Detailed Description

In order to describe the technical content, constructional features, objects and effects of the utility model in detail, the technical solutions of the embodiments of the utility model will be described in conjunction with the accompanying drawings in the embodiments of the utility model, and it is apparent that the described embodiments are only some embodiments of the utility model, not all embodiments of the utility model.

Referring to fig. 1, a handle assembly 10 mounted to a floor scrubber 100 is illustrated in detail to provide protection for the present application.

The handle assembly 10 is mounted to an upper portion of the main body 20 of the floor scrubber 100. The user can hold the handle assembly 10 in one hand and push the machine over the floor to be cleaned while maneuvering the floor-washing machine 100.

Referring to fig. 2 and 8, the handle assembly 10 includes a lever 1, a handle housing 2, and a button assembly 3. A handle housing 3 is fixed to an upper portion of the lever 1, and a button assembly 3 is attached to the handle housing 2.

The rod 1 is hollow and is usually made of metal. The lever 2 can function to raise the installation height of the handle housing 2 and transmit the force acting on the handle housing 2 downward. Some components, such as wires, etc., may pass through the interior of the rod 1.

As shown in fig. 3, the handle housing 2 is constructed in a structure suitable for one-hand grip by a user. In this example, the handle housing 2 is assembled from a first shell member 21 and a second shell member 22. The first housing part 21 is fixedly connected to the upper part of the rod 2, and the second housing part 22 is attached to the upper part of the first housing part 21, which together form a hollow housing structure. The second housing part 22 is provided with a button hole 221. The button assembly 3 includes an operation button 31, a circuit board 32, a light guide element 33, and a mount 34.

As shown in fig. 5, the mount 34 has an upper side surface 341 and has a through hole 342 passing through the upper side surface 341. An annular protrusion 343 surrounding the through hole 341 is provided on an upper side surface 342 of the mount 34. As shown in fig. 6, the circuit board 32 is provided with a light-emitting lamp bead 321, and the light-emitting lamp bead 321 is typically an LED lamp bead.

As shown in fig. 7, the light guide member 33 includes a solid columnar light guide portion 331 at the center and a mounting portion 332 surrounding the periphery of the light guide portion 331, and the light guide member 33 is supported at the upper portion of the mounting seat 34. The light guide element 33 is usually made of a silicone material, but may be made of other materials with better elasticity and light transmission.

In order to achieve a better light-equalizing effect, the light guide portion 331 needs to have a certain thickness, and preferably, the thickness of the light guide portion 331 is 3mm or more, and specifically may be set according to the entire thickness of the button.

As shown in fig. 8, the operation button 31 has an inner surface 311 and an outer surface 312 which are opposed up and down. The outer surface 312 has a plurality of light-transmitting regions 313 in the middle.

As shown in fig. 9, the mount 34 is attached to the inner wall of the first housing 21, the circuit board 32 is supported at the lower portion of the mount 34, and the light-emitting lamp beads 321 of the circuit board 32 face the through holes 342 so that the light emitted from the light-emitting lamp beads 321 can pass out of the through holes 341. The operation button 31 is exposed through a button hole 221 on the second case member 21.

The lower portion of the light guide member 33 is supported on the upper side surface 342 of the mount 34. The light guide 331 faces the through hole 341. The mounting portion 332 is provided with a recess 333 opening downward. The annular protrusion 343 is engaged with the mounting portion 332 from the lower side of the light guide member 33, and the annular protrusion 343 is inserted into the recess 333.

The second case member 22 is provided with a crimp 222 on an inner wall thereof. The crimping portion 222 is disposed around the button hole 221. The pressure-bonding section 222 presses the mounting section 332 from above the mounting section 332 of the light guide element 33.

The operation button 31 is supported at the button hole 221 of the second case member 22. The inner surface 311 is in contact with the upper surface 3311 of the light guide portion 331. The outer surface 312 is exposed to the outside via the button hole 221. The light guide element 33 can guide the light emitted from the light-emitting lamp beads 321 to the light-transmitting regions 311. In this example, the outer surface 312 is stuck with a light shielding film (not shown in the figure) at a region avoiding these light transmitting regions 313.

In order to make the amount of light emitted from these light transmitting areas 311 sufficient, the upper surface 3311 of the light guide portion 331 not only contacts the inner surface 311 of the operation button 31, but also the orthographic projection surface (orthographic projection surface is a projection surface projected in the top-down direction) of these light transmitting areas 313 falls entirely within the upper surface 3311 of the light guide portion 331, i.e., the upper surface 3311 of the light guide portion 331 is not only opposed to the light transmitting areas 313 up and down, but also the area of the upper surface 3311 of the light guide portion 331 is equal to or larger than the area of the light transmitting areas 313. So configured, the light emitted from the light-emitting lamp beads 321 is sufficiently introduced into the light-transmitting region 313 through the light-guiding portion 331, so that the light display signal of the light-transmitting region 313 can be easily observed.

In some embodiments, wires (not shown) connected to the circuit board 32 may pass through the interior of the rod 1. In addition, in order to facilitate the user to further observe the light display signals of the light-transmitting areas 313, the outer surface 312 of the operation button 31 may be further attached with light shielding films (not shown in the drawings) at areas avoiding the light-transmitting areas 313, and of course, the light shielding films may be formed on the outer surface 312 of the operation button 31 by a process such as coating, printing, or the like instead of the adhesive films.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the foregoing embodiments, which have been described in the foregoing embodiments and description merely illustrates the principles of the utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model, the scope of which is defined in the appended claims, specification and their equivalents.
