Utility model content

For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a new combustible gas probes Design scheme, can effectively realize outside the detecting function to fuel gas, realize without in addition being installed using tool, as long as having Purpose just can be used in socket.

The utility model adopts the following technical solution realizes:

A kind of combustible gas probe enters shell through the blow vent including being equipped with the shell of blow vent and for detecting Air in whether there is fuel gas detector module；The shell sets at least two pin through-holes, the detector mould Block is fixed in the shell and is equipped at least two power pins being welded on circuit board, and the shell is corresponding to be equipped with For the pin through-hole that the power pin stretches out, combustible gas detecting module is small in size, and function is sensitive, can effectively realize detection Function, have the presence of pin that can power directly to detector circuit, while saving cable, detector can be fixed on On wall, cabling or no the problem of reserving installation space are saved.

Preferably, the shell includes first shell and second shell, the first shell have cover board and from cover board to Several screw columns that second shell is integrally extended, several screw columns pass through several first installations of the detector module Hole is fixed to the second shell, passes through the second mounting hole in the second shell.Preferably, the pin through-hole is arranged in institute State second shell.

Preferably, the detector module includes circuit board and is mounted on the inspection of the circuit board towards the cover board side Slowdown monitoring circuit, at least two power pin are stretched out from the circuit board other side towards the second shell.

Preferably, the first shell is equipped with first through hole, switch is electrically connected to the circuit across the first through hole Plate.

Preferably, the first shell is equipped with circular vent lid.

Preferably, the edge of the circular vent lid is equipped with cyclic annular zone of aeration, the ring-type zone of aeration is equipped with ventilation hole.

Preferably, the second shell is equipped with cyclic annular side wall, at least there are four ventilating zones in the ring-type side wall, it is described Ventilating zone has ventilation hole.

Preferably, the first shell is equipped with cyclic annular side wall, at least there are four ventilating zones in the ring-type side wall, it is described Ventilating zone has ventilation hole.

Preferably, four ventilating zones are opposite two-by-two.

Compared with prior art, the utility model has the beneficial effects that:

The combustible gas probe of the utility model is saved by replacing cable to provide power supply to detection circuit with pin The use of cable, while jack can be injected, the operation hung and hung is saved, is realized without installation, the purpose of plug and play.

Specific embodiment

In the following, the utility model is described further in conjunction with attached drawing and specific embodiment,

As shown in Fig. 1-Fig. 2, the combustible gas probe of the utility model embodiment, including shell 1, for detect warp The blow vent enters in the air of shell the detector module 2 that whether there is fuel gas, and shell 1 includes first shell 11 With second shell 12, the first shell 11 of the present embodiment has generally circular cover board, and second shell 12 is with substrate and certainly The side wall that substrate extends to side, detector module 2 are fixed between first shell 11 and second shell 12, detector module 2 Equipped with 3 power pins 21, power pin 21 may pass through the pin through-hole 121 that second shell 12 is set, detector module 2 and power supply Pin 21 connects the use that can save cable, and can directly find jack in most of occasions and use, and adapts to numerous occasions, As long as thering is socket to plug energization to use, without other installation operations.

Detector module 2 includes circuit board and is mounted on detection circuit of the circuit board towards cover board side, and power supply is inserted Foot 21 is stretched out from the circuit board other side towards second shell 12.

First shell 11 integrally extends 3 mounting posts 112 to second shell 12, and mounting post 112 passes through detector module 2 The first mounting hole 22 and second shell 12 the second mounting hole 122, by first shell 11, detector module 2 and second shell 12 fixations are integral.

Power pin 21 passes through pin through-hole 121, and the shape of pin through-hole 121 is also consistent with the shape of power pin 21, Pin 21 can not generate in pin through-hole 121 to be rocked.
