Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of weighing devices, in particular to a weighing assembly and a pet toilet. BACKGROUND

[0002] In life, common weighing devices include body scales, article scales, etc., which generally have a weighing sensor inside. In some pet products, in order to meet the needs of users to better understand the living habits of pets, some pet products also have a weighing sensor, such as pet feeders, pet water dispensers, pet cages, pet nests, pet backpacks, and pet toilets, etc.

[0003] Since the weighing sensor is an element that converts the mass signal into a measurable signal (such as an electrical signal) and outputs it to the outside, that is, when an object is placed on the weighing sensor, the weighing sensor will deform or displace due to the gravity of the object. Therefore, in the support structure of the weighing sensor, a movable structure that can follow the deformation or displacement of the weighing sensor is generally provided.

[0004] A device using a weighing sensor generally includes a weighing support for accommodating a weighing object, a main support for mounting the weighing support, a weighing sensor, and a support structure thereof.

[0005] In a pet water dispenser, the weighing object is the water in the water dispenser, so the weighing support can be a water tank for storing water. The main support of the pet water dispenser can be a water dispenser base for mounting the water tank. In a pet toilet, the weighing object is pet litter or the entire litter bin that contains pet litter, so the weighing support can be a base for mounting the litter bin. The main support can be a base for mounting the base.

[0006] Taking a pet toilet as an example, the weighing sensor support structure generally includes an outer support and an inner support. During installation, the outer support can be mounted on the base described above. The inner support is used to abut against the base described above. The weighing sensor is mounted on the inner support and abuts against the outer support. When the base is mounted on the base, the gravity acting on the base will cause the weighing sensor to deform, and in turn, the inner support will move relative to the outer support. However, this will also cause the existence of a gap between the inner support and the outer support.

[0007] In actual application, gaps can be formed between the inner support and the outer support, between the inner support and the litter bin, between the weighing sensor and the outer support, etc. The above-mentioned gaps can enter dust, insects, and litter, etc. Not only is it inconvenient to clean, but it can also cause harm to the health of pets and users.

[0081] The technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0082] In the description of the embodiments of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0083] In the description of the embodiments of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be replaceably connected, or it can be integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0084] The embodiments of the present application provide a plurality of weighing assemblies and pet toilets applying the weighing assemblies. In actual application, the weighing assemblies can be applied to pet feeders, pet water dispensers, pet cages, pet nests, pet outing backpacks and pet toilets and other pet products.

[0085] Referring to Figure 1 , the first aspect of the embodiments of the present application provides a weighing assembly, comprising: a first support 10, a second support 20, a weighing sensor 30 and an elastic pad 40.

[0086] The first support 10 is a fixed part, which can be fixedly connected with the main frame of the pet product.

[0087] In the present application, the second support 20 can be arranged on the first support 10, and the second support 20 is movably arranged relative to the first support 10. Here, the movable connection between the second support 20 and the first support 10 can mean that the second support 20 is a movable part, which can be connected in a sliding manner or the like to make the second support 20 move as a whole relative to the first support 10. It can also mean that the second support 20 is a deformable elastic structure, which will deform when the second support 20 is stressed, so that the second support 20 as a whole or partially moves relative to the first support 10.

[0088] The weighing sensor 30 is arranged between the first support 10 and the second support 20, and simultaneously abuts against the first support 10 and the second support 20. As Figure 1 and Figure 2 shown, in the present embodiment, the weighing sensor 30 can be provided with a contact 31, and when the second support 20 is stressed, the second support 20 will press the contact 31 to make the weighing sensor 30 deform, so as to measure the weight. In practical applications, the weighing sensor 30 can be a resistance strain type weighing sensor, a capacitance type weighing sensor, an inductance type weighing sensor, a pressure type weighing sensor, etc. The elastic pad 40 connects the first support 10 and the second support 20, and seals the space between the first support 10 and the second support 20. The area between the elastic pad 40, the first support 10 and the second support 20 is a sealed area. The weighing sensor 30 is arranged in the sealed area, so that the elastic pad 40 can play a protective role for the weighing sensor 30.

[0089] In practical applications, the sealed area is enclosed by the elastic pad 40, the first support 10 and the second support 20, or the sealed area is enclosed by the elastic pad 40, the first support 10, the second support 20 and a cooperating component. The cooperating component can be, for example, an electric wire; specifically, the first support 10 can be provided with a wire hole, the electric wire passes through the wire hole to connect the weighing sensor 30 in the sealed area, and the electric wire seals the wire hole. In the case where the weighing sensor 30 is a wireless sensor, the above-mentioned electric wire and wire hole can not be provided.

[0090] For example, the weighing assembly is applied to a pet toilet, as Figure 1 and Figure 2As shown, the first support 10 can be connected to the base of the litter box; the base is used for placing the litter bin. The second support 20 can be connected to the bottom of the litter box or connected to the first support 10, specifically so that the second support 20 abuts against the bottom. The bottom is used for placing the base. When the base is placed on the bottom, the first support 10 will be deformed downward due to the weight of the litter bin and the base, that is, the second support 20 will move upward relative to the first support 10; in this process, the second support 20 can push the contact 31 of the load sensor 30, so that the load sensor 30 measures the weight of the base, the litter bin and the first support 10, and then subtracts the weight of the base, the first support 10 and the litter bin shell, so as to obtain the weight of the excrement and litter or the excrement, litter and cat inside the litter bin. Therefore, a gap space needs to be formed on the first support 10 for the relative movement of the second support 20.

[0091] In this embodiment, the elastic pad 40 can cover the gap between the first support 10 and the second support 20, prevent sundries from entering, and thus protect the gap, reduce the cleaning difficulty of the user, and avoid the accumulation of sundries affecting the weighing accuracy and the health of the pet and the user.

[0092] As an implementation, the first support 10 can be a connecting piece connected to the base or the bottom; for example, the first support 10 can be directly placed on the bottom, and the base is placed on the first support 10.

[0093] As an implementation, the first support 10 can be integrally arranged with the base, or the first support 10 serves as the base. In this embodiment, the second support 20, the load sensor 30 and the elastic pad 40 are all integrated on the first support 10, so that when assembling, the first support 10 is only needed to be placed on the bottom, so that the second support 20 abuts against the bottom, which is convenient and fast.

[0094] In one embodiment, the elastic pad 40 can be connected to the first support 10 through the mounting ring 41. In actual application, the elastic pad 40 can be connected to the mounting ring 41 through bonding or the like, and the inner end of the elastic pad 40 is connected to the second support 20; when assembling, the mounting ring 41 is only needed to be mounted on the first support 10, so as to complete the connection of the elastic pad 40 and the first support 10.

[0095] The elastic pad 40 can also be a separate component from the mounting ring 41; for example, when mounting, the mounting ring 41 is connected to the first support 10 through bolts or the like, and the elastic pad 40 is clamped and fixed between the mounting ring 41 and the first support 10, so as to complete the mounting of the elastic pad 40.

[0096] In another embodiment, please refer to Figure 3 andFigure 4 Further, a plurality of elastic arms 50 are provided. The plurality of elastic arms 50 are arranged around the outer periphery of the second support 20; the elastic arms 50 connect the first support 10 and the second support 20.

[0097] The elastic arms 50 can provide a reverse elastic force when the first support 10 and the second support 20 are twisted or the like, thereby reducing the amount of deviation between the first support 10 and the second support 20.

[0098] Specifically, taking the case of the weighing assembly being applied to a pet toilet as an example, the first support 10 is connected to the base of the pet toilet, and the second support 20 is connected to the bottom of the pet toilet. In actual application, the base and the bottom will deviate. For example, when a pet enters the sand bin, the pet will move in the sand bin, causing the center of gravity of the sand bin to deviate, thereby causing the base and the bottom to deviate. For another example, when the bottom is placed on an uneven support surface, the base will also deviate from the bottom. When the base and the bottom deviate, the weighing accuracy of the weighing sensor 30 will be affected.

[0099] In this embodiment, when the base and the bottom deviate, the elastic arms 50 will deform accordingly, thereby being able to provide a reset elastic force in the opposite direction of the deviation, reducing the amount of deviation of the base and the bottom, and ensuring the accuracy of the weighing.

[0100] In application, the second support 20 can extend outside the sealed area; therefore, the elastic arms 50 connected to the second support 20 can be arranged on the outer wall of the sealed area.

[0101] In this embodiment, the elastic arms 50 can be in the form of strips, so that they can deform in the vertical direction and also twist in the horizontal direction to adapt to the case of the base rotating horizontally relative to the bottom. Since a plurality of elastic arms 50 need to be arranged, there will be gaps between adjacent elastic arms 50. It should be noted that the plurality of elastic arms 50 can be integrally connected to form a meandering strip, which will also cause gaps in the elastic arms 50.

[0102] To this end, as a further improvement, as shown in Figure 3 The elastic arms 50 are arranged between the elastic pad 40 and the first support 10, i.e. the elastic arms 50 are arranged inside the sealed area.

[0103] Specifically, taking the case of the first support 10 being arranged above the weighing sensor 30 as an example, the second support 20 is arranged below the weighing sensor 30; the elastic arms 50 can be arranged on the top of the second support 20; and the elastic pad 40 is arranged below the elastic arms 50.

[0104] In this embodiment, the elastic pad 40 can cover the gap between the elastic arms 50 in addition to sealing the gap between the second support 20 and the first support 10, so as to prevent the gap between the elastic arms 50 from entering the sundries.

[0105] It should be noted that the second support 20 can move relative to the first support 10 following the deformation of the elastic arms 50, that is, when the base pushes the second support 20, the second support 20 can move upward to push the load sensor 30, and in this process, the elastic arms 50 deform upward following the second support 20.

[0106] In a further improved embodiment, please refer to Figure 3 , which further comprises a third support 90; the third support 90 is connected to the first support 10; the third support 90 is provided with a through hole 91; the second support 20 can slide through the through hole 91. That is, the third support 90 can guide the second support 20 to improve the stability of the sliding of the second support 20. The second support 20 passing through the through hole 91 can abut against the base.

[0107] Optionally, the outer periphery of the elastic arm 50 can be slidably connected to the third support 90 through a connecting piece.

[0108] Since the second support 20 and the third support 90 are slidably connected, the same gap will exist between the second support 20 and the third support 90.

[0109] Therefore, in one embodiment, the load sensor 30, the first support 10, the second support 20 and the third support 90 are all arranged on the same side of the elastic pad 40, that is, the third support 90 is also arranged in the sealed area. As Figure 4 shown in the embodiment schematic diagram, the load sensor 30, the first support 10, the second support 20 and the third support 90 are all arranged above the elastic pad 40, and in this way, the elastic pad 40 can simultaneously shield the gap between the second support 20 and the third support 90, the gap between the second support 20 and the first support 10, and the gap between the plurality of elastic arms 50.

[0110] In the case that the pet product is not prone to deviation, or in the case that other deviation mitigation structures are provided, the load assembly can also not be provided with elastic arms. As Figure 1As shown, the elastic pad 40 can be arranged around the outer periphery of the second support 20; the second support 20 is connected to the first support 10 through the elastic pad 40. In this case, the second support 20 is movable relative to the first support 10 through the connection of the elastic pad 40; meanwhile, since the elastic pad 40 is arranged around the second support 20, the outer periphery of the second support 20 can be elastically supported by the elastic pad 40 in all directions, so that in this embodiment, the third support 90 can not be arranged, and the elastic pad 40 can provide a guiding function for the second support 20.

[0111] On the basis of the above embodiment, as an implementation manner, the second support 20 is an elastic member and is arranged integrally with the elastic pad 40. Specifically, in this embodiment, the second support 20 can be made of rubber, silica gel or the like, and is arranged integrally with the elastic pad 40, so as to facilitate the manufacturing and installation of the elastic pad 40 and the second support 20.

[0112] It should be noted that the second support 20 and the elastic pad 40 can be in an integrated structure, which means that the elastic pad 40 is in a whole piece, and part of the elastic pad 40 serves as the second support 20 for abutting against the load cell 30.

[0113] In addition, the second support 20 and the elastic pad 40 in an integrated structure can also be applied to the following embodiments, for example, the following embodiment in which the rolling member 80 is arranged.

[0114] On the basis of the above embodiment, as another implementation manner, the second support 20 comprises a wear-resistant member 21; the wear-resistant member 21 abuts against the load cell 30. The wear-resistant member 21 can be a metal sheet or the like hard structure.

[0115] Specifically, in the case where the second support 20 is an elastic member, the second support 20 is easily worn by long-term contact with the convex point 31 of the load cell 30. In this embodiment, the use of the wear-resistant member 21 can increase the wear resistance of the second support 20.

[0116] In application, please refer to Figure 1 The inner ring of the elastic pad 40 can be provided with a support ring 22, and the wear-resistant member 21 is arranged in the support ring 22. The support ring 22 has a hardness greater than that of the elastic pad 40, and can be used to support the wear-resistant member 21.

[0117] In one embodiment, the second support 20 is a foot pad, and the second support 20 is provided with a wear-resistant member 21; the wear-resistant member 21 abuts against the load cell 30.

[0118] Specifically, the second support 20 can be a rubber foot pad or the like structure with buffering capability, and cooperates with the wear-resistant member 21 to make the second support 20 have the characteristics of buffering and wear resistance.

[0119] In one embodiment, referring to Figure 1 , the first support 10 is provided with a groove 11; the load sensor 30 is arranged in the groove 11; and the elastic pad 40 and the second support 20 seal the groove 11.

[0120] As described above, the first support 10 can be used as a load support in pet products, that is, the sand bin base described above. By arranging the groove 11, the first support 10, the second support 20, the load sensor 30 and the elastic pad 40 can be integrated in the groove 11, which is convenient for manufacturing and product modularization; at the same time, after the elastic pad 40 and the second support 20 seal the groove 11, the groove 11 can also protect other components.

[0121] In actual application, the load assembly can include a plurality of load sensors 30 and a plurality of first supports 10. By arranging the groove 11, the plurality of first supports 10 can be independently arranged after the load sensor 30 is installed, and then installed on different products according to actual production needs.

[0122] As an implementation, referring to Figure 1 , the elastic pad 40 includes a corrugated section with a wavy cross section. Specifically, the elastic pad 40 can be partially corrugated or entirely corrugated. By arranging the corrugated section, the deformation capacity of the elastic pad 40 can be increased.

[0123] In other embodiments, referring to Figure 5 or Figure 6 , the load assembly provided by the embodiment further includes a base 60 and a pedestal 70; the first support 10 is connected to one of the base 60 and the pedestal 70, the load sensor 30 is connected to the other one of the base 60 and the pedestal 70, and the second support 20 abuts the other one of the base 60 and the pedestal 70.

[0124] The pedestal 70 can be used to support a sand bin; and the base 60 can be provided with a plurality of legs 62 for mounting the pedestal 70.

[0125] For ease of illustration, in the embodiments of the present application, the first support 10 is connected to the pedestal 70, the second support 20 abuts the base 60, and the load sensor 30 is connected to the base 60 through the second support 20.

[0126] As shown in Figure 5 , the first support 10 can be integrally arranged with the pedestal 70, and the pedestal 70 can be connected with a plurality of load sensors 30.

[0127] As shown in Figure 6 , the first support 10 can be arranged separately from the pedestal 70.

[0128] Optionally, the number of the load sensors 30 and the number of the feet 62 can be four, and the load sensors 30 are arranged at positions corresponding to the positions of the feet 62.

[0129] In a further improved embodiment, referring to Figures 7 to 9 , the first support 10 is arranged integrally with the base 70. One of the base 60 and the base 70 is provided with a convex column 61, and the other of the base 60 and the base 70 is provided with a clamping groove 71; the convex column 61 is clamped into the clamping groove 71; the outer side of the convex column 61 and / or the inner side of the clamping groove 71 is provided with a rolling member 80; the rolling member 80 is used to abut against the inner side of the convex column 61 and the clamping groove 71; and the rolling member 80 is arranged rollably at least in the vertical direction.

[0130] Specifically, when the base 70 and the base 60 are relatively offset, the rolling member 80 can abut against the inner side of the convex column 61 and the clamping groove 71 at the same time, so as to reduce the friction between the base 70 and the base 60 at this time; when the base 70 and the base 60 are not offset, the rolling member 80 can only contact one of the convex column 61 and the inner side of the clamping groove 71.

[0131] For example, the clamping groove 71 is arranged on the base 70, and the convex column 61 is arranged on the base 60. After the base 60 and the base 70 are connected to each other, the convex column 61 extends into the clamping groove 71, so that the rolling member 80 abuts against the inner side of the convex column 61 and the clamping groove 71 at the same time.

[0132] In actual application, when the pet enters the sand bin, the base 70 will be tilted and offset; for example, the pet moves to the left side of the sand bin, and the left side of the base 70 will sink relative to the right side. In the existing pet toilet, the base 70 and the base 60 are generally in direct abutment mode for contact. When the base 70 is offset, the direct abutment mode will cause a large friction between the base 70 and the base 60, and this part of the friction will affect the measurement accuracy of the load sensor.

[0133] In the embodiment, by arranging the rolling member 80 which is rollable at least in the vertical direction, the rolling member 80 can roll when the base 70 is offset, that is, the contact friction between the base 70 and the base 60 can be changed to rolling friction, so as to reduce the friction between the base 70 and the base 60, and further reduce the weighing interference caused by the contact between the base 70 and the base 60, and ensure the weighing accuracy of the load sensor.

[0134] It should be noted that, in the case of arranging the rolling member 80, the load assembly can not be provided with the elastic arm 50; that is, in the embodiment, the rolling member 80 can avoid the influence on the weighing caused by the offset of the base 70, so that the elastic arm 50 for buffering and resetting the offset can not be arranged, and the effects of simplifying the structure, reducing the production cost, and reducing the assembly difficulty can be achieved.

[0135] As an implementation, a plurality of connecting columns 63 can be arranged on the base 60; the arrangement positions of the connecting columns 63 can correspond to the plurality of feet 62. On the first support 10 and / or the base 70, a plurality of connecting grooves 12 can be arranged; the connecting grooves 12 and the connecting columns 63 correspond to each other. When the base 60 and the base 70 are connected, the connecting columns 63 are clamped into the connecting grooves 12, so that the clamping connection of the base 60 and the base 70 can be achieved.

[0136] In this way, the rolling member 80 can be arranged on the outer side of the connecting column 63 and / or the inner side of the connecting groove 12, so that the contact friction between the base 60 and the base 70 can also be changed into rolling friction.

[0137] On the basis of the above embodiment, as an implementation, the weighing sensor 30 includes a plurality of. Correspondingly, the second support 20 includes a plurality of. The plurality of weighing sensors 30 are arranged in the plurality of connecting grooves 12 respectively. The plurality of second supports 20 correspondingly abut the plurality of connecting columns 63.

[0138] The connecting column 63 and the foot 62 are the support structure of the base 60 and the base 70, and the gravity of each component above the base 60 will act on the foot 62. In the present embodiment, the weighing sensor 30 contacts the connecting column 63 through the second support 20, so that the weight of the whole device can act more accurately on the weighing sensor 30, and the measurement accuracy is improved. At the same time, the plurality of weighing sensors 30 can more evenly share the weight of the whole device, thereby improving the consistency of the service life of the plurality of weighing sensors 30.

[0139] As a further improvement, the groove 11 in the above embodiment is arranged in the connecting groove 12.

[0140] Optionally, the connecting column 63 and the convex column 61 can be arranged simultaneously; the connecting groove 12 and the clamping groove 71 can be arranged simultaneously; the rolling member 80 is arranged on at least one of the connecting column 63 and the convex column 61 and / or the rolling member 80 is arranged on at least one of the connecting groove 12 and the clamping groove 71.

[0141] In one embodiment, the connecting column 63 and the convex column 61 can be the same structure; the connecting groove 12 and the clamping groove 71 can be the same structure; that is, the connecting column 63 can be used as the convex column 61; the connecting groove 12 can be used as the clamping groove 71, so that the base 60 and the base 70 do not need to be additionally provided with the convex column 61 and the clamping groove 71.

[0142] In the above embodiment, the outer side of the connecting column 63 and / or the inner side of the connecting groove 12 is used as the mounting surface of the rolling member 80. Taking the example that the rolling member 80 is arranged on the outer side of the connecting column 63, please refer to Figure 7 、 Figure 8 WithFigure 12 On the outer side of the connecting column 63, a circular groove 64 can be provided for mounting the rolling member 80, so that the rolling member 80 is partially placed in the circular groove 64 and partially protrudes outward relative to the connecting column 63, so that the rolling member 80 can abut against the inner side of the connecting groove 12. By providing the circular groove 64, the stability of the rolling member 80 after installation can be increased, and the rolling member 80 can be prevented from falling off by being separated from the connecting column 63.

[0143] Similarly, the circular groove 64 can also be provided on the inner side of the connecting groove 12.

[0144] Further, the rolling member 80 is in a spherical shape, so that the rolling member 80 can roll in the horizontal direction in addition to the vertical direction, so that when the base 70 rotates horizontally relative to the pedestal 60, the friction in the horizontal direction can be changed into kinetic friction, so that the influence of the horizontal direction deviation on the counterweight can be reduced.

[0145] In one embodiment, as shown in Figure 8 , the rolling member 80 is arranged on the outer side of the convex column 61 along the first direction and the outer side along the second direction, and / or the rolling member 80 is arranged on the inner side of the clamping groove 71 along the first direction and the inner side along the second direction; the first direction and the second direction intersect in the horizontal direction.

[0146] As shown in Figure 8 , the first direction can be the positive and negative directions of the x-axis in Figure 8 ; the second direction can be the positive and negative directions of the y-axis in Figure 8 .

[0147] Optionally, the first direction and the second direction are perpendicular to each other.

[0148] Specifically, the base 70 and the pedestal 60 can be in contact in multiple directions and can also be offset in multiple directions. For example, due to pets or placement, when the base 70 is offset relative to the pedestal 60 in the negative direction of the x-axis in Figure 8 , the distance between the side of the convex column 61 along the negative direction of the x-axis and the clamping groove 71 increases, so that the rolling member 80 on the side of the convex column 61 along the negative direction of the x-axis cannot contact the clamping groove 71, and at this time, the rolling member 80 along the positive and negative directions of the y-axis and the rolling member 80 along the positive direction of the x-axis can ensure that the base 70 and the pedestal 60 are still in rolling friction.

[0149] That is, in the embodiment, the rolling member 80 is arranged in the intersecting first direction and second direction, and the rolling member 80 is in a spherical shape, so that the friction between the base 70 and the pedestal 60 in each direction can be changed into rolling friction.

[0150] Please refer to Figure 10 and Figure 11The second aspect of the present application provides a weighing assembly, comprising: a first support 1, a second support 2, and a weighing sensor 3.

[0151] The second support 2 is movably arranged on the first support 1; the second support 2 comprises a central part 2-1 and an annular part 2-2 surrounding the outer periphery of the central part 2-1; the annular part 2-2 is an elastic member; a plurality of spaced-apart recesses 2-3 are arranged on the annular part 2-2; a resilient arm 2-4 is formed between adjacent two recesses 2-3; the weighing sensor 3 is arranged on the central part 2-1 and abuts against the second support 2.

[0152] In the embodiment, the central part 2-1 serves as a connecting member of the weighing sensor 3 and can be used to connect the main support such as the base 60. Since the annular part 2-2 is elastic, the central part 2-1 can move relative to the first support 1 through the deformation of the annular part 2-2.

[0153] In the central part 2-1, the recesses 2-3 do not penetrate the annular part 2-2, so the annular part 2-2 can play a role in connecting and sealing the space between the central part 2-2 and the first support 1. At the same time, the resilient arm 2-4 is formed between adjacent two recesses 2-3; the elastic modulus of the resilient arm 2-2 is greater than that of the recess 2-3 part, so the resilient arm 2-2 can serve as a buffer reset member when the first support 1 is offset relative to the central part 2-2. After the first support 1 is connected to the base 70, the resilient arm 2-2 can provide a buffer and reset elastic force for the offset of the base 70, avoiding the influence of the offset of the base 70 on the weighing sensor 3.

[0154] In the embodiment, the outer periphery of the second support 2 can be sealingly connected to the first support 1 by bolts or other connecting members.

[0155] Further, the first support 1 is provided with a recess 1-1; the weighing sensor 3 is arranged in the recess 1-1; and the second support 2 seals the recess 1-1.
