[0058] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0059] The following is for reference. Figures 1-15 Description of nursing device 100 according to an embodiment of the present utility model.

[0060] Reference Figures 1-3 As shown, the nursing device 100 of the first aspect of the present invention includes: a handle 10, a blower 20, and a nebulizer 30. One end of the blower 20 has an air outlet 21. The nebulizer 30 includes: a nebulizer component 31 and a nebulizer channel 32. The nebulizer component 31 is disposed at the other end of the blower 20. The nebulizer channel 32 is connected to the nebulizer component 31 and extends from the other end of the blower 20 to one end of the blower 20, so that the mist generated by the nebulizer component 31 can be transported to the vicinity of the air outlet 21 through the nebulizer channel 32.

[0061] The handle 10 of the nursing device 100 contains a motor and a fan, and an air inlet is located at the lower end of the handle. The motor drives the fan to rotate, thereby drawing in air from the air inlet and blowing it out from the front end of the blower. One end of the air duct 20 in the nursing device 100 forms an air outlet 21 for easy airflow. The nebulizer 30 mainly consists of a nebulizing component 31 and a nebulizing channel 32. The nebulizing component 31 is located at the other end of the air duct 20, that is, away from the air outlet 21, thus providing a nursing device 100 that is easy to install, compact in layout, and simple in structure.

[0062] Furthermore, the atomizing component 31 and the blower 20 are both independently designed, which facilitates maintenance and replacement, and also allows users to use the atomizing component 31 in a variety of ways. Moreover, the atomizing component 31 can atomize different types of liquids (including liquid oils), for example, the liquid can be set to liquid essential oils or perfumes.

[0063] Furthermore, the atomizing channel 32 is connected to the atomizing component 31, so that the mist generated by the atomizing component 31 can be sprayed out through the atomizing channel 32. Moreover, the atomizing channel 32 extends from the atomizing component 31 to the air outlet 21, which can provide a path for the mist of the atomizing component 31, and can also transport the mist generated by the atomizing component 31 to the vicinity of the air outlet 21 through the atomizing channel 32.

[0064] Furthermore, the atomizing channel 32 can also adopt a variable cross-section design. For example, the atomizing channel 32 can be set as a trumpet shape, with a smaller cross-section near the air outlet 21. This can increase the pressure of the mist spray, thereby further accelerating the mist spray rate and improving the atomization effect.

[0065] Therefore, the atomizing channel 32 in the nursing device 100 provides a path for the mist generated by the atomizing component 31, allowing the mist generated by the atomizing component 31 to be delivered to the vicinity of the air outlet 21 through the atomizing channel 32. Moreover, the atomizing component 31 is located at the other end of the air duct 20, thus providing a nursing device 100 that is easy to install, has a compact layout, and a simple structure.

[0066] According to a second aspect embodiment of the present invention, a nursing device 100 includes: a handle 10, a blower 20, and a nebulizer 30. One end of the blower 20 has an air outlet 21. The nebulizer 30 is disposed on the blower 20. The nebulizer 30 includes: a nebulizer component 31 and a nebulizer channel 32. The nebulizer component 31 has a mist exhaust port 311. The nebulizer channel 32 has a mist inlet 321 and a mist outlet 322. The mist exhaust port 311 is disposed opposite to the mist inlet 321, and the cross-sectional area of ​​the mist exhaust port 311 is not greater than the cross-sectional area of ​​the mist inlet 321. The mist outlet 322 is disposed spaced apart from the air outlet 21, and the mist outlet 322 is used to deliver mist to the vicinity of the air outlet 21.

[0067] The atomizing component 31 has a mist exhaust port 311 through which the liquid inside the atomizing component 31 is discharged as mist. Since the mist exhaust port 311 is arranged opposite to the mist inlet 321, the mist from the atomizing component 31 can directly enter the atomizing channel 32 through the mist inlet 321.

[0068] Furthermore, the cross-sectional area of ​​the exhaust port 311 is no larger than the cross-sectional area of ​​the inlet port 321. This allows the exhaust port 311 to be accurately aligned with the inlet port 321, and the mist discharged from the exhaust port 311 can pass through the inlet port 321 without any obstruction and enter the atomization channel 32, preventing condensation caused by structural obstructions. Simultaneously, the exhaust port 311 and the inlet port 321 are positioned opposite each other, and the cross-sectional area of ​​the exhaust port 311 is no larger than that of the inlet port 321. The extension direction of the atomization channel 32 is also basically consistent with the discharge direction of the exhaust port 311. This avoids complex flow paths that would reduce the power of the mist discharged from the atomization component 31, allowing the mist to flow more smoothly to the front outlet port 322.

[0069] Furthermore, the spacing between the mist outlet 322 and the air outlet 21 reduces the direct impact of high-speed airflow on the atomized particles. This ensures the stability of the atomized material and prevents it from being dispersed or changed direction by the rapid airflow, thus ensuring a more uniform and lasting atomization effect.

[0070] According to some embodiments of this utility model, such as Figure 5 As shown, the atomizing component 31 is detachably mounted at the other end of the blower 20.

[0071] This facilitates the installation and removal of the atomizing component 31 and the blower 20, and also facilitates the maintenance and replacement of the atomizing component 31, thereby reducing costs.

[0072] According to some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, a first magnetic attractor 22 is provided at the other end of the air duct 20, and a second magnetic attractor 312 is provided on the atomizing component 31. The first magnetic attractor 22 and the second magnetic attractor 312 are magnetically attracted together. For example, the first magnetic attractor 22 can be a magnet, and the second magnetic attractor 312 on the side of the atomizing component 31 near the air duct 20 can be a ring-shaped magnetic ring. The magnetic ring can ensure that the atomizing component 31 is stably attracted to the air duct 20 and maintain sufficient pre-tightening force. It can also prevent air leakage between the atomizing component 31 and the air duct 20, thereby improving the overall airtightness.

[0073] Furthermore, the magnetic connection between the blower 20 and the atomizing component 31 allows for quick connection or separation between the blower 20 and the atomizing component 31, and also avoids wear caused by plugging and unplugging, thereby extending its service life.

[0074] According to some other embodiments of the present invention, the other end of the blower 20 is provided with a first snap-fit ​​part, and the atomizing component 31 is provided with a second snap-fit ​​part. The first snap-fit ​​part and the second snap-fit ​​part are snap-fitted together. For example, the first snap-fit ​​part can be provided as a snap protrusion, and correspondingly, the second snap-fit ​​part can be provided as a snap groove. The snap protrusion can extend into the snap groove for snap-fitting. In this way, it is convenient to install and disassemble the blower 20 and the atomizing component 31.

[0075] According to some embodiments of the present invention, at least one of the other end of the blower 20 and the atomizing component 31 is provided with an adhesive part. That is, the other end of the blower 20 may be provided with an adhesive part, or the atomizing component 31 may be provided with an adhesive part, or both the other end of the blower 20 and the atomizing component 31 may be provided with adhesive parts. In this way, the atomizing component 31 can be bonded to the other end of the blower 20, and the connection between the atomizing component 31 and the blower 20 can be made more stable and firm.

[0076] According to some embodiments of this utility model, such as Figure 10 As shown, at least part of the atomizing channel 32 is integrally formed with the air duct 20. That is to say, the atomizing channel 32 can be completely integrally formed with the air duct 20, or part of the atomizing channel 32 can be integrally formed with the air duct 20. For example, the bottom and sides of the atomizing channel 32 can be integrally formed with the air duct 20. In this way, the space of the air duct 20 can be used reasonably, and the additional atomizing channel 32 can avoid occupying a large space in the air duct 20, thereby making its structure more compact and reducing the number of disassembled parts.

[0077] According to some other embodiments of this utility model, such as Figure 13 As shown, the air duct 20 has a mounting groove extending from one end to the other. The atomizing channel 32 can be detachably installed in the mounting groove, which facilitates the cleaning or replacement of the atomizing channel 32 and also facilitates regular cleaning.

[0078] Furthermore, different types of atomization channels 32 can be selected according to different usage needs, thereby meeting the different needs of users.

[0079] According to specific embodiments of this utility model, such as Figure 1 and Figure 10 As shown, the atomizing channel 32 includes a pipe shell 323 and a pipe cover 324. The pipe shell 323 is integrally formed with the air duct 20. An opening extending along its length is formed on the top of the pipe shell 323. The pipe cover 324 is detachably disposed at the opening.

[0080] Specifically, the atomizing channel 32 is mainly composed of a pipe shell 323 and a pipe cover 324. The pipe shell 323 is integrally formed with the air duct 20. This reduces the manufacturing process of the pipe shell 323 and increases its strength, thereby preventing the pipe shell 323 from deforming under stress and extending its service life.

[0081] Furthermore, the pipe cover 324 is detachably provided at the opening, thus facilitating the cleaning of the pipe housing 323.

[0082] Furthermore, the handle 10 is located below the air blower 20, which makes it easier for the user to hold the device and also helps to balance the overall center of gravity of the nursing device 100, making the nursing device 100 more stable when held and less prone to tilting or shaking.

[0083] The atomizing channel 32 is provided with a transparent area extending along its length. For example, the pipe cover 324 of the atomizing channel 32 can be set as a transparent cover. In this way, the atomizing channel 32 can be visualized, and users can directly observe the mist situation in the atomizing channel 32, thereby improving the user experience.

[0084] According to some embodiments of this utility model, such as Figure 2 As shown, the atomizing channel 32 is located above the air duct 20. The atomizing channel 32 has a mist outlet 322, which is located at one end of the air duct 20 and above the air outlet 21 ("above" can refer to directly above or diagonally above). This allows the atomized particles more time to stabilize and diffuse before being blown out, and also reduces the direct impact of high-speed airflow on the newly formed atomized particles, preventing the atomized particles from being blown away by the high-speed airflow, thus making the atomization effect more uniform.

[0085] According to specific embodiments of this utility model, such as Figure 2 As shown, in the air outlet direction, the mist outlet 322 protrudes from the air outlet 21. This can prevent the airflow from the air outlet 21 from directly impacting the atomized particles of the mist outlet 322, thereby improving the atomization effect of the mist outlet 322.

[0086] Furthermore, the distance by which the mist outlet 322 protrudes is d, and d satisfies the relationship: 1mm ≤ d ≤ 8mm. If the distance between the mist outlet 322 and the air outlet 21 is less than 1mm, the mist outlet 322 is too close to the air outlet 21, causing the atomized particles to be too close to the high-speed airflow. In this case, the atomized particles at the mist outlet 322 will be impacted, causing them to be blown away by the high-speed airflow. If the distance between the mist outlet 322 and the air outlet 21 is greater than 8mm, the atomized particles will not be affected by the high-speed airflow due to the distance, and thus cannot completely merge into the high-speed airflow.

[0087] Therefore, preferably, the distance between the mist outlet 322 protruding from the air outlet 21 can be set to 3mm. In this way, the atomized particles can be prevented from being blown away by the high-speed airflow, and the atomized particles can be gathered into the high-speed airflow at an appropriate distance.

[0088] According to some embodiments of this utility model, such as Figure 9 As shown, the nursing device 100 also includes a circuit board 40, which is disposed inside the air duct 20, and the air duct 20 can provide installation space for the circuit board 40.

[0089] Among them, such as Figure 4 and Figure 5 As shown, the atomizing component 31 is provided with a first terminal 313, and the circuit board 40 is provided with a second terminal 41. The first terminal 313 and the second terminal 41 are plugged into each other. This allows for electrical connection between the atomizing component 31 and the circuit board 40. After power is applied, power can be supplied to the atomizing component 31 through the circuit board 40 inside the air duct 20, enabling some electrical components within the atomizing component 31 to operate. The placement of the first terminal 313 and the second terminal 41 also provides a preliminary positional correspondence. Furthermore, the second terminal 41 can be configured as a port, facilitating the insertion of the first terminal 313 into the port. The cooperation between the first terminal 313 and the second terminal 41 also provides communication functionality, allowing control of the on / off state of the electrical components within the atomizing component 31.

[0090] Alternatively, a wireless transmitter can be installed inside the blower 20, which is connected to the circuit board 40. A wireless receiver can be installed inside the atomizing component 31, and the wireless transmitter and the wireless receiver can be wirelessly connected. In this way, power supply and communication to the atomizing component 31 can be achieved through wireless power supply. This can avoid the use and aging of the wiring, thereby extending its service life and simplifying the structure.

[0091] Furthermore, a first airflow channel 11 is formed inside the handle 10, and a second airflow channel 23 is formed inside the air duct 20. The first airflow channel 11 and the second airflow channel 23 are connected in the middle, so that the airflow of the first airflow channel 11 can enter the second airflow channel 23. The air outlet 21 is located at one end of the second airflow channel 23, which makes it easy for the air blown out of the second airflow channel 23 from the air outlet 21.

[0092] Moreover, the circuit board 40 is located at the other end of the second airflow channel 23, which makes reasonable use of the space of the air duct 20, thereby improving the utilization rate of the air duct 20, and facilitating connection and communication with the atomizing component 31 located at the other end of the air duct 20.

[0093] According to some embodiments of this utility model, such as Figure 4As shown, the atomizing channel 32 has an air supply port 325. The air supply port 325 is located at the connection between the atomizing channel 32 and the atomizing component 31, on the upper surface of the air duct 20. Utilizing the chimney effect, the mist flowing out of the atomizing component 31 is driven by the airflow to enter the atomizing channel 32 and then be sprayed out from the mist outlet 322. In this way, the air supply port 325 can provide the flow power for the mist flowing out of the atomizing component 31.

[0094] According to some embodiments of this utility model, such as Figure 4 As shown, the atomizing channel 32 has a mist inlet 321, which is connected to the atomizing component 31. In this way, the mist atomized by the atomizing component 31 can enter the atomizing channel 32 through the mist inlet 321.

[0095] Furthermore, an air supply channel 24 is formed between the other end of the air duct 20 and the atomizing component 31, connecting the external environment and the air supply port 325. This air supply channel 24 is formed by the rear end cover of the air duct 20 and the atomizing component 31, thereby increasing the space of the air supply channel 24 and improving the air intake volume. Specifically, as... Figure 4 and Figure 5 As shown, a recessed first air supply channel 241 is provided on the rear end cover of the air duct 20, below the mist inlet 321. Correspondingly, a recessed second air supply channel 242 is also provided on the atomizing component 31. When the atomizing component 31 is installed on the air duct 20, the first air supply channel 241 of the air duct 20 and the second air supply channel 242 of the atomizing component 31 together form a complete air supply channel 24. This design conceals the air supply channel 24, not only improving the appearance but also preventing dust, moisture, and other contaminants from entering the atomizing channel 32.

[0096] According to some embodiments of this utility model, such as Figure 3 and Figure 7 As shown, the atomizing component 31 includes a housing 33 and an atomizing element 34. The housing 33 forms a storage cavity 331 and a mist outlet 311. The mist outlet 311 is connected to the atomizing channel 32. The atomizing element 34 is disposed inside the housing 33, thereby atomizing the liquid in the storage cavity 331.

[0097] The storage chamber 331 facilitates the storage of atomized liquid. Since the atomizing element 34 is located inside the housing 33, it can refine the liquid in the storage chamber 331 into small particles, thus facilitating the atomization and release of the liquid in the storage chamber 331.

[0098] According to specific embodiments of this utility model, such as Figure 3As shown, a partition 50 is formed inside the housing 33, which divides the storage cavity 331 into a liquid storage cavity 3311 and a liquid absorption cavity 3312. The liquid storage cavity 3311 and the liquid absorption cavity 3312 are connected. The atomizing assembly 31 also includes a liquid absorption structure 60, which is disposed in the liquid absorption cavity 3312 and is connected to the atomizing element 34, so that the liquid it absorbs can be transported to the atomizing element 34.

[0099] Specifically, the liquid storage chamber 3311 can be used to store liquids, such as liquid essential oils. The liquid absorption structure 60 can draw the liquid in the liquid storage chamber 3311 into the liquid absorption chamber 3312 through capillary action. Since the liquid absorption structure 60 is connected to the atomizing element 34, the liquid it absorbs can be transported to the atomizing element 34.

[0100] According to some embodiments of this utility model, such as Figure 3 As shown, the partition 50 is annular, and the liquid suction chamber 3312 surrounds the outer periphery of the liquid storage chamber 3311. Since the liquid suction chamber 3312 and the liquid storage chamber 3311 are annular, the partition 50 is set as annular, which facilitates the separation of the liquid suction chamber 3312 and the liquid storage chamber 3311.

[0101] Also, such as Figure 14 As shown, the partition 50 is provided with a plurality of openings spaced apart along its circumference. The openings are located between the liquid storage chamber 3311 and the liquid suction chamber 3312. The liquid in the liquid storage chamber 3311 can enter the liquid suction chamber 3312 through the plurality of openings.

[0102] Optionally, such as Figure 14 As shown, the liquid absorption structure 60 includes: liquid absorption cotton 61 and adsorption element 62. The liquid absorption cotton 61 is disposed in the liquid absorption cavity 3312, and the adsorption element 62 is connected to the liquid absorption cotton 61 and the atomizing element 34 respectively.

[0103] The absorbent cotton 61 is arranged in a ring shape. The absorbent cotton 61 is connected to the adsorption element 62 and maintains abutment against the adsorption element 62. The absorbent cotton 61 can adsorb the liquid in the liquid storage chamber 3311 and can transfer the liquid to the atomizing element 34 through the adsorption element 62. Since the atomizing element 34 is connected to the adsorption element 62, the liquid in the adsorption element 62 can be evaporated and atomized.

[0104] According to some embodiments of this utility model, such as Figure 3 and Figure 7 As shown, the atomizing component 31 also includes a sealing plug 70, and the housing 33 is provided with a liquid replenishment port communicating with the liquid storage chamber 3311, with the sealing plug 70 disposed at the liquid replenishment port.

[0105] The absorbent cotton 61 is provided with a clearance opening to provide a clearance channel for the liquid replenishment port, and the sealing plug 70 is detachably installed at the liquid replenishment port, which facilitates the addition of liquid and the sealing of liquid.

[0106] According to some embodiments of this utility model, such as Figure 15 As shown, the atomizing channel 32 includes a first pipe section 80 and a second pipe section 81. The first pipe section 80 is connected to the atomizing component 31, which facilitates the entry of the mist from the atomizing component 31 into the first pipe section 80. The second pipe section 81 is connected to the first pipe section 80 and is located downstream of the first pipe section 80, so that the mist from the first pipe section 80 can be ejected through the second pipe section 81.

[0107] Moreover, in the direction of airflow, the distance from the second pipe section 81 to the central axis of the air duct 20 decreases, which provides a direction for the mist to converge toward the annular air outlet 21, thereby preventing the mist from dispersing.

[0108] According to specific embodiments of this utility model, such as Figure 15 As shown, the first pipe section 80 is constructed as a straight pipe section, and the central axis of the straight pipe section is parallel to the central axis of the air duct 20. In this way, the mist can flow parallel to the central axis of the air duct 20.

[0109] The second pipe section 81 is constructed as an arc-shaped pipe section or an oblique pipe section that is inclined relative to the first pipe section 80. In this way, the mist in the first pipe section 80 can converge towards the central axis of the wind tunnel 20 through the second pipe section 81, thereby facilitating the convergence of mist and high-speed airflow.

[0110] According to specific embodiments of this utility model, such as Figure 15 As shown, the end of the second pipe section 81 that is away from the first pipe section 80 is the mist outlet 322. The mist outlet 322 forms an angle α with the central axis of the air duct 20. α satisfies the relationship: 20°≤α≤60°.

[0111] Specifically, the mist outlet 322 is offset towards the air outlet 21 of the air duct 20, providing the mist with a direction to converge towards the annular air outlet 21. If the angle α between the mist outlet 322 and the central axis of the air duct 20 is less than 20°, the mist outlet 322 will not converge towards the air outlet 21, causing the mist to diffuse. If the angle α between the mist outlet 322 and the central axis of the air duct 20 is greater than 60°, the distance between the mist outlet 322 and the air outlet 21 is relatively short, which can easily lead to a direct impact of high-speed airflow on the newly formed mist, preventing the mist from being dispersed by the high-speed airflow.

[0112] Preferably, the angle α between the mist outlet 322 and the central axis of the air duct 20 can be set to 30°, so that the mist can not only be gathered at the air outlet 21, but also the mist can be free from the influence of the high-speed airflow, and the mist can be completely merged into the high-speed airflow.

[0113] Moreover, multiple arc-shaped air outlets are provided at the annular air outlet 21. The atomized liquid is adsorbed into the arc-shaped air outlets, which can further improve the efficiency of the mist merging in the high-speed airflow and being blown forward.

[0114] According to another embodiment of the present invention, the atomizing channel 32 includes: a first pipe section 80 and a second pipe section 81. The first pipe section 80 is connected to the atomizing component 31. The first pipe section 80 has a mist inlet 321. The cross-sectional area of ​​the first pipe section 80 remains constant or increases in the mist outlet direction. In this way, the mist from the atomizing component 31 enters the first pipe section 80 through the mist inlet 321. When the cross-sectional area of ​​the first pipe section 80 increases, the amount of mist entering can be increased, thereby improving the mist entry efficiency.

[0115] Furthermore, the second pipe section 81 is connected to the first pipe section 80, and the second pipe section 81 is located downstream of the first pipe section 80. The second pipe section 81 has a mist outlet 322. The minimum cross-sectional area of ​​the first pipe section 80 is different from that of the second pipe section 81. When the minimum cross-sectional area of ​​the second pipe section 81 is smaller than that of the first pipe section 80, the mist outlet pressure of the second pipe section 81 can be increased, thereby increasing the mist outlet speed of the second pipe section 81.

[0116] According to some embodiments of the present invention, the first pipe section 80 is constructed as a straight pipe section, and the axial direction of the first pipe section 80 is the same as the entry direction of the mist inlet 321.

[0117] In this way, the mist can be sprayed out parallel to the central axis of the air duct 20, making it easier for the user to control the direction of the sprayed mist.

[0118] According to some embodiments of this utility model, such as Figure 1 and Figure 7 As shown, the nursing device 100 also includes a display 90, which is located in the middle of the other end of the blower 20, wherein the atomizing component 31 is constructed in a ring shape and is arranged around the display 90.

[0119] The display 90 can show the atomization status and wind speed status, which makes it easy for the user to adjust.

[0120] Furthermore, the atomizing component 31 is constructed in a ring shape, which facilitates a tight fit between the atomizing component 31 and the blower 20.
