Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of electron wind to compress switch, this electron wind compresses switch as shown in Figure 1, 2, comprising: upper cover 101, lower cover 102, malleation mouth 103, negative pressure mouth 104, blast barrier film 105, bracing frame 106, magnet ring 107, induction coil 108 and thin diameter spring 110; Wherein,
Electron wind compresses switch and is provided with diaphram tank 118(concrete structure and can is: the surrounding of upper cover 101 or lower cover 102 is provided with notch, and upper cover 101 and lower cover 102 coordinate and form diaphram tank 118; The periphery of blast barrier film 105 is arranged in diaphram tank 118, the blast barrier film 105 interior cavity that electron wind compressed switch is divided into malleation chamber 112 and negative pressure cavity 113, malleation chamber 112 is malleation mouth 103 with outside connected entrance, and negative pressure cavity 113 is negative pressure mouth 104 with outside connected entrance; Blast barrier film 105 and bracing frame 106 are fixing, and (concrete fixed form can be: blast barrier film 105 is also provided with at least two juts 1051, the position that bracing frame 106 is corresponding with jut 1051 is provided with fixing hole, the jut 1051 of blast barrier film 105 is fixed through this fixing hole and bracing frame 106, certainly its fixed form can also be, other fixed form is fixed or can also be to blast barrier film 105 and bracing frame 106 hot pressing, and the present invention does not limit to fixing concrete mode);
Bracing frame 106 is provided with magnet ring fixed part 1061, magnet ring 107 and magnet ring fixed part 1061 are fixed by socket; Lower cover 102 is provided with magnet bore 1021 at the correspondence position of magnet ring fixed part 1061, the surrounding of magnet bore 1021 is wound with induction coil 108, induction coil 108 is provided with two outputs, is provided with spring location division 109 in magnet bore 1021, and thin diameter spring 110 is located by spring location division 109.
Optionally, above-mentioned induction coil is specifically as follows: the induction coil of every layer of even coiling.Here adopt the induction coil of every layer of even coiling mainly to improve the linear character of inductance value, due to the coil of non-homogeneous coiling, the coil such as, used during washing machine water pressure sensor detects linear very bad.Increase the precision that linear character can well improve detection.
Operation principle of the present invention is specifically as follows, because cavity is divided into malleation chamber and negative pressure cavity by blast barrier film, because its accuracy of detection requires very high, so the zone of action thickness of blast barrier film can not be too thick, in order to avoid affect precision, the thickness of blast barrier film zone of action need ensure at below 0.25mm, the diameter of zone of action is at more than 50mm, blast diaphragm diameter needs at more than 55mm, when so just can make blast within the scope of 100pa, blast film has sensitive change, its Cleaning Principle is, when the pressure change of negative pressure cavity, the pressure differential of malleation chamber and negative pressure cavity by blast barrier film to pressing down, now, the magnet ring being fixed on magnet ring fixed part will move down, like this along with the difference of the distance of magnet ring movement, the inductance value of induction coil induction is also different, the distance of magnet ring movement just can be known like this by two delivery outlets of induction coil, thus the switch that control electron wind compresses switch, when the pressure differential of malleation chamber and negative pressure cavity diminishes, magnet ring rebounds initial position by thin diameter spring, it should be noted that, here thin diameter spring is specifically as follows the spring of linear diameter at 0.35 below mm of spring, because the blast of blast switch impression is little especially, if with the spring that wire diameter is thicker, the blast pressure of blast switch more originally cannot dead spring, so select thin diameter spring mainly here to improve the precision of blast switch.In addition, the switch that above-mentioned electron wind compresses switch is determined by the inductance value of induction coil, and relative to sensitive switch, much more stable than the mechanical signal of sensitive switch of electronic signal, also not easily break down, so it has the advantage reducing failure rate.In addition, structure provided by the invention is adopted to make the cost of blast switch substantially not have much changes, so it also has the low advantage of cost.
The zone of action of above-mentioned blast barrier film can be, the region of very thin thickness in blast barrier film, specifically can region between blast barrier film outer peripheral areas and zone line, wherein, the outer peripheral areas of blast barrier film is specifically as follows: be arranged on the region in blast groove, and the zone line of blast barrier film is specifically as follows: the region contacted with bracing frame.
Optionally, above-mentioned magnet ring fixed part 1061 is provided with spring jut, and this spring jut stretches in the mesopore of thin diameter spring 110.By arranging spring jut, thin diameter spring 110 can not be offset, because one end is provided with spring location division 109 and is located in magnet bore 1021, the other end is located by spring jut, so thin diameter spring 110 can only form displacement in the height direction, and the displacement of left and right can not be there is, which further increases the precision of blast switch.
Optionally, above-mentioned electron wind compresses switch and also comprises: oscillating circuit, and this oscillating circuit is connected with two outputs of induction coil 108.Increasing an oscillating circuit is to convert the inductance signal of induction coil to frequency signal, loss would not be formed to signal like this because of transmission range, because for inductance signal, if transmission range is longer, interference so for inductance signal is very large, especially electron wind provided by the invention compresses switch inherently a kind of high-precision blast detection means, more increases the requirement of interference, so can improve the precision of detection further after increasing oscillating circuit.
Optionally, above-mentioned electron wind compresses switch and also comprises: electronic control switch circuit, and this circuit is connected with oscillating circuit, identifies the change of frequency, and circuit exports according to the parameter set and opens or closes signal.
The present invention also provides a kind of gas utensil, and this gas utensil comprises above-mentioned blast switch.The gas utensil comprising above-mentioned blast switch has the high advantage of reliability.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
