Embodiment
Hereinafter with reference to accompanying drawing the preferred embodiments of the invention are described.
The stereographic map of Fig. 1 has illustrated the outward appearance of gas leakage detector of the present invention.As shown in Figure 1, this gas leakage detector comprises main body 1.The front portion of main body 1 is provided with the kind of the coal gas that is used for showing leakage and the display window 2 of amount.In addition, also be provided with on the top of main body 1 and be used for the operation knob 3 of operating main body 1.
The front view of Fig. 2 shows the inside of gas leakage detector of the present invention.As shown in Figure 2, be used to provide the power supply unit 7 of electric power to be arranged on the bottom of main body 1.Aspiration pump 10 is arranged on the pre-position in the main body 1, and the electric power that utilization offers aspiration pump 10 makes fan 14 rotations and sucks air to be detected.In addition, the unit 4 of bleeding is arranged on the pre-position in the main body 1 and engages with aspiration pump 10 rotation, is provided with the bleed-off passage 4a that is used for sucking air in the unit 4 of bleeding.
Fig. 3 is the amplification view of the part " A " among Fig. 2.The bleed-off passage 4a that is arranged in the unit 4 of bleeding is used for sucking coal gas from air.Coupling sleeve 5 is arranged on the pre-position of the unit 4 of bleeding, and its coal gas that is used for sucking flows to aspiration pump 10.End of over cap 6 sealing coupling sleeves 5 in case coal gas be discharged outside to.
In addition, be provided with filtrator 5b in the pre-position of over cap 6, it is used for removing the various impurity in the inhaled air, for example dust.
In addition, coupling sleeve 5 is installed in the outside of main body 1.Be provided with packing ring 9 in the pre-position of main body 1, in order to prevent allowing coupling sleeve 5 rotations when coupling sleeve 5 and main body 1 from throwing off.
Fig. 4 is the zoomed-in view of aspiration pump.This aspiration pump comprises the shell 10a that wherein makes bleed-off passage 10b.The mouth of pipe 11 is located at the upper end of shell 10a, and the flexible pipe 8 that links to each other with coupling sleeve 5 is enclosed within on the mouth of pipe 11.Catalytic combustion (catalytic combustion) type sensor 12 is located in the aspiration pump 10, in order to survey in the inhaled air whether have coal gas.Fan 14 is located at the bottom in the aspiration pump 10, in order to air is sucked aspiration pump 10.In addition, motor M is connected in order to drive fan 14 with fan 14.
Fig. 5 is the cut-open view along the A-A line acquisition of Fig. 4.As shown in the figure, catalytic combustion-type sensor 12 detect rotation by fan 14 suck whether have coal gas in the air in the aspiration pump 10 after, the exhausr port of being located on fan 14 offsides 15 will be discharged air.
Fig. 6 shows the operation of the unit of bleeding.The unit 4 of bleeding is connected in coupling sleeve 5 and can be according to predetermined direction around coupling sleeve 5 rotations.
The using and the operate as follows of gas leakage detector that constitutes according to foregoing.
At first, bleed unit 4 with a predetermined direction rotation and a manipulation operations knob 3 in order whether to contain coal gas in the detecting air, to make.By manipulation operations knob 3, thereby electric power is offered motor M drive fan 14.
Along with the rotation of fan 14, air is inhaled into by the bleed-off passage 4a of the unit 4 of bleeding.Inhaled air is sent into aspiration pump 10 after continuously by coupling sleeve 5 and flexible pipe 8.
On this stage, the bleed-off passage 4a of the unit 4 of bleeding is communicated with the hole 5a of coupling sleeve 5.Thereby although bleed the given angle of unit 4 rotations, air also enters aspiration pump 10 easily.
In addition, seal member 6a and the over cap 6 that is located at an end of coupling sleeve 5 prevents that the air that enters coupling sleeve 5 is discharged in the external environment condition thus.
Because filtrator 5b is located at the pre-position of over cap 6, so filtrator 5b can remove by all contaminations in unit 4 inhaled airs of bleeding, for example dust.
Next, air is inhaled into aspiration pump 10.Be located in the aspiration pump 10 and survey the air that is drawn in the aspiration pump 10 and whether contain coal gas by the catalytic combustion-type sensor 12 that a kind of agglomerated material is made.The coal gas amount and the kind that detect are presented on the display window 2.
The air that flows through catalytic combustion-type sensor 12 is discharged to outside the main body 1 via the exhausr port on the offside that is located at fan 14 15.
Catalytic combustion-type sensor 12 has thin perforation.Therefore, when fan 14 rotation when air being sucked in the aspiration pump 10, air will flow through catalytic combustion-type sensor 12, make catalytic combustion-type sensor 12 can survey coal gas thus and whether exist.The air that sucks aspiration pump 10 is disposed to the external world by exhausr port 15.
Catalytic combustion-type sensor 12 is supported on the precalculated position of aspiration pump 10 by support 13.Therefore, when catalytic combustion-type sensor 12 lost efficacy, the catalytic combustion-type sensor 12 that can easily more renew by removing support 13 from aspiration pump 10.
Briefly, when power supply unit 7 when motor M provides electric power, fan 14 by the motor M driven rotary so that air is sucked among the bleed-off passage 4a of the unit 4 of bleeding.In the coupling sleeve 5 that inhaled air flows into bleed-off passage 4a is communicated with, and filtrator 5b removes the impurity in the inhaled air.Then, airflow is through flexible pipe 8 and be admitted to aspiration pump 10.The catalytic combustion-type sensor 12 that is located in the aspiration pump 10 and comprises a kind of agglomerated material surveys in the inhaled airs whether contain coal gas.Discharge via the exhausr port 15 of the bottom that is located at aspiration pump 10 through the air of surveying.
Like this, device of the present invention sucks also to survey in the inhaled air whether contain coal gas, thereby avoids the mishap that takes place because of gas leak.
In addition, according to the present invention, the unit of bleeding can rotating certain angle.Therefore, even this gas leakage detector can easily suck air from a little space, thereby allow the user can easily determine whether there is coal gas in the little space.Gas leakage detector of the present invention can use a kind of rechargeable battery, thereby easy to carry and use.
This gas leakage detector can carry and use easily.In addition, the unit of bleeding of this gas leakage detector can rotate given angle, thereby can allow the user easily determine whether to exist gas leak in the place (as gas cooker, gas valve or gas water heater) that coal gas leaks probably.
Obviously, for the person of ordinary skill of the art, all be possible to many modifications and variations of the present invention.
Can recognize that application of the present invention is not limited to above-mentioned concrete structure, under the situation that does not deviate from the spirit and scope of the present invention that are defined by the following claims, to various modifications of the present invention, interpolation with to substitute all be possible.
As mentioned above, the invention provides a kind of gas leakage detector, its utilize aspiration pump to suck and detecting air in or the inflammable gas in the place that may leak such as coal gas such as gas cooker, gas valve or gas water heaters, thereby prevent the mishap that causes because of gas leak.And this gas leakage detector can use rechargeable battery, thereby allows the user can easily carry this detector, and can make gas leakage detector anywhere can carry out air thus to suck and survey.
In addition, the unit of bleeding can rotate given angle, just can store this gas leakage detector easily thereby allow the user survey the unit rotational of only need bleeding after finishing in gas leak.
