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, in which the mixing cup includes a glass with a handle and a water level detection structure arranged on the outer side of the glass, the water level detection structure includes a detection component fitted on the outer wall of the glass and a capacitive sensing plate connected to the detection component, the capacitive sensing plate is positioned at a preset position adjacent to the outer wall of the glass through the handle shell of the handle to realize the installation of the water level detection structure; moreover, the upper and lower ends of the handle are fixedly connected to the outer wall of the glass, and the detection component is located between the upper and lower ends, so that the handle has the function of protecting the detection component.

[0004] In the above technology, since the detection component and the sensor plate must be fixed by the handle, and the lower end of the handle is a certain distance away from the bottom of the cup body, there is no detection component in the area below the lower end of the handle, forming a detection blind area. The liquid in the cup corresponding to this part cannot be detected, causing the detection range of the detection component along the vertical direction of the cup body to be reduced, resulting in the inability to perform low water level detection and dry burning detection, and the scope of application is small.

[0005] There is also a patent application with application number 201610753199.4 that discloses an overflow prevention method and a food processor. A metal sheet is provided on the signal PCB board, and the metal sheet is arranged on the signal PCB board in a vertical direction, and the metal sheet is arranged at the bottom of the cup body. Before the food in the cup body is processed, the food in the cup body and the metal sheet at the bottom of the cup body form a capacitor. After the food is processed by the knife set or the electric heating element, the volume increases, and the capacitance value of the capacitor formed by the food and the metal sheet increases at the same time. The signal PCB board charges the metal sheet and generates a charge transfer signal on the signal PCB board. The signal PCB board transmits the charge transfer signal to the control circuit board, and the control circuit board determines the volume of the food in the cup body through the charge transfer signal.

[0006] However, in this solution, a blank area is set at the bottom of the PCB board (sensing board) to mount the processing chip or terminal blocks, etc., and the vertical installation area of ​​the metal sheet (detection component) on the PCB board is limited, which will still cause the vertical detection range along the cup body to be reduced, resulting in the inability to perform low water level detection and dry burning detection. At the same time, due to the fit between the PCB board and the cup body, the chip will be directly affected by the heat in the cup. As the liquid temperature rises, the chip temperature will rise rapidly, affecting the service life of the processing chip and posing the risk of detection failure.

[0007] Therefore, in the existing remote detection schemes, there is a problem of a small detection range of the detection plate. In addition, since the outer wall of the glass is a cylindrical shape with an arc, and the induction plate is a strip-shaped flat plate, the induction plate is directly positioned on the smooth glass through the handle shell, which will cause the induction plate to be difficult to position and slide relative to the glass body, resulting in inaccurate assembly position of the induction plate, affecting the detection accuracy; after the induction plate is installed in place, the edge of the induction plate cannot fit tightly with the glass, and it is easy to tilt up and cause the induction plate to move, and the positioning is still unreliable and the detection is inaccurate. In addition, the glass cups currently used for air detection are usually stretch-formed tubular glass cups. The wall thickness of the tubular 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 relying on other mounting structures such as the handle shell. On the one hand, this makes the assembly process complicated, the positioning of the sensor plate and the glass cup difficult, and the fit cannot be guaranteed, which affects the detection accuracy. On the other hand, if the detection plate and the cup body are not well positioned, there will be installation errors between the handle shell and the glass cup during the assembly process. When the detection plate is positioned using the handle shell, the relative position between the detection plate and the glass cup will be inaccurately assembled, the positioning of the detection plate will deviate, and there will be a deviation between the water level actually detected by the detection plate and the preset water level, resulting in inaccurate detection. Utility Model Content

[0008] The utility model provides a cup body component of a food processing machine, which not only solves the problem that the detection range of the detection plate is small, resulting in a low water level detection blind area in the cup body, but also further solves the technical problem that the positioning of the detection plate is difficult during the installation process, resulting in inaccurate detection.

[0009] The technical solution adopted by the utility model is:

[0010] The utility model provides a cup body component of a food processing machine, comprising a glass cup body, a detection plate for detecting liquid level in the air, and a mounting seat fixed at the lower part of the glass cup body, the cup body component comprising a positioning groove for positioning the detection plate, the positioning groove comprising a first positioning groove vertically arranged on the outer wall of the glass cup body and a second positioning groove extending from the first positioning groove to the outer wall of the mounting seat, the detection plate comprising a detection section for detecting liquid level and a signal processing section located below the detection section, the detection section and the signal processing section are respectively located in the first positioning groove and the second positioning groove.

[0011] The cup body assembly of the food processing machine provided by the utility model is provided with a positioning groove for positioning the detection plate, and the groove wall of the positioning groove limits the detection plate, so as to prevent the detection plate from sliding and shifting during the installation process of the detection plate and after the installation is in place. The detection plate is easy and reliable to position, which reduces the difficulty of assembly and further ensures 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, improves the fitting effect of the detection plate and the glass cup body, and further helps to reduce the spacing distance of the detection plate and improve the detection accuracy. The positioning groove includes a first positioning groove vertically arranged on the outer wall of the glass body and a second positioning groove extending from the first positioning groove to the outer wall of the mounting seat. The detection section and the signal processing section of the detection board are respectively located in the first positioning groove and the second positioning groove, so that the detection section of the detection board can correspond to the outer side of the glass body more fully and comprehensively, and the detection lower limit of the detection board is closer to the bottom of the glass body, so that the detection range of the detection board can be reasonably and fully matched according to the height of the glass body, 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 anti-overflow detection, expanding the vertical detection range of the detection board, and expanding the scope of application. By setting the mounting seat, the second positioning groove is located on the outer wall of the mounting seat, and the signal processing section is located in the second positioning groove. Therefore, the chip and the wiring terminal arranged in the signal processing section can play a certain role in heat insulation through the mounting seat, reduce the heat transfer from the glass body to the chip, avoid the chip and the wiring terminal from overheating and causing detection failure, and make the detection accurate and lasting.

[0012] In a preferred embodiment, there is an annular installation gap between the glass cup body and the mounting seat, which separates the first positioning groove and the second positioning groove. A shielding member for shielding the installation gap is provided in the positioning groove formed by the first positioning groove and the second positioning groove, and the detection plate is arranged on the outside of the shielding member.

[0013] 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. The mounting gap separates the first positioning groove and the second positioning groove. Therefore, a shielding member for shielding the mounting gap is provided in the positioning groove formed by the first positioning groove and the second positioning groove, and the detection plate is arranged on the outside of the shielding member. The shielding member can be used to shield or seal the mounting gap between the first positioning groove and the second positioning groove to prevent the water vapor passing through the mounting gap from damaging the detection plate or affecting the detection of the detection plate, and to prevent the mounting gap from storing water. The shielding member is used to support and limit the inner side of the detection plate to achieve reliable positioning of the detection plate.

[0014] In a preferred embodiment, a sealing ring is sleeved on the outer side of the installation gap, and the shielding member is a shielding portion arranged on the sealing ring.

[0015] A sealing ring is sleeved on the outside of the installation gap to effectively seal the installation gap, prevent water leakage from the glass cup body and dust from entering and affecting the detection of the detection board, so that the detection board can be effectively detected. The shielding member is a shielding part arranged on the sealing ring. The shielding member and the sealing ring 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 and the second positioning groove is docked, thereby improving the positioning and supporting effect of the detection board.

[0016] In a preferred embodiment, the sealing ring is provided with an opening, and the shielding member is connected to the opening and is recessed inwardly relative to the sealing ring;

[0017] Since the annular installation gap separates the first positioning groove and the second positioning groove, and the first positioning groove and the second positioning groove are recessed inward relative to the outer wall of the glass cup body, an opening is set in the sealing ring, and the shielding member is connected at the opening and recessed inward relative to the sealing ring; the connection position of the shielding member and the sealing ring can match the recessed shape of the positioning groove, so that the shielding member and the sealing ring can jointly fully seal the entire circle of the installation gap, thereby improving the sealing effect.

[0018] In a preferred embodiment, a clamping block for clamping the detection plate is provided on the sealing ring;

[0019] Alternatively, a connecting portion is provided on the sealing ring, and the connecting portion is located outside the shielding portion, and an installation opening for the signal processing section to pass through is formed between the shielding portion and the connecting portion.

[0020] By arranging a clamping block on the sealing ring, the detection board is clamped by the clamping block, so that while the installation gap between the first positioning groove and the second positioning groove is sealed by the covering member, the clamping block positions the outer side of the detection board, so that the detection board is pre-positioned in the positioning groove, and the positioning reliability of the detection board is further improved, so as to facilitate subsequent fixing operations such as glue filling or pressing on the detection board, greatly simplifying the assembly difficulty, and ensuring the installation accuracy and detection accuracy of the detection board at the same time.

[0021] By setting a connecting portion, a mounting opening is formed between the connecting portion and the shielding member. Therefore, the mounting opening is utilized to strengthen the positioning of the detection plate by the positioning groove, so that the detection plate can be positioned along the circumference and radial direction of the glass cup body. The positioning is more comprehensive, which facilitates subsequent fixing operations such as gluing or pressing the detection plate, greatly simplifies the difficulty of assembly, and ensures the installation accuracy and detection accuracy of the detection plate at the same time.

[0022] In a preferred embodiment, the shielding member includes a main body and an extension portion extending downward from the main body into the second positioning groove, and the extension portion isolates the second positioning groove from the signal processing section;

[0023] Alternatively, the shielding member defines a transition groove connecting the first positioning groove and the second positioning groove, and a retaining rib for limiting the detection plate is provided at an edge of the transition groove.

[0024] By setting the shielding member as a main body and an extension part, the second positioning groove and the signal processing section are isolated by using the extension part. Therefore, on the basis of using the mounting base to insulate the signal processing section, the extension part is used to further enhance the insulation effect, thereby forming good insulation protection for the chip, terminal blocks and other structures of the signal processing section, extending the service life and reducing the impact on the detection board.

[0025] The shielding member defines a transition groove connecting the first positioning groove and the second positioning groove, so that the first positioning groove and the second positioning groove are sealed and butted, and the detection plate is further limited by the retaining rib, so that the positioning is reliable.

[0026] In a preferred embodiment, the outer side of the detection board is encapsulated in the positioning groove by a glue potting layer;

[0027] On the basis of using the positioning groove to position and pre-install the detection board, the positioning groove is used to provide 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, liquid glue is filled on the outside of the detection board and in the positioning groove to seal the detection board, so that the outside of the detection board is encapsulated in the positioning groove by the glue injection layer to form a whole with the glass cup body. The fixation between the detection board and the glass cup body is completed in one step, eliminating the cumbersome assembly steps and assembly errors caused by indirect fixation through additional parts, greatly simplifying the assembly method, and while using the glue injection layer to fix the detection board, effective sealing of the detection board is achieved, ensuring that the detection board and the glass cup body are in close contact, effectively sealing the gap between the detection board and the glass cup body to prevent water vapor from entering, and reliably sealing, eliminating the need for separate setting of sealing film and other operations, while simplifying the assembly, ensuring the waterproofness of the detection board, avoiding the failure of the detection board due to water ingress and inaccurate detection, improving the detection accuracy and reliability, extending the service life, and simplifying the assembly and sealing methods. In addition, by providing a shielding member for shielding the installation gap in the positioning groove formed by the first positioning groove and the second positioning groove, a good operating basis is provided for the glue filling process, thereby preventing liquid glue from flowing into the installation gap, so that the glue filling and fixing of the detection board can be carried out smoothly.

[0028] In a preferred embodiment, the groove bottom wall of the first positioning groove and the groove bottom wall of the second positioning groove are arranged flush.

[0029] In general, the detection plate is flat on the side facing the glass cup body. Therefore, when the detection section and the signal processing section of the detection plate are located in different positioning grooves, the bottom wall of the first positioning groove and the bottom wall of the second positioning groove are set flush, which makes it easier to fit the detection plate and the positioning groove well, thereby improving the detection accuracy and positioning reliability.

[0030] In a preferred embodiment, the glass body includes a main body section and a contraction section that is indented inwardly relative to the main body section, and the mounting seat is sleeved and fixed on the outer periphery of the contraction section.

[0031] By providing a main section and a contraction section that is indented inward relative to the main section, the mounting seat is sleeved and fixed on the outer periphery of the contraction section, thereby achieving reliable fixation of the mounting seat of the glass cup body and simplifying the installation of the mounting seat; since the contraction section is indented inward, the outer wall of the mounting seat and the outer wall of the glass cup body can be nearly aligned after the mounting seat is fixed, thereby facilitating the alignment of the bottom walls of the first positioning groove and the second positioning groove, so as to facilitate the fitting of the detection plate as a whole with the bottom walls of the positioning groove, thereby improving the reliability of positioning and improving the sensitivity and accuracy of detection.

[0032] In a preferred embodiment, the lower end of the glass body is open and provided with an inner flange extending radially inward, a heating plate is provided above the inner flange, and the mounting seat is located below the glass body, and the heating plate and the mounting seat are fixedly connected to clamp the inner flange.

[0033] By setting an inner flange at the lower end of the glass cup body and using a heating plate and a mounting seat to fix the inner flange, the mounting seat is fixed to the lower end of the glass cup body, the fixation is reliable and the installation of the mounting seat is convenient. At the same time, the vertical overlapping height of the mounting seat and the glass cup body is reduced, which is conducive to expanding the vertical height of the first positioning groove, so as to expand the vertical detection range of the detection section, so that the detection lower limit of the detection plate is closer to the bottom end of the glass cup body, and the detection range is wider.

[0034] In a preferred embodiment, the cup mouth of the glass cup body 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.

[0035] An annular rib is arranged at the cup mouth of the glass cup body, 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 from bottom to top, and the operation is labor-saving and convenient.

[0036] In a preferred embodiment, the annular rib forms the upper end wall of the first positioning groove, and the upper end of the detection section abuts against the annular rib to be positioned in the first positioning groove.

[0037] The upper end wall of the first positioning groove is formed by the annular rib, and the upper end of the detection section abuts against the annular rib to be positioned in the first positioning groove. Therefore, the annular rib provides installation space for the fixed 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, improve the accuracy of the position of the detection plate, reduce installation errors and measurement errors, and achieve a compact structure.

[0056] like Figure 1-9 As shown, the utility model provides a cup body assembly of a food processing machine in one embodiment, the cup body assembly includes a glass cup body 20, a detection plate 40 for detecting liquid level in the air, and a mounting seat 30 fixed to the lower part of the glass cup body 20. The glass cup body 20 is preferably a high-boron glass cup formed by die-casting. The cup body assembly includes a positioning groove for positioning the detection plate 40, such as Figure 5-9 As shown, 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. 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 , 9As shown, the detection section 401 and the signal processing section 402 are located in the first positioning groove 201 and the second positioning groove 301 respectively.

[0057] In this embodiment, combined with Figure 1 As shown, the food processor is a food processor that does not need to be washed by hands, and 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.

[0058] 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.

[0059] The cup body assembly of the food processing machine provided in this 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.

[0060] 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.

[0061] In this embodiment, if Fig. 9 As 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] Preferably, the shielding member 60 may adopt any of the following implementation examples:

[0067] Implementation example 1, 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.

[0068] 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.

[0069] 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.

[0070] 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 liquid glue from flowing into the installation gap.

[0071] 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, liquid glue is filled on the outside of the detection board 40 and in the positioning groove to seal the detection board 40, so that the outside 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 additional components. 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.

[0072] 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.

[0073] 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.

[0074] In another preferred embodiment, Fig.10 As shown, a block 71 for holding the detection plate is provided on the sealing ring 70;

[0075] 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.

[0076] Implementation Example 2, combined with Fig.10The 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;

[0077] 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, and a retaining rib for limiting the detection plate is provided at the edge of the transition groove. The retaining rib can be the above-mentioned block 71 or the connecting portion 72.

[0078] 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.

[0079] Implementation example 3. In this implementation example, the mounting seat 30 is non-annular, and 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.

[0080] 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.

[0081] 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.

[0082] The fixing method of the detection plate 40 and the positioning groove of the utility model is not limited to the glue filling fixing in the embodiment 1. In other preferred embodiments, the detection plate 40 can be fixed by double-sided adhesive tape or by pressing and fixing the protection member 50 fixed on the outside of the glass cup body 20. The protection member can be a decorative member, a panel, etc.; or the protection member 50 can be a handle.

[0083] 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.

[0084] 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 positioning plane 23, on which two vertical ribs 24 are protruding, and the two vertical ribs 24 and the positioning plane 23 surround the first positioning groove 201, and a notch 26 is formed at the lower end of the first positioning groove 201.

[0085] More preferably, in combination Figure 3 As shown, the bottom wall of the first positioning groove 201 is a groove 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 groove plane.

[0086] 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.

[0087] 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 27 protruding outward and a fixing seat 28 fixedly mounted on the annular rib 27, and handles 29 are provided on both sides of the fixing seat 28. The glass cup body 20 can be detachably mounted on the host 10. Preferably, the annular rib 27 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 27 to be positioned in the first positioning groove 201.

[0088] By setting an annular rib 27 at the mouth of the glass cup body 20, the annular rib 27 is used to fix the fixing seat 28 and handles 29 are formed on both sides of the fixing seat 28, so that the user can take and place the glass cup body 20 from bottom to top, and the operation is labor-saving and convenient. The upper end wall of the first positioning groove 201 is formed by the annular rib 27, and the upper end of the detection section 401 abuts against the annular rib 27 to be positioned in the first positioning groove 201. Therefore, the annular rib 27 provides installation space for the fixing seat 28 and the handle 29, making the structure reliable and stable. At the same time, the annular rib 27 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.

[0089] 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, the portion corresponding to the mounting seat still needs to be tested for water level, and the capacitor electrode on the signal processing section is used to achieve low water level detection;

[0090] In addition, in other embodiments, Fig.11 As shown, optionally, 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 as a whole fits with the glass body and the detection is accurate.

[0091] The cup body assembly provided by the utility model can be applied not only to the above-mentioned food processing machine that does not require hand washing, but also can be selectively applied to soymilk machines, wall breaking machines, water boilers, tea bar machines, etc.
