[0002] Dental chairs, also known as dental chairs, are chairs specifically used for oral surgery and examination and treatment of oral diseases. This type of chair is usually designed to be very comfortable so that patients can feel as comfortable as possible during dental treatment. Dental chairs are an integral part of dental treatment, providing a comfortable and convenient treatment environment for doctors and patients.

[0003] Dental chairs usually have multiple functions. Usually, dental chairs are equipped with saliva aspirators, quick-release connectors and other components. Each time the dental chair is turned on and used, the quick-release connector is required to extract and discharge the clean water retained in the dental chair. Otherwise, bacteria will grow due to the retained clean water, and cross infection is likely to occur during treatment.

[0004] In the prior art, medical staff remove the retained clean water by making a simple collection bucket. The collection bucket is provided with a collection cavity, and the medical staff holds a quick-release joint and inserts it into the pre-opened hole in the collection bucket to let the retained clean water in the dental chair flow into the collection bucket. In this process, the quick-release joint is inserted into the hole and enters the collection bucket to contact the collected clean water, which is easy to be infected by bacteria growing in the collection bucket. When the quick-release joint is taken out for treatment, it is easy to cause bacterial cross-infection in the patient's mouth, causing secondary damage to the patient.

The drainage seat 2 is detachably arranged at the upper end opening of the barrel body 1, and the barrel cover 3 is adapted to the upper end of the barrel body 1; wherein:

[0030] The upper end of the drainage seat 2 is recessed downward to form a receiving cavity for receiving the retained water. A water outlet is provided at the bottom of the drainage seat 2. The water outlet is inclinedly provided with a hollow extension portion 22. The upper end of the hollow extension portion is butted with the water outlet, and the lower end portion extends close to the barrel body 1 toward the side wall. The hollow extension portion 22 is connected with the receiving cavity to form a recovery path for the retained water to be recovered into the barrel body 1. The retained water flows out from the lower end portion of the hollow extension portion 22 and flows down along the inner wall of the barrel body 1 into the barrel body 1.

[0031] A water extraction hole 11 is provided on the upper portion of the side wall of the barrel body 1 .

[0032] Specifically, when the retained water is recovered into the barrel body 1, it is necessary to use an external negative pressure pump body to connect the catheter to the barrel body 1 through the water pumping hole 11, and ensure that the end of the catheter extends to the bottom wall of the barrel body 1, so as to ensure that while the retained water in the barrel body 1 is recovered, it can be simultaneously exported to ensure that there is enough free volume in the barrel body 1 to recover the retained water, so as to ensure that the recovery work proceeds normally.

[0033] In one embodiment, the inner side wall at the upper end of the barrel body 1 is recessed with a plurality of bearing notches 12, and the upper end of the bearing notch 12 is flush with the opening; the side wall along the circumferential direction of the drainage seat 2 is provided with a plurality of snap-in blocks 21 used in conjunction with the bearing notch 12, and the snap-in blocks 21 are snapped into the bearing notch 12 and the bottom of the snap-in blocks 21 is in contact with the bottom of the bearing notch. The drainage seat 2 can be installed at the top opening position in the barrel body 1 through the bearing notch 22 and the snap-in blocks 21. On the contrary, the drainage seat 2 can be lifted up to remove the snap-in blocks 21 from the bearing notch 12, and the drainage seat 2 can be separated from the barrel body 1. Regular disassembly is performed to facilitate disinfection and cleaning operations on the barrel body 1 and the drainage seat 2.

[0034] In one embodiment, the lower end of the hollow extension portion 22 is an arc-shaped structure.

[0035] Specifically, the lower end of the hollow extension portion 22 is configured to be an arc-shaped structure, mainly to match the inner wall structure of the barrel body 1 to ensure that the retained water flows out in a circular structure and flows down along the inner wall of the barrel body 1 .

[0036] In one embodiment, a plurality of leakage gaps are provided on the bottom wall of the lower end of the hollow extension portion 22. The utility model provides a plurality of leakage gaps so that when the retained water flows out along the hollow extension portion 22, in addition to flowing out from the end opening to the inner wall of the barrel body 1 to realize wall flow, it also flows out from the plurality of leakage gaps, thereby accelerating the flow amount of the treatment water and thus increasing the flow speed.

[0037] In one embodiment, the outer wall of the upper end of the barrel body 1 is provided with threads, and the barrel cover 3 is threadedly connected to the upper end of the barrel body 1 .

[0038] In one embodiment, the upper end surface of the barrel cover 3 is recessed downward to form a pit, and an opening for docking with a dental chair quick-release joint is provided at the center of the pit; two L-shaped extension rods 31 are symmetrically fixed on both sides of the upper end of the barrel cover 3, and the upper ends of the two L-shaped extension rods 31 are connected by a guide seat 32, and the side wall of the guide seat 32 is provided with a U-shaped clamping notch that is directly opposite to the opening up and down, and the U-shaped clamping notch is used to clamp the tube wall of the dental chair quick-release joint.

[0039] Specifically, when the quick-release joint pushes the retained water into the accommodating cavity, a U-shaped clamping notch can be used to clamp the tube wall of the quick-release joint, while ensuring that the opening at the end of the quick-release head is exactly aligned with the opening position of the barrel cover 3, without the need to manually hold the quick-release joint.

[0040] In one embodiment, the bottom of the barrel body 1 has a protrusion 13 extending toward the inside of the barrel body, and the protrusion is provided with a threaded groove extending upward from the bottom of the barrel body, and the top of the threaded groove is close to the top of the protrusion; a support rod 41 is threadedly connected in the threaded groove, and the bottom end of the support rod 41 extends out of the threaded groove and is fixedly connected to the chassis 4.

[0041] like Figure 5 As shown, the chassis 4 is used as a supporting base. When in use, according to the use needs of medical staff, the barrel body 1 is rotated by holding the barrel body 1, and the height of the protrusion 13 is adjusted along the axial direction of the support rod 41 to adjust the recovery height of the barrel body 1, so that the dentist can hold the quick-release joint to squeeze the retained water into the accommodating cavity, avoiding the need for medical staff to bend down to lower the quick-release joint close to the opening of the barrel cover 3 due to the barrel body 1 being placed too low, which easily causes fatigue to the dentist. Therefore, the height of the barrel body 1 can be adjusted, which is convenient for medical staff in daily use, without bending down to align the quick-release joint with the pre-opened opening of the barrel cover 3, and quickly and accurately recover the retained water into the barrel body 1.

[0042] like Figure 1As shown, by adding a barrel cover 3 threadedly connected to the barrel body 1, after being installed on the barrel body 1, the inner top wall of the barrel cover 3 is seated on the drainage seat 2 to ensure that the drainage seat 2 does not shake. When recovering the retained water, align the end of the quick-connect joint with the opening to push the retained water into the receiving cavity of the drainage seat 2, and use the inner top wall of the barrel cover 3 as an annular closed enclosure to prevent the retained water from splashing when it hits the side wall of the receiving cavity above the drainage seat 2.

[0043] Before using the dental chair, it is necessary to extract the retained water in the dental chair through the quick-acting joint to ensure the normal use of the dental chair. The water outlet of the quick-acting head is aligned with the drainage seat 2 set at the upper end opening of the barrel body 1, and the retained water is pumped into the accommodating cavity. The hollow extension part 22 is connected with the accommodating cavity to form a recovery path for the retained water to be recovered into the barrel body 1. The retained water flows out from the end of the hollow extension part 22 and flows down along the inner wall of the barrel body 1 to the inner bottom wall of the barrel body 1. During this process, the retained water will not splash.

[0044] The retained water recovery method of the utility model changes the water flow direction of the retained water recovered into the barrel 1, on the one hand, it prevents the quick-acting joint from being inserted into the barrel 1 and contacting the recovered retained water, causing the quick-acting joint head to be infected by bacteria, thereby preventing the quick-acting joint from causing bacterial cross-infection in the patient's oral cavity when used for treatment operations, causing secondary harm to the patient. On the other hand, it can prevent the retained water from splashing on the floor of the dentist's office during the recovery process, requiring medical staff to clean it up.
