Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spray heads, in particular to a throttling structure of a spray head valve core. Background Technique
[0002] In the field of spray technology, the performance of a spray head is directly related to the uniformity, efficiency and user experience of spraying. The traditional opening methods of spray head valve cores mostly rely on mechanical structures such as springs and levers, and these methods have certain limitations in terms of response speed, precise control and durability. Especially in scenarios where rapid response or precise control of the spray volume is required, the traditional mechanical valve core opening methods are difficult to meet the requirements. Therefore, we propose a throttling structure of a spray head valve core, which adopts a pneumatic method to open the valve core. Content of the Utility Model

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A throttling structure of a spray head valve core, including a spray head, further including:
[0005] A valve cavity, an air passage, and a flow passage, the valve cavity, the air passage, and the flow passage are all arranged inside the spray head, and the valve cavity, the air passage, and the flow passage are connected and communicated;
[0006] A piston, the piston moves inside the valve cavity, and a valve rod is connected to the bottom end of the piston;
[0007] A valve body, the valve body is installed in a section of the flow passage, several diversion holes are arranged at the edge of the valve body, and the valve rod plugs the diversion holes.
[0008] Further, a lower limit groove is reserved at the top end of the piston, and a limit convex column is connected to the middle of the lower limit groove.
[0009] Further, a fastening seat is arranged at the upper part of the valve body, and the fastening seat is connected to the inside of the valve cavity by threads.
[0010] Further, through holes are reserved inside the fastening seat and the valve body, the through holes are communicated with the diversion holes, and the valve rod is inserted into the through holes.

[0013] The utility model provides a throttling structure for a spray head valve core. Compared with the prior art, it has the following beneficial effects:
[0014] In this throttling structure of the spray head valve core, a valve cavity, an air passage, and a flow passage that are connected to each other are respectively arranged inside the spray head. The valve core is installed in the valve cavity. When it is necessary to open the flow passage to allow the fluid to flow through, gas is first injected into the air passage. The gas generates air pressure to push the piston of the valve core upward. After the valve stem disengages from the valve body, the fluid passes through the flow passage where the valve body is located. When throttling is required, the pressure generated by the gas is cancelled, and the spring can push the piston to reset to throttle the flow passage. Compared with other opening and closing methods, this method is more convenient and effective. Description of the Drawings

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-5, the present utility model provides a technical solution: a throttling structure of a spray head valve core, including a spray head 1, a valve cavity 2, an air passage 3, a flow passage 4, a piston 5, a valve body 6, a cover plate 7 and a spring 8. Among them, the spray head 1 is the main body of the entire structure, integrating key components such as the valve cavity 2, the air passage 3, and the flow passage 4. The valve cavity 2, the air passage 3, and the flow passage 4 are connected. The valve cavity 2 is located inside the spray head 1 and is used to accommodate the piston 5 and its related components. It is the main space for the movement of the valve core. The air passage 3 connects the external air source and the valve cavity, and controls the movement of the piston by injecting gas. The flow passage 4 is the flow path of liquid or gas, and its smoothness is controlled by the diversion holes 61 on the valve body 6. It moves inside the valve cavity and controls the opening and closing of the diversion holes on the valve body 6 through its up and down movement. The valve stem 51 at the bottom of the piston directly acts on the diversion holes, and the bottom of the piston 5 is connected with a valve stem 51. The valve body 6 is installed in the section of the flow passage 4, and several diversion holes 61 are provided at the edge of the valve body 6. The valve stem 51 blocks the diversion holes 61. A lower limit groove 52 is reserved at the top of the piston 5, and a limit convex column 53 is connected in the middle of the lower limit groove 52. An upper fastening seat 62 is provided on the upper part of the valve body 6 (the valve body 6 and the fastening seat 62 are of a split structure. In the industry, this structure is generally made into an integral structure. After any one of the valve body 6 or the fastening seat 62 is worn or damaged, the whole needs to be replaced. However, for the split structure, only the damaged one needs to be repaired or replaced. During installation, first place the valve body 6 in the valve cavity 2, and then thread the fastening seat 62 into the valve cavity 2 to press down and fix the valve body 6), the fastening seat 62 is connected to the inside of the valve cavity 2 by threads. Through holes are reserved inside the fastening seat 62 and the valve body 6, and the through holes are communicated with the diversion holes 61. The valve stem 51 is inserted into the through holes. The top of the spray head 1 is connected with a cover plate 7, and an upper limit groove 71 is reserved inside the cover plate 7 (the upper and lower limit grooves serve as the support points of the spring 8 to ensure the piston is stable at a specific position). A spring 8 is jointly abutted between the upper limit groove 71 and the lower limit groove 52, and the spring 8 is sleeved outside the limit convex column 53.
[0023] When using this throttling structure of the spray head valve core, when it is necessary to start spraying, external gas is injected into the valve cavity 2 through the air passage 3, pushing the piston 5 to move upward. The valve stem 51 of the piston rises accordingly and no longer blocks the diversion holes 61 on the valve body 6, so that the flow passage 4 is unblocked, allowing liquid or gas to spray out. At the same time, the spring 8 is compressed and stores potential energy. When the gas injection stops or the gas pressure decreases, the spring 8 releases energy, pushing the piston 5 to move downward, and the valve stem 51 blocks the diversion holes 61 again to achieve throttling.
