Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0021] like Figure 1 As shown, a multi-channel high-precision sample automatic transmission system includes a sample transmission unit 1, a multi-way valve 2 is built in the sample transmission unit 1, a storage unit 5 and a pure water unit 8 are connected to the input end of the multi-way valve 2, a channel 6 is connected to the output end of the multi-way valve 2, and an analytical instrument 7 is connected to the end of the channel 6. A power mechanism 3 for providing transmission power for the channel 6 is provided in the sample transmission unit 1, and a control unit 4 for controlling the transmission sequence and interval of the multi-way valve 2 is also built in the sample transmission unit 1. More specifically, the sample transmission unit 1 can be controlled to communicate with the channel 6 through the multi-way valve 2, and the power mechanism 3 is used as a power source to send the sample into the channel 6 and to the corresponding analytical instrument 7. By using multiple parallel channels 6 as sample transmission channels, parallel transmission of samples is realized, thereby significantly improving the transmission efficiency, wherein the control unit 4 can automatically judge and control the sample to be sent to a specific channel 6 according to the characteristics and analysis requirements of the sample, and the control unit 4 supports serial management of the sample channel, and transmits the sample in sequence according to the preset sequence order.

[0022] The inner core of channel 6 is a polytetrafluoroethylene pipe, and the outside of the pipe is provided with a polyvinyl chloride protective layer. It should be noted that polytetrafluoroethylene has excellent chemical stability and inertness, and can withstand the erosion of a variety of highly corrosive chemicals, ensuring that the sample is not contaminated or affected during the transmission process. Secondly, the inner wall of polytetrafluoroethylene is smooth and has a low friction coefficient, which can reduce the resistance of the sample in the pipeline and is conducive to the smooth transmission of the sample. Thirdly, the surface has very strong non-adhesiveness and is not easy to adhere to substances, which is conducive to the accurate transmission of the sample and avoidance of cross contamination.

[0023] There are multiple channels 6, and a control valve is provided on the surface of each channel 6. More specifically, by using multiple channels 6 as sample transmission channels, each channel can be independently controlled to achieve parallel transmission of samples, thereby significantly improving transmission efficiency.

[0024] The control unit 4 is pre-entered with the numbers of the storage unit 5, the channel 6 and the pure water unit 8, and the control unit 4 is electrically connected to the multi-way valve 2 and the channel 6. It should be noted that by manually entering the sample number into the program of the control unit 4, when a specific sample needs to be analyzed, the switching of the channel 6 can be controlled by the control program to realize that the same sample is sent from the channel 6 to the corresponding analysis instrument 7, or different samples can be sent from the channel 6 to the corresponding analysis instrument 7 at a set time interval, so as to realize serialized management.

[0025] The power mechanism 3 is a syringe pump, and the transmission rate of the power mechanism 3 is eighty meters per three minutes. More specifically, the system uses a high-precision syringe pump as the power source for sample transmission, ensuring fast and accurate sample transmission within three minutes within a distance of eighty meters. The high-precision characteristics of the syringe pump ensure the accuracy and reliability of sample transmission.

[0026] The number of power mechanisms 3 corresponds to the number of channels 6. It should be noted that by equipping each channel 6 with a power mechanism 3, rapid and accurate transmission of the sample can be achieved.

[0027] In summary: the multi-way valve 2 can be used to control the sample transmission unit 1 to be connected with the channel 6. The power mechanism 3 is used as a power source to send the sample into the channel 6 and transport it to the corresponding analysis instrument 7. Multiple parallel channels 6 are used as sample transmission channels to achieve parallel transmission of samples, thereby significantly improving the transmission efficiency. The control unit 4 can automatically judge and control the sample to be sent to a specific channel 6 according to the characteristics of the sample and the analysis requirements, and the control unit 4 supports serial management of the sample channel, and transmits the samples in sequence according to a preset sequence order. During use, technical means such as multi-channel parallel transmission, automatic judgment and switching, high-precision injection and serial management are used to achieve fast, accurate and efficient transmission of samples, significantly improving the accuracy and efficiency of laboratory sample analysis.
