When the water tank is connected to the base, the switch assembly is in the open state. When the water tank is separated from the base, the switch assembly is in the closed state.

[0005] For the humidifier of the embodiment of the utility model, when the water tank is connected to the base, the switch assembly is in the open state, so that the air outlet is in the open state. At this time, the water mist is discharged through the air outlet under the drive of the fan. When the water tank is separated from the base, the switch assembly is in the closed state, so that the air outlet is in the closed state. At this time, when the base is cleaned, the cleaning liquid (such as water) will not be accidentally added into the air outlet, thus avoiding damaging the electrical components inside the base.

[0006] Optionally, the switch assembly comprises a plugging member, an elastic member and a pushing member. The plugging member is movably arranged at the air outlet to switch between the open state and the closed state. The elastic member is connected to the plugging member, and the elastic member is used to provide an elastic force for the plugging member. The pushing member is connected to the water tank, and the pushing member is used to provide a pushing force for the plugging member. When the water tank is separated from the base, the plugging member switches to the closed state under the action of the elastic force. When the water tank is connected to the base, the plugging member switches to the open state under the action of the pushing force. Thus, when the water tank and the base are in different states, the opening or closing of the air outlet is automatically realized, which can more effectively avoid the cleaning liquid from being accidentally added into the air outlet.

[0007] Optionally, the plugging member is provided with a receiving cavity, and at least a part of the elastic member is arranged in the receiving cavity.

[0008] By providing a receiving cavity in the plugging member and arranging at least a part of the elastic member in the receiving cavity, the plugging member and the elastic member can share the same installation space, thereby reducing the occupied space of the switch assembly, avoiding excessive occupation of the internal space of the humidifier by the switch assembly, and facilitating the layout design of the internal components of the humidifier.

[0009] Optionally, the plugging member is movably arranged in the air duct in the up-down direction, the elastic member is used to provide an upward elastic force to the plugging member, and the pushing member is used to provide a downward pushing force to the plugging member.

[0010] In specific use, when the water tank is separated from the base, the plugging member moves to the closed state of closing the air outlet under the action of the upward elastic force; when the water tank is connected to the base, the pushing member pushes the plugging member downward, so that the plugging member moves downward to the open state of opening the air outlet. Thus, it is convenient for the switch assembly to switch between the plugged state and the closed state.

[0011] Optionally, the air outlet is arranged on the side wall of the air duct, and the upper part of the air duct has an insertion opening for the pushing member to be inserted; the plugging member includes a side plate and a top plate, the side plate is arranged on the lower side of the top plate and connected to the top plate, the top plate plugs the insertion opening, and the plugging member opens or closes the air outlet through the side plate.

[0012] By providing an insertion opening in the air duct, when the water tank is connected to the base, the pushing member is inserted into the air duct through the insertion opening, which is convenient for judging that the connection between the water tank and the base is in place and is beneficial to improving the user experience.

[0013] Optionally, the side plate is provided with a plugging portion and a communication port, and the communication port is arranged above the plugging portion; when the water tank is separated from the base, the plugging portion corresponds to the air outlet to close the air outlet, and when the water tank is connected to the base, the communication port corresponds to the air outlet to open the air outlet.

[0014] By providing a plugging portion and a communication port on the side plate, when the water tank is separated from the base, the plugging member moves upward under the elastic force of the elastic member, so that the plugging portion corresponds to the air outlet and the air outlet is plugged by the plugging portion; when the water tank is connected to the base, the plugging member moves downward under the pushing force of the pushing member, so that the communication port corresponds to the air outlet, and the air outlet is communicated with the internal components (such as the fog guide tube) of the water tank through the communication port. Thus, it is further convenient for the switch assembly to switch between the plugged state and the closed state.

[0015] Optionally, a plug rod is arranged in the air duct, and a jack is arranged on the top plate. When the water tank is connected to the base, the plug rod is in guiding cooperation with the jack.

[0016] By guiding and cooperating the insertion rod with the insertion hole, the moving direction of the plugging member can be guided to avoid the plugging member deviating from the moving path, thereby improving the reliability of the humidifier.

[0017] Optionally, a stop portion is provided at the upper part of the insertion rod, and the stop portion is used to abut downward against the top plate.

[0018] When the water tank is separated from the base, under the elastic force of the elastic member, the plugging member moves upward. When the stop portion abuts against the top plate, the plugging member is blocked by the stop portion and cannot move upward continuously. Thus, the plugging member is prevented from detaching from the insertion rod, improving the reliability of the humidifier.

[0019] Optionally, the stop portion is an elastic buckle.

[0020] By setting the stop portion as an elastic buckle, the elastic buckle can be elastically deformed to sleuth the plugging member on the insertion rod, realizing the assembly of the plugging member and the insertion rod, facilitating the installation of the plugging member, and being beneficial to further improving the assembly efficiency of the humidifier.

[0022] By providing a downward concave portion on the top plate, when the water tank is separated from the base and the plugging member moves upward under the elastic force of the elastic member, the stop portion can be located within the concave portion, so that a part of the plugging member can move to the upper side of the lower end of the stop portion. Thus, the occupied space of the switch assembly is reduced, the switch assembly is prevented from occupying too much internal space of the humidifier, and the layout design of the internal components of the humidifier is facilitated.

[0023] Optionally, the elastic member is a compression spring, the elastic member is sleeved on the insertion rod, and the upper part of the elastic member abuts upward against the top plate.

[0024] By sleeving the elastic member on the insertion rod, the elastic member can be radially limited without adding other components, facilitating the installation and fixation of the elastic member, and being beneficial to further improving the assembly efficiency of the humidifier.

[0025] Optionally, a receiving cavity is formed between the top plate and the side plate, and the lower end of the receiving cavity is open for the elastic member to be inserted into the receiving cavity.

[0026] Forming a receiving cavity between the top plate and the side plate can simplify the structure of the plugging member, facilitate the processing and manufacturing of the plugging member, and be beneficial to reducing the cost of the humidifier.

[0027] Optionally, the side plate is annular, and the side plate is in clearance fit with the side wall of the air duct.

[0028] By providing a clearance fit between the side plate and the side wall of the air duct, the moving direction of the plugging member can be guided, preventing the plugging member from deviating from the moving path and improving the reliability of the humidifier.

[0029] Optionally, the base includes a base body and a housing. The base body is detachably connected to the housing.

[0048] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation of the present invention.

[0049] As Figures 1 to 3 shown, the humidifier 100 of the embodiment of the present invention includes a base 1, a fan 2, a water tank 6 and a switch assembly. The base 1 is provided with an air duct 11 and an air outlet 12 communicated with the air duct 11. The fan 2 is arranged inside the air duct 11. The water tank 6 is detachably connected to the base 1. As Figures 6 to 11 shown, the switch assembly is arranged at the air outlet 12, and the switch assembly can be switched between an open state of opening the air outlet 12 and a closed state of closing the air outlet 12. Among them, when the water tank 6 is connected to the base 1, the switch assembly is in an open state; when the water tank 6 is separated from the base 1, the switch assembly is in a closed state.

[0050] For the humidifier 100 of the embodiment of the present invention, when the water tank 6 is connected to the base 1, the switch assembly is in an open state, so that the air outlet 12 is in an open state. At this time, the water mist is discharged through the air outlet 12 under the drive of the fan 2; when the water tank 6 is separated from the base 1, the switch assembly is in a closed state, so that the air outlet 12 is in a closed state. At this time, the base 1 is cleaned, and the cleaning liquid (such as water) will not be accidentally added into the air outlet 12, thereby avoiding damage to the electrical components inside the base 1.

[0051] In some embodiments, as Figures 3 to 11As shown, the switch assembly includes a plugging member 3, an elastic member 4, and a pushing member 7. The plugging member 3 is movably arranged at the air outlet 12 to switch between an open state and a closed state. The elastic member 4 is connected to the plugging member 3, and the elastic member 4 is used to provide an elastic force to the plugging member 3. The pushing member 7 is connected to the water tank 6, and the pushing member 7 is used to provide a pushing force to the plugging member 3. Wherein, when the water tank 6 is separated from the base 1, the plugging member 3 switches to the closed state under the action of the elastic force; when the water tank 6 is connected to the base 1, the plugging member 3 switches to the open state under the action of the pushing force.

[0052] By setting the switch assembly to include the plugging member 3, the elastic member 4, and the pushing member 7, when the water tank 6 is separated from the base 1, the plugging member 3 automatically switches to the closed state of closing the air outlet 12 under the elastic force of the elastic member 4; when the water tank 6 is connected to the base 1, the plugging member 3 automatically switches to the open state of opening the air outlet 12 under the pushing force of the pushing member 7. Thus, when the water tank 6 and the base 1 are in different states, the opening or closing of the air outlet 12 is automatically realized, which can more effectively avoid the cleaning liquid being accidentally added into the air outlet 12.

[0053] As Figure 1 shown, the humidifier 100 includes a base assembly 10 and a water tank assembly 20. Wherein, the base assembly 10 includes the above-mentioned base 1, a blower 2, a plugging member 3, and an elastic member 4; the water tank assembly 20 includes the above-mentioned water tank 6 and a pushing member 7.

[0054] Optionally, the pushing member 7 is integrally formed with the water tank 6.

[0055] Optionally, the plugging member 3 is movably arranged in the air duct 11 in the up-down direction. The elastic member 4 is used to provide an upward elastic force to the plugging member 3, and the pushing member 7 is used to provide a downward pushing force to the plugging member 3. Wherein, the up-down direction is as Figures 1 to 11 shown.

[0056] During specific use, when the water tank 6 is separated from the base 1, the plugging member 3 moves to the closed state of closing the air outlet 12 under the upward elastic force; when the water tank 6 is connected to the base 1, the pushing member 7 pushes the plugging member 3 downward, so that the plugging member 3 moves downward to the open state of opening the air outlet 12. Thus, it is convenient for the switch assembly to switch between the plugging state and the closed state.

[0057] Optionally, the air outlet 12 is arranged on the side wall of the air duct 11. The upper part of the air duct 11 has an insertion opening 114 for the pushing member 7 to insert. The plugging member 3 includes a side plate 32 and a top plate 33. The side plate 32 is arranged under the top plate 33 and connected to the top plate 33. The top plate 33 plugs the insertion opening 114, and the plugging member 3 opens or closes the air outlet 12 through the side plate 32.

[0058] When the water tank 6 is connected to the base 1, the pushing member 7 is inserted into the air duct 11 through the insertion interface 114, and then pushes the blocking member 3 downward, and opens the air outlet 12 through the side plate 32; when the water tank 6 is separated from the base 1, the pushing member 7 is pulled out through the insertion interface 114, and the blocking member 3 moves under the elastic force of the elastic member 4, and closes the air outlet 12 through the side plate 32.

[0059] By providing the insertion interface 114 in the air duct 11, when the water tank 6 is connected to the base 1, the pushing member 7 is inserted into the air duct 11 through the insertion interface 114, which is convenient for judging that the connection between the water tank 6 and the base 1 is in place, and is beneficial to improving the user experience.

[0060] Optionally, as Figures 6 to 11 shown, the side plate 32 is provided with a blocking portion 321 and a communication port 322, and the communication port 322 is provided above the blocking portion 321. When the water tank 6 is separated from the base 1, the blocking portion 321 is arranged corresponding to the air outlet 12 to close the air outlet 12. When the water tank 6 is connected to the base 1, the communication port 322 is arranged corresponding to the air outlet 12 to open the air outlet 12.

[0061] By providing the blocking portion 321 and the communication port 322 on the side plate 32, when the water tank 6 is separated from the base 1, the blocking member 3 moves upward under the elastic force of the elastic member 4, so that the blocking portion 321 is arranged corresponding to the air outlet 12, and the blocking portion 321 is used to block the air outlet 12; when the water tank 6 is connected to the base 1, the blocking member 3 moves downward under the pushing force of the pushing member 7, so that the communication port 322 is arranged corresponding to the air outlet 12, and the air outlet 12 is communicated with the components (such as the fog guide pipe) inside the water tank 6 through the communication port 322. Thus, it is further convenient for the switching assembly to switch between the blocking state and the closing state.

[0062] Optionally, as Figures 3 to 5 shown, a plug rod 113 is provided in the air duct 11, and a jack 331 is provided on the top plate 33. As Figure 7 and Figure 9 shown, when the water tank 6 is connected to the base 1, the plug rod 113 is in guiding cooperation with the jack 331.

[0063] By using the guiding cooperation between the plug rod 113 and the jack 331, the moving direction of the blocking member 3 can be guided, avoiding the blocking member 3 from deviating from the moving path, and improving the reliability of the humidifier 100.

[0064] Optionally, as Figure 4 、 Figure 7 、 Figure 9 and Figure 11 shown, a stop portion 1131 is provided on the upper part of the plug rod 113, and the stop portion 1131 is used to stop against the top plate 33 downward.

[0065] When the water tank 6 is separated from the base 1, under the elastic force of the elastic member 4, the plugging member 3 moves upward until the blocking portion 1131 abuts against the top plate 33. At this time, the plugging member 3 is blocked by the blocking portion 1131 and cannot move upward continuously. Thus, the plugging member 3 is prevented from detaching from the insertion rod 113, improving the reliability of the humidifier 100.

[0066] Optionally, the blocking portion 1131 is an elastic buckle.

[0067] By setting the blocking portion 1131 as an elastic buckle, the elastic buckle can be elastically deformed to sleeved the plugging member 3 on the insertion rod 113, realizing the assembly of the plugging member 3 and the insertion rod 113, facilitating the installation of the plugging member 3, and being beneficial to further improving the assembly efficiency of the humidifier 100.

[0068] Optionally, as Figure 7 、 Figure 9 and Figure 11 shown, the top plate 33 is provided with a downward concave portion 332, and the insertion hole 331 is arranged on the concave portion 332. The concave portion 332 is used to accommodate the blocking portion 1131.

[0069] As Figure 11 shown, by providing a downward concave portion 332 on the top plate 33, when the water tank 6 is separated from the base 1 and the plugging member 3 moves upward under the elastic force of the elastic member 4, the blocking portion 1131 can be located in the concave portion 332, so that a part of the plugging member 3 can move to the upper side of the lower end of the blocking portion 1131. Thus, the occupied space of the switch assembly is reduced, avoiding the switch assembly occupying too much internal space of the humidifier 100, and facilitating the layout design of the internal components of the humidifier 100.

[0070] Optionally, as Figure 3 、 Figure 7 and Figure 9 shown, the elastic member 4 is a compression spring. The elastic member 4 is sleeved on the insertion rod 113, and the upper part of the elastic member 4 abuts upward against the top plate 33.

[0071] By sleeving the elastic member 4 on the insertion rod 113, the elastic member 4 can be radially limited without adding other components, facilitating the installation and fixation of the elastic member 4, and being beneficial to further improving the assembly efficiency of the humidifier 100.

[0072] Optionally, as Figure 5 、 Figure 7 、 Figure 9 and Figure 11 shown, the plugging member 3 is provided with a receiving cavity 31, and at least a part of the elastic member 4 is arranged in the receiving cavity 31.

[0073] By providing a receiving cavity 31 in the plugging member 3 and disposing at least a part of the elastic member 4 within the receiving cavity 31, the plugging member 3 and the elastic member 4 can share the same installation space, thereby reducing the occupied space of the switch assembly and preventing the switch assembly from overly occupying the internal space of the humidifier 100, facilitating the layout design of the internal components of the humidifier 100.

[0074] Optionally, as Figure 5 , Figure 7 , Figure 9 and Figure 11 shown, a receiving cavity 31 is defined between the top plate 33 and the side plate 32, and the lower end of the receiving cavity 31 is open to allow the elastic member 4 to be inserted into the receiving cavity 31.

[0075] Defining the receiving cavity 31 between the top plate 33 and the side plate 32 can simplify the structure of the plugging member 3, facilitate the processing and manufacturing of the plugging member 3, and help reduce the cost of the humidifier 100.

[0076] Optionally, as Figure 5 , Figure 7 , Figure 9 and Figure 11 shown, the side plate 32 is annular and is in clearance fit with the side wall of the air duct 11.

[0077] For example, as Figure 5 shown, the side plate 32 is in the shape of a rectangular ring.

[0078] By providing a clearance fit between the side plate 32 and the side wall of the air duct 11, the moving direction of the plugging member 3 can be guided to prevent the plugging member 3 from deviating from the moving path, improving the reliability of the humidifier 100.

[0079] As Figure 2 and Figure 9 shown, the pushing member 7 is a push rod, and the number of pushing members 7 is multiple. The multiple pushing members 7 are arranged at intervals around the circumference of the insertion rod 113.

[0080] For example, the number of pushing members 7 is two, and the two pushing members 7 are disposed on opposite sides of the insertion rod 113.

[0081] As Figure 2 shown, the water tank 6 includes a box body 61 and a top cover 62. The box body 61 is connected to the top cover 62, and the pushing member 7 is disposed at the lower part of the box body 61. Among them, the box body 61 and the top cover 62 can be connected by snap fasteners.

The blower chamber 112 communicates with the installation chamber 111 and encloses an air duct 11.

[0083] Wherein, a partition plate may be provided between the installation chamber 111 and the blower chamber 112, and through holes are arranged on the partition plate, so that the installation chamber 111 and the blower chamber 112 communicate through the through holes. The base body 101 and the housing 102 may be connected by snap fasteners.

[0084] By providing the blower chamber 112 on the base body 101 and the installation chamber 111 on the housing 102, when assembling the humidifier 100, the blower 2 can be first installed in the blower chamber 112 of the base body 101, the plugging member 3 and the elastic member 4 are arranged in the installation chamber 111, and then the base body 101 and the housing 102 are connected. Thus, not only can the interference between the switch assembly and the blower 2 be avoided, but also the assembly of each component is convenient, which is beneficial to improving the assembly efficiency of the humidifier 100.
