[0034] The following will describe various specific embodiments of the present application with reference to the drawings forming a part of this specification. It should be understood that in the following drawings, the same components are denoted by the same reference numerals.

[0035] The following will describe various specific embodiments of the present application with reference to the drawings forming a part of this specification. It should be understood that although directional terms such as "upper", "lower", "left", "right", "inner", "outer", etc. are used in the present application to describe various exemplary structural parts and elements of the present application, these terms are used only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the drawings. Since the embodiments disclosed in the present application can be arranged in different directions, these directional terms are used only as illustrations and should not be construed as limitations.

[0036] Figure 1A is a perspective view of the first embodiment of the valve assembly of the present application. Figure 1B is Figure 1A the exploded view of the valve assembly shown. As Figures 1A - 1B shown, the valve assembly includes a housing 102, a valve body 112, a transmission assembly 114, a driving component 116, a first magnetic component 121, and a second magnetic component 122. The housing 102 defines a cavity 110. The valve body 112, the transmission assembly 114, the driving component 116, the first magnetic component 121, and the second magnetic component 122 are all disposed in the cavity 110. The driving component 116 can drive the valve body 112 to rotate through the transmission assembly 114, the first magnetic component 121, and the second magnetic component 122. The housing 102 includes a housing main body 104, an upper cover 106, and a partition member 108. The housing main body 104, the upper cover 106, and the partition member 108 jointly define the cavity 110.

[0037] Figure 2 is Figure 1B the perspective view of the housing main body 104 shown. As Figure 2As shown, the housing body 104 includes a first body 201, a second 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 body 201 is generally a cylindrical body with an upper opening. The first body 201 defines a first body cavity 221 with an upper opening for accommodating the valve body 112, the transmission assembly 114, and the first magnetic component 121. 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 body 201, thereby communicating with the first body cavity 221. Among them, the first pipe 211 and the second pipe 212 are generally arranged on the front side of the first body 201, the third pipe 213 is generally arranged on the left side of the first body 201, and the fourth pipe 214 and the fifth pipe 215 are generally arranged on the rear side of the first body 201. The second body 202 is arranged on the right side of the first body 201 and is connected to the first body 201. The second body 202 is generally a cuboid. The second body 202 defines a second cavity 222 with an upper opening for accommodating the driving component 116 and the second magnetic component 122.

[0038] It should be noted that although the housing body 104 shown in the present application includes five pipes, those skilled in the art can understand that the housing body 104 including at least two pipes is within the protection scope of the present application.

[0039] It should also be noted that although the first body 201 shown in the present application is generally a cylindrical body, those skilled in the art can understand that the first body 201 with other shapes is also within the protection scope of the present application.

[0040] Figure 3 Yes Figure 1B The shown housing 102 is along Figure 2 the sectional view taken along the A-A section line in Figure 3 As shown, the separator 108 is generally a flat plate. The shape of the separator 108 matches the shape of the upper opening of the second cavity 222, so that the separator 108 can cover the second body 202 and close the second cavity 222. The upper cover 106 defines an upper cover cavity 302 with a lower opening. The upper cover 106 covers the first body 201 and the separator 108, thereby closing the first body cavity 221. The upper cover cavity 302 and the first body cavity 221 together form a first cavity 311.

[0041] Thus, the housing 102 defines independent first cavity 311 and second cavity 222. The first pipe 211, the second pipe 212, the third pipe 213, the fourth pipe 214, and the fifth pipe 215 are all communicated with the first cavity 311 and are not communicated with the second cavity 222.

[0042] It should also be noted that although in this application, the first main body 201 is shown as defining a first main body cavity 221 with an upper opening, and the second main body 202 is shown as defining a second cavity 222 with an upper opening, those skilled in the art can understand that this application is not intended to limit the positions of the openings on the first main body cavity 221 and the second cavity 222.

[0043] Figure 4 Yes Figure 1B The 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 with both upper and lower ends truncated. The valve main body 402 defines a valve cavity (not shown). On the spherical surface of the valve main body 402, there are provided a first opening 411, a second opening 412, and a third opening 413. 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 311 and can rotate 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 communicating 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 311 from one of the five pipes and flow out of the first cavity 311 from another pipe. When the valve main body 402 rotates relative to the housing 102 to the disconnected 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 the embodiment of this application, the valve gear 406 is an external gear.

[0044] It should be noted that in the valve main body 402 in this application, there is only an exemplary communicating 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 communicating positions, and different communication paths can be achieved through the specific settings of the openings.

[0045] It should be noted that the valve body 402 in the present application only exemplarily has a disconnection position. However, those skilled in the art can understand that in other embodiments, the valve body 402 may not have a disconnection position.

[0046] It should be noted that although three openings are shown on the valve body 402 in the present application, those skilled in the art can understand that the valve body 402 provided with at least one opening is within the protection scope of the present application.

[0047] It should be noted that the valve body 402, valve gear 406, and valve shaft 408 in the present application can be integrally formed or can be formed by connection means (such as welding, snap connection).

[0048] Figure 5 Yes Figure 1B The 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 driving component 116 is configured to drive the first gear 501 to rotate. 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 torque of the driving component 116 is transmitted to the final gear 509 to drive the valve body 112 to rotate.

[0049] 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 of the driving component 116 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 of the driving component 116 is made greater than the torque input at the first gear 501.

[0050] 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.

[0051] 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.

[0052] Figure 6 is a front view of the drive component 116, the first magnetic component 121, the second magnetic component 122, the separator 108, and the first gear 501 of the present application, thus showing the cooperation relationship of the above components. As Figure 6 shown, the drive component 116 has an output end 601. The output end 601 can rotate around the output axis Y and has an output torque. The second magnetic component 122 is arranged on the output end 601. The first magnetic component 121 is arranged on the first gear 501 of the transmission assembly 114. The first magnetic component 121 and the second magnetic component 122 are respectively located on opposite sides of the separator 108. The first magnetic component 121 and the second magnetic component 122 are configured such that when the second magnetic component 122 rotates, the first magnetic component 121 can rotate accordingly. In other words, the first magnetic component 121 is stationary relative to the second magnetic component 122. Thus, when the second magnetic component 122 rotates, the output torque of the drive component 116 can be transmitted to the transmission assembly 114. The transmission assembly 114 is configured to be able to convert the output torque of the drive component 116 into a valve body torque that can drive the valve body 112 to rotate. Among them, the output torque is less than the valve body torque. In other words, the drive component 116 can drive the rotation of the valve body that requires a larger torque by providing a smaller torque.

[0053] In the present application, the drive component 116 is a motor. The output torque is 0.009 Nm and the valve body torque is 0.94 Nm.

[0054] As Figure 6As shown, the second magnetic component 122 drives the first magnetic component 121 to rotate through magnetic attraction. The first magnetic component 121 is arranged at a distance from the separator 108, so that no friction is generated between the first magnetic component 121 and the separator 108. The second magnetic component 122 is arranged at a distance from the separator 108, so that no friction is generated between the second magnetic component 122 and the separator 108.

[0055] It should be noted that in other embodiments, the first magnetic component 121 may contact the separator 108 and / or the second magnetic component 122 may contact the separator 108, which helps to reduce the axial force generated by the magnetic field formed by the first magnetic component 121 and the second magnetic component 122.

[0056] Figure 7 is a schematic diagram of the first embodiment of the arrangement of the first magnetic component 121 and the second magnetic component 122 of the present application. As Figure 7 shown, each of the first magnetic component 121 and the second magnetic component 122 has a first polarity N and a second polarity S. The first polarity N and the second polarity S will attract each other, so that the first polarity N and the second polarity S tend to approach each other. The first polarity N of the first magnetic component 121 faces the second polarity S of the second magnetic component 122, and the second polarity S of the first magnetic component 121 faces the first polarity N of the second magnetic component 122, so that the magnetic poles of the first magnetic component 121 and the second magnetic component 122 are arranged correspondingly to form the maximum attraction, so that when the second magnetic component 122 rotates, the first magnetic component 121 can rotate accordingly.

[0057] Figure 8 is a schematic diagram of the second embodiment of the arrangement of the first magnetic component 121 and the second magnetic component 122 of the present application. As Figure 8 shown, each of the first magnetic component 121 and the second magnetic component 122 has a first polarity N and a second polarity S. The first polarity N and the second polarity S will attract each other, so that the first polarity N and the second polarity S tend to approach each other. The first polarity N of the first magnetic component 121 faces the second polarity S of the second magnetic component 122, and the second polarity S of the first magnetic component 121 is away from the first polarity N of the second magnetic component 122. In other words, the first polarity N of the first magnetic component 121 is closer to the second polarity S of the second magnetic component 122 than the second polarity S of the first magnetic component 121, and the first polarity N of the second magnetic component 122 is farther away from the first polarity N of the first magnetic component 121 than the second polarity S of the second magnetic component 122. Since the first polarity N of the first magnetic component 121 faces the second polarity S of the second magnetic component 122, the first magnetic component 121 and the second magnetic component 122 also have an attraction force, so that when the second magnetic component 122 rotates, the first magnetic component 121 can rotate accordingly.

[0058] In the first and second embodiments of the arrangement of the above-mentioned first magnetic component 121 and second magnetic component 122, the first magnetic component 121 and the second magnetic component 122 are cylinders.

[0059] It should be noted that the first magnetic component 121 and the second magnetic component 122 in the embodiments of the present application are magnetic monomers, that is to say, each of the first magnetic component 121 and the second magnetic component 122 has only one first polarity and one second polarity. Therefore, when magnetizing the first magnetic component 121 and the second magnetic component 122, only simple magnetization is required, without the need for complex multi-pole magnetization.

[0060] It should also be noted that although only one first magnetic component 121 and one second magnetic component 122 arranged on opposite sides of the partition member 108 are shown in the embodiments of the present application, at least one first magnetic component and at least one second magnetic component are within the protection scope of the present application.

[0061] In the prior art, since the driving component 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 found that, on the one hand, the provision of the seal increases the capacity required for 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 frictional 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 larger in volume and more expensive.

[0062] The present application provides a valve assembly, which includes an independent first cavity and a second cavity, and transmits power through a first magnetic component and a second magnetic component respectively arranged in the first cavity and the second cavity. A partition member is provided between the first cavity and the second cavity, so that the fluid in the first cavity will not flow into the second cavity, and thus will not flow into the driving component arranged in the second cavity, thereby protecting the driving component while eliminating the seal.

[0063] In addition, the first magnetic component and the second magnetic component of the present application are respectively arranged on the transmission assembly and the driving component. The transmission assembly can increase the torque, so that the relatively small output torque of the driving component is converted into a relatively large valve body torque capable of driving the valve body to rotate. Since the second magnetic component drives the first magnetic component to rotate during the transmission process of relatively small torque, a relatively small attractive force between the first magnetic component and the second magnetic component can satisfy the rotation of the second magnetic component driving the first magnetic component. That is to say, a relatively small magnetic field strength between the first magnetic component and the second magnetic component can satisfy the rotation of the second magnetic component driving the first magnetic component.

[0064] Figure 9It is a cross-sectional view of the second embodiment of the valve assembly of the present application. Figure 9 The illustrated embodiment is different from Figures 1A - 7 the illustrated embodiment in that: Figure 9 the illustrated valve assembly further includes an additional plate 902. The additional plate 902 is horizontally disposed in the first cavity 311, thereby roughly dividing the first cavity 311 into two parts located on the upper and lower sides of the additional plate 902. A communication hole 904 is provided on the additional plate 902. The valve shaft 408 can pass through the communication hole 904. 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 902, 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 902.

[0065] Figures 10A - 10B It is a partial perspective view of the third embodiment of the valve assembly of the present application, Figure 10C It is a partial cross-sectional view of the third embodiment of the valve assembly of the present application, thereby showing the specific structures of the first magnetic member 121, the second magnetic member 122, and the separator 108 in the third embodiment. As Figures 10A - 10C shown, the first magnetic member 121 is a cylinder, and the second magnetic member 122 is a ring. The second magnetic member 122 can be sleeved on the first magnetic member 121. The separator 108 is substantially flat. A circular counterbore 1002 is provided on the separator 108. Specifically, the counterbore 1002 extends upward from the lower surface of the separator 108, and the counterbore 1002 does not penetrate the separator 108, so that a raised cylindrical protrusion 1004 is formed on the separator 108. The first magnetic member 121 is received in the counterbore 1002. The second magnetic member 122 is sleeved on the cylindrical protrusion 1004, and thus is sleeved on the first magnetic member 121.

[0066] Thus, in this embodiment, by sleeving the second magnetic member 122 on the first magnetic member 121, the utilization rate of the first magnetic member 121 and the second magnetic member 122 in the longitudinal space (i.e., the height direction of the first magnetic member 121 and the second magnetic member 122) is improved, so that the arrangement in the valve assembly is more compact.

[0067] Figure 11It is a schematic diagram of a third embodiment of the arrangement of the first magnetic component 121 and the second magnetic component 122 of the present application. Each of the first magnetic component 121 and the second magnetic component 122 has a first polarity N and a second polarity S. The first polarity N and the second polarity S will attract each other, so that the first polarity N and the second polarity S tend to approach each other. In the radial direction of the first magnetic component 121 and the second magnetic component 122, the first polarity N of the first magnetic component 121 faces the second polarity S of the second magnetic component 122, and the second polarity S of the first magnetic component 121 faces the first polarity N of the second magnetic component 122, so that the magnetic poles of the first magnetic component 121 and the second magnetic component 122 are arranged corresponding to each other to form the maximum attraction, so that when the second magnetic component 122 rotates, the first magnetic component 121 can rotate accordingly.

[0068] In the present application, the second magnetic component 122 is arranged on the output end 601 of the driving component 116, and the first magnetic component 121 is arranged on the first gear 501 of the transmission component 114. Thus, the first magnetic component 121 and the second magnetic component 122 do not need to be provided with other auxiliary components (for example, mounting components or alignment components for coaxially arranging the first magnetic component 121 and the second magnetic component 122) for relative positioning, thereby reducing the overall size of the valve assembly. In addition, since the second magnetic component 122 is sleeved on the first magnetic component 121, the two attractive forces received by the first magnetic component 121 and the second magnetic component 122 are the same in magnitude and opposite in direction. The attractive forces received by the first magnetic component 121 and the second magnetic component 122 do not generate a movement tendency in a non-rotating direction (for example, in a straight line direction) for them. In addition, the cost of an annular magnetic component (for example, the second magnetic component 122 in the third embodiment of the valve assembly) is lower than that of a cylindrical magnetic component (for example, the first magnetic component 121).
