[0018] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0019] Example 1

[0020] See also Figure 1-Figure 4 The present embodiment provides a pressing pump structure, including a bottle cap 1 installed on the bottle mouth, wherein a through hole 10 is formed in the middle of the bottle cap 1. When the bottle cap 1 is installed on the bottle mouth, the through hole 10 is connected to the bottle mouth. The pressing pump structure also includes a pressure head 2 and a top cover 3. A liquid outlet channel is formed inside the pressure head 2. One end of the liquid outlet channel is located at the side of the pressure head 2, and the other end passes through the middle of the bottom of the pressure head 2. The pressure head 2 is connected to a pump tube (not shown in the figure) through the bottom end of the liquid outlet channel. The pump tube is a prior art and is not described in detail in the present embodiment. The pump tube passes through the through hole 10 and extends into the bottle mouth. The liquid outlet pipe 4 is inserted into one end of the liquid outlet channel on the side of the pressure head 2, and the pressure head 2 can be elastically pressed on the bottle cap 1. When the pressure head 2 is pressed, the pump tube extends into the bottle mouth and pumps out the lotion from the liquid outlet pipe 4. The top cover 3 is buckled on the bottle cap 1 and the outside of the pressure head 2. The liquid outlet pipe 4 passes through the side of the top cover 3 and is limited at a certain height of the axis. That is, since the liquid outlet pipe is limited by the top cover 3, the liquid outlet pipe cannot be rotated and can only move up and down. Therefore, when the pressure head 2 is pressed, the direction of the process of pumping out the sunscreen can be controlled, and the use is relatively reasonable and reliable.

[0021] In this embodiment, the pressing pump structure also includes a bottle 5, and a plurality of air permeable grooves 13 are arranged circumferentially on the inner wall of the bottom of the bottle cap 1, so that when the bottle cap 1 is screwed onto the bottle mouth of the bottle 5, there is a gap between the air permeable groove 13 and the outside of the bottle 5. The bottle cap 1 is fastened to the bottle 5, and the air permeable groove 13 is connected to the external air. The bottle cap 1 is not tightly fixed on the bottle 5 and is difficult to rotate and disassemble due to closure. The bottle cap 1 can be removed by rotating it in the opposite direction with a little force.

[0022] Furthermore, a positioning platform 11 is formed on the outer side of the bottle cap 1, and a slot 12 is formed between adjacent positioning platforms 11. The inner wall of the positioning platform 11 is provided with reinforcing ribs, which enhance the structural strength of the positioning platform 11 on the bottle cap 1 and have strong anti-deformation ability.

[0023] Secondly, a clamping block 30 is formed on the inner wall of the top cover 3 along its axial direction. The clamping block 30 is engaged with the clamping groove 12 so that the top cover 3 can be buckled and fixed on the bottle cap 1. Therefore, the top cover 3 is quickly assembled to the bottle cap 1 by plugging. The cooperation between the clamping block 30 and the clamping groove 12 makes it possible for the bottle cap 1 and the top cover 3 to only be plugged in and out and unable to rotate relative to each other.

[0024] As mentioned above, further, the inner wall of the top cover 3 is located at the upper end of the clamping block 30 to form a limiting platform 31. When the top cover 3 is buckled on the bottle cap 1, the limiting platform 31 abuts against the upper end of the positioning platform 11 to perform adaptive limiting.

[0025] In addition, a limiting groove 32 is formed on the side of the top cover 3, and the limiting groove 32 is an oblong shape. The liquid outlet pipe 4 passes through the limiting groove 32. When the pressure head 2 is pressed, the pressure head 2 can only move up and down in the limiting groove 32, and therefore cannot rotate, strictly preventing the pressing effect from being affected by the arbitrary rotation of the pressure head 2.

[0026] Example 2

[0027] A press pump structure includes a bottle cap 1 installed on a bottle mouth, a through hole 10 is formed in the middle of the bottle cap 1, and when the bottle cap 1 is installed on the bottle mouth, the through hole 10 is connected to the bottle mouth, and the press pump structure also includes a pressure head 2 and a top cover 3, a liquid outlet channel is formed inside the pressure head 2, one end of the liquid outlet channel is located at the side of the pressure head 2, and the other end passes through the middle of the bottom of the pressure head 2, and the pressure head 2 is connected to a pump tube (not shown in the figure) through the bottom end of the liquid outlet channel. The pump tube is a prior art and is not described in detail in this embodiment. The pump tube passes through the through hole 10 and extends into the bottle mouth. A liquid outlet pipe 4 is inserted into one end of the liquid outlet channel on the side of the head 2. The pressure head 2 can be elastically pressed on the bottle cap 1. When the pressure head 2 is pressed, the pump tube extends into the bottle mouth and pumps out the lotion from the liquid outlet pipe 4. The top cover 3 is buckled on the bottle cap 1 and the outside of the pressure head 2. The liquid outlet pipe passes through the side of the top cover 3 and is limited at a certain height of the axis. That is, since the liquid outlet pipe is limited by the top cover 3, the liquid outlet pipe cannot be rotated and can only move up and down. Therefore, when the pressure head 2 is pressed, the direction of the process of pumping out the sunscreen can be controlled, and the use is relatively reasonable and reliable.

[0028] In this embodiment, the pressing pump structure also includes a bottle 5, and a plurality of air permeable grooves 13 are arranged circumferentially on the inner wall of the bottom of the bottle cap 1, so that when the bottle cap 1 is screwed onto the bottle mouth of the bottle 5, there is a gap between the air permeable groove 13 and the outside of the bottle 5. The bottle cap 1 is fastened to the bottle 5, and the air permeable groove 13 is connected to the external air. The bottle cap 1 is not tightly fixed on the bottle 5 and is difficult to rotate and disassemble due to closure. The bottle cap 1 can be removed by rotating it in the opposite direction with a little force.

[0029] Furthermore, a positioning platform 11 is formed on the outer side of the bottle cap 1, and a slot 12 is formed between adjacent positioning platforms 11. The inner wall of the positioning platform 11 is provided with reinforcing ribs, which enhance the structural strength of the positioning platform 11 on the bottle cap 1 and have strong anti-deformation ability.

[0030] Secondly, a clamping block 30 is formed on the inner wall of the top cover 3 along its axial direction. The clamping block 30 is engaged with the clamping groove 12 so that the top cover 3 can be buckled and fixed on the bottle cap 1. Therefore, the top cover 3 is quickly assembled to the bottle cap 1 by plugging. The cooperation between the clamping block 30 and the clamping groove 12 makes it possible for the bottle cap 1 and the top cover 3 to only be plugged in and out and unable to rotate relative to each other.

[0031] As mentioned above, further, the inner wall of the top cover 3 is located at the upper end of the clamping block 30 to form a limiting platform 31. When the top cover 3 is buckled on the bottle cap 1, the limiting platform 31 abuts against the upper end of the positioning platform 11 to perform adaptive limiting.

[0032] In addition, a limiting groove 32 is formed on the side of the top cover 3, and the limiting groove 32 is an oblong shape. The liquid outlet pipe 4 passes through the limiting groove 32. When the pressure head 2 is pressed, the pressure head 2 can only move up and down in the limiting groove 32, and therefore cannot rotate, strictly preventing the pressing effect from being affected by the arbitrary rotation of the pressure head 2.

[0033] In this embodiment, an avoidance groove 33 is formed on the top cover 3 on the side facing away from the limiting groove 32, through which fingers can be inserted to the upper end of the pressure head 2, and a handle 34 is formed on the upper end of the top cover 3 for easy grasping. The pressure head 2 can be pressed by fingers from the avoidance groove 33 without removing the cover, which is easy to operate.

[0034] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
