Description

Technical Field

[0001] This utility model relates to an alcohol cotton ball storage container, and in particular discloses an alcohol cotton ball quantitative dispensing storage container. Background Technology

[0002] Currently, common alcohol swab storage devices on the market can be roughly divided into two categories:

[0003] One type is the simple wide-mouth bottle: it consists of a cylindrical plastic or glass wide-mouth bottle, a threaded top cap, and an internal plastic sealing gasket. The sealing gasket is pressed between the top cap and the bottle mouth to form a simple seal. To use, unscrew the threaded top cap and use tweezers or your fingers to pick up the cotton ball. It has no additional moving parts or electrical components.

[0004] The second type is disposable plastic bags: these consist of an alcohol-soaked cotton ball inside a plastic bag, which is then heat-sealed. To use, the bag is torn open and the cotton ball is removed with tweezers or by hand. Its structural feature is that the bag is formed by heat-sealing three sides of a plastic composite film and leaving an easy-tear opening on one side; it has no rigid structure, no moving parts, and no electrical components.

[0005] The above-mentioned existing technologies have the following disadvantages:

[0006] Poor sealing: Each time the wide-mouth bottle is opened to take out cotton, the alcohol inside evaporates rapidly, causing the upper cotton balls to dry out and become ineffective. Once the plastic bag is torn open, the remaining cotton balls are completely exposed and cannot be completely sealed again.

[0007] 2. High risk of cross-contamination: When taking out the product, tweezers or fingers need to be inserted into the bottle, which may easily touch unused cotton balls; the tweezers themselves may also become a source of contamination after being reused.

[0008] 3. Difficult to measure the amount: When tilting or picking up cotton balls from a wide-mouthed bottle, multiple cotton balls are often brought out at once or the cotton balls fall off; it is also difficult to control the amount taken out after the aluminum foil bag is torn open.

[0009] 4. Inconvenient to operate: Opening / tightening the bottle cap requires two hands, which is difficult to use in emergency or one-handed situations; the tear of the plastic bag is prone to irregularity, causing the contents to spill out.

[0010] 5. Alcohol evaporation leads to a decrease in concentration: The sealing gasket of the bottle ages over time, further reducing its sealing effect; once the plastic bag is torn open, the evaporation rate is faster, affecting the disinfection effect. Utility Model Content

[0011] The purpose of this invention is to overcome the defects in the existing technology and provide an alcohol cotton ball quantitative dispensing storage tank with good sealing performance, quantitative dispensing, prevention of secondary pollution, convenient use, simple structure, and low manufacturing cost.

[0013] The centerline of the first cotton storage channel is a straight line, an arc, or a spiral; the height of the second cotton storage channel is the total height that can accommodate the total number of alcohol cotton balls falling at once.

[0014] The toggle handle is provided with a cotton dropping mark corresponding to the second cotton dropping hole; the tank body is provided with a cotton storage channel position mark corresponding to the position of the second cotton storage channel.

[0015] The angle between the line connecting the center point of the top surface and the center point of the bottom surface of the first cotton storage channel and the plane containing the bottom surface of the first cotton storage device is 75 degrees to 90 degrees.

[0016] The rotating linkage includes a first connecting rod, which passes through the center of the sealing cover, the first cotton storage device, the first rotating disk, the second cotton storage device, and the second rotating disk from top to bottom along the central axis of the tank. The first connecting rod is fixedly connected to the first rotating disk and the second rotating disk respectively and can drive the first rotating disk and the second rotating disk to rotate synchronously. The actuating handle is located above the sealing cover and fixed to the top of the first connecting rod.

[0017] The toggle handle is connected to the first connecting rod via a thread or a pluggable structure.

[0018] The rotating linkage includes a second connecting rod, the upper end of which is rotatably connected to the center of the first cotton storage device. The center of the first rotating disk is fixed on the second connecting rod. The second connecting rod passes vertically through the middle of the second cotton storage device and is rotatably connected to the middle of the second cotton storage device.

[0043] The present invention will be further described below with reference to specific embodiments. Example 1:

[0044] according to Figure 6 Figure 7 combined Figures 3-5The rotating linkage includes a second connecting rod 18, the upper end of which is rotatably connected to the center of the first cotton storage device 3. The center of the first rotating disk 4 is fixed on the second connecting rod 18. The second connecting rod 18 passes vertically through the middle of the second cotton storage device 5 and is rotatably connected to the middle of the second cotton storage device 5. The center of the second rotating disk 6 is fixed to the lower end of the second connecting rod 18. The actuating handle 12 is a ring handle fixed around the first rotating disk 4 or the second rotating disk 6. Figure 6 The actuating handle 12 is fixed around the first rotating disk 4. A handle rotation window 19 corresponding to the annular handle is provided on the side wall of the tank body 1; the annular handle protrudes from or is located within the handle rotation window 19. The remaining structure is as described above. Example 2:

[0045] according to Figure 8 , combined Figure 1 , Figure 2 In this embodiment, the center line of the first cotton storage channel 7 of the first cotton storage device 3 is a straight line, and the angle between the center line of the first cotton storage channel 7 and the plane where the bottom surface of the first cotton storage device 3 is located is 80 degrees. That is, the first cotton storage channel 7 is a straight pipe that is inclined relative to the horizontal plane. Compared with the vertical straight pipe, it can reduce the pressure between the upper and lower alcohol cotton balls in the first cotton storage channel 7. The rest of the structure is as described above. Example 3:

[0046] according to Figure 9 , combined Figure 1 , Figure 2 In this embodiment, the centerline 21 of the first cotton storage channel is an arc or a spiral. The angle α between the line 20 connecting the center points of the top and bottom surfaces of the first cotton storage channel 7 and the plane containing the bottom surface of the first cotton storage device is 85 degrees. That is, the first cotton storage channel 7 is an arc-shaped or spiral pipe as a whole. The entire pipe of the first cotton storage channel 7 is inclined to one side, which can further reduce the pressure between the upper and lower alcohol cotton balls in the first cotton storage channel 7 and prevent excessive compression. The remaining structure is as described above. Example 4:

[0047] according to Figure 11 , Figure 12 , combined Figure 1 and Figure 2 A cotton dropping positioning device is provided between the second cotton storage device 5 and the first rotating disk 4, or between the second cotton storage device 5 and the second rotating disk 6. In this embodiment, Figure 11 , Figure 12In this configuration, the cotton drop positioning device is located between the second cotton storage device 5 and the first rotating disk 4. The cotton drop positioning device includes a mounting groove 22, a spring 23, a top bead 24, and a limiting groove 25 for accommodating the upper part of the top bead 24. The mounting groove 22 is fixed inside the second cotton storage device 5, and its opening is located on the top or bottom surface of the second cotton storage device 5. One end of the spring 23 is fixed to the bottom of the mounting groove 22, and the other end of the spring 23 presses against the top bead 24, restricting the top bead 24 within the opening of the mounting groove 22. The limiting groove 25 is located on the first rotating disk 4 or the second rotating disk 6 and corresponds to the position of the top bead 24. The number of mounting grooves 22, springs 23, and top beads 24 is the same as the number of the first cotton storage channels 7 and corresponds to their positions. The number of limiting grooves 25 is one or the same as the number of the first cotton storage channels 7. When there is one limiting groove 25, the limiting groove 25 is located on one side of the baffle 8 or the second cotton drop hole 11; when the number of limiting grooves 25 is the same as the number of the first cotton storage channels 7, each limiting groove 25 corresponds to any one top bead 24.

[0048] During the rotation of the first rotating disk 4 and the second rotating disk 6, when the top bead 24 falls into the limiting groove 25, the second cotton drop hole 11 is connected to one of the second cotton storage channels 10. When the rotation is applied again, the top bead 24 is squeezed into the mounting groove 22 by the first rotating disk 4 or the second rotating disk 6. When the rotation is applied again until the top bead 24 is aligned with the limiting groove 25, the top bead 24 is pushed out into the limiting groove 25 under the action of the spring 23, forming a noticeable jamming sensation, indicating that the second cotton storage channel 10 is connected to the second cotton drop hole 11, forming an alcohol cotton ball falling pattern.

[0049] The working principle of this utility model is as follows: According to Figures 3-5 The first cotton storage device 3 and the second cotton storage device 5 are fixed relative to each other, and the first cotton storage channel 7 and the second cotton storage channel 10 are always vertically aligned. Assume... Figure 3 In the initial state, the five first cotton drop holes 9 on the first rotating disk 4 are respectively connected vertically to the five corresponding first cotton storage channels 7 and the five second cotton storage channels 10; the baffle 8 separates the corresponding one first cotton storage channel 7 and one second cotton storage channel 10 vertically. The one second cotton storage channel 10 separated by the baffle 8 is connected downward to the second cotton drop hole 11 and the cotton ball falling cavity 13. The lower ends of the other five second cotton storage channels 10 are closed by the second rotating disk 6, blocking the passage between them and the cotton ball falling cavity 13.

[0050] In use, open the sealing cover 2 and add alcohol cotton balls into the first cotton storage channel 7 of the first cotton storage device 3. When the lever 12 is turned to drive the first rotating disk 4 and the second rotating disk 6 to rotate, the alcohol cotton balls in the first cotton storage channel 7 cannot fall when the first cotton drop hole 9 and the second cotton drop hole 11 are misaligned with the first cotton storage channel 7 and the second cotton storage channel 10, respectively. When the lever 12 is turned so that the first cotton drop hole 9 and the second cotton drop hole 11 are vertically aligned with the first cotton storage channel 7 and the second cotton storage channel 10, respectively, the alcohol cotton balls in the second cotton storage channel 10 below the baffle 8 fall into the cotton ball falling cavity 13 through the second cotton drop hole 11. The remaining alcohol cotton balls in the second cotton storage channel 10 are blocked by the second rotating disk 6 and remain in the second cotton storage channel 10.

[0051] Similarly, when the lever handle 12 is turned again until the baffle 8 and the second cotton drop hole 11 are aligned with another first cotton storage channel 7, the previously empty second cotton storage channel 10 connects with the first cotton storage channel 7, and the alcohol cotton ball in the first cotton storage channel 7 enters the second cotton storage channel 10 again. At this time, the alcohol cotton ball in the second cotton storage channel 10 below the baffle 8 falls into the cotton ball falling cavity 13. This achieves the goal of only one alcohol cotton ball falling at a time.
