[0029] Figure 1A Is the isometric view of the valve assembly of the present application. Figure 1B - 1C Yes Figure 1AExploded view of the valve assembly shown. As Figure 1A - 1C shown, the valve assembly includes a housing 102, a valve body 112, a transmission assembly 114, a magnetic field generating assembly 116, and an induction motion assembly 118. The valve body 112, the transmission assembly 114, the magnetic field generating assembly 116, and the induction motion assembly 118 are all disposed in the housing 102. The magnetic field generating assembly 116 is configured to be able to generate a magnetic field. The induction motion assembly 118 is configured to be able to rotate in the magnetic field generated by the magnetic field generating assembly 116. The induction motion assembly 118 can drive the valve body 112 to rotate through the transmission assembly 114. The housing 102 includes a housing main body 104 and an upper cover 106.

[0030] Figure 2A is Figure 1B - 1C the perspective view of the housing main body 104 shown. Figure 2B is Figure 1B - 1C the perspective view of the upper cover 106 shown. Figure 2C is the cross-sectional view of the housing 102 along Figure 2A the A-A line in Figure 2A and Figure 2C shown, the housing main body 104 includes a first main body 201, a second main body 202, a first pipe 211, a second pipe 212, a third pipe 213, a fourth pipe 214, and a fifth pipe 215. The first main body 201 is generally a cylindrical body with an upper opening. The first main body 201 defines a first main body cavity 221 with an upper opening for accommodating the valve body 112. The first pipe 211, the second pipe 212, the third pipe 213, the fourth pipe 214, and the fifth pipe 215 are all hollow pipes and are all connected to the first main body 201, so as to communicate with the first main body cavity 221. Among them, the first pipe 211 and the second pipe 212 are generally disposed on the front side of the first main body 201, the third pipe 213 is generally disposed on the left side of the first main body 201, and the fourth pipe 214 and the fifth pipe 215 are generally disposed on the rear side of the first main body 201. The second main body 202 is disposed on the right side of the first main body 201 and is connected to the first main body 201. The second main body 202 is generally a cuboid. The second main body 202 defines a second main body cavity 222 with an upper opening. A partition 232 is provided in the second main body cavity 222. The partition 232 is annular. The partition 232 divides the second main body cavity 222 into a generally cylindrical inner cavity 241 and a generally annular outer cavity 242.

[0031] As Figure 2B and Figure 2CAs shown, the upper cover 106 includes a cover top 252, cover side portions 254, and an upper plate 256. The cover side portions 254 are formed by extending downward from the outer edge of the cover top 252, so as to enclose an upper cover cavity 259 with the cover top 252. The upper plate 256 is disposed below the cover side portions 254 and connected to the cover side portions 254. The upper plate 256 is disposed substantially parallel to the cover top 252 and partially overlaps it. In the overlapping portion of the upper plate 256 and the cover top 252, through holes 258 are formed in the upper plate 256. The shape and size of the through holes 258 match the shape and size of the separator 232, so that when the upper plate 256 abuts against the separator 232, the content cavity 241 is not blocked.

[0032] As Figure 2C shown, when the upper cover 106 is placed on the housing main body 104, the upper cover cavity 259 communicates with the first main body cavity 221, and the content cavity 241 communicates with the upper cover cavity 259 via the through holes 258. Thus, the upper cover cavity 259, the first main body cavity 221, and the content cavity 241 form a first cavity 261. The first cavity 261 is used to accommodate the induction motion assembly 118. When the upper cover 106 is placed on the housing main body 104, the upper plate 256 abuts against the separator 232, and an annular outer cavity 242 forms a second cavity 262 that is independent of the first cavity 261. The second cavity 262 is used to accommodate the magnetic field generating assembly 116, the transmission assembly 114, and the valve body 112. The second cavity 262 is disposed around at least a part (i.e., the content cavity 241) of the first cavity 261.

[0033] It should be noted that although the housing main body 104 shown in the present application includes five tubes, those skilled in the art can understand that the housing main body 104 including at least two tubes is within the protection scope of the present application.

[0034] It should also be noted that although the first main body 201 shown in the present application is substantially a cylindrical body, those skilled in the art can understand that the first main body 201 with other shapes is also within the protection scope of the present application.

[0035] It should further be noted that although the first main body 201 shown in the present application defines a first main body cavity 221 having an upper opening, and the second main body 202 defines a second main body cavity 222 having an upper opening, those skilled in the art can understand that the present application does not aim to limit the positions of the openings of the first main body cavity 221 and the second main body cavity 222.

[0036] Figure 3A is as Figure 1B shown in the perspective view of the magnetic field generating assembly 116 and the induction motion assembly 118. Figure 3B is a cross-sectional view of the magnetic field generating assembly 116, the induction motion assembly 118, and the housing 102 along Figure 2C the B-B section line shown in.Figure 3C The magnetic field generating component 116, the induction motion component 118 and the housing 102 are connected to each other. Figure 2A Cross-sectional view of line AA. Figure 3A - 3C As shown, the magnetic field generating assembly 116 is configured to generate a magnetic field after being energized. Specifically, the magnetic field generating assembly 116 is disposed in the second cavity 262. The magnetic field generating assembly 116 includes a core 302 and a plurality of windings 304 (not shown). Figure 3A As shown in Figure 3B - 3C ). The core 302 is roughly annular and extends in the up-down direction. The core 302 is arranged around the separator 232 along a first direction (i.e., the circumferential direction of the core 302). Each of the plurality of windings 304 is arranged around the core 302 along a second direction different from the first direction (i.e., the annular direction on the longitudinal plane). In other words, the annular core 302 is sleeved on the outside of the annular separator 232. Each of the plurality of windings 304 extends upward from the inside of the core 302 in a vertical direction, passes over the core 302, and then extends downward in a vertical direction, repeatedly wrapping around the core 302. Each winding is arranged roughly along the radial direction of the core 302.

[0037] like Figure 3A - 3C As shown, in this application, a plurality of ribs 306 are provided on an annular core 302. Each of the plurality of ribs 306 is provided on the core 302 and extends radially inward from the inner surface of the core 302. The plurality of ribs 306 are evenly spaced in the circumferential direction of the core 302. Subspaces 308 are formed between adjacent ribs 306 for accommodating the windings 304, thereby enabling the plurality of windings 304 to be evenly spaced in the circumferential direction of the core 302. As an example, the core 302 and the ribs 306 are made of electric furnace steel.

[0038] like Figure 3A - 3C As shown, the inductive motion assembly 118 is generally cylindrical. The inductive motion assembly 118 includes a magnetic body. The magnetic body is configured such that when the magnetic field generating assembly 116 surrounds the magnetic body, the magnetic field generated by the magnetic field generating assembly 116 can drive the inductive motion assembly 118 to rotate axially about the core 302. The end 312 of the inductive motion assembly 118 is configured to connect to the transmission assembly 114, thereby driving the transmission assembly 114 to move. As an example, the magnetic body is made of steel.

[0039] It should be noted that, although the present application shows that a plurality of ribs 306 are provided on the core 302 , in other embodiments, the core 302 may not be provided with ribs 306 .

[0040] It should also be noted that, although the present application shows that the magnetic field generating assembly 116 includes several windings 304 , any magnetic field generating assembly 116 including at least two windings 304 is within the protection scope of the present application.

[0041] Figure 4 is Figure 1B a perspective view of the valve body 112 shown. As Figure 4 shown, the valve body 112 includes a valve main body 402, a valve gear 406, and a valve shaft 408. The valve main body 402 is generally a spherical shape truncated at both upper and lower ends. The valve main body 402 defines a valve cavity (not shown). A first opening 411, a second opening 412, and a third opening 413 are provided on the spherical surface of the valve main body 402. The first opening 411, the second opening 412, and the third opening 413 are all in communication with the valve cavity. The valve main body 402 is disposed in the first cavity 261 and is capable of rotating relative to the housing 102 about the axis X of the valve body 112. When the valve main body 402 rotates relative to the housing 102 to the communication position, two of the first opening 411, the second opening 412, and the third opening 413 on the valve main body 402 are respectively in communication with two of the first pipe 211, the second pipe 212, the third pipe 213, the fourth pipe 214, and the fifth pipe 215, thereby forming a communication path to communicate at least two of the five pipes. In other words, two of the first opening 411, the second opening 412, and the third opening 413 on the valve main body 402 can enable fluid to flow into the first cavity 261 from one of the five pipes and flow out of the first cavity 261 from another pipe. When the valve main body 402 rotates relative to the housing 102 to the disconnection position, the valve main body 402 can block the first pipe 211, the second pipe 212, the third pipe 213, the fourth pipe 214, and the fifth pipe 215, thereby preventing fluid from flowing through the valve assembly. The valve shaft 408 is disposed above the valve main body 402, extends upward from the valve main body 402, and is coaxially disposed with the valve main body 402. The valve gear 406 is disposed above the valve main body 402, is coaxially disposed with and connected to the valve shaft 408. In an embodiment of the present application, the valve gear 406 is an external gear.

[0042] It should be noted that in the present application, the valve main body 402 only exemplarily has one communication position, so that two of the openings on the valve main body 402 are respectively in communication with two of the pipes, thereby forming a communication path. However, those skilled in the art can understand that in other embodiments, the valve main body 402 can have multiple communication positions and different communication paths can be achieved through specific settings of the openings.

[0043] It should be noted that in the present application, the valve main body 402 only exemplarily has one disconnection position, but those skilled in the art can understand that in other embodiments, the valve main body 402 may not have a disconnection position.

[0044] It should be noted that although three openings are shown provided on the valve main body 402 in the present application, those skilled in the art can understand that the valve main body 402 provided with at least one opening is within the protection scope of the present application.

[0045] It should be noted that although the valve body 402, valve gear 406 and valve shaft 408 shown in the present application are integrally formed, those skilled in the art can understand that the valve body 402, valve gear 406 and valve shaft 408 connected by other connection structures (such as welding, snap connection) are all within the protection scope of the present application.

[0046] Figure 5 Yes Figure 1B is a perspective view of the transmission assembly 114 shown. The transmission assembly 114 is configured to be able to transmit and increase torque. As Figure 5 shown, the transmission assembly 114 includes a first gear 501, a second gear 502, a third gear 503, a fourth gear 504, a fifth gear 505, a sixth gear 506, a seventh gear 507, an eighth gear 508 and a final gear 509. The first gear 501, second gear 502, third gear 503, fourth gear 504, fifth gear 505, sixth gear 506, seventh gear 507, eighth gear 508 and final gear 509 are all external gears. The final gear 509 is configured to be externally meshed with the valve gear 406, and the induction motion assembly 118 is configured to drive the first gear 501 to rotate. Specifically, the end 312 of the induction motion assembly 118 is connected to the first gear 501. The first gear 501 is externally meshed with the second gear 502, the third gear 503 is externally meshed with the fourth gear 504, the fifth gear 505 is externally meshed with the sixth gear 506, and the seventh gear 507 is externally meshed with the eighth gear 508. The second gear 502 is connected to the third gear 503 and coaxially arranged, the fourth gear 504 is connected to the fifth gear 505 and coaxially arranged, the sixth gear 506 is connected to the seventh gear 507 and coaxially arranged, and the eighth gear 508 is connected to the final gear 509 and coaxially arranged. Thus, the rotation of the first gear 501 can drive the rotation of the final gear 509, so that the rotation of the induction motion assembly 118 drives the rotation of the valve body 112.

[0047] In addition, the transmission assembly 114 is configured to be able to increase torque. In one embodiment, by setting the number of teeth of the gears in the transmission assembly 114, the torque output at the final gear 509 is made greater than the torque input at the first gear 501. In another embodiment, by setting the diameters of the gears in the transmission assembly 114, the torque output at the final gear 509 is made greater than the torque input at the first gear 501.

[0048] It should be noted that although the transmission assembly 114 shown in the present application includes a first gear 501, a last gear 509, and seven intermediate gears, those skilled in the art can understand that the transmission assembly 114 may include at least one intermediate gear, and the first gear 501 can drive the last gear 509 to rotate through at least one intermediate gear. In another embodiment, the transmission assembly 114 may not include an intermediate gear and only includes the meshing first gear 501 and last gear 509.

[0049] It should be noted that although the gears in the transmission assembly 114 and the valve gear 406 shown in the present application are all external gears, those skilled in the art can understand that the gears in the transmission assembly 114 and the valve gear 406 can be various forms of gears. For example, in one embodiment, at least one of the gears in the transmission assembly 114 and the valve gear 406 is an internal gear. In another embodiment, the first gear 501 is a worm and the last gear 509 is a turbine.

[0050] In the prior art, since the driving component (for example, a motor) cannot contact the fluid, a seal needs to be provided in the housing to separate the fluid from the driving component. The inventors of the present application have found that, on the one hand, the setting of the seal will increase the required capacity of the housing, resulting in a relatively large volume of the valve assembly. In addition, the seal needs to be manufactured and assembled separately, increasing the production cost. On the other hand, since the seal is provided between the housing and the valve body, the rotation of the valve body needs to overcome the friction force generated by the seal. Therefore, the driving component needs to provide a relatively large torque. A driving component capable of outputting a relatively large torque is more expensive.

[0051] The present application provides a valve assembly, which includes an independent first cavity and a second cavity, and generates power through an induction motion assembly and a magnetic field generating assembly respectively arranged in the first cavity and the second cavity to drive the valve body to rotate. A partition is provided between the first cavity and the second cavity, so the fluid in the first cavity will not flow into the second cavity and will not contact the magnetic field generating assembly arranged in the second cavity, thus protecting the magnetic field generating assembly while eliminating the seal.

[0052] Figure 6 is a cross-sectional view of the second embodiment of the valve assembly of the present application. Figure 6 The shown second embodiment is different from Figure 1A - Figure 5 the shown first embodiment in that: Figure 6The valve assembly shown further includes an additional plate 602. The additional plate 602 is disposed transversely in the first cavity 261, thereby generally dividing the first cavity 261 into two parts located on the upper and lower sides of the additional plate 602. A communication hole 604 is provided on the additional plate 602. The valve shaft 408 can pass through the communication hole 604. The valve body 402 and the valve gear 406 are respectively disposed on opposite sides (i.e., the upper and lower sides) of the additional plate 602, and the valve body 402 and the transmission assembly 114 are respectively disposed on opposite sides (i.e., the upper and lower sides) of the additional plate 602.

Additionally, the technical effects and / or technical problems described in this specification are exemplary rather than restrictive; so the disclosure in this specification may be used to solve other technical problems and have other technical effects and / or may solve other technical problems. Therefore, the examples of the embodiments of the present disclosure as stated above are intended to be illustrative rather than restrictive.
