Description

Technical Field

[0001] The invention relates to the field of medical atomizers, and in particular to a jet atomizer cup used in atomization inhalation therapy. Background Art

[0002] Nebulizer inhalation therapy is a treatment method for respiratory diseases such as asthma, bronchitis and pharyngitis. The jet nebulizer cup is currently the mainstream device for nebulizer inhalation therapy.

[0003] The main function of the nebulizer cup is to atomize the liquid medicine in the cup for inhalation by the patient. The atomization process uses the Venturi principle to send external compressed air (or oxygen) into the nebulizer cup through a pipe, and then spray it out at high speed from a jet hole with a narrow cross-section inside the nebulizer cup and hit the collision surface. The high-speed airflow generates a negative pressure area during the collision, so that the liquid medicine is sucked into the high-speed airflow under the pressure difference between the negative pressure area and the atmospheric pressure. Then the high-speed airflow carries the liquid medicine to hit the collision surface above the jet hole, forming a certain number and diameter of tiny droplets. This process is the "fogging" process of the nebulizer cup.

[0004] Generally speaking, patients of different ages, different lesion sites, different symptoms and different drugs will have different requirements for the atomization rate and atomization particle size. In some special cases, the same patient may have different requirements for the atomization rate and atomization particle size at different stages of treatment. For example, some patients with acute asthma attacks need to quickly inhale a large dose of bronchodilators at the beginning of treatment to quickly dilate the bronchi and relieve symptoms, while in the middle and late stages of treatment, they need a steady inhalation volume and smaller atomization particles to allow the drug to reach the affected area and ensure the duration of the drug's efficacy.

[0005] In the misting process, the collision distance between the jet hole and the collision surface is one of the key factors that determine the amount of mist (the atomization rate) and the diameter of the droplets. Within a certain collision distance range, as the collision distance increases, the atomization rate and the atomized particles will first increase and then decrease. The most important criterion for measuring the performance of the atomizer cup is the atomization rate and the size of the atomized particles it outputs.

[0006] In the existing atomizer cup technical solutions, such as the patent "Atomizer Can with Adjustable Atomized Particle Size" with application number CN201720848477.4, an atomizer can (i.e., atomizer cup) capable of adjusting the collision distance is disclosed. In this patent, the atomizer cup is used to adjust the distance between the collision surface and the jet hole up and down in a rotational manner through a threaded structure, thereby adjusting the droplet size; however, this structure cannot achieve accurate adjustment of the amount of fogging and the diameter of the droplets. In the process of moving the collision surface up and down by spiral transmission, firstly, the rotation adjustment angle cannot be accurately controlled. Secondly, even if a certain rotation angle is controlled, because the manufacturing material of the atomizer cup is generally plastic, its transmission accuracy is low, and the same rotation angle cannot guarantee that the lifting amount of the collision surface is the same each time, resulting in a large error.

[0007] Therefore, how to solve the above-mentioned deficiencies in the prior art has become a subject to be studied and solved by the present invention. Summary of the invention

[0008] The present invention aims to provide an atomizing cup with adjustable collision distance

[0009] In order to achieve the above object, the technical solution adopted by the present invention is:

[0010] An atomizing cup with adjustable collision distance comprises a cup shell and a venturi tube, wherein the cup shell has a cavity, and a jet port at one end of the venturi tube is located in the cavity;

[0011] A collision assembly is provided in the cavity, and the collision assembly includes an adjustment portion and a plurality of collision bodies;

[0012] The adjusting part is rotatably or slidably arranged in the cup shell, a plurality of collision bodies are connected to the adjusting part, and each collision body has a collision surface;

[0013] When the adjusting part rotates or slides, the adjusting part drives each collision body to move in the cavity. When observed along the jet direction of the jet port, each collision surface can face the jet port during the movement. At the same time, there is only one collision surface that can face the jet port, and in the facing state, the collision distances between each collision surface and the jet port are not equal.

[0014] Furthermore, a part of the adjusting part is rotatably or slidably arranged in the cup shell, and another part is exposed outside the cup shell as an operating part;

[0015] Each of the collision bodies is a column, and the columns are dispersedly arranged inside the cavity. One end of each column is fixedly connected to the part of the adjustment part that rotates or slides in the cup shell, and the other end serves as a collision surface close to the jet port.

[0016] Furthermore, the adjustment part includes a turntable and a knob, the turntable is rotatably connected to the cup shell, and the axis of rotation of the turntable is in the same direction as the jet direction of the jet port, and the knob is fixed on the turntable and exposed outside the cup shell to form an operating position;

[0017] Each of the collision bodies is provided with a column extending along the jet direction, and a plurality of columns are fixedly connected to the rotating disk in an arrangement manner surrounding the axis, and the axial distances of the collision bodies from the axis are equal; and in the jet direction, the collision distances between the collision surfaces and the jet orifice are not equal;

[0018] In the rotating state, the motion trajectories of each collision surface form a ring, and when observed along the jet direction, the jet port is located on the ring of the motion trajectory of each collision surface, so that the jet port can face each collision surface at different collision distances.

[0019] Furthermore, the collision assembly also includes a dosing tube;

[0020] The dosing tube is a hollow pipe extending along the jet direction, one end of the dosing tube is passed through and fixed in the turntable and the knob, the other end of the dosing tube is arranged in the cavity, and each of the collision bodies avoids the hollow part of the dosing tube and is fixed on the annular end face of one end of the dosing tube arranged in the cavity.

[0021] Furthermore, the adjusting part is a slider, which is slidably arranged in the cup shell perpendicular to the jet direction, and one end surface of the slider is exposed outside the cup shell to form an operating position;

[0022] Each of the collision bodies is a column extending along the jet direction, and a plurality of columns are fixedly connected to the slider in a mutually parallel arrangement, and the arrangement direction is in the same direction as the sliding direction of the slider;

[0023] In the sliding state, the motion trajectory of each collision surface forms a straight strip, and when observed along the jet direction, the jet port is located on the motion trajectory of each collision surface, so that the jet port can face each collision surface at different collision distances.

[0024] Furthermore, the collision assembly also includes a dosing tube;

[0025] The dosing tube is a hollow pipe extending along the jet direction. One end of the dosing tube is fixedly inserted into the cup shell to avoid the sliding track of the slider, and the other end of the dosing tube is arranged in the cavity, so that the dosing tube connects the outside of the cup shell with the cavity.

[0026] Furthermore, the adjustment part is rotatably connected to the cup shell, and the axis of rotation forms an obtuse angle with the jet direction of the jet port;

[0027] Each of the collision bodies is a bent cylinder, and the collision surface at one end of each bent cylinder is arranged around the axis and fixedly connected to the adjustment part, and the axial distance between each collision surface and the axis is equal;

[0028] In the rotating state, the motion trajectory of each collision surface forms a circular ring, and the circular trajectory is not perpendicular to the jet direction. When observed along the jet direction, the jet orifice is located on the motion trajectory of each collision surface, and the collision distances between each collision surface and the jet orifice are not equal, so that the jet orifice can face each collision surface at different collision distances.

[0029] Furthermore, the adjusting part is provided with an indicating arrow, and the cup shell is engraved with gear numbers representing different collision distances. When the adjusting part drives each collision body to move, the indicating arrow points to different gear numbers.

[0030] Furthermore, the collision distance between each of the collision surfaces and the jet orifice is 0.1 mm to 1.9 mm.

[0031] The relevant contents in the above technical solution are explained as follows:

[0032] 1. In the above scheme, the collision body is a component with a collision surface, which can be a cylinder or a frustum, as long as it has a collision surface and has a certain length in space;

[0033] When the collision body is a column, one end is a collision surface, and the other end is connected to the adjustment part, which can be a fixed connection or a detachable positioning connection, so that when the operator operates the adjustment part, each collision body can rotate or translate with the adjustment part, and the jet port is located on the motion trajectory of each collision surface, so that different collision surfaces are switched to face the jet port, and the collision distance is changed to achieve the effect of fogging amount and droplet diameter size;

[0034] This adjustment method is gear adjustment, switching different collision surfaces to face the jet orifice is gear shifting, and the collision distance brought by each gear shift is different, and each collision distance is quantitative. Compared with the adjustment method of changing the collision distance by spiral transmission in the prior art, this gear adjustment method does not change the collision distance between each collision surface and the jet orifice, but switches different collision surfaces and changes the collision distance, thereby reducing human adjustment errors and avoiding transmission errors.

[0035] Indicator marks can be set on the adjustment part according to different gears, and damping structures can also be set in the matching parts of the adjustment part and the cup shell corresponding to different gears. For example, a convex point is set on the operating part, and a plurality of pits are set in the cup shell accordingly. When the convex point enters a pit, it means that it is adjusted to a certain gear. When the convex point leaves the pit, the resistance is relatively large. The operator can judge whether the adjustment is in place according to the indicator mark or the operating resistance. Since each collision distance is a fixed amount, it is only necessary to adjust the collision surface to be opposite to the jet outlet.

[0036] 2. In the above scheme, the collision bodies are dispersedly arranged so that the collision surfaces are separated from each other, so that when one of the collision surfaces faces the jet orifice, the other collision surfaces will not interfere with the generation of mist;

[0037] If the collision surfaces are close to each other, or combined into an uneven arc surface, the mist generated by the collision will adhere to other collision surfaces to form water droplets, reducing the amount of mist output. Therefore, multiple collision bodies are arranged in a dispersed manner to maintain the best mist output effect.

[0038] 3. In the above scheme, when the adjustment part is a combination structure of a turntable and a knob, and the axis of rotation of the turntable is in the same direction as the jet direction, the turntable part and the cup shell form a rotation connection, which can be a pivot structure connection between the turntable and the cup shell, or a rotation connection structure in which the turntable is embedded in the shell wall of the cup shell;

[0039] The knob is fixed on the turntable and is used to provide an operator's operating action part. The collision body is fixedly connected to the turntable, so that the turntable can drive each collision body to rotate around the axis when it rotates, so that the collision surface of each collision body moves parallel to the jet port, thereby changing the collision distance. Although the collision distances between different collision surfaces and the jet port are different, the collision distance will not change due to the operator's operating method, thereby achieving stable adjustment of the mist output amount.

[0040] 4. In the above scheme, when the adjusting part is a slider, the slider is slidably connected to the cup shell, and the sliding direction of the slider is perpendicular to the jet direction. Each collision body is fixedly connected to the slider and arranged in parallel along the sliding direction of the slider. The collision distance between the collision surface of each collision body and the jet port is different, but each collision distance is fixed, so that the operator can change different collision distances by sliding the slider, and the collision distance will not change due to the operator's operating method, thereby realizing stable adjustment of the mist output.

[0041] 5. In the above scheme, when the adjustment part is a combination structure of a turntable and a knob, and the axis of rotation of the turntable forms an obtuse angle with the jet direction, the turntable part is connected to the cup shell in rotation, and the turntable and the cup shell may be a pivot structure, or the turntable may be embedded in the shell wall of the cup shell and rotate, and the knob is fixed on the turntable to provide an operator's operating part;

[0042] Each collision body fixedly connected to the turntable is of a bent structure, so that it can cooperate with the turntable whose axis is not in the same direction as the jet direction, so that when the collision body rotates with the turntable, each collision surface can face the jet outlet in the jet direction, and the collision distance between each collision surface and the jet outlet is different. Although the collision distances are different, the collision distances will not change due to the operator's operating method, thereby achieving stable adjustment of the mist output amount.

[0043] 6. In the above scheme, the arrangement of the dosing pipe can be arranged between the adjustment part and the collision body, or it can be arranged separately on the cup shell to provide a pipeline for dosing and ventilation;

[0044] When the dosing tube is arranged between the adjustment part and the collision body, one end of the dosing tube needs to pass through the adjustment part, such as being inserted into the turntable and the knob (i.e., the operating part), and the other end is fixedly connected to each collision body and needs to avoid the hollow part of the dosing tube, so that the dosing tube connects the outside of the cup shell and the cavity.

[0045] 7. In the above scheme, the arrangement of each gear number on the cup shell corresponds to the position of each collision body. When the adjustment part is rotated to make the indicating arrow correspond to each gear number, the collision surface of each collision body can just face the jet port.

[0046] 8. In the above scheme, when the collision distance between each collision surface and the jet outlet is 0.1 mm to 1.9 mm, the mist emission effect is best.

[0047] The working principle of the present invention is as follows:

[0048] The collision assembly is an integrated structure formed by the adjusting part and a plurality of the collision bodies being fixedly connected up and down. The adjusting part is rotated or slid to be positioned in the cup shell. The operator rotates or moves the adjusting part to drive the collision surfaces on the collision bodies below to rotate around the jet direction or move perpendicular to the jet direction, thereby switching different collision surfaces to face the jet port to achieve the purpose of adjusting the collision distance.

[0049] The advantages of the present invention are as follows:

[0050] 1. Easy to use: The operator can change the collision distance by rotating or sliding the adjustment part. Preferably, the collision component is also provided with a drug adding port, which can add drugs into the cavity without opening the cup shell, and is easy to use.

[0051] 2. Small adjustment error: By rotating the adjustment part to switch different collision bodies facing the jet orifice, different collision distances are fixed. The operator only needs to switch the collision body, avoiding the deterioration of the mist output effect caused by human adjustment errors and transmission errors of the atomizer cup.

[0052] 3. Good mist discharge effect: The collision bodies are dispersedly arranged, so that when a single collision surface is facing the jet orifice in the working state, other collision surfaces will not interfere with the mist discharge, ensuring a good mist discharge effect.

[0069] Embodiment 1: See attached Figure 1 To Attachment Figure 5 As shown, an atomizing cup with adjustable collision distance includes a cup shell 1, a cup cover 15, a cup core 16, a mist outlet 21 and a venturi tube 20;

[0070] The cup shell 1 has a cavity 2, and the portion of the cavity 2 containing the liquid medicine is defined as the lower portion;

[0071] The cup shell 1 is composed of an upper cup 17 and a lower cup 18, the lower end of the upper cup 17 is embedded and positioned in the upper end opening of the lower cup 18; the venturi tube 20 is positioned at the bottom end of the lower cup 18, and the jet port 4 of the venturi tube 20 is located in the cavity 2; the cup core 16 is covered on the upper end of the venturi tube 20 in a clearance fit manner, and the gap between the two is a drainage gap 22, and a hole is provided in the cup core 16 for the jet to pass through, and in the assembled state, the hole is aligned with the jet port 4 up and down, and the lower end of the upper cup 17 extends downward and abuts on the cup core 16, so as to position the cup core 16 in the cavity 2; the mist outlet 21 is opened on the upper cup 17, and the upper end of the upper cup 17 is an opening, and a partition 19 is provided in the opening, and the cup cover 15 is positioned above the partition 19 in the opening;

[0072] The chamber 2 is provided with a collision assembly, which includes an adjustment portion 5, three collision bodies 6 and a dosing tube 11;

[0073] The adjusting part 5 includes a turntable 8 and a knob 9. The turntable 8 is embedded between the partition 19 and the cup cover 15, and the axis 10 of rotation of the turntable 8 is in the same direction as the jet direction 3 of the jet port 4, both in the up-down direction. The knob 9 is fixed on the turntable 8, passes through and is exposed at the upper end of the cup cover 15 to form an operating position.

[0074] The dosing tube 11 is a hollow pipe extending in the up-down direction. The upper end of the dosing tube 11 is passed through and fixed in the turntable 8 and the knob 9, so that the upper end is connected to the outside of the cup shell 1, and the lower end of the dosing tube 11 is arranged in the cavity 2, so that the lower end is connected to the cavity 2.

[0075] The turntable 8 is embedded between the partition 19 and the cup cover 15, the upper end of the turntable 8 is fixed with a knob 9, and the lower end of the turntable 8 is fixed with a dosing tube 11, forming a pivot connection structure between the turntable 8 and the cup shell 1;

[0076] The three cylindrical collision bodies 6 extend in the up-down direction, and are arranged in a dispersed manner around the axis 10, and are fixed on the annular end surface of the lower end of the dosing tube 11 avoiding the hollow part of the dosing tube 11. The axial distances of the three collision bodies 6 from the axis 10 are equal; and in the up-down direction, the collision distances between the three collision surfaces 7 and the jet port 4 are not equal;

[0077] In the rotating state, the motion trajectories of each collision surface 7 form a ring, and when viewed from the up and down direction, the jet port 4 is located on the ring of the motion trajectory of each collision surface 7. At the same time, there is only one collision surface 7 that can face the jet port 4, and in the facing state, the collision distances between each collision surface 7 and the jet port 4 are not equal, so the operator can change the collision distance by turning the knob 9, thereby adjusting the amount of mist output;

[0078] Preferably, the knob 9 is provided with an indicating arrow 13, and the cup cover 15 is provided with three gear numbers 14, and the three gear numbers 14 correspond to three collision bodies 6. When the operator rotates the knob 9 so that the indicating arrow 13 above is aligned with one of the gear numbers 14, the collision surface 7 of the collision body 6 represented by the gear number 14 is also located just above the jet port 4;

[0079] When the atomizer cup is in working state, the flow direction of gas and liquid in it is as shown in the following figure. Figure 8 As shown, when the compressed gas in the venturi tube 20 is ejected from the jet port 4, a low-pressure area is generated according to the Venturi principle, and the liquid medicine is sucked up from the drainage gap 22 under the influence of the pressure difference, and the sucked liquid medicine hits the collision surface 7 at the lower end of the collision body 6 together with the compressed gas, forming tiny droplets, and the droplets with small volume and light weight rise to form mist, which is sucked out from the mist outlet 21 by the patient, and the droplets with large volume and heavy weight fall back into the liquid medicine; when adding medicine, the liquid medicine enters the cavity 2 from the dosing tube 11, and the gas also enters the cavity 2 from the dosing tube 11, and is sucked away by the patient from the mist outlet 21;

[0080] The adjustment part 5 in the first embodiment is a combination structure of a turntable 8 and a knob 9, and can also be a combination of a pin and a lever. The pin is inserted into the cup cover 15 along the up-down direction, and one end of the lever is inserted into the pin perpendicular to the up-down direction, and the other end extends out of the cup shell. The operator can drive the pin to rotate by turning the lever, but this structure does not bring any other additional effects, so it can be considered to be substantially equivalent. Therefore, this structure should be included in the present invention, which can be understood and accepted by technical personnel in this field.

[0081] The collision body 6 and the adjusting part 5 in the first embodiment are fixedly connected via the dosing tube 11, or the collision body 6 and the adjusting part 5 can be directly fixedly connected, and the dosing tube 11 can be separately arranged on the cup cover 15, or the collision body 6 can be arranged at the lower end of the adjusting part 5 in a detachable positioning installation manner, but this structure does not bring any other additional effects, so it can be considered to be substantially equivalent, so this structure should be included in the present invention, which can be understood and accepted by technical personnel in this field.

[0082] Embodiment 2: See attached Figure 6 The difference between the second embodiment and the first embodiment is that:

[0083] The adjusting part 5 is a slider 12, which is slidably arranged in the partition 19 at the upper end of the cup shell 1 in a vertical direction, and the upper end surface of the slider 12 is exposed above the partition 19 to form an operating position, and the lower end surface of the slider 12 is fixedly connected to the upper end of each of the collision bodies 6;

[0084] Each of the collision bodies 6 is extended in the up-down direction and fixedly connected to the slider 12 in a mutually parallel arrangement, and the arrangement direction is in the same direction as the sliding direction of the slider 12;

[0085] In the sliding state, the motion trajectory of each collision surface 7 forms a straight strip, and when viewed from the up and down direction, the jet port 4 is located on the motion trajectory of each collision surface 7, so that the jet port 4 can face each collision surface 7 at different collision distances;

[0086] Preferably, the collision assembly further includes a dosing tube 11; the dosing tube 11 is a hollow pipe extending in the up-down direction, the upper end of the dosing tube 11 avoids the sliding track of the slider 12 and is fixedly penetrated through the upper end of the cup shell 1, and the lower end of the dosing tube 11 is arranged in the cavity 2, so that the dosing tube 11 connects the outside of the cup shell 1 with the cavity 2;

[0087] It can be seen that the structure of this collision component can still realize the function of changing the collision distance by operating the adjustment part, and does not bring any other additional effects. Therefore, it can be considered to be substantially equivalent. Therefore, this structure should be included in the present invention, which can be understood and accepted by technical personnel in this field.

[0088] Embodiment 3: See attached Figure 7 The difference between the third embodiment and the first embodiment is that:

[0089] The adjusting portion 5 is rotatably connected to the cup shell 1, and the axis 10 of rotation of the turntable 8 forms an obtuse angle with the jet direction 3 of the jet port 4;

[0090] Each of the collision bodies 6 is a bent cylinder, and the collision surface 7 of each collision body 6 is arranged around the rotating shaft 10 and is fixedly connected to the adjustment part 5, and the axial distance between each collision surface 7 and the rotating shaft 10 is equal;

[0091] In the rotating state, the motion trajectory of each collision surface 7 forms a ring, and the ring trajectory is not perpendicular to the jet direction 3. When observed along the jet direction 3, the jet port 4 is located on the motion trajectory of each collision surface 7, and the collision distances between each collision surface 7 and the jet port 4 are not equal, so that the jet port 4 can face each collision surface 7 at different collision distances.

[0092] It can be seen that the structure of this collision component can still realize the function of changing the collision distance by operating the adjustment part, and does not bring any other additional effects. Therefore, it can be considered to be substantially equivalent. Therefore, this structure should be included in the present invention, which can be understood and accepted by technical personnel in this field.

[0093] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
