[0034] Figure 1 It is a three-dimensional diagram of an embodiment of the utility model, referring to Figure 1 One embodiment of the utility model provides a drip-proof liquid storage bottle for storing various liquids and taking out liquids for use according to needs.

[0035] Further, see Figure 2The liquid storage bottle of the utility model comprises a bottle body 100, which has a cavity and a bottle opening, and the liquid is stored in the bottle body 100. A bottle cap 200 is arranged at the bottle opening of the bottle body 100. After the bottle cap 200 is installed on the bottle body 100, the cavity in the bottle body 100 becomes a relatively sealed space. After opening the bottle cap 200, the liquid can be added to the bottle body 100.

[0036] Furthermore, a liquid outlet pipe 300 is provided on the bottle cap 200, and the lower end of the liquid outlet pipe 300 extends into the cavity of the bottle body 100, and the upper end of the liquid outlet pipe 300 is provided with a liquid outlet nozzle 310, and the liquid outlet nozzle 310 extends out of the bottle body 100. The liquid outlet pipe 300 is connected with the liquid outlet nozzle 310, and the liquid in the bottle body 100 can flow out from the liquid outlet nozzle 310 along the liquid outlet pipe 300.

[0037] Furthermore, a pressure pump 400 is provided on the bottle cap 200 , and the pressure pump 400 has an air outlet connected to the cavity of the bottle body 100 . The pressure pump 400 is used to apply pressure to the cavity of the bottle body 100 to press out the liquid in the bottle body 100 and flow out from the liquid outlet 310 .

[0038] Furthermore, the bottle cap 200 has a liquid gathering reflux area 220, which is located at the lower side of the liquid outlet nozzle 310 and is used to receive the liquid seeping out of the liquid outlet nozzle 310. The liquid gathering reflux area 220 has a reflux hole 221 connected to the cavity of the bottle body 100. When the bottle body 100 and the bottle cap 200 are in a flat state, the liquid gathering reflux area 220 guides the liquid to flow to the reflux hole 221, so that the liquid on the liquid gathering reflux area 220 flows back into the bottle body 100 through the reflux hole 221.

[0039] Furthermore, the bottle cap 200 is also provided with a one-way valve structure, which includes a first one-way valve 500 and a second one-way valve 600. Figure 3 The first one-way valve 500 is located between the liquid outlet pipe 300 and the liquid outlet nozzle 310. The first one-way valve 500 is used to limit the liquid from flowing from the liquid outlet pipe 300 to the liquid outlet nozzle 310, that is, to limit the liquid in the bottle body 100 to be output to the liquid outlet nozzle 310 in one direction, and cannot flow back along the liquid outlet pipe 300. Figure 4 The second one-way valve 600 is located on the reflux hole 221 , and is used to limit the liquid from flowing from the liquid gathering reflux area 220 into the bottle body 100 , that is, only the liquid in the liquid gathering reflux area 220 is allowed to flow back into the bottle body 100 , while the liquid in the bottle body 100 cannot flow out from the reflux hole 221 .

[0040] In actual work, refer to Figure 5When liquid needs to be discharged, the liquid storage bottle of the utility model is in the pouring state, and the pressure pump 400 applies pressure to the cavity of the bottle body 100 to press the liquid out of the bottle body 100, and the liquid flows out after passing through the liquid outlet pipe 300, the first one-way valve 500, and the liquid outlet nozzle 310 in sequence, thereby achieving liquid extraction. However, due to the function of the second one-way valve 600, the liquid in the bottle body 100 cannot flow out of the reflux hole 221 through the position of the second one-way valve 600.

[0041] Reference Figure 6 When the liquid storage bottle of the utility model is no longer required to output the liquid, the pressure pump 400 is notified to work in a horizontal state, and the first one-way valve 500 can isolate the air from the liquid in the bottle to prevent the liquid from deteriorating. The second one-way valve 600, in addition to allowing the liquid in the liquid collection reflux area 220 to flow back into the bottle body 100, can also prevent the liquid from being ejected from the reflux hole 221 due to gas expansion when the air changes from cold to hot or the liquid temperature is high.

[0042] In some embodiments, the one-way valve structure is a rubber pad one-way valve structure, and the rubber pad one-way valve structure has a one-way movable film for limiting the one-way flow of the liquid, that is, the flow direction of the liquid is limited by the characteristic that the one-way movable film can only move in one direction. When the liquid flows to the sealable port, the liquid will drive the ball to block the sealable port, and the liquid cannot flow out of the sealable port. When the liquid flows through the rubber pad one-way valve structure in a predetermined direction, the liquid will push away the one-way movable film. On the contrary, when the liquid flows through the rubber pad one-way valve structure in the opposite direction, the one-way movable film cannot move and blocks the liquid, which is equivalent to the liquid can only flow out in one direction.

[0043] In this embodiment, optionally, the rubber pad type one-way valve structure limits the unidirectional movement of the one-way movable film by means of an internal limiting rib, that is, when the one-way movable film moves in a predetermined direction, the limiting rib does not limit the movement of the one-way movable film. Conversely, when the one-way movable film moves in the opposite direction, the limiting rib presses against the one-way movable film.

[0044] In this embodiment, optionally, the one-way movable film can realize limited reverse movement through its own structure, and the details can be referred to the similar structure in the prior art, which will not be described in detail here.

[0045] Some embodiments, see Figure 3 , Figure 4The one-way valve structure is a ball-type one-way valve structure, which controls the liquid to flow in only one specific direction. The one-way valve structure includes a valve body, and the valve body has a valve channel. A ball is arranged in the valve channel, and the liquid can flow in the valve channel in the valve body and pass through the ball position. The two ends of the valve channel are a sealable port and a one-way normal port, respectively, and the one-way normal port has a normal groove. When the liquid flows to the sealable port, the liquid will drive the ball, so that the ball blocks the sealable port, and the liquid cannot flow out of the sealable port. When the liquid flows to the one-way normal port, the liquid will drive the ball to the position of the one-way normal port, but due to the normal groove of the one-way normal port, the liquid can flow out through the normal groove, which is equivalent to the liquid can flow out of the one-way normal port in one direction.

[0046] Some embodiments, see Figure 3 The first one-way valve 500 ensures the flow of liquid in a specific direction and prevents backflow, wherein a first one-way valve ball 510 is disposed in the first one-way valve 500, which is used as a valve to control the opening and closing of the first one-way valve 500. The lower end of the first one-way valve 500 is provided with a first one-way valve input port 520 as a sealable port connected to the liquid outlet pipe 300, and the upper end of the first one-way valve 500 is provided with a first one-way valve output port 530 as a one-way normally open port connected to the liquid outlet nozzle 310, and the first one-way valve output port 530 is provided with a first output port groove 531 as a normally open groove. When the pressure pump 400 is started, when the liquid flows out from the liquid outlet pipe 300 to the liquid outlet nozzle 310, the liquid drives the first one-way valve ball 510 to the first one-way valve output port 530, and the liquid can flow out to the liquid outlet nozzle 310 through the first output port groove 531, which is equivalent to the liquid power pushing the first one-way valve ball 510 to move to the first one-way valve output port 530, but ensuring that the liquid passes through the first output port groove 531 smoothly and flows smoothly to the liquid outlet nozzle 310 to meet the liquid collection work requirements. When the pressure pump 400 stops working, due to the loss of power, the first one-way valve ball 510 falls and blocks the first one-way valve input port 520, and the liquid cannot flow into the liquid outlet pipe 300 through the first one-way valve input port 520. This design can prevent the possibility of liquid flowing back from the liquid outlet nozzle 310 to the liquid outlet pipe 300, thereby ensuring the one-way flow characteristics of the system.

[0047] This structure has the advantages of simplicity and easy maintenance. Its ball-type design makes the opening and closing of the valve faster and more flexible, and also facilitates daily cleaning and maintenance work, and also ensures the one-way flow of liquid, prevents backflow, and improves the stability and reliability of the system.

[0048] In this embodiment, optionally, the first output port groove 531 is located at a lower side of the first one-way valve output port 530 .

[0049] Some embodiments, see Figure 4The second one-way valve 600 ensures the flow of liquid in a specific direction and prevents backflow, wherein a second one-way valve ball 610 is arranged inside the second one-way valve 600, which is used as a valve to control the opening and closing of the second one-way valve 600. The upper end of the second one-way valve 600 is provided with a second one-way valve input port 620 as a sealable port connected to the liquid collection reflux area 220, and the lower end of the second one-way valve 600 is provided with a second one-way valve output port 630 as a one-way normal opening connected to the cavity of the bottle body 100, and the second one-way valve output port 630 is provided with a second output port groove 631 as a normal opening. When the pressure pump 400 is started, when the liquid flows out to the liquid outlet nozzle 310, the air pressure drives the second one-way valve ball 610 to press upward against the second one-way valve input port 620, and the liquid will not flow out of the reflux hole 221 through the second one-way valve 600, thereby ensuring the unidirectionality of the liquid flow. The gas can slowly flow out and release pressure through the gap between the second one-way valve ball 610 and the second one-way valve input port 620. This design not only ensures the one-way flow of the liquid, but also allows the gas to escape when needed, thereby maintaining the stability of the system. When the pressure pump 400 stops working, the second one-way valve ball 610 falls on the second one-way valve output port 630, and no longer continues to support the second one-way valve input port 620. The liquid in the liquid collection reflux area 220 can enter the second one-way valve 600 through the second one-way valve input port 620, and flow into the bottle body 100 from the second output port groove 631, realizing the reflux and reuse of the liquid.

[0050] This structure has the advantages of simplicity and easy maintenance. The above design cleverly combines the one-way valve and the ball mechanism to achieve effective separation and control of liquid and gas. It can not only prevent liquid backflow and improve the efficiency of the system, but also allow gas to escape when necessary to maintain the stability of the system. At the same time, by utilizing the effect of gravity, the ball falls naturally when no external force is required, simplifying the operation and maintenance process.

[0051] In this embodiment, optionally, the second output port groove 631 is located at a side of the second one-way valve output port 630 .

[0052] Some embodiments, see Figure 2 The liquid outlet nozzle 310 and the liquid outlet pipe 300 form an "L"-shaped structure, with the liquid outlet nozzle 310 as a vertical part and the liquid outlet pipe 300 extending forward as a horizontal part, so that the liquid outlet nozzle 310 can extend to spray liquid.

[0053] Some embodiments, see Figure 1 , Figure 2The bottle cap 200 is provided with a liquid outlet protection cover 210, and the liquid outlet protection cover 210 has a cover body cavity. The liquid outlet protection cover 210 covers the liquid outlet 310 when the cover is closed. When it is not necessary to pour or take liquid, the liquid outlet protection cover 210 can be covered to cover the liquid outlet 310 and the liquid collection reflux area 220.

[0054] In this embodiment, the liquid spout protection cover 210 optionally includes a cover shaft, and the liquid spout protection cover 210 is connected to the bottle cap 200 via the cover shaft. In this way, the liquid spout protection cover 210 can be used as a flip-top structure and can rotate along the cover shaft, which is convenient to use.

[0055] In this embodiment, optionally, a detachable connection structure is provided between the liquid spout protection cover 210 and the bottle cap 200, so as to facilitate the disassembly and cleaning of the liquid spout protection cover 210 .

[0056] In this embodiment, optionally, when the liquid outlet nozzle protection cover 210 is in the closed state, the edge of the liquid outlet nozzle protection cover 210 is sealed and connected to the edge of the liquid collection reflux area 220 .

[0057] In some embodiments, the liquid gathering reflux area 220 has a reflux slope, so that the liquid on the liquid gathering reflux area 220 can naturally flow into the reflux hole 221 along the reflux slope.

[0058] In some embodiments, an operation panel 240 is provided on the bottle cap 200 to facilitate operation by a user, especially to control the operation of the pressure pump 400 .

[0059] In some embodiments, a bottle cap connecting ring 260 is disposed on the lower side of the bottle cap 200 , and the bottle cap 200 is connected to the bottle opening position of the bottle body 100 via the bottle cap connecting ring 260 .

[0060] In this embodiment, optionally, the bottle opening position of the bottle body 100 and the bottle cap connecting ring 260 of the bottle cap 200 may be connected via threads.

[0061] In some embodiments, a bottle cap boss 270 is provided on the bottle cap 200 to improve the structural strength of the bottle cap 200 and can also serve as an installation location for the pressure pump 400 .

[0062] In some embodiments, a handle 230 is provided on the bottle cap 200, so that the user can hold the handle 230 to lift the liquid storage bottle of the utility model.

[0063] In some embodiments, the bottle cap 200 is provided with a battery 250, and the battery 250 is electrically connected to the pressure pump 400 to supply power to the pressure pump 400 and other electrical components of the liquid storage bottle of the utility model. In this way, the liquid storage bottle of the utility model can be started without wiring.
