[0002] The jet pump is a liquid transmission device. Different from the traditional peristaltic pump and negative displacement pump, the working principle of the jet pump is to use the impact of high-speed fluid to push the liquid into the pipeline for transmission.

[0003] The water pump coil is an important component that converts electrical energy into mechanical energy. Its working principle is based on the theory of electromagnetic induction. When electricity is passed through the wire in the water pump coil, a magnetic field will be generated around it. This magnetic field will generate an electromotive force on the conductor around the water pump coil. According to the principle of electromagnetic induction, when a conductor moves in a magnetic field, an electromotive force will be generated, which can be used to drive the water pump.

[0004] However, in the prior art, when the coil needs to be disassembled for repair or recycling of the jet pump, there is a lack of suitable disassembly equipment to assist, which makes the operation of disassembling the internal coil of the jet pump complicated and laborious, and the disassembly of the internal coil of the jet pump cannot be completed quickly.

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

[0024] A jet pump coil disassembly device comprises a jet pump housing 1 and a coil 2 arranged inside the jet pump housing 1, a disassembly mechanism is arranged on the inner side of the coil 2, the disassembly mechanism comprises an elastic tooling outer ring 3 and a tooling inner ring 4, the tooling inner ring 4 is arranged at one end inside the tooling outer ring 3, the tooling inner ring 4 is designed as a platform, and a protruding component 5 is fixedly connected to the outer surface of the tooling outer ring 3.

[0025] There is a threaded groove at the center of the tooling inner ring 4, and a screw rod 6 is threadedly connected to the center of the tooling inner ring 4. An upper cover 7 is provided at the end of the tooling outer ring 3 away from the tooling inner ring 4. One end of the screw rod 6 penetrates the upper cover 7 and extends to the outside of the upper cover 7. The end of the screw rod 6 located outside the upper cover 7 is fixedly connected to a cross pin 8.

[0026] like Figure 3 and Figure 4 The inner ring 4 of the tooling is located at one end of the outer ring 3 of the tooling close to the inside of the jet pump housing 1. The inner ring 4 of the tooling is a table, and its radius decreases gradually toward the inside of the outer ring 3 of the tooling. There is an opening inside the outer ring 3 of the tooling, so that the inner ring 4 of the tooling can move toward the inside of the outer ring 3 of the tooling. The cross pin 8 is directly fixed to the screw rod 6, so that when the cross pin 8 is rotated, the screw rod 6 can be driven to rotate.

[0027] The coil 2 is sleeved on the outside of the tooling outer ring 3, and the outer surface of the tooling outer ring 3 is provided with an annular concave. The outer surface of the tooling outer ring 3 and the inner part of the annular concave are sleeved with a rubber band 9.

[0028] like Figure 3 and Figure 4 The rubber band 9 is sleeved on the outside of the tooling outer ring 3 to tighten the tooling outer ring 3 so that the tooling outer ring 3 can be more easily inserted into the injection pump housing 1 and the coil 2.

[0029] An annular groove 10 is formed on one side of the tooling outer ring 3 , and an annular clamping piece 11 used in conjunction with the annular groove 10 is fixedly connected to one side of the upper cover 7 .

[0030] like Figure 3 The annular clamping piece 11 can be just inserted into the annular groove 10 to clamp the upper cover 7 on one end of the tooling outer ring 3.

[0031] One end of the screw rod 6 is fixedly connected with an annular extrusion piece 12 , and the annular extrusion piece 12 is used to extrude the tooling inner ring 4 into the tooling outer ring 3 .

[0032] like Figure 3 and Figure 4 The radius of the annular extrusion 12 is greater than the radius of the opening of the tooling inner ring 4 , so that the annular extrusion 12 cannot pass through the tooling inner ring 4 .

[0033] A fixing frame 13 is provided at one end of the housing 1, a fixing plate 14 is fixedly connected to one side of the fixing frame 13, a threaded pipe 15 is fixedly connected to one end of the fixing plate 14 and is located inside the jet pump housing 1, and fixing holes 16 are opened on the fixing frame 13 and on both sides of the fixing plate 14.

[0034] like Figure 2 One end of the jet pump housing 1 is a cavity, so that when the limit ring 17 is sleeved on the jet pump housing 1, the threaded tube 15 can be located in the cavity at one end of the jet pump housing 1, and the fixing frame 13 can be fixed with the assistance of the fixing hole 16 and an external mechanism.

[0035] A limiting ring 17 is sleeved on the jet pump housing 1, and both ends of the fixing frame 13 are fixedly connected to the limiting ring 17. An arc portion 171 is provided on the limiting ring 17, and a handle 18 is provided on the top of the arc portion 171. A fixing screw 19 is fixedly connected to the bottom of the handle 18, and one end of the fixing screw 19 passes through the arc portion 171 and the jet pump housing 1 in sequence, and is threadedly connected to the threaded pipe 15.

[0036] like Figure 1 and Figure 2 The fixing screw 19 passes through the hole on the jet pump housing 1, and is sleeved on the surface of the jet pump housing 1 through the limiting ring 17. The fixing screw 19 then passes through the jet pump housing 1 and is threadedly connected to the threaded tube 15. The jet pump housing 1 can be positioned so that the jet pump housing 1 will not move when the coil 2 is disassembled.

[0037] The working principle of the jet pump coil disassembly device provided by the utility model is as follows:

[0038] When the coil 2 inside the jet pump housing 1 needs to be disassembled, one end of the tooling inner ring 4 can be pushed into the jet pump housing 1 so that the tooling outer ring 3 passes through the coil 2. At this time, the screw rod 6 can be squeezed to rotate counterclockwise, and the screw rod 6 drives the annular extrusion piece 12 to move upward. The annular extrusion piece 12 pushes the tooling inner ring 4. When the tooling inner ring 4 moves, it squeezes the inner wall of the tooling outer ring 3, so that the tooling outer ring 3 expands outward. At this time, the protruding part 5 can be made to contact one end of the coil 2;

[0039] At this time, the cross pin 8 can be pulled away from the jet pump housing 1 to drive the screw rod 6 and the annular extrusion 12 to move, the annular extrusion 12 pushes the tooling inner ring 4, the tooling inner ring 4 pushes the tooling outer ring 3, the tooling outer ring 3 pushes the coil 2 through the raised part 5, and the coil 2 is pushed out from the inside of the jet pump housing 1, completing the disassembly of the coil 2;

[0040] Then the screw rod 6 can be rotated to separate the annular extrusion piece 12 and the tooling inner ring 4. At this time, under the tightening effect of the rubber band 9, the tooling outer ring 3 is reset, and the raised part 5 no longer contacts the coil 2, so the coil 2 can be removed from the tooling outer ring 3.

[0041] Compared with the related art, the jet pump coil disassembly device provided by the utility model has the following advantages:

[0042] Beneficial effects:

[0043] The utility model extends the tooling inner ring 4 and the tooling outer ring 3 into the interior of the jet pump housing 1, and rotates the screw rod 6 to make the protruding component 5 abut against one end of the coil 2. At this time, the coil 2 is quickly pulled out from the interior of the jet pump housing 1 by pulling the screw rod 6, and the disassembly of the coil 2 is completed. The operation is simple and easy to use, making it more convenient and labor-saving to disassemble the coil 2 inside the jet pump housing 1, thereby improving the disassembly speed of the coil 2.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
