Description

Technical Field

[0001] The present invention relates to a household tap water treatment device, and in particular to a water treatment assembly with a disinfection and sterilization function, belonging to the technical field of household water use equipment. Background Art

[0002] In daily life, clean tap water is one of the essential living conditions for each family and enterprise. As a terminal device for obtaining domestic water in families, public places, etc., the sanitary condition of the water flowing out of the faucet directly affects people's health. Traditional faucets only have the function of controlling water flow. However, the urban tap water supply system has a long pipeline, and the tap water transported through the complex and long water conveyance pipeline of the water network may have sanitary hazards. Especially for high-rise buildings, water storage facilities for secondary water supply are also required. The water body may breed various bacteria, viruses and various harmful microorganisms in the water storage tank. Therefore, the water body discharged from the faucet may naturally carry a variety of bacteria, viruses and microorganisms.

[0003] As is well known, a biofilm is easily formed inside the faucet in long-term use, and various bacteria breed on the biofilm. These bacteria will flow out with the water flow, directly polluting people's daily domestic water and posing a potential threat to people's health. Although there are some products for water quality purification on the market at present, most of them filter impurities in the water body, usually using chemical sterilization. The chemical devices are usually installed at the front end of the tap water supply pipeline or in the water storage tank of the community, and are separate large devices. At present, the water outlet devices of families and enterprises do not fully have the function of disinfection and sterilization. Existing household water purifiers only have the function of impurity removal and filtration, and some are also equipped with the function of removing odors by stone and wood, but they do not fully have the function of killing bacteria, viruses and microorganisms in the water body.

[0004] People urgently need a device that can directly disinfect the water flow at the water use terminal. Summary of the Invention

[0005] The purpose of the present invention is to provide a household tap water pulsed intense light disinfection and sterilization device. As long as the water body flows through the effective irradiation coverage range of the pulsed intense light sterilization lamp, it can effectively disinfect and sterilize the water body, eliminate harmful microorganisms to the human body, ensure that every drop of water used by people is non-toxic and sterile, hygienic and safe, and it can eliminate the problem of water body germ pollution from the water use terminal.

[0006] The present invention adopts the following technical solutions: A household tap water pulsed intense light disinfection and sterilization device includes a water inlet joint, a water storage pipe body, a water outlet joint and a pulsed intense light sterilization lamp. The water inlet joint and the water outlet joint are both communicated with the inner cavity of the water storage pipe body. The pulsed intense light sterilization lamp is installed in the inner cavity of the water storage pipe body by a water insulation method and is located between the water inlet joint and the water outlet joint.

[0007] Further, the pulsed intense light sterilization lamp is a linear lamp tube, and the installation positions of the water inlet joint and the water outlet joint respectively correspond to both ends of the pulsed intense light sterilization lamp.

[0008] Further, the linear pulsed intense light sterilization lamp is coaxially and fixedly installed with the water storage pipe body.

[0009] Further, the water inlet joint and the water outlet joint are located on the same side of the water storage pipe body, that is, they are collinearly distributed at the same phase angle along the circumferential direction of the water storage pipe body.

[0010] Further, the water inlet joint and the water outlet joint are staggeredly distributed on the water storage pipe body, that is, they are staggeredly distributed along the circumferential direction of the water storage pipe body.

[0011] Further, the water inlet joint and the water outlet joint are respectively arranged at both ends of the water storage pipe body.

[0012] Further, the number of the linear pulsed intense light sterilization lamps is 1 to 10, and the axis of the linear pulsed intense light sterilization lamp is parallel to the axis of the water storage pipe body.

[0013] Furthermore, the number of the linear pulsed intense light sterilization lamps is 1, and the axis of the linear pulsed intense light sterilization lamp coincides with the axis of the water storage pipe body.

[0014] Further, the water storage pipe body is a disc-shaped body, and the pulsed intense light sterilization lamp is annular.

[0015] Further, a water flow homogenization structure is provided at the water inlet end of the water inlet joint, and a porous homogenization plate is provided between the bottom of the inner cavity of the water storage pipe body and the water inlet joint. The material of the porous homogenization plate is a copper-based catalyst alloy with a scale prevention function, and its components are eight metal elements of Cu, Ni, Zn, Sn, Pb, Fe, Sb, and Mn. The weight percentages of each component are: Cu 40% - 70%; Ni 5% - 20%; Zn 10% - 35%; Sn 5% - 30%; Pb 0.5% - 20%; Fe 0.1% - 8%; Sb 0.01% - 2%; Mn 0.05% - 5%. Each component is synthesized at high temperature into a columnar crystal alloy that grows directionally along the S 100 crystal axis. It can not only fragment and homogenize the water flow, prevent the aggregation of water bacteria groups from becoming too large and affecting the thoroughness of sterilization, but also effectively prevent the formation of water scale, dissolve water scale, ensure the stability and scale prevention performance of the secondary water supply system and the direct drinking water supply system, improve the service life of the present invention, and reduce the use and maintenance costs. The scale prevention function of this copper-based catalyst alloy material with a scale prevention function is described in detail in the authorized invention patent CN200810024432.0. The smaller the pore diameter and the greater the density on the porous homogenization plate, the better the homogenization effect.

[0016] Furthermore, the pulsed intense light sterilization lamp includes a linear lamp tube, lamp electrodes, end seals, and a support bracket. Lamp electrodes and end seals are respectively provided at both ends of the linear lamp tube. The end seals are used for water-tightly connecting the lamp electrodes, enabling the pulsed intense light sterilization lamp to have a waterproof function. The linear lamp tube is clamped on two spaced-apart support brackets.

[0017] Furthermore, the wavelength of the pulsed intense light sterilization lamp is 200nm - 1100nm.

[0018] Since the pulsed intense light sterilization lamp utilizes the high-intensity broadband pulsed light released instantaneously, including ultraviolet light, visible light, infrared light, etc., and acts on bacteria through various effects such as photothermal and photochemical effects. The light emitted by the pulsed intense light sterilization lamp is the full-spectrum light with a suitable wavelength of 200nm - 1100nm, which destroys the DNA or RNA structure of microorganisms, making them lose their viability. The inert gas xenon emits a strong flash under high voltage, and the photoelectric efficiency is as high as 95%. The energy generated by the ultraviolet light in the full spectrum is more than 3000 times that of traditional ultraviolet light, and the instantaneous intensity can reach the megawatt level, instantaneously generating high-energy visible light, ultraviolet light, and multiple electromagnetic wave polymerization effects. The pulsed intense light has high penetrability and can sterilize the interior of liquids. The sterilization efficiency is high, and the sterilization effect can reach more than 99.999%. It has low energy consumption and is 80% - 90% more energy-efficient than traditional ultraviolet lamps. It is flexible to control, that is, it can be turned on and off immediately. It does not use chemical reagents, and there is no pollution or residue.

[0019] Install the present invention at the water inlet end of domestic tap water. When the water at the water inlet end of the tap water flows into the inner cavity of the water storage pipe body from the water inlet joint, the whole process is under the irradiation of the pulsed intense light sterilization lamp. Bacteria, viruses, and microorganisms in the water body will be completely killed or decomposed under the irradiation of the pulsed intense light. If it is used in series with an existing water purifier, it can not only ensure the cleanliness of the water output but also disinfect and sterilize the water body. Connect the indoor water pipe system to the water outlet joint of the present invention, so as to ensure that the whole domestic water supply pipeline contains clean, non-toxic, and bacteria-free water. If the present invention is installed at the front end of the water outlet faucet, it can ensure that every drop of water released from the faucet is non-toxic, bacteria-free, hygienic, and safe, and can be directly drunk. Its effect is better than installing it at the indoor water inlet. It can ensure that the water released from the faucet is non-toxic, bacteria-free, hygienic, and safe, and it can eliminate the pollution problem of bacteria, germs, and harmful microorganisms in the water body at the water usage terminal.

[0024] The following combines the drawings to illustrate the specific embodiments of the present invention: Embodiment 1: A household tap water pulsed intense light disinfection and sterilization device, as Figure 1 shown, includes a water inlet joint 1, a water storage pipe body 2, a water outlet joint 3 and a pulsed intense light sterilization lamp 4. The pulsed intense light sterilization lamp 4 is a linear lamp tube. The water inlet joint 1 and the water outlet joint 3 are both communicated with the inner cavity of the water storage pipe body 2. The pulsed intense light sterilization lamp 4 is installed in the inner cavity of the water storage pipe body 2 by a water insulation method. The linear pulsed intense light sterilization lamp 4 is coaxially and fixedly installed with the water storage pipe body 2 and is located between the water inlet joint 1 and the water outlet joint 3. The installation positions of the water inlet joint 1 and the water outlet joint 3 respectively correspond to both ends of the pulsed intense light sterilization lamp 4. The water inlet joint 1 and the water outlet joint 3 are located on the same side of the water storage pipe body 2, that is, they are collinearly and spaced apart at the same phase angle along the circumference of the water storage pipe body 2. In this example, the emission wavelength of the pulsed intense light sterilization lamp 4 is 200nm - 1100nm. It includes a linear lamp tube 41, a lamp electrode 42, an end seal 43 and a support bracket 44. Lamp electrodes 42 and end seals 43 are respectively provided at both ends of the linear lamp tube 41. The end seal 43 makes a watertight connection to the lamp electrode 42, enabling the pulsed intense light sterilization lamp 4 to have a waterproof function. The linear lamp tube 41 is clamped on two spaced support brackets 44. This pulsed intense light sterilization lamp 4 is a commercially available product and belongs to the prior art, so its structure and working mechanism will not be introduced.

[0025] Embodiment 2: The difference from Embodiment 1 is that the water inlet joint 1 and the water outlet joint 3 are misaligned and distributed along the circumferential direction on the water storage pipe body 2, as Figure 3 shown.

[0026] Embodiment 3: The difference from Embodiment 1 is that the water inlet joint 1 and the water outlet joint 3 are respectively arranged on both sides of the water storage pipe body 2.

[0027] Embodiment 4: The difference from Embodiment 1 is that the number of linear pulsed intense light sterilization lamps 4 is 3. The three linear pulsed intense light sterilization lamps 4 are evenly distributed along the circumference on the same circle. The axes of all linear pulsed intense light sterilization lamps 4 are parallel to the axis of the water storage pipe body 2. The installation structure is the same as that of Embodiment 1, and they are all installed in the water storage pipe body 2 through the support brackets 44.

[0028] Example 5: The difference from Example 1 is that the water storage pipe body 2 is a disc-shaped body, the pulsed intense light sterilization lamp 4 is annular, and the water inlet joint and the water outlet joint are symmetrically distributed.

[0029] In the above embodiments, it is better to be provided with an impurity filter screen at the water inlet end of the water inlet joint 1 or be connected in series with a water purifier.

[0030] Usage method of the present invention: Installation steps: Turn off the water source, remove the original faucet, and clean the installation interface. Install the present invention at the water inlet end of the domestic water supply system or directly at the water inlet end of the original faucet, ensure that the water inlet joint is sealed and connected without water leakage, the faucet is sealed and connected to the water outlet joint, and connect the pulsed intense light sterilization lamp 4 to the power supply.

[0031] Usage and maintenance: Turn on the water source. When water is needed, open the faucet valve. The water flow passes through the sterilization module, and at the same time, the sterilization module automatically starts to work to sterilize the water flow. During daily use, regularly check the indicator light on the faucet. The present invention can effectively solve the sterilization problem at the terminal of domestic water use, has a broad market application prospect, and can provide a strong guarantee for people's healthy life.

[0032] Since the present invention adds a pulsed intense light sterilization lamp 4 in the water supply pipeline, the water flowing through the water supply pipeline is irradiated by the full spectrum with a wavelength of 200 - 1100 nm emitted by the pulsed intense light sterilization lamp 4 throughout the process, which can effectively destroy the DNA and RNA structures of bacteria, viruses and other microorganisms existing in the water, making them lose the ability to reproduce and survive. Due to the high energy density and broad-spectrum sterilization characteristics of the pulsed intense light, it can quickly kill various bacteria, viruses, algae and other microorganisms in the water, and the sterilization rate can reach more than 99.9%, thus achieving the sterilization purpose.

[0033] The structure of the present invention is simple. It can be directly installed at the water inlet end of domestic water supply or at the connection position of the faucet, without the need for large-scale transformation of the water supply pipeline, and the user's usage habits do not need to be changed. The operation is simple and convenient, and the sterilization process can be completed while using water.

[0034] It adopts the pulsed intense light sterilization and disinfection technology, without heating, low energy consumption, rapid and thorough sterilization. Compared with the traditional large-scale high-temperature sterilization equipment, the energy consumption is greatly reduced, reducing the user's usage cost.

[0035] There are many implementation manners of the present invention, and they will not be listed one by one here. As long as a pulsed intense light sterilization lamp 4 is set in the water supply pipeline and all the schemes for disinfecting and sterilizing the water body flowing through by the pulsed intense light sterilization lamp 4 belong to the protection scope of the present invention.
