Description

Combined regulator of electronic pipettor

Technical Field

The invention relates to the technical field of pipettors, in particular to a combined regulator of an electronic pipettor.

Background

Conventionally, electronic pipettes are regulated and controlled by push-buttons. For example, volume adjustment is typically performed in this manner. A standard embodiment is an arrow key with which the adjustable volume is increased or decreased. With few exceptions, the same arrow keys are also used for other functions, such as for advancing in a menu. Conventionally, a single touch of an arrow key results in a change in one adjustment step, and prolonged pressing of the key results in an accelerated change in the reading. However, the regulation thus implemented has drawbacks. The adjustment is not too fast, at least in the case where the adjustment target value is far from the initial reading. Obviously, many new techniques have been introduced at present, including means of adjusting wheel, combination keys, etc. for solving the above problems, but there are still disadvantages, such as the adjusting wheel of an electronic pipette described in document CN104185509B, the main disadvantages are:

1. the structure is too complicated, the manufacturing difficulty is large, and the production is not facilitated. Because the pipettor is a handheld device, the pipettor is small in size and operated by a single hand, the internal space of the pipettor is necessarily limited, two magnets, a magnetic sensor and two torsion springs are required to be installed in the limited space, and meanwhile, the necessary installation precision and good operation experience are very difficult to ensure;

2. are susceptible to interference. Due to the adoption of the magnet and the magnetic sensor, the magnetic sensor is easily interfered in a use environment close to magnetism, and the normal operation of a machine is influenced;

3. the single fine adjustment is laborious and time-consuming. If the reading range which the user needs to adjust is small, the reading range is not suitable for a mode of changing the reading in an accelerated mode, because the reading range is easy to exceed or be lower than the expected reading range, the user needs to adjust in a singular number, the operation mode is that the adjusting wheel needs to be rotated firstly and then released quickly, the corresponding reading is changed once, and if the reading which needs to be changed has a certain amount, the user needs to repeatedly perform the operation of rotating and releasing, and the operation is complicated; the reason for the defects is that although the scheme easily realizes fine adjustment and quick adjustment, in practical use, the quick adjustment speed is far higher than the human reflection speed, so that the target adjustment value is difficult to reach through one-time quick adjustment, the operation result is often over or under the expected reading, and the user is required to repeatedly adjust the target adjustment value back and forth and perform fine adjustment of reading at the moment;

in document CN105233895A, a combination knob and an electric pipette including the same are described, and the main disadvantages are:

1. the structure is complex;

2. no support is provided for fast adjustment readings;

3. due to the combination keys, the combination keys are not easy to master by a user, and the user cannot intuitively know the function represented by each key operation.

Therefore, the present inventors have earnestly demanded to conceive a new technology to improve the problems thereof.
