Description

A kind of shower nozzle

Technical field

The utility model relates to a kind of irrigation implement, especially a kind of shower nozzle.

Background technology

Existing watering dust prevention place such as 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, so that the current that come from water delivery PE pipe in use spray out by 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 integrated, main parts all are made of copper, the cost of raw material is higher; And can't regulate according to the actual needs the water yield of shower nozzle, use comparatively inconvenience.

The utility model content

Technical problem to be solved in the utility model provides that a kind of cost is lower, the adjustable shower nozzle of water yield.

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

The lateral wall of described inner core main body is provided with external screw thread, has internal thread on the relevant position of the madial wall of described nozzle, so that described inner core and nozzle are realized threaded engagement, inner core can move relative to nozzle, the copper pin can with inner core backward side shifting until copper needle section sealing apopore, or forward side shifting so that copper pin main body when being positioned at apopore the current in gap spray by apopore, 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 described inner core main body, the madial wall butt of described radially protuberance and described nozzle, described 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 utility model has the advantage of: 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 by nozzle and inner core, can regulate by rotation the relative position of inner core and nozzle, thereby regulate the relative position of the apopore of copper pin and nozzle, with 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 utility model;

Fig. 2 is the cutaway view of shower nozzle of the present utility model.

The specific embodiment

Embodiment is described in further detail the utility model 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 and inner core 2 threaded engagement are fixed 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, 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 and nozzle 1 are realized threaded engagement; 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, the copper pin 3 that rear end and interior core head 22 are fixed is 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, 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 mates.

When not needing to spray water, copper needle section 32 is positioned at apopore 13, and both closely cooperate, and thus, gap 221 interior water can't be from apopore 13 ejections; When needs are sprayed water, rotate inner core 2, regulate the relative position of nozzle 1 and inner core 2, so that 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.By rotary inner core 2, regulate the distance between copper needle section 32 and the apopore 13, can adjust the size of the water surface, thus the size of water yield adjusting, the larger then water yield of distance is larger, and the less then water yield of distance is less, to satisfy actual demand.

The above only is preferred embodiment of the present utility model; should be pointed out that for the ordinary skill in the art, do not breaking away under the principle prerequisite of the present utility model; can also make various deformation and improvement, this also should be considered as protection domain of the present utility model.
