Embodiments of the present application will be described below with reference to the drawings.
Embodiments of the first aspect
Embodiments of a first aspect of the present application provide a pump. FIG. 1 is a schematic view of a pump according to an embodiment of the present application, with various components of the pump of FIG. 1 broken away.
As shown in fig. 1, the pump 100 includes:
a motor 101 having a rotation shaft 1011 rotating around a central axis OO';
a coupling member 102 disposed on one axial side (i.e., on the O side of the axis OO') of the motor 101;
a diaphragm 103 moved by the motor 101 through the connection member 102;
a diaphragm holder 104 that supports the diaphragm 103;
a valve holder 105 disposed on one axial side (i.e., on the O side of the axis OO') of the diaphragm holder 104 and fixed to the diaphragm holder 104;
an intake valve 106 disposed on the other axial side (i.e., on the O 'side of the axis OO') of the valve holder 105 and fixed to the valve holder 105;
an exhaust valve 107 disposed on one axial side (i.e., on the O side of the axis OO') of the valve holder 105 and fixed to the valve holder 105; and
a cover 108 disposed on one axial side (i.e., on the O side of the axis OO') of the valve holder 105.
In the embodiment of the present application, when the motor 101 rotates, the rotating shaft 1011 rotates around the central axis OO', and drives the connecting member 102 to perform stretching and compressing motions in the axial direction, and further drives the diaphragm 103 to perform reciprocating motions in the axial direction. The diaphragm support 104 may be fixed to the casing of the motor 101, or may be integrally formed with the casing, which is not limited in this application; further, with respect to the specific structure of the pump, reference is also made to the related art.
When the diaphragm 103 moves to one axial side (O side), air in the chamber is compressed, the intake valve 106 is stopped by the chamber air pressure, the exhaust valve 107 is opened by the chamber air pressure, and the air in the chamber is discharged to the outside through the exhaust valve 107. When the diaphragm 103 moves to the other axial side (O' side), air in the chamber is diluted, the exhaust valve 107 is stopped by the external air pressure, the intake valve 106 is opened by the external air pressure, and external air is sucked into the chamber through the intake valve 106.
It should be noted that fig. 1 illustrates the pump of the present application only by way of a small or ultra-small pump with two suction valves 106 and two suction chambers, but the present application is not limited thereto; for example, it is also applicable to other types of pumps, and other components or devices may be provided, and reference may be made to the related art, and the description thereof will be omitted. Reference may be made to the related art for components or elements (e.g., housing, sealing members, mounting screws, etc.) not specifically identified in fig. 1, which is not intended to be limiting.
FIG. 2 is a schematic view of an exhaust valve 107 according to an embodiment of the present application, showing the exhaust valve 107 as viewed from the side; fig. 3 is a schematic view of the valve holder 105 and the exhaust valve 107 according to the embodiment of the present application, showing the exhaust valve 107 after being mounted on the valve holder 105 as viewed from above (i.e., as viewed from the O side to the O' side).
As shown in fig. 2 and 3, the exhaust valve 107 has a non-circular closing portion 201 and an extension portion 202 extending axially from the closing portion 201, and the exhaust valve 107 is fixed to the valve holder 105 by the extension portion 202. For example, the extension 202 may be provided with a protrusion 2021 to fix the exhaust valve 107.
Thus, the non-circular closing portion 201 of one exhaust valve 107 can cover at least two exhaust holes, which can reduce the number of exhaust valves and reduce noise; furthermore, the movement of the non-circular closing part 201 is limited in the circumference, so that the positioning of the vent valve 107 can be ensured; further, the non-circular closing portion 201 does not contact the wall portion of the valve holder 105, and malfunction due to friction can be avoided.
In some embodiments, as shown in fig. 2 and 3, the closure 201 is plate-shaped and oval in shape. Thus, by providing the edge of the closing portion 201 of the exhaust valve 107 in a smooth elliptical shape, resistance due to friction can be further prevented. However, the present application is not limited thereto, and the shape of the closing portion 201 of the discharge valve 107 will be further described below.
Fig. 4 is an exemplary view of another exhaust valve 107 according to the embodiment of the present application, showing the exhaust valve 107 when viewed from the front. As shown in fig. 4, the closing portion 201 of the exhaust valve 107 according to the embodiment of the present application is not limited to an oval shape, and may have a shape with two notches, for example.
In some embodiments, as shown in fig. 4, the enclosure 201 has two ends 401; each end 401 has rounded edges and each end 401 covers a vent hole in the valve carriage 105. As shown in fig. 4, the width W1 of the closing part 201 in the first direction, which is a direction connecting the two end parts 401, is larger than the width W2 in the second direction, which is perpendicular to the first direction.
As shown in fig. 4, a connecting portion 402 is provided between the two end portions 401, and a maximum width W3 of the connecting portion 402 in the second direction is smaller than or equal to a maximum width W4 of the end portion 401 in the second direction (W4 ═ W2 in fig. 4).
Note that fig. 4 schematically illustrates only the shape of the closing portion 201, but the present application is not limited thereto, and for example, the closing portion 201 may have a shape with only one notch portion, or another shape. Fig. 5 is an exemplary view of another exhaust valve 107 according to the embodiment of the present application, and fig. 6 is an exemplary view of another exhaust valve 107 according to the embodiment of the present application, each showing the exhaust valve 107 viewed from the front, but the present application is not limited thereto.
Thus, the exhaust valve with the structure can further reduce friction and avoid bad actions.
In some embodiments, vent valve 107 is a resilient member integrally formed with closure portion 201 and extension portion 202. For example, the rubber product may be integrally molded, but the present application is not limited thereto, and for example, the rubber product may be integrally molded, such as a resin product or a metal product.
This reduces the number of parts, simplifies assembly, and further reduces cost.
The exhaust valve with two notches in fig. 4 will be described again as an example.
FIG. 7 is another schematic view of the valve holder 105 and exhaust valve 107 of an embodiment of the present application, showing the valve holder 105 and exhaust valve 107 viewed from the side; fig. 8 is another schematic view of the valve holder 105 and the exhaust valve 107 according to the embodiment of the present application, showing the valve holder 105 and the exhaust valve 107 as viewed from above (i.e., from the O side to the O' side).
As shown in fig. 7 and 8, the valve holder 105 is provided with an intake space 701 in which the intake valve 106 is disposed and an exhaust space 702 in which the exhaust valve 107 is disposed; the exhaust space 702 is provided with at least two exhaust holes 7021, and the suction space 701 is provided with at least two suction holes 7011. For example, the at least two suction holes 7011 may be divided into two groups, which are respectively located at both sides of the suction space 701.
In some embodiments, the number of the exhaust valves 107 is one, covering at least two exhaust holes 7021 of the exhaust space 702; the number of the suction valves 106 is two, and each suction valve 106 covers a group of suction holes 7011 of the suction space 701.
As shown in fig. 7 and 8, the exhaust space 702 includes a first groove portion 801 recessed in the axial direction from a first end surface 1051 of the valve holder 105, and a first wall portion 7022 is provided on the outer periphery of the first groove portion 801; the suction space 701 includes a second groove portion 802 axially recessed from the second end surface 1052 of the valve holder 105, and a second wall portion 7012 is provided on the outer periphery of the second groove portion 802.
As shown in fig. 7 and 8, the inner wall of the first wall portion 7022 is non-circular, and the outer wall of the first wall portion 7022 is quadrilateral; in a state where the exhaust valve 107 is fixed to the valve holder 105, the edge of the closing portion 201 of the exhaust valve 107 does not contact the inner wall of the first wall portion 7022.
Thus, the first wall portion 7022 can be fitted to the non-circular closing portion 201, and the exhaust operation can be performed even when the flow rate is small such as in a small pump or a micro pump, and the malfunction due to friction can be avoided. Further, the first wall portion 7022 is substantially quadrangular; because the shape of the quadrangle is more regular, the dislocation is not easy to occur when the components such as the sealing gasket are assembled, thereby being beneficial to the sealing of the rubber sealing gasket.
In some embodiments, the height of the first wall portion 7022 in the axial direction is lower than or equal to the height of the second wall portion 7012 in the axial direction; in the case where the exhaust valve 107 is fixed to the valve holder 105, the height of the exhaust valve 107 in the axial direction is lower than the height of the first wall portion 7022 in the axial direction.
FIG. 9 is another schematic view of the valve holder 105 and the exhaust valve 107 according to the embodiment of the present application, showing the valve holder 105 and the exhaust valve 107 viewed along line AA' of FIG. 8; fig. 10 is another schematic view of the valve holder 105 according to the embodiment of the present application, showing the valve holder 105 viewed from fig. 9 with the exhaust valve 107 removed.
As shown in fig. 9 and 10, the height of the first wall portion 7022 in the axial direction is lower than or equal to the height of the second wall portion 7012 in the axial direction (the same is exemplified in fig. 9 and 10). As shown in fig. 9, in the case where the exhaust valve 107 is fixed to the valve holder 105, the height of the exhaust valve 107 in the axial direction is lower than the height of the first wall portion 7022 in the axial direction.
This makes it possible to increase the intake space and the exhaust space as much as possible. For example, when the exhaust valve 107 is fixed to the valve holder 105, the exhaust space 702 still has a space for performing the exhaust operation.
In addition, the above is only an exemplary explanation of each device or component, but the present application is not limited thereto, and the specific contents of each device or component may also refer to the related art; it is also possible to add devices or components not shown in fig. 1 to 10 or to reduce one or more devices or components in fig. 1 to 10.
According to an embodiment of the application, the outlet valve has a non-circular closing portion and an extension portion extending axially from the closing portion, by means of which extension portion the outlet valve is fixed to the valve holder. Therefore, the number of exhaust valves can be reduced, and noise can be reduced; in addition, the non-circular closing portion can ensure positioning and avoid malfunction due to friction.
