[0036] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0037] Example 1

[0038] Reference Figures 1 to 9This embodiment provides an electronic kitchen scale, including a scale body 1, a host 2 and a thermometer 3. The thermometer 3 includes a detection end 30 and a connection end 31. The host 2 includes a display screen, a timer and a control chip. The host 2 is provided with a connection port 20. The connection end 31 of the thermometer 3 is electrically connected to the control chip through the connection port 20, and the control chip is electrically connected to the display screen and the timer.

[0039] The display screen is used to display the working conditions of the scale 1, the timer, and the thermometer 3. Specifically, the working condition of the scale 1 refers to the measured weight data, and the control chip receives the weight data and controls the weight data to be displayed on the display screen; the working condition of the timer refers to the prompted time data, and the control chip receives the time data of the timer and controls the time data to be displayed on the display screen; the working condition of the thermometer 3 refers to the measured temperature data, and the detection end 30 of the thermometer 3 is used to contact the object to be measured, obtain the temperature data of the object to be measured, and send the temperature data to the control chip, which receives the temperature data and controls the temperature data to be displayed on the display screen.

[0040] It should be noted that the timer has the functions of counting up and counting down, and corresponding buttons are provided on the display screen. The user can select the function of counting up or counting down according to cooking needs.

[0041] Preferably, when the thermometer 3 is not needed, a plug 201 is provided on the connection port 20 of the main unit 2 to prevent dust and moisture from entering the main unit 2 along the connection. When the thermometer 3 needs to be connected to the connection port 20, the plug 201 is removed from the connection port 20 and the connection end 31 of the thermometer 3 is inserted into the connection port 20.

[0042] Preferably, the scale body 1 and the host 2 are designed to be separated, and a wireless transmitting module and a weight detection module are provided inside the scale body 1, and a wireless receiving module is provided inside the host 2. The wireless transmitting module is connected to the wireless receiving module, and the weight detection module is connected to the wireless transmitting module. The weight detection module sends the detected weight information to the wireless transmitting module, and the wireless transmitting module sends the received weight information to the wireless receiving module.

[0043] Conventional electronic scales with an integrated scale body 1 and main unit 2 can block the display screen when weighing large items. Liquids or powders in the items can also cause stains to drip onto the display screen, making it difficult for the user to see the screen. However, this embodiment separates the scale body 1 and main unit 2, allowing the main unit 2 to be placed in a wider area. Even when weighing large items, the weighing result is not blocked by the display screen.

[0044] Furthermore, a card slot 21 is provided at one end of the host 2, and a first magnet 211 is provided in the card slot 21. A connecting slot 10 is provided at one end of the scale body 1, and a protruding block 101 is provided in the connecting slot 10, and a second magnet 102 is provided inside the protruding block 101. The contour of the protruding block 101 is adapted to the contour of the card slot 21. When the user does not need to use the kitchen electronic scale provided by this embodiment, the protruding block 101 can be inserted into the card slot 21, and the first magnet 211 and the second magnet 102 are attracted by magnetic force, so that the host 2 and the scale body 1 are connected by magnetic attraction, which is convenient for storage.

[0045] In this embodiment, the model of the control chip is VKV2. In actual applications, other chips can be selected as substitutes.

[0046] In this embodiment, the scale body 1 is provided with a measuring plate 11 on its surface, with scale marks 111 provided on two adjacent edges of the measuring plate 11. The scale body 1 can simultaneously measure dimensions while weighing. When a user uses the electronic kitchen scale of this embodiment in a kitchen, they can measure the length and width of ingredients to determine whether the ingredients are of appropriate size so that they can be cooked to the best taste.

[0047] The scale body 1 includes an upper scale shell 12 and a lower scale shell 13. The upper scale shell 12 and the lower scale shell 13 are connected to form a first cavity, and the wireless transmission module and the weight detection module are arranged in the first cavity. The upper scale shell 12 is provided with a plurality of connecting columns 122, and the lower scale shell 13 is provided with a plurality of connecting holes 133. The connecting columns 122 are adapted to the connecting holes 133. By inserting the connecting columns 122 into the corresponding connecting holes 133, the initial connection between the upper scale shell 12 and the lower scale shell 13 is achieved, and then the upper scale shell 12 and the lower scale shell 13 are locked by a plurality of screws to form a stable connection relationship.

[0048] A first sealing member 14 is provided at the connection between the scale body lower shell 13 and the scale body upper shell 12. The scale body lower shell 13 is provided with a first groove 131, and the first sealing member 14 is disposed in the first groove 131. When the scale body upper shell 12 and the scale body lower shell 13 are connected, the first sealing member 14 can achieve a sealing effect to prevent moisture and dust from entering the interior of the scale body 1 along the connection.

[0049] A first PCB board 15 is disposed in the first cavity and is fixedly connected to the inner side of the scale upper shell 12 by screws. The first PCB board 15 is electrically connected to the wireless transmission module and the weight detection module. The first PCB board 15 is used to receive weight data detected by the weight detection module, convert the weight data into a data signal, and control the wireless transmission module to send the data signal to the wireless receiving module, which is ultimately displayed on the display screen.

[0050] The scale body's lower shell 13 is equipped with four scale feet 16, each connected by a rectangular line. Each scale foot 16 is equipped with a weight detection module, which is a load cell 163. The four load cells 163 can simultaneously measure the weight of an object, providing more comprehensive weight distribution information than a single sensor. By comprehensively processing the data from the four load cells 163, the actual weight of an object can be more accurately determined, reducing measurement errors caused by uneven object placement or shifted center of gravity.

[0051] In addition, the data of the four weighing sensors 163 can be verified with each other. When the data of a certain weighing sensor 163 deviates greatly from the data of other weighing sensors 163, it can be determined that the weighing sensor 163 may be faulty, and the fault information is fed back to the first PCB board 15. The first PCB board 15 controls the display of the error code on the screen, which helps the user to discover and repair the fault in time, thereby ensuring the accuracy and reliability of the kitchen electronic scale.

[0052] It is understood that the load cell in this embodiment is a half-bridge load cell, and those skilled in the weighing field are familiar with its operating principles. In another embodiment, a parallel beam load cell can be selected to replace the half-bridge load cell in this embodiment. Half-bridge load cells are a relatively mature technology in the industry and will not be described in detail here.

[0053] Furthermore, the scale foot 16 includes a silicone sleeve 161 and a silicone pressure ring 162. The silicone sleeve 161 is provided with an annular groove, and the silicone pressure ring 162 is embedded in the annular groove, forming a nested structure with the silicone sleeve 161. The scale body lower shell 13 is provided with a scale foot mounting hole 132 adapted to the silicone sleeve 161. The silicone sleeve 161 and the silicone pressure ring 162 seal the scale foot mounting hole 132. The silicone sleeve 161 is provided with a fixing groove 164 on the side facing the first cavity, and the weighing sensor 163 is disposed in the fixing groove 164. The scale body upper shell 12 is provided with an avoidance groove 121, which is used to avoid the weighing sensor 163, making the internal structure of the scale body 1 more compact and saving space.

[0054] The host 2 includes a host upper shell 22 and a host lower shell 23 . The host upper shell 22 and the host lower shell 23 are connected to form a second cavity. The wireless receiving module is disposed in the second cavity.

[0055] A second sealing member 24 is provided at the connection between the lower housing 23 and the upper housing 22. The lower housing 23 is provided with a second groove 231, and the second sealing member 24 is disposed in the second groove 231. When the upper housing 22 and the lower housing 23 are connected, the second sealing member 24 can achieve a sealing effect, preventing moisture and dust from entering the interior of the main unit 2 along the connection.

[0056] Furthermore, a second PCB board 25 is provided in the second cavity, and the control chip and the wireless receiving module are both soldered on the second PCB board 25 .

[0057] Specifically, the display screen includes a liquid crystal display screen 26 and a backlight panel 261 . The liquid crystal display screen 26 is electrically connected to the backlight panel 261 . The backlight panel 261 is electrically connected to the second PCB board 25 via a conductive adhesive strip 29 .

[0058] The scale body lower shell 13 and the main unit lower shell 23 are both provided with a battery compartment 4 and a battery cover 41. The battery compartment 4 contains a battery 40. The battery cover 41 can cover or open the battery compartment 4. A third seal 42 is provided at the connection between the battery cover 41 and the battery compartment 4. The third seal 42 can isolate the battery compartment 4 from the external environment, preventing moisture and dust from entering the battery compartment 4 and affecting the normal operation of the battery 40. The battery 40 located in the scale body lower shell 13 is electrically connected to the first PCB board 15 for powering the first PCB board 15; the battery 40 located in the main unit lower shell 23 is electrically connected to the second PCB board 25 for powering the second PCB board 25.

[0059] A physical switch 43 is provided on the side of both the scale body lower shell 13 and the main unit lower shell 23. The physical switch 43 is electrically connected to the battery 40. When the user is not using the electronic kitchen scale provided by this embodiment, the physical switch 43 can be used to completely cut off the power supply, preventing the battery 40 from being in standby mode for extended periods and thereby increasing the battery life of the battery 40. It should be noted that the principle of how the physical switch 43 cuts off the power supply is well understood by those skilled in the art and will not be elaborated upon here.

[0060] Furthermore, the outer periphery of the physical switch 43 is provided with a waterproof rubber sleeve 44, which is waterproof and moisture-proof, and protects the electronic components inside the scale body 1 from damage.

[0061] In this embodiment, the host 2 also includes a functional module, which includes a plurality of buttons 27 and a third PCB board 271. The third PCB board 271 is provided with contact switches 272 corresponding to the number of the buttons 27. The buttons 27 are mounted on the contact switches 272. The third PCB board 271 is electrically connected to the second PCB board 25. The contact switches 272 cooperate with the control chip to activate different functions of the host 2. The host upper shell 22 is provided with a plurality of button holes 221 corresponding to the contact switches 272. The buttons 27 extend along the button holes 221 to the outside of the host upper shell 22. The surface of the host upper shell 22 is provided with a glass panel 28 to protect the buttons 27 from dust and moisture, ensuring normal operation.

[0062] Common electronic scales on the market have a small number of buttons 27, and often a single button integrates multiple functions. Switching between functions requires long or short presses, which is cumbersome and unintuitive. The electronic kitchen scale provided in this embodiment, by providing multiple buttons 27 and a contact switch 272, can satisfy the requirement that each button 27 corresponds to a single function. The buttons 27 are labeled with corresponding function names, making operation easier and clearer.

[0063] Preferably, the display screen in this embodiment is provided with three display areas, which are respectively used to display time data, temperature data, and weight data. A button 27 for controlling the display area is provided next to each display area. In other words, the buttons 27 of the three display areas can be controlled and operated independently, and the display area can be turned on and off by the buttons 27 of the display area.

[0064] Example 2

[0065] The difference between this embodiment and the first embodiment is that the connection structure between the host 2 and the scale body 1 is that a lock 17 structure is used to replace the magnetic structure in the first embodiment.

[0066] Reference Figures 10 to 12In this embodiment, a protruding structure 212 is provided at one end of the main unit 2, and a locking buckle 17 is provided at one end of the scale body 1. The locking buckle 17 is adapted to the protruding structure 212. The main unit 2 and the scale body 1 can be connected by simply aligning the protruding structure 212 with the locking buckle 17 and manually pushing the protruding structure 212 to fit into the locking buckle 17. When the connection needs to be released, the protruding structure 212 can be disengaged from the locking buckle 17 by simply pushing the protruding structure 212 again in the direction of the locking buckle 17.

[0067] Preferably, the lock buckle 17 is connected to a first mounting seat 170 , and the protruding structure 212 is connected to a second mounting seat 213 .

[0068] Furthermore, the first mounting base 170 is provided with a first mounting hole 171, and the first mounting base 170 can be fixedly connected to the scale body 1 by engaging a screw with the first mounting hole 171. The second mounting base 213 is provided with a second mounting hole 2131, and the second mounting base 213 can be fixedly connected to the host 2 by engaging a screw with the second mounting hole 2131.

[0069] It should be noted that the lock buckle 17 and the protruding structure 212 are standard parts in the industry. Those skilled in the art should be aware of the cooperation principle between the two and can directly apply them.

[0070] It is understandable that those skilled in the art can, under the guidance of the above embodiments, combine various implementation methods in the above embodiments to obtain technical solutions of multiple implementation methods.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
