Description

Portable color ultrasound instrument with keyboard pollution discharge function

Technical Field

The invention relates to a portable color ultrasonic instrument, in particular to a portable color ultrasonic instrument with a keyboard pollution discharge function.

Background

The portable color ultrasonic instrument mainly comprises a host, and a display screen, a power supply module and an ultrasonic probe which are respectively and electrically connected with the host. The display screen is generally hinged to one side of the host machine and can be matched with the host machine for folding storage. The upper surface of the host computer is provided with a man-machine interaction operation module, such as a keyboard, a track ball and the like. The display screen is touched after being stored so as not to make the keyboard protrude from the surface. The host computer is provided with a concave key platform at the position for installing the keyboard, and keys are arranged and installed on the key platform.

Although the portable color ultrasonic instrument generally works in an aseptic or relatively clean environment, fine substances such as dust and the like are inevitably deposited and remained in the keyboard after the portable color ultrasonic instrument is used for a long time. Generally, a vacuum cleaner is used to suck the keyboard, but the operation is easy to press the key, and the operation cannot be performed in a power-on state. And the top adsorption mode, the negative pressure end of dust catcher has great clearance with the button platform for suction greatly reduced, and the blowdown effect is not obvious.

Disclosure of Invention

The invention aims to provide a portable color Doppler ultrasound instrument with a keyboard pollution discharge function, so as to solve the problems in the prior art.

The invention relates to a portable color Doppler ultrasound instrument with a keyboard pollution discharge function, which comprises a host, wherein the host is provided with a key platform for arranging and installing keys; the key platform is downwards sunken on the upper surface of the host; a sewage discharge pipeline is arranged in the main machine, an air path joint is arranged at one end of the sewage discharge pipeline, and the air path joint is arranged on the side wall of the main machine; the branch of the sewage discharge pipeline far away from the air passage joint extends to the key platform respectively, is exposed above the key platform and is positioned below the key; the exposed part of the sewage discharge pipeline at the key platform is provided with a plurality of suction holes.

The sewage discharge pipeline comprises a plurality of branch pipes which are transversely distributed and a gas collecting pipe which is longitudinally arranged; each branch gas pipe is correspondingly arranged below one row of keys, one end of each branch gas pipe is communicated with the gas collecting pipe, and the other end of each branch gas pipe extends freely; the gas collecting pipe is communicated with all the branch gas pipes and the gas circuit connector at the same time.

A suction hole is arranged below each key.

The distances between the suction holes and any two sides of the corresponding keys are different.

The portable color Doppler ultrasound instrument with the keyboard pollution discharge function has the advantages that the portable color Doppler ultrasound instrument can be externally connected with a dust collector through the air path connector, can directly absorb fine matters such as dust on the key platform under the condition of not touching the keys, and can be operated under the state that the host computer is started. And the actual position of negative pressure and the absorbed target distance are obviously reduced, and the sewage discharge efficiency and the cleanliness are improved. The unequal distance arrangement of suction hole and button can also form asymmetric air current between button and button platform when the negative pressure takes place, raises the dust more easily and inhales the pipeline and discharges away.

Detailed Description

As shown in fig. 1-5, the portable color Doppler ultrasound instrument with keyboard dirt discharging function according to the present invention comprises a main unit 10, wherein the main unit 10 is provided with a key platform 12 for arranging and installing keys 11. The key platform 12 is recessed downward from the upper surface of the host 10. The main machine 10 is internally provided with a sewage discharge pipeline, one end of the sewage discharge pipeline is provided with an air path joint 21, and the air path joint 21 is arranged on the side wall of the main machine 10. The branch of the sewage draining pipeline far away from the air path joint 21 extends to the key platform 12 respectively, and is exposed above the key platform 12 and below the key 11. The exposed part of the sewage draining pipeline at the key platform 12 is provided with a plurality of suction holes 24.

The sewage draining pipeline comprises a plurality of branch pipes 22 which are transversely distributed and a gas collecting pipe 23 which is longitudinally arranged. Each air branch pipe 22 is correspondingly arranged below one row of keys 11, one end of each air branch pipe is communicated with the air collecting pipe 23, and the other end of each air branch pipe freely extends. The gas collecting pipe 23 is communicated with all the branch gas pipes 22 and the gas circuit connector 21.

A suction hole 24 is arranged below each key 11, so that the lower part of each key 11 can be effectively drained. The suction hole 24 is arranged below the key 11, and can play a role of beauty, when the user watches from the outside of the main machine 10, the key 11 directly shields the suction hole 24, and the user can not directly see the suction hole 24.

The suction holes 24 are not equal to the distances between any two sides of the corresponding keys 11. Taking a suction hole 24 and its corresponding key 11 as an example: the distance from the suction hole 24 to the upper edge of the key 11 is a1, the distance to the lower edge is a2, the distance to the left edge is a3, and the distance to the right edge is a4, then a1< a2< a3< a 4. When negative pressure occurs, four cyclones with different diameters are generated at each suction hole 24 and the four sides of the corresponding key 11. The cyclone diameter is different, and its velocity of flow also is different, and dozens of buttons 11 all around in the keyboard produce this air current phenomenon. The cyclones with different flow rates collide with each other to violently lift dust on the key platform 12 and also violently impact the bottom surface of the key 11, so that the suction process is more effective than the symmetrical arrangement.

The working principle of the portable color Doppler ultrasound instrument with the keyboard pollution discharge function is that when keyboard dust needs to be sucked, a negative pressure device such as a dust collector is externally connected through the air path connector 21, and negative pressure is transmitted to each suction hole 24 through the air path connector 21, the gas collecting pipe 23 and the branch gas pipe 22. The suction holes 24 suck the dirt nearby, and under the condition that the keys 11 are not touched, the dust attached to the upper surface of the key platform 12 and/or the lower surface of the keys 11 is effectively sucked away, so that the keyboard pollution discharge function is realized.

It will be apparent to those skilled in the art that various other changes and modifications may be made in the above-described embodiments and concepts and all such changes and modifications are intended to be within the scope of the appended claims.
