As shown in fig. 2 to 4, the spout sealing assembly 5 includes a mounting member 51 and a sealing member 52, the mounting member 51 is provided with a mounting portion 511, the mounting member 51 is used to be connected with the button member 4 of the spraying device 100, the sealing member 52 is fixed to the mounting portion 511, and the sealing member 52 is connected with the button member 4 through the mounting member 51. When the spraying device 100 is in the initial state, the sealing member 52 seals the nozzle 311 of the spraying device 100 to prevent bacteria from growing in the nozzle 311 in contact with the external environment. When the button member 4 is moved under an external force to trigger the spray, the mounting member 51 moves in synchronization with the button member 4 to carry the seal member 52 away from the spout 311 such that the spout 311 is opened to fit the spray. When the button member 4 is reset, the mount member 51 is synchronously reset so that the seal member 52 reseals the spout 311. It should be appreciated that the seal 52 moves in at least one direction away from the spout 311, including movement in at least one of an up-down direction, a back-and-forth direction, and a left-right direction.

Through adopting above-mentioned technical scheme, spout seal assembly 5 can make seal 52 along with button piece 4 synchronous motion when installing seal 52 through setting up mounting piece 51, consequently, atomizer 100 can open spout 311 by oneself at the in-process spout seal assembly 5 that triggers the spraying, can seal spout 311 by oneself after spraying finishes, and need not the user and seal with hands, easy and simple to handle can last to maintain sealing performance effectively.

In an embodiment, as shown in fig. 1 and 3 to 5, the button member 4 is a housing structure, which is covered on the upper portion of the pump body assembly, and the button member 4 is pressed downward to trigger spraying, so as to fit the usage habit of a user. Of course, the setting position of the button member 4 is not limited to this, and may be set on any side of the pump body assembly, for example, on the lower portion of the pump body assembly, so that when the user uses the spraying device, the bottom of the button member 4 of the spraying device 100 may be placed on the surface (such as a table top) of an object, and the top surface of the spraying device 100 may be pressed downward, so that spraying may be triggered. At this time, the seal 52 moves downward to be away from the spout 311.

In one embodiment, as shown in fig. 1 and 3, the spraying device 100 further includes a housing 6, the button member 4 is partially located in the housing 6, and the button member 4 is exposed to the housing 6 for being pressed by a user. The pump body assembly, the nozzle assembly 3 and the spout seal assembly 5 are all provided to the housing 6 to enhance the aesthetic appearance of the spray device 100.

Further, the spraying device 100 further comprises an actuating mechanism (not shown in the figure), the button member 4 is slidably connected to the housing 6, the button member 4 is connected to the actuating mechanism, the button member 4 can move downward under the action of the actuating mechanism to trigger spraying, and when the external force is removed, the button member 4 can be reset under the action of the actuating mechanism.

Further, the actuating mechanism at least comprises an elastic member, the button member 4 is compressed under the pressing, and when the external force is removed, the elastic member is reset to reset the button member 4.

In an embodiment, as shown in fig. 2, 4 and 5, the mounting portion 511 has a groove structure, the sealing member 52 is embedded in the mounting portion 511, and the sealing member 52 is assembled simply and quickly. Of course, the structure of the mounting portion 511 is not limited thereto, and may be other mounting structures capable of mounting the seal 52, such as mounting holes or a snap-fit structure.

In one embodiment, as shown in fig. 2, 3 and 5, a surface of the mounting member 51 facing away from the sealing member 52 is provided with a protrusion 512, and the spraying device 100 includes a housing 6, and a surface of the housing 6 facing the mounting member 51 is provided with a first pressing portion 611. When the spraying device is in the initial state, the protrusion 512 abuts against the first abutting portion 611, and the first abutting portion 611 applies a force to the protrusion 512 in a direction towards the nozzle assembly 3, so that the sealing member 52 is pressed against the nozzle 311, and the tightness of the sealing member 52 against the nozzle 311 is improved. When the spraying apparatus 100 is in the triggered state, the movement direction of the mounting member 51 is perpendicular to the axial direction of the nozzle 311, and during the movement of the mounting member 51 to bring the sealing member 52 away from the nozzle 311, the protrusion 512 is separated from the first pressing portion 611, and the force exerted on the protrusion 512 by the first pressing portion 611 is removed, so that the protrusion 512 moves in the axial direction of the nozzle 311 in a direction away from the nozzle 311, and the protrusion 512 drives the sealing member 52 to move in two directions (the direction of the axial direction away from the nozzle 311 and the direction perpendicular to the axial direction of the nozzle 311) so that the sealing member 52 is separated from the nozzle 311.

Further, the mounting member 51 is an elastic member, and the mounting member 51 has a certain elastic deformation capability, so that the protrusion portion 512 can make the mounting member 51 press against the spout 311 under the pressing force of the first pressing portion 611, and further make the sealing member 52 press against the spout 311.

It should be appreciated that the mounting member 51 may be a plastic structure with certain elastic deformability due to the material characteristics. Of course, the mounting member 51 may also be constructed as a relatively thin plate-like structure to provide some elastic deformability.

Further, in one embodiment, as shown in fig. 3, the protruding portion 512 is one, and the mounting portion 511 and the protruding portion 512 are distributed along the center line of the mounting member 51 in the up-down direction, so that the pressing force of the first pressing portion 611 received by the protruding portion 512 can be uniformly transmitted to the mounting portion 511.

In still another embodiment, as shown in fig. 5, two protrusions 512 are provided, and the two protrusions 512 are located on two sides of a surface of the mounting member 51 facing away from the sealing member 52, so that the pressing force of the first pressing portion 611 received by the protrusions 512 can be uniformly transmitted to the mounting portion 511.

Of course, the number and the arrangement positions of the protruding portions 512 are not limited thereto, and it is preferable that the protruding portions 512 be arranged so that the pressing force of the first pressing portion 611 to which they are subjected is uniformly transmitted to the mounting portion 511.

In one embodiment, as shown in fig. 2 and 4, a surface of the housing 6 facing the mounting member 51 is provided with a groove 612, and the groove 612 is connected to the first pressing portion 611. In a specific embodiment, the button member 4 is located at the upper portion of the nozzle assembly 3, and when an external force presses the button member 4, the button member 4 moves downward to trigger spraying, the mounting member 51 moves downward along with the button member 4, so that the protruding portion 512 is separated from the first pressing portion 611, and the mounting member 51 continues to move downward so that the protruding portion 512 of the mounting member 51 enters the recess 612. The recess 612 is configured to receive the boss 512 so as to reduce the force with which the mounting member 51 presses the seal 52 against the spout 311 so that the mounting member 51 continues to move downwardly, eventually completely disengaging the seal 52 from the spout 311.

Further, as shown in fig. 2 and 4, the surface of the first pressing portion 611 for pressing the protruding portion 512 is a slope, which extends obliquely in a direction toward the groove 612. The first pressing portion 611 can press the protruding portion 512, and the first pressing portion 611 can also play a guiding role when spraying is triggered, so that the protruding portion 512 is separated from the first pressing portion 611 and enters the groove 612, and thus, a user can trigger spraying easily without applying excessive force to drive the button member 4 to move together with the spout sealing assembly 5.

Of course, the structures of the mount 51 and the housing 6 are not limited thereto, the mount 51 may not be provided with the boss 512, the housing 6 may not be provided with the first pressing portion 611 and the groove 612, and the seal 52 may be enabled to seal the spout 311 by defining the fitting gap between the mount 51 and the nozzle assembly 3. And, when the spray is triggered and the mount 51 moves in synchronization with the button 4, the seal 52 is pressed between the mount 51 and the nozzle assembly 3, enabling the mount 51 to move in synchronization with the button 4 under flexible deformation of the seal 52. In this embodiment, the mounting member 51 may be an elastic member or a non-elastic member.

Further, as shown in fig. 2 and 3, the spraying device 100 further includes a mounting bracket 71, and the mounting bracket 71 is used to fixedly hold a bottle. The mounting bracket 71 is provided with a second pressing portion 711, and the second pressing portion 711 is pressed against the mounting member 51. When the atomizing device 100 triggers the spraying, the mounting member 51 moves along with the button member 4 until the protrusion portion 512 is separated from the first pressing portion 611, at this time, the groove 612 can yield the movement of the protrusion portion 512 away from the nozzle 311, and a force directed away from the nozzle 311 is applied to the mounting member 51 by the second pressing portion 711, so as to push the mounting member 51 away from the nozzle 311, so that the mounting member 51 continues to move.

Further, as shown in fig. 2 and 3, the second pressing portion 711 has a convex structure, and is simple in structure. The second pressing portion 711 extends obliquely in a direction toward the mount 51, and can apply a force to the mount 51 in a direction away from the spout 311.

Further, the second pressing portion 711 is an elastic member, and the second pressing portion 711 has a certain elastic deformability. In this way, the second pressing portion 711 is capable of deforming in the axial direction of the spout 311 to match the change in the position of the mount 51 in the axial direction of the spout 311 during the reciprocation.

Of course, the second pressing portion 711 may be a non-elastic member, and in this case, the mounting member 51 is an elastic member, and when the spraying device 100 is in the initial state, the mounting member 51 is pressed by the nozzle assembly 3 and the housing 6 so that the sealing member 52 can be pressed against the nozzle 311. When the spraying device 100 triggers spraying, the mounting member 51 is pressed by the second pressing portion 711, and the portion of the mounting member 51 opposite to the groove 612 can be stretched, so that the friction between the mounting member 51 and the housing 6 can be reduced, which is beneficial for the continuous movement of the mounting member 51.

In one embodiment, as shown in fig. 1 to 3, the button member 4 is located at an upper portion of the nozzle assembly 3, and the mounting bracket 71 is located below the nozzle assembly 3. The mounting portion 511 is disposed above the protruding portion 512, the protruding portion 512 is disposed near the bottom end of the mounting member 51, and the second pressing portion 711 abuts against a lower portion of a surface of the mounting portion 511 facing the nozzle 311.

In one embodiment, as shown in fig. 4 and 5, the button member 4 and the mounting member 51 are integrally formed, and the assembly process of both members is omitted.

In one embodiment, as shown in fig. 2 to 4, the mounting member 51 is provided with a through hole 513, and the housing 6 is provided with an outlet 613. When spraying is triggered, the mounting member 51 moves to the seal member 52 to open the spout 311, at which point the through-hole 513 and the outlet 613 are aligned, thereby opening the spout 311 and spraying the nozzle assembly 3 from the outlet 613. The spraying device 100 comprises an actuating mechanism for driving the button member 4 to reciprocate, the actuating force of the actuating mechanism is controlled to control the travel distance of the button member 4, and the travel distance control of the button member 4 is used to realize the alignment of the through hole 513 and the outlet 613, so that the accurate triggering is finally realized.

It should be understood that the above examples are illustrative and are not intended to encompass all possible implementations encompassed by the claims. Various modifications and changes may be made in the above embodiments without departing from the scope of the disclosure. Likewise, the individual features of the above embodiments can also be combined arbitrarily to form further embodiments of the invention which may not be explicitly described. Therefore, the above examples merely represent several embodiments of the present invention and do not limit the scope of protection of the patent of the present invention.
