[0002] Vacuum cleaners are common cleaning appliances in homes and offices. Currently, there are no vacuum cleaners on the market with ultraviolet sterilization function. The applicant is improving existing products to fill this gap, enabling vacuum cleaners to safely and efficiently sterilize floors with ultraviolet light. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a vacuum cleaner with ultraviolet sterilization function.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A vacuum cleaner with ultraviolet sterilization function includes a vacuum cleaner main unit and a floor brush connected to the vacuum cleaner main unit. The vacuum cleaner main unit is connected to the floor brush via a suction pipe. The floor brush includes a floor brush body, a roller brush arranged on the front side of the floor brush body, and an ultraviolet lamp module located behind the roller brush. The floor brush body also has a suction port located between the roller brush and the ultraviolet lamp module. The ultraviolet lamp module includes an ultraviolet lamp body and a triggering mechanism. The triggering mechanism includes a ground-contact roller, a movable bracket, and a safety switch. The movable bracket is inserted through the bottom wall of the floor brush body and a spring is sleeved on the movable bracket. The spring acts between the movable bracket and the floor brush body to make the movable bracket move up and down elastically. The ground-contact roller is connected to the bottom end of the movable bracket and can extend through the bottom wall of the floor brush body to contact the ground. The top of the movable bracket moves away from or close to the safety switch to trigger the safety switch to open or close, thereby controlling the start and stop of the ultraviolet lamp body.

[0006] A sleeve is formed on the bottom wall of the main body of the floor brush for the movable bracket to pass through. A channel is formed inside the sleeve for the movable bracket to move up and down. The bottom of the sleeve is open for the bottom end of the movable bracket to pass through. The spring acts between the movable bracket and the top wall of the channel.

[0007] The safety switch is arranged inside the brush body. The movable bracket includes a roller bracket for mounting the ground contact roller and a trigger bracket for triggering the safety switch. The roller bracket is located inside the sleeve and its top is provided with a connecting post that passes through the top wall of the sleeve and enters the brush body to connect with the trigger bracket.

[0008] The safety switch is arranged on the bottom wall of the brush body and located next to the sleeve. The trigger bracket has a horizontally extending trigger arm. When the movable bracket moves downward, the trigger arm presses against the switch of the safety switch to connect the safety switch and turn off the ultraviolet lamp. When the movable bracket moves upward, the trigger arm moves away from the switch of the safety switch to disconnect the safety switch and start the ultraviolet lamp.

[0009] The roller bracket is square in shape, and its bottom two sides extend downward to form lugs for rotating and mounting ground-contacting rollers; the inside of the sleeve is a square channel with a shape similar to that of the roller bracket.

[0010] The lugs on both sides of the ground-contacting roller are connected by a rotating shaft, and the rolling direction of the ground-contacting roller is consistent with the forward and backward direction of the floor brush.

[0011] The inner wall of the sleeve is provided with ribs along the channel direction, which abut against the side of the roller bracket.

[0012] The ultraviolet lamp body is long and narrow and is set perpendicular to the forward and backward direction of the ground brush.

[0013] The bottom wall of the floor brush body is provided with a groove for the ultraviolet lamp body to sink into.

[0014] A sealing ring is provided between the periphery of the ultraviolet lamp body and the bottom wall of the floor brush body.

[0015] The beneficial effects of this utility model are as follows: This utility model features an ultraviolet lamp module at the bottom of the floor brush body. The ultraviolet lamp module includes an ultraviolet lamp body and a triggering mechanism. When the user places the floor brush on the ground with a vacuum cleaner to begin work, the movable bracket of the triggering mechanism contacts the ground, retracts into the floor brush body, and triggers a safety switch to start the ultraviolet lamp body. When the user stops cleaning and lifts the vacuum cleaner, the movable bracket springs back to its original position under the action of a spring, triggering the safety switch again to stop the ultraviolet lamp body from working, thus preventing the ultraviolet light from irradiating the human body. The ultraviolet lamp body is located behind the roller brush and the suction port. After the ground in front has been cleaned by the roller brush and the suction port, the ultraviolet lamp body irradiates and sterilizes it, making the work highly efficient. Furthermore, the aforementioned triggering mechanism ensures safe use and poses no safety threat to the human body. Attached Figure Description

[0024] Reference Figure 1 A vacuum cleaner with ultraviolet sterilization function includes a vacuum cleaner host 1 and a floor brush 2 connected to the vacuum cleaner host 1. The vacuum cleaner host 1 is connected to the floor brush 2 through a vacuum tube 11.

[0025] like Figures 2 to 7 As shown, the floor brush 2 includes a floor brush body 21, a roller brush 3 arranged in front of the floor brush body 21, and an ultraviolet lamp module 4 located behind the roller brush 3. The floor brush body 21 is also provided with a dust suction port 22 located between the roller brush 3 and the ultraviolet lamp module 4.

[0026] The ultraviolet lamp module 4 includes an ultraviolet lamp body 41 and a triggering mechanism 42. The triggering mechanism 42 includes a ground-contact roller 421, a movable bracket 422, and a safety switch 423. The movable bracket 422 is connected to the bottom wall of the floor brush body 21, and a spring 424 is fitted on the movable bracket 422. The spring 424 acts between the movable bracket 422 and the floor brush body 21, causing the movable bracket 422 to move up and down elastically. The ground-contact roller 421 is connected to the bottom end of the movable bracket 422 and can pass through the bottom wall of the floor brush body 21 to contact the ground. The top of the movable bracket 422 moves away from or close to the safety switch 423, thereby triggering the safety switch 423 to open or close, thus controlling the start and stop of the ultraviolet lamp body 41.

[0027] When the user places the floor brush 2 on the ground with the vacuum cleaner to start working, the movable bracket 422 of the trigger mechanism 42 contacts the ground and retracts into the floor brush body 21, triggering the safety switch 423 to control the ultraviolet lamp 41 to start. When the user stops cleaning and lifts the vacuum cleaner, after the floor brush 2 leaves the ground, the movable bracket 422 pops out and resets under the action of the spring 424, triggering the safety switch 423 again to control the ultraviolet lamp 41 to stop working, so as to avoid the ultraviolet lamp 41 irradiating the human body. The ultraviolet lamp 41 is arranged behind the roller brush 3 and the suction port 22. After the ground in front is cleaned by the roller brush 3 and the suction port 22, the ultraviolet lamp 41 irradiates and sterilizes it. The work is very efficient, and the trigger mechanism 42 mentioned above also ensures the safety of use and will not pose a safety threat to the human body.

[0028] As a preferred embodiment of this utility model, a sleeve 211 is formed on the bottom wall of the brush body 21 for the movable support 422 to pass through. A channel for the movable support 422 to move up and down is formed inside the sleeve 211. The bottom of the sleeve 211 is open for the bottom end of the movable support 422 to pass through. A spring 424 acts between the movable support 422 and the top wall of the channel. Safety switch 423 is arranged inside the brush body 21. Movable bracket 422 includes roller bracket 4221 for mounting ground contact roller 421 and trigger bracket 4222 for triggering safety switch 423. Roller bracket 4221 is located inside sleeve 211 and its top is provided with connecting post 4223 that passes through the top wall of sleeve 211 and enters the interior of brush body 21 to connect to trigger bracket 4222. Specifically, safety switch 423 is arranged on the bottom wall of brush body 21 and next to sleeve 211. This arrangement makes the triggering mechanism 42 occupy less space and the interior of brush body 21 more compact. Trigger bracket 4222 has a horizontally extending trigger arm 4224. When movable bracket 422 moves downward, trigger arm 4224 presses against the switch of safety switch 423 to make safety switch 423 open and close ultraviolet lamp body 41. When movable bracket 422 moves upward, trigger arm 4224 moves away from the switch of safety switch 423 to make safety switch 423 open and start ultraviolet lamp body 41.

[0029] To ensure smooth movement of the movable support 422 within the sleeve 211, the roller support 4221 is square in shape. The interior of the sleeve 211 contains a square channel with a similar shape to the roller support 4221. The circumferential rotation of the roller support 4221 is restricted by the fit between the roller support 4221 and the inner wall of the sleeve 211, thus making the vertical movement of the movable support 422 more stable. Furthermore, the inner wall of the sleeve 211 has protruding ribs 2111 arranged along the channel direction, abutting against the side of the roller support 4221 to reduce friction between the side wall of the roller support 4221 and the inner wall of the sleeve 211, making the movement of the movable support 422 more sensitive. Lugs 4225 extend downwards from both sides of the bottom of the roller support 4221, rotatably mounting the ground contact roller 421. The two sides of the ground contact roller 421 are connected to the lugs 4225 via rotating shafts. The rolling direction of the ground contact roller 421 is consistent with the forward and backward direction of the floor brush 2.

[0030] Preferably, the UV lamp body 41 is elongated and positioned perpendicular to the forward and backward direction of the floor brush 2, allowing it to irradiate a large area of ​​the floor surface traversed by the floor brush 2. Furthermore, a groove 212 is provided on the bottom wall of the floor brush body 21 for the UV lamp body 41 to fit into, preventing it from protruding and thus avoiding interference with the movement of the floor brush 2. Since vacuum cleaners sometimes clean wet floors, a sealing ring is provided between the UV lamp body 41 and the bottom wall of the floor brush body 21 to prevent water from entering the floor brush body 21 and to prevent dust from entering.
