Description

Technical Field

[0001] The utility model relates to a gas cooker, in particular to a scale body and a weighing gas cooker. Background Art

[0002] With the progress of science and technology and the development of economy, the application of weighing function is becoming more and more popular. It is not only very popular in measurement, but also more and more electrical products are popularizing this function. The weighing system is mainly composed of weighing platform, weighing sensor, load-bearing column and weighing display screen.

[0003] The weighing sensor currently used in weighing gas stoves converts the deformation of the strain gauge caused by the weight of the object into a resistance value, and reflects the weight of the object by collecting current or voltage information.

[0004] However, in the actual working process, weighing errors often occur during use: when weighing an object, if the weighing platform is tilted, the gravity of the object is decomposed into a downward force and a force parallel to the inclined plane, resulting in the measured weight being less than the actual weight, resulting in inaccurate weighing.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0025] Figure 1 The embodiment of the utility model provides a cross-sectional structural diagram of a scale body. The scale body provided by the embodiment of the utility model can be applied to weigh gas stoves, meet the requirements of food ingredient weighing accuracy, and enable the weighing system to be widely used on stoves. Figure 1 As shown, the scale body includes a load-bearing column 11 and a pressure head 12. A first matching structure 111 is provided at one end of the load-bearing column 11 adjacent to the pressure head 12, and a second matching structure 121 is provided at one end of the pressure head 12 adjacent to the load-bearing column 11. The first matching structure 111 cooperates with the second matching structure 121 to achieve the connection between the load-bearing column 11 and the pressure head 12. In a common embodiment, the pressure head 12 is located at the upper end of the load-bearing column 11. Under the influence of gravity, the weight of the pressure head 12 itself and the weight of the object carried on the pressure head 12 are applied to the load-bearing column 11, so that the load-bearing column 11 and the pressure head 12 are pressed and fixed due to gravity. In other embodiments, the pressure head 12 can also be located at the lower end of the load-bearing column 11; or the pressure head 12 is provided at both the upper end and the lower end of the load-bearing column 11.

[0026] refer to Figure 1 , the first matching structure 111 is provided with a protrusion 22, and the second matching structure 121 is provided with a groove 21. The protrusion 22 is at least partially located in the groove 21. Thus, through the matching of the protrusion 22 and the groove 21, the first matching structure 111 and the second matching structure 121 are matched, so as to realize the connection between the load-bearing column 11 and the pressure head 12. It can be understood that, usually limited by the radial size of the load-bearing column 11, the radial size of the load-bearing column 11 will not be very large, so it is more preferred to set the protrusion 22 in the first matching structure 111 on the load-bearing column 11. Of course, in other alternative embodiments, the groove 21 can also be set in the first matching structure 111 on the load-bearing column 11, and the protrusion 22 can be set in the second matching structure 121 of the pressure head 12. In this way, one of the first matching structure 111 and the second matching structure 121 is provided with a groove 21, and the other is provided with a protrusion 22. That is, the matching of the protrusion 22 and the groove 21 can be achieved.

[0027] The embodiment of the utility model provides a scale body, which is used for weighing gas stoves. A protrusion 22 is set at one end of the load-bearing column 11 near the pressure head 12, and a groove 21 is set at one end of the pressure head 12 near the load-bearing column 11; or, a groove 21 is set at one end of the load-bearing column 11 near the pressure head 12, and a protrusion 22 is set at one end of the pressure head 12 near the load-bearing column 11. The groove 21 and the protrusion 22 match each other. Reduce the degree of inaccurate weighing. The scale body provided by the utility model has a simple structure, is easy to install and maintain, and has the characteristics of high weighing accuracy, long service life and high cost performance.

[0028] Optionally, refer to Figure 1 , the groove 21 includes a concave surface 211, and the inner surface of the groove 21 includes the concave surface 211. The concave surface 211 may include, for example, at least one of a sphere, an ellipsoid, a hyperboloid, and a parabola. The protrusion 22 includes a convex surface 221, and the outer surface of the protrusion 22 includes a convex surface 221. The convex surface 221 may include, for example, at least one of a sphere, an ellipsoid, a hyperboloid, and a parabola. The surface types of the concave surface 211 and the convex surface 221 may be the same or different. For example, the concave surface 211 is a spherical surface, the convex surface 221 is a spherical surface, and the surface types of the concave surface 211 and the convex surface 221 are the same. Alternatively, the concave surface 211 is an ellipsoid, the convex surface 221 is a spherical surface, and the surface types of the concave surface 211 and the convex surface 221 are different. The vertex of the convex surface 221 abuts against the vertex of the concave surface 211. The vertex of the convex surface 221 is the center point of the convex surface 221, and is also the highest point on the protrusion 22. The vertex of the concave surface 211 is the center point of the concave surface 211, and is also the lowest point on the groove 21. In the embodiment of the utility model, the protrusion 22 is at least partially located in the groove 21, and the groove 21 and the protrusion 22 are matched by the cooperation of the convex surface 221 on the protrusion 22 and the concave surface 211 on the groove 21. The highest point on the protrusion 22 abuts against the lowest point on the groove 21. Thus, at least through the contact between the highest point on the protrusion 22 and the lowest point on the groove 21, the weight of the pressure head 12 itself and the weight of the object carried on the pressure head 12 are supported, so that the load-bearing column 11 and the pressure head 12 are pressed and fixed due to gravity.

[0029] Optionally, refer to Figure 1 The convex surface 221 can be a convex spherical surface, and the concave surface 211 can be a concave spherical surface. The spherical surface processing technology is a mature processing technology with low process difficulty. Setting the convex surface 221 as a convex spherical surface and the concave surface 211 as a concave spherical surface can reduce the process difficulty of processing and reduce the difficulty of making the scale body.

[0030] Optionally, refer to Figure 1, the concave curved surface 211 is a concave spherical surface, and the convex curved surface 221 is a convex spherical surface, and the diameter of the concave spherical surface is greater than the diameter of the convex spherical surface. The load-bearing column 11 and the pressure head 12 are connected by two spherical surfaces, the upper end surface of the load-bearing column 11 is a convex spherical surface, and the lower end surface of the pressure head 12 is a concave spherical surface. Wherein, the diameter of the concave spherical surface is greater than the diameter of the convex spherical surface, so that the concave spherical surface of the pressure head 12 is just buckled on the convex spherical surface of the load-bearing column 11, and the center of the convex spherical surface is the same center as the concave spherical surface. The diameter of the concave spherical surface is greater than the diameter of the convex spherical surface, thereby providing a space for the convex spherical surface to allow slight shaking in the cavity formed by the concave spherical surface. When the weighing platform is slightly deflected under external multiple factors, the pressure head 12 shakes slightly relative to the load-bearing column 11, and the contact point between the pressure head 12 and the load-bearing column 11 is no longer the vertex of the convex curved surface 221 and the vertex of the concave curved surface 211. However, since the cavity formed by the concave spherical surface provides a space for the convex spherical surface to allow slight shaking, the vertex of the convex curved surface 221 is the highest point on the protrusion 22, and the vertex of the concave curved surface 211 is the lowest point on the groove 21. During the slight shaking process, the highest point on the protrusion 22 is automatically abutted against the lowest point on the groove 21, and the vertex of the convex curved surface 221 is restored to the state of abutting against the vertex of the concave curved surface 211, so that the vertex of the convex spherical surface is always aligned with the center line of the pressure head 12. This reduces the degree of inaccurate weighing and improves the weighing accuracy of the scale.

[0031] Figure 2 Schematic diagram of the cross-sectional structure of another scale body provided by the embodiment of the utility model, such as Figure 2 As shown, the protrusion 22 includes a main body 222 and a protrusion 223, and the protrusion 223 is connected to the main body 222. The radial dimension of the protrusion 223 is smaller than the radial dimension of the main body 222. The radial dimension is the dimension perpendicular to the extension direction of the protrusion 22. When the cross-sections of the protrusion 223 and the main body 222 are circular, the radial dimension is the diameter. In one embodiment, the protrusion 223 and the main body 222 are integrally formed. For example, the protrusion 223 and the main body 222 are formed by removing a portion of the end of a cylinder and reducing the diameter of the end of the cylinder. The connecting surface of the main body 222 and the protrusion 223 is formed as a mounting surface 224. The protrusion 223 is located in the groove 21, and the top of the side wall of the groove 21 abuts against the mounting surface 224. In the embodiment of the utility model, the matching of the groove 21 and the protrusion 22 is achieved by the matching of the mounting surface 224 on the protrusion 22 and the top of the side wall. Thus, at least the top of the side wall of the groove 21 contacts the mounting surface 224, supporting the weight of the pressure head 12 itself and the weight of the object carried on the pressure head 12, so that the load-bearing column 11 and the pressure head 12 are pressed and fixed by gravity. The load-bearing column 11 and the pressure head 12 are connected by plane-to-plane matching.

[0032] Optionally, refer to Figure 2, the length of the protrusion 223 is less than the depth of the groove 21. The top of the protrusion 223 does not contact the bottom of the groove 21, and the bottom of the groove 21 does not contact the top of the protrusion 223, so that the weight of the pressure head 12 itself and the weight of the object carried on the pressure head 12 are borne by the contact surface between the top of the side wall of the groove 21 and the installation surface 224. The protrusion 223 is introduced into the groove 21 of the load-bearing column 11, and the weighing plate 32 is stable after installation to prevent the weighing plate 32 from tipping over.

[0033] For example, reference Figure 2 , the radial dimension of the protrusion 223 in the pressure head 12 is smaller than the radial dimension of the groove 21 in the load-bearing column 11. In other embodiments, the radial dimension of the protrusion 223 in the pressure head 12 can also be equal to the radial dimension of the groove 21 in the load-bearing column 11.

[0034] Optionally, refer to Figure 2 The side of the groove 21 is a guide surface. The side of the groove 21 plays a guiding role, guiding the protrusion 223 at the lower end of the pressure head 12 to be introduced into the groove 21 of the load-bearing column 11, so that the top of the side wall of the groove 21 abuts against the installation surface 224, so that the pressure head 12 and the load-bearing column 11 are guided when being installed, which is convenient for installation.

[0035] For example, reference Figure 2 The groove 21 includes a side surface and a bottom surface. The bottom surface is a plane. The side surface is perpendicular to the bottom surface. The side surface of the groove 21 is a vertical guide surface. The side surface of the groove 21 limits the moving path of the protrusion 223 when the pressure head 12 and the load-bearing column 11 are installed, thereby guiding the moving direction of the protrusion 223 when the pressure head 12 and the load-bearing column 11 are installed.

[0036] Figure 3 is a schematic diagram of the cross-sectional structure of another scale body provided by the embodiment of the utility model, referring to Figure 1-Figure 3 The scale body further includes a weighing sensor 31, which is located on the side of the load-bearing column 11 away from the pressure head 12. That is, the weighing sensor 31 is located at the lower end of the load-bearing column 11, and the pressure head 12 is located at the upper end of the load-bearing column 11, so that the weight of the load-bearing column 11 itself, the weight of the pressure head 12 itself, and the weight of the object carried on the pressure head 12 are applied to the weighing sensor 31, and the weighing sensor 31 weighs to obtain a specific weight value.

[0037] Optionally, refer to Figure 1-Figure 3The scale body includes a plurality of load-bearing columns 11, a plurality of pressure heads 12 and a plurality of weighing sensors 31. The number of load-bearing columns 11, pressure heads 12 and weighing sensors 31 is equal, and the three correspond to each other one by one. A pressure head 12 is provided at the upper end of each load-bearing column 11, and a weighing sensor 31 is provided at the lower end. There can be 3 or more load-bearing columns 11 and pressure heads 12, and the specific number is not limited. Using 3 or more weighing sensors 31 to form the scale body can reduce the local pressure of the total weight of the pots and ingredients above the pot rack on a single weighing sensor 31.

[0038] The scale body also includes a weighing plate 32, which is located on the side of the pressure head 12 away from the load-bearing column 11. The weighing plate 32 is located at the upper end of the pressure head 12. The weighing plate 32 is used to hold food ingredients waiting to be weighed. The weighing plate 32 is located at the upper end of multiple pressure heads 12 to reduce the local pressure on a single pressure head 12.

[0039] For example, reference Figure 3 The weighing sensor 31 is mounted on a fixing plate 34, and the fixing plate 34 is fixed on the bottom plate 33 of the cooker. The weighing sensor 31 is a cantilever beam structure weighing sensor. One end of the weighing sensor 31 is fixedly connected to the fixing plate 34, and the other end is connected to the load-bearing column 11 through a weighing foot 35.

[0040] Figure 4 This is a partial schematic diagram of a weighing gas stove provided by the embodiment of the utility model, referring to Figure 4 The weighing gas stove comprises the scale body in the above embodiment and the pot rack 42 arranged on the scale body. Thus, the weight of the pot rack 42 and the object carried thereon can be weighed by the scale body in the weighing gas stove.

[0041] For example, reference Figure 4 , a pot 41 can also be arranged on the pot rack 42. The pot 41 can be regarded as a weighing platform. Since the weight of the pot 41 and the ingredients added in the pot 41 and the objects to be weighed can be weighed by the weighing scale in the gas stove.
