Description

Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and in particular relates to a cooking appliance with a weighing function. Background Art

[0002] In actual use, induction cookers are often used to heat food for a long time, such as for cooking hot pot. During the cooking process, the weight of the food will change frequently due to evaporation of water, users taking food, adding new food or soup, so during this process, users need to constantly adjust the power of the induction cooker to adapt to the change in the amount of food, which greatly reduces the user experience.

[0003] In order to solve this technical problem, some induction cookers have appeared in the prior art that can adjust the power according to the weight of the ingredients. By setting a weighing sensor on the bottom plate of the induction cooker, the evaporation condition and / or the weight condition of the pot body are identified according to the output signal of the weighing sensor, and then the boiling condition of the hot pot and / or the remaining condition of the ingredients are known, so as to automatically adjust the heating power.

[0004] In a specific induction cooker product, it includes a panel and a bottom plate located below the panel. The panel and the bottom plate cooperate to form a cavity. A control unit, an electromagnetic heating unit and a weighing unit are arranged in the cavity. A support body is provided between the panel and the bottom plate. The support body supports the entire panel on the bottom plate. The upper surface of the panel is used to place heating dishes or pots. The weighing unit is arranged on the bottom plate and is located directly below the electromagnetic heating unit. When the weight of the heating dishes or pots placed on the panel changes, the panel will produce a slight displacement in the up and down directions. The slight displacement is transmitted from the support body to the bottom plate, thereby causing a corresponding change in the pressure of the weighing unit arranged on the bottom plate. The weighing unit transmits the generated pressure signal to the control unit to perform corresponding power adjustment.

[0005] The weighing module needs to connect the sensor and controller through connecting wires. However, after the weighing module is assembled, the sensor wire outlet is close to the base, leaving little space for the connecting wires. The connecting wires are prone to hit the side walls of the base when arranged. During the assembly process, they are prone to bend and shift due to the friction and pulling of the base, affecting the normal use of the connecting wires or even causing them to break.

[0009] The cooking appliance with weighing function described in the present application also includes the following additional technical features:

[0010] The protection plate is arranged corresponding to the lead wire opening in the vertical direction, and the upward projection of the protection plate covers the portion of the lead wire located in the lead wire channel.

[0011] The lead wire channel comprises a first escape space for escaping the lead wire, the rib comprises a first outward expansion section which expands toward the outside of the accommodating cavity to form the first escape space, and the protective plate extends laterally toward the first outward expansion section.

[0012] The lead wire channel comprises a second escape space for escaping the lead wire, and the rib comprises a second outward expansion section which expands toward the outside of the accommodating cavity to form the second escape space.

[0013] The first outward expansion section and the second outward expansion section are arranged up and down, and the first outward expansion section and the second outward expansion section are both arc-shaped, and the curvature radius of the first outward expansion section is greater than the curvature radius of the second outward expansion section, so as to form a baffle at the connection position between the two that can cover a partial area of ​​the lead.

[0014] A lead groove for allowing the lead to pass through the accommodating cavity is provided on the upper portion of the rib, a circuit board is provided inside the base, and the lead passes through the lead groove to be electrically connected to the circuit board.

[0015] A plurality of weighing units are arranged around the base, and a wire groove is arranged on the upper part of each rib for the lead wire to pass through the accommodating cavity; the opening of each wire groove faces the center of the base; or, an even number of weighing units are arranged opposite to each other in the base, and the openings of two wire grooves in relative positions face each other.

[0016] An upper boss and a lower boss are convexly arranged in the accommodating cavity, the weighing unit comprises a support beam and a strain beam connected to the support beam, the lead wire is fixed to the strain beam, and the support beam is clamped between the upper boss and the lower boss.

[0017] The ribs include two opposite first side walls and two opposite second side walls, the lower boss is arranged on the second side walls, one of the first side walls is provided with a first outward expansion section that expands toward the outside of the accommodating cavity to form a first avoidance space, and the distance between the outer periphery of the support beam and the first side wall provided with the first outward expansion section is greater than the distance between the outer periphery of the support beam and the other first side wall.

[0018] A clamping rib connected to the bottom of the rib and extending upward is further provided in the accommodating cavity, a deformation space exists between the clamping rib and the rib, and the lower boss is provided on a side of the clamping rib facing the accommodating cavity.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0020] 1. The base of the cooking utensil in the present application is provided with ribs for enclosing a receiving cavity. The ribs provide a mounting position for the weighing unit on the one hand, and cooperate with the weighing sensor on the other hand to form a lead channel for the lead wire to pass through. The setting of the lead channel can reduce the probability of the lead wire being interfered by the base or other components, and reduce the influence of adjacent components on the lead wire when the cooking utensil is vibrated or impacted, thereby providing guarantee for the normal operation of the lead wire. In addition, the weighing sensor is provided with a lead opening at the position corresponding to the lead channel. On the one hand, the lead opening can provide guidance for the arrangement of the leads during assembly, so that during the lead assembly process, the assembler can more easily control the arrangement of the leads in a preset direction. Compared with arranging the lead opening on the weighing bracket or other positions, arranging the lead opening on the weighing sensor can shorten the distance that the leads in the accommodating cavity extend from the weighing sensor to the greatest extent, reduce the lead's demand for the lateral space of the accommodating cavity, help to miniaturize the reinforcement surrounding the accommodating cavity, improve the structural strength of the base, and optimize the structural layout of the cooking appliance; on the other hand, the lead opening can also play a local limiting role on the leads, so that the leads are arranged in a fixed position, reducing the probability of damage such as pulling caused by external forces during the connection with the electronic control board. Moreover, the lead wire also has a bent portion formed by bending at the lead wire mouth. The setting of the bent portion increases the length margin of the lead wire. When the lead wire is pulled by an external force, the bent portion can be gradually straightened by the bending under the pulling action, so that the lead wire has a certain deformation margin when it is pulled or subjected to other actions, thereby reducing the possibility of the lead wire being torn by external forces, and further providing a guarantee for the normal operation of the lead wire. Furthermore, the cooking utensil of the present application is also provided with a protective plate, and the upward projection of the protective plate at least covers the bent portion to isolate the bent portion from the base in the vertical direction, thereby reducing the influence of the base on the lead wire during assembly or use in multiple directions. In addition, the upward projection of the protective plate at least covers the bent portion, and can also prevent the lead wire from being exposed, thereby achieving protection for the lead wire.

[0021] 2. As a preferred embodiment of the present invention, the protective plate and the lead-in port are arranged correspondingly in the vertical direction, and the upward projection of the protective plate covers the portion of the lead located in the lead-in channel. By setting the protective plate so that its upward projection covers the portion of the lead located in the lead-in channel, on the one hand, the protective plate can completely isolate the lead located in the lead-in channel from the base, thereby minimizing the interference of the base on the lead; on the other hand, the protective plate can be preferably arranged so that the outer periphery is in contact with the inner wall of the accommodating cavity, and during the assembly process, the protective plate can be placed on the side wall of the ribs in the accommodating cavity to achieve circumferential limitation of the protective plate, thereby eliminating the need to set a limiting member in the accommodating cavity to limit the displacement of the protective plate to ensure that the upward projection of the limiting member can cover the portion of the lead located in the lead-in channel, thereby reducing the difficulty of assembling the protective plate.

[0022] 3. As a preferred embodiment of the utility model, by setting the first avoidance space, on the one hand, the operating space for arranging the lead during assembly is increased, so that the lead is less likely to interfere with other components when arranged in a larger operating space; on the other hand, during use, the setting of the first avoidance space increases the distance between the lead and other components. When the cooking appliance is subjected to external force to cause relative displacement of the internal components, the lead located in the first avoidance space has more relative displacement distance with other components, reducing the probability of the lead interfering with other components and being affected by pulling friction, etc., and providing protection for the normal operation of the lead. In addition, the protective plate extends laterally toward the first expansion section, increasing its upward projection area, that is, increasing the isolation area between the lead and the base, and improving the protective effect of the lead.

[0023] 4. As a preferred embodiment of the present invention, the lead channel includes a second avoidance space for avoiding the lead, and the rib has a second outward expansion section that expands toward the outside of the accommodating cavity to form the second avoidance space. By providing the second avoidance space, the lead has a larger arrangement space on the basis of the first avoidance space, further reducing the difficulty of lead arrangement during assembly while further increasing the distance between the lead and other components, thereby further reducing the probability of interference between the lead and other components and being affected by pulling friction.

[0024] 5. As a preferred embodiment of the present invention, the first expansion section and the second expansion section are arranged up and down, and both of them are arc-shaped, and the curvature radius of the first expansion section is greater than the curvature radius of the second expansion section, so as to form a stopper at the connection position between the two sections that can block part of the lead wire. The first expansion section and the second expansion section are arranged up and down, so that there is a certain degree of overlap between the first expansion section and the second expansion section in the vertical direction, which saves the space occupied by the ribs in the horizontal direction of the base, saves more installation space for other components, and optimizes the spatial layout of the cooking utensil; in addition, the stopper formed by the first expansion section and the second expansion section can block part of the lead wire, reduce the exposed area of ​​the lead wire in the horizontal plane, and play a certain protective role on the lead wire.

[0025] 6. As a preferred embodiment of the present invention, by setting up multiple weighing units, the weight of the food can be weighed more accurately. When the food is placed on the cooking utensil, the upper shell will be squeezed and deformed to squeeze the base, thereby obtaining the weight of the food. However, due to the randomness of the placement of the food, the degree of squeezing on the upper shell may be different, resulting in different degrees of deformation at each part of the upper shell. Therefore, a single weighing unit may have a certain deviation in weighing the food placed at different positions. By setting up multiple weighing units, the weighing error of the food placed at different positions can be reduced to a certain extent, and the accuracy of weighing can be improved. In addition, setting up multiple weighing units can effectively prevent the cooking utensil from being unable to realize the weighing function after a single weighing unit is damaged, thereby improving the user experience. Since the lead groove is set at the upper part of the reinforcement, compared with opening grooves at the bottom of the reinforcement or other positions, opening the lead groove at the upper part of the reinforcement can enhance the connection stability between the reinforcement and the base and improve the structural strength of the reinforcement; in addition, when laying the lead wire, passing the lead wire through the lead groove located above the reinforcement can reduce the shielding of the lead wire by the reinforcement, so that most of the lead wire is exposed to the field of vision of the assembler, reducing the assembly difficulty of the assembler. Since the lead wire serves as the connection line between the weighing sensor and the main control board, the opening of the lead groove is set to face the center of the base, and the main control board can be preferably set at the center of the base, shortening the distance between each weighing unit and the main control board, thereby shortening the lead wire length required for each weighing unit, improving the data transmission efficiency, and facilitating the real-time feedback of the weighing results. By arranging the weighing units in an even number facing each other and making the lead slot openings of the two weighing units face each other, the leads of the two weighing units can be arranged symmetrically, that is, the directions of the leads in the two weighing units are arranged consistently, and there is no need to plan multiple lead layout lines. This optimizes the structural design of the weighing units while reducing the difficulty of assembly, which helps to improve assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] like Figures 1 to 3 As shown, a cooking utensil with a weighing function comprises a base 1 and an upper shell arranged on the base 1 to support a pot body, a weighing unit 3 is arranged at the bottom of the base 1, a rib 2 for enclosing a receiving cavity 5 is convexly arranged on the base 1, the receiving cavity 5 is used to receive the weighing unit 3, the weighing unit 3 comprises a weighing bracket 31, a weighing sensor 32 and a lead 33 electrically connected to the weighing sensor 32, a lead channel for the lead 33 to pass through the receiving cavity 5 is formed between the weighing sensor 32 and the rib 2, the weighing sensor 32 is provided with a lead opening 321 for the lead 33 to pass through corresponding to the lead channel, the lead 33 is bent at the lead opening 321 to form a bent portion 331, the weighing bracket 31 is provided with a protective plate 311 located below the lead 33, and the upward projection of the protective plate 311 at least covers the bent portion 331.

[0048] In the present application, the base 1 of the cooking utensil is provided with a rib 2 for enclosing a receiving cavity 5. The rib 2 provides a mounting position for the weighing unit 3 on the one hand, and cooperates with the weighing sensor 32 on the other hand to form a lead channel for the lead 33 to pass through. The setting of the lead channel can reduce the probability of the lead 33 being interfered by the base 1 or other components, and reduce the influence of adjacent components on the lead 33 when the cooking utensil is vibrated or impacted, thereby providing a guarantee for the normal operation of the lead 33. In addition, the weighing sensor 32 is provided with a lead opening 321 at the position corresponding to the lead channel. On the one hand, the lead opening 321 can provide guidance for the arrangement of the lead 33 during assembly, so that during the assembly process of the lead 33, the assembler can easily control the lead 33 to be arranged in a preset direction. Compared with arranging the lead opening 321 on the weighing bracket 31 or other positions, arranging the lead opening 321 on the weighing sensor 32 can shorten the distance of the lead 33 extending from the weighing sensor 32 in the accommodating cavity 5 to the greatest extent, reduce the demand of the lead 33 for the lateral space of the accommodating cavity 5, help to miniaturize the ribs 2 surrounding the accommodating cavity 5, improve the structural strength of the base 1, and optimize the structural layout of the cooking utensil; on the other hand, the lead opening 321 can also play a local limiting role on the lead 33, so that the lead 33 is arranged in a fixed orientation, reducing the probability of the lead 33 being damaged by external force and being pulled during the connection with the circuit board. Moreover, the lead wire 33 also has a bent portion 331 formed by bending at the lead wire opening 321. The setting of the bent portion 331 increases the length margin of the lead wire 33. When the lead wire 33 is pulled by an external force, the bent portion 331 can be gradually straightened by the pulling action, so that the lead wire 33 has a certain deformation margin when it is pulled or subjected to other actions, thereby reducing the possibility of the lead wire 33 being torn by an external force, and further providing a guarantee for the normal operation of the lead wire 33. Furthermore, the cooking utensil of the present application is also provided with a protective plate 311, and the upward projection of the protective plate 311 at least covers the bent portion 331, so as to isolate the bent portion 331 from the base 1 in the vertical direction, and reduce the influence of the base 1 on the lead wire 33 in multiple directions during assembly or use. In addition, the upward projection of the protective plate 311 at least covers the bent portion 331, and can also prevent the lead wire 33 from being exposed, thereby realizing the protection of the lead wire 33.

[0049] The present application does not limit the structure and forming method of the lead-in opening 321, which can be as follows: Figure 4 As shown, a slot is opened at the end of the weighing sensor 32 as a lead-in opening 321. The lead-in opening 321 in this embodiment can limit the displacement of the lead 33 along a direction perpendicular to the length of the lead 33, and has little effect on the strength of the weighing sensor 32. It can also be a limit hole opened on the weighing sensor 32, and the limit hole is used as the lead-in opening 321. The lead-in opening 321 in this embodiment can limit the displacement of the lead 33 along the horizontal direction.

[0050] As a preferred embodiment of the present application, Figure 3 As shown, the protective plate 311 and the lead-in opening 321 are arranged correspondingly in the vertical direction, and the upward projection of the protective plate 311 covers the portion of the lead 33 located in the lead-in channel. The protective plate 311 is arranged so that its upward projection covers the portion of the lead 33 located in the lead-in channel. On the one hand, the protective plate 311 can completely isolate the lead 33 located in the lead-in channel from the base 1, thereby avoiding interference of the base 1 on the lead 33 to the greatest extent. Preferably, the protective plate 311 is arranged so that the outer periphery is in contact with the inner wall of the accommodating cavity 5. During the assembly process, the protective plate 311 is placed on the side wall of the inner rib 2 of the accommodating cavity 5 to achieve circumferential limitation of the protective plate 311, eliminating the need to set a limiting member in the accommodating cavity 5 to limit the displacement of the protective plate 311 to ensure that the upward projection of the limiting member can cover the portion of the lead 33 located in the lead-in channel, thereby reducing the difficulty of assembling the protective plate 311.

[0051] As a preferred embodiment of the present application, Figure 5 As shown, the lead channel includes a first avoidance space for avoiding the lead 33, the rib 2 has a first outward expansion section 21 that expands toward the outside of the accommodating cavity 5 to form the first avoidance space, and the protective plate 311 extends laterally toward the first outward expansion section 21.

[0052] By setting the first avoidance space, on the one hand, the operating space for arranging the lead 33 during assembly is increased, so that the lead 33 has a lower possibility of interfering with other components when arranged in a larger operating space; on the other hand, during use, the setting of the first avoidance space increases the distance between the lead 33 and other components. When the cooking appliance is subjected to external force to cause relative displacement of the internal components, the lead 33 located in the first avoidance space has more relative displacement distance with other components, reducing the probability of the lead 33 interfering with other components and being affected by pulling friction, etc., and providing protection for the normal operation of the lead 33. In addition, the protective plate 311 extends laterally toward the first expansion section 21, increasing its upward projection area, that is, increasing the isolation area between the lead 33 and the base 1, and improving the protective effect of the lead 33.

[0053] As a preferred embodiment of this implementation, Figure 5As shown, the lead channel includes a second avoidance space for avoiding the lead 33, and the rib 2 has a second outward expansion section 22 that expands toward the outside of the accommodating cavity 5 to form the second avoidance space. By providing the second avoidance space, the lead 33 has a larger arrangement space on the basis of the first avoidance space, further reducing the difficulty of arranging the lead 33 during assembly while further increasing the spacing between the lead 33 and other components, thereby further reducing the probability of interference between the lead 33 and other components and being affected by pulling friction.

[0054] As a preferred example under this embodiment, Figure 5 As shown, the first expansion section 21 and the second expansion section 22 are arranged up and down, and both the first expansion section 21 and the second expansion section 22 are arc-shaped, and the curvature radius of the first expansion section 21 is greater than the curvature radius of the second expansion section 22, so as to form a stopper 26 at the connection position of the two sections that can block a part of the lead 33. The first expansion section 21 and the second expansion section 22 are arranged up and down, so that there is a certain degree of overlap between the first expansion section 21 and the second expansion section 22 in the vertical direction, which saves the space occupied by the rib 2 in the horizontal direction of the base 1, saves more installation space for other components, and optimizes the spatial layout of the cooking utensil; in addition, the stopper 26 composed of the first expansion section 21 and the second expansion section 22 can block part of the lead 33, reduce the exposed area of ​​the lead 33 in the horizontal plane, and play a certain protective role on the lead 33.

[0055] The present embodiment does not limit the arrangement positions of the first outward expansion section 21 and the second outward expansion section 22. The first outward expansion section 21 and the second outward expansion section 22 may be arranged alternately in the vertical direction, and there may be a certain degree of staggering and deviation in their projections on the horizontal plane. The present embodiment also does not limit the structural form of the first outward expansion section 21 and the second outward expansion section 22. The first outward expansion section 21 and the second outward expansion section 22 may be arranged to have a straight-edge structure with an angle in their projections on the horizontal plane.

[0056] As a preferred embodiment of the present application, Figure 5As shown, the upper part of the rib 2 is provided with a lead wire 33 slot 23 for the lead wire 33 to pass through the accommodating cavity 5, and a circuit board is provided inside the base 1, and the lead wire 33 passes through the lead wire 33 slot 23 to be electrically connected to the circuit board. The lead wire 33 slot 23 is arranged on the upper part of the rib 2, so that the lead wire 33 can be exposed to the field of vision of the assembler when the lead wire 33 is assembled. Compared with the lead wire 33 slot 23 being arranged in the middle or bottom of the rib 2, the shielding of the lead wire 33 by the rib 2 can be reduced, thereby reducing the difficulty of assembly; in addition, the lead wire 33 slot 23 is arranged on the upper part of the rib 2 to reduce the distance between the lead wire 33 and the connection between the weighing sensor 32 and the circuit board, saving the length of the lead wire 33 and optimizing the layout of the lead wire 33.

[0057] As a preferred embodiment of the present application, Figure 1 As shown, a plurality of weighing units 3 are provided around the base 1, and a lead wire 33 groove 23 is provided on the upper portion of each of the ribs 2 for the lead wire 33 to pass through the accommodating cavity 5; the opening of each of the lead wire 33 grooves 23 faces the center of the base 1; or, an even number of weighing units 3 are provided in pairs opposite to each other in the base 1, and the openings of two of the lead wire 33 grooves 23 in relative positions face each other.

[0058] By setting a plurality of weighing units 3, the weight of the food can be weighed more accurately. When the food is placed on the cooking utensil, the upper shell will be squeezed and deformed to squeeze the base 1, thereby obtaining the weight of the food. However, due to the randomness of the placement of the food, the degree of squeezing on the upper shell may be different, resulting in different degrees of deformation at each part of the upper shell. Therefore, a single weighing unit 3 may have a certain deviation in weighing the food placed at different positions. By setting a plurality of weighing units 3, the weighing error of the food placed at different positions can be reduced to a certain extent, and the accuracy of weighing can be improved. In addition, setting a plurality of weighing units 3 can effectively prevent the cooking utensil from being unable to realize the weighing function after a single weighing unit 3 is damaged, thereby improving the user experience. Since the lead wire 33 slot 23 is set at the upper part of the reinforcement 2, compared with slotting at the bottom of the reinforcement 2 or other positions, the lead wire 33 slot 23 is set at the upper part of the reinforcement 2 to enhance the connection stability between the reinforcement 2 and the base 1, and improve the structural strength of the reinforcement 2; in addition, when laying the lead wire 33, passing the lead wire 33 through the lead wire 33 slot 23 located above the reinforcement 2 can reduce the shielding of the lead wire 33 by the reinforcement 2, so that most of the lead wire 33 is exposed to the field of vision of the assembler, reducing the assembly difficulty of the assembler. Since the lead wire 33 is used as the connecting line between the weighing sensor 32 and the main control board, the opening of the lead wire 33 slot 23 is set to face the center of the base 1, and the main control board can be preferably set at the center of the base 1, shortening the distance between each weighing unit 3 and the main control board, thereby shortening the length of the lead wire 33 required for each weighing unit 3, improving the data transmission efficiency, and facilitating the real-time feedback of the weighing result. By arranging the weighing units 3 in an even number facing each other, and making the openings of the lead wire 33 slots 23 of two relative weighing units 3 face each other, the leads 33 of the two relative weighing units 3 can be arranged symmetrically, that is, the directions and layouts of the leads 33 in the two relative weighing units 3 are consistent, and there is no need to plan multiple lead wire 33 arrangement lines, which optimizes the structural design of the weighing units 3 while reducing the assembly difficulty, thereby helping to improve assembly efficiency.

[0059] As a preferred embodiment of the present application, Figure 6 , Figure 7As shown, an upper boss 6 and a lower boss 7 are convexly provided in the accommodating cavity 5, the weighing unit 3 comprises a support beam 34 and a strain beam 35 connected to the support beam 34, the lead wire 33 is fixed to the strain beam 35, and the support beam 34 is clamped between the upper boss 6 and the lower boss 7. By providing the support beam 34 and the strain beam 35, the support beam 34 cooperates with the upper boss 6 and the lower boss 7 to realize the installation of the weighing unit 3, and the strain beam 35 only bears the weighing function without being disturbed by the strain caused by the clamping during installation, which helps to improve the anti-interference ability of the weighing unit 3; in addition, since the upper boss 6 and the lower boss 7 are convexly provided in the accommodating cavity 5 and are integrally formed with the rib 2, during assembly, it is unnecessary to separately install the installation structure for fixing the support beam 34 after installing the rib 2, thereby simplifying the assembly process.

[0060] As a preferred embodiment of this embodiment, as shown in FIG. 5 , the rib 2 includes two opposite first side walls 24 and two opposite second side walls 25, the lower boss 7 is arranged on the second side walls 25, one of the first side walls 24 is provided with a first expansion section 21 that expands toward the outside of the accommodating cavity 5 to form a first avoidance space, and the distance between the outer periphery of the support beam 34 and the first side wall 24 provided with the first expansion section 21 is greater than the distance between the outer periphery of the support beam 34 and the other first side wall 24. By providing the first expansion section 21, more space is reserved for the stretching arrangement of the lead 33 during assembly, so that the lead 33 can have more deformation space; during use, when the lead 33 is deformed by external force, the provision of the first expansion section 21 reduces the probability of friction between the lead 33 and the side wall of the rib 2 when deforming, thereby reducing the risk of damage to the lead 33.

[0061] As another preferred embodiment of this embodiment, Figure 7 As shown, the accommodating cavity 5 is further provided with a clamping rib 4 connected to the bottom of the rib 2 and extending upward, a deformation space is provided between the clamping rib 4 and the rib 2, and the lower boss 7 is provided on the side of the clamping rib 4 facing the accommodating cavity 5. By providing the clamping rib 4 and providing the lower boss 7 on the side of the clamping rib 4 facing the accommodating cavity 5, when the weighing unit 3 needs to be replaced, the clamping rib 4 is pushed toward the side away from the accommodating cavity 5 to achieve the displacement of the upper boss 6 and the lower boss 7, thereby releasing the support beam 34 between the upper boss 6 and the lower boss 7, and then realizing the disassembly of the weighing unit 3, and the disassembly process is relatively quick and convenient.
