Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a dust box, cleaning equipment and cleaning system. Background Technology

[0002] Currently, cleaning equipment is typically equipped with a dust box. When the dust box accumulates to a certain amount, the base station fan inside the cleaning station will suck the dust from the dust box into the cleaning station. However, in order to improve the dust removal efficiency, the equipment fan inside the cleaning equipment needs to be turned on during the dust removal process, which results in increased noise and affects the user experience. Utility Model Content

[0003] In view of this, embodiments of this application provide a dust box, cleaning equipment, and cleaning system to solve the problem of increased noise during dust removal.

[0004] The first aspect of this application provides a dust box, including a box body, a first opening and closing member and a second opening and closing member, wherein the box body has an inner cavity and a negative pressure port, a dust suction port and a dust discharge port communicating with the inner cavity; the first opening and closing member is connected to the box body and is capable of opening and closing the dust discharge port, and the second opening and closing member is connected to the box body and is capable of opening and closing the negative pressure port; The dust box has a suction mode and a dust discharge mode. In the suction mode, the first opening and closing component is in the closed state to close the dust discharge port, and the second opening and closing component is in the open state to open the negative pressure port.

The equipment fan draws negative pressure into the dust box through the negative pressure port.

In the dust removal mode, the first opening and closing component is in the open state to open the dust outlet, and the second opening and closing component is in the closed state to close the negative pressure port. The base station fan draws negative pressure into the dust box through the dust outlet. Since the second opening and closing component can prevent outside air from entering the inner cavity of the dust box through the negative pressure port, it helps to increase the negative pressure in the inner cavity, thereby improving the dust removal effect. That is, there is no need to turn on the equipment fan inside the cleaning equipment during the dust removal process, solving the problem of increased noise during dust removal and improving the user experience.

[0006] In some embodiments, the dust box further has an air guide channel, and the negative pressure port is formed by the port of the air guide channel; the second opening and closing member is connected to the box body and is located at the negative pressure port.

[0014] In some embodiments, the filter element is arranged close to the cover plate, and the negative pressure port is located on one side of the filter element in the length direction of the housing.

[0015] In some embodiments, the dust box further includes a third opening and closing member, and the box body also has an air inlet communicating with the inner cavity. The third opening and closing member is connected to the box body and is capable of opening and closing the air inlet. Along the length of the box, the dust exhaust port and the air inlet are located at both ends of the box, and the suction port is located between the dust exhaust port and the air inlet.

[0016] In some embodiments, the dust box further has an air guide channel, and the negative pressure port is formed by the port of the air guide channel; the second opening and closing member is disposed inside the air guide channel.

[0017] The second aspect of this application provides a cleaning device that includes a dust box as described in the first aspect.

[0018] The cleaning device employs any one or more embodiments of the dust box described above, and thus has the beneficial effects of the embodiments described above, which will not be elaborated further here.

[0019] A third aspect of this application discloses a cleaning device, including a device fan, an exhaust duct, a dust box, and a second opening / closing component. The device fan is connected to the exhaust duct, and the dust box includes a box body and a first opening / closing component. The box body has a negative pressure port, a suction port, and a discharge port. The negative pressure port communicates with the exhaust duct. The first opening / closing component is connected to the box body and is capable of opening and closing the discharge port. The second opening / closing component is connected to the exhaust duct and is capable of opening and closing the exhaust duct. The dust box has a suction mode and a dust discharge mode. In the suction mode, the first opening and closing component is in the closed state to close the dust discharge port, and the second opening and closing component is in the open state to open the exhaust channel. In the dust discharge mode, the first opening and closing component is in the open state to open the dust discharge port, and the second opening and closing component is in the closed state to close the exhaust channel.

[0020] The beneficial effects of the cleaning equipment provided in this application embodiment are as follows: In the vacuuming mode, the first opening and closing component is in the closed state to close the dust outlet, and the second opening and closing component is in the open state to open the exhaust channel. The equipment fan draws negative pressure into the dust box through the exhaust channel and negative pressure port. At this time, the second opening and closing component has almost no impact on the negative pressure of the dust box. Under the action of negative pressure, ground debris enters the dust box through the vacuum outlet. In the dust removal mode, the first opening and closing component is in the open state to open the dust outlet, and the second opening and closing component is in the closed state to close the exhaust channel. The base station fan draws negative pressure into the dust box through the dust outlet. Since the second opening and closing component can prevent outside air from entering the inner cavity of the dust box through the exhaust channel and negative pressure port, it helps to increase the negative pressure in the dust box, thereby improving the dust removal effect. That is, there is no need to turn on the equipment fan in the cleaning equipment during the dust removal process, solving the problem of increased noise during dust removal and improving the user experience.

[0036] For related technologies, please refer to Figure 8 and Figure 9 The dust box 40 is generally designed with a suction port 41, a negative pressure port 42, and a dust discharge port 43. In the suction mode, the first opening and closing part 45 closes the dust discharge port 43, and the equipment fan draws negative pressure into the dust box 40 through the negative pressure port 42. Under the action of negative pressure, the ground garbage enters the dust box 40 through the suction port 41.

[0037] In dust removal mode, the first opening / closing component 45 opens the dust removal port 43. The base station fan draws negative pressure into the dust box 40 through the dust removal port 43. Airflow enters the dust box 40 through the suction port 41 and the negative pressure port 42, thereby sucking the debris inside the dust box 40 into the clean base station. However, because the dust box 40 has a cuboid structure, a dead zone with no airflow is created in the lower left corner of the dust box 40, resulting in debris residue in this area.

[0038] To address this, an air inlet 44 and a third opening / closing element 46 are designed in the lower left corner of the dustbin 40. The air inlet 44 is used to generate airflow into the dustbin 40, thereby carrying away the debris inside. However, to prevent airflow from entering the dustbin 40 during suction mode, the third opening / closing element 46 is designed with a torsion spring, requiring sufficient negative pressure inside the dustbin 40 to open (i.e., the negative pressure generated by the device fan on the dustbin 40 is insufficient to open the third opening / closing element 46). During dust extraction mode, the air resistance of the suction port 41 and negative pressure port 42 of the dustbin 40 is low, allowing airflow to more easily enter the dustbin 40 from these ports. The negative pressure generated by the base station fan on the inside of the dustbin 40 is insufficient to open the third opening / closing element 46. Therefore, in the latter part of the dust extraction process, the device fan needs to be turned on to exhaust air from the negative pressure port 42, thereby generating sufficient negative pressure inside the dustbin 40 to open the third opening / closing element 46. Since the device fan generates additional noise, the dust extraction noise increases, affecting the user experience.

[0039] To address the issue of increased noise during dust removal, this application proposes a dust box, cleaning equipment, and cleaning system.

[0040] An embodiment of the first aspect of this application provides a dust box. Please refer to... Figure 1 and Figure 2 The dustbin 10 includes a box body 11, a first opening and closing member 13, and a second opening and closing member 15. The box body 11 has an inner cavity 113 and a negative pressure port 1141, a suction port 115, and a dust discharge port 116 communicating with the inner cavity 113; the first opening and closing member 13 is connected to the box body 11 and can open and close the dust discharge port 116, and the second opening and closing member 15 is connected to the box body 11 and can open and close the negative pressure port 1141. The dust box 10 has a suction mode and a dust discharge mode. In the suction mode, the first opening and closing member 13 is in the off state to close the dust discharge port 116, and the second opening and closing member 15 is in the on state to open the negative pressure port 1141. In the dust discharge mode, the first opening and closing member 13 is in the on state to open the dust discharge port 116, and the second opening and closing member 15 is in the off state to close the negative pressure port 1141.

[0041] The inner cavity 113 is used to store waste during the cleaning process of the cleaning equipment. The box body 11 can be a cuboid structure, and correspondingly, the overall shape of the inner cavity 113 is rectangular.

[0042] When the dust box 10 is installed on the cleaning equipment, the negative pressure port 1141 connects the inner cavity 113 and the exhaust duct. The exhaust duct is connected to the equipment fan. The equipment fan draws negative pressure into the dust box 10 through the exhaust duct and the negative pressure port 1141, so that the inner cavity 113 is under negative pressure. Under the action of negative pressure, the garbage cleaned by the cleaning equipment enters the inner cavity 113 through the suction port 115.

[0043] When dust removal is required, the cleaning equipment stops at the cleaning base station, and the dust discharge port 116 is connected to the base station fan. The base station fan draws negative pressure on the dust box 10 through the dust discharge port 116, so that the inner cavity 113 is under negative pressure. Under the action of negative pressure, the garbage in the inner cavity 113 enters the cleaning base station through the dust discharge port 116.

[0044] The beneficial effects of the dust box 10 provided in this application embodiment are as follows: When in the dust suction mode, the first opening and closing member 13 is in the closed state to close the dust discharge port 116, and the second opening and closing member 15 is in the open state to open the negative pressure port 1141. The equipment fan draws negative pressure on the dust box 10 through the negative pressure port 1141. At this time, the second opening and closing member 15 has almost no impact on the negative pressure of the dust box 10. Under the action of negative pressure, ground garbage enters the inner cavity 113 of the dust box 10 through the dust suction port 115. When in the dust discharge mode, the first opening and closing member 13 is in the open state to open the dust discharge port 116, and the second opening and closing member 15 is in the closed state to close the negative pressure port 1141. The base station fan draws negative pressure on the dust box 10 through the dust discharge port 116. Since the second opening and closing member 15 can prevent outside air from entering the inner cavity 113 of the dust box 10 through the negative pressure port 1141, it is beneficial to increase the negative pressure of the inner cavity 113, thereby improving the dust discharge effect. That is, there is no need to turn on the equipment fan inside the cleaning device during the dust removal process, which solves the problem of increased noise during dust removal and improves the user experience.

[0045] Please refer to Figure 5 In some embodiments, the first opening and closing member 13 is a flexible member, for example, the flexible member can be a rubber member. The first opening and closing member 13 includes a fixed part and a movable part connected to the fixed part. The fixed part is fixed to the box body 11 by threaded fasteners 131 (e.g. screws, bolts). The movable part can rotate relative to the fixed part. During cleaning, under the negative pressure of the equipment fan, the movable part closes the dust discharge port 116. During dust discharge, under the negative pressure of the base station fan, the movable part opens the dust discharge port 116.

[0046] Please refer to Figure 1 , Figure 2 and Figure 6 In some embodiments, the dust box 10 also has an air guide channel 114, and a negative pressure port 1141 is formed by the port of the air guide channel 114; the second opening and closing member 15 is connected to the box body 11 and is located at the negative pressure port 1141.

[0047] The shape of the air guide channel 114 is not limited in this application. For example, the air guide channel 114 can be an arc-shaped channel or a straight channel.

[0048] Understandably, the air guide channel 114 can be a single, integrated channel; this design facilitates the fabrication of the air guide channel 114. Alternatively, please refer to... Figure 6The air guide channel 114 may also include at least two sub-channels, for example, two sub-channels. With this design, the cross-sectional size of each sub-channel is smaller, which is beneficial to improving suction power.

[0049] The air duct 114 includes an inner port inside the housing 11 and an outer port outside the housing 11. During vacuuming, airflow enters through the inner port and exits through the outer port. Understandably, the negative pressure port 1141 can be formed by either the outer port or the inner port of the air duct 114.

[0050] Based on the above technical solution, compared to placing the second opening and closing component 15 inside the air guide channel 114, placing the second opening and closing component 15 at the port of the air guide channel 114 is more conducive to the installation and disassembly of the second opening and closing component 15.

[0051] In some other embodiments, when the housing 11 has an air guide channel 114, the second opening / closing member 15 can also be disposed inside the air guide channel 114, that is, the second opening / closing member 15 is located between the outer port and the inner port of the air guide channel 114. Of course, the housing 11 may not have an air guide channel 114, but only a negative pressure port 1141, for example, the negative pressure port 1141 is disposed on the cover plate 112 of the housing 11.

[0052] Please refer to Figure 1 and Figure 3 In some embodiments, the dust box 10 further includes a sealing frame 17 connected to the box body 11 and disposed at the negative pressure port 1141. The second opening and closing member 15 is integrally formed with the sealing frame 17, and the sealing frame 17 can improve the sealing performance of the second opening and closing member 15 when the negative pressure port 1141 is closed. The sealing frame 17 can be fixed at the negative pressure port 1141 by adhesive bonding.

[0053] In some embodiments, the second opening / closing member 15 and the sealing frame 17 are rubber components, that is, the sealing frame 17 is a rubber frame, and the second opening / closing member 15 is a rubber opening / closing member. The second opening / closing member 15 can be flipped using the elasticity of the rubber itself. That is, in the dust suction mode, under the suction force of the device fan, the suction force is greater than the elastic force of the second opening / closing member 15, and the second opening / closing member 15 opens the negative pressure port 1141. In the dust exhaust mode, under the suction force of the base station fan, the second opening / closing member 15 closes the negative pressure port 1141, preventing airflow.

[0054] In some embodiments, the second opening / closing member 15 is a plate-like structure.

[0055] Please refer to Figure 4 In some embodiments, the second opening / closing member 15 is rotatably connected to the housing 11.

[0056] In some embodiments, the dust box 10 further includes a sealing ring 16 connected to the box body 11 and disposed at the negative pressure port 1141. The second opening and closing member 15 is pressed against the sealing ring 16 when the negative pressure port 1141 is closed, thereby improving the sealing performance.

[0057] In some embodiments, the second opening / closing element 15 is a Mylar sheet, which is a thin sheet made of polyester material (such as polyethylene terephthalate, polyimide), which is lightweight and can be easily blown up by airflow.

[0058] In some embodiments, the sealing ring 16 is sealing foam.

[0059] When in vacuuming mode, the second opening and closing part 15 is blown up by the airflow under the suction of the equipment fan to open the negative pressure port 1141 without obstructing the airflow; when in dust removal mode, the second opening and closing part 15 is pressed against the sealing ring 16 under the suction of the base station fan to close the negative pressure port 1141, preventing the airflow from entering the inner cavity 113 of the box 11 from the air guide channel 114, thereby increasing the negative pressure in the inner cavity 113.

[0060] In some other embodiments, when the second opening and closing member 15 is rotatably connected to the box body 11, the second opening and closing member 15 can also be driven to rotate by a driving device (e.g., a motor). When in the dust suction mode, the driving device drives the second opening and closing member 15 to open the negative pressure port 1141. When in the dust exhaust mode, the driving device drives the second opening and closing member 15 to close the negative pressure port 1141.

[0061] Please refer to Figure 1 and Figure 2 In some embodiments, the box body 11 includes a box body 111 and a cover plate 112 connected to the box body 111, the box body 111 and the cover plate 112 forming an inner cavity 113; the dust box 10 also includes a filter element 12, the filter element 12 is disposed in the inner cavity 113 and divides the inner cavity 113 into a first chamber 1131 and a second chamber 1132, the negative pressure port 1141 is connected to the first chamber 1131, and the dust suction port 115 and the dust discharge port 116 are connected to the second chamber 1132.

[0062] The second chamber 1132 is larger than the first chamber 1131.

[0063] Understandably, in the vacuuming mode, the waste enters from the vacuum port 115 and is stored in the second chamber 1132; in the dust removal mode, the waste stored in the second chamber 1132 enters the cleaning base station through the dust removal port 116.

[0064] Understandably, the cover plate 112 is detachably connected to the box body 111 to facilitate the installation and removal of the cover plate 112, thereby facilitating the replacement of the filter element 12. Specifically, the cover plate 112 can be detachably connected to the box body 111 via a snap-fit ​​mechanism.

[0065] In some embodiments, the filter element 12 is inclinedly disposed within the inner cavity 113, and the end of the filter element 12 near the negative pressure port 1141 is lower than the end of the filter element 12 away from the negative pressure port 1141; thus, during vacuuming, it facilitates the creation of negative pressure within the inner cavity 113 of the housing 11. The filter element 12 includes a mounting bracket and a filter screen mounted on the mounting bracket, and the filter element 12 is mounted within the inner cavity 113 via the mounting bracket.

[0066] Please refer to Figure 2 In some embodiments, the filter element 12 is arranged close to the cover plate 112, and the negative pressure port 1141 is located on one side of the filter element 12 in the length direction of the box body 11. It can be understood that the air guide channel 114 is located on one side of the filter element 12 in the length direction of the box body 11.

[0067] Wherein, the length direction of box 11 is Figure 2 The X direction in the equation.

[0068] Understandably, the angle between the filter element 12 and the cover plate 112 is an acute angle, for example, the angle can be 10°, 15°, 20°, 25° or 30°, etc.; or, the filter element 12 and the cover plate 112 are arranged in parallel.

[0069] By arranging the filter element 12 close to the cover plate 112, the second chamber 1132 is made larger, which can store more waste during cleaning, thereby reducing the number of dust discharges and improving cleaning efficiency.

[0070] Please refer to Figure 1 and Figure 2 In some embodiments, the dust box 10 further includes a third opening and closing member 14, and the box body 11 also has an air inlet 117 communicating with the inner cavity 113. The third opening and closing member 14 is connected to the box body 11 and can open and close the air inlet 117. In the length direction of the box body 11, the dust discharge port 116 and the air inlet 117 are located at both ends of the box body 11, and the dust suction port 115 is located between the dust discharge port 116 and the air inlet 117.

[0071] In some embodiments, the third opening and closing member 14 is rotatably connected to the box body 11 via a rotating shaft, and a torsion spring 141 is sleeved on the rotating shaft. During vacuuming, the third opening and closing member 14 closes the air inlet 117 under the elastic force of the torsion spring 141. During dust discharge, the negative pressure overcomes the elastic force of the torsion spring 141, causing the third opening and closing member 14 to open the air inlet 117, that is, the airflow enters the inner cavity 113 through the air inlet 117 to carry away the garbage at the end of the box body 11, thereby improving the cleaning effect.

[0072] It should be noted that during dust removal, since the second opening and closing part 15 can prevent outside air from entering the inner cavity 113 of the dust box 10 through the negative pressure port 1141, it is beneficial to increase the negative pressure of the inner cavity 113, thereby ensuring that the third opening and closing part 14 can overcome the elastic force of the torsion spring 141 to open the air inlet 117 under negative pressure, so that the garbage at the air inlet 117 can be sucked into the dust collection container of the cleaning base station.

[0073] A second aspect of this application discloses a cleaning device. This cleaning device includes a dustbin 10 as described in the first aspect. The cleaning device can be a robotic vacuum cleaner.

[0074] The cleaning device employs any one or more embodiments of the dust box 10 described above, and thus has the beneficial effects of the above embodiments, which will not be elaborated further here.

[0075] The third aspect of this application proposes a cleaning device. Please refer to... Figures 7 to 10 The cleaning equipment includes a fan 20, an exhaust duct 30, a dust box 40, and a second opening / closing component 50. The fan 20 is connected to the exhaust duct 30. The dust box 40 includes a box body 47 and a first opening / closing component 45. The box body 47 has a negative pressure port 42, a suction port 41, and a dust discharge port 43. The negative pressure port 42 is connected to the exhaust duct 30. The first opening / closing component 45 is connected to the box body 47 and can open and close the dust discharge port 43. The second opening / closing component 50 is located in the exhaust duct 30 and can open and close the exhaust duct 30.

[0076] The dust box 40 has a suction mode and a dust discharge mode. In the suction mode, the first opening and closing part 45 is in the off state to close the dust discharge port 43, and the second opening and closing part 50 is in the open state to open the exhaust duct 30. In the dust discharge mode, the first opening and closing part 45 is in the open state to open the dust discharge port 43, and the second opening and closing part 50 is in the off state to close the exhaust duct 30.

[0077] In some embodiments, please refer to Figure 7 The equipment fan 20 is connected to one end of the exhaust duct 30, and the other end of the exhaust duct 30 is connected to the dust box 40 and connected to the negative pressure port 42. Of course, the equipment fan 20 can also be connected to the middle of the exhaust duct 30, that is, a part of the exhaust duct 30 is connected to the inlet of the equipment fan 20, and the other part of the exhaust duct 30 is connected to the outlet of the equipment fan 20.

[0078] In some embodiments, please refer to Figure 10 The second opening / closing component 50 is connected to the port of the exhaust duct 30, for example, the second opening / closing component 50 is connected to the port of the exhaust duct 30 near the dust box 40. Of course, the second opening / closing component 50 can also be located inside the exhaust duct 30.

[0079] In some embodiments, the dust box 40 further includes a third opening and closing member 46, and the box body 47 also has an air inlet 44. The third opening and closing member 46 is connected to the box body 47 and is capable of opening and closing the air inlet 44.

[0080] It should be noted that the second opening and closing member 50 can adopt the structure of the second opening and closing member 15 in the first aspect, the first opening and closing member 45 can adopt the structure of the first opening and closing member 13 in the first aspect, and the third opening and closing member 46 can adopt the structure of the third opening and closing member 14 in the first aspect, which will not be described in detail here.

[0081] The beneficial effects of the cleaning equipment provided in this application embodiment are as follows: When in the dust suction mode, the first opening and closing part 45 is in the closed state to close the dust discharge port 43, and the second opening and closing part 50 is in the open state to open the exhaust channel 30. The equipment fan 20 draws negative pressure into the dust box 40 through the exhaust channel 30 and the negative pressure port 42. At this time, the second opening and closing part 50 hardly affects the negative pressure of the dust box 40. Under the action of negative pressure, the ground garbage enters the dust box 40 through the dust suction port 41. When in the dust discharge mode, the first opening and closing part 45 is in the open state to open the dust discharge port 43, and the second opening and closing part 50 is in the closed state to close the exhaust channel 30. The base station fan draws negative pressure into the dust box 40 through the dust discharge port 43. Since the second opening and closing part 50 can prevent outside air from entering the inner cavity of the dust box 40 through the exhaust channel 30 and the negative pressure port 42, it is beneficial to increase the negative pressure in the dust box 40, thereby improving the dust discharge effect. That is, there is no need to turn on the equipment fan 20 inside the cleaning equipment during the dust removal process, which solves the problem of increased noise during dust removal and improves the user experience.

[0082] The fourth aspect of this application proposes a cleaning system comprising a cleaning base station and cleaning equipment as described in the second or third aspect, wherein the cleaning base station is used to park the cleaning equipment.

[0083] The cleaning system employs any one or more embodiments of the cleaning equipment described above, and thus has the beneficial effects of the embodiments described above, which will not be elaborated further here.
