[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The purpose of the present invention is to provide a gas detector to solve the problems existing in the prior art. Through a detachable structure, a gas sensor is placed outside the main body to facilitate replacement of the gas sensor and improve the replacement efficiency of the gas sensor.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to Figure 1 to Figure 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 arranged in the main body 1, and a connecting cylinder 2 is arranged on the outer wall of the main body 1. The connecting cylinder 2 can be arranged integrally with the main body 1 to improve the structural strength. The connecting cylinder 2 and the connecting cover 3 are detachably connected, and the connecting cylinder 2 and the connecting cover 3 are arranged to form an air chamber, in which a gas sensor 4 is arranged, and the gas sensor 4 is detachably connected to the data processing module, and the air chamber is connected to the external environment. In this device, the gas sensor 4 is detachably arranged in the air chamber. When the gas sensor 4 needs to be replaced, it is only necessary to remove the connecting cover 3, dismantle the gas sensor 4 and replace it with a new gas sensor 4. Compared with disassembling the main body 1 to replace the gas sensor 4, the replacement time can be saved and the replacement efficiency can be improved.

[0024] In this embodiment, the detachable connection method between the connecting tube 2 and the connecting cover 3 is a threaded connection, that is, an external thread is set on the outer peripheral wall of the connecting tube 2, and an internal thread is set on the inner peripheral wall of the connecting cover 3, and the internal thread and the external thread cooperate to realize the threaded connection; in other embodiments, detachable connection methods such as snap connection and bolt connection can also be selected.

[0025] In the present 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 close to the main body 1, and the pin 11 of the gas sensor 4 is plugged into the sensor board 10. The sensor board 10 and the data processing module are connected via a flat cable, that is, the gas sensor 4 is electrically connected to the data processing module via 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.

[0026] 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 tube 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 air chamber. At the same time, when the connecting cover 3 is screwed, the gas sensor 4 and the sensor board 10 can also be squeezed into place.

[0027] A flexible pad may be provided at the contact position between the connection cover 3 and the gas sensor 4 to prevent the gas sensor 4 from being damaged by hard squeezing.

[0028] An air nozzle 5 is provided at the end of the connecting cover 3 away from the main body 1, an air pump is provided in the main body 1, and an air outlet 6 is provided on the main body 1. The air inlet end of the air pump is connected with the air chamber through a corresponding pipeline, and the air outlet end is connected with the air outlet 6 through a corresponding pipeline. The external environmental air is introduced into the air chamber through the air nozzle 5 by the air pump, and the air chamber is filled, so that the gas sensor 4 can contact with the external environmental air more quickly and fully, which can effectively shorten the detection time.

[0029] A plurality of air inlets 13 may also be arranged around the air nozzle 5 to improve the uniformity of air intake.

[0030] The connection cover 3 and the connection tube 2 are sealed with threads, and the sealing thread connection is as follows: a sealing ring is sleeved on one end of the connection tube 2 close to the main body 1, and when the connection cover 3 is screwed, the sealing ring is squeezed with the main body 1 to achieve sealing.

[0031] In order to facilitate the screwing of the connection cover 3, in this embodiment, anti-slip grooves are provided on the outer peripheral wall of the connection cover 3 to facilitate the application of force; or a circle of annular protrusions 9 are provided on the outer peripheral wall of the connection cover 3, and anti-slip grooves are provided on the outer peripheral wall of the annular protrusion 9.

[0032] In this embodiment, the connecting tube 2 is arranged on the top of the main body 1, and the air outlet 6 is arranged on the side of the main body 1 to avoid occupying the front and back space.

[0033] A power source is arranged in the main body 1 , and a display 7 is arranged on the main body 1 . The display 7 is electrically connected to the data processing module for displaying the detection data in real time. Both the display 7 and the data processing module are electrically connected to the power source.

[0034] The main body 1 is provided with a control button 8 for controlling the opening and closing of the device.

[0035] A charging port 12 is provided at the bottom of the main body 1 for convenient charging of the power supply.

[0036] During actual use, the gas detector is turned on, and the air pump is started to suck the external environment gas into the air chamber through the air nozzle 5. The gas sensor 4 in the air chamber starts to detect, and transmits the detection information to the data processing module, and finally presents the detection data on the display 7; when the gas sensor 4 needs to be replaced, just remove the connecting cover 3, pull out the gas sensor 4 and replace it with a new gas sensor 4.

[0037] Adaptive changes made according to actual needs are all within the protection scope of the present invention.

[0038] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
