Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0062] In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0063] like Figures 1 to 15 As shown, an embodiment of the utility model provides a multi-channel switching structure, the structure comprising:

[0064] At least two flow channels, each of which is provided with a unidirectional conductive element 3 and a connecting piece 4;

[0065] A power member 5 connected to each of the connecting members 4, wherein the power member 5 is connected to each of the flow channels through the connecting members 4;

[0066] The power member 5 includes a first driving state and a second driving state; in the first driving state, the power member 5 connects the first part 11 of the first flow channel 1 and the second part 22 of the second flow channel 2 of the at least two flow channels to form a first transmission channel; in the second driving state, the power member 5 connects the first part 21 of the second flow channel 2 and the second part 12 of the first flow channel 1 to form a second transmission channel;

[0067] The control circuit is connected to the power member 5 and is used to control the power member 5 to switch between the first driving state and the second driving state.

[0068] In the embodiment of the utility model, in the case of multiple flow channels, the power member 5 is connected to the multiple flow channels through the connecting member 4, and by switching the driving state of the power member 5, the switching of multiple transmission channels can be realized in the multiple flow channels; taking two flow channels as an example, Figure 1 As shown, the flow channel connected to the consumable bin A on the left is the first flow channel 1, and the flow channel connected to the consumable bin B on the right is the second flow channel 2, and the first flow channel 1 and the second flow channel 2 are combined into an output pipeline 10; wherein, when the power member 5 is in the first driving state, the power member 5 connects the first part 11 of the first flow channel 1 and the second part 22 of the second flow channel 2 to form a first transmission channel, at which time, the consumables in the consumable bin A are transmitted through the first transmission channel; Figure 2 As shown, the first flow channel 1 and the second flow channel 2 are connected to Figure 1Similarly, the first flow channel 1 and the second flow channel 2 are combined into an output pipeline 10; wherein, when the power member 5 is in the second driving state, the power member 5 connects the first part 21 of the second flow channel 2 and the second part 12 of the first flow channel 1 to form a second transmission channel, at which time, the consumables in the consumable bin B are transmitted through the second transmission channel. It should be noted that, in general, one flow channel is connected to one consumable bin, and multiple consumable bins can be set as a consumable bottle with multiple divided sub-bins carrying different consumables, or can be set as multiple independent consumable bottles, which is not specifically limited in the present utility model.

[0069] It should also be noted that Figure 1 and Figure 2 The scenario of two flow channels is described. This embodiment may also include a scenario of multiple flow channels such as three flow channels or four flow channels. In this case, a unidirectional conductive element 3, a power component 5 and a connecting component 4 may be additionally provided to implement this solution, which is not limited here.

[0070] The connecting member 4 is located between the two one-way conducting elements 3 of the first flow channel 1 ( Figure 1 and Figure 2 ) and also between the two one-way conducting elements 3 of the second flow channel 2 ( Figure 1 and Figure 2 The power member 5 is a component capable of transmitting consumables, and the power member 5 includes but is not limited to a peristaltic pump, an air pump, etc. The first driving state and the second driving state corresponding to the peristaltic pump are a forward state and a reverse state, respectively.

[0071] like Figure 4 As shown, the front end of the one-way conductive element 3 is a flat body with a cutout. When the consumables are transmitted, the consumables are output through the cutout. The one-way conductive element can be made of soft materials such as soft glue and silicone. Since the cutout is the size of a gap and is made of soft materials, it can play a role in forward conduction transmission and reverse interception when conveying consumables. Optionally, the one-way conductive element can also be a cylinder, and the consumables are transmitted by setting a cutout at one end of the cylinder. It should be noted that the one-way conductive element 3 can be a conductive element with a function of preventing reverse flow (such as a one-way valve) or a conductive element with a reverse interception function (such as a duckbill valve), and the utility model does not limit its specific structure.

[0072] In the embodiment of the utility model, a power component 5 is connected to at least two flow channels through a connecting component 4, and through a control circuit, the power component 5 can be switched between a first driving state and a second driving state, thereby realizing the switching of a first transmission channel and a second transmission channel in the flow channel. The number of power components 5 in the embodiment of the utility model is relatively small, so the structure is simpler and the volume is smaller, and no additional air intake components such as solenoid valves are provided, so the sealing is better. In addition, a unidirectional conducting element 3 is also provided in the flow channel of the embodiment of the utility model, which can reduce the pressure difference when the power component 5 is working, so that the components in the flow channel can work more stably.

[0073] Optionally, the connecting member 4 includes:

[0074] A connector body 40, wherein the interior of the connector body 40 is a hollow structure;

[0075] A first interface 41, a second interface 42 and a third interface 43 respectively arranged on the connector body 40;

[0076] The first interface 41 and the second interface 42 are respectively connected to one of the one-way conducting elements 3 , and the third interface 43 is connected to the power component 5 .

[0077] In the embodiment of the utility model, Figure 5 As shown, the connector 4 includes a connector body 40, a first interface 41, a second interface 42 and a third interface 43. In actual application, if it is necessary to transfer consumables through a multi-channel switching structure, the first interface 41 needs to be connected to the consumable bin, and the second interface 42 needs to be connected to the output pipeline 10 for outputting consumables; wherein the interior of the connector body 40 is a hollow structure for transferring consumables, the third interface 43 is connected to the power member 5, and the first interface 41 and the second interface 42 are respectively connected to a unidirectional conductive element 3, which can play a role in forward conductive transmission and reverse interception when conveying consumables, and can reduce the gas consumption in the flow channel when the power member 5 is working, thereby reducing the pressure difference, so that the internal components can work stably. In addition, for the unidirectional conductive element 3 of the second interface 42, as Figure 1 and Figure 2 As shown, in the case where the first flow channel 1 and the second flow channel 2 share an output pipeline 10, if there is a second interface 42 of a connector 4 that is not provided with a unidirectional conductive element 3, there is a risk of consumables flowing back from one transmission channel to the other transmission channel. If the consumables transmitted by the two transmission channels are different, there is also a risk of consumables mixing.

[0078] Optionally, the first interface 41 is disposed at one end of the connector body 40 , the second interface 42 is disposed at the other end of the connector body 40 , and the third interface 43 is disposed on a side of the connector body 40 .

However, it should be noted that the above method is only a specific embodiment. The first interface 41 and the second interface 42 in the utility model are not limited to being respectively arranged at the two ends of the connector body 40, and the third interface is not limited to being arranged on the side of the connector body 40.

[0084] In the embodiment of the utility model, Figure 6 As shown, the power member 5 includes a driver 51, a pump head 52 and a hose 53, and is connected to each connector 4 through the hose 53. Specifically, both ends of the hose 53 are respectively connected to the third interface 43 of the connector 4. In actual use, if the power member 5 is in the first driving state, that is, the pump head 52 rotates forward, the extrusion block in the pump head 52 squeezes the hose 53 clockwise, and because of the pressure change, the consumables are moved along the Figure 1 The consumables are firstly sucked from a unidirectional conductive element 3 along the first part 11 of the first flow channel 1 to the hose 53 of the power member 5, and then squeezed from the hose 53 to the second part 22 of the second flow channel 2, and finally transmitted to the outside of the second flow channel 2; if the power member 5 is in the second driving state, that is, the pump head 52 is reversed, the squeezing block in the pump head 52 squeezes the hose 53 counterclockwise, and because of the pressure change, the consumables are sucked from the ... to the hose 53 of the power member 5, and then squeezed from the hose 53 to the second part 22 of the second flow channel 2, and finally transmitted to the outside of the second flow channel 2. Figure 2 The consumables are transmitted through the second transmission channel in the embodiment of the present invention. First, the consumables are sucked from a unidirectional conductive element 3 along the first part 21 of the second flow channel 2 to the hose 53 of the power part 5, and then squeezed from the hose 53 to the second part 12 of the first flow channel 1, and finally transmitted to the outside of the first flow channel 1.

[0086] A first fixing member 6, wherein a first groove is provided at one end of the first fixing member 6;

For each connecting member 4, one end is fixed with a unidirectional conductive element 3 through the first fixing member 6, and the other end is fixed with a unidirectional conductive element 3 through the second fixing member 7. When the consumables are transmitted, the consumables are transmitted along the conducting direction of the unidirectional conductive element 3. Usually, the conducting directions of the multiple unidirectional conductive elements 3 are consistent; specifically, as Figure 8 As shown, one end of the first fixing member 6 is provided with a first groove, and the first interface 41 of the connecting member 4 is matched and connected with the first groove to form a first placement space, and the one-way conducting element 3 is arranged and hidden in the first placement space (as shown in FIG.

[0090] It should be noted that, since there are at least two flow channels, each flow channel includes a first fixing member 6 and a second fixing member 7, the multiple first fixing members 6 and the multiple second fixing members 7 of the multiple flow channels can be formed as one piece or separately. Figure 7 The first fixing member 6 shown is provided in a split form, corresponding to a flow channel alone, for example Figure 8 As shown, the second fixing member 7 is formed by two second fixing members 7 in one piece, which is convenient for processing and installation, and the utility model is not limited to this.
