[0037] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the accompanying drawings to explain the present invention in detail. Figure 8 The open direction of the steam sweeping area 6 shown in FIG. 1 is the front direction of the present embodiment.

[0038] See also Figures 1 to 12 As shown in , the steam mop provided in this embodiment includes a mop head 1 and a handle 5 connected to each other, a steam module 4 arranged in the mop head 1 or on the handle 5 or separately arranged outside, and the lower end of the mop head 1 also has a plane for matching the mop cloth 2; wherein,

[0039] A rotating shaft assembly is movably mounted on the mop head 1, and the upper end of the rotating shaft assembly is connected to the handle 5, so that the handle 5 has at least a first movable state of flipping forward and backward relative to the mop head 1 and a second movable state of circumferential rotation relative to the mop head 1;

[0040] In addition, the mop head 1 is provided with a locking member for limiting the movement of the rotating shaft assembly, and causes the handle 5 to have a locking state in which its axis is kept parallel or perpendicular to the plane where the lower end surface of the mop head 1 is located, so that the steam mop can stand upright on the ground adjacent to the wall with the front end surface of the mop head 1 and one side of the handle 5 as fulcrums.

[0041] Based on the above technical solution, the steam mop includes a mop head 1, a handle 5, a steam module 4, and a rotating shaft assembly. The handle is movably connected to the mop head through the rotating shaft assembly and has an active state that can be flipped forward and backward and rotated circumferentially. The locking member has a locking state that is maintained parallel or perpendicular to the mop head, so that during the storage process, the rotating shaft assembly can be locked by the locking member and the steam mop can be uprightly leaned against the ground adjacent to the wall with the front end surface of the mop head and one side of the handle as fulcrums, thereby eliminating the need for an additional base as a storage support and avoiding the problem of easy tilting to the left or right after being placed upright against the wall.

[0042] In a preferred embodiment, specifically as Figures 2 to 7 As shown in the figure, the mop head 1 is provided with a shaft bracket 8, on which a first movable shaft 9 that can be flipped in the front-back direction is provided, and on which a second movable shaft 3 that can rotate circumferentially relative to the first movable shaft 9 is provided, and the second movable shaft 3 passes through the mop head 1 upward and is connected to the handle 5, and the first movable shaft 9, the second movable shaft 3, and the handle 5 are coaxial, and the first movable shaft 9 and the second movable shaft 3 together constitute a shaft assembly. Obviously, the shaft assembly can also be designed as a universal rotating structure, and is not limited thereto.

[0043] As a further preferred embodiment, the mop head 1 has an opening for passing the second movable shaft 3, and the upper end surface of the mop head 1 is surrounded by a semi-arc-shaped surrounding wall 106 with a rear end open, the locking member includes a plurality of limit grooves formed in the mop head 1 and on the semi-arc-shaped surrounding wall 106, and the first movable shaft 9 and the second movable shaft 3 have a plurality of limit blocks corresponding to the limit grooves, which are used to clamp and escape from the limit grooves through the limit blocks to cause the first movable shaft 9 and the second movable shaft 3 to have a first clamping state perpendicular to the mop head 1, a second clamping state parallel to the mop head 1, and a movable state movable with the mop head 1.

[0044] As a further preferred embodiment, a second limit block 902 and a first limit block 901 are respectively protruded on the front and rear side walls of the first movable rotating shaft 9, a third limit block 301 and a fourth limit block 302 are respectively protruded on the front and rear side walls of the second movable rotating shaft 3, and a first limit groove 101 is formed on the inner wall of the mop head 1 at the rear side position of the first movable rotating shaft 9, and a second limit groove 102 and a third limit groove 103 are respectively formed at the front and rear sides of the semi-arc surrounding wall 106, and the first limit groove 101, the second limit groove 102, and the third limit groove 103 together constitute a locking member, and when the first limit block When 901 is clamped on the first limiting groove 101 and the third limiting block 301 is clamped in the second limiting groove 102, the axes of the first movable shaft 9 and the second movable shaft 3 remain perpendicular to the plane where the mop head 1 is located; when the fourth limiting block 302 is clamped in the third limiting groove 103 and the second limiting block 902 is clamped in the second limiting groove 102, the axes of the first movable shaft 9 and the second movable shaft 3 remain parallel to the plane where the mop head 1 is located; in addition, in the situation between the two, that is, when they are not clamped to each other, the first movable shaft 9 and the second movable shaft 3 can be flipped and rotated at will to maintain a movable state.

[0045] Furthermore, in the first clamping state, the first movable shaft 9 and the second movable shaft 3 are both limited in the up, down, left, and right directions, so that the whole machine can stand stably. In the second clamping state, the first movable shaft 9 and the second movable shaft 3 are also limited in the up, down, left, and right directions, so that the whole machine can stand upright and lean against the wall with the handle 5 to stand stably. In the active state, the first movable shaft 9 and the second movable shaft 3 can move the handle 5 up and down (flip front and back) and left and right (rotate in the circumferential direction). Further, Figure 8 As shown in , the left and right sides of the third limiting groove 103 are further formed with guiding inclined surfaces 104 to guide the fourth limiting block 302 so that it can be accurately clamped in the third limiting groove 103 .

[0046] In a preferred embodiment, in combination Figures 8 to 12As shown in FIG. 1 , a detachable dust collecting seat 7 is provided at the lower end of the mop head 1, a mop 2 is provided at the bottom of the dust collecting seat 7, and a dust collecting chamber 703 for collecting dust is formed between the mop head 1 and the dust collecting seat 7, and a steam nozzle 10 of the steam module 4 is arranged in the mop head 1;

[0047] In addition, the dust storage seat 7 is formed with a steam sweeping area 6 which is open in the front direction and communicated with the dust collecting chamber 703. The steam spraying port of the steam spraying head 10 faces the steam sweeping area 6, so as to impact the solid waste on the ground in the steam sweeping area 6 with steam and cause the moving solid waste to be sprayed into the dust collecting chamber 703. Thus, the steam can be wetted on the ground for mopping and the functions of steam sweeping and collecting the moving solid waste can be realized at the same time.

[0048] In this embodiment, the middle front position of the dust holder 7 is recessed in the rearward direction to form a steam sweeping area 6, so that the dust holder 7 and the mop 2 are overall in a "concave" shape when viewed from a top view, so that the steam sweeping area 6 is blocked in the left and right directions and the rear direction but open in the front direction, and a dust collecting channel for allowing movable solid garbage to enter is formed between the dust holder 7 and the mop head 1 at the left and right sides of the steam sweeping area 6, and the steam outlet is located directly above the steam sweeping area 6 to spray steam and cause the movable solid garbage to enter the dust collecting chamber 703 through the dust collecting channel.

[0049] As a further preferred embodiment, the number of steam ejection ports is two, which are arranged in an interlaced manner, and the steam ejection directions of the two steam ejection ports are both inclined. Specifically, in the present embodiment, the steam ejection directions of the two steam ejection ports are mutually in an "eight" shape, so that the movable garbage on the ground in the steam sweeping area 6 is impacted by the steam and enters the dust collecting chamber 703 in the direction of the left and right sides, but it is obvious that the steam ejection direction of the two steam ejection ports can also be designed to be tilted in the same side direction to promote the movable garbage to be collected on the same side in the dust collecting chamber 703. At the same time, the number of steam ejection ports is at least one, and two are the preferred solutions of this implementation, and it is obvious that more can also be designed based on demand. In addition, the ejection direction of the steam ejection port can also be considered to be designed as a solution that is previously tilted backward, so that the movable solid garbage is impacted and rebounds and ejects to the rear position of the middle part of the dust collecting chamber 703, which can also achieve the above-mentioned technical purpose, but is not limited to this.

[0050] In a preferred embodiment, the upper end surface of the dust storage seat 7 is convexly formed around its outer contour to form a peripheral edge 704, and a plurality of buckle grooves 702 are provided on the outer side surface of the peripheral edge 704, and the inner side wall of the lower end of the mop head 1 is provided with convex ribs 105 of the same number and position as the buckle grooves 702, so as to detachably connect the mop head 1 and the dust storage seat 7, and a pedal 701 is provided at the rear side of the dust storage seat 7 to assist in the assembly and removal of the mop head 1 by stepping on the pedal 701. Further, the upper end surface of the dust storage seat 7 is convexly formed to form a baffle 705 in the rear direction of the steam sweeping area 6, so as to promote the movable garbage in the steam sweeping to enter the dust collecting chamber 703 only from the two dust collecting channels.

[0051] In a preferred embodiment, see Figure 2 , Figure 3 as well as Figure 4 As shown in , the first movable rotating shaft 9 and the second movable rotating shaft 3 are both hollow in the middle, and a steam channel 303 is formed in the second movable rotating shaft 3. The steam channel 303 passes downward through the first movable rotating shaft 9 and is connected to the steam spray head 10 via the steam pipeline 11. The steam module 4 includes a steam generator mounted on the handle 5, and the steam outlet of the steam generator is transported to the steam spray head 10 via the steam channel 303 and the steam pipeline 11. In this embodiment, since there are two steam spray outlets on the steam spray head 10, the steam pipeline 11 is designed as a three-way pipeline structure, the inlet of which is connected to the steam channel 303 and the two outlets are connected to the two steam spray heads 10 respectively. Furthermore, a cleaning liquid channel 304 is also provided in the second movable rotating shaft 3, and a plurality of cleaning liquid water holes 801 are longitudinally penetrated on the rotating shaft bracket 8 and the dust storage seat 7 directly below the cleaning liquid channel 304, so that the cleaning liquid can flow downward into the mop 2, and a cleaning liquid containing and conveying component is correspondingly designed on the handle 5, and the cleaning liquid is conveyed through the inside of the second movable rotating shaft 3.

[0052] As a further preferred embodiment, in a top view, the dust collecting seat 7 and the mop 2 are both in a "concave" shape with a notch on the front side, and two supports are erected side by side in the left and right directions on the rotating shaft bracket 8. The left and right sides of the first movable rotating shaft 9 have convex shafts respectively, and the upper ends of the supports have arc grooves for accommodating the convex shafts. In addition, the outer ring of the mop 2 has a curling edge 201, so that the mop 2 can be detachably connected to the lower end surface of the mop head 1. Fig.12 As shown in , the device also includes a cleaning brush 12 as an independent component for cleaning the mop 2. Figure 1 As shown in the figure, the a indicated is the solid waste inlet. Fig.10 The b indicated in the figure is the wall. Fig. 9 The indicated c is the active solid waste located in the steam sweeping area 6, and d is the steam impact direction, i.e., the active path of the solid waste. Fig.11 The "e" indicated in the figure is a foot.

[0053] The principle of steam sweeping in this scheme is: first, solid garbage is allowed to enter the steam sweeping area in the mop through the solid garbage inlet arranged at the front of the mop. Two steam nozzles 10 are arranged above the cavity in this area, one is responsible for the garbage on the left side of the cavity, and the other is responsible for the garbage on the right side of the cavity. Since the steam nozzle 10 is arranged obliquely, the steam ejected from the small hole of the nozzle will have a strong impact force, and the nozzle is close to the ground, so large particles of garbage can be blown into the dust collecting cavity.

[0054] This solution does not require the base in the existing solution: if the existing steam mop is directly against the wall, it will fall from the left and right sides, so the design requires the steam mop to be able to stand to prevent it, which gave birth to the base. One of the purposes of this solution is to design a structure that will not fall against the wall, and it only needs to control it from falling left and right when against the wall. However, the existing mop needs the handle to move up and down and left and right when cleaning. In this solution, the shaft is designed to be in two states: upright and lying flat. The shaft will be completely moved, and it can move freely in the state between upright and lying flat. Therefore, when upright, the whole machine is placed standing, and lying flat needs to be placed against the wall without a base, and the state between the two is the state when the user is using it.

[0055] A method of cleaning the mop without direct contact with your hands: clean the dust holder and the mop together, step on the pedal to separate the dust holder from the mop head, rinse the dust collection chamber on one side, and use a cleaning brush to remove particles and hair on the mop on the other side, and then brush the water off the mop.

[0056] Thereby, the steam is fully utilized, so that the device has both sweeping and mopping functions; and the problem that the mop is easy to tip over when placed against the wall is solved, and the base is eliminated; at the same time, the mop of the steam mop can be scrubbed to avoid the invasion of germs in the dirt to the skin; and compared with the traditional steam mop, the structural complexity and cost are not increased. The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive of the utility model. Those skilled in the art understand that many changes, modifications, and even equivalences can be made to it within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
