Description

Technical Field

[0001] This utility model belongs to the field of liquid atomization technology, and more specifically, it relates to an atomizing nozzle for an oxygen humidifier. Background Technology

[0002] The oxygen humidifier connects to the oxygen terminal and can be connected to various types of plugs according to different requirements. It is used by medical units for emergency oxygen administration and oxygen inhalation for hypoxic patients. The oxygen inhaler has a precise flow rate and is convenient and safe to use. It is an essential piece of equipment for hospital emergency rooms, wards and patient oxygen therapy.

[0003] After passing through an oxygen humidification bottle, the oxygen is delivered into the patient's mouth along with the atomized medication, providing both oxygen and some therapeutic effects. However, in current technology, the high-speed spray of the atomized medication from the oxygen humidification bottle directly affects the patient's mouth, potentially causing irritation and discomfort in the oral cavity or throat. Utility Model Content

[0004] The purpose of this invention is to provide an oxygen humidifier atomizing nozzle, which aims to solve the problem that the high-speed spraying of atomized medicine directly onto the patient's mouth can cause irritation and discomfort in the patient's mouth or throat.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An oxygen humidifier atomizing nozzle is provided, comprising a main body, a mist outlet pipe at the top of the main body, a jet pipe extending through the bottom of the main body, a liquid inlet pipe connected to the lower end of the jet pipe, a spray outlet at the upper end of the jet pipe, an atomizing sleeve within the inner cavity of the main body, the atomizing sleeve being fitted over the upper part of the jet pipe, an atomizing plate at the top of the atomizing sleeve, and a downwardly protruding arc-shaped atomizing surface in the middle of the atomizing plate. The arc-shaped atomizing surface is located directly above the spray outlet. Liquid ejected from the spray outlet impacts the arc-shaped atomizing surface, forming a circumferentially diffused atomized liquid that is then discharged from the mist outlet pipe after being deflected.

[0006] In one possible implementation, an end cap is threaded onto the top of the main body, and the mist outlet is located at the center of the upper end face of the end cap.

[0007] In one possible implementation, a tapered sleeve is provided at the bottom of the main tube, the diameter of the tapered sleeve decreasing from top to bottom, an installation hole is provided at the bottom of the tapered sleeve, an installation sleeve is provided in the middle of the inner cavity of the tapered sleeve, the lower end of the installation sleeve is connected to the installation hole, and the spray pipe passes through the installation sleeve from bottom to top and extends into the inner cavity of the main tube.

[0008] In one possible implementation, a baffle is provided circumferentially at the lower part of the injection pipe, the baffle abuts against the bottom of the tapered sleeve and is located on the outer periphery of the mounting hole, and the liquid inlet pipe is sleeved on the lower end of the injection pipe and located below the baffle.

[0009] In one possible implementation, the lower end of the main tube is provided with a skirt, which surrounds the outer periphery of the tapered sleeve.

[0010] In one possible implementation, the tapered sleeve, the skirt, and the main body are integrally formed.

[0011] In one possible implementation, the upper end of the injection pipe has a tapered end, the inner diameter of which decreases from bottom to top, and the nozzle is located at the top of the inner cavity of the tapered end.

[0012] In one possible implementation, the upper end of the atomizing sleeve is provided with a conformal conical tube, which is sleeved from top to bottom outside the conical end. Connecting portions are provided on both sides of the conformal conical tube, and the two connecting portions extend upward to above the nozzle. The atomizing plate is connected to the upper ends of the two connecting portions.

[0013] In one possible implementation, the distance between the nozzle and the arc-shaped atomizing surface is 0.5 mm to 1 mm.

[0014] In one possible implementation, the main body is made of a transparent material, and scale markings are provided on the side wall of the main body from top to bottom.

[0015] The beneficial effects of the oxygen humidifier nebulizer nozzle provided by this utility model are as follows: Compared with the prior art, the oxygen-mixed liquid enters the injection pipe through the inlet pipe, and is sprayed upward through the nozzle at the upper end of the injection pipe. The high-speed liquid impacts the arc-shaped atomizing surface in the middle of the atomizing plate, thereby forming a circumferentially diffused atomized liquid. After being deflected, the atomized liquid is discharged upward through the mist outlet pipe and acts on the patient's oral cavity. The oxygen humidifier nebulizer nozzle provided by this utility model can form an oxygen-mixed atomized liquid. The atomized liquid is buffered by deflection inside the main body, thereby reducing the spray speed of the atomized liquid into the patient's oral cavity, reducing irritation to the patient's oral cavity, and improving the patient's comfort.

It does not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific protection scope of this utility model.

[0026] Please see Figures 1 to 4The oxygen humidifier atomizing nozzle provided by this utility model will now be described. The oxygen humidifier atomizing nozzle includes a main body 1, with a mist outlet pipe 2 at the top of the main body 1 and a jet pipe 3 penetrating through the bottom of the main body 1. The lower end of the jet pipe 3 is connected to a liquid inlet pipe 4, and the upper end of the jet pipe 3 has a spray outlet 5. An atomizing sleeve 6 is provided in the inner cavity of the main body 1 and is fitted onto the upper part of the jet pipe 3. An atomizing plate 7 is provided at the top of the atomizing sleeve 6, and a downwardly protruding arc-shaped atomizing surface 8 is provided in the middle of the atomizing plate 7. The arc-shaped atomizing surface 8 is located directly above the spray outlet 5. The liquid sprayed from the spray outlet 5 impacts the arc-shaped atomizing surface 8, forming an atomized liquid that diffuses circumferentially and is discharged from the mist outlet pipe 2 after being deflected.

[0027] Compared with the prior art, the oxygen humidifier nebulizer nozzle provided by this utility model has an oxygen-mixed liquid medication entering the injection pipe 3 through the inlet pipe 4. The oxygen-mixed liquid medication is then sprayed upward through the nozzle 5 at the upper end of the injection pipe 3. The high-speed liquid sprayed out impacts the arc-shaped atomizing surface 8 in the middle of the atomizing plate 7, thereby forming a circumferentially diffused atomized liquid medication. After being deflected, the atomized liquid medication is discharged upward through the mist outlet pipe 2 and acts on the patient's oral cavity. The oxygen humidifier nebulizer nozzle provided by this utility model can form an oxygen-mixed atomized liquid medication. The atomized liquid medication is deflected and buffered inside the main pipe body 1, thereby reducing the spray speed of the atomized liquid medication into the patient's oral cavity, reducing irritation to the patient's oral cavity, and improving the patient's comfort.

[0028] In some embodiments, please refer to Figure 2 An end cap 9 is threaded onto the top of the main body 1, and the mist outlet pipe 2 is located in the middle of the upper end face of the end cap 9. The end cap 9 is threaded onto the top of the main body 1, which facilitates the disassembly and maintenance of the mist outlet pipe 2 and also provides a channel for the installation of the atomizing sleeve 6 into the main body 1.

[0029] Please see Figure 2 The bottom of the main pipe body 1 is provided with a tapered sleeve 10, the diameter of which decreases from top to bottom, which increases the axial length of the inner cavity of the main pipe body 1 and facilitates the installation of the spray pipe 3. The bottom of the tapered sleeve 10 is provided with an installation hole, and an installation sleeve 11 is provided in the middle of the inner cavity of the tapered sleeve 10. The lower end of the installation sleeve 11 is integrally formed and connected to the installation hole. The spray pipe 3 passes through the installation sleeve 11 from bottom to top and extends into the inner cavity of the main pipe body 1. The spray pipe 3 and the installation sleeve 11 are tightly fitted to ensure the stability of the installation of the spray pipe 3.

[0030] The lower part of the injection pipe 3 is circumferentially equipped with a baffle 12. The baffle 12 abuts against the bottom of the tapered sleeve 10 and is located on the outer periphery of the mounting hole. The baffle 12 can limit the distance that the injection pipe 3 is inserted into the mounting sleeve 11, ensuring that the nozzle 5 at the upper end of the injection pipe 3 is at a suitable height within the inner cavity of the main body 1. The liquid inlet pipe 4 is sleeved on the lower end of the injection pipe 3 and is located below the baffle 12. The baffle 12 can also limit the distance that the liquid inlet pipe 4 is sleeved on the lower end of the injection pipe 3. The upper end of the liquid inlet pipe 4 abuts against the lower end face of the baffle 12, which can ensure a stable connection between the liquid inlet pipe 4 and the injection pipe 3 while also improving the sealing performance of the liquid inlet pipe 4.

[0031] The lower end of the main body 1 is provided with a skirt 13. The skirt 13 surrounds the outer periphery of the conical sleeve 10, which can provide a certain degree of protection for the liquid inlet pipe 4 and the spray pipe 3. At the same time, the skirt 13 can also improve the aesthetics of the atomizing nozzle and make it easier for the operator to hold the atomizing nozzle.

[0032] Specifically, the tapered sleeve 10, the skirt 13, and the main body 1 are integrally formed.

[0033] Please see Figure 2 and Figure 3 The upper end of the injection pipe 3 has a tapered end 14, the inner diameter of which decreases from bottom to top, and the nozzle 5 is located at the top of the inner cavity of the tapered end 14. The tapered end 14 can concentrate the oxygen-mixed liquid to the nozzle 5, so that the liquid is ejected from the nozzle 5 at high speed.

[0034] Please see Figure 2 and Figure 3 The upper end of the atomizing sleeve 6 is provided with a conformal conical tube 15, which is fitted from top to bottom onto the outside of the conical end 14. The conformal conical tube 15 combines a certain degree of elasticity and strength. When the conformal conical tube 15 is fitted onto the conical end 14, the lower part of the atomizing sleeve 6 is also fitted onto the outside of the spray pipe 3, so that the atomizing sleeve 6 is stably installed on the spray pipe 3. Connecting parts 16 are provided on both sides of the conformal conical tube 15, and the two connecting parts 16 extend upward to the top of the spray outlet 5. The atomizing plate 7 is connected to the upper end of the two connecting parts 16. The two connecting parts 16 are integrally formed and symmetrically arranged on both sides of the atomizing sleeve 6. The atomizing plate 7 is horizontally integrally formed on the upper end of the two connecting parts 16. The arc-shaped atomizing surface 8 in the middle of the lower end face of the atomizing plate 7 faces the spray outlet 5, so that the high-speed sprayed liquid directly impacts the arc-shaped atomizing surface 8 to form atomized liquid that diffuses in a circumferential direction.

[0035] Specifically, the distance between the nozzle 5 and the arc-shaped atomizing surface 8 is 0.5mm-1mm.

[0036] Preferably, the main tube 1 is made of a transparent material, such as PS plastic or ABS plastic, to facilitate medical personnel in observing the atomization of the medication inside the main tube 1. The side wall of the main tube 1 is provided with scale markings 17 from top to bottom. The scale markings 17 have a lower scale line and an upper scale line. The lower scale line and the upper scale line are used to mark the lower limit and upper limit of the medication in the cavity of the main tube 1, respectively. The lower limit is the height of medication that needs to be retained in the cavity of the main tube 1 beforehand, and the upper limit is the maximum limit of the medication in the cavity of the main tube 1.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
