Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0031] In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0032] Please refer toFigures 1 to 11 Now the electronic scale provided by the embodiments of the present application is described.

[0033] It can be understood that the electronic scale provided by the embodiments of the present application can be used for powder weighing, such as flour, coffee powder, milk powder, etc., and can also be used for tea, medicinal materials, condiments, etc. weighing, and can also be used for carrying containers for liquid weighing.

[0034] Reference Figures 1 to 5 , Figures 7 to 10 It can be understood that the electronic scale provided by the embodiments of the present application includes a top seat 10 and a bottom seat 20, the bottom seat 20 is arranged at the bottom of the top seat 10, and the top seat 10 and the bottom seat 20 are connected through a pressure sensor 30. When the top seat 10 carries the object to be weighed, the top seat 10 presses down the pressure sensor 30, so that the pressure sensor 30 obtains the weight change data.

[0035] Specifically, referring to Figure 1 , Figure 5 , Figure 8 and Figure 10 , in the height direction of the electronic scale, the orthographic projection area of the top seat 10 is greater than that of the bottom seat 20. In this way, when the top seat 10 and the bottom cover 12 are assembled and connected as an electronic scale, the top seat 10 can cover the bottom cover 12 to improve the aesthetic effect of the electronic scale.

[0036] Reference Figures 2 to 5 , Figures 7 to 10 In some embodiments, the top seat 10 includes a bottom cover 12 and a top cover 11 buckled on the bottom cover 12, and the top cover 11 and the bottom cover 12 are fixedly connected through fasteners (such as screws). A second sealing member 62 is arranged or formed between the outer side wall of the bottom cover 12 and the inner side wall of the top cover 11, which can be sealing glue or a special-shaped sealing ring. In actual application, the second sealing member 62 adopts a special-shaped sealing ring, and the contour shape of the special-shaped sealing ring is matched with the edge contour of the bottom cover 12.

[0037] A space for accommodating a power module 51, a control module 53 and a display module 52 is formed between the top cover 11 and the bottom cover 12. Among them, the power module 51 is used to power the control module 53 and the display module 52, and the power module 51 can be an internal rechargeable battery or a replaceable battery; the control module 53 is electrically connected with the pressure sensor 30 through a data line, and the data line is arranged through the bottom cover 12 to connect the control module 53 and the pressure sensor 30, so that the weight change data monitored by the pressure sensor 30 can be transmitted to the control module 53.

[0038] Specifically, referring to Figures 3 to 10The wire card 40 is injection molded on the data line. The wire card 40 is made of insulating material (for example, plastic) and has certain elasticity. Further, the first enclosure 121 is formed on the top of the bottom cover 12 (i.e., the side surface facing the interior space of the top base 10). The through space formed by the first enclosure 121 can limit the circumferential position of the wire card 40. The wire card 40 is inserted along the axial direction of the first enclosure 121 and fixed to the first enclosure 121. The wire card 40 can be in interference fit with the first enclosure 121, or can be inserted into the first enclosure 121 and fixed to the bottom cover 12 by fasteners, and the specific implementation is not limited thereto.

[0039] When the top base 10 is assembled, the power module 51, the control module 53, and the display module 52 are assembled on the top of the bottom cover 12. The pressure sensor 30 is connected to the bottom of the bottom cover 12. The data line is connected between the pressure sensor 30 and the power module 51. The wire card 40 is inserted and fixed in the first enclosure 121 to preliminarily fix the wire card 40 to the bottom cover 12. Then, the bottom cover 12 connected with the bearing plate 13 is fixed to the top cover 11 by fasteners, so as to complete the assembly of the top base 10. During the assembly process, the data line passing through the section of the top base 10 will not be displaced, and the data line perforation on the bottom cover 12 does not need to be glued. The simple assembly can achieve a good sealing effect.

[0040] Further, referring to Figure 8 and Figure 11 In some embodiments, the wire card 40 is provided with a recessed cavity 42 communicating between the adjacent two side surfaces of the bottom base 20. By providing the recessed cavity 42 on the bottom of the wire card 40, the recessed cavity 42 can reserve a space for the bending of the data line. The part of the data line not covered by the wire card 40 can be bent in the recessed cavity 42 to change the extension direction, so that the data line can be arranged close to the lower surface of the bottom cover 12. At the same time, the provision of the recessed cavity 42 can avoid the data line extending along the axial direction on the bottom of the wire card 40, so as to avoid the collision between the data line and the bottom base 20 when the top base 10 is pressed downward during the weighing operation.

[0041] Optionally, referring to Figure 5 , Figure 8 and Figure 10 In some embodiments, the top of the wire card 40 is spaced apart from the inner surface of the top side of the top base 10 (i.e., the inner surface of the top cover 11) by a gap; and / or, the bottom of the wire card 40 is spaced apart from the surface of the bottom of the top base 10 by a gap. Similarly, in this way, a space for the bending of the data line can be reserved. The part of the data line not covered by the wire card 40 can be bent to change the extension direction, so that the data line can be arranged at a certain vertical distance from the lower surface of the top cover 11.

[0042] It can be understood that there are various ways to assemble the line card 40 on the top base 10.

[0043] With reference to Figure 9 and Figure 10 In the first assembly mode, the line card 40 is inserted into the first enclosure 121 and then fixed to the bottom cover 12 by fasteners (e.g., screws). Specifically, threaded holes are provided on the bottom cover 12 on both sides of the first enclosure 121 and on the line card 40. After the line card 40 is inserted into the first enclosure 121 and fixed in the circumferential direction, screws are locked in the threaded holes to complete the fixation.

[0044] With reference to Figure 9 and Figure 10 In the first assembly mode, the line card 40 can be a straight column; or, a stepped portion 43 abutting against the bottom cover 12 and an insertion portion 44 inserted into the first enclosure 121 are formed on the line card 40. After the screws are locked, the stepped portion 43 presses the lower surface of the bottom cover 12 upward to achieve a better sealing effect.

[0045] With reference to Figures 2 to 8 In the second assembly mode, a bearing plate 13 is connected to the bottom cover 12, and the line card 40 is first fixed to the bearing plate 13 and then inserted into the first enclosure 121. Specifically, the bearing plate 13 is detachably connected to the bottom cover 12 by fasteners (e.g., screws, buckles, etc.). In actual application, the fasteners connecting the bearing plate 13 and the bottom cover 12 are screws, and threaded holes are provided on the bottom cover 12. The bearing plate 13 is used to connect the pressure sensor 30 and the bottom cover 12. Meanwhile, the data line is simultaneously threaded through the bearing plate 13 and the bottom cover 12, and the line card 40 is simultaneously fixed to the bearing plate 13 and the bottom cover 12. A notch 131 is provided on the bearing plate 13 and communicates with the side edge thereof. The notch 131 is used to enable the line card 40 on the data line to be inserted and slid into the depth direction of the notch 131, so that the line card 40 can be clamped and fixed to the bottom of the notch 131. Thus, the data line can be preliminarily fixed to the bearing plate 13 before being fixed to the bottom cover 12, thereby facilitating subsequent assembly.

[0046] With reference to Figure 8 and Figure 11 In the second assembly mode, the line card 40 can be a straight column; or, a stepped portion 43 abutting against the bottom of the bottom cover 12 and an insertion portion 44 inserted into the first enclosure 121 are formed on the line card 40. After the bearing plate 13 is fixed to the bottom of the bottom cover 12 by the fasteners, the stepped portion 43 of the line card 40 abuts against the lower surface of the bottom cover 12 under the action of the upward axial force to achieve a better sealing effect.

[0047] Further, in the second assembly mode, the peripheral wall of the wire card 40 is optionally provided with a clamping groove 41, which is used to be clamped on the bearing plate 13. Thus, after the wire card 40 is clamped on the bearing plate 13 at the gap 131, the axial position of the wire card 40 on the bearing plate 13 is also fixed.

[0048] In some embodiments, the bearing plate 13 is a metal plate, which can be made of stainless steel or aluminum alloy, for example. Thus, compared with plastic material, the metal material bearing plate 13 has better rigidity and can withstand larger loads without deforming. When the electronic scale is used to bear the container to weigh the mass of the liquid, the bearing plate 13 can also make the load of the top seat 10 and the weighing object concentrated on the pressure sensor 30, so that the top seat 10 can be kept in a horizontal position to effectively avoid the situation that one side of the top seat 10 is inclined relative to the base 20 under high load.

[0049] Further, referring to Figure 5 , Figure 6 and Figure 10 , on the basis of the above-mentioned embodiments, a first sealing member 61 is arranged or formed between the first enclosure 121 and the wire card 40. In actual application, the first sealing member 61 can be a sealing glue filled between the first enclosure 121 and the wire card 40, or a sealing ring sleeved on the peripheral side of the wire card 40 to extrude the inner wall of the first enclosure 121.

[0050] Referring to Figure 3 , Figure 7 and Figure 9 , in some embodiments, the lower surface of the bottom cover 12 is formed with a relief position 125 for accommodating the pressure sensor 30. Thus, the lower surface of the bottom cover 12 is arranged concave, which can accommodate the pressure sensor 30 to reduce the overall height of the electronic scale. Corresponding to the concave arrangement of the lower surface of the bottom cover 12, the control module 53 and the display module 52 are arranged on both sides of the length direction of the relief position 125 on the upper surface of the bottom cover 12, and the wire card 40 is arranged on one side of the width direction of the relief position 125.

[0051] Referring to Figure 3 , Figure 4 and Figure 6 , in some embodiments, a second enclosure 122 is arranged on the peripheral side of the bottom cover 12, which is arranged extending towards the top cover 11. The peripheral wall of the second enclosure 122 is provided with a sealing structure for accommodating a second sealing member 62. It can be understood that the sealing structure is a mounting groove 124 protruding from the outer surface of the second enclosure 122 to accommodate the second sealing member 62. Optionally, a reinforcing rib 123 is connected between the outer side wall of the mounting groove 124 and the peripheral wall of the second enclosure 122, which is arranged in an array along the circumference of the second enclosure 122.

[0052] The above merely provides preferred embodiments of the application, and is not used to limit the application. Any modification, equivalent replacement, and improvement made within the spirit and principle of the application shall fall within the protection scope of the application.
