[0025] To describe the technical content, structural features, purposes and effects of the utility model in detail, the technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0026] Referring to Figure 1 , the technical solutions to be protected by the present application are described in detail taking the handle assembly 10 mounted on the upright scrubber 100 as an example.

[0027] The handle assembly 10 is mounted on the upper part of the machine body 20 of the upright scrubber 100. When operating the upright scrubber 100, the user can hold the handle assembly 10 with one hand and push the machine to move on the ground to be cleaned.

[0028] Referring to Figure 2 and Figure 8 , the handle assembly 10 includes a rod 1, a handle housing 2 and a button assembly 3. The handle housing 3 is fixed on the upper part of the rod 1, and the button assembly 3 is attached to the handle housing 2.

[0029] The rod 1 is of a hollow structure and is usually made of metal. The rod 2 can play a role in increasing the installation height of the handle housing 2 and transmitting the force acting on the handle housing 2 downward. Some components, such as wires, can pass through the inside of the rod 1.

[0030] As Figure 3As shown, the handle housing 2 is constructed to be suitable for one-handed gripping by a user. In this example, the handle housing 2 is assembled from a first housing component 21 and a second housing component 22. The first housing component 21 is fixedly connected to the upper part of the rod 2, and the second housing component 22 is mounted on the upper part of the first housing component 21. Together, they form a hollow housing structure. A button hole 221 is provided on the second housing component 22. The button assembly 3 includes an operation button 31, a circuit board 32, a light guide element 33, and a mounting base 34.

[0031] like Figure 5 As shown, the mounting base 34 has an upper surface 341 and a through hole 342 passing through the upper surface 341. An annular protrusion 343 surrounding the through hole 341 is provided on the upper surface 342 of the mounting base 34. Figure 6 As shown, the circuit board 32 is provided with light-emitting lamp beads 321; the light-emitting lamp beads 321 are usually LED lamp beads.

[0032] like Figure 7 As shown, the light guide element 33 includes a solid columnar light guide portion 331 located in the center and a mounting portion 332 surrounding the light guide portion 331; the light guide element 33 is supported on the upper part of the mounting base 34. The light guide element 33 is usually made of silicone material, but it can also be made of other elastic materials with good light transmission.

[0033] To achieve better light uniformity, the light guide 331 needs to have a certain thickness. Preferably, the thickness of the light guide 331 is more than 3mm, which can be set according to the overall thickness of the button.

[0034] like Figure 8 As shown, the operation button 31 has an inner surface 311 and an outer surface 312 that are opposite each other. The outer surface 312 has multiple light-transmitting areas 313 in the middle.

[0035] Combination Figure 9 As shown, the mounting base 34 is mounted on the inner wall of the first housing 21, the circuit board 32 is supported on the lower part of the mounting base 34, and the light-emitting beads 321 of the circuit board 32 face the through hole 342 so that the light emitted by the light-emitting beads 321 can pass through the through hole 341. The operation button 31 is exposed through the button hole 221 on the second housing component 21.

[0036] The lower part of the light guide element 33 is supported on the upper surface 342 of the mounting base 34. The light guide portion 331 faces the through hole 341. The mounting portion 332 is provided with a downward-facing groove 333. The annular protrusion 343 engages with the mounting portion 332 from the lower side of the light guide element 33, and the annular protrusion 343 is inserted into the groove 333.

[0037] The inner wall of the second shell part 22 is provided with a press-fit part 222. The press-fit part 222 is arranged around the button hole 221. The press-fit part 222 is press-fitted to the mounting part 332 from the upper side of the mounting part 332.

[0038] The operation button 31 is supported at the button hole 221 of the second shell part 22. The inner surface 311 is in contact with the upper surface 3311 of the light guide part 331. The outer surface 312 is exposed outside via the button hole 221. The light guide element 33 can guide the light emitted by the light-emitting lamp bead 321 to the light-transmitting areas 311. In this example, the outer surface 312 is pasted with a light-blocking film (not shown in the figure) at the area avoiding the light-transmitting areas 313.

[0039] In order to make the light amount emitted from the light-transmitting areas 311 sufficient, the upper surface 3311 of the light guide part 331 not only contacts the inner surface 311 of the operation button 31, but also the orthographic projection plane (the orthographic projection plane is the projection plane projected from the top to the bottom direction) of the light-transmitting areas 313 completely falls within the upper surface 3311 of the light guide part 331; that is, the upper surface 3311 of the light guide part 331 is not only vertically opposite to the light-transmitting areas 313, but also the area of the upper surface 3311 of the light guide part 331 is greater than or equal to the area of the light-transmitting areas 313. In this way, the light emitted by the light-emitting lamp bead 321 will be sufficiently guided to the light-transmitting areas 313 through the light guide part 331, so that the light display signal of the light-transmitting areas 313 can be easily observed.

[0040] In some embodiments, the wires (not shown in the figure) connecting the circuit board 32 can pass through the inside of the rod 1. In addition, in order to facilitate the user to further observe the light display signal of the light-transmitting areas 313, the outer surface 312 of the operation button 31 can also be pasted with a light-blocking film (not shown in the figure) at the area avoiding the light-transmitting areas 313; of course, the light-blocking film can also not be a pasting film, but be formed on the outer surface 312 of the operation button 31 by coating, printing or other processes.

[0041] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and the scope of protection of the present application is defined by the appended claims, the specification and their equivalents.
