Background technique

With the rapid development of my country's economy, people's requirements for drinking water are getting higher and higher. Ultraviolet sterilization is a mature sterilization solution in the water treatment industry. Its principle is to use ultraviolet rays within a certain wavelength range to destroy the genetic material of microorganisms to kill microorganisms. Traditional UV mercury lamps have shortcomings such as short lifespan, low sterilization efficiency, and high toxicity, and are gradually being phased out by the market. Mercury and other advantages have been widely used in the water purification industry to assist the filtration units of water purifiers, such as micro-filters, ultra-filters and reverse osmosis membrane filters, to solve the problem of bacterial contamination of household drinking water.

The sterilization effect can only be achieved when a certain dose of ultraviolet radiation is reached. Existing water purifiers are often equipped with an ultraviolet sterilization module at the bottom of the faucet. Although it can perform over-flow sterilization, due to the absorption of ultraviolet light by the water pipe at the end of the faucet, the irradiation dose of ultraviolet light in the water pipe cannot reach the sterilization effect. effect. During the long-term use of the water purifier, the inside of the faucet is polluted by the external environment, which is easy to breed bacteria.

Detailed ways

This embodiment first provides a faucet, which can not only sterilize the purified water, but also sterilize the whole space inside the faucet to fully ensure the health of drinking water. FIG. 1 is a schematic diagram of a connection structure of a faucet 100 and a water purifier 200 according to an embodiment of the present invention. As shown in FIG. 1 , the faucet 100 of this embodiment may generally include: a light source module 110 and an end pipe 120 .

Wherein, the interior of the light source module 110 may be provided with a sterilizing light source, which is configured to sterilize the purified water. In a specific embodiment, the germicidal light source may be an ultraviolet germicidal lamp, and the light-emitting angle thereof is a preset angle. More specifically, the germicidal light source may be a UV device having a germicidal effect with different wavelengths such as deep UV LED and UV light emitting diode. Spectral applications of deep UV LEDs are increasing because they can solve technical problems in miniaturization, cost reduction and real-time measurement, and can be widely used in water sterilization, air sterilization, surface sterilization, and biomedicine. The wavelength range of deep ultraviolet LEDs is generally around 260nm, 275nm and 280nm. In some other embodiments, the germicidal light source may also be other light sources with germicidal effect other than the ultraviolet germicidal lamp.

One end of the end pipeline 120 is connected to the light source module 110 , and the other end is a water outlet 121 for the sterilized water to flow out. In addition, the end pipeline 120 may include: a reflective layer 122 and a protective layer 123, wherein the protective layer 123 is disposed outside the reflective layer 122, and the light emitted by the sterilization light source is reflected in the reflective layer 122 to sterilize the interior of the end pipeline 120.

The light source module 110 cooperates with the reflective layer 122 to complete the sterilization process. In order to achieve the optimal sterilization effect, on the premise of ensuring the water flow, the sterilization light source and the end pipeline 120 can be made coaxial, and the distance between the sterilization light source and the lower end of the end pipeline 120 The closer the better. The germicidal light source is coaxial with the end pipe 120, but as mentioned above, the germicidal light source can be an ultraviolet germicidal lamp, and its emitting angle is a preset angle, so the emitted light can reach the inner wall of the end pipe 120, that is, reflect light layer 122 , so that reflection occurs in the reflective layer 122 . In the faucet 100 of this embodiment, the light emitted by the sterilizing light source can not only sterilize the purified water in the end pipeline 120, but also reflect on the reflective layer, thereby sterilizing the whole space inside the faucet 100, and fully ensuring the health of drinking water .

Specifically, the case where the light emitted by the germicidal light source is reflected on the reflective layer 122 may include: diffuse reflection, specular reflection and total reflection. In this embodiment, the reflective layer 122 may be made of a material with a condition of total reflection, and the light emitted by the sterilization light source is totally reflected on the reflective layer 122 . Total reflection refers to the phenomenon in which all light is reflected back into the original medium when it is emitted from the optically denser medium to the interface of the optically sparser medium. The optically dense medium means that the refractive index of light in this medium is large, and the optically sparse medium means that the refractive index of light in this medium is small. Therefore, the protective layer 123 in this embodiment is an optically sparser medium relative to the reflective layer 122. It should be emphasized that, in this case, in order to ensure the reflectivity of total reflection, the protective layer 123 and the reflective layer 122 need to have a preset value between them. There is an air layer 125 between the protective layer 123 and the light-reflecting layer 122 in the gap of the distance.

In a preferred embodiment, the reflective layer may be a quartz glass material or a COC (CYCLOALKENE copolymer, cyclic olefin copolymer) material. COC is an amorphous and transparent copolymer polymer object having a cyclic olefin structure. It has optical properties comparable to polymethyl methacrylate and acrylic resin, and has higher heat resistance than polycarbonate, and also has more excellent dimensional stability and the like due to low water absorption. Furthermore, it is possible to improve water vapor airtightness, increase rigidity, heat resistance, and provide advantages such as ease of cutting. As a high-quality and high-purity amorphous cyclic resin, it can replace quartz glass with excellent properties and cost-effectiveness.

The inner wall of the protective layer 123 may be provided with reinforcing ribs 124 to fix and protect the reflective layer 122 . As shown in FIG. 1 , the reinforcing rib 124 may be disposed at a position close to the water outlet 121 and a position close to the lower end of the terminal pipe 120 . In a specific embodiment, the reinforcing ribs 124 can be a certain number of small flanges, and the protective layer 123 can fix and protect the reflective layer 122 to prevent it from being broken. When the germicidal light source is an ultraviolet germicidal lamp, the protective layer 123 can also absorb a small amount of ultraviolet light leaked from the reflective layer 122 to prevent the user from directly contacting the reflective layer 122 and causing harm to the human body.

FIG. 2 is a schematic diagram of the connection structure of the faucet 100 and the water purifier 200 according to another embodiment of the present invention. The reflection layer 122 of the faucet 100 in this embodiment is diffuse reflection or specular reflection. Specifically, the reflective layer 122 may be a material with diffuse reflection conditions, and the light emitted by the germicidal light source is diffusely reflected on the reflective layer 122 . Alternatively, the reflective layer 122 may be a material with specular reflection conditions, and the light emitted by the germicidal light source is specularly reflected on the reflective layer 122 .

In both cases of diffuse reflection and specular reflection, the protective layer 123 and the reflective layer 122 may be in direct contact. As shown in FIG. 2 , the reflective layer can be regarded as the inner wall of the protective layer 123 . In a specific embodiment, the light emitted by the germicidal light source is diffusely reflected on the reflective layer 122, and the reflective layer 122 may be polytetrafluoroethylene. In another specific embodiment, the light emitted by the germicidal light source is specularly reflected on the reflective layer 122, and the reflective layer 122 may be an aluminum film. The protective layer 123 in the above embodiments can all be made of stainless steel. That is to say, the protective layer 123 can be a stainless steel tube, and an aluminum film is arranged on the inner wall of the stainless steel tube as the reflective layer 122 , so that the light emitted by the sterilization light source is mirror-reflected on the reflective layer 122 .

In a preferred embodiment, the inner wall or the outer wall of the reflective layer 122 may be coated with a fluorescent material, so that the reflective layer 122 displays a fluorescent color when the ultraviolet light emitted by the germicidal light source arrives. Therefore, the invisible ultraviolet light can be converted into visible light, that is, the user can intuitively see the process of sterilizing the interior of the terminal pipeline 120 through the displayed fluorescent color.

The fluorescent material may be a fluorescent powder, a fluorescent film, or the like. In a specific embodiment, the fluorescent material may be an ultraviolet photoluminescent pigment. This kind of fluorescent pigment is composed of metal sulfide or rare earth oxide and trace active agent, and is calcined. Under the visible light source, it is white or nearly transparent. Under the irradiation of ultraviolet light of 200-400 nm, it shows different fluorescent colors according to the type and content of metals and activators in the pigment.

It should be noted that, when the protective layer 123 is a transparent material, the user can directly check the sterilization situation through the entire terminal pipeline 120 . In the case where the protective layer 123 is made of opaque materials such as stainless steel, only the reflective layer 122 can be provided at the water outlet 121 without the protective layer 123, that is, the protective layer 123 at the water outlet 121 can be slightly shorter to avoid the reflective layer 122, so that the The fluorescent color displayed by the reflective layer 122 is seen by the user. Alternatively, the reinforcing rib 124 at the water outlet 121 can also be set to be a transparent material, and the fluorescent color displayed by the reflective layer 122 can be seen by the user through this.

The faucet 100 of this embodiment can not only sterilize the purified water, but also sterilize the entire space inside the faucet 100 to fully ensure the health of drinking water; the entire sterilization process can be visualized to improve the user experience, and can effectively prevent ultraviolet rays leakage to prevent injury to the user.

This embodiment also provides a water purifier. As shown in FIG. 1 and FIG. 2 , the water purifier 200 may include: a main body 210 and a water purification pipeline 220 . Wherein, the body 210 may be configured to purify tap water. The body 210 may be provided with a filter unit, such as a micro filter element, an ultra-filter element, a reverse osmosis membrane filter element, etc., to purify the tap water. One end of the water purification pipeline 220 is connected to the body 210, and the other end can be connected to the faucet 100 of any of the above embodiments.

That is to say, the tap water is first purified by the body 210 of the water purifier 200, then enters the faucet 100 through the water purification pipeline 220, passes through the light source module 110 and the end pipeline 120 in sequence, and is sterilized by the sterilizing light source in the light source module 110 during the flow process. The emitted light is sterilized, and finally the purified and sterilized high-quality drinking water flows out from the water outlet 121 . 1 and 2 , the light source module 110 may further include a mounting portion 112 , the sterilizing light source is disposed inside the mounting portion 112 , and the water purification pipeline 220 and the end pipeline 120 are also connected to the mounting portion 112 respectively. It should be noted that the water does not contact the sterilization light source during the process of flowing through the light source module 110 , that is, the sterilization light source is completely isolated from the water, so as to avoid affecting the normal operation of the sterilization light source and effectively ensure safe use.

In addition, the sterilization process of the faucet 100 can have the following control methods, that is, the opening and closing of the sterilization light source can be controlled according to the following methods. The sterilization light source is turned on at regular intervals for sterilization, and the sterilization light source is turned off after a preset period of time. Alternatively, when the total purified water volume reaches the preset water volume, the sterilization light source is turned on for sterilization, and the sterilization light source is turned off after a preset time period. Or, when it is detected that the number of bacteria in the end pipe 120 of the faucet 100 is the first preset value, the sterilization light source is turned on for sterilization, and when it is detected that the number of bacteria in the end pipe 120 of the faucet 100 is the second preset value When the value is set, the sterilization light source is turned off, wherein the second preset value is smaller than the first preset value.

By now, those skilled in the art will recognize that, although various exemplary embodiments of the present invention have been illustrated and described in detail herein, the present invention may still be implemented in accordance with the present disclosure without departing from the spirit and scope of the present invention. The content directly determines or derives many other variations or modifications consistent with the principles of the invention.
