Description

Technical Field

[0001] This utility model belongs to the field of sterilization and disinfection, and particularly relates to an automatic pure water sterilizer. Background Technology

[0002] Autoclaves sterilize by heating pure water to generate saturated steam. The operation and use of autoclaves are inseparable from a water source, especially pure water (filtered and purified water). Currently, the conventional operation involves manually adding water to the designated observation port. Once the controller detects that the water level in the autoclave is below the low-level value, the system will issue a command to remind the operator to add water. This adds heavy physical labor to the operator and is also prone to errors. Therefore, there is a need to develop an automatic water-adding device to achieve automation, intelligence, and user-friendliness.

[0003] To design an automated water intake function, since the water source needs to be kept on for a long time in most cases, the water pressure is consistently high. Rigid metal pipes are often required to withstand the high water pressure at the inlet. However, rigid metal pipes are not only inflexible to install and use, but also have specific requirements and selection criteria for the metal material and purity of the water pipes used for pure water delivery, which often leads to higher costs. In order to reduce costs, this patent was developed. Utility Model Content

[0004] The purpose of this invention is to provide a low-cost, highly convenient automatic pure water sterilizer that is flexible in assembly and can automatically add water.

[0005] Based on the above objectives, this patent provides an automatic pure water sterilizer, wherein the sterilizer is connected to a pure water source via an inlet pipe; a pure water single valve is provided at the connection between the inlet pipe and the pure water source; a pure water inlet is provided at the bottom of the sterilizer, and an inlet solenoid valve is provided at the pure water inlet, which is controlled to open or close; a controller is also provided, which is electrically connected to the sterilizer, the pure water single valve, and the inlet solenoid valve, for receiving signal data from inside the sterilizer and controlling the pure water single valve and / or the inlet solenoid valve to open or close; the inlet pipe is a soft water pipe.

[0006] Furthermore, the sterilization chamber of the sterilizer is equipped with a high water level gauge and a low water level gauge. The controller is further electrically connected to the high water level gauge and the low water level gauge, and is used to control the inlet solenoid valve and the pure water valve to close simultaneously based on the electrical signal emitted by the high water level gauge. At the same time, it is used to control the inlet solenoid valve and the pure water valve to open simultaneously based on the electrical signal emitted by the low water level gauge.

[0007] A water storage tank is further provided, the inlet of which is connected to a pure water source through an inlet pipe; the outlet of which is connected to the pure water inlet of the sterilizer through an inlet solenoid valve; a pure water level gauge is provided inside the water storage tank; the controller is further electrically connected to the pure water level gauge and is used to control the opening or closing of the pure water single valve and / or the inlet solenoid valve according to the signal inside the sterilizer and the water level data of the pure water level gauge.

[0008] Furthermore, the controller is also used to receive water level data from the pure water level gauge. The pure water level gauge configured in the water storage tank is only preset with a first threshold. When the water level in the water storage tank is lower than the first threshold, the pure water single valve is opened to open the inlet pipe. When the water level is higher than the first threshold, the pure water single valve is closed to close the inlet pipe. Moreover, the flow rate flowing into the water storage tank is less than the flow rate flowing out of the water storage tank.

[0009] Furthermore, the controller is also used to receive water level data from the pure water level gauge. The pure water level gauge configured in the water storage tank has preset second and third thresholds, where the second threshold is less than or equal to the third threshold. When the water level in the water storage tank is lower than the second threshold, the pure water single valve is opened to open the inlet pipe; when the water level in the water storage tank is higher than the third threshold, the pure water single valve is closed to shut off the inlet pipe.

[0010] Furthermore, the sterilization chamber of the sterilizer is equipped with a high water level gauge and a low water level gauge. The controller is further electrically connected to the high water level gauge and the low water level gauge, and is used to control the water inlet solenoid valve to close according to the electrical signal emitted by the high water level gauge and to control the water inlet solenoid valve to open according to the electrical signal emitted by the low water level gauge.

[0011] Furthermore, the pure water level gauge is a pressure level gauge, a float-type level gauge, a fiber optic level gauge, or an acoustic level gauge.

[0012] Furthermore, the outlet of the water storage tank is located at the bottom, and the inlet of the water storage tank is located at the upper part of the water storage tank; the top of the water storage tank is provided with a vent hole, which is connected to the bottom surface by a flexible hose.

[0013] Furthermore, the pure water single valve is a roller parallel single valve.

[0014] Furthermore, the material of the water inlet pipe is one of the following: food-grade PVC, PE, PP, and PA, and all of them must meet food-grade standards.

[0015] This invention features a simple structure and automated control. In particular, by utilizing the excellent sealing and pressure-bearing capacity of the pure water single valve and the inlet solenoid valve, the connection process between the pure water source and the sterilizer can use flexible soft water pipes, which are inexpensive and ensure water quality. Furthermore, the design of the pure water single valve and the inlet solenoid valve facilitates direct electrical control by the controller. Combined with the use of pure water level gauges, high water level gauges, and low water level gauges, the entire sterilizer meets the design requirements for automated pure water intake, eliminating the need for real-time manual control and achieving low-cost automated control.

[0026] like Figure 1-5As shown, an automatic pure water sterilizer 10 is connected to a pure water source (not shown in the figure) via an inlet pipe 3. A pure water single valve 31 is provided at the connection between the inlet pipe 3 and the pure water source. A pure water inlet 13 is provided at the bottom of the sterilizer 10, and a water inlet solenoid valve 2 is sealed to the pure water inlet 13. The water inlet solenoid valve 2 is controlled to open or close. In this embodiment, the pure water single valve 31 is a roller parallel single valve, such as... Figure 4 As shown.

[0027] Another controller 4 is electrically connected to the sterilizer 10, the pure water single valve 31, and the inlet solenoid valve 2. It receives signal data from within the sterilizer 10 and controls the opening and closing of the pure water single valve 31 and the inlet solenoid valve 2. Furthermore, the sterilization chamber 1 of the sterilizer 10 contains a high-level gauge 11 and a low-level gauge 12. The controller 4 is further electrically connected to the high-level gauge 11 and the low-level gauge 12, and is used to control the inlet solenoid valve 2 and the pure water single valve 31 to close simultaneously based on the electrical signal from the high-level gauge 11, and simultaneously control the inlet solenoid valve 2 and the pure water single valve 31 to open simultaneously based on the electrical signal from the low-level gauge 12. Figure 5 As shown in the control relationship diagram; in this embodiment, it is designed that when the water level is higher than the high water level gauge 11, the high water level gauge 11 triggers an electrical signal to the controller 4, and when the water level is lower than the low water level gauge 12, the low water level gauge 12 triggers an electrical signal to the controller 4.

[0028] This patent uses a pure water single valve 31 and an inlet solenoid valve 2, which are strong enough to allow the use of soft water pipes in the inlet pipe 3. The use of soft water pipes not only makes the sterilizer 10 more flexible in assembly, but also because soft water pipes are a very mature water pipe material. Not only are there many options available on the market, but they are also inexpensive and can ensure that the pure water inside is not easily contaminated; this reduces equipment costs and improves assembly convenience.

[0029] Furthermore, the pure water single valve 31 and the inlet solenoid valve 2 are electrically controlled, eliminating the need for manual switching. The switch can be controlled by the controller 4, and precise control is achieved by utilizing the feedback from the high water level gauge 11 and the low water level gauge 12. Example 2

[0030] like Figure 6-10 As shown, in this embodiment, a water storage tank 5 is further provided. The inlet 51 of the water storage tank 5 is connected to a pure water source (not shown in the figure) through an inlet pipe 3. A pure water single valve 31 is provided at the connection between the inlet pipe 3 and the pure water source. In this embodiment, an outlet pipe 54 is connected to the outlet 52 of the water storage tank 5. The outlet pipe 54 is connected to the pure water inlet 13 of the sterilizer 10 through an inlet solenoid valve 2. A pure water level gauge 53 is provided inside the water storage tank 5. A high water level gauge 11 and a low water level gauge 12 are built into the sterilization chamber 1 of the sterilizer 10.

[0031] The controller 4 is electrically connected to the high water level gauge 11, the low water level gauge 12, the pure water single valve 31, the inlet solenoid valve 2, and the pure water level gauge 53. The controller 4 is used to control the inlet solenoid valve 2 to close according to the electrical signal emitted by the high water level gauge 11 and to control the inlet solenoid valve 2 to open according to the electrical signal emitted by the low water level gauge 12. In this embodiment, it is designed that when the water level is higher than the high water level gauge 11, the high water level gauge 11 triggers an electrical signal to the controller 4, and when the water level is lower than the low water level gauge 12, the low water level gauge 12 triggers an electrical signal to the controller 4.

[0032] Meanwhile, controller 4 receives water level data from pure water level gauge 53. This pure water level gauge 53 has only one preset first threshold. When the water level in storage tank 5 is below the first threshold, the pure water single valve 31 opens to connect the inlet pipe 3; when the water level is above the first threshold, the pure water single valve 31 closes to shut off the inlet pipe 3. Furthermore, the flow rate into storage tank 5 is less than the flow rate out of storage tank 5. This ensures that when pure water is transported from storage tank 5 to sterilization chamber 1, the pure water single valve 31 will not repeatedly open / close, thus extending its service life. In this embodiment, a float level gauge is used, meaning that the float level gauge has only one high water level threshold. Figure 9 As shown, in this embodiment, its float 531 is located at Figure 9 The upper position A indicates that the water level is higher than the high water level threshold, while the lower position B of the float 531 indicates that the water level is lower than the high water level threshold.

[0033] Of course, it is also possible that the pure water level gauge configured in the water storage tank has a preset second threshold and a third threshold, where the second threshold is less than or equal to the third threshold. When the water level in the water storage tank 5 is lower than the second threshold, the pure water single valve 31 is opened to open the inlet pipe; when the water level in the water storage tank 5 is higher than the third threshold, the pure water single valve 31 is closed to shut off the inlet pipe. (Not shown in the figure)

[0034] The outlet 52 of the water storage tank 5 is located at the bottom, and the inlet 51 of the water storage tank 5 is located at the high position of the water storage tank 5. That is, pure water is injected from the bottom for sterilization and sterilization is achieved by high-temperature evaporation. This design not only meets the requirements of bottom heating to better utilize heat evaporation and achieve energy saving, but also makes better use of water pressure to transfer pure water in the water storage tank 5 to the sterilization chamber 1 of the sterilizer 10.

[0035] The outlet pipe 54 can be a soft water pipe. Due to the use of the inlet solenoid valve 2, it can better withstand the water pressure, ensuring that the soft water pipe can be used. It is flexible in assembly, low in cost, and has many options. Furthermore, a metal pipe is used at the connection between the inlet solenoid valve 2 and the sterilization chamber 1 of the sterilizer 10 to better withstand the water pressure inside the sterilizer 10 and ensure the safety of the device.

[0036] When sterilizer 10 needs water (pure water), the inlet solenoid valve 2 opens, and the pure water in the water storage tank 5 begins to flow into the sterilization chamber 1 through the inlet solenoid valve 2. At this time, the water level in the water storage tank 5 begins to drop, and the float water level gauge is at the lower position B. Then the controller 4 controls the pure water single valve 31 to open, and the external water source (pure water) enters the water storage tank 5.

[0037] When the sterilization water reaches the preset volume in the sterilizer 10 and the water level is higher than the high water level gauge 11, the high water level gauge 11 triggers an electrical signal to the controller 4, the inlet solenoid valve 2 closes and stops water intake, and the water storage tank 5 continues to add water until the float of the water level gauge is at its maximum position. Figure 9 At position A above, controller 4 controls the pure water single valve 31 to close, and the external water source stops supplying water;

[0038] Depending on usage, the automatic water replenishment and supply processes are repeated continuously. This embodiment introduces a water storage tank 5 structure to better achieve pure water storage and further enhance the control effect of automation.

[0039] The above embodiments are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and should be defined by the claims.
