Description

Technical Field

[0001] This utility model relates to the field of spray pump technology, and more specifically, to a two-hole rotary spray pump. Background Technology

[0002] In existing technologies, spray pumps are a common type of cosmetic press pump. Because the sprayed liquid is relatively uniform and appears as a mist, they are mostly used for perfume spraying. Spray pumps utilize the piston movement inside the pump body when the pump head is pressed down to expel air from the pump body. When the piston is subjected to the spring force inside the pump body, the piston returns to its original position. Liquid is forced open by suction and enters the pump body through the sealing valve. When the press head is pressed down again, the sealing valve seals, and the liquid is sprayed out through the nozzle. Most existing spray pumps only have one spray hole, and the mist sprayed from the spray hole is relatively fixed, which cannot meet the user's needs for spraying in different situations. Therefore, a technical solution is needed to solve the above problems. Utility Model Content

[0022] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1-6 As shown, this embodiment discloses a two-hole rotary spray pump, including a pump core 1, a shoulder sleeve 2, an inner cover 3, and an outer cover 4. The pump core 1 is fixedly installed on the shoulder sleeve 2. The pump core 1 is provided with a connecting pipe 11. A first through hole 23 is opened at the upper end of the shoulder sleeve 2. The connecting pipe 11 passes through the first through hole 23 and the upper end of the connecting pipe 11 is connected to the inner cover 3. The inner cover 3 is provided with a liquid chamber 31 and a first channel 32. The first channel 32 is connected to the outer side wall of the inner cover 3. The liquid chamber 31 is connected to the connecting pipe 11 and the first channel 32. The inner cover 3 is provided with an installation groove 321. The installation groove 321 is located on the outer side wall of the inner cover 3 and is connected to the first channel 32. A plug 5 is installed in the installation groove 321. The plug 5 is provided with a third channel 51. The third channel 51 is connected to the first channel 32 and the outer end face of the plug 5. The plug 5 abuts against the inner side wall of the outer cover 4. The plug 5 is made of rubber and has elasticity. It can play a sealing and fitting role when in contact with the inner side wall of the outer cover 4 to prevent leakage at the plug 5.

[0024] The outer cover 4 is installed outside the inner cover 3 and is rotatably connected to the inner cover 3. The upper end face of the outer cover 4 is provided with a second through hole 45, and the upper end face of the inner cover 3 is provided with a protrusion 35. The protrusion 35 is located inside the second through hole 45. The inner wall of the second through hole 45 is provided with a first annular groove 451, and the side wall of the protrusion 35 is provided with a first annular protrusion 351 corresponding to the first annular groove 451. The inner wall of the outer cover 4 is provided with a second annular groove 46, and the inner wall of the inner cover 3 is provided with a second annular protrusion 36 corresponding to the second annular groove 46. The upper end of the outer cover 4 and the inner cover 3 are rotatably connected by the first annular groove 451 and the first annular protrusion 351. The lower end of the outer cover 4 and the inner cover 3 are rotatably connected by the corresponding engagement of the second annular groove 46 and the second annular protrusion 36, thereby achieving a stable rotatable connection between the outer cover 4 and the inner cover 3.

[0025] The outer cover 4 is provided with a first spray hole 41 and a second spray hole 42. The structures and shapes of the first spray hole 41 and the second spray hole 42 are different, and the water mist sprayed is also different to meet the needs of different users. The first spray hole 41 and the second spray hole 42 are distributed on the outer side wall of the outer cover 4. When the outer cover 4 is rotated, the first channel 32 connects to the first spray hole 41 or the second spray hole 42. The outer cover 4 is provided with two second channels 43. The two second channels 43 respectively connect the first spray hole 41 and the second spray hole 42 to the inner wall of the outer cover 4. The diameter of the second channel 43 is smaller than the diameter of the third channel 51, which can ensure that the second channel 43 can be within the range of the third channel 51 after the outer cover 4 is rotated and switched, preventing the deviation caused by tolerance. The rotation of the outer cover 4 can realize the switching of the first spray hole 41 or the second spray hole 42, and the first spray hole 41 or the second spray hole 42 can spray different water mists.

[0026] More preferably, the upper end face of the protrusion 35 is provided with an arrow 352, which is directed toward one end of the first channel 32 that connects to the outer side wall of the inner cover 3. The arrow 352 can indicate the spray hole that can be sprayed, making it convenient for the user to use.

[0027] The shoulder cover 2 is provided with two extension plates 21, which extend toward the inner cover 3. A limiting groove 22 is provided between the two extension plates 21. The inner cover 3 is provided with a limiting plate 33, which extends toward the shoulder cover 2. The limiting plate 33 is at least partially located in the limiting groove 22. When the inner cover 3 is pressed, it can form a moving guide through the limiting plate 33 and the limiting groove 22, forming a rotation limit between the inner cover 3 and the shoulder cover 2, preventing the inner cover 3 from rotating when the outer cover 4 rotates.

[0028] The inner cover 3 is provided with a limiting block 34, and the outer cover 4 is provided with a guide groove 44. The guide groove 44 is located on the inner side wall of the outer cover 4 and connects to the end face of the outer cover 4 facing the shoulder sleeve 2. The limiting block 34 is located on the outer side wall of the inner cover 3 and extends radially along the inner cover 3. The limiting block 34 is located in the guide groove 44. The angle formed by the guide groove 44 corresponds to the included angle between the first spray hole 41 or the second spray hole 42. The limiting block 34 and the guide groove 44 cooperate to limit the rotation angle of the inner cover 3.

[0029] The inner top surface of the guide groove 44 is provided with two protrusions 441. The two protrusions 441 form a first slot 442 and a second slot 443 with the two ends of the guide groove 44 respectively. When the limiting block 34 is located in the first slot 442, the first channel 32 is connected to the first nozzle 41. When the limiting block 34 is located in the second slot 443, the first channel 32 is connected to the second nozzle 42. When the limiting block 34 rotates in the guide groove 44, it can pass over the protrusions 441 and be inserted into the first slot 442 and the second slot 443. The first slot 442 and the second slot 443 can fix the outer cover 4 after rotation, and play a positioning role.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
