Description

TECHNICAL FIELD

[0001] The utility model relates to a medicine adding and mixing device. BACKGROUND

[0002] In the current chemical analysis, environmental monitoring and water quality detection fields, the processing of test liquid and sample analysis are crucial links. The traditional test liquid processing method often relies on manual operation, which is not only inefficient, but also difficult to ensure the accurate mixing ratio of test liquid and required reagent, thereby affecting the final analysis result.

[0003] To solve the above problems, some automatic or semi-automatic test liquid processing equipment has appeared in the market. These devices usually include a container for storing test liquid, a pump for pumping test liquid, and a mixing device for mixing test liquid and reagent. However, these devices still have some deficiencies in practical application.

[0004] For example, some existing devices often use simple stirring or spraying methods when mixing test liquid and reagent, which not only has low mixing efficiency, but also easily leads to uneven distribution of reagent, affecting the mixing effect. In addition, it is worth noting that the existing devices usually need an additional power source to drive the reagent into the mixing device when mixing the test liquid and the reagent, which increases the complexity and cost of the device. SUMMARY

[0005] To solve the above technical problems, the utility model provides a medicine adding and mixing device, which is simple in structure and easy to operate. By utilizing the low pressure effect generated by the test liquid during high-speed flow, the reagent is automatically sucked into the mixer and mixed with the test liquid, which not only improves the mixing effect, but also reduces the equipment cost.

[0006] To achieve the above purpose, the technical scheme of the utility model is as follows:

[0007] The utility model provides a medicine adding and mixing device, which comprises a mixer, an input port and a medicine adding port are arranged on the mixer, the input port is connected with a test liquid storage through a first pipeline, a water pump is connected on the first pipeline, and the medicine adding port is connected with a reagent storage through a second pipeline.

[0008] The utility model provides a medicine adding and mixing device, which is simple in structure and easy to operate. By utilizing the low pressure effect generated by the test liquid during high-speed flow, the reagent is automatically sucked into the mixer and mixed with the test liquid, which not only improves the mixing effect, but also reduces the equipment cost.

[0009] Preferably, the mixer is provided with an output port, the input port and the output port are arranged on two sides of the mixer, and the output port is arranged opposite to the input port.

[0010] Preferably, the dosing port is arranged at one end of the mixer.

[0011] Preferably, the radial dimension of the input port gradually decreases towards the inner cavity of the mixer close to the dosing port.

[0012] Preferably, the radial dimension of the output port gradually decreases towards the inner cavity of the mixer close to the dosing port.

[0013] Preferably, the radial dimension of the inner cavity of the mixer at the position of the dosing port is the smallest.

[0014] Preferably, the output port is connected to the flow cell through a third pipeline.

[0015] Preferably, the first pipeline is connected to the input port through a first pipe joint.

[0016] Preferably, the output port is connected to the third pipeline through a second pipe joint.

[0017] Preferably, the flow cell is connected to the third pipeline through a third pipe joint.

[0018] The mixing device has the following advantages:

[0019] 1) The device has simple structure and is easy to operate, and the low pressure effect generated by the test liquid in high-speed flow is used to automatically suck the liquid medicine into the mixer and mix with the test liquid, thereby improving the mixing effect and reducing the equipment cost.

[0020] 2) The water pump draws the test liquid from the test liquid storage through the first pipeline and sends it into the input port of the mixer at high speed; during high-speed flow, the static pressure energy of the test liquid decreases according to Bernoulli equation, thereby forming a low pressure area inside the mixer; due to the pressure difference between the low pressure area formed inside the mixer and the liquid medicine in the liquid medicine storage, the pressure difference drives the liquid medicine to be sucked into the mixer through the second pipeline; under the action of the pressure difference, the liquid medicine is sucked into the inner part of the mixer and mixed with the test liquid flowing at high speed; once the liquid medicine is sucked into the mixer, it is mixed with the test liquid inside the mixer, thereby improving the mixing effect and reducing the equipment cost.

[0025] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0026] It should be noted that the terms "first", "second", and "third" and the like in the description and claims of the present application and above drawings are used only to distinguish similar objects, and do not necessarily have to be used to describe a particular order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0027] As Figures 1-3 shown, the present application provides a dosing mixing device comprising: a mixer 1, the mixer 1 is provided with an input port 4 and a dosing port 6, the input port 4 is connected with a test liquid reservoir 2 through a first pipeline 3, the first pipeline 3 is connected with a water pump 14, the dosing port 6 is connected with a liquid medicine reservoir 8 through a second pipeline 7.

[0028] The present application provides a dosing mixing device, which has simple structure and is convenient to operate, and by using the low pressure effect generated by the test liquid in the high-speed flow process, the liquid medicine is automatically sucked into the mixer and mixed with the test liquid, which not only improves the mixing effect, but also reduces the equipment cost.

[0029] Preferably, as Figure 3 shown, the mixer 1 is provided with an output port 5, and the output port 5 is arranged corresponding to the input port 4; the output port 5 and the input port 4 are arranged corresponding to each other, which can ensure that the test liquid (and the liquid medicine sucked in) forms a continuous flow path inside the mixer 1; this helps to reduce the resistance and energy consumption of the fluid during the mixing process, and improves the mixing efficiency.

[0030] Preferably, asFigure 3 As shown, the input port 4 and the output port 5 are arranged on both sides of the mixer 1, and the dosing port 6 is arranged at one end of the mixer 1; the test liquid enters the mixer 1 from one side, and flows out from the other side after mixing, which helps to ensure that the test liquid is fully mixed inside the mixer 1, improving mixing uniformity; the dosing port 6 is arranged at one end of the mixer 1, and when the test liquid flows at high speed through the input port, a low-pressure area is formed inside the mixer 1; there is a pressure difference between this low-pressure area and the drug liquid in the drug liquid reservoir, thereby driving the drug liquid to be sucked into the mixer 1; this design cleverly utilizes the Venturi effect in fluid dynamics to achieve automatic suction of the drug liquid; since the dosing port 6 is located at one end of the mixer 1, the drug liquid is quickly mixed with the test liquid flowing at high speed after being sucked in; this design helps to ensure uniform distribution of the drug liquid inside the mixer 1, avoiding local over-concentration or under-concentration.

[0031] Preferably, as shown in Figure 3 The radial dimension of the input port 4 gradually decreases towards the inner cavity of the mixer 1 near the dosing port 6; the radial dimension of the input port 4 gradually decreases towards the dosing port 6, which helps to accelerate the inflow of the test liquid and produce a certain jet effect; when the test liquid enters the mixer at high speed, its kinetic energy increases, which helps to form a turbulent flow inside the mixer 1, promoting the mixing of the test liquid and the drug liquid.

[0032] Preferably, as shown in Figure 3 The radial dimension of the output port 5 gradually decreases towards the inner cavity of the mixer 1 near the dosing port 6; the radial dimension of the output port 5 gradually decreases towards the dosing port 6, which can ensure that the mixed liquid flows out of the mixer 1 at a high flow rate and pressure, facilitating subsequent processing or analysis.

[0033] Preferably, as shown in Figure 3 The radial dimension of the inner cavity of the mixer 1 at the position of the dosing port 6 is the smallest; the dosing port 6 is arranged at one end of the mixer 1, and at this position, the radial dimension of the inner cavity of the mixer 1 is the smallest; this design utilizes the Venturi effect in fluid dynamics, i.e. when fluid flows through a narrow area, the flow rate increases, and the static pressure decreases; therefore, a low-pressure area is formed near the dosing port 6, and there is a pressure difference between this low-pressure area and the drug liquid in the drug liquid bottle, thereby driving the drug liquid to be sucked into the mixer 1.

[0034] Preferably, as shown in Figures 1-2 The output port 5 is connected to the flow cell 10 through a third pipeline 9; this ensures that the mixed fluid can continuously and stably flow into the flow cell 10.

[0035] Preferably, as shown in Figures 1-2As shown, comprising: the first pipe joint 11, the input port 4 is connected with the first pipe 3 through the first pipe joint 11; the first pipe joint 11 guarantees the stability of the connection between the input port 4 and the first pipe 3, and facilitates installation and maintenance.

[0036] Preferably, as Figures 1-2 As shown, comprising: the second pipe joint 12, the output port 5 is connected with one end of the third pipe 9 through the second pipe joint 12; the second pipe joint 12 guarantees the stability of the connection between the output port 5 and the third pipe 9, and facilitates installation and maintenance.

[0037] Preferably, as Figures 1-2 As shown, comprising: the third pipe joint 13, the flow cell 10 is connected with the other end of the third pipe 9 through the third pipe joint 13; the third pipe joint 13 guarantees the stability of the connection between the third pipe 9 and the flow cell 10, and facilitates installation and maintenance.
