Description

A kind of electronic scale that waterproof insectproof effect is good

Technical field

The utility model belongs to weighing apparatus, and in particular to a kind of electronic scale that waterproof insectproof effect is good.

Background technique

Electronic scale is the tool for being weighed, being valuated to kinds of goods.Electronic scale include scale base, for carry need to weigh Kinds of goods the scale pan, scale base includes pedestal and lid, and cover cap is constituted on pedestal for accommodating gravity sensitive device assembly and its The accommodation space of its electric elements (such as wiring board), the bottom of the scale pan are equipped with connecting column, open up on lid and pass through for connecting column Relief hole, the scale pan is located on scale base and connect with gravity sensitive device assembly by connecting column.The electronic scale of this structure is in reality Existing defects when border uses: electronic scale use environment is complex, and external water, worm, sundries etc. can be by the resignings on lid Hole enters inside scale base, invades damage component, especially big to the damage of circuit board, influences the normal use of component, reduces The service life of electronic scale.

Summary of the invention

The utility model provides a kind of electronic scale that waterproof insectproof effect is good, can be effectively prevented from water, worm, sundries etc. into The problem of damaging component in scale base is invaded after entering scale base, guarantees that electronic scale works normally, can effectively extend electronic scale uses the longevity Life.

In order to solve the above technical problems, the utility model adopts the following technical solution: a kind of electricity that waterproof insectproof effect is good Sub- scale, including scale base and the scale pan, scale base include pedestal, the gravity sensitive device assembly being mounted in pedestal, the lid covered on pedestal Body, the bottom of the scale pan are equipped with connecting column, open up the relief hole passed through for connecting column on lid, the scale pan is located on scale base and passes through company It connects column to connect with gravity sensitive device assembly, wherein be equipped with opening up collection box, the gravity sensor group in the scale base Part is mounted in collection box, and the relief hole is in the vertical opening for projecting and entirely falling in collection box.

Under the premise of not influencing gravity sensor component operation, water, worm, the sundries etc. in scale base are entered from relief hole Can fall in collection box, and be collected by collection box, avoid these invaders move freely in scale base caused by The impaired problem of other components specifically avoids wiring board dampness, is damaged, guarantees that electronic scale works normally, can effectively prolong The service life of long electronic scale.

As an improvement, the bottom wall of the collection box is equipped with to the hollow drainage column extended outside collection box, the row One end of water column is connected to collection box, and the other end is pierced by pedestal.After water, worm, sundries are collected in collection box, it can pass through To being discharged outside scale base, especially the water energy in collection box is enough discharges drainage column in time, avoids collection box inner product dilutional hyponatremia And from aperture position to excessive problem, further ensuring the components such as the wiring board in scale base will not make moist easily, be damaged.

As improving again, the exterior bottom wall of the pedestal is equipped with drainage trough, and the outer end of the drainage column is at least partly set In in drainage trough.The water energy discharged from drainage column is enough to be flowed along drainage trough, can be shortened the length of drainage column, be reduced row The difficulty of processing of water column reduces processing cost, additionally it is possible to the water being discharged out of collection box be avoided to flow wantonly in the outer surface of pedestal Dynamic problem, convenient for cleaning；Moreover, drainage trough is other than the function of drainage, moreover it is possible to which the effect for playing limit makes drainage column Installation site is stable, reliable.

As improving again, the inner bottom wall of the collection box is equipped with one and encloses receipts ditch to lower recess, the drainage column with The receipts ditch connection.Ponding in collection box, which preferentially stores, to be received in ditch, overcomes tension to arrange in time, smoothly conducive to ponding Out；The formation moreover, inner bottom wall that receipts ditch is collection box is recessed downwards, that is to say, that receive ditch lower than the gravity in collection box Sensor module and other mounting structures (such as connection structure of collection box and the connection structure of pedestal, collection box and lid), These structures can be effectively prevented to impregnate in water.

As an improvement, the profile of the collection box and the outer profile of the gravity sensitive device assembly are adapted.Collection box Compact-sized, the space occupied is small.

As an improvement, the top surface of the collection box is bonded with the bottom surface of the lid, the top margin of the collection box is higher than institute State top surface 3mm~5mm of gravity sensitive device assembly.The bottom surface of lid has covered the opening of collection box, so that falling from relief hole Water, worm, sundries for falling etc. can be closed in collection box, avoid in scale base other components dampness, impaired effect more It is good, moreover, there are the differences in height of 3mm~5mm between the top margin of collection box and the top surface of gravity sensitive device assembly, it is gravity sensitive Space has been reserved in floating up and down for device assembly.

As an improvement, the plastic part that the collection box is integrally formed.Collection box it is easy to process, at low cost.

As an improvement, the pedestal is equipped with screw base, the collection box is equipped with corresponding screw hole, wears in screw hole If the first screw, the gravity sensitive device assembly includes sensor and the bracket for installing sensor, the head of the first screw It is locked after sequentially passing through bracket and screw hole with screw base, gravity sensitive device assembly and collection box is fixed on the base.Weight Force sensor module, collection box, pedestal connection structure simple and stable, and be it is dismountable, convenient for the cleaning of collection box and clear Reason.

As an improvement, being equipped with screw pole in the collection box, corresponding screw hole is opened up on the lid, and the is worn on screw hole Two screws, the head of the second screw cooperate after passing through screw hole with screw pole.Collection box is connect with lid, so that the position of collection box It is more reliable and more stable, and collection box and the connection structure of lid are simply firm.
