[0026] Reference Figures 1 to 7, a pump with a hidden liquid outlet, comprising:

[0027] A pressing head 1 and a liquid outlet nozzle 2, wherein the pressing head 1 is provided with a linear slide groove 11, and the liquid outlet nozzle 2 is slidably connected to the linear slide groove 11; it also includes a guide cover 4, which is rotatably connected to the pressing head 1, and the guide cover 4 is provided with a spiral guide groove 41, and the liquid outlet nozzle 2 is provided with a guide block 21, and the guide block 21 is slidably connected to the guide groove 41.

[0028] The improvement of the present technology over the prior art is mainly that a liquid outlet nozzle 2 is provided which is slidably connected to the pressing head 1. Figure 2 In the locked state, the push head 1 is rotated, and the liquid outlet nozzle 2 rotates with the push head 1, while the guide cover 4 remains stationary, and the guide block 21 rotates in the guide groove 41. Since the guide groove 41 is spiral, the guide block 21 rotates and translates at the same time. During the translation of the guide block 21, the liquid outlet nozzle 2 extends from the push head 1.

[0029] In a preferred embodiment, a mounting through hole 42 is provided in the guide cover 4, and a sliding sleeve 3 is rotatably connected in the mounting through hole 42. The sliding sleeve 3 is provided with a vertically arranged pop-up groove 31 and an arc-shaped speed reduction strip 33, and a positioning groove is provided on the side of the arc-shaped speed reduction strip 33; a liquid outlet column 14 is provided on the pressing head 1, and the liquid outlet column 14 is L-shaped. The upper part of the liquid outlet column 14 extends into the liquid outlet nozzle 2, and the sliding sleeve 3 is sleeved on the lower part of the liquid outlet column 14. A positioning boss 15 is provided on the outer wall of the liquid outlet column 14; the positioning boss 15 is provided in the positioning groove, and when the pressing head 1 rotates, the positioning boss 15 can pass over the arc-shaped speed reduction strip 33 and disengage from the positioning groove, and the pressing head 1 continues to rotate, and the positioning boss 15 can move to the bottom of the pop-up groove 31 and be slidably connected to the pop-up groove 31 up and down. The sliding sleeve 3 is used to lock the angle of the push head 1 when the pump is not activated. In the locked state, the push head 1 is rotated, and the positioning boss 15 passes over the arc-shaped deceleration strip 33 and disengages from the positioning groove, and the angle of the push head 1 is no longer locked. Figure 3 , the push head 1 is in the unlocked state, the push head 1 continues to rotate, the positioning boss 15 can move to the bottom of the ejection slot 31, the positioning boss 15 moves upward from the ejection slot 31, the push head 1 rises, and then the push head 1 can be pressed down so that it can be used to discharge liquid, such as Figure 3 , press head 1 to enter the pop-up state.

[0030] In a preferred embodiment, the mounting through hole 42 is transitionally matched with the sliding sleeve 3, a first limiting protrusion 32 is provided on the sliding sleeve 3, a second limiting protrusion 43 is provided in the mounting through hole 42, and the first limiting protrusion 32 abuts against the second limiting protrusion 43; the pop-up groove 31 and the arc-shaped speed reduction strip 33 are respectively located on the left and right sides of the first limiting protrusion 32, and the second limiting protrusion 43 and the pop-up groove 31 are located on the same side of the first limiting protrusion 32.

[0031] Since the mounting through hole 42 is in transitional fit with the sliding sleeve 3, when the positioning boss 15 is located in the positioning groove, the sliding sleeve 3 can rotate synchronously with the pressing head 1 for one circle until the first limiting protrusion 32 abuts against the second limiting protrusion 43, and the sliding sleeve 3 cannot continue to rotate, while the pressing head 1 continues to rotate relative to the sliding sleeve 3. When the pressing head 1 rotates for the first circle, the liquid outlet nozzle 2 partially extends out of the pressing head 1, and when the pressing head 1 rotates for the second circle, the liquid outlet nozzle 2 continues to extend outward.

[0032] In a preferred embodiment, a decorative cover 5 is further included, and the decorative cover 5 is covered on the guide cover 4, and the decorative cover 5 is rotatably connected with the guide cover 4. The decorative cover 5 is provided with an avoidance slot 51, and the guide block 21 passes through the avoidance slot 51 and then is inserted into the guide slot 41. During the rotation of the pressing head 1 and the liquid outlet 2, the decorative cover 5 also rotates synchronously until the positioning boss 15 pops out from the ejection slot 31, and the guide block 21 also moves out of the avoidance slot 51 and the guide slot 41. The decorative cover 5 can cover the guide slot 41 to prevent dust from falling into the guide slot 41.

[0033] In a preferred embodiment, the pressing head 1 further comprises a decorative tube 12, which is sleeved outside the liquid outlet 2, and a gap is provided at the bottom of the decorative tube 12 for avoiding the guide block 21, and a spring piece 13 is provided in the gap, and the guide block 21 can be engaged with the spring piece 13. The guide block 21 is engaged with the spring piece 13 after moving outward a certain distance, so as to prevent the liquid outlet 2 from sliding when the user uses the product.

[0034] In a preferred embodiment, it also includes a tooth cover 6, a main column 7, a secondary column 8, a piston 9, a main body 10, and a spring 16; the spring 16 is arranged in the inner cavity of the main body 10, the piston 9 is connected to the inner cavity of the main body 10 by sliding up and down, the secondary column 8 is fixed to the lower part of the main column 7, the piston 9 is sleeved outside the secondary column 8, and a liquid inlet hole 81 is provided on the secondary column 8, the upper end of the piston 9 can abut against the lower end of the main column 7, and the lower end of the piston 9 can abut against the lower part of the secondary column 8, and the spring 16 is used to support the secondary column 8; the guide cover 4 is fixedly connected to the upper end of the main body 10, the tooth cover 6 is fixedly connected to the main body 10, and the tooth cover 6 is arranged on the lower side of the guide cover 4.

[0035] The tooth cover 6 is used to connect the daily chemical product packaging bottle. Figure 4 When the push head 1 pops out, the liquid outlet nozzle 2 extends out, and the push head 1 is pressed, and the main column 7 and the auxiliary column 8 press the spring 16 downward, and then the main column 7 pushes the piston 9 downward, and the liquid in the inner cavity of the body 10 is squeezed, and the liquid enters the auxiliary column 8 from the liquid inlet hole 81 on the auxiliary column 8, and then the liquid enters the main column 7, the liquid outlet column 14 and the liquid outlet nozzle 2 in sequence. During the rebound of the push head 1, negative pressure is generated in the body 10, and the liquid enters the body 10 from the daily chemical product packaging bottle.
