Description

[Technical field]

[0001] The utility model relates to a heat-insulating and anti-jump electronic scale. [Background Technology]

[0002] At present, electronic scales on the market, especially electronic coffee scales, need to place a coffee pot on the scale body, boil water and add coffee during use. The proportioning process takes more than three minutes, so it is easy for heat to be transferred to the sensor, causing the sensor to jump due to thermal creep, making the reading unstable. There are generally two methods to solve the problem of reading jumps caused by heat. One is to use a layer of 7-10mm thick or more silicone pad on the scale pan to significantly insulate the heat, but there is a problem that the silicone pad is thick and expensive, which increases the overall thickness of the scale body and the thickness of the packaging box. Therefore, the product cost is increased, the product competitiveness is reduced, the burden on users is increased, and the shape is affected. In this method, the silicone pad accounts for more than 1 / 3 of the total thickness of the scale body, which is easy to cause the scale body to tip over; the second is to force the heat transfer to not jump or jump less through the software algorithm, but this method affects the accuracy of normal weighted weighing, resulting in problems such as sometimes weighted weight not being displayed or the display being insensitive, inaccurate, and lagging. It cannot accurately reflect the real-time increase or decrease of the current weighing in a timely manner, and the user experience is not good. [Contents of the utility model]

[0024] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one of the features.

[0026] like Figure 1-7 As shown, a heat-insulating and anti-jumping electronic scale includes a scale body 1, a scale pan 2 and a weighing sensor 3. One end of the weighing sensor 3 is connected to the scale body 1, and the other end of the weighing sensor 3 is connected to a supporting plate 4. At least one scale pan cavity is provided in the scale pan 2, and the supporting end of the supporting plate 4 is connected to the bottom surface of the scale pan cavity. The weighing sensor 3 is an aluminum alloy weighing sensor with a low temperature coefficient and low thermal sensitivity. In practical applications, air is provided in the scale pan cavity or the scale pan cavity is placed in a vacuum state, and the low thermal conductivity air or vacuum in the scale pan cavity effectively prevents heat transfer. At the same time, the distance between the scale pan 2 and the weighing sensor 3 is increased by the supporting plate 4, and the heat is dissipated by the supporting plate 4, thereby reducing the heat radiation and heat conduction transferred to the weighing sensor 3, and reducing the influence of heat transfer on the weighing accuracy.

[0027] like Figure 2-3As shown, the weighing pan 2 includes a tray 21, a tray groove 22 is provided on the tray 21, a heat-conducting panel 23 is provided on the upper side of the tray 21, and the tray groove 22 and the heat-conducting panel 23 cooperate to form a weighing pan cavity. In practical applications, a groove cover plate 24 is covered on the tray groove 22, and the tray groove 22 and the groove cover plate 24 cooperate to form a weighing pan cavity; a groove boss 25 arranged around the tray groove 22 is provided on the inner side of the open end of the tray groove 22, and the groove cover plate 24 is arranged on the groove boss 25. In this case, the tray 21 is a plastic tray, and the heat-conducting panel 23 is a stainless steel panel. When weighing, heat can be dissipated through the stainless steel panel to reduce heat transfer.

[0028] like Figure 4-7 As shown, two weighing pan cavities are provided in the weighing pan 2, and the supporting sheet 4 is a "J"-shaped supporting sheet, the middle lateral part of the "J"-shaped supporting sheet is connected to the weighing sensor 3, and the lateral parts on both sides of the "J"-shaped supporting sheet are respectively connected to the bottom surfaces of the two weighing pan cavities. In practical applications, the bottom surface of the tray 21 is located between the two weighing pan cavities and is provided with a tray groove 22, the middle lateral part of the "J"-shaped supporting sheet is arranged in the tray groove 22, and the upper side surface of the middle lateral part of the "J"-shaped supporting sheet does not contact the bottom surface of the tray groove 22, the upper side surfaces of the lateral parts on both sides of the "J"-shaped supporting sheet are respectively connected to the bottom surfaces of the weighing pan cavities on both sides, and the lower side surface of the middle lateral part of the "J"-shaped supporting sheet is connected to the weighing sensor 3. Among them, the supporting sheet 4 is an iron sheet. When in use, the "J"-shaped supporting sheet pulls the distance between the heat source placed on the weighing pan 2 and the weighing sensor 3 to reduce heat transfer.

[0029] like Figure 1-2 As shown, a heat insulation pad 5 is provided on the upper side of the scale pan 2 to play a preliminary heat insulation role. In this case, the heat insulation pad 5 is a silicone heat insulation pad with a thickness of about 2-3 mm. At the same time, a plurality of grooves are provided on the heat insulation pad 5. When heated, air can escape upward and sideways from the grooves in time to take away the heat.

[0030] When used for weighing, the heat source is placed on the heat insulation pad 5. At this time, the silicone heat insulation pad plays a preliminary role in heat insulation, the stainless steel panel of the scale pan 2 plays a role in heat dissipation, the scale pan cavity on the scale pan 2 prevents heat transfer, the "X"-shaped support sheet increases the distance between the heat source and the aluminum alloy weighing sensor, and the "X"-shaped support sheet plays a role in heat dissipation. In combination with the aluminum alloy weighing sensor with low thermal sensitivity, the heat transferred to the weighing sensor is greatly reduced through the above-mentioned layers of heat conduction, radiation and other heat transfer barriers and attenuation. Therefore, a hot coffee pot will not quickly or obviously transfer heat to the weighing sensor when boiling water is poured on it for weighing, which minimizes the thermal creep of the weighing sensor, solves the problems of the number of weighing sensor jumps and unstable readings caused by heat, and greatly reduces the influence of heat on the weighing accuracy.

[0031] like Figure 2-3As shown in the figure, a paste layer 6 is provided between the tray 21 and the heat conduction panel 23. A paste layer groove 26 is provided on the upper side of the tray 21, and the paste layer 6 is arranged in the paste layer groove 26, so that the heat conduction panel 23 is stably arranged on the tray 21; the tray 21 is a U-shaped tray, and the heat conduction panel 23 is a U-shaped heat conduction panel matching the U-shaped tray, which blocks the side gap of the electronic scale and improves the aesthetics.

[0032] As Figure 6-7 shown in the figure, a support plate 7 for limiting the maximum deformation of the weighing sensor 3 and for heat dissipation is provided between the weighing body 1 and the weighing sensor 3, which can dissipate heat from the weighing sensor 3 and further reduce the influence of heat on the weighing accuracy; a weighing calculation and display module 8 connected to the weighing sensor 3 for calculating and displaying the weighed weight is arranged in the weighing body 1, and the weighing data of the weighing sensor 3 is displayed after being calculated by the weighing calculation and display module 8.

[0033] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or directly or indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
