Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the unfolding structure of the present invention.
Fig. 3 is a schematic view of the piston pin structure of the present invention.
Fig. 4 is a schematic view of a piston tip structure according to an improved embodiment of the present invention.
The specific implementation mode is as follows:
as shown in fig. 1 to 4, a pump head for cosmetics, the pump head comprises a connecting pipe 1, a spring 2, a small and medium cover 3, a piston 4, a piston tip 5, a body 6, which are coaxially connected in sequence, wherein the upper part of the connecting pipe 1 is connected with fittings such as liquid outlets, and the like, and liquid outlet fittings of different shapes can be connected according to needs, the spring 2 is sleeved between the connecting pipe and the upper end surface of the small and medium cover 3, a cavity is formed between the spring 2 and the small and medium cover 3, the spring 2 provides the piston tip with elastic force of a return position, the piston 4 is used for sealing the stopper part of the piston tip 5, so that the piston tip 5 can be sealed in the cavity formed by the body to realize effective sealing up and down, as an improved structure, the piston 4 is of a slidable structure on the piston tip 4, an inner wall hole 53 with an upward opening and a passage hole 52 are arranged in the piston tip, and the passage, the upper sealing function in the pump head is realized, the small and middle cover 3 is used as a cover body part of the body 6, and the small and middle cover and the body are matched to form an internal cavity; the lower end surface of the small and medium cover 3 is covered on the body 6 by a clamping way, the lower end of the connecting pipe 1 is fixedly connected with the upper end of the piston tip 4, the upper half section of the piston tip 4 is slidably sleeved with the piston 4 made of elastic material, a channel hole 52 is arranged on the piston tip corresponding to the position of the piston, the channel hole is communicated with an inner wall hole 53 arranged in the upper half section of the piston tip, the key point is that the lower end of the piston tip 5 is provided with a sealing shaft 51, the bottom of the body 6 is correspondingly provided with a sealing hole 61 with the aperture matched with the sealing shaft, the sealing shaft can be inserted into the sealing hole to form an effective sealing state, the effective sealing length of the sealing shaft is shorter than the sliding length of the piston tip in the body, so that when the piston tip slides back and forth in the body, a sealing and separating state is formed between the sealing shaft and the sealing hole to complete a liquid sealing and absorbing process, the resilience of the spring is larger than the suction, the disengaged state is used to draw liquid from the bottle into the cavity to maintain proper circulation for pumping.
The specific working process is as follows: the connecting pipe is driven by external force to move the piston tip downwards, at the initial stage, the piston is in a stationary state due to the fact that the friction force of the clamping of the sliding groove is large, then the piston tip continues to move downwards, the displacement gap of the piston in the sliding groove of the piston is used up, the channel hole shielded by the piston on the piston tip is opened, the pump head is provided with an upper flow channel, meanwhile, the sealing shaft at the bottom of the piston tip is inserted into the sealing hole of the body to form a lower seal, the piston continues to move downwards with the inner wall in a sealing state, the moving downwards process is carried out, the space in the cavity is reduced, liquid in the cavity is extruded out through the upper flow channel, and when the piston tip moves to; withdrawing the external force, and enabling the pump head to enter an absorption process; at this time, the piston tip moves upwards under the driving of the spring, and the piston is fixed due to the sliding space, when the piston tip continues to move and enables the passage hole to be in the piston shielding position, the upper flow passage is closed, the piston tip continues to move upwards, at this time, because the sealing shaft at the bottom of the piston tip is always in the sealing hole of the body, the lower seal is also closed, the cavity is in a vacuum state, the piston tip continuously moves upwards, the resilience force of the spring is larger than the suction force in the vacuum state formed in the ascending stage of the piston tip, the cavity is continuously in the vacuum state, when the piston tip continues to move upwards to the clearance between the sealing shaft and the sealing hole, the vacuum state is broken, the cavity starts to absorb the liquid in the bottle through the sealing hole, the piston tip moves upwards to the top, when the pressure in the cavity is balanced, the imbibing process is finished, and the next working cycle is waited.
In a preferred embodiment, the sealing shaft is cylindrical, and the upper part of the hole wall of the sealing hole is provided with a chamfer part which has a guiding function on the sealing shaft. The chamfer portion provides a guide for the seal shaft in the early stage of insertion, ensuring effective insertion of the seal shaft into the seal bore even when the direction of the component force due to depression is not forward downward.
As a more preferable embodiment, the sealing shaft has an upper cylindrical section and a lower conical section with a gradually decreasing diameter, the upper part of the hole wall of the sealing hole is provided with a chamfer, and the lower section of the sealing shaft is inserted into the sealing hole at the lowest position. The sealing shaft with a longer length is partially extended into the sealing hole, and due to the fact that the outer diameter of the sealing shaft is smaller, a reasonable gap exists between the sealing shaft and the sealing hole, and liquid or paste can be sucked into the cavity during sucking.
As a modified embodiment, the spring replacement installation position comprises the following steps: the spring is installed at this internal, the up end and the piston tip contact of spring, the bottom contact in lower terminal surface and the body of spring, the bottom of body in be equipped with the spring and accomodate the chamber.
Go up the functional structure of seal part conduct pump head, also have the structure that adopts fixed piston cooperation diaphragm formula check valve, this structure adopts other sealed form not to influence the utility model discloses an implement.
The above disclosure is only for the specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be made by those skilled in the art should fall within the protection scope of the present invention.
