Description

Technical Field

[0001] This utility model relates to the field of spittoon technology, and in particular to a dental spittoon. Background Technology

[0002] In dental treatment, the dental chair spittoon plays a crucial role. It is primarily used for patients to rinse their mouths and spit out blood, debris, or disinfectant residue generated during treatment. It is an indispensable auxiliary device in dental procedures. Its presence greatly ensures the smooth progress of dental treatment, creating a relatively clean and hygienic treatment environment for both patients and dentists.

[0003] However, most dental chair spittoons on the market currently have limited functionality, merely serving the basic purpose of collecting water and debris. In actual use, the water spit out by patients often contains various gases. When these gases, along with the water, are discharged into the drain pipe, they create obstructions. The gas occupies space, narrowing the water flow path and significantly slowing the flow rate. Over time, this can lead to water accumulation in the spittoon, not only affecting its normal use but also potentially fostering bacterial growth and posing hygiene risks.

[0004] Furthermore, many dental spittoons are currently fixed directly to the frame, and often have a faucet or other device above them. Because patients vary significantly in height, these fixed spittoons make it extremely inconvenient for patients to reach for water. Taller patients may need to bend over excessively, while shorter patients may have to strain to reach them, undoubtedly increasing patient discomfort and impacting the efficiency and experience of treatment.

[0005] The technical content disclosed in the Chinese patent document (publication number: CN2788760Y, patent name: integral dental spittoon) is as follows: This utility model relates to an integral dental spittoon, which belongs to the field of medical device technology. Its main technical feature is that a spittoon fixing cavity is provided in one side of the outer shell, an L-shaped drain pipe is provided between the spittoon fixing cavity and the basin, and a fixing frame is installed in the spittoon fixing cavity.

[0006] As can be seen from the aforementioned patent documents, the L-shaped drain pipe design between the spittoon's fixed cavity and the basin in this dental spittoon lacks a dedicated channel for gas flow. This results in gas and water mixing and entering the drain pipe, preventing the gas from escaping smoothly and causing poor drainage. Over time, water easily accumulates in the basin, affecting the spittoon's normal use. Furthermore, because the basin is fixed, it cannot be flexibly adjusted according to the patient's height, causing inconvenience for patients of different sizes and failing to meet diverse usage needs, thus reducing the patient's overall experience. Utility Model Content

[0007] This invention overcomes the shortcomings of existing technologies and provides a dental spittoon. A water pipe receives a water-vapor mixture from a water-receiving component. Water and solid impurities flow downwards from the vertical pipe under gravity and are discharged into the drainage system, while gas is discharged through a vent pipe. When the spittoon is full, the internal air pressure of the vent pipe increases, which facilitates the faster discharge of wastewater from the vertical pipe, preventing gas accumulation inside the device and ensuring its normal operation. This achieves effective treatment of the water-vapor mixture. The flange allows the housing assembly to rotate around it, facilitating patient adjustment of the spittoon and water outlet positions. Neither the flange nor the entire spittoon has a non-removable fixed connection to the housing, facilitating future maintenance and replacement.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] A dental spittoon includes a flange seat, a water pipe rotatably connected to the flange seat, the water pipe including a tee, the tee including a water inlet pipe, a vent pipe at one end of the water inlet pipe and a water-receiving component at the other end; a vertical pipe body is connected directly below the water inlet pipe.

[0010] A spittoon is installed above the water-receiving component. The water vapor mixture received by the spittoon passes through the water-receiving component to the water-receiving pipe. Water and solid impurities flow down from the vertical pipe, while gas rises and is discharged through the vent pipe.

[0011] Furthermore, the flange seat is rotatably connected to a rotating seat, which is connected to a housing assembly, the housing assembly including an upper housing and a lower housing;

[0012] The water pipe is located inside the housing assembly.

[0014] Furthermore, the water-receiving component includes a water-receiving trough, one end of which is connected to a water outlet pipe, and an inner groove is provided between the water-receiving trough and the water outlet pipe;

[0015] The outlet pipe is inserted into the inlet pipe.

[0016] Furthermore, an outer ring and an inner ring are coaxially arranged at the center of the flange seat, the rotating seat is rotatably inserted into the outer ring, a rotation limit strip is provided on the outer periphery of the rotating seat, and the vertical pipe body is rotatably inserted into the inner ring; a limit block is provided at the bottom of the rotating seat, and a slot is provided at the bottom of the outer ring, and the limit block is inserted into the slot.

[0017] Furthermore, a first bearing is provided between the rotating seat and the outer ring, and a second bearing is provided between the vertical tube and the inner ring.

[0018] Furthermore, the flange seat is connected to a sealing assembly, which includes a first sealing ring and a second sealing ring. The first sealing ring is disposed between the rotating seat and the outer ring, and the second sealing ring is disposed between the vertical pipe body and the inner ring.

[0019] Furthermore, the flange seat is provided with several bolt fixing slots, and a retaining shaft is provided below the flange seat, with a reverse retaining ladder provided on the outer ring of the retaining shaft.

[0020] Furthermore, the flange seat is connected to the internal support plate, which is located inside the chassis.

[0021] Furthermore, the faucet connector is provided with a water outlet, which includes a faucet and a cup holder located directly below the faucet.

[0022] The spittoon is made of ceramic.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. A water-passing pipe is installed, which can receive the water-vapor mixture transmitted from the water-receiving components and perform preliminary separation. Water and solid impurities flow down the vertical pipe under gravity and are discharged into the drainage system, while the gas is discharged through the vent pipe, preventing gas accumulation inside the equipment, ensuring the normal operation of the equipment, and achieving effective treatment of the water-vapor mixture.

[0025] 2. A flange seat is provided, with an outer ring and an inner ring coaxially arranged at the center of the flange seat.

[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0037] like Figures 1 to 6 As shown, a dental spittoon can efficiently handle the water vapor mixture generated by patients, while providing a convenient user experience for both medical staff and patients. It includes a flange seat 6, which is further provided with several bolt fixing slots 603. The flange seat 6 is connected to an internal support plate 2 via bolts on the bolt fixing slots 603. The internal support plate 2 is housed within a casing 1.

[0038] The flange seat 6 is rotatably connected to a water pipe 9, which is the core flow component of the entire sputum cup system. It is housed within the box assembly 3, which includes an upper box 302 and a lower box 301, to accommodate the water pipe 9, protecting it and enhancing its appearance. Its function is to receive the water vapor mixture transmitted from the water-receiving component 901 and perform initial separation. The water pipe 9 includes a tee 902, which includes a water inlet pipe 9021. One end of the water inlet pipe 9021 is connected to a vent pipe 9023, and the other end is connected to the water-receiving component 901. A vertical pipe 9022 is connected directly below the water inlet pipe 9021. A sputum cup 5 is positioned above the water-receiving component 901. The sputum cup 5 is made of ceramic, which is wear-resistant, scratch-resistant, and easy to clean, maintaining its pristine appearance for a long time. The sputum cup 5 has a large opening at the top for easy spitting and rinsing by the patient. The water vapor mixture received by the spittoon 5 passes through the water-receiving component 901 and arrives at the water-receiving pipe 9021, achieving effective treatment of the water vapor mixture. Water and solid impurities flow downwards from the vertical pipe 9022, while gas rises and is discharged through the vent pipe 9023, preventing gas accumulation inside the equipment and ensuring its normal operation.

[0039] The water-receiving component 901 includes a water-receiving trough 9011, one end of which is connected to a water outlet pipe 9012. An inner groove 9013 is also provided between the water-receiving trough 9011 and the water outlet pipe 9012. The water outlet pipe 9012 is inserted into the water inlet pipe 9021. The inner groove 9013 can play a certain role in buffering and guiding the flow, ensuring that the water in the water-receiving trough 9011 flows fully to the water outlet pipe 9012, preventing water accumulation in the water-receiving trough 9011 from causing odor, and maintaining the cleanliness and hygiene of the equipment.

[0040] The flange seat 6 is rotatably connected to the rotating seat 7, which is connected to the box assembly 3. The box assembly 3 includes an upper box 302 and a bottom box 301. The water pipe 9 is disposed in the box assembly 3.

[0041] An outer ring 602 and an inner ring 601 are coaxially arranged at the center of the flange seat 6. The rotating seat 7 is rotatably inserted into the outer ring 602. A rotation limit strip 701 is provided on the outer periphery of the rotating seat 7. When the sputum cup 5 rotates, the rotation limit strip 701 will rub against the inner side of the outer ring 602 to ensure that the rotation is not too loose. A limit block 702 is provided at the bottom of the rotating seat 7. A slot 705 is provided at the bottom of the outer ring 602. The limit block 702 is inserted into the slot 705. The slot 705 is an arc-shaped groove. The arc length of the slot 705 limits the rotation angle of the limit block 702, thereby limiting the rotation angle of the rotating seat 7. This ensures that the sputum cup 5 can only rotate within a certain range, preventing the sputum cup 5 from rotating excessively and hitting objects or people, thus ensuring safety and convenience of use. The rotating seat 7 is connected to the box assembly 3. Through its rotation function, it can drive the box assembly 3, as well as the sputum cup 5 and the water outlet seat 4, to adjust their positions for the convenience of the patient.

[0042] The vertical tube 9022 is rotatably inserted into the inner ring 601. Therefore, the rotating seat 7 and the vertical tube 9022 are coaxially arranged, and from the outer surface, the box assembly 3 can rotate around the flange seat 6.

[0043] One end of the upper box 302 is equipped with a faucet connector 3021, and the other end is equipped with a spittoon connector 3022. The faucet connector 3021 also has a ventilation hole. The ventilation tube 9023 is enclosed inside the faucet connector 3021, and the gas output from the ventilation tube 9023 is dispersed through the ventilation hole. The faucet connector 3021 is equipped with a water outlet 4, which includes a faucet 401 and a cup holder 402 located directly below the faucet 401. The faucet 401 provides clean water for patients and medical staff, with a stable and moderate water flow to meet the needs of patients for rinsing their mouths. The cup holder 402 provides a convenient place to hold a water cup, making it more convenient for patients to use and improving the practicality and user-friendliness of the device. Therefore, rotating the box assembly 3 allows the spittoon 5 or the water outlet 4 to be closer to the patient, making it convenient for the patient to receive water for rinsing or spitting out the mouthwash.

[0044] A first bearing is installed between the rotating seat 7 and the outer ring 602. This first bearing ensures smoother rotation of the rotating seat 7, reduces frictional resistance, and extends the service life of the equipment. A second bearing is installed between the vertical pipe 9022 and the inner ring 601. This second bearing also ensures smoother rotation of the vertical pipe 9022, guaranteeing a smooth drainage process. Therefore, the rotation of both the rotating seat 7 and the vertical pipe 9022 is smoother.

[0045] The flange seat 6 is connected to the sealing assembly 8, which includes a first sealing ring 801 and a second sealing ring 802. The first sealing ring 801 is disposed between the rotating seat 7 and the outer ring 602 to fill the gap between them. The first sealing ring 801 is also disposed between the vertical tube body 9022 and the inner ring 601 to fill the gap between them. The sealing assembly 8 prevents leakage of water vapor mixture and also prevents the spittoon 5 from wobbling, ensuring the stability and sealing of the equipment and providing a clean and hygienic environment for patients and medical staff.

[0046] A retaining shaft 604 is provided below the flange seat 6. A reverse retaining ladder is provided on the outer ring of the retaining shaft 604. The center of the retaining shaft 604 is a through hole, which is used to drain the water and solid impurities discharged through the vertical pipe body 9022. When the retaining shaft 604 is connected to the water pipe, the reverse retaining ladder can prevent the water pipe from being dislodged.

[0047] During dental treatment, patients can rotate the housing assembly 3 to bring the spittoon 5 closer to themselves for spitting, rinsing, or rotate the water outlet 4 to a suitable position to collect water from the faucet 401, with the cup placed on the cup holder 402. The water vapor mixture produced by the patient is spat into the spittoon 5, collected in the water-receiving groove 9011 of the water-receiving component 901, and flows into the water inlet pipe 9021 through the water outlet pipe 9012. In the water inlet pipe 902, water and solid impurities flow downwards from the vertical pipe 9022 due to gravity, eventually draining into the drainage system; while gas rises and is discharged through the vent pipe 9023, then through the vent hole on the faucet connector 3021. When the spittoon is full, the internal air pressure in the vent pipe increases, which facilitates the faster discharge of wastewater from the vertical pipe. The entire process is efficient and smooth, effectively handling the water vapor mixture produced by the patient and providing a good environment for dental treatment. Simultaneously, the smooth rotation of the rotating seat 7 and the vertical pipe 9022 allows water and solid impurities discharged from the vertical pipe 9022 to exit through the channel in the center of the flange seat 601. The flange seat 601 is installed inside the casing 1, and a drain pipe interface is designed at the bottom of the flange seat 601. The flange seat 601 is directly connected to the casing, so the drain pipe will not rotate due to the rotation of the spittoon. The spittoon 5 is fixed to the internal support plate 2 with bolts. The flange seat and the entire spittoon are not fixedly connected to the casing in a non-removable manner, facilitating later maintenance and replacement. The rotation limit strip 701 and the sealing assembly 8 ensure the safety, stability, and convenience of the equipment.

[0048] Finally, it should be noted that the above are merely preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the utility model should be included within the protection scope of the utility model.
