[0063] The water tank assembly (110) is connected to an external water circuit and comprises a box body (111), a water storage chamber (112) arranged in the box body (111), and a water replenishment pipeline (113) and a drainage pipeline (114) connected to the water storage chamber (112); the water replenishment pipeline (113) is connected to the external water circuit and is connected to a water replenishment switch (1132); the drainage pipeline (114) is connected to an external wastewater collection device and is provided with a drainage switch (1141).

[0064] In this embodiment, the water replenishment switch (1132) and the drainage switch (1141) are solenoid valves, wherein the drainage switch (1141) is preferably a piston-type solenoid valve.

[0065] In this embodiment, a drainage pump (1142) is connected to the drainage pipeline (114). Specifically, the drainage pump (1142) is arranged between the water storage chamber (112) and the drainage switch (1141); the drainage pump (1142) is preferably an impeller pump.

[0066] In this embodiment, the inner diameter of the drainage pipe (114) is preferably greater than 10 mm to ensure smooth drainage.

[0067] In this embodiment, the water replenishment pipeline (113) is connected to an external water channel, such as a tap water pipe, and the drainage pipeline (114) is connected to an external wastewater collection device, such as a sewer outlet (1143). The water tank assembly (110) can realize automatic water replenishment and automatic drainage, eliminating the need for users to manually add water and manually pour water, making users more worry-free and greatly improving the user experience.

[0068] The self-cleaning component (120) is connected to the water storage chamber (112), and includes a cleaning chamber (121), and a cleaning pipeline (122) connected between the cleaning chamber (121) and the water storage chamber (112), and a cleaning pump (1221) is provided on the cleaning pipeline (122). In this embodiment, the cleaning chamber (121) is used to store cleaning liquid, and the cleaning liquid in the cleaning chamber (121) is transported to the water storage chamber (112) along the cleaning pipeline (122) by the cleaning pump (1221), thereby realizing automatic cleaning, eliminating the need for users to manually clean the cleaning liquid regularly, and saving time and effort. Specifically, the cleaning liquid is preferably a liquid citric acid descaling agent; the cleaning pump (1221) is preferably a small flow peristaltic pump, which has good corrosion resistance and accurate flow, and can better control the dosage of the cleaning liquid.

[0069] The detection assembly (130) comprises a liquid level detection module (131) for detecting the liquid level state in the water storage chamber (112), and a water quality sensor (132) for detecting the water quality state in the water storage chamber (112); the liquid level detection module (131) comprises a high liquid level detector (1311), a low liquid level detector (1312), and a triggering member (1313) cooperating with the high liquid level detector (1311) and the low liquid level detector (1312) to detect the liquid level height in the water storage chamber (112).

[0070] In this embodiment, the high liquid level detector (1311) and the low liquid level detector (1312) are fixed on the same side of the side wall of the water storage chamber (112) and are arranged side by side along the gravity direction. The trigger member (1313) is suspended on the liquid surface in the water storage chamber (112) and floats freely along the gravity direction according to the liquid level. When the trigger member (1313) approaches the high liquid level detector (1311) or the low liquid level detector (1312), the high liquid level detector (1311) or the low liquid level detector (1312) is triggered and sends a trigger signal to the control component (160).

[0071] In this embodiment, the water quality sensor (132) includes a TDS probe (1321) for detecting the TDS value of the raw water in the water storage chamber (112). During the operation of the air humidification device, the raw water in the water storage chamber (112) is continuously evaporated, and the soluble substances in the water, such as calcium ions, magnesium ions, potassium ions, sodium ions, etc., are retained in the water storage chamber (112), resulting in a gradual increase in the concentration of soluble substances in the raw water in the water storage chamber (112), thereby generating scale, which affects the user experience and filter life of the air humidification device. The TDS probe (1321) detects the TDS value of the raw water in the water storage chamber (112) in real time and sends a signal to the control component (160). When the TDS value growth rate exceeds a preset value, the cleaning chamber (121) starts the self-cleaning operation.

[0072] The control component (160) is used to receive signals from the liquid level detection module (131) and control the automatic water replenishment / automatic drainage of the water storage chamber (112), and is also used to receive signals from the water quality sensor (132) and control the automatic cleaning of the water storage chamber (112).

[0073] The humidifying component (140) is connected to the water storage chamber (112), and comprises a humidifying net (141) arranged above the water storage chamber (112), and a water supply pipeline (142) connected between the water storage chamber (112) and the humidifying net (141). A water supply pump (1421) is arranged on the water supply pipeline (142). The raw water in the water storage chamber (112) flows through the humidifying net (141) through the water supply pipeline (142) and flows back to the water storage chamber (112).

[0074] In this embodiment, the output end of the water adding pipeline (142) is detachably connected to the humidifying net (141), so that the user can take out the water adding pipeline (142) and the water adding pump (1421) separately to clean the inner wall of the water storage chamber (112).

[0075] In this embodiment, a return water box (143) is provided on the upper surface of the water storage chamber (112), and the humidifying net (141) is provided above the return water box (143). The raw water flowing through the humidifying net (141) flows back to the water storage chamber (112) along the return water box (143). The return water box (143) is provided to recycle the raw water flowing through the humidifying net (141), thereby realizing the recycling of water resources.

[0076] In this embodiment, a filter screen (144) is provided below the return water box (143) to filter the raw water recovered in the return water box (143). The raw water filtered by the filter screen (144) enters the water storage chamber (112) for recycling.

[0077] In this embodiment, the filter screen (144) is detachably connected to the water return box (143) to facilitate regular replacement of the filter screen (144).

[0078] The fan assembly (150) is used to drive air to form an airflow and flow through the humidifying net (141) to humidify the air. In this embodiment, the fan assembly (150) is arranged above the humidifying assembly (140), and the external air passes through the humidifying assembly (140) through the fan assembly (150), and then is discharged to the outside of the air humidifier through the fan assembly (150).

[0079] It can be understood that the air humidifying device (100) with self-cleaning function in this embodiment further includes a housing (170) and a cover plate (171). Preferably, this embodiment further includes an air purification filter (172) disposed at the air inlet of the air humidifying device.

[0080] Combination Figure 4In a more preferred embodiment, the water replenishment pipeline (113) is movably connected to a water stopper (115) at one end of the water storage chamber (112), and the water stopper (115) is suspended above the liquid surface in the water storage chamber (112), and seals the output end of the water replenishment pipeline (113) as the liquid level rises to the top of the water storage chamber (112). In actual application, when the high liquid level detector (1311) is damaged, it is impossible to send a trigger signal to the control component (160) in time to stop water replenishment, and continuous water inflow into the water storage chamber (112) will cause water to overflow, resulting in a poor user experience. In this embodiment, the water replenishment action is stopped by the water stopper (115), which can avoid the problem of overflow caused by continuous water inflow into the water storage chamber (112) due to failure of the high liquid level detector (1311).

[0081] In a more preferred embodiment, the water stop member (115) includes a water stop float (1151) and a connecting rod (1152) connected to one end of the water stop float (1151), and the other end of the connecting rod (1152) is contact-connected to the output end of the water supply pipeline (113) via a rotating shaft; the water stop float (1151) is suspended on the liquid surface in the water storage chamber (112), and floats freely along the direction of gravity with the height of the liquid level, while driving the connecting rod (1152) to rotate. When the liquid level in the water storage chamber (112) is low, the water stop float (1151) is in a low position, at which point the connecting rod (1152) is connected to the output end connection of the water supply pipeline (113), and the water supply pipeline (113) can supply water to the water storage chamber (112); when the liquid level in the water storage chamber (112) approaches the top of the water storage chamber (112), the water stop float (1151) rises to the top of the water storage chamber (112), at which point the connecting rod (1152) is closed to the output end connection of the water supply pipeline (113), and the water supply pipeline (113) cannot supply water to the water storage chamber (112).

[0082] It can be understood that when the water stop member (115) seals the output end of the water supply pipeline (113), the liquid level in the water storage chamber (112) is higher than the liquid level when the high liquid level detector (1311) is triggered.

[0083] In a more preferred embodiment, the water supply pipeline (113) is further provided with a high pressure switch (1133) and a one-way valve (1134) provided between the high pressure switch (1133) and the water storage chamber (112). The high pressure switch (1133) is used to detect the water pressure in the water supply pipeline (113) and send a water pressure signal to the control component (160). Specifically, when the connection between the connecting rod (1152) and the output end of the water supply pipeline (113) is closed, the water pressure in the water supply pipeline (113) is high and exceeds a preset value, the high-pressure switch (1133) sends a signal to the control component (160), and the control component (160) controls the high-pressure switch (1133) to close to stop water supply; when the connection between the connecting rod (1152) and the output end of the water supply pipeline (113) is connected, the water pressure in the water supply pipeline (113) is low and does not exceed the preset value, the high-pressure switch (1133) sends a signal to the control component (160), and the control component (160) controls the high-pressure switch (1133) to connect to replenish water. The one-way valve (1134) is used to control the raw water in the water supply pipeline (113) to flow in one direction along the three-way pipe (1131) to the water storage chamber (112) to prevent backflow. Specifically, during the water replenishment process, the raw water in the water replenishment pipeline (113) continuously replenishes the water storage chamber (112), the liquid level in the water storage chamber (112) is in a non-static state, and the water stop float (1151) floats along the gravity direction with the liquid level, driving the connection between the connecting rod (1152) and the output end of the water replenishment pipeline (113) to repeatedly connect / close and switch, resulting in an unstable water pressure signal detected by the high-pressure switch (1133); a one-way valve (1134) is provided between the high-pressure switch (1133) and the water storage chamber (112), so as to prevent the water in the water storage chamber (112) from flowing back to the high-pressure switch (1133), so as to ensure that the high-pressure switch (1133) outputs a stable water pressure signal.

[0084] In conjunction with Figures 5(a), 5(b), and 5(c), in a more preferred embodiment, the cleaning pipeline (122) is provided with a spray device (123) at one end connected to the water storage chamber (112), and the spray device (123) is fixed to the top periphery of the water storage chamber (112), and spray holes facing the water storage chamber (112) are evenly provided along the perimeter direction. Specifically, water containing cleaning liquid is transported to the water storage chamber (112) along the cleaning pipeline (122), and is sprayed into the water storage chamber (112) along the spray holes through the spray device (123), so that the water storage chamber (112) is fully cleaned and cleaned more fully.

[0085] In a more preferred embodiment, the spray holes include an outer spray hole (1231) facing the side wall of the water storage chamber (112), and an inner spray hole (1232) facing the bottom of the water storage chamber (112), and the outer spray hole (1231) and the inner spray hole (1232) are distributed at intervals. Specifically, water containing cleaning liquid is sprayed out from the outer spray hole (1231) to clean the side wall of the water storage chamber (112), and is sprayed out from the inner spray hole (1232) to clean the bottom of the water storage chamber (112).

[0086] In a more preferred embodiment, the self-cleaning component (120) further comprises a dilution chamber (124) disposed between the cleaning pump (1221) and the water storage chamber (112), and a dilution pipeline (125) connected between the dilution chamber (124) and the external water circuit, and a dilution switch (1251) is disposed on the dilution pipeline (125). Specifically, in this embodiment, the cleaning liquid is diluted and mixed by the dilution chamber (124) before entering the water storage chamber (112), so as to improve the cleaning efficiency.

[0087] In a more preferred embodiment, the upper end surface of the cleaning chamber (121) is provided with a liquid injection hole (1211) and a liquid injection cover (1212) cooperating with the liquid injection hole (1211), and the cleaning liquid can be added to the cleaning chamber (121) through the liquid injection hole (1211), and the liquid injection cover (1212) is used to seal the liquid injection hole (1211) to prevent dust.

[0088] In a more preferred embodiment, a liquid level sensor (1213) is provided at the bottom of the cleaning chamber (121) to detect the level of the cleaning liquid in the cleaning chamber (121). Specifically, when the level of the cleaning liquid in the cleaning chamber (121) is lower than a critical value, the liquid level sensor (1213) sends a signal to the control component (160) to remind the user to add cleaning liquid.

[0089] In a more preferred embodiment, the liquid level sensor (1213) includes any one of a capacitive sensor, a photoelectric sensor, an ultrasonic sensor, or an infrared sensor.
