As shown in fig. 1 to 10, as an embodiment of the present invention, a portable sprayer is disclosed, which can be used in nasal cavity, oral cavity, etc. of a human body, and can contain a liquid medicine for treating nasal or oral diseases, or a liquid such as perfume, essential oil, freshener, etc. in the sprayer, and has refreshing and refreshing effects. The sprayer mainly comprises a sprayer body 4 and an outer shell 5, wherein the sprayer body 4 is used for atomizing liquid and spraying the liquid to the outside, and comprises an inner shell 1 with a hollow cavity, a liquid storage container 21 and a control circuit, the liquid storage container 21 and the control circuit are positioned in the hollow cavity, the inner shell 1 is set to be of a circular structure with a first axis, a fixing seat 6 protruding along the first axis is arranged on the end surface of the shaft of the inner shell 1, and a spray nozzle 223 communicated with the liquid storage container 21 and an operation key 31 connected with the control circuit are arranged on the circumferential end surface of the inner shell 1; in addition, the outer shell 5 is provided with a fan-shaped structure with a second axis, the second axis and the first axis are arranged along the same axis, the outer shell 5 is sleeved on the periphery of the local inner shell 1 through the fixing seat 6, and can rotate along the circumferential direction relative to the inner shell 1 to shield or expose the atomizing nozzle 223 and the control key 31. In this embodiment, liquid storage container 21 and control circuit have been hidden in atomizer body 4, and the radius of shell 5 slightly is greater than the radius of inner shell 1 to shell 5 can overlap and establish on inner shell 1, therefore the overall structure of atomizer arranges rationally compactly, and the appearance of atomizer is the round structure, and convenient to use person's accomodation and go out to carry the use. In the process of using the sprayer, the outer shell 5 rotates relative to the inner shell 1 and is located at any rotating position relative to the inner shell 1 by taking the second axis or the first axis as a rotating axis so as to expose or shield the spray nozzle 223 and the control button 31. When the user need not use the atomizer, the user can rotate shell 5 to the position that shelters from atomising nozzle 223 and control button 31, avoids atomising nozzle 223 to expose externally on the one hand like this, avoids outside dust and bacterium to depend on atomising nozzle 223, and on the other hand avoids the user to touch by mistake and controls button 31, causes unnecessary trouble, simple structure and design hommization. Further, in some embodiments, the inner housing 1 is further provided with a first positioning structure 42, the outer housing 5 is provided with a second positioning structure 43 moving synchronously with the outer housing 5, the first positioning structure 42 and the second positioning structure 43 can be mutually attracted and constrained to limit the rotation of the outer housing 5 relative to the inner housing 1, the outer housing 5 can be in a first position for shielding the spray nozzle 223 and the control button 31, or in a second position for exposing the spray nozzle 223 and the control button 31, therefore, during the actual use of the sprayer, when the user drives the outer housing 5 to rotate relative to the inner housing 1, the second positioning structure 43 and the outer housing 5 move synchronously, and the first positioning structure 42 is fixedly arranged on the inner housing 1, so that when the second positioning structure 43 is gradually close to the first positioning structure 42, the two structures are mutually constrained to form a positioning, thereby limiting the rotation of the outer housing 5 relative to the inner housing 1, the casing 5 can be in a first position in which it shields the spray nozzle 223 and the control button 31, so as to facilitate the user to take in the sprayer or carry it out, or the casing 5 can be in a second position in which the spray nozzle 223 and the control button 31 are exposed, so as to facilitate the user to use the sprayer; similarly, when the second positioning structure 43 is gradually far away from the first positioning structure 42, the two positioning structures are separated from each other to be in an active adjustment state. Therefore, in the present invention, the outer shell 5 is rotatably disposed relative to the inner shell 1, so as to prevent the spray nozzle 223 from being exposed to the outside and prevent the user from touching the operation button 31 by mistake, thereby improving the hygiene and safety, and in addition, by the arrangement of the first positioning structure 42 and the second positioning structure 43, the rotation of the outer shell 5 relative to the inner shell 1 is prevented from being too smooth, so that the rotation angle and position of the outer shell 5 relative to the inner shell 1 can be controlled, so that even under the effect of no supporting force of hands, the outer shell 5 can be positioned to the first position or the second position relative to the inner shell 1, the adjustment can be controlled, and the structural stability is good.

As another embodiment of the present invention, the first positioning structure 42 includes a first magnet 71 and a second magnet 72 located on the axial end surface 411 of the inner casing, and the first magnet 71 and the second magnet 72 are arranged along the vertical direction of the axial end surface 411 of the inner casing and are distributed symmetrically up and down; furthermore, the second positioning structure 43 is provided as a third magnet 73 on the housing axial end face 53, the third magnet 73 being synchronously movable with the housing 5 and being arranged in correspondence with the first magnet 71 or the second magnet 72, the housing axial end face 53 and the inner housing axial end face 411 being arranged parallel to one another. Therefore, in the present embodiment, the first positioning structure 42 mainly includes a first magnet 71 located above the inner housing axial end surface 411 and a second magnet 72 located below the inner housing axial end surface 411, the first magnet 71 and the second magnet 72 are both fixedly connected to the inner housing axial end surface 411, and an angle between the first magnet 71 and the second magnet 72 is 180 degrees; the second positioning structure 43 is configured as a third magnet 73 fixed on the end surface 53 of the housing shaft, so that the third magnet 73 and the first magnet 71 are attracted and restrained when the outer housing 5 rotates to the first position relative to the inner housing 1 during some specific uses of the sprayer; or when the outer shell 5 rotates to the second position relative to the inner shell 1, the third magnet 73 and the second magnet 72 are attracted and constrained with each other, and the rotation angle of the outer shell 5 from the first position to the second position is 180 degrees. Further, the atomizing nozzle 223 and the operation button 31 are close to the first magnet 71, so that when the third magnet 73 rotates to the second position, and the third magnet 73 and the second magnet 72 are attracted and restrained with each other, the housing 5 rotates upward and shields the atomizing nozzle 223 and the operation button 31 above, and similarly, when the third magnet 73 rotates to the first position, and the third magnet 73 and the first magnet 71 are attracted and restrained with each other, the housing 5 rotates downward and exposes the atomizing nozzle 223 and the operation button 31 above, so that a user can adjust and control when rotating the housing 5, and the magnets are restrained and positioned with each other, thereby facilitating the user to use or close the atomizer.
