Description

Technical Field

[0001] This invention relates to the field of drinking water sterilization technology, specifically to a flow-through UV ultraviolet sterilization device for drinking water storage tanks. Background Technology

[0002] With the development of society and economy, people are paying more and more attention to their own and their families' health. In our daily lives, the health of drinking water has an important impact on people's health. Therefore, the standards and requirements for the sterilization of drinking water are constantly being raised.

[0003] Patent CN215479881U discloses a flow-through UV ultraviolet sterilization device for drinking water, belonging to the field of drinking water sterilization. It includes a water storage tank, a sterilization component, and a water circulation component. The sterilization component is detachably fixed to one end opening of the water storage tank, and has an inlet on one side communicating with the water storage tank. The water circulation component is detachably fixed to the other end opening of the water storage tank, and has an outlet on one side communicating with the water storage tank. The sterilization component includes a radiator detachably fixed to one end opening of the water storage tank. The inlet is located at the center of one side of the radiator, and an annular cavity is formed around the inlet inside the radiator. A driving power supply is fixedly connected inside the annular cavity. Multiple UVC-LED light sources are fixed along the inlet on the side of the radiator near the water storage tank. By using the water circulation component, the water flow can be improved to achieve prolonged water retention and a circulating sterilization effect.

[0004] However, the device still has shortcomings: the device achieves circulating sterilization by improving water flow, but when the water flows into the storage tank, it is easy to carry dirt such as mud and sand due to poor filtration. It is difficult to remove them effectively in the subsequent ultraviolet sterilization process. Moreover, the dirt such as mud and sand settles inside the storage tank for a long time, which can easily aggravate the oxidation and pollution of the storage tank and sterilization mechanism, and can easily lead to a gradual decrease in sterilization effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a flow-through UV sterilization device for drinking water storage tanks, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flow-through UV sterilization device for drinking water storage tanks, comprising a water storage mechanism, a sterilization mechanism on the right side of the water storage mechanism, a U-shaped quartz tube on the left side of the sterilization mechanism, a straight quartz tube inside the U-shaped quartz tube, a water filtration mechanism on the left side of the water storage mechanism, an anti-impact device to protect the sterilization mechanism on the right side of the water filtration mechanism, an anti-water accumulation device to reduce water residue on the right side of the anti-impact device, several UV components equidistantly and fixedly installed inside the right end of the water filtration mechanism, a filter plate fixedly installed inside the water filtration mechanism, an electric slide rail fixedly installed on the inner wall of the left end of the water filtration mechanism, several sliding blocks equidistantly and fixedly installed inside the electric slide rail, a baffle plate fixedly installed at the end of each sliding block away from the electric slide rail, a friction roller fixedly installed inside the groove of the baffle plate, and a connecting rod fixedly installed at the end of the baffle plate away from the electric slide rail.

[0007] According to the above technical solution, the sterilization mechanism sterilizes drinking water to ensure drinking water safety. The U-shaped quartz tube is located inside the water storage mechanism. The U-shaped quartz tube reflects ultraviolet light. The outer wall of the U-shaped quartz tube is symmetrically provided with water inlets. The right end of the straight quartz tube is fixedly installed on the left side of the sterilization mechanism.

[0008] According to the above technical solution, the outer wall of the left end of the water filtration mechanism is spirally designed, and the water filtration mechanism is used to connect and transport water sources. The ultraviolet component and the sterilization mechanism work together to improve the sterilization effect on drinking water. The electric slide rail is located on the left side of the filter plate. The baffle plate achieves revolution movement through the power source provided by the electric slide rail. The baffle plate has a groove on the side near the filter plate. The outer wall of the friction roller contacts the left surface of the filter plate. The outer wall of the connecting rod moves through the interior of the filter plate, screwing the water filtration mechanism into the water source installation location through the spiral groove. When the water source passes through the water filtration mechanism and enters the water storage mechanism, it will contact the filter plate. The filter plate blocks dirt such as sediment in the water, preventing dirt from entering the water storage mechanism at the same time. Subsequently, the water source is sterilized by UV light irradiated by the ultraviolet component. After the water source enters the water storage mechanism, it is further sterilized by… The U-shaped quartz tube's U-shaped cotton diverts and circulates the water, extending the water's residence time within the storage mechanism. Simultaneously, the U-shaped and straight quartz tubes reflect ultraviolet light. Water then enters through the inlet of the U-shaped quartz tube and exits through the straight quartz tube and sterilization mechanism. Before water intake begins, the electric slide rail is activated, driving the sliding block to revolve within itself. This revolve drives the baffle plate to revolve, diverting the water and preventing it from continuously flowing across the filter plate surface in a single area. As the baffle plate revolves, it drives the friction roller to rub along the filter plate surface. Simultaneously, the baffle plate drives the connecting rod to rotate. During this process, the friction roller rotates within the baffle plate's groove due to friction, continuously wiping the filter plate surface during its revolve and rotation to prevent dirt in the water from adhering to and solidifying on the filter plate surface for extended periods.

[0009] According to the above technical solution, the anti-impact device includes a transmission rod, the left end of which is fixedly installed on the right end of a connecting rod. A non-self-locking reciprocating spiral groove is provided on the outer wall of the right end of the transmission rod. A spiral blade is fixedly installed through the outer wall of the transmission rod. The spiral blade conveys the water source in a spiral manner to reduce its speed. The spiral blade is located inside the water filtration mechanism. When the connecting rod rotates, it drives the transmission rod to rotate. The transmission rod drives the spiral blade to revolve inside the water filtration mechanism. When the spiral blade revolve, it makes spiral contact with and conveys the water source entering the water filtration mechanism.

[0010] According to the above technical solution, a sliding ring is slidably installed through the outer wall of the reciprocating spiral groove of the transmission rod, and a heating mechanism is fixedly installed at equal intervals on the outer wall of the sliding ring. A limit ring is fixedly installed at the end of the heating mechanism away from the sliding ring, and a semi-circular shell is fixedly installed on the right side of the limit ring.

[0011] According to the above technical solution, the heating mechanism is used to initially heat the water source to optimize the sterilization effect. The outer wall of the limiting ring is slidably installed on the inner wall of the water storage mechanism. The semi-circular shell prevents the water source from flowing back through its own arc surface. When the transmission rod rotates, it drives the sliding ring to slide towards the U-shaped quartz tube and reset through the non-self-locking reciprocating spiral groove on its outer wall. This process is repeated. At the same time, the sliding ring drives the heating mechanism to move synchronously. During the movement of the heating mechanism, it changes its own heating orientation to avoid the phenomenon of continuous heating in a single area inside the water storage mechanism. During the horizontal movement and reset of the heating mechanism, it drives the limiting ring to slide along the inside of the water storage mechanism. The limiting ring drives the semi-circular shell to move synchronously. The water source stored on the concave surface of the semi-circular shell is effectively heated by the heating mechanism. At the same time, the arc surface of the semi-circular shell intercepts the water source flowing into the water storage mechanism.

[0012] According to the above technical solution, the anti-water accumulation device includes a hollow plate. The hollow plate is fixedly installed on the outer wall of the limiting ring at one end near the heating mechanism. A circular ring plate is fixedly installed on the other end of the hollow plate away from the limiting ring. A rotating rod is fixedly installed on the left side of the sterilization mechanism. The outer wall of the spiral groove of the rotating rod is penetrated and movably installed inside the circular ring plate. Activated carbon plates are fixedly installed at equal intervals on the outer wall of the rotating rod.

[0013] According to the above technical solution, the outer wall of the annular plate is slidably installed on the inner wall of the water storage mechanism. The rotating rod is located outside the water inlet of the U-shaped quartz tube. A non-self-locking spiral groove is opened at one end of the rotating rod near the annular plate. The activated carbon plate further optimizes the water quality on the original basis. When the limiting ring moves horizontally, it drives the hollow plate to move synchronously. The hollow plate pushes the annular plate to move synchronously along the inside of the water storage mechanism. When the annular plate moves horizontally, it will pass through the outer wall of the rotating rod with the non-self-locking spiral groove. The limiting of the spiral groove causes the rotating rod to generate a rotational force. When the rotating rod rotates on the outer wall of the sterilization mechanism, the rotating rod will drive the activated carbon plate to revolve. When the activated carbon plate revolve, it makes full contact with the water entering the U-shaped quartz tube.

[0014] According to the above technical solution, the anti-water accumulation device also includes a fixed arc shell. The outer wall of the fixed arc shell is fixedly installed on the inner wall of the water storage mechanism. The right side of the fixed arc shell contacts the left edge of the sterilization mechanism. Arc-shaped blocks are fixedly installed at equal intervals on the inner wall of the fixed arc shell. Arc-shaped filter cotton is fixedly installed on the inner wall of the right end of the fixed arc shell. The left end of the arc-shaped filter cotton contacts the right side of the circular ring plate. The outer wall of the arc-shaped filter cotton is fixedly connected to the surface of the arc-shaped block. The arc-shaped filter cotton acts to intercept tiny impurities in the water. When the circular ring plate moves horizontally, it pushes the arc-shaped filter cotton. The arc-shaped filter cotton generates a force of motion and is limited by the fixed arc shell. At this time, the arc-shaped filter cotton deforms due to the thrust of the circular ring plate. At the same time, the arc-shaped filter cotton is limited by the arc-shaped block, causing it to form multiple stress points. Thus, the deformation process is multi-segment deformation. After the water intake operation is completed, the electric slide rail extends its operation for a period of time, that is, it extends the squeezing movement of the arc-shaped filter cotton.

[0015] This invention provides a flow-through UV sterilization device for drinking water storage tanks. It has the following beneficial effects:

[0016] (1) The present invention uses a U-shaped quartz tube, a straight quartz tube, a water filtration mechanism, an ultraviolet component, a filter plate, an electric slide rail, a sliding block, a baffle plate, a friction roller and a connecting rod to effectively intercept dirt such as mud and sand through the filter plate, preventing them from settling inside the water storage mechanism for a long time, avoiding pollution of the water storage mechanism and the sterilization mechanism, which would lead to a gradual decrease in the sterilization effect. At the same time, the water source can be fully exposed to ultraviolet light to optimize the sterilization effect and ensure drinking water health. Through the revolution of the baffle plate, the filter plate is made to contact the water source evenly as a whole, so as to prevent the excessive use of the local area of ​​the filter plate, which would cause the local filter holes to be blocked and reduce the inflow velocity. At the same time, the friction roller effectively prevents dirt from adhering and solidifying on the surface of the filter plate, accelerating its oxidation rate and shortening the service life.

[0017] (2) The present invention uses an anti-impact device, which works in conjunction with a connecting rod, transmission rod, spiral blade, sliding ring, heating mechanism, limiting ring and semi-circular shell. The spiral blade contacts and transports the water source, which slows down the water source and prevents the water source from flowing straight in and impacting the U-shaped quartz tube, thus reducing the possibility of the U-shaped quartz tube breaking during long-term use. The heating mechanism effectively heats the spirally flowing water source, which increases the activity of water molecules inside the water source. Combined with ultraviolet light irradiation, the sterilization effect of the water source is improved on the original basis, reducing microbial residue. The semi-circular shell guides the water source through the outer arc surface, preventing the water source from flowing back.

[0018] (3) The present invention, through the setting of the anti-water accumulation device, through the cooperation of the limiting ring, hollow plate, circular ring plate, rotating rod, activated carbon plate, fixed arc shell, arc block and arc filter cotton, the activated carbon plate, through the revolution, continuously makes full contact with the water source, and relies on the activated carbon to fully purify the harmful substances contained in the water source, while avoiding the harmful substances remaining and causing odor to grow inside the water storage mechanism and contaminating the drinking water; through the deformation and reset of the arc block, the water source flowing into the U-shaped quartz tube continues to be squeezed, absorbed and discharged. In this process, the tiny impurities or floating objects in the water are absorbed and the water source is discharged, improving the purity of the water source on the original basis, and avoiding the inside of the quartz tube being contaminated.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Please see Figures 1-8 One embodiment of the present invention is: a flow-through UV ultraviolet sterilization device for drinking water storage tanks, comprising a water storage mechanism 1, a sterilization mechanism 2 disposed on the right side of the water storage mechanism 1, a U-shaped quartz tube 3 disposed on the left side of the sterilization mechanism 2, a straight quartz tube 4 disposed inside the U-shaped quartz tube 3, a water filtration mechanism 5 disposed on the left side of the water storage mechanism 1, an anti-impact device 13 for protecting the sterilization mechanism 2 disposed on the right side of the water filtration mechanism 5, an anti-water accumulation device 14 for reducing water residue disposed on the right side of the anti-impact device 13, a plurality of ultraviolet components 6 are equidistantly and fixedly installed inside the right end of the water filtration mechanism 5, a filter plate 7 is fixedly installed inside the water filtration mechanism 5, an electric slide rail 8 is fixedly installed on the inner wall of the left end of the water filtration mechanism 5, a plurality of sliding blocks 9 are equidistantly and fixedly installed inside the electric slide rail 8, a baffle plate 10 is fixedly installed at the end of the sliding block 9 away from the electric slide rail 8, a friction roller 11 is fixedly installed inside the slide groove of the baffle plate 10, and a connecting rod 12 is fixedly installed at the end of the baffle plate 10 away from the electric slide rail 8.

[0030] The sterilization mechanism 2 sterilizes drinking water to ensure drinking water safety. The U-shaped quartz tube 3 is located inside the water storage mechanism 1. The U-shaped quartz tube 3 reflects ultraviolet light. The outer wall of the U-shaped quartz tube 3 is symmetrically provided with water inlets. The right end of the straight quartz tube 4 is fixedly installed on the left side of the sterilization mechanism 2.

[0031] The outer wall of the left end of the water filtration mechanism 5 is spirally designed, and the water filtration mechanism 5 is used to connect and transport water sources. The ultraviolet component 6 and the sterilization mechanism 2 work together to improve the sterilization effect on drinking water. The electric slide rail 8 is located on the left side of the filter plate 7. The baffle 10 achieves revolution movement through the power source provided by the electric slide rail 8. The baffle 10 has a groove on the side near the filter plate 7. The outer wall of the friction roller 11 contacts the left surface of the filter plate 7. The outer wall of the connecting rod 12 moves through the interior of the filter plate 7.

[0032] The filter plate 7 effectively intercepts dirt such as silt, preventing it from settling inside the water storage mechanism 1 for a long time. This avoids contamination of the water storage mechanism 1 and the sterilization mechanism 2, which would gradually reduce the sterilization effect. At the same time, the water source can be fully exposed to ultraviolet light to optimize the sterilization effect and ensure drinking water health. The rotation of the baffle plate 10 ensures that the filter plate 7 is in uniform contact with the water source, preventing excessive use of local areas of the filter plate 7, which would cause local filter pore blockage and reduce the inflow velocity. Meanwhile, the friction roller 11 effectively prevents dirt from adhering to and solidifying on the surface of the filter plate 7, accelerating its oxidation rate and shortening the service life.

[0033] In use, the water filtration mechanism 5 is screwed into the water source installation location through the spiral groove. When the water source passes through the water filtration mechanism 5 into the water storage mechanism 1, it will come into contact with the filter plate 7. The filter plate 7 blocks dirt such as sediment in the water, preventing dirt from entering the water storage mechanism 1 simultaneously. Subsequently, the water source is sterilized by UV light irradiated by the ultraviolet component 6. After the water source enters the water storage mechanism 1, it is diverted and circulated through the U-shaped cotton of the U-shaped quartz tube 3, extending the residence time of the water source inside the water storage mechanism 1. At the same time, the U-shaped quartz tube 3 and the straight quartz tube 4 reflect the ultraviolet light. Then, the water source enters through the inlet of the U-shaped quartz tube 3 and then passes through the straight quartz tube 4. Pipe 4 is discharged from the sterilization mechanism 2; before the water intake begins, the electric slide rail 8 is activated. The electric slide rail 8 drives the sliding block 9 to revolve inside itself. When the sliding block 9 revolves, it drives the baffle 10 to revolve. When the baffle 10 revolves, it disperses the water source to prevent the water source from continuously and in a single area from flowing across the surface of the filter plate 7. When the baffle 10 revolves, it drives the friction roller 11 to revolve and rub along the surface of the filter plate 7. At the same time, the baffle 10 drives the connecting rod 12 to rotate. During this process, the friction roller 11 rotates inside the slide groove of the baffle 10 by relying on friction. The friction roller 11 continuously wipes the surface of the filter plate 7 during its revolving and rotating process to prevent dirt in the water from adhering to and solidifying on the surface of the filter plate 7 for a long time.

[0034] According to the above embodiments, the filter plate 7 effectively intercepts dirt such as silt and sand, preventing it from settling inside the water storage mechanism 1 for a long time. This avoids contamination of the water storage mechanism 1 and the sterilization mechanism 2, which would gradually reduce the sterilization effect. At the same time, the water source can be fully exposed to ultraviolet light to optimize the sterilization effect and ensure drinking water health. The rotation of the baffle plate 10 ensures that the filter plate 7 is in uniform contact with the water source, preventing excessive use of local areas of the filter plate 7, which would cause local filter pore blockage and reduce the inflow velocity. Meanwhile, the friction roller 11 effectively prevents dirt from adhering to and solidifying on the surface of the filter plate 7, accelerating its oxidation rate and shortening the service life.

[0035] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes an anti-impact device 13;

[0036] The anti-impact device 13 includes a transmission rod 131. The left end of the transmission rod 131 is fixedly installed on the right end of the connecting rod 12. The outer wall of the right end of the transmission rod 131 is provided with a non-self-locking reciprocating spiral groove. A spiral blade 132 is installed through and fixedly installed on the outer wall of the transmission rod 131. The spiral blade 132 conveys the water source in a spiral manner to reduce the speed. The spiral blade 132 is located inside the water filtration mechanism 5.

[0037] A sliding ring 133 is slidably installed through the outer wall of the reciprocating spiral groove of the transmission rod 131. A heating mechanism 134 is fixedly installed at equal intervals on the outer wall of the sliding ring 133. A limit ring 135 is fixedly installed at the end of the heating mechanism 134 away from the sliding ring 133. A semi-circular shell 136 is fixedly installed on the right side of the limit ring 135.

[0038] The heating mechanism 134 is used to initially heat the water source to optimize the sterilization effect. The outer wall of the limiting ring 135 is slidably installed on the inner wall of the water storage mechanism 1. The semi-circular shell 136 prevents the water source from flowing back through its own arc surface.

[0039] The spiral contact and conveying of the spiral plate 132 slows down the rapid flow of water, preventing the water from flowing straight in and impacting the U-shaped quartz tube 3, thus reducing the possibility of the U-shaped quartz tube 3 breaking during long-term use. The heating mechanism 134 effectively heats the spirally flowing water, increasing the activity of water molecules within the heated water. Combined with ultraviolet light irradiation, this enhances the sterilization effect of the water and reduces microbial residue. Furthermore, the semi-circular shell 136 guides the water through its outer arc surface, preventing backflow.

[0040] The anti-water accumulation device 14 includes a hollow plate 141. The end of the hollow plate 141 near the heating mechanism 134 is fixedly installed on the outer wall of the limiting ring 135. The end of the hollow plate 141 away from the limiting ring 135 is fixedly installed with a circular ring plate 142. A rotating rod 143 is fixedly installed on the left side of the sterilization mechanism 2. The outer wall of the spiral groove of the rotating rod 143 is penetrated and movably installed inside the circular ring plate 142. Activated carbon plates 144 are fixedly installed at equal intervals on the outer wall of the rotating rod 143.

[0041] The outer wall of the annular plate 142 is slidably installed on the inner wall of the water storage mechanism 1. The rotating rod 143 is located outside the water inlet of the U-shaped quartz tube 3. A non-self-locking spiral groove is opened at one end of the rotating rod 143 near the annular plate 142. The activated carbon plate 144 further optimizes the water quality on the original basis.

[0042] The anti-water accumulation device 14 also includes a fixed arc shell 145. The outer wall of the fixed arc shell 145 is fixedly installed on the inner wall of the water storage mechanism 1. The right side of the fixed arc shell 145 contacts the left edge of the sterilization mechanism 2. Arc-shaped blocks 146 are fixedly installed at equal intervals on the inner wall of the fixed arc shell 145. Arc-shaped filter cotton 147 is fixedly installed on the inner wall of the right end of the fixed arc shell 145. The left end of the arc-shaped filter cotton 147 contacts the right side of the circular plate 142. The outer wall of the arc-shaped filter cotton 147 is fixedly connected to the surface of the arc-shaped block 146. The arc-shaped filter cotton 147 is used to intercept tiny impurities in the water.

[0043] The revolving activated carbon plate 144 continuously makes full contact with the water source, relying on the activated carbon to fully purify the harmful substances contained in the water source, while preventing the residual harmful substances from causing odors to grow inside the water storage device 1 and contaminating the drinking water; through the deformation and reset of the arc-shaped block 146, the water source flowing into the U-shaped quartz tube 3 continues to be squeezed, absorbed and discharged. In this process, tiny impurities or floating objects in the water are absorbed and discharged, improving the purity of the water source on the original basis and preventing the inside of the quartz tube from being contaminated.

[0044] In use, when the connecting rod 12 rotates, it drives the transmission rod 131 to rotate. The transmission rod 131 drives the spiral blade 132 to revolve inside the water filtration mechanism 5. When the spiral blade 132 revolves, it makes spiral contact with the water source entering the water filtration mechanism 5 and transports it. When the transmission rod 131 rotates, it drives the sliding ring 133 to slide towards the U-shaped quartz tube 3 and reset through the non-self-locking reciprocating spiral groove on its outer wall. This process is repeated. At the same time, the sliding ring 133 drives the heating mechanism 134 to move synchronously. During the movement, the heating mechanism 134 changes its own heating orientation to avoid the phenomenon of continuous heating in a single area inside the water storage mechanism 1. During the horizontal movement and reset of the heating mechanism 134, it drives the limiting ring 135 to slide along the inside of the water storage mechanism 1. The limiting ring 135 drives the semi-circular shell 136 to move synchronously. The water source stored in the concave surface of the semi-circular shell 136 is effectively heated by the heating mechanism 134. At the same time, the arc surface of the semi-circular shell 136 intercepts the water source flowing into the water storage mechanism 1.

[0045] According to the above embodiments, the spiral contact and conveying of the spiral plate 132 slows down the rapid flow of water, preventing the water from flowing straight in and impacting the U-shaped quartz tube 3, thus reducing the possibility of the U-shaped quartz tube 3 breaking during long-term use. The heating mechanism 134 effectively heats the spirally flowing water, increasing the activity of water molecules within the heated water. Combined with ultraviolet light irradiation, the sterilization effect of the water is enhanced, reducing microbial residue. Furthermore, the semi-circular shell 136 guides the water through its outer arc surface, preventing backflow.

[0046] Please see Figures 1-8Based on the above embodiments, another embodiment of the present invention further includes a water-prevention device 14;

[0047] In use, when the limiting ring 135 moves horizontally, it drives the hollow plate 141 to move synchronously. The hollow plate 141 pushes the annular plate 142 to move synchronously along the inside of the water storage mechanism 1. When the annular plate 142 moves horizontally, it passes through the outer wall of the rotating rod 143, which has a non-self-locking spiral groove. The limiting force of the spiral groove causes the rotating rod 143 to generate a rotational force. When the rotating rod 143 rotates against the outer wall of the sterilization mechanism 2, it drives the activated carbon plate 144 to revolve. When the activated carbon plate 144 revolves, it enters the U-shaped quartz tube 3. The water source in the part is fully in contact; when the ring plate 142 moves horizontally, it pushes the arc-shaped filter cotton 147, the arc-shaped filter cotton 147 generates a force of motion and is limited by the fixed arc shell 145. At this time, the arc-shaped filter cotton 147 deforms due to the thrust of the ring plate 142. At the same time, the arc-shaped filter cotton 147 is limited by the arc block 146, which causes it to form multiple stress points, so the deformation process is multi-segment deformation. After the water intake work is completed, the electric slide rail 8 extends the operation for a period of time, that is, extends the squeezing movement of the arc-shaped filter cotton 147.

[0048] According to the above embodiment, the revolving activated carbon plate 144 continuously and fully contacts the water source, relying on the activated carbon to fully purify the harmful substances contained in the water source, while preventing the residual harmful substances from causing odors to grow inside the water storage mechanism 1 and contaminating the drinking water; through the deformation and reset of the arc-shaped block 146, the water source flowing into the U-shaped quartz tube 3 continues to be squeezed, absorbed and discharged. In this process, tiny impurities or floating objects in the water are absorbed and the water source is discharged, improving the purity of the water source on the original basis and preventing the inside of the quartz tube from being contaminated.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
