As shown in fig. 1-2, a liquid outlet structure for a laundry detergent bottle cap comprises a main body 100 and a pressing pipe 200, wherein a first cavity 110 is arranged at the bottom of the main body 100, the first cavity 110 is used for communicating with a laundry detergent bottle body, a piston 500 is arranged in the first cavity 110, and a spring 600 is arranged on one side of the piston 500.

The pressing tube 200 includes an inlet end and an outlet end, the inlet end penetrates through the piston 500 along the axis of the piston 500, the pressing tube 200 can slide along the axis of the main body 100, and the sliding pressing tube 200 presses the piston 500 to draw the laundry detergent; the outlet end is connected with a liquid outlet head 400, a liquid outlet channel 410 is arranged in the liquid outlet head 400, and the flow area of the liquid outlet channel 410 is gradually reduced from one side close to the outlet end to one side far away from the outlet end.

More specifically, in practical applications, the main body 100 may be installed at the laundry detergent bottle mouth by a screw connection. The axis of the pressing tube 200 coincides with the axis of the main body 100. After the main body 100 is mounted on the washing liquid bottle, the pressing tube 200 should be in a vertical state. In a more specific embodiment, both the body 100 and the pressing tube 200 may be made of plastic. More specifically, the pressing tube 200 slides in the body 100 along the axis of the body 100, which is the same as the structure of the conventional press-type bottle cap, and thus, the matching relationship between the pressing tube 200 and the body 100 is not described in detail in this application.

The specific process of using the liquid outlet structure is as follows: an extension pipe is connected to the inlet end of the pressing pipe 200, and the extension pipe extends into the bottom of the laundry detergent bottle body after the main body 100 is fixed on the laundry detergent bottle opening. When the washing liquid bottle is used, a consumer presses the pressing pipe 200 from top to bottom, the pressing pipe 200 slides and presses the piston 500, and therefore the washing liquid in the washing liquid bottle enters the pressing pipe 200 through the extension pipe. The pressed piston 500 is reset by the spring 600, which also drives the pressing tube 200 to reset. After entering the pressing tube 200, the laundry detergent enters the liquid outlet head 400 under the action of air pressure, and due to the special structure of the liquid outlet channel 410 of the liquid outlet head 400, the flow rate of the laundry detergent in the liquid outlet head 400 is increased, and the laundry detergent is rapidly extruded and does not remain in the liquid outlet head 400.

The liquid outlet structure for the laundry detergent bottle cap comprises a main body 100 and a pressing pipe 200, wherein a first cavity 110 for communicating with a laundry detergent bottle body is arranged at the bottom of the main body 100, and a piston 500 is arranged in the first cavity 110; the inlet end of the pressing pipe 200 penetrates through the piston 500, the pressing pipe 200 presses the piston 500 to extract the laundry detergent, and the laundry detergent enters the pressing pipe 200 from the inlet end of the pressing pipe 200 and enters the liquid outlet head 400 from the outlet end. Because the flow area of the liquid outlet channel 410 of the liquid outlet head 400 gradually decreases from the side close to the outlet end to the side far away from the outlet end, the pressure of the laundry detergent in the liquid outlet channel 410 increases, the flow rate of the laundry detergent becomes fast, and the laundry detergent is not easy to remain at the liquid outlet head 400 after being extruded, so that the laundry detergent is avoided being wasted, the laundry detergent can be prevented from polluting hands of users, and the happiness of the users when using the laundry detergent is improved. Further, the liquid outlet channel 410 comprises a first transition pipe 4101 and a second transition pipe 4102 which are connected in sequence, and one end of the first transition pipe 4101 is communicated with the outlet end of the pressing pipe 200.

In a more specific embodiment, the length of the first transition tube 4101 is greater than the length of the second transition tube 4102. In the flow direction of the liquid, the maximum flow area of the second transition pipe 4102 is smaller than half of the maximum flow area of the first transition pipe 4101. The first transition pipe 4101 has a long length to ensure that the flow rate of the laundry detergent in the first transition pipe 4101 can be quickly increased, and the second transition pipe 4102 has a small flow area to ensure that the speed of the extruded laundry detergent in the second transition pipe 4102 is changed quickly and increased quickly, so that the laundry detergent is not easy to remain.

Further, the liquid outlet head 400 is in threaded connection with the pressing pipe 200. Go out liquid head 400 with through threaded connection between the pressure pipe 200, easy dismounting can dismantle the cleanness in long-term use moreover, guarantees go out liquid head 400 clean health.

Further, a stop ring 210 is arranged on the pressing pipe 200, the stop ring 210 is located in the first cavity 110, and the sliding pressing pipe 200 presses the piston 500 through the stop ring 210. The pressing pipe 200 passes through the piston 500, and the side wall of the stopper ring 210 is in contact with the side wall of the piston 500, so that the sliding pressing pipe 200 can press and press the piston 500 through the stopper ring 210. In other embodiments, the retainer ring 210 may also be a protrusion disposed on the sidewall of the pressing tube 200.

Further, a limiting ring 220 is arranged on the pressing pipe 200, the limiting ring 220 is sleeved on the pressing pipe 200 and is located between the piston 500 and the main body 100, and the limiting ring 220 is movably arranged on the pressing pipe 200 and is used for limiting the sliding stroke of the pressing pipe 200. The stop collar 220 and the side wall of the pressing tube 200 can be matched through threads, so that the position of the stop collar 220 on the pressing tube 200 can be adjusted by turning the stop collar 220. By changing the position of the stopper ring 220, the sliding stroke of the pressing pipe 200 when pressed, that is, the degree of pressing of the piston 500, can be changed, and thus the amount of the laundry detergent sucked into the pressing pipe 200 per pressing can be changed.

The main body 100 is provided with a guide post 300 for guiding the pressing pipe 200 to slide. The axis of the guide post 300 coincides with the axis of the main body 100, and the guide post 300 is arranged at the top of the main body 100, and is used for limiting the pressing pipe 200 and guiding the sliding of the pressing pipe 200.
