[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Please refer to Figures 1 to 3 The present invention provides a valve device, which includes: a hose 1, which is deformably arranged; the hose 1 has a first port and a second port that are connected to each other; a tube clamping structure 2, which is separately arranged from the hose 1, so that the hose 1 can be clamped or released by the tube clamping structure 2; when the tube clamping structure 2 clamps the hose 1, the hose 1 is deformed to separate the first port and the second port; when the tube clamping structure 2 releases the hose 1, the first port is connected to the second port.

[0025] The valve device of the present invention comprises a hose 1 and a tube clamping structure 2; the hose 1 is deformably arranged and has a first port and a second port that are interconnected; the tube clamping structure 2 is separately arranged from the hose 1, so that the hose 1 can be clamped or released by the tube clamping structure 2; when the tube clamping structure 2 clamps the hose 1, the hose 1 is deformed to separate the first port and the second port; when the tube clamping structure 2 releases the hose 1, the first port is connected to the second port. The tube clamping structure 2 can clamp or release the hose 1; when the tube clamping structure 2 clamps the hose 1, the hose 1 is deformed under the action of the tube clamping structure 2, so that the first port and the second port are separated, and the fluid inside the hose 1 is prevented from flowing between the first port and the second port; when the tube clamping structure 2 releases the hose 1, the hose 1 restores its shape, so that the first port and the second port are connected, so that the fluid inside the hose 1 can flow between the first port and the second port. Compared with other types of valves, the valve device with this structural design has the advantages of not being easy to clog and not being easy to stick, and when used in a fluid environment with high viscosity, it can effectively extend the life of the valve device. Furthermore, since the hose 1 and the clamping structure 2 are separately arranged, when the hose is blocked or damaged, the hose 1 can be replaced alone without operating the clamping structure 2, which effectively facilitates the maintenance of the valve device. The valve with the above structural design can well adapt to the control of high-viscosity fluids, solving the problem that the valve in the prior art is not suitable for use in high-viscosity fluid environments.

[0026] Specifically, the pipe clamping structure 2 includes: a rotary driving member 21 having a driving portion 211 rotatable about a predetermined axis; a sliding member 22 whose central axis is spaced from the predetermined axis; the rotary driving member 21 is connected to the sliding member 22 to drive the sliding member 22 to rotate about the predetermined axis; a fixed seat 23 provided with a first guiding structure 231 extending in a first direction; a movable seat 24, the movable seat 24 is engaged with the first guiding structure 231 and is movably arranged on the fixed seat 23 along the first direction to clamp or release the hose 1 through the movable seat 24 and the fixed seat 23; the movable seat 24 is provided with a second guiding structure 241 extending in a second direction, and the sliding member 22 is engaged with the second guiding structure 241; wherein, the first direction is different from the second direction.

[0027] The central axis of the sliding member 22 is spaced from the predetermined axis. That is to say, the sliding member 22 is arranged in an eccentric manner relative to the rotary driving member 21. When the driving portion 211 of the rotary driving member 21 rotates, it will drive the sliding member 22 to move along a circular track. Under the guiding action of the second guiding structure 241, the sliding member 22 can slide relative to the movable seat 24 along the second direction. Then, in cooperation with the guiding action of the first guiding structure 231, finally, the movable seat 24 can slide relative to the fixed seat 23 along the first direction. Since at least part of the hose 1 is located between the fixed seat 23 and the movable seat 24, when the fixed seat 23 and the movable seat 24 are relatively close to each other, the hose 1 can be clamped, thereby blocking the connection between the first port and the second port. When the fixed seat 23 and the movable seat 24 are relatively far from each other, the hose 1 can be released, thereby connecting the first port and the second port. By adopting the pipe clamping structure 2 with this structural design, a stable clamping effect can be achieved on the hose 1, which is beneficial to improving the reliability of the valve device.

[0028] In specific implementation, the angle between the first direction and the second direction can be any angle greater than 0° and less than 180°. Preferably, in order to ensure the driving effect on the movable seat 24, the first direction is perpendicular to the second direction.

[0029] In this embodiment, when the pipe clamping structure 2 clamps the hose 1, the central axis of the sliding member 22 and the predetermined axis are spaced along the first direction. In this way, the movable seat 24 can have a self-locking effect, that is, even if the rotary driving member 21 does not provide a driving force, the movable seat 24 can still maintain the position of clamping the hose 1, ensuring the clamping effect on the hose 1.

[0030] In specific implementation, the rotation driving member 21 can have various structural options, as long as it can achieve the rotation driving effect on the sliding member 22. For example, it can drive the driving part 211 to rotate through a motor and then drive the sliding member 22 to rotate, or it can also manually shake the driving part 211 to rotate and then drive the sliding member 22 to rotate.

[0031] In this embodiment, the rotation driving member 21 includes a motor. The driving part 211 is of a disc structure, and the disc structure is connected to the output shaft of the motor. The sliding member 22 is eccentrically arranged on the disc structure.

[0032] When the pipe clamping structure 2 clamps the hose 1, the central axis of the sliding member 22, the central axis of the hose 1, and the predetermined axis are in the same plane. That is to say, assuming there is a predetermined plane perpendicular to the predetermined axis, the positive projections of the predetermined axis, the central axis of the sliding member 22, and the central axis of the hose 1 on the predetermined plane are collinear. In this way, the reaction force exerted by the hose 1 on the movable seat 24 will not generate a component force in the direction perpendicular to the predetermined axis, thereby avoiding the relative separation of the movable seat 24 and the fixed seat 23 and ensuring a reliable clamping effect on the hose 1.

[0033] It should be noted that the central axis of the hose 1 refers to the central axis of the hose 1 in the non-deformed state. Even if it is deformed after being clamped by the pipe clamping structure 2, its central axis remains unchanged.

[0034] Specifically, the first guiding structure 231 is a first strip-shaped groove, and the movable seat 24 is slidably mounted in the first strip-shaped groove along the first direction; at least part of the hose 1 is located in the first strip-shaped groove; the second guiding structure 241 is a second strip-shaped groove, and the sliding member 22 is slidably mounted in the second strip-shaped groove along the second direction.

[0035] The sliding member 22 includes a rotating shaft and a rolling part. The rolling part is rotatably mounted on the rotating shaft; the rolling part is in rolling cooperation with the inner wall surface of the second strip-shaped groove.

[0036] By setting the sliding member 22 to include a rolling part, when it moves along the second strip-shaped groove in the second direction, the friction between it and the movable seat 24 can be reduced by the rolling of the rolling part, making the action of the pipe clamping structure 2 smoother.

[0037] Specifically, the rotation driving member 21 is arranged relative to the fixed seat 23 to be position-adjustable along the first direction.

[0038] By adopting the above setting, the installation position of the rotation driving member 21 on the fixed seat 23 can be adjusted, so as to drive the movable seat 24 to perform position adjustment along the first direction, and further play a role in adjusting the clamping effect on the hose 1, improving the flexibility of the use of the valve device.

[0039] To achieve the stable installation of the rotation driving member 21 and meet the position adjustment requirements, a strip-shaped hole 232 is provided on the fixed seat 23, and the strip-shaped hole 232 extends along the first direction; the rotation driving member 21 is connected to the fixed seat 23 through a connecting member passing through the strip-shaped hole 232; the connecting member is arranged to be position-adjustable along the extending direction of the strip-shaped hole 232.

[0040] Please refer to Figures 4 to 6 , the present invention also provides a mixing device, the mixing device includes: a mixing device 100 for mixing materials; the mixing device 100 has a discharge port; a valve device, the valve device is the above-mentioned valve device; the hose 1 of the valve device is connected to the discharge port. When the mixing device mixes the materials, the materials are discharged through the discharge port, and the discharge of the materials can be controlled by the valve device. When the mixed materials of the mixing device have characteristics such as high viscosity and high corrosiveness, the above-mentioned valve device can effectively improve the control effect of the discharge, reduce the failure risk, and improve the reliability of the use of the mixing device.

[0041] Specifically, the mixing device 100 is a dynamic mixer, and the dynamic mixer includes a dynamic mixing pipe 101, and the discharge port is arranged on the dynamic mixing pipe 101; wherein, the valve device is detachably installed on the dynamic mixing pipe 101. By detachably installing the valve device on the dynamic mixing pipe 101, the dynamic mixing pipe 101 can be conveniently replaced by disassembling the valve device.

[0042] Specifically, the valve device includes a connecting seat 3, and the connecting seat 3 includes: a first clamping portion and a second clamping portion, the first clamping portion and the second clamping portion are arranged at intervals, and a first mating surface is provided on the side of the first clamping portion facing the second clamping portion; a second mating surface is provided on the side of the second clamping portion facing the first clamping portion; a fastening member, the fastening member connects the first clamping portion and the second clamping portion, and the fastening member drives the first clamping portion and the second clamping portion to approach each other to clamp the dynamic mixing pipe 101 through the first mating surface and the second mating surface.

[0043] By adopting the above settings, the connecting seat 3 clamps the dynamic mixing pipe 101 with two clamping portions, so that the valve device can be stably installed on the dynamic mixing pipe 101 of the dynamic mixer, and the operation of disassembling the valve device from the dynamic mixing pipe 101 can be realized. Since the dynamic mixing pipe 101 is a vulnerable part, when the dynamic mixing pipe 101 is damaged, the connecting seat 3 can be separated from the dynamic mixing pipe by loosening the fastening member, so as to remove the valve device from the dynamic mixing pipe 101, which is convenient for replacing the dynamic mixing pipe 101.

[0044] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0045] The valve device of the present invention comprises a hose 1 and a tube clamping structure 2; the hose 1 is deformably arranged and has a first port and a second port that are interconnected; the tube clamping structure 2 is separately arranged from the hose 1, so that the hose 1 can be clamped or released by the tube clamping structure 2; when the tube clamping structure 2 clamps the hose 1, the hose 1 is deformed to separate the first port and the second port; when the tube clamping structure 2 releases the hose 1, the first port is connected to the second port. The tube clamping structure 2 can clamp or release the hose 1; when the tube clamping structure 2 clamps the hose 1, the hose 1 is deformed under the action of the tube clamping structure 2, so that the first port and the second port are separated, and the fluid inside the hose 1 is prevented from flowing between the first port and the second port; when the tube clamping structure 2 releases the hose 1, the hose 1 restores its shape, so that the first port and the second port are connected, so that the fluid inside the hose 1 can flow between the first port and the second port. Compared with other types of valves, the valve device with this structural design has the advantages of not being easy to clog and not being easy to stick, and when used in a fluid environment with high viscosity, it can effectively extend the life of the valve device. Furthermore, since the hose 1 and the clamping structure 2 are separately arranged, when the hose is blocked or damaged, the hose 1 can be replaced alone without operating the clamping structure 2, which effectively facilitates the maintenance of the valve device.
