Multifunctional changeover valve and water distributing device thereof

Abstract

The invention discloses a multifunctional changeover valve. The multifunctional changeover valve comprises an automatic ball-point pen type pressing mechanism, a sealing guide rod, a first spring and a valve element body, wherein the automatic ball-point pen type pressing mechanism is triggered, and the first spring applies return force opposite to pressing force to the sealing guide rod, so that the sealing guide rod abuts against the pressing mechanism all the time; the pressing mechanism has high stroke and low stroke, so that the sealing guide rod performs up and down reciprocating motion along the axial position of the valve element body, and therefore, the first flow-guide hole or a second flow-guide hole is selectively plugged by a plug on the sealing guide rod, and a water inlet and a first water outlet or a second water outlet are opened/closed; and an included angle between the valve element body and a valve element seat body is rotated, so that an over-flow area of a flow regulating hole is changed, and therefore, the flow switching purpose is realized.

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 push-button water distribution 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 diversion body 1a, and the switching valve 2a is placed in the inner cavity of the water diversion body 1a. The pressing mechanism 5a of the principle drives the valve core 3a to reciprocate along the axis of the switch valve 2a, so that one of the water inlet 11a and the upper water outlet chamber 6a or the lower water outlet chamber 7a can be connected to each other, thus forming different switching waterway
