[0035] As Figures 1-10As shown, a steam cleaner lance includes a shell 1, the shell 1 is divided into two parts, which are fixed by screws to form the whole steam cleaner, the steam cleaner lance is in the shape of a pistol. A steam pipe 3 is arranged in the shell 1, the steam pipe 3 is connected with external steam, a heat insulation pipe 2 is sleeved on the steam pipe 3, the size of the heat insulation pipe 2 is larger than that of the steam pipe 3, and part of the heat insulation pipe 2 extends to the outside of the shell 1, the heat insulation pipe 2 prevents the user from being scalded by touching the steam pipe 3. The steam pipe 3 is connected with a steam pipe 9, the bottom side of the steam pipe 9 is provided with a connecting pipe, the connecting pipe is connected with the steam pipe 3, two side plates 901 are arranged on the two sides of the steam pipe 9, the side plates 901 are provided with grooves, and the steam pipe 9 is internally provided with a steam outlet passage; a steam release valve 8 is movably connected with the steam pipe 9, the steam release valve 8 is arranged in the steam pipe 9, the steam release valve 8 is in the shape of T as a whole, the steam release valve 8 includes a valve body and a valve rod 802, the two sides of the valve body are provided with connecting blocks 801, the connecting blocks 801 are provided with tension springs 804, the other ends of the tension springs 804 are arranged on the side plates 901 of the steam pipe 9 and are clamped in the grooves of the side plates 901 to be fixed, the valve rod 802 is sleeved in the steam pipe 9 by the tension of the tension springs 804, the valve rod 802 is provided with a valve head 803, the valve head 803 is blocked in the steam outlet passage of the steam pipe 9 by the tension of the tension springs 804, and the valve rod 802 also blocks the connecting pipe of the steam pipe 9, so that the steam entering from the steam pipe 3 cannot enter the steam pipe 9. A steam release valve movable slot 102 is arranged on the shell 1, and the connecting blocks 801 of the steam release valve 8 are arranged in the steam release valve movable slot 102.

[0036] A tooth groove 101 is arranged on the inner side of the shell 1, a position lock 6 is arranged on the tooth groove 101, a circular baffle is arranged in the middle of the position lock 6, a convex point 602 is arranged at the front end of the baffle, a gear is arranged on the side of the baffle, a spring sleeving block is arranged on the other side of the baffle, and a position lock spring 601 is arranged around the spring sleeving block. The gear on the position lock 6 is engaged with the tooth groove 101 in the shell 1, so that the position lock 6 cannot rotate, and the convex point 602 on the position lock 6 extends out of the shell 1. Under normal circumstances, the position lock 6 is pushed by the elastic force of the position lock spring 601, at this time, the convex point 602 on the position lock 6 protrudes out of the shell 1, and the gear on the position lock 6 is also engaged with the tooth groove 101 in the shell 1.

[0037] A button 4 is arranged on the shell 1, the button 4 is movably connected with the shell 1 through a button rotating shaft 5, and the button 4 is rotated at a small angle counterclockwise around the button rotating shaft 5 as the center during movement. Teeth are arranged on the button 4, the teeth on the button 4 are in engagement with the gear on the position lock 6, an inner groove is arranged on the button 4, and the inner groove is in contact with the valve body of the steam release valve 8.

[0038] The limiting wheel 7 is arranged on the shell 1, the limiting wheel 7 is arranged with a rotating shaft to rotate the limiting wheel 7, the limiting wheel 7 is partially exposed outside the shell 1, a push piece is arranged on the exposed part of the limiting wheel 7, a limiting plate is arranged on the limiting wheel 7 inside the shell 1, the push piece on the limiting wheel 7 and the limiting plate are at the same horizontal position, the limiting plate on the limiting wheel 7 limits the rotation range of the button 4, therefore the steam cleaner gun is provided with three modes, which are initial state, small range and large range.

[0039] The lock catch 10 is further arranged on the shell 1, the lock catch 10 is arranged with a pressing spring, the pressing spring is arranged on the point on the steam pipe 9, the lock catch 10 can connect the sleeve of the external device to the head of the steam cleaner to change the air outlet passage of the steam.

[0040] The hand holding sliding groove is arranged on the shell 1, so that the user can hold more firmly, and the heat insulation layer is arranged on the hand holding area to prevent the hand holding area from heating and scalding the palm during use.

[0041] Working principle: in the initial state, the elastic force of the position lock spring 601 pushes out the position lock 6, the convex point 602 on the position lock 6 protrudes outside the shell 1, the gear on the position lock 6 is also engaged with the tooth groove 101 in the shell 1 to lock, the button 4 cannot be pressed, the steam valve 8 is blocked by the valve head 803 on the steam valve 8 due to the pulling force of the pulling spring 804, the steam outlet passage of the steam pipe 9 is blocked, the steam cannot enter, and the steam cleaner does not work to spray steam.

[0042] When it is needed to use, the convex point 602 on the shell 1 is pressed, at this time the tooth groove 101 on the shell 1 is separated from the gear on the position lock 6, at this time the position lock 6 can be rotated, the limiting wheel 7 is adjusted to the small range mode, the button 4 is pressed, the teeth on the button 4 rotate with the gear on the position lock 6, the button 4 rotates to clamp the valve body of the steam valve 8 into the inner recess on the button 4, the button 4 is pulled to pull out the valve rod 802 from the steam pipe 9, therefore the valve head 803 is away from the steam outlet passage, the steam enters from the steam pipe 3 through the connecting pipe at the bottom side of the steam pipe 9 to flow out from the steam outlet passage, the work is realized; because of the limiting of the limiting plate on the limiting wheel 7, the rotation angle of the button 4 cannot be rotated to the set position, the steam flow rate is small at present.

[0043] When the large range is needed, the push piece on the limiting wheel 7 is rotated, at this time the limiting plate on the limiting wheel 7 is rotated to the other side, there is no blockage of the limiting plate, at this time the steam valve 8 is pulled to the end stop of the steam valve movable groove 102, at this time the valve head 803 is farthest away from the steam outlet passage, and the steam flow rate reaches the maximum.

[0044] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, whatever the point of view. The scope of the present application is defined by the appended claims, and not by the above description, which is therefore intended to be merely illustrative and not restrictive. Any reference signs in the claims should not be considered as limiting the claims involved.

[0045] Furthermore, it should be understood that although the present specification is described in terms of embodiments, not every embodiment according to the present specification needs to exhibit each and every characteristic specified in the present specification. The specification can also be described in terms of a single independent technical solution, but this does not mean that each embodiment according to the present specification only contains one independent technical solution.
