Accompanying drawing explanation
Fig. 1 is the cutaway view of the antidrip fine mist spray head of the utility model one embodiment.
The specific embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is further described.
As shown in Figure 1, the utility model discloses a kind of antidrip fine mist spray head, comprise nozzle body 5, the joint 4 being axially connected with nozzle body 5, nozzle body 5 setting that communicates with joint 4, in nozzle body 5, be distributed with a plurality of micro nozzles, the cavity for intake tunnel forming at nozzle body 5 and joint 4 is provided with hermetically-sealed construction.Hermetically-sealed construction is arranged in the cavity as intake tunnel, comprise sealing-plug 1 and be fixed on elastic device 2 on sealing-plug, during original state, the length of hermetically-sealed construction integral body is not less than the length of cavity, so that hermetically-sealed construction keeps certain pressure after installation, thereby current cannot pass through during the less pressure in intake tunnel place.One end face of the sealing-plug 1 of hermetically-sealed construction and the liquid flow hole of joint 4 join, the other end of sealing-plug 1 is fixedly connected with the head end of spring assembly 2, the tail end of elastic device 2 and the inlet opening of nozzle body join, and the diameter of spring assembly 2 is greater than the aperture of inlet opening.During variation in water pressure in intake tunnel, the length of hermetically-sealed construction and the hydraulic pressure size in aquaporin are inverse ratio and change, when hydraulic pressure increases, hermetically-sealed construction length is dwindled, and sealing-plug 1, away from the liquid flow hole of joint 4, can enter in micro nozzle by intake tunnel water source to open intake tunnel.
In the present embodiment, sealing-plug 1 is the symmetrical structure of ball cap shape, elastic device is spring, sealing-plug 1 comprises for the spheroid portion of plugging fluid discharge orifice and for the cylinder part of fixing spring, the diameter of spheroid portion is greater than the aperture of liquid flow hole, and spherical end surface is towards pipe joint so that in hermetically-sealed construction during in initial state, sealing-plug 1 can be blocked liquid flow hole, the diameter of cylinder part is less than the diameter of spheroid portion, spring housing is connected on the cylinder part of sealing-plug 1, and the external diameter of spring is greater than the aperture, inlet opening of nozzle body, thereby prevent that whole hermetically-sealed construction landing is to nozzle body.Under the effect of the pressure of spring, the spherical end surface of sealing-plug 1 contacts with the liquid flow hole of joint, plays the effect that sealing prevents water clock.Sealing-plug 1 adopts anti-corrosive rubber to make as 4 third fluorubber, when meeting requirement of strength, can adapt to again the corrosion resistant requirement of long use, and pipe joint 4, nozzle body 5 are stainless steel material with elastic device 2, have good decay resistance.
Its operation principle is as follows: the fine mist spray head shown in the utility model is arranged on pipeline by joint 4, when water mist system does not start, ducted pressure is less, hermetically-sealed construction also, when original state, due to the pressure of elastic device, makes to keep sealing state between sealing-plug and joint 4, therefore pressure hour, the not conducting of whole inlet channel, current can not flow out from micro nozzle, thereby prevent the generation of weeping.When water mist system starts, pressure rise in inlet channel, when the pressure in inlet channel is greater than the default shrinkage value of elastic device, spring contraction, drive sealing-plug 1 separated with joint 4, open in water route, and current can enter in the intake tunnel that nozzle body 5 and joint 4 form, from fine mist spray head ejection, water mist system work.
Because water mist system boosts very soon, so said process is very short.When water mist system is closed, pump group is closed, in water route, pressure diminishes rapidly, when pressure is less than default close value, elastic device is upheld, and makes sealing-plug 1 continue to contact with the liquid flow hole 6 of pipe joint, plugging pipelines, thereby while preventing that pressure is too small, current spray from shower nozzle, prevent the generation of weeping.
Meanwhile, in the present embodiment, in pipe joint 4 and the junction of nozzle body 5, be provided with O type circle 3, the making material of O type circle 3 is rubber, has good compression ratio, by pipe joint 4 and the extruding of nozzle body 5, can play well sealing function.
In addition, in the present embodiment, liquid flow hole 6 is identical with the aperture of inlet opening 7, keeps the steady of current and pressure while making water source enter into fine mist spray head.In the inlet opening of the liquid flow hole of pipe joint inlet channel more than 6 part (along the inside pipe section of liquid flow hole 6) and nozzle body more than 7 partly (pipe section that Ji Yan inlet opening 7 is outside), the caliber of whole passage all diminishes gradually, makes current from become the current diameter suitable with shower nozzle size compared with Large Diameter Pipeline.Pipe joint outside is polygonal, convenient installation, and surface can be light face.
The improved fine mist spray head of the utility model; simple in structure, dependable performance; utilize hermetically-sealed construction realized when fine mist spray head is spurted with close after the shutoff of the water droplet that may occur; make installation process also become simple; improved the protection to water stain place of having relatively high expectations simultaneously, be conducive to thin water smoke and play a protective role better.This shower nozzle can be realized antidrip and reliability test well through test, can be effectively applied in engineering practice.
The above-mentioned description to embodiment is can understand and use the utility model for ease of those skilled in the art.Person skilled in the art obviously can easily make various modifications to these embodiment, and General Principle described herein is applied in other embodiment and needn't passes through performing creative labour.Therefore, the utility model is not limited to above-described embodiment, and those skilled in the art are according to announcement of the present utility model, and not departing from the improvement that the utility model category makes and revise all should be within protection domain of the present utility model.
