DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 6 As shown, a nose washing bottle 10 with an adjustment function of the present invention comprises: a bottle body 11 and an opening and closing device 12. The bottle body 11 comprises: a water outlet 111 located at the top and an air outlet 112 located at the bottom. The water outlet 111 is used for the liquid in the bottle body 11 to be squeezed out to wash the nasal cavity, and the air outlet 112 is used for the bottle body 11 to be connected to the outside air so as to squeeze out the liquid in the bottle body 11 by using the outside air pressure. The opening and closing device 12 is arranged at the air outlet 112.

[0025] Specifically, the opening and closing device 12 includes: a push cylinder 121, a support cylinder 122, an adjusting member 123, a first spring 124 and a second spring 125. The support cylinder 122 is fixed to the air outlet 112. The push cylinder 121 is slidably connected to the inside of the support cylinder 122. The adjusting member 123 is arranged between the push cylinder 121 and the support cylinder 122. The two ends of the first spring 124 contact the inner side of the push cylinder 121 and one side of the adjusting member 123 respectively. The two ends of the second spring 125 contact the inner side of the support cylinder 122 and the other side of the adjusting member 123 respectively. In this way, the adjusting member 123 can be driven to move up and down when the push cylinder 121 is pushed. A through hole 1211 is formed at one end of the push cylinder 121 away from the adjusting member 123. The through hole 1211 is used for air flow. The cylinder wall of the support cylinder 122 is formed with a plurality of adjustment windows 1224 of different sizes along its circumference. The regulating window 1224 is used to connect the inside of the bottle body 11 and the through hole 1211 to achieve air flow. The regulating member 123 cooperates with the plurality of regulating windows 1224 to adjust the air flow in the bottle body 11, thereby adjusting the flow rate of the liquid in the bottle body 11 by adjusting the air flow. The regulating member 123 is pressed by the push cylinder 121 to be adjusted to an open state connecting one of the plurality of regulating windows 1224 with the through hole 1211, or is pressed by the push cylinder 121 to be adjusted to a closed state closing the plurality of regulating windows 1224 at the same time.

[0026] As a specific implementation of this scheme, a plurality of guide protrusions 1212 are formed on the circumference of the push cylinder 121, and the guide protrusions 1212 are used to guide the push cylinder 121 to slide along the support cylinder 122. A plurality of guide grooves 1221 and a plurality of guide strips 1222 are formed on the inner wall of the support cylinder 122, and the plurality of guide grooves 1221 are respectively used to cooperate with the plurality of guide protrusions 1212. The plurality of guide grooves 1221 and the plurality of guide strips 1222 are distributed at intervals. A first wedge-shaped end 1213 is formed at one end of the guide protrusion 1212. The adjustment member 123 includes a plurality of adjustment protrusions 1231 and a hollow window portion 1234 arranged along the circumference, and the plurality of adjustment protrusions 1231 are distributed at intervals, and the hollow window portion 1234 is used to connect the adjustment window 1224 and the inside of the bottle body 11. The plurality of adjustment protrusions 1231 are at least partially slidably arranged in the plurality of guide grooves 1221, respectively. That is, the plurality of adjusting protrusions 1231 can block the adjusting window 1224, while the empty window portion 1234 can expose the adjusting window 1224. When the adjusting member 123 is adjusted to the point where the empty window portion 1234 is connected to one of the plurality of adjusting windows 1224, air can flow in the bottle body 11. When the adjusting member 123 is adjusted to the point where the plurality of adjusting protrusions 1231 respectively block the plurality of adjusting windows 1224, no air can flow in the bottle body 11. The adjusting protrusion 1231 is formed with a second wedge-shaped end 1232, and the second wedge-shaped end 1232 is used to cooperate with the first wedge-shaped end 1213. The guide bar 1222 is formed with a third wedge-shaped end 1223, and the third wedge-shaped end 1223 is used to cooperate with the second wedge-shaped end 1232 to guide the adjusting protrusion 1231 into the guide groove 1221. The plurality of adjustment windows 1224 are respectively located in different guide grooves 1221, and the plurality of adjustment windows 1224 are sequentially arranged along the plurality of adjacent guide grooves 1221 and their areas are sequentially increased. That is, by adjusting the empty window portion 1234 to correspond to the plurality of adjustment windows 1224 in sequence through the adjustment member 123, since the areas of the sequentially arranged adjustment windows 1224 are sequentially increased, the flow rate of air in the bottle body 11 can be adjusted, thereby dividing the liquid flow rate of the nose washing bottle into multiple gears. During operation, the push cylinder 121 is pushed, and the push cylinder 121 pushes the second wedge-shaped end 1232 through the first wedge-shaped end 1213 to make the adjustment protrusion 1231 of the adjustment member 123 disengage from the original guide groove 1221, and at this time, the third wedge-shaped end 1223 guides the second wedge-shaped end 1232 to move to cooperate with the third wedge-shaped end 1223. At this time, the thrust applied to the push cylinder 121 is cancelled, the first wedge-shaped end 1213 moves upward, and the adjustment protrusion 1231 moves into the guide groove 1221 adjacent to the original guide groove 1221 under the guidance of the second wedge-shaped end 1232 and the action of the second spring 125 .

[0027] The guide protrusion 1212, the guide groove 1221, the guide strip and the adjustment protrusion 1231 together form a set of intermittent cam mechanisms, the basic principle of which is as follows: Figure 7 As shown, it contains the following 5 states:

[0028] 1. Initially, the user does not press the push cylinder 121, the force on the guide protrusion 1212 is 0, and the state of the cam mechanism is as shown in Figure a.

[0029] 2. When the user presses the push cylinder 121, the guide protrusion 1212 and the adjustment protrusion 1231 slide axially and move to the instantaneous state shown in Figure b.

[0030] 3. At this time, since the adjusting protrusion 1231 is subjected to the pressure of the guide protrusion 1212 and the force applied by the second spring 125 at the same time, due to the existence of the third wedge-shaped end 1223, the two combine to form an oblique upward driving force, so that the adjusting protrusion 1231 immediately changes from the instantaneous state shown in Figure b to the state shown in Figure c.

[0031] 4. When the user releases the push cylinder 121, the guide protrusion 1212 is reset, as shown in the instantaneous state in FIG. d.

[0032] 5. After the force of the guide protrusion 1212 is lost, the adjustment protrusion 1231 continues to move into the adjacent guide groove 1221 under the elastic force of the second spring 125 and the guidance of the third wedge-shaped end 1223, and reaches a stable state as shown in Figure e.

[0033] In summary, through the above-mentioned intermittent cam mechanism, each time the user presses the push cylinder 121, the adjusting member 123 performs an intermittent rotation, and the empty window portion 1234 on the adjusting member 123 is switched. When the empty window portion 1234 switches to correspond to one of the multiple adjustment windows 1224, the opening and closing device 12 is opened, and the nose wash bottle can squeeze out liquid, and when the empty window portion 1234 corresponds to adjustment windows 1224 of different areas, the liquid flow rate of the nose wash bottle is different. When the empty window portion 1234 switches to the guide groove 1221 without the adjustment window 1224, that is, when it corresponds to the groove wall of the guide groove 1221, the opening and closing device 12 is closed, and the nose wash bottle cannot squeeze out liquid.

[0034] The opening and closing device 12 of the nose washing bottle 10 with an adjustment function can adjust the water pressure of the nose washing bottle according to the needs of different users, thereby improving the comfort of the nose washing bottle for rinsing the nasal cavity.

[0035] As a specific implementation, the number of guide grooves 1221 and guide protrusions 1212 is 4. The number of adjustment protrusions 1231 is 3, and the number of adjustment windows 1224 is 1. One adjustment window 1224 is located on one side of the three adjustment protrusions 1231. In this way, the flow rate of the liquid in the nose wash bottle can be increased or decreased in sequence under the adjustment of the adjustment member 123.

[0036] Furthermore, the area ratio of the three adjustment windows 1224 is 1:(1.8-2.2):(2.8-3.2). In this way, the flow rate ratio of the liquid at different gears can be controlled, thereby setting an appropriate liquid flow rate.

[0037] Furthermore, the four guide grooves 1221, the four guide protrusions 1212, the three adjustment protrusions 1231 and the one adjustment window 1224 serve as an adjustment component. This solution is provided with two adjustment components. The two adjustment components are symmetrically arranged. The two adjustment components can be adjusted at the same time by the adjustment member 123, so that the empty window portions 1234 of the two adjustment components correspond to the same air circulation gear at the same time, and the operation is easier.

[0038] As a specific implementation, the adjusting member 123 further includes a circular baffle 1233. The outer periphery of the circular baffle 1233 fits the inner wall of the supporting tube 122 to ensure the sealing of the opening and closing device 12 as a whole, thereby preventing the liquid in the nose washing bottle from leaking out.

[0039] Specifically, a plurality of adjusting protrusions 1231 and a hollow window portion 1234 are distributed along the circumference of the circular baffle 1233. One side of the circular baffle 1233 contacts the first spring 124 and the other side contacts the second spring 125. A plurality of adjusting protrusions 1231 and a hollow window portion 1234 are formed on the side of the circular baffle 1233 for contacting the first spring 124.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
