Description

Technical Field

[0001] The present application relates to the field of sweeping robots, and in particular to a dust box, a cleaning robot and a cleaning device. Background Art

[0002] As people's living standards continue to improve, more and more people advocate freeing their hands, and the demand for automatic integrated sweeping robots is becoming more and more urgent. During the operation of sweeping machines, they often encounter complex environments with impurities such as kitchen waste, domestic waste, small debris, paper, hair, etc. Long-term use will produce a relatively large number of bacteria, which will emit unpleasant odors and affect the equipment and health. Therefore, it is necessary to clean the dust box in time. In the relevant technology, the sweeping robot can be docked with a base station, and the base station collects the contents of the dust box of the sweeping robot to realize the function of automatic dust collection. For sweeping robots with automatic integration functions, in the relevant technology, the dust box with automatic dust collection function has a complex structure and high cost. When collecting dust, the garbage in the dust box is driven by the airflow to separate from the dust box and enter the base station. Due to inertia or large intermediate flow, the garbage will go to the other end, which easily forms a dead corner of airflow in the dust box, and the dust collection is not clean.

[0054] like Figure 4 The figure shows a cleaning device provided in an embodiment of the present application, which includes a cleaning robot 200 and a base station 300. The cleaning robot 200 can clean the ground, etc. The cleaning robot 200 includes a shell 210. The shell 210 includes a peripheral shell, a top cover and a bottom cover. The top cover is arranged on the upper side of the peripheral shell, and the bottom cover is arranged on the lower side of the peripheral shell.

[0055] like Figure 4As shown, a cleaning robot 200 provided in an embodiment of the present application also includes a walking device, a middle sweeping device 220, a dust box 100, a fan 230, etc. The walking device includes two rollers and a universal wheel arranged on the bottom cover, and the rollers and the universal wheel are arranged in a triangle. The cleaning robot 200 moves on the ground through the walking device. The dust box 100 is provided with a first air vent 1b and an air outlet 1d, and the fan 230 is provided corresponding to the air outlet 1d of the dust box 100; wherein, a filter element 16 is provided at the air outlet 1d of the dust box 100; wherein, the middle sweeping device 220 includes a middle sweeping cover 221 and a middle sweeping roller brush 222, and the middle sweeping cover 221 is provided at the bottom of the shell 210, and cooperates with the shell 210 to enclose a middle sweeping cavity 220a; the middle sweeping roller brush 222 is rotatably connected to the shell 210 and is located in the middle sweeping cavity 220a; the cleaning robot 200 performs cleaning work When the fan 230 is started, the airflow direction in the cleaning robot 200 is as follows: the external airflow passes through the middle sweeping chamber 220a and then enters the accommodating chamber 1a from the first vent 1b, and then is filtered by the filter element 16 provided at the air outlet 1d and discharged from the air outlet 1d to the fan 230, that is, the dust suction effect of the cleaning robot 200 is achieved through the fan 230, wherein the middle sweeping roller brush 222 rotates forward when the cleaning robot 200 performs cleaning work, and the middle sweeping roller brush 222 sweeps the ground and brings the garbage into the dust box 100.

[0056] like Figure 4 As shown, the base station 300 is provided with a docking station 330, which is provided with a dust collection port 310 and dust collection channels 320, 320. The dust collection port 310 is connected to the dust collection channels 320, 320. The middle sweeping chamber 220a of the cleaning robot 200 is arranged corresponding to the dust collection port 310. The base station 300 is also provided with a dust collection bag and a dust collection fan. During automatic dust collection, the cleaning robot 200 moves to the docking station 330 and connects the middle sweeping chamber 220a to the dust collection port 310. Then, the dust collection fan of the base station 300 is started. At this time, the airflow direction is from the accommodating chamber 1a to the middle sweeping chamber 220a and then to the dust collection channel 320. At this time, the middle sweeping roller brush 222 reverses and can suck the garbage in the accommodating chamber 1a into the dust collection bag of the base station 300.

[0057] in, Figures 1 to 3 The embodiment of the present application provides a dust box 100, which includes a box body 1 and an air guide plate 12. The box body 1 is provided with a receiving cavity 1a, a first air vent 1b, and a second air vent 1c. The first air vent 1b and the second air vent 1c are respectively connected to the receiving cavity 1a; the first air vent 1b is located between the two second air vents 1c; the second air vent 1c has an open state and a closed state;

[0058] The air guide plate 12 is provided in the accommodating chamber 1a. The air guide plate 12 is provided corresponding to the first vent 1b and divides the accommodating chamber 1a into two guide chambers. Each guide chamber is connected to a second vent 1c.

[0059] When the dust box 100 is in the dust collection state, the second vent 1c is in a closed state, and the air flows into the guide cavity from the first vent 1b;

[0060] When the dust box 100 is in the dust collecting state, the second vent 1c is in the open state; the air flow enters the guide cavity from the second vent 1c, and after being guided by the air guide plate, flows out from the first vent 1b.

[0061] It is understood that during the automatic dust collection process of the dust box 100, the negative pressure in the dust box 100 opens the two second vents 1c, and a large amount of air enters from both ends, generating airflows that cancel each other out in the middle, forming a swirling airflow. The garbage is trapped in the middle section by the swirling airflow and cannot be collected. To address this issue, in this embodiment, an air guide plate is added to the accommodating chamber 1a of the dust box 100. This not only prevents the airflows generated by both ends from canceling each other out in the middle section and creating a swirling airflow, but also effectively diverts and discharges garbage through the guidance of the air guide plate, thereby improving the dust collection efficiency of the cleaning robot 200.

[0062] In this embodiment, reference Figure 1 and Figure 3 One end of the air guide plate corresponds to the first vent 1b, and the other end corresponds to the air outlet 1d. In this embodiment, the two second vents 1c are respectively provided on two opposite side walls of the dust box, and the air guide plate of the dust box 100 is designed to be located between the air outlet 1d. This not only achieves the purpose of uniform waste diversion, but also ensures uniform airflow from the two opposite side walls of the dust box 1 to the air outlet 1d.

[0063] like Figure 3 As shown, in order to improve the guiding effect of air flow, in the technical solution of this embodiment, the air guide plate is respectively provided with a guide surface 12a facing each of the second air vents 1c; when the dust box is in the dust collecting state, the air flow entering the guide cavity from the second air vent 1c is guided to the first air vent 1b through the guide surface 12a.

[0064] like Figure 3 As shown, in this embodiment, the guide surface 12a is configured as an arcuate surface. In other embodiments, the guide surface 12a can also be configured as a plane. It is understood that configuring the guide surface 12a as an arcuate surface can provide a certain buffering effect on the airflow, making the airflow flow more stable.

[0065] like Figure 3As shown, in this embodiment, the cross-section of the air deflector 12 is triangular, with the junction of the two guide surfaces 12a facing the first vent 1b. The junction of the two guide surfaces 12a is defined as the windbreak. The side of the air deflector away from the cloak corresponds to the middle of the air outlet 1d. The upper and lower portions of the air deflector are connected to the box body.

[0066] Among them, when the dust box is in the dust suction state, the cloak can also divert the airflow entering from the first air vent. The diverted airflow enters the two guide cavities respectively and flows to the air outlet 1d through the guide surface.

[0067] like Figure 1 As shown, in the technical solution of this embodiment, the box body 1 includes a first box shell 13 and a second box shell 14, the first box shell 13 and the second box shell 14 are rotatably connected, and the first box shell 13 and the second box shell 14 are locked or released by a connecting button 15; the first air vent 1b is provided in the first box shell 13, and the second air vent 1c is provided in the second box shell 14; the air guide plate 12 is provided in the second box shell 14.

[0068] It can be understood that the dust box 100 can be opened with one click by setting the connection button 15, so as to achieve the purpose of manually cleaning the garbage. Moreover, the first box shell 13 and the second box shell 14 are set so that when the first box shell 13 and the second box shell 14 are rotated to open (such as Figure 1 As shown), it opens up a larger area, making it easier to clean up stubborn garbage.

[0069] like Figure 1 and Figure 3 As shown, in the technical solution of this embodiment, the two second vents 1c are respectively located on two opposite side walls of the second box shell.

[0070] It is understandable that if the second vent 1c is only provided on one side wall of the housing 1, negative pressure will generate airflow toward the center. Due to inertia or the large flow rate in the center, the garbage will flow to the other end, forming a dead zone in this area and poor dust collection. By providing the second vent 1c on both opposing side walls of the housing 1, airflow is generated at both ends, achieving clean dust collection.

[0071] like Figure 1 As shown, in the technical solution of this embodiment, the second vent 1c is arranged at the lower position of the side wall of the second box shell. In this way, there is no dead angle in the accommodating chamber 1a, and the dust collection is more dry and quiet.

[0072] like Figures 1 to 3As shown, the dust box 100 also includes a window shield 2, which is connected to the box body 1 and is used to close or open the second air vent 1c, which is a through hole; wherein, when the dust box is in a dust suction state, when the air flow enters the accommodating cavity 1a from the first air vent 1b, the window shield 2 closes the second air vent 1c; when the dust box is in a dust collecting state, when the air flow flows out of the accommodating cavity 1a from the first air vent 1b, the window shield 2 opens the second air vent.

[0073] In this way, when it is necessary to automatically clean the garbage in the dust box 100, the cleaning robot 200 docks with the base station 300. When the fan 230 of the base station 300 is started, a large negative pressure is formed in the accommodating chamber 1a, and the window shield 2 of the dust box 100 rotates to the open state under the action of the negative pressure (refer to FIG. Figure 2 ), the air flow direction is from the second vent 1c to the first vent 1b (refer to Figure 3 ), driving the garbage in the accommodating chamber 1a to be discharged from the first vent 1b, so that the garbage in the dust box 100 can be collected through the base station 300; the dust box 100 in the present application has a simple structure and low cost, and only the second vent 1c and the window shield 2 are opened on the box body 1, which can meet the requirements of the normal operation of the cleaning robot 200 and the automatic dust collection.

[0074] It should be noted that the negative pressure generated when the fan 230 of the cleaning robot 200 is working is smaller than the negative pressure generated when the dust collecting fan of the base station 300 is working. Therefore, when the fan 230 of the cleaning robot 200 is working, the negative pressure formed in the accommodating chamber 1a is not enough to drive the window shield 2 to move. Therefore, when the cleaning robot 200 is performing cleaning work, the window shield 2 always closes the second air vent 1c, and the direction of the airflow is from the first air vent 1b to the accommodating chamber 1a, so as to bring dust and other garbage from the first air vent 1b into the accommodating chamber 1a of the dust box 100.

[0075] like Figure 2 As shown, in the technical solution of this embodiment, the window covering member 2 includes a first connecting portion 21 and a shielding portion 22, and the first connecting portion 21 is connected to the box body 1 through a connecting member 24; the shielding portion 22 is rotatably connected to the first connecting portion 21 to close or open the second vent 1c.

[0076] It is understood that the connection between the window shield 2 and the housing 1 is achieved through the first connecting portion 21, and the second vent 1c is blocked or opened through the shielding portion 22. The shielding portion 22 rotates under the negative pressure generated by the dust collection fan of the base station 300 to open the second vent 1c.

[0077] like Figure 2As shown, in the technical solution of this embodiment, the first connecting portion 21 and the shielding portion 22 are an integral connection structure; and a groove 22a is provided on the side of the shielding portion 22 away from the wall of the accommodating cavity 1a at a position close to the first connecting portion 21.

[0078] It is understood that the first connecting portion 21 and the shielding portion 22 are integrally connected, achieving an effect of easy processing and forming. By locally digging a groove 22a in the shielding portion 22, the stress intensity at the groove 22a can be reduced, which can facilitate the movement of the shielding portion 22 under negative pressure. As shown in Figure 2, the shielding portion 22 deforms, bends and rotates at the groove 22a.

[0079] In the technical solution of this embodiment, the window shield 2 is made of elastic material.

[0080] It is understood that the window shield 2 made of elastic material can have a resilient property. During automatic dust collection, due to the presence of elasticity, when the negative pressure reaches a certain level, the window shield 2 can be driven to move, so that the window shield 2 is away from the wall of the box body 1, thereby achieving the purpose of opening the second vent 1c. And because the elastic material has a resilient property, when the negative pressure is less than a certain level or when the negative pressure disappears, the window shield 2 returns to the position of closing the second vent 1c under the action of elasticity (refer to Figure 2 closed state shown in ).

[0081] Optionally, in the technical solution of this embodiment, the window shield 2 is made of silicone or rubber. Silicone or rubber is not only elastic, but also low in cost and easy to process and shape.

[0082] In this embodiment, the connecting member 24 may be a rivet.

[0083] like Figure 1 As shown, in the technical solution of this embodiment, the inner wall surface of the box body 1 is provided with a vent boss 11. In this embodiment, the inner wall surface of the second box shell 14 is provided with a vent boss 11. The vent boss 11 includes a second connecting portion 111 and a protruding portion 112. The connection between the second connecting portion 111 and the protruding portion 112 is stepped to form a second step portion 113.

[0084] The first connecting portion 21 is connected to the second connecting portion 111; the second step portion 113 is adapted to the first step portion 23; the second vent 1c is provided corresponding to the vent boss 11 and passes through the raised portion 112; the shielding portion 22 is provided corresponding to the raised portion 112 and is used to abut against or move away from the raised portion 112 to close or open the second vent 1c;

[0085] It is understandable that by providing the first step portion 23 and the second step portion 113, the ventilation boss 11 can limit the window shade 2 and prevent the window shade 2 from rotating in other directions (for example, it can prevent rotation around the axis of the rivet).

[0086] In the technical solution of this embodiment, the side of the protrusion 112 facing the shielding portion 22 is defined as the shielding side, the shielding side is inclined toward the accommodating cavity 1a, and the upper part of the shielding side is located outside the accommodating cavity 1a when projected to the bottom of the box body 1.

[0087] It is understood that by setting the shielding side of the protrusion 112 to be inclined, the shielding portion 22 can be sealed against the protrusion 112. When the negative pressure disappears and the shielding portion 22 automatically rebounds to the shielding state, the shielding portion 22 will automatically and completely adhere to the shielding side of the protrusion 112 under the action of elasticity and gravity, thereby sealing the second vent 1c.

[0088] In one embodiment, the angle between the plane where the shielding side is located and the vertical direction is between 1-30 degrees. When the negative pressure in the accommodating chamber 1a is small, the resilience of the shielding member and gravity are used to seal the second vent 1c.

[0089] In the technical solution of this embodiment, the automatic dust collection principle of the cleaning equipment is as follows: the dust collection fan of the base station 300 generates a large negative pressure suction when working, and the negative pressure acts on the middle sweeping chamber 220a of the sweeping robot through the dust collection channel 320 of the base station 300 and enters the accommodating chamber 1a of the dust box 100, generating an instantaneous large negative pressure to open the window shielding parts 2 at both ends of the dust box 100, generating a large amount of airflow to suck the garbage from the accommodating chamber 1a into the middle sweeping chamber 220a, and the garbage is swept out by the reverse rotation of the middle sweeping roller brush 222 and then sucked into the dust collection bag of the base station 300.
