[0066] This embodiment provides a humidifier, such as Figure 1-Figure 2 As shown, the humidifier includes a lower water tank 200 and a head assembly 100. The lower water tank 200 and the head assembly 100 have similar cylindrical or truncated cone structures. The lower water tank 200 is used to hold humidifying liquids such as water and aromatherapy. The head assembly 100 is mounted on the lower water tank 200. Specifically, the head assembly 100 is mounted on the top of the water tank along the axial direction of the body 1. The head assembly 100 is detachably connected to the lower water tank 200 and acts as a cover plate for selectively blocking the top open end of the lower water tank 200.

[0067] During disassembly, the head assembly 100 can be removed from the lower water tank 200 first to expose the top opening of the lower water tank 200, and then the humidifying liquid can be added into the lower water tank 200 through the top opening. After the humidifying liquid is filled, the head assembly 100 can be covered on the top opening of the lower water tank 200.

[0068] In one embodiment, Figure 2 As shown, the humidifier further includes a mist guide tube 300 and an atomizing head 400. The shape of the mist guide tube 300 can be a cylindrical structure. The head assembly 100 is provided with a mist outlet 20. The mist guide tube 300 is arranged in the lower water tank 200 and is arranged corresponding to the mist outlet 20, that is, along the axial direction of the body 1, the mist guide tube 300 is located directly below the mist outlet 20. The inner wall of the mist guide tube 300 and the outer wall size of the atomizing head 400 are adapted. The atomizing head 400 is arranged in the mist guide tube 300 and can slide relative to the mist guide tube 300. The atomizing head 400 is used to spray water mist toward the mist outlet 20.

[0069] Specifically, the atomizing head 400 can float up and down in the mist guide tube 300, and the mist guide tube 300 provides a guide for the sliding of the atomizing head 400, which is used to limit the movement path of the atomizing head 400. The atomizing head 400 can float and change with the changes in the liquid level in the lower water tank 200 or the mist guide tube 300, so that the atomizing head 400 is always in a suspended state, and the atomizing head 400 can also be called a suspended atomizing head. An atomizing generator is provided in the atomizing head 400, which is used to convert the liquid humidifying liquid into a water mist in the state of atomized particles. The atomizing head 400 then supplies mist in a directional manner to the mist outlet 20, so that the mist outlet 20 finally sprays water mist, which is used to increase the humidity of the air and reduce the occurrence of air-conditioning diseases such as skin tightness, dry mouth and tongue, coughs and colds.

[0070] Specifically, if Figure 2-Figure 3 As shown, the head assembly 100 includes a body 1, which is similar to a cylindrical structure. An electrical cavity is provided in the body 1, and the electrical cavity is used to install electrical components.

[0071] The head assembly 100 also includes a mist outlet tube 2, and the mist outlet 20 is arranged on the mist outlet tube 2. The mist outlet tube 2 is penetrated by the main body 1, that is, the mist outlet tube 2 can extend along the axial direction of the main body 1 and pass through the two end faces of the head assembly 100, forming a channel for conveying water mist, so that the water mist generated by the atomizing head 400 is discharged to the external air through the mist outlet tube 2 and the mist outlet 20.

[0072] Existing humidifiers typically require an additional handle structure to lift the handpiece assembly 100. However, this additional handle structure affects the overall appearance of the humidifier, making it less aesthetically pleasing. Even without the additional handle structure, lifting the handpiece assembly 100 with both hands is inconvenient, affecting the user's experience.

[0073] The head assembly 100 provided in this embodiment is as follows: Figure 2-Figure 3 As shown, along the axial direction of the body 1 and toward the mist outlet 20 , the mist outlet tube 2 protrudes from the body 1 , so that the top surface of the mist outlet tube 2 is correspondingly higher than the top surface of the body 1 .

[0074] In this way, the mist outlet tube 2 is not hidden in the main body 1, but the mist outlet tube 2 extends upward along the axial direction of the main body 1 until it leaks out of the main body 1, so that the mist outlet tube 2 protrudes from the main body 1. The user can use the part of the mist outlet tube 2 protruding from the main body 1 to lift it upward, which is convenient for the user to remove the head assembly 100 from the lower water tank 200. The part of the mist outlet tube 2 that leaks out or protrudes from the main body 1 can serve as a handle, which will not affect the overall appearance of the humidifier, ensure the overall coordination and consistency of the humidifier, and thus improve the aesthetics of the humidifier.

[0075] Among them, such as Figure 2-Figure 3 As shown, the head assembly 100 further includes a holding structure 3 , which is disposed on one side of the body 1 along the axial direction of the body 1 and facing the mist outlet 20 , and is annularly disposed outside the mist outlet cylinder 2 .

[0076] The position of the holding structure 3 corresponds to the portion of the mist outlet tube 2 that is exposed or protrudes from the body 1. By setting the holding structure 3 at the portion of the mist outlet tube 2 that is exposed or protrudes from the body 1, the user can use the holding structure 3 to grab the joint assembly. The user can lift the head assembly 100 with one hand and use the other hand to assist in removing the head assembly 100, making installation and disassembly convenient. At the same time, the holding structure 3 is arranged around the outside of the mist outlet tube 2. The structural shape of the holding structure 3 is adapted to the outer shape of the mist outlet tube 2. In appearance, it is not an obvious exposed handle structure, and the appearance is beautiful and consistent.

[0077] like Figure 2-Figure 3 As shown, the main body 1 includes a head seat 12 and a top cover 11. The shape of the head seat 12 is similar to a cylindrical structure, and the electrical cavity is arranged in the head seat 12. The top cover 11 is detachably connected to the head seat 12, which is convenient for installation and maintenance. The mist outlet tube 2 is passed through the head seat 12 and the top cover 11. The mist outlet tube 2 is arranged in the head seat 12, and the mist outlet tube 2 passes through the top cover 11 and is exposed on the top cover 11. The holding structure 3 is arranged on the side of the top cover 11 away from the head seat 12, and the holding structure 3 and the part of the mist outlet tube 2 exposed from the top cover 11 are correspondingly arranged, which is convenient for the user to grab and lift the holding structure 3 from the top of the top cover 11.

[0078] Among them, along the axial direction of the body 1 , a conical surface is provided on a side of the top cover 11 away from the head seat 12 , and the small end of the conical surface is arranged toward the mist outlet tube 2 .

[0079] In this way, the large mouth end of the conical surface of the top cover 11 faces outward, that is, the top cover 11 adopts a large opening setting, so that there is a relatively large operating space between the top end of the mist outlet tube 2 along the axial direction of the main body 1 and the top cover 11, which is convenient for the user to extend his fingers from the large mouth end to the small mouth end, thereby improving the convenience of operation.

[0080] like Figure 2 and Figure 4 As shown, the mist outlet tube 2 includes a first mist outlet portion 201, which is arranged along the axial direction of the main body 1 and toward the mist outlet 20. The top surface of the first mist outlet portion 201 is correspondingly higher than the top surface of the main body 1, and the mist outlet 20 is arranged on the top surface of the first mist outlet portion 201.

[0081] The mist outlet tube 2 also includes a second mist outlet portion 202, which is disposed within the body 1 and connected to the end of the first mist outlet portion 201 away from the mist outlet 20. Along the axial direction of the body 1, the bottom of the second mist outlet tube 2 corresponds to the mist guide tube 300, and the top of the second mist outlet tube 2 is connected to the first mist outlet tube 2. The water mist generated by the atomizing head 400 enters the first mist outlet portion 201 through the second mist outlet portion 202 and is finally discharged from the mist outlet 20.

[0082] It should be noted that the first mist outlet portion 201 and the second mist outlet portion 202 are integrally formed, reducing the number of parts to be assembled and saving production costs. The first mist outlet portion 201 and the second mist outlet portion 202 both function as transport channels for transporting water mist, with the only difference being that the first mist outlet portion 201 is located outside the body 1, i.e., the first mist outlet portion 201 is the portion of the mist outlet tube 2 exposed to the top cover 11, while the second mist outlet tube 2 is located inside the body 1, i.e., the second mist outlet portion 202 is the portion of the mist outlet tube 2 hidden in the headstock 12.

[0083] The holding structure 3 is sleeved on the outside of the first mist outlet portion 201 .

[0084] The holding structure 3 is wrapped around the outside of the first mist outlet tube 2, which protects the exposed part of the mist outlet tube 2 to a certain extent. At the same time, it can also increase the convenience of holding this exposed part, thereby improving the operability and convenience of the user holding and lifting the head assembly 100.

[0085] Specifically, if Figure 4-Figure 5 As shown, the holding structure 3 includes a connecting sleeve 31, which is arranged on the side of the main body 1 facing the mist outlet 20, and the connecting sleeve 31 is sleeved on the outside of the part of the mist outlet tube 2 protruding from the main body 1. For example, the connecting sleeve 31 is sleeved on the outside of the first mist outlet part 201, and the connecting sleeve 31 plays a role in protecting the first mist outlet tube 2. The connecting sleeve 31 can serve as a protective cover for the first mist outlet tube 2.

[0086] When the user holds or lifts the head assembly 100 , the user's fingers will hold the holding portion 32 . Therefore, the holding structure 3 also includes a holding portion 32 , which is arranged on the outer peripheral wall of the connecting sleeve 31 to facilitate the user's fingers to perform holding operations.

[0087] Among them, along the axial direction of the main body 1, one of the sides where the connecting sleeve 31 and the mist outlet tube 2 are close to each other is provided with a first fixing portion 21, and the other corresponding to the first fixing portion 21 is provided with a first fixing matching portion 311, and the first fixing portion 21 is connected to the first fixing matching portion 311.

[0088] For example, the first fixing portion 21 is provided at the upper end of the mist outlet cylinder 2, and the first fixed fitting portion 311 is a slot provided on the connecting sleeve 31. The upper end of the mist outlet cylinder 2 is inserted into the slot, which is used to position and fix the mist outlet cylinder 2 and the connecting sleeve 31. In addition, after the connecting sleeve 31 and the mist outlet cylinder 2 are installed, they can be welded using an ultrasonic process to further improve the connection stability, enhance the sealing effect, and reduce the risk of corrosion in the electrical cavity.

[0089] Specifically, the holding portion 32 may be an annular step, and the annular step is provided along the circumference of the connecting sleeve 31 .

[0090] Since the annular step has certain ups and downs along the radial direction of the main body 1, the outer peripheral wall of the holding portion 32 is not a completely smooth structure, which increases the friction of the holding portion 32, achieves an anti-slip effect, increases the firmness of the user's grasping of the holding portion 32, and improves the operational reliability of the user using the holding portion 32 to lift the head assembly 100.

[0091] For example, the outer peripheral wall of the connecting sleeve 31 is provided with a protrusion 321, so that an annular step is formed between the protrusion 321 and the outer peripheral wall of the connecting sleeve 31. The annular step is formed in an outward convex manner, and the user's fingers can directly contact the protrusion 321, which is convenient for the user to directly operate.

[0092] For example, a recessed portion 322 is provided on the outer peripheral wall of the connecting sleeve 31, forming an annular step between the recessed portion 322 and the outer peripheral wall of the connecting sleeve 31. The use of an inwardly recessed annular step does not occupy the external space of the connecting sleeve 31, further improving the invisible and aesthetic effects. The user's fingers can directly contact the annular step between the recessed portion 322 and the connecting sleeve 31, making it convenient for the user to directly operate.

[0093] Exemplarily, the connecting sleeve 31 is provided with a protrusion 321 and a recess 322 , and an annular step is formed between adjacent protrusions 321 and recesses 322 .

[0094] During actual processing, the recessed portion 322 can be machined on the outer peripheral wall of the connecting sleeve 31, and the portion of the outer peripheral wall of the connecting sleeve 31 not having the recessed portion 322 becomes the raised portion 321; alternatively, the raised portion 321 can be machined on the outer peripheral wall of the connecting sleeve 31, and the portion of the outer peripheral wall of the connecting sleeve 31 not having the raised portion 321 becomes the recessed portion 322. Alternatively, the lower portion of the connecting sleeve 31 along the axial direction of the body 1 is provided with the raised portions 321 and the recessed portions 322 arranged alternately.

[0095] The annular step is formed in an outward convex and inward concave manner, and the annular step is only partially concave or convex relative to the mist outlet tube 2. It is not an obvious exposed handle structure in appearance, but it is convenient for users to exert force by grabbing the annular step. The head assembly 100 can be lifted up with one hand, and the other hand can be used to assist in removing the head assembly 100. It is easy to install and disassemble, and has a beautiful appearance and good coordination and consistency.

[0096] like Figure 4-Figure 5 As shown, the head assembly 100 further includes an isolation tube 4, which is disposed in the body 1 and sleeved on the outside of the mist outlet tube 2. The isolation tube 4 isolates the mist outlet tube 2 from the electrical cavity, preventing the mist in the mist outlet tube 2 from affecting the electrical components in the electrical cavity, and reducing the risk of short circuit or corrosion in the electrical cavity.

[0097] Illustratively, along the axial direction of the main body 1 , one of the sides where the main body 1 and the isolation cylinder 4 are close to each other is provided with a second fixing portion 41 , and the other corresponding second fixing portion 41 is provided with a second fixing fitting portion 111 , and the second fixing portion 41 is connected to the second fixing fitting portion 111 .

[0098] For example, along the axial direction of the body 1, the second fixing portion 41 is a second protrusion or second fixing groove provided on the top of the isolation tube 4, and the second fixing mating portion 111 is a second protrusion or second fixing groove provided on the bottom of the top cover 11. The second protrusion of the isolation tube 4 is inserted into the second fixing groove of the top cover 11, and the second protrusion of the top cover 11 is inserted into the second fixing groove of the isolation tube 4, achieving positioning and fixing through a concave-convex interlocking method. In addition, after installation, the top cover 11 and the isolation tube 4 can be welded using an ultrasonic process, further improving the connection stability, enhancing the sealing effect, and reducing the risk of corrosion in the electrical cavity.

[0099] If the user can only add water after removing the head assembly 100 from the lower water tank 200, the water adding operation steps are relatively cumbersome, and the head assembly 100 is repeatedly disassembled and assembled, which affects the service life.

[0100] For this reason, Figure 5-Figure 6As shown, since the handle portion 32 is exposed from the top cover 11, the water inlet 323 is provided on the handle portion 32, so that the water inlet 323 is also exposed relative to the top cover 11. Along the axial direction of the body 1, the water outlet 22 is provided at the end of the mist outlet tube 2 away from the mist outlet 20. One end of the water channel 40 is connected to the water inlet 323, and the other end is connected to the water outlet 22.

[0101] After the humidifying liquid is added to the water inlet 323, the humidifying liquid enters the sewer channel 40 between the isolation cylinder 4 and the mist outlet cylinder 2. The sewer channel 40 serves to transport the humidifying liquid, and then the humidifying liquid is discharged into the inner cavity of the sewer tank 200 through the water outlet 22 at the bottom of the mist outlet 20.

[0102] In this manner, the humidifying liquid can be added without removing the handpiece assembly 100 from the lower water tank 200, reducing the need for repeated disassembly and assembly of the handpiece assembly 100 and improving ease of use. Furthermore, the humidifier can have two different refilling methods, allowing users to freely select a refilling method based on actual needs. These two refilling methods serve as backups, allowing the other to be used as a backup should one method malfunction.

[0103] For example, since the recessed portion 322 can be a groove provided on the outer peripheral wall of the connecting sleeve 31, the water inlet 323 can be provided at the lowest height position of the recessed portion 322 along the radial direction of the body 1. That is, the water inlet 323 is provided at the bottom of the groove, and the water inlet 323 is not exposed, achieving a hidden effect and good aesthetics.

[0104] In actual processing, a through hole is formed at the bottom of the groove. The bottom of the groove has two side surfaces along the radial direction of the body 1. The through hole penetrates these two side surfaces to form a water inlet 323. When adding the humidifying liquid, the humidifying liquid is first added to the groove. The groove serves to temporarily hold the humidifying liquid to prevent overflow. The humidifying liquid is then transported to the drain channel 40 through the water inlet 323.

[0105] Specifically, the projection of the water inlet 323 on the reference plane coincides with the projection of the recessed portion 322 on the reference plane; wherein the reference plane is parallel to the axial direction of the body 1 .

[0106] Exemplarily, the size of the water inlet 323 extends and expands to the entire bottom of the groove, so that the groove does not actually have a bottom structure. In other words, a through hole is directly opened in the outer peripheral wall of the connecting sleeve 31 to form the water inlet 323. In this case, the water inlet 323 is recessed relative to the outer peripheral wall of the connecting sleeve 31, forming an inwardly recessed step, which makes it easier for the user to hold and lift the entire head assembly 100. At the same time, this recessed area is fully utilized to realize the function of the water inlet, thus achieving multiple uses and strong functionality.

[0107] It should be noted that the top cover 11 has a tapered surface on the side away from the headstock 12. The inclined tapered surface has a guiding effect, and the tapered surface can be used to guide the filling liquid to the water inlet 323. In this case, when adding humidifying liquid, there is no need to directly align it with the water inlet 323. Since the tapered surface of the top cover 11 has a larger area, the filling range is increased, and the convenience of filling is improved.

[0108] It is understood that there are multiple water inlets 323, which are spaced apart along the circumference of the grip portion 32, so that an annular step is formed between the connecting sleeve 31 and the water inlets 323. In this way, the humidifying liquid can be added to any position along the circumference of the connecting sleeve 31, and because the annular step is a full circle structure, it can achieve a good anti-slip effect when the user's five fingers grasp the connecting sleeve 31.

[0109] In one embodiment, Figure 5-Figure 6 As shown, the water inlet 323 includes a first water inlet portion 3231 and a second water inlet portion 3232 which are connected to each other. The first water inlet portion 3231 is arranged along the axial direction of the main body 1, and the second water inlet portion 3232 is arranged along the radial direction of the main body 1. The first water inlet portion 3231 and the second water inlet portion 3232 are both connected to the sewer channel 40.

[0110] With such an arrangement, when filling the wetting liquid, there is no need to be limited to one filling angle. The process of filling the wetting liquid can be achieved along the axial direction and the radial direction of the main body 1. It has good freedom and flexibility, and the range of filling the wetting liquid is relatively large, which improves the convenience of filling.

[0111] It is understandable that the top cover 11 has a center hole, and the first mist outlet portion 201 of the mist guide tube 300 is inserted into the center hole and is located outside the center hole. When the holding structure 3 has a water inlet 323, the connecting sleeve 31 of the holding structure 3 can be considered as a central connecting platform provided in the center of the top cover 11, and the central connecting platform is sleeved on the outside of the first mist outlet portion 201. The holding portion 32 of the holding structure 3 is essentially a plurality of connecting ribs arranged along the edge of the central connecting platform and spaced circumferentially along the central connecting platform. One end of the connecting rib is connected to the central connecting platform, and the other end extends downward along the axial direction of the body 1, then bends and extends along the radial direction of the body 1, and is connected to the inner wall of the center hole. A water inlet 323 is formed between two adjacent connecting ribs. Specifically, the portion of the two adjacent connecting ribs along the axial direction of the body 1 is the first water inlet 3231, and the portion of the two adjacent connecting ribs along the radial direction of the body 1 is the second water inlet 3232, thereby achieving the effect of filling the humidifying liquid over a larger range. At this time, the connecting rib is the protrusion, and the first water inlet portion 3231 of the water inlet 323 is the recessed portion 322, which not only achieves the effect of hiding the decorative steps, but also serves as a hidden lifting structure. The head assembly 100 can be lifted with one hand, making it convenient for users to disassemble the head assembly 100.

[0112] In one embodiment, Figure 5-Figure 6 As shown, the head assembly 100 also includes a mist outlet cover 5, which is arranged on one side of the mist outlet cylinder 2 along the axial direction of the body 1 and facing the mist outlet 20. The mist outlet cover 5 serves to block the open opening of the mist outlet cylinder 2, preventing impurities in the air from directly entering the mist outlet cylinder 2, thereby improving cleanliness. The mist outlet cover 5 is provided with a mist outlet hole 50, which is connected to the mist outlet 20. The water mist enters the mist outlet hole 50 through the mist outlet 20 and is finally discharged into the external air.

[0113] Among them, along the axial direction of the body 1, one of the sides of the mist outlet cover 5 and the holding structure 3 close to each other is provided with a third fixing portion 51, and the other side corresponding to the third fixing portion 51 is provided with a third fixing matching portion 312, and the third fixing portion 51 is provided on the third fixing matching portion 312 and can rotate relative to it (such as Figure 4 shown).

[0114] For example, the third fixing portion 51 is a positioning protrusion provided on the bottom surface of the mist outlet cover 5, and the third fixing mating portion 312 is a positioning groove provided on the connecting sleeve 31, with the positioning protrusion disposed within the positioning groove. In this manner, the mist outlet cover 5 can be rotatably placed above the top cover 11 and can rotate relative to the top cover 11 to adjust the mist outlet direction of the mist outlet 50. When the positioning groove is annular, the mist outlet direction can be adjusted 360 degrees.
