Description

Technical Field

[0001] This utility model relates to the field of nursing technology, and in particular to a nursing device. Background Technology

[0002] In existing technology, hair dryers include a hollow duct. The main fluid of the hair dryer is drawn in from the lower end of the handle by a motor inside the handle and then blown out from the annular air outlet at the front end of the nozzle. The high-speed airflow creates negative pressure in the hollow duct, causing a secondary fluid to be generated within it. However, since the high-speed motor already generates sufficient velocity and flow rate, the airflow generated in the hollow duct is less necessary. Furthermore, the inclusion of a hollow duct wastes space in the hair dryer. Utility Model Content

[0029] 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.

[0030] The following is for reference. Figures 1-6 Description of nursing device 100 according to an embodiment of the present utility model.

[0031] Reference Figure 1 and Figure 2 As shown, the nursing device 100 of this utility model embodiment includes: a blower shell 10 and an atomizing device 20. The blower shell 10 has an installation channel 11, an air outlet 12 is formed at the front end of the blower shell 10, and an installation channel 11 extending axially along the rear end of the blower shell 10 is formed at the rear end of the blower shell 10. The atomizing device 20 includes a container 21 and an atomizer 22. The atomizer 22 is disposed inside the blower shell 10, and the container 21 is disposed inside the installation channel 11. The atomizer 22 is in fluid communication with the container 21, thereby atomizing the essential oil in the container 21.

[0032] The air duct shell 10 has an installation channel 11, which can hold other functional components, thereby increasing the multifunctionality of the nursing device 100 and avoiding the single function of the nursing device 100.

[0033] The front end of the air duct housing 10 has an air outlet 12. Since the fan 80 inside the nursing appliance 100 can generate sufficient flow rate and volume, the high-speed airflow can be blown out from the air outlet 12.

[0034] Furthermore, the air outlet 12 is annular, and the annular air outlet 12 is arranged around the axis of the mounting channel 11, and the axis of the mounting channel 11 is perpendicular to the annular air outlet 12.

[0035] Furthermore, the rear end of the air duct shell 10 is provided with an installation channel 11 extending axially along the air duct shell 10. This provides installation space for the container 21 and utilizes the space at the rear end of the air duct shell 10, thereby avoiding increasing the length and height of the nursing device 100. The length of the nursing device 100 is the same as the length of the air duct shell 10, and the height of the nursing device 100 is the same as the height of the handle 50 and the overall height of the air duct shell 10.

[0036] Furthermore, the atomizer 22 is located inside the air tube housing 10, which allows the atomizer 22 to utilize the space inside the air tube housing 10, thus avoiding the atomizer 22 increasing the length and height of the nursing device 100.

[0037] Furthermore, the nebulizer 22 is fixedly connected to the air tube shell 10, which can increase the overall structural strength of the nursing device 100, reduce the risk of mechanical fatigue and damage caused by frequent disassembly and assembly, and reduce the entry of foreign objects into the nursing device 100, thereby further improving the safety of the nursing device 100 in use.

[0038] The atomizer 22 is in fluid communication with the container 21. For example, if there is essential oil in the container 21, the atomizer 22 can atomize the essential oil in the container 21 with high density. Moreover, the atomizer 22 can actively provide the power to spray the essential oil forward, which makes it easier for the essential oil in the container 21 to be sprayed out of the air outlet 12, and can also simplify the atomization structure and spray pipe.

[0039] Therefore, the installation channel 11 in the nursing device 100 can hold the container 21 in the nebulizer 20. This not only makes use of the space in the installation channel 11, but also avoids increasing the axial length and radial dimension of the air duct shell of the nursing device 100. It also simplifies the nebulization structure and spray pipeline, forming the shortest fluid path with the least loss.

[0040] According to some embodiments of the present invention, the atomizer 22 is one of an ultrasonic pump, a pressure pump, and a heater.

[0041] When the atomizer 22 is set as an ultrasonic pump, the ultrasonic pump is mainly used for the application of ultrasonic energy. It breaks the liquid (such as essential oil) into tiny droplets through high-frequency vibration, thereby achieving atomization.

[0042] Specifically, the ultrasonic pump includes an ultrasonic transducer, which can convert electrical energy into high-frequency mechanical vibration. With the high-frequency vibration of the transducer, the liquid can be driven to vibrate together. The high-frequency vibration can generate tension waves on the surface of the liquid, thereby breaking the liquid into tiny droplets.

[0043] Moreover, when ultrasound acts on a liquid, tiny bubbles (cavitation bubbles) are formed in the low-pressure area. These bubbles expand rapidly and collapse violently during the high-pressure cycle. When the cavitation bubbles collapse, they generate high-speed microjet streams. These microjet streams can push the surrounding liquid in a specific direction, thereby providing the propulsion for the tiny droplets to be ejected forward.

[0044] Alternatively, an ultrasonic pump can be equipped with a resonant cavity, which can enhance the energy concentration and propagation efficiency of ultrasonic waves. Within the resonant cavity, ultrasonic waves can form a stable standing wave mode, generating periodic high-pressure and low-pressure zones. These pressure waves can propagate in the liquid, thereby providing the propulsion for the forward ejection of tiny droplets.

[0045] When the atomizer 22 is set as a pressure pump, the pressure pump pressurizes the liquid in the container 21 and sprays it out at high speed through a tiny nozzle, which can break the liquid into tiny droplets, thereby achieving atomization and providing the power for the tiny droplets to be sprayed forward.

[0046] When the atomizer 22 is set as a heater, the heater can evaporate the liquid in the container 21 or generate steam, thereby achieving liquid atomization.

[0047] According to some embodiments of this utility model, such as Figure 3 As shown, the atomizer 22 is arranged along the axial direction of the air duct shell 10, and the container 21 is detachably arranged in the installation channel 11.

[0048] The atomizer 22 is arranged along the axial direction of the air duct shell 10, which simplifies the path of the atomized airflow and allows the airflow to be distributed along the axial direction of the air duct shell 10, thereby making the airflow more stable.

[0049] Furthermore, the atomizer 22 is arranged along the axial direction of the air duct shell 10, which can simplify the atomization structure. For example, it can reduce unnecessary bends and turns, thereby reducing manufacturing complexity and cost.

[0050] Furthermore, the container 21 can be detachably installed within the installation channel 11, which facilitates the installation and replacement of the container 21.

[0051] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the end of container 21 furthest from atomizer 22 is flush with the air duct shell 10.

[0052] The container 21 is located at the rear end inside the air duct shell 10. Moreover, the container 21 does not protrude from the outer contour of the air duct shell 10, which ensures that the container 21 is made of fragile glass. In this way, the air duct shell 10 can protect the glass container 21, thereby preventing the care device 100 from damaging the glass container 21 after a drop. It can also meet the safety specifications for drop tests of care devices 100, and make the whole product more aesthetically pleasing.

[0053] Furthermore, the glass container 21 is transparent, making it easy to observe the amount of liquid inside, thus making it easy to know how the liquid inside the container is being used.

[0054] According to some embodiments of the present invention, the nursing device 100 further includes: an elastic locking mechanism disposed in the installation channel 11. The container 21 has a lockable state and an unlocked state that can be switched under external pressure. When the container 21 is in the locked state, the container 21 is locked by the elastic locking mechanism. When the container 21 is in the unlocked state, the container 21 is unlocked by the elastic locking mechanism, thereby allowing the container 21 to move axially along the air duct shell 10.

[0055] The installation channel 11 provides installation space for the elastic locking mechanism. When the container 21 is pressed, the elastic locking mechanism is compressed and deformed by the pressure. The elastic locking mechanism can lock the container 21 inside the air duct shell 10, thereby fixing the container 21 and preventing the container 21 from moving inside the air duct shell 10.

[0056] When it is necessary to disassemble container 21, by pressing container 21, the elastic locking mechanism can be elastically restored under pressure, thereby unlocking container 21 and making it easy to remove container 21 along the axial direction of air duct shell 10.

[0057] For example, the elastic locking mechanism includes a built-in spring. The user only needs to press the container 21 inward, at which point the spring is compressed and locked, so that the container 21 can be installed into the air duct shell 10. After pressing the container 21 again, the spring returns to its original state and pops the container 21 out. This makes it easy for the user to remove the container 21, which makes it easy for the user to clean or add essential oil.

[0058] Of course, according to other embodiments of this utility model, the end of the container 21 furthest from the atomizer 22 protrudes from the rear end face of the blower housing 10 in both the locked and unlocked states, which makes it easier for the user to remove the container in various ways. The degree of protrusion only needs to be sufficient for the user to pick up or pinch it.

[0059] According to some embodiments of this utility model, such as Figure 2 and Figure 5 As shown, the nursing device 100 also includes a jet element 30, which is connected to the atomizer 22 and is located on the side of the atomizer 22 near the air outlet 12.

[0060] The spray element 30 is connected to the atomizer 22, which atomizes the liquid in the container 21 and then sprays it out from the spray element 30. The spray element 30 can precisely control the spray angle and speed of the liquid, thereby ensuring that the droplets are evenly dispersed and improving the quality of atomization.

[0061] Furthermore, the spray element 30 is positioned on the side of the atomizer 22 near the air outlet 12, so that the liquid sprayed by the spray element 30 can be sprayed towards the designated area under the high-speed airflow of the air outlet 12, thereby preventing the liquid sprayed by the spray element 30 from spreading outward.

[0062] According to some embodiments of this utility model, such as Figure 4 As shown, the nursing device 100 also includes a sensor 40, which is disposed at the front end of the air duct housing 10 and at the top of the air outlet 12.

[0063] Specifically, since the space of the mounting channel 11 of the blower housing 10 is occupied by the atomizing device 20, the sensor 40 is positioned at the top of the air outlet 12. The sensor 40 can be a TOF (Time-of-Flight) sensor, which can detect the distance from the air outlet 12 to the hair. A time-of-flight sensor is a sensor 40 that calculates distance by measuring the time difference between the emission and reception of a light pulse. By applying a TOF sensor to the care device 100, accurate detection of the distance between the hair and the care device 100 can be achieved, thereby optimizing parameters such as the power of the atomizer, the motor, and the heater.

[0064] If the distance sensor 40 detects that the distance between the nursing device and the object being blown is less than threshold a, then the power of the nebulizer is reduced; if the distance sensor detects that the distance between the nursing device and the object being blown is greater than or equal to threshold a and less than threshold b, then the power of the nebulizer is increased; if the distance sensor detects that the distance between the nursing device and the object being blown is greater than or equal to threshold b, then the nebulizer is turned off; where b>a.

[0065] In the embodiments of this utility model, preferably, a is 10cm and b is 30cm. This sensor can be used to collect the distance between the air outlet of the hair care device and the hair, thereby controlling the power of the atomizer. When the hair dryer is close to the hair, for example, when the detected distance is 5cm, the controller in the hair care device controls to reduce the power of the atomizer, so that the atomized liquid is not blown excessively onto the hair. When the hair care device is far from the hair, for example, when the detected distance is 20cm, the power of the atomizer is increased, so that enough atomized liquid is blown onto the hair. When the sensor detects a distance exceeding the normal operating range, the atomizer is turned off to reduce the ineffective consumption of the atomized liquid. Simultaneously, since the air outlet is far from the object being blown, for example, at 40cm, the blowing area is too large. If the power of the atomizer is further increased at this time, it may cause the atomized liquid to be blown onto non-target objects, such as the face or neck skin, clothing, etc., resulting in a reduced user experience or aversion.

[0066] In some other embodiments of this invention, the sensor is a temperature sensor that can detect the temperature of the air outlet and feed back the temperature change of the air outlet to the controller of the nursing device to control the power of the nebulizer. When the current temperature is detected to be high, the power of the nebulizer is reduced. This can reduce other forms of loss of the atomized liquid due to high temperature, such as evaporation, and also prevent excessive atomized liquid from being blown onto the object, causing an unpleasant experience such as dampness or greasiness.

[0067] In some other embodiments of this invention, when the nursing device is in a high-temperature setting, the controller can also directly control the power of the nebulizer instead of through the aforementioned sensor.

[0068] According to some embodiments of this utility model, such as Figure 5 As shown, the air duct housing 10 has an air duct 90, which at least partially surrounds the mounting channel 11. The nursing device 100 also includes a heating element and a circuit board. The heating element is disposed within the air duct 90, and the circuit board is disposed within the air duct 90. The circuit board surrounds the mounting channel 11, and the heating element and the atomizer 22 are electrically connected to the circuit board.

[0069] The air duct shell 10 has an air duct 90, which is spaced apart from the installation channel 11. The fan 80 (high-speed motor and fan blades) inside the nursing device 100 can generate sufficient flow rate and volume, so that the high-speed airflow can pass through the air duct 90 and be blown out from the air outlet 12.

[0070] Furthermore, the heating element is located inside the air duct 90, so that the heating element can heat the airflow inside the air duct 90, thereby facilitating the blowing of hot air from the air outlet 12.

[0071] Furthermore, the circuit board is housed within the air duct 90, thus providing mounting space for the circuit board. Moreover, both the heating element and the circuit board within the air duct housing 10 are arranged in a ring shape, with the circuit board surrounding the mounting channel 11. This allows for efficient use of the space within the mounting channel 11, resulting in a more compact structure.

[0072] Furthermore, the heating element and atomizer 22 are electrically connected to the circuit board, so that the circuit board can control the heating element and atomizer 22 to turn on and off.

[0073] According to some embodiments of this utility model, such as Figure 3 As shown, the volume of container 21 is greater than 20ml and less than 50ml.

[0074] The volume of container 21 must not be less than 20ml. If the volume of container 21 is less than 20ml, liquid needs to be added to container 21 frequently, increasing the difficulty of use for the user. Therefore, the volume of container 21 is set to be greater than 20ml.

[0075] When the volume of container 21 is set to 30ml, the need for frequent liquid addition can be reduced, the volume of container 21 can be reduced, and the weight of container 21 can be reduced.

[0076] The volume of container 21 cannot exceed 50ml. If the volume of container 21 exceeds 50ml, it will easily result in a large volume of container 21, which will make it inconvenient to install container 21 in the installation channel 11. Therefore, the volume of container 21 is set to be less than 50ml.

[0077] According to some embodiments of the present invention, a lamp assembly is provided in the installation channel 11, and the lamp assembly illuminates the installation channel 11.

[0078] The installation channel 11 provides installation space for the lamp assembly. The lamp assembly not only enhances the lighting atmosphere of the duct housing 10, but also illuminates the installation channel 11, making it easier to observe the condition of each component inside the duct housing 10.

[0079] According to another embodiment of the present invention, such as Figure 6 As shown, container 21 is located at the front end of the blower housing 10, that is, at the end near the air outlet 12. Atomizer 22 (i.e. heater) is in fluid communication with container 21. A small amount of liquid in container 21 is transported to atomizer 22 (for example, by using absorbent cotton to transport essential oil to atomizer 22). After being heated, the essential oil in container 21 can be atomized.

[0080] According to some embodiments of this utility model, such as Figure 5As shown, a flip-up screen 70 is provided at the rear end of the air duct housing 10, and the flip-up screen 70 can rotate relative to the rear end of the air duct housing 10. When the user needs to change the container 21, the user can flip open the flip-up screen 70 and then change the container 21. A screen assembly 60 is provided on the flip-up screen 70, which makes it easy to view the operating mode and parameters of the nursing device 100.

[0081] For example, the pivot point of the flip screen 70 is set at the top of the care device 100, which provides relatively high structural strength and also increases the stability of the connection.

[0082] Alternatively, the screen assembly 60 can be located at the connection between the upper end of the handle 50 and the air duct housing 10. For example, the screen assembly 60 is located at the upper end of the handle 50 and in front of the handle 50, which facilitates user operation and allows for easy viewing of the operating mode and parameters of the nursing device 100.
