The utility model provides a spraying device 100, its spraying operation process is more convenient, humanized and accord with actual nasal cavity spraying and use the scene. The user need not to press spraying assembly 20 with traditional mode again, only need form the low pressure state that is less than standard atmospheric pressure in making gas channel 11 through the mode of breathing in, can make pressure-sensitive element 40 drive adjusting part 30 and move in liquid storage chamber 15 to change the stock solution volume of liquid storage chamber 15 and extrude the medicament to spraying channel 21 in and discharge. The spraying operation mode can generate the effect of simulating the absorption of the medicament by a user, and the defect that the medicament cannot be accurately sprayed into the nostril when the spraying component 20 is pressed is avoided, so that the medicament can more accurately enter the nostril, and the medicament waste is prevented; moreover, the spraying device 100 is more labor-saving in operation, can relieve the feeling of soreness and distension caused by hand pressing, and is suitable for popularization and application in nasal spray products.

The use and operation of the spray device 100 is explained in further detail below.

Firstly, a user holds the spraying device 100 by hand, the tail end of the spray head part 12 is aligned to a nostril needing to be treated by the medicament, and then the user inhales to suck out the gas in the gas channel 11 of the bottle body 10, so that the gas pressure of the gas channel 11 is reduced and a negative pressure state lower than the normal atmospheric pressure is formed;

the negative pressure state of the gas channel 11 reduces the pressure acting on the first end of the pressure sensing element 40, at the moment, the pressure of the second end is greater than that of the first end, the atmospheric pressure pushes the second end of the pressure sensing element 40 to move towards the direction of the side where the first end is located, and the second end is in contact with the connecting piece until the connecting piece conducts the power supply element and the driving element 51, so that the electric control driving assembly is started to operate;

the output shaft of the driving element 51 drives the transmission shaft 61 and the fixed fitting member 62 to rotate, and the adjusting assembly 30 forms a spiral motion centering on the axis of the reservoir 15 under the rotation of the fixed fitting member 62 and the guiding action of the threaded hole in the cover member 14, and moves towards the side close to the spraying assembly 20 and the spraying channel 21. In the process, the volume of the reservoir 16 in the reservoir 15 on the side of the seal opposite to the spray channel 21 is reduced and the internal pressure is increased, so that the medicament is squeezed into the spray assembly 20 and forms high-speed atomized droplets under the action of the spray channel 21, and the atomized droplets are sprayed into the nostrils of the user. As long as the user continuously inhales, the pressure sensing element can keep the state of abutting against the connecting piece, so that the connecting piece is always kept in the electric connection state with the power supply element and the driving element;

and (IV) under the condition of multiple uses of a user, the adjusting assembly finally moves and abuts against the spraying assembly 20, at the moment, the inner space of the liquid storage cavity 16 is in the minimum limit state, all the medicaments are discharged, the adjusting assembly 30 abuts against the contact element 81, so that the prompting electric circuit of the prompting assembly is conducted, and the light-emitting element emits light.

The features of the above-described embodiments may be arbitrarily combined, and for the sake of brevity, all possible combinations of the features in the above-described embodiments are not described, but should be construed as being within the scope of the present disclosure as long as there is no contradiction between the combinations of the features.

It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be taken as limiting the present invention, and that suitable modifications and variations of the above embodiments are within the scope of the invention as claimed.
