The upper shell assembly comprises a decoration part and an upper shell, the upper shell is provided with an air outlet, the decoration part is connected to the upper shell, and the air outlet is located in the orthographic projection of the decoration part on the upper shell so that the air outlet is located in a protection space formed by the decoration part and the upper shell. From this, the decoration plays certain guard action to the air outlet, avoids foreign matters such as dust, sewage to fall into the epitheca via the air outlet in, avoids blockking up the air outlet, does benefit to cleaning device's operation simultaneously to do benefit to and promote cleaning device's life-span.

An embodiment of the utility model provides a epitheca subassembly. Fig. 1 is a schematic view of a top case assembly according to an embodiment of the present invention; fig. 2 is an exploded view of the upper housing assembly shown in fig. 1. FIG. 3A is a cross-sectional view of the upper housing assembly shown in FIG. 1 taken along section line AB; fig. 3B is a right side view of the upper housing assembly shown in fig. 1. Fig. 4 is a structural view of the upper housing assembly shown in fig. 1 in a bottom view.

As shown in fig. 1, 2 and 3A, the upper case assembly 900 includes a decoration 36 and an upper case 30, the upper case 30 is provided with an air outlet 910, the decoration 36 is connected to the upper case 30, and the air outlet 910 is located in a front projection of the decoration 36 on the upper case 30 so that the air outlet 910 is located in a protection space 960 formed by the decoration 36 and the upper case 30. As shown in fig. 3A, a protection space 960 is formed by the decoration 36 and the upper case 30 to protect the air outlet from being blocked. From this, the decoration plays certain guard action to the air outlet, avoids foreign matters such as dust, sewage to fall into the epitheca via the air outlet in, avoids blockking up the air outlet, does benefit to cleaning device's operation simultaneously to do benefit to and promote cleaning device's life-span.

In some examples, as shown in fig. 2 and 4, the upper case 30 has a protruding structure 901 protruding toward the garnish 36, the protruding structure 901 forms a cavity 903 on a side away from the garnish, the air outlet 910 is provided in a side wall 903a of the protruding structure 901 forming the cavity 903, and the garnish 36 and the upper case 30 cooperate to form an air outlet space 902 such that the air outlet 910 is not blocked in the air outlet direction X of the air outlet 910. Therefore, the air outlet is arranged in the air outlet space 902, so that the air outlet can be protected by the decorating part, and foreign matters such as dust, sewage and the like are prevented from falling into the upper shell through the air outlet; and the air outlet direction X of the air outlet is not shielded, so that the air outlet effect is not influenced. As shown in fig. 2, the outlet space 902 is a region where the wind from the outlet passes.

In some examples, as shown in fig. 3B, within the air outlet space 902 formed by the decoration 36 and the upper case 30, in a right view, the upper case assembly 900 is located outside the air outlet 910, that is, the decoration 36 and the upper case 30 are both disposed to avoid the air outlet direction to form the air outlet space 902, and thus, the air outlet direction or the air outlet position of the air outlet 910 is not blocked by the structure of the upper case assembly 900.

For example, the shape of the air outlet may be a circle, a square, a trapezoid, or a sector, and of course, the embodiments of the present invention include but are not limited thereto, and the shape of the air outlet may also be other shapes.

For example, the quantity of air outlet can be one or more, of course, the embodiment of the present invention does not limit the quantity of air outlet.

For example, as shown in fig. 1 and fig. 2, the protruding structure 901 is located in an orthographic projection of the decoration 36 on the upper case 30, the decoration 36 protrudes out of the air outlet 910 in the air outlet direction of the air outlet 910 to protect the air outlet, and a notch 905 is provided at a side where the air outlet is provided to avoid the air outlet direction of the air outlet. As shown in fig. 1 and fig. 2, the decoration 36 is provided with a notch 905 in the air outlet direction X of the air outlet 910, so as to better avoid the air outlet direction of the air outlet.

In the negative pressure mechanism working process, the air current is discharged through the air outlet behind the negative pressure mechanism, because of the air-out direction of air outlet in the air-out space is not sheltered from, the air-out effect is not influenced, and in the direction of casing, the air outlet is protected by the decoration, avoids foreign matters such as dust, sewage to fall into cleaning device via the air outlet to avoid blockking up the air outlet, also can not influence the operation of negative pressure mechanism simultaneously.

The cleaning device can be suitable for surface cleaning under various conditions. For example, for cleaning on a horizontal surface, the negative pressure assembly can increase the pressure between the cleaning device and the horizontal surface, increase the friction force and improve the cleaning effect. The negative pressure component can be adsorbed on the non-horizontal surface for cleaning the non-horizontal surface.

For example, as shown in fig. 4 and 13, a portion of the hood 22 may be disposed in the cavity 903, and the air guide passage 262a of the hood 22 is sealingly connected to the outlet 910 in the cavity 903.

In some examples, the cleaning device is a window wiping robot and the surface to be cleaned includes a window or a wall surface. 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.
