DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 6 As shown, an embodiment of the present invention provides a bidirectional reflection type ultrasonic atomization transducer, including an ultrasonic emitting device and an ultrasonic reflecting device.

[0028] The ultrasonic emitting device includes a piezoelectric ceramic sheet 1, and electrodes (not shown) are provided on the left and right sides of the piezoelectric ceramic sheet 1. That is, when the piezoelectric ceramic sheet 1 is vertically immersed in liquid, the left and right sides of the piezoelectric ceramic sheet 1 can emit ultrasonic waves in the liquid in the left and right directions respectively.

[0029] The ultrasonic reflection device comprises a reflection member 2 , the reflection member 2 is provided with a reflection surface 201 , and the left and right side surfaces of the piezoelectric ceramic sheet 1 correspond to the reflection surface 201 respectively.

[0030] When in use, the piezoelectric ceramic piece 1 is placed vertically into the liquid in the water storage container 7, and the reflector 2 is placed into the liquid in the water storage container 7. The reflector 2 can then reflect the ultrasonic waves emitted in two directions from the left and right sides of the piezoelectric ceramic piece 1 upwards respectively, and then reflect the ultrasonic waves off the liquid surface to achieve atomization.

[0031] Therefore, the bidirectional reflection ultrasonic atomization transducer described in the embodiment of the present invention achieves the effect that a single piezoelectric ceramic sheet 1 simultaneously generates two left and right ultrasonic atomization paths, thereby greatly improving the ultrasonic atomization efficiency.

[0032] Compared with a traditional ultrasonic atomization transducer in which a single piezoelectric ceramic piece can only generate a single ultrasonic atomization path, the bidirectional reflection ultrasonic atomization transducer described in the embodiment of the present invention can improve the atomization efficiency by nearly 1 times and has a better atomization effect.

[0033] In a specific embodiment of the present invention, the angle between the ultrasonic wave emitted by the piezoelectric ceramic sheet 1 and the ultrasonic wave reflected by the reflector 2 is set to θ, and the angle θ can be a right angle, an acute angle, or an obtuse angle. That is, the angle θ can be arbitrarily set according to actual use requirements.

[0034] Among them, when the angle between the ultrasonic wave emitted by the piezoelectric ceramic piece 1 and the ultrasonic wave reflected by the reflector 2 is set to an acute angle or an obtuse angle, since the ultrasonic wave is inclined to the liquid surface, the liquid level depth and the fogging height required for the bidirectional reflection ultrasonic atomization transducer to atomize can be reduced.

[0035] Specifically, the range of the angle θ can be set to 20°~80° or 100°~170°. At this time, the bidirectional reflection ultrasonic atomization transducer can ensure a good atomization effect while requiring a lower liquid level depth and atomization height, making it more convenient to use.

[0036] In a further embodiment of the present invention, two reflective members 2 may be provided, and the two reflective members 2 are symmetrically arranged on the left and right sides of the piezoelectric ceramic sheet 1 .

[0037] like Figures 1 to 3 As shown, in a specific embodiment, the two reflective elements 2 are respectively reflective blocks, that is, the two reflective blocks are symmetrically arranged on the left and right sides of the piezoelectric ceramic sheet 1 .

[0038] Each reflection block is provided with a reflection surface 201 on the side facing the piezoelectric ceramic sheet 1, and the reflection surface 201 is fan-shaped and is a concave spherical surface. Each reflection surface 201 extends downwardly at an angle from one end away from the piezoelectric ceramic sheet 1 to the other end close to the piezoelectric ceramic sheet 1, and the width of the reflection surface 201 gradually decreases from top to bottom, so that the ultrasonic wave emitted from the piezoelectric ceramic sheet 1 can fall on the reflection surface 201 of the reflection block and can be reflected by the reflection surface 201.

[0039] Since the reflection surface 201 on the reflection block is a concave spherical surface, the ultrasonic wave reflected by the reflection surface 201 of the same reflection block can produce a focusing effect. When the angle θ between the ultrasonic wave emitted by the piezoelectric ceramic sheet 1 and the ultrasonic wave reflected by the reflection block is set to an acute angle, the ultrasonic wave reflected by the two reflection blocks can produce a focusing effect. That is, when the ultrasonic wave emitted by the piezoelectric ceramic sheet 1 is reflected by the two reflection blocks, a double focusing effect can be produced, thereby greatly improving the atomization efficiency of the bidirectional reflection type ultrasonic atomization transducer.

[0040] Specifically, the ultrasonic reflection device further includes a reflection block mounting seat 3 , and the reflection block is mounted and fixed by the reflection block mounting seat 3 .

[0041] Specifically, the ultrasonic transmitting device further includes a ceramic piece mounting seat 4 , and the piezoelectric ceramic piece 1 is mounted and fixed by the ceramic piece mounting seat 4 .

[0042] Specifically, the reflector block mounting seat 3 is provided with a first mounting groove 301 with an upper opening, and a support leg 302 is provided at the bottom of the reflector block mounting seat 3. The ceramic plate mounting seat 4 and the two reflector blocks are both arranged in the first mounting groove 301. The ceramic plate mounting seat 4 is arranged in the middle of the first mounting groove 301, and the two reflector blocks are symmetrically arranged on the left and right sides of the ceramic plate mounting seat 4.

[0043] The ceramic plate mounting seat 4 and the reflector block mounting seat 3 can be an integrated structure or a split structure. When the ceramic plate mounting seat 4 and the reflector block mounting seat 3 are split structures, the ceramic plate mounting seat 4 is detachably mounted in the first mounting groove 301 .

[0044] Specifically, the ceramic piece mounting seat 4 is provided with a second mounting groove 401 with an opening at the upper end, and the piezoelectric ceramic piece 1 is vertically mounted in the second mounting groove 401. Through holes 402 are respectively provided on the side walls of the second mounting groove 401 corresponding to the left and right sides of the piezoelectric ceramic piece 1, so that the ultrasonic waves emitted from the left and right sides of the piezoelectric ceramic piece 1 can pass through the two through holes 402 and project to the corresponding two reflection blocks.

[0045] Specifically, the ultrasonic transmitting device further includes a sealing ring 5 , which is sleeved on the outer ring of the piezoelectric ceramic piece 1 . The piezoelectric ceramic piece 1 can be installed in the second installation groove 401 through the sealing ring 5 , thereby fixing the piezoelectric ceramic piece 1 in the second installation groove 401 .

[0046] Specifically, when in use, the reflector block mounting seat 3 and the ceramic plate mounting seat 4 can be directly placed in the water storage container 7, so that the support feet 302 of the reflector block mounting seat 3 are in contact with the bottom surface of the water storage container 7, and then the two reflector blocks and the piezoelectric ceramic plate 1 are respectively arranged inside the water storage container 7 and immersed in the liquid.

[0047] like Figure 4 As shown, in another specific embodiment, the two reflective members 2 are respectively reflective plates, that is, the two reflective plates are symmetrically arranged on the left and right sides of the piezoelectric ceramic sheet 1 .

[0048] Each reflector is provided with a reflective surface 201 on the side facing the piezoelectric ceramic sheet 1, and the reflective surface 201 is flat. Each reflective surface 201 is arranged to be inclined downward from the side away from the piezoelectric ceramic sheet 1 to the other side close to the piezoelectric ceramic sheet 1. Thus, the ultrasonic wave emitted from the piezoelectric ceramic sheet 1 can fall on the reflective surface 201 of the reflector and can be reflected by the reflective surface 201.

[0049] When the angle θ between the ultrasonic wave emitted by the piezoelectric ceramic plate 1 and the ultrasonic wave reflected by the reflector is set to an acute angle, the ultrasonic wave reflected by the two reflectors can produce a focusing effect, thereby further improving the atomization efficiency of the bidirectional reflection type ultrasonic atomization transducer.

[0050] Specifically, when in use, the two reflective plates can be directly connected to the bottom surface of the water storage container 7, or the two reflective plates can be connected to the bottom surface of the water storage container 7 through a mounting bracket. Similarly, the piezoelectric ceramic sheet 1 can be directly connected to the bottom surface of the water storage container 7, or the piezoelectric ceramic sheet 1 can be connected to the bottom surface of the water storage container 7 through a mounting bracket, so that the two reflective plates and the piezoelectric ceramic sheet 1 can be fixed inside the water storage container 7 respectively and immersed in the liquid.

[0051] like Figure 5 As shown, in another specific embodiment, the reflector 2 is provided with one, and a reflective surface 201 is provided on the upper end surface of the reflector 2, and the reflective surface 201 is an arc surface.

[0052] The piezoelectric ceramic piece 1 is arranged at the center of the reflecting surface 201, and the extension direction of the piezoelectric ceramic piece 1 passes through the center of the arc surface. That is, the reflecting surface 201 is an axisymmetric structure. When in use, the piezoelectric ceramic piece 1 is arranged vertically at the center of the reflecting surface 201, and ensures that the ultrasonic waves emitted from the left and right sides of the piezoelectric ceramic piece 1 can be reflected upward by the reflecting surface 201.

[0053] When the angle θ between the ultrasonic wave emitted by the piezoelectric ceramic piece 1 and the ultrasonic wave reflected by the arc surface is set to an acute angle, the ultrasonic wave emitted by the left and right sides of the piezoelectric ceramic piece 1 can produce a focusing effect when reflected by the arc surface, thereby further improving the atomization efficiency of the bidirectional reflection ultrasonic atomization transducer.

[0054] like Figure 6 As shown, in another specific embodiment, the reflector 2 is provided with a reflective surface 201 which is a spherical crown surface.

[0055] The piezoelectric ceramic sheet 1 is disposed at the center of the reflective surface 201, and the extension direction of the piezoelectric ceramic sheet 1 passes through the center of the spherical crown surface. Figure 6 In the use state shown, the piezoelectric ceramic piece 1 is vertically arranged at the center of the reflective surface 201. This structural form enables the ultrasonic waves emitted from the left and right sides of the piezoelectric ceramic piece 1 to be always reflected upward by the spherical crown surface when the piezoelectric ceramic piece 1 rotates arbitrarily along the vertical axis in the reflective surface 201.

[0056] Since the reflecting surface 201 is a spherical crown surface, the ultrasonic wave emitted from the same side of the piezoelectric ceramic piece 1 can produce a focusing effect when it is reflected by the spherical crown surface. When the angle θ between the ultrasonic wave emitted by the piezoelectric ceramic piece 1 and the ultrasonic wave reflected by the spherical crown surface is set to an acute angle, the ultrasonic wave emitted from the left and right sides of the piezoelectric ceramic piece 1 can produce a focusing effect when it is reflected by the spherical crown surface. That is, when the ultrasonic wave emitted by the piezoelectric ceramic piece 1 is reflected by the spherical crown surface, a double focusing effect can be produced, thereby greatly improving the atomization efficiency of the bidirectional reflection type ultrasonic atomization transducer.

[0057] In a further embodiment of the present invention, the ultrasonic emitting device further comprises two leads 6, which are respectively connected to two electrodes of the piezoelectric ceramic sheet 1. When in use, the two leads 6 are respectively connected to a power source, so that the left and right sides of the piezoelectric ceramic sheet 1 can emit ultrasonic waves respectively.

[0058] Further, if Figure 1 and Figure 4As shown, when the liquid depth h2 in the water storage container 7 is set to be approximately equal to the focal length of the piezoelectric ceramic piece 1, the best atomization effect can be obtained. When the distance from the ultrasonic wave from the piezoelectric ceramic piece 1 to the reflecting surface 201 is set to L1, the distance from the ultrasonic wave from the reflecting surface 201 to the fogging area 8 is set to L2, and the distance from the liquid surface to the fogging area 8 is set to h1, then when L1+L2 is approximately equal to the focal length of the piezoelectric ceramic piece 1, the best atomization effect can be obtained.

[0059] Therefore, compared with the traditional atomization method of directly placing the piezoelectric ceramic sheet 1 horizontally in the liquid, under the same conditions (the focal length of the piezoelectric ceramic sheet 1 is the same), the bidirectional reflection ultrasonic atomization transducer described in the embodiment of the present invention is used for atomization operation, which can effectively reduce the required liquid depth h2.

[0060] The angle between L1 and L2 is set to θ. If the height of the reflective surface 201 itself is not considered, L2 should be greater than or equal to h2 (where θ is equal to 90°, L2 is equal to h2). Therefore, by adjusting the distance between the piezoelectric ceramic sheet 1 and the reflective surface 201, that is, by adjusting the distance L1, the required liquid depth h2 can be adjusted. The larger L1 is, the smaller the required liquid depth h2 is, thereby achieving low liquid level atomization.

[0061] In addition, by adjusting the angle θ, the required liquid depth h2 can also be adjusted. When θ is less than 90°, the two ultrasonic waves emitted from the left and right sides of the piezoelectric ceramic sheet 1 can be focused at one point after being reflected by the reflecting surface 201, thereby achieving an acoustic focusing effect, which can further improve the atomization efficiency.

[0062] To sum up, the bidirectional reflection ultrasonic atomization transducer described in the embodiment of the present invention, by respectively arranging electrodes on the left and right sides of the piezoelectric ceramic sheet, enables the piezoelectric ceramic sheet to emit ultrasonic waves in the liquid in the left and right directions respectively. At the same time, by arranging a reflecting surface on the reflecting element, the left and right sides of the piezoelectric ceramic sheet correspond to the reflecting surface respectively, so that the ultrasonic waves emitted by the piezoelectric ceramic sheet in two directions can be reflected respectively by the reflecting element, so that the ultrasonic waves are reflected off the liquid surface to achieve atomization, thereby greatly improving the ultrasonic atomization efficiency.
