[0017] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. In the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance or order.

[0018] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a spray bottle 200, including a spray head 100 and a bottle body 150 connected to each other. Specifically, the spray head 100 includes a press cap 1, a connecting outer cap 2, a nozzle 3, a pump assembly 5, and a liquid guiding assembly 6 connected to the nozzle 3. The press cap 1 is engaged in the connecting outer cap 2 and is movable relative to the connecting outer cap 2. For example, pressing the press cap 1 causes it to move downward relative to the connecting outer cap 2, and stretching or pushing the press cap 1 causes it to move upward relative to the connecting outer cap 2. The nozzle 3 is disposed on the press cap 1.

[0019] Please see Figure 3 and Figure 4 The pump assembly 5 includes a pump column 51, a piston 52 disposed within the pump column 51, and a piston force transmission bracket 53. The pump column 51 has a pump chamber 511. The liquid guiding assembly 6 includes the pump chamber 511, a backflow liquid guiding cavity 61 sleeved outside the pump column 51, and a water guiding needle 62 disposed within the pump chamber 511. The water guiding needle 62 passes through the pump chamber 511 and connects the pump chamber 511 and the nozzle 3. The piston force transmission bracket 53 abuts against the piston 52 and is sleeved around the outer periphery of the water guiding needle 62. In this embodiment, the pump column 51 is partially disposed within the backflow liquid guiding cavity 61; the backflow liquid guiding cavity 61 has an inlet 611 and communicates with the pump chamber 511. Thus, when the spray bottle 200 is inverted, the liquid enters the inverted spray guiding chamber 61 from the liquid inlet 611 and flows to the pump chamber 511. After pressing the cover 1, the water guiding needle 62 guides the liquid in the pump chamber 511 to the nozzle 3 for spraying, thereby realizing the inverted spraying of the spray bottle 200.

[0020] Preferably, the liquid inlet 611 is located near the top of the bottle body 150. This allows all the liquid in the bottle body 150 to be sprayed out, achieving the effect of no liquid residue in the bottle body 150. Multiple liquid inlets 611 are provided to accelerate the entry of liquid into the pump chamber 511, increasing the spray volume and spray efficiency.

[0021] In this embodiment, the backflow guiding liquid cavity 61 is formed by a cylindrical body and a bottom cover. A connecting part is provided inside the cylindrical body to connect with the pump column 51. Preferably, a guide part is provided at the bottom of the pump column 51, which extends into the connecting part and communicates with the backflow guiding liquid cavity 61.

[0022] Furthermore, a first movable sealing ring 8 is provided inside the backspray liquid guiding cavity 61 to open and close the liquid inlet 611. When the first movable sealing ring 8 moves to the first position, the liquid inlet 611 is opened; when the first movable sealing ring 8 moves to the second position, the liquid inlet 611 is closed. In this embodiment, when the spray bottle 200 is inverted, the first movable sealing ring 8 moves from the second position to the first position under the influence of gravity to open the liquid inlet 611, allowing the liquid from the spray bottle 200 to enter the backspray liquid guiding cavity 61 from the liquid inlet 611. When the spray bottle 200 is upright, the first movable sealing ring 8 moves from the first position to the second position under the influence of gravity to close the liquid inlet 611, preventing liquid from leaking out of the liquid inlet 611. Understandably, the liquid inlet 611 and the back spray liquid guiding cavity 61 are specifically connected by an inlet channel, which allows liquid to enter the inlet channel from the liquid inlet 611 and flow into the back spray liquid guiding cavity 61. The first movable sealing ring 8 changes between the first position and the second position to open and block the inlet channel.

[0023] In this embodiment, a first fixing sealing ring 55 is provided between the piston force transmission bracket 53 and the piston 52 to prevent liquid in the pump chamber 511 from seeping through the gap between the piston 52 and the piston force transmission bracket 53. The piston force transmission bracket 53 is provided with a first flange 531, one end of the first fixing sealing ring 55 is limited by the first flange 531; the other end of the first fixing sealing ring 55 is limited by the piston 52. The first flange 531 abuts against the piston 52.

[0024] In this embodiment, a first fixing sealing ring 55 is provided between the piston force transmission bracket 53 and the piston 52 to prevent liquid in the pump chamber 511 from seeping through the gap between the piston 52 and the piston force transmission bracket 53. The piston force transmission bracket 53 is provided with a first flange 531, one end of the first fixing sealing ring 55 is limited by the first flange 531; the other end of the first fixing sealing ring 55 is limited by the piston 52. The first flange 531 abuts against the piston 52.

[0025] Furthermore, the pump body assembly 5 also includes a compression spring 54; the piston force transmission bracket 53 is provided with a second flange 532. The upper end of the compression spring 54 abuts against the second flange 532, and the lower end of the compression spring 54 abuts against the top of the pump column 51. In this way, the pressing force of pressing the cover 1 is transmitted to the piston force transmission bracket 53 and the compression spring 54, which press down simultaneously. The piston force transmission bracket 53 pushes the piston 52 through the first flange 531, and drives the water guide needle 62 to move towards the pump chamber 511.

[0026] Preferably, a first limiting ring 518 is provided at the top of the pump column 51; the first limiting ring 518 serves as a support for the compression spring 54. In this embodiment, the connecting outer cover 2 is a stepped ring cover, which includes a first ring body 21 and a second ring body 22; the second ring body 22 is close to and detachably connected to the bottle body 150; for example, the inner wall of the second ring body 22 is threadedly connected to the top of the bottle body 150. The first ring body 21 houses the compression spring 54 and the second flange 532 of the piston force transmission bracket 53. The first limiting ring 518 is engaged with the connection between the second ring body 22 and the first ring body 21; the top of the bottle body 150 abuts against the first limiting ring 518. Thus, through the first limiting ring 518, both the compression spring 54 and the pump column 51 are simultaneously supported by the connecting outer cover 2 and the bottle body 150.

[0027] Furthermore, the pump column 51 is provided with a vent 50, which is located within the range of the piston 52's vertical movement. When the press cap 1 is not pressed, the piston 52 closes the vent 50; when the press cap 1 is pressed, the piston 52 moves downward, opening the vent 50. After the spray is ejected from the nozzle 3 when the press cap 1 is pressed, the negative pressure generated by the spray bottle 200 is released through the opened vent 50.

[0028] In this embodiment, a fixed check ball 66 is provided at the bottom of the pump chamber 511. The fixed check ball 66 is used to prevent liquid from flowing backward from the pump chamber 511 out of the backflow guiding liquid cavity 61 or the bottle body 150; that is, the fixed check ball 66 allows liquid to enter the pump chamber 511 from the backflow guiding liquid cavity 61 or the bottle body 150, and prevents the liquid in the pump chamber 511 from flowing out from the water guide needle 62.

[0029] Further, please refer to Figure 6 and Figure 7 The liquid guiding assembly also includes a straw 10, which is connected to the bottom end of the backspray liquid guiding cavity 61; and the straw 10 extends from the bottom end of the backspray liquid guiding cavity 61 to the bottom end of the bottle body 150. In this way, the liquid is guided from the straw 10 into the backspray liquid guiding cavity 61, the piston 52 moves, enters the pump chamber 511, and is guided by the water guiding needle 62 to the nozzle 3 for spraying; so that the spray bottle 200 can also be used upright.

[0030] Preferably, a movable shut-off ball 101 is provided at the connection between the straw 10 and the bottom end of the backflow guiding liquid cavity 61. When the spray bottle 200 is inverted, the movable shut-off ball 101 moves under the influence of gravity to block the liquid inlet between the backflow guiding liquid cavity 61 and the bottle body 150, preventing the liquid entering the backflow guiding liquid cavity 61 from being sprayed out. When the spray bottle 200 is upright, the movable shut-off ball 101 opens the liquid inlet between the backflow guiding liquid cavity 61 and the bottle body 150. Thus, when the spray bottle 200 is upright, the liquid is guided by the straw 10 into the liquid inlet between the backflow guiding liquid cavity 61 and the bottle body 150, enters the backflow guiding liquid cavity 61, enters the pump chamber 511 through the fixed check valve ball 66, and finally the water guide needle 62 guides the liquid in the pump chamber 511 to the nozzle 3 for spraying.

[0031] It should be noted that in industrial production, some liquids may undergo chemical reactions upon contact with metal springs and metal ball valves, leading to changes in the liquid composition. Based on the properties of the liquid stored in the bottle 150, the components of the spray head 100 and the bottle 150 of this invention will be made of non-metallic materials. For example, the compression spring 54 and the straw 10 are one-piece pieces made of plastic; the fixed anti-reverse ball 66 and the movable closing ball 101 are glass spheres.

[0032] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
