Description

Technical Field

[0001] This application relates to the field of neutralization cups, and more particularly to a hydrogen peroxide neutralization cup. Background Technology

[0002] A hydrogen peroxide neutralization cup is a specialized device used to detect hydrogen peroxide concentration or for hydrogen peroxide disinfection. It mainly consists of a cylindrical glass cup with a small hole at the bottom for connecting a test tube. Its core principle is based on the reaction of hydrogen peroxide with potassium iodide solution to produce oxygen; the concentration of hydrogen peroxide is determined by observing the number of bubbles. Hydrogen peroxide is a strong oxidizing agent widely used in medical, hygiene, and environmental protection fields.

[0003] The utility model patent with announcement number CN222341427U proposes a hydrogen peroxide neutralization cup, including: a cup body and a lid; the inner side of the lid is provided with a slot, a cleaning rack is inserted into the slot, the front and back of the cleaning rack are provided with a lens basket, one end of the lens basket is connected to the cleaning rack and can rotate, and the tail end of the cleaning rack is provided with a neutralization ring.

[0004] One of the hydrogen peroxide neutralization cups described above produces bubbles during use, creating pressure inside the cup. This pressure is released through a vent on the lid to prevent the cup from bursting. However, during storage, dust easily falls onto the lid and blocks the vent, making it difficult to clear and reducing ease of use. Utility Model Content

[0005] To address the aforementioned issues, this application provides a hydrogen peroxide neutralization cup.

[0006] The hydrogen peroxide neutralization cup provided in this application adopts the following technical solution:

[0007] A hydrogen peroxide neutralization cup includes a cup body and a cup lid. The upper surface of the cup lid has two vent holes. The cup lid is provided with a unclogging component for unblocking the vent holes. The unclogging component includes multiple fixing rods fixedly connected to the top of the cup lid. A pressure plate is provided at the top of the cup lid above the vent holes. Two unclogging rods are fixedly connected to the lower surface of the pressure plate. The unclogging rods are respectively located directly above the vent holes. A spring is sleeved on each fixing rod. One end of the spring is attached to the pressure plate, and the other end of the spring is attached to the cup lid. The fixing rods and the pressure plate are provided with a locking component for preventing the springs from rebounding.

[0008] By adopting the above technical solution, when in use, pressing the pressure plate causes it to move downward under the guidance of the fixed rod, allowing the unblocking rod to pass through the vent hole. At the same time, the spring is compressed. After releasing the pressure plate, the spring rebounds, pushing the pressure plate upward and causing the unblocking rod to move out of the vent hole, thus unblocking the vent hole. This minimizes the problem of dust falling onto the cover and clogging the vent hole during storage, making it difficult to unclog and reducing the convenience of use.

[0009] Preferably, the locking assembly includes a limiting plate fixedly connected to the top of the fixing rod, and the pressure plate has slots at both ends, with a fixing shaft fixedly connected in each slot, and an L-shaped limiting block sleeved on each fixing shaft.

[0010] By adopting the above technical solution, when the spring rebounds, the pressure plate is pushed out of the fixing rod by the limiting plate. At the same time, when storing, the pressure plate is pressed and then the L-shaped limiting block is swung so that the L-shaped limiting block is located below the limiting plate. When the spring rebounds, the L-shaped limiting block abuts against the limiting plate, restricting the spring rebound and keeping the unblocking rod in the vent hole, sealing the vent hole and preventing dust from entering the vent hole.

[0011] Preferably, an elastic rubber block adapted to the vent hole is fixedly connected to the end of the unblocking rod away from the pressure plate.

[0012] By adopting the above technical solution, when the unblocking rod is moved into the vent hole, the elastic rubber block is squeezed into the vent hole and attached to the side wall of the vent hole, which can improve the unblocking effect of the vent hole.

[0013] Preferably, the lower surface of the cup lid has a groove, the vent is located in the groove, a connecting cylinder is fixedly connected to the lower surface of the cup lid in the groove, a silicone pad is sleeved on the connecting cylinder, a pressure plate for attaching the silicone pad to the lower surface of the cup lid is sleeved at the bottom of the connecting cylinder, a connecting sleeve is fixedly connected to the lower surface of the pressure plate, the connecting sleeve is sleeved on the connecting cylinder and has an air inlet at its bottom.

[0014] By adopting the above technical solution, firstly, the silicone pad is placed on the connecting cylinder, and then the connecting sleeve is placed on the connecting cylinder, so that the pressure plate adheres the silicone pad to the lower surface of the cup lid, so that the cup body is inverted under normal pressure, and the liquid cannot leak out through the vent hole. When pressure is generated during the neutralization reaction of hydrogen peroxide, the gas pressure enters the connecting sleeve through the air inlet, and then seeps out in the gap between the connecting sleeve and the connecting cylinder, contacting the silicone pad, squeezing open the central hole of the silicone pad, so that the gas pressure is discharged into the vent hole through the gap between the central hole of the silicone pad and the connecting cylinder.

[0015] Preferably, two conical blocks are fixedly connected to the lower surface of the cup lid, and the conical blocks are located on both sides of the connecting cylinder and are in contact with the connecting cylinder.

[0016] By adopting the above technical solution, when the silicone pad ages or sticks to the connecting cylinder after long-term use, causing the gap between the silicone pad and the connecting cylinder to become blocked, the air pressure inside the cup will continue to rise, which will push the silicone pad into the groove, causing the cone-shaped block to squeeze and puncture the central hole of the silicone pad to release the gas and prevent the gas from being difficult to escape.

[0017] Preferably, a buffer rubber pad is fixedly connected to the upper surface of the pressure plate.

[0018] By adopting the above technical solution, the cushioning rubber pad can provide cushioning when the person presses the pressure plate, improving the pressing comfort. At the same time, when the pressure plate is pressed against the cup lid, the cushioning rubber pad can adhere to the cup lid, reducing the wear of the pressure plate on the cup lid.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. This application utilizes the coordinated structure of a fixed rod, a pressure plate, and a spring. During use, pressing the pressure plate causes it to move downwards under the guidance of the fixed rod, allowing the unblocking rod to pass through the vent hole. Simultaneously, the spring is compressed. After releasing the pressure plate, the spring rebounds, pushing the pressure plate upwards and causing the unblocking rod to move out of the vent hole, thus clearing the vent hole. This design minimizes the problem of dust easily falling onto the cover and clogging the vent hole during storage, making it difficult to clear and reducing ease of use.

[0021] 2. With prolonged use, the silicone pad may age or stick to the connecting cylinder, causing blockage in the gap between the silicone pad and the connecting cylinder. This leads to a continuous increase in air pressure inside the cup, which pushes the silicone pad into the groove. The conical block then squeezes and punctures the center hole of the silicone pad to release the gas and prevent it from being difficult to escape. Attached Figure Description

Detailed Implementation

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0028] This application discloses a hydrogen peroxide neutralization cup.

[0029] Reference Figure 1 , Figure 2 and Figure 3 A hydrogen peroxide neutralization cup includes a cup body 1 and a cup lid 2. Two vent holes 3 are opened on the upper surface of the cup lid 2. The cup lid 2 is provided with a unclogging component for unblocking the vent holes 3. The unclogging component includes a fixing rod 4, a pressure plate 5, an unblocking rod 6 and a spring 7.

[0030] Multiple fixing rods 4 are provided, all fixedly connected to the top of the cup lid 2. Two vent holes 3 are located between the multiple fixing rods 4. The pressure plate 5 is set at the top of the cup lid 2 and above the vent holes 3. Two unblocking rods 6 are provided, both fixedly connected to the lower surface of the pressure plate 5. The unblocking rods 6 are respectively located directly above the vent holes 3 and can be inserted into the vent holes 3. Multiple springs 7 are provided, each sleeved on the fixing rod 4. One end of the spring 7 is attached to the pressure plate 5, and the other end of the spring 7 is attached to the cup lid 2. The fixing rods 4 and the pressure plate 5 are provided with locking components to prevent the springs 7 from rebounding.

[0031] Reference Figure 1 and Figure 2 The locking assembly includes a limiting plate 8 fixedly connected to the top of the fixing rod 4. The pressure plate 5 has slots 19 at both ends, and a fixing shaft 20 is fixedly connected to each slot 19. An L-shaped limiting block 21 is fitted on each fixing shaft 20. When the spring 7 rebounds, the limiting plate 8 prevents the pressure plate 5 from being pushed out of the fixing rod 4. At the same time, when storing, the pressure plate 5 is pressed and the L-shaped limiting block 21 is swung so that the L-shaped limiting block 21 is located below the limiting plate 8. When the spring 7 rebounds, the L-shaped limiting block 21 abuts against the limiting plate 8, restricting the spring 7 from rebounding, so that the unblocking rod 6 is located in the vent hole 3, sealing the vent hole 3 and preventing dust from entering the vent hole 3.

[0032] Reference Figure 2 and Figure 3The end of the unblocking rod 6 away from the pressure plate 5 is fixedly connected to an elastic rubber block 10 that is compatible with the vent hole 3. When the unblocking rod 6 is moved into the vent hole 3, the elastic rubber block 10 is squeezed into the vent hole 3 and the elastic rubber block 10 is attached to the side wall of the vent hole 3, which can improve the unblocking effect of the vent hole 3.

[0033] Reference Figure 2 and Figure 4 The lower surface of the cup lid 2 has a groove 11, and the vent 3 is located in the groove 11. A connecting cylinder 12 is fixedly connected to the lower surface of the cup lid 2 in the groove 11. A silicone pad 13 is fitted on the connecting cylinder 12. A pressure plate 14 for attaching the silicone pad 13 to the lower surface of the cup lid 2 is fitted at the bottom end of the connecting cylinder 12. A connecting sleeve 15 is fixedly connected to the lower surface of the pressure plate 14 (the bottom end of the connecting sleeve 15 is equipped with a placement part for placing contact lenses and a neutralizing ring with a platinum-plated surface. The placement part and the neutralizing ring are prior art and are not shown in the figure. For details, please refer to the announcement number CN222341427U, which will not be elaborated here). The connecting sleeve 15 is fitted onto the connecting cylinder 2. An air inlet 16 is provided on the cylinder 12 and at its bottom. First, the silicone pad 13 is placed on the connecting cylinder 12, and then the connecting sleeve 15 is placed on the connecting cylinder 12. The pressure plate 14 makes the silicone pad 13 adhere to the lower surface of the cup lid 2, so that the cup body 1 is inverted under normal pressure. The liquid cannot leak out through the vent 3. When pressure is generated during the neutralization reaction of hydrogen peroxide, the gas pressure enters the connecting sleeve 15 through the air inlet 16, and then seeps out through the gap between the connecting sleeve 15 and the connecting cylinder 12 to contact the silicone pad 13, squeezing open the central hole of the silicone pad 13, so that the gas pressure is discharged into the vent 3 through the gap between the central hole of the silicone pad 13 and the connecting cylinder 12.

[0034] Reference Figure 2 and Figure 4 Two conical blocks 17 are fixedly connected to the lower surface of the cup lid 2. The conical blocks 17 are located on both sides of the connecting cylinder 12 and fit against the connecting cylinder 12. After long-term use, the silicone pad 13 will age or stick to the connecting cylinder 12. When the gap between the silicone pad 13 and the connecting cylinder 12 is blocked, the air pressure inside the cup body 1 will continue to rise, which will push the silicone pad 13 into the groove 11. The conical blocks 17 will squeeze and puncture the central hole of the silicone pad 13 to release the gas and prevent the gas from being difficult to escape.

[0035] Reference Figure 1 A buffer rubber pad 18 is fixedly connected to the upper surface of the pressure plate 5. The buffer rubber pad 18 can buffer the pressure when the person presses the pressure plate 5, improving the pressing comfort. At the same time, when the pressure plate 5 is pressed against the cup lid 2, the buffer rubber pad 18 is attached to the cup lid 2, which can reduce the wear of the pressure plate 5 on the cup lid 2.

[0036] The implementation principle of a hydrogen peroxide neutralization cup according to an embodiment of this application is as follows: In use, firstly, by pressing the pressure plate 5, it moves downward under the guidance of the fixing rod 4, allowing the unblocking rod 6 to pass through the vent hole 3, while simultaneously compressing the spring 7. After releasing the pressure plate 5, the spring 7 rebounds, pushing the pressure plate 5 upward, causing the unblocking rod 6 to move out of the vent hole 3, thus unblocking the vent hole 3. Then, the silicone pad 13 is fitted onto the connecting cylinder 12, and then the connecting sleeve 15 is fitted onto the connecting cylinder 12 and connected to it, so that the pressure plate 14 presses the silicone pad 13 against the lower surface of the cup lid 2. Then, the cup lid 2 is... After the cup body 1 is connected, it is inverted under normal pressure, preventing the liquid from leaking out through the vent hole 3. During the neutralization reaction of hydrogen peroxide, when pressure is generated, the gas pressure enters the connecting sleeve 15 through the air inlet 16, and then seeps out through the gap between the connecting sleeve 15 and the connecting cylinder 12, contacting the silicone pad 13. This forces open the central hole of the silicone pad 13, allowing the gas pressure to be discharged through the gap between the central hole of the silicone pad 13 and the connecting cylinder 12 into the vent hole 3. This minimizes the risk of dust falling onto the lid during storage and blocking the vent hole, making it difficult to clear and reducing the ease of use.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
