Waterproof and dampproof internet of things visual scale

Abstract

The invention relates to a waterproof and dampproof internet of things visual scale. The waterproof and dampproof internet of things visual scale comprises an electronic scale base, a support rod andan electronic scale instrument, wherein the electronic scale base is provided with a sensor module group for weighing; the support rod is arranged on one side of the electronic scale base; the electronic scale instrument is connected with the top end of the support rod and is provided with a control circuit; the sensor module group is arranged below the electronic scale base and is electrically connected with the control circuit; a sensor module in the sensor module group is arranged in a waterproof and dampproof seal housing; the surface of the waterproof and dampproof seal housing is in sealing connection with a waterproof and dampproof ventilation assembly for adjusting the difference of the pressure inside and outside a cavity; a support plate is used for connecting a sensor and the waterproof and dampproof seal housing to form a weighing sensor module group. Both the sensor module group and the electronic scale instrument in the electronic scale adopt a full-seal design, have waterproof, dampproof and ventilation properties, and can ensure the detection precision of the sensor module; and the electronic scale improves multiple functional modules.

Description

technical field [0001] The invention relates to the field of electronic scales, in particular to a waterproof and moisture-proof internet of things visual scale. Background technique [0002] Generally speaking, an electronic scale includes a sensor module and an electronic scale instrument. However, the sensor module of the existing electronic scale and the instrument of the electronic scale are not sufficiently sealed. If it is suitable for a humid environment or weighing objects with water, the sensor module and the meter head are easily damaged by water, which limits the scope of application of the electronic scale. . [0003] In addition, although some sensor modules adopt a sealed design, the sensor module is placed in a sealed casing, but because the temperature in the sealed casing will change with the ambient temperature, there will be an air pressure difference inside and outside the casing, which will affect the sensor module. detection accuracy, resulting in me...

AI Technical Summary

Problems solved by technology

In addition, since the sensor module of the electronic scale is placed on the ground, it is also easily damaged by mice, which shortens the overall service life of the electronic scale

[0004] At the same time, the shell of the existing electronic scale instrument is a plastic part, the strength is not enough, and it is easy to age, which affects the overall service life

In addition, the electronic scale instrument is usually installed on the support frame of the vertical electronic scale. When weighing, due to the different station conditions, the operator may sometimes be blocked by the electronic scale instrument and cannot clearly and directly see the weight on the electronic scale base. It is inconvenient for weighing objects

In addition, the control circuit of the electronic scale instrument also has some problems on the circuit module, for example: 1. The antenna is usually set outside the casing, which not only affects the appearance but is also easy to damage; 2. Usually only key switches or touch screens are provided. In the case of only setting the touch screen, if the touch screen fails, the operator cannot control the instrument; 3. The interface of the instrument is single, and the functions cannot be expanded

4. The unreasonable layout of the circuit modules cannot place a large number of batteries, resulting in low endurance of the instrument and the need for frequent charging
