Abstract
Description
Technical Field
[0001] The present application relates to the technical field of analyzers, and particularly to a liquid replenishing device. Background Art
[0002] For an analyzer used in in vitro diagnosis, it is usually necessary to replenish liquid from an external container into an internal container of the analyzer. Generally, the liquid level in the external container is higher than that in the internal container. After the liquid is replenished from the external container to the internal container through a pipeline by a liquid replenishing pump, the liquid in the external container will still continuously flow into the internal container due to the siphon effect, resulting in the overflow of the liquid in the internal container and thus damaging the analyzer. To avoid the siphon effect, traditional liquid replenishing devices usually have the defect of high manufacturing cost. Summary of the Utility Model
[0003] One technical problem solved by the present application is how to reduce the manufacturing cost of the liquid replenishing device.
[0004] A liquid replenishing device is used in conjunction with an external container and an internal container. The liquid replenishing device includes:
[0005] A flow-through pipe, including a liquid inlet pipe, a first liquid outlet pipe, and a second liquid outlet pipe. The liquid inlet pipe is inserted into the liquid in the external container, and at least one of the first liquid outlet pipe and the second liquid outlet pipe is located outside the liquid in the internal container; and
[0006] A liquid replenishing pump is arranged on the flow-through pipe. The liquid replenishing pump is used to pump the liquid in the external container into the liquid inlet pipe and pump the liquid from the first liquid outlet pipe and the second liquid outlet pipe into the internal container.
[0007] In one embodiment, the first liquid outlet pipe is located outside the liquid in the internal container, and the second liquid outlet pipe is inserted into the liquid in the internal container.
[0008] In one embodiment, the flow-through pipe further includes a three-way pipe. The three-way pipe includes a first pipe, a second pipe, and a third pipe whose ends are connected to each other. The other end of the first pipe is connected to the first liquid outlet pipe, the other end of the second pipe is connected to the second liquid outlet pipe, and the other end of the third pipe is connected to the liquid inlet pipe.
[0009] In one embodiment, the first pipe and the second pipe are arranged at an angle, and the third pipe forms an equal angle with the angle formed by the first pipe and the second pipe.
[0010] In one embodiment, the first pipe and the second pipe are on the same straight line, and the third pipe is perpendicular to both the first pipe and the second pipe.
[0011] In one embodiment, the second pipe and the third pipe are located on the same straight line, and the first pipe is perpendicular to both the second pipe and the third pipe.
[0012] In one embodiment, the liquid replenishing pump is arranged on the liquid inlet pipe.
[0013] In one embodiment, the liquid replenishing pump is arranged on the first liquid outlet pipe or the second liquid outlet pipe.
[0014] In one embodiment, a one-way valve is further included, and one of the one-way valve and the liquid replenishing pump is located on the first liquid outlet pipe and the other is located on the second liquid outlet pipe.
[0015] In one embodiment, the position where the three-way pipe is located is higher than the liquid level in the external container.
[0016] A technical effect of an embodiment of the present application is that: in view of the fact that at least one of the first liquid outlet pipe and the second liquid outlet pipe is located outside the liquid in the internal container, when the liquid replenishing pump stops working, under the action of atmospheric pressure, the residual liquid in both the first liquid outlet pipe and the second liquid outlet pipe flows into the internal container. At this time, both the first liquid outlet pipe and the second liquid outlet pipe are empty pipes without liquid. In view of the fact that both the first liquid outlet pipe and the second liquid outlet pipe are empty pipes, it will cause the external container and the internal container to not form a communicating vessel through the flow pipe that is not filled with liquid, thereby effectively eliminating the siphon effect caused by forming a communicating vessel and effectively preventing the liquid in the external container from flowing into the internal container through the siphon effect. Therefore, after the liquid replenishing pump stops working, the external container will stop supplying liquid to the internal container, avoiding the overflow of the internal container due to excessive liquid. Therefore, by setting the first liquid outlet pipe and the second liquid outlet pipe, the siphon effect can be effectively avoided, thereby canceling the setting of the solenoid valve with a relatively high cost, and finally reducing the manufacturing cost of the entire liquid replenishing device.

[0027] Refer to Figure 1 , Figure 2 and Figure 3 As shown in Figures 1 to 3 , a liquid replenishing device 10 provided in an embodiment of the present application is applied to an analyzer. The liquid replenishing device 10 is used in conjunction with an external container 21 and an internal container 22. The external container 21 is located outside the analyzer, and the internal container 22 is located inside the analyzer. The liquid replenishing device 10 can pump the liquid in the external container 21 into the internal container 22, thereby compensating the liquid in the internal container 22 and preventing the normal operation of the analyzer from being affected due to insufficient liquid supply in the internal container 22. Of course, sensors can be provided in the external container 21 and the internal container 22. The sensors can monitor the liquid level heights in the external container 21 and the internal container 22 in real time to ensure that the user knows the liquid amounts in the external container 21 and the internal container 22. For example, when the sensor feedbacks that the liquid level height in the external container 21 is too low, liquid can be replenished into the external container 21. When the sensor feedbacks that the liquid level height in the external container 21 is too low, the liquid can be input from the external container 21 into the internal container 22 through the liquid replenishing device 10. When the sensor feedbacks that the liquid level height in the external container 21 exceeds the set value, the liquid replenishing device 10 can be made to stop inputting liquid from the external container 21 into the internal container 22.
[0028] Refer toFigure 1 , Figure 2 and Figure 3 , in some embodiments, the liquid replenishing device 10 includes a circulation pipe 100 and a liquid replenishing pump 200. The circulation pipe 100 includes a liquid inlet pipe 110, a first liquid outlet pipe 121, and a second liquid outlet pipe 122. The liquid inlet pipe 110 is inserted into the liquid in the external container 21 such that the liquid level in the external container 21 submerges the liquid inlet of the liquid inlet pipe 110; at least one of the first liquid outlet pipe 121 and the second liquid outlet pipe 122 is located outside the liquid in the internal container 22, that is, the liquid outlet of at least one of the first liquid outlet pipe 121 and the second liquid outlet pipe 122 is located outside the liquid in the internal container 22 and is not submerged by the liquid. The liquid replenishing pump 200 is provided on the circulation pipe 100. When the liquid replenishing pump 200 operates, the liquid replenishing pump 200 can pump the liquid in the external container 21 into the liquid inlet pipe 110 and pump the liquid in the liquid inlet pipe 110 from the first liquid outlet pipe 121 and the second liquid outlet pipe 122 into the internal container 22, thereby realizing the replenishment of the liquid in the internal container 22 by the liquid replenishing device 10. For example, the first liquid outlet pipe 121 is located outside the liquid in the internal container 22, and the second liquid outlet pipe 122 is inserted into the liquid in the internal container 22, that is, the liquid outlet of the first liquid outlet pipe 121 is located outside the liquid in the internal container 22 and cannot be submerged by the liquid, and the liquid outlet of the second liquid outlet pipe 122 is located in the liquid in the internal container 22 and is submerged by the liquid. In other embodiments, it is possible to make both the first liquid outlet pipe 121 and the second liquid outlet pipe 122 located outside the liquid in the internal container 22, that is, the liquid outlets of both the first liquid outlet pipe 121 and the second liquid outlet pipe 122 are located outside the liquid in the internal container 22 and cannot be submerged by the liquid.
[0029] In some embodiments, the flow pipe 100 may further include a tee pipe 130. The tee pipe 130 includes a first pipe 131, a second pipe 132, and a third pipe 133. One ends of the first pipe 131, the second pipe 132, and the third pipe 133 are connected to each other and converge at one place. The other end of the first pipe 131 is connected to the first liquid outlet pipe 121, the other end of the second pipe 132 is connected to the second liquid outlet pipe 122, and the other end of the third pipe 133 is connected to the liquid inlet pipe 110. The liquid in the liquid inlet pipe 110 can first enter the third pipe 133. A part of the liquid in the third pipe 133 enters the first pipe 131, and another part of the liquid in the third pipe 133 enters the second pipe 132. The liquid in the first pipe 131 enters the inner container 22 through the first liquid outlet pipe 121, and the liquid in the second pipe 132 enters the inner container 22 through the second liquid outlet pipe 122. In this way, the entire flow pipe 100 inputs the liquid in the outer container 21 into the inner container 22, and finally realizes the replenishment of the liquid in the inner container 22. In other embodiments, the tee pipe 130 may not be provided, so that the ends of the first liquid outlet pipe 121 and the second liquid outlet pipe 122 can be directly connected to the liquid inlet pipe 110. Similarly, the entire flow pipe 100 can input the liquid in the outer container 21 into the inner container 22, and finally realizes the replenishment of the liquid in the inner container 22.
[0030] In some embodiments, referring to Figure 1 , for example, the first pipe 131 and the second pipe 132 are arranged at an angle, the opening of the angle formed by the first pipe 131 and the second pipe 132 faces away from the third pipe 133, and the angles formed by the third pipe 133 with the first pipe 131 and the second pipe 132 are equal, that is, the angle between the third pipe 133 and the first pipe 131 is equal to the angle between the third pipe 133 and the second pipe 132. In this way, the entire tee pipe 130 is substantially in a Y shape. Referring to Figure 2 , for another example, the first pipe 131 and the second pipe 132 are on the same straight line, and the third pipe 133 is perpendicular to both the first pipe 131 and the second pipe 132. In this way, the entire tee pipe 130 is substantially in a T shape. Referring to Figure 3 , for still another example, the second pipe 132 and the third pipe 133 are on the same straight line, and the first pipe 131 is perpendicular to both the second pipe 132 and the third pipe 133. In this way, the entire tee pipe 130 is also substantially in a T shape. Therefore, according to the actual layout requirements of the entire flow pipe 100, tee pipes 130 of different shapes can be adopted, so that the layout of the flow pipe 100 meets the needs of different working conditions and improves the applicability of the liquid replenishing device 10 to different application scenarios.
[0031] In some embodiments, referring to Figure 1 and Figure 2 , the liquid replenishing pump 200 can be arranged on the liquid inlet pipe 110. Referring to Figure 3, the liquid supplement pump 200 can also be arranged on the first liquid outlet pipe 121 or the second liquid outlet pipe 122. There are various setting modes for the liquid supplement pump 200, enabling the liquid supplement pump 200 to be arranged on the liquid inlet pipe 110, the first liquid outlet pipe 121 or the second liquid outlet pipe 122 according to actual needs, improving the diversification of the layout of the liquid supplement pump 200, and also improving the applicability of the liquid supplement device 10 to different application scenarios.
[0032] When it is necessary to supplement the liquid in the internal container 22, the liquid supplement pump 200 can be turned on. The liquid supplement pump 200 can pump the liquid in the external container 21 into the liquid inlet pipe 110, and pump the liquid in the liquid inlet pipe 110 into the internal container 22 through the first liquid outlet pipe 121 and the second liquid outlet pipe 122, so as to realize the liquid supplement of the internal container 22 by the liquid supplement device 10. When the first liquid outlet pipe 121 is outside the liquid in the internal container 22 and the second liquid outlet pipe 122 is inserted into the liquid in the internal container 22, when the liquid supplement pump 200 stops working, under the action of atmospheric pressure, the residual liquid in the first liquid outlet pipe 121 will enter the second liquid outlet pipe 122 through the three-way pipe 130, so that the residual liquid in both the first liquid outlet pipe 121 and the second liquid outlet pipe 122 will flow into the internal container 22. At this time, both the first liquid outlet pipe 121 and the second liquid outlet pipe 122 are empty pipes without liquid.
[0033] Generally, the liquid level in the external container is higher than that in the internal container. After the liquid supplement pump is used to supplement the liquid from the external container to the internal container through the flow pipe, the flow pipe is still filled with liquid. In this way, the external container and the internal container form a communicating vessel through the liquid-filled flow pipe. Therefore, even after the liquid supplement pump finishes working, the liquid in the external container will still flow into the internal container through the siphon effect, which will cause the liquid in the internal container to overflow due to excessive liquid. To prevent the liquid in the external container from still supplementing the liquid to the internal container through the siphon effect after the liquid supplement pump stops working, a solenoid valve is set on the flow pipe. When the liquid supplement pump works, the solenoid valve is opened, and the liquid can be input from the external container to the internal container through the flow pipe; when the liquid supplement pump stops working, the solenoid valve is closed, and the solenoid valve can switch the conduction effect of the flow pipe on the liquid, effectively preventing the liquid in the external container from still supplementing the liquid to the internal container through the siphon effect after the liquid supplement pump stops working. Considering that the cost of the solenoid valve is relatively high and professional personnel are also required for installation, it will increase the material cost and installation cost of the liquid supplement device, and ultimately increase the manufacturing cost of the entire liquid supplement device.
[0034] For the liquid replenishing device 10 in the above embodiments, when the liquid replenishing pump 200 stops working, under the action of atmospheric pressure, the residual liquid in the first liquid outlet pipe 121 will enter the second liquid outlet pipe 122 through the three-way pipe 130, so that the residual liquid in both the first liquid outlet pipe 121 and the second liquid outlet pipe 122 will flow into the inner container 22. At this time, both the first liquid outlet pipe 121 and the second liquid outlet pipe 122 are empty pipes without liquid. In view of the fact that both the first liquid outlet pipe 121 and the second liquid outlet pipe 122 are empty pipes, the outer container 21 and the inner container 22 cannot form a communicating vessel through the liquid-filled flow pipe 100, so that the siphon effect caused by the formation of the communicating vessel can be effectively eliminated, and the liquid in the outer container 21 can be effectively prevented from flowing into the inner container 22 through the siphon effect. Therefore, after the liquid replenishing pump 200 stops working, the outer container 21 will stop supplying liquid to the inner container 22, avoiding the overflow of the inner container 22 due to excessive liquid. Therefore, by setting the first liquid outlet pipe 121 and the second liquid outlet pipe 122, the siphon effect can be effectively avoided, so that the setting of the solenoid valve with a high cost can be cancelled, and finally the manufacturing cost of the entire liquid replenishing device 10 can be reduced.
[0035] In some embodiments, the position where the three-way pipe 130 is located is higher than the liquid level in the outer container 21, so that the siphon effect can be more effectively eliminated. The liquid replenishing device 10 may further include a one-way valve 300, and one of the one-way valve 300 and the liquid replenishing pump 200 is located in the first liquid outlet pipe 121 and the other is located in the second liquid outlet pipe 122. For example, when the first liquid outlet pipe 121 is outside the liquid in the inner container 22 and the second liquid outlet pipe 122 is inserted into the liquid in the inner container 22, the one-way valve 300 may be located on the first liquid outlet pipe 121, and the liquid replenishing pump 200 may be located on the second liquid outlet pipe 122. The one-way valve 300 allows liquid to flow unidirectionally, that is, it allows liquid to flow into the inner container 22 through the first liquid outlet pipe 121, but does not allow liquid to flow in the reverse direction. After the liquid replenishing pump 200 stops working, the liquid in both the first liquid outlet pipe 121 and the second liquid outlet pipe 122 can quickly return to the inner container 22, so as to quickly avoid the siphon effect.
[0036] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered that the scope described in this specification.
[0037] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
