The utility model discloses still another aim at provides a saliva pipe is inhaled in amortization, and its end is equipped with the function that a plurality of enlarged chambeies can play the decay sound wave, can prevent again that the return bend from blockking up.

In order to achieve the above object, the utility model adopts the following technical scheme, include:

the device comprises an elbow pipe, a plurality of suction nozzles and a suction nozzle, wherein a pipe cavity is arranged in the elbow pipe, a plurality of expansion cavities are arranged at the middle rear part of the elbow pipe, and a joint is arranged at the tail end of the elbow pipe and used for stretching into the oral cavity to suck saliva;

the silencing shell is covered at the middle rear part of the bent pipe, a silencing cavity is formed between the inner wall of the silencing shell and the outer wall of the bent pipe, and a transmission hole is formed in the upper end of the silencing shell;

the plurality of silencing plates are uniformly distributed in the silencing cavity, and vent holes are formed in the silencing plates; and

wherein, the vent holes on the adjacent acoustical panels are arranged in a crossed manner.

Preferably, the expansion cavity is spherical, and the maximum diameter of the expansion cavity is 1.2-1.5 times of the diameter of the bent pipe.

Preferably, the number of the expansion cavities is 11-15.

Preferably, the front part of the elbow pipe gradually converges, and a rounded structure is arranged at the front end of the elbow pipe.

Preferably, the sound-absorbing plate is made of sound-absorbing cotton.

Preferably, the joint is made of a flexible material.

The beneficial effects of utility model are that: the noise reduction shell with multiple layers of noise reduction plates is arranged outside the bent pipe, so that noise can be effectively reduced; the tail end of the bent pipe is provided with a plurality of expansion cavities, so that the saliva can flow out, the blockage is prevented, sound waves can be attenuated, and the noise reduction is assisted.

Detailed Description

The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.

It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

As shown in fig. 1-2, an implementation form of the present invention, in order to achieve the above object, adopts the following technical solution, including:

the elbow 110 is a tubular structure made of metal or polymer material, the inside of the elbow 110 is provided with a tube cavity 111, the end of the elbow 110 is provided with a plurality of expansion cavities 112, and the end of the elbow is provided with a joint 140 for extending into the oral cavity to suck saliva. Preferably, the elbow 110 is made of a stainless steel material. Preferably, the expansion cavity 112 is spherical, and the maximum diameter of the expansion cavity 112 is 1.2 to 1.5 times of the diameter of the bent pipe.

The sound-deadening shell 120 has a cylindrical tubular structure. The muffler shell 120 covers the middle rear portion of the elbow pipe 110, a muffler chamber 121 is formed between the inner wall of the muffler shell 120 and the outer wall of the elbow pipe 110, and a transmission hole 122 is formed at the upper end of the muffler shell 120.

A plurality of silencing plates 130 are uniformly distributed in the silencing cavity 121, and vent holes 131 are formed in the silencing plates 130. Preferably, the sound-absorbing plate is made of sound-absorbing cotton. More preferably, the ventilation holes 131 of the adjacent sound-absorbing plates 130 intersect with each other.

In the using process, the joint 140 is connected with a suction device pipeline on the dental chair, then the bent pipe 110 is inserted into the oral cavity of a patient, the front end of the bent pipe 110 is abutted to the tongue, the air pump is started to suck saliva, in the process, sound waves reach the inner part of the sound attenuation cavity 121 through the wall of the bent pipe 110, are blocked by the sound attenuation plate 130 in the sound attenuation cavity 121, are attenuated layer by layer, and are discharged from the transmission hole 122.

In another embodiment, the enlarged lumen 112 is spherical, and the maximum diameter of the enlarged lumen 112 is 1.2 to 1.5 times the diameter of the elbow. In this range, suction for sucking saliva is ensured, and blockage of the tube cavity 111 can be effectively prevented.

In another embodiment, the number of the expansion cavities 112 is 11 to 15. Preferably, the number of the expansion cavities is 13.

In another embodiment, the front portion of the elbow 110 is tapered, and a rounded structure is provided at the front end of the elbow 110. The rounded structure can prevent pressure sores.

In another embodiment, the sound absorbing panel 130 is made of sound absorbing cotton.

In another embodiment, the joint 140 is made of a flexible material.

To sum up, the noise reduction and saliva absorption tube 1 of the utility model has the advantages that the noise reduction shell 120 with the multilayer noise reduction plate 130 is arranged outside the elbow 110, so that noise can be effectively eliminated; the end of the bent tube 110 is provided with a plurality of expansion cavities 112, which can help saliva flow out, prevent blockage, attenuate sound waves and assist in noise reduction.

While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
