Description

Technical Field

[0001] This invention relates to the field of pet drinking equipment technology, specifically a pet drinking water storage device with a circulating filtration mechanism. Background Technology

[0002] As people's living standards improve, pets have gradually become important members of family life, and the health care of pets has attracted more and more attention from owners. As a basic need for pets' daily life activities, the safety of their water quality and the stability of their supply directly affect their health. Traditional pet drinking water storage devices mainly use open-mouth water bowls or automatic water replenishment devices with simple water storage functions. Among them, open-mouth water bowls have a simple structure, usually consisting of only a single bowl-shaped container, which can meet the pet's immediate drinking needs. However, the open design makes it easy for external contaminants such as dust, hair, and pet saliva residue to directly enter the water. At the same time, the large surface area of ​​water in contact with air makes it easy for bacteria and algae to grow. Long-term drinking of such water by pets can easily lead to health problems such as gastrointestinal diseases and urinary tract infections. Secondly, while automatic water replenishment devices with simple water storage functions can solve the problem of frequent water replenishment, they lack an effective water purification mechanism. Pets generate a lot of drinking wastewater after drinking, which is mostly discharged directly, resulting in water waste. Therefore, we propose a pet drinking water storage device with a circulating filtration mechanism to solve the above problems. Summary of the Invention

[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: Figure 1-11 As shown, the present invention provides a pet drinking water storage device with a circulating filtration mechanism, including a device frame 1, a drinking mechanism 2 at the bottom of the device frame 1, and a water storage tank 3 fixedly installed at the top of the device frame 1. The drinking mechanism 2 includes a drinking tray 21, which is fixedly attached to the bottom of the outer frame 1. The drinking tray 21 has a ring-shaped structure, allowing drinking water to be discharged into it, making it convenient for pets to drink from the water. It also facilitates the subsequent recycling of any remaining drinking water and simultaneous cleaning of the inner wall of the drinking tray 21 by rotating it. A bottom tube 22 is integrally formed in the middle of the drinking tray 21. The top is provided with a top tube 23, and the top of the top tube 23 is integrally formed with a dust cover 24. The bottom end of the dust cover 24 contacts the top of the drinking tray 21. The dust cover 24 is designed as a semi-circular structure. Half of the drinking tray 21 is provided with a semi-circular groove 211. In the initial state, the dust cover 24 is located on the side of the drinking tray 21 away from the semi-circular groove 211. The dust cover 24 protects half of the drinking tray 21 from dust, preventing external dust from falling into the drinking tray 21 and causing pollution when the drinking tray 21 is not in use. Cleaning scrapers 241 are fixedly mounted on both ends of the dust cover 24. The cleaning scrapers 241 contact the inner walls of the drinking tray 21 and the bottom tube 22. By setting the cleaning scrapers 241 and contacting the inner walls of the drinking tray 21 and the bottom tube 22, the inner walls of the drinking tray 21 need to be cleaned after the drinking tray 21 is used. At this time, the dust cover 24 is rotated by controlling the top tube 23 to rotate, thereby driving the cleaning scrapers 241 to rotate on the inner walls of the drinking tray 21 and the bottom tube 22. The cleaning scrapers 241 clean the inner walls of the drinking tray 21 and the bottom tube 22 simultaneously, and push the remaining drinking water in the drinking tray 21 to the semi-annular groove 211 for subsequent recycling. A bottom ring frame 25 is fixedly installed at the bottom end of the drinking tray 21, and a filter element 26 is fixedly fastened on the side of the bottom ring frame 25 near the semi-ring groove 211. The bottom of the water tank 3 is integrally formed with a bottom cylinder 31, which extends to the middle of the bottom tube 22. The top water inlet of the water tank 3 is threaded with a tank cover 32. By rotating to open the tank cover 32, the pet's drinking water is introduced into the water tank 3 through the top water inlet.

[0032] A front sealing plate 11 is fixedly installed on the top inner side of the outer frame 1 of the device. The top of the dust cover 24 is movably snapped between the front sealing plates 11. The front sealing plate 11 is used to seal the front end of the outer frame 1 of the device and the dust cover 24 without affecting the rotation of the dust cover 24 between the front sealing plates 11. A rear cover 12 is detachably installed on the side of the outer frame 1 of the device close to the filter element 26 by screws, which facilitates the cleaning or replacement of the filter element 26 by removing the rear cover 12. A sensor 13 is fixedly installed on the side of the outer frame 1 of the device away from the rear cover 12. The entire pet drinking and water storage device includes a trigger module, a control module, a drinking module, a filtration module, and a wastewater discharge module. When a pet needs to drink water, it will approach the device, and the sensor 13 in the trigger module will receive a signal. The control module will then control the drinking module to dispense water, allowing the pet to drink. After drinking, the pet will move away from the device, and the sensor 13 in the trigger module will receive a signal again. The control module will then control the filtration module to recycle and filter the remaining water. Subsequently, the control module will control the wastewater discharge module to flush out large impurities filtered in the filtration module.

[0033] The bottom of the bottom tube 22 is fixedly fitted with a water outlet pipe 221. A water pump 222 is fixedly installed at the inner end of the water outlet pipe 221. A connecting pipe 223 is fixedly installed at the end of the water pump 222 away from the water outlet pipe 221. The connecting pipe 223 is vertically installed at the bottom of the bottom tube 31. A water flow isolation frame 224 is fixedly fitted at the outer end of the water outlet pipe 221. By turning on the water pump 222, drinking water in the water storage tank 3 is discharged into the drinking dish 21 through the connecting pipe 223 and the water outlet pipe 221, making it convenient for pets to drink the drinking water in the drinking dish 21. The water flow isolation frame 224 at the outer end of the water outlet pipe 221 can prevent external impurities from entering the water outlet pipe 221 in reverse and causing pollution.

[0034] The filter element 26 includes a filter ring frame 261, which is fixedly snapped into the bottom ring frame 25. One end of the filter ring frame 261 is integrally formed with an end sealing plate 2611. By setting the end sealing plate 2611 at one end of the filter ring frame 261, the end sealing plate 2611 can block one end of the filter ring frame 261, while the other end of the filter ring frame 261 is open, so that the filtered water can flow into the bottom ring frame 25 through the other end of the filter ring frame 261. Multiple filter elements 262 are movably mounted in the filter ring frame 261. The filter elements 262 mainly include nylon filter screens, activated carbon filter elements, and ion exchange resin filter elements. A mounting top plate 263 is fixedly installed at the top of each filter element 262. The mounting top plate 263 is movably engaged with the inner top of the filter ring frame 261. A top cover 264 is fixedly mounted to the top of the filter ring frame 261 by screws. The mounting top plate 263 is movably engaged with the bottom of the top cover 264, facilitating the installation of the top plate 262 by removing the top cover 264. 3. For the disassembly, cleaning or replacement of multiple filter elements 262, a recovery port 2601 is formed on the side of the top of the filter ring frame 261 near the end sealing plate 2611. The inner wall of the drinking tray 21 and the bottom tube 22 is cleaned simultaneously by rotating the cleaning scraper 241, and the remaining drinking water in the drinking tray 21 is pushed to the position of the semi-ring groove 211 until one side of the cleaning scraper 241 is moved to one end of the recovery port 2601, and the remaining drinking water and impurities are gradually fed into the filter ring frame 261 through the recovery port 2601 for recycling.

[0035] An auxiliary longitudinal pipe 4 is fixedly installed on the bottom side of the water storage tank 3 near the recovery port 2601. An auxiliary pump 41 is fixedly installed at the bottom of the auxiliary longitudinal pipe 4. A cleaning cross frame 42 is fixedly installed at the output end of the auxiliary pump 41. Multiple cleaning nozzles 421 are evenly distributed at the bottom of the cleaning cross frame 42. When one side of the cleaning scraper 241 moves to one end of the recovery port 2601, some impurities may remain on the surface of the cleaning scraper 241. At this time, the auxiliary pump 41 can be turned on, and the drinking water in the water storage tank 3 is introduced into the cleaning cross frame 42 through the auxiliary longitudinal pipe 4 and evenly sprayed onto the surface of the cleaning scraper 241 through the multiple cleaning nozzles 421 to rinse and clean the impurities remaining on the surface of the cleaning scraper 241. The wastewater generated flows directly into the filter ring frame 261 through the recovery port 2601 for recycling.

[0036] A recovery horizontal pipe 28 is fixedly fastened to the inner side of the bottom ring frame 25 away from the sewage pipe 27. A recovery pump 281 is fixedly installed at the end of the recovery horizontal pipe 28, and a recovery vertical pipe 282 is fixedly installed at the output end of the recovery pump 281. The top end of the recovery vertical pipe 282 is fixedly installed at the bottom end of the bottom cylinder 31. After the remaining drinking water and wastewater generated during cleaning are recovered, the recovery pump 281 is turned on at the same time. The water flowing into the filter ring frame 261 is filtered through a nylon filter screen to remove large particles such as hair and food residue, an activated carbon filter to adsorb odors, residual chlorine and small organic matter in the water, and an ion exchange resin filter to soften the water and remove heavy metal ions. After that, the water is introduced into the bottom cylinder 31 through the recovery horizontal pipe 28 and the recovery vertical pipe 282 for recycling and reuse. This realizes the recycling and reuse of remaining water and wastewater, reduces water waste, and further improves the overall effect of the device.

[0037] A horizontal sealing plate 242 is vertically installed at the bottom of the cleaning scraper 241 located away from the recycling port 2601. The bottom end of the horizontal sealing plate 242 contacts the inner surface of the drinking tray 21. The size of the horizontal sealing plate 242 is larger than the size of the recycling port 2601. After the pet finishes drinking, the top tube 23 is rotated to drive the dust cover 24 to rotate, so that the dust cover 24 is located on the side of the drinking tray 21 away from the semi-annular groove 211. The dust cover 24 protects half of the drinking tray 21 from dust. At this time, the horizontal sealing plate 242 is located at the recycling port 2601 and seals the recycling port 2601. A drain pipe 27 is provided on the side of the bottom ring frame 25 near the filter element 26. The drain pipe 27 movably passes through the outer frame 1 of the device. The inner end of the drain pipe 27 is threaded and installed in the middle of the filter ring frame 261. A suction pump 271 is fixedly installed at the end of the drain pipe 27 away from the bottom ring frame 25. A sludge storage frame 272 is fixedly installed at the output end of the suction pump 271. After multiple filter elements 262 have been filtering for a period of time, the nylon filter screen will filter out a lot of large particles such as hair and food residue. At this time, the suction pump 271 is turned on, and some of the remaining filtered water in the bottom ring frame 25 is reversed and sucked through the ion exchange resin filter element, activated carbon filter element and nylon filter screen in sequence to wash away the large particles filtered by the nylon filter screen. The water is then sucked into the sludge storage frame 272 through the drain pipe 27. This reverses the cleaning of the filter elements 262 to prevent too many large particles from affecting the filtration process and further improves the overall performance of the device.

[0038] The bottom end of the top tube 23 is integrally formed with a mounting ring 231, which is movably engaged with the top end of the bottom tube 22. An internal gear ring 232 is fixedly mounted in the middle of the inner side of the top tube 23. A rotating seat 233 is fixedly mounted on the top of the inner side of the bottom tube 22. A drive shaft 234 is rotatably mounted on the rotating seat 233. A drive gear 235 is fixedly mounted on the top of the drive shaft 234. The drive gear 235 and the inner side of the internal gear ring 232 are meshed. A drive motor 236 is fixedly mounted at the bottom end of the rotating seat 233. The drive end of the drive motor 236 and the bottom end of the drive shaft 234 are fixedly mounted. By turning on the drive motor 236, the drive shaft 234 and the drive gear 235 are driven to rotate, thereby driving the internal gear ring 232 to rotate, and thus controlling the rotation of the top tube 23 to drive the dust cover 24 to rotate.

[0039] Working principle: In the initial state, the dust cover 24 is located on the side of the drinking tray 21 away from the semi-annular groove 211. The dust cover 24 protects half of the drinking tray 21 from dust, preventing external dust from falling into the drinking tray 21 and causing pollution when the drinking tray 21 is not in use. By rotating the lid 32 to open it, the pet's drinking water is introduced into the water tank 3 through the water inlet at the top of the water tank 3; When the pet needs to drink water, it will approach the device. At this time, the sensor 13 is sensed and the drive motor 236 is turned on to drive the drive shaft 234 and drive gear 235 to rotate, thereby driving the internal gear ring 232 to rotate, which in turn controls the top tube 23 to rotate and drives the dust cover 24 to rotate. The dust cover 24 moves to the position of the semi-annular groove 211, and the drinking tray 21 is exposed. Then, the water pump 222 is turned on, and the drinking water in the water tank 3 is discharged into the drinking dish 21 through the connecting pipe 223 and the water outlet pipe 221, so that the pet can drink the drinking water in the drinking dish 21. After the pet finishes drinking, it moves away from the device. At this time, the sensor 13 is sensed again, and the drive motor 236 is turned on to drive the drive shaft 234 and drive gear 235 to rotate, thereby driving the internal gear ring 232 to rotate. This, in turn, controls the top tube 23 to rotate, causing the dust cover 24 to rotate again. The remaining drinking water in the drinking tray 21 is pushed to the position of the semi-ring groove 211 until one side of the cleaning scraper 241 is moved to one end of the recycling port 2601. The remaining drinking water and impurities are gradually recycled into the filter ring frame 261 through the recycling port 2601. When one side of the cleaning scraper 241 moves to one end of the recovery port 2601, some impurities may remain on the surface of the cleaning scraper 241. At this time, the auxiliary pump 41 can be turned on, and the drinking water in the water storage tank 3 is introduced into the cleaning cross frame 42 through the auxiliary longitudinal pipe 4 and sprayed evenly on the surface of the cleaning scraper 241 through multiple cleaning nozzles 421 to rinse and clean the impurities remaining on the surface of the cleaning scraper 241. The wastewater generated flows directly into the filter ring frame 261 through the recovery port 2601 for recycling. After the remaining drinking water and wastewater generated from the cleaning are recycled, the recycling pump 281 is turned on at the same time. The recycled water flows into the filter ring frame 261 and passes through the nylon filter screen to filter out large particles such as hair and food residue, the activated carbon filter to adsorb odors, residual chlorine and small organic matter in the water, and the ion exchange resin filter to soften the water and remove heavy metal ions. Then, it is introduced into the bottom cylinder 31 through the recycling horizontal pipe 28 and the recycling vertical pipe 282 for recycling and reuse. This realizes the recycling and reuse of the remaining water and wastewater, reducing water waste. After the circulation filtration and recycling is completed, the top tube 23 is rotated again to drive the dust cover 24 to rotate, so that the dust cover 24 is located on the side of the drinking tray 21 away from the semi-annular groove 211. The dust cover 24 protects half of the drinking tray 21 from dust. At this time, the horizontal sealing plate 242 is located at the recycling port 2601 and the horizontal sealing plate 242 seals the recycling port 2601. After multiple filter cartridges 262 have been filtering for a period of time, the nylon filter screen will filter out a significant amount of large particles such as hair and food residue. At this point, the suction pump 271 is turned on to reverse-pump the remaining filtered water in the bottom ring frame 25, allowing it to pass sequentially through the ion exchange resin filter cartridge, activated carbon filter cartridge, and nylon filter screen. This process washes away the large particles filtered by the nylon filter screen and drains them into the sludge storage frame 272 through the drain pipe 27. This reverse-pump cleaning of the filter cartridges 262 prevents excessive large particles from affecting the filtration process and further improves the overall performance of the device. Subsequently, the top plate 263 and multiple filter elements 262 can be disassembled, cleaned, or replaced by removing the rear cover 12 and the top cover 264.
