Description

Technical Field

[0001] The invention relates to the field of kitchen supplies, in particular to a chopping board scale. Background Art

[0002] With the development of the economy, people's living standards are improving day by day, and people pay more and more attention to the nutritional combination of their daily diet. In daily cooking, it is often necessary to accurately match the weight ratio of various ingredients so that the taste of the dishes can be best presented and have a balanced nutritional combination. In the past, kitchen scales were used to accurately control the weight ratio of ingredients, but most ingredients needed to be processed on the chopping board before they could be weighed and cooked. Moving ingredients back and forth between the scale and the chopping board would cause waste of ingredients and delay time, which is not suitable for the current fast pace of life. The chopping board scales currently available on the market are simply a simple combination of a scale and a chopping board. Using this chopping board scale for high-impact operations such as chopping bones will cause damage to the internal weight sensor and a short service life. Summary of the invention

[0003] The object of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a cutting board scale which can protect a weight sensor from being damaged by the impact of operations such as cutting and chopping, thereby extending the service life.

[0004] According to a first aspect of the present invention, there is provided a chopping block scale, comprising: a base, a panel, and a weight sensor and an overweight protection component arranged between the panel and the base, wherein a force perpendicular to the upper surface of the panel can be transmitted to the weight sensor, and when the weight sensor reaches a maximum range, the overweight protection component limits further deformation of the weight sensor.

[0005] The chopping block scale provided according to the technical solution of the present invention has the following beneficial effects: the weight sensor can give the chopping block scale a weighing function, which can reduce the food handling process and thus improve cooking efficiency, and reduce waste caused by the handling process. The weight sensor mainly relies on its elastic structure to deform when it bears weight to convert mass into an electrical signal output. When the sensor is subjected to excessive impact force, the deformation of the elastic structure may exceed its elastic limit and cannot or cannot completely restore the deformation, and the sensor will be damaged. The overweight protection component can play the role of supporting and sharing the impact force and suppressing the sensor from exceeding its maximum deformation degree when performing operations with large impact force such as chopping or cutting, thereby protecting the weight sensor from being damaged.

[0006] Furthermore, one end of the overweight protection component is fixed on the panel, and a gap is set between the other end of the overweight protection component and the base; or one end of the overweight protection component is fixed on the base, and a gap is set between the other end of the overweight protection component and the panel, and when the weight sensor reaches the maximum range, the gap value is 0. This is a specific implementation of the overweight protection component, which is suitable for various weight sensors. When the weight sensor reaches the maximum range, the overweight protection component supports the panel and the base to share the impact force, which inhibits further deformation of the weight sensor and protects the weight sensor.

[0007] Furthermore, the weight sensor is a beam-type weight sensor made of aluminum material, the weight sensor is horizontally placed between the panel and the base, the first fixed end of the weight sensor is mechanically connected to the panel, and the other second fixed end of the weight sensor is mechanically connected to the base. Aluminum profiles have high toughness, strong elasticity, and are not easy to damage. The beam-type weight sensor is a type of single-point weight sensor with a small size and is commonly used in thinner weighing equipment such as flat scales. This sensor drives the deformation of the strain resistor attached to the surface of the beam body through the deformation of the parallel beam, causing the resistance value to change and converting the weight into an electrical signal output.

[0008] Furthermore, one end of the overweight protection component is fixed on the panel, and a gap is provided between the other end of the overweight protection component and the second fixed end of the weight sensor; or one end of the overweight protection component is fixed on the base, and a gap is provided between the other end of the overweight protection component and the first fixed end of the weight sensor, and when the weight sensor reaches the maximum range, the gap value is 0. This is another embodiment of the overweight protection component, which is only applicable to the installation method of the beam-type weight sensor. When the weight sensor reaches the maximum range, the gap value is 0, and the overweight protection component and one end of the weight sensor jointly support the panel and the base, share the impact force, and limit the further deformation of the weight sensor to protect the weight sensor.

[0009] Furthermore, the panel includes a surface shell and a force-bearing plate, the force-bearing plate is detachably mounted on the surface shell, and one end of the overweight protection component is fixed to the surface shell. The force-bearing plate is used to hold and process food, and is detachable for easy cleaning and replacement when damaged.

[0010] Furthermore, the weight sensor is connected to the panel via a bracket, and the weight sensor is connected to the base via the scale feet. The bracket and the scale feet provide space required for the deformation of the beam-type weight sensor, and can also absorb part of the impact force.

[0011] Furthermore, the bracket and the scale foot are both single-layer step-shaped structures, the first surface of the bracket is connected to the panel, the second surface of the bracket is connected to one end of the weight sensor, the first surface of the scale foot is connected to the other end of the weight sensor, and the second surface of the scale foot is connected to the base. The step structure has a certain elasticity and can absorb part of the impact force.

[0012] Furthermore, there are two weight sensors, which are arranged in parallel between the panel and the base, and the overweight protection component is connected to the panel. The number of the overweight protection components is not less than the number of the weight sensors, and the overweight protection component is made of rigid material. The face shell can be supported more stably, so that the weighing result is more accurate and stable, and each weight sensor can be protected at the same time. Rigidity can provide better support and better protect the sensor.

[0013] Furthermore, the base includes a bottom shell and a buffer bracket, and the bottom shell surrounds the side of the buffer bracket. The buffer bracket can absorb vibration and noise, reduce the noise generated when using the cutting board scale for cutting or chopping, and improve the user experience.

[0014] Furthermore, it also includes a control module disposed between the panel and the base and a control panel disposed on the panel, the control module is electrically connected to the weight sensor, the control module has a timing function, a plurality of buttons and a digital display screen are disposed on the control panel, the buttons and the digital display screen are electrically connected to the control module, and a corrosion-resistant sealing ring is disposed at the connection between the panel and the base. It is often necessary to control the time during cooking, which further improves the user experience of the chopping block scale. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Reference Figure 1 to Figure 4According to an embodiment of the present invention, a cutting board scale comprises a panel, a base, a weight sensor 30 and an overweight protection component 11 arranged between the panel and the base. The panel and the base are assembled up and down to form a space for accommodating the internal mechanism of the cutting board scale. The panel comprises a face shell 10 and a force plate 14 detachably mounted on the face shell 10. The force plate 14 is a place for processing food materials and can be made of materials commonly used in ordinary cutting board scales, such as bamboo, solid wood board or plastic. In this embodiment, the weight sensor 30 is connected to the face shell 10 through a bracket and connected to the buffer bracket 21 through a scale foot 31, so as to play a certain supporting role. At the same time, the weight sensor 30 can also convert its shape change when it bears weight into an electrical signal, and convert the electrical signal into the mass of the food materials carried on the panel 10. The overweight protection component 11 is used to limit the deformation of the weight sensor part exceeding its range when cutting, chopping, patting and other actions with large impact are performed on the cutting board scale, so as to protect the weight sensor 30 from being damaged by the impact.

[0032] In the present embodiment, the overweight protection component 11 is connected to one of the panel or the base. When it is connected to the panel, there is a certain gap between it and the base; conversely, when it is connected to the base, there is a certain gap between it and the panel. The size of the gap needs to be selected according to the range of the weight sensor 30. When the weight sensor 30 reaches the maximum range, its deformation is also the largest. At this time, the overweight protection component 11 is in contact with both the panel and the base, playing a supporting role, and can prevent the weight sensor 30 from further deformation and damage. Therefore, preferably, the overweight protection component 11 should be made of rigid material, such as steel, iron or relatively hard ceramics or rubber. In the present embodiment, the overweight protection component 11 is connected to the face shell 10.

[0033] In this embodiment, preferably, the weight sensor 30 is preferably a beam-type weight sensor, which is a type of single-point weight sensor. This type of sensor is in the shape of a long strip, and the middle of the sensor is hollowed out to form a pair of parallel beam structures. The sensor is provided with a resistance strain gauge whose resistance value changes with deformation, and is often used in thin weighing equipment such as a platform scale. When in use, the sensor is placed horizontally between two platforms, and the two ends are fixed ends connected to the platform for carrying objects and the supporting platform respectively, and the middle part is suspended to leave space for the sensor to deform. In this embodiment, one end of the weight sensor 30 is connected to the scale foot 31, and the other end is connected to the face shell 10 through the bracket 31. The scale foot 31 and the bracket 32 ​​are both step-shaped structures. The upper surface of the upper table of the bracket 32 ​​is connected to the face shell 10, and the lower surface of the lower table is connected to one end of the weight sensor 30. The other end of the weight sensor 30 is connected to the upper surface of the upper table of the scale foot 31, and the lower surface of the lower table of the scale foot 31 is connected to the base through the buffer bracket 21. The bottom shell 20 surrounds the side of the buffer bracket 21 to form a base, and the buffer bracket 21 contacts the kitchen countertop. In this embodiment, the scale foot 31 and the bracket 32 ​​are made of metal. It is understandable that the scale foot 31 and the bracket 32 ​​can also be made of other tough materials such as plastic or rubber with high strength. The scale foot 31 and the bracket 32 ​​can not only transmit force so that the weight sensor can work normally, but also have a certain elasticity and can absorb a certain impact force. It should be understood that the gravity sensor 30 can also be directly connected to the panel and the base. It only needs to set a boss on the lower surface of the panel and the base, and connect the two fixed ends of the weight sensor 30 to the boss of the panel and the base respectively. Preferably, the weight sensor 40 is made of aluminum material with good toughness and is not easy to be damaged. In this embodiment, preferably, the chopping block scale has two weight sensors 40, which are parallel and symmetrically arranged in the chopping block scale. The arrangement of the above-mentioned weight sensors 40 can support the face shell more stably, make the force of the weight sensor 40 more uniform, and the measurement result more accurate. In this embodiment, the overweight protection component 11 is a metal cylinder, which is arranged on the side of one end where the weight sensor 40 is connected to the surface shell 10. When the cutting board scale is subjected to force, the deformation amount of the weight sensor 40 at this point is the largest, and the protection effect of the overweight protection component 11 is the best.

[0034] When the weight sensor 30 is a beam-type weight sensor, there is another way to set the overweight protection component 11. Figure 5-6 . Figure 5 for Figure 6The installation diagram of the weight sensor 30 and the overweight protection component 11 on the left side of the middle. In this embodiment, the fixed end of the weight sensor 30 located at the front end is connected to the face shell 10 through the bracket 32, and a deformation gap is left between the weight sensor 30 and the scale foot 31; the fixed end of the weight sensor 30 located at the rear end is connected to the buffer bracket 21 through the scale foot 31, and a deformation gap is left between the bracket 32. In this embodiment, the overweight protection component 11 is arranged between the bracket 21 and the fixed end of the rear end of the weight sensor 30. When the weight sensor 30 reaches the maximum range, the overweight protection component 11 contacts the fixed end of the sensor, jointly supports the panel and the base, shares the impact force, and hinders the weight sensor 30 from further deformation, so as to protect the weight sensor 30 from being damaged by excessive impact force. It can be understood that the overweight protection component 11 can also be arranged in the gap between the fixed end of the weight sensor 30 and the scale foot 31. In this embodiment, the overweight protection component 11 is a cylindrical boss arranged on the bracket 32. It can be understood that the overweight protection component 11 can also be other structures that can achieve stable support, and the overweight protection component 11 can also be an integrated structure with the scale foot 31 or the bracket 32.

[0035] In this embodiment, a control panel is provided at the front end of the surface shell 10. The control panel includes a digital display screen 12 and a plurality of buttons 13. The digital display screen can display the weight value and unit, and can also display the timing time. The button 13 can realize the input of various commands such as switching working modes, setting parameters, switching units, and turning on and off the machine. A control module is provided inside the shell. The control module is electrically connected to the weight sensor 40, the digital-analog display screen 12 and the button 13. The control module converts the electrical signal of the weight sensor 40 into a weight value under the corresponding unit, and displays it through the digital display screen 12. It can also receive instructions issued by the button 13 and perform corresponding actions. In addition, the control module also has a timing function, which is convenient for controlling various times during cooking.

[0036] In the present embodiment, a corrosion-resistant sealing ring is provided at the joint between the surface shell 10 and the bottom shell 20. The digital display screen 12 and the button 13 are also waterproof, and a corrosion-resistant sealing sleeve is provided on their surface. The above scheme enables the chopping board scale to be waterproof, and can be rinsed with running water, which is convenient for use, and can also prevent the juice of the food from damaging the internal components of the chopping board scale. In the present embodiment, the connection between the shell, the weight sensor 40, the scale foot 41, the bracket 42 and the plastic 21 is threaded. The force plate 14 and the surface shell 10 are detachably connected by a pull-out slide structure.

[0037] Reference Figure 7, is a control principle diagram of an embodiment of the present invention. Among them, U1 is a weight sensor 40, LCD is a digital display screen 12, SW1~SW6 are a plurality of buttons 13, and U2 is a control chip of a control module. The pins of the control chip U2 are respectively connected to the weight sensor U1, the digital display screen LCD and the buttons SW1~SW6. The control chip U2 converts the electrical signal of the weight sensor U1 into a weight value of the corresponding unit and outputs it to the digital display screen LCD for display. In this embodiment, the chopping block scale supports weight display in four units: ounces, grams, milliliters and pounds. In this embodiment, there are six function buttons, namely TIMR, MIN, SEC, STAR / STOP, ON / ZERO and UNIT / HOLD. The TIMR key is used to switch the timing state and the weighing state, MIN is used to set the minute value in the timing state, SEC is used to set the time value in the timing state, STAR / STOP is used to start and pause the timing, ON / ZERO is used to turn on and off the machine and read and reset the timing time, and UNIT / HOLD is used to switch the unit and hold the weighing reading.

[0038] The chopping block scale according to the embodiment of the present invention can complete the weighing work while processing the ingredients, saving cooking time and reducing the waste caused by carrying the ingredients. At the same time, an overweight protection component is provided inside the chopping block scale to share the impact force and suppress the over-range deformation of the weight sensor. Conventional high-impact actions such as cutting and chopping can be performed directly on the chopping block scale without damaging the weight sensor. At the same time, the chopping block scale also has a timing function, which is convenient for controlling various times during the cooking process and can enhance the user experience.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
