Description

Technical Field

[0001] This application relates to the field of gas detection and analysis technology, and in particular to a novel gas detector. Background Technology

[0002] Gas detectors are indispensable tools in industrial production, environmental monitoring, and laboratory research. By extracting and analyzing sample gases, these instruments can quickly detect the composition and concentration of gases, thereby ensuring safety or enabling process control. Typically, these detectors include a pump for actively extracting sample gas, and one or more sensors for analyzing the specific components of the gas.

[0003] In existing gas detector designs, the air inlet is typically equipped with filter media, such as sponges, to prevent dust and particulate matter from entering the instrument and damaging sensitive sensors or pumps. However, this design has certain drawbacks: once the filter media becomes clogged with contaminants or residues accumulate, it affects the detector's accuracy and response time. While replacing the filter media is one solution, frequent maintenance is impractical in continuous monitoring or online detection applications.

[0004] Therefore, a major technical problem currently facing gas analyzers on the market is how to maintain the accuracy and performance of the analyzer without excessively increasing the maintenance burden. Summary of the Invention

[0005] This application aims to overcome the above-mentioned technical problems and provide a novel gas detector.

[0006] This application provides a novel gas detector, including a detector body, an air pump disposed within the detector body, an air inlet pipe disposed at one end of the detector body, and multiple layers of sponge disposed on the outside of the air inlet pipe. The air inlet pipe is characterized by having multiple chambers, each chamber containing a guide pipe communicating with the detector body. Each layer of sponge, chamber, and guide pipe is arranged in a one-to-one correspondence. A knob assembly is disposed on the air inlet pipe to control the air intake of individual chambers, guide pipes, and corresponding sponges, preventing residue on the sponge from affecting the accuracy of the detection.

[0007] Preferably, the knob assembly includes a turntable rotatably connected to the air intake pipe, and the turntable has an air intake hole for communicating with the air guide pipe.

[0008] Preferably, the side wall of the turntable is provided with a limiting component, which is used to limit the turntable and ensure that the air inlet and the air guide pipe are connected.

[0009] Preferably, the inner wall of the air intake pipe has multiple recessed holes, and the recessed holes are arranged one-to-one with the air guide pipe. When the plug is inserted into the recessed hole, the turntable can be fixed.

[0010] Preferably, the turntable is provided with anti-slip texture.

[0011] Preferably, the sponge is detachably connected to the air intake pipe.

[0012] In summary, the present invention has at least the following beneficial effects:

[0013] 1. Because the present invention adopts a multi-chamber design and an independent air intake control knob, it realizes independent control of the air intake of each chamber, thereby preventing the blockage of a single sponge filter layer from affecting the entire detection system and significantly improving the accuracy of gas detection.

[0014] 2. In this invention, a detachable sponge is preferably used. Since the blocked or contaminated sponge layer can be replaced separately without disassembling the entire air intake pipe, the maintenance process is greatly simplified and the maintenance cost is reduced.

[0020] The following is in conjunction with the appendix Figure 1-4 To further elaborate on this application:

[0021] Example 1 This example discloses a key improvement in the design and function of the air inlet pipe 11. The detector includes a detector body 1 with a built-in air pump for actively extracting ambient gas for analysis. An air inlet pipe 11 is located at one end of the detector body 1. This air inlet pipe 11 not only actively guides ambient gas into the detector, but its structure has also been cleverly improved to enhance the long-term stability and accuracy of the instrument. Specifically, the air inlet pipe 11 is internally divided into multiple independent chambers 12, which are completely isolated from each other to ensure that gas samples do not mix. Each chamber 12 is connected to the interior of the detector body 1 via a dedicated air guide pipe 13, ensuring that the gas sample can smoothly reach the sensor for analysis. This design avoids the problem in traditional single air inlet pipe 11 designs where clogging of the filter material or accumulation of residue affects overall performance. To prevent dust and particulate matter from entering the detector, each chamber 12 is equipped with an independent sponge 14 on its outer side. These sponges 14 are tightly attached to the outer wall of the air inlet pipe 11, effectively filtering out impurities in the ambient gas. To address the issue of clogging during long-term operation, the air intake pipe 11 is equipped with an innovative knob assembly. This knob assembly, through rotation, controls the independent air intake status of each chamber 12, air guide pipe 13, and corresponding sponge 14. Thus, even if the sponge 14 in a certain chamber 12 becomes clogged, the knob can be used to close that chamber 12, allowing other clean chambers 12 to continue testing, thereby significantly improving the instrument's continuous operation capability and testing accuracy. The air intake pipe 11 includes a mounting bracket 15, with a filter cartridge 16 covering the bracket 15. The sponge 14 is positioned between the mounting mesh and the filter cartridge 16. The sponge 14 and the chambers 12 within the air intake pipe 11 are arranged in corresponding layers. The filter cartridge 16 is secured with bolts and nuts.

[0022] The implementation principle of Example 1 is as follows: By using a multi-chamber design 12 and knob control, each chamber 12 and its corresponding sponge 14 can be maintained and replaced individually without affecting other normally functioning chambers 12. When the air pump is started, a specific chamber 12 is selected to open by turning the knob. After being filtered by the sponge 14, the gas enters the detector body 1 through the corresponding chamber 12 and the air guide tube 13 for sensor analysis. When the sponge 14 of a certain chamber 12 needs to be cleaned or replaced, the maintenance operation can be performed simply by turning the knob to close the chamber 12, while the rest of the instrument can still work normally. Example 2 The difference between this example and Example 1 lies in the specific construction of the knob assembly. In this example, the knob assembly includes a turntable 18 rotatably connected to the air inlet tube 11. The turntable 18 has one or more air inlets, the position and size of which are precisely designed so that when the turntable 18 is rotated to a specific position, it can be aligned with a specific chamber 12 and the air guide tube 13, thereby realizing the control of the air intake of that chamber 12. To ensure that the turntable 18 can stably remain in the required position after rotation and will not shift under the action of gas flow or external force, a limiting component is also provided on the side wall of the turntable 18. This limiting component can interact with a specific position on the inner wall of the air intake pipe 11, thereby achieving the positioning and locking of the turntable 18. When the turntable 18 rotates to a specific position, the limiting component will automatically lock, ensuring that the air intake hole is precisely aligned with the corresponding chamber 12 and air guide pipe 13, thus ensuring the stability and reliability of air intake. Example 3 Based on Example 1, this example further improves the structure of the air intake pipe 11 and the ease of operation of the turntable 18. First, multiple recessed holes 20 are opened on the inner wall of the air intake pipe 11, and these recessed holes 20 correspond one-to-one with each chamber 12 and air guide pipe 13. When the turntable 18 rotates to a specific position, the insertion post 19 on it is inserted into the recessed hole 20, thereby achieving the fixation of the turntable 18. This design is not only more stable and reliable, but also has a simple structure and low manufacturing cost. Secondly, to improve the ease of operation of the turntable 18, anti-slip textures 181 are provided on the outer surface of the turntable 18. These anti-slip textures 181 can effectively prevent the operator from slipping when rotating the turntable 18, improving the safety and accuracy of operation. Even in harsh environmental conditions, such as rain, oil stains, or when operating with gloves, the anti-slip textures 181 can provide sufficient friction to ensure that the turntable 18 can rotate smoothly and accurately to the required position. Example 4 Based on Example 1, the sponge 14 in this example is installed on the air inlet pipe 11 in a detachable connection manner. This design makes the replacement and maintenance of the sponge 14 more convenient and quick. When a sponge 14 needs to be cleaned or replaced, the operator can simply remove the sponge 14 to be replaced without disassembling the entire air inlet pipe 11. This not only greatly reduces the difficulty and cost of maintenance, but also improves the overall reliability and service life of the instrument.Meanwhile, this embodiment also provides various types of sponge 14 materials for users to choose from. Different types of sponge 14 materials have different filtration effects and durability, and users can choose the most suitable type of sponge 14 according to actual detection needs and working environment conditions. This flexibility and diversity enable the new gas detector to adapt to a wider range of different application scenarios and needs. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
