[0022] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0023] The terms "including" and "having" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0024] One of the preferred embodiments of the present application is as follows: Figures 1 to 5As shown, a liquid chromatograph for detecting aromatherapy comprises a liquid chromatograph body 1 and a plurality of placement slots 11 provided on the liquid chromatograph body 1; a clamping assembly 2 is arranged inside the placement slots 11, and the clamping assembly 2 is convenient for clamping and fixing the bottle body placed in the placement slots 11, and the clamping assembly 2 and the liquid chromatograph body 1 cooperate with each other through a locking structure 3; when clamping and fixing, the bottle body can be placed in the placement slots 11, and when the bottle body is placed in the placement slots 11, the bottle body squeezes the clamping assembly 2 due to its own weight or pressure on the bottle body, and then the clamping assembly 2 is pressed against the side of the bottle body in the placement slots 11, and then the bottle body is clamped firmly, and when the clamping assembly 2 is firmly clamped, the firmly clamped clamping assembly 2 is locked and fixed by the locking structure 3, so as to facilitate better firm clamping, improve the stability of the device, and has simple operation, reasonable setting and strong practicality.

[0025] In this embodiment, Figure 3 As shown, it can be understood that avoidance grooves 12 are opened on both sides of the placement groove 11, and limiting rods 13 are arranged in the two avoidance grooves 12, so that the clamping assembly 2 can be moved to the side of the bottle body by the limiting rods 13 for stable clamping.

[0026] In this embodiment, Figures 2 to 5 As shown, the clamping assembly 2 includes an inclined plate 21 installed in the placement groove 11 by a spring, and an inclined clamp block 22 slidably installed on the side of the corresponding limiting rod 13; the two inclined plates 21 and the inclined clamp blocks 22 are connected and matched by a traction structure 23; when clamping, the bottle body is placed in the placement groove 11 onto the inclined plate 21, and then moves downward by its own weight or is pressed downward to make the inclined plate 21 move downward. The inclined plate 21 moves downward through the traction structure 23 so that the two inclined clamp blocks 22 slide along the corresponding limiting rod 13 to the two sides of the bottle body for clamping, thereby clamping the bottle body. When firmly clamping, the two firmly clamped inclined clamp blocks 22 are fixed by the locking structure 3, thereby improving the firm clamping effect of the clamping assembly 2.

[0027] In this embodiment, Figure 4 and Figure 5 As shown, it can be understood that the traction structure 23 includes a traction block 231 arranged on the inclined side of the inclined plate 21, and a traction groove 232 opened on the inclined side of the inclined clamping block 22; the traction block 231 cooperates with the traction groove 232; when clamping, the inclined plate 21 moves downward to drive the traction block 231 to move downward, and the traction block 231 moves and slides in the traction groove 232, thereby driving the inclined clamping block 22 to move toward the side of the bottle body to clamp and fix it.

[0028] In this embodiment, Figures 3 to 5As shown, the locking structure 3 includes a locking block 31 elastically installed on the side of the inclined clamping block 22 by a spring, and a locking groove 32 provided on the side of the liquid chromatograph body 1; the locking block 31 and the locking groove 32 cooperate with each other; when locking is performed, the inclined clamping block 22 slides with the elastically compressed locking block 31, and when the inclined clamping block 22 is clamped with the side of the bottle body, the compressed locking block 31 just slides to the bottom of the locking groove 32, so that the locking block 31 is elastically reset to extend into the locking groove 32, so as to lock and fix the inclined clamping block 22, so as to better lock and fix the clamping assembly 2 and firmly clamp the lifting device.

[0029] It should be known that if Figure 4 and Figure 5 As shown, in order to better unlock and take the bottle body, a guide rod can be placed on the side of the liquid chromatograph body 1, and the guide rod is extended into the locking groove 32, and then the locking block 31 is elastically squeezed to completely extend out of the locking groove 32. Due to the needs of the experiment, the liquid in the bottle body is completely used up. At this time, the weight of the bottle body becomes lighter. At this time, the inclined plate 21 is elastically reset by the spring to drive the inclined plate 21 to move upward. The upward movement of the inclined plate 21 drives the inclined clamping block 22 away from the side of the bottle body through the traction block 231, and then drives the compressed locking block 31 away from the locking groove 32. At this time, the bottle body can be directly taken out without the clamping of the inclined clamping block 22, and then a new bottle body can be replaced for operation.

[0030] In this embodiment, Figure 1 and Figure 2 As shown, it can be understood that in order to better facilitate the simultaneous liquid extraction test with multiple bottles and avoid confusion of pipelines, a frame 14 is provided on the side of the liquid chromatograph body 1, and a connecting plate 141 is provided on the side of the frame 14. A plurality of grooves 142 are provided on the side of the connecting plate 141. The grooves 142 can be used to lay out the corresponding pipelines, thereby improving the overall aesthetics of the device and preventing the pipelines from being too messy and affecting the device.

[0031] In this embodiment, Figure 1 and Figure 2 As shown, it should be known that in order to better bind the pipelines, multiple rubber hooks are provided on the sides of the multiple slots 142, so as to facilitate the hooking and binding of the pipelines through the rubber hooks and improve the reasonable layout of the pipelines.

[0032] In this embodiment, Figure 1 and Figure 2 As shown, in order to uniformly arrange the laid pipelines, a cable arrangement block is installed on the side of the frame 14, and the cable arrangement block can be used to centrally tie and arrange multiple pipelines laid out from the slots and extend into the liquid chromatograph body 1, thereby improving the overall cable bundling effect of the device, preventing the pipelines from being too messy, and operators from accidentally pulling the pipelines due to carelessness, thereby causing the liquid chromatograph body 1 to move or overturn.
