Description

Technical Field

[0001] The utility model belongs to the technical field of heating devices, and in particular relates to a liquid heater with remote detection. Background Art

[0002] Existing liquid heating devices, such as soymilk machines, usually need to be equipped with 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 anti-overflow electrode is installed on the cup cover, and the cup cover and the cup body are electrically coupled. When the boiling slurry overflows, it contacts the anti-overflow electrode, and the potential of the anti-overflow electrode is changed to realize the anti-overflow detection. This detection method is easy to cause the slurry to adhere to the outside of the anti-overflow electrode, which is inconvenient to clean. In addition, when the user cleans the cup cover, there may be a risk of water entering the cup cover, causing damage to the circuit of the anti-overflow electrode;

[0003] Another anti-overflow detection method is remote detection. A detection board is set on the outside of an insulating glass cup body, and a capacitor electrode is attached to the detection board. The capacitance of the detection board changes with the volume of the liquid in the glass cup body, thereby realizing remote liquid level detection or anti-overflow detection without contacting the liquid.

[0004] For example, the applicant previously developed a food processing machine that fixes a detection plate on the outer wall of a glass cup body. By fixing a protective piece on the outer wall of the glass cup body, the detection plate is installed in the installation space formed between the protective piece and the glass cup body to achieve air detection.

[0005] However, the existing remote detection method requires the detection plate and the glass cup body to be fixed as one, and in some food processing machines where the cup body is detachable from the main machine, since the user needs to remove the cup body from the main machine for rinsing, if the seal of the detection plate is unreliable, during the cleaning of the cup body, there may be a risk of water or water vapor entering the installation space and damaging the detection plate, affecting the effective and accurate detection of the detection plate; for some food processing machines with multiple cup bodies, although one main machine can cooperate with multiple different cup bodies to realize a variety of processing functions, in order to realize overflow prevention detection of multiple functions, it is necessary to install corresponding detection plates on the outside of multiple cup bodies with corresponding functions to realize overflow prevention detection, which makes the overall structure complicated and the cost increased. Utility Model Content

[0006] The utility model provides a liquid heater with air-detection. By optimizing the installation method of the detection plate, the utility model solves the problem that the detection plate may be damaged by water when cleaning a glass cup body, and at the same time solves the technical problem that a multifunctional food processing machine needs to be equipped with multiple detection plates to match the anti-overflow function of different cup bodies, which causes complex structure and increased cost.

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

[0008] The utility model provides a liquid heater with air-space detection, comprising a machine base and a glass cup body detachably mounted on the machine base, and also comprising a detection plate assembly in the shape of a strip and vertically arranged on the outside of the glass cup body, the machine base comprising a mounting platform supporting the glass cup body and an extension portion extending upward relative to the mounting platform, the detection plate assembly being protrudingly mounted on the extension portion and facing one side of the glass cup body, and the detection plate assembly abutting against the outer wall of the glass cup body after the glass cup body is installed in place.

[0009] The liquid heater provided by the utility model realizes the remote detection of the liquid level inside the glass body by adopting a strip-shaped detection plate assembly arranged vertically on the outside of the glass body, and the vertical detection height is large, the detection range is wide, and low water level dry burning detection, high water level liquid level detection and overflow prevention detection are realized, and the intelligent level is high. By setting the machine base to include a mounting platform supporting the glass body and an extension portion extending upward relative to the mounting platform, the mounting platform is used to make the glass body reliably supported above it, and the structure is stable. By setting an extension part, the extension part extends upward relative to the mounting platform to be located at the side of the glass cup body, and the detection board assembly is convexly mounted on the extension part and faces one side of the glass cup body. After the glass cup body is installed in place, the detection board assembly abuts against the outer wall of the glass cup body to achieve detection. Therefore, in the utility model, the detection board assembly is installed on the extension part, and the detection board assembly and the glass cup body are separated and independently arranged. When the user disassembles the glass cup body for cleaning, the detection board assembly is not removed with the glass cup body, thereby avoiding the risk of damage to the detection board when encountering water during the cleaning process of the glass cup body. The detection board assembly does not need to be frequently disassembled and moved with the cup body, thereby extending the service life of the detection board and improving the detection accuracy of the detection board. In addition, the weight of the glass cup body is light, which is convenient for users to take and improve the user experience. In addition, since the detection board assembly is convexly mounted on the extension part and faces one side of the glass cup body, the abutment relationship between the glass cup body and the glass cup body after the glass cup body is installed in place is more reliable, thereby reducing the distance between the detection board assembly and the liquid inside the glass cup body, making the detection of the detection board assembly more sensitive and reliable. For a liquid heater with multiple cups, multiple cups can share the detection plate assembly installed on the extension part to realize liquid level detection, thereby achieving multi-functions, meeting the anti-overflow detection needs under multiple functions, simplifying the overall structure, and reducing production costs.

[0010] In a preferred embodiment, the extension portion has an installation cavity for installing the detection board assembly, a cavity wall of the installation cavity is provided with an installation opening, and an elastic member is provided in the installation cavity for pushing the detection board assembly to extend out of the installation opening.

[0011] By providing an installation cavity in the extension part to install the detection board assembly, the detection board assembly is wrapped and protected, dust or water drops are prevented from falling on the detection board assembly to affect the detection, the service life of the detection board assembly is extended and the detection effectiveness is improved. By providing an elastic member in the installation cavity to push the detection board assembly out of the installation port, the movable installation of the detection board assembly is realized. When the user installs the glass cup body, after the glass cup body touches the detection board assembly, the elastic member is subjected to force and flexibly deformed so that the detection board assembly can be retracted into the installation cavity by a certain distance to avoid the glass cup body, avoiding too much friction on the installation of the glass cup body, causing installation difficulties for the user and the glass cup body not being installed in place, so that the installation of the glass cup body is smooth and labor-saving. When the glass cup body is installed in place, under the elastic force of the elastic member, the detection board assembly can be tightly abutted against the outer wall of the glass cup body, thereby reducing the detection distance between the detection board assembly and the liquid, and improving the sensitivity and accuracy of the detection.

[0012] In a preferred embodiment, the detection board assembly includes a protrusion protruding from the mounting port and a limiting portion connected to the protrusion and located in the mounting cavity, wherein the limiting portion is a step surface extending outward from the edge of the protrusion, and the step surface abuts against the cavity wall at the edge of the mounting port.

[0013] In a preferred embodiment, the detection board assembly includes a protruding portion protruding from the mounting port and a limiting portion connected to the protruding portion and located in the mounting cavity, and a limiting rib protruding toward the mounting cavity is provided at the mounting port, and the limiting portion is a limiting groove corresponding to the limiting rib.

[0014] By providing a protruding portion and a limiting portion, under the push-pushing action of the elastic member, the protruding portion is reliably in contact with the glass cup body, and the limiting portion is limited in cooperation with the installation opening to prevent the detection board assembly from falling out of the installation opening, and the structure is reliable. By setting the step portion as a step surface, the natural cavity wall at the edge of the installation opening is used to achieve limiting, thereby simplifying the structure of the detection board assembly and the structure of the installation cavity. The limiting of the detection board assembly is achieved by the cooperation of the limiting rib and the limiting groove, and the limiting is reliable, which effectively prevents the detection board assembly from falling out of the installation opening.

[0015] In a preferred embodiment, the elastic member is a spring or a silicone member.

[0016] The elastic part adopts a spring, which has a simple structure and a large elastic force, so that the detection board assembly can be more flexible during the installation of the glass cup body, so as to reasonably avoid the glass cup body, realize the quick installation of the glass cup body, and facilitate the operation. The use of silicone parts not only provides a certain amount of movement for the detection board assembly, but also can seal and flexibly protect the outer side of the detection board assembly, protect the detection board assembly, and extend its service life.

[0017] In a preferred embodiment, a transversely extending guide structure is provided in the extension portion, and the detection board assembly slides in the extension portion along the guide structure to protrude from the extension portion.

[0018] By setting the guide structure, on the one hand, the guide structure plays an installation guiding role during the installation of the detection plate assembly, which facilitates the positioning of the detection plate assembly and improves the installation efficiency and installation accuracy; on the other hand, the detection plate assembly slides along the guide structure to flexibly avoid the glass cup body when installing it, thereby realizing the rapid installation of the glass cup body and, at the same time, avoiding the inaccurate detection position caused by the deflection of the detection plate assembly during the activity, thereby improving the detection accuracy. Moreover, the detection plate assembly slides along the guide structure to prevent the movement from getting stuck, and the movement is smooth, so that the installation of the glass cup body is smooth.

[0019] In a preferred embodiment, the guide structure includes a hollow connecting column and a guide column, the connecting column and the guide column are respectively fixed to the detection plate assembly and the extension portion, and the connecting column can be slidably sleeved outside the guide column.

[0020] Guidance is achieved by adopting hollow connecting columns and guide columns, the structure is simple and the guiding effect is reliable.

[0021] In a preferred embodiment, the detection board assembly includes a detection board, a silicone pad and a mounting bracket, the silicone pad and the mounting bracket enclose a sealed cavity for sealing the detection board, and the detection board abuts against the outer wall of the glass cup body through the silicone pad.

[0022] The silicone pad and the mounting bracket form a sealed cavity to seal the detection board, so that the waterproof and dustproof effects of the detection board assembly are improved, the detection board is prevented from failing due to water ingress and inaccurate detection, the detection accuracy and reliability are improved, and the service life is extended. The detection board is abutted against the outer wall of the glass cup body through the silicone pad, and the abutment is tight, so that a gap is avoided between the detection board and the glass cup body, and the detection accuracy is improved.

[0023] In a preferred embodiment, the outer side wall of the glass body is provided with a detection plane, and the detection plate assembly abuts against the detection plane.

[0024] By setting up the detection plane, the distance between the detection board assembly and the liquid in the glass cup body is made more uniform, the consistency of the capacitor electrode on the detection board assembly and the liquid signal sensing is improved, the detection is more sensitive and accurate, and misjudgment and insensitive triggering are avoided. At the same time, the detection plane can make the abutment relationship between the detection board assembly and the glass cup body more reliable after the glass cup body is installed in place, so as to achieve reliable detection.

[0025] In a preferred embodiment, the machine base is provided with a mounting cavity, the bottom wall of the mounting cavity forms the mounting platform, the extension portion extends upward from the side wall of the mounting cavity, the glass cup body is installed on the mounting platform from top to bottom, and a coupler is arranged between the mounting platform and the bottom of the glass cup body.

[0026] By setting an installation cavity on the machine base, the circumferential limiting effect of the glass cup body is improved, so that the installation of the glass cup body and the machine base is stable, and the vibration and noise during the crushing operation are reduced. A coupler is set between the mounting platform and the bottom of the glass cup body to achieve electrical coupling or water coupling, so that structures such as a power supply board can be installed in the machine base, simplifying the structure of the glass cup body and saving effort for users to hold it.

[0027] In a preferred embodiment, the extension portion protrudes from the upper surface of the mounting platform and has an opening along the circumference of the glass body, the glass body is laterally mounted on the mounting platform from the opening, and a coupler is arranged between the extension portion and the side of the glass body.

[0028] By directly extending the part protruding from the upper surface of the installation platform and forming an opening, the glass body can be installed horizontally, effectively preventing the glass body and the detection board assembly from interfering during the installation of the glass body, and facilitating the user to easily install the glass body. Similarly, a coupler is provided between the extension part and the side of the glass body to achieve electrical coupling or water coupling, so that structures such as a power supply board can be installed in the base, simplifying the structure of the glass body and saving effort for the user to take it.

[0029] In a preferred embodiment, the glass cup body includes a first cup body and a second cup body, and the first cup body and the second cup body are selectively installed on the machine base.

[0030] By setting up the first cup body and the second cup body, different functions can be realized respectively and the problem of odor contamination can be prevented.

In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0045] like Figure 1 As shown, the utility model provides a liquid heater with remote detection in implementation example 1, including a base 10 and a glass cup body 20 detachably mounted on the base 10, and also including a detection board assembly 30 in a strip shape and vertically arranged on the outside of the glass cup body 20. The base 10 includes a mounting platform 11 supporting the glass cup body 20 and an extension portion 12 extending upward relative to the mounting platform 11. The detection board assembly 30 is protrudingly mounted on the extension portion 12 and faces one side of the glass cup body 20. After the glass cup body 20 is installed in place, the detection board assembly 30 abuts against the outer wall of the glass cup body 20.

[0046] Preferably, in this embodiment, the liquid heater is a soymilk machine, such as Figure 1 As shown, the liquid heater also includes a head 60 installed above the glass cup body 20, in which a motor (not shown) is provided, and the front end of the head extends into the glass cup body 20 and is provided with a crushing knife driven by the motor to prepare soy milk.

[0047] It is understandable that, in addition to the above-mentioned structure, the liquid heater may also be a soymilk maker with other structures. For example, the motor is installed in the base 10, the crushing knife is fixed at the bottom of the glass cup body 20, and the motor is connected to the crushing knife by transmission; or, in other embodiments, the liquid heater may also be a health pot, a boiling water kettle, a tea bar machine, etc.

[0048] The liquid heater provided by the utility model realizes the remote detection of the liquid level inside the glass cup body 20 by adopting a strip-shaped detection plate assembly 30 vertically arranged outside the glass cup body 20. The vertical detection has a large height and a wide detection range, and realizes low water level dry burning detection, high water level detection and anti-overflow detection, with a high level of intelligence. By setting the base 10 to include a mounting platform 11 supporting the glass cup body 20 and an extension 12 extending upward relative to the mounting platform 11, the mounting platform 11 is used to make the glass cup body 20 reliably supported above it, and the structure is stable. By setting an extension portion 12, the extension portion 12 extends upward relative to the mounting platform 11 to be located on the side of the glass cup body 20, and the detection plate assembly 30 is protrudingly mounted on the extension portion 12 and faces one side of the glass cup body 20. After the glass cup body 20 is installed in place, the detection plate assembly 30 abuts against the outer wall of the glass cup body 20 to achieve detection. Therefore, in the utility model, the detection plate assembly 30 is installed on the extension portion 12, and the detection plate assembly 30 and the glass cup body 20 are separately and independently arranged. When the user disassembles the glass cup body 20 for cleaning, the detection plate assembly 30 is not removed with the glass cup body 20, thereby avoiding the risk of the detection plate 31 being damaged by water during the cleaning process of the glass cup body 20. The detection plate assembly 30 does not need to be frequently disassembled and moved with the cup body, thereby extending the service life of the detection plate 31 and improving the detection accuracy of the detection plate 31. In addition, the glass cup body 20 is light in weight, which is convenient for users to take, thereby improving the user experience. In addition, since the detection board assembly 30 is protrudingly mounted on the extension portion 12 and faces one side of the glass cup body 20, the abutment relationship between the detection board assembly 30 and the glass cup body 20 is more reliable after the glass cup body 20 is installed in place, thereby reducing the distance between the detection board assembly 30 and the liquid inside the glass cup body 20, making the detection of the detection board assembly 30 more sensitive and reliable.

[0049] In a preferred embodiment, the glass cup body includes a first cup body and a second cup body, and the first cup body and the second cup body are selectively installed on the machine base. Optionally, the first cup body is a hot water kettle; the second cup body is a crushing cup with a crushing knife, so as to achieve multi-functions and prevent the problem of odor contamination, meet the anti-overflow detection requirements under multiple functions, and the first cup body and the second cup body share the detection board assembly in the extension part to simplify the overall structure and reduce production costs.

[0050] In a preferred embodiment, the extension portion 12 has an installation cavity for installing the detection board assembly 30, the cavity wall of the installation cavity is provided with an installation opening 123, and an elastic member 40 is provided in the installation cavity to push the detection board assembly 30 out of the installation opening 123. Specifically, Figure 2 As shown, the extension portion 12 includes a front cover 121 and a rear cover 122 fixed together, for example, by snap fastening or screw fastening. The front cover 121 and the rear cover 122 enclose a mounting cavity, and the mounting opening 123 is opened in the front cover 121. Preferably, as Figure 2 As shown, the elastic member 40 is a spring.

[0051] By providing an installation cavity in the extension portion 12 to install the detection board assembly 30, the detection board assembly 30 is wrapped and protected, dust or water drops are prevented from falling on the detection board assembly 30 to affect the detection, the service life of the detection board assembly 30 is extended, and the detection effectiveness is improved. By providing an elastic member 40 in the installation cavity to push the detection board assembly 30 out of the installation port 123, the movable installation of the detection board assembly 30 is realized. When the user installs the glass cup body 20, after the glass cup body 20 touches the detection board assembly 30, the elastic member 40 is subjected to force and flexibly deformed so that the detection board assembly 30 can be retracted into the installation cavity by a certain distance to avoid the glass cup body 20, so as to avoid too much friction on the installation of the glass cup body 20, which may cause installation difficulties for the user and the glass cup body 20 may not be installed properly, so that the installation of the glass cup body 20 is smooth and labor-saving. When the glass cup body 20 is installed in place, under the elastic force of the elastic member 40, the detection plate assembly 30 can be tightly abutted against the outer wall of the glass cup body 20, thereby shortening the detection distance between the detection plate assembly 30 and the liquid and improving the sensitivity and accuracy of the detection.

[0052] The elastic member 40 is a spring with a simple structure and a large elastic force, so that the detection board assembly 30 can be more flexible during the installation of the glass cup body 20, so as to reasonably avoid the glass cup body 20, realize the quick installation of the glass cup body 20, and facilitate the operation. Of course, in fact, the elastic member 40 can also be a silicone member, which not only provides a certain amount of movement for the detection board assembly 30, but also can seal and flexibly protect the outer side of the detection board assembly 30, protect the detection board assembly 30, and extend the service life.

[0053] It should also be noted that, in fact, the detection plate assembly 30 can also be fixed in the extension portion 12. To avoid interference with the installation of the glass cup body 20, an elastic component corresponding to the position of the detection plate assembly 30 can be set on the outside of the glass cup body 20, and the shrinkage deformation of the elastic component can be used to reduce the friction during the installation of the glass cup body 20.

[0054] Preferably, in order to prevent the detection board assembly 30 from being separated from the installation opening 123, a limit is provided between the detection board assembly 30 and the installation opening 123, for example:

[0055] Implementation example 1, such as Figure 3 , Figure 4 As shown, the detection board assembly 30 includes a protruding portion 301 protruding from the mounting port 123 and a limiting portion 302 connected to the protruding portion 301 and located in the mounting cavity. A limiting rib 305 protruding toward the mounting cavity is provided at the mounting port 123, and the limiting portion 302 is a limiting groove corresponding to the limiting rib 305.

[0056] Preferably, the limiting rib 305 is annular around the installation opening 123 to achieve multi-directional limiting.

[0057] In this implementation example, combined with Figure 2 As shown, the detection board assembly 30 includes a detection board 31, a silicone pad 32 and a mounting bracket 33. The silicone pad 32 and the mounting bracket 33 enclose a sealed cavity to seal the detection board 31. The detection board 31 abuts against the outer wall of the glass cup body 20 through the silicone pad 32. Specifically, the protrusion 301 and the limiter 302 are both located on the silicone pad 32, and the limiter groove is provided on the side of the silicone pad 32 facing the glass cup body 20. More specifically, the detection board 31 includes a substrate arranged vertically outside the glass cup body, an electrode sheet provided on one side of the substrate (the side facing the glass cup body), a control chip provided on the other side of the substrate, and connecting leads.

[0058] The silicone pad 32 and the mounting bracket 33 enclose a sealed cavity for sealing the detection board 31, so that the waterproof and dustproof effects of the detection board assembly 30 are improved, and the detection board 31 is prevented from failing due to water ingress and inaccurate detection, thereby improving the detection accuracy and reliability and extending the service life. The detection board 31 is closely abutted against the outer wall of the glass cup body 20 through the silicone pad 32, avoiding the occurrence of a gap between the detection board 31 and the glass cup body 20, and improving the accuracy of the detection.

[0059] Implementation Example 2, such as Figure 6 and Figure 7 As shown, the detection board assembly 30 includes a protrusion 301 protruding from the installation port 123 and a limiting portion 302 connected to the protrusion 301 and located in the installation cavity. The limiting portion 302 is a step surface extending outward from the edge of the protrusion 301, and the step surface abuts against the cavity wall at the edge of the installation port 123.

[0060] By setting the protrusion 301 and the limiting portion 302 on the detection plate assembly 30, under the push and push action of the elastic member 40, the protrusion 301 is reliably in contact with the glass cup body 20, and the limiting portion 302 is limited and matched with the installation opening 123 to prevent the detection plate assembly 30 from escaping or falling from the installation opening 123, and the structure is reliable. By setting the step portion as a step surface, the natural cavity wall at the edge of the installation opening 123 is used to achieve the limit, which simplifies the structure of the detection plate assembly 30 and the structure of the installation cavity. The detection plate assembly 30 is limited by the cooperation of the limiting rib and the limiting groove, and the limit is reliable, which effectively prevents the detection plate assembly 30 from escaping from the installation opening 123.

[0061] It can be understood that in this embodiment, the detection board assembly 30 can be selected as the structure in embodiment 1. More specifically, the protrusion 301 and the limiting portion 302 are both located on the silicone pad 32, and the step surface is arranged on the side of the silicone pad 32 facing the glass cup body 20.

[0062] In implementation example 2, if Figure 6 , Figure 7 As shown, the liquid heater is a water boiler. Optionally, a cup cover is hingedly connected to the open end of the glass cup body.

[0063] In a preferred embodiment of the present invention, a transversely extending guide structure is provided in the extension portion 12, and the detection plate assembly 30 slides along the guide structure in the extension portion 12 to protrude from the extension portion 12. Figure 2 , Figure 3 , Figure 4 As shown, the guide structure includes a hollow connecting column 304 and a guide column 303, and the connecting column 304 and the guide column 303 are respectively fixed to the detection plate assembly 30 and the extension portion 12, that is, the connecting column 304 is convexly arranged on the mounting bracket 33, and the guide column 303 is convexly arranged on the rear cover 122, referring to Figure 5 , Figure 2 The connecting column 304 can be slidably sleeved outside the guide column 303. More preferably, the spring is sleeved outside the connecting column 304 as the elastic member 40.

[0064] By setting the guide structure, on the one hand, the guide structure plays an installation guide role in the process of installing the detection plate assembly 30, which facilitates the positioning of the detection plate assembly 30 and improves the installation efficiency and installation accuracy; on the other hand, the detection plate assembly 30 slides along the guide structure to flexibly avoid the glass cup body 20 when installing, so as to achieve the rapid installation of the glass cup body 20, and at the same time, avoid the inaccurate detection position caused by the deflection of the detection plate assembly 30 during the activity, so as to improve the accuracy of the detection, and the detection plate assembly 30 slides along the guide structure to prevent the movement from being stuck, and the movement is smooth, so that the installation of the glass cup body 20 is smooth. The hollow connecting column 304 and the guide column 303 are used to achieve guidance, which has a simple structure and a reliable guiding effect.

[0065] Of course, in addition to the matching mode of the connecting column 304 and the guide column 303, the guide structure can actually be a guide groove. The guide groove is formed by setting a rib or a depression on the side wall of the installation cavity, and the detection board assembly 30 is slidably installed in the guide groove to achieve guidance.

[0066] In a preferred embodiment, the outer wall of the glass body 20 is provided with a detection plane, and the detection plate assembly 30 abuts against the detection plane. Optionally, the detection plane is integrally formed during the die-casting process of the glass body or formed by setting a cutting plane on the outer side of the glass body.

[0067] By setting the detection plane, the distance between the detection board assembly 30 and the liquid in the glass cup body 20 is made more uniform, the consistency between the capacitor electrode on the detection board assembly 30 and the liquid signal sensing is improved, the detection is more sensitive and accurate, and misjudgment and insensitive triggering are avoided. At the same time, the detection plane can make the abutment relationship between the detection board assembly 30 and the glass cup body 20 more reliable after the glass cup body 20 is installed in place, so as to achieve reliable detection.

[0068] It should also be noted that the present invention does not limit the specific structure of the base 10. For example, in Example 1, Figure 1 As shown, the base 10 is provided with a mounting cavity, the bottom wall of the mounting cavity forms a mounting platform 11, the extension portion 12 extends upward from the side wall of the mounting cavity, the glass cup body 20 is mounted on the mounting platform 11 from top to bottom, and a coupler is arranged between the mounting platform 11 and the bottom of the glass cup body 20, as shown in FIG. Figure 1 As shown, the coupler includes an upper coupler 51 fixed to the bottom of the glass body 20 and a lower coupler 52 fixed to the mounting platform 11 .

[0069] By setting an installation cavity on the machine base 10, the circumferential limiting effect of the glass cup body 20 is improved, so that the installation of the glass cup body 20 and the machine base 10 is stable, and the vibration noise during the crushing operation is reduced. A coupler is set between the installation platform 11 and the bottom of the glass cup body 20 to achieve electrical coupling or water coupling, so that structures such as a power supply board can be installed in the machine base 10, simplifying the structure of the glass cup body 20 and saving effort for users to hold it.

[0070] In other embodiments, the extension portion 12 protrudes from the upper surface of the mounting platform 11 and has an opening along the circumference of the glass cup body 20. The glass cup body 20 is laterally installed on the mounting platform 11 from the opening, and a coupler is arranged between the extension portion 12 and the side of the glass cup body 20.

[0071] By directly extending the portion 12 protruding from the upper surface of the mounting platform 11 and forming an opening, the glass body 20 can be installed horizontally, effectively preventing the glass body 20 and the detection board assembly 30 from interfering during the installation of the glass body 20, and facilitating the user to easily install the glass body 20. Similarly, by providing a coupler between the extension portion 12 and the side of the glass body 20, electrical coupling or water coupling can be achieved, so that structures such as a power supply board can be installed in the base 10, simplifying the structure of the glass body 20 and making it easier for the user to take it.

[0072] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0073] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0074] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
