Referring to fig. 1 to 6, embodiments of the present invention provide a high pressure air capsule 100, and a spray device 10 and a spray assembly 20 including the same.

Specifically, the high pressure air capsule 100 provided by the embodiment of the present invention includes a capsule housing 110, a first cavity 120 located in the capsule housing 110 and adapted to contain a reagent, a second cavity 130 located in the capsule housing 110 and adapted to contain high pressure air, and movable valves 151, 152 located in the capsule housing 110 and adapted to communicate the first cavity 120 and the second cavity 130, and at least partially disposed in the capsule housing 110 and adapted to communicate or close the connection channels 141, 142.

In a specific implementation, the first cavity 120 is provided with a nozzle 121 communicating with the outside of the capsule housing 110. The movable valves 151, 152 are adapted to be moved by a force applied from the outside of the capsule housing 110 to open the connecting passages 141, 142 and allow the high pressure air to enter the first chamber 120 from the second chamber 130, so that the high pressure air drives the reagent in the first chamber 120 to be ejected from the nozzle 121 in a linear jet manner.

In a specific implementation, the capsule housing 110 has elasticity at its portion connected to the movable valves 151, 152.

In particular, the capsule housing 110 may comprise a mounting portion adapted to mount the movable valve 151, 152. The mounting portion is used to fix the movable valves 151, 152 and has elasticity adapted to be elastically deformed by a force applied from the outside of the capsule housing 110 and to be restored to the elastic deformation when the force is removed to move the movable valves 151, 152 in opposite directions to close the connection passages 141, 142.

Referring to fig. 2, in some embodiments, the movable valves 151, 152 may include a first movable valve 151. The mounting portion may include a first mounting portion having an elastic deformation capability. The first movable valve 151 passes through the first mounting portion with one end 151a thereof exposed to the outside of the capsule housing 110 and the other end 151b thereof located inside the capsule housing 110.

In some embodiments, the first movable valve 151 may be made of an elastic material and be integrally formed with the first mounting portion.

In a specific implementation, the other end 151b of the first movable valve 151 located inside the capsule housing 110 is adapted to close the connection channels 141, 142 between the first cavity 120 and the second cavity 130. For example, the other end 151b of the first movable valve 151 may be located inside the connection paths 141, 142 to close the connection paths 141, 142.

In some embodiments, the connection channels 141, 142 may include a first connection channel 141. The inner diameter of the first connection passage 141 may be gradually reduced in a direction in which the first movable valve 151 is directed to the first chamber 120. The other end 151b of the first movable valve 151 may adopt a ball type structure and be adapted to be inserted into the first connection path 141 in a direction in which the first movable valve 151 is directed to the first chamber 120 to close the first connection path 141.

Accordingly, the force applied to the first movable valve 151 from the outside of the capsule housing 110 may extend in a direction away from the first connection channel 141. Since the one end 151a of the first movable valve 151 is exposed to the outside of the capsule housing 110, the one end 151a of the first movable valve 151 is adapted to be applied with the force from the outside of the capsule housing 110. When the one end 151a of the first movable valve 151 is applied with the force, it may move in a direction away from the first connection path 141 and bring the other end 151b of the first movable valve 151 to move in a direction away from the first connection path 141 under the driving of the force. When the other end 151b of the first movable valve 151 moves from the first connection path 141 in a direction away from the first connection path 141, it may move out of the first connection path 141 to allow communication between the first chamber 120 and the second chamber 130 through the first connection path 141.

Since the first mounting portion is fixedly connected to the first movable valve 151 and has elasticity, when the first movable valve 151 is applied with an acting force to move in a direction departing from the first connection path 141, the first mounting portion may be deformed to extend in a direction departing from the first connection path 141.

When the force applied from the outside of the capsule housing 110 to the one end 151a of the first movable valve 151 is removed, the first mounting portion is restored to be elastically deformed and drives the first movable valve 151 to move in the opposite direction, thereby moving the other end 151b of the first movable valve 151 in a direction toward the first connection path 141 to be inserted into and close the first connection path 141.

Referring to fig. 3, in other embodiments, the movable valves 151, 152 may include a second movable valve 152. The mounting portion may include a second mounting portion having an elastic deformation capability. The second movable valve 152 is located in the capsule housing 110, and one end 152a thereof is fixed to the second mounting portion.

In some embodiments, the second mounting portion may be of a resilient material and be integrally formed with the capsule housing 110.

In a specific implementation, the other end 152b of the second movable valve 152 is adapted to close the connecting channels 141, 142 between the first chamber 120 and the second chamber 130. For example, the other end 152b of the second movable valve 152 may be located within the connection channel 141, 142 to close the connection channel 141, 142.

In some embodiments, the connection channels 141, 142 may include a second connection channel 142. The second connection passage 142 has an inner diameter smaller at one end communicating with the second chamber 130 than at the other end thereof. Accordingly, the other end 152b of the second movable valve 152 may take a ball type structure and have a matched outer diameter of the other end of the second connection path 142. The other end 152b of the second movable valve 152 may be inserted into the other end of the second connection path 142 to close the second connection path 142. Meanwhile, the second movable valve 142 may employ a rod-shaped structure having a diameter smaller than that of the ball-shaped structure at a portion thereof where the ball-shaped structure is removed. And, the diameter of the rod-shaped structure is smaller than or equal to the inner diameter of one end of the second connection passage 142. The rod-like structure may be fixedly mounted to the second mounting portion through one end of the second connection passage 142.

In a specific implementation, the force applied to the second mounting portion from the outside of the capsule housing 110 may extend in a direction toward the second connection channel 142. When the second mounting portion is applied with the force from the outside of the capsule housing 110, the second mounting portion may be elastically deformed by the force and move one end 152a of the second movable valve 152 in the direction toward the second connection channel 142, and thus move the other end 152b of the second movable valve 152 in the direction toward the second cavity 130 communicating with the second connection channel 142. When the other end 152b of the second movable valve 152 moves toward the second chamber 130, it can move out of the second connection channel 142 and move into the second chamber 130, thereby communicating between the first chamber 120 and the second chamber 130 through the second connection channel 142.

When the force applied to the second mounting portion is removed, the second mounting portion will recover the elastic deformation and drive the second movable valve 152 to move in the opposite direction, so that the other end 152b of the second movable valve 152 returns to the second connecting channel 142 to close the second connecting channel 142.

When the first chamber 120 and the second chamber 130 are communicated through the connecting channels 141 and 142, the high-pressure air in the second chamber 130 can enter the first chamber 120 from the second chamber 130, so as to drive the reagent in the first chamber 120 to be ejected from the nozzle 121 in a linear jet manner.

In some embodiments, the reagent may comprise a powdered reagent. In this case, the linear jet ejected from the nozzle 121 may include a powder jet.

In other embodiments, the reagent may also include a liquid reagent. In this case, the linear jet ejected from the nozzle 121 may include a liquid jet.

It will be appreciated that in implementations, the particle size of the liquid or powder in the linear jet may also be controlled by controlling the pressure of the high pressure air and/or the orifice size of the nozzle 121.

In some embodiments, the liquid jet may comprise a liquid jet in an atomized state having a particle size that is the same as or similar to the particle size of the reagent after atomization. Thus, the reagent can be sprayed out to have a spraying effect.

In other embodiments, the liquid spray may comprise a non-atomized spray having a larger particle size than an atomized spray. In this way, the reagent can be ejected with a long range, and thus, the reagent can be supplied at a long distance, that is, deep drug administration can be performed well.

In some embodiments, the first cavity 120 further has a first cavity opening communicating with the outside and a cover 122 disposed at the first cavity opening. The nozzle 121 may be disposed on the cover 122.

In a specific implementation, the first cavity 120 and the second cavity 130 may be in communication with each other, and air may be delivered into the first cavity 120 through the first cavity opening to deliver air into the second cavity 130 and form high pressure air in the second cavity 130. When high-pressure air is formed in the second chamber 130, the movable valves 151 and 152 may close the space between the first chamber 120 and the second chamber 130, thereby sealing the high-pressure air in the second chamber 130.

When the second chamber 130 is filled with high pressure air, the reagent can be transferred into the first chamber 120 through the first chamber opening, and the first chamber opening is closed by the cover 122 after the reagent is transferred.

The second chamber 130 may enclose a high pressure gas other than air, while ensuring safe use.

In one embodiment, the nozzle 121 disposed on the cover 122 has a very small diameter, which is not enough to discharge the reagent out of the capsule housing 110 without being driven by high pressure air.

In some embodiments, the high pressure air capsule 100 may be a disposable, disposable capsule. In this case, the high pressure air introduced into the first chamber 120 from the second chamber 130 is suitable for ejecting the reagent in the first chamber 120 all at once.

Referring to fig. 1 to 3, an embodiment of the present invention further provides a spraying device 10.

Specifically, the spray device 10 may include a device housing 200, a high pressure air capsule 100 located within the device housing 200, and a trigger mechanism 300 secured within the device housing 200.

In some embodiments, one end 321 of the movable member 320 is adapted to be pressed to rotate the other end 322 thereof in a direction away from the first connection path 141, so as to apply a force to the one end 151a of the first movable valve 151, which extends in a direction away from the first connection path 141.

In other embodiments, the one end 321 of the movable member 320 is further adapted to be pressed to rotate the other end 322 thereof in a direction toward the second connection path 142, so as to apply a force to the one end 152a of the second movable valve 152 extending in the direction toward the second connection path 142.

In the embodiment of the present invention, the triggering mechanism 300 may be implemented by any conventional technical means known in the prior art, which is not limited herein.

In an implementation, the device housing 200 includes a capsule cavity 210 and an access port 220 communicating the capsule cavity 210 with the outside. The high pressure air capsule 100 is loaded into the capsule cavity 210 or unloaded from the capsule cavity 210 through the pick-and-place port 220.

In some embodiments, the high pressure air capsule 100 is adapted to have an interference fit with the capsule cavity 210 when loaded into the capsule cavity 210.
