Description

Technical Field

[0001] The present invention relates to the technical field of sprayers, and particularly to a throat sprayer. Background Art

[0002] A throat sprayer is a device specifically used for spraying drugs in the throat area (including the uvula, larynx, and pharynx). It is usually used to treat throat diseases such as laryngitis, pharyngitis, tonsillitis, sore throat, etc. By atomizing the liquid medicine into fine particles, the sprayer can cover and penetrate deep into the throat, helping the medicine to exert its effect more efficiently.

[0003] The prior art document with the publication number CN118767311A provides a sprayer for ENT care. This technology not only facilitates spraying medicine on the affected area of the oral cavity and throat, but also expands and supports the upper and lower jaws near the oral cavity and throat through an expansion member, which is beneficial for fully spraying medicine on the affected area of the oral cavity and throat, avoiding the situation that the spray head of the existing sprayer is limited by the occlusion of the upper and lower jaws, resulting in difficulty in fully spraying the medicine onto the inflamed area; at the same time, only one stepper motor needs to work to simultaneously perform the two actions of the stirring paddle oscillating the liquid medicine up and down and stirring the liquid medicine forward and backward, avoiding the situation that the efficacy of the medicine is affected due to the sinking of the liquid medicine after spraying, making the efficacy of the medicine after spraying better.

[0004] The prior art has achieved spraying on the throat. The uvula is located above the posterior part of the larynx and is relatively deep. The spray angle of the existing throat sprayers is usually fixed, and it is difficult to accurately reach the area behind the uvula. Even if the angle of the sprayer is adjusted, the spray is likely to not directly cover this area, resulting in the medicine being unable to effectively reach the ulcer area and affecting the treatment effect.

[0005] In summary, although the prior art can achieve spraying on the throat, there is a lack of an effective spraying technology that can accurately target the uvula, especially the area behind the uvula. Summary of the Invention
