[0025] The utility model provides a detection source sampling device.

[0026] Reference Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the detection source sampling device of the utility model from an angle; Figure 2 This is a schematic structural diagram of the detection source sampling device of the utility model from another angle; Figure 3 This is a schematic structural diagram of the detection source sampling device of the utility model from another angle.

[0027] like Figures 1 to 3 As shown, in an embodiment of the utility model, the detection source sampling device includes a sampling body 1 and a protective member 2, and a connector 3 connected to the interior is provided on the outside of the sampling body 1, and the connector 3 is used to connect the detection mechanism; the protective member 2 is connected to the outside of the sampling body 1 and is located on the peripheral side of the connector.

[0028] The technical solution of the utility model provides a protective member 2 on the peripheral ring of the joint 3, and the joint 3 is located at the center of the protective member 2, so as to provide all-round protection for the joint 3. When the sampling body 1 is collided or dropped during production, use or transportation, the protective member 2 is collided first, thereby protecting the joint 3, avoiding the joint 3 from breaking due to the collision, and ensuring the normal use of the joint 3. The protective member 2 is made of hard plastic material and has good impact resistance to block external impact.

[0029] Among them, the sampling body 1 is used to provide power for sampling, and the sampling body 1 also has a calculation module inside, which is used to calculate the gas flow rate to control the gas flow rate; the connector 3 is connected to the detection mechanism through an external hose, and the sampling process is: the gas in the atmosphere passes through the sampling body 1, and then is transported to the detection mechanism by the connector 3 and the external hose for gas detection and analysis.

[0030] Furthermore, the sampling body 1 is provided with a display screen and an adjusting knob. The display screen can intuitively obtain flow data, and the adjusting knob can adjust the power of the sampling body 1, etc.

[0031] In an optional embodiment, the protective member 2 is annular and is arranged around the circumference of the joint 3. The protective member 2 provides all-round protection to the joint 3 to prevent the joint 3 from being hit.

[0032] In an optional embodiment, the height of the highest point of the end of the protective member 2 is greater than or equal to the height of the connector 3. The overall height of the protective member 2 is higher than the height of the connector 3. When the sampling body 1 falls, the connector 3 faces the ground, and the protective member 2 first contacts the ground to protect the connector 3.

[0033] Among them, the protective part 2 can be integrally formed and set on the sampling body 1, which can save assembly steps and assembly time, but the protective part 2 cannot be replaced after being damaged; it can also be detachably connected to the sampling body 1 and can be used on different sampling bodies 1. During the use of the sampling body 1, the protective part 2 is damaged by external force, and the protective part 2 can be removed and replaced.

[0034] Furthermore, the detection source sampling device also includes a connecting portion 21, which is formed by the protective member 2 being bent and extended toward one end of the sampling body 1, and the connecting portion 21 is attached to the surface of the sampling body 1 and is threadedly connected to the sampling body 1. In this embodiment, the connecting portion 21 is provided with a hole 211, and the sampling body 1 is provided with a locking groove corresponding to the hole 211. After the hole 211 of the connecting portion 21 corresponds to the locking groove, the screw is passed through the hole 211 and screwed into the locking groove to complete the installation of the protective member 2; in addition, the protective member 2 can also be connected in a snap-fit ​​manner, the protective member 2 is provided with a snap-fit, and the sampling body 1 is provided with a slot, and the snap-fit ​​is correspondingly inserted into the slot to complete the installation of the protective member 2.

[0035] In an optional embodiment, the material of the protective member 2 is hard plastic, and common hard plastics are polyethylene, polypropylene, polyvinyl chloride, and composite plastics obtained by copolymerization of polycarbonate and acrylonitrile-butadiene-styrene.

[0036] In this embodiment, the protective member 2 is made of a composite plastic obtained by copolymerization of polycarbonate and acrylonitrile-butadiene-styrene (i.e., PC / ABS composite plastic). Since the composite plastic obtained by copolymerization of polycarbonate and acrylonitrile-butadiene-styrene is a thermoplastic plastic composed of an alloy of polycarbonate and polyacrylonitrile, it combines the excellent properties of the two materials, so that the manufactured protective member 2 has the characteristics of high strength and impact resistance, and can protect the joint 3 when the sampling body 1 is hit, and the PC / ABS composite plastic is not easily damaged. At the same time, the PC / ABS composite plastic is also a non-toxic, odorless, renewable and recyclable green environmentally friendly material. When the protective member 2 is damaged during the use of the sampling body 1, the replaced protective member 2 can be reprocessed into a similar product or a different product.

[0037] In an optional embodiment, the thickness of the protective member 2 ranges from 2 mm to 3 mm. If the thickness of the protective member 2 is too thin, it cannot protect the joint 3, and if the thickness of the protective member 2 is too thick, it will cause a waste of resources. Therefore, within this thickness range, the protective member 2 is not easily damaged by collision and protects the joint 3.

[0038] In an optional embodiment, the distance between the inner wall of the protective member 2 and the outer wall of the joint 3 is in the range of 3 mm to 4 mm. Within this distance range, there is sufficient space to install the external hose. By setting a suitable distance, the external hose can be pressed against the joint 3 through the inner wall of the protective member 2, so that the external hose is not easily removed from the joint 3 and affects gas delivery.

[0039] Furthermore, in this embodiment, the protective member 2 is a cylindrical structure, and the joint 3 is located at the center of the protective member 2, so that the protective member 2 can protect the joint 3 in all directions.

[0040] Furthermore, the connector 3 is integrally formed with the sampling body 1, which saves the assembly process and ensures the sealing of the connection between the connector 3 and the sampling body 1, thereby avoiding leakage during the gas sampling process and affecting the gas analysis results.

[0041] In order not to block the external hose from being connected to the connector 3, the free end surface of the protective member 2 is recessed toward one side of the sampling body 1 to form two clearance areas 22. The two clearance areas 22 are located on opposite sides of the protective member 2. The clearance areas 22 are used to cooperate with the state when the fingers grasp the external hose. When the external hose is connected to the connector 3, the fingers can better apply force to connect the external hose and the connector 3.

[0042] Furthermore, the edge of each clearance area 22 is in an arc shape, and the edge of the clearance area 22 adopts an arc transition and is blunted by grinding, so that the clearance area 22 is more compatible with the hand and avoids the edge of the clearance area 22 being too sharp to scratch the hand or the hose.

[0043] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
