Description

Tap and purifier that has it

Technical Field

The utility model relates to the technical field of water supply appliances, in particular to a faucet and a water purifier with the faucet.

Background

The faucet is used as a device for controlling the water outlet end of a waterway, and is widely applied to water using occasions such as kitchens, toilets and the like.

Conventional metal is generally used as the material of the existing faucet. For example, the material of the faucet body is usually copper, and the material of the outlet pipe is usually stainless steel. These metal materials are widely used because of their advantages of excellent bending strength, low price, easy molding, corrosion resistance, etc.

However, when the tap was subjected to a pure water soaking test, a large amount of substances were precipitated. Taking stainless steel as an example, since the nickel content in the stainless steel reaches 8%, after a pure water soaking experiment, the precipitation amount of nickel can exceed 0.002mg/L which meets the user safety. Therefore, the faucet made of metal material is seriously infringing the water safety of the user.

Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description merely illustrates a preferred embodiment of the utility model and that the utility model may be practiced without one or more of these details. In other instances, well known features have not been described in detail so as not to obscure the utility model.

In order to reduce precipitation of nickel and the like as much as possible and thus guarantee water safety of users, according to one aspect of the utility model, a faucet is provided. As shown in fig. 1-4, the faucet may include a faucet body 100 and a spout assembly 200. According to another aspect of the present invention, a water purifier is provided. The water purifier comprises any faucet of the embodiment of the utility model.

Faucet body 100 may take the form of various types of faucet bodies known in the art or that may come into existence in the future. The faucet body 100 may have an inlet 111 and an outlet 112. Illustratively, the faucet body 100 may include components such as a valve body, an operating handle 140, and the like. The valve body can be controlled to open and close by operating the handle 140, thereby controlling the on and off of the faucet body 100. When the main faucet body 100 is turned on, the water inlet 111 is communicated with the water outlet 112; when the main faucet body 100 is closed, the water inlet 111 and the water outlet 112 are closed.

The outlet tube assembly 200 may be connected to the faucet body 100 by any suitable means such as by a union joint, welding, bayonet, interference fit, etc. The outlet pipe assembly 200 includes, but is not limited to, a straight pipe, an elbow pipe, etc. The outlet pipe assembly 200 may include an outer pipe 210 and an inner pipe 220. The inner tube 220 may be inserted into the outer tube 210. The water inlet end 221 of the inner tube 220 may be connected to the water outlet 112 of the faucet body 100. In this way, the outer tube 210 can be isolated from the water path. In other words, the inside of the inner tube 220 may form the water passage 223. The water passage 223 may be communicated to the water inlet end 221 and the water outlet end 222 of the inner tube 220. No water flow path is formed between the outer tube 210 and the inner tube 220. The water may pass through the tap body 100 and the water passage 223 in order to flow out of the tap.

The material of the faucet body 100 and the inner tube 220 can be food grade material. The food-grade material generally comprises one or more of food-grade plastics, food-grade silica gel, and food-grade ceramics. In other words, the faucet body 100 or the inner tube 220 may be formed of the same food grade material, or a combination of different food grade materials. Food-grade plastics, food-grade silica gel and food-grade ceramics are commonly used, and the cost is low. Illustratively, food grade plastics include, but are not limited to, PE, PVC, POM, and the like. Preferably, the material of the tap body 100 may be food grade plastic or food grade silicone; the material of the inner tube 220 may be food grade plastic. Food grade materials are known to those skilled in the art and the improvements of the present invention are not in the materials themselves and will not be described in detail herein in order to avoid confusion. Because food grade material mechanical strength is usually not high, outer pipe 210 can carry out good support to inlayer pipe 220, effectively prevents that inlayer pipe 220 from being destroyed by external force. Thus, in a preferred embodiment, the inner tube 220 may be flexible. The outer tube 210 may be rigid. When water flows in the water passage 223, the flexible inner pipe 220 can effectively reduce the sound of water collision, thereby reducing the noise when the faucet is used. And, when the outer layer pipe 210 is a bent pipe, the inner layer pipe 220 may penetrate through the end of the outer layer pipe 210, thereby being inserted into the outer layer pipe 210. Thus, the shape of the outlet assembly 200 is more diversified. The rigid outer tube 210 may provide high mechanical strength to prevent the inner tube 220 from being damaged.

During use of the faucet, water can flow within the water passage 223. Thus, within the faucet, the components that the water directly contacts include the faucet body 100 and the inner tube 220. Because the faucet body 100 and the inner tube 220 are made of food-grade materials, substances such as nickel and the like cannot be separated out from the food-grade materials. Therefore, even after the experiment of soaking with pure water, the problem that nickel exceeds the standard can not occur, and the water safety of users is guaranteed. Therefore, the faucet is particularly suitable for being applied to a water purifier, so that the water quality of purified water filtered by the water purifier is guaranteed.

Preferably, as shown in FIGS. 4-6, the outlet 112 of the main faucet body 100 may be provided with a first connector 121. The first connector 121 may be any of various types of connectors known in the art or that may come into existence in the future, such as a quick connector. The water inlet end 221 of the inner tube 220 may extend out of the outer tube 210. The water inlet end 221 of the inner tube 220 may be connected to the first connector 121. At this time, the inner tube 220 is in communication with the water path of the faucet body 100. The material of the first joint 121 may be a food grade material. The first connector 121 may be the same or different material than the faucet body 100 or the inner tube 220. By arranging the first joint 121, the inner pipe 220 and the tap body 100 can be connected conveniently and the production efficiency is high. And, the first joint 121 can ensure the water safety of the user.

Further, as shown in fig. 4 to 6, a sealing ring 310 may be disposed between the first joint 121 and the inner pipe 220. By providing the sealing ring 310, the inner pipe 220 and the faucet body 100 are better sealed, and the probability of water leakage is greatly reduced.

Preferably, as shown in fig. 4 to 6, the inlet 111 of the tap body 110 may be provided with a second joint 122. The second connector 122 may be any type of connector known in the art or that may come into existence in the future, such as a quick connector. The first connector 121 and the second connector 122 may be the same or different. Illustratively, the faucet may also include an inlet tube (not shown). The inlet tube may be connected to the faucet body 100 by a second connector 122. The material of the second connector 122 may be a food grade material. The second connector 122 may be the same or different material than the faucet body 100 or the inner tube 220. Through the arrangement of the second joint 122, the connection between the water inlet pipe and the faucet main body 100 is convenient, and the production efficiency is high. And, the second joint 122 can ensure the water safety of the user. Illustratively, a sealing ring may be disposed between the second joint 122 and the inlet pipe.

Preferably, as shown in fig. 1-6, the outer tube 210 may have a first end. The first end is near the water inlet end 221 of the inner tube 220. The first end portion may have an elastic member 320 interposed between the faucet body 100. The resilient member 320 may maintain the position of the outer tube 210 relative to the faucet body 100. The first end of the outer pipe 210 is tightly coupled to the main faucet body 100 by the elasticity of the elastic member 320, thereby fixing the outer pipe 210. Moreover, if a water leakage occurs, the elastic member 320 can prevent water from flowing out between the outer pipe 210 and the main faucet body 100, which results in waste of water resources.

The number of the elastic members 320 may be arbitrary. Preferably, as shown in fig. 2 to 6, the number of the elastic members 320 may be plural. The plurality of elastic members 320 may be spaced apart along the extending direction of the outer tube 210. The distance directly spaced adjacent springs 320 may be the same or different. With this arrangement, the tightness between the first end portion of the outer pipe 210 and the faucet body 100 can be further enhanced.

Further, as shown in fig. 2 to 6, the outer sidewall of the first end portion of the outer tube 210 may be provided with a necking 211. The elastic member 320 may be fitted over the throat 211. The throats 211 may correspond one-to-one to the elastic members 320. The throat 211 may secure the resilient member 320, thereby preventing the resilient member 320 from being dislodged from its intended position, and ensuring a tight connection between the first end of the outer tube 210 and the main faucet body 100.

Preferably, as shown in FIGS. 4-6, the main faucet body 100 may be provided with a plug hole 130. The outlet 112 of the main faucet body 100 may be disposed within the plug aperture 130. The first end of the outer tube 210 may be inserted into the insertion hole 130. The elastic member 320 may be fitted over the outer tube 210. The elastic member 320 may be clamped between an outer sidewall of the outer tube 210 and an inner sidewall of the insertion hole 130. The insertion holes 130 may serve as a positioning so that the outer tube 210 can be easily installed to a predetermined position thereof, thereby allowing easy installation.

Preferably, as shown in fig. 1-5, the outer tube 210 may have a second end. The second end is proximate the water outlet end 222 of the inner tube 220. The second end may have an inner diameter 212 that decreases in the direction of the water outlet. The inner diameter 212 may provide an interference fit of the second end with the inner tube 220. With this arrangement, the second end of the outer tube 210 can be securely fixed to the water outlet end 222 of the inner tube 220. When the inner pipe 220 is installed, the inner diameter 212 can play a limiting role, so that the installation position of the inner pipe 220 can be accurate, and the good batch consistency of the faucet is ensured. In addition, the inner diameter 212 can prevent foreign matters such as dust from entering the gap between the outer pipe 210 and the inner pipe 220, thereby ensuring that the faucet is more sanitary.
