Description

TECHNICAL FIELD

[0001] The present application relates to the field of sprayers, in particular to a portable sprayer. BACKGROUND

[0002] Sprayers are widely used in agriculture, horticulture, cleaning, disinfection and other fields. In agriculture, sprayers are an important tool for preventing and controlling pests and diseases; in horticulture, sprayers can be used for watering, fertilizing and other operations; in the field of cleaning and disinfection, sprayers can be used to spray disinfectants, cleaning agents and the like. Sprayers use air suction to turn liquid medicine or other liquids into mist and uniformly spray them onto other objects. A sprayer is composed of a shell, a compressed air device, a thin tube, a nozzle and a switch.

[0003] The sprayer switch is in the closed state when not working and is opened only when working, but the existing sprayer switch always needs to be pressed in the handle direction when working to be in the open state, so the operator has to work very hard and the labor intensity is large; on the other hand, since the wrench is pressed for a long time, it is easy to be damaged, has a short service life, and directly affects the performance of the sealing mechanism. CONTENT OF THE UTILITY MODEL

[0004] In order to facilitate the operator to use, the present application provides a portable sprayer.

[0005] The portable sprayer provided by the present application adopts the following technical scheme:

[0006] A portable sprayer comprises a shell, a pressing plate and a sliding block, the shell is provided with a containing cavity, an outer wall of the shell is provided with a mounting port, the mounting port is communicated with the containing cavity, the pressing plate is hinged to an inner wall of the containing cavity, one end of the pressing plate extends out of the mounting port, the sliding block is slidingly connected to the pressing plate, and one end of the sliding block away from the pressing plate is used for abutting against an inner wall of the mounting port.

[0007] By adopting the above technical scheme, when the sprayer needs to be used, the pressing plate is pressed, the sliding block is slid to abut against the inner wall of the mounting port, the position of the pressing plate is fixed, the sprayer can continuously work, the operator does not need to press the pressing plate for a long time, and the operator is facilitated to use.

[0008] Preferably, one side of the pressing plate is provided with a sliding groove, and the sliding block is slidingly embedded in the sliding groove.

[0009] By adopting the above technical scheme, the sliding groove guides the sliding of the sliding block, the sliding of the sliding block is stably controlled, the operator is facilitated to move the sliding block to the correct position, and the operator is facilitated to use.

[0010] Preferably, a groove wall of the sliding groove is provided with an anti-falling groove, an outer wall of the sliding block is fixedly connected with an anti-falling block, and the anti-falling block is slidingly embedded in the anti-falling groove.

[0011] By adopting the above technical solution, the anti-detachment block is embedded in the anti-detachment groove, making it difficult for the slider to fall off the pressure plate, thus improving the stability of the slider and making it easier for operators to use.

[0012] Preferably, an anti-slip plate is fixedly connected to the end of the slider that is away from the pressure plate.

[0013] By adopting the above technical solution, the anti-slip plate increases the friction with the inner wall of the mounting opening, so that the slider is stably stuck between the pressure plate and the inner wall of the mounting opening, improving the stability of the pressure plate and making it easier for operators to use.

[0014] Preferably, it also includes a handle, which is located on the side of the pressure plate away from the slider, and the handle is fixedly connected to the outer wall of the housing.

[0015] By adopting the above technical solution, the handle makes it easier for operators to apply force to the pressure plate, thus facilitating operation.

[0016] Preferably, the end of the handle facing the pressure plate has a groove, the groove is connected to the mounting port, and the pressure plate is slidably embedded in the groove.

[0017] By adopting the above technical solution, the groove limits the movement of the pressure plate, making it easier to control the rotation of the pressure plate. The groove also protects the pressure plate and extends its service life.

[0018] Preferably, it also includes a hand-held column, the handle being located below the pressure plate, and the upper end of the hand-held column being fixedly connected to the end of the handle away from the housing.

[0019] By adopting the above technical solution, the handheld column is designed for the operator to hold, making it convenient for the operator to carry and use the sprayer.

[0020] Preferably, the end of the handheld post facing the housing is provided with a groove, and there are multiple grooves. The multiple grooves are evenly spaced along the length of the handheld post, and adjacent grooves form a protrusion. The outer wall of the protrusion and the inner wall of the groove are smoothly transitioned.

[0021] By adopting the above technical solution, the groove increases the friction between the handheld column and the operator's hand, and the smooth transition between the protrusion and the groove protects the operator's hand and makes it easier for the operator to use.

[0022] Preferably, the housing includes a bottle cap and a cap body. The upper end of the bottle cap is provided with a receiving groove and a mounting groove. The cap body is detachably connected to the upper end of the bottle cap and covers the opening of the receiving groove and the opening of the mounting groove. The groove wall of the receiving groove and the cap body form a receiving cavity. The groove wall of the mounting groove and the cap body form a mounting opening. The end of the slider away from the pressure plate abuts against the cap body.

[0023] By adopting the above technical solution, the cap and bottle cap are detachable, which facilitates the installation of the pressure plate, and the cap can be abutted by the slider.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. When the sprayer needs to be used, press the pressure plate and slide the slider so that the slider abuts against the inner wall of the installation port to fix the position of the pressure plate, ensuring that the sprayer can work continuously without the operator having to press the pressure plate for a long time, making it convenient for the operator to use;

[0026] 2. The anti-slip plate increases the friction with the inner wall of the mounting opening, making the slider stably locked between the pressure plate and the inner wall of the mounting opening, improving the stability of the pressure plate and making it easier for operators to use;

[0027] 3. The groove limits the movement of the pressure plate, making it easier to control the rotation of the pressure plate. The groove also protects the pressure plate and extends its service life. Attached Figure Description
