Description

Technical Field

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

[0002] Food processors have gradually become standard kitchen appliances in recent years due to their ability to process food into more delicate, easier to digest and absorb, and more beneficial to human health. When the food processor is running at high speed, the centrifugal force caused by the high-speed rotation of the turntable increases the air pressure inside the food processor. The air pressure inside the food processor is greater than the atmospheric pressure, thus forming a pressure difference with the air inlet, realizing the food processor's stirring function. When the food processor stops working, the air pressure inside the food processor will drop rapidly. At the same time, a certain amount of air is sucked in by the air inlet. At this time, the air pressure inside the food processor is lower than the atmospheric pressure. The air pressure inside the food processor forms a pressure difference with the air inlet, realizing the food processor's suction function. Therefore, when the food processor is working, it is necessary to provide a micro-pressure exhaust structure on the upper cover structure of the food processor.

[0003] The existing micro-pressure exhaust structure mainly uses a micro-pressure exhaust valve to realize the exhaust function inside the food processor. Once food residue blocks the exhaust port or the micro-pressure exhaust valve fails, the exhaust cannot be discharged, the internal air pressure is too high, and it is dangerous.

[0004] For the above problems, no effective solution has been proposed yet. Utility Model Content

The silent cover covers at least part of the cup body and / or at least part of the cover body. The silent cover cover beads are arranged on the silent cover. A soundproof cavity connected to the atmosphere is formed between the silent cover and the cover body. When the auxiliary exhaust device is in the second open state, the gas in the cooking cavity enters the atmosphere through the air holes and the soundproof cavity in turn.

[0012] Furthermore, the micro-pressure valve structure includes: a valve body, a first exhaust channel is formed inside the valve body, a first end of the first exhaust channel is connected to the cooking chamber, and a second end of the first exhaust channel is connected to the atmosphere; an opening and closing member, the opening and closing member is located in the first exhaust channel, the opening and closing member is movably arranged relative to the valve body, and the opening and closing member has a blocking position and at least one avoidance position, wherein, when the opening and closing member is in the blocking position, the opening and closing member blocks the first exhaust channel to put the micro-pressure valve structure in a closed state, and when the opening and closing member is in the avoidance position, the opening and closing member at least partially opens the first exhaust channel to put the micro-pressure valve structure in an open state.

[0035] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0036] A food processor is a multifunctional kitchen appliance that can perform a variety of food processing tasks, including blending, beating, grinding, mincing, and juicing, greatly simplifying food preparation in the kitchen. Food processors include blenders, soymilk makers, juicers, blenders, coffee machines, and more.

[0037] Combine Figures 1 to 3 As shown, according to a specific embodiment of the present application, a food processor is provided.

[0038] Specifically, the food processor includes: a cup body 1, a lid body 2, a silent cover bead 4, a micro-pressure valve structure 5, and an auxiliary exhaust device 100. The cup body 1 has a cooking chamber; the lid body 2 is connected to the cup body 1; the silent cover bead 4 is connected to the lid body 2; the micro-pressure valve structure 5 is disposed on at least one of the silent cover bead 4 and the lid body 2, and has a first closed state that seals the cooking chamber and a first open state that connects the cooking chamber to the atmosphere; the auxiliary exhaust device 100 is disposed on the lid body 2, and has a second closed state that seals the cooking chamber and a second open state that connects the cooking chamber to the atmosphere; the triggering pressure of the first open state of the micro-pressure valve structure 5 is different from the triggering pressure of the second open state of the auxiliary exhaust device 100.

[0039] The technical solution of the present invention is to provide a micro-pressure valve structure 5 on the silent cover bead 4 or the cover body 2. By switching the micro-pressure valve structure 5 between closed and open states, the food processor can increase the pressure inside the container to improve heating efficiency and cooking results. If the micro-pressure valve structure 5 malfunctions and cannot exhaust, resulting in excessive pressure in the cooking chamber, the auxiliary exhaust device 100 can be activated to assist in exhaust, thereby avoiding the danger of excessive pressure in the cooking chamber. This solution further solves the problem in the prior art where exhaust failure caused by food processor malfunction can cause abnormal internal pressure increases, thereby posing a safety hazard.

[0040] Specifically, if Figure 2As shown, when the pressure in the cooking chamber is greater than or equal to a first pressure threshold, the micro-pressure valve structure 5 is in a first open state. When the pressure in the cooking chamber is greater than or equal to a second pressure threshold, the auxiliary exhaust device 100 is in a second open state. The first pressure threshold is less than or equal to the second pressure threshold. If the micro-pressure valve structure 5 malfunctions and cannot exhaust, opening the auxiliary exhaust device 100 can help the micro-pressure valve structure 5 release gas from the cooking chamber, preventing potential dangers caused by excessive internal pressure. For example, the first pressure critical value is set to 1MPA, and the second pressure critical value is set to 2MPA. During the heating process, the pressure in the cooking chamber gradually increases. The cooking chamber is in a micro-pressure environment to speed up the heating efficiency. When the pressure in the cooking chamber reaches 1MPA, the micro-pressure valve structure 5 is in the first open state, and the gas in the cooking chamber flows to the atmosphere for pressure relief. However, after the micro-pressure valve structure 5 fails, the pressure in the cooking chamber gradually increases but the gas cannot be discharged. When the air pressure reaches 2MPA, the auxiliary exhaust device 100 is in the second open state that connects the cooking chamber with the atmosphere. The gas in the cooking chamber can be discharged to the atmosphere through the auxiliary exhaust device 100 for rapid pressure relief, thereby avoiding the danger of excessive pressure in the cooking chamber.

[0041] Further, if Figure 1 As shown, the lid 2 is provided with an air hole connected to the cooking chamber, and the auxiliary exhaust device 100 includes: a ejector pin and a film structure. The ejector pin is connected to the lid 2, with its tip facing the film structure. The film structure is disposed within the air hole, and its size corresponds to the size of the air hole. The film structure is located below the ejector pin and is deformable toward the ejector pin. The film structure has a sealing position for sealing the air hole and a pressure relief position that deforms toward the ejector pin to be punctured by the ejector pin. In the event of an emergency situation where the food processor faces an abnormally high pressure, the auxiliary exhaust device 100 can provide an additional exhaust path by puncturing the film structure through the ejector pin, ensuring the safety of the device and the user.

[0042] When the internal pressure of the food processor is normal, the membrane structure is in a sealed position. When the internal pressure rises to a second pressure threshold due to a malfunction of the micro-pressure valve structure 5, the membrane structure, under the pressure, is in a pressure-relieving position, deforming toward the ejector pin. At this point, the membrane structure is pierced by the ejector pin, and the auxiliary exhaust device 100 enters a second, open state, creating an emergency exhaust passageway for exhausting gas from the cooking chamber to the atmosphere. The membrane structure can be a single-layer or multi-layer structure. Its material must be able to withstand the first pressure threshold without rupture, while also ensuring that it can be easily penetrated or pushed open by the ejector pin when the second pressure threshold is reached, forming a vent.

[0043] In one exemplary embodiment, auxiliary exhaust device 100 includes a pressure relief valve. The lid 2 is provided with an air hole communicating with the cooking chamber. The pressure relief valve is disposed within the air hole and is movable relative to the air hole along a first direction, which is a vertical direction extending from the cooking chamber toward the upper end of the lid 2. When the pressure relief valve moves along the first direction to a target position, auxiliary exhaust device 100 enters a second, open state. As the pressure relief valve moves along the first direction, auxiliary exhaust device 100 gradually opens, discharging gas from the cooking chamber and preventing safety accidents caused by high internal pressure.

[0044] When the food processor is operating normally, the pressure relief valve is in a closed state. When the internal pressure of the food processor rises abnormally due to food blockage, failure of the micro-pressure valve structure 5, etc., the pressure sensing mechanism in the pressure relief valve is activated. Once the pressure exceeds the preset second pressure critical value, the valve will move in the first direction to form an emergency exhaust channel to release the internal pressure. When the internal pressure drops below the second pressure critical value, the pressure relief valve automatically closes under the action of a spring or other reset mechanism and returns to a closed state to ensure the normal operating conditions of the food processor. As an auxiliary exhaust device 100, the pressure relief valve can automatically open to release the internal pressure when the micro-pressure valve structure 5 of the food processor fails, preventing the equipment from having safety accidents due to internal high pressure, thereby providing double safety protection for users.

[0045] Specifically, the pressure relief valve is provided with a first valve section 101 and a second valve section 102 along the first direction, the second valve section 102 is located at the bottom of the first valve section 101, the outer diameter of the second valve section 102 is smaller than the inner diameter of the pore, and the outer diameter of the first valve section 101 is greater than or equal to the inner diameter of the pore, wherein, when the first valve section 101 is located in the pore, the auxiliary exhaust device 100 is located in the second closed state, and when the second valve section 102 moves along the first direction into the pore, the auxiliary exhaust device 100 is located in the second open state.

[0046] like Figure 1 As shown, the auxiliary exhaust device 100 is in the second closed state, the second valve section 102 of the pressure relief valve is located in the cooking chamber, and the first valve section 101 is located in the air hole and partially located above the cover body 2. The outer diameter of the first valve section 101 is greater than or equal to the inner diameter of the air hole, which can ensure that the air hole is completely sealed to prevent gas leakage.

[0047] like Figure 2As shown, auxiliary exhaust device 100 is in its second, open state. If the micro-pressure valve structure 5 malfunctions, gas in the cooking chamber cannot be exhausted, and pressure gradually increases. When the pressure exceeds a second pressure threshold, the second valve section 102 of the pressure relief valve is moved in the first direction into the air hole under the pressure. At this point, first valve section 101 is completely above lid 2. Because the outer diameter of second valve section 102 is smaller than the inner diameter of the air hole, gas in the cooking chamber flows from the air hole to the atmosphere, reducing the pressure in the cooking chamber. The smaller outer diameter of second valve section 102 than the inner diameter of the air hole allows for more sensitive sensing of pressure changes within the food processor. Due to its smaller cross-sectional area, it generates greater thrust at the same pressure, facilitating a rapid response and opening of the pressure relief valve upon reaching the preset opening pressure. The smaller second valve section 102 also prevents food debris or debris from entering the valve, reducing the risk of clogging. The outer diameter of the first valve section 101 is greater than or equal to the inner diameter of the air hole, which helps to control the discharge flow of steam or gas and ensure smooth airflow during the pressure release process. The larger outlet can reduce turbulence and noise during discharge, while accelerating the pressure drop rate. Through the design of different inner diameters of the first valve section 101 and the second valve section 102, the pressure relief valve can respond more sensitively to abnormal increases in internal pressure, while ensuring smooth airflow and minimization of noise during the pressure release process, thereby ensuring equipment safety while also improving user experience.

[0048] Furthermore, the food processor includes a silent cover 3, which is connected to the lid 2 and shields at least a portion of the cup body 1 and / or at least a portion of the lid 2. A silent cover bead 4 is disposed on the silent cover 3, located in the middle of the top of the silent cover 3. A soundproof cavity 6 connected to the atmosphere is formed between the silent cover 3 and the lid 2. The soundproof cavity 6 is divided into two left and right parts by the silent cover bead 4. When the auxiliary exhaust device 100 is in the second open state, the gas in the cooking chamber enters the atmosphere through the air hole and the soundproof cavity 6 in sequence. When the air pressure in the cooking chamber is greater than the second pressure threshold, the second valve section 102 moves along the first direction into the air hole, allowing the gas to enter the soundproof cavity 6 through the air hole and then be discharged from the soundproof cavity 6 to the atmosphere. The soundproof cavity 6 can also further reduce the noise generated when the gas is discharged from the air hole.

[0049] It should be noted that the silent cover bead 4 is composed of two parts: an upper cover bead shell 41 and a lower cover bead shell 42. The lower cover bead shell 42 is connected to the first exhaust channel 52. The upper cover bead shell 41 and the lower cover bead shell 42 can be connected by integral molding or welding to form a non-detachable unit, or they can be connected simply and quickly by snap-fitting. An elastic seal 7 is provided between the silent cover bead 4 and the cover body 2. The elastic seal 7 is a sealing ring. The elastic seal 7 ensures a good seal between the silent cover bead 4 and the cover body 2, preventing steam leakage in the cooking chamber during cooking, and also preventing external impurities such as dust from entering the interior of the device.

[0050] Specifically, the micro-pressure valve structure 5 comprises a valve body 51 and an opening / closing member 53. A first exhaust channel 52 is formed within the valve body 51. The first end of the first exhaust channel 52 communicates with the cooking chamber, and the second end communicates with the atmosphere. The opening / closing member 53 is positioned within the first exhaust channel 52 and is movably disposed relative to the valve body 51. The opening / closing member 53 has a blocking position and at least one escape position. In the blocking position, the opening / closing member 53 blocks the first exhaust channel 52, placing the micro-pressure valve structure 5 in a first closed state. In the escape position, the opening / closing member 53 at least partially opens the first exhaust channel 52, placing the micro-pressure valve structure 5 in a first open state. The automatic switching of the opening / closing member 53 between the blocking and escape positions enables dynamic control of the air pressure in the cooking chamber. Through this switching mechanism, the micro-pressure valve structure 5 can automatically adjust the internal air pressure at different stages of cooking, ensuring efficient and high-quality cooking while avoiding safety hazards.

[0051] The micro-pressure valve structure 5 is positioned in the middle of the silent cover bead 4. A first exhaust channel 52 is used to release excess air pressure within the micro-pressure valve structure 5. Designed to be elongated and inclined at a predetermined angle, it automatically opens and closes under the force of gravity of an opening / closing member 53. The first end of the first exhaust channel 52 communicates with the cooking chamber, allowing steam to enter. During the initial cooking phase, or when the air pressure has not reached the preset value, the opening / closing member 53 is in the blocked position. The opening / closing member 53 (a small ball in this embodiment) uses its own gravity to block the first exhaust channel 52, confining the steam within the cooking chamber and creating a micro-pressure environment.

[0052] During the cooking process, as the temperature in the cooking chamber rises, the steam pressure gradually increases. When the pressure exceeds the closing threshold of the opening and closing member 53, the opening and closing member 53 is lifted up by the steam pressure and pushed open to the avoidance position. At this time, the first exhaust channel 52 is at least partially open, and the micro-pressure valve structure 5 is in the first open state. At this time, the second end of the first exhaust channel 52 is connected to the atmosphere, and excess steam is released into the atmospheric environment, avoiding potential safety hazards caused by excessive internal pressure, such as equipment explosion or food sticking to the bottom. When the pressure drops below the safe level, the opening and closing member 53 naturally falls back and re-seals the first exhaust channel 52, maintaining a micro-pressure environment and improving heating efficiency.

[0053] Specifically, the valve body 51 extends along a second direction, extending vertically from the first end of the first exhaust passage 52 to the second end of the first exhaust passage 52. The projected area of ​​the valve body 51 along this second direction gradually increases. This design employs a tapered, gradually expanding channel structure. This cleverly utilizes a gradual geometric change to improve the efficiency of steam flow and the opening and closing performance of the shutter 53. Specifically, the smaller inlet area precisely controls the steam flow, ensuring that only when internal pressure builds sufficiently to overcome the weight of the shutter 53 will it be pushed and moved relative to the valve body 51, opening the first exhaust passage 52. As steam passes through the first exhaust passage 52, the gradually increasing outlet area provides a smooth and quiet exhaust environment. This not only facilitates rapid steam diffusion and prevents pressure buildup at the outlet, but also ensures stable operation of the shutter 53 and prevents adverse effects caused by sudden airflow changes. This tapered, gradually expanding design effectively balances steam emission control and efficiency, enhancing the safety and user experience of the entire exhaust system.

[0054] Optionally, a bearing portion is formed at the first end of the first exhaust channel 52, and when the opening and closing member 53 abuts the bearing portion, the opening and closing member 53 is located in a blocking position. The bearing portion is a structure that can support the opening and closing member 53, such as a small platform or a raised portion. The function of the bearing portion is to provide a positioning and support point for the opening and closing member 53. When the opening and closing member 53 abuts the bearing portion, the opening and closing member 53 is in a blocking position, effectively closing the first exhaust channel 52, preventing steam from flowing out, and maintaining a micro-pressure environment in the cooking chamber. When the pressure is large enough, the opening and closing member 53 leaves the bearing portion, and the steam is discharged through the first exhaust channel 52. The design of the bearing portion needs to take into account the hardness and wear resistance of the material to withstand the gravity and steam pressure of the opening and closing member 53 while maintaining its stability and reliability.

[0055] Specifically, the valve body 51 is arranged on the silent cover bead 4, and the cover body 2 has a second exhaust channel 21. When the opening and closing member 53 is in the avoidance position, one end of the second exhaust channel 21 is connected to the first exhaust channel 52, and the other end of the second exhaust channel 21 is connected to the cooking chamber, so that the first exhaust channel 52 is connected to the cooking chamber.

[0056] like Figure 2As shown, the lid 2 has a second exhaust channel 21. When the opening / closing member 53 is in the avoidance position, one end of the second exhaust channel 21 communicates with the first exhaust channel 52, and the other end of the second exhaust channel 21 communicates with the cooking chamber, thereby connecting the first exhaust channel 52 with the cooking chamber. The second exhaust channel 21 is larger than the first exhaust channel 52. The first exhaust channel and the opening / closing member 53 are designed to cooperate. The size and weight of the opening / closing member 53 determine the minimum opening size of the channel to ensure that the opening / closing member 53 can be accurately opened when a micro-pressure state is reached. The second exhaust channel 21 does not need to cooperate with the opening / closing member 53 and can be designed to be wider. When the opening / closing member 53 is pushed open, the second exhaust channel 21 communicates with the first exhaust channel 52, allowing a large amount of steam to be quickly discharged, helping to quickly adjust the air pressure in the cooking chamber. At the same time, when the opening / closing member 53 is not opened, the second exhaust channel 21 can serve as a backup exhaust path to ensure safe operation of the device.

[0057] In an exemplary embodiment, the valve body 51 is arranged on the cover body 2, and the silent cover bead 4 is provided with an air flow hole connected to the atmosphere on the side facing the cover body 2. When the opening and closing member 53 is in the avoidance position, the first exhaust channel 52 is connected to the air flow hole, so that the air flow in the cooking chamber passes through the cover body 2 and the silent cover bead 4 in turn and flows into the atmosphere.

[0058] Specifically, the airflow hole is connected to the first exhaust channel 52 through an internal channel, forming an airflow path from the cooking chamber to the atmosphere. When the opening and closing member 53 (such as a small ball) is pushed to the avoidance position due to increased internal pressure, the first exhaust channel 52 is opened, and the airflow hole becomes a pressure release outlet, allowing overpressure gas to be quickly discharged. The combination of the airflow hole and the first exhaust channel 52 forms a complete micro-pressure control system, which not only ensures that the food processor reaches and maintains the required micro-pressure state during cooking, but also quickly releases pressure when the pressure rises abnormally.

[0059] In an alternative embodiment, the auxiliary exhaust device 100 is disposed on the lid 2, and the micro-pressure valve structure 5 is disposed within the silent cover bead 4, with the two being relatively independent. When the air pressure within the food processor rises due to heating, the micro-pressure valve structure 5 is operating normally. However, due to excessive pressure, the auxiliary exhaust device 100 is activated, even if the micro-pressure valve structure 5 is not faulty. In this case, the auxiliary exhaust device 100 and the micro-pressure valve structure 5 can jointly relieve pressure, accelerating the pressure drop within the cooking chamber and sharing the pressure relief pressure of the micro-pressure valve structure 5. For example, during the heating process, when the pressure within the cooking chamber reaches 1 MPa, the micro-pressure valve structure 5 enters the first open state, allowing the gas within the cooking chamber to flow to the atmosphere. When the pressure within the cooking chamber reaches 2 MPa, the pressure within the cooking chamber is excessive and requires rapid pressure relief. At this time, the gas exhaust rate through the micro-pressure valve structure 5 alone is too slow. Therefore, the auxiliary exhaust device 100 is activated, allowing the gas within the cooking chamber to be discharged to the atmosphere through the auxiliary exhaust device 100, reducing the pressure relief pressure of the micro-pressure valve structure 5 and rapidly depressurizing the cooking chamber.

[0060] It should be further explained that the food processor also includes a handle 8 and a power interface 9.

[0061] like Figure 3 As shown, the handle 8 is connected to the cup body 1 and is set on the left side of the cup body 1. The handle 8 is designed in a U-shape and has a non-slip design, allowing users to easily pick up or move the food processor. In particular, when the device needs to be repositioned or cleaned after use, the handle 8 provides a stable grip, enhancing the convenience and safety of operation. During use, the handle 8 can prevent the user from directly contacting hot or live parts, especially after micro-pressure cooking, when high temperatures may remain in the cooking chamber. The handle 8 design ensures that the user will not be burned, improving overall safety.

[0062] Power port 9, located at the bottom of the food processor, is the key point for connecting the food processor to an external power source.
