[0048] Embodiment

[0049] An embodiment of the present application provides an application device, as Figures 1 to 10 shown, including: an applicator 1 and a tube body 32;

[0050] The tube body 32 is communicated with a liquid outlet nozzle 321;

[0051] An accommodation space 13 for accommodating a refrigerant is formed inside the applicator 1. A first through hole 14 matching the liquid outlet nozzle 321 is provided on the applicator 1. One side of the applicator 1 away from the tube body 32 has an application surface 15;

[0052] The applicator 1 is detachably connected to the tube body 32, and the liquid outlet nozzle 321 passes through the first through hole 14 to connect to the application surface 15.

[0053] Understandably, the detachable connection has strong flexibility in use, can be applied to the application requirements of more application scenarios, facilitates the combined use or separate use of the applicator 1 and the tube body 32, and further facilitates the cleaning and maintenance between the tube body 32 and the applicator 1.

[0054] At the same time, due to the detachable connection between the applicator 1 and the tube body 32, the applicator 1 can be separately taken and placed in a cold space environment, such as cooled in a refrigerator, rather than putting the entire application device into the refrigerator, which will not affect the normal storage and use of skin care products, thereby optimizing the actual use experience of users.

[0055] The liquid outlet nozzle 321 passes through the first through hole 14 to connect to the application surface 15, facilitating the skin care products stored in the tube body 32 to directly reach the application part through the channel formed by the liquid outlet nozzle 321, effectively cooperating with the applicator, and further contributing to achieving a good application effect.

[0056] Furthermore, as Figure 1 , Figure 6 and Figure 9 shown, the applicator 1 includes a first groove body 11, a second groove body 12 and a sheath 2. The first groove body 11 is sleeved on the second groove body 12 to form an accommodation space 13;

[0057] The first groove body 11 is sleeved on the second groove body 12, the notch of the first groove body 11 is oppositely arranged to the notch of the second groove body 12. Both the first groove body 11 and the second groove body 12 are provided with a first through hole 14. The wall bodies of the first groove body 11 and the second groove body 12 close to the first through hole 14 are inner side wall bodies 81, and the wall bodies far from the first through hole 14 are outer side wall bodies 82. At least one of the inner side wall bodies 81 and the outer side wall bodies 82 is provided with an abutting portion 42;

[0058] The sheath 2 is connected to the first groove body 11. The end of the sheath 2 far from the first groove body 11 is provided with a locking portion 41. The locking portion 41 is used to lock the applicator 1 to the tube body 32, and make the sheath 2 squeeze the first groove body 11 and / or the second groove body 12, so that the adjacent abutting portions 42 are closely attached to each other to make the accommodation space 13 airtight.

[0059] More specifically, the setting of the locking portion 41 on the sheath 2 locks the applicator 1 to the tube body 32. The sheath 2 presses the first groove 11 and / or the second groove 12, and the abutting portion 42 of the first groove 11 is closely attached to the abutting portion 42 of the second groove 12, thereby achieving a tight connection effect among the first groove 11 abutting against the second groove 12 and the second groove 12 abutting against the tube body 32, solving the problem of poor connection stability between the applicator 1 and the tube body 32, and being prone to displacement or detachment during the application process;

[0060] When the applicator 1 is locked to the tube body 32, the tube body 32 abuts against the second groove 12. Further, relative movement is not likely to occur between the first groove 11 and the second groove 12, and relative movement is not likely to occur between the second groove 12 and the tube body 32; thereby maintaining the stability of the connection between the first groove 11 and the second groove 12, achieving the tightness of the accommodation space 13, making the refrigerant not easily leak, helping to solve the problem of refrigerant leakage of the applicator 1, and ensuring the use safety of users.

[0061] Further, as Figure 1 , Figure 4 , Figure 5 , Figure 7 , Figure 9 and Figure 10 shown, a ring-shaped protrusion 111 extends outward from the outer side wall 82 of one of the first groove 11 and the second groove 12, and a ring-shaped groove 121 matching the ring-shaped protrusion 111 is formed by inward depression on the outer side wall 82 of the other;

[0062] The ring-shaped protrusion 111 is used to be embedded in the ring-shaped groove 121 to achieve the snap connection between the first groove 11 and the second groove 12.

[0063] In some embodiments of the present application, as Figure 1 and Figure 7 shown, a ring-shaped protrusion 111 extends outward from the outer side wall 82 of the first groove 11, and a ring-shaped groove 121 matching the ring-shaped protrusion 111 is formed by inward depression on the outer side wall 82 of the second groove 12;

[0064] In other embodiments of the present application, as Figure 7 and Figure 10 shown, a ring-shaped protrusion 111 extends outward from the outer side wall 82 of the second groove 12, and a ring-shaped groove 121 matching the ring-shaped protrusion 111 is formed by inward depression on the outer side wall 82 of the first groove 11.

[0065] When the annular protrusion 111 is inserted into the annular groove 121, a relatively stable connection relationship will be formed, restricting the relative movement of the first groove body 11 and the second groove body 12 in the radial direction, which helps to avoid accidental loosening or detachment to a certain extent during use. The application process is mostly the movement of the applicator 1 in the radial direction, which can meet the actual use requirements of the application;

[0066] Although the connection between the annular protrusion 111 and the annular groove 121 is relatively stable, it still belongs to a detachable connection, which can realize the combination and separation of the first groove body 11 and the second groove body 12, and is also convenient for the taking and placing of the refrigerant.

[0067] The snap connection can also disperse the stress at the connection point, reduce wear and damage, thereby extending the service life of the product. The design of the annular protrusion 111 and the annular groove 121 also enables the components to be accurately aligned when connected, maintaining the stability and consistency of performance.

[0068] Furthermore, as Figure 1 shown, the sleeve 2 is provided with a socket part 21 for connecting the first groove body 11. After the sleeve 2 is sleeved on the first groove body 11 and connected to the pipe body 32, the socket part 21 is used to apply a fastening force to the first groove body 11 and / or the second groove body 12, so that the first groove body 11 and the second groove body 12 are tightly connected.

[0069] The application of the fastening force of the socket part 21 of the sleeve 2 helps, on the one hand, the sleeve 2 to be stably connected to the first groove body 11, and on the other hand, it also plays a role in restraining the first groove body 11 and the second groove body 12, making the connection between the first groove body 11 and the second groove body 12 more firm, and further avoiding loosening or displacement of the first groove body 11 and the second groove body 12 during use; at the same time, the application of the fastening force also helps to disperse the stress at the connection, extend the service life, and avoid damage caused by stress concentration.

[0070] Furthermore, due to the application of the fastening force of the socket part 21 of the sleeve 2, the connection between the first groove body 11 and the second groove body 12 becomes tighter, and the acting force in the radial direction of the first groove body 11 and the second groove body 12 is restricted. Also, due to the acting force between the locking part 41 and the abutting surface 42, the acting force in the axial direction of the first groove body 11 and the second groove body 12 is restricted. Furthermore, with the joint cooperation of the locking part 41, the abutting surface 42 and the socket part 21, it is beneficial to enhance the sealing performance of the accommodating space 13, so that the refrigerant in the accommodating space 13 will not overflow from the connection.

[0071] In addition, the design of the socket part 21 makes it easier and faster to install the sleeve 2 onto the first groove body 11, reducing the assembly time and complexity, and optimizing the user's use process.

[0072] Preferably, the sheath 2 is made of an elastic material to achieve a better effect of fastening force constraint.

[0073] Furthermore, as Figure 1 shown in Figure 6 , it further includes a sealing cover 31;

[0074] An outlet nozzle 321 is provided with an outlet 322, and the sealing cover 31 is provided with a sealing post 311;

[0075] The outlet nozzle 321 passes through the first through hole 14 so that the sealing post 311 is embedded in the outlet 322 to achieve the sealed connection between the pipe body 32 and the sealing cover 31.

[0076] Specifically, in some embodiments of the present application, the sealing cover 31 is detachably connected to the pipe body 32. The pipe body 32 is provided with a first connection position 51 and a second connection position 52. The first connection position 51 is used to connect the sealing cover 31, and the second connection position 52 is used to connect the sheath 2. And the outer diameter of the first connection position 51 is not less than the outer diameter of the second connection position 52;

[0077] The embedding of the sealing post 311 into the outlet 322 can effectively prevent the liquid from leaking from the outlet 322 or the connection part, and can maintain the sealing performance of the container itself to a certain extent; and the embedding of the sealing post 311 provides a stable connection point, which can prevent the relative movement or loosening between the pipe body 32 and the sealing cover 31 to a certain extent, and realizes the stability and reliability of the connection;

[0078] The above structural design also simplifies the connection process between the pipe body 32 and the sealing cover 31, makes the assembly more efficient and convenient, and reduces the possible installation errors or operation mistakes.

[0079] Furthermore, as Figure 7 shown in Figure 10 , a stop portion 61 is provided on the inner side wall body 81 of the first groove body 11, and a guiding portion 62 is provided on the inner side wall body 81 of the second groove body 12;

[0080] The guiding portion 62 and the stop portion 61 are used to guide the precise connection between the first groove body 11 and the second groove body 12, and a buffer zone 63 is provided between the stop portion 61 and the guiding portion 62.

[0081] The stop portion 61 is located on the inner side wall body 81 of the first groove body 11, which can stop or limit the movement or position of the second groove body 12 during the connection process, so that the second groove body 12 stops at the correct position for precise docking with the first groove body 11.

[0082] The guiding part 62 is located on the inner side wall 81 of the second groove body 12 and can guide the second groove body 12 to move in the correct direction during the connection process. The geometric shape of the guiding part 62 corresponds to that of the stop part 61, that is, an inclined surface is provided to ensure accurate alignment.

[0083] The buffer zone 63 is located between the stop part 61 and the guiding part 62 and is used to provide a certain buffer between the first groove body 11 and the second groove body 12, which can reduce the damage caused by possible impacts during the connection process.

[0084] The designs of the stop part 61 and the guiding part 62 enable the first groove body 11 and the second groove body 12 to be accurately aligned and positioned during connection, thus ensuring the accuracy of the connection relationship and enhancing the stability and durability of the overall structure.

[0085] Furthermore, the centers of the liquid outlet nozzle 321, the liquid outlet 322, the first through hole 14, the sheath 2, and the sealing column 311 are coaxially arranged.

[0086] The coaxial arrangement of the centers of the liquid outlet nozzle 321, the liquid outlet 322, the first through hole 14, the sheath 2, and the sealing column 311 helps to achieve accurate alignment of all components during assembly, reduce errors and friction during the assembly process, and thus improve the assembly efficiency and quality.

[0087] The coaxial arrangement also helps to optimize the sealing effect. When the central axes of the liquid outlet nozzle 321, the liquid outlet 322, the first through hole 14, the sheath 2, and the sealing column 311 are aligned, the sealing column 311 can uniformly apply pressure to the liquid outlet 322 to form an effective seal at the liquid outlet 322 and prevent liquid leakage.

[0088] The coaxial design can also effectively share the mechanical stress generated during assembly and use, help to avoid component damage or structural deformation caused by non - coaxial installation to a certain extent, and improve the structural stability and durability of the container.

[0089] Furthermore, the applicator 1 narrows in the direction away from the tube body 32, and the cross - sectional shape of the applicator 1 includes a U - shape.

[0090] The U - shaped cross - section makes the side of the applicator 1 away from the tube body 32 narrower. This morphological design can provide more precise coating control. It is effectively defined between the two side edges of the U - shaped applicator 1, making the distribution of the skin care product on the surface of the applicator 1 more uniform and controllable, which helps the user's application control during actual use.

[0091] The U - shaped cross - section design can also minimize the waste of the skin care product. The narrowing of the end of the applicator 1 can precisely control the flow of the skin care product and avoid excessive coating or overflow.

[0092] The applicator 1 with a U-shaped cross-section is designed to fit the shape and curvature of the facial surface and contour, and can be coated along the facial surface to achieve a relatively good skin contact effect, optimize the touch feeling between the applicator 1 and the face when the user uses the applicator 1 for application, and further optimize the user's application experience.

[0093] Furthermore, in some embodiments of the present application, the annular groove 121 gradually narrows in the concave direction, and the annular protrusion 111 gradually narrows in the extending direction;

[0094] The gradually narrowing design of the annular groove 121 and the annular protrusion 121 can improve the tightness and fitting accuracy between the first groove body 11 and the second groove body 12, and to a certain extent, prevent the first groove body 11 and the second groove body 12 from loosening or having a small displacement during work, thereby enhancing the overall connection strength and stability.

[0095] Furthermore, the refrigerant includes a liquid refrigerant.

[0096] The liquid refrigerant has high thermal conductivity, can effectively absorb and release heat in the refrigeration cycle, can quickly and efficiently adjust the temperature, has strong refrigeration capacity, and optimizes the cold compress effect of the applicator 1; and the refrigerant in the form of a fluid can be quickly frozen and solidified under specific conditions.

[0097] Exemplarily, the liquid refrigerant can be water, can also be medical alcohol, or can also be propylene glycol. Of course, no specific limitation is made on the specific material of the refrigerant.

[0098] Specifically, as Figure 9 with Figure 10 shown, in some other embodiments of the present application, the first groove body 11 and the sheath 2 are integrally formed.

[0099] The integral formation of the sheath 2 and the first groove body 11 can provide an additional protective layer to prevent the first groove body 11 from being physically damaged or eroded by the environment, thereby enhancing the overall mechanical strength and durability; the sheath 2 can effectively block external substances such as moisture and dust from entering the interior of the first groove body 11 and maintain the stability and reliability of its function.

[0100] Furthermore, as Figure 8 with Figure 9 shown, an internal thread 71 is provided on the locking portion 41, and an external thread 72 is provided on the tube body 32; the applicator 2 is screwed onto the external thread 72 through the internal thread 71.

[0101] More specifically, internal threads 71 are provided on both the locking part 41 and the inner wall of the sealing cover 31, and external threads 72 are provided on both the first connection position 51 and the second connection position 52; the sealing cover 31 is screwed onto the first connection position 51 through the internal thread 71, and the applicator 1 is screwed onto the second connection position 52 through the internal thread 71 on the locking part 41.

[0102] The connection of the internal thread 71 and the external thread 72 provides a reliable connection method, enabling the sealing cover 31 and the applicator 1 to be firmly connected to the first connection position 51 and the second connection position 52, and being able to strongly resist the influence of vibration and external forces.

[0103] The connection of the internal thread 71 and the external thread 72 makes the installation and disassembly of the sealing cover 31 and the applicator 1 more convenient. When the sealing cover 31 and the applicator 1 are tightly screwed together through the internal thread 71, a relatively good sealing effect is formed, which helps to prevent the leakage of liquid.

[0104] Furthermore, an outer side wall body 82 of the first groove body 11 further extends outward with a reinforcing part (not shown in the figure) for strengthening the connection strength between the first groove body 11 and the second groove body 12.

[0105] The reinforcing part can effectively increase the structural stability and rigidity of the first groove body 11 at the connection, can better withstand external forces and vibrations, and can reduce the risk of deformation and loosening at the connection.

[0106] The reinforcing part can clamp or engage with the second groove body 12 by cooperating with the annular protrusion 111, making the connection point more firm and reliable.

[0107] The embodiments of the present application at least have the following beneficial effects:

[0108] The embodiments of the present application provide an application device with relatively good use flexibility, which can achieve detachable connection with the tube body, is convenient for cooling the applicator alone without affecting the drugs such as skin care products stored inside the tube body, and optimizes the user experience. The sealing performance of the accommodation space 13 for accommodating the refrigerant in the applicator 1 is relatively good; specifically, the applicator 1 is locked to the tube body 32 through the locking part 41.
