[0030] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0031] Example 1

[0032] refer to Figure 1 As shown, an embodiment of the present application provides a liquid outlet structure 100 , which includes a tank body 110 , a first liquid outlet channel 120 , a second liquid outlet channel 130 and a first reversing valve 140 .

[0033] Specifically, combined Figure 1 and Figure 2As shown, the tank body 110 is provided with a first liquid outlet 111 and a second liquid outlet 112, the height of the first liquid outlet 111 is greater than the height of the second liquid outlet 112; one end of the first liquid outlet channel 120 is connected to the first liquid outlet 111; one end of the second liquid outlet channel 130 is connected to the second liquid outlet 112; the first reversing valve 140 includes a first interface 141, a second interface 142 and a third interface 143, the first interface 141 is connected to an end of the first liquid outlet channel 120 away from the first liquid outlet 111, the second interface 142 is connected to an end of the second liquid outlet channel 130 away from the second liquid outlet 112, and the third interface 143 is used to discharge the liquid so that The first reversing valve 140 can control the connection or closure of the first liquid outlet channel 120, and / or the first reversing valve 140 can control the connection or closure of the second liquid outlet channel 130. Accordingly, the height of the first liquid outlet 111 is greater than the height of the second liquid outlet 112, and the drug residue will settle below the height of the first liquid outlet 111. The first liquid outlet 111 can facilitate the discharge of the liquid medicine product, reduce the residual drug residue when the liquid medicine is discharged, and facilitate the precipitation and separation of the liquid medicine and the drug residue. When the liquid medicine product does not have high requirements for the residual drug residue and other sediments, the second liquid outlet 112 can be used to discharge the liquid through the first liquid outlet 111 and the second liquid outlet 112 at the same time, thereby improving the discharge efficiency and facilitating the switching of different discharge methods according to different liquid medicine products.

[0034] It should be noted that the staff can control the first liquid outlet 111 on the tank body 110 to open or close, and control the second liquid outlet 112 on the tank body 110 to open or close. The first reversing valve 140 or the second reversing valve 131 is a directional control valve with two or more flow forms and two or more liquids, and is a valve that realizes the flow, cutoff and reversal of liquids, as well as pressure unloading and sequential action control. The valve core can be operated in one or a combination of manual, motorized, electric, hydraulic, electro-hydraulic and other modes.

[0035] In one embodiment, optionally, Figure 1 As shown, the second liquid outlet channel 130 also includes a second reversing valve 131, and the second reversing valve 131 includes a fourth interface 1311. The fourth interface 1311 is connected to the third liquid outlet 113 through the third liquid outlet channel 150. Accordingly, the second reversing valve 131 can control the opening or closing of the fourth interface 1311. The tank body 110 is also provided with a third liquid outlet 113, which can allow the liquid medicine exceeding the height of the third liquid outlet 113 to flow into the third liquid outlet channel 150 through the third liquid outlet 113.

[0036] Furthermore, the height of the third liquid outlet 113 is greater than the height of the first liquid outlet 111. When the height of the medicinal liquid in the tank body 110 exceeds a preset height, the medicinal liquid exceeding the preset height can flow out through the third liquid outlet 113 to avoid overflow of the medicinal liquid in the tank body 110. The second reversing valve 131 is used to achieve the confluence and discharge of the medicinal liquid in the third liquid outlet 113 and the second liquid outlet 112.

[0037] Optionally, refer to Figure 1 As shown, the third liquid outlet 113 is located near the upper position of the tank body 110, and a liquid inlet is provided at the upper position of the tank body 110. The third liquid outlet 113 is located close to the liquid inlet of the tank body 110 to prevent the liquid in the tank body 110 from being too high and overflowing from the liquid inlet.

[0038] In one embodiment, optionally, reference Figure 2 As shown, the first liquid outlet 111 is located at the side of the tank body 110, and the second liquid outlet 112 is located at the bottom of the tank body 110. The drug residue will settle below the height of the first liquid outlet 111. The first liquid outlet 111 can facilitate the discharge of the liquid drug product, reduce the residual drug residue when the liquid drug is discharged, and facilitate switching the first liquid outlet 111 and the second liquid outlet 112 according to different liquid drug products. Accordingly, when the liquid drug product has low requirements for residual drug residue and other sediments, the liquid can be discharged through the second liquid outlet 112, and the liquid can also be discharged through the first liquid outlet 111 and the second liquid outlet 112, thereby improving the discharge efficiency.

[0039] In one embodiment, optionally, Figure 1 As shown, the tank body 110 defines a accommodating cavity 114, and the accommodating cavity 114 includes a first accommodating space 1141 and a second accommodating space 1142. The first accommodating space 1141 and the second accommodating space 1142 are arranged in sequence along a first direction, the first liquid outlet 111 is arranged in the first accommodating space 1141, and the second liquid outlet 112 is arranged in the second accommodating space 1142. The liquid discharge is achieved through the first liquid outlet 111 of the first accommodating space 1141.

[0040] In summary, the height of the first liquid outlet 111 of the liquid outlet structure 100 is greater than the height of the second liquid outlet 112, and the drug residue will settle below the height of the first liquid outlet 111. The first liquid outlet 111 can facilitate the discharge of the liquid medicine product, reduce the situation of residual drug residue when the liquid medicine is discharged, and is beneficial to the precipitation and separation of the liquid medicine and the drug residue. When the liquid medicine product does not have high requirements for residual drug residue and other sediments, the second liquid outlet 112 can be used to discharge the liquid at the same time, thereby improving the liquid discharge efficiency and facilitating the staff to switch to different liquid discharge methods according to different liquid medicine products, thereby improving the adaptability and versatility of the liquid outlet structure 100.

[0041] Example 2

[0042] refer to Figure 1 As shown, an embodiment of the present application provides another liquid outlet structure 100 , which includes a tank body 110 , a first liquid outlet channel 120 , a second liquid outlet channel 130 and a first reversing valve 140 .

[0043] Specifically, combined Figure 1 and Figure 2 As shown, the tank body 110 is provided with a first liquid outlet 111 and a second liquid outlet 112, and the height of the first liquid outlet 111 is greater than the height of the second liquid outlet 112; one end of the first liquid outlet channel 120 is connected to the first liquid outlet 111; one end of the second liquid outlet channel 130 is connected to the second liquid outlet 112, and the height of the first liquid outlet 111 is greater than the height of the second liquid outlet 112. The drug residue will settle below the height of the first liquid outlet 111, and the first liquid outlet 111 can facilitate the discharge of the drug liquid product, reduce the situation of residual drug residue when the drug liquid is discharged, and is conducive to the precipitation and separation of the drug liquid and the drug residue.

[0044] In this embodiment, the first reversing valve 140 includes a first interface 141, a second interface 142 and a third interface 143, the first interface 141 is connected to the end of the first liquid outlet channel 120 away from the first liquid outlet port 111, the second interface 142 is connected to the end of the second liquid outlet channel 130 away from the second liquid outlet port 112, and the third interface 143 is used to discharge the liquid so that the first reversing valve 140 can control the connection or closure of the first liquid outlet channel 120, and / or the first reversing valve 140 can control the connection or closure of the second liquid outlet channel 130. Accordingly, when the medicinal liquid product has low requirements on sediments such as residual medicinal residues, liquid can be discharged through the first liquid outlet 111 and the second liquid outlet 112 at the same time through the second liquid outlet 112, thereby improving the liquid discharge efficiency and facilitating switching of different liquid discharge methods according to different medicinal liquid products.

[0045] Exemplarily, the first liquid outlet channel 120 or the second liquid outlet channel 130 can both use a hose, which is made of silicone tube, polyvinylidene fluoride tube, PTFE tube, etc., has better high temperature resistance and corrosion resistance, long service life, and reduces the impact on the purity, safety and hose transmission efficiency of the drug.

[0046] In one embodiment, optionally, Figure 1 As shown, the second liquid outlet channel 130 also includes a second reversing valve 131, and the second reversing valve 131 includes a fourth interface 1311, and the fourth interface 1311 is connected to the third liquid outlet 113 through the third liquid outlet channel 150. Accordingly, the second reversing valve 131 can control the opening or closing of the fourth interface 1311. The tank body 110 is also provided with a third liquid outlet 113, which can flow the liquid exceeding the height of the third liquid outlet 113 into the third liquid outlet channel 150 through the third liquid outlet 113. It should be noted that the second liquid outlet channel 130 can be connected and transmitted to the second interface 142 of the first reversing valve 140 through the second reversing valve 131. Exemplarily, the second reversing valve 131 is located below the second liquid outlet 112.

[0047] Furthermore, the height of the third liquid outlet 113 is greater than the height of the first liquid outlet 111. When the height of the medicinal liquid in the tank body 110 exceeds a preset height, the medicinal liquid exceeding the preset height can flow out through the third liquid outlet 113 to avoid overflow of the medicinal liquid in the tank body 110. The second reversing valve 131 is used to realize the confluence and discharge of the medicinal liquid in the third liquid outlet 113 and the second liquid outlet 112. The medicinal liquid flowing out of the third liquid outlet 113 can also be utilized, thereby reducing the waste of medicinal liquid.

[0048] Optionally, refer to Figure 1 As shown, the third liquid outlet 113 is located near the upper part of the tank body 110. Exemplarily, a liquid inlet is provided at the upper part of the tank body 110, and the third liquid outlet 113 is located near the liquid inlet of the tank body 110 to prevent the liquid in the tank body 110 from overflowing from the liquid inlet due to excessive height.

[0049] Alternatively, if Figure 1 As shown, the second reversing valve 131 also includes a fifth interface 1312, which is connected to a drain pipe and is used to allow residual impurities in the tank body 110 to be discharged through the drain pipe when the tank body 110 is cleaned. Accordingly, the second reversing valve 131 can control the opening or closing of the fifth interface 1312.

[0050] In one embodiment, optionally, the first reversing valve 140 is a three-way valve, and the second reversing valve 131 is a four-way valve. The three-way valve or the four-way valve is a fluid control valve, which can be applied to the liquid outlet channel of the liquid outlet structure 100, and a plurality of interfaces are correspondingly provided so as to be able to connect a plurality of liquid outlet channels, which is used to adjust or change the flow direction of the medium, and can realize different flow paths.

[0051] In one embodiment, optionally, reference Figure 2 As shown, the first liquid outlet 111 is located at the side of the tank body 110, and the second liquid outlet 112 is located at the bottom of the tank body 110. The drug residue will settle below the height of the first liquid outlet 111. The first liquid outlet 111 can facilitate the discharge of the liquid medicine product, reduce the residual drug residue when the liquid medicine is discharged, and facilitate switching the first liquid outlet 111 and the second liquid outlet 112 according to different liquid medicine products. Accordingly, when the liquid medicine product has low requirements for residual drug residue and other sediments, the liquid can be discharged through the second liquid outlet 112, and the liquid can also be discharged through the first liquid outlet 111 and the second liquid outlet 112, thereby improving the discharge efficiency. The second liquid outlet 112 at the bottom of the tank body 110 can make all the liquid medicine in the tank body 110 flow out, avoiding the residual liquid medicine in the tank body 110.

[0052] In one embodiment, optionally, Figure 1 As shown, the tank body 110 defines a accommodating cavity 114, and the accommodating cavity 114 includes a first accommodating space 1141 and a second accommodating space 1142. The first accommodating space 1141 and the second accommodating space 1142 are arranged in sequence along a first direction, and the first liquid outlet 111 is arranged in the first accommodating space 1141, and the second liquid outlet 112 is arranged in the second accommodating space 1142. It can be understood that the second accommodating space 1142 is located below the first accommodating space 1141, and the second accommodating space 1142 is used to precipitate sediments such as medicinal residues in the medicinal solution, and the medicinal solution is discharged through the first liquid outlet 111 of the first accommodating space 1141.

[0053] In one embodiment, optionally, the inner diameter of the first liquid outlet 111 is D1, and the inner diameter of the first liquid outlet channel 120 is D2, which satisfies: 0.5D2≤D1<D2, that is, the inner diameter D1 of the first liquid outlet 111 is smaller than the inner diameter D2 of the first liquid outlet channel 120, and the size of the first liquid outlet channel 120 is increased to provide a higher fluid capacity, which helps to reduce the resistance of fluid flow, improve the liquid discharge efficiency, and reduce the risk of blockage of the first liquid outlet channel 120. For example, D1 is 49 mm and D2 is 50 mm. The inner diameter D1 of the first liquid outlet 111 is greater than or equal to 0.5D2 of the inner diameter of the first liquid outlet channel 120, which reduces the situation where the inner diameter D1 of the first liquid outlet 111 is too small, causing the inner diameter D2 of the first liquid outlet channel 120 to be difficult to adapt, and the inner diameter D2 of the first liquid outlet channel 120 is too large, causing material waste. In addition, D1 can also be 25 mm and D2 can be 50 mm. Of course, the sizes of D1 and D2 are not limited to this. In other embodiments, when D1 is 20 mm, D2 may also be 40 mm; when D1 is 30 mm, D2 may also be 31 mm, 35 mm, 40 mm, 50 mm, 60 mm, etc., which are not listed here one by one.

The design and manufacture of this tank body 110 need to follow strict standards and specifications to ensure the safety and stability of the medicine liquid during the storage process. The medicine liquid storage tank 200 can use the liquid outlet structure 100 to discharge the liquid. The medicine liquid storage tank 200 includes the liquid outlet structure 100 in Example 1 or Example 2. The medicine liquid storage tank 200 has all the beneficial effects of the liquid outlet structure 100, which will not be described in detail here.

[0056] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.
