Description

Technical Field

[0001] This utility model belongs to the field of valve technology, specifically relating to a manual / automatic integrated exhaust valve and a fermentation tank. Background Technology

[0002] As people's living standards improve, the demand for beverages is increasing, including various fermented drinks containing alcohol, acetic acid, and fruit vinegar. Fermentation is a process under suitable conditions, using fruits or grains as raw materials, and utilizing microorganisms to transform these raw materials into products needed by humans through specific metabolic pathways. During fermentation, some metabolic gases are produced, and when these gases accumulate to a certain level, degassing is often necessary.

[0003] To address this, utility model patent CN218267293U discloses an exhaust valve for brewing containers. This valve has a through-hole inside its body, with a valve core extending through the hole. The top of the valve core protrudes from the valve body and is rotatably connected to a lever. An inverted conical plug is located at the bottom of the valve core, and an elastic rubber ring is fixedly installed at the bottom opening of the valve body. A spring is fitted around the valve core, pressing the plug against the elastic rubber ring. By manually pressing the lever, the valve core is pulled, causing the inverted conical plug to lose its sealing effect on the elastic rubber ring, thus creating an exhaust passage. While this exhaust valve achieves its function, it requires periodic manual operation, which is cumbersome. Furthermore, its complex structure reduces assembly efficiency, and the need for a fixing nut increases the number of components. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a manual / automatic integrated exhaust valve and fermentation tank that can automatically exhaust gas according to the gas pressure and has a simplified structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A manual / automatic integrated exhaust valve is designed, including a valve seat, a valve cavity with a top opening in the valve seat, and an air inlet hole communicating with the valve cavity on the bottom wall of the valve seat. The valve body is installed in the valve cavity, and a through hole is formed in the valve body. A valve stem is provided in the through hole, and a valve plug is provided at the lower end of the valve stem. The valve plug can seal the air inlet hole. The lower end of the valve stem is connected to the elastic body, and the upper end of the elastic body is connected to the valve body. The upper end of the valve stem has a hinge portion, and the valve stem is hinged to a hand handle through the hinge portion. The hand handle has a downwardly protruding support portion, which is eccentrically positioned with the hinge portion. The support portion can support the valve body on the outer periphery of the through hole.

[0006] Preferably, the valve plug is a horn cover.

[0007] Preferably, the lower part of the valve stem has a support, the upper part of the valve body has a support platform, and the upper end of the elastic body is abutted on the support platform and the lower end is abutted on the support.

[0008] Preferably, the elastic body is a spring, which is fitted onto the valve stem.

[0009] Preferably, the outer wall of the valve seat has a raised ridge.

[0010] Preferably, the valve seat has a first flange on top, and a convex ridge is supported on the first flange.

[0011] Preferably, the valve body is provided with a second flange, which can form a clamping groove with the first flange.

[0012] Preferably, the valve body is inserted into the valve seat.

[0013] Preferably, the valve seat is provided with a slider, and a sliding groove is opened on the outer wall of the valve body. The sliding groove has a cartridge section and a pin section connected to the cartridge section. The cartridge section is arranged along the vertical direction of the valve body, and the pin section is arranged along the circumference of the valve body. The lower end of the cartridge section is connected to the bottom wall of the valve body.

[0014] This utility model also provides a fermentation tank, including a tank body and a cover mounted on the tank body, characterized in that: the cover body is equipped with the aforementioned manual / automatic exhaust valve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Because a valve body is installed in the valve cavity of the valve seat, and an air inlet hole communicating with the valve cavity is opened on the bottom wall of the valve seat, and a through hole is opened in the valve body, a valve stem is installed in the through hole, and a valve plug that can block the air inlet hole is provided at the lower end of the valve stem. Furthermore, an elastic body is installed between the valve stem and the valve body, so that when the gas pressure is high enough, it pushes the valve plug to overcome the elastic force of the elastic body and move upward, losing the blocking effect on the air inlet hole. The air inlet hole and the through hole form an exhaust passage, realizing automatic exhaust. A hand lever is hinged to the top of the valve stem. By pressing the hand lever, the valve stem can be pulled upward, so that the valve plug loses its blocking effect on the air inlet hole, realizing manual exhaust. Moreover, the matching relationship between the valve seat, valve body and valve stem simplifies the overall structure of the exhaust valve, enhances its stability, and also helps to improve its production efficiency.

[0017] 2. Because the valve plug adopts a horn-shaped structure, the horn-shaped structure is placed on the air inlet, which reduces the contact area between the valve plug and the valve seat and increases the contact area with the gas to be vented. This makes it easier for the gas to be vented to push the valve plug and facilitates self-venting.

[0018] 3. Because the lower part of the valve stem has a support and the upper part of the valve body has a support platform, the upper end of the elastic body is attached to the support platform and the lower end is attached to the support, which facilitates the installation of the elastic body.

[0019] 4. Because the elastic body uses a spring, it is fitted onto the valve stem, which can constrain the movement direction of the valve stem and ensure that the valve plug can reliably open and close the vent.

[0020] 5. Because the outer wall of the valve seat has ridges, it is possible to prevent the valve seat from rotating circumferentially by gripping the outer wall of the valve seat, which facilitates the fitting between the valve seat and the valve body by fixing the valve seat.

[0021] 6. Since the valve seat has a first flange on top, and the convex ridge is supported on the first flange, it can increase the contact area with the valve seat, and at the same time realize the supporting effect of the convex ridge on the first flange, thereby enhancing its installation strength.

[0022] 7. Because the valve body is provided with a second flange, the second flange can form a clamping groove with the first flange, which allows the mounting body for installing the exhaust valve, such as the bottle cap, to be clamped in the clamping groove. This not only enhances the installation strength but also simplifies the installation structure and facilitates improved installation efficiency.

[0023] 8. Because the valve body adopts a cartridge installation structure in the valve seat, the technology is mature and easy to implement, and the installation process is simplified, which is more conducive to improving its installation efficiency and cost performance.

[0024] 9. This utility model has an ingenious design. Its structure not only enables manual and automatic venting, reducing the labor intensity of fermentation workers, but also simplifies the structure of the venting valve and enhances its operational reliability. It is worthy of being promoted and used in the industry. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0032] When this utility model is in working condition, the end away from the ground is defined as the top or upper end, and the other end closer to the ground is defined as the lower end or bottom end.

[0033] like Figure 1 As shown, this utility model has a valve cavity with an open top in the valve seat 1. An air inlet 11 communicating with the valve cavity is provided on the bottom wall of the valve seat 1. A valve body 6 is installed in the valve cavity. A through hole 13 is provided in the valve body 6, and a valve stem 10 is provided inside the through hole 13. The outer periphery of the valve stem 10 has a ventilation gap 19, meaning the cross-section of the through hole 13 is larger than the cross-section of the valve stem 10. A horn-shaped valve plug is provided at the lower end of the valve stem 10, forming a horn cover 12 that covers the air inlet 11. A support 14 is provided at the lower part of the valve stem 10, and a support platform 15 is provided at the upper part of the valve body 6. A spring 16 is fitted on the valve stem 10, with the upper end of the spring 16 abutting against the support platform 15 and the lower end abutting against the support 14. The upper end of the valve stem 10 has a hinge portion 18, and the valve stem 10 is hinged to the hand handle 8 through the hinge portion 18. The hand handle 8 has a downwardly protruding support portion 17, and the support portion 17 and the hinge portion 18 are eccentrically arranged. The support portion 17 can be supported on the valve body 6 on the outer periphery of the through hole 13.

[0034] To facilitate the installation and operation between the valve seat 1 and the valve body 6, this utility model also provides a protruding ridge 2 on the outer wall of the valve seat 1, and a first flange 3 on the top of the valve seat 1, with the protruding ridge 2 supported on the first flange 3. A second flange 7 is provided on the valve body 6, which can form a clamping groove 9 with the first flange 3, so that the tank lid of the fermentation tank can be clamped in the clamping groove 9, facilitating the installation of the exhaust valve. A protruding slider 4 is also provided in the valve cavity of the valve seat 1, and a sliding groove 5 is opened on the outer wall of the valve body 6. The slider 4 is inserted into the sliding groove 5. The sliding groove 5 has an insertion section 51 and a pin section 52 connected to the insertion section 51. The insertion section 51 is arranged along the vertical direction of the valve body 6, and the pin section 52 is arranged along the circumference of the valve body 6, so that the sliding groove 5 is generally "L" shaped. The lower end of the insertion section 51 is connected to the bottom wall of the valve body 6, thus realizing the insertion connection of the valve body 6 in the valve seat 1.

[0035] This utility model also applies the above-mentioned exhaust valve to a fermentation tank. Specifically, a cover is installed on the tank body, and an installation hole is opened on the cover so that the cover around the installation hole is clamped in the clamping groove 9 of the exhaust valve.

[0036] The working process of this utility model is as follows:

[0037] When the fermentation process in the fermenter causes the gas to accumulate to a certain level and the pressure inside the tank reaches a certain point, the horn cover 12 is pushed upwards through the air inlet 11, overcoming the elastic force of the spring 16. This causes the horn cover 12 to lose its sealing effect on the air inlet 11, allowing the gas inside the tank to enter the through hole 13 of the valve body 6 through the air inlet 11 and exit from the top of the through hole 13. When the gas is discharged to a certain extent, and it is no longer sufficient for the spring 16 to elastically deform and cause the horn cover 12 to detach from the bottom wall of the valve seat 1, the sealing effect on the air inlet 11 is automatically restored, completing one automatic venting cycle. Alternatively, the hand lever 8 can be manually pressed to rotate, thereby pulling the valve stem 10 upwards. The horn cover 12 then detaches from the bottom wall of the valve seat 1, similarly losing its sealing effect on the air inlet 11 and venting. After venting is complete, the hand lever 8 is reset to restore the sealing effect of the horn cover 12 on the air inlet 11, completing manual venting.

[0038] Besides using the aforementioned spring 16 as the elastic body, other elastic components such as rubber can also be used, as long as they can undergo elastic deformation under external force and automatically return to their original shape after the external force is removed. No specific requirements are placed on their structure. Similarly, in addition to the aforementioned insert structure, a sliding groove can be opened on the valve seat 1 and other insert structures such as a slider can be set on the valve body 6 between the valve seat 1 and the valve body 6.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model are not permitted.
