Abstract
The invention discloses a nozzle structure relating to a nozzle. The invention provides a nozzle structure mainly used for bathroom accessory shower heads, and utilizes the self-excitation oscillation of current to produce a pulsant current beam. The nozzle structure is provided with a nozzle body which is provided with a cavity, the front end of the cavity is communicated with a nozzle water inlet via a path, and the rear end of the cavity is communicated with the nozzle water outlet via the path; an insulator is arranged in the cavity and is composed of a front flow guidance post and a reattaching flow afterbody, wherein the front flow guidance post is arranged in the front part of the cavity, and the reattaching flow afterbody is arranged in the rear part of the cavity; a gap is arranged between the front flow guidance post and the reattaching flow afterbody; and a front cavity is formed between the front flow guidance post and the front path water outlet, and a rear cavity is formed between the reattaching flow afterbody and the rear path water inlet.
Description
Technical field
The present invention relates to a kind of nozzle, especially relate to a kind of nozzle arrangements that is mainly used in the bathroom gondola water faucet.
Background technology
Massage type gondola water faucet nozzle has special structure, when current pass through, can form a fluid stream of certain orientation, speed and certain cyclic process, thereby play massage effect.At present, have some products both at home and abroad, it is functional, but complex structure, generally, domestic massage type structure of nozzle form, all be to rotate and hide ostium excurrens by the current driven vane to produce pulse, that is to say, need wheel rotor or complicated textural association, could realize that nozzle goes out the pulsation effect of current, and pulsatile effect not very desirable.To the more existing reports of massaging shower product and function, the assembly of the massaging shower that domestic patent relates to and structure, existing gondola water faucet generally adopts the massage type nozzle, plays massage effect.But do not see the pulsating quantity that design utilizes fluid to produce,, excite self-excitation to shake to produce the pertinent literature and the patent of the gondola water faucet or the flagship product of pulsed massage spray by cavity and passage.
Chinese patent CN1681601 discloses a kind of shower nozzle, to be formed with the maintaining part (1a) on the water flowing road that is communicated in the hot and cold water inflow entrance in inside and be provided with the water portion of spreading (1b) of a plurality of limbers, the open and close valve (6) that Jie is equipped on this maintaining part (1a) freely or spreads the end of water portion (1b) with loading and unloading connects and constitutes nozzle body (1c), and the button (12) of the on-off action of implementing above-mentioned open and close valve is installed freely in above-mentioned the other end loading and unloading of spreading water portion (1a).
Chinese patent CN2397871 discloses a kind of pin type shower nozzle, and the spherical oscillating nozzle that will have various different angles pin holes is contained in an end of spring.
Summary of the invention
The object of the present invention is to provide a kind of nozzle arrangements that is mainly used in the bathroom gondola water faucet, it utilizes the self-oscillation of current and produces the water stream that of pulsation.
The present invention is provided with nozzle mouth body, be provided with cavity in the mouth body, the front end of cavity is communicated with the nozzle water inlet through prepass, the rear end of cavity through after passage be communicated with the nozzle delivery port, spacer is set in cavity, and spacer is made up of the preceding diversion column of being located at the cavity front portion and the attached stream back body of being located at the cavity rear portion, is provided with the slit between preceding diversion column and the attached stream back body, cavity before forming between preceding diversion column and the prepass delivery port, cavity after forming between body and the back passage water inlet behind the attached stream.
Diversion column can be made as half round post before described.
Described attached stream back body can be made as half round post.
Key technology of the present invention is, the pulsating quantity of utilizing fluid when flowing through the interruption solid boundaries, to produce, and by designing suitable cavity and passage, the self-oscillation that inspires fluid produces the pulsed massage spray.Preceding diversion column can be half-cylindrical, or any bluff body that connects spacing that can form betwixt, and such as the triangle cylindricality, body is half-cylindrical behind the attached stream.When current stream by the time because the self-oscillation of inner fluid passage produces fluctuating flow in the wake zone of attached stream back body, cause forming the fluctuating flow of certain orientation, thereby play the massage effect in the shower process at jet expansion.This shows that than massage type nozzle both domestic and external, the present invention utilizes current self-oscillation principle, reaches optimization, simplification and improvement on the massage type nozzle arrangements, structure is more succinct.
Description of drawings
Fig. 1 is that the structure of the embodiment of the invention is formed schematic diagram.
The specific embodiment
Referring to Fig. 1, the present invention is provided with nozzle mouth body 1, be provided with cavity in the mouth body 1, the front end of cavity is communicated with nozzle water inlet 11 through prepass 2, the rear end of cavity through after passage 3 be communicated with nozzle delivery port 12, spacer is set in cavity, spacer is made up of preceding diversion column A that is located at the cavity front portion and the attached stream back body B that is located at the cavity rear portion, be provided with slit S between preceding diversion column A and the attached stream back body B, cavity C before forming between preceding diversion column A and the prepass delivery port 13, cavity D after forming between body B and the back passage water inlet 14 behind the attached stream.Diversion column A is made as half round post before described, and described attached stream back body B is made as half round post.
Claims (3)
1. nozzle arrangements, it is characterized in that being provided with nozzle mouth body, be provided with cavity in the mouth body, the front end of cavity is communicated with the nozzle water inlet through prepass, the rear end of cavity through after passage be communicated with the nozzle delivery port, spacer is set in cavity, spacer is made up of the preceding diversion column of being located at the cavity front portion and the attached stream back body of being located at the cavity rear portion, be provided with the slit between preceding diversion column and the attached stream back body, cavity before forming between preceding diversion column and the prepass delivery port, cavity after forming between body and the back passage water inlet behind the attached stream.
