Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: A heated filling device for liquid culture medium includes a frame 1, a three-jaw gripping module 3 on the top of the frame 1, a cylinder 5 fixedly mounted at the rear top of the frame 1, and a cylinder 5 fixedly mounted on the top of a mounting frame 4, with a filling head 6 fixedly mounted through the output end of the cylinder 5 through the mounting frame 4. A heated filling mechanism 2 is provided above the frame 1 to quickly intercept the liquid culture medium after filling and prevent dripping. The heated filling mechanism 2 includes: The heating and storage unit 21 is located above the frame 1 and is used for storing, heating and transporting liquid culture medium. The anti-drip interception unit 22 is located below the filling head 6 and includes a filling tube 221 fixedly installed below the filling head 6. A valve port plate 224 and a fixing plate 222 are fixedly installed inside the filling tube 221. A valve body 223 is slidably installed inside the fixing plate 222, and an inverted conical block above the valve body 223 seals the valve port plate 224, thereby achieving rapid interception and low-level interception of liquid culture medium.

[0018] The inverted conical plug above the valve body 223 and the valve port plate 224, combined with the elastic drive of the spring 227, can achieve a fast and tight seal at the end of filling, significantly reducing residual droplets after filling and effectively avoiding waste of precious culture medium and material loss.

[0019] In this embodiment, the anti-drip interception unit 22 also includes a baffle 226 fixedly installed on the surface of the valve body 223. A spring 227 is installed on the surface of the valve body 223, and the spring 227 is located between the fixed plate 222 and the baffle 226. The baffle 226 is reset and the valve body 223 is closed with the valve port plate 224 by the elastic force of the spring 227 itself.

[0020] When the spring 227 is compressed, it stores energy and provides an instantaneous elastic force to push the baffle 226 when the filling head is raised at the end of filling, causing the valve body 223 to move upward. The spring force acts directly on the valve body 223, ensuring that its inverted conical plug can quickly and tightly press against the valve port plate 224.

[0021] In this embodiment, a plurality of liquid outlets 228 are provided on the outer side of the filling tube 221, and there is a height difference between the liquid outlets 228 and the fixing plate 222. A rubber sleeve 225 is fixedly installed on the surface of the upper block of the valve body 223.

[0022] The rubber sleeve 225 covers the surface of the valve body 223 plug, providing a flexible sealing interface. The position where there is a drop between the outlet 228 and the fixing plate 222, combined with the position design of the valve plate inside the filling tube, achieves low-level interception and ensures that there is almost no liquid dripping at the end of the filling tube 221, minimizing the waste of precious culture medium and the risk of cross-contamination.

[0023] In this embodiment, the heating liquid storage unit 21 includes a liquid storage tank 211 fixedly installed on the top of the frame 1. A housing 212 is fixedly installed on the surface of the liquid storage tank 211, and a heating tube 213 is fixedly installed between the liquid storage tank 211 and the housing 212. A heater 214 is fixedly installed on the rear side of the housing 212, and one end of the heating tube 213 passes through the housing 212 and is fixedly connected to the heater 214. A temperature sensor 215 is fixedly installed at the bottom of the inner cavity of the liquid storage tank 211 for detecting the temperature inside the liquid storage tank 211.

[0024] The temperature sensor 215 is model DS18B20. The temperature sensor 215 monitors the temperature of the liquid in the tank in real time and feeds the data back to the heater 214 to dynamically adjust the heating power.

[0025] In this embodiment, the outer shell 212 is fixedly installed on the surface of the liquid storage tank 211 in a spiral shape, so as to achieve uniform heating of the inside of the liquid storage tank 211.

[0026] In this embodiment, a pump 216 is fixedly installed on the top of the frame 1. The input end of the pump 216 is connected to the inside of the liquid storage tank 211 through an input pipe. A connecting pipe 217 is fixedly installed on the output end of the pump 216, and one end of the connecting pipe 217 is fixedly connected to the filling head 6.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] During operation, firstly, liquid culture medium is injected into the interior of the storage tank 211 through the inlet at the top of the storage tank 211. Then, the heater 214 operates to heat the heating tube 213, which in turn heats the interior of the storage tank 211. Then, the container to be filled is placed in the middle above the three-jaw clamping module 3. The three-jaw clamping module 3 clamps the container. The cylinder 5 moves and drives the filling head 6 to move down, so that the storage tank 211 enters the container. The valve body 223 contacts the bottom of the inner cavity of the container. The valve body 223 squeezes the spring 227 through the baffle 226. The block above the valve body 223 separates from the valve port plate 224. The pump 216 runs and injects the liquid culture medium inside the storage tank 211 into the storage tank 211 through the connecting pipe 217 and the filling head 6. It enters the fixed plate 222 through the valve port plate 224 and flows out through the outlet 228 to fill the container with liquid culture medium. Finally, the cylinder 5 moves the filling head 6 and filling tube 221 upwards, and the spring 227 pushes the baffle 226 through its own elastic force, causing the valve body 223 to move downwards. The plug above the valve body 223 seals the through hole of the valve plate 224, thus achieving flow interception.
