Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a steam valve and a food crushing device. Background Technology

[0002] Taking a high-speed blender as an example, during the use of food crushing devices, the steam and moisture generated by the ingredients need to be returned and discharged through a steam valve to prevent pressure buildup and overflow.

[0003] In related technologies, a steam valve includes a valve cavity, a first air outlet on the top wall of the valve cavity, and a second air outlet on the bottom wall of the valve cavity. However, the water flowing back into the steam valve can easily form turbulence on the bottom wall of the valve cavity, which can cause noise and even cause the steam valve to vibrate, resulting in the steam valve becoming loose and shortening its service life. Utility Model Content

[0004] In view of this, the present invention provides a steam valve and a food crushing device to solve the problem in the related art that the water flowing back into the steam valve easily forms turbulence on the bottom wall of the valve cavity, which in turn causes noise and even causes the steam valve to vibrate, resulting in the steam valve becoming loose and shortening its service life.

[0005] In a first aspect, this utility model provides a steam valve, comprising:

[0006] The valve body includes a valve cavity, a first air outlet, a second air outlet, and a separator. The first air outlet is located on the top wall of the valve cavity, and the second air outlet is located on the bottom wall of the valve cavity. The bottom wall of the valve cavity has an upwardly protruding part that forms a guide slope on the bottom wall of the valve cavity. The second air outlet is located at the guide end of the guide slope. The separator is located inside the valve cavity and is used to separate the first valve cavity and the second valve cavity. The first valve cavity and the second valve cavity are arranged sequentially from top to bottom. The separator has a third air outlet that connects the first valve cavity and the second valve cavity.

[0007] Beneficial effects: During use, the steam valve of this utility model allows the steam generated by food to be discharged outward sequentially through the second steam outlet, the valve chamber, and the second steam outlet. The water flow inside the steam valve can flow smoothly downward under the guidance of the guide slope, thus flowing smoothly into the second steam outlet. This reduces water flow turbulence and helps improve drainage efficiency. It also avoids noise and vibration of the steam valve caused by turbulence, prevents the steam valve from loosening due to vibration, and helps extend the service life of the steam valve.

[0008] Based on this, the separator can divide the valve cavity into a first chamber and a second chamber. The first chamber can be used to increase the number of noise reflections in the valve cavity while ensuring normal steam outflow, so that the noise is consumed and reduced in the valve cavity. The separator is used to isolate the first chamber and the second chamber to prevent steam and water from flowing together. The second chamber can be used to guide the water flow smoothly to the second outlet.

[0009] Therefore, the steam valve in this embodiment is arranged in layers, each layer having its specific function, which helps to manage steam and water flow and reduce unnecessary turbulence.

[0010] In one alternative embodiment, the protrusion is an arc-shaped protrusion.

[0011] Beneficial effects: The smooth surface of the arc-shaped protrusion, without right angles or sharp edges, makes it less likely for steam to form eddies or turbulence when it flows through. This allows steam to transition smoothly along the curved surface, reducing local pressure loss, lowering system energy consumption, and avoiding steam stagnation in corners caused by right angles or sharp protrusions. This reduces stagnation areas and lowers the risk of scaling and corrosion.

[0012] In one alternative embodiment, the radius of curvature of the arc-shaped protrusion is r1, where 15mm ≤ r1 ≤ 20mm.

[0013] Beneficial effects: The above range is the preferred size range of the arc-shaped protrusion in the embodiment of this utility model. When the radius of curvature of the arc-shaped protrusion is within the above range, it can effectively guide the water flow to flow smoothly downward, avoid the occurrence of turbulence, and improve the overall working efficiency and stability.

[0014] In one alternative implementation, the horizontal projections of the first air outlet, the second air outlet, and the third air outlet are staggered.

[0015] Beneficial effects: This design ensures normal steam flow while guiding sound waves along an S-shape within the valve cavity, effectively dispersing the sound wave path and reducing noise. It also increases the number of reflections of sound waves within the valve cavity to dissipate some of the sound wave energy, thereby reducing noise.

[0016] In one optional embodiment, the distance between the axis of the horizontal projection of the first air outlet and the axis of the horizontal projection of the second air outlet is d1, 8mm ≤ d1 ≤ 28mm; and / or,

[0017] The distance between the axis of the horizontal projection of the second air outlet and the axis of the horizontal projection of the third air outlet is d2, 8mm≤d2≤28mm.

[0018] Beneficial effects: When the axis of the horizontal projection of the first air outlet and the axis of the horizontal projection of the second air outlet are within the above range, it can not only effectively disperse the sound wave path and reduce noise, but also consume some sound wave energy by increasing the number of reflections of the sound wave in the valve cavity, thereby achieving the effect of reducing noise.

[0019] When the distance between the horizontal projection axis of the second air outlet and the horizontal projection axis of the third air outlet is within the above range, it can not only effectively disperse the sound wave path and reduce noise, but also consume some sound wave energy by increasing the number of reflections of the sound wave in the valve cavity, thereby achieving the effect of reducing noise.

[0020] In one alternative embodiment, the separator is provided with a drain outlet, which is spaced apart from the third air outlet.

[0021] Beneficial effects: The drain outlet can effectively prevent the third vent from being blocked when steam water flows back, and can improve the smoothness and safety of the steam valve's exhaust and backflow.

[0022] In one alternative implementation, there are multiple drain outlets, which are spaced apart circumferentially along the third air outlet.

[0023] Beneficial effects: This setup helps improve drainage efficiency and ensures that if one drain is blocked, the other drains can still drain water, reducing the risk of blockage and improving system reliability.

[0024] In one alternative embodiment, the valve body includes:

[0025] The valve body has a middle cover that is placed on the valve body, and a second valve chamber is formed between the valve body and the middle cover.

[0026] The valve cover is placed on the middle cover, and the middle cover and the valve cover form the first valve cavity.

[0027] In one optional embodiment, the valve body is provided with a first engaging portion, and the middle cover is provided with a second engaging portion, wherein the first engaging portion can engage with the second engaging portion; and / or,

[0028] The middle cover is provided with a third engaging part, and the valve cover is provided with a fourth engaging part. The third engaging part can engage with the fourth engaging part.

[0029] Beneficial effects: This design makes it easier for operators to disassemble and clean the valve body, middle cover, and valve cover, preventing bacterial growth.

[0030] In one alternative implementation, the diameter of the third air outlet is d3, where 4mm ≤ d3 ≤ 8mm.

[0031] Beneficial effects: When the diameter of the third air outlet is within the above range, it can avoid excessive noise transmission, and it will not cause slow steam output due to the third air outlet being too small, resulting in excessive pressure due to untimely pressure release in the food crushing device, or blockage of the third air outlet during water discharge due to the surface tension of water.

[0032] In one alternative embodiment, the valve body further includes:

[0033] The surrounding rib is located inside the valve cavity and connected to the top wall of the valve cavity. The surrounding rib is arranged around the edge of the first air outlet.

[0034] Beneficial effects: The surrounding reinforcement can increase the number of reflections of noise waves in the valve cavity while ensuring the normal outflow of steam, thereby reducing the noise in the valve cavity and achieving a noise reduction effect.

[0035] Secondly, this utility model also provides a food crushing device, comprising:

[0036] Cup body;

[0037] A cup lid is placed on the cup body, and the cup body is provided with the steam valve provided in the first aspect of this utility model.

[0038] In one optional embodiment, the cup lid has a mounting port, a steam valve is disposed within the mounting port, and the food crushing device further includes:

[0039] The sealing ring is sandwiched between the steam valve and the inner wall of the mounting port.

[0040] Beneficial effects: The food crushing device of the second aspect of this utility model includes or uses the steam valve of the first aspect of this utility model, and therefore has its beneficial effects. That is, the steam generated by the food can be discharged outward through the second air outlet of the steam valve, the valve chamber and the second air outlet in sequence. The water flow in the steam valve can flow smoothly downward under the guidance of the guide slope, so as to smoothly flow into the second air outlet, reducing the turbulence and disturbance of the water flow, which helps to improve the drainage efficiency and avoids the noise and vibration of the steam valve caused by turbulence. It also prevents the steam valve from loosening due to vibration, which helps to extend the service life of the steam valve, and thus extend the service life of the food crushing device.

[0041] In one optional embodiment, a first snap-fit ​​protrusion is provided on the inner wall of the mounting port, and a second snap-fit ​​protrusion is provided on the outer periphery of the sealing ring. The second snap-fit ​​protrusion can pass through the inner periphery of the first snap-fit ​​protrusion and abut against the first snap-fit ​​protrusion.

[0042] Beneficial effects: With this design, the first and second locking protrusions can cooperate with each other to fasten and fix the steam valve to the mounting port, achieving a tight fixation of the steam valve, improving the reliability of the steam valve fixation, and preventing the sealing ring from wearing and deforming after long-term use, which could cause steam leakage or loosening of the steam valve.

[0061] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0062] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0063] According to an embodiment of the present invention, a steam valve 1 is provided, including a valve body 101.

[0064] The valve body 101 includes a valve cavity 1011, a first air outlet 1012, a second air outlet 1013, and a separator 1016. The first air outlet 1012 is located on the top wall of the valve cavity 1011, and the second air outlet 1013 is located on the bottom wall of the valve cavity 1011. The bottom wall of the valve cavity 1011 has an upwardly protruding protrusion 1014, which forms a flow guiding slope 1015 on the bottom wall of the valve cavity 1011. The second air outlet 1013 is located at the flow guiding end of the flow guiding slope 1015.

[0065] A separator 1016 is disposed within the valve chamber 1011 to divide the valve chamber 1011 into a first valve chamber 10111 and a second valve chamber 10112. The first valve chamber 10111 and the second valve chamber 10112 are arranged sequentially from top to bottom. The separator 1016 is provided with a third air outlet 10161, which connects the first valve chamber 10111 and the second valve chamber 10112.

[0066] In the use of the steam valve of this utility model embodiment, the steam generated by food can be discharged outward sequentially through the second air outlet 1013, the valve chamber 1011, and the second air outlet 1013. The water flow inside the steam valve can flow smoothly downward under the guidance of the guide slope 1015, thereby smoothly flowing into the second air outlet 1013. This reduces the turbulence and disturbance of the water flow, helps to improve drainage efficiency, and avoids noise and vibration of the steam valve caused by turbulence. It also prevents the steam valve from loosening due to vibration and helps to extend the service life of the steam valve.

[0067] Based on this, the separator 1016 can divide the valve cavity 1011 into a first chamber and a second chamber. The first chamber can be used to increase the number of noise reflections in the valve cavity 1011 while ensuring the normal outflow of steam, so that the noise is consumed and reduced in the valve cavity 1011. The separator 1016 is used to isolate the first chamber and the second chamber to prevent steam and water from flowing together. The second chamber can be used to guide the water flow smoothly to the second air outlet 1013.

[0068] Therefore, the steam valve in this embodiment is arranged in layers, each layer having its specific function, which helps to manage steam and water flow and reduce unnecessary turbulence.

[0069] In one embodiment, such as Figure 4 As shown, the protrusion 1014 is an arc-shaped protrusion.

[0070] The arc-shaped protrusion 1014 has a smooth surface without right angles or sharp edges, making it less likely for steam to form eddies or turbulence when it flows through. This allows steam to transition smoothly along the curved surface, reducing local pressure loss, lowering system energy consumption, and avoiding steam stagnation in corners caused by right angles or sharp protrusions. This reduces stagnation areas and lowers the risk of scaling and corrosion.

[0071] Based on this, during operation, the bottom wall of the steam valve is subjected to pressure impacts from the internal steam. The arc-shaped raised curved surface structure can evenly distribute the pressure across the entire bottom wall, preventing stress concentration at the connection between the raised part and the bottom wall, thereby dispersing stress and improving the steam valve's impact resistance.

[0072] As an alternative implementation, in embodiments not shown in the accompanying drawings, the protrusion 1014 may also be a cone, a pyramid, or a frustum structure, etc.

[0073] In one embodiment, such as Figure 6 As shown, the radius of curvature of the arc-shaped protrusion is r1, 15mm≤r1≤20mm.

[0074] The above range is the preferred size range of the arc-shaped protrusion in the embodiment of this utility model. When the radius of curvature of the arc-shaped protrusion is within the above range, it can effectively guide the water flow to flow smoothly downwards, avoid the occurrence of turbulence, and improve the overall working efficiency and stability.

[0075] In one embodiment, the horizontal projections of the first air outlet 1012, the second air outlet 1013, and the third air outlet 10161 are misaligned.

[0076] This design ensures normal steam flow while guiding sound waves along an S-shape within the valve cavity 1011, effectively dispersing the sound wave path and reducing noise. It also dissipates some sound wave energy by increasing the number of reflections within the valve cavity 1011, thereby reducing noise.

[0077] As a possible implementation, in an embodiment not shown in the accompanying drawings, the horizontal projections of the first air outlet 1012 and the second air outlet at least partially overlap, and the horizontal projection of the third air outlet 10161 is offset from the horizontal projection of the first air outlet 1012.

[0078] As an alternative implementation, in another embodiment not shown in the accompanying drawings, the horizontal projections of the first air outlet 1012, the second air outlet 1013, and the third air outlet 10161 at least partially overlap.

[0079] In one embodiment, the distance between the axis of the horizontal projection of the first air outlet 1012 and the axis of the horizontal projection of the second air outlet 1013 is d1, 8mm≤d1≤28mm.

[0080] When the axis of the horizontal projection of the first air outlet 1012 and the axis of the horizontal projection of the second air outlet 1013 are within the above range, it can not only effectively disperse the sound wave path and reduce noise, but also consume some of the sound wave energy by increasing the number of reflections of the sound wave in the valve cavity 1011, thereby achieving the effect of reducing noise.

[0081] The distance between the axis of the horizontal projection of the second air outlet 1013 and the axis of the horizontal projection of the third air outlet 10161 is d2, 8mm≤d2≤28mm.

[0082] When the distance between the axis of the horizontal projection of the second air outlet 1013 and the axis of the horizontal projection of the third air outlet 10161 is within the above range, it can not only effectively disperse the sound wave path and reduce noise, but also consume some of the sound wave energy by increasing the number of reflections of the sound wave in the valve cavity 1011, thereby achieving the effect of reducing noise.

[0083] In one embodiment, the separator 1016 is provided with a drain outlet 10162, which is spaced apart from the third air outlet 10161.

[0084] The drain outlet 10162 can effectively prevent the third vent 10161 from being blocked when steam water flows back, and can improve the smoothness and safety of the steam valve's exhaust and backflow.

[0085] In one embodiment, the size of the drain outlet 10162 is smaller than the size of the third air outlet 10161.

[0086] This design prevents steam from escaping through the drain outlet 10162, thus avoiding interference with the smooth flow within the valve chamber 1011 and preventing crossflow.

[0087] As an alternative implementation, in an embodiment not shown in the accompanying drawings, the size of the drain outlet 10162 may also be set to be the same as or larger than the size of the third air outlet 10161.

[0088] In one embodiment, there are multiple drain outlets 10162, which are spaced apart circumferentially along the third air outlet 10161.

[0089] This configuration helps improve drainage efficiency and ensures that if any drain outlet 10162 is blocked, other drain outlets 10162 can still drain water, reducing the risk of blockage of drain outlet 10162 and improving system reliability.

[0090] It should be noted that, in this embodiment of the application, the number of drain outlets 10162 is not limited.

[0091] For example, such as Figure 7 and Figure 8 As shown, in an optional embodiment, there are four drain outlets 10162, which are evenly distributed around the third air outlet 10161.

[0092] As an alternative implementation, in an embodiment not shown in the accompanying drawings, the number of drain outlets 10162 may also be three or five, etc.

[0093] In one embodiment, the valve body 101 includes a valve body 1017 and a valve cover 1018.

[0094] The separator 1016 is a middle cover that is installed on the valve body 1017. A second valve cavity 10112 is formed between the valve body 1017 and the middle cover. The valve cover 1018 is installed on the middle cover, and a first valve cavity 10111 is formed between the middle cover and the valve cover 1018.

[0095] In one embodiment, the valve body 101 includes a barrel-shaped body. The middle cover includes a first cup-lid 2 body and a first annular connecting wall. The valve body 1017 is fitted onto the outer periphery of the first annular connecting wall. The first cup-lid 2 body has a groove. The valve cover 1018 includes a second cup-lid 2 body and a second annular connecting arm, with the second annular connecting wall fitted into the groove opening.

[0096] As an alternative implementation, the valve body 101 can also be selected as an integral structure.

[0097] In one embodiment, the valve body 1017 is provided with a first engaging portion and the middle cover is provided with a second engaging portion, the first engaging portion being able to engage with the second engaging portion.

[0098] This design allows operators to easily disassemble and clean the valve body 1017 and the middle cover, preventing bacterial growth.

[0099] As an alternative implementation, in an embodiment not shown in the accompanying drawings, the connection between the valve body 1017 and the middle cover may also be a threaded connection or an interference fit, etc.

[0100] The middle cover is provided with a third engaging part, and the valve cover 1018 is provided with a fourth engaging part. The third engaging part can engage with the fourth engaging part.

[0101] This design allows operators to easily disassemble and clean the valve cover 1018 and the middle cover, preventing bacterial growth.

[0102] As an alternative implementation, in an embodiment not shown in the accompanying drawings, the connection between the valve cover 1018 and the middle cover may also be a threaded connection or an interference fit, etc.

[0103] In one embodiment, such as Figure 8 As shown, the diameter of the third air outlet 10161 is d3, where 4mm≤d3≤8mm.

[0104] When the diameter of the third air outlet 10161 is within the above range, it can avoid excessive noise transmission, and it will not cause slow steam output due to the third air outlet 10161 being too small, resulting in excessive pressure due to untimely pressure release in the food crushing device, or blockage of the third air outlet 10161 during the water discharge process due to the surface tension of water.

[0105] In one embodiment, d3 = 6 mm.

[0106] In one embodiment, the third air outlet 10161 is a circular hole, and d3 is the diameter of the third air outlet 10161.

[0107] As an alternative implementation, in an embodiment not shown in the accompanying drawings, the third air outlet 10161 may also be square, triangular, or elliptical, etc., in which case d3 is the equivalent diameter of the third air outlet 10161.

[0108] In one embodiment, the valve body 101 further includes a retaining rib 1019.

[0109] The surrounding rib 1019 is located inside the valve cavity 1011 and is connected to the top wall of the valve cavity 1011. The surrounding rib 1019 is arranged around the edge of the first air outlet 1012.

[0110] The retaining rib 1019 can increase the number of reflections of noise waves in the valve cavity 1011 while ensuring normal steam outflow, thereby reducing noise consumption in the valve cavity 1011 and achieving a noise reduction effect.

[0111] According to an embodiment of the present invention, another aspect provides a food crushing device, including a cup body and a cup lid 2.

[0112] The cup lid 2 is placed on the cup body, and the cup body is provided with the steam valve provided in the first aspect of this utility model.

[0113] The food crushing device of the second aspect of this utility model includes or uses the steam valve of the first aspect of this utility model, and therefore has the beneficial effect that the steam generated by the food can be discharged outward through the second air outlet 1013, the valve chamber 1011 and the second air outlet 1013 of the steam valve in sequence. The water flow in the steam valve can flow smoothly downward under the guidance of the guide slope 1015, thereby smoothly flowing into the second air outlet 1013, reducing the turbulence and disturbance of the water flow, helping to improve the drainage efficiency, and avoiding noise and vibration of the steam valve caused by turbulence. It also prevents the steam valve from loosening due to vibration, helps to extend the service life of the steam valve, and thus extends the service life of the food crushing device.

[0114] In one embodiment, the cup lid 2 is provided with an installation port 201, the steam valve is located in the installation port 201, and the food crushing device also includes a sealing ring 3.

[0115] The sealing ring 3 is sandwiched between the steam valve and the inner wall of the mounting port 201.

[0116] After sealing ring 3 is formed, it can tightly fit the outer wall of steam valve and the inner wall of mounting port 201 through its own elasticity, fill the tiny gap between the two, prevent steam from seeping out from the mating surface, absorb assembly stress, and reduce vibration and impact.

[0117] In one embodiment, the inner wall of the mounting port 201 is provided with a first snap-fit ​​protrusion 2011, and the outer periphery of the sealing ring 3 is provided with a second snap-fit ​​protrusion 301. The second snap-fit ​​protrusion 301 can pass through the inner periphery of the first snap-fit ​​protrusion 2011 and abut against the first snap-fit ​​protrusion 2011.

[0118] With this configuration, the first snap-fit ​​protrusion 2011 and the second snap-fit ​​protrusion 301 can cooperate with each other to fasten and fix the steam valve on the mounting port 201, thereby achieving a tight fixation of the steam valve, improving the reliability of the steam valve fixation, and preventing the sealing ring 3 from wearing and deforming after long-term use, which could cause steam leakage or loosening of the steam valve.

[0119] In one embodiment, the sealing ring 3 may be made of silicone.

[0120] In a preferred embodiment, the sealing ring 3 is a silicone sleeve with a Shore A hardness of 50-60.

[0121] As an alternative implementation, the sealing ring 3 may also be made of materials such as rubber or thermoplastic elastomer.

[0122] In one embodiment, the food crushing device is a high-speed blender, but the food crushing device of this application is not limited to this.

[0123] In embodiments not shown in other accompanying drawings, the food shredding device may also be a blender or a juicer, etc.

[0124] In summary, the steam valve of the first aspect and the food crushing device of the present invention can solve the problem in the related art that the water flowing back into the steam valve easily forms turbulence on the bottom wall of the valve cavity 1011, which in turn causes noise and even causes the steam valve to vibrate, resulting in the steam valve becoming loose and shortening its service life.

[0125] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope of protection claimed by the present invention.
