[0002] Currently, traditional lotion pumps are commonly used in daily cleaning and skincare products such as hand soap, shower gel, and facial cleanser to dispense lotion, and are widely used in daily life.

However, this emulsion pump, similar to traditional emulsion pumps, suffers from the following problem: during dispensing, the stroke of the pusher cannot be precisely controlled, thus making it impossible to control the pumping volume and failing to meet user needs. Summary of the Invention

[0004] The purpose of this invention is to overcome the problem of uncontrollable pump output from the pump head and to provide an emulsion pump with adjustable pump output.

[0007] A pump output adjusting component is movably connected to the locking cover and reciprocates in the vertical direction relative to the locking cover to adjust and limit the descent distance of the push-button; the upper end of the pump core assembly is movably connected to the push-button through the pump output adjusting component.

[0008] When the pump output adjusting member moves upward relative to the locking cover and comes into contact with the push-button, the pump output adjusting member limits the descent distance of the push-button to zero.

[0009] Furthermore, the pump output adjusting component includes an adjusting stud and a top support cover connected to the upper end of the adjusting stud and capable of covering the upper end of the locking cover; the pump output adjusting component has a rod cavity channel that extends from the top end of the top support cover to the bottom end of the adjusting stud and allows the upper end of the pump core assembly to move through it.

[0010] The adjusting stud has an external thread on its outer wall; the locking cover has an internal thread on its inner wall; the adjusting stud is embedded in the inner cavity of the locking cover and is threadedly connected by the external thread and the internal thread to adjust the pump output adjusting component to reciprocate in the up and down direction relative to the locking cover.

[0011] Furthermore, the push-button includes a pressing head and a connecting tube connected to the pressing head; the connecting tube is connected to the upper end of the pump core assembly; the outer wall of the connecting tube is adapted to and movably embedded in the rod cavity; the connection between the pressing head and the connecting tube has a downward pressing surface corresponding to the top surface of the top support cover;

[0012] When the top surface of the top support cover comes into contact with the bottom pressure surface, the pump output adjustment element limits the descent distance of the push head to zero.

[0013] Furthermore, the outer peripheral wall of the top cover is provided with several vertical grooves that are evenly arranged around its central axis and extend vertically; there is a vertical protrusion between two adjacent vertical grooves.

[0014] Furthermore, the outer peripheral wall of the top cover is provided with a vertically arranged toggle part; the top of the top cover is provided with an indicator arrow part for indicating the position of the toggle part.

[0015] Furthermore, the pump core assembly is formed by assembling a main column, a secondary column, a piston, and a spring into a single unit within the pump body; the upper end of the main column can movably pass through the pump output adjustment component and communicate with the push head.

[0016] Furthermore, the check valve includes a check plug, a flow guide connector, flow guide plates, and a top rod; the upper end of the check plug is connected to the lower end of the flow guide connector, and is used to open or close the upper liquid port in the lower end of the pump body; the upper end of the flow guide connector is connected to the top rod; a plurality of flow guide plates are provided on the peripheral wall of the flow guide connector, which are evenly distributed around its central axis; two adjacent flow guide plates form a flow guide groove on the flow guide connector.

[0017] Furthermore, the lower end face of the check plug is spherical; the flow guide connector is a frustum structure with a smaller top and a larger bottom; and the top rod is cylindrical.

[0018] Furthermore, the top surface of the anti-reverse plug is a plane connected to the lower end of the guide vane.

[0019] Furthermore, the number of the guide vanes is at least five.

[0020] Compared with existing technologies, the present invention has the following advantages:

[0021] This invention combines a pump body, a pusher, a locking cap, threads, a pump core assembly, a check valve, and a pump output adjustment component. By adjusting the vertical movement of the pump output adjustment component relative to the locking cap, the downward stroke of the pusher, i.e., the distance the pusher descends, can be controlled, thus allowing for the pumping of different pump outputs. When the pump output adjustment component moves upward until the top support cap contacts the pusher top support, the downward stroke of the pusher is completely limited, i.e., the descent distance is zero, and the pump output is zero. This design, by adjusting the vertical position of the pump output adjustment component relative to the locking cap, precisely controls the pusher stroke, which is beneficial for meeting the pusher's pump output function and facilitating user needs.

Detailed Implementation

[0031] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0032] like Figures 1 to 6 As shown, an adjustable emulsion pump includes a pump body 1, a pump head 2, a locking cap 3, a threaded cap 4, a pump core assembly 5, a check valve 6, and a pump output adjusting component 7. The check valve 6 is located inside the lower end of the pump body 1 to ensure unidirectional liquid flow during pumping and prevent backflow. The pump core assembly 5 and the threaded cap 4 are assembled on the pump body 1 via the locking cap 3 to form a complete pumping system. Specifically, the pump core assembly 5 is formed by assembling a main column 51, a secondary column 52, a piston 53, and a spring 54 within the pump body 1. The assembly method of the main column 51, secondary column 52, piston 53, and spring 54 within the pump body 1 is basically the same as that of existing emulsion pumps. The pump flow rate adjustment component 7 is movably connected to the locking cap 3 and reciprocates relative to the locking cap 3 in the vertical direction to adjust and limit the descent distance of the massage head 2. The upper end of the pump core assembly 5 can movably pass through the pump flow rate adjustment component 7 and connect to the massage head 2. Specifically, the upper end of the main column 51 can movably pass through the pump flow rate adjustment component 7 and communicate with the massage head 2. When the pump flow rate adjustment component 7 moves upward relative to the locking cap 3 and comes into contact with the massage head 2, the pump flow rate adjustment component 7 limits the descent distance of the massage head 2 to zero. By moving the pump flow rate adjustment component 7 to change its position relative to the locking cap 3, the maximum descent distance of the massage head 2 can be linearly adjusted, thereby controlling the single pump flow rate.

[0033] This adjustable emulsion pump combines a pump body 1, a pump head 2, a locking cap 3, a thread 4, a pump core assembly 5, a check valve 6, and a pump output adjustment component 7. By adjusting the vertical movement of the pump output adjustment component 7 relative to the locking cap 3, the downward stroke of the pump head 2 is controlled, i.e., the descent distance of the pump head 2, thus allowing for the pumping of different pump volumes. When the pump output adjustment component 7 moves upward until the top support cap 72 contacts the top support of the pump head 2, the downward stroke of the pump head 2 is completely restricted, i.e., the descent distance is zero, and the pump output is zero. This design, by adjusting the vertical position of the pump output adjustment component 7 relative to the locking cap 3, precisely controls the stroke of the pump head 2, which is beneficial for meeting the function of the pump head 2's spray volume and is convenient for users.

[0034] In this embodiment, the pump output adjusting component 7 includes an adjusting stud 71 and a top support cover 72 connected to the upper end of the adjusting stud 71 and covering the upper end of the locking cover 3; the pump output adjusting component 7 has a rod cavity 73 extending from the top end of the top support cover 72 to the bottom end of the adjusting stud 71 and allowing the upper end of the pump core assembly 5 to move through; the outer wall of the adjusting stud 71 has an external thread 711; the inner wall of the locking cover 3 has an internal thread 31; the adjusting stud 71 is embedded in the inner cavity of the locking cover 3 and is threadedly connected to the internal thread 31 through the external thread 711 to adjust the reciprocating movement of the pump output adjusting component 7 relative to the locking cover 3 in the vertical direction. By combining the adjusting stud 71 and the top support cover 72, when the user rotates the top support cover 72, the top support cover 72 drives the adjusting stud 71 to move upward or downward along the axial direction of the locking cover 3, thereby controlling the downward stroke of the push-button 2, i.e., the descent distance of the push-button 2. The push-button 2 is pressed down by the user to the position where it contacts the top of the top support cover 72. This position determines the compression stroke of the pump core assembly 5, thereby controlling the pump output, so that different specifications of pump output can be pumped out. When the top support cover 72 moves upward and contacts the top of the push-button 2, the downward stroke of the push-button 2 is completely restricted, and the push-button 2 cannot be pressed down, i.e., the descent distance is zero. At this time, the pump output is zero, and the pump core assembly 5 does not work.

[0035] To better rotate the pump output adjusting component 7 and adjust its position relative to the locking cover 3, the outer peripheral wall of the top support cover 72 is provided with several vertical grooves 721 evenly arranged around its central axis and extending vertically; a vertical protrusion 722 is provided between two adjacent vertical grooves 721. By combining the vertical grooves 721 and the vertical protrusion 722, the contact friction between the hand and the top support cover 72 can be better enhanced when rotating the top support cover 72, making the rotation of the top support cover 72 easier and more convenient. In this way, the precise control of the stroke of the push-button 2 is achieved through mechanical threaded rotation adjustment.

[0036] To further adjust the top cover 72 and make rotation easier, a vertically arranged toggle part 8 is provided on the outer peripheral wall of the top cover 72; an indicator arrow part 9 is provided on the top of the top cover 72 to indicate the position of the toggle part 8.

[0037] In this embodiment, the press head 2 includes a pressing head 21 and a connecting column 22 connected to the pressing head 21; the connecting column 22 is connected to the upper end of the pump core assembly 5; the outer wall of the connecting column 22 is adapted to and movably embedded in the rod cavity 73; the connection between the pressing head 21 and the connecting column 22 has a downward pressing surface 23 corresponding to the top surface of the top support cover 72; when the top surface of the top support cover 72 abuts against the downward pressing surface 23, the pump output adjustment component 7 limits the descent distance of the press head 2 to zero. By combining the pressing head 21 and the connecting column 22, and providing a downward pressing surface 23 on the press head 2, the downward pressing surface 23 matches the top surface of the top support cover 72, and the surfaces make flat contact, which is beneficial for precise control of the stroke of the press head 2, meets the function of adjusting the spray volume, and facilitates the user's needs.

[0038] In this embodiment, the check valve 6 is improved. The check valve 6 includes a check plug 61, a flow guide connector 62, flow guide plates 63, and a top rod 64. The upper end of the check plug 61 is connected to the lower end of the flow guide connector 62, and is used to open or close the liquid inlet in the lower end of the pump body 1. The upper end of the flow guide connector 62 is connected to the top rod 64. The peripheral wall of the flow guide connector 62 is provided with a plurality of flow guide plates 63 evenly distributed around its central axis. Two adjacent flow guide plates 63 form a flow guide groove 65 on the flow guide connector 62. By setting up a check valve 61, a flow guide connector 62, a flow guide plate 63, and a top rod 64, the check valve 61 is used to open or close the liquid inlet in the lower end of the pump body 1. Through the synergistic effect of the flow guide connector 62 and the flow guide plate 63, multiple flow guide grooves 65 are formed, which facilitates the upward flow of liquid, improves the liquid inlet efficiency, enables rapid liquid discharge, and optimizes the pressing feel. At the same time, compared with the glass ball type check valve, the spring 54's constriction design and the obstruction design of the glass ball inside the lower end of the pump body 1 can be avoided, making the structural design simpler.

[0039] Preferably, the lower end face of the check plug 61 is spherical, facilitating contact sealing with the liquid inlet inside the lower end of the pump body 1. The flow guide connector 62 has a frustum-shaped structure, smaller at the top and larger at the bottom, allowing the flow guide plate 63 to form an upward angle within the flow guide connector 62. The upward angle ranges from 60° to 85°, meaning the sidewall of the frustum-shaped flow guide connector 62 has an optimized slope, causing the liquid to flow upward along the flow guide groove 65 at a set slope, which helps improve the liquid loading efficiency, accelerates liquid discharge, and optimizes the pressing feel. The top rod 64 is cylindrical, which can effectively guide or divert the liquid flowing out from the upper end of each flow guide groove 65, accelerating the liquid loading efficiency.

[0040] The lower end of the guide channel 65 is larger than its upper end, which facilitates the gathering and optimization of the liquid when it is sprayed upward. Then, through the guiding effect of the top rod 64, the liquid can be quickly fed.

[0041] To enhance the connection stability of the structure, the top surface of the anti-reverse plug 61 is a plane that connects to the lower end of the guide vane 63.

[0042] To better design and optimize the flow channel 65, the number of flow guide vanes 63 should be at least 5. The specific number can be 5, 6, 7, 8, etc., and can be designed reasonably according to requirements.

[0043] The operating principle of this adjustable emulsion pump, where the pumping volume needs to be adjusted, is as follows:

[0044] When it is necessary to control the pump output of the adjusting head 2, the user only needs to rotate the adjusting top cover 72. The top cover 72 drives the adjusting stud 71 to move upward or downward along the axial direction of the locking cover 3, thereby controlling the downward stroke of the head 2, that is, the descent distance of the head 2. The head 2 is pressed down by the user to the position where it contacts the top of the top cover 72. This position determines the compression stroke of the pump core assembly 5, thereby controlling the pump output, so that different specifications of pump output can be pumped out. When the top cover 72 moves upward and contacts the top of the head 2, the downward stroke of the head 2 is completely restricted, and the head 2 cannot be pressed down, that is, the descent distance is zero. At this time, the pump output is zero, and the pump core assembly 5 does not work.

[0045] In summary, embodiments of the present invention provide an emulsion pump with adjustable pump output, wherein,

[0046] This adjustable emulsion pump combines a pump body 1, a pump head 2, a locking cap 3, a thread 4, a pump core assembly 5, a check valve 6, and a pump output adjustment component 7. By adjusting the vertical movement of the pump output adjustment component 7 relative to the locking cap 3, the downward stroke of the pump head 2 is controlled, i.e., the descent distance of the pump head 2, thus allowing for the pumping of different pump volumes. When the pump output adjustment component 7 moves upward until the top support cap 72 contacts the top support of the pump head 2, the downward stroke of the pump head 2 is completely restricted, i.e., the descent distance is zero, and the pump output is zero. This design, by adjusting the vertical position of the pump output adjustment component 7 relative to the locking cap 3, precisely controls the stroke of the pump head 2, which is beneficial for meeting the function of the pump head 2's spray volume and is convenient for users.

[0047] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
