[0025] 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.

[0026] As a key piece of equipment in laboratories, medical fields, and electronic manufacturing, ultra-clean workbenches are mainly used to provide a localized, dust-free, and sterile high-cleanliness operating environment to prevent microbial contamination or particulate impurities from affecting experimental samples, precision devices, etc.

[0027] Due to the technical deficiency of existing technology, which lacks an alarm function for cabinet door 6 not being closed, please refer to... Figures 1-6The clean bench with ozone detection function provided in this embodiment can remind staff to close the cabinet door 6, preventing dust from entering and contaminating the workbench due to prolonged periods without closing the door 6. The clean bench includes a cabinet 1 with a working chamber. Two sets of fans 2 are installed on the inner side of the top of the cabinet 1. A filter element 3 is located above the fans 2 and is movably inserted into the cabinet 1. A cabinet door 6 corresponding to the working chamber is movably located on the front of the cabinet 1. An alarm triggering component 9 is embedded in the bottom of the working chamber, directly below the cabinet door 6. An infrared sensor 10 and a buzzer 11 are embedded on the front of the cabinet 1 near the alarm triggering component 9. In these components, the fans 2 and the filter element 3 work together to actively introduce external air into the working chamber and achieve… The system filters components to ensure an ultra-clean working environment. Filter element 3 is installed on cabinet 1 via a movable plug-in connection, allowing for easy cleaning or replacement by simply pulling it out. The system also includes an alarm trigger assembly 9, an infrared sensor 10, and a buzzer 11. When cabinet door 6 is opened, contacts 95 and 96 in alarm trigger assembly 9 close, activating infrared sensor 10. This detects whether someone is in front of the workbench. If someone is present, buzzer 11 will not sound an alarm. After use, if the staff forgets to close cabinet door 6 after leaving the workbench, infrared sensor 10 will detect the absence of staff and trigger buzzer 11 to remind them to close cabinet door 6.

[0028] In actual use, after completing their work, staff may inadvertently forget to close cabinet door 6. Traditional equipment lacks an active alarm function and cannot promptly alert staff to the unclosed state of cabinet door 6, resulting in the workbench remaining in an unsealed state for extended periods, increasing the risk of contamination. For a solution to this problem, please refer to [link / reference needed]. Figure 6 The alarm triggering component 9 includes a housing 91 embedded in the bottom of the working chamber. A pin 92 is movably connected inside the housing 91. The top of the pin 92 extends to the outside of the housing 91, and a movable plate 93 is fixed at the bottom. The bottom of the movable plate 93 is elastically connected to the bottom of the housing 91 by a spring 94. A contact 95 is fixed at one end of the movable plate 93, and a contact 96 fixed inside the housing 91 is located above the contact 95. The contacts 95 and 96 are connected to the power circuit of the infrared sensor 10. When the glass cabinet door 6 is closed, the pin 92 is pressed, causing the contacts 95 and 96 to separate and disconnect the circuit of the infrared sensor 10. When the cabinet door 6 is opened, the pin 92 springs up, the contacts close, and the sensor is activated, ensuring that personnel activity is monitored only when the cabinet door 6 is open to avoid false triggering. When the cabinet door 6 is not closed, the alarm can be triggered.

[0029] Most existing filter elements 3 are installed on the cabinet 1 using bolts or similar methods. However, bolt installation and removal require tools, which is inconvenient. For a solution to this problem, please refer to... Figure 5Two sets of symmetrically arranged buckle assemblies 4 are fixed on the outer wall of the filter element 3. The buckle assembly 4 includes a fixing buckle 41 fixed to the outer wall of the filter element 3. A spring 42 is installed inside the fixing buckle 41. One end of the spring 42 is fixedly connected to a pin 43 movably connected inside the fixing buckle 41. A lever 44 is fixedly connected to the pin 43. The lever 44 is movably connected to a through hole opened on the fixing buckle 41. A latch 45 is inserted into one end of the pin 43. The latch 45 is fixed to the back of the cabinet 1. By moving the pin 43 with the lever 44, the fixing of the filter element 3 is released, so that the filter element 3 can be taken out. It has the advantage of simple operation.

[0030] Traditional clean benches lack ozone concentration monitoring, which can easily lead to personnel being exposed to high concentrations of ozone. To address this issue, ultraviolet disinfection lamps 7 and ozone concentration sensors 8 are installed on the inner wall of the working chamber. The ultraviolet disinfection lamps 7 can be used to disinfect the inside of the working chamber, and ozone will be generated during the disinfection process. The ozone concentration sensor 8 monitors the ozone concentration inside the working chamber. When the concentration is high, the cabinet door 6 can be opened in time for ventilation to dissipate the ozone.

[0031] Furthermore, a switch panel 13 is embedded on the front of the cabinet 1 to facilitate the control of the operation of various electrical components on the cabinet 1.

[0032] Traditional clean benches either lack seating or use fixed seating, occupying space in the clean area and affecting operational flexibility. To address this issue, please refer to... Figure 1 and Figure 2 A folding stool assembly 12 is provided at the bottom of the front of the cabinet 1. The folding stool assembly 12 includes a stool body 121 rotatably connected to the bottom of the cabinet 1 and two fixing blocks 122 fixed to the bottom of the cabinet 1. Fixing pins 123 are movably connected to the fixing blocks 122 and are inserted into fixing holes opened on the stool body 121. The stool body 121 can be folded and stored at the bottom of the cabinet 1. When not in use, it fits against the cabinet 1, saving floor space in the clean area. When the stool body 121 is opened, it provides a temporary seat, which is suitable for long-term fine operation, reduces personnel fatigue, and improves work efficiency.

[0033] Furthermore, a grid 5 fixed to the cabinet 1 is provided above the filter element 3 and below the fan 2 to protect the filter element 3 and the fan 2.
