Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, specifically a sprayer with good sealing performance. Background Technology

[0002] In agricultural production, horticultural maintenance, and disease prevention, sprayers are widely used and indispensable as a common liquid spraying tool. However, traditional sprayers have many problems in their design and use, especially liquid leakage, which not only wastes resources but may also pollute the environment and even affect the safety of users.

[0003] According to a search, Chinese patent document CN217806441U discloses a press-type sprayer for dry cleaning mousse, comprising a bottle body with a threaded connector at the upper center. A press-type head is located at the upper center of the connector. Fixing blocks are fixedly mounted on both sides of the press-type head. A groove is formed on one side wall of each of the two fixing blocks, and a protrusion is slidably mounted inside each of the two grooves. A baffle is fixedly connected between the two protrusions. A fixing tube is located inside the bottle body, and a first feeding tube is located inside the press-type head. A second feeding tube is located in the middle of the fixing tube. The lower end of the first feeding tube is fixedly connected to the second feeding tube. A third feeding tube is fixedly connected to the inner side wall of the second feeding tube, and round holes are formed on both sides of the lower end of the outer wall of the third feeding tube. This invention provides a dustproof protection function for the spray head in a press-type sprayer for dry cleaning mousse.

[0004] However, the above technology still has some shortcomings. For example, although there is a connector in the middle of the upper part of the bottle, the gap in the threaded connection itself, as well as the influence of factors such as vibration and temperature changes during use, make it easy for the liquid to overflow from the threaded connection, which leads to a decrease in the sealing performance of the device. This not only wastes the liquid but may also pollute the environment and even cause safety hazards. To address these issues, we provide a sprayer with good sealing performance. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a sprayer with good sealing performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sprayer with good sealing performance, comprising a spray bottle and a connecting pipe, wherein the top of the spray bottle is threadedly connected to the bottom of the connecting pipe, and a water tank is fixedly connected to the top of the connecting pipe; a connecting pipe is fixedly connected to one end of the water tank; a bracket is fixedly connected to the top of the water tank, and a pressing handle is rotatably connected to one end of the bracket; a sealing mechanism is provided at one end of the connecting pipe, and a nozzle is fixedly connected to one end of the sealing mechanism; a cap is rotatably connected to the outer wall of the nozzle; two fixing blocks are fixedly connected to the outer wall of the cap, and each fixing block has an insertion mechanism inserted inside it.

[0007] The sealing mechanism described above includes a threaded block, a threaded sleeve, a first insert ring, a second insert ring, a first rubber pad, and a second rubber pad. One end of the threaded block is fixedly connected to one end of the first insert ring and the second insert ring, respectively, and the other ends of the first insert ring and the second insert ring are respectively attached to one end of the first rubber pad and the second rubber pad. The outer wall of the threaded block is threadedly connected to the inner wall of the threaded sleeve.

[0008] As described above, a reinforcing ring and a sealing ring are fixedly connected to the outer wall of the threaded block, one end of the sealing ring is in contact with one end of the threaded sleeve, and the other end of the sealing ring is fixedly connected to one end of the reinforcing ring.

[0009] As described above, the threaded sleeve has a slot 1 and a slot 2 respectively inside, and the outer walls of the insert ring 1 and the insert ring 2 are respectively inserted into the interior of the slot 1 and the slot 2.

[0010] The aforementioned insertion mechanism includes an insertion block, a guide block, a spring, and a pull rod. The two sides of the insertion block are respectively fixedly connected to one side of the two guide blocks, and one end of the insertion block is respectively fixedly connected to one end of the spring and the pull rod.

[0011] As described above, the end of the insert block away from the pull rod is inserted into the interior of the fixing block, and the end of the guide block away from the insert block is slidably connected to the mounting block.

[0012] As described above, the bottom end of the mounting block is fixedly connected to the outer wall of the nozzle, and a drive ring is fixedly connected to the end of the pull rod away from the insertion block.

[0013] Compared with existing technologies, this sprayer with good sealing performance has the following beneficial effects:

[0014] I. This utility model, through its sealing mechanism, uses a rotating threaded sleeve to connect it to the threaded block. Simultaneously, insert ring one and insert ring two enter slot one and slot two respectively, and rubber pad one and rubber pad two seal slot one and slot two. Then, the threaded sleeve compresses and tightly adheres to the sealing ring on the outside of the threaded block. At the same time, a reinforcing ring reinforces and seals the connection between the threaded sleeve and the threaded block. This allows the sealing mechanism to provide a double seal, both internally and externally, at the connection between the threaded block and the threaded sleeve, preventing liquid from leaking out of the device and enhancing its sealing performance.

[0015] II. This utility model, through its plug-in mechanism, allows the cap to be flipped after spraying. Then, the drive ring is pulled to both sides, causing it to move the plug block via a pull rod. The cap then tightens around the nozzle. Finally, the drive ring is released, and the plug block automatically returns to its original position under spring pressure. This ensures a tight seal between the cap and the nozzle outlet, effectively preventing leakage and evaporation of the sprayed liquid, maintaining the uniformity and effectiveness of the spray, and avoiding waste. Furthermore, a plug-in mechanism is also provided above the nozzle to fix the cap's position during operation, preventing it from affecting the nozzle's spray range.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-6 As shown, this utility model provides a technical solution: a sprayer with good sealing performance, including a spray bottle 1 and a connecting pipe 2. The top of the spray bottle 1 is threadedly connected to the bottom of the connecting pipe 2, and a water tank 3 is fixedly connected to the top of the connecting pipe 2. A connecting pipe 4 is fixedly connected to one end of the water tank 3, and a bracket 5 is fixedly connected to the top of the water tank 3. A pressing handle 6 is rotatably connected to one end of the bracket 5. A sealing mechanism 8 is provided at one end of the connecting pipe 4, and a nozzle 7 is fixedly connected to one end of the sealing mechanism 8. A cap 10 is rotatably connected to the outer wall of the nozzle 7. Two fixing blocks 11 are fixedly connected to the outer wall of the cap 10, and an insertion mechanism 9 is inserted into the interior of each fixing block 11.

[0026] To seal the connection between nozzle 7 and connecting pipe 4, the sealing mechanism 8 is rotated to seal the inside of the connection between nozzle 7 and connecting pipe 4. Simultaneously, the sealing mechanism 8 presses and tightly adheres to the external sealing ring 13. At the same time, the reinforcing ring 12 reinforces the connection of the sealing mechanism 8, allowing for a double seal from both inside and outside, preventing liquid from overflowing from the device and enhancing its sealing performance. Finally, after spraying, the cap 10 is flipped over, and then the drive ring 17 is pulled to both sides, causing it to return to the fixed block 11 via the insertion mechanism 9. This ensures the cap 10 tightly covers the water outlet of nozzle 7, effectively preventing leakage and evaporation of the sprayed liquid, maintaining the uniformity and effectiveness of the spray, and avoiding waste. Furthermore, an insertion mechanism 9 is also provided above nozzle 7 to fix the position of cap 10 during operation, preventing cap 10 from affecting the spray range of nozzle 7.

[0027] like Figure 1 and Figure 2 As shown, the sealing mechanism 8 includes a threaded block 801, a threaded sleeve 802, a first insert ring 803, a second insert ring 804, a first rubber pad 805, and a second rubber pad 806. One end of the threaded block 801 is fixedly connected to one end of the first insert ring 803 and the second insert ring 804, and the other ends of the first insert ring 803 and the second insert ring 804 are respectively attached to one end of the first rubber pad 805 and the second rubber pad 806. The outer wall of the threaded block 801 is threadedly connected to the inner wall of the threaded sleeve 802. A reinforcing ring 12 and a sealing ring 13 are fixedly connected to the outer wall of the threaded block 801. One end of the sealing ring 13 is attached to one end of the threaded sleeve 802, and the other end of the sealing ring 13 is fixedly connected to one end of the reinforcing ring 12. The outer wall of the threaded block 801 is fixedly connected to the reinforcing ring 12 and the sealing ring 13. One end of the sealing ring 13 is attached to one end of the threaded sleeve 802, and the other end of the sealing ring 13 is fixedly connected to one end of the reinforcing ring 12.

[0028] By rotating the threaded sleeve 802, the threaded sleeve 802 is threadedly connected to the threaded block 801. At the same time, the first insert ring 803 and the second insert ring 804 enter the first slot 14 and the second slot 15 respectively. Furthermore, the first rubber gasket 805 and the second rubber gasket 806 seal the first slot 14 and the second slot 15. Then, the threaded sleeve 802 compresses and tightly adheres to the sealing ring 13 on the outside of the threaded block 801. Meanwhile, the reinforcing ring 12 reinforces and seals the connection between the threaded sleeve 802 and the threaded block 801. This allows the sealing mechanism 8 to perform a double seal both inside and outside at the connection between the threaded block 801 and the threaded sleeve 802, preventing liquid from overflowing from the device and enhancing the sealing performance of the device.

[0029] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the insertion mechanism 9 includes an insertion block 901, a guide block 902, a spring 903, and a pull rod 904. The two sides of the insertion block 901 are fixedly connected to one side of the two guide blocks 902, and one end of the insertion block 901 is fixedly connected to one end of the spring 903 and one end of the pull rod 904. The end of the insertion block 901 away from the pull rod 904 is inserted into the interior of the fixing block 11. The end of the guide block 902 away from the insertion block 901 is slidably connected to the mounting block 16. The bottom end of the mounting block 16 is fixedly connected to the outer wall of the nozzle 7. The end of the pull rod 904 away from the insertion block 901 is fixedly connected to the drive ring 17.

[0030] After the spraying operation is completed, flip the cap 10, then pull the drive ring 17 to both sides, so that the drive ring 17 drives the insert block 901 to move through the pull rod 904. Then, the cap 10 is closed tightly over the nozzle 7. Then, the drive ring 17 is released, and the insert block 901 is automatically reset to the fixed block 11 under the pressure of the spring 903. This makes the cap 10 tightly cover the water outlet of the nozzle 7, effectively preventing leakage and evaporation of the sprayed liquid, maintaining the uniformity and effect of the spray, and avoiding waste. In addition, the nozzle 7 is also provided with an insertion mechanism 9 above it. When the nozzle 7 is working, the position of the cap 10 is fixed to prevent the cap 10 from affecting the spray range of the nozzle 7.

[0031] Working principle: To seal the connection between nozzle 7 and connecting pipe 4, the threaded sleeve 802 is rotated to connect with the threaded block 801. Simultaneously, insert ring 1 803 and insert ring 2 804 enter slot 1 14 and slot 2 15 respectively. Rubber pads 1 805 and 2 806 seal slot 1 14 and slot 2 15. Then, the threaded sleeve 802 presses against the sealing ring 13 on the outside of the threaded block 801, and the reinforcing ring 12 reinforces the seal at the connection between the threaded sleeve 802 and the threaded block 801. This allows the sealing mechanism 8 to simultaneously provide double sealing from both inside and outside at the connection between the threaded block 801 and the threaded sleeve 802. Finally, after completing the spraying operation, flip the cap 10 over, then pull the drive ring 17 to both sides, causing the drive ring 17 to move the insert block 901 via the pull rod 904. Then, the cap 10 is tightened over the nozzle 7. After that, the drive ring 17 is released, and the insert block 901 automatically returns to the fixed block 11 under the pressure of the spring 903. This ensures that the cap 10 tightly covers the water outlet of the nozzle 7, effectively preventing leakage and evaporation of the sprayed liquid, maintaining the uniformity and effect of the spray, and avoiding waste. In addition, an insertion mechanism 9 is also provided above the nozzle 7. When the nozzle 7 is working, the position of the cap 10 is fixed to prevent the cap 10 from affecting the spray range of the nozzle 7.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
