Description

Technical Field

[0001] The utility model belongs to the technical field of food processing devices, and in particular relates to a food processing machine that is safe to use. Background Art

[0002] At present, the food processors on the market generally include a cup body with a built-in crushing knife and a cup cover on the cup body. In order to balance the internal and external air pressure of the cup body and improve the safety of use, it is usually necessary to set a vent hole on the cup cover for exhaust. There are two main existing exhaust methods:

[0003] One method is to set an air hole in the center of the cup lid. This method has a simple structure, but if the air hole is too large, liquid may splash from the air hole when the crushing knife rotates. If the air hole is too small, the air hole may be blocked and difficult to clean, causing inconvenience to the user. Another method is to set an air hole in the center of the cup lid, install an air plug in the air hole, and set an air channel in the air plug to prevent liquid splashing while achieving ventilation. This method is conducive to preventing liquid from splashing from the air hole, but due to the addition of accessories, the structure becomes complicated and the cost increases. There is a risk of blockage of the air channel and poor ventilation due to missing or improper installation. In addition, dirt and grime are easily hidden inside the air plug, which may not be cleaned thoroughly and is inconvenient to use.

[0004] In addition, both existing exhaust methods cause the middle space of the cup cover to be occupied by the air holes, and it is impossible to install a handle or other structure on the cup cover to facilitate user operation. Generally, a handle needs to be protruded from the edge of the cup cover, which causes the cup cover to become larger in size, the structure is not compact, and the user's operation is inconvenient, which reduces the user experience. Utility Model Content

[0005] The utility model provides a food processing machine which is safe to use. By improving the cup cover structure and optimizing the ventilation mode of the cup cover, the utility model solves the problem that liquid splashing easily occurs on the existing cup cover and solves the problem that the cup cover has a complex structure and is inconvenient to clean.

[0006] The technical solution adopted by the utility model is:

[0007] The utility model provides a food processing machine that is safe to use, comprising a cup body with a built-in crushing knife, a cup cover covering the cup body, and a heating element for heating the cup body, wherein the top wall of the cup cover is provided with an air hole offset relative to the center of the cup cover, the air hole is communicated with the inner cavity of the cup body, the top wall of the cup cover is provided with a connecting plate extending downward along the edge of the air hole and a shielding plate formed by horizontally bending from the bottom end of the connecting plate, and the shielding plate shields the area directly below the air hole.

[0008] The utility model provides a safe food processor, which provides an air hole on the top wall of the cup cover, and the air hole is connected to the inner cavity of the cup body, so that the internal and external air pressures of the cup body are balanced during the operation of the food processor, and the safety of use is improved. The air hole is offset relative to the center of the cup cover, which is conducive to improving the compactness of the overall structure of the cup cover, so as to facilitate the installation of the handle and facilitate the user to open the cover. By providing a connecting plate and a shielding plate formed by horizontal bending from the bottom end of the connecting plate on the top wall of the cup cover, the shielding plate is used to shield the area directly below the air hole. When the heating element is working to boil the slurry in the cup body, the shielding plate can be used to effectively prevent the boiling liquid from splashing upward from the air hole, and reduce the situation where the slurry splashes violently and flies out of the air hole during the operation of the crushing knife. The connecting plate extends downward along the edge of the vent hole, so that a certain distance is spaced between the shielding plate and the top wall of the cup cover, so that the gas in the cup body can be discharged smoothly. At the same time, the dead corners for dirt are reduced. When the user cleans the cup cover, the space between the shielding plate and the cup cover can be directly flushed, which is convenient and thorough to clean and hygienic to use. The connecting plate and the shielding plate cooperate to further reduce the probability of liquid splashing from the vent hole during the rotation of the crushing knife and the boiling of the heating element. Therefore, the utility model realizes smooth ventilation of the cup cover while preventing liquid from splashing, improves the safety of the whole machine, simplifies the structure of the cup cover and reduces the production cost compared to the traditional method of setting a vent plug, and provides users with conveniences such as cleaning and opening the cover during use, which is convenient for users to use and improves the user experience.

[0009] In a preferred embodiment, the two side ends of the connecting plate are connected with enclosures extending along the edges of the shielding plate, and the ends of the enclosures and the ends of the shielding plate form a transverse opening, and the opening is arranged toward the center of the cup body.

[0010] By connecting the aprons to the two side ends of the connecting plate, the aprons extend along the edge of the shielding plate. Therefore, under the joint shielding effect of the aprons and the connecting plate, the vent holes are shielded in multiple directions. Whether it is during the boiling process of the heating element or the rotation process of the crushing knife, the liquid flow to the vent holes can be effectively blocked, thereby improving the flow blocking effect and preventing the vent holes from being blocked. The end of the apron and the end of the shielding plate are used to form a horizontal opening, and the opening is arranged toward the center of the cup body, which can facilitate the smooth and rapid discharge of gas and is safe to use.

[0011] In a preferred embodiment, a partition is further provided on the top wall of the cup cover, and the partition is arranged opposite to the opening to cover the opening.

[0012] A partition is arranged opposite to the opening to block the opening, thereby preventing the slurry from splashing into the opening. Therefore, the partition, the shielding plate and the connecting plate form a multi-layer barrier to prevent the slurry from splashing out of the air vent, thereby effectively solving the problem of slurry splashing.

[0013] In a preferred embodiment, an extension plate connected to the enclosure is provided on the opposite side of the connecting plate, and the extension plate extends downward from the top wall of the cup cover, and the end of the extension plate, the end of the enclosure and the end of the shielding plate form the opening.

[0014] By setting an extension plate, the end of the extension plate, the end of the enclosure plate and the end of the shielding plate form the opening, which is helpful to reduce the open area of ​​the opening, reduce the probability of slurry splashing, and effectively solve the problem of slurry splashing.

[0015] In a preferred embodiment, the partition is arranged to be inclined toward the center of the cup body along the rotation direction of the crushing knife.

[0016] By tilting the partition toward the center of the cup body along the rotation direction of the crushing knife, the partition can be used to block the opening and also to guide the flow toward the center of the cup body, thereby achieving thorough crushing and improving the crushing effect.

[0017] In a preferred embodiment, the connecting plate extends in a ring shape along the circumference of the air vent, and a transverse opening is provided on the connecting plate.

[0018] By extending the connecting plate into a ring shape along the circumference of the air hole and arranging a transverse opening on the connecting plate, an air passage is formed between the opening and the air hole, and the entrance of the air passage is a transversely arranged opening. Compared with the traditional up and down ventilation method, it effectively reduces the splashing and spraying of slurry.

[0019] In a preferred embodiment, a handle is protruding upward from the center of the top wall of the cup cover.

[0020] A handle is protruding upward from the center of the top wall of the cup lid. Compared with the traditional method of protruding the handle on the edge of the cup lid, it can reduce the volume of the cup lid and simplify the structure of the cup lid. At the same time, it avoids interference from structures such as the handle on the cup body when the user grasps the handle, making it easier for the user to lift the lid and improving the user experience.

[0021] In a preferred embodiment, the top wall of the cup cover forms a groove downward, and the handle is protruded in the groove;

[0022] A groove is provided on the top wall of the cup cover and the handle is protruded into the groove. On the premise of ensuring that the user has enough space to grasp the handle, the overall height of the cup cover and the height of the whole machine can be reduced, making it convenient for the user to open the cover and store it.

[0023] In a preferred embodiment, the handle and the cup cover are separately provided and fixedly connected by a fastener, and a rotation-stopping structure is provided between the handle and the cup cover.

[0024] By separating the handle from the cup cover, the shape of the handle can be flexibly selected according to actual needs. The cup cover is formed by a universal mold, which is convenient for mass production and reduces production costs. A rotation-stopping structure is set between the handle and the cup cover to ensure the stability of the matching of the handle and the cup cover, and reliable use.

[0025] In a preferred embodiment, the cup cover also has a side wall extending downward from the edge of the top wall, the side wall extends into the cup body and radially limits the side wall of the cup body, a magnet is fixedly mounted on the side wall, and a detection element cooperating with the magnet is mounted on the outside of the cup body.

[0026] By setting a magnet on the side wall of the cup cover and installing a detection element on the outside of the cup body, the cup cover can be detected in place. If the detection element does not detect the magnet, the whole machine will recognize that the cup cover is not installed in place and stop working, thereby effectively avoiding the danger of slurry splashing. The side wall of the cup cover can not only realize the radial limit of the cup cover and the cup body, but also provide a magnet installation position. There is no need to extend the top wall of the cup cover outward to install the magnet, which reduces the volume of the cup cover, simplifies the structure of the cup cover, and saves production costs.

[0027] In a preferred embodiment, a sealing ring is provided on the side wall of the cup cover, the sealing ring is interference fit with the side wall of the cup body, and the magnet is located above the sealing ring.

[0028] By setting a sealing ring on the cup cover, the matching gap between the cup body and the cup cover is further sealed to prevent the slurry from splashing or overflowing the cup body, which is safe to use. The magnet is set above the sealing ring to avoid the influence of steam on the magnet during processing, so that the magnet and the detection element can be matched reliably to achieve accurate lid closing detection.

[0042] like Figure 1-5 As shown, the utility model provides a safe food processor in Example 1, comprising a cup body 10 with a built-in crushing blade 11, a cup cover 20 covering the cup body 10, a heating element 12 for heating the cup body 10, and a motor 13 fixed to the bottom of the cup body 10 to drive the crushing blade 11. The top wall of the cup cover 20 is provided with an air hole 21 offset relative to the center of the cup cover 20, and the air hole 21 is connected to the inner cavity of the cup body 10, as shown in FIG. Figure 2 As shown, the top wall of the cup cover 20 is provided with a connecting plate 22 extending downward along the edge of the air vent 21 and a shielding plate 23 formed by horizontal bending from the bottom end of the connecting plate 22. The shielding plate 23 shields directly below the air vent 21, that is, the horizontal projection of the air vent 21 falls into the horizontal projection of the shielding plate 23.

[0043] The food processor provided by the utility model is safe to use. By setting the air hole 21 on the top wall of the cup cover 20, the air hole 21 is connected with the inner cavity of the cup body 10, so that the internal and external air pressure of the cup body 10 is balanced during the operation of the food processor, and the safety of use is improved. The air hole 21 is offset relative to the center of the cup cover 20, which is conducive to improving the compactness of the overall structure of the cup cover 20, so as to facilitate the installation of the handle 30 and facilitate the user to open the cover. By setting the connecting plate 22 and the shielding plate 23 formed by the horizontal bending from the bottom end of the connecting plate 22 on the top wall of the cup cover 20, the shielding plate 23 is used to shield the bottom of the air hole 21. When the heating element 12 is working to boil the slurry in the cup body 10, the shielding plate 23 can be used to effectively prevent the boiling liquid from splashing upward from the air hole 21, and reduce the situation that the slurry splashes violently and flies out of the air hole 21 during the operation of the crushing knife 11. The connecting plate 22 extends downward along the edge of the air hole 21, so that a certain distance is spaced between the shielding plate 23 and the top wall of the cup cover 20, so as to facilitate the smooth discharge of gas in the cup body 10. At the same time, the dead corners for dirt are reduced. When the user cleans the cup cover 20, the space between the shielding plate 23 and the cup cover 20 can be directly flushed, which is convenient and thorough to clean and hygienic to use. The connecting plate 22 and the shielding plate 23 cooperate to further reduce the probability of liquid splashing from the air hole 21 during the rotation of the crushing knife 11 and the boiling of the heating element 12. Therefore, the utility model realizes smooth ventilation of the cup cover 20 while preventing liquid from splashing, improves the safety of the whole machine, simplifies the structure of the cup cover 20 and reduces the production cost compared to the traditional method of setting a ventilation plug, and provides users with conveniences such as cleaning and opening the cover during use, which is convenient for users to use and improves the user experience.

[0044] like Figure 3 As shown, preferably, in implementation example 1, the two side ends of the connecting plate 22 are connected with a surrounding plate 24 extending along the edge of the shielding plate 23, and the ends of the surrounding plate 24 and the ends of the shielding plate 23 form a horizontal opening 26, and the opening 26 is set toward the center of the cup body 10.

[0045] As a more preferred embodiment, Figure 3 As shown, a partition 27 is further disposed on the top wall of the cup cover 20 , and the partition 27 is disposed opposite to the opening 26 to cover the opening 26 .

[0046] By connecting the enclosure 24 to the two side ends of the connecting plate 22, the enclosure 24 extends along the edge of the shielding plate 23. Therefore, under the joint shielding effect of the enclosure 24 and the connecting plate 22, the air holes 21 are shielded in multiple directions. Whether it is during the boiling process of the heating element 12 or the rotation process of the crushing knife 11, it can effectively prevent the liquid from splashing toward the air holes 21, thereby improving the flow blocking effect and preventing the air holes 21 from being blocked. The end of the enclosure 24 and the end of the shielding plate 23 are used to form a horizontal opening 26, and the opening 26 is arranged toward the center of the cup body 10, which can facilitate the smooth and rapid discharge of gas and is safe to use.

[0047] It can be understood that the partition 27 is directly opposite to the opening 26, that is, the projection of the opening 26 on the vertical plane falls into the partition 27. Therefore, the partition 27 can be optionally arranged parallel to the vertical plane where the opening 26 is located, or, as shown in FIG. Figure 3 As shown, the partition plate 27 is arranged to be inclined toward the center of the cup body 10 along the rotation direction of the crushing knife 11 .

[0048] By setting the partition 27 directly opposite to the opening 26 to block the opening 26, the slurry is prevented from splashing into the opening 26. Therefore, the partition 27, the shielding plate 23, and the connecting plate 22 form a plurality of barriers to prevent the slurry from splashing out of the vent 21, effectively solving the problem of slurry splashing. By setting the partition 27 tilted toward the center of the cup body 10 along the rotation direction of the crushing knife 11, the partition 27 can be used to block the opening 26 while also being used to drain the slurry toward the center of the cup body 10, which is conducive to achieving thorough crushing and improving the crushing effect.

[0049] As another more preferred embodiment, Figure 2 As shown, an extension plate 25 connected to the enclosure 24 is provided on the opposite side of the connecting plate 22 . The extension plate 25 extends downward from the top wall of the cup cover 20 . The end of the extension plate 25 , the end of the enclosure 24 and the end of the shielding plate 23 form an opening 26 .

[0050] By providing the extension plate 25, the end of the extension plate 25, the end of the enclosure 24 and the end of the shielding plate 23 form an opening 26, which is helpful to reduce the open area of ​​the opening 26, reduce the probability of slurry splashing, and effectively solve the problem of slurry splashing.

[0051] In the implementation example 1, the partition plate 27 is used to block the opening 26 , and the extension plate 25 is provided to reduce the area of ​​the opening 26 , thereby improving safety.

[0052] In fact, in other implementation examples, a partition 27 can be provided alone on the side opposite to the opening 26, without the need to provide an extension plate 25; or, an extension plate 25 can be provided alone to reduce the size of the opening 26, and the partition 27 can be omitted, both of which can achieve a good effect of preventing slurry from splashing, while also simplifying the structure of the cup cover 20.

[0053] In implementation example 1, the vent hole 21 is a waist-shaped hole, the connecting plate 22 is an arc-shaped plate that follows the length direction of the waist-shaped hole, and the surrounding plate 24 is an arc-shaped plate that follows the width direction of the waist-shaped hole.

[0054] In fact, the shape of the air holes 21 in the present invention is not limited to the above-mentioned one. For example, the air holes 21 can be square holes, circular holes, elliptical holes or other irregular shapes.

[0055] Of course, it should be noted that, in this embodiment, the enclosure 24 is provided at both side ends of the connecting plate 22 . In fact, the enclosure 24 may be provided only at the end of the connecting plate 22 facing the flow.

[0056] In addition to the form in the implementation example 1, the connecting plate 22 of the present invention can also be in other forms.

[0057] In the implementation example 2, the connecting plate 22 extends in a ring shape along the circumference of the air vent 21 , and a transverse opening 26 is provided on the connecting plate 22 .

[0058] Preferably, the shapes of the connecting plate 22 and the air hole 21 match; of course, the shapes of the connecting plate 22 and the air hole 21 may be different. For example, no matter what shape the air hole 21 is, the connecting plate 22 is annular to facilitate cleaning and avoid dead corners for dirt.

[0059] By extending the connecting plate 22 into a ring shape along the circumference of the air hole 21 and setting a transverse opening 26 on the connecting plate 22, an air passage is formed between the opening 26 and the air hole 21. The entrance of the air passage is the transverse opening 26. Compared with the traditional ventilation method that penetrates from top to bottom, it effectively reduces the splashing and spraying of slurry.

[0060] In implementation example 3, if Figure 6 As shown, the connecting plate 22 is a vertically extending flat plate, and the connecting plate 22 is located on one side of the vent hole 21 (as shown in FIG. Figure 6 The middle connecting plate 22 is located radially outside the air hole 21, and the shielding plate 23 is laterally bent from the bottom end of the connecting plate 22 to form an open air path.

[0061] Preferably, if Figure 6 As shown, a partition plate 27 is provided in the bending direction of the shielding plate 23 .

[0062] In a preferred embodiment, Figure 1 As shown, a handle 30 is protruded upward from the center of the top wall of the cup cover 20. More preferably, a groove 32 is formed downward on the top wall of the cup cover 20, and the handle 30 is protruded in the groove 32.

[0063] Specifically, the handle 30 and the cup cover 20 are separately provided and fixedly connected by fasteners, such as Figure 1 , Figure 5 As shown, the screw 31 locks the handle 30 in the groove of the cup cover from bottom to top.

[0064] Preferably, a rotation-stopping structure is provided between the handle 30 and the cup cover 20 , such as the rotation-stopping structure comprising a rotation-stopping groove provided on the handle 30 and a rotation-stopping rib provided on the cup cover 20 , and the rotation-stopping groove and the rotation-stopping rib are plug-fitted.

[0065] A handle 30 is protruded upward at the center of the top wall of the cup cover 20. Compared with the traditional method of protruding the handle 30 on the edge of the cup cover 20, the volume of the cup cover 20 can be reduced and the structure of the cup cover 20 can be simplified. At the same time, when the user grasps the handle 30, it is prevented from being interfered by the handle and other structures on the cup body 10, which facilitates the user's lid lifting operation and improves the user experience.

[0066] By providing a groove on the top wall of the cup cover 20, and the handle 30 protruding in the groove, the overall height of the cup cover 20 can be reduced while ensuring that the user has enough space to grasp the handle 30, and the height of the whole machine is reduced, which is convenient for the user to open the cover and store. By providing the handle 30 and the cup cover 20 separately, the shape of the handle 30 can be flexibly selected according to actual needs. The cup cover 20 is formed by a universal mold, which is convenient for mass production and reduces production costs. A rotation-stopping structure is provided between the handle 30 and the cup cover 20 to ensure the matching stability of the handle 30 and the cup cover 20, and reliable use.

[0067] Preferably, Figure 1-5 As shown, the cup cover 20 also has a side wall extending downward from the edge of the top wall, the side wall extends into the cup body 10 and is radially limited to cooperate with the side wall of the cup body 10, a magnet 40 is fixedly mounted on the side wall, and a detection element 42 cooperating with the magnet 40 is installed on the outer side of the cup body 10. In this embodiment, Figure 5 As shown, the cup cover, magnet, cover plate, handle and sealing ring constitute the cup cover assembly. Figure 4 As shown, preferably, the detection element 42 is installed in the handle on the side of the cup body.

[0068] By setting a magnet 40 on the side wall of the cup cover 20 and installing a detection element 42 on the outside of the cup body 10, the cup cover 20 is detected in place. When the detection element 42 fails to detect the magnet 40, the whole machine recognizes that the cup cover 20 is not installed in place and stops working, thereby effectively avoiding the danger of slurry splashing. The side wall of the cup cover 20 is used to achieve radial limitation of the cup cover 20 and the cup body 10, and at the same time provide a mounting position for the magnet 40. There is no need to extend the top wall of the cup cover 20 outward to install the magnet 40, which reduces the volume of the cup cover 20, simplifies the structure of the cup cover 20, and saves production costs.

[0069] More preferably, if Figure 4 As shown, a sealing ring 28 is provided on the side wall of the cup cover 20 , and the sealing ring 28 is interference fit with the side wall of the cup body 10 , and the magnet 40 is located above the sealing ring 28 .

[0070] More preferably, if Figure 5 As shown, the magnet 40 is fixed to the side wall of the cup cover 20 through the cover plate 41, and the cover plate 41 and the cup cover 20 are fixed by ultrasonic welding, clamping, etc.

[0071] By providing a sealing ring on the cup cover 20, the matching gap between the cup body 10 and the cup cover 20 is further sealed to prevent the slurry from splashing or overflowing the cup body 10, which is safe to use. The magnet 40 is arranged above the sealing ring to avoid the influence of steam on the magnet 40 during the processing, so that the magnet 40 and the detection element 42 can be matched reliably to achieve accurate lid closing detection.

[0072] Of course, the fixing of the handle and the cup cover of the present invention is not limited to the above-mentioned one. In fact, the handle can be integrally formed in the middle of the cup cover; or, the handle can be fixedly connected to the cup cover by means of a buckle or the like.

[0073] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0074] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0075] The above are only embodiments of the present invention and are not intended to limit the present invention.
