Description

Technical Field

[0001] The present invention relates to the technical field of medical atomizers, and more specifically, to an auxiliary atomization device. Background Art

[0002] Atomization inhalation therapy is a common treatment method for children's respiratory diseases. By converting the liquid medicine into tiny particles and directly acting on the lesion through the respiratory tract, it has the advantages of quick onset and small dosage. As a core medical device, the rationality of the structural design of the auxiliary atomization device directly affects the treatment effect and user experience.

[0003] When the existing atomizer is working, it usually continuously conveys air flow into the atomization cup through the air source, atomizes the liquid medicine, and then continuously outputs it to the patient's respiratory tract through the outlet. However, such devices generally have a key defect: when a child patient exhales, the exhaled gas will form an opposite impact with the continuously input atomization gas at the outlet. That is, since the exhaled gas cannot be guided or blocked in time, the two air flows will violently mix in the outlet area, resulting in vortex and pressure disorder. During this process, the atomized liquid medicine particles will aggregate and collide due to the air flow impact, and finally converge into larger droplets, which seriously destroys the uniformity of the liquid medicine particles and thus seriously affects the absorption effect of atomization.

[0004] Therefore, in view of the above technical defect problems, it is necessary to propose an auxiliary atomization device. Summary of the Invention

[0005] The purpose of the present invention is to propose an auxiliary atomization device in view of the above technical defects. When this atomizer is in use, it can drain and guide the exhaled gas, avoid the opposite impact between the exhaled air flow and the continuously input atomization gas, and thus prevent the problem of aggregation and accumulation of the atomization gas.

When the vertical block is in the initial state, its extension rod can be aligned with the middle of the outer wall of the push block. The third spring is arranged below inside the vertical groove. The top plate is connected to the upper end of the third spring. During use, the third spring can push the top plate to move upward, and the lower surface of the vertical block also contacts the top plate. At the same time, when the push plate moves to the extreme position on the right side of the second straight groove, the resilience of the first spring is greater than the resistance generated by the third spring when it is compressed.

[0020] Preferably, the left side of the movable tube is of a closed structure, while the right side is of an open structure. A plurality of mist outlets are also communicated and formed from the left side surface to the inner wall of the outer wall of the movable tube.

A plurality of exhalation ports are also formed from the outer periphery to the inner end face of the flexible mask. A connecting rope is also arranged on the flexible mask.

[0024] The beneficial effects of the present invention are:

[0025] 1. The present invention is provided with a fixed air pipe, a movable air pipe, a first straight groove, a sliding bar, a friction wheel and a rotating rod. When a child exhales, the airflow after exhalation can push the movable air pipe to move, and after moving, drive the sliding bar to move. In this way, the sliding bar can drive the friction wheel and the rotating rod to rotate, so that the upper shutter and the lower shutter can close the air delivery channel of the movable pipe. After closing, the exhaled airflow can be prevented from directly blowing towards the atomized gas entering.

[0026] 2. The present invention is provided with an installation groove, a clamping block, a movable ball and a fixed net at the fixed air pipe and the movable air pipe. When a child exhales, it can drive the movable ball to abut against the clamping block, so that the exhaled airflow can drive the movable air pipe to move. After moving, it can provide power support for the rotation of the baffle.

[0027] 3. The present invention is provided with a push block, a vertical groove, a vertical block, an extension rod, a third spring and a top plate. When the push block moves in a straight line towards the right, the lifting end of the push block can contact the extension rod. When the push block continues to move, the extension rod and the vertical block can be pushed upward through the slope structure of the lifting end. After moving, the first piston block at the push rod can quickly squeeze the air in the first inner cavity. After squeezing, the second piston block can quickly move in the second inner cavity, and then the installation sleeve can be quickly extended. Similarly, when the lifting end of the push block lifts the extension rod, it will move back to the left for reset. At this time, the pressing end on the left side of the push block can contact the extension rod by using the slope structure, so as to apply a downward pressure to the extension rod and the vertical block. Under the action of the pressure, the third spring is compressed, and then the rebound speed of the push rod is slowed down. At this time, the first piston block at the push rod slowly withdraws the air in the second inner cavity, so that the installation sleeve slowly returns to its original position. In this design, sufficient suction time can be provided for the atomized air around the installation sleeve, and then the situation of atomized air accumulation caused by too fast reset of the installation sleeve can be effectively avoided.

[0049] As shown in the attached Figure 1 to the attached Figure 9As shown in the figure: An auxiliary atomization device includes an atomization cup body 1, an atomization component, a connecting pipe 2, a movable pipe 3, a shielding component arranged in the movable pipe 3, and a transmission component for driving the shielding component to move. Among them, the atomization cup body 1 is provided with an exhaust port 106 that communicates from the upper left side of the inner wall to the outer end face. A filter screen 107 for dividing the atomized liquid medicine is arranged in the exhaust port 106. Then, a mist discharge pipe 108 corresponding to the exhaust port 106 is fixedly arranged on the outer surface of the atomization cup body 1. The outlet end of the mist discharge pipe 108 is provided with a thread groove 109 along the inner wall surface. The atomization component is arranged in the atomization cup body 1. The connecting pipe 2 is threadedly connected to the thread groove 109. The movable pipe 3 is slidably arranged on the left side of the connecting pipe 2. The shielding component is movably arranged on the left inner side of the connecting pipe 2. The transmission component is movably arranged inside the connecting pipe 2. During use, the transmission component can provide power for the shielding component to move.

[0050] The atomization component includes: an air inlet pipe 101, a bearing plate 102, a liquid outlet pipe 103, a liquid outlet head 104, and a baffle plate 105. The air inlet pipe 101 is arranged vertically at the lower end inside the atomization cup body 1, and its top end forms a reduced-diameter jet orifice, while the bottom end is connected to an external air source device. The bearing plate 102 is arranged at the upper end inside the atomization cup body 1. During use, the bearing plate 102 is used to form a liquid medicine pool. The liquid outlet pipe 103 is arranged horizontally at the lower end of the bearing plate 102, and the liquid inlet end of the liquid outlet pipe 103 is in communication with the lower inner end of the bearing plate 102, and the liquid outlet end extends towards the jet orifice at the top of the air inlet pipe 101. The liquid outlet head 104 is connected to the output port of the liquid outlet pipe 103. The baffle plate 105 is fixedly arranged above the air inlet pipe 101 through the lower surface of the bearing plate 102, and a conical protrusion is formed at the lower end of the baffle plate 105, and the protrusion is arranged corresponding to the jet orifice at the top of the air inlet pipe 101.

[0051] During use, external air source can introduce compressed air into the air inlet pipe 101, and then it is ejected from the jet orifice at the top of the air inlet pipe 101. Since the jet orifice has a reduced-diameter structure, when the compressed gas passes through the spacious inlet pipe and the narrow jet orifice, a negative pressure area will be formed. At this time, the liquid outlet pipe 103 and the liquid outlet head 104 are just located in the negative pressure area. Under the action of negative pressure, the liquid medicine in the bearing plate 102 can be sucked out through the liquid outlet pipe 103. After being sucked out, the liquid medicine will flow out through the liquid outlet head 104. Since the air flow at the jet orifice is moving upward at this time, the air flow can drive the liquid medicine to impact the baffle plate 105. After the impact, atomized gas containing liquid medicine can be formed, and then the gas enters into the exhaust port 106.

[0052] Furthermore, a top cover is threadedly provided at the top end of the atomizing cup body 1. During use, the user can open the top cover to inject new liquid medicine into the inside of the carrier plate 102. At the same time, air vents are provided on the upper and lower end faces of the top plate 55. This design enables the carrier plate 102 to communicate with the external atmosphere, so that the air pressure can be balanced after communication, thereby enabling the liquid outlet pipe 103 to suck liquid stably.

[0053] As Figure 3 , Figures 6 - 9 shown, the connecting pipe 2 further includes: a first inner cavity 21, a second inner cavity 26, and a second straight groove 5. The second straight groove 5 is opened in the middle of the inner wall of the connecting pipe 2 in a straight line direction. Then, the first inner cavity 21 is opened horizontally on the right side inside the connecting pipe 2, and the second inner cavity 26 is opened horizontally on the left side inside the connecting pipe 2. And a gas passage 29 is communicatively opened between the right sides of the first inner cavity 21 and the second inner cavity 26, and a gas is filled between the gas passage 29 and the first inner cavity 21 and the second inner cavity 26;

[0054] A push rod 22 is slidably arranged through and between the first inner cavity 21 and the second straight groove 5. One end of the push rod 22 facing the first inner cavity 21 is provided with a first piston block 23, and the first piston block 23 is also arranged to be mutually adapted to the first inner cavity 21. Then, a push plate 24 is fixedly arranged at one end of the push rod 22 facing the second straight groove 5, and a first spring 25 is sleeved on the outer surface of the push rod 22 between the push plate 24 and the inner end face of the second straight groove 5. Subsequently, a push block 241 is fixedly arranged horizontally at the middle of the front side and the middle of the rear side of the push plate 24. A lifting end with a slope structure is formed on the right side of the push block 241, and a pressing end with a slope structure is formed on the left side of the push block 241. The slope structures of the lifting end and the pressing end are arranged to be mutually parallel. During use, when the push plate 24 is pushed by an external force, the push plate 24 can drive the push rod 22 to move in the right direction. During the movement, the first piston block 23 can squeeze the air in the first inner cavity 21, and the squeezed air can enter the second inner cavity 26 through the gas passage 29, so that the components in the second inner cavity 26 can be pushed to move;

[0055] A connecting rod 27 is also slidably arranged through between the second inner cavity 26 and the outer side surface of the connecting pipe 2. One end of the connecting rod 27 facing the second inner cavity 26 is provided with a second piston block 28, and the second piston block 28 is also arranged to be mutually adapted to the second inner cavity 26. Then the other end of the connecting rod 27 is connected to the movable pipe 3. In use, when the gas in the first inner cavity 21 is squeezed into the second inner cavity 26 by the first piston block 23, the second piston block 28 can drive the connecting rod 27 to move in the left direction. After moving, it can drive the movable pipe 3 to move in the left direction together, so that the internal space formed by the movable pipe 3 and the connecting pipe 2 can be expanded. When the space increases, the accumulation of atomized air can be avoided.

[0056] Further, a circular ring-shaped mounting sleeve 49 is slidably arranged on the left inner wall of the connecting pipe 2. One end of the mounting sleeve 49 is connected to the movable pipe 3. In use, the mounting sleeve 49 can align the internal spaces of the connecting pipe 2 and the movable pipe 3, which helps the atomized gas to flow in the connecting pipe 2 and the movable pipe 3. In addition, the design of the mounting sleeve 49 can also adapt to the stretching process of the movable pipe 3. When the movable pipe 3 moves, it can provide sufficient accommodation space for the atomized gas.

[0057] Further, the left side of the movable pipe 3 is of a closed structure, while the right side is of an open structure. And a plurality of mist outlets 31 are communicated and opened from the left outer wall surface to the inner wall of the movable pipe 3. In use, the user can suck out the atomized gas in the movable pipe 3 and the connecting pipe 2 through the mist outlets 31. This design allows children to adapt to the inhalation process during atomization treatment.

[0058] Further, a circular pipe-shaped fixed air pipe 32 is fixedly arranged horizontally from the center of the left side of the movable pipe 3 to the inner wall surface. One end of the fixed air pipe 32 extends towards the left side of the movable pipe 3, and the other end extends into the movable pipe 3. In use, one end of the fixed air pipe 32 can be inserted into the mouth of a child. When the child inhales, a part of the atomized gas can be inhaled from the fixed air pipe 32. Similarly, when the child exhales, a part of the gas exhaled by the child can enter from the fixed air pipe 32.

[0059] In addition, it should be noted that the fixed air pipe 32 should be made of a hard pipe, and its diameter can refer to the finger diameter of an adult. This design ensures that when the fixed air pipe 32 is held in the mouth of a child, discomfort will not occur due to an overly large diameter. Secondly, when the fixed air pipe 32 is held in the mouth, there will be a gap between the lips and the fixed air pipe 32. This design allows the child to use this gap for rapid inhalation or exhalation operations, making the entire breathing process easy and smooth.

[0060] Further, a silica gel pad 33 in a round sleeve shape or a nipple shape is also provided on the left side of the fixed trachea 32. During use, the outer surface of the fixed trachea 32 can be wrapped by the silica gel pad 33. After wrapping, the silica gel pad 33 can meet the biting needs of children, thus meeting the biting needs of children and protecting the mouths of children.

[0061] As Figures 2 to 6 shown, the shielding assembly includes: a fixed seat 4, a slot 41, an upper shielding plate 42, a lower shielding plate 43, a rotating rod 44, a friction wheel 45, a first straight slot 46, and a sliding bar 47. The fixed seat 4 is in a rectangular frame structure and is fixedly arranged on the right inner wall of the movable tube 3. The slots 41 are respectively opened along the upper left side and the lower left side of the fixed seat 4. The upper shielding plate 42 and the lower shielding plate 43 are respectively arranged on the left side of the fixed seat 4 in the vertical direction. One end of the upper shielding plate 42 is also connected to the upper left slot 41, and one end of the lower shielding plate 43 is connected to the lower left slot 41. One end of the rotating rod 44 is rotatably connected to the inner wall surface of the slot 41, and the other end is connected to the corresponding upper shielding plate 42 / or the lower shielding plate 43. During use, the upper shielding plate 42 and the lower shielding plate 43 can be rotated at the slot 41 through the rotating rod 44. When the upper shielding plate 42 and the lower shielding plate 43 move inward or outward simultaneously, the two baffle plates 105 can shield or open the internal space of the movable tube 3. When in the shielding state, the exhaled gas can be prevented from directly blowing towards the atomized gas, thus avoiding the opposite flow of the two gases and preventing the continuously entering atomized gas from accumulating.

[0062] The friction wheel 45 is fixedly arranged on the rotating rod 44. The first straight slot 46 is horizontally opened on the inner wall surface of the fixed seat 4, and one end of the first straight slot 46 is also communicated with the slot 41. The sliding bar 47 is movably arranged inside the first straight slot 46, and the outer surface of the sliding bar 47 is meshed with the friction wheel 45. During use, the left and right movement of the sliding bar 47 can drive the friction wheel 45 and the rotating rod 44 to rotate, thus controlling the opening and closing process of the upper shielding plate 42 and the lower shielding plate 43.

[0063] Further, a chute 48 is horizontally opened on the inner wall surface of the first straight slot 46. A slider 481 is slidably arranged inside the chute 48 along the left side. One end of the slider 481 is connected to the sliding bar 47. A second spring 482 is arranged between the slider 481 and the right side inside the chute 48. During use, the second spring 482 is used to reset the displaced slider 481 and the sliding bar 47.

[0064] Further, the upper baffle 42 and the lower baffle 43 are specifically of a bucket structure. An opening penetrating through in a semi-circular structure is provided at the adjacent end of the upper baffle 42 and the lower baffle 43 along the middle position. When the upper baffle 42 and the lower baffle 43 approach and close to each other, the two semi-circular openings can form a circular accommodation channel 431. During use, this accommodation channel 431 can provide a reserved space for the installation of the fixed air pipe 32.

[0065] As Figures 4 to 7 shown, the transmission assembly includes: a movable air pipe 36, a mounting groove 34, an opening 35, a first support rod 361, a second support rod 362, a clamping block 37, a movable ball 38 and a fixing net 39. The mounting groove 34 is provided along the right inner wall of the fixed air pipe 32. One end of the movable air pipe 36 is slidably connected to the inner wall surface of the mounting groove 34, and the other end extends horizontally into the movable pipe 3 and the connecting pipe 2. The first support rod 361 and the second support rod 362 are respectively arranged at the middle end and the right side of the outer wall of the movable air pipe 36 in the vertical direction. One end of the first support rod 361 is also connected to the slide bar 47, and one end of the second support rod 362 extends into the second straight groove 5. This design enables the movable air pipe 36 to drive the first support rod 361 and the second support rod 362 to slide towards the right when the movable air pipe 36 is blown by an external force, and then it can be reset by the second spring 482 after sliding;

[0066] The movable air pipe 36 and the inner cavity of the fixed air pipe 32 are arranged in correspondence with each other. The clamping block 37 is in a V shape and is spaced on the left inner wall of the movable air pipe 36. The fixing net 39 is arranged on the right inner wall of the fixed air pipe 32 and is also opposite to the clamping block 37. The movable ball 38 is arranged to roll between the clamping block 37 and the fixing net 39. The width between the clamping blocks 37 is smaller than the diameter of the movable ball 38, and the width of the fixing net 39 is larger than the diameter of the movable ball 38. This design enables the air flow to drive the movable ball 38 to move to the fixing net 39 when a child inhales using the fixed air pipe 32, allowing the normal inhalation of the atomized gas. Similarly, when a child exhales, a part of the exhaled gas will enter the fixed air pipe 32, and then the movable ball 38 can block the channel of the clamping block 37 under the action of the air flow. When the air flow continuously enters, the movable air pipe 36 can be pushed to move towards the right with the cooperation of the movable ball 38, providing power for the movement of the movable air pipe 36;

[0067] The opening 35 is provided on the left inner wall of the installation groove 34, and one end of the opening 35 is also communicated with the outer wall surface of the fixed trachea 32. This design enables the exhaled gas to be discharged through the opening 35 after pushing the movable ball 38 to move a certain distance. After the discharge, the gas will not stay in the trachea, thus avoiding the situation that the movable trachea 36 will get stuck after moving a certain distance. Therefore, when a child exhales, he will not feel a strong sense of blockage, and thus it can be ensured that the child can maintain smoothness after exhaling.

[0068] Furthermore, the opening 35 is spaced from the upper shielding plate 42 and the lower shielding plate 43. This design enables the exhaled gas blown out from the opening 35 not to cause excessive interference to the movement process of the upper shielding plate 42 and the lower shielding plate 43.

[0069] As Figure 3 、 Figures 6 to 9 shown, at least one pair of limiting components are respectively provided on the front side and the rear side of the inner wall of the second straight groove 5. The limiting component includes: a vertical groove 51, a vertical block 52, an extension rod 53, a third spring 54 and a top plate 55. The vertical groove 51 is vertically provided on the inner wall surface of the second straight groove 5. The vertical block 52 is slidably arranged at the upper end inside the vertical groove 51. The extension rod 53 is fixedly arranged on the outer surface of the vertical block 52 along the front and rear directions, and the extension rod 53 also extends towards the movement path of the push block 241. When the vertical block 52 is in the initial state, its extension rod 53 can be aligned with the middle of the outer wall of the push block 241. This design enables the push block 241 to contact the extension rod 53 with its lifting end when the push block 241 moves linearly towards the right. When the push block 241 continues to move, the extension rod 53 and the vertical block 52 can be pushed to move upward through the slope structure of the lifting end. After the movement, the first piston block 23 at the push rod 22 can quickly squeeze the air in the first inner cavity 21. After the extrusion, the second piston block 28 can quickly move in the second inner cavity 26, and thus the installation sleeve 49 can be quickly extended;

[0070] The third spring 54 is arranged below the inside of the vertical groove 51, and the top plate 55 is connected to the upper end of the third spring 54. During use, the third spring 54 can push the top plate 55 to move upward, and the lower surface of the vertical block 52 also contacts the top plate 55. This design enables the push block 241 to move away from the vertical block 52 after the lifting end of the push block 241 lifts the extension rod 53. At this time, the vertical block 52 drives the extension rod 53 back to the initial position under the action of gravity. When the child stops exhaling, the first spring 25 and the second spring 482 force the second support rod 362 and the push rod 22 to reset and slide, that is, the movable trachea 36 and the push rod 22 move in the left direction. When the push block 241 continuously moves in the left direction, its left pressing end can contact the extension rod 53 by using the slope structure, so that a downward pressure can be applied to the extension rod 53 and the vertical block 52. Under the action of the pressure, the third spring 54 is compressed, thereby slowing down the rebound speed of the push rod 22. At this time, the first piston block 23 at the push rod 22 slowly draws back the air in the second inner cavity 26, so that the mounting sleeve 49 slowly returns to its position. Under this design, sufficient suction time can be provided for the atomized air around the mounting sleeve 49, and thus the situation of atomized air accumulation caused by the too-fast reset of the mounting sleeve 49 can be effectively avoided.

[0071] Furthermore, when the push plate 24 moves to the extreme position on the right side of the second straight groove 5, the resilience of its first spring 25 should be greater than the resistance generated by the third spring 54 when it is compressed. This design enables the first spring 25 to still push the push plate 24 to perform subsequent reset work after the resistance of the third spring 54 consumes part of the resilience of the first spring 25.

[0072] Furthermore, the extension rod 53 is arranged at intervals with both the push plate 24 and the second support rod 362. This design enables the second support rod 362 not to interfere with the movement process of the extension rod 53 when it pushes the push plate 24 to move.

[0073] As Figure 1 and Figure 6 shown, a flexible mask 6 made of silica gel is also arranged on the left outer wall of the movable tube 3. During respiratory treatment, the user can wear the flexible mask 6 on the child's mouth for breathing. Secondly, due to the material characteristics of the flexible mask 6, its structure can naturally deform with the expansion of the movable tube 3, so that the flexible mask 6 can adapt to the expansion process of the movable tube 3.

[0074] Furthermore, a plurality of exhalation ports 61 are opened from the outer periphery to the inner end face of the flexible mask 6. During use, the child can perform auxiliary exhaust through the exhalation ports 61.

[0075] Further, a connecting rope 62 is also provided on the flexible face mask 6. During use, the user can stably mount the flexible face mask 6 at the mouth of a child through the connecting rope 62.

[0076] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
