Description

Technical Field

[0001] The utility model relates to the technical field of sunscreen cream, in particular to a sunscreen pump with adjustable flow rate. Background Art

[0002] Sunscreen refers to cosmetics that contain sunscreen agents that can block or absorb ultraviolet rays to prevent the skin from getting tanned or sunburned. Based on the principle of sun protection, sunscreen can be divided into physical sunscreen and chemical sunscreen.

[0003] Sunscreens need to choose products with different SPF or PA values ​​according to the specific objects to achieve the purpose of sun protection. The working principle of sunscreen is to isolate the skin from ultraviolet rays. The main difference between sunscreen lotion and sunscreen is the physical properties. The water content of cream is generally around 60%, and it looks "thick" and paste-like; while the water content of lotion is above 70%, and it looks thinner and has fluidity. Generally speaking, lotion is more refreshing than cream because of the higher water content, but formulators can still use different oily ingredients and thickeners to adjust the "greasy" degree of cream. Therefore, it still depends on the product itself.

[0004] When applying sunscreen, traditional sunscreen is generally taken out by squeezing or pouring. However, existing equipment is not good at controlling the amount of sunscreen taken out. Sometimes when the squeezing force is too great, the internal air pressure will be too high, causing too much sunscreen to be squeezed out. It is then inconvenient to pour it back and it can only be wasted, making the device inconvenient to use and reducing the use effect of the device. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that traditional sunscreen is generally taken out by squeezing or pouring back, but the existing equipment is not good at controlling the amount of sunscreen taken out. Sometimes when the squeezing force is too large, the internal air pressure will be too large, so that the amount of sunscreen squeezed out is too large, and it is not convenient to pour it back, so it can only be wasted, making the device very inconvenient to use and reducing the use effect of the device. A sunscreen pump with adjustable flow is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sunscreen pump with adjustable flow rate, comprising a tank body and a tank cover, a sealing groove is provided at the edge of the outer surface of the tank body near the top, and the sealing groove is fit-connected with the bottom of the tank cover, an external thread groove is provided at the edge of the outer surface of the tank body near the top in a spiral direction, and the external thread groove is located above the sealing groove, an inner liner is fixedly installed near the center of the inner bottom surface of the tank body, a sealing sleeve is fixedly connected to the top of the inner liner, an opening is provided at the center of the top of the sealing sleeve, an internal thread groove is provided at the edge of the inner surface wall of the tank cover near the bottom in a spiral direction, and the internal thread groove and the external thread groove are fit-connected.

[0007] As a preferred embodiment, the top of the tank cover is rotatably connected to a twist cover via a bearing.

[0008] As a preferred embodiment, a pressing block is provided near the center of the top of the twist cover.

[0009] As a preferred implementation, a slot is provided near the center of the top of the pressing block, and a pump nozzle is snap-connected inside the slot.

[0010] As a preferred implementation, a discharge port is provided near the center of the top of the pump nozzle.

[0011] As a preferred embodiment, a central axis is fixedly connected to the bottom of the twist cover near the center, and one end of the central axis extends to the interior of the tank body.

[0012] As a preferred embodiment, a transmission screw blade is fixedly provided on the outer surface of the central shaft along the spiral direction, and the transmission screw blade penetrates the opening.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, the internal thread groove is threadedly connected with the external thread groove by rotating the tank cover, so that the tank cover and the tank body are sealed and matched, until the bottom of the tank cover is sealed and connected with the sealing groove, so that the space inside the tank body is closed, so that it is convenient to use. At the same time, opening the tank cover and the tank body can make it easy to take out the inner liner, so that the inner liner can be replaced more conveniently, thereby improving the use efficiency of the device.

[0015] 2. In the utility model, by rotating the twist cover, the twist cover drives the central axis to rotate. After one rotation, the central axis drives the metering screw to deliver the sunscreen, so that the sunscreen is discharged under the action of the metering screw, and then sprayed out through the pump nozzle and flows out of the palm through the discharge port. Therefore, when the device is in use, the amount of discharge can be controlled by rotating the twist cover, which makes the device easy to be effectively controlled and used, thereby improving the use efficiency of the device.
