Description

Technical Field

[0001] This utility model relates to a weighing instrument, and more particularly to a coffee scale. Background Technology

[0002] Existing coffee scales mainly consist of a weighing module, control circuit, display screen, and casing, and are widely used in coffee making scenarios requiring precise measurement, such as pour-over coffee and espresso. Because coffee brewing involves frequent contact with hot water and coffee liquid, and the operating environment is often humid, high demands are placed on the waterproof performance of the equipment. Currently, commercially available coffee scales, such as the one disclosed in patent document CN208125262U, typically use a silicone protective sleeve on the weighing pan. However, this simple structure protecting the surface of the weighing pan cannot prevent hot water or coffee liquid from seeping in through gaps in the casing. Over time, this can lead to circuit board corrosion, and such coffee scales still pose a risk of liquid leakage into the scale body, indicating a significant deficiency in overall protection. Utility Model Content

[0003] In order to improve the waterproof performance of existing coffee scales, this utility model provides a coffee scale with good waterproof performance.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A waterproof coffee scale includes a front shell and a bottom cover installed at the bottom of the front shell. A circuit board and a weighing sensor electrically connected to the circuit board are installed in the cavity formed by the front shell and the bottom cover. A human-machine interaction module and a retaining ring are provided on the front shell. A waterproof ring is installed in the closed space formed between the front shell and the retaining ring. A groove is provided on the bottom surface of the retaining ring to accommodate the waterproof ring. The inner side of the waterproof ring is deformed by a first extrusion wall on the top surface of the groove and a second extrusion wall on the side surface of the groove, while the outer side is pressed tightly by an upwardly protruding extrusion part of the front shell. The inner side of the waterproof ring is formed by the first extrusion wall on the top surface of the groove, the second extrusion wall on the side surface of the groove, and the upwardly protruding extrusion part of the front shell, which together constitute an orthogonal force decomposition structure.

[0006] The outer side of the baffle ring is configured as a vertical water-blocking surface, and the inner side is configured as an inwardly sloping surface; the bottom of the baffle ring extends into an insert post that is inserted into the face shell.

[0007] The edge of the human-computer interaction module is provided with a notch corresponding to the insertion post. During installation, the insertion post of the retaining ring passes through the notch of the human-computer interaction module and is inserted into the insertion hole of the face shell for fixation.

[0008] The top edge of the shell is provided with a spiral groove.

[0009] A water-receiving pad is installed on the top of the faceplate, and a protruding ring is provided at the bottom of the water-receiving pad, which is inserted into the U-shaped groove.

[0010] The edge of the water-receiving pad is provided with water-blocking protrusions, and the surface of the water-receiving pad is also provided with a water-receiving groove. A hand-held part extends from the side of the water-receiving pad for easy handling.

[0011] The side of the faceplate is provided with a toggle switch and a charging interface, and a sealing plug is also installed at the charging interface.

[0012] The beneficial effects of this utility model are as follows: A waterproof ring is installed in the closed space formed between the human-computer interaction module and the retaining ring, improving the waterproof performance of the coffee scale. An orthogonal force decomposition structure is also provided, which contacts the retaining ring and changes the direction of force on the waterproof ring. This orthogonal force decomposition structure changes the force on the waterproof ring, decomposing it into lateral and longitudinal components, preventing the retaining ring from expanding due to the elasticity of the waterproof ring. Furthermore, a water-receiving pad is installed on the faceplate, and a water-receiving groove is provided on the surface of the pad, capable of catching hot water or coffee liquid, preventing it from flowing down the faceplate surface and seeping into the assembly gaps of the coffee scale, further improving the waterproof performance of the coffee scale.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0023] Reference Figures 1 to 7 A waterproof coffee scale includes a face shell 1 and a bottom cover 2 installed at the bottom of the face shell 1. A circuit board and a weighing sensor electrically connected to the circuit board are installed within the cavity formed by the face shell 1 and the bottom cover 2. A human-machine interface module 3 and a retaining ring 4 are provided on the face shell 1. A waterproof ring 5 is installed in the enclosed space formed between the face shell 1 and the retaining ring 4. The bottom surface of the retaining ring 4 has a groove for accommodating the waterproof ring 5. The inner side of the waterproof ring 5 is deformed by a first extrusion wall 6 on the top surface of the groove and a second extrusion wall 7 on the side surface of the groove, while the outer side is pressed tightly by an upwardly protruding extrusion part 10 of the face shell 1. The inner side of the waterproof ring is deformed by the first extrusion wall 6 on the top surface of the groove and a second extrusion wall 7 on the side surface of the groove. The second extrusion wall on the side of the pressure groove and the extrusion part protruding upward on the surface of the shell together form an orthogonal force decomposition structure; the lower left corner of the waterproof ring 5 contacts the extrusion part 10 and deforms to the upper right corner, and the upper right corner contacts the first extrusion wall 6 and the second extrusion wall 7 and deforms to the lower left corner; this utility model installs a waterproof ring in the closed space formed between the human-computer interaction module and the retaining ring, and sets an orthogonal force decomposition structure that contacts the retaining ring and changes the force direction of the waterproof ring; a water-receiving pad is installed on the surface of the shell, and a water-receiving groove is set on the surface of the water-receiving pad, which can catch hot water or coffee liquid and other liquids, so that they will not flow down the surface of the shell and seep into the assembly gap of the coffee scale, further improving the waterproofness of the coffee scale.

[0024] like Figure 7 As shown, the pressure exerted by the extrusion section 10 on the lower left corner of the waterproof ring 5 is F1, and the pressure exerted by the first extrusion wall 6 on the top surface of the pressure groove and the second extrusion wall 7 on the pressure groove on the waterproof ring 5 is F2. In this embodiment, the force orthogonal decomposition structure decomposes F1 into two components: longitudinal F3 and transverse F4. Similarly, it decomposes F2 into two components: longitudinal F6 and transverse F5. By changing the force on the waterproof ring through the force orthogonal decomposition structure, it decomposes the force into transverse and longitudinal components, preventing the elastic effect of the waterproof ring from causing the retaining ring to expand. The waterproof ring isolates the liquid that seeps into the assembly gap, further improving the waterproof performance of the coffee scale.

[0025] In this embodiment, the human-computer interaction module adopts the control panel described in the patent document with publication number CN109141604A. Specifically, it consists of an LCD screen and touch buttons. The touch buttons include a power button and a peel button. Since the human-computer interaction module is a disclosed prior art solution, it will not be described in detail here.

[0026] The outer side of the baffle ring 4 is configured as a vertical water-blocking surface, and the inner side is configured as an inwardly sloping surface; the bottom of the baffle ring 4 extends into an insert post 40 that is inserted into the shell 1; when hot water or coffee liquid overflows, the vertical water-blocking surface of the baffle ring can block part of it. When the amount of overflowing water increases and exceeds the height of the water-blocking surface, the liquid will flow down the slope and will not accumulate in the gaps. By specifically configuring the baffle ring with the above-mentioned structure, the waterproof performance of the coffee scale can be further improved. Even if a large amount of liquid flows down from the coffee scale, it will not leak into the shell of the coffee scale.

[0027] The edge of the human-computer interaction module 3 is provided with a notch 30 corresponding to the insertion post 40. During installation, the insertion post 40 of the retaining ring 4 passes through the notch 30 of the human-computer interaction module 3 and is inserted into the insertion hole 11 of the face shell 1 for fixation.

[0028] The top edge of the faceplate 1 is provided with a spiral groove 12; a water-receiving pad 13 is installed on the top of the faceplate 1, and a convex ring 130 is provided at the bottom of the water-receiving pad 13, which is inserted into the spiral groove 12; the convex ring on the water-receiving pad is adapted to the spiral groove to prevent the water-receiving pad from moving with the weighed object, causing the center of gravity to shift and affecting the measurement accuracy.

[0029] The edge of the water-receiving pad 13 is provided with a water-blocking protrusion 131, and the surface of the water-receiving pad 13 is also provided with a water-receiving groove 133. A hand-held part 132 for easy picking up of the water-receiving pad 13 extends from the side of the water-receiving pad 13.

[0030] The side of the faceplate 1 is provided with a toggle switch and a charging interface, and a sealing plug 8 is also installed at the charging interface. In order to further improve the waterproof performance of the coffee scale, a sealing plug is also installed at the charging interface in this embodiment. The sealing plug is made of a material with a certain elasticity, such as silicone. The sealing plug is inserted into the charging interface to isolate the charging interface from the outside world and form a sealed cavity. The charging interface in this embodiment is specially selected as a TYPE-C interface, which has a symmetrical interface, does not require distinguishing between the right and wrong plugging, has a user-friendly plugging and unplugging experience, can effectively reduce the probability of interface damage, and is compatible with multiple fast charging protocols. The charging interface can also be replaced with a more conventional USB charging interface during production, and can be produced according to specific needs.
