Description

Technical Field

[0001] This utility model belongs to the field of sterilization and disinfection, and in particular relates to a sterilization device with a self-generated pure water function. Background Technology

[0002] Autoclaves sterilize by heating pure water to generate saturated steam. The operation and use of autoclaves rely on pure water (filtered and purified water). Currently, the conventional operation involves manually adding water to the designated observation port. If the water level falls below the preset threshold set in the low-level gauge inside the autoclave, the operator must add water again to raise the water level back to the observation port. This adds heavy physical labor to the operator and introduces errors in water addition. Therefore, an automatic water-adding device needs to be developed to achieve automation, intelligence, and user-friendliness. Utility Model Content

[0003] The purpose of this invention is to provide a sterilization device with self-generated pure water function that can automatically convert and add pure water, is low in cost, highly convenient, and has an automatic water conversion and addition function.

[0004] To achieve the above objectives, a specific method is a sterilization device with a self-generated pure water function. The sterilization device includes at least a sterilizer, a water storage tank, and a pure water machine. The inlet of the water storage tank is connected to the outlet of the pure water machine through a first pipeline, and the outlet of the water storage tank is connected to the sterilizer through a second pipeline. It also includes a first solenoid valve, a water level gauge, a second solenoid valve, and a controller.

[0005] The first solenoid valve is used to controllably open or close the first pipeline;

[0006] The water level gauge is installed inside the water storage tank and is used to detect the water level in the water storage tank and send the data to the controller.

[0007] The controller is used to receive signal data from the water level gauge and control the opening and closing of the first solenoid valve and the second solenoid valve.

[0008] The water purifier outlet is equipped with a high-pressure switch, which is used to measure the real-time water pressure in the outlet, and to close the high-pressure switch when the real-time water pressure in the outlet rises and triggers a first threshold, and to open the high-pressure switch when the water pressure drops and triggers a second threshold.

[0009] Furthermore, the water level gauge is a pressure water level gauge, a float-type water level gauge, a fiber optic water level gauge, or an acoustic water level gauge.

[0010] Furthermore, the water level gauge configured in the water storage tank has only a preset third threshold. When the water level is lower than the third threshold, the first solenoid valve is opened to connect the first pipeline. When the water level is higher than the third threshold, the first solenoid valve is closed to shut off the first pipeline. Moreover, the flow rate into the water storage tank through the first pipeline is less than the flow rate out of the water storage tank through the second pipeline.

[0011] Furthermore, the water level gauge installed in the water storage tank is preset with a fourth threshold and a fifth threshold. The fourth threshold is less than the fifth threshold. When the water level is lower than the fourth threshold, the first solenoid valve is opened to connect the first pipeline. When the water level is higher than the fifth threshold, the first solenoid valve is closed to shut off the first pipeline.

[0012] Furthermore, the sterilizer, water tank, and pure water machine of the sterilization equipment are designed as a single module or in separate sections.

[0013] Furthermore, the water outlet of the water storage tank is located at the bottom of the sterilizer, and the water inlet of the water storage tank is located at the upper part of the water storage tank.

[0014] Furthermore, the water storage tank is equipped with a vent, which is located on the top of the water storage tank and connected to the ground by a flexible hose.

[0015] This utility model features a simple structure and automated control. In particular, the pure water machine is designed to be turned on and off solely by a high-pressure switch at the outlet. The water pressure at the outlet and the water volume in the storage tank are directly and quickly turned on and off through a controller and solenoid valve structure. This allows the entire device to achieve efficient and direct control through a simple mechanical structure, greatly reducing the workload of operators. Especially in situations requiring long-term sterilization, real-time monitoring by operators is not required, achieving the effect of low-cost automated control. Attached Figure Description

[0024] like Figure 1-6 As shown, a sterilization device 10 with self-generated pure water function is disclosed. The sterilization device 10 includes at least a sterilizer 1, a water storage tank 2, and a pure water machine 3. The inlet 21 of the water storage tank 2 is connected to the outlet 31 of the pure water machine 3 through a first pipeline 4. The first pipeline 4 forms a U-shaped path between the outlet 31 of the pure water machine 3 and the inlet 21 of the water storage tank 2. The first solenoid valve 51 is located in the lower middle or bottom of the U-shaped path. The outlet 31 of the pure water machine 3 is higher than the inlet 21 of the water storage tank 2.

[0025] The water outlet 23 of the water storage tank 2 is connected to the sterilizer 1 via the second pipeline 22, and also includes a first solenoid valve 51, a second solenoid valve 52, a water level gauge 7 and a controller 8.

[0026] The first solenoid valve 51 is used to controllably open or close the first pipeline 4; the solenoid valve 52 is used to controllably open or close the second pipeline 22.

[0027] The water level gauge 7 is installed inside the water storage tank 2 and is used to detect the real-time water level in the water storage tank 2 and send it to the controller 8; in this embodiment, a float water level gauge 7 (float-type water level gauge 7) is used, which has only one high water level threshold (third threshold), such as Figure 3 As shown, in this embodiment, its float 71 is located at Figure 3 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 indicates that the water level is lower than the high water level threshold.

[0028] The controller 8 is used to receive signal data from the water level gauge 7 and control the opening and closing of the first solenoid valve 51. It is further used to open the first solenoid valve 51 to connect the first pipeline 4 when the water level in the water storage tank 2 is lower than the high water level threshold (third threshold) and close the first solenoid valve 51 to close the first pipeline 4 when the water level is higher than the high water level threshold (third threshold).

[0029] The water purifier 3 outlet 31 is equipped with a high-pressure switch 6, which is used to measure the real-time water pressure in the outlet 31 and send it to the control center of the water purifier 3. The high-pressure switch 6 is used to close the high-pressure switch 6 when the real-time water pressure in the outlet 31 of the water purifier 3 rises and triggers a first threshold, and to open the high-pressure switch 6 when the water pressure falls and triggers a second threshold.

[0030] This embodiment further includes a second solenoid valve 52, which is located at the outlet 23 of the water storage tank 2. It is connected to the sterilizer through the second pipeline 22 and is used to open or close the outlet 23 of the water storage tank 2 under the control of the controller 8. The controller 8 is further used to receive data from the sterilizer 1 to control the opening or closing of the second solenoid valve 52.

[0031] like Figure 1 As shown in this embodiment, the sterilizer 1, water tank 2, and pure water machine 3 of the sterilization equipment 10 are designed in a modular manner. In particular, the sterilizer 1 and water tank 2 are designed as the same module, that is, the water tank 2 is directly designed on the outside of the sterilizer 1 to form a modular design, while the pure water machine 3 is designed in a modular manner as an external connection. This design is conducive to the flexible use of different models of pure water machines 3 and to the updating and maintenance.

[0032] In this embodiment, the outlet 23 of the water storage tank 2 is located at the bottom of the sterilizer 1, and the inlet 21 of the water storage tank 2 is located at the high position of the water storage tank 2. That is, pure water required for the sterilization process is injected from the bottom of the sterilizer 1 for high-temperature evaporation to achieve sterilization. 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 achieve pure water output from the water storage tank 2 to the sterilizer 1.

[0033] When the device is powered on, the water purifier 3 starts working. Assuming there is pressure in the tap water source, it begins producing pure water. The pure water travels through the first pipeline 4 (with the first solenoid valve 51 open) to the storage tank 2, where it begins storing pure water for sterilization. When the water level in the storage tank 2 exceeds the high water level threshold, indicating that the tank is full, the controller 8 closes the first solenoid valve 51, closing the first pipeline 4. After the first solenoid valve 51 closes, the water pressure in the first pipeline from the first solenoid valve 51 to the outlet 31 of the water purifier 3 begins to rise. When the pressure rises to a set value, i.e., when the real-time water pressure rise at the outlet 31 of the water purifier 3 triggers the first threshold, the high-pressure switch 6 of the water purifier 3 is turned off. In this embodiment, the design is such that when the high-pressure switch 6 is turned off, the water purifier 3 is simultaneously turned off, and the water purifier 3 stops working and enters a standby state. In this embodiment, the first threshold is generally set to 0.25±0.05MPa, meaning that when the water pressure rises from 0 to 0.25±0.05MPa, the high-pressure switch 6 is turned off, and the water purifier 3 stops working.

[0034] When sterilizer 1 needs water, the second solenoid valve 52 opens, and pure water in water storage tank 2 begins to flow into sterilizer 1 through the second solenoid valve 52. At this time, the water level in water storage tank 2 begins to drop. When the water level in water storage tank 2 is lower than the high water level threshold (third threshold), the first solenoid valve 51 opens to connect the first pipeline 4. The remaining pure water in the first pipeline flows into water storage tank 2, and the pressure in the first pipeline drops. When the pressure drops to the set value, that is, when the real-time water pressure drop process in the outlet 31 of the pure water machine 3 triggers the fourth threshold, the high-pressure switch 6 of the pure water machine 3 is opened. In this embodiment, it is designed that the pure water machine 3 is turned on at the same time when the high-pressure switch 6 is turned on, and the pure water machine 3 starts to work. In this embodiment, the fourth threshold is set to 0.15±0.05MPa, that is, when the water pressure drops to 0.15±0.05MPa, the high-pressure switch 6 is turned on, the pure water machine 3 works to produce pure water and continuously transmits it to water storage tank 2 through the first pipeline. At this time, the controller controls the water flow through the first solenoid valve to be less than the water flow through the second solenoid valve, so as to ensure that the water flow entering the water tank is less than the water flow out of the water tank, thereby ensuring that the water level in the water tank can remain below the high water level threshold for a certain period of time until the sterilizer 1 has enough water and then the second solenoid valve 52 is closed. Only when the pure water continuously enters the water tank can the float level gauge 7 return to above the high water level threshold, so that the float 71 is in the lower position B for a continuous time, avoiding the frequent up and down switching of the float 71 of the float level gauge 7, and reducing the frequency of repeatedly opening and closing the first solenoid valve;

[0035] Once the sterilization water reaches the preset volume in sterilizer 1, the second solenoid valve 52 closes, stopping water intake. Water tank 2 continues to fill until the water level reaches the high water level threshold, at which point the water purifier 3 stops working. Depending on usage, the automatic pure water production and supply processes are repeated.

[0036] In some embodiments, the water level gauge can be configured with a fourth threshold (low water level) and a fifth threshold (high water level), wherein the fourth threshold is less than the fifth threshold, and when the water level is lower than the fourth threshold, the first solenoid valve is opened to connect the first pipeline, and when the water level is higher than the fifth threshold, the first solenoid valve is closed to close the first pipeline.

[0037] 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.
