Abstract
The utility model relates to a negative pressure air ventilating machine for removing odour from closet, comprising an electromotor with a rotation speed of 3000 to 10000 r/m, an impeller and a case body. The impeller of the electromotor is fixed at the shaft of the electromotor and faces to the negative pressure air-breathing port of the case body; the other end of the case body is an air outlet. The advantages are that: first, the adoption of the negative pressure air ventilating machine guarantees the negative pressure for the defecating body sucking odour and removing odour; second, the design of the negative pressure air ventilating machine is an integral structure, so the installation has convenience and the utility model can match with the air outlet of the present house building.
Description
Technical field:
The utility model relates to a kind of deodorizing formula water closet special negative pressure air exhauster, belongs to the water closet air exhauster and makes the field.
Background technology:
All notice of authorization CN2239456Y of the applicant, title " deodorizing formula water closet ".This water closet comprises water closet, ring and defecation body, the row's of having foul smell mouth on the defecation body, row's foul smell mouth communicates with drain in the defecation body, the air inlet port of air exhauster by pipeline with arrange the foul smell mouth and be communicated with, the exhaust opening of air exhauster leads to stack or logical atmosphere by pipeline.It is not enough point: the one, smelly mouthful of the row on the defecation body of this deodorizing formula water closet communicates with drain in the defecation body, because drain is a plurality of, can't realize that therefore negative pressure arranges smellyly, does not reach the purpose of deodorizing; The 2nd, because the rotating speed of air exhauster does not form negative pressure, do not reach the purpose of deodorizing equally.
Summary of the invention:
Purpose of design: avoid the weak point in the background technology, design a kind of air exhauster that will have now in the background technology, be designed to be able to produce the negative pressure ventilation machine of negative pressure, this negative pressure sucks the foul smell in the defecation body in the connecting leg by connecting leg and enters atmosphere by the negative pressure ventilation machine; The 2nd, inhale the smelly effect of smelly row in order to guarantee negative pressure, the negative inspiratory pressure through hole at defecation body or ring rear portion is one; The 3rd, for the ease of installing, the negative pressure ventilation machine is designed to overall structure.
Design scheme: being positioned at the drain of negative inspiratory pressure through hole on defecation body or the ring and defecation body not connected is one of characteristics of the present utility model, purpose to guarantee negative-pressure sucking that the negative pressure ventilation machine produced by connecting leg the foul smell in the defecation body can be sucked timely and effectively connecting leg, outlet by the negative pressure ventilation machine enters atmosphere.Secondly, it is two of characteristics of the present utility model that air exhauster is designed to the negative pressure ventilation machine, and purpose guarantees to have enough negative-pressure suckings to produce.The 3rd, it is three of characteristics of the present utility model that the negative pressure ventilation machine is designed to overall structure, and purpose is convenient to convenient the installation, is complementary with exhaust opening in the existing residence building.Its technical scheme: the negative pressure ventilation machine, constitute by motor, impeller and the housing of 3000～10000 rev/mins of turn ups, the impeller of motor is fixed on the motor reel and directly to the negative inspiratory pressure mouth of housing, the housing another port is an exhaust opening.
The utility model is compared with background technology, and the one, the employing of negative pressure ventilation machine has guaranteed that the defecation body inhales the smelly required negative pressure pressure of smelly row; The 2nd, the negative pressure ventilation machine is designed to overall structure, not only convenient the installation, and can be complementary with the exhaust opening in the existing residence building.
Description of drawings:
Fig. 1 is the structural representation of squat type deodorizing toilet.
Fig. 2 is the structural representation of negative pressure ventilation machine.
The specific embodiment:
Embodiment 1: with reference to accompanying drawing 1～2.Negative pressure deodorizing formula water closet, it comprises water closet 1, ring 2 and defecation body 7, have negative inspiratory pressure through hole 6 on the defecation body 7 and be communicated with the pit of defecation body, negative pressure ventilation machine 5 by connecting leg 4 directly will be in the foul smell suction pipe logical atmosphere.Defecation body 7 adopts pottery or artificial ceramic making, and its manufacture craft is a prior art, is not described herein at this.Motor in the negative pressure ventilation machine 5, briefly as the motor that dust catcher adopted, it can be to exchange or direct current.
Embodiment 2: with reference to accompanying drawing 2.The negative pressure ventilation machine is made of motor 10, impeller 9 and the housing 11 of 3000～10000 rev/mins of turn ups, and the impeller 9 of motor is fixed on the motor reel and directly to the negative inspiratory pressure mouth 8 of housing, the housing another port is an exhaust opening 12.Negative inspiratory pressure mouth 8, impeller 9, housing 11 adopt the mold injection one-shot forming, and motor is made and adopted prior art to get final product, but will satisfy its rotating speed.
