[0025] The specific embodiments of this disclosure are described below with reference to the accompanying drawings.

[0026] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0027] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0028] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0029] To address the problem that existing technologies require food to be weighed separately before being packaged, which is a cumbersome process and causes inconvenience to users, this disclosure provides a weighing lunchbox.

[0030] like Figure 1 , 6 As shown, the weighing lunchbox includes a box body 1, a plate 11, a weighing element 12, and a display element 13. The box body 1 has at least two holding slots 14. The number of plates 11 is the same as the number of holding slots 14, and one plate 11 is placed in each holding slot 14. The weighing element 12 is set inside the box body 1, and the number is the same as the number of plates 11 and is set one-to-one with the plates 11. It is configured to measure the weight of the food in the corresponding plate 11. The display element 13 is set on the box body 1, and the number is the same as the number of weighing elements 12 and is electrically connected to the weighing elements 12. It is configured to display the measurement result of the corresponding weighing element 12.

[0031] Specifically, such as Figure 1 As shown, the upper surface of the weighing lunch box has multiple slots 14 for placing plates 11. In practical applications, the weighing lunch box can have five or six slots 14, with one plate 11 placed in each slot 14. These plates 11 can hold staple food, protein, vegetables, fruits, snacks, and soup respectively.

[0032] Before putting food into the plate 11, the user needs to place the plate 11 into the serving slot 14, then turn on the control switch 3 and press the zero button 5 to zero the data of the weighing element 12 when no food is put into the plate 11.

[0033] The user adds food to the plate 11. Since each plate 11 is equipped with a weighing element 12, the weighing element 12 transmits the weighing result to the display element 13, which displays the weight of the food in the corresponding plate 11 for the user's reference.

[0034] It should be noted that the display element 13 can be a low-power OLED / LCD digital display, etc. Figure 1 In this container, the display element 13 is located on the upper surface of the container 1 so that the user can see it when serving food. Of course, the display element 13 can also be located on the side of the container 1 according to actual needs. In addition, the upper surface of the display element 13 is also provided with a waterproof coating, such as by dripping a layer of waterproof glue on the upper surface of the display element 13 to prevent food juices from dripping onto the display element 13 and affecting its normal operation.

[0035] Specifically, the weighing container contains a control chip 17, which is electrically connected to both the display element 13 and the weighing element 12. After receiving the measurement data from the weighing element 12, the control chip 17 sends it to the display element 13 for display.

[0036] The weighing lunch box provided in this disclosure has a simple structure and is equipped with a weighing element 12 inside, which can weigh the food in the corresponding plate 11 separately. The measurement result of the weighing element 12 is displayed to the user by the display element 13 to realize feedback.

[0037] Since the plate 11 is placed directly in the holding slot 14 of the box body 1, the user can take it out for washing at any time. Therefore, food, especially soup, may enter the interior of the food box along the gap between the holding slot 14 and the plate 11.

[0038] Therefore, in one embodiment of this disclosure, the box body 1 is further provided with a retaining ring 141 that protrudes around the opening of the holding slot 14. For example... Figure 3 , 4As shown, the containment ring 141 is formed by the upward protrusion of the edge of the opening of the container 14, which can block liquids and food residues that fall on the container 1 and prevent them from entering the interior of the container.

[0039] like Figure 4 As shown, in one embodiment of this disclosure, the plate 11 has a skirt 111 extending outward from the opening. The skirt 111 is located above the retaining ring 141 and forms a vertical gap. The skirt 111 is higher than the upper surface of the box body 1, making it convenient for the user to remove the plate 11 from the serving slot 14 via the skirt 111. At the same time, when soup splashes out of the plate 11, the soup cannot fall into the gap between the serving slot 14 and the plate 11 due to the protection of the skirt 111, but instead falls along the skirt 111 to the area outside the retaining ring 141.

[0040] The dinner plate 11 disclosed herein is equipped with a skirt 111, which not only makes it easier for users to pick up and put down the plate, but also reduces the amount of food residue falling into the box body 1, thereby preventing the growth of bacteria.

[0041] In addition, the skirt 111 and the guard ring 141 have a gap in the vertical direction, which can ensure that the weight of the food in the plate 11 is entirely supported by the weighing element 12, thus ensuring the measurement accuracy of the weighing lunch box.

[0042] In one embodiment of this disclosure, the weighing lunch box further includes a first partition 15, the number of first partitions 15 being the same as the number of lunch plates 11. The first partitions 15 are disposed between the corresponding weighing element 12 and the lunch plate 11, and the upper surface of the first partition 15 abuts against the bottom of the lunch plate 11, and the lower surface is provided with a heat insulation column 151 protruding out, the free end of the heat insulation column 151 contacting the measuring end of the corresponding weighing element 12.

[0043] In practical applications, the weighing element 12 can be a weight measuring element such as a pressure sensor. However, ordinary pressure sensors will produce deviations in measurement results when the operating temperature is greater than 60°C. Therefore, the weighing lunch box provided in this disclosure is equipped with a first partition 15 to separate the plate 11 from the weighing element 12, so as to avoid the weight of the food in the plate 11 from affecting the normal operation of the weighing element 12 and improve the accuracy of the measurement results of the weighing lunch box.

[0044] To prevent the heat from the food in the plate 11 from being transferred to the weighing element 12 through the plate 11 and the first partition 15, thus affecting the measurement results of the weighing element 12, in one embodiment of this disclosure, the heat insulation column 151 is set as a hollow structure to block heat transfer, thereby ensuring the accuracy of the measurement by the weighing element 12.

[0045] In one embodiment of this disclosure, the weighing lunch box further includes a second partition 16 disposed inside the box body 1. The second partition 16 divides the box body 1 into an upper space and a lower space. The holding slot 14 and the first partition 15 are located in the upper space, and the weighing element 12 is disposed in the lower space. The second partition 16 has guide holes 161 in the same number as the weighing element 12. The measuring end of the weighing element 12 passes through the guide holes 161 and contacts the first partition 15.

[0046] Specifically, such as Figure 3 As shown, since the weighing lunchbox provided in this disclosure contains electronic components, to prevent moisture, such as water that the user did not dry after washing the plate 11, from entering the lunchbox and affecting the normal operation of the electronic components, this disclosure provides a second partition 16 inside the weighing lunchbox. The outer periphery of the second partition 16 is provided with a sealing ring to the inner wall of the box body 1. At the same time, the second partition 16 is provided with guide holes 161, the same number as the weighing elements 12. The measuring end of the weighing element 12 passes through the guide holes 161 and contacts the heat insulation column 151 of the first partition 15 to measure the weight of the food in the lunchbox.

[0047] Meanwhile, the opening of the guide hole 161 extends upward to form a convex ring, which blocks water from entering the upper space and prevents water from entering the lower space through the guide hole 161.

[0048] In addition, such as Figure 5 As shown, since the weight of the lunchbox and the food inside it is entirely applied to the weighing element 12, and the testing end of the weighing element 12 has a small area, the stability of the lunchbox cannot be guaranteed. In the weighing lunchbox provided in this disclosure, the upper surface of the first partition 15 abuts against the bottom of the plate 11 to increase the contact area with the plate 11. The heat insulation column 151 on the lower surface of the first partition 15 is inserted into the guide hole 161. Through the cooperation between the guide hole 161 and the heat insulation column 151, the stability of the plate 11 is improved.

[0049] In practical applications, to ensure the hygiene of the lunchbox, the second partition 16 and the first partition 15 need to be disassembled periodically for disinfection and sterilization. The weighing lunchbox 1 provided in this disclosure consists of a main body and a bottom plate, which are fixed together by bolts. When it is necessary to disassemble the first partition 15 and the second partition 16, the user can remove the bolts on the bottom plate and then remove the first partition 15 and the second partition 16 for disinfection.

[0050] In addition, such as Figure 3 As shown, the bottom surface of the base plate is also provided with anti-slip strips, which can be made of materials such as silicone to increase the friction between the weighing lunch box and the contact surface.

[0051] In one embodiment of this disclosure, the weighing lunch box further includes an anti-rotation mechanism, which includes a first mating part 152 disposed on the first partition 15 and a second mating part 162 disposed on the second partition 16. The first mating part 152 and the second mating part 162 cooperate to restrict the first partition 15 from rotating relative to the second partition 16.

[0052] like Figure 6 As shown, both the first mating part 152 and the second mating part 162 are configured as rectangular ring structures, and the first mating part 152 is sleeved around the second mating part 162. When the user moves the lunch box, the second mating part 162 on the second partition 16 can restrict the rotation of the first partition 15 relative to the second partition 16, ensuring the contact area between the first partition 15 and the plate 11, and ensuring the stability of the plate 11.

[0053] In one embodiment of this disclosure, a control chip 17 is also provided inside the housing 1. The control chip 17 is electrically connected to the display element 13 and the weighing element 12, and is configured to process the data measured by the weighing element 12 and transmit it to the display element 13. The control chip 17 is located in the lower space.

[0054] As mentioned above, the weighing lunch box provided in this disclosure is also equipped with a control chip 17. The control chip 17 is located in the lower space and is electrically connected to the display element 13 and the weighing element 12 to realize the control of the display element 13 and the weighing element 12.

[0055] In addition, the weighing meal box provided in this disclosure is also equipped with a rechargeable battery 7, a charging module 6, a power display module 4, a control switch 3, and the aforementioned zeroing button 5, all of which are electrically connected to the control chip 17.

[0056] Specifically, refer to Figure 6 The rechargeable battery 7 is mounted on the bottom plate of the box 1, and the bottom plate has a mounting slot for mounting the rechargeable battery 7 to fix the rechargeable battery 7. The rechargeable battery is electrically connected to the control chip 17 to provide power to the display element 13, the power display module 4, etc.

[0057] like Figure 8 As shown, the weighing lunch box provided in this disclosure is also equipped with a charging module 6. The charging port of the charging module 6 is located on the side of the box body 1. The charging module 6 is electrically connected to the control chip 17. Users can connect charging devices, such as charging cables, to the charging port of the charging module 6. The control chip 17 converts AC power into DC power, thereby charging the rechargeable battery 7.

[0058] like Figure 1As shown, the power display module 4 is also located on the side of the box 1 and is electrically connected to the control chip 17. It is used to display the power of the rechargeable battery 7. Users can determine whether the rechargeable battery 7 needs to be charged based on the display result of the power display module 4.

[0059] Control switch 3 is electrically connected to control chip 17 and is responsible for controlling the on / off state of the circuits of display element 13 and power display module 4. When the user is not using the weighing lunchbox, the circuits controlling display element 13 and power display module 4 can be cut off by control switch 3 to save power.

[0060] As mentioned above, the actual weight exerted on the weighing element 12 includes not only the weight of the food in the plate 1, but also the weight of the plate 1 itself and the first partition 15. Therefore, before placing food into the plate 1, the user needs to use the zeroing button 5, via the control chip 17, to reset the display data on the display element 13 to zero. Afterwards, when the user places food into the plate 1, the display element 13 will only display the weight of the food in the plate 1, providing a more intuitive display result for the user.

[0061] In one embodiment of this disclosure, the weighing meal box further includes a mounting plate 181 and mounting legs 182 disposed inside the box body 1. The mounting legs 182 are fixed to the bottom surface of the box body 1 and support and fix the mounting plate 181 so that there is a heat dissipation gap between the mounting plate 181 and the bottom surface. The control chip 17 is disposed on the mounting plate 181.

[0062] like Figure 6 As shown, the mounting plate 181 inside the weighing container is fixed to the bottom of the container body 1 via mounting legs 182, specifically, by means of bolt connection or other methods. The control chip 17 is mounted on the mounting plate 181, which elevates the control chip 17 so that it is not in contact with the bottom of the container body 1, creating a heat dissipation gap between the control chip 17 and the bottom surface of the container body 1, which is beneficial for heat dissipation. Simultaneously, the weighing element 12 is also mounted on the mounting plate 181, which bears the load for the weighing element 12.

[0063] In one embodiment of this disclosure, the weighing lunch box further includes a lid 2, which is configured to seal the upper opening of the box body 1 when closed with the box body 1. The inner wall of the lid 2 is provided with sealing rings 21 in the same number as the number of plates 11, and the sealing rings 21 seal the opening of the plates 11 when the lid 2 and the box body 1 are closed.

[0064] like Figure 7 , 8As shown, the weighing lunchbox provided in this disclosure also includes a lid 2, which is fixedly attached to the box body 1 by a latch 19. Specifically, the latch 19 includes a connecting arm and a roller. The connecting arm is an elastic element. Correspondingly, the upper surface of the lid 2 is provided with a groove. When the user applies force to rotate the connecting arm, the roller rolls into the groove on the upper surface of the lid 2. Under the action of the elastic force of the connecting arm, the lid 2 and the box body 1 are tightly attached together.

[0065] The lid 2 has a raised sealing ring 21 with the same number of plates as the inner part of the lid. The positions of these sealing rings 21 correspond one-to-one with the positions of the plates 11. This seals each food container when the lid 2 and the body 1 are closed, preventing the food in different food containers from mixing during the movement of the weighed food containers, thereby improving the user experience.

[0066] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
