DETAILED DESCRIPTION

[0025] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0026] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0027] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0028] See also Figure 1-Figure 9 In the embodiment of the utility model, a head-locking spring double-chamber pump includes a pump body 7 and a pressing structure that cooperates with the pump body 7 to realize pumping, and also includes a storage barrel 4, the pump body 7 is inserted into the storage barrel 4 and can be sealed and movable relative to the storage barrel 4, and a sealing member 6 connected to the pump body 7 is arranged on the inner side of one end of the storage barrel 4 away from the insertion direction of the pump body 7, and a storage space is formed between the storage barrel 4 and the pump body 7; a threaded cover 3 is connected to the storage barrel 4, and a cover body 2 is clamped on the threaded cover 3 and a plurality of spiral grooves 12 are formed on the inner side thereof, and limit positions are formed at both ends of the spiral grooves 12, and a movable part is formed at the end of the pump body 7, and the movable part can rotate along the spiral groove 12, and enable the pump body 7 to drive the sealing member 6 to move, so as to conduct the storage space.

[0029] In this embodiment, when not in use, the movable part on the pump body 7 is in the restricted position at the end of the spiral groove 12 away from the storage barrel 4, so that the pump body 7 will not be relatively displaced with respect to the storage barrel 4, ensuring that the blocking member 6 will not be accidentally opened due to impact, and the stability is strong, ensuring that the material in the storage barrel 4 will not fall out when not in use. At the same time, when the movable part on the pump body 7 is in the restricted position at the end of the spiral groove 12 close to the storage barrel 4, the blocking member 6 will not reset and block the storage barrel 4 again, preventing the double-chamber pump from being directly reused after being recovered, eliminating the risk of being directly applied, and having a strong anti-counterfeiting function.

[0030] For further information, see Figure 7 A horizontal groove 1201 and a vertical groove 1202 are respectively formed at both ends of the spiral groove 12, and a protruding block 1203 is formed at the connection between the spiral groove 12 and the horizontal groove 1201 and the vertical groove 1202. The horizontal groove 1201 and the vertical groove 1202 cooperate with the protruding block 1203 to form a limiting position.

[0031] When the double-chamber pump is not in use, the movable part is in the horizontal groove 1201 and is limited by the protruding block 1203. When it is needed, the pressing structure is manually rotated to drive the pump body 7 to rotate relative to the storage barrel 4, thereby driving the movable part to move out of the horizontal groove 1201 and move along the spiral groove 12 to the vertical groove 1202, and is limited by the protruding block 1203 at the vertical groove 1202 to ensure that the pump body 7 cannot rotate in the opposite direction.

[0032] See also Figure 2 and Figure 3 The movable part includes an extension ring 8 fixed to the pump body 7, and a limiting movable block 9 that movably cooperates with the spiral groove 12 is provided at the outer circle of the extension ring 8. The limiting movable block 9 moves from the horizontal groove 1201 along the spiral groove 12 to the vertical groove 1202, and the pump body 7 drives the blocking part 6 to make the storage space conductive.

[0033] Furthermore, an annular member 11 is provided on the inner side of the cover body 2, the spiral groove 12 is formed on the inner wall of the annular member 11, and an annular groove for plugging into the threaded cover 3 is formed between the outer side of the annular member 11 and the cover body 2, wherein a plurality of second buckle lines 14 are formed on the inner wall of the cover body 2, and a plurality of fourth buckle lines 17 are formed on the threaded cover 3, and when the threaded cover 3 is plugged into the cover body 2, the second buckle lines 14 and the fourth buckle lines 17 are alternately placed.

[0034] In this embodiment, the connection mode between the cover body 2 and the threaded cover 3 is set to be a buckle line connection, which can effectively improve the convenience of assembly production and facilitate installation while achieving sealing.

[0035] It should be noted that at least two limit blocks 18 are formed on the threaded cover 3, and a limit groove 16 is formed in the annular groove, which is sealed and slidably matched with the limit block 18, so that after the cover body 2 and the threaded cover 3 are connected by buckle wire, the cover body 2 will not rotate relative to the threaded cover 3, thereby improving the stability of the connection between the cover body 2 and the threaded cover 3.

[0036] For further information, see Figure 2-Figure 4 The pressing structure includes a pump sleeve 13 inserted into the pump body 7 and plugged into the end of the pump body 7, a column 19 penetrating the pump sleeve 13 and extending into the pump body 7, a piston 5 is installed at one end of the column 19, and the other end is detachably connected to the pressing head 1 penetrating the cover body 2; it also includes a spring 22, the spring 22 is located in the pump sleeve 13 and is sleeved on the outside of the column 19, and the two ends of the spring 22 are respectively in contact with the column 19 and the pump sleeve 13.

[0037] It should be noted that the pressing head 1 includes a liquid outlet end and a connecting pipe integrally formed with the liquid outlet end. The connecting pipe is sealed and clamped with the column 19, and can drive the column 19 to rotate when the pressing head 1 rotates.

[0038] A first buckle line 10 is formed at one end of the pump body 7 described above, and an embedded slot for inserting the end of the pump body 7 is formed on the pump sleeve 13, and a third buckle line 15 buckled with the first buckle line 10 is formed in the embedded slot. A limiting tooth is also provided at the inner end of the pump body 7, and a limiting tooth engaged with the limiting tooth is provided on the outer wall of the pump sleeve 13. When the pump sleeve 13 is inserted into the pump body 7, the limiting tooth cooperates with the limiting tooth to ensure that the pump sleeve 13 will not rotate relative to the pump body 7 (that is, when the pump sleeve 13 rotates, it can drive the pump body 7 to rotate). At the same time, the first buckle line 10 and the third buckle line 15 cooperate to realize the axial limitation of the pump sleeve 13 relative to the pump body 7, and maintain the sealing of the pump sleeve 13 after being connected to the pump body 7.

[0039] Furthermore, a limiting ring 23 is also fastened to one end of the pump sleeve 13 away from the pump body 7, and the diameter of the through hole on the limiting ring 23 for the pressing head 1 to pass through is smaller than the outer diameter of the column 19 toward the pressing head 1, wherein the connection method of the limiting ring 23 and the pump sleeve 13 is equivalent to the connection method of the pump sleeve 13 and the pump body 7, and therefore, this embodiment will not elaborate on this.

[0040] An external thread 20 is formed on the column 19 located in the pump sleeve 13, and an internal thread 21 threadedly connected to the external thread 20 is formed on the inner side of the pump sleeve 13. When the double-chamber pump is not in use, the column 19 and the pump sleeve 13 are in a threaded connection state, and the spring 22 is in a compressed state. When in use, the pressing head 1 is rotated to drive the column 19 to rotate, so that the external thread 20 and the internal thread 21 are disengaged from the threaded connection state, and the spring 22 is released, but the spring 22 is still in a certain compression state. At this time, the pressing head 1 can drive the column 19 to move axially relative to the pump sleeve 13, and the spring 22 provides a reset force.
