Description

Technical Field

[0001] This utility model relates to the field of atomizers, and more particularly to an atomizer for ICP-OES testing. Background Technology

[0002] A nebulizer is a device that transforms liquids into tiny droplets (aerosols). It disperses solutions such as medications and essential oils into micron-sized particles through physical or mechanical means (such as ultrasound, compressed gas, or piezoelectric effect), making them easy to inhale or spray. It is widely used in medical (e.g., nebulized inhalation therapy for asthma and COPD), industrial (humidification, spraying), and home (air humidification, aromatherapy) fields. Its core features include improved liquid absorption efficiency or uniform coverage, ease of operation, and suitability for various scenarios.

[0003] A search revealed patent publication number CN211132526U, which discloses an atomizer comprising: an atomizer body equipped with an atomizing device; an atomizer connector on the surface of the atomizer body, the end of which is a female connector; an atomizing cup connected to the atomizer connector via an atomizing tube, the end of which is equipped with an atomizing tube connector adapted to the atomizer connector; and the inner diameter of the root of the atomizer connector tapering in a stepped manner. In this atomizer, the atomizing tube connector is a male connector with a certain degree of elasticity, and the atomizer connector is a female connector. Under the action of airflow, the atomizing tube connector deforms against the inner wall surface of the atomizer, increasing the pressure between the two and thus increasing friction to prevent loosening. An annular sealing ring on the surface of the atomizing tube connector maintains a seal between the atomizing tube connector and the atomizer connector. Simultaneously, the sealing ring is engaged in a groove within the atomizer connector, further preventing the atomizing tube connector from loosening.

[0004] While existing technologies can achieve a certain atomization effect and enable detection after atomization, they have drawbacks: after prolonged use, existing atomizers tend to accumulate multiple layers of material at the nozzle, leading to inconvenience in maintenance and affecting overall performance. In view of this, we propose an atomizer for ICP-OES testing that solves the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an atomizer for ICP-OES detection.

[0006] The technical solution of this utility model is as follows: an atomizer for ICP-OES testing, comprising a housing, a booster, a control valve one, a control valve two, a nozzle, and a movable head. The booster is fixed at the lower end of the housing, the control valve one is embedded in the upper end of the housing, the control valve two is provided on one side of the control valve one, the nozzle is rotatably mounted on one side of the housing, and a movable head is rotatably mounted on one end of the nozzle.

[0007] When using this device, the main water inlet pipe can be connected to inlet one, and the auxiliary water inlet pipe can be connected to inlet two. With the help of the booster, liquid can be sprayed from the nozzle. The pressure sensor will detect the pressure in the internal cavity of the housing. When the pressure is lower than the set value, the controller will activate control valve two to replenish the liquid, so that the appropriate pressure can be matched with the appropriate flow rate for spraying. The guide surface of the nozzle design can reduce liquid residue. After long-term use, the movable head will accumulate gel-like material, which can easily cause nozzle blockage. Therefore, the movable head can be rotated for replacement. This device can realize convenient replacement of the atomizing head and stabilize the spray of atomizing agent, which can prevent the problem of nozzle blockage after long-term use and has high practicality.

[0008] Preferably, a pressure sensor is embedded in the middle of the upper end of the housing, and a controller is provided on one side of the pressure sensor. The cooperation between the pressure sensor and the controller enables real-time pressure monitoring and automatic liquid replenishment, ensuring that the system pressure is always in the optimal state and improving the stability of the atomization effect.

[0009] Preferably, the supercharger has an intake pipe on one side and a pipe connecting the other side of the supercharger to the housing. The pipe connection design between the supercharger and the intake pipe and the housing optimizes the gas flow path, enhances the boosting efficiency, simplifies the structure, and reduces energy consumption.

[0010] Preferably, the upper end of the first control valve is fixed with a first water inlet, and the upper end of the second control valve is fixed with a second water inlet. The first control valve and the second control valve are connected to an external pipeline, and the dual-inlet design with the first water inlet and the second control valve supports flexible switching and replenishment of the main and auxiliary pipelines, adapts to different working conditions, and improves the applicability of the equipment.

[0011] Preferably, the nozzle has a conical design, with a guide surface on the inner wall of the top of the nozzle and a threaded groove on one side of the guide surface. The conical nozzle combined with the guide surface reduces turbulence and liquid adhesion, and the threaded groove facilitates quick installation of the movable head, further reducing maintenance difficulty.

[0012] Preferably, the movable head has a threaded wire on one side, which engages with a threaded groove. The inner wall of the movable head has an internal thread arranged in a ring array. The engagement structure of the threaded wire and the threaded groove ensures a stable connection of the movable head. The ring-shaped internal thread design enhances atomization uniformity and improves spray accuracy. The quick replacement of the movable head facilitates rapid maintenance after clogging and ensures good output performance.

[0013] Preferably, a double-layer sealing ring is fixed on one side of the movable head. The double-layer sealing ring effectively prevents liquid leakage, takes into account both sealing performance and wear resistance, and reduces the need for frequent replacement due to wear.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model ensures stable liquid injection pressure and avoids flow fluctuations through the coordinated operation of the booster and control valve; the replaceable design of the movable head effectively solves the clogging problem caused by the accumulation of gel-like substances and extends the service life of the equipment; the guide surface design of the nozzle reduces liquid residue and improves injection efficiency.

[0016] II. Based on the first beneficial effect, this device significantly improves the stability and reliability of atomization spray through modular design (such as replaceable movable heads and split control valves) and intelligent control (pressure sensing and automatic liquid replenishment). Its structural optimization (guide surface, threaded connection, sealing ring) solves common problems such as residue, blockage, and leakage, combining high efficiency and long lifespan, making it suitable for medical scenarios with stringent requirements for atomization quality.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
