Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, specifically to a faucet antibacterial device. Background Technology

[0002] As people's living standards improve, their requirements for drinking water quality are also increasing. Generally, tap water that meets standards is sterile when it leaves the treatment plant and can be consumed directly. However, in reality, due to aging water pipes and poor management of water storage tanks at transfer stations, secondary pollution can occur during transportation and transfer, leading to excessive bacterial counts. Direct consumption of this water poses certain health risks, so most families boil the water before drinking; some families have switched to bottled water; and given the frequent reports of unreliable bottled water quality on the market, many have turned to water purification equipment. This equipment uses filtration, purification, and ultraviolet sterilization to treat tap water or bottled water into drinkable water. While purified or sterilized water should be sterile inside the faucet valve, the outlet is exposed to the outside air. Once bacteria from the air enter the water through the outlet (faucet), they can quickly multiply in the pipes, causing rapid secondary pollution of the purified water.

[0003] Existing methods for sterilizing faucets generally involve installing ultraviolet lamps directly at the faucet for periodic sterilization and disinfection. For example, the sterilizing faucet, sterilizing tap, and water purification sterilization and sterilization method disclosed in patent application number CN201410050288.3 are equipped with power generation and storage devices, using water flow to generate electricity for ultraviolet disinfection. However, drinking water pipes are characterized by frequent and small-volume use in practical applications, resulting in low water flow and low power generation. When the faucet is used frequently in a short period of time, bacteria do not have an opportunity to multiply. However, when the faucet is not used for a long time, the storage device may have insufficient power, leading to insufficient bacterial reproduction capacity. Furthermore, long-stemmed faucets retain a lot of water in the pipes, which will directly bring out a large number of bacteria during the next use, indicating room for improvement.

A water outlet hose is fixedly connected to the bottom of the external tube. A water inlet hole is opened on the bottom side of the inner tube. A water inlet seat is fixedly connected to the lower part of the antibacterial seat. A concave groove is opened above the water inlet seat. A water blocking disc is set above the concave groove. A connecting rod is fixedly connected to the upper part of the water blocking disc at a position corresponding to the inner tube. A water inlet plug is fixedly connected to the top of the connecting rod. A limit sleeve is fixedly fitted on the bottom outer side of the water inlet plug.

[0009] A connector is fixedly connected to the inner side of the water outlet. A first ultraviolet lamp ring is provided on the inner side of the connector near the water outlet. A first wiring port is provided on the upper part of the connector corresponding to the first ultraviolet lamp ring. A foam generator is provided inside the end of the connector away from the water outlet. A second ultraviolet lamp ring is provided on the upper part of the antibacterial base. A second wiring port is provided on the upper part of the antibacterial base near the first water inlet, corresponding to the second ultraviolet lamp ring.

[0010] Preferably, the inner and outer sides of the threaded sleeve are respectively provided with an inner ring sleeve and an outer ring sleeve. The inner side of the inner ring sleeve is movably sleeved with the outer side of the antibacterial seat. The inner side of the outer ring sleeve of the threaded sleeve is threadedly connected to the threaded seat. The top outer side of the threaded sleeve is provided with an external hexagonal ridge.

[0011] Preferably, a magnetic paddle is rotatably connected inside the connector between the first ultraviolet lamp ring and the foam generator, and a Hall sensor is provided on the outer side of the magnetic paddle.

[0012] Preferably, the first ultraviolet lamp ring is electrically connected to a power supply and a controller via a wire and a first terminal.

[0013] Preferably, the second ultraviolet lamp ring and the Hall sensor are both electrically connected to the power supply and the controller via wires and a second terminal.

[0014] Preferably, the tops of the outer pipe and the inner pipe are interconnected, the end of the outlet hose away from the outer pipe is fixedly connected to the drainage pipe, and the outlet of the outlet hose is much lower than the inlet of the inner pipe.

[0015] Preferably, the shape of the water-blocking disc corresponds to the shape of the concave groove, and a mirror layer is provided on the concave surface above the water-blocking disc.

[0016] Preferably, the ultraviolet wavelength generated by the first ultraviolet lamp ring is 185 nanometers, and the ultraviolet wavelength generated by the second ultraviolet lamp ring is 253.7 nanometers.

[0017] Working Principle: When the faucet is in use, this invention utilizes the enlarged inner diameter of the antibacterial seat to create a slow-flow effect, reducing the water flow velocity and facilitating direct sterilization with the 253.7 nm ultraviolet light from the second ultraviolet lamp ring. Simultaneously, when water flows out of the faucet, the water-blocking disc uses the water flow force to block the inlet plug, preventing leakage. When the faucet is closed, the 185 nm short-wave ultraviolet light from the first ultraviolet lamp ring generates ozone. The weight of the water-blocking disc causes the inlet plug to descend, opening the inlet. The outer and inner auxiliary tubes, together with the outlet hose, use the siphon principle to extract the water stored inside the long neck tube, preventing the growth of bacteria from stagnant water. Furthermore, during the extraction of water, the ozone generated by the first ultraviolet lamp ring is simultaneously drawn into the long neck tube, effectively improving the disinfection and antibacterial effects.

[0018] (III) Beneficial Effects

[0019] This invention provides a faucet antibacterial device. It has the following beneficial effects:

[0020] 1. By setting a first ultraviolet lamp ring at the water outlet and a second ultraviolet lamp ring inside the antibacterial seat, the present invention can not only directly kill bacteria through the 253.7 nanometer ultraviolet light of the second ultraviolet lamp ring, but also generate ozone through the 185 nanometer short-wave ultraviolet light of the first ultraviolet lamp ring, so as to achieve a long-term antibacterial effect, thereby enhancing the practicality of the present invention.

[0021] 2. The long neck tube of the present invention is provided with an outer tube and an inner tube. In conjunction with the water outlet hose, the water stored inside the long neck tube can be extracted by using the siphon principle after the faucet is turned off, so as to avoid the occurrence of bacteria growth in the water. At the same time, when the water is extracted, the ozone generated by the first ultraviolet lamp ring can be drawn into the interior of the long neck tube, which can effectively improve the disinfection and antibacterial effect and enhance the practicality of the present invention.

[0022] 3. This invention features a concave groove and a water-blocking disc, which, together with a connecting rod and an inlet plug, can concentrate light through the reflective effect of the concave surface of the water-blocking disc, directing some ultraviolet rays into the long neck tube for direct sterilization. When water is flowing from the faucet, the water flow force can block the inlet plug to prevent leakage. When the faucet is closed, the weight of the water-blocking disc causes the inlet plug to descend, opening the inlet and creating a siphon effect, which facilitates the extraction of stored water and the intake of ozone, thus improving the antibacterial effect.
