Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a floor brush with an LED light source. Background Technology

[0002] Vacuum cleaners are highly efficient cleaning tools, primarily used for cleaning dust from floors, carpets, and other surfaces. With technological advancements, people's demands for vacuum cleaners have continuously increased. As a result, various floor brushes have been invented to work in conjunction with vacuum cleaners. Vacuum cleaners are no longer limited to sucking up dust, hair, and other dirt; they can also remove mites and their excrement, providing convenience for daily cleaning. However, the amount of dust, hair, mites, and their excrement that the human eye can observe is relatively limited. Therefore, green light is needed. The green light wavelength can create high-contrast shadows when dirt is present on the ground, allowing the human eye to clearly observe dust, hair, mites, and their excrement.

[0003] However, existing floor brushes on the market, such as the utility model patent with patent number "CN218922418U", entitled "Vacuum Cleaner Floor Brush and Vacuum Cleaner with Lighting Function", disclose a vacuum cleaner floor brush and vacuum cleaner with lighting function. The vacuum cleaner floor brush includes a floor brush body and an optical system disposed on the floor brush body. The optical system is used to illuminate debris located in the working area in front of the floor brush body. The optical system includes an LED light source that emits green light. Its optical system is located at the front of the floor brush body, so that slightly larger debris will be blocked by the optical system and cannot be sucked into the vacuum cleaner.

[0004] For the reasons mentioned above, it is necessary to improve the existing technology. Utility Model Content

A roller, which is rotatably mounted on the fixed wall; An optical system includes a green light lamp mounted on the fixed wall and a focusing lens mounted on the green light lamp. The focusing lens passes through the through hole and focuses the green light generated by the green light lamp to irradiate a cone-shaped irradiation area with a fixed angle from one side of the fixed wall.

[0007] In the above technical solution, the conical irradiation area includes a first edge and a second edge. The first edge is located outside the roller, and the second edge forms an angle α with the first edge, wherein the angle α is between 60° and 5°.

Detailed Implementation

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0020] Please see Figure 1-6 This utility model provides a floor brush with an LED light source, including a housing 1. An air intake 10 is provided on one side of the housing 1. One end of the housing 1 extends toward the opening of the air intake 10 to form a fixed wall 11. A through hole 12 is provided on the fixed wall 11 near the air intake 10. Roller 2, which is rotatably mounted on the fixed wall 11; Optical system 3, the optical system 3 includes a green light lamp 30 disposed on the fixed wall 11 and a focusing lens 31 sleeved on the green light lamp 30. The focusing lens 31 passes through the through hole 12. The focusing lens 31 focuses the green light generated by the green light lamp 30 and then irradiates a cone-shaped irradiation area 100 with a fixed angle from one side of the fixed wall 11.

[0021] In the above structure, the green light emits parallel green light. The human eye is more sensitive to green light of a fixed wavelength than to any other color of light of the same wavelength. At the same time, green light of a fixed wavelength range provides better visual illumination of micron-sized dust particles. The focusing lens is an optical element that is thicker in the center and thinner at the edges. It can refract the parallel green light emitted by the green light and focus it at its own focal point to form a high-energy light spot. The focusing lens can also be set with an adjustable optical path angle so that the green light emitted by this optical system forms a cone-shaped illumination area at a fixed angle in the working area at the front of the brush head, illuminating dirt and other contaminants that are invisible to the naked eye. The fixed wall can be formed by extending from either end of the housing. The green light is set in the fixed wall, and the focusing lens is fitted on it and protrudes through the through hole. This design allows the entire optical system to be integrated into the fixed wall without occupying the brush head's air intake and thus increasing the size of dust particles that the brush head can suck in.

[0022] Specifically, the conical irradiation area 100 includes a first edge 101 and a second edge 102. The first edge 101 is located outside the roller 2, and the second edge 102 forms an angle α with the first edge 101. The angle α is between 60° and 5°. Setting the conical irradiation area between 55° and 65° can control the irradiation area to prevent it from being too wide, resulting in insufficient brightness and failure to irradiate dust. It can also prevent the irradiation area from being too narrow, resulting in excessive brightness and the generation of glaring light spots.

[0023] Specifically, a side plate 13 is provided on the outer side of the fixed wall 11, and a limiting block 130 is protruding on the side plate 13. A limiting opening 110 is provided on the fixed wall 11 to cooperate with the limiting block 130. The limiting block on the side plate can cooperate with the limiting opening on the fixed wall multiple times, making it easy to install and disassemble multiple times without the need to use complicated tools to complete the installation and disassembly tasks.

[0024] Specifically, a connecting joint 4 is provided on one side of the housing 1. A suction pipe 40 communicating with the suction port 10 is provided in the inner cavity of the connecting joint 4. The connecting joint can connect the suction port of the housing and the vacuum cleaner through the suction pipe, thereby extending the length of the vacuum cleaner so that the vacuum cleaner can reach a position higher than the user's height.

[0025] Specifically, the green light 30 is an LED light with a parallel light effect close to that of a laser. LED lights can save power consumption, and the light emitted by the green light is close to the parallel light of a laser, which can magnify the shadows of dust on the ground many times more, increasing the amount of dust that people can observe.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
