Description

Technical Field

[0001] This utility model relates to the field of direct drinking water machine technology, specifically to a direct drinking water machine water tank with a sterile structure. Background Technology

[0002] A direct drinking water purifier is a household water purification device installed in homes, offices, and other places to purify tap water to a level suitable for direct drinking. It typically includes a multi-stage purification system, such as ultrafiltration, activated carbon filtration, and RO reverse osmosis membrane technology, to remove harmful substances, bacteria, viruses, etc., providing a purer and safer drinking water source. To effectively isolate the water from external air and bacterial contamination and prevent secondary pollution of the water tank, this invention proposes a sterile direct drinking water purifier tank.

[0003] According to a search, Chinese patent document CN206675419U discloses a sterile direct drinking water tank. It features an air inlet to balance the pressure inside the tank, and a perforated cylinder for installing a filter cartridge. Outside air is filtered through the filter before entering the tank, solving the problem of secondary contamination. The sealing mechanism replaces the traditional level gauge; when the water level rises, a float rises, causing a moving rod to move upwards. The sealing plug connects to the outer protrusion of the air inlet through a groove, thus sealing the air inlet. However, in practical use, this device cannot be easily installed and fixed in place, making it unsuitable for different models of direct drinking water machines. Furthermore, the smooth inner wall of the tank lacks antibacterial properties, allowing residual water stains to easily breed bacteria. Additionally, the flat-bottomed design of the tank easily creates stagnant water areas, and the complex flow channeling structure makes cleaning difficult. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a sterile direct drinking water tank with the advantages of stable installation, thorough antibacterial properties, and simple maintenance, thus solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sterile direct drinking water tank, comprising a tank body, a sealing cover installed on the top surface of the tank body, an annular airtight groove formed on the outer side of the sealing cover, a sealing rubber ring fixedly installed inside the annular airtight groove, a transparent water level groove formed on the front side of the tank body, a limit slider fixedly installed on the left side of the tank body, a handle installed on the outer side of the tank body, a water outlet installed on the bottom surface of the tank body, a silicone sealing sleeve installed on the outer side of the water outlet, and a one-way valve installed inside the water outlet.

[0008] Preferably, there are two of each of the annular airtight groove and the sealing ring, and an antibacterial pressure balancing valve is fixedly installed on the top surface of the sealing cover.

[0009] Through the above technical solutions, the annular airtight groove and sealing ring can increase the contact area between the sealing cover and the box, making the seal tighter and preventing external air, dust, microorganisms, etc. from entering the interior of the box, thereby maintaining the sterile environment of the equipment; while the antibacterial air pressure balance valve can automatically adjust the air pressure inside the box to keep it balanced with the external atmospheric pressure. This not only prevents the box from deforming or being damaged due to air pressure difference, but also filters the air entering the box, preventing external bacteria, dust and other pollutants from entering the interior of the box, thereby avoiding secondary pollution of the water inside.

[0010] Preferably, a UV-LED light strip is fitted into the inner top surface of the sealing cover, and a power supply line is electrically connected to the outer surface of the UV-LED light strip.

[0011] The above technical solution allows the UV-LED light strip to be powered via a power supply line. The UV-LED light strip emits ultraviolet light with a wavelength of 200-280nm. This wavelength of ultraviolet light has a strong bactericidal ability, which can effectively kill bacteria, viruses, fungi and other microorganisms in the water, prevent the growth and pollution of microorganisms in the tank, and ensure water quality safety. Furthermore, the UV-LED light strip and power supply line are simple and convenient to install, and can be flexibly designed and installed according to the shape and size of the tank.

[0012] Preferably, the inner side of the box is provided with a composite antibacterial film, which includes a silica base layer, a nano silver ion coating, and a photocatalytic coating.

[0013] Through the above technical solutions, the silica base layer can improve the mechanical strength of the tank, making it more robust and durable, able to withstand certain pressure and impact, and not easily damaged. Its smooth surface also makes it less prone to bacterial and dirt growth, facilitating cleaning and disinfection, and helping to maintain the cleanliness and hygiene of the tank interior. The nano-silver ion coating has a strong inhibitory and killing effect on dozens of pathogenic microorganisms such as Escherichia coli, Neisseria gonorrhoeae, and Chlamydia trachomatis, effectively preventing bacterial growth and reproduction inside the tank and achieving long-lasting antibacterial effects. The photocatalytic coating can prevent the growth of bacteria and mold, and decompose mold, germs, and other difficult-to-eliminate substances in the air, continuously purifying the air inside the tank and improving water quality and the usage environment.

[0014] Preferably, the inner bottom surface of the box is configured as an arc-shaped funnel, and the inner bottom surface of the box is provided with multiple guide grooves.

[0015] Through the above technical solutions, the arc-shaped funnel design can make the water flow smoother, reduce water flow resistance, ensure that all water in the tank is discharged, prevent water accumulation, and improve water output efficiency; while multiple guide channels can guide the water flow in a predetermined direction to avoid water flow turbulence, and also facilitate maintenance and cleaning.

[0016] Preferably, there are two limiting sliders, and the bottom of the box is provided with a fitting groove.

[0017] Through the above technical solutions, the limiting slider and the fitting slot can help the box achieve precise positioning during installation or use, ensuring that the box is in the correct and stable position, preventing displacement during operation, and enhancing the overall stability of the device.
