Description

Technical Field

[0001] This invention relates to a cleanroom device, and more particularly to a cleanroom device with a capsule sterilizer. Background Technology

[0002] Cleanroom equipment includes items such as clean benches, ultra-clean benches, clean benches, biosafety cabinets, purification units, and cleanroom accessories, used for purifying, disinfecting, and sterilizing items and the environment. However, after these devices are used, some harmful microorganisms may remain inside, necessitating sterilization of the equipment itself.

[0003] The common sterilization method involves placing or installing sterilization devices in these cleanrooms. For example, the Chinese utility model patent disclosed in "A Sealed Biosafety Cabinet Capable of Hydrogen Peroxide Disinfection" (CN 211865056 U) places a hydrogen peroxide generator inside the biosafety cabinet, seals the work area, turns on the hydrogen peroxide generator, and then turns it off after a period of time. Once the hydrogen peroxide concentration is detected to be below a preset standard, the disinfection is complete. Another method involves installing the device itself, such as the Chinese utility model patent "Biosafety Cabinet with Hydrogen Peroxide Disinfection" (CN 214020860 U). This method places a hydrogen peroxide generator at the bottom of the biosafety cabinet, which is piped into the work area. When needed, the front window of the biosafety cabinet is closed before sterilization of the interior.

[0004] Both of the methods described above have a problem: the disinfection generator is only located in one position. Although there is airflow circulation within the working area, it cannot guarantee that the hydrogen peroxide concentration is the same in every corner. In some areas, dead corners, and especially in irregularly shaped chambers, disinfection and sterilization cannot be thoroughly achieved, creating safety hazards. Therefore, we need a more effective and convenient disinfection device that meets the needs of various cleanroom equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a cleanroom device with a capsule sterilizer. Through structural improvements, it breaks through the installation methods of the previous two sterilizers, making it flexible to use and easy to install, and better adaptable to the comprehensive and effective sterilization needs of different environments and equipment.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a cleanroom device with a capsule sterilizer, comprising a cleanroom device body, wherein the cleanroom device body is provided with a plurality of inlets communicating with the inner cavity of the device to be sterilized, the inlets being matched with an outer connecting ring on the shell of the capsule sterilizer to form a sterilization unit, and the position and number of the sterilization unit to be connected are selected according to the actual sterilization requirements, and the inlets where the sterilization unit is not provided are provided with interface plugs.

[0007] In the above technical solution, the capsule sterilizer includes a shell with a liquid chamber inside. One end of the shell is an atomizing head, and the other end is a display and control unit. An infusion strip is provided in the liquid chamber, which is immersed in the disinfectant solution poured into the liquid chamber and absorbs the disinfectant solution. One end of the infusion strip is connected to the liquid supply port of the atomizing head. The disinfectant solution in the liquid chamber has a capacity sufficient to provide at least 180 minutes of continuous operation for the atomizing head, and the sterilization space is a closed space of 1 cubic meter to 2 cubic meters.

[0008] In the above technical solution, the housing is composed of left and right outer shells that are inserted into each other, and an outer connecting ring is provided on the outer edge of the housing, which is connected to the corresponding interface on the device.

[0009] In the above technical solution, the liquid chamber is a can-shaped container with one open end. The open end is provided with an external thread, and an end cap base is provided at the corresponding external thread for threaded connection. An infusion port is provided on the end cap base, and the infusion strip passes through the infusion port and is connected to the nebulizer head.

[0010] A further technical solution is that the outer side of the end cap base is provided with a recessed installation platform, the atomizing head is fixed on the installation platform, the end of the infusion strip is provided with a connecting seat, the connecting seat is inserted into the infusion port, and the connection is sealed.

[0011] In the above technical solution, the infusion strip is a porous absorbent cotton swab or a hemp fiber swab.

[0012] In the above technical solution, the display control unit includes a control chip, a battery, and a timer. The digital display screen of the timer is disposed on the outer end face of the housing. The outer end face is also provided with a switch and a charging interface. The switch outputs a signal to the control chip, and the control chip drives the signal to the atomizing head to start the atomizing head and the timer.

[0013] In the above technical solution, the control chip is equipped with a wireless communication circuit to receive and send wireless signals to the mobile terminal.

[0014] In the above technical solution, each of the inlets is provided with a sealing interface. The middle of the sealing interface is a mounting hole that communicates with the inner cavity of the main body. Its inner end is inserted into the inlet, and its outer end is provided with a fixing flange. The flange is sealed to the surface of the clean equipment body. The inner wall of the mounting hole is provided with threads, and the outer connecting ring of the sterilization unit is provided with external threads. The two are connected by threads.

[0015] In the above technical solution, the inlet is located on the outer wall of the operating chamber or on the pipe wall of the circulating air duct, as well as in places where disinfection is required but the space is small and there is no power supply.

[0016] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0017] 1. In this invention, a single capsule sterilizer can continuously sterilize for >180 minutes by injecting liquid (about 30ml) into the liquid chamber, meeting the requirement of conventional sterilization <120 minutes. Through the processing of the atomizing head, the sterilization range can reach a space of 1.5 to 2 cubic meters, and the killing effect on thermophilic stearobacter spores reaches Log6. It is small in size, has its own power supply, and can be used in confined spaces and areas without power supply (such as ceiling spaces, circulating air ducts, etc.) to be sterilized.

[0018] 2. To meet sterilization requirements, multiple capsule sterilizers can be arranged at multiple points for flexible drug administration, eliminating sterilization dead spots. Compared with previous overall sterilization equipment, this invention can be used in combination or separately, allowing for flexible switching between overall and local sterilization, quantitative sterilization, and reducing the harm of residues to the human body. At the same time, if a single unit fails, it will not cause the overall chamber sterilization to fail, demonstrating good fault tolerance.

[0019] 3. Each capsule sterilizer is equipped with a control unit that reflects the sterilization operation status in real time. It can be connected to a mobile terminal via a wireless communication circuit to receive and send the working status in real time. It can also realize the network operation of multiple capsule sterilizers through the mobile terminal, realizing intelligent one-button operation.

[0020] 4. The capsule sterilizer shell is composed of left and right outer shells that are inserted together. The medicine chamber can be opened. After a single sterilization is completed, the infusion stick can be replaced, the whole unit can be cleaned, and new medicine can be injected for reuse, which effectively controls its usage cost.

[0021] 5. This invention is small in size, more adaptable to different scenarios, and is green and energy-saving. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] Example 1: See Figures 1-6 As shown, a capsule-type sterilizer includes a housing 1 with a liquid chamber 2 inside. One end of the housing 1 is an atomizing head 3, and the other end is a display and control unit 4. An infusion strip 5 is provided inside the liquid chamber 2, which is immersed in the sterilizing solution poured into the liquid chamber 2 and absorbs the sterilizing solution. One end of the infusion strip 5 is connected to the liquid supply port of the atomizing head 3. The sterilizing solution in the liquid chamber 2 has a capacity sufficient to provide at least 180 minutes of continuous operation for the atomizing head 3. The sterilization space is a closed space of 1 to 2 cubic meters. In this embodiment, the capacity of the liquid chamber 2 is 30 ml, and the sterilizing solution is hydrogen peroxide sterilization solution.

[0032] like Figure 3 As shown, the housing 1 is composed of left and right outer shells that are inserted into each other. An outer connecting ring 6 is provided on the outer edge of the housing 1. The outer connecting ring 6 is connected to the corresponding interface on the device. The connection can be made by thread or by snap-fit.

[0033] The medication chamber 2 is a can-shaped tube open at one end, with an external thread at the open end. A cap base 7, threadedly connected to this thread, is located at the corresponding external thread. An infusion port is provided on the cap base 7, through which the infusion strip 5 passes and connects to the nebulizer head 3. A recessed mounting platform is provided on the outer side of the cap base 7, on which the nebulizer head 3 is mounted. A connecting seat 8 is provided at the end of the infusion strip 5, which is inserted into the infusion port and sealed in a tight fit. The infusion strip 5 is a porous absorbent cotton swab or hemp fiber swab, used to absorb the medication and introduce it into the nebulizer head 3, similar to the infusion method of a liquid pen. The infusion strip 5 is not limited to cotton swabs or hemp fiber swabs; any porous absorbent material will suffice. The infusion strip 5 is a consumable and needs to be replaced after each infusion.

[0034] In this embodiment, the atomizing head 3 can adopt an existing ultrasonic atomizer. It should be emphasized that its material has antioxidant properties (meeting the requirements of clean equipment) and uses a microporous atomizing sheet. The liquid medicine stock in the liquid medicine chamber 2 can be directly observed by opening the outer shell. Each sterilization consumes part (or all) of the liquid medicine, and the remaining liquid medicine is discarded and not reused.

[0035] As Figure 2-3 shown, the display control unit 4 includes a control chip, a storage battery 9 and a timer 10. The digital display screen of the timer 10 is arranged on the outer end face of the housing 1. A switch 11 and a charging interface 12 are also arranged on the outer end face. The switch 11 outputs a signal to the control chip, and the control chip sends a driving signal to the atomizing head 3 to start the atomizing head 3 and the timer 10. A wireless communication circuit is arranged in the control chip to receive and send wireless signals to the mobile terminal.

[0036] During use, a control program is pre-stored in the control chip, and the continuous working time range can be set. It will automatically stop after exceeding the range to avoid the liquid medicine being burned dry. After configuring the wireless communication circuit, such as Bluetooth, the working condition of the disinfection device can be observed and controlled in real time through a mobile terminal (such as a mobile phone APP). When applied to the equipment, multiple unit components can be connected through a wireless signal network and uniformly controlled by the mobile terminal for operation, detection, maintenance, etc., to achieve multi-point linkage and intelligent networking sterilization.

[0037] Specifically, as Figure 6 shown, a clean equipment with a capsule-type disinfection device includes a clean equipment body 13. A plurality of access ports communicating with the inner cavity of the equipment to be disinfected are arranged on the clean equipment body 13. A sealing interface 14 is arranged on each access port. The sealing interface 14 matches the outer connection ring 6 on the capsule-type disinfection device housing to form a sterilization unit body 17. According to the actual disinfection requirements, the position and quantity of the sterilization unit body 17 to be connected are selected. An interface plug 15 is arranged on the sealing interface 14 where the sterilization unit body is not set, as Figure 5 shown.

[0038] As Figure 4 shown, the middle of the sealing interface 14 is an installation hole communicating with the inner cavity of the body. Its inner end is inserted into the access port, and a fixing flange 16 is arranged at the outer end. The flange 16 is hermetically connected to the surface of the clean equipment body 13. Threads are arranged on the inner wall of the installation hole, and external threads are arranged on the outer connection ring 6 of the capsule-type disinfection device. The two are connected by threads.

[0039] According to the sterilization requirements, reasonably arrange the position and quantity of the disinfection devices. As Figure 5As shown, in this irregularly shaped working chamber, sterilization unit 17 is set at the top and middle of the chamber respectively. A sterilization unit 17 can also be placed in the air duct below the operating platform to eliminate sterilization dead corners and achieve the best sterilization effect.

[0040] Example 2: Figure 7 As shown, a cleanroom device with a capsule sterilizer includes a cleanroom device body. In this embodiment, the cleanroom device body is an air duct 18. Several inlets communicating with the inner cavity of the air duct 18 are provided at specific positions. Each inlet is provided with a sealing interface 14. The sealing interface 14 matches the outer connecting ring on the capsule sterilizer shell to form a sterilization unit 17. The position and number of sterilization units 17 are selected according to the actual sterilization requirements. The sealing interfaces 14 where no sterilization unit 17 is provided are provided with interface plugs.

[0041] In this embodiment, the sterilization unit 17 has a similar structure to that in Embodiment 1. It is located within the connected duct 18, where there is no power supply and the space is narrow. Therefore, in such environments, areas that traditional large, integrated sterilizers cannot reach or access, becoming sterilization dead zones, can be overcome by using the sterilization unit 17 in this embodiment. It is small in size, has its own power supply, can be deployed in multiple locations, and features intelligent network sterilization, achieving optimal sterilization results.
