[0022] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended invention purpose, the present utility model is described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0023] It should be noted that the terms "first", "second", "third", "fourth", etc. in the description and claims of the present utility model are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0024] Please refer to Figures 1 to 4 , the multi-functional steam cleaner of the present utility model includes a main body assembly 1, a base assembly 2 and a multi-functional brush head 9. The main body assembly 1 and the multi-functional brush head 9 are detachably arranged on the base assembly 2. The main body assembly 1 includes a main housing 11, a steam generator 12, a first liquid storage device 3, a second liquid storage device 4, a first pipeline 5 and a second pipeline 6. The steam generator 12 is arranged in the main housing 11. The first liquid storage device 3 and the second liquid storage device 4 are detachably arranged on the main housing 11. One end of the first pipeline 5 is communicated with the first liquid storage device 3, and the other end of the first pipeline 5 is detachably communicated with the multi-functional brush head 9. One end of the second pipeline 6 is communicated with the second liquid storage device 4, and the other end of the second pipeline 6 is communicated with the multi-functional brush head 9. The first liquid storage device 3 can be configured to be communicated with the steam generator 12 and the multi-functional brush head 9, or be communicated with the steam generator 12 and the external environment. The second liquid storage device 4 can be configured to be communicated with the multi-functional brush head 9 and the external environment, or be communicated with the steam generator 12 and the multi-functional brush head 9.

[0025] Specifically, the first liquid storage device 3 in the present utility model is configured as a water tank, which is used to store the clear water that will be heated into steam. When the first liquid storage device 3 is configured to be communicated with the steam generator 12 and the multi-functional brush head 9, the first pipeline 5 is correspondingly configured to be communicated with the multi-functional brush head 9, and the steam is ejected through the multi-functional brush head 9, which can be used to perform cleaning functions or ironing functions. The flow direction of the liquid-gas mixture in the first liquid storage device 3 is: first liquid storage device 3 - steam generator 12 - first pipeline 5 - multi-functional brush head 9; when the first liquid storage device 3 is configured to be communicated with the steam generator 12 and the external environment, the multi-functional brush head 9 is correspondingly configured to be detached from the first pipeline 5, and the first pipeline 5 is directly communicated with the external environment, and the steam is ejected through the first pipeline 5, which can be used to perform humidification functions or other steam functions. The flow direction of the liquid-gas mixture in the first liquid storage device 3 is: first liquid storage device 3 - steam generator 12 - first pipeline 5 - external environment.

[0026] In particular, the second liquid storage device 4 in the present utility model can be configured as a clean water tank or a sewage tank. When the second liquid storage device 4 is configured as a sewage tank, the second liquid storage device 4 is configured to communicate with the multi-functional brush head 9 and the external environment, and is used to store the liquid-gas mixture sucked by the multi-functional brush head 9 when performing the cleaning function or the ironing function. The flow direction of the liquid-gas mixture in the second liquid storage device 4 is: multi-functional brush head 9 - second pipeline 6 - second liquid storage device 4 - external environment; when the second liquid storage device 4 is configured as a clean water tank, the second liquid storage device 4 is configured to communicate with the steam generator 12 and the multi-functional brush head 9, and together with the first liquid storage device 3, it stores the clean water that is about to be heated into steam. The flow direction of the liquid-gas mixture in the second liquid storage device 4 is: second liquid storage device 4 - steam generator 12 - second pipeline 6 - multi-functional brush head 9.

[0027] Understandably, when the second liquid storage device 4 is configured as a clean water tank or a sewage tank, the flow direction of the liquid-gas mixture inside it is opposite. Therefore, when switching, it is necessary to adjust the flow direction of the liquid-gas mixture in the second liquid storage device 4, and open or cut off the passage between the second liquid storage device 4 and the steam generator 12 and the external environment. However, during the process of switching the second liquid storage device 4 to a clean water tank or a sewage tank, it is not possible to simply adjust the flow direction of the liquid-gas mixture in the second liquid storage device 4, but the entire second liquid storage device 4 and the corresponding second pipeline 6 need to be replaced. This is because the second liquid storage device 4 and the second pipeline 6 used as the sewage tank will inevitably be dirty. If used as a clean water tank again, it will cause potential safety and hygiene hazards in the cleaning function, ironing function and humidifying function of the multi-functional steam cleaner, and even pollute the entire main machine assembly 1. Therefore, the second liquid storage device 4 of the present utility model should include several replaceable boxes, for example: a box 4a used as a sewage tank and a box 4b used as a clean water tank, rather than using the same box as a sewage tank and a clean water tank successively. The multi-functional steam cleaner of the present utility model realizes multiple functions in one machine through the detachable and replaceable first liquid storage device 3, second liquid storage device 4 and multi-functional brush head 9, provides multiple functions including cleaning function, ironing function, humidifying function, etc., greatly improves the usage frequency of the product, prevents asset idleness, and enhances the purchase desire of consumers. In addition, the main machine assembly 1, the base assembly 2 and the multi-functional brush head 9 in the present utility model can be freely separated and operated according to the actual needs of the working scenario, and the usage scenario is extremely wide and highly adaptable.

[0028] Further, the host component 1 includes a three-way device 7 and a switching device 8. The three-way device 7 is respectively connected to the first liquid storage device 3, the second liquid storage device 4, and the steam generator 12. The switching device 8 is used to switch the passage between the three-way device 7 and the second liquid storage device 4 between an open state and a closed state. Specifically, the passages between the three-way device 7 and the first liquid storage device 3 and between the three-way device 7 and the second liquid storage device 4 are both the input ends of the three-way device 7, while the passage between the three-way device 7 and the steam generator 12 is the output end of the three-way device 7. When the passage between the three-way device 7 and the second liquid storage device 4 is set to the open state by the switching device 8, the water in the first liquid storage device 3 and the second liquid storage device 4 flows into the steam generator 12 through the three-way device 7 and is heated to become steam, corresponding to the usage scenario where the second liquid storage device 4 is configured as a clean water tank; when the passage between the three-way device 7 and the second liquid storage device 4 is set to the closed state by the switching device 8, the water in the first liquid storage device 3 flows into the steam generator 12 through the three-way device 7 and is heated to become steam, and the second liquid storage device 4 is not connected to the three-way device 7, corresponding to the usage scenario where the second liquid storage device 4 is configured as a sewage tank. In this embodiment, the three-way device 7 is disposed below the main housing 11, the first liquid storage device 3, and the second liquid storage device 4. The switching device 8 is a silica gel sleeve. When the silica gel sleeve is inserted to block the passage between the three-way device 7 and the second liquid storage device 4, the switching device 8 sets the passage between the three-way device 7 and the second liquid storage device 4 to the closed state. When the silica gel sleeve is pulled out from the passage between the three-way device 7 and the second liquid storage device 4, the switching device 8 sets the passage between the three-way device 7 and the second liquid storage device 4 to the open state. In other embodiments of the present utility model, the switching device 8 can also be configured as an electric control switch or an electric control valve structure.

[0029] Please refer to Figure 5, Further, the second liquid storage device 4 includes a sewage passage 41, a clean water passage 42, an exhaust passage 43, and an exhaust baffle 44. One end of the sewage passage 41 is connected to the second pipeline 6, and the other end extends into the second liquid storage device 4 from the bottom end of the second liquid storage device 4. The clean water passage 42 is connected to the three-way device 7, and a switch device 8 is arranged on the clean water passage 42. The exhaust passage 43 is arranged above the sewage passage 41 and on the side wall of the second liquid storage device 4, and the exhaust baffle 44 is arranged between the sewage passage 41 and the exhaust passage 43. Specifically, the sewage passage 41 is a vertical pipeline with a height at least exceeding that of the second liquid storage device 4. Sewage and water vapor from the multi-functional brush head 9 will be ejected from the top end of the sewage passage 41, that is, the end of the sewage passage 41 located inside the second liquid storage device 4. The sewage falls into the second liquid storage device 4 under the action of gravity, while the water vapor collides with the exhaust baffle 44 extending downward from the top of the second liquid storage device 4 to achieve gas-liquid separation, and the water vapor is discharged to the external environment through the exhaust passage 43. The clean water passage 42 is a boss opening located at the bottom of the second liquid storage device 4. It is easy to understand that when the second liquid storage device 4 is configured as a sewage tank, the clean water passage 42 needs to be configured in a closed state by the switch device 8, or the clean water passage 42 and the switch device 8 are not directly provided; when the second liquid storage device 4 is configured as a clean water tank, the sewage passage 41 needs to be configured in a closed state, or the sewage passage 41, the exhaust passage 43, and the exhaust baffle 44 are not directly provided. If so configured, the battery life of the multi-functional steam cleaner is greatly improved, and the frequency of adding water is reduced.

[0030] Please refer to Figures 6 to 7 , Further, the multi-functional brush head 9 includes a brush head portion 91, a first brush head passage 92, and a second brush head passage 93 arranged inside the multi-functional brush head 9. One end of the first brush head passage 92 is connected to the first pipeline 5, and the other end of the first brush head passage 92 is located on the brush head portion 91 and is connected to the external environment. One end of the second brush head passage 93 is connected to the second pipeline 6, and the other end of the second brush head passage 93 is located on the brush head portion 91 and is connected to the external environment. Specifically, in this embodiment, the brush head portion 91 of the multi-functional brush head 9 is respectively provided with a clean water hole 911 for ejecting steam and a sewage hole 912 for recovering sewage. Two groups of clean water holes 911 are arranged at the upper and lower ends of the brush head portion 91, the sewage hole 912 is arranged between the two groups of clean water holes 911, the clean water hole 911 is connected to the first brush head passage 92, the sewage hole 912 is connected to the second brush head passage 93, and the first brush head passage 92 and the second brush head passage 93 are not connected to each other inside the multi-functional brush head 9.

The support portion 22 includes a plurality of support columns disposed below the base 21, and the support portion 22 is used to support the base 21, making the base 21 suspended relative to the ground. The shock-absorbing portion 23 includes a shock-absorbing pad disposed on the base 21, and the shock-absorbing portion 23 is clamped between the main housing 11 and the base 21. The positioning portion 24 includes a positioning hole opened on the base 21, and the main housing 11 can pass through the positioning portion 24 and be relatively fixed thereto, so that the main housing 11 is fixed on the base 21. The telescopic portion 25 includes a telescopic rod disposed on the base 21 in the height direction, and the clamping portion 26 is disposed at the top end of the telescopic portion 25 and is integrally fixed to the telescopic portion 25. The clamping portion 26 is used to clamp and fix the multi-functional brush head 9, and the multi-functional brush head 9 is thus fixed at any position in the height direction. Specifically, four circular positioning portions 24 are opened at the four corners of the base 21. A plurality of support portions 22 protrude beside the positioning portions 24 below the base 21. A shock-absorbing portion 23 protruding from the surface of the base 21 is disposed in the center of the base 21, which can reduce vibration and noise for the main housing 11. The telescopic portion 25 is a three-stage telescopic rod. A brush head baffle 28 for blocking sewage and steam is also disposed beside the clamping portion 26. The clamping portion 26 and the multi-functional brush head 9 are connected by quick insertion. The clamping portion 26 can also be used to clamp and fix the first pipeline 5. The main housing 11 together with the steam generator 12, the first liquid storage device 3, the second liquid storage device 4, etc. thereon or therein in the present utility model can be taken off the base assembly 2 together. The multi-functional brush head 9 can also be taken off the base assembly 2. The first liquid storage device 3 and the second liquid storage device 4 can be conveniently refilled with water and emptied. Therefore, the multi-functional steam cleaner in the present utility model can operate independently of the base assembly 2, be taken off and placed elsewhere according to actual working requirements, or be carried for use. When the present utility model needs to be stored or work at a fixed point, the main housing 11 can be relatively positioned with the base assembly 2 through the positioning portion 24 and safely and reliably contact the base assembly 2 through the shock-absorbing portion 23. The multi-functional brush head 9 can be fixed to the base assembly 2 through the clamping portion 26. The whole operation process is simple and clear, and each component is not easily damaged.
