Description

Technical Field

[0001] This utility model belongs to the field of pump equipment, and specifically relates to a magnetic pump. Background Technology

[0002] A magnetic pump is a type of pump that utilizes magnetic force to achieve leak-free, contactless rotary drive. The main characteristic of a magnetic pump is the absence of a mechanical connection between the drive shaft and the pump shaft; instead, torque is transmitted through a magnetic field, thus avoiding the leakage problems that can arise from traditional sealing methods. In applications such as whirlpools, the magnetic pump draws water from the inlet and sprays it from the outlet, achieving a massage effect on the skin. However, current magnetic pumps are structurally complex, require numerous magnets, and have inconvenient end cap and outlet installation. Therefore, to overcome the shortcomings of existing technology, improvements are necessary. Utility Model Content

[0003] The purpose of this invention is to provide a magnetic pump with a simple structure, reduced use of magnets, lower cost, and convenient installation of end caps and outlet.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A magnetic pump includes a pump body, a turntable, a flow guide, and an end cover. A rotor is housed inside the pump body, and a rotating shaft is connected to the rotor. A partition is provided on the pump body cover. The turntable is connected to the end of the rotating shaft near the partition. A plurality of magnets are spaced circumferentially along the center of the turntable and are fixedly mounted on it. The flow guide is located on the partition and contains blades that rotate under the influence of the magnets. The blades have folded edges for propelling water flow. A flow guide groove is provided along the inner edge of the flow guide, and the end of the flow guide groove has an upwardly curved arc-shaped flow guide surface. The end cover covers the flow guide and has a water inlet at its center, communicating with the interior of the flow guide. A spray nozzle is provided on the end cover, communicating with the interior of the flow guide and aligned with the end of the flow guide groove.

[0006] As a preferred embodiment of the aforementioned magnetic pump, there are four magnets, which are embedded and mounted on the turntable.

[0007] As a preferred embodiment of the aforementioned magnetic pump, the turntable is provided with an opening extending outward along the central circumference, the opening matching the shape of the magnet, and the four magnets are fixed in the opening by screws.

[0008] As a preferred embodiment of the aforementioned magnetic pump, the blades are made of iron sheets.

[0009] As a preferred embodiment of the aforementioned magnetic pump, there are two guide channels, which are arranged symmetrically around the center of the guide section. There are two spray nozzles, which are respectively located above the ends of the two guide channels.

[0010] As a preferred embodiment of the aforementioned magnetic pump, the width of the guide groove gradually increases from the initial end to the final end.

[0011] As a preferred embodiment of the aforementioned magnetic pump, the end cap is bent inward and recessed at the water inlet to form an arc-shaped surface.

[0012] As a preferred embodiment of the aforementioned magnetic pump, the flow guide is magnetically attached to the partition plate under the magnetic force of the magnet, and the partition plate is provided with a positioning hole, into which the flow guide is inserted.

[0013] The advantages of implementing the magnetic pump provided by this utility model compared with the prior art are as follows:

[0014] This invention draws water into the guide section from the inlet. The water in the guide section is propelled by rotating blades along the guide channel to its end, where it is sprayed out from the nozzle. When the rotor is energized, it rotates, causing the turntable to rotate, which in turn rotates the magnet fixedly mounted on the turntable. The turntable is located at the end of the rotating shaft near the partition. During the magnet's rotation, the blades rotate under the magnetic attraction of the magnetic force through the partition. When energized, the rotor drives the rotating shaft to rotate, which in turn drives the turntable, causing the magnet to rotate along with it. The magnet, through the partition, magnetically attracts the blades, causing them to rotate as well. The rotation of the blades creates a vortex-shaped negative pressure area in the center of the guide section, allowing... External water is drawn into the guide section through the inlet at the center of the end cap. The rotation of the blades pushes the water in the guide section to the guide groove at the edge of the guide section, and sprays it out from the end of the guide groove to the spray nozzle. The guide section and the turntable are separated by a baffle, so that water will not leak to the turntable side when water enters the guide section, protecting the rotor and shaft and preventing water ingress from causing leakage or malfunction. Several magnets are set at intervals along the center circumference of the turntable. The turntable does not need to be made into a magnet, but it can still magnetically attract the blades, saving magnets and reducing manufacturing costs. The turntable can stably drive the magnets to rotate, thereby driving the blades to rotate. The structure is simple, and the end cap is placed on the guide section. The end cap is easy to disassemble and assemble. Attached Figure Description

[0027] Please refer to the following: Figures 1 to 5 The magnetic pump provided in the embodiments of this utility model will now be described.

[0028] like Figures 1 to 5 As shown, the magnetic pump of this utility model includes a pump body 100, a turntable 130, a flow guide 200, and an end cover 300. A rotor 110 is disposed inside the pump body 100, and a rotating shaft 120 is connected to the rotor 110. A partition 140 is provided on the top cover of the pump body 100. The turntable 130 is connected to one end of the rotating shaft 120 near the partition 140. A plurality of magnets 131 are spaced circumferentially along the center of the turntable 130 and are fixedly mounted on the turntable 130. The flow guide 200 is disposed on the partition 140, and a flow guide 200 is provided within the flow guide 200 that can be directed to the magnets 131. Driven by 31, the blade 210 rotates. The blade 210 is provided with a folded edge 211 for propelling the water flow. The inner edge of the guide section 200 is provided with a guide groove 220. The end of the guide groove 220 is provided with an upwardly curved arc guide surface 221. The end cap 300 covers the guide section 200. The center of the end cap 300 is provided with a water inlet 310. The water inlet 310 communicates with the interior of the guide section 200. The end cap 300 is provided with a spray nozzle 320. The spray nozzle 320 communicates with the interior of the guide section 200 and is aligned with the end of the guide groove 220.

[0029] Specifically, the flow guide 200 has a raised positioning post at its center, and the blade 210 has a through hole at its center that can cooperate with the positioning post. The positioning post passes through the through hole, and the blade 210 rotates around the positioning post at the center of the flow guide 200. Since the blade 210 is provided with a folded edge 211 for pushing the water flow, when the blade 210 rotates, the folded edge 211 pushes the water to the edge of the flow guide 200. In this way, the water will be pushed to the flow guide 220 and pushed to the end of the flow guide 220, and then sprayed out at the nozzle 320.

[0030] For example, there are four magnets 131, which are embedded in the turntable 130. The four magnets 131 are embedded in the turntable 130. When the turntable 130 rotates, it can drive the four magnets 131 to rotate. The embedding ensures that there is no extra space for the magnets 131 to deviate when they are driven to rotate, thus ensuring that the blades 210 can be firmly magnetically attracted and driven to move.

[0031] For example, the turntable 130 is provided with an opening 132 extending outward along the center circumference. The opening 132 matches the shape of the magnet 131. The four magnets 131 are fixed in the opening 132 by screws. The matching shape of the opening 132 and the magnet 131 ensures that the magnets 131 do not have extra space to cause displacement when the turntable rotates. The opening 132 extending outward along the center circumference makes the turntable lighter and the rotation effect better.

[0032] For example, the blade 210 is made of iron sheet. Making the blade 210 with iron sheet makes it easier to be magnetically attracted and driven by magnet 131. Moreover, iron sheet is easy to process into folded edges 211. Compared with making the blade 210 with magnet, it is lower in cost and easier to process.

[0033] For example, there are two guide channels 220, which are centrally symmetrically arranged around the center of the guide section 200. There are two spray nozzles 320, which are respectively arranged above the ends of the two guide channels 220. When the blade 210 rotates, the folded edge 211 can push the water to the edge of the guide section 200. The two centrally symmetrical guide channels 220 can push the water flow to the two guide channels 220 respectively in the direction of rotation of the blade 210. The two guide channels 220 can be equipped with two corresponding spray nozzles 320 to enhance the water spraying efficiency.

[0034] For example, the end of the guide channel 220 is provided with an arc-shaped guide surface 221 that bends toward the spray nozzle 320. When water is pushed to the end of the guide channel 220, the arc-shaped guide surface 221 has a guiding function. The arc-shaped guide surface 221 that bends toward the spray nozzle 320 allows the water flow to be pushed toward the spray nozzle 320 along the arc-shaped guide surface 221 and sprayed out.

[0035] For example, the width of the guide channel 220 gradually increases from the initial end to the end. During the rotation of the blade 210, more and more water will be pushed into the guide channel 220. The width of the guide channel 220 gradually widens to accommodate more water flow. Moreover, the gradually widening inner wall of the guide channel 220 also plays a guiding role, allowing the water flow to be pushed towards the spray nozzle 320 along the guide channel 220.

[0036] For example, the end cap 300 is bent inward at the water inlet 310 to form an arc-shaped surface 311. The inward bending and concavity makes the arc-shaped surface 311 play a guiding role and increases the diameter of the outermost ring of the water inlet 310, allowing more water to be drawn in from the water inlet 310 and increasing the water intake efficiency.

[0037] For example, the flow guide 200 is magnetically attached to the partition 140 under the magnetic force of the magnet 131. The partition 140 is provided with a positioning hole 141. The flow guide 200 is inserted into the positioning hole 141 and installed by magnetic attraction. It is easy to install and remove, and it is convenient to replace the end cap 300 and the flow guide 200 with different specifications and the number of spray nozzles 320. The positioning through the positioning hole 141 can prevent the magnet 131 from rotating and causing the entire flow guide 200 to rotate together, keeping the flow guide 200 fixed.

[0038] The advantages of implementing the magnetic pump provided by this utility model compared with the prior art are as follows:

[0039] This invention draws water into the guide section 200 from the inlet 310. The water in the guide section 200 is propelled by the rotating blades 210, flowing along the guide channel 220 to its end before being sprayed out from the nozzle 320. When the rotor 110 is energized, it rotates, causing the turntable 130 to rotate, which in turn rotates the magnet 131 fixedly mounted on the turntable 130. The turntable 130 is located at the end of the rotating shaft 120 near the partition 140. During the rotation of the magnet 131, the blades 210 rotate under the magnetic attraction of the partition 140. When energized, the rotor 110 drives the rotating shaft 120 to rotate, which in turn drives the turntable 130 to rotate, causing the magnet 131 to rotate as well. The magnet 131, through the partition 140, magnetically attracts the blades 210 to rotate with it. The rotation of the blades 210 creates a vortex-shaped negative pressure zone in the center of the guide section 200. The system allows external water to be drawn into the guide section 200 through the inlet 310 at the center of the end cap 300. The rotation of the blades 210 further pushes the water within the guide section 200 to the guide groove 220 along its edge, from which it is sprayed out towards the nozzle 320. A partition 140 separates the guide section 200 from the turntable 130, preventing water from leaking onto the turntable 130 side when the guide section 200 is filled, thus protecting the rotor 110 and the shaft 120. These components prevent water ingress that could lead to electrical leakage or malfunction. Several magnets 131 are spaced apart along the center circumference on the turntable 130. This eliminates the need to make the entire turntable 130 into a magnet 131, while still achieving a magnetic attraction effect on the blades 210, saving on magnets and manufacturing costs. The turntable 130 can stably drive the magnets 131 to rotate, thereby driving the blades 210 to rotate. The structure is simple. The end cover 300 is placed on the guide section 200, and the end cover 300 is easy to install and remove.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
