Description

[Detailed Description of the Invention] <Industrial Field of Application> This invention relates to a faucet nozzle with a water purifier that is used by being attached to a water faucet, for example.

<Conventional technology> For example, in high-rise buildings such as condominiums, it is difficult to supply water to the upper floors of the building using only water pressure from the water supply, so generally a large water storage tank is installed on the roof of the building. Water from the city water supply is pumped up to this water storage pump using a pump, and then water is supplied to each floor from this water storage tank.

However, when such a water storage tank is used, the water tends to become dirty and unsanitary because bacteria and mold that have grown inside the tank, as well as iron rust and foreign objects that have entered the tank mix with the water and come out of the faucet. There is a drawback.

Therefore, each household usually attaches a simple filter member (for example, one made of synthetic resin with many open cells) to the water faucet. However, water cannot be purified to a satisfactory degree.

For this reason, it has recently become fashionable to use water purifiers that use high-performance filter materials such as coconut shell activated carbon, antibacterial activated carbon filters (silver activated carbon), or ultra-microporous hollow fiber membranes.

By using a water purifier like this, it is possible to remove bacteria, mold, and even chlorine and various organic substances from the water, making it possible to easily provide water of the same quality as mineral water to each household. be able to drink. This type of water purifier that has been used in the past is generally a stationary type that is connected to a water tap in each household with a hose or the like.

<Problems to be solved by the invention> By the way, the above-mentioned stationary type water purifier has the following problems:
When not in use, water always remains in the filter material at the bottom of the water purifier (in other words, residual water forms).

For this reason, if the water purifier is not used for a long period of time, bacteria will propagate at the bottom of the water purifier where water collects through the filter material, which can lead to unsanitary conditions. There is a problem in that drinking drinking water can cause illness due to bacteria.

In addition, in the case of conventional stationary water purifiers, it is necessary to separately install a switching member such as a kettle to switch the flow of water from the faucet to the water purifier side or the normal flowing water side, which is expensive. Another problem is that the switching process is troublesome.

The object of this invention is to provide a new faucet nozzle with a water purifier that does not have such problems.

<Means for solving the problem> The nozzle for a faucet with a water purifier of this invention has a water outlet at both ends that communicates with a connection port provided approximately in the center, and a filter material such as coconut shell activated carbon is built in on one side. a supporting member including a connecting port for connecting a rotating member to a water faucet, and a water hole communicating with the connecting port, the supporting member rotatably holding the rotating member at the connecting port; The gist is that the water passage hole of the support member is communicated with either one of the water flow ports of the rotating member depending on the rotational position.

In addition to coconut shell activated carbon, the above-mentioned filter materials include, for example, antibacterial activated carbon (silver activated carbon),
Calcium carbonate stone, ultra-fine pore hollow fiber membranes, polyolefin pleated membrane modules, and the like can be used alone or in appropriate combinations as necessary.

In addition, this faucet nozzle with a water purifier is usually used with its rotating member standing vertically in the axial direction (that is, the length direction), and for example, it rotates with the water passage hole provided in the support member. It is attached to a water faucet or the like so that it communicates with the water outlet located on the lower side of the member and forms a continuous waterway between them.

<Function> When using this nozzle for a faucet with a water purifier attached to a water faucet as described above, for example, when using this nozzle as a water purifier, rotate the rotating member at an appropriate angle to pass through the filter material. All you have to do is make sure that the water outlet on the side where the water flows is at the bottom.

In this state, water from the faucet is purified and flows through the water hole in the support member, the filter material in the rotating member, and the water outlet.

On the other hand, when not using it as a water purifier or when using water from the tap for washing dishes, etc., rotate the rotating member appropriately to prevent water from passing through the water outlet on the opposite side, that is, the filter material. It is best to make sure that the water outlet on the side is on the bottom side.

When not used as a water purifier like this, if you place the filter material and the water outlet on the side that does not pass water facing downward, the water accumulated in the filter material inside the rotating member will flow to the outside of the filter material. This allows the water to be naturally discharged and prevents water contamination due to bacterial growth etc. when not in use.

Moreover, in this faucet nozzle with a water purifier, switching between purified water using the filter material and normal flowing water can be easily performed by simply rotating the rotating member appropriately using the supporting member as the rotating shaft.

<Example> Examples of this invention will be described below.

As shown in FIGS. 1A and 1B, the nozzle for a faucet with a water purifier of this embodiment has a supporting member 1 and a rotating member 2.
It has the following.

Of these, the support member 1 is composed of a metal main body 12 and a cap 11, respectively. Main body 12
