Description

Technical Field

[0001] The utility model relates to the field of food processing, in particular to a food processing machine capable of heating and crushing food materials at the same time. Background Art

[0002] Existing food processors that can simultaneously achieve crushing and heating and boiling need to control the liquid level during the boiling process to prevent slurry or foam from overflowing. One existing method is to use a program to control heating, such as using an alternating heating control method of heating, stopping, and heating, and compressing the single heating time to prevent slurry from overflowing when heating is too long. However, this will result in low heating efficiency, extend the processing time of the food processor, and the slurry cannot be fully boiled and boiled, resulting in insufficient nutrition release of processed ingredients and poor taste.

[0003] Another existing method is to control the slurry by monitoring the liquid level. There are two specific implementation methods: one is contact overflow prevention electrode detection, in which an overflow prevention electrode is inserted into the cup body assembly of the processed food. When the slurry or foam rises and touches the overflow prevention electrode, the potential of the overflow prevention electrode is changed to achieve overflow prevention detection. However, this method can only trigger a signal when the foam rises to the overflow prevention electrode, and the height of the liquid level cannot be determined; furthermore, when there is slurry residue on the overflow prevention electrode, it is easy to trigger an error signal, and the leaking overflow prevention electrode increases the difficulty of cleaning for the user. There is also a non-contact overflow prevention detection method, in which a capacitive detection plate is set on the outside of the cup body assembly. When the slurry or foam changes height inside the cup body assembly, the detection plate generates a signal, which can avoid direct contact between the detection plate and the slurry, making it easy to clean and achieving comprehensive detection of water level and overflow prevention, with accurate detection.

[0004] However, the sticking assembly method of the detection plate in the above scheme easily causes the detection plate to be loosely attached to the cup body, and the distance between the water level in the cup body and the detection plate is far, resulting in inaccurate detection. At the same time, the detection plate is not firm and will be displaced in the axial direction, causing deviation from the preset position, affecting the accurate detection of the actual liquid level. Moreover, as the temperature of the cup body rises, the detection plate and the cup body assembly are not firmly attached, and there is also a risk of the detection plate falling off, causing detection failure.

[0005] An existing detection plate assembly method, such as the solution disclosed in CN201720526032.4: a capacitive water level detection structure is arranged on the outer side of the glass, including a detection plate fitted on the outer wall of the glass and a capacitive sensing plate connected to the detection plate, a handle shell is sleeved on the handle, the handle shell includes an arc-shaped cavity matching the handle and a mounting groove for embedding the capacitive sensing plate, the capacitive sensing plate is positioned at a preset station adjacent to the outer wall of the glass through the handle shell, and the handle shell provides precise positioning for the capacitive sensing plate, so that the capacitive sensing plate and the outer wall of the stirring cup firmly clamp the detection assembly. However, this installation method has high requirements for the glass itself, the installation structure is complex, and the capacitive sensing plate needs to be installed in the slot formed by the handle and the cup cover, which limits the size of the sensing plate itself and cannot achieve detection within a higher engineering range.

[0006] In order to achieve the purpose of noise reduction, the existing cup body assembly will install an outer cup outside the glass inner cup, and form a hollow isolation interlayer between the glass inner cup and the outer cup. In the prior art, the detection plate is generally pre-installed on the inner wall of the outer cup, and then the inner cup is inserted into the outer cup. However, during the research process, the applicant found that during the inner cup installation process, serious friction will occur between the inner cup and the detection plate, which will not only cause the detection plate to deflect and fail to ensure the accuracy of the detection, but also make it difficult to assemble the inner cup, affecting the assembly efficiency.

[0007] There is another installation method, which is to set a mounting structure on the outer wall of the inner cup, and pre-limit the detection plate on the mounting structure, so that the detection plate is installed in the outer cup together with the inner cup. This method will still cause the detection plate to shift with the inner cup, and there will be problems with inaccurate detection after installation. Furthermore, since it is difficult to form a mounting structure on the outer wall of the glass cup body, this installation method is limited to inner cups made of non-glass materials, such as ceramic cups. Since ceramic cup bodies have the defects of slow thermal conductivity and slow heat dissipation compared to glass cup bodies, when the detection board detects the anti-overflow signal, the control device controls the program to change to avoid stopping heating or reducing the heating power. However, there is still a risk of overflow due to the large thermal inertia of the liquid in the ceramic cup, and there is a problem of insensitive control. In addition, the ceramic cup body is heavy, which is inconvenient for users to hold.

[0008] Therefore, the applicant, while ensuring the existing glass inner cup and outer cup cooperate to reduce noise, improves heating efficiency and control sensitivity, while solving the problems of inaccurate detection of the detection plate, unstable and unreliable installation of the detection plate, and poor assembly efficiency. Summary of the invention

[0009] The present application provides a reliable food processing machine, which makes full use of the isolation interlayer formed by the existing outer cup and the glass inner cup, solves the problems of unstable assembly of the detection plate and the cup body assembly, complex assembly and poor efficiency, and inaccurate detection in the prior art, realizes accurate detection of the liquid level and ensures that the installation of the detection plate is reliable and will not shift during long-term use to affect the detection accuracy.

[0010] The utility model is achieved in the following ways: a reliable food processing machine, comprising a main machine, a cup body assembly installed on the main machine, a cup cover assembly covering the cup body assembly, and a detection plate for detecting the liquid level in the cup body assembly, wherein the cup body assembly comprises a glass inner cup, an outer cup and a cup base, the glass inner cup and the outer cup are sealed and connected to form an isolation interlayer between the glass inner cup and the outer cup, the detection plate is strip-shaped and vertically arranged in the isolation interlayer, the cup base closes the lower opening of the isolation interlayer and abuts against the lower end of the detection plate to push the detection plate to fit the outer side wall of the glass inner cup.

[0011] Preferably, a guide structure arranged along the axial direction is provided in the isolation interlayer, and the detection plate is inserted into the isolation interlayer along the guide structure through the lower opening.

[0012] Preferably, the guide structure includes a guide groove arranged on the inner wall of the outer cup, and a limiting rib is also provided in the guide groove. When the detection plate is installed in place, the limiting rib contacts the back of the detection plate to make the detection plate fit with the outer wall of the glass inner cup.

[0013] Preferably, a mounting platform is provided on the inner wall of the outer cup, and the detection plate is arranged on the mounting platform. When the outer cup is sleeved on the glass inner cup, the detection plate fits with the outer wall of the glass inner cup.

[0014] Preferably, a connecting portion is provided at the bottom of the glass inner cup, and the cup base is sealedly connected to the glass inner cup via the connecting portion, and the cup base is also provided with a limiting portion abutting against the lower end of the detection plate.

[0015] Preferably, the limiting portion is provided with an adjusting member which can move in the axial direction, and the adjusting member pushes the detection plate to move in the axial direction.

[0016] Preferably, an isolating piece is disposed on the outer cover of the detection plate, and the isolating piece is elastic and has an interference fit with the isolation interlayer, so that the detection plate is clamped between the outer cup and the glass inner cup.

[0017] Preferably, the gap of the isolation interlayer gradually increases from top to bottom, the detection plate is arranged in contact with the outer wall of the glass inner cup, and the gap between the detection plate and the outer wall of the glass inner cup is not greater than a preset value.

[0018] Preferably, the outer cup is sealed and combined with the upper outer side wall of the glass inner cup, and the cup base is sealed and connected to the outer cup and the glass inner cup respectively to form a closed isolation interlayer.

[0019] Preferably, the outer side wall of the outer cup is also provided with a handle, and the detection plate is arranged at a position of the isolation interlayer corresponding to the handle.

[0020] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0021] 1. By setting a detection plate for detecting the liquid level and foam height in the cup body assembly, the detection plate is arranged in a strip shape and is arranged vertically in the isolation interlayer and is in contact with the outer wall of the glass inner cup. The liquid level change in the cup body is monitored in real time, and the position and rising rate of the liquid level are detected in real time. When the slurry generates foam, the position and rate of the foam rise can be accurately determined, and the water level height of the liquid level in the cup body assembly and the anti-overflow signal are comprehensively detected and determined, and then fed back to the program control module of the heater to achieve precise heating control and avoid overflow of slurry or foam, that is, the slurry can be fully boiled during the pulping process, thereby improving the nutrient release and taste of the slurry, and shortening the pulping cycle by extending the single heating time to improve the pulping efficiency. The detection board is directly arranged in the isolation interlayer formed by the cup body assembly. The detection board is simple and convenient to install, and the closed isolation interlayer can also protect the detection board to prevent the detection from being affected by media such as fluids, thereby ensuring the accuracy of the detection of the detection board; the detection board can be inserted into the isolation interlayer and reach a preset position to ensure that the detection of the liquid level by the detection board is in a preset state, thereby improving the reliability of control; and the cup base is used to close the lower opening of the isolation interlayer and abut against the lower end of the detection board, thereby ensuring that the detection board is in a preset position, preventing the detection board from being displaced and affecting the detection, and also promoting the detection board to fit the outer wall of the glass inner cup, thereby improving the stability and reliability of the detection board. It should be noted that the purpose of the abutment between the cup base and the lower end of the detection plate is to be able to exert force on the detection plate to push the detection plate to fit the glass inner cup and improve the stability of the detection. The cup base and the detection plate can be in direct contact or indirect contact by setting a medium between the cup base and the detection plate. For example, a shock-absorbing pad is set between the cup base and the detection plate, or a gasket for adjusting the axial height position of the detection plate is set between the cup base and the detection plate. Both of these can achieve the purpose of using the cup base to limit the lower end of the detection plate in this application to improve the installation reliability of the detection plate. Such schemes all belong to the protection content of this application.

[0022] 2. By setting the guide structure, on the one hand, it can limit the detection plate, so that the detection plate is in a controllable state when inserted into the isolation interlayer, ensuring that the detection plate can be installed to the preset position; on the other hand, the guide structure can also ensure that the structure of the detection plate is stable and reliable after it is installed in place, and will not cause axial or circumferential displacement in the isolation interlayer, thereby ensuring that the detection plate can accurately match the preset liquid level height of the cup body assembly to perform accurate water level or overflow prevention detection. The detection plate only needs to be inserted into the isolation interlayer from the lower opening of the isolation interlayer formed by the inner and outer glass cups to achieve accurate installation, and then the lower end of the detection piece is limited by the cup base, which is simple and convenient to install.

[0023] 3. Usually, the inner cup made of glass is not used to form a complex structure. A guide groove is set on the inner wall of the outer cup to form the guide structure. The outer cup made of other materials such as plastic can be used to form the guide groove to facilitate the installation and positioning of the detection board and ensure the reliable installation of the detection board. In order to ensure the reliability of the detection board in identifying the liquid level, a plurality of detection units are usually set on the detection board, each detection unit has a certain area to generate a changing electrical signal. In order to identify the change in height of the liquid level, the detection board needs to increase the horizontal size as much as possible, that is, the width of the detection board is as large as possible within the possible range, and it is necessary to ensure that the detection board fits the outer wall of the glass inner cup as much as possible in width, so as to accurately identify and determine the liquid level of the glass inner cup. Therefore, a limit rib is set in the guide groove, and the limit rib contacts the back of the detection board to push the detection unit under the detection board to fit with the glass inner cup, so as to avoid the detection board from changing in size in the suspended state and affecting the accuracy of the detection board.

[0024] 4. For different installation methods of the cup body assembly, for example, the outer cup is sleeved on the outside of the glass inner cup, the glass inner cup is inserted into the outer cup and sealed to the outer cup, and a sealing structure can be provided at the connection between the glass inner cup and the outer cup. Therefore, a mounting platform can be provided on the inner wall of the outer cup. When assembling the cup body assembly, the detection plate is first assembled on the mounting platform, and then the outer cup is sleeved on the outside of the glass inner cup. The mounting platform can push the detection plate to fit with the outer wall of the glass inner cup to achieve the detection function, and then a cup base is provided at the bottom of the outer cup and the glass inner cup, and the cup base is used to fix the outer cup and the glass inner cup. At the same time, the cup base can also abut against the bottom end of the detection plate to limit the detection plate in the axial direction, thereby ensuring that the detection plate is in a reliable preset position.

[0025] 5. A connection part is directly set at the bottom of the glass inner cup, and the cup base is directly fixedly connected to the glass inner cup through the connection part. On the one hand, the bottom opening of the glass inner cup can be directly closed to form a processing space for crushing processing in the glass inner cup. On the other hand, the cup base is connected to the glass inner cup and limits the detection plate at the same time, reducing the installation path, making the installation position between the detection plate and the glass inner cup more accurate and the detection more reliable. A limit part is further set on the cup base to abut the lower end of the detection plate, and the limit part can limit the detection plate more reliably.

[0026] 6. Although the cup base can limit the lower end of the detection plate to ensure that the detection plate is in the preset installation position, there will be dimensional tolerances for each accessory for different cup body components. Therefore, it is necessary to fine-tune the size of the installed detection plate to better provide the detection accuracy of the detection plate. An adjustment member that can move axially is set at the limit part. When the detection plate and the cup base are installed in place, the adjustment member can be used to fine-tune the axial position of the detection plate to ensure more accurate detection of the detection plate.

[0027] 7. By arranging an elastic isolation piece on the outer surface of the detection plate, the isolation piece is used to directly clamp the detection plate between the outer cup and the glass inner cup. During installation, the outer cup and the glass inner cup can be assembled first, and then the detection plate with the isolation piece can be inserted into the isolation interlayer. The elasticity of the isolation piece can be used to position the detection plate in the isolation interlayer, thereby ensuring that the detection plate can realize the detection function. The cup base can be further used to limit the detection plate to enhance the positioning effect.

[0028] 8. Generally speaking, the cup body will be set in a tapered shape to utilize the processing and manufacturing of the cup body. Therefore, no matter the glass inner cup or the outer cup, it usually has a certain inclination angle. Relatively speaking, the glass material requires a larger inclination angle, so that an isolation interlayer with a gap gradually increasing from top to bottom is formed between the outer cup and the glass inner cup, that is, from the cross-section, the isolation interlayer forms an angle that is small at the top and large at the bottom. The larger size at the bottom is conducive to the insertion of the detection plate into the isolation interlayer through the lower opening of the isolation interlayer, and the smaller size at the top is conducive to clamping and limiting the detection plate. For example, when an elastic isolation piece is arranged outside the detection plate, the isolation piece and the detection plate are jointly set to a cross-sectional size similar to that of the isolation interlayer, which is small at the top and large at the bottom. In this way, when installing the isolation piece and the detection plate, the small size at the top of the isolation piece first matches the large size at the bottom of the isolation interlayer, so as to facilitate the insertion and installation of the isolation piece and the detection plate. When installed in place, the isolation piece and the isolation interlayer have an interference fit to fix the detection plate in place, and then the bottom end of the detection plate is limited by the cup base to achieve reliable positioning of the detection plate. Furthermore, in order to ensure that the detection plate can accurately detect the liquid level, it is necessary to minimize the gap between the detection plate and the glass inner cup, and preferably keep the gap between the detection plate and the glass inner cup unchanged from top to bottom. However, since the outer wall of the glass inner cup is usually not arranged in a straight line like the detection plate, it is only necessary to fit the detection plate to the outer wall of the glass inner cup, and the gap between the detection plate and the outer wall of the glass inner cup should not be greater than a preset value. The preset value refers to the minimum value at which the detection plate can accurately detect the liquid level in the glass inner cup. The gap between the two only needs to be within this range, and there is no need to particularly pursue the gap between the detection plate and the glass inner cup to remain unchanged from top to bottom.

[0029] 9. The outer wall of the outer cup and the inner glass cup are sealed at the upper end, and further, the cup base is sealed at the bottom end with the inner glass cup and the outer cup, respectively. In this way, the outer cup, the inner glass cup and the cup base form a closed isolation interlayer. The detection board is set in the closed isolation interlayer, which can prevent the overflow of fluid or external dust from affecting the normal detection of the detection board, and there is no need to set a seal on the detection board itself. At the same time, the closed isolation interlayer can more effectively seal the noise generated in the cup body assembly, thereby achieving efficient noise reduction of the food processing machine under the premise of ensuring accurate detection of the detection board.

[0030] 10. A handle is provided on the outer wall of the outer cup to facilitate the holding operation of the cup body assembly, and the detection board is further provided at the position of the handle corresponding to the isolation interlayer. On the one hand, a corresponding mounting structure needs to be provided at the handle position, and a structure for installing the detection board is provided on the inner wall of the outer cup; on the other hand, in order to facilitate the observation of the processing conditions in the cup body assembly, the outer cup will be provided as a transparent part, so that the transparent outer cup plus the glass inner cup can conveniently observe the processing of the food, but the detection board cannot usually be provided in a transparent part. It is provided at the position corresponding to the handle, and the corresponding mounting structure and the detection board can be shielded by the handle to prevent the detection board from affecting the appearance of the cup body assembly. Of course, the detection board can also be superimposed with other functions, for example, the detection board is provided to present different colors at different temperatures, or the detection board is provided with different indicator lights, etc. At this time, the detection board can also be provided in a prominent position of the cup body assembly, thereby presenting the corresponding functional module, without having to be hidden in the handle position.

[0053] The utility model discloses a reliable food processing machine, such as Figure 1-13As shown, the food processor includes a host, a cup assembly, a cup cover assembly and a detection board. The cup assembly is installed on the host. A crushing knife for crushing and a heating assembly for heating and boiling ingredients are provided in the cup assembly. The host provides power for the cup assembly to drive the crushing knife to rotate. Of course, a power module can also be directly provided in the cup assembly to drive the crushing knife to rotate; or, the heating assembly can also be provided on the host to heat the ingredients in the cup assembly by indirect heating or contact heating. A cup cover assembly is provided at the upper opening of the cup assembly. When working, the cup cover assembly blocks the opening of the cup assembly to prevent the slurry from splashing. When the food processor is working, it is necessary to determine the height of the liquid level in the cup assembly. At the same time, during the boiling process, it is necessary to determine the height of the liquid level of the slurry or the height of the foam generated by the slurry in real time to avoid adding too much fluid before working and the foam overflowing the cup assembly during boiling. In order to better realize the detection, a detection board is further provided to detect the liquid level in the cup assembly. At the same time, in order to better reduce the noise generated by the crushing knife in the cup body assembly during the processing, the cup body assembly of the utility model is configured as a double layer, including a glass inner cup, an outer cup and a cup base, an isolation interlayer is formed between the glass inner cup and the outer cup, and the cup base closes the lower opening of the isolation interlayer. The isolation interlayer formed between the glass inner cup and the outer cup is used to set the detection board in the isolation interlayer. In this way, the existing structure of the cup body assembly is fully utilized without adding a special installation structure for installing the detection board, especially a sealing arrangement in the isolation interlayer, and there is no need to specially set a seal for the detection board. The detection plate is installed in the cup body assembly through the lower opening of the isolation interlayer, and the lower end of the detection plate is abutted against the cup base. The cup base is used to push the detection plate to fit the outer wall of the glass inner cup, so that the detection plate can accurately detect the liquid level and foam in the glass inner cup, and feed back the detection signal to the control module of the food processor. With such an arrangement, the food processor adds a double-layer cup structure to achieve the purpose of noise reduction. At the same time, a detection plate that does not need to be inserted into the cup body assembly is added to realize the detection of liquid level and foam of the food processor. The detection plate is arranged in the isolation interlayer, which realizes the purpose of non-contact "air-to-air" detection and achieves the effect of air-to-air overflow prevention. The structure is simple and ensures that the detection plate fits reliably with the glass inner cup. The cup base is used to ensure that the detection plate is in a reliable preset position, thereby providing a food processor that can further realize stable and reliable detection and judgment on the basis of effective noise reduction.

[0054] Embodiment 1.

[0055] As a first embodiment of a reliable food processing machine described in the utility model, Figure 1 , 2As shown, the food processor includes a host 100, a cup assembly 200, a cup cover assembly 300 and a detection board 400. The cup assembly 200 is mounted on the host 100, the cup cover assembly 300 covers the upper opening of the cup assembly 200 to shield the cup assembly 200, and the detection board 400 is used to detect the liquid level in the cup assembly 200, including the height position of the liquid in the cup assembly 200 and the height position of the foam generated when the liquid is heated and boiled.

[0056] The cup assembly 200 includes a glass inner cup 210, an outer cup 220 and a cup base 230. The glass inner cup 210 is inserted into the outer cup 220 and sealed to form an isolation interlayer 201 between the glass inner cup 210 and the outer cup 220. The isolation interlayer 201 can isolate the noise generated in the glass inner cup 210 to reduce the noise in the cup assembly 200. The detection plate 400 is strip-shaped and is vertically arranged in the isolation interlayer 201, and the detection plate 400 is in contact with the glass inner cup 210. It should be noted that the detection plate 400 mainly relies on the detection unit on the detection plate 400 to detect the liquid level in the glass inner cup. When there is liquid in the glass inner cup, when the liquid level changes, and when the foam changes, the detection unit will generate an electrical signal to detect the liquid level. However, the detection plate itself needs to be set up, usually in a hard plate shape, and the cross-section of the glass inner cup is usually circular. Therefore, the detection plate cannot be completely fitted with the outer wall of the glass inner cup, but only tangentially or partially fit. As long as the distance between the detection plate and the outer wall of the glass inner cup is within a preset range, that is, the detection plate and the liquid in the glass inner cup are within a preset distance, the detection function can be achieved. Therefore, the fitting here is not limited to full contact between the detection plate and the glass inner cup, but refers to tangential contact, or partial contact, or "non-contact" fitting with a close distance. It is only necessary to ensure that the detection plate can normally realize the detection function, which is also the advantage of setting a non-inserting detection plate.

[0057] A lower seal 501 is provided between the cup base 230 and the glass inner cup 210, and the lower seal 501 is also sealed and connected to the outer cup 220. The cup base 230 closes the lower opening of the isolation interlayer 201 through the lower seal 501 and abuts against the lower end of the detection plate 400, positioning the detection plate 400 to a preset position. Directly inserting the detection plate 400 from the lower opening of the isolation interlayer 201 into the isolation interlayer 400 will cause the detection plate 400 to shift in the axial direction. When it cannot be in the preset position, it will affect the detection plate's accurate determination of the liquid level in the glass inner cup. The detection plate is positioned by using the cup base, and the detection plate can be limited in the axial direction, circumferential direction, radial direction, etc., to ensure that the detection plate is always in the preset position, and to ensure that the detection state of the detection is stable and reliable. At the same time, the cup base can also always push the detection plate to fit the outer wall of the glass inner cup. It should be noted that the cup base abuts against the lower end of the detection plate, which does not limit the direct contact between the two. For example, the lower seal is arranged between the cup base and the detection plate, and the cup base indirectly pushes the detection plate to a preset position through the lower seal. Of course, the cup base can also directly contact the detection plate, as long as the cup base can realize the function of pushing and limiting the detection plate.

[0058] Embodiment 2.

[0059] As a second embodiment of a reliable food processing machine according to the utility model, Figure 3 , 4 As shown, compared with the first embodiment, the cup base is further provided with a limit part and an adjusting part to achieve fine adjustment of the position of the detection plate. It should be noted that the specific first embodiment and the second embodiment described separately do not mean that the cases of the two embodiments are completely independent of each other, but are only for the purpose of specifically illustrating two preferred technical solutions, and the technical features and technical solutions of the two embodiments are common and can be used for reference.

[0060] The glass inner cup 210 includes an upper section, a middle section and a lower section. The middle section shrinks relative to the upper section to form a step on the outer wall. The outer cup 220 is sleeved outside the glass inner cup 210 and abuts against the step. An upper sealing member 502 is provided between the outer cup 220 and the glass inner cup 210. A connecting portion 211 is provided at the lower section of the glass inner cup 210. The cup base 230 is sealed and connected to the glass inner cup 210 via the connecting portion 211. A sealing member is provided at the bottom end of the glass inner cup 210 between the cup base 230 and the glass inner cup 210, and a first sealing member 503 is provided on the outer side of the glass inner cup 230.

[0061] The cup base 230 is also provided with a limit portion 231 abutting against the lower end of the detection plate 400, and the limit portion 231 abuts against the detection plate 400 to push the detection plate 400 to a preset position. Further, the limit portion 231 is also provided with an adjustment member 232, and the adjustment member 232 can move along the axial direction of the cup body assembly 200 and abut against the lower end of the detection plate 400. When assembling the cup body assembly, the outer cup 220 is sleeved by the lower end of the glass inner cup 210 and abuts against the stage of the glass inner cup 210, and the detection plate 400 is installed in the isolation interlayer formed between the glass inner cup 210 and the outer cup 220, and the cup base 230 is installed at the bottom of the outer cup 220 and the glass inner cup 210 and closes the isolation interlayer 201 to achieve the installation and positioning of the detection plate 400. However, there will be dimensional tolerances for different cup body assemblies, so that for the same installation structure, there will be height differences in the axial direction of the detection plate 400, which will affect the detection accuracy of the detection plate 400; the adjustment member 232 is further provided. When the assembly is completed, the adjustment member 232 can be used to fine-tune the axial installation size of the detection plate 400 to compensate for the installation size tolerance of the cup body assembly, so that the detection of the detection plate 400 is more accurate, ensuring that the food processor works stably and reliably.

[0062] Embodiment three.

[0063] As a third embodiment of a reliable food processing machine according to the utility model, Figure 5 , 6 As shown, compared with the first embodiment, the outer cup is further provided with a guide structure to achieve installation limit of the detection plate. It should be noted that the multiple different embodiments described separately do not mean that the cases of the multiple embodiments are completely independent of each other, but are only for the purpose of specifically illustrating two preferred technical solutions, and the technical features and technical solutions of the multiple embodiments are common and can be used for reference.

[0064] like Figure 5 , 6 As shown, the cup assembly 200 includes a glass inner cup 210 and an outer cup 220, an isolation interlayer 201 is formed between the glass inner cup 210 and the outer cup 220, and the detection plate 400 is inserted from bottom to top into the isolation interlayer 201. A guide structure arranged along the axial direction is provided in the isolation interlayer 201, and the detection plate 400 can be inserted into the isolation interlayer 201 from the lower opening of the isolation interlayer 201 by the guide structure.

[0065] Preferably, the guide structure includes a guide rib 222 disposed on the inner side wall of the outer cup 220, two guide ribs 222 are disposed on the inner side wall of the outer cup 220 along the circumferential direction, a guide groove 223 is disposed between the two guide ribs 222, and the detection board 400 is inserted into the guide groove 223. In this way, the installation of the detection board 400 is facilitated, and the detection board 400 can be reliably attached to the outer side wall of the glass inner cup 210 by relying on the guide groove 223, so as to ensure that the detection of the detection board 400 is accurate and reliable.

[0066] Preferably, the guide structure further includes a limiting rib 224 disposed on the inner wall of the outer cup 220, and the limiting rib 224 is disposed inside the guide groove 223. When the detection plate 400 is installed in place, the limiting rib 224 contacts the back of the detection plate 400 to push the detection plate to fit with the outer wall of the glass inner cup 210. Generally speaking, the detection plate 400 has a certain width in the horizontal direction to ensure that the detection unit used for detection has a certain area. When the detection plate 400 is installed in the guide groove 223, the front side with the detection unit needs to fit with the outer wall of the glass inner cup 210. The detection plate 400 may be affected by the glass inner cup and deformed, thereby affecting the reliability of the detection. The limiting rib 224 is used to abut on the back of the detection plate, which effectively ensures that the structure of the detection plate is stable and reliable, and improves the detection accuracy.

[0067] Preferably, the outer wall of the outer cup 220 is further provided with a handle 221, and the handle 221 is arranged on the outer side of the outer cup 220, and the handle 221 is integrally arranged with the outer cup 220 or the handle 221 is assembled on the outer cup 220, and the detection plate 400 is arranged at the position of the isolation interlayer 201 corresponding to the handle 221. In this way, when the outer cup 220 is set to a transparent material, the processing status inside the cup body assembly can be observed through the outer cup 220 and the glass inner cup 210, and the detection plate is arranged at the position corresponding to the handle, and the detection plate 400 can be shielded by the handle to prevent the detection plate 400 from leaking out and affecting the appearance of the cup body assembly 200.

[0068] It can be understood that the guide structure can also be arranged on the outer wall of the glass inner cup; or, the guide structure is separately arranged in the isolation interlayer, assembled with the glass inner cup or outer cup, and used to install the detection board.

[0069] It can be understood that the guide structure can also be set as multiple groups of limiting protrusions with limiting functions, and the detection plate cooperates with the multiple groups of limiting protrusions in sequence to achieve limiting installation.

[0070] It can be understood that the interior of the guide groove is filled with a solid substance, and the back side of the detection plate is directly in contact with the inner wall of the guide groove.

[0071] It is understandable that a shock absorbing member may also be provided between the detection plate and the guide structure.

[0072] It can be understood that the detection board can also be arranged at a corresponding position according to different needs. For example, a display device can be arranged at the back of the detection board. In this way, the detection board is arranged at a position that is easy for the user to observe.

[0073] Embodiment 4.

[0074] As a fourth embodiment of a reliable food processing machine according to the utility model, Figure 7-9 As shown, compared with the first embodiment, the gap of the isolation interlayer gradually increases from top to bottom, and the detection board is inserted into the isolation interlayer through the lower opening of the isolation interlayer to achieve installation limit of the detection board. It should be noted that the multiple different embodiments described separately do not mean that the individual cases of the multiple embodiments are completely independent of each other, but are only for the purpose of specifically illustrating two preferred technical solutions, and the technical features and technical solutions of the multiple embodiments are common and can be used for reference.

[0075] like Figure 7-9 As shown, during the manufacturing process of the glass inner cup 210 and the outer cup 220, a certain tilt angle needs to be set to facilitate production. Generally speaking, the glass inner cup 210 made of glass needs to be set at a larger tilt angle, and the outer cup 220 can be made of materials such as plastic, and only needs to be set at a smaller tilt angle. Therefore, when the outer cup 220 is sleeved on the outside of the glass inner cup 210, the isolation interlayer 201 formed between the two presents a gap that gradually increases from top to bottom. The detection plate 400 is easy to insert into the isolation interlayer when inserted from the lower opening with a larger opening. When the detection plate 400 reaches the preset position, the isolation interlayer with a narrowed upper portion can clamp and position the detection plate 400, and then abut at the lower end through the cup base 230 at the bottom, so that the detection plate 400 and the outer wall of the glass inner cup 210 are stably and reliably fitted.

[0076] Preferably, the detection board 400 is provided with an isolating member 401, wherein the isolating member 401 is configured to be formed with a narrow upper part and a wide lower part in the axial direction similar to the isolating interlayer, so that when the detection board 400 is sleeved by the isolating member 401 and inserted into the isolating interlayer 201, there is a large gap between the isolating member 401 with a narrow upper part and the isolating interlayer 201, which is easy to install the isolating member 401 and the detection board 400; when the isolating member 401 is installed in place, the isolating member 401 and the isolating interlayer 201 of the same shape are closely matched at the upper end and the lower end, so that the detection board 400 and the glass inner cup 210 are stably and reliably fitted. Then, the cup base 230 is abutted against the detection board 400 or the isolating member 401 at the bottom to prevent the detection board 400 from sliding downward from the lower opening, so as to ensure that the detection board 400 is in a preset position.

[0077] It should be noted that when the detection plate is installed in place, the detection plate 400 is preferably tightly fitted against the glass inner cup 210, but in actual products, the glass inner cup 210 is usually a cone with a circular cross-section, and is usually provided with multiple sections of variable diameters with different functions, while the detection plate 400 is a flat plate that is easy to produce, which means that the detection plate 400 will not completely fit against the outer wall of the glass inner cup 210. In order to ensure accurate and reliable detection, usually the distance between the detection plate and the glass inner cup 210 only needs to be within a preset range, that is, the gap between the detection plate 400 and the glass inner cup 210 from the upper end to the lower end only needs to be less than the preset value to ensure that the detection of the detection plate is reliable and accurate. Therefore, when the detection plate 400 with the isolation member 401 is installed with the isolation interlayer 201, the isolation member 401 located on the back side of the detection plate 400 is set to a thickness that is narrow at the top and wide at the bottom, and the isolation member 401 located on the front side of the detection plate 400 is set to have the same thickness, so that when the detection plate 400 is attached to the glass inner cup 210 through the isolation member 401, the gap between the detection plate 400 and the outer wall of the glass inner cup 210 is not greater than the preset value.

[0078] Embodiment five.

[0079] As a fifth embodiment of a reliable food processing machine according to the utility model, Figure 10-12 As shown, compared with the first embodiment, the inner wall of the outer cup is further provided with a mounting platform, and the detection plate is arranged on the mounting platform to achieve installation limit of the detection plate. It should be noted that the multiple different embodiments described separately do not mean that the cases of the multiple embodiments are completely independent of each other, but are only for the purpose of specifically illustrating two preferred technical solutions, and the technical features and technical solutions of the multiple embodiments are common and can be used for reference.

[0080] like Figure 10-12As shown, the inner side wall of the outer cup 220 is provided with a mounting platform 225, and the outer cover of the detection plate 400 is provided with an isolating member 410, and the isolating member 410 is provided with a slot 411, and the detection plate 400 is clamped in the slot 411. The mounting platform 225 is provided with a limiting column 226, and an adjusting screw 227 is provided at the limiting column 226. The detection plate 400 and the isolating member 410 are fixed to the mounting platform 225 by the adjusting screw 227, and at the same time, the adjusting screw 227 can be adjusted in the radial direction. When the detection plate 400 is installed with the glass inner cup 210, the adjusting screw 227 can push the detection plate 400 in the radial direction to strengthen the fitting effect with the glass inner cup 210.

[0081] Preferably, the isolating member 410 is provided with an isolating cover plate 412, the detection plate 400 is installed in the card slot 411 through the isolating cover plate 412, the isolating cover plate 412 is provided with a first buckle 413, the isolating member 410 is provided with a second buckle 414, and the isolating cover plate 412 is mutually engaged through the first buckle 413 and the second buckle 414. In this way, the detection plate 400 has a better sealing effect.

[0082] The detection plate 400 is set on the inner side of the outer cup 220 through the mounting platform 225, and then assembled with the glass inner cup 210, so that the detection plate 400 is attached to the outer wall of the glass inner cup 210, and the detection plate 400 is limited at the bottom by the cup base 230. The detection plate 400 can also be adjusted radially by the adjusting screws 227, so that the detection plate and the glass inner cup 210 are stably and reliably attached, and the detection is accurate.

[0083] It can be understood that the mounting platform can also be set on the outer side wall of the glass inner cup, and the outer cup is then mounted after the detection plate and the glass inner cup are installed, and the cup base is used to abut and limit the bottom.

[0084] Description of the structure of the general detection board.

[0085] As a reliable universal detection plate structure of a food processing machine of the utility model, Fig.13 As shown, this description only specifically describes a preferred universal detection board, and does not limit all detection boards in the utility model to adopt this solution.

[0086] As shown in the figure, the detection plate 400 is a plate-shaped plate extending in the axial direction and having a height. The detection plate 400 includes a first liquid level detection area 421 and a second liquid level detection area 422. Generally speaking, the first liquid level detection area 421 is located at the lower side of the second liquid level detection area 422. The first liquid level detection area 421 located below the M line is used to detect the liquid level area below the cup body assembly, and the second liquid level detection area 422 located below the M line is used to detect the foam area above the cup body assembly. The liquid level of the cup body assembly located in the first liquid level detection area 421 is usually liquid, which is more sensitive when the liquid level changes. Therefore, the first detection sheet 431 of the first liquid level detection area 421 is set to a smaller area and is stacked in multiple layers in the vertical direction; the cup body assembly located in the second liquid level detection area 422 is usually boiling bubbles or foam, which is less affected by the change of the medium. The second liquid level detection area 422 is provided with a second detection sheet 432 with a larger area, which can quickly and accurately realize the detection.

[0087] It should be noted that the food processor described in the present invention is not limited to products with a crushing function. Other types such as water kettles and health pots that only have a heating function and only need to heat the liquid are all covered within the protection scope of the present invention.

[0088] The above is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the present invention are covered by the scope of the claims of the present application and will not be listed one by one here.
