Description

Technical Field

[0001] The present application relates to the technical field of air humidification electrical appliances, and in particular to a humidification device. Background Art

[0002] A humidifier is a device used to adjust the humidity of the air. According to different working principles, humidifiers can be divided into three categories: electric heating humidifiers, ultrasonic humidifiers and evaporative humidifiers. Evaporative humidifiers are becoming more and more popular among consumers because of their low water quality requirements and energy saving.

[0003] An evaporative humidifier usually includes a main unit and a water tank. The main unit includes a housing and a fan. The fan is arranged inside the housing. A filter is arranged inside the water tank. The filter is used to absorb moisture. The fan guides the airflow through the filter and blows it out, so that the airflow carries water vapor and is blown out of the humidifier to achieve the purpose of humidifying the air. After the fan has been running for a period of time, a lot of dust will be absorbed on the blades of the fan. After the dust absorbs the wet mist, it is easy to breed a large number of bacteria. If it is not cleaned in time, it will affect the normal operation of the fan and the cleanliness of the humidifier. However, the fans in the related art are all installed in the housing in an undetachable manner, which makes it inconvenient to clean the blades. Utility Model Content

[0004] Based on this, the present application provides a humidification device to solve the deficiencies in the related art.

[0005] The humidifying device provided in the present application comprises a humidifying main unit and a water tank assembly, the water tank assembly comprises a water tank, the humidifying main unit is connected to the water tank, and the humidifying main unit comprises a shell and a fan assembly, the shell has an air cavity connected to the water tank, the air cavity has an air outlet, and the fan assembly is located on a side of the air cavity facing the air outlet;

[0006] The fan assembly includes a motor, an impeller and a limit unit, the limit unit includes a limit piece and a limit shaft, the motor includes a stator and a rotor sleeve, the stator is fixed to the wind chamber, the rotor sleeve cover is arranged on the outside of the stator, the circumferential side wall of the rotor sleeve is provided with a first limit portion, the impeller sleeve is arranged on the outside of the circumferential side wall of the rotor sleeve, and the first limit portion is constructed to fix the impeller in the circumferential direction of the rotor sleeve, the limit shaft is installed on the rotor sleeve along the rotation axis of the rotor sleeve, the limit piece and the limit shaft are tightly connected, and the limit piece stops on the side of the impeller facing the air outlet.

[0007] The humidifying device of the embodiment of the present application is provided with a water tank for containing humidifying liquid, an air outlet cavity for installing a fan assembly, an air outlet for allowing wet mist to flow out, a stator for forming an electromagnetic field to drive the stator sleeve to rotate, a rotor sleeve to drive the impeller 122 to rotate synchronously, an impeller for driving air flow so that the air carries the humidifying liquid out, a first limiting portion is provided to limit the circumferential position of the impeller on the rotor sleeve to prevent the impeller 122 from rotating relative to the rotor sleeve, and the impeller and the rotor sleeve can be detachable at the same time, a limiting shaft and a limiting member are provided to limit the axial position of the impeller on the rotor sleeve to prevent the impeller from detaching from the rotor sleeve when rotating, and the limiting member and the limiting shaft can be detachable. With such a configuration, when the impeller needs to be disassembled, the limiting member can be conveniently removed from the limiting shaft, and the impeller can be removed from the rotor sleeve, so as to facilitate the disassembly and installation of the impeller, thereby facilitating the cleaning of the impeller.

[0008] In one possible implementation, the humidification device provided in the present application has a first axial hole on the side of the rotor sleeve facing the air outlet, the first axial hole is located on the rotation axis of the rotor sleeve, the limit shaft is installed in the first axial hole, and the limit shaft and the rotor sleeve are relatively fixed in the axial direction of the rotor sleeve.

[0009] In this way, the limiting shaft can be installed on the rotor sleeve through the first shaft hole, and then the impeller is sleeved on the rotor sleeve after passing through the limiting shaft, so that the axial displacement of the impeller in the rotor sleeve can be limited by the limiting member.

[0010] In a possible implementation, in the humidification device provided in the present application, the limiting shaft is engaged with the first shaft hole along the axial direction of the rotor sleeve; or, the limiting shaft and the hole wall of the first shaft hole are interference fit.

[0011] In this way, the limiting shaft and the rotor sleeve can be relatively fixed in the axial direction of the rotor sleeve, or the limiting shaft and the rotor sleeve can be relatively fixed in both the axial direction and the circumferential direction of the rotor sleeve.

[0012] In a possible implementation, the humidification device provided in the present application extends the limiting axis toward the air outlet so as to extend out of the end surface of the rotor sleeve facing the air outlet.

[0013] In this way, the limit shaft can extend out of the first shaft hole so that the limit member can be fastened to the end of the limit shaft away from the rotor sleeve, thereby making the limit member stop on the side of the impeller facing the air outlet to prevent the impeller from moving axially relative to the rotor sleeve along the rotor sleeve.

[0014] In a possible implementation, in the humidification device provided in the present application, a mounting seat is provided in the air cavity, and the mounting seat is constructed to support the motor.

[0015] In this way, the stator of the motor can be fixed relative to the housing, and the rotor sleeve can rotate relative to the stator, thereby driving the impeller to rotate synchronously.

[0016] In one possible implementation, the humidifier device provided in the present application, the limit member includes a hand-held portion and a threaded connection portion that are interconnected, the threaded connection portion has an internal thread, and the end of the limit shaft away from the rotor sleeve has an external thread that matches the internal thread, so that the threaded connection portion is threadedly connected to the limit shaft.

[0017] In this way, by threading the limiting member and the limiting shaft, it is beneficial to improve the installation efficiency and disassembly efficiency of the impeller, and improve the connection reliability between the limiting member and the limiting shaft.

[0018] In a possible implementation, the humidification device provided in the present application, the impeller includes a mounting tube and blades connected to the outer peripheral wall of the mounting tube, and the end of the mounting tube facing away from the air outlet has an opening so that it can be mounted on the outer side of the rotor sleeve through the opening.

[0019] In this way, the rotor sleeve can drive the installation tube to rotate, and then drive the blades to rotate synchronously, thereby driving the air flow. When the impeller needs to be installed and removed, it is only necessary to connect the rotor sleeve through the opening along the axial direction of the rotor sleeve, and pull the impeller out of the rotor sleeve along the axial direction of the rotor sleeve through the opening. The installation and disassembly of the impeller is relatively convenient.

[0020] In one possible implementation, the humidification device provided in the present application has an end surface portion at the end of the mounting cylinder opposite to the opening, and the end surface portion has a first mounting hole coaxially arranged with the rotation axis of the rotor sleeve, and the limiting shaft is sequentially passed through the first axial hole and the first mounting hole.

[0021] In this way, when the limit member is fastened to the limit shaft and stops on the side of the impeller facing the air outlet, the end surface portion can abut against the rotor sleeve, and then the limit member abuts against the end surface portion, which can effectively limit the impeller from moving relative to the rotor sleeve along the axial direction of the rotor sleeve.

[0022] In a possible implementation, in the humidification device provided in the present application, the limiting shaft is a non-circular shaft, and the shape of the first mounting hole matches the cross-sectional shape of the limiting shaft.

[0023] In this way, when the rotor sleeve rotates, it can drive the impeller and the limit shaft to rotate synchronously to avoid relative rotation between the limit shaft and the first mounting hole, which would cause greater wear on the limit shaft or the first mounting hole. When the impeller needs to be disassembled, the first mounting hole can also be easily separated from the limit shaft.

[0024] In one possible implementation, in the humidification device provided in the present application, the inner side wall of the mounting cylinder has a second limiting portion that matches the first limiting portion, and the second limiting portion and the first limiting portion are mutually engaged in the circumferential direction of the rotor sleeve to limit the relative rotation of the mounting cylinder and the rotor sleeve in the circumferential direction.

[0025] In this way, by the mutual engagement of the first limiting portion and the second limiting portion, the position of the mounting cylinder on the rotor sleeve in the circumferential direction can be limited to prevent the impeller and the rotor sleeve from rotating relative to each other, thereby allowing the rotor sleeve to drive the impeller to rotate synchronously.

[0026] In a possible implementation, in the humidification device provided in the present application, one of the first limiting portion and the second limiting portion is a convex rib extending axially along the rotor sleeve, and the other is a sliding groove matching the shape of the convex rib.

[0027] In this way, the rib and the slide groove are engaged to effectively limit the rotation of the mounting tube relative to the rotor sleeve, and when the impeller is removed, the slide groove can be made to slide relative to the rib along the axial direction of the rotor sleeve, or the rib can be made to slide relative to the slide groove along the axial direction of the rotor sleeve, thereby conveniently removing the impeller from the rotor sleeve.

[0028] In one possible implementation, the humidifier device provided in the present application, the motor also includes a rotating shaft, the rotor sleeve has a second axial hole on the side facing away from the limiting shaft, the first end of the rotating shaft is connected to the second axial hole, the second end is rotatably arranged on the stator, and the rotating shaft, stator and rotor sleeve are relatively fixed in the axial direction of the rotor sleeve.

[0029] In this way, when the stator is energized, an electromagnetic field is generated, which can drive the shaft to rotate relative to the stator, and then drive the rotor sleeve to rotate relative to the stator through the rotor, so as to output torque through the rotor sleeve to drive the impeller to rotate.

[0030] In a possible implementation, in the humidification device provided in the present application, the stator is sleeved on the mounting seat, the mounting seat has a second mounting hole, and the second end of the rotating shaft is rotatably connected to the second mounting hole through a bearing member.

[0031] In this way, the stator can be fixedly installed in the wind cavity, and the second end of the rotating shaft can be rotatably set on the stator, so that the rotating shaft, stator and rotor sleeve are relatively fixed in the axial direction of the rotor sleeve, and the rotating shaft and rotor sleeve can rotate relative to the stator.

[0032] In a possible implementation, the humidification device provided in the present application, the humidification host also includes an air outlet net, the air outlet net cover is arranged at the air outlet, and the air outlet net is detachably connected to the shell.

[0033] In this way, the air outlet net can allow air to circulate while preventing other foreign objects from entering the air cavity to avoid affecting the rotation of the impeller. At the same time, by opening the air outlet net, the fan assembly can be exposed to facilitate the removal of the impeller.

[0034] In a possible implementation, the humidification device provided in the present application also includes a magnetic attraction component, which includes a first magnetic component and a second magnetic component. The first magnetic component is arranged on the air outlet net, and the second magnetic component is arranged on the shell, so that the air outlet net is magnetically connected to the shell.

[0035] In this way, when no external force is applied, the first magnetic part and the second magnetic part are magnetically attracted to each other, so that the air outlet net is reliably covered on the air outlet. When the air outlet net needs to be opened, only a small force needs to be applied to disengage the first magnetic part and the second magnetic part from the magnetic connection, thereby allowing the air outlet net to open the air outlet, so as to facilitate the removal of the impeller located in the air chamber.

[0036] In a possible implementation, the humidification device provided in the present application also includes an electric switch component, the motor is electrically connected to the electric switch component, the electric switch component is connected to the side of the mounting base facing away from the air outlet, and the electric switch component is constructed to cut off power to the motor when the shell is separated from the water tank.

[0037] In this way, before the impeller needs to be removed for cleaning, the humidifier host can be disconnected from the water tank. At this time, the electrical switch can automatically cut off the power supply to the motor and the impeller stops rotating, so that it is safer for the user to remove the impeller later.

[0038] In a possible implementation, the humidifying device provided by the present application, the water tank assembly further includes a water absorbing member, a float and a float bracket, the side wall of the water tank has an air inlet hole, the water absorbing member is disposed in the water tank and is configured to absorb the humidifying liquid in the water tank;

[0039] The float bracket is located in the water absorbing member and connected to the inner bottom wall of the water tank. The float bracket has a floating cavity. The float is arranged in the floating cavity and is constructed to trigger the electric switch when the liquid level in the water tank is higher than or equal to a preset liquid level.

[0040] In this way, the water absorbent absorbs the humidifying liquid in the water tank, and the surface of the water absorbent can form a larger evaporation surface, and under the action of the fan assembly, the air is driven to circulate, so that the air carries the humidifying liquid on the evaporation surface and blows it out, thereby forming water mist, thereby increasing the air humidity of the surrounding environment. The float bracket can set the float to float in the water tank, so as to sense the change of the liquid level in the water tank through the floating of the float, and then remind the user to add humidifying liquid in time. When the humidifier host is connected to the water tank, the electric switch at the bottom of the shell can abut against the float to make the electric switch conductive, thereby energizing the motor.

[0041] In addition to the technical problems solved by the embodiments of the present application described above, the technical features that constitute the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions, other technical problems that can be solved by the humidification device provided by the present application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific implementation methods.

[0064] An evaporative humidifier usually includes a main unit and a water tank. The main unit includes a housing and a fan. The fan is arranged inside the housing. A filter is arranged inside the water tank. The filter is used to absorb moisture. The fan guides the airflow through the filter and blows it out, so that the airflow carries water vapor and is blown out of the humidifier to achieve the purpose of humidifying the air. After the fan has been running for a period of time, a lot of dust will be absorbed on the blades of the fan. After the dust absorbs the wet mist, it is easy to breed a large number of bacteria. If it is not cleaned in time, it will affect the normal operation of the fan and the cleanliness of the humidifier. However, the fans in the related art are all installed in the housing in an undetachable manner, which makes it inconvenient to clean the blades.

[0065] In view of the above problems, an embodiment of the present application provides a humidifying device, which, by setting a first limiting portion on the rotor sleeve, limits the circumferential relative rotation of the impeller and the motor after the impeller sleeve is set on the rotor sleeve, and by setting a limiting member and a limiting shaft, the axial relative movement of the impeller and the motor can be limited through the cooperation of the two. When disassembly is required, it is only necessary to remove the limiting member from the limiting shaft, and then the impeller can be easily removed from the rotor sleeve, thereby facilitating the cleaning of the impeller.

[0066] The following is combined with Figure 1 To Attachment Figure 8 The technical solution of the humidification device provided in the embodiment of the present application is described in detail.

[0067] Reference Figures 1 to 7 As shown, the humidification device provided in the present application includes a humidification host 100 and a water tank assembly 200, the water tank assembly 200 includes a water tank 210, the humidification host 100 is connected to the water tank 210, and the humidification host 100 includes a shell 110 and a fan assembly 120, the shell 110 has an air cavity 111 connected to the water tank 210, the air cavity 111 has an air outlet 112, and the fan assembly 120 is located on the side of the air cavity 111 facing the air outlet 112.

[0068] The fan assembly 120 includes a motor 121, an impeller 122 and a limiting unit 123, the limiting unit 123 includes a limiting piece 1231 and a limiting shaft 1232, the motor 121 includes a stator 1211 and a rotor sleeve 1212, the stator 1211 is fixed to the air cavity 111, the rotor sleeve 1212 is covered on the outside of the stator 1211, the circumferential side wall of the rotor sleeve 1212 is provided with a first limiting portion 1212a, the impeller 122 is sleeved on the outside of the circumferential side wall of the rotor sleeve 1212, and the first limiting portion 1212a is constructed to fix the impeller 122 in the circumferential direction of the rotor sleeve 1212, the limiting shaft 1232 is installed on the rotor sleeve 1212 along the rotation axis of the rotor sleeve 1212, the limiting piece 1231 and the limiting shaft 1232 are fastened together, and the limiting piece 1231 stops on the side of the impeller 122 facing the air outlet 112.

[0069] In the present application, the water tank 210 is used to store the humidification liquid, the shell 110 is used to form the wind chamber 111 to install the fan assembly 120, and the motor 121 is used to provide power to the impeller 122 to drive the impeller 122 to rotate. When the impeller 122 rotates, it can drive the air to circulate so that the air carries the humidification liquid and is blown out, thereby increasing the air humidity of the surrounding environment.

[0070] Since the air cavity 111 and the water tank 210 are both connected to the external environment, the air in the external environment enters the water tank 210 driven by the impeller 122, then flows into the air cavity 111, and then flows out of the air cavity 111 through the air outlet 112. The air contains dust or impurities. After the impeller 122 has been working for a period of time, a lot of dust will be absorbed by the impeller 122. In order to facilitate the cleaning of the impeller 122, the impeller 122 needs to be removed from the air cavity 111, and at the same time, it needs to be easy to install the impeller 122 into the air cavity 111.

[0071] Therefore, in the above-mentioned arrangement, the impeller 122 is sleeved on the rotor sleeve 1212, and the rotor sleeve 1212 is connected to the impeller 122 through the first limiting portion 1212a to limit the circumferential position of the impeller 122 on the rotor sleeve 1212. In this way, when the fan assembly 120 is working, the stator 1211 generates an electromagnetic field after being energized, and the electromagnetic force drives the rotor sleeve 1212 to rotate relative to the stator 1211, thereby causing the rotor sleeve 1212 to drive the impeller 122 to rotate synchronously, and no relative rotation occurs between the impeller 122 and the rotor sleeve 1212.

[0072] At the same time, in order to prevent the impeller 122 from separating from the rotor sleeve 1212 during rotation, the axial position of the impeller 122 needs to be limited. Therefore, a limit shaft 1232 and a limit member 1231 are provided on the side of the impeller 122 facing the air outlet 112. The limit shaft 1232 is connected to the rotor sleeve 1212 and rotates synchronously with the rotor sleeve 1212. The limit member 1231 is fastened to the limit shaft 1232 and stops on the side of the impeller 122 facing the air outlet 112. In this way, the limit member 1231 cooperates with the limit shaft 1232 to limit the movement of the impeller 122 relative to the rotor sleeve 1212 in the axial direction of the rotor sleeve 1212, so that the impeller 122 is effectively limited in both the circumferential direction and the axial direction of the rotor sleeve 1212.

[0073] When disassembly is required, it is only necessary to remove the limiting member 1231 from the limiting shaft 1232, and then pull out the impeller 122 along the axial direction of the rotor sleeve 1212 to disconnect the impeller 122 from the rotor sleeve 1212 and the limiting shaft 1232. The impeller 122 can be easily removed and moved out of the air chamber 111 to facilitate cleaning of the impeller 122.

[0074] The stopper 1231 may include a nut, and the stopper 1231 and the stopper shaft 1232 may be fastened and connected by a threaded connection, so that the stopper 1231 stops at the side of the impeller 122 facing the air outlet 112. When the impeller 122 needs to be removed, the stopper 1231 can be disconnected from the stopper shaft 1232 by screwing the nut. Alternatively, the stopper 1231 may include a pin, and the pin is inserted into the stopper shaft 1232 along the radial direction of the stopper shaft 1232, so that the stopper 1231 stops at the side of the impeller 122 facing the air outlet 112. When the impeller 122 needs to be removed, the pin can be pulled out to disconnect the stopper 1231 from the stopper shaft 1232. Such a configuration not only makes the structure of the stopper unit 123 and the rotor sleeve 1212 simpler, which is convenient for processing, but also facilitates the installation and removal of the impeller 122, so as to facilitate the cleaning of the impeller 122.

[0075] The humidifying device of the embodiment of the present application comprises a humidifying host 100 and a water tank assembly 200, wherein the water tank assembly 200 comprises a water tank 210, the humidifying host 100 comprises a shell 110 and a fan assembly 120, the shell 110 comprises an air cavity 111 and an air outlet 112, the fan assembly 120 comprises a motor 121, an impeller 122 and a limiting unit 123, the limiting unit 123 comprises a limiting member 1231 and a limiting shaft 1232, the motor 121 comprises a stator 1211 and a rotor sleeve 1212, and the rotor sleeve 1212 comprises a first limiting portion 1212a. A water tank 210 is provided for containing humidification liquid, an air outlet cavity 111 is provided for installing a fan assembly 120, an air outlet 112 is provided for allowing wet mist to flow out, a stator 1211 is provided for forming an electromagnetic field to drive the stator 1211 sleeve to rotate, a rotor sleeve 1212 is provided to drive the impeller 122 to rotate synchronously, an impeller 122 is provided for driving air flow so that the air carries the humidification liquid out, and a first limiting portion 1212a is provided for limiting the circumferential position of the impeller 122 on the rotor sleeve 1212 to prevent the impeller 122 from rotating relative to the rotor sleeve 1212. At the same time, the impeller 122 and the rotor sleeve 1212 can be made detachable. The limiting shaft 1232 and the limiting member 1231 are provided to limit the axial position of the impeller 122 on the rotor sleeve 1212 to prevent the impeller 122 from detaching from the rotor sleeve 1212 when rotating. At the same time, the limiting member 1231 and the limiting shaft 1232 can be made detachable. With such a configuration, when it is necessary to disassemble the impeller 122, the limiting member 1231 can be conveniently removed from the limiting shaft 1232, and the impeller 122 can be removed from the rotor sleeve 1212, so as to facilitate the disassembly and installation of the impeller 122 and thereby facilitate the cleaning of the impeller 122.

[0076] Reference Figure 5 , Figure 6 and Figure 7 As shown, in a possible implementation, the rotor sleeve 1212 has a first axial hole 1212b on the side facing the air outlet 112, the first axial hole 1212b is located on the rotation axis of the rotor sleeve 1212, the limiting shaft 1232 is installed in the first axial hole 1212b, and the limiting shaft 1232 and the rotor sleeve 1212 are relatively fixed in the axial direction of the rotor sleeve 1212.

[0077] In this way, the limiting shaft 1232 can be installed to the rotor sleeve 1212 through the first shaft hole 1212b, and then the impeller 122 is sleeved on the rotor sleeve 1212 after passing through the limiting shaft 1232, so that the displacement of the impeller 122 in the axial direction of the rotor sleeve 1212 can be limited by the limiting member 1231. The limiting shaft 1232 will not move relative to the rotor sleeve 1212 in the axial direction of the rotor sleeve 1212, but the limiting shaft 1232 can rotate relative to the rotor sleeve 1212 in the circumferential direction of the rotor sleeve 1212, and the limiting shaft 1232 can also be fixed relative to the rotor sleeve 1212 in the circumferential direction of the rotor sleeve 1212.

[0078] In a specific implementation, the limiting shaft 1232 is engaged with the first shaft hole 1212b along the axial direction of the rotor sleeve 1212. Alternatively, the limiting shaft 1232 and the hole wall of the first shaft hole 1212b are interference fit.

[0079] Such an arrangement can make the limiting shaft 1232 and the rotor sleeve 1212 relatively fixed in the axial direction of the rotor sleeve 1212 , or make the limiting shaft 1232 and the rotor sleeve 1212 relatively fixed in both the axial direction and the circumferential direction of the rotor sleeve 1212 .

[0080] To facilitate the connection between the limiting member 1231 and the limiting shaft 1232 , in a possible implementation, the limiting shaft 1232 extends toward the air outlet 112 to extend out of the end surface of the rotor sleeve 1212 facing the air outlet 112 .

[0081] In this way, the limiting shaft 1232 can extend out of the first shaft hole 1212b, so that the limiting member 1231 is fastened to the end of the limiting shaft 1232 away from the rotor sleeve 1212, and then the limiting member 1231 is stopped on the side of the impeller 122 facing the air outlet 112 to prevent the impeller 122 from moving axially relative to the rotor sleeve 1212 along the rotor sleeve 1212.

[0082] Reference Figure 4 As shown, in some embodiments, a mounting seat 113 is provided in the air cavity 111, and the mounting seat 113 is configured to support the motor 121. In this way, the stator 1211 of the motor 121 can be fixed relative to the housing 110, and the rotor sleeve 1212 can rotate relative to the stator 1211, thereby driving the impeller 122 to rotate synchronously.

[0083] Reference Figure 5 and Figure 7 As shown, in a specific implementation, the limiting member 1231 includes a hand-held portion 1231a and a threaded connection portion 1231b that are connected to each other, the threaded connection portion 1231b has an internal thread, and the end of the limiting shaft 1232 away from the rotor sleeve 1212 has an external thread matching the internal thread, so that the threaded connection portion 1231b is threadedly connected to the limiting shaft 1232.

[0084] In this way, when it is necessary to disassemble the impeller 122, the user screws the hand-held portion 1231a, thereby screwing the threaded connection portion 1231b out of the limit shaft 1232, thereby disconnecting the limit member 1231 from the limit shaft 1232, thereby facilitating the removal of the impeller 122 from the rotor sleeve 1212, so as to facilitate the cleaning of the impeller 122. After cleaning, the impeller 122 can be sleeved on the rotor sleeve 1212, and then the hand-held portion 1231a is screwed to screw the threaded connection portion 1231b into the limit shaft 1232, so that the limit member 1231 and the limit shaft 1232 are tightly connected. In this way, by threading the limit member 1231 and the limit shaft 1232, it is beneficial to improve the installation efficiency and disassembly efficiency of the impeller 122, and improve the connection reliability between the limit member 1231 and the limit shaft 1232.

[0085] Reference Figure 5 As shown, in a specific implementation, the impeller 122 includes a mounting tube 1221 and blades 1222 connected to the outer peripheral wall of the mounting tube 1221. The end of the mounting tube 1221 away from the air outlet 112 has an opening so that it can be sleeved on the outer side of the rotor sleeve 1212 through the opening.

[0086] In this way, the rotor sleeve 1212 can drive the installation tube 1221 to rotate, and then drive the blades 1222 to rotate synchronously, thereby driving the air flow. When the impeller 122 needs to be installed and removed, it is only necessary to connect the rotor sleeve 1212 through the opening along the axial direction of the rotor sleeve 1212, and pull the impeller 122 out of the rotor sleeve 1212 along the axial direction of the rotor sleeve 1212 through the opening. The installation and disassembly of the impeller 122 is relatively convenient.

[0087] Reference Figure 5 and Figure 6 As shown, in a possible implementation, the end of the mounting cylinder 1221 opposite to the opening has an end face portion, the end face portion has a first mounting hole 1223 coaxially arranged with the center of the rotating shaft 1213 of the rotor sleeve 1212, and the limiting shaft 1232 is sequentially passed through the first shaft hole 1212b and the first mounting hole 1223.

[0088] In this way, when the limit member 1231 is fastened to the limit shaft 1232 and stops on the side of the impeller 122 facing the air outlet 112, the end surface portion can abut against the rotor sleeve 1212, and then the limit member 1231 abuts against the end surface portion, which can effectively limit the impeller 122 from moving relative to the rotor sleeve 1212 along the axial direction of the rotor sleeve 1212.

[0089] In order to facilitate the removal of the impeller 122 and make the limiting shaft 1232 and the impeller 122 rotate synchronously, in some embodiments, the limiting shaft 1232 is a non-circular shaft, and the shape of the first mounting hole 1223 matches the cross-sectional shape of the limiting shaft 1232 .

[0090] In this way, when the rotor sleeve 1212 rotates, it can drive the impeller 122 and the limiting shaft 1232 to rotate synchronously to avoid relative rotation between the limiting shaft 1232 and the first mounting hole 1223, which would cause greater wear on the limiting shaft 1232 or the first mounting hole 1223. When the impeller 122 needs to be disassembled, the first mounting hole 1223 can also be easily separated from the limiting shaft 1232.

[0091] Exemplarily, the cross-sectional shape of the limiting shaft 1232 may be D-shaped, and the cross-sectional shape of the first mounting hole 1223 may also be D-shaped.

[0092] In one possible implementation, in the humidification device provided in the present application, the inner side wall of the mounting cylinder 1221 has a second limiting portion that matches the first limiting portion 1212a, and the second limiting portion and the first limiting portion 1212a are mutually engaged in the circumferential direction of the rotor sleeve 1212 to limit the relative movement of the mounting cylinder 1221 and the rotor sleeve 1212 in the circumferential direction.

[0093] In this way, by the mutual engagement of the first limiting portion 1212a and the second limiting portion, the circumferential position of the mounting cylinder 1221 on the rotor sleeve 1212 can be limited to prevent the impeller 122 and the rotor sleeve 1212 from rotating relative to each other, thereby allowing the rotor sleeve 1212 to drive the impeller 122 to rotate synchronously.

[0094] In some embodiments, one of the first limiting portion 1212a and the second limiting portion is a convex rib extending axially along the rotor sleeve 1212, and the other is a sliding groove matching the shape of the convex rib.

[0095] Exemplarily, the first limiting portion 1212a is a convex rib protruding from the circumferential outer wall of the rotor sleeve 1212, and the second limiting portion is a sliding groove recessed in the circumferential inner wall of the mounting cylinder 1221. In this way, the mounting cylinder 1221 can be effectively restricted from rotating relative to the rotor sleeve 1212 through the engagement between the convex rib and the sliding groove. When the impeller 122 is removed, the sliding groove can slide relative to the convex rib along the axial direction of the rotor sleeve 1212, thereby conveniently removing the impeller 122 from the rotor sleeve 1212.

[0096] Alternatively, the first limiting portion 1212a is a slide groove recessed in the circumferential outer wall of the rotor sleeve 1212, and the second limiting portion is a convex rib protruding from the circumferential inner wall of the mounting cylinder 1221. In this way, the mounting cylinder 1221 can be effectively restricted from rotating relative to the rotor sleeve 1212 by clamping the convex rib and the slide groove. When the impeller 122 is removed, the convex rib can slide relative to the slide groove along the axial direction of the rotor sleeve 1212, thereby conveniently removing the impeller 122 from the rotor sleeve 1212.

[0097] Reference Figures 4 to 6 As shown, in a possible implementation, the motor 121 also includes a rotating shaft 1213, and the rotor sleeve 1212 has a second axial hole on the side away from the limiting shaft 1232, the first end of the rotating shaft 1213 is connected to the second axial hole, and the second end is rotatably arranged on the stator 1211, and the rotating shaft 1213, the stator 1211 and the rotor sleeve 1212 are relatively fixed in the axial direction of the rotor sleeve 1212.

[0098] That is to say, the rotating shaft 1213 and the rotor sleeve 1212 can only rotate relative to the stator 1211 in the circumferential direction of the rotor sleeve 1212, and the rotating shaft 1213 and the rotor sleeve 1212 cannot move relative to the rotor sleeve 1212 in the axial direction of the rotor sleeve 1212. In this way, the stator 1211 generates an electromagnetic field after being energized, which can drive the rotating shaft 1213 to rotate relative to the stator 1211, and then drive the rotor sleeve 1212 to rotate relative to the stator 1211 through the rotor, so that the torque is output through the rotor sleeve 1212 to drive the impeller 122 to rotate.

[0099] Reference Figure 4 As shown, in a specific implementation, the stator 1211 is sleeved on the mounting seat 113 , the mounting seat 113 has a second mounting hole, and the second end of the rotating shaft 1213 is rotatably connected to the second mounting hole through a bearing member 1214 .

[0100] In this way, the stator 1211 can be fixedly installed in the wind chamber 111, and the second end of the rotating shaft 1213 can be rotatably set on the stator 1211, so that the rotating shaft 1213, the stator 1211 and the rotor sleeve 1212 are relatively fixed in the axial direction of the rotor sleeve 1212, and the rotating shaft 1213 and the rotor sleeve 1212 can rotate relative to the stator 1211.

[0101] Reference Figure 8 As shown, in a possible implementation, the humidification device provided in the present application, the humidification host 100 also includes an air outlet net 130, the air outlet net 130 is covered on the air outlet 112, and the air outlet net 130 is detachably connected to the shell 110.

[0102] It can be understood that the air outlet net 130 is used to be connected to the shell 110 to cover the air outlet 112 of the shell 110. The air outlet net 130 is also connected to the opposite sides of the ventilation cavity 111 to provide air circulation. This allows air to circulate while preventing other foreign objects from entering the air cavity 111 to avoid affecting the rotation of the impeller 122. At the same time, by opening the air outlet net 130, the fan assembly 120 can be exposed to facilitate the removal of the impeller 122.

[0103] Reference Figure 8 As shown, in order to facilitate the opening and closing of the air outlet net 130, in a possible implementation, the humidifier host 100 may also include a magnetic attraction component 140, the magnetic attraction component 140 includes a first magnetic component 141 and a second magnetic component 142, the first magnetic component 141 is arranged on the air outlet net 130, and the second magnetic component 142 is arranged on the shell 110, so that the air outlet net 130 is magnetically connected to the shell 110.

[0104] In this way, when no external force is applied, the first magnetic component 141 and the second magnetic component 142 are magnetically attracted to each other, so that the air outlet net 130 is reliably covered on the air outlet 112. When the air outlet net 130 needs to be opened, only a small force is required to disengage the first magnetic component 141 and the second magnetic component 142 from the magnetic connection, thereby allowing the air outlet net 130 to open the air outlet 112, so as to facilitate the removal of the impeller 122 located in the air cavity 111.

[0105] Reference Figure 4 and Figure 5 As shown, in order to automatically cut off the power to the fan assembly 120 when the humidifier host 100 is removed from the water tank 210, in a possible implementation, the humidifier host 100 may also include an electric switch 160, the motor 121 is electrically connected to the electric switch 160, the electric switch 160 is connected to the side of the mounting base 113 away from the air outlet 112, and the electric switch 160 is constructed to cut off the power to the motor 121 when the housing 110 is separated from the water tank 210.

[0106] In this way, before the impeller 122 needs to be removed for cleaning, the humidifier host 100 can be disconnected from the water tank 210. At this time, the electrical switch 160 can automatically cut off the power supply to the motor 121, and the impeller 122 stops rotating, so that it is safer for the user to remove the impeller 122 later.

[0107] Reference Figure 2As shown, in some embodiments, the water tank assembly 200 further includes a water absorbing member 220, a float 230 and a float bracket 240. The side wall of the water tank 210 has an air inlet hole. The water absorbing member 220 is disposed in the water tank 210 and is configured to absorb the humidification liquid in the water tank 210. The float bracket 240 is located in the water absorbing member 220 and is connected to the inner bottom wall of the water tank 210. The float bracket 240 has a floating cavity. One end of the float 230 facing away from the humidification host 100 is inserted into the floating cavity, and the other end extends toward the humidification host 100.

[0108] In this way, the water absorbent 220 absorbs the humidifying liquid in the water tank 210, and the surface of the water absorbent 220 can form a larger evaporation surface, and under the action of the fan assembly 120, the air is driven to circulate, so that the air carries the humidifying liquid on the evaporation surface and blows out, thereby forming water mist, thereby increasing the air humidity of the surrounding environment. The float bracket 240 can float the float 230 in the water tank 210, so as to sense the change of the liquid level in the water tank 210 through the floating of the float 230, and then remind the user to add humidifying liquid in time.

[0109] When the liquid level in the water tank 210 is higher than or equal to the preset liquid level, the end of the float 230 facing the humidification host 100 abuts against the electric switch 160 to trigger the electric switch 160 and thereby energize the motor 121 .

[0110] That is to say, when the humidifier host 100 is connected to the water tank 210, the electric switch 160 located at the bottom of the shell 110 can abut against the float 230 to make the electric switch 160 conductive, thereby energizing the motor 121. As the working progress of the humidification device progresses, the humidification liquid in the water tank 210 will gradually decrease, the liquid level of the humidification liquid will decrease, the float 230 will drop, and the float 230 will be disengaged from the electric switch 160, thereby causing the electric switch 160 to cut off the power supply to the motor 121, and the humidification device stops working. Through the above-mentioned setting, when the humidification liquid in the water tank 210 is less, the power supply to the motor 121 can be cut off, thereby preventing the impeller 122 from idling.

[0111] It should be noted that, for ease of processing and assembly, the shell 110 may include an inner shell 114 and an outer shell 115, the inner shell 114 is connected to the inside of the outer shell 115, the inner wall of the inner shell 114 forms the wind cavity 111, and the outer wall of the outer shell 115 forms the appearance surface.

[0112] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
