Abstract
Description
Technical Field
[0001] This utility model relates to the field of sprayer equipment technology, specifically to a locking sprayer. Background Technology
[0002] A sprayer is a simple and effective liquid atomizing device, widely used in household chemical cleaners, car protective products, gardening products, pet care products, furniture polishing products, and other fields, bringing great convenience to people. Its working principle involves the reciprocating motion of a wrench increasing the air pressure inside the spray bottle, thus causing the liquid to spray out; after the liquid is sprayed out, the wrench automatically returns to its original position under the action of a spring.
[0003] The variety of existing spraying equipment is increasing, with handheld sprayers being the most widely used. The applicant's earlier utility model patent, application number CN202123456842.2, discloses a novel sprayer with advantages such as lightweight design, smooth water flow in the internal pipeline, and uniform mist output. However, because the wrench is located outside the sprayer body and has no fixing device, it is easy to accidentally touch the wrench when carrying the sprayer, causing liquid to spray out. The applicant's improved utility model patent, application number 202321593848.0, discloses a portable sprayer that controls spraying by setting a safety buckle on the pressure tube to restrict its movement, making it convenient to carry. However, the safety buckle's control mode requires left and right adjustment, which is somewhat inconvenient and results in a poor user experience. Therefore, the applicant further developed a locking sprayer. Utility Model Content

An opening is provided between the top cover and the upper tube to facilitate the movement of the pressing wrench. The inner tube is characterized by having a locking bracket on the side facing the opening, and the locking bracket is slidably provided with a locking buckle. When the locking buckle moves along the length of the locking bracket until it abuts against the pressing wrench, the pressing wrench is locked.
[0007] Preferably, an upper positioning buckle is provided between the locking bracket and the inner tube body, and a fixing part matching the upper positioning buckle is provided on the side of the buckle facing the locking bracket, so that when the buckle slides to the top of the locking bracket, the upper positioning buckle and the fixing part cooperate to lock the buckle.
[0008] Preferably, a lower positioning buckle matching the fixing part is provided between the locking bracket and the inner tube body, so that when the buckle slides to the lower part of the locking bracket, the lower positioning buckle cooperates with the fixing part to lock the buckle.
[0009] Preferably, the upper positioning buckle is a raised plate, the lower positioning buckle is a raised ball, and the fixing part is a groove matching the raised plate and the raised ball.
[0010] Preferably, the locking bracket is a strip-shaped bracket, one end of which is fixedly connected to the inner tube body, and the other end is separated from the upper positioning buckle. The locking bracket is elastic and can open and close relative to the upper positioning buckle.
[0011] Preferably, the inner tube body is provided with an arc-shaped protrusion below the upper positioning buckle, and the width of the arc-shaped protrusion gradually decreases in the direction away from the upper positioning buckle.
[0012] Preferably, the latch includes a push part, a support part disposed on the top of the push part, and a latch sleeve disposed on the back of the push part and matched with the locking bracket. The latch sleeve is slidably fitted on the locking bracket. The support part extends toward the pressing wrench. The push part is provided with a thumb groove that matches the shape of a human thumb to facilitate the finger pushing the latch.
[0013] Preferably, the latch further includes a sliding groove that matches the arc-shaped protrusion, so that when the latch is pushed, the arc-shaped protrusion is placed in the sliding groove, limiting the sliding direction of the latch.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] The sprayer of this utility model locks the push-button lever by cooperating with the locking bracket to control the spraying, thus solving the problems of accidental triggering and inconvenience of carrying existing products. At the same time, the up-and-down sliding operation is simple and effectively improves the user experience. Attached Figure Description
