Referring to fig. 1-3, the housing assembly 10 includes: a main housing 11 and a first module 15. The main housing 11 includes a base 12 and a side portion 13, the base 12 including opposing first and second sides 121, 122, the side portion 13 being disposed around the base 12 to form a cavity 14 at the first side 121 of the base 12.

Referring to fig. 1 and 3, the first module 15 is located on the second side 122 of the base 12.

Referring to fig. 1 and 4, the first module 15 includes a first cleaning rack 16, the first cleaning rack 16 is connected to the bottom 12, and at least a part of an orthographic projection of the first cleaning rack 16 on a plane P (shown in fig. 4) is located outside an orthographic projection of the main housing 11 on the plane P, which may be a bottom surface of the bottom 12 on the second side 122 or a plane in which the bottom surface of the bottom 12 on the second side 122 is located.

For example, referring to fig. 1 and 4, the cleaning device 1 may further include a second module 17 located on the second side 122 of the base 12 and spaced apart from the first module 15. For example, the first module 15 and the second module 17 are arranged side by side. The second module 17 includes a second cleaning rack 18, and the first cleaning rack 16 and the second cleaning rack 18 are connected to the base 12, respectively. For example, the second cleaning frame 18 and the bottom 12 may be fixed on the bottom 12 by a fixing member such as a bolt after the insertion fitting, but the embodiment of the invention is not limited thereto.

For example, referring to fig. 1, 4-5, at least part of the orthographic projection of the second cleaning frame 18 on the plane P is also located outside the orthographic projection of the main housing 11 on the plane P.

For example, referring to fig. 6-8, the housing assembly 10 further includes an impact detection assembly 24 disposed at an end of the main housing 11 away from the first module 15 and configured to perform impact detection on the housing assembly 10, and a portion of the second cleaning rack 18 beyond the main housing 11 serves as a support plate 25 of the impact detection assembly 24.

The housing assembly 10 facilitates optimizing the dimensional fit of various components in the housing assembly, increases the effective cleaning area to improve cleaning efficiency, and realizes "collision detection" and "edge collision detection"; meanwhile, the risk of scratching between the main shell 11 and the external boundary can be effectively reduced, so that the probability of surface defects such as scratches is reduced, and the attractiveness of the cleaning device 1 is improved.

For example, the outer boundary includes a frame of a window, or a wall surface around the ground to be cleaned, but is not limited thereto.

For example, referring to fig. 1 to 3, the first direction Y may be a length direction of the housing assembly 10, the second direction X may be a width direction of the housing assembly 10, and the third direction Z may be a height direction of the housing assembly 10. The plane P is perpendicular to the height direction of the housing assembly 10. The first direction Y is parallel to the plane P. The second direction X is parallel to the plane P.

For example, the third direction Z is perpendicular to the first direction Y and perpendicular to the second direction X. For example, the first direction Y is perpendicular to the second direction X, but of course, there may be no strict perpendicular relationship between the first direction Y and the second direction X. For example, the angle between the first direction Y and the second direction X may be 85 ° to 95 °, but is not limited thereto, and the embodiment of the present invention is described with the angle between the first direction Y and the second direction X being 90 °. For example, the housing assembly 10 may serve as a lower housing assembly of the cleaning device 1.

For example, referring to fig. 1-3, the cavity 14 is a cavity defined by the bottom 12 and the side 13 of the main housing 11. At the first side 121 of the base 12 and in the cavity 14, the housing assembly may be provided with various components, for example, a control module or the like. On the second side 122 of the base 12, the first module 15 can be used as a cleaning module, connected to the base 12, and driven by the control module to perform a cleaning operation. For example, the first module 15 is a module with a rotation function, and the first module 15 can be detachably connected to the bottom 12 on the rotation center line thereof, so as to satisfy the requirement of the detachment and maintenance of the first module 15, but not limited thereto, the embodiment of the present invention does not limit the installation manner of the first module 15. For example, cleaning device 1 can be provided with a plurality of clean modules, and a plurality of clean modules can cooperate in order to realize good clean effect, the utility model discloses an embodiment does not do the restriction to the quantity and the form of clean module.

For example, referring to fig. 1 and 4, the plane P may be the plane of the bottom surface of the base 12 at the second side 122 and the plane may be the plane of the base 12 furthest from the side 13. For example, in the case where the housing assembly 10 includes the first module 15 and the second module 17, the plane P may serve as a mating surface for the base 12 and the second cleaning rack 18 when they are mounted. For example, in the case where the housing assembly 10 includes only the first module 15, the plane P is a plane of the bottom surface of the bottom 12 at the second side 122, and the bottom surface of the bottom 12 at the second side 122 is a surface of the bottom 12 near the first cleaning rack 16. For example, when the cleaning apparatus 1 is placed on a horizontal plane, the plane P is parallel to the horizontal plane, but is not limited thereto. For example, the orthographic projection of the first cleaning rack 16 on the plane P is approximately circular, and the orthographic projection of the second cleaning rack 18 on the plane P is approximately square. For example, the first module 15 may be referred to as a puck module and the second module 17 may be referred to as a cube tray module.

For example, referring to fig. 1 and 4, at least a portion of the first cleaning frame 16 is protruded with respect to the main casing 11, i.e., such that at least a portion of the outermost boundary line of the first cleaning frame 16 is located outside the outermost boundary line of the main casing 11. Therefore, in the third direction Z, at least a part of the orthographic projection of the first cleaning frame 16 on the plane P is located outside the orthographic projection of the main housing 11 on the plane P. Therefore, when the size of the first cleaning frame 16 is increased, the size of the main housing 11 is not increased, thereby making it possible to make the design of the cleaning apparatus 1 more flexible and to improve the cleaning efficiency of the cleaning apparatus 1.

For example, referring to fig. 1 and 4, when the cleaning apparatus 1 encounters an obstacle in the vicinity of the first module 15 during movement, the first cleaning frame 16 is more likely to contact the obstacle than the main housing 11 and collide with the obstacle. For example, the cleaning device 1 may clean a surface to be cleaned provided with a frame, and when the first cleaning frame 16 collides with an obstacle (frame) first, the control module in the cleaning device 1 will change the traveling state of the cleaning device 1 in time according to the collision information. For example, the cleaning device 1 is provided with a pressure detection component, the collision of the first cleaning frame 16 with the obstacle (frame) changes the pressure between the cleaning device 1 and the surface to be cleaned, and the control module can change the traveling state of the cleaning device 1 according to the pressure change information between the cleaning device 1 and the surface to be cleaned, and the detection can be referred to as "edge collision detection", but is not limited thereto. Therefore, the arrangement can reduce the risk of direct collision between the main housing 11 and the obstacle, so as to avoid the obstacle from causing serious scratch and other damages to the surface of the main housing 11, which is beneficial to maintaining the aesthetics of the main housing 11. For example, the travel state includes a travel direction.

For example, referring to fig. 1, 4-5, similar to the first cleaning rack 16, the second cleaning rack 18 may also perform "edge strike detection" on the cleaning apparatus 1. At least a portion of the second cleaning frame 18 protrudes with respect to the main casing 11, i.e., such that at least a portion of the outermost boundary line of the second cleaning frame 18 is located outside the outermost boundary line of the main casing 11. Therefore, when the size of the second cleaning frame 18 is increased, the size of the main housing 11 is not increased, thereby making it possible to make the design of the cleaning apparatus 1 more flexible and to improve the cleaning efficiency of the cleaning apparatus 1. Meanwhile, the second cleaning frame 18 is more likely to contact obstacles near the second module 17 than the main housing 11, so that the risk of direct collision between the main housing 11 and the obstacles can be reduced, the surface of the main housing 11 is prevented from being damaged by the obstacles, such as severe scratch, and the attractiveness of the main housing 11 is maintained.

For example, referring to fig. 6 to 8, the second protrusion 20 includes a first protrusion sub-portion 21, a second protrusion sub-portion 22, and a third protrusion sub-portion 23, the first protrusion sub-portion 21 and the second protrusion sub-portion 22 are disposed opposite to each other in the second direction X, and the third protrusion sub-portion 23 is located between the first protrusion sub-portion 21 and the second protrusion sub-portion 22. For example, the third projecting sub-portion 23 is disposed opposite to the first projecting portion 19 in the first direction Y.

For example, referring to fig. 6 to 8, the first protrusion sub-portions 21 and the second protrusion sub-portions 22 are oppositely disposed in the second direction X. For example, the first convex sub-portion 21 may be of a symmetrical structure with the second convex sub-portion 22, i.e., the first convex sub-portion 21 is the same size as the second convex sub-portion 22. The third protrusion sub-portion 23 and the first protrusion 19 are respectively located at opposite ends of the case assembly 10. For example, in the first direction Y, the maximum dimension of the third projecting sub-portion 23 is larger than the maximum dimension of the first projecting sub-portion 21 projecting from the main casing 11. For example, the maximum dimension of the third convex sub-portion 23 in the first direction Y is larger than the maximum dimension of the first convex sub-portion 21 or the second convex sub-portion 22 in the second direction X. For example, the third protrusion sub-portion 23 may be provided with other components of the housing assembly 10 to meet the functional requirements of the cleaning device 1, but is not limited thereto.

Thereby, the second cleaning rack 18 can be made to have good cleaning ability, and protection of the main casing at the time of "edge impact detection" of the cleaning apparatus 1 can be achieved.

For example, referring to fig. 6-8, the collision detecting member 24 is disposed at an end of the main housing 11 remote from the first module 15. For example, the collision detecting component 24 and the main housing 11 may be movably connected, that is, at least some components of the collision detecting component 24 may be subjected to a position change relative to the main housing 11 under the action of an external force, and the position change is not destructive. When the external force acting on the collision detecting assembly 24 is cancelled, at least some of the components of the collision detecting assembly 24 can be restored to the initial state. For example, the collision detecting assembly 24 may be connected to the main housing 11 by an elastic connection member, but is not limited thereto. For example, the elastic connection member may include a spring, a spring sheet, etc., and the embodiment of the present invention is not limited to the connection manner of the collision detection assembly 24 and the main housing 11.

For example, referring to fig. 6 to 8, an orthographic projection of the portion of the second cleaning frame 18 beyond the main housing 11 on the plane P (shown in fig. 4) may be the third protruding sub-portion 23, and the portion of the second cleaning frame 18 beyond the main housing 11 may be the support plate 25. For example, the collision detecting assembly 24 may be at least partially mated with the tray 25 via a plug-in structure 245. Based on the plug structure 245, at least some components of the collision detecting assembly 24 may move relative to the pallet 25 in the first direction Y, the second direction X, and the third direction Z relative to the pallet 25.

For example, referring to fig. 6 to 8, by disposing at least some components of the collision detecting member 24 on the side of the tray 25 away from the second cleaning frame 18, the space of the cleaning apparatus 1 in the first direction Y and the second direction X can be effectively utilized. With the arrangement, good matching among the size of the second cleaning frame 18, the size of the supporting plate 25 and the collision detection assembly 24 can be realized, and the size of the second cleaning frame 18 can be increased as much as possible to keep a good cleaning effect; while also enabling the collision detecting assembly 24 to project relative to the main housing 11 at an end remote from the first cleaning rack 16 to achieve "collision detection"; and so that at least part of the orthographic projection of the second cleaning frame 18 on the plane P (as shown in fig. 4) is outside the orthographic projection of the main housing 11 on the plane P to achieve "edge strike detection".

The utility model provides a housing assembly 10 is favorable to optimizing the size cooperation condition of each part among the housing assembly, increases effective clean area to improve clean efficiency, and realize "collision detection" and "bump limit detection"; meanwhile, the risk of scratching between the main casing body 11 and the external boundary can be effectively reduced, so that the probability of surface defects such as scratches is reduced, and the attractiveness of the cleaning device 1 is improved.

FIG. 9 is a partial schematic view of the impingement shell coupled to the main housing in the cleaning apparatus shown in FIG. 1; figure 10 is a schematic view of another of the housing assemblies in the cleaning device shown in figure 1.

For example, referring to fig. 6-8, to facilitate edge strike detection and protection of the main housing during an edge strike, the orthographic projection of the edge 161 of the first cleaning frame 16 in the first direction Y, away from the second cleaning frame 18, onto the plane P is outside the orthographic projection of the main housing 11 onto the plane P (as shown in fig. 4).

For example, referring to fig. 6-8, to facilitate edge impact detection and protection of the main housing during edge impact, the maximum dimension L1 of the first cleaning rack 16 in the second direction X is greater than the maximum dimension L2 of the main housing 11 in the second direction X. The first direction Y is a direction in which the first cleaning rack 16 points to the second cleaning rack 18, the second direction X is perpendicular to the first direction Y, and both the first direction Y and the second direction X are parallel to the plane P.

For example, referring to fig. 6-8, in the first direction Y, an orthographic projection of the main housing 11 on the plane P is a dashed line portion in the housing assembly 10 in fig. 6, and an orthographic projection of an edge 161 of the first cleaning rack 16 distal from the second cleaning rack 18 on the plane P is located outside the dashed line proximal to the first cleaning rack 16. In the second direction X, the maximum dimension of the first cleaning frame 16 is L1, the maximum dimension of the main housing 11 is L2, and L1 is greater than L2. Thus, when the size of the first cleaning frame 16 is increased, the maximum size of the main housing 11 may not be changed to flexibly increase the cleaning efficiency of the cleaning device; meanwhile, when an obstacle exists at the end of the housing assembly 10 close to the first cleaning frame 16, the first cleaning frame 16 may contact with the obstacle at the end far from the second cleaning frame 16 in the first direction Y and the end in the second direction X, respectively, so as to avoid surface damage such as scratching of the main housing 11 by the obstacle.

For example, as shown in fig. 6, an orthographic projection of an edge 181 of the second cleaning rack 18 in the first direction Y, which is distant from the first cleaning rack 16, on the plane P is located outside an orthographic projection of the main housing 11 on the plane P (shown in fig. 4).

For example, as shown in fig. 6, the maximum dimension L3 of the second cleaning frame 18 in the second direction X is larger than the maximum dimension L2 of the main housing 11 in the second direction X.

For example, referring to fig. 6 and 8, in the first direction Y, an orthographic projection of an edge 161 of the second cleaning rack 18 on the plane P, the edge being away from the first cleaning rack 16, is located outside an imaginary line close to the second cleaning rack 18. In the second direction X, the maximum dimension of the second cleaning frame 18 is L3, the maximum dimension of the main housing 11 is L2, and L3 is greater than L2. Therefore, the size of the second cleaning frame 18 can be flexibly adjusted to increase the cleaning efficiency of the cleaning device; meanwhile, when an obstacle exists at one end of the housing assembly 10 close to the second cleaning frame 18, the second cleaning frame 18 may contact the obstacle at one end far away from the first cleaning frame 16 in the first direction Y and at the second direction X, respectively, so as to avoid surface damage such as scratch and rubbing of the main housing 11 by the obstacle.

For example, referring to fig. 6-7, the first cleaning rack 16 includes a first protrusion 19, the first protrusion 19 is located at an end of the first cleaning rack 16 away from the second cleaning rack 18, and the first protrusion 19 protrudes from the main housing 11. The maximum distance H1 between the orthographic projection of the edge of the first projection 19 away from the second cleaning frame 18 on the plane P (as shown in fig. 4) and the orthographic projection of the main housing 11 on the plane P is 3-20mm.

For example, referring to fig. 6 to 7, the first protrusion 19 may be a portion with oblique lines in fig. 6 adjacent to the first cleaning rack 16. The first protrusion 19 protrudes from the first cleaning frame 16, and the first protrusion 19 is circumferentially surrounded along the first cleaning frame 16 and has a shape of a ring with a notch. Notched rings include, but are not limited to, C-shapes. At least part of the orthographic projection of the main housing 11 on the plane P (as shown in fig. 4) falls into the orthographic projection of the first cleaning rack 16 on the plane P, and the maximum distance H1 between the orthographic projection of the edge of the first projecting portion 19 away from the second cleaning rack 18 on the plane P and the orthographic projection of the main housing 11 on the plane P is 3-20mm.

For example, referring to fig. 6-7, the maximum distance H1 between the orthographic projection of the edge of the first projection 19 away from the second cleaning frame 18 on the plane P and the orthographic projection of the main housing 11 on the plane P is 3-15mm. For example, the above dimension may be 5 to 15mm. For example, the above dimensions may be 6-18mm. For example, the above dimension may be 5 to 10mm. For example, the above dimension may be 4 to 9mm. For example, the above size may be 3 to 8mm, but is not limited thereto. Therefore, the first cleaning frame 16 can have good cleaning capability, and the scratch phenomenon generated when the main casing 11 collides with an obstacle can be reduced.

For example, referring to fig. 6 and 8, the second cleaning rack 18 includes a second protrusion 20, the second protrusion 20 is located at an end of the second cleaning rack 18 away from the first cleaning rack 16, and the second protrusion 20 protrudes from the main housing 11. The maximum distance H2 between the orthographic projection of the edge of the second projection 20 away from the first cleaning frame 16 on the plane P (as shown in fig. 4) and the orthographic projection of the main housing 11 on the plane P is 3-20mm.

For example, referring to fig. 6 and 8, the second protrusion 20 may be a portion with a zigzag line in fig. 6 adjacent to the second cleaning rack 18. The second protrusion 20 protrudes from the second cleaning frame 18, the second protrusion 20 surrounds along the circumferential direction of the second cleaning frame 18, and the maximum dimension of the second protrusion 20 in the first direction Y is greater than the maximum dimension of the second protrusion 20 in the second direction X. At least part of the orthographic projection of the main housing 11 on the plane P (as shown in fig. 4) falls into the orthographic projection of the second cleaning frame 18 on the plane P, and the maximum distance H2 between the orthographic projection of the edge of the second projecting portion 20 away from the first cleaning frame 16 on the plane P and the orthographic projection of the main housing 11 on the plane P is 3-20mm.

For example, referring to fig. 6 and 8, the maximum distance H2 between the orthographic projection of the edge of the second projection 20 away from the first cleaning frame 16 on the plane P and the orthographic projection of the main housing 11 on the plane P is 3-15mm. For example, the above dimension may be 5 to 15mm. For example, the above dimension may be 6-16mm. For example, the above dimension may be 5 to 10mm. For example, the above dimension may be 4 to 13mm. For example, the above size may be 7-12mm, but is not limited thereto. Therefore, the second cleaning frame 18 can have good cleaning capability, and the scratch phenomenon generated when the main casing 11 collides with an obstacle can be reduced.

For example, in some embodiments, the maximum distance H2 is greater than the maximum distance H1.

For example, referring to fig. 6-8, a maximum dimension L4 of the collision detecting assembly 24 in the second direction X is greater than a maximum dimension L3 of the second cleaning rack 18 in the second direction X, and at least a portion of an orthographic projection of an edge of the second cleaning rack 18 distal from the first cleaning rack 16 on the plane P falls within an orthographic projection of the collision detecting assembly 24 on the plane P.

For example, referring to fig. 6 to 8, when the maximum dimension L4 of the collision detecting assembly 24 in the second direction X is greater than the maximum dimension L3 of the second cleaning frame 18 in the second direction X, it is possible to reduce the collision of the main housing 11 with an obstacle by the collision detecting assembly 24 coming into contact with and colliding with the obstacle when the housing assembly 10 encounters the obstacle in the vicinity of the collision detecting assembly 24 in the second direction X. Meanwhile, the collision detecting member 24 protrudes in the first direction Y with respect to the main housing 11, whereby it is possible to reduce the collision of the main housing 11 with an obstacle in the first direction Y. For example, the maximum size of the collision detecting assembly 24 in the first direction Y may be determined according to actual design requirements to adapt to different environmental requirements.

For example, referring to fig. 6-9, the impact detection assembly 24 includes an impact housing 26 and a first sensor 27 (shown in fig. 8), the impact housing 26 being located outside the side portion 13 of the main housing 11 and forming a mounting cavity 28 (shown in fig. 8) with the main housing 11.

For example, referring to fig. 6-9, the first sensor 27 is configured to sense whether a collision has occurred. For example, a first sensor 27 is disposed on the carriage 25 and within the mounting cavity 28.

For example, referring to fig. 6 to 9, since the main housing 11 and the collision detecting assembly 24 have a size difference in both the first direction Y and the second direction X, a space enclosed by the collision housing 26 of the collision detecting assembly 24 and the main housing 11 may form the mounting cavity 28. For example, some components in the cleaning device 1 may be disposed in the mounting cavity 28 to improve the space utilization of the mounting cavity 28, so that the space arrangement of the main housing 11 is more reasonable, and the overall size is prevented from being too large. Meanwhile, the size of the mounting cavity 28 can be measured according to the maximum size of the second cleaning frame 18, so that the size of the second cleaning frame 18 can be maximized while meeting the requirement of collision detection, thereby improving the cleaning efficiency and the cleaning effect.

For example, referring to fig. 6-10, the cleaning device 1 may include a walking module by which the cleaning device 1 is moved under the control of a control module 29 (shown in fig. 10), and the first sensor 27 may recognize the position information of the crash can 26 with respect to the main housing 11. For example, when the cleaning device 1 is moved to the rim of the surface to be cleaned, the collision detecting assembly 24 will collide with the rim around it, there will be a change in position between the collision housing 26 and the main housing 11 which can be sensed by the first sensor 27, and the first sensor 27 can send a signal to the control module to cause the control module to change the direction of movement of the cleaning device 1. For example, the first sensor 27 may be provided in the mounting cavity 28 to perform good position detection of the position of the crash case 26 with respect to the main housing 11 and to improve the utilization of the space of the mounting cavity 28. For example, other components in the cleaning device 1 may be disposed in the mounting cavity 28 according to design requirements, and are not limited in this regard.

For example, referring to fig. 1, 4 and 8, the housing assembly 10 further includes a step-on-empty detection member 32 (shown in fig. 4), the step-on-empty detection member 32 being located at a corner portion 189 of the end of the main housing 11 where the second cleaning rack 18 is provided, the step-on-empty detection member 32 being configured to perform step-on-empty detection of the housing assembly 10. The second cleaning rack 18 includes a notch 185, and the step-empty detecting member 32 is disposed in the notch 185. The orthographic projection of the step-empty detection member 32 on the plane P at least partially overlaps with the orthographic projection of the collision housing 26 on the plane P, at least part of the collision housing 26 being located outside the pallet 25.

For example, referring to fig. 1, 4 and 8, the step-on-empty detection section 32 may perform step-on-empty detection on the cleaning apparatus 1. For example, when the cleaning apparatus 1 moves to the edge of the surface to be cleaned, or when one end of the cleaning apparatus 1 is in a step-on-empty state, the step-on-empty detection part 32 may feed back step-on-empty information of the cleaning apparatus 1 to the control module to change the traveling state of the cleaning apparatus 1 by the control module, thereby playing a role of monitoring the step-on-empty signal and protecting the cleaning apparatus 1.

For example, referring to fig. 1, 4, and 8, at least a portion of the step-on-empty detecting member 32 is located outside the collision case 26 to improve the accuracy of the step-on-empty detection. The step-on-empty detection part 32 is located in the notch 185 of the second cleaning frame 18, and the orthographic projection of the step-on-empty detection part 32 on the plane P at least partially falls into the orthographic projection of the collision housing 26 on the plane P, so that the sizes of the cleaning device 1 in the first direction Y, the second direction X and the third direction Z can be saved, good space utilization rate is realized, and the space arrangement is more reasonable.

For example, referring to fig. 1, 4 and 8, the housing assembly 10 may include 2 step-empty detection parts 32, the corner parts 189 including a first corner part 33 and a second corner part 34 opposite in the second direction X, the 2 step-empty detection parts 32 being located at the first corner part 33 and the second corner part 34, respectively.

For example, referring to fig. 1, 4 and 8, the first corner 33 and the second corner 34 may be two corners of the end of the housing assembly 10 away from the first cleaning rack 16. Thus, the 2 step-on-empty detecting members 32 can function together to detect step-on-empty of the cleaning device 1 in a plurality of directions (for example, four directions of front, rear, left, and right) to improve the performance of the cleaning device 1.

The embodiment of the utility model provides a cleaning device 1 is still provided, including the casing assembly 10 in any embodiment of the aforesaid to and inside casing 35, go out fan housing 37 and fan 39.

For example, referring to fig. 2-5, the inner housing 35 is located on the first side 121 of the main housing 11 and includes an air inlet cover 36; the air outlet cover 37 is connected with the air inlet cover 36 to form an accommodating cavity 38; a fan 39 is located within the receiving chamber 38. The main housing 11, the inner housing 35, the fan 39, and the air outlet cover 37 are sequentially arranged in the third direction Z and constitute a negative pressure mechanism 40, and the negative pressure mechanism 40 is configured to form a negative pressure in the housing assembly 10.

For example, referring to fig. 2-5, the inner housing 35 is connected to the main housing 11 to form an air inlet chamber 41, the air outlet cover 37 includes an air outlet channel 42, the air outlet channel 42 is communicated with the outside of the housing assembly 10 to form an air outlet chamber 43, and the air inlet chamber 41, the accommodating chamber 38 and the air outlet chamber 43 are communicated to form an air chamber 44.

For example, referring to fig. 2-5, the housing assembly 10 further includes a second sensor (not shown) configured to detect air pressure in the wind cavity 44, the third direction Z being perpendicular to the plane P. For example, the second sensor may be disposed in the wind cavity. For example, the second sensor is connected to the control module 29.

For example, referring to fig. 2-5, the inner housing 35 is fixedly attached to the main housing 11 to form an air intake chamber 41 therebetween. For example, the bottom 12 of the main housing 11 is provided with through holes to allow airflow into the air intake chamber 41. For example, the air inlet cover 36 can be formed by a portion of the inner housing 35 and can be sealingly connected to the air outlet cover 37 to form the receiving cavity 38. For example, the wind outlet cover 37 may include a wind outlet channel 42, so that the airflow in the accommodating cavity 38 may be circulated to the outside of the housing assembly 10, and at least a portion of the wind outlet channel 42 may serve as a wind outlet cavity 43. The air inlet chamber 41, the accommodating chamber 38 and the air outlet chamber 43 of the housing assembly 10 communicate to form an air flow passage.

For example, referring to fig. 2-5, a fan 39 is connected to the control module 29 (shown in fig. 10) and is operated under the drive of the control module 29 to cause the negative pressure mechanism 40 to draw an airflow (e.g., air) between the housing assembly 10 and the surface to be cleaned. The air flow enters the air inlet chamber 41, passes through the accommodating chamber 38 and is discharged to the outside of the housing assembly 10 along the air outlet channel 42. In this process, a negative pressure can be formed between the housing assembly 10 and the surface to be cleaned, so that the cleaning device 1 can be brought into close proximity to the surface to be cleaned.

For example, referring to fig. 2-5, the air pressure in the air chamber 44 of the cleaning apparatus 1 is maintained in a less error interval during normal cleaning operation of the cleaning apparatus 1. For example, referring to the description of the above embodiment, when the first module 15 collides with an obstacle, the air pressure of the air chamber 44 changes. Thus, the second sensor can detect the air pressure change in the air cavity 44, and the cleaning device 1 can be detected by the first module 15, and meanwhile, the embodiment of the present invention is not limited to the types of the first sensor 27 (as shown in fig. 8) and the second sensor.

For example, the cleaning device 1 may further comprise an upper housing assembly disposed at a side of the housing assembly 10 away from the second module 17 thereof in the third direction Z. For example, the housing assembly 10 may be referred to as a lower housing assembly. For example, the upper housing assembly is removably connected to the housing assembly 10 and forms a complete sealing structure. For example, the upper housing assembly may include an upper housing body, a water tank, a nozzle, an air pressure sensor, and other components that are sufficient for operation of the cleaning device 10.

For example, the walking module in the cleaning device 1 may comprise walking members, which may comprise tracks and walking wheel sets. The cleaning apparatus 1 may further comprise a drive module, for example, the drive module may comprise at least one drive motor and at least one reduction gearbox. For example, the drive module may include a first motor and a second motor. For example, a first motor is disposed in the cavity 14 and close to the first module 15, and the first motor can drive the first module to rotate under the control of the control module, so that the first module 15 drives the cleaning device 1 to perform a curved motion. For example, at least a part of the second motor is disposed in the cavity 14 and close to the second module 17, and the second motor can drive the second module 17 to rotate under the control of the control module, so that the second module 17 drives the cleaning device 1 to perform linear motion. Thus, the cleaning device 1 can realize linear motion and curvilinear motion under the combined action of the first electrode and the second motor.

For example, the traveling wheel set may include two traveling wheels spaced apart along the second direction X, but is not limited thereto. For example, the number of road wheels in a road wheel set may depend on the actual design requirements. At least a portion of the running wheels is located on the second side 122 of the base 12 to meet the running wheels' contact with the surface to be cleaned.

The embodiment of the utility model provides a cleaning device 1 is favorable to optimizing the size cooperation condition of each part among the casing assembly, increases effective clean area to improve clean efficiency, and realize "collision detection" and "bump limit detection"; meanwhile, the risk of scratching between the main shell 11 and the external boundary can be effectively reduced, so that the probability of surface defects such as scratches is reduced, and the attractiveness of the cleaning device 1 is improved.

For example, the cleaning device 1 may be adapted for surface cleaning in a variety of situations. For example, for cleaning on a horizontal surface, such as a floor, a table, a carpet, etc., the negative pressure mechanism 40 can increase the pressure between the cleaning device 1 and the horizontal surface, such as increasing the friction force and improving the cleaning effect. For example, in some embodiments, when the cleaning device 1 is used for cleaning on a horizontal surface, the negative pressure mechanism 40 may not be provided. For example, the cleaning device 1 may also be used for cleaning on non-horizontal surfaces, such as glass, walls, cabinets, etc., and the negative pressure mechanism 40 may make the cleaning device 1 be attached to the non-horizontal surfaces.

For example, the cleaning device may be a cleaning robot including a window wiping robot, a sweeping robot, a mopping robot, a sweeping and mopping integrated robot, and the like, and the surface to be cleaned includes a window, a wall surface, and the like, but is not limited thereto. For example, the window may be a framed window or a frameless window. For example, the framed window may be a home window, the frameless window may be a large french window, and so on.

The above embodiments are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, and all should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
