Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0019] This embodiment provides an easily maintainable electromagnetic pump, such as... Figure 1As shown, it includes an inlet device 1 and an outlet device 2 that are interconnected. A quick-release device 3 is also provided between the inlet device 1 and the outlet device 2. The quick-release device 3 can quickly separate the inlet device 1 and the outlet device 2. When it is necessary to clean or maintain the inlet device 1 and the outlet device 2, the inlet device 1 and the outlet device 2 can be quickly separated directly through the quick-release device 3, which improves the efficiency of cleaning or maintenance.

[0020] Combination Figure 1 and Figure 2 As shown, the water inlet device 1 includes a water inlet pipe 10 and a first one-way valve assembly 11. The water inlet pipe 10 runs vertically through the pipe, and the bottom of the water inlet pipe 10 is provided with a water inlet 100. The water inlet 100 is connected to the water inlet end of the first one-way valve assembly 11. The first one-way valve assembly 11 is located inside the water inlet pipe 10 along the water flow direction and is used to restrict the one-way water outflow of the water inlet pipe 10.

[0021] The first one-way valve assembly 11 includes a first spring 111, a first inner water pipe 110, a second spring 112, and a first one-way valve plug 113. The first inner water pipe 110 runs vertically through the water pipe and is coaxially arranged with the inlet pipe 10. The inlet end of the first inner water pipe 110 is located at its bottom, and the outlet end of the first inner water pipe 110 is located at its top. The inlet port 100 is connected to the inlet end of the first inner water pipe 110.

[0022] The first spring 111 is located below the first inner water pipe 110. The top of the first spring 111 abuts against the bottom of the first inner water pipe 110, and the bottom of the first spring 111 abuts against the inside of the inlet pipe 10. The second spring 112 passes through the first inner water pipe 110. The bottom of the second spring 112 is fixed inside the first inner water pipe 110, and the top of the second spring 112 is fixedly connected to the first one-way valve plug 113. The second spring 112 can drive the first one-way valve plug 113 to move down to press the outlet end of the first inner water pipe 110.

[0023] The first one-way valve assembly 11 also includes an electromagnetic assembly 12, which includes an electromagnet 120, an upper iron ring 121, a middle rubber ring 122, a lower iron ring 123, and a winding assembly 124. The electromagnet 120 is fixedly sleeved on the first inner water pipe 110. The upper iron ring 121, the middle rubber ring 122, and the lower iron ring 123 are respectively wound around the outer surface of the water inlet pipe 10 and arranged in a top-middle-bottom order. The winding assembly 124 is wound around the outside of the upper iron ring 121, the middle rubber ring 122, and the lower iron ring 123, and the winding assembly 124 is electrically connected to two contact pieces 125.

[0024] When in use, when the electromagnetic component 12 is not energized, the electromagnet 120 is not subjected to electromagnetic force, and the first spring 111 is in a naturally extended state. The first spring 111 can apply an upward supporting force to the first inner water pipe 110, so that the first inner water pipe 110 maintains its initial position in the inlet pipe 10. The second spring 112 is also in a naturally extended state. The first one-way valve plug 113 connected to its top moves down under the action of the elastic force of the second spring 112, pressing the outlet end of the first inner water pipe 110, so that the outlet channel of the first inner water pipe 110 is closed. When the external water source enters from the inlet 100 at the bottom of the inlet pipe 10 and flows into the inlet end of the first inner water pipe 110, the water cannot continue to flow upward because the outlet end of the first inner water pipe 110 is blocked by the first one-way valve plug 113.

[0025] When the electromagnetic component 12 is energized, the winding group 124 generates electromagnetic force to drive the electromagnet 120 to move up and down reciprocally, thereby driving the first inner water pipe 110 to move up and down synchronously. When the electromagnet 120 drives the first inner water pipe 110 to move down, the first spring 111 is compressed and stores elastic potential energy. At this time, the downward movement of the first inner water pipe 110 reduces the volume of the water flow channel in the inlet pipe 10, which in turn causes the pressure inside the channel of the first inner water pipe 110 to increase. The impact force of the continuous upward flow of external water and the increased pressure work together to overcome the clamping force of the first one-way valve plug 113, causing the second spring 112 to extend further, thereby pushing the first one-way valve plug 113 to move up, thus forming a gap between the first one-way valve plug 113 and the outlet end of the first inner water pipe 110, allowing water to flow out from the outlet end of the first inner water pipe 110 through this gap.

[0026] When the electromagnet 120 moves the first inner water pipe 110 upward, the first spring 111 rebounds and releases its elastic potential energy, and the first inner water pipe 110 returns to its original position. At this time, the upward movement of the first inner water pipe 110 increases the volume of the water flow channel in the inlet pipe 10, resulting in a decrease in the pressure inside the first inner water pipe 110. The upward impact force of the external water source is weakened accordingly. Since the second spring 112 was previously in an extended state due to the upward movement of the one-way valve plug, it will release its elastic potential energy and contract to return to its original position. Its elastic force directly pulls the first one-way valve plug 113 downward. Since the water flow impact force is no longer sufficient to counteract the contraction force of the second spring 112, the first one-way valve plug 113 can press the outlet end of the first inner water pipe 110 again.

[0027] Combination Figure 1 and Figure 3 As shown, the water outlet device 2 includes a water outlet pipe 20 and a second one-way valve assembly 21. The water outlet pipe 20 runs vertically through the water outlet pipe, and the top of the water outlet pipe 20 is provided with a water outlet 200. The water outlet 200 is connected to the water outlet end of the second one-way valve assembly 21. The second one-way valve assembly 21 is located inside the water outlet pipe 20 along the water flow direction and is used to restrict the one-way water flow of the water outlet pipe 20.

[0028] The second one-way valve assembly 21 includes a second inner water pipe 210, a second one-way valve plug 211, and a third spring 212. The inlet end of the second inner water pipe 210 is located at the bottom of the second inner water pipe 210 and is connected to the outlet end of the first inner water pipe 110. The outlet end of the second inner water pipe 210 is located at the top of the second inner water pipe 210 and is connected to the outlet 200. The second one-way valve plug 211 is located above the second inner water pipe 210, and the third spring 212 is located above the second one-way valve plug 211. The bottom of the third spring 212 abuts against the top of the second one-way valve plug 211, and the top of the third spring 212 abuts against the inside of the second inner water pipe 210 to drive the second inner water pipe 210 to press against the top of the second inner water pipe 210.

[0029] When in use, when the electromagnetic component 12 is not energized, the first one-way valve component 11 in the water inlet device 1 can prevent water from entering the water outlet device 2; when the electromagnetic component 12 is energized, the first one-way valve plug 113 in the first one-way valve component 11 is opened, and water flows from the first inner water pipe 110 into the second inner water pipe 210. As the water flow continues to be injected, the water pressure in the second inner water pipe 210 gradually increases. When the water pressure reaches a level sufficient to overcome the elastic force of the third spring 212, it will push the second one-way valve plug 211 to move upward, causing the water outlet at the top of the second inner water pipe 210 to open, and the water flows out along the top of the second inner water pipe 210, and is finally pumped out through the water outlet 200 of the water outlet pipe 20.

[0030] Combination Figure 1 , Figure 4 and Figure 5 As shown, the quick-release device 3 is detachably connected to an upper mounting assembly 30 and a lower mounting assembly 31. The upper mounting assembly 30 is fixedly connected to the bottom of the water outlet device 2, and the lower mounting assembly 31 is fixedly connected to the top of the water inlet device 1. The upper mounting assembly 30 includes an upper connecting plate 300 and an upper outer ring 301 arranged vertically and fixedly connected. The top of the upper connecting plate 300 is sealed and fixedly connected to the bottom of the water outlet pipe 20. The side wall of the upper outer ring 301 has slots 302 penetrating through the side wall of the upper outer ring 301. Multiple slots 302 are evenly distributed circumferentially along the side wall of the upper outer ring 301, and each slot 302 contains a ball bearing 303. The upper mounting assembly 30 also includes an inner ring 304, which is fixed within the upper ring and located within the upper outer ring 301. The outer side wall of the inner ring 304 is spaced apart from the multiple ball bearings 303.

[0031] The lower mounting assembly 31 includes a lower outer ring body 310 and a support plate 313 arranged vertically and fixedly connected. The bottom of the support plate 313 is sealed and fixedly connected to the top of the water inlet pipe 10. The lower outer ring body 310 is sleeved on the upper outer ring body 301. The inner side wall of the lower outer ring is recessed and formed with a sliding groove. The sliding groove includes a vertical groove 311 and a horizontal groove 312 that are interconnected.

[0032] The upper connecting plate 300 and the support plate 313 are respectively provided with through holes that extend through their own thickness direction, and the two through holes are coaxially aligned.

[0033] In use, first align the ball bearing 303 in the upper mounting assembly 30 with the entrance of the vertical groove 311 in the lower mounting assembly 31. Then, move the upper mounting assembly 30 down. The upper outer ring 301 drives the ball bearing 303 to move down along the vertical groove 311. During this process, the ball bearing 303 will be subjected to the squeezing force of the side wall of the vertical groove 311, causing the ball bearing 303 to move towards the inner ring 304. Since the upper ring also has an inner ring 304, and the outer side of the inner ring... The gap between the wall and the ball 303 prevents the ball 303 from falling off the outer wall of the upper outer ring 301. When the ball 303 moves to the connection between the vertical groove 311 and the horizontal groove 312, the lower outer ring 310 is rotated so that the ball 303 can roll along the horizontal groove 312, so that the ball 303 moves away from the connection between the vertical groove 311 and the horizontal groove 312. At this time, the upper side wall of the horizontal groove 312 can block the upward displacement of the ball 303.
