Illustratively, as shown in fig. 1-4, the cover 10 may further include a liner 700. The liner 700 may cover the lower surface of the cover 400. As shown in fig. 9, the liner 700 may be provided with a second connection hole 702. The second connection hole 702 may be a threaded hole, a through hole, etc., and is not limited herein. The number of the second connection holes 702 may be one, two, or more. When the second connection hole 702 is plural, the structures of the first connection holes 270 may be the same or different. For ease of processing and manufacturing, the plurality of second connection holes 702 may be generally designed in a homogeneous structure. As shown in fig. 8, the cover 400 may be provided with a third coupling hole 440. The third connection hole 440 may be a screw hole, a through hole, etc., and is not limited herein. The third connection holes 440 may be disposed in one-to-one correspondence with the second connection holes 702. The second connection member may sequentially pass through the second connection hole 702 and the third connection hole 440 from below and be connected to the fixing base 200. The second connector (not shown) may be a fastener or other structural connector, and is not limited herein. The second connecting piece can connect the inner liner 700 and the face cover 400 to the fixing base 200, so that the fixed connection of the inner liner 700 and the face cover 400 is realized. As can be seen from the foregoing, the operator connects the fixing base 200 to the face cover 400 from above through the first connecting member, and then connects the inner liner 700 and the face cover 400 to the fixing base 200 from below the inner liner 700 through the second connecting member. The second connecting piece can connect the inner liner 700 and the face cover 400 to the fixed seat 200, so that the fixing of the inner liner 700 and the face cover is realized, and the connecting mode is simple and convenient; moreover, the upper and lower connection modes, namely the first connection piece connects the fixing seat 200 to the face cover 400 from the upper side, and the second connection piece connects the inner liner 700, the face cover 400 and the fixing seat 200 together from the lower side, so that the face cover 400 and the fixing seat 200 can be acted and fixed on two sides, the connection of the three can be more reliable, and the connection looseness caused by repeated overturning in the same direction is avoided. In addition, the second connecting piece connects the three parts in turn from the lower part, so that the connecting hole corresponding to the second connecting piece on the fixing seat 200 can be free from designing into a through hole, namely, the connecting hole is free from being exposed on the upper surface of the fixing seat 200, and the overall attractiveness of the fixing seat 200 is improved.

Illustratively, the face cover 400 may have a control panel disposed thereon. The control board may include some integrated control modules for controlling power-on, program selection, etc., without limitation. The user operates the control board outside the cover 400 and controls the structure of the connection (signal connection, wire connection, etc.) thereto. As shown in fig. 4 and 8, the face cap 400 may have a via 450. Wires connected to the display assembly may pass through the wire vias 450 and connect to the control board on the bezel 400. The control panel may be a main control panel of the cover 10, or other sub-control panels, etc., without limitation. The control board may provide power and/or control signals to the display assembly. After the wire passes through the via 450, a gap remains between the wire and the sidewall of the via 450. To ensure sealing performance, a sealant may be disposed in the via 450. The seal may fill these gaps. The type of sealant is various and is not limited herein. For example, the sealant may be a silica sol. Typically, the sealant has some flowability before it is uncured. After the gap between the wire and the sidewall of the via 450 is filled with a sealant such as a silica sol, if the cover 400 moves, the silica sol flows along with the gap, and thus the sealing property is affected; whereas silica sols typically take about a week to fully cure. To avoid free flow before the sealant is uncured, the anchor 200 may be disposed to cover a portion of the wire vias 450. The fixing base 200 covers the via 450 from above. At the stage when the sealant is just filled in the gap between the wire and the sidewall of the via 450 and is not completely solidified yet, the first connector can be used to fix the fixing base 200 and the cover 400 together, and then the fixing base 200 and the cover 400 are integrally inverted (i.e. the fixing base 200 is under and the cover 400 is over), at this time, the fixing base 200 can drag the sealant in the via 450, so as to avoid the sealant from flowing randomly. The wires may pass through the portion of the wire through hole 450 not covered by the fixing base 200. The size of the via 450 and the area of the via 450 covered by the fixing base 200 may be selected by those skilled in the art as required, as long as the sealant is prevented from flowing at will after the fixing base 200 and the face cover 400 are integrally inverted. Alternatively, the second connector may be used to fix the liner 700 to the fixing base 200 and the face cover 400 after the sealant is cured and the sealing performance is confirmed to be good. Of course, the liner 700 may be secured to the anchor mount 200 and the face cover 400 at any suitable time, as desired. In addition, the fixing base 200 can protect uncured sealant within a certain range, so that the sealing performance of the wire through hole 450 is ensured, and the time can be fully utilized to simultaneously mount other parts on the surface cover 400, so that the overall production time of the cover body 10 is shortened, and the production efficiency is improved.

For example, as shown in fig. 2, the fixing base 200 may be provided with a first limiting portion 214. The first limiting portion 214 may have ribs, grooves, snaps, or other various limiting structures, which are not limited herein. In the illustrated embodiment, the first stopper 214 is a rib provided on an outer sidewall of the inner sleeve 220, the rib extending in a vertical direction. The first limiting portion 214 and the fixing base 200 may be integrally formed or separately formed and then connected together, which is not limited herein. As shown in fig. 7A, a second limiting portion 326 may be disposed on the display assembly. The second stopper 326 may have various structures that can be engaged with the first stopper 214. For example, the first limiting portion 214 may be a rib, and the second limiting portion may be a groove structure adapted thereto. In an embodiment not shown, the first limiting portion may be a groove, and the second limiting portion may be a bead-like structure adapted thereto. For example, in embodiments where the display assembly includes the display assembly 300, the second stop 326 may be provided as a recess on the bezel 320 (as will be mentioned in more detail below) of the display assembly 300. The light shield 320 can be sleeved on the inner sleeve 220, and the wires connected to the display assembly can be aligned with the wire through holes 450 after the first limiting portion 214 is matched with the second limiting portion 326 in any embodiment. Thus, in the mounting process, the first limiting part 214 and the second limiting part 326 are matched to position the wires of the display assembly, so that the wires are prevented from deviating from the wire passing holes 450 too much in the mounting process, and the wires are prevented from being aligned to the wire passing holes 450 just by manually and repeatedly adjusting the alignment in the mounting process.

For example, as shown in fig. 1 to 4, the fixing seat 200 may include a boss 240 that is upwardly protruded. The bulge 240 may have the first receiving chamber 210 formed therein. The first receiving chamber 210 may or may not have a similar outer shape to the protrusion 240. In some embodiments, not shown, the ridge may be generally cubic and the first receiving cavity may be a generally cylindrical recess. Preferably, the ridge 240 may be generally cylindrical and the first receiving cavity 210 may be a generally cylindrical recess. The ridge 240 may have a variety of shapes, not limited herein. The first receiving cavity 210 may also be a square column-shaped groove or other shapes, which are not illustrated herein. The opening of the first receiving chamber 210 is downward. The display assembly may be located within the first receiving chamber 210. In this way, the bulge 240 of the fixing base 200 can shield the display assembly located in the first accommodating cavity 210, and plays a role in protection. The steam channel 103 may be located outside the first receiving chamber 210 to isolate the steam channel 103 from the display assembly, thereby providing thermal insulation. The face cover 400 may cover the first receiving chamber 210. Illustratively, as shown in fig. 4, a portion of the via 450 is exposed to the first receiving cavity 210. Another portion of the via 450 is covered by the anchor 200. So arranged, the first receiving cavity 210 is formed by the protrusion 240, so that the processing of the fixing base 200 can be facilitated, and the fixing base 200 can have a uniform thickness throughout. Moreover, the bulge 240 of the fixing seat 200 can play a certain role in protecting the display assembly, so that the display assembly is prevented from being knocked or crashed by foreign objects, and the service life of the display assembly is prolonged. Furthermore, the mode has the advantages of simple structure, convenient assembly and the like. On the other hand, the first accommodating cavity 210 can be covered by the face cover 400, so that the display assembly can be located in a relatively closed space, and the steam channel 103 can be prevented from being transmitted to the display assembly, and the normal operation of the display assembly is prevented from being influenced. In addition, the fixing base 200 covers another part of the via hole 450, the shielding and covering effect can still be met within a certain range, and the subsequent installation work can still be performed in the process of solidifying the sealant in the via hole 450.

In the case where the first receiving chamber 210 is provided, the first stopper 214 may be provided in the first receiving chamber 210, for example, on a sidewall of the first receiving chamber 210.

Illustratively, as shown in FIG. 10, the steam valve 100 may include a lower valve cover 120, an upper valve cover 130, and an outer valve cover 140. The valve lower cover 120 and the valve upper cover 130 may surround to form the steam channel 103. In some alternative embodiments, a first seal 150 may be provided between the lower valve cover 120 and the upper valve cover 130. The valve housing 140 may be snapped onto the upper surface of the valve upper cover 130. In some alternative embodiments, a second seal 160 may be provided between the valve housing 140 and the valve cover 130. In this way, the steam channel 103 can have good sealing performance, and steam entering the steam channel 103 is prevented from leaking out through the connection part. The valve lower cover 120 may be provided with a first through hole 121. The ridge 240 may protrude into the steam valve 100 via the first through hole 121. In this way, the ridge 240 passes through the valve lower cover 120, and the ridge 240 may be closer to the valve upper cover 130. So set up, the bump 240 can stretch into the steam valve 100 through the first through hole 121, is equivalent to shortening the distance between the top wall of the bump 240 and the valve upper cover 130, and further makes the top wall of the bump 240 be closer to the light transmission window 110 of the steam valve 100, shortens the distance from the display assembly 300 to the light transmission window 110, and improves the display effect of the display assembly 300 observed through the light transmission window 110. The protrusion 240 protruding into the steam valve 100 may reduce the overall height of the holder 200 and the steam valve 100. Furthermore, the valve housing 140 can play a certain role in protecting the valve body formed by the valve upper cover 130 and the valve lower cover 120 from the outside, so that the service life of the steam valve 100 is prolonged; but also makes the outer structure of the steam valve 100 more attractive. The valve housing 140 may be transparent.

Illustratively, as shown in fig. 10, the valve lower cover 120 may be provided with an annular flange 122 extending upward from an edge of the first through hole 121. The ridge 240 may be inserted into the space enclosed by the annular flange 122. The valve upper cover 130 may be provided with a second through hole 131. The top of the annular flange 122 may be inserted into the second through hole 131. A space is provided between the annular flange 122 and the inner side wall of the second through hole 131. The space may form the air outlet 102 of the steam channel 103. So configured, the annular flange 122 can enclose the ridge 240 within the space formed thereby, and to some extent, radially constrain the ridge 240, avoiding extensive displacement of the ridge 240 within the steam valve 100. Moreover, the bulge 240 may have a relatively independent space in the steam valve 100, and the annular flange 122 protects the bulge 240, and is also convenient for directly removing the space and disposing the space outside the steam channel 103 when designing the steam channel, so that the structure of the steam valve 100 can be simplified to a certain extent, and the design scheme of the cover 10 is simplified. The air outlet 102 of the steam channel 103 may have a ring-shaped structure. Compared with the form that a whole air is directly discharged in an annular column shape from an annular air outlet, the air entering the steam valve 100 can be guided to the annular air outlet 102 to be discharged, so that the air flow of the air outlet 102 can be greatly dispersed, and the air outlet 102 of the steam channel 103 is prevented from scalding a user; in addition, the air outlet 102 of the steam channel 103 is annular, so that the steam aesthetic degree of the steam valve 100 can be improved.

Illustratively, as shown in FIG. 10, a light transmissive window 110 may be provided in the valve housing 140. It is understood that the light transmissive window 110 may be provided on a side wall, top wall of the valve housing 140. In some embodiments, not shown, the light-transmitting window may be provided on a sidewall of the valve housing, and may be provided in a certain area. Alternatively, the light-transmitting window may be disposed on the side wall so as to extend along the circumferential direction, i.e., form an annular light-transmitting window. Alternatively, the light-transmitting window may be provided in an edge region of the top wall of the valve housing. The light-transmitting window 110 may have various shapes, and may be in the shape of a discrete star, a petal, or a coherent integral light-transmitting window, none of which are limited herein. In general, the valve upper cover 130 and the valve lower cover 120 need to have better sealing performance after being matched, which makes the machining precision of the valve upper cover 130 and the valve lower cover 120 higher in the machining process, and the machining precision is higher than that of the valve housing 140 in most cases. In this way, the light-transmitting window 110 is disposed on the valve outer cover 140, and the light-transmitting window 110 can be directly processed on the valve outer cover 140, so that the light-transmitting window 110 is prevented from being processed and manufactured on the valve body formed by the valve upper cover 130 and the valve lower cover 120, and the manufacturing complexity of the steam valve 100 is reduced.

Illustratively, as shown in fig. 2 and 3, the air outlet 102 of the steam channel 103 may enclose the light-transmitting window 110. So arranged, the light-transmitting window 110 can be positioned in the air outlet 102, and the light transmitted by the light-transmitting window 110 can indicate the approximate position of the air outlet 102 of the steam valve 100, so that a user can avoid the air outlet 102 of the steam valve 100 and avoid the hot air discharged by the air outlet 102 from being scalded; the operational safety of the cover 10 is improved.

Illustratively, as shown in fig. 2, 3 and 8, the face cover 400 may be provided with an upwardly extending annular socket 420. Seal 430 may be received within annular socket 420. Annular receptacle 420 may facilitate the installation and positioning of seal 430 to some extent. The lower end of inner sleeve 220 may be inserted into annular socket 420. In combination with the above-mentioned "the lower end of the inner sleeve 220 can abut against the upper surface of the top cover 400", it is known that the lower end of the inner sleeve 220 can abut against the sealing member 430 as well as being inserted into the annular socket 420. In this way, the inner sleeve 220 and the annular socket 420 can perform bidirectional limiting on the sealing element 430 in the up-down direction and the horizontal direction, so that the sealing element 430 can be tightly attached to the face cover 400 and the fixing seat 200, and the sealing effect is improved. Illustratively, annular socket 420 may have a configuration that is compatible with inner sleeve 220. For example, when the inner sleeve 220 is a circular tube, the annular receptacle 420 may be a circular ring. In this way, the inner sleeve 220 can be connected with the face cover 400 through the annular socket 420, so that the fixing seat 200 can be quickly connected with the face cover 400, and the connection mode is time-saving and labor-saving, simple and quick. Moreover, under the bidirectional effect of the inner sleeve 220 and the annular socket 420, the sealing member 430 is more tightly adhered to the face cover 400 and the fixing base 200, and the sealing effect of the cover body 10 is improved.

Illustratively, as shown in fig. 2 and 3, the display assembly may be supported on an annular socket 420. So arranged, annular receptacle 420 of face cover 400 bears the weight of the display assembly, providing support for the display assembly and providing some assurance of operation of the display assembly; in addition, when the display component is arranged on the fixed seat 200, more structures for supporting the display component can be prevented from being processed on the fixed seat 200, the performance requirement on the materials selected for the fixed seat 200 can be reduced, the selectable range of the materials of the fixed seat 200 is enlarged, the materials with low cost can be conveniently selected, the cost is reduced, and the efficiency is improved; in addition, a further function of the structure of annular socket 420 is added, optimizing and perfecting the design of cover 10.

For example, as shown in fig. 1 to 3, the display assembly 300 may include a light emitting element 310 and a light shield 320. The light emitting element 310 may be an LED lamp known in the art or various light emitting elements that may occur in the future, which is not limited herein. As shown in fig. 7A, the light shield 320 may include an inner light shield layer 321 and an outer light shield layer 322. The inner light shielding layer 321 and the outer light shielding layer 322 may be made of the same material or different materials; can have similar shading effect. In some embodiments, the inner light shielding layer 321 and the outer light shielding layer 322 may each be annular light shielding layers. Alternatively, in other embodiments, the inner and outer light shielding layers may have different cross-sectional shapes, which are not limited herein. The outer light shielding layer 322 may surround the inner light shielding layer 321. The inner light shielding layer 321 may be sleeved on the inner sleeve 220. The inner sleeve 220 may play a certain limiting role on the inner shading layer 321 of the shading cover 320 in the radial direction. The second stopper 326 may be provided on an inner sidewall of the inner light shielding layer 321 as shown in fig. 7A. The outer light shielding layer 322 may abut against the inner sidewall of the first receiving chamber 210. The inner sidewall of the first receiving chamber 210 may play a certain limiting role on the outer light shielding layer 322 of the light shielding cover 320 in the radial direction. By the dual action of the inner sleeve 220 and the inner side wall of the first receiving cavity 210, the movement of the light shield 320 in the radial direction is avoided. The inner light shielding layer 321 and the outer light shielding layer 322 may have a space 323 therebetween. The inner shielding layer 321 can prevent light of the light emitting element 310 from being transmitted from outside to inside through the inner shielding layer 321. The outer light shielding layer 322 can prevent light of the light emitting element 310 from being transmitted from inside to outside through the outer light shielding layer 322. The light emitting element 310 is connected to the bottom of the light shield 320 and may cover the space 323. Light emitting element 310 may be aligned with space 323. The light of the light emitting element 310 may pass through the spacer 323 to reach the light transmitting window 110. Thus, by providing the light shielding cover 320 with the above structure, the light emitted from the light emitting element 310 to the side is shielded by the inner light shielding layer 321 and the outer light shielding layer 322, and the light of the light emitting element 310 can only pass through the gap and be emitted out through the light transmitting window 110, so that the light of the light emitting element 310 finally passes through the cover 10, and the influence on the visual effect caused by the diffusion of the light emitting element 310 to the periphery when the light is inside the cover 10 is avoided.

Illustratively, a catch 324 (shown in fig. 3 and 7A) may be provided on the outer shade layer 322. As best seen in fig. 7A, the catch 324 may extend downward and curve inward of the shade 320. The hook 324 and the outer shading layer 322 may be integrally formed or separately formed and then connected together. As shown in fig. 7B, a notch 311 may be provided on the outer edge of the light emitting element 310. The hook 324 can be clamped to the notch 311. The number of hooks 324 may be one, two, three or more. The number of hooks 324 and notches 311 may be one-to-one. When the number of hooks 324 is two, the two hooks 324 may be symmetrically disposed on the outer light shielding layer 322. During installation, the light shield 320 can be first placed forward, and forward placement means that the hook 324 is located at the uppermost end of the light shield 320; then, the notch 311 of the light emitting element 310 is aligned to the position of the hook 324, the light emitting element 310 is clamped to the hook 324 from top to bottom, and the light emitting element 310 can be located inside the light shield 320; subsequently, the shade 320 is inverted, and the hook 324 is located at the lowermost end of the shade 320. In this scenario, the hook 324 may still hold the notch 311, and the light emitting element 310 is located above the hook 324, where the hook 324 may support the light emitting element 310, which is equivalent to limiting the light emitting element 310 in a downward direction by the hook 324, so as to avoid downward movement of the light emitting element 310. So set up, light-emitting component 310 can be through the pothook 324 of breach 311 joint to lens hood 320, and light-emitting component 310 is simple swift with the connection of lens hood 320, convenient to detach and change.

Illustratively, as shown in FIG. 7A, the outer light shielding layer 322 may be provided with mating protrusions 325 thereon. The fitting protrusion 325 may extend downward and protrude to the outside of the light shield 320. The engaging protrusion 325 may be an elastic member such as an elastic buckle. The engaging protrusion 325 and the outer light shielding layer 322 may be integrally formed or separately formed and then connected. The number of mating projections 325 may be one, two, or more. Preferably, the number of the fitting protrusions 325 is one. The fitting protrusion 325 may be interference-fitted with the inner wall of the first receiving chamber 210. By means of the arrangement, the fitting protrusion 325 is in interference fit with the inner wall of the first accommodating cavity 210, so that the light shield 320 and the fixing seat 200 can be firmly installed; moreover, the installation is convenient, and the time and the labor are saved; furthermore, the structure of the first accommodating cavity 210 of the fixing seat 200 is not required to be machined in a matched manner, so that the machining process of the fixing seat 200 is simplified, and the manufacturing cost is saved.

Illustratively, as shown in fig. 1-3, the display assembly 300 may further include a label plate 330. The label plate 330 may cover the spacer 323 on top of the light shield 320. The label plate 330 may have a light transmissive target display pattern thereon. It will be appreciated that light from the light emitting element 310 may be projected out of the cover 10 through the target display pattern, while other light from the light emitting element 310 directed toward the label plate 330 may not pass through areas of the label plate 330 other than the target display pattern. Thus, by providing the label plate 330, the cover 10 can present the target display pattern on the light-transmitting window 110 through the light-emitting element 310, enriching the display state of the cover 10; the aesthetic degree of the cover body 10 is improved; and the experience of the user is improved.

Illustratively, as shown in fig. 1-5, the mount 200 may further include a base plate 250. The floor 250 may extend in a lateral direction from the lower edge 242 of the ridge 240. As shown in fig. 1 to 5, the fixing base 200 may further include a flange 251. The flange 251 may extend upwardly from the outer edge of the bottom plate 250. The flange 251, the bottom plate 250, and the side walls of the ridge 240 may surround to form the second receiving chamber 230. The second receiving chamber 230 opens upward. At least a portion of the steam valve 100 may be inserted into the second accommodating chamber 230. In this way, at least a portion of the steam valve 100 may be accommodated in the second accommodating chamber 230, and the overall height of the cover 10 may be reduced; also, the soleplate 250 may support the steam valve 100, providing a supporting force for the steam valve 100. As shown in fig. 6, the bottom plate 250 may be provided with a first through hole 252. The cross section of the first through hole 252 may have a circular shape, or a ring shape, or a square shape, etc., which is not limited herein. As shown in fig. 1, the steam valve 100 may have a downwardly extending air inlet 101. The air inlet 101 may be disposed through the first through hole 252. So set up, through setting up first through-hole 252, the air inlet 101 of steam valve 100 can pass fixing base 200, does benefit to and cooks the space and realizes the intercommunication. By providing the second accommodating chamber 230, at least a portion of the steam valve 100 can be accommodated in the second accommodating chamber 230, and the overall height of the cover 10 can be reduced. In addition, the bottom plate 250 can support the steam valve 100, improving the stability of the connection of the steam valve 100 with the fixing base 200.

Illustratively, as shown in FIG. 1, the cover 10 may further include a cover trim 500. As shown in fig. 2 and 3, a cover trim 500 may cover an upper surface of the cover 400. The cover trim 500 may be attached to the cover 400 and/or the liner 700 by a variety of means, such as snap fit, or threaded connection, or adhesive, or rivet, as is known or may occur in the future. In an alternative embodiment, the cover trim 500 may be provided with mounting holes 501. The fixing base 200 may be disposed through the mounting hole 501. In some alternative embodiments, as shown in fig. 1, 5 and 6, the upper edge of the cuff 251 may be provided with a flange 253 protruding in a lateral direction. The flange 253 and the flange 251 may be integrally formed with the fixing base 200 or may be separately formed and then connected to each other, which is not limited herein. Regardless of the configuration, the edge of the mounting hole 501 may be clamped between the mount 200 and the face cover 400. That is, a portion of the fixing seat 200 may be located at an upper portion of the mounting hole 501, and the portion may be pressed against an edge of the mounting hole 501 from above, and the face cover 400 is pressed against an edge of the mounting hole 501 from below. So set up, fixing base 200 can firmly press face lid decoration 500 on face lid 400, does benefit to the whole fastness of lid 10. Moreover, the cover trim 500 can be prevented from being deformed by heat to some extent.

Illustratively, as shown in fig. 8, a second through hole 411 may be provided on the face cover 400 at a position corresponding to the inner sleeve 220. The second through hole 411 may have a circular shape, or a ring shape, or a petal shape, etc., and is not limited herein. As shown in fig. 1 to 6, a third through hole 211 may be provided at a position on the fixing base 200 corresponding to the inner sleeve 220. The third through hole 211 may have a circular shape, or a ring shape, or a petal shape, etc., and is not limited thereto. The third through hole 211 may have the same shape as the second through hole 411 or may be different from the second through hole, which is not limited herein. The second through hole 411 and the third through hole 211 may communicate through the inner sleeve 220. The fluid flowing into the third through hole 211 may be cooling water, or external cool air or other fluids, which is not limited herein. As will be described later with reference to the embodiment in which the inflow fluid is external cold air, the external cold air may enter the inner sleeve 220 of the fixing base 200 through the third through hole 211, and the inner sleeve 220 may provide a guiding function and a flowing channel for the cold air entering the third through hole 211, so that the cold air may generally flow along the extending direction of the inner sleeve 220. In some alternative embodiments, as shown in FIG. 1, the cover 10 may further include an airflow generating assembly 600. The airflow generating assembly 600 may be a known air pump 630, or various airflow generating assemblies that may occur in the future, without limitation. The airflow generating assembly 600 has an air inlet 601 and an air outlet 602. The air inlet 601 of the air flow generating assembly 600 may be in communication with the third through hole 211. Preferably, the airflow generating assembly 600 may further include an air inlet pipe 610 and an air outlet pipe 620. One end of the air intake pipe 610 may be connected to an air intake port of the air pump 630, and the other end of the air intake pipe 610 may be in communication with the face cover 400. One end of the air outlet pipe 620 may be connected to an air outlet of the air pump 630, and the other end of the air outlet pipe 620 may be connected to an air vent 701 (shown in fig. 9) of the inner liner 700, and thus to the cooking space. The fluid flowing through the third through hole 211 can flow out to the lower side of the cover 10 through the inner sleeve 220 and the second through hole 411, regardless of the presence or absence of the airflow generating assembly 600. For example, the cool air may flow into the pot body through the second through hole 411. So configured, the inner sleeve 220 may communicate with the third through hole 211 and the second through hole 411, so that the fluid entering the third through hole 211 from the outside is guided, and the fluid may sequentially pass through the third through hole 211, the inner sleeve 220, the second through hole 411 and enter the pot body. In addition, another channel through which other fluid flows can be formed through the second through hole 411 and the third through hole 211, so that other fluid can be conveniently provided for the cooking appliance applied by the cover body 10, more cooking effects and cooking functions can be realized, the functions of the cover body 10 are greatly enriched, and the experience of a user is improved. For example, the third through hole 211 and the second through hole 411 provide cool air for the cooking appliance, so that bubbles in porridge, meat stewing and the like can be blown out, and the phenomenon of pot overflow can be avoided.

For example, as shown in fig. 2 to 5, a blocking member 212 may be provided in the third through hole 211. The blocking member 212 may have a shape similar to the cross section of the third through hole 211. For example, in some embodiments, the cross-section of the third through-hole 211 may be circular, and the cross-section of the barrier 212 may also be generally circular. In some embodiments, not shown, the barrier may have a shape that is dissimilar to the cross-section of the third through-hole. For example, the third through hole may be circular in cross-section, and the blocking member may be generally square, diamond-shaped, etc. The blocking piece 212 can reduce the ventilation area of the third through hole 211 of the cover body 10, so that sundries can be prevented from falling into the third through hole 211 to a certain extent, and sundries can be prevented from entering the cover body 10 through the third through hole 211 to block the inner sleeve 220 or be released into the cooking space; further, after the blocking member 212 is provided, the overall size of the third through hole 211 may look smaller from an external view, improving the overall aesthetic appearance of the cover 10. As shown in fig. 2 and 3, the outer sidewall of the blocking member 212 may be connected to the inner sidewall of the third through hole 211 by the rib 213. The ribs 213 and the blocking member 212 may be integrally formed or separately formed and then connected together. The ribs 213 may be one, two, three or more. In some embodiments, the outer sidewall of the blocking member 212 is connected to the inner sidewall of the third through hole 211 through three ribs, and the three ribs may be circumferentially uniformly distributed on the outer sidewall of the blocking member 212 in sequence, that is, an included angle between every two adjacent ribs of the three ribs may be 120 °. Along the extension direction of the third through hole, the rib may be flush with the blocking member. Preferably, along the extending direction of the third through hole 211, the rib 213 may be slightly lower than the blocking member 212, so that the third through hole 211 may be more beautiful.

The utility model further provides a cooking appliance. The cooking appliance may include a pot and a lid 10 of any of the foregoing. The cover 10 may be openable and closable. When the cover 10 is fastened to the pot, a cooking space can be formed. The air inlet 101 of the steam valve 100 may communicate with the cooking space. Because the cover 10 has the above technical effects, the cooking appliance including the cover 10 also has the same technical effects, and the description thereof is omitted herein.
