Description

Technical Field

[0001] The utility model relates to the technical field of daily chemical hoses, in particular to an anti-clogging daily chemical hose structure. Background Art

[0002] Daily chemical hoses play an indispensable role in daily life. As an important packaging form for daily chemical products, they have many advantages. Their tough material can effectively protect the contents and ensure the safety of the products during transportation and use. At the same time, the hoses are exquisitely designed, which allows consumers to accurately control the amount of use and improve the user experience. Whether it is cosmetics, skin care products, or cleaning products, daily chemical hoses provide convenient, safe and beautiful packaging options, promoting the continuous development of the daily chemical industry.

[0003] For example, the Chinese patent with publication number CN219030340U discloses a daily chemical hose structure that prevents clogging, which relates to the field of hose packaging. Aiming at the problem that the existing hose packaging has poor sealing performance, which causes the product at the pipe mouth to harden and clump easily, the following scheme is proposed, which includes a hose, the top of which is provided with a pipe mouth, and the pipe mouth is threadedly sleeved with an inner cover, the inner cover is outer-sleeved with an outer cover, and a sealing structure is provided between the pipe mouth and the inner cover and the outer cover, and the sealing structure: the top of the pipe mouth is sleeved with an annular bracket, the top of the annular bracket is sleeved with a rubber cover, and the top of the rubber cover is in the shape of a dome, the top of the rubber cover is provided with a slit, and the outer side of the rubber cover is provided with a first side strip, and the top of the inner cover is provided with a circular hole to be sleeved with the rubber cover arch. The utility model has a novel structure, and the device effectively solves the problem that the existing hose packaging has poor sealing performance, which causes the product at the pipe mouth to harden and clump easily.

[0004] Although the above example can enhance the sealing of the daily chemical hose by setting a rubber cover to prevent the hardening of cosmetics at the extrusion outlet of the daily chemical hose, existing daily chemical hoses are mostly made of PET and other materials with a certain elasticity. After extrusion, the daily chemical hose will rebound, and then the outside air will be sucked into the daily chemical hose, causing the cosmetics in the daily chemical hose to harden, which is inconvenient to use.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the embodiments:

[0024] Example 1

[0025] like Figure 1-5 As shown, the utility model provides an anti-clogging daily chemical hose structure, including a tube body 1, the bottom of the tube body 1 is fixedly connected with an extrusion mechanism 2, the top of the tube body 1 is fixedly connected with a sealing mechanism 3, the tube body 1 includes a daily chemical hose 11, both sides of the inner cavity of the daily chemical hose 11 are fixedly connected with guide ridges 12, the inner wall of the daily chemical hose 11 is slidably connected with a piston 13, the top of the piston 13 is provided with an arc, the surface of the piston 13 is meshed with the surface of the guide ridge 12, the top of the daily chemical hose 11 is fixedly connected with an extrusion port 14, the top of the inner cavity of the daily chemical hose 11 is provided with an arc, and the arc of the top of the piston 13 is consistent with the arc of the top of the inner cavity of the daily chemical hose 11.

[0026] In this embodiment, by manually squeezing the squeezing tube 21, the piston 13 is pushed to slide along the guide ridge 12 under the action of the air pressure in the squeezing tube 21, and the cosmetics in the daily chemical hose 11 are pushed toward the extrusion port 14. Under the action of the thrust of the cosmetics, the top of the inner cavity of the sealing plug 35 bulges upward, the cross notch 36 is enlarged, and the cosmetics can be squeezed out for use.

[0027] Example 2

[0028] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the extrusion mechanism 2 includes an extrusion tube 21, the top of the extrusion tube 21 is fixedly connected to the bottom of the daily chemical hose 11, the bottom of the inner cavity of the extrusion tube 21 is fixedly connected with a ventilation tube 22, a through hole 23 is opened inside the ventilation tube 22, one end of the inner cavity of the through hole 23 is stamped to form a protrusion 231, the bottom of the inner cavity of the through hole 23 is overlapped with a sealing ball 24, the top of the sealing ball 24 is overlapped with a spring 25, and the top of the spring 25 overlaps with the surface of the protrusion 231.

[0029] In this embodiment, through the Panasonic squeeze tube 21, due to the rebound of the squeeze tube 21, the air pressure in the squeeze tube 21 is lower than the normal external air pressure. Under the action of the air pressure, the sealing ball 24 pushes the spring 25 to contract, and the external air flow can enter the squeeze tube 21 along the through hole 23, so that the entering air does not contact the cosmetics, avoiding the hardening of the cosmetics and causing the extrusion port 14 to be blocked, making it more convenient to use.

[0030] Example 3

[0031] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the sealing mechanism 3 includes a fixing ring 31, the bottom of the fixing ring 31 is fixedly connected to the top of the daily chemical hose 11, the top of the fixing ring 31 is fixedly connected with a sealing ring 32, the surface of the sealing ring 32 is interference-connected with a clamping ring 34, the surface of the clamping ring 34 is fixedly connected with a sealing cover 33, the inside of the extrusion port 14 is plugged with a sealing plug 35, the top of the inner cavity of the sealing plug 35 is provided with a cross notch 36, the surface of the extrusion port 14 is threadedly connected with a fixing sleeve 37, the top of the inner cavity of the fixing sleeve 37 overlaps with the surface of the sealing plug 35, and the surface of the fixing sleeve 37 is interference-connected with a sealing cover 38.

[0032] In this embodiment, by setting the sealing plug 35 and the cross notch 36, the cross notch 36 is in a closed state under normal conditions to prevent the cosmetics from contacting with the outside air. The sealing cover 38 with interference fit on the surface of the fixed sleeve 37 can perform the initial sealing of the sealing plug 35, and at the same time, it can prevent the cosmetics from spraying out when the squeezing tube 21 is squeezed by mistake. The setting of the sealing cover 33 can perform secondary sealing on the daily chemical hose to achieve a better sealing effect.

[0033] The working principle of the anti-clogging daily chemical hose structure is described in detail below.

[0034] like Figure 1-5As shown, when in use, the squeezing tube 21 is squeezed manually. Under the action of the air pressure in the squeezing tube 21, the piston 13 is pushed to slide along the guide convex strip 12, and the cosmetics in the daily chemical hose 11 are pushed to the extrusion port 14. Under the action of the thrust of the cosmetics, the top of the inner cavity of the sealing plug 35 bulges upward, and the cross notch 36 expands, and the cosmetics can be squeezed out for use. Then, the squeezing tube 21 is released. Under the action of the rebound of the squeezing tube 21, the air pressure in the squeezing tube 21 is lower than the normal air pressure outside. Under the action of the air pressure, the sealing ball 24 pushes the spring 25 to contract, and the external airflow can be discharged along the passage. The hole 23 enters the extrusion tube 21, so that the air entering does not contact the cosmetics, and the cosmetics are prevented from hardening and causing the extrusion port 14 to be blocked, making it easier to use. At the same time, the sealing plug 35 and the cross notch 36 are set. The cross notch 36 is in a closed state under normal conditions to prevent the cosmetics from contacting the outside air. The sealing cover 38 with interference fit on the surface of the fixing sleeve 37 can perform the initial sealing of the sealing plug 35, and at the same time, it can prevent the cosmetics from spraying out when the extrusion tube 21 is squeezed by mistake. The setting of the sealing cover 33 can perform secondary sealing on the daily chemical hose, so that its sealing effect is better.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
