Description

Hand-buckled type spray head

Technical Field

The utility model relates to a shower nozzle technical field, in particular to formula shower nozzle is detained to hand.

Background

At present, a plurality of spray head products are sold in the market, a push type spray head product also has a hand buckling type spray head product, the push type spray head product has a shorter stroke, less water or spray amount and a larger stroke of the hand buckling type spray head product, and the water outlet amount is larger, so that the spray head product is popular with consumers. The hand-buckled type spray head is generally used for pumping liquid in a container out by buckling a wrench through fingers, an atomizer is generally arranged at an outlet for atomizing and spraying the liquid, and the hand-buckled type spray head can be used in the fields of flower growing, hairdressing shops, cosmetology and the like according to different components of the liquid in the container. The working principle is as follows: the piston moves in the pump body, so that gas in the pump body flows, the pressure intensity is reduced, the pressure intensity outside the pump body is unchanged, pressure intensity difference is generated inside and outside the pump body, and liquid is guided out of the pump body through the pressure intensity difference. The existing hand-buckled type spray head generally has the problem that a spring in a pump core can be contacted with liquid in the pump, the time is long, and the spring is easy to corrode and rust. Like chinese utility model patent CN201010221732.5, hand-clasping miniature atomizer improved generation structure and application method thereof, as shown in fig. 1, spring a sets up the sealed intracavity that the spring chamber of the pump body and the needle chamber of needle constitute, and liquid can contact with the spring by the in-process of being pumped, makes the spring rust easily, and the iron rust that the spring produced not only influences the quality of pumping liquid, still blocks up the shower nozzle easily.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a formula shower nozzle is detained to hand that can avoid liquid in the spring contact pump.

In order to solve the technical problem, the utility model discloses a following technical scheme, a formula shower nozzle is detained to hand, including connecting seat, pump head and spanner, the pump head is fixed on the connecting seat, and the spanner setting is on the pump head, its characterized in that: the spray head is characterized by further comprising a liquid outlet pipe, a spring seat, a spring, a gland, a pump body, a piston, a valve needle, a valve plate and a water inlet pipe, wherein the liquid outlet pipe is arranged in the pump head, the front end of the liquid outlet pipe is communicated with the spray head, the rear end of the liquid outlet pipe is communicated with the spring seat, one end of the spring is connected with the gland, the lower end of the spring; the piston and the valve needle are accommodated in the pump body, the gland blocks the upper end of the pump body, the lower part of the pump body is provided with a valve plate, and the lower end of the pump body is connected with a water inlet pipe.

The utility model discloses cup joint the spring on the spring holder, set up liquid channel in the spring holder, intercommunication pump body inner chamber. When the device is used, the wrench is pressed, the spring seat, the valve needle and the piston synchronously move downwards, the valve needle compresses the space of the liquid outlet pipe and the inner cavity of the spring seat, and extrusion liquid is sprayed out from the spray head. When the wrench is loosened, the spring seat rebounds under the action of the elastic force of the spring, and the liquid in the inner cavity of the pump body enters the inner cavity of the spring seat and the liquid outlet pipe under the action of the piston. The continuous liquid outlet or spraying can be realized by repeatedly pressing the wrench.

The utility model discloses cup joint the spring on the spring holder to be connected with the gland, the gland seals the spring holder lower extreme, makes liquid pass through the transmission of spring holder inner chamber, prevents that liquid from spilling over the spring holder outside, has avoided the direct contact of spring and liquid, can prevent effectively that the spring from rustting, has both guaranteed the quality of output liquid, has improved the life of shower nozzle again.

To sum up, the utility model discloses have and effectively avoid spring and liquid contact, prevent that the spring from rustting, long service life's beneficial effect.
