Abstract
Description
Technical Field
[0001] This utility model relates to the field of nozzle technology, specifically to an anti-drip nozzle controlled by an electromagnetic valve. Background Technology
[0002] With increasing awareness of water conservation and rising demands for environmental performance, the market urgently needs a sprinkler head that can effectively prevent dripping. This type of sprinkler head must not only possess the rapid response and precise control capabilities of solenoid valves, but also solve the problem of dripping after traditional sprinklers are turned off, thereby improving water resource utilization efficiency, enhancing the user experience, and meeting the needs of various fields.
[0003] Solenoid valves control the opening and closing of the valve using electromagnetic force, enabling rapid response to control signals and instantaneous opening and closing of water flow. However, existing solenoid valves controlling sprinklers still struggle to completely prevent dripping when closed due to the internal structure of the solenoid valve and water flow characteristics. For example, even after the solenoid valve is closed, a certain amount of water may remain inside the sprinkler head, which will continue to drip under gravity. Utility Model Content
[0004] The purpose of this invention is to provide a solenoid valve-controlled anti-drip nozzle that has the advantage of preventing nozzle dripping and solves the problem that current solenoid valve-controlled nozzles still cannot completely prevent dripping when closed.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a solenoid valve-controlled anti-drip spray head, comprising a spray head mechanism, wherein a spray head assembly is provided at one end of the spray head mechanism and a solenoid valve body is provided at the other end, and a drive mechanism connected to the spray head mechanism is provided inside the solenoid valve body, the spray head mechanism comprising a housing, two connecting pipes being staggered on both sides of the housing, a first through hole being provided at the end of the housing away from the solenoid valve body, and a connecting member being spirally connected thereto, a second through hole being provided inside the connecting member communicating with the first through hole, and a plurality of grooves being provided in a ring array equidistantly around the connecting member.
[0006] Preferably, the nozzle assembly includes a first circular tube, with a sealing ring fitted at one end of the first circular tube facing the housing, and a circular plate at the other end. A limit ring is provided on the side of the circular plate away from the first circular tube, and a spray pipe is provided on the side of the circular plate with the limit ring.
[0007] Preferably, a short pipe is provided in the middle of the side of the circular plate facing the nozzle, and six third through holes are equally spaced in a ring array around its axis inside the circular plate.
[0008] Preferably, one end of the nozzle facing the first circular tube is provided with a limiting tube that is sleeved on the outer edge of the limiting ring, and the other end is spherical with a transverse groove. The outer edge of the nozzle is provided with a nut that covers the first circular tube and is spirally connected to the connector.
[0009] Preferably, the driving mechanism includes a long tube, one end of which is provided with a connector that spirally extends into the housing, and a blind groove is opened in the long tube, and a valve core is slidably installed therein, the valve core having a blind groove and a spring being fitted inside.
[0010] Preferably, the length of the valve core is less than the depth of the blind groove inside the long tube, and the length of the spring is greater than the depth of the blind groove inside the valve core.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This invention utilizes a first circular pipe, a circular plate, a third through hole, a limiting ring, a nozzle, a limiting tube, and a transverse groove. Water is transported through the first circular pipe, and the flow rate is increased by passing through a short pipe with a decreasing diameter. The water is then sprayed out through the transverse groove at the end of the nozzle, forming a fan-shaped water curtain. Several limiting rings, positioned on the circular plate, are embedded within the limiting tube, creating a water flow channel that allows for smoother water flow within the nozzle, reducing water residue and accumulation, thus minimizing the possibility of dripping. When the solenoid valve is closed, the water flow stops quickly, preventing water accumulation inside the nozzle and achieving the effect of preventing dripping. Attached Figure Description
