DETAILED DESCRIPTION

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0036] The principle of the present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0037] As attached Figure 1 The disinfectant making machine has an electrolysis chamber 100 for electrolyzing a saline solution at its bottom, a cup mouth 2 is provided at the top of the electrolysis chamber, and the cup mouth 2 is sealed by a cover 1.

[0038] Hydrogen is produced in real time during the electrolysis process, so uninterrupted exhaust and pressure relief are required; however, the disinfectant making machine is a handheld device. During operation, the disinfectant making machine may shake, tilt, or even collide and fall due to the operator's carelessness, causing the internal solution to flow out.

[0039] The cover body 1 includes a side edge and a top wall, the side edge is provided with an internal thread, and the cup mouth is provided with an external thread. The cover body 1 is connected to the cup mouth 2 by a non-sealing thread, which can prevent the solution in the electrolytic chamber 100 from flowing out to a certain extent; the non-sealing thread is an ordinary thread that cannot achieve a sealing effect. Due to the non-sealing thread connection, there is a thread gap 4 between the side edge and the cup mouth 2;

[0040] In order to further improve the sealing performance, a sealing ring 3 is provided between the cover 1 and the cup mouth 2;

[0041] In order to meet the exhaust requirements, an exhaust groove 5 is opened on the surface of the sealing ring 3, one end of the exhaust groove 5 is connected to the inner cavity of the cup mouth 2, and the other end is connected to the thread gap 4;

[0042] As attached Figure 2 As shown, hydrogen enters the exhaust groove 5 from the inner side of the cup mouth 2, and then is discharged along the exhaust groove 5 at the outer side of the cup mouth 2 through the thread gap 4. The exhaust groove 5 forms a capillary channel connecting the electrolytic chamber 100 with the outside, and the surface tension of the liquid is used to limit the outflow of the solution. When the air pressure in the electrolytic chamber 100 increases, the exhaust groove 5 can smoothly discharge the hydrogen to achieve the purpose of pressure relief.

[0043] The cross-sectional size and quantity of the exhaust groove 5 need to be adjusted to the optimal parameters according to the characteristics of the actual product, and the sealing performance should be improved as much as possible under the premise of ensuring safe exhaust and pressure relief;

[0044] First, the size of the exhaust groove 6 needs to be calculated based on the maximum water pressure of the solution volume allowed to be stored in the electrolytic chamber. The more solution there is, the greater the water pressure will be when pouring. At this time, the cross-sectional area of ​​the corresponding exhaust groove 5 needs to be set smaller, and the number of exhaust grooves 5 should be increased accordingly.

[0045] In addition, the cross-sectional size and number of the exhaust grooves 5 also need to be set according to the maximum pressure that the solution in the electrolytic chamber 100 can generate. The specific size should be the maximum size that the solution will not leak out quickly through the exhaust grooves.

[0046] In view of the use environment of the disinfectant manufacturing machine, the optimal size of the exhaust groove 5 is a groove depth of 0.5 mm and a width of 0.6 mm.

[0047] During the rotation process, the cover body 1 squeezes the sealing ring 3 to keep the sealing ring 3 in a certain compression amount to ensure the sealing state. Therefore, it is necessary to avoid the sealing ring 3 being compressed and deformed to block the exhaust groove 5, so that the hydrogen cannot be discharged.

[0048] The exhaust groove 5 includes a first section 51 opened on the inner side of the sealing ring 3, a third section 53 opened on the outer side of the sealing ring 3, and a second section 52 opened on the upper surface of the sealing ring 3 and connecting the first section 51 and the third section 53. The exhaust groove 5 runs from the inner side of the sealing ring 3 to the upper side and then to the outer side.

[0049] Usually, the cross-sectional width of the sealing ring is larger than the wall thickness of the cup mouth, and the upper part of the sealing ring is in contact with the top wall of the cover body. Therefore, when the cover body is tightened, the pressure at the bottom of the sealing ring 3 is greater than that at the top. Therefore, the exhaust groove 5 is arranged around the upper part of the sealing ring 3 to avoid blocking the exhaust groove 5 when the sealing ring 3 is deformed under pressure.

[0050] In order to further ensure the necessary exhaust channel when the sealing ring 3 is squeezed, the width of the exhaust groove 5 gradually shrinks from the groove mouth to the groove bottom. The cross-section of the exhaust groove 5 can be set to semicircular, U-shaped, or V-shaped. The optimal technical solution is V-shaped. Compared with semicircular and U-shaped grooves, V-shaped grooves are easier to ensure that a small exhaust channel is left, and are less likely to be completely blocked due to large compression.

[0051] As attached Figure 5 As shown, when the cross section of the exhaust groove 5 is V-shaped, the angle of the V-shape is an acute angle. After testing, when the hardness of the rubber of the sealing ring is 30-35HA Shore A, the optimal angle is 34.7°.

[0052] Compared with the first section 51, the second section 52 and the third section 53 of the exhaust groove 5, the first section 51 and the second section 52 extend vertically, the second section 52 extends laterally, and the second section 52 directly bears the pressure of the cover body 1, so the second section 52 is more likely to be blocked due to the deformation of the sealing ring 3;

[0053] In order to further prevent the second section 52 from being blocked, the upper portion of the sealing ring 3 is provided with a truncated cone-shaped first inclined surface 31 to reduce the pressure of the second section 52;

[0054] In order to fix the sealing ring 3, a slot for fixing the sealing ring 3 is provided at the lower part of the top wall of the cover body 1, and the top of the slot is provided as a second inclined surface 11 matching the first inclined surface 31;

[0055] The first inclined surface 31 and the second inclined surface 11 cooperate with each other to increase the force-bearing area of ​​the upper part of the sealing ring 3 and reduce the pressure accordingly;

[0056] A circular or annular clamping edge 12 extends downward from the top wall of the cover body 1, and the clamping groove is composed of the second inclined surface 11, the side edge of the cover body 1 and the clamping edge 12;

[0057] The clamping edge 12 can support the sealing ring 3 on the inner side of the sealing ring 3 to prevent the sealing ring 3 from deforming inwards;

[0058] The first section 51 extends downward and is exposed at the lower portion of the clamping edge 12 , and is communicated with the inner cavity of the cup mouth 2 .

[0059] In order to further improve the sealing performance of the sealing ring, a convex ring 32 is provided on the upper part of the sealing ring 3, and the convex ring 32 is coaxially arranged with the sealing ring 3;

[0060] The convex ring 32 can enhance the sealing effect, so that the exhaust position is limited to the grooved position, and the remaining part is sealed to prevent water leakage, so that the exhaust is controllable.

[0061] Example 1

[0062] This embodiment provides a first structure of the sealing ring 3 and the exhaust groove 5 .

[0063] like Figure 3-4 As shown, a first inclined surface 31 is provided on the upper part of the sealing ring 3, and two circles of convex rings 32 are provided on the first inclined surface 31;

[0064] The cross section of the exhaust groove 5 is V-shaped, the V-shaped angle is an acute angle, the groove depth is 0.5mm, and the width is 0.6mm;

[0065] The first section 51 extends vertically along the sealing ring 3 , the second section 52 extends radially along the sealing ring 3 , and the third section 53 extends vertically along the sealing ring 3 . The cross-sectional shapes and sizes of the first section 51 , the second section 52 and the third section 53 are the same.

[0066] In this embodiment, four exhaust grooves 5 are provided, and the number of the exhaust grooves 5 is set according to the electrolysis rate of the product, that is, the hydrogen generation rate, so as to balance the hydrogen generation and discharge amounts without causing an increase in the internal gas pressure.

[0067] Example 2

[0068] This embodiment provides a second structure of the sealing ring 3 and the exhaust groove 5 .

[0069] like Figure 6 As shown, a first inclined surface 31 is provided on the upper part of the sealing ring 3, and two circles of convex rings 32 are provided on the first inclined surface 31;

[0070] The cross section of the exhaust groove 5 is also V-shaped, the V-shaped angle is an acute angle, the groove depth is 0.5mm, and the width is 0.6mm.

[0071] The first section 51 extends vertically along the sealing ring 3, the third section 53 extends vertically along the sealing ring 3, and the second section 52 extends in an angle with the radial direction of the sealing ring, extending obliquely between the first section 51 and the third section 53 in a beveled shape;

[0072] The advantage is that the length of the exhaust groove 5 after the matching sealing ring 3 is compressed can be effectively extended to increase the sealing effect;

[0073] The upper portion of the sealing ring 3 is still provided with a first inclined surface 31 to reduce the pressure of the second section 52 .

[0074] In this embodiment, four exhaust grooves 5 are provided, and the specific number is set according to the method in Embodiment 1.

[0075] Example 3

[0076] This embodiment provides a third structure of the sealing ring 3 and the exhaust groove 5 .

[0077] like Figure 7 As shown, an annular groove 54 is added on the upper surface of the sealing ring 3 and coaxially with the sealing ring 3, and the second section 52 extending from the inside to the outside is cut into a second section A 521 and a second section B 522;

[0078] One end of the second section A 521 is connected to the first section 51, and the other end is connected to the annular groove 54;

[0079] One end of the second section B 522 is connected to the third section 53, and the other end is connected to the annular groove 54;

[0080] Furthermore, the annular groove 54 is staggered with the intersection of the second section A 521 and the second section B 522 .

[0081] The annular groove 54 is a V-shaped groove similar to the exhaust groove, the V-shaped angle is an acute angle, the groove depth is 0.5 mm, and the width is preferably 0.6 mm;

[0082] After the hydrogen enters the exhaust groove 5 from the first section 51, it passes through the second section A521-the part of the annular groove 54-the second section B522-the third section 53, and finally is discharged through the thread gap 4;

[0083] Since the exhaust route of this embodiment is extended, the sealing effect is improved without affecting the exhaust;

[0084] In addition, the annular groove 54 connects the plurality of exhaust grooves 5 into a whole. If one of the exhaust passages is blocked, the hydrogen can bypass the annular groove 54 to other passages for discharge.

[0085] In this embodiment, four second segments A521 and four second segments B522 are provided, and the specific number is set according to the method in Embodiment 1.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
