Description

TECHNICAL FIELD

[0001] The application relates to the technical field of pump heads, and particularly relates to a novel emulsion press pump head. BACKGROUND

[0002] In daily life, liquid products such as emulsions, shampoos and shower gels are favored and widely used by consumers due to their convenient use and various functions. The packaging design of these products is of great significance to improving user experience, ensuring product quality and promoting product sales. Among them, the performance and function of the emulsion press pump head as a common component in the packaging of these products cannot be ignored.

[0003] The traditional emulsion press pump head usually relies on a spring and a one-way ball valve system to realize the functions of pressing and rebounding. However, the spring is prone to fatigue and wear in the long-term repeated compression and release process. With the passage of time, the rebounding force of the spring will gradually weaken, and even complete failure may occur, which directly affects the normal operation of the pump head and the user experience.

[0004] Therefore, the application provides a novel emulsion press pump head to solve the above problems. CONTENT OF THE INVENTION

[0005] The application provides a novel emulsion press pump head, which aims to solve the problems that the spring in the existing emulsion press pump head is prone to fatigue and wear due to long-term repeated use, the rebounding force is weakened or fails, the normal operation of the pump head is affected, and the user experience is affected and the like.

[0006] To achieve the above-mentioned purpose, the application provides the following technical scheme: a novel emulsion press pump head, comprising a fixed cylinder, a bottle mouth cover fixedly sleeved at one end of the fixed cylinder and coaxially arranged with the fixed cylinder, a suction pipe fixedly arranged at an end of the fixed cylinder away from the bottle mouth cover and coaxially arranged with the fixed cylinder, a storage pipe fixedly arranged in the fixed cylinder and in communication with the suction pipe, a pressing head penetrating through the bottle mouth cover and the fixed cylinder and slidingly connected in the bottle mouth cover, a push rod penetrating through the bottom end of the pressing head and slidingly connected in the pressing head and outside the storage pipe, and a rebounding assembly arranged in the fixed cylinder corresponding to the outside of the storage pipe and connected with the push rod and the pressing head, wherein the push rod is in communication with the storage pipe and the pressing head.

[0007] The rebound assembly comprises a first elastic telescopic tube arranged in the fixed cylinder and sleeved outside the push rod near one end of the storage tube, a first inelastic fixing member fixedly arranged at the top end of the first elastic telescopic tube and fixedly connected with the bottom end of the pressure head, a second inelastic fixing member fixedly connected at one end of the first elastic telescopic tube away from the first inelastic fixing member and fixedly connected with the outside of the push rod, a second elastic telescopic tube sleeved outside the storage tube and fixedly connected with the second inelastic fixing member away from the push rod, and an inelastic connecting member fixedly connected at the bottom end inside the fixed cylinder and fixedly connected with the second elastic telescopic tube away from the push rod. By introducing the first elastic telescopic tube and the second elastic telescopic tube as the main part of the rebound assembly, rebound force can be provided after pressing, not only making the user feel smooth rebound when releasing the pressure head, improving the comfort of use, but also ensuring the stability and durability in long-term use, avoiding the problem that the spring in the traditional pump head may be worn or failed after long-term use.

[0008] Preferably, in order to ensure the elastic telescopic property and durability of the first elastic telescopic tube and the second elastic telescopic tube, the first elastic telescopic tube and the second elastic telescopic tube are both made of PV material; PV material has good elasticity and plasticity, so that the first elastic telescopic tube and the second elastic telescopic tube can maintain stable telescopic property during pressing and releasing, and PV material can resist corrosion of chemical substances such as acid and alkali, so as to ensure that the pump head is not damaged when contacting chemical substances such as emulsion for a long time.

[0009] Preferably, in order to ensure liquid outlet and sealing, the pressure head is provided with a liquid outlet, and the side surface of the push rod away from the storage tube is provided with a notch in communication with the liquid outlet; the design of the liquid outlet and the notch not only enables the emulsion to flow smoothly from the push rod into the pressure head and be finally squeezed out, but also enables the pump head to form effective sealing when not in use, preventing emulsion leakage. This sealing method does not rely on the traditional one-way ball valve, thereby avoiding the problems of wear, failure or blockage of the one-way ball valve that may occur due to long-term use.

[0010] Preferably, in order to ensure the compression accuracy of the first elastic telescopic tube, an annular stopper is fixedly arranged at the top end inside the pressure head, and an annular groove for contact limiting of the annular stopper is fixedly arranged outside the top end of the push rod; the cooperation of the annular stopper and the annular groove limits the movement distance of the pressure head on the push rod, thereby ensuring the compression accuracy of the first elastic telescopic tube during pressing, and helping the liquid outlet and the notch to be in smooth communication to maintain the stable output performance of the pump head.

[0011] Preferably, in order to ensure that the pressure head does not enter the bottle cap excessively, a limiting block is fixed on one side of the top end of the bottle cap, which is in contact with the outside of the top end of the pressure head. The pressure head is provided with a limiting groove corresponding to the position of the limiting block. The cooperation of the limiting block and the limiting groove limits the downward distance of the pressure head, preventing the pressure head from being pressed into the bottle cap excessively during pressing, and helping to maintain the overall structure and functional integrity of the pump head.

[0012] Preferably, in order to ensure the accurate compression of the second elastic tube, a first channel and a second channel are provided inside the push rod and communicate with the storage tube. The inner diameter of the first channel is consistent with the outer diameter of the storage tube, and the inner diameter of the second channel is smaller than the outer diameter of the storage tube. The design of the first channel and the second channel ensures smooth flow of the emulsion. At the same time, the inner diameter of the first channel is consistent with the outer diameter of the storage tube, and the inner diameter of the second channel is smaller than the outer diameter of the storage tube. When the first elastic tube is compressed and continues to be pressed, the downward pressure of the pressure head can drive the push rod to move downward, and at the same time, it can limit the distance of the push rod moving on the storage tube, ensuring the integrity of the function of the pump head.

[0013] The new emulsion pressing pump head introduces the first elastic tube and the second elastic tube as the main part of the rebound component, which can provide rebound force after pressing. Not only can the user feel smooth rebound when releasing the pressure head, but also can improve the comfort of use, ensure the stability and durability in long-term use, and avoid the problem of wear or failure of the traditional spring in long-term use.

[0014] The new emulsion pressing pump head is designed by the cooperation of the liquid outlet and the notch, which not only makes the emulsion flow smoothly from the push rod into the pressure head and finally be squeezed out, but also forms an effective seal when not in use to prevent emulsion leakage. This sealing method does not rely on the traditional one-way ball valve, thereby avoiding the problems of wear, failure or blockage of the one-way ball valve due to long-term use.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] The present embodiment provides a new type of emulsion pressing pump head, such as Figures 1-4As shown, the new emulsion push pump head includes a fixed cylinder 2, a bottle mouth cover 1 fixedly sleeved at one end of the fixed cylinder 2 and coaxially arranged with the fixed cylinder 2, a suction pipe 3 fixedly arranged at an end of the fixed cylinder 2 away from the bottle mouth cover 1 and coaxially arranged with the fixed cylinder 2, a storage pipe 4 fixedly arranged in the fixed cylinder 2 and in communication with the suction pipe 3, a pressure head 5 penetrating through the bottle mouth cover 1 and the fixed cylinder 2 and slidingly connected in the bottle mouth cover 1, a push rod 6 penetrating through a bottom end of the pressure head 5 and slidingly connected in the pressure head 5 and outside the storage pipe 4, and a rebound assembly 7 arranged in the fixed cylinder 2 corresponding to the outside of the storage pipe 4 and connected with the push rod 6 and the pressure head 5, the push rod 6 being in communication with the storage pipe 4 and the pressure head 5; the rebound assembly 7 includes a first elastic telescopic pipe 72 arranged in the fixed cylinder 2 and sleeved outside an end of the push rod 6 close to the storage pipe 4, a first non-elastic fixing member 71 fixedly arranged at a top end of the first elastic telescopic pipe 72 and fixedly connected with the bottom end of the pressure head 5, a second non-elastic fixing member 73 fixedly connected at an end of the first elastic telescopic pipe 72 away from the first non-elastic fixing member 71 and fixedly connected with the outside of the push rod 6, a second elastic telescopic pipe 74 sleeved outside the storage pipe 4 and fixedly connected with the second non-elastic fixing member 73 away from the push rod 6, and a non-elastic connecting member 75 fixedly connected at a bottom end inside the fixed cylinder 2 and fixedly connected with an end of the second elastic telescopic pipe 74 away from the push rod 6.

[0029] In order to ensure the elastic telescopic performance and durability of the first elastic telescopic pipe 72 and the second elastic telescopic pipe 74, the first elastic telescopic pipe 72 and the second elastic telescopic pipe 74 are both made of PV material; the PV material has good elasticity and plasticity, so that the first elastic telescopic pipe 72 and the second elastic telescopic pipe 74 can maintain stable telescopic performance during pressing and releasing, and the PV material can resist corrosion of chemical substances such as acid and alkali, so as to ensure that the pump head will not be damaged when in long-term contact with emulsion and other chemicals.

[0030] In addition, in order to ensure liquid outlet and sealing, the pressure head 5 is provided with a liquid outlet 51, and an end of the push rod 6 away from the storage pipe 4 is provided with a notch 61 in communication with the liquid outlet 51; the design of the liquid outlet 51 and the notch 61 not only enables the emulsion to flow smoothly from the push rod 6 into the pressure head 5 and finally be squeezed out, but also enables the pump head to form effective sealing when not in use, preventing emulsion leakage; this sealing method does not need to rely on the traditional one-way ball valve, thereby avoiding the problems of wear, failure or blockage of the one-way ball valve that may occur due to long-term use.

[0031] In use, when the pressure head 5 is in an unpressed state, the first elastic telescopic pipe 72 and the second elastic telescopic pipe 74 are both in an uncompressed state, and the whole rebound assembly 7 is in a relaxed state, at this time, the liquid outlet 51 in the pressure head 5 is out of position and not connected with the notch 61 on the push rod 6, forming a sealed state to prevent the emulsion from leaking, then, when the user starts to press the pressure head 5, the pressure head 5 will slide down in the bottle cap 1, at this time, the pressure head 5 starts to squeeze the first elastic telescopic pipe 72 through the connection of the first inelastic fixing part 71, so that the first elastic telescopic pipe 72 is compressed, when the first elastic telescopic pipe 72 is compressed to the limit, at this time, the pressure head 5 and the push rod 6 abut, and the liquid outlet 51 and the notch 61 are connected, while the external air enters the push rod 6 from the liquid outlet 51 and the notch 61, so that the pressure in the push rod 6 increases and compresses the air inside the push rod 6, with the continuous pressing of the pressure head 5, the pressure head 5 will slide down together with the push rod 6, at this time, with the sliding of the push rod 6, the push rod 6 will squeeze the second elastic telescopic pipe 74 through the connection of the second inelastic fixing part 73, so that the second elastic telescopic pipe 74 is compressed outside the storage pipe 4, while the push rod 6 will slide outside the storage pipe 4 and compress the air inside the storage pipe 4, when the second elastic telescopic pipe 74 is compressed to the limit, the user stops pressing the pressure head 5, at this time, the second elastic telescopic pipe 74 rebounds first and pushes the push rod 6 to move upwards outside the storage pipe 4, at this time, a negative pressure is formed in the storage pipe 4, and the straw 3 will suck the emulsion from the bottle into the storage pipe 4 under the action of the negative pressure, when the second elastic telescopic pipe 74 rebounds to the initial position, the first elastic telescopic pipe 72 starts to rebound and pushes the pressure head 5 to move outside the push rod 6, at this time, the emulsion in the storage pipe 4 will be sucked into the push rod 6 for storage, while the liquid outlet 51 and the notch 61 are out of position to achieve sealing, when the user presses the pressure head 5 again, the emulsion stored in the push rod 6 will be discharged from the liquid outlet 51 when the liquid outlet 51 and the notch 61 are connected.

[0032] Specifically, the top end of the pressure head 5 is fixedly provided with an annular stop block 52, and the top end of the push rod 6 is fixedly provided with an annular groove 62 for contact limiting of the annular stop block 52;

[0033] When the user presses the pressure head 5, at this time, the annular stop block 52 in the pressure head 5 will move outside the push rod 6, with the continuous pressing of the pressure head 5, the annular stop block 52 will abut with the annular groove 62 outside the push rod 6, when the annular stop block 52 and the annular groove 62 abut, it represents that the first elastic telescopic pipe 72 is compressed to the limit, at this time, the liquid outlet 51 will slide down and smoothly connect with the notch 61, which is convenient for subsequent continuous pressing of the pressure head 5 and synchronous sliding of the push rod 6, on the contrary, when the user does not press the pressure head 5, the annular stop block 52 can move upwards outside the push rod 6 and away from the annular groove 62 under the rebounding action of the first elastic telescopic pipe 72, at this time, the liquid outlet 51 will be out of position with the notch 61 with the upward movement of the annular stop block 52.

[0034] Further, the bottle cap 1 is fixedly provided with a limiting block 11 on one side of the top end, which is used to contact the outer side of the top end of the pressing head 5. The pressing head 5 is provided with a limiting groove 53 corresponding to the position of the limiting block 11.

[0035] When the annular block 52 and the annular groove 62 are in contact, the first elastic telescopic pipe 72 is compressed to the limit, and the pressing head 5 continues to be pressed down. At this time, the pressing head 5 will drive the push rod 6 to slide down. In order to prevent the pressing head 5 from entering the bottle cap 1 too much, when the pressing head 5 approaches the bottle cap 1 and contacts the limiting block 11, the limiting block 11 will block the pressing head 5 from entering the bottle cap 1. At the same time, when the user does not press the pressing head 5, the pressing head 5 will rebound under the action of the rebound assembly 7, and the limiting groove 53 can ensure the stability of the pressing head 5 when it is pressed down.

[0036] Further, the push rod 6 is provided with a first channel 63 and a second channel 64 which are in communication with the storage pipe 4. The inner diameter of the first channel 63 is consistent with the outer diameter of the storage pipe 4, and the inner diameter of the second channel 64 is smaller than the outer diameter of the storage pipe 4.

[0037] It should be noted that the notch 61 is in communication with the first channel 63 and the second channel 64.

[0038] With the continuous pressing of the pressing head 5 and the downward movement of the push rod 6, since the inner diameter of the second channel 64 is smaller than the outer diameter of the storage pipe 4, when the bottom end of the second channel 64 of the push rod 6 moves close to the storage pipe 4, it will be blocked by the storage pipe 4. At this time, the push rod 6 can be prevented from continuing to slide down outside the storage pipe 4. At the same time, the second elastic telescopic pipe 74 is compressed to the limit, and when the user does not press the pressing head 5, the second elastic telescopic pipe 74 will move up outside the storage pipe 4 through the first channel 63 of the push rod 6 under the rebound action of the second elastic telescopic pipe 74, so that the emulsion entering the storage pipe 4 can smoothly enter the first channel 63, then enter the second channel 64 from the first channel 63, and finally flow from the notch 61 to the liquid outlet 51 through the second channel 64.

[0039] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical solution and concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
