[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The purpose of this invention is to provide a gas detector to solve the problems existing in the prior art. By using a detachable structure, the gas sensor is placed on the outside of the main body, which facilitates the replacement of the gas sensor and improves the replacement efficiency of the gas sensor.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Please refer to the following: Figures 1-7 As shown, a gas detector is provided, including a main body 1, a gas sensor 4, and a data processing module. The main body 1 is formed by connecting two half-shells. The data processing module is disposed inside the main body 1. A connecting cylinder 2 is provided on the outer wall of the main body 1. The connecting cylinder 2 can be integrally set with the main body 1 to improve structural strength. The connecting cylinder 2 and the connecting cover 3 are detachably connected. The connecting cylinder 2 and the connecting cover 3 form a gas chamber. The gas sensor 4 is disposed in the gas chamber. The gas sensor 4 is detachably connected to the data processing module. The gas chamber is connected to the external environment. In this device, the gas sensor 4 is detachably disposed in the gas chamber. When the gas sensor 4 needs to be replaced, only the connecting cover 3 needs to be removed, the gas sensor 4 can be removed and a new gas sensor 4 can be replaced. Compared with disassembling the main body 1 to replace the gas sensor 4, it can save replacement time and improve replacement efficiency.

[0033] In this embodiment, the detachable connection between the connecting cylinder 2 and the connecting cover 3 is a threaded connection, that is, the outer peripheral wall of the connecting cylinder 2 is provided with an external thread, and the inner peripheral wall of the connecting cover 3 is provided with an internal thread. The internal thread and the external thread cooperate to achieve a threaded connection. In other embodiments, detachable connection methods such as snap-fit ​​connection and bolt connection can also be selected.

[0034] In this embodiment, the specific detachable connection structure between the gas sensor 4 and the data processing module is as follows: a sensor board 10 is provided at one end of the gas chamber near the main body 1, the pins 11 of the gas sensor 4 are plugged into the sensor board 10, and the sensor board 10 and the data processing module are connected by a ribbon cable, that is, the gas sensor 4 is electrically connected to the data processing module through the sensor board 10; in other embodiments, other structures that can realize the detachable connection between the gas sensor 4 and the data processing module can be selected.

[0035] The inner top wall of the connecting cover 3 contacts the end of the gas sensor 4 away from the main body 1. That is, after the connecting cover 3 is connected to the connecting cylinder 2, the inner top wall of the connecting cover 3 limits the gas sensor 4 from the end of the gas sensor 4 away from the main body 1 to prevent the gas sensor 4 from shaking in the gas chamber. At the same time, when the connecting cover 3 is screwed on, the gas sensor 4 can also be squeezed into place and inserted into the sensor plate 10.

[0036] A flexible pad can be placed at the contact point between the connecting cover 3 and the gas sensor 4 to prevent hard compression from damaging the gas sensor 4.

[0037] An air nozzle 5 is provided at the end of the connecting cover 3 away from the main body 1. An air pump is installed inside the main body 1, and an air outlet 6 is provided on the main body 1. The air inlet of the air pump is connected to the air chamber through a corresponding pipeline, and the air outlet is connected to the air outlet 6 through a corresponding pipeline. The air pump introduces the ambient air into the air chamber through the air nozzle 5 and fills the air chamber, so that the gas sensor 4 can come into contact with the ambient air more quickly and fully, which can effectively shorten the detection time.

[0038] Multiple air inlets 13 can also be arranged around the air nozzle 5 to improve the uniformity of air intake.

[0039] The connecting cover 3 and the connecting cylinder 2 are connected by a sealing thread. The sealing thread connection is achieved by fitting a sealing ring on the end of the connecting cylinder 2 near the main body 1. When the connecting cover 3 is screwed on, it cooperates with the main body 1 to squeeze the sealing ring and achieve a seal.

[0040] To facilitate the screwing of the connecting cover 3, in this embodiment, anti-slip textures are provided on the outer peripheral wall of the connecting cover 3 to facilitate the application of force; or an annular protrusion 9 is provided on the outer peripheral wall of the connecting cover 3, and anti-slip textures are provided on the outer peripheral wall of the annular protrusion 9.

[0041] In this embodiment, the connecting cylinder 2 is located on the top of the main body 1, and the air outlet 6 is located on the side of the main body 1, so as to avoid occupying the front and back space.

[0042] The main body 1 is equipped with a power supply, and a display 7 is installed on the main body 1. The display 7 is electrically connected to the data processing module and is used to display the detection data in real time. Both the display 7 and the data processing module are electrically connected to the power supply.

[0043] The main body 1 is equipped with control buttons 8 to control the opening and closing of the device.

[0044] The main body 1 has a charging port 12 at the bottom for easy charging of the power supply.

[0045] In actual use, when the gas detector is turned on, the air pump starts to draw ambient air into the gas chamber from the air nozzle 5. The gas sensor 4 in the gas chamber begins to detect the gas and transmits the detection information to the data processing module, and finally displays the detection data on the display 7. When the gas sensor 4 needs to be replaced, simply remove the connecting cover 3, pull out the gas sensor 4, and replace it with a new gas sensor 4.

[0046] Any adaptive changes made according to actual needs are within the scope of protection of this invention.

[0047] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
