[0042] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0043] See also Figure 1 , Figure 2 and Figure 6One embodiment of the present invention discloses a consumables holder 100 for fixing a consumables box 200. The consumables holder 100 includes a holder body 1, a conducting holder 2 disposed in the holder body 1, and a first valve 3 disposed in the conducting holder 2. The first valve 3 can control the on-off of the conducting holder 2. When the first valve 3 is opened, the conducting holder 2 can be connected with the collecting container 300. The conducting holder 2 can connect the holder body 1 with the collecting container 300, so that gas can flow between the two, and liquid can enter the collecting container 300 from the consumables box 200 through the conducting holder 2. The consumables box 200 includes an inserting portion 4 and a connecting portion 5 disposed in the inserting portion 4. The holder body 1 is provided with a hole-shaped structure, and the inserting portion 4 can be inserted into the holder body 1. In the embodiment of the present invention, before the inserting portion 4 is inserted into the holder body 1, the first valve 3 remains closed. After the inserting portion 4 is inserted into the holder body 1, the first valve 3 automatically opens.

[0044] Specifically, see Figure 3 and Figure 6 The first valve 3 includes a fixed valve core 31 and a movable valve body 32, and a communication port 321 is provided in the movable valve body 32. When the first valve 3 is closed, the fixed valve core 31 can close the communication port 321, and when the fixed valve core 31 is separated from the communication port 321, the communication port 321 is opened, thereby opening the first valve 3.

[0045] See also Figure 3 In one scenario, when the insertion portion 4 is inserted into the seat body 1 from the first direction, the communication portion 5 first contacts and docks with the communication port 321 to form a connection. The communication portion 5 continues to move, which will push the movable valve body 32 to move in the first direction. At this time, the communication port 321 is separated from the fixed valve core 31. Since the first valve 3 is in a closed state before the insertion portion 4 is inserted, the fixed valve core 31 blocks the communication port 321 to form a blockage. After the insertion portion 4 is inserted, the communication port 321 is separated from the fixed valve core 31, so that the communication port 321 is opened, and the communication port 321 is connected to the conduction seat 2. That is, after the insertion portion 4 is inserted into the seat body 1 from the first direction, the first valve 3 is automatically opened, and the communication port 321 is connected to the conduction seat 2, so that the consumable box 200 is connected to the collection container 300. After the connection, the negative pressure generated by the system can make the liquid and gas in the consumable box 200 enter the collection container 300.

[0046] See also Figure 5In one scenario, when the insertion portion 4 leaves the seat body 1 in the opposite direction of the first direction, the driving force of the communication portion 5 in the first direction is lost, and the movable valve body 32 can move in the opposite direction of the first direction. At this time, the communication port 321 is close to the fixed valve core 31, and the fixed valve core 31 will block the communication port 321, so that the communication port 321 is isolated from the conductive seat 2, thereby disconnecting the connection between the consumable box 200 and the collection container 300. At the same time, since the communication port 321 is blocked and will not be in an open state, the liquid or gas in the collection container 300 cannot leak out through the communication port 321, and the external unknown objects will not enter the collection container 300 through the communication port 321, which can completely isolate the space in the collection container 300.

[0047] Exemplarily, the first direction is a vertically downward direction, that is, the insertion portion 4 is inserted vertically downward into the seat body 1, and the opposite direction of the first direction is a vertically upward direction.

[0048] The beneficial effects of the embodiments of the present invention are as follows:

[0049] The consumables holder 100 of the embodiment of the present invention is provided with a conducting seat 2 and a first valve 3 disposed in the conducting seat 2, wherein the first valve 3 includes a fixed valve core 31 and a movable valve body 32. When the consumables box 200 is inserted into the consumables holder 100, the connecting portion 5 of the consumables box 200 can push the movable valve body 32 to move, so that the connecting portion 5 is connected with the connecting port 321 in the movable valve body 32, and then connected with the conducting seat 2 through the connecting port 321. The conducting seat 2 can be connected to the collection container 300 to achieve the connecting function. After use, the consumables box 200 is pulled out of the consumables holder 100. At this time, the connecting port 321 can be isolated from the conducting seat 2, which can prevent the liquid or gas in the collection container 300 from overflowing, and can also prevent unknown objects from entering the collection container 300, achieving the effect of sealing and isolation.

[0050] See also Figure 3In some embodiments, the first valve 3 further includes an elastic member 33 and a fixed valve body 34, wherein the fixed valve body 34 is disposed in the conducting seat 2, and the elastic member 33 is disposed between the fixed valve body 34 and the movable valve body 32. The fixed valve body 34 is stationary relative to the conducting seat 2, and the fixed valve core 31 is stationary relative to the conducting seat 2. When the movable valve body 32 moves toward the first direction, the driving force of the connecting portion 5 is greater than the elastic force of the elastic member 33, and the movable valve body 32 approaches the fixed valve body 34 and puts the elastic member 33 in a compressed state. After the connecting portion 5 is inserted, the movable valve body 32 is fixed, the elastic member 33 is in a compressed state, and the connecting port 321 is opened. When the insertion portion 4 leaves the seat body 1 in the direction opposite to the first direction, the movable valve body 32 loses the driving force of the communication portion 5, and under the action of the elastic restoring force, the elastic member 33 can drive the movable valve body 32 to move in the direction opposite to the first direction, thereby pushing the movable valve body 32 to the initial position, so that the fixed valve core 31 blocks the communication port 321. The elastic member 33 can be a compressible and elastic element such as a spring or an elastic sponge.

[0051] See also Figure 3 In some embodiments, in order to form a seal on the communicating port 321, a sealing portion 311 is provided on the fixed valve core 31, and the sealing portion 311 is located at the upper position of the fixed valve core 31. The sealing portion 311 extends from the side wall of the fixed valve core 31 in a direction away from the central axis of the fixed valve core 31 to form a larger covering surface. The outer edge diameter of the sealing portion 311 is larger than the maximum diameter of the communicating port 321, so that the sealing portion 311 can cover and seal the communicating port 321 when it abuts against the communicating port 321.

[0052] In some embodiments, the movable valve body 32 further includes a sliding portion 322, a connecting hole 3221 is provided in the sliding portion 322, the connecting port 321 is provided at one end of the connecting hole 3221 and is connected to the connecting hole 3221, and the connecting hole 3221 is used to enable the connecting port 321 to be connected to the outlet of the conduction seat 2. The fixed valve body 34 includes a guide portion 341, a guide hole 3411 is provided in the guide portion 341, and the sliding portion 322 is penetrated in the guide hole 3411. When the movable valve body 32 moves in the first direction or the opposite direction of the first direction, the sliding portion 322 can move in the guide hole 3411. The guide hole 3411 not only forms a sliding guide for the sliding portion 322, but also can be connected to the connecting hole 3221, so that the connecting port 321 can be connected to the outlet of the conduction seat 2 through the guide hole 3411.

[0053] See also Figure 6 In some embodiments, in order to form a tighter seal on the communication port 321, the side wall of the fixed valve core 31 is further provided with a first sealing groove 312, and a first sealing ring 35 is provided on the first sealing groove 312, and the first sealing ring 35 can abut against the side wall of the communication hole 3221. In the scenario where the consumable box 200 does not need to be inserted, the sealing portion 311 and the first sealing ring 35 can form a tight seal on the communication port 321 to prevent the liquid or gas in the collection container 300 from overflowing, and has a better sealing and protective effect.

[0054] Further, see Figure 6 , a first inclined surface 313 is further provided between the first sealing groove 312 and the sealing portion 311, and a second inclined surface 323 is provided at the inner edge of the communication port 321, and the positions of the first inclined surface 313 and the second inclined surface 323 correspond to each other. The diameters of the first inclined surface 313 and the second inclined surface 323 gradually decrease along the first direction. When the communication port 321 is sealed, the first inclined surface 313 can abut against the second inclined surface 323. By providing the first inclined surface 313 and the second inclined surface 323, the first sealing ring 35 can easily enter the communication hole 3221 by using the second inclined surface 323, and the abutment between the inclined surfaces does not require a high matching accuracy. Even if there is a processing error between the sealing portion 311 and the communication hole 3221, it is convenient for the sealing portion 311 to abut against the edge of the communication port 321, thereby forming a seamless seal.

[0055] Furthermore, a sealing surface 314 is provided between the first inclined surface 313 and the outer edge of the sealing portion 311 , and the sealing surface 314 can abut against the outer edge of the communicating hole 3221 , and the sealing surface 314 can ensure full coverage and sealing of the communicating hole 321 .

[0056] See also Figure 4In some embodiments, the movable valve body 32 further includes an abutment portion 324, which extends from the end of the sliding portion 322 in a direction away from the central axis of the sliding portion 322. The abutment portion 324 is provided at one end of the sliding portion 322 away from the fixed valve body 34, and the communication portion 5 can abut against the abutment portion 324 after being inserted. A receiving groove 3241 is provided in the abutment portion 324, and the interior of the communication portion 5 can be connected to the receiving groove 3241, and the communication port 321 is provided in the receiving groove 3241. Therefore, in some embodiments, the receiving groove 3241, the communication hole 3221 and the guide hole 3411 form a channel connected between the consumable box 200 and the outlet of the conductive seat 2. When the insertion portion 4 is inserted into the seat body 1 from the first direction, the communication portion 5 can push the abutment portion 324 to move from the first direction and make the communication portion 5 communicate with the receiving groove 3241.

[0057] In addition, a limiting step 36 is formed between the abutting portion 324 and the sliding portion 322, and one end of the elastic member 33 abuts against the limiting step 36, so that the elastic member 33 can use elastic restoring force to push the movable valve body 32. The limiting step 36 can limit the moving stroke of the movable valve body 32. After the movable valve body 32 moves a certain distance in the first direction, the end of the limiting portion can abut against the limiting step 36, and the limiting step 36 can limit the continued movement of the movable valve body 32 in the first direction, thereby achieving a limiting effect.

[0058] In some embodiments, a fixing hole 21 is provided in the conducting seat 2, and the fixed valve body 34 and the movable valve body 32 are both provided in the fixing hole 21, and the movable valve body 32 moves in the fixing hole 21. The fixed valve body 34 also includes a fixing portion 342, and the fixing portion 342 is fixed in the fixing hole 21. The fixing hole 21 forms a fixing effect on the fixed valve body 34, and can resist the elastic force from the elastic member 33. When the insertion portion 4 is inserted into the seat body 1 from the first direction, the connecting portion 5 can be inserted into the fixing hole 21 from the first direction and push the movable valve body 32. One end of the elastic member 33 abuts on the fixing portion 342. Therefore, in some embodiments, one end of the elastic member 33 abuts on the limiting step 36, and the other end of the elastic member 33 abuts on the fixing portion 342.

At the same time, the movable column 731 can move a certain distance in the movable hole 722 to adapt to the squeeze space generated when the second valve 7 is engaged with the receiving groove 3241. The closing piece 732 extends from the movable column 731 in a direction away from the central axis of the movable column 731 and can seal and cover the connecting hole 3221. When the second valve 7 is closed, the closing piece 732 forms a sealing cover on the connecting hole 3221, and when the system generates negative pressure, under the action of the pressure difference, the closing piece 732 is deformed or bent relative to the movable column 731, so that the connecting hole 3221 is exposed. At this time, the second valve 7 is opened, and the connecting hole 3221 is connected with the receiving groove 3241.

[0068] When the insertion portion 4 is inserted into the seat body 1 from the first direction, the movable column 731 abuts against the sealing portion 311 of the fixed valve core 31. After the movable column 731 abuts against the sealing portion 311, the closing piece 732 is more likely to deform or bend, so that the second valve 7 is easy to open for communication.
