[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0046] The present utility model embodiment provides an atomizer 1000, such as Figures 1 to 4 As shown, the atomizer 1000 includes a housing 10, an air pump 20, an atomizing structure 30 and an external battery assembly 40. The housing 10 is provided with an installation cavity 11, a liquid storage cavity 12 and a mist outlet 13 connected to the liquid storage cavity 12. The liquid storage cavity 12 is arranged on one side of the installation cavity 11, and the liquid storage cavity 12 is used to store liquid medicine. A first magnetic component 14 is installed on the housing 10; the air pump 20 is installed in the installation cavity 11; the atomizing structure 30 is arranged in the liquid storage cavity 12, and the atomizing structure 30 is connected to the air pump 20 and the mist outlet 13; the external battery assembly 40 is provided with a second magnetic component 41, and the second magnetic component 41 is attracted to the first magnetic component 14, so that the external battery assembly 40 can be detachably installed on the outside of the housing 10, and the external battery assembly 40 is electrically connected to the air pump 20 to supply power to the air pump 20.

[0047] The nebulizer 1000 of the present application can not only provide nebulization treatment for the user, but also be convenient for the user to carry, and has better portability.

[0048] Specifically, the air pump 20 acts on the atomization structure 30 to generate compressed air, guides the liquid medicine in the liquid storage chamber 12 to flow into the atomization structure 30 and realizes liquid atomization, and the atomized liquid medicine is discharged from the mist outlet 13 to the outside of the housing 10, thereby providing atomization treatment for the user. In addition, the atomizer 1000 uses an external battery assembly 40 installed on the outside of the housing 10 to power the air pump 20. Compared with the embodiment of the atomizer using a built-in battery in the prior art, the external battery assembly 40 reduces the occupation of the internal space of the housing 10, and the external battery assembly 40 will not have a negative impact on the layout of the internal components of the housing 10, so as to improve the utilization rate of the internal space of the housing 10, and then when the housing 10 is manufactured, the size of the housing 10 is made smaller and convenient to carry.

[0049] In addition, in the present application, the external battery assembly 40 is detachably connected to the housing 10. The user can place the external battery assembly 40 and the housing 10 as a whole according to the actual storage space size, or separate the two and place them separately, which is more flexible for users when traveling or carrying for daily use.

[0050] It is worth mentioning that the detachable connection between the external battery assembly 40 and the housing 10 is achieved by magnetic attraction between the first magnetic member 14 and the second magnetic member 41. The magnetic connection provides a quick and convenient connection method without complicated operations or additional tools. Just bring the two parts close together to automatically adsorb them together, making assembly and disassembly faster.

[0051] In the present application, the mist outlet 13 is used to be combined with a mask 60 or a mouthpiece, and the mask 60 or the mouthpiece can ensure that the atomized medicine liquid directly enters the user's oral cavity and respiratory tract, thereby improving the absorption efficiency and therapeutic effect of the medicine.

[0052] Reference Figures 4 to 5 In one embodiment, a first conductive contact 42 is installed on the housing 10, the first conductive contact 42 is electrically connected to the air pump 20, and the first conductive contact 42 is exposed on the outer surface of the housing 10; the external battery assembly 40 includes a battery compartment 43 and a battery 44 installed in the battery compartment 43, and a second conductive contact 15 and a second magnetic member 41 are installed on the battery compartment 43, the second conductive contact 15 is electrically connected to the battery 44, and the second conductive contact 15 is exposed on the outer surface of the battery compartment 43, so that the first conductive contact 42 can be used in conjunction with the second conductive contact 15. In this way, when the first magnetic member 14 and the second magnetic member 41 are attracted to each other, the first conductive contact 42 and the second conductive contact 15 are directly in contact with each other, so that the electrical connection between the air pump 20 and the battery 44 is realized, and the battery 44 can power the air pump 20 more conveniently and quickly without complicated operations.

[0053] In this embodiment, the battery compartment 43 can provide protection for the battery 44 to prevent damage to the battery 44. The battery compartment 43 includes a cover plate and a shell, the second conductive contact 15 and the second magnetic member 41 are both arranged on the cover plate, and the shell is covered on the cover plate to enclose a space for accommodating the battery 44. The connection between the cover plate and the shell can be threaded or snap-fit, which is not limited here.

[0054] Reference Figure 4 In one embodiment, a mounting groove 161 is provided on the outer surface of the housing 10, the first conductive contact 42 and the second magnetic member 41 are both provided at the bottom of the mounting groove 161, the battery compartment 43 is provided with a boss 431, the first conductive contact 42 and the second magnetic member 41 are provided on the boss 431, and the mounting groove 161 is adapted to the outer contour of the boss 431 to limit the mounting boss 431. Such a configuration makes it more convenient for users to connect the external battery assembly 40 with the housing 10 and the connection can be more secure. Specifically, the outer periphery of the mounting groove 161 can facilitate the user to align, and when connecting, it is only necessary to roughly align the outer contour of the boss 431 with the mounting groove 161, and the external battery assembly 40 can be quickly positioned and connected with the housing 10. In addition, since the boss 431 is accommodated in the mounting groove 161, the groove wall of the mounting groove 161 limits the boss 431, making it easy to shift, and the reliability of the connection between the two is better.

[0055] In this embodiment, the installation groove 161 and the boss 431 are both in an arch shape to facilitate the user to identify the installation direction.

[0056] Reference Figure 4 In one embodiment, the housing 10 is further provided with an input interface 17, and the input interface 17 is electrically connected to the second conductive contact 15 and / or the air pump 20. With such a configuration, the power supply method of the atomizer 1000 is more flexible. Specifically, the input interface 17 can be a USB interface, through which the air pump 20 can be directly powered or the battery 44 can be charged, and the user can choose a suitable power supply method according to actual needs. Moreover, the advantage of such a design is that when the battery 44 is low on power, it can be directly powered through the input interface 17 to ensure that the atomizer 1000 continues to operate and extend its use time.

[0057] Reference Figure 1 In one embodiment, the housing 10 includes a base 16 and a liquid medicine tank 18, the mounting cavity 11 is disposed in the housing 10, the first magnetic member 14 is mounted on the housing 10, the liquid medicine tank 18 is detachably connected to the base 16, the liquid storage cavity 12 is disposed in the liquid medicine tank 18, and the mist outlet 13 is disposed on a side of the liquid medicine tank 18 away from the base 16. In this way, the detachable liquid medicine tank 18 makes cleaning and maintenance more convenient. The user can easily remove the liquid medicine tank 18 for cleaning, avoid residue or bacterial growth, and keep the atomizer 1000 hygienic.

[0058] There are many ways to detachably connect the liquid medicine tank 18 and the base 16. For example, refer to Figures 6 to 9 In the present application, a circular slot 162 is provided on the base 16, and a connecting seat 181 is provided on the side of the medicine tank 18 facing the circular slot 162; the outer contour of the connecting seat 181 is adapted to the circular slot 162, and a limiting protrusion 181a is provided on the outer peripheral surface of the connecting seat 181. A limiting groove 163 is provided on the groove wall of the circular slot 162, and the limiting groove 163 includes a receiving portion 163a and a limiting portion 163b. The receiving portion 163a is connected to the end of the base 16 facing the medicine tank 18, and the limiting portion 163b is connected to the position of the receiving portion 163a away from the medicine tank 18, and extends in the circumferential direction of the circular slot 162 to limit the installation of the limiting protrusion 181a. The medicine tank 18 is locked or unlocked with the base 16 by rotation, and the connection operation is more convenient and efficient.

[0059] Specifically, when the connecting seat 181 is inserted into the circular slot 162, the limiting protrusion 181a is inserted into the accommodating portion 163a and moves to the end of the accommodating portion 163a away from the medicine liquid tank 18. The accommodating portion 163a can guide the limiting protrusion 181a to a predetermined position to facilitate the subsequent cooperation between the limiting protrusion 181a and the limiting portion 163b. The connecting seat 181 is adapted to the circular slot 162 to facilitate its rotation along the circumference of the circular slot 162. The limiting protrusion 181a is transferred to the limiting portion 163b, and the limiting portion 163b limits the limiting protrusion 181a, so that the medicine liquid tank 18 is firmly connected to the base 16.

[0060] Further, refer to Figure 8 and Fig. 9 The atomizer 1000 further includes a positioning structure 50, which includes a clamping block 51 and a clamping groove 52. The clamping block 51 is disposed at one of the limiting protrusion 181a and the limiting portion 163b, and the clamping groove 52 is disposed at the other of the limiting protrusion 181a and the limiting groove 163. When the limiting protrusion 181a is accommodated in the limiting portion 163b, the clamping block 51 is clamped with the clamping groove 52. In this way, the clamping of the clamping block 51 and the clamping groove 52 can prevent the limiting protrusion 181a from returning to the accommodating portion 163a, so as to further improve the reliability of the connection between the liquid medicine tank 18 and the base 16.

[0061] Preferably, in the present application, the clamping block 51 has an arcuate surface 511 , and the arcuate surface 511 has a small contact area with the limiting portion 163 b of the limiting groove 163 , which can facilitate its insertion into the clamping groove 52 for clamping.

[0062] Reference Figure 3 and Fig.10In one embodiment, the liquid medicine tank 18 includes a cup body 182 and a cover body 183.

The cover body 183 is also provided with a liquid injection port 183a, which is connected to the liquid storage cavity 12. The liquid injection port 183a is used to add liquid medicine to the liquid storage cavity 12. With this arrangement, the liquid medicine tank 18 adopts a split design, which facilitates the assembly of the atomization structure 30 to the liquid storage cavity 12.

[0063] Preferably, in this embodiment, the cup body 182 can be made of a transparent material to facilitate the user to observe the remaining amount of the medicine in the medicine tank 18 and to facilitate the user to add medicine in time.

The barrier sheet 31 is blocked on the side of the outlet 331 facing away from the air inlet 321. With such arrangement, the air pump 20 generates compressed air to generate negative pressure between the air inlet 321 and the guide channel 332 , sucking the liquid medicine upwards, flowing from the guide channel 332 to the outlet 331 for spraying, and then colliding with the barrier sheet 31 to become extremely fine mist and be discharged to the mist outlet 13 .

[0067] Specifically, the first hollow cone 32 is disposed at the center of the cup body 182 and is integrally formed with the cup body 182, and the second hollow cone 33 is integrally formed with the barrier sheet 31 to facilitate manufacturing and reduce the number of parts. The barrier sheet 31 is fixedly connected to the cover body to avoid misalignment with the first hollow cone 32 to affect the atomization effect.

[0068] Preferably, in the present application, the bottom of the cup body 182 is in an inverted cone shape, and one end of the flow guide 332 is located at the bottom of the inverted cone. The medicine liquid can always be at one end of the flow guide 332, which facilitates the medicine liquid to be sucked away and enables the medicine liquid to be fully atomized and utilized.

[0069] Furthermore, the liquid medicine tank 18 further includes a mounting tube 184, which is arranged around the injection port 183a and close to the air inlet 321. A buckle block 184a is arranged on the inner wall of the mounting tube 184, and a hook column 311 is arranged on the barrier sheet 31. The hook column 311 extends into the mounting tube 184 and is engaged with the buckle block 184a. This arrangement facilitates the quick connection and disassembly of the barrier sheet 31 and the liquid medicine tank 18.

[0070] Specifically, two hook posts 311 and two buckle blocks 184 a are provided, and the two hook posts 311 are arranged back to back and cooperate with the corresponding buckle blocks 184 a to ensure better connection stability.

[0071] Preferably, in this embodiment, the liquid injection port 183a is arranged at the center of the cover body and is coaxially arranged with the air inlet 321 of the first hollow cone 32, and the mounting tube 184 is arranged on the side of the cover body facing the cup body 182 and extending toward the first hollow cone 32. When the hook column 311 is engaged with the buckle block 184a, the barrier sheet 31 and the second hollow cone 33 can be on the same axis as the liquid injection port 183a, and then after the cover body is installed to the cup body 182, the second hollow cone 33 can be quickly aligned with the first hollow cone 32, thereby simplifying the assembly steps and making the design more reasonable.
