Description

Technical Field

[0001] The present invention relates to the technical field of liquid storage and infusion devices, and in particular to a highly integrated liquid storage and infusion device, and application equipment comprising the highly integrated liquid storage and infusion device. Background Art

[0002] As electronic, electromechanical, and optoelectronic products gradually develop towards miniaturization and sophistication, compact structural design occupies an increasingly important proportion in the product design process. Limited space has brought difficulties to the coordinated arrangement of structures and functions between various product components, especially when liquid storage and fluid transportation are involved in a small space. Traditional liquid storage and fluid delivery devices usually use infusion tubes to connect discretely arranged liquid storage chambers and fluid-driven pumps. The integration is not high and the space occupied is large. At the same time, seals must be set at the connection joints of the infusion tubes to prevent leakage, and the structure is relatively complex. In improved technologies, it is usually considered to integrate the liquid storage chamber and the infusion pipeline, and at the same time set a connection interface for the fluid-driven pump, and then fix the fluid pump thereon. This method improves the overall integration to a certain extent and saves space, but is only suitable for occasions where the fluid flow path is relatively simple. It is difficult to implement when the flow path has bends, diameter changes, and multi-path combinations. Even if it can be implemented, it will cause a significant increase in cost. At the same time, the liquid storage chamber is mostly surrounded by a material with relatively high rigidity. When the outer shape of the narrow space is complex, the liquid storage chamber does not fit the outer shape of the narrow space well, resulting in space waste and even difficulty in ensuring the designed capacity of the liquid storage chamber. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problems of low integration, large space occupation, difficulty in molding and low space utilization in the liquid storage and infusion devices in the prior art, a highly integrated liquid storage and infusion device and an application device including the above-mentioned highly integrated liquid storage and infusion device are provided.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a highly integrated liquid storage and infusion device, comprising:

[0005] A flow channel, wherein the interior of the flow channel has an infusion channel and a liquid supply channel, and the surface of the flow channel has an infusion inlet, an infusion outlet, a liquid supply inlet and a liquid supply outlet, wherein the infusion inlet and the infusion outlet are both connected to the infusion channel, and the liquid supply inlet and the liquid supply outlet are both connected to the liquid supply channel;

[0006] A flexible membrane is arranged on the flow channel and forms a liquid storage cavity with the surface of the flow channel, wherein the liquid storage cavity is provided with a liquid injection port connected thereto, and the liquid inlet is connected to the liquid storage cavity;

[0007] And a power pump is arranged on the flow channel, the inlet of the power pump is connected with the infusion outlet, and the outlet of the power pump is connected with the liquid supply inlet.

[0008] In this solution, an infusion channel and a liquid supply channel are opened inside the flow channel body, and an integrated design is made for the liquid transportation and flow path. The liquid storage cavity formed by the flexible membrane and the flow channel can be highly fitted with the outer contour of the applicable space, thereby increasing the liquid storage capacity and having high space utilization. It can meet the application requirements of fluid transportation in a narrow space, greatly reducing the space occupied by the liquid storage and infusion device, and facilitating layout. It has a significant improvement in the structural compactness for complex flow path scenarios, is easy to form, has a simple structure, is low in cost, and has good market prospects.

[0009] In order to avoid the internal stress of the flexible membrane itself from compressing the liquid in the liquid storage chamber, which may affect the delivery flow accuracy when the power pump pumps out the liquid in the liquid storage chamber, and to avoid the problem that when replenishing the liquid in the liquid storage chamber, the internal stress of the flexible membrane itself needs to be overcome to make it bulge, which may lead to difficulty in replenishing the liquid, in view of this, further, the flexible membrane adopts a flexible membrane that eliminates or reduces the internal stress in a fixed state, and the fixed state is a state when the liquid in the flexible chamber forces the flexible membrane to bulge to fit the outer contour of the applicable space;

[0010] By adopting a flexible membrane that is shaped according to a standard and eliminates or reduces internal stress, the liquid storage cavity will not be affected by the internal stress of the flexible membrane itself during the process of infusion or fluid replenishment, thereby ensuring the accuracy of the delivery flow and achieving easy fluid replenishment. It can also improve the fit between the flexible membrane and the outer contour of the applicable space and increase the liquid storage capacity.

[0011] Furthermore, the inlet of the power pump is directly opposite to the infusion outlet, and the outlet of the power pump is directly opposite to the liquid supply inlet, and the power pump is fixed on the surface of the flow channel, wherein when the power pump is fixed on the surface of the flow channel, the inlet of the power pump and the infusion outlet are butt-jointed and connected, and the outlet of the power pump and the liquid supply inlet are butt-jointed and connected; thereby, when the power pump is fixed on the surface of the flow channel, the power pump can be butt-jointed with the infusion outlet and the liquid supply inlet, thereby achieving a high degree of integration between the power pump and the flow channel, without the need to set up external pipelines separately, facilitating assembly, and improving the degree of integration.

[0012] Furthermore, the infusion inlet is directly opposite to the flexible membrane and is located in the liquid storage cavity; thus, when the flexible membrane is fixed on the surface of the flow channel, the infusion inlet and the liquid storage cavity can be docked, thereby achieving a high degree of integration between the liquid storage cavity and the infusion inlet, facilitating assembly, and improving integration.

[0013] Furthermore, it also includes a flow direction reversing device, which has a reversing channel inside.

[0061] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention, and directions and references (e.g., up, down, left, right, etc.) may only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not to be taken in a limiting sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.

[0062] Example 1

[0063] like Figure 1 , 2 , 5-9, a highly integrated liquid storage and infusion device, comprising:

[0064] The flow channel 1 has an infusion channel 13 and a liquid supply channel 14 inside, and the surface of the flow channel 1 has an infusion inlet 13a, an infusion outlet 13b, a liquid supply inlet 14a and a liquid supply outlet 14b, wherein the infusion inlet 13a and the infusion outlet 13b are both connected to the infusion channel 13, and the liquid supply inlet 14a and the liquid supply outlet 14b are both connected to the liquid supply channel 14;

[0065] The flexible membrane 2 is arranged on the flow channel 1 and forms a liquid storage cavity 3 with the surface of the flow channel 1. The liquid storage cavity 3 is provided with a liquid injection port 6 connected thereto, and the liquid infusion inlet 13a is connected to the liquid storage cavity 3;

[0066] And the power pump 5 is arranged on the flow channel 1, the inlet 51 of the power pump 5 is connected with the infusion outlet 13b, and the outlet 52 of the power pump 5 is connected with the liquid supply inlet 14a.

[0067] In order to prevent the internal stress of the flexible membrane 2 from compressing the liquid in the liquid storage chamber 3, which may affect the delivery flow accuracy when the power pump 5 pumps out the liquid in the liquid storage chamber 3, and to avoid the problem that when replenishing the liquid in the liquid storage chamber 3, the flexible membrane 2 needs to overcome its own internal stress to make it bulge, which may cause difficulty in replenishing the liquid, in view of this, the flexible membrane 2 of this embodiment adopts a flexible membrane 2 that eliminates or reduces the internal stress in a fixed state, and the fixed state is a state when the liquid in the flexible cavity forces the flexible membrane 2 to bulge to fit the outer contour 8 of the applicable space;

[0068] By adopting a flexible membrane 2 that is shaped according to the outer contour 8 of the applicable space and eliminates or reduces internal stress, the liquid storage cavity 3 can be free from the influence of the internal stress of the flexible membrane 2 itself during the process of infusion or fluid replenishment, thereby ensuring the accuracy of the delivery flow and achieving easy fluid replenishment, and being able to improve the fit between the flexible membrane 2 and the outer contour 8 of the applicable space and increase the liquid storage capacity.

[0069] In this embodiment, the internal stress of the flexible film 2 is eliminated or reduced by heat treatment.

[0070] It should be noted that the applicable space outer contour 8 of the liquid storage chamber 3 must be connected to the external environment in which it is located, so that the gas pressure in the applicable space outer contour 8 is balanced with the gas pressure of the external environment, and the deformation of the liquid storage chamber 3 during the injection or infusion process is not affected by the air pressure difference between the applicable space outer contour 8 and the external environment in which it is located, so as to ensure normal infusion.

[0071] In this embodiment, the inlet 51 of the power pump 5 is opposite to the infusion outlet 13b, and the outlet 52 of the power pump 5 is opposite to the liquid supply inlet 14a. The power pump 5 is fixed on the surface of the flow channel 1, wherein when the power pump 5 is fixed on the surface of the flow channel 1, the inlet 51 of the power pump 5 and the infusion outlet 13b are connected to each other, and the outlet 52 of the power pump 5 and the liquid supply inlet 14a are connected to each other; thereby, when the power pump 5 is fixed on the surface of the flow channel 1, the power pump 5 can be connected to the infusion outlet 13b and the liquid supply inlet 14a, thereby realizing a high degree of integration between the power pump 5 and the flow channel 1, without the need to set up external pipelines separately, facilitating assembly and improving the degree of integration.

[0072] In this embodiment, the infusion inlet 13a is directly opposite to the flexible membrane 2 and is located in the liquid storage cavity 3; thus, when the flexible membrane 2 is fixed to the surface of the flow channel 1, the infusion inlet 13a and the liquid storage cavity 3 can be docked, thereby achieving a high degree of integration between the liquid storage cavity 3 and the infusion inlet 13a, facilitating assembly, and improving integration.

[0073] This embodiment also includes a flow direction reversing device 7, which has a reversing channel 71. The surface of the flow direction reversing device 7 is provided with a reversing inlet 71a and a reversing outlet 71b connected to the reversing channel 71. The reversing inlet 71a is connected to the liquid supply outlet 14b, so that the liquid can be diverted and outputted.

[0074] In order to prevent liquid leakage, valves are provided on the outlet 52, liquid supply inlet 14a, liquid supply channel 14, liquid supply outlet 14b, reversing inlet 71a, reversing channel 71 or reversing outlet 71b of the power pump 5 in this embodiment. The valve is a pre-pressure one-way valve or an active microvalve; when the power pump 5 is working, the valve is opened for one-way liquid infusion, and when the power pump 5 is closed, the valve is closed to prevent liquid leakage; the active microvalve is a valve that actively controls the opening and closing.

[0075] In this embodiment, the liquid injection port 6 is arranged on the flexible membrane 2; the liquid is injected into the liquid storage chamber 3 through the liquid injection port 6 and then blocked, such as by plugging the liquid injection port 6 with a plug. Preferably, in this embodiment, the liquid injection port 6 is provided with a one-way valve; so as to realize the one-way injection of liquid into the liquid storage chamber 3 from the outside and the reverse direction is blocked.

[0076] The flow channel 1 of this embodiment is a flow channel 1 that can be bent and shaped; the flow channel 1 is a stacked thin plate / membrane configuration, which can achieve flexible design and layout.

[0077] In this embodiment, the flow channel 1 includes a base 11 and a panel 12 unit;

The base 11 is provided with an infusion groove 11a for forming an infusion channel 13 and a liquid supply groove 11b for forming a liquid supply channel 14. The panel 12 in the panel unit can also be made of a thin plate or a film.

[0079] The infusion tank 11 a and the supply tank 11 b are both blocked by a panel unit to form the infusion channel 13 and the supply channel 14 .

[0080] The infusion groove 11a and the liquid supply groove 11b are both groove structures with an opening on one side of the surface of the base 11. The opening of the infusion groove 11a and the opening of the liquid supply groove 11b are located on the same side of the base 11. The panel unit includes at least one panel 12. The opening of the infusion groove 11a and the opening of the liquid supply groove 11b on the base 11 are covered by the same panel 12 or different panels 12.

[0081] In this embodiment, the power pump 5 is a micro pump used to provide power for liquid transportation. When the power pump 5 is started, the liquid in the liquid storage chamber 3 is transported to the liquid supply channel 14 through the infusion channel 13 and output from the reversing channel 71.

[0082] The micro pump may be a piezoelectric pump, an electrostatic pump, an electromagnetic pump, a peristaltic pump, a plunger pump, or other types of fluid pumps, without limitation herein.

[0083] The micro pump of the present embodiment is preferably a micro piezoelectric pump, which can be formed into a stacked form with extremely small thickness and can be highly integrated with the flow channel 1 without the need for separately setting up external pipelines. It has a compact structure and can adapt to the use requirements of a small heat dissipation space.

[0084] In this embodiment, there is at least one micro pump, which can be determined based on factors such as the flow rate and path of the required liquid delivery.

[0085] like Figure 8 and 9 As shown, in this embodiment, the power pump 5 and the flexible membrane 2 can be located on the same side of the flow channel 1 respectively, or on the same side of the flow channel 1.

[0086] In this embodiment, the number, form, etc. of the infusion channel 13, the liquid supply channel 14, and the reversing channel 71 can be adaptively adjusted according to the specific requirements of the liquid storage and output device (increasing the infusion flow rate and / or performing liquid distribution and delivery, etc.); for example, the infusion channel 13 has one or two or more than two. When the infusion channel 13 is one, the infusion channel 13 is a single-path infusion channel 13 or a bifurcated infusion channel 13. The bifurcated infusion channel 13 includes at least two channels that intersect and communicate with each other, and the bifurcated infusion channel 13 has at least one infusion inlet 13a and one infusion outlet 13b; when there are two or more infusion channels 13, the infusion channels 13 are not connected to each other.

[0087] For example, the liquid supply channel 14 has one or two or more liquid supply channels. When there is one liquid supply channel 14, the liquid supply channel 14 is a single-path liquid supply channel 14 or a bifurcated liquid supply channel 14. The liquid supply and infusion channel 13 includes at least two channels that intersect and communicate with each other, and the bifurcated liquid supply channel 14 has at least one liquid supply inlet 14a and one liquid supply outlet 14b. When there are two or more liquid supply channels 14, the liquid supply channels 14 are not connected to each other.

[0088] For example, the reversing channel 71 has one or two or more reversing channels. When there is one reversing channel 71, the reversing channel 71 is a single-path reversing channel 71 or a forked reversing channel 71. The forked reversing channel 71 includes at least two channels that intersect and connect with each other, and the forked reversing channel 71 has at least one reversing inlet 71a and one reversing outlet 71b. When there are two or more forked reversing channels 71, the forked reversing channels 71 are not connected with each other.

[0089] The material of the flexible film 2 can be a flexible polymer film such as TPU, PU, ​​PET, etc., or a metal or metal oxide film, which is not limited here.

[0090] The substrate 11 and the panel 11 of the flow channel 1 can be made of high molecular polymers such as PET, PPS, PEEK, or thin plates / films such as copper, stainless steel, aluminum alloy, and magnesium alloy.
