Among them, cleaning robots are mainly engaged in cleaning and washing work, such as automatically completing the cleaning work of the ground, windows, etc., including floor sweeping robots, mopping robots, sweeping and mopping integrated robots, window cleaning robots, and some robots for cleaning special scenarios. Cleaning robots can reduce manual cleaning work and bring convenience to life and work.

[0003] In related technologies, most cleaning robots are equipped with a dust box that can be detachably installed on the main body. During operation, under the action of the negative pressure suction of the main body, various domestic wastes such as debris and hair enter the inside of the dust box and are collected by the dust box. After the dust box is full, it is necessary to manually remove the dust box from the main body, then pour out the garbage inside the dust box and clean it up before reinstalling it into the main body. However, frequent installation and disassembly of the dust box easily cause damage to the connection part between the dust box and the main body, thereby increasing the maintenance frequency and maintenance cost; moreover, the structure of the installation part of the main body for the detachably connected dust box is relatively complex, resulting in an increase in cost.

[0025] To make the above objects, features, and advantages of the present application more obvious and understandable, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below

[0026] Refer to Figures 1 to 3 , Figure 1 which shows an exploded structure diagram of a cleaning robot according to an embodiment of the present application

[0027] Figure 2 And Figure 3 respectively show Figure 1Structural diagrams of two different perspectives of the main body 10 in the shown structure. A cleaning robot provided by an embodiment of the present application, the cleaning robot includes: a main body 10, a dust box 20, and a negative pressure device 30. A dust suction port 101 is formed at the bottom of the main body 10. Among them, the main body 10 can provide an installation basis for the installation of other structures. The dust box 20 is arranged inside the main body 10 and is integrated with the main body 10, and is used to store garbage such as dust, debris, hair, and sundries cleaned from the surface to be cleaned. Specifically, for example, a dust inlet 201 communicating with the dust suction port 101 is formed on the bottom wall of the dust box 20. The negative pressure device 30 is arranged inside the main body 10, and the negative pressure device 30 communicates with the dust box 20. Among them, the negative pressure device 30 includes but is not limited to a blower, which can generate negative pressure at the dust inlet 201 during operation, and garbage such as dust, debris, hair, and sundries enter the inside of the dust box 20 through the dust suction port 101 and the dust inlet 201 in sequence, and the dust box 20 can store the entered garbage.

[0028] For the above-mentioned cleaning robot, when the dust box 20 and the main body 10 are integrated, compared with the detachable setting method, it can achieve better sealing of other parts except the channel during dust collection, with better sealing performance, and can simplify the structure, reduce costs, and reduce the number of maintenance times. At the same time, since there is no need to remove the dust box 20, the operation is relatively more convenient. In addition, the dust box 20 and the main body 10 are designed as an integrated structure, which can realize mass production, improve production efficiency, make the assembly efficiency of the cleaning robot higher, and at the same time reduce the occupied space of the main body 10, making the product smaller.

[0029] In some embodiments, a discharge port 202 is formed at the top of the dust box 20. The cleaning robot further includes a plugging assembly 40. The plugging assembly 40 is openably arranged at the top of the dust box 20, and can plug the discharge port 202 when in the closed state. When the plugging assembly 40 is in the closed state, it can plug the discharge port 202, so that the discharge port 202 has good sealing performance, which can ensure the negative pressure suction capacity at the dust suction port 101 and is conducive to sucking garbage into the inside of the dust box 20. In this way, when the dust box 20 is full of garbage, the plugging assembly 40 is opened, and the garbage inside the dust box 20 is directly poured out through the discharge port 202, and for example, the inner wall of the dust box 20 is cleaned, without having to remove the dust box 20 from the main body 10 and then pour out the internal garbage.

[0030] Please refer to Figure 1, in some embodiments, a switch member 13 is provided on the main body 10 and is disposed at the dust inlet 201 in an openable and closable manner. The switch member 13 includes, but is not limited to, a plate member rotatably or telescopically disposed at the dust inlet 201. When the negative pressure device 30 is in suction operation, the switch member 13 is opened by the driving member or opened under the driving of the negative pressure, and the garbage at the dust suction port 101 can enter the dust box 20 through the dust inlet 201; when the negative pressure device 30 stops the suction operation, the switch member 13 closes correspondingly, no longer sucking in garbage, and at the same time can prevent the garbage inside the dust box 20 from leaking out through the dust inlet 201 and the dust suction port 101.

[0031] Please refer to Figure 3 , in some embodiments, the cleaning robot further includes a cleaning brush assembly 50. The cleaning brush assembly 50 is installed on the main body 10. Specifically, the cleaning brush assembly 50 includes one or more first cleaning brushes 51 rotatably disposed on the main body 10 and passing through the dust suction port 101. The first cleaning brush 51 is, for example, a roller brush, passing through the dust suction port 101 and at least partially exposed from the dust suction port 101, and can clean the surface to be cleaned when rotating relative to the main body 10, enabling the dust and debris on the surface to be cleaned to enter the interior of the dust box 20 through the dust suction port 101. In addition, the cleaning brush assembly 50 further includes one or more second cleaning brushes 52 rotatably disposed on the bottom surface of the main body 10. When the second cleaning brushes 52 rotate, they contact the surface to be cleaned and push the dust and debris on the surface to be cleaned to the vicinity of the dust suction port 101, so as to be sucked into the interior of the dust box 20 by the dust suction port 101. In addition, since the dust box 20 does not need to be removed from the main body 10, the sealing positions are relatively reduced, and the sealing reliability is improved.

[0032] In some embodiments, the dust box 20 and the main body 10 are integrally formed, which can be made of a metal part or a plastic part, and the material is selected according to actual needs. Among them, the dust box 20 and the main body include, but are not limited to, various integral forming methods such as injection molding integral forming, sheet metal integral forming, or die casting integral forming. The integral forming method has a relatively high production efficiency; or it can also be welded into an integral structure, etc.

[0033] In a specific embodiment, the main body 10 includes a top surface shell 11, and the top of the dust box 20 and the top surface shell 11 are provided as an integral structure. In this way, the dust box 20 cannot be removed separately; in addition, a discharge port 202 is formed on the top surface shell 11, which is convenient for pouring out the garbage inside the dust box 20 through the discharge port 202 and for cleaning the inner wall of the dust box 20.

[0034] In some embodiments, the main body 10 further includes a bottom shell 12 located below the top shell 11 and connected to the top shell 11. The dust suction port 101 is formed on the bottom shell 12. The bottom shell 12 and the top shell 11 are connected by various fasteners including but not limited to pins, rivets, screws, etc., or by snap connection or bonding. Various components such as the negative pressure device 30 are disposed inside the installation chamber formed by the enclosure of the bottom shell 12 and the top shell 11. In this way, the main body 10 not only prevents various components from being exposed, making the appearance beautiful, but also plays a good protective role.

[0035] Please refer to Figure 1 、 Figure 4 and Figure 5 , in one embodiment, the blocking assembly 40 is formed with a communication channel and includes a filter element 41 disposed inside the communication channel. The air inlet end 4221 of the communication channel is in communication with the dust box 20, and the air outlet end 4211 of the communication channel is in communication with the negative pressure device 30. In this way, under the suction force of the negative pressure device 30, the gas entering the inside of the dust box 20 flows through the communication channel of the blocking assembly 40 to the negative pressure device 30. During the process of the gas entering the communication channel, the filter element 41 filters the gas, thereby preventing defects such as dust or debris and other garbage from entering the negative pressure device 30 through the communication channel and causing the blockage of the negative pressure device 30 and making the negative pressure device 30 unable to work; compared with the method of disposing the filter element 41 inside the main body 10 and in front of the suction part 31 of the negative pressure device 30, the filter element 41 in this embodiment is located inside the blocking assembly 40 and can be disassembled and cleaned together with the blocking assembly 40. The cleaning operation is relatively easier and the cleaning efficiency is higher.

[0036] In some embodiments, the filter element 41 includes but is not limited to one or more of filter cotton, filter membrane, filter paper, filter net, etc., and can be specifically selected and set flexibly according to actual needs.

[0037] Please refer to Figure 1 、 Figure 4 and Figure 5, in some embodiments, an air outlet 203 corresponding to the suction part 31 of the negative pressure device 30 is formed on the side wall of the dust box 20. For example, the suction part 31 extends into the dust box 20 through the air outlet 203 and is butt-connected and communicated with the air outlet end 4211 of the communication channel. In addition, the suction part 31 is inserted into the air outlet 203 and is in interference fit with the air outlet 203 to improve the sealing performance at the docking position, or a sealing ring is arranged on the outer side of the suction part 31 and the wall of the air outlet 203 to improve the sealing performance at the docking position. In addition, the air outlet end 4211 of the communication channel is formed on the side wall of the plugging component 40, and the suction part 31 and the air outlet end 4211 of the communication channel are in abutment with the side wall of the plugging component 40, so that the air outlet end 4211 of the communication channel is butt-connected and communicated with the suction part 31 of the negative pressure device 30.

[0038] In one embodiment, the filter element 41 is arranged at the air inlet end 4221, and the air inlet end 4221 is located at the bottom of the plugging component 40. In this way, during the suction process of the negative pressure device 30, the dust, debris and other garbage filtered by the filter element 41 will directly fall into the dust box 20 under the action of gravity, which can prevent the garbage from entering the communication channel and causing blockage failure, and is also convenient for cleaning.

[0039] Please refer to Figure 1 , Figure 4 and Figure 5 , in one embodiment, the plugging component 40 further includes a plugging box 42. The air inlet end 4221 of the communication channel is formed on the bottom wall of the plugging box 42, and the air outlet end 4211 of the communication channel is formed on the side wall of the plugging box 42. In this way, the entire area of the plugging box 42 between the air inlet end 4221 and the air outlet end 4211 corresponds to the communication channel. The gas filtered by the filter element 41 enters the interior of the plugging box 42 and is then sucked into the negative pressure device 30 through the air outlet end 4211. The internal space volume of the plugging box 42 is relatively large and is not easily blocked. In addition, the outer contour of the plugging box 42 is adapted to the contour of the discharge port 202, and has good sealing performance for the discharge port 202 when in the closed state.

[0040] In one embodiment, the plugging component 40 further includes a mounting member 43 detachably mounted at the air inlet end 4221. The filter element 41 is mounted on the mounting member 43. Specifically, the mounting member 43 includes, but is not limited to, a mounting seat having a hollow opening 431. Under the suction force of the negative pressure device 30, the gas inside the dust box 20 can enter the interior of the plugging box 42 through the hollow opening 431 and the filter element 41. In addition, the mounting member 43 is mounted at the air inlet end 4221 by, but is not limited to, a snap-fit method, which facilitates the disassembly and maintenance of the mounting member 43 and the filter element 41 from the plugging box 42 and the regular replacement of the filter element 41.

[0041] In some embodiments, a handle 432 is further provided on the mounting member 43. Manually acting on the handle 432 facilitates the disassembly and assembly of the mounting member 43.

[0042] In some embodiments, the plugging box 42 includes a plugging shell 421 with an opening at the bottom and a plugging plate 422 connected to the bottom of the plugging shell 421. The plugging plate 422 seals the opening. The air inlet end 4221 is specifically arranged on the plugging plate 422. In this way, the plugging box 42 is processed and produced by separating the plugging shell 421 and the plugging plate 422. Compared with the way of integrally processing the plugging box 42, the processing difficulty is lower, which is convenient for mass production. Specifically, the plugging box 42 and the plugging plate 422 are independently selected according to actual needs, and both are specifically, for example, integrally formed by injection molding, which can ensure the sealing performance of the plugging box 42.

[0043] In one embodiment, the cleaning robot further includes a sensing member 44 arranged on the mounting member 43 and a detector arranged on the main body portion 10. The detector can detect the sensing member 44 and control the negative pressure device 30 to work according to whether the sensing member 44 is detected. Among them, the sensing member 44 includes, but is not limited to, a magnet. The detector judges whether there is a missing installation defect of the mounting member 43 and the filter member 41 according to the magnitude of the magnetic field intensity of the sensing member 44. Specifically, when there is a missing installation defect of the mounting member 43 and the filter member 41, the detector cannot correspondingly sense the sensing member 44, and correspondingly controls the negative pressure device 30 to stop working, so as to prevent the blockage failure caused by bringing garbage into the interior of the negative pressure device 30 and the main body portion 10 when the filter member 41 is not installed. In this way, the safety can be improved, the maintenance times can be reduced, and the machine life can be extended.

[0044] In some embodiments, the plugging assembly 40 further includes a decorative plate 45 detachably connected to the top of the plugging box 42. Specifically, a first clamping portion 4212 is provided on the top of the plugging box 42, and a second clamping portion corresponding to the first clamping portion 4212 is provided on the decorative plate 45. The decorative plate 45 is connected and clamped to the top of the plugging box 42 through the first clamping portion 4212 and the second clamping portion.

[0045] In some embodiments, the plugging assembly 40, specifically, for example, the plugging box 42, is installed inside the dust box 20 by a clamping method. In this way, it is convenient to remove the plugging assembly 40 from the dust box 20. Of course, the plugging assembly 40 can also be detachably installed inside the dust box 20 by other methods to realize the switching between the open state and the closed state.

[0046] In one embodiment, the cleaning robot further includes a seal 60 disposed circumferentially around the plugging assembly 40, and the plugging assembly 40 abuts against the inner wall of the dust box 20 through the seal 60. Specifically, the seal 60 includes, but is not limited to, a sealing ring or a gasket. In this way, under the sealing action of the seal 60, the sealing performance of the plugging assembly 40 at the closed state for the discharge port 202 can be improved, so that the dust box 20 forms a sealed chamber, and thus when the negative pressure device 30 works, the negative pressure suction capacity at the dust suction port 101 can be ensured, which is beneficial to sucking the garbage into the interior of the dust box 20.

[0047] In one embodiment, a step 204 is provided around the inner wall of the dust box 20, and the bottom edge of the plugging assembly 40 and the seal 60 both abut against the step 204. In this way, the step 204 plays a supporting role for the plugging assembly 40, which can improve the sealing performance and the stability of the plugging assembly 40 at the closed state.
