[0022] In a possible implementation, in the humidification device provided in the present application, the first clamping portion is a wedge-shaped block, and the second clamping portion is a rectangular groove.

[0023] In this way, by clamping the wedge block and the rectangular groove, the first clamping portion can be conveniently and reliably clamped to the second clamping portion, thereby fixing the positioning member to the avoidance opening.

[0030] In a possible implementation, in the humidification device provided in the present application, a side of the water retaining surface close to the motor installation cavity is inclined toward the positioning hole relative to a side of the water retaining surface away from the motor installation cavity.

[0031] In this way, when the liquid hits the water retaining surface, it can flow back along the water retaining surface under the action of gravity, thereby preventing the liquid from continuing to flow to the positioning hole.

[0032] In one possible implementation, the humidification device provided in the present application, the fan assembly also includes a limit member, the limit member is threadedly connected to the end of the output shaft of the drive unit away from the motor mounting cavity, and the limit member is stopped on the side of the impeller away from the motor mounting cavity.

[0033] In this way, the stopper cooperates with the output shaft of the driving unit to limit the movement of the impeller relative to the driving unit along the axial direction of the output shaft thereof, thereby improving the stability of the impeller during rotation.

The embodiments of the present application are described in detail below in conjunction with the drawings.

[0061] A humidifier is a device used to adjust the humidity of the air. In the related technology, the humidifier includes a main unit and a water tank. The main unit includes a casing and a fan. The fan may include a motor and fan blades. The casing has a fan cavity and a motor cavity. The fan blades are arranged in the fan cavity. The motor is arranged in the motor cavity. The drive shaft of the motor extends from the motor cavity to the fan cavity and is connected to the fan blades to drive the fan blades to rotate, thereby driving the air flow, so that the airflow carrying water vapor is blown out of the humidifier to achieve the purpose of humidifying the air.

[0062] However, the motor in the related art is mainly fixed by screws during installation, which makes positioning difficult and the transmission shaft of the motor is prone to deviation, thereby causing the humidifier to run unsteadily.

[0063] In view of this, the humidifier device provided in the embodiment of the present application is provided with a positioning groove on the side of the drive unit facing the wind cavity, so that when the drive unit is installed, the positioning groove is aligned with the first positioning portion to radially position the output shaft of the drive unit, and then the side wall of the drive unit facing the wind cavity is abutted against the end wall of the second positioning portion facing the first positioning portion to axially position the output shaft of the drive unit. In this way, it is convenient for the operator to quickly fix the drive unit to the motor mounting cavity subsequently, and at the same time, the output shaft of the drive unit will not deviate significantly relative to the central axis of the positioning hole, thereby providing the assembly accuracy and efficiency of the drive unit, thereby improving the stability of the drive unit during operation.

[0064] The specific implementation of the humidification device provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0065] Reference Figures 1 to 7 As shown, the humidification device provided in the present application includes a humidification host 100 , and the humidification host 100 includes a shell 110 , a fan assembly 120 and a positioning member 130 , and the shell 110 defines an air outlet cavity 111 and a motor installation cavity 112 .

[0066] The fan assembly 120 includes a drive unit 121 and an impeller 122. The drive unit 121 is arranged in the motor mounting cavity 112. The positioning member 130 includes a positioning hole 131, a first positioning portion 132 and a second positioning portion 133. The positioning hole 131 is connected to the wind cavity 111 and the motor mounting cavity 112. The first positioning portion 132 and the second positioning portion 133 are connected in sequence along the axial direction of the positioning hole 131, and the first positioning portion 132 is located at one end of the second positioning portion 133 facing the motor mounting cavity 112.

[0067] The driving unit 121 has a positioning groove 1211 on the side facing the wind cavity 111, and the first positioning portion 132 is inserted in the positioning groove 1211. The side wall of the driving unit 121 facing the wind cavity 111 abuts against the end wall of the second positioning portion 133 facing the first positioning portion 132, and the output shaft of the driving unit 121 is inserted in the positioning hole 131 to be driven and connected to the impeller 122 located in the wind cavity 111.

[0068] In the present application, the fan assembly 120 is used to drive external air into the humidification device, and blow the air out with the humidification liquid, thereby increasing the air humidity of the surrounding environment. The housing 110 is used to define an air outlet cavity 111 for installing an impeller 122, and defines a motor installation cavity 112 for installing a drive unit 121. The drive unit 121 is used to provide power to the impeller 122. The impeller 122 can drive the air to circulate when rotating. The air cavity 111 has an air outlet 1111, and air can flow out from the air outlet 1111.

[0069] In order to improve the assembly accuracy and efficiency of the drive unit 121, the humidifier host 100 may further include a positioning member 130, the positioning member 130 having a positioning hole 131, and the two ends of the positioning hole 131 are respectively connected to the wind cavity 111 and the motor mounting cavity 112, so that the output shaft of the drive unit 121 located in the motor mounting cavity 112 passes through the positioning hole 131 and enters the wind cavity 111, and then connects with the impeller 122, thereby driving the impeller 122 to rotate.

[0070] Since the output shaft of the driving unit 121 needs to rotate relative to the positioning hole 131, there is a certain gap between the outer wall of the output shaft of the driving unit 121 and the inner wall of the positioning hole 131. In order to prevent the output shaft of the driving unit 121 from deviating from the central axis of the positioning hole 131 during installation, the positioning member 130 also has a first positioning portion 132 and a second positioning portion 133. Correspondingly, the driving unit 121 has a positioning groove 1211 on the side facing the wind cavity 111, and the first positioning portion 132 and the second positioning portion 133 are connected in sequence along the axial direction of the positioning hole 131. That is to say, the positioning hole 131 passes through the opposite ends of the positioning member 130, and the first positioning portion 132 and the second positioning portion 133 are connected in sequence along the axial direction of the positioning hole 131.

[0071] It should be noted that during assembly, the drive unit 121 enters the motor mounting cavity 112 from the side of the motor mounting cavity 112 away from the air outlet 1111, and then the output shaft of the drive unit 121 is inserted into the positioning hole 131, and the drive unit 121 continues to move axially along its output shaft until the first positioning portion 132 is inserted into the positioning groove 1211. At this time, the first positioning portion 132 and the positioning groove 1211 can cooperate to limit the radial movement of the drive unit 121 along its output shaft, thereby preliminarily positioning the installation of the drive unit 121. Then, the drive unit 121 continues to move axially along its output shaft until the drive unit 121 faces the side wall of the air cavity 111 and the second positioning portions face the end wall of the first positioning portion 132. At this time, the drive unit 121 cannot continue to move axially along its output shaft. In this way, through the cooperation between the drive unit 121 and the second positioning portion 133, the axial movement of the drive unit 121 along its output shaft is limited, thereby performing secondary positioning on the installation of the drive unit 121. Finally, the drive unit 121 may be fixed to the cavity wall of the motor installation cavity 112 by means of threaded fasteners, thereby completing the installation process of the drive unit 121 .

[0072] Compared with the prior art method of directly fixing with threaded fasteners, the humidifying device provided in the embodiment of the present application is provided with a positioning member 130, and the positioning member 130 can be first used to cooperate with the driving unit 121 to accurately locate the installation position of the driving unit 121, and then the driving unit 121 can be fixed, so that the output shaft of the driving unit 121 can be coaxial with the central axis of the positioning hole 131, which not only improves the assembly efficiency of the driving unit 121, but also improves the assembly accuracy of the driving unit 121. Therefore, in the subsequent use process, the driving unit 121 will run more smoothly, thereby preventing the humidifying device from shaking.

[0073] The humidifying device provided in the embodiment of the present application includes a humidifying host 100, the humidifying host 100 includes a shell 110, a fan assembly 120 and a positioning member 130, the shell 110 includes an air cavity 111 and a motor mounting cavity 112, the fan assembly 120 includes a driving unit 121 and an impeller 122, the positioning member 130 includes a positioning hole 131, a first positioning portion 132 and a second positioning portion 133, and the driving unit 121 includes a positioning groove 1211. The wind cavity 111 is provided to provide an installation space for the impeller 122, the motor installation cavity 112 is provided to provide an installation space for the drive unit 121, the drive unit 121 is provided to provide power for the impeller 122, the impeller 122 is provided to drive the air flow, and the positioning hole 131 is provided to connect the wind cavity 111 and the motor installation cavity 112, so that the output shaft of the drive unit 121 extends to the wind cavity 111 through the positioning hole 131, and the positioning groove 1211 is provided to cooperate with the first positioning portion 132 to radially position the output shaft of the drive unit 121 when the drive unit 121 is installed, and the second positioning portion 133 is provided to cooperate with the drive unit 121 to axially position the output shaft of the drive unit 121 when the drive unit 121 is installed. In this way, the coaxiality of the output shaft of the drive unit 121 and the central axis of the positioning hole 131 can be improved, thereby improving the installation efficiency and installation accuracy of the drive unit 121, thereby reducing the shaking of the drive unit 121 during operation.

[0074] Specifically, the driving unit 121 may include an interconnected motor 1212 and a mounting member 1213 , wherein the motor 1212 is used to provide power to the impeller 122 , and the mounting member 1213 is used to install the motor 1212 to the motor mounting cavity 112 , and the mounting groove is located on the side of the mounting member 1213 facing the wind cavity 111 .

[0075] In a possible implementation, the bottom wall of the motor installation cavity 112 facing away from the air cavity 111 is flush with the end wall of the second positioning portion 133 facing the first positioning portion 132 .

[0076] In this way, when installing the drive unit 121, the side wall of the drive unit 121 facing the wind cavity 111 can simultaneously abut against the bottom wall of the motor installation cavity 112 facing away from the wind cavity 111 and the end wall of the second positioning portion 133 facing the first positioning portion 132, so as to limit the drive unit 121 from continuing to move toward the wind cavity 111, thereby facilitating the subsequent fixing of the drive unit 121.

[0077] Reference Figure 5 As shown, in some embodiments, the bottom wall of the air cavity 111 facing the motor installation cavity 112 has an escape opening 113 , and the positioning member 130 is inserted into the escape opening 113 .

[0078] That is to say, both ends of the avoidance opening 113 are also connected to the wind cavity 111 and the motor installation cavity 112 respectively. After the positioning member 130 is inserted into the avoidance opening 113, the positioning member 130 can be fixed on the shell 110, so as to facilitate the subsequent installation and positioning of the drive unit 121 through the positioning member 130. The positioning hole 131 of the positioning member 130 is connected to the wind cavity 111 and the motor installation cavity 112, and is then used to insert the output shaft of the drive unit 121.

[0079] Reference Figure 5 and Figure 6 As shown, in a possible implementation, the positioning member 130 also includes a third positioning portion 134, and the first positioning portion 132, the second positioning portion 133 and the third positioning portion 134 are connected in sequence along the axial direction of the positioning hole 131, and the avoidance opening 113 includes a first connecting section and a second connecting section that are connected in sequence, the first connecting section is located at one end of the second connecting section facing the motor mounting cavity 112, and the projection of the second connecting section on the first connecting section is located within the first connecting section.

[0080] The third positioning portion 134 is inserted in the second communication section, the end wall of the third positioning portion 134 facing the second positioning portion 133 abuts against the end wall of the second communication section facing the first communication section, and the second positioning portion 133 is inserted in the first communication section.

[0081] It should be understood that when installing the positioning member 130, the positioning member 130 is inserted into the avoidance port 113 from the avoidance port 113 toward one end of the wind cavity 111. Therefore, in order to install and position the positioning member 130, the positioning member 130 may also have a third positioning portion 134. The avoidance port 113 may include a first connecting section and a second connecting section to form a stepped avoidance port 113. In this way, after the end wall of the third positioning portion 134 toward the second positioning portion 133 abuts against the end wall of the first connecting section, the positioning member 130 cannot continue to move along the axis of the positioning hole 131 toward the direction of the motor mounting cavity 112. Thereafter, the positioning member 130 can be fixed to the avoidance port 113, thereby fixing the positioning member 130 to the housing 110.

[0082] Reference Figure 5 and Figure 6 As shown, in some embodiments, the positioning member 130 further includes a water retaining portion 135 , the water retaining portion 135 is connected to an end of the third positioning portion 134 away from the second positioning portion 133 , and the water retaining portion 135 is inserted in the second connecting section.

[0083] With such arrangement, the water retaining portion 135 can prevent the liquid in the air cavity 111 from entering the motor mounting cavity 112 , thereby preventing the liquid from entering the interior of the driving unit 121 , so as to avoid the liquid from causing a circuit short circuit in the driving unit 121 .

[0084] Reference Figure 5 and Figure 6 As shown, in some embodiments, the positioning member 130 also includes a first clamping portion 136, the first clamping portion 136 is connected to the outer peripheral wall of the third positioning portion 134, the inner side wall of the second connecting section has a second clamping portion 1131, the first clamping portion 136 and the second clamping portion 1131 both extend along the circumference of the third positioning portion 134, and the first clamping portion 136 is connected to the second clamping portion 1131.

[0085] In this way, by cooperating with the first clamping portion 136 and the second clamping portion 1131, the positioning frame can be clamped in the avoidance opening 113, and then the positioning member 130 can be fixedly installed to the bottom wall of the air cavity 111 facing the motor installation cavity 112, so as to facilitate the subsequent positioning of the drive unit 121 through the positioning member 130 when installing the drive unit 121.

[0086] In a possible implementation, there are at least two first clamping portions 136 , and the at least two first clamping portions 136 are spaced apart along the circumference of the third positioning portion 134 , and the second clamping portions 1131 are connected to the first clamping portions 136 in a one-to-one correspondence.

[0087] Compared with the method of only setting one first clamping portion 136 and the second clamping portion 1131, the above-mentioned setting method provides multiple first clamping portions 136 and second clamping portions 1131, which can prevent the positioning member 130 from rotating relative to the avoidance opening 113 during subsequent use, thereby allowing the positioning member 130 to be reliably fixed to the bottom wall of the air cavity 111 facing the motor mounting cavity 112.

[0088] In some embodiments, the first clamping portion 136 is a wedge block, and the second clamping portion 1131 is a rectangular groove. Thus, the first clamping portion 136 can be conveniently and reliably clamped to the second clamping portion 1131 by clamping the wedge block and the rectangular groove, thereby fixing the positioning member 130 to the avoidance opening 113.

[0089] In some embodiments, the positioning member 130 is a rotating body structure, the outer diameter of the first positioning portion 132 is smaller than the outer diameter of the second positioning portion 133 , and the outer diameter of the second positioning portion 133 is smaller than the outer diameter of the third positioning portion 134 .

[0090] In this way, along the axial direction of the positioning hole 131, the outer diameter of the positioning member 130 from the end away from the wind chamber 111 to the end close to the wind chamber 111 has three gradients, so that the positioning member 130 has a plurality of positioning boss structures, so that the end wall of the second positioning portion 133 toward the first positioning portion 132 can cooperate and abut with the side wall of the drive unit 121 toward the wind chamber 111, and the end wall of the third positioning portion 134 toward the second positioning portion 133 can cooperate and abut with the end wall of the second connecting section toward the first connecting section.

[0091] Reference Figure 2and Figure 5 As shown, in a possible implementation, the humidifier host 100 also includes an elastic positioning ring 140, which is sleeved on one end of the second positioning portion 133 away from the first positioning portion 132, and the elastic positioning ring 140 abuts between the inner wall of the avoidance opening 113 and the outer wall of the second positioning portion 133.

[0092] In this way, during the installation process of the drive unit 121, if the output shaft of the drive unit 121 shakes slightly, since an elastic positioning ring 140 is provided between the inner wall of the avoidance opening 113 and the outer wall of the second positioning portion 133, the elastic positioning ring 140 has a small deformation amount, which can make the positioning member 130 move slightly along the radial direction of the positioning hole 131 relative to the avoidance opening 113. In this way, the elastic positioning ring 140 can assist in positioning to prevent a large deviation between the output shaft of the drive unit 121 and the central axis of the positioning hole 131, thereby improving the installation accuracy of the drive unit 121.

[0093] For example, the elastic positioning ring 140 may be a rubber ring or a silicone ring.

[0094] Reference Figure 6 As shown, in some embodiments, the outer peripheral side of the water retaining portion 135 has a water retaining surface 1351, and the water retaining surface 1351 is inclined relative to the axial direction of the positioning hole 131. In this way, when the liquid encounters the water retaining surface 1351, the water retaining surface 1351 can prevent the liquid from entering the motor mounting cavity 112 along the positioning hole 131, and the water retaining surface 1351 can guide the liquid to flow.

[0095] In some embodiments, a side of the water retaining surface 1351 close to the motor installation cavity 112 is inclined toward the positioning hole 131 relative to a side of the water retaining surface 1351 away from the motor installation cavity 112 .

[0096] That is to say, when the positioning member 130 is a rotating body structure, the water retaining surface 1351 is a conical surface, and the large diameter end of the water retaining surface 1351 is connected to the third positioning portion 134, and the small diameter end of the water retaining surface 1351 is set away from the third positioning portion 134. In this way, when the liquid hits the water retaining surface 1351, it can flow back along the water retaining surface 1351 under the action of gravity, thereby preventing the liquid from continuing to flow to the positioning hole 131.

[0097] Reference Figure 2 As shown, in a possible implementation, the fan assembly 120 also includes a limit member 123, which is threadedly connected to one end of the output shaft of the drive unit 121 away from the motor mounting cavity 112, and the limit member 123 stops on the side of the impeller 122 away from the motor mounting cavity 112.

[0098] In this way, the stopper 123 cooperates with the output shaft of the driving unit 121 to limit the movement of the impeller 122 relative to the driving unit 121 along the axial direction of the output shaft thereof, thereby improving the stability of the impeller 122 during rotation.

[0099] Furthermore, when the impeller 122 needs to be disassembled, it is only necessary to remove the stopper 123 from the output shaft of the driving unit 121 , and then pull out the impeller 122 in the axial direction of the output shaft of the driving unit 121 .

[0100] Reference Figure 1 and Figure 8 As shown, in a possible implementation, the humidifying device provided by the present application further includes an electric switch component 150 and a water tank 210 assembly, the water tank assembly 200 includes a water tank 210, the wind chamber 111 is connected to the water tank 210, the electric switch component 150 is connected to the side of the shell 110 facing the water tank 210, the drive unit 121 is electrically connected to the electric switch component 150, and the electric switch component 150 is constructed to cut off power to the drive unit 121 when the shell 110 is separated from the water tank 210.

[0101] It should be noted that the water tank assembly 200 may further include a filter 220, a float 230 and a float bracket 240. The side wall of the water tank 210 has an air inlet hole. The filter 220 is disposed in the water tank 210 and is configured to absorb the humidification liquid in the water tank 210. The surface of the filter 220 may form a large evaporation surface, and the air is driven to circulate through the fan assembly 120, so that the air carries the humidification 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 is located in the filter 220 and 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 away from the humidification host 100 is inserted into the floating cavity, and the other end extends toward the humidification host 100. The float 230 is floatingly arranged in the water tank 210 to sense the change of the liquid level in the water tank 210 through the floating of the float 230, thereby reminding the user to add humidifying liquid in time. In this way, 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 150 to trigger the electric switch 150, thereby energizing the drive unit 121. When the liquid level in the water tank 210 is lower than the preset liquid level, the end of the float 230 facing the humidification host 100 is disengaged from the abutment with the electric switch 150, thereby disconnecting the drive unit 121, thereby ensuring the safety of the humidification device.

[0102] Reference Figure 1 and Fig. 9 As shown, in addition, the humidifying device may further include an air outlet net 300 , which can be opened and closed to cover the air outlet 1111 to prevent foreign matter from entering the air cavity 111 .
