BRIEF DESCRIPTION OF THE DRAWINGS

These and other aspects and advantages of embodiments of the present invention will become apparent and more readily appreciated from the following descriptions made with reference to the accompanying drawings, in which:

Fig.l is a schematic view of a frequency conversion and dual-core steam mop according to an embodiment of the present invention;

Fig.2 is a cross- sectional view of frequency conversion and dual-core steam mop according to another embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENT (S)

Reference will be made in detail to embodiments of the present invention. The embodiments described herein with reference to drawings are explanatory, illustrative, and used to generally understand objects, characters and effects of the present invention. The embodiments shall not be construed to limit the present invention. The same or similar elements and the elements having same or similar functions are denoted by like reference numerals throughout the descriptions.

As shown in Fig.l, a frequency conversion and dual-core steam mop according to embodiments of the present invention comprises: a steam nozzle 1, a water tank 2, a gasifying assembly 3, a controller 4 and a water pump 5.

A water inlet 501 of the water pump 5 is communicated with a water outlet 201 of the water tank 2, and the controller 4 is electrically connected to the water pump 5 for controlling the operation of the water pump 5.

The gasifying assembly 3 comprises a first chamber 6, a second chamber 7 and a heating element 8. More practically, an inlet 602 of the first chamber 6 is communicated with an outlet 502 of the water pump5, and an outlet 601 of the first chamber 6 is communicated with an inlet 701 of the second chamber 7, for example, via a bent silicone tube 113. The steam nozzle 1 is communicated with an outlet 702 of the second chamber 7. The heating element 8 is used to heat the water contained in the first chamber 6 and second chamber 7.

As indicated by arrows shown in Fig.l, the water in the water tank 2 is pumped into the first chamber 6 by the water pump 5, then heated to gasify by the heating element 8. The generated steam is transmitted via the silicone tube 113 into the second chamber 7, and the steam is heated and gasified in the second chamber again. Finally, the steam in the second chamber 7 is ejected from the steam nozzle 1.

The water pump 5 may pump a desired and accurate amount of the water into the first chamber 6 from the water tank 2 under a control of the controller 4, then the generated steam is heated and gasified again in the second chamber 7, so that the steam may have a higher temperature. The steam in the second chamber 7 is ejected from the steam nozzle 1, thus improving the cleaning effect.

In some embodiments, the controller 4 may comprise a printed circuit board, i.e. PCB, and a controlling chip disposed on the PCB.

The water pump 5 may be a solenoid pump which does not have rotation components, thus the water pump 5 has a plurality of advantages, for example, the water pump 5 is simple in structure, excellent in sealing performance and reliable in operation. Moreover, the solenoid pump is controlled by the controlling chip, so that the water amount supplied to the gasifying assembly from the water tank 2 can be controlled accurately.

Fig. 2 shows another embodiment of the steam mop. The stem mop comprises a body 110 and a head 101. The steam nozzle 1 is disposed in the head 101, A duster cloth such as a towel may be disposed on a working side of the head 101, so that the steam nozzle 1 may be disposed towards to the towel.

The water tank 2 is disposed at a top of a rear end of the body 110 and may be integral with the body. A handle ( not shown ) may be mounted on the body 110, and the water tank 2 has a cover 201 disposed thereon for closing or opening the inlet of the water tank 2.

The water pump 5, gasifying assembly 3 and controller 4 are disposed in the body 110, so as to form the steam mop. Silicone tubes 103 may be connected between the water tank 2 and water pump5, between the water pump 5 and the first chamber 6, and between the second chamber 7 and the steam nozzle 1 respectively. In addition, the first chamber 6 and the second chamber 7 are communicated by the bent silicone tube 113.

The second chamber 7 may be formed in the first chamber 6, more specially, the second chamber 7 may be formed in the heating element 8 which is disposed in the first chamber 6. The first chamber 6 and second chamber 7 share the same heating element, so that the dimension of the steam mop is reduced and the cost of the steam mop is decreased.

The second chamber 7 is formed by a U-shaped tube, in other words, the interior chamber of the tube forms the second chamber 7, so that a length of the water passage of the second chamber 7 is prolonged and the heating time of the water in the second chamber 7 is increased, so that the cleaning performance of the steam mop is enhanced.

The outlet 601 of the first chamber 6 may be formed in a top of the first chamber 6 so as to prevent water from entering the first chamber 6 via the outlet 601, thus ensuring the water distributed around the heating element 8, and thereby improving the gasifying performance. The outlet 601 is communicated with the second chamber 7 via the bent silicone tube 113, and the second chamber 7 may be formed by an inverted U- shape tube extending inside the heating element 8, thus improving the gasifying performance and ensuring that no liquid water ejected out of the steam nozzle 1. Moreover, the configuration of the second chamber 7 can fully use the heat of the heating element 8, so that the liquid water contained in the steam can be further gasified.
