[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0022] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0023] Example 1:

[0024] like Figures 1-4 As shown, this utility model provides a valve for dispensing a two-component mixture, comprising: a valve body 100, the valve body 100 including a first valve body 1 and a second valve body 2, the upper part of the first valve body 1 being movably and sealingly disposed on the upper end of an outer tank 200, and the lower part being disposed on an inner tank 300, the inner tank 300 being located inside the outer tank 200, the upper part of the first valve body 1 having a first guide hole 101 communicating with the outer tank 200, the second valve body 2 being disposed inside the first valve body 1, and the second valve body 2 having a second guide hole 201 communicating with the inner tank 300.

[0025] In use, the second valve body 2 is installed into the first valve body 1. After filling the inner tank 300 with material A, the inner tank 300 is installed at the lower part of the first valve body 1, corresponding to the second valve body 2. The second valve body 2 is pressed to make the second guide hole 201 communicate with the inner tank 300, and then the inner tank 300 is inflated through the second guide hole 201. Then, material B is filled into the outer tank 200, and the inner tank 300 is inserted into the outer tank 200. The upper part of the first valve body 1 is movably sealed and installed at the upper end of the outer tank 200. The first valve body 1 is pressed to make the first guide hole 101 communicate with the outer tank 200, and then the outer tank 200 is inflated through the first guide hole 101.

[0026] Finally, the first valve body 1 and the second valve body 2 are pressed, and then material A and material B are sprayed out from their respective first guide hole 101 and second guide hole 201 due to gas pressure to achieve the mixing of the two components. This achieves the effect of mixing on the spot and avoids the failure or explosion of the materials inside if the two substances are mixed in advance.

[0027] Example 2:

[0028] Exemplary First Valve Body: Further, some embodiments of the present invention provide a specific structure of the first valve body 1 described above. This first valve body 1 includes a first valve stem 11, a sealing cup 12, a sealing plug 13, and a gasket 14. The upper end of the sealing cup 12 has an outwardly bent annular groove 121, which can be connected to the upper end of the outer can 200. A gasket 14 is located within the annular groove 121 to enhance the sealing effect and prevent leakage of material B from the outer can 200. The sealing plug 13 is installed in the central hole of the sealing cup 12, and the first valve stem 11 passes through the sealing plug 13. The sealing plug 13 ensures a seal between the first valve stem 11 and the sealing cup 12, preventing leakage of material B from the outer tank 200. During use, the first valve stem 11 can be driven downwards, pressing the sealing plug 13 and moving downwards. This creates a gap 130 between the lower part of the first valve stem 11 and the bottom of the sealing plug 13. Material B from the outer tank 200 then enters the first guide hole 101 through the gap 130 and is sprayed outwards to mix with material A, achieving a mixing effect on demand and avoiding premature mixing that could cause the material to fail or explode.

[0029] After the upper part of the first valve body 1 is reset, the sealing plug 13 will block the gap 130 again to prevent material B from leaking out, thereby achieving a movable sealing connection between the second valve body 2 and the upper end of the outer tank 200.

[0030] Example 3:

[0031] Exemplary First Valve Stem Body: Further, some embodiments of the present invention provide a specific structure of the first valve stem body 11 described above. Here, the first valve stem body 11 of this structure includes an upper valve stem 111 and a lower valve seat 112. The upper valve stem 111 passes through the sealing plug 13, and the lower valve seat 112 is installed at the bottom of the upper valve stem 111 and located inside the outer tank 200. The lower valve seat 112 is connected to the inner tank 300. The upper valve stem 111 has a first flow guide hole 101 inside, and a side flow guide hole 113 corresponding to the first flow guide hole 101 is opened on the side wall.

[0032] Therefore, material B inside the outer tank 200 enters the side guide hole 113 through the gap 130, and then enters the first guide hole 101 and is sprayed outward. Here, the first guide hole 101 has an inner partition 102, and the second valve body 2 is partially inserted into the inner partition 102 and partially located in the lower valve seat 112. The inner partition 102 separates the second valve body 2 from the inner wall of the first guide hole 101, so that material B enters the first guide hole 101 and is sprayed outward along the inner partition 102, avoiding material B from contacting the outer wall of the second valve body 2 as soon as it enters the first guide hole 101. This facilitates the mixing of material A and material B after they are sprayed out of the valve body 100, improving the mixing effect.

[0033] Example 4:

[0034] Exemplary Second Valve Body: Further, some embodiments of the present invention provide a specific structure of the above-mentioned second valve body 2, wherein the second valve body 2 of this structure includes a second valve stem 21 and an inner spring 22, wherein a second flow guide hole 201 is provided in the second valve stem 21, and the second valve stem 21 passes through the inner cavity 102 of the first flow guide hole 101. A spring stop 211 is provided on the outer wall of the second valve stem 21, and the inner spring 22 is sleeved on the second valve stem 21 and abuts against the bottom of the spring stop 211 and the inner cavity 102. During use, the second valve stem 21 is pressed to connect the second guide hole 201 inside the second valve stem 21 with the inner tank 300. In this way, material A in the inner tank 300 can be sprayed out through the second guide hole 201, thereby mixing with material B to achieve the effect of mixing on the spot, avoiding the failure or explosion of the materials inside if the two substances are mixed in advance. After use, the support spring stop 211 moves upward under the action of the inner spring 22, thereby resetting the second valve stem 21 for convenient subsequent use.

[0035] Example 5:

[0036] Furthermore, in some embodiments of the present invention, a sealing gasket 23 is installed on the lower outer wall of the second valve stem 21. Here, the sealing gasket 23 abuts against the bottom of the first valve body 1. Correspondingly, a sealing groove 10 is provided at the bottom of the first valve body 1. The sealing groove 10 corresponds to the sealing gasket 23. There is a guide hole between the sealing groove 10 and the inner partition cylinder 102. The second valve stem 21 passes through the guide hole. Therefore, when the second valve stem 21 is pressed, the lower end of the second valve stem 21 moves downward, and then the sealing gasket 23 moves out from the sealing groove 10. In this way, the second guide hole 201 communicates with the inner tank 300, which facilitates the outward spraying of material A and the mixing of two components with material B. This achieves the effect of mixing on demand and avoids the failure or explosion of the materials inside if the two substances are mixed in advance.

[0037] Example 6:

[0038] Furthermore, in some embodiments of the present invention, a sealing ring 103 and a gasket 104 are also installed at the bottom of the inner partition 102. Here, the sealing ring 103 and the gasket 104 are sleeved on the second valve stem 21 and located at the bottom of the inner spring 22, serving to support the inner spring 22. The gasket 104 is located above the sealing ring 103. Therefore, when the second valve stem 21 moves, the sealing effect in the inner partition 102 is achieved through the sealing ring 103, preventing the second valve stem 21 from opening and the material A from being discharged from the second valve stem 21 when pressed, and also preventing material B from entering the inner tank.

[0039] Example 7:

[0040] Furthermore, in some embodiments of the present invention, a side opening 212 is provided on the outer wall of the second valve stem body 21, and the side opening 212 is connected to the second guide hole 201. The side opening 212 is located above the sealing gasket 23. Therefore, when the second valve stem body 21 is pressed, the lower end of the second valve stem body 21 moves downward, and then the sealing gasket 23 moves out of the sealing groove 10. In this way, the side opening 212 enables the second guide hole 201 to be connected to the inner tank 300, so that material A can enter the second guide hole 201 through the side opening 212 and be sprayed outward, thereby mixing with material B to achieve the effect of mixing on demand, avoiding the failure or explosion of the material inside if the two substances are mixed in advance.
