Description

Technical Field

[0001] The present application belongs to the technical field of nozzles, and in particular to a press-type nozzle for quantitative liquid discharge. Background Art

[0002] Existing cosmetic bottles usually use a press-type spray nozzle. When in use, by pressing the nozzle, the lotion can be sprayed out in extremely fine water particles through a high-pressure system, so that tiny droplets of lotion float in the air, thus forming a white mist, similar to the effect of natural fog.

[0003] The existing Chinese patent with publication number CN217674315U discloses a push-type spray head, which relates to a spray head, including a connecting cover, a cavity is opened on the top of the connecting cover, a pressing pump is arranged inside the cavity, a nozzle is connected to the pressing pump, the connecting cover and the nozzle are made of PP plastic, a suction tube is connected to the end of the pressing pump away from the nozzle, a limiting block is arranged on the side wall of the nozzle, a limiting ring groove for circumferential sliding of the limiting block is opened circumferentially on the side wall of the cavity, and a movable groove for up and down sliding of the limiting block is opened vertically on the side wall of the cavity, and the movable groove and the limiting ring groove are connected to each other.

[0004] The above-mentioned spray head can lock the nozzle, but the push-type spray head often cannot accurately and quantitatively control the amount of liquid pressed out when in use. Improvements are made to this problem. Summary of the invention

[0005] The purpose of the present application is to provide a push-type nozzle for quantitative liquid discharge in order to solve the above-mentioned technical problems, which can control the amount of liquid sprayed by the nozzle in a single time and improve the quantitative accuracy.

[0006] The present application provides a press-type spray head for quantitative liquid discharge, including a connection cover, a press pump, a liquid suction tube, a nozzle, and also includes:

[0007] Mobile seat;

[0008] A driving mechanism is installed on the connecting cover and is used to drive the moving seat to move;

[0009] A locking device, used for locking the driving mechanism;

[0010] The movable seat is installed inside the connecting cover and placed below the nozzle. The driving mechanism includes a screw rod. The movable seat is connected to the screw rod. The movable seat is provided with a sliding part. The connecting cover is provided with a sliding groove adapted to the sliding part.

[0011] The moving seat is driven to move by a driving mechanism to adjust the distance between the moving seat and the nozzle. When the nozzle is pressed, it is pressed against the moving seat. The amount of liquid sprayed is quantitatively controlled by the distance between the moving seat and the nozzle to improve the accuracy of the spraying amount. After the driving mechanism completes the adjustment of the movement of the moving seat, the driving mechanism is locked by a locking device to ensure that the position of the moving seat is fixed, thereby improving the accuracy and stability of the amount of liquid sprayed. The moving seat is connected to the screw rod by a threaded pair. When the screw rod rotates, the moving seat is placed in the sliding groove through the sliding part and moves. The stability of the moving seat during movement is improved by the sliding part and the sliding groove.

[0012] Furthermore, the driving mechanism further comprises:

[0013] A first gear is mounted on the end of the screw rod;

[0014] A second gear is mounted on the connecting cover and meshes with the first gear;

[0015] A third gear, mounted and connected to the second gear;

[0016] Wherein, the connection cover is provided with a bracket, the third gear is movably connected to the bracket, and the inner wall surface of the nozzle is provided with an inner tooth portion corresponding to the third gear.

[0017] The screw rod rotates with the first gear, the second gear meshes with the first gear, the third gear is coaxially connected with the second gear, the third gear meshes with the inner tooth portion, and the nozzle and the connecting cover are movably connected. When the driving mechanism adjusts the movable seat, the third gear rotates by rotating the nozzle, and the rotation of the first screw rod is realized through gear transmission.

[0018] Furthermore, the locking device comprises:

[0019] A locking member, movably mounted on the connecting cover, wherein the locking member is provided with locking teeth, and the locking teeth correspond to the first gear;

[0020] A connecting portion extending from the locking member to the outside of the connecting cover;

[0021] The handle is connected to the connecting portion and is used to control the locking member to move along the axial direction of the connecting cover.

[0022] The first gear is locked by corresponding the locking teeth on the locking piece to the first gear. The connecting part is connected between the locking piece and the handle. The locking piece is moved by acting on the handle to control the locking between the locking teeth and the first gear. When locked, the nozzle cannot rotate and can only be lowered and pressed to move along the axis. The locking piece, the connecting part and the handle are an integrated connection structure with high structural strength.

[0023] Furthermore, both ends of the handle are provided with first buckle parts, and the connecting cover is provided with second buckle parts adapted to the first buckle parts.

[0024] Both ends of the handle are connected with a first snap part, and the first snap part and the handle are integrally connected to ensure structural strength. When the locking member and the handle are locked or unlocked, the handle is placed in the connecting cover and moves, so that the first snap part and the second snap part are buckled, ensuring that the locking member can maintain stability when locked or unlocked, and ensuring stable movement or stable fixation of the movable seat.

[0025] Furthermore, the outer surface of the handle is provided with anti-slip protrusions.

[0026] The anti-skid protrusion increases the friction when the handle is moved, so that the handle can be moved more labor-savingly and conveniently, and the anti-skid protrusion is integrally connected to the handle.

[0027] Furthermore, a buffer pad is provided at the bottom of the nozzle.

[0028] The buffer pad is bonded to the bottom of the nozzle. When the nozzle is pressed, the rigid collision between the nozzle and the moving seat is reduced, and the noise generated by the collision is reduced. The buffer pad adopts a hollow structure, and the buffer pad is abutted against the connecting cover to improve the sealing performance and prevent dust, liquid, etc. from entering between the connecting cover and the nozzle.

[0029] The beneficial effects of this application are:

[0030] 1. The driving mechanism drives the moving seat to move, and the distance between the moving seat and the nozzle is adjusted. When the nozzle is pressed, it is against the moving seat. The distance between the moving seat and the nozzle is used to quantitatively control the amount of liquid sprayed, thereby improving the accuracy of the spraying amount.

[0031] 2. After the driving mechanism completes the movement and adjustment of the moving seat, the driving mechanism is locked by the locking device to ensure that the position of the moving seat is fixed and improve the accuracy and stability of the amount of liquid sprayed.

[0032] 3. The buffer pad is used to reduce the rigid collision between the nozzle and the moving seat, and at the same time reduce the noise generated by the collision. BRIEF DESCRIPTION OF THE DRAWINGS
