Description

Technical fields:

[0001] This utility model belongs to the field of nozzle technology, and specifically refers to an atomizing nozzle. Background technology:

[0002] Pressure atomizing nozzles mostly spray liquids through tiny orifices under high pressure, breaking them into fine droplets by their own kinetic energy, thereby increasing the contact area between the liquid and air or other media and improving evaporation efficiency.

[0003] However, existing atomizing nozzles are prone to clogging in applications with hard water or high levels of impurities, leading to atomization failure or even complete water output. This is because the tiny atomization channels or apertures are easily clogged by suspended solids, mineral deposits, and other particulate matter in the water, requiring frequent maintenance or replacement. Summary of the Invention:

[0004] The purpose of this invention is to provide an atomizing nozzle that can automatically adjust the size of the atomization gap according to changes in hydraulic pressure, effectively solving the problem of atomization failure due to clogging.

[0005] This utility model is implemented as follows:

[0006] An atomizing nozzle includes a nozzle body with an inner cavity. A valve stem moves axially within the inner cavity of the nozzle body. A separating valve diaphragm is provided between the valve stem and the inner cavity sidewall of the nozzle body. The separating valve diaphragm divides the inner cavity of the nozzle body into a hydraulic chamber and a preload chamber. The axially moving valve stem causes the inner ring of the separating valve diaphragm to undergo elastic deformation. A preload spring is provided between the preload chamber and the corresponding end of the valve stem. The nozzle body has a water inlet hole communicating with the hydraulic chamber and an atomizing nozzle hole opposite to the upper end of the valve stem. An atomizing gap is formed between the upper end of the valve stem and the atomizing nozzle hole, and the valve stem can completely block the inner port of the atomizing nozzle hole.

[0007] In the aforementioned atomizing nozzle, the inner port of the atomizing nozzle has an inner conical surface structure that is larger inside and smaller outside, and the upper end of the valve stem has an outer conical surface structure that can cooperate with the inner conical surface structure of the atomizing nozzle.

[0008] In the aforementioned atomizing nozzle, the nozzle body includes an upper sleeve with a lower port and a lower sleeve with an upper port. The lower port of the upper sleeve and the upper port of the lower sleeve are connected and fixed vertically. The outer ring of the separating valve membrane is clamped and fixed between the lower end face of the upper sleeve and the upper end face of the lower sleeve, and the inner ring of the separating valve membrane is sleeved on the valve stem.

[0009] In the aforementioned atomizing nozzle, a connecting flared groove is provided at the lower end of the upper sleeve, and the upper end of the lower sleeve is threadedly connected to the connecting flared groove. A clamping gap for clamping the outer ring of the separator valve membrane is formed between the upper end face of the lower sleeve and the bottom surface of the connecting flared groove.

[0010] In the aforementioned atomizing nozzle, an annular protrusion is provided on the outer wall of the valve stem. A clamping seat and a pre-tightening nut are sleeved on the valve stem located on the upper side of the annular protrusion. A clamping gap is formed between the clamping seat and the annular protrusion for clamping the inner ring of the separating valve membrane. The pre-tightening nut is threaded onto the valve stem, and the pre-tightening nut is screwed downward to push the clamping seat down onto the inner ring of the separating valve membrane.

[0011] In the aforementioned atomizing nozzle, the upper end of the preload spring abuts against the lower end face of the annular protrusion, and the lower end abuts against the preload nut, which is threadedly connected to the preload cavity.

[0012] The outstanding advantages of this utility model compared to the prior art are:

[0013] This utility model has a simple structure, reasonable design, and low cost. It uses the elastic force of a preloaded spring to push the valve stem upward to completely block the atomizing nozzle. The hydraulic pressure in the hydraulic chamber pushes the separator diaphragm, causing the valve stem to move downward. This creates a small atomizing gap between the upper end of the valve stem and the atomizing channel. Furthermore, it can automatically adjust the size of the atomizing gap according to changes in hydraulic pressure. That is, when particulate matter blocks the atomizing gap, the hydraulic pressure in the hydraulic chamber increases and drives the valve stem downward through the separator diaphragm, thus increasing the atomizing gap. This effectively solves the problem of atomization failure due to blockage. Attached image description:

[0016] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 :

[0017] Atomizing nozzle includes a nozzle body with an inner cavity. A valve stem 1 moves axially within the inner cavity of the nozzle body. A separating valve diaphragm 2 is provided between the valve stem 1 and the inner cavity sidewall of the nozzle body. The separating valve diaphragm 2 divides the inner cavity of the nozzle body into a hydraulic chamber 3 and a preload chamber 4. The axially moving valve stem 1 causes the inner ring of the separating valve diaphragm 2 to undergo elastic deformation. A preload spring 5 is provided between the preload chamber 4 and the corresponding end of the valve stem 1. The nozzle body has a water inlet hole 6 communicating with the hydraulic chamber 3 and an atomizing nozzle 7 opposite to the upper end of the valve stem 1. An atomizing gap is formed between the upper end of the valve stem 1 and the atomizing nozzle 7, and the valve stem 1 can completely block the inner port of the atomizing nozzle 7.

[0018] This utility model has a simple structure, reasonable design, and low cost. It uses the elastic force of the preloaded spring 5 to push the valve stem 1 upward to completely block the atomizing nozzle 7. The hydraulic pressure in the hydraulic chamber 3 pushes the separator diaphragm 2, which in turn drives the valve stem 1 downward. This creates a small atomizing gap between the upper end of the valve stem 1 and the atomizing channel. Furthermore, it can automatically adjust the size of the atomizing gap according to changes in hydraulic pressure. That is, when particulate matter blocks the atomizing gap, the hydraulic pressure in the hydraulic chamber 3 increases and drives the valve stem 1 downward through the separator diaphragm 2, thus increasing the atomizing gap and effectively solving the problem of atomization failure due to blockage.

[0019] Furthermore, in order to increase the contact area between the valve stem 1 and the atomizing nozzle 7, the inner port of the atomizing nozzle 7 has an inner conical surface structure that is larger inside and smaller outside, and the upper end of the valve stem 1 has an outer conical surface structure that can cooperate with the inner conical surface structure of the atomizing nozzle 7.

[0020] In this embodiment, the specific structure of the nozzle body and the specific fixing structure of the separator diaphragm 2 in the inner cavity of the nozzle body are as follows: the nozzle body includes an upper sleeve 8 with a lower port and a lower sleeve 9 with an upper port. The lower port of the upper sleeve 8 and the upper port of the lower sleeve 9 are connected and fixed vertically. The outer ring of the separator diaphragm 2 is clamped and fixed between the lower end face of the upper sleeve 8 and the upper end face of the lower sleeve 9. The inner ring of the separator diaphragm 2 is sleeved on the valve stem 1.

[0021] The upper sleeve 8 and the lower sleeve 9 can be fixed by a plunger or by a snap-fit. In this embodiment, the lower end of the upper sleeve 8 is provided with a connecting flared groove 10, and the upper end of the lower sleeve 9 is threaded to the connecting flared groove 10. A clamping gap is formed between the upper end face of the lower sleeve 9 and the bottom surface of the connecting flared groove 10 for clamping the outer ring of the separator valve diaphragm 2.

[0022] In order to ensure that the separator diaphragm 2 can be securely connected to the valve stem 1, an annular protrusion 11 is provided on the outer wall of the valve stem 1. A clamping seat 12 and a pre-tightening nut 13 are sleeved on the valve stem 1 located on the upper side of the annular protrusion 11. A clamping gap is formed between the clamping seat 12 and the annular protrusion 11 for clamping the inner ring of the separator diaphragm 2. The pre-tightening nut 13 is threadedly connected to the valve stem 1, and the pre-tightening nut 13 is screwed downward to push the clamping seat 12 down to press on the inner ring of the separator diaphragm 2.

[0023] Furthermore, the upper end of the preload spring 5 abuts against the lower end face of the annular protrusion 11, and the lower end abuts against the preload nut 14, which is threadedly connected to the preload cavity 4.

[0024] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
