[0002] In recent years, with the continuous development of smart home technology, it has provided great convenience for daily life. In particular, the gradual popularization of automatic cleaning robots has made home cleaning easier and more popular in the market. The cleaning function is the main function of the cleaning robot. Cleaning is usually combined with vacuuming to collect garbage on the ground in time and achieve floor cleaning.

[0038] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the present invention, the following is a detailed description of the specific implementation method, structure, characteristics and effects of a dust box proposed according to the present invention in combination with the accompanying drawings and preferred embodiments.

[0039] On the one hand, the utility model provides a dust box for a cleaning robot. The cleaning robot can also be called a self-cleaning device, a sweeper, a sweeping robot or a mopping machine, etc., which can automatically clean and collect debris without user operation. The cleaning robot can further include a machine body, a motion system, a cleaning system and a sensing system, etc. In order to enable the cleaning robot to adapt to more cleaning spaces and the body to be more stable and balanced, the machine body is usually flat and circular, or can also have other shapes, such as semicircular, square, etc. The sensing system is arranged on the machine body, and is used to sense walls and obstacles, draw maps, and determine the position when the machine body moves to clean, such as the sensing system includes a camera, a distance sensor, a collision sensor, a distance sensor, a magnetometer, an accelerometer, a gyroscope, an odometer and other sensing devices. The motion system may include a plurality of moving wheels and a driving member, and the moving wheel may include a left wheel and a right wheel, and the driving member may control the rotation of the left wheel and the right wheel respectively, so as to realize the movement of the machine body such as moving forward and backward and rotating left and right. In order to make the movement of the machine body more balanced, the moving wheel may also include a driven wheel, and the driven wheel may be a universal wheel, etc. The cleaning system may include only a sweeping system, or may include a sweeping system and a mopping system at the same time. The mopping system may include a support plate, a water tank, etc., which can be used for wet and dry mopping of the ground. The cleaning system includes a roller brush, a dust box and an exhaust fan. The roller brush is connected to the machine body through a driving member. The machine body has a dust suction port located behind the roller brush, and the dust box is located on the wind path between the exhaust fan and the dust suction port. The roller brush has a certain interference with the ground. During the rotation process, the roller brush can sweep up the garbage on the ground and roll it under the dust suction port, and then the gas generated by the exhaust fan to be sucked back to the dust box is sucked into the dust box.

[0040] The dust box provided in this application is Figure 1-6 As shown, including:

[0041] A dust box body (100), wherein a dust gas inlet (101) and an exhaust port (102) are provided on the dust box body (100), and the dust box body (100) comprises a bottom wall (111);

[0042] A filter screen (200) is connected to the dust box body (100), and the filter screen (200) is located between the dust inlet (101) and the exhaust port (102), the filter screen (200) is opposite to the bottom wall (111), the filter screen (200) is parallel to the bottom wall (111), and the air outlet direction of the filter screen (200) and the exhaust port (102) forms a preset angle.

[0043] The dust box body (100) is detachably connected to the machine body of the cleaning robot, and the dust box can be removed from the machine body to clean or replace the dust box. The machine body is provided with a storage space for installing the dust box, as well as a dust suction channel and an air outlet channel. The first end of the dust suction channel extends to the dust suction port, and the second end of the dust suction channel extends to the storage space to communicate with the storage space. The first end of the air outlet channel extends to the storage space, and the second end of the air outlet channel extends to connect with the exhaust fan. The dust box body (100) is detachably installed in the storage space, the dust and gas inlet (101) is connected to the dust suction channel, and is connected to the dust suction port of the machine body through the dust suction channel, and the exhaust port (102) is connected to the air outlet channel, and is connected to the exhaust fan through the air outlet channel. During the cleaning process, the exhaust fan drives the air to drive the debris from the dust suction port into the dust suction channel, and then enters the dust box body (100) through the dust gas inlet (101), and is filtered through the filter (200) to remove the debris. The airflow continues to be discharged through the exhaust port (102) and the air outlet channel, so that the cleaning debris is collected. For the convenience of description below, the length, width, height and direction, such as the horizontal direction, are described by taking the direction of the dust box body (100) when it is actually used as an example.

[0044] Since the main body of the machine is usually flat in shape, it is suitable for cleaning shorter spaces such as under a bed. In order to make full use of the space inside the main body of the machine, the exhaust fan and the dust box are usually arranged in the horizontal direction, and the air outlet channel extends nearly in the horizontal direction. The exhaust port (102) needs to adapt to the arrangement of the air outlet channel and the exhaust fan. The direction of the exhaust port (102) or the direction in which the gas is discharged from the exhaust port (102) can be at a certain angle to the horizontal direction. In order to adapt to the direction of the air outlet channel, the angle will not be very large, such as an angle of less than 30 degrees. For example, the direction of the exhaust port (102) or the direction in which the gas is discharged from the exhaust port (102) can be horizontal, such as Figure 5 The direction indicated by the middle arrow is the air outlet direction at the exhaust port (102).

[0045] In a more specific embodiment, the dust box body (100) further includes a top wall (121) opposite to the bottom wall (111), the dust box body (100) includes an inner cavity, the filter (200) is located in the inner cavity and between the top wall (121) and the bottom wall (111), the filter (200) divides the inner cavity into a dust cavity (103) and an exhaust channel (104) located on both sides of the filter (200), the dust and gas inlet (101) is connected to the dust cavity (103), the exhaust port (102) is connected to the exhaust channel (104), the dust cavity (103) and the exhaust channel (104) only interact with each other through the filter (200), so that all debris in the airflow can be blocked by the filter (200) and retained in the dust cavity (103). The filter (200) and the air outlet direction at the exhaust port (102) are at a preset angle. On the one hand, the extension area of ​​the filter (200) is not limited by the length or width of the horizontal extension of the dust box body (100), so that the filter (200) has a larger filtering and ventilation area, thereby improving the dust removal efficiency; on the other hand, the top wall (121) of the dust box body (100) is usually extended horizontally to adapt to the structure of the machine body. The filter (200) is tilted, which will increase the space between the filter (200) and the top wall (121) of the dust box body (100). Then, after the airflow passes through the filter (200), the resistance of the top wall (121) is small, thereby reducing the wind resistance of the airflow, making the air flow faster and the dust collection effect better.

[0046] like Figure 1-3 As shown, the dust box body (100) is an irregular approximately rectangular parallelepiped structure, the extension of the dust box body (100) in the length direction X is greater than the extension in the width direction Y, and the exhaust port (102) is arranged on the side wall on one side in the width direction Y, in order to increase the opening size of the exhaust port (102). The filter (200) can be tilted to achieve the tilt due to the different heights of the two ends in the length direction X, or it can be tilted to achieve the tilt due to the different heights of the two ends in the width direction Y. At the same tilt angle, the tilt in the width direction Y will enable the filter (200) to obtain a larger filtering area, and make the exhaust channel (104) wider in the direction close to the exhaust port (102), which will make the exhaust smoother.

[0047] The bottom wall (111) and the top wall (121) of a conventional dust box are usually parallel and both are arranged horizontally. However, due to the inclination of the filter (200), one side is close to the bottom wall (111), which reduces the distance between the filter (200) and the bottom wall (111), resulting in a reduction in the space for the dust box to accommodate debris. In the present embodiment, the bottom wall (111) is parallel to the filter (200), that is, the bottom wall (111) is arranged to be inclined relative to the horizontal direction, so as to overcome the reduction in the space of the dust chamber (103) caused by the inclination of the filter (200), and after the debris is blocked by the filter (200) and falls onto the bottom wall (111), the accumulation manner will also follow the inclination trend of the bottom wall. The bottom wall (111) is arranged to be parallel to the filter (200) rather than simply inclined, so that the accumulated debris is not easy to cover the lowest point of the filter (200), and only when the dust chamber (103) is about to be filled, will it contact the filter (200) more evenly over the entire area of ​​the filter (200), thereby ensuring the effective use of the space of the dust chamber (103) and the filter (200) can always work with a high filtering efficiency.

[0048] The dust box and cleaning robot proposed in the embodiment of the utility model can increase the filter area and reduce the wind resistance at the dust box outlet by tilting the filter, and increase the space for accommodating debris in the dust box by setting the bottom wall of the dust box parallel to the filter. In the related art, the filter is placed horizontally, and the area is small due to the restriction of the width of the dust box, and the ventilation efficiency is low. The increase in the space between the filter and the top surface of the dust box and the space for stagnant debris in the dust box cannot be taken into account, resulting in a decrease in space utilization. In the technical solution of the present application, the area of ​​the filter is not restricted by the width of the dust box by tilting the filter relative to the air outlet direction of the exhaust port, so that the area of ​​the filter is increased, and the distance between the filter and the top surface of the dust box is increased, so that the wind resistance on one side of the exhaust port is reduced, so that the airflow can be smoother. At the same time, by setting the filter parallel to the bottom wall, the tilt of the filter will not affect the size of the dust collection space of the dust box, and then effectively utilize the space, and avoid the lower end of the filter being easily covered by debris due to the tilted setting of the filter.

[0049] In one embodiment, if Figure 5 As shown, the preset angle a is less than 60 degrees, so as to avoid the excessive tilting of the bottom wall (111) due to an angle that is too large, which leads to a waste of space due to a large difference in the overall shape of the machine body, and to avoid the problem that the filter (200) is too tilted and the lower end is too low, which is easily submerged by the debris in the dust chamber (103), resulting in a decrease in filtering efficiency. The preset angle a is greater than 10 degrees, which ensures the area of ​​the filter (200) and allows the exhaust channel (104) to have enough space at the exhaust port (102) to ensure smooth airflow.

[0050] In one embodiment, the distance between the end of the filter (200) away from the exhaust port (102) and the top wall (121) is less than a preset distance or abuts against each other, so as to ensure that there is enough space in the dust chamber (103). According to different inclination modes of the filter (200), there can be multiple settings between the filter (200) and the top wall (121). For example, in one embodiment, the filter (200) is inclined in a direction close to the exhaust port (102) and in a direction away from the bottom wall (111), and the preset distance is sufficient to ensure that the end of the filter (200) close to the exhaust port (102) does not block the exhaust port (102). Alternatively, in one embodiment, the dust inlet (101) and the exhaust port (102) are respectively located on opposite sides of the dust box body (100), so that the airflow flows from one side of the dust box body (100) to the other side, and the airflow does not turn at a large angle in the dust box body (100), so that the wind resistance is small and the airflow is smooth. The filter (200) is inclined in the direction close to the exhaust port (102) and in the direction close to the bottom wall (111). On the one hand, the angle between the airflow and the filter (200) is increased, which helps to smoothly pass through the filter (200); on the other hand, the distance between the end of the filter (200) away from the exhaust port (102) and the top wall (121) can be very small, such as abutting against the top wall (121), thereby ensuring the area of ​​the exhaust channel (104) at the exhaust port (102), ensuring the airflow circulation speed, and ensuring that the dust chamber (103) has a large space. If the filter (200) does not abut against the top wall (121), the preset distance between the filter (200) and the top wall (121) can be less than 1 cm, such as 0.5 cm.

[0051] In one embodiment, the dust box body (100) further comprises a surrounding wall, which is connected to the bottom wall (111) and extends to one side of the bottom wall (111), and the bottom wall (111) surrounds the bottom wall (111). The surrounding wall comprises a first sub-surrounding wall (112) and a second sub-surrounding wall (113) which are arranged opposite to each other, the second sub-surrounding wall (113) and the exhaust port (102) are located on the same side of the dust box body (100), and the first sub-surrounding wall (112) is inclined in a direction close to the bottom wall (111) toward a direction close to the second sub-surrounding wall (113). The dust gas inlet (101) is provided on the first sub-surrounding wall (112).

[0052] The second sub-wall (113) can extend in the vertical direction, and the first sub-wall (112) is inclined in the vertical downward direction toward the second sub-wall (113), so that the dust inlet (101) is inclined toward the filter (200) and the exhaust port (102), so that the airflow entering the dust box body (100) from the dust inlet (101) is inclined toward the filter (200) side, so that the airflow flows more directly to the filter (200), reducing the airflow directed to the second sub-wall (113), thereby reducing wind resistance.

[0053] In one embodiment, the dust box body (100) includes a dust box shell (110) and a filter support (120), the dust box shell (110) includes the aforementioned bottom wall (111) and surrounding wall, the dust box shell (110) is provided with a dust gas inlet (101), and the filter support (120) is provided with an exhaust port (102). The dust box shell (110) is also provided with a top opening (105) opposite to the bottom wall (111), the filter (200) is detachably connected to the filter support (120), the filter support (120) is detachably connected to the dust box shell (110), and the filter (200) covers the top opening (105).

[0054] By disassembling the filter support (120) and the filter (200), the top opening (105) can be opened and closed, and the dust chamber (103) can be cleaned, and the filter (200) can be cleaned and replaced through the top opening (105). The opening area of ​​the top opening (105) can be consistent with the area of ​​the filter area on the filter (200), or slightly smaller than the area of ​​the filter area. The filter area refers to the area on the filter (200) that is air-permeable and filterable, such as filter cotton. There can be multiple ways of detachable connection, which can be one or a combination of snap-on, adhesive, magnetic connection, hanging, plug-in and clamping connection.

[0055] In one embodiment, the filter screen support (120) comprises a top wall (121) and a support side wall (122), the support side wall (122) is connected to the top wall (121) and extends to one side of the top wall (121), and the exhaust port (102) is provided on the support side wall (122). The filter screen (200) is connected to the support side wall (122), and the filter screen (200) is arranged obliquely relative to the top wall (121).

[0056] After the filter support (120) is connected to the dust box housing (110), the top wall (121) is approximately horizontal, and the filter (200) is tilted relative to the top wall (121), so that the filter (200) is tilted relative to the horizontal plane. For example, the distance between the filter (200) and the top wall (121) can be reduced in a direction away from the exhaust port (102), and the filter can be in contact with the top wall (121) at one end away from the exhaust port (102), so as to achieve the advantages of the embodiment in which the filter (200) is tilted in a direction close to the exhaust port (102) and in a direction close to the bottom wall (111) as in the aforementioned embodiment, which will not be described in detail here.

[0057] Furthermore, a hand-held portion (123) is provided on the filter support (120), and the hand-held portion (123) is used to apply external force to move the dust box.

[0058] The hand-held portion (123) can be formed by a depression of the top wall (121) toward one side of the filter (200), and the depression direction of the hand-held portion (123) is inclined toward one side, and the length of the depression can be slightly larger than the length of four fingers put together, and then the user can insert four fingers into the hand-held portion (123) and move the dust box by lifting it through the depressed side wall, which can achieve convenient force application, and the depression will not occupy the internal space of the cleaning robot.

[0059] In one embodiment, the dust box further comprises at least one sealing member (300). The sealing member (300) can be used for sealing between the filter (200) and the dust box housing (110), such as the sealing member (300) can be connected to the filter (200), such as being connected to a circle near the edge of the lower surface of the filter (200), and after the filter (200) is installed in place, the sealing member (300) abuts against the edge of the top opening (105). Alternatively, the sealing member (300) abuts against the dust box housing (110) at the periphery of the top opening (105), thereby sealing the dust chamber (103) and preventing dust leakage. Alternatively, the sealing member (300) can also be connected to the dust box housing (110), such as being arranged around the top opening (105), and after the filter (200) is installed in place, the sealing member (300) abuts against the bottom surface of the filter (200), thereby also achieving sealing. In addition, the seal (300) can also be used to seal between the filter (200) and the filter support (120), such as the seal (300) is connected to the filter (200), and the seal (300) is in contact with the filter support (120). Alternatively, the seal (300) is connected to the filter support (120), and the seal (300) is in contact with the filter (200), so as to achieve sealing of the exhaust passage (104), avoid gas leakage, and ensure the intake air flow rate.

[0062] The mounting groove (106) is located on the upper wall of the dust box housing (110) opposite to the bottom wall (111), and the filter (200) and the filter support (120) can be completely embedded in the mounting groove (106), so that the upper wall of the dust box housing (110) and the top wall (121) of the filter support (120) are approximately located in the same plane, thereby expanding the volume of the dust chamber (103) and making the overall appearance of the dust box more regular and simple. The inclination angle of the groove bottom is consistent with the inclination angle of the filter (200), so that the filter (200) can abut against the bottom surface of the groove. As in the aforementioned embodiment including the sealing member (300), the groove bottom will abut against the sealing member (300) in the circumferential direction of the top opening (105), playing the role of supporting the filter (200) and sealing.

[0063] In one embodiment, the dust box housing (110) comprises a bottom shell and an upper cover (114), the bottom shell comprises a bottom wall (111) and a surrounding wall, the surrounding wall is connected to the bottom wall (111) and extends to one side of the bottom wall (111), a dust gas inlet (101) is provided on the surrounding wall, and the surrounding wall encloses a mounting opening opposite to the bottom wall (111). A top opening (105) is provided on the upper cover (114), and the upper cover (114) is connected to the surrounding wall and covers the mounting opening.

[0064] The dust box housing (110) is a hollow structure, which cooperates with the filter (200) to enclose the dust chamber (103), and the aforementioned embodiment including the mounting groove (106) makes the structure of the dust box housing (110) relatively complicated. In order to facilitate the processing of the dust box housing (110), the structure of the dust box housing (110) is divided into a bottom shell and an upper cover (114), and the mounting groove (106) and the top opening (105) are processed on the upper cover (114), so that the processing is simpler. The bottom shell and the upper cover (114) can be directly ultrasonically sealed and welded to ensure airtightness and connection strength. Alternatively, a detachable connection can be adopted, and then the bottom shell can be disassembled and cleaned.

[0065] In combination with the above-mentioned specific structure, an implementation method of clamping the filter screen (200) and the filter screen support (120) is provided below, aiming to improve the connection strength and facilitate disassembly. Figure 4 , Figure 6As shown, the filter (200) includes a first clamp, the filter support (120) includes a second clamp, and the filter (200) is detachably clamped with the filter support (120) through the action of the first clamp and the second clamp. The first clamp may include a plug-in clamp (210) and at least one first static clamp (220) located on both sides of the length direction of the filter (200), and the plug-in clamp (210) includes a first spring plate, a first spring clamp and a second spring clamp. The second clamp includes a socket (126) corresponding to the plug-in clamp (210), and a first clamping groove corresponding to the first spring clamp located on the inner wall of the filter support (120), such as the side wall (122) of the support, and at least one second clamping groove corresponding to the first static clamp (220). The first spring plate is used to pass through the socket (126), the first spring clamp is clamped on the edge of the bracket side wall (122) opposite to the top wall (121), and the second spring clamp is embedded in the first slot. The first static clamp (220) is embedded in the second slot. The first spring plate can be elastic under the action of external force. When the filter (200) is disassembled, the first spring plate can be manually pushed and pulled, so that the first spring clamp and the second spring clamp are separated from the bracket side wall (122), and the filter (200) can be moved, so that the first static clamp (220) is out of the second slot, and disassembly is achieved. The first spring clamp is clamped on the edge of the bracket side wall (122) opposite to the top wall (121). After the filter bracket (120) is installed in place, the bracket side wall (122) and the dust box shell (110) cooperate to clamp the first spring clamp, so that the position of the filter (200) is more stable.

[0066] The following also provides an implementation method of snap-fitting the filter support (120) to the dust box housing (110), or in other words, a snap-fitting method of the filter support (120) to the groove wall of the mounting groove (106) in the dust box housing (110). The filter support (120) includes a third snap-fitting member, and the dust box housing (110) includes a fourth snap-fitting member (115). The filter support (120) is snap-fitted to the dust box housing (110) in a detachable manner through the action of the third snap-fitting member and the fourth snap-fitting member (115). Figure 4 , Figure 6As shown, the third clamp includes an elastic clamp (124) and at least one second static clamp (125) located on both sides of the filter support (120) in the length direction, and the elastic clamp (124) includes a second elastic plate and a third elastic clamp. The fourth clamp (115) includes a third clamping groove corresponding to the elastic clamp (124) and a fourth clamping groove corresponding to the second static clamp (125). The first elastic plate is used to elastically move so that the third elastic clamp is embedded in the third clamping groove. The second static clamp (125) is used to embed in the fourth clamping groove. The second elastic plate can be elastic under the action of external force. When the filter support (120) is disassembled, the filter support (120) can be manually pushed and pulled, and then the third elastic clamp interacts with the third clamping groove, so that the second elastic plate is deformed, and then the third elastic clamp is separated from the third clamping groove, so as to achieve disassembly.

[0067] Furthermore, in the embodiment in which the upper wall of the dust box shell (110) and the top wall (121) of the filter bracket (120) are approximately located in the same plane, a disassembly groove (109) connected to the installation groove (106) is also provided on the dust box shell (110), and the disassembly groove (109) corresponds to the elastic clamp (124), and then a hand can be inserted into the disassembly groove (109), so as to facilitate the application of external force to the filter bracket (120).

[0068] In one embodiment, a dust outlet (107) and an air inlet (108) are further provided on the dust box shell (110), the dust outlet (107) and the air inlet (108) are arranged opposite to each other, the bottom wall (111) is inclined in a direction away from the filter (200) from the first end to the second end, and the dust outlet (107) is arranged close to the second end of the bottom wall (111).

[0069] The machine body of the cleaning robot is also provided with a dust outlet, and the interior of the machine body is provided with a dust discharge channel connecting the storage space of the dust box and the dust outlet. After the dust box is placed in the storage space, the dust outlet (107) will be opposite to the dust discharge channel. The dust outlet is used to dock with the dust discharge mechanism of the base station after the cleaning robot moves to the base station. The dust discharge mechanism will provide a back-drawing power, and the airflow will enter the dust chamber (103) from the air inlet (108) of the dust box, and then push the debris in the dust chamber (103) through the dust outlet (107), the dust discharge channel and the dust outlet, and then flow into the storage component of the base station, thereby realizing the automatic removal of the debris in the dust box. Since the bottom wall (111) is inclined, debris will accumulate at the lower end of the bottom wall (111). During the process of discharging the debris, the debris will continuously converge toward the lower end of the bottom wall (111). The dust outlet (107) is arranged close to the second end of the bottom wall (111), that is, the dust outlet (107) is arranged close to the lower end of the bottom wall (111), so that the debris on the bottom wall (111) can be removed more thoroughly.

[0070] In addition, in the aforementioned dust box body (100) further including a surrounding wall, the surrounding wall including a first sub-wall (112) and a second sub-wall (113) arranged opposite to each other, the surrounding wall also includes a third sub-wall and a fourth sub-wall arranged opposite to each other, the first sub-wall (112), the third sub-wall, the second sub-wall (113) and the fourth sub-wall are sequentially connected in a surrounding manner, the dust outlet (107) is arranged on the third sub-wall, the air inlet (108) is arranged on the fourth sub-wall, and the third sub-wall and the fourth sub-wall are distributed in the length direction X of the dust box, so that the dust and gas inlet (101) arranged on the first sub-wall (112) can be opened large enough, and when exhausting dust, the airflow between the dust outlet (107) and the air inlet (108) can cover the entire area of ​​the width direction Y of the dust chamber (103) as much as possible, so as to ensure that the debris is blown out more thoroughly.

[0071] Furthermore, one-way openable and closable baffles are provided at the dust outlet (107), the air inlet (108) and the dust inlet (101). For example, when the dust inlet (101) is provided with an airflow that flows from the outside of the dust chamber (103) to the inside, the airflow will push the open baffle to prevent the leakage of debris.

[0072] On the other hand, the utility model also provides a cleaning robot, comprising any of the dust box described above, and a robot body, wherein the dust box is arranged on the robot body. The cleaning robot includes the advantages of any of the described embodiments, which will not be repeated here.
