Abstract
The utility model relates to a magnetic induction type pressure difference switch, which comprises a shell lower cover 1, an adhesive film 2, a magnet 3, a shell upper cover 4 and a magnetic induction device 6. The magnetic induction type pressure difference switch is characterized in that the shell lower cover 1 and the shell upper cover 4 are fixedly connected together. The adhesive film 2 embedded with the magnet is fixed at the middle part of the shell lower cover 1 and the shell upper cover 4 to be assembled together. The magnetic induction device 6 is arranged on the outer side of the shell upper cover 4 and is positioned corresponding to the magnet 3. According to the technical scheme of the utility model, under the action of the elasticity of the adhesive film 2 and the pressure difference, the magnet 3 is driven to conduct the reciprocating motion towards the magnetic induction device 6. Therefore, the magnetic induction device 6 is switched on to realize the on-off state of the circuit.
Description
Technical field
The present invention relates to electric heater field, be specifically related to the syndeton of a kind of magnetic inductive pressure differential switch of electric heater.
Background technology
Pressure differential switch, is widely used in electric heater field, and its Starting mode is mainly to carry out jack-up glued membrane by pressure differential, and the thimble that makes to be arranged on glued membrane moves to electrical equipment contact mechanism direction, and thimble promotes electrical equipment contact mechanism and makes connecting and disconnecting of the circuit.The patent No. is 201220202474.0 to be exactly a kind of pressure differential construction of switch, the thimble half of this kind of structure is arranged on inside cavity and glued membrane links together, half contacts with electrical equipment contact mechanism in cavity outside, the sealing of thimble and cavity must have a sealing device, there is the hidden danger of leaking in this structure, and thereby the thimble frictional force that must overcome sealing device in motion just can move back and forth and realizes the function of connecting and disconnecting of the circuit, just can have enough pressure differentials to promote thimble in order to overcome very large that the area of the general glued membrane of this frictional force must design, if glued membrane area is little, the pressure differential that promotes so thimble also must improve, so often just can not use in a lot of low hydraulic pressure area.
The purpose of this utility model is exactly the magnetic inductive pressure differential switch that a kind of area non-thimble-type that little, low hydraulic pressure can start is provided in order to overcome weak point of the prior art.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of syndeton of magnetic inductive pressure differential switch more reliably.
The utility model solves the problems of the technologies described above adopted technical scheme: the syndeton of improvement pressure differential switch, comprise: housing lower cover 1, glued membrane 2, magnet 3, case top lid 4, magnetic-inductive device 6, the utility model embeds magnet 3 on glued membrane 2, magnetic-inductive device 6 is placed in to case top lid 4 outsides corresponding with the position of magnet 3 simultaneously, utilize the elasticity of glued membrane 2 and pressure differential to promote magnet 3 simultaneously and move reciprocatingly to magnetic-inductive device 6 directions, thereby make magnetic-inductive device 6 work realize connecting and disconnecting of the circuit.
The utility model is in the time of design magnetic inductive pressure differential switch, cancel traditional thimble structure, reduce the hidden danger of leaking, with reduced design area, utilize cleverly the water resistance of water channel to realize the pressure differential conversion between two cavity A of pressure differential switch and B simultaneously, compact conformation, saving space, assembling easily.
Accompanying drawing explanation
Fig. 1 is the water route schematic diagram of the utility model embodiment.
Fig. 2 is the decomposing schematic representation of the utility model embodiment
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As depicted in figs. 1 and 2, a kind of pressure differential switch of the present utility model, comprise: housing lower cover 1, glued membrane 2, magnet 3, case top lid 4, fixed screw 5, tongue tube 6, circuit board 7, it is characterized in that: described housing lower cover 1 and case top lid 4 use fixed screws 5 are fixed together, the centre that the glued membrane 2 that is embedded with magnet 3 is fixed on described housing lower cover 1 and case top lid 4 assembles; Described magnet 3 is placed in the centre of glued membrane 2.Described housing lower cover 1 and case top lid 4 all have blasthole.The blasthole 1-1 of described housing lower cover 1 is connected with water inlet 8, and the blasthole 1-2 delivery port 9 of described case top lid 4 is connected.On described circuit board 7, be welded with tongue tube 6, it is corresponding with the position of magnet 3 that described tongue tube 6 is placed in case top lid 4 outsides;
As shown in Figure 1, when delivery port 9 is opened, in the time that fluid enters housing lower cover 1 from water inlet 8, fluid is divided into two-way, flow out from delivery port 9 through the water channel 10 of housing lower cover 1 on one tunnel, simultaneously the water route of delivery port 9 with by the water inlet 1-of case top lid 4, B is connected with cavity, another road flows into cavity A through the blasthole 1-1 of housing lower cover 1, now the hydraulic pressure of cavity A is greater than cavity B by the water resistance effect of water channel 10, thereby the magnet 3 that water pressure promotes on glued membrane 2 contacts and makes circuit turn-on to tongue tube 6 direction motion triggers tongue tube 6;
As shown in Figure 1, in the time that described delivery port 9 is closed, running water stops flowing, and pressure differential switch cavity A and cavity B hydraulic pressure are identical so as seen in Figure 1, utilize original elastic webbing moving magnet 3 of glued membrane 2 to be returned to home position, thus tongue tube 6 disconnect make circuit disconnect.
