[0002] Hazardous gas detectors are specialized safety and health instruments used to detect flammable or toxic gases and vapors in chemical workplaces or equipment, and to generate alarms if these levels exceed limits. Other instruments include oxygen depletion detectors.

[0003] Conventional harmful gas detectors are generally handheld when in use, but due to different usage scenarios, they may be dropped while being held, causing the instrument to fall and be damaged. The lack of structural stability and a certain degree of structural protection makes the service life of the detector relatively limited.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a harmful gas detector with multiple detection heads is proposed. Utility Model Content

[0005] The purpose of the present utility model is to provide a harmful gas detector with multiple detection heads to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a harmful gas detector with multiple detection heads, comprising a detector assembly and an auxiliary gripping block, the lower end of the detector assembly being sleeved with an external pump assembly, and the side of the external pump assembly away from the detector assembly being connected to a sampling hose, the auxiliary gripping block being symmetrically installed on the bottom surface of the detector assembly, the auxiliary gripping block comprising a buffer block, an insert, a finger hole and an anti-slip cover, the top surface of the buffer block being symmetrically provided with inserts, and four groups of finger holes being arranged at the lower end of the buffer block, and anti-slip covers being installed inside the finger holes.

[0007] Furthermore, the detector assembly includes a detector host, gas sensing holes, a PM2.5 sensor, a carbon monoxide sensor, an ammonia sensor and an ozone sensor. The top end surface of the detector host is arrayed with four groups of gas sensing holes, and the PM2.5 sensor, carbon monoxide sensor, ammonia sensor and ozone sensor are respectively installed inside the four groups of gas sensing holes.

[0008] Furthermore, the detector assembly also includes a protective shell, a docking groove and an anti-slip strip. The outside of the detector host is connected to the protective shell, and the bottom surface of the protective shell is provided with a docking groove, and anti-slip strips are installed on both sides of the protective shell.

[0009] Furthermore, the protective shell and the detector host support are arranged as an integrated structure, and the anti-slip strip is fixedly connected to the protective shell.

[0010] Furthermore, the external pump assembly includes an external sampling pump, a quick connector and a stabilizing sleeve. The output end of the external sampling pump is equipped with a quick connector, and one side of the quick connector is connected to the stabilizing sleeve.

[0011] Furthermore, both ends of the sampling hose are provided with a splicable structure, and one end of the sampling hose is inserted into the interior of the stabilizing sleeve and is connected and fixed to the external sampling pump through a quick connector.

[0012] Furthermore, the buffer block and the insert are arranged in an integrated structure, and both the buffer block and the insert are made of buffer material.

[0013] Furthermore, the inner surface structure of the docking groove matches the surface of one side of the buffer block connected to the inserting strip, and the anti-slip sleeve is embedded in the inner wall surface of the finger hole.

[0014] The utility model provides a harmful gas detector with multiple detection heads, which has the following beneficial effects:

[0015] 1. The present invention provides two sets of auxiliary gripping blocks symmetrically disposed on the bottom of the detector assembly. The symmetrically disposed inserts on the top surfaces of the buffer blocks are horizontally slidably inserted into the docking grooves provided on the bottom surface of the protective shell, thereby allowing the auxiliary gripping blocks to be quickly mounted on the bottom surface of the detector assembly. The aforementioned structure, on the one hand, cooperates with the finger holes arranged at the bottom ends of the buffer blocks, and anti-slip sleeves are fitted inside the finger holes, allowing fingers to be inserted into the holes, thereby ensuring that the user has sufficient stability and firmness when holding the entire instrument, reducing the possibility of the device falling out of the hand and being damaged during use, thereby ensuring the safety of the device. On the other hand, the structural detachability between the auxiliary gripping blocks and the detector assembly allows the user to insert the auxiliary gripping blocks into the corresponding side of the bottom of the detector assembly according to their dominant hand, thereby facilitating the insertion and fixation of the fingers of the dominant hand, thereby achieving a firm grip and convenient and flexible use. In addition, since the buffer blocks and inserts are made of cushioning material, combined with the use of the protective shell, a certain degree of fall protection can be provided to the detector host, thereby minimizing the risk of falling damage, thereby providing good structural protection.

[0016] 2. In the present invention, there are four groups of gas sensing holes arrayed on the top surface of the detector host, and PM2.5 sensor, carbon monoxide sensor, ammonia sensor and ozone sensor are installed inside the four groups of gas sensing holes respectively. The PM2.5 sensor adopts ASAIR Aosong-APM3000-PM2.5 sensor module, the carbon monoxide sensor adopts Haiman-C6000A001 carbon monoxide sensor module, the ammonia sensor adopts ME3-NH3 ammonia sensor module, and the ozone sensor adopts Kaiyuanke ZE25-O3 ozone sensor module. By using the above structure, the four types of gases in the gas can be detected at the same time. The components can be quickly detected to meet the needs of use in different scenarios, so as to ensure the flexibility and practicality of the detection. In addition, through the combined use of an external pump assembly and a sampling hose, the external sampling pump is connected to one end of the detector host with a gas sensing hole, and then the quick connector uses the sampling hose connected thereto to quickly transmit the detected gas to the inside of the gas sensing hole over a long distance, thereby realizing fast and convenient detection operation. At the same time, since the sampling hose itself has splicing properties, multiple sampling hoses can be connected end to end to extend the structure, so as to realize long-distance sampling, provide a certain degree of safety for users, and ensure the flexibility of the use of the device.
