[0081] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 as well as Figure 5 As shown, the utility model provides a rotating arm type liquid spraying device, comprising:

[0082] The pump head seat 1 is used for sealing and mounting on the bottle mouth of a liquid storage bottle 7;

[0083] The pump core mechanism 2 is disposed on the pump head seat 1 and has a liquid suction end 211a and a liquid discharge end 221a. The pump core mechanism 2 draws the medicine in the liquid storage bottle 7 through the liquid suction end 211a and discharges the medicine from the liquid discharge end 221a.

[0084] The nozzle 3 includes a nozzle body 31 for the user to press and a nozzle flow channel 32 formed in the nozzle body 31. The nozzle body 31 is provided in the pump core mechanism 2, and the nozzle flow channel 32 is connected to the liquid outlet end 221a;

[0085] The liquid spraying rotating arm 4 includes a rotating arm body 41, a liquid spraying channel 42 formed in the rotating arm body 41, and a blocking member 43. The two ends of the rotating arm body 41 along its own extension direction are respectively a rotating connection end 411 and a cantilevered liquid spraying end 412. The rotating connection end 411 is rotatably provided on the nozzle starting body 31 so that the liquid spraying channel 42 is connected to the spray starting channel 32. The blocking member 43 is provided on the side of the liquid spraying channel 42 close to the spray starting channel 32;

[0086] The nozzle 5 is provided at the cantilevered liquid spraying end 412 , and has a liquid spraying hole 51 with an adjustable liquid spraying state, and the liquid spraying hole 51 is connected to the liquid spraying channel 42 ;

[0087] When the rotating arm body 41 rotates to the first preset position relative to the spray head body 31 , the blocking member 43 blocks the spray flow channel 32 , and the spray flow channel 32 is not connected to the liquid spray flow channel 42 ;

[0088] When the rotating arm body 41 rotates to the second preset position relative to the spray head body 31 , the blocking member 43 does not block the spraying flow channel 32 , and the spraying flow channel 32 is connected to the liquid spraying flow channel 42 .

[0089] In the present invention, the liquid storage bottle 7 is used to store medicine, such as nasal spray. When the pump head seat 1 is sealed and installed on the bottle mouth of the liquid storage bottle 7, the inner cavity of the liquid storage bottle 7 is in a closed state. The pump core mechanism 2 is provided on the pump head seat 1. The pump core mechanism 2 has a liquid suction end 211a and a liquid discharge end 221a. When the user applies force to the pump core mechanism 2 through the spray head 3, the pump core mechanism 2 is triggered, and the pump core mechanism 2 draws the medicine in the liquid storage bottle 7 through the liquid suction end 211a (the liquid suction end 211a can be connected to a straw) and discharges the medicine from the liquid discharge end 221a. The spray head 3 includes a main body 31 for user depressing and a spray channel 32 formed in the main body 31. The main body 31 is mounted on the pump core mechanism 2, and the spray channel 32 is connected to the liquid outlet 221a. When the user presses the main body 31 with their finger, the main body 31 moves downward relative to the pump head base 1, causing the pump core mechanism 2 to spray liquid. The liquid in the liquid storage bottle 7 flows sequentially through the liquid suction end 211a, the liquid outlet 221a, the spray channel 32, the spray channel 42, and the spray hole 51.

[0090] The main innovation of the present invention lies in the arrangement of the liquid spraying rotating arm 4, that is, the closing of the spraying flow channel 32 is achieved by rotating the liquid spraying rotating arm 4. Specifically, the liquid spraying rotating arm 4 includes a rotating arm body 41, a liquid spraying flow channel 42 formed on the rotating arm body 41, and a blocking member 43. The two ends of the rotating arm body 41 along its own extension direction are respectively a rotating connection end 411 and a cantilevered liquid spraying end 412. The rotating connection end 411 is rotatably arranged on the nozzle head body 31 to connect the liquid spraying flow channel 42 to the spraying flow channel 32. The blocking member 43 is arranged on the side of the liquid spraying flow channel 42 close to the spraying flow channel 32. When the user does not need to spray the medicine, the rotating arm body is closed. The body 41 rotates relative to the nozzle main body 31 to a first preset position, where the blocking member 43 blocks the spray channel 32, which is no longer connected to the liquid spray channel 42. When the user needs to spray the agent again, the rotating arm body 41 rotates relative to the nozzle main body 31 to a second preset position, where the blocking member 43 no longer blocks the spray channel 32, which is now connected to the liquid spray channel 42. The user can then press the nozzle 3 to spray the agent from the liquid spray hole 51 of the nozzle 5. The blocking member 43 rotates synchronously with the rotating arm body 41. For example, when the rotating arm body 41 rotates 90 degrees relative to the nozzle main body 31, the blocking member 43 rotates 90 degrees relative to the nozzle main body 31. The rotational coordination between the liquid spray rotating arm 4 and the spray head 3 can realize the blocking and opening functions of the spray flow channel 32, which can reduce the residual medicine in the liquid spray flow channel 42, so as to reduce the number of spraying times during the next use (the number of spraying times refers to the number of times the rotating arm type liquid spray device can normally spray the medicine from the beginning under specified conditions).

[0091] As a working process of the rotating arm type spray device:

[0092] S1, rotating the rotating arm body 41 relative to the spray head body 31 to a second preset position, wherein the rotation angle required from the first preset position to the second preset position is not less than 90 degrees;

[0093] S2, press the nozzle 3;

[0094] S3, the pump core mechanism 2 draws the medicine in the liquid storage bottle 7 through the liquid suction end 211a and outputs the medicine from the liquid outlet end 221a, and finally sprays it out from the nozzle 5;

[0095] S4, after use, the rotating arm body 41 is rotated to the first preset position (i.e., the starting position) relative to the spray head body 31, and the blocking member 43 blocks the spray channel 32 to prevent the medicine in the spray channel 32 from flowing into and remaining in the spray channel 42.

[0096] Therefore, the rotating arm type liquid spraying device of the present invention can realize the blocking and opening functions of the liquid spraying channel 32 by rotating the liquid spraying rotating arm 4 relative to the liquid spraying head 3, thereby playing a good antibacterial role, and can reduce the residual agent in the liquid spraying channel 42, thereby reducing the number of spraying times the next time it is used. In addition, it is convenient for users to use and store.

[0097] Further, such as Figure 5 As shown, in order to increase the spray pressure of the medicine, the spray rotating arm 4 also includes a water core 44. The water core 44 is in the shape of a long tube and is inserted into both the spray flow channel 42 and the nozzle 5. Specifically, there are multiple water cores 44, and different water cores 44 have lumens of different diameters. The user can insert one of the water cores 44 into both the spray flow channel 42 and the nozzle 5 according to their needs.

[0098] Further, such as Figure 3 and Figure 4 As shown, the rotation angle required from the first preset position to the second preset position is not less than 90 degrees. For example, the rotation angle required from the first preset position to the second preset position is 90 degrees to 270 degrees. The user can adjust the spray angle of the nozzle 5 according to their own usage habits.

[0099] Further, such as Figure 10 and Figure 11 As shown, in order to achieve the liquid spraying action, the pump core mechanism 2 includes a pump valve assembly 21 and a piston assembly 22. The pump valve assembly 21 includes a tubular cavity valve body 211 and a valve ball 212 disposed in the cavity valve body 211. The cavity valve body 211 has a hollow cavity extending along its own axis. One end of the cavity valve body 211 is disposed on the pump head seat 1, and the other end of the cavity valve body 211 constitutes the liquid suction end 211a. The piston assembly 22 is disposed in the cavity valve body 211, and a portion of the piston assembly 22 constitutes the liquid discharge end 221a. Specifically, the nozzle body 31 of the nozzle 3 is disposed at the liquid discharge end 221a, and the nozzle body 31 and the liquid discharge end 221a move up and down synchronously.

[0100] Furthermore, the piston assembly 22 includes a main column 221, a main piston 222 and a sub-piston 223. The main column 221 has a liquid outlet channel. One end of the main column 221 constitutes the liquid outlet end 221a and is connected to the nozzle body 31. The main column 221 has a limiting protrusion 221b that cooperates with the pump head seat 1 stopper; the main piston 222 can be reciprocatingly slidably arranged in the cavity valve body 211 to form a liquid storage chamber 222a with a variable volume. The main piston 222 and the limiting protrusion A first elastic return member 224 (e.g., a spring) is provided between the main column 221 and the main valve body 211. The auxiliary piston 223 includes an interconnected auxiliary piston rod 223a and an auxiliary piston head 223b. The auxiliary piston rod 223a is slidably provided in the liquid outlet channel of the main column 221. A second elastic return member 225 (e.g., a spring) is provided between the auxiliary piston head 223b and the cavity valve body 211. The auxiliary piston head 223b can be in liquid-tight contact with the main piston 222 under the action of the second elastic return member 225. When the user presses the spray head 3, the main column 221 moves downward, and the main column 221 pushes the main piston 222 downward, and the internal pressure of the liquid storage chamber 222a gradually increases. When the internal pressure of the liquid storage chamber 222a increases to a value above a preset limit, the secondary piston 223 overcomes the elastic resistance of the second elastic return member 225, and the secondary piston 223 moves downward a short distance relative to the primary piston 222 (i.e., the secondary piston 223 and the primary piston 222 are no longer in a liquid-tight fit), and the medicine in the liquid storage chamber 222a quickly flows into the liquid outlet channel of the main column 221 and then flows out from the liquid outlet end 221a. When the internal pressure of the liquid storage chamber 222a decreases to a value below the preset limit, the secondary piston 223 returns to its original position, and a liquid-tight fit is achieved again between the secondary piston 223 and the primary piston 222.

[0101] Furthermore, the cavity valve body 211 is provided with an air-injection hole 213, and an air-injection protrusion 214 is provided on the inner wall of the cavity valve body 211. The air-injection protrusion 214 is located near the air-injection hole 213. When the main piston 222 slides over the air-injection protrusion 214, the air-injection hole 213 is connected to the outside atmosphere through the gap between the main column 221 and the pump head seat 1. Specifically, when the main piston 222 moves downward relative to the cavity valve body 211 to the lowest limit position, the upper end of the main piston 222 slides and abuts against the air-injection protrusion 214. At this time, the air-injection hole 213 is connected to the outside atmosphere through the gap between the main column 221 and the pump head seat 1, thereby completing the air-injection operation of the liquid storage bottle 7.

[0102] Further, such as Figure 6 、 Figure 7 as well as Figure 8As shown, to facilitate assembly between the rotating arm body 41 and the blocking member 43, an elongated groove 45 is provided on the inner wall of the liquid spray channel 42. The blocking member 43 comprises an inserting portion 431, a stopper plate 432 disposed at one end of the inserting portion 431, a blocking protrusion 433 disposed on the end surface of the stopper plate 432, and a retaining strip 434 that engages with the elongated groove 45. The blocking protrusion 433 is used to block the liquid spray channel 32. When the rotating arm body 41 rotates to a first predetermined position relative to the spray head body 31, the blocking protrusion 433 aligns with and blocks the liquid spray channel 32. When the rotating arm body 41 rotates to a second predetermined position relative to the spray head body 31, the blocking protrusion 433 is misaligned with the liquid spray channel 32, connecting the liquid spray channel 32 to the lumen of the inserting portion 431, which in turn connects to the lumen of the water core 44.

[0103] Further, such as Figure 6 and Figure 9 As shown, to facilitate user adjustment of the rotational position of the liquid spraying rotating arm 4 relative to the spray head 3, the spray head main body 31 is provided with a first tube portion 33, and a plurality of first positioning protrusions 34 are provided on the outer peripheral wall of the first tube portion 33. The rotating arm body 41 is provided with a second tube portion 46 that rotates with the first tube portion 33. A second positioning protrusion 47 is provided on the inner peripheral wall of the second tube portion 46, and the second positioning protrusion 47 is positioned and engaged with the first positioning protrusion 34. When the rotating arm body 41 rotates from the first preset position to the second preset position relative to the spray head main body 31, a clicking sound is emitted.

[0104] Furthermore, when the rotating arm body 41 rotates to the first preset position relative to the nozzle starter body 31, in order to prevent the rotating arm body 41 from rotating and moving, the nozzle starter body 31 is provided with a positioning slot 35, and the rotating arm body 41 is provided with a holding plate 48 that engages with the positioning slot 35; when the rotating arm body 41 rotates to the first preset position relative to the nozzle starter body 31, the positioning slot 35 and the holding plate 48 are positioned and engaged.

[0105] Further, such as Figure 5 As shown, in order to improve hygiene, the rotating arm type liquid spraying device further includes a dust cap 6 , which is detachably provided on the nozzle 5 .

[0106] In summary, the present invention can achieve the function of blocking and opening the spray channel by rotating the spray arm relative to the spray head, effectively preventing bacteria. It can also reduce the amount of residual medicine in the spray channel, thus reducing the number of sprays required for the next use. In addition, it is easy for users to use and store. Therefore, the present invention effectively overcomes the various shortcomings of the existing technology and has high industrial application value.

[0107] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
