[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] Refer to the following Figure 1-Figure 15 The ultrasonic atomizing device 100 for a clothing processing device according to an embodiment of the present invention is described. The ultrasonic atomizing device 100 is used in the clothing processing device. After the dehydration or drying of the clothing processing device is completed, water or other liquids can be atomized into tiny droplets, and then combined with high-temperature air washing and other technologies, the clothes in the clothing processing device can be wrinkle-removed and smoothed. The clothing processing device can be a pulsator washing machine, a drum washing machine, a dryer, and a washer-dryer.

[0041] like Figure 1-Figure 8 As shown, the ultrasonic atomization device 100 includes a housing 10 and an atomization assembly 20, wherein the housing 10 defines an atomization chamber 11, and the atomization chamber 11 has a water inlet 12 and an atomization outlet 13. That is, the fluid flows into the atomization chamber 11 from the water inlet 12, is atomized by the atomization assembly 20, and then flows out from the atomization outlet 13.

[0042] Specifically, the atomizing assembly 20 is built into the atomizing chamber 11. The atomizing assembly 20 includes a supporting member 21 and an ultrasonic vibrating member 22. Figure 3 , Figure 8 , Figure 9-11 As shown, the support member 21 has a transverse partition 211, and the transverse partition 211 has a water passage 2111 penetrating through its thickness. The ultrasonic vibrator 22 is arranged on one side of the transverse partition 211 facing the atomization outlet 13 (such as Figure 3That is, when the ultrasonic atomization device 100 is working, the fluid will flow through the water outlet 2111 to one side of the transverse partition 211, and then form atomized droplets after being vibrated by the ultrasonic vibrator 22, and then sprayed out from the atomization outlet 13.

[0043] like Figure 3 , Figure 8 , Fig.13 and Fig.14 As shown, the ultrasonic vibrator 22 includes a first metal sheet 221 with micropores and a piezoelectric ceramic chip 222 integrated on the first metal sheet 221. The ultrasonic vibrator 22 and the electrode sheet 23 are arranged opposite to each other in the up and down directions, wherein the first metal sheet 221 faces the electrode sheet 23, the electrode sheet 23 is provided with a connecting port 231 connected to the water outlet 2111, and the piezoelectric ceramic chip 222 is provided with a through hole 2222 connected to the micropores, so that the fluid can pass through the connecting port 231 and the water outlet 211 to flow to the ultrasonic vibrator 22. When the ultrasonic vibrator 22 is started, the vibration wave generated by the piezoelectric ceramic chip 222 vibrates the fluid on the first metal sheet 221 to form fine droplets, and the fine droplets pass through the micropores on the first metal sheet 221 and the through hole 2222 on the piezoelectric ceramic chip 222 in turn, and finally send the droplets out of the atomization port.

[0044] The transverse partition 211 faces the other side of the water inlet 12 (such as Figure 3 The electrode sheet 23 is provided on the upper side of the electrode sheet 23. The structure of the electrode sheet 23 is as follows Fig.15 The first metal sheet 221 and the piezoelectric ceramic chip 222 form an atomization circuit, the first metal sheet 221 and the electrode sheet 23 form a water path detection circuit, one of the first metal sheet 221 and the electrode sheet 23 serves as a negative electrode, and the other serves as a positive electrode. The electrode sheet 23 and the piezoelectric ceramic chip 222 are both provided with a connecting hole corresponding to the water hole 2111.

[0045] When the ultrasonic atomization device 100 is working, when there is fluid passing through, the electrode sheet 23 and the first metal sheet 221 are connected, and the water path detection circuit forms a closed loop, and then the atomization circuit between the first metal sheet 221 and the piezoelectric ceramic chip 222 can be connected. In other words, before the ultrasonic vibrator 22 works, the flow path in the atomization chamber 11 is detected in advance to confirm whether there is fluid passing through the atomization chamber 11. Once no fluid is detected to flow through, the ultrasonic vibrator 22 can be stopped in time, or a water inlet demand can be issued to replenish water to the ultrasonic atomization device 100 in time. In this way, the problem of dry vibration of the ultrasonic vibrator 22 can be avoided and the service life of the ultrasonic atomization device 100 can be extended. Among them, the electrode sheet 23 can be serrated to improve the detection accuracy.

[0046] The water inlet 12 of the ultrasonic atomization device 100 is connected to a water tank. To avoid water accumulation in the water tank, which may breed bacteria and form odor, the ultrasonic atomization device 100 stops ultrasonic atomization when it can no longer detect fluid flowing through, that is, the ultrasonic atomization device stops working when the water in the water tank is completely consumed.

[0047] In short, according to the ultrasonic atomization device 100 for clothing processing equipment of the embodiment of the present invention, the atomization component 20 has the functions of water path detection and vibration atomization, can accurately control the start and stop points of the ultrasonic vibration part, avoids the dry vibration problem of the ultrasonic atomization device 100, and improves the service life and wrinkle removal ability of the ultrasonic atomization device 100.

[0048] In some embodiments of the present invention, Figure 1-Figure 8 As shown, the housing 10 has an upper cover 14 and a lower cover 15 that are connected to each other, and the upper cover 14 and the lower cover 15 together form an atomization chamber 11. Figure 3 and Figure 8 As shown, the upper cover 14 is provided with a water inlet 12, the lower cover 15 is provided with an atomization outlet 13, and the atomization assembly 20 is built into the atomization chamber 11 and is located in the lower cover 15. In this way, during assembly, the atomization assembly 20 can be assembled in the lower cover 15 first, and then the upper cover 14 is covered on the upper cover 14, so that the atomization assembly 20 is confined in the atomization chamber 11.

[0049] In order to improve the sealing between the upper cover 14 and the lower cover 15 and prevent water seepage during use of the ultrasonic atomization device 100, the upper cover 14 and the lower cover 15 can be connected by ultrasonic welding.

[0050] In an optional embodiment, the upper cover 14 includes a cover plate 141 and a clamping plate 142 forming the bottom of the cover plate 141, and the lower cover 15 is provided with a clamping groove 151 that cooperates with the clamping plate 142. That is, the upper end surface of the lower cover 15 is closed by the cover plate 141, and the sealing and connection strength between the upper cover 14 and the lower cover 15 are improved by the cooperation of the clamping plate 142 and the clamping groove 151, so that the upper cover 14 and the lower cover 15 form a structurally stable whole, thereby improving the service life of the ultrasonic atomization device 100.

[0051] In a further optional embodiment, the ultrasonic atomization device 100 further includes a guide member 30. The guide member 30 extends into and is clamped in the atomization chamber 11, and the guide member 30 introduces the fluid into the atomization chamber 11 and prevents bubbles from forming on the water path from the water inlet 12 to the atomization outlet 13 to block the normal flow of the fluid.

[0052] That is, when the water inlet pipe 16 is connected to the water source, at least part of the fluid can flow into the atomizing chamber 11 along the guide member 30. In this way, the impact force of the fluid flowing to the atomizing chamber 11 can be reduced, and bubbles can be avoided during the flow of the fluid, which makes the fluid unable to flow normally. It should be noted that the guide member 30 reduces the formation of bubbles to a certain extent, but does not completely prevent the formation of bubbles. It can be understood that the formation of some small bubbles is not enough to affect the normal flow of the fluid.

[0053] In a further optional example, the thickness of the guide member 30 is between 0.02 mm and 2 mm. For example, the thickness of the guide member 30 can be 0.02 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 1 mm, 1.5 mm or 2 mm. It is understood that when the fluid flows through the thin guide member 30, the formation conditions of bubbles can be destroyed, that is, the guide member 30 can cut the fluid to avoid the generation of bubbles. The guide member 30 can be a plastic part or a metal part.

[0054] Furthermore, if Figure 3 , Figure 8 and Fig.12 As shown, the flow guide 30 is provided with a diverter groove 33 extending along its length direction. The diverter groove 33 is located in the middle of the flow guide 30. The diverter groove 33 can further destroy the formation conditions of bubbles and ensure that the fluid in the atomization chamber 11 flows normally and stably.

[0055] In a further optional example, the flow guide 30 extends into the water passage 2111 , that is, the flow guide 30 guides the fluid to a position close to the ultrasonic vibration part 21 as much as possible, thereby providing sufficient fluid for the atomization of the ultrasonic vibration part 21 .

[0056] In further optional examples, such as Figure 3 , Figure 8 and Fig.12 As shown, a first limiting portion 31 is provided at one end of the guide member 30, and a second limiting portion 32 is provided at the other end of the guide member 30. The first limiting portion 31 abuts against the outer end surface of the water inlet pipe 16, and the second limiting portion 32 abuts against the inner end surface of the water inlet pipe 16. That is, the guide member 30 is fixed between the outer end surface and the inner end surface of the water inlet pipe 16 by the first limiting portion 31 and the second limiting portion 32. The guide member 30 can be a flexible plastic part or a metal sheet, thereby improving the flexibility of the guide member 30 and making it more convenient to assemble the guide member 30 on the water inlet pipe 16. Preferably, the guide member 30 is made of a safe, non-toxic, high temperature resistant and highly flexible material. Furthermore, the surface of the guide member 30 is smooth, so that bubbles are less likely to adhere.

[0057] In a specific embodiment of the present invention, Figure 3 , Figure 8 and Fig.12 As shown, both ends of the flow guide 30 have arc-shaped portions, so that when the fluid flows through the flow guide 30, it is not easy to produce a sudden change in the fluid boundary, thereby ensuring smooth flow of the fluid and further reducing the generation of bubbles.

[0058] It is understandable that the ultrasonic atomization device 100 is mounted on a clothing processing device, and fiber debris dropped from the clothing may clog the atomization outlet 13. To solve the above problem, Figure 5-Figure 7 As shown, the ultrasonic atomization device 100 also includes: a vent pipe 17, and the outlet of at least one vent pipe 17 is connected to the atomization outlet 13. That is, the vent pipe 17 can be one or more, and the multiple vent pipes 17 can be distributed on the housing 10 of the ultrasonic atomization device 100, or can be distributed on other surfaces. In this way, when the clothing processing equipment is in the drying stage, air is blown to the atomization outlet 13 through the vent pipe 17 to avoid the atomization outlet 13 from forming a return air area and accumulating debris, thereby ensuring the smoothness of the atomization chamber 11. Among them, the assembly position of the ultrasonic atomization device 100 can be on the cylinder body, window pad or door body of the clothing processing equipment.

[0059] In a further optional embodiment, Figure 3 Combination Figure 4 ,like Figure 7 Combination Figure 8 The atomization outlet 13 is a gradually expanding outlet. The gradually expanding outlet can fully disperse the atomized droplets and improve the wrinkle removal ability of the ultrasonic atomization device 100.

[0060] In some embodiments of the present invention, Figure 3 and Figure 8 As shown, a rubber pad 24 is provided between the electrode sheet 23 and the upper cover 14, and / or between the transverse partition 211 and the ultrasonic vibrator 22, and / or between the ultrasonic vibrator 22 and the lower cover 15. That is, a plurality of rubber pads 24 are used to prevent the water in the atomization chamber 11 from leaking outward, thereby improving the sealing performance of the ultrasonic atomization device 100, and arranging a plurality of rubber pads 24 in the longitudinal direction of the ultrasonic atomization device 100 can play a buffering role, thereby improving the vibration resistance of the ultrasonic atomization device 100.

[0061] In other embodiments of the present invention, Fig.13 and Fig.14 As shown, a first metal sheet 221 is provided on one side of the piezoelectric ceramic chip 222, and a second metal sheet 221 is provided on the other side of the piezoelectric ceramic chip 222, that is, the ultrasonic vibrator 22 is a "sandwich" sandwich structure, and the piezoelectric ceramic chip 222 is sandwiched between the first metal sheet 221 and the second metal sheet 223. In this way, the wiring terminals 25 of the external circuit can be welded on the first metal sheet 221 and the second metal sheet 223, thereby improving the reliability of the welding of the wiring terminals 25 and preventing the wiring terminals 25 from falling off during use.

[0062] The clothing processing apparatus according to an embodiment of the present invention includes the ultrasonic atomization device 100 of the above-mentioned embodiment. Since the ultrasonic atomization device 100 according to the embodiment of the present invention has a long service life and good wrinkle removal ability, the clothing processing apparatus according to the embodiment of the present invention has better wrinkle removal ability for clothing and low maintenance frequency.
