[0028] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0029] As described in the background technology, the irrigating gun head on the oral irrigator is the component that directly contacts the oral cavity and sprays water. However, the existing irrigating gun heads are mostly fixed in design and lack the necessary protection mechanism. They are easily affected by external impact and extrusion during carrying, resulting in damage or deformation, which in turn affects the irrigating effect and safety.

[0030] In order to solve this technical problem, the utility model provides an oral irrigation gun, which is used for rinsing the oral cavity.

[0031] Specifically, please refer to Figures 1-4 , oral irrigation gun specifically includes:

[0032] The protective shell 1 has a liquid storage chamber 101, a conveying part is provided in the liquid storage chamber 101, the conveying part is connected to the second connecting tube 104, the inner wall of the second connecting tube 104 is rotatably connected to the third connecting tube 105, one end of the third connecting tube 105 passes through the protective shell 1 and is fixedly connected to the fourth connecting tube 106, and the fourth connecting tube 106 is connected to the nozzle 108.

[0033] The oral irrigation gun provided by the present invention adopts the rotatable design of the third connecting tube 105, so that the third connecting tube 105 can drive the fourth connecting tube 106 to rotate. When in use, the fourth connecting tube 106 can be erected to a suitable angle, so that the nozzle 108 can accurately rinse various parts of the oral cavity; when carrying it out, the irrigation gun head can be bent downward, significantly reducing the overall volume, making it easy to put it in a bag or suitcase, solving the problem of inconvenience in carrying traditional irrigation equipment. In addition, the bending design can also enable the protective shell 1 to play a certain protective role on the fourth connecting tube 106 and the nozzle 108, reducing the risk of damage and extending the service life of the product.

[0034] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0037] Example 1, please refer to Figures 1-4 An oral irrigation gun includes a protective shell 1, which has a liquid storage chamber 101. A delivery portion is provided in the liquid storage chamber 101, and the delivery portion is connected to a second connecting tube 104. The inner wall of the second connecting tube 104 is rotatably connected to a third connecting tube 105. One end of the third connecting tube 105 passes through the protective shell 1 and is fixedly connected to a fourth connecting tube 106. The fourth connecting tube 106 is connected to a nozzle 108. This design allows the fourth connecting tube 106 to be erected to a suitable angle when the irrigation gun is in use, making it easier for the nozzle 108 to accurately rinse various parts of the oral cavity, greatly improving the effect and convenience of the rinse. The user can easily adjust the angle of the nozzle 108 according to the needs of different positions of their own oral cavity to ensure that every corner can be fully cleaned. Because the third connecting tube 105 is rotatable, the angle of the nozzle 108 can be adjusted according to different parts of the oral cavity, so as to better rinse. When carrying it out, the fourth connecting tube 106 and the nozzle 108 can be rotated downward, which significantly reduces the overall volume and is convenient for putting into a bag or suitcase, solving the problem of the inconvenience of carrying traditional rinsing equipment. This allows users to conveniently carry the oral irrigator when traveling or on business trips, and keep their mouths clean at all times.

[0038] Furthermore, a sealed bearing is provided at the connection between the inner wall of the second connecting tube 104 and the third connecting tube 105, and the sealed bearing here is used to seal the connection between the second connecting tube 104 and the third connecting tube 105, and ensure that the two can rotate. A sealed bearing is also provided at the connection between the outer surface of the third connecting tube 105 and the protective shell 1, and the sealed bearing here is used to seal the connection between the second connecting tube 104 and the protective shell 1, and ensure that the two can rotate; the setting of the sealed bearing ensures the sealing of the connection, prevents liquid leakage, and ensures that the connecting tubes can rotate smoothly, which is crucial for the normal use of the product. If the connection is not sealed, liquid may leak from the connection, which will not only waste liquid resources, but also wet the surrounding environment, causing inconvenience to the user. The sealed bearing can not only play a sealing role, but also reduce friction during rotation, making the rotation between the connecting tubes smoother, thereby improving the use experience of the product.

[0039] Further, such as Figure 4As shown, a damping ring 109 is provided between the outer surface of the third connecting tube 105 and the side surface of the protective shell 1. The setting of the damping ring 109 allows the third connecting tube 105 to rotate or stay in the corresponding position, so as to adjust the angle of the nozzle 108 according to actual conditions, so that the user can adjust the angle of the nozzle 108 during use. This is very important for users when performing oral rinsing, because users can adjust the angle of the nozzle 108 according to their needs, and then rinse with confidence without having to worry about the angle of the nozzle 108 changing suddenly.

[0040] Example 2 further optimizes the oral irrigation gun provided in Example 1. Specifically, Figure 2 As shown, a thread is provided on the inner wall of the fourth connecting tube 106, and a threaded tube 107 is fixedly connected to the nozzle 108. The outer surface of the threaded tube 107 is threadedly connected to the inner wall of the fourth connecting tube 106, so that the nozzle 108 can be disassembled and replaced without replacing the entire flushing gun, saving the user's cost.

[0041] Further, such as Figure 1 As shown, the delivery part includes a delivery pump 102 installed in the liquid storage chamber 101, and the output end of the delivery pump 102 is connected to the first connecting pipe 103. The end of the first connecting pipe 103 away from the delivery pump 102 is fixedly connected to the second connecting pipe 104. The delivery pump 102 can deliver the liquid stored in the liquid storage chamber 101 to the second connecting pipe 104 through the first connecting pipe 103. The setting of the delivery pump 102 can provide a stable liquid delivery pressure, ensuring that the nozzle 108 can spray out enough liquid for flushing, thereby improving the flushing effect. The stable pressure can make the liquid spray out at an appropriate speed and force, so as to better clean the dirt and food residue in the oral cavity.

[0042] Further, such as Figure 1 As shown, a liquid adding tube 110 communicating with the liquid storage chamber 101 is provided on the top of the protective shell 1, and a protective cover 111 is threadedly connected to the outer surface of the liquid adding tube 110. A one-way valve 112 is provided in the middle of the protective cover 111. The one-way valve 112 is unidirectionally conducted into the liquid storage chamber 101, so that the air pressure in the liquid storage chamber 101 is maintained when the liquid in the liquid storage chamber 101 decreases.

[0043] Furthermore, a battery 113, a control main board 114 and a wireless charging module 115 are provided in the protective shell 1 below the liquid storage chamber 101. The delivery pump 102, the battery 113 and the wireless charging module 115 are all connected to the control main board 114. A control switch is also provided on the protective shell 1, and the control switch is connected to the control main board 114 for controlling the start and stop of the delivery pump 102.

[0044] Example 3, further optimizes the oral irrigation gun provided in Example 1 or 2, specifically, as Figure 5As shown, the outer surface of the protective shell 1 is provided with a protective mechanism 2, which includes two protective covers 201 provided on the outer surface of the protective shell 1. The two protective covers 201 are connected together by a damping hinge. The two protective covers 201 can protect the protective shell 1, the fourth connecting pipe 106, the nozzle 108 and other components, thereby further reducing damage during carrying.

[0045] The setting of the protective mechanism 2 can provide more comprehensive protection for the flushing gun during carrying and reduce the risk of damage. The protective cover 201 can effectively prevent the flushing gun from being bumped, squeezed and scratched during carrying, and protect the various parts of the flushing gun from damage. This is very important for users who often go out, because they can carry the flushing gun more confidently without having to worry about the flushing gun being damaged on the way.

[0046] Furthermore, a wireless charging base is provided in one of the protective covers 201, and the wireless charging base is used to cooperate with the wireless charging module 115 to charge the battery 113. Figure 6 During the charging process, the two protective covers 201 are rotated and arranged side by side. At this time, the contact area between the protective mechanism 2 and the supporting surface can be increased, thereby improving the stability of the protective mechanism 2 supporting the protective shell 1 during charging.

[0047] Further, such as Figure 6 As shown, magnets 202 are embedded in both protective covers 201. The magnets 202 can improve the stability of the connection between the two protective covers 201 when the two protective covers 201 protect the protective shell 1, reduce the risk of accidental opening of the protective covers 201 during carrying, and thus better protect the various components of the flushing gun.

[0048] The use process of the oral irrigation gun provided by the utility model is as follows:

[0049] Open the protective cover 111, add liquid, such as water, into the liquid storage chamber 101 through the liquid adding tube 110, then close the protective cover 111, rotate the fourth connecting tube 106 to rotate the third connecting tube 105, adjust the angle of the nozzle 108, and start the delivery pump 102. The delivery pump 102 delivers the water in the liquid storage chamber 101 to the nozzle 108 through the first connecting tube 103, the second connecting tube 104, the third connecting tube 105, and the fourth connecting tube 106. The water is then sprayed out from the nozzle 108 to rinse the oral cavity.

[0050] When carrying, rotate the two protective covers 201 to Figure 5 State, at this time, the magnets 202 are attracted together, the third connecting tube 105 is rotated to make the fourth connecting tube 106 rotate to the side of the protective shell 1, and then the protective shell 1 is placed between the two protective covers 201.
