Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0032] like figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown in the figure, a high-power electronic switch without frequent start-up includes a housing 1 and a housing cover 2 buckled on the housing 1. The lower side of the housing 1 is provided with an inlet connector 3, and the upper side is provided with an outlet connector 4. The inlet joint 3 and the outlet joint 4 are arranged in a staggered manner, and the inlet joint 3 and the outlet interface 4 are communicated through a stacked conversion channel 8. A flow measuring area is arranged inside the inlet joint 3, and above the stacked conversion channel 8 A check valve 6 is provided. The check valve 6 blocks the inlet joint 3 under the action of gravity, and moves upward under the action of water pr...

Abstract

The invention relates to the technical field of switches, in particular to a high-power electronic switch capable of avoiding frequent starting. The switch comprises a casing and a casing cover buckled on the casing; an inlet joint is arranged on the lower side of the casing; an outlet joint is arranged on the upper side of the casing; the inlet joint and the outlet joint are staggered and communicate with each other through a stacking and switching channel; a flow measuring area is arranged inside the inlet joint; a check valve is arranged above the stacking and switching channel; the check valve blocks the inlet joint under the effect of gravity, moves upwards under the effect of water pressure and finally enables the inlet joint to communicate with the stacking and switching channel; acircuit board is fixedly mounted on the inner side of the casing cover; and a pressure sensor for detecting outlet pressure is mounted on the side wall of the outlet joint and is electrically connected with the circuit board. The switch has the advantages as follows: the probability of frequent starting of a water pump is reduced, the stacking and switching channel is arranged, a water inlet and awater outlet of a pipe have the fall being 8 mm, and the difference between the flow of the water inlet and the flow of the water outlet is smaller than 0.1 m<3> / H.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to a high-power electronic switch without frequent starting. Background technique [0002] The traditional water pump electronic switch adopts a tank design, and there is no drop design between the water outlet and the water inlet. Although the diameter of the water outlet can be made large, the diameter of the water inlet is limited, so the overall water performance is greatly affected. [0003] When the relay is used for inductive loads, a high voltage will be generated at the moment the relay is disconnected, which will cause the relay to be shocked and cause spark discharge, which will greatly reduce the life of the relay. Therefore, the design power of the water pump controller is usually half or even higher than the rated power of the relay. Low, which is one of the reasons why the electronic switching power is generally low. [0004] In the water pump pressure control syste...
