Description

Technical Field

[0001] The invention belongs to the technical field of pump head structures, and in particular relates to the structure of a daily chemical bottle pump head. Background Art

[0002] Daily chemical products, such as shampoo, shower gel, skin care products and other daily chemical liquids, are indispensable personal care products in daily life. These products are usually sold in bottled form and are equipped with pump heads for users to use. The pump head serves as a bridge between the liquid in the bottle and the user, and its design directly affects the product's user experience, hygiene and liquid utilization efficiency. Traditional daily chemical bottle pump heads have certain defects when used. For example, in a Chinese patent with publication number "CN 116636764 B", a liquid pump head for a soap dispenser is disclosed, including a storage tank body and a sealing cover, the top of the storage tank body is threadedly provided with a sealing cover, and the top of the sealing cover is provided with a docking shell, the interior of the docking shell is provided with a connecting column, and the end of the connecting column is provided with a pump head body. For example, in a Chinese patent with publication number "CN 116636764 B", a liquid pump head for a soap dispenser is disclosed, including a storage tank body and a sealing cover, the top of the storage tank body is threadedly provided with a sealing cover, and the top of the sealing cover is provided with a docking shell, the interior of the docking shell is provided with a connecting column, and the end of the connecting column is provided with a pump head body. 220885403U" discloses a pump head assembly and a container, wherein the pump head assembly comprises a cover body, a pump body and a pressing assembly, wherein the cover body is arranged at the container mouth, and the pump body is connected to the cover body; the pressing assembly comprises a pressing head, a pressing rod and a liquid outlet pipe, wherein the pressing head is hinged to the cover body; the pressing rod is hollow to form a liquid outlet channel, and the pressing rod is arranged on the cover body, wherein the first end of the pressing rod abuts against the side wall of the pressing head facing the cover body, and the second end of the pressing rod is connected to the pump body. Although both of the above two devices can achieve the purpose of extracting liquid, the device extracts liquid in a manner that is not suitable for the purpose of extracting liquid. The structure is an integrated assembly, so after damage, all structures need to be replaced as a whole, increasing the cost of use. In addition, the discharge volume of the device when extracting liquid cannot be discharged at a fixed rate.

[0017] (3) The present invention provides a connecting head and a conical rubber membrane. When a person connects the connecting head to the connecting tube, the connecting head squeezes the conical rubber membrane, thereby allowing the conical rubber membrane to open, so that the daily chemical liquid can be normally transported to the inside of the storage shell. When the person separates the connecting head from the liquid guide tube, the conical rubber membrane closes, so that when the person carries the storage shell, the daily chemical liquid is prevented from accidentally leaking, thereby improving the efficiency of the person carrying the daily chemical liquid.

[0018] (4) Before pressing the pressure plate and the piston rod, the present invention rotates the connecting ring and cooperates with the external thread on the piston rod to adjust the position of the connecting ring on the piston rod. The connecting ring limits the maximum movement distance of the piston rod to avoid excessive squeezing when people take daily chemical liquids, avoid waste, and reduce the cost of use.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 12 As shown, the present invention provides the following technical solutions:

[0034] A structure of a daily chemical bottle pump head, in order to facilitate the replacement of the structure later when it is used, without the need for overall replacement, the structure comprises a shell member 3 detachably connected to the daily chemical bottle;

[0035] Furthermore, in the present invention, in order to extract the liquid in the daily chemical bottle, a pump body part 2 for extracting the liquid is installed on the housing part 3;

[0036] In addition, in the present invention, in order to allow the mechanism to be replaced, the housing member 3 includes a connecting portion connected to the daily chemical bottle and a conveying portion for conveying liquid;

[0037] A delivery channel for delivering liquid along a preset path is formed inside the delivery part, part of the pump body 2 is located inside the delivery channel, and the connecting part includes a baffle 34 and a connecting cover 38, the baffle 34 is sleeved on the delivery part, and the connecting cover 38 is provided with a slot 39 for the delivery part to pass through, the baffle 34 is located below the slot 39, and a detachable connecting ring 37 is screwed and connected to the delivery part, and the connecting ring 37 is located above the slot 39.

[0038] Through the above technical solution, when a person needs to use the device, the daily chemical liquid to be used is added to the daily chemical bottle. After the daily chemical liquid is added, the structure is placed above the daily chemical bottle, and is screwed and connected to the daily chemical bottle through the connecting cover 38, so that the structure is connected to the daily chemical bottle. When a person needs to extract the daily chemical liquid, the pump body 2 works to extract the daily chemical liquid, so that the daily chemical liquid in the daily chemical bottle is transported to the inside of the transport part, and the daily chemical liquid is guided to flow through the transport channel inside the transport part. Finally, the daily chemical liquid is discharged through the liquid outlet end of the transport part, so that the person can use it easily. In addition, when the pump body 2 is damaged, it is only necessary to rotate the connecting cover 38 to separate the connecting cover 38 from the daily chemical bottle, pull the connecting cover 38 to separate the device from the daily chemical bottle, pull the pump body 2 and the conveying part to move, so that the pump body 2 and the conveying part are separated from the connecting cover 38, and then insert the intact conveying part and the pump body 2 into the slot 39 on the connecting cover 38, and use the baffle 34 on the conveying part to contact the bottom end of the connecting cover 38, and then screw the connecting ring 37 with the conveying part to complete the replacement of the pump body 2, so that the device does not need to be replaced as a whole when it is damaged.

[0039] In addition, in the present invention, when personnel are in some special usage scenarios, they need to carry a small amount of daily chemical liquid with them for use at any time. In order to facilitate the personnel to carry a small amount of daily chemical liquid and improve the convenience of personnel when using it, there is no need to store it through other equipment, such as Figure 1-Figure 3 As shown, the liquid outlet end of the pump body 2 is fixedly connected with a connector 212, one end of the connector 212 is screwed and connected with a detachable frothing piece 1, a cavity for accommodating liquid is formed inside the frothing piece 1, and a liquid outlet head 18 for discharging liquid is arranged at the bottom of the frothing piece 1, a valve 19 is installed on the liquid outlet head 18, and the liquid outlet head 18, the connector 212 and the cavity are connected.

[0040] In the present embodiment, before the personnel take the daily chemical liquid, the personnel connect the foaming piece 1 with the connecting head 212, thereby connecting the foaming piece 1 with the pump body part 2. When the personnel extract the daily chemical liquid through the pump body part 2, the daily chemical liquid is transported to the cavity inside the foaming piece 1 through the connecting head 212. When the daily chemical liquid fills the cavity, as the personnel continue to use the pump body part 2, the daily chemical liquid is discharged through the liquid outlet head 18, thereby making it convenient for the personnel to take the daily chemical liquid. When the personnel needs to carry a small amount of daily chemical liquid, the personnel rotate the foaming piece 1 to separate the foaming piece 1 from the connecting head 212, close the valve 19, and the personnel can carry the foaming piece 1 to move, thereby making it convenient for the personnel to carry a small amount of daily chemical liquid without the need to store the daily chemical liquid through other equipment. Moreover, since there is no need to store the daily chemical liquid through other equipment, contamination of the daily chemical liquid during the transfer process is avoided.

[0041] Specifically, in one embodiment, regarding the above-mentioned foaming member 1, as Figure 9-12As shown, the foaming element 1 includes a storage shell 12, the top of the storage shell 12 is rotatably connected to a cover plate 11, a cavity is formed between the cover plate 11 and the storage shell 12, a liquid outlet head 18 is fixedly connected to the bottom of the storage shell 12, and a connecting tube 13 is fixedly connected to one side of the storage shell 12, and the connecting tube 13 is screwed together with the connecting head 212.

[0042] In this embodiment, the storage shell 12 is connected to the connector 212 through the connecting pipe 13, so that the storage shell 12 is connected to the pump body 2. When a person extracts daily chemical liquid through the pump body 2, the daily chemical liquid is transported to the cavity between the storage shell 12 and the cover plate 11 through the connector 212. When the daily chemical liquid fills the cavity, as the person continues to use the pump body 2, the daily chemical liquid is discharged through the liquid outlet 18, so that the person can easily take the daily chemical liquid. When the person needs to carry a small amount of daily chemical liquid, the storage shell 12 is rotated. The storage shell 12 is stored, so that the storage shell 12 is separated from the connecting head 212, and the valve 19 is closed. The personnel can carry the storage shell 12 and the cover plate 11 to move, so that the personnel can carry a small amount of daily chemical liquid conveniently without the need to store the daily chemical liquid through other equipment. In addition, since there is no need to store the daily chemical liquid through other equipment, the contamination of the daily chemical liquid during the transfer process is avoided. When the personnel need to take the daily chemical liquid in the cavity, the cover plate 11 is pulled to separate the cover plate 11 from the storage shell 12, and the daily chemical liquid in the storage shell 12 can be taken out.

[0043] Furthermore, in the present invention, since the storage shell 12 can be disassembled and carried separately, when a person carries the storage shell 12 separately for use, in order to facilitate automatic sealing of the connecting tube 13, as shown in FIG. Figure 10-12 As shown, a conical rubber membrane 17 is bonded inside the connecting tube 13 , and the conical rubber membrane 17 gradually decreases from one side close to the connecting head 212 to the other side.

[0044] In this embodiment, when the connecting tube 13 is connected to the connecting head 212, the conical rubber membrane 17 is squeezed by the connecting head 212, so that the conical rubber membrane 17 is opened. When the connecting head 212 discharges the daily chemical liquid, the daily chemical liquid is transported to the inside of the storage shell 12 through the conical rubber membrane 17 and the connecting tube 13. When a person separates the storage shell 12 from the connecting head 212, the conical rubber membrane 17 automatically closes, so that there will be no accidental leakage when the person carries the storage shell 12 and the cover plate 11 to move.

[0045] Furthermore, when the cover 11 is closed, in order to prevent the cover 11 from being accidentally opened, thereby reducing the probability of leakage of the liquid inside the storage shell 12, as shown in FIG. Figure 10-12 As shown, a buckle 14 is fixedly connected to one side of the cover plate 11 , and a slot 15 matching the buckle 14 is opened on one side of the storage shell 12 , and a groove 16 is formed inwardly at the top of the cover plate 11 .

[0046] In this embodiment, when a person closes the cover 11, the buckle 14 on the cover 11 engages with the slot 15 on the storage shell 12, so that the cover 11 is more secure after being closed. When a person needs to pull the cover 11, the pull slot 16 makes it easier to pull the cover 11.

[0047] In addition, in the present invention, how the liquid outlet head 18 generates foam, such as Figure 8 As shown, a frothing net 110 is fixedly connected to the inside of the liquid outlet head 18 , and the frothing net 110 is located below the valve 19 .

[0048] In this embodiment, when the daily chemical liquid is discharged through the liquid outlet head 18, it cooperates with the foaming net 110 so that the daily chemical liquid forms foam when it is discharged, making it easy for people to take it.

[0049] Specifically, in one embodiment, regarding the above-mentioned conveying part, as Figure 1-Figure 5 As shown, the conveying part includes a shell 33, a liquid extraction tube 31 is fixedly connected to the bottom of the shell 33, a baffle 34 is fixedly connected to the circumference of the shell 33, and the top of the baffle 34 is sunken to form a limiting groove 36, and a sealing ring 35 is bonded inside the limiting groove 36.

[0050] In this embodiment, when a person needs to use the device, the daily chemical liquid to be used is added to the daily chemical bottle. After the daily chemical liquid is added, the liquid extraction tube 31 is placed above the daily chemical bottle, and the liquid extraction tube 31 is inserted into the daily chemical bottle, and the connecting cover 38 is screwed together with the daily chemical bottle, so that the liquid extraction tube 31 and the shell 33 are inside the daily chemical bottle. When a person needs to extract the daily chemical liquid, the pump body 2 works to extract the daily chemical liquid for output.

[0051] In addition, in the present invention, how the pump body 2 extracts the daily chemical liquid, such as Figure 1-Figure 5 As shown, the pump body 2 includes a first sealing bead 21, and a conical cover 23, a spring 24 and a piston rod 25 are arranged above the first sealing bead 21 in sequence from bottom to top, and the first sealing bead 21, the conical cover 23, the spring 24 and the piston rod 25 are all located inside the shell 33, and a sealing cover 213 is also bonded to the top of the shell 33, the spring 24 is located between the sealing cover 213 and the conical cover 23, and a through-type through hole 22 is opened on the conical cover 23, the top of the piston rod 25 extends to the outside of the shell 33, and the top of the piston rod 25 is fixedly connected to a liquid guide tube 211 connected to the inside of itself, the liquid outlet end of the liquid guide tube 211 is fixedly connected to the connector 212, and the top of the liquid guide tube 211 is fixedly connected to a pressure plate 210, a second sealing bead 28 is installed between the inside of the piston rod 25 and the inside of the liquid guide tube 211, and a limiting rod 29 is fixedly connected to the inside of the liquid guide tube 211, and the limiting rod 29 is located above the second sealing bead 28.

[0052] In this embodiment, when the liquid extraction tube 31 and the shell 33 are inside the daily chemical bottle, if the personnel needs to extract liquid, the personnel presses the pressure plate 210, so that the pressure plate 210 drives the liquid guide tube 211 to move, and then the piston rod 25 moves downward. When the piston rod 25 moves downward, the spring 24 will be compressed and the second sealing bead 28 will fall downward. After the personnel releases the pressure plate 210, the spring 24 rebounds, thereby pushing the piston rod 25 to move back and exhausting the air inside the shell 33, making the shell 33 negative pressure. Therefore, the first sealing bead 21 is lifted up by the liquid in the daily chemical bottle and transported to the inside of the shell 33 through the through hole 22 on the conical cover 23. The personnel repeat the above process until the daily chemical liquid fills the shell 33. Finally, the daily chemical liquid is discharged through the liquid guide tube 211, and then transported to the inside of the storage shell 12 through the connecting head 212, and finally discharged through the liquid outlet head 18.

[0053] When personnel take daily chemical liquid, in order to discharge it quantitatively, to avoid excessive daily chemical liquid being wasted by personnel pumping out, such as Figure 1-Figure 5 As shown, the outer circumference of the piston rod 25 is indented to form an external thread 26 , and a limit ring 27 is screwed on the circumference of the piston rod 25 , and the limit ring 27 is located above the housing 33 .

[0054] In this embodiment, before a person presses the pressure plate 210, the limit ring 27 is rotated, and the limit ring 27 is moved relative to the piston rod 25 through the external thread 26, thereby adjusting the position of the limit ring 27 on the piston rod 25. When a person presses the pressure plate 210, the limit ring 27 limits the maximum movement distance of the piston rod 25, thereby limiting the discharge amount of the daily chemical liquid, making it easier for the person to take the daily chemical liquid and avoiding squeezing out too much liquid.

[0055] In addition, when personnel use this structure, in order to allow the structure to be adjusted according to the depth of the daily chemical bottle, such as Figure 1-Figure 3 , Figure 8 As shown, the bottom of the liquid extraction tube 31 is fixedly connected to a limit plate 32 , and a movable extension tube 310 is sleeved on the liquid extraction tube 31 , and a filter screen 311 is fixedly connected to the bottom of the extension tube 310 .

[0056] In this embodiment, before the personnel connects the device to the daily chemical bottle, they pull the extension tube 310 to move relative to the liquid extraction tube 31, thereby adjusting the extension length of the liquid extraction tube 31, making it easy to adjust the device according to the length of the daily chemical bottle, and when extracting the daily chemical liquid, the daily chemical liquid is filtered through the filter 311.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
