Description

Technical Field

[0001] This invention relates to the field of hypochlorous acid disinfectant preparation technology, specifically a modular and digital hypochlorous acid disinfectant generator. Background Technology

[0002] An existing method for preparing hypochlorous acid disinfectant involves delivering the stock solution, water, and carbon dioxide to a gas-liquid mixing module via an injection pump, water pump, and gas pump. The stock solution, water, and carbon dioxide are mixed in the gas-liquid mixing module to prepare hypochlorous acid disinfectant, which is then delivered to a hypochlorous acid storage tank via an infusion tube. This method involves numerous pipelines and the installation of components such as solenoid valves and sensors. The pipelines are intertwined and scattered, and the installation and maintenance of components occupy a large space, making installation and maintenance inconvenient. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a modular and digital hypochlorous acid disinfectant generator that is simple in structure, fully automated in production, easy to install and maintain, and modularly assembled.

[0004] The technical solution adopted by this invention to solve its technical problem is: A modular and digital hypochlorous acid disinfectant generator is characterized by comprising a generator housing, a liquid storage module, a water supply module, a gas supply module, a raw liquid pump and valve integrated module, an inlet and outlet liquid measurement and control module, and a gas-liquid mixing control module. The raw liquid pump and valve integrated module, the inlet and outlet liquid measurement and control module, and the gas-liquid mixing control module are located inside the generator housing, while the water supply module, the gas supply module, and the liquid storage module are located inside or outside the generator housing. The gas-liquid mixing control module is equipped with a water inlet, an air inlet, a liquid inlet, and a mixed liquid outlet. The water supply module is connected to the water inlet of the gas-liquid mixing control module via the liquid inlet / outlet measurement and control module to supply water to the gas-liquid mixing control module. The air supply module is connected to the air inlet of the gas-liquid mixing control module via the liquid inlet / outlet measurement and control module to supply air to the gas-liquid mixing control module. The liquid storage module is connected to the liquid inlet of the gas-liquid mixing control module via the raw liquid pump valve integration module to supply raw liquid to the gas-liquid mixing control module. The mixed liquid outlet of the gas-liquid mixing control module is connected to an external liquid storage tank via the liquid inlet / outlet measurement and control module. The various modules for preparing hypochlorous acid disinfectant are integrated, which facilitates installation, inspection, maintenance and replacement, and also facilitates assembly on the production line.

[0005] The liquid storage module of the present invention includes a liquid storage tank and a raw liquid tank. The raw liquid tank includes a tank body and a liquid outlet. A sealing film is affixed to the liquid outlet to seal the raw liquid in the tank. The top of the storage tank is provided with a raw liquid tank connecting sleeve, which is connected to the inside of the storage tank. The raw liquid tank connecting sleeve is provided with a membrane opening component. The inverted liquid outlet of the raw liquid tank is inserted into the raw liquid tank connecting sleeve. The sealing membrane is inserted through the membrane opening component, and the raw liquid in the raw liquid tank flows out through the liquid outlet into the storage tank. The storage tank is also provided with a raw liquid outlet hole, and the raw liquid in the storage tank enters the raw liquid pump valve integrated module through the raw liquid outlet hole. The liquid storage tank is equipped with a built-in liquid level sensor inside and / or an external liquid level sensor outside the liquid storage tank. It is easy to operate. Simply invert the sealed concentrate container onto the storage tank to achieve automatic filling without manual filling. This effectively prevents liquid leakage during filling, ensures the sealing of the filling, and reduces contamination of the concentrate. The sensor is set to detect the concentrate level in the storage tank. When the built-in liquid level sensor and the external liquid level sensor are used simultaneously, the accuracy and reliability of the measurement are further guaranteed.

[0006] The present invention has an electronic tag fixed on the stock solution tank and a card reader provided on or inside the generator housing. The electronic tag reads data through the card reader. By setting the electronic tag and the card reader to work together, the card reader can read the information of the stock solution tank and feed it back to the controller. The controller identifies whether it is a dedicated stock solution tank, ensuring that the stock solution used meets the requirements and that the concentration and quality of the prepared hypochlorous acid disinfectant solution meet the requirements.

[0007] The raw liquid pump valve integrated module of the present invention includes a pump valve housing, a raw liquid pump, a raw liquid pipeline, a raw liquid solenoid valve, a first check valve, and a second check valve. The raw liquid pump, raw liquid pipeline, raw liquid solenoid valve, first check valve, and second check valve are disposed inside the pump valve housing. The raw liquid pump draws raw liquid from the raw liquid pipeline into the gas-liquid mixing control module. The raw liquid solenoid valve controls the opening and closing of the raw liquid pipeline. The first check valve is provided on the front side of the raw liquid pump and the second check valve is provided on the rear side of the raw liquid pump. The pump valve housing is provided with an inlet hole and an outlet hole. The inlet end of the raw liquid pipeline is connected to the raw liquid outlet hole of the storage tank through the inlet hole. The outlet end of the raw liquid pipeline is connected to the inlet of the gas-liquid mixing control module through the outlet hole. The solenoid valve for the raw material is used to control the flow of the raw material, ensuring that the amount of raw material entering the gas-liquid mixing module meets the requirements for preparing hypochlorous acid disinfectant. The check valve is used to prevent liquid backflow. A check valve is installed on the back side of the raw material pump to prevent liquid from flowing back into the raw material pump, and a check valve is installed on the front side of the raw material pump to prevent the raw material from flowing back into the raw material tank, thus ensuring the quality of the prepared disinfectant. The components and pipelines are integrated into the pump and valve housing, which has a high degree of integration, is convenient for installation and maintenance, occupies little space, and is easy to repair and replace. The modular assembly method facilitates assembly on the production line.

[0008] The raw material pump described in this invention is an injection pump, and the raw material solenoid valve is a two-position three-way solenoid valve with interface one, interface two, and interface three. Interface one of the raw material solenoid valve is connected to the storage module via a raw material pipeline, interface two is connected to the injection pump via a raw material pipeline, and interface three is connected to the gas-liquid mixing control module via a raw material pipeline. When the controller controls the raw material solenoid valve to connect interface one and interface two, and close interface two and interface three, the raw material in the storage module flows into the injection pump. When the controller controls the interface one and interface two to close, and interface two and interface three to connect, the raw material in the injection pump is pumped into the gas-liquid mixing control module.

[0009] The gas supply module of the present invention includes a carbon dioxide cylinder, a weighing module, and a limiting component. The carbon dioxide cylinder is weighed by the weighing module and limited by the limiting component. The weighing module can weigh the carbon dioxide cylinder to realize real-time monitoring of the amount of gas in the carbon dioxide cylinder, and the limiting component can ensure the stability of the carbon dioxide cylinder and ensure measurement accuracy.

[0010] The liquid inlet and outlet measurement and control device of the present invention is provided with a base, and a water channel, a liquid outlet channel and a gas channel are opened in the base. A water inlet solenoid valve is installed on the base at the water channel position, a liquid outlet solenoid valve is installed at the liquid outlet channel position, and an air inlet solenoid valve is installed at the gas channel position. Water enters the water channel through the inlet connector and enters the water inlet of the gas-liquid mixing module through the outlet connector. Carbon dioxide enters the gas channel through the gas inlet connector and enters the gas inlet of the gas-liquid mixing module through the gas outlet connector. The raw liquid also enters the gas-liquid mixing module through the pipeline. After the water, carbon dioxide and raw liquid react in the gas-liquid mixing module, they form hypochlorous acid disinfectant. The hypochlorous acid disinfectant enters the mixing connector from the mixing outlet of the gas-liquid mixing module and then flows into the hypochlorous acid storage tank through the liquid outlet channel. The water inlet solenoid valve, liquid outlet solenoid valve and gas inlet solenoid valve are also located on the base. The whole system is modular, highly integrated, occupies little space, and is easy to assemble and maintain.

[0011] The present invention provides at least two liquid outlet channels, including liquid outlet channel one and liquid outlet channel two. The liquid outlet solenoid valve includes liquid outlet solenoid valve one and liquid outlet solenoid valve two. Liquid outlet solenoid valve one is installed on liquid outlet channel one, and liquid outlet solenoid valve two is installed on liquid outlet channel two. One end of the liquid outlet channel one is connected to the liquid outlet connector one, and the other end is connected to the mixing connector. One end of the liquid outlet channel two is connected to the liquid outlet connector two, and the other end is connected to the mixing connector. By setting up multiple outlet channels and outlet solenoid valves, the flow of disinfectant in each outlet channel is controlled by the outlet solenoid valve. When preparing disinfectant of different concentrations, the controller controls the opening of different outlet solenoid valves, and the prepared hypochlorous acid disinfectant enters different storage tanks from different outlet channels through the mixing connector, which can meet the preparation of hypochlorous acid disinfectant of different concentrations.

[0012] The gas channel of the present invention is fixed with a flow control plate to divide the gas channel into an inlet channel and an outlet channel, and the flow control plate is provided with a pressure regulating hole that penetrates the inlet channel and the outlet channel; A gas pressure sensor is provided on the gas channel. The gas pressure sensor includes a gas pressure sensor one and a gas pressure sensor two. The gas pressure sensor one is installed on the inlet channel, and the gas pressure sensor two is installed on the outlet channel. A flow regulating valve is provided on the outlet channel behind the gas pressure sensor two. By setting up a flow control plate and opening a pressure regulating hole, a pressure difference can be formed between the inlet and outlet channels. Gas pressure sensor 1 and gas pressure sensor 2 transmit the detected pressure values ​​in the pipe to the controller. The controller calculates the carbon dioxide flow rate based on the pressure difference value. The controller matches the calculated flow rate value with the set flow rate value and controls the gas flow rate in the outlet channel through the flow regulating valve to ensure that the carbon dioxide flow rate entering the gas-liquid mixing control module is appropriate and the flow rate is stable, thus forming a closed-loop regulation and control of the carbon dioxide gas flow rate.

[0013] The water channel of this invention is further equipped with a water flow sensor and / or a water pressure sensor; the outlet channel is equipped with at least one of a mixing pressure sensor, a pH meter, and an available chlorine detector; the water flow sensor and water pressure sensor upload the detected data to the controller, which adjusts the inlet water flow rate according to the target concentration to ensure the accuracy of the prepared disinfectant concentration; the pH meter is used to detect the pH value of the prepared hypochlorous acid disinfectant, the available chlorine detector is used to measure the available chlorine content of the prepared hypochlorous acid disinfectant, and the mixing pressure sensor is used to measure the outlet pressure of the hypochlorous acid disinfectant.

[0014] The beneficial effects of this invention are as follows: The integration of various modules for preparing hypochlorous acid disinfectant facilitates installation, inspection, maintenance, and replacement, and also facilitates assembly line production. The inclusion of a liquid storage module enables automatic filling, eliminating the need for manual filling, effectively preventing liquid leakage during filling, ensuring the sealing of the filling, and reducing contamination of the original liquid. The integration of pump and valve components and pipelines into the pump and valve housing results in high integration and convenient installation and maintenance. The gas supply module enables real-time monitoring of the gas volume in the carbon dioxide cylinder, ensuring the stability of the carbon dioxide cylinder and guaranteeing measurement accuracy. The inlet and outlet liquid measurement and control device integrates pipelines and solenoid valves, resulting in high integration and facilitating maintenance. Attached Figure Description

Detailed Implementation

[0057] The present invention will now be described in conjunction with the accompanying drawings and embodiments.

[0058] As attached Figure 1-4 As shown, a modular and digital hypochlorous acid disinfectant generator includes a generator housing 1, a liquid storage module 3, a water supply module, a gas supply module 4, a raw liquid pump and valve integrated module 5, an inlet and outlet liquid measurement and control module 6, and a gas-liquid mixing control module 7. The raw liquid pump and valve integrated module 5, the inlet and outlet liquid measurement and control module 6, and the gas-liquid mixing control module 7 are located inside the generator housing 1, while the water supply module, the gas supply module, and the liquid storage module are located inside the generator housing 1 or outside the generator housing 1. The gas-liquid mixing control module 7 is provided with a water inlet 7022, an air inlet 7021, a liquid inlet 7023, and a mixed liquid outlet 7024. The water supply module is connected to the water inlet of the gas-liquid mixing control module 7 via the liquid inlet / outlet measurement and control module 6 to supply water to the gas-liquid mixing control module 7. The air supply module 4 is connected to the air inlet of the gas-liquid mixing control module 7 via the liquid inlet / outlet measurement and control module 6 to supply air to the gas-liquid mixing control module 7. The liquid storage module 3 is connected to the liquid inlet of the gas-liquid mixing control module 7 via the raw liquid pump valve integration module 5 to supply raw liquid to the gas-liquid mixing control module 7. The mixed liquid outlet of the gas-liquid mixing control module 7 is connected to an external liquid storage tank via the liquid inlet / outlet measurement and control module 6. The various modules for preparing hypochlorous acid disinfectant are integrated, which facilitates installation, inspection, maintenance and replacement, and also facilitates assembly on the production line.

[0059] As attached Figure 10-20 As shown, the liquid storage module 3 includes a liquid storage tank 301 and a raw liquid tank 305. The raw liquid tank 305 includes a tank body 3051 and a liquid outlet 3052. A sealing film is attached to the liquid outlet 3052 to seal the raw liquid in the tank. In this embodiment, the top of the liquid storage tank 301 is provided with an opening, and a liquid storage cover 302 is provided at the opening. The liquid storage cover 302 includes an upper cover plate 3021 and a circumferential limiting plate 3022. The circumferential limiting plate 3022 surrounds the upper cover plate 3021, and the upper end of the circumferential limiting plate 3022 is fixedly connected to the upper cover plate 3021. The circumferential limiting plate 3022 is inserted into the opening to achieve sealing of the liquid storage tank.

[0060] The upper cover plate 3021 extends downward or upward in the middle to form an inverted frustum-shaped limiting groove 3023 that runs through the top and bottom. A raw liquid tank connecting sleeve 3024 is provided coaxially below or inside the inverted frustum-shaped limiting groove 3023. In this embodiment, the inverted frustum-shaped limiting groove 3023 extends downward into the storage tank. The raw liquid tank connecting sleeve 3024 is located below the inverted frustum-shaped limiting groove 3023. The upper end of the raw liquid tank connecting sleeve 3024 is connected to the small diameter end of the inverted frustum-shaped limiting groove 3023. The upper end of the barrel body 3051 of the raw liquid barrel 305 is set as a frustum shape that cooperates with the inverted frustum-shaped limiting groove 3023. The upper end of the inverted barrel body of the raw liquid barrel 305 is inserted into the inverted frustum-shaped limiting groove 3023, and the liquid outlet 3052 is inserted into the raw liquid barrel connecting sleeve 3024; to further ensure the stability of the raw liquid barrel.

[0061] The original liquid tank connecting sleeve 3024 is equipped with a film-opening component. The inverted liquid outlet 3052 of the original liquid tank is inserted into the original liquid tank connecting sleeve. The sealing film is pierced through the film-opening component, and the original liquid in the original liquid tank flows out through the liquid outlet into the storage tank. The operation is simple. Just invert the sealed original liquid tank 305 onto the storage tank 301 to achieve automatic filling without manual filling. This effectively prevents liquid leakage during filling, ensures the sealing of the filling, and reduces contamination of the original liquid.

[0062] The original liquid tank connecting sleeve 3024 is provided with an internal thread 3025, and the liquid outlet 3052 of the original liquid tank 305 is provided with an external thread 3053. The original liquid tank connecting sleeve 3024 is threadedly connected to the liquid outlet 3052 to realize the connection between the original liquid tank 305 and the liquid storage tank 301 and to ensure the stability and sealing of the connection.

[0063] The opening device adopts an opening and guiding sleeve 3027 that is arranged vertically. The top of the opening and guiding sleeve 3027 is set into a pointed shape that can be inserted through the sealing liquid membrane. The inside is arranged vertically and vertically to communicate with the storage tank 301. It can not only insert the sealing liquid membrane, but also allow the liquid in the original liquid tank 305 to flow into the storage tank 301 through the inside of the opening and guiding sleeve 3027.

[0064] The upper surface of the opening-film guide sleeve 3027 is set as an inclined surface, and the top of the inclined surface forms a pointed shape that can penetrate the sealing liquid membrane. The inclined surface not only ensures that the sealing liquid membrane can be penetrated, but also ensures that the liquid in the original liquid tank 305 can flow smoothly from the inside of the opening-film guide sleeve into the liquid storage tank 301 along the inclined surface, reducing liquid splashing.

[0065] A sealing plate 3026 is fixed to the bottom of the raw liquid tank connecting sleeve 3024. The sealing plate 3026 has a raw liquid opening 30261. The film-opening guide sleeve 3027 is fixed at the raw liquid opening 30261 and communicates with the raw liquid opening 30261. The film-opening guide sleeve 3027 also has an opening groove 30272 communicating with the raw liquid opening. The sealing plate 3026 ensures that the raw liquid in the raw liquid tank 305 can only flow into the storage tank 301 through the inside of the film-opening guide sleeve 3027, preventing raw liquid splashing. The opening groove 30272 can also effectively prevent some overflowing raw liquid from entering the storage tank 301 through the opening groove and raw liquid opening, so that there is no raw liquid waste.

[0066] In this embodiment, the opening groove 30272 is formed on the upper surface of the film-opening guide sleeve 3027 and located at the bottom of the slope. It penetrates the side wall of the film-opening guide sleeve 3027 radially, so that the raw liquid flowing into the raw liquid tank connecting sleeve 3024 can enter the interior of the film-opening guide sleeve 3027 along the opening groove 30272 and then flow into the storage tank 301 from the raw liquid opening 30261.

[0067] The upper cover plate 3021 is provided with an exhaust hole 30211, so that when the original liquid tank 305 fills the original liquid into the storage tank 301, the gas in the storage tank 301 can be discharged from the exhaust hole 30211.

[0068] The liquid storage tank 301 is equipped with a built-in liquid level sensor inside and / or an external liquid level sensor outside the liquid storage tank to detect the liquid level of the original liquid in the liquid storage tank. When the built-in liquid level sensor and the external liquid level sensor are used at the same time, the accuracy and reliability of the measurement are further guaranteed.

[0069] The built-in liquid level sensor is an electrode liquid level sensor 304, which is connected to the controller. The electrode liquid level sensor 304 includes an electrode fixing head, an electrode insulating component, and an electrode core. The electrode core is made of a conductive and corrosion-resistant material. In this embodiment, the electrode core includes electrode core one 30411, electrode core two 30412, electrode core three 30413, and electrode core four 30414. Electrode core one 30411, electrode core two 30412, electrode core three 30413, and electrode core four 30414. Electrode core 2 (30412), electrode core 3 (30413), and electrode core 4 (30414) have different lengths and are used to detect different liquid levels. Electrode core 1 (30411), electrode core 2 (30412), electrode core 3 (30413), and electrode core 4 (30414) are separated by electrode insulating components. The upper ends of electrode core 1 (30411), electrode core 2 (30412), electrode core 3 (30413), and electrode core 4 (30414) are respectively connected to the electrode fixing head. The electrode insulation component uses electrode protective sleeves with the same number as the electrode cores. These protective sleeves are made of insulating and corrosion-resistant material. Each protective sleeve includes electrode one protective sleeve 30421, electrode two protective sleeve 30422, electrode three protective sleeve 30423, and electrode four protective sleeve 30424, each with different lengths.

The electrode core 30414 is inserted into the electrode core 30434 of the electrode core 30424, with its lower end protruding from the electrode core 30433. Adjacent electrode cores are fixedly connected. 30421, Electrode 2 Protective Sleeve; 30422, Electrode 3 Protective Sleeve; 30423, Electrode 4 Protective Sleeve; 30424 The upper end is connected to the electrode fixing head; The electrode core is corrosion resistant, will not contaminate the liquid, is not prone to failure, has high reliability, long service life, and high detection accuracy. The structure of the electrode protective sleeve can not only ensure that the electrode core is isolated to prevent conductivity, but also further prevent the electrode core from corrosion. The connection between the electrode protective sleeve and the electrode fixing head can also ensure the stability of use.

[0070] In this embodiment, the electrode core is long, and the corresponding electrode protective sleeve is also long. The length ratio of the electrode protective sleeve 30421, electrode protective sleeve 30422, electrode protective sleeve 30423, and electrode protective sleeve 30424 is consistent with the length ratio of electrode core 30411, electrode core 30412, electrode core 30413, and electrode core 30414. Only the lower end of the electrode core is exposed through the electrode protective sleeve, which further protects the electrode core.

[0071] The electrode fixing head includes a limiting plate 3046, a threaded connecting post 3044, and a nut 3045. The threaded connecting post 3044, the limiting plate 3046, and the electrode core are arranged sequentially from top to bottom. The outer diameter of the limiting plate 3046 is larger than the outer diameter of the threaded connecting post 3044. The electrode core and the electrode protective sleeve are connected to the limiting plate 3046. The limiting plate 3046 is fixedly connected to the threaded connecting post 3044.

The electrode core is fixedly connected to the limiting disk 3046, and the upper end of the electrode core extends into the threaded connecting post 3044. A partition 3047 is fixed inside the threaded connecting post 3044, which separates adjacent electrode cores. This facilitates the installation and fixation of the electrode cores and effectively prevents adjacent electrode cores from contacting and conducting, thus affecting the liquid level detection effect.

[0072] The limiting plate 3046 has a left limiting groove 30461 on the left side and a right limiting groove 30462 on the right side. The upper cover plate has a sensor through hole 30212 for a threaded connecting post 3044 to pass through. A left limiting post is fixed to the left side of the sensor through hole, and a right limiting post is fixed to the right side of the inner wall of the upper cover plate. The electrode level sensor is vertically installed in the storage tank 301. The threaded connecting post 3044 passes through the sensor through hole 30212 of the upper cover plate 3021. An O-ring 3048 is fitted on the threaded connecting post 3044. The O-ring 3048 abuts against the inner wall of the limiting plate 3046 and the upper cover plate 3021. The nut 3045 is threadedly connected to the threaded connecting post 3044 and abuts against the upper cover plate 3021.

There are at least two capacitive sensors, including a high liquid level capacitive sensor 3031 and a low liquid level capacitive sensor 3032. The high liquid level capacitive sensor 3031 is located above the low liquid level capacitive sensor 3032. The high liquid level capacitive sensor 3031 and the low liquid level capacitive sensor 3032 are respectively fixed to the outer wall of the liquid storage tank 301.

[0075] The outer wall of the liquid storage tank 301 is fixed with a high-level upper horizontal baffle 30111, a high-level lower horizontal baffle 30112, a low-level upper horizontal baffle 30113, and a low-level lower horizontal baffle 30114. The high-level capacitive sensor 3031 is fixed between the high-level upper horizontal baffle 30111 and the high-level lower horizontal baffle 30112, and the low-level capacitive sensor 3032 is fixed between the low-level upper horizontal baffle 30113 and the low-level lower horizontal baffle 30114. This facilitates the installation of the capacitive sensors, ensures the accuracy of the installation position of the capacitive sensors, and guarantees the detection accuracy.

[0076] The bottom of the storage tank is provided with a raw liquid outlet hole 30115. The raw liquid in the storage tank flows out from the raw liquid outlet hole and is connected to the inlet end of the raw liquid pipeline through the inlet hole 5091 of the raw liquid pump valve integrated module 5.

[0077] In this embodiment, an electronic tag is fixed on the stock solution tank 305. The electronic tag is read by a card reader. The card reader is located on or inside the generator housing and connected to the controller. By setting the electronic tag and cooperating with the card reader, the card reader can read the information of the stock solution tank and feed it back to the controller. The controller identifies whether it is a dedicated stock solution tank, ensuring that the stock solution used meets the requirements and that the concentration and quality of the prepared hypochlorous acid disinfectant meet the requirements.

[0078] As attached Figure 3 , Figure 5-9 As shown, the gas supply module 4 includes a carbon dioxide cylinder 401, a weighing module 405, and a limiting component. The carbon dioxide cylinder 401 is weighed by the weighing module and limited by the limiting component. The weighing module can weigh the carbon dioxide cylinder 401 to realize real-time monitoring of the amount of carbon dioxide in the carbon dioxide cylinder 401. The limiting component can ensure the stability of the carbon dioxide cylinder 401 and ensure measurement accuracy.

[0079] In this embodiment, the weighing module 405 is located below the carbon dioxide cylinder 401. The weighing module 405 includes a base plate 4051 and a weighing sensor 4053.

The weighing sensor 4053 is provided in the cylinder limiting groove. The carbon dioxide cylinder 401 is placed on the weighing sensor 4053. The bottom of the carbon dioxide cylinder 401 is limited circumferentially by the cylinder enclosure plate 4052. The weighing sensor is connected to a controller. This configuration enables the weighing of the carbon dioxide cylinder 401 and real-time monitoring of the amount of carbon dioxide in the cylinder, while also ensuring the stability of the carbon dioxide cylinder 401.

[0080] The base plate has an upward-facing sensor placement slot 40511, in which the weighing sensor 4053 is placed. A gas cylinder support plate 4054 is provided on the weighing sensor 4053, and the carbon dioxide gas cylinder 401 is placed on the gas cylinder support plate 4054. This structural arrangement further ensures the stability of the gas cylinder support, while reducing the direct contact between the carbon dioxide gas cylinder 401 and the weighing sensor 4053, thus reducing the wear on the weighing sensor 4053.

[0081] In this embodiment, the weighing sensor 4053 is a spoke-type weighing sensor. However, it is not limited to this type of sensor. Other types of sensors can also be used as long as they can weigh carbon dioxide cylinders.

[0082] The diameter of the sensor placement slot 40511 is smaller than the diameter of the base plate 4051. The upper end of the load cell 4053 extends radially outward to form a limiting boss. The load cell 4053 is placed in the sensor placement slot 40511. The lower surface of the limiting boss abuts against the base plate 4051 and is connected to the base plate 4051. This enables quick installation and positioning of the load cell. In this embodiment, the limiting boss has several bolt holes spaced circumferentially along its edge. The base plate 4051 has several threaded holes. Bolts pass through the bolt holes on the limiting boss and are threadedly connected to the threaded holes, enabling the load cell 4053 to be detachably fixed, facilitating installation and maintenance.

[0083] In this embodiment, the weighing sensor 4053 has an internal threaded hole in the middle, and the bottom of the gas cylinder support plate 4054 is fixed with an external threaded post 4055. The external threaded post is fixed in the middle of the gas cylinder support plate 4054, and the gas cylinder support plate 4054 is located in the gas cylinder limiting groove. The external threaded post 4055 is inserted into the internal threaded hole and threadedly connected, thereby fixing the position of the gas cylinder support plate 4054. It is not limited to this. Alternatively, one of the limiting groove and the limiting post can be set on the weighing sensor, and the other of the limiting groove and the limiting post can be set on the gas cylinder support plate. The position of the gas cylinder support plate can be fixed by the insertion of the limiting groove and the limiting post. Alternatively, the gas cylinder support plate can be directly placed on the weighing sensor.

[0084] The limiting component also includes a mounting plate 2 and a gas cylinder bracket 404. The gas cylinder bracket 404 is provided with an arc-shaped groove with its opening facing the carbon dioxide gas cylinder 401. The body of the carbon dioxide gas cylinder 401 rests in the arc-shaped groove, and the gas cylinder bracket 404 is fixed on the mounting plate 2. The body of the carbon dioxide gas cylinder 401 is stuck in the arc-shaped groove, which limits the position of the gas cylinder and ensures its stability.

[0085] The limiting component also includes a cylinder strap 403, which binds the body of the carbon dioxide cylinder 401 and connects it to the mounting plate 2; this further ensures the stability of the carbon dioxide cylinder placement and the weighing accuracy. When the carbon dioxide cylinder needs to be replaced, the cylinder strap can be untied.

[0086] The outlet of the carbon dioxide cylinder 401 is connected to a pressure reducing valve 402, and the outlet of the carbon dioxide cylinder is connected to the internal air inlet connector 6076 of the liquid inlet / outlet measurement and control module via a pipeline.

The liquid inlet end 5061 of the raw liquid pipeline is connected to the liquid inlet 5091, and the liquid outlet end 5062 of the raw liquid pipeline is connected to the liquid outlet 5092. The raw liquid in the storage tank enters the raw liquid pump valve integrated module through the liquid inlet end of the raw liquid pipeline, and then enters the liquid inlet of the gas-liquid mixing control module through the liquid outlet end of the raw liquid pipeline. An electrical plug socket is provided on the pump valve housing 501. The electrical wiring inside the pump valve housing is connected to the inside of the electrical plug socket, and the external electrical wiring is connected to the electrical plug. The components and pipelines are integrated into the pump and valve housing 501, which has a high degree of integration, is convenient for installation and maintenance, and occupies little space. The raw material solenoid valve 505 is used to control the flow of raw material, ensuring that the amount of raw material entering the gas-liquid mixing control module meets the requirements for the preparation of hypochlorous acid disinfectant. The one-way valve 2 can prevent liquid from flowing back into the raw material pump, and the one-way valve 1 can prevent raw material from flowing back into the raw material tank, thus ensuring the quality of the prepared hypochlorous acid disinfectant.

The second outlet 5042 of the one-way valve 504 is connected to the outlet end 5062 of the raw liquid pipeline via a pipeline. When the controller controls the connection of interface 1 5051 and interface 2 5052 of the raw liquid solenoid valve, and the connection of interface 2 5052 and interface 3 5053, the raw liquid in the storage tank flows into the injection pump 502 through the raw liquid through hole 5021. When the controller controls the connection of interface 1 5051 and interface 2 5052, and the connection of interface 2 5052 and interface 3 5053, the raw liquid in the injection pump 502 flows through interface 2 and interface 3 of the raw liquid solenoid valve and is pressed into the gas-liquid mixing control module.

The flow control plug 60924 is sized to fit the flow control groove 60883, and is inserted into the flow control groove 60883. The front sidewall of the flow control groove 60883 is connected to the front section of the pipe to form a first fluid passage 60881. The connection between the upper surface of the rear sidewall of the flow control groove 60883 and the lower end of the bushing is connected to the rear section of the pipe to form a second fluid passage 60882. The fluid in the front section of the pipe flows sequentially through the first fluid passage 60881, the flow control groove 60883, and the second fluid passage 60882 before entering the rear section of the pipe. The cooperation between the flow blocking block 60884 and the flow control column 6092 allows for precise adjustment of the flow rate based on the position of the flow control column 6092 in the flow control groove 60883. When the flow control plug 60924 is fully inserted into the flow control groove 60883, the fluid passage can be disconnected.

[0107] The drive mechanism uses a motor 6091, which is connected to a controller. The upper end of the column 60926 has an internal threaded hole 60921 along the axial direction. The motor shaft of the motor 6091 has an external thread. The motor shaft of the motor 6091 extends into the internal threaded hole 60921 and is threadedly connected to the column 60926. The rotation of the motor shaft drives the flow control column to move axially.

[0108] The bushing 6022 includes an upper bushing 60221 and a lower bushing 60222 coaxially arranged. The inner diameter of the upper bushing 60221 is larger than the inner diameter of the lower bushing 60222. A horizontal limiting end face is formed between the upper bushing 60221 and the lower bushing 60222. The upper end of the column 60926 extends radially outward to form a limiting boss 60925. The outer diameter of the limiting boss 60925 matches the inner diameter of the upper bushing 60221, the outer diameter of the column 60926 matches the inner diameter of the lower bushing 60222, and the lower surface of the limiting boss 60925 matches the horizontal limiting end face. The outer diameter of the large-diameter end of the flow control plug 60924 is smaller than the outer diameter of the lower surface of the column 60926. A lower limiting surface is formed between the large-diameter end of the flow control plug 60924 and the lower surface of the column 60926. The flow control plug 60924 is inserted into the flow control groove 60883, and the lower limiting surface abuts against the upper surface of the flow blocking block 60884. The lower end of the column 60926 is provided with a sealing groove 60927 along the circumference, and a sealing ring is provided in the sealing groove 60927; used to achieve sealing between the flow control column and the inner wall of the bushing.

[0109] When the flow control plug 60924 is fully inserted into the flow control groove 60883, the lower limit surface abuts against the upper surface of the flow blocking block, which can block the connection between the flow control groove 60883 and the fluid through hole 60882.

[0110] The limiting boss 60925 has a left vertical surface 60922 on the left side and a right vertical surface 60923 on the right side of its outer wall. The upper bushing 60221 has a left guide surface 60223 on the left side and a right guide surface 60224 on the right side of its inner wall. The left vertical surface 60922 on the outer wall of the limiting boss 60925 is in contact with the left guide surface 60223 on the inner wall of the upper bushing 60221, and the right vertical surface 60923 is in contact with the right guide surface 60224 on the inner wall of the upper bushing 60221. The flow control column 6092 slides along the left guide surface 60223 and the right guide surface 60224 on the inner wall of the upper bushing 60221 to limit the sliding direction of the flow control column. It can only move along the axial direction of the bushing 6022 and cannot rotate circumferentially, thus ensuring the accuracy of the flow control column in regulating the flow rate.

[0111] The water outlet channel is also equipped with a water flow sensor 6051 and a water pressure sensor 6052, which are respectively connected to the controller. The water flow sensor 6051 and the water pressure sensor 6052 upload the detected data to the controller. The controller adjusts the inlet water flow according to the target concentration to ensure the accuracy of the concentration of the prepared hypochlorous acid disinfectant.

[0112] The mixing channel is equipped with a pH meter 6056 and an available chlorine detector 6057. The pH meter 6056 and the available chlorine detector 6057 are respectively connected to the controller. The pH meter is used to measure the pH value of the hypochlorous acid disinfectant prepared by mixing water, hypochlorous acid stock solution and carbon dioxide. The available chlorine detector is used to measure the available chlorine content in the hypochlorous acid disinfectant prepared by mixing water, hypochlorous acid stock solution and carbon dioxide.

[0113] In this embodiment, a second mixing channel is also provided in the right base. The left side of the second mixing channel is connected to the liquid outlet channel, and the right side is closed and does not penetrate the right base. A mixing pressure sensor 6055 is installed on the second mixing channel to detect the pressure of the disinfectant. The mixing pressure sensor 6055 is connected to the controller.

The liquid mixing channel 7035 and the water inlet channel 7031 are connected at one end away from the water inlet 7022 and at the other end of the original liquid channel 7032 away from the liquid inlet 7023 to form a connecting section one. One end of the liquid-liquid mixing channel 7033 is connected to the connecting section one, and the other end is connected to the air inlet channel 7034 away from the air inlet 7021 to form a connecting section two. One end of the gas-liquid mixing channel 7035 is connected to the connecting section two, and the other end is connected to the mixed liquid outlet 7024.

[0116] In this embodiment, the gas-liquid mixing housing 701 includes a rear upright plate 7011 and a front cover plate 7012. The rear upright plate 7011 has grooved water inlet channel 1, raw liquid channel 1, air inlet channel 1, liquid-liquid mixing channel 1, and gas-liquid mixing channel 1. The front cover plate 7012 has grooved water inlet channel 2, raw liquid channel 2, air inlet channel 2, liquid-liquid mixing channel 2, and gas-liquid mixing channel 2. When the rear upright plate 7011 and the front cover plate 7012 are connected, water inlet channel 1 and water inlet channel 2 are connected to form a complete water inlet channel, raw liquid channel 1 and raw liquid channel 2 are connected to form a complete raw liquid channel, air inlet channel 1 and air inlet channel 2 are connected to form a complete air inlet channel, liquid-liquid mixing channel 1 and liquid-liquid mixing channel 2 are connected to form a complete liquid-liquid mixing channel, and gas-liquid mixing channel 1 and gas-liquid mixing channel 2 are connected to form a complete gas-liquid mixing channel. A sealing strip is provided at the channel connection point to ensure sealing, so that gas and liquid will not leak, and processing, assembly, and maintenance are convenient.

[0117] In this embodiment, the rear upright plate 7011 is provided with one of a groove and an insert, and the front cover plate 7012 is provided with the other of a groove and an insert. The insert and the groove are inserted and matched to limit the rear upright plate 7011 and the front cover plate 7012. After the rear upright plate 7011 and the front cover plate 7012 are limited, they are fixed by bolts.

[0118] In this embodiment, spiral blades 704 are installed in the liquid-liquid mixing channel 7033 and the gas-liquid mixing channel 7035. Several spiral blades 704 are provided. One of the grooves and one of the protrusions is opened on the front end face of the spiral blade 704, and the other of the groove and one of the protrusions is opened on the rear end face. Several spiral blades 704 are arranged close together along the length direction of the liquid-liquid mixing channel 7033 and the gas-liquid mixing channel 7035. Adjacent spiral blades 704 are limited by the insertion and cooperation of the grooves and protrusions. The insertion and arrangement of several spiral blades 704 facilitates processing.

Filling the concentrate: Bring the electronic tag on the concentrate tank 305 close to the card reader. The card reader identifies the electronic tag data and sends the information back to the controller. Open the lid of the concentrate tank 305 and invert the concentrate tank 305. Insert the dispensing nozzle 3052 into the concentrate tank connecting sleeve 3024. The upper end of the frustoconical shape of the concentrate tank body 3051 engages with the inverted frustoconical limiting groove 3023. Rotate the concentrate tank 305 to thread the dispensing nozzle 3052 into the concentrate tank connecting sleeve 3024. The dispensing nozzle 3052 is inserted into the concentrate tank connecting sleeve 3024, and the tip of the opening-film guide sleeve 3027 pierces the sealing membrane, allowing the concentrate in the concentrate tank 305 to flow out from the dispensing nozzle 3052, through the inside of the opening-film guide sleeve 3027, and into the storage tank 3 via the concentrate opening 30261. In step 01, some of the raw liquid that overflows to the outside of the opening-film guide sleeve 3027 can flow back into the opening-film guide sleeve 3027 through the opening groove 30272; the electrode liquid level sensor 304 detects the liquid level in the storage tank 301 and feeds the signal back to the controller; the capacitive sensor senses the liquid level inside the storage tank outside the storage tank and feeds the signal back to the controller; the built-in and external sensors work together to ensure detection accuracy; if the card reader can recognize the electronic tag of the raw liquid tank, the controller controls the injection pump of the raw liquid pump valve integrated module to work and controls the raw liquid solenoid valve, water inlet solenoid valve, and air inlet solenoid valve to start and open the pipeline; if the card reader does not recognize the electronic tag of the raw liquid tank, the injection pump does not work and the raw liquid solenoid valve, water inlet solenoid valve, and air inlet solenoid valve disconnect the pipeline. 3. The controller selects the production mode according to the set target concentration. When production mode 1 is selected, the controller controls the liquid outlet solenoid valve 1 6041, the water inlet solenoid valve 603, and the internal air inlet solenoid valve 6062 (in this embodiment, air is supplied by a built-in carbon dioxide cylinder) to open. At this time, the liquid outlet solenoid valve 2 6042 and the liquid outlet solenoid valve 3 6043 are closed. After the water is pressurized by the water pump, it passes through the water inlet connector 6071, the water channel 6081, and the water outlet connector 6078 in sequence and enters the water inlet of the gas-liquid mixing control module 7. The controller connects interface 1 (5051) and interface 2 (5052) of the raw liquid solenoid valve, and closes interface 2 (5052) and interface 3 (5053). The raw liquid in the storage tank is drawn in sequence through the raw liquid outlet, the raw liquid inlet 5061, the inlet 5031 of check valve 1, the outlet 5032 of check valve 1, interface 1 (5051) of the raw liquid solenoid valve 505, and interface 2 (5052) of the raw liquid solenoid valve, entering the raw liquid through-hole 5021 of the injection pump 502. The controller closes interface 1 (5051) and interface 2 (5052) of the raw liquid solenoid valve, and closes interface 2 (5052) of the raw liquid solenoid valve. The raw liquid in the injection pump 502 passes through the raw liquid through hole 5021, the interface 2 of the raw liquid solenoid valve 5052, the interface 3 of the raw liquid solenoid valve 5053, the inlet 2 of the one-way valve 5041, the outlet 2 of the one-way valve 5042, and the outlet end 5062 of the raw liquid pipeline before entering the inlet 7023 of the gas-liquid mixing control module 7. The injection pump automatically adjusts the discharge speed according to the discharge concentration corresponding to the current production mode and the current water flow rate so that the raw liquid, water and carbon dioxide enter the hypochlorous acid generation module to react and generate the hypochlorous acid concentration required for production mode 1. Carbon dioxide in carbon dioxide cylinder 401 passes sequentially through pressure reducing valve 402, internal air inlet connector 6076, internal air inlet channel 6087, flow control plate 6010, air outlet channel 6088, and air outlet connector 6077 before entering air inlet 7021 of gas-liquid mixing control module 7. The raw liquid flows into the liquid-liquid mixing channel 7033 through the raw liquid channel 7032 of the gas-liquid mixing control module 7. Water flows into the liquid-liquid mixing channel 7033 through the water inlet channel 7031 of the gas-liquid mixing control module 7. The raw liquid and water are mixed in the liquid-liquid mixing channel 7033 and flow into the gas-liquid mixing channel 7035. Carbon dioxide flows into the gas-liquid mixing channel 7035 through the gas inlet channel 7034. The liquid after mixing the raw liquid and water and the carbon dioxide are mixed in the gas-liquid mixing channel 7035 to form a hypochlorous acid disinfectant solution with the concentration required for production mode 1. Then, it flows into the storage tank 1 sequentially from the mixing outlet 7024, the mixing connector 6079 of the inlet and outlet liquid measurement and control module, the mixing channel, the outlet channel 6082, and the outlet connector 6072. 4. When production mode 2 is selected, the controller controls the opening of the liquid outlet solenoid valve 2 6042, the water inlet solenoid valve 603, and the internal air inlet solenoid valve 6062, and the closing of the liquid outlet solenoid valve 1 6041 and the liquid outlet solenoid valve 3 6043. Repeat step 3. After the raw liquid, water and carbon dioxide enter the gas-liquid mixing control module 7, they react to generate hypochlorous acid disinfectant solution of the required concentration for production mode 2. The solution enters the mixing channel from the mixing outlet of the gas-liquid mixing control module 7, and then enters the storage tank 2 from the liquid outlet channel 2 6083. 5. When production mode 3 is selected, the controller controls the opening of the liquid outlet solenoid valve 6043, the water inlet solenoid valve, and the internal air inlet solenoid valve, while the liquid outlet solenoid valve 6041 and the liquid outlet solenoid valve 6042 are closed. The raw liquid, water, and carbon dioxide enter the gas-liquid mixing control module and react to generate hypochlorous acid disinfectant solution of the required concentration for production mode 3. The solution enters the mixing channel from the mixing outlet of the gas-liquid mixing control module and then enters the storage tank 3 from the liquid outlet channel 6084. 6. During the carbon dioxide cylinder supply process, the weighing sensor 4053 weighs the carbon dioxide cylinder 401 in real time and feeds the data back to the controller. The controller sets a weight threshold. When the weight of the cylinder fed back by the weighing sensor 4053 reaches or falls below the weight threshold, it indicates that the carbon dioxide in the cylinder is depleted and needs to be replaced. Replacement is achieved by loosening the cylinder strap 403. Gas pressure sensors one and two detect gas pressure and calculate the gas flow rate based on the pressure difference. When it is necessary to reduce the gas flow rate, the controller controls the motor shaft to rotate in the forward direction. This is because the flow control column is threaded onto the motor shaft. The flow control column 6092 is connected, and under the constraint of the left vertical surface 60922 and the right vertical surface 60923, the flow control column 6092 moves downward along the shaft sleeve 6022, and the flow control plug 60924 moves towards the bottom of the flow control groove 60883 to reduce the gas flow rate. When it is necessary to increase the gas flow rate, the controller controls the motor shaft to rotate in the opposite direction, driving the flow control column 6092 to move upward along the shaft sleeve 6022. During the supply of raw liquid, the electrode liquid level sensor, the high liquid level capacitance sensor, and the low liquid level capacitance sensor detect the liquid level in the storage tank. When the liquid level in the storage tank is detected to be low, the operator replaces the raw liquid tank with a new one. 7. A liquid level sensor is installed in the storage tank. The liquid level sensor detects the liquid level and feeds the signal back to the controller. When the liquid level sensor in storage tank 1 detects that the liquid level in storage tank 1 is low, the controller adjusts the control mode to production mode 1 and produces according to the target concentration required by production mode 1. When the liquid level sensor in storage tank 2 reports that the liquid level in storage tank 2 is low, the controller adjusts the control mode to production mode 2 and produces according to the target concentration required by production mode 2. When the liquid level sensor in storage tank 3 reports that the liquid level in storage tank 3 is low, the controller adjusts the control mode to production mode 3 and produces according to the target concentration required by production mode 3.
