The second housing 12a further includes an extending portion 123a, and the extending portion 123a is located on two opposite sides of the second housing 12 a. Specifically, the extension 123a has a space, and a portion of the sidewall 122a of the second housing 12a can be an outer sidewall (facing the outer side of the dust box 10) of the extension 123a, and of course can also be an inner sidewall of the extension 123 a. When the first housing 11a and the second housing 12a are closed, the space of the extension 123a does not directly communicate with the accommodation chamber 100, but communicates with the passage chamber 101. The extending portion 123a is opened with an air outlet 120, and the air outlet 120 is opened on, for example, an outer sidewall of the extending portion 123a, and a part of the sidewall 122a, for example, the outer sidewall of the extending portion 123a is opened with the air outlet 120, so as to communicate with a space of the extending portion 123 a.

The second housing 12a may be opened with a communication hole 1211a, and the communication hole 1211a may penetrate the top wall 121 a. In the present embodiment, the number of the communication holes 1211a may be plural, and the shape is, for example, a circle, an ellipse, a square, or the like. The communication hole 1211a is for communicating the passage chamber 101 and the accommodation chamber 100.

The screen assembly includes a first screen 15a and a second screen 16 a. The filtering accuracy of the second screen 16a is smaller than that of the first screen 15 a. In other words, the second screen 16a may be used as a coarse screen (primary screen) and the first screen 15a may be used as a fine screen (high efficiency screen). For example, for second screen 16a and first screen 15a to be both mesh-like, the mesh size of second screen 16a may be larger than the mesh size of first screen 15 a. For example, the second screen 16a may have 4 meshes, the first screen 15a may have 100 meshes, and the entire size of the second screen 16a and the entire size of the first screen 15a are adapted to the communication hole 1211a, i.e., the size of the meshes of the second screen 16a is larger than that of the meshes of the first screen 15 a. Of course, as shown in fig. 5, the first screen 15a may have a foldable screen.

The second screen 16a is provided in the second casing 12a, and may be positioned inside the communication hole 1211a or outside the communication hole 1211a to cover the communication hole 1211 a. The second screen 16a may be a single body which covers the plurality of communication holes 1211 a. The second screen 16a may be a plurality of screens, and is correspondingly positioned in each of the communication holes 1211 a. The first filter 15a may be disposed in the space of the extending portion 123a to cover the air outlet 120, so as to filter the airflow flowing out of the air outlet 120. The number of the second filter screens 16a is, for example, at least two, and corresponds to at least two air outlets 120, that is, each air outlet 120 is provided with one second filter screen 16 a.

Through corresponding the first filter screen 15a that sets up at two at least air outlets 120, form the filtration system of many high-efficient filter screens, so a plurality of first filter screens 15a can filter respectively the air current of flowing through two at least air outlets 120, can promote filter effect and filtration efficiency, can further promote the speed that the air current flows. Further, the plurality of communication holes 1211a may increase an area through which the air flow passes, thereby preventing an air flow from being obstructed due to the accumulation of the garbage objects such as the foreign materials in the receiving chamber 100.

The second exemplary construction of the dust box 10 described above may use the same construction of the snap assembly 30 as the first exemplary construction of the dust box 10. Of course, a second exemplary configuration of the dust box 10 may also provide a different configuration of the latch assembly 30 than the first exemplary configuration of the dust box 10, and another example of the latch assembly 30 may be described in detail below.

Referring to fig. 5 and 6, the latch assembly 30 may include a pressing portion 31a, a latch lever 32a, and an elastic portion 33a, wherein the pressing portion 31a is connected to the latch lever 32 a. For example, the latch bar 32a may be integrated, for example, the pressing portion 31a is connected to a middle region between both ends of the latch bar 32 a. The two ends of the fastening rod 32a are respectively provided with a fastening part 321a in a protruding manner. Of course, as shown in fig. 5, the number of the latch levers 32a may be two, and the two latch levers are respectively connected to two sides of the pressing portion 31a, and each latch lever 32a has one end connected to the pressing portion 31a and the other end extending away from the pressing portion 31a and provided with a latch portion 321 a. The elastic portion 33a is provided on the pressing portion 31a, and the elastic portion 33a is rotatable with respect to the dust box 10. The pressing portion 31a is rotatable with respect to the dust box 10 by the elastic portion 33 a.

As shown in fig. 5, the other side of the second housing 12a may be further formed with a rod receiving groove 1212a spaced apart from the groove 1210 a. Specifically, when the second housing 12a and the cover 13a are closed, the rod receiving groove 1212a and the channel 101 may be isolated from each other and not communicated with each other, so as to ensure that the suction force of the dust suction port 110 can better suck the garbage. As shown in FIG. 6, the snap rod 32a and the pressing portion 31a can be received in the rod receiving groove 1212 a. For example, the part of the groove body of the rod-receiving groove 1212a corresponding to the snap rod 32a is adapted to the external shape of the snap rod 32a, and the part of the groove body of the rod-receiving groove 1212a corresponding to the pressing portion 31a is adapted to the external shape of the pressing portion 31 a. When the snap lever 32a and the pressing portion 31a are accommodated in the lever accommodating groove 1212a, the elastic portion 33a is elastically deformed as the pressing portion 31a is pressed.

The elastic portion 33a includes, for example, a rotating lever 331a, a torsion spring 332a, and a connecting body 333a, and the connecting body 333a is fixed to the pressing portion 31 a. The connecting body 333a is provided with a torsion spring slot (not labeled), for example, a middle region of the connecting body 333 a. The rotating rod 331a is disposed through the connecting body 333a along the length direction of the connecting body 333a, and specifically passes through one end of the connecting body 333a, the torsion spring placing groove, and the other end of the connecting body 333a in sequence, and the two ends of the protruding connecting body 333a are disposed. The torsion spring 332a is sleeved on a portion of the rotating lever 331a located in the torsion spring placing groove. Of course, an elastic body of another shape may be used instead of the torsion spring 332 a.

Both ends of the rotating lever 331a may be directly rotatably provided to the second housing 12 a. The rotation lever 331a may also be provided to the second housing 12a to be indirectly rotatable. For example, as shown in fig. 5 and 6, the fastening assembly 30 may further include a fixing portion 34a, the fixing portion 34a is opened with a connecting body placing groove, and the fixing portion 34a is opened with a hole on each of two side walls of the connecting body placing groove, and a portion of the rotating rod 331a protruding from both ends of the connecting body 333a is inserted into the hole to be rotatably connected. When the pressing portion 31a and the locking rod 32a are placed in the rod receiving groove 1212a, the fixing portion 43a is fixedly connected to the second housing 12a, for example, by screws. Both ends of the torsion spring 332a may be limited by the second housing 12a and the connecting body 333a, respectively, so as to be elastically deformed during the relative rotation.

When the latch rod 32a is accommodated in the rod accommodating groove 1212a, the latch portion 321a extends toward the cover 13 a. When the pressing portion 31a is pressed toward the bottom wall 111a, the pressing portion 31a rotates along the axis of the rotating rod 331a, and the torsion spring 332a can further elastically deform, so as to drive the fastening portion 321a to displace and move toward the bottom wall 111 a. When the pressure applied to the pressing portion 31a disappears, the torsion spring 332a makes the pressing portion 31a rotate reversely (relative to the pressed state) due to the elastic restoring force, and drives the buckling portion 321a to move reversely and away from the bottom wall 111 a.

The body of the cover 13a has a fastening hole (not shown) at a position corresponding to the fastening portion 321 a. When the pressing portion 31a is not pressed, the engaging portion 321a protrudes from the engaging hole, and thus the engaging connection can be performed. When the pressing portion 31a is pressed and pressed toward the bottom wall 111a, the pressing portion 31a rotates toward the bottom wall 111a along the axis of the rotating lever 331a, so that the locking portion 321a is displaced toward the bottom wall 111a, and thus the locking portion does not protrude out of the locking hole of the cover 13a, thereby facilitating the releasing process. When the pressing portion 31a is pressed further, the latch lever 32a can be limited by the lever receiving groove 1212a, so that the pressing portion 31a is prevented from being pressed and further moving.

By providing the elastic rotation type snap assembly 30, the snap connection can be made more convenient, the structural stability is better, and the structural design can be further simplified compared with the former exemplary structure.

Referring to fig. 7 to 9, the third specific exemplary structure of the dust box 10 can be described in this embodiment, and specifically, the structure can be as follows:

as shown in fig. 9, the dust box 10 has at least two communication holes 1211b spaced apart from each other. A continuous hole 1211B and another continuous hole 1211B are formed in at least two of the continuous holes 1211B, and a projection point D of a center C of the dust suction port 110 on a line connecting a center A of the continuous hole 1211B and a center B of the other continuous hole 1211B is located between centers A, B of the two continuous holes 1211B. The center C of the dust suction port 110 is a perpendicular line connecting the centers A, B of the two communication holes 1211b, and an intersection point D at which the perpendicular line intersects the center A, B of the two communication holes 1211b is located between the centers A, B of the two communication holes 1211 b. The center C of the suction port 110 means a geometric center of a geometric shape identical to and matching the shape of the suction port 110 or a center of gravity of a homogeneous object identical to and matching the shape of the suction port 110. Similarly, the center A, B of the communication hole 1211b refers to a geometric center of a geometric shape that is the same as and matches the shape of the communication hole 1211b or a center of gravity of a homogeneous object that is the same as and matches the shape of the communication hole 1211 b.

As shown in fig. 7 and 8, the dust box 10 may include a first housing 11b, a second housing 12b, and a cover 13 b. The second housing 12b is covered on the first housing 11b to form an accommodating cavity 100, and the cover 13b is covered on the second housing 12b to form a channel cavity 101.

As shown in fig. 8, the first housing 11b is, for example, arranged in a groove shape, and may specifically include a bottom wall 111b and a side wall 112b arranged around the bottom wall 111b, and the bottom wall 111b and the side wall 112b enclose a groove-shaped structure. When the second housing 12b is covered on the first housing 11b, the groove structure of the first housing 11b may be covered into the receiving cavity 100. The first housing 11b may have a dust suction port 110 formed in a side wall 112b, for example, and the dust suction port 110 communicates with the groove structure, that is, the receiving chamber 100.

The second housing 12b may be substantially plate-shaped, for example. The second housing 12b may have at least two communication holes 1211b formed therein, and the communication holes 1211b extend from one side surface of the second housing 12b to the other side surface of the second housing 12 b. The communication hole 1211b communicates with the accommodating chamber 100. The arrangement of the at least two communication holes 1211b can form a plurality of flow directions for the air flow entering the dust collection opening 110, prevent the sucked garbage and the like from being only accumulated at the position adjacent to the dust collection opening 110, and disperse and accumulate along with different air channels, thereby improving the space utilization rate of the dust box 10.

As shown in fig. 9, a projection point D of the center C of the dust suction port 110 on a connecting line of the center a of the one communicating hole 1211B and the center B of the other communicating hole 1211B is located between the centers A, B of the two communicating holes 1211B, so that the air flow entering the dust suction port 110 can be divided to two sides of the center C, for example, the air flow flows to the one communicating hole 1211B, the other communicating hole 1211B, and the like, thereby improving the flowing direction of the air flow, enabling the sucked garbage objects to be preferentially stacked from two sides, and improving the space utilization rate of the dust box 10.

In some embodiments, as shown in fig. 8, the arrangement direction of the two communication holes 1211b may be substantially along the length direction of the second housing 12b, so that the two communication holes 1211b are disposed at intervals and located in the adjacent areas of the two ends of the second housing 12b in the length direction thereof (the connection line direction of the two ends is substantially the length direction of the second housing 12 b), which enables the following air flow to be preferentially accumulated on the two sides when the garbage objects are sucked into the dust box 10, thereby improving the situation that the garbage objects are concentrated in the adjacent areas of the dust suction opening 110, reducing the phenomenon of blocking the dust suction opening 110, and improving the space utilization rate of the dust box 10. Further, the two communication holes 1211b may be located adjacent to a side of the first housing 11b opposite to the dust suction port 110 (a side away from the dust suction port 110), and a line connecting centers of the two communication holes 1211b and the center of the dust suction port 110 may be a triangle, for example, an isosceles triangle. Of course, the second housing 12b structure may also be the second housing 12 as shown in the first exemplary configuration of the dirt box 10.

Of course, the arrangement position of the communication hole 1211b may be adjusted by specifically designing the structures of the first housing 11b, the second housing 12b, and the third housing 13b, and for example, there may be the following cases:

as shown in fig. 10, in one embodiment, the second housing 12b may include a top wall and a side wall, while the first housing 11b is provided in a plate shape, and the third housing 13b is provided to cover the first housing 11b, and the second housing 12b separates the receiving chamber 100 and the passage chamber 101. At least two of the communication holes 1211b may be partially opened in the top wall and partially opened in the side wall to communicate the receiving chamber 100 and the passage chamber 101. Of course, at least two communication holes may be provided on both side walls of the second housing 12b opposite to each other.

As shown in fig. 11, in another embodiment, the first housing 11b includes a bottom wall and a side wall, and the second housing 12b is provided to cover the side wall of the first housing 11. The third housing 13b is provided to cover the bottom wall of the first housing 11 b. The second housing 12b partitions the accommodation chamber 100 and the passage chamber 101. At least one of the at least two communication holes 1211b is opened in the second housing 12b, and at least another one is opened in a side wall of the first housing 11b, and both communicate the accommodation chamber 100 and the passage chamber 101. Of course, the at least two communication holes 1211b may be opened on both side walls of the first casing 11 b.

Alternatively, the dust box assembly 1 may include at least two filter screen assemblies each for filtering the air flow of one of the communication holes 1211 b. Each of the screen assemblies includes the first screen 15b, and the number of the first screen 15b and the communication holes 1211b may correspond one to one. The first screen 15b may be disposed in the communication hole 1211b to filter the air flow, and may be partially received in the communication hole 1211b, for example. Of course, the first filter 15b may be disposed on one side of the second casing 12b facing the cover 13b and correspondingly cover the communication hole 1211b to filter the air flow. Optionally, each screen assembly may further include a second screen 16b, and the filtering accuracy of the first screen 15b is greater than that of the second screen 16 b. The second screen 16b may be disposed in the through hole 1211b, and the first screen 15b is covered on the second screen 16b, and the first screen 15b is closer to the cover 13b than the second screen 16 b. In other words, the first screen 15b is located downstream of the second screen 16b, and the air flow passes through the second screen 16b and the first screen 15b in turn to be double-filtered.

Through setting up two at least intercommunicating pores 1211b, correspond and set up two at least first filter screen 15b, can get into the air current that holds chamber 100 through dust absorption mouth 110 and form two at least wind channels to change the wind channel flow direction, optimize the flow of air current, thereby make rubbish inhaled dirt box 10 can obtain more effective the depositing, thereby can improve dirt box 10's space utilization, make dirt box 10's filtration efficiency better, cleaning efficiency is higher, so can promote dust absorption mouth 110's suction.

The cover 13b covers the second housing 12b to enclose the channel cavity 101. For example, a groove (not shown) is formed on a side of the cover 13b facing the second housing 12b, and the groove is enclosed by the cover 13b and the second housing 12b when the cover and the second housing are covered together to form the channel cavity 101. Of course, the structure of the cover 13b and the second housing 12b may also be the same as the cover 13b and the second housing 12b in the first exemplary structure of the dust box.

Optionally, the dust box 10 may further include a rotating member 17b, and the cover 13b may be rotatably connected to the first housing 11b through the rotating member 17b, so as to cover or open the first housing 11b and the cover 13 b. When the first housing 11b and the cover 13b are opened from each other, the second housing 12b can be exposed, and cleaning, maintenance, and the like of the first filter 15b and the second filter 16b can be facilitated. Specifically, the rotating member 17b may include a rotating shaft 171b, a first shaft receiving portion 172b disposed on the first housing 11b, and a second shaft receiving portion 173b disposed on the cover 13b, and both ends of the rotating shaft 171b are respectively embedded in the first shaft receiving portion 172b and the second shaft receiving portion 173b, so that the first housing 11b and the cover 13b can rotate relatively.

Alternatively, the cover 13b may include a cover body 131b and a screen upper cover 132 b. The cover body 131b has a mounting hole 130b formed at a position corresponding to the first screen 15b, and the mounting hole 130b communicates with the passage chamber 101. When the cover body 131b is covered on the side wall 112b of the first housing 11b, the second filter 16b and the first filter 15b may be exposed. Optionally, the filter cover 132b is rotatably connected to the cover body 131 b. For example, one side of the upper filter cover 132b is rotatably disposed on the inner wall of the cover body 131b surrounding the mounting hole 130b through a rotating shaft. The screen upper cover 132b may be opened by rotating the cover to close the mounting hole 130b or opening the mounting hole 130b so that the second screen 16b and the first screen 15b are exposed. Alternatively, the mounting hole 130b is disposed opposite to the communication hole 1211b, and the size of the mounting hole 130b is greater than or equal to the size of the communication hole 1211 b. Of course, in other embodiments, the size of the mounting hole 130b may be smaller than that of the communication hole 1211 b.

Further, the upper cover 132b can be engaged with the mounting hole 130b through a sealing member (as shown in fig. 4, but not labeled) with a shape corresponding to the mounting hole 130b, so as to improve the sealing effect of the dust box 10 and ensure the suction force of the dust suction opening 110 and the effective flow of the airflow inside the dust box 10.

The outlet 120 may be opened in the cover 13 b. Of course, when the second housing 12b is the same as the second housing 12 in the first exemplary structure of the dust box 10, the air outlet 120 may be opened in the second housing 12. Optionally, the cover 13 may further have a fastening hole.

In one embodiment, as shown in fig. 7, when the first screen 15b is partially received in the communication hole 1211b, the first screen 15b is inclined. For example, the first screen 15b may be inclined toward the air outlet 120, so that the air flow filtered by the first screen 15b can be quickly delivered to the air outlet 120. Specifically, an included angle between a side surface of the first filter 15b adjacent to the cover 13b and a side surface of the second casing 12b facing the cover 13b is greater than 90 ° and less than 180 °.

Optionally, a notch 1213b is formed at an edge of the second casing 12b away from the dust suction port 110, and a protrusion 1212b is disposed on a side of the second casing 12b facing the cover 13b, and the protrusion 1212b surrounds the notch 1213 b. The cover 13b has a mating groove (not shown) formed on a side facing the second housing 12b, the mating groove has a shape corresponding to the shape of the protrusion 1212b, and when the cover 13b covers the second housing 12b, the protrusion 1212b of the cover 13b can be inserted into the mating groove to separate the passage cavity 101 from the notch 1213 b. As shown in fig. 8, the first casing 11b has a first placement groove 1110b, and the first placement groove 1110b opens toward the cover 13b, corresponding to the notch 1213b of the second casing 12 b. When the second housing 12b is covered on the first housing 11b, the accommodating chamber 100 and the first placement groove 1110b are spaced from each other and do not communicate with each other.

With respect to the third exemplary construction of the dust box 10 described above, the dust box 10 may further be provided with a snap assembly 30 to facilitate the snap connection of the dust box 10 to other devices. Still another example of the snap assembly 30 of the dirt box assembly 1 can be described in detail below.

The latch assembly 30 may include a pressing portion 31b, a latch portion 321b protruding from the pressing portion 31b, and an elastic portion 33 b. The engaging portion 321b is for engaging with an engaging groove of the apparatus main body. The elastic portion 33b supports the pressing portion 31 b. Specifically, the pressing portion 31b is formed with a second placing groove 310b, and the shape of the pressing portion 31b is adapted to the shape of the notch 1213b, for example. The opening direction of the second placement groove 310b is opposite to the protruding direction of the catching portion 321 b. The elastic portion 33b is an elastic member such as a spring, for example, and one end of the elastic portion 33b extends into the second placement groove 310b and the other end thereof extends into the first placement groove 1110 b. When the first housing 11b, the second housing 12b, and the cover are assembled, the other end of the elastic portion 33b is supported in the first placing groove 1110b, thereby supporting the pressing portion 31b and the locking portion 321 b. The locking portion 321b corresponds to a locking hole of the cover 13 b. Optionally, two opposite side walls 112b in the first placement groove 1110b are provided with sliding grooves, two corresponding sides of the pressing portion 31b are provided with sliding rails, and the sliding rails are embedded into the sliding grooves, so that the pressing portion 31b can slide in the first placement groove 1110 b.

When the pressing portion 31b is not pressed, the elastic portion 33b is elastically supported between the first placing groove 1110b and the second placing groove 310b, and the pressing portion 31b is abutted so that the buckling portion 321b can protrude out of the buckling hole to be able to perform a buckling connection when assembled with the apparatus main body. When the pressing portion 31b is not pressed, the elastic portion 33b further elastically compresses, the pressing portion 31b can move toward the first housing 11b, for example, can move into the first placing groove 1110b, and the locking portion 321b moves away from the cover 13b along with the movement, so that the locking portion 321b does not protrude out of the locking hole of the cover 13b, and can be locked.

Taking a sweeping robot as an example, the sweeping robot (not shown) includes, for example, an apparatus main body (not shown) and the dust box assembly 1 of the embodiment, where the apparatus main body is used for sweeping, for example, a floor.

Specifically, for example, the apparatus main body includes a housing, a roll brush provided in the housing, and a drive motor that drives the roll brush to roll. The main body of the apparatus can be used in conjunction with the dust box assembly 1 of the present embodiment, for example, a housing of the main body of the apparatus is provided with a snap groove (not shown) for snap-coupling with the snap portions 321(321a, 321 b). Specifically, when the pressing portions 31(31a, 31b) are pressed, the elastic portions 33(33a, 33b) are elastically deformed, the pressing portions 31(31a, 31b) can drive the latching portions 321(321a, 321b) to move away from the latching grooves, so that the latching portions 321(321a, 321b) can be disengaged from the latching grooves, and when the pressing portions 31(31a, 31b) are not pressed, the elastic restoring force of the elastic portions 33(33a, 33b) can enable the pressing portions 31(31a, 31b) to drive the latching portions 321(321a, 321b) to move close to the latching grooves or keep a state close to the latching grooves, so that the latching portions 321(321a, 321b) can be latched with the latching grooves.

The present embodiment can facilitate the snap-fit connection with the device body of the cleaning device by providing the snap assembly 30. In some embodiments, the fastening assembly 30 includes two fastening portions 321(321a), so that the fastening connection between the dust box assembly 1 and the apparatus main body of the present embodiment can be tighter, the fixing effect of the two structures can be enhanced, and the arrangement of the two fastening portions 321(321a) can further limit the relative displacement between the dust box 10 and the housing of the apparatus main body, thereby ensuring the stability of the structures.

The attachment 22 of the dust suction assembly 20 of this embodiment may be fixed to the housing of the apparatus main body. The good fastening effect and the limiting effect of the fastening component 30 prevent the dust box 10 and the device body from shifting, so that the sealing effect of the connecting piece 22 and the air outlet 120 can be effectively ensured.

To further enhance the speed of the airflow and optimize the design of the structural space, the present embodiment provides an exemplary configuration of the connector 22 as follows:

referring to fig. 12, the connecting member 22 of the present embodiment may have an irregular shape. One side of the connection member 22 may be formed with a first vent 221, the first vent 221 for communicating with the outlet 120, and the other side of the connection member 22 is formed with a second vent 222 communicating with the first vent 221.
