Description

Technical Field

[0001] This utility model relates to the field of atomization equipment, specifically to an atomizer. Background Technology

[0002] Atomizers are common small household appliances, such as aroma diffusers and humidifiers. Existing atomizers typically include a liquid reservoir, a liquid guide, and an atomizing element. The reservoir contains essential oils, water, or aromatherapy liquid for atomization. The liquid guide extends from the lower end into the reservoir to the upper end, adhering to the lower surface of the atomizing element, thus guiding the liquid from the reservoir to the atomizing element for atomization. Existing atomizing elements typically include a vibrating plate and a ceramic electrode (piezoelectric ceramic plate) attached above the vibrating plate. When alternating current is applied to the ceramic electrode, it generates high-frequency mechanical vibration under the piezoelectric effect, thereby driving the vibrating plate to vibrate and dispersing the liquid to be atomized. However, because the ceramic electrode is only pasted or welded to the upper surface of the vibrating plate, after prolonged vibration, the vibrating plate can easily detach (partially) from the ceramic electrode, affecting the vibration effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an atomizer whose vibrating plate can maintain a good vibration effect even after long-term use.

[0004] To solve the above problems, this utility model provides an atomizer, including a liquid storage tank for storing liquid to be atomized, an atomizing element above the liquid storage tank, the atomizing element including a vibrating plate and a piezoelectric upper electrode plate attached to the upper surface of the vibrating plate, the upper electrode plate vibrates when energized, causing the vibrating plate to vibrate, a liquid guiding element is provided between the vibrating plate and the liquid storage tank to guide the liquid to be atomized in the liquid storage tank to the vibrating plate for atomization, and a piezoelectric lower electrode plate is attached to the lower surface of the vibrating plate, the lower electrode plate vibrates when energized, also causing the vibrating plate to vibrate.

[0005] Furthermore, the lower electrode plate is annular, and the liquid guiding element is inserted into the annular center gap of the lower electrode plate, with its upper end attached to the center of the lower surface of the vibrating plate.

[0006] Furthermore, the upper electrode plate is annular, and the vibrating plate has multiple vertical through holes that connect the space above and below the vibrating plate.

[0007] Furthermore, the atomizing component includes a shock-absorbing rubber sleeve that covers the vibrating plate, the upper electrode plate, and the lower electrode plate.

[0008] Furthermore, the shock-absorbing rubber sleeve has a radial through-slot, in which a power supply wire is threaded. The power supply end of the power supply wire is connected to the upper electrode plate and / or the lower electrode plate, while the power supply end passes through the through-slot to the outside of the shock-absorbing rubber sleeve.

[0009] Furthermore, it includes a power supply, wherein the power supply end of the power supply line passes through a wire through groove and is electrically connected to the power supply for drawing power.

[0010] Furthermore, the vibrating plate has a gripping portion extending radially outward on its peripheral side for gripping during the process of attaching the upper electrode plate and / or the lower electrode plate to the surface of the vibrating plate.

[0011] Furthermore, the atomizing component includes a shock-absorbing rubber sleeve that covers the vibrating plate, the upper electrode plate, and the lower electrode plate; the shock-absorbing rubber sleeve has a radial through-slot, and the pinching part is hidden in the through-slot.

[0012] Furthermore, the upper electrode sheet and / or the lower electrode sheet are ceramic electrode sheets.

[0013] Beneficial effects: The upper and lower surfaces of the vibrating plate are respectively attached with an upper electrode plate and a lower electrode plate. When either the upper or lower electrode plate is energized, it can vibrate and drive the vibrating plate to vibrate, thereby dispersing and atomizing the liquid to be atomized at the vibrating plate. After long-term use, even if the vibrating plate is detached from one of the electrode plates (partially), it can still be driven to vibrate by the other electrode plate to maintain a good vibration effect.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to specific embodiments.

[0024] See Figure 1 and Figure 2 The housing 2 of the atomizer 1 includes an upper housing 21 and a lower housing 22 fused together. A threaded through hole is opened at the center of the upper surface of the upper housing 21, which is a liquid replenishment hole 211 (see...). Figure 3 The housing 2 contains a liquid storage chamber 3 for storing the liquid to be atomized (such as water, essential oil, or aromatherapy liquid). See [link / reference]. Figure 2 and Figure 3 The upper wall of the storage tank 3 has a first through hole 31 that connects to the internal space of the tank. The first through hole 31 is aligned upwards and connected to the replenishment hole 211. The replenishment bottle 4 is as follows: Figure 1 It can be detachably screwed into the replenishment hole 211, so that the liquid can be replenished to the liquid storage tank 3 through the replenishment hole 211 and the first through hole 31.

[0025] See Figure 2 and Figure 3 The upper surface of the upper shell 21 also has an atomizing through-hole 212; the upper wall of the liquid storage tank 3 has a second through-hole 32, which is aligned upwards and connected to the atomizing through-hole 212. See Figure 2 A vibrating plate 51 is installed in the atomizing through-hole 212. A liquid-guiding strip 6 is provided between the vibrating plate 51 and the liquid storage tank 3. The lower end of the liquid-guiding strip 6 extends into the liquid storage tank 3 through the second through-hole 32, and the upper end 6 faces upward and adheres to the center of the lower surface of the vibrating plate 51. In this way, the liquid-guiding strip 6 acts as a liquid guiding component, which can continuously guide the liquid to be atomized in the liquid storage tank 3 to the lower surface of the vibrating plate 51. See Figure 6 Annular piezoelectric ceramic upper electrode 52 and annular piezoelectric ceramic lower electrode 53 are respectively attached to the upper and lower surfaces of the vibrating plate 51. Either the upper electrode 52 or the lower electrode 53 can vibrate when energized, thus causing the vibrating plate 51 to vibrate. The vibration of the vibrating plate 51 disperses and atomizes the liquid to be atomized. Multiple vertical through holes 511 are opened at the center of the vibrating plate 51. These holes 511 connect the space above and below the vibrating plate 51, and the atomized gas is discharged through these holes 511 into the atomization through-hole 212 (see...). Figure 2 The atomized particles are then discharged through the atomizing through-hole 212 and further discharged outside the atomizer 1.

[0026] See Figure 4 and Figure 5 The annular damping sleeve 54 covers the vibrating plate 51, the upper electrode plate 52, and the lower electrode plate 53 together to prevent the housing 2 from vibrating when the vibrating plate 51, the upper electrode plate 52, and the lower electrode plate 53 vibrate at high frequency. To enable the upper electrode plate 52 and the lower electrode plate 53 to vibrate while energized, see... Figure 2 and Figure 3 A control circuit board 71, serving as a controller, is provided on one side of the liquid storage tank 3. A control switch 72 is connected above the control circuit board 71, and the control switch 72 passes through the upper surface of the upper housing 21 (see...). Figure 1 (This is for user operation by pressing; a battery 8, used as a power source, is connected below the control circuit board 71. See below.) Figure 4 The shock-absorbing rubber sleeve 54 has a radial through-slot 541 for wires, and two power supply wires 9 are installed in the slot (in conjunction with...). Figure 6 (Only a portion of the power supply line 9 is shown in the attached diagram). The power supply ends 91 of the two power supply lines 9 are respectively connected to the upper electrode plate 52 and the lower electrode plate 53, while the power supply ends of the two power supply lines 9 (not shown in the diagram) pass through the wire through groove 541 to the outside of the shock-absorbing rubber sleeve 54 and are each electrically connected to the battery 8 (see Figure 8). Figure 2 In this way, when the user presses the control switch 72, the control circuit board 71 is triggered to control the battery 8 to supply power to the upper electrode plate 52 and the lower electrode plate 53 via two power supply lines 9. After the upper electrode plate 52 and the lower electrode plate 53 are powered on, they vibrate at high frequency and drive the vibrating plate 51 to vibrate at high frequency, thereby dispersing and atomizing the liquid to be atomized that was guided to the vibrating plate 51 by the liquid-guiding cotton strip 6.

[0027] In this embodiment, the vibrating plate 51, the upper electrode plate 52, the lower electrode plate 53, and the shock-absorbing rubber sleeve 54 together constitute the atomizing element 5. The upper electrode plate 52 and the lower electrode plate 53 are respectively glued to the upper and lower surfaces of the vibrating plate 51. Figure 6 The vibrating plate 51 has a gripping part 512 extending radially outward on its periphery. Production personnel can hold the gripping part 512 of the vibrating plate 51 with one hand and attach the upper electrode plate 52 and lower electrode plate 53 to the surface of the vibrating plate 51 with the other hand, facilitating operation. After covering the vibrating plate 51, upper electrode plate 52, and lower electrode plate 53 with the damping rubber sleeve 54, the gripping part 512 of the vibrating plate 51 can be placed into the wire passage groove 541 of the damping rubber sleeve 54 for reception. Figure 4As shown. In other embodiments, the upper electrode 52 and the lower electrode 53 can be connected and attached to the upper and lower surfaces of the vibrating plate 51 by spot welding. Since either the upper electrode 52 or the lower electrode 53 can vibrate when energized, thus driving the vibrating plate 51 to vibrate, the liquid to be atomized at the vibrating plate 51 is dispersed and atomized. After long-term use, even if the vibrating plate 51 is detached from one of the electrode plates (partially), it can still be driven to vibrate by the other electrode plate, maintaining a good vibration effect.

[0028] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
