Description

[Technical Field]

[0001] This utility model relates to a dustproof knob for electronic scales. [Background Technology]

[0002] In existing kitchen scales, especially those with knobs, there is a large gap between the knob and the scale panel. During use, the scale is easily exposed to dust, which enters the scale body through this gap and combines with moisture in the air to form a paste. This affects the heat dissipation of the internal electronic modules and the gear meshing function. In some cases, the accumulated paste-like dust in the gap between the knob and the side of the scale panel can prevent the knob from turning, thus affecting the scale's functionality.

[0023] Figure 4 This is a cross-sectional view of the knob and decorative cover of this utility model. [Detailed Implementation]

[0024] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0026] like Figure 1-4 As shown, an electronic scale dustproof knob includes a scale body 1 and a knob 2. The upper side of the scale body 1 has a scale body through hole 11 for the lower end of the knob 2 to be inserted. A surrounding rib 3 extending upwards around the scale body through hole 11 is provided on the upper side of the scale body 1. The outer side of the knob 2 has a knob cap 21 extending outwards around it. The lower side of the knob cap 21 has a first groove 22 that surrounds it and cooperates with the surrounding rib 3. In this embodiment, the gap between the lower side of the knob cap 21 and the upper side of the scale body 1 is very small. The first groove 22, in cooperation with the surrounding rib 3, prevents dust from entering the scale body through the scale body through hole 11. Simultaneously, the knob cap 21 on the outer side of the knob 2 further blocks the scale body through hole 11, and the small gap between the lower side of the knob cap 21 and the upper side of the scale body 1 also reduces dust entry.

[0027] like Figure 1-4 As shown, a mounting cover plate 4 is provided on the through hole 11 of the scale body. The mounting cover plate 4 is provided with a cover plate through hole 41 for the lower end of the knob 2 to be inserted. The surrounding rib 3 is provided on the upper side of the mounting cover plate 4 and surrounds the cover plate through hole 41. The mounting cover plate 4 is provided to facilitate the assembly of the knob 2 and other components of the electronic scale, and also to facilitate the setting of the surrounding rib 3.

[0028] like Figure 1-4 As shown, the upper side of the knob cap 21 has a cap rim slope 23 that gradually slopes downward from the inside out, and the upper side edge of the mounting cover plate 4 has a chamfered rounded edge 42. The cooperation between the cap rim slope 23 and the chamfered rounded edge 42 can reduce the accumulation of dust in the knob 2, and can drive the accumulated dust away from the knob 2 when the knob 2 is rotated, thus reducing the gap between the knob 2 and the mounting cover plate 4.

[0029] like Figure 1-4 As shown, the lower side of the knob cap 21 is provided with a second groove 24 surrounding the cap, and the first groove 22 is located at the bottom of the second groove 24. The distance D1 between the reinforcing rib 3 and the edge of the mounting cover plate 4 is greater than the distance D2 between the outer side of the second groove 24 and the outer edge of the first groove 22, so that dust entering from the small gap between the lower side of the knob cap 21 and the upper side of the scale body 1 will not immediately accumulate in the small gap and cause blockage, but can be collected by the second groove 24 for easy cleaning later.

[0030] like Figure 1-4 As shown, a connecting protrusion 5 is provided on the inner bottom surface of the scale body 1, located inside the scale body through hole 11. The knob 2 has a knob lower groove 25 with an opening at the lower end for the connecting protrusion 5 to extend into. The top of the connecting protrusion 5 is detachably and rotatably connected to the upper side of the knob 2. The knob 2 is rotatably connected to the connecting protrusion 5, so that the knob 2 and the mounting cover plate 4 are set in the scale body through hole 11, and the knob 2 can rotate relative to the mounting cover plate 4 and the scale body 1.

[0031] like Figure 1-4 As shown, the upper side of the knob 2 is provided with an end cap 6, and the upper side of the knob 2 is provided with a first groove 26 on the upper side of the knob for the end cap 6 to be inserted. The end cap 6 can cover the connector between the knob 2 and the connecting protrusion 5. In this case, the connector is a screw, which improves the overall aesthetics of the knob 2.

[0032] like Figure 1-4 As shown, the upper side of the knob has a first groove 26 with a second groove 27. The bottom surface of the second groove 27 has a knob groove through hole 28. The top of the connecting protrusion 5 has a protrusion boss 51 that fits into the knob groove through hole 28. The top surface of the protrusion boss 51 has a screw 7 that allows the knob 2 to be rotatably connected to the connecting protrusion 5. The screw 7 fixes the knob 2 on the connecting protrusion 5 and allows it to rotate around the connecting protrusion 5. This also makes it easy to install and remove the knob 2 to clean dust.

[0033] like Figure 1-4 As shown, the upper part of the outer side of the knob 2 is provided with anti-slip texture 29, which makes it easy to rotate the knob and easy to grasp the knob so that the knob can be separated from the mounting cover.

[0034] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
