[0041] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0042] Embodiment 1

[0043] like Figure 1-Figure 3 As shown, it comprises a cover 1, and a groove is formed at the bottom of the cover 1 and a connecting column 11 is arranged in the groove, and the connecting column 11 is used to connect with the pump core 5. The pump core 5 is an existing one that can be purchased directly, so the specific structure is not described in detail here.

[0044] At the same time, a nozzle 12 is opened on one side of the cover 1, and a channel 13 and a channel 2 14 are arranged inside the cover 1, wherein the channel 2 14 is used to connect the channel 13 and the pump core 5, and the channel 13 is connected with the nozzle 12, and a plug 2 is built into the channel 13, and one end of the plug 2 is located at the nozzle 12 and is used to isolate the channel 1 13 from the outside, and an elastic member 3 is arranged between the plug 2 and the channel 1 13.

[0045] Therefore, in actual use, when the user presses the cover 1, the material body applies force to the plug 2 to move the plug 2 and thus allow the material body to come out. After the material body comes out, the plug 2 is reset due to the elastic member 3 and isolates the channel 13 from the outside.

[0046] Therefore, the utility model isolates the built-in material body from the outside air by setting the plug 2, thereby preventing the outside air from contacting the built-in material body, thereby preventing the high-end active ingredients from becoming ineffective after long-term storage.

[0047] The elastic member 3 is a spring, and is located between the plug 2 and the channel 13. The spring installation structure is as follows: first, the plug 2 is provided with a connecting portion 22, and the spring is sleeved outside the connecting portion 22.

[0048] like Figure 2-Figure 3 As shown, the gag 2 is a column, and the gag 2 enters from the nozzle 12. Therefore, in order to make the nozzle 12 larger than the gag 2, a seal 4 is provided between the gag 2 and the nozzle 12. The seal 4 is a column with a hole in the middle, and one end of the gag 2 is located in the seal 4.

[0049] Therefore, in actual use, the sealing member 4 limits the position of the plug 2, and also prevents the material from coming out from other places. In actual use, the material applies force to the plug 2 to move the plug 2, and the material flows out from between the sealing member 4 and the plug 2.

[0050] Moreover, a convex strip 1 41 is arranged on the outer side of the sealing member 4, and a slope 3 is arranged near the nozzle 12 of the convex strip 1 41, and a slope 4 is formed on the nozzle 12 corresponding to the slope 3, thereby increasing the contact area and achieving better sealing.

[0051] At the same time, a second convex strip 42 is arranged on the outer side of the sealing member 4, and the second convex strip 42 is in interference fit with the inner wall of the nozzle 12, so that the sealing member 4 can be installed and limited.

[0052] And there is an inclined contact between the sealing member 4 and the end of the plug 2.

[0053] Embodiment 2, as Figure 4-Figure 5 As shown, this embodiment is basically the same as the first embodiment, the difference being that the mouthpiece 2 itself has elasticity without the elastic member 3, and the mouthpiece 2 is a rod made of an elastic material.

[0054] Therefore, in actual use, when the user presses the cover 1, the material body applies force to the plug 2 to deform the plug 2 so as to allow the material body to flow out, and the plug 2 recovers after the material body flows out and isolates the channel 13 from the outside.

[0055] Embodiment 3: This embodiment is basically the same as Embodiment 1, except that the elastic member 3 and the plug 2 are integrally formed, that is, the elastic member 3 is a plastic spring and is integrally formed with the plug 2.

[0056] Embodiment 4: This embodiment is basically the same as embodiment 1, except that the cover 1 is provided with an opening 15 at one end of the channel 13 away from the nozzle 12, and the nozzle 2 enters into the channel 13 from the opening 15, so the nozzle 2 is not installed by entering from the nozzle 12 but by entering from the opening 15, so there is no need for a seal 4.

[0057] The corresponding structure of the mouthpiece 2 is as follows: first, the mouthpiece 2 comprises a cover plate 23 and a rod portion 24 , and the cover plate 23 is located in the opening 15 and is injection molded with the rod portion 24 .

[0058] Moreover, the injection molding here is two-color injection molding, and the structure between the cover plate 23 and the rod portion 24 is as follows: first, the cover plate 23 is provided with a clamping portion 231 on the side in contact with the rod portion 24 , and the rod portion 24 is provided with a groove corresponding to the clamping portion 231 .

[0059] There is a limiting structure between the cover plate 23 and the opening 15 to prevent the nozzle 2 from falling off the cover 1. The specific structure is as follows: first, a convex strip 3 232 is provided on the outer side of the cover plate 23, and a convex strip 4 is provided on the inner wall of the opening 15, and the convex strip 4 is located on the outer side of the convex strip 3 232 to play a limiting role.

[0060] At the same time, since there is no sealing member 4, the end of the nozzle 2 is in direct contact with the nozzle 12. At this time, one end of the nozzle 2 is located in the nozzle 12 and is formed with a first slope, and the nozzle 12 is formed with a second slope corresponding to the first slope.

[0061] Therefore, in actual use, the setting of the inclined surface can play a certain guiding role.

[0062] Embodiment 5. This embodiment is basically the same as embodiment 1, except that the cover 1 includes an upper cover 16 and a lower cover 17 which are connected to each other, and the bottom of the lower cover 17 is grooved and a connecting column 11 is arranged in the groove, and the lower cover 17 is provided with the nozzle 12, channel one 13 and channel two 14.

[0063] Moreover, the lower cover 17 is provided with an opening 15 at one end of the channel 13 away from the nozzle 12, and the nozzle 2 enters the channel 13 from the opening 15. Therefore, the nozzle 2 is not installed by entering from the nozzle 12, but from the opening 15, so there is no need for the seal 4.

[0064] And the structure corresponding to the nozzle 2 is: first, the nozzle 2 includes a cover plate 23 and a rod portion 24, and the cover plate 23 and the rod portion 24 are integrally formed, and the nozzle 2 is grooved at one end away from the nozzle 12, and a convex strip 5 152 is provided inside the opening 15, and the cover plate 23 is provided with a snap-in groove 233 corresponding to the convex strip 5 152, so that connection and limiting are achieved by adapting the convex strip 5 152 and the snap-in groove 233.

[0065] Meanwhile, other detailed structures are as follows: firstly, the contact surface between the upper cover 16 and the lower cover 17 is an inclined surface, so as to facilitate the installation of the nozzle 2.

[0066] Moreover, the structures between the upper cover 16 and the lower cover 17 are various. The inner wall of the upper cover 16 may be provided with a protrusion 161, and the lower cover 17 may be provided with a slot 171 corresponding to the protrusion 161, so that the connection and limiting are achieved by matching the protrusion 161 and the slot 171.

[0067] Alternatively, the lower cover 17 is provided with a boss 172 on a side in contact with the upper cover 16 , and the upper cover 16 is provided with a connecting groove 162 corresponding to the protrusion 161 , so that connection and limiting are achieved by matching the boss 172 and the connecting groove 162 .

[0068] Or maybe both.

[0069] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. At the same time, the utility model is not limited by the above embodiments, so without departing from the principle and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model claimed for protection.
