Description

Technical Field

[0001] The present invention relates to the technical field of disinfection equipment, and particularly relates to a disinfectant solution manufacturing machine. Background Art

[0002] There is a rich variety of disinfectant solutions. Among them, sodium hypochlorite disinfectant solution is an efficient and safe disinfectant. The process of preparing sodium hypochlorite disinfectant solution is relatively simple and can be obtained by electrolyzing a mixed solution of tap water and table salt. Currently, there is a disinfectant solution manufacturing machine on the market, which includes an electrolysis chamber and a nozzle connected to the electrolysis chamber through a pipeline. A mixed solution of tap water and table salt is placed in the electrolysis chamber. After the electrodes in the electrolysis chamber are energized, the mixed solution of tap water and table salt is electrolyzed into sodium hypochlorite disinfectant solution, and the sodium hypochlorite disinfectant solution is atomized and sprayed out through the nozzle.

[0003] However, when the user operates improperly, or after the disinfectant solution manufacturing machine has not been used for a long time, the nozzle may become blocked, resulting in the entire machine being unable to work properly. Summary of the Invention

[0004] In view of this, the present invention provides a disinfectant solution manufacturing machine to solve the problem that table salt easily causes the nozzle to become blocked, resulting in the entire machine being unable to work properly.

[0005] The present invention provides a disinfectant solution manufacturing machine, including:

[0006] An electrolysis chamber, which is provided with an electrolysis module. The electrolysis chamber is adapted to hold a salt solution, and the electrolysis module can electrolyze the salt solution into sodium hypochlorite solution. The electrolysis chamber has a disinfectant solution outlet;

[0007] A nozzle, connected to the disinfectant solution outlet through a first pipeline assembly;

[0008] A cleaning liquid chamber, which is adapted to hold a cleaning liquid. The cleaning liquid chamber has a cleaning liquid outlet and a cleaning liquid return port. The cleaning liquid outlet is connected to the first pipeline assembly through a second pipeline, and the cleaning liquid return port is connected to the first pipeline assembly through a third pipeline. The cleaning liquid chamber, the second pipeline, at least part of the first pipeline assembly, and the third pipeline form a cleaning liquid circulation path;

[0009] A switch structure, having a first state in which the disinfectant solution outlet is communicated with the first pipeline assembly and a second state in which the cleaning liquid chamber is communicated with the first pipeline assembly.

[0010] Advantageous Effects:

[0011] When the disinfectant solution manufacturing machine is working normally, the electrolysis module electrolyzes the salt solution in the electrolysis chamber to generate sodium hypochlorite solution disinfectant. The disinfectant solution flows out from the disinfectant solution outlet, flows through the first pipeline assembly to the nozzle, and the nozzle atomizes and sprays the disinfectant solution for disinfection. When the disinfectant solution manufacturing machine is not used for a long time or the user adds too much salt, the salt will solidify and cause the nozzle to be blocked. At this time, the switch structure is switched to the second state, and the cleaning liquid chamber, the second pipeline, at least part of the first pipeline assembly, and the third pipeline form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline to the first pipeline assembly. Part of the cleaning liquid flows along the first pipeline assembly into the third pipeline and finally flows back to the cleaning liquid chamber for circulation. Another part of the cleaning liquid will flow to the nozzle to soak and melt the solidified salt in the nozzle. When the solidified salt in the nozzle is melted, the cleaning liquid flows out from the nozzle to complete the flushing of the nozzle, so that the disinfectant solution manufacturing machine can continue to work normally.

[0012] In an optional embodiment, the first pipeline assembly includes a first pipeline and a connector. The first end of the first pipeline is communicated with the disinfectant solution outlet. The connector has an inlet, a first outlet and a second outlet. The inlet is communicated with the second end of the first pipeline. The first outlet is connected to the nozzle, and the second outlet is connected to the third pipeline.

[0013] Beneficial effects:

[0014] By providing a connector, the first outlet of the connector is connected to the nozzle, and the second outlet of the connector is connected to the third pipeline. When the disinfectant solution manufacturing machine is working normally, the electrolysis module electrolyzes the salt solution in the electrolysis chamber to generate sodium hypochlorite solution disinfectant. The disinfectant solution flows out from the disinfectant solution outlet, flows through the first pipeline assembly to the connector, and then flows to the nozzle through the first outlet of the connector. The nozzle atomizes and sprays the disinfectant solution for disinfection. When the disinfectant solution manufacturing machine is not used for a long time or the user adds too much salt, the salt will solidify and cause the nozzle to be blocked. At this time, the switch structure is switched to the second state, and the cleaning liquid chamber, the second pipeline, the first pipeline, and the third pipeline form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline to the first pipeline. After the cleaning liquid flows to the connector, part of the cleaning liquid will flow out from the second outlet, pass through the third pipeline and finally flow back to the cleaning liquid chamber for circulation. Another part of the cleaning liquid will flow from the first outlet to the nozzle to soak and melt the solidified salt in the nozzle. When the solidified salt in the nozzle is melted, the cleaning liquid flows out from the nozzle to complete the flushing of the nozzle, so that the disinfectant solution manufacturing machine can continue to work normally.

[0015] In an alternative embodiment, the disinfectant solution manufacturing machine includes a control module. The first pipeline assembly further includes a water pressure sensor, which is disposed between the inlet of the connector and the first pipeline. The control module is communicatively connected to the water pressure sensor and the switch structure, and is capable of controlling the switch structure to switch to the second state when the pressure detected by the water pressure sensor exceeds a first preset value.

[0016] Advantageous effects:

[0017] When the nozzle is not blocked, the pressure detected by the water pressure sensor is within a range, usually 0.1 - 0.15 Mpa. When the nozzle is blocked, the pressure detected by the water pressure sensor will increase, for example, exceeding 0.25 Mpa. At this time, the control module controls the switch structure to switch to the second state, and the disinfectant solution in the electrolysis chamber will not continue to flow into the first pipeline. The cleaning liquid chamber, the second pipeline, the first pipeline, and the third pipeline form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline to the first pipeline. After the cleaning liquid flows to the connector, a part of the cleaning liquid will flow out from the second outlet, pass through the third pipeline and finally flow back to the cleaning liquid chamber for circulation, and another part of the cleaning liquid will flow from the first outlet to the nozzle to soak and melt the solidified salt in the nozzle. When the solidified salt in the nozzle is melted, the cleaning liquid flows out from the nozzle to complete the flushing of the nozzle, so that the disinfectant solution manufacturing machine can continue to work normally.

[0018] In an alternative embodiment, a switch valve is provided on the third pipeline.

[0019] Advantageous effects:

[0020] When the disinfectant solution manufacturing machine is not used for a long time or the user adds too much salt, the solidification of salt will cause the nozzle to be blocked. At this time, the switch structure is switched to the second state, and the switch valve on the third pipeline is opened; when the disinfectant solution manufacturing machine is working normally, the switch valve on the third pipeline is closed to prevent the disinfectant solution from entering the third pipeline.

[0021] In an alternative embodiment, the switch valve includes an electromagnetic pressure relief valve, which is in a normally closed state and can automatically open the third pipeline when the water pressure in the first pipeline exceeds the first preset value.

[0022] Advantageous effects:

[0023] Since the switching valve includes an electromagnetic pressure relief valve, when the nozzle is blocked, the water pressure will rise, and the electromagnetic pressure relief valve will automatically open the third pipeline. The control module controls the switching structure to switch to the second state, and the disinfectant solution in the electrolysis chamber will not continue to flow into the first pipeline. The cleaning liquid chamber, the second pipeline, the first pipeline, and the third pipeline form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline to the first pipeline. After the cleaning liquid flows to the connector, a part of the cleaning liquid will flow out from the second outlet, pass through the third pipeline and finally flow back to the cleaning liquid chamber for circulation. Another part of the cleaning liquid will flow from the first outlet to the nozzle to soak and melt the solidified salt in the nozzle. When the solidified salt in the nozzle is melted, the cleaning liquid flows out from the nozzle to complete the flushing of the nozzle, so that the disinfectant solution manufacturing machine can continue to work normally.

[0024] In an alternative embodiment, the switching valve is communicatively connected to the control module, and the control module is capable of controlling the switching valve to open when the pressure detected by the water pressure sensor exceeds a first preset value.

[0025] Beneficial effects:

[0026] The switching valve is communicatively connected to the control module, and the control module is capable of controlling the switching valve to open when the pressure detected by the water pressure sensor exceeds a first preset value.

[0027] When the nozzle is not blocked, the pressure detected by the water pressure sensor is within a range, usually 0.1 - 0.15 Mpa. When the nozzle is blocked, the pressure detected by the water pressure sensor will rise, for example, exceed 0.25 Mpa. At this time, the control module controls the switching structure to switch to the second state, controls the switching valve to open, and the disinfectant solution in the electrolysis chamber will not continue to flow into the first pipeline. The cleaning liquid chamber, the second pipeline, the first pipeline, and the third pipeline form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline to the first pipeline. After the cleaning liquid flows to the connector, a part of the cleaning liquid will flow out from the second outlet, pass through the third pipeline and finally flow back to the cleaning liquid chamber for circulation. Another part of the cleaning liquid will flow from the first outlet to the nozzle to soak and melt the solidified salt in the nozzle. When the solidified salt in the nozzle is melted, the cleaning liquid flows out from the nozzle to complete the flushing of the nozzle, so that the disinfectant solution manufacturing machine can continue to work normally.

[0028] In an alternative embodiment, a temperature control heating module is provided in the cleaning liquid chamber, and the temperature control heating module is communicatively connected to the control module. The control module is capable of:

[0029] Controlling the temperature control heating module to operate to heat the cleaning liquid in the cleaning liquid chamber to a preset temperature.

[0030] Beneficial effects:

[0031] By arranging a temperature control heating module in the cleaning liquid cavity, the cleaning liquid in the cleaning liquid cavity can be heated to a preset temperature, so that the solidified salt in the nozzle can be melted more quickly, and the flushing efficiency can be improved.

[0032] In an alternative embodiment, the first pipeline assembly further includes a water pump, the water pump is connected between the first pipeline and the disinfectant outlet, the water pump is communicatively connected with the control module, and the control module can control the water pump to stop working when the pressure detected by the water pressure sensor exceeds a first preset value, and control the water pump to work when the temperature control heating module heats the cleaning liquid in the cleaning liquid cavity to the preset temperature.

[0033] Beneficial effects:

[0034] By arranging a water pump, the operation of the water pump can provide power for the flow of the disinfectant in the electrolysis cavity to the nozzle, and can also provide power for the circulating flow of the cleaning liquid.

[0035] After the nozzle is blocked, the pressure detected by the water pressure sensor will rise, for example, exceed 0.25 Mpa. At this time, the control module controls the switch structure to switch to the second state and controls the water pump to stop working. At this time, neither the disinfectant nor the cleaning liquid will flow to the nozzle; when the temperature control heating module heats the cleaning liquid in the cleaning liquid cavity to the preset temperature, the control module controls the water pump to work. The cleaning liquid cavity, the second pipeline, the first pipeline, and the third pipeline form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline to the first pipeline. After the cleaning liquid flows to the connector, a part of the cleaning liquid will flow out from the second outlet, pass through the third pipeline and finally flow back to the cleaning liquid cavity for circulation, and another part of the cleaning liquid will flow from the first outlet to the nozzle. Since the temperature of the cleaning liquid is relatively high, the solidified salt in the nozzle can be quickly soaked and melted. When the solidified salt in the nozzle is melted, the cleaning liquid flows out from the nozzle to complete the flushing of the nozzle, so that the disinfectant manufacturing machine can continue to work normally. The cooperation of the water pump, the temperature control heating module, and the control module can further improve the flushing efficiency and avoid wasting the cleaning liquid.

[0036] In an alternative embodiment, a liquid level detection module is arranged in the cleaning liquid cavity, the liquid level detection module is communicatively connected with the control module, and the control module can:

[0037] When the liquid level detection module detects that the liquid level in the cleaning liquid cavity is lower than a first preset liquid level, send out an alarm signal;

[0038] When the liquid level detection module detects that the liquid level in the cleaning liquid cavity drops to a second preset liquid level, control the switch structure to switch to the first state;

[0039] When the liquid level detection module detects that the liquid level in the cleaning liquid chamber is not lower than the first preset liquid level, control the temperature control heating module to work to heat the cleaning liquid in the cleaning liquid chamber to the preset temperature.

[0040] Beneficial effects:

[0041] When the liquid level detection module detects that the liquid level in the cleaning liquid chamber is lower than the first preset liquid level, it indicates that the amount of cleaning liquid is insufficient, so an alarm signal is sent to remind the user to add cleaning liquid. During the process of flushing the nozzle, when the salt in the nozzle is not completely melted, the cleaning liquid flows from the second pipeline to the first pipeline. After the cleaning liquid flows to the connector, a part of the cleaning liquid will flow out from the second outlet, pass through the third pipeline and finally flow back to the cleaning liquid chamber for circulation, and another part of the cleaning liquid will flow from the first outlet to the nozzle to soak and melt the solidified salt in the nozzle. When the solidified salt in the nozzle is melted, the cleaning liquid flows out from the nozzle. At this time, the cleaning liquid in the cleaning liquid chamber will significantly decrease. When the liquid level in the cleaning liquid chamber drops to the second preset liquid level, it indicates that the flushing of the nozzle is completed. At this time, control the switch structure to switch to the first state, and the disinfectant in the electrolysis chamber can flow to the first pipeline and be atomized and sprayed out through the nozzle.

[0042] In an alternative embodiment, the nozzle is provided with an infrared sensor, and both the infrared sensor and the nozzle are communicatively connected to the control module. The control module can control the nozzle to work when the infrared sensor detects an infrared signal.

[0043] Beneficial effects:

[0044] By providing an infrared sensor at the nozzle, when the user needs to disinfect, they can stretch their hand under the nozzle. After the infrared sensor detects the infrared signal, it controls the nozzle to work, and the nozzle atomizes and sprays out the disinfectant. Therefore, automatic spraying of the disinfectant can be realized, which is more convenient for people to use and more intelligent.

[0045] In an alternative embodiment, the switch structure is a reversing valve. The first inlet of the reversing valve is connected to the disinfectant outlet, the second inlet of the reversing valve is connected to the second pipeline, and the outlet of the reversing valve is connected to the first pipeline assembly.

[0046] Beneficial effects:

[0047] The switch structure is a reversing valve, which has a simple structure and is convenient to control.

[0048] In an alternative embodiment, the disinfectant manufacturing machine includes a box body. A partition is provided inside the box body. One side of the partition forms the electrolysis chamber, and the other side of the partition forms the cleaning liquid chamber.

[0049] Beneficial effects:

[0050] The electrolysis chamber and the cleaning liquid chamber are of an integrated structure, with fewer components and a simple and compact structure.

[0051] In an alternative embodiment, the disinfectant solution manufacturing machine includes a housing, and the box body is disposed within the housing.

[0052] Advantageous effects:

[0053] By disposing the box body within the housing, the electrolysis chamber and the cleaning liquid chamber can be hidden within the housing, making the appearance more aesthetically pleasing.

[0054] In an alternative embodiment, a water receiving tray is provided at the bottom of the housing, and the water receiving tray is located below the nozzle.

[0055] Advantageous effects:

[0056] By providing a water receiving tray at the bottom of the housing, the excess disinfectant solution or cleaning liquid ejected from the nozzle can be collected, preventing corrosion of the housing.

[0057] The disinfectant solution manufacturing machine provided by the present invention:

[0058] When the disinfectant solution manufacturing machine is operating normally, the electrolysis module electrolyzes the salt solution in the electrolysis chamber to generate a sodium hypochlorite solution disinfectant. The disinfectant solution flows out from the disinfectant solution outlet, flows through the first pipeline assembly to the nozzle, and the nozzle atomizes and ejects the disinfectant solution for disinfection. When the disinfectant solution manufacturing machine is not used for a long time or when the user adds too much salt, the salt will solidify and cause the nozzle to become blocked. At this time, the switch structure is switched to the second state, and the switch valve on the third pipeline opens. The cleaning liquid chamber, the second pipeline, at least part of the first pipeline assembly, and the third pipeline form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline to the first pipeline assembly. Part of the cleaning liquid flows along the first pipeline assembly into the third pipeline and finally flows back to the cleaning liquid chamber for circulation, and the other part of the cleaning liquid will flow to the nozzle, soaking and melting the solidified salt in the nozzle. When the solidified salt in the nozzle is melted, the cleaning liquid flows out from the nozzle, completing the flushing of the nozzle, so that the disinfectant solution manufacturing machine can continue to operate normally.

[0066] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0067] There is a rich variety of disinfectant solutions. Among them, sodium hypochlorite disinfectant solution is an efficient and safe disinfectant. The process of preparing sodium hypochlorite disinfectant solution is relatively simple and can be obtained by electrolyzing a mixed solution of tap water and table salt. Currently, there is a disinfectant solution manufacturing machine on the market, which includes an electrolysis chamber and a nozzle connected to the electrolysis chamber through a pipeline. A mixed solution of tap water and table salt is placed in the electrolysis chamber. After the electrodes in the electrolysis chamber are energized, the mixed solution of tap water and table salt is electrolyzed into sodium hypochlorite disinfectant solution, and the sodium hypochlorite disinfectant solution is atomized and sprayed out through the nozzle.

[0068] Since the raw materials for preparing sodium hypochlorite disinfectant solution contain table salt, when the user adds too much table salt or the disinfectant solution manufacturing machine is not used for a long time, the table salt will solidify in the pipeline to form particulate matter, resulting in nozzle blockage and thus causing the entire machine to malfunction.

[0069] The related art discloses a disinfection device, including: a multi-way valve, the multi-way valve having a first valve inlet, a second valve inlet, and a valve outlet, the valve outlet selectively communicating with the first valve inlet or the second valve inlet, the first valve inlet for sucking in a disinfectant solution, and the second valve inlet for sucking in a cleaning solution; a water pump, the water pump communicating with the valve outlet, the water pump being configured to suck the disinfectant solution through the first valve inlet or the cleaning solution through the second valve inlet when operating. The water pump drives the multi-way valve to suck in the disinfectant solution through the first valve inlet and discharge it through the valve outlet for disinfection work, and then the water pump drives the multi-way valve to suck in the cleaning solution through the second valve inlet to clean the entire pipeline system of the disinfection device, preventing the disinfectant solution from remaining in the pipeline of the disinfection device, causing blockage of the pipeline of the disinfection device, and ensuring the normal use of the disinfection device.

[0070] When the disinfectant solution in the above related art is sodium hypochlorite disinfectant solution, when the nozzle is blocked by salt, during the process of flushing the pipeline with the cleaning solution, since the salt cannot melt immediately, it will cause unsmooth cleaning. Therefore, the above related art cannot solve the technical problem that the nozzle is blocked by salt, resulting in the entire machine being unable to work normally.

[0071] The following will be combined with Figures 1 to 4 , to describe the embodiments of the present invention.

[0072] According to an embodiment of the present invention, a disinfectant solution manufacturing machine is provided, including an electrolysis chamber 1, a nozzle 2, a cleaning solution chamber 3, and a switch structure 4.

[0073] An electrolysis module 5 is provided in the electrolysis chamber 1. The electrolysis chamber 1 is adapted to hold a salt solution. The electrolysis module 5 can electrolyze the salt solution into a sodium hypochlorite solution. The electrolysis chamber 1 has a disinfectant solution outlet 101; the nozzle 2 is connected to the disinfectant solution outlet 101 through a first pipeline assembly; the cleaning solution chamber 3 is adapted to hold a cleaning solution. The cleaning solution chamber 3 has a cleaning solution outlet 301 and a cleaning solution return port 302. The cleaning solution outlet 301 is connected to the first pipeline assembly through a second pipeline 8, and the cleaning solution return port 302 is connected to the first pipeline assembly through a third pipeline 9. The cleaning solution chamber 3, the second pipeline 8, at least part of the first pipeline assembly, and the third pipeline 9 form a cleaning solution circulation path; the switch structure 4 has a first state in which the disinfectant solution outlet 101 communicates with the first pipeline assembly and a second state in which the cleaning solution chamber 3 communicates with the first pipeline assembly.

[0074] In this embodiment, when the disinfectant solution manufacturing machine is working properly, the electrolysis module 5 electrolyzes the salt solution in the electrolysis chamber 1 to generate sodium hypochlorite solution disinfectant. The disinfectant solution flows out from the disinfectant solution outlet 101 and flows through the first pipeline assembly to the nozzle 2. The nozzle 2 atomizes and sprays the disinfectant solution for disinfection. When the disinfectant solution manufacturing machine is not used for a long time or the user adds too much salt, the salt will solidify and cause the nozzle 2 to be blocked. At this time, the switch structure 4 is switched to the second state, and the cleaning liquid chamber 3, the second pipeline 8, at least part of the first pipeline assembly, and the third pipeline 9 form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline 8 to the first pipeline assembly. Part of the cleaning liquid flows along the first pipeline assembly into the third pipeline 9 and finally flows back to the cleaning liquid chamber 3 for circulation. Another part of the cleaning liquid will flow to the nozzle 2 to soak and melt the solidified salt in the nozzle 2. When the solidified salt in the nozzle 2 is melted, the cleaning liquid flows out from the nozzle 2 to complete the flushing of the nozzle 2, so that the disinfectant solution manufacturing machine can continue to work properly.

[0075] It should be noted that the salt solution in the electrolysis chamber 1 can be formed by the user directly adding tap water and salt into the electrolysis chamber 1, or the user can configure the salt solution and then add it into the electrolysis chamber 1.

[0076] It should be noted that the cleaning liquid in the cleaning liquid chamber 3 can specifically be water.

[0077] In one embodiment, the first pipeline assembly includes a first pipeline 6 and a connector 7. The first end of the first pipeline 6 is communicated with the disinfectant solution outlet 101. The connector 7 has an inlet, a first outlet, and a second outlet. The inlet is communicated with the second end of the first pipeline 6. The first outlet is connected to the nozzle 2, and the second outlet is connected to the third pipeline 9.

[0078] In this embodiment, by providing a connector 7, the first outlet of the connector 7 is connected to the nozzle 2, and the second outlet of the connector 7 is connected to the third pipeline 9. When the disinfectant solution manufacturing machine is operating normally, the electrolysis module 5 electrolyzes the salt solution in the electrolysis chamber 1 to generate a sodium hypochlorite solution disinfectant. The disinfectant solution flows out from the disinfectant solution outlet 101, flows through the first pipeline assembly to the connector 7, and then flows through the first outlet of the connector 7 to the nozzle 2. The nozzle 2 atomizes and sprays the disinfectant solution for disinfection. When the disinfectant solution manufacturing machine is not used for a long time or when the user adds too much salt, the salt will solidify and cause the nozzle 2 to be blocked. At this time, the switch structure 4 is switched to the second state, and the cleaning liquid chamber 3, the second pipeline 8, the first pipeline 6, and the third pipeline 9 form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline 8 to the first pipeline 6. After the cleaning liquid flows to the connector 7, a part of the cleaning liquid will flow out from the second outlet, pass through the third pipeline 9 and finally flow back to the cleaning liquid chamber 3 for circulation, and another part of the cleaning liquid will flow from the first outlet to the nozzle 2 to soak and melt the solidified salt in the nozzle 2. When the solidified salt in the nozzle 2 is melted, the cleaning liquid flows out from the nozzle 2 to complete the flushing of the nozzle 2, so that the disinfectant solution manufacturing machine can continue to operate normally.

[0079] In one embodiment, the connector 7 is a three-way joint.

[0080] In one embodiment, the first pipeline assembly further includes a water pressure sensor 11 and a control module 12. The water pressure sensor 11 is disposed between the inlet of the connector 7 and the first pipeline 6. The control module 12 is communicatively connected to the water pressure sensor 11 and the switch structure 4, and is capable of controlling the switch structure 4 to switch to the second state when the pressure detected by the water pressure sensor 11 exceeds a first preset value.

[0081] In this embodiment, when the nozzle 2 is not blocked, the pressure detected by the water pressure sensor 11 is within a range, usually 0.1 - 0.15 Mpa. When the nozzle 2 is blocked, the pressure detected by the water pressure sensor 11 will rise, for example, exceed 0.25 Mpa. At this time, the control module 12 controls the switch structure 4 to switch to the second state, and the disinfectant solution in the electrolysis chamber 1 will not continue to flow into the first pipeline 6. The cleaning liquid chamber 3, the second pipeline 8, the first pipeline 6, and the third pipeline 9 form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline 8 to the first pipeline 6. After the cleaning liquid flows to the connector 7, a part of the cleaning liquid will flow out from the second outlet, pass through the third pipeline 9 and finally flow back to the cleaning liquid chamber 3 for circulation, and another part of the cleaning liquid will flow from the first outlet to the nozzle 2 to soak and melt the solidified salt in the nozzle 2. When the solidified salt in the nozzle 2 is melted, the cleaning liquid flows out from the nozzle 2 to complete the flushing of the nozzle 2, so that the disinfectant solution manufacturing machine can continue to operate normally.

[0082] In one embodiment, the third pipeline 9 is provided with a switch valve 10.

[0083] In this embodiment, when the disinfectant solution maker is not used for a long time or the user adds too much salt, the solidification of salt will cause the nozzle to be blocked. At this time, the switch structure 4 is switched to the second state, and the switching valve 10 on the third pipeline 9 is opened; when the disinfectant solution maker is working normally, the switching valve 10 on the third pipeline 9 is closed to prevent the disinfectant solution from entering the third pipeline 9.

[0084] In one embodiment, the switching valve 10 includes an electromagnetic pressure relief valve. The electromagnetic pressure relief valve is normally closed and can automatically open the third pipeline 9 when the water pressure in the first pipeline 6 exceeds a first preset value.

[0085] In this embodiment, since the switching valve 10 is an electromagnetic pressure relief valve, when the nozzle 2 is blocked, the water pressure will rise, and the electromagnetic pressure relief valve will automatically open. The control module 12 controls the switch structure 4 to switch to the second state, and the disinfectant solution in the electrolysis chamber 1 will not continue to flow into the first pipeline 6. The cleaning liquid chamber 3, the second pipeline 8, the first pipeline 6, and the third pipeline 9 form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline 8 to the first pipeline 6. After the cleaning liquid flows to the connector 7, a part of the cleaning liquid will flow out from the second outlet, pass through the third pipeline 9 and finally flow back to the cleaning liquid chamber 3 for circulation, and another part of the cleaning liquid will flow from the first outlet to the nozzle 2 to soak and melt the solidified salt in the nozzle 2. When the solidified salt in the nozzle 2 is melted, the cleaning liquid flows out from the nozzle 2 to complete the flushing of the nozzle 2, so that the disinfectant solution maker can continue to work normally.

[0086] In one embodiment, the switching valve 10 is communicatively connected to the control module 12, and the control module 12 can control the switching valve 10 to open when the pressure detected by the water pressure sensor 11 exceeds a first preset value.

[0087] In this embodiment, when the nozzle 2 is not blocked, the pressure detected by the water pressure sensor 11 is within a range, usually 0.1 - 0.15 Mpa. When the nozzle 2 is blocked, the pressure detected by the water pressure sensor 11 will rise, for example, exceed 0.25 Mpa. At this time, the control module 12 controls the switch structure 4 to switch to the second state, controls the switching valve 10 to open, and the disinfectant solution in the electrolysis chamber 1 will not continue to flow into the first pipeline 6. The cleaning liquid chamber 3, the second pipeline 8, the first pipeline 6, and the third pipeline 9 form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline 8 to the first pipeline 6. After the cleaning liquid flows to the connector 7, a part of the cleaning liquid will flow out from the second outlet, pass through the third pipeline 9 and finally flow back to the cleaning liquid chamber 3 for circulation, and another part of the cleaning liquid will flow from the first outlet to the nozzle 2 to soak and melt the solidified salt in the nozzle 2. When the solidified salt in the nozzle 2 is melted, the cleaning liquid flows out from the nozzle 2 to complete the flushing of the nozzle 2, so that the disinfectant solution maker can continue to work normally.

[0088] In one embodiment, a temperature control heating module 13 is provided in the cleaning liquid chamber 3. The temperature control heating module 13 is communicatively connected to the control module 12, and the control module 12 is capable of: controlling the temperature control heating module 13 to operate to heat the cleaning liquid in the cleaning liquid chamber 3 to a preset temperature.

[0089] In this embodiment, by providing the temperature control heating module 13 in the cleaning liquid chamber 3, the cleaning liquid in the cleaning liquid chamber 3 can be heated to a preset temperature, so that the solidified salt in the nozzle 2 can be melted more quickly, improving the flushing efficiency.

[0090] In one embodiment, the first pipeline assembly further includes a water pump 14, and the water pump 14 is connected between the first pipeline 6 and the disinfectant liquid outlet 101.

[0091] In this embodiment, by providing the water pump 14, the operation of the water pump 14 can provide power for the flow of the disinfectant liquid in the electrolysis chamber 1 to the nozzle 2, and can also provide power for the circulating flow of the cleaning liquid.

[0092] In one embodiment, the water pump 14 is communicatively connected to the control module 12. When the pressure detected by the water pressure sensor 11 exceeds a first preset value, the control module 12 can control the water pump 14 to stop working, and when the temperature control heating module 13 heats the cleaning liquid in the cleaning liquid chamber 3 to a preset temperature, the control module 12 can control the water pump 14 to work.

[0093] In this embodiment, when the nozzle 2 is blocked, the pressure detected by the water pressure sensor 11 will increase, for example, exceed 0.25 Mpa. At this time, the control module 12 controls the switch structure 4 to switch to the second state and controls the water pump 14 to stop working. At this time, neither the disinfectant liquid nor the cleaning liquid will flow to the nozzle 2; when the temperature control heating module 13 heats the cleaning liquid in the cleaning liquid chamber 3 to a preset temperature, the control module 12 controls the water pump 14 to work. The cleaning liquid chamber 3, the second pipeline 8, the first pipeline 6, and the third pipeline 9 form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline 8 to the first pipeline 6. When the cleaning liquid reaches the connector 7, a part of the cleaning liquid will flow out from the second outlet, pass through the third pipeline 9 and finally flow back to the cleaning liquid chamber 3 for circulation, and another part of the cleaning liquid will flow from the first outlet to the nozzle 2. Since the cleaning liquid has a higher temperature, it can quickly soak and melt the solidified salt in the nozzle 2. When the solidified salt in the nozzle 2 is melted, the cleaning liquid flows out from the nozzle 2 to complete the flushing of the nozzle 2, so that the disinfectant liquid manufacturing machine can continue to work normally. In this embodiment, the cooperation of the water pump 14, the temperature control heating module 13, and the control module 12 can further improve the flushing efficiency and avoid wasting the cleaning liquid.

[0094] In one embodiment, a liquid level detection module is provided in the cleaning liquid chamber 3. The liquid level detection module is communicatively connected to the control module 12, and the control module 12 is capable of:

[0095] When the liquid level detection module detects that the liquid level in the cleaning liquid chamber 3 is lower than the first preset liquid level, an alarm signal is issued.

[0096] When the liquid level detection module detects that the liquid level in the cleaning liquid chamber 3 drops to the second preset liquid level, the control switch structure 4 is switched to the first state.

[0097] When the liquid level detection module detects that the liquid level in the cleaning liquid chamber 3 is not lower than the first preset liquid level, the temperature control heating module 13 is controlled to work to heat the cleaning liquid in the cleaning liquid chamber 3 to the preset temperature.

[0098] In this embodiment, when the liquid level detection module detects that the liquid level in the cleaning liquid chamber 3 is lower than the first preset liquid level, it indicates that the amount of cleaning liquid is insufficient, so an alarm signal is issued to remind the user to add cleaning liquid. During the process of flushing the nozzle 2, when the salt in the nozzle 2 has not completely melted, the cleaning liquid flows from the second pipeline 8 to the first pipeline 6. After the cleaning liquid flows to the connector 7, a part of the cleaning liquid will flow out from the second outlet, pass through the third pipeline 9 and finally flow back to the cleaning liquid chamber 3 for circulation, and another part of the cleaning liquid will flow from the first outlet to the nozzle 2 to soak and melt the solidified salt in the nozzle 2. When the solidified salt in the nozzle 2 is melted, the cleaning liquid flows out from the nozzle 2. At this time, the cleaning liquid in the cleaning liquid chamber 3 will significantly decrease. When the liquid level in the cleaning liquid chamber 3 drops to the second preset liquid level, it indicates that the flushing of the nozzle 2 is completed. At this time, the control switch structure 4 is switched to the first state, and the disinfectant liquid in the electrolysis chamber 1 can flow to the first pipeline 6 and be atomized and sprayed out through the nozzle 2.

[0099] In an embodiment not shown in the figure, the temperature control heating module 13 may not be provided. When the pressure detected by the water pressure sensor 11 exceeds the first preset value, the water pump 14 still continues to work to gradually melt the solidified salt with the relatively low-temperature cleaning liquid.

[0100] In an embodiment, the nozzle 2 is provided with an infrared sensor. The infrared sensor and the nozzle 2 are both communicatively connected to the control module 12. The control module 12 can control the nozzle 2 to work when the infrared sensor detects an infrared signal.

[0101] In this embodiment, by providing an infrared sensor at the nozzle 2, when the user needs disinfection, the hand can be stretched under the nozzle 2. After the infrared sensor detects the infrared signal, the nozzle 2 is controlled to work, and the nozzle 2 atomizes and sprays out the disinfectant liquid. Therefore, automatic spraying of the disinfectant liquid can be realized, which is more convenient for people to use and more intelligent.

[0102] In an embodiment, the switch structure 4 is a reversing valve. The first inlet of the reversing valve is connected to the disinfectant liquid outlet 101, the second inlet of the reversing valve is connected to the second pipeline 8, and the outlet of the reversing valve is connected to the first pipeline assembly.

[0103] In this embodiment, the switch structure 4 is a reversing valve, which has a simple structure and is easy to control. Specifically, when the nozzle 2 is not blocked, the pressure detected by the water pressure sensor 11 is within a range, usually 0.1 - 0.15 Mpa. When the nozzle 2 is blocked, the pressure detected by the water pressure sensor 11 will rise, for example, exceeding 0.25 Mpa. At this time, the control module 12 controls the reversing valve to switch to the second state and controls the switch valve 10 to open. The disinfectant solution in the electrolysis chamber 1 will not continue to flow into the reversing valve. The cleaning liquid chamber 3, the second pipeline 8, the reversing valve, the first pipeline 6, and the third pipeline 9 form a cleaning liquid circulation path. The cleaning liquid flows from the second pipeline 8 to the first pipeline 6. After the cleaning liquid flows to the connector 7, a part of the cleaning liquid will flow out from the second outlet, pass through the third pipeline 9 and finally flow back to the cleaning liquid chamber 3 for circulation. Another part of the cleaning liquid will flow from the first outlet to the nozzle 2 to soak and melt the solidified salt in the nozzle 2. When the solidified salt in the nozzle 2 is melted, the cleaning liquid flows out from the nozzle 2 to complete the flushing of the nozzle 2, so that the disinfectant solution manufacturing machine can continue to work normally.

[0104] In an embodiment not shown in the figure, the switch structure 4 may include a first switch disposed on the first pipeline assembly and a second switch disposed on the second pipeline 8. When the first switch is open and the second switch is closed, the switch structure 4 is in the first state. When the first switch is closed and the second switch is open, the switch structure 4 is in the second state.

[0105] In an embodiment, the disinfectant solution manufacturing machine includes a box body 15. A partition 16 is provided inside the box body 15. One side of the partition 16 forms the electrolysis chamber 1, and the other side of the partition 16 forms the cleaning liquid chamber 3.

[0106] In this embodiment, the electrolysis chamber 1 and the cleaning liquid chamber 3 are of an integral structure, with fewer components and a simple and compact structure.

[0107] In an embodiment not shown in the figure, the disinfectant solution manufacturing machine includes a first water tank and a second water tank. The first water tank contains the electrolysis chamber 1, and the second water tank contains the cleaning liquid chamber 3.

[0108] In an embodiment, the disinfectant solution manufacturing machine includes a housing 17, and the box body 15 is disposed inside the housing 17.

[0109] In this embodiment, by disposing the box body 15 inside the housing 17, the electrolysis chamber 1 and the cleaning liquid chamber 3 can be hidden in the housing 17, making the appearance more beautiful.

[0110] Of course, in an embodiment not shown in the figure, the housing 17 may not be provided, and both the electrolysis chamber 1 and the cleaning liquid chamber 3 are exposed.

[0111] In an embodiment, a water receiving tray 18 is provided at the bottom of the housing 17, and the water receiving tray 18 is located below the nozzle 2.

[0112] In this embodiment, by providing a water receiving tray 18 at the bottom of the outer shell 17, the excess disinfectant or cleaning liquid ejected from the nozzle 2 can be received, preventing corrosion of the outer shell 17.

[0113] As shown in the figure, the control module 12 is connected to a power cord 19, and after the power cord 19 is powered on, it supplies power to the entire machine.

[0114] The disinfectant manufacturing machine provided in this embodiment works as follows:

[0115] When a blockage occurs, since a water pressure sensor 11 is arranged in front of the nozzle 2, after the blockage, the water pressure sensor 11 monitors that the system pressure will rise. The normal working pressure of the nozzle 2 is 0.1 - 0.15 Mpa. When the monitored pressure exceeds 0.25 Mpa, at this time, the control module 12 will control the water pump 14 to stop working, and the reversing valve switches to the second state. At this time, the cleaning liquid chamber 3 is communicated with the first pipeline 6, and the electromagnetic pressure relief valve opens.

[0116] The control module 12 controls the liquid level detection module and the temperature control heating module 13. The liquid level detection module detects whether the water level is lower than the first preset liquid level. If it is lower than the first preset water level, an alarm signal will be issued; if it is not lower than the first preset water level, the temperature control heating module 13 will be controlled to heat. After the temperature control heating module 13 detects that the temperature reaches 60 °C, it stops heating continuously. At the same time, the control module 12 controls the water pump 14 to work. Due to the 0.15 Mpa resistance of the electromagnetic pressure relief valve, when the nozzle 2 is in a blocked state, the 60 °C warm water in the cleaning liquid chamber 3 will flow through the nozzle 2, and the salt condensed in the nozzle 2 will dissolve faster. At the same time, it will return to the cleaning liquid chamber 3 through the electromagnetic pressure relief valve, thereby performing continuous flushing.

[0117] When the salt in the nozzle 2 dissolves, the nozzle 2 will resume normal spraying. Due to less resistance, most of the hot cleaning liquid will directly flow out from the nozzle 2, thereby gradually reducing the water level in the cleaning liquid chamber 3, and the dissolved salt will be discharged through spraying. When the water level drops to the second preset liquid level, the cleaning is completed. The reversing valve switches back to the first state, and the electromagnetic pressure relief valve closes.

[0118] Through the above embodiments, it is possible to avoid the failure of the entire machine caused by the blockage of the nozzle 2 due to the condensation of the raw material salt during preparation.

[0119] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
