Description

Technical Field

[0001] This invention belongs to the field of packaging bottle technology, specifically a pump head with a retractable nozzle. Background Technology

[0002] In many cases, liquid bottles are dispensed by opening the cap and pouring out the liquid. Some liquid bottles also have a pump head installed on the bottle body; pressing the pump head dispenses the liquid, preventing contamination and allowing for convenient metered dispensing. The shoulder sleeve is secured to the bottle body with threads or clips, and the pump head is directly fixed to the shoulder sleeve or clamped between the shoulder sleeve and the bottle body. Some liquid bottles may contain ingredients that should not come into contact with external objects, such as hair dye, cosmetics, and hair coloring solutions. After dispensing, some of this liquid may remain at the dispensing nozzle, requiring wiping after each use to prevent it from smearing other items. Therefore, a cap that elastically engages with the bottle body is usually located above the pump head. Users should tighten the cap before placing the pumped bottle in their bag, but the cap can still accidentally come loose inside the bag, posing a potential safety hazard. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a pump head with a retractable nozzle. This pump head allows the liquid outlet pipe to extend or retract from the top cover by rotating the top cover, thereby preventing liquid adhering to the second liquid outlet opening from coming into contact with other items.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a pump head with a retractable nozzle, comprising a bottle body, a shoulder sleeve, and a pump head body. The shoulder sleeve is fixed to the bottle body, and the pump head body is inserted through the shoulder sleeve. The suction port of the pump head body extends into the bottle body. The shoulder sleeve is provided with a guide portion, and a guide seat is movably mounted on the guide portion. A rotating head is rotatably inserted into the liquid outlet side of the pump head body. The guide seat is clamped between the rotating head and the side wall of the liquid outlet. A first liquid outlet channel is provided inside the rotating head. One end of the first liquid outlet channel is connected to the liquid outlet, and the other end of the first liquid outlet channel extends radially and is provided with a telescopic head. The telescopic head is provided with a second liquid outlet channel communicating with the first liquid outlet channel. The guide seat is provided with an arc-shaped guide groove extending from the near rotating head to the far rotating head. The telescopic head is provided with a guide slider extending into the arc-shaped guide groove. The top of the rotating head is provided with a rotating cover. The inner wall of the rotating cover is fixedly connected to the rotating head. The rotating cover has a cylindrical side wall, and the cylindrical side wall is provided with a through hole for the telescopic head to extend out. This type of pump head with a telescopic nozzle can drive the rotation of the rotating head by rotating the rotating cover. During the rotation of the rotating head, the rotating head drives the telescopic head to rotate. When the telescopic head rotates, since the guide slider can only slide within the arc-shaped guide groove, the telescopic head can extend or retract into the through hole, thereby preventing the liquid adhering to the second liquid outlet channel from contacting other items.

[0005] In the above technical solution, preferably, the shoulder sleeve sidewall is provided with a limiting strip, and the cylindrical sidewall is provided with a limiting protrusion lower than the top of the limiting strip. An avoidance opening for avoiding the limiting strip is provided on the side of the cylindrical sidewall adjacent to the limiting protrusion. The bottom of the cylindrical sidewall between the limiting protrusion and the avoidance opening is flush with the top of the limiting strip. When the limiting strip is aligned with the avoidance opening, the telescopic head extends out of the through hole. The limiting protrusion on the cylindrical sidewall can contact the limiting strip to determine its position when the rotating cover rotates. When the limiting protrusion contacts the limiting strip and the telescopic head extends out of the through hole, the limiting strip is aligned with the avoidance opening. Only then can the rotating cover be pressed down to squeeze out the liquid from the bottle. In other states, since the bottom of the cylindrical sidewall between the limiting protrusion and the avoidance opening is flush with the top of the limiting strip, it cannot be pressed down, thus effectively preventing accidental pressing and squeezing out of liquid.

[0006] In the above technical solution, preferably, the shoulder sleeve is provided with a first limiting ring, and the cylindrical sidewall is provided with a first limiting snap to prevent the rotating cover from detaching from the shoulder sleeve. The first limiting snap is located below the first limiting ring. This structure prevents the rotating cover from detaching from the shoulder sleeve when the telescopic head is retracted.

[0007] In the above technical solution, preferably, the shoulder sleeve includes a first shoulder piece and a second shoulder piece, which fasten together to form an annular groove. The limiting strip is disposed within the annular groove, and the cylindrical sidewall extends into the annular groove. This structure facilitates the processing of shoulder sleeves with complex shapes, and the formed annular groove can conceal the relatively complex cylindrical sidewall, resulting in a more aesthetically pleasing appearance.

[0008] In the above technical solution, preferably, the rotating cover is provided with a guide channel, and the telescopic head is movably disposed within the guide channel. This structure makes the extension and retraction of the telescopic head more stable.

[0009] In the above technical solution, preferably, the guide portion is cylindrical, with several vertical guide openings on its sidewall. An extension cylinder is provided at the bottom of the guide seat, and a barb extends outward from the extension cylinder. The barb is movably disposed within the vertical guide openings. The guide seat is pushed by the sidewall of the liquid outlet so that the barb hooks onto the upper edge of the vertical guide opening. This structure prevents the guide seat from detaching from the shoulder sleeve and allows the guide seat to move smoothly up and down within the guide portion.

[0010] In the above technical solution, preferably, limiting protrusions are provided on both sides of the bottle mouth on the bottle body, and a limiting groove is provided at the bottom of the shoulder sleeve. The limiting protrusions are inserted into the limiting groove, a second limiting ring is provided at the bottle mouth of the bottle body, and a second limiting snap is provided inside the shoulder sleeve. The second limiting ring passes through the shoulder sleeve and is limited by the second limiting snap. This structure prevents the bottle body and the shoulder sleeve from rotating relative to each other, avoiding accidental unscrewing of the bottle body and the shoulder sleeve when rotating the rotating cover.

[0011] Compared with the prior art, the present invention has the following advantages: the pump head with a retractable nozzle can drive the rotation of the rotating head by rotating the rotating cover. During the rotation of the rotating head, the rotating head drives the telescopic head to rotate. When the telescopic head rotates, since the guide slider can only slide in the arc-shaped guide groove, the telescopic head can be extended or retracted into the through hole, thereby avoiding the liquid adhering to the second liquid outlet opening from coming into contact with other items.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1 to 10A retractable nozzle pump head includes a bottle body 1, a shoulder sleeve 2, and a pump head body 3. The shoulder sleeve 2 is fixed to the bottle body 1, and the pump head body 3 is inserted through the shoulder sleeve 2. In this embodiment, the pump head body 3 is interference-fitted into the hole in the center of the shoulder sleeve 2, and the pump head body 3 is sandwiched between the shoulder sleeve 2 and the opening of the bottle body 1. The suction port of the pump head body 3 extends into the bottle body 1. The shoulder sleeve 2 is provided with a guide portion 211, and a guide seat 4 is provided on the guide portion 211 for lifting and lowering. A rotating head 32 is rotatably inserted into the outlet 31 side of the pump head body 3. The guide seat 4 is sandwiched between the rotating head 32 and the side wall of the outlet 31. A first outlet channel 33 is provided inside the rotating head 32, and one end of the first outlet channel 33 is connected to the outlet 31. Specifically, the guide seat 4 has a hole in the center for the pump head body 3 to pass through, and a positioning portion 44 extends inward from the inner wall of the hole. The positioning portion 44 is sandwiched between the rotating head 32 and the side wall of the outlet 31. The first liquid outlet channel 33 extends radially at the other end and is provided with a telescopic head 34. The telescopic head 34 can move back and forth along the direction of the first liquid outlet channel 33. The telescopic head 34 is provided with a second liquid outlet channel 35 that communicates with the first liquid outlet channel 33. The guide seat 4 is provided with an arc-shaped guide groove 41 extending from the near rotating head 32 to the far rotating head 32. The telescopic head 34 is provided with a guide slider 36 that extends into the arc-shaped guide groove 41. The top of the rotating head 32 is provided with a rotating cover 5. The inner wall of the rotating cover 5 is fixedly connected to the rotating head 32. Specifically, the inner wall of the rotating cover 5 is provided with a square positioning groove 57. The top of the rotating head 32 matches the shape of the square positioning groove 57 and is inserted into the square positioning groove 57. To further improve the positioning effect, a certain amount of glue can be added to the square positioning groove 57 for bonding. The rotating cover 5 has a cylindrical side wall 51. The cylindrical side wall 51 is provided with a through hole 52 for the telescopic head 34 to extend out. This type of retractable pump head can drive the rotation of the rotating head 32 by rotating the rotating cover 5. During the rotation of the rotating head 32, the rotating head 32 drives the telescopic head 34 to rotate. When the telescopic head 34 rotates, since the guide slider 36 can only slide in the arc-shaped guide groove 41, the telescopic head 34 can extend or retract into the through hole 52, thereby preventing the liquid adhering to the opening of the second liquid outlet channel 35 from coming into contact with other items.

[0023] The shoulder sleeve 2 has a limit strip 221 on its side wall, and a limit protrusion 53 on its cylindrical side wall 51 that is lower than the top of the limit strip 221. An avoidance opening 54 for avoiding the limit strip 221 is provided on the side of the cylindrical side wall 51 adjacent to the limit protrusion 53. The bottom of the cylindrical side wall 51 between the limit protrusion 53 and the avoidance opening 54 is flush with the top of the limit strip 221. When the limit strip 221 is aligned with the avoidance opening 54, the telescopic head 34 extends out of the through hole 52. In this embodiment, there are two sets of limit strips 221 in opposite positions inside the side wall of the shoulder sleeve 2. Similarly, there are two limit protrusions 53 in opposite positions on the cylindrical side wall 51. When the rotating cover 5 rotates, the limiting protrusion 53 on the cylindrical side wall 51 can contact the limiting strip 221 to determine its position. When the limiting protrusion 53 contacts the limiting strip 221 and the telescopic head 34 extends out of the through hole 52, the limiting strip 221 is aligned with the relief opening 54. Only when the rotating cover 5 is pressed can it be pressed down to squeeze out the liquid in the bottle 1. In other states, since the bottom of the cylindrical side wall 51 between the limiting protrusion 53 and the relief opening 54 is flush with the top of the limiting strip 221, it cannot be pressed down, thus effectively preventing accidental pressing and squeezing out of the liquid.

[0024] In this embodiment, a first limiting ring 214 is provided on the shoulder sleeve 2, and a first limiting snap 55 is provided on the cylindrical side wall 51 to prevent the rotating cover 5 from detaching from the shoulder sleeve 2. The first limiting snap 55 is located below the first limiting ring 214 and is an arc-shaped protrusion along the inner wall of the cylindrical side wall 51. Two first limiting snaps 55 are provided on opposite sides of the cylindrical side wall 51. This structure prevents the rotating cover 5 from detaching from the shoulder sleeve 2 when the telescopic head 34 is retracted.

[0025] In this embodiment, the shoulder sleeve 2 includes a first shoulder piece 21 and a second shoulder piece 22. The first shoulder piece 21 and the second shoulder piece 22 are fastened together to form an annular groove 23. A limiting strip 221 is disposed in the annular groove 23, and a cylindrical sidewall 51 extends into the annular groove 23. This structure facilitates the processing of shoulder sleeves with complex shapes, and the formed annular groove 23 can cover the relatively complex cylindrical sidewall 51, making the appearance more aesthetically pleasing.

[0026] In this embodiment, a guide channel 56 is provided on the rotating cover 5, and the telescopic head 34 is movably disposed within the guide channel 56. This structure makes the extension and retraction of the telescopic head 34 more stable.

[0027] In this embodiment, the guide portion 211 is cylindrical, and its sidewall is provided with several vertical guide openings 212. An extension cylinder 42 is provided at the bottom of the guide seat 4, and barbs 43 extend outward from the extension cylinder 42. The barbs 43 are movably disposed within the vertical guide openings 212. The guide seat 4 is pushed by the sidewall of the liquid outlet 31 so that the barbs 43 hook onto the upper edge of the vertical guide openings 212. Specifically, the sidewall of the guide portion 211 is provided with four evenly distributed vertical guide openings 212, and the outer periphery of the extension cylinder 42 is provided with four barbs 43.

[0028] In this embodiment, limiting protrusions 11 are provided on both sides of the bottle mouth on the bottle body 1, and limiting grooves 24 are provided at the bottom of the shoulder sleeve 2. Specifically, both the first shoulder sleeve 21 and the second shoulder sleeve 22 are provided with limiting grooves 24. The limiting protrusions 11 are inserted into the limiting grooves 24. A second limiting ring 12 is provided at the bottle mouth of the bottle body 1, and a second limiting snap 213 is provided inside the shoulder sleeve 2. The second limiting ring 12 passes through the shoulder sleeve 2 and is limited by the second limiting snap 213. This structure prevents the bottle body 1 and the shoulder sleeve 2 from rotating relative to each other, avoiding accidental unscrewing of the bottle body 1 and the shoulder sleeve 2 when rotating the rotating cover 5.

[0029] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
