Description

Technical Field

[0001] The present invention belongs to the technical field of oral irrigation, and particularly relates to an oral low-temperature irrigator for reducing oral mucositis.

[0002] This case is a divisional application of the application with the application number 202311311610.9 and the invention creation name of "Oral Low-temperature Irrigator for Reducing Oral Mucositis during Chemotherapy". The filing date of the original application is October 11, 2023. Background Art

[0003] Oral mucositis is one of the most common complications during the treatment of cancer patients with anti-tumor drugs, radiotherapy, and hematopoietic stem cell transplantation. The main manifestations are inflammatory changes of varying degrees in the oral mucosa, dryness, sensitivity, pain, ulcers and other discomfort symptoms. Applying routine oral care can prevent oral mucositis caused by anti-tumor treatment. However, due to the complex procedures and the need for long-term adherence, it increases the workload of nurses, and the patient management process is more cumbersome with low compliance, often resulting in poor prevention effects. In addition, before, during, and after the rapid infusion of high-dose chemotherapy drugs with a short half-life, patients can hold ice cubes or ice water in their mouths to prevent the occurrence of oral mucositis, but the curative effect is not very exact, and the self-experience of patients is not good.

[0004] The invention patent with the authorization number US10478267B2 relates to an oral irrigator, which has an independent high-pressure water system and a low-pressure gargle system, and can deliver two different liquids to a pick head or other accessories. The water system and the gargle system are combined in a handle. The pick head is connected to the handle. The water system has a blocking valve on the handle, and the gargle system has a hand pump on the handle. The manual pump is located next to the valve button that closes the blocking valve. When the manual pump is pressed, it holds the valve button of the blocking valve and cuts off the source of high-pressure water to the nozzle. The pressure inside the pick head drops, so that the hand pump can introduce the gargle liquid into the pick head. When the hand pump is released, the blocking valve opens and the high-pressure water returns to the pick head.

[0005] Most of the existing oral irrigators are positioned for home use. For example, the invention application with the publication number US20190358006A1 does not have medical functions and has low medical feasibility. The medical oral irrigators are not yet mature, and the existing oral irrigators for auxiliary medical use often have deficiencies such as complex operation and poor patient experience. Summary of the Invention

[0006] The purpose of the present invention is to provide an oral low-temperature irrigator for reducing oral mucositis with a simple structure and easy operation, which can realize the cooling treatment of the patient's oral cavity and improve the comfort of use.

[0007] The technical solution adopted by the present invention to achieve the above purpose is as follows: An oral hypothermia irrigator for reducing oral mucositis, including a first base body. When in use, the first base body extends into the patient's oral cavity, so the first base body is set in a shape adapted to the human oral cavity; inside the first base body, there are a cooling pipe group, a spray pipe group and an overflow channel; The cooling pipe group is arranged in the middle of the first base body, including a first inflow pipe for liquid inlet and a first return pipe for liquid discharge, which is used to provide flowing cooling liquid inside the first base body; The spray pipe group is arranged on the outer edge of the first base body. The spray pipe group cooperates with the spraying component to spray the rinsing liquid into the oral cavity; the spraying component is arranged on the outer surface of the first base body; the spray pipe group includes a second inflow pipe for liquid inlet and a second return pipe for liquid discharge. The second inflow pipe and the second return pipe are respectively arranged on the left and right sides of the first base body; One end of the overflow channel extends to the outer surface of the first base body, so as to facilitate the connection between the overflow channel and the patient's oral cavity, and is used to collect and discharge the rinsing liquid in the oral cavity; a valve body is arranged in the overflow channel to close or connect the overflow channel.

[0008] The first base body is in a structure similar to a dental appliance that can be inserted into the mouth. Through the cooperation of the spray pipe group and the spraying component, multiple spraying outlets can be set for the spraying component, and the rinsing liquid can be sprayed into the patient's oral cavity from multiple angles on the outer edge of the first base body, so as to clean the patient's oral cavity comprehensively and avoid cleaning dead corners.

[0009] The setting of the cooling pipe group provides cooling liquid with a relatively low temperature inside the first base body through the first inflow pipe. After heat exchange with the inside of the oral cavity, the cooling liquid is then discharged through the first return pipe, so as to take away the heat inside the patient's oral cavity and achieve the effect of rapid cooling. In addition, the cooling pipe group can also be provided with openings, so that it can be connected to the oral cavity similar to the spray pipe group. In this way, the cooling liquid inside the first inflow pipe can enter the patient's oral cavity through the first base body and then be discharged through the first return pipe, thereby improving the cooling efficiency.

[0010] The rinsing liquid for rinsing the oral cavity and the cooling liquid discharged from the cooling pipe group into the oral cavity can both be discharged from the oral cavity through the overflow channel. In order to ensure the liquid discharge effect, the discharge ends of the cooling pipe group, that is, the first return pipe and the discharge end of the overflow channel, can be connected to a micro pump body.

[0011] Adopting the above technical solution, the cooling pipe group and the spray pipe group are independently arranged, which can carry out oral cavity cooling treatment while cleaning the oral cavity, and can also carry out oral cavity cleaning or oral cavity cooling separately. Moreover, the cooling liquid entering the patient's oral cavity can be discharged through the overflow channel or through the first return pipe in the cooling pipe group. The rinsing liquid and the cooling liquid in the oral cavity can also be spit out manually after taking out the first base body. The usage method is diversified, which can meet different usage scenarios and different usage requirements, and has strong adaptability.

[0012] In addition, the coolant flows through the first inlet pipe and the first return pipe in the cooling pipe group to perform basic cooling treatment on the oral cavity, only taking away the heat in the oral cavity. By flowing the cooling pipe group inside the first base, the heat in the oral cavity is absorbed and taken out. In this process, the flow channel can be in an open state, which facilitates the discharge of the gas in the oral cavity of the person, thereby improving the comfort of the patient.

[0013] According to an embodiment of the present invention, the first base is of a U-shaped structure, and a tongue-shaped auxiliary component is arranged inside the first base; an auxiliary channel is arranged inside the auxiliary component, and the auxiliary channel is communicated with the flow channel.

[0014] The auxiliary component is provided with a plurality of through holes, all of the plurality of through holes are communicated with the auxiliary channel, at least one through hole is provided with an extension strip, the extension strip extends outward from the outer surface of the auxiliary base, and the extension strip is provided with a notch.

[0015] Furthermore, a valve body is arranged at the connection end of the auxiliary channel and the flow channel.

[0016] Furthermore, the cooling pipe group extends from the inside of the first base to the inside of the auxiliary component. In this way, by laying the cooling pipe group inside the auxiliary component, the temperature reduction treatment of the tongue surface area can be realized, so that the temperature inside the oral cavity can quickly reach equilibrium, and the temperature reduction effect is improved.

[0017] Thus, by arranging the auxiliary component, the contact area with the inside of the patient's oral cavity during the use of the irrigator can be enlarged, and it can be prevented from shifting and misaligning due to the flow of the internal liquid and the spraying of the flushing liquid, thereby improving the wearing comfort.

[0018] As required, a plurality of openings of the auxiliary channel can be respectively arranged at positions such as the end, bottom surface and top surface of the auxiliary component. In this way, the flushing liquid and / or coolant inside the oral cavity can be collected from different directions to the flow channel, which is convenient for the discharge of the flushing liquid and / or coolant.

[0019] An extension strip is arranged at the opening position of the auxiliary channel, especially at the outer edge of the opening arranged on the bottom surface of the auxiliary component. Because the bottom surface of the auxiliary component is attached to the patient's tongue, the arrangement of the extension strip can prevent the auxiliary component from being overly attached to the tongue, prevent the two from sticking, and can avoid excessive cooling of the tongue surface, etc. The arrangement of the extension strip forms a spaced space between the tongue and the auxiliary component. In this way, the flushing liquid sprayed by the spraying component into the oral cavity can flow on the tongue surface, so as to ensure the flushing of the tongue surface, prevent the appearance of cleaning dead corners, and the flow space of the flushing liquid is enlarged, and the flushing effect is improved.

[0020] According to an embodiment of the present invention, the auxiliary component includes two symmetrically arranged auxiliary plates, and a connecting member is disposed between the two auxiliary plates. The connecting member includes a rotating rod and an elastic member. The elastic member is disposed between the two rotating rods, and the ends of the two rotating rods away from the elastic member are respectively connected to the two auxiliary plates.

[0021] Further, the cooling pipe group is adaptively laid inside the two auxiliary plates, and auxiliary channels are configured in both of the two auxiliary plates for communicating with the flow-through channels.

[0022] Thus, the tongue-shaped auxiliary component is longitudinally divided into two symmetric auxiliary plates, and through the cooperation of the connecting member, the auxiliary plates can move and adjust positions inside the first base body, so as to improve the wearing comfort of the rinser as much as possible. Moreover, the heat exchange range of the cooling pipe group for the oral cavity can be expanded by the movable auxiliary plates.

[0023] In addition, by dividing the auxiliary component into two symmetric parts, with a certain distance between the two auxiliary plates and connected by an elastic member and a rotating rod in the middle, when spraying, the gap between the auxiliary plates can be enlarged by the movement of the tongue, which helps the flow and discharge of the rinsing liquid. By designing the elastic member and the auxiliary plates, etc., when the gap between the two auxiliary plates is enlarged, it is helpful for lumps or other dirt in the oral cavity to enter the auxiliary channels, so as to improve the cleaning effect.

[0024] According to an embodiment of the present invention, the spraying component includes a corresponding first spraying plate and a second spraying plate, and a drainage channel is provided between the two, and the drainage channel is communicated with the spraying pipe group.

[0025] Further, a spraying base is arranged between the first spraying plate and the second spraying plate. A spraying channel is arranged in the middle of the spraying base, and one end of the spraying channel is communicated with the drainage channel.

[0026] The spraying component is arranged corresponding to positions such as teeth and gums in the oral cavity, which helps to spray and cool each area of the oral cavity, and can also clean and cool the tongue area during the process of discharging the rinsing liquid. A drainage channel capable of allowing liquid to flow through is formed between the first spraying plate and the second spraying plate. The spraying base is arranged inside the drainage channel, and there is a gap between the top surface of the spraying base and the first spraying plate, so as to realize the communication between the spraying channel and the drainage channel.

[0027] After the flushing liquid enters the drainage channel, the space between the first flushing plate and the second flushing plate will expand, enabling the contact state between the first substrate and the oral cavity to change. For example, this expansion effect causes the contact area between the first flushing plate, the second flushing plate of the spraying assembly and the gums and teeth in the oral cavity to change, which can avoid the discomfort caused by the continuous single contact state between the first substrate and the interior of the oral cavity of the patient; and the adjustment of the contact state enables the contact part to be cleaned by the flushing liquid, thereby avoiding the growth of bacteria in the surrounding area caused by continuous contact; in addition, after expansion, the contact area between the first substrate and the inner wall of the oral cavity is reduced, the flushing range of the liquid after flushing is expanded, the flushing dead angle is reduced, and it helps to discharge dirt and bacteria.

[0028] Further, the outer edge of the side of the flushing base near the first flushing plate is configured with an inclined surface, and along the radial direction of the flushing base, the inclined surface gradually extends from the inside to the outside in the direction close to the second flushing plate.

[0029] Further, the spraying channel is of a hourglass structure, and the outlet end of the spraying channel is arranged on the surface of the second flushing plate; the spraying channel includes a first tapered hole, a connecting channel and a second tapered hole connected in sequence. One end of the first tapered hole far from the second tapered hole is communicated with the drainage channel, and one end of the second tapered hole far from the first tapered hole is provided with a spraying outlet on the surface of the second flushing plate.

[0030] Further, the outlet end of the spraying channel is configured with a guiding convex ring, the guiding convex ring is arranged around the outlet end of the spraying channel, and the guiding convex ring is configured with a turbine-shaped groove.

[0031] The setting of the flushing base helps to increase the flow rate of the flushing liquid when it enters the spraying channel; the settings of the first tapered hole and the second tapered hole cause the flushing liquid entering the spraying channel to generate a swirling flow and be discharged in a swirling manner, which further increases the flow rate of the flushing liquid and changes its flow direction, improving the flushing effect on the oral cavity and expanding the flushing range. The guiding convex ring is provided with a turbine-shaped groove, which also helps to guide the flushing liquid to flow in different directions and further expand the flushing range. In addition, the setting of the guiding convex ring avoids the continuous contact between the first flushing plate, the second flushing plate and the teeth and gums in the oral cavity, as well as the problem of too large contact area, improving the comfort level.

[0032] According to an embodiment of the present invention, the rear end of the first substrate is connected with a second substrate, one end of the second substrate close to the first substrate is configured with a baffle, and one side of the baffle facing the first substrate is configured with a gasket.

[0033] The baffle has a certain bending arc, and the baffle is used to assist in closing the patient's mouth during use. In this way, on the one hand, it helps to fix the first substrate inside the patient's oral cavity, and on the other hand, it can also prevent the flushing liquid from dripping from the patient's mouth corners during the flushing process, improving the comfort level of the patient. The cooling pipeline and the flushing pipeline both pass through the second substrate and are connected to the external pipeline.

[0034] According to an embodiment of the present invention, the cooling pipe group is connected to the control box through the first connecting pipe body, and the control box is used to supply coolant into the cooling pipe group. The spraying pipe group is connected to the control box through the second connecting pipe body, and the control box supplies flushing liquid into the spraying pipe group. Two substrates are arranged in the control box, and there is a gap between the two substrates. A plurality of heat dissipation fins arranged side by side are provided above the two substrates. The first connecting pipe body is matched with the heat dissipation fins, and a heat dissipation fan is provided on the side of the plurality of heat dissipation fins.

[0035] In this way, there is a gap between the two arranged substrates. The direction of the exhaust air of the heat dissipation fan is not limited to one side of the heat dissipation fins, and heat exchange can also be carried out by discharging air flow to the bottom. In this way, the heat exchange area is increased, and thus the heat concentration at a single position of the control box is avoided, effectively improving the balance of the ambient temperature. In addition, the expansion of the heat exchange area can reduce the air flow discharge flow rate at a single position, and thus reduce the wind noise.

[0036] Compared with the prior art, the present invention has the following beneficial effects: 1. The cooling pipe group and the spraying pipe group are independently arranged, and the usage modes are diversified, which can meet different usage scenarios and different usage requirements, and have strong adaptability; 2. The first base body is matched with the auxiliary component, which can prevent the first base body from shifting and misaligning during use, improving the comfort; and it can also prevent the occurrence of cleaning dead corners, expand the flow space of the flushing liquid, and improve the flushing effect; 3. The matching structure of the auxiliary plate and the connecting piece can improve the wearing comfort of the rinser, strengthen the protection of the teeth and the oral inner wall skin, expand the heat exchange range of the cooling pipe group in the oral cavity, and is also helpful for the flow and discharge of the flushing liquid; 4. A spraying base is arranged between the first spraying plate and the second spraying plate, which helps to adjust the flow rate and flow direction of the flushing liquid and improve the flushing effect.

[0037] Therefore, the present invention is an oral low-temperature rinser for reducing oral mucositis with a simple structure and easy operation, which can realize the cooling treatment of the patient's oral cavity and improve the use comfort. Brief Description of the Drawings

[0040] The technical solutions of the present invention will be further described in detail below in conjunction with the specific implementation manners and the drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] Embodiment 1 Figures 1 to 7 Schematically shows an oral low-temperature rinser for reducing oral mucositis according to an embodiment of the present invention. As Figure 1 , Figure 2 and Figure 4 shown, the device includes a U-shaped first base body 10, which extends into the patient's oral cavity during use, so the first base body 10 is designed to be in a shape similar to a dental appliance that fits the human oral cavity; the inside of the first base body 10 is provided with a cooling pipe group 11, a spray pipe group 14 and a flow-through channel 17.

[0042] Among them, the cooling pipe group 11 is arranged in the middle of the first base body 10 and includes a first inlet pipe 12 for liquid inlet and a first return pipe 13 for liquid discharge, which is used to provide flowing coolant inside the first base body 10. The coolant with a relatively low temperature is provided inside the first base body 10 through the first inlet pipe 12. After heat exchange with the oral cavity, the coolant is then discharged through the first return pipe 13, thereby taking away the heat inside the patient's oral cavity and achieving the effect of rapid cooling. In addition, the cooling pipe group 11 can also be provided with openings, so that it can be connected to the oral cavity similar to the spray pipe group. In this way, the coolant inside the first inlet pipe 12 can enter the patient's oral cavity through the first base body 10 and then be discharged through the first return pipe 13, thereby improving the cooling efficiency.

[0043] The spray pipe group 14 is arranged on the outer edge of the first base body 10 and includes a second inlet pipe 15 for liquid inlet and a second return pipe 16 for liquid discharge. The second inlet pipe 15 and the second return pipe 16 are arranged on the left and right sides of the first base body 10 respectively. A spray assembly 40 is also arranged at the outer edge of the outer surface of the first base body 10. The spray assembly 40 is connected to the spray pipe group 14. The spray assembly 40 can be provided with a plurality of spray outlets, so that the flushing liquid can enter the spray assembly 40 through the spray pipe group 14 to realize oral cavity cleaning. The spray assembly 40 can spray the flushing liquid into the patient's oral cavity from multiple angles at the outer edge of the first base body 10, thereby cleaning the patient's oral cavity comprehensively and avoiding cleaning dead corners.

[0044] The flow-through channel 17 is arranged in the middle of the first base body 10. The flow-through channel 17 includes an opening arranged on the surface of the first base body 10, so as to facilitate the connection between the flow-through channel 17 and the patient's oral cavity, which is used to collect and discharge the flushing liquid in the oral cavity. A valve body 18 is arranged in the flow-through channel 17, which is used to close or connect the flow-through channel 17.

[0045] Both the flushing liquid for flushing the oral cavity and the coolant discharged from the cooling pipe group 11 into the oral cavity can be discharged from the oral cavity through the flow-through channel 17. In order to ensure the liquid discharge effect, the discharge end of the cooling pipe group 11, that is, the first return pipe 13, and the discharge end of the flow-through channel 17 can both be connected to the micro pump body.

[0046] In addition, the rear end of the first base body 10 is connected to a second base body 20. A baffle 21 is arranged at one end of the second base body 20 close to the first base body 10. A gasket can also be arranged on the side of the baffle 21 facing the first base body 10. The baffle 21 has a certain bending arc, and the baffle 21 is used to assist in closing the patient's mouth during use. In this way, on the one hand, it helps to fix the first base body 10 inside the patient's oral cavity, and on the other hand, it can also prevent the flushing liquid from dripping from the patient's mouth corners during the flushing process, improving the patient's use comfort. The cooling pipeline and the flushing pipeline both pass through the second base body 20 and are connected to the external pipeline.

[0047] The cooling pipe group 11 and the flushing pipe group 14 are independently arranged, so that oral cavity cooling treatment can be carried out while cleaning the oral cavity. Oral cavity cleaning or oral cavity cooling can also be carried out separately. Moreover, the cooling liquid entering the patient's oral cavity can be discharged through the flow-through channel 17 or through the first return pipe 13 in the cooling pipe group 11. In addition, the flushing liquid and the cooling liquid in the oral cavity can also be spit out manually after the first base body 10 is taken out. The usage modes are diversified, which can meet different usage scenarios and different usage requirements, and have strong adaptability.

[0048] In addition, the cooling liquid flows through the first inlet pipe 12 and the first return pipe 13 in the cooling pipe group 11 to perform basic cooling treatment on the oral cavity, only taking away the heat in the oral cavity. By the flow of the cooling pipe group 11 inside the first base body 10, the heat in the oral cavity is absorbed and taken out. In this process, the flow-through channel 17 can be in an open state, which is convenient for the gas in the oral cavity of the person to be discharged, thereby improving the comfort of the patient.

[0049] A tongue-shaped auxiliary component 30 is also arranged inside the U-shaped first base body 10. The cooling pipe group 11 extends from the inside of the first base body 10 to the inside of the auxiliary component 30. In this way, by laying the cooling pipe group 11 in the auxiliary component 30, the temperature reduction treatment of the tongue surface area can be realized, so that the temperature inside the oral cavity can reach equilibrium quickly and the cooling effect is improved.

[0050] An auxiliary channel 31 is arranged inside the auxiliary component 30, and the auxiliary channel 31 is communicated with the flow-through channel 17. A plurality of through holes 37 are arranged on the surface of the auxiliary component 30, and all the plurality of through holes 37 are communicated with the auxiliary channel 31. The auxiliary channel 31 includes a plurality of openings arranged on the surface of the auxiliary component 30. The plurality of through holes 37 can be respectively arranged at positions such as the end part, the bottom surface and the top surface of the auxiliary component 30. In this way, the flushing liquid and / or the cooling liquid in the oral cavity can be gathered towards the flow-through channel 17 from different directions, which is convenient for the discharge of the flushing liquid and / or the cooling liquid.

[0051] An extension strip 32 is arranged at the outer edge of the through hole 37 arranged on the bottom surface of the auxiliary component 30. The extension strip 32 extends outward from the outer surface of the auxiliary component 30, and the extension strip 32 is provided with a notch 33. The bottom surface of the auxiliary component 30 is attached to the patient's tongue surface. The arrangement of the extension strip 32 can prevent the auxiliary component 30 from being overly attached to the tongue and prevent adhesion between the two, and can avoid excessive cooling of the tongue surface. The arrangement of the extension strip 32 forms a spaced space between the tongue and the auxiliary component 30. In this way, the flushing liquid sprayed by the spraying component 40 into the oral cavity can flow on the tongue surface, so as to ensure the flushing of the tongue surface, prevent the occurrence of cleaning dead corners, and the flow space of the flushing liquid is enlarged, and the flushing effect is improved.

[0052] The spraying assembly 40 is arranged corresponding to the positions of teeth, gums, etc. inside the oral cavity, which helps to spray and cool each area of the oral cavity, and can also clean and cool the tongue area during the process of discharging the flushing liquid. The spraying assembly 40 includes a first spraying plate 41 and a second spraying plate 42 arranged correspondingly. The first spraying plate 41 and the second spraying plate 42 are in contact with each other, and a drainage channel 43 is arranged between them. The drainage channel 43 is communicated with the spraying pipe group 14.

[0053] A spraying base 51 is arranged between the first spraying plate 41 and the second spraying plate 42. A spraying channel is arranged in the middle of the spraying base 51. One end of the spraying channel is communicated with the drainage channel 43. The outer edge of the side of the spraying base 51 close to the first spraying plate 41 is provided with an inclined surface 52. Along the radial direction of the spraying base 51, the inclined surface 52 gradually extends from the inside to the outside towards the direction close to the second spraying plate 42. By arranging the inclined surface 52, the flushing liquid inside the drainage channel 43 can be promoted to converge towards the middle of the spraying base 51, and then discharged through the spraying channel.

[0054] A drainage channel 43 capable of allowing liquid to flow through is formed between the first spraying plate 41 and the second spraying plate 42. The spraying base 51 is arranged inside the drainage channel 43. A gap is left between the top surface of the spraying base 51 and the first spraying plate 41, so as to realize the communication between the spraying channel and the drainage channel 43.

[0055] After the flushing liquid enters the drainage channel 43, the space between the first spraying plate 41 and the second spraying plate 42 will expand, so that the contact state between the first base body 10 and the oral cavity can be changed. For example, this expansion effect causes the contact area between the first spraying plate 41, the second spraying plate 42 of the spraying assembly 40 and the gums and teeth in the oral cavity to change, which can avoid the discomfort of the patient caused by the continuous single contact state between the first base body 10 and the inside of the oral cavity; and the adjustment of the contact state enables the contact part to be cleaned by the flushing liquid, thus avoiding the growth of bacteria around due to continuous contact; in addition, after expansion, the contact area between the first base body 10 and the inner wall of the oral cavity is reduced, the flushing range of the liquid after spraying is expanded, the flushing dead angle is reduced, which helps to discharge dirt and bacteria.

[0056] Specifically, the spraying channel is of a hourglass structure. The outlet end of the spraying channel is arranged on the surface of the second spraying plate 42. The spraying channel includes a first tapered hole 53, a connecting channel 54 and a second tapered hole 55 connected in sequence. One end of the first tapered hole 53 far away from the second tapered hole 55 is communicated with the drainage channel 43. One end of the second tapered hole 55 far away from the first tapered hole 53 is provided with a spraying outlet on the surface of the second spraying plate 42. During the process of discharging the flushing liquid, the flushing liquid in the drainage channel 43 can pass through the inclined surface 52 on the spraying base 51, and then enter the first tapered hole 53, the connecting channel and then be discharged from the spraying outlet of the second tapered hole 55.

[0057] The outlet end of the spray channel is provided with a diversion convex ring 56. The diversion convex ring 56 is arranged around the outlet end of the spray channel, and the diversion convex ring 56 is provided with a turbine-shaped groove 57.

[0058] The setting of the spray washing base 51 helps to increase the flow rate of the flushing liquid when it enters the spray channel; the settings of the first tapered hole 53 and the second tapered hole 55 cause the flushing liquid entering the spray channel to generate a swirl and discharge in a swirling manner, which further increases the flow rate of the flushing liquid and changes its flow direction, improving the flushing effect on the oral cavity and expanding the flushing range. The diversion convex ring 56 is provided with a turbine-shaped groove 57, which also helps to guide the flushing liquid to flow in different directions and further expands the flushing range. In addition, the setting of the diversion convex ring 56 avoids the continuous contact between the first spray plate 41, the second spray plate 42 and the teeth and gums in the oral cavity, as well as the problem of too large contact area, improving the comfort level.

[0059] Embodiment 2 Figures 8 to 9 Schematically shows an oral cavity low-temperature rinser for reducing oral mucositis according to another embodiment of the present invention. The difference from Embodiment 1 is that: The auxiliary component 30 includes two auxiliary plates 34 arranged symmetrically left and right. The auxiliary plates 34 are made of flexible materials, so that they can better fit the shape of the tongue and avoid discomfort caused by too hard materials. The cooling pipe group 11 is adaptively laid inside the two auxiliary plates 34, and auxiliary channels 31 are arranged in both of the two auxiliary plates 34 for communicating with the flow-through channel 17.

[0060] A connecting member is arranged between the two auxiliary plates 34. The connecting member includes a rotating rod 35 and an elastic member 36. The elastic member 36 is arranged between the two rotating rods 35. The ends of the two rotating rods 35 far from the elastic member 36 are respectively connected to the two auxiliary plates 34. The elastic member 36 is movably matched with the rotating rod 35. Under the interaction between each other, the relative position and direction between the elastic member 36 and the rotating rod 35 can be adjusted. Moreover, the elastic member 36 has a certain elasticity and can be deformed to a certain extent under the action of the two rotating rods 35, thereby realizing the adjustment of the gap size between the two auxiliary plates 34. The auxiliary plates 34 can move and adjust their positions inside the first base body 10, so as to improve the wearing comfort of the rinser as much as possible, and the heat exchange range of the cooling pipe group 11 in the oral cavity can be expanded by the movable auxiliary plates 34.

[0061] By dividing the auxiliary component 30 into two symmetrical parts, with a certain gap distance between the two auxiliary plates 34 and connected by an elastic member 36 and a rotating rod 35 in the middle, during spraying, the gap between the auxiliary plates 34 can be enlarged by the movement of the tongue, which helps the flow and discharge of the flushing liquid. By designing the elastic member 36 and the auxiliary plates 34, etc., when the gap between the two auxiliary plates 34 is enlarged, it helps the lumps or other dirt in the oral cavity to enter the auxiliary channel 31, so as to improve the cleaning effect.

[0062] By arranging the auxiliary plate 34 and the elastic member 36, the auxiliary plate 34 has a certain range of up and down movement, thus releasing the movement space of the tongue and adapting to people with different tongue sizes for use, improving the comfort. The arrangement of the auxiliary plate 34 forms contact with the surface of the tongue and can even contact the oral palate, so as to avoid excessive shaking of the first base body 10 in the oral cavity, thereby avoiding the aggravation of the frictional contact between the first base body 10 and the teeth and the skin of the oral cavity inner wall, etc., and strengthening the protection of the oral cavity.

[0063] Embodiment 3 Figure 10 Schematically shows an oral low-temperature irrigator for reducing oral mucositis according to another embodiment of the present invention. The difference from Embodiment 1 is as follows: The cooling pipe group 11 is connected to the control box through the first connecting pipe body 62. The control box is used to supply coolant to the cooling pipe group 11. A compressor 63 is arranged inside the control box. The compressor 63 cooperates with the refrigerant to cool the local environment inside the control box, so as to refrigerate the coolant flowing through the control box and ensure that the coolant entering the oral cavity is in a low-temperature state. In addition, the spray pipe group 14 can also be connected to the control box through a second connecting pipe body (not marked in the figure), and the control box supplies the flushing liquid to the spray pipe group 14. The first connecting pipe body 62 and the second connecting pipe body cooperate with a valve body (not marked in the figure) respectively, so as to regulate the flow states of the coolant and the flushing liquid.

[0064] Two substrates 61 are arranged inside the control box, and there is a gap between the two substrates 61; a plurality of heat dissipation fins 64 arranged side by side are arranged above the two substrates 61. The first connecting pipe body 62 cooperates with the heat dissipation fins 64, and a heat dissipation fan 65 is arranged on the side of the plurality of heat dissipation fins 64.

[0065] In this way, there is a gap between the two substrates 61 arranged. The direction of the air discharged by the heat dissipation fan 65 is not limited to one side of the heat dissipation fins 64, and heat exchange can also be carried out by discharging air flow to the bottom. In this way, the heat exchange area is increased, and thus the heat concentration at a single position of the control box is avoided, effectively improving the balance of the ambient temperature. In addition, the expansion of the heat exchange area can reduce the air flow discharge flow rate at a single position, and thus reduce the wind noise.

[0066] The routine operations in the operation steps of the present invention are well-known to those skilled in the art and will not be elaborated herein.

[0067] The above-described embodiments have described the technical solutions of the present invention in detail. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, supplements, or substitutions in a similar manner within the principle scope of the present invention should be included within the protection scope of the present invention.
