A valve core group switching control mechanism

Abstract

The invention discloses a valve element group switching control mechanism. The valve element group switching control mechanism comprises at least two valve elements and further comprises at least two key modules and a first elastic piece. Each key module comprises a key for opening the corresponding valve element and a control rod, wherein the keys and the valve elements are correspondingly matched; each control rod can be assembled on the corresponding key in a way of being capable of moving along the axial direction of the corresponding key; a locking structure for locking the corresponding key is matched between each control rod and the corresponding key. The control rods of at least two key modules are coaxially linked; the control rod of at least one key module is connected with the first elastic piece for resetting; any one key at a resetting state is used for opening the corresponding valve element in a pressing manner and drives each control rod to do the axial movement; the corresponding control rod is used for driving the corresponding locking structure through resetting to lock the pressed key; the residual control rod is used for driving the corresponding locking structure through axial movement to unlock the corresponding pressed key, so that the key is reset. With the adoption of the structure, the valve element group switching control mechanism can be used for realizing linkage type switching control of at least two valve elements.

Description

technical field [0001] The invention relates to a switching control mechanism, in particular to a valve core group switching control mechanism. Background technique [0002] At present, the spools in the prior art include rotary spools, push spools and the like. Among them, the push-type spool, as the name suggests, opens and closes its waterway by pressing. The traditional push-type spool mainly realizes operation control by pressing its joystick. When there are multiple push-type spools that need to be switched When the water comes out, it can only be realized by one-by-one operation. For example, first close the push-type valve core that does not need water outlet, and then open the push-type valve core that needs water outlet, which makes the operation very troublesome and inconvenient to use. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a control mechanism for switching valve core...
