[0032] like Figure 1 - Figure 7 As shown, the present invention provides an embodiment of a steam mopping device.

[0033] The steam mop device includes a handle 1 and a mop body 2 connected to the handle 1, the mop body 2 includes a shell and a dust bucket module 22 arranged on the shell for collecting cleaned objects, a fan module 25 connected to the dust bucket module 22 and generating a rotating airflow negative pressure in the dust bucket module 22, and a steam module for generating steam, and also includes a mop plate assembly 27 connected to the bottom of the shell in an up-and-down floating manner, and the mop plate assembly 27 is provided with a steam port connected to the steam module.

[0034] Specifically, the steam mop device includes a controller (not shown in the drawings) that controls the operation of the steam module and the fan module 25. The steam module and the fan module 25 are not the improved components of the invention, and can be implemented by using the existing technology. The specific implementation principle and specific structure of the steam module and the fan module 25 will not be described in detail. The handle 1 is used to control the moving direction of the mop body 2. The handle 1 is movably connected to the mop body 2, and its angle with the mop body 2 can be adjusted.

[0035] The housing includes an upper housing 21 and a lower housing 24 adapted to the upper housing 21. A steam module and a fan module 25 are arranged in a cavity formed between the upper housing 21 and the lower housing 24, as well as a dust bucket module 22 fixedly engaged with the housing. The dust bucket module 22 includes a dust bucket outer shell 220 provided with a strip-shaped air inlet 224, a filter cartridge 221 provided with a first air vent 2210 in the dust bucket outer shell 220, and an inner cylinder 223 provided with a second air vent 2230 in the filter cartridge 221. A dust bucket air outlet is provided on one side of the dust bucket module 22, which passes through the outer shell, the filter cartridge and the inner cylinder and is connected to the fan module.

[0036] A support portion 240 and a step are provided at the bottom of the lower shell 24. A floor mopping plate assembly 27 that can float up and down is provided at the bottom of the step. The floor mopping plate assembly 27 includes a floor mopping plate body 270 and a connector (not shown in the drawings) connecting the floor mopping plate body 270 and the bottom of the lower shell 24. A guide structure (not shown in the drawings) is provided between the floor mopping plate body 270 and the lower shell 24, and an elastic component 271 that keeps the floor mopping plate body 270 away from the lower shell 24. The guide structure can ensure that the floor mopping plate assembly 27 floats up and down more smoothly. The elastic component 271 includes a spring.

[0037] When in use, the floor mop assembly 27 is in contact with the ground, and the controller controls the steam module and the fan module 25 to work simultaneously or individually. When the ground is uneven, the floor mop assembly 27 connected up and down can move toward the lower shell 24 to adapt to the uneven ground, avoiding the phenomenon that the uneven ground area cannot be effectively cleaned, and improving the cleaning efficiency of the uneven ground.

[0038] The dust bucket module 22 includes a dust bucket shell 220 provided with a strip-shaped air inlet 224, a filter cartridge 221 provided with a first air hole 2210 in the dust bucket shell 220, and an inner cylinder 223 provided with a second air hole 2230 in the filter cartridge 221. A first annular gap A and a second annular gap B are respectively provided between the filter cartridge 221, the inner cylinder 223 and the dust bucket shell 220, and the strip-shaped air inlet 224 is connected to the first annular gap A through an arc-shaped air inlet channel C, that is, an isolation plate 222 is provided in the dust bucket shell 220, and the isolation plate 222 forms an arc-shaped air inlet channel C between the strip-shaped air inlet 224 and the dust bucket shell 220. The arc-shaped air inlet channel C extends from the strip-shaped air inlet 224 to the vicinity of the first air hole 2210 on the filter cartridge 221 and merges with the first annular gap A.

[0039] A dust bucket air outlet (not shown in the drawings) is provided on one side of the dust bucket module 22, which passes through the dust bucket shell 220, the filter cartridge 221 and the inner cylinder 223 and is connected to the fan module 25, that is, a dust bucket air outlet 2201 is provided on one side of the dust bucket shell 220, a filter cartridge air outlet 2211 is provided on the filter cartridge 221 at a position corresponding to the dust bucket air outlet 2201, and an inner cylinder air outlet 2231 is provided on the inner cylinder 223 at a position corresponding to the filter cartridge air outlet 2211. The first air vent 2210 and the second air vent 2230 are staggered, and the aperture of the first air vent 2210 is larger than that of the second air vent 2230.

[0040] When in use, there is a small gap between the strip-shaped air inlet 224 and the cleaning surface. Under the action of the fan module 25, the strip-shaped air inlet 224 creates a negative pressure inside the dust bin module 22, and the dirt near the strip-shaped air inlet 224 is sucked in. Due to the action of the arc-shaped air inlet duct C and the first annular gap A, the wind in the first annular gap A moves in a rotational manner, and enters the second annular gap B area through the first air hole 2210, and then is discharged from the dust bin module 22 from the second air hole 2230. The surface of the filter cartridge 221 is provided with a filter net, which can easily and evenly distribute larger dirt on the surface of the filter cartridge 221 and separate it from the dust, thereby avoiding blockage during the cleaning process.

[0041] As needed, the steam port 272 adopts a trumpet-shaped structure, so that when using steam to mop the floor to kill bacteria, the steam module can be controlled to generate steam through the steam port 272 to reach the cleaned floor, so that the steam can be sprayed over the maximum area.

[0042] In order to reduce the friction between the mop and the ground when mopping the floor and avoid scratching the surface of the cleaning place, a roller 29 is provided on the mop body. The roller 29 allows the support part 240 provided at the bottom of the lower shell 24 to maintain a certain gap with the cleaning surface.

[0043] In order to prevent the mop from being damaged when there are large objects in the cleaning area, a rotatable first elastic scraper 26 is provided on the dust bucket housing at the front end of the strip-shaped air inlet 224. The first elastic scraper 26 can push away large objects in the forward cleaning direction to prevent them from entering the dust bucket module 22. A rotatable second elastic scraper 28 is provided on the dust bucket housing at the rear end of the strip-shaped air inlet 224. The second elastic scraper 28 can push away large objects in the backward cleaning direction to prevent them from entering the dust bucket module 22. Each scraper strip is provided with a scraping portion and a lifting portion arranged on the outside of the scraping portion, that is, the first elastic scraper strip 26 is provided with a first scraping portion 262 and a first lifting portion 261 arranged on the outside of the first scraping portion 262; the second elastic scraper strip 28 is provided with a second scraping portion 282 and a second lifting portion 281 arranged on the outside of the second scraping portion 282. When sweeping forward, the second scraping portion 282 of the second elastic scraper strip 28 contacts the cleaning surface, such as the ground, and the first lifting portion 261 on the first elastic scraper strip 26 contacts the ground at this time, so that the first scraping portion 262 is separated from the cleaning surface, that is, a dust suction and cleaning gap is formed between the first scraping portion 262 and the cleaning surface for dust and the like to enter the strip-shaped air inlet suction port 224. When mopping the floor in the reverse direction, the first scraping part 262 of the first elastic scraping strip 26 forms a surface contact with the floor, and the second scraping part 282 of the second elastic scraping strip 28 is separated from the floor by the second lifting part 281, so as to form a certain gap, so that the dust on the floor is not blocked and affects the cleaning. At the same time, in cooperation with the first elastic scraping strip 26, a greater adsorption effect can be achieved, and the cleaning is better. In the use state, the cleaning gap between the scraping part and the cleaning surface is about 5MM.

[0044] The angle formed between the first scraping portion 262 and the first lifting portion 261 is between 15 and 60 degrees, preferably 30 or 45 degrees; the angle formed between the second scraping portion 282 and the second lifting portion 261 is between 15 and 60 degrees, preferably 30 or 45 degrees.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents, and these modifications or replacements may cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
