[0051] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0052] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0053] When the following description refers to the 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 the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0054] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0056] See also Figure 1-Figure 3 The present application proposes a cleaning tool 1, which is an auxiliary tool for cleaning the oral cavity, nasal cavity, ear cavity, etc. It can pressurize the liquid and then spray it out to clean the organs. In the embodiment of the present application, the cleaning tool 1 may include at least one of a tooth irrigator, a nasal washer, and an ear irrigator. The tooth irrigator, the nasal washer, and the ear irrigator are auxiliary tools for cleaning the oral cavity, the nasal cavity, and the ear cavity. The present embodiment does not limit the specific type of the cleaning tool. In order to facilitate the description of the following content, the following embodiment takes the cleaning tool 1 as a tooth irrigator, and introduces in detail the advantage of the cleaning tool 1 of the present application that it is convenient to clean the liquid on the surface of the water tank 31.

[0057] It is understandable that the cleaning tool 1 sprays the dental rinse in the form of a pulsed water column to clean the teeth and the gaps between teeth, wherein the dental rinse may include water or a cleaning liquid. Figure 4 In the embodiment of the present application, the cleaning tool 1 includes a nozzle 10 , a main unit module 20 and a water tank module 30 .

[0058] The nozzle 10 can be arranged in a long strip shape, and the material of the nozzle 10 can be a plastic material such as PP (Polypropylene, polypropylene), so as to have the advantages of light weight, relatively favorable price, and easy processing and manufacturing. In addition, the nozzle 10 made of plastic material can also prevent the user from scratching the skin in the mouth when inserting the nozzle 10 into the mouth, thereby improving the user experience. Of course, the material of the nozzle 10 can also be a metal material, so as to have the advantages of better strength and durability, etc., and this embodiment does not limit this.

[0059] The host module 20 is the main body part of the cleaning tool 1. Specifically, the host module 20 may include a housing 23 and a pump body 21. A housing cavity 23a may be formed in the housing 23, and the housing cavity 23a is used to accommodate the pump body 21. It can be understood that the pump body 21 is connected to the nozzle 10 to pump the extracted liquid to the nozzle 10, and then the liquid is ejected to the teeth and the gaps between the teeth through the nozzle 10. The pump body 21 may be in the form of a plunger pump, a peristaltic pump, or a diaphragm pump, etc., which is not limited in this embodiment.

[0060] The water tank module 30 is the liquid storage part in the cleaning tool 1. Specifically, the water tank module 30 includes a water tank 31. The water tank 31 can be semi-cylindrical and can be made of plastic material to have the advantages of light weight and good corrosion resistance. Of course, the water tank 31 can also be made of metal, which is not limited in this embodiment.

[0061] The water tank 31 is connected to the host module 20. The water tank 31 is used to store the rinsing liquid, and the water tank 31 is connected to the pump body 21. In this way, the user can first inject the rinsing liquid into the water tank 31, and the pump body 21 can pump the liquid in the water tank 31 to the nozzle 10, completing the complete transmission process of the rinsing liquid.

[0062] During actual use, the dental rinse is easy to stick to the surface of the water tank 31. For example, when the dental rinse remains on the inner wall of the water tank 31, if the user does not use the cleaning tool 1 for a long time, the dental rinse remaining on the inner wall of the water tank 31 will easily cause bacteria to grow inside the water tank 31, affecting the health and safety of the user.

[0063] For another example, a gap is usually provided on the outer wall of the water tank 31 to increase the friction coefficient of the outer wall of the water tank 31, so that the user can hold the outer wall of the water tank 31 more firmly when using the cleaning tool 1, to prevent the cleaning tool 1 from falling off the user's hands or unstable operation of the user due to the user's slippery hands or the water tank 31 being too slippery. It can be understood that during the use of the cleaning tool 1, the irrigating liquid flushed out during flushing will partially flow to the outer wall of the water tank 31, and based on the existence of the gap, the irrigating liquid will easily remain in the gap, and the user usually cannot wipe out all the irrigating liquid in the gap, which will cause bacteria to easily grow in the gap.

[0064] Therefore, to resolve this technical issue, please refer to Figure 4-Figure 5 In this embodiment, a hydrophobic layer 312 is provided on the inner wall of the water tank 31 , or a hydrophobic layer 312 is provided on the outer wall of the water tank 31 , or a hydrophobic layer 312 is provided on both the inner wall and the outer wall of the water tank 31 .

[0065] It is understandable that the inner wall of the water tank 31 may be provided with the hydrophobic layer 312 as a whole or partially, and the outer wall of the water tank 31 may be provided with the hydrophobic layer 312 as a whole or partially, and this embodiment does not limit this.

[0066] Among them, the hydrophobic layer 312 can include at least one of a hydrophobic film and a hydrophobic nanostructure. The hydrophobic film can be attached or coated on the wall of the water tank 31, and the hydrophobic nanostructure can be directly formed on the wall of the water tank 31 by processing, such as forming nanoparticles, nanowires or nanotubes on the wall of the water tank 31.

[0067] Thus, in this embodiment, by providing a hydrophobic layer 312 on the inner wall of the water tank 31, the liquid originally in the water tank 31 cannot adhere to the inner wall of the water tank 31, and can flow along the inner wall of the water tank 31 to the bottom of the water tank 31, so that it is easier to be sucked clean by the pump body 21 of the host module 20 when the cleaning tool 1 is used, so that the inner wall of the water tank 31 is not easily stained with dental flushing liquid, and the risk of bacteria breeding inside the water tank 31 when the cleaning tool 1 is not used for a long time is reduced. In addition, in this way, the user does not need to take a paper towel or towel to clean the inner wall of the water tank 31 after use, which improves the convenience of the user to clean the inner wall of the water tank 31.

[0068] Alternatively, in this embodiment, a hydrophobic layer 312 is provided on the outer wall of the water tank 31, so that the liquid originally attached to the outer wall of the water tank 31 cannot adhere to the outer wall or the gaps in the outer wall, thereby reducing the risk of bacteria breeding on the outer wall and the gaps in the water tank 31. In addition, even if some liquid adheres to the outer wall and the gaps in the outer wall, the user only needs to shake the water tank 31 lightly, and the liquid will fall off, which is very convenient to operate and prevents the liquid from wetting the user's hands, clothes or bags.

[0069] Alternatively, the present embodiment provides a hydrophobic layer 312 on the inner and outer walls of the water tank 31, so that the inner wall of the water tank 31 is not easily stained with tooth rinse solution, thereby reducing the risk of bacteria breeding inside the water tank 31, the outer wall of the water tank 31 and the gaps in the outer wall. In addition, after use, the user does not need to take paper towels or towels to clean the inner and outer walls of the water tank 31, thereby improving the convenience of the user in cleaning the liquid on the inner and outer walls of the water tank 31.

[0070] In order to facilitate the user to view the water level in the water tank 31 when using the cleaning tool 1, in some embodiments, refer to Figure 5The water tank 31 and the hydrophobic layer 312 are both made of translucent materials. For example, the water tank 31 can be made of translucent plastic material. The hydrophobic layer 312 includes an inner hydrophobic layer 3121 disposed on the inner wall of the water tank 31 and a first outer hydrophobic layer 3122 disposed on the outer wall of the water tank 31. The inner hydrophobic layer 3121 and the first outer hydrophobic layer 3122 are both made of translucent materials. In this way, in the use scenario where the user injects dental flushing liquid into the water tank 31, or in the use scenario where the user uses the cleaning tool 1 to flush teeth, since the water tank 31 itself has translucent properties and the hydrophobic layer 312 does not block the water tank 31, the user can directly observe the water tank 31 at any time to obtain the current water level information inside the water tank 31, thereby improving the user's use experience.

[0071] Of course, the present application is not limited thereto. In other embodiments, the water tank 31 and the hydrophobic layer 312 may also be made of semi-transparent material or non-transparent material.

[0072] See also Figure 5 In some embodiments, the hydrophobic layer 312 includes a first outer hydrophobic layer 3121 disposed on the outer wall of the water tank 31 and an inner hydrophobic layer 3122 disposed on the inner wall of the water tank 31. In actual use, when the user holds the cleaning tool 1, the user usually touches the outer wall of the water tank 31, and thus the user frequently touches the first outer hydrophobic layer 3121, causing the first outer hydrophobic layer 3121 to fall off easily.

[0073] Based on this, in this embodiment, the thickness of the first outer hydrophobic layer 3121 is set to be greater than the thickness of the inner hydrophobic layer 3122. In this way, while ensuring the good hydrophobic properties of the inner hydrophobic layer 3122 and the first outer hydrophobic layer 3121, by increasing the thickness of the first outer hydrophobic layer 3121, the risk of the first outer hydrophobic layer 3121 falling off due to excessive contact between the user's hands and the first outer hydrophobic layer 3121 can be reduced.

[0074] Please continue reading Figure 5 Furthermore, the thickness of the first outer hydrophobic layer 3121 is greater than or equal to 50 μm and less than or equal to 200 μm. In this way, when the user's hand touches the outer wall of the water tank 31, the risk of the first outer hydrophobic layer 3121 falling off can be reduced, and the production cost of the cleaning tool 1 is increased due to the excessive thickness of the first outer hydrophobic layer 3121.

[0075] If the thickness of the first outer hydrophobic layer 3121 is less than 50 μm, the first outer hydrophobic layer 3121 is easily detached when the user's hand touches the outer wall of the water tank 31; if the thickness of the first outer hydrophobic layer 3121 is greater than 200 μm, the production cost of the cleaning tool 1 will increase. For example, the thickness of the first outer hydrophobic layer 3121 can be 50 μm, 100 μm, 150 μm or 200 μm, etc., and this embodiment does not limit this.

[0076] See also Figure 4 In some embodiments, the water tank 31 is inactively connected to the host module 20. It is understood that the inactive connection form referred to here means that there is no relative movement between the water tank 31 and the host module 20, such as no relative movement, sliding or rotation between the two.

[0077] On the basis of the inactive connection between the water tank 31 and the host module 20, it is possible to prevent the host module 20 from scratching the hydrophobic layer 312 arranged on the outer wall of the water tank 31 or the hydrophobic layer 312 arranged on the inner wall of the water tank 31 when the host module 20 moves relative to the water tank 31, or scraping off the hydrophobic layer 312, thereby causing the hydrophobic layer 312 to fail. Such a configuration can effectively extend the service life of the hydrophobic layer 312.

[0078] Furthermore, the cleaning tool 1 has a height direction, and the water tank 31 is fixedly connected to the host module 20 along the height direction. In this way, through the layout of the water tank 31 and the host module 20, the cleaning tool 1 can reduce its size in a direction perpendicular to the height direction, making the cleaning tool 1 more compact.

[0079] Alternatively, see Figure 4 The cleaning tool 1 has a height direction, and the water tank 31 is fixedly connected to the host module 20 along a direction perpendicular to the height direction. In this way, through the layout of the water tank 31 and the host module 20, the cleaning tool 1 can reduce its size in the height direction, improve the compactness of the cleaning tool 1, and optimize the overall layout.

[0080] See also Figure 4 , Figure 7 as well as Figure 8 In some embodiments, the water tank 31 has a first connection structure 311, the host module 20 has a second connection structure 22, and the first connection structure 311 is fixedly connected to the second connection structure 22. In this way, the water tank 31 and the host module 20 can be relatively fixed by the cooperation of the first connection structure 311 and the second connection structure 22, so that the water tank 31 and the host module 20 are inactively arranged, so as to prevent the host module 20 from scratching the hydrophobic layer 312 or scraping off the hydrophobic layer 312 and causing the hydrophobic layer 312 to fail.

[0081] Exemplarily, the first connecting structure 311 includes a first magnetic part, and the second connecting structure 22 includes a second magnetic part that is magnetically matched with the first magnetic part. The first magnetic part and the second magnetic part have opposite magnetism, or one of the first magnetic part and the second magnetic part is made of metal, and the other is a magnetic part. In this way, through the magnetic matching of the two, while ensuring a good connection firmness, the water tank 31 and the host module 20 can be quickly disassembled and assembled, and there is no need to use additional tools to achieve the connection or disassembly of the two. Of course, the first connecting structure 311 and the second connecting structure 22 can also be other forms such as snap-on or screw-on, which is not limited to this embodiment.

[0082] See also Figure 7 In some embodiments, the water tank 31 is detachably connected to the host module 20, for example, it can be magnetically connected, snap-connected or screwed, etc. The water tank 31 has a first connection surface 313 for connecting to the host module 20. It can be understood that on the basis of the detachable connection between the two, there will be a situation where the water tank 31 is separated from the host module 20, and there will be a gap between the water tank 31 and the host module 20, and the first connection surface 313 is configured to form a partial gap.

[0083] Based on this, the hydrophobic layer 312 includes a first outer hydrophobic layer 3122, and at least a portion of the first outer hydrophobic layer 3122 is disposed on the first connection surface 313. In this way, the liquid originally stained on the first connection surface 313 cannot adhere to the first connection surface 313, thereby reducing the risk of bacteria breeding on the first connection surface 313 and facilitating the user to clean the first connection surface 313.

[0084] Please refer to Figures 7 and 8 , further, the host module 20 also includes a housing 23, the pump body 21 is accommodated in the housing 23, and the housing 23 is detachably connected to the water tank 31;

[0085] The second outer hydrophobic layer 232 is disposed on the entire outer surface of the shell 23 , or the shell 23 has a second connection surface 231 opposite to and connected to the first connection surface 313 , and the second outer hydrophobic layer 232 is disposed on the second connection surface 231 .

[0086] It is understandable that the first connection surface 313 and the second connection surface 231 jointly define the above-mentioned gap. Whether the second outer hydrophobic layer 232 is disposed on the entire outer surface of the housing 23 or on the second connection surface 231, the risk of bacteria breeding in the gap can be reduced. At the same time, it is also convenient to clean the second connection surface 231 or the entire outer surface of the housing 23.

[0087] It should be noted that the second outer hydrophobic layer 232 may be made of the same material as the hydrophobic layer 312 , so the second hydrophobic layer 232 will not be described in detail. Of course, the material of the second outer hydrophobic layer 232 may also be different from that of the hydrophobic layer 312 , and this embodiment does not limit this.

[0088] In some embodiments, the water tank 31 is movably connected to the host module 20, wherein the movably connected may include a sliding connection, a rotating connection, etc.

[0089] On the basis of the sliding connection between the water tank 31 and the host module 20, the host module 20 does not contact the hydrophobic layer 312 when sliding relative to the water tank 31. For example, a receiving cavity may be formed in the water tank 31, and the host module 20 slides relative to the water tank 31 to slide into or out of the receiving cavity. When the host module 20 slides relative to the water tank 31, the host module 20 of this embodiment does not contact the inner hydrophobic layer 3121, so that it can be prevented from scratching the inner hydrophobic layer 3121 or scraping off the inner hydrophobic layer 3121 when the host module 20 slides relative to the water tank 31, causing the inner hydrophobic layer 3121 to fail.

[0090] Exemplarily, the cavity wall of the accommodating cavity of the water tank 31 is provided with an inner hydrophobic layer 3121, and the cavity wall of the accommodating cavity is provided with a slider and a slide groove, and the outer wall surface of the host module 20 is provided with the other of the slider and the slide groove. Through the sliding cooperation of the slider and the slide groove, the water tank 31 and the host module 20 can be slidably connected, and the host module 20 can be prevented from contacting the inner hydrophobic layer 3121 when sliding relative to the water tank 31.

[0091] In some embodiments, the hydrophobic layer 312 includes a first outer hydrophobic layer 3122 disposed on the outer wall of the water tank 31, the water tank 31 is sleeved on the outer side of the host module 20, and the host module 20 is slidably connected to the water tank 31. It can be understood that a receiving cavity may be formed in the water tank 31, and the host module 20 slides relative to the water tank 31 to slide into or out of the receiving cavity. Therefore, in the actual sliding process, the host module 20 will not come into contact with the first outer hydrophobic layer 3122, so that the host module 20 can avoid scratching or scraping off the first outer hydrophobic layer 3122 when sliding relative to the water tank 31.

[0092] See also Figure 4 and Figure 6 In some embodiments, the hydrophobic layer 312 includes an inner hydrophobic layer 3121 , and the inner hydrophobic layer 3121 is disposed on the inner wall of the water tank 31 . The cleaning tool 1 further includes a water-drawing pipe 40 .

[0093] The water drawing pipe 40 is arranged in the water tank 31 and is connected and communicated with the pump body 21, and is used for conveying the tooth flushing liquid in the water tank 31 to the pump body 21. In this way, through the setting of the water drawing pipe 40, the amount of liquid remaining in the water tank 31 is effectively reduced, and it is helpful to reduce the probability of leakage of the liquid in the process of being transmitted from the water tank 31 to the pump body 21. Not only that, the setting of the water drawing pipe 40 can also facilitate the docking operation between the pump body 21 and the water tank module 30, and the docking is faster and more accurate.

[0094] Specifically, the water-drawing pipe 40 is a hose, so that the water-drawing pipe 40 can be deformed when in contact with the inner hydrophobic layer 3121. In this way, even if the water-drawing pipe 40 moves relative to the water tank 31 and comes into contact with the inner hydrophobic layer 3121, the soft nature of the hose can effectively reduce the probability of the water-drawing pipe 40 as a hose scratching the inner hydrophobic layer 3121 or scraping off the hydrophobic layer 3121.

[0095] Alternatively, the water-drawing pipe 40 is spaced from the inner hydrophobic layer 3121. In this way, it is possible to prevent the water-drawing pipe 40 from scratching the inner hydrophobic layer 3121 or scraping off the inner hydrophobic layer 3121, thereby preventing the inner hydrophobic layer 3121 from failing. The water-drawing pipe 40 may be a hose, so that even if the water-drawing pipe 40 contacts the inner hydrophobic layer 3121, it is possible to further prevent the water-drawing pipe 40 from scratching or scraping off the inner hydrophobic layer 3121. Of course, the water-drawing pipe 40 may also be made of other materials, such as a hard pipe, which is not limited here.

[0096] Alternatively, the water-drawing pipe 40 can be deformed when in contact with the inner hydrophobic layer 3121. In this way, based on the relatively soft nature of the water-drawing pipe 40 itself, it can be prevented from scratching the inner hydrophobic layer 3121 or scraping off the inner hydrophobic layer 3121, thereby causing the inner hydrophobic layer 3121 to fail. The water-drawing pipe 40 can be a soft tube, so that even if the water-drawing pipe 40 contacts the inner hydrophobic layer 3121 due to excessive shaking, it can further prevent the water-drawing pipe 40 from scratching or scraping off the inner hydrophobic layer 3121. Of course, the water-drawing pipe 40 can also be made of other materials, such as a hard tube, which is not limited here.

[0097] See also Figure 4 and Figure 6 In some embodiments, the water-drawing pipe 40 is a hard pipe and is fixed in position in the water tank 31 so as to be spaced apart from the inner hydrophobic layer 3121. In this embodiment, although the strength of the water-drawing pipe 40 is relatively hard, by fixing the water-drawing pipe 40 in position in the water tank 31 and spacing it apart from the inner hydrophobic layer 3121, it is possible to effectively prevent the water-drawing pipe 40 as a hard pipe from scratching the inner hydrophobic layer 3121 or scraping off the inner hydrophobic layer 3121, thereby preventing the inner hydrophobic layer 3121 from failing due to the water-drawing pipe 40 being a hard pipe.

[0098] See also Figure 4 and Figure 6 In some embodiments, an inner hydrophobic layer 3121 is provided on the inner bottom wall of the water tank 31 to reduce the risk of the dental rinse adhering to the inner bottom wall of the water tank 31 through the provision of the inner hydrophobic layer 3121 .

[0099] The cleaning tool 1 has a height direction, and along the height direction, there is a first distance between the water inlet end 41 of the water drawing pipe 40 and the inner bottom wall of the water tank 31, and the first distance is not less than 0.5 mm and not more than 4 mm. When the first distance is not less than 0.5 mm and not more than 4 mm, it can ensure that there is a certain safety distance between the water inlet end 41 of the water drawing pipe 40 and the inner bottom wall of the water tank 31, reducing the risk of contact between the two, and ensuring that when the water pump is driven, the toothwash solution adhered to the inner bottom wall of the water tank 31 can also enter the water inlet end 41 of the water drawing pipe 40.

[0100] If the first distance is less than 0.5 mm, there is a greater risk of contact between the water inlet end 41 of the water pumping tube 40 and the inner bottom wall of the water tank 31, which may easily cause the water inlet end 41 of the water pumping tube 40 to scratch or scrape off the inner hydrophobic layer 3121 arranged on the inner bottom wall of the water tank 31; if the first distance is greater than 4 mm, when the water pump is driven, the dental flushing liquid stuck to the inner bottom wall of the water tank 31 cannot enter the water inlet end 41 of the water pumping tube 40 well, affecting the extraction effect of the pump body 21.

[0101] Illustratively, the first distance may be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm or 4 mm, etc., which is not limited in this embodiment.

[0102] See also Figure 4 and Figure 6 In some embodiments, the inner bottom wall of the water tank 31 is not provided with an inner hydrophobic layer 3121, and the water tank module 30 also includes a gravity ball (not shown in the figure), which is connected and communicated with the water inlet end 41 of the water pumping pipe 40, and the gravity ball can contact the inner bottom wall of the water tank 31.

[0103] In this way, on the basis of providing a gravity ball, the gravity of the gravity ball makes the water drawing pipe 40 always close to the bottom of the water tank 31, so that under the drive of the pump body 21, the tooth flushing liquid can better enter the water drawing pipe 40 to ensure the extraction efficiency. Based on the contact between the gravity ball and the inner wall surface of the water tank 31, the inner bottom wall of the water tank 31 is correspondingly not provided with an inner hydrophobic layer 3121 to avoid the gravity ball from scratching or scraping off the inner hydrophobic layer 3121 originally provided on the inner bottom wall of the water tank 31.

[0104] See also Figure 4 and Figure 6In some embodiments, the inner bottom wall of the water tank 31 has a groove 31c that is recessed toward the outside of the water tank 31, and the water inlet end 41 of the water-drawing pipe 40 is disposed opposite to the groove 31c.

[0105] It can be understood that based on the setting of the groove 31c, the overall volume inside the water tank 31 can be increased first, and the dental flushing solution will flow into the groove 31c due to its own weight to be gathered in the groove 31c. On the basis that the water inlet end 41 of the water drawing pipe 40 is opposite to the groove 31c, when the pump body 21 is working, the dental flushing solution gathered in the groove 31c can better flow to the water inlet end 41 of the water drawing pipe 40, thereby greatly improving the extraction efficiency.

[0106] See also Figure 7-Figure 8 In some embodiments, the hydrophobic layer 312 includes an inner hydrophobic layer 3121, and the inner hydrophobic layer 3121 is disposed on the inner wall of the water tank 31. The water tank 31 has a water inlet 31a, that is, the user can inject dental flushing solution into the water tank 31 through the water inlet 31a, so that the water tank 31 can store the dental flushing solution.

[0107] The water tank module 30 also includes a cover 32, which is movably connected to the water tank 31 to open or close the water inlet 31a, that is, when it is necessary to inject dental rinse solution into the water tank 31, the cover 32 can be manipulated to open the water inlet 31a, and after the injection is completed, the cover 32 can be manipulated to close the water inlet 31a, which is easy to operate and can reduce the risk of dental rinse solution overflowing when the water inlet 31a is closed. Exemplarily, the movable connection between the cover 32 and the water tank 31 can be a sliding connection, a plug connection, or a hinge connection.

[0108] The cover body 32 may be configured not to extend into the water tank 31 , so as to prevent the cover body 32 from scratching the inner hydrophobic layer 3121 or scraping off the inner hydrophobic layer 3121 and causing the inner hydrophobic layer 3121 to fail.

[0109] Alternatively, the portion of the cover body 32 extending into the water tank 31 is soft rubber. In this way, even if the portion of the cover body 32 extending into the water tank 31 comes into contact with the inner hydrophobic layer 3121, due to the soft properties of the soft rubber itself, the portion of the cover body 32 extending into the water tank 31 has a smaller chance of scratching the inner hydrophobic layer 3121 or scraping off the hydrophobic layer 3121, thereby better protecting the inner hydrophobic layer 3121.

[0110] See also Figure 7-Figure 9 Furthermore, the water tank 31 also has a mounting hole 31b disposed adjacent to the water inlet 31a. The cover body 32 includes a hard outer cover 321 and a soft rubber inner lining 322 .

[0111] The hard shell can be made of plastic or metal with high hardness, so that the hard shell has a certain strength and is easy for users to operate. The soft rubber lining 322 includes a main body 3221 and an insertion part 3222 connected to each other. The main body 3221 is arranged on the inner wall of the hard outer cover 321 and is used to open or close the water inlet 31a. The insertion part 3222 can be movably arranged in the installation hole 31b and inserted into the water tank 31.

[0112] It is understandable that when closing the water inlet 31a, the user can first align the position of the insertion portion 3222 with the mounting hole 31b, and then make the insertion portion 3222 penetrate the mounting hole 31b to extend into the water tank 31, which plays a role of pre-positioning to a certain extent, and the connection between the insertion portion 3222 and the mounting hole 31b is firm, ensuring the firmness of the cover body 32 closing the water inlet 31a, and the insertion portion 3222 will also block the water inlet 31a. When opening the water inlet 31a, the user can operate the hard shell and pull out the hard shell, at which time the main body 3221 will be separated from the water tank 31, and the insertion portion 3222 will also be separated from the mounting hole 31b, for example, elastic deformation occurs to separate from the mounting hole 31b, and the operation is very convenient.

[0113] In this way, based on the setting of the soft rubber lining 322, when the extending portion 3222 extends into the water tank 31 or extends out of the water tank 31, even if it contacts the inner hydrophobic layer 3121, due to the soft characteristics of the soft rubber itself, the extending portion 3222 has a smaller chance of scratching the inner hydrophobic layer 3121 or scraping off the hydrophobic layer 3121, thereby better protecting the inner hydrophobic layer 3121.
