Description

Technical Field

[0001] This utility model relates to the field of spray head technology, specifically a spray component for a spray device. Background Technology

[0002] A spray nozzle is a device that converts liquid inside a bottle into a mist by manually pressing it. It uses a fine nozzle design to break down the liquid into uniform and fine mist particles, achieving a wider coverage area and more efficient liquid utilization, and is widely used in daily life.

[0003] Existing patent application number: 202322806905.5 A press-type spray nozzle includes a main body, the main body including a shell, a pressing mechanism installed on the inner wall of the shell, the pressing mechanism including a connecting plate, the surface of the connecting plate being in contact with the inner wall of the shell, a third through hole being formed on the inner wall of the connecting plate, a second groove being formed on the inner wall of the third through hole, a partition being fixedly connected inside the second groove, a fourth through hole being formed on the surface of the partition, a second through hole being formed on the surface of the shell, and the second through hole being located in front of the third through hole, a water outlet pipe being fixedly connected to the inner wall of the second through hole.

[0004] The aforementioned patent describes a spray head assembly. In actual use, the spray head pumps liquid through a straw to atomize and spray it out. The straw has a single function, and when the spray head is held at an angle or upside down, the end of the straw is prone to leaving the liquid surface, causing the spray head to be unable to pump liquid normally. It can only be operated at the normal holding angle, which is very inconvenient. Therefore, we propose a spray assembly specifically for spray devices to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a spray assembly specifically for a spraying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a spray assembly for a spraying device, comprising a press pump, a nozzle, and a multi-angle suction structure. The press pump has a nozzle on its front side and a multi-angle suction structure connected to its bottom interface. The multi-angle suction structure includes an upper suction tube, a lower suction tube, a counterweight ball, and a suction port. The bottom interface of the press pump is connected to the upper suction tube, and the bottom end of the upper suction tube is connected to the lower suction tube. A counterweight ball is fitted onto the bottom end of the lower suction tube, and a suction port is formed on the surface of the counterweight ball, which connects to the interior of the lower suction tube.

[0007] Preferably, the upper straw is a rigid tube and the lower straw is a flexible tube.

[0008] Preferably, the inner diameter of the upper straw and the lower straw are the same.

[0009] Preferably, there are no fewer than two suction ports, and the suction ports are arranged in a ring at equal intervals in the middle of the surface of the counterweight ball.

[0010] Preferably, the straw is composed of an inner PVC layer, an outer PVC layer, and a flexural layer. The inner PVC layer is the inner structure of the straw, the outer PVC layer is the outer structure of the straw, and the flexural layer is embedded between the inner PVC layer and the outer PVC layer.

[0011] Preferably, the flexural layer is made entirely of TPE material.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention features a multi-angle suction structure at the bottom interface of the pump. When the pump is held at an angle or upside down, the lower suction tube bends and moves under the weight of the counterweight ball, ensuring that the counterweight ball is always below the liquid surface. This ensures that the pump can pump liquid normally at various holding angles, making it more convenient to use.

[0013] This invention incorporates a flexural layer between the inner and outer PVC layers. This flexural layer has good elasticity and can quickly recover its shape, effectively enhancing the flexural resistance of the lower straw and preventing it from buckling when bent, which could lead to poor liquid pumping.

[0015] In the diagram: Press pump-1, Nozzle-2, Multi-angle suction structure-3, Upper suction tube-31, Lower suction tube-32, Inner PVC layer-321, Outer PVC layer-322, Flexural layer-323, Counterweight ball-33, Suction port-34. Detailed Implementation

[0016] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0017] Please see Figure 1This utility model provides a spray assembly for a spraying device, including a press pump 1, a nozzle 2 and a multi-angle liquid suction structure 3. The press pump 1 has a nozzle 2 on the front of the pump head and the multi-angle liquid suction structure 3 is connected to the bottom interface of the press pump 1.

[0018] Specifically, during use, the press pump 1 is repeatedly pressed to generate negative pressure suction, allowing the counterweight ball 33 to draw liquid through the liquid suction port 34. Subsequently, the liquid is pumped into the press pump 1 through the lower suction pipe 32 and the upper suction pipe 31, and finally atomized and sprayed out from the nozzle 2, thereby realizing the spraying action.

[0019] Please see Figure 2-3 This utility model provides a spray component for a spraying device. The multi-angle liquid suction structure 3 includes an upper suction pipe 31, a lower suction pipe 32, a counterweight ball 33, and a liquid suction port 34. The bottom interface of the press pump 1 is connected to the upper suction pipe 31. The bottom end of the upper suction pipe 31 is connected to the lower suction pipe 32. The counterweight ball 33 is sleeved on the bottom end of the lower suction pipe 32. The surface of the counterweight ball 33 has a liquid suction port 34, which is connected to the inside of the lower suction pipe 32.

[0020] In this invention, the upper suction tube 31 is a rigid tube and the lower suction tube 32 is a flexible tube, which avoids the flexible tube from becoming too long and getting tangled during use. In addition, the inner diameter of the upper suction tube 31 and the lower suction tube 32 are the same, ensuring a smooth and stable liquid aspiration process.

[0021] The number of suction ports 34 is not less than two, and the suction ports 34 are equidistantly arranged in a ring around the center of the surface of the counterweight ball 33 to prevent the suction ports 34 from being blocked when the counterweight ball 33 is against the inner wall of the container, which would cause the liquid pump to be unsmooth.

[0022] Please see Figure 4 This utility model provides a spray assembly for a spraying device. The lower suction pipe 32 is composed of an inner PVC layer 321, an outer PVC layer 322 and a flexural layer 323. The inner PVC layer 321 is the inner structure of the lower suction pipe 32, the outer PVC layer 322 is the outer structure of the lower suction pipe 32, and the flexural layer 323 is embedded between the inner PVC layer 321 and the outer PVC layer 322.

[0023] To further explain, the entire anti-bending layer 323 is made of TPE material. TPE has good elasticity and can quickly recover its shape, which can effectively enhance the anti-bending performance of the lower straw 32 and prevent the lower straw 32 from buckling when bent, thus causing the liquid pumping to be unsmooth.

[0024] Specifically, when the pump 1 is held at an angle or upside down, the lower suction tube 32 bends and moves under the weight of the counterweight ball 33, ensuring that the counterweight ball 33 is always below the liquid surface. This ensures that the pump 1 can pump liquid normally at various holding angles, making it more convenient to use. In particular, by setting an anti-bending layer 323 between the inner PVC layer 321 and the outer PVC layer 322, the anti-bending layer 323 has good elasticity and can quickly restore its shape, which can effectively enhance the anti-bending performance of the lower suction tube 32 and prevent the lower suction tube 32 from breaking when bent, which would cause the liquid pumping to be unsmooth.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
