A center in a front end of the spray cup is provided with an oval spraying hole, the longitudinal cross-section of the spraying hole is U-shaped, a cylinder hollow cavity is arranged at a back part of the spraying cup, and a front end of the nozzle body is arranged in the cylinder hollow cavity of the spraying cup. The nozzle body is a hollow cylinder, the spraying core is arranged in the middle part of the nozzle body, and a current stabilizer at one end of the spraying core is fixed with a back part of the nozzle body. After installing the nozzle, each component can not relatively move, so the utility model has the advantages of high utilization reliability, long service life and good effect.
Description
The utility model relates to a kind of critical component of cooking fume remover, particularly a kind of three grades of formula fume purifying nozzles.Belong to the technical field that cooking fume remover is made.
In order to remove heat steam, oil smoke and the toxic gas in the kitchen and to clean the smoke exhaust internal part, the applicant has proposed a series of solution, and successively applied for patent to Patent Office of the People's Republic of China, the most representative is " automatic flue purifier for household ", number of patent application is: 97236428.5, yet influencing one of the purifying rate of such cooking fume remover and key factor of cleaning rate is exactly nozzle.A main method of this cooking fume remover oil removing, purification is exactly after the water that contains cleaning agent is atomized by nozzle, spray to and contain the oil and the heat steam inlet port of toxic gas, in a strip broad band region, fully mix and reach the purpose of highly oil removing, purification with heat steam.Therefore, the performance of deoiling effect and nozzle is closely related.Because be subjected to the restriction of cooking fume remover structure, the cooking fume remover air inlet is a strip, desires to make the air inlet place to be covered fully by water smoke, and forms the water smoke zone of a broad, the water smoke of nozzle ejection should have directionality, shape and certain range.In addition, pressure, the flow of pump also are restricted, and this just has influence on the atomizing and the spreading of spray of nozzle.From use occasion, because the water spray chamber wind speed is very big, it is good atomize, and drop diameter is little, and then water loss is big, needs appropriate drop diameter and intensity of dripping water, at last on dependability, and the too small easy obstruction of spray nozzle.Therefore up to the present, also there is not a kind of fume purifying nozzle that can overcome the above problems.
The purpose of this utility model provides that a kind of discharge coefficient is higher, and design pressure difference is lower, and atomization is good, and water loss is little, and water smoke has direction and shape, three grades of formula fume purifyings of service-strong nozzle.
Three grades of formula fume purifyings of the present utility model mainly are made up of shower nozzle, nozzle body, spray core with nozzle, and wherein the front end center of shower nozzle is provided with an oval spray orifice, and oval spray orifice longitudinal cross-section is
Shape is that a front portion is the spherical cylindrical hole of semicircle in the inner dome-like cavity that communicates with oval spray orifice of shower nozzle, and the rear portion of shower nozzle is a cylindrical cavity, and the front end of nozzle body is fixed in the cylindrical cavity of shower nozzle.Nozzle body is a hollow cylinder, the front portion of nozzle body hollow core body portion is a hollow cone, middle part and rear portion are hollow cylinder, promptly be provided with arc chord angle at the hollow cylinder front end with the end that hollow cone joins, the spray core is positioned at the centre of nozzle body, the front portion of spray core is a refractile body, at the refractile body rear portion is a small cylinder, the middle part of spray core is a cone, the front end and the small cylinder of cone join, the rear end of cone links to each other with flow straightener, is provided with through hole on the circumference of flow straightener, and the flow straightener and the nozzle body rear portion of spray core fix.After shower nozzle, nozzle body, spray core install, form a collision cell between the cone by hollow cylinder body portion in the nozzle body and spray core, the current of being injected by the flow straightener through hole at spray core rear portion produce first order atomizing in this collision cell.The hollow cone of nozzle body front portion forms the refraction chamber with spray refractile body in the heart, enter this refraction chamber by the water after the first order atomizing and carry out second level atomizing, form membranaceous water layer to penetrating all around along refraction chamber taper surface, under the tension force effect of water, dispersion is thinner water droplet.The water that atomizes through the second level enters the oval spray orifice of shower nozzle at last, carries out three grades of atomizings and ejection.Water smoke laterally is being the thin current shape of covering of the fan, and vertical direction is subjected to shower nozzle
The restriction of shape opening, water smoke is by directed by force.
Advantage of the present utility model is:
1. discharge coefficient is higher, and design pressure is lower, and atomization is good.
2. water smoke has directionality and certain shape, the oil smoke porch all can be covered.Form a generouser water smoke zone at the exhaust gas entrance place, guarantee that water smoke fully mixes with waste gas.
3. to drip the footpath moderate for water smoke, hits the intensity height, and the loss of water is less under the use occasion of high flow rate.
4. after installing between the jet parts, no relative motion, the dependability height, the life-span is long, is suitable for various cooking fume removers.
Fig. 1 is a general structure schematic diagram of the present utility model.
Fig. 2 is the Facad structure schematic diagram of shower nozzle.
Embodiment of the present utility model is as follows:
