Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing machine. Background Technology

[0002] In existing food processors, installing a vent plug on the lid ensures good ventilation during operation, balances the internal and external air pressure, and improves safety. Traditional vent plugs use a straight-through structure. While this structure effectively ensures ventilation speed and quickly maintains pressure balance, it also increases exhaust and grinding noise, significantly amplifying the machine's operating noise. In today's world, where users increasingly value quality of life, excessive noise greatly impacts the user experience. Furthermore, due to the high steam temperature, steam rises rapidly and directly during operation, posing a significant risk of burns.

[0003] To reduce exhaust noise, the applicant previously designed a vent plug with outwardly protruding spiral ribs on its sidewall. These spiral ribs abut against the wall of the cup lid mounting hole to form a spiral exhaust channel. Compared to a straight-through exhaust, this allows steam to spiral out from bottom to top, extending the exhaust path and reducing exhaust noise. Simultaneously, during the crushing process, the crushing noise generated when the blade collides with the material needs to be transmitted through the spiral exhaust channel, further reducing crushing noise. However, while the existing vent plug allows steam and crushing noise to be discharged along the spiral exhaust channel, which reduces noise to some extent, the outlet of the spiral exhaust channel still generates some noise. Further improvement in exhaust noise reduction is needed. Furthermore, the steam discharged from the existing vent plug is high-temperature and fast-moving, posing a significant safety risk of burns to users. Utility Model Content

[0004] This utility model provides a food processing machine that, while addressing the safety risk of burns to users due to the rapid steam emission of existing vent plugs, also solves the technical problem of how to further reduce the overall operating noise of the machine.

[0005] The technical solution adopted in this utility model is as follows:

[0006] This utility model provides a food processing machine, including a cup body, a cup lid, and a vent plug. The cup lid has a vent channel. The vent plug includes a plug body inserted into the vent channel and a top cover fixed to the top of the plug body. The side wall of the plug body has a first spiral rib protruding from it. The first spiral rib abuts against the inner side wall of the vent channel to form a first spiral channel. The first spiral channel communicates with the inner cavity of the cup body. The top of the plug body and the top cover form a second spiral channel communicating with the outside. The second spiral channel includes a gas collecting chamber located at the center of the top cover. The first spiral channel communicates with the gas collecting chamber.

[0007] In the food processing machine provided by this utility model, the vent plug includes a plug body inserted into a venting channel and a top cover fixed to the top of the plug body. A first spiral rib is provided on the side wall of the plug body. The first spiral rib abuts against the inner side wall of the venting channel to form a first spiral channel. The first spiral channel is connected to the inner cavity of the cup body. Therefore, during processing, the hot steam and crushing noise in the cup body can be discharged upward through the first spiral channel. Furthermore, since the top of the plug body and the top cover form a second spiral channel connected to the outside, the second spiral channel includes a gas collecting chamber located in the center of the top cover. The first spiral channel is connected to the gas collecting chamber. Therefore, after being buffered by the first spiral channel, the steam and noise are not directly discharged to the outside, but continue to enter the second spiral channel through the gas collecting chamber in the center of the cup cover, and then discharged to the outside. Therefore, the noise and steam propagation path needs to undergo axial primary noise reduction and primary buffering through the first spiral channel from bottom to top. Subsequently, under the transition of the gas collection chamber, secondary noise reduction and secondary buffering are carried out radially outward along the second spiral channel. Through the second spiral channel, the outward propagation path of noise and steam is extended without increasing the height of the plug body. The steam emission speed is buffered, and cooling is achieved during the emission process. Therefore, it avoids the vent plug from tilting during installation, ensures the stable installation of the vent plug, and eliminates the need to deepen the vent channel to facilitate the cleaning of the cup lid. At the same time, it achieves multi-stage noise reduction and steam buffering effects, reduces the overall operating noise of the machine, reduces the risk of steam burns to users, and improves the safety of use.

[0008] In a preferred embodiment, a first surrounding rib is provided at the top of the plug, and a second surrounding rib is provided at the center of the top cover. The first surrounding rib and the second surrounding rib are interference-fitted to form the gas collecting cavity.

[0009] By interlocking the first and second ribs to form the air collection cavity, a foundation is provided for the enclosure of the second spiral channel. At the same time, the interlocking of the first and second ribs also achieves a fixed connection between the plug and the top cover, eliminating the need for additional fixing steps and structures, thus simplifying the structure of the breathable plug.

[0010] In a preferred embodiment, the top cover is further provided with a second spiral rib connected to the second surrounding rib. The second spiral rib spirals outward around the outer periphery of the second surrounding rib, and the second surrounding rib has a notch, so that the second surrounding rib and the second spiral rib together define the second spiral channel.

[0011] By incorporating a second spiral rib that spirals outward from the second surrounding rib and wraps around its outer circumference, the top cover area is spirally divided. A notch is provided in the second surrounding rib, allowing the second surrounding rib and the second spiral rib to jointly define the second spiral channel. This allows noise to be guided further along the second surrounding rib and the second spiral rib, and then discharged through the second spiral channel, radially extending the exhaust path and reducing noise and steam velocity. The notch ensures reliable communication between the gas collecting chamber and the spiral cavity defined by the second spiral rib. While ensuring reliable interference fit between the top cover and the stopper, steam is smoothly discharged through the second spiral channel, reducing steam emission velocity and temperature, maintaining pressure balance inside and outside the cup, and improving safety during use.

[0012] In a preferred embodiment, a plurality of mating ribs are arranged circumferentially on the outer side of the first surrounding rib, the mating ribs are interference-fitted with the inner side of the second surrounding rib, and an air gap is formed between adjacent mating ribs. The second surrounding rib has a notch, and the notch communicates with the air gap.

[0013] By arranging multiple mating ribs circumferentially at intervals on the outer side of the first rib, and the mating ribs interlocking with the inner side of the second rib, the mating area and friction of the first and second ribs are reduced, making the insertion and installation of the plug and the top cover easier. At the same time, an air passage gap is formed between adjacent mating ribs, and a notch is opened in the second rib, which communicates with the air passage gap. The air passage gap and the notch are used to connect the air collection chamber and the spiral cavity defined by the second spiral rib, forming a complete second spiral channel, so as to achieve a smooth air exhaust effect from the cup to the outside.

[0014] In a preferred embodiment, the outer peripheral surface of the first rib is in interference fit with the inner peripheral surface of the second rib, the first rib has a connecting hole, and the second rib has a notch, the notch being connected to the connecting hole.

[0015] The notch connects to the connecting hole, connecting the gas collecting chamber and the spiral cavity defined by the second spiral rib, forming a complete second spiral channel and enabling smooth exhaust from the cup to the outside. The outer circumferential surface of the first rib and the inner circumferential surface of the second rib are press-fitted together, making the fixation more reliable, preventing the top cover from detaching from the plug, and ensuring structural stability.

[0016] In a preferred embodiment, the top surface of the plug extends to abut against the inner wall of the venting channel, and a second rib is provided at the center of the top cover. The second rib is bonded and fixed to the edge of the top surface of the plug to enclose and form the air collecting cavity.

[0017] In a preferred embodiment, a groove is provided at the top of the plug body, and the groove and the top cover enclose the gas collecting cavity. The first spiral rib extends to the outer wall of the groove, and a through hole is provided radially on the side wall of the groove so that the gas collecting cavity communicates with the first spiral channel.

[0018] By setting a recessed groove at the top of the plug, the recessed groove forms part of the gas collection chamber, resulting in a compact structure that helps reduce the height of the plug. The first spiral rib extends to the outer wall of the recessed groove, making the plug structure compact. At the same time, the side wall of the recessed groove is provided with a through hole in the radial direction, allowing the gas collection chamber to communicate with the first spiral channel. When noise is transmitted upward from the cup body, it first flows along the first spiral channel on the outer periphery, and then enters the gas collection chamber radially through the through hole. It is then spirally discharged to the outside in the radial direction from the second spiral channel. This not only avoids increasing the height of the plug and preventing the plug from protruding too much relative to the cup lid, thus making the structure unstable, but also extends the noise propagation path and reduces noise.

[0019] In a preferred embodiment, the top end of the plug body is provided with an isolation portion that abuts against the inner wall of the venting channel to isolate the gas collecting chamber from the first spiral channel, and the isolation portion is provided with a through hole along the axial direction so that the gas collecting chamber communicates with the first spiral channel.

[0020] By setting an isolation section that abuts against the inner wall of the ventilation channel to isolate the air collection chamber from the first spiral channel, and by setting an axial through hole, noise and steam can be transmitted outward along a specific path, thus ensuring air pressure balance and improving noise reduction effect.

[0021] In a preferred embodiment, the bottom of the plug is hollow to form an air intake chamber that connects the inner cavity of the cup with the first spiral channel.

[0022] By setting an air inlet chamber at the bottom of the stopper, the steam needs to pass through the air inlet chamber for buffering before entering the first spiral channel from the cup body. The noise is buffered in the air inlet chamber, which prolongs the noise transmission path and reduces the noise.

[0023] In a preferred embodiment, the bottom of the plug body is provided with a groove with an opening at the lower end, and the vent plug also includes a bottom cover sealed at the bottom end of the plug body. The bottom cover and the groove enclose the air inlet cavity to form the air inlet cavity. The air inlet cavity has an inlet and an outlet to communicate with the inner cavity of the cup body and the first spiral channel. The inlet and the outlet are both located on the side wall of the air inlet cavity.

[0024] The vent plug also includes a bottom cap sealed at the bottom of the plug body. The bottom cap and the groove of the plug body enclose an air inlet cavity, facilitating independent processing of the plug body and the bottom cap, as well as the formation of the air inlet cavity. Both the inlet and outlet are located on the side wall of the air inlet cavity. Therefore, after noise and steam rise from inside the cup, they need to enter the air inlet cavity from the side inlet, creating a bend in the noise path and lengthening it. The outlet is located on the side wall of the air inlet cavity, achieving direct communication between the air inlet cavity and the first spiral channel, guiding the noise along a specific route to the outside, thus reducing noise.

[0025] In a preferred embodiment, the top cover is provided with a second surrounding rib that encloses and forms the air collecting cavity, and a second spiral rib that extends outward from the second surrounding rib. The second spiral rib extends to connect with the cover side wall of the top cover, and an air outlet is opened on the cover side wall to connect the second spiral channel with the outside.

[0026] By setting a second surrounding rib and a second spiral rib on the top cover, and making the second spiral rib extend to the side wall of the top cover, the spiral channel defined by the second spiral rib extends to the side wall of the cover and connects to the outside through the air outlet, the top cover is maximized and the length of the second spiral channel is maximized under the limited volume of the top cover.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0043] like Figure 1 As shown, in one embodiment, this utility model provides a food processing machine, including a cup body 20, a cup lid 30, and a vent plug 10. The cup lid 30 is provided with a venting channel 31, and the vent plug 10 includes a plug body 11 inserted into the venting channel and a top cover 12 fixed to the top of the plug body 11. Figure 2 , 3 As shown, the side wall of the plug 11 is provided with a first spiral rib 14. The first spiral rib 14 abuts against the inner side wall of the venting channel 31 to form a first spiral channel 101. The first spiral channel 101 communicates with the inner cavity of the cup body 20. The top of the plug 11 and the top cover 12 form a second spiral channel 102 that communicates with the outside. The second spiral channel 102 includes an air collecting chamber 1021 located at the center of the top cover 12. The first spiral channel 101 communicates with the air collecting chamber 1021.

[0044] It should be noted that this utility model does not limit the specific form of the food processing machine. For example, it can be a food processing machine that does not require hand washing, including a main unit and a crushing component fixedly or detachably mounted on the main unit. The crushing component includes the aforementioned cup body 20, cup lid 30, vent plug 10, and a crushing device (such as a crushing blade or moving grinding head) located inside the cup body 20, and a motor for driving the crushing device located below the cup body 20. Of course, the food processing machine can also be a high-speed blender, including a main unit that supports the cup body 20, with the cup body 20 detachably mounted on the main unit.

[0045] In the food processing machine provided by this utility model, the vent plug 10 includes a plug body 11 inserted into the vent channel and a top cover 12 fixed to the top of the plug body 11. A first spiral rib 14 is provided on the side wall of the plug body 11. The first spiral rib 14 abuts against the inner side wall of the vent channel to form a first spiral channel 101. The first spiral channel 101 communicates with the inner cavity of the cup body 20. Therefore, during the processing, the hot steam and crushing noise in the cup body 20 can be discharged upward from the cup body 20 through the first spiral channel 101. Furthermore, since the top of the plug body 11 and the top cover 12 form a second spiral channel 102 that communicates with the outside, the second spiral channel 102 includes a gas collecting chamber 1021 located in the center of the top cover 12. The first spiral channel 101 communicates with the gas collecting chamber 1021. Therefore, after the steam and noise are reduced by the first spiral channel 101, they are not directly discharged to the outside, but continue to enter the second spiral channel 102 through the gas collecting chamber 1021 in the center of the cup cover 30, and then discharged to the outside. Therefore, the noise and steam propagation path needs to undergo axial primary noise reduction through the first spiral channel 101 from bottom to top. Subsequently, under the transition of the gas collecting chamber 1021, secondary noise reduction and buffering are carried out radially outward along the second spiral channel 102. The second spiral channel 102 extends the outward propagation path of noise and steam without increasing the height of the plug body 11, buffering the steam emission speed and achieving cooling during the emission process. Therefore, it avoids the vent plug from tilting during installation, ensuring the stable installation of the vent plug, and also eliminates the need to deepen the vent channel to facilitate cleaning of the cup lid. At the same time, it achieves multi-level noise reduction and steam buffering effects, reducing the overall operating noise of the machine, reducing the risk of steam burns to users, and improving the safety of use.

[0046] This utility model does not limit the specific structure of the breathable plug 10, for example:

[0047] Implementation Example 1, such as Figure 1-5 As shown, the top of the plug body 11 is provided with a first surrounding rib 15, and the center of the top cover 12 is provided with a second surrounding rib 16. The first surrounding rib 15 and the second surrounding rib 16 are interlocked to form an air collecting cavity 1021.

[0048] By interlocking the first surrounding rib 15 and the second surrounding rib 16 to form an air collecting cavity 1021, a foundation is provided for the enclosure of the second spiral channel 102. At the same time, the interlocking of the first surrounding rib 15 and the second surrounding rib 16 also achieves a fixed connection between the plug body 11 and the top cover 12, without the need for additional fixing steps and structures, thus simplifying the structure of the vent plug 10.

[0049] Preferably, such as Figure 2As shown, the top cover 12 is also provided with a second spiral rib 17 connected to the second surrounding rib 16. The second spiral rib 17 spirals outward from the second surrounding rib 16 and surrounds the outer periphery of the second surrounding rib 16. The second surrounding rib 16 has a notch 161, so that the second surrounding rib 16 and the second spiral rib 17 together define the second spiral channel 102. That is, the second spiral channel 102 includes a gas collecting chamber 1021 and a spiral chamber 1022 that are connected.

[0050] By setting a second spiral rib 17, which spirals outward from the second surrounding rib 16 and wraps around the outer periphery of the second surrounding rib 16, the area of ​​the top cover 12 is spirally divided. A notch 161 is provided in the second surrounding rib 16, so that the second surrounding rib 16 and the second spiral rib 17 together define the second spiral channel 102. This allows noise to be further guided along the second surrounding rib 16 and the second spiral rib 17, and discharged through the second spiral channel 102, thus extending the exhaust path radially and reducing noise. The notch 161 allows the gas collecting chamber 1021 to form a reliable connection with the spiral cavity 1022 defined by the second spiral rib 17. While ensuring that the top cover 12 and the plug body 11 are reliably interference-fitted, steam is smoothly discharged through the second spiral channel 102, ensuring the balance of air pressure inside and outside the cup body 20.

[0051] Since the first surrounding rib 15 and the second surrounding rib 16 are interference-fitted, in order to achieve the connection between the gas collecting cavity 1021 and the spiral cavity 1022, specifically, as follows: Figure 2 As shown, multiple mating ribs 18 are arranged circumferentially on the outer side of the first surrounding rib 15. The mating ribs 18 are press-fitted with the inner side of the second surrounding rib 16, forming an air passage gap between adjacent mating ribs 18. The second surrounding rib 16 has a notch 161, which communicates with the air passage gap. Based on this, the top of the first surrounding rib 15 can be made to not contact the cover body to form a gap, and the air collecting cavity 1021 can communicate with the spiral cavity 1022 through this gap and the notch 161; or, the top of the first surrounding rib 15 abuts against the top cover 12, the first surrounding rib 15 has a connecting hole 151, and the notch 161 communicates with the connecting hole 151.

[0052] Of course, in order to improve the axial positioning of the plug and the top cover, preferably, the first rib 15 abuts against the top cover or the second rib 16 abuts against the top of the plug.

[0053] By arranging multiple mating ribs 18 circumferentially at intervals on the outer side of the first surrounding rib 15, and the mating ribs 18 and the inner side of the second surrounding rib 16 with an interference fit, the mating area and friction of the first surrounding rib 15 and the second surrounding rib 16 are reduced, making the insertion and installation of the plug body 11 and the top cover 12 easier. At the same time, an air passage gap is formed between adjacent mating ribs 18, and the second surrounding rib 16 has a notch 161 that communicates with the air passage gap. The air passage gap and the notch 161 are used to connect the air collecting chamber 1021 and the spiral chamber 1022 defined by the second spiral rib 17, forming a complete second spiral channel 102, so as to achieve a smooth exhaust effect from the cup body 20 to the outside.

[0054] In other implementation examples, optionally, the outer peripheral surface of the first rib 15 is made to fit with the inner peripheral surface of the second rib 16, the first rib 15 has a connecting hole 151, and the second rib 16 has a notch 161, with the notch 161 corresponding to and connected to the connecting hole 151. With this configuration, while ensuring reliable axial positioning of the first rib 15 and the top cover 12 by abutting, the connection between the air collecting chamber 1021 and the spiral chamber 1022 is still achieved.

[0055] The notch 161 connects with the connecting hole 151, thus connecting the gas collecting chamber 1021 and the spiral cavity 1022 defined by the second spiral rib 17, forming a complete second spiral channel 102, achieving smooth exhaust from the cup body 20 to the outside. The outer circumferential surface of the first rib 15 and the inner circumferential surface of the second rib 16 are press-fitted together, making the fixation more reliable and preventing the top cover 12 from detaching from the plug body 11, thus ensuring structural stability.

[0056] In addition, such as Figure 3 , 4 As shown, in this embodiment, a groove 111 is provided at the top of the plug 11. The groove 111 and the top cover 12 enclose a gas collecting cavity 1021. The first spiral rib 14 extends to the outer wall of the groove 111. A through hole 113 is provided radially on the side wall of the groove 111 so that the gas collecting cavity 1021 communicates with the first spiral channel 101. In this embodiment, the first surrounding rib 15 extends upward from the opening of the groove 111.

[0057] Of course, in practice, this embodiment can also omit the recess 111 and instead provide a through hole in the first rib 15 to connect the air collecting chamber 1021 with the first spiral channel 101. Additionally, when the top of the plug 11 is provided with the recess 111, noise can be deflected and transmitted by isolating the recess from the air intake chamber.

[0058] By setting a recessed groove 111 at the top of the plug body 11, the recessed groove 111 forms part of the gas collecting cavity 1021, resulting in a compact structure that helps reduce the height of the plug body 11. The first spiral rib 14 extends to the outer wall of the recessed groove 111, making the plug body 11 compact. At the same time, a through hole 113 is provided radially on the side wall of the recessed groove 111, allowing the gas collecting cavity 1021 to communicate with the first spiral channel 101. When noise is transmitted upward from the cup body 20, it first flows along the outer periphery of the first spiral channel 101, and then enters the gas collecting cavity 1021 radially through the through hole 113. It is then spirally discharged to the outside in the radial direction from the second spiral channel 102. This not only avoids increasing the height of the plug body 11 and preventing the plug body 11 from protruding too much relative to the cup lid 30 and causing structural instability, but also extends the noise propagation path and reduces noise.

[0059] like Figure 4 , 5 As shown, more preferably, in this embodiment, the bottom of the plug 11 is hollow, forming an air intake chamber 103 that connects the inner cavity of the cup 20 with the first spiral channel 101. Specifically, as... Figure 5 As shown, the bottom of the plug body 11 is provided with a groove 112 with an opening at the lower end. The vent plug 10 also includes a bottom cover 13 encapsulated at the bottom end of the plug body 11. The bottom cover 13 and the groove 112 enclose each other to form an air inlet chamber 103. The air inlet chamber 103 has an inlet and an outlet to connect the inner cavity of the cup body 20 with the first spiral channel 101. The inlet and outlet are both located on the side wall of the air inlet chamber 103.

[0060] By providing an air inlet chamber 103 at the bottom of the plug body 11, steam needs to pass through the air inlet chamber 103 for buffering before entering the first spiral channel 101 from the cup body 20. Noise is buffered within the air inlet chamber 103, extending the noise transmission path and reducing noise. The vent plug 10 also includes a bottom cover 13 encapsulated at the bottom end of the plug body 11. The bottom cover 13 and the groove 112 of the plug body 11 enclose the air inlet chamber 103, facilitating independent processing of the plug body 11 and the bottom cover 13, as well as the enclosed formation of the air inlet chamber 103. With both the inlet and outlet located on the side wall of the air inlet chamber 103, noise and steam in the cup body 20, after being transmitted upwards, need to enter the air inlet chamber 103 from the side inlet, creating a bend in the noise path and extending the noise path. The outlet is located on the side wall of the air inlet chamber 103, achieving direct communication between the air inlet chamber 103 and the first spiral channel 101, guiding noise along a specific route to the outside and reducing noise.

[0061] like Figure 2 As shown, in this embodiment, the second spiral rib 17 extends to connect with the side wall of the top cover 12, and an air vent 121 is opened on the side wall of the cover to connect the second spiral channel 102 with the outside.

[0062] By providing a second surrounding rib 16 and a second spiral rib 17 on the top cover 12, and extending the second spiral rib 17 to the cover side wall of the top cover 12, the spiral channel defined by the second spiral rib 17 extends to the cover side wall and connects to the outside through the air outlet, thereby maximizing the utilization of the top cover 12 and maximizing the length of the second spiral channel 102 under the limited volume of the top cover 12.

[0063] It is understandable that, in addition to the above-mentioned arrangement, the second spiral channel 102 can also be connected to the outside by a vent through the edge of the top wall of the top cover 12, and the second spiral channel 102 can be connected to the outside through the vent.

[0064] Implementation Example 2, such as Figure 6 , 7 As shown in Figure 8, the main difference between this embodiment and embodiment 1 is the formation method of the gas collecting cavity 1021 and the fixing method of the top cover 12 and the plug 11.

[0065] In this embodiment, the top of the plug 11 has an isolation portion that abuts against the inner wall of the venting channel to isolate the gas collecting chamber from the first spiral channel. Specifically, the isolation portion is an isolation wall that expands outward from the top of the plug. The cover and the upper surface of the isolation portion enclose the gas collecting chamber 1021. The isolation portion has a through hole along the axial direction so that the gas collecting chamber communicates with the first spiral channel. A second rib 16 is provided at the center of the top cover 12. The second rib 16 is bonded and fixed to the top edge of the plug 11 to enclose the gas collecting chamber 1021. For example, it can be bonded with glue.
