Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

Embodiment 1, as shown in fig. 1 to 3, this embodiment aims to provide a couplant applicator for B-ultrasonic examination, which is convenient to heat a couplant and use, and in order to achieve the above object, the couplant applicator for B-ultrasonic examination provided by this embodiment includes a couplant bottle 1 and an apparatus body 2 for inserting the couplant bottle 1, the apparatus body 2 is in a barrel shape, the outer diameter of the apparatus body 2 is mainly convenient for a human hand to hold, a vacuum negative pressure pump 3 is provided in the apparatus body 2, the vacuum negative pressure pump 3 includes a containing cavity made of an elastic material, a check valve (a check valve only allowing entry) is provided at an inlet of the containing cavity, a check valve (a check valve only allowing exit) is also provided at an outlet of the containing cavity, so that when the containing cavity is squeezed, air or the couplant in the containing cavity is discharged through the outlet, and the containing cavity is reset because the containing cavity is made of the elastic material, negative pressure is generated in the cavity, and the couplant in the couplant bottle 1 is sucked out, therefore, a feed inlet of the vacuum negative pressure pump 3 is communicated with an outlet of the couplant bottle 1. Still be provided with extruded article 4 in one side of vacuum negative pressure pump 3, extruded article 4 is whole to be the slice setting, its most runs through the device body 2 and sets up outward, being in a part of device body 2, the coupling between extruded article 4 and the device body 2, thus, when inwards pressing extruded article 4, the extrusion produces the extrusion to the appearance chamber of vacuum negative pressure pump 3, make vacuum negative pressure pump 3 accomplish the discharge action, in order to make extruded article 4 under the condition of not having other effort, lose the extrusion to extruded article 4, be provided with rebound spring 5 between extruded article 4 and the device body 2, of course, also can adopt the torsional spring to realize. In order to make the chamber quick reset, extrusion piece 4 is connected the setting with vacuum negative pressure pump 3, like this, under extrusion piece 4's drive, can make the chamber quick reset, vacuum negative pressure pump 3 is used in the toothpaste squeezer now more, so in this embodiment, do not add the detailed description to it, in this embodiment, in order to be that extrusion piece 4 can extrude more gas, vacuum negative pressure pump 3 sets up the one end of keeping away from extrusion piece 4 in the chamber.

In order to make the probe can make things convenient for even coating more, in this embodiment, vacuum negative pressure pump 3's discharge gate 311 runs through the bottom of device body 2, bottom at device body 2 is provided with ejection of compact arch 21, the bottom of the protruding 21 of ejection of compact is provided with guide way 22, vacuum negative pressure pump 3's discharge gate 311 sets up the bottom at guide way 22, such setting, the couplant that the messenger extruded no longer is the form that sticks together, but rectangular form, thus, when using, the probe just can one section use, can ensure the even of coating, the tradition setting of the form that sticks together, when the probe removes for the first time, can take away a large amount of couplant, and then lead to the inconvenient use in later stage. The coating is changed from lump shape to strip shape, so that the coating uniformity can be ensured, and the use amount can be reduced.

In order to heat the couplant, in the present embodiment, an electric heating unit 6 is provided on the side wall of the apparatus body 2. The electric heating assembly 6 mainly adopts the structural arrangement of the existing commonly used electric heating sheet, after the plug transforms voltage to 5V, the surface of the couplant bottle 1 is heated, and the distance between the couplant bottle 1 and the device body 2 is about two fifths, so that the couplant at the outlet of the couplant bottle 1 is heated, and the coating is avoided.

Considering that the couplant bottle 1 and the vacuum negative pressure pump 3 are preferably in a sealed state, so that negative pressure adsorption can be better realized, a feeding member 7 is further arranged between the couplant bottle 1 and the vacuum negative pressure pump 3, the feeding member 7 comprises a contact part 71 arranged in a barrel shape and a material guiding conical pipe 72 arranged at the bottom of the contact part 71, the material guiding conical pipe 72 is communicated with the contact part 71, a sealing gasket is arranged on the inner wall at the bottom of the contact part 71, the feeding member 7 is in threaded connection with the device body 2, so that sealing is realized by matching with the sealing gasket under the action of the weight of the couplant bottle 1, and the shape of the material guiding conical pipe 72 is mainly used for matching with a conical outlet pipe of the couplant bottle 1.

Considering that a tapered outlet pipe of the couplant bottle 1 needs to be partially removed during use, and because the removed size is different, a seal between the material guiding cone 72 and the vacuum negative pressure pump 3 needs to be considered, for this reason, the vacuum negative pressure pump 3 provided in the present embodiment includes a pump body portion 31 (the aforementioned structure) and a connecting portion disposed above the pump body portion 31, the connecting portion includes a casing 32 having a tubular shape and a connecting cone 33 disposed in the casing 32, the connecting cone 33 communicates with the pump body portion 31, and a sealing gasket is disposed on an inner wall of the connecting cone 33. The outer shell 32 is mainly used for fixing, and the connecting conical pipe 33 can be sealed with the guide conical pipe 72, so that the cutting of the outlet pipe has no influence.

In order to fix the connecting part, a connecting part 8 is further arranged between the feeding part 7 and the vacuum negative pressure pump 3, the connecting part 8 is in a tubular shape, an internal thread is arranged in the connecting part and used for fixing the connecting part with the shell 32, and the connecting part 8 is in threaded connection with the device body 2 in order to fix the connecting part 8.

Through foretell setting, when using, with whole device circular telegram, then, continuously heat the couplant of couplant bottle 1 bottom, then, utilize extruded article 4 extrusion can, because the interval of the time of B ultrasonic inspection, for this reason, have certain heating time, can ensure the continuation of work.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
