Description

Technical Field

[0001] The present invention relates to the technical field of oral cleaning devices, and particularly to an oral cleaning device. Background Art

[0002] Brushing teeth is the most popular self-dental care behavior. Brushing can solve the problem of cleaning the tooth surfaces that the toothbrush can reach. However, for cleaning the tooth surfaces on both sides of the tooth gaps, especially the gingival sulcus, other dental cleaning and care products are still needed. Therefore, as an auxiliary supplement to the toothbrush, a dental irrigator is used to clean the areas that are not easily cleaned by the toothbrush, such as tooth gaps and gingival sulci.

[0003] A dental irrigator generally includes a housing, a water tank, a water pump, and a nozzle. The water inlet of the water pump is connected to the water tank, and the water outlet of the water pump is connected to the nozzle. The food residue and debris in the tooth gaps are flushed out by the water flow ejected from the nozzle to achieve the purpose of protecting dental health. However, most of the dental irrigators on the market currently only have the flushing function and lack the function of further oral care (such as teeth whitening, fresh breath, and gingival anti-inflammatory). Summary of the Invention

[0004] Based on this, the purpose of the present invention is to overcome the deficiencies of the prior art and provide an oral cleaning device. By adding reagent particles with care functions into a reagent container and ejecting a reagent water flow through a supporting nozzle, the oral cavity of the user is cleaned and cared for, so as to improve the ability to clean the oral cavity.

[0005] To achieve the above purpose, an embodiment of the present invention provides an oral cleaning device, including:

[0006] A main body having a water outlet pipe;

[0007] A reagent container having a reagent cavity and a reagent pipe. The reagent pipe is communicated with the reagent cavity. The reagent container is connected to the water outlet pipe, and a check valve is provided between the reagent container and the water outlet pipe;

[0008] A nozzle having a jet orifice, and the nozzle is connected to the reagent container.

[0009] Thus, for the oral cleaning device according to the embodiments of the present invention, by providing a reagent container between the main body and the nozzle, in this way, reagent particles with care functions are added into the reagent chamber through the reagent pipeline, and the main body is used to convey water flow to the water outlet pipeline. The water flow flows into the reagent chamber of the reagent container after passing through the check valve, and is mixed and dissolved with the reagent particles in the reagent chamber to form a reagent water flow. The reagent water flow then enters the nozzle and is finally ejected through the ejection orifice of the nozzle and enters the user's oral cavity to clean and care for the user's oral cavity; wherein, the check valve can prevent the backflow of the reagent water flow into the water outlet pipeline, thereby effectively preventing the reagent water flow from contaminating the main body. That is to say, for the oral cleaning device according to the embodiments of the present invention, by adding reagent particles into the reagent container, it is convenient for the oral cleaning device to clean and care for the oral cavity.

[0010] As an implementation manner, the main body includes a housing, a water tank, and a pump body assembly. The water tank and the pump body assembly are respectively arranged in the housing. The pump body assembly is respectively connected to the water tank and the flushing pipeline, and the pump body assembly is used to pump the liquid in the water tank into the flushing pipeline.

[0011] As an implementation manner, a filter screen is arranged between the ejection orifice of the nozzle and the reagent container. Thus, by filtering the reagent water flow through the filter screen, it is possible to effectively prevent the small particle reagents dissolved in the reagent water flow from entering the nozzle, effectively improving the user experience.

[0012] As an implementation manner, the reagent container is fixedly arranged inside the housing. The reagent pipeline penetrates through the surface of the housing, and the nozzle is detachably connected to the reagent pipeline. Thus, by detachably installing the nozzle on the reagent pipeline, it is convenient for cleaning and replacing the nozzle, and it does not prevent the input of reagent particles.

[0013] As an implementation manner, a flushing pipeline communicating with the reagent chamber is arranged on the reagent container. The flushing pipeline penetrates through the surface of the housing, and the nozzle is detachably connected to the flushing pipeline. Thus, by detachably installing the nozzle on the flushing pipeline, it is convenient for cleaning and replacing the nozzle.

[0014] As an implementation manner, the reagent pipeline penetrates through the surface of the housing, and the reagent pipeline is detachably connected with a lid.

[0015] As an implementation manner, the water outlet pipeline penetrates through the surface of the housing. The reagent container is detachably connected to the housing. A connecting pipeline communicating with the reagent chamber is arranged on the reagent container, and the connecting pipeline is detachably connected to the water outlet pipeline. Thus, by detachably installing the reagent container on the water outlet pipeline, it is convenient for cleaning and replacing the reagent container.

[0016] As an implementation manner, a groove is formed by the depression on the surface of the housing, the water outlet pipe penetrates through the groove, and the reagent container is partially or entirely arranged in the groove. Thus, by arranging the reagent container partially or entirely in the groove, the volume of the reagent container exposed on the surface of the housing can be reduced, making the overall oral cleaning device more aesthetically pleasing.

[0017] As an implementation manner, the nozzle is detachably connected to the reagent pipe, and the nozzle is communicated with the reagent cavity. Thus, by detachably installing the nozzle on the reagent pipe, it is convenient for cleaning and replacing the nozzle and does not hinder the input of reagent particles.

[0018] As an implementation manner, the nozzle is fixedly connected to the reagent pipe, and the nozzle is communicated with the reagent cavity; a reagent inlet communicating with the reagent cavity is formed on the reagent container and / or the nozzle, and a lid is arranged on the reagent inlet.

[0045] Brushing teeth is the most popular self-dental care behavior. Brushing teeth can solve the problem of cleaning the tooth surfaces that the toothbrush can reach. However, for cleaning the tooth surfaces on both sides of the tooth gaps, especially the gingival sulcus, other dental cleaning and care products are still needed. Therefore, the dental irrigator is an auxiliary supplement to the toothbrush, which can clean the areas that are not easily cleaned by the toothbrush, such as the tooth gaps and the gingival sulcus. Among them, the dental irrigator generally includes a housing, a water tank, a water pump and a nozzle. The water inlet of the water pump is connected to the water tank, and the water outlet of the water pump is connected to the nozzle. The food residue and debris in the tooth gaps are flushed away by the water flow ejected from the nozzle, so as to achieve the purpose of protecting dental health. However, most of the dental irrigators on the market at present only have the flushing function and lack the function of further nursing the oral cavity (such as whitening teeth, freshening breath and anti-inflammatory of the gums, etc.).

[0046] In view of this, the present invention provides an oral cleaning device. By adding reagent particles with nursing functions into the reagent container and spraying the reagent water flow through the supporting nozzle, the oral cavity of the user can be cleaned and nursed, so as to improve the ability to clean the oral cavity.

[0047] Please refer toFigures 1 to 4 ; The present invention provides an oral cleaning device, comprising:

[0048] A main body 10 having a water outlet pipe 11;

[0049] A reagent container 30 having a reagent cavity 31 and a reagent pipe 32. The reagent pipe 32 is communicated with the reagent cavity 31. The reagent container 30 is connected to the water outlet pipe 11, and a check valve 20 is arranged between the reagent container 30 and the water outlet pipe 11;

[0050] A nozzle 40 having a jet orifice 41. The nozzle 40 is connected to the reagent container 30.

[0051] Thus, for the oral cleaning device according to the present invention, by arranging the reagent container 30 between the main body 10 and the nozzle 40, in this way, reagent particles with nursing functions are added into the reagent cavity 31 through the reagent pipe 32, and the main body 10 is used to convey water flow to the water outlet pipe 11. The water flow flows into the reagent cavity 31 of the reagent container 30 after passing through the check valve 20, and is mixed and dissolved with the reagent particles in the reagent cavity 31 to form a reagent water flow. The reagent water flow then enters the nozzle 40, and finally is ejected through the jet orifice 41 of the nozzle 40 and enters the user's oral cavity to clean and nurse the user's oral cavity; wherein, the check valve 20 can prevent the reagent water flow from flowing back into the water outlet pipe 11, thereby effectively preventing the reagent water flow from contaminating the main body 10. That is to say, for the oral cleaning device according to the embodiment of the present invention, by adding reagent particles into the reagent container 30, it is convenient for the oral cleaning device to clean and nurse the oral cavity.

[0052] As Figure 3 and Figure 4 shown, the main body 10 of the present invention comprises a housing, a water tank 13, and a pump body assembly 12. The water tank 13 and the pump body assembly 12 are respectively arranged in the housing. The pump body assembly 12 is respectively connected to the water tank 13 and a flushing pipe 37, and the pump body assembly 12 is used to pump the liquid in the water tank 13 into the flushing pipe 37.

[0053] Wherein, the water tank 13 of the present invention may be provided with a water injection port penetrating through the side wall of the housing and communicating with the inside of the water tank 13, and a water cover is covered on the water injection port, so that the user can inject water flow into the inside of the water tank 13 through the water injection port. In addition, a control circuit board for controlling the start or stop of the pump body assembly 12 is arranged in the housing of the present invention, a storage battery for supplying power to the pump body assembly 12 is arranged in the housing, and a switch button is arranged on the surface of the housing to facilitate the user to operate the opening and closing of the main body 10.

[0054] A filter screen 42 is provided between the injection port 41 of the nozzle 40 of the present invention and the reagent container 30. Thus, the reagent water flow is filtered by the filter screen 42, which can effectively prevent small particle reagents dissolved in the reagent water flow from entering the nozzle 40, effectively improving the user experience.

[0055] As Figure 5 shown, in some embodiments of the present invention, the check valve 20 is disposed in the reagent container 30. The check valve 20 includes a valve seat 21, a valve stem 22, and a spring 23. The valve seat 21 is provided with a water inlet communicating with the water outlet pipe 11 and a water outlet communicating with the reagent chamber 31. The valve stem 22 is telescopically disposed on the valve seat 21 through the spring 23, and one end of the valve stem 22 blocks the water inlet and is pressed tightly against the water inlet by the force of the spring 23. Thus, the check valve 20 can block the water inlet, and when water flows out from the water outlet pipe 11, the valve stem 22 can be pushed open to allow the water flow to enter the reagent chamber 31 of the reagent container 30.

[0056] As Figure 6 shown, in some embodiments of the present invention, the water outlet pipe 11 and the pump body assembly 12 are integrally formed. The check valve 20 is disposed in the water outlet pipe 11. The check valve 20 includes a valve seat 21, a valve stem 22, and a spring 23. The valve seat 21 is disposed in the water outlet pipe 11. The valve seat 21 is provided with a water inlet communicating with the water outlet pipe 11 and a water outlet communicating with the connecting pipe 38. The valve stem 22 is telescopically disposed on the valve seat 21 through the spring 23, and one end of the valve stem 22 blocks the water inlet and is pressed tightly against the water inlet by the force of the spring 23. Thus, the check valve 20 can block the water inlet, and when the water flow in the water outlet pipe 11 passes through the water inlet of the valve seat 21, the valve stem 22 can be pushed open to allow the water flow to pass through the check valve 20 and enter the reagent container 30 from the end of the water outlet pipe 11.

[0057] In this way, when the main body 10 is started, the pump body assembly 12 pumps the water in the water tank 13 into the water outlet pipe 11 to form a water flow. The water flow can push open the check valve 20 and enter the reagent chamber 31. At this time, the water flow is mixed and dissolved with the reagent particles in the reagent chamber 31 to form a reagent water flow. The reagent water flow is filtered by the filter screen 42 and then enters the nozzle 40, and finally is ejected from the injection port 41 of the nozzle 40 into the user's oral cavity for cleaning and care.

[0058] As Figures 7 to 9As shown in the figure, the filter screen 42 of the present invention can be arranged at one end of the nozzle 40 away from the injection port 41. At one end of the nozzle 40 connected to the reagent container 30, a holder 43 is detachably arranged, and the filter screen 42 is fixed in the nozzle 40 through the holder 43. In this way, the reagent water flow can be filtered through the filter screen 42, and it is also convenient to disassemble the holder 43 and clean or replace the filter screen 42. In addition, in some other embodiments, the filter screen 42 can also be arranged in the reagent container 30.

[0059] Optionally, in some embodiments of the present invention, the reagent container 30 is fixedly arranged inside the housing, the reagent pipeline 32 penetrates through the surface of the housing, and the nozzle 40 is detachably connected to the reagent pipeline 32. Thus, by detachably installing the nozzle 40 on the reagent pipeline 32, it is convenient to clean and replace the nozzle 40, and it does not prevent the input of reagent particles; in addition, using the reagent pipeline 32 as the connection channel of the nozzle 40 enables the reagent pipeline 32 to be used as both the input channel of reagent particles and the ejection channel of reagent water flow, without the need to additionally open a pipeline connected to the nozzle 40 on the reagent container 30.

[0060] In these embodiments, one end of the nozzle 40 can be threadedly connected to the reagent pipeline 32 or detachably installed in the reagent pipeline 32 by means of a snap 35 or the like. In addition, in order to improve the sealing performance between the nozzle 40 and the reagent pipeline 32, a waterproof sealing ring 36 can be arranged between the nozzle 40 and the reagent pipeline 32, thereby improving the sealing performance between the two.

[0061] Optionally, in some embodiments of the present invention, the reagent container 30 is fixedly arranged inside the housing, a flushing pipeline 37 communicating with the reagent cavity 31 is arranged on the reagent container 30, the flushing pipeline 37 penetrates through the surface of the housing, and the nozzle 40 is detachably connected to the flushing pipeline 37. Thus, by detachably installing the nozzle 40 on the flushing pipeline 37, it is convenient to clean and replace the nozzle 40. Among them, the reagent pipeline 32 penetrates through the surface of the housing, and a lid 34 is detachably connected to the reagent pipeline 32.

[0062] In these embodiments, one end of the nozzle 40 can be threadedly connected to the flushing pipeline 37 or detachably installed in the flushing pipeline 37 by means of a snap 35 or the like. In order to improve the sealing performance between the nozzle 40 and the flushing pipeline 37, a waterproof sealing ring 36 can be arranged between the nozzle 40 and the flushing pipeline 37, thereby improving the sealing performance between the two. In addition, by arranging a lid 34 on the reagent pipeline 32, the sealing performance of the reagent pipeline 32 can be improved. It can be understood that in these embodiments, the reagent pipeline 32 serves as the input channel of reagent particles, and the flushing pipeline 37 serves as the ejection pipeline connecting the nozzle 40, for the reagent water flow to eject and enter the nozzle 40.

[0063] Optionally, in some embodiments of the present invention, the water outlet pipe 11 penetrates through the surface of the housing, the reagent container 30 is detachably connected to the housing, a connection pipe 38 communicating with the reagent cavity 31 is provided on the reagent container 30, and the connection pipe 38 is detachably connected to the water outlet pipe 11. Thus, by detachably mounting the reagent container 30 on the water outlet pipe 11 and placing the reagent container 30 outside the housing, it is convenient to clean and replace the reagent container 30.

[0064] In these embodiments, one end of the nozzle 40 can be threadedly connected to the reagent pipe 32 or detachably mounted in the reagent pipe 32 by means of a buckle 35 or the like. That is to say, by using the reagent pipe 32 as the connection channel of the nozzle 40, the reagent pipe 32 can be used both as the input channel of the reagent particles and as the ejection channel of the reagent water flow, without additionally opening a pipe connected to the nozzle 40 on the reagent container 30. In addition, in order to improve the sealing performance between the nozzle 40 and the reagent pipe 32, a waterproof sealing ring 36 can be provided between the nozzle 40 and the reagent pipe 32, thereby improving the sealing performance between the two.

[0065] Optionally, in some embodiments of the present invention, the reagent container 30 is detachably connected to the housing, a groove 14 is formed by the depression on the surface of the housing, the water outlet pipe 11 penetrates through the groove 14, the reagent container 30 is partially or entirely disposed in the groove 14, and a connection pipe 38 communicating with the reagent cavity 31 is provided on the reagent container 30, and the connection pipe 38 is detachably connected to the water outlet pipe 11. Thus, by partially or entirely disposing the reagent container 30 in the groove 14, the volume of the reagent container 30 exposed on the surface of the housing can be reduced, making the overall oral cleaning device more beautiful.

[0066] In these embodiments, one end of the nozzle 40 can be threadedly connected to the reagent pipe 32 or detachably mounted in the reagent pipe 32 by means of a buckle 35 or the like. That is to say, by using the reagent pipe 32 as the connection channel of the nozzle 40, the reagent pipe 32 can be used both as the input channel of the reagent particles and as the ejection channel of the reagent water flow, without additionally opening a pipe connected to the nozzle 40 on the reagent container 30. In addition, in order to improve the sealing performance between the nozzle 40 and the reagent pipe 32, a waterproof sealing ring 36 can be provided between the nozzle 40 and the reagent pipe 32, thereby improving the sealing performance between the two.

[0067] Optionally, in some embodiments of the present invention, the water outlet pipe 11 penetrates the surface of the housing, the reagent container 30 is detachably connected to the housing, a connecting pipe 38 communicating with the reagent chamber 31 is provided on the reagent container 30, and the connecting pipe 38 is detachably connected to the water outlet pipe 11. Thus, by detachably mounting the reagent container 30 on the water outlet pipe 11 and placing the reagent container 30 outside the housing, it is convenient to clean and replace the reagent container 30.

[0068] In these embodiments, the nozzle 40 is connected to the reagent pipe 32 and the nozzle 40 communicates with the reagent chamber 31; a reagent inlet 33 communicating with the reagent chamber 31 is provided on the reagent container 30 and / or the nozzle 40, and a lid 34 is provided on the reagent inlet 33. That is to say, in these embodiments, the nozzle 40 and the reagent container 30 are provided as an integral structure, and the nozzle 40 and the reagent container 30 are fixedly connected. At this time, the reagent pipe 32 serves as a spraying channel for the reagent water flow, allowing the reagent water flow to enter the nozzle 40; while the reagent inlet 33 serves as an input channel for the reagent particles, and the reagent inlet 33 is hermetically covered with the lid 34 to maintain the tightness of the reagent chamber 31. Among them, the combination between the reagent container 30 and the nozzle 40 includes but is not limited to connection methods such as snap connection, screw connection, and integral molding.

[0069] As Figure 10 shown, in some embodiments of the present invention, the reagent container 30 and the nozzle 40 are combined by a screw connection method, and a waterproof sealing ring 36 is provided between the nozzle 40 and the reagent container 30. A reagent inlet 33 for injecting reagent particles is provided on the reagent container 30, and a lid 34 is detachably connected to the reagent inlet 33.

[0070] The following Figures 11 to 12 specific embodiment of the oral cleaning device according to the present invention will be described in detail. It should be understood that the following is only an illustrative description and should not be construed as a limitation of the present invention.

[0071] This embodiment provides an oral cleaning device, including a main body 10, a reagent container 30, and a nozzle 40. The main body 10 has a water outlet pipe 11; the reagent container 30 has a reagent chamber 31 and a reagent pipe 32, the reagent pipe 32 communicates with the reagent chamber 31, the reagent container 30 is connected to the water outlet pipe 11, and a check valve 20 is provided between the reagent container 30 and the water outlet pipe 11; the nozzle 40 has a jet port 41, and the nozzle 40 is connected to the reagent container 30. Among them, the reagent container 30 is fixedly arranged inside the housing, the reagent pipe 32 penetrates the surface of the housing, and the nozzle 40 is detachably connected to the reagent pipe 32.

[0072] In this embodiment, the main body 10 includes a housing, a water tank 13, and a pump assembly 12. The water tank 13 and the pump assembly 12 are respectively disposed in the housing. The pump assembly 12 is respectively connected to the water tank 13 and the flushing pipeline 37, and the pump assembly 12 is configured to pump the liquid in the water tank 13 into the flushing pipeline 37. Secondly, a filter screen 42 is provided between the nozzle 40 and the reagent container 30 in this embodiment. The filter screen 42 is disposed on the nozzle 40. A retainer 43 is detachably provided at one end of the nozzle 40 connected to the reagent container 30, and the filter screen 42 is fixed in the nozzle 40 through the retainer 43. Further, the nozzle 40 in this embodiment can be threadedly connected to the reagent pipeline 32 or detachably installed in the reagent pipeline 32 by means of a buckle 35 or the like.

[0073] In addition, the check valve 20 in this embodiment is disposed in the reagent container 30. The check valve 20 includes a valve seat 21, a valve stem 22, and a spring 23.

The valve stem 22 is telescopically disposed on the valve seat 21 through the spring 23, and one end of the valve stem 22 blocks the water inlet and is pressed tightly against the water inlet by the acting force of the spring 23. Thus, the check valve 20 can block the water inlet, and when the water flows out from the water outlet pipeline 11, the valve stem 22 can be pushed open and the water can enter the reagent cavity 31 of the reagent container 30.

[0074] Therefore, when the oral cleaning device in this embodiment is in use, first, the nozzle 40 is detached from the reagent pipeline 32, and reagent particles with nursing functions such as whitening and stain removal are put into the reagent pipeline 32, and then the nozzle 40 is installed in the reagent pipeline 32. Then, the main body 10 is started, and the pump assembly 12 pumps the water in the water tank 13 into the water outlet pipeline 11 to form a water flow. When the water flow passes through the check valve 20, the valve stem 22 can be pushed open and enter the reagent cavity 31. At this time, the water flow is mixed and dissolved with the reagent particles in the reagent cavity 31 to form a reagent water flow. The reagent water flow is ejected from the reagent pipeline 32, filtered through the filter screen 42, and then enters the nozzle 40, and finally is ejected from the ejection port 41 of the nozzle 40 into the user's oral cavity for cleaning and nursing.

The pump assembly 12 is respectively connected to the water tank 13 and the flushing pipe 37, and the pump assembly 12 is used to pump the liquid in the water tank 13 into the flushing pipe 37. Secondly, a filter screen 42 is arranged between the nozzle 40 and the reagent container 30 of this embodiment. The filter screen 42 is arranged on the nozzle 40. A retaining frame 43 is detachably arranged at one end where the nozzle 40 is connected to the reagent container 30, and the filter screen 42 is fixed in the nozzle 40 through the retaining frame 43. Further, the nozzle 40 of this embodiment can be threadedly connected to the reagent pipe 32 or detachably installed in the reagent pipe 32 by means of a buckle 35 or the like.

[0078] In addition, the check valve 20 of this embodiment is arranged in the reagent container 30. The check valve 20 includes a valve seat 21, a valve rod 22, and a spring 23. The valve seat 21 is provided with a water inlet communicated with the water outlet pipe 11 and a water outlet communicated with the reagent cavity 31. The valve rod 22 is telescopically arranged on the valve seat 21 through the spring 23, and one end of the valve rod 22 blocks the water inlet and is tightly pressed against the water inlet by the acting force of the spring 23, so that the check valve 20 can block the water inlet, and the valve rod 22 can be pushed open and the water flow can enter the reagent cavity 31 of the reagent container 30 only when the water flow is ejected from the water outlet pipe 11.

[0079] Thus, when the oral cleaning device of this embodiment is in use, first, reagent particles with care functions such as whitening and stain removal are put into the reagent pipeline 32, and then the lid 34 is covered to seal the reagent pipeline 32. Then, the main body 10 is started, and the pump body assembly 12 pumps the water in the water tank 13 into the water outlet pipeline 11 to form a water flow. When the water flow passes through the check valve 20, the valve stem 22 can be pushed open and enter the reagent cavity 31. At this time, the water flow is mixed and dissolved with the reagent particles in the reagent cavity 31 to form a reagent water flow. The reagent water flow is ejected from the flushing pipeline 37, filtered through the filter screen 42, and then enters the nozzle 40. Finally, it is ejected from the ejection port 41 of the nozzle 40 and enters the user's oral cavity for cleaning and care.

[0080] Next, in conjunction with Figures 15 to 16 A specific embodiment of the oral cleaning device according to the present invention will be described in detail. It should be understood that the following is only an exemplary illustration and should not be construed as a limitation to the present invention.

[0081] This embodiment provides an oral cleaning device, including a main body 10, a reagent container 30, and a nozzle 40. The main body 10 has a water outlet pipeline 11; the reagent container 30 has a reagent cavity 31 and a reagent pipeline 32. The reagent pipeline 32 is communicated with the reagent cavity 31. The reagent container 30 is connected to the water outlet pipeline 11, and a check valve 20 is provided between the reagent container 30 and the water outlet pipeline 11; the nozzle 40 has an ejection port 41, and the nozzle 40 is connected to the reagent container 30.

[0082] In this embodiment, the water outlet pipeline 11 penetrates the surface of the housing. The reagent container 30 is detachably connected to the housing, and the reagent container 30 is externally disposed on the housing. A connecting pipeline 38 communicating with the reagent cavity 31 is provided on the reagent container 30, and the connecting pipeline 38 is detachably connected to the water outlet pipeline 11. Thus, by detachably installing the reagent container 30 on the water outlet pipeline 11 and externally disposing the reagent container 30 on the housing, it is convenient to clean and replace the reagent container 30.

[0083] Among them, the connecting pipeline 38 can be threadedly connected to the water outlet pipeline 11, or can be installed on the water outlet pipeline 11 by means of a buckle 35 or the like. In addition, a filter screen 42 is provided between the nozzle 40 and the reagent container 30 of this embodiment. The filter screen 42 is provided on the nozzle 40. A retaining frame 43 is detachably provided at one end where the nozzle 40 is connected to the reagent container 30, and the filter screen 42 is fixed in the nozzle 40 through the retaining frame 43. Further, the nozzle 40 of this embodiment can be threadedly connected to the reagent pipeline 32, or can be detachably installed in the reagent pipeline 32 by means of a buckle 35 or the like.

[0084] In addition, the check valve 20 of this embodiment is arranged in the water outlet pipe 11. The check valve 20 includes a valve seat 21, a valve stem 22 and a spring 23. The valve seat 21 is arranged in the water outlet pipe 11. An inlet communicating with the water outlet pipe 11 and an outlet communicating with the connecting pipe 38 are arranged on the valve seat 21. The valve stem 22 is telescopically arranged on the valve seat 21 through the spring 23. One end of the valve stem 22 blocks the inlet and is pressed tightly against the inlet by the acting force of the spring 23. Thus, the check valve 20 can block the inlet. When the water flow in the water outlet pipe 11 passes through the inlet of the valve seat 21, it can push open the valve stem 22 and make the water flow into the reagent cavity 31 of the reagent container 30 through the connecting pipe 38.

[0085] Therefore, when the oral cleaning device of this embodiment is in use, first, the nozzle 40 is disassembled from the reagent pipe 32, and reagent particles with nursing functions such as whitening and stain removal are put into the reagent pipe 32, and then the nozzle 40 is installed in the reagent pipe 32. Then, the main body 10 is started. The pump assembly 12 pumps the water in the water tank 13 into the water outlet pipe 11 to form a water flow. When the water flow passes through the check valve 20, it can push open the valve stem 22 and make the water flow into the reagent cavity 31 through the connecting pipe 38. At this time, the water flow is mixed and dissolved with the reagent particles in the reagent cavity 31 to form a reagent water flow. The reagent water flow is sprayed out from the reagent pipe 32, filtered through the filter screen 42 and then enters the nozzle 40, and finally shoots out from the ejection port 41 of the nozzle 40 into the user's oral cavity for cleaning and nursing.

[0086] Next, in conjunction with Figures 17 to 18 a specific embodiment of the oral cleaning device according to the present invention will be described in detail. It should be understood that the following is only a demonstration and should not be construed as a limitation of the present invention.

[0087] This embodiment provides an oral cleaning device, including a main body 10, a reagent container 30 and a nozzle 40. The main body 10 has a water outlet pipe 11; the reagent container 30 has a reagent cavity 31 and a reagent pipe 32. The reagent pipe 32 communicates with the reagent cavity 31. The reagent container 30 is connected to the water outlet pipe 11. A check valve 20 is arranged between the reagent container 30 and the water outlet pipe 11; the nozzle 40 has an ejection port 41, and the nozzle 40 is connected to the reagent container 30.

[0088] In this embodiment, the reagent container 30 is detachably connected to the housing. A groove 14 is formed by recessing the surface of the housing. The water outlet pipe 11 penetrates through the groove 14. The reagent container 30 is partially or entirely disposed in the groove 14. A connecting pipe 38 communicating with the reagent cavity 31 is provided on the reagent container 30. The connecting pipe 38 is detachably connected to the water outlet pipe 11. Thus, by partially or entirely disposing the reagent container 30 in the groove 14, the volume of the reagent container 30 exposed on the surface of the housing can be reduced, making the overall oral cleaning device more aesthetically pleasing.

[0089] Among them, the connecting pipe 38 can be threadedly connected to the water outlet pipe 11 or installed on the water outlet pipe 11 by means of a buckle 35 or the like. In addition, a filter screen 42 is provided between the nozzle 40 and the reagent container 30 in this embodiment. The filter screen 42 is disposed on the nozzle 40. A retaining frame 43 is detachably provided at one end of the nozzle 40 where it is connected to the reagent container 30, and the filter screen 42 is fixed in the nozzle 40 by the retaining frame 43. Further, the nozzle 40 in this embodiment can be threadedly connected to the reagent pipe 32 or detachably installed in the reagent pipe 32 by means of a buckle 35 or the like.

[0090] In addition, the check valve 20 in this embodiment is disposed in the water outlet pipe 11. The check valve 20 includes a valve seat 21, a valve rod 22, and a spring 23. The valve seat 21 is disposed in the water outlet pipe 11. An inlet communicating with the water outlet pipe 11 and an outlet communicating with the connecting pipe 38 are provided on the valve seat 21. The valve rod 22 is telescopically disposed on the valve seat 21 through the spring 23. One end of the valve rod 22 blocks the inlet, and is pressed tightly against the inlet by the acting force of the spring 23. Thus, the check valve 20 can block the inlet. When the water flow in the water outlet pipe 11 passes through the inlet of the valve seat 21, the valve rod 22 can be pushed open and the water flow can enter the reagent cavity 31 of the reagent container 30 through the connecting pipe 38.

[0091] Thus, when the oral cleaning device in this embodiment is in use, first, the nozzle 40 is detached from the reagent pipe 32, and reagent particles with nursing functions such as whitening and stain removal are put into the reagent pipe 32, then the nozzle 40 is installed in the reagent pipe 32. Then, the main body 10 is started, and the pump assembly 12 pumps the water in the water tank 13 into the water outlet pipe 11 to form a water flow. When the water flow passes through the check valve 20, the valve rod 22 can be pushed open and the water flow can enter the reagent cavity 31 through the connecting pipe 38. At this time, the water flow is mixed and dissolved with the reagent particles in the reagent cavity 31 to form a reagent water flow. The reagent water flow is ejected from the reagent pipe 32, filtered by the filter screen 42, enters the nozzle 40, and finally is ejected from the ejection port 41 of the nozzle 40 into the user's oral cavity for cleaning and nursing.

[0092] The following will be combined with Figures 19 to 20A specific embodiment of the oral cleaning device according to the present invention is described in detail. It should be understood that the following is only an illustrative description and should not be construed as a limitation of the present invention.

[0093] This embodiment provides an oral cleaning device, including a main body 10, a reagent container 30, and a nozzle 40. The main body 10 has a water outlet pipe 11; the reagent container 30 has a reagent cavity 31 and a reagent pipe 32. The reagent pipe 32 is communicated with the reagent cavity 31. The reagent container 30 is connected to the water outlet pipe 11, and a check valve 20 is provided between the reagent container 30 and the water outlet pipe 11; the nozzle 40 has a jet port 41, and the nozzle 40 is connected to the reagent container 30.

[0094] In this embodiment, the water outlet pipe 11 penetrates through the surface of the housing. The reagent container 30 is detachably connected to the housing, and the reagent container 30 is externally disposed on the housing. A connecting pipe 38 communicating with the reagent cavity 31 is provided on the reagent container 30, and the connecting pipe 38 is detachably connected to the water outlet pipe 11. Thus, by detachably installing the reagent container 30 on the water outlet pipe 11 and externally disposing the reagent container 30 on the housing, it is convenient to clean and replace the reagent container 30.

[0095] Among them, the connecting pipe 38 can be threadedly connected to the water outlet pipe 11 or installed on the water outlet pipe 11 by means of a buckle 35 or the like. In addition, a filter screen 42 is provided between the nozzle 40 and the reagent container 30 of this embodiment. The filter screen 42 is disposed on the nozzle 40. A retainer 43 is detachably provided at one end where the nozzle 40 is connected to the reagent container 30, and the filter screen 42 is fixed in the nozzle 40 by the retainer 43. Further, the connection between the nozzle 40 and the reagent pipe 32 in this embodiment includes but is not limited to threaded connection, snap connection, integral molding, etc., and the nozzle 40 is communicated with the reagent cavity 31; a reagent inlet communicating with the reagent cavity 31 is provided on the reagent container 30, and a lid 34 is provided on the reagent inlet. It can be understood that in these embodiments, the nozzle 40 and the reagent container 30 are provided as an integral structure. At this time, the reagent pipe 32 serves as a jet channel for the reagent water flow to supply the reagent water flow into the nozzle 40; while the reagent inlet serves as an input channel for the reagent particles, and the reagent inlet is hermetically sealed by the lid 34 to maintain the sealing performance of the reagent cavity 31.

[0096] In addition, the check valve 20 of this embodiment is disposed in the water outlet pipe 11. The check valve 20 includes a valve seat 21, a valve stem 22, and a spring 23. The valve seat 21 is disposed in the water outlet pipe 11. An inlet communicating with the water outlet pipe 11 and an outlet communicating with the connecting pipe 38 are provided on the valve seat 21. The valve stem 22 is telescopically disposed on the valve seat 21 through the spring 23. One end of the valve stem 22 blocks the inlet and is pressed tightly against the inlet by the acting force of the spring 23, so that the check valve 20 can block the inlet. When the water flow in the water outlet pipe 11 passes through the inlet of the valve seat 21, the valve stem 22 can be pushed open and the water flow can enter the reagent cavity 31 of the reagent container 30 through the connecting pipe 38.

[0097] Thus, when the oral cleaning device of this embodiment is in use, first open the lid 34 and put reagent particles with whitening, stain removal and other nursing functions into the reagent inlet, then cover the lid 34 to maintain the sealing of the reagent cavity 31, and then start the main body 10. The pump assembly 12 pumps the water in the water tank 13 into the water outlet pipe 11 to form a water flow. When the water flow passes through the check valve 20, the valve stem 22 can be pushed open and enter the reagent cavity 31. At this time, the water flow is mixed and dissolved with the reagent particles in the reagent cavity 31 to form a reagent water flow. The reagent water flow is ejected from the reagent pipe 32, filtered through the filter screen 42, and then enters the nozzle 40, and finally is ejected from the ejection port 41 of the nozzle 40 into the user's oral cavity for cleaning and nursing.

[0098] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the oral cleaning device of the invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
