[0013] As a further aspect of the present invention: the water purification antibacterial and antiviral filtration device also includes an input pipe, the output end of which is connected to the top of the inlet pipe for inputting the water to be treated into the inlet pipe.

[0014] As a further embodiment of the present invention: the slag collection tank is formed by an installation ring, an L-shaped mating ring and a side wall of the filtration and sterilization chamber, wherein the installation ring is fixedly installed below the filter screen, the L-shaped mating ring is fixedly installed on the side wall of the filtration and sterilization chamber, the L-shaped mating ring includes a side ring and a bottom ring fixedly installed on the side ring, the outer side of the bottom ring is fixedly installed on the side wall of the filtration and sterilization chamber, the inner side of the bottom ring is fixedly installed on the bottom of the side ring, and the outer side of the side ring is attached to the outer side of the installation ring.

When the water reaches a certain level, the filter screen will descend. After descending to a certain point and then for a period of time, the filter screen will automatically rise. During the rising process, the filter screen rotates to discharge impurities into the slag collection tank, achieving self-cleaning. Furthermore, during the cleaning process, the installation sleeve blocks the water outlet, preventing cleaning under running water conditions. This improves the rotation of the filter screen, increases centrifugal force, and ensures effective cleaning. During the rotation of the filter screen, the energy-storing locking structure releases the restriction on the lower position of the installation sleeve, allowing it to slide upwards automatically under elastic force. After the filter screen has finished cleaning the debris, the installation sleeve gradually opens the water outlet, and then filtration continues. The invention's provision of at least two filtration and sterilization chambers allows for continuous filtration, ensuring a continuous supply of filtered water for subsequent treatments.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figures 1 to 7 The present invention provides a structural diagram of a water purification device for antibacterial and antiviral filtration, comprising: a device body 1, wherein the device body 1 is provided with not less than two filtration and sterilization chambers 26; an inlet conduit 2 is provided at the top of the filtration and sterilization chamber 26 for inputting water to be treated into the filtration and sterilization chamber 26, and the bottom of the inlet conduit 2 is sealed; and an outlet hole 12 is provided on the side wall near the bottom of the inlet conduit 2.

[0033] A filter component is also provided on the inlet pipe 2. The filter component includes a mounting sleeve 4 that is elastically slidably disposed on the outside of the inlet pipe 2. Several first elastic elements 5 are arranged in a circular array on the outer side of the mounting sleeve 4. The end of the first elastic element 5 away from the mounting sleeve 4 is fixedly connected to the upper outer side of the filter screen 6. The filter screen 6 has a circular structure and the middle of the filter screen 6 is raised upward. The first elastic elements 5 are spiral elastic elements. The outer diameter of the mounting sleeve 4 is smaller than the outer diameter of the filter screen 6. The sliding trajectory of the mounting sleeve 4 covers the water outlet 12. An energy storage locking mechanism is also provided between the inlet pipe 2 and the mounting sleeve 4. The energy storage locking mechanism is used to lock the high and low positions of the mounting sleeve 4. A slag collection tank 10 is also provided on the inner wall of the filtration and sterilization chamber 26. The lower end of the filter screen 6 is slidably disposed in the slag collection tank 10. A slag discharge port 28 communicating with the inside of the slag collection tank 10 is also provided on the filtration and sterilization chamber 26. The slag discharge port 28 can be opened. A switch valve is also provided on the slag discharge port 28. The slag collection tank 10 is also equipped with a limiting mechanism to prevent the low-position filter screen 6 from rotating.

[0034] Specifically, the water to be filtered enters the filtration and sterilization chamber 26 through the inlet pipe 2. It first flows through the outlet hole 12 at the bottom of the inlet pipe 2 and then through the filter screen 6 for filtration. When a certain amount of impurities accumulate on the filter screen 6, its throughput decreases, and a certain amount of water remains on its surface. When the water reaches a certain level, the energy storage locking mechanism releases the position lock on the mounting sleeve 4. Under the weight of the mounting sleeve 4, it descends rapidly, blocking the outlet hole 12. Simultaneously, under the weight of the filter screen 6, the first elastic element 5 undergoes spiral deformation and is stretched, causing the filter screen 6 to move downwards relative to the mounting sleeve 4. When the mounting sleeve 4 descends to near the bottom, the limiting mechanism restricts the filter screen 6. When the mounting sleeve 4 descends to a set position, the energy storage locking mechanism locks the mounting sleeve 4 at its lowest position. At this point, the inlet pipe 2 will not supply water to the filter screen 6, and the water on the filter screen 6 is filtered out, leaving only water on its surface. After the filter screen 6 is nearly completely filtered, although it will automatically rise relative to the mounting sleeve 4, the first elastic element 5 cannot drive the filter screen 6 to rotate under the action of the limiting mechanism. When the water on the surface of the filter screen 6 is completely filtered, the filter screen 6 rises to the set height relative to the mounting sleeve 4, and the filter screen 6 is released from the locking of the limiting mechanism. The filter screen 6 rotates rapidly under the action of several first elastic elements 5, and then the debris on the surface of the filter screen 6 is centrifugally thrown into the slag collection tank 10, which can achieve the cleaning of the surface of the filter screen 6. At the same time, during the cleaning process, the mounting sleeve 4 blocks the water outlet 12 to prevent cleaning under running water, which can improve the rotation of the filter screen 6, increase the centrifugal force, and ensure the cleaning effect. During the rotation of the filter screen 6, the energy storage locking structure releases the restriction on the low position of the mounting sleeve 4, and the mounting sleeve 4 slides upward automatically under the action of elastic force. When the filter screen 6 has finished cleaning the debris, the mounting sleeve 4 gradually opens the water outlet 12 and then continues the filtration process. The present invention provides at least two filtration and sterilization chambers 26, which enables continuous filtration and provides filtered water for subsequent treatment.

[0035] In a preferred embodiment of the present invention, the filter screen 6 is disposed directly below the water inlet pipe 2.

[0036] In a preferred embodiment of the present invention, the mounting sleeve 4 is elastically mounted on the water inlet conduit 2 by at least one second elastic member 17, and the two ends of the second elastic member 17 are respectively fixedly mounted on the water inlet conduit 2 and the mounting sleeve 4. The second elastic member 17 can be a helical spring.

[0037] In a preferred embodiment of the present invention, a limiting platform 13 is also provided at the bottom of the water inlet conduit 2, which is used to limit the descent position of the mounting sleeve 4.

[0038] The present invention also includes an input pipe 25, the output end of which is connected to the top of the water inlet pipe 2 for inputting water to be treated into the water inlet pipe 2.

[0039] like Figure 1 As shown, in a preferred embodiment of the present invention, the slag collection tank 10 is formed by an mounting ring 7, an L-shaped fitting ring 9, and the side wall of the filter sterilization chamber 26. The mounting ring 7 is fixedly installed below the filter screen 6, and the L-shaped fitting ring 9 is fixedly installed on the side wall of the filter sterilization chamber 26. The L-shaped fitting ring 9 includes a side ring and a bottom ring fixedly installed on the side ring. The outer side of the bottom ring is fixedly installed on the side wall of the filter sterilization chamber 26, the inner side of the bottom ring is fixedly installed on the bottom of the side ring, and the outer side of the side ring is attached to the outer side of the mounting ring 7. The slag collection tank 10, formed by the mounting ring 7, the L-shaped fitting ring 9, and the side wall of the filter sterilization chamber 26, is used to collect debris that falls off the filter screen 6 during centrifugation.

[0040] like Figure 1 and Figure 5 As shown, in a preferred embodiment of the present invention, in order to restrict the rotation of the filter screen 6 when it is in a low position, and to prevent the filter screen 6 from rotating slowly and automatically during the water filtration process when the mounting sleeve 4 is in a low position, thus failing to achieve the effect of slag removal, a limiting mechanism is provided. Specifically, the limiting mechanism includes a plurality of limiting rods 29 arranged in an array on the outer side of the L-shaped mating ring 9, and a plurality of mating grooves 30 provided at the bottom of the mounting ring 7. The limiting rods 29 are used to insert into the mating grooves 30 when the mounting ring 7 is at or near the bottom. Specifically, when the mounting ring 7 descends with the filter screen 6, the mating groove 30 descends above the limiting rod 29. If the mating groove 30 is exactly above the limiting rod 29, the limiting rod 29 is inserted into the mating groove 30. If the mating groove 30 is not directly above the limiting rod 29, but because the first elastic element 5 is made of elastic material, the lower end of the mounting ring 7 will abut against the upper end of the limiting rod 29, and the first elastic element 5 will be compressed. When the water on the filter screen 6 decreases, the filter screen 6 will drive the mounting ring 7 to rotate. During the rotation, the mating groove 30 moves to above the third segment 20, and then the limiting rod 29 is inserted into the mating groove 30, which can also restrict the filter screen 6.

[0041] It should be noted that the number of limiting rods 29 is no less than four, five, six or more, and the number of mating grooves 30 is greater than the number of limiting rods 29. The number of mating grooves 30 is multiple of the number of limiting rods 29.

[0042] like Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, in a preferred embodiment of the present invention, the energy storage locking mechanism includes an elastic telescopic rod 21 elastically rotatably disposed on the side wall of the water inlet pipe 2 and a mating slide disposed on the inner wall of the mounting sleeve 4; the mating slide is vertically disposed and includes a first section 18, a second section 19 and a third section 20 from top to bottom; wherein the depth of the first section 18 is lower than that of the second section 19 and the third section 20, and a transition section is also disposed between the second section 19 and the third section 20, with the transition end being inclined; the extended end of the elastic telescopic rod 21 abuts against the lower edge of the mounting sleeve 4, and the mating slide is disposed directly above the elastic telescopic rod 21; the mounting end of the elastic telescopic rod 21 is elastically rotatably mounted on the side wall of the mounting groove 27; a first adsorption member 22 is disposed on both sides of the elastic telescopic rod 21, and a second adsorption member 23 is disposed on both sides of the elastic telescopic rod 21, the second adsorption member 23 is fixedly mounted on the side wall of the mounting groove 27, and the second adsorption member 23 and the first adsorption member 22 on the adjacent side are mutually adsorbed. Specifically, during the filtration process, when the inner wall of the mounting sleeve 4 abuts against the extended end of the elastic telescopic rod 21, and a certain amount of water accumulates on the filter screen 6, the squeezing force of the mounting sleeve 4 on the elastic telescopic rod 21 increases. When the squeezing force exceeds the attraction force between the first adsorption element 22 and the second adsorption element 23, the elastic telescopic rod 21 deflects, and the mounting sleeve 4 descends. Simultaneously, the elastic telescopic rod 21 passes through the third section 20, and then, under the action of elasticity, returns to a horizontal state, then passes through the second section 19. When the mounting sleeve 4 descends to its lowest position, the elastic telescopic rod 21 abuts against the upper end of the second section 19, limiting the mounting sleeve 4. At this time, the distal end of the elastic telescopic rod 21 abuts against the second section 19, thus satisfying the energy storage requirement of the mounting sleeve 4. A transition section is provided to facilitate the sliding of the elastic telescopic rod 21 from the third section 20 into the second section 19. The first adsorption element 22 and the second adsorption element 23 can be two magnets that attract each other.

[0043] Specifically, the elastic telescopic rod 21 includes an installation end and an extension end. The installation end is provided with a rotating shaft, which is rotatably mounted on the installation hole on the side wall of the installation groove 27. A torsion spring is sleeved on the outside of the rotating shaft. The two ends of the torsion spring are respectively fixedly installed on the side wall of the installation groove 27 and on the elastic telescopic rod 21. This realizes the elastic rotation installation of the elastic telescopic rod 21, so that the elastic telescopic rod 21 can return to its initial position after deflection.

[0044] It should be noted that the sliding track is recessed on the inner wall of the mounting sleeve 4.

[0045] In order to slow down the rising speed of the mounting sleeve 4 and provide enough time for the centrifugal deflection of the filter screen 6, a buffer mechanism is also provided between the water inlet pipe 2 and the mounting sleeve 4.

[0046] like Figure 1 and Figure 2As shown, in a preferred embodiment of the present invention, the buffer mechanism specifically includes a buffer cylinder 3 fixedly installed on the water inlet pipe 2; a piston 15 is slidably disposed inside the buffer cylinder 3; a guide piston rod 14 is fixedly installed on the mounting sleeve 4, the guide piston rod 14 passing through the piston 15 and the top of the buffer cylinder 3, and the guide piston rod 14 is fixedly connected to the piston 15; a one-way throttling orifice 16 is provided at the top of the buffer cylinder 3, the one-way throttling orifice 16 is used to unidirectionally throttle the air into the buffer cylinder 3; the throttling direction of the one-way throttling orifice 16 is towards the inside of the buffer cylinder 3. Thus, when the mounting sleeve 4 descends, air quickly enters the inside of the buffer cylinder 3 through the one-way throttling orifice 16, and when the mounting sleeve 4 rises, the rising speed of the piston 15 is slowed down by the throttling effect of the one-way throttling orifice 16, ensuring the centrifugal rotation time of the filter screen 6.

[0047] like Figure 1 As shown, in a preferred embodiment of the present invention, a plurality of disinfection lamps 11 are also provided on the inner wall of the filtration and sterilization chamber 26, which are used to sterilize the water; the main body 1 of the device is also provided with an outlet 24 for discharging the water from the filtration and sterilization chamber 26.

[0048] In order to further improve the quality of water treatment, the main body of the device 1 also includes an activated carbon filter and a filter membrane device, which are used to treat the water after it has been disinfected by the disinfection lamp 11 with activated carbon and filter membrane.

[0049] The working principle of this invention is:

[0050] The water to be filtered enters the filtration and sterilization chamber 26 through the inlet pipe 2. It first flows through the outlet hole 12 at the bottom of the inlet pipe 2 and then through the filter screen 6 for filtration. When a certain amount of impurities accumulate on the filter screen 6, its throughput decreases, and a certain amount of water remains on its surface. When the accumulated water reaches a certain level, the squeezing force of the mounting sleeve 4 on the elastic telescopic rod 21 increases. When the squeezing force exceeds the attraction force between the first adsorption element 22 and the second adsorption element 23, the elastic telescopic rod 21 deflects, releasing its position lock on the mounting sleeve 4. Under the influence of gravity, the mounting sleeve 4 descends rapidly, then blocks the outlet hole 12. Under the weight of the filter screen 6, the first elastic element 5 undergoes spiral deformation and is stretched. The filter screen 6 moves downwards relative to the mounting sleeve 4. When the mounting sleeve 4 descends to near the bottom, the limiting rod 29 on the L-shaped mating ring 9 inserts into the mating groove 30 on the bottom mounting ring 7 of the filter screen 6, restricting the rotation of the filter screen 6. During the descent of the mounting sleeve 4, the elastic telescopic rod 21 passes through the third section 20, and then, under elastic action, returns to a horizontal state, then passes through the second section 19. When the mounting sleeve 4 descends to its lowest position, the elastic telescopic rod 21 abuts against the upper end of the second section 19, thus affecting the mounting sleeve. 4. At the low position, the inlet pipe 2 will not deliver water to be treated onto the filter screen 6. When the water on the filter screen 6 is filtered out, and the water on the surface of the filter screen 6 is nearly filtered out, the filter screen 6 will automatically rise relative to the mounting sleeve 4. However, with the limit rod 29 inserted into the mating groove 30, the first elastic element 5 cannot drive the filter screen 6 to rotate. When the water on the surface of the filter screen 6 is completely filtered out, the filter screen 6 rises to the set height relative to the mounting sleeve 4. The limit rod 29 separates from the mating groove 30, releasing the restriction on the rotation of the filter screen 6. Under the action of several first elastic elements 5, the filter screen 6 rotates rapidly, and then the surface of the filter screen 6... The debris on the filter screen 6 is centrifuged and falls into the slag collection tank 10, which can clean the surface of the filter screen 6. At the same time, during the cleaning process, the mounting sleeve 4 blocks the water outlet 12 to prevent cleaning while the water is flowing. This can improve the rotation of the filter screen 6, increase the centrifugal force, and ensure the cleaning effect. During the rotation of the filter screen 6, the mounting sleeve 4 overcomes the restriction of the elastic telescopic rod 21 under the action of elasticity. The elastic telescopic rod 21 deflects again, releasing the restriction on the low position of the mounting sleeve 4. The mounting sleeve 4 automatically slides upward under the action of elastic force. After the filter screen 6 has finished cleaning the debris, the mounting sleeve 4 gradually opens the water outlet 12 and then continues the filtration process.
