Description

Technical Field

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

[0002] A gas detector is an instrument used to detect gas leak concentrations, including portable gas detectors, handheld gas detectors, stationary gas detectors, and online gas detectors. It primarily utilizes gas sensors to detect the types of gases present in the environment; gas sensors are used to detect the composition and concentration of gases.

[0003] Chinese patent CN214668908U discloses a portable gas concentration detection device. This patent describes a method for measuring gas concentration at a height: opening the upper housing 110 and lower housing 120, extending the telescopic rod 500, and elongating the entire self-priming gas detector 100. While this structure can achieve gas concentration detection, the overall weight is concentrated on the upper housing when it is extended. When lifted to measure gas concentration at a height, the center of gravity is at the top, making it prone to tipping over and damaging the device. Furthermore, this device cannot detect gas inside high-altitude turning spaces, limiting its application scenarios. Utility Model Content

[0004] In order to overcome the existing technical defects, the purpose of this utility model is to provide a portable gas concentration detection device to solve the above-mentioned technical problems.

[0005] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0006] According to one aspect of this utility model, a portable gas concentration detection device is designed, comprising: a self-priming gas detector, a gas delivery hose, a metal ball, a universal tube, and a rigid gas delivery tube composed of multiple detachably connected rigid tubes. One end of the gas delivery hose and one end of the rigid gas delivery tube are detachably connected to the air inlet of the self-priming gas detector, respectively. The other end of the gas delivery hose is connected to a connector on the metal ball, and the other end of the rigid gas delivery tube is detachably connected to the universal tube. The metal ball is hollow, and a plurality of air inlet holes are distributed on the end with the connector.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, a filter is also included, wherein the air outlet of the filter is threadedly connected to the air inlet of the self-priming gas detector, and the air inlet is threadedly connected or plugged into one end of the air guide hose and one end of the rigid air guide tube, respectively.

[0009] In some embodiments, sealing gaskets or O-rings are provided at the connection points between adjacent rigid tubes and between rigid tubes and universal joints.

[0010] In some embodiments, the outer surface of the metal ball is fixed with a filter screen covering all air inlets by screws.

[0011] In some embodiments, the self-priming gas detector is equipped with a display screen, multiple function buttons, and an alarm component.

[0012] In some embodiments, the filter includes an upper shell, a connecting shell threaded to the upper shell, a lower shell threaded to the lower end of the connecting shell, a dust removal layer disposed between the upper shell and the connecting shell, and a drying layer disposed between the connecting shell and the lower shell.

[0013] The beneficial effects of this application are:

[0014] After connecting the rigid air duct to the air inlet of the self-priming gas detector, the handheld self-priming gas detector can be used to detect gas concentrations at high altitudes. Compared to existing self-priming gas detectors that require the upper and lower shells to be stretched and held high for detection, the detection device in this application has a relatively lower height from the ground during detection, which greatly reduces the probability of falling and damage, and extends its service life. In addition, after connecting the universal tube to the air duct, the universal tube can be bent in any direction and inserted into the interior of high-altitude turning spaces to extract and detect the gas inside the turning space, improving its practicality.

A sealing gasket or O-ring is provided at the connection point between adjacent rigid tubes 51 to achieve a sealed connection. There are three, four, five, or more rigid tubes 51. The rigid tubes 51 are made of rigid plastic, aluminum, copper, stainless steel, etc., and their length is 25-40 cm.

[0024] The outlet of filter 6 is threadedly connected to the inlet port 10 on the self-priming gas detector 1. One end of the air guide hose 2 and one end of the rigid air guide tube 5 can be threadedly connected or plugged into the inlet port on the self-priming gas detector 1 and the air inlet of filter 6, respectively. In this embodiment, it is preferred that one end of the air guide hose 2 and one end of the rigid air guide tube 5 can be threadedly connected to the inlet port on the self-priming gas detector 1 and the air inlet of filter 6, respectively, and a sealing gasket or O-ring is provided at the connection position.

Its interior is connected to the interior of the metal ball 3. Several air inlets 32 are distributed on one end of the metal ball 3 with the connector 31. A filter screen covering all the air inlets 32 is fixed to the outer surface of the metal ball 3 by screws. The filter screen is hemispherical. The filter screen can perform the first filtration of the gas entering the metal ball 3 and remove large dust particles in the gas.

[0026] The other end of the rigid air guide tube 5 is threaded or plugged into the universal tube 4. In this embodiment, it is preferred that the other end of the rigid air guide tube 5 is threaded into the universal tube 4.

[0027] The filter 6 includes an upper shell 61, a connecting shell 62 threaded to the upper shell 61, a lower shell 63 threaded to the lower end of the connecting shell 62, a dust removal layer 64 located between the upper shell 61 and the connecting shell 62, and a drying layer 65 located between the connecting shell 62 and the lower shell 63. The dust removal layer 64 contains a sponge block, or the dust removal layer 64 is a sponge block. The drying layer 65 contains an air desiccant, or the drying layer 65 is a silica gel desiccant sponge or a moisture-absorbing sheet, etc. The threaded connection between the upper shell 61 and the connecting shell 62, and the threaded connection between the connecting shell 62 and the lower shell 63, facilitates the periodic replacement of the dust removal layer 64 and the drying layer 65, ensuring accurate detection. In addition, the dust removal layer 64 or the drying layer 65 can be removed separately, thereby meeting the gas detection needs in various scenarios. A sealing gasket is provided between the upper shell 61 and the connecting shell 62, and a sealing gasket is also provided between the connecting shell 62 and the lower shell 63.

The battery, gas detection sensor, self-priming pump, display screen, function buttons, and alarm component are electrically connected to the control circuit board.

[0029] When measuring gas concentration at a high altitude, connect the lower outlet connector (with external thread) of filter 6 to the inlet port (with internal thread) of the self-priming gas detector 1. Then, connect the lower end (with external thread) of rigid air guide tube 5 to the upper inlet connector (with internal thread) of filter 6, and the lower end (with external thread) of universal tube 4 to the upper end (with internal thread) of rigid air guide tube 5. Turn on the switch on the self-priming gas detector 1 to measure the gas concentration at a high altitude. Whether or not filter 6 is installed depends on the measurement requirements. If filter 6 is not needed, the lower end of rigid air guide tube 5 can be directly connected to the inlet port of the self-priming gas detector 1. After measurement, remove all components for storage. The threaded connection between multiple components reduces the storage length and facilitates storage.

[0030] When measuring narrow or curved pipes, assemble the filter 6, the air guide hose 2, and the metal ball 3 in sequence on the air inlet of the self-priming gas detector 1. Insert the metal ball 3 into the pipe to a certain depth. After the measurement is completed, pull the air guide hose 2 out of the pipe.
