Description

Technical Field

[0001] The invention belongs to the technical field of commutators, and in particular relates to an electromagnetic commutator. Background Art

[0002] As an important basic equipment that is indispensable in industry, transportation, national defense and daily life, the commutator's downstream industries include almost all basic industries of the national economy. Its application fields are very wide. For example, in the field of liquid flow commutation, the fluid commutation can be achieved through an electromagnetic commutator.

[0003] At present, most of the liquid flow standard devices are fixed and have a large flow rate. The commutators used for fluid reversing in large-flow fixed liquid flow standard devices are mostly pneumatic commutators. Pneumatic commutators are generally large in size and complex in structure. They are mostly composed of air compressors, air tanks and many pipelines to form a pneumatic system. They have high requirements for space and cannot be moved at will, and are not suitable for the circular direction and detection needs of small flows. At present, electromagnetic commutators already exist as commutators for reversing small-flow liquids, but the shells of existing electromagnetic commutators are mostly closed, which is not convenient for repairing and replacing parts inside the shell. In addition, when in use, for example, when water or oil is inlet, impurities are easily accumulated inside the commutator, which is not easy to clean. As the use time increases, the commutator may even be damaged. At this time, the entire commutator can only be replaced, and the maintenance cost is high. Summary of the invention

[0004] An object of the present invention is to provide an electromagnetic commutator for solving at least one problem existing in the prior art.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The present invention provides an electromagnetic commutator, comprising a commutator housing, wherein the commutator housing is provided with a liquid inlet and a plurality of switching ports, and a fluid channel is formed between the liquid inlet and each of the switching ports;

[0007] A valve core is provided inside the commutator housing, and the valve core includes multiple sliders. One side of each slider is slidably connected to the inner wall of the commutator housing, and the other side of each slider is connected to a pull rod. The pull rod is sleeved on the electromagnet, and one side of the electromagnet is connected to the valve core. When the electromagnet is energized, the pull rod is driven to drive the slider to move, so that the slider blocks one or more switching ports.

[0008] In one possible design, the switching port includes a first switching port, a second switching port, a third switching port and a fourth switching port, wherein the first switching port and the second switching port are opened on the same side of the commutator housing, and the third switching port and the fourth switching port are opened on the other side of the commutator housing.

[0009] In a possible design, the slider includes a first slider and a second slider, the first slider is slidably arranged on the same side as the first switching port and the second switching port, and the second slider is slidably arranged on the same side as the third switching port and the fourth switching port.

[0010] In a possible design, when the electromagnet loses power, the first slider slides to the bottom of the first switching port to block the first switching port, and the second switching port, the third switching port and the fourth switching port are connected.

[0011] In one possible design, when the electromagnet is energized, the pull rod drives the first slider and the second slider to move, the second slider slides to just above the fourth switching port, blocking the fourth switching port, and the first switching port, the second switching port and the third switching port are connected.

[0012] In a possible design, a return spring is provided in the electromagnet.

Obviously, the described embodiments are part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example

[0022] like Figure 1-2 As shown, the present invention provides an electromagnetic commutator, comprising a commutator housing 1, wherein the commutator housing 1 is provided with a liquid inlet 7 and a plurality of switching ports, wherein a fluid channel is formed between the liquid inlet 7 and each of the switching ports, and preferably, the liquid inlet 7 is a water inlet or an oil inlet, so that when water or oil enters the electromagnetic commutator, different switching ports are connected so that the fluid is discharged from different switching ports to achieve commutation;

[0023] A valve core 2 is provided inside the commutator housing 1, and the valve core 2 includes a plurality of sliders, one side of the plurality of sliders is slidably connected to the inner wall of the commutator housing 1, and the other side of the plurality of sliders is connected to a pull rod 4, and the pull rod 4 is sleeved on an electromagnet 5, one side of the electromagnet 5 is connected to the valve core 2, and when the electromagnet 5 is energized, the pull rod 4 is driven to drive the slider to move, so that the slider blocks one or more switching ports, thereby realizing the switching conduction of the fluid channel.

[0024] Based on the above disclosed content, this embodiment can realize the switching conduction of the fluid channel, so that the reversal of the fluid can be realized very conveniently. In addition, since the valve core 2 is slidably connected to the housing in the form of a slider, it is easy to disassemble, and then easy to clean and repair.

[0025] As an optional implementation of this embodiment, the switching port includes a first switching port 61, a second switching port 62, a third switching port 63 and a fourth switching port 64, wherein the first switching port 61 and the second switching port 62 are opened on the same side of the commutator housing 1, and the third switching port 63 and the fourth switching port 64 are opened on the other side of the commutator housing 1. The liquid inlet 7 is opened on another side of the commutator housing 1.

[0026] Specifically, for ease of understanding, such as Figure 1 As shown, the liquid inlet 7, the first switching port 61, the second switching port 62, the third switching port 63 and the fourth switching port 64 are briefly described as follows: the liquid inlet 7 is port 1, the first switching port 61 is port 2, the second switching port 62 is port 3, the third switching port 63 is port 4, and the fourth switching port 64 is port 5. Of course, it can be understood that this embodiment is not only applicable to electromagnetic commutators with only 4 switching ports, but also to electromagnetic commutators with other numbers of switching ports, which can be set according to actual business scenarios and are not limited here.

[0027] As an optional implementation of this embodiment, the slider includes a first slider 31 and a second slider 32, the first slider 31 is slidably set on the same side of the first switching port 61 and the second switching port 62, and the second slider 32 is slidably set on the same side of the third switching port 63 and the fourth switching port 64.

[0028] Of course, it can be understood that this embodiment is not only applicable to the electromagnetic commutator in which the valve core 2 is provided with a first slider 31 and a second slider 32. Specifically, the number of sliders can be adjusted according to the setting of the switching port to adapt to different business scenarios, and no limitation is made here.

[0029] As an optional implementation of this embodiment, when the electromagnet 5 loses power, the first slider 31 is slidably disposed directly below the first switching port 61 to block the first switching port 61, and the second switching port 62, the third switching port 63 and the fourth switching port 64 are connected, that is, Figure 2 The No. 2 port in the figure is blocked, and the second switching port 62, the third switching port 63 and the fourth switching port 64 are connected. When the electromagnet 5 is energized, the internal coil of the electromagnet 5 is energized, and the iron core of the electromagnet 5 generates magnetic force. Under the action of the magnetic force, the pull rod 4 moves to the right in the figure, driving the first slider 31 and the second slider 32 to move. The second slider 32 stops and is set just above the fourth switching port 64, blocking the fourth switching port 64. The first switching port 61, the second switching port 62 and the third switching port 63 are connected, that is, Figure 1 Port No. 5 is blocked, and the first switch port 61, the second switch port 62 and the third switch port 63 are connected.

[0030] As an optional implementation of the present embodiment, a reset spring is provided in the electromagnet 5. When the electromagnet 5 is energized and drives the pull rod 4 to complete the switching of the switching port, the pull rod 4 is restored to the position when the power is lost through the reset spring in the electromagnet 5, and the cycle is repeated to achieve the switching of different switching ports.

[0031] As an optional implementation of this embodiment, the commutator housing 1 is made of stainless steel. Of course, it can be understood that only one of the selected materials for the electromagnetic commutator housing 1 of this embodiment is shown here, and it can also be made of materials such as plastic and brass as needed, which is not limited here.

[0032] It should be noted that the specific working principle of the electromagnetic commutator in this embodiment is as follows:

[0033] When the electromagnet 5 loses power, the pull rod 4 does not move. At this time, the first slider 31 is slidably arranged just below the first switching port 61 to block the first switching port 61, and the second switching port 62, the third switching port 63 and the fourth switching port 64 are connected. Figure 2 The No. 2 port in the figure is blocked, and the second switching port 62, the third switching port 63 and the fourth switching port 64 are connected. When the electromagnet 5 is energized, the internal coil of the electromagnet 5 is energized, and the iron core of the electromagnet 5 generates magnetic force. Under the action of the magnetic force, the pull rod 4 moves to the right in the figure, driving the first slider 31 and the second slider 32 to move. The second slider 32 stops and is set just above the fourth switching port 64, blocking the fourth switching port 64, and the first switching port 61, the second switching port 62 and the third switching port 63 are connected, that is, Figure 1 Port No. 5 is blocked, and the first switch port 61, the second switch port 62 and the third switch port 63 are connected.

[0034] Beneficial effects:

When the electromagnet 5 is energized, the pull rod 4 is driven to drive the slider to move, so that the slider blocks one or more of the switching ports, and the switching conduction of the fluid channel is realized, so that the reversal of the fluid can be realized very conveniently. In addition, since the valve core 2 is slidably connected to the housing in the form of a slider, it is easy to disassemble, and thus easy to clean and repair.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
