[0002] Spray is artificial fog. Simply put, a high-pressure system sprays liquid in the form of extremely fine water particles. These tiny artificial fog particles can drift and suspend in the air for a long time, thus forming a white mist spectacle that is very similar to the effect of natural fog, so it is called spray. Spray is a mixture of tiny particles suspended in a gas (such as air). These particles may be tiny drops of water or pigment.

[0029] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0030] See also Figure 1 , Figure 2The spray pump tube provided in this embodiment includes a suction pipe 100 and a blocking piece 200. The middle position of the suction pipe 100 is a connecting section 110, and a connecting portion is provided on the pipe body of the connecting section 110, and the connecting portion is used to connect the suction end of the spray pump 300. There are two blocking pieces 200, and the two blocking pieces 200 are arranged in the suction pipe 100 and are respectively arranged on both sides of the connecting section 110, and the blocking piece 200 can move in the suction pipe 100. Among them, both ends of the suction pipe 100 and both ends of the connecting section 110 are provided with a limiting portion 120, and the blocking piece 200 is adapted to the limiting portion 120 and can block the pipe opening at the limiting portion 120.

[0031] The two ends of the suction pipe 100 in this embodiment are respectively a first suction section 130 and a second suction section 140. The first suction section 130 and the second suction section 140 are respectively arranged on both sides of the connecting section 110 and are connected to the connecting section 110. The end of the first suction section 130 is a first suction port, and the end of the second suction section 140 is a second suction port, and the first suction port and the second suction port are arranged at intervals in the vertical direction.

[0032] Specifically, the spray pump pipe in this embodiment is used to connect with the spray pump 300. After the connection portion in the suction pipe 100 is connected with the suction end of the spray pump 300, the suction pipe 100 is arranged in the vertical direction, with one end of the suction pipe 100 located at the top and the other end located at the bottom.

[0033] When the spray pump 300 pumps liquid, negative pressure is generated at the suction end of the spray pump 300, and suction is performed at both ends of the suction pipe 100. At this time, the blocking member 200 located at the top of the suction pipe 100 moves downward under the action of gravity and suction to cooperate with the limiting portion 120 above the connecting portion, thereby blocking the top of the suction pipe 100, and the liquid is sucked into the spray pump 300 from the bottom of the suction pipe 100.

[0034] Similarly, when the spray pump 300 and the spray pump tube are used inverted, the liquid flows to connect with the spray pump 300, and the upper limiting portion 120 of the suction tube 100 cooperates with the blocking member 200 to achieve blocking of the upper pipe opening of the suction tube 100, and the liquid is sucked into the lower pipe opening of the suction tube 100, thereby achieving the forward spraying and reverse spraying of the spray pump 300. In this way, the residual amount of liquid in the container after the forward spraying and reverse spraying is small, and the discharge amount is stable.

[0035] In this embodiment, the limiting portions 120 of the first suction section 130 and the second suction section 140 away from the connecting section 110 are both tapered from inside to outside. The limiting portions 120 of the first suction section 130 and the second suction section 140 close to the connecting section 110 are both widened from inside to outside.

[0036] In this embodiment, the limiting part 120 is a conical groove body, the first suction port and the second suction port are both located at the tip of the conical groove body, and the tip of the conical groove body at the limiting part 120 of the first suction section 130 and the second suction section 140 near the connecting section 110 is connected to the connecting section 110. When the spray pump 300 is placed upright or inverted for spraying, the blocking member 200 located at the upper part of the spray pump pipe moves toward the connecting section 110 under the action of the suction force and gravity of the spray pump 300, and blocks the pipe opening located at the top of the connecting section 110, so that the pipe opening above the connecting section 110 is closed, and the liquid cannot be sucked into the connecting section 110 and the spray pump 300 from the pipe opening above the connecting section 110. Correspondingly, at this time, the blocking piece 200 located at the lower part of the spray pump tube moves downward under the action of gravity, and under the suction of the spray pump 300, the blocking piece 200 moves upward but cannot block the bottom pipe opening of the connecting section 110. The liquid flows into the spray pump tube from the bottom pipe opening of the spray pump tube and enters the spray pump 300 from the connecting part, realizing upright or inverted spraying.

[0037] In this embodiment, the blocking member 200 is a blocking ball, the diameter of which is larger than the minimum diameter of the limiting portion 120 and smaller than the inner wall diameter of the suction pipe 100 .

[0038] Specifically, the blocking cylinder in this embodiment is a steel ball, and the diameter of the steel ball is larger than the minimum diameter of the stopper 120, which can ensure that the stopper 120 can be completely closed when blocking. In addition, the diameter of the steel ball is smaller than the inner wall diameter of the suction pipe 100, which can ensure that the steel ball can move in the spray pipe, so that the steel ball can move in the spray pipe under the action of gravity or suction force.

[0039] In this embodiment, a mounting port for connecting a long tube is provided on the second suction port.

[0040] Among them, after the spray pump tube in this embodiment is connected to the spray pump 300, the first suction port of the spray pump tube is located at the top, and the second suction port of the spray pump tube is located at the bottom. Since the suction end of the spray pump 300 in this embodiment is located at the top, after the spray pump tube is installed, the position of the first suction port is very close to the bottom surface of the spray pump 300, and the first suction port can suck deeper liquid during reverse spraying without being lengthened. After the installation port at the second suction port is connected to the long tube, the length of the spray pump tube can be extended, and the bottom suction position of the spray pump tube can be changed. The spray pump 300 can perform suction through the bottom pipe port of the long tube, avoiding the second suction port from being unable to suck deeper liquid, resulting in a large amount of residual liquid in the liquid container.

[0041] And, correspondingly, when the suction end of the spray pump 300 is at a greater distance from the bottom surface of the spray pump 300, a mounting port can also be provided at the first suction port to mount a long tube, thereby changing the upper suction position of the spray liquid pipe.

[0042] In this embodiment, the spray pump tube further includes an extension tube 150. The extension tube 150 is connected to the installation port.

[0043] The extension tube 150 is the long tube mentioned above. The extension tube 150 in this embodiment is a plastic tube body with relatively stable chemical properties.

[0044] In this embodiment, the connecting portion is a curved pipe structure, one end of which is connected to the connecting section 110 , and the other end of which is used to connect to the spray pump 300 .

[0045] Specifically, the connecting portion in this embodiment is a right-angle elbow. The right-angle elbow includes a first pipe section extending in the vertical direction and a second pipe section extending in the horizontal direction. The top end of the first pipe section is connected to and communicated with the suction end of the spray pump 300, the bottom end of the first pipe section is connected to one end of the second pipe section, and the other end of the second pipe section is connected to the connecting portion of the spray pump pipe and communicated with the connecting section 110. Under the structure of the right-angle elbow, after the spray pump pipe is connected to the suction end of the spray pump 300, it can ensure that the first suction port and the second suction port are respectively located on the upper and lower sides of the connecting section 110, so as to realize the forward spraying and reverse spraying actions of the spray pump 300 or the sprayer.

[0046] In this embodiment, the bent pipe structure and the connecting section 110 are an integrated structure. A through hole is provided at the bend of the bent pipe structure, and a sealing plug is inserted into the through hole.

[0047] In order to ensure the structural strength and sealing of the bent pipe structure, the bent pipe structure in this embodiment is made by integrated injection molding. Due to the limitation of the injection molding process, an air hole needs to be left at the connection between the first pipe section and the second pipe section. In this embodiment, the sealing plug is used to block the air hole to ensure the sealing of the bent pipe structure.

[0048] The spray pump 300 provided in this embodiment includes a pump body and a spray pump pipe provided. The pump body includes a liquid inlet pipe, and the liquid inlet pipe is connected to the connecting portion of the spray pump pipe.

[0049] Specifically, the pump body in this embodiment is a conventional spray pump 300 that is common in the prior art, including a gland 310, a connecting rod 320, a needle valve 330, a piston, and a steel ball 340 in the pump. When in use, the gland 310 is pressed by hand to move the connecting rod 320 up and down, driving the needle valve 330, the piston, and the steel ball 340 in the pump, so that negative pressure is generated in the pump body cavity. The liquid is sucked from the spray pump tube by the suction force generated by the pressure difference between the inside and outside of the pump body cavity, and passes through the side of the steel ball 340 in the pump.

[0050] The liquid inlet pipe of the spray pump 300 in this embodiment is used to connect to the spray pump pipe and suck liquid. Specifically, the pipe opening of the liquid inlet pipe is the suction end of the pump body.

[0051] The sprayer provided in this embodiment includes a bottle body and a spray pump tube provided. The bottle body has a liquid storage space connected to the spray pump 300, the spray pump tube of the spray pump 300 is located in the liquid storage space, and one end of the suction pipe 100 of the spray pump tube is located at the bottom of the liquid storage space, and the other end is located at the top of the liquid storage space.

[0052] Specifically, the mouth of the bottle in this embodiment is located at the top of the bottle, the spray pump 300 is arranged at the mouth of the bottle, a thread is arranged on the mouth of the bottle, the spray pump 300 is connected to the bottle by threaded matching, the liquid inlet pipe of the spray pump 300 is in the bottle, and the suction end of the liquid inlet pipe is located at an upper position in the bottle. The spray pump pipe is connected to the spray pump 300, the first suction port of the spray pump pipe is located at the upper part of the bottle near the mouth of the bottle, the second suction port of the spray pump pipe is connected to the extension pipe 150, and the bottom end of the extension pipe 150 is located at the bottom of the bottle.

[0053] When the sprayer is placed upright for use, the lower pipe opening of the connecting section 110 of the spray pump tube is closed by the steel ball above, so that the first suction port is closed and the liquid cannot enter the connecting section 110 from the first suction port. At the same time, the steel ball below the connecting section 110 moves upward under the action of suction, and the liquid can enter the spray pump 300 through the extension tube 150 and the second suction port.

[0054] Accordingly, when the sprayer is inverted for use, the upper pipe opening of the connecting section 110 of the spray pump tube is closed by the upper steel ball, so that the second suction port is closed, and the liquid cannot enter the connecting section 110 from the second suction port or the extension tube 150. At the same time, the steel ball below the connecting section 110 moves upward under the action of suction, and the liquid can enter the spray pump 300 through the first suction port, thereby realizing the inverted use of the sprayer.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
