Description

Technical Field

[0001] This utility model relates to a hydrogen peroxide evaporator with liquid level control, specifically to the field of disinfection equipment technology. Background Technology

[0002] Disinfection using hydrogen peroxide is a common method in daily production activities. When using it, a certain concentration of hydrogen peroxide solution is used for cold evaporation to form dry fog, which is then used to disinfect and sterilize the surface of objects. This is a relatively common disinfection method.

[0003] When using a disinfection machine, all operations are controlled by a microcomputer program, and the disinfection time and atomization volume are fixed. It needs to atomize a specific amount of disinfectant within a certain time to achieve the desired disinfection effect. The amount of disinfectant atomized in a hydrogen peroxide disinfection machine is injected into the evaporator tank each time by a metering pump. This metering pump is usually a peristaltic pump or a piston pump. If too much disinfectant is added, it will affect the atomization effect. Unatomized disinfectant will gradually accumulate and fill the atomization chamber, leading to equipment malfunction. Summary of the Invention

[0004] The purpose of this invention is to provide a hydrogen peroxide evaporator with liquid level control, which solves the problem that adding too much disinfectant will affect the atomization effect, and will gradually accumulate and fill the atomization chamber, leading to the failure of the disinfection equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hydrogen peroxide evaporator with liquid level control includes a dosing port (1), a drain pipe (2), a drain outlet (3), a liquid inlet (4), a liquid level sensor one (5), a liquid level sensor two (6), a liquid level detection window (7), a bubble exhaust port (8), and an evaporator (13).

[0007] The outer wall of the evaporator (13) is provided with a dosing port (1) leading to the inside of the tank. A soft drain tube (2) is fitted onto the dosing port (1). The other end of the drain tube (2) is connected to the drain outlet (3). The bottom center of the evaporator (13) is provided with a liquid inlet (4). Liquid level detection windows (7) are provided on both sides of the liquid inlet (4). Bubble exhaust ports (8) are connected to the liquid level detection windows (7). Liquid level sensor 1 (5) and liquid level sensor 2 (6) are connected to the bubble exhaust ports (8).

[0008] Furthermore, the side wall of the evaporator (13) is provided with a lead wire through hole (9), the liquid level sensor one (5) is connected with a liquid level sensor one lead wire (10), the liquid level sensor two (6) is connected with a liquid level sensor two lead wire (11), the liquid level sensor one lead wire (10) and the liquid level sensor two lead wire (11) pass through the lead wire through hole (9) and exit the evaporator (13).

[0009] Furthermore, the upper edge of the evaporator (13) is provided with a splash guard (12).

[0010] Furthermore, the drainage tube (2) is a silicone tube.

[0011] The beneficial effects of this utility model are as follows: This device, by installing level sensors 5 and 6 inside the evaporator 13, judges the liquid level, thereby ensuring a stable liquid level each time disinfectant is added. This further ensures a constant amount of disinfectant added. By ensuring a stable supply of disinfectant, the disinfection effect is guaranteed each time. By controlling the liquid level height, the amount of disinfectant in the evaporation chamber is ensured to be constant, without affecting the atomization effect. Simultaneously, the inlet 4 is designed at the bottom of the tank to ensure the stability of the disinfectant level rise in the evaporator 13 during dispensing, preventing it from flowing from other parts and avoiding unstable liquid level impact that could cause dispensing deviations, leading to unstable liquid levels and affecting the sensors.

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Please see Figure 1 An embodiment of this application shows a hydrogen peroxide evaporator with liquid level control, including a dosing port 1, a drain pipe 2, a drain outlet 3, a liquid inlet 4, a liquid level sensor 1 5, a liquid level sensor 2 6, a liquid level detection window 7, a bubble exhaust port 8, and an evaporator 13.

[0022] An inlet 1 leading to the inside of the tank is provided on the outer wall of the evaporator 13. A flexible drain tube 2 is fitted onto the inlet 1, and the other end of the drain tube 2 is connected to a drain outlet 3. An inlet 4 is provided at the center of the bottom of the evaporator 13. Liquid level detection windows 7 are provided on both sides of the inlet 4. Bubble venting ports 8 are connected to the liquid level detection windows 7. Liquid level sensor 1 5 and liquid level sensor 2 6 are connected to the bubble venting ports 8.

[0023] The side wall of the evaporator 13 is provided with a lead wire through hole 9. A lead wire 10 of the first liquid level sensor 5 is connected to the first liquid level sensor 5, and a lead wire 11 of the second liquid level sensor 6 is connected to the second liquid level sensor 6. The lead wires 10 of the first liquid level sensor and 11 of the second liquid level sensor pass through the lead wire through hole 9 and exit the evaporator 13.

[0024] The upper edge of the evaporator 13 is provided with a splash guard 12.

[0025] Drainage tube 2 is a silicone tube.

[0026] When in use, the machine is started, and the liquid level sensor 5 inside the atomizing tank 13 detects the liquid level at the bottom of the tank. Liquid level sensors 5 and 6 are capacitive proximity switches, and their sensitivity can be adjusted to detect the liquid level. When liquid level sensor 5 detects liquid at the bottom of the tank, the machine does not add liquid to the evaporator 13. When adding medication, liquid level sensor 5 does not detect liquid, so the machine continuously adds liquid to the evaporator 13. When liquid level sensor 5 detects liquid, the machine stops adding medication. Liquid level sensor 6 can be used as a safety liquid level sensor. When liquid level sensor 6 detects liquid, the machine can start other programs or trigger an alarm. The two liquid level sensors 5 and 6 are connected by threads at the bottom of the evaporator 13 and installed in the bottom area of ​​the evaporator 13. Liquid is poured into the tank through the liquid level detection window 7 to the level below liquid level sensor 5 or 6 to detect the liquid level. Level sensor lead 10 and level sensor lead 11 can be connected to the main control board via lead hole 9 on the side wall of evaporator 13 for signal transmission. Bubble vents 8 are located on both sides of level detection window 7. When the liquid level rises at the level sensor installation location, the bubble vents 8 can release air without affecting the liquid level at the bottom of evaporator 13 and inside level detection window 7.

[0027] In summary, this utility model provides a hydrogen peroxide evaporator with liquid level control. This device ensures a stable liquid level each time disinfectant is added by installing liquid level sensors 5 and 6 inside the evaporator 13 to judge the liquid level. This further ensures a constant amount of disinfectant added. By ensuring a stable supply of disinfectant, the disinfection effect is guaranteed each time. By controlling the liquid level height, the amount of disinfectant in the evaporation chamber is kept constant, without affecting the atomization effect. Simultaneously, the inlet 4 is designed at the bottom of the tank to ensure the stability of the disinfectant level rise in the evaporator 13 during dosing, preventing it from flowing from other parts and avoiding unstable liquid level impacts that could lead to quantitative deviations in dosing, causing instability and affecting the sensors.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
