Description

Technical Field

[0001] This utility model relates to the field of disinfection device technology, specifically to a disinfection device for oral surgery. Background Technology

[0002] Oral surgery encompasses various treatment procedures performed on the soft and hard tissues of the oral and maxillofacial region, including tooth extraction, dental implant surgery, and periodontal surgery. Because the oral cavity is a complex micro-ecological environment containing a large number of bacteria, fungi, and other microorganisms, and because the surgical area is directly connected to the digestive and respiratory tracts, the risk of postoperative infection is high. Therefore, preoperative cleaning and disinfection are crucial for ensuring surgical safety and reducing the incidence of infection. Preoperative treatment involves cleaning to remove food debris, plaque, and other impurities from the oral cavity, creating a clean environment for subsequent disinfection. Disinfection, on the other hand, uses chemical or physical methods to kill or inhibit pathogenic microorganisms in the oral cavity, reducing the possibility of microbial invasion of the wound during surgery. Currently, the most commonly used preoperative disinfection method in clinical practice is manual rinsing. This method requires medical staff to feed a measured amount of disinfectant solution into the patient's mouth one at a time, instructing the patient to rinse thoroughly to ensure complete contact between the disinfectant solution and the oral mucosa, tooth surfaces, and other areas before spitting out the disinfectant. To ensure disinfection effectiveness, this feeding, rinsing, and spitting process needs to be repeated multiple times to achieve comprehensive disinfection coverage of all areas of the oral cavity.

[0003] However, the existing technology has the following problems: In practice, existing mouthwash disinfection methods are cumbersome and inefficient because some patients are in a supine position during disinfection, and the procedures of feeding, rinsing, and spitting out the disinfectant require patients to frequently get up to spit out the disinfectant. Some patients with limited mobility may also experience discomfort due to frequent head and body movements during disinfection. Utility Model Content

[0004] This invention aims to solve the problem that existing gargling disinfection methods are cumbersome and inefficient in practice because some patients are in a supine position during disinfection, and the operation of feeding, gargling, and spitting out the disinfectant requires the patient to get up frequently to spit out the disinfectant. In addition, some patients with limited mobility may experience discomfort due to frequent head and body movements during disinfection.

[0005] In view of this, the present invention provides a sterilization device for oral surgery.

[0006] In this technical solution, a disinfection device for oral surgery includes: a housing, on which a mounting bracket is mounted, and a clean liquid bottle and a waste liquid bottle are connected to the mounting bracket via clamps, with a piston slidably connected inside the clean liquid bottle; a rinsing assembly is provided on the housing, the rinsing assembly including a clean liquid tube and a waste liquid tube, two connectors are connected to the bottom of the housing, and the bottom ends of the clean liquid tube and the waste liquid tube are respectively connected to the two connectors; a first perforated plate is mounted on the top of the housing, a second perforated plate is rotatably connected to the top surface of the first perforated plate, a diverter tube is connected to the second perforated plate, and a rinsing head is connected to the end of the diverter tube away from the second perforated plate; a first flow channel and a second flow channel are provided inside the rinsing head and the diverter tube, and the first flow channel and the second flow channel cooperate to realize the circulation of disinfectant water in the oral cavity; a driving mechanism is provided on the mounting bracket for driving the piston to move; and an air bubble assembly is provided inside the housing for forming air bubbles inside the clean liquid tube.

[0007] Furthermore, the purified liquid bottle and the waste liquid bottle are respectively connected to the bottom of two connectors.

The rinsing head is adapted to the outer shape of the teeth and is provided with multiple through holes.

[0008] Furthermore, the first perforated plate can rotate at the bottom of the second perforated plate. After rotating 180 degrees, the first perforated plate can connect the clean liquid bottle, the clean liquid tube, the first flow hole of the first perforated plate, the second flow hole of the second perforated plate, the rinsing head, and the second flow channel of the diverter tube. The waste liquid bottle, the waste liquid tube, the second flow hole of the first perforated plate, the first flow hole of the second perforated plate, the rinsing head, and the first flow channel of the diverter tube can also be connected.

[0009] Furthermore, two abutment rods are slidably connected to the inner wall of the second perforated plate along the axial direction of the second perforated plate. A spring is provided between the abutment rod and the inner wall of the second perforated plate. A hemisphere is connected to the bottom of the abutment rod. Two hemispherical grooves are opened on the top surface of the first perforated plate. The two hemispheres are respectively embedded in the two hemispherical grooves of the first perforated plate.

[0010] Furthermore, valve plates are hinged to the inner walls of the first and second flow channels of the diversion pipe, and a reset leaf spring is provided between the valve plate and the inner wall of the diversion pipe. Wedges are slidably connected to the outer walls on both sides of the diversion pipe. Each wedge has an inclined surface. The tops of the two abutment rods slide in contact with the inclined surfaces of the two wedges, and the two wedges slide in contact with the two valve plates. When the abutment rods move upward, they can use the inclined surfaces to drive the wedges to move closer to the inner wall of the diversion pipe. When the wedges move closer to the inner wall of the diversion pipe, they can drive the valve plates to flip down. After the two valve plates flip down, they can close the first and second flow channels.

[0011] Furthermore, the driving mechanism includes a lead screw, which is rotatably mounted on a mounting bracket. A stopper rod is slidably connected through the bottom of the purified liquid bottle. One end of the stopper rod is connected to a piston, and the other end of the stopper rod is connected to a nut block. The nut block is threadedly connected to the lead screw. A crank is installed at the bottom of the lead screw, and a handle is installed on the mounting bracket. When the lead screw rotates, it can drive the stopper rod to perform telescopic movement through the nut block.

[0012] Furthermore, the bubble assembly includes a gas box, which is mounted on a distribution pipe. Multiple bubble tubes are connected to the gas box, all located within the distribution pipe. Each bubble tube has multiple micro-holes and a one-way valve plate inside. A sliding shaft is slidably connected through the housing, with a pressure block and a smooth plate connected to its two ends respectively. The outer wall of the pressure block is slidably connected to the inner wall of the gas box. A cam is connected to the top of the lead screw. A spring is provided between the sliding shaft and the inner wall of the housing, and a spring is provided between the pressure block and the inner wall of the gas box. The smooth plate is located outside the housing. When the cam rotates, it contacts the smooth plate and drives the smooth plate to move closer to the gas box. A gas supply pipe is provided on the gas box.

[0013] Furthermore, the bubble assembly also includes a rotating shaft, which is rotatably mounted on the purified liquid tube. Multiple thin rods are connected to the outer wall of the rotating shaft, and the thin rods are located inside the purified liquid tube. A grooved shaft is connected to one end of the rotating shaft near the pressure block. A sliding tongue is connected to the pressure block. An annular inclined groove is formed on the grooved shaft. The sliding tongue is slidably connected to the annular inclined groove of the grooved shaft. When the sliding tongue moves back and forth, it can drive the rotating shaft to rotate back and forth through the grooved shaft.

[0014] Furthermore, a heating assembly is provided inside the housing. The heating assembly includes a controller, which is mounted on the housing. A heating sleeve is connected to the controller and fits onto the outer wall of the purified liquid tube. A spring wire is connected to the controller, and a plug is connected to the end of the spring wire. The spring wire is located inside the housing, and the plug is located outside the housing.

[0015] Compared with existing technologies, the oral surgery disinfection device of this invention has the following advantages: 1. This oral surgery disinfection device, through the design of the rinsing component, allows the disinfectant to circulate in the patient's oral cavity. This ensures that new disinfectant continuously enters the patient's oral cavity while waste liquid is continuously discharged, improving the efficiency of oral cleaning and disinfection. The patient does not need to move their head or body during the disinfection process, making the process more comfortable. Furthermore, through the rotation of the first and second perforated plates, the disinfectant can circulate in reverse within the patient's oral cavity. This reverse circulation ensures that any blind spots in the original rinsing and disinfection process are thoroughly rinsed and disinfected, thereby optimizing the disinfection effect.

[0016] 2. This oral surgery disinfection device, through the setting of the bubble assembly, allows the gas in the air box to enter the disinfectant water in the diversion tube through the micro-pores on multiple bubble tubes, forming a large number of microbubbles. The microbubbles mixed in with the disinfectant water can increase the contact area between the disinfectant water and oral tissues. At the same time, the micro-impact force generated when the bubbles burst can enhance the cleaning effect on hard-to-reach areas such as tooth gaps and gingival sulci, thereby improving disinfection efficiency and effect. Meanwhile, multiple thin rods rotate synchronously in the clean liquid tube to create a stirring effect. The stirring action of the thin rods can evenly disperse the microbubbles in the disinfectant water, thus ensuring the enhanced disinfection effect of the bubbles.

[0017] 3. This oral surgery disinfection device, through the setting of the heating component, can help improve patient comfort when disinfecting patients' mouths in winter, since some patients' mouths are more sensitive to low temperatures. The heating component heats the disinfectant before it is delivered to the patient's mouth. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] One embodiment of this utility model is as follows: Please see Figure 1 - Figure 7A disinfection device for oral surgery includes: a housing 1, a mounting bracket 2 mounted on the housing 1, a clean liquid bottle 3 and a waste liquid bottle 4 connected to the mounting bracket 2 via clamps, a piston 52 slidably connected inside the clean liquid bottle 3, a rinsing assembly 5 on the housing 1, the rinsing assembly 5 including a clean liquid tube 54 and a waste liquid tube 55, two connectors 53 connected to the bottom of the housing 1, the bottom ends of the clean liquid tube 54 and the waste liquid tube 55 respectively connected to the two connectors 53, a first perforated plate 56 mounted on the top of the housing 1, a second perforated plate 57 rotatably connected to the top surface of the first perforated plate 56, a diverter pipe 58 connected to the second perforated plate 57, a rinsing head 59 connected to the end of the diverter pipe 58 away from the second perforated plate 57, and a first flow channel and a second flow channel provided inside the rinsing head 59 and the diverter pipe 58. The first and second flow channels work together to achieve the circulation of disinfectant in the oral cavity. The purified liquid bottle 3 and the waste liquid bottle 4 are respectively connected to the bottom of two connectors 53. The first perforated plate 56 and the second perforated plate 57 are respectively provided with first and second flow holes. The first flow channels of the purified liquid bottle 3, purified liquid tube 54, the first flow hole of the first perforated plate 56, the first flow hole of the second perforated plate 57, the rinsing head 59, and the diverter pipe 58 are connected. The second flow holes of the waste liquid bottle 4, waste liquid tube 55, first perforated plate 56, the second flow hole of the second perforated plate 57, the rinsing head 59, and the diverter pipe 58 are connected. The rinsing head 59 is adapted to the shape of the outer side of the teeth and has multiple through holes. The purified liquid bottle 3 is provided with a filling port. The mounting bracket 2 fixes the purified liquid bottle 3 and the waste liquid bottle 4 with clamps. The detachable and adjustable clamps of the liquid bottle 4 ensure the secure fixing of the purified liquid bottle 3 and the waste liquid bottle 4, while also facilitating subsequent refilling of the purified liquid bottle 3 and cleaning of the waste liquid bottle 4. The connector 53 acts as a transfer connection, creating a sealed connection between the purified liquid bottle 3, the waste liquid bottle 4, the purified liquid tube 54, and the waste liquid tube 55. When the piston 52 inside the purified liquid bottle 3 slides upward, it compresses the disinfectant solution inside the purified liquid bottle 3, causing the disinfectant solution to flow sequentially through the purified liquid tube 54, the first flow hole of the first perforated plate 56, the first flow hole of the second perforated plate 57, and the first flow channel of the diversion tube 58, finally flowing out from the through hole near the first flow channel of the rinsing head 59. The patient should hold the rinsing head 59 in their mouth beforehand, ensuring it fits against the inner cheek and outer teeth for rinsing. After the disinfectant flows out of the first channel of the shampoo head 59, it enters the patient's mouth to clean and disinfect it. When the disinfectant in the patient's mouth is saturated, the excess disinfectant (hereinafter referred to as waste liquid) enters the second channel through the through hole at the second channel of the rinsing head 59. Subsequently, the waste liquid passes through the second channel of the diversion pipe 58, the second orifice of the second perforated plate 57, the second orifice of the first perforated plate 56, and the waste liquid pipe 55 in sequence, and finally enters the waste liquid bottle 4 for collection. This allows the disinfectant to circulate in the patient's mouth, so that new disinfectant continuously enters the patient's mouth while waste liquid is continuously discharged, improving the efficiency of oral cleaning and disinfection. The patient does not need to move their head or body during the disinfection process, making the disinfection process more comfortable.

[0026] Furthermore, the mounting bracket 2 is equipped with a drive mechanism 6 for moving the piston 52. The drive mechanism 6 includes a lead screw 61, which is rotatably mounted on the mounting bracket 2. A stopper rod 51 is slidably connected through the bottom of the purified liquid bottle 3. One end of the stopper rod 51 is connected to the piston 52, and the other end of the stopper rod 51 is connected to a nut block 63. The nut block 63 is threadedly connected to the lead screw 61. A crank 62 is installed at the bottom of the lead screw 61, and a handle 64 is installed on the mounting bracket 2. When the lead screw 61 rotates, it can drive the stopper rod 51 to perform telescopic movement through the nut block 63. Because the nut block 63 is fixedly connected to the stopper rod 51, its rotational freedom is restricted. When the lead screw is rotated by the crank 62... At position 61, the rotational motion of the lead screw 61 is converted into the linear motion of the nut block 63 along the axis of the lead screw 61. When the nut block 63 moves, it drives the piston 52 to move synchronously through the stopper rod 51. The forward crank 62 can drive the stopper rod 51 to move upward, and the reverse crank 62 can drive the stopper rod 51 to move downward. By controlling the number of rotations and speed of the crank 62, medical staff can accurately adjust the displacement and speed of the piston 52 pushed by the stopper rod 51, thereby achieving controllable adjustment of the disinfectant output and output pressure. The handle 64 provides a stable gripping point for medical staff, making it easy to keep the housing 1 stable when turning the crank 62, improving the convenience and safety of operation.

[0027] Furthermore, the first perforated plate 56 can rotate at the bottom of the second perforated plate 57. After rotating 180 degrees, the first perforated plate 56 can connect the clean liquid bottle 3, the clean liquid tube 54, the first flow orifice of the first perforated plate 56, the second flow orifice of the second perforated plate 57, the rinsing head 59, and the second flow channel of the diverter tube 58. The waste liquid bottle 4, the waste liquid tube 55, the second flow orifice of the first perforated plate 56, the first flow orifice of the second perforated plate 57, the rinsing head 59, and the first flow channel of the diverter tube 58 can also be connected. After the patient's oral cavity has been disinfected for a period of time, medical staff can rotate the entire housing 1, causing the housing 1 to rotate the first perforated plate 56 180 degrees. During this process, the first flow orifice and the second flow orifice between the first perforated plate 56 and the second perforated plate 57 are connected. The flow path is misaligned, and then the first flow hole of the first perforated plate 56 is connected to the second flow hole of the second perforated plate 57, and the second flow hole of the first perforated plate 56 is connected to the first flow hole of the second perforated plate 57. In this state, the functions of the first flow channel and the second flow channel in the diversion tube 58 are replaced, so that the first flow channel becomes the discharge channel for waste liquid and the second flow channel becomes the inlet channel for liquid. For example, the previous rinsing head 59 discharged liquid from the left side and discharged liquid from the right side in the patient's mouth. After the rotation, it becomes that the liquid discharges liquid from the right side and discharged liquid from the left side in the patient's mouth, so that the disinfectant can circulate in reverse in the patient's mouth. This allows the blind spots that existed in the original rinsing and disinfection process to be fully rinsed and disinfected through reverse circulation, thereby optimizing the disinfection effect.

[0028] In addition, two abutment rods 510 are slidably connected to the inner wall of the second perforated plate 57 along its axial direction. A spring is provided between the abutment rods 510 and the inner wall of the second perforated plate 57. A hemisphere 511 is connected to the bottom of the abutment rod 510. Two hemispherical grooves are opened on the top surface of the first perforated plate 56, and the two hemispheres 511 are respectively embedded in the two hemispherical grooves of the first perforated plate 56. The spring always applies downward pressure to the abutment rods 510, keeping the hemispheres 511 at the bottom of the abutment rods 510 embedded in the hemispherical grooves on the top surface of the first perforated plate 56. The positioning and fixation of the first perforated plate 56 after rotation is achieved through the contact of the hemispherical surfaces, preventing over-sterilization. During the process, vibration causes the first or second orifice plate 56 orifice plate 57 to rotate on its own. When the first orifice plate 56 is rotated, the rotational force applied by the operator can cause the hemisphere 511 to overcome the spring pressure and dislodge from the hemisphere groove. The abutment rod 510 moves up along the inner wall of the second orifice plate 57, and the hemisphere 511 slides along the top surface of the first orifice plate 56 until it rotates to the next hemisphere groove position. The spring pushes the hemisphere 511 at the bottom of the abutment rod 510 to embed into the groove to complete the positioning. When the hemisphere 511 is embedded into the hemisphere groove, it will produce a slight vibration, so that medical staff can feel a clear rotation positioning feedback during the rotation of the first orifice plate 56.

[0029] It is worth noting that valve plates 513 are hinged to the inner walls of the first and second flow channels of the diversion pipe 58, respectively. A reset leaf spring is provided between the valve plate 513 and the inner wall of the diversion pipe 58. Wedges 512 are slidably connected through the outer walls on both sides of the diversion pipe 58. The wedges 512 have inclined surfaces. The tops of the two abutment rods 510 slide in contact with the inclined surfaces of the two wedges 512, respectively. The two wedges 512 slide in contact with the two valve plates 513, respectively. When the abutment rods 510 move upward, they can... The inclined plane can be used to move the wedge 512 towards the inner wall of the diversion pipe 58. When the wedge 512 moves towards the inner wall of the diversion pipe 58, it can cause the valve plate 513 to flip down. After the two valve plates 513 flip down, they can close the first flow channel and the second flow channel. The reset leaf spring always applies a spring force to the valve plate 513 towards the inner wall of the diversion pipe 58, so that the valve plate 513 is tightly pressed against the inner wall of the diversion pipe 58 and kept in the open state. When the first orifice plate 56 is rotated, the two abutment rods 510 As the hemisphere 511 moves upward due to its counterforce, the top of the contact rod 510 slides along the inclined surface of the wedge 512. The guiding effect of the inclined surface converts the axial force of the contact rod 510 into the radial force of the wedge 512, pushing the wedge 512 towards the inner wall of the diversion pipe 58. After moving, the wedge 512 contacts the valve plate 513 and applies pressure, causing the valve plate 513 to overcome the spring force of the return leaf spring and flip downward around the hinge point until the valve plate 513 is tightly fitted against the inner wall of the flow channel, thus realizing the first flow channel. The synchronous closure of the first and second flow channels closes the first and second flow channels in the diversion pipe 58 during the rotation of the first orifice plate 56, preventing cross-flow between the first and second flow holes when the first orifice plate 56 rotates and the second orifice plate 57 is rotated. When the first orifice plate 56 is rotated to the position, the abutment rod 510 is reset under the action of the spring, the reset leaf spring drives the valve plate 513 to reset, the valve plate 513 pushes the wedge block 512 back, and the diversion pipe 58 is restored to unobstructed flow.

[0030] Based on the above embodiments, another embodiment of this utility model is as follows: Please see Figure 2 , Figure 9 - Figure 11The housing 1 contains a bubble assembly 8 for forming bubbles within the purified liquid tube 54. The bubble assembly 8 includes a gas box 81, which is mounted on a diversion tube 58. Multiple bubble tubes 83 are connected to the gas box 81 and are located within the diversion tube 58. Each bubble tube 83 has multiple micro-pores and a one-way valve plate inside. A sliding shaft 84 is slidably connected through the housing 1. A pressure block 82 and a smooth plate 85 are connected to both ends of the sliding shaft 84, respectively. The outer wall of the pressure block 82 slides against the inner wall of the gas box 81. The screw 61 is connected to a cam 86 at its top. A spring is provided between the sliding shaft 84 and the inner wall of the housing 1, and a spring is provided between the pressure block 82 and the inner wall of the air box 81. The smooth plate 85 is located outside the housing 1. When the cam 86 rotates, it contacts the smooth plate 85 and drives the smooth plate 85 to move closer to the air box 81. The air box 81 is provided with an air supply pipe. When the screw 61 rotates, it drives the cam 86 to rotate synchronously. The eccentric structure of the cam 86 causes it to periodically contact and press the smooth plate 85 during rotation, pushing the smooth plate 85 to move the sliding shaft 84. When shaft 84 moves towards air box 81, it drives pressure block 82 to slide inside air box 81. Pressure block 82 compresses the internal space of air box 81, causing gas inside air box 81 to enter the disinfectant water in diversion pipe 58 through micro-pores on multiple bubble tubes 83, forming a large number of micro-bubbles. The one-way valve plate in bubble tube 83 only allows gas to flow from air box 81 to diversion pipe 58, preventing disinfectant water from flowing back into air box 81 and ensuring unobstructed air passage. When cam 86 rotates to the non-extrusion plate 85... When in position, the springs between the sliding shaft 84 and the housing 1, and between the pressure block 82 and the air box 81 work together to push the sliding shaft 84 and the pressure block 82 back to their original positions through elastic force. A negative pressure is formed inside the air box 81 and air is automatically drawn in through the air supply pipe to prepare for the next air supply. The tiny bubbles mixed in with the disinfectant can increase the contact area between the disinfectant and the oral tissue. At the same time, the tiny impact force generated when the bubbles burst can enhance the cleaning effect on dead corners such as tooth gaps and gingival sulci, thereby improving the disinfection efficiency and disinfection effect.

[0031] It is worth mentioning that the bubble assembly 8 also includes a rotating shaft 87, which is rotatably mounted on the purified liquid tube 54. Multiple thin rods 88 are connected to the outer wall of the rotating shaft 87, and these rods 88 are located inside the purified liquid tube 54. A grooved shaft 89 is connected to one end of the rotating shaft 87 near the pressure block 82. A sliding tongue 810 is connected to the pressure block 82. An annular inclined groove is formed on the grooved shaft 89, and the sliding tongue 810 is slidably connected to the annular inclined groove of the grooved shaft 89. When the sliding tongue 810 reciprocates, it can drive the rotating shaft 87 to reciprocate through the grooved shaft 89. During the reciprocating movement of the pressure block 82, the sliding tongue on it is simultaneously driven. 810 makes a linear reciprocating motion. Since the sliding tongue 810 is embedded in the annular inclined groove of the groove shaft 89, and the annular inclined groove surrounds the groove shaft 89 in a spiral trajectory, the linear motion of the sliding tongue 810 is converted into the rotational motion of the groove shaft 89 through the guiding effect of the annular inclined groove. This, in turn, drives the rotating shaft 87, which is fixedly connected to the groove shaft 89, to rotate back and forth. When the rotating shaft 87 rotates, multiple thin rods 88 on its outer wall rotate synchronously in the clean liquid tube 54, forming a stirring effect. The stirring effect of the thin rods 88 can make the micro bubbles evenly dispersed in the disinfectant water, thereby ensuring the enhanced disinfection effect of the bubbles.

[0032] Based on the above embodiments, another embodiment of this utility model is as follows: Please see Figure 2 , Figure 8 The housing 1 contains a heating component 7, which includes a controller 71 mounted on the housing 1. A heating sleeve 72 is connected to the controller 71 and fits onto the outer wall of the purified liquid tube 54. A spring wire is connected to the controller 71, with a plug at the end of the spring wire. The spring wire is located inside the housing 1, and the plug is located outside the housing 1. The controller 71 integrates a temperature monitoring module and a power regulation chip, which can monitor the temperature of the heating sleeve 72 and the disinfectant in the purified liquid tube 54 in real time. When the temperature is lower than the preset value, the heating power is automatically increased. Once the set temperature is reached, the temperature is maintained at a constant level to prevent burns to oral tissues due to excessive heat. The heating sleeve 72 is made of flexible electric heating material and can achieve all-around wrapping after being tightly fitted onto the outer wall of the purified liquid tube 54. The heating element efficiently converts electrical energy into heat energy and transfers it to the inside of the sterile solution tube 54, ensuring uniform heating of the sterile solution and avoiding localized overheating or insufficient heating. The spring-loaded wire is a key component connecting the controller 71 to the external power supply. Its retractable feature allows operators to easily pull the plug out of the housing 1 to connect to the power supply, and it can automatically retract back into the housing 1 when not in use, preventing the wire from becoming tangled and affecting the surgical procedure, while also reducing the risk of the wire being damaged by external force. After the plug is connected to the external power supply, it provides a stable power input to the heating element 7, ensuring continuous and reliable heating. In winter, since some patients' oral cavity is more sensitive to low temperatures, heating the sterile solution with the heating element 7 before it is introduced into the patient's oral cavity helps to improve patient comfort.

[0033] Based on the above embodiments, another embodiment of this utility model is as follows: The waste liquid bottle 4 is equipped with a negative pressure suction device. When some patients' oral cavity has poor tolerance to water pressure, the negative pressure suction device in the waste liquid bottle 4 can be turned on. This allows the liquid in the clean liquid bottle 3 to be continuously injected while the negative pressure suction device in the waste liquid bottle 4 assists in the discharge of waste liquid, thereby relieving the pressure inside the patient's oral cavity and preventing the patient from not properly covering the rinsing head 59 during disinfection due to poor oral cavity tolerance, which would cause some waste liquid to overflow from the corner of the patient's mouth.

[0034] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
