Description

Technical Field

[0001] This utility model relates to the field of ozone detection technology, and in particular to a portable ozone detection device. Background Technology

[0002] Portable ozone detection devices are small instruments used for the rapid and convenient detection of ozone concentration in the environment. They are widely used in indoor air monitoring, industrial site inspections, and environmental enforcement. There are several detection principles, including electrochemical and ultraviolet absorption methods. Electrochemical devices are more suitable for portable use due to their small size and low cost. Existing portable ozone detection devices often rely on clips to attach to the user's clothing for portability.

[0003] Current portable ozone detection devices mostly employ an integrated or fixed design for their clamping components, which presents several significant drawbacks during use. From a component damage perspective, the clamping component is where stress and wear are most concentrated during use. In daily carrying, the device may experience deformation or cracking due to collisions or drops, decreased spring elasticity over time, or rust after water ingress. The integrated or fixed design makes it difficult to replace a damaged clamping component individually. Furthermore, because the clamping component is tightly connected to the main body, even localized cracks, aging, or loosening cannot be easily disassembled and replaced; repair requires sending the entire device to a professional, resulting in significant time wastage and high maintenance costs. What could be a small component issue can escalate into a costly disassembly and repair. In addition, if damage to the clamping component is not addressed promptly, it can affect the device's clamping stability, increasing the risk of slippage during carrying and potentially damaging other core components (such as sensors and displays) or even leading to the device's loss. Therefore, those skilled in the art have provided a portable ozone detection device to address the problems mentioned in the background section. Utility Model Content

[0021] 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.

[0022] Reference Figure 6 An embodiment of this utility model is provided: a portable ozone detection device, including a clamping pad 4, a square tenon 13 fixedly provided at the front end of the clamping pad 4, a round tenon 8 fixedly provided at the front end of the square tenon 13, and two anti-detachment grooves 12 provided at the lower end of the round tenon 8.

[0023] Specifically, the clamping mechanism of this utility model mainly consists of a clamping piece 3 and a clamping pad 4. The clamping piece 3 works with the device body to clamp clothing and belts, enabling them to be carried around. The square tenon 13 and round tenon 8 on the clamping pad 4 are used to fix the clamping mechanism to the device. The anti-detachment groove 12 is used in conjunction with other components to prevent the clamping mechanism from accidentally falling off.

[0024] Reference Figures 1-7 The front end of the clamping pad 4 is tightly attached to the outer shell 1 of the equipment. The rear end of the clamping pad 4 is hinged with a clamping piece 3 by a torsion spring. The rear end of the outer shell 1 is provided with a slot 11. The upper part of the inner side of the outer shell 1 is provided with two rocker arm movable cavities 7. Rocker arms 5 are rotatably provided in both rocker arm movable cavities 7. Rocker hooks 9 are provided at the lower ends of both rocker arms 5. The upper end surfaces of the two rocker hooks 9 are respectively in contact with the lower end surfaces of the two anti-detachment slots 12. A return spring 6 is connected between the two rocker arms 5. A spring cavity 10 is provided in the inner side of the outer shell 1, adjacent to the upper part of the rocker arm movable cavity 7. The return spring 6 is movably provided in the spring cavity 10. A filter screen 2 is fixedly provided on one side of the outer shell 1.

[0025] Specifically, the clamping pad 4 and the clamping piece 3 are connected by a torsion spring for clamping. After the gripping clamping mechanism inserts the square latch 13 and the round latch 8 into the slot 11 and lifts upwards, the round latch 8 will push open the rocker hook 9 located in the rocker arm movable cavity 7. Finally, after being lifted to the end point, the square latch 13 and the square hole on the slot 11 fit together, which can effectively prevent the clamping mechanism from rotating and ensure the stability of the clamping mechanism. At the lower end of the round latch 8, the anti-disengagement slot 12 is hooked by the rocker hook 9 to prevent the clamping mechanism from slipping. The rocker hook 9 is initially pushed into the rocker arm movable cavity 7 by the round latch 8. Later, the elastic force from the return spring 6 on the rocker arm 5 returns it to its original position, hooking back into the round latch 8. When you want to replace the clamping mechanism, simply apply a force towards the middle of the two rocker arms 5. The rocker hook 9 will then return to the rocker arm movable cavity 7 as the rocker arms 5 move. At this point, applying a downward force to the clamping mechanism will remove it. This process is convenient, quick, simple, requires no repairs, is time-efficient, and economical. The electronic components contained within the outer casing 1 include an ozone detection sensor, an operational amplifier, a signal converter, a microcontroller, a display screen, a battery, and buttons. These components are connected via a PCB circuit board. Since the system utilizes widely adopted and mature technologies, its operation and principles are well-known to those skilled in the art, and therefore require no further explanation through modeling. When the user uses this invention, the device is opened and clipped to clothing. Ozone-containing air flows into the device through the filter 2, then comes into contact with the ozone detection sensor. A chemical reaction occurs with the electrolyte on the sensor surface, generating a weak current proportional to the ozone concentration. This weak current is conducted to the operational amplifier, amplified into a processable electrical signal, transmitted to the signal converter, converted into a digital signal, and then transmitted to the microcontroller. The microcontroller calculates the actual ozone concentration based on a built-in algorithm and finally transmits the data to the display screen for intuitive presentation. During operation, the battery provides power to the components, and the buttons are used to control operation and power on / off.

[0026] Working principle: The clamping mechanism consists of clamping plates 3 and clamping pads 4 connected by a torsion spring. Clamping plates 3, in conjunction with the device body, can clamp clothing and belts for convenient carrying. During installation, the square latch 13 and round latch 8 on the clamping pad 4 are inserted into the slot 11 and lifted. The round latch 8 pushes open the rocker hook 9 in the rocker arm's movable cavity 7. After reaching the end point, the square latch 13 engages with the square hole in the slot 11 to prevent rotation of the clamping mechanism. The anti-disengagement groove 12 at the lower end of the round latch 8 is hooked by the rocker hook 9, which is reset by the return spring 6, to prevent it from falling off, ensuring stability. When replacing the clamping mechanism... Press the two rocker arms 5 in the middle to retract the rocker hook 9 into the rocker movable cavity 7, and then pull down to remove the clamping mechanism. The use and disassembly of the clamping mechanism are very convenient. When the clamping device is damaged, there is no need to send it for repair, which greatly reduces the cost of money and time. When the equipment is working, ozone-containing air enters through the filter 2. The ozone reacts with the sensor to generate a proportional weak current. After being amplified by the operational amplifier and converted into a digital signal by the signal converter, the concentration is calculated by the controller according to the algorithm and displayed on the screen. The equipment components are powered by batteries, and the operation and power on / off are controlled by buttons.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
