The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.

In the present invention, if there is no explanation to the contrary, the orientation words used such as "up, down, top, bottom" usually refer to the direction shown in the drawings or refer to the vertical, vertical or gravity direction. The terms used to describe the mutual positional relationship of the components mentioned above. Among them, "front" and "rear" are relative to the user's perspective, the side close to the user is "front", and the side far from the user is "rear".

Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

The invention provides a new type of steam box, the water storage box of the steam box can greatly reduce the friction resistance and wear between the internal components of the steam box when the water is exchanged, and has low working noise. As shown in Figures 1 to 5, the steam box includes a box body with a water storage box installation chamber 100 therein, and a water box installation port 2 connected to the water storage box installation chamber 100 is provided on the front panel 1 of the box body; The water storage box 3 is built in the water storage box installation room 100 and can be drawn forward from the water storage box installation opening 2; the control panel 4 is arranged on the front side of the box front panel 1 and closes the water storage box installation opening 2; rolling The sliding mechanism is arranged in the water storage box installation chamber 100 to drive the control panel 4 to open forward or close the water storage box installation opening 2 backward.

In order to ensure the appearance integrity of the control panel 4 and the convenience of the user to take and place the water storage box 3, the water storage box 3 of the steam box is arranged behind the control panel 4, so the steam box needs to be provided with a pushing mechanism to move the position of the control panel 4 Thus, the water storage tank 3 can be taken out of the steamer. As shown in Figures 1 to 5, a water storage box installation port 2 is provided on the front panel 1 of the steam box, and a control panel 4 is provided on the front side of the front panel 1 of the box. The sliding mechanism drives the control panel 4 to open forward or close the water storage box installation opening 2 backward. The pushing mechanism of the present invention adopts a rolling pushing mechanism. The rolling elements of the rolling pushing mechanism and the internal components are in a rolling fit, so that the friction resistance between the elements is small, the working noise and the wear are also small, and it is avoided in the use process. Give consumers a bad user experience.

Optionally, the rolling pushing mechanism includes a fixed guide rail 5 and a pushing transmission arm 6. The pushing transmission arm 6 includes a panel connection section 61 and a rolling connection section 62 that are sequentially connected back and forth, and the fixed guide rail 5 includes a rail horizontal section 51 extending in a horizontal direction. And a rail ramp section 52 extending obliquely upward from the front end of the rail horizontal section 51; wherein the rolling connection section 62 forms a rolling connection with the fixed rail 5, and the front end of the panel connection section 61 is connected to the rear surface of the control panel 4 on.

In an alternative specific embodiment, as shown in Figures 2-9, the water storage box installation chamber 100 is provided on the upper part of the box, and the fixed guide rails 5 can be provided on the left and right sides of the water storage box installation chamber 100. It also includes a rail horizontal section 51 and a rail ramp 52. The horizontal section 51 of the guide rail is arranged along the front and rear direction of the horizontal plane, and the inclined ascending section 52 of the guide rail is connected to the horizontal section 51 of the guide rail for transition and the front end extends diagonally upward. The push transmission arm 6 includes a panel connection section 61 and a rolling connection section 62 that are sequentially connected back and forth. The front end of the panel connection section 61 is connected to the rear surface of the control panel 4, and the rolling connection section 62 and the fixed guide rail 5 form a rolling fit connection. .

Thus, the control panel 4 moves along the track of the fixed guide rail 5 under the drive of the sliding drive arm 6. When the control panel 4 is opened forward, the control panel 4 extends horizontally forward along the track of the horizontal section 51 of the guide rail and then moves along The track of the inclined ascending section 52 of the guide rail protrudes forward obliquely in the upward direction. When the control panel 4 extends forward to the extreme position, the position of the control panel 4 at this time is the extended position, and the control panel 4 is in an open state, and the user can pick and place the water tank 3 in the water tank installation port 2 operating. When the control panel 4 needs to be reset, the control panel 4 is retracted obliquely downward along the track of the ramp section 52 of the guide rail and then retracts horizontally and backward along the track of the horizontal section 51 of the guide rail. When the control panel 4 is retracted to the extreme position rearward, the position of the control panel 3 is at the retracted position, the control panel 4 is in a closed state, and the water storage box installation port 2 is sealed and blocked.

Due to the inclination of the ramp section 52 of the guide rail, if a pin movable fit is adopted between the driving arm 6 and the fixed guide rail 5, a larger friction force in the tangential direction will be generated between the pin and the ramp section 52 of the guide rail, increasing the pin rise The resistance and working noise will greatly affect the smoothness of the sliding mechanism. The rolling type pushing mechanism of the present invention forms a rolling fit connection between the pushing transmission arm 6 and the fixed guide rail 5, which can effectively reduce the friction between the pushing transmission arm 6 and the fixed guide rail 5, so that the sliding of the pushing transmission arm 6 is smooth. It lifts and greatly reduces the lifting resistance and working noise of the pushing transmission arm 6.

Those skilled in the art can understand that the water storage box installation chamber 100 can be arranged in the upper part of the steam box, but the present invention is not limited to this, and can also be arranged in the lower part of the steam box. When the water storage box installation chamber 100 is arranged in the lower part of the box body of the steam box, the fixed guide rail 5 includes a guide rail horizontal section 51 extending in the horizontal direction and a guide rail inclined section extending obliquely downward from the front end of the guide rail horizontal section 51 ( Not shown in the figure).

As shown in FIGS. 8 to 10, the vertical baffle 53 limits the fixed rail 5 to two parts: an inner rail and an outer rail. The rolling shaft assembly 7 includes an inner rolling element 71, a link fixing shaft 73 and a non-slip nut 74. The link fixed shaft 73 sequentially penetrates the rotation center hole of the outer rolling element 72, the fixed guide rail 5, the rotation center hole of the inner rolling element 71, the rolling shaft connecting hole 621 of the rolling connection section 62, and the anti-skid nut 74. The rolling type pushing mechanism is provided with double guide rails and double rolling elements to make the transmission of the pushing transmission arm 6 more stable and reliable. It should be noted that the side close to the center of the steam box is "inner", and the side far from the center of the steam box is "outer".

Furthermore, both the inner rolling element 71 and the outer rolling element 72 can be rolling bearings, thereby further reducing the friction resistance of the rolling-type pushing mechanism, and the rolling bearing has a compact structure, higher precision, and more stable and reliable.
