Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology for household appliances, specifically to a silent valve structure and a food processing device for reducing noise during steam release. Background Technology

[0002] With people's pursuit of a healthy diet, kitchen appliances such as high-speed blenders and soy milk makers, which integrate food processing and cooking functions, are becoming increasingly popular. These products use high-speed rotating blades to crush and blend ingredients, and with the addition of a heating function, they can easily make a variety of delicious drinks such as soy milk, rice porridge, and thick soups, making them very popular with families.

[0003] During operation, the machine needs to heat the contents inside the cavity to cook food, inevitably generating a large amount of steam. Currently, to safely release this steam and prevent contents from overflowing, products typically have vents or steam valves. However, to prevent heat loss too quickly and maintain cooking efficiency, the steam outlet diameter is usually designed to be small. This design physically restricts steam flow; when high-pressure steam rapidly passes through the narrow channel, it causes significant whistling and vibration, resulting in unpleasant noise and affecting the user experience.

[0004] Therefore, there is an urgent need to propose a silent valve structure and a food processing device for reducing noise during steam release in order to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the problems in related technologies, this utility model proposes a silent valve structure and a food processing device for reducing noise during steam release.

[0006] This utility model is implemented as follows:

[0007] A silent valve structure for reducing noise during steam release includes a valve body, which includes an upper opening, a silent cavity, and a lower opening; the bottom surface of the silent cavity is concave upward or downward to form a first reversing part, and the top surface of the silent cavity is concave upward or downward to form a second reversing part.

[0008] The first deflection section has an opening on its peripheral side, which is the lower opening; the second deflection section has an opening on its peripheral side, which is the upper opening.

[0009] The valve body is installed on the upper surface of the heating container, and the lower opening is located in the inner cavity of the heating container; the upper opening is directly or indirectly exposed to the environment; a steam release channel is formed between the lower opening, the silent cavity and the upper opening, and steam enters the silent cavity from the lower opening and is released into the environment from the upper opening.

[0010] "Environment" refers to the surrounding environment of the equipment containing the heating container. By incorporating upper and lower side openings, steam cannot be directly ejected vertically upwards, effectively disrupting its flow path. Two deflector sections obstruct vertical steam release, increasing flow resistance, while the side openings reduce steam velocity, thereby lowering noise generated by steam discharge. After the pressure inside the heating container increases, the steam spirals upwards and is released within the silent valve.

[0011] Furthermore, the valve body is recessed vertically upward from the bottom outer surface into the silent cavity to form the first deflection part; the cross-section of the first deflection part is a circular ring structure; at least one oblique hole is provided on the side wall of the first deflection part to form the lower opening; the orientation of the oblique hole forms an angle with the radial direction of the circular ring structure.

[0012] By setting the lower opening as an angled hole, the steam ejection forms a rotating spiral vortex in the silencing cavity. Its centrifugal force avoids disorderly congestion of airflow in the silencing cavity, and significantly improves the steam release efficiency and smooth flow while ensuring low noise.

[0013] Furthermore, at least two of the lower openings are circumferentially symmetrically distributed on the annular structure.

[0014] Furthermore, the valve body is recessed vertically downward from the inner surface of the top into the silent cavity to form the second deflection section.

[0015] Furthermore, the first and second reversing parts located within the silencing cavity are both centrally positioned and directly opposite each other, forming a non-connected blank area in the middle.

[0016] Steam is injected into the outer periphery of the first deflector from the lower opening and rotates in a spiral. It gradually spreads upward in the blank area until it flows out from the outer periphery of the second deflector and is released into the upper opening.

[0017] Furthermore, the valve body includes an upper structural component and a lower structural component that can be detachably connected;

[0018] The upper structural member is in the shape of a cover, and the center of the upper structural member has a second reversing portion that is concave upward or concave downward;

[0019] The lower structural member is cup-shaped, with an opening at the top and a first reversing portion that is concave upwards or downwards at the center of the bottom;

[0020] When connected, the upper opening of the lower structural member covers the area of ​​the second deflector in the upper structural member, and the upper and lower structural members surround each other to form the silent cavity.

[0021] By designing a split structure, the detachable and maintainable nature of the silent valve is improved, making it easier to clean after use.

[0022] Furthermore, the lower structural component is made of silicone.

[0023] It also includes a fixing kit; the fixing kit is cup-shaped with an opening at the top and a connecting port at the bottom, the periphery of which is a platform; a first threaded protrusion is provided along the outer side wall of the fixing kit;

[0024] The lower surface of the upper structural member has an annular boss; the annular boss is located on the outer periphery of the second reversing part; a second threaded protrusion is provided along the inner sidewall of the annular boss;

[0025] During connection, the fixing kit is fitted around the outer periphery of the lower structural member, and the bottom of the lower structural member abuts against the surface of the platform; the first threaded protrusion and the second threaded protrusion cooperate to make the lower structural member and the upper structural member abut tightly.

[0026] Silicone material is easier to clean and maintain hygiene, but this structural component is not convenient to connect with rigid structures. Therefore, a fixing kit is used to connect and fix the upper and lower structural components.

[0027] Furthermore, the fixing kit protrudes upward along the edge of the connecting opening to form a first protrusion; the bottom of the lower structural member protrudes downward to form a second annular protrusion; the second protrusion is located on the outer periphery of the first deflecting part;

[0028] After connection, the second protrusion fits around the outer periphery of the first protrusion, fixing the lower structural member to the center of the fixing kit; the radial dimension of the first protrusion is greater than the radial dimension of the recess of the first deflector.

[0029] This utility model provides a food processing device that uses a silent valve structure for reducing noise during steam release, as described above. The food processing device includes a shell and a top cover. The upper part of the shell has an opening for connecting with the top cover. Inside the shell, there is a cup, a heating module, and a support.

[0030] The cup body is the heating container; the heating module is attached to the bottom outer surface of the cup body;

[0031] The bracket is fixed to the bottom of the outer shell, and the cup body is fixed above the bracket; a motor is fixed inside the bracket, and the motor has an upwardly extending, rotatable output shaft; the output shaft extends into the interior of the cup body, and its end is connected to a stirring blade.

[0032] Specifically, the heating module includes a heat spreader and heating elements attached to the surface of the heat spreader; the heat spreader is attached to the bottom of the cup body.

[0033] Furthermore, the upper surface of the cover has an opening and protrudes downward along the edge of the opening to form a connecting portion;

[0034] A groove is provided around the circumference of the valve body; a sealing ring is fitted onto the groove.

[0035] During connection, the valve body is embedded into the connecting part, and the sealing ring and the circumferential inner wall of the connecting part are sealed and fitted together.

[0036] Furthermore, the food processing device also includes an outer cover that surrounds the outer periphery of the outer shell and covers the cup area;

[0037] The valve body has several protrusions evenly distributed circumferentially on its outer periphery;

[0038] The top of the outer cover has a connection port, and along the inner edge of the connection port are a number of L-shaped buckles that are raised and evenly distributed in the circumference; the L-shaped buckles include a horizontal protrusion and a vertical protrusion extending downward from one end of the horizontal protrusion.

[0039] During connection, the valve body is inserted into the connection port and rotated so that the protrusion is positioned below the horizontal protrusion and stops on one side of the vertical protrusion; the protrusion and the buckle cooperate one by one.

[0040] Furthermore, a flange is provided around the body of the valve body; the flange is located above the protrusion; after connection, the flange covers the connection port and abuts against the top outer surface of the outer periphery.

[0041] The beneficial effects are as follows:

[0042] This invention provides a silent valve structure and food processing device for reducing noise during steam release. By setting upper and lower openings with lateral openings, steam cannot be directly ejected vertically upwards, effectively disrupting the steam flow path. Two deflecting sections obstruct vertical steam release and increase flow resistance, while the lateral openings reduce steam velocity, thereby reducing noise generated by steam emission. This effectively avoids the high-speed jet steam and whistling sound generated by the straight-through small openings found in existing technologies. Attached Figure Description

[0064] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0065] like Figures 1 to 10 As shown, this utility model provides a food processing device, specifically a high-speed blender. In other embodiments, it can also be a soymilk maker, a food processor, a blender, etc. The high-speed blender in this embodiment includes a shell 1 and a top cover 2. The upper part of the shell 1 is open for connecting with the top cover 2. The shell 1 contains a cup body 3, a heating module 6, and a support 4.

[0066] The heating module 6 is attached to the bottom outer surface of the cup body 3; specifically, the heating module 6 includes a heat spreader and a heating element attached to the surface of the heat spreader; the heat spreader and the bottom of the cup body 3 are attached to each other.

[0067] The bracket 4 is fixed to the bottom of the outer shell 1, and the cup body 3 is fixed above the bracket 4; a motor 5 is fixed inside the bracket 4, and the motor 5 has an upwardly extending, rotatable output shaft; the output shaft extends into the interior of the cup body 3, and the end is connected to a stirring blade.

[0068] The blender in this embodiment is equipped with a silent valve structure for reducing noise during steam release, including a valve body 7.

[0069] The valve body 7 includes an upper opening, a silent cavity 73, and a lower opening 712. Specifically, in this embodiment, the valve body 7 includes an upper structural member 72 and a lower structural member 71 that can be detachably connected.

[0070] The upper structural member 72 is cap-shaped, with a recessed second deflector portion 721 in the center; the peripheral side of the second deflector portion 721 has two symmetrically arranged openings, which are the upper openings. The upper structural member 72 is a rigid structure, such as being made of plastic.

[0071] The lower structural member 71 is cup-shaped with an opening at the top and a concave first deflection portion 711 at the center of the bottom. The peripheral side of the first deflection portion 711 has four oblique holes arranged symmetrically in a circle, which are the lower openings 712. The cross-section of the first deflection portion 711 is a ring-shaped structure. The orientation of the oblique holes forms an angle with the radial direction of the ring-shaped structure.

[0072] When connected, the upper opening of the lower structural member 71 covers the area of ​​the second deflector 721 in the upper structural member 72, and the upper structural member 72 and the lower structural member 71 enclose each other, forming a silent cavity 73 inside. The first deflector 711 and the second deflector 721 located in the silent cavity 73 are both centrally located and directly opposite each other, forming a blank area between them that is not connected to each other.

[0073] By adopting a split structure, the disassembly and maintenance of the silent valve are improved, facilitating cleaning after use. By designing the lower opening 712 as an angled orifice, a rotating spiral vortex is formed within the silent cavity 73 when steam is ejected. This centrifugal force prevents disorderly congestion of the airflow within the silent cavity 73, significantly improving steam release efficiency and flow smoothness while maintaining low noise. Steam is injected into the outer periphery of the first deflecting section 711 through the lower opening 712 and rotates spirally, gradually spreading upwards in the blank area until it flows upwards from the outer periphery of the second deflecting section 721 and is released through the upper opening.

[0074] In this embodiment, the lower structural member 71 is made of silicone, which is a flexible material and is not convenient to connect with a rigid structure; therefore, a fixing kit 74 is required to connect and fix the upper and lower structural members 71.

[0075] Specifically, the fixing kit 74 is cup-shaped with an opening at the top and a connecting port 741 at the bottom. The periphery of the connecting port 741 is a platform 742. A first threaded protrusion 743 is provided along the outer side wall of the fixing kit 74. The lower surface of the upper structural member 72 has an annular boss. The annular boss is located on the outer periphery of the second deflecting part 721. A second threaded protrusion 724 is provided along the inner side wall of the annular boss.

[0076] For positioning and fixing, the fixing kit 74 protrudes upward along the edge of the connecting port 741 to form a first protrusion 744; the bottom of the lower structural member 71 protrudes downward to form a ring-shaped second protrusion 713; the second protrusion 713 is located on the outer periphery of the first deflection part 711.

[0077] During connection, the fixing kit 74 is fitted onto the outer periphery of the lower structural member 71, and the bottom of the lower structural member 71 abuts against the surface of the platform 742. At this time, the second protrusion 713 is fitted onto the outer periphery of the first protrusion 744, fixing the lower structural member 71 to the center of the fixing kit 74. The radial dimension of the first protrusion 744 is larger than the radial dimension of the recess of the first deflecting part 711. The first threaded protrusion 743 and the second threaded protrusion 724 cooperate to ensure that the lower structural member 71 and the upper structural member 72 are tightly abutted.

[0078] The soundproof cavity 73, made of silicone, is easier to clean and maintain hygiene.

[0079] The valve body 7 is installed on the upper surface of the heating container, and the lower opening 712 is located in the inner cavity of the heating container, which is also the aforementioned cup body 3; the upper opening is exposed to the environment.

[0080] Specifically, in this embodiment, the upper surface of the cover 2 has an opening and protrudes downward along the edge of the opening to form a connecting portion 21; a groove 745 is provided around the outer circumference of the valve body 7, that is, around the outer circumference of the fixing kit 74; a sealing ring 8 is fitted onto the groove 745; during connection, the valve body 7 is inserted into the connecting portion 21, and the sealing ring 8 and the circumferential inner wall of the connecting portion 21 are sealed together. At this time, the lower opening 712 of the valve body 7 is located in the inner cavity of the cup body 3. The opening of the cover 2 is sealed by the sealing ring 8 and the valve body 7, and a steam release channel is formed between the lower opening 712, the silent cavity 73 and the upper opening. Steam enters the silent cavity 73 laterally from the lower opening 712 and is released into the environment laterally from the upper opening.

[0081] "Environment" refers to the surrounding environment of the equipment with the heating container. By setting the upper and lower openings 712 with side openings, the steam cannot rush straight upwards, effectively disrupting the steam flow path. The two deflecting parts block the vertical release of steam, increasing flow resistance, and the side openings reduce the steam flow velocity, thereby reducing the noise generated by steam discharge. After the gas pressure inside the heating container increases, the steam spirals upwards and is released within the silent valve.

[0082] To further enhance the quiet operation of the blender, an outer cover 9 is also provided around the outer casing 1 in this embodiment. Since the noise of the blender mainly originates from the inner cavity of the cup 3, such as the collision noise generated during food crushing and blending, and the noise from steam, the outer cover 9 in this embodiment essentially covers the area of ​​the cup 3. Therefore, the outer cover 9 also includes a silent valve structure.

[0083] In this embodiment, the outer periphery of the valve body 7, that is, the outer periphery of the fixing kit 74, is provided with a plurality of protrusions 746 evenly distributed in the circumferential direction; the top of the outer cover 9 has a connection port 91, and along the inner edge of the connection port 91, there are a plurality of L-shaped buckles 92 that are raised and evenly distributed in the circumferential direction; the L-shaped buckles 92 include a transverse protrusion 921 and a vertical protrusion 922 extending downward from one end of the transverse protrusion 921.

[0084] During connection, the valve body 7 is inserted into the connection port 91 and rotated so that the protrusion 746 is limited to the lower part of the horizontal protrusion 921 and stops on the side of the vertical protrusion 922; the protrusion 746 and the buckle 92 cooperate one by one.

[0085] In this embodiment, a flange 747 is provided around the outer periphery of the valve body 7, that is, around the outer periphery of the fixing kit 74; the flange 747 is located above the protrusion 746; after connection, the flange 747 covers the connection port 91 and abuts against the top outer surface of the outer periphery.

[0086] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
