Description

Technical Field

[0001] This utility model relates to the field of spray device technology, and more specifically, to a spray device for reducing liquid residue. Background Technology

[0002] A spray device is a device that uses a specific structure to convert liquid into fine droplets and spray them evenly. It is widely used in cosmetics, pharmaceuticals, agriculture, industrial cleaning, home care and many other fields. Its core function is to achieve efficient dispersion and precise delivery of liquid through pressure control, flow channel design and atomization technology.

[0003] However, existing technologies have some problems: some liquid always remains at the bottom of the spray bottle in existing spraying devices and cannot be sprayed out, resulting in liquid residue inside the bottle and waste of resources. Therefore, we propose a spraying device to reduce liquid residue. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a spray device that reduces liquid residue.

[0005] According to a first aspect of the present invention, a spray device for reducing liquid residue is provided, comprising a bottle body, a base fixedly connected to one end of the bottle body, the base being hollow inside and having an annular groove formed thereon, an injection head fixedly connected to the bottle body, a press-type nozzle detachably connected to the injection head, a liquid suction component being provided on the press-type nozzle, an air inlet being provided on one side of the bottle body, an air inlet pipe fixedly connected to the inner wall of the air inlet, and an air inlet component being provided inside the air inlet pipe.

[0006] Optionally, the injection head is provided with threads, the press nozzle is threadedly connected to the injection head, and the press nozzle is provided with an upper cover.

[0007] Optionally, the liquid suction assembly includes a liquid suction tube, one end of which is fixedly connected to the press nozzle, and the other end of which is fixedly connected to a spiral hose.

[0008] Optionally, a straw head is fixedly connected to one end of the spiral hose, a counterweight is fixedly connected to the straw head, a water inlet is provided on the counterweight, and the counterweight is movably connected in an annular groove.

[0009] Optionally, the intake assembly includes a valve seat, a valve is provided on the intake pipe, the valve seat is movably connected inside the valve, and a sealing ring is fixedly connected to the valve seat.

[0010] Optionally, a fixing ring is fixedly connected to the valve seat, the fixing ring is slidably connected inside the air intake pipe, and a spring is fixedly connected to the fixing ring, the spring being fixedly connected to the inner wall of the air intake pipe.

[0011] According to one embodiment of this disclosure, a base is fixedly connected to one end of the bottle body. The base is hollow inside. The hollow design can reduce production costs and reduce the weight of the device, making it easy to carry and use. An annular groove is provided on the base, and a smooth curved surface is formed by a convex part in the middle of the base, so that liquid can flow from the convex part to the annular groove, and then flow through the liquid suction component to the press nozzle for spraying, thereby avoiding liquid residue at the bottom of the bottle and causing resource waste.

[0012] This utility model is equipped with an air intake component. During the press spraying process, in order to avoid the liquid being difficult to spray out due to the low air pressure inside the bottle, resulting in liquid residue inside the bottle, when the pressure inside the bottle is too low, the external air pressure will push the valve seat, causing the valve seat to move and compress the spring of the fixing ring, so that the valve seat will no longer block the air intake pipe, thereby avoiding affecting the spraying of liquid inside the bottle and reducing liquid residue inside the bottle.

[0013] The bottle body of this utility model is made of elastic material. When there is little liquid left in the bottle, the internal space of the bottle can be reduced by pressing the bottle body, thereby increasing the internal pressure of the bottle and making it easier for the liquid to be sprayed out from the press nozzle. After releasing the bottle body, air can be injected back into the bottle body through the air intake component, so that the bottle body can be pressed repeatedly to spray out the liquid in the bottle, reducing the liquid residue in the bottle.

[0022] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0024] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0025] like Figure 1-4 As shown, a spray device for reducing liquid residue includes a bottle body 1 made of elastic material. The main function of the bottle body 1 is to store liquid and prevent leakage and evaporation.

[0026] Furthermore, a base 2 is fixedly connected to one end of the bottle body 1. The base 2 is hollow inside. The hollow design can reduce production costs and reduce the weight of the device, making it easy to carry and use. An annular groove 3 is provided on the base 2. The middle part of the base 2 is raised to form a smooth curved surface, so that the liquid can flow from the raised part to the annular groove 3, and then flow through the liquid suction component 6 to the press nozzle 5 for spraying, thereby avoiding liquid residue at the bottom of the bottle and causing resource waste.

[0027] Furthermore, a liquid injection head 4 is fixedly connected to the bottle body 1. The liquid injection head 4 is used to add liquid into the bottle body 1. A press nozzle 5 is detachably connected to the liquid injection head 4. The liquid injection head 4 is provided with threads. The press nozzle 5 is threadedly connected to the liquid injection head 4. A top cover 9 is provided on the press nozzle 5.

[0028] Specifically, the press nozzle 5, connected by threads, facilitates the opening of the injection head 4 to inject liquid into the bottle body 1. The top cover 9 is used to prevent the press nozzle 5 from being contaminated or accidentally pressed. The principle of the press nozzle 5 is based on mechanical pressure transmission and fluid dynamics. By pressing, the liquid in the bottle is converted into a uniform mist and sprayed out. The press nozzle 5 is a mature existing technology, which is believed to be well understood by those skilled in the art, so it will not be described in detail here.

[0029] Furthermore, the press nozzle 5 is provided with a liquid suction component 6, which includes a liquid suction tube 61. One end of the liquid suction tube 61 is fixedly connected to the press nozzle 5, and the other end of the liquid suction tube 61 is fixedly connected to a spiral hose 62.

[0030] Furthermore, a suction head 63 is fixedly connected to one end of the spiral hose 62, and a counterweight 64 is fixedly connected to the suction head 63. A water inlet hole is provided on the counterweight 64, and the counterweight 64 is movably connected in the annular groove 3.

[0031] Specifically, the counterweight 64 uses gravity to keep the straw head 63 always vertically downward, ensuring that it contacts the liquid surface or the bottom of the bottle. At the same time, when the bottle body 1 is tilted, the counterweight 64 can automatically slide to the lowest point of the liquid inside the bottle body 1, so that the device can still be in close contact with the bottom of the bottle even when tilted, thereby reducing the amount of liquid residue inside the bottle.

[0032] Furthermore, a spiral hose 62 is provided between the suction tube 61 and the straw head 63. The retractable spiral structure compensates for the range of motion of the straw head 63, ensuring that the connection between the suction tube 61 and the straw head 63 is not insufficient due to bottle tilting, or that the tube is twisted, preventing the liquid from being sprayed out from the press nozzle 5.

[0033] Furthermore, an air inlet is provided on one side of the bottle body 1, and an air inlet pipe 7 is fixedly connected to the inner wall of the air inlet. An air inlet assembly 8 is provided inside the air inlet pipe 7. The air inlet assembly 8 includes a valve seat 81. A valve is provided on the air inlet pipe 7. The valve seat 81 is movably connected inside the valve. A sealing ring 82 is fixedly connected to the valve seat 81.

[0034] Furthermore, a retaining ring 83 is fixedly connected to the valve seat 81, the retaining ring 83 is slidably connected inside the air intake pipe 7, and a spring 84 is fixedly connected to the retaining ring 83, the spring 84 is fixedly connected to the inner wall of the air intake pipe 7.

[0035] Specifically, during the press spraying process, in order to avoid the liquid being difficult to spray out due to the low air pressure inside the bottle, resulting in liquid residue inside the bottle, when the pressure inside the bottle is too low, the external air pressure will push the valve seat 81, causing the valve seat 81 to drive the fixed ring 83 to compress the spring 84 and move, so that the valve seat 81 no longer blocks the air inlet pipe 7, thereby avoiding affecting the spraying of liquid inside the bottle and reducing liquid residue inside the bottle.

[0036] Furthermore, the bottle body 1 of this device is made of elastic material. When there is little liquid remaining in the bottle, the internal space of the bottle body 1 can be reduced by pressing the bottle body 1, thereby increasing the pressure inside the bottle. This makes it easier for the liquid to be sprayed out from the press nozzle 5. After releasing the bottle body 1, air can be injected back into the bottle body 1 through the air intake component 8, so that the bottle body 1 can be pressed repeatedly to spray out the liquid inside the bottle, reducing the liquid residue inside the bottle.

[0037] The aforementioned spray device for reducing liquid residue has a base 2 fixedly connected to one end of the bottle body 1. The base 2 is hollow inside, and the hollow design can reduce production costs and reduce the weight of the device, making it easy to carry and use. An annular groove 3 is provided on the base 2, and the middle part of the base 2 is raised to form a smooth curved surface, so that the liquid can flow from the raised part to the annular groove 3, and then flow through the liquid suction component 6 to the press nozzle 5 for spraying, thereby avoiding liquid residue at the bottom of the bottle and causing resource waste.

[0038] This utility model is equipped with an air intake component 8. During the press spraying process, in order to avoid the liquid being difficult to spray out due to the low air pressure inside the bottle, resulting in liquid residue inside the bottle, when the pressure inside the bottle is too low, the external air pressure will push the valve seat 81, causing the valve seat 81 to drive the fixed ring 83 to compress the spring 84 and move, so that the valve seat 81 no longer blocks the air intake pipe 7, thereby avoiding affecting the spraying of liquid inside the bottle and reducing liquid residue inside the bottle.

[0039] The bottle body 1 of this utility model is made of elastic material. When there is little liquid left in the bottle, the internal space of the bottle body 1 can be reduced by pressing the bottle body 1, thereby increasing the pressure inside the bottle and making it easier for the liquid to be sprayed out from the press nozzle 5. After releasing the bottle body 1, air can be injected back into the bottle body 1 through the air intake component 8, so that the bottle body 1 can be pressed repeatedly to spray out the liquid inside the bottle, reducing the liquid residue inside the bottle.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
