Description

Technical Field

[0001] The utility model relates to the field of spray pumps, in particular to a handheld spray pump. Background Art

[0002] A spray pump is a water pump used for spraying. This type of pump generally uses pressure to spray and can be divided into manual and automatic types. Spray pumps are widely used in seedling cultivation, cosmetics, agriculture and other fields.

[0003] At present, the handheld press-type spray pumps on the market mainly include a pump head, a trigger, a stamping piston, a spray head and a tank body. When in use, the user needs to pull and press the stamping piston multiple times to pressurize the inside of the tank body. After the pressurization is completed, the water inlet pipe of the pump head and the spray head can be unblocked by pressing the trigger. At this time, the water in the tank body will be sprayed out through the water inlet pipe and the spray head under the action of pressure. It is mainly used for spraying pesticides when cultivating a small number of flower and grass seedlings.

[0004] However, when the handheld press spray pump mentioned above is in use, when the air pressure inside the tank is insufficient, it is necessary to pull and press the punch piston again to pressurize the inside of the tank, which makes it relatively inconvenient to use. Therefore, a new handheld spray pump is proposed. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a handheld spray pump to solve the technical problems mentioned in the above background technology.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0031] The following describes an embodiment of the utility model based on its overall structure.

[0032] A handheld spray pump, such as Figure 1 - Figure 5As shown, it includes a tank body 1, a pump head 6, a spray head 7 and a water suction pipe 11, the spray head 7 is installed on the top of the pump head 6, a plug-in connector 2 is sleeved on the top of the tank body 1, and a sealing gasket is installed at the end of the plug-in connector 2. When the plug-in connector 2 is sleeved on the tank body 1, the sealing gasket will contact with the top of the tank body 1 to improve the sealing performance, and a dust cover 13 is sleeved on the outside of the spray head 7;

[0033] Specifically, the pump head 6 is slidably mounted on the top of the plug-in connector 2, and a guide cylinder 8 slidably connected to the pump head 6 is installed in the bottom of the plug-in connector 2, so that when the pump head 6 slides, the guide cylinder 8 will limit the pump head 6 together with the plug-in connector 2, thereby improving the stability of the pump head 6 when sliding. A convex plate 61 is installed on the outer wall of the pump head 6. The setting of the convex plate 61 makes it convenient for the user to push the pump head 6. The top end of the suction pipe 11 is installed in the bottom of the guide cylinder 8, and a piston ring 9 slidably connected to the pump head 6 is installed at the top end of the guide cylinder 8, and a guide groove 81 communicating with the piston ring 9 and the suction pipe 11 is provided at the top end of the guide cylinder 8. , so that the medicine in the tank body 1 will be guided by the guide groove 81 in the process of entering the guide tube 8 through the water suction pipe 11, and because a steel ball 10 is provided at the top of the guide groove 81, and the diameter of the steel ball 10 is larger than the diameter of the guide groove 81, the steel ball 10 will close the top opening of the guide groove 81, so that a closed cavity is formed between the guide groove 81 and the spray head 7, so that the medicine can be retained in the cavity. When the user presses the pump head 6, causing the pump head 6 to slide into the plug-in connector 2, the space inside the cavity will be reduced, forcing the medicine in the cavity to be sprayed outward through the spray head 7 to achieve spraying;

[0034] Furthermore, a spring 12 connected to the bottom end of the pump head 6 is installed in the plug-in connector 2, so that when the pump head 6 slides toward the plug-in connector 2, the spring 12 will be squeezed. When the squeezing of the pump head 6 stops, the spring 12 will push the pump head 6 to its original position, so that the cavity between the guide groove 81 and the spray head 7 begins to expand. As the pump head 6 is reset, negative pressure is formed in the cavity. Under the action of air pressure, the medicine liquid pushes the steel ball 10 through the suction pipe 11, so that the medicine liquid smoothly enters the cavity, ensuring that the subsequent pressing of the pump head 6 can continue to spray, so that the spray pump can directly spray through the reciprocating motion of the pump head 6 during use, which is more convenient to use.

[0035] See also Figure 1 and Figure 2A limiter for limiting the angle of the plug-in connector 2 is arranged on the outside of the tank body 1, and the limiter consists of a positioning rod 3 and a connecting ear 4, wherein the positioning rod 3 is fixedly installed on the top side wall of the tank body 1, and the installation position of the positioning rod 3 is staggered with the plug-in connector 2, so that during the installation of the plug-in connector 2, the setting of the positioning rod 3 will not cause the plug-in connector 2 to be unable to be installed, and a connecting ear 4 corresponding to the positioning rod 3 is installed on the bottom side wall of the plug-in connector 2, so that during the installation of the plug-in connector 2, the connecting ear 4 is connected to the positioning rod 3, which will limit the connection angle between the plug-in connector 2 and the tank body 1, thereby preventing the plug-in connector 2 and the tank body 1 from rotating during the use of the spray pump and causing wear at the connection, thereby reducing the loss of the plug-in connector 2 and the tank body 1.

[0036] See also Figure 1 and Figure 2 When using the sprayer, the user can judge the angle of the tank body 1 by the installation position of the positioning rod 3. The end of the water suction pipe 11 located in the tank body 1 is designed to be arc-shaped, and the end of the water suction pipe 11 is located at the bottom of the inner wall of the tank body 1. When in use, the water suction pipe 11 will draw the liquid medicine in the tank body 1, and because the liquid medicine will be guided to the end of the water suction pipe 11, the liquid medicine will be smoothly sucked into the water suction pipe 11, further ensuring the extraction effect of the liquid medicine, and an air inlet valve 5 is installed on the side wall of the tank body 1.

[0037] See also Figure 2 - Figure 4 A magnetic block is embedded in the top opening of the guide groove 81, and an iron ball corresponding to the magnetic block is installed inside the steel ball 10, so that when the steel ball 10 loses thrust, the magnetic block will attract the iron ball inside the steel ball 10, causing the steel ball 10 to move to the opening position of the guide groove 81 again, ensuring that the steel ball 10 will block the opening of the guide groove 81 again after separating from the opening of the guide groove 81, ensuring that when the pump head 6 is pressed subsequently, the cavity between the guide groove 81 and the spray head 7 is in a closed state.

[0038] See also Figure 3 - Figure 5 A limiting ring 91 located in the top opening of the guide tube 8 is installed at the bottom of the piston ring 9, and the inner diameter of the limiting ring 91 is smaller than the diameter of the steel ball 10, so that when the steel ball 10 is pushed away from the opening of the guide groove 81 by the medicine liquid, the limiting ring 91 will block the steel ball 10 to prevent the distance between the steel ball 10 and the opening of the guide groove 81 from being too long to be reset, further ensuring that the steel ball 10 can be reset smoothly, and an expansion groove 92 is opened through the outer wall of the limiting ring 91, and the length of the expansion groove 92 is greater than the diameter of the steel ball 10, so that the steel ball 10 cannot completely block the limiting ring 91, ensuring that the medicine can smoothly pass through the limiting ring 91 and the piston ring 9 into the cavity.

[0039] See also Figure 2 - Figure 4 , grooves for installing the spring 12 are provided in the bottom of the plug-in connector 2 and the bottom of the pump head 6, and the two ends of the spring 12 are respectively located in the groove at the bottom of the plug-in connector 2 and the groove at the bottom of the pump head 6, so that there is space for accommodating the spring 12 in both the plug-in connector 2 and the pump head 6, so that after the pump head 6 slides, the spring 12 can still contract smoothly, ensuring that the setting of the spring 12 will not cause the pump head 6 to be unable to slide to a limited position, and the spring 12 is sleeved on the outside of the guide tube 8, so that after the spring 12 is compressed, the guide tube 8 will support the spring 12 to prevent the spring 12 from exploding outward and causing the spring 12 to affect the movement of the pump head 6.

[0040] The working principle of the utility model is as follows: when using the spray pump, first press the convex plate 61 to make the pump head 6 slide into the plug-in connector 2. At the same time, the pump head 6 will squeeze the spring 12. As the pump head 6 moves, the cavity space between the spray head 7 and the guide groove 81 is reduced, forcing the liquid medicine in the cavity to be sprayed outward through the spray head 7. Then stop pressing the convex plate 61. At this time, the spring 12 will push the pump head 6 to its original position. As the pump head 6 is reset, the cavity space begins to recover. At this time, the cavity is in a negative pressure state, causing the liquid medicine to push the steel ball 10 through the suction pipe 11 under the action of air pressure, causing the steel ball 10 to separate from the guide groove 81. At this time, the liquid medicine will enter the cavity for storage. When the pump head 6 is reset, the steel ball 10 loses the pushing pressure and will automatically reset under the action of the magnetic block and the iron ball to seal the cavity again. At this time, the user can push the convex plate 61 again to spray.
