Description

{Spray Hole Blockage Preventing Mist Sprayer}

The present invention relates to a mist sprayer that sprays a liquid spray, such as cosmetic liquid or perfume, in the form of a mist. More specifically, it minimizes clogging of the spray hole due to residual spray liquid (cosmetic liquid) and effectively sprays a uniform mist. It relates to a mist sprayer that prevents spray holes from being clogged.

Cosmetic liquids such as foundation, sunscreen, and moisturizer can be used by applying them directly to the skin, but they are also often used by spraying them into the air as a mist.

An ultrasonic vibrator or high-pressure spray method is used to spray a liquid spray, such as cosmetic liquid, in the form of mist. Various types of mist sprayers have been introduced in the past to spray cosmetic liquid in the form of mist. In a conventional mist sprayer, after spraying mist, residual fluid often remains around the spray hole, and this residual fluid hardens over time and blocks the spray hole. In particular, conventional mist sprayers use a needle-shaped valve structure called a needle to block the supply of cosmetic liquid, but these needles did not show sufficiently satisfactory performance in terms of durability and cosmetic liquid blocking effect (see Figure 1). .

Hereinafter, the overall configuration of the anti-clogging spray hole mist sprayer according to the present invention will be described with reference to the drawings. The specific structural or functional descriptions presented through the embodiments of the present invention are merely introduced as examples for the purpose of explaining the embodiments according to the concept of the present invention, and the embodiments according to the concept of the present invention are implemented in various forms. It can be. In addition, it should not be construed as being limited to the embodiments described in this specification, and should be understood to include all changes, equivalents, and substitutes included in the spirit and technical scope of the present invention.

Figures 2 to 4 show the overall appearance of the mist sprayer according to the present invention, and Figure 5 shows a cross-sectional view of the front and rear blocks of the mist sprayer according to the present invention in an assembled state. The fluid (spray liquid, compressed air) movement path of the mist sprayer according to the present invention is formed by assembling the front block 100 and the rear block 200. Specifically, a spray hole 110 through which air and spray liquid can be sprayed to the outside is formed on the front of the front block 100, and the rear is open so that the rear block 200 can be inserted. The air supply pipe 113 formed at the bottom of the front block 100 is connected to the air pump 500, and the spray liquid supply pipe 230 formed at the top of the rear block 200 is connected to the spray liquid container 400. The spray liquid container 400 may store cosmetic liquid to be sprayed, and the spray liquid stored in the spray liquid container 400 will naturally flow into the rear block 200 through the spray liquid supply pipe 230 due to its own weight. You can. For reference, fastening and fixing between each element can be done by conventional methods such as adhesives, bolts/nuts, etc., and since the characteristic technical idea of the present invention is not limited to fastening/fixing methods, detailed description thereof will be omitted. Do this. For reference, in the present invention, the air pump 500 and the linear actuator 300 can be supplied with power by a built-in battery, but the battery is omitted in the drawing.

Referring to FIG. 5, the assembled state of the front block 100 and the rear block 200 will be examined in detail. A spray hole 110 capable of spraying the spray liquid in the form of a mist is formed on the front of the front block 100, and a space into which the protrusion 220 of the rear block 200 can be inserted is formed on the inner surface. The rear block 200 includes a base 210 and a protrusion 220 that protrudes forward from the base 210, and the base 210 of the rear block 200 is attached to the rear end of the front block 100. /Can be combined, and the protrusion 220 is inserted into the front block 100. The space between the inner surface of the front block 100 and the protrusion 220 of the rear block 200 functions as an air passage 150, which is a passage for compressed air to be used to turn the spray liquid into mist.

Furthermore, a spray liquid injection hole 240 capable of discharging the spray liquid is formed at the front of the rear block 200, that is, at the front of the protrusion 220, but the inside of the rear block 200 is empty so that the spray liquid moves. It can function as a furnace 221. A spray liquid supply pipe 230 is formed at the top of the rear block 200, which functions to provide the spray liquid flowing down from the spray liquid container 400 by its own weight to the spray liquid movement path 221. Additionally, an air supply pipe 113 is formed at the bottom of the front block 100, which functions to provide compressed air supplied from the air pump 500 to the air movement path 150. And the spray liquid movement path 221 formed on the inner surface of the rear block 200 gradually narrows toward the spray liquid injection hole 240 to form an opening and closing step 222, which is the opening and closing head 320 to be explained later. It is an element to control the supply/blocking of spray liquid by contact with.

And as shown in FIG. 4, a linear actuator 300 may be provided at the rear end of the rear block 200 to move the opening and closing head 320 forward and backward. The linear actuator 300 is connected to the opening and closing rod 310. and an element for moving the opening/closing head 320 forward and backward. The linear actuator 300 may preferably be a solenoid linear motor. More preferably, a spray amount control unit 350 may be formed to adjust the spray amount by adjusting the forward and backward distance of the opening and closing head 320.

The opening/closing head 320 may be formed of an elastic material such as rubber or silicone. Preferably, the opening/closing head 320 may be formed in a cone shape with an inclined surface, and the bottom of the cone may be attached to the end of the opening/closing rod 310. You can. Before power is supplied to the linear actuator 300, the cone-shaped opening/closing head 320 moves forward by the linear actuator 300, so that the inclined surface of the opening/closing head 320 comes into contact with the opening/closing step 222 described above. The spray liquid movement path 221 is blocked. And when power is supplied to the linear actuator 300 and driven, the opening/closing head 320 moves rearward, the spray liquid movement path 221 is opened, and the spray liquid supplied through the spray liquid supply pipe 230 is sprayed. It can flow up to Sagong (240).

Furthermore, the mist sprayer according to the present invention may further include a power device such as a battery 600 to supply power to drive the air pump 500 and the linear actuator 300. In addition, a packing 250 for an opening and closing rod may be provided at the rear end of the rear block 200, which is to ensure watertightness of the spray liquid movement path 221.

Referring to Figures 3 and 5, the spray hole 110 is an element for turning the spray liquid into mist and spraying it into the air, and the spray hole 240 for supplying the liquid spray liquid and compressed air. It is a concept that encompasses the air injection hole 111 for. The spray liquid supplied along the spray liquid movement path 221 is sprayed through the spray liquid injection hole 240, and at the same time, the compressed air supplied through the air supply pipe 113 is sprayed through the air injection hole 111. When this happens, the spray liquid becomes mist (particles) and is released into the air. Specifically, when the front block 100 and the rear block 200 are combined, the spray liquid injection hole 240 of the rear block 200 is positioned almost parallel to the spray hole 110 of the front block, The annular space between the inner peripheral surface of the spray hole 110 and the outer peripheral surface of the spray liquid injection hole 240 functions as the air injection hole 111.

With reference to Figure 6, we will look at the operating method of the mist sprayer according to the present invention. Figure 6(a) shows a non-operating state, and Figure 6(b) shows an operating state. In the state of FIG. 6(a), power is not supplied to the linear actuator 300, and the inclined surface of the cone-shaped opening and closing head 320 meets the opening and closing step 222 by the force of the spring-like elastic body 340. Upon contact, the spray liquid movement path 221 is closed. At this time, since power is not supplied to the air pump 500, no fluid flow occurs within the spray liquid movement path 221 and the air movement path 150.

When the mist sprayer is operated, power is first supplied to the air pump 500, and compressed air is supplied to the air injection hole 111 through the air supply pipe 113 and the air movement path 150, as shown in FIG. 6(b). The mist is sprayed to the outside of the sprayer. And the linear actuator 300 also operates to overcome the force of the elastic body 340 and moves the opening/closing head 320 and the opening/closing rod 310 backwards, resulting in a space between the opening/closing head 320 and the opening/closing step 222. When opened, the spray liquid is supplied to the spray liquid injection hole 240 through the spray liquid movement path 221.

When the user stops operating, the power supply to the linear actuator 300 first stops, and as a result, the opening/closing head 320 and the opening/closing rod 310 advance so that the opening/closing head 320 contacts the opening/closing step 222. By doing so, the spray liquid movement path 221 is closed. Even at this time, the power supply to the air pump 500 is maintained for a certain period of time, so the injection of compressed air through the air injection hole 111 continues. Therefore, the spray liquid remaining around the spray hole 110 can be removed from the vicinity of the spray hole 110 by compressed air, thereby eliminating the blocking phenomenon of the spray hole 110 due to hardening of the residual spray liquid. Preferably, the air pump 500 stops operating 5 to 10 seconds after the linear actuator 300 stops operating (power supply).

The linear actuator 300 may be a solenoid linear motor. When power is not supplied to the solenoid coil 330, the opening/closing rod 310 and the opening/closing head 320 move forward by the spring-like elastic body 340. When the opening and closing head 320 comes into contact with the opening and closing step 222 and supplies power to the solenoid coil 330, the solenoid overcomes the force of the elastic body 340 and opens and closes the opening and closing rod 310 and the opening and closing head 320. It is moved to the rear. Specifically, inside the linear actuator 300, an operator 360 and a stator 370 are provided with an elastic body 340 interposed therebetween. The stator 370 is fixed to the linear actuator frame 380 and operates. The ruler 360 can move forward and backward by receiving force from the solenoid coil 330. And since the operator 360 is rigidly coupled to the opening and closing rod 310, the movement of the operator 360 directly leads to the movement of the opening and closing head 320 through the opening and closing rod 310.

Figure 7 shows the configuration of the front block 100 and the rear block 200 according to the second embodiment of the present invention. A swirl guide pin 260 is formed on the outer peripheral surface of the protrusion 220 of the rear block 200, which causes compressed air flowing in the air movement path 150 to create a swirl surrounding the protrusion 220. ) It is an element that allows movement while possessing components. The movement of compressed air that passes through the air movement path 150 and is ejected through the air injection hole 111 includes a swirl component, which consists of compressed air ejected through the air injection hole 111 and the spray liquid injection hole ( 240) promotes mixing of the sprayed liquid.

Figure 8 shows an opening/closing head and a sealing structure according to a third embodiment of the present invention. The third embodiment is to improve the sealing performance of the spray liquid movement path 221, and a cylindrical elastic material may be added to the vertex of the opening and closing head 320, which is a cone-shaped elastic material. The diameter of the cylindrical elastic body is formed to be almost similar to the diameter of the spray liquid movement path 221, so that when the spray liquid movement path 221 is closed, the gap between the opening and closing step 222 and the spray liquid injection hole 240 is formed. The amount of spray liquid remaining in the space can be minimized.

Furthermore, a packing 270 for the opening and closing head is additionally installed on the edge of the opening and closing step 222 or the inner peripheral surface of the spray liquid movement path 221 between the opening and closing step 222 and the spray liquid injection hole 240. It can be provided. The packing 270 for the opening/closing head is an O-ring-shaped element made of an elastic material made of rubber or silicon, and can improve the closing performance of the spray liquid movement path 221 by contacting the inclined portion of the opening/closing head 320, which is also an elastic material. .

In addition, a spray liquid injection hole sealing needle 311 may be additionally formed at the end of the opening and closing head 320, which removes the spray liquid that may remain in the spray liquid injection hole 240 at the moment the mist sprayer stops operating. It is intended to push out the spray liquid injection hole (240). Since the residual spray liquid pushed out of the spray liquid injection hole 240 is removed by compressed air sprayed by the air injection hole 111, clogging of the air injection hole 111 by the residual spray liquid can be reliably prevented. You can.
