The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0031] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] In order to make the person in this technology field better understand the utility model scheme, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings.

[0033] Referring to the accompanying drawings Figure 1 - the accompanying Figure 6 The embodiment discloses a handheld electronic scale which comprises a handle 1, a scoop 2 and a weighing assembly 3. The handle 1 is internally provided with a mounting cavity 10, and the handle 1 is internally provided with a control assembly 11. The weighing assembly 3 comprises a first strain sensor 31, a second strain sensor 32 and a connecting piece 30. The first strain sensor 31 and the second strain sensor 32 are both fixed in the mounting cavity 10, and the first strain sensor 31 and the second strain sensor 32 are arranged in an upper and lower spaced-apart and mutually parallel manner. One end of the connecting piece 30 is attached to the first strain sensor 31, and the other end of the connecting piece 30 extends out of the mounting cavity 10 and is fixedly connected with the scoop 2. The first strain sensor 31 and the second strain sensor 32 are electrically connected with the control assembly 11.

[0034] Specifically, the control assembly 11 comprises a control panel 110, a display screen 111 and a battery. The display screen 111 is embedded on the outer wall of the handle 1, and the control panel 110 and the battery are both fixed in the mounting cavity 10. The control panel 110 is electrically connected with the battery, the display screen 111, the first strain sensor 31 and the second strain sensor 32. The control panel 110 is a pcb circuit board integrated with a computing chip. In the embodiment, the first strain sensor 31 and the second strain sensor 32 are both resistance strain sensors, and the weighing purpose is achieved through resistance value change. The first strain sensor 31 and the second strain sensor 32 are mutually spaced apart so as not to interfere with each other, and the first strain sensor 31 and the second strain sensor 32 are mutually parallel so as to have a specific coefficient alpha between them at a set position. In actual application, the initial weight A1 of the articles in the scoop 2 is obtained by contacting the first strain sensor 31 with the connecting piece 30. Since the second strain sensor 32 is also arranged on the handle 1, the second sensor obtains the reference weight A2 when the scoop 2 contains articles. When the handle 1 is at different inclination angles and the scoop 2 contains the same articles, A1 and A2 will also change differently. Since the relative positions of the first strain sensor 31 and the second strain sensor 32 remain unchanged, the specific coefficient alpha will not change. Finally, the control panel 110 calculates the specific coefficient alpha, the initial weight A1 and the reference weight A2 according to a specified formula to obtain the actual weight S of the articles in the scoop 2 displayed on the display screen 111. In the embodiment, the corresponding formula is as follows:

[0035] Actual weight S = initial weight A1 ÷ [(specific coefficient alpha + reference weight A2) ÷ specific coefficient alpha]

[0036] Wherein, the specific coefficient a can be set as 5, 10, 15, etc. according to the distance between the first strain sensor 31 and the second strain sensor 32, thus, the control panel 110 can calculate the actual weight of the objects in the bucket 2 by obtaining the values of the first strain sensor 31 and the second strain sensor 32, and the user does not need to swing the bucket 2 to the horizontal position to read the value, and the display screen 111 of the handheld electronic scale can accurately display the actual weight of the objects in the bucket 2 when the bucket 2 is inclined at a certain angle.

[0037] In summary, the first strain sensor 31 and the second strain sensor 32 are arranged in parallel and spaced apart from each other, and the control assembly 11 can output the actual weight of the objects in the bucket 2 by obtaining the corresponding values of the first strain sensor 31 and the second strain sensor 32, and the relative position between the first strain sensor 31 and the second strain sensor 32 remains unchanged, so that the control assembly 11 can accurately display the actual weight of the objects in the bucket 2 even when the bucket 2 is inclined at a certain angle, thereby solving the problem that the traditional electronic scale cannot accurately display the actual weight of the objects when the user holds it at an angle.

[0038] In the embodiment, the connecting piece 30 is a metal piece, the connecting piece 30 has an L-shaped structure, the connecting piece 30 includes a first connecting plate 301 connected with the first strain sensor 31 and a second connecting plate 302 connected with the bucket 2, the connecting piece 30 is made of sheet metal, which is convenient for processing and ensures the connection strength and stability, wherein the first connecting plate 301 is attached to the first strain sensor 31 by bolts, and the second connecting plate 302 can be connected with the bucket 2 in a plug-in manner, specifically, the bucket 2 is provided with a connecting hole 20, the bottom of the connecting hole 20 is provided with a plurality of limiting blocks 200, and the second connecting plate 302 is provided with a plurality of limiting grooves 3021, when the second connecting plate 302 is inserted into the connecting hole 20, the plurality of limiting blocks 200 are correspondingly clamped into the plurality of limiting grooves 3021, the plug-in connection of the second connecting plate 302 with the connecting hole 20 facilitates the replacement or disassembly of the bucket 2 for cleaning, the limiting groove 3021 and the limiting block 200 are embedded, so that the second connecting plate 302 does not shake left and right after being inserted into the connecting hole 20, thereby avoiding interference caused by the change of the resistance value of the first strain sensor 31, and ensuring that the display screen 111 of the control assembly 11 can accurately display the actual weight in the bucket 2.

[0039] As shown in Figure 5 the two opposite side walls of the connecting hole 20 are also provided with clamping protrusions 201 for clamping the second connecting plate 302, and the plurality of clamping protrusions 201 clamp the plate surface of the second connecting plate 302 from front to back, thereby further enhancing the connection stability of the connecting piece 30 and the bucket 2.
