Embodiment
Be below the specific embodiment of invention and by reference to the accompanying drawings, technical scheme of the present invention be further described, but invention is not limited to these embodiments.
Air-flow sensing device of the present invention is mainly used on washing machine water treater, produces signal feedback to the controller on washing machine water treater by the air-flow in the ozone generating-device in induction washing machine water treater.
See in figure, this air-flow sensing device mainly comprises pneumatic sensor 11 and mount pad, and 11 pneumatic sensors are arranged in mount pad.Mount pad comprises conduit 1 and permanent seat 2, conduit 1 is linked in ventpipe, when there being air-flow in ventpipe, the pneumatic sensor 11 be arranged in mount pad can sense the airflow signal in conduit, and signal is gathered, be transferred to by signal transmission line 42 on the controller of washing machine water treater.
Two of conduit 1 and ventpipe docking, forms a complete airflow pipeline, permanent seat 2 is fixed by socket on conduit 1, and permanent seat 2 is generally four prism type, can certainly be cylindrical, not do specific requirement here.Be provided with a pair connection ear 3 in the both sides of permanent seat 2, connect ear 3 and be provided with open-work, by bolt or bearing pin, connection ear 3 is fixed on the substrate of washing machine water treater, thus whole air-flow sensing device is fixed on washing machine water treater.
The inside of permanent seat 2 is provided with installation cavity, the middle part stretching into the part of permanent seat 2 installation cavity at conduit 1 is provided with a projection 9, projection 9 is provided with a through hole 43 identical with permanent seat 2 installation cavity opening direction, through hole 43 makes installation cavity and the inner conducting of conduit 1, thus the convenient air-flow responded to from outer setting pneumatic sensor 11 in conduit 1.
Also be provided with in the installation cavity of permanent seat 2 and connect bucket 4, connect bucket 4 and be fixed by socket in the projection 9 of conduit 1, the conveniently installation of pneumatic sensor 11, the height that the height connecting bucket 4 is greater than protruding 9.Because the connection inside of bucket 4 and the inside of conduit 1 are conductings, in order to when washing machine water treater works, air-flow can not run off from connection this one end of bucket 4, after installation pneumatic sensor 11, require pneumatic sensor 11 and connect between bucket 4 to seal.Therefore, when designing protruding 9, the setting of plane having been carried out to the opening portion of protruding 9, can fit by the sealing member 41 well and on pneumatic sensor 11.Ensure that in order to make sealing effectiveness pneumatic sensor 11 can not produce transposition in use causes induction of signal to go wrong better simultaneously, after installing sensor, and toward injecting glue in connection bucket 4.
Pneumatic sensor 11 responds to the air-flow in conduit 1 by inductive probe 40, if inductive probe 40 extend into the face of damming of conduit 1, then can have influence on the air flow rate in conduit 1 on the one hand, also easily produce wrong report on the other hand; If inductive probe 40 is away from the face of damming of conduit 1, when air-flow is less, then there will be the problem of induction less than airflow signal.Therefore, inductive probe 40 is arranged on through hole 43 and dams the opening portion in face for best near conduit 1.
The mounting face of permanent seat 2 is provided with the lid 74 supporting with permanent seat 2, four bights of lid 74 are provided with attachment pegs 20, the relative position in four bights of permanent seat is provided with four connection holes 6, by the cooperation of attachment pegs 20 and connection holes 6, lid 74 is snapped onto on permanent seat 2.Further, the opening portion of permanent seat 2 is provided with cascaded surface 8 near inner side, the convex tendon 21 matched with cascaded surface is provided with in the relative position of the mounting face of lid 74, make the connection between lid 4 and permanent seat 2 more reasonable, firm by the cooperation of convex tendon 21 and cascaded surface 8, make the water proof and dust proof better effects if of lid 74.
The oral area of permanent seat 2 is provided with a breach 5, and when lid 74 covers the mounting face of permanent seat 2, this breach 5 forms a threading hole, and the signal transfer limes 42 of pneumatic sensor 11 stretches out in permanent seat 2 through this threading hole.
Further, gap location between permanent seat 2 and conduit 1 is provided with gusset plate 10, gusset plate 10 covers the gap between permanent seat 2 and conduit 1 completely, serves the effect of dustproof and waterproof on the one hand, makes the structural stability between permanent seat 2 and conduit 1 better on the other hand.
As preferably, conduit 1, permanent seat 2, connect bucket 4 and gusset plate 10 all by injection moulding integrated molding, production efficiency is high, low cost of manufacture.Corner in permanent seat 2 between each wall is provided with bar-shaped trough 7, and bar-shaped trough 7 is arranged along the opening direction of permanent seat 2.In integrated injection molding process, permanent seat 2 is when sizing, and the wall of permanent seat 2 easily produces the situation of uneven thickness, by increasing bar-shaped trough 7, can effectively prevent the wall of permanent seat 2 from occurring the situation of uneven thickness.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
