Description

Technical Field

[0001] This application relates to the technical field of atomizers, and more particularly to an atomizing device. Background Technology

[0002] A nebulizer is used to atomize a test solution. It is a crucial component of an atomization system, and its performance significantly impacts the precision of the measurement and reduces chemical interference. Therefore, nebulizers are required to produce stable sprays, fine and uniform droplets, and high atomization efficiency.

[0003] Depending on their intended use, nebulizers come in various types, such as air humidifiers and medical nebulizers.

[0004] Existing nebulizers with heating functions heat the liquid medication to be atomized. During the heating process, the liquid medication comes into direct contact with the nebulizer body for atomization. However, due to the long atomization time, substances from the liquid medication can easily accumulate within the relatively still nebulizer body, resulting in uneven medication content in the atomized mist. This is especially true for nebulizers with liquid absorption methods that are either bottom-up or top-down, leading to variations in the medication concentration in the mist. Summary of the Invention

[0005] In order to improve the stability of drug content in the atomized mist, this application provides an atomizing device.

[0006] Atomizing device includes a cylindrical body and a cover. The cylindrical body has an upper-opening receiving cavity. The cover is used to cover the cylindrical body. The cylindrical body also has a heater and an atomizing plate. The cover has an exhaust assembly for discharging water mist. It also includes a separator sleeve and a liquid storage tank. The separator sleeve has an upward-opening drug storage cavity. The separator sleeve is fitted inside the cylindrical body and located above the heater and the atomizing plate. A thin film is provided on the bottom surface of the separator sleeve. The liquid storage tank is fixed to the cover. A drain pipe for communicating with the drug storage cavity is fixedly connected to the liquid storage tank. The end of the drain pipe has a liquid outlet with an internal cavity extending through it. The liquid outlet is screwed onto the drain pipe. A limiting block is fixedly connected inside the liquid outlet head. The limiting block has a through hole. A push rod is slidably mounted on the limiting block and is slidably mounted inside the through hole. The diameter of the push rod is smaller than that of the through hole. A baffle plate for blocking the through hole is fixedly connected to the end of the push rod facing the drain pipe. The baffle plate is smaller than the inner diameter of the drain pipe. A first spring is provided between the end of the push rod away from the baffle plate and the limiting block. Under the action of the first spring, the push rod pulls the baffle plate to block the inner cavity of the liquid outlet head. A top block for pressing the push rod to compress the first spring is fixedly connected to the bottom surface of the separator sleeve. The liquid outlet head abuts against the bottom surface of the separator sleeve. A drain port is opened on the periphery of the liquid outlet head.

[0007] By adopting the above technical solution, during use, the operator injects clean water into the containing cavity, then places the separator sleeve inside the cylinder, aligns the diaphragm with the atomizing plate, and places the cover on the cylinder, covering the opening of the liquid chamber. The operator then installs the storage tank on the cover and connects the drain pipe to the storage chamber, aligning the outlet head on the drain pipe with the top block. Under the weight of the storage tank, the outlet pipe abuts against the bottom surface of the separator sleeve. During this process, the top block presses against the push rod, which, under pressure, compresses the first spring. The push rod also moves the baffle to release the blockage of the through hole, allowing the liquid in the storage tank to flow into the through hole through the gap between the baffle and the inner wall of the drain pipe. Then, it flows through the gap between the push rod and the side wall of the through hole to the other end of the outlet head, and finally flows into the storage chamber through the drain port, thus achieving separation between the liquid and the clean water.

[0008] When the liquid level in the storage chamber is higher than the height of the drain outlet, the liquid level in the storage tank will not continue to be filled due to the pressure of the liquid in the storage chamber. When the liquid level drops to the height of the drain outlet during use, the storage tank will continue to fill the storage chamber with liquid through the principle of negative pressure, so that the liquid level in the storage chamber is basically kept at a certain height during use.

[0009] After the liquid medicine enters the storage chamber, it fills the top of the diaphragm. When the heater heats the water, the atomizing plate is activated to atomize the water. The atomized mist overflows from the liquid medicine after passing through the diaphragm and is discharged through the exhaust assembly. During this process, since the liquid medicine height is basically constant, the amount of medicine carried by the mist after passing through the liquid medicine is basically consistent, thereby improving the stability of the amount of medicine in the atomized mist.

[0010] In some implementations, an extension sleeve is fixedly connected to the end of the limiting block facing away from the first spring. The extension sleeve has a through cavity communicating with the through hole. The outer side wall of the extension sleeve abuts against the inner side wall of the drain pipe. The edge of the baffle is tapered. When the baffle is blocked in the through hole, its tapered side wall abuts against the inner circumferential side edge of the extension sleeve.

[0011] By adopting the above technical solution and setting an extension sleeve, the baffle can not only block the through hole, but also increase the distance between the baffle and the inner wall of the drain pipe, thereby ensuring that the filling speed of the medicine can match the usage speed of the medicine during use.

[0012] In some embodiments, the exhaust assembly includes an inlet pipe and an outlet pipe. The inlet pipe is disposed on the bottom surface of the cover, and the outlet pipe is disposed on the top surface of the cover. One end of the inlet pipe is connected to the outlet pipe, and the other end of the inlet pipe abuts against the bottom surface of the separator sleeve and is aligned with the diaphragm. A liquid inlet for flow into the diaphragm is disposed on the periphery of the inlet pipe, and an arc-shaped plate for adjusting the size of the inlet is disposed on the inlet pipe. The arc-shaped plate is slidably disposed on the side wall of the inlet pipe.

[0013] By adopting the above technical solution and setting up an air inlet pipe, the mist overflowing from the liquid medicine above the film can be directly discharged to the air outlet pipe through the air inlet pipe, thereby reducing the risk of the mist re-entering the liquid medicine for secondary mixing. Furthermore, since the air inlet pipe is in contact with the bottom surface of the separator sleeve, two independent spaces are achieved between the air inlet pipe and the medicine storage chamber. Operators can adjust the size of the liquid inlet by sliding the arc plate, thereby changing the content of the liquid medicine above the film medicine and controlling the content of the liquid medicine carried by the mist.

[0014] In some embodiments, a screw is fixedly connected to the bottom surface of the separator sleeve, the length of the screw extending toward the liquid outlet head, the top block is threadedly connected to the end of the screw toward the liquid outlet head, and the cover is also provided with a positioning component for fixing the liquid storage tank.

[0015] By adopting the above technical solution, when in use, the operator can rotate the top block to seep out a certain length along the screw length. This allows the push rod to push the baffle to extend a certain distance when the top block is on top of the push rod, thereby changing the distance between the baffle and the through hole, thus controlling the liquid inlet flow rate.

[0016] In some embodiments, the positioning component includes a telescopic block and a second spring. The cover has an insertion hole for inserting a drain pipe. The drain pipe has a groove perpendicular to its axial direction on its side wall. The telescopic block is slidably disposed in the groove. The second spring is disposed between the telescopic block and the drain pipe. The telescopic block abuts against the bottom surface of the cover.

[0017] By adopting the above technical solution, when the staff inserts the drain pipe into the insertion hole, the side wall of the insertion hole squeezes the telescopic block. Under the pressure, the telescopic block compresses the second spring. When the liquid outlet abuts against the bottom surface of the separator sleeve, the telescopic block just passes through the insertion hole. Then, under the action of the second spring, the telescopic block pushes itself out of the slide groove and abuts against the bottom surface of the cover, thereby achieving the limitation of the liquid storage tank. The liquid storage tank will not float up due to the reduction of the liquid and affect the effect of negative pressure liquid inlet.

[0018] In some embodiments, the cover has an insertion hole for inserting a drain pipe, the inner wall of the insertion hole has a threaded groove, the drain pipe has a threaded strip, and the drain pipe is screwed into the insertion hole.

[0019] By adopting the above technical solution, when the worker inserts the drain pipe into the insertion hole, rotating the storage tank causes the drain pipe to rotate, thereby screwing the drain pipe into the threaded groove on the side wall of the insertion hole on the cover. This limits the position of the storage tank, ensuring that the storage tank does not float due to the decrease of the medicine. Furthermore, when the drain pipe is screwed into the threaded groove on the insertion hole, the outlet head abuts against the bottom surface of the separator sleeve.

[0020] In some embodiments, the thin film protrudes from the bottom surface of the receiving cavity, and the upper part of the thin film has a recessed groove.

[0021] By adopting the above technical solution, when the medicine storage chamber is filled with medicine, the medicine flows into the groove of the thin film to achieve the aggregation of the medicine, thereby ensuring the amount of medicine contained in the mist when it passes through the medicine chamber.

[0022] In some embodiments, the exhaust assembly includes an air inlet duct and a fan, one end of the air inlet duct being connected to an air intake pipe, the other end of the air inlet duct being fixedly connected to the cover and extending outward from the side wall of the cover, and the fan being fixedly installed at the end of the air inlet duct located on the outside of the cover.

[0023] By adopting the above technical solution, when in use, the fan starts to ventilate the air inlet pipe. The airflow enters the air intake pipe from the air inlet pipe and is then discharged through the exhaust pipe. The flow rate of the mist is increased by setting up the fan.

[0024] In some implementations, a water level alarm is provided on the bottom surface of the receiving cavity.

[0025] By adopting the above technical solution, a water level alarm is installed in the containment cavity. When the water level is lower than the design height of the water level alarm during the atomization process, an alarm is triggered, which makes it convenient for staff to fill the containment cavity with water in a timely manner.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. This solution utilizes a negative pressure liquid inlet storage tank. The tank fills the drug storage chamber with liquid medication using the principle of negative pressure, ensuring the liquid medication in the chamber remains at a relatively constant height during use. When the atomizing plate is activated, the atomized mist overflows from the upper diaphragm through the backflow of the liquid medication, carrying the medication as it is discharged through the exhaust assembly. During this process, because the liquid medication height is essentially constant, the amount of medication carried by the mist after passing through the liquid medication is essentially uniform, thus improving the stability of the medication content in the mist atomized by the atomizer.

[0028] 2. This solution involves installing a water level alarm inside the containment chamber. When the water level drops below the designed height of the alarm during atomization, an alarm will be triggered, allowing staff to promptly refill the containment chamber with water.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0038] This application discloses an atomizing device.

[0039] Reference Figure 1 and Figure 2As shown, an atomizing device includes a cylinder 100, a cover 300, a partition sleeve 200, and a storage tank 400. The cylinder 100 has a receiving cavity 140 with an opening at the top. The partition sleeve 200 is fitted inside the receiving cavity 140 of the cylinder 100, and a thin film 150 for mist seepage is provided on the bottom surface of the partition sleeve 200. The cover 300 covers the partition sleeve 200, and the medicine storage tank is fixedly installed on the cover 300. A positioning component for fixing the medicine storage tank is provided between the medicine storage tank and the cover 300. An exhaust component for venting mist is also provided on the cover 300. A water level alarm 130, a heater 110, and two atomizing plates 120 are fixedly installed on the bottom surface of the receiving cavity 140. The two atomizing plates 120 are adjacent and parallel. The water level alarm 130 is used to detect and alarm the water level in the receiving cavity 140.

[0040] The peripheral sidewall of the separator sleeve 200 is fixedly connected with a radially extending edge, that is, the edge of the separator sleeve 200 abuts against the upper edge of the cylinder 100. The separator sleeve 200 also has an upward-opening medicine storage cavity 210, wherein there is a certain gap between the bottom surface of the separator sleeve 200 and the bottom surface of the receiving cavity 140. The lower end of the cover 300 has a downward-opening cavity, and the cavity is interconnected with the medicine storage cavity 210. Furthermore, the lower end of the cover 300 extends into the receiving cavity 140, and the upper end of the cover 300 abuts against the edge surface of the separator sleeve 200.

[0041] Reference Figure 2 and Figure 3 As shown, a drain pipe 410 for inlet and outlet of liquid is fixedly connected to the medicine storage tank, and a liquid outlet assembly is provided at the end of the drain pipe 410. A limiting tube 420 is fixedly connected to the end of the cover 300 facing the medicine storage chamber 210, and an insertion hole 301 is provided on the cover 300, through which the cover 300 and the limiting tube 420 are sequentially arranged.

[0042] Two positioning components are provided, arranged circumferentially along the drain pipe 410. Each positioning component includes a telescopic block 440 and a second spring 430. A groove 411 with an external opening is formed in the radial direction of the sidewall of the drain pipe 410. The telescopic block 440 is slidably disposed within the groove 411 along the radial direction of the drain pipe 410. The telescopic block 440 includes a sliding portion and an abutting portion. The circumferential sidewall of the sliding portion contacts the sidewall of the groove 411, and the abutting portion is fixedly connected to the sliding portion. The axial width of the abutting portion along the drain pipe 410 is smaller than that of the sliding portion. One end of the second spring 430 is fixedly connected to the sidewall of the groove 411, and the other end of the second spring 430 is fixedly connected to the side of the sliding portion opposite to the abutting portion.

[0043] The peripheral sidewall of the slide groove 411 is provided with a groove, which is connected to the slide groove 411. A block 450 is inserted into the groove. The block 450 is used to abut against the side of the sliding part facing away from the second spring 430, thereby preventing the telescopic block 440 from popping out under the action of the second spring 430.

[0044] During installation, the operator first abuts the second spring 430 against the side wall of the slide groove 411, then slides the telescopic block 440 into the slide groove 411 and compresses the second spring 430. At this time, the insert block 450 is inserted into the slot 460 to prevent the telescopic block 440 from sliding out. During use, the operator inserts the drain pipe 410 into the insertion hole 301. The side wall of the insertion hole 301 compresses the telescopic block 440. Under the pressure, the telescopic block 440 compresses the second spring 430 and retracts into the slide groove 411. When the drain pipe 410 is fully inserted into the insertion hole 301, the telescopic block 440 is no longer compressed by the side wall of the insertion hole 301 and slides out of the slide groove 411 under the action of the second spring 430, so that the abutment part abuts against the lower end of the limiting tube 420, thereby fixing the drain pipe 410.

[0045] Reference Figure 2 and Figure 4 As shown, a threaded groove is provided on the inner wall of the insertion hole 301, and a threaded strip 470 is provided on the outer wall of the drain pipe 410, with the threaded strip 470 close to the connection between the storage tank 400 and the drain pipe 410. When the medicine storage tank is installed on the cover 300, the drain pipe 410 is threadedly connected to the insertion hole 301, thereby further securing the storage tank 400.

[0046] Reference Figure 2 and Figure 4 As shown, the liquid dispensing assembly includes a dispensing head 540, a limiting block 530, and an extension sleeve 520, wherein the limiting sleeve, the limiting block 530, and the dispensing head 540 are sequentially fixedly connected. The inner cavity of the dispensing head 540 is through-holes along its axial direction, and the circumferential sidewall of the dispensing head 540 has a drain port 541 for liquid flow. The limiting block 530 has a through hole 531 that penetrates itself, and the through hole 531 communicates with the inner cavity of the dispensing head 540, and the radial width of the through hole 531 is smaller than the radial width of the inner cavity of the dispensing head 540. The extension sleeve 520 has a through cavity 521 that penetrates itself, and the through cavity 521 communicates with the through hole 531, and the radial width of the through cavity 521 is larger than the through hole 531 and smaller than the inner cavity of the dispensing head 540.

[0047] In use, the dispensing head 540 is threadedly connected to the end of the drain pipe 410 away from the storage tank 400, and the outer wall of the extension sleeve 520 abuts against the inner wall of the drain pipe 410. Furthermore, when the drain pipe 410 is fully inserted into the insertion hole 301, the end of the dispensing head 540 with the drain port 541 abuts against the bottom surface of the drug storage chamber 210.

[0048] The liquid dispensing assembly also includes a first spring 560, a push rod 550, and a baffle 510. The push rod 550 is sequentially inserted into the inner cavity of the liquid dispensing head 540, the through hole 531, and the through cavity 521. The diameter of the push rod 550 is smaller than that of the through hole 531, and the push rod 550 is T-shaped, that is, the push rod 550 is provided with a boss.

[0049] A first spring 560 is sleeved on the push rod 550, and one end of the second spring 430 abuts against the bottom surface of the inner cavity of the liquid outlet head 540, while the other end of the first spring 560 abuts against the boss. A baffle 510 is fixedly connected to the end of the push rod 550 away from the boss, and the diameter of the baffle 510 is smaller than the inner diameter of the drain pipe 410, with a tapered edge. When the push rod 550 is pulled to move under the action of the first spring 560, the tapered sidewall of the baffle 510 abuts against the inner circumferential sidewall edge of the extension sleeve 520 and seals the through cavity 521, thereby ensuring the outflow of liquid from the storage tank 400.

[0050] Reference Figure 2 and Figure 5 As shown, the liquid dispensing assembly also includes a screw 570 and a top block 580. The screw 570 is fixedly connected to the bottom surface of the partition sleeve 200, and the length direction of the screw 570 is perpendicular to the bottom surface of the partition sleeve 200. The screw 570 is located directly below the drain pipe 410 after it is inserted into the insertion hole 301. The top block 580 has an end that is sleeved on the screw 570 away from the partition sleeve 200 and is threadedly connected to the screw 570. The extension distance of the top block 580 can be changed by turning the screw connection between the top block 580 and the screw 570.

[0051] In use, when the drain pipe 410 is fully inserted into the insertion hole 301, the boss abuts against the top block 580, and under the pressure of the top block 580, it pushes the first spring 560 to compress, and the push rod 550 drives the baffle 510 to move and disengage from the passage cavity 521. Thus, the liquid medicine in the storage tank 400 passes sequentially through the drain pipe 410, the gap between the baffle 510 and the drain inner pipe, then through the passage cavity 521, the through hole 531, and the inner cavity of the outlet head 540, and finally flows into the medicine storage chamber 210 through the drain port 541. When the height of the liquid medicine is higher than the height of the drain port 541, filling of the medicine storage chamber 210 ceases.

[0052] Reference Figure 6 and Figure 7As shown, the exhaust assembly includes an inlet pipe 340 and an outlet pipe 310. The outlet pipe 310 is located above the cover 300 and extends horizontally with a bend. The inlet pipe 340 is fixedly connected to the bottom surface of the cover 300 and communicates with the outlet pipe 310. When the cover 300 is installed on the partition sleeve 200, the inlet pipe 340 abuts against the bottom surface of the drug storage chamber 210 and covers the top of the diaphragm sheet 150. This allows the mist overflowing from the diaphragm sheet 150 to flow directly from the inlet pipe 340 to the outlet pipe 310.

[0053] The side wall of the air inlet pipe 340 is provided with a liquid inlet 343 in a direction parallel to the bottom surface of the drug storage chamber 210, wherein the height of the liquid inlet 343 is lower than the height of the liquid outlet 541.

[0054] The exhaust assembly also includes an arc-shaped plate 350, a guide block 370, and a pusher block 360. A guide groove 342 is formed on the inner wall of the intake pipe 340 along its circumferential direction, located directly above the liquid inlet 343. The guide block 370 is fixedly connected to the arc-shaped plate 350 and slidably positioned along the length of the guide groove 342. A guide groove 341 is also formed on the intake pipe 340, penetrating its circumferential sidewall, with the height of the guide groove 341 higher than the height of the liquid outlet 541. The pusher block is fixedly connected to the arc-shaped plate 350 and passes through the guide groove 341 from the inside of the intake pipe 340.

[0055] In use, the operator pushes the pusher block to slide along the guide groove 341, thereby driving the arc plate 350 to move. Under the restriction of the guide block 370, the arc plate 350 moves along the guide groove 342, thereby changing the size of the liquid inlet 343 and controlling the liquid inlet rate.

[0056] The diaphragm 150 protrudes from the bottom surface of the receiving cavity 140, and a groove 160 is recessed on the upper part of the diaphragm 150. When the separator sleeve 200 is installed on the cylinder 100, the diaphragm 150 is aligned with the atomizing plate 120 and located directly above the atomizing plate 120. When the liquid medicine flows into the air inlet pipe 340 from the liquid inlet 343, it fills the groove 160.

[0057] Reference Figure 6 and Figure 7 As shown, the exhaust assembly also includes an air inlet pipe 320 and a fan 330. The air inlet pipe 320 is fixedly connected to the cover 300 and is horizontally arranged. One end of the air inlet pipe 320 is connected to the air inlet pipe 340, and the other end of the air inlet pipe 320 extends horizontally to the outside of the cover 300. The fan 330 is fixedly connected to one end of the air inlet pipe 320 outside the cover 300. In use, the fan 330 draws air from the outside and fills the air inlet pipe 340, thereby accelerating the discharge of mist from the exhaust pipe 310.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
