Description

Technical Field

[0001] The utility model relates to the technical field of atomizer cups, in particular to a low-noise atomizer cup with adjustable atomization volume. Background Art

[0002] A nebulizer cup is a container specifically designed for nebulization therapy. It converts liquids such as medication or saline into fine aerosolized particles, which are then inhaled by the patient. Compressed air nebulizer cups use a compressor to provide high-flow compressed air to the nebulizer cup. The huge air pressure difference creates a cutting effect on the surface of the medication liquid, forming aerosolized particles.

[0003] In reality, different patients' conditions, ages, physical conditions, and other factors determine their varying needs for atomization volume. Excessive atomization volume can irritate the respiratory mucosa, causing adverse reactions such as coughing and dyspnea. Therefore, adjusting the atomization volume can ensure that patients receive a personalized treatment experience, improve treatment efficacy, and ensure that the drug enters the patient's body at the optimal concentration and speed, thereby increasing drug utilization, reducing drug waste, and minimizing the occurrence of adverse reactions. Adjusting the atomization volume of the atomizer cup generally depends on the design and operation of the nebulizer system.

[0036] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0037] If the present invention involves directions (e.g., up, down, left, right, front, back, outside, inside, etc.), the directions involved need to be defined, for example, "To clearly express the positions and directions described in this invention, the end closest to the operator is the proximal end, and the end away from the operator is the distal end." Or, the paper can be used as a reference for definition. Of course, if the subsequent description defines the positional relationship between the two by mutual reference, this definition does not need to be included here.

[0038] A low-noise atomizer cup with adjustable atomization volume, such as Figures 1-2 As shown, it includes a cup body, a fog storage bin 3 and an atomizing piece 4, the fog storage bin 3 and the atomizing piece 4 are arranged in the cup body, the cup body includes an upper cup body 1 and a lower cup body 2 arranged up and down, the fog storage bin 3 is arranged in the upper cup body 1, the fog storage bin 3 is rotatably connected to the upper cup body 1, the fog storage bin 3 is fixedly connected to the lower cup body 2, and a fog outlet 108 is provided at the upper end of the upper cup body 1, the lower cup body 2 is used to hold the medicine liquid, the atomizing piece 4 is arranged in the lower cup body 2 and is used to atomize the medicine liquid, and the atomized medicine mist flows from the transport fog storage bin 3 to the fog outlet 108 of the upper cup body 1 and flows out.

[0039] like Figures 3 to 7As shown, an air inlet 101 is provided between the mist storage bin 3 and the upper cup body 1, and two opposite air inlets 3021 are provided on the side wall of the mist storage bin 3. The air entering from the air inlet 101 can enter the air inlet 3021. The upper cup body 1 includes a mist outlet pipe 102, an upper cup body 103 and an adjustment portion 104 arranged in sequence from top to bottom. The top of the mist outlet pipe 102 is the mist outlet 108. The adjustment portion 104 can block the air inlet 3021. The adjustment portion 1 04 includes two sections of semicircular rings, and the two sections of the semicircular rings correspond one to one with the two air inlets 3021 of the air inlet pipe 302. The two sections of the semicircular rings are connected end to end to form a ring with the same outer diameter as the upper cup body 103. The wall thickness of the semicircular rings continuously decreases along the circumferential direction. When the air inlet 3021 is located at the point where the wall thickness of the semicircular ring is the largest, that is, the radial distance between the semicircular ring and the air inlet 3021 is zero, the air inlet 3021 is blocked, and no gas can enter the air inlet 3021. Rotate the upper cup body 1 or the mist storage bin 3 to change the relative position between the air inlet 3021 and the semicircular ring, that is, change the distance between the semicircular ring and the air inlet 3021. When the wall thickness of the semicircular ring blocking the air inlet 3021 is smaller, the radial distance between the semicircular ring and the air inlet 3021 is larger, and more gas can enter the air inlet 3021, that is, the greater the air intake.

[0040] like Figures 5-7 As shown, the mist storage chamber 3 includes an outer tube body 301, an air inlet pipe 302 and an inner tube body 303. The outer tube body 301 and the inner tube body 303 are coaxially arranged. The inner tube body 303 is arranged in the outer tube body 301. One end of the atomizing plate 4 is connected to the bottom end of the inner tube body 303. The air inlet pipe 302 passes through the side wall of the outer tube body 301. The middle part of the air inlet pipe 302 is connected to the top of the inner tube body 303. The air inlet pipe 302 forms an air inlet 3021 on the outer wall of the outer tube body 301. External air enters the inner tube body 303 from the air inlet 3021. Preferably, the air inlet 3021 of the air inlet pipe 302 is a countersunk hole.

[0041] As an embodiment of the present invention, an annular platform 304 is provided at the bottom of the outer tube 301, and a plurality of limiting portions 105 extending toward the lower cup body 2 are provided on the adjusting portion 104, and the limiting portions 105 abut against the annular platform 304. Preferably, there are at least two limiting portions 105 evenly distributed along the circumference, and the limiting portions 105 abut against the annular platform 304, so that a gap exists between the semicircular ring and the annular platform 304, that is, the aforementioned air inlet 101 is formed, that is, when the semicircular ring does not completely block the air inlet 3021, a gap exists between the upper cup body 1 and the air inlet 3021, and gas can enter the air inlet 3021 from the air inlet 101.

[0042] As an embodiment of the present invention, the outer tube 301 is threadedly connected to the lower cup 2, and the connection is located below the annular platform 304. Specifically, the portion of the outer tube 301 located below the annular platform 304 is the lower connecting end, which is provided with an external thread 309. The inner wall of the lower cup 2 is provided with an internal thread 206 that matches the external thread 309. This provides a convenient and tight connection while preventing the mist from flowing out of the atomizer cup.

[0043] like Figures 3-4 As shown, the overall shape of the upper cup body 1 is cylindrical, so that the flow of the medicine mist in the upper cup body 1 has no blind spots. The upper cup body 1 has no openings except the mist outlet 108 and the lower connecting end, which can effectively reduce the noise generated by the high-speed airflow hitting the medicine liquid.

[0044] Two arc-shaped grooves 305 are provided on the outer tube body 301, and the two arc-shaped grooves 305 are not connected. The arc-shaped grooves 305 extend circumferentially along the outer wall of the outer tube body 301. Two protrusions 106 corresponding to the two arc-shaped grooves 305 are provided on the inner wall of the upper cup body 1. The protrusions 106 can slide circumferentially along the outer wall of the outer tube body 301 in the arc-shaped grooves 305. As the position of the protrusions 106 in the arc-shaped grooves 305 changes, the wall thickness of the semicircular ring covering the air inlet 3021 also changes accordingly. Specifically, when the protrusion 106 is located at both ends of the arc-shaped groove 305, the wall thickness of the semicircular ring that blocks the air inlet 3021 is the maximum wall thickness and the minimum wall thickness, that is, if it is defined that when the protrusion 106 is located at the first end in the arc-shaped groove 305, the wall thickness of the semicircular ring that blocks the air inlet 3021 is the maximum wall thickness, then at this time the air inlet 3021 is completely blocked, the air inlet pipe 302 is closed, and no gas enters the air inlet pipe 302 and the inner tube body 303; when the protrusion 106 is located at the second end in the arc-shaped groove 305, the air inlet is blocked. The wall thickness of the semicircular ring 3021 is the minimum wall thickness, and the air inlet 3021 is in the maximum air intake state at this time; in the process of the protrusion 106 sliding from the first end to the second end of the arc-shaped groove 305, the wall thickness of the semicircular ring blocking the air inlet 3021 gradually decreases, and the air intake volume of the air inlet 3021 gradually increases; and in the process of the protrusion 106 sliding from the second end to the first end of the arc-shaped groove 305, the wall thickness of the semicircular ring blocking the air inlet 3021 gradually increases, and the air intake volume of the air inlet 3021 gradually decreases; in this way, stepless adjustment of the air intake volume is achieved.

[0045] As an embodiment of the present invention, the arcuate channel 305 further includes a channel inlet 306, which is provided at the edge of the outer tube 301 and communicates with the arcuate channel 305. Through the inlet of the arcuate channel 305, the protrusion 106 can be conveniently slid into the arcuate channel 305. Preferably, the extending direction of the channel inlet 306 is perpendicular to the extending direction of the arcuate channel 305. An indicator mark is provided at the bottom of the upper cup body 1, and the protrusion 106 can be quickly inserted into the channel inlet 306 along the direction indicated by the indicator mark.

[0046] As an embodiment of the present invention, Figures 3-4 As shown, a plurality of arc-shaped fog-blocking strips 1072 are provided on the inner wall of the upper cup body 1. The arc-shaped fog-blocking strips 1072 are separately provided and not connected to each other. The arc-shaped fog-blocking strips 1072 are used to block the medicine mist to prevent the medicine mist from sticking to the inner wall of the upper cup body 1 and flowing out of the upper cup body 1.

[0047] As another embodiment of the present invention, Figures 5-6 As shown, an annular fog shielding strip 1071 is provided on the inner wall of the upper cup body 1, and the annular fog shielding strip 1071 is used to block the medicine mist. The upper end of the outer tube body 301 is clamped between the upper cup body 1 and the annular fog shielding strip 1071. Specifically, the upper end of the outer tube body 301 is interference fit with the upper cup body 1 and the annular fog shielding strip 1071. The provision of the annular fog shielding strip 1071 reduces the loss of medicine mist particles and reduces the residual amount.

[0048] As one embodiment of the present invention, a guide slope 307 is provided at the junction of the inner tube 303 and the air inlet pipe 302. This guide slope 307 is used to guide the flow of the medicine mist. Specifically, the junction of the air inlet pipe 302 and the inner tube 303 is truncated cone-shaped. In the direction of the medicine mist flow, the path gradually widens from narrow. The truncated cone's slope effectively guides the discharge of the medicine mist, thereby reducing the loss of atomized particles.

[0049] like Figures 8-9 As shown, the lower cup body 2 includes a lower cup body 201 and a lower bracket 202 arranged in sequence from top to bottom. A liquid storage cavity is formed in the lower cup body 201, and the liquid storage cavity is used to store liquid medicine. The lower bracket 202 forms an annular structure, which is convenient for users to grasp. The bottom surface of the lower bracket 202 is flat, which is convenient for being placed flat on a horizontal surface such as a desktop. The bottom of the lower bracket 202 is provided with an internal card slot inwardly, through which the lower bracket 202 can be installed on an external air source. The bottom of the lower cup body 201 is provided with an atomization air inlet pipe 203, and the external air source supplies high-speed airflow to the liquid storage cavity through the atomization air inlet pipe 203. The lower cup body 201 is translucent, and a scale mark is provided on the side wall of the lower cup body 201.

[0050] like Figures 10-11 As shown, the lower end of the atomizing sheet 4 is arranged on the atomizing air inlet pipe 203, and the upper end of the atomizing sheet 4 is inserted into the inner tube body 303 of the fog storage chamber 3. Specifically, a mounting slot 308 is provided in the inner tube body 303, and the mounting slot 308 is used to install and connect the atomizing sheet 4. The part of the atomizing air inlet pipe 203 that extends into the interior of the lower cup body 201 is a hollow cone 204, and a first air outlet 205 is provided at the top of the hollow cone 204. The atomizing sheet 4 includes a conical support 401 and an impact column 402 mounted on the conical support 401. The conical support 401 is sleeved on the outside of the hollow cone 204, and a second air outlet 403 corresponding to the first air outlet 205 is provided on the top of the conical support 401. The second air outlet 403 There is a gap between the conical support 401 and the impact column 402. A medicine feed groove 404 is provided on the inner wall of the conical support 401. A medicine feed channel is formed between the medicine feed groove 404 and the outer conical surface of the hollow cone 204. The airflow entering from the atomizing air inlet pipe 203 is converted into a high-speed airflow at the first air outlet 205. The medicine liquid in the liquid storage chamber enters the medicine feed channel under the action of negative pressure, and is blown by the high-speed airflow at the first air outlet 205 through the second air outlet 403 and impacts the impact column 402 to form medicine mist.

[0051] The installation method of the present invention is as follows: insert the atomizing sheet 4 into the inner tube 303, then screw the atomizing chamber into the lower cup 2, and finally insert the protrusion 106 of the upper cup 1 into the groove inlet 306 and into the annular groove to achieve installation and fixation.

[0052] The atomizer cup provided by the present invention can realize stepless adjustment of the air intake volume of the air inlet 3021 by setting a semicircular ring with continuously changing wall thickness between the upper cup body 1 and the mist storage bin 3, and thus realize stepless adjustment of the atomization volume by cooperating with the rotational connection between the upper cup body 1 and the mist storage bin 3.
