Embodiment 1

[0033] like figure 1 As shown, a medicine spoon for accurate weighing and sample addition includes a spoon head 101 and a handle 103. The inside of the handle 103 has a cavity along its length direction, and the cavity is provided with a clutch locking device, which is A self-locking device through which the spoon head is detachably connected to the handle. The internal cavity of the handle 103 is also equipped with a vibration motor 102 , a pressure sensor 106 , a control circuit board 107 , a charging circuit device, a lithium rechargeable battery 108 and a USB socket 109 .

[0034] The charging circuit device is integrated on the control circuit board 107, and the control circuit board 107 is respectively connected with the vibration motor 102, the pressure sensor 106, the lithium rechargeable battery 108 and the 5-volt USB socket 109; the charging circuit device is located inside the control circuit board , and charge the lithium rechargeable battery 108. The battery vol...

Abstract

The invention discloses a medicine spoon for accurate weighing and sample addition. The medicine spoon comprises a spoon head, a handle and a vibration device arranged in the cavity of the interior ofthe handle, wherein the cavity of the interior of the handle is also provided with an adjusting device and a control device connected with the vibration device and the adjusting device; the adjustingdevice is used for adjusting the vibration intensity required by the medicine spoon and sends sending an adjusting signal to the control device; and the control device is used for treating a receivedadjusting signal to adjust the vibration intensity of the vibration device, thereby controlling the vibration strength of the handle. According to the invention, during accurate weighing of a powdersubstance, through vibration of the vibration device, the fluidity of the powder substance is reinforced; the sample addition speed and the sample addition amount of the powder substance can be conveniently controlled; the situation that an excessive addition amount of the powder substance is added is not generated during weighing of the powder substance; and repeated weighing operation due to excessive sample addition is greatly reduced.

Description

technical field [0001] The invention relates to a chemical analysis device used for taking and weighing powdery substances, which can avoid cross-contamination, in particular to a medicine spoon for accurate weighing and adding samples. Background technique [0002] In chemical and physical analysis laboratories, medicine spoons are usually used to take and weigh powdery substances. Especially when weighing accurately, one must be accurate and fast, and the other is to prevent cross-contamination. The usual experimental steps are: prepare the balance, put the weighing container (or weighing paper) on the balance tray, then take the powder material from the medicine spoon and add it to the container, when the weight is close to the requirement, pat the hand holding the spoon with your hand Wrist, so that the powder material is slowly added to the container to achieve the specified amount to balance the balance. When changing a variety or batch number to weigh, it is usually ...
