Description

Technical Field

[0001] The present invention relates to the technical field of drinking water sterilization, and specifically to an in-line UV ultraviolet sterilization device for a drinking water storage tank. Background Art

[0002] With the development of social economy, people pay more and more attention to the health of themselves and their families. In our daily life, the health of drinking water has an important impact on people's physical health. Therefore, the sterilization standards and requirements for drinking water are constantly improving.

[0003] A patent with the publication number CN215479881U discloses an in-line UV ultraviolet sterilization device for drinking water, belonging to the field of drinking water sterilization. It includes a storage tank, a sterilization component, and a water circulation component. The sterilization component is detachably fixed at one end opening of the storage tank, and a water inlet communicating with the storage tank is provided on one side surface of the sterilization component. The water circulation component is detachably fixed at the other end opening of the storage tank, and a water outlet communicating with the storage tank is provided on one side surface of the water circulation component. The sterilization component includes a radiator detachably fixed to one end opening of the storage tank. The water inlet is provided at the center of one side surface of the radiator, and an annular cavity is formed around the water inlet inside the radiator. A driving power source is fixedly connected inside the annular cavity. A plurality of UVC-LED light sources are fixed along the water inlet on the side surface of the radiator close to the storage tank. By setting the water circulation component, the water flow mode can be improved to achieve the effect of long-term water flow retention and cyclic sterilization.

[0004] However, this device still has deficiencies: this device realizes cyclic sterilization by improving the water flow mode. However, when the water flow enters the storage tank, it is easy to carry dirt such as sediment due to poor filtration, and it is difficult to effectively remove it during the subsequent ultraviolet sterilization process. Moreover, dirt such as sediment accumulates in the storage tank for a long time, which is likely to exacerbate the oxidation and pollution of the storage tank and the sterilization mechanism, and easily leads to a gradual reduction in the sterilization effect. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an in-line UV ultraviolet sterilization device for a drinking water storage tank, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: An over-flow type UV ultraviolet sterilization device for a drinking water storage tank, comprising a water storage mechanism, a sterilization mechanism is arranged on the right side of the water storage mechanism, a U-shaped quartz tube is arranged on the left side of the sterilization mechanism, a straight quartz tube is arranged inside the U-shaped quartz tube, a water filtration mechanism is arranged on the left side of the water storage mechanism, an anti-shock device for protecting the sterilization mechanism is arranged on the right side of the water filtration mechanism, and an anti-ponding device for reducing water source residue is arranged on the right side of the anti-shock device. A number of ultraviolet components are fixedly installed at equal intervals inside the right end of the water filtration mechanism, a filter plate is fixedly installed inside the water filtration mechanism, an electric slide rail is fixedly installed on the inner wall of the left end of the water filtration mechanism, a number of sliding blocks are fixedly installed at equal intervals inside the electric slide rail, a spoiler is fixedly installed at one end of the sliding block away from the electric slide rail, a friction roller is fixedly installed inside the chute of the spoiler, and a connecting rod is fixedly installed at one end of the spoiler away from the electric slide rail.

[0007] According to the above technical solutions, the sterilization mechanism sterilizes the drinking water to ensure drinking water safety. The U-shaped quartz tube is located inside the water storage mechanism, the U-shaped quartz tube maps ultraviolet rays, water inlets are symmetrically arranged on the outer wall of the U-shaped quartz tube, and 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 solutions, the outer wall of the left end of the water filtration mechanism is of a spiral design, and the water filtration mechanism is used for connecting and transporting water sources. The ultraviolet components cooperate with the sterilization mechanism to improve the sterilization effect on drinking water. The electric slide rail is located on the left side of the filter plate. The spoiler realizes a revolution movement through the power source provided by the electric slide rail. A chute is arranged on the side of the spoiler close to 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 movably penetrates inside the filter plate. The water filtration mechanism is screwed into the water source installation place through a spiral groove. When the water source enters the water storage mechanism through the water filtration mechanism, it will contact the filter plate. The filter plate blocks dirt such as sediment in the water to prevent the dirt from entering the inside of the water storage mechanism synchronously. Subsequently, the water source is sterilized by the UV ultraviolet light irradiated by the ultraviolet components. After the water source enters the inside of the water storage mechanism, it is shunted and circulated through the U-shaped cotton of the U-shaped quartz tube to extend the residence time of the water source inside the water storage mechanism. At the same time, the U-shaped quartz tube and the straight quartz tube map the ultraviolet light. Then the water source enters through the water inlet of the U-shaped quartz tube and is discharged through the straight quartz tube and the sterilization mechanism; before the water inlet starts, the electric slide rail is started. The electric slide rail drives the sliding block to revolve inside itself. When the sliding block revolves, it drives the spoiler to revolve. When the spoiler revolves, it differentiates the water source to avoid the water source flowing through the surface of the filter plate continuously and within a single range. When the spoiler revolves, it drives the friction roller to revolve and rub along the surface of the filter plate. At the same time, the spoiler drives the connecting rod to rotate. During this process, the friction roller rotates by itself inside the chute of the spoiler by relying on the friction force. During the revolution and rotation of the friction roller, it continuously wipes the surface of the filter plate to prevent dirt in the water from adhering and solidifying on the surface of the filter plate for a long time.

[0009] According to the above technical solution, the impact-proof device includes a transmission rod. The left end of the transmission rod is fixedly installed at the right end of the connecting rod. A non-self-locking reciprocating spiral groove is formed on the outer wall of the right end of the transmission rod. A spiral blade is penetrated and fixedly installed on the outer wall of the transmission rod. The spiral blade spirally conveys water to reduce the speed. The spiral blade is located inside the water filtering 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 filtering mechanism. When the spiral blade revolves, it makes spiral contact with the water source entering the water filtering mechanism and conveys it.

[0010] According to the above technical solution, a sliding ring is penetrated and slidably installed on the outer wall of the reciprocating spiral groove of the transmission rod. Heating mechanisms are fixedly installed on the outer wall of the sliding ring at equal intervals. A limiting ring is fixedly installed at one end of the heating mechanism away from the sliding ring. A semi-circular shell is fixedly installed on the right side of the limiting 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 at the inner wall of the water storage mechanism. The semi-circular shell blocks the backflow of water through its arc surface. When the transmission rod rotates, the sliding ring is driven to slide towards and reset towards the direction close to the U-shaped quartz tube through the non-self-locking reciprocating spiral groove on its outer wall. This process repeats. At the same time, the sliding ring drives the heating mechanism to move synchronously. During the movement of the heating mechanism, its heating orientation changes, avoiding continuous heating in a single range inside the water storage mechanism. During the horizontal movement and reset of the heating mechanism, the limiting ring is driven to slide along the inner wall of the water storage mechanism, and the limiting ring drives the semi-circular shell to move synchronously. The water stored in the concave surface of the semi-circular shell is effectively heated by the heating mechanism, and at the same time, the arc surface of the semi-circular shell intercepts the water flowing into the water storage mechanism.

[0012] According to the above technical solution, the water accumulation prevention device includes a hollow plate. One end of the hollow plate close to the heating mechanism is fixedly installed on the outer wall of the limiting ring. A circular ring plate is fixedly installed at the 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 on the outer wall of the rotating rod at equal intervals.

[0013] According to the above technical solution, the outer wall of the circular ring plate is slidably installed on the inner wall of the water storage mechanism. The rotating rod is located around the water inlet of the U-shaped quartz tube. A non-self-locking spiral groove is provided at one end of the rotating rod close to the circular ring 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 circular ring plate to move synchronously along the inside of the water storage mechanism. When the circular ring plate moves horizontally, it will pass through the outer wall of the rotating rod where the non-self-locking spiral groove is provided. The spiral groove limits the rotating rod to generate a self-rotating force. When the rotating rod rotates around the outer wall of the sterilization mechanism, the rotating rod drives the activated carbon plate to revolve. When the activated carbon plate revolves, it comes into full contact with the water source entering the U-shaped quartz tube.

[0014] According to the above technical solution, the water accumulation prevention device further 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 is in contact with the left edge of the sterilization mechanism. Arc-shaped blocks are fixedly installed on the inner wall of the fixed arc shell at equal intervals. An arc-shaped filter cotton is fixedly installed on the inner wall at the right end of the fixed arc shell. The left end of the arc-shaped filter cotton is in contact with 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 functions 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 moving force and is limited by the fixed arc shell. At this time, the arc-shaped filter cotton deforms under the thrust of the circular ring plate. At the same time, the arc-shaped filter cotton is limited by the arc-shaped block, prompting it to form multiple force application points, so that the deformation process is multiple-segment deformation. And after the water inlet operation is completed, the electric slide rail runs for an extended period of time, that is, the extrusion movement of the arc-shaped filter cotton is extended.

[0015] The present invention provides an over-flow type UV ultraviolet sterilization device for a drinking water storage tank. It has the following beneficial effects: (1) Through the cooperation of the U-shaped quartz tube, the straight quartz tube, the water filtration mechanism, the ultraviolet component, the filter plate, the electric slide rail, the sliding block, the flow disturbing plate, the friction roller and the connecting rod, the present invention effectively intercepts dirt such as sediment through the filter plate, preventing it from settling in the water storage mechanism for a long time, avoiding pollution to the water storage mechanism and the sterilization mechanism, resulting in a gradual reduction in the sterilization effect. At the same time, the water source can be fully exposed to ultraviolet light irradiation to optimize the sterilization effect and ensure drinking water health; through the revolution of the flow disturbing plate, the entire filter plate is evenly in contact with the water source, preventing local overuse of the filter plate, causing blockage of its local filter holes and reducing the inflow rate. 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 while shortening the service life.

[0016] (2) Through the setting of the impact prevention device, the present invention cooperates with a connecting rod, a transmission rod, a spiral sheet, a sliding ring, a heating mechanism, a limiting ring and a semi-circular shell. Through the spiral contact and transportation of the spiral sheet, the rapid water source is decelerated to avoid the direct pouring and impact of the water source on the U-shaped quartz tube, reducing the possibility of the U-shaped quartz tube cracking during long-term use. The heating mechanism effectively heats the spiral flowing water source, and the heated water source accelerates the activity of water molecules inside itself. Then, combined with ultraviolet light irradiation, the bactericidal effect of the water source is improved on the original basis, reducing microbial residues. Moreover, the semi-circular shell guides the water source through the outer wall arc surface to avoid the phenomenon of water source backflow.

[0017] (3) Through the setting of the water accumulation prevention device, the present invention cooperates with a limiting ring, a hollow plate, a circular ring plate, a rotating rod, an activated carbon plate, a fixed arc shell, an arc-shaped block and arc-shaped filter cotton. Through the revolution of the activated carbon plate, it 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 growth of peculiar smell in the water storage mechanism due to the residue of harmful substances and the infection of drinking water. Through the deformation and reset of the arc-shaped block, it continues to squeeze, absorb and discharge the water source flowing into the U-shaped quartz tube. During this process, tiny impurities or floating substances 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 internal pollution of the quartz tube.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Please refer to Figures 1-8 , an embodiment of the present invention is: an over-flow type UV ultraviolet sterilization device for a drinking water storage tank, including a water storage mechanism 1, a sterilization mechanism 2 is arranged on the right side of the water storage mechanism 1, a U-shaped quartz tube 3 is arranged on the left side of the sterilization mechanism 2, a straight quartz tube 4 is arranged inside the U-shaped quartz tube 3, a water filtration mechanism 5 is arranged on the left side of the water storage mechanism 1, an impact protection device 13 for protecting the sterilization mechanism 2 is arranged on the right side of the water filtration mechanism 5, a water accumulation prevention device 14 for reducing water source residue is arranged on the right side of the impact protection 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 turbulence plate 10 is fixedly installed at one end of the sliding block 9 away from the electric slide rail 8, a friction roller 11 is fixedly installed inside the chute of the turbulence plate 10, and a link 12 is fixedly installed at one end of the turbulence plate 10 away from the electric slide rail 8.

[0022] The sterilization mechanism 2 sterilizes the 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 maps ultraviolet rays. Water inlets are symmetrically opened on the outer wall of the U-shaped quartz tube 3. The right end of the straight quartz tube 4 is fixedly installed on the left side of the sterilization mechanism 2.

[0023] The outer wall of the left end of the water filtration mechanism 5 is of a spiral design, and the water filtration mechanism 5 is used for connecting and transporting water sources. The ultraviolet components 6 and the sterilization mechanism 2 cooperate with each other 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 turbulence plate 10 realizes a revolution movement through the power source provided by the electric slide rail 8. A chute is opened on the side of the turbulence plate 10 close to 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 link 12 movably penetrates inside the filter plate 7.

[0024] The filter plate 7 effectively intercepts dirt such as sediment, preventing it from settling in the water storage mechanism 1 for a long time, avoiding pollution to the water storage mechanism 1 and the sterilization mechanism 2, which may lead to a gradual decrease in the sterilization effect. At the same time, the water source can fully contact the ultraviolet light irradiation to optimize the sterilization effect and ensure drinking water health. Through the revolution of the flow deflector 10, the whole filter plate 7 can evenly contact the water source, preventing the local area of the filter plate 7 from being overused, causing blockage of its local filter holes and reducing the inflow rate. At the same time, the friction roller 11 effectively prevents dirt from adhering and solidifying on the surface of the filter plate 7, accelerating its oxidation rate while shortening the service life.

[0025] During use, the water filtering mechanism 5 is screwed into the water source installation location through the spiral groove. When the water source enters the water storage mechanism 1 through the water filtering mechanism 5, it will contact the filter plate 7. The filter plate 7 blocks dirt such as sediment in the water, preventing the dirt from entering the water storage mechanism 1 simultaneously. Subsequently, the UV ultraviolet light irradiated by the ultraviolet component 6 is used to sterilize the water source. After the water source enters the water storage mechanism 1, it is shunted and circulated through the U-shaped cotton of the U-shaped quartz tube 3, extending the residence time of the water source in the water storage mechanism 1. At the same time, the U-shaped quartz tube 3 and the straight quartz tube 4 map the ultraviolet light. Then the water source enters through the water inlet of the U-shaped quartz tube 3 and is discharged through the straight quartz tube 4 and the sterilization mechanism 2. Before the water inlet starts, the electric slide rail 8 is started. The electric slide rail 8 drives the sliding block 9 to revolve within itself. When the sliding block 9 revolves, it drives the flow deflector 10 to revolve. When the flow deflector 10 revolves, it differentiates the water source, preventing the water source from continuously flowing through the surface of the filter plate 7 in a single range. When the flow deflector 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 flow deflector 10 drives the connecting rod 12 to rotate. During this process, the friction roller 11 rotates on its own within the chute of the flow deflector 10 by relying on the friction force. During the revolution and rotation of the friction roller 11, it continuously wipes the surface of the filter plate 7, preventing dirt in the water from adhering and solidifying on the surface of the filter plate 7 for a long time.

[0026] According to the above embodiments, the filter plate 7 effectively intercepts dirt such as sediment, preventing it from settling in the water storage mechanism 1 for a long time, avoiding pollution to the water storage mechanism 1 and the sterilization mechanism 2, which may lead to a gradual decrease in the sterilization effect. At the same time, the water source can fully contact the ultraviolet light irradiation to optimize the sterilization effect and ensure drinking water health. Through the revolution of the flow deflector 10, the whole filter plate 7 can evenly contact the water source, preventing the local area of the filter plate 7 from being overused, causing blockage of its local filter holes and reducing the inflow rate. At the same time, the friction roller 11 effectively prevents dirt from adhering and solidifying on the surface of the filter plate 7, accelerating its oxidation rate while shortening the service life.

[0027] Please refer to Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, an anti-shock device 13 is further included; The impact protection device 13 includes a transmission rod 131. The left end of the transmission rod 131 is fixedly installed at the right end of the connecting rod 12. A non-self-locking reciprocating spiral groove is provided on the outer wall of the right end of the transmission rod 131. A spiral blade 132 is penetrated and fixedly installed on the outer wall of the transmission rod 131. The spiral blade 132 spirally conveys the water source to reduce the speed, and the spiral blade 132 is located inside the water filtering mechanism 5.

[0028] A sliding ring 133 is penetrated and slidably installed on the outer wall of the reciprocating spiral groove of the transmission rod 131. Heating mechanisms 134 are equidistantly and fixedly installed on the outer wall of the sliding ring 133. A limiting ring 135 is fixedly installed at one 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 limiting ring 135.

[0029] 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 at the inner wall of the water storage mechanism 1. The semi-circular shell 136 blocks the backflow of the water source through its arc surface.

[0030] Through the spiral contact and conveyance of the spiral blade 132, the rapid water source is decelerated to prevent the water source from directly pouring in and impacting the U-shaped quartz tube 3, reducing the possibility of the U-shaped quartz tube 3 cracking during long-term use. The heating mechanism 134 effectively heats the spirally flowing water source. The heated water source accelerates the activity of its internal water molecules. Coupled with ultraviolet light irradiation, the sterilization effect of the water source is improved on the original basis, reducing microbial residues. And the semi-circular shell 136 guides the water source through its outer wall arc surface to prevent the backflow of the water source.

[0031] The water accumulation prevention device 14 includes a hollow plate 141. One end of the hollow plate 141 close to the heating mechanism 134 is fixedly installed on the outer wall of the limiting ring 135. A circular ring plate 142 is fixedly installed at the end of the hollow plate 141 away from the limiting ring 135. 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 equidistantly and fixedly installed on the outer wall of the rotating rod 143.

[0032] The outer wall of the circular ring plate 142 is slidably installed on the inner wall of the water storage mechanism 1. The rotating rod 143 is located around the water inlet of the U-shaped quartz tube 3. A non-self-locking spiral groove is provided at one end of the rotating rod 143 close to the circular ring plate 142. The activated carbon plates 144 further optimize the quality of the water source on the original basis.

[0033] The water accumulation prevention device 14 further includes a fixed arc shell 145. The outer wall of the fixed arc shell 145 is fixedly installed at the inner wall of the water storage mechanism 1. The right side of the fixed arc shell 145 is in contact with the left edge of the sterilization mechanism 2. Arc-shaped blocks 146 are fixedly installed equidistantly on the inner wall of the fixed arc shell 145. An arc-shaped filter cotton 147 is fixedly installed on the inner wall at the right end of the fixed arc shell 145. The left end of the arc-shaped filter cotton 147 is in contact with the right side of the circular ring 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 functions to intercept tiny impurities in the water.

[0034] Through the revolving activated carbon plate 144, it 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 generation of peculiar smells in the water storage mechanism 1 caused by the residue of harmful substances and infecting the drinking water; through the deformation and reset of the arc-shaped block 146, it continues to squeeze, absorb and discharge the water source flowing into the U-shaped quartz tube 3. During this process, it absorbs tiny impurities or floating substances in the water and discharges the water source, improving the purity of the water source on the original basis and avoiding pollution inside the quartz tube.

[0035] During 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 filtering mechanism 5. When the spiral blade 132 revolves, it makes spiral contact with the water source entering the water filtering mechanism 5 and conveys it; when the transmission rod 131 rotates on its own axis, through the non-self-locking reciprocating spiral groove on its outer wall, it drives the sliding ring 133 to slide towards the direction close to the U-shaped quartz tube 3 and reset. This repeats continuously. At the same time, the sliding ring 133 drives the heating mechanism 134 to move synchronously. During the movement of the heating mechanism 134, it changes its own heating orientation to avoid the phenomenon of continuous heating in a single range 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 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.

[0036] According to the above embodiments, through the spiral contact and conveyance of the spiral blade 132, the rapid water source is decelerated to avoid the direct pouring of the water source and impact on the U-shaped quartz tube 3, reducing the possibility of the U-shaped quartz tube 3 cracking during long-term use; through the effective heating treatment of the spiral flowing water source by the heating mechanism 134, the heated water source accelerates the activity of water molecules inside itself, and then cooperates with ultraviolet light irradiation to improve the sterilization effect of the water source on the original basis, reduce the residue of microorganisms, and the semi-circular shell 136 guides the water source through the outer wall arc surface to avoid the phenomenon of water source backflow.

[0037] Please refer to Figures 1-8, on the basis of the above embodiments, another embodiment of the present invention further includes a water accumulation prevention device 14; During use, when the limit ring 135 moves horizontally, it drives the hollow plate 141 to move synchronously. The hollow plate 141 pushes the circular ring plate 142 to move synchronously along the inside of the water storage mechanism 1. When the circular ring plate 142 moves horizontally, it will pass through the outer wall of the rotating rod 143 provided with a non-self-locking spiral groove. The limit of the spiral groove causes the rotating rod 143 to generate a force for self-rotation. When the rotating rod 143 rotates around the outer wall of the sterilization mechanism 2, the rotating rod 143 drives the activated carbon plate 144 to revolve. When the activated carbon plate 144 revolves, it is in full contact with the water source entering the U-shaped quartz tube 3; when the circular ring plate 142 moves horizontally, it pushes the arc-shaped filter cotton 147. The arc-shaped filter cotton 147 generates a force for movement and is limited by the fixed arc shell 145. At this time, the arc-shaped filter cotton 147 deforms under the thrust of the circular ring plate 142. At the same time, the arc-shaped filter cotton 147 is limited by the arc-shaped block 146, prompting it to form multiple force application points. Therefore, during the deformation process, it undergoes multi-segment deformation. And after the water inlet operation is completed, the electric slide rail 8 runs for an extended period of time, that is, the extrusion movement of the arc-shaped filter cotton 147 is extended.

[0038] According to the above embodiments, through the revolving activated carbon plate 144, it 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. At the same time, it avoids the generation of peculiar smells in the water storage mechanism 1 caused by the residue of harmful substances and the infection of drinking water; through the deformation and reset of the arc-shaped block 146, it continues to squeeze, absorb and discharge the water source flowing into the U-shaped quartz tube 3. During this process, it absorbs the tiny impurities or floating substances in the water and discharges the water source, improving the purity of the water source on the original basis and avoiding pollution inside the quartz tube.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
