However, the gas in the foam agent bottle will slowly leak out through the bottle mouth, causing the air pressure in the foam agent bottle to decrease, making it difficult to spray the foam agent in the used foam agent bottle that has been stored for a long time, affecting the secondary use of the foam agent bottle. Utility Model Content

[0004] The purpose of the utility model is to provide a foam agent pressurized injection device, which can reduce the leakage speed of gas in the foam agent bottle, prolong the storage time of the foam agent, and increase the air pressure in the foam agent bottle to ensure the injection effect.

This device can reduce the leakage rate of gas in the foam agent bottle, extend the storage time of the foam agent, and increase the air pressure in the foam agent bottle to ensure injection effectiveness.

[0006] According to the foam agent pressurized injection device, a plurality of support sleeves are fixedly connected to the lower end of the bottle body at equal intervals and communicate with the bottle body. A first spring is fixedly connected to the bottom of the support sleeve, and the upper end of the first spring is fixedly connected to the lower end of the compression plate, thereby pushing the compression plate upward and reducing the force applied to the rotating screw.

[0007] According to the foam agent pressurized injection device, a connecting belt is fixedly connected to the middle of the outer end of the bottle body, and the end of the connecting belt away from the bottle body is fixedly connected to the upper end of the sealing cap, so as to connect the sealing cap and prevent the sealing cap from being lost.

[0008] According to the foam agent pressurized injection device, the pressure detection mechanism comprises a transparent tube, an indicator plate, a limiting ring, and a second spring. The transparent tube extends downward into the bottle body, and the lower end of the transparent tube is provided with an opening that communicates with the bottle body. The limiting ring is fixedly connected to the interior of the transparent tube and is located above the bottle body. The second spring is fixedly connected to the top of the transparent tube. The indicator plate is located in the transparent tube and is slidably connected to the inner wall of the transparent tube. The indicator plate is located between the limiting ring and the second spring, and the upper end of the indicator plate is fixedly connected to the lower end of the second spring. The pressure detection mechanism is used to detect whether the air pressure in the foam agent bottle meets the requirements for normal foam agent injection.

[0009] According to the foam agent pressurized injection device, a plurality of anti-slip bumps are equidistantly provided on the outer end of the sealing cover, and the anti-slip bumps are semi-cylindrical in structure, so as to increase the friction force on the surface of the sealing cover.

[0010] According to the foam agent pressurized injection device, the top end of the sealing cover is fixedly connected to a rubber sleeve, and the upper end of the injection head extends to the middle of the rubber sleeve and is slidably connected to the rubber sleeve, so as to further seal the foam agent bottle.

[0011] According to the foam agent pressurized injection device, an indicator mark is provided on the outer end of the transparent tube, so that a worker can directly observe the pressure in the foam agent bottle.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The screw pushes the compression plate to compress the space where the material in the foaming agent bottle is located, thereby increasing the air pressure in the foaming agent bottle and delaying the leakage rate of the gas in the foaming agent bottle through the sealing cover, ensuring the injection effect of the foaming agent when the foaming agent bottle is used and placed for a long time before being used again.

[0014] 2. The first spring is used to apply an upward thrust to the compression plate, thereby reducing the reverse thrust from the foaming agent bottle on the screw rod when the compression plate is pushed upward, thereby reducing the workload when pushing the compression plate.

[0015] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

The lower end of the screw rod 3 is fixedly connected to the knob 4. The upper end of the bottle body 2 is equipped with a pressure detection mechanism 7. The pressure detection mechanism 7 consists of a transparent tube 12, an indicator plate 13, a limit ring 14, and a second spring 15. The transparent tube 12 extends downward into the bottle body 2. The lower end of the transparent tube 12 is provided with an opening that communicates with the bottle body 2. The outer end of the transparent tube 12 is provided with an indicator mark for the staff to directly observe the pressure in the foaming agent bottle. The limit ring 14 is fixedly connected to the interior of the transparent tube 12 and is located above the bottle body 2. The second spring 15 is fixedly connected to the top of the transparent tube 12. The indicator plate 13 is located in the transparent tube 12 and is slidably connected to the inner wall of the transparent tube 12. The indicator plate 13 is located between the limit ring 14 and the second spring 15. The upper end of the indicator plate 13 is fixedly connected to the lower end of the second spring 15, and is used to detect whether the air pressure in the foaming agent bottle meets the requirements for normal injection of the foaming agent. The upper end of the injection head 11 is provided with a sealing cap 6, and the inner wall of the sealing cap 6 is threadedly connected to the outer end of the bottom of the injection head 11. A connecting belt 1 is fixedly connected to the middle of the outer end of the bottle body 2, and the end of the connecting belt 1 away from the bottle body 2 is fixedly connected to the upper end of the sealing cap 6, which is used to connect the sealing cap 6 to prevent the sealing cap 6 from being lost.

[0024] Working principle: When in use, the screw rod 3 is rotated by the knob 4, so that the screw rod 3 pushes the compression plate 8 upward to compress the gas in the foam agent bottle. At the same time, the first spring 10 pushes the compression plate 8 upward to reduce the reverse thrust transmitted to the screw rod 3 by the compression plate 8. When the air pressure in the foam agent bottle is greater than the thrust applied to the indicator plate 13 by the second spring 15, the air pressure in the foam agent bottle pushes the indicator plate 13 to move upward; when the air pressure in the foam agent bottle is less than the thrust applied to the indicator plate 13 by the second spring 15, the second spring pushes the indicator plate 13 to move downward. The staff observes the position of the indicator plate 13 through the transparent tube 12 to determine whether the air pressure in the foam agent bottle meets the usage requirements. When the foam agent bottle is stored, the sealing cover 6 is rotated on the outside of the injection head 11 and cooperates with the rubber sleeve 16 to seal the output end of the injection head 11, thereby reducing the leakage rate of the gas in the foam agent bottle and delaying the usable time of the foam agent. When using the foaming agent, unscrew the sealing cap 6 from the injection head 11 and repeat the above operation to increase the air pressure in the foaming agent bottle, so that the foaming agent can be normally injected into the surface of the object, thereby realizing multiple uses of the foaming agent.

[0025] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
