Description

  The present invention relates to a structure of a sprayer, and more particularly, to a sprayer provided with a rotationally connected medical cup.

  As medical technology advances, medical nebulizers are being researched and developed in the market so that patients can absorb drugs more fully and easily. This nebulizer achieves the purpose of accelerating treatment by atomizing a liquid medicine and delivering the atomized medicine into a patient's oral cavity through a route or a spout. Therefore, the nebulizer is now one of the common medical devices.

  Conventional atomizers are roughly classified into an ultrasonic atomizer and an air compression atomizer. An ultrasonic nebulizer atomizes a chemical solution using an ultrasonic principle. On the other hand, in the case of an air compression type sprayer, a high-speed air current is formed by allowing compressed air to pass through a narrow nozzle. A liquid or other fluid is jetted onto the shielding object by the negative pressure generated thereby, and collides at high speed and scatters to the surroundings, so that the droplets are atomized and ejected from the exhaust pipe.

  However, regardless of whether it is an ultrasonic atomizer or an air compression atomizer, it is essential to replace the medical cup. However, many current nebulizers use slide-type medical cup replacement, and there is a problem that it is difficult to replace the medical cup because a space for sliding the medical cup must be secured in advance. It was. Therefore, one of the points of improvement in the nebulizer industry is that the medical cup can be replaced smoothly even in a narrow space.

  Since the medical cup is exchanged in a rotating manner, the present invention has a rotating connection type medical cup that has the advantage that the medical cup can be exchanged smoothly even in a narrow space and the medical cup is easy to exchange. Provide a nebulizer.

  In the embodiment, the present invention has a mounting surface, a plurality of arc-shaped convex ribs extending from the mounting surface, and a first engagement piece extending to one side of each arc-shaped convex rib, A plurality of arc-shaped grooves are provided so as to be rotatable with respect to the mounting surface and detachably connected to the mounting surface, and a plurality of second members provided on one side of each of the arc-shaped grooves. The combined piece extends, and an inclined surface is provided on the upper portion of each second engagement piece, and each arc-shaped convex rib is inserted into each arc-shaped groove so as to be slidable. A nebulizer is provided that includes a switchable medical cup including a medical cup with a piece engageable with each of the inclined surfaces.

  Based on the above, one dimension of the plurality of first engagement pieces is larger than the dimension of the remaining one of the plurality of first engagement pieces, and one dimension of the plurality of notches is a plurality of notches. It is larger than the dimensions of the rest of the notches. Since the first engaging piece having a large dimension is set to be able to be inserted only into a notch having a large dimension, the medical cup can be reliably mounted on the mounting surface by a predetermined method. Therefore, the medical cup of the sprayer is provided with a Pokayoke mechanism in assembly.
