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 narrow jet hole 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] During the nebulizer treatment, the patient inhales the aerosol through an inhalation mask or mouthpiece connected to the nebulizer cup's nebulizer outlet. The distance between the nebulizer cup and the patient is very close, so the noise generated by the collision of the gas and liquid in the nebulizer cup with the collision surface will have a certain impact on the patient's emotions. In severe cases, it may cause the patient to feel anxious, rejected, and panic. Especially when used by children, the noise has a more obvious impact on the treatment effect.

[0005] Existing atomizer cup technology, such as the patent "Removable Silencing Atomizer Cup" with application number CN201420479998.3, discloses an atomizer cup capable of reducing noise. An adjustment hole is provided on the cup cover of the atomizer cup, and the noise can be controlled by controlling the size of the adjustment hole while air is entering. However, as the noise is reduced, the air intake is also reduced, which will affect the amount of mist output from the atomizer cup and reduce the treatment effect. Moreover, the atomizer cup needs to open the cup shell to add medicine, which is not very convenient to use.

[0006] 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

[0007] The invention aims to provide a low-noise atomizer cup which is convenient for adding medicine and taking in air.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is:

[0009] A low-noise atomizer cup that is convenient for adding medicine and letting in air, comprising a cup shell, wherein the cup shell has a cavity, and the cup shell is provided with an opening for adding medicine and letting in air into the cavity, wherein the opening is connected to the cavity through a channel;

[0010] The opening position is provided with a silencer;

[0011] The muffler device comprises a conduit portion and a support portion, wherein the conduit portion is a tube body, a pipe runs through the interior of the tube body, and the support portion is a bracket, which is fixed to the periphery of a port at one end of the conduit portion;

[0012] In the assembled state, the silencer is positioned at the opening position by the support portion, the conduit portion extends into the channel, the pipe in the conduit portion connects the volume cavity with the outside of the cup shell, and a silencer cavity is provided between the conduit portion and the channel around the through direction of the pipe, the silencer cavity and the pipe are connected to the volume cavity at the same end, so that the silencer cavity cooperates with the pipe to form a silencer structure.

[0013] Furthermore, the conduit portion is cylindrical, the aspect ratio of the pipe in the cylinder is greater than 1, the support portion is an annular disc-shaped bracket, the inner circle of the annular disc-shaped bracket is fixedly connected to the port at one end of the conduit portion, and the annular disc-shaped bracket and the pipe are coaxially arranged or eccentrically arranged; in the assembled state, the outer circle of the annular disc-shaped bracket and the opening are interference fit.

[0014] Furthermore, the silencing chamber is an annular cavity formed by the outer wall of the conduit portion, the inner wall of the channel and the disc-shaped end surface of the support portion close to one end of the cavity.

[0015] Furthermore, the silencing chamber is provided with spiral ribs surrounding the outer wall of the conduit portion.

[0016] Furthermore, the support portion is provided with an air inlet hole in its circular ring, and one end of the air inlet hole is connected to the outside of the cup shell, and the other end is connected to the containing cavity through the muffler cavity.

[0017] Furthermore, there is a clearance fit between the tube wall of the conduit portion and the inner wall of the channel, and a plurality of sieve holes are passed through the tube wall of the conduit portion along the through direction of the pipeline, and the plurality of sieve holes surround the pipeline to form the silencing chamber.

[0018] Furthermore, the support portion is provided with an air inlet hole in its circular ring, and one end of the air inlet hole is connected to the outside of the cup shell, and the other end is connected to the cavity through the gap between the outer wall of the conduit portion and the inner wall of the channel.

[0019] Furthermore, a positioning block is provided on the outer circle of the circular ring of the support portion, and a positioning groove matching with the positioning block is provided at the opening of the cup shell, and the positioning block is correspondingly embedded in the positioning groove in the assembled state.

[0020] The relevant contents in the above technical solution are explained as follows:

[0021] 1. In the above scheme, the opening is connected to the cavity through a channel. The channel is a path connecting the opening and the cavity. It can be a channel extending from the opening to the cavity, or a channel formed by the inner wall of the cavity close to the opening.

[0022] 2. In the above scheme, the silencer is arranged in the opening, so that the path for noise to enter and exit is changed from the original opening with a larger diameter to a pipe with a smaller diameter in the silencer. The best aspect ratio of the pipe is greater than 1. The pipe can be a straight pipe or a curved pipe, as long as the pipe can be inserted into the cavity during assembly. In this way, when in use, the pipe replaces the opening as the dosing port and the air inlet, while reducing the size of the noise propagation path and blocking part of the noise in the cavity. Even if another part of the noise is transmitted from the pipe, since the aspect ratio of the pipe is greater than 1, its longer inner wall has a certain reflection weakening effect on the noise, which can achieve the effect of silencing and reducing noise.

[0023] 3. In the above scheme, a silencer cavity is provided between the conduit portion and the cavity around the through-going direction of the pipeline. The silencer cavity may be an annular cavity, an annular cavity provided with spiral ribs, or a sieve hole in the inner wall of the conduit portion;

[0024] The function of the annular cavity is to block part of the noise inside, so that the noise is reflected back and forth inside the annular cavity, which consumes the energy of the noise. At the same time, the noise is reflected on the outer wall of the conduit to generate vibration, which can offset the vibration caused by the noise in the pipeline hitting the inner wall of the conduit, so that the noise is weakened, thus achieving the effect of silencing and reducing noise.

[0025] The annular cavity is provided with spiral ribs, and the design of the spiral ribs can better consume the energy of noise and further reduce noise;

[0026] The sieve holes on the inner wall of the duct can increase the air intake on the one hand, and also play a noise reduction role similar to the honeycomb structure on the other hand.

[0027] 4. In the above scheme, no matter what structure the silencer cavity has, the duct portion and the inner wall of the cavity are clearance-matched, and when the silencer cavity is an annular cavity with spiral ribs or a sieve hole in the inner wall of the duct portion, its better silencer effect enables the support portion to open an air inlet hole without weakening the silencer effect. The air inlet hole and the silencer cavity cooperate to increase the air intake volume while silencing and reducing noise.

[0028] 5. In the above scheme, the support part is a bracket for positioning, and its function is to position the silencer in the opening. Therefore, the support part can be a buckle structure matched with the opening, or a stud connected with the thread of the opening, or a circular disc with interference fit with the opening;

[0029] The conduit portion may be cylindrical or cylindrical with a square cross section, as long as a channel passes through the conduit portion;

[0030] The support portion and the pipeline are coaxially arranged or eccentrically arranged. When the pipeline is eccentrically arranged, the end of the pipeline will not face the noise source, and the noise reduction effect is better.

[0031] 6. In the above scheme, when the support part is in the shape of a circular disk, the positioning blocks around its outer circle cooperate with the positioning grooves in the opening, so that the silencer can be positioned more securely.

[0032] The working principle of the present invention is as follows:

[0033] A low-noise atomizer cup that is convenient for adding medicine and taking in air, wherein the cup shell of the atomizer cup has a cavity, and the cup shell is provided with an opening, wherein the muffler is positioned and installed in the opening, wherein the support portion of the muffler is positioned in the opening in the installed state, and the conduit portion of the muffler extends into the channel at the opening position;

[0034] A pipe with a length-to-diameter ratio greater than 1 runs through the conduit portion of the silencer, the pipe connecting the cavity and the outside of the cup shell, a circle of silencer cavity is separated between the conduit portion and the inner wall of the channel, the silencer cavity can block and weaken noise, and the silencer cavity can be an annular cavity, an annular cavity with spiral ribs, or a plurality of sieve holes in the inner wall of the conduit;

[0035] When the atomizer cup is working, the noise in the cavity is mainly transmitted from the opening. When the silencer is set in the opening, part of the noise in the cavity is transmitted from the pipe of the conduit part, and the other part of the noise enters the silencer cavity. The noise in the pipe is weakened by reflecting back and forth on the inner wall of the pipe and losing part of the energy. The noise in the silencer cavity is difficult to be transmitted outside the cavity, so it will continuously reflect and lose energy in the silencer cavity, and the vibration of the conduit part caused by the noise in the silencer cavity is offset by the vibration of the conduit part caused by the noise in the pipe, thereby further weakening the noise. In this way, the pipe cooperates with the silencer cavity to achieve a better silencer effect.

[0036] The advantages of the present invention are as follows:

[0037] 1. Good silencing effect: Pipes with a length-to-diameter ratio greater than 1 can effectively reduce noise, and the silencing chamber can further block and reduce noise. The cooperation between the pipe and the silencing chamber can cancel out the noise in the two, which further reduces the noise.

[0038] 2. Complete functions: While the silencer has the function of silencing and reducing noise, its pipeline can also be used as a drug adding channel and an air inlet channel, avoiding the inconvenience of adding drugs during the use of the atomizer cup and ensuring sufficient air intake; compared with the atomizer cup without an opening or with a normally closed opening, the atomizer cup of this design can facilitate drug addition and ensure air intake, and compared with the atomizer cup with an opening that is normally open, the atomizer cup of this design can silence and reduce noise.

[0039] 3. Small, light and easy to install: The silencer is a single component with a simple structure, light weight, and easy installation. It only needs to be positioned at the opening, making it less troublesome to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] Embodiment 1: See attached Figure 1 To Attachment Figure 4 , and attached Fig.11 To Attachment Fig.13, a low-noise atomizing cup that is convenient for adding medicine and taking in air, the atomizing cup comprises a cup shell 1, an inner cup 19 and a cup core 15;

[0062] As attached Figure 1 and attached Fig.13 As shown, the cup shell 1 has a cavity 2, the upper end of the cup shell 1 is an opening 3 that opens upward, a mist outlet 16 that connects the inside of the cavity 2 with the outside of the cavity 2 is provided on the side wall of the cup shell 1, a handle 21 is also provided on the side wall of the cup shell 1, and an air jet hole 22 with an inner diameter that gradually decreases from bottom to top is provided at the bottom of the cup shell, the air jet hole 22 extends out of the cavity 2 and is connected to compressed air, the upper end of the air jet hole 22 is conical, and the tip of the cone extends into the cavity 2 to form a jet port 17, and the jet port 17 is arranged upward;

[0063] The cup core 15 is a conical sleeve matched with the jet hole 22, and a connecting hole 20 is opened in the middle part thereof, and the two sides of the connecting hole 20 are connected to the cavities 2, and a collision column is set above the connecting hole 20, and the lower end surface of the collision column is a collision surface 18. In the installed state, the cup core 15 covers the upper side of the jet hole 22, and the connecting hole 20 of the cup core 15 is connected with the jet port 17 up and down, and the collision surface 18 and the jet port 17 are aligned up and down, and the distance between the collision surface 18 and the jet port 17 is the collision distance. The inner wall of the cup core 15 and the outer wall of the jet hole 22 form a gap match, and the gap between the two is the drainage gap 23 of the liquid medicine. When the compressed gas is ejected from the jet port 17, a low-pressure area is generated according to the Venturi principle, and the liquid medicine is sucked up from the drainage gap 23 under the influence of the pressure difference, and the sucked liquid medicine hits the collision surface 18 together with the compressed gas to form tiny droplets, and the droplets with small volume and light weight rise to form mist, and the droplets with large volume and heavy weight fall back into the liquid medicine;

[0064] As attached Fig.12 As shown, the inner cup 19 is a sleeve-shaped structure that is connected from top to bottom. A positioning groove 14 is provided on the inner wall of the upper end of the inner cup 19, and the size of the lower end port matches the cup core 15. When the inner cup 19 is embedded in the cavity 2, the upper outer wall of the inner cup 19 is interference-fitted with the opening 3, and the lower end port is against the cup core 15, so that the cup core 15 is positioned in the cavity 2, and the inner wall of the inner cup 19 forms a channel 4;

[0065] As attached Figure 3 and attached Figure 4 As shown, the silencer 5 comprises a conduit portion 6 and a support portion 7. The conduit portion 6 is a straight tube, and a pipe 8 having a length-to-diameter ratio greater than 1 passes through the tube body, and the cross-sectional dimension of the pipe 8 is smaller than the cross-sectional dimension of the channel 4. The support portion 7 is a disc-shaped ring bracket, and four positioning blocks 13 are arranged around the outer circumference of the disc-shaped ring bracket. The inner circumference of the disc-shaped ring bracket is fixed to the outer circumference of the port at one end of the conduit portion 6, forming a funnel-shaped silencer 5;

[0066] As attached Figure 1 and attached Figure 2 As shown, the muffler 5 is embedded in the upper opening of the inner cup 19, the positioning block 13 around the support portion 7 cooperates with the positioning groove 14, the outer circular edge of the support portion 7 is interference fit with the inner wall of the upper opening of the inner cup 19, the conduit portion 6 extends from the opening 3 along the channel 4 toward the cup core 15, the pipe 8 with a length-to-diameter ratio greater than 1 in the conduit portion 6 connects the cavity 2 with the outside of the cup shell, and the pipe 8 faces the cup core 15 in the up-down direction, the outer wall of the conduit portion 6 and the inner wall of the channel 4 are gap-matched, around the gap, the annular cavity formed by the outer wall of the conduit portion 6, the inner wall of the channel 4 and the disc-shaped end face of the support portion 7 close to one end of the cavity 2 constitutes a muffler cavity 9, one end of the muffler cavity 9 is sealed by the support portion 7, and the other end is connected with the cavity 2;

[0067] When in use, part of the noise generated by the collision of the collision surface 18 in the cup core 15 with the liquid medicine and the compressed gas is transmitted from the pipe 8 and is continuously reflected and weakened in the pipe 8, while the other part is blocked in the silencer chamber 9. While the noise is reflected and weakened in the silencer chamber 9, the vibration generated on the conduit part 6 and the vibration generated by the noise in the pipe 8 offset each other, further reducing the noise;

[0068] As attached Fig.13 As shown, when in use, the silencer 5 can also be used as a drug adding port and an air inlet. The air entering from the pipe 8 of the silencer 5 is sucked into the cavity 2 and goes out from the mist outlet 16 with the mist. The liquid medicine entering the cavity 2 from the pipe 8 sinks to the bottom of the cavity 2 and is sucked up from the drainage gap 23 due to the pressure difference, and hits the collision surface 18 together with the compressed gas entering from the jet hole 22 to form mist.

[0069] The support portion 7 in the first embodiment is a circular disc-shaped bracket, and may also be a buckle structure that cooperates with the opening 3, or a stud that is threadedly connected to the opening 3. When the opening 3 is a square opening, the support portion 7 may also be a square disc that is interference fit with the opening 3. As long as it is a bracket structure that can position the silencer at the position of the opening 3, it will suffice. However, this structural change does not bring about any other additional effects, and therefore can be considered to be substantially equivalent. Therefore, this structure should be included in the present invention, which is understandable and acceptable to those skilled in the art.

[0070] The conduit portion 6 in the first embodiment is a straight tube, and may also be other tube types such as a curved tube or a corrugated tube, as long as it is a tube that can extend from the opening 3 into the cavity 2. However, this structural change 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.

[0071] After experimental comparison, the noise level of the atomizer cup without the silencer 5 installed is 58.07 decibels when the collision distance is 1.2 mm in the working state; the noise level of the atomizer cup installed with the silencer 5 described in Example 1 is 53.58 decibels when the collision distance is 1.2 mm in the working state, and the noise reduction rate is 7.73%.

[0072] Embodiment 2: See attached Figure 5 To Attachment Figure 7 The difference between the second embodiment and the first embodiment is that:

[0073] The muffler cavity 9 is provided with a spiral rib 10 surrounding the outer wall of the conduit portion 6, and the support portion 7 is provided with an air inlet hole 12 in its circular ring, and one end of the air inlet hole is connected to the outside of the cup shell 1, and the other end is connected to the cavity 2 through the muffler cavity 9;

[0074] When installed, observing along the up and down direction, the width of the spiral rib 10 is equal to the cross-sectional ring width of the silencer cavity 9. Therefore, the spiral rib 10 is arranged in the silencer cavity 9. When noise propagates in the silencer cavity 9, it will be blocked by the spiral rib 10, thereby further weakening the noise. In addition, the support portion 7 can open an air intake hole 12 to further increase the air intake volume.

[0075] After experimental comparison, the noise of the atomizer cup without the silencer 5 installed is 58.07 decibels when the collision distance is 1.2 mm in the working state; the noise of the atomizer cup installed with the silencer 5 described in Example 2 is 56 decibels when the collision distance is 1.2 mm in the working state, and the noise reduction rate is 3.56%.

[0076] Embodiment 3: See attached Figure 8 To Attachment Fig.10 The difference between the third embodiment and the first embodiment is that:

[0077] A plurality of sieve holes 11 are formed in the pipe wall of the conduit portion 6 in the vertical direction. The plurality of sieve holes 11 are arranged around the pipe 8 and are separated between the conduit portion 6 and the channel 4 to form the muffler chamber 9.

[0078] In the installed state, there is a gap between the tube wall of the duct portion 6 and the inner wall of the channel 4, and the gap width is much smaller than the ring cross-section width of the silencer chamber 9 in the first embodiment. The silencer chamber 9 formed by the sieve holes 11 in the third embodiment replaces the silencer chamber 9 with an annular cavity structure. The structure in which the sieve holes 11 are arranged around the pipe 8 is similar to a honeycomb structure. Its narrow cross-section can reflect noise and weaken its energy, and the sieve holes 11 are connected from top to bottom, which can serve as a channel for air circulation to increase the air intake. Preferably, the support portion 7 is provided with an air intake hole 12 in its circular ring, one end of the air intake hole 12 is connected to the outside of the cup shell 1, and the other end is connected to the cavity 2 through the gap between the outer wall of the duct portion 6 and the inner wall of the channel 4, further increasing the air intake.

[0079] After experimental comparison, the noise level of the atomizer cup without the silencer 5 is 58.07 decibels when the collision distance is 1.2 mm when in working state; the noise level of the atomizer cup with the silencer 5 described in Example 3 is 54.77 decibels when the collision distance is 1.2 mm when in working state, and the noise reduction rate is 5.68%.

[0080] 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.
