1213 is a guide groove, and the sliding portion 153 is a slider. Of course, in other examples, the guide portion 1213 is a guide rail, and the sliding portion 153 is a slider with a slide groove. The slider cooperates with the guide rail through the slide groove, and the sliding connection effect can also be achieved. In addition, the connecting portion 1214 can be a connecting plate, a connecting rod, a connecting bracket, etc. The second clamping portion 151 is a buckle, and the second limiting portion 137 is a limiting groove, or the second clamping portion 151 is a plate-like structure with a slot, and the second limiting portion is a limiting buckle adapted to the slot.

[0067] In this embodiment, when the inner box body 120 needs to be removed, the second pressing portion 152 is pressed to overcome the elastic force of the first elastic member 136, and the second pressing portion 152 drives the second clamping portion 151 to disengage from the second limiting portion 137, and then the inner box body 120 can be taken out of the open cavity 111. When the inner box body 120 needs to be installed, at least a portion of the inner box body 120 is first placed in the open cavity 111, and then the second pressing portion 152 is released, so that the second clamping portion 151 is clamped with the second limiting portion 137 under the elastic force applied by the first elastic member 136.

[0068] like Fig.10 and Fig.12 As shown, further, the inner box body 120 includes a box body 121 and a surface cover 123, the box body 121 has the above-mentioned dust collecting chamber 1211, and is provided with the above-mentioned second suction port 1212, the surface cover 123 is connected to the box body 121, and a hand buckle groove 1231 is provided on the surface cover 123, and the hand buckle groove 1231 is used to accommodate at least part of the second pressing portion 152.

[0069] In this embodiment, when the inner box body 120 is disassembled, the second pressing portion 152 can be pressed through the buckle groove 1231 to drive the second clamping portion 151 to disengage from the limit of the second limit portion 137, and then the inner box body 120 can be taken out from the outer box body 110.

[0070] In another embodiment, the inner box body 120 may also be connected to the outer box body 110 by screws, and a detachable connection between the two can also be achieved. No specific limitation is made to the detachable connection method between the inner box body 120 and the outer box body 110.

[0071] like Figure 8 , Fig.10 and Fig.11 As shown, in one embodiment, the dust box 100 also includes a first sealing ring 161, and a positioning rib 1611 is provided on the outer peripheral side of the first sealing ring 161.

At least a part of the first sealing ring 161 is located in the sealing groove 114, and the positioning rib 1611 is penetrated through the positioning hole 115. The first sealing ring 161 abuts between the inner box body 120 and the outer box body 110, and is used to seal the gap between the inner box body 120 and the open edge of the open cavity 111, thereby extending the service life of the dust box 100.

[0072] like Figure 8 , Fig.11 and Fig.12 As shown, in one embodiment, the inner box body 120 includes a box body 121 and a box cover 122, the box body 121 has the above-mentioned dust collecting chamber 1211, and is provided with the above-mentioned second suction port 1212 and an opening 1215, the opening 1215 is communicated with the dust collecting chamber 1211, the box cover 122 covers the opening 1215, a hinged portion 1221 is provided on one side of the box cover 122, the hinged portion 1221 is hinged to the box body 121, and a third limiting portion 1222 is provided on a side of the box cover 122 away from the hinged portion 1221. The dust box 100 also includes a third clamping member 138 and a second elastic member 139, the third clamping member 138 is hinged to the box body 121, and the second elastic member 139 is connected to the box body 121 and the third clamping member 138 respectively, and is used to apply elastic force to the third clamping member 138 so that the third clamping member 138 is clamped to the third limiting portion 1222.

[0073] Exemplarily, the third clamping member 138 is a buckle, and the third limiting portion 1222 is a slot, or the third clamping member is a buckle with a slot, and the third limiting portion 1222 is a limiting buckle adapted to the slot.

[0074] In this embodiment, since the box cover 122 is hinged to the box body 121 through the hinge part 1221, and the box cover 122 is provided with the third limit part 1222, on this basis, the third clamping member 138 is hinged to the box body 121, and the second elastic member 139 is respectively connected to the box body 121 and the third clamping member 138, and is used to apply elastic force to the third clamping member 138 so that the third clamping member 138 is clamped to the third limit part 1222. In this way, it is convenient for the user to open and close the box cover 122 to dump garbage. Specifically, when it is necessary to dump garbage, press the third clamping member 138 to overcome the elastic force of the second elastic member 139, so that the third clamping member 138 is disengaged from the limit of the third limiting portion 1222, and then rotate the box cover 122 to open the opening 1215 of the box body 121. After dumping the garbage, rotate the box cover 122 to close the opening 1215, and then release the third clamping member 138 so that it is clamped with the third limiting portion 1222 under the elastic force applied by the second elastic member 139.

[0076] In this embodiment, under the action of the suction device, the dust box 100 can suck external garbage into the dust collecting chamber 1211 through the first dust collecting port 113 and the second dust collecting port 1223 in sequence. At the same time, the filter 132 allows the airflow at the second suction port 1212 to pass through and leave the garbage in the dust collecting chamber 1211, reducing the risk of garbage entering the suction device.

[0077] like Figure 8 and Fig.10 As shown, further, the dust box 100 also includes a second sealing ring 162, which abuts between the side of the box body 121 having the opening 1215 and the box cover 122, and is used to seal the gap between the edge of the box cover 122 and the edge of the opening 1215 of the box body 121 to reduce the risk of garbage leakage in the dust collecting chamber 1211.
