Description

Fragrance spray device

technical field

The utility model relates to a spray device, in particular to a fragrance spray device.

Background technique

At present; because of the development of economy, the development of science and technology, and the continuous improvement of human civilization, people pay more and more attention to life on the material and spiritual levels, and a good living environment is the goal that people actively want to pursue. Therefore, in many offices, In the living environment where people often live, such as rooms and cars, in order to make the environment free of special odors and turbid air, to improve work efficiency and have a better mental state, air conditioners and air purifiers are usually installed to purify the air. Or eliminate indoor peculiar smells with fragrances, electric fragrance tablets, perfumes, etc. According to this, many products that can eliminate air odors on the market, such as fragrance sprayers, fragrance sprayers, etc., are launched on the market.

But existing fragrance spray device has following shortcoming at least:

1. It sets an air guide tube in the liquid container to drain the external air into the liquid container, so that the fragrance mist in the liquid container can generate lifting force to form a spray, so that the air guide tube is protruded in the liquid container, causing the introduction of external air When the liquid container is in the air duct, it will also impact the air duct and generate resistance, thereby affecting the effect of the spray; moreover, because the air duct is added in the liquid container, the structure is complicated and inconvenient to manufacture, which will only increase the cost of manufacture.

2. After the essential oil or water filled in it is atomized by the vibrator, its stains are easy to adhere to the internal components and need to be cleaned to avoid loss or affect the atomization effect. The air spray device is assembled with a complex structure and screwed parts, which makes it difficult to disassemble. For users, it is difficult to disassemble and clean.

3. It provides essential oil and water storage in a single chamber, and does not provide a storage space for replenishing liquid functions, so that the ultrasonic vibrator must vibrate a large amount of essential oil and water in a single chamber at the same time, so that vibration and atomization does not work well.

4. When the vibrator vibrates the liquid, it is very easy for the liquid to splash outwards, which will not only easily cause the loss of the liquid, but also pollute the outside of the shell, and also block the flow of mist at the spray opening path, and the effect of causing fog to drift is not good.

Therefore, based on the concept of continuous product research, improvement and innovation, the applicant actively devotes himself to research and development thinking based on years of practical experience in product development, and through countless actual design experiments, the utility model is produced.

Extending from the side, there is a flange 722 with an outer diameter smaller than the inside of the top edge of the bottom case 10, so that the flange 722 can be directly sleeved on the inside of the top edge of the bottom case 10. Accordingly, the bottom case 10 and the casing group 70 can be easily assembled. Combination, separation.

Please refer to Fig. 3, Fig. 4, Fig. 6, Fig. 8, and Fig. 9, the space between the upper cover 71 and the lower cover 72 of the casing group 70 of the present utility model defines a storage space 73 in addition to the space outside the upper cover conduit 711, The storage space 73 can contain liquid such as water, so as to store supplementary liquid.

The lower cover 72 is provided with a fixing hole 723 for installing a water valve unit 90 . The water valve unit 90 can be switched between a connected state and a closed state for guiding the liquid in the storage space 73 to the oscillation space 31 .

Because the groove seat 30 is separately provided with an air guide seat 34 and a flange 35 to provide a path for the fan 20 to deliver gas to the oscillating space 31, there is no need to set an air guide member in the oscillating space 31, so that the gas delivered to the oscillating space 31 The gas will not encounter resistance, and the liquid is replenished through the storage space 73. The volume of the oscillation space 31 can be set to be small. As long as a small amount of water and essential oils are put in, the atomization efficiency of the oscillation is fast, and the fragrance mist can be quickly generated. , while enhancing the spray effect.

The water valve unit 90 includes a valve seat 91, a control column 92, a sealing rubber 93, and a spring 94, wherein the valve seat 91 is connectable and screw-locked in the fixing hole 723, and the control column 92 is movable. On the valve seat 91, and the spring 94 is sleeved on the control column 92, the upper and lower sides of the spring 94 are pressed against, and the sealing rubber 93 is kept close to the upper opening of the valve seat 91 to prevent the liquid in the storage space 73 from flowing out of the valve seat 91 , thereby forming a water-stopping effect.

In addition, a convex part 312 is provided in the oscillation space 31. When the casing group 70 is combined with the control column 92 of the water valve unit 90 in the bottom case 10, the control column 92 is pushed upward by the convex part 312 to make the sealing rubber 93 is separated from the upper opening of the valve seat 91 to form a communication state, so that the liquid in the storage space 73 flows into the oscillation space 31; otherwise, the convex part 312 is separated from the water valve unit 90, and the water valve unit 90 is in a closed state, and the storage space 73 The liquid stops flowing.

Accordingly, when the fragrance liquid in the oscillating space 31 is filled to a predetermined height and the valve seat 91 is closed, since the storage space 73 and the water valve unit 90 have no convective effect, the liquid in the storage space 73 will not be injected into the oscillating space 31 Conversely, when the fragrance liquid in the oscillation space 31 vibrates, atomizes and sublimates to lower the water level, so that the fragrance liquid no longer closes the valve seat 91, then the liquid in the storage space 73 flows into the oscillation space 31 again, so that continuous Repeat above-mentioned actions to supplement liquid, to improve the shortcoming that existing fragrance atomizer can't replenish fragrance liquid. Since the casing group 70 of the present invention can store the fragrance liquid, the oscillation space 31 with a smaller liquid storage volume can be used to fill the fragrance liquid (water and essential oil), so the oscillation space 31 is much smaller than the storage space 73. Under the vibration of an oscillator 40 with the same power, the vibrating water molecules in a small volume space are atomized. Because the amount of atomized liquid is small, the fragrance spray can be generated instantly, and the user does not need to wait, and the atomization effect is high and fast. , the atomization effect will be better than that of the existing single large-volume liquid storage space, and the oscillation space 31 is at least smaller than the storage space 73 .

Please refer to Fig. 3, Fig. 4, Fig. 5, and Fig. 6, the utility model casing group 70 is further provided with a water retaining member 74 at the upper cover conduit 711, and the water retaining member 74 is fixed in a ring body 741. The upper cover conduit 711 and the lower side of the ring body 741 are connected with an arc-shaped water retaining portion 743 through a rib frame 742 , and several through holes 744 are formed between the rib frames 742 .

Accordingly, the water blocking member 74 can prevent the liquid in the oscillating space 31 from splashing outwards and block the spray hole 712 , and allow the mist in the upper cover duct 711 to pass through the through hole 744 and then spray out through the spray hole 712 .

But the above-mentioned person is only the preferred embodiment of the present utility model, and should not limit the scope of implementation of the present utility model with this; All should still belong to the scope that the utility model patent covers.
