Technical Field
[0001] The utility model relates to the technical field of electronic scales, in particular to a solar electronic scale that automatically powers on when weighing. Background Art
[0002] With the development of technology and the progress of society, electronic scales are widely used in many fields such as households, commerce, and industry due to their convenience and accuracy. Especially in daily life, people's demand for portable electronic scales that are convenient to use is increasing day by day. The common electronic scales on the market at present mainly include traditional plug-in electronic scales and handheld or desktop electronic scales powered by batteries.
[0003] However, the above types of electronic scales have some problems. First, most traditional electronic scales are powered by batteries, which not only increases the user's usage cost but also brings inconvenience to the user due to frequent battery replacement. Second, the disposal of waste batteries will also have a certain impact on the environment. Third, most electronic scales need to be manually turned on and off, especially after a long period of non-use, the user needs to manually find the switch position for operation, which is not user-friendly for some users with poor eyesight or poor hand flexibility. Fourth, when no item is being weighed, the electronic scale is still in the standby state, that is, the electrical components are always consuming electrical energy in standby. At present, there are also a small number of electronic scales with a momentary switch between the bottom case and the panel, which only power on the electronic scale when weighing an item, but there is also a problem: when weighing, the momentary switch will divide part of the pressure of the panel on the load cell, so that when the weight of the item being weighed is relatively light, the weighing is not very accurate.
[0004] The present utility model is made based on the above situation. Summary of the Utility Model
[0005] The utility model overcomes the deficiencies of the prior art and provides a solar electronic scale that automatically powers on when weighing. The electronic scale can be charged by solar energy and automatically cuts off the power when not in use; it automatically closes the control circuit only when weighing an item, thereby reducing energy consumption.
[0006] The present utility model is realized through the following technical solutions:
[0007] A solar electronic scale that automatically powers on when weighing, including a bottom case and a panel connected to the bottom case. A PCB board, a weighing module, a weight display module, and a solar panel for power supply are provided between the panel and the bottom case. The PCB board, the weighing module, the weight display module, and the solar panel are electrically connected to form a control circuit. A momentary switch is also provided between the panel and the bottom case, which can close the control circuit when an item to be weighed is placed on the panel and can disconnect the control circuit after the item to be weighed leaves the panel.

A limiting cover body for restricting the weighing sensor and the momentary switch from separating from the placement groove is further connected to the installation seat. The momentary switch is connected to the limiting cover body. The return spring is disposed between the weighing sensor and the limiting cover body.
[0011] A solar electronic scale that automatically powers on when weighing, as described above. The bottom case is in an "I" shape. The number of both the weighing sensor and the support foot is four and they are disposed at the four ends of the bottom case.

[0017] Compared with the prior art, the present utility model has the following advantages:
[0018] The electronic scale in this case uses a solar panel as the power source, which can be charged by sunlight, thereby reducing energy consumption, saving energy and protecting the environment. At the same time, a momentary switch is also installed inside the electronic scale. That is, when an object to be weighed is placed on the panel, the gravity presses the momentary switch to close the control circuit, and when the object to be weighed is removed from the panel, the control circuit will automatically disconnect, thus solving the problems of small power and high standby power consumption of solar electronic scales.
[0019] The momentary switch is installed between the weighing sensor and the panel. When an object to be weighed is placed on the panel, the pressure on the panel and the momentary switch all acts on the weighing sensor, and the force is concentrated, making the weighing of the electronic scale more accurate.
[0020] It automatically powers on when on the scale and automatically powers off when off the scale, eliminating the need for users to manually find the switch position for operation, thus facilitating the use of the electronic scale in this case by some users with poor eyesight or poor hand flexibility.

[0028] The following further describes the present invention in conjunction with the drawings:
[0029] As Figures 1 to 6A solar electronic scale that automatically powers on when weighing, comprising a bottom case 1 and a panel 2 connected to the bottom case 1. A PCB board 3, a weighing module, a weight display module, and a solar panel 4 for power supply are provided between the panel 2 and the bottom case 1. The PCB board 3, the weighing module, the weight display module, and the solar panel 4 are electrically connected to form a control circuit. A momentary switch 5 is also provided between the panel 2 and the bottom case 1, which can close the control circuit when an object to be weighed is placed on the panel 2 and can open the control circuit after the object to be weighed leaves the panel 2. A placement cavity 100 for accommodating various electrical components is provided on the bottom case 1. Of course, the object to be weighed here can be a human body or an item with a weight greater than the minimum weighing range of the electronic scale.
[0030] The electronic scale in this case uses the solar panel 4 as a power source, which can be charged by sunlight, thereby reducing energy consumption, being energy-saving and environmentally friendly. At the same time, a momentary switch 5 is also provided inside the electronic scale. That is, when an object to be weighed is placed on the panel, the momentary switch 5 will be pressed by gravity to close the control circuit. When the object to be weighed is removed from the panel, the control circuit will automatically open, thus solving the problems of small power and high standby power consumption of solar electronic scales. It automatically powers on when on the scale and automatically powers off when off the scale, eliminating the need for users to manually find the switch position for operation, which is convenient for users with poor eyesight or poor hand flexibility to use the electronic scale in this case.
[0031] In some embodiments, the weighing module includes a weighing sensor 61 provided inside the bottom case 1. The momentary switch 5 is provided between the weighing sensor 61 and the panel 2. A support foot 62 that can drive the weighing sensor 61 to press the momentary switch 5 when weighing is slidably connected to the bottom of the bottom case 1. A return spring 63 for resetting the weighing sensor 61 and the support foot 62 is provided between the support foot 62 and the panel 2.
[0032] The momentary switch 5 is provided between the weighing sensor 61 and the panel 2. When an object to be weighed is placed on the panel 2, the pressure on the panel 2 and the momentary switch 5 all acts on the weighing sensor 61, with the force concentrated, making the weighing of the electronic scale more accurate.
[0033] Specifically, the bottom case 1 is provided with a mounting base 11. The mounting base 11 is provided with a placement groove 110 that is open at the upper side. Inside the placement groove 110, a support foot 62, a weighing sensor 61, and a momentary switch 5 are sequentially placed from bottom to top. A through hole 111 for the lower part of the support foot 62 to pass through is provided at the bottom of the placement groove 110. The mounting base 11 is further connected with a limiting cover body 12 for restricting the weighing sensor 61 and the momentary switch 5 from detaching from the placement groove 110. The momentary switch 5 is connected to the limiting cover body 12, and the return spring 63 is arranged between the weighing sensor 61 and the limiting cover body 12. Among them, the mounting base 11 and the bottom case 2 are of an integral structure. The limiting cover body 12 is adhesively bonded to the bottom of the panel 2 through double-sided foam tape. Of course, the limiting cover body 12 can also be fixedly connected to the bottom case 1 through a connection structure such as a threaded fastener or a snap structure.
[0034] Further, the upper end of the support foot 62 is connected with a slider 621 that can slide up and down along the placement groove 110. The size of the slider 621 is larger than that of the through hole 111. The lower part of the support foot 62 passes through the bottom case 1. The momentary switch 5 and the return spring 63 are both arranged between the weighing sensor 61 and the limiting cover body 12. When a heavy object is placed on the panel 2, the support foot 62 drives the weighing sensor 61 and the limiting cover body 12 to cooperate to press the momentary switch 5. After the heavy object is removed, the return spring 63 pushes the weighing sensor 61 and the support foot 62 to reset, so that the momentary switch 5 disconnects the control circuit. Among them, the slider 621 and the support foot 62 are of an integral structure. In one embodiment, the bottom of the support foot 62 is connected with an anti-slip pad 622. The bottom of the limiting cover body 12 is provided with a mounting post 121 for mounting the return spring 63 and a limiting groove 122 for placing the momentary switch 5.
[0035] In some embodiments, the bottom case 1 is in an "I" shape. The number of both the weighing sensor 61 and the support foot 62 is four, and they are arranged at the four ends of the bottom case 1, so that the electronic scale is more evenly stressed and can better maintain balance.
[0036] In some embodiments, the bottom case 1 is provided with a mounting groove 13 for mounting the solar panel 4. A buffer structure 7 is provided between the bottom of the mounting groove 13 and the solar panel 4. Among them, the buffer structure 7 can be a sponge pad. Of course, it can also be other buffer structures such as a soft rubber pad. The solar panel 4 is adhesively bonded to the sponge pad, and the sponge pad is adhesively bonded to the bottom of the mounting groove 13. The buffer structure 7 prevents the bottom case 1 from being deformed under pressure or the solar panel 4 from being damaged due to vibration or dropping.
[0037] In some embodiments, the weight display module includes a limit frame 81 connected to the bottom case 1, and a display screen 82 and a backlight panel 83 are arranged on one side of the limit frame 81 from top to bottom. Among them, the limit frame 81 is connected to the bottom case 1 by threaded fasteners. Of course, it can also be fixedly connected to the bottom case 1 by other connection methods such as bonding.
[0038] In some embodiments, a display window 21 is provided on the panel 2 corresponding to the position of the display screen 82, and a light-transmitting window 22 for sunlight to irradiate on the solar panel 4 is provided on the panel 2 corresponding to the position of the solar panel 4. The display window 21 and the light-transmitting window 22 can be blocked to prevent water and dust by a colorless and transparent film or glass.
[0039] In some embodiments, four electrode plates 9 for measuring body fat are connected to the upper surface of the panel 2, and the electrode plates 9 are electrically connected to the PCB board 3. Thus, the electronic scale has the function of measuring body fat. The electrode plates 9 can be bonded to the panel 2 by double-sided tape. Of course, they can also be connected to the panel 2 by other connection methods. The panel 2 is a glass panel 2, and a wire-passing hole 23 for threading is provided on the panel 2 corresponding to the position of the electrode plates 9.
