A cup assembly for a food processor

Abstract

This utility model relates to the technical field of household appliance components, specifically a cup assembly for a food processor. A sealing element is tightly fitted to the outer wall of the insertion portion on the cup lid. The sealing element includes a sealing rib extending radially along the cup body to abut against the inner wall of the cup. The sealing rib surrounds the outside of the pouring hole, and its upper end extends to the supporting surface, thus forming a pouring channel between the pouring hole and the spout, and isolating the pouring channel from the interlayer space. Using this food processor cup assembly effectively solves the problem in existing food processors where, when a user pours the slurry, the liquid flowing from the pouring hole easily flows circumferentially along the outer wall of the cup lid insertion portion, accumulating and remaining in the interlayer between the cup lid and the cup body. When the user opens the cup lid, the residue in the interlayer is easily thrown onto the table or floor, causing cleaning difficulties.

Description

Technical Field

[0001] This utility model relates to the field of household appliance components, and in particular to a cup assembly for a food processing machine. Background Technology

[0002] Existing heated food processors, such as soy milk makers and blenders, generally employ a relatively sealed design for safety reasons during the pulping process, such as in case of accidental spillage during crushing or heating. A common approach is to have a feeding hole in the center of the lid (for feeding ingredients or venting during pulping), a ring-shaped insertion part at the bottom of the lid, and insert the insertion part into the cup body. A sealing ring is then placed on the outer wall of the insertion part. The sealing ring engages with the inner wall of the cup body to achieve a relative seal between the cup body and the lid.

[0003] Of course, the above structure also has certain drawbacks. After each batch of liquid beverage is made, the user needs to open the lid to pour out the liquid. Since the lid is equipped with a sealing ring for sealing with the inner wall of the cup, the sealing ring will rub against the inner wall of the cup every time the lid is removed, making it difficult to remove the lid. Therefore, it is very troublesome for the user to operate. Based on this, the above structure cannot allow the user to pour out the liquid without opening the lid.

[0004] To address the aforementioned issues, Chinese utility model patent CN205612351U discloses a cup lid assembly and a blender. This assembly features a juice outlet (multiple juice / pouring holes) on the insertion part of the cup lid (inner lid) corresponding to the spout. During beverage preparation, hot steam can be expelled from the cup through the juice outlets. Simultaneously, the beverage can be poured out from the spout through the juice outlets without removing the lid, enhancing ease of use. Following this prior art, some existing technologies have proposed a solution of setting a single large-diameter drain hole in the insertion part, which can increase the juice flow rate to some extent.

[0005] However, the above-mentioned improvements still have problems. This is because there is a space between the lid and the cup body, and the flow path between the pouring hole and the spout is not circumferentially restricted. When the user pours the beverage without removing the lid, the beverage may glide too far, causing the liquid to flow out quickly, or the cup body may sway from side to side due to the user's wrist movements. The beverage flowing out of the pouring hole can easily flow along the outer wall of the insert and into the space, causing the beverage to accumulate and remain in the space. When the user needs to clean the food processor, removing the lid will also bring out the residue in the space, which can easily cause the residue to be thrown onto the table and floor, causing cleaning trouble for the user. Moreover, there are more stains left on the lid, making it more difficult to clean. Utility Model Content

[0006] The purpose of this utility model is to provide a cup body component for a food processor, in order to solve the problem that when a user pours the slurry, the slurry flowing from the pouring hole easily flows circumferentially along the outer wall of the cup lid insertion part, and then accumulates and remains in the interlayer between the cup lid and the cup body. When the user opens the cup lid, the residue left in the interlayer is easily thrown onto the table or the ground, causing cleaning trouble for the user.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a cup body assembly for a food processing machine, comprising a cup body with a spout and a cup lid mounted on the cup body. The cup body and the cup lid together form a pulping chamber. The lower end of the cup lid has an annular insertion part that inserts into the cup body. The outer wall of the insertion part has an annular sealing ring. The cup lid is sealed to the inner wall of the cup body through the sealing ring and is located above the sealing ring. The insertion part has a through-hole for pouring pulp, which is radially opposite to the spout and located in the insertion part. Above, the cup lid is provided with an annular supporting surface that rests on the rim of the cup body and is located between the supporting surface and the sealing ring. An annular interlayer space is formed between the cup lid and the cup body. The characteristic is that: the outer wall of the insertion part is closely fitted with a sealing member. The sealing member includes a sealing rib extending radially along the cup body to abut against the inner wall of the cup body. The sealing rib surrounds the outside of the pouring hole, and the upper end of the sealing rib extends to the supporting surface, so that the sealing rib surrounds the pouring hole and the spout to form a pouring channel and isolates the pouring channel from the interlayer space.

[0008] Furthermore, the sealing element includes a sealing body that is tightly attached to the outer wall of the insertion part, and a slurry outlet hole that is aligned with the slurry outlet hole is provided through the sealing body. The sealing rib is integrally formed on the sealing body and surrounds the outside of the slurry outlet hole.

[0009] Furthermore, the sealing body is annular, and the sealing element is fitted tightly against the outer wall of the insertion part through the sealing body.

[0010] Furthermore, the sealing body is provided with a connecting part extending into the grouting hole and interfering with the inner wall of the grouting hole on the side facing the grouting hole. The sealing element is fixed to the grouting hole by the tight fit between the connecting part and the grouting hole, and the grout outlet hole is provided through the connecting part.

[0011] Alternatively, the sealing body has an annular groove on the side facing the grout outlet, and the sealing element is tightly fitted to the grout outlet through the groove, with the grout outlet located inside the groove.

[0012] Furthermore, above the grouting hole, the supporting surface is provided with an upwardly recessed positioning cavity, and the upper end of the sealing body is provided with a sealing part that is inserted into the positioning cavity and closes the opening of the positioning cavity. The sealing element is fixed to the grouting hole by the interference fit between the sealing part and the positioning cavity, and the upper end of the sealing rib extends to connect with the sealing part, and the grouting channel is formed by the sealing rib and the sealing part.

[0013] Furthermore, a buffer barrier is provided inside the pouring hole to block the pouring hole, and a buffer outlet is formed on the upper side of the pouring hole and the buffer barrier, which connects the pouring channel to the pulping chamber.

[0014] Furthermore, the upper end of the slurry discharge hole and the upper end of the buffer enclosure both extend laterally, and the buffer slurry outlet is formed as a transverse strip-shaped opening.

[0015] Alternatively, the lower part of the buffer enclosure is provided with a through return hole, which connects the slurry pouring channel to the slurry preparation chamber.

[0016] Furthermore, the sealing member has a connecting part extending into and cooperating with the grouting hole on the side facing the grouting hole. The sealing member is fixed to the grouting hole by the cooperation of the connecting part and the grouting hole. The buffer barrier is set on the connecting part extending into the grouting hole, and the buffer grout outlet is formed between the connecting part and the buffer barrier.

[0017] Furthermore, the connection between the buffer enclosure and the seal is integrally formed;

[0018] Alternatively, the connecting part is provided with a slot, and the sealing element is held in place at the pouring hole through the slot;

[0019] Alternatively, a support rib is provided at the buffer outlet to connect the connecting part to the buffer enclosure, and the support rib divides the buffer outlet into multiple sub-outlets.

[0020] Alternatively, a buffer cavity is formed on the inner side of the connection portion of the seal, and the buffer cavity connects the buffer outlet to the pouring channel.

[0021] Furthermore, above the sealing ring, the insertion part is also provided with a connecting hole that connects the pulping chamber to the interlayer space.

[0022] Furthermore, the inner wall of the cup is provided with an inwardly protruding locking block, the outer wall of the insertion part is provided with a locking groove, the cup lid is fixed to the cup body by the cooperation of the locking block and the locking groove, and the connecting hole is provided in the locking groove.

[0023] Furthermore, the cup lid includes an inner cup lid and an outer cup lid. The insertion part is formed at the lower part of the inner cup lid, the supporting surface is formed at the lower end of the outer cup lid, and an annular sound insulation cavity is provided between the inner cup lid and the outer cup lid. The sound insulation cavity is connected to the interlayer space, and a sealing block is sealed inside the sound insulation cavity. The upper end of the sealing rib extends to connect with the sealing block, and the pouring channel is formed by the sealing rib and the sealing block.

[0024] Furthermore, the sound insulation cavity is provided with two partition ribs, which are located on both sides above the grout pouring hole, and a positioning cavity is formed between the two partition ribs. The sealing block is inserted into the positioning cavity and closes the opening of the positioning cavity. The sealing ribs and the sealing block together isolate the grout pouring channel from the sound insulation cavity and the interlayer space.

[0025] Alternatively, the sealing block is inserted into the sound insulation cavity in a ring shape and seals the opening of the sound insulation cavity. The sealing block isolates the sound insulation cavity from the interlayer space, and the sound insulation cavity, the interlayer space and the pouring channel are not interconnected.

[0026] Alternatively, the sealing block includes a guide portion inserted into the sound insulation cavity and a sealing portion located at the lower end of the guide portion, wherein the radial thickness of the guide portion is less than the radial thickness of the sealing portion;

[0027] Alternatively, the sealant and the sealing block are integrally formed.

[0028] Furthermore, the sealing element and the sealing ring are integrally formed;

[0029] Alternatively, the seal may be detachably connected to the insertion portion;

[0030] Alternatively, the seal and the insertion part can be integrally injection molded.

[0031] For existing food processors, a sealing ring is installed on the insertion part of the lid to seal against the inner wall of the cup body, forming a relatively sealed pulping chamber. A through-hole is also provided on the insertion part of the lid, above the sealing ring, allowing users to pour out the liquid beverage from the pulping chamber without opening the lid. However, a ring-shaped space exists between the lid and the cup body. When pouring out the beverage through the through-hole, some of the beverage flows along the sides of the through-hole into this space, accumulating and remaining there. If the user pours too quickly or shakes the cup during pouring, even more residue accumulates in this space, leading to food waste. More seriously, when the user removes the lid for cleaning, the residue is carried out and splashed onto the table and floor, causing cleaning difficulties. Furthermore, the outer wall of the lid insertion part also accumulates a significant amount of residue, making cleaning even more challenging.

[0032] Based on this, in order to solve the above-mentioned technical problems, this utility model provides a cup body assembly for a food processing machine. A sealing element is tightly installed on the outer wall of the insertion part of the cup lid, and the sealing element includes a sealing rib extending radially along the cup body to abut against the inner wall of the cup body. The sealing rib is arranged around the outside of the pouring hole of the cup lid, and the upper end of the sealing rib extends to the overlapping surface of the cup lid, so that the sealing rib surrounds the pouring hole and the spout to form a pouring channel. Since the sealing rib isolates the pouring channel from the interlayer space, the pouring channel is sealed relative to the interlayer space. When the user tilts the cup body to pour out the liquid beverage, due to the sealing and blocking effect of the sealing rib, the liquid beverage flowing out of the pouring hole will not flow into the interlayer space along the circumference of the insertion part. Compared with the prior art, this effectively solves the problem of liquid beverage accumulation and residue in the interlayer space caused by pouring, which causes the user to throw the residue onto the table and the ground when removing the cup lid, making it difficult for the user to clean. At the same time, there is very little residue on the cup lid, and the cup lid is cleaner and more convenient to clean.

[0033] Furthermore, during the pouring process, users may pour too forcefully or tilt the cup too quickly, causing the scalding hot beverage to gush out rapidly, posing a risk of burns. To address this, the food processor of this invention features an upward-extending buffer barrier inside the pouring hole to at least partially block it, with a buffer outlet formed between the pouring hole and the upper edge of the buffer barrier. Even if the cup tilts too quickly or is poured too forcefully, the buffer barrier can block most of the beverage, while a small portion can flow through the buffer outlet along the pouring channel and out through the spout, preventing a large outflow of scalding hot beverage. Compared to existing technologies, the buffer barrier significantly reduces the risk of burns during pouring. Simultaneously, when making cold drinks or tea, the buffer barrier can also prevent solid substances such as incompletely crushed fruit residue or tea leaves from escaping, making it easier for users to pour and drink. Furthermore, in order to prevent unpoured beverage slurry from accumulating in the pouring channel, the cup assembly of the food processing machine of this utility model can also be provided with a return hole at the bottom of the buffer enclosure, so that the residual slurry in the pouring channel can flow back into the cup body through the return hole.

[0034] In addition, for the cup body assembly of the food processing machine of this utility model, when the cup lid is set as a double-layer structure with noise reduction and sound insulation, a sealing block can be inserted into the annular sound insulation cavity to block the lower opening of the sound insulation cavity, and the upper end of the sealing rib extends to connect with the sealing block. The sealing block and the sealing rib together surround the pouring hole in the circumferential direction, so that the pouring channel is formed by the sealing rib and the sealing block. Compared with the prior art, the food processing machine of this utility model can reduce the noise of the cup lid, and also prevent the liquid beverage from entering the annular sound insulation cavity and the interlayer space during the pouring process, which would make the subsequent cleaning of the cup lid more difficult.

[0055] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings. It should be noted that while many specific details are set forth in the following description to provide a full understanding of this utility model, it can also be implemented in other ways different from those described herein. Therefore, the scope of protection of this utility model is not limited to the specific embodiments disclosed below.

[0056] The main purpose of this invention is to address the issue that, when food processors require pouring slurry without opening the lid, existing food processors, even with pouring holes in the lid insertion part, still suffer from the problem of slurry flowing out of the holes and circumferentially along the outer wall of the lid insertion part when the user pours, leaving residue in the annular space between the lid insertion part and the cup body. When the user opens the lid, this residue is easily splashed onto the table or floor, causing inconvenience for cleaning. This patent aims to solve the aforementioned technical problem through improvements.

[0057] The specific implementation scheme of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0058] Implementation 1:

[0059] like Figures 1 to 8 The diagram shown is a structural schematic of the first embodiment of this utility model. A food processing machine that allows for pouring liquid without opening the lid includes a main unit 1 and a detachable cup assembly mounted on the main unit 1. The cup assembly includes a cup body 2 with a spout 21 and a lid 3 fitted onto the cup body 2. The cup body 2 and lid 3 together form a pulping chamber 20. The main unit 1 contains a motor (not shown in the diagram), and the cup body 2 contains a stirring device (not marked in the diagram). The motor drives the stirring device to rotate via a coupling between the main unit 1 and the cup assembly, thereby processing the ingredients in the pulping chamber 20 to produce a liquid beverage.

[0060] In this embodiment, the lower end of the cup lid 3 is provided with an annular insertion part 32 that inserts into the cup body 2. The outer wall of the insertion part 32 is provided with an annular sealing ring 4. The cup lid 3 is sealed to the inner wall of the cup body 2 through the sealing ring 4 and is located above the sealing ring 4. The insertion part 32 is provided with a through pouring hole 31. The pouring hole 31 is radially opposite to the spout 21 and is located above the insertion part 32. The cup lid 3 is provided with an annular supporting surface 33 that supports the rim of the cup body 2 and is located on the supporting surface 33. Between the sealing ring 4 and the cup lid 3 and the cup body 2, an annular interlayer space 100 is formed. The outer wall of the insertion part 32 is tightly fitted with a sealing member 5. The sealing member 5 includes a sealing rib 51 extending radially along the cup body 2 to abut against the inner wall of the cup body 2. The sealing rib 51 surrounds the outside of the pouring hole 31, and the upper end of the sealing rib 51 extends to the supporting surface 33, so that the sealing rib 51 surrounds the pouring hole 31 and the cup spout 21 to form a pouring channel 10, and isolates the pouring channel 10 from the interlayer space 100.

[0061] In this embodiment, the sealing element 5 further includes a sealing body 52 that is tightly attached to the outer wall of the insertion part 32. A slurry outlet hole 50, aligned with the slurry outlet hole 31, is provided through the sealing body 52. ​​A sealing rib 51 is integrally formed on the sealing body 52 and surrounds the outside of the slurry outlet hole 50. The sealing body 52 has a connecting part 53 extending into the inside of the slurry outlet hole 31 on the side facing the slurry outlet hole 31. An annular groove 54 is provided on the connecting part 53. The sealing element 5 is engaged with the slurry outlet hole 31 through the groove 54, and the slurry outlet hole 50 is located inside the groove 54 and extends through the connecting part 53.

[0062] Meanwhile, above the grouting hole 31, the supporting surface 33 is provided with an upwardly recessed positioning cavity 330, and the upper end of the sealing body 52 is also provided with a sealing part 55 that is inserted into the positioning cavity 330 and closes the opening of the positioning cavity 330. The upper end of the sealing rib 51 extends to connect with the sealing part 55, and the grouting channel 10 is formed by the sealing rib 51 and the sealing part 55.

[0063] As is well known, existing food processing machines, regardless of whether they have the function of pouring the slurry without opening the lid, will have a sealing ring at the lower end of the lid insertion part to seal against the inner wall of the cup, in order to prevent the slurry from overflowing due to the stirring device agitating the slurry during the slurry making process and the possible accidental overflow of the slurry during heating and cooking. This is a common operating method in the industry.

[0064] Existing technologies for pouring syrup without opening the lid simply involve creating a through-hole above the lid insert and sealing ring. While the syrup can flow out of the spout through this hole, the sealing ring on the insert introduces a new problem that the industry has not yet addressed. The syrup flowing out of the hole easily runs along the circumferential direction of the lid insert, accumulating and remaining in the annular space between the lid insert and the cup body. When the user opens the lid, the syrup or residue remaining in this annular space is easily thrown onto the table or floor, causing inconvenience for cleaning.

[0065] After careful study and analysis, the applicant identified the following main reasons:

[0066] After the slurry passes through the pouring hole, it must first pass through the annular area between the lid insert and the inner wall of the cup before flowing out of the spout. Although the pouring hole and the spout are directly opposite each other, there is no part around the lid insert that can obstruct or restrict the flow of the slurry. If the user accidentally tilts the cup at too large an angle, resulting in an excessive flow of slurry, or if the user's wrist swings from side to side during the pouring process, causing the cup to sway from side to side, the slurry will flow into the annular space between the lid insert and the inner wall of the cup.

[0067] If existing food processors do not have a sealing ring in the insertion part, the slurry flowing into the annular space will naturally flow back into the cup along the inner wall. However, it is precisely this industry-standard "beneficial" sealing ring design that leads to slurry residue remaining in the annular space between the lid insertion part and the cup body under uncertain user operating scenarios. Furthermore, when the user opens the lid, the residual slurry can easily be splashed onto the table or floor, causing inconvenience for the user in cleaning. Those skilled in the art, limited by their preconceived notions of the industry's conventional "beneficial" design, have not realized this problem for users and therefore have not proposed a better solution for pouring slurry without opening the lid.

[0068] This embodiment addresses the aforementioned user concerns by providing a food processor that allows for pouring without opening the lid. A sealing element is tightly fitted to the outer wall of the lid's insertion portion. This sealing element includes a sealing rib extending radially along the cup body to abut against the inner wall of the cup. The sealing rib surrounds the outside of the pouring hole in the lid, with its upper end extending to the overlapping surface of the lid, thus forming a pouring channel between the pouring hole and the spout. Because the sealing rib isolates the pouring channel from the interlayer space, the channel is sealed relative to the interlayer space. When the user tilts the cup to pour the liquid beverage, the sealing rib prevents the liquid beverage flowing from the pouring hole from flowing circumferentially into the interlayer space. Compared to existing technologies, this effectively solves the problem of liquid beverage accumulation and residue in the interlayer space caused by pouring, which leads to residue being thrown onto the table or floor during lid removal, causing cleaning difficulties. Furthermore, there is very little residue on the lid, making cleaning easier and more convenient.

[0069] It should be noted that in this embodiment, the seal is detachably installed on the insertion part of the cup lid. The installation method of the seal at the pouring hole of the insertion part is not limited to the scheme disclosed in this embodiment. For example, in this embodiment, the seal can be tightly fixed to the pouring hole simply by the interference fit between the connecting part and the pouring hole, without needing to provide a groove on the connecting part or an interference fit between the sealing part and the positioning cavity. Of course, the seal can also be tightly fixed to the pouring hole simply by the interference fit between the sealing part and the positioning cavity.

[0070] It should be noted that in this embodiment, the sealing element is tightly attached to the outer wall of the insertion part. This is to prevent the liquid beverage flowing from the pouring hole from entering the gap between the sealing body and the insertion part during pouring. The tight fit of the sealing element also allows the liquid beverage to flow from the pouring hole into the pouring channel and then be poured out through the spout. Of course, for this embodiment, the sealing element may not have a sealing body; instead, it may only have a sealing rib. A sealing element with only a sealing rib can be integrally formed with the insertion part through a secondary injection molding process.

[0071] Additionally, it should be noted that in this embodiment, the positioning cavity is sealed by a sealing part. Preferably, the lower surface of the sealing part is not lower than the supporting surface. The sealing part is generally set to be flush with the supporting surface. However, since the sealing element is generally made of food-grade silicone, during the installation process, the sealing part may be inserted into the inside of the positioning cavity, making the lower surface of the sealing part higher than the supporting surface. In this case, the upper end of the sealing rib also needs to extend into the positioning cavity and connect with the lower surface of the sealing part to prevent the grout from flowing into the interlayer space during pouring.

[0072] It should be noted that the above-described structural changes in this embodiment can also be applied to other embodiments of this utility model. Example 2:

[0073] like Figures 9 to 11 The diagram shown is a structural schematic of the second embodiment of this utility model. In the food processing machine of this embodiment, a motor (not marked in the figure) is provided at the bottom of the cup body 2. The rotating shaft of the motor passes directly through the bottom wall of the cup body 2 and extends into the cup body 2. The end of the rotating shaft is connected to the stirring device (not marked in the figure) and drives the stirring device to rotate.

[0074] In this embodiment, the sealing member 5 includes an annular sealing body 52, and the sealing body 52 is provided with a through-hole 50. The sealing rib 51 surrounds the outside of the through-hole 50, and the upper end of the sealing rib 51 extends to abut against the supporting surface 33 of the cup lid 3. The sealing member 5 is fitted tightly against the outer wall of the insertion part 32 by the sealing body 52, and the through-hole 50 is positioned directly opposite the pouring hole 31 on the cup lid 3.

[0075] Furthermore, in this embodiment, the sealing element 5 and the sealing ring 4 are integrally injection molded.

[0076] In this embodiment, during installation, simply tightening the sealing element onto the outer wall of the insertion part achieves a seal between the lid and the cup body, preventing the slurry from overflowing through the gap between the lid and the cup body during the slurry-making process. Simultaneously, a slurry-pouring channel is formed between the pouring hole and the spout, isolating it from the interlayer space. This prevents slurry from entering the interlayer space when pouring out the slurry, and also makes it more convenient for users to disassemble, clean, and reinstall the sealing element themselves.

[0077] Of course, for the sealing element in this embodiment, it can also be directly fixed to the insertion part of the cup lid at the factory and cannot be disassembled. For example, the top of the sealing element can be clamped to the cup lid and cannot be disassembled, which reduces the trouble of repeated disassembly and installation for users. At the same time, in order to facilitate better alignment between the slurry outlet hole on the sealing element and the slurry pouring hole on the cup lid, a positioning rib can be set around the edge of the slurry pouring hole. During installation, the slurry outlet hole of the sealing element is placed on the outside of the positioning rib, which makes it easier to position the sealing element at the slurry pouring hole.

[0078] Similarly, it should be noted that the above-described structural changes in this embodiment can also be applied to other embodiments of this utility model. Example 3:

[0079] like Figures 12 to 18The diagram shown is a structural schematic of the third embodiment of this utility model. This embodiment is a further improvement based on the first embodiment. The difference between this embodiment and the first embodiment is that: in this embodiment, a tea basket assembly (not marked in the figure) is also provided on the cup lid 3. The cup lid 3 and the tea basket assembly together form a cup lid assembly. The food processing machine of this embodiment can be used to make tea drinks. The user places the tea blocks in the tea basket assembly and seals the tea basket assembly onto the cup lid 3 so that the liquid in the pulping chamber 20 is heated and extracted. During the extraction process, the extraction effect is improved by stirring with a stirring device (not shown in the figure).

[0080] In this embodiment, the cup lid 3 includes an inner cup lid 34 and an outer cup lid 35. The insertion part 32 is formed at the lower part of the inner cup lid 34, and the supporting surface 33 is formed at the lower end of the outer cup lid 35. An annular sound-insulating cavity 36 with an opening at the lower end is provided between the inner cup lid 34 and the outer cup lid 35. The sound-insulating cavity 36 communicates with the interlayer space 100, and a sealing block 6 is sealed inside the sound-insulating cavity 36. The upper end of the sealing rib 51 extends to connect with the sealing block 6. The pouring channel 10 is formed by the sealing rib 51 and the sealing block 6. In this embodiment, the sealing block 6 and the sealing element 5 are integrally formed.

[0081] The sound insulation cavity 36 is provided with two separating ribs 37, which are located on both sides above the grout pouring hole 31, and form a positioning cavity 38 between the two separating ribs 37. The sealing block 6 is inserted into the positioning cavity 38 and seals the opening of the positioning cavity 38. The sealing rib 51 and the sealing block 6 together isolate the grout pouring channel 10 from the sound insulation cavity 36 and the interlayer space 100. The sealing block 6 includes a guide part 61 inserted into the positioning cavity 38 and a blocking part 62 located at the lower end of the guide part 61. The radial thickness of the guide part 61 is smaller than the radial thickness of the blocking part 62, so that the sealing block 6 can be better installed in the positioning cavity 38, and the upper end of the sealing rib 51 extends to connect with the blocking part 62.

[0082] Meanwhile, a buffer barrier 56 is provided inside the pouring hole 31 to block the pouring hole 31, and a buffer outlet 57 is formed on the upper side of the pouring hole 31 and the buffer barrier 56, and the buffer outlet 57 connects the pouring channel 10 and the pulping chamber 20.

[0083] In this embodiment, the buffer barrier 56 is integrally formed on the connecting portion 53 of the sealing member 5. Similar to Embodiment 1, the connecting portion 53 is provided with a slot (not marked in the figure), and the sealing member 5 is held in place at the pouring hole 31 by the slot. Furthermore, in this embodiment, the buffer outlet 57 is formed between the connecting portion 53 and the buffer barrier 56. The sealing member 5 is located inside the connecting portion 53, and the inner walls of the buffer barrier 56 and the connecting portion 53 enclose a buffer cavity 58. The buffer cavity 58 connects the buffer outlet 57 to the pouring channel 10, and the sealing rib 51 and the sealing portion 62 together enclose the pouring channel 10 and the buffer cavity 58 within it. Additionally, the upper ends of the pouring hole 31, the connecting portion 53, and the buffer barrier 56 all extend laterally; therefore, the buffer outlet 57 is formed as a transverse strip-shaped opening. It is located inside the buffer chamber 58, and the bottom of the buffer enclosure 56 is provided with a through return hole 59, which connects the buffer chamber 58 to the pulping chamber 20.

[0084] In addition, in this embodiment, the cup lid 3 is fixed to the cup body 2 by screwing, and an inwardly protruding locking block (not shown in the figure) is provided on the inner wall of the cup body 2. A locking groove 39 is provided on the outer wall of the insertion part 32 and above the sealing ring 4. When the cup lid 3 is screwed onto the cup body 2, the locking block is locked into the locking groove 39, thereby fixing the cup lid 3 to the cup body 2. A through connecting hole 310 is provided in the locking groove 39, which connects the pulping chamber 20 to the interlayer space 100.

[0085] Noise reduction in existing food processing machines has always been a goal pursued by the industry. As the main noise-blocking components during the crushing and mixing operations of food processing machines, the lid and body play a relatively important role. In particular, the double-layer lid or double-layer body structure, through the sound insulation cavity set between the two layers, can effectively block the transmission of noise sources to the outside.

[0086] Although double-layered lids offer noise reduction, most existing food processing machines still use single-layered lids, with virtually no lids featuring a ring-shaped sound-insulating cavity between the two layers. Even in cases where double-layered lids exist, the ring-shaped sound-insulating cavity between the two layers is not exposed. The applicant believes this is likely due to considerations of structural complexity. Firstly, single-layered lids are cheaper to manufacture; secondly, their simpler structure makes them easier to clean, while double-layered lids with exposed openings tend to trap residue, hindering cleaning. Based on this, prior patent applications for non-opening pouring systems generally do not disclose double-layered lid structures with exposed sound-insulating cavities at the bottom. Precisely because these prior applications did not disclose such double-layered lid structures, they almost never considered the new technical problems that applying double-layered lids to non-opening pouring food processing machines would bring, or how to solve these new technical problems.

[0087] To address the noise reduction issue, the inventors of this application designed the cup lid as a double-layer structure consisting of an inner cup lid and an outer cup lid. The insertion part is placed on the inner cup lid. In actual manufacturing, the entire inner cup lid and the insertion part can be integrally molded. An annular sound insulation cavity with an exposed lower opening is formed between the inner cup lid and the outer cup lid. The lower end face of the outer cup lid forms the overlapping surface of the cup lid. During their research, the inventors realized that applying this structure to a food processor that pours liquid without opening the lid created a new problem not previously mentioned in the industry: The area above the insertion part of the inner lid (i.e., the part of the inner lid that does not extend into the cup body) has an annular sound-insulating cavity between it and the outer lid. When pouring liquid without opening the lid, the liquid flows into this annular cavity and circumferentially, resulting in residue of the liquid in both the annular cavity and the interlayer space. Because the sound-insulating cavity and the interlayer space are connected, and the space formed by the connection is relatively large, even more liquid residue accumulates in this connected space during the pouring process. Therefore, subsequent cleaning and rinsing will cause greater inconvenience when users remove the lid for washing.

[0088] In this embodiment of the food processing machine, to solve the aforementioned user concerns, when the cup lid is configured with a double-layer structure for noise reduction and sound insulation, a sealing block is inserted into the annular sound insulation cavity to block the lower opening of the sound insulation cavity. The upper end of the sealing rib extends to connect with the sealing block. The sealing block and the sealing rib together surround the pouring hole in the circumferential direction, so that the pouring channel is formed by the sealing rib and the sealing block. Compared with the prior art, the food processing machine of this embodiment can not only reduce the noise of the cup lid, but also prevent the liquid beverage from entering the annular sound insulation cavity and the interlayer space during the pouring process, thus making subsequent cup lid cleaning more difficult.

[0089] Meanwhile, during the pouring process, users may pour too forcefully or tilt the cup too quickly, causing the scalding hot beverage to gush out rapidly, posing a risk of burns. Therefore, this embodiment of the food processor also proposes an upward-extending buffer barrier inside the pouring hole to at least partially block it, and a buffer outlet is formed between the pouring hole and the upper edge of the buffer barrier. Even if the user tilts the cup too quickly or pours too forcefully, the buffer barrier can block most of the beverage, while a small portion can be poured out through the buffer outlet along the pouring channel and spout, preventing a large amount of scalding hot beverage from gushing out. Compared to existing technologies, the buffer barrier in this embodiment of the food processor significantly reduces the risk of burns during pouring. Furthermore, when making cold drinks or tea, the buffer barrier can also block some solid substances in the beverage, such as incompletely crushed fruit residue or tea leaves, making it easier for users to pour and drink. Furthermore, in order to prevent unpoured beverage slurry from accumulating in the pouring channel and buffer chamber, the food processing machine in this embodiment also has a return hole at the bottom of the buffer enclosure. The residual slurry in the pouring channel and buffer chamber can flow back into the cup through the return hole.

[0090] In addition, in this embodiment, when the user tilts the cup to pour out the liquid beverage from the pulping chamber, since the buffer outlet is smaller than the pouring hole, the pulp will form a sealed chamber after it overflows from the buffer outlet and covers the entire buffer outlet. At this time, there may be an imbalance between the pressure inside the pulping chamber and the outside air pressure. The pressure inside the pulping chamber is lower than the outside atmospheric pressure, which causes the liquid in the pulping chamber to be poured out unsmoothly. To address this issue, in this embodiment, a connecting hole is provided in the engaging groove of the insertion part. The connecting hole connects the pulping chamber with the interlayer space. The cup lid rests on the rim of the cup body via a supporting surface. The supporting surface and the rim are not in a tightly sealed state. Therefore, the interlayer space is actually open to the outside atmosphere. Thus, the connecting hole allows the pulping chamber to be connected to the outside atmosphere, achieving a balance between the pulping chamber and the outside atmosphere. Based on this, the connecting hole plays a role in balancing the air pressure between the pulping chamber and the outside, allowing the pulp beverage in the pulping chamber to be poured out more smoothly.

[0091] In this embodiment, although the locking block on the inner wall of the cup engages with the locking groove when the lid is closed, a gap still exists between the locking block and the connecting hole. This means the locking block cannot completely seal the connecting hole. During the pulping process, when the pulp in the pulping chamber tumbles and agitates, the locking block can, to some extent, prevent splashing of the pulp, thus preventing a large amount from entering the interlayer space. Of course, the connecting hole used to balance the air pressure inside and outside the pulping chamber is not limited to the locking groove in this embodiment; it can also be located in other parts of the insertion part. Even when the cup lid is not equipped with the tea basket assembly, a vent hole on the top wall of the cup lid can also help balance the air pressure. However, the inventors have found that for food processing machines that do not open the lid for pouring, the top wall of the cup lid should ideally be a sealed structure. During the pouring process, if the user tilts the lid too quickly, some of the hot pulp may overflow from the vent hole at the top of the cup lid, potentially scalding the user.

[0092] It should be noted that in this embodiment, mating grooves can also be provided on both sides of the sealing block to mate with the two partition ribs provided in the sound insulation cavity, so that the sealing block can be better positioned in the positioning cavity defined by the two partition ribs. Of course, the sealing block in this embodiment can also be a separate structure from the sealing element. For example, the sealing block is inserted into the sound insulation cavity in a ring shape and closes the opening of the sound insulation cavity. The upper end of the sealing rib on the sealing element extends to abut against the lower end face of the sealing block, and the sealing block isolates the sound insulation cavity from the interlayer space. The sound insulation cavity, the interlayer space and the grouting channel are also not interconnected.

[0093] In this embodiment, the sealing block, sealing element, and sealing ring can be integrally formed or are separate structures.

[0094] like Figure 19 As shown, another variation of the sealing component in this embodiment differs from the sealing component in that a support rib 512 is provided at the buffer outlet 57 to connect the connecting part 53 and the buffer enclosure 56, and the support rib 512 divides the buffer outlet 57 into multiple sub-outlets.

[0095] As mentioned earlier, the buffer barrier acts as a buffer to prevent the slurry from overflowing too quickly and scalding the user. However, during pouring, the buffer barrier absorbs the impact energy of the slurry, and there is a risk of deformation towards the buffer chamber. This is because the seals are generally made of food-grade silicone, which has good elasticity. Therefore, when the buffer barrier deforms, the area of ​​the slurry outlet increases accordingly, but the problem of excessively rapid and large amounts of slurry flowing from the spout and scalding the consumer still exists. To prevent deformation of the buffer barrier, a [further measures can be taken]. Figure 19As shown, a supporting rib connecting the buffer barrier and the connecting part is provided at the buffer outlet. This not only provides support for the buffer barrier but also reduces the area of ​​the buffer outlet. Of course, the buffer barrier is not limited to the structure of this embodiment. The buffer barrier can also be integrally formed or separately installed on the inner wall of the insertion part, as long as it can block the pouring hole and form a buffer outlet with the upper side of the pouring hole, thus having the function of buffering and blocking the slurry.

[0096] Furthermore, it should be noted that the food processor of this invention can be used to make beverages such as soy milk that require grinding ingredients; therefore, the stirring device can be a grinding blade. Of course, the food processor of this invention can also be used to make beverages that do not require grinding ingredients, such as milk tea. A tea basket is placed inside the cup, and tea pieces are placed in the basket. The stirring device is used to drive the liquid flow to rotate and disperse and extract the tea beverage in the basket. Moreover, the structural form of the food processor of this invention is not limited to the solution provided in this embodiment. The food processor of this invention can also be a bottom-mounted food processor where the motor is directly fixed to the cup body, forming an integral part of the cup body; or it can be a top-mounted food processor where the motor is installed inside the cup lid, and the rotating shaft driven by the motor extends directly into the cup body and is connected to the stirring device.

Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
