Multifunctional switching valve and water outlet device thereof

Abstract

A multifunctional switching valve comprises an automatic ball pen type pressing mechanism, a sealing guide rod, a first spring and a valve element body. Through triggering of the automatic ball pen type pressing mechanism, the first spring can exert resilience opposite to pressing force to the sealing guide rod, the sealing guide rod constantly abuts against the pressing mechanism, the sealing guide rod reciprocates up and down in the axial position of the valve element body through the high-position and low-position stroke of the pressing mechanism, accordingly, a plug on the sealing guide rod can selectively block a first flow guiding hole or a second flow guiding hole, and opening / closing of a water inlet and a first water outlet or a second water outlet is finally achieved. meanwhile,through rotation of the included angle between the valve element body and a valve element base, the overflow area of a flow adjusting hole is changed, and accordingly the purposes of flow switchover and water temperature adjustment are achieved.

Description

technical field [0001] The invention relates to the field of sanitary ware, in particular to a multifunctional switching valve and a water outlet device equipped with the switching valve. Background technique [0002] Applying the principle of automatic ballpoint pen switching to the bathroom field first appeared in the patent literature of CN101793331A, such as Picture 1-1 , Figure 1-2 As shown, it discloses the working method of switching the waterway through the button, but this kind of waterway switching is limited to the water inlet 4' and at least two water outlets 5' perpendicular to each other, that is, if the water inlet 4' is located at the bottom of the valve body, Then the two water outlets 5' are located in the radial position of the valve body. This waterway switching method has a narrow application area and can only be applied to shower or top spray products; at the same time, when the switching valve body is placed horizontally, push the button After 6' ...

[0002] Applying the principle of automatic ballpoint pen switching to the bathroom field first appeared in the patent literature of CN101793331A, such as Picture 1-1 , Figure 1-2 As shown, it discloses the working method of switching the waterway through the button, but this kind of waterway switching is limited to the water inlet 4' and at least two water outlets 5' perpendicular to each other, that is, if the water inlet 4' is located at the bottom of the valve body, Then the two water outlets 5' are located in the radial position of the valve body. This waterway switching method has a narrow application area and can only be applied to shower or top spray products; at the same time, when the switching valve body is placed horizontally, push the button After 6' is pressed, because the button 6' has no self-weight limit, it is easy to form a virtual position, that is, the position of the button 6' after pressing may be consistent with the position of the button 6' in the pop-up state, and the stroke of the button 6' cannot be recognized at this time Position to determine which water inlet 4' is connected to which outlet 5'

[0003] In view of this, the industry has disclosed another button-type water outlet device, refer to the announcement number CN205036896U, such as Figure 2-1 , Figure 2-2 As shown, a radial water inlet 11a, a radially upper water outlet 12a, and a radially lower water outlet 13a are provided on the side wall of the water outlet body 1a, and the switching valve 2a is placed in the inner cavity of the water outlet body 1a. The pressing mechanism 5a drives the spool 3a to reciprocate along the axis of the switch valve 2a, so that one of the water inlet 11a can connect with the upper water outlet chamber 6a or the lower water outlet chamber 7a, thereby forming different switching waterways. The water inlet 11a and the upper and lower water outlets 12a, 13a are all located in the radial position of the switching valve 2a, which can facilitate the arrangement of the lifting rod and the hand-held shower on the water outlet device 1a, but this kind of scheme is in order to realize the valve core 3a It forms two closed waterways with the inner cavity of the switching valve 2a, so three sealing rings 32a need to be provided on the outer ring wall of the valve core 3a. The cavity wall generates friction, which causes the pressing mechanism 5a to generate greater frictional resistance when pressing; secondly, the sealing ring 32a will wear out during repeated friction, which will easily cause water leakage in the switching valve 2a, and the service life is low; at the same time The upper water outlet chamber 6a and the lower water outlet chamber 7a of this water outlet device are all arranged at the radial position of the switching valve 2a, so that when the valve core 3a switches the waterway, it is necessary to transfer the water in the upper water outlet chamber 6a or the lower water outlet chamber 7a. The waterway switch can only be realized after the squeeze is exhausted, so that the pressing mechanism 5a will produce a certain delay effect when pressing and switching

[0004] At the same time, the above two push-button switching valves cannot realize the function of flow switching or water temperature adjustment at the same time. If flow control or water temperature control is required, an additional flow control valve must be added to realize flow adjustment or temperature adjustment. , sometimes due to the limitation of the installation space, it is impossible to install, or considering the overall simple visual effect, both the flow regulating valve and the switching valve are installed on a water outlet device, and the overall layout is complicated
