Description

Technical Field

[0001] Embodiments of the present disclosure relate to, but are not limited to, kitchen and bathroom technologies, and in particular to a liquid storage mechanism, a foaming device, and a kitchen and bathroom system. Background Art

[0002] The magic foam function is generally a standard feature of intelligent kitchen and bathroom systems (such as intelligent toilets, intelligent toilet lids, soap dispensers, and soap sinks). The fast, convenient, and stable foaming performance has attracted increasing attention from consumers and manufacturers. Short foaming time, rich foam, and stable foam liquid are the common pursuits.

[0003] In traditional kitchen and bathroom systems, the foam liquid is generally sucked from the foam liquid storage unit and finally reaches the foaming mechanism for foaming. Generally, foam is generated after a certain amount of the fluid used for mixing with the foam liquid has been discharged. This causes the foaming mechanism to be unable to generate foam immediately, resulting in no foam at the beginning stage of the foam-containing water output of the intelligent kitchen and bathroom system. There is still room for improvement in terms of resource savings and power consumption. Summary of the Invention

[0068] Embodiments of the present disclosure provide a kitchen and bathroom system, which can be installed in various environmental scenarios such as companies, schools, families, factories, etc., to improve and enhance people's living quality and health. The kitchen and bathroom system can be, but is not limited to, an intelligent toilet, an intelligent toilet seat cover, a soap dispenser faucet, or a soap dispenser sink, etc.

[0069] As Figure 1 shown, the intelligent toilet includes a toilet body and a foaming device. The foaming device is disposed inside the electronic cover 10 of the toilet body, and is capable of forming foam from the foam liquid and covering the toilet surface of the toilet body, enabling the intelligent toilet to have excellent self-cleaning efficiency. The intelligent toilet seat cover can replace the cover of an ordinary toilet, making the ordinary toilet have intelligent functions. The intelligent toilet seat cover includes an intelligent toilet seat cover main body and a foaming device. The foaming device is disposed on the intelligent toilet seat cover main body, and is capable of forming foam from the foam liquid and covering the toilet surface of the toilet body, enabling the toilet to have excellent self-cleaning efficiency. The soap dispenser faucet includes a faucet body and a foaming device. The foaming device is disposed on the faucet body, and is capable of forming foam from the foam liquid for cleaning. The soap dispenser sink includes a sink body and a foaming device. The foaming device is disposed on the sink body, and is capable of forming foam from the foam liquid for cleaning.

[0070] As Figure 2As shown in the figure, an embodiment of the present disclosure provides a kitchen and bathroom system. The foaming device includes a liquid storage mechanism 20, a foam liquid storage unit 30, a negative pressure mechanism 40, and a foaming mechanism 50. The foam liquid storage unit 30 has a foam liquid storage space for storing foam liquid.

[0071] Please also refer to Figures 1 to 3 and Figures 5 to 8 , the liquid storage mechanism 20 is provided with a liquid inlet hole 100, a liquid storage cavity 200, a drainage channel 300, and a liquid outlet hole 500. The liquid inlet hole 100 is arranged to communicate the liquid storage cavity 200 with the foam liquid storage space. The volume of the liquid storage cavity 200 is smaller than the volume of the foam liquid storage space. The drainage channel 300 is communicated with the liquid storage cavity 200, and the length of the drainage channel is smaller than the length of the extraction channel for extracting the foaming liquid from the foam liquid storage space. The liquid outlet hole 500 is arranged to communicate the drainage channel 300 with the foaming mechanism 50. The foaming mechanism 50 is arranged to mix the foaming liquid with another fluid to form foam. The other fluid includes but is not limited to water or air, etc.

[0072] The liquid storage mechanism 20 and the foam liquid storage unit 30 are separately arranged or integrally formed.

[0073] The negative pressure mechanism 40 is communicated with the liquid outlet hole 500, and can generate negative pressure at the liquid outlet hole 500 to suck the foam liquid from the liquid inlet hole 100 into the liquid storage mechanism 20 and form foam through the foaming mechanism 50 and discharge it.

[0074] The foam liquid can be an aqueous solution containing a cleaning component and can be stored in the foam liquid storage space. The negative pressure mechanism 40 can be a liquid pump with a power source, including but not limited to liquid pumps such as diaphragm pumps, plunger pumps, centrifugal pumps, and peristaltic pumps that require external force to drive. The negative pressure mechanism 40 can be a Venturi structure that can generate negative pressure when water flows through the water outlet channel of the kitchen and bathroom system. The foaming mechanism 50 can have a mesh structure. The mesh structure can break up the foaming liquid to form foam and discharge it. The foaming mechanism 50 can also introduce other fluids to mix with the foaming liquid to form foam and discharge it. The foaming mechanism 50 can be integrally formed or separately formed with the outer shell of the kitchen and bathroom system. The foaming mechanism 50 can be installed inside or outside the outer shell of the kitchen and bathroom system. The foaming mechanism 50 has a nozzle structure and can discharge the foam in a certain direction.

[0075] When the liquid storage mechanism 20 of the above solution is applied to a foaming device and a kitchen and bathroom system, in addition to enabling the foaming device and the kitchen and bathroom system to have a foaming effect, it can also reduce the travel distance and time of the foam liquid flow, and avoid the situation that there is no foam at the beginning stage of the foam-containing water outlet. When foaming starts, the gas inhaled by the foaming mechanism in the early stage is gas, which affects the foaming effect. Specifically, the liquid storage mechanism 20 is provided with a liquid inlet hole 100, a liquid storage cavity 200, a drainage channel 300, and a liquid outlet hole 500. Among them, the drainage channel 300 is communicated with the liquid storage cavity 200, and is sequentially communicated with the foam liquid storage space through the liquid storage cavity 200 and the liquid inlet hole 100. The drainage channel 300 is also communicated with the foaming mechanism 50 through the liquid outlet hole 500 and the negative pressure mechanism 40. The length of the drainage channel 300 is less than the length of the extraction channel for extracting the foaming liquid from the foam liquid storage space. When foaming, the negative pressure mechanism 40 can inhale the foam liquid in the liquid storage cavity 200 in the first time, so as to avoid directly inhaling the foam liquid from the foam liquid storage space of the foam liquid storage unit 30, resulting in a longer travel distance between the foam liquid and the foaming mechanism 50. Thus, the foam liquid is closer to the foaming mechanism 50, reducing the travel distance and time of the foam liquid flow, enabling the foaming mechanism 50 to immediately generate foam, avoiding the situation of no foam at the beginning stage of the foam-containing water outlet, saving water, reducing the actual working duration of the foam-containing water outlet, and consuming less power. And, under the action of negative pressure, the foam liquid will also continuously supplement into the liquid storage cavity 200 from the foam liquid storage space, ensuring the continuous supply of the foaming liquid, and further ensuring the foaming effect.

[0076] In an exemplary embodiment, please also combine Figure 3 and Figures 5 to 8 , the drainage channel 300 includes a first end 301 and a second end 302. The first end 301 is disposed in the liquid storage cavity 200 and communicated with the liquid storage cavity 200. The liquid outlet hole 500 is arranged to communicate the second end 302 with the foaming mechanism 50. The height of the second end 302, the liquid inlet hole 100 or the first end 301 is not lower than the highest liquid storage height of the foam liquid storage space, so as to avoid the automatic discharge of the foam liquid from the drainage channel 300.

[0077] In an exemplary embodiment, such as Figure 6As shown, the second end 302 is higher than the first end 301 in the direction of gravity, and the connection position 101 between the liquid inlet hole 100 and the liquid storage cavity 200 is located between the first end 301 and the second end 302 in the direction of gravity. In this way, after the foaming stops and the foam liquid in the liquid storage cavity 200 flows back to the foam liquid storage unit 30, the first end 301 can always be placed below the liquid level of the foam liquid in the liquid storage cavity 200. When foaming is carried out again, the negative pressure mechanism 40 connected through the liquid outlet hole 500 at the second end 302 can suck in the mixed liquid on the side of the second end 302 away from the first end 301 in the first instance. Under the action of negative pressure, the foam liquid in the liquid storage cavity 200 will continuously supplement to the second end 302, and the foam liquid will also continuously supplement into the liquid storage cavity 200 from the foam liquid storage unit 30, ensuring that the mixed liquid is continuously supplied to the negative pressure mechanism 40, and thus ensuring the foaming effect.

[0078] In some embodiments, the horizontal plane where the second end 302 is located can also be below the horizontal plane where the connection position 101 is located and / or the horizontal plane where the first end 301 is located in the vertical direction, as long as no negative pressure is generated at the first end 301 to ensure that the foaming liquid does not flow back. For example, the drainage channel can be formed by bending downward to form the highest point of the drainage channel in the vertical direction. After the foaming stops, the foaming liquid can be cut off at the highest point to avoid the foaming liquid from flowing back. In addition, pressure can also be provided at the second end 302 to avoid the foaming liquid from flowing back.

[0079] In some embodiments, the connection position 101 can also be located at other positions. For example, the horizontal plane where the connection position 101 is located can be coplanar with the horizontal plane where the first end 301 is located, or the horizontal plane where the connection position 101 is located is below the horizontal plane where the first end 301 is located in the vertical direction. At this time, a pipeline can be provided between the liquid inlet hole 100 and the connection position 101. The pipeline has a communication channel connecting the liquid inlet hole 100 and the connection position 101. By setting the inclination angle, bending and extending shape, etc. of the pipeline, the plane where the highest point of the communication channel is located can be adjusted to be above the horizontal plane where the first end 301 is located in the vertical direction, and it can also ensure that the first end 301 can always be placed below the liquid level of the foam liquid in the liquid storage cavity 200.

[0080] In an exemplary embodiment, please also refer to Figure 3 and Figures 5 to 8 , the liquid storage mechanism 20 is further provided with an inflow hole 400. The inflow hole 400 and the liquid outlet hole 500 communicate with the second end 302 at the second end 302. The inflow hole 400 is arranged to introduce fluid into the second end 302 to mix with the foaming liquid

[0081] The negative pressure mechanism 40 is communicated with the liquid outlet hole 500, and can form a negative pressure at the liquid outlet hole 500 to suck the foam liquid and the fluid into the liquid storage mechanism 20 from the liquid inlet hole 100 and the liquid inlet hole 400 respectively, form a mixed liquid, and discharge the mixed liquid into the foaming mechanism 50. The foaming mechanism 50 can form and discharge the mixed liquid into foam. Among them, the fluid can be air or water.

[0082] The liquid inlet hole 400 and the liquid outlet hole 500 are communicated with the second end 302 at the second end 302. In this way, after the foaming stops, the fluid can enter the second end 302 through the liquid inlet hole 400, breaking the siphon effect and preventing the mixed liquid on the side of the second end 302 far from the first end 301 from flowing back due to the siphon effect.

[0083] In addition, the foam liquid and the fluid are mixed in the liquid storage mechanism 20, and the foam liquid is also caused to form a mixed liquid with numerous tiny bubbles under the action of the fluid. Compared with the viscous foam liquid, the mixed liquid has a larger volume, is more delicate, has better fluidity, and can quickly form uniform and delicate foam with other liquids in the foaming mechanism 50, so that less foam liquid can achieve a better foaming effect. Compared with the case where the foaming effect is poor when directly foaming in the foaming mechanism 50, by adding the liquid storage mechanism 20, the foam liquid is pre-foamed before being mixed with other liquids, thereby improving the foaming effect. Other liquids include but are not limited to fresh water or pure water from the municipal water network.

[0084] In an exemplary embodiment, please also refer to Figure 5 and Figure 7 , the drainage channel 300 has a main body section 303 and a narrow section 304. The flow-through area of the main body section 303 is larger than that of the narrow section 304. In this way, the setting of the narrow section 304 can pressurize and accelerate the foam liquid passing through the narrow section 304, increase the kinetic energy of the foam liquid, and further improve the uniformity of mixing with the fluid.

[0085] In the embodiment of the present disclosure, the main body section 303 is communicated with the first end 301. The narrow section 304 is communicated between the second end 302 and the main body section 303. It can be understood that in other embodiments, the narrow section 304 can also be communicated with the first end 301 and the second end 302 respectively through the main body section 303.

[0086] In the embodiment of the present disclosure, the first end 301, the main body section 303, the narrow section 304 and the second end 302 are coaxially arranged, and the cross-sectional shapes can all be triangular, rectangular, circular or elliptical, etc.

[0087] In an exemplary embodiment, please continue to refer to Figure 5 and Figure 7 , the drainage channel 300 further has a narrowing section 305, and the narrowing section 305 is located between the second end 302 and the narrow section 304.

[0088] The narrowing section 305 gradually narrows from the second end 302 towards the narrow section 304. In this way, through the setting of the narrowing section 305, when the foam liquid passes through the narrowing section 305 from the narrow section 304, it can release pressure rapidly and diffuse, and spray towards the second end 302 to be mixed with the fluid, further improving the uniformity of mixing with the fluid.

[0089] The second end 302, the narrowing section 305, and the narrow section 304 are coaxially arranged in the vertical direction. In this way, the foam liquid can be sprayed more uniformly towards the second end 302 to be mixed with the fluid. Moreover, it can also increase the difficulty for the foam liquid to enter the narrow section 304 from the narrowing section 305 under the action of gravity, avoiding the backflow of the foam liquid under the action of gravity. In the embodiment of the present disclosure, the narrowing section 305 is in the shape of a frustum of a cone.

[0090] In an exemplary embodiment, please continue to refer to Figure 5 and Figure 7 The drainage channel 300 further has a guiding section 306. The guiding section 306 is located between the first end 301 and the narrow section 304, and the guiding section 306 gradually narrows towards the narrow section 304. In this way, through the setting of the guiding section 306, the foam liquid can enter the narrow section 304 more smoothly. Before entering the narrow section 304, the foam liquid can be gradually compressed and accelerated to form a negative pressure, which is beneficial to driving the foam liquid in the body section 303 to supplement into the narrow section 304. In the embodiment of the present disclosure, the liquid storage mechanism 20 has an annular arc surface located between the narrow section 304 and the body section 303. The annular arc surface encloses to form the guiding section 306 and protrudes towards the inner side of the guiding section 306. The second end 302, the narrowing section 305, the narrow section 304, and the guiding section 306 are coaxially arranged in the vertical direction.

[0091] In an exemplary embodiment, please also refer to Figures 6 to 8 The liquid storage mechanism 20 further has a first flow distribution channel 600. The first flow distribution channel 600 has an inflow end 601 and an outflow end 602. The inflow end 601 is communicated with the inflow hole 400, and the outflow end 602 is arranged around the second end 302 and is communicated with the second end 302. In this way, through the setting of the first flow distribution channel 600, the fluid can enter the second end 302 more uniformly to be mixed with the foam liquid, and the fluid can be discharged from the outflow end 602 surrounding the second end 302 to cut the foam liquid discharged from the second end 302, ensuring that the foam liquid and the fluid in the mixed liquid are mixed more uniformly to form a mixed liquid with numerous microbubbles.

[0092] In an exemplary embodiment, please continue to refer to Figures 6 to 8 The first flow distribution channel 600 is in a conical structure coaxially arranged with the second end 302. The inflow end 601 is located on the large end side of the first flow distribution channel 600. In this way, the fluid can flow more uniformly from the inflow end 601 towards the outflow end 602. The outflow end 602 is located on the small end side of the first flow distribution channel 600.

[0093] The horizontal plane where the outflow end 602 is located and the plane where the inflow end 601 is located are arranged vertically one above the other. In this way, the direction in which the first flow channel 600 controls the movement of the fluid is inclined relative to the vertical direction, enabling the fluid to easily overcome the gravity of the mixed liquid remaining in the first flow channel 600 and driving the above-mentioned mixed liquid into the second end 302. Moreover, the conical structure of the first flow channel 600 also enables the first flow channel 600 to have a larger space to accommodate the mixed liquid, thereby preventing the mixed liquid from completely sealing the first flow channel 600, ensuring the connectivity between the inflow hole 400 and the second end 302, and enabling the fluid to enter the second end 302 through the inflow hole 400, thus breaking the siphon effect.

[0094] In an exemplary embodiment, please also combine Figure 4 and Figures 6 to 8 , the liquid storage mechanism 20 further has a second flow channel 700, and the second flow channel 700 is coaxially arranged with the first flow channel 600. The second flow channel 700 is connected between the inflow end 601 and the inflow hole 400. The second flow channel 700 can collect the fluid and uniformly convey the fluid to the first flow channel 600, ensuring the uniformity of the fluid flow rate and velocity in the first flow channel 600, and thus ensuring the uniformity of the mixing of the fluid and the foam liquid.

[0095] The inflow end 601 and the second flow channel 700 are arranged vertically one above the other, and the inflow hole 400 and the second flow channel 700 are arranged vertically one above the other, enabling the second flow channel 700 to have a certain ability to store the mixed liquid, further preventing the mixed liquid from isolating the inflow hole 400 from the second end 302 and affecting the fluid's breaking of the siphon effect.

[0096] In the embodiment of the present disclosure, the first flow channel 600 is relatively narrow compared to the second flow channel 700, which is beneficial for the fluid to first fill the second flow channel 700 during the foaming process, ensuring that the fluid can flow more uniformly towards the first flow channel 600. Moreover, the relatively narrow first flow channel 600 can exert extrusion on the fluid, separating the fluid into multiple airflows, further enhancing the mixing degree between the fluid and the foam liquid and forming a mixed liquid with numerous microbubbles.

[0097] The number of the inflow holes 400 can be multiple and they are evenly distributed along the second flow channel 700. The cross-sectional shape of the inflow hole 400 perpendicular to its axial direction includes but is not limited to regular shapes such as square, rectangle, triangle, circle, ellipse, trapezoid, semi-circle or semi-ellipse, etc. The cross-sectional shape of the inflow hole 400 perpendicular to its axial direction can also be an irregular shape.

[0098] In an exemplary embodiment, such as Figure 7As shown, the inlet hole 400 includes a main body portion 401 and a narrowing portion 402. The main body portion 401 is connected between the narrowing portion 402 and the second liquid distribution channel 700, and the narrowing portion 402 gradually narrows towards the main body portion 401. In this way, through the setting of the narrowing portion 402, the fluid entering the inlet hole 400 can be gradually compressed and accelerated, so that the fluid quickly passes through the main body portion 401 and rapidly diffuses to fill the second liquid distribution channel 700. Moreover, the structural settings of the main body portion 401 and the narrowing portion 402 also make the inlet hole 400 conducive to the entry of fluid and not conducive to the discharge of fluid, reducing the risk of the discharged fluid carrying the mixed liquid and discharging from the inlet hole 400.

[0099] In an exemplary embodiment, please continue to refer to Figure 7 , the liquid storage mechanism 20 further has a mixing chamber 800. The second end 302 is placed in the mixing chamber 800, and the outlet end 602 and the liquid outlet hole 500 are both connected to the second end 302 through the mixing chamber 800. In this way, through the setting of the mixing chamber 800, the mixing space between the foam liquid and the fluid can be increased, facilitating the fluid to cut the foaming agent from the circumferential direction of the foam liquid, and further improving the mixing uniformity. Moreover, after the foaming stops, the mixing chamber 800 can store the mixed liquid to prevent the mixed liquid from flowing back.

[0100] In an exemplary embodiment, please also refer to Figures 6 to 8 , the liquid storage mechanism 20 further has a mixing flow channel 900. The mixing flow channel 900 includes a first flow channel segment 901 and a second flow channel segment 902. The first flow channel segment 901, the mixing chamber 800, and the second end 302 are arranged in sequence from top to bottom in the vertical direction, which can reduce the difficulty of the mixed liquid entering the mixing flow channel 900, making the mixed liquid enter the mixing flow channel 900 more smoothly.

[0101] The second flow channel segment 902 is connected between the liquid outlet hole 500 and the first flow channel segment 901 and is inclined relative to the first flow channel segment 901. In this way, it is convenient to connect the liquid outlet hole 500 and the negative pressure mechanism 40 through a pipeline, and the hindering effect of gravity on the flow of the mixed liquid towards the negative pressure mechanism 40 is reduced. In the embodiment of the present disclosure, the first flow channel segment 901 and the second flow channel segment 902 are perpendicular to each other.

[0102] In an exemplary embodiment, please also refer to Figures 3 to 8 , the liquid storage mechanism 20 includes a first housing 21, a second housing 22, and a core 23. The liquid inlet hole 100 is arranged on the first housing 21, and the first housing 21 is provided with an installation groove 1000. The outer wall of the first housing 21 has a first joint 211, and the first joint 211 surrounds to form the liquid inlet hole 100. The setting of the first joint 211 can facilitate the connection of the liquid inlet hole 100 to the foam liquid storage unit 30 through a pipe structure 60 such as a hard pipe or a flexible pipe. The connection position 101 between the liquid inlet hole 100 and the liquid storage cavity 200 is located on the first housing 21.

[0103] The core body 23 is installed in the installation groove 1000 and encloses a liquid storage cavity 200 with the first housing 21. In this way, the structure of the liquid storage cavity 200 is stable, preventing external impurities from entering the liquid storage cavity 200 and ensuring the sealing performance of the liquid storage cavity 200, so that the foam liquid can flow along a preset path under the action of negative pressure. The drainage channel 300 is arranged in the core body 23. The outer wall of the core body 23 has a first insertion end 231 and a second insertion section 232. The first insertion end 231 encloses a first end 301. The second insertion section 232 encloses a second end 302. The first insertion end 231 can be placed in the liquid storage cavity 200. In addition, in some embodiments, the liquid storage cavity 200 can also be arranged in one of the core body 23 and the first housing 21. The core body 23 is installed in the installation groove 1000 and can be fixed to the first housing 21, ensuring the connection stability and position stability between the core body 23 and the first housing 21, and ensuring the connection stability among the liquid inlet hole 100, the liquid storage cavity 200 and the drainage channel 300 through the core body 23 and the first housing 21.

[0104] The second housing 22 is installed in the installation groove 1000 and is located on the side of the core body 23 away from the liquid storage cavity 200. The second housing 22 can enclose a mixing cavity 800, a first flow distribution channel 600 and a second flow distribution channel 700 with the core body 23.

In the embodiments of the present disclosure, the core body 23 has a conical outer wall. The second housing 22 has a conical inner wall, and the conical outer wall and the conical inner wall are in clearance fit to enclose the first flow distribution channel 600. In addition, in some embodiments, the second housing 22 can also be located at other positions of the core body 23. At least one of the mixing cavity 800, the first flow distribution channel 600 and the second flow distribution channel 700 can also be arranged in one of the second housing 22 and the core body 23. The second housing 22 is installed in the installation groove 1000 and can be fixed to the first housing 21 and the core body 23, ensuring the connection stability and position stability among the core body 23, the first housing 21 and the second housing 22, and ensuring the connection stability among the liquid inlet hole 100, the liquid storage cavity 200, the drainage channel 300, the mixing cavity 800, the first flow distribution channel 600 and the second flow distribution channel 700.

[0105] The outer wall of the second housing 22 has a second joint 221, and the second joint 221 encloses the liquid inlet hole 100. The arrangement of the second joint 221 can facilitate the connection of the liquid outlet hole 500 to the negative pressure mechanism 40 through a pipe structure 60 such as a rigid pipe or a flexible pipe.

[0106] It can be understood that in other embodiments, the liquid storage mechanism 20 can also be integrally formed.

[0107] In the exemplary embodiments, please also combine Figure 1 、 Figures 3 to 6 andFigure 8 On one side of the first housing 21 facing the mounting groove 1000, a clamping groove 1001 and a notch 1002 are provided.

[0108] On the circumferential outer side of the second housing 22, a clamping protrusion 222 is provided. The clamping protrusion 222 can move along the notch 1002 towards the core body 23 and can rotate relative to the first housing 21 with the second housing 22 to be clamped in the clamping groove 1001, clamping the core body 23 between the first housing 21 and the second housing 22. In this way, through the cooperation of the clamping protrusion 222 with the clamping groove 1001 and the notch 1002, the first housing 21 and the second housing 22 can be quickly disassembled and assembled conveniently, and the position of the core body 23 can be fixed, thereby ensuring the structural stability of the liquid storage cavity 200, the mixing cavity 800, the first flow distribution channel 600, and the second flow distribution channel 700.

[0109] In the embodiment of the present disclosure, the mounting groove 1000 can form a support surface 212 on the first housing 21.

The second housing 22 has an annular wall 223. The annular wall 223 is arranged around the core body 23 and can clamp the clamping wall 233 on the support surface 212. Sealing rings 70 are provided between the annular wall 223 and the core body 23 and between the annular wall 223 and the first housing 21.

[0110] The liquid storage mechanism 20 further includes a cover body 24. The cover body 24 is connected to the first housing 21 and covers the side of the second housing 22 away from the first housing 21. In this way, the cover body 24 and the first housing 21 can cooperate to protect the connection and cooperation position of the second housing 22 with the core body 23 and the first housing 21, ensuring the reliability of foaming and anti-backflow.

[0111] There is a flow channel 403 communicating with the inlet hole 400 between the cover body 24 and the first housing 21 and / or the second housing 22. In this way, through the setting of the cover body 24, the inlet hole 400 can also be protected, reducing the risk of the inlet hole 400 being blocked by impurities. The cover body 24 can be clamped to the first housing 21 and is connected to the electronic cover 10 through a connecting wall 241 provided on the cover body 24. In addition, in some embodiments, the liquid storage mechanism 20 may not include the cover body 24.
