It should be noted that the main body comprises the combined outer shell, inner container, and door frame structure of the cleaning machine, and the door is rotatably mounted to the door frame structure via a hinge. This main body is a conventional structure for cleaning machines and will not be described in detail here.
[0049] Figure 1 The schematic diagram of the structure of the door body provided in the embodiment of the present application is shown. Figure 1 As shown, the door body includes a door body main body 1, an upper door panel 2, a lower door panel 3, a decorative part 4 and a top panel 5, wherein the rear side of the door body main body 1 has a rotating part (not shown in the figure) that is rotatably connected to the lower end of the fuselage, and the end of the door body main body 1 away from the rotating part is the free end of the door body main body 1, and the front side of the door body main body 1 has a groove 11 extending in the left and right directions and opening forward. With the groove 11 as a dividing line, the upper door panel 2 and the decorative part 4 are installed on the side of the door body main body 1 close to the free end, the lower door panel 3 is installed on the side of the door body main body 1 close to the rotating part, and the top panel 5 is installed on the free end of the door body main body 1.
[0050] It should be noted that the front and rear sides of the door body 1 refer to the two sides in the thickness direction of the door body 1, and when the door body closes the cleaning cavity, the front side of the door body 1 is in the same direction as the front side of the machine body, and the rear side of the door body 1 is in the same direction as the rear side of the machine body; the left and right sides of the door body 1 refer to the left and right sides of the user when the user is facing the cleaning machine.
[0051] Figure 2 A schematic diagram of the partial structure of the door body 1 provided in an embodiment of the present application in one direction is shown.
[0052] Figure 3 A schematic diagram of the partial structure of the door body 1 provided in an embodiment of the present application in another direction is shown.
[0053] Figure 4The schematic diagram of the structure of the handle structure 6 provided in the embodiment of the present application in one direction is shown. Figures 2 to 4 As shown, the door body also includes a handle structure 6, wherein the first side wall 11a of the groove 11 away from the rotating part has a notch 111, the handle structure 6 has a hand-grip groove 60 with an opening facing the rotating part, and the left and right sides of the handle structure 6 have second guide surfaces 62. The handle structure 6 is assembled on the door body 1 from back to front in a manner that the second guide surface 62 and the first guide surface 131 slide together, and when the handle structure 6 is assembled, the opening of the hand-grip groove 60 engages with the notch 111 to form an operating channel for the hand to extend into. This design facilitates the alignment and installation of the handle structure 6 through the guide and limiting cooperation of the second guide surface 62 and the first guide surface 131, improves the assembly efficiency of the handle structure 6, and can also prevent the handle structure 6 from colliding with foreign objects, making it convenient for the user to reach into the hand-grip groove 60 and pull the door body 1 through the handle structure 6.
[0054] The groove 11 also has a bottom wall 11b and a second side wall 11c, wherein the bottom wall 11b is connected to the first side wall 11a and is approximately 90° to the first side wall 11a, and the second side wall 11c is connected to the bottom wall 11b and the angle between the bottom wall 11b is greater than 90°, so as to increase the opening of the groove 11 and facilitate the user's hand to pass through the groove 11 smoothly into the operating channel.
[0055] In this embodiment, the door body 1 has guide protrusions 13 extending in the front-to-back direction on both the left and right sides of the notch 111. The opposing surfaces of the two guide protrusions 13 form first guide surfaces 131. This arrangement increases the length of the first guide surfaces 131 in the direction from the rotating portion to the free end of the door body 1, allowing the two first guide surfaces 131 to form guide installation grooves to guide and position the handle structure 6, thereby improving the installation accuracy of the handle structure 6.
[0056] The guide protrusion 13 also has a support surface 132. The handle structure 6 has a first limiting protrusion, which has a first limiting surface 63 that mates with the support surface 132. The first limiting surface 63 cooperates with the support surface 132 to support the handle structure 6 and ensure its stability. In this embodiment, the handle structure 6 has first limiting protrusions on both its left and right sides. The surface of the first limiting protrusion facing the opening of the hand-grip slot 60 serves as the first limiting surface 63. Furthermore, the supporting surface 132 is perpendicularly connected to the first guide surface 131, and the first limiting surface 63 is perpendicularly connected to the second guide surface 62. When the handle structure 6 is inserted into the guide installation slot formed by the two first guide surfaces 131, the second guide surface 62 naturally slides with the first guide surface 131. During this process, pressing down on the handle structure 6 causes the first limiting surface 63 of the handle structure 6 to mate with the support surface 132, ensuring that the handle structure 6 is properly installed in its height direction. The handle structure 6 can then be pushed forward from back to front to be properly installed in the front-back direction.
[0057] Figure 5 FIG1 shows a cross-sectional view of the door body 1 and the handle structure 6 in an assembled state provided by an embodiment of the present application. Figure 5 Combine Figure 4 As shown, the handle structure 6 includes a front side wall 6a, a connecting wall 6b, a rear side wall 6c, a left side wall 6d, and a right side wall 6e. The front side wall 6a, the connecting wall 6b, and the rear side wall 6c are connected in sequence to form an inverted U-shaped structure. The left side wall 6d is connected to one end of the inverted U-shaped structure, and the right side wall 6e is connected to the other end of the inverted U-shaped structure. The front side wall 6a, the connecting wall 6b, the rear side wall 6c, the left side wall 6d, and the right side wall 6e are surrounded to form a hand-grip groove 60. This design makes the handle structure 6 as a whole roughly a box-shaped structure with one end open. When the handle structure 6 is in the assembled state, the front, rear, left, right, and side of the hand-grip groove 60 of the handle structure 6 near the free end of the door body 1 are all closed, which can improve the user's operating feel.
[0058] The handle structure 6 also includes a second limiting protrusion connected to the free end of the rear side wall 6c. The second limiting protrusion has a second limiting surface 64 that can abut against the rear side of the door body 1. When the handle structure 6 is assembled, the rear side wall 6c is correspondingly connected to the bottom wall 11b of the groove 11. Through the limited abutment of the second limiting surface 64 with the rear side of the door body 1, on the one hand, the installation of the handle structure 6 can be limited, ensuring the installation accuracy of the handle structure 6; on the other hand, it can also enable the rear side wall 6c of the handle structure 6 to be correspondingly connected to the bottom wall 11b of the groove 11, thereby making the rear wall surface of the hand-grip groove 60 and the inner surface of the bottom wall 11b of the groove 11 roughly form a seamless transition connection, which not only helps to improve the user's hand feel, but also prevents dust from accumulating at the connection, making it easier for users to clean the door body and improving the overall aesthetics of the product.
[0059] In this embodiment, the first limiting surface 63, the second guide surface 62 and the first guide surface 131 are arranged at 90° in pairs, and the second limiting surface 64 is directly connected to the first limiting surface 63. The second limiting surface 64 can also abut against the rear side surface of the guide protrusion 13, so that multi-directional limiting of the handle structure 6 can be achieved.
[0060] In order to increase the internal space of the hand-grip groove 60, the inner surface of the rear side wall 6c is an arc-shaped surface extending forward from the middle to the left and right sides, and the bottom wall 11b of the groove 11 corresponding to the rear side wall 6c of the hand-grip groove 60 is an arc-shaped surface extending forward from the middle to the left and right sides.
[0061] Figure 6 A structural schematic diagram of the door body 1 and the handle structure 6 provided in an embodiment of the present application in an assembled state is shown. Figure 7 It shows a schematic diagram of the structure of the handle structure 6 provided in the embodiment of the present application in another direction.

Part of the second connecting member 61 is detachably fixedly connected to the first connecting member 12 via fasteners, or part of the second connecting member 61 is detachably fixedly connected to the first connecting member 12 via a snap connection.
[0063] For the snap-fit connection solution, the first connector 12 has a buckle, and the second connector 61 has a buckle position that can cooperate with the buckle. The buckle is abutted against the buckle position to achieve the limited installation of the handle structure 6. For the fastener connection solution, the first connector 12 has a threaded hole 121, and the second connector 61 has a through hole 611. The fastener passes through the through hole 611 and is threadedly connected to the threaded hole 121, thereby achieving the limited installation of the handle structure 6.
[0064] In this embodiment, there are six second connectors 61, three of which are protruding from the outer surface of the connecting wall 6b, one second connector 61 is protruding from the outer surface of the left side wall 6d, one second connector 61 is protruding from the outer surface of the right side wall 6e, and one second connector 61 is protruding from the outer surface of the rear side wall 6c. Furthermore, there are eight first connectors 12, six of which are connected to the rear side of the door body 1 in the same layout as the second connectors 61, ensuring a one-to-one connection between the first connectors 12 and the second connectors 61; the other two first connectors 12 are located outside the first connectors 12 on the left and right sides of the notch 111.
[0065] Furthermore, two of the three second connecting members 61 located on the connecting wall 6b are detachably fixedly connected to the corresponding first connecting members 12 by snapping, and the remaining second connecting member 61 is detachably fixedly connected to the corresponding first connecting member 12 by a fastener; a second connecting member 61 located on the rear side wall 6c is detachably fixedly connected to the corresponding first connecting member 12 by a fastener; a second connecting member 61 located on the left side wall 6d is detachably fixedly connected to one of the corresponding two first connecting members 12 by a fastener, and is detachably fixedly connected to the other by snapping; a second connecting member 61 located on the right side wall 6e is detachably fixedly connected to one of the corresponding two first connecting members 12 by a fastener, and is detachably fixedly connected to the other by snapping.
[0066] In other embodiments, all the second connecting members 61 may be detachably fixedly connected to the first connecting member 12 by fasteners, or all the second connecting members 61 may be detachably fixedly connected to the first connecting member 12 by snap-fitting, as long as a detachable fixed connection between the first connecting member 12 and the second connecting member 61 can be achieved.
[0067] It is understandable that the number and layout of the first connecting members 12 and the second connecting members 61 are not limited to the above examples, and can be adaptively designed according to needs, which will not be explained one by one here.
[0068] The above shows and describes the basic principles, main features and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the scope of protection of this application.
