Such a spray device generally comprises a reservoir and an injection means coupled to the top of the reservoir to inject functional liquid stored in the reservoir. This injection means allows the injection of the functional liquid into the injection port of the injection member by the pushing action of the injection member And is injected outside through the injection port. The principle of such a spray device utilizes the movement of a functional liquid through a pressure difference, which is a conventionally known technique such as a sprayer, a hair spray, and the like.

However, the disadvantage of the conventional spray apparatus is that when the spray apparatus is tilted or sprayed in an inverted state, the inlet of the straw member becomes higher than the water surface of the functional liquid due to the inversion, It is.

However, according to the prior art reverse-discharge switching method using the plunger, the movement width is limited according to the tilting angle, and the contact area with the inner wall of the valve body is wide, so that the braking due to friction occurs and the plunger can not be moved quickly. There is a disadvantage that the reverse discharge is difficult.

In addition, if the inclination of a certain angle (threshold value) or more is ensured, opening / closing switching is performed according to the movement of the plunger, so that there is a disadvantage that immediate reversing discharge switching can not be performed in use.

Therefore, there is a need for a spray device capable of quicker and more immediate reverse discharge switching.

The present invention has been made to solve the above problems,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a spray apparatus capable of reversing discharge according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view showing an outline of an injection means S of the present invention.

The apparatus according to the present invention is composed of a storage container (not shown) in which a functional liquid is stored and a spraying means S for spraying the functional liquid by being pressed onto the storage container (not shown) (Not shown) and the injecting means S correspond to well-known technologies in general, and a detailed description thereof and drawings may be omitted.

2 is an exploded perspective view of the present invention (injection means).

1 and 2, the configuration of the valve member 6 coupled to the injection means S can be confirmed.

The valve member 6 transfers the functional liquid flowing out of the injecting means S to the injecting member (not shown). In other words, the valve member 6 injects the functional liquid discharged from the injecting member (not shown) It is understood that it plays a role of connecting or blocking.

In general, the spraying operation of the spraying member (not shown) causes the valve member 6 to be opened and the functional liquid to be sprayed. Thus, even if a detailed description is omitted, it will be appreciated by those skilled in the art.

Further, in the present specification, the functional liquid generally refers to liquids for injection such as cosmetics, medicines, and fragrances, and refers to a liquid stored in a storage container (not shown) and ejected by the ejection means S.

In addition, although it is expressed as a functional liquid, it is obvious that a gaseous functional gas such as a gas may be injected while being liquefied, or may be injected into a gaseous state.

On the other hand, the main feature of this apparatus lies in the injection means S. 2 and a sectional view showing the internal structure of the present invention (injection means), the injection means S, which is a key feature of the present invention, will be described in detail.

2 and 3, the spraying means S of the present device includes a first inflow section 1, a second inflow section 2, an outflow section 3, a central passage section 4, And a member (5).

2 and 3, the first inlet 1 includes a lower first inlet 11 and a first inlet 13 connected to the lower first inlet 11. [ to be.

The first inlet 11 is connected to the inside of a storage container (not shown) provided at a lower portion thereof and a straw member (not shown) is coupled to the first inlet 11 so that the storage container ) Inhalation of the functional liquid.

In addition, the first inlet passage 13 provides a path for allowing the functional liquid introduced through the first inlet port 11 to be moved to the central passage section 4.

Next, as shown in Figs. 2 and 3, the second inlet portion 2 includes a second side inlet portion 21 and a second inlet passage 23 connected thereto.

The second inlet 21 is connected to the inside of a storage vessel (not shown) provided below. The difference from the first inlet 11 is that the functional liquid in the storage vessel (not shown) . Accordingly, it is preferable that the formation position of the second inlet 21 is located at the upper part of the storage container (not shown).

The second inflow passage 23 provides a path for allowing the functional liquid introduced through the second inflow port 21 to be moved to the central passage section 4. [

Next, as shown in Figs. 2 and 3, the outflow section 3 includes a top outlet 31 connected to the injection port and an outflow passage 33 connected thereto.

Here, the outlet 31 is connected to the injection member (or valve member 6), that is, the injection port, and the outflow passage 33 connected to the outlet 31 is connected to the central passage portion 4 The functional liquid flowing into the first inlet portion 1 or the second inlet portion 2 and located in the central passage portion 4 moves to the outlet port 31 along the outflow passage 33, And moves through the outlet 31 to the injection port.

It is obvious that the first inflow passage 13, the second inflow passage 23 and the outflow passage 33 should be connected to the central passage portion 4 at different positions.

Next, as shown in Figs. 2 and 3, the central passage portion 4 is configured such that the first inlet passage 13, the second inlet passage 23, and the outlet passage 33 are connected to each other, And the central passage portion 4 is made hollow. This feature is related to the ball-type opening / closing member 5 described later.

Next, as shown in Figs. 2 and 3, the opening and closing member 5 is inserted into the central passage portion 4 to open the first inflow passage 13 and close the second inflow passage 23, The first inflow path 13 is closed and the second inflow path 23 is opened when the inverted path is reversed.

What is characteristic is that the opening and closing member 5 is formed in a ball shape.

Therefore, as shown in Fig. 4 (operation process of the present invention), particularly, as shown in Fig. 4 (A), through the hollow central passage portion 4 and the ball type opening / closing member 5, 5 is moved from the central passage portion 4 to the second inflow passage 23 side so that the first inflow passage 13 is opened and the second inflow passage 23 is closed so that the first inlet 11, To allow the inflow of the functional liquid.

As shown in Fig. 4 (B), at the time of reverse rotation, the gap member moves in the central passage portion 4 toward the first inflow passage 13, and the second inflow passage 23 is opened, The inflow channel 13 is closed so that the inflow of the functional liquid through the second inflow port 21 is achieved.

In particular, the above-described feature of the opening and closing member 5 made of a ball type provides an effect of enabling quick opening / closing switching compared to the conventional technique. In the conventional reverse discharge switching method using the plunger, Since the contact area with the inner wall of the central passage portion 4 is large, the braking due to the friction is generated and the plunger can not be moved quickly, so that there is a disadvantage that rapid reverse discharge is difficult. On the other hand, (5) is advantageous in that the movement of the opening / closing member (5) progresses even at a small tilt angle and the friction with the inner wall of the central passage portion (4) is small.

The ball type opening and closing member 5 is preferably made of a material having a suitable weight for rapid reversing and discharging switching. The housing (the first powder S1 and the second powder S2) constituting at least the spraying means S, It is preferable that a material having a larger weight is selected.

In order to add a quick reverse discharge effect by the ball type opening and closing member 5, the present device shows a differentiated structure of the center passage portion 4 and the opening and closing member 5, So that the movement in the central passage portion 4 is performed more quickly.

2 and 3, in the present device, the vertical passage D4v of the central passage portion 4 is larger than the horizontal diameter D4h and the horizontal diameter D4h of the central passage portion 4 becomes larger toward the center, And the horizontal diameter D4h of the center of the central passage portion 4 is 3 to 30% larger than the diameter D5 of the opening and closing member 5. [

(The orientation specification for vertical diameter (D4v) and horizontal diameter (D4h) is based on the situation in which the device is upright, unless otherwise specified in the claims.)

Concretely, through the central passage portion 4 having the ellipsoid-like hollow (the vertical diameter D4v is larger than the horizontal diameter D4h and the horizontal diameter D4h is increasing toward the center), the device has a slight inclination angle The opening and closing member 5 can be easily moved, and a quick reverse discharge switching is achieved. This is because the inclination is generated at both ends (positions where the first inlet passage 13 and the second inlet passage 23 are provided) according to the structure of the central passage portion 4, which is an ellipsoid-like type, This is because the opening and closing member 5 is moved along the inclined hollow.

The opening and closing member 5 is quickly moved in the central passage portion 4 due to the feature that the horizontal diameter D4h of the center of the central passage portion 4 is 3 to 30% larger than the diameter D5 of the opening and closing member 5 In order to prevent the first inflow passage 13 or the second inflow passage 23 from clogging, the numerical limitation (3 to 30%) is particularly effective in smoothly moving the opening / closing member 5 to be.

If the horizontal diameter D4h of the center of the central passage portion 4 is larger than the diameter D5 of the opening and closing member 5 by 5% or less, the opening and closing member 5 does not easily move in the central passage portion 4 There is a possibility that a pinching phenomenon may occur at both vertical end portions of the central passage portion 4. [

If the horizontal diameter D4h of the center of the central passage portion 4 is larger than the diameter D5 of the opening and closing member 5 by more than 30% There arises a problem that the first inflow passage 13 or the second inflow passage 23 is not completely closed. (Preferably the horizontal diameter D4h is formed to be equal to the diameter D5 of the opening and closing member 5 at both ends of the central passage portion 4)

Therefore, through the above numerical limitation (3 to 30%), the device enables rapid and stable reverse discharge.

More preferably, the horizontal diameter D4h of the center of the central passage portion 4 is formed to be 3 to 25% larger than the diameter D5 of the opening and closing member 5, more preferably 5 to 25% To 25%.

Hereinafter, additional features of the present invention will be described in detail with reference to the accompanying drawings.

2, the apparatus comprises first and second powders S1 and S2 to which the injecting means S are mutually coupled and also includes a male engaging portion 71 formed in the first powder S1 And an arm coupling part 73 formed on the second powder S2 and coupled to the male coupling part 71. [

Due to the above feature, the present device is assembled by the engagement of the male engaging portion 71 and the female engaging portion 73, and the first powder S1 and the second powder S2 are bonded together by the ultrasonic bonding, And then assembled after being assembled.

Here, the ultrasonic bonding is a bonding method in which vibration of a sound wave is transmitted to a workpiece to generate frictional heat, and the bonding surface is melted and fused through generated frictional heat. Therefore, it is preferable that the first powder S1 and the second powder S2 are made of a thermoplastic material such as a plastic synthetic resin, and the first powder S1 and the second powder S2 are melted And are firmly coupled.

With this dual assembly structure, the device can take both the advantages of ease of assembly and robustness of assembly.

On the other hand, there is a possibility that a small gap is formed at the joint portion between the first powder S1 and the second powder S2 in spite of the above-described two-piece assembly structure, and the airtightness and the waterproofness are weakened.

In order to solve this problem, the present invention has a sealing member 8 between the first powder S1 and the second powder S2 and enhances the sealing force through a unique coupling structure.

As shown in FIG. 5, the sealing member 8 will be described in detail with reference to FIG. 5, which is one embodiment of the present invention. As shown in FIG. 5, the apparatus includes a first powder S1 and a second powder S2, The first powder S1 and the second powder S2 each have an engaging protrusion 75 melted by ultrasonic waves and the closure member 8 is provided with a first powder S1 And a narrow portion 83 formed at an end portion of the insertion portion 81 to prevent the engagement protrusion 75 from separating from the insertion protrusion 75, And a control unit.

Here, the sealing member 8 is preferably made of a material which does not melt during ultrasonic bonding, and more preferably made of a material having excellent waterproofness and suitable elasticity such as rubber, synthetic rubber and the like.

The coupling protrusions 75 formed on the first powder S1 and the second powder S2 are formed by melting in the process of ultrasonic bonding the first powder S1 and the second powder S2, The first and second powder S1 and S2 and the sealing member 8 are joined to each other by solidifying the molten joint portion 75 in the insertion portion 81 .

At this time, the narrowed portion 83 serves as a stopping function so that the solidified coupling protrusion 75 does not deviate from the insertion portion 81.

5, the sealing member 8 is interposed between the first powder S1 and the second powder S2, as shown in FIG. 5 (A) do.

5B is an enlarged view of a state before the first powder S1 and the second powder S2 are melted by ultrasonic waves. Fig. 5B is an enlarged view of Fig. .

5 (C), the first powder S1 and the second powder S2 are melted through the vibration by the ultrasonic waves to generate the coupling protrusion 75. The coupling protrusion 75 is inserted into the insertion portion 81 And the process of penetration. In this state, the engaging protrusion 75 is solidified to join the first powder S1 and the sealing member 8, the second powder S2, and the sealing member 8.

Fig. 5 [D] shows a modification of the insertion portion 81 for improving the bonding force. As shown in Fig. 5 [D], the insertion portion 81 may include a first bent portion 811 bent to one side, and a second bent portion 812 bent to the other side. According to the modification, the coupling protrusion 75 (first coupling protrusion 751) of the first powder S1 and the coupling protrusion 75 (second coupling protrusion 752) of the second powder S2 are inserted And the first engaging protrusion 751 and the second engaging protrusion 752 formed by melting by ultrasonic waves can be formed integrally with each other .

The introduction of the sealing member 8 according to the modified example of Fig. 5 [D] is superior to the sealing member 8 of Figs. 5A to 5C, and in particular, the introduction of the sealing member 8 It has an advantage in that the first powder S1 and the second powder S2 are integrally bonded.
