Description

A kind of shower nozzle

Technical field

The present invention relates to a kind of irrigation implement, especially a kind of shower nozzle.

Background technology

Existing watering dust prevention place like the irrigation in agricultural, gardens etc., needs the water spraying tool of use usually, is provided with the water outlet member in the shower nozzle of its water outlet, the break-make of control water-flowing path.

Existing shower nozzle comprises the copper core, and the copper in-core has water-flowing path, and an end of copper core and water delivery PE pipe is connected, other end one be provided with the copper pin, the outside is provided with nozzle.But utilize the path that forms opening and closing between copper pin and the nozzle; Make the current that come from water delivery PE pipe in use spray out through the path between copper pin and the nozzle through behind the water stream channel; And the path blockade between copper pin and the nozzle when need not to use can't spray.

Yet the structure of above-mentioned this shower nozzle, because copper core and copper pin are one, main parts all are made of copper, the cost of raw material is higher; And can't regulate the water yield of shower nozzle according to the needs of reality, use comparatively inconvenience.

Summary of the invention

Technical problem to be solved by this invention provides that a kind of cost is lower, the adjustable shower nozzle of water yield.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of shower nozzle; Comprise nozzle, it is characterized in that, also comprise the inner core that is inserted in the said nozzle; Said inner core comprises inner core main body and the integrated core head that is positioned at said inner core body front end; Have the cavity that the stream that supplies water passes through in the said inner core main body, have the gap between the madial wall of said interior core head and said nozzle, be provided with the through hole that is communicated with said cavity and gap in the said interior core head; Offer apopore on the front end face of said nozzle; Be equipped with the copper pin in the said apopore; Said copper pin comprise external diameter less than the copper pin main body of said apopore internal diameter and with the close-fitting copper needle section of said apopore, the rear end of said copper pin main body and said in core head fix.

Said inner core external side of main body wall is provided with external screw thread; Has internal thread on the relevant position of the madial wall of said nozzle; Make said inner core and nozzle realize threaded engagement, inner core can move relative to nozzle, the copper pin can with inner core backward side shifting seal apopore until the copper needle section; Or side shifting makes the current in gap when copper pin main body is positioned at apopore through the apopore ejection forward, and the discharge of ejection is directly proportional with distance between copper needle section and the apopore.

Have radially protuberance on the front end lateral wall of said inner core main body, the madial wall butt of said radially protuberance and said nozzle, said radially protuberance is provided with sealing ring, leaks from the gap of inner core main body and nozzle to avoid current.

Compared with prior art, the invention has the advantages that: inner core and copper pin are separately made, and inner core adopts plastics, has saved material, and processing technology is also comparatively simple; Threaded engagement through nozzle and inner core; Can pass through the relative position of rotation adjusting inner core and nozzle, thereby regulate the relative position of the apopore of copper pin and nozzle, with the sealing or the circulation flow path of fetching boiling water; And the distance of distance can also change the size of water yield, to satisfy the needs of various reality.

Description of drawings

Fig. 1 is the structural representation of shower nozzle of the present invention;

Fig. 2 is the cutaway view of shower nozzle of the present invention.

The specific embodiment

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.

Referring to Fig. 1 and Fig. 2, a kind of shower nozzle comprises nozzle 1 and inner core 2, and inner core 2 is made of plastics, and is inserted in the nozzle 1, and nozzle 1 rear inside wall has internal thread, and inner core 2 lateral walls have external screw thread, and nozzle 1 is fixed with inner core 2 threaded engagement thus.

Inner core 2 is made of plastics; Comprise inner core main body 21 and the integrated core head 22 that is positioned at inner core main body 21 front ends; Inner core main body 21 is hollow form, has cavity 211 in it, and external screw thread 212 is positioned on the lateral wall of inner core main body 21; Have internal thread 11 on the relevant position of the madial wall of nozzle 1, thereby inner core 2 is realized threaded engagement with nozzle 1; Have radially protuberance 213 on the front end lateral wall of inner core main body 21, with the madial wall butt of nozzle 1, radially protuberance 213 is provided with sealing ring 214, leaks to avoid current.

The external diameter of interior core head 22 is less than the external diameter of inner core main body 21; Has gap 221 between the madial wall of itself and nozzle 1; Offer the through hole 222 that is communicated with the cavity 211 of inner core main body 21 in the interior core head 22, through hole 222 is communicated with gap 221 that (Fig. 2 is owing to the not shown connected state of the reason of analysing and observe direction, on the cutaway view herein; Through hole 222 is communicated with the direction that gap 221 should be at vertical paper), current can enter in the gap 221 through behind the through hole 222 from cavity 211.

Offer apopore 13 on the front end face 12 of nozzle 1; Rear end and interior core head 22 fixing copper pins 3 are located in the apopore 13; Copper pin 3 comprises copper pin main body 31 and copper needle section 32; The rear end of copper pin main body 31 and interior core head 22 are fixing, and its external diameter is less than the internal diameter of apopore 13, and the internal diameter of the external diameter of copper needle section 32 and apopore 13 matees.

In the time of need not spraying water, copper needle section 32 is positioned at apopore 13, and both closely cooperate, and thus, water can't be from apopore 13 ejections in the gap 221; When needs are sprayed water, rotate inner core 2, regulate the relative position of nozzle 1 and inner core 2; Make copper pin 3 side shifting forward, copper needle section 32 is left apopore 13, because the external diameter of copper pin main body 31 is less than the internal diameter of apopore 13; Therefore, current can be from ejection between copper pin main body 31 and the apopore 13.Through rotation inner core 2, regulate the distance between copper needle section 32 and the apopore 13, can adjust the size of the water surface, thereby adjust the size of the water yield, more greatly then water yield is big more for distance, and the more little then water yield of distance is more little, to satisfy actual demand.

The above is merely preferred implementation of the present invention, should be pointed out that for those of ordinary skill in the art, not breaking away under the principle prerequisite of the present invention, can also make various deformation and improvement, and this also should be regarded as protection scope of the present invention.
