Technical Field

[0001] This utility model belongs to the field of aerosol technology, specifically a gentle pressure nasal spray. Background Technology

[0002] Nasal sprays are a common drug delivery device widely used in the treatment of respiratory diseases such as allergic rhinitis and sinusitis. Traditional nasal sprays usually adopt a manual press design, which achieves atomization and spraying of liquid medicine by physically pressing the nozzle.

[0003] However, traditional sprayers lack effective anti-accidental activation mechanisms, and the liquid is prone to leakage due to accidental squeezing during carrying or storage. Whether in daily carrying, storage or use, accidental collisions, squeezing or accidental touches may trigger the press, causing the internal liquid to spray out unexpectedly, resulting in waste of medicine. Therefore, the reliability of use is lacking and needs to be improved. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example 1, by Figures 1-4 As shown, this utility model includes a spray can 1, a nozzle 2 is movably installed on the top of the spray can 1, a pressing plate 3 is fixedly sleeved on the outside of the nozzle 2, a slot 4 is opened on the outside of the pressing plate 3, and an anti-accidental contact mechanism 5 is provided on the outside of the spray can 1.

[0022] The anti-accidental contact mechanism 5 includes an L-shaped plate 51, which is fixedly connected to the outside of the spray can 1. Symmetrically distributed rotating shafts 52 are rotatably installed inside the L-shaped plate 51. The extended ends of the two rotating shafts 52 pass through the L-shaped plate 51 and are fixedly connected to full gears 53. The two full gears 53 are meshed with each other. An L-shaped rod 54 is fixedly installed on the outside of the L-shaped plate 51. A first motor 55 is fixedly installed at the lower end of the L-shaped rod 54. The drive end of the first motor 55 is fixedly connected to one of the full gears 53.

[0023] By starting the first motor 55, the full gear 53 is controlled to rotate. The full gear 53 drives the other meshing full gear 53 to move, thereby driving the rotating shaft 52 to rotate. The rotating shaft 52 then drives the half gear 59 to move.

[0024] The L-shaped plate 51 has a T-shaped groove 56 on its outside. A T-shaped block 57 is slidably installed inside the T-shaped groove 56. A double-sided toothed plate 58 is fixedly connected to one end of the T-shaped block 57. Half gears 59 are meshed on both sides of the outside of the double-sided toothed plate 58. The half gears 59 are fixedly connected to the corresponding rotating shaft 52. A fixing block 60 is fixedly connected to one end of the double-sided toothed plate 58. A connecting frame 61 is fixedly connected to the outside of the fixing block 60.

[0025] The T-block 57 slides in the T-slot 56, which drives the double-sided gear plate 58 to move. The movement of the half gear 59 then drives the double-sided gear plate 58 to move.

[0026] A second motor 62 is fixedly installed on the outside of the connecting frame 61. A threaded rod 63 is fixedly connected to the drive end of the second motor 62. The threaded rod 63 is rotatably connected inside the connecting frame 61. A transverse block 64 is threadedly sleeved on the outside of the threaded rod 63. A guide plate 65 is fixedly installed inside the connecting frame 61. The transverse block 64 is slidably sleeved on the outside of the guide plate 65.

[0027] The second motor 62 is started to control the rotation of the threaded rod 63. The rotation of the threaded rod 63 drives the transverse block 64 to move, and the transverse block 64 drives the connecting seat 66 and the fixed column 67 to move and get into the slot 4.

[0028] A connecting seat 66 is fixedly installed at the top of the transverse block 64, and a fixing post 67 is fixedly installed on the upper part of the connecting seat 66. The fixing post 67 is slidably connected inside the slot 4, and symmetrically distributed connecting rings 68 are fixedly sleeved on the outside of the fixing post 67. The opposite ends of the two connecting rings 68 are in contact with the top and bottom surfaces of the pressing plate 3.

[0029] By setting the fixing post 67 to be inserted into the slot 4, and then making the connecting ring 68 fit with the pressing plate 3, the pressing plate 3 and the nozzle 2 are pressed and fixed.

[0030] The outer fixing sleeve of the spray can 1 is provided with a connecting sleeve 7, and an electric heating ring 8 is fixedly installed inside the connecting sleeve 7.

[0031] By setting the connecting sleeve 7, it is convenient to manually hold the spray can 1, and then the electric heating ring 8 is used to effectively heat the spray can 1, thereby increasing the temperature of the liquid in the spray can 1, improving its gentleness, and making the spraying more comfortable.

[0032] Working principle: When the spray can 1 is not in use, the first motor 55 is started to control the rotation of the full gear 53. The full gear 53 drives the other meshing full gear 53 to move, which in turn drives the rotating shaft 52 to rotate. The rotating shaft 52 then drives the half gear 59 to move. The T-shaped block 57 slides in the T-shaped groove 56, which drives the double-sided toothed plate 58 to move. The movement of the half gear 59 further drives the double-sided toothed plate 58 to move. Then, the second motor 62 is started to control the rotation of the threaded rod 63. The rotation of the threaded rod 63 drives the transverse block 64 to move. The transverse block 64 drives the connecting seat 66 and the fixing post 67 to move and engage in the slot 4. Then, the connecting ring 68 is made to fit with the pressing plate 3, thereby pressing and fixing the pressing plate 3 and the nozzle 2. This fixes the nozzle 2 and the pressing plate 3, preventing accidental spraying of the liquid by accidental pressing and improving the safety and reliability of use.
