Description

Technical Field

[0001] This utility model belongs to the field of gas safety monitoring technology, and in particular relates to a modular pump-suction portable gas detection device. Background Technology

[0002] Currently, portable gas detectors on the market are divided into diffusion type and portable type. These detectors detect gases in the environment by reacting with internal sensors through passive or active means, thus triggering detection and alarms. However, in environments with high levels of dust or moisture, gas detectors are prone to pump blockage, leading to inaccurate gas detection, failure to issue timely alarms, and potentially resulting in personal injury or death. Utility Model Content

[0003] In view of this, the present invention aims to propose a modular pump-suction portable gas detection device to solve the problem of pump blockage that is common in existing portable gas detectors.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a modular pump-suction portable gas detection device, comprising a housing assembly, a display integrated circuit board, a sensor integrated circuit board, and an air pump circuit board assembly. The housing assembly includes a front housing and a rear housing, which are connected by screws. The front housing has an air inlet. The display integrated circuit board, the sensor integrated circuit board, and the air pump circuit board assembly are all installed inside the housing assembly by screws. The display integrated circuit board is connected to a display screen, which is embedded in the front housing. The sensor integrated circuit board is equipped with various gas sensors and a buzzer. The air pump circuit board assembly is connected to an air pump module. The display integrated circuit board is connected to the air pump circuit board assembly via pins. The air pump module is connected to the sensor integrated circuit board, which is located between the air pump circuit board assembly and the air inlet.

[0005] Furthermore, the air pump module includes an air pump and an air pump sleeve module, through which the air pump is connected to the air pump circuit board assembly.

[0006] Furthermore, the housing assembly is fitted with a switch button, a detection button, an operation button, and an SOS button using sealant.

[0007] Furthermore, the front housing is equipped with a power switch and an operation button, while the rear housing is equipped with a detection button and an SOS button.

[0008] Furthermore, the switch button is located on the upper part of the front housing, the operation button is located on the lower part of the front housing, the SOS button is located on the back of the rear housing, and the detection button is located on the side of the housing assembly.

[0009] Furthermore, the rear housing is provided with a rear cover and a battery compartment. The rear cover is detachably connected to the rear housing. The rear cover is located at the air pump module. The battery compartment contains a battery. The rear side of the battery compartment is provided with a battery cover connected to the rear housing.

[0010] Furthermore, the rear cover is connected to the rear housing by screws, and one side of the battery cover is hinged to the rear housing, while the other side is fastened to the rear housing.

[0011] Furthermore, a charging port and a SIM card slot are respectively provided on both sides of the rear housing. Both the charging port and the SIM card slot are provided with rubber caps, which are fixed to the rear housing by rubber elastic plugs.

[0012] Furthermore, the housing assembly is provided with a buzzer sound hole, and the buzzer sound hole corresponds to the position of the buzzer.

[0013] Furthermore, each of the various gas sensors is provided with a sensor cover on its outer side.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a modular air pump structure and optimized gas path to achieve long-distance remote gas sampling, detection, and alarm functions through both diffusion and pumping methods. Especially in harsh environments with high dust and moisture content, the air pump can be quickly replaced for efficient and accurate gas detection.

[0015] This invention employs both diffusion and pump-suction gas sampling methods, and utilizes a pump module structure to allow for pump replacement or removal. If pump-suction gas sampling is not required on-site, a pump-free product series can be customized, reducing costs. If pump blockage occurs at the gas detection site, operators can quickly replace the pump, reducing both operation time and maintenance costs.

[0016] This invention optimizes the internal gas path structure of the product by placing the sensor on the upper part of the device, adjacent to the air inlet pipe. When the air pump is working, the sampled gas passes through the sensor first under the action of air pressure, instead of passing through the air pump and other components first, which shortens the gas sampling time and path and accelerates the sensor's response efficiency.

[0017] The button layout of this utility model conforms to the operating habits of on-site operators. The power switch is located on the top of the device, which will prevent accidental shutdown caused by personnel touching it. The detection button is located on the side of the device, which switches between diffusion and pumping functions and is used less frequently. The SOS button is located on the back of the device. When the operator holds the device to perform gas detection, the index finger is placed on the SOS button. In case of danger, the SOS button can be pressed at any time to issue an alarm.

[0018] This invention employs a large-screen display that flashes to indicate an alarm, providing a brighter and more noticeable warning compared to alarm lights. It also features a clasp-and-open battery cover for easy battery replacement, reducing charging time. Attached Figure Description

[0024] like Figures 1 to 7As shown, the main structure of this modular pump-suction portable gas detection device consists of a housing assembly, a display integrated circuit board 11, a sensor integrated circuit board 12, and a gas pump circuit board assembly 13. The housing assembly includes a front housing 1 and a rear housing 3, which are tightly connected by screws. The front housing 1 has an air inlet for gas to enter the detection channel.
