[0042] Figure 1 A schematic diagram showing a partial structure of a sweeping robot in an embodiment of the present application; Figure 2 A schematic structural diagram of a fan duct assembly in an embodiment of the present application is shown; for ease of description, the accompanying drawings only show structures related to the embodiment of the present application.

[0043] Referring to the drawings, a sweeping robot 100 provided in one embodiment of the present application includes a housing 10 and a fan duct assembly 20 and a pressing member 30 disposed inside the housing 10, wherein the fan duct assembly 20 includes a fan structure 21 and a front duct structure 22. Specifically, the housing 10 includes an upper housing (not shown) and a lower housing, the upper housing and the lower housing are combined to form a receiving cavity of the housing 10, the fan duct assembly 20 is located in the receiving cavity, and is installed on the lower housing. Specifically, the airflow flows from the front end of the fan structure 21 to the rear end of the fan structure 21, and the front duct structure 22 is located at the front end of the fan structure 21 along the airflow direction.

[0044] like Figure 3 As shown, the casing 10 has a supporting surface 11, the fan structure 21 includes a fan housing 211, the fan housing 211 is placed on the supporting surface 11 of the casing 10, the front air duct structure 22 is located on the side of the fan structure 21 away from the supporting surface 11, the front air duct structure 22 includes a front air duct housing 221, and the front air duct housing 221 is press-fitted with the fan housing 211 as a whole.

[0045] Specifically, a fan air inlet 2111 is provided on the side of the fan housing 211 facing away from the support surface 11, a first press-fitting portion 2112 is provided on the fan housing 211 around the fan air inlet 2111, an air duct outlet is provided on one end of the front air duct housing 221, a second press-fitting portion 2211 is provided on the front air duct housing 221 around the air duct outlet, and the front air duct housing 221 and the fan housing 211 are press-fitted into one body through the first press-fitting portion 2112 and the second press-fitting portion 2211. In this way, the fan air inlet 2111 can be accurately aligned with the air duct outlet.

[0046] Please refer again Figure 1 and Figure 2 , wherein two ends of the pressing member 30 are respectively connected to the front air duct housing 221 and the housing 10 to apply a pressing force to the front air duct housing 221 in a direction toward the supporting surface 11 .

[0047] In this way, by placing the fan housing 211 on the support surface 11 of the housing 10, and pressing the front air duct housing 221 onto the fan housing 211 toward the support surface 11, and then connecting the front air duct housing 211 to the housing 10 through the pressing member 30, the front air duct housing 221 is pressed toward the support surface 11, thereby completing the installation of the fan duct assembly 20 relative to the housing 10. The sweeping robot 100 of the present application does not need to use bolts and other connecting members to connect the fan structure 21 to the housing, the front air duct structure 22 to the fan structure 21, and the front air duct structure 22 to the housing for multiple operations before completing the assembly of the fan duct assembly 20 relative to the housing 10. Instead, it is only necessary to press-fit the front air duct housing 221 to the fan housing 211, and then connect the pressing member 30 to the housing 10, so that the front air duct structure 22 together with the fan structure 21 can be assembled to the housing 10, thereby simplifying the assembly structure and assembly process, and making the assembly efficiency high.

[0048] In the embodiment of the present application, the fan structure 21 is a centrifugal fan. In other embodiments, it may be other types of fans, which is not limited here.

[0049] In some embodiments, the front air duct structure 22 further includes a crimping portion 222 disposed on the outside of the front air duct housing 221, and the pressing member 30 includes a crimping end and a connecting end, the crimping end is pressed against the side of the crimping portion 222 away from the support surface 11, and the connecting end is connected to the housing 10. Since the crimping end is pressed against the side of the crimping portion away from the support surface 11, a more reliable pressing force can be provided for the front air duct housing 221, ensuring that the fan air duct assembly 20 is reliably installed relative to the housing 10.

[0050] Furthermore, the crimping end is located on the side of the crimping portion 222 close to the support surface 11 along the clamping direction of the clamping member 30. Compared with the crimping end being located on the side of the crimping portion 222 away from the support surface 11, being located on the same side as the support surface 11 can improve the convenience of assembly operation and improve assembly efficiency. In other embodiments, the crimping end may also be located on the side of the crimping portion 222 away from the support surface 11 along the clamping direction of the clamping member 30, which is not limited here.

[0051] Furthermore, the crimping portion 222 has a through hole 2221, and the connecting end of the pressing member 30 is passed through the through hole 2221 and connected to the housing 10. In this way, the process of the pressing member 30 pressing the crimping portion 222 can be simplified. In one embodiment, the pressing member 30 includes a bolt, which passes through the through hole and is connected to the corresponding threaded hole of the housing 10.

[0052] In some embodiments, the side of the crimping portion 222 facing the support surface 11 is supported on the housing 10. In this way, the crimping portion 222 can be effectively supported, and a preset amount of compression can be provided for the compression member 30 to avoid excessive force on the crimping portion 222 during the compression process using the compression member 30, thereby causing damage to the front air duct structure 22.

[0053] Furthermore, the housing 10 also includes a protruding structure 12 protruding from the support surface 11, and the protruding structure 12 supports the crimping portion 222. The manner of providing the protruding structure 12 from the support surface 11 to support the crimping portion 222 can ensure that the crimping portion 222 is reliably pressed toward the support surface 11 under the pressing action of the pressing member 30, thereby improving the pressing accuracy. Specifically, the protruding structure 12 may include a boss, and more specifically, reinforcing ribs are provided around the boss. In some preferred embodiments, the protruding structure 12 includes a cylindrical boss. The manner of providing the boss is simpler, which simplifies the manufacturing process of the housing 10.

[0054] Furthermore, the connection end of the pressing member 30 is connected to the protruding structure 12 . In this way, it is possible to avoid connecting the connection end through other parts of the housing 10 , simplify the structure of the housing 10 , and enable the crimping portion 222 to be accurately supported on the protruding structure 12 .

[0055] In some embodiments, the crimping parts 222 include at least two, and the at least two crimping parts 222 are located on both sides of the front air duct housing 221 along the first direction parallel to the support surface 11. In this way, the two sides of the front air duct housing 221 can be evenly stressed, and the pressing effect is better.

[0056] In some embodiments, the crimping portion 222 is convexly disposed on the outer surface of the front air duct housing 10. In this way, it is more convenient for the pressing member 30 to cooperate and press the crimping portion 222 without affecting the front air duct housing 10. Specifically, the crimping portion 222 is convexly disposed on the outer surface of the front air duct housing 10 along the first direction.

[0057] Please refer again Figure 3 In some embodiments, the front air duct housing 221 includes a first front air duct housing 2212 and a second front air duct housing 2213. The first front air duct housing 2212 and the second front air duct housing 2213 can be matched in the second direction to form an airflow cavity of the front air duct housing 221. The crimping portion 222 includes a first crimping portion 2222 provided on the first front air duct housing 2212 and a second crimping portion 2223 provided on the second front air duct housing 2213. The first crimping portion 2222 is closer to the support surface 11 than the second crimping portion 2223, wherein the second direction intersects with the direction parallel to the support surface. The first crimping portion 2222 is supported on the housing 10, the crimping end of the pressing member 30 is pressed against the side of the second crimping portion 2223 away from the support surface 11, and the connecting end is connected to the housing. In this way, the pressing member 30 can press the pressing portion 222 onto the housing 10 while also completing the locking between the first front air duct housing 2212 and the second front air duct housing 2213 , thereby simplifying the structure of the front air duct structure 22 .

[0058] In another embodiment, the front air duct structure 22 further includes a locking member, the crimping end of the pressing member 30 is pressed against the side of the second crimping portion 2223 away from the support surface 11, the connecting end is connected to the housing 10, and the locking member includes a locking position that cooperates with the pressing member 30 to lock the first front air duct housing 2212 with the second front air duct housing 2213. Specifically, the locking member includes a nut, the pressing member 30 includes a bolt, the first crimping portion 2222 and the second crimping portion 2223 are both provided with sub-through holes, the bolt passes through two sub-through holes and is connected to the threaded holes corresponding to the housing 10, the nut cooperates with the bolt, and abuts against the surface of the first crimping portion 2222 facing the support surface 11 to lock the first front air duct housing 2212 with the second front air duct housing 2213.

[0059] In some embodiments, the first press-fitting portion 2112 includes a press-fitting protrusion, and the second press-fitting portion 2211 includes a press-fitting groove, and the outer wall of the press-fitting protrusion is press-fitted with the inner wall of the press-fitting groove. The fan structure 21 is heavier than the front air duct structure 22 and has a higher structural strength. Therefore, by setting the press-fitting protrusion 2212 on the fan housing 211 and setting the press-fitting groove on the front air duct housing 221, damage to the front air duct housing 221 during the press-fitting process can be avoided, and the press-fitting is more convenient.

[0060] Furthermore, the fan duct assembly 20 further includes a sealing member 23, which is sleeved on the outer side of the press-fitting protrusion to seal between the front duct housing 221 and the fan housing 211 when the second press-fitting portion 2211 is press-fitted with the first press-fitting portion 2112. Since the pressing member 30 provides a pressing force for the front duct housing 221 toward the supporting surface 11, the sealing member 23 is always in a pressed state, so that the sealing effect is better and the sealing is more reliable.

[0061] In some embodiments, the fan structure 21 further includes a buffer cushion 212, which is disposed between the fan housing 211 and the support surface 11. The buffer cushion 212 can alleviate the noise generated by the fan structure 21 directly contacting the housing 10 during movement, and can also protect the fan housing 211 and the housing 10 from being damaged by excessive compression force during the compression process. Specifically, the buffer cushion 212 includes an elastic cushion, and in some embodiments, the buffer cushion 212 includes a rubber cushion or a silicone cushion.

[0062] The cleaning robot 100 provided in the embodiment of the present application has the following beneficial effects:

[0063] By placing the fan housing 211 on the support surface 11 of the housing 10, and pressing the front air duct housing 221 onto the fan housing 211 toward the support surface 11, and then connecting the front air duct housing 211 to the housing 10 through the pressing member 30, the front air duct housing 221 is pressed toward the support surface 11, thereby completing the installation of the fan duct assembly 20 relative to the housing 10. The sweeping robot 100 of the present application does not need to use bolts and other connecting members to connect the fan structure 21 to the housing, the front air duct structure 22 to the fan structure 21, and the front air duct structure 22 to the housing for multiple operations before completing the assembly of the fan duct assembly 20 relative to the housing 10. Instead, it is only necessary to press-fit the front air duct housing 221 to the fan housing 211, and then connect the pressing member 30 to the housing 10, so that the front air duct structure 22 together with the fan structure 21 can be assembled to the housing 10, thereby simplifying the assembly structure and assembly process, and making the assembly efficiency high.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
