[0030] Embodiment 1:

[0031] Please refer to Figures 1-5 The above technical solutions are described in detail by the following embodiments of the utility model:

[0032] A pressing type air cushion stick comprises:

[0033] The application discloses a material dispensing device.

[0034] The material dispensing device comprises a dispensing pipe 13 and an end cover 12 which are integrally formed by plastic material, and the dispensing pipe 13 is connected with the sponge 15.

[0035] The dispensing pipe 13 is provided with a plurality of dispensing holes 14 on the top side.

[0036] The dispensing pipe 13 is sealed on the top end, and the material can enter the dispensing pipe 13 from the dispensing holes 14 and then enter the sponge 15, so as to be applied by a user.

[0037] The end cover 12 is provided with a protective cover 11.

[0038] The protective cover 11 is integrally formed by plastic material, and the protective cover 11 is used for protecting the sponge 15.

[0039] The material dispensing device comprises a dispensing pipe 13 and an end cover 12 which are integrally formed by plastic material, and the dispensing pipe 13 is connected with the sponge 15.

[0040] The dispensing pipe 13 is provided with a plurality of dispensing holes 14 on the top side.

[0041] The material dispensing device comprises a dispensing pipe 13 and an end cover 12 which are integrally formed by plastic material, and the dispensing pipe 13 is connected with the sponge 15.

[0042] The protective cover 21 is integrally formed by plastic material, and the protective cover 21 is used for protecting the material pipe 22.

[0043] The material pipe 22 is provided with an extrusion ring 25 which is in abutment with the edge of the diaphragm spring 16, and the extrusion ring 25 is provided with a plurality of first guide blocks 26 which are in sliding connection with the second guide grooves 213.

[0044] The extrusion ring 25, the first guide block 26 and the material pipe 22 are integrally formed by plastic material. Since the first guide block 26 is in sliding connection with the second guide groove 213, the material pipe 22 will not rotate when sliding downward.

[0045] When the material pipe 22 is subjected to external force greater than the elastic force of the diaphragm spring 16, the material pipe 22 will slide downward, thereby driving the extrusion ring 25 to slide downward, further extruding the diaphragm spring 16, and the diaphragm spring 16 deforms. Meanwhile, the discharge pipe 13 extends into the material pipe 22, and the discharge hole 14 is in contact with the material in the material pipe 22. The high-pressure material in the material pipe 22 will be discharged from the discharge hole 14.

[0046] The pressurizing assembly 3 comprises a one-way valve 37 connected with the sealing cover 24, a pressurizing cylinder 35 connected at the top of the one-way valve 37, a pressurizing piston 34 slidingly installed in the pressurizing cylinder 35, and a pressing assembly connected at the top of the pressurizing piston 34, the pressing assembly being used to drive the pressurizing piston 34 to reciprocate, inject air into the material pipe 22 through the one-way valve 37, and the pressurizing cylinder 35 being externally provided with a second limiting block 36 for limiting the pressing depth of the pressing assembly.

[0047] The air outlet of the one-way valve 37 is clamped at the top of the sealing cover 24, and the air inlet of the one-way valve 37 is clamped at the bottom of the pressurizing cylinder 35, so as to ensure that the air flow can only flow from the pressurizing cylinder 35 to the sealing cover 24.

[0048] When the pressurizing piston 34 moves downward, the air can be pressed from the pressurizing cylinder 35 into the one-way valve 37, and finally into the material pipe 22 from the sealing cover 24.

[0049] When the pressurizing piston 34 moves upward, due to the presence of the one-way valve 37, the air enters the pressurizing cylinder 35 from above the pressurizing piston 34.

[0050] The movement stroke of the pressurizing piston 34 determines the amount of air entering the material pipe 22 from the sealing cover 24.

[0051] The pressing assembly comprises a pressing cover 31, the pressurizing piston 34 being clamped and installed at the center inside the pressing cover 31, a plurality of limiting protrusions 32 being provided at the middle of the outer side of the pressing cover 31, the limiting protrusions 32 being in sliding connection with the first guide groove 212, and the bottom surface of the pressing cover 31 being in contact with the top surface of the first limiting block 214.

[0052] The pressing cover 31 is made of plastic material. The limiting protrusions 32 are in sliding connection with the first guide groove 212, which can prevent the pressing cover 31 from being separated from the protective shell 21. The limiting protrusions 32 are eight in total, and the number of the limiting protrusions 32 is the same as that of the first guide groove 212.

[0053] Since the pressing cap 31 and the protective shell 21 are both made of plastic material, they have certain elasticity. When the pressing cap 31 is rotated, the limiting protrusion 32 is rotated from one first guide slot 212 to the adjacent another first guide slot 212, and the rotation angle is 45°, and vibration is generated at the same time, thereby reminding the operator of the rotation angle.

[0054] The pressing cap 31 is rotated, and the bottom surface of the pressing cap 31 is separated from the first limiting block 214, so that the pressing cap 31 can be moved downward.

[0055] The pressing cap 31 is provided with a limiting sleeve 33, the limiting sleeve 33 is in sliding connection with the pressing cylinder 35, the edge of the limiting sleeve 33 is in a stepped shape, and the top surface of the second limiting block 36 is in contact with the bottom surface of the limiting sleeve 33.

[0056] The limiting sleeve 33 and the pressing cap 31 are integrally formed by using plastic material. The second limiting block 36 is in an L shape. The second limiting block 36 limits the rotation direction and the downward movement stroke of the limiting sleeve 33.

[0057] The rotation of the pressing cap 31 can drive the rotation of the limiting sleeve 33. After the limiting sleeve 33 is rotated by 45°, the limiting sleeve 33 is separated from the second limiting block 36. The distance that the limiting sleeve 33 can be moved downward is increased by 1 / 3 of the maximum distance that the limiting sleeve 33 can be moved downward each time the limiting sleeve 33 is rotated by 45°. The limiting sleeve 33 is rotated by a maximum of 135°.

[0058] The limiting sleeve 33 and the pressing cap 31 are clamped with a return spring 38, the bottom surface of the return spring 38 is in abutment with the top surface of the sealing cap 24, and the elastic force of the return spring 38 is smaller than that of the diaphragm spring 16.

[0059] The pressing cap 31 is rotated, the pressing cap 31 is separated from the first guide block 26, and the limiting sleeve 33 is separated from the second limiting block 36 at the same time. Then a downward pressure is applied to the pressing cap 31. The pressing cap 31 can drive the limiting sleeve 33 to slide downward, and can drive the pressing piston 34 to slide downward and compress the return spring 38.

[0060] Until the limiting sleeve 33 is in contact with the second limiting block 36 again, at which time the pressing piston 34 stops moving, but the material pipe 22 slides downward, the diaphragm spring 16 is compressed, and the discharge pipe 13 extends into the material pipe 22.

[0061] The pressure applied to the pressing cap 31 is removed. The diaphragm spring 16 drives the material pipe 22 to move upward first, and then the return spring 38 drives the pressing cap 31 and the limiting sleeve 33 to move upward.

[0062] When the operator uses the device, the pressing cap 31 is rotated, the pressing cap 31 is separated from the first guide block 26, and the limiting sleeve 33 is separated from the second limiting block 36 at the same time.

[0063] When a downward pressure is applied to the pressing cap 31, the pressing cap 31 can drive the limiting sleeve 33 to slide downward, and can drive the pressing piston 34 to slide downward and compress the reset spring 38.

[0064] When the pressing piston 34 moves downward, air can be pressed from the pressing cylinder 35 into the one-way valve 37, and finally into the material pipe 22 from the sealing cap 24. At this time, the material pipe 22 is in a high-pressure state.

[0065] Until the limiting sleeve 33 contacts the second limiting block 36 again, at this time, the pressing piston 34 stops moving.

[0066] The pressure continues to increase, and the pressure is transmitted from the limiting sleeve 33 to the second limiting block 36, then to the pressing cylinder 35, then to the sealing cap 24 through the one-way valve 37, and finally to the material pipe 22, at this time, the material pipe 22 slides downward, compresses the diaphragm spring 16, and at the same time, the discharge pipe 13 extends into the material pipe 22.

[0067] The discharge hole 14 contacts the material in the material pipe 22. The high-pressure material in the material pipe 22 is discharged from the discharge hole 14. The discharged material enters the discharge pipe 13, and finally enters the sponging sponge 15.

[0068] When the pressure applied to the pressing cap 31 is removed, the diaphragm spring 16 first drives the material pipe 22 to move upward, and then the reset spring 38 drives the pressing cap 31 and the limiting sleeve 33 to move upward.

[0069] The stroke of the limiting sleeve 33 moving downward determines the stroke of the pressing piston 34, thereby determining the amount of air entering the material pipe 22, and further determining the amount of material discharged from the discharge pipe 13.

[0070] The stroke of the limiting sleeve 33 moving downward is related to the rotation angle of the pressing cap 31. Every 45° rotation, the stroke of the limiting sleeve 33 increases by 1 / 3 of the maximum stroke. Therefore, every 45° rotation of the pressing cap 31, the discharge amount increases by 1 / 3 of the maximum discharge amount.

[0071] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application, and are not intended to limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
