Embodiment approach 1

[0032] Such as figure 1 , the valve seat 11 is provided with an inlet port 11J and three outlet ports 11KA, 11KB, 11KC, with the direction of the inflow pressure fluctuation, that is, the up and down direction in the figure, as the axial direction, and the three outlet ports 11KA, 11KB, 11KC facing sideways and arranged around the circumference. Such as figure 2 , the valve core 12 is installed in the valve bracket 11A of the valve seat 11 and is located between the inlet port 11J and the outlet port, its inlet port 12J is connected to the inlet port 11J, and its upstream part (used to accept the inlet impact) The position) is aligned with the inflow communication port 12J, and its upper half is equipped with a moving block 128. The upper guide groove housing 1171 and the lower guide groove housing 1172 as the trajectory limiting structure are installed on the valve seat 11 (see for details image 3 ), enclosing a zigzagging closed-loop guide groove (after unfolding into a...

Embodiment approach 2

[0038] Such as Figure 5 , the valve seat 21 is provided with an inlet 21J and two outlets 21KB, 21KF, and the two outlets 21KB, 21KF are arranged along the ups and downs direction of the inlet pressure, that is, the up and down direction in the figure. The valve core 22 is installed in the valve seat 21 and is located between the inlet port 21J and the outlet port. A trajectory defining structure 227 is provided. The guide rod 218 is installed on the valve seat 21 and can rotate around its installation fulcrum 218A, and its moving end 218B is defined by the track limiting structure 227 to move in a cyclical track. The above-mentioned structure constitutes the pressure conversion structure of the passive switching valve, so that the valve core 22 moves with the fluctuation of the inflow pressure, and can be driven by the inflow pressure to switch the outlet corresponding to the outflow communication port 22K. The specific working process is described in detail as follows . ...

Abstract

Disclosed are a passive automatic switching valve and an automatic cleaning apparatus comprising the passive automatic switching valve. The passive automatic switching valve is used in places where effluent passages of fluids such as water and a gas are switched. The passive automatic switching valve comprises a valve seat (11, 12) and a spool (12, 22), wherein the valve seat (11, 12) is provided with an inlet (11J, 21J) and outlets (11KA, 11KB, 11KC, 21KB, 21KF); the spool (12, 22) is mounted in the valve seat (11, 12) and located between the inlet (11J, 21J) and the outlets (11KA, 11KB, 11KC, 21KB, 21KF); and an influent communicating port (12J, 22J) of the spool (12, 22) abuts against the inlet (11J, 21J), and a plurality of outlets (11KA, 11KB, 11KC, 21KB, 21KF) of the valve seat (11, 12) are provided. When the spool (12, 22) is driven, an effluent communicating port (12K, 22K) thereof is switched between the plurality of outlets (11KA, 11KB, 11KC, 21KB, 21KF). The passive automatic switching valve is provided with a pressure switching structure, so that the spool (12, 22) can move under the drive of influent pressure as the influent pressure fluctuates, thereby realizing switching, not needing to additionally arrange complex structures such as an electric control, occupying a small space, reducing costs, and facilitating maintenance.

Description

technical field [0001] The invention relates to an automatic switching valve, which is used for switching the outflow channels of water, gas and other fluids, for example, it is used in the water supply pipeline of automatic cleaning equipment. Background technique [0002] Referring to the patent document CN202510737U, it discloses a push-button diverter valve. Through the guiding action of multiple sets of inclined surfaces and the reset action of the spring, the valve stem rotates at a certain angle each time it is pressed due to the guiding action of a set of inclined surfaces. The guide of a group of slopes is rotated by a certain angle, and the sum of the two rotation angles is the angular displacement generated by each operation, and each operation realizes the switching of the outlet port; the inlet port is on the side, and the two outlet ports are set on the side. below. [0003] The spring pen is a pen with a wide range of applications. Through the mutual guidance...
