Description

Technical Field

[0001] The utility model belongs to the technical field of food processing accessories, and in particular relates to a cup body component of a food processing machine. Background Art

[0002] Existing food processing machines, such as soymilk machines, usually need to install an anti-overflow detection structure to prevent the slurry from overflowing after boiling. There are two main existing anti-overflow detection methods: one is contact anti-overflow electrode detection, in which the boiling slurry overflows and contacts the anti-overflow electrode, and the potential of the anti-overflow electrode is changed to achieve anti-overflow detection. When this detection method is used in a food processing machine, the anti-overflow electrode must be set in a place where the slurry can reach the glass cup body, which is easy to adhere to the slurry and bring inconvenience to cleaning; another anti-overflow detection method is remote detection, by setting a detection board on the outside of the insulating glass cup body, the detection board is attached to the capacitor electrode, the capacitance of the detection board changes with the volume of the liquid in the glass cup body, and the remote liquid level detection or anti-overflow detection is achieved without contact with the liquid, which is convenient for cleaning and has a high degree of intelligence.

[0003] For example, a patent application with application number 201720526032.4 discloses a food processor with good anti-overflow effect, including a base with a built-in motor and a mixing cup arranged above the base, the mixing cup includes a glass cup with a handle and a water level detection structure arranged on the outer side of the glass cup, the water level detection structure includes a detection component fitted on the outer wall of the glass cup and a capacitive sensing plate connected to the detection component, a handle shell is mounted on the handle, the handle shell includes an arc-shaped cavity matching the handle and a positioning groove for embedding the capacitive sensing plate, the capacitive sensing plate is positioned at a preset position adjacent to the outer wall of the glass cup through the handle shell, and then, a waterproof film is added between the handle shell and the glass cup to prevent the capacitive sensing plate from short-circuiting due to water entering.

[0004] In the above technology, since the outer wall of the glass cup is a cylindrical shape with an arc and the sensor plate is a strip-shaped flat plate, the sensor plate is directly positioned on the smooth glass cup through the handle shell, which will cause the sensor plate to be difficult to position and slide relative to the cup body, resulting in inaccurate assembly position of the sensor plate, affecting the detection accuracy; after the sensor plate is installed in place, the edge of the sensor plate cannot fit tightly with the glass cup, and it is easy to tilt up and cause the sensor plate to move, and the sensor plate positioning is still unreliable and the detection is inaccurate.

[0005] Moreover, the existing glass cups used for air detection are usually stretched tube glass cups. The wall thickness of the tube glass cup is small, which can reduce the air distance of the sensor plate. However, due to the small wall thickness of the glass cup, the sensor plate must be installed and positioned by other mounting structures such as the handle shell. On the one hand, the assembly process is complicated, the positioning of the sensor plate and the glass cup is difficult, and the fit cannot be guaranteed, which affects the detection accuracy. On the other hand, due to the installation error between the handle shell and the glass cup during the assembly process, when the detection plate is positioned by the handle shell, the relative position between the detection plate and the glass cup is not accurately assembled, the positioning of the detection plate is deviated, and the water level height actually detected by the detection plate is deviated from the preset water level height, resulting in inaccurate detection. At the same time, since the detection plate is sealed by a waterproof film that is separately clamped between the glass cup and the handle shell, the assembly process is further complicated and the assembly error is increased. Utility Model Content

[0006] The utility model provides a cup body assembly for a food processing machine. By optimizing the positioning and fixing method between a detection plate and a glass cup body, the utility model solves the problems in the prior art of difficult positioning between the detection plate and the glass cup body, resulting in detection plate offset and inaccurate detection, and at the same time solves the technical problems of complex assembly and sealing of the detection plate.

[0007] The technical solution adopted by the utility model is:

[0008] The utility model provides a cup body component of a food processing machine, comprising a glass cup body, a detection plate arranged on the outer side of the glass cup body for detecting the liquid level in the air, the outer wall of the glass cup body is provided with a vertically extending positioning groove, the detection plate is positioned in the positioning groove, and the outer side of the detection plate is encapsulated in the positioning groove by a glue filling layer to form a whole with the glass cup body.

[0009] The cup body assembly provided by the utility model is provided with a vertically extending positioning groove on the outer wall of the glass cup body. The detection plate is directly positioned in the positioning groove. The groove wall of the positioning groove limits the detection plate, and the detection plate is prevented from sliding and shifting during and after the installation of the detection plate. The detection plate is easy to position and the positioning is reliable, further ensuring the accurate installation position of the detection plate. At the same time, the side wall of the positioning groove protects the edge of the detection plate, reduces the probability of the edge of the detection plate warping and position shifting, and improves the fitting effect of the detection plate and the glass cup body, which is beneficial to shortening the spacing distance of the detection plate and improving the detection accuracy. On the basis of using the positioning groove to position and pre-install the detection board, the positioning groove is used to provide a glue injection space, so that the detection board can be directly fixed to the glass cup body by glue injection. After the detection board and the bottom wall of the positioning groove are tightly fitted, the flowing colloid is filled into the outer side of the detection board and the positioning groove to seal the detection board, so that the outer side of the detection board is encapsulated in the positioning groove through the glue injection layer to form a whole with the glass cup body. The detection board and the glass cup body are fixed in one step, eliminating the cumbersome assembly steps and assembly errors caused by indirect fixation through the handle, greatly simplifying the assembly method, and while the detection board is fixed by the glue injection layer, the detection board is effectively sealed, ensuring that the detection board and the glass cup body are tightly fitted, and the gap between the detection board and the positioning groove is effectively sealed to prevent water vapor from entering. The sealing is reliable, eliminating the need for separate setting of sealing film and other operations, while simplifying the assembly, the waterproofness of the detection board is ensured, and the failure of the detection board due to water ingress and inaccurate detection are avoided, thereby improving the detection accuracy and reliability, extending the service life, and simplifying the assembly and sealing methods.

[0010] In a preferred embodiment, the outer side wall of the glass body is provided with a plane, and the positioning groove is formed on the plane.

[0011] By providing a plane on the outer wall of the glass cup body, the positioning groove is formed on the plane. Compared with the method of directly die-casting the positioning groove on the circumferential outer wall of the glass cup body, the position of the positioning groove can be made more precise, thereby improving the positioning accuracy of the detection plate and facilitating the accurate molding of the glass cup body. At the same time, molding the positioning groove on the plane is conducive to leveling the bottom surface of the positioning groove, which can not only improve the positioning effect of the detection plate and pre-install the detection plate well to simplify the assembly of the detection plate, but also improve the fit between the planar detection plate and the positioning groove, so that the detection element on the detection plate can effectively detect the liquid level inside the glass cup body, and the distance between the detection element and the liquid level is more uniform, thereby improving the consistency between the capacitor electrode on the detection plate and the liquid signal sensing, making the detection more sensitive and accurate, and avoiding misjudgment and insensitive triggering.

[0012] In a preferred embodiment, the bottom wall of the positioning groove is a positioning plane, and the inner side wall of the glass body is provided with an inner plane corresponding to the position of the positioning plane.

[0013] By setting the bottom wall of the positioning groove as a positioning plane and setting an inner plane corresponding to the position of the positioning plane on the inner wall of the glass cup body, the vertical and horizontal distances between the detection plate in the positioning groove and the liquid in the glass cup body are made consistent, and the detection is more accurate and sensitive. The bottom wall of the positioning groove is the positioning plane, which can not only improve the positioning effect of the detection plate and pre-install the detection plate to simplify the assembly of the detection plate, but also improve the fit between the planar detection plate and the positioning groove, so that the detection element on the detection plate can effectively detect the liquid level inside the glass cup body, and the distance between the detection element and the liquid level is more uniform, ensuring the consistency between the capacitor electrode on the detection plate and the liquid signal induction, making the detection more accurate and avoiding false detection.

[0014] In a preferred embodiment, the thickness of the glass body gradually decreases from bottom to top, and the depth of the positioning groove gradually decreases from bottom to top.

[0015] Since the wall thickness of a die-cast glass cup generally becomes thinner from bottom to top, gradually reducing the depth of the positioning groove from bottom to top is beneficial to making the distance from bottom to top between the bottom wall of the positioning groove and the inner wall of the glass cup body more uniform, thereby avoiding the risk of local insensitivity of the detection board or misjudgment, and improving the detection accuracy of the detection board.

[0016] In a preferred embodiment, the positioning groove is formed by a depression in the outer wall of the glass body; or, a rib is convexly provided on the outer wall of the glass body, and the rib and the outer wall of the glass body are combined to form the positioning groove.

[0017] Whether the positioning groove is formed by the depression of the outer wall of the glass cup body or by adding ribs, the detection plate can be accurately positioned and can be flexibly selected according to actual needs during the die-casting process of the glass cup body, thereby facilitating the subsequent assembly and fixation of the detection plate.

[0018] In a preferred embodiment, a laterally extending positioning portion is provided in the positioning groove, and the upper end or the lower end of the detection plate abuts against the positioning portion for limiting position.

[0019] By providing a laterally extending positioning portion in the positioning groove, the positioning portion is used to position the upper or lower end of the detection plate, so that the upper and lower ends of the detection plate are accurately positioned along the height direction (vertical direction) of the glass cup body, the installation height of the detection plate is accurate, and the detection range of the detection plate and the liquid level range in the glass cup body accurately correspond. Compared with the traditional technology of using handle positioning, the assembly error of the detection plate and the glass cup body is reduced, the detection range of the detection plate is accurate, and the detection accuracy is improved; along the circumferential direction of the glass cup body, the side wall of the positioning groove limits the circumferential position of the detection plate, during the installation process of the detection plate and after the installation, the detection plate is prevented from sliding and offsetting, the positioning is reliable, and the installation position of the detection plate is further accurate. Therefore, the positioning groove makes it easy to locate and pre-install the detection plate. At the same time, the positioning groove accurately limits the detection plate from multiple directions, which improves the detection accuracy of the detection plate, the detection sensitivity, and reduces the risk of misjudgment.

[0020] In a preferred embodiment, the upper end of the detection plate abuts against the positioning portion, and the lower end of the positioning groove is provided with a notch for wiring;

[0021] Since a general detection board generally includes a detection section and a signal processing section, in order to expand the detection range of the detection board, the detection section is generally close to the upper end to cover a larger cup body area, and the signal processing section is located at the lower end and connected to the lead. Therefore, the positioning portion is arranged at the top to enable the upper end of the detection board to be accurately positioned, and a notch is provided at the lower end of the positioning groove to enable the lead to pass through, which is conducive to the arrangement of the leads, while taking into account the expansion of the detection area of ​​the detection board, and the structural reliability is stronger.

[0022] In a preferred embodiment, the positioning portion is a positioning rib located at the end of the positioning groove; or, the positioning portion is an end wall of the positioning groove.

[0023] The positioning portion can be formed by setting a positioning rib at the end of the positioning groove, that is, the upper end or the lower end, or it can be directly formed using the upper end wall or the lower end wall of the positioning groove, so as to facilitate the precise determination of the upper end position of the detection plate, ensure the vertical detection range of the detection plate is accurate, and improve the detection accuracy.

[0024] In a preferred embodiment, the cup body assembly further comprises an annular member clamped around the glass cup body and the outer periphery of the detection plate, so that the detection plate is pressed against the positioning groove;

[0025] By setting a ring member that is clamped around the glass cup body and the outer periphery of the detection plate, it can be used to limit the detection plate before the detection plate is glued, ensuring accurate pre-positioning of the detection, facilitating glue pouring, and simplifying the operation. At the same time, the ring member can also be used to further strengthen the connection between the detection plate and the glass cup body after the detection plate is glued and fixed, thereby improving the fixing reliability of the detection plate and preventing the detection plate from shifting.

[0026] In a preferred embodiment, the distance W2 between the bottom wall of the positioning groove and the inner wall of the glass body satisfies 1mm≤W2≤4mm.

[0027] Generally, the wall thickness of the glass cup body is set at 5mm-10mm, and the distance between the bottom wall of the positioning groove and the inner wall of the glass cup body is 1-4mm, ensuring that the spacing distance of the detection plate is reasonable, so as to ensure that the liquid in the glass cup body can enter the effective detection range of the detection plate, and ensure the effectiveness and sensitivity of the detection. At the same time, the wall thickness can be prevented from being too thin with the help of the die-casting process. For example, a high-boron glass cup body made of liquid die-casting can be used to make the structural strength of the glass cup body meet the requirements.

[0028] In a preferred embodiment, the cup body assembly also includes a mounting base fixed to the bottom of the glass cup body, the mounting base is provided with a second positioning groove aligned with the positioning groove, the lower end of the detection plate extends into the second positioning groove, and the detection plate is integrated with the glass cup body and the mounting base through a glue filling layer.

[0029] By setting a second positioning groove and extending the lower part of the detection plate into the second positioning groove, the upper part of the detection plate can correspond to the outer side of the glass cup body more fully and comprehensively, and the lower detection limit of the detection plate is closer to the bottom of the glass cup body, so that the detection range of the detection plate can be reasonably and fully matched according to the height of the glass cup body, thereby reducing the occurrence of detection blind spots, realizing low water level detection and even dry burning detection, as well as high water level detection and overflow prevention detection, expanding the vertical detection range of the detection plate, and expanding the scope of application.

[0030] In a preferred embodiment, a mounting gap is formed between the second positioning groove and the positioning groove, the cup body assembly further comprises a shielding member having a sealing sleeve arranged outside the mounting gap, and the detection plate is arranged outside the shielding member;

[0031] Generally, the mounting seat has the function of supporting the glass cup body or using the mounting seat to install the heating plate so that the heating plate is fixed to the bottom end of the glass cup body. Therefore, an annular mounting gap is inevitably formed between the mounting seat and the glass cup body to achieve the above-mentioned function of the mounting seat. By setting a shielding member to seal the mounting gap, the detection plate is set on the outside of the shielding member, and the shielding member can be used to seal the mounting gap between the first positioning groove and the second positioning groove. On the one hand, it can prevent the water vapor passing through the mounting gap from damaging the detection plate or affecting the detection of the detection plate, and avoid water in the mounting gap. On the other hand, during the glue filling process, it can prevent the flowing colloid from flowing into the gap, and use the shielding member to support and limit the inner side of the detection plate to achieve reliable positioning of the detection plate.

[0032] In a preferred embodiment, the detection plate includes a detection section for detecting the liquid level and a signal processing section located below the detection section, and the detection section and the signal processing section are respectively positioned in the positioning groove and the second positioning groove.

[0033] By positioning the detection section and the signal processing section in the positioning groove and the second positioning groove respectively, the detection section is used to fully match the height of the glass cup body, thereby expanding the detection range, and the signal processing section is used to set the chip and the terminal, and the chip and the terminal are helped to play a certain heat insulation role through the mounting seat, thereby reducing the heat transfer from the glass cup body to the chip, avoiding overheating of the chip and the terminal and causing detection failure, so that the detection is accurate and lasting.

DETAILED DESCRIPTION

[0048] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0049] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below. It should be noted that the embodiments of the present invention and the features in each embodiment may be combined with each other without conflict.

[0050] In addition, in the description of the present invention, it should be understood that the terms "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0051] like Figure 1-9 As shown, the utility model provides a cup body assembly of a food processing machine in one embodiment, including a cup body assembly, the cup body assembly including a glass cup body 20, such as a die-cast high-boron glass cup, and also including a detection plate 40 arranged on the outside of the glass cup body 20 for detecting the liquid level in the air, the outer wall of the glass cup body 20 is provided with a vertically extending positioning groove, namely a first positioning groove 201, the detection plate 40 is positioned in the positioning groove, and the outer side of the detection plate 40 is encapsulated in the positioning groove by a glue potting layer to form a whole with the glass cup body 20.

[0052] In a preferred embodiment, the cup body assembly further includes a protective member 50 , and the detection plate 40 is hidden by the protective member 50 after being packaged.

[0053] In this embodiment, if Figure 1 As shown, the food processor is a food processor that does not need to be washed by hands. The food processor also includes a main unit 10. The main unit 10 is provided with a control device connected to a detection board 40. The glass cup body 20 is detachably mounted on the main unit 10. A heating plate and a crushing knife are also provided at the bottom of the glass cup body 20 to prepare soy milk.

[0054] Preferably, if Figure 2 As shown, the detection board 40 includes a detection section 401, and a plurality of capacitor electrodes 41 are arranged vertically at intervals on the inner side of the detection section 401 to detect liquid level signals of different heights, thereby realizing low liquid level detection, dry burning detection, and high liquid level overflow signal detection, etc. The detection board 40 also includes a signal processing section 402. Figure 6 As shown, a chip 42 and a connection terminal 43 are provided on the outer side of the signal processing section 402 , and the connection terminal 43 is connected with a lead wire for connecting with a control device.

[0055] It should be noted that, in the utility model, at least part of the detection board is encapsulated in the positioning groove by the glue potting layer. For example, in the present embodiment, only the detection section of the detection board 40 at the upper part is positioned in the positioning groove by the glue potting layer to form an integral body with the glass cup body, and the signal processing section of the detection board extends out of the positioning groove. Optionally, the signal processing section of the detection board is suspended or extends to be positioned in the second positioning groove of the mounting seat.

[0056] The cup body assembly provided by the utility model is provided with a vertically extending positioning groove on the outer wall of the glass cup body 20, and the detection plate 40 is directly positioned in the positioning groove. The groove wall of the positioning groove limits the detection plate 40, and during the installation process of the detection plate 40 and after the installation, the detection plate 40 is prevented from sliding and shifting. The detection plate 40 is easy to position and the positioning is reliable, further ensuring the accurate installation position of the detection plate 40; at the same time, the side wall of the positioning groove protects the edge of the detection plate 40, reduces the probability of the edge of the detection plate 40 warping and position shifting, and improves the fitting effect of the detection plate 40 and the glass cup body 20, which is beneficial to reduce the spacing distance of the detection plate 40 and improve the detection accuracy. On the basis of using the positioning groove to position and pre-install the detection board 40, the positioning groove is used to provide a glue injection space, so that the detection board 40 is directly fixed to the glass cup body 20 by means of glue injection. After the detection board 40 and the bottom wall of the positioning groove are tightly fitted, the flowing colloid is filled into the outer side of the detection board 40 and the positioning groove to seal the detection board 40, so that the outer side of the detection board 40 is encapsulated in the positioning groove through the glue injection layer to form a whole with the glass cup body 20. The fixation between the detection board 40 and the glass cup body 20 is completed in one step, eliminating the assembly caused by indirect fixation through the handle The steps are complicated and the assembly errors are reduced, which greatly simplifies the assembly method. The test board 40 is fixed by the glue layer, and the test board 40 is effectively sealed, ensuring the close contact between the test board 40 and the glass cup body 20, effectively sealing the gap between the test board 40 and the glass cup body 20, preventing water vapor from entering, and reliably sealing. It eliminates the need to set up a separate sealing film and other operations. While simplifying the assembly, it also ensures the waterproofness of the test board 40, avoids the failure of the test board 40 due to water ingress and inaccurate detection, improves the accuracy and reliability of detection, extends the service life, and simplifies the assembly and sealing method. After the test board 40 is packaged, it is hidden by the protective member 50 to avoid the test board 40 from being exposed, and a protective barrier is added to the test board 40 to prevent the test board 40 from being disturbed by the outside world, ensuring the accuracy of the detection, extending the service life of the test board 40, and improving the waterproof and dustproof effect of the test board 40. At the same time, it will not affect the accurate positioning of the test board 40, and the overall structure is reliable. In addition, the glass cup body 20 in the utility model adopts a die-cast glass cup body 20, which is easier to form a thick cup wall and a positioning groove than a stretched glass cup body 20. While realizing the positioning groove for positioning the detection plate 40, it can also ensure the overall structural strength of the glass cup body 20 and the structure is reliable.

[0057] The present invention does not limit the structure of the positioning groove. For example, it can adopt any of the following implementation examples:

[0058] Implementation example 1, such as Figure 5 , Figure 6 , Figure 7 As shown, the outer wall of the glass body 20 is provided with a plane 23, and the positioning groove is formed on the plane 23. Specifically, as shown in FIG. Figure 6As shown, two vertical ribs 24 are protruded on the plane 23, and the two vertical ribs 24 and the plane 23 form positioning grooves.

[0059] It should be noted that the plane can be formed by die-casting together with the glass cup body during the die-casting process of the glass cup body; or, the plane is formed by cutting the outer wall of the glass cup body flat; or, the plane is formed by providing an outwardly protruding boss on the outer wall of the glass cup body.

[0060] By providing a plane 23 on the outer wall of the glass cup body 20, a positioning groove is formed on the plane 23. Compared with the method of directly casting a recessed positioning groove on the circumferential outer wall of the glass cup body 20, the position of the positioning groove can be made more precise, thereby improving the positioning accuracy of the detection plate 40 and facilitating the accurate molding of the glass cup body 20. At the same time, molding the positioning groove on the plane 23 is conducive to leveling the bottom surface of the positioning groove, which can not only improve the positioning effect of the detection plate 40, but also pre-install the detection plate 40 to simplify the assembly of the detection plate 40, and at the same time improve the fit between the planar detection plate 40 and the positioning groove, so that the detection element on the detection plate 40 can effectively detect the liquid level inside the glass cup body 20, and the distance between the detection element and the liquid level is more uniform, thereby improving the consistency between the capacitor electrode 41 on the detection plate 40 and the liquid signal sensing, and the detection is more sensitive and accurate, avoiding misjudgment and insensitive triggering.

[0061] As a more preferred implementation of this example, Figure 6 As shown, the bottom wall of the positioning groove is a positioning plane, combined with Figure 3 As shown, the inner wall of the glass body 20 is provided with an inner plane 25 corresponding to the position of the positioning plane.

[0062] By setting the bottom wall of the positioning groove as a plane and setting an inner plane 25 corresponding to the position of the positioning plane on the inner wall of the glass cup body 20, the vertical and horizontal distances between the detection plate 40 located in the positioning groove and the liquid in the glass cup body 20 are made consistent, and the detection is more accurate and sensitive. The bottom wall of the positioning groove is a positioning plane, which can not only improve the positioning effect of the detection plate 40 and pre-install the detection plate 40 to simplify the assembly of the detection plate 40, but also improve the fit between the planar detection plate 40 and the positioning groove, so that the detection element on the detection plate 40 can effectively detect the liquid level inside the glass cup body 20, and the distance between the detection element and the liquid level is more uniform, ensuring the consistency between the capacitor electrode 41 on the detection plate 40 and the liquid signal sensing, so that the detection is more accurate and avoids false detection.

[0063] As a preferred embodiment, Figure 4 , Figure 5As shown, the thickness of the glass body 20 gradually decreases from bottom to top, and the depth of the positioning groove gradually decreases from bottom to top. Figure 4 As shown, according to the change in thickness of the glass cup body 20, the inner diameter of the glass cup body 20 increases from bottom to top, so that the bottom wall of the first positioning groove 201 tilts outward from bottom to top, thereby achieving a change in the groove depth of the positioning groove.

[0064] Since the wall thickness of a die-cast glass cup generally becomes thinner from bottom to top, gradually reducing the depth of the positioning groove from bottom to top is beneficial to making the distance from bottom to top between the bottom wall of the positioning groove and the inner wall of the glass cup body 20 more uniform, thereby avoiding the risk of local insensitivity of detection of the detection plate 40 or misjudgment, and improving the detection accuracy of the detection plate 40.

[0065] As a preferred embodiment, the wall thickness W1 of the glass cup body 20 satisfies: 5mm≤W1≤10mm; and the distance W2 between the bottom wall of the positioning groove and the inner wall of the glass cup body 20 satisfies: 1mm≤W2≤4mm.

[0066] It should be noted that, when the wall thickness of the glass body 20 is uneven, the above W1 is the minimum wall thickness of the glass body 20 outside the positioning groove; when the wall thickness of the glass body 20 is uniform, W1 is the average wall thickness of the glass body 20. When the depth of the positioning groove is uneven, W2 refers to the minimum distance between the bottom wall of the positioning groove and the inner wall of the glass body 20.

[0067] By setting the wall thickness of the glass cup body 20 to 5mm-10mm and satisfying the distance between the bottom wall of the positioning groove and the inner wall of the glass cup body 20 of 1-4mm, the air distance of the detection plate 40 is ensured to be reasonable, so as to ensure that the liquid in the glass cup body 20 can enter the effective detection range of the detection plate 40, thereby ensuring the effectiveness and sensitivity of the detection. At the same time, the wall thickness can be prevented from being too thin with the aid of the die-casting process. For example, a high-boron glass cup body 20 is used by liquid die-casting, so that the structural strength of the glass cup body 20 meets the requirements.

[0068] In implementation example 2, the positioning groove is formed by being recessed directly relative to the circumferential outer wall of the glass cup body 20 .

[0069] In this embodiment, preferably, the bottom wall of the positioning groove is a positioning plane.

[0070] More preferably, the inner side wall of the glass body is provided with an inner plane corresponding to the position of the positioning plane.

[0071] It can be understood that, in this embodiment, optionally, the thickness of the glass cup body 20 gradually becomes thinner from bottom to top, and the depth of the positioning groove gradually decreases from bottom to top.

[0072] In implementation example 3, a rib is directly protruded from the circumferential outer wall of the glass cup body 20 , and the rib and the outer wall of the glass cup body 20 are combined to form a positioning groove.

[0073] It can be understood that no matter the positioning groove is formed by the depression of the outer wall of the glass cup body 20 or by adding ribs, the detection plate 40 can be accurately positioned, and can be flexibly selected according to actual needs during the die-casting process of the glass cup body 20, thereby facilitating the subsequent assembly and fixation of the detection plate 40.

[0074] In a preferred embodiment, Figure 6 As shown, a laterally extending positioning portion is provided in the positioning groove, and the upper end or the lower end of the detection plate 40 abuts against the positioning portion for limiting position. Preferably, the groove depth of the positioning groove is W and W≥1mm.

[0075] As a more preferred embodiment, Figure 6 As shown, the upper end of the detection plate 40 is in contact with the positioning portion, and the lower end of the positioning groove is provided with a notch 26 for wiring.

[0076] By providing a laterally extending positioning portion in the positioning groove, the upper end or the lower end of the detection plate 40 is positioned by using the positioning portion, so that the upper end and the lower end of the detection plate 40 are accurately positioned along the height direction (vertical direction) of the glass cup body 20, the installation height of the detection plate 40 is accurate, and the detection range of the detection plate 40 and the liquid level range in the glass cup body 20 accurately correspond. Compared with the conventional technology of using a handle for positioning, the assembly error of the detection plate 40 and the glass cup body 20 is reduced, the detection range of the detection plate 40 is accurate, and the detection accuracy is improved; along the circumferential direction of the glass cup body 20, the side wall of the positioning groove limits the circumferential position of the detection plate 40, during the installation process of the detection plate 40 and after the installation, the detection plate 40 is prevented from sliding and deflecting, the positioning is reliable, and the installation position of the detection plate 40 is further accurate. Therefore, the positioning groove makes it easy to locate and pre-install the detection plate 40, and at the same time, the positioning groove accurately limits the detection plate 40 from multiple directions, thereby improving the detection accuracy of the detection plate 40, detecting sensitivity, and reducing the risk of misjudgment.

[0077] The positioning portion is arranged at the top so that the upper end of the detection board 40 can be accurately positioned, and a notch is arranged at the lower end of the positioning groove to realize the passage of the lead wire, which is beneficial to the arrangement of the lead wire and at the same time takes into account the expansion of the detection area of ​​the detection board 40, and the structural reliability is stronger.

[0078] Of course, the structure of the positioning portion may be selected as the following implementation examples:

[0079] In implementation example 4, the positioning portion is a positioning convex rib arranged at the upper end of the positioning groove;

[0080] Implementation Example 5, such as Figure 6 As shown, the positioning portion is the upper end wall of the positioning groove.

[0081] The positioning portion can be formed by setting a positioning rib at the end of the positioning groove alone, or it can be directly formed by using the end wall of the positioning groove, so as to facilitate the accurate determination of the upper end position of the detection plate 40, ensure the vertical detection range of the detection plate 40 is accurate, and improve the detection accuracy.

[0082] In another preferred embodiment, Figure 6 As shown, the cup mouth of the glass cup body 20 is provided with an annular rib 27 protruding outward and a fixing seat 28 fixedly mounted on the annular rib, and handles 29 are provided on both sides of the fixing seat, so that the glass cup body 20 can be detachably mounted on the host 10.

[0083] More preferably, the annular rib forms the upper end wall of the positioning groove, and the upper end of the detection section 401 abuts against the annular rib to be positioned in the positioning groove. Alternatively, the annular rib forms the above-mentioned positioning convex rib, and the upper end of the detection section 401 abuts against the annular rib to be positioned in the positioning groove.

[0084] By setting an annular rib at the mouth of the glass cup body 20, the annular rib is used to fix the fixing seat and handles are formed on both sides of the fixing seat, so that the user can take and place the glass cup body 20 from bottom to top, which is labor-saving and convenient. The upper end wall of the positioning groove is formed by the annular rib, and the upper end of the detection section 401 abuts against the annular rib to be positioned in the positioning groove. Therefore, the annular rib provides installation space for the fixing seat and the handle, making the structure reliable and stable. At the same time, the annular rib is also used to position the upper end of the detection section 401, improve the position of the detection plate 40 accurately, reduce installation errors and measurement errors, and achieve a compact structure.

[0085] In a preferred embodiment, the cup body assembly further includes an annular member (not shown) clamped around the outer circumference of the glass cup body 20 and the detection plate 40 so that the detection plate 40 is pressed against the positioning groove.

[0086] It should be noted that the annular member can be used to pre-position the detection plate 40 before the glue pouring operation, or the annular member can be used to strengthen the positioning of the detection plate 40 after the glue pouring operation, thereby improving the fixing reliability of the detection plate 40 and preventing the detection plate 40 from being offset.

[0087] The utility model provides a cup body assembly in a more preferred embodiment, such as Figure 5-9 As shown, the cup body assembly not only includes a positioning groove set on the glass cup body 20, namely, a first positioning groove 201, but also includes a mounting base 30 fixed at the bottom of the glass cup body 20, and the outer wall of the mounting base 30 is provided with a second positioning groove 301 aligned with the first positioning groove 201, and the lower end of the detection plate 40 extends into the second positioning groove 301 and is positioned by the second positioning groove 301.

[0088] like Figure 6 ,7 As shown, the detection plate 40 includes a detection section 401 for detecting the liquid level and a signal processing section 402 located below the detection section 401. Figure 8 , 9 As shown, the detection section 401 and the signal processing section 402 are positioned in the first positioning groove 201 and the second positioning groove 301 respectively.

[0089] Specifically, combined Figure 1 As shown, the food processor still adopts a food processor that does not need to be washed by hands. The food processor also includes a main unit 10. The main unit 10 is provided with a control device connected to a detection board 40. The glass cup body 20 is detachably mounted on the main unit 10. A heating plate and a crushing knife are also provided at the bottom of the glass cup body 20 to prepare soy milk.

[0090] Preferably, a plurality of capacitor electrodes 41 are arranged at vertical intervals on the inner side surface of the detection section 401 to detect liquid level signals at different heights, thereby realizing low liquid level detection, dry burning detection, and high liquid level overflow signal detection, etc. A chip 42 and a wiring terminal 43 are provided on the outer side surface of the signal processing section 402, and the wiring terminal 43 is connected with a lead for connecting to a control device.

[0091] The cup body assembly provided in the present embodiment is provided with a positioning groove for positioning the detection plate 40. The groove wall of the positioning groove limits the detection plate 40. During the installation process of the detection plate 40 and after the installation, the detection plate 40 is prevented from sliding and shifting. The detection plate 40 is easy and reliably positioned, which reduces the difficulty of assembly and further ensures that the installation position of the detection plate 40 is accurate. At the same time, the side wall of the positioning groove protects the edge of the detection plate 40, reduces the probability of the edge of the detection plate 40 warping and position shifting, and improves the fitting effect of the detection plate 40 and the glass cup body 20, which is beneficial to reduce the spacing distance of the detection plate 40 and improve the detection accuracy. The positioning groove includes a first positioning groove 201 vertically arranged on the outer wall of the glass cup body 20 and a second positioning groove 301 extending from the first positioning groove 201 to the outer wall of the mounting seat 30. The detection section 401 and the signal processing section 402 of the detection board 40 are respectively located in the first positioning groove 201 and the second positioning groove 301, so that the detection section 401 of the detection board 40 can correspond to the outer side of the glass cup body 20 more fully and comprehensively, and the detection lower limit of the detection board 40 is closer to the bottom of the glass cup body 20, so that the detection range of the detection board 40 can be reasonably and fully matched according to the height of the glass cup body 20, reducing the occurrence of detection blind spots, realizing low water level detection and even dry burning detection, as well as realizing high water level detection and overflow prevention detection, expanding the vertical detection range of the detection board 40, and expanding the scope of application. By setting the mounting seat 30, the second positioning groove 301 is located on the outer wall of the mounting seat 30, and the signal processing section 402 is located in the second positioning groove 301. Therefore, the chip 42 and the terminal 43 set in the signal processing section 402 can play a certain heat insulation role through the mounting seat 30, reducing the heat transfer from the glass cup body 20 to the chip 42, avoiding overheating of the chip 42 and the terminal 43 and causing detection failure, so that the detection is accurate and durable.

[0092] In a preferred embodiment, Figure 7 , Figure 8 As shown, there is an annular installation gap between the glass cup body 20 and the mounting seat 30, and the installation gap separates the first positioning groove 201 and the second positioning groove 301. A shielding member 60 for shielding the installation gap is provided in the positioning groove formed by the first positioning groove 201 and the second positioning groove 301, and the detection plate 40 is arranged on the outside of the shielding member 60.

[0093] In this embodiment, if Fig. 9As shown, the glass cup body 20 includes a main section 21 and a contraction section 22 that is indented inward relative to the main section 21, and the mounting seat 30 is annular. A heating plate is mounted in the mounting seat 30 and is sleeved and fixed on the outer periphery of the contraction section 22 to fix the heating plate at the bottom end of the glass cup body 20. More preferably, the bottom wall of the first positioning groove 201 and the bottom wall of the second positioning groove 301 are arranged flush, and preferably, the first positioning groove 201 and the second positioning groove 301 are aligned up and down and the bottom wall of the first positioning groove 201 and the bottom wall of the second positioning groove 301 are located on the same plane, so as to save the need to set a step on the detection plate 40, so that the detection plate 40 as a whole fits with the bottom wall of the positioning groove.

[0094] By providing the main section 21 and the contraction section 22 that is indented inward relative to the main section 21, the mounting seat 30 is sleeved and fixed on the outer periphery of the contraction section 22, so that the mounting seat 30 of the glass cup body 20 can be reliably fixed, and the installation of the mounting seat 30 is simplified; because the contraction section 22 is indented inward, the outer wall of the mounting seat 30 and the outer wall of the glass cup body 20 can be nearly aligned after the mounting seat 30 is fixed, so as to facilitate the alignment of the bottom wall of the first positioning groove 201 and the second positioning groove 301, so as to facilitate the detection plate 40 to fit with the bottom wall of the positioning groove as a whole, improve the reliability of positioning and improve the sensitivity and accuracy of detection. Because in general, the detection plate 40 is planar on the side facing the glass cup body 20, the bottom wall of the first positioning groove 201 and the bottom wall of the second positioning groove 301 are set flush, which makes it easier to fit the detection plate 40 and the positioning groove well, so as to improve the accuracy of detection and the reliability of positioning.

[0095] It should be noted that, in other embodiments, the glass cup body 20 can be optionally selected as a straight cylinder with equal diameter, and the mounting seat 30 is sleeved on the bottom of the glass cup body 20. By setting a protrusion on one side of the glass cup body 20, the first positioning groove 201 is set on the protrusion, and the second positioning groove 301 is set on the mounting seat 30 to keep the first positioning groove 201 and the second positioning groove 301 flush.

[0096] Of course, the first positioning groove 201 and the second positioning groove 301 can be misaligned to a certain extent, and the detection plate 40 as a whole can be made to fit with the bottom walls of the first positioning groove 201 and the second positioning groove 301 by bending the connecting position between the detection section 401 and the signal processing section 402, or setting steps.

[0097] In this embodiment, a shielding member 60 for covering the installation gap is provided in the positioning groove formed by the first positioning groove 201 and the second positioning groove 301, and the detection board 40 is arranged on the outside of the shielding member 60. The shielding member 60 can be used to shield or seal the installation gap between the first positioning groove 201 and the second positioning groove 301 to prevent water vapor and dust passing through the installation gap from damaging the detection board 40 or affecting the detection of the detection board 40, and to prevent water from accumulating in the installation gap. The shielding member 60 is used to support and limit the inner side of the detection board 40, thereby realizing reliable positioning of the detection board 40.

[0098] Preferably, the shielding member 60 may adopt any of the following implementation examples:

[0099] Implementation Example 6, such as Fig.10 As shown, a sealing ring 70 is sleeved on the outer side of the installation gap, and the shielding member 60 is arranged on the sealing ring 70. More preferably, the sealing ring 70 is provided with an opening, and the shielding member 60 is connected to the opening and is recessed inwardly relative to the sealing ring 70.

[0100] As a preferred embodiment of the present embodiment, the outer side of the detection board 40 is encapsulated in the positioning groove by a glue potting layer.

[0101] A sealing ring 70 is sleeved on the outside of the installation gap to effectively seal the installation gap, thereby preventing water from leaking out of the glass cup body 20 and dust from entering and affecting the detection of the detection board 40, so that the detection board 40 can be effectively detected, and the shielding member 60 is set on the sealing ring 70. The two are combined into one with a compact structure, forming a comprehensive seal on the annular installation gap, so that the seal between the first positioning groove 201 and the second positioning groove 301 is connected, thereby improving the positioning and supporting effect of the detection board 40.

[0102] Since the annular installation gap separates the first positioning groove 201 and the second positioning groove 301, and the first positioning groove 201 and the second positioning groove 301 are recessed inward relative to the outer wall of the glass cup body 20, the shielding member 60 is connected to the opening and recessed inward relative to the sealing ring 70 by setting an opening in the sealing ring 70, so that the connection position of the shielding member 60 and the sealing ring 70 can match the recessed shape of the positioning groove, so that the shielding member 60 and the sealing ring 70 can fully seal the entire circle of the installation gap together, thereby improving the sealing effect. This is conducive to directly encapsulating the detection board 40 in the positioning groove with glue, and preventing the flowing colloid from flowing into the installation gap.

[0103] On the basis of using the positioning groove to position and pre-install the detection board 40, the positioning groove is used to provide a glue injection space, so that the detection board 40 is directly fixed to the glass cup body 20 by means of glue injection. After the detection board 40 and the bottom wall of the positioning groove are tightly fitted, the flowing colloid is filled into the outer side of the detection board 40 and the positioning groove to seal the detection board 40, so that the outer side of the detection board 40 is encapsulated in the positioning groove through the glue injection layer to form a whole with the glass cup body 20. The fixation between the detection board 40 and the glass cup body 20 is completed in one step, eliminating the assembly caused by indirect fixation through the handle The cumbersome steps and assembly errors are greatly simplified, and the test board 40 is fixed by the glue layer while being effectively sealed to ensure that the test board 40 and the glass cup body 20 are in close contact, and the gap between the test board 40 and the glass cup body 20 is effectively sealed to prevent water vapor from entering. The seal is reliable, and the operation of separately setting up a sealing film is omitted. While simplifying the assembly, the waterproofness of the test board 40 is ensured, and the test board 40 is prevented from failing due to water ingress and inaccurate detection, thereby improving detection accuracy and reliability, extending service life, and simplifying assembly and sealing methods.

[0104] like Fig. 9 As shown, the sealing ring 70 is provided with a connecting portion 72 located outside the shielding member 60 , and the connecting portion 72 and the shielding member 60 are enclosed to form an installation opening for the signal processing section 402 to pass through.

[0105] By setting the connecting portion 72, the connecting portion 72 and the shielding member 60 are enclosed to form an installation opening for the signal processing section 402 to pass through. Therefore, the installation opening is utilized to strengthen the limiting effect of the positioning groove on the detection plate 40, so that the detection plate 40 can be positioned both circumferentially and radially along the glass cup body 20, and the positioning is more comprehensive, which is convenient for subsequent fixing operations such as gluing or pressing the detection plate 40, greatly simplifying the difficulty of assembly, while ensuring the installation accuracy and detection accuracy of the detection plate 40.

[0106] In other embodiments, Fig.10 As shown, a block 71 for holding the detection plate is provided on the sealing ring 70;

[0107] By providing a clamping block 71 on the sealing ring 70, the detection board 40 is pressed and held on the outside of the shielding member 60 by the clamping block 71, so that while the shielding member 60 is used to seal the installation gap between the first positioning groove 201 and the second positioning groove 301, the clamping block 71 positions the outside of the detection board 40, so that the detection board 40 is pre-positioned in the positioning groove, further improving the positioning reliability of the detection board 40, and facilitating subsequent fixing operations such as gluing or pressing the detection board 40, greatly simplifying the assembly difficulty, and at the same time ensuring the installation accuracy and detection accuracy of the detection board 40.

[0108] Implementation Example 7, combined with Fig.10As shown, the shielding member 60 is connected to the sealing ring 70 as a whole, and the shielding member 60 includes a main body 61 and an extension portion 62 extending downward from the main body 61 to the second positioning groove 301, and the extension portion 62 isolates the second positioning groove 301 and the signal processing section 402;

[0109] In this embodiment, more preferably, the shielding member 60 defines a transition groove connecting the first positioning groove 201 and the second positioning groove 301, the detection plate 40 is pressed against the bottom wall of the transition groove, a retaining rib is provided at the edge of the transition groove, and the detection plate 40 is limited between the retaining rib and the bottom wall of the transition groove. The retaining rib can be selected as the above-mentioned block 71 or the connecting portion 72.

[0110] By setting the shielding member 60 as a main body 61 and an extension portion 62, the extension portion 62 is used to isolate the second positioning groove 301 and the signal processing section 402. Therefore, on the basis of using the mounting base 30 to insulate the signal processing section 402, the extension portion 62 is used to further enhance the insulation effect, thereby forming good insulation protection for the chip 42, the terminal block 43 and other structures of the signal processing section 402, thereby extending the service life and reducing the impact on the detection board 40.

[0111] Of course, it should be noted that in addition to the above-mentioned one-piece molding method, the main body 61 and the extension part 62 can also be separately molded. For example, the colloid is formed by pouring glue to form a shielding member 60 together with the main body 61, and the colloid simultaneously encapsulates the detection board 40 in the positioning groove.

[0112] Implementation Example 8. In this implementation example, the mounting seat 30 is non-annular. The mounting seat 30 is a mounting protrusion fixed to one side of the bottom of the glass cup body 20. The shielding member 60 includes a main body 61 and an extension portion 62 extending downward from the main body 61 to the second positioning groove 301. The extension portion 62 isolates the second positioning groove 301 and the signal processing section 402.

[0113] It should be noted that the fixing method of the mounting seat 30 of the utility model is not limited to the above-mentioned embodiment. In another preferred embodiment, the lower end of the glass cup body 20 is open and has an inner flange extending radially inward, a heating plate is provided above the inner flange, and the mounting seat 30 is located below the glass cup body 20, and the heating plate and the mounting seat 30 are fixedly connected to clamp the inner flange.

[0114] By setting an inner flange at the lower end of the glass cup body 20 and using a heating plate and a mounting seat 30 to fix and clamp the inner flange, the mounting seat 30 is fixed to the lower end of the glass cup body 20, the fixation is reliable and the installation of the mounting seat 30 is convenient. At the same time, the vertical overlapping height of the mounting seat 30 and the glass cup body 20 is reduced, which is conducive to expanding the vertical height of the first positioning groove 201, so as to expand the vertical detection range of the detection section 401, so that the detection lower limit of the detection plate 40 is closer to the bottom end of the glass cup body 20, and the detection range is wider.

[0115] The fixing method of the detection plate 40 and the positioning groove of the utility model is not limited to glue filling. In other preferred embodiments, the detection plate 40 can be fixed by double-sided tape or by a protective member 50 fixed on the outside of the glass cup body 20.

[0116] In addition, the present invention does not limit the formation of the first positioning groove 201 and the second positioning groove 301. For example, the first positioning groove 201 can be optionally formed by a depression on the outer side surface of the glass cup body 20, or by a convex rib on the outer side surface of the glass cup body 20.

[0117] In a preferred embodiment, in combination Figure 5 , Figure 6 , Figure 7 As shown, the bottom wall of the first positioning groove 201 and the bottom wall of the second positioning groove 301 are both planes. Specifically, the outer wall of the glass body 20 is provided with a plane 23, on which two vertical ribs 24 are protruding, and the two vertical ribs 24 and the plane 23 surround the first positioning groove 201.

[0118] More preferably, in combination Figure 3 As shown, the bottom wall of the first positioning groove 201 is a positioning plane, and the inner side wall of the glass cup body 20 is provided with an inner plane 25 corresponding to the position of the positioning plane.

[0119] Of course, it is understandable that in other embodiments, the inner wall of the glass cup body can also be a spoiler rib protruding inward, and the spoiler rib can be optionally V-shaped, C-shaped, etc. in cross section, or an inner plane is set on the spoiler rib.

[0120] In a preferred embodiment, the second positioning groove 301 is formed by an enclosing rib, which is U-shaped with an open upper end to enclose the second positioning groove 301 with the outer side surface of the mounting seat 30. The lower end of the signal processing section 402 abuts against the enclosing rib to be positioned in the second positioning groove 301, so that the installation height of the detection board 40 is accurate and the detection is more accurate.

[0121] The present invention does not limit the specific structure of the glass cup body 20. In a preferred embodiment, the cup mouth of the glass cup body 20 is provided with an annular rib protruding outward and a fixing seat fixedly mounted on the annular rib, and handles are provided on both sides of the fixing seat. The glass cup body 20 can be detachably mounted on the host 10. Preferably, the annular rib forms the upper end wall of the first positioning groove 201, and the upper end of the detection section 401 abuts against the annular rib to be positioned in the first positioning groove 201.

[0122] By setting an annular rib at the mouth of the glass cup body 20, the annular rib is used to fix the fixing seat and handles are formed on both sides of the fixing seat, so that the user can take and place the glass cup body 20 from bottom to top, which is labor-saving and convenient. The upper end wall of the first positioning groove 201 is formed by the annular rib, and the upper end of the detection section 401 abuts against the annular rib to be positioned in the first positioning groove 201. Therefore, the annular rib provides installation space for the fixing seat and the handle, making the structure reliable and stable. At the same time, the annular rib is also used to position the upper end of the detection section 401, improve the position of the detection plate 40 accurately, reduce installation errors and measurement errors, and achieve a compact structure.

[0123] Of course, it should be noted that in other embodiments, a capacitor electrode is provided on the inner side of the signal processing section, so that when the heating plate is bowl-shaped and the corresponding part of the mounting seat still needs to be detected for water level, the capacitor electrode on the signal processing section is used to realize low water level detection.

[0124] The utility model is not limited to the solution of integrating the detection plate, the glass cup body and the mounting seat through the glue filling layer. In other embodiments, optionally, Fig.11 As shown, the detection section and the signal processing section of the detection board 40 are both installed in the first positioning groove 201, so that the detection board fits the glass cup body as a whole, and the detection board and the glass cup body are only integrated through the glue layer, and the detection is accurate. Alternatively, a part (upper part) of the detection board is encapsulated in the positioning groove through the glue layer, and the lower part of the detection board is suspended relative to the positioning groove, so that the detection board and the glass cup body are integrated.

[0125] The food processor provided by the utility model can not only be the above-mentioned food processor that does not need to be washed by hands, but can also be a soymilk machine, a wall breaking machine, etc.

[0126] It should also be noted that the present invention does not limit the specific structure of the protective element. For example Figure 1 As shown, the protective member may be a decorative member. In fact, the protective member may also be a panel, etc.; of course, when the food processor adopts a soybean milk machine (such as Fig.12 When using a conventional wall-breaking machine (as shown) or an ordinary wall-breaking machine, the protective member 50 can be a handle. After the detection plate 40 and the glass cup body 20 are fixed together by a glue filling layer, the handle is fixed outside the glass cup body to hide the detection plate.

[0127] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0128] 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.

[0129] The above description is only an embodiment of the present invention and is not intended to limit the present invention.
