According to the utility model, the electronic balance is arranged in the protective cover, and the humidity inside the shell is detected in real time through the humidity sensor. Wherein, the blast pipe is connected with the atmosphere, and the intake pipe is connected with a dry air source. When detecting humidity too big, then make the inside humidity of casing decline through opening the admission valve, let in dry air, after letting in dry air, internal pressure increases, at this moment, inside gas slowly discharges along the blast pipe, waits for humidity transducer's reading after normal, closes the admission valve, waits for a period of time, until inside gas is the same with atmospheric pressure, uses again to guarantee the accuracy of weighing.

Description

Electronic balance protection cover

Technical Field

The utility model relates to the technical field of protective covers, in particular to an electronic balance protective cover.

Background

The electronic balance is used for weighing the mass of an object and is characterized by being accurate and reliable in weighing, rapid and clear in display and provided with an automatic detection system. Electronic balances are a precision instrument and therefore require careful maintenance. The existing protective cover of the electronic balance is only a simple cover body, has no drying function, and can influence the accuracy of weighing substances of the electronic balance after the balance is wetted.

Disclosure of Invention

In order to solve the technical problems, the utility model discloses an electronic balance protection cover, and the technical scheme of the utility model is implemented as follows:

An electronic balance protective cover comprises a shell, a fixed plate, a humidity sensor, an exhaust pipe, an air inlet pipe and an air inlet valve;

The fixed plate is arranged at the bottom of the shell, the humidity sensor is connected with the shell, the exhaust pipe is connected with the air inlet pipe, the air inlet valve is arranged on the air inlet pipe.

Preferably, the fixing plate is hollow. The inside of the fixed plate is filled with a drying agent.

Preferably, the upper surface of the fixing plate is provided with anti-skid patterns.

Preferably, the fixing plate is detachably connected with the bottom of the housing.

Preferably, the fixing plate is made of soft foaming material.

According to the utility model, the electronic balance is arranged in the protective cover, and the humidity inside the shell is detected in real time through the humidity sensor. Wherein, the blast pipe is connected with the atmosphere, and the intake pipe is connected with a dry air source. When detecting humidity too big, then make the inside humidity of casing decline through opening the admission valve, let in dry air, after letting in dry air, internal pressure increases, at this moment, inside gas slowly discharges along the blast pipe, waits for humidity transducer's reading after normal, closes the admission valve, waits for a period of time, until inside gas is the same with atmospheric pressure, uses again to guarantee the accuracy of weighing.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples

In a specific embodiment, as shown in fig. 1, an electronic balance protection cover comprises a shell 2, a fixing plate 3, a humidity sensor 4, an exhaust pipe 5, an air inlet pipe 6 and an air inlet valve 7; wherein, fixed plate 3 sets up in casing 2 bottom, and humidity transducer 4 connects casing 2, and casing 2 is connected to blast pipe 5 and intake pipe 6, and intake valve 7 sets up on intake pipe 6.

In this embodiment, the electronic balance 1 is disposed on the fixing plate 3 in the housing 2, the humidity sensor 4 detects the humidity in the housing 2 in real time, the exhaust pipe 5 is connected to the atmosphere, and the air inlet pipe 6 is connected to a dry air source. When humidity sensor 4 detects that humidity is too big, then let in dry air through opening admission valve 7 and make the inside humidity of casing 2 drop, after letting in dry air, the inside gas temperature of casing 2 and pressure rise, inside gas just slowly discharges along blast pipe 5, wait that humidity sensor 4's reading is normal back, close admission valve 7, wait for a period of time, until inside gas is the same with atmospheric pressure, use again, in this way, just can guarantee humidity and the pressure constancy when weighing of electronic balance 1, and then guarantee the accuracy of weighing.

In a preferred embodiment, the fixing plate 3 is hollow. The inside of the fixing plate 3 is filled with a desiccant.

In this embodiment, the desiccant is inserted into the fixing plate 3, so that the humidity in the housing 2 is further ensured to be reduced, and the accuracy of weighing is further improved.

In a preferred embodiment, the upper surface of the fixing plate 3 is provided with anti-slip patterns.

The purpose of the anti-skid is to increase the friction between the electronic balance 1 and the fixed plate 3, thereby ensuring the stability of the electronic balance 1.

In a preferred embodiment, the fixing plate 3 is detachably connected to the bottom of the housing 2.

The detachable connection mode ensures that the drying agent can be conveniently replaced after failure so as not to influence the accuracy of subsequent weighing.

In a preferred embodiment, the fixing plate 3 is made of a soft foam material.

The soft foam material has a certain degree of buffering capacity, and can reduce the shock to which the electronic balance 1 is subjected to a certain degree.

It should be noted that the above-mentioned embodiments are only preferred embodiments of the present utility model, and are not intended to limit the present utility model, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
