Definitions
- the invention belongs to daily necessities, and is mainly installed on a bottle cap, and the water agent or the emulsion-like cleaning beauty product in the bottle is pumped out by hand pressing. Background technique
- the existing bath or lotion pumps are named according to their use or liquid form, and their structures are identical. They are all reciprocating piston pumps.
- the bath pump has been connected to the cap, and the tube and nozzle are configured to supply the market. It is a general-purpose product that has been widely used for many years, yet it is inefficient, regardless of material utilization or strength.
- the 3 ml bath pump purchased from the workshop was re-measured.
- the average height of the bathing pump cylinder was 86 mm, and the connecting section of the guiding tube was 16 mm.
- the balancing hole of the bathing pump was on the cylinder wall, 12 legs away from the cylinder port.
- the piston In order to avoid the piston pumping out, the piston must be installed below the cylinder leg 12, so the upper part of the cylinder block is the effective part of the cylinder block, the pump cylinder section should be 70 mm; and the piston height is 10 mm, according to which the piston can be calculated
- the piston stroke is 14.28%; the piston stroke is 15 mm, and the pump cylinder height is only 21. 4%. It can be seen that the stroke ratio for pumping is very low.
- the piston needs strict sealing on the inner wall of the pump, which inevitably brings static friction and dynamic friction resistance. Because the pump body is long, in order to facilitate the mold release, a large draft slope is required, which causes the piston to move downward when the piston moves downward. Increase to the maximum at the end of the stroke.
- the bead check valve is often used, because of its simple structure and reliable use, but the fluid resistance is very large. If a larger diameter bead is used, the annulus is limited by the diameter of the tube; if a smaller diameter bead is used, the diameter of the orifice that forms a seal with the bead is smaller, which also increases the fluid resistance.
- the resistance of the fluid is proportional to the square of the flow velocity, and the flow velocity is inversely proportional to the square of the pipe diameter. Therefore, the resistance is proportional to the fourth power of the pipe diameter, so the small diameter and small annular gap have a great influence on the resistance. It can be seen that the existing bath pump has the bead check valve installed at the smallest diameter of the pressure rod outlet, which is a big drawback.
- the maximum diameter of the plunger is at the coupling end with the piston and is therefore the preferred position for the outlet check valve.
- the inlet check valve should also not be installed in the inlet pipe.
- the resistance of the inlet check valve is too large, resulting in an increase in the negative pressure in the pump body. Therefore, a larger elastic force is required to overcome the fluid resistance, and a spring with a larger wire diameter is required. Therefore, the inlet check valve should be installed in the open position of the bottom of the tank, and the larger diameter check valve should be used.
- Patent 1 ⁇ Reciprocating Elastic Membrane Pump>
- Patent 2 ⁇ Pushing Elastic Sac Pump>
- the two patents actually use the external components of the existing piston bath pump, including the bottle cap, the pump body, the pump cover, the pressure bar, the nozzle and the sealing ring.
- the connection relationship of the components is also substantially the same; the elastic film and the elastic bag are both
- the bath pump is drained by the pressure, and the liquid is sucked by the rebound; the elastic membrane and the elastic bladder also replace the functions of the piston and the return spring, and overcome the friction caused by the "dynamic seal" of the piston. Therefore, if the elastic film and the elastic bladder are regarded as elastic members, the identity of the two bath pump structures is greater than the difference.
- the elastic bladder can be regarded as a thick elastic membrane.
- the difference is that the elastic membrane utilizes the tensile and rebound characteristics of the thin elastomer.
- the elastic bladder utilizes the compression, tortuosity and rebound characteristics of the thick elastic body. In fact, tensile deformation can be achieved by applying a force to the elastic bladder.
- the relationship with the inner wall of the pump may be selected to contact or not contact the inner wall of the pump as required by the design.
- the balance port to the cap, and the elastic member can be installed on the pump body to reduce the height of the pump body by 10mm.
- the inner diameter of the pump body is 15mm, and the inner diameter of the pump body is 15mm, and the inner diameter of the pump body is 19mm. If it is still 3ml, the stroke is only 9.4mm. A total reduction of about 19mm in height.
- the outlet check valve is changed to a loose-leaf check valve, which is installed at the joint of the elastic member at the maximum diameter of the pressure rod.
- the inlet check valve is changed to a loose-leaf check valve, which is installed at the open end of the cylinder and takes a larger diameter.
- the loose-leaf check valve has an almost fully open and fully closed property with minimal drag characteristics.
- the elastic member is an elastic film or an elastic bladder. Most of them do not require a spring, or a conical spring can be used to reduce the height of 39 mm, that is, to save nearly 50% of the cylinder material.

- the pump cover presses the pump port and fixes and seals the elastic member, and fixes the connection between the bottle cap and the pump body; the cylinder disc coincides with the bottom ring of the cap in the cap, and the annular gap between the cylinder and the cap is inserted
- the sealing ring is inserted into the bottom nozzle of the pump body, and the inlet check valve is arranged in the open part of the pump body; the elastic member is in the pump body, a port of the pressing rod is fitted with the elastic member to form a seal, and the pressure rod cavity has an outlet One-way valve, the other end of the pressure rod is coupled to the nozzle.
- the pump body disc and the bottle cap respectively have balance holes, and the two balance holes are opposite; the knife edge is formed on both sides of the seal ring facing the center of the two balance holes to form a unidirectional loose leaf, the internal pressure of the bottle When lowered, the air outside the bottle is pushed through the balance hole to push the unidirectional leaf into the bottle; the liquid in the bottle can be kept closed.
- the three should also have a positioning logo.
- the pressure rod When using the hand to press the nozzle, the pressure rod is moved downward, and the elastic member is elastically deformed in the pump body, and pressed to the end, and the lower end of the elastic member is close to the bottom of the pump body, and the volume of the pump body under the elastic member in the process
- the internal pressure of the pump increases, and the inlet and outlet check valves automatically open and close under the action of pressure, and the liquid is discharged through the outlet of the elastic member, the pressing rod, and the nozzle.
- the external structure consisting of the three parts of the pump cover, the cap and the pump body follows the structure of a conventional piston pump. In fact, it is not necessary, and the pump cover and the cap or the pump body and the cap can be combined and injection molded.
- the elastic member can be pumped into the nozzle because the cross-sectional area of the nozzle is equivalent to that of the cap.
- the elastic component pump installed in the nozzle comprises: a pump body, an inlet check valve, an elastic member, a pressure bar, an outlet check valve, a pump cover, a nozzle; the pump body and the nozzle are injection molded at one time, and the nozzle inlet pipe is at the pump At the bottom of the body, an outlet check valve is installed in the nozzle; the opening of the pump body has a joint portion, the mouth portion of the elastic member is extended on the joint portion of the pump body, the pump cover is fixed to the cylinder mouth and the pressure bar is stabilized; one end of the pressure rod and the elastic The rounded mouth of the component is fitted to form a seal, and the inlet check valve is provided in the cavity of the pressure bar; the other end of the pressure bar is connected to the cap interface, and the lead pipe is connected, and the lead pipe is located in the bottle cap and extends into the bottle.
- the elastic member is installed in the pump body, and the pump body is placed in the cap, the appearance and function of the pump _ same.
- the elastic member is an elastic bladder, it also has an external function, that is, the external cap can also be externally placed on the spray head; the elastic bladder can also include a nozzle and a structure including the cap; the external elastic bladder is also convenient. Beautify the shape, the shape that can form a semi-cavity can be utilized, so there is more room for play.
- the pump body has a joint portion, which refers to a structure of the pump body for coupling and sealing with the elastic member, such as a pump body mouth or a pump body disc, the surface of which can be toothed. Or a dimple or a bead;
- the elastic member has an outer edge, and the outer edge refers to a structure which is designed in accordance with the sealing and coupling relationship of the pump body joint portion, or is simply a circular ring or a band fitting.
- the structure of the market not only.
- the comb can be pumped, and the comb can be used to pump the liquid between the comb teeth of the comb.
- the motor or other actuating mechanism reciprocates the diaphragm, so it is also called a diaphragm pump.
- the membrane of the diaphragm pump is only for isolation, avoiding the erosion of harmful suspended solids or chemicals in the liquid.
- Elastic members are made of elastomeric materials, and as new materials continue to emerge, they offer more options for elastomeric materials such as TPE, TPV, TPR, and TPU that can be used in food hygiene products. By designing the shape and thickness of the elastic member or the cooperation with the metal spring, it is not difficult to obtain an ideal elastic member pump product.
- the inlet and outlet check valves used in the elastic member pump are loose-leaf check valves, loose-leaf type
- the one-way valve is also made of elastomer material, which is composed of a middle leaflet, an outer positioning and a folding position.
- the diameter of the leaf is larger than the nozzle to be sealed; there is an annular gap between the leaflet and the positioning.
- the straight line of the folding groove provides the rotation axis of the leaflet.
- the cross-sectional shape, width and thickness of the folding position can be used to design the minimum force and maximum opening angle required for the loosening of the loose leaf.
- the former needs to consider the influence of the buoyancy of the one-way valve on the liquid while the latter needs to consider the angle too large. Significantly lowering the resistance may cause the rebound of the loose-leaf to be slow.
- the outlet check valve has the same structure as the inlet check valve.
- the inlet check valve It is necessary to consider the influence of the buoyancy of the inlet check valve in the liquid, and it is also expected that when the bottle is dumped, the one-way leaflet can still resist the height of the liquid column and avoid the possibility of liquid leakage, so it is necessary to design the leaflet to the nozzle, The normally closed state of the liquid column, therefore, the outlet resistance will increase, but the increased force for hand pressing is limited. If the inlet check valve is used to increase the sealing of the liquid column, the suction resistance will be increased and the negative pressure inside the cylinder will be increased. Therefore, the outlet check valve should be used for the sealing of the liquid column.
- the external structure of the bath pump consisting of the pump cover, the cap and the pump body is not mentioned.
- the pump cover and cap or the pump body and cap are combined and injection molded, retaining their original name only for the convenience of describing the spatial position and connection relationship with other components.
