Description

Technical Field

[0001] The embodiments of the present application relate to an electronic scale structure, in particular to a waterproof electronic scale. Background Art

[0002] An electronic scale is a weighing device that uses an electronic weighing sensor to weigh items and then converts the weight into an electronic reading that is displayed on a display screen. Electronic scales are divided into many types according to different usage scenarios. For example, when making coffee, it is necessary to quantitatively weigh and proportion various ingredients according to different types of coffee. Generally, a special coffee scale is used for such weighing operations.

[0003] The ingredients in the coffee preparation process are generally some powder or liquid materials such as coffee powder and milk. These materials often spill on the coffee scale, so the coffee scale needs to be cleaned frequently. In order to achieve a waterproof effect during the cleaning process and prevent moisture from penetrating into the scale body and affecting the electronic devices, the existing coffee scale is generally made into an integrated sealed structure, and the circuit board, display screen and weighing sensor are enclosed inside the integrated sealed scale body. However, this structure generally causes inaccurate weighing due to changes in air pressure. Therefore, it is necessary to set air holes on the scale body and add a breathable and waterproof membrane to balance the air pressure inside and outside the scale body, which increases material costs and assembly difficulty. Summary of the invention

[0004] An embodiment of the present application provides a waterproof electronic scale, which improves the weighing accuracy of the electronic scale while maintaining waterproofness by arranging a weighing sensor outside the scale body.

[0005] In order to achieve the above-mentioned purpose, a waterproof electronic scale of an embodiment of the present application includes a scale body, a weighing sensor and a weighing pan, and the improvement lies in that the scale body is an integrated sealing structure, a weighing sensor installation position is provided on the scale body, and the weighing sensor is installed at the bottom of the weighing pan and then arranged in the weighing sensor installation position.

[0006] Since the waterproof electronic scale of this embodiment uses the scale body as an integrated structure, and places the weighing sensor and the weighing pan outside the integrated structure, the weighing sensor and the weighing pan can be removed for cleaning and the scale body can be cleaned with water. When a waterproof weighing sensor is used, it can be cleaned directly without disassembly. When in use, the weighing sensor is connected to the external space of the scale body and is not affected by changes in air pressure on the weighing accuracy, thereby improving the use accuracy and stability of the electronic scale.

[0007] In a possible implementation, the weighing sensor installation position is a groove provided in the middle of the scale body. The weighing sensor is installed in the groove, which can effectively reduce the stacking height of the components and is more conducive to the lightness and portability of the product.

[0008] In a possible implementation, the weighing pan includes a connecting pan for connecting and installing with a weighing sensor, an intermediate pan covering the connecting pan, and a weighing panel covering the intermediate pan.

[0009] In a possible implementation, the connection disk is a horizontal plate-shaped structure, and a mounting surface is provided on the connection disk at a location corresponding to the connection of the weighing sensor, which is partially recessed downward, and the bottom surface of the mounting surface is in contact with the weighing sensor.

[0010] In a possible implementation, the edge contour of the intermediate disk is adapted to the edge contour of the connecting disk, a downwardly bent curling edge is provided at the edge of the intermediate disk, and the intermediate disk is buckled onto the connecting disk via the curling edge.

[0011] In a possible implementation manner, the edges of the weighing panel have an edge-wrapping structure extending downward to wrap around the edges of the middle plate and the connecting plate.

[0012] In a possible implementation, water guide grooves are provided on the surfaces of the weighing panels on both sides of the weighing panel.

[0013] In a possible implementation, the weighing panel is a tray structure with two sides extending outward from the edges of the scale body, the edges of the tray are provided with upwardly folded edges, and the bottom of the tray is provided with positioning strips that cooperate with the edges of the middle plate on both sides.

[0014] In one possible implementation, the scale body has a main shell located below the scale pan and a control area shell located on one side of the main shell.

[0025] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail by way of implementation methods with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0026] It should be noted that: in the accompanying drawings, the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions; in the description of the present application, the terms "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; in the description of the present application, "first", "second", etc. are only used to distinguish each other, rather than to indicate their importance and order, etc.

[0027] The main purpose of this application is to realize a waterproof electronic scale structure in which the scale body of the electronic scale is designed as a closed structure, and the weighing sensor is placed outside the closed structure scale body to avoid the pressure change from causing an adverse effect on the weighing accuracy of the weighing sensor in the closed space. Figure 1 As shown, the waterproof electronic scale in the embodiment of the present application includes a scale body 1, a weighing sensor 2 and a weighing pan 3. The scale body 1 is an integrated sealing structure. A weighing sensor installation position 11 is provided on the scale body 1. The weighing sensor 2 is fixed to the bottom of the weighing pan 3 and then installed in the weighing sensor installation position 11.

[0028] As for electronic scales, the scale body generally includes a built-in battery or battery compartment, a display screen for setting or reading, control buttons, and a circuit board, that is, a power cord connecting various electronic components. Therefore, a sealed scale body is needed to seal the above-mentioned components therein to achieve the effect of isolating external moisture. The scale body is generally composed of an upper and lower shell body, forming a hollow space inside which accommodates the above-mentioned components. The sealing of the scale body can be achieved at the joints of the shell or the connections of the fasteners through additional waterproof measures such as waterproof glue and sealing gaskets, or the shell can be processed in an integrated manner by ultrasonic welding or other processing methods. After constructing the scale body with an integrated sealed structure, only one wire connected to the weighing sensor needs to be reserved, and the wiring point is also sealed with waterproof glue.

[0029] After adopting the above structural scheme, the weighing sensor and the weighing pan are placed outside the integrated sealing structure. When cleaning, the weighing sensor and the weighing pan are removed and the scale body can be cleaned with water, which is convenient for cleaning and can prevent water from flowing into the inside of the scale body and affecting the electronic devices. At the same time, when in use, the weighing sensor is connected to the external environment, so it is not affected by changes in air pressure on the weighing accuracy, thereby ensuring the weighing accuracy and use stability of the electronic scale.

[0030] As for the weighing sensor, if a weighing sensor with waterproof performance is used, since the weighing sensor is the only exposed electronic component in this embodiment, when the weighing sensor is a waterproof weighing sensor and the wiring joints are waterproofed, when cleaning, the scale pan and the weighing sensor do not need to be removed and can be cleaned directly.

[0031] In this embodiment, during installation, the weighing sensor 2 is first installed and fixed in the weighing sensor installation position 11, and then the scale plate 3 is fixed to the weighing sensor 2 to complete the structural assembly of the entire electronic scale. Therefore, the weighing sensor 11 is located on the scale body 1 and has a structure for fixing the weighing sensor. The fixing position and the weighing sensor 2 can be fixed by fasteners, snap-fitting, and other fixing methods. The specific structural form of the weighing sensor installation position 11 can be selected according to the shape and space conditions of the actual electronic scale. Figure 2 As shown, in one embodiment, the weighing sensor installation position 11 is a groove provided in the middle of the scale body. During installation, the weighing sensor 2 is fixed in the groove, which can effectively reduce the stacking height of the components, making the product thin and portable. At the same time, it can also reduce the gap between the scale body and the scale pan, preventing the water carried by the weighed object from flowing into the groove during the weighing process.

[0032] When disassembly and cleaning are required, the weighing pan 3 can be removed from the weighing sensor 2 first, and then the weighing sensor 2 can be removed from the weighing body 1, and the weighing body 1 can be cleaned separately.

[0033] In the specific structure of the scale pan, such as Figure 3 As shown, in one embodiment, the weighing pan 3 includes a connection pan 31 for connecting and fixing with a weighing sensor, an intermediate pan 32 covering the connection pan, and a weighing panel 33 covering the intermediate pan. The connection pan 31 is mainly used for connecting and fixing with the weighing sensor 2 and as an integral support for the weighing pan 3. The intermediate pan 32 is located in the middle layer of the weighing pan 3 and is mainly used to keep the weighing pan with a complete and hard supporting plane. The weighing panel 33 is located in the uppermost layer of the weighing pan 3 and is used to directly contact the object to be weighed. The weighing panel 33 can be a flexible and removable structure. The main purpose of the removable structure is to be removable and cleaned separately during cleaning. The main purpose of the flexible structure is that it can be cleaned in the same way as for flexible materials after disassembly. For example, when a silicone material is used, it can be cleaned in any way such as rubbing, scrubbing, and drying.

[0034] Since the connecting plate 31 is mainly used for connecting and fixing with the weighing sensor 2 and serving as the overall support of the weighing plate 3, and the weighing sensor 2 is located in the groove of the scale body 1, the weighing sensor 2 has a relatively low horizontal height, in order to make the connecting plate 31 and the weighing sensor be well fixed, such as Figure 4 As shown, in one embodiment, a mounting surface 311 partially recessed downward is provided at the connection position corresponding to the weighing sensor 2 on the connecting disk 31, and the bottom surface of the mounting surface 311 is in contact with the weighing sensor 2. When the connecting disk 31 is a metal disk, the mounting surface 311 can be formed by stamping. At the same time, in order to facilitate the removal and placement of the mounting disk, two holes 312 can be symmetrically stamped in the middle of the connecting disk to form an action portion 313 that is easy to operate manually. By pinching the action portion 313, the connecting disk 31 can be operated to move, and the mounting surface 311 can be aligned with the installation position of the sensor, and then fixed by fasteners.

[0035] Regarding the structure of the middle disk, such as Figure 5 As shown, in one embodiment, the edge profile of the intermediate disk 32 is adapted to the edge profile of the connecting disk 31, and a downwardly bent curling edge 321 is provided at the edge of the intermediate disk 32, and the intermediate disk 32 is buckled on the connecting disk 31 through the edge folding edge 321. The buckling matching structure can effectively prevent the intermediate disk 32 from being displaced in the horizontal direction, maintain the stability of the scale plate part during weighing, and also when disassembling and installing the scale plate, there is no need to use additional fasteners to fix the connecting disk 31 and the intermediate disk 32.

[0036] In the above embodiments, the weighing panel 33 is located at the top layer of the scale pan 3, contacts the object to be weighed, and is also the component most likely to contact with water or frequently need to be cleaned. In order to take into account the waterproof effect, two embodiments are proposed below to illustrate its structure.

[0037] like Figure 6 As shown, in one embodiment, the edges of the weighing panel 33 are provided with a wrapping structure 331 extending downward to wrap around the edges of the middle plate and the connecting plate. The weighing panel 33 with this structure is particularly suitable for the material of the flexible weighing panel in the above content, such as a silicone panel. The wrapping structure 331 around the edges forms a closed state for the entire side of the weighing pan 3, thereby preventing water from flowing into the layers of the weighing pan 3 and affecting the weighing accuracy.

[0038] Based on the weighing panel 33 of the above structure, water guide grooves 332 are provided on the weighing panel surface on both sides of the weighing panel 33. Both sides of the water guide grooves 332 are in a conductive state. When cleaning, the water left on the weighing panel 33 can be drained through the water guide grooves 332 by tilting the weighing panel 33, thereby improving the weighing accuracy. At the same time, the provision of the water guide grooves 332 also makes the surface of the weighing panel 33 have an anti-slip structure and effect.

[0039] like Figure 7 As shown, in one embodiment, a structural form suitable for a hard weighing panel is also proposed, wherein the weighing panel 33' is a tray structure with two sides extending outward from the edges of the two sides of the scale body, the edge of the tray is provided with an upwardly folded edge 333, and the bottom of the tray is provided with a positioning strip 334 that cooperates with the edges of the two sides of the middle plate.

[0040] In terms of the structure of the scale, Figure 8 As shown, in one embodiment, the scale body 1 has a main housing 12 located below the scale pan and a control area housing 13 located on one side of the main housing. The main housing 12 and the control area 13 housing are an integrated closed structure, and the width of both sides of the main housing 12 and the upper surface height are smaller than the width of both sides of the control area housing 13 and the control area surface height. Since the main housing 12 is the area of ​​the scale body 1 located below the scale pan 3, the width and height of the main housing 12 are appropriately retracted inward, so that the scale pan 3 can completely cover the main housing 12, and even if there is overflow water on the scale pan 3 and flows down to the surroundings, it will naturally drip into the space around the scale body.

[0041] In the above embodiments, since they are all about the structure of electronic scales, electronic scales generally need to be charged for use, so they have a charging structure, or some electronic scales can derive output, so there are charging and data transmission interfaces. In order to waterproof the interfaces, such as Fig. 9 As shown, a wiring port 14 is provided on the side of the scale body 1 , and the wiring port 14 is closed by a cover 15 .

[0042] The above description is only a preferred embodiment and does not limit the patent scope of this application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of this application.
