Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to a water channel disinfection device and a control method thereof. Background Art

[0002] During dental treatment, the dental comprehensive treatment chair is the basic equipment for oral diagnosis and treatment. It usually includes an air system, a water system, and an electrical circuit system. In the water system, due to the small diameter of the water supply pipe and the slow flow of liquid, exogenous microorganisms can easily adhere to the surface of objects soaked in water and form a biofilm. If the water in the water system is not effectively disinfected in time, it may become a breeding ground for bacteria and microorganisms, thereby increasing the risk of cross-infection between patients and dentists.

[0003] With the advancement of science and technology, technicians in related fields have also optimized the technical means for disinfecting the water system in dental treatment chairs. In order to make a more accurate comparison, a Chinese patent with publication number CN117923621A discloses a water and gas disinfection device for a dental chair, including a shell, a control device, an ultraviolet disinfection device and an ozone disinfection mechanism, etc. When in use, the ozone disinfection mechanism is used in conjunction with the water inlet and the water outlet to sterilize and disinfect the water used in the dental chair, and the ultraviolet disinfection device is used in conjunction with the air inlet and the air outlet to sterilize and disinfect the air used in the dental chair, which can effectively reduce the possibility of infection problems during oral treatment and improve the user experience.

[0004] However, when using the above-mentioned prior art to disinfect the waterway system, there are still the following problems: The above-mentioned device uses an external device to pass water into the ozone generator, and then electrolyzes the water to produce oxidizing substances to sterilize and disinfect the input water. However, due to the poor stability of ozone itself in water, it will gradually decompose over time and eventually convert into oxygen. In the process of disinfecting and purifying water, ozone will gradually be lost. Therefore, in order to maintain the effective concentration of ozone in the water body and ensure the disinfection and purification effect, ozone needs to be continuously replenished. At the same time, ozone has certain toxicity and is highly corrosive to equipment and materials. Professional operation and safety measures are required when using it. Therefore, the method of using ozone to purify and disinfect water is relatively costly, which reduces the applicability and practicality of the device when used.

[0032] The following is combined with Figure 1 To Attachment Figure 8 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0033] The embodiment of the present application discloses a water channel disinfection device and method, which illustrates that the water channel disinfection device and its control method are mainly used in the process of disinfecting water used in a dental chair, and technically achieve the effect of disinfecting and purifying tap water in the water channel system of a dental chair; in particular, in the process of treating water, the water is sterilized at high temperature and then irradiated with ultraviolet light waves from an exposure lamp to further improve the disinfection and sterilization effect of the water used therein; and the water channel disinfection device also slows down the delivery rate of water into the water storage cylinder through a barrier and a guide plate, to avoid excessive water delivery rate causing large fluctuations in the water in the water storage cylinder, thereby avoiding affecting the efficiency of ultraviolet rays penetrating the water layer to disinfect it.

[0034] Example 1: Reference Figure 1 and Figure 2 As shown, a water disinfection device includes an installation box 1, a water purification cylinder 10, a water storage cylinder 11, a communicating vessel 12, a water inlet pipe 13 and a disinfection unit 2. The interior of the installation box 1 is hollow, and the water purification cylinder 10 and the water storage cylinder 11 with a conical closing structure are limitedly connected in the installation box 1. The water purification cylinder 10 and the water storage cylinder 11 are connected with the communicating vessel 12. The water purification cylinder 10 is arranged at a height higher than the water storage cylinder 11, so that the water after disinfection and purification in the water purification cylinder 10 can be passed into the water storage cylinder 11 through the communicating vessel 12 for storage, which is convenient for the staff to use. The water purification cylinder 10 and the water storage cylinder 11 are both connected with a water inlet pipe 13 that passes through the installation box 1 for introducing water flow, and the disinfection unit 2 for disinfecting and purifying the water stored in the water purification cylinder 10 is connected to the inner wall of the installation box 1.

[0035] When in use, water is introduced into the water purification cylinder 10 through the water inlet pipe 13 by external equipment such as a faucet, and the water in the water purification cylinder 10 is disinfected by the disinfection unit 2. The disinfected water is then introduced into the water storage cylinder 11 through the connecting vessel 12 for use by the staff.

[0036] It should be noted that the water used in the present invention is municipal tap water that has passed primary filtration.

[0037] Reference Figure 2 and Figure 3As shown, a disinfection unit 2 is provided for disinfecting and purifying water stored in a water purification cylinder 10; specifically, the disinfection unit 2 comprises a heating jacket 20, a barrier 21 and a water outlet pipe 22. A limiting sleeve is provided on the outer side surface of the water purification cylinder 10, and an electric heating plate (not shown in the figure) is provided on the heating jacket 20 for heating. The water purification cylinder 10 and the communicating vessel 12 are commonly connected with a barrier 21 for guiding the flow of water therein. The water storage cylinder 11 is connected with a water outlet pipe 22 which passes downward through the installation box 1. The water outlet pipe 22 is connected with a water pump provided in the installation box 1 for pumping out the disinfected and purified water in the water storage cylinder 11 at a certain pressure.

[0038] During use, after water is introduced into the water purification cylinder 10, the barrier 21 is used to prevent the water entering the water purification cylinder 10 from leaking out, and then the electric heating plate (not shown in the figure) is activated to heat the water purification cylinder 10. At this time, the heating jacket 20 is sleeved on the outer side of the water purification cylinder 10 to effectively prevent the excessive dissipation of heat when the electric heating plate (not shown in the figure) generates heat. At the same time, the heat generated by the electric heating plate (not shown in the figure) is concentrated at the water purification cylinder 10, thereby improving the efficiency of the electric heating plate (not shown in the figure) in heating the water in the water purification cylinder 10. After completing the high-temperature sterilization of the water in the water purification cylinder 10, the barrier 21 is released to restrict the water therein, so that the heated water therein enters the water storage cylinder 11 through the communicating vessel 12 for subsequent use by the staff.

[0039] Reference Figure 2 and Figure 3 As shown, a disinfection unit 2 is used to further disinfect and purify the water stored in the water storage cylinder 11; specifically, the disinfection unit 2 also includes a mounting ring 23, a mounting frame 230 and an exposure lamp 231. The mounting ring 23 is concentrically arranged on the outside of the water storage cylinder 11, and the mounting ring 23 is limitedly connected to the mounting box 1 through the mounting frame 230. A plurality of exposure lamps 231 for further disinfecting and purifying the water stored in the water storage cylinder 11 are evenly connected in the circumferential direction of the mounting ring 23.

[0040] When in use, after the water treated with high temperature in the water purification cylinder 10 is passed into the water storage cylinder 11, the exposure lamp 231 is activated, and the ultraviolet light generated by the exposure lamp 231 is irradiated on the water in the water storage cylinder 11 to achieve the effect of further sterilization and disinfection of the water in the water storage cylinder 11.

[0041] It should be noted that ultraviolet disinfection mainly uses ultraviolet rays to penetrate microorganisms in the water, destroying the DNA or RNA of the microorganisms, causing them to lose their ability to reproduce and survive, thereby achieving the purpose of disinfection. Heat sterilization uses high temperatures to destroy the cell structure of microorganisms, causing them to die. High temperatures can also remove certain chemical pollutants in the water, such as chlorides.

[0042] Reference Figure 4 As shown, the communicating vessel 12 includes a funnel 120 sleeved on the lower end of the water purification cylinder 10, the heating jacket 20 is arranged on the upper end of the funnel 120 and fits the outer side of the water purification cylinder 10, and the lower end of the funnel 120 is connected to a connecting pipe 121 arranged in a "U" shape structure, and the two vertical sections of the connecting pipe 121 are respectively connected to the funnel 120 and the water storage cylinder 11.

[0043] When in use, after the water in the water purification cylinder 10 is sterilized at high temperature, it falls into the funnel 120 and the connecting pipe 121, and then enters the water storage cylinder 11 through the connecting pipe 121 to be further disinfected and sterilized.

[0044] Reference Figure 4 As shown, the barrier 21 is used to guide the flow of water between the clean water bucket and the communicating vessel 12; specifically, the barrier 21 includes a connecting slide rod 210, a sliding block 211 and a closed block 212. The clean water barrel 10 is provided with a connecting slide rod 210 that passes through the funnel 120 downward and the connecting tube 121. The upper side of the connecting slide rod 210 is provided with a sliding block 211 that fits with the inner wall of the clean water barrel 10, and the lower side of the connecting slide rod 210 is provided with a closed block 212 that fits with the inner wall of the connecting tube 121.

[0045] During the specific implementation process, when water is injected into the water purification cylinder 10 through the water inlet pipe 13, the water impacts the sliding block 211 downward and the gravity of the water accumulated on the sliding block 211 causes the sliding block 211 to move downward. The sliding block 211 moves downward, driving the connected connecting slide rod 210 and the closed block 212 to move downward, so that as the sliding block 211, the connecting slide rod 210 and the closed block 212 gradually move downward, the sliding block 211 moves downward so that the water inlet pipe 13 is connected to the upper end of the water purification cylinder 10, and at the same time, the closed block 212 moves downward into the connecting pipe 121, so that the channel between the funnel 120 and the connecting pipe 121 is closed. After the water is retained in the water purification cylinder 10, the water in the water purification cylinder 10 is heated by the electric heating plate (not shown in the figure) to achieve the effect of high-temperature sterilization and disinfection of the water therein.

[0046] Further, refer to Figures 4 to 7As shown, a limiting frame 213 for limiting the closing block 212 is sleeved on the connecting slide bar 210, and the limiting frame 213 is inserted on the inner side wall of the connecting through pipe, and a sliding vertical groove for the limiting frame 213 to slide in the vertical direction is symmetrically opened on the inner side wall of the connecting through pipe 121, and a limiting sleeve 214 is sleeved on the lower end of the connecting slide bar 210 after passing through the connecting through pipe 121, and the limiting sleeve 214 is limitedly connected to the installation box 1, and an adjustment spring 215 located in the limiting sleeve 214 is commonly connected between the lower end of the connecting slide bar 210 and the inner bottom wall of the limiting sleeve 214. In the initial state, the adjustment spring 215 is in a normal extension state, the closing block 212 is not inserted on the connecting through pipe 121 to close the connecting through pipe 121, and the sliding block 211 is inserted in the water inlet pipe 13 to close the upper water inlet channel of the water purification cylinder 10.

[0047] During specific use, when water is injected into the water purification cylinder 10 to cause the sliding block 211, the connecting slide rod 210 and the closed block 212 to move downward, the connecting slide rod 210 drives the limit frame 213 to move downward, so that the limit frame 213 slides downward along the sliding vertical groove on the connecting through pipe 121, and at the same time, the connecting slide rod 210 moves downward along the limit sleeve 214 to cause the connected adjusting spring 215 to be compressed. After the water injection is completed, the downward pressure force of the upper end of the sliding block 211 disappears, and the adjusting spring 215 needs to be restored to a normal extended state after being compressed. The adjusting spring 215 extends upward, driving the connecting slide rod 210, the closed block 212 and the sliding block 211 to move upward and reset.

[0048] Furthermore, the extension of the regulating spring 215 will drive the closing block 212 to move upward and reset, so that the closing block 212 releases the sealing of the connecting pipe 121, so that the connecting pipe 121 and the water purification cylinder 10 and the funnel 120 are connected to each other. However, in order to prevent the water in the water purification cylinder 10 from entering the water storage cylinder 11 through the connecting pipe 121 before the water purification cylinder 10 is purified and disinfected, and at the same time, when the water in the water purification cylinder 10 is heated, the inside of the water purification cylinder 10 is always formed into a closed section to ensure the heating and sterilization effect of the water therein, therefore, referring to Figures 4 to 7 As shown, a stop groove 24 is symmetrically provided on the connecting slide rod 210 and the limiting sleeve 214, and a stop block 240 is slidably inserted into the stop groove 24 for limiting the connecting slide rod 210 from continuing to move. The stop block 240 is arranged in a triangular structure, and an extension spring 241 is commonly connected between the stop block 240 and the connecting slide rod 210.

[0049] When in use, by moving the connecting slide bar 210 downward, the connecting slide bar 210 moves and drives all the extension springs 241 and the stop block 240 connected thereto to move downward, and makes the stop block 240 and the extension spring 241 move downward and cross the stop groove 24, the stop block 240 moves downward and slides along the inner wall of the limiting sleeve 214, and makes the extension spring 241 compressed by force until the adjustment spring 215 at the lower end of the connecting slide bar 210 is compressed to a certain position, and then due to the upward restoring elastic force of the adjustment spring 215, the connecting slide bar 210, the stop block 240 and the extension spring 241 are driven to move upward, and when they move to the position of the corresponding stop groove 24, the stop block 240 is inserted into the stop groove 24 on the limiting sleeve 214 under the reset push of the connected extension spring 241, and the stop groove 24 limits the stop block 240 to limit the continued upward movement of the connecting slide bar 210.

[0050] At this time, due to the gravity of the water stored in the water purification cylinder 10 and the restriction of the stop block 240 on the connecting slide rod 210, the adjusting spring 215 is in a state of recovering a certain elasticity upward but not completely recovering the elasticity. As the adjusting spring 215 drives the connecting slide rod 210 to move upward, it also synchronously drives the sliding block 211 and the closing block 212 on the connecting slide rod 210 to move upward. At this time, the sliding block 211 is in a position inserted at the lower end of the water inlet pipe 13 to close the upper side of the water purification cylinder 10, and the closing block 212 is located at the connection between the funnel 120 and the connecting pipe 121 to close the lower side of the water purification cylinder 10, so that a closed space is formed in the water purification cylinder 10 to prevent the water therein from being discharged outward before the disinfection is completed.

[0051] Reference Figures 4 to 7 As shown, in order to discharge the water after heating and disinfection in the water purification cylinder 10, a driving motor 25 is connected to the lower end of the limiting sleeve 214, and the driving motor 25 is installed on the inner bottom wall of the installation box 1 through the motor seat. A driving gear 250 is sleeved on the limiting sleeve 214, and the outer side surface of the driving gear 250 meshes with the driven gear 251. A rotating wheel rod 252 is penetrated in the middle of the driven gear 251. The rotating wheel rod 252 is rotatably sleeved with a mounting side plate 253 connected to the driving motor 25, and the upper end of the rotating wheel rod 252 is connected to an adjusting screw 2 54, a driven sleeve 255 is threadedly sleeved on the adjusting screw 254, and the driven sleeve 255 is also rotatably sleeved on the connecting slide 210, and at the same time, the connecting slide 210 and the limiting sleeve 214 are arranged in a spline matching manner, that is, the outer side surface of the connecting slide 210 is symmetrically connected to the limiting slide, and a limiting slide groove adapted to the limiting slide and for the limiting slide to slide in the vertical direction is opened in the limiting sleeve 214, and the limiting slide groove is communicated with the stop groove 24, and at this time, the limiting frame 213 and the connecting slide 210 are arranged to be rotatably connected.

[0052] When in use, the output shaft of the driving motor 25 is rotated to drive the limiting sleeve 214 and the driving gear 250 to rotate, the driving gear 250 rotates to drive the meshing driven gear 251 to rotate, the driven gear 251 rotates to drive the rotating wheel rod 252 and the adjusting screw 254 to rotate, and the threaded section 2541 on the adjusting screw 254 drives the driven sleeve plate 255 to move up, the driven sleeve plate 255 moves up to drive the connecting slide bar 210, the limiting slide bar, the stop block 240 and the extension spring 241 to move up, and the extension spring 241 is compressed again, and the stop block 240 passes over the stop block 240. After the corresponding stop groove 24, since the adjusting spring 215 has not been fully reset, under the upward drive of the adjusting spring 215, the connecting slide rod 210 drives the sliding block 211 and the closing block 212 to fully reset upward, so that the adjusting spring 215 extends to a normal state. At this time, the sliding block 211 continues to move up along the water inlet pipe 13 and closes it, while the closing block 212 moves up to the funnel 120, and releases the closing state of the connecting through pipe 121, so that the disinfected water in the water purification cylinder 10 is discharged. At this time, the limit frame 213 is driven by the connecting slide rod 210 to move up to the uppermost end of the sliding vertical groove.

[0053] Furthermore, the adjusting screw 254 is configured with a non-threaded section 2540 and a threaded section 2541 at the top and bottom. After the adjusting screw 254 is driven to rotate, the driven sleeve 255 is disengaged from the threaded section 2541 when it moves from the rotating wheel rod 252 to contact with the threaded section 2541 and when it moves from the threaded section 2541 to the non-threaded section 2540, and vice versa, so that when the adjusting screw 254 is driven to rotate, the driven sleeve 255 will not interfere with the normal rotation of the adjusting screw 254.

[0054] Reference Figure 4 As shown, in order to improve the heating efficiency of the water in the water purification cylinder 10, a plurality of stirring blades 26 are evenly arranged on the connecting slide bar 210 in the circumferential direction, which are located in the water purification cylinder 10 and are used to stir the water in the water purification cylinder 10. When in use, after the connecting slide bar 210 is driven to rotate by the driving motor 25, the connecting slide bar 210 rotates to drive all the stirring blades 26 connected to the outside thereof to rotate in the water purification cylinder 10. After the stirring blades 26 rotate, the water in the water purification cylinder 10 is driven to shift, so that the water in the water purification cylinder 10 remains in a flowing state when being heated and is always heated evenly, avoiding the phenomenon of inconsistent heating temperatures in various areas of the water purification cylinder 10 and large temperature differences, thereby avoiding the problem of increased loss due to the prolonged operation time of the electric heating plate (not shown in the figure).

[0055] As an optional embodiment, when injecting the municipal tap water to be treated into the water purification cartridge 10, a certain amount of chemical disinfectant can also be added to the water purification cartridge 10 to improve the effect of disinfecting and purifying the water in the water purification cartridge 10. At this time, by driving the stirring blade 26 to stir the water in the water purification cartridge 10, the chemical disinfectant and water can be quickly mixed, thereby improving the efficiency of disinfecting and purifying the water by the chemical disinfectant.

[0056] Reference Figure 4 As shown, a filter box 27 is connected to the upper limit of the inner wall of the connecting tube 121. The hollow interior of the filter box 27 contains a number of activated carbons for further adsorbing and purifying the discharged water. The filter box 27 is evenly provided with a number of through holes for communicating with the interior of the connecting tube 121 for water to pass through. When in use, after the water in the water purification cylinder 10 is heated and sterilized, the water in the water purification cylinder 10 is further adsorbed and sterilized by the activated carbons disposed in the filter box 27 when it is discharged through the funnel 120 and the connecting tube 121, thereby improving the sterilization and purification effect of the water therein.

[0057] Furthermore, a connecting slide rod 210 is also provided in the water storage cylinder 11, and the connecting slide rod 210 slides downward to pass through the connecting pipe 121. A sliding block 211, a closing block 212 and a limit frame 213 are sequentially connected to the outer side of the connecting slide rod 210 from top to bottom. A sliding vertical groove is also opened on the vertical section of the connecting pipe 121 connected to the water storage cylinder 11, and the limit frame 213 is slidably inserted in the limit vertical groove.

[0058] During use, the filter box 27 is used to disinfect the water from the water purification cylinder 10 while slowing down the rate at which the water therein flows into the water storage cylinder 11, so as to prevent the water from flowing into the water storage cylinder 11 too quickly, causing large fluctuations in the liquid level in the water storage cylinder 11, thereby affecting the penetration efficiency of the exposure lamp 231 penetrating the water layer, thereby affecting the purification and disinfection effect thereof. After the connecting pipe 121 is filled with water, as the water in the connecting pipe 121 increases, the buoyancy of the water drives the limit frame 213 and the closing block 212 on one side of the water storage cylinder 11 to move upward, so that the connecting pipe 121 is connected to the water storage cylinder 11. At the same time, the upward movement of the limit frame 213 and the closing block 212 also drives the connected connecting slide rod 210 and the sliding block 211 to move upward, so that the sliding block 211 closes the water inlet pipe 13 on the water storage cylinder 11, so as to prevent the water after heating and disinfection from contacting the outside world again, causing repeated contamination.

[0059] Example 2: Reference Figure 4 and Figure 8As shown, on the basis of the first embodiment, since the method of high-temperature sterilization of the water in the water purification cylinder 10 by heating usually requires a certain amount of time to make the water temperature rise evenly, and the water temperature needs to be maintained for a period of time after rising to achieve the effect of completely disinfecting and purifying the water, according to the needs during use, if the disinfected and purified water is needed in a short time, and the disinfection requirements are not too high, such as rinsing the instrument or the patient's mouth, the water to be treated can be introduced into the water storage cylinder 11 through the water inlet pipe 13 connected to the water storage cylinder 11. At this time, the water therein can be directly irradiated by a number of exposure lamps 231 evenly arranged on the outside of the water storage cylinder 11 to achieve the effect of rapid disinfection and purification of the water therein. The water disinfected by the exposure lamp 231 meets the water use standards of the dental chair and will not cause the water temperature to be too high, thereby causing thermal damage to the patient.

[0060] Based on this, a guide plate 3 located between the sliding block 211 and the closed block 212 is also provided on the connecting slide rod 210 located in the water storage cylinder 11. The guide plate 3 is arranged in an arc-shaped structure and is close to the sliding block 211 on the upper side. The size of the guide plate 3 is larger than the size of the sliding block 211 and the closed block 212. During use, when water is poured into the water storage cylinder 11, the connecting slide rod 210, the sliding block 211 and the closing block 212 located in the water storage cylinder 11 are driven to move downward, so that the water storage cylinder 11 is connected with the water inlet pipe 13 at its upper end. After the water enters the water storage cylinder 11, it first falls on the sliding block 211 and then splashes around along the end surface of the sliding block 211 to the inner wall of the water storage cylinder 11, then drops on the guide plate 3, and then falls into the water storage cylinder 11 along the curved surface of the guide plate 3. The multi-stage barrier of the water injected into the water storage cylinder 11 by the sliding block 211 and the guide plate 3 in the water storage cylinder 11 effectively avoids the problem that the water in the water storage cylinder 11 fluctuates due to the large height difference when the water is injected, thereby affecting the efficiency of the ultraviolet rays generated by the exposure lamp 231 passing through the water layer.

[0061] After the water level in the water storage cylinder 11 moves up and exceeds the height of the guide plate 3, the guide plate 3 floats in the water to be flush with the liquid surface. When the guide plate 3 moves up, it drives the connected connecting slide rod 210, the closing block 212 and the sliding block 211 to move up. When the sliding block 211 moves up, it is reinserted into the water inlet pipe 13 connected to the water storage cylinder 11 to close it, so as to avoid the problem of continuing to inject water into the water storage cylinder 11.

[0062] Reference Figure 8 As shown, as the position of the closed block 212 between the water storage cylinder 11 and the connecting pipe 121 moves upward, the lower end of the water storage cylinder 11 will be gradually opened. In order to prevent the water therein from being discharged before the disinfection is completed, a linkage strip plate 30 connected to the driven sleeve plate 255 is sleeved on the connecting slide rod 210 inserted in the water storage cylinder 11.

[0063] During use, when water is injected into the water storage cylinder 11, the sliding block 211 in the water storage cylinder 11 is driven downward to move downward, so that the upper end of the water storage cylinder 11 is opened, and the sliding block 211 moves downward, driving the connected connecting slide rod 210 and the closed block 212 downward. At the same time, the connecting slide rod 210 in the water storage cylinder 11 moves downward, driving the linkage strip plate 30 and the driven sleeve plate 255 downward, and the driven sleeve plate 255 moves downward, driving the connecting slide rod 210 in the water purification cylinder 10 and the stop block 240 on the connecting slide rod 210 downward, so that the stop block 240 is driven by the connected extension spring 241 to be inserted into the stop groove 24, thereby achieving the effect of limiting the position of the two connecting slide rods 210. At this time, the water purification cylinder 10 and the water storage cylinder 11 are both formed into closed chambers.

[0064] After completing the disinfection and purification of the water in the water storage cylinder 11, the adjusting screw 254 is driven to rotate by the driving motor 25, so that the stop block 240 is disengaged from the stop groove 24, and driven by the upward elastic restoring force of the adjusting spring 215, the connecting slide rod 210 located in the water purification cylinder 10 is driven to move upward, and at the same time, the driven sleeve plate 255, the linkage strip plate 30 and the other connecting slide rod 210 are driven upward by the connecting slide rod 210. After the two connecting slide rods 210 move up, they drive the connected closed block 212 to move upward, thereby achieving the effect of releasing the seal on the lower ends of the water purification cylinder 10 and the water storage cylinder 11.

[0065] Further, refer to Figure 8 As shown, a piston block 31 is inserted into the water outlet pipe 22 for closing the water inlet of the water outlet pipe 22. The piston block 31 is connected to the closing block 212 in the water storage cylinder 11 through a bent connecting rod 32, and the height of the piston block 31 is set higher than the height of the closing block 212.

[0066] During use, when the closing block 212 is driven to move upward, the closing block 212 drives the connected bent connecting rod 32 and the piston block 31 to move upward. Since the height of the piston block 31 is higher than the setting of the closing block 212, the driving motor 25 is stopped from rotating. The driven sleeve 255 is on the upper side of the upper threaded section 2541 of the adjusting screw 254, but has not yet disengaged. The threaded section 2541 restricts the driven sleeve 255 to limit the continued upward movement of the two connecting slide bars 210, so that only the channel at the water outlet pipe 22 is opened. At this time, the water in the water storage cylinder 11 is transported outward by the water pump for use by the staff.

[0067] In another embodiment, by making the height of the piston block 31 lower than the height of the closing block 212, when the connecting slide rod 210 is driven to slide upward, the closing block 212 close to the side of the water storage cylinder 11 first opens the channel at the connecting pipe 121, and then after completing the disinfection and purification of the water storage cylinder 11, the connecting slide rod 210 is driven to drive the closing block 212, the bent connecting rod 32 and the piston block 31 to move further upward to open the water outlet pipe 22. At this time, the water in the water storage cylinder 11 is transported outward by the water pump for use by the staff.

[0068] In addition, the present invention also provides a waterway disinfection device control method, comprising the following steps: S1. Water injection preparation. After the water to be treated is injected into the water purification cylinder 10, the water purification cylinder 10 is sealed by the barrier 21 to form a closed space in the water purification cylinder 10. Then, the water purification cylinder 10 is heated by the heating jacket 20. After maintaining the temperature for a period of time, the high-temperature sterilization and disinfection effect of the water purification cylinder 10 is completed.

[0069] S2, secondary disinfection, after the water in the water purification cylinder 10 is introduced into the water storage cylinder 11, the water therein is irradiated by the exposure lamp 231 outside the water storage cylinder 11, and the ultraviolet light emitted by the exposure lamp 231 achieves the effect of secondary disinfection and purification of the water therein.

[0070] S3. After the disinfection is completed, the water in the water storage cylinder 11 is extracted for use by the staff.
