Description

Spray can

This creation is about spray cans, especially a spray can with improved flow paths.

A spray can is a respiratory treatment medical device for atomizing a medical solution and mixing air for inhalation by a patient. The construction of the spray can generally includes a nozzle disposed within a body of the cup, an impact surface, and a cover. The cone cover covers the impact surface, the nozzle provides high-pressure airflow, and the liquid medicine is atomized by the high-pressure airflow and the liquid medicine is impacted on the impact surface, and is mixed with air to form a medicine mist. The mist is guided by the cone and turned back to the flow and passes over the sides of the nozzle thereby extending the flow distance of the mist within the cup to allow for more uniform mixing. The space between the cone of the existing spray can and the side of the nozzle is narrowed, so that the flow of the mist is blocked. If the flow space of the mist is increased by providing a larger cone, the volume of the cup must be increased enough to accommodate the cone. The cover, but the volume of the spray can is too large, resulting in inconvenient use.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

This creation provides a spray can with an improved flow path.

The spray can of the present invention increases the expansion ratio of the two ends of the cone cover by the design of the curved cone cover, so that the flow field resistance can be reduced without increasing the volume of the cone cover.

Referring to Fig. 1, a preferred embodiment of the present invention provides a spray can for atomizing a mixed liquid of a liquid. The spray can of the present invention comprises a cup 100, an atomizing nozzle 200 and an intake pipe 300.

Referring to FIGS. 2 to 5, the top of the cup holder 100 is formed with an opening 101, and the side of the cup holder 100 is formed with an outlet 102. A pressure nozzle 110 extends from the bottom surface of the cup holder 100. The pressure nozzle 110 has a tapered shape. The tip end of the pressure nozzle 110 has an opening 111 and faces the opening 101. The outer surface of the root of the pressure nozzle 110 is convex. There are a plurality of ribs 112 arranged around the pressure nozzles 110, and each of the ribs 112 extends in the longitudinal direction of the pressure nozzle 110, respectively. The bottom outer surface of the cup holder 100 extends out of a socket 120 that extends through the bottom of the cup holder 100 to communicate with the root of the pressure nozzle 110.

Referring to Figures 5-7, the atomizing nozzle 200 is tapered and has a tip 201 at its tip end. The two ends of the intake pipe 300 are respectively an inner end 301 and an outer end 302. The inner end 301 of the intake pipe 300 is provided with an impact block 310 and a cone cover 400. The tip end of the atomizing nozzle 200 faces the impact block 310. The impingement block 310 and the atomizing nozzle 200 are connected to the inner end 301 of the intake pipe 300 by at least one connecting plate 320. In this embodiment, the connecting plate 320 is preferably a pair, but The creation does not limit the number of connection plates 320. The outer end 302 of the intake pipe 300 extends outwardly from the outer side to form a cap 330, and the outer edge of the cap 330 is formed with a ring rib 331.

The cone cover 400 is a curved cone that extends outwardly, and its curved surface is preferably curved outward. The tip end of the cone cover 400 extends out of a pair of hooks 410 that penetrate the inner end 301 of the intake pipe 300 and snap into the inner wall of the inner end 301 of the intake pipe 300 such that the cone cover 400 is self-intake The tube 300 extends toward the atomizing nozzle 200 in an expanded curved surface. The tip end of the cone cover 400 communicates with the intake pipe 300, and the cone cover 400 covers the impact block 310 and the tip end of the atomizing nozzle 200. A baffle 340 extends from the outer side of the intake pipe 300, and the baffle 340 is disposed along the lateral direction of the intake pipe 300. A through slot 420 is defined in each of the connecting plates 320. The through slot 420 extends in the longitudinal direction of the cone cover 400. The connecting plate 320 is inserted into the corresponding slot 420 to position the cone cover 400 so as to be unable to rotate. The edge of the end of the cone cover 400 is respectively provided with a connecting structure 421 spanning the slot 420 corresponding to each of the slots 420, thereby reinforcing the structure of the cone cover 400. Moreover, a stopper 321 corresponding to the snap connection structure 421 is protruded from the edge of each connecting plate 320, thereby preventing the cone cover 400 from coming off.

Referring to FIG. 2 to FIG. 5, the intake pipe 300 is inserted into the cup holder 100 through the opening 101 of the cup holder 100, and the bottle cover 330 covers the opening 101 of the cup holder 100, and the ring rib 331 abuts the cup. The inner wall of the seat 100 thereby seals the opening 101. Therefore, the impact block 310 is housed in the cup holder 100.

2, 3 and 8, the atomizing nozzle 200 is sleeved outside the pressure nozzle 110, and each of the ribs 112 abuts against the inner wall of the atomizing nozzle 200 to pressurize the nozzle 110 and the atomizing nozzle 200, respectively. Interval configuration. The deflector 340 is interposed between the pressurized nozzle 110 and the outlet 102, and the deflector 340 extends to abut against the inner wall of the cup holder 100.

Referring to FIG. 2 and FIG. 3, when the spray can of the present invention is used, the bottom of the cup holder 100 is used for containing the liquid medicine and the root of the atomizing nozzle 200 is immersed in the liquid medicine, and the connecting pipe 120 is connected with a high-pressure gas source to thereby apply high-pressure gas. The source is introduced into the pressurized nozzle 110. The gas flows out at a high speed through the opening 111 at the tip end of the pressurizing nozzle 110 to form a negative pressure at the tip opening 201 of the atomizing nozzle 200, thereby driving the chemical liquid to flow through the gap between the pressurizing nozzle 110 and the atomizing nozzle 200 to the mist. At the tip opening 201 of the nozzle 200, external air is driven to flow into the cup holder 100 through the intake pipe 300. The liquid medicine is ruptured into the fine particles at the tip opening 201 of the atomizing nozzle 200 and accelerated by the high-speed airflow to hit the impact block 310, and the fine chemical liquid particles are mixed with the inflowing air to form a medicine mist. After the high-speed airflow hits the impact block 310, it is turned back along the cone cover 400, and it drives the medicine mist to the outlet 102 of the cup holder 100, and the medicine mist is blown out through the outlet 102 of the cup holder 100 for inhalation by the patient. The baffle 340 is interposed between the pressurized nozzle 110 and the outlet 102 to block the mist, thereby extending the flow distance of the mist in the cup 100 so that the liquid particles can be more uniformly mixed with the air.

Referring to FIG. 9, the edge of the cone cover 400 can be selectively provided with a notch 430 to reduce the resistance generated by the cone cover 400, thereby increasing the flow rate of the air introduced into the intake pipe 300.

The spray can of the present invention has a cone cover 400 with a curved cone extending outwardly, and the expansion ratio of the two ends of the cone cover 400 is larger than that of the linearly extending cone, so that the volume of the cone cover 400 can be increased without being enlarged. A larger space is formed at the periphery of the nozzle 200 for the mist to flow, whereby the flow field resistance can be reduced.
