Description

Electrolyzed water generator

[technical field]

The present invention relates to an electrolyzed water generating device that discharges electrolyzed water using a manual pump. Electrolyzed water can be used for sterilization, sterilization, deodorization and other purposes.

[Background technique]

Currently, a technique for producing low-pH anodically electrolyzed water (acidic water) obtained by electrolyzing an aqueous electrolyte solution for use in sterilization or disinfection is known (JP-A-11-90442). Since the anode electrolyzed water generated on the anode side contains hypochlorous acid, the strong oxidation and chlorination of hypochlorous acid can be used for sterilization or disinfection, and this utilization method has been popularized in medical and other departments. Moreover, since the trace amount of ozone and dissolved oxygen contained in acidic water can promote the growth of granulation, it is also being studied as an auxiliary means of surgical treatment. In addition, cathode electrolyzed water is used for drinking.

As a device for producing electrolyzed water with this effect, PCT/JP95/01503 provides such a device for generating electrolyzed water, by means of a pump driven by a battery, the electrolytic solution is continuously pumped to the electrolyzer, and the continuous spray is electrolyzed to obtain of electrolyzed water. In this generating device, the drive is performed by a storage battery, which consumes a lot of power, has a short battery life, and is cumbersome to charge the battery.

In addition, there are also electrolyzed water generators that perform electrolysis in batches on the market. Because the generating device generates electrolyzed water in batches, electrolyzed water cannot be obtained immediately, and it takes about 10 minutes of electrolysis to prepare about 2 liters of cathode electrolyzed water and anode electrolyzed water. Since the generating device produces electrolyzed water once, each 2 liters of cathode electrolyzed water and anode electrolyzed water will be produced, so the amount is too large for personal use. In addition, the effect of electrolyzed water after long-term storage will decrease, so producing electrolyzed water exceeding the usage amount will cause a lot of waste.

There are also electrolyzed water generators that are directly connected to tap water pipes on the market. The device is bulky and expensive, and is not suitable for personal use. In addition, the generating device cannot be carried because it needs to be connected with a water pipe for use. Carrying and using the electrolyzed water produced by the generating device will cause the problem of deteriorating the water quality of the electrolyzed water.

[Detailed ways]

The present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a side view showing an example of an electrolyzed water generator 100 of the present invention.

In FIG. 1 , 2 is a substantially cylindrical container body with a hollow interior, and an electrolytic solution 4 is accommodated therein. The container body 2 has a shape in which the diameter becomes narrower as it goes upward, and a mouth 6 is formed at the upper end.

8 is a hollow electrolyzed water spray part, which is screwed to the mouth part 6 of the above-mentioned container main body 2 via the connection part 10 formed at the lower end.

In the above electrolyzed water spraying unit 8 , the nozzle unit 12 is provided such that the nozzle tip 14 protrudes outward from the electrolyzed water spraying unit 8 . The rear end 16 of the nozzle portion 12 is connected to one end 20 of the electrolyte solution supply channel 18 , and the other end 22 of the electrolyte solution supply channel 18 passes through the mouth 6 of the container body 2 and is inserted into the electrolyte solution 4 in the container body 2 .

24 is a check valve installed on the electrolyte solution supply channel 18 to prevent the electrolyte solution 4 from flowing back toward the container main body 2 in the electrolyte solution supply channel 18 .

Reference numeral 26 denotes a manual piston pump, which is provided between the nozzle portion 12 and the check valve 24 of the electrolytic solution supply passage 18 . The piston pump 26 transports the electrolyte solution 4 in the electrolyte solution supply channel 18 toward the nozzle portion 12 by reciprocating the piston 28 along its axial direction (Q direction indicated by the arrow). 30 is the spring that the piston 28 is bounced back.

32 is a discharge rod, which is installed on the electrolytic water spraying part 8 so as to be freely movable (in the RS direction indicated by the arrow) by means of a fitting shaft 34 . Therefore, by moving the rod 32 toward the container main body 2 (in the S direction of the arrow), the piston 28 of the pump 26 is pushed by the pressing protrusion 36 of the rod 32 to move. Accordingly, the electrolytic solution is sent toward the nozzle direction.

38 and 40 denote a pair of anode and cathode formed between the nozzle portion 12 of the electrolytic solution supply passage 18 and the piston pump 26 , respectively. The electrolytic solution flowing through the electrolytic solution supply passage 18 is electrolyzed by electric power supplied from the battery 42 as a power source. 44 is a control circuit, which controls the electrolysis current. 46 is a light emitting diode. The voltage of the battery is the best in practical application with 3.0 ~ 6.0V.

48 is a switch, and when the lever 32 is moved toward the container main body 2, the switch 48 moves in the direction of the arrow T and is in an "on" state. Thereby, electric power is supplied to the above-mentioned two electrodes 38, 40, and electrolysis of the electrolytic solution occurs.

Therefore, by driving the rod 32 , electrolysis of the electrolytic solution occurs, and the cathodic electrolyzed water generated by the electrolysis is sprayed outward from the tip 14 of the nozzle part 12 by the delivery force of the pump together with the anode electrolyzed water.

FIG. 2 is a structural diagram schematically showing the structure of the above example.

Fig. 3 shows another example of the present invention. In this example, a branch pipe 50 is connected to the electrolyte solution supply channel 18 in the container main body 2, and the branch pipe 50 is equipped with a constant pressure valve 52. The other structures are the same as those in FIG. 1, so the description thereof is omitted. Since the constant pressure valve 52 is installed, the electrolyzed water can be sprayed from the nozzle tip 14 in a discharge amount corresponding to the optimum electrolysis conditions. The operating pressure of the constant pressure valve can be determined through experimental tests to achieve the best electrolysis conditions.

In each of the above examples, a piston pump was used as the manual pump, but it is not limited to this, and various other pumps such as a diaphragm pump can also be used. In addition, a battery is used as the power source, but an AC power source having a transformer and a rectification circuit may also be used. In addition, the structure of a switch is not limited to this, and various other modifications are possible within the range which does not change the gist of this invention.

[Example]

An electrolyzed water generating device having the structure shown in Fig. 1 was fabricated. The inner volume of the container main body 2 is 300ml, which can accommodate 300ml of 0.05M salt water.

The electrodes are platinum plates with a size of 20mm×23.6mm×0.5mm and are installed on the electrolyte solution supply channel 18 at a distance of 0.18mm. The electrolysis current is controlled by the control circuit 44 to be 0.1A. The pump used was capable of discharging 0.5 ml every time the lever was operated.

In the electrolyzed water generating device of this embodiment, when the lever is pulled, the switch immediately enters the "on" state, the electrolyzed aqueous solution starts to be electrolyzed, and the generated electrolyzed water is sprayed from the top of the nozzle. When the rod is released after pulling the rod, under the action of the recovery spring not shown in the figure, the rod returns to its original position, and at the same time, the spraying of electrolyzed water stops, the switch enters the "off" state, and the electrolysis stops.

In the present invention, since the electrolytic solution is phase-shifted and sprayed manually, the structure of the device is simpler compared with the automatic spraying method using a motor. Therefore, the electrolyzed water generating device of the present invention can be manufactured at low cost. In particular, since the electrolytic solution is phase-shifted manually, when necessary, only the required amount of electrolyzed water can be sprayed immediately, and it is easy to carry. And it only consumes power during electrolysis, so the battery life can be extended. In addition, the electrolyzed water generating device of the present invention has the following advantages: the anode electrolyzed water and catholyte electrolyzed water produced by electrolysis can be discharged without separation, and the entire electrolyte solution can be used without draining.
