DETAILED DESCRIPTION

[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0027] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to the inside and outside relative to the outline of the structure or component itself; "first" and "second" are used to distinguish one element from another and have no sequential order or importance. In the drawings, the direction indicated by the arrow X is the first direction, and the direction indicated by the arrow Y is the second direction. In addition, the same figure marks in different reference drawings represent the same elements.

[0028] The present invention provides a wastewater treatment device, referring to Figures 1 to 7As shown, the wastewater treatment device includes a main shell 1, a stirring mechanism 2, a driving mechanism 3, a driven mechanism 4 and a first elastic reset member 5, the stirring mechanism 2 includes a central rod 210 and a stirring assembly 220, the central rod 210 is rotatably arranged in the main shell 1, the stirring assembly 220 is located in the shell 1 and connected to the central rod 210; the driving mechanism 3 includes a driving motor 310, a first rotating disk 320 and a magnetic ring 330, the first rotating disk 320 is coaxially connected to the driving motor 310, the magnetic ring 330 is coaxially connected to the first rotating disk 320, and the driving motor 310 is used to drive the first rotating disk 320. A rotating disk 320 and a magnetic ring 330 rotate; the driven mechanism 4 includes a second rotating disk 410, a plurality of electromagnets 420 and an arc-shaped magnetic conductive plate 430. The second rotating disk 410 is coaxially fixedly sleeved on the center rod 210. The plurality of electromagnets 420 are arranged between the arc-shaped magnetic conductive plate 430 and the second rotating disk 410 at intervals along a partial circumference of the second rotating disk 410. The arc-shaped magnetic conductive plate 430 is used to magnetically cooperate with the second rotating disk 410 when the plurality of electromagnets 420 are energized, so as to rotate along the first direction when the second rotating disk 410 rotates, thereby driving the center rod 210 to rotate synchronously.

[0029] In this way, when the wastewater from the power plant is treated by the wastewater treatment device, the wastewater and the reagent can be added to the main shell 1 in advance and the drive motor 310 can be started. After the drive motor 310 is started, it will drive the first rotating disk 320 and the magnetic ring 330 to rotate. When the electromagnet 420 is energized to generate magnetism, the arc-shaped magnetic conductive plate 430 will also cooperate with the electromagnet 420 to generate magnetism. Since the multiple electromagnets 420 are arranged at intervals along the partial circumference of the second rotating disk 410, under the rotation of the first rotating disk 320 and the magnetic ring 330, the magnetic ring 330 will also magnetically attract the multiple electromagnets 420, and under the rotation of the first rotating disk 320, the second rotating disk 410 is driven to rotate a certain preset angle along the first direction, thereby being able to bring The center rod 210 and the stirring assembly 220 also rotate synchronously at the same preset angle. When the center rod 210 rotates at the preset angle, the multiple electromagnets 420 will be powered off at this time. At this time, the center rod 210, under the driving action of the first elastic reset member 5, will drive the center rod 210 to rotate in a second direction opposite to the first direction, thereby driving the stirring assembly 220 to rotate in the opposite direction, and the center rod 210 is reset. In this rotation mode, the center rod 210 will reciprocate around its own axis, thereby driving the stirring assembly 220 to swing back and forth in the main shell 1, reducing the vortex generated by the wastewater in the main shell 1, so that the medicine in the main shell 1 can be fully mixed with the wastewater, which can improve the efficiency of wastewater purification.

[0030] It should be noted that, in the above embodiment, it can be understood that: when the electromagnet 420 is energized, it drives the second rotating disk 410 to swing along the first direction, and when the electromagnet 420 is de-energized, it drives the second rotating disk 410 to swing along the second direction, and the first direction and the second direction have opposite rotation directions, which can drive the center rod 210 to swing back and forth, so as to drive the stirring assembly 220 to stir and mix the medicine and wastewater in the main shell 1.

[0031] In addition, when adding wastewater and medicine to or discharging the main shell 1, a liquid inlet and a liquid outlet can be set at any suitable position on the main shell 1. For example, a liquid inlet can be set above the main shell 1, and a liquid outlet can be set below the main shell 1. When the stirring mechanism 2 stirs and mixes the medicine and wastewater, the liquid inlet and the liquid outlet can be closed to prevent the medicine and wastewater from flowing out. The present disclosure will expand on this in detail in the subsequent embodiments and will not be elaborated here.

[0032] In some embodiments, reference Figures 1 to 7 As shown, the wastewater treatment device also includes a limiting mechanism 6, and the limiting mechanism 6 includes a limiting member 610 and a limiting groove 620. The limiting member 610 is connected to the center rod 210, and the limiting groove 620 is connected to the main shell 1. The limiting groove 620 is constructed in an arc shape and extends along the rotation direction of the center rod 210. The limiting member 610 is inserted into the limiting groove 620, and can move along the extension direction of the limiting groove 620 as the center rod 210 rotates. The limiting member 610 can be stopped at the opposite first and second ends of the limiting groove 620, and the first elastic reset member 5 is connected between the limiting member 610 and the first end of the limiting groove 620. In this way, the mutual cooperation between the limiting member 610 and the limiting groove 620 can limit the rotation stroke of the center rod 210, that is, it can be referred to Figure 5 As shown, the arc length of the arc-shaped limit groove 620 is the rotation stroke of the center rod 210, that is, the reciprocating sliding of the limit member 610 in the limit groove 620 can drive the center rod 210 to reciprocate around its own axis, and when the limit member 610 drives the center rod 210 to rotate along the first direction, the first elastic reset member 5 will also be compressed. However, in the setting of the present disclosure, the magnetic force between the electromagnet 420, the arc-shaped magnetic conductive plate 430 and the magnetic ring 330 is greater than the elastic force of the first elastic reset member 5 on the limit member 610, and the first elastic reset member 5 will not rebound the limit member 610, that is, refer to Figure 5 As shown, the limiting member 610 will be moved from the limiting groove 620 to the position under the magnetic force between the electromagnet 420 and the arc-shaped magnetic conductive plate 430 on the magnetic ring 330. Figure 5The limit member 610 moves in an arc shape upward from the bottom of the limit slot 620. When the limit member 610 moves to the top of the limit slot 620, the electromagnet 420 is powered off and the magnetic force disappears. The limit member 610 is pushed to the initial position below the limit slot 620 under the elastic force of the first elastic reset member 5 to complete a cycle of swinging. In this swinging mode, the cooperation between the limit member 610 and the limit slot 620 can make the swinging process of the center rod 210 more stable.

[0033] It should be noted that the stopper 610 mentioned in the above specific embodiments can be a structure of any suitable structure, and the present disclosure does not make any specific limitation on this. Figure 3 , Figure 4 and Figure 5 In the given embodiment, the limiting member 610 may be a limiting protrusion with a circular cross section that can be inserted into the limiting groove 620, and the limiting protrusion can slide in the limiting groove.

[0034] In addition, the first elastic reset member 5 mentioned in the above specific embodiment can also be constructed as any structure with elastic function, for example, Figure 5 In the given embodiment, the first elastic return member 5 can be a spring, one end of which is connected to one end inside the limiting groove 620, and the other end is connected to the limiting member 610, and can be bent into an arc shape along the extension direction of the limiting groove 620. In this way, the spring can also give elastic force to the limiting member 610 in the limiting groove 620.

[0035] In some embodiments, reference Figures 1 to 7As shown, the wastewater treatment device also includes a controller 7 and a first position sensor 710 and a second position sensor 720 connected to the controller 7 by signal. The first position sensor 710 is arranged at the first end, and the second position sensor 720 is arranged at the second end. The controller 7 is used to control the multiple electromagnets 420 to be powered off when the first position sensor 710 detects the limit member 610, and is used to control the multiple electromagnets 420 to be powered on when the second position sensor 720 detects the limit member 610. In this way, the first position sensor 710 and the second position sensor 720 can detect the position of the limit member 610 in the limit slot 620, and can control the electromagnet 420 to be energized or de-energized according to the position of the limit member 610 in the limit slot 620, so as to control the rotation of the second rotating disk 410 and the center rod 210, that is, it can be understood that: when the limit member 610 is at the second end of the limit slot 620 and contacts the second position sensor 720, this position can be identified as the initial position. At this time, after the second position sensor 720 receives the signal that the limit member 610 is at the second end, it controls multiple electromagnets 420 to be energized. At this time, under the magnetic force of the electromagnet 420, the arc-shaped magnetic conductive plate 430 and the magnetic ring 330, the rotation of the first rotating disk 320 will also drive the second rotating disk 410 to rotate along the first direction, that is, refer to Figure 5 As shown, at this time, the limit member 610 moves along the X direction and continuously compresses the first elastic reset member 5. After the limit member 610 moves to the second end of the limit slot 620 as the second rotating disk 410 rotates and contacts the first position sensor 710, the first position sensor 710 receives the signal that the limit member 610 is at the first end, and controls the multiple electromagnets 420 to be powered off. At this time, the magnetic forces of the electromagnets 420, the arc-shaped magnetic conductive plate 430 and the magnetic ring 330 disappear, and the limit member 610 will move along the Figure 5 The first elastic reset member 5 moves in the Y direction, the elastic force of the compression of the first elastic reset member 5 is released, and the first elastic reset member 5 will continuously push the limit member 610 to move toward the initial position, and return to the initial position again to contact the second position sensor 720 to repeat the above steps. During the repetition of the above steps, the center rod 210 will also reciprocate, and then drive the stirring assembly 220 to swing back and forth to mix the medicine and wastewater in the main housing 1, thereby improving the purification efficiency of the wastewater. Among them, the X direction is the first direction, and the Y direction is the second direction.

[0036] Furthermore, in the above-mentioned embodiment, the method of mixing the medicine and the wastewater by the reciprocating swing of the stirring component 220 can also prevent the problem of the medicine only floating on the surface of the wastewater after being spilled into the wastewater. That is, it can be understood that when the wastewater is first added to the main shell 1 and then the medicine is added, the medicine tends to float on the surface of the wastewater and cannot fully contact the wastewater. However, under the reciprocating swing of the stirring component 220, the medicine floating on the surface of the wastewater can be mixed into the wastewater more quickly, so as to purify the wastewater more quickly and improve the efficiency of the wastewater purification.

[0037] In another alternative embodiment, the reciprocating rotation of the center rod 210 can also be achieved by controlling the power-on time and power-off time of the electromagnet 420. For example, the time for the limiter 610 to move from the second end of the limit slot 620 to the first end along the first direction can be estimated. During this time, the electromagnet 420 can be powered on, and the power-on time can be calculated based on the rotation speed of the drive motor 310, the diameter of the first rotating disk 320 and the second rotating disk 410, and the arc length of the limit slot 620. The disclosure will not repeat them here. And the power-off time of the electromagnet 420 can be set by testing the time required for the limiter 610 to move from the first end of the limit slot 620 to the second end through the first elastic reset member 5 when the electromagnet 420 is powered off. Therefore, the reciprocating rotation of the center rod 210 can also be achieved by alternately turning the electromagnet 420 on and off.

[0038] In some embodiments, reference Figures 1 to 7 As shown, the center rod 210 is constructed as a hollow rod and has openings at both ends. The wastewater treatment device also includes an air charging mechanism 8, which is connected to the opening of the hollow rod outside the main shell 1. The driving mechanism 3 can drive the air charging mechanism 8 to inflate the main shell 1 through the hollow rod. In this way, when the wastewater treatment device purifies the wastewater, in addition to accelerating the mixing of the wastewater and the agent by reciprocating stirring of the stirring assembly 220, the main shell 1 can also be inflated by the air charging mechanism 8, that is, the opening of the center rod 210 constructed as a hollow rod located in the main shell 1 is inflated, so that the wastewater in the main shell 1 can be turbulent, the contact area between the wastewater and the agent can be increased, and the reaction rate can be increased, so that the agent and the wastewater can be fully mixed. In addition, the operation of the stirring mechanism 2 can be realized through the driving mechanism 3, and the operation of the air charging mechanism 8 can also be realized, which can save additional driving devices, simplify the mechanism, and reduce energy consumption.

[0039] It should be noted that in order to prevent the inflation mechanism 8 from inflating the main shell 1 with excessive pressure, which may cause the main shell 1 to explode, an air outlet (not shown in the figure) connected to the external environment can be provided in the main shell 1 to be able to discharge the air entering the main shell 1 in time. Under this arrangement, the inflation mechanism 8 can also continuously pump air into the main shell 1 to increase the turbulence of the wastewater, increase the contact area between the wastewater and the agent, and increase the reaction rate.

[0040] In addition, the inflation mechanism 8 in the present disclosure can also be constructed as any device that can cause the wastewater in the main shell 1 to surge, and the present disclosure is not limited to this. For example, the inflation mechanism 8 can be a blower or other blowing structure that can blow air into the main shell 1. The present disclosure expands on the inflation mechanism 8 in detail in subsequent embodiments, and will not go into details here.

[0041] In some embodiments, reference Figures 1 to 7 As shown, a first wedge 321 is provided on the end surface of the first rotating disk 320 facing away from the driving motor 310, and the first wedge 321 is provided with a first wedge surface 3211; the inflation mechanism 8 includes an inflation tube 810, an air bag 820 and a pressure plate assembly 830, one end of the inflation tube 810 is connected to the opening of the hollow rod located outside the main shell 1; the air bag 820 is connected to the other end of the inflation tube 810; the pressure plate assembly 830 includes a first pressure plate 831, a connecting rod 833 and a second pressure plate 832, and the two ends of the connecting rod 833 are respectively connected to the first pressure plate 831 and the second pressure plate 832, The connecting rod 833, the first pressure plate 831 and the second pressure plate 832 can move back and forth in the axial direction of the driving motor 310. The first pressure plate 831 is used to compress the airbag 820. The second pressure plate 832 is provided with a second wedge piece 8321. The second wedge piece 8321 is provided with a second wedge surface 83211 which can abut against the first wedge surface 3211. The second wedge piece 8321 can drive the first pressure plate 831 to compress the airbag 820 through the fit between the first wedge surface 3211 and the second wedge surface 83211 when the first rotating disk 320 drives the first wedge piece 321 to rotate. In this way, the inflation mechanism 8 can compress the airbag 820 by the first pressure plate 831, so that the air in the airbag 820 is blown from the inflation tube 810 to the hollow tube, and finally enters the main shell 1 to surge the wastewater and the medicine. In order to facilitate those skilled in the art to understand the inflation process, the present disclosure exemplarily describes the movement process of each component of the inflation mechanism 8, for example, it may include the following steps: Figure 4As shown, when the first wedge surface 3211 of the first wedge member 321 is not in contact with the second wedge surface 83211 of the second wedge member 8321, the second pressure plate 832 is in a lower position. When the driving motor 310 drives the first rotating disk 320 to start rotating, the first wedge member 321 also starts to make a circular motion around the rotation axis of the first rotating disk 320. At this time, the first wedge surface 3211 will continue to approach the second wedge surface 83211, that is, reaching Figure 7 When the first wedge surface 3211 is in contact with the second wedge surface 83211, the Figure 3 , the first wedge surface 3211 will gradually squeeze the second wedge piece 8321 under the rotation of the first rotating disk 320, and because the first wedge surface 3211 and the second wedge surface 83211 are arranged obliquely, when the first wedge surface 3211 is gradually squeezed, the second wedge surface 83211 will produce friction with the first wedge surface 3211, and the second wedge surface 83211 will move upward under the friction with the first wedge surface 3211, and drive the second wedge piece 8321 to move upward along the axial direction of the driving motor 310, and then drive the second pressing plate 832, the connecting rod 833 and the first pressing plate 831 to move upward, and through the first A pressure plate 831 squeezes the airbag 820. At this time, a stream of air will enter the hollow tube from the inflation tube 810 and finally enter the main shell 1. When the second wedge 8321 is lifted to the highest point, the first wedge 321 will cause the first wedge surface 3211 to separate from the second wedge surface 83211 as the first rotating disk 320 continues to rotate. At this time, the second wedge 8321 will move downward due to its own gravity or the attached second elastic reset member 841 (to be described below). In this process, the second pressure plate 832, the connecting rod and the first pressure plate 831 will also move downward, and the airbag 820 will no longer be squeezed, thereby completing an inflation process.

[0042] In some embodiments, reference Figures 1 to 7 As shown, the inflation mechanism 8 further includes a mounting shell 840, in which the airbag 820 and the first pressure plate 831 are arranged, and the connecting rod 833 is passed through the mounting shell 840. A second elastic reset member 841 is arranged between the first pressure plate 831 and the mounting shell 840, so as to provide an elastic force for the first pressure plate 831 to move toward the first rotating disk 320. In this way, the mounting shell 840 can protect the airbag 820, thereby preventing the airbag 820 from being punctured by a sharp object from the outside and causing the airbag to leak, and the second elastic reset member 841 can provide the first pressure plate 831 with an elastic force to move toward the first rotating disk 320, thereby preventing the airbag 820 from being in a compressed state all the time, and also facilitate the subsequent compression of the airbag 820 through the cooperation of the first wedge member 321 and the second wedge member 8321.

[0043] In addition, in order to further improve the smoothness of the reciprocating movement of the first pressing plate 831 in the mounting shell 840, refer to Figure 3 and Figure 4 As shown, the first pressing plate 831 may be provided with balls 842 on both sides, and the balls 842 may be connected to the first pressing plate 831 in a rolling manner, and may be rolled against the inner side wall of the mounting shell 840. In this arrangement, the first pressing plate 831 may move more smoothly along the height direction of the mounting shell 840, so as to more stably compress the airbag 820. In this way, the rotation of the first pressing plate 831 may also be limited, so that the first pressing plate 831 can only reciprocate along the axial direction.

[0044] In some embodiments, reference Figures 1 to 7 As shown, the wastewater treatment device also includes a feed pipe 230 connected to the hollow rod, and the connection between the feed pipe 230 and the hollow rod is located between the two openings. In this way, the wastewater treatment device can be filled with wastewater or medicine through the feed pipe 230, that is, the wastewater and the medicine can enter the hollow tube through the feed pipe 230 and finally enter the main shell 1 for mixing. Under this arrangement, when the wastewater and the medicine pass through the hollow tube, the wastewater and the medicine can also be pressurized by the inflation mechanism 8 to press the wastewater and the medicine into the main shell 1 faster, and it can also prevent the wastewater and the medicine from remaining in the hollow tube.

[0045] It should be noted that in order to prevent the waste water and medicine from flowing back from the feed pipe 230 and spilling out during the process of the inflation mechanism 8 inflating the hollow rod, a one-way valve can be set on the feed pipe 230 or at the water inlet 111, so that the waste water and medicine can only flow to the hollow rod. In addition, in order to prevent the waste water and medicine from being sucked back when the inflation mechanism 8 is reset, for example, when the first pressure plate 831 is reset, a one-way valve can also be set at the outlet of the inflation tube 810 or the airbag 820 to prevent back suction.

[0046] In addition, reference Figure 3 and Figure 4 As shown, a connecting pipe 240 may be provided between the feed pipe 230 and the hollow rod. The connecting pipe 240 may be a hose so as not to affect the rotation of the center rod 210 , and the inflation pipe 810 may also be a hose so as not to affect the rotation of the center rod 210 .

[0047] In some embodiments, reference Figures 1 to 7As shown, the main housing 1 is also provided with a cover 110 for covering the driving mechanism 3 and the inflation mechanism 8, and the cover 110 is provided with a water inlet 111 connected with the feeding pipe 230. In this way, the medicine and waste water can be poured into the feeding pipe 230 through the water inlet 111, and the cover 110 can also protect the driving mechanism 3 and the inflation mechanism 8, which can not only play a role in dust prevention, but also prevent the driving mechanism 3 and the inflation mechanism 8 from being bumped.

[0048] In some embodiments, reference Figures 1 to 7 As shown, the stirring assembly 220 includes an extension rod 223, a first stirring member 221 and a second stirring member 222. The number of the extension rods 223 is multiple, and one end of the extension rods 223 is connected to the central rod 210, and the other end extends in a direction away from the central rod 210. The first stirring member 221 and the second stirring member 222 are respectively connected to the ends of the extension rod 223 away from the central rod 210. In the height direction of the main shell 1, the height of the first stirring member 221 is higher than that of the second stirring member 222, and one end of the second stirring member 222 is attached to the inner bottom wall of the main shell 1. In this way, when the central rod 210 reciprocates, the first stirring member 221 and the second stirring member 222 can be driven by the extension rod 223 to reciprocate in the main shell 1, and the first stirring member 221 and the second stirring member 222 are at different heights in the main shell 1, so that the wastewater and the medicine at different positions in the main shell 1 can be reciprocated and stirred to mix the wastewater and the medicine faster.

[0049] It should be noted that the first stirring member 221 and the second stirring member 222 can be arranged in the main housing 1 in any suitable manner, for example, Figure 2 As shown, the first stirring member 221 can be a plurality of rectangular plates, one end of the extension rod 223 is connected to the central rod 210, and the other end is connected to the plurality of rectangular plates. The plurality of rectangular plates can also be connected by a connecting rod, and are arranged at intervals along the height direction of the main shell 1. The second stirring member 222 can be a parallelogram plate that can fit against the bottom wall of the main shell 1, and the bottom of the parallelogram that fits against the main shell can also be provided with a brush. Under this arrangement, the plurality of rectangular plates can stir the wastewater and the agent in the main shell 1, and the parallelogram plate at the bottom can not only stir the wastewater and the agent, but also scrub the bottom of the main shell 1 with a brush, thereby preventing waste residue in the wastewater from remaining at the bottom of the main shell, thereby improving the self-cleaning function of the wastewater treatment device.

[0050] In addition, the number of the first stirring member 221 and the second stirring member 222 can be any suitable number, which is not specifically limited in the present disclosure. Figure 2As shown, the number of the first stirring members 221 may be eight, the number of the second stirring members 222 may be two, and both are symmetrically arranged about the central rod 210 .

[0051] In some embodiments, reference Figure 2 As shown, the wastewater treatment device further includes a detection probe 9 located in the main housing 1. The detection probe 9 can detect the wastewater in the main housing 1 to ensure that the wastewater is discharged after being mixed with the reagent for purification and meets the discharge standard, so as to improve the degree of environmental protection. In the present disclosure, the detection probe 9 can also be any suitable structure, for example, it can be an organic matter sensor that can detect organic matter in the wastewater, or a heavy metal ion sensor, a suspended solid sensor, etc., and the present disclosure does not limit this.

[0052] In some embodiments, reference Figure 2 As shown, a discharge valve 113 may also be provided at the water outlet 112 of the wastewater treatment device. In this way, when the agent and wastewater are discharged from the water outlet 112, the wastewater and the agent may be discharged by opening the discharge valve 113, and when the agent and wastewater are mixed in the main housing 1, the discharge valve 113 may also seal the water outlet 112, thereby preventing the unpurified wastewater from being directly discharged from the water outlet 112.

[0053] The present disclosure exemplarily describes the specific use process of the wastewater treatment device, which may include the following steps:

[0054] First, the waste water is discharged from the feed pipe 230, and the waste water flows along the feed pipe 230 through the center rod 210 into the main shell 1. The controller 7 controls the start-up drive mechanism 3, and the drive motor 310 starts to rotate, driving the first rotating disk 320 and the magnetic ring 330 to rotate. At this time, the second position sensor 720 detects that the limit member 610 is at the second end of the limit groove 620, and controls the multiple electromagnets 420 to be energized, so that the arc-shaped magnetic conductive plate 430 is magnetically attracted to the magnetic ring 330. At this time, with the rotation of the magnetic ring 330, the second rotating disk 410 will be driven to rotate along the first direction. After the second rotating disk 410 rotates to a certain preset angle along the first direction, that is, when the limit member 610 is located at the first end of the limit groove 620 and contacts the first position sensor 710, the first position sensor 710 sends a signal to control the multiple electromagnets 420 to cut off power. At this time, the limit member 610 will return to the second end of the limit groove 620 again under the elastic force of the first elastic reset member 5. In this process, the center rod 210 will be driven to swing back and forth, thereby driving the first stirring member 221 and the second stirring member 222 in the stirring assembly 220 to swing in the main shell 1.

[0055] During the rotation of the first rotating disk 320, the inflation mechanism 8 will also inflate the main shell 1. When the first wedge surface 3211 of the first wedge member 321 is not in contact with the second wedge surface 83211 of the second wedge member 8321, the second pressure plate 832 is in a lower position. When the driving motor 310 drives the first rotating disk 320 to start rotating, the first wedge member 321 also starts to make a circular motion around the rotation axis of the first rotating disk 320. At this time, the first wedge surface 3211 will continue to approach the second wedge surface 83211, that is, it reaches Figure 7 When the first wedge surface 3211 is in contact with the second wedge surface 83211, the Figure 3 , the first wedge surface 3211 will gradually squeeze the second wedge piece 8321 under the rotation of the first rotating disk 320, and because the first wedge surface 3211 and the second wedge surface 83211 are arranged obliquely, when the first wedge surface 3211 is gradually squeezed, the second wedge surface 83211 will generate friction with the first wedge surface 3211, and the second wedge surface 83211 will move upward under the friction with the first wedge surface 3211, and drive the second wedge piece 8321 to move upward along the axial direction of the driving motor 310, and then drive the second pressure plate 832, the connecting rod 833 and the first pressure plate 831 to move upward. , and squeezes the airbag 820 through the first pressure plate 831. At this time, a stream of air will enter the hollow tube from the inflation tube 810 and finally enter the main shell 1. When the second wedge 8321 is lifted to the highest point, the first wedge 321 will allow the first wedge surface 3211 to separate from the second wedge surface 83211 as the first rotating disk 320 continues to rotate. At this time, the second wedge 8321 will move downward due to its own gravity or the second elastic reset member 841. In this process, the second pressure plate 832, the connecting rod and the first pressure plate 831 will also move downward, and the airbag 820 will not be squeezed any further, thereby completing an inflation process.
