Description

Technical Field

[0001] The utility model relates to a liquid storage device, in particular to a liquid storage device with a bubble blocking structure. Background Art

[0002] Medical nebulizers are mainly used to administer drugs through the user's respiratory system. The user pours a certain dose of liquid medicine into the liquid reservoir inside the nebulizer, and the atomization unit in the liquid reservoir atomizes the liquid medicine into tiny aerosol molecules with a specific particle size. The aerosol molecules with a specific particle size are then delivered from the user's mouth and nose to enter the user's respiratory system through breathing and achieve the purpose of treatment through the circulatory system.

[0003] In the existing atomizer, a detection unit is arranged inside the liquid reservoir to detect the amount of liquid medicine in the liquid reservoir. The detection unit can detect and determine whether the liquid medicine in the liquid reservoir is about to run out, and output a corresponding detection signal to the control unit in the atomizer to stop the operation of the atomizer unit in advance, so as to avoid the atomizer unit from continuing to vibrate and causing damage when the liquid medicine runs out.

[0062] The following is an explanation of the implementation of the "liquid storage device" disclosed in the present utility model through specific embodiments. Those skilled in the art can understand the advantages and effects of the present utility model from the contents disclosed in this specification. The present utility model can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of the present utility model. In addition, the drawings of the present utility model are only simple schematic illustrations and are not depicted according to actual dimensions. It is stated in advance. The following implementation methods will further explain the relevant technical contents of the present utility model in detail, but the disclosed contents are not intended to limit the scope of protection of the present utility model.

[0063] It should be understood that, although the terms "first", "second", "third", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are mainly used to distinguish one element from another element. In addition, the term "or" used herein may include any one or more combinations of the associated listed items depending on the actual situation.

[0064] First embodiment

[0065] See also Figures 1 to 3 As shown, the first embodiment of the utility model provides a liquid storage device M suitable for a nebulizer (not shown), which includes a liquid storage tank 1, an atomization module 2, a detection module 3, a cover body 4 and a bubble blocking structure 5. The interior of the liquid storage tank 1 is a receiving cavity for storing liquid medicine. The top of the liquid storage tank 1 has an opening 101, and the bottom of the liquid storage tank 1 has a through hole 102. The opening 101 and the through hole 102 are connected through the receiving cavity. The atomization module 2 is arranged in the through hole 102. The detection module 3 is arranged in the liquid storage tank 1, exposed in the receiving cavity and adjacent to the through hole 102.

[0066] When the medicine liquid is stored in the liquid storage tank 1, the detection module 3 will be immersed in the medicine liquid, so that the detection module 3 can detect the amount of the medicine liquid to determine whether the medicine liquid in the liquid storage tank is about to run out. After the medicine liquid passes through the through hole 102 and is atomized by the atomization module 2 to form an aerosol, it is sprayed into the user's mouth and nose through the nozzle of the atomizer (not shown). The cover body 4 covers the opening 101. Specifically, the cover body 4 has a pivot 41, and the cover body 4 is connected to the pivot shaft 11 of the liquid storage tank 1 through the pivot 41 to perform actions such as opening or closing.

[0067] like Figure 2 and Figure 3 As shown, the bubble blocking structure 5 includes a partition wall 51, which is connected to the lower surface of the bubble blocking structure 5 and extends toward the through hole 102. Further, the two sides of the bubble blocking structure 5 are respectively provided with a first fixing rib 521 and a second fixing rib 522, which are used to strengthen the structural strength of the partition wall 51.

[0068] When the cover 4 is closed, the bubble blocking structure 5 is located in the liquid storage tank 1. Figure 3 As shown, the lower edge 510 of the partition wall 51 is lower than the detection module 3 and higher than the through hole 102; more specifically, there is a gap between the lower edge 510 and the through hole 102, and the height of the gap can be selected to be 0.2mm to 10mm. The projection area of ​​the partition wall 51 vertically projected to the bottom of the liquid storage tank 1 at least partially overlaps with the through hole 102; more specifically, the projection area of ​​the partition wall 51 vertically projected to the bottom of the liquid storage tank 1 is located in the center of the through hole 102.

[0069] Thus, the partition wall 51 can utilize its surface characteristics to adhere to or attract bubbles generated when the liquid medicine is atomized, and utilize structural design to block bubbles. When bubbles are generated during the atomization process of the liquid medicine, the bubbles are isolated by the partition wall 51 and will not cover or remain on the detection area of ​​the detection module 3, thereby preventing the bubbles from covering or remaining on the detection area and affecting the detection result of the detection module 3.

[0070] It should be noted that the above example is only one feasible embodiment and is not intended to limit the present invention. The subsequent other embodiments are mainly used to illustrate the changes of the bubble blocking structure 5, and the structures of the liquid storage tank 1, the atomization module 2, the detection module 3 and the cover 4 of the liquid storage device M are similar to those of the first embodiment.

[0071] Second embodiment

[0072] See also Figure 4 and Figure 5As shown, the second embodiment of the utility model provides a liquid storage device M, which includes a liquid storage tank 1, an atomization module 2, a detection module 3, a cover body 4 and a bubble blocking structure 5. The top of the liquid storage tank 1 has an opening 101, and the bottom of the liquid storage tank 1 has a through hole 102. The atomization module 2 is arranged in the through hole 102. The detection module 3 is arranged in the liquid storage tank 1 and adjacent to the through hole 102. The cover body 4 is pivotally connected to the liquid storage tank 1 and covers the opening 101.

[0073] The bubble blocking structure 5 includes a partition wall 51, and the partition wall 51 is connected to the lower surface of the bubble blocking structure 5. The projection area of ​​the partition wall 51 vertically projected to the bottom of the liquid storage tank 1 is located between the center of the through hole 102 and the detection module 3. Therefore, compared with the first embodiment ( Figure 3 ), the partition wall 51 is closer to the detection module 3. In an optional manner, the lower edge of the partition wall 51 has a protruding portion 511, and the protruding portion 511 extends into the through hole 102 and abuts against the inner edge of the through hole 102.

[0074] Third embodiment

[0075] See also Figure 6 and Figure 7 As shown, the third embodiment of the utility model provides a liquid storage device M, which includes a liquid storage tank 1, an atomization module 2, a detection module 3, a cover body 4 and a bubble blocking structure 5. The top of the liquid storage tank 1 has an opening 101, and the bottom of the liquid storage tank 1 has a through hole 102. The atomization module 2 is arranged in the through hole 102. The detection module 3 is arranged in the liquid storage tank 1 and adjacent to the through hole 102. The cover body 4 is pivotally connected to the liquid storage tank 1 and covers the opening 101.

[0076] The bubble blocking structure 5 includes a partition wall 51, which is connected to the lower surface of the bubble blocking structure 5. A first fixed rib 521 is provided on one side of the partition wall 51, and two second fixed ribs 522 are provided on the other side. The two second fixed ribs 522 are respectively vertically projected to the bottom of the liquid storage tank to form two projection areas, and the through hole 102 is located between the two projection areas. The first fixed rib 521 and the two second fixed ribs 522 are used to strengthen the structural strength of the partition wall 51. The lower edge 510 of the partition wall 51 is lower than the detection module 3 and higher than the through hole 102. There is a gap between the lower edge 510 and the through hole 102, and the height of the gap can be selected from 0.2 mm to 10 mm. The projection area of ​​the partition wall 51 vertically projected to the bottom of the liquid storage tank 1 is located in the center of the through hole 102.

[0077] Fourth embodiment

[0078] See also Figures 8 to 10The fourth embodiment of the utility model provides a liquid storage device M, which includes a liquid storage tank 1, an atomization module 2, a detection module 3, a cover body 4 and a bubble blocking structure 5. The top of the liquid storage tank 1 has an opening 101, and the bottom of the liquid storage tank 1 has a through hole 102. The atomization module 2 is disposed in the through hole 102. The detection module 3 is disposed in the liquid storage tank 1 and adjacent to the through hole 102. The cover body 4 has a through hole 40, and the cover body 4 is pivotally connected to the liquid storage tank 1 and covers the opening 101.

[0079] The bubble blocking structure 5 further includes a straight pipe 53, and the straight pipe 53 has a first port 531 and a second port 532. The straight pipe 53 is connected to the lower surface of the cover body 4 through the first port 531, the first port 531 is connected to the through hole 40, and the second port 532 extends into the through hole 102. It should be noted that the diameter of the second port 532 is smaller than the diameter of the through hole 102, so when the second port 532 extends into the through hole 102, there is still a gap between the straight pipe 53 and the through hole 102 without blocking the through hole 102, so that the liquid medicine stored in the liquid storage tank 1 can flow into the through hole 102 and be atomized by the atomization module 2.

[0080] In an optional manner, the straight-through pipe 53 is funnel-shaped, and the diameter of the straight-through pipe 53 gradually decreases from the first port 531 to the second port 532. In this way, bubbles generated by the liquid medicine during atomization will be collected by the straight-through pipe 53, and these bubbles are adsorbed on the surface of the straight-through pipe 53, and move up along the surface of the straight-through pipe 53 to be collected inside the straight-through pipe 53. In other words, after being collected by the straight-through pipe 53, these bubbles will be isolated and will not cover or remain on the detection area of ​​the detection module 3, so as to avoid affecting the detection result of the detection module 3 due to the bubbles covering or remaining on the detection area.

[0081] Fifth embodiment

[0082] See also Figures 11 to 13 The fifth embodiment of the utility model provides a liquid storage device M, which includes a liquid storage tank 1, an atomization module 2, a detection module 3, a cover body 4 and a bubble blocking structure 5. The top of the liquid storage tank 1 has an opening 101, and the bottom of the liquid storage tank 1 has a through hole 102. The atomization module 2 is disposed in the through hole 102. The detection module 3 is disposed in the liquid storage tank 1 and adjacent to the through hole 102. The cover body 4 has a circular through hole 40, and the cover body 4 is pivotally connected to the liquid storage tank 1 and covers the opening 101.

[0083] The bubble blocking structure 5 includes a partition wall 51 and a straight pipe 53. The straight pipe 53 is connected to a side of the partition wall 51 facing away from the detection module 3. The partition wall 51 is connected to the lower surface of the bubble blocking structure 5. The projection area of ​​the partition wall 51 vertically projected to the bottom of the liquid storage tank 1 is located in the center of the through hole 102. The straight pipe 53 has a first port 531 and a second port 532, the first port 531 is connected to the cover body 4 and communicates with the through hole 40, and the second port 532 extends to the top of the through hole 102.

[0084] The straight pipe 53 is cylindrical, and the diameters of the first port 531 and the second port 532 are substantially the same. Since the straight pipe 53 is connected to one side of the partition wall 51, the second port 532 is not completely opposite to the through hole 102, that is, the projection area of ​​the straight pipe 53 vertically projected to the bottom of the liquid storage tank 1 only partially overlaps with the through hole 102. Fig.13 As shown, there is a gap between the bottom of the straight pipe member 53 and the through hole 102 .

[0085] Thereby, the bubbles generated by the liquid medicine during the atomization process can not only be collected inside the straight-through pipe 53, but also be further blocked by the partition wall 51 to avoid the bubbles covering or remaining on the detection area and affecting the detection result of the detection module 3.

[0086] Sixth embodiment

[0087] See also Figures 14 to 16 The sixth embodiment of the utility model provides a liquid storage device M, which includes a liquid storage tank 1, an atomization module 2, a detection module 3, a cover body 4 and a bubble blocking structure 5. The top of the liquid storage tank 1 has an opening 101, and the bottom of the liquid storage tank 1 has a through hole 102. The atomization module 2 is disposed in the through hole 102. The detection module 3 is disposed in the liquid storage tank 1 and adjacent to the through hole 102. The cover body 4 has a flat through hole 40, and the cover body 4 is pivotally connected to the liquid storage tank 1 and covers the opening 101.

[0088] The bubble blocking structure 5 includes a partition wall 51 and an annular wall 54. The partition wall 51 is connected to the lower surface of the bubble blocking structure 5. The annular wall 54 is connected to a side of the partition wall 51 facing away from the detection module 3, and the annular wall 54 and the partition wall 51 together form a straight pipe. The straight pipe is connected to the through hole 40. Due to the shape of the annular wall 54, the straight pipe formed is flat and cylindrical. A notch 512 is formed at the lower edge of the partition wall 51.

[0089] The projection area of ​​the partition wall 51 vertically projected to the bottom of the liquid storage tank 1 is located in the center of the through hole 102. In addition, there is a gap between the bottom notch 512 of the partition wall 51 and the through hole 102, so that the liquid medicine stored in the liquid storage tank 1 can flow in. Since the annular wall 54 is connected to one side of the partition wall 51, the projection area of ​​the straight-through pipe formed vertically projected to the bottom of the liquid storage tank 1 only partially overlaps with the through hole 102. In this way, the bubbles generated by the liquid medicine during the atomization process can not only be collected inside the straight-through pipe, but also be further blocked by the partition wall 51 to avoid affecting the detection result of the detection module 3 due to the bubbles covering or remaining on the detection area.

[0090] Seventh embodiment

[0091] See also Fig.17 and Fig.18 The seventh embodiment of the utility model provides a liquid storage device M, which includes a liquid storage tank 1, an atomization module 2, a detection module 3, a cover body 4 and a bubble blocking structure 5. The top of the liquid storage tank 1 has an opening 101, and the bottom of the liquid storage tank 1 has a through hole 102. The atomization module 2 is disposed in the through hole 102. The detection module 3 is disposed in the liquid storage tank 1 and adjacent to the through hole 102. The cover body 4 is pivotally connected to the liquid storage tank 1 and covers the opening 101.

[0092] The bubble blocking structure 5 includes a partition wall 51, an annular wall 54, and a retaining structure 55. The annular wall 54 is connected to a side of the partition wall 51 facing away from the detection module 3, and the annular wall 54 and the partition wall 51 together form a straight pipe. Due to the shape of the annular wall 54, the straight pipe formed is flat and cylindrical. A notch 512 is formed at the lower edge of the partition wall 51, and there is a gap between the notch 512 and the through hole 102, so that the liquid medicine stored in the liquid storage tank 1 can flow in. The retaining structure 55 is connected to the partition wall 51 and the annular wall 54.

[0093] The projection area of ​​the partition wall 51 vertically projected onto the bottom of the liquid storage tank 1 is located at the center of the through hole 102, so the projection area of ​​the straight-through pipe formed by the partition wall 51 and the annular wall 54 vertically projected onto the bottom of the liquid storage tank 1 only partially overlaps the through hole 102. Through the structural design of the partition wall 51 and the annular wall 54, the bubbles generated by the liquid medicine during the atomization process can not only be collected inside the straight-through pipe, but also be further blocked by the partition wall 51, so as to avoid the bubbles covering or remaining on the detection area and affecting the detection result of the detection module 3.

[0094] Further, the holding structure 55 includes a plurality of convex abutments 551, a plurality of connecting members 552 and an annular member 553. The annular member 553 surrounds the outer sides of the partition wall 51 and the annular wall 54, and both ends of the partition wall 51 are connected to the annular member 553. Some of the connecting members 552 are connected between the partition wall 51 and the annular member 553, and other connecting members 552 are connected between the annular wall 54 and the annular member 553. A plurality of convex abutments 551 are connected to the annular member 553 and are evenly distributed around the straight-through pipe. By designing the holding structure 55, the structural strength of the bubble blocking structure 5 can be strengthened.

[0095] In the seventh embodiment, the bubble blocking structure 5 is a detachable independent component.

The top of the liquid storage tank 1 has an opening 101, and the bottom of the liquid storage tank 1 has a through hole 102. The atomization module 2 is disposed in the through hole 102. The detection module 3 is disposed in the liquid storage tank 1 and adjacent to the through hole 102. The cover body 4 is pivotally connected to the liquid storage tank 1 and covers the opening 101.

[0098] The bubble blocking structure 5 includes a partition wall 51, an annular wall 54 and two first fixing members 56. The annular wall 54 is connected to a side of the partition wall 51 facing away from the detection module 3, and the annular wall 54 and the partition wall 51 together form a flat cylindrical straight-through pipe. The two first fixing members 56 are connected to both ends of the partition wall 51. The liquid storage tank 1 has two second fixing members 12. Fig. 20 and Fig.21 As shown, for example, the two first fixing members 56 may be convex columns, and the two second fixing members 12 may be concave holes. Therefore, the bubble blocking structure 5 can be fixed in the liquid storage tank 1 by the two first fixing members 56 being respectively engaged with the two second fixing members 12 (i.e., the two convex columns are respectively engaged with the two concave holes). A notch 512 is formed at the lower edge of the partition wall 51, and there is a gap between the notch 512 and the through hole 102, so that the liquid medicine stored in the liquid storage tank 1 can flow into the through hole 102.

[0099] In other words, the bubble blocking structure 5 is a detachable independent component. That is, the bubble blocking structure 5 can be assembled in the liquid reservoir 1, and can also be disassembled from the liquid reservoir 1 for easy cleaning. When the bubble blocking structure 5 is assembled in the liquid reservoir 1, the bubbles generated by the liquid during the atomization process can not only be collected inside the straight-through pipe, but also be further blocked by the partition wall 51, so as to avoid the bubbles covering or remaining on the detection area and affecting the detection result of the detection module 3.

The perforated mesh 57 is inserted into a plurality of fixing posts (not shown) of the plurality of connecting arms 533 and fixed to the straight pipe 53. When the cover body 4 is closed, the perforated mesh 57 can be appropriately located above the through hole 102. The perforated mesh 57 has a plurality of mesh holes 570.
