DETAILED DESCRIPTION

[0034] In order to enable personnel in the technical field to better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor should fall within the scope of protection of the present application.

[0035] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0036] Regarding the electrolysis technology mentioned in the background art, the applicant further explains as follows:

[0037] When water is electrolyzed, in the reaction occurring at the anode, water molecules lose hydrogen atoms therein, and the remaining oxygen atoms combine to form hydroxyl radicals, ozone and oxygen. Hydroxyl radicals and ozone both have strong oxidizing ability, and thus have strong disinfection and sterilization effects. The present scheme is to utilize the substances with disinfection and sterilization effects generated in the process of electrolyzing water to clean and sterilize the user's oral cavity.

[0038] Taking a mouth cup as an example, in the prior art, if the amount of water in the mouth cup is large, the time for fully electrolyzing the water increases, and the waiting time of the user also increases. If the amount of water in the mouth cup is small, considering that the environment in the mouth cup is relatively humid, bacteria are more likely to breed. Therefore, even if the concentration of the electrolysis product in the mouth cup reaches the required standard, the electrolysis product may be contaminated by the bacteria breeding on the cup wall or consumed by the bacteria breeding on the cup wall in the process of entering the user's oral cavity from the bottom of the cup along the cup wall, so that the oral cavity cannot be fully sterilized and cleaned.

[0039] In view of this, as shown in the present application, a mouth cleaning device is provided, which comprises: Figures 1-3

[0040] The liquid outlet end, i.e. the drinking end of the user;

[0041] ​The first accommodating cavity 1 and the second accommodating cavity 2 are arranged in series, the first accommodating cavity 1 is arranged between the liquid outlet end and the second accommodating cavity 2, and the second accommodating cavity 2 is used for storing the raw liquid participating in electrolysis of the electrolysis unit 3;

[0042] The electrolysis unit 3 is arranged on the liquid outlet path of the raw liquid and on one side of the first accommodating cavity 1.

[0043] The check valve unit 4 is arranged in the first accommodating cavity 1 and is used for retaining at least part of the liquid entering the first accommodating cavity 1.

[0044] In the present application, the liquid in the second accommodating cavity 2 enters the first accommodating cavity 1 under the action of an external force, by adding the first accommodating cavity 1 between the second accommodating cavity 2 and the liquid outlet end, the amount of electrolytic product required for cleaning the oral cavity is limited by the first accommodating cavity 1, which shortens the waiting time of the user, and at the same time, since the electrolysis unit 3 is arranged on the liquid outlet path on one side of the first accommodating cavity 1, the distance between the electrolytic product and the liquid outlet end is shortened, thereby reducing the unnecessary consumption of the electrolytic product, and thereby fully guaranteeing the cleaning and sterilization effect on the oral cavity of the user.

[0045] The volume of the first accommodating cavity 1 can be determined according to the amount of electrolytic product required for one-time oral cleaning of the user, and the volume of the first accommodating cavity 1 is preferably smaller than the volume of the second accommodating cavity 2, at which time the second accommodating cavity 2 can supply liquid to the first accommodating cavity 1 multiple times, reducing the liquid adding frequency of the user to the second accommodating cavity 2, thereby further ensuring the user experience.

[0046] The electrolysis unit 3 can be directly arranged in the first accommodating cavity 1 to electrolyze the raw liquid entering the first accommodating cavity 1, or considering that in a specific use scenario, the user needs to drink the electrolytic product in the first accommodating cavity 1, a cover 5 can be arranged outside the first accommodating cavity 1 to avoid external dust from polluting the first accommodating cavity 1, and the connection form of the two can be arranged as a detachable connection form such as threaded connection.

[0047] When the cover 5 is arranged, the electrolysis unit 3 can be connected to one end of the cover 5 and extended in the direction close to the first accommodating cavity 1, for example, when the oral cleaning device is upright, the electrolysis unit 3 can be suspended in the accommodating space 12, or one side can be arranged in close contact with the inner wall of the accommodating space 12, in order to ensure the electrolysis efficiency of the electrolysis unit 3, the electrolysis unit 3 is preferably suspended in the accommodating space 12, so that the electrode sheets on both sides of the electrolysis unit 3 can directly contact the raw liquid.

[0048] When the electrolysis unit 3 is connected to the cover 5, the power supply assembly thereof can be hidden in the cover 5 to ensure the appearance of the oral cleaning device, and the power supply assembly can be directly connected to an external power source or can be arranged in the form of a battery for storing electricity.

[0049] In another aspect, the first accommodating cavity 1 can be supplemented with liquid by the second accommodating cavity 2. The second accommodating cavity 2 can be disposable or, when it is necessary to supplement the second accommodating cavity 2 with liquid, the first accommodating cavity 1 needs to be detached from the second accommodating cavity 2, that is, the first accommodating cavity 1 and the second accommodating cavity 2 need to be detachably connected.

[0050] Specifically, the first accommodating cavity 1 in the application can be detachably arranged at the end of the open end of the second accommodating cavity 2. The two can be connected by threads or, for the convenience of users to detach, the first accommodating cavity 1 can be directly hung at the end of the open end of the second accommodating cavity 2. At this time, in order to avoid the first accommodating cavity 1 from falling off when the oral cleaning device is inverted, when the cover 5 is buckled on the outside of the first accommodating cavity 1, the side of the cover 5 facing the first accommodating cavity 1 is limited to the end of the open end of the second accommodating cavity 2. The first accommodating cavity 1.

[0051] Considering that the first accommodating cavity 1 is suspended at the end of the open end of the second accommodating cavity 2, in order to avoid the first accommodating cavity 1 from falling off when the user drinks the electrolytic product in the first accommodating cavity 1, an elastic support (not shown in the figure) can be arranged on the peripheral wall of the first accommodating cavity 1. When the first accommodating cavity 1 is suspended at the open end of the second accommodating cavity 2, the elastic support is compressed in the direction close to the first accommodating cavity 1 under the action of the open end of the second accommodating cavity 2. Then, under the trend of the elastic support returning to the initial state, the end of the open end of the second accommodating cavity 2 and the first accommodating cavity 1 realize interference fit, so as to realize the stable arrangement of the first accommodating cavity 1 at the end of the open end of the second accommodating cavity 2, avoiding its falling off when the user drinks.

[0052] In an embodiment of the application, the check unit 4 is a sheet structure hinged to the peripheral wall of the liquid inlet 11, and the first accommodating cavity 1 is communicated with the second accommodating cavity 2 through the liquid inlet 11. With the impact of the liquid in the second accommodating cavity 2, the check unit 4 can rotate into the first accommodating cavity 1 from the plane where the liquid inlet 11 is located, and the liquid in the second accommodating cavity 2 can enter the first accommodating cavity 1.

[0053] Specifically, in this embodiment, when the oral cleaning device is in an inverted state, the first accommodating cavity 1 is below the second accommodating cavity 2. At this time, the liquid in the second accommodating cavity 2 opens the check unit 4 at the liquid inlet 11 of the first accommodating cavity 1 under the action of gravity and enters the first accommodating cavity 1. Therefore, in this embodiment, the user can realize the liquid supplement of the first accommodating cavity 1 by inverting the oral cleaning device, which is convenient for the user to operate.

[0054] When the oral cavity cleaning device is in the upright state in the embodiment, the first accommodating cavity 1 is above the second accommodating cavity 2, and the liquid therein cannot flow back to the second accommodating cavity 2 under the action of the check unit 4, so the user can directly use the electrolysis product in the first accommodating cavity 1 to clean the oral cavity. However, in the embodiment, when the user drinks the electrolysis product in the first accommodating cavity 1, the original liquid in the second accommodating cavity 2 may leak out.

[0055] Therefore, in another embodiment of the utility model, the check unit 4 is protrudingly arranged on the inner wall where the liquid inlet 11 of the first accommodating cavity 1 is located, and at least one passage 41 is arranged in the check unit 4 to communicate the liquid inlet 11 and the interior of the first accommodating cavity 1.

[0056] In the embodiment, the user can realize liquid supplement of the first accommodating cavity 1 by squeezing the second accommodating cavity 2, and as the volume of the second accommodating cavity 2 decreases, the original liquid therein flows into the first accommodating cavity 1, or when the user inverts the oral cavity cleaning device, the original liquid in the second accommodating cavity 2 flows into the first accommodating cavity 1 under the action of gravity, and when the user places the oral cavity cleaning device in the upright state, part of the liquid flowing into the first accommodating cavity 1 is retained in the first accommodating cavity 1 under the blockage of the check unit 4, and at this time, the amount of retained liquid is related to the height of the check unit 4, and the higher the height of the check unit 4, the more the amount of retained liquid increases.

[0057] As shown in Figure 1 The second accommodating cavity 2 can be provided with a liquid delivery pipeline 21, one end of the liquid delivery pipeline 21 communicates with the liquid inlet 11 of the first accommodating cavity 1, and the other end extends away from the liquid inlet 11 of the first accommodating cavity 1, and is preferably extended to the inner wall on the opposite side of the liquid inlet 11, so as to deliver the original liquid in the second accommodating cavity 2 to the first accommodating cavity 1 as much as possible.

[0058] When the liquid delivery pipeline 21 is provided, as the user squeezes the second accommodating cavity 2, the volume of the second accommodating cavity 2 decreases, and the original liquid in the second accommodating cavity 2 is delivered to the first accommodating cavity 1 along the liquid delivery pipeline 21, and then retained in the first accommodating cavity 1 under the action of the check unit 4.

[0059] In the embodiment, in order to avoid that when the user squeezes the second accommodating cavity 2, the liquid delivered along the liquid delivery pipeline 21 directly flies out, reducing the user's experience, the liquid outlet 42 of the passage 41 communicating the liquid inlet 11 and the accommodating space 12 of the first accommodating cavity 1 is preferably arranged on the peripheral wall of the check unit 4, and when the liquid delivery pipeline 21 delivers the original liquid, the flow direction of the original liquid changes under the action of the blind end of the check unit 4, so as to avoid that the original liquid directly flies out.

[0060] Alternatively, in order to reduce the user's operating steps, the first accommodating chamber 1 can be replenished with liquid by means of an inverted oral cleaning device. Specifically, in another embodiment of the present application, a sealing member 22 is provided at the liquid inlet 11 of the first accommodating chamber 1, and the cross-sectional area of ​​the sealing member 22 is greater than or equal to the cross-sectional area of ​​the liquid inlet 11, so as to achieve the blocking of the liquid inlet 11.

[0061] As the blocking member 22 moves into the first accommodating chamber 1 or the second accommodating chamber 2 , the liquid inlet 11 of the first accommodating chamber 1 switches to a blocking state or a conducting state.

[0062] The blocking member 22 can be hinged to the peripheral wall of the liquid inlet 11 of the first accommodating chamber 1. Specifically, the blocking member 22 can be rotated from the plane where the liquid inlet 11 is located toward the side of the first accommodating chamber 1. When the user inverts the oral cleaning device, the first accommodating chamber 11 can be replenished with liquid under the action of gravity. However, when the user uses the electrolysis product to clean the oral cavity, the original liquid in the second accommodating chamber 2 may be poured out.

[0063] Therefore, if Figure 2 As shown, in this embodiment, the blocking member 22 is driven to move by a pushing member 51 , and the pushing member 51 can be disposed in the cover body 5 .

[0064] The cover body 5 can be threadedly connected to the first accommodating chamber 1. As the cover body 5 continuously rotates and wraps the first accommodating chamber 1, the pushing member 51 continuously moves into the first accommodating chamber 1, driving the blocking member 22 to move into the second accommodating chamber 2. As the blocking member 22 moves toward the second accommodating chamber 2, the liquid inlet 11 of the first accommodating chamber 1 is in a conductive state. At this time, the oral cleaning device is inverted, and under the action of gravity, the liquid in the second accommodating chamber 2 will flow into the first accommodating chamber 1, thereby realizing automatic liquid replenishment of the first accommodating chamber 1.

[0065] When the user places the oral cleaning device upright, the cover 5 needs to be removed from the first accommodating chamber 1 before the electrolysis product can be used to clean the oral cavity. If the liquid inlet 11 is in a conductive state at this time, the original liquid in the second accommodating chamber 2 will also flow out, reducing the user's experience.

[0066] Therefore, in order to avoid the above situation, Figure 3 As shown, the sealing member 22 is preferably provided with an elastic return member 23. One end of the elastic return member 23 is connected to the sealing member 22, and the other end is connected to a lap member 43 extending inwardly from the inner wall of the check unit 4 or a lap member 43 extending inwardly from the peripheral wall of the liquid inlet 11. As the cover 5 gradually separates from the first accommodating chamber 1, the elastic return member 23 acts to gradually return the sealing member 22 to its original position, blocking the liquid inlet 11 of the first accommodating chamber 1, thereby preventing the liquid in the second accommodating chamber 2 from flowing out when the user consumes the electrolysis product.

[0067] In order to increase the electrolysis efficiency of the electrolysis unit 3, in the embodiment, when the blocking member 22 is arranged at the liquid inlet 11, the liquid outlet 42 of the passage 41 is arranged at the end of the check valve unit 4 opposite to the liquid inlet 11. At this time, when the raw liquid in the second containing cavity 2 enters the first containing cavity 1 through the passage 41 under the action of gravity, there is no loss of flow rate, and the liquid supplementing efficiency is better.

[0068] Preferably, the electrolysis unit 3 is arranged outside the liquid outlet 42 of the passage 41, and the anode sheet and the cathode sheet of the electrolysis unit 3 are arranged in parallel with the plane where the liquid outlet 42 of the passage 41 is arranged, so as to increase the contact area of the anode sheet, the cathode sheet and the raw liquid as much as possible, and improve the electrolysis efficiency.

[0069] The above only describes the preferred embodiments of the present application. It should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
