Description

Technical Field

[0001] This utility model relates to the field of oral cleaning devices, and in particular to an oral cleaning device. Background Technology

[0002] Brushing teeth is the most common form of self-dental hygiene. While brushing effectively cleans the tooth surface that a toothbrush can reach, cleaning the areas between teeth and along the gum line, especially the gingival sulcus, requires other dental cleaning products. Therefore, a water flosser serves as a supplementary tool to a toothbrush, enabling the cleaning of areas difficult to reach with a toothbrush, such as between teeth and the gingival sulcus.

[0003] A typical oral irrigator consists of a housing, a water tank, a water pump, and a nozzle. The water pump's inlet connects to the water tank, and the water pump's outlet connects to the nozzle. The water jet from the nozzle cleans food debris and residue from between teeth, thus protecting dental health. However, most oral irrigators on the market currently only have a rinsing function and lack further oral care features (such as teeth whitening, breath freshening, and gum inflammation reduction). Utility Model Content

[0004] Therefore, the purpose of this utility model is to overcome the shortcomings of the prior art and provide an oral cleaning device that cleans and cares for the user's oral cavity by adding reagent particles with care function to the reagent container and spraying reagent water through the matching nozzle, thereby improving the ability to clean the oral cavity.

[0005] To achieve the above objectives, this utility model provides an oral cleaning device, comprising:

[0006] The main body has a water outlet pipe;

[0007] A reagent container has a reagent cavity and a reagent pipeline, the reagent pipeline being connected to the reagent cavity, the reagent container being connected to the water outlet pipeline, and a check valve being provided between the reagent container and the water outlet pipeline;

[0008] A nozzle having a spray nozzle is connected to the reagent container.

[0009] Therefore, the oral cleaning device according to this utility model embodiment, by setting a reagent container between the main body and the nozzle, allows for the addition of nursing-functional reagent particles into the reagent cavity through a reagent pipe. The main body then supplies water to the outlet pipe. The water flows through a check valve into the reagent cavity of the reagent container, where it mixes and dissolves with the reagent particles to form a reagent water flow. This reagent water flow then enters the nozzle and is finally ejected through the nozzle's spray nozzle into the user's mouth for cleaning and nursing. The check valve prevents the reagent water from flowing back into the outlet pipe, effectively preventing contamination of the main body. In other words, the oral cleaning device according to this utility model embodiment, by adding reagent particles to the reagent container, facilitates oral cleaning and nursing.

[0010] In one embodiment, the main body includes a housing, a water tank, and a pump assembly. The water tank and the pump assembly are respectively disposed in the housing. The pump assembly is connected to the water tank and the outlet pipe respectively, and the pump assembly is used to pump the liquid in the water tank into the outlet pipe.

[0011] In one embodiment, a filter screen is provided between the nozzle's spray port and the reagent container. This filters the reagent water flow, effectively preventing small dissolved reagent particles from entering the nozzle and improving the user experience.

[0012] In one embodiment, the reagent container is fixedly disposed inside the housing, the reagent conduit penetrates the surface of the housing, and the nozzle is detachably connected to the reagent conduit. Thus, by detachably installing the nozzle to the reagent conduit, it facilitates nozzle cleaning and replacement without hindering the addition of reagent particles.

[0013] In one embodiment, the reagent container is provided with a rinsing pipe communicating with the reagent cavity. The rinsing pipe penetrates the surface of the housing, and the nozzle is detachably connected to the rinsing pipe. Therefore, by detachably installing the nozzle to the rinsing pipe, cleaning and replacement of the nozzle can be facilitated.

[0014] In one embodiment, the reagent tubing extends through the surface of the housing and is detachably connected to a cap.

[0015] In one embodiment, the water outlet pipe penetrates the surface of the housing, and the reagent container is detachably connected to the housing. The reagent container is provided with a connecting pipe communicating with the reagent cavity, and this connecting pipe is detachably connected to the water outlet pipe. Therefore, by detachably installing the reagent container onto the water outlet pipe, cleaning and replacement of the reagent container can be easily facilitated.

[0016] In one embodiment, the surface of the housing is recessed to form a groove, through which the water outlet pipe passes, and the reagent container is partially or entirely disposed within the groove. Therefore, by placing the reagent container partially or entirely within the groove, the volume of the reagent container protruding from the housing surface can be reduced, making the overall oral cleaning device more aesthetically pleasing.

[0017] In one embodiment, the nozzle is detachably connected to the reagent pipeline, and the nozzle communicates with the reagent cavity. Therefore, by detachably installing the nozzle onto the reagent pipeline, it facilitates nozzle cleaning and replacement without hindering the addition of reagent particles.

[0018] In one embodiment, the nozzle is fixedly connected to the reagent pipeline and communicates with the reagent cavity; the reagent container and / or the nozzle are provided with a reagent inlet communicating with the reagent cavity, and a cover is provided on the reagent inlet.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0044] In the following description, when referring to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first," "second," "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0045] Brushing teeth is the most common self-care practice for dental hygiene. While brushing cleans the areas of the teeth that a toothbrush can reach, cleaning the surfaces between teeth, especially the gum line, requires other dental hygiene products. Therefore, a water flosser serves as an auxiliary tool to toothbrushes, cleaning areas that are difficult to reach with a brush, such as between teeth and the gum line. A water flosser typically consists of a casing, a water tank, a water pump, and a nozzle. The water pump's inlet connects to the water tank, and the outlet connects to the nozzle. The water jet from the nozzle washes away food debris and debris from between teeth, thus protecting dental health. However, most water flossers on the market currently only have a rinsing function and lack further oral care features (such as teeth whitening, breath freshening, and gum inflammation reduction).

[0046] In view of this, the present invention provides an oral cleaning device that cleans and cares for the user's oral cavity by adding reagent particles with care function to a reagent container and spraying reagent water through a matching nozzle, thereby improving the ability to clean the oral cavity.

[0047] Please see Figures 1 to 4 This utility model provides an oral cleaning device, comprising:

[0048] The main body 10 has a water outlet pipe 11;

[0049] The reagent container 30 has a reagent cavity 31 and a reagent pipe 32. The reagent pipe 32 is connected to the reagent cavity 31. The reagent container 30 is connected to the water outlet pipe 11. A check valve 20 is provided between the reagent container 30 and the water outlet pipe 11.

[0050] Nozzle 40 has a spray port 41 and is connected to reagent container 30.

[0051] Therefore, according to the oral cleaning device of this utility model, by setting a reagent container 30 between the main body 10 and the nozzle 40, reagent particles with a nursing function are added to the reagent cavity 31 through the reagent pipe 32, and water is supplied to the water outlet pipe 11 by the main body 10. The water flows into the reagent cavity 31 of the reagent container 30 after passing through the check valve 20, and mixes and dissolves 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 exits through the spray port 41 of the nozzle 40 and enters the user's mouth to clean and care for the user's mouth. 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. In other words, the oral cleaning device according to the embodiment of this utility model, by adding reagent particles to the reagent container 30, facilitates the oral cleaning device to clean and care for the mouth.

[0052] like Figure 3 and Figure 4 As shown, the main body 10 of this utility model includes a shell, a water tank 13, and a pump assembly 12. The water tank 13 and the pump assembly 12 are respectively disposed in the shell. The pump assembly 12 is connected to the water tank 13 and the water outlet pipe 11 respectively, and the pump assembly 12 is used to pump the liquid in the water tank 13 into the water outlet pipe 11.

[0053] In this invention, the water tank 13 has a water inlet extending through the side wall of the housing, connecting to the interior of the water tank 13. A water cap is provided over the water inlet, allowing the user to inject water into the water tank 13 through the inlet. Furthermore, the housing contains a control circuit board for starting or stopping the pump assembly 12, and a battery for increasing the power of the pump assembly 12 is also located within the housing. A switch button is provided on the surface of the housing for user operation of the main body 10.

[0054] In this invention, a filter screen 42 is provided between the spray port 41 of the nozzle 40 and the reagent container 30. Thus, by filtering the reagent water stream through the filter screen 42, small particles of reagent dissolved in the reagent water stream can be effectively prevented from entering the nozzle 40, thereby significantly improving the user experience.

[0055] like Figure 5 As shown, in some embodiments of this utility model, 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 an inlet connected to the water outlet pipe 11 and an outlet connected to the reagent cavity 31. The valve stem 22 is telescopically disposed on the valve seat 21 by the spring 23, and one end of the valve stem 22 is sealed on the water inlet and pressed against the water inlet by the force of the spring 23. Thus, the check valve 20 can block the water inlet. When water is sprayed out of the water outlet pipe 11, the valve stem 22 can be opened and the water can enter the reagent cavity 31 of the reagent container 30.

[0056] like Figure 6 As shown, in some embodiments of this utility model, 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 an inlet connected to the water outlet pipe 11 and an outlet connected to the connecting pipe 38. The valve stem 22 is telescopically disposed on the valve seat 21 by the spring 23, and one end of the valve stem 22 is sealed on the inlet. The spring 23 is used to press against the inlet, thereby enabling the check valve 20 to block the inlet. When the water flow in the water outlet pipe 11 passes through the inlet of the valve seat 21, it can open the valve stem 22 and 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 assembly 12 pumps the water in the water tank 13 into the water outlet pipe 11 and forms a water flow. The water flow can open the check valve 20 and enter the reagent chamber 31. At this time, the water flow mixes and dissolves 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. Finally, it is ejected from the spray port 41 of the nozzle 40 and enters the user's mouth for cleaning and care.

[0058] like Figures 7 to 9As shown, the filter screen 42 of this invention can be disposed at the end of the nozzle 40 away from the spray port 41. A retainer 43 is detachably disposed at the end of the nozzle 40 connected to the reagent container 30, and the filter screen 42 is fixed in the nozzle 40 by the retainer 43. In this way, the reagent water flow can be filtered through the filter screen 42, and the retainer 43 can be easily disassembled for cleaning or replacement of the filter screen 42. In addition, in some other embodiments, the filter screen 42 can also be disposed in the reagent container 30.

[0059] Optionally, in some embodiments of this utility model, the reagent container 30 is fixedly disposed inside the shell, the reagent pipe 32 penetrates the surface of the shell, and the nozzle 40 is detachably connected to the reagent pipe 32. Thus, by detachably installing the nozzle 40 to the reagent pipe 32, it is convenient to clean and replace the nozzle 40 without hindering the addition of reagent particles; furthermore, by using the reagent pipe 32 as a connection channel for the nozzle 40, the reagent pipe 32 can serve as both a channel for adding reagent particles and a channel for spraying reagent water, eliminating the need for an additional pipe connected to the nozzle 40 on the reagent container 30.

[0060] In these embodiments, one end of the nozzle 40 may be threaded into the reagent tubing 32, or detachably installed into the reagent tubing 32 via a snap-fit ​​35 or similar means. Furthermore, to improve the sealing between the nozzle 40 and the reagent tubing 32, a waterproof sealing ring 36 may be provided between them, thereby enhancing the seal.

[0061] Optionally, in some embodiments of this utility model, the reagent container 30 is fixedly disposed inside the shell, and the reagent container 30 is provided with a rinsing pipe 37 communicating with the reagent cavity 31. The rinsing pipe 37 penetrates the surface of the shell, and the nozzle 40 is detachably connected to the rinsing pipe 37. Thus, by detachably installing the nozzle 40 to the rinsing pipe 37, the cleaning and replacement of the nozzle 40 can be facilitated. The reagent pipe 32 penetrates the surface of the shell, and the reagent pipe 32 is detachably connected to a cover 34.

[0062] In these embodiments, one end of the nozzle 40 may be threaded into the rinsing pipe 37, or detachably installed into the rinsing pipe 37 via a snap-fit ​​35 or similar means. To improve the sealing between the nozzle 40 and the rinsing pipe 37, a waterproof sealing ring 36 may be provided between the nozzle 40 and the rinsing pipe 37, thereby improving the sealing between the two. Furthermore, the sealing of the reagent pipe 32 can be improved by providing a cap 34 on the reagent pipe 32. It can be understood that in these embodiments, the reagent pipe 32 serves as the channel for introducing reagent particles, and the rinsing pipe 37 serves as the outlet pipe connecting the nozzle 40, allowing reagent water to be sprayed out and enter the nozzle 40.

[0063] Optionally, in some embodiments of this utility model, the water outlet pipe 11 penetrates the surface of the shell, the reagent container 30 is detachably connected to the shell, and the reagent container 30 is provided with a connecting pipe 38 communicating with the reagent cavity 31, the connecting pipe 38 being detachably connected to the water outlet pipe 11. Thus, by detachably installing the reagent container 30 onto the water outlet pipe 11 and placing the reagent container 30 externally on the shell, it is convenient to clean and replace the reagent container 30.

[0064] In these embodiments, one end of the nozzle 40 can be threaded into the reagent pipe 32, or detachably installed into the reagent pipe 32 via a snap-fit ​​35 or similar means. That is, by using the reagent pipe 32 as the connection channel for the nozzle 40, the reagent pipe 32 can serve as both a channel for introducing reagent particles and a channel for discharging reagent water, eliminating the need for an additional pipe connected to the nozzle 40 on the reagent container 30. Furthermore, to improve the sealing between the nozzle 40 and the reagent pipe 32, a waterproof sealing ring 36 can be provided between them, thereby enhancing the airtightness.

[0065] Optionally, in some embodiments of this utility model, the reagent container 30 is detachably connected to the shell, and a groove 14 is formed on the surface of the shell. The water outlet pipe 11 passes through the groove 14, and 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, and the connecting pipe 38 is detachably connected to the water outlet pipe 11. Therefore, by partially or entirely disposing of the reagent container 30 in the groove 14, the volume of the reagent container 30 exposed on the shell surface can be reduced, making the overall oral cleaning device more aesthetically pleasing.

[0066] In these embodiments, one end of the nozzle 40 can be threaded into the reagent pipe 32, or detachably installed into the reagent pipe 32 via a snap-fit ​​35 or similar means. That is, by using the reagent pipe 32 as the connection channel for the nozzle 40, the reagent pipe 32 can serve as both a channel for introducing reagent particles and a channel for discharging reagent water, eliminating the need for an additional pipe connected to the nozzle 40 on the reagent container 30. Furthermore, to improve the sealing between the nozzle 40 and the reagent pipe 32, a waterproof sealing ring 36 can be provided between them, thereby enhancing the airtightness.

[0067] Optionally, in some embodiments of this utility model, the water outlet pipe 11 penetrates the surface of the shell, the reagent container 30 is detachably connected to the shell, and the reagent container 30 is provided with a connecting pipe 38 communicating with the reagent cavity 31, the connecting pipe 38 being detachably connected to the water outlet pipe 11. Thus, by detachably installing the reagent container 30 onto the water outlet pipe 11 and placing the reagent container 30 externally on the shell, it is convenient to clean and replace the reagent container 30.

[0068] In these embodiments, the nozzle 40 is connected to the reagent pipeline 32 and communicates with the reagent cavity 31; the reagent container 30 and / or the nozzle 40 have a reagent inlet 33 communicating with the reagent cavity 31, and a cover 34 is provided on the reagent inlet 33. That is, in these embodiments, the nozzle 40 and the reagent container 30 are set as an integral structure, and the nozzle 40 and the reagent container 30 are fixedly connected. In this case, the reagent pipeline 32 serves as the outlet channel for the reagent water flow, allowing the reagent water flow into the nozzle 40; while the reagent inlet 33 serves as the inlet channel for the reagent particles, and the cover 34 is used to seal the reagent inlet 33 to maintain the airtightness of the reagent cavity 31. The connection between the reagent container 30 and the nozzle 40 includes, but is not limited to, snap-fit ​​connection, threaded connection, and integral molding.

[0069] like Figure 10 As shown, in some embodiments of this utility model, the reagent container 30 and the nozzle 40 are connected together by a threaded connection, and a waterproof sealing ring 36 is provided between the nozzle 40 and the reagent container 30. A reagent inlet 33 for adding reagent particles is provided on the reagent container 30, and a cover 34 is detachably connected to the reagent inlet 33.

[0070] The following is combined Figures 11 to 12 The following is a detailed description of a specific embodiment of the oral cleaning device according to the present invention. It is worth understanding that the following is merely an illustrative description and should not be construed as limiting the present invention.

[0071] This embodiment provides an oral cleaning device, including a body 10, a reagent container 30, and a nozzle 40. The 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 connected to 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 spray port 41 and is connected to the reagent container 30. The reagent container 30 is fixedly disposed 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 shell, a water tank 13, and a pump assembly 12. The water tank 13 and the pump assembly 12 are respectively disposed in the shell. The pump assembly 12 is connected to the water tank 13 and the water outlet pipe 11, and is used to pump the liquid in the water tank 13 into the water outlet pipe 11. Furthermore, in this embodiment, a filter screen 42 is disposed between the nozzle 40 and the reagent container 30. The filter screen 42 is disposed on the nozzle 40, and a retainer 43 is detachably disposed at the end of the nozzle 40 connected to the reagent container 30, and the filter screen 42 is fixed in the nozzle 40 by the retainer 43. Further, in this embodiment, the nozzle 40 can be threaded into the reagent pipe 32, or detachably installed in the reagent pipe 32 by means of a snap-fit ​​35 or other means.

[0073] Furthermore, in this embodiment, 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 an inlet connected to the water outlet pipe 11 and an outlet connected to the reagent cavity 31. The valve stem 22 is telescopically disposed on the valve seat 21 by the spring 23, and one end of the valve stem 22 is sealed on the water inlet and pressed against the water inlet by the force of the spring 23. Thus, the check valve 20 can block the water inlet. When water is sprayed out of the water outlet pipe 11, the valve stem 22 can be opened and the water can enter the reagent cavity 31 of the reagent container 30.

[0074] Therefore, when using the oral cleaning device of this embodiment, the nozzle 40 is first removed from the reagent pipe 32, and reagent particles with whitening, stain removal and other care functions are added 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, it can push the valve stem 22 open and enter the reagent chamber 31. At this time, the water flow mixes and dissolves with the reagent particles in the reagent chamber 31 to form a reagent water flow. The reagent water flow is sprayed out from the reagent pipe 32 and filtered by the filter screen 42 before entering the nozzle 40. Finally, it is ejected from the spray port 41 of the nozzle 40 and enters the user's oral cavity for cleaning and care.

[0075] The following is combined Figures 13 to 14 The following is a detailed description of a specific embodiment of the oral cleaning device according to the present invention. It is worth understanding that the following is merely an illustrative description and should not be construed as limiting the present invention.

The pump assembly 12 is connected to the water tank 13 and the water outlet pipe 11, and is used to pump the liquid in the water tank 13 into the water outlet pipe 11. Furthermore, in this embodiment, a filter screen 42 is disposed between the nozzle 40 and the reagent container 30. The filter screen 42 is disposed on the nozzle 40, and a retainer 43 is detachably disposed at the end of the nozzle 40 connected to the reagent container 30, and the filter screen 42 is fixed in the nozzle 40 by the retainer 43. Further, in this embodiment, the nozzle 40 can be threaded into the reagent pipe 32, or detachably installed in the reagent pipe 32 by means of a snap-fit ​​35 or other means.

[0078] Furthermore, in this embodiment, 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 stem 22 is telescopically disposed on the valve seat 21 by the spring 23, and one end of the valve stem 22 is sealed on the water inlet and pressed against the water inlet by the force of the spring 23. Thus, the check valve 20 can block the water inlet. When water is sprayed out of the water outlet pipe 11, the valve stem 22 can be opened and the water can enter the reagent cavity 31 of the reagent container 30.

[0079] Therefore, when using the oral cleaning device of this embodiment, firstly, reagent particles with whitening, stain removal and other care functions are added to the reagent pipe 32, and then the lid 34 is closed to seal 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, it can push the valve stem 22 open and enter the reagent chamber 31. At this time, the water flow mixes and dissolves with the reagent particles in the reagent chamber 31 to form a reagent water flow. The reagent water flow is sprayed out from the rinsing pipe 37 and filtered by the filter screen 42 before entering the nozzle 40. Finally, it is ejected from the spray port 41 of the nozzle 40 and enters the user's oral cavity for cleaning and care.

[0080] The following is combined Figures 15 to 16 The following is a detailed description of a specific embodiment of the oral cleaning device according to the present invention. It is worth understanding that the following is merely an illustrative description and should not be construed as limiting the present invention.

[0081] This embodiment provides an oral cleaning device, including a body 10, a reagent container 30, and a nozzle 40. The 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 connected to 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 spray port 41 and is connected to the reagent container 30.

[0082] In this embodiment, the water outlet pipe 11 penetrates the surface of the housing, the reagent container 30 is detachably connected to the housing, and the reagent container 30 is placed externally on the housing. The reagent container 30 is provided with a connecting pipe 38 that communicates with the reagent cavity 31, and the connecting pipe 38 is detachably connected to the water outlet pipe 11. Therefore, by detachably installing the reagent container 30 on the water outlet pipe 11 and placing the reagent container 30 externally on the housing, it is convenient to clean and replace the reagent container 30.

[0083] The connecting pipe 38 can be threaded into the water outlet pipe 11 or installed on the water outlet pipe 11 using a snap-fit ​​35 or similar method. Furthermore, in this embodiment, a filter screen 42 is provided between the nozzle 40 and the reagent container 30. The filter screen 42 is disposed on the nozzle 40, and a retainer 43 is detachably provided at the end of the nozzle 40 connected to the reagent container 30, thereby fixing the filter screen 42 in the nozzle 40. Further, in this embodiment, the nozzle 40 can be threaded into the reagent pipe 32 or detachably installed in the reagent pipe 32 using a snap-fit ​​35 or similar method.

[0084] Furthermore, in this embodiment, 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 and has an inlet connected to the water outlet pipe 11 and an outlet connected to the connecting pipe 38. The valve stem 22 is retractably disposed on the valve seat 21 by the spring 23, and one end of the valve stem 22 is sealed on the inlet and pressed against the inlet by the 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 allow the water flow to enter the reagent cavity 31 of the reagent container 30 through the connecting pipe 38.

[0085] Therefore, when using the oral cleaning device of this embodiment, the nozzle 40 is first removed from the reagent pipe 32, and reagent particles with whitening, stain removal and other care functions are added to 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, it can open the valve stem 22 and allow the water flow to enter the reagent chamber 31 through the connecting pipe 38. At this time, the water flow mixes and dissolves with the reagent particles in the reagent chamber 31 to form a reagent water flow. The reagent water flow is sprayed out from the reagent pipe 32 and filtered by the filter screen 42 before entering the nozzle 40. Finally, it is ejected from the spray port 41 of the nozzle 40 and enters the user's oral cavity for cleaning and care.

[0086] The following is combined Figures 17 to 18 The following is a detailed description of a specific embodiment of the oral cleaning device according to the present invention. It is worth understanding that the following is merely an illustrative description and should not be construed as limiting the present invention.

[0087] This embodiment provides an oral cleaning device, including a body 10, a reagent container 30, and a nozzle 40. The 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 connected to 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 spray port 41 and is connected to the reagent container 30.

[0088] In this embodiment, the reagent container 30 is detachably connected to the shell. A groove 14 is formed on the surface of the shell, through which the water outlet pipe 11 passes. The reagent container 30 is partially or entirely disposed within the groove 14, and 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. Therefore, by partially or entirely disposing of the reagent container 30 within the groove 14, the volume of the reagent container 30 exposed on the shell surface is reduced, resulting in a more aesthetically pleasing overall appearance of the oral cleaning device.

[0089] The connecting pipe 38 can be threaded into the water outlet pipe 11 or installed on the water outlet pipe 11 using a snap-fit ​​35 or similar method. Furthermore, in this embodiment, a filter screen 42 is provided between the nozzle 40 and the reagent container 30. The filter screen 42 is disposed on the nozzle 40, and a retainer 43 is detachably provided at the end of the nozzle 40 connected to the reagent container 30, thereby fixing the filter screen 42 in the nozzle 40. Further, in this embodiment, the nozzle 40 can be threaded into the reagent pipe 32 or detachably installed in the reagent pipe 32 using a snap-fit ​​35 or similar method.

[0090] Furthermore, in this embodiment, 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 and has an inlet connected to the water outlet pipe 11 and an outlet connected to the connecting pipe 38. The valve stem 22 is retractably disposed on the valve seat 21 by the spring 23, and one end of the valve stem 22 is sealed on the inlet and pressed against the inlet by the 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 allow the water flow to enter the reagent cavity 31 of the reagent container 30 through the connecting pipe 38.

[0091] Therefore, when using the oral cleaning device of this embodiment, the nozzle 40 is first removed from the reagent pipe 32, and reagent particles with whitening, stain removal and other care functions are added to 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, it can open the valve stem 22 and allow the water flow to enter the reagent chamber 31 through the connecting pipe 38. At this time, the water flow mixes and dissolves with the reagent particles in the reagent chamber 31 to form a reagent water flow. The reagent water flow is sprayed out from the reagent pipe 32 and filtered by the filter screen 42 before entering the nozzle 40. Finally, it is ejected from the spray port 41 of the nozzle 40 and enters the user's oral cavity for cleaning and care.

[0092] The following is combined Figures 19 to 20The following is a detailed description of a specific embodiment of the oral cleaning device according to the present invention. It is worth understanding that the following is merely an illustrative description and should not be construed as limiting the present invention.

[0093] This embodiment provides an oral cleaning device, including a body 10, a reagent container 30, and a nozzle 40. The 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 connected to 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 spray port 41 and is connected to the reagent container 30.

[0094] In this embodiment, the water outlet pipe 11 penetrates the surface of the housing, the reagent container 30 is detachably connected to the housing, and the reagent container 30 is placed externally on the housing. The reagent container 30 is provided with a connecting pipe 38 that communicates with the reagent cavity 31, and the connecting pipe 38 is detachably connected to the water outlet pipe 11. Therefore, by detachably installing the reagent container 30 on the water outlet pipe 11 and placing the reagent container 30 externally on the housing, it is convenient to clean and replace the reagent container 30.

[0095] The connecting pipe 38 can be threaded into the water outlet pipe 11 or installed on the water outlet pipe 11 using a snap-fit ​​35 or similar method. Furthermore, in this embodiment, a filter screen 42 is provided between the nozzle 40 and the reagent container 30. The filter screen 42 is disposed on the nozzle 40, and a retainer 43 is detachably provided at the end of the nozzle 40 connected to the reagent container 30, thereby fixing the filter screen 42 in the nozzle 40. Further, the connection between the nozzle 40 and the reagent pipe 32 in this embodiment includes, but is not limited to, threaded connection, snap-fit ​​connection, and integral molding, and the nozzle 40 is connected to the reagent cavity 31; the reagent container 30 has a reagent inlet communicating with the reagent cavity 31, and a cover 34 is provided on the reagent inlet. It can be understood that in these embodiments, the nozzle 40 and the reagent container 30 are set as an integral structure. At this time, the reagent pipe 32 serves as the spray channel for the reagent water to enter the nozzle 40; while the reagent inlet serves as the input channel for the reagent particles, and the reagent inlet is sealed with a cover 34 to maintain the airtightness of the reagent cavity 31.

[0096] Furthermore, in this embodiment, 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 and has an inlet connected to the water outlet pipe 11 and an outlet connected to the connecting pipe 38. The valve stem 22 is retractably disposed on the valve seat 21 by the spring 23, and one end of the valve stem 22 is sealed on the inlet and pressed against the inlet by the 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 allow the water flow to enter the reagent cavity 31 of the reagent container 30 through the connecting pipe 38.

[0097] Therefore, when using the oral cleaning device of this embodiment, first open the cover 34 and put the reagent particles with whitening, stain removal and other care functions into the reagent inlet, then close the cover 34 to maintain the sealing of the reagent cavity 31. Then start the main body 10, 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, it can push the valve stem 22 open and enter the reagent cavity 31. At this time, the water flow mixes and dissolves 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 and filtered by the filter screen 42 before entering the nozzle 40. Finally, it is ejected from the spray port 41 of the nozzle 40 and enters the user's mouth for cleaning and care.

It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
