[0036] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0037] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0039] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0040] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0041] According to one embodiment of the present application, a pump structure is provided. Figures 1 to 5 As shown, the pump structure includes: a shell 1 and a valve body 2, the shell 1 has a pump chamber 11, the valve body 2 is provided with a first through hole 21, the valve body 2 is provided with a plurality of movable sheets 22 along the circumference of the first through hole 21, the plurality of movable sheets 22 cooperate with each other to close or open the first through hole 21, and the valve body 2 is arranged in the liquid inlet channel 12 of the pump chamber 11 and / or the liquid outlet channel 13 of the pump chamber 11.

[0042] In this example, the valve plate body 2 is arranged in the liquid inlet channel 12 and / or the liquid outlet channel 13 of the pump chamber 11, the valve plate body 2 has a first through hole 21, and the valve plate body 2 is also provided with a plurality of movable plates 22, and the plurality of movable plates 22 are suitable for closing or opening the first through hole 21. By providing a plurality of movable plates 22, the liquid output of the liquid inlet channel 12 and / or the liquid outlet channel 13 can be increased within a limited space, so that the structure of the pump structure is more compact, which is conducive to the miniaturized design of the pump structure.

[0043] like Figure 2 and Figure 5 As shown, the valve plate body 2 is provided with a plurality of movable plates 22 along the circumference of the first through hole 21, and the plurality of movable plates 22 can move in the same direction to open the first through hole 21. By providing a plurality of movable plates 22 to open the first through hole 21, the length of each movable plate 22 can be reduced, and at the same time, the degree of opening of the first through hole 21 can be ensured to meet the flow demand. Thus, the pump structure can be ensured to have a large flow rate in a limited space.

[0044] For example, Figure 1 and Figure 2 As shown, the valve plate body 2 is disposed in the liquid inlet channel 12. When the pump structure is filled with liquid, the pressure of the external liquid can impact the multiple movable plates 22 to move in the same direction to open the first through hole 21, and the liquid enters the pump chamber 11 from the first through hole 21.

[0045] like Figure 1 and Figure 3 As shown, the valve body 2 is arranged in the liquid outlet channel 13. When the pump structure discharges liquid, the liquid in the pump chamber 11 can impact the movable plate 22 of the valve body 2 of the liquid outlet channel 13, so that the movable plate 22 moves in the same direction to open the first through hole 21, and the liquid flows out of the first through hole 21 to the pump chamber 11.

[0046] In this example, if Figures 1 to 3 As shown, the valve plate body 2 is disposed in both the liquid outlet channel 13 and the liquid inlet channel 12, so as to make the pump structure more compact, which is beneficial to the miniaturized design of the pump structure.

[0047] The valve body 2 may be made of metal, plastic, silicone, etc. Those skilled in the art may determine the material according to actual conditions, and no specific limitation is made here.

[0048] In this example, the pump structure of the present application can be used in a cooling circulation system of an electronic device. Since the pump structure of the present application is compact, the cooling circulation system can be made more compact and have a better heat dissipation effect.

[0049] In an example, Figures 1 to 5 As shown, there are two movable pieces 22 , which are connected to the valve piece body 2 and are respectively located at two opposite sides of the first through hole 21 .

[0050] like Figure 5 As shown, the first through hole 21 on the valve plate body 2 is a square structure. Two movable plates 22 are provided, and the two movable plates 22 are respectively connected to the two opposite side walls of the first through hole 21. The two movable plates 22 can be embedded in the first through hole 21, so as to cooperate with each other to close the first through hole 21. One end of the two movable plates 22 can be movable to move out of the first through hole 21, for example, the movable plates 22 are pushed to deform under the action of hydraulic pressure, so as to open the first through hole 21.

[0051] In this example, the movable sheet 22 can be integrally formed with the valve sheet body 2. Figure 5 As shown, a “I”-shaped cutout can be cut out on the valve plate body 2 by cutting, thereby forming the first connecting hole and the two movable plates 22. Alternatively, the movable plate 22 can also be connected to the valve plate body 2 by bonding. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0052] In this example, the first through hole 21 may also be in other shapes, for example, the first through hole 21 may be a triangular hole, and three movable pieces 22 may be provided correspondingly. Alternatively, the first through hole 21 may also be a circular hole, and the movable piece 22 may be a sector-shaped piece, and a plurality of sector-shaped movable pieces 22 may be provided along the circumference of the first through hole 21.

[0053] Of course, the shape of the first through hole 21 and the number and shape of the movable pieces 22 can be determined by those skilled in the art according to actual conditions, and are not specifically limited here.

[0054] In an example, Figures 1 to 4 As shown, the shell 1 includes a first substrate 15, the first substrate 15 is provided with a first liquid outlet 151, the first liquid outlet 151 is connected to the pump chamber 11, and the side of the first substrate 15 facing away from the pump chamber 11 is connected to the valve plate body 2, and the valve plate body 2 is suitable for opening or closing the first liquid outlet 151.

[0055] like Figures 1 to 4 As shown, the first substrate 15 is provided with a first liquid outlet hole 151, and the first liquid outlet hole 151 can be connected to the pump chamber 11, and the valve plate body 2 is connected to the end of the first substrate 15 away from the pump chamber 11. The first through hole 21 corresponds to the first liquid outlet hole 151. The movable plate 22 can open or close the first through hole 21, that is, the movable plate 22 can open or close the first liquid outlet hole 151.

[0056] like Figure 3 As shown, when the pump structure discharges liquid, the hydraulic pressure in the pump chamber 11 increases, which can squeeze the movable sheet 22 to deform and open the first liquid outlet hole 151.

[0057] In an example, Figure 2 and Figure 3 As shown, the first substrate 15 is provided with a first limiting portion 153 , and the first limiting portion 153 is suitable for resisting an end of the movable sheet 22 facing the first substrate 15 .

[0058] like Figure 2 and Figure 3 As shown, the valve plate body 2 is located at one end of the first substrate 15 away from the pump chamber 11. The first substrate 15 is provided with a first limiting portion 153. When the pump structure is filled with liquid, the pressure in the pump chamber 11 is reduced, and the movable plate 22 can be supported by the first limiting portion 153, so that the movable plate 22 can stably close the first liquid outlet 151 to prevent liquid reflux.

[0059] like Figure 2 and Figure 4 As shown, two movable sheets 22 are provided, and the first substrate 15 is provided with two first liquid outlet holes 151, and a first limit portion 153 is provided between the two first liquid outlet holes 151. When liquid is introduced, one end of the two movable sheets 22 can be supported against the first limit portion 153, so that the two movable sheets 22 can close the two first liquid outlet holes 151. When liquid is discharged, the liquid pushes the two movable sheets 22 to deform, so as to open the two first liquid outlet holes 151 respectively.

[0060] The valve plate body 2 may be fixedly connected to the first substrate 15 by bonding, or by crimping, etc. Those skilled in the art may determine the method according to actual conditions, and no specific limitation is made here.

[0061] In an example, Figures 2 to 4 As shown, the housing 1 further includes a first cavity plate 14 , the first cavity plate 14 is provided with a second through hole 141 , one end of the first cavity plate 14 is connected to the first substrate 15 , and the second through hole 141 and the first substrate 15 form the pump cavity 11 .

[0062] like Figure 4 As shown, the first cavity plate 14 is penetrated by a second through hole 141, and the first cavity plate 14 is connected to the first substrate 15, so that the second through hole 141 and the first substrate 15 form the pump cavity 11. The first liquid outlet hole 151 corresponds to the second through hole 141, so that the first liquid outlet hole 151 is connected to the pump cavity 11.

[0063] In an example, Figures 2 to 4 As shown, the first substrate 15 is further provided with a first liquid inlet hole 152 , and the first liquid inlet hole 152 is connected to the pump chamber 11 .

[0064] like Figure 4 As shown, the first substrate 15 is also provided with a first liquid inlet hole 152, which corresponds to the position of the second through hole 141, so that the first liquid inlet hole 152 is connected to the pump cavity 11. When the pump structure is filled with liquid, the liquid can enter the pump cavity 11 from the first liquid inlet hole 152.

[0065] In this example, if Figure 4 As shown, the second through hole 141 of the first cavity plate 14 may be an elliptical hole. Alternatively, the second through hole 141 may also be a circular hole or a square hole, etc. Those skilled in the art may determine according to actual conditions, and no specific limitation is made here.

[0066] In this example, the first substrate 15 and the first cavity plate 14 can be fixedly connected by gluing or welding. Those skilled in the art can determine the method according to actual conditions, and no specific limitation is made here.

[0067] In an example, Figures 1 to 4 As shown, the shell 1 also includes a second substrate 17, the second substrate 17 is provided with a second liquid inlet hole 172, the second liquid inlet hole 172 is connected to the pump chamber 11, and the end of the second substrate 17 facing the pump chamber 11 is also connected to the valve plate body 2, and the valve plate body 2 is suitable for opening or closing the second liquid inlet hole 172.

[0068] like Figure 2As shown, the second substrate 17 is provided with a second liquid inlet hole 172, and the second liquid inlet hole 172 is connected to the pump chamber 11. The end of the second substrate 17 facing the pump chamber 11 is connected to the valve plate body 2, and the valve plate body 2 is suitable for opening or closing the second liquid inlet hole 172. The first through hole 21 corresponds to the second liquid outlet hole 171. The movable plate 22 can open or close the first through hole 21, that is, the movable plate 22 can open or close the second liquid outlet hole 171.

[0069] When the pump structure of the present application is filled with liquid, the hydraulic pressure in the pump chamber 11 increases, which can squeeze the movable sheet 22 to deform and open the second liquid outlet 171 .

[0070] In an example, Figure 2 and Figure 3 As shown, the second substrate 17 is provided with a second limiting portion 173 , and the second limiting portion 173 is suitable for resisting one end of the movable sheet 22 facing the second substrate 17 .

[0071] like Figure 2 and Figure 3 As shown, the valve plate body 2 is located at one end of the second substrate 17 facing the pump chamber 11. The second substrate 17 is provided with a second limiting portion 173. When the pump structure discharges liquid, the pressure in the pump chamber 11 increases, and the movable plate 22 can be supported by the second limiting portion 173, so that the movable plate 22 can stably close the second liquid outlet 171 to prevent the liquid from flowing into the liquid inlet channel 12.

[0072] like Figure 2 and Figure 4 As shown, two movable sheets 22 are provided, and the second substrate 17 is provided with two second liquid outlet holes 171, and a second limit portion 173 is provided between the two second liquid outlet holes 171. When liquid is discharged, one end of the two movable sheets 22 can be abutted against the second limit portion 173, so that the two movable sheets 22 can close the two second liquid outlet holes 171. When liquid is introduced, the liquid pushes the two movable sheets 22 to deform, so as to open the two second liquid outlet holes 171 respectively.

[0073] The valve plate body 2 may be fixedly connected to the second substrate 17 by bonding, or by crimping, etc. Those skilled in the art may determine the method according to actual conditions, and no specific limitation is made here.

[0074] For example, Figure 4 As shown, the second substrate 17 is provided with a mounting groove 174 , the valve plate body 2 is installed in the mounting groove 174 , and the bottom wall of the mounting groove 174 is provided with the second liquid inlet hole 172 .

[0075] The second substrate 17 has a mounting groove 174 at one end facing the pump chamber 11, and the valve body 2 is fixedly disposed in the mounting groove 174. The structure and shape of the mounting groove 174 match the valve body 2, so that the valve body 2 can be stably disposed in the mounting groove 174. Two second liquid inlet holes 172 are disposed on the bottom wall of the mounting groove 174, and a second stopper 173 is disposed between the two second liquid inlet holes 172.

[0076] In an example, Figures 2 to 4 As shown, the second substrate 17 is further provided with a second liquid outlet hole 171 , and the second liquid outlet hole 171 is connected to the first liquid outlet hole 151 to be connected to the pump chamber 11 .

[0077] In an example, Figures 1 to 4 As shown, the housing 1 further comprises a second cavity plate 16 , opposite ends of which are respectively connected to the first substrate 15 and the second substrate 17 , and the second cavity plate 16 can respectively press the two valve plate bodies 2 .

[0078] The first substrate 15 and the second substrate 17 are respectively located at opposite ends of the second cavity plate 16. The second cavity plate 16 can press the valve body 2 at the liquid outlet channel 13 to the first substrate 15 and press the valve body 2 at the liquid inlet channel 12 to the second substrate 17.

[0079] like Figure 2 and Figure 3 As shown, the second cavity plate 16 is provided with a third liquid outlet hole 161 and a third liquid inlet hole 162 , and the third liquid outlet hole 161 and the third liquid inlet hole 162 are respectively arranged opposite to the movable plates 22 of the two valve plate bodies 2 .

[0080] like Figure 2 As shown, the third liquid inlet hole 162 corresponds to the position of the valve plate body 2 at the liquid inlet channel 12. When liquid is inlet, the movable plate 22 is deformed and can extend into the third liquid inlet hole 162, and the third liquid inlet hole 162 can play a role in avoiding the movable plate 22. The two ends of the third liquid inlet hole 162 can be connected to the first liquid inlet hole 152 and the second liquid inlet hole 172 respectively to form the liquid inlet channel 12.

[0081] like Figure 3 As shown, the third liquid outlet hole 161 corresponds to the position of the valve plate body 2 at the liquid outlet channel 13. When the liquid is discharged, the movable plate 22 is deformed and can extend into the third liquid outlet hole 161, and the third liquid outlet hole 161 can play a role in avoiding the movable plate 22. The two ends of the third liquid outlet hole 161 can be connected to the first liquid outlet hole 151 and the second liquid outlet hole 171 respectively to form the liquid outlet channel 13.

[0082] The first substrate 15 and the second substrate 17 may be connected to the second cavity plate 16 by bonding to improve the sealing performance. Alternatively, they may be connected by other methods, which may be determined by those skilled in the art according to actual conditions and are not specifically limited here.

[0083] In an example, Figures 2 to 4 As shown, the pump structure further includes a bottom plate 18. The bottom plate 18 is connected to an end of the second substrate 17 away from the second cavity plate 16. For example, the bottom plate 18 can also be connected to the second substrate 17 by bonding.

[0084] The bottom plate 18 is provided with a fourth liquid inlet hole 181 and a fourth liquid outlet hole 182. The fourth liquid inlet hole 181 is connected to the second liquid inlet hole 172, and external liquid can flow into the second liquid inlet hole 172 through the fourth liquid inlet hole 181, and then flow into the liquid inlet channel 12. The fourth liquid outlet hole 182 is connected to the second liquid outlet hole 171, so that the liquid outlet channel 13 is connected to the fourth liquid outlet hole 182, and the liquid in the pump chamber 11 can flow out from the fourth liquid outlet hole 182.

[0085] In an example, Figures 1 to 4 As shown, the pump structure further includes a piezoelectric component 3 , which is connected to one end of the first cavity plate 14 facing away from the first substrate 15 , and the piezoelectric component 3 is capable of sealing the second through hole 141 .

[0086] like Figure 2 and Figure 3 As shown, the pump structure may be a piezoelectric pump. The piezoelectric component 3 is sealed and disposed at the open end of the pump chamber 11. The piezoelectric component 3 is deformed to change the pressure in the pump chamber 11 to achieve liquid inlet and outlet.

[0087] For example, Figure 1 and Figure 2 As shown, when the piezoelectric pump is filled with liquid, the piezoelectric component 3 deforms in the direction away from the open end of the pump chamber 11, that is, deforms upward, the volume of the pump chamber 11 increases, and the pressure decreases. Under the action of pressure, the liquid in the liquid inlet channel 12 causes the movable plate 22 of the valve plate body 2 at the liquid inlet channel 12 to deform upward to open the liquid inlet channel 12, and the liquid flows into the pump chamber 11. At the same time, under the action of pressure, the movable plate 22 of the valve plate body 2 of the liquid outlet channel 13 is pressed against the first limiting portion 153, thereby closing the liquid outlet channel 13 to prevent the liquid in the liquid outlet channel 13 from flowing back.

[0088] like Figure 1 and Figure 3As shown, when the piezoelectric pump discharges liquid, the piezoelectric component 3 deforms toward the open end of the pump chamber 11, that is, deforms downward, the volume of the pump chamber 11 decreases, and the pressure increases. Under the action of pressure, the liquid in the liquid outlet channel 13 causes the movable plate 22 of the valve plate body 2 at the liquid outlet channel 13 to deform downward to open the liquid outlet channel 13, and the liquid flows out of the pump chamber 11. At the same time, under the action of pressure, the movable plate 22 of the valve plate body 2 of the liquid inlet channel 12 is pressed against the second limiting portion 173, thereby closing the liquid inlet channel 12 to prevent the liquid from flowing out of the liquid inlet channel 12. This reciprocating cycle ensures that the fluid in the circulating waterway can circulate in a directional manner.

[0089] In this example, if Figure 4 As shown, the piezoelectric assembly 3 includes a piezoelectric element 31, a vibration plate 32 and a vibration membrane 33. The vibration plate 32 is bonded to the end of the first cavity plate 14 away from the first substrate 15, and the vibration membrane 33 is used to seal the open end of the pump cavity 11. The vibration plate 32 is connected to the end of the vibration membrane 33 away from the first cavity plate 14. The piezoelectric element 31 is bonded to the end of the vibration plate 32 away from the vibration membrane 33. When the piezoelectric element 31 is energized, the piezoelectric element 31 can be deformed, thereby driving the vibration plate 32 and the vibration membrane 33 to deform, so as to change the volume of the pump cavity 11.

[0090] The vibration plate 32 may be made of metal materials such as gold, platinum, copper, silver, tungsten, aluminum or other alloys. The vibration membrane 33 may be made of materials such as polycarbonate (PC), polyethylene terephthalate (PET), silica gel, polyethylene (PE) or polypropylene (PP). Of course, the materials of the vibration plate 32 and the vibration membrane 33 can be determined by those skilled in the art according to actual conditions, and are not specifically limited here.

[0093] The valve plate body 2 is arranged in the liquid inlet channel 12 and / or the liquid outlet channel 13 of the pump chamber 11, and the valve plate body 2 has a first through hole 21. The valve plate body 2 is also provided with a plurality of movable plates 22, and the plurality of movable plates 22 are suitable for closing or opening the first through hole 21. By providing a plurality of movable plates 22, the liquid output of the liquid inlet channel 12 and / or the liquid outlet channel 13 can be increased within a limited space, so that the structure of the pump structure is more compact, which is conducive to the miniaturized design of the pump structure, and thus is conducive to the miniaturized design of the electronic device.
