FIG. 1 is a schematic diagram of the structure of the present invention.
Fig. 2 is a schematic view of the development structure of the invention.
Fig. 3 is a schematic view of the piston tip 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 embodiment is as follows:
as shown in fig. 1 to 4, a pump head of a cosmetic product, the pump head comprises a connecting pipe 1, a spring 2, a small middle cover 3, a piston 4, a piston tip 5, a body 6, and the upper part of the connecting pipe 1 is connected with liquid outlet fittings with different shapes according to the needs, the spring 2 is sleeved between the connecting pipe and the upper end face of the small middle cover 3, a cavity is formed between the spring 2 and the small middle cover 3, the spring 2 provides elastic force for the piston tip in a restoring position, the piston 4 is used for sealing the plug head part of the piston tip 5, so that the piston tip 5 can realize effective sealing up and down in the cavity formed by the body, as an improved structure, the piston 4 is in a slidable structure on the piston tip 4, an upward opening inner wall hole 53 and a channel hole 52 are arranged in the piston tip, the channel hole is shielded and opened by the sliding of the piston, the small middle cover 3 is used as a cover part of the body 6, and the small middle cover is matched with the body to form an inner cavity; the lower end face of the small and medium cover 3 is covered on the body 6 in 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 materials, a passage hole 52 is arranged on the piston tip and corresponds to the position of the piston, the passage hole is communicated with an inner wall hole 53 arranged in the upper half section of the piston tip, a sealing shaft 51 is arranged at the lower end of the piston tip 5, a sealing hole 61 with an aperture matched with the sealing shaft is arranged at the bottom of the body 6, the sealing shaft can be inserted into the sealing hole and forms 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 state and a separating state are formed between the sealing shaft and the sealing hole, the sealing liquid and the liquid suction process are completed, the resilience force of the spring is larger than the suction force of the vacuum state formed by the rising stage of the piston tip, and the separating state is used for sucking liquid in a bottle to a cavity, so that normal circulation pumping can be maintained.
The working process of the concrete use: the connecting pipe drives the piston tip to move downwards by external force, in the initial stage, the piston is in a static state because of the large friction force of clamping of the sliding groove, then the piston tip continues to move downwards, a displacement gap of the piston in the sliding groove is used up, a channel hole shielded by the piston on the piston tip is opened, an upper flow channel appears on the pump head, meanwhile, a 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 in a sealing state on the inner wall, the space in the cavity is reduced in the downward moving process, so that internal liquid is extruded through the upper flow channel, and when the piston tip moves to the bottom of the body, the extrusion process is finished; external force is removed, and the pump head enters an absorption process; when the piston tip moves continuously and the channel hole of the piston tip is positioned at the piston shielding position, the upper flow channel is closed, the piston tip moves upwards continuously, the sealing shaft at the bottom of the piston tip is always positioned in the sealing hole of the body, the lower seal is also closed, the cavity is in a vacuum state, the piston tip moves upwards continuously, the resilience force of the spring is larger than the suction force of the vacuum state formed in the rising stage of the piston tip, the cavity is in the vacuum state continuously, when the piston tip moves upwards continuously and the gap is formed between the sealing shaft and the sealing hole, the vacuum state is broken, the cavity starts to absorb liquid in the bottle through the sealing hole, the piston tip moves upwards to the top, and when the pressure in the cavity is balanced, the liquid sucking process is finished and the next working cycle is waited.
As a preferred embodiment, the sealing shaft is in a cylindrical shape, and a chamfer part is arranged at the upper part of the wall of the sealing hole and has a guiding function on the sealing shaft. The chamfer portion enables the sealing shaft to have a guiding function in the early stage of insertion, and can ensure effective insertion of the sealing shaft into the sealing hole even when the direction of the component force due to pressing is not forward downward.
As a more preferable embodiment, the sealing shaft is in the shape of an upper section cylinder, the lower section is in the shape of a cone with gradually reduced diameter, the upper part of the wall of the sealing hole is provided with a chamfer part, and the lower section of the sealing shaft is inserted into the sealing hole at the lowest position. The sealing shaft with longer length is partially prolonged into the sealing hole, and due to the smaller outer diameter of the sealing shaft, reasonable clearance exists between the sealing shaft and the sealing hole, and liquid or paste can be sucked into the cavity during sucking.
As an improved embodiment, the spring replacement mounting position: the spring is installed in the body, the upper end face of the spring contacts with the piston tip, the lower end face of the spring contacts with the inner bottom of the body, and the bottom of the body is internally provided with a spring storage cavity, namely, the pump head adopting the inner spring structure can also implement the structure of the invention.
The upper sealing part is used as a functional structural part of the pump head, and a structure of adopting a fixed piston to be matched with a diaphragm type one-way valve also exists, and the structural part adopts other sealing forms without affecting the implementation of the invention.
The above disclosure is only a few specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be thought by those skilled in the art should fall within the protection scope of the present invention.
