Description

Technical Field

[0001] This utility model belongs to the field of water pump head technology, and more specifically, it relates to an improved water pump head. Background Technology

[0002] In daily life and industrial production, the handling and dispensing of liquid products are common needs. For example, cosmetics, skincare products, cleaning supplies, and pharmaceuticals all require a convenient, hygienic device that can control the flow rate. Water pump heads, as a common liquid dispensing device, have emerged and are widely used to meet this need.

[0003] Existing water pump heads have relatively simple structures. Their working principle involves pressing the pump head to cause a piston to reciprocate within the pump body, thereby changing the pressure inside the pump body and enabling the intake and expulsion of liquid, facilitating the dispensing of liquid from containers. However, due to limitations in the structural design, it is difficult to control the amount of liquid dispensed with each press. This can be inconvenient for users of products that require controlled dosage, such as pharmaceuticals and cosmetic serums. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an improved water pump head, which solves the technical problem that traditional water pump heads are difficult to control the amount of liquid dispensed with each press, causing inconvenience to users.

[0005] The purpose and effect of this utility model in improving the pump head are achieved by the following specific technical means:

[0006] An improved water pump head includes a mounting base;

[0007] The mounting base has a mounting slot and two sets of limiting holes at one end. The limiter is installed in the mounting slot. The limiter has two sets of limiting through holes at one end. The two sets of limiting through holes correspond one-to-one with the two sets of limiting holes. A limit rod is installed between the limiting through holes and the limiting holes.

[0008] The inner wall of the limiter is provided with a first limiting groove and a second limiting groove. The first limiting groove is provided with two sets of first pressing through grooves on the side corresponding to the second limiting groove. A first limiting ring is installed between the limiter and the pressing rod. The pressing rod passes through the limiter.

[0009] The above solution further includes: two sets of protrusions are provided on both sides of the first limiting ring, corresponding to the two sets of the first pressing grooves respectively;

[0010] The bottom of the second limiting groove is also provided with two sets of second pressing grooves, and both ends of the first pressing groove and the second groove are provided with chamfers.

[0011] The above solution further includes: one end of the mounting base is connected to the suction component, the suction component includes a mounting frame, one end of the mounting frame is provided with a mounting through groove, one end of the mounting through groove is provided with a limit ball, the other end of the mounting through groove is provided with a connecting shaft, one end of the connecting shaft is provided with a mounting groove, and a return spring is provided between the mounting groove and the limit ball.

[0012] The above solution further includes: a mounting cover is engaged between the mounting base and the mounting frame, one side of the mounting cover is provided with anti-slip stripes, and one end of the mounting cover is equipped with a waterproof gasket.

[0013] The above solution further includes: a filter sleeve is installed at the other end of the mounting frame, and a fastening rubber ring is installed at one end of the filter sleeve.

[0014] The above solution further includes: a second limiting ring is installed between the connecting shaft and the mounting frame.

[0015] The above solution further includes: a pressing pump head is installed at one end of the pressing rod, an anti-slip cover is installed at one end of the pressing pump head, a liquid outlet pipe is installed on one side of the pressing pump head, and a pressurizing nozzle is installed at one end of the liquid outlet pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By restricting the protruding part of the limiting ring installed on the pressing rod within the first or second limiting groove, it can only rotate left and right. At this time, the pressing rod cannot move up and down. When the pressing pump head is rotated to the right, the protruding part also moves to the right. The chamfers set at both ends of the first and second pressing grooves will prevent the protruding part from continuing to rotate to the right. When the user forcefully rotates it to the right, the chamfers can be broken, and the protruding part will move to the first pressing groove. Because the chamfers are set at both ends of the pressing groove, they prevent it from continuing to rotate left and right, allowing it to move only up and down. This restricts the stroke of the pressing rod and solves the problem of difficulty in controlling the amount of liquid dispensed with each press in the prior art.

[0018] 2. The filter sleeve installed at one end of the mounting frame prevents foreign objects from being sucked into the pump body and jamming the limit ball, thus preventing insufficient pressure difference and failure to dispense liquid when pressed. The fastening rubber ring installed inside the filter sleeve applies pressure to the inner and outer layers when the conduit is installed in the interlayer of the fastening rubber ring. However, due to the interaction of forces, the inner and outer layers also apply pressure to the conduit at the same time, which clamps the conduit. Because the rubber material has a high coefficient of friction, the conduit installed in the fastening rubber ring will not fall off due to shaking or other factors. Attached Figure Description

Detailed Implementation

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 5 As shown:

[0029] The mounting base 9 has a mounting slot and two sets of limiting holes at one end. The limiter 12 is installed in the mounting slot. The limiter 12 has two sets of limiting through holes 11 at one end. The two sets of limiting through holes 11 correspond one-to-one with the two sets of limiting holes. A limit rod 13 is installed between the limiting through holes 11 and the limiting holes. The limit rod 13 prevents the limiter 12 from rotating.

[0030] The inner wall of the limiter 12 is provided with a first limiting groove 25 and a second limiting groove 26. The first limiting groove 25 and the second limiting groove 26 are respectively provided with two sets of first pressing through grooves 15. A first limiting ring 17 is installed between the limiter 12 and the pressing rod 5. The pressing rod 5 passes through the limiter 12. The two sides of the first limiting ring 17 are respectively provided with two sets of protrusions 16 corresponding to the two sets of first pressing through grooves 15. By inserting the protrusions 16 into the first limiting groove 25, the stroke of the pressing rod 5 can be restricted, so that it cannot be pressed down. The same applies when the protrusions 16 are inserted into the second limiting groove 26.

[0031] The bottom of the second limiting groove 26 is also provided with two sets of corresponding second pressing grooves 24. Both ends of the first pressing groove 15 and the second pressing groove 24 are provided with chamfers 27. The chamfers 27 ensure that the protrusion 16 will not be easily restricted in its travel when it rotates to the first pressing groove 15, thus affecting the user experience.

[0032] One end of the mounting base 9 is connected to the suction assembly, which includes a mounting frame 1. One end of the mounting frame 1 has a mounting groove, and a limit ball 3 is installed at one end of the mounting groove. The other end of the mounting groove has a connecting shaft 2, and one end of the connecting shaft 2 has a mounting groove. A return spring 4 is installed between the mounting groove and the limit ball 3. The installation of the limit ball 3 acts as a one-way valve, preventing the sucked liquid from flowing back into the bottle. The setting of the return spring 4 causes the air pressure inside the device to be different from the external air pressure when pressed, creating a pressure difference that allows the liquid to be sucked into the device. It also allows the pressing rod 5 to extend and retract back and forth, making it convenient to press and pick up the liquid.

[0033] The other end of the pressing lever 5 is equipped with a pressing pump head 6. The setting of the pressing pump head 6 changes the liquid flow direction, causing the liquid to move along a predetermined trajectory, making it easier to press. One end of the pressing pump head 6 is equipped with an anti-slip cover 14, which makes it less likely to slip during pressing and cause liquid to spill. A liquid outlet pipe 7 is installed on one side of the pressing pump head 6, and a pressure boosting nozzle 8 is installed at one end of the liquid outlet pipe 7. The liquid outlet pipe 7 makes it easier for the user to collect the liquid and prevents the liquid from sticking to the pressing pump head 6. The pressure boosting nozzle 8 makes the liquid flow more smoothly and prevents the liquid from being unable to be used normally due to insufficient pressure.

[0034] A mounting cover 19 is fitted between the mounting base 9 and the mounting frame 1. The mounting cover 19 has anti-slip stripes 20 on one side to prevent slipping when unscrewing the cap and make it easier to change the liquid inside the bottle. A waterproof gasket 18 is installed at one end of the mounting cover 19 to prevent the internal liquid from spilling out of the bottle.

[0035] A filter sleeve 23 is installed at the other end of the mounting frame 1. A fastening rubber ring 21 is installed at one end of the filter sleeve 23. The filter sleeve 23 prevents some foreign objects from being sucked into the device, so that the device will not malfunction due to the inhalation of foreign objects. The fastening rubber ring 21 prevents the water pipe from falling out of the bottle due to external reasons.

[0036] A second limiting ring 22 is also installed between the connecting shaft 2 and the mounting frame 1 to prevent the internal air pressure from leaking out and causing insufficient air pressure.

[0037] The specific usage and function of this embodiment: When using the improved water pump head, rotate the pump head 6 out of the mounting base 9, place your palm on the upper end of the anti-slip cover 14, and press down hard. The liquid in the bottle will spray out from the pressurizing nozzle 8. Alternatively, press down slightly and then rotate to the right. At this time, the protrusion 16 will enter the limiting slot and be limited and locked by the chamfer 27. This limits the height of the pressing rod 5, thereby limiting the amount of liquid output when pressing. After using the device, the pump head 6 can also be rotated to the right. At this time, the pump head 6 will not be able to be pressed down. When using it, continue to rotate to the right to unlock it, preventing the liquid from being squeezed out due to external reasons and causing pollution and waste.
