[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-5As shown, a child emergency breathing device with humidification function includes an air inlet cylinder 1, an upper liquid seat 2 threadedly installed at the top of the air inlet cylinder 1, an air jet pipe 4 fixedly connected to the middle of the top of the upper liquid seat 2, an air inlet pipe 3 fixedly connected to the middle of the top of the air inlet cylinder 1, an atomizing mechanism 6 provided in the inner cavity of the air inlet cylinder 1, and a liquid dispensing mechanism 5 provided in the inner cavity of the upper liquid seat 2.

[0022] In the implementation of this solution, one end of the air inlet pipe 3 is connected to the output end of the ventilator, and one end of the jet pipe 4 is connected to the breathing mask. The ventilator introduces oxygen into the inner cavity of the air inlet cylinder 1 through the air inlet pipe 3, and then blows to lift the liquid dispensing mechanism 5 at the bottom of the upper liquid seat 2. The liquid dispensing mechanism 5 guides the liquid medicine in the upper liquid seat 2 to drip onto the nebulizing mechanism 6 in the inner cavity of the air inlet cylinder 1 for nebulization. In this way, when the ventilator is working, it not only provides oxygen to the patient, but also supplies the nebulized liquid medicine to the patient at the same time, realizing effective drug treatment while supplying oxygen.

[0023] Specifically, the atomizing mechanism 6 includes four vertical rods 61 and a compound spring 54. The four vertical rods 61 are arranged in a rectangular array and installed on the bottom wall of the inner cavity of the air inlet cylinder 1 away from its axis. The air inlet hole 64 is opened through the bottom wall of the inner cavity of the air inlet cylinder 1 at the axis. The air inlet pipe 3 is connected to the inner cavity of the air inlet cylinder 1 through the air inlet hole 64.

[0024] The tops of the four vertical rods 61 are fixedly connected to a liquid-gathering hopper 62. The liquid-gathering hopper 62 is a cone shape that is wider at the top and narrower at the bottom. The upper part of the outer surface of the liquid-gathering hopper 62 is fixedly connected to the inner cavity of the air inlet cylinder 1. A fixing seat 621 is fixedly installed at the middle of the bottom end of the liquid-gathering hopper 62. An ultrasonic atomizer 622 is fixedly installed in the inner cavity of the fixing seat 621. The output end of the ultrasonic atomizer 622 passes through the inner cavity of the liquid-gathering hopper 62. Multiple air guide tubes 63 are installed in a ring array through the middle of the outer surface of the liquid-gathering hopper 62.

[0025] After the ventilator delivers oxygen into the inner cavity of the air intake 1 through the air intake tube 3, the oxygen in the air intake 1 is blocked by the liquid collection hopper 62 and gathers on the lower side of the inner cavity of the air intake 1. It is then guided and blown towards the axis on the upper side of the inner cavity of the air intake 1 through multiple liquid storage chambers 53. Due to the small diameter of the multiple air guide tubes 63, according to the law of conservation of energy, the oxygen flow velocity increases when the multiple air guide tubes 63 blow out oxygen. The increased oxygen flow blows upwards, causing the liquid lowering mechanism 5 to drip the medicine in the inner cavity of the upper liquid seat 2 into the inner cavity of the liquid collection hopper 62 during the upward pushing process. The medicine is then atomized by the ultrasonic nebulizer 622 in the inner cavity of the liquid collection hopper 62.

[0026] It is worth mentioning the ultrasonic nebulizer 622. The ultrasonic nebulizer 622 is existing technology, and its model number is WH-2000. Its working principle is to use ultrasonic oscillation to cause the particles on the surface of the liquid medicine to fall off and form a fine mist. As for the specific circuit installation method of the ultrasonic nebulizer 622, it will not be described in this solution.

[0027] Specifically, the liquid lowering mechanism 5 includes a separation tube 51 and two sliding holes 55. The separation tube 51 is vertically installed at the axis of the top and bottom walls of the inner cavity of the upper liquid seat 2. The separation tube 51 divides the inner cavity of the upper liquid seat 2 into two parts: an aerosol output chamber 52 and a liquid storage chamber 53. The upper and lower ends of the aerosol output chamber 52 are open. The jet pipe 4 is connected to the aerosol output chamber 52. The lower port of the aerosol output chamber 52 is connected to the inner cavity of the air inlet cylinder 1.

[0028] A bottom ring 521 is fixedly installed on the lower side of the inner surface of the aerosol output chamber 52. A top ring 522 is fixedly installed on the inner surface of the aerosol output chamber 52 above the bottom ring 521. A sealing plate 523 adapted to the sealing plate 52 is slidably installed on the inner surface of the aerosol output chamber 52. The sealing plate 523 is located between the bottom ring 521 and the top ring 522. A connecting rod 525 is installed through the top axis of the sealing plate 523. Multiple air outlet holes 524 are opened in a ring array at the top of the sealing plate 523 away from its axis.

[0029] A compound spring 54 is placed inside the aerosol output chamber 52. The two ends of the compound spring 54 abut against the top ring 522 and the sealing plate 523 respectively. The top of the connecting rod 525 is fixedly installed with a push plate 526. Two sliding holes 55 are symmetrically opened through the bottom wall of the liquid storage chamber 53 on both sides away from the axis. Two sliding rods 551 are slidably installed on the inner surface of the two sliding holes 55 respectively. The top of the two sliding rods 551 is fixedly installed with two sealing plates 553 that limit the two sliding holes 55 respectively. The lower side of the outer surface of the two sliding rods 551 is provided with a spiral liquid outlet groove 552. The bottom ends of the two sliding rods 551 are fixedly connected to the top of the push plate 526 on both sides.

[0030] When multiple air guide tubes 63 blow multiple high-velocity oxygen streams upward, the increased oxygen flow propels the top plate 526 upward. As the top plate 526 moves upward, it drives the two slide rods 551 to move vertically upward along the two sliding holes 55. When the two slide rods 551 move upward, the two sealing plates 553 at their tops come into contact, sealing the liquid storage chamber 53. This causes the liquid medicine in the liquid storage chamber 53 to drip down along the two spiral liquid outlet grooves 552 opened on the outer surface of the two slide rods 551 and onto the ultrasonic nebulizer 622 for atomization.

[0031] When the actuating plate 526 moves upward, the connecting rod 525 pushes the sealing plate 523, which is slidably installed in the aerosol output chamber 52, away from the bottom ring 521. When the sealing plate 523 releases its restriction on the bottom ring 521, the atomized gas and oxygen enter the upper side of the inner cavity of the aerosol output chamber 52 through the multiple air outlets 524 on the sealing plate 523, and are delivered to the oxygen mask through the air jet pipe 4 for the patient to inhale.

[0032] When oxygen supply is stopped, the tension of the spring 54 pushes the sealing plate 523 down to reset it, so that the sealing plate 523 re-seals the bottom ring 521. At the same time, the two sealing plates 553 will also reset to seal the two sliding holes 55, thus avoiding the waste of medicine caused by unnecessary opening and closing of the two sliding holes 55.

[0033] Furthermore, an upper liquid port 7, which communicates with the liquid storage chamber 53, is fixedly installed on the upper surface of the outer surface of the upper liquid seat 2, and a sealing cap 71 is threadedly installed at the upper port of the upper liquid port 7.

[0034] Unscrew the sealing cap 71 from the upper liquid port 7 and add the medicine into the inner cavity of the storage chamber 53 through the upper liquid port 7 for use.

[0035] It should be noted that the air inlet pipe 3 and the air jet pipe 4 used in this utility model, as well as their specific installation and connection methods with the breathing mask and ventilator, are all conventional designs, and will not be described in detail in this utility model.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
