[0024] 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.

[0025] Example 1: like Figures 1 to 7 As shown, Embodiment 1 of the present invention provides a multi-parameter advanced environmental detector, including components such as a housing 1, an air inlet 4, an air collection pipe 7, and an air pump 8. The housing 1 is generally cylindrical, and multiple air inlets 2 are provided at the bottom of the housing 1 to form an air intake grille, which protects the internal components while not affecting the entry of outside air. A main board 9 is installed inside the housing 1, and multiple electrochemical sensors 3 are soldered onto the main board 9, which are used to detect different gas content parameters in the air.

[0026] like Figure 3To ensure that each sensor 3 does not interfere with each other, a plurality of detection pipelines 6 are connected to the top of the air inlet cylinder 4, each detection pipeline 6 is independently provided, and one sensor 3 is installed in each detection pipeline 6. When the external air enters the detection pipeline 6, the electrochemical sensor 3 can react with the corresponding component in the air to detect the content of the component. The electrochemical sensor 3 is a conventional sensor 3 for existing air detection, and further description is not repeated. The plurality of detection pipelines 6 are communicated with the gas collecting pipe 7 at the end away from the air inlet cylinder 4, and the gas collecting pipe 7 serves as a gas flow collection channel. The plurality of detection pipelines 6 are uniformly distributed between the gas collecting pipe 7 and the air inlet cylinder 4, and the length and shape of each detection pipeline 6 are the same, which makes the air pressure in each detection pipeline 6 consistent.

[0027] The air pump 8 is fixedly installed in the housing 1, and the air inlet end of the air pump 8 is communicated with the gas collecting pipe 7 through the buffer chamber 30. When the air pump 8 is started to work, a negative pressure is formed in the buffer chamber 30, so that the external air enters from the air inlet hole 2 at the bottom of the housing 1, and the air flows through the air inlet cylinder 4, each detection pipeline 6, the gas collecting pipe 7 and the buffer chamber 30 in turn, and finally is discharged from the air outlet end of the air pump 8. The buffer chamber 30 uses the compressibility of air to absorb energy and smooth the air pressure fluctuation of the air pump 8, so that the air pressure in each detection pipeline is in a relatively stable state, and the detection accuracy is improved.

[0028] The air inlet cylinder 4 is provided with an air inlet treatment assembly for pretreating the entering air. The air inlet treatment assembly includes a dust filter screen 5 installed at the air inlet end of the air inlet cylinder 4 and a dehumidification chamber 10 arranged in the air inlet cylinder 4. The dust filter screen 5 is made of multiple layers of metal mesh or high molecular material, which can effectively intercept large particles of dust and impurities in the air. The dehumidification chamber 10 is located above the dust filter screen 5, and silica gel particles are filled in the dehumidification chamber 10 as a desiccant, and the silica gel particles have high moisture absorption. The air is driven by the air pump 8 to pass through the dust filter screen 5 first to remove solid particulate matter, and then enters the dehumidification chamber 10, and the silica gel particles absorb the moisture in the air to reduce the humidity of the air. The dry and clean air after filtering and dehumidification is then introduced into each detection pipeline 6 for gas component detection by the corresponding sensor 3. Since each sensor 3 works independently and the detected air is not contaminated by other sensors 3, the detection result has high accuracy. At the same time, the pretreatment process effectively avoids the damage of dust and moisture to the sensor 3, and significantly prolongs the service life of the sensor 3.

[0029] Example Two On the basis of example one, the multi-parameter advanced environmental detector provided by the present embodiment further optimizes the structure of the air inlet cylinder 4 and the maintenance assembly to realize the self-cleaning maintenance function. As shown in Figure 3As shown, the air inlet 4 includes a connecting pipe 11 and an air inlet pipe 13. The top of the connecting pipe 11 is sealed to multiple detection pipes 6. The dehumidification chamber 10 is rotatably mounted on the bottom of the connecting pipe 11. Multiple vent holes 12 are provided at both the top and bottom of the dehumidification chamber 10 to ensure air circulation. The air inlet pipe 13 is fitted onto the air inlet end of the dehumidification chamber 10 and rotates synchronously with the dehumidification chamber 10. The dust filter 5 is fixedly installed at the air inlet end of the air inlet pipe 13. The rotatable dehumidification chamber 10 facilitates the maintenance of the components.

[0030] like Figure 5 As shown, the maintenance components include an isolation chamber 14, multiple partitions, a guide pipe 18, and a heating unit 16. The isolation chamber 14 is located inside the connecting pipe 11 and is in close contact with the dehumidification chamber 10. An air supply pipe 15 is connected to one side of the isolation chamber 14. The heating unit 16, which can be an electric heating wire or a ceramic heater, is installed inside the isolation chamber 14. The dehumidification chamber 10 is divided into multiple independent compartments 17 by multiple radially distributed partitions, each compartment 17 being filled with silica gel particles. The isolation chamber 14 is connected to one of the compartments 17 through a vent 12. The guide pipe 18 is located inside the air inlet pipe 13 and is fixedly connected to a rod 22. A slot 21 is provided inside the connecting pipe 11, allowing the rod 22 to pass through the dehumidification chamber 10 and be inserted into the slot 21, thus achieving a fixed connection between the guide pipe 18 and the connecting pipe 11, and connecting it to the corresponding compartment 17 of the isolation chamber 14. The lower end of the guide pipe 18 extends to the vicinity of the inner surface of the dust filter 5. In this way, the guide pipe 18 can maintain its working relationship with the isolation chamber 14. When the dehumidification chamber 10 rotates, the guide pipe 18 can still work with the isolation chamber 14 to face the upper and lower ends of the other chamber 17.

[0031] The air outlet end of the air pump 8 is connected with an air outlet pipe 19, and the air supply pipe 15 is communicated with the air outlet pipe 19 through a reversing valve 20. In the normal detection mode, the reversing valve 20 is closed to the air supply pipe 15, and the air discharged by the air pump 8 is directly discharged out of the shell 1 through the air outlet pipe 19. In the maintenance mode, the reversing valve 20 switches the passage to communicate the air outlet pipe 19 with the air supply pipe 15, at this time, the air discharged by the air pump 8 enters the air supply pipe 15 and flows to the isolation chamber 14. The air flow is heated by the heating unit 16 in the isolation chamber 14 to become hot air, and the hot air passes through the corresponding bin chamber 17 of the isolation chamber 14 to dry the silica gel particles in the bin chamber 17, remove the moisture absorbed by the silica gel particles, and restore the dehumidification capacity of the silica gel particles. At the same time, the hot air flows downward along the guide pipe 18 and is blown out from the long strip-shaped air outlet at the bottom of the guide pipe 18 to impact the inner side of the dust filter screen 5 in the opposite direction to blow off the dust. The long and narrow air outlet can improve the air flow rate and improve the dust removal effect. The bottom of the plug rod 22 penetrates the dust filter screen 5 and is fixed with a brush rod 23, and dense bristles are arranged on the brush rod 23. The position of the bristles corresponds to the air outlet. When the dehumidification chamber 10 rotates, the dust filter screen 5 rotates with the dehumidification chamber 10 to relatively move the bristles with the outer surface of the dust filter screen 5, thereby physically brushing the surface of the dust filter screen 5. When the hot air is blown out, the air flow further blows away the residual dust and floating dust on the brushed dust filter screen 5 to realize automatic cleaning.

[0032] The present application fixes a baffle 24 in the connecting pipe 11, and a flow limiting hole 25 is formed in the center of the baffle 24. After the air flow entering from the dust filter screen 5 passes through the dehumidification chamber 10, it is hindered by the baffle 24 and can only pass through the flow limiting hole 25. The air flow rate at the flow limiting hole 25 is accelerated, and the air can be further mixed when passing through the flow limiting hole 25, so that the distribution of the components in the air is more uniform. At the same time, a flow equalizing plate 26 is fixed on the baffle 24, and the flow equalizing plate 26 faces the flow limiting hole 25. After the high-speed air flow impacts the flow equalizing plate 26, it is dispersed again and uniformly flows to each detection pipe 6, thereby improving the uniformity of the air flow distribution and the consistency of the air flow components in each detection pipe 6.

[0033] Example Three On the basis of example one and example two, a motor 27 is fixedly installed on the side wall of the connecting pipe 11, and a gear 28 is fixed on the output shaft of the motor 27. At the same time, a tooth ring 29 is fixed on the outer wall of the dehumidification chamber 10, and the tooth ring 29 is engaged with the gear 28 to form a transmission mechanism. When the motor 27 is started, the dehumidification chamber 10 is driven to slowly rotate relative to the connecting pipe 11 through the gear 28 and the tooth ring 29, thereby changing the cooperation relationship between the bin chamber 17 and the isolation chamber 14.

[0034] In the maintenance mode, the reversing valve 20 switches the air circuit, so that the air discharged by the air pump 8 is heated by the heating unit 16, and then the silica gel particles in the current warehouse 17 communicated with the isolation chamber 14 are dried. At the same time, the motor 27 is intermittently started according to the preset maintenance period, driving the dehumidification chamber 10 to rotate. The rotation of the dehumidification chamber 10 drives the air inlet pipe 13 and the dust screen 5 to rotate synchronously, while the guide pipe 18 and the brush rod 23 are fixed through the insertion rod 22 and the connecting pipe 11, keeping static state. Therefore, the bristles on the brush rod 23 produce relative motion with the rotating dust screen 5, fully brushing the entire surface of the dust screen 5, ensuring that there is no dead angle for cleaning dust.

[0035] With the rotation of the dehumidification chamber 10, the isolation chamber 14 is sequentially communicated with different warehouses 17 through the air hole 12, and the hot air circulates to dry the silica gel particles in each warehouse 17, so that all the silica gel particles gradually restore the moisture absorption performance, realize the maintenance cycle, significantly reduce the artificial maintenance demand, and improve the long-term stability and detection accuracy of the equipment.

[0036] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
