[0002] Most of the existing breathing devices are used by the elderly. When using the breathing device, the user needs to inhale continuously and with a certain strength. The existing breathing device nozzle structure cannot be used to judge the inhalation strength during use. In addition, the medicine powder is colorless and odorless. The existing breathing device nozzle structure is silent during use. Many people always feel that they have not inhaled it, which makes the user feel uneasy. Therefore, a nozzle structure is needed;

[0003] At the same time, the existing breathing device and the suction nozzle structure are usually sealed with a sealing gasket inside the process breathing device. Due to long-term use, the sealing gasket is prone to aging, resulting in a certain gap between the suction nozzle structure and the breathing device, making the sealing between the suction nozzle structure and the breathing device poor, affecting the use of the breathing device. Summary of the invention

[0004] The utility model aims to solve the problem that the user cannot judge the inhalation strength in the above-mentioned prior art and the problem that long-term use may easily cause a gap between the breathing device and the main body of the suction nozzle structure, affecting the use of the breathing device, and provide an improved suction nozzle structure for a breathing device.

[0005] The utility model solves the technical problem by adopting a technical solution: the improved breathing device uses a nozzle structure

[0006] For further improvement, an improved nozzle structure for a breathing device is provided, comprising a nozzle structure main body and a breathing device, wherein the outer wall of the nozzle structure main body is connected to the breathing device, and a limiting structure is arranged on the left side of the nozzle structure main body, wherein the limiting structure comprises a circular ring, and the inner wall of the circular ring is fitted with the nozzle structure main body, and the middle part of the circular ring is clamped with a plurality of clamping blocks, the outer end of the clamping block is fixedly connected to the pressure block, the outer wall of the pressure block is slidably connected to the circular ring, and the inner end of the clamping block is fixedly connected to one end of a second spring.

[0007] For further improvement, the inner wall of the nozzle structure body is in contact with the cavity, and a reed is provided at the bottom of the cavity.

[0008] For further improvement, the left end of the circular ring is fixedly connected to the suction nozzle, and the middle part of the suction nozzle is fixedly connected to the cavity.

[0009] For further improvement, the other end of the second spring is fixedly connected to the nozzle structure body, and the outer wall of the clamping block is slidably connected to the nozzle structure body.

[0010] For further improvement, an auxiliary structure is provided on the right side of the nozzle structure body, and the auxiliary structure includes a sliding rod, both ends of multiple sliding rods are fixedly connected to the nozzle structure body, the left side of the outer wall of the sliding rod is slidably connected to the L-shaped rod, the inner side of the L-shaped rod is fixedly connected to one end of the first spring, the other end of the first spring is fixedly connected to the nozzle structure body, and the right ends of multiple L-shaped rods are fixedly connected to the sealing gasket.

[0011] For further improvement, the right end of the sealing pad is tightly pressed against the breathing device, and the outer walls of the plurality of L-shaped rods are slidably connected to the main body of the nozzle structure.

[0012] The beneficial effects of the utility model are as follows: the utility model, through the user inserting the cavity and the reed into the interior of the suction nozzle structure body through the suction nozzle, the suction nozzle drives the circular ring to move rightward along the outer wall of the suction nozzle structure body, so that the circular ring squeezes the clamping block to move inward, and the clamping block drives the second spring to compress. When the clamping block corresponds to the clamping groove of the circular ring, the elastic force of the second spring makes the clamping block and the circular ring clamped, so that when the user inhales the medicine through the suction nozzle, the air passes through the bottom of the cavity and is inhaled by the user. During the air flow, the reed is forced to vibrate, thereby making a sound to remind the user. When in use, if the user's breathing force is not enough, the reed will not vibrate and thus will not make a sound, thereby realizing the judgment of the user's inhalation force, making the user feel more at ease and more convenient to use;

[0013] After the nozzle structure body is connected to the breathing device, the sealing gasket contacts the arc device and is affected by the reaction force, so that the sealing gasket drives the L-shaped rod to move leftward, and the L-shaped rod drives the first spring to stretch along the sliding rod. When a gap appears between the sealing gasket and the breathing device, the first spring always acts on the L-shaped rod, so that the sealing gasket fits tightly with the breathing device when used, thereby filling the gap, improving the sealing between the breathing device and the nozzle structure body, and avoiding the problem that a gap between the breathing device and the nozzle structure body may occur due to long-term use and affect the use of the breathing device.

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Embodiment 1: refer to the attached Figure 1-4 In the present embodiment, an improved nozzle structure for a respiratory device comprises a nozzle structure body 1 and a respiratory device 2, wherein the outer wall of the nozzle structure body 1 is fitted with the respiratory device 2, and a limiting structure 4 is arranged on the left side of the nozzle structure body 1, wherein the limiting structure 4 comprises a circular ring 4a1, and the inner wall of the circular ring 4a1 is fitted with the nozzle structure body 1. The user inserts the cavity 5 and the reed 6 into the interior of the nozzle structure body 1 through the nozzle 7, so that the nozzle 7 drives the circular ring 4a1 to move rightward along the outer wall of the nozzle structure body 1, so that the circular ring 4a1 squeezes the card block 4a3 to move inward, and the card block 4a3 drives the second spring 4a4 to compress, and when the card block 4a3 corresponds to the card groove of the circular ring 4a1, the elastic force of the second spring 4a4 causes the card block 4a3 to be engaged with the circular ring 4a1, so that when the user inhales the medicine through the nozzle 7, the air is inhaled through the bottom of the cavity 5 by the user, and the reed 6 is subjected to force and vibrates during the air flow, thereby A sound is emitted to remind the user. During use, the reed 6 will not vibrate and thus will not make a sound due to insufficient breathing force of the user. When disassembling the cavity 5, the pressure blocks 4a2 on both sides are pressed inwardly, so that the clamping blocks 4a3 move inwardly and disengage from the circular ring 4a1, thereby disassembling and replacing the cavity 5 and the reed. The middle part of the circular ring 4a1 is clamped with multiple clamping blocks 4a3, the outer end of the clamping block 4a3 is fixedly connected to the pressure block 4a2, the outer wall of the pressure block 4a2 is slidably connected to the circular ring 4a1, the inner end of the clamping block 4a3 is fixedly connected to one end of the second spring 4a4, the inner wall of the nozzle structure main body 1 is fitted with the cavity 5, and a reed 6 is provided at the bottom of the cavity 5, the left end of the circular ring 4a1 is fixedly connected to the nozzle 7, the middle part of the nozzle 7 is fixedly connected to the cavity 5, the other end of the second spring 4a4 is fixedly connected to the nozzle structure main body 1, and the outer walls of the clamping blocks 4a3 are all slidably connected to the nozzle structure main body 1.

[0021] An auxiliary structure 3 is arranged on the right side of the nozzle structure main body 1. The auxiliary structure 3 includes a slide bar 301. Both ends of the slide bars 301 are fixedly connected to the nozzle structure main body 1. The left side of the outer wall of the slide bar 301 is slidably connected to the L-shaped rod 302. After the nozzle structure main body 1 is connected to the breathing device 2, the sealing gasket 304 contacts the arc device and is affected by the reaction force, so that the sealing gasket 304 drives the L-shaped rod 302 to move to the left. The L-shaped rod 302 drives the first spring 301 to stretch along the slide bar 301. When a gap appears between the sealing gasket and the breathing device 2, the first spring 301 is pulled away from the sealing gasket. A spring 303 always acts on the L-shaped rod 302, so that the sealing gasket is tightly fitted with the breathing device 2, thereby filling the gap and improving the sealing between the breathing device 2 and the suction nozzle structure body 1. The inner side of the L-shaped rod 302 is fixedly connected to one end of the first spring 303, and the other end of the first spring 303 is fixedly connected to the suction nozzle structure body 1. The right ends of multiple L-shaped rods 302 are fixedly connected to the sealing gasket 304, and the right end of the sealing gasket 304 is tightly pressed against the breathing device 2.

[0022] Working principle: the user inserts the cavity 5 and the reed 6 into the interior of the suction nozzle structure body 1 through the suction nozzle 7, so that the suction nozzle 7 drives the ring 4a1 to move rightward along the outer wall of the suction nozzle structure body 1, so that the ring 4a1 squeezes the block 4a3 to move inward, and the block 4a3 drives the second spring 4a4 to compress. When the block 4a3 corresponds to the groove of the ring 4a1, the elastic force of the second spring 4a4 makes the block 4a3 and the ring 4a1 engage with each other, so that when the user inhales the medicine through the suction nozzle 7, the air passes through the bottom of the cavity 5 and is inhaled by the user. During the air flow, the reed 6 is forced to vibrate, thereby making a sound to remind the user. When in use, if the user's breathing force is not strong enough, the reed 6 will not vibrate and will not make a sound, thereby realizing the judgment of the user's inhalation force, making the user feel more at ease and convenient to use;

[0023] After the nozzle structure body 1 is connected with the breathing device 2, the sealing gasket 304 contacts with the arc device and is affected by the reaction force, so that the sealing gasket 304 drives the L-shaped rod 302 to move to the left, and the L-shaped rod 302 drives the first spring 301 to stretch along the sliding rod 301. When a gap appears between the sealing gasket and the breathing device 2, the first spring 303 always acts on the L-shaped rod 302, so that the sealing gasket is used to fit tightly with the breathing device 2, thereby filling the gap, improving the sealing between the breathing device 2 and the nozzle structure body 1, and avoiding the problem that a gap between the breathing device 2 and the nozzle structure body 1 may occur due to long-term use and affect the use of the breathing device.
