Description

Dust box and cleaning robot

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on March 8, 2024, with application number 202420451811.2, and invention name “A dust box and cleaning robot”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of smart home technology, and in particular to a dust box and a cleaning robot. Background Art

[0003] In recent years, the continuous development of smart home technology has brought significant convenience to daily life. The increasing popularity of automatic cleaning robots, in particular, has made household cleaning increasingly easier and has gained market favor. Sweeping is the primary function of cleaning robots, often combined with vacuuming to promptly collect floor debris and achieve a clean floor. Vacuuming relies on the robot's internal fan and dust box. The fan drives airflow through an opening at the bottom of the robot, filtering it through the filter inside the dust box, trapping debris within.

[0004] The inventors realized that in existing dust boxes, the setting of the filter screen usually cannot achieve a good filtering effect and ensure the accumulation space of debris. Therefore, how to reasonably set the filter screen has become an urgent problem to be solved.

[0005] Application Contents

[0006] The present application provides a dust box and a cleaning robot, which increase the exhaust efficiency, reduce the wind resistance, and ensure the debris holding capacity of the dust box by tilting the filter and making the filter parallel to the bottom wall.

[0007] In one aspect, the present application provides a dust box for a cleaning robot, the dust box comprising:

[0008] A dust box body (100), the dust box body (100) is provided with a dust gas inlet (101) and an exhaust port (102), and the dust box body (100) includes a bottom wall (111);

[0009] The filter screen (200) is arranged to be inclined with respect to the horizontal plane, the filter screen (200) is connected to the dust box body (100), and the filter screen (200) is located between the dust and gas 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.

[0010] On the other hand, the present application 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. Beneficial effects

[0011] The dust box and cleaning robot proposed in this application can increase the filter area and reduce the wind resistance at the dust box outlet by setting the filter screen in an inclined manner. By setting the bottom wall of the dust box parallel to the filter screen, the space for accommodating debris in the dust box is increased. In the related art, the setting of the filter screen usually cannot take into account both good filtering effect and the space for debris accumulation. Therefore, how to reasonably set the filter screen has become an urgent problem to be solved. In the technical solution of this application, by tilting the filter screen relative to the air outlet direction of the exhaust port, the area of ​​the filter screen is not restricted by the width of the dust box, thereby increasing the area of ​​the filter screen and increasing the distance between the filter screen and the top surface of the dust box, thereby reducing the wind resistance on one side of the exhaust port and allowing the air flow to flow more smoothly. At the same time, by setting the filter screen parallel to the bottom wall, the tilting of the filter screen will not affect the size of the dust collection space of the dust box, thereby effectively utilizing the space and preventing the lower end of the filter screen from being easily covered by debris due to the tilted setting.

[0019] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined utility model purpose, the following is a detailed description of the specific implementation method, structure, characteristics and effects of a dust box proposed in the present application in combination with the accompanying drawings and preferred embodiments.

[0020] On the one hand, the present application 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 mop, 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. In order to enable the cleaning robot to adapt to more cleaning spaces and make the body more stable and balanced, the machine body is usually flat and round, or it can also have other shapes, such as semicircular, square, etc. The sensing system is set on the machine body and is used to sense walls and obstacles, draw maps, and determine the position of the machine body when it moves to clean. For example, 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 multiple moving wheels and a drive member. The moving wheels may include a left wheel and a right wheel. The drive member can control the rotation of the left and right wheels respectively, so that the machine body can move forward and backward and rotate left and right. In order to make the movement of the machine body more balanced, the moving wheel may also include a driven wheel, which may be a universal wheel, etc. The cleaning system may include only a sweeping system, or may include both a sweeping system and a mopping system. 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 in the air path between the exhaust fan and the dust suction port. The roller brush has a certain interference with the ground. During rotation, the roller brush can sweep up the garbage on the ground and roll it to the bottom of the dust suction port, and then the gas generated by the exhaust fan and drawn back to the dust box is sucked into the dust box.

[0021] The dust box provided in this application, as shown in Figures 1-6, includes:

[0022] A dust box body (100), the dust box body (100) is provided with a dust gas inlet (101) and an exhaust port (102), and the dust box body (100) includes a bottom wall (111);

[0023] The 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.

[0024] 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 carry the debris from the dust suction port into the dust suction channel, and then enters the dust box body (100) through the dust air inlet (101), and is filtered by the filter (200), removing the debris. The air flow continues to be discharged through the exhaust port (102) and the air outlet channel, thus achieving the collection of the cleaned debris. For the convenience of description below, the length, width, height and direction of the dust box body (100) in actual use are used as an example.

[0025] Since the main body of the machine is usually flat, it is suitable for cleaning shorter spaces such as under a bed. In order to fully utilize the space inside the main body of the machine, the exhaust fan and the dust box are usually arranged in a horizontal direction, and the air outlet channel extends in a nearly 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 of the gas discharged from the exhaust port (102) can be at a certain angle to the horizontal direction. To adapt to the direction of the air outlet channel, the angle will not be too large, such as an angle of less than 30 degrees. For example, the direction of the exhaust port (102) or the direction of the gas discharged from the exhaust port (102) can be horizontal. The direction indicated by the arrow in FIG5 is the air outlet direction at the exhaust port (102).

[0026] 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 is located 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), and the exhaust port (102) is connected to the exhaust channel (104), and 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 from the top wall (121) is small, which reduces the wind resistance of the airflow, makes the air flow faster, and improves the dust collection effect.

[0027] As shown in Figures 1-3, the dust box body (100) has an irregular, approximately rectangular parallelepiped structure. The extension of the dust box body (100) in the longitudinal direction X is greater than the extension in the width direction Y. The exhaust port (102) is provided 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 so that the two ends in the longitudinal direction X have different heights, or the two ends in the width direction Y have different heights. Under 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.

[0028] The bottom wall (111) and the top wall (121) of a conventional dust box are usually parallel and are both 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 this embodiment, the bottom wall (111) is parallel to the filter (200), that is, the bottom wall (111) is tilted relative to the horizontal direction, which overcomes the reduction in the space of the dust chamber (103) caused by the tilt of the filter (200), and after the debris is blocked by the filter (200) and falls onto the bottom wall (111), the accumulation pattern will also follow the tilt trend of the bottom wall. The bottom wall (111) is set to be parallel to the filter (200) rather than simply tilted, so that the debris accumulation 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.

[0029] The dust box and cleaning robot proposed in the embodiments of the present application increase the filter area and reduce wind resistance at the dust box outlet by tilting the filter. The parallel arrangement of the dust box bottom wall and the filter increases the space within the dust box to accommodate debris. In related art, the filter is placed horizontally, which is limited by the width of the dust box and results in a small area, low ventilation efficiency, and a conflict between increasing the space between the filter and the top surface of the dust box and ensuring space for debris to accumulate within the dust box, resulting in reduced space utilization. In the technical solution of the present application, by tilting the filter relative to the air outlet, the filter area is not restricted by the width of the dust box, thereby increasing the filter area. The distance between the filter and the top surface of the dust box is increased, reducing wind resistance on the exhaust side and ensuring smoother airflow. Furthermore, by arranging the filter parallel to the bottom wall, the tilt of the filter does not affect the size of the dust box's dust collection space, thereby effectively utilizing the space and preventing debris from obstructing the lower end of the filter due to the tilted filter.

[0030] In one embodiment, as shown in FIG5 , the preset angle a is less than 60 degrees to avoid excessive tilting of the bottom wall (111) due to an excessively large angle, which would result in wasted space due to a large difference from the overall shape of the machine body, and to avoid the problem that the filter (200) is tilted too much, resulting in the lower end being too low and easily being partially submerged by debris in the dust chamber (103), resulting in a decrease in filtration efficiency. The preset angle a is greater than 10 degrees to ensure the area of ​​the filter (200) and to ensure that there is sufficient space in the exhaust channel (104) at the exhaust port (102) for smooth airflow.

[0031] 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, ensuring that there is enough space in the dust chamber (103). Depending on the different tilting 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 tilted in a direction close to the exhaust port (102) and 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 speed, and ensuring a large space in the dust chamber (103). 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.

[0032] In one embodiment, the dust box body (100) further includes 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 includes a first sub-wall (112) and a second sub-wall (113) that are arranged opposite to each other, the second sub-wall (113) and the exhaust port (102) are located on the same side of the dust box body (100), and the first sub-wall (112) is inclined in a direction close to the bottom wall (111) toward a direction close to the second sub-wall (113). The dust gas inlet (101) is opened on the first sub-wall (112).

[0033] 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.

[0034] In one embodiment, the dust box body (100) includes a dust box housing (110) and a filter holder (120), the dust box housing (110) includes the aforementioned bottom wall (111) and a surrounding wall, the dust box housing (110) is provided with a dust inlet (101), and the filter holder (120) is provided with an exhaust port (102). The dust box housing (110) is further provided with a top opening (105) opposite to the bottom wall (111), the filter (200) is detachably connected to the filter holder (120), the filter holder (120) is detachably connected to the dust box housing (110), and the filter (200) covers the top opening (105).

[0035] By disassembling the filter holder (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 are many ways to connect the filter, which can be one or a combination of snap-on, adhesive, magnetic connection, hanging, plug-in and clamping connection.

[0036] In one embodiment, the filter screen support (120) includes a top wall (121) and a support side wall (122), the support side wall (122) is connected to the top wall (121) and extends toward 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).

[0037] After the filter holder (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 the direction away from the exhaust port (102), and the filter can be abutted against 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 the direction close to the exhaust port (102) and toward the bottom wall (111) in the direction close to the exhaust port (102) as in the aforementioned embodiment, which will not be repeated here.

[0038] Furthermore, a hand-held portion (123) is provided on the filter bracket (120), and the hand-held portion (123) is used to apply external force to move the dust box.

[0039] The hand-held portion (123) can be formed by being recessed by the top wall (121) toward one side of the filter (200), and the recessed direction of the hand-held portion (123) is inclined toward one side, and the length of the recess can be slightly greater than the length of four fingers put together, so that the user can insert four fingers into the hand-held portion (123) and move the dust box by lifting it through the recessed side wall, thereby achieving convenient force application, and the recessed form does not occupy the internal space of the cleaning robot.

[0040] 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 around the lower surface of the filter (200) near the edge, 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 outer periphery of the top opening (105), thereby sealing the dust chamber (103) and preventing dust leakage. Alternatively, the sealing member (300) can 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 bracket (120), such as the seal (300) is connected to the filter (200), and the seal (300) is in contact with the filter bracket (120). Alternatively, the seal (300) is connected to the filter bracket (120), and the seal (300) is in contact with the filter (200), thereby achieving sealing of the exhaust channel (104), avoiding gas leakage, and ensuring the intake flow rate.

[0041] The sealing member (300) may be foam, soft rubber, etc.

[0042] In one embodiment, a mounting groove (106) is provided on the dust box housing (110), the mounting groove (106) includes an inclined groove bottom, a top opening (105) is provided at the groove bottom, and the filter (200) and the filter bracket (120) are at least partially embedded in the mounting groove (106).

[0043] The mounting groove (106) is located on the upper wall of the dust box housing (110) opposite to the bottom wall (111). The filter (200) and the filter holder (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 holder (120) are approximately located on 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 embodiment including the sealing member (300) described above, 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.

[0044] In one embodiment, the dust box housing (110) includes a bottom shell and an upper cover (114), the bottom shell includes 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 inlet (101) is provided on the surrounding wall, and the surrounding wall encloses a mounting opening opposite to the bottom wall (111). The upper cover (114) is provided with a top opening (105), and the upper cover (114) is connected to the surrounding wall and covers the mounting opening.

[0045] The dust box housing (110) is a hollow structure, which cooperates with the filter (200) to enclose the dust chamber (103). The aforementioned embodiment including the mounting groove (106) makes the structure of the dust box housing (110) relatively complex. 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). The mounting groove (106) and the top opening (105) are processed on the upper cover (114), making the processing 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.

[0046] In combination with the above-mentioned specific structure, an embodiment of the clamping connection between the filter screen (200) and the filter screen support (120) is provided below, aiming to improve the connection strength and facilitate disassembly. As shown in Figures 4 and 6, the filter screen (200) includes a first clamping member, and the filter screen support (120) includes a second clamping member. The filter screen (200) is detachably clamped to the filter screen support (120) through the action of the first clamping member and the second clamping member. The first clamping member may include a plug-in clamping member (210) and at least one first static clamping head (220) located on both sides of the length direction of the filter screen (200). The plug-in clamping member (210) includes a first elastic plate, a first elastic clamping head, and a second elastic clamping head. The second clamping member includes a socket (126) corresponding to the plug-in clamping member (210), and a first clamping groove corresponding to the first elastic clamping head located on the inner wall of the filter screen support (120), such as the side wall (122) of the support, and at least one second clamping groove corresponding to the first static clamping head (220). The first spring plate is used to pass through the socket (126), the first spring clamp is stuck 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 removed, the first spring plate can be manually pushed and pulled, thereby causing the first spring clamp and the second spring clamp to be disengaged from the bracket side wall (122), and then 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 stuck 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.

[0047] The following also provides an embodiment of the clamping connection between the filter holder (120) and the dust box housing (110), or in other words, a clamping connection method between the filter holder (120) and the groove wall of the mounting groove (106) in the dust box housing (110). The filter holder (120) includes a third clamping member, and the dust box housing (110) includes a fourth clamping member (115). The filter holder (120) is detachably clamped to the dust box housing (110) through the action of the third clamping member and the fourth clamping member (115). As shown in Figures 4 and 6, the third clamping member includes an elastic clamping member (124) and at least one second static clamping head (125) located on both sides of the length direction of the filter holder (120). The elastic clamping member (124) includes a second elastic plate and a third elastic clamping head. The fourth clamping member (115) includes a third clamping slot corresponding to the elastic clamping member (124) and a fourth clamping slot corresponding to the second static clamping head (125). The first elastic plate is used to elastically elasticate the third elastic clamping head so as to be embedded in the third clamping slot. The second static clamping head (125) is used to be embedded in the fourth clamping slot. The second elastic plate can be elasticated under the action of an external force. When the filter bracket (120) is disassembled, the filter bracket (120) can be manually pushed and pulled, thereby causing the third elastic clamping head to interact with the third clamping slot, causing the second elastic plate to deform, and then the third elastic clamping head is separated from the third clamping slot, thereby achieving disassembly.
