Description

Technical Field

[0001] This invention relates to the field of aquaculture pond technology, and in particular to an environmentally friendly, recyclable, and land-saving artificial mandarin fish aquaculture pond. Background Technology

[0002] As the core facility for artificial mandarin fish farming, the culture pond, with its advantages of being mobile and not occupying arable land, has become an ideal choice for high-density farming scenarios. Mandarin fish farming has extremely high requirements for dissolved oxygen levels in the water. Sufficient oxygen is crucial for ensuring the normal growth of mandarin fish and increasing farming density and survival rate. Therefore, continuously replenishing oxygen to the culture pond water is a core aspect of the farming process. Currently, the most common method for oxygenating the culture pond water is to use blowers to introduce air into the water. Specifically, multiple aerators are placed at the bottom of the culture pond to convert air into fine bubbles and release them evenly into the water, thus replenishing dissolved oxygen.

[0003] In traditional aeration systems, aeration heads are fixedly installed at the bottom of the aquaculture pond and are constantly underwater. When the blower stops operating, the water pressure in the pond acts on the aeration heads, causing water to backflow into the aeration pipes, filling both the pipes and the aeration heads with water. When restarting the blower, the equipment must first overcome the water pressure in the pipes and aeration heads to completely drain the water before air can be supplied to the water. This process subjects the blower to an extremely high load during startup, requiring more energy and causing severe impact on the blower's motor, impeller, and other core components. Prolonged operation under this high-load condition accelerates component wear, significantly increasing the probability of blower malfunctions. Frequent malfunctions not only interrupt aeration operations, affecting the survival environment of the mandarin fish, but also require additional manpower and maintenance costs, bringing numerous inconveniences and risks to high-density mandarin fish farming. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an environmentally friendly, recyclable and land-saving artificial mandarin fish farming pond to solve the problems mentioned in the background technology.

[0005] The technical solution of this invention: an environmentally friendly, recyclable, and land-saving artificial mandarin fish farming pond, comprising a pond body, a sewage discharge mechanism installed at one end of the pond body, a blower installed on the upper surface of the pond body near the sewage discharge mechanism, a rotatable hollow tube inserted into the air outlet end of the blower, the end of the hollow tube away from the blower being closed, a column arranged parallel to the hollow tube on the lower side of the hollow tube, the column being installed in the lower part of the pond body, multiple air outlet mechanisms evenly installed between the column and the hollow tube, and multiple sets of blocking mechanisms cooperating with the air outlet mechanisms to control the rotation range of the hollow tube installed in the lower part of the pond body. The parallel arrangement of hollow tubes and columns provides a stable installation base for the air outlet mechanism. The rotatable hollow tubes, combined with the blocking mechanism, enable the air outlet mechanism to operate flexibly within a preset range, ensuring uniform oxygenation coverage while preventing damage caused by excessive component movement. The coordinated design of the sewage discharge mechanism and the oxygenation mechanism simultaneously solves the problems of dissolved oxygen and pollution in the water, providing a basic condition for high-density aquaculture of mandarin fish. At the same time, the pond does not require fixed occupation of arable land, practicing the concept of saving land.

[0006] Preferably, the air outlet mechanism includes rubber rings, with multiple hollow rubber rings provided between the column and the hollow tube. An elastic silicone ring is installed inside each rubber ring, and the elastic silicone ring is sleeved between the column and the hollow tube. Multiple sets of connecting components are installed in a ring-shaped, equidistant area of ​​the hollow tube covered by the elastic silicone ring. A sealing component is provided inside the elastic silicone ring, fitting against its inner surface. A bent tube is installed on the outer surface of the rubber ring, with the end of the bent tube away from the rubber ring facing upwards. A one-way valve is installed at the end of the bent tube away from the rubber ring, and the one-way valve opens in the direction away from the bent tube. A hollow balloon, connected and fixed to the bent tube, is sleeved at the end of the bent tube near the one-way valve, and air is injected into the hollow balloon. The rubber and elastic silicone rings form a closed air chamber, which, together with the connecting components, enables air conduction. The upward-facing bend and the one-way valve design prevent water backflow into the aeration channel, avoiding the water accumulation problem of traditional aeration pipes and significantly reducing the start-up load of the blower. The buoyancy of the air inside the hollow bulb allows the bend to flexibly adjust its position according to the water level and airflow, ensuring that bubbles are evenly diffused to all layers of the water, improving dissolved oxygen efficiency. The flexibility of the elastic silicone rings adapts to the rotation of the hollow tube, ensuring a continuous and smooth aeration process and guaranteeing sufficient dissolved oxygen for the growth of mandarin fish.

[0007] Preferably, the connecting component includes branch pipes. Multiple branch pipes are installed in a ring-shaped, equidistant manner on the area of ​​the hollow tube covered by the elastic silicone ring. A pointed tip for piercing the elastic silicone ring is installed at the end of each branch pipe away from the hollow tube. Multiple vent holes are opened in a ring-shaped, equidistant manner on the end of each branch pipe near the pointed tip. A blocking ring is slidably installed inside each branch pipe. When the blocking ring is positioned with its pointed tip facing down, it blocks the vent holes. A limiting ring is installed inside the branch pipe on the side near the hollow tube to restrict the range of motion of the blocking ring. The pointed tip of the branch pipe can pierce the elastic silicone ring, enabling rapid connection between the hollow tube and the air chamber. The ring-shaped arrangement of vent holes ensures uniform air release. When the blocking ring is positioned with its pointed tip facing down, it automatically blocks the vent holes. The limiting ring restricts the range of motion of the blocking ring, preventing it from leaving its working position and ensuring stable switching between ventilation and blocking functions.

[0008] Preferably, the sealing assembly includes a guide plate, with a guide plate provided in a localized area inside the elastic silicone ring. The surface of the guide plate is close to the inner surface of the elastic silicone ring. Multiple support rods are installed on one side of the pool body, and the support rods are connected and fixed to the guide plate via connecting parts. The guide plate provides support in the area corresponding to the puncture of the elastic silicone ring by the tip of the support tube, preventing excessive outward expansion of this area under internal air pressure, thereby guiding the airflow to concentrate towards the bend and reducing lateral leakage. The fixing structure of the support rods and connecting parts keeps the guide plate stable.

[0009] Preferably, the blocking mechanism includes vertical plates. Multiple sets of vertical plates are evenly installed at the bottom of the pool body. A movable plate, cooperating with the vertical plate on the side near the column, is used to press down on the hollow spherical balloon. Two arms are hinged to the upper part of the movable plate facing the vertical plate. The ends of the arms away from the movable plate are connected and fixed to the vertical plate. A notch is provided on the upper part of the movable plate facing the vertical plate for moving the bent tube downwards. The upper end of the notch is open. A driving component is installed at the end of the bent tube near the rubber ring to move the lower end of the movable plate towards the vertical plate. The vertical plates and movable plates work together to limit the downward movement distance of the bent tube.

[0010] Preferably, the corner of the vertical plate facing the movable plate is machined with a first rounded corner, the corner of the movable plate facing the vertical plate is machined with a second rounded corner, and the edge of the notch is machined with a third rounded corner. The rounded corner design of the vertical plate, movable plate, and notch edges avoids scratching damage to the hollow balloon from sharp edges and corners, extending the service life of vulnerable parts.

[0011] Preferably, the drive assembly includes a horizontal plate. The end of the bent pipe near the rubber ring is fitted with a horizontal plate that is fixed to and connected to the bent pipe. Ear plates are installed at both ends of the horizontal plate. Two wedge plates that cooperate with the ear plates are installed on the side of the movable plate opposite to the vertical plate. The width of the wedge plates gradually increases from top to bottom. The cooperation of the horizontal plate, ear plates, and wedge plates, through the gradual width change of the wedge plates, allows the movable plate to tilt precisely when the bent pipe moves downward, forming a "V"-shaped space to press against the hollow spherical balloon, effectively limiting the downward depth of the bent pipe and ensuring that the one-way valve is always positioned upwards. Limiting can be achieved without additional power, simplifying the equipment structure while ensuring operational stability and reducing the probability of failure.

[0012] Preferably, rollers are rotatably mounted on the opposing surfaces of both ear plates, and these rollers make rolling contact with the wedge plate when the bend is within the notch. The rolling contact between the rollers on the ear plates and the wedge plate converts sliding friction into rolling friction, significantly reducing the resistance when the bend moves downward, making the tilting action of the movable plate smoother, and reducing component wear.

[0013] Preferably, the rubber ring is provided with first blocking rings on both sides of the end near the hollow tube. The first blocking rings are sleeved on the hollow tube and connected and fixed to the hollow tube. The first blocking rings provide bidirectional limiting for the end of the rubber ring near the hollow tube, preventing axial displacement of the rubber ring under rotation or air pressure, and ensuring the fitting accuracy between it and the hollow tube and column.

[0014] Preferably, the rubber ring is provided with second blocking rings on both sides of the end near the column. The second blocking rings are sleeved on the column and fixedly connected to it. The second blocking rings and the first blocking rings work together to limit the movement, ensuring that the rubber ring rotates stably between the hollow tube and the column, and preventing axial displacement from affecting the overall operation of the air outlet mechanism. The limiting structure also reduces the deformation of the rubber ring, ensures the stability of the air chamber shape, ensures smooth air conduction, and further improves the reliability of the aeration system.

[0015] Preferably, the sewage discharge mechanism includes a water level control box. The water level control box is installed on the upper part of the side of the pool near the blower. The upper end of the water level control box is open. A sewage discharge pipe and a connecting pipe are installed at the bottom of the water level control box. One end of the connecting pipe extends into the lower part of the water level control box, and the end of the connecting pipe inside the water level control box is connected to a water level control pipe. The upper end of the water level control pipe extends to the upper side of the water level control box. The end of the connecting pipe away from the water level control pipe is connected to a collection pipe. Multiple fish toilets are evenly installed on the side of the pool near the column. The fish toilets are connected to the collection pipe via straight pipes. The fish toilets collect the feces and uneaten food of the mandarin fish and quickly transport them to the water level control box through the straight pipes and collection pipes, preventing pollutants from accumulating at the bottom of the pool and causing water quality deterioration. The water level control pipe can flexibly adjust the sewage discharge height to achieve sewage discharge.

[0016] Preferably, both the sewage pipe and the connecting pipe are L-shaped, with the end of the sewage pipe furthest from the water level control box arranged horizontally. The L-shaped sewage pipe and connecting pipe facilitate installation and layout, implement the concept of environmentally friendly circular aquaculture, and reduce the aquaculture risks caused by water quality deterioration.

[0017] Preferably, a bottom frame is installed at the bottom of the pool body, and an opening is provided on the side of the bottom frame near the water level control box. The lower end of the opening is open, and the end of the connecting pipe away from the water level control box passes through the opening. The bottom frame enhances the overall structural strength of the pool body, improves its load-bearing capacity and stability, and adapts to the needs of mobile deployment; the opening design provides a convenient installation channel for the connecting pipe.

[0018] Preferably, the upper part of the pool is equipped with a protective edge, and the lower surface of the protective edge is equipped with multiple evenly distributed reinforcing ribs. The lower ends of the reinforcing ribs are connected and fixed to the bottom frame, and the reinforcing ribs are also connected and fixed to the pool body. The protective edge provides protection for the upper part of the pool body, preventing water from overflowing or mandarin fish from jumping out during the breeding process, while also providing a safe working edge for operators. The reinforcing ribs connect the protective edge and the bottom frame, forming a three-dimensional reinforced structure, which greatly improves the deformation resistance and stability of the pool body and extends its service life.

[0019] Preferably, a shaft is installed at the end of the hollow tube furthest from the blower. The shaft is arranged parallel to the hollow tube, and a limiting sleeve is fitted onto the end of the shaft furthest from the hollow tube, making slidable contact with the shaft. The end of the limiting sleeve furthest from the hollow tube is closed, and the limiting sleeve is connected and fixed to the edge guard. The sliding fit between the shaft and the limiting sleeve provides support for one end of the hollow tube without affecting its rotation.

[0020] Preferably, the cross-sections of the edge protector, the pool body, and the bottom frame are all rectangular.

[0021] The beneficial effects of this invention are:

[0022] The one-way valve only conducts in the direction away from the bend, which can effectively prevent water from flowing back into the hollow pipe, branch pipe and other ventilation channels, avoiding the problem of water accumulation in the aeration pipe. When the blower starts, it does not need to overcome water pressure to discharge the accumulated water, which greatly reduces the starting load, reduces the impact damage to core components such as motor and impeller, reduces the probability of failure, and ensures continuous and stable oxygenation operation.

[0023] Initially, the bend is submerged in water within the pool. When the blower operates, airflow enters the hollow tube. The air inside the hollow tube then enters the space formed by the rubber and elastic silicone rings through channels created by branch pipes and vents. The air then flows back into the water within the pool. At this point, the bend moves downwards, causing the structure formed by the rubber and elastic silicone rings to rotate around the hollow tube and column. Simultaneously, the hollow tube rotates with this structure, causing multiple pointed branch pipes to alternately pierce the elastic silicone rings. This ensures that the space formed by the rubber and elastic silicone rings remains connected to the internal space of the hollow tube without affecting the bend's downward movement to the bottom of the pool. When the blower unexpectedly stops, the buoyancy of the hollow bulb causes the bend to move upwards to the upper part of the pool, reducing the depth of the one-way valve in the water. This reduces the resistance required to open the one-way valve when the blower is restarted.

[0024] When the bend moves the hollow balloon downwards between the vertical plate and the movable plate, the rollers on the horizontal plate press against the wedge plate, causing the lower end of the movable plate to tilt towards the vertical plate. At this time, the movable plate and the vertical plate form a V-shaped space that is wider at the top and narrower at the bottom. The lower part of this space mechanically limits the hollow balloon, thereby reliably restricting the downward movement depth of the hollow balloon and its bend, ensuring that the end of the bend where the one-way valve is installed is always arranged upwards.

[0025] By setting a fixed guide plate inside the elastic silicone ring, local support is provided for the area of ​​the elastic silicone ring that has been punctured by the sharp tip when it rotates to that point. This effectively prevents the area from expanding outward under the internal air pressure, thereby guiding the airflow to concentrate and discharge from the one-way valve at the end of the bend, thus improving the aeration efficiency.

Under the water pressure of the pool 100, the mandarin fish feces and uneaten food collected by the fish toilet are quickly transported to the water level control box 300 through the straight pipe 3032 and the collection pipe 3031. Then, the water in the water level control box 300 is discharged through the sewage pipe 302 to avoid pollutants accumulating at the bottom of the pool and causing water quality deterioration.

[0047] A blower 200 is installed on the upper surface of the pool body 100 near the water level control box 300. A rotatable hollow tube 201 is inserted into the air outlet end of the blower 200, with the end of the hollow tube 201 away from the blower 200 being closed. A shaft 203 is installed at the end of the hollow tube 201 away from the blower 201, and the shaft 203 is arranged parallel to the hollow tube 201.

The second blocking ring 2021 is sleeved on the column 202 and connected and fixed to the column 202. The second blocking ring 2021 and the first blocking ring 2011 work together to limit the movement of the rubber ring belt 500, ensuring that the rubber ring belt 500 rotates stably between the hollow tube 201 and the column rod 202, avoiding axial displacement, reducing the deformation of the rubber ring belt 500, ensuring the stability of the air chamber shape, ensuring smooth air conduction, and improving the reliability of the aeration system.

[0049] An elastic silicone ring 504 is installed inside the rubber ring 500, and the elastic silicone ring 504 is sleeved between the column rod 202 and the hollow tube 201. Multiple branch pipes 800 are installed in a ring at equal intervals in the area of ​​the hollow tube 201 covered by the elastic silicone ring 504. A pointed tip 801 for piercing the elastic silicone ring 504 is installed at the end of the branch pipe 800 away from the hollow tube 201. Multiple vent holes 804 are opened in a ring at equal intervals at the end of the branch pipe 800 near the pointed tip 801. A blocking ring 802 is slidably installed inside the branch pipe 800. When the pointed tip 801 is arranged downwards, the blocking ring 802 blocks the vent holes 804. A limiting ring 803 for limiting the range of motion of the blocking ring 802 is installed inside the branch pipe 800 near the hollow tube 201. The tip 801 of the branch pipe 800 can pierce the elastic silicone ring 504, enabling rapid connection between the hollow pipe 201 and the air chamber. The annularly arranged vent holes 804 ensure uniform air release. When the tip 801 is facing down, the blocking ring 802 automatically blocks the vent holes 804. The limiting ring 803 restricts the range of motion of the blocking ring 802, preventing it from leaving the working position and ensuring stable switching between ventilation and blocking functions.

[0050] A guide plate 600 is provided at a localized location on the inner side of the elastic silicone ring 504. The guide plate 600 is fixed to the inner wall of the pool body 100 by a support rod 601 and a connecting part 6011. Its surface maintains a small gap or sliding contact with the inner surface of the rotating elastic silicone ring 504. When the tip 801 of the branch pipe 800 punctures the elastic silicone ring 504 and rotates to the area where the guide plate 600 is located, the guide plate 600 can provide support to prevent the puncture point from opening excessively under internal air pressure, thereby ensuring that the airflow is mainly discharged through the bend pipe 503. Plate 600 is an elastic arc-shaped guide plate, which is fixed to the inner wall of pool 100 by support rod 601 and connecting part 6011; the concave surface of the arc-shaped guide plate maintains sliding contact with the inner surface of the rotating elastic silicone ring 504; when the tip 801 of branch pipe 800 pierces the elastic silicone ring 504 and rotates to the area close to guide plate 600, under the constraint of arc-shaped guide plate, the pierced elastic silicone ring area cannot bulge outward fully under the action of air pressure inside the air chamber, thereby effectively guiding the air to mainly flow towards the bend 503 and reducing lateral leakage.

[0051] A bend 503 is installed on the outer surface of the rubber ring belt 500, with the end of the bend 503 away from the rubber ring belt 500 facing upwards. A one-way valve 501 is installed on the end of the bend 503 away from the rubber ring belt 500, and the one-way valve 501 is open in the direction away from the bend 503. The one-way valve 501 is only open in the direction away from the bend 503, which can effectively prevent water from flowing back into the air passages such as the hollow pipe 201 and the branch pipe 800, avoiding the problem of water accumulation in the aeration pipe. When the blower 200 starts, it does not need to overcome water pressure to discharge accumulated water, which greatly reduces the starting load, reduces the impact damage to core components such as motors and impellers, reduces the probability of failure, and ensures continuous and stable oxygenation operation.

[0052] A hollow balloon 502, which is connected and fixed to the bent tube 503, is fitted onto one end of the bent tube 503 near the rubber ring band 500. The hollow balloon 502 is filled with air. The inner circumferential surface of the rubber ring band 500 and the outer circumferential surface of the elastic silicone ring band 504 are bonded and fixed along their annular edges with sealant, thereby forming a closed annular air cavity 505 that surrounds the column rod 202 and the hollow tube 201 between the two. The proximal end of the bent tube 503 passes through and is sealed to the rubber ring band 500, and communicates with the inside of the annular air cavity. Multiple sets of vertical plates 400 are evenly installed at the bottom of the pool body 100. On the side of the vertical plate 400 near the column rod 202, there is a movable plate 401 that cooperates with the vertical plate 400 to hold the hollow balloon 502. Two arms 4011 are hinged to the upper part of the side of the movable plate 401 facing the vertical plate 400. The end of the arm 4011 away from the movable plate 401 is connected and fixed to the vertical plate 400. A notch 4012 is opened at the upper part of the side of the movable plate 401 facing the vertical plate 400 to allow the bent tube 503 to move downward. The upper end of the notch 4012 is open. Initially, the bend 503 is submerged in water within the pool 100. When the blower 200 operates, airflow enters the hollow tube 201. Subsequently, the air within the hollow tube 201 enters the space formed by the rubber ring 500 and the elastic silicone ring 504 through channels formed by the branch pipe 800 and vent 804. Then, the air within this space flows into the water within the pool 100 through the channel formed by the bend 503 and the one-way valve 501. At this point, the bend 503 moves downwards, causing the structure formed by the rubber ring 500 and the elastic silicone ring 504 to rotate around the hollow tube 201 and the column 202. Simultaneously, the air... The core tube 201 rotates synchronously with it, and multiple branch tubes 800 with pointed tips 801 alternately pierce the elastic silicone ring band 504. Without affecting the downward movement of the bent tube 503 to the bottom of the pool body 100, the space formed by the rubber ring band 500 and the elastic silicone ring band 504 is always connected with the internal space of the hollow tube 201. When the blower 200 stops unexpectedly, the airflow from the one-way valve 501 stops. At this time, under the buoyancy of the hollow balloon 502, the bent tube 503 and the one-way valve 501 move upward to the upper position inside the pool body 100, so that the depth of the one-way valve 501 in the water is reduced, and the resistance to opening the one-way valve 501 is reduced when the blower 200 is restarted.

[0053] The vertical plate 400 has a first rounded corner at the corner facing the movable plate 401, the movable plate 401 has a second rounded corner at the corner facing the vertical plate 400, and the edge of the notch 4012 has a third rounded corner. The design of the first, second, and third rounded corners reduces the wear of the vertical plate 400 and the movable plate 401 on the hollow balloon 502. A horizontal plate 700 is fitted onto one end of the bent tube 503 near the rubber ring belt 500 and is fixed to the bent tube 503. Both ends of the horizontal plate 700 are equipped with ear plates 7011. Two wedge plates 402 that cooperate with the ear plates 7011 are installed on the side of the movable plate 401 away from the vertical plate 400. The width of the wedge plates 402 gradually increases from top to bottom. Rollers 701 are rotatably installed on the opposite sides of the two ear plates 7011. The rollers 701 roll in contact with the wedge plates 402 when the bent tube 503 is inside the notch 4012. When the bend 503 moves the hollow balloon 502 downwards to between the vertical plate 400 and the movable plate 401, the horizontal plate 700 moves along with the bend 503. Therefore, the roller 701 on the horizontal plate 700 will squeeze the wedge plate 402, causing the lower end of the movable plate 401 to tilt towards the vertical plate 400. At this time, the movable plate 401 and the vertical plate 400 form a V-shaped space that is wider at the top and narrower at the bottom. The lower part of this space blocks and constrains the hollow balloon 502 that continues to move downwards, thereby limiting the downward movement depth of the hollow balloon 502 and the bend 503 connected to it, so that the end of the bend 503 where the one-way valve 501 is installed is always arranged upwards.

[0054] Working principle of the invention:

[0055] After the blower 200 is started, air enters the rotatable hollow tube 201 through the plug-in connection. The one-way valve 501 at the end of the bend 503 only conducts air away from the bend 503. Combined with the buoyancy of the air inside the hollow balloon 502, a double anti-backflow mechanism is formed to prevent water from entering the ventilation channels such as the hollow tube 201 and the branch pipe 800, ensuring that the ventilation path is dry and unobstructed.

[0056] Air inside the hollow tube 201 is conducted through the annularly arranged branch pipe 800. The pointed end 801 of the branch pipe 800 punctures the elastic silicone ring 504, allowing air to enter the closed air chamber formed by the rubber ring 500 and the elastic silicone ring 504. At this time, the plugging ring 802 inside the branch pipe 800 detaches from the vent 804 under the action of gravity. The air then passes through the vent 804, the air chamber, and the bend 503, and is finally released into the water through the one-way valve 501, forming tiny bubbles to replenish dissolved oxygen.

[0057] The reaction force generated by the release of air causes the bent tube 503 to move downwards and drives the annular integral structure, which is sealed and connected by the rubber ring belt 500 and the elastic silicone ring belt 504, to rotate around the hollow tube 201 and the column 202. The hollow tube 201 rotates synchronously. Multiple branch pipes 800 alternately puncture the elastic silicone ring belt 504 as they rotate. Because the elastic silicone ring belt 504 has self-sealing elasticity, when the tip 801 of the branch pipe 800 rotates away, the puncture hole will close by itself, while the currently aligned branch pipe remains connected, thereby ensuring that the annular air chamber is always connected to the inside of the hollow tube 201, realizing all-round and uniform aeration of the aquaculture pond water.

[0058] During the downward movement of the bend 503, the rollers 701 at both ends of the horizontal plate 700 roll into contact with the wedge plate 402, pushing the movable plate 401 to tilt towards the vertical plate 400, forming a "V"-shaped space to press down the hollow balloon 502, limiting the downward depth of the bend 503 and ensuring that the one-way valve 501 always faces upward; when the blower 200 stops, the buoyancy of the hollow balloon 502 drives the bend 503 to float to the upper part of the water, reducing the water depth of the one-way valve 501 and reducing resistance for the next start-up.

[0059] During rotation, the inner side of the elastic silicone ring 504 slides in contact with the fixed elastic arc-shaped guide plate 600. When the area with the piercing hole rotates to the guide plate 600, the guide plate 600 applies radial constraint to it to prevent excessive expansion under internal air pressure, thus ensuring the guidance of the airflow path and allowing the airflow to be discharged more concentratedly through the bend 503 and the one-way valve 501.

[0060] When the area of ​​the elastic silicone ring 504 pierced by the tip 801 rotates to the vicinity of the fixed guide plate 600, the guide plate 600 constrains it, preventing it from over-expanding under the air pressure of the air chamber, and ensuring that the airflow is guided to the bend 503 and the one-way valve 501.
