Detailed Implementation

[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] Combination Figure 1 as well as Figure 2 As shown, this application provides a spraying device 100, which includes a support component 110, a ventilation component 120, and an atomizing component 130.

[0040] Specifically, such as Figure 2 as well as Figure 3 As shown, the support assembly 110 has a mounting cavity 111 and a mixing outlet 112. The mounting cavity 111 and the mixing outlet 112 are connected. The ventilation assembly 120 is mounted in the mounting cavity 111. The ventilation assembly 120 has a first air outlet 121 and a first air inlet 123. The first air outlet 121 and the first air inlet 123 are connected to form an air supply channel 122. The first air outlet 121 is connected to the mixing outlet 112.

[0041] The atomizing assembly 130 is installed in the mounting cavity 111. The atomizing assembly 130 includes a housing assembly 131 and an atomizing element 132. The housing assembly 131 has an atomizing cavity 130a and a second air outlet 130b, and the atomizing element 132 is disposed within the atomizing cavity 130a. The atomizing element 132 is used to atomize the fluid within the atomizing cavity 130a. The atomizing cavity 130a is spaced apart from the air supply channel 122. The atomizing cavity 130a communicates with the second air outlet 130b. The second air outlet 130b communicates with the mixing outlet 112.

[0042] The atomizing chamber 130a can be pre-stored with fluids such as serums, essential oils, or water. Alternatively, it can be connected to external components to allow fluids such as serums, essential oils, or water to flow into the atomizing chamber 130a, where the atomizing element 132 atomizes the fluids.

[0043] Understandably, the atomizing element 132 within the atomizing chamber 130a atomizes the fluid, allowing essential oils, serums, and other fluids to be atomized into a mist that flows out from the second air outlet 130b. The first air inlet 123 of the ventilation assembly 120 can connect with other air inlets, enabling the air supply channel 122 to blow out gas. The gas in the air supply channel 122 and the mist from the atomizing chamber 130a can mix and be discharged through the mixing outlet 112. Due to the airflow, the mist is evenly dispersed in the air, allowing the atomized fluid (such as essential oils, serums, or water) to adhere more evenly to the surface being treated, such as hair, thus enhancing the treatment effect.

[0044] For ease of understanding, combined with Figure 4 as well as Figure 5 As shown, the application scenario of the spray device 100 described above will be described below with reference to one embodiment. This application also provides a hair dryer 10. For example... Figure 6 As shown, the hair dryer 10 includes the spray device 100, the hair dryer body 200, and the control component 300 in the above embodiments.

[0045] like Figure 4 as well as Figure 6As shown, the hair dryer body 200 has a first cavity 210, a second cavity 220, a second air inlet 230, and a third air outlet 240. The second air inlet 230 and the third air outlet 240 are arranged opposite to and connected on both sides of the second cavity 220 to form a working air duct 220a. The first cavity 210 has an opening 211, through which the spray device 100 is detachably connected to the first cavity 210, and the opening 211 is connected to the mixing outlet 112. The control component 300 is used to supply power to the hair dryer body 200. The first air inlet 123 is connected to the working air duct 220a.

[0046] Specifically, when the control component 300 supplies power to the hair dryer body 200, the working air duct 220a has airflow to achieve the blowing function, outputting either cold or hot air, and at this time, the working air duct 220a is in working condition. Correspondingly, when the control component 300 does not supply power to the hair dryer body 200, the working air duct 220a cannot achieve the blowing function.

[0047] Generally, in related technologies, when manufacturers place the container containing essential oils directly at the nozzle of the hair dryer, the evaporation rate of the essential oils is related to the operating temperature of the hair dryer 10. Specifically, when using the cool air function of the hair dryer 10, the essential oils evaporate more slowly; while when using the hot air function, the essential oils evaporate more quickly, resulting in different evaporation rates in different scenarios and unstable care performance of the hair dryer 10. On the other hand, when the user turns on the hot air function of the hair dryer 10, the temperature at the air outlet is very high, which can easily damage the efficacy of the essential oils, leading to poor care performance.

[0048] Understandably, when the control component 300 powers the hair dryer body 200, the working air duct 220a can have a certain air volume, enabling the blowing function. The working air duct 220a blows air through the third air outlet 240. At this time, since the working air duct 220a is connected to the first air inlet 123, it can also be connected to the air supply channel 122, allowing a portion of the air volume to be blown out from the first air outlet 121.

[0049] In one example scenario, when the control component 300 drives the hair dryer body 200 to perform the cold air function, the working air duct 220a is connected to the air supply channel 122, so that the air supply channel 122 can blow out cold air through the first air outlet 121, and the atomizing chamber 130a can blow out mist through the second air outlet 130b, so that the cold air and mist are mixed in the mixing outlet 112 and discharged, thereby achieving both the function of blowing cold air for drying and the function of hair care.

[0050] In another example scenario, when the control component 300 drives the hair dryer body 200 to perform the hot air function, the working air duct 220a can be connected to the air supply duct 122, allowing the air supply duct 122 to blow out hot air through the first air outlet 121, while the atomizing chamber 130a can blow out mist through the second air outlet 130b. This allows the hot air and mist to mix and be discharged in the mixing outlet 112, achieving both hot air drying and hair care functions. Furthermore, the design of the air supply duct 122 helps to extend the transmission path of the hot air, thereby reducing the temperature of the hot air in the air supply duct 122 to a certain extent, preventing the hot air temperature from being too high and affecting the care effect of fluids such as essential oils and serums.

[0051] In some embodiments, see back Figure 3 The atomizing assembly 130 includes a first housing 1311 and a second housing 1312. The first housing 1311 has a first receiving cavity 1311a for holding fluid. The second housing 1312 has an atomizing cavity 130a and a second air outlet 130b. The atomizing cavity 130a and the second air outlet 130b are connected. In this way, fluid can be placed in the first receiving cavity 1311a, avoiding the need for an external component to receive fluid every time fluid is used for treatment, thus improving the ease of use of the spray device 100.

[0052] Furthermore, in some of these embodiments, see back Figure 2 as well as Figure 3 The first housing 1311 is also provided with a liquid inlet 1311b. The liquid inlet 1311b is connected to the first accommodating cavity 1311a.

[0053] In one embodiment, the spraying device 100 further includes a one-way valve disposed at the liquid inlet 1311b. When the external hydraulic pressure is greater than the hydraulic pressure within the first accommodating cavity 1311a, the one-way valve is in the open state, and the first accommodating cavity 1311a is connected to the outside through the liquid inlet 1311b. When the external hydraulic pressure is less than or equal to the hydraulic pressure within the first accommodating cavity 1311a, the one-way valve is in the closed state, and the first accommodating cavity 1311a is not connected to the outside.

[0054] In one usage scenario, when it is necessary to replenish fluid (such as serum, essential oil or water), for example, when the user connects the spray device 100 to an external reservoir or pipe, and the external hydraulic pressure is greater than the hydraulic pressure in the first accommodating cavity 1311a, the one-way valve is pushed by the external pressure and is in the open state, so that fluid can be replenished in the first accommodating cavity 1311a.

[0055] In another application scenario, when no fluid replenishment is required, the pressure applied to the one-way valve from the outside mainly comes from atmospheric pressure. Atmospheric pressure is less than the hydraulic pressure inside the first accommodating chamber 1311a, that is, the external hydraulic pressure is less than or equal to the hydraulic pressure in the first accommodating chamber 1311a. The one-way valve is in the closed state due to internal pressure or its own elasticity, which can prevent the fluid from flowing back when the internal pressure of the spray device 100 is high, and ensure that the fluid can only flow in one direction.

[0056] This effectively prevents fluid overflow, such as fluid backflow into external storage bottles or pipes, avoiding fluid waste and contamination. It also ensures that foreign objects from the outside will not enter the first accommodating cavity 1311a through outside air, ensuring the purity and stability of the fluid inside the spray device 100, and improving the reliability of the device and the user experience.

[0057] It should be noted that the check valve can be, but is not limited to, a check ring, a duckbill check valve, or a spring-loaded online check valve, etc., without too many restrictions here.

[0058] In another embodiment, the spray device 100 further includes a cover assembly that is detachably disposed over the liquid inlet 1311b, such that the cover assembly can switch between being sealed to the liquid inlet 1311b and being spaced apart from the liquid inlet 1311b.

[0059] Specifically, when the cover assembly is sealed to the inlet 1311b, the sealing surface of the cover assembly fits tightly against the sealing surface of the inlet 1311b, forming a sealed environment. At this time, fluid cannot enter the spray device 100 through the inlet 1311b, ensuring the sealing performance of the spray device 100 when not in use. The sealing connection can be achieved through threads, snaps, magnetic attraction, etc., and the specific connection method can be selected according to different production needs.

[0060] When the cap assembly and the liquid inlet 1311b are spaced apart, a certain space exists between them, allowing fluid to enter the spray device 100 through the liquid inlet 1311b. In this case, the spray device 100 can be connected to the liquid inlet 1311b via an external storage bottle or pipe to replenish the fluid. The spaced arrangement between the cap assembly and the liquid inlet 1311b can be achieved through a simple disassembly action, such as rotating the cap assembly.

[0061] Furthermore, in other embodiments, see back Figure 1 as well as Figure 2 The atomizing component 130 is slidably disposed within the mounting cavity 111. When the atomizing component 130 slides relative to the mounting cavity 111, the carrier component 110 can slide and switch between being disposed covering the liquid inlet 1311b and being disposed at an interval from the liquid inlet 1311b.

[0062] That is, when the carrier component 110 covers the liquid inlet 1311b, it can effectively prevent external impurities from entering the first receiving cavity 1311a, which is beneficial to ensuring the fluid effect and hygiene. When the carrier component 110 and the liquid inlet 1311b are spaced apart, the fluid can enter the first receiving cavity 1311a through the liquid inlet 1311b. In this way, by sliding the atomizing component 130 relative to the carrier component 110, the user can easily control the opening and closing of the liquid inlet 1311b, improving the performance of the spray device 100.

[0063] It should be noted that the atomizing component 130 can slide relative to the mounting cavity 111 in various ways, such as by sliding the atomizing component 130 relative to the ventilation component 120 and the mounting cavity 111, or by the ventilation component 120 and the atomizing component 130 sliding synchronously relative to the mounting cavity 111. No further restrictions are imposed here.

[0064] In some embodiments, such as Figure 6 as well as Figure 7 As shown, the ventilation component 120 is disposed within the first accommodating cavity 1311a, and the air supply channel 122 is not connected to the first accommodating cavity 1311a. Thus, by disposing of the ventilation component 120 within the first accommodating cavity 1311a, the integration performance of the ventilation component 120 and the atomizing component 130 is improved, thereby facilitating the miniaturization of the spray device 100.

[0065] Furthermore, in one embodiment, such as Figure 7 As shown, the atomizing assembly 130 also includes a third housing 1313. The third housing 1313 has a second receiving cavity 1313a. The first housing 1311 is inserted into the second receiving cavity 1313a. The first housing 1311 has a plurality of spaced-apart through holes 1311c. The first receiving cavity 1311a and the through holes 1311c communicate with the second receiving cavity 1313a. It can be understood that in this embodiment, the atomizing assembly 130 has two flow paths to the atomizing cavity 130a. One flow path is for fluid to flow directly from the first receiving cavity 1311a to the atomizing cavity 130a; the other flow path is for fluid to flow from the second receiving cavity 1313a, through the through holes 1311c, the first receiving cavity 1311a, and then to the atomizing cavity 130a.

[0066] Generally, when the spray device 100 is installed on the hair dryer body 200, the liquid level in the first accommodating cavity 1311a may change due to the different placement positions of the hair dryer body 200, potentially resulting in the fluid level in the first accommodating cavity 1311a not reaching the height of the atomizing cavity 130a. Furthermore, within the first accommodating cavity 1311a, the pressure difference between the area near the atomizing cavity 130a and other areas of the first accommodating cavity 1311a is not significant, making it difficult for the fluid in the first accommodating cavity 1311a to directly enter the atomizing cavity 130a.

[0067] In this embodiment, when the atomizing element 132 is working, the atomizing chamber 130a draws in the fluid from the first accommodating chamber 1311a. This results in a higher fluid velocity and lower pressure in the area near the atomizing chamber 130a. At this time, the pressure in the second accommodating chamber 1313a is greater than the air pressure in the area near the atomizing chamber 130a. This allows the fluid in the second accommodating chamber 1313a to enter the area near the atomizing chamber 130a in the first accommodating chamber 1311a through the through hole 1311c, and be drawn into the atomizing chamber 130a, thereby achieving the atomization function. That is, in this embodiment, two atomizing chambers 130a can be formed, ensuring the atomization performance of the spray device 100 and improving the stability of the care effect of the hair dryer 10.

[0068] In some embodiments, one of the inner walls of the spray device 100 and the second cavity 220 is provided with a magnetic attraction portion, and the other is provided with a magnetic engagement portion. The magnetic attraction portion and the magnetic engagement portion are magnetically connected to connect the inner wall of the spray device 100 and the first cavity 210. Specifically, in one example, the polarities of the magnetic attraction portion and the magnetic engagement portion are set to opposite, thereby achieving magnetic engagement between the magnetic attraction portion and the magnetic engagement portion. In another example, the magnetic attraction portion can be an electromagnet or a permanent magnet, and the magnetic engagement portion is a metal portion, to achieve magnetic engagement between the magnetic attraction portion and the magnetic engagement portion.

[0069] Thus, through magnetic connection, the user can simply bring the spray device 100 close to the first cavity 210 of the hair dryer 10 to install the spray device 100 onto the hair dryer 10, completing the installation. Correspondingly, the user can simply pull the spray device 100 out forcefully to achieve magnetic separation from the first cavity 210 to complete the disassembly, facilitating cleaning or fluid replacement.

[0070] In other embodiments, such as Figures 7 to 9As shown, one of the inner walls of the spray device 100 and the first cavity 210 is provided with a snap-fit ​​portion 100a, and the other is provided with a snap-fit ​​mating portion 200a. The snap-fit ​​portion 100a and the snap-fit ​​mating portion 200a engage to connect the spray device 100 to the inner wall of the first cavity 210. Thus, the snap-fit ​​design, through the tight fit of the mechanical structure, ensures a stable and reliable connection between the spray device 100 and the first cavity 210, effectively preventing the spray device 100 from loosening or falling off during use, and avoiding damage to the spray device 100.

[0071] Furthermore, in one embodiment, see back Figure 8 as well as Figure 9 The inner wall of the first cavity 210 is provided with a snap-fit ​​part 200a. The snap-fit ​​part 200a includes two opposing elastic arms 200b, one end of which is rotatably mounted on the inner wall of the first cavity 210, and the two elastic arms 200b can move elastically in directions of approaching and moving away from each other. The inner side of the elastic arm 200b is provided with a recess 200c and a guide part 200d connected to the recess 200c. The spray device 100 is provided with a snap-fit ​​part 100a, which includes a snap-fit ​​body 100b and two protrusions 100c; the two protrusions 100c protrude from the two opposing sides of the snap-fit ​​body 100b. The protrusions 100c engage with the recess 200c through the guide part 200d.

[0072] To facilitate understanding, the installation process of the snap-fit ​​part 100a and the snap-fit ​​mating part 200a in an installation scenario will be explained in detail below.

[0073] like Figure 9 As shown, when the spray device 100 needs to be installed into the first cavity 210, the snap-fit ​​body 100b is gradually pushed in along the depth direction X close to the first cavity 210. At this time, the protrusion 100c slides and engages with the guide portion 200d, allowing the protrusion 100c to engage with the elastic arm 200b, causing the two elastic arms 200b to move in a direction away from each other. The recess 200c on the inner side of the elastic arm 200b engages with the protrusion 100c, realizing the snap-fit ​​connection between the snap-fit ​​portion 100a and the snap-fit ​​engagement portion 200a. After the snap-fit ​​portion 100a and the snap-fit ​​engagement portion 200a are engaged, the two elastic arms 200b move in a direction close to each other, allowing the sidewall of the recess 200c to abut against the protrusion 100c.

[0074] When it is necessary to separate the spray device 100 from the first cavity 210, the locking body 100b is pushed further along the depth direction X close to the first cavity 210, causing the protrusion 100c and the elastic arm 200b to further engage, causing the two elastic elements to move in a direction away from each other. At this time, the recess 200c separates from the protrusion 100c. Then, the locking body 100b is pulled away from the first cavity 210. Through the sliding engagement of the protrusion 100c with the guide portion 200d, the locking body 100b can be pulled out, realizing the separation of the spray device 100 from the first cavity 210.

[0075] In any embodiment of the working air duct 220a described above, the control component 300 includes a first power supply unit and a second power supply unit. The first power supply unit is used for electrical connection with the hair dryer body 200. The second power supply unit is used for electrical connection with the atomizing element 132. The spray device 100 is provided with a power receiving terminal. The spray device 100 is detachably connected to the second cavity 220. When the spray device 100 is installed in the second cavity 220, the power receiving terminal is electrically connected to the second power supply unit, so that the second power supply unit can supply power to the atomizing element 132, enabling the atomizing element 132 to atomize the fluid in the atomizing chamber 130a. When the spray device 100 is separated from the second cavity 220, the power receiving terminal is de-energized from the second power supply unit. Thus, through the detachable connection, the spray care function can be quickly turned on or off without complicated operation, improving the ease of use of the hair dryer 10.

[0076] Further, optionally, in one embodiment, when the spray device 100 is installed in the second cavity 220, the electrical connection is achieved by contacting the power receiving end with the second power supply part. Specifically, when the user needs to use the spray function, the spray device 100 is installed on the second cavity 220 of the blower body 200, so that the power receiving end contacts the power supply contact of the second power supply part. When the user does not need to use the spray function, the spray device 100 is disassembled, the power receiving end separates from the power supply contact, and the atomizing component 130 stops working. In this way, the contact-type electrical connection design between the power receiving end and the power supply contact ensures the reliability of the electrical connection and avoids problems such as short circuits that are prone to occur when electrical connections are made by wires.

[0077] In some embodiments, the hair dryer 10 further includes an air supply assembly 400, which is connected between the working air duct 220a and the first air inlet 123. A control assembly 300 is electrically connected to the air supply assembly 400 and is used to drive the air supply assembly 400 to blow air from the working air duct 220a to the first air inlet 123.

[0078] Thus, by setting up the air supply component 400, the flow resistance between the working air duct 220a and the air supply channel 122 can be overcome, thereby making the airflow jet from the first air outlet 121 more stable and uniform, thereby improving the uniformity of the gas mixing in the air supply channel 122 and the atomization chamber 130a, which is conducive to further improving the nursing performance of the spray device 100.

[0079] It should be noted that in this embodiment, the air supply direction implemented by the air supply component 400 can be the same as or different from the air direction in the working air duct 220a. It can be selected according to different production needs, and no further restrictions are imposed here.

[0080] Combination Figures 4 to 6 As shown, this application also provides a hair dryer 10, including the spray device 100, hair dryer body 200, control component 300, and air delivery component 400 in the above embodiments.

[0081] Specifically, the blower body 200 has a first cavity 210, a second cavity 220, a second air inlet 230, and a third air outlet 240. The second air inlet 230 and the third air outlet 240 are arranged opposite to and connected on both sides of the second cavity 220 to form a working air duct 220a. The first cavity 210 has an opening 211, and the opening 211 is connected to the mixing outlet 112. The first air inlet 123 is connected to the working air duct 220a.

[0082] like Figure 10 As shown, the air supply assembly 400 is disposed in the working air duct 220a. The air supply assembly 400 has a first side 410 and a second side 420 opposite each other along the depth direction X of the working air duct 220a. The first side 410 is disposed near the third air outlet 240. The second side 420 is disposed near the second air inlet 230. The air supply assembly 400 has a negative pressure channel 400a, the outlet of which is connected to the first air inlet 123. The negative pressure channel 400a is used to draw air from the working air duct 220a to its outlet, so that the air is discharged to the first air inlet 123 through the outlet of the negative pressure channel 400a. The outlet of the negative pressure channel 400a is disposed near the second side 420.

[0083] It should be noted that the negative pressure channel 400a refers to a low-pressure channel that is lower than the average air pressure in the second cavity 220, based on the average air pressure in the second cavity 220. This allows the air volume in the working air duct 220a to be drawn into the negative pressure channel 400a, so that the first air inlet 123 can be ventilated through the negative pressure channel 400a.

[0084] The control assembly 300 is mounted in the second cavity 220. The control assembly 300 includes a first power supply assembly 310 and a second power supply assembly 320. The first power supply assembly 310 supplies power to the hair dryer body 200. The second power supply assembly 320 supplies power to the air delivery assembly 400. The second power supply assembly 320 is located close to the first side 410.

[0085] Specifically, when the second power supply component 320 powers the air supply component 400, the negative pressure channel 400a can draw air from the working air duct 220a and transport it to the first air inlet 123. Correspondingly, when the second power supply component 320 does not power the air supply component 400, the air pressure of the negative pressure channel 400a and the working air duct 220a remains approximately balanced, and the negative pressure channel 400a will not actively draw air from the working air duct 220a.

[0086] Understandably, when the control component 300 powers the blower body 200, the working air duct 220a can generate a certain amount of air, enabling the blowing function. The working air duct 220a blows air through the third air outlet 240. At this time, since the working air duct 220a is connected to the first air inlet 123, it can also be connected to the air supply channel 122, allowing a portion of the airflow to be blown out from the first air outlet 121.

[0087] Furthermore, since the first air inlet 123 and the outlet of the negative pressure channel 400a are both located close to the second side 420, and the outlet of the negative pressure channel 400a is connected to the first air inlet 123, the flow distance between the first air inlet 123 and the outlet of the negative pressure channel 400a can be reduced, thereby reducing the size of components such as air ducts, which in turn is conducive to the miniaturization of the blower body 200.

[0088] Furthermore, the second power supply assembly 320 is positioned close to the first side 410, which reduces the spatial obstruction between the second power supply assembly 320 and the outlet of the negative pressure channel 400a, thereby ensuring the performance of each component and improving the stability of the hair dryer 10.

[0089] In some embodiments, such as Figure 6 as well as Figure 10 As shown, the outlet of the negative pressure channel 400a is located on the second side 420. In this way, the distance between the outlet of the negative pressure channel 400a and the first air inlet 123 can be minimized, which is beneficial to improving the integration performance of the air supply assembly 400 and the spray device 100, and thus beneficial to the miniaturization of the blower 10.

[0090] Furthermore, the first power supply component 310 is positioned close to the second side 420. Thus, the first power supply component 310 and the second power supply component 320 are positioned opposite each other on both sides of the air supply component 400, which optimizes the circuit layout, reduces circuit interference between the first power supply component 310 and the second power supply component 320, and improves the overall operational stability of the hair dryer 10.

[0091] It should be noted that the air supply component 400 in the above embodiments can be, but is not limited to, a fan assembly, an air pump, etc. In addition, the first power supply component 310 and the second power supply component 320 can be PCB (Printed Circuit Board), FPC (Flexible Printed Circuit), etc., or can be configured by multiple switching components. No further restrictions are placed on the former here.
