Description

Technical Field

[0001] This utility model relates to the field of sterilizer technology, specifically a hydrogen peroxide gas sterilizer for laboratory use. Background Technology

[0002] With the development of hydrogen peroxide gas disinfection equipment, it has gained increasing recognition from some enterprises and its application scope has become wider. The environmental conditions of disinfection sites are also becoming more and more complex. Places with high humidity and low temperature, such as washing and disinfection rooms, also need to be disinfected regularly. The disinfection effect of using hydrogen peroxide gas disinfection equipment is not good. In order to meet this market demand, there is an urgent need to develop a hydrogen peroxide gas disinfection device that can automatically adjust the ambient temperature and humidity and is suitable for space disinfection and object surface disinfection in ordinary environments. At present, there are various types of hydrogen peroxide gas sterilizers for laboratory use on the market, but they still have some shortcomings.

[0003] Existing laboratory hydrogen peroxide gas sterilizers suffer from several drawbacks. They use compressed gas to atomize hydrogen peroxide, resulting in limited spatial spraying, long diffusion time within the sterilization space, and poor uniformity of distribution. Furthermore, when the temperature and humidity conditions within the sterilization space are unsuitable, external air conditioning or heating is required. For example, Chinese Utility Model Patent CN208877403U discloses an integrated hydrogen peroxide sterilizer. This utility model relates to a sterilizer comprising a housing, a flash metering device, and a diffusion device. The flash metering device includes a flash evaporator, a vaporization fan, a metering pump, and a storage tank. The diffusion device includes a diffusion fan fixed to the top of the housing and connected to the external environment, a diffusion connecting pipe, and a diffusion reversing valve for switching between the diffusion fan and the diffusion connecting pipe to allow hydrogen peroxide to pass through. The inlet of the vaporization fan is connected to a return air connecting pipe connected to the external environment. The first end of the diffusion reversing valve is connected to the diffusion fan via a pipe, the second end is connected to the outlet of the flash evaporator via a pipe, and the third end is connected to the diffusion connecting pipe via a pipe. However, this sterilizer uses high-temperature flash evaporation technology, which utilizes high-temperature vaporization of hydrogen peroxide. Since hydrogen peroxide decomposes violently at temperatures above 100 degrees Celsius, and the higher the temperature, the faster the decomposition rate, it can affect the humidity in the sterilization space to some extent. Therefore, we propose a laboratory hydrogen peroxide gas sterilizer to solve the problems mentioned above. Utility Model Content

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This laboratory hydrogen peroxide gas sterilizer is equipped with a temperature and humidity control mechanism that can automatically adjust the temperature and humidity of the sterilization space.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6 This utility model provides a technical solution:

[0034] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: A laboratory hydrogen peroxide gas sterilizer is provided with a housing 7, and a temperature and humidity detection unit 8 is located on the front left side of the diffusion unit 1. The temperature and humidity detection unit 8 includes a sampling fan 801 and a temperature and humidity sensor 802, with the temperature and humidity sensor 802 installed on the rear side of the sampling fan 801. A control cabinet 10 is located on the left side inside the diffusion unit 1. An automatic temperature and humidity adjustment mechanism for the sterilization space is located inside the housing 7 to regulate the air temperature and humidity within the sterilization space to meet the required temperature and humidity conditions for sterilization. A low-temperature evaporation mechanism is located inside the housing 7, utilizing an ultrasonic atomizing head 403 to generate particles with a diameter of approximately 5 μm. Hydrogen peroxide atomized particles are heated in dry air at a temperature not exceeding 50°C to ensure rapid evaporation of the hydrogen peroxide atomized particles into hydrogen peroxide gas, which diffuses into the disinfection space to achieve space disinfection. A rapid diffusion mechanism, located inside the outer casing 7, ensures full evaporation of hydrogen peroxide, generating hydrogen peroxide gas, which diffuses into the disinfection space via diffusion unit 1. The initial preparation stage is for equipment preheating and temperature and humidity adjustment of the disinfection space. This is achieved as follows: the double-position gate valve assembly 5 opens to connect the ventilation unit 2. Air in the disinfection space is dried by the ventilation fan 202, passing through the desiccant filter 601, and then heated by the temperature control unit 3. The temperature control unit 3 includes a temperature sensor 301 and a heating coil 302. Sensor 301 is connected to hydrogen peroxide concentration detector 204. The hydrogen peroxide is released into the disinfection space through diffusion unit 1, rapidly raising the humidity level to the required conditions for disinfection. Then, the programmed disinfection stage begins. To fill the disinfection space with a specific concentration of hydrogen peroxide gas for a designated time, hydrogen peroxide solution is added to atomization unit 4 via metering pump 904. The solution is atomized by ultrasonic atomizing head 403. The atomized hydrogen peroxide particles are preheated by temperature control unit 3 under the action of exhaust fan 101, ensuring the temperature does not exceed 50°C. This achieves initial evaporation of hydrogen peroxide while preventing excessive decomposition. The atomized particles then enter ventilation unit 2, where air is dried by desiccant filter 601. After being heated by the temperature control unit 3 and mixed with hydrogen peroxide mist particles in the ventilation unit 2, the hydrogen peroxide is fully volatilized, generating hydrogen peroxide gas. This gas is then diffused into the disinfection space via the diffusion unit 1. The ventilation stage of the program is to decompose the hydrogen peroxide gas in the disinfection space. The process involves the valve plate 501 of the double-position gate valve assembly 5 switching to connect the hydrogen peroxide decomposition filter 602 with the ventilation unit 2. The air mixed with hydrogen peroxide gas in the disinfection space is forced through the hydrogen peroxide decomposition filter 602 by the ventilation fan 202, decomposing the hydrogen peroxide gas. The gas is then diffused into the disinfection space via the diffusion unit 1 through the ventilation unit 2, thereby reducing the concentration of hydrogen peroxide gas in the disinfection space. When the concentration falls below a certain value, the program ends.

[0035] Existing sterilizers use high-temperature flash evaporation technology to vaporize hydrogen peroxide. However, hydrogen peroxide decomposes rapidly above 100 degrees Celsius, with the decomposition rate increasing at higher temperatures, which affects the humidity within the sterilization space. Therefore, this embodiment employs the following technical solution: Figure 4 , Figure 5 and Figure 6 As shown, the low-temperature evaporation mechanism includes a double-position gate valve assembly 5 located inside the lower part of the outer casing 7. The double-position gate valve assembly 5 is composed of a valve plate 501, a screw 502, a frame assembly 503, and a valve motor 504. Since the valve plate 501 is located inside the frame assembly 503, and the screw 502 is connected to the top of the valve plate 501, opening the valve motor 504 connected to the screw 502 will switch the valve plate 501 to connect with the lower hydrogen peroxide decomposition filter 602 and the ventilation unit 2, thereby rapidly decomposing the hydrogen peroxide gas in the disinfection space through circulating ventilation.

[0036] Example 2: Existing sterilizers, which use hydrogen peroxide atomization, have a strong spatial limitation in their spray, resulting in a long diffusion time within the sterilization space. Therefore, this example uses the following technical solution, such as... Figure 1 , Figure 2 and Figure 4 As shown, the rapid diffusion mechanism includes an atomizing unit 4 disposed inside the outer casing 7. Hydrogen peroxide solution is added to the atomizing unit 4 by a liquid inlet unit 9. The liquid inlet unit 9 is composed of a non-contact liquid level sensor 901, a liquid storage tank 902, a liquid storage tank body 903, and a metering pump 904. Adding hydrogen peroxide solution from the liquid storage tank body 903 and the liquid storage tank 902 into the atomizing unit 4 will generate hydrogen peroxide mist particles. The atomizing unit 4 is composed of a hydrogen peroxide inlet 401, a connecting flange weld 402, an ultrasonic atomizing head 403, and an atomizing head support 404. The connecting flange weld 402 is provided on the outside of the hydrogen peroxide inlet 401 for secure installation and fixation. An ultrasonic atomizing head 403 is installed below the liquid inlet 401, and an atomizing head bracket 404 is installed on the outside of the ultrasonic atomizing head 403 for support. The ultrasonic atomizing head 403 can atomize the hydrogen peroxide solution, which is then heated by the temperature control unit 3, which consists of a temperature sensor 301 and a heating coil 302. After being heated, the hydrogen peroxide solution can enter the ventilation unit 2. At the same time, the desiccant filter 601 is connected below the double-position gate valve assembly 5. The air in the ventilation unit 2 will be dried by the desiccant filter 601. After being preheated by the temperature control unit 3, the air mixes with the hydrogen peroxide mist particles in the ventilation unit 2, allowing the hydrogen peroxide to fully evaporate and generate hydrogen peroxide gas, which is then diffused into the disinfection space through the diffusion unit 1.

[0037] Example 3: Existing sterilizers often suffer from problems such as the need for external air conditioners or heaters when the temperature and humidity conditions within the sterilization space are insufficient for their operation. Therefore, this example addresses these issues through the following technical solution: Figure 1 , Figure 4 and Figure 5 As shown, the automatic temperature and humidity adjustment mechanism for the disinfection space includes a desiccant filter 601 located on the right side below the double-position gate valve assembly 5. A hydrogen peroxide decomposition filter 602 is located to the left of the desiccant filter 601. The hydrogen peroxide decomposition filter 602 and the desiccant filter 601 together constitute a filter unit 6. The air in the disinfection space is dried by the desiccant filter 601. The ventilation fan 202, which is supported by a ventilation box 201 connected to its outer side, is turned on, allowing air to pass through. The airflow inside the ventilation duct 203 will flow upwards, and the temperature will be raised by the temperature control unit 3. The temperature control unit 3 is composed of a temperature sensor 301 and a heating coil 302. The heating coil 302 is set on the outside of the air outlet duct 104. When the exhaust fan 101 is turned on, the air moves upwards from the air outlet duct 104. The fan bracket 103 is set on the outside of the air outlet duct 104 for support. The air diffuses into the disinfection space through the guide vane assembly 102, thereby regulating the temperature and humidity of the air in the disinfection space to meet the temperature and humidity conditions required for disinfection.
