For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood on a case-by-case basis.

It is noted that features in embodiments of the present disclosure can be combined with each other without conflict.

As stated in the background art, existing applicator usually adopts absorbent material such as sponge, which, in use, needs to first adsorb the liquid on the surface of the material and then squeezes out the adsorbed liquid by pressing, which is inconvenient to operate with one hand when applying to the back.

In addition, the existing applicator needs to utilize the absorbency of the material when applying the liquid, so that the liquid adheres to the surface of the material, and the pressing force is put to squeeze out the liquid when applying, but the applicator will continue to adsorb the liquid after pressing, which leads to lower application efficiency, and thus the liquid cannot be fully utilized. The difficulty of cleaning sponge and other absorbent materials after absorption of liquid also increases. The contamination and hardening are inevitable after long-term use, which leads to be unusable.

Referring to FIG. 1-FIG. 7, the applicator and the application method provided in the embodiment of the present disclosure can solve the above problems, which will be described in detail next.

Referring to FIG. 1-FIG. 3, the applicator 100 includes: a connecting member 110, a drive member 130, a spray member 150, and an applicator head 170, wherein the drive member 130, the spray member 150, and the applicator head 170 are mounted to the connecting member 110, and the drive member 130 is configured to move relative to the connecting member 110 to drive the spray member 150 to spray liquid.

The applicator 100 in use can achieve the application effect by operating the drive member 130 to drive the spray member 150 to spray the liquid, and then moving the applicator head 170 to contact with the liquid, and it can improve the convenience of one-handed operation when applying to the back.

Notably, a cavity is provided within the spray member 150 to hold liquid, and the cavity can be filled with liquid in advance before the installation of the spray member 150, or the cavity can be connected with a pipeline, such that liquid is continuously filled in through the pipeline while the spray member 150 sprays the liquid.

Moreover, because the single movement stroke of the drive member 130 is relatively fixed, the amount of liquid sprayed from the spray member 150 in a single time is also relatively fixed, thereby making the amount of liquid used by the applicator 100 in the use easier to control.

Referring to FIG. 1 and FIG. 2, the applicator head 170 has a planar plate 172 and a spherical plate 171 provided oppositely to each other, and the applicator head 170 is rotatably connected to the connecting member 110, such that the planar plate 172 or the spherical plate 171 can be controlled to contact with the human body in the process of applying, and the planar plate 172 has the advantage of a large contact area with high efficiency of applying when being in contact with the human body, whereas the spherical plate 171, when being in contact with the human body, has the advantages of applying with high precision and high degree of comfort. Therefore the applying can be selected according to the part to be applied as well as the personal needs of user.

Specifically, the planar plate 172 and the spherical plate 171 can be detachably connected, which can specifically be a threaded connection or a snap connection. When one of them is worn out or damaged, it can be individually replaced by the detachable connection, thereby reducing the cost of use.

Notably, the applicator head 170 is rotatably connected to the shield portion 113, which can be that at least two slots are provided on the shield portion 113, and at least two blocks are provided on the inner wall of the applicator head 170 to cooperate with the slots, so as to realize adjusting the relative circumferential angles of the applicator head 170 and shield portion 113 by cooperating blocks with different slots.

Moreover, the materials of planar plate 172 and the spherical plate 171 can both be non-absorbent materials. The liquid is ejected through the spray member 150, so that there is no need to adsorb the liquid for squeezing and releasing. Moreover, the adsorption of the liquid during the application process is avoided, which may affect the application effect. Because the planar plate 172 and the spherical plate 171 do not adsorb liquid, the applicator head 170 is easy to clean and does not produce stubborn dirt due to liquid adsorption and residue. The planar plate 172 and the spherical plate 171 can be made of plastic or rubber, the specific materials of which are not limited.

Certainly, the applicator head 170 can be made of panels of other shapes, including but not limited to beveled panels, curved panels, and special-shaped panels, as long as it is ensured that at least a part of the outer wall of the applicator head 170 is capable of contacting the application site, and the specific shapes of the constituent panels are not limited.

The end of the shield portion 113 away from the extension portion 112 is connected to the applicator head 170, and the end of the handle portion 111 away from the extension portion 112 is of a closed structure to avoid interference with the drive portion inside the handle portion 111. During use, the palm of the user can directly hold the handle portion 111 and then turn or rotate the drive portion through the fingers.

In this embodiment, the entire connecting member 110 is cylindrical, i.e., the connecting member 110 has a circular cross-section.

Notably, the rectifying ring 155 and the third segment 1523 can be in an interference fit or a threaded connection, and the specific connection mode between these two is not limited.

Referring to FIG. 3 and FIG. 4, the spray member 150 also includes a spring 156, which is installed in the inner cavity of the inner cylinder 152, and the two ends of the spring 156 are connected to the rectifying ring 155 and the pressing head 151 respectively. By providing the spring 156, on the one hand, the relative distance between the pressing head 151 and the rectifying ring 155 can be limited to prevent the distance between the two from being too small or too large; on the other hand, the spring 156 can exert an elastic tension or elastic pulling force on the pressing head 151, so that the kinetic energy of the pressing head 151 gradually decreases in the process of moving away from the rectifying ring 155, and the kinetic energy of the pressing head 151 also gradually decreases in the process of approaching the rectifying ring 155.

In addition, in the case where the user turns the toggle 131, the spring 156 can be synchronously stretched by the transmission rob 132 driving the pressing head 151 to move away from the rectifying ring 155, so that negative pressure is formed in the inner cylinder 152, and the liquid is pumped from the tank 1541 to the inner cylinder 152 through the liquid tube 1542; after the user disengages from the toggle 131, the spring 156 can be driven by its own elasticity to bring the pressing head 151 close to the rectifying ring 155, to exert a squeezing effect on the inner cylinder 152, such that the liquid in the inner cylinder 152 is sprayed out through the nozzle 153.

Referring to FIG. 3 and FIG. 4, the pressing head 151 comprises a pressing plate 1511, a guide plate 1512, and a carrier plate 1513 connected in sequence, wherein the pressing plate 1511 cooperates with the inner cylinder 152 and the carrier plate 1513 is connected to the drive member 130. Specifically, the pressing plate 1511 cooperates with the first segment 1521, the carrier plate 1513 is connected to the transmission rod 132, and the guide plate 1512 can be provided between the pressing plate 1511 and the carrier plate 1513 to avoid making the pressing head 151 be a solid structure, such that the material used is reduced in the case of ensuring the strength, thereby reducing the production cost.

Referring to FIG. 3 and FIG. 4, the end surface of the carrier plate 1513 abuts against the end surface of the inner cylinder 152; specifically, the end surface of the carrier plate 1513 abuts against the end surface of the first segment 1521, and axial movement of the pressing head 151 can be limited by the cooperation between the carrier plate 1513 and the end surface of the first segment 1521.

In this embodiment, both the pressing plate 1511 and the carrier plate 1513 are of a circular disc structure, and the thickness of the pressing plate 1511 is greater than the thickness of the carrier plate 1513. Certainly, it is also possible to make the thickness of the pressing plate 1511 less than or equal to the thickness of the carrier plate 1513, while ensuring structural strength.

Referring to FIG. 4, the guide plate 1512 is of a bifurcated structure; specifically, the guide plate 1512 is of a cross structure, i.e., the cross-section of the guide plate 1512 is cross-shaped. Certainly, under the premise of ensuring sufficient structural strength, the guide plate 1512 can also be cylindrical or prismatic, i.e., the cross-section of the guide plate 1512 can be circular, oval, prismatic, rectangular, triangular, and pentagonal, etc., and the specific shape of the guide plate 1512 is not limited.

Moreover, the guide plate 1512 includes a plurality of sub-plates, and the width of the end of each sub-plate close to the pressing plate 1511 is smaller than the width of the end of the guide plate 1512 close to the carrier plate 1513, such that the sub-plates and the entire guide plate 1512 present a certain streamlined shape in the axial direction, on the one hand, to fit with the shape of the pressing plate 1511 and the carrier plate 1513, and on the other hand, to facilitate the flow of the airflow between the pressing plate 1511 and the carrier plate 1513, thereby avoiding that the airflow gathers between these two.
