Description

Technical Field

[0001] This utility model relates to the technical field of pet products, and in particular to an ozone pet water dispenser. Background Technology

[0002] As is well known, a pet water fountain is a water circulation device that generally includes a water tank, a tray mounted on the tank, and a pump connected to the tank. When the pump operates, it draws water from the tank onto the tray. When the water level in the tray reaches a certain height, excess water flows back into the tank through holes in the tray, creating a water circulation system. However, currently available pet water fountains, especially in winter, often have excessively cold water in the tank. Drinking cold water can easily cause gastrointestinal discomfort for pets, affecting the user experience. Furthermore, existing pet water fountains generally use ultraviolet (UV) light for sterilization. This method typically requires continuous UV irradiation of the area to be sterilized for more than 6 hours to achieve sterilization. For water-circulating pet water fountains, the UV lamp needs to be continuously on, increasing energy consumption and reducing battery life. Moreover, UV sterilization has a low inactivation rate for cell spores and viruses, resulting in poor sterilization effectiveness. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] See attached document Figure 1-9 An ozone pet water dispenser 100 is described in this embodiment of the utility model.

[0042] Specifically, the water-splitting ozone generator 4 is a low-pressure water-splitting ozone generator. This generator uses low-voltage DC current to conduct electricity between the positive and negative electrodes of a solid-state membrane electrode to electrolyze deionized water. At a special anolyte interface, water is separated into hydrogen and oxygen molecules through proton exchange, with the chemical formula: 2H₂O → 2H₂ + O₂. Hydrogen is directly emitted from the cathode interface, while oxygen molecules gain energy at the anode interface due to electron excitation from the high-density current and polymerize into ozone, with the chemical formula: 3O₂ → 2O₃. Furthermore, the low-pressure water-splitting method produces ozone with oxygen and hydrogen as byproducts, without nitrogen oxides (NOx) or other harmful substances.

[0043] Because most pathogenic bacteria and microorganisms are anaerobic, such as Helicobacter pylori, an anaerobic pathogen that thrives in the gums, pets infected with it are prone to indigestion and gastrointestinal problems; another example is Porphyromonas gingivalis, an important anaerobic coccidia pathogen in the oral cavity, which can easily cause periodontal problems in pets. Ozone has extremely strong oxidizing properties. After O3 dissolves in water, it can react with various biomolecules within the cells of bacteria, viruses, and other microorganisms in the water, thereby destroying and inhibiting the replication, reproduction, and growth of bacteria and microorganisms, thus killing harmful bacteria and inhibiting the growth of harmful microorganisms in the water, achieving a bactericidal effect. Furthermore, due to the living habits of pets, germs are always around their mouths, and they introduce germs into the water every time they drink. Ozone dissolved in water can kill these germs, providing pets with a sterile water source. The unstable O3 easily reduces to oxygen, increasing the dissolved oxygen content in the water, allowing pets to drink clean water rich in oxygen and sterile.

[0044] Furthermore, long-term consumption of water with low oxygen content, such as boiled water, can actually promote the growth of anaerobic bacteria in the gut, leading to a gradual decline in the oxygen absorption function of the gastric and intestinal mucosa, which is detrimental to health. In contrast, this embodiment provides pets with oxygen-rich and sterile drinking water, which can effectively promote pet metabolism and benefit pet health.

[0045] Low-pressure hydrolyzed ozone generators produce higher concentrations of ozone, resulting in faster sterilization compared to ultraviolet lamps and a higher inactivation rate for cell spores and viruses. This improves sterilization efficiency and purifies water more quickly, providing clean water for pets. Furthermore, once a certain ozone concentration is reached, the low-pressure hydrolyzed ozone generator does not need to be continuously operated. It can be turned on intermittently to maintain the ozone concentration, thus reducing energy consumption and saving energy. In battery-powered ozone pet water fountains 100, this extends battery life.

[0046] Based on this, this embodiment uses a hydrolyzed ozone generator to produce ozone to sterilize the liquid in the container, and also increases the oxygen content in the water, thereby providing pets with sterile and oxygenated drinking water, which is more beneficial to the pets' health. Moreover, compared with ultraviolet light, ozone sterilizes faster and has a higher inactivation rate for cell spores and viruses, thereby improving sterilization efficiency and purifying water sources more quickly.

[0047] This embodiment incorporates a heating unit 6 on the ozone pet water fountain 100 to heat the liquid in the cavity 24, preventing pets from experiencing gastrointestinal discomfort due to cold water in winter and improving the utilization rate of the ozone pet water fountain 100. Furthermore, this embodiment includes a hydrolyzed ozone generator 4 on the ozone pet water fountain 100 to sterilize the liquid in the cavity 24, providing clean water for the pets. Additionally, this embodiment separates the control host 1 from the main body 2 for easier testing of the control host 1 and convenient replacement of the first circuit board 15 if damaged. Moreover, this embodiment features a pump body 3 and a return water inlet 211. When the pump body 3 is operating, it draws liquid from the cavity 24 into the drinking trough 212. When the water level in the drinking trough 212 reaches a certain height, the water flows back into the cavity 24 through the return water inlet 211, creating flowing water to attract the pet to drink and ensuring the pet receives clean water.

[0048] Specifically, the hydrolyzed ozone generator 4 is a miniature low-pressure hydrolysis high-concentration pure O3 gas generation device, such as the one from Ozon Systems GmbH (O3 Systems GmbH) in Stuttgart, Germany.

[0049] In this embodiment, the main body 2 may be provided with a temperature detection unit 12 for detecting the temperature of the liquid water in the cavity 24 or the heating temperature of the heating unit 6. The temperature detection unit 12 is electrically connected to the first circuit board 15 to control the water in the cavity 24 at a certain temperature, preventing the water temperature from being too high or too low. The temperature detection unit 12 may be a temperature sensor, a thermistor, etc. Of course, in embodiments without a temperature detection unit 12, the temperature of the heating unit 6 can be controlled by adjusting the output power to the heating unit 6 at the time of manufacture of the ozone pet water dispenser 100.

[0050] In one embodiment, the main body 2 has a first cavity 25 below the cavity 24, and the heating unit 6 is disposed in the first cavity 25.

The battery 5 is disposed within the first cavity 25 and located on one side of the heating unit 6. The battery 5 is used to supply power to the first circuit board 15, preventing the ozone pet water fountain 100 from being connected to an external power source via the power cord 31, thus avoiding the power cord 31 tripping over pets and affecting the user experience. Specifically, the battery 5 is a rechargeable battery 5, and the housing 11 is provided with a charging interface 18 electrically connected to the first circuit board 15. The charging interface 18 is used to connect to an external power source, and the first circuit board 15 processes the power supplied to the charging interface 18 to charge the battery 5.

The battery 5 is located on the side of the water-splitting ozone generator 4 away from the heating unit 6. The second circuit board 7 is disposed within the first cavity 25. The second circuit board 7 facilitates the electrical connection of the first circuit board 15 to the heating unit 6, the water-splitting ozone generator 4, and the battery 5, and allows for a more orderly distribution of the conductive components connecting the first circuit board 15 to these components.

[0053] In one embodiment, a first mounting groove 26 is provided on the top of the main body 2, and the housing 11 is at least partially disposed in the first mounting groove 26 so that the control host 1 can be assembled onto the main body 2.

[0054] In one embodiment, an embedding protrusion 1131 is provided on the outer side wall of the housing 11, and an embedding groove 216 adapted to the embedding protrusion 1131 is formed on the side wall of the first mounting groove 26 of the main body 2. The embedding protrusion 1131 is placed in the embedding groove 216 when the housing 11 and the main body 2 are assembled, so as to detachably and stably assemble the control host 1 onto the main body 2. Of course, in other embodiments, the housing 11 can also be detachably connected to the main body 2 by means of magnetic attraction, snap-fit, sliding groove, etc.

[0055] In one embodiment, the housing 11 is provided with a probe 14 electrically connected to the first circuit board 15. The main body 2 is provided with a conductive pin 8 electrically connected to the second circuit board 7 at the position corresponding to the probe 14. The probe 14 contacts the conductive pin 8 when the housing 11 is assembled into the first mounting groove 26. This allows for replacement of only the control host 1 if it is damaged, facilitates testing of the control host 1, and reduces the volume occupied by the ozone pet water dispenser 100 during manufacturing and testing.

[0056] In one embodiment, the main body 2 is further provided with a second cavity 28 located next to the cavity 24. The second cavity 28 is located between the first mounting groove 26 and the first cavity 25. The second cavity 28 is located on one side of the cavity 24.

The second cavity 28 is independently provided for installing the conductive needle 8, which can effectively prevent the conductive needle 8 from getting wet.

[0057] In one embodiment, a first pillar 282 is provided inside the second cavity 28. The top of the first pillar 282 extends to the surface of the main body 2 near the first mounting groove 26. A first limiting hole 281 communicating with the first mounting groove 26 and the first cavity 25 is formed on the first pillar 282. One end of the conductive pin 8 passes through the first limiting hole 281 and is electrically connected to the second circuit board 7. A waterproof glue pillar 81 is formed between the first pillar 282 and the conductive pin 8 by potting glue. The waterproof glue pillar 81 prevents water from entering the first cavity 25 from the first limiting hole 281, thus achieving a waterproof function.

[0058] In one embodiment, the control host 1 further includes an adapter plate 16 located below and electrically connected to the first circuit board 15.

The first bottom shell 23 is disposed at the bottom of the intermediate shell 11, and the first bottom shell 23 is connected to the intermediate shell 11 to form a first cavity 25. A second cavity 28 is located on the intermediate shell 11. A drinking trough 212 and a return water inlet 211 are formed on the tray 21, so that the second cavity 28 is located between the first mounting groove 26 and the first cavity 25. This structure is simple, convenient for the manufacture of the main body 2, and facilitates the placement of the second circuit board 7, battery 5, and heating unit 6 in the first cavity 25. It also facilitates the placement of the hydrolyzed ozone generator 4 on the intermediate shell 11 to sterilize the liquid in the cavity 24.

[0060] Specifically, the leads of the positive and negative electrode plates on the hydrolyzed ozone generator 4 can pass through the cavity 24 and the intermediate housing 11, and then be placed inside the first cavity 25 and electrically connected to the second circuit board 7. The leads and the intermediate housing 11 can be sealed using a sealing ring or adhesive to prevent liquid from entering the first cavity 25. Alternatively, the positive and negative electrode plates on the hydrolyzed ozone generator 4 can be electrically connected to the second circuit board 7 via wires.

[0070] In one embodiment, the switching unit 17 includes a water outlet switch 171 electrically connected to the first circuit board 15 and operated by the user. The first circuit board 15 has three water outlet modes: induction water outlet, continuous water outlet, and intermittent water outlet. Specifically, the user can switch the water outlet mode via the water outlet switch 171; that is, the first circuit board 15 switches the water outlet mode according to the electrical signal fed back by the water outlet switch 171, thereby controlling the pump body 3 to operate according to the water outlet module. When the water outlet mode is induction water outlet, that is, when the detection unit 12 detects a pet approaching, the first circuit board 15 drives the pump body 3 to operate; when the detection unit 12 does not detect a pet, the first circuit board 15 stops driving the pump body 3 to operate. When the water outlet mode is continuous water outlet, the first circuit board 15 continuously drives the pump body 3 to operate, that is, the pump body 3 continuously draws water from the cavity 24 to the drinking trough 212. When the water output mode is intermittent, the first circuit board 15 drives the pump body 3 to work at preset intervals. For example, if the preset interval is 30 minutes, the first circuit board 15 will drive the pump body 3 to work for a certain period of time every 30 minutes. If the certain period of time is 10 minutes, the first circuit board 15 will drive the pump body 3 to work for 10 minutes after every 30 minutes and then stop driving the pump body 3. The certain period of time can be set according to needs, such as 5 minutes, 20 minutes, etc.

[0071] In one embodiment, the switching unit 17 includes a sterilization control switch 172 electrically connected to the first circuit board 15 and operated by the user. The first circuit board 15 has four sterilization modes: manual sterilization, sterilization every half hour, sterilization every hour, and sterilization every two hours. The user can switch the sterilization mode using the sterilization control switch 172, and the first circuit board 15 switches the water outlet mode based on the electrical signal fed back from the water outlet switch 171. When the sterilization mode is manual sterilization, the switching unit 17 also includes a sterilization switch 173 electrically connected to the first circuit board 15. The user operates the sterilization switch 173, and the first circuit board 15 drives the hydrolyzed ozone generator 4 to operate or shut it down based on the electrical signal fed back from the sterilization switch 173. When the sterilization mode is set to sterilize every half hour, the first circuit board 15 drives the hydrolyzed ozone generator 4 to work for a certain period of time every half hour. For example, if the certain period is 10 minutes, the first circuit board 15 drives the hydrolyzed ozone generator 4 to work for 10 minutes every half hour, then turns off the hydrolyzed ozone generator 4, and drives it to work again after half an hour.
