Among them, the liquid storage member is used to store liquid, the water path assembly is used to transport the liquid in the liquid storage member to the water pipe, and the circuit board is used to control the start, stop, and power of the water path assembly. Since mechanical connection cannot achieve complete sealing, liquid leakage may occur in components containing liquid such as the water path assembly and the liquid storage member. In the existing rinser, after the water path assembly or the liquid storage member leaks, the liquid will naturally flow to the space where circuit components such as the circuit board are located, thereby causing damage to the circuit board.

Detailed implementation manners

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs; the terms used in the description of the present application in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and are not used to describe a specific order.

[0035] References herein to "embodiments" mean that the particular features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0036] Please refer to Figures 1 to 2 , where the Z direction in the figure is the up and down direction, and the X is the left and right direction. An embodiment of the present invention provides a rinser 10 for storing and delivering liquid to a handle 40. The rinser 10 includes:

[0037] A housing 100 provided with a receiving cavity;

[0038] A partition plate 400 located in the receiving cavity and dividing the receiving cavity into a first sub-receiving cavity 110 and a second sub-receiving cavity 120;

[0039] A liquid storage member 200 connected to the housing 100 for storing liquid;

[0040] A waterway structure located in the first sub-receiving cavity 110 and connected to the liquid storage member 200;

[0041] A circuit board 600 located in the second sub-receiving cavity 120 and controlling the waterway structure to deliver liquid to the handle.

[0042] In this embodiment, please refer to Figures 1 to 2 , since the partition plate 400 divides the receiving cavity into a first sub-receiving cavity 110 and a second sub-receiving cavity 120. At this time, if there is a liquid leakage phenomenon in the waterway structure, the partition plate 400 can play a role in isolating the liquid from entering the circuit board 600, thereby avoiding the short circuit of the circuit board 600 and improving the service life of the rinser 10.

[0043] It should be understood that when the partition plate 400 is placed horizontally (placed along the Figure 1 X direction in

[0044] Therefore, the partition 400 in the embodiment of the present application can be vertically placed (such as Figure 1 prevented in the Z direction in

[0045] ). At this time, the first sub-accommodation cavity 110 and the second sub-accommodation cavity 120 formed by the partition 400 are respectively located in the left-right direction. At this time, the water flow cannot flow into the second sub-accommodation cavity 120 under the action of gravity. Therefore, the service life of the flusher 10 is further improved. Figures 1 to 2 Furthermore, please refer to Figure 1 for the upper surface ( Figure 1 the outer upper surface in

[0046] ), and the lower surface (

[0047] the outer lower surface in

[0048] ). The partition plate 400 is disposed perpendicular to the upper surface and the lower surface. The liquid storage member 200 is connected to the upper surface and is located outside the accommodation cavity. Moreover, the projection of the liquid storage member 200 on the upper surface is within the projection range of the first sub-accommodation cavity 110 on the upper surface.

[0049] In this embodiment, if the liquid storage member 200 is connected to the side surface of the housing 100, the flusher 10 will occupy a relatively large area on the horizontal plane. At this time, the floor area of the flusher 10 is relatively large, which is not conducive to placement. The liquid storage member 200 in this embodiment is disposed on the upper surface of the housing 100, so that the floor area of the flusher 10 can be effectively reduced. Figures 1 to 2 At the same time, since the projection of the liquid storage member 200 on the upper surface is within the projection range of the first sub-accommodation cavity 110 on the upper surface, even if the connection between the liquid storage member 200 and the housing 100 leaks, the leaked liquid will enter the first sub-accommodation cavity 110. The first sub-accommodation cavity 110 and the second sub-accommodation cavity 120 are separated by the partition 400, so this part of the leaked liquid cannot affect the circuit board 600.

[0050] In summary, the flusher 10 in this embodiment has a small floor area and a long service life.

[0051] It can be understood that another through hole can also be provided in the second sub-accommodating cavity 120. At this time, this through hole can prevent the liquid from penetrating into the second sub-accommodating cavity 120 and volatilizing to form a humid environment, which may affect the circuit board 600.

[0052] Further, please refer to Figures 1 to 3 , the rinser 10 further includes a tail pipe 30 and a limiting member 20. The limiting member 20 is provided with an annular groove 23 and is disposed through the housing 100. One end is located inside the housing 100 and the other end is located outside the housing 100. At least a part of the housing 100 is clamped in the annular groove 23. The tail pipe 30 is disposed through the limiting member 20 and is in interference fit with the limiting member 20.

[0053] Generally, the rinser 10 also needs to be connected to a water pipe and a handle. At this time, the water pipe needs to be connected to a water path structure, and the water path structure transports the liquid to the handle through the water pipe. In the rinser 10 of the prior art, after the water pipe is connected, liquid leakage is likely to occur at the connection between the water pipe and the rinser 10.

[0054] In this embodiment, the tail pipe 30 is disposed through the limiting member 20 in interference fit. Therefore, when the tail pipe 30 is installed, it only needs to be deformed by extrusion to pass through the limiting member 20 to complete its own fixation. Therefore, the installation efficiency of the rinser 10 is high. When the water pipe is inside the tail pipe 30, the tail pipe 30 can play a role in protecting the water pipe; at the same time, the limiting member 20 is disposed through the housing 100, and the housing 100 is clamped in the annular groove 23. Therefore, due to the limiting effect of the annular groove 23, the limiting member 20 cannot move away from the housing 100.

[0055] In summary, the tail pipe 30 can play a role in protecting the water pipe and guiding the water pipe into the interior of the housing 100. At the same time, since the contact area between the water pipe and the tail pipe 30 is relatively large, and one end of the tail pipe 30 can extend beyond the bottom surface of the accommodating cavity, it is difficult for the liquid to overflow along the water pipe from the gap between the water pipe and the tail pipe 30. In summary, the rinser 10 of this embodiment has high installation efficiency, strong stability, and high sealing performance.

[0056] Further, please refer to Figures 1 to 3 , the housing 100 is provided with a mounting hole (not marked in the figure). The limiting member 20 is disposed through the mounting hole. The mounting hole is in interference fit with the limiting member, and the limiting member 20 is an elastic member.

[0057] In this embodiment, since the limiting member 20 is an elastic member, it has elasticity and can pass through the mounting hole provided on the housing 100 through slight deformation, thereby completing its own installation. At the same time, it can also avoid rigid contact between the tail pipe 30 and the housing 100 through elastic deformation, thereby preventing the tail pipe 30 from being damaged under the action of rigid friction after being pulled.

[0058] Further, please refer to Figures 1 to 3, along the direction away from the accommodation cavity, a first annular protrusion 21 and a second annular protrusion 22 are sequentially arranged on the side wall of the limiting member 20, and an annular groove 23 is formed between the first annular protrusion 21 and the second annular protrusion 22;

[0059] Wherein, the first annular protrusion 23 is provided with a guiding arc surface 24, and the guiding arc surface 24 arches towards the accommodation cavity.

[0060] In this embodiment, the guiding arc surface 24 can play a role in guiding the limiting member 20 to pass through the housing 100. That is, holes can be provided on the housing 100. When the tail pipe 30 guiding member passes through the housing 100, the holes can first contact the upper surface of the guiding arc surface 24, and then as the tail pipe 30 guiding member gradually penetrates into the housing 100, the tail pipe 30 guiding member gradually deforms so that the first annular protrusion 21 passes through the holes. During this process, the guiding arc surface 24 can make the force on the limiting member 20 increase smoothly, thereby avoiding excessive force and damage when the first annular protrusion 21 passes through the holes.

[0061] Furthermore, please refer to Figures 1 to 3 , the partition plate 400 is provided with a first through hole (not shown in the figure) and a second through hole (not shown in the figure). The flusher 10 further includes a cable tie (not shown in the figure). The cable tie passes through the first through hole and the second through hole, and the middle part of the cable tie is tightened on one end of the tail pipe 30 facing the accommodation cavity to fix the tail pipe 30 to the partition plate 400.

[0062] In this embodiment, the cable tie can use the partition plate 400 to tighten the water pipe and the tail pipe 30, thereby avoiding water ingress into the gap between the water pipe and the tail pipe 30, and can also play a role in fixing the tail pipe 30. Compared with fixing methods such as adhesion, snap fixing, and magnetic attraction fixing, the fixing effect of the cable tie in this embodiment is stronger, and its stability is higher. At the same time, it can avoid the phenomenon of fixing failure after being washed by water in the adhesion fixing method, and can also avoid the phenomenon of soaring production costs and installation costs caused by using snap fixing and magnetic attraction fixing. In summary, the flusher 10 in this embodiment has a good fixing effect, strong stability, and low production costs.

[0063] Furthermore, please refer to Figures 1 to 5, the rinser 10 further includes a peristaltic pump 700, an overflow valve 300, an encoder 900, a handle support 500, a battery 800, a battery cover 810, and a foot pedal (not shown in the figure); the peristaltic pump 700, the overflow valve 300, and the battery 800 are all located in the first sub-accommodation cavity 110 and are connected to the housing 100. The battery cover 810 covers the battery 800 for fixing and protecting the battery 800. The foot pedal and the encoder 900 are both connected to the circuit board 600, and the circuit board 600 can control the peristaltic pump 700 to provide liquids with different flow rates. The battery 800 is used to supply power to structures such as the peristaltic pump 700, the overflow valve 300, and the circuit board 600. The handle support 500 can be used to place and store the handle 40.

[0064] When it is necessary to control the operation of the rinser 10, the rinser 10 can be started by stepping on the foot pedal, and the encoder 900 can be adjusted to the corresponding gear, thereby realizing the control of the liquid flow rate. Compared with the design of only controlling the operation of the rinser 10 through a touch screen or a button, the combination of the foot pedal and the encoder 900 adopted by the rinser 10 in this embodiment can avoid accidental activation of the rinse and can realize the adjustment of the liquid flow rate in multiple gears by means of the encoder 900, so as to adapt to the needs of different users.

[0065] It should be understood that shock-absorbing elastic members can be arranged around the peristaltic pump 700, and the shock-absorbing elastic members can prevent the peristaltic pump 700 from colliding rigidly with the housing 100 during operation, which may cause damage or leakage at the connection between the peristaltic pump 700 and the water pipe.

[0066] A medical device, please refer to Figures 1 to 3 , the medical device includes the rinser 10 of the above-mentioned utility model embodiment.

[0067] In this embodiment, since the medical device includes the rinser 10 of the above-mentioned utility model, the partition plate 400 divides the accommodation cavity into a first sub-accommodation cavity 110 and a second sub-accommodation cavity 120, thereby avoiding the short circuit of the circuit board 600 and improving the service life of the medical device.

[0068] Furthermore, please refer to Figures 1 to 4 , the medical device further includes a handle 40, a connecting wire, and a water pipe. The handle 40 is used to guide the liquid to flow out of the water pipe. One end of the water pipe is connected to the water path structure, and the other end is connected to the handle 40;

[0069] One end of the connecting wire is connected to the rinser 10, and the other end is connected to the handle 40, and the length of the connecting wire is less than the length of the water pipe.

[0070] In this embodiment, during the use of the handle 40, it may occur that pulling the handle 40 causes the connection between the water pipe and the irrigator 10 or between the water pipe and the handle 40 to be disconnected, thereby resulting in liquid leakage. In this embodiment, a connecting line is passed through the water pipe, with one end connected to the dental cleaner and the other end connected to the handle 40, so that the connecting line can strengthen the overall strength of the medical device and prevent the water pipe from being directly pulled and broken. At the same time, since the length of the connecting line is less than that of the water pipe, during the use of the handle 40, the connecting line will be the main force-bearing object, and the water pipe will only be subjected to the pulling force after the connecting line breaks or extends. It should be understood that the water pipe can be passed through the tail pipe 30 to protect the water pipe from wear by the tail pipe 30. The connecting line can be located inside the water pipe or between the water pipe and the tail pipe 30. At this time, the connecting line is parallel to the water pipe.

[0071] Further, please refer to Figures 1 to 5 , the medical device further includes a fixing member 50. One end of the handle 40 is provided with a fixing groove 41. The fixing member 50 is located in the fixing groove 41 and is connected to the handle 40;

[0072] The side wall of the fixing member 50 is provided with a fixing hole 51, and the connecting line passes through the fixing hole 51 to be fixed in the fixing groove 41.

[0073] If the connecting line is directly connected to the outside of the handle 40, the connecting line may be worn or broken due to bumps during the use of the handle 40.

[0074] In this embodiment, the fixing member 50 is located in the fixing groove 41 and can pass through the through hole for the connecting line to pass through and be tied to the fixing member 50, thereby preventing the connecting line from being exposed to the outside and causing it to break. At the same time, the connecting line is connected to the fixing member 50, rather than internal components such as buttons, nozzles, and syringes, which can prevent the above components from being disengaged from their predetermined positions when the handle 40 is pulled, resulting in partial malfunction of the handle 40.

Specific examples are used in this article to elaborate on the principles and implementation manners of the present application. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present application.
