Description
Technical Field
[0001] The utility model relates to the technical field of household appliances, in particular to a spray device. Background Art
[0002] Spray equipment is a device that uses ultrasonic oscillation elements to generate high-frequency vibrations to decompose liquids such as water or essential oils into fine mist and disperse it into the surrounding air, making the air moist or full of fragrance. It is suitable for various places such as homes, hotel rooms, lobbies, corridors, guest rooms, etc.
[0003] In some spray devices, liquid is attracted to the atomizing element through a cotton core. A spring is provided on the lower side of the cotton core. The spring directly pushes the cotton core upward so that the upper side of the cotton core presses against the atomizing element. However, the cotton core expands and gets stuck in the shell after absorbing liquid, and the spring sinks into the cotton core after the cotton core becomes soft. As a result, the cotton core cannot contact the atomizing element after a period of use, thereby reducing the atomization effect. Utility Model Content
[0004] The main purpose of the utility model is to provide a spray device, aiming to solve the technical problem in the prior art that the spring directly acts on the cotton core, the cotton core cannot contact the atomizing element after being used for a period of time, and the atomizing effect is reduced.
[0005] To achieve the above object, the utility model provides a spray device, comprising:
[0006] A housing, wherein a liquid storage cavity for storing liquid is disposed in the housing, an atomizing hole for spraying fine mist is disposed on the upper side of the housing, the atomizing hole is disposed on the upper side of the liquid storage cavity, an atomizing element is disposed in the atomizing hole, a slide groove is further disposed in the housing, the atomizing hole is disposed on the upper side of the slide groove, and the slide groove extends downward from the atomizing hole;
[0007] A movable bracket is slidably connected to the slide groove, and a receiving cavity is provided in the movable bracket, the upper side of the receiving cavity is open, and the lower side of the receiving cavity is connected to the liquid storage cavity;
[0008] A cotton core, which is fixed in the accommodating cavity;
[0009] A spring is connected to the shell and the movable bracket, and the spring can generate an upward force on the movable bracket so that the upper end of the cotton core is pressed against the atomizing element.
[0010] In the spray device, the cotton core is placed in the movable bracket, and the cotton core moves with the movable bracket. The spring exerts an upward force on the movable bracket to make the cotton core press upward against the atomizing element. Since the cotton core is placed in the movable bracket, the cotton core only expands in the movable bracket after absorbing liquid and will not get stuck in the shell. The spring does not directly act on the cotton core and will not sink into the cotton core. The connection between the shell, the movable bracket and the spring remains basically unchanged, so that the cotton core can still press against the atomizing element after long-term use, and a good atomization effect can be maintained.
[0011] Preferably, a first limiting ring is provided on the inner side of the lower side of the slide groove, the movable bracket is arranged in the inner hole of the first limiting ring, a second limiting ring is provided on the outer side of the upper side of the movable bracket, the second limiting ring is located on the upper side of the first limiting ring, the spring is sleeved on the outer side of the movable bracket, the lower end of the spring abuts against the first limiting ring, and the upper end of the spring abuts against the second limiting ring.
[0012] The second limiting ring of the movable bracket is located on the upper side of the first limiting ring of the slide groove, and the spring is arranged between the first limiting ring and the second limiting ring. The first limiting ring supports the lower end of the spring, and the upper end of the spring can push the second limiting ring upward, so that the spring exerts an upward force on the movable bracket and the cotton core.
[0013] Preferably, an end plate is provided at the lower end of the movable bracket, and the lower end of the cotton core abuts against the end plate. The end plate of the movable bracket supports the cotton core so that the cotton core is fixed in the movable bracket.

[0015] The notch on the lower side of the movable bracket is close to the bottom of the liquid storage chamber, that is, the lower end of the cotton core can be closer to the bottom of the liquid storage chamber. When the liquid volume drops to the bottom of the liquid storage chamber, the cotton core can still absorb the liquid, thereby improving the utilization rate of the liquid.
[0016] Preferably, an atomizing part for atomization is provided on the atomizing element, and a reflux hole is also provided on the atomizing element. The reflux hole is arranged on the periphery of the atomizing part, and the reflux hole is directly opposite to the cotton core.
[0017] After the liquid is atomized into fine mist, the fine mist may condense and deposit in the atomization hole or on the side wall of the atomization hole. When the accumulated liquid covers the atomization part, the atomization effect will be reduced. Therefore, the utility model provides a reflux hole on the periphery of the atomization part of the atomization element to make the accumulated liquid flow back to the cotton core through the reflux hole to prevent the accumulated liquid from reducing the atomization effect.
[0018] Preferably, the atomizing hole is inclined, and the reflux hole is arranged on the downwardly inclined side of the atomizing hole. When the atomizing hole is inclined, the accumulated liquid will flow and concentrate on the downwardly inclined side, so the reflux hole is arranged on the downwardly inclined side of the atomizing hole to facilitate the discharge of the accumulated liquid.

[0032] like Figures 1 to 4 As shown, a spray device includes a housing 1, a movable bracket 3, a cotton core 4 and a spring 5.
[0033] The housing 1 is provided with a liquid storage chamber 11 for storing liquid, and an atomizing hole 12 for spraying fine mist is provided on the upper side of the housing 1. The atomizing hole 12 is provided on the upper side of the liquid storage chamber 11. The atomizing hole 12 is provided with an atomizing element 2 capable of generating ultrasonic vibrations. The atomizing element 2 can be an atomizing sheet. Liquids such as water or essential oils are sprayed and diffused into the air through the atomizing hole 12 after being formed into fine mist by the atomizing sheet. The housing 1 is also provided with a chute 13. The atomizing hole 12 is provided on the upper side of the chute 13, and the chute 13 extends downward from the atomizing hole 12. In some embodiments, a liquid storage tank 17 can be provided in the housing 1, and the liquid storage chamber 11 and the chute 13 are provided in the liquid storage tank 17.
[0034] The movable bracket 3 is slidably connected to the slide groove 13, and the movable bracket 3 can slide up and down in the slide groove 13. A accommodating chamber 31 is provided in the movable bracket 3, the upper side of the accommodating chamber 31 is open, and the lower side of the accommodating chamber 31 is connected to the liquid storage chamber 11. The cotton core 4 is fixed in the accommodating chamber 31, and the cotton core 4 can absorb the liquid in the liquid storage chamber 11 and guide it to the lower side of the atomizing element 2.
[0035] The spring 5 is connected to the housing 1 and the movable bracket 3 , and the spring 5 can generate an upward force on the movable bracket 3 so that the upper end of the cotton core 4 is pressed against the atomizing element 2 .
[0036] In the present spray device, the cotton core 4 is placed in the movable bracket 3, and the cotton core 4 moves with the movable bracket 3. The spring 5 exerts an upward force on the movable bracket 3 to make the cotton core 4 press upward against the atomizing element 2. Since the cotton core 4 is placed in the movable bracket 3, the cotton core 4 only expands in the movable bracket 3 after absorbing liquid and will not get stuck in the housing 1. The spring 5 does not directly act on the cotton core 4 and will not enter the softened cotton core 4. The connection between the housing 1, the movable bracket 3 and the spring 5 remains basically unchanged, so that the cotton core 4 can still move smoothly and press against the atomizing element 2 after long-term use, and a good atomization effect can be maintained.
[0037] In some specific embodiments, referring to Figure 1 and Figure 2 A first limiting ring 14 is provided on the inner side of the lower side of the slide groove 13, the movable bracket 3 is arranged in the inner hole of the first limiting ring 14, and a second limiting ring 32 is provided on the outer side of the upper side of the movable bracket 3. The second limiting ring 32 is located on the upper side of the first limiting ring 14. The spring 5 is sleeved on the outer side of the movable bracket 3, the lower end of the spring 5 abuts against the first limiting ring 14, and the upper end of the spring 5 abuts against the second limiting ring 32.
[0038] The second limiting ring 32 of the movable bracket 3 is located on the upper side of the first limiting ring 14 of the slide groove 13, and the spring 5 is arranged between the first limiting ring 14 and the second limiting ring 32. The first limiting ring 14 supports the lower end of the spring 5, and the upper end of the spring 5 can support the second limiting ring 32 upward, so that the spring 5 exerts an upward force on the movable bracket 3 and the cotton core 4. In other embodiments, the spring 5 can be arranged beside the movable bracket 3 instead of being sleeved on the outer side of the movable bracket 3.
[0039] In some specific embodiments, referring to Figure 1 and Figure 3 The lower end of the movable bracket 3 is provided with an end plate 33, and the lower end of the cotton core 4 abuts on the end plate 33. The cotton core 4 is placed in the accommodating cavity 31, and the end plate 33 at the lower end of the movable bracket 3 supports the cotton core 4, so that the cotton core 4 is fixed in the movable bracket 3.
[0040] Furthermore, the lower end of the movable bracket 3 extends to the bottom of the liquid storage chamber 11 , the movable bracket 3 is circumferentially fixed to the slide groove 13 , the lower side of the movable bracket 3 is provided with a notch 34 facing downward, and the lower end of the cotton core 4 is at least partially disposed in the notch 34 .
[0041] The notch 34 on the lower side of the movable bracket 3 is close to the bottom of the liquid storage chamber 11, that is, the lower end of the cotton core 4 can be closer to the bottom of the liquid storage chamber 11, and the spring 5 is arranged on the outer side of the movable bracket 3 instead of being arranged at the lower end of the cotton core 4, so when the amount of liquid used drops to the bottom of the liquid storage chamber 11, the cotton core 4 can still absorb the liquid, thereby improving the utilization rate of the liquid. The outer side of the movable bracket 3 can be provided with a convex strip 35, and the chute 13 can be provided with a groove, and the convex strip 35 is arranged in the groove to cooperate with each other to realize the circumferential fixation of the movable bracket 3 and the chute 13.
[0042] In some specific embodiments, referring to Figure 2 and Figure 4 The atomizing element 2 is provided with an atomizing portion 21 for atomization, and micropores are provided in the atomizing portion 21. The liquid passes through the atomizing portion 21 at the lower side of the atomizing portion 21 to form a fine mist diffusion. The atomizing element 2 is also provided with a reflux hole 22. The reflux hole 22 is arranged on the outer periphery of the atomizing portion 21, and the reflux hole 22 is directly opposite to the cotton core 4.
[0043] After the liquid is atomized into fine mist, the fine mist may condense and deposit in the atomization hole 12 or on the side wall of the atomization hole 12. When the accumulated liquid covers the micropores of the atomization part 21, the atomization effect will be reduced. Therefore, the utility model sets a reflux hole 22 on the periphery of the atomization part 21 of the atomization element 2, so that the accumulated liquid flows back to the cotton core 4 through the reflux hole 22 to prevent the accumulated liquid from reducing the atomization effect. Furthermore, the number of the reflux holes 22 is multiple to increase the reflux effect.
[0044] Further, the atomizing hole 12 is inclined, and the reflux hole 22 is arranged on the downwardly inclined side of the atomizing hole 12. When the atomizing hole 12 is inclined, the accumulated liquid will flow and concentrate on the downwardly inclined side, so the reflux hole 22 is arranged on the downwardly inclined side of the atomizing hole 12 to facilitate the discharge of the accumulated liquid.
[0045] Furthermore, the diameter of the reflux hole 22 is 0.8-1.2 mm. The reflux hole 22 can smoothly reflux the accumulated liquid without taking up too much space at this diameter.
[0046] In some specific embodiments, referring to Figure 1 The upper side of the shell 1 is also provided with a liquid adding hole 15 connected with the liquid storage chamber 11 , and a drainage column 16 that can be inserted into the liquid bottle 6 is provided in the liquid adding hole 15 .
[0047] The liquid bottle 6 can pour liquid into the liquid storage chamber 11 from the liquid adding hole 15, but when the viscosity of the liquid in the liquid bottle 6 is relatively large and the tension is relatively large, when the liquid bottle 6 is turned over to pour the liquid, the liquid in the liquid bottle 6 may not flow downward out of the liquid bottle 6 into the liquid storage chamber 11 due to the tension. Therefore, when the bottle mouth of the liquid bottle 6 is inserted into the liquid adding hole 15, the drainage column 16 can be inserted into the liquid bottle 6 and contact the liquid, so that the liquid can flow out of the liquid bottle 6 and enter the liquid adding hole 15 along the drainage column 16, so as to prevent the liquid in the liquid bottle 6 from being unable to flow out of the liquid bottle 6 due to the tension. The bottle mouth of the liquid bottle 6 can be inserted into the liquid adding hole 15 and threaded or clamped.
[0048] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
