[0035] Embodiment

[0036] Combined with Figures 1 to 7 As shown, this embodiment provides a control device, which can be used for a switching valve with a flow regulation function, and includes a guide sleeve 1 for rotating to control the flow rate of the switching valve, a slider 2 movable relative to the guide sleeve, a button housing 3 movable relative to the guide sleeve, a spring 4 for applying a force to the slider 2 and the button housing 3, and a control member 5;

[0037] A trajectory guide groove 21 is provided on the slider 2, and an upper action point 22 and a lower action point 23 are provided on the trajectory guide groove 21; one end of the control member 5 is arranged on the guide sleeve 1, and the other end is movably arranged on the trajectory guide groove 21 and switches between the upper action point 22 and the lower action point 23 so that the slider 2 can open or close the switching valve;

[0038] The button housing 3 presses the slider 2 to move under an external force so that the control member 5 switches between the upper action point 22 and the lower action point 23; the button housing 3 rotates under an external force to drive the guide sleeve 1 to rotate, thereby realizing the adjustment of the flow rate of the switching valve.

[0039] Specifically, in this embodiment, as Figure 2 And Figure 5As shown, a track guiding groove 21 is provided on the side surface of the slider 2. The guiding sleeve 1 includes a first semi-circular guiding sleeve 11 and a second semi-circular guiding sleeve 12; a base body is provided at the bottom of the first semi-circular guiding sleeve 11; the second semi-circular guiding sleeve 121 is connected to the base body by bolts, and an installation cavity 14 is formed between the second semi-circular guiding sleeve 121 and the first semi-circular guiding sleeve 11. A guiding portion 15 is arranged in the installation cavity 14 along the axial direction; a guiding groove 24 adapted to the guiding portion 15 is provided on the side surface of the slider 2. An external tooth 13 is provided on the outer side surface of the base body, and an internal tooth 31 meshing with the external tooth 13 is provided on the inner side of the key housing 3; the external tooth 13 and the internal tooth 31 guide the key housing 3 to slide along the axis of the guiding sleeve 1. The arrangement of the first semi-circular guiding sleeve 11 and the second semi-circular guiding sleeve 12 of the guiding sleeve 1 facilitates the installation of the control member 5. Of course, in other embodiments, other acting points may be provided between the upper acting point 22 and the lower acting point 23 on the track guiding groove 21 to achieve stepped positioning heights with different pressing stroke distances.

[0040] In this embodiment, as Figure 7 shown, the control member 5 is in a Z shape; when the user presses the key housing 3, the spring is compressed, and the other end of the control member 5 moves upward along the track guiding groove 21 of the slider 2; when the hand is released, the control member 5 moves along the track to the upper acting point 22 on the track guiding groove 21 of the slider 2 to stop the slider 2. At this time, the spring is compressed and the switch valve is in a closed state; when the key housing 3 is pressed again by hand, the other end of the control member 5 first moves upward to the highest point along the track guiding groove 21, and then when the hand is released again, under the action of the spring force, the slider 2 is pushed upward, and the other end of the control member 5 moves along the track guiding groove 21 to the lower acting point 23. At this time, the switch valve is in an open state.

[0041] Furthermore, anti-slip lines 32 are provided on the upper part of the outer side surface of the key housing 3 to facilitate the rotation for adjusting the water flow rate.

[0042] Through the arrangement of the control member 5, the slider 2 and the guiding sleeve 1, a push-button switch can be realized, and at the same time, the function of rotating to adjust the flow rate can be realized; and through the arrangement of the track guiding groove 21 on the side surface of the slider 2 and the upper acting point 22 and the lower acting point 23 on the track guiding groove 21, a large-stroke sliding of the key housing 3 can be realized; and through the setting of the distances between the upper acting point 22 and the lower acting point 23, the adjustment of the pressing stroke distance can be realized.

[0043] As Figures 8 to 10As shown in the figure, the present invention also provides a valve assembly, which includes a switching valve 200 with a flow regulation function. The switching valve 200 includes a rotating part for regulating the flow by rotation, and a control part for controlling the opening and closing of the switching valve. It further includes the control device described above. The guide sleeve 1 acts on the rotating part for flow regulation. The slider 2 acts on the control part for opening or closing the switching valve. It should be noted that the push-button type switching valve 200 with a flow regulation function is already in the prior art, and its internal structure will not be specifically described here, so its internal structure is not shown in the drawings.

[0044] In this embodiment, as Figure 11 and Figure 12 shown, a control valve system is provided, which has a function of placing objects. The control valve system includes a housing 33. A plurality of water flow branches for connecting external water outlet devices are arranged inside the housing 33, and the valve assembly described above is arranged on the water flow branches. A through hole for the button housing 3 to slide up and down is arranged on the operation surface 34 of the housing 33. When the valve assembly is in the closed state, the pressing end surface of the button housing 3 is flush with the operation surface 34. When the valve assembly is in the open state, a part of the button housing 3 protrudes out of the operation surface 34. Through the setting of the side track guide groove 21 of the slider 2 and the upper action point 22 and the lower action point 23 on the track guide groove 21, the large-stroke sliding of the button housing 3 can be realized, that is, when the valve assembly is in the open state, the button housing 3 has enough height to be placed outside the operation surface, which is convenient for rotating to adjust the flow.

[0045] In other embodiments, the control valve system may also be as Figure 13 shown, which is a long strip shape with a plurality of valve assemblies for opening and closing multiple water circuits and flow regulation. As Figure 14 shown, it is an embedded control valve system, and a part of its housing is embedded in the wall, making the overall installation simple and neat.

[0046] Through the setting of the side track guide groove 21 of the slider 2 and the upper action point 22 and the lower action point 23 on the track guide groove 21, it can be realized that when the push-button type valve assembly 200 is in the closed state, the pressing end surface of the button housing 3 is flush with the housing end surface, which is more aesthetically pleasing. When the push-button type valve assembly 200 is in the open state, a part of the button housing 3 protrudes out of the housing end surface, so that it can be easily distinguished whether the water valve core is in the open state or the closed state through vision.
