The utility model provides a disinfectant liquid generating device.

In the embodiment of the present invention, as shown in fig. 1 to 7, the disinfecting liquid generating apparatus 10 includes a water tank 200, a water tank 300, a switch assembly 400, and an electrolysis module 500.

The water tank 300 is used for containing electrolyte containing chloride ions. For example, the water tank 300 is used to contain an aqueous solution of sodium chloride.

The switch assembly 400 is used to turn on or off the water tank 300 and the water tub 200. When the switch assembly 400 connects the water tank 300 and the water tank 200, the electrolyte in the water tank 300 can flow into the water tank 200; when the switching assembly 400 disconnects the water tank 300 from the water tank 200, the electrolyte in the water tank 300 cannot flow into the water tank 200.

The electrolysis module 500 is disposed in the water tank 200 and is used for electrolyzing an electrolyte containing chloride ions to generate a disinfectant containing hypochlorite ions.

In the related art, salt particles (sodium chloride) are put into a water tank of a disinfectant solution generator, a water tank supplies water into the water tank until a water level in the water tank and a water level in the water tank reach a balance (the water in the water tank and the water in the water tank are connected into a whole), and then an electrolysis module starts to electrolyze brine (sodium chloride aqueous solution) to generate a disinfectant solution (sodium hypochlorite aqueous solution). In the above disinfectant liquid generating apparatus, the water tank is in a communicating state with the water tank, so that after the disinfectant liquid (sodium hypochlorite solution) in the water tank is discharged, the water tank can also replenish water into the water tank, and the disinfectant liquid generating apparatus can continuously supply the disinfectant liquid. However, in practical applications, it is found that the sterilizing effect of the sterilizing liquid is increasingly poor in the process of continuously supplying the sterilizing liquid to the sterilizing liquid generating device. In addition, in practical applications, the service life of the electrolytic module is found to be low.

It is found that, in the above disinfectant generating device, since the water tank is used for containing the electrolyte containing chloride ions and the water tank are always in a communication state, the chloride ions in the water tank can diffuse into the water tank, and the chloride ions entering the water tank can enter the water tank again through a water replenishing manner to be electrolyzed by the electrolysis module. In order to ensure that all the chlorine ions are electrolyzed into hypochlorite ions, the electrolysis module is electrified for electrolysis, otherwise, the subsequent chlorine ions entering the water tank by a water replenishing mode cannot be ensured to complete the electrolysis. And the electrolytic module is operated all the time, which results in a reduction in service life. Before and after the water replenishment, the concentration of hypochlorite ions in the disinfectant decreases after the water replenishment because the concentration of hypochlorite ions is increased by electrolyzing the newly generated hypochlorite ions is much smaller than the concentration of hypochlorite ions decreased by the dilution. And along with the increase of the water replenishing times, the concentration of hypochlorite ions in the disinfectant is lower and lower, so that the sterilizing effect of the disinfectant is poorer and poorer.

When the disinfectant generating apparatus 10 is used to produce disinfectant, (a) the tank 300 and the water tank 200 may be first turned on by the switch assembly 400 to supply water to the water tank 200 through the water tank 300, and after the liquid level of the water tank 200 reaches a first predetermined liquid level, the water tank 300 and the water tank 200 may be turned off by the switch assembly 400. (B) Then, the water in the water tank 200 is electrolyzed by the electrolysis module 500 for a first predetermined time, and then the electrolysis is stopped to obtain the disinfectant containing hypochlorite ions. (C) After the disinfectant (sodium hypochlorite solution) in the water tank 200 is discharged or used for a preset amount, the liquid level of the water tank 200 is at a second preset liquid level; (D) the tank 300 and the water tank 200 are connected by the switch assembly 400 to replenish water to the water tank 200 through the water tank 300, and the water tank 300 and the water tank 200 are disconnected by the switch assembly 400 after the liquid level of the water tank 200 reaches a preset liquid level. The water in the water tank 200 is electrolyzed by the electrolysis module 500, and the electrolysis is stopped after a second predetermined time. Repeating the steps (C) and (D) until the electrolyte in the water tank 300 is almost used up.

It should be noted that the first preset liquid level and the second preset liquid level may be obtained through a liquid level scale located on the water tank 200, or may be obtained through a liquid level sensor. The first preset time and the second preset time can be obtained according to a plurality of tests or obtained according to experience.

In the above disinfectant generating apparatus 10, the water tank 300 contains the electrolyte containing chloride ions, and the switch assembly 400 is used to connect or disconnect the water tank 300 and the water tank 200, so that the electrolysis module 500 can electrolyze a preset amount of electrolyte (the liquid level of the water tank 200 reaches a preset liquid level) first and then stop the electrolysis in the process of producing the disinfectant. The electrolysis module 500 may stop the electrolysis, i.e., the electrolysis module 500 does not need to be operated all the time, so that the lifespan of the electrolysis module 500 may be extended. That is, the disinfection solution generator 10 can shorten the electrolysis time.

In the disinfectant generating apparatus 10, the water tank 300 contains the electrolyte containing chloride ions, and the water tank 300 and the water tank 200 are connected or disconnected by the switch unit 400, so that the concentration of hypochlorite ions in the disinfectant can be substantially uniform after water is supplied before and after water is supplied during the production of the disinfectant, and the disinfectant generating apparatus 10 can supply the disinfectant having a uniform sterilizing effect.

In this embodiment, the water tank 300 has a water outlet 302. The water tank 300 also has a material input port 304 that is separate from the water output port 302. Thus, solid sodium chloride and water can be respectively fed into the water tank 300 through the material feeding port 304, or a sodium chloride aqueous solution can be directly fed into the water tank 300 through the material feeding port 304. The independent water outlet 302 and the material input port 304 are arranged, so that the material can be more conveniently input. It is understood that in other embodiments, the material input port 304 may be omitted, and in this case, material may be input through the water output port 302.

In the present embodiment, the switch assembly 400 includes a blocking structure 400a and a driving structure 400 b.

As shown in fig. 5-7, the occluding structure 400a includes an occluding piece 410. The blocking piece 410 is arranged at the water outlet 302 and can block or open the water outlet 302.

The drive structure 400b includes a push rod 402. The push rod 402 has a first position and a second position, when the push rod 402 is in the first position, the blocking piece 410 blocks the water outlet 302, and when the push rod 402 is in the second position, the push rod 402 pushes the blocking piece 410 to open the water outlet 302, so that the blocking piece 410 opens the water outlet 302.

Meanwhile, the blocking piece 410 and the push rod 402 are arranged, so that the water outlet 302 can be better blocked and opened, and the water tank 300 and the water tank 200 can be connected or disconnected. It will be appreciated that in other embodiments, the push rod 402 may be omitted when the closure 410 itself is capable of switching between closing off the water outlet 302 and opening the water outlet 302.

In this embodiment, the plugging structure 400a further includes a plugging tube 420, a transmission member 430, an abutting member 440 and an elastic member 450. One end of the blocking tube 420 is disposed on the water tank 300 and surrounds the water outlet 302. A partition plate 422 is arranged in the plugging pipe 420, and a water outlet 4222 is arranged on the partition plate 422. The transmission member 430 is inserted into the water outlet 4222 and connected to the closing member 410. The abutting member 440 is located on a side of the partition 422 away from the blocking member 410, and is disposed on the transmission member 430. The elastic member 450 is sleeved on the transmission member 430, and two ends of the elastic member correspond to the partition 422 and the abutting member 440, respectively.

When the push rod 402 is in the first position, the push rod 402 is separated from the transmission member 430, and the blocking piece 410 blocks the water outlet 4222; when the pushing rod 402 is at the second position, the pushing rod 402 interferes with the transmission member 430, the blocking member 410 opens the water outlet 4222, and when the blocking member 410 opens the water outlet 4222, the elastic member 450 is compressed between the partition 422 and the abutting member 440.

Since the elastic member 450 is compressed between the partition 422 and the abutting member 440 when the blocking member 410 opens the drain opening 4222, the blocking member 410 can block the drain opening 4222 again by the restoring elastic force of the elastic member 450 when the push rod 402 is switched from the second position to the first position. In this way, it is very convenient to close and open the water discharge port 4222.

The water outlet 302 is indirectly blocked by the blocking piece 410 blocking the water outlet 4222, so that the blocking structure 400a and the water tank 300 are two independent components, and the production, the manufacture and the maintenance are more convenient. Specifically, in the present embodiment, the blocking tube 420 is detachably connected to the water tank 300. Thus, the plugging structure 400a and the water tank 300 are very convenient to disassemble and assemble. Specifically, in this embodiment, the outer wall of the water tank 300 is convexly provided with a water outlet pipe 310, and the water outlet 302 is located at the end of the water outlet pipe 310. The plugging pipe 420 is sleeved outside the water outlet pipe 310 and is in threaded connection with the water outlet pipe 310.

Specifically, as shown in fig. 8 and 9, the transmission member 430 is disposed on the water outlet 302, and one end of the transmission member is connected to the blocking member 410 inside the water tank 300, and the other end of the transmission member is connected to the abutting member 440 outside the water tank 300. The elastic member 450 is sleeved on the transmission member 430, and two ends of the elastic member correspond to the outer wall of the water tank 300 and the abutting member 440, respectively.

In this embodiment, when the push rod 402 is in the first position, the push rod 402 is separated from the transmission member 430, the blocking member 410 blocks the water outlet 4222, and the elastic member 450 is in a natural extension state.

In this embodiment, as shown in fig. 4-7, the sink 200 includes a bearing plate 210 and a mating seat 220. The mating seat 220 is disposed on the carrier plate 210.

The contact plate 442 is disposed on the transmission member 430 and can contact the elastic member 450. The sleeve 444 is sleeved outside the transmission member 430 and connected to the abutting plate 442. One end of the drain 222 near the carrier plate 210 is located within the sleeve 444. The end of the transmission member 430 remote from the block piece 410 is located in the drain pipe 220. The inner wall of the blocking tube 420 and the outer wall of the sleeve 444 form a first flow passage 460, the first flow passage 460 is communicated with the water outlet 4222, the inner wall of the sleeve 444 and the outer wall of the water discharge pipe 222 form a second flow passage 230, and the second flow passage 230 is communicated with the first flow passage 460 and the water inlet end 222 a. By forming the first flow passage 460 and the second flow passage 230, the liquid in the water tank 300 can be effectively prevented from contacting the liquid in the water tank 200.

In this embodiment, the water discharging pipe 222 includes a cylindrical section 2222 and a circular truncated cone section 2224 connected, and the cylindrical section 2222 is closer to the bearing plate 210 than the circular truncated cone section 2224. The end of the frustum section 2224 remote from the cylindrical section 2222 is a larger end. The end of the transmission member 430 remote from the blocking member 410 is inserted into the cylindrical section 2222.

The voltage regulating unit 910 and the current detecting unit 920 are disposed to control the operation of the electrolysis module 500 under a predetermined current condition.

In this embodiment, the constant current module 900 further includes a power supply 940. It is understood that in other embodiments, the power supply may be provided by an external power supply, and in this case, the power supply 940 may be omitted. Specifically, in the present embodiment, the power supply 940 is a constant voltage power supply.

It is understood that in other embodiments, the adjustment feedback unit 950 may also be integrated on the main control unit 930.

In this embodiment, as shown in fig. 11, a method for generating a disinfecting liquid is further provided, which includes the following steps:

step S110, a preset amount of water and a preset amount of solid sodium chloride are put into a water tank.

And step S120, waiting for T1 time to enable the solid sodium chloride to be completely dissolved, wherein T1 is 0-2 min. Specifically, in the present embodiment, T1 is 1 min.

Step S130, the water tank and the water tank are connected to supply water to the water tank through the water tank, so that the electrolyte containing chloride ions in the water tank flows into the water tank.

Step S140, acquiring a first actual liquid level of the water tank, determining that the first actual liquid level reaches a first preset liquid level, disconnecting the water tank from the water tank, and stopping water supply.

Step S150, after the electrolysis module in the water tank electrolyzes for a first preset time, the electrolysis is stopped to obtain the disinfectant in the first state.

And step S160, discharging the disinfectant in the water tank to obtain the disinfectant in the second state.

Step S170, acquiring a second actual liquid level of the water tank or acquiring a second voltage of the disinfectant in a second state, determining that the second actual liquid level of the water tank is smaller than a second preset liquid level or the second voltage is smaller than a preset voltage, and conducting the water tank and the water tank to replenish water to the water tank through the water tank.

It is understood that in other embodiments, when the water tank is directly filled with the sodium chloride aqueous solution, step S110 and step S120 may be omitted.

In this embodiment, the disinfectant in the water tank is discharged, in this embodiment, the disinfectant in the water tank is discharged by the water pump. The second preset liquid level is greater than or equal to the lowest effective drainage liquid level of the water pump. If the liquid level in the water tank is lower than the minimum effective drainage liquid level of the water pump, the water pump cannot effectively pump water, and the water tank needs to be replenished with water.

In this embodiment, it takes time to discharge the disinfecting liquid in the water tank. For example, when the disinfectant generating apparatus is applied to a humidifier, the demand of the humidifier for the disinfectant is relatively small after the disinfectant in the first state is obtained, so that the time for discharging the disinfectant in the water tank is long, and particularly, when the humidifier is stopped in use halfway, the time for discharging the disinfectant in the water tank is long. During the period of time for discharging the disinfecting liquid in the water tank, the water in the water tank volatilizes, so that the concentration of the conductive ions of the solution in the water tank is increased, namely the concentration of the conductive ions of the disinfecting liquid in the second state is increased, and the resistance is reduced. When the current is constant, the voltage is also reduced due to the reduction of the resistance. That is, a first voltage of the disinfecting liquid in the first state and a second voltage of the disinfecting liquid in the second state are obtained, and the second voltage is smaller than the first voltage. Therefore, whether water needs to be supplemented to the water tank through the water tank can be judged through the voltage.

In this embodiment, when the second voltage is less than the predetermined voltage, the water tank and the water tank are connected to replenish water to the water tank through the water tank. Wherein the preset voltage is less than the first voltage. Specifically, in the present embodiment, the preset voltage is 40% to 70% of the first voltage. Specifically, in the present embodiment, the preset voltage is 50% of the first voltage.

In this embodiment, the first predetermined liquid level is greater than the second predetermined liquid level, and in the direction of gravity, the first predetermined liquid level is located below the water outlet of the water tank, so that the liquid in the water tank cannot enter the water tank. Therefore, the liquid in the water tank can be effectively prevented from contacting with the liquid in the water tank.

In this example, the electrolysis was started by the electrolysis module simultaneously with the water supply step, and after the water supply was stopped, the electrolysis was stopped by the electrolysis module located in the water tank after T2 was electrolyzed. Wherein T2 is less than or equal to the first preset time, and T2 is 4-6 min. Specifically, in the present embodiment, T2 is 5 min.

The electrolysis is carried out while the water is supplied, so that the time can be saved, and the time of the whole disinfectant generating method is short. At this time, the first preset time is equal to T2. It is understood that in other embodiments, the electrolysis module may begin electrolysis again after the water supply step is completed. At this time, the first preset time is greater than T2.

In this embodiment, the first predetermined time and T2 are obtained through experiments, i.e. the time when the chloride ions in the water tank are substantially completely ionized.

In this embodiment, as shown in fig. 12, in the water replenishing process, the following steps are further included:

and step S172, acquiring a third actual liquid level of the water tank, determining that the third actual liquid level reaches a first preset liquid level, disconnecting the water tank from the water tank, and stopping water supplement.

And step S174, after the electrolysis module in the water tank electrolyzes for a second preset time, stopping electrolysis to obtain the disinfectant in a third state.

Step S176, acquiring a third actual liquid level of the water tank or acquiring a third voltage of the disinfectant in a third state, determining that the third actual liquid level of the water tank is less than the first preset liquid level or the third voltage is less than the preset voltage, and turning on the water tank and the water tank to replenish water to the water tank through the water tank.

In this example, the electrolysis module starts electrolysis while the water replenishing step is performed, and after the water replenishing is stopped, the electrolysis module located in the water tank electrolyzes T3 and stops the electrolysis. Wherein T3 is less than or equal to the second preset time, and T3 is 2-3 min. Because the water supplement amount is less than the first water supply amount of the water tank, the electrolysis time does not need to reach T2, namely T2 is more than T3.

The electrolysis is carried out while water is supplemented, so that the time can be saved, and the time of the whole disinfectant generating method is short. At this time, the second preset time is equal to T3. It is understood that in other embodiments, the electrolysis module may restart electrolysis after the water replenishing step is completed. At this time, the second preset time is greater than T3.

In this embodiment, the second predetermined time and T3 are obtained through experiments, i.e. the time when the chloride ions in the water tank are substantially completely ionized.

In this embodiment, the method for generating the disinfectant further includes the following steps:

and step S180, acquiring the actual storage liquid level of the water tank, determining that the actual storage liquid level is less than the preset storage liquid level, stopping electrolysis, and emptying the water tank and the water tank.

In this embodiment, the preset storage level is less than 20% of the actual storage level. At this point, the tank and sink may be emptied. And then repeats the above steps S110 to S170.

In this embodiment, the electrolysis module operates under a preset current condition.

In this embodiment, a humidifier is further provided, and the humidifier includes the disinfectant liquid generating device. The device can shorten the electrolysis time, ensure the consistency of hypochlorite ions in the disinfectant, and greatly shorten the sterilization time at 30m³In the cabinThe sterilization rate of white grape bacteria, escherichia coli and the like can reach 99.9% within 30min (the air output of the humidifier is the same). Compared with competitive products, the time is 1h, the sterilization time is reduced by 1 time, and the effect of killing bacteria at the fastest speed in the industry can be achieved.

The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
