Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of spray cover, especially relates to an adjustable spray cover. BACKGROUND

[0002] The spray cover is a device installed on the top of a liquid container, which can spray the liquid in the bottle in the form of fine mist. This design not only facilitates the user to use, but also better controls the amount and distribution range of the liquid.

[0003] The existing adjustable spray cover, when the user rotates the spray cover, the internal valve core is opened, the liquid is sucked in and sprayed out through the narrow nozzle. Since the nozzle aperture is extremely small, the liquid flow rate is accelerated, and the liquid is dispersed into fine droplets due to the sudden drop in air pressure at the moment of leaving the nozzle, forming a mist. By rotating the adjusting ring, different spray modes or flow levels can be switched. However, in actual use, the internal valve core of the spray cover is opened when the user rotates it, and then when the personnel adjust and switch different spray modes or flow levels by rotating the adjusting ring, since the valve core is already in the open state, part of the liquid will be pressed out under the action of the internal tank filling pressure during adjustment, resulting in unnecessary waste. SUMMARY

[0004] Therefore, the utility model provides an adjustable spray cover, which can keep the internal valve core in a closed state during adjustment of the air pressure and open the internal valve core after the adjustment is completed, thereby facilitating the user to switch different spray modes or flow levels while avoiding unnecessary waste.

DETAILED DESCRIPTION

[0020] In order to better understand the present application, the content of the present application will be further clearly described below in conjunction with examples, but the protection content of the present application is not limited to the following examples only. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without one or more of these details.

[0021] As shown in Figure 1 , 4 , including spray tank 101, the upper end of the spray tank 101 is provided with a cover 102, the outer side of the cover 102 is provided with a cover 103, the cover 103 and the cover 102 between the cover 103 and the cover 102 are provided with a spray pipe 104, the front side of the cover 103 is provided with a rotating cover 105, the rotating cover 105 is provided with a plurality of uniformly distributed nozzles, the nozzles are matched with the spray pipe 104, the inside of the cover 102 is provided with a valve body 201, the rear side of the cover 103 is provided with an adjusting column 208, the inside of the adjusting column 208 is slidably provided with a sliding rod 210, the front end of the sliding rod 210 is provided with a sliding column 203, the front end of the sliding column 203 is provided with a valve core 202, and the valve core 202 is matched with the valve body 201.

[0022] As shown in Figure 3 , 4 , the outer arc surface of the sliding column 203 is provided with a protrusion, the inside of the adjusting column 208 is provided with a fixed ring 206, the fixed ring 206 is provided with a sliding opening matched with the protrusion, the front side of the fixed ring 206 is provided with a limit sheet one 204, the front side of the fixed ring 206 is provided with a limit sheet two 205, the limit sheet one 204 and the limit sheet two 205 are matched with the protrusion, the inner wall of the adjusting column 208 is provided with a guide rail 207 matched with the sliding opening; the guide rail 207 is matched with the protrusion.

[0023] As shown in Figure 3 , 4 , the rear side of the sliding column 203 is rotatably provided with a rotating sheet, the rotating sheet and the rear end of the inside of the adjusting column 208 are provided with a tension spring 209, and the tension spring 209 is sleeved on the outside of the adjusting column 208.

[0024] As shown in Figure 1 , 2As shown, the rear end of the adjusting column 208 is provided with a toggle handle 211.

[0025] When in use, the operator rotates the rotating cover 105, causing the rotating cover 105 and the cover 103 to rotate, so that the appropriate nozzle on the rotating cover 105 is rotated to the uppermost side to correspond with the nozzle 104, thereby allowing the operator to switch between different spray modes or flow levels of nozzles.

[0026] The operator rotates the slide rod 210 by turning the handle 211, causing the slide rod 210 to rotate the connected slide column 203. This, in turn, causes the slide column 203 to slide the valve core 202 inside the valve body 201. This causes the slide column 203 to move its outer protrusion from contact with the first limiting plate 204 to contact with the second limiting plate 205. Through the cooperation of the first and second limiting plates 204, the slide column 203 rotates its outer protrusion ninety degrees. Because the tension spring 209 is in a stretched state... This causes the protrusion and slide post 203 to move backward after passing through the sliding opening when the protrusion contacts the limiting piece 205, through the rebound force of the tension spring 209. The guide rail 207 set on the adjusting post 208 guides the sliding of the protrusion and slide post 203, so that the tension spring 209 drives the valve core 202 away from the valve body 201 through the slide post 203, so that the valve body 201 opens, and then the liquid inside the spray can 101 can enter the spray pipe 104 through the valve body 201 and then spray out from the nozzle.

[0027] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, multiple evenly distributed stop patches 106 are bonded to the outer side of the rotating cover 105, and each stop patch 106 is installed in conjunction with an adjacent nozzle. During use, the appropriate nozzle can be selected by observing the stop patch 106 at the top of the rotating cover 105, which can effectively facilitate the switching of different spray modes or flow levels.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
