Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The drainage bag is used as a simple disposable consumable, and the drainage bag is often used for saving the storage space in the storage process
Referring to fig. 1, the present invention provides a fluid one-way control structure 2, the main structure includes a cylindrical run-off channel 21, and one or more pairs of valve pieces 22 are fixed inside the run-off channel 21. The valve piece 22 in this embodiment may be made of hard polyethylene or elastic rubber. One end of the flap 22 is a fixed end 221 fixed to the inner wall of the radial flow channel. The fixed ends 221 of the pair of flap membranes 22 are sealed in registration and the free ends are oriented in the same direction. The direction of the free end with respect to the fixed end 221 at this time is the unidirectional flow direction of the fluid unidirectional control structure 2.
Referring to fig. 1 and 4, in order to improve the fluid sealing effect of the fluid one-way control structure 2 in the cut-off state, the cross section of the runoff stack 21 is set to be circular. The valve sheet 22 is correspondingly configured to be a half of an ellipse, and the purpose of this configuration is that the half-ellipse valve sheet 22 can enclose a half space of the runoff stack 21. The valve piece 22 with the pair of fixed ends 221 connected with each other can play a role of sealing the whole section of the radial flow channel 21.
As shown in fig. 2, since the material of the flap 22 is not an absolute rigid body, in the stop stressed state, in order to avoid the great deformation of the flap 22 due to the excessive static pressure, and reduce the tightness of the stop, a rib 222 may be provided on the flap 22, which extends from the fixed end 221 to the free end, to reduce the deformation of the flap 22 under the overall stressed condition while maintaining the elasticity of the flap 22. The sealing effect of the flap sheet 22 can be improved.
Referring to fig. 1 to 2, in order to improve the sealing effect of the valve membrane 22 on the radial flow channel 21, it is necessary to maintain the sealing effect of the valve membrane 22 under a stressed state, and it is necessary to maintain the outer edge of the valve membrane 22 to be attached to the inner diameter of the radial flow channel 21. When the tangent line of any point of the circumferential edge of the radial or inclined cross section of the runoff duct 21 is kept, the tangent line is not intersected with the circumferential edge of the radial or inclined cross section of the runoff duct 21. In this state, the distance from the fixed end 221 to the free end of the flap 22 can be shortened with the same sectional area, and the dispersion of the distance is low, so that the overall deformation degree of the flap 22 in a stressed state can be controlled, and the sealing effect of the flap 22 in an off state can be improved.
Referring to fig. 2 and 3, the mounting ring 23 is fixed to the inner wall of the runoff stack 21 in a sealing manner, and the valve piece 22 is fixed to the mounting ring 23. The mounting ring 23 is fixed with a cross bar 24, and the cross bar 24 is used for fixing the fixed end 221 of the flap sheet 22. In the production process, the valve piece 22 can be installed on the installation ring 23, assembly in the runoff stack 21 is not needed, and the production difficulty is reduced under the condition of keeping the sealing effect. The flap sheet 22 and the mounting ring 23 may be fixed in a split manner or may be integrally formed.
Referring to fig. 2 and 3, in order to facilitate the assembly of the mounting ring 23 and the runoff duct 21, the inner diameter of the runoff duct 21 may be processed to be greater than or equal to the outer diameter of the mounting ring 23, so that the mounting ring 23 can be slid into the runoff duct 21. The assembly is more convenient. After the installation ring 23 is assembled with the runoff stack 21, the relative position of the installation ring 23 needs to be kept fixed, especially the relative position of the installation ring 23 and the inner wall of the runoff stack 21 under the stress state of the valve piece 22 and the installation ring 23. The inner wall of the runoff stack 21 may be provided with a snap ring cover 211 which narrows in the axial direction, and the inner diameter of the narrowest part of the snap ring cover 211 is kept smaller than the outer diameter of the mounting ring 23. The snap ring cover 211 is fixed on the inner wall of the runoff stack 21 or is integrally formed with the runoff stack 21. The runoff stack 21 and the snap ring cover 211 are both made of elastic materials, and the mounting ring 23 can be mounted into the runoff stack 21 and can be kept fixed by opening the runoff stack 21 and the snap ring cover 211.
To show the shape of the valve piece 22, please refer to fig. 5 to 9, the fixed ends 221 of the two valve pieces 22 are overlapped, and the free ends extend in the same direction. In the forward flow state of the fluid, the free ends of the valve pieces 22 overlap and do not block the fluid. When the fluid flows in the reverse direction, the free ends of the valve flap 22 separate, blocking the fluid flow. The one-way control function of the fluid is realized.
When the fluid flows in the reverse direction, as shown in fig. 8, the cross section of the free end of the valve piece 22 may be configured as an arc, and the fluid enters the recess formed by the two arc free ends, so that the reverse fluid generates a reverse dynamic pressure on the two free ends. The free end of the pressing valve membrane 22 is in sealing contact with the inner wall of the runoff stack 21 to play a role of reverse stopping. Increasing the response speed of the reverse flow cutoff of the flap sheet 22.
Referring to fig. 10, the present solution further provides a directional jet generating structure, which includes an elastic bag cavity 3 and the above-mentioned fluid unidirectional control structure 2. The elastic sac cavity 3 comprises an inlet end and an outlet end which are communicated with the cavity body. A fluid one-way control structure 2 is disposed at the inlet end. And the free end of the valve piece 22 in the fluid one-way control structure 2 is oriented in the cavity of the elastic capsule cavity 3. The high-pressure fluid generated by the elastic capsule 3 in the stressed and contracted state can be ejected only through the outlet end to form directional jet flow.
Referring to fig. 11, in order to improve the working effect of the elastic bag cavity 3, one or more elastic rings 31 may be disposed on the inner wall of the elastic bag cavity 3. When the number of the elastic rings 31 is two, the two elastic rings 31 can be kept orthogonal to each other. Increasing the elasticity of the elastic capsule 3.
Referring to fig. 10 to 11, the present disclosure further provides a drainage bag, which includes a bag body 4 and a mouth-piece 1 connected by a hose 5, wherein the hose 5 is connected in series with the above-mentioned directional jet flow generating structure. In the implementation process, when the inner wall of the bag body 4 is adhered, the elastic bag cavity 3 is held and pressed, and high-pressure fluid is generated in the elastic bag cavity 3. Due to the blocking effect of the fluid one-way control structure 2, high-pressure fluid can only enter the bag body 4 through the outlet end of the elastic bag cavity 3 and can blow off the adhered inner wall of the bag body 4.
In order to save cost, the hose 5 is detachably communicated with the fluid one-way control structure 2 and the elastic bag cavity 3 in the scheme, can be connected when in use, and can be detached for standby after implementation.
As a complete application of the present solution, please refer to fig. 1 to 11, when the inner wall of the bag body 4 is adhered, the elastic bag cavity 3 is held and pressed, and high pressure fluid is generated in the elastic bag cavity 3. One or more pairs of valve pieces 22 are fixed inside the runoff stack 21, and one end of each valve piece 22 is a fixed end 221 and is fixed on the inner wall of the runoff passage. The fixed ends 221 of the pair of flap membranes 22 are overlapped and sealed, and the directions of the free ends are the same, so that the direction of the free ends relative to the fixed ends 221 at this time is the unidirectional flow direction of the fluid unidirectional control structure 2. The cross section of the runoff stack 21 is circular. The flap 22 is correspondingly configured as half of an ellipse. The valve piece 22 with the pair of fixed ends 221 connected with each other can play a role of sealing the whole section of the radial flow channel 21. The valve piece 22 is provided with a reinforcing rib 222 which is diverged from the fixed end 221 to the free end, so that the deformation amount of the valve piece 22 under the overall stress condition is reduced under the condition that the elasticity of the valve piece 22 is maintained. The sealing effect of the flap sheet 22 can be improved. The mounting ring 23 is fixed with the inner wall of the runoff stack 21 in a sealing way, and the valve piece 22 is fixed on the mounting ring 23. The cross bar 24 is fixed on the mounting ring 23, the cross bar 24 is used for fixing the fixed end 221 of the valve piece 22, the valve piece 22 is mounted on the mounting ring 23, and the valve piece 22 and the mounting ring 23 are integrally formed. The fixed ends 221 of the two pieces of flap membrane 22 are overlapped and the free ends thereof extend in the same direction. In the forward flow state of the fluid, the free ends of the valve pieces 22 overlap and do not block the fluid. When the fluid flows in the reverse direction, the free ends of the valve flap 22 separate, blocking the fluid flow. The one-way control function of the fluid is realized. The cross-section of the free end of the flap 22 may be curved, and the fluid enters the recess formed by the two curved free ends, and the reverse fluid generates a reverse dynamic pressure on the two free ends. The free end of the pressing valve membrane 22 is in sealing contact with the inner wall of the runoff stack 21 to play a role of reverse stopping. Increasing the response speed of the reverse flow cutoff of the flap plate 22. Therefore, the high-pressure fluid generated in the elastic bag cavity 3 can only enter the bag body 4 through the outlet end of the elastic bag cavity 3 and can blow off the adhered inner wall of the bag body 4. Through producing unidirectional efflux, solved the problem that the drainage bag inner wall vacuum adsorption or adhesion lead to being difficult to the separation.
