[0021] Refer to Figure 1 shown. It is the steam valve assembly provided by the present application. The steam valve assembly 100 is assembled at the steam outlet of the instant - heating steam boiler 200 for converting water into steam. By operating the steam valve assembly 100, the user can release the steam from the steam boiler 200 or enclose the steam in the steam boiler 200. Figure 1 In the embodiment shown, a steam nozzle 300 is arranged at the steam outlet of the steam valve assembly 100. The steam released via the steam valve assembly 100 can be applied to the outside from the steam nozzle 300.

[0022] The steam valve assembly 100 of the present application can be used in, for example, a steam cleaning device that uses a steam medium to clean a surface. In this steam cleaning device, a steam boiler for converting water into steam is configured, and the steam boiler has a steam outlet, and the steam valve assembly is installed at the steam outlet of the steam boiler.

[0023] Refer to Figure 2 and Figure 3 , the steam valve assembly 100 includes a valve body 2, a valve core 3, a release button 4, a spring 5, several sealing rings, a release - button fixing seat 8, and an air - outlet nozzle 9. The steam valve assembly 100 is an integral assembly, and it can be fixedly and sealingly assembled at the steam outlet of the steam boiler 200. The valve body 2, a part of the release - button fixing seat 8, and a part of the air - outlet nozzle 9 will be sealingly installed together with the housing of the steam boiler 200. A sealing ring 71 is arranged between a part of the housing of the steam boiler 200 and the valve body 2. The steam valve assembly 100 can be engaged with the steam outlet of the steam boiler.

[0024] The valve body 2 is a hollow structure, which is usually made of a material that is resistant to high temperatures and not easily deformed, such as a metal material. The valve body 2 extends in the direction of the axis X and has a first open end 21 and a second open end 22 along the axial direction. The valve body 2 has an inner wall surface 201 and an outer wall surface 202. The inner wall surface 201 of the valve body 2 defines a steam passage 23 extending along the direction of the axis X. The valve body 2 is provided with a steam inlet 24 that penetrates the inner wall surface 201 and the outer wall surface 202. The steam inlet 24 is used to introduce steam into the steam passage 23 along an inflow direction Y that intersects the direction of the axis X. A steam outlet 25 is provided at the second open end 22 of the valve body 2 for leading the steam out of the steam passage 23 along the outflow direction of the axis direction X. In the embodiment shown in the drawings of the present application, the inflow direction Y of the steam entering the steam passage 23 is perpendicular to the direction of the axis X.

[0025] The valve core 3 is arranged inside the valve body 2 in a manner that it can slide between an open position and a closed position along the axis X direction. In the embodiment shown in the drawings of the present application, the valve core 3 is located in the steam passage 23 inside the valve body 2, and the steam outlet 25 is located in the moving direction of the valve core 3. Figure 2 , 3 As shown, when the valve core 3 is in the open position, steam is allowed to flow from the steam inlet 24 to the steam outlet 25; Figure 4 As shown, when the valve core 3 is in the closed position, steam is blocked from flowing from the steam inlet 24 to the steam outlet 25 .

[0026] A sealing ring 72 is provided in the steam passage 23 of the valve body 2, and the sealing ring 72 is specifically located between the valve core 3 and the inner wall surface 201 of the valve body 2. Figure 2 , 3 As shown, when the valve core 3 is in the open position, the sealing ring 72 contacts the inner wall surface 201 of the valve body 2 and a component of the valve core 3; Figure 4 As shown, when the valve core 3 is in the closed position, the sealing ring 72 contacts the inner wall surface 201 of the valve body 2 and the valve core 3 at the same time. In the embodiment shown in the drawings of the present application, the sealing ring 72 is supported on the valve core 3 and can move with the valve core 3; in order to support the sealing ring 72, an annular groove 31 is provided on the valve core 3, and the sealing ring 72 is accommodated in the groove 31; the sealing ring 72 has a portion protruding radially outward to abut against the inner wall surface 201 of the valve body 2 when the valve core 3 is in the closed position. In order to cooperate with the sealing effect of the sealing ring 72, the corresponding position of the inner wall surface 201 of the valve body 2 is set to an inclined surface 2011, which can better achieve sealing contact with the sealing ring 72.

[0027] One end of the release button 4 extends into the interior of the valve body 2 through the first open end 21 to form a transmission relationship with the valve core 3. A part of the release button 4 is located outside the valve body 2. The release button 4 is configured for a user to apply an external force that slides the valve core 3 from the closed position to the open position. In the embodiment shown in the attached drawings of the present application, the valve core 3 and the release button 4 are formed as an integral member, which is in the shape of an elongated rod and is made of a material that is resistant to high temperatures and not easily deformed, such as a metal material.

[0028] The release button fixing seat 8 is fixedly installed at the first open end 21 of the valve body 2 and abuts against a part of the housing of the steam boiler 200. The release button 4 is slidably supported on the release button fixing seat 8 along the axis X direction. The release button fixing seat 8 can be composed of a plastic part. A sealing ring 73 is arranged between the release button fixing seat 8 and the first open end 21 of the valve body 2. A sealing ring 74 is arranged between the release button 4 and the release button fixing seat 8. The sealing ring 74 is supported on the release button 4. In order to support the sealing ring 74, a circular groove 41 is provided on the release button 4, and the sealing ring 74 is received in the groove 411; a part of the sealing ring 74 protrudes radially outward to contact the release button fixing seat 8.

[0029] The air outlet nozzle 9 is fixedly arranged at the second open end 22 of the valve body 2 and abuts against a part of the housing of the steam boiler 200. The air outlet nozzle 9 is in fluid communication with the steam outlet 25. The air outlet nozzle 9 can also be composed of a plastic part. The air outlet nozzle 9 can be arranged to be dockable with a steam pipe (not shown in the figure). A sealing ring 75 is arranged between the air outlet nozzle 9 and the second open end 22 of the valve body 2.

[0030] The spring 5 is configured to cause the valve core 3 to reset from the open position to the closed position when the external force from the release button 4 is lost. In the embodiment shown in the attached drawings of the present application, the spring 5 is arranged between the valve core 3 and the air outlet nozzle 9. One end of the valve core 3 facing the air outlet nozzle 9 forms a spring seat 32, and the spring 5 is installed on the spring seat 32.

[0031] As Figure 2 、 3 shown, when no force is applied to the release button 4 by the user, under the elastic force of the spring 5, the valve core 3 will remain in the closed position, the sealing ring 72 abuts against the inclined surface position of the inner wall surface 201 of the valve body 2, the steam passage 23 is cut off, and the steam is prevented from flowing from the steam inlet 24 to the steam outlet 25. As Figure 5 shown, when the user applies an axial force through the release button 4 to overcome the elastic force of the spring 5, the valve core 3 is moved to the open position, the sealing ring 72 leaves the inclined surface position of the inner wall surface 201 of the valve body 2, the steam passage 23 is opened, and the steam is allowed to flow from the steam inlet 24 to the steam outlet 25.

[0032] For the steam valve assembly of the present application, since the direction in which the valve core 3 moves from the closed position to the open position is along the axis X, which is also the steam outflow direction at the steam outlet; this arrangement will enable the user to drive the valve core 3 from the closed position to the open position with a relatively small applied force, which is labor-saving for the user to operate the steam valve assembly and provides a good user experience.

[0033] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements.
