Description

Double-bending three-purpose spray gun nozzle structure convenient for deep cleaning

Technical Field

The utility model relates to the field of dental oral treatment, in particular to a double-bending three-purpose spray gun spray head structure convenient for deep cleaning.

Background

A three-purpose spray gun is a cleaning tool for dental oral treatment for spraying water or air into the oral cavity of a patient. Generally, when a treatment step is completed, the oral cavity needs to be thoroughly cleaned, and a water spraying function is used, and when the oral cavity needs to be locally dried during the treatment (such as after an endodontic step of root canal treatment), a water spraying function (water and air) is used when the oral cavity needs to be wet or locally cleaned during the treatment. Wherein, when spraying the water mist, the spray pressure of the three-purpose spray gun can be regulated, so that the size of atomized liquid drops can be controlled, and more cleaning in different modes can be performed.

The existing three-purpose spray gun spray head is provided with a bending part close to an angle of 135 degrees at a position 2.5cm away from the tail end of the spray head, so that dirt generated during oral treatment is conveniently washed and cleaned in a limited oral cavity space, but from the practical use effect, the bending angle of the bending part is insufficient, deep oral cavity cleaning cannot be provided, the treatment effect and efficiency are poor, and the bending angle of the bending part is increased to cause the inner pipe line at the bending position to be narrow, so that the water and gas passing is influenced.

Aiming at the defects of the prior art, the utility model provides a double-bending three-purpose spray gun spray head structure convenient for deep cleaning, which solves the problems that the bending angle of the bending part of the traditional three-purpose spray gun spray head is insufficient, deep oral cavity cleaning cannot be provided, the treatment effect and efficiency are poor, and the inner pipe line at the bending part is narrow due to the increase of the bending angle of the bending part, so that the passing of water and gas is influenced.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

The utility model provides a dual bending three-purpose spray gun shower nozzle structure convenient to degree of depth clearance, includes outer tube and inner tube, outer tube one end is the interface end, and the outer tube other end is the spout end, spout end extension is equipped with first bending portion, first bending portion wherein one end extension is equipped with the second bending portion, the inner tube extends coaxial sleeve along outer tube length direction and establishes in outer tube lumen, and the lumen of inner tube is as the rivers passageway, and the cavity between inner tube and the outer tube is as airflow channel, and inner tube wherein one end extends to the interface end outside.

As a preferable embodiment of the present utility model, a bending angle between the outer tube and the first bending portion is 155 degrees to 165 degrees.

In a preferred embodiment of the present utility model, a bending angle between the first bending portion and the second bending portion is 125 degrees to 135 degrees.

Compared with the prior art, the utility model has the beneficial effects that:

According to the utility model, through the arrangement of the first bending part and the second bending part in a matched manner, the operation of doctors during treatment is labor-saving, the nozzle of the nozzle structure is better aligned to the treatment part in the oral cavity of a patient, so that the treatment part can be deeply cleaned, the effect and the efficiency of the oral cavity treatment of the patient are greatly improved, and meanwhile, the smooth passing of water and air channels in the nozzle structure is not influenced.
