DETAILED DESCRIPTION

[0026] Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0027] See also Figure 1 , Figure 1 The utility model provides a medical adjustable spray head device 10, comprising: a spray head 1, a central column 2, a sealing pad 3, an adjustment head 4, a fixing block 5 and a bottle body 6.

[0028] See also Figure 2 and Figure 3 , Figure 2 and Figure 3 The structure of the nozzle from two different perspectives is shown. The nozzle 1 is integrally formed and is in the shape of a hollow cone, with a relatively wide bottom and a relatively thin top.

[0029] A nozzle 11 is provided at the top (please refer to Figure 1), a spiral structure 12 and a groove 13 are provided corresponding to the nozzle 11, and the spiral structure 12 is conducive to the formation of vortex. An opening 15 is provided at the bottom end, and a limiting rib 16 is provided corresponding to the opening 15.

[0030] See also Figure 4 and Figure 5 , Figure 4 and Figure 5 The structure of the center column from two different perspectives is shown. The center column 2 is integrally formed and is provided with: a pressing column 21, a liquid hole 22, a sealing boss 23, a clamping position 24, a hook 25, a groove 26, an inner hole 27, an annular wall 28, and a groove 29.

[0031] The groove 29 is formed at the bottom of the annular wall 28 and opens at the bottom surface. In this embodiment, there are four grooves 29, which are evenly distributed on the circular surface at intervals of 90 degrees.

[0032] The nozzle 1 and the center column 2 are installed together, and the sealing of the liquid connection can be ensured by the interference fit between the opening 15 at the bottom end of the nozzle 1 and the sealing boss 23 of the center column 2, that is, the sealing boss 23 is inserted into the opening 15.

[0033] The spray head 1 and the center column 2 are snap-fitted. Specifically, the limiting ribs 16 of the spray head 1 are correspondingly matched with the snapping positions 24 of the center column 2, so that the two cannot rotate relative to each other.

[0034] See also Figure 6 , Figure 6 The sealing gasket 3 is integrally formed and is in the shape of a ring, and is provided with: a liquid through hole 31 and a sealing boss 32. The sealing boss 32 is in the shape of a ring and is symmetrical with respect to the liquid through hole 31.

[0035] The sealing gasket 3 is installed in the groove 26 of the central column 2 and can rotate along with the rotation of the central column 2 .

[0036] See also Figure 7 and Figure 8 , Figure 7 and Figure 8 The structure of the regulating head from two different perspectives is shown. The regulating head 4 is integrally formed and cylindrical, and is provided with: a large liquid through hole 41, a small liquid through hole 42, a sealing boss 43, a locking position 44, a groove 45, and a liquid inlet hole 46.

[0037] The center column 2 and the regulating head 4 are installed together and sealed by the sealing gasket 3. Specifically, the sealing boss 32 of the sealing gasket 3 is interference-fitted with the groove 26 of the center column 2, that is, the sealing boss 32 is inserted into the groove 26; and the bottom surface of the sealing gasket 3 is interference-fitted with the top surface of the regulating head 4, which can ensure the sealing of the fluid connection.

[0038] The center column 2 and the adjustment head 4 are snap-fitted. Specifically, the hook 25 of the center column 2 corresponds to the position 44 of the adjustment head 4, so that the upper part of the adjustment head 4 can be installed in the inner hole 27 of the center column 2 and will not fall out. The inner hole 27 of the center column 2 and the sealing boss 43 of the adjustment head 4 are interference-fitted, that is, the sealing boss 43 is inserted into the inner hole 27, which can ensure the sealing of the fluid connection.

[0039] It is worth mentioning that, since there is no rotation limit between the central column 2 and the adjusting head 4 , the central column 2 can rotate relative to the adjusting head 4 .

[0040] It is understandable that in this embodiment, the sealing of the fluid connection when the center column 2 and the regulating head 4 are matched together is achieved by means of a separate sealing gasket 3. In other embodiments, the sealing gasket 3 may be removed, for example: the structure of the sealing gasket 3 is integrally formed on the center column 2.

[0041] See also Fig. 9 and Fig.10 , Fig. 9 and Fig.10 The structure of the fixing block from two different perspectives is shown. The fixing block 5 is integrally formed and cylindrical, and is provided with: an outer rib 51 , a stop 52 , an inner rib 53 , an annular wall 54 , a stop opening 55 , an inner ring 56 , and a partition 57 .

[0042] The outer rib 51 protrudes upward on the partition 57 and protrudes outward from the outer side of the inner ring 56. The outer rib 51 is spaced apart from the outer side and the inner side of the annular wall to form a gear opening 55.

[0043] There are four outer ribs 51, which are evenly distributed on the circular surface at intervals of 90 degrees. The inner ribs 53 protrude inwardly from the inner side of the inner ring 56. There are three outer ribs 51, which are evenly distributed on the circular surface at intervals of 120 degrees.

[0044] The center column 2 is installed with the fixed block 5. The groove 29 of the center column 2 is matched with the gear opening 55 of the fixed block 5. It is worth mentioning that the interference between the annular wall 28 of the center column 2 and the gear opening 55 of the fixed block 5 is about 0.3 mm. This structure can ensure that the groove 29 of the center column 2 will be matched with the gear opening 55 of the fixed block 5 once every time the center column 2 rotates ninety degrees relative to the fixed block 5, which plays a role of reminding that it is in place.

[0045] The adjusting head 4 and the fixing block 5 are snap-fitted. Specifically, the limiting groove 45 of the adjusting head 4 corresponds to the inner rib 53 of the fixing block 5, so that the two cannot rotate relative to each other.

[0046] See also Fig.11 and Fig.12 , Fig.11 and Fig.12The bottle body 6 is formed in one piece and is provided with: an upper cover 61 , a liquid outlet 62 and a clamp ring 63 .

[0047] The fixing block 5 and the bottle body 6 are installed together. The liquid inlet 46 of the regulating head 4 and the liquid outlet 62 of the bottle body 6 are interference fit, that is, the liquid outlet 62 is inserted into the liquid inlet 46, which can ensure the sealing of the liquid path connection.

[0048] The fixing block 5 and the bottle body 6 are snap-fitted. Specifically, the stopper 52 of the fixing block 5 corresponds to the clamping ring 63 of the bottle body 6. It is worth mentioning that in addition to this snap-fitting, the fixing block 5 and the bottle body 6 are also bonded by glue to ensure that the fixing block 5 cannot rotate relative to the bottle body 6 under force.

[0049] See also Fig.13 and Fig.14 , Fig.13 The cross-sectional structure of the large-angle spray is shown. Fig.14 The cross-sectional structure of the small-angle spray is shown. The working principle of the medical adjustable spray head device 10 generally includes:

[0050] The medical adjustable spray head device 10 has three states: a large-angle spray state, a small-angle spray state and a closed state.

[0051] The medical adjustable spray head device 10 has four gears: the first gear corresponds to a large-angle spray state; the second gear corresponds to a closed state; the third gear corresponds to a small-angle spray state; and the fourth gear corresponds to a closed state. It can be understood that the closed state is an intermediate state between the large-angle spray state and the small-angle spray state.

[0052] It can be understood that the cooperation of the fixed block 5, the adjustment head 4 and the central column 2 constitutes a liquid circuit switch inside the medical adjustable nozzle device 10, and the rotation of the central column 2 can select the liquid circuit state and the gear position.

[0053] When the liquid circuit switch is in the first gear, the medical adjustable nozzle device 10 is in a large-angle spray state: the liquid inlet hole 46 of the regulating head 4 is connected with the liquid through hole 22 of the central column 2 via the large liquid through hole 41. Since the area of ​​the large liquid through hole 41 of the regulating head 4 is large and the internal pressure of the nozzle 1 is small, the spray angle is large. Fig.13 shown.

[0054] When the liquid circuit switch is in the third gear, the medical adjustable nozzle device 10 is in a small-angle spray state: the liquid inlet hole 46 of the regulating head 4 is connected with the liquid through hole 22 of the central column 2 via the small liquid through hole 42. Since the area of ​​the small liquid through hole 42 of the regulating head 4 is small, the internal pressure of the nozzle 1 is large, so the spray angle is small. Fig.14 shown.

[0055] When the liquid circuit switch is in the second gear or the fourth gear, the liquid inlet hole 46 of the regulating head 4 is cut off from the liquid through hole 22 of the central column 2. The liquid in the bottle body 6 cannot be sprayed out through the nozzle 11.

[0056] See also Fig.13 , rotate the central column 2, drive the nozzle 1 and the sealing ring 3 to rotate together, rotate to the first gear, and the liquid hole 22 is aligned and connected with the large liquid hole 41 of the regulating head 4 through the liquid hole 31 of the sealing ring 3.

[0057] At this time, press the center column 2 in the direction of the arrow in the figure without releasing it. Due to the pressure in the bottle body 6, the liquid will be pressed out to the liquid outlet 62 of the bottle body 6; then, the liquid will enter the liquid inlet hole 46 of the regulating head 4; then, the liquid will pass through the large liquid through hole 41 of the regulating head 4; then, the liquid will flow into the liquid through hole 31 of the sealing ring 3; then, the liquid will flow into the groove 13 of the nozzle 1 through the liquid through hole 22 of the center column 2. Since the clamping column 21 of the center column 2 is tightly matched with the bottom surface of the spiral structure 12 in the nozzle 1, the liquid can only be sprayed out from the nozzle 11.

[0058] See also Fig.14 , rotate the central column 2, drive the nozzle 1 and the sealing ring 3 to rotate together, rotate to the third gear, the liquid hole 22 is aligned and connected with the small liquid hole 42 of the regulating head 4 through the liquid hole 31 of the sealing ring 3.

[0059] At this time, press the center column 2 in the direction of the arrow in the figure without releasing it. Due to the pressure in the bottle body 6, the liquid will be pressed out to the liquid outlet 62 of the bottle body 6; then, the liquid will enter the liquid inlet hole 46 of the regulating head 4; then, the liquid will pass through the small liquid hole 42 of the regulating head 4; then, the liquid will flow into the liquid hole 31 of the sealing ring 3; then, the liquid flows into the groove 13 of the nozzle 1 through the liquid hole 22 of the center column 2. Since the clamping column 21 of the center column 2 is tightly matched with the bottom surface of the spiral structure 12 in the nozzle 1, the liquid can only be sprayed out from the nozzle 11.

[0060] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and these modifications and replacements should all fall within the scope of protection of the claims attached to the present utility model.
