Description

Technical Field

[0001] The present application relates to the technical field of small household appliances, and in particular to a food processor. Background Art

[0002] A food processor mixing cup and a machine head. The machine head includes a machine head seat, a motor and a stirring member. The machine head seat includes a receiving cavity. The motor is fixed in the receiving cavity of the machine head seat. The stirring member is connected to the motor shaft of the motor and is located outside the machine head seat. The rotation of the motor drives the stirring member to rotate in the mixing cup, thereby processing ingredients to obtain food, such as soy milk, juice, etc.

[0003] In the above-mentioned food processor, since the motor is fixed in the accommodating cavity of the machine head seat, the rotation speed of the motor is constant (or only within a certain range), and therefore, it cannot meet more needs. Utility Model Content

[0004] The purpose of the present application is to disclose a food processor that can meet various cooking needs by replacing a motor component.

[0005] The present application discloses a food processor. The food processor includes a blending cup, a head base and at least two motor assemblies, wherein each motor assembly includes a motor and a blending member that can be driven by the motor. The motor assembly can be assembled with the head base interchangeably, and in the assembled state, the head base covers the blending cup. The head base includes a control panel, which is connected to the motor assembly; the head base also includes at least one of a battery and a plug, and correspondingly, at least one of the battery and the plug is connected to the control panel.

[0006] As described above, since the food processor includes a head base and at least two motor assemblies. The motor assembly can be assembled interchangeably with the head base, so that consumers can replace motor assemblies of different forms according to different cooking needs. Thus, the food processor can meet different cooking needs and provide a good user experience. In addition, the motor assembly and the head base can be disassembled into independent components for easy cleaning. When there is no external power supply, the battery serves as the power supply of the food processor and the food processor can also work. When the plug is connected to an external power supply, the external power supply serves as the power supply of the food processor and the food processor works. Therefore, regardless of whether there is an external power supply (for example, outdoors), the food processor has power and can work, and the food processor is easy to use.

[0007] In some embodiments, the motor includes a rotor assembly and a stator assembly, and the stator assembly is located inside the rotor assembly. The food processor includes a motor sealing ring, which is fixed to the stator assembly, and when the rotor assembly is stationary relative to the stator assembly, the motor sealing ring seals the rotor housing of the rotor assembly, and when the rotor assembly rotates relative to the stator assembly, there is a gap between the motor sealing ring and the rotor housing.

[0008] As described above, when the rotor assembly rotates relative to the stator assembly, there is a gap between the motor seal ring and the rotor housing. Thus, there is no friction between the rotor assembly and the motor seal ring due to the gap, the motor has a large output power, and the motor seal ring can be prevented from wearing and affecting the sealing performance, so that the stirring element can be driven better. When the rotor assembly is stationary relative to the stator assembly, the motor seal ring seals the rotor housing, which can prevent water from entering the motor and increase the life of the motor.

[0009] In some embodiments, the motor sealing ring includes a sealing ring side wall surrounding the rotor housing, and the sealing ring side wall is provided with a circle of grooves opposite to the stator assembly.

[0010] As set up above, after a circle of the grooves is provided, the weight of the side wall of the sealing ring is lighter, and when the rotor assembly rotates, the side wall of the sealing ring is more easily separated from the rotor housing to achieve the gap.

[0011] In some embodiments, the lower end of the blending cup is narrowed and has an installation step, the food processor includes a heating plate assembly and a bottom cover, the heating plate assembly is installed on the installation step, the bottom cover is locked with the heating plate assembly and pressed against the blending cup.

[0012] As set up as above, since the lower end of the blending cup is narrowed to have an installation step, the heating plate assembly can be placed downward from the top of the blending cup until the heating plate assembly is located on the installation step, and then the bottom cover and the heating plate assembly are locked so that the bottom cover and the blending cup are tightly pressed together, thereby completing the assembly of the three. The assembly of the heating plate assembly is simple and convenient.

[0013] In some embodiments, the head seat covers the mouth of the blending cup, and a material outlet is formed between the head seat and the side wall of the mouth of the cup. The food processor includes a steam valve assembly. When the steam valve assembly is assembled to the head seat, the material outlet is closed; when the steam valve assembly is removed from the head seat, the inside of the blending cup is connected to the outside of the food processor through the material outlet.

[0014] As described above, when the steam valve assembly is assembled to the head seat of the machine head, the steam valve assembly closes the discharge port. In this case, the consumer can start the food processor to process the food. The food in the mixing cup can be poured out by simply removing the steam valve assembly (at this time, the inside of the mixing cup is connected to the outside of the food processor through the discharge port) without removing the machine head. Therefore, the food processor is easy to use and has a good user experience.

[0015] In some embodiments, the steam valve assembly includes an exhaust channel and a weight member. The exhaust channel includes a first channel located in a vertical direction. The weight member is located in the first channel to open or close the first channel. Alternatively, the steam valve assembly includes an exhaust channel and an electric control valve, and the electric control valve opens or closes the exhaust channel.

[0016] As set up above, since the first channel is located in the vertical direction, and the gravity piece is located in the first channel, and the first channel is a part of the exhaust channel, when bubbles are generated in the mixing cup and enter the exhaust channel, the bubbles will burst when they hit the gravity piece, so the gravity piece plays a role in defoaming. In addition, the gravity piece can open and close the exhaust channel to adjust the air pressure in the mixing cup, which plays a role in preventing overflow. Furthermore, the gravity piece is located in the first channel and has a certain blocking effect, and thus, can play a certain role in preventing overflow. By setting the electric-controlled valve to open or close the exhaust channel, bubbles will burst when they hit the electric-controlled valve, which plays a role in defoaming. The electric-controlled valve opens or closes the exhaust channel to adjust the air pressure in the mixing cup and plays a role in preventing overflow.

[0017] In some embodiments, the steam valve assembly includes an exhaust channel, which includes a first channel and an anti-overflow chamber. Along the steam flow direction, the anti-overflow chamber is located downstream of the first channel, and the steam flow area of ​​the anti-overflow chamber is larger than the steam flow area of ​​the first channel.

[0018] As described above, since the steam flow area of ​​the overflow prevention chamber is larger than the steam flow area of ​​the first channel, the bubbles will change from gas to liquid when entering the overflow prevention chamber from the first channel. After changing to liquid, there will be no bubbles, and the slurry will not be carried away by the bubbles. Therefore, the overflow prevention chamber can play a role in defoaming and overflow prevention. In addition, the flow area of ​​the overflow prevention chamber is larger than the flow area of ​​the first channel. On the one hand, the overflow prevention chamber can temporarily store some food and also play a role in overflow prevention. On the other hand, after the area is enlarged, the food moves from a small space to a large space, which can prevent food from splashing.

[0019] In some embodiments, a notch is provided at the edge of the head seat; the steam valve assembly is detachably assembled in the notch and contacts with the notch side wall and the notch bottom of the notch.

[0020] As described above, since the steam valve assembly is in contact with the notch side wall and the notch bottom, the steam valve assembly is easy to disassemble and assemble. Moreover, through the notch side wall contacting the steam valve assembly, the three notch side walls respectively limit the steam valve assembly in three directions, thereby preventing the steam valve assembly from shaking easily.

[0021] In some embodiments, a connecting hole communicating with the interior of the blending cup is disposed at the bottom of the notch; the steam valve assembly includes an exhaust passage and an insert portion, and the exhaust passage also passes through the insert portion.

[0022] As configured above, since the insertion part is inserted into the communicating hole and seals the communicating hole, not only air leakage can be avoided, but the friction force generated by the seal can also prevent the insertion part from falling out of the communicating hole. In addition, the insertion part is inserted into the communicating hole and sealed, so that the steam valve assembly is not easy to shake. Finally, the steam valve assembly can be firmly installed in the notch.

[0023] In some embodiments, the steam valve assembly is wrapped with a valve sealing ring, and the valve sealing ring is in sealing contact with the bottom of the notch.

[0024] Since the steam valve assembly wraps the valve sealing ring, the valve sealing ring is in sealing contact with the bottom of the notch, and the connecting hole is sealed in combination with the inserting part, the sealing performance is further improved and air leakage is not easy.

[0025] In some embodiments, the head seat includes a conductive pin; the top of the motor includes a matching pin that matches the conductive pin; one of the head seat and the motor is provided with an anti-foolproof hole, and the other is provided with an anti-foolproof column; when the motor assembly is assembled to the head seat, the anti-foolproof column is inserted into the anti-foolproof hole, and accordingly, the anti-foolproof column and the anti-foolproof hole are located in the area surrounded by the line between the matching pins.

[0026] As described above, by providing the fool-proofing posts and the fool-proofing holes, incorrect plugging between the conductive plug posts and the mating pins can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] See also Figure 1 , Figure 2 and Figure 7 Combined with Figure 5 , Figure 6 , Figure 8 and Fig. 9 The present application discloses a food processor, which includes a blending cup 1 , a machine head base 21 and at least two motor components 22 . Figure 1 A first type of motor assembly 22a and a second type of motor assembly 22b are illustrated. Figure 2 , Figure 5 and Figure 6 A first motor assembly 22a is illustrated. Figure 7 , Figure 8 and Fig. 9 A second motor assembly 22b is illustrated.

[0044] Each motor assembly 22 includes a motor 221 and a stirring member 222 that can be driven by the motor 221. In the present application, for each motor assembly 22, there may be only one stirring member 222, that is, the stirring member 222 and the motor shaft of the motor 221 are non-detachably assembled; or a certain motor assembly 22 may include multiple stirring members 222, and these stirring members 222 can be used interchangeably.

[0045] The motor assembly 22 can be assembled with the headstock 21 interchangeably. Figure 2 , Figure 5 and Figure 6 The first motor assembly 22a is schematically illustrated as being assembled with the headstock 21. Figure 7 and Figure 8 The second motor assembly 22b is shown assembled with the headstock 21. Each motor assembly is assembled with the headstock 21 to form the head 2. There is no limit to how to form the head 2. Figure 1 Combined with Figure 3 and Figure 6 , the head base 21 includes an installation cavity 219. The motor assembly 22 (the first motor assembly 22a or the second motor assembly 22b) can be assembled with the head base 21 through a buckle or other structure, and inserted into the installation cavity 219. Regardless of the type of motor assembly 22, in the assembled state, the head base 21 covers the stirring cup 1, and this covering can be complete covering or partial covering as described later, for example, due to partial covering, the uncovered part constitutes the discharge port 12 (the discharge port 12 is as shown in FIG. Figure 2 , Figure 7 , Fig.11 and Fig.12 ).

[0046] Regardless of the motor assembly used in your food processor, refer to Figure 6 , Figure 7 and Figure 2 and Figure 1 , the head base 21 includes a control board 2102. The control board 2102 is connected to the motor assembly 22. In addition, the head base 21 also includes at least one of a battery 2101 and a plug, and accordingly, at least one of the battery 2101 and the plug is connected to the control board 2102. That is, when the head base 21 only includes the battery 2101, the battery 2101 is connected to the control board 2102. When the head base 21 includes the battery 2101 and the plug, the battery 2101 and the plug are both connected to the control board 2102. At this time, based on the preset program in the control board 2102, the motor 221 can be powered only by the battery 2101 to make the motor work; the motor 221 can also be connected to the mains by the plug. Of course, the battery 2101 can also be powered when the plug is connected to the mains. Of course, when the head base 21 only includes the plug, the food processor uses the mains through the plug.

[0047] As described above, since the food processor includes a head base 21 and at least two motor assemblies 22. The motor assembly 22 can be assembled interchangeably with the head base 21, so that consumers can replace motor assemblies 22 of different forms according to different cooking needs, thereby, the food processor can meet different cooking needs and provide a good user experience. In addition, the motor assembly 22 and the head base 21 can be disassembled into independent components for cleaning, which is convenient for cleaning. In addition, when the plug has no external power supply (mains power or other power supply), the battery serves as the power supply of the food processor, and the food processor can also work. When the plug is connected to an external power supply, the external power supply (mains power or other power supply) serves as the power supply of the food processor, and the food processor works. Therefore, regardless of whether there is an external power supply (for example, outdoors), the food processor has power and can work, and the food processor is easy to use.

[0048] See also Figure 6 , Figure 3 , Figure 2 and Figure 7 Combined with Figure 5 , Figure 8 and Fig. 9 The motor 221 includes a rotor assembly 2211 and a stator assembly 2212. The stator assembly 2212 is located inside the rotor assembly 2211. That is, the motor 221 is an outer rotor motor. Figure 3 Combined with Figure 6 , the food processor includes a motor sealing ring 4. The motor sealing ring 4 includes a sealing ring side wall 41 and a fixing portion 42. In an embodiment of the present application, the motor sealing ring 4 is fixed to the stator assembly 2212 through the fixing portion 42. In an embodiment of the present application, the motor sealing ring 4 is fixed to the stator assembly 2212. When the rotor assembly 2211 is stationary relative to the stator assembly 2212, the motor sealing ring 4 seals the rotor housing 22111 of the rotor assembly 2211. In an embodiment of the present application, the sealing ring side wall 41 seals the rotor housing 22111. Based on the function of the sealing ring side wall 41, the structure of the sealing ring side wall 41 is not limited. When the rotor assembly 2211 rotates relative to the stator assembly 2212, there is a gap between the motor sealing ring 4 and the rotor housing 22111, specifically, there is a gap between the sealing ring side wall 41 and the rotor housing 22111.

[0049] As described above, when the rotor assembly 2211 rotates relative to the stator assembly 2212, there is a gap between the motor seal ring 4 and the rotor housing 22111. Thus, there is no friction between the rotor assembly 2211 and the motor seal ring 4 due to the gap, the output power of the motor is large, and the motor seal ring 4 can be prevented from wearing and affecting the sealing performance, so that the stirring member 222 can be driven better. When the rotor assembly 2211 is stationary relative to the stator assembly 2212, the motor seal ring 4 seals the rotor housing 22111, which can prevent water from entering the interior of the motor 221 and increase the life of the motor 221.

[0050] The structure of the sealing ring side wall 41 in the present application is described as follows.

[0051] In an embodiment of the present application, the motor sealing ring 4 includes a sealing ring side wall 41 surrounding the rotor housing 22111 , and the sealing ring side wall 41 is provided with a circle of grooves 410 opposite to the stator assembly 2212 .

[0052] As described above, after a circle of the grooves 410 is provided, the weight of the sealing ring side wall 41 is lighter, and when the rotor assembly 2211 rotates, the sealing ring side wall 41 is more easily separated from the rotor housing 22111 to achieve the gap.

[0053] See also Figure 4 Combined with Figure 1 , Figure 2 and Figure 7 , the lower end of the blending cup 1 is narrowed and has a mounting step 13. The food processor includes a heating plate assembly 5 and a bottom cover 6. The structure of the heating plate assembly 5 is not limited, as long as it can heat the food in the blending cup 1. The heating plate assembly 5 is installed on the mounting step 13. The bottom cover 6 is locked with the heating plate assembly 5, which is not shown in the figure. For example, the bottom cover 6 and the heating plate assembly 5 are locked by screws. After the bottom cover 6 and the heating plate assembly 5 are locked, the bottom cover 6 is pressed against the blending cup 1.

[0054] As described above, since the lower end of the blending cup 1 is narrowed and has an installation step 13, the heating plate assembly 5 can be placed downward from the top of the blending cup 1 until the heating plate assembly 5 is located on the installation step 13, and then the bottom cover 6 and the heating plate assembly 5 are locked so that the bottom cover 6 and the blending cup 1 are pressed tightly to complete the assembly of the three. The assembly of the heating plate assembly 5 is simple and convenient. In the related art, the heating plate assembly 5 is assembled from the bottom to the top and is pressed tightly by the cup holder or other components.

[0055] See also Figure 2 , Figure 7 , Fig.11 and Fig.12 Combined with Figure 1 , Fig.13 and Fig.14 The head base 21 covers the mouth of the mixing cup 1, and a discharge port 12 is formed between the head base 21 and the side wall 11 of the mouth of the mixing cup. The food processor includes a steam valve assembly 3. Figure 2 and Figure 7 As shown, the steam valve assembly 3 is assembled to the headstock 21 to close the discharge port 12. Figure 2 , Figure 7 and Fig.11 and Fig.12 and Figure 1 By comparison, it can be seen that when the steam valve assembly 3 is removed from the head seat 21, the interior of the blending cup 1 is connected to the outside of the food processor through the discharge port 12. At this time, the assembly consisting of the blending cup 1 and the head 2 (except the steam valve assembly 3) can be tilted to pour out the food.

[0056] As described above, when the steam valve assembly 3 is assembled to the head seat 21 of the machine head 2, the steam valve assembly 3 closes the discharge port 12. In this case, the consumer can start the food processor to process the food. The food in the mixing cup 1 can be poured out by simply removing the steam valve assembly 3 (at this time, the inside of the mixing cup 1 is connected to the outside of the food processor through the discharge port 12) without removing the machine head 2. Therefore, the food processor is easy to use and has a good user experience.

[0057] See also Fig.14 Combined with Fig.11 , Fig.12 , Figure 1 , Figure 2 and Figure 7 , the steam valve assembly 3 includes an exhaust channel 31 and a gravity member 32. The exhaust channel 31 includes a first channel 311 located in the vertical direction. In an embodiment of the present application, the exhaust channel 31 includes a first channel 311, an anti-overflow chamber 312 and an exhaust hole 313. However, the technician can understand that in this embodiment, the exhaust channel 31 only needs to include the first channel 311 and be able to achieve exhaust. The gravity member 32 is located in the first channel 311, opening or closing the first channel 311, that is, when the pressure in the blending cup 1 is greater than the gravity of the gravity member 32, the gravity member 32 opens the first channel 311. When the pressure in the blending cup 1 is less than the gravity of the gravity member 32, the gravity member 32 closes the first channel 311.

[0058] As described above, since the first channel 311 is located in the vertical direction, and the gravity member 32 is located in the first channel 311, and the first channel 311 is a part of the exhaust channel 31, when bubbles are generated in the mixing cup 1 and enter the exhaust channel 31, the bubbles will burst when they hit the gravity member 32, so the gravity member 32 plays a role in defoaming. Furthermore, the gravity member 32 is located in the first channel 311, and has a certain blocking effect, and thus, can play a certain role in preventing overflow. In addition, the gravity member 32 can open and close the exhaust channel 31 to adjust the air pressure in the mixing cup 1 (for example, to make the air pressure inside the mixing cup 1 equal to the air pressure outside the food processor), which plays a role in preventing overflow.

[0059] Based on the function of the gravity member 32 to open or close the exhaust channel 31, in other embodiments, the steam valve assembly 3 includes an exhaust channel 31 and an electric control valve, and the electric control valve opens or closes the exhaust channel 31. That is, the electric control valve replaces the gravity member, for example, the electric control valve is a solenoid valve. In this embodiment, because the electric control valve does not need gravity to open or close the exhaust channel 31, the exhaust channel 31 may also not include the first channel 311.

[0060] As described above, by setting the electric control valve to open or close the exhaust channel 31, bubbles will burst when they hit the electric control valve, thereby playing a role in defoaming. The electric control valve opens or closes the exhaust channel 31 to adjust the air pressure in the mixing cup 1 and play a role in preventing overflow.

[0061] See also Figure 1 Combined with Fig.11 , Fig.12 , Figure 1 , Figure 2 and Figure 7 , the steam valve assembly 3 includes an exhaust channel 31. The exhaust channel 31 includes a first channel 311 and an anti-overflow chamber 312. In this embodiment, based on the subsequent function of the first channel 311, the first channel 311 may not be located in the vertical direction, as long as exhaust can be achieved. Along the steam flow direction, the anti-overflow chamber 312 is located downstream of the first channel 311, and the steam flow area of ​​the anti-overflow chamber 312 is greater than the steam flow area of ​​the first channel 311.

[0062] As described above, since the steam flow area of ​​the overflow prevention chamber 312 is larger than the steam flow area of ​​the first channel 311, bubbles will change from gas to liquid (condensation effect) when entering the overflow prevention chamber 312 from the first channel 311. After changing to liquid, there are no bubbles, and the slurry will not be carried away by the bubbles. Therefore, the overflow prevention chamber 312 can play a role in defoaming and overflow prevention. In addition, the flow area of ​​the overflow prevention chamber 312 is larger than the flow area of ​​the first channel 311. On the one hand, the overflow prevention chamber 312 can temporarily store some food and also play a role in overflow prevention. On the other hand, after the area is increased, the food moves from a small space to a large space, which can prevent food from splashing.

[0063] As follows, the relevant structures of the exhaust channel 31 and the anti-overflow chamber 312 of the steam valve assembly 3 adopted in the present application, but the technicians can understand that the structures of the exhaust channel 31, the anti-overflow chamber 312 and even the steam valve assembly 3 are not limited to the contents described below.

[0064] See also Fig.14 and Fig.13 Combined with Figure 1 , Figure 2 , Figure 7 , Fig.11 and Fig.12 The steam valve assembly 3 includes a valve cover 33 and a valve body 34. The valve cover 33 and the valve body 34 are sealed and inserted to form a cavity 35. How to seal the insertion is not limited to the embodiment of setting the valve cover sealing ring 36 as described later. The cavity 35 includes the first channel 311 and the anti-overflow cavity 312. In this embodiment, the first channel 311 may not be Figure 6 That way, it extends in the vertical direction.

[0065] As described above, the valve cover 33 and the valve body 34 are sealed and inserted to form the cavity 35. The cavity 35 includes the anti-overflow cavity 312 and the first channel 311, so that the structure of the steam valve assembly 3 is simple.

[0066] See also Fig.14 and Fig.13 The valve body 34 includes a valve body cavity 341. The side wall of the valve body cavity 341 is provided with a receiving groove 342. The valve cover 33 is sleeved with a valve cover sealing ring 36. When the valve cover 33 and the valve body 34 are inserted, the valve cover sealing ring 36 is located in the receiving groove 342.

[0067] As described above, due to the provision of the valve cover sealing ring 36 and the receiving groove 342, during the process of inserting the valve cover 33, the valve cover sealing ring 36 first contacts the side wall of the valve body cavity 341, at which time the friction force is relatively large, and when the valve cover sealing ring 36 enters the receiving groove 342, the friction force becomes smaller. The change in friction force corresponds to the change in the feel of the consumer inserting the valve cover 33, and then the consumer can know whether the valve cover 33 is assembled in place according to the change in feel. In addition, the valve cover sealing ring 36 is located in the receiving groove 342, and the blocking effect of the side wall of the receiving groove 342 also makes it difficult for the valve cover 33 to separate from the valve body 34, and the valve cover 33 is firmly assembled.

[0068] See also Fig.14 Combined with Figure 1 , Figure 2 , Figure 7 , Fig.11 and Fig.12 The anti-overflow cavity 312 and the first channel 311 have a common side wall 314, and the side wall 314 is located in a vertical direction.

[0069] As described above, since the side wall 314 shared by the overflow prevention chamber 312 and the first channel 311 is located in the vertical direction, the overflow prevention chamber 312 is arranged side by side with the first channel 311, and the steam moves upward and then turns downward, so that the path of the steam (path as shown in FIG. Figure 6 The side wall 314 is longer (as shown by the dotted arrow), which is beneficial to defoaming, overflow prevention and noise reduction. For example, a long path will reduce the steam flow rate and can reduce noise. The longer the path, the easier it is for bubbles to turn into liquid and defoam. The longer the path, the less likely it is for steam to spray out. For example, the side wall 314 can cut through bubbles and defoam in some cases. The side wall 314 is located in the vertical direction and, together with the top of the valve cover 33, blocks the movement of food into the anti-overflow cavity 312, which is beneficial to overflow prevention.

[0070] See also Figure 5 , Figure 8 and Fig. 9 Combined with Figure 1 The edge of the headstock 21 is provided with a notch 211. Figure 2 , Figure 7 and Fig.11 and Figure 1 and Fig.12 Compare and combine Figure 5 , Figure 8 and Fig. 9 It can be seen that the steam valve assembly 3 is detachably assembled in the notch 211 and contacts the notch side wall 212 and the notch bottom 213 of the notch 211 .

[0071] As described above, since the steam valve assembly 3 is in contact with the notch side wall 212 and the notch bottom 213, the steam valve assembly 3 is easy to disassemble and assemble. Moreover, through the notch side wall 212 contacting the steam valve assembly 3, the three notch side walls 212 respectively limit the steam valve assembly 3 in three directions, and thus, the steam valve assembly 3 is not easy to shake.

The steam valve assembly 3 includes an exhaust passage 31 and an insert portion 37. In the embodiment of the present application, the insert portion 37 extends downward from the bottom of the valve body 34. The exhaust passage 31 also passes through the insert portion 37, and of course, it must also pass through the bottom of the valve body 34. The insert portion 37 is inserted into the connecting hole 214 and seals the connecting hole 214. How the insert portion 37 seals the connecting hole 214, in the embodiment of the present application, see Figure 5 and Figure 6 Combined with Figure 2 and Figure 4 The steam valve assembly 3 includes a valve sealing ring 38. The valve sealing ring 38 includes a tubular portion 381, and the tubular portion 381 is sleeved with the insertion portion 37 and is provided with a convex rib 382. The tubular portion 381 and the convex rib 382 seal the gap between the insertion portion 37 and the communication hole 214, so that the insertion portion 37 seals the communication hole 214.

[0073] As configured above, since the insertion portion 37 is inserted into the connecting hole 214 and seals the connecting hole 214, not only air leakage can be avoided, but the friction force generated by the seal can also prevent the insertion portion 37 from escaping from the connecting hole 214. In addition, the insertion portion 37 is inserted into the connecting hole 214 and sealed, so that the steam valve assembly 3 is not easy to shake. Finally, the steam valve assembly 3 can be firmly installed in the notch 211.

In the embodiment of the present application, the valve sealing ring 38 also includes a valve sealing ring body 380, the tubular portion 381 extends from the valve sealing ring body 380, and the valve sealing ring body 380 seals the notch bottom 213. Of course, how to be in sealing contact with the notch bottom 213 is not limited to the embodiment described in the present application.

[0075] As configured above, since the steam valve assembly wraps the valve sealing ring 38, the valve sealing ring 38 is in sealing contact with the bottom 213 of the notch, and the connecting hole 214 is sealed in combination with the insert portion 37, the sealing performance is further improved and air leakage is not easy.
