[0037] Reference Figures 1 to 12 One embodiment of the utility model provides a pressing pump, which includes a bottle body 100, a screw thread 110, a pump body 130, a main column 140 and a pressing head. The bottle body 100 has a receiving cavity 103 and a bottle mouth 101 connected to the receiving cavity 103. The screw thread 110 is installed on the bottle mouth 101 and is threadedly connected to the outer peripheral wall of the bottle mouth 101. The screw thread 110 is connected to a locking cover 120. The pump body 130 is penetrated by the screw thread 110, and the upper end of the pump body 130 is connected to the locking cover 120. The main column 140 is arranged inside the pump body 130, and the upper end of the main column 140 is penetrated by the locking cover 120. The pressing head includes a mounting portion 150 and a pressing portion 160 which are independent of each other. One end of the mounting portion 150 is threadedly connected to the lock cover 120, and the other end is plugged into the pressing portion 160. The mounting portion 150 is provided with a mounting channel 151 which is plugged into the main column 140. The pressing portion 160 has a liquid outlet channel 162 and a liquid outlet nozzle 161 extending outward. One end of the liquid outlet channel 162 is connected to the liquid outlet nozzle 161, and the other end is connected to the mounting channel 151. The pressing portion 160 can rotate relative to the lock cover 120 following the mounting portion 150. Among them, the screw thread 110 is provided with a first positioning portion, and the bottle body 100 is provided with a second positioning portion which can cooperate with the first positioning portion for positioning.

[0038] In the above structure, by providing a first positioning portion on the screw thread 110, the screw thread 110 and the bottle body 100 can be positioned in cooperation with the second positioning portion on the bottle body 100. By dividing the pressing head into a mounting portion 150 and a pressing portion 160 that are independent of each other, during assembly, the mounting portion 150 is first installed on the lock cover 120 on the screw thread 110, and then according to the position of the first positioning portion on the screw thread 110, the position of the first positioning portion on the screw thread 110 is used as a reference to adjust the direction of the liquid outlet nozzle 161 and directionally insert the pressing portion 160 into the pressing portion 160, so that after the screw thread 110 and the bottle body 100 are positioned and connected, the liquid outlet nozzle 161 faces a preset direction. Therefore, during assembly, the liquid nozzle 161 and the screw thread 110 can be positioned by the first positioning portion on the screw thread 110, and the screw thread 110 and the bottle body 100 can be positioned by the first positioning portion and the second positioning portion, thereby finally achieving the positioning between the liquid nozzle 161 and the bottle body 100, thereby making the positioning between the liquid nozzle 161 of the pressing head and the bottle body 100 more convenient and accurate, and facilitating the consistency of the relative directions between the liquid nozzles 161 of each pressing head and the bottle body 100 in the mass production of the pressing pump.

[0039] It is understandable that, since the first positioning portion can cooperate with the second positioning portion to position the screw thread 110 and the bottle body 100, the relative position between the screw thread 110 and the bottle body 100 is fixed after assembly, so it is only necessary to insert the pressing portion 160 into the mounting portion 150 with reference to the position of the first positioning portion on the screw thread 110 during assembly, so that the liquid outlet nozzle 161 of the pressing portion 160 and the bottle body 100 can be positioned. Specifically, during assembly, the position of the first positioning portion on the screw thread 110 can be used as a reference, and the liquid outlet nozzle 161 of the pressing portion 160 can be directed toward the side of the screw thread 110 where the first positioning portion is provided, and the pressing portion 160 can be inserted downward into the mounting portion 150, so that the assembled liquid outlet nozzle 161 is directed toward the side of the bottle body 100 where the second positioning portion is provided, thereby achieving the positioning assembly of the liquid outlet nozzle 161 and the bottle body 100.

[0040] It can be understood that when the pressing portion 160 of the embodiment of the utility model is in use, the mounting portion 150 can be rotated, and the mounting portion 150 drives the pressing portion 160 to rotate together and move upward relative to the locking cover 120. When the mounting portion 150 is disconnected from the locking cover 120, the pressing portion 160 can be pressed downward to drive the mounting portion 150 and the main column 140 to move downward, so that the liquid in the accommodating cavity 103 can be drawn to the liquid outlet 161.

[0041] Reference Figures 2 to 8 In some embodiments, the first positioning portion is disposed on the inner wall of the screw thread 110 , and the second positioning portion is disposed on the outer wall of the bottle mouth 101 . The second positioning portion can abut against the first positioning portion and prevent the screw thread 110 from rotating.

[0042] In the above structure, when the screw thread 110 is installed on the bottle mouth 101 of the bottle body 100, the screw thread 110 is rotated so that the screw thread 110 moves downward relative to the bottle mouth 101. When the screw thread 110 rotates until the first positioning portion abuts against the second positioning portion, the second positioning portion can prevent the screw thread 110 from continuing to rotate, so that the first positioning portion on the screw thread 110 is located on the side of the bottle mouth 101 where the second positioning portion is provided, thereby achieving the positioning of the screw thread 110 and the bottle body 100, with a simple structure and convenient positioning. Therefore, when assembling, the pressing portion 160 is inserted into the mounting portion 150 with reference to the position of the first positioning portion on the screw thread 110, so that the liquid outlet 161 of the pressing portion 160 can be positioned with the bottle body 100. Specifically, during assembly, the liquid nozzle 161 can be oriented toward the side of the screw thread 110 where the first positioning portion is provided and the pressing portion 160 can be inserted into the mounting portion 150. Then, after assembly, the liquid nozzle 161 of the pressing portion 160 can be oriented toward the side of the bottle mouth 101 where the second positioning portion is provided, thereby achieving positioning between the liquid nozzle 161 and the bottle body 100.

[0043] Reference Figures 1 to 8The outer diameter of the bottle body 100 in the left-right direction is greater than the outer diameter of the bottle body 100 in the front-back direction. The liquid outlet nozzle 161 is arranged toward the side of the screw thread 110 where the first positioning portion is provided, and the second positioning portion is located on the left or right side of the bottle mouth 101.

[0044] In the above structure, during assembly, the position of the first positioning portion on the screw thread 110 is used as a reference, the liquid outlet nozzle 161 is directed toward the side of the screw thread 110 provided with the first positioning portion, and the pressing portion 160 is inserted into the mounting portion 150. After the screw thread 110 is positioned and installed on the bottle mouth 101, the first positioning portion on the screw thread 110 abuts against the second positioning portion on the bottle mouth 101. Since the second positioning portion is located on the left or right side of the bottle mouth 101, the first positioning portion on the screw thread 110 is located on the side of the bottle mouth 101 provided with the second positioning portion, thereby making the liquid outlet nozzle 161 directed toward the side of the bottle mouth 101 provided with the second positioning portion after assembly, and further making the liquid outlet nozzle 161 directed toward the side of the bottle mouth 101 provided with the second positioning portion after assembly, that is, making the liquid outlet nozzle 161 of the pressing portion 160 of the press pump directed toward the left or right side of the bottle body 100 after assembly. This not only facilitates the consistency of the relative directions between the liquid outlet nozzles 161 of each push head and the bottle body 100 during mass production of the push pumps, but also reduces the overall volume of the push pumps after being wrapped by the heat shrink film during packaging.

[0045] Reference Figures 2 to 8 In some embodiments, the first positioning portion is provided with a positioning groove 111 , and the second positioning portion is a first protrusion 102 that can be inserted into the positioning groove 111 and abut against the inner wall of the positioning groove 111 .

[0046] In the above structure, when the screw thread 110 is installed on the bottle mouth 101 of the bottle body 100, the screw thread 110 is rotated so that the screw thread 110 moves downward relative to the bottle mouth 101. When the screw thread 110 is rotated until the first protrusion 102 is inserted into the positioning groove 111 and abuts against the inner wall of the positioning groove 111, the positioning groove 111 can limit the rotation of the screw thread 110, thereby realizing the positioning of the screw thread 110 and the bottle body 100. The structure is simple and the positioning is convenient.

[0047] It can be understood that the first positioning portion is provided with a positioning groove 111, and the second positioning portion is a first protrusion 102 that can be inserted into the positioning groove 111 and abut against the inner wall of the positioning groove 111. Figures 2 to 8 In some embodiments, the positioning groove 111 may be provided in the second positioning portion, and the first positioning portion may be provided as a first protrusion 102 that can be inserted into the positioning groove 111 and abut against the inner wall of the positioning groove 111, and the present invention does not make any specific limitation on this.

[0048] Reference Figure 7 and Figure 8In some embodiments, the positioning groove 111 is formed by two second protrusions 112 arranged at intervals along the circumference of the bottle mouth 101, and the two second protrusions 112 are both provided with guide surfaces on the sides facing away from each other.

[0049] In the above structure, the setting of the guide surface can guide the first protrusion 102 to be inserted into the positioning groove 111. Specifically, when the screw thread 110 is installed on the bottle mouth 101 of the bottle body 100, the screw thread 110 is rotated so that the screw thread 110 moves downward relative to the bottle mouth 101, and the first protrusion 102 and the second protrusion 112 gradually approach each other, and the first protrusion 102 can be inserted into the positioning groove 111 along the guide surface on the second protrusion 112, thereby limiting the first protrusion 102 in the positioning groove 111, preventing the screw thread 110 from continuing to rotate, thereby realizing the positioning of the screw thread 110 and the bottle body 100, and the structure is simple and the positioning is convenient.

[0050] It is understandable that when the two second protrusions 112 are provided on the inner wall of the screw thread 110, the guide surface extends in a direction away from the positioning groove 111 to connect with the inner wall of the screw thread 110. When the two second protrusions 112 are provided on the outer wall of the bottle mouth 101, the guide surface extends in a direction away from the positioning groove 111 to connect with the outer wall of the bottle mouth 101. In addition, the guide surface can be a guide inclined surface or a guide arc surface, which is not specifically limited in the present invention.

[0051] Reference Figures 1 to 8 In some embodiments, the screw thread 110 and the lock cover 120 are an integrated structure.

[0052] In the prior art, the pump body 130 is usually inserted into the screw thread 110 and partially pressed between the inner top wall of the screw thread 110 and the top wall of the bottle mouth 101, and the lock cover 120 is inserted into the pump body 130. A gasket is also provided between the lock cover 120 and the outer top wall of the screw thread 110. The structure is complicated and inconvenient to assemble. In this embodiment, by setting the screw thread 110 and the lock cover 120 as an integrated structure, the lock cover 120 can be directly inserted into the pump body 130 during assembly, which is simple in structure and easy to assemble.

[0053] Specifically, during assembly, the locking cover 120 can be inserted into the pump body 130 and the pump body 130 can be partially pressed against the top wall of the screw thread 110, so that when the screw thread 110 is connected to the bottle mouth 101, the pump body 130 can be partially pressed between the inner top wall of the screw thread 110 and the top wall of the bottle mouth 101, thereby making the installation of the pump body 130 more stable.

[0054] Reference Figures 2 to 12 In some embodiments, the upper end of the mounting portion 150 is inserted into the liquid outlet channel 162 to connect the liquid outlet channel 162 with the main column 140 .

[0055] In the above structure, the mounting portion 150 has a mounting channel 151, and the main column 140 is inserted into the mounting channel 151. By inserting the upper end of the mounting portion 150 into the liquid outlet channel 162 of the pressing portion 160, the upper end of the mounting channel 151 is located in the liquid outlet channel 162, thereby connecting the liquid outlet channel 162 with the main column 140 through the mounting channel 151.

[0056] It is understandable that, referring to Figures 2 to 12 , the liquid outlet channel 162 is connected to the main column 140 through the installation channel 151. Specifically, the main column 140 is inserted into the installation channel 151 and the upper end of the main column 140 is located in the installation channel 151, that is, the lower end of the installation channel 151 and the main column 140 are plugged into each other and communicated with each other, and the upper end of the installation channel 151 is plugged into the installation portion 150 and communicated with the liquid outlet channel 162, thereby realizing the connection of the liquid outlet channel 162 with the main column 140 through the installation channel 151. Alternatively, in addition to this, the main column 140 can also be inserted into the installation channel 151 and the upper end of the main column 140 can be flush with the upper end of the installation channel 151 or extend to the upper end of the installation channel 151, thereby, when the upper end of the installation portion 150 is inserted into the liquid outlet channel 162 of the pressing portion 160, the upper end of the main column 140 also extends into the liquid outlet channel 162 and communicates with the liquid outlet channel 162.

[0057] Reference Figures 2 to 12 In some embodiments, the upper end of the mounting portion 150 has an annular groove 152 arranged around the outer periphery of the mounting channel 151 , and the peripheral wall of the liquid outlet channel 162 is inserted into the annular groove 152 .

[0058] In the above structure, an annular groove 152 is provided at the upper end of the mounting portion 150, and the peripheral wall of the liquid outlet channel 162 is inserted into the annular groove 152, so that the upper end of the mounting portion 150 can be inserted into the liquid outlet channel 162 and the liquid outlet channel 162 is connected to the main column 140, and the insertion between the mounting portion 150 and the pressing portion 160 is made more stable.

[0059] Reference Figures 2 to 12 In some embodiments, a first anti-rotation portion is provided on the inner wall of one side of the annular groove 152, and a second anti-rotation portion is provided on the peripheral wall of the liquid outlet channel 162. The first anti-rotation portion is provided with a first plug-in groove 153, and the second anti-rotation portion is provided with a first plug-in portion 163 that can be inserted into the first plug-in groove 153 along the up and down directions. The number of the first plug-in grooves 153 is at least two, and all the first plug-in grooves 153 are arranged at intervals in the circumferential direction of the installation channel 151, and the first plug-in portion 163 can be plugged into any first plug-in groove 153.

[0060] In the above structure, by providing at least two first plug-in grooves 153 and arranging all the first plug-in grooves 153 at intervals in the circumferential direction of the mounting channel 151, the first plug-in portion 163 can be plugged into any first plug-in groove 153, thereby enabling the pressing portion 160 to be inserted into the mounting portion 150 from different angles, thereby allowing the liquid outlet 161 of the pressing portion 160 to face different directions.

[0061] It can be understood that in the above structure, the number of the first plug-in portion 163 can be set to at least one, and the present invention does not specifically limit the specific number of the first plug-in portion 163 and the first plug-in slot 153.

[0062] It can be understood that the first anti-rotation portion is provided with a first insertion slot 153, and the second anti-rotation portion is provided with a first insertion portion 163 that can be inserted into the first insertion slot 153 in the up-down direction. Figures 2 to 12 As an exemplary illustration, in some embodiments, the first plugging slot 153 may be provided in the second anti-rotation portion, and the first plugging portion 163 may be provided in the first anti-rotation portion, and the present invention does not make any specific limitation on this.
