Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to an atomizer. Background Technology

[0002] Nebulization therapy involves converting specific medications into inhalable aerosol particles using specialized instruments or equipment. These particles are then delivered to the affected area through respiration, ultimately treating diseases of the nasopharynx, respiratory system, and other areas. Common nebulizers include compressor nebulizers, ultrasonic nebulizers, and micro-mesh nebulizers. Micro-mesh nebulizers are favored by families, hospital outpatients, and even ICU patients due to their low operating noise and minimal interference with drug activity. Their working principle involves high-frequency vibration of the core component, the atomizing plate, after being powered on. The medication is continuously sieved through micropores in the central area of ​​the atomizing plate, forming inhalable aerosol particles.

[0003] Due to the working principle and usage of the micro-mesh nebulizer, the device can only be used within a certain angle. When the patient is tilted down or lying down at an excessive angle, the medication cannot reach the nebulizer, which will cause the nebulization to stop. The nebulizer will vibrate and burn dry, which will reduce the lifespan of the nebulizer or even damage it, leading to customer complaints.

[0004] Currently, products on the market incorporate a low-water-level detection function to address the tilt angle issue. When the tilt angle is too large and the medication separates from the nebulizer plate, the device automatically shuts off, requiring the patient to manually restart it. However, with the widespread use of micro-mesh nebulizers, for infants, young children, and critically ill patients, the inability to manually restart the device after nebulization stops due to excessive tilt angle can lead to treatment interruptions.

[0037] Reference Figures 2-4 ​As shown, the medicine cartridge unit includes a medicine cartridge 102, a cup cover 103 and a cup cover plug 104. The medicine cartridge 102 is arranged at an angle of 45° with the axis of the nozzle 101. The cup cover 103 is installed on the opening of the medicine cartridge 102 through a rotating shaft. The cup cover plug 104 is installed in the medicine adding hole above the cup cover 103. The power supply electrode 107 and the tilt detection unit 108 are arranged on the medicine cartridge 102. The open state of the cup cover 103 is shown in Figure 6 As shown.

[0038] Specifically, the power supply electrode 107 is provided with two ends. One end is used to connect with the two PIN points on the atomizing piece 106 through wires respectively. The other end penetrates the lower part of the medicine cartridge 102 and is connected with the power supply connector 201. The power supply electrode 107 is fixed in the first power supply interface 110 of the medicine cartridge 104 by using the in-mold injection process. This reduces the assembly process, reduces labor costs, and reduces the risk of internal water ingress leading to short circuit.

[0039] As shown, Figure 4 The tilt detection unit 108 is installed above the first power supply interface 110. As shown, Figure 5 The tilt detection unit 108 includes an interface shell 113, a sliding rail electrode 111 and a ball electrode 112 arranged in the interface shell 113. The detection connector 202 is connected with the interface shell 113, and the interface shell 113 can be connected with the detection connector 202 from the outside. Specifically, the sliding rail electrode 111 includes a ring-shaped metal track and a detection electrode at the tail end of the ring-shaped metal track. The ball electrode 112 includes a ball 114 and a fixed rod electrode 115. The ball 114 can rotate and move around the fixed point.

[0041] In this embodiment, the PCB board 208 is a PCB board with power supply, current detection and power on detection functions, which can be purchased.

[0042] As shown, Figure 7 In another embodiment, the PCB board 208 is connected with a buzzer 209.

[0043] As shown, Figure 8As shown, in another embodiment, the PCB board 208 is connected with indicator lights, specifically, the indicator lights include a power light 212, an abnormal warning light 213, a short-time working light 214 and a long-time working light 215.

[0044] The working process of the above-mentioned atomizer is as follows:

[0045] After the power is turned on, the atomizing piece vibrates at high frequency, the liquid medicine contacts the atomizing piece and is filtered out from the center perforated area thereof, forming inhalable medicine mist particles. When the rear inclination angle of the medicine cup is too large, the liquid medicine flows backward and cannot contact the liquid medicine, causing the atomizing piece to dry burn. The current of the atomizing piece in contact with the liquid medicine under normal working condition and the current of the atomizing piece not in contact with the liquid medicine under dry burning condition are different, so that the host detects the difference, and then judges that the medicine cup is in a dry burning state, realizing the first detection function. The detection function is a function possessed by the existing atomizer. The host supplies power to the atomizing piece to make it work, and at the same time, the host can also monitor the circuit current.

[0046] The device increases the medicine cup inclination angle detection function. The medicine cup upper inclination angle detection unit is internally provided with a sliding ball, as shown in Figure 9 When the medicine cup is placed flat, the ball 114 is affected by gravity and vertically contacts the annular metal track of the slide rail electrode 111, so that the slide rail electrode 111, the ball electrode 112 and the detection connector 202 are conducted, the host collects the power-on signal and works normally, as shown in Figure 9 When the medicine cup is inclined forward or the rear inclination angle is less than the set angle, according to the angle and length of the annular metal track, the ball 114 slides forward but can still contact the slide rail electrode 111, as shown in Figure 9 When the rear inclination angle of the medicine cup is greater than the set angle, the ball is separated from the slide rail electrode under the influence of gravity, as shown in Figure 9 The detection circuit is disconnected, the host collects the information to determine that the inclination angle is too large, and automatically shuts down, establishing the second detection function; when the medicine cup is adjusted to be not inclined or inclined at the set angle, the ball recontacts the slide rail electrode 111, facilitating the control host to restart.

[0047] Under the above-mentioned two detection functions, the device not only has the function of judging whether the medicine cup is dry burning, but also can further judge whether the dry burning is caused by the inclination of the medicine cup, and timely reminds the patient to reduce the use of the inclination angle and timely restore the state for atomization treatment.

It should be understood that those skilled in the art can make many modifications and changes without creative work according to the concept of the present application.
