[0017] In the following description, the direction in which the central axis Ax of the horn body 11B extends is referred to as the "axial direction Z". In addition, for the sake of convenience, in the axial direction Z, the front end side of the horn body 11B viewed from the main body 10 is referred to as the "front end side in the axial direction Z", and the opposite side is referred to as the "bottom side in the axial direction Z". In addition, the direction orthogonal to the axial direction Z is referred to as the "radial direction X". In addition, in a plan view viewed from the axial direction Z (hereinafter, referred to only as the plan view), the direction surrounding the central axis Ax is referred to as the "circumferential direction Y".
[0018] Figure 6 FIG. 1 is an appearance diagram of the speaker body 11B. Figure 6 As shown in FIG. 1 , the front end portion 11D of the speaker body 11B is a flat rectangle having long sides and short sides in a plan view. In the following description, the direction along the long sides of the speaker body 11B in the radial direction X is referred to as “long side direction X1”. In addition, the direction along the short sides of the speaker body 11B in the radial direction X is referred to as “short side direction X2”.
[0019] The bottom side of the horn body 11B in the axial direction Z has a circular cross-section. The horn body 11B is configured such that the cross-section gradually becomes a flattened rectangular shape from the base portion 11C toward the front end portion 11D.
[0020] The base 11C of the horn body 11B includes a housing portion 11E, a flange portion 11F, and a connecting portion 11G. The housing portion 11E, the flange portion 11F, and the connecting portion 11G are integrally formed of a metal material together with the front end portion 11D.

Figure 7 and Figure 8 As shown, the horn cover 12 is a member that covers the entire circumference of the ultrasonic horn 11 from the outside in the radial direction X. The horn cover 12 is disposed coaxially with the ultrasonic horn 11 .
[0025] The speaker cover 12 has a cylindrical shape having a top portion. The speaker cover 12 has an opening 12A. The opening 12A is arranged at the center of the top portion of the speaker cover 12.
[0026] like Figure 8 As shown, the horn cover 12 includes a first tube 12B, a second tube 12C, a first top 12D, and a second top 12E. The first tube 12B, the second tube 12C, the first top 12D, and the second top 12E are integrally formed of a synthetic resin material and are coaxially arranged with each other.
[0027] The first barrel 12B and the second barrel 12C are in a cylindrical shape. The outer diameter and inner diameter of the first barrel 12B are smaller than the outer diameter and inner diameter of the second barrel 12C. The front end side of the axial direction Z of the first barrel 12B protrudes toward the front end side of the axial direction Z than the end of the front end side of the axial direction Z in the second barrel 12C. The bottom side of the axial direction Z of the first barrel 12B overlaps with the second barrel 12C in the radial direction X.
[0028] The first top portion 12D is connected to the end edge of the front end side of the first tube portion 12B in the axial direction Z. The first top portion 12D closes the opening of the front end side of the first tube portion 12B in the axial direction Z. An opening portion 12A is arranged in the central portion of the first top portion 12D. The opening portion 12A is in a rectangular shape that is long in the long side direction X1 and small in the short side direction X2 when viewed from above.
[0029] The inner peripheral surface of the second cylindrical portion 12C is formed with an internal thread portion 12G (see Fig.12 ).
[0030] The second top portion 12E has an annular shape connecting the first cylindrical portion 12B and the second cylindrical portion 12C in the radial direction X. Specifically, the second top portion 12E is arranged between portions overlapping each other in the radial direction X between the outer peripheral surface of the first cylindrical portion 12B and the inner peripheral surface of the second cylindrical portion 12C.
[0031] The second top portion 12E has a through hole 12F. When viewed from above, the through hole 12F is arranged outside the opening 12A in the longitudinal direction X1. A pair of through holes 12F are arranged in the second top portion 12E at positions sandwiching the opening 12A along the longitudinal direction X1. The through hole 12F penetrates the horn cover 12 in the axial direction Z.
[0032] (1-4) Structure of the speaker cover 13 like Figure 7 As shown, the horn cover 13 is a cylindrical member. The horn cover 13 is attached to the front end side of the horn housing 12 in the axial direction Z. The horn cover 13 is formed of a synthetic resin material having light transmittance.
[0033] The horn cover 13 is open on both sides in the axial direction Z. The horn cover 13 has a rectangular shape with rounded corners when viewed from above. The horn cover 13 is arranged coaxially with the ultrasonic horn 11 .
[0034] The horn cover 13 extends along the outer shape of the horn body 11B in the axial direction Z. The horn cover 13 has a tapered shape with the outer diameter and the inner diameter gradually decreasing toward the front end side in the axial direction Z. Figure 5 As shown, the inner peripheral surface of the horn cover 13 is spaced apart from the outer surface of the horn body 11B so as not to contact the horn body 11B.
[0035] The ultrasonic cleaner 1 further includes a bracket 14 and a water-stopping gasket 15 .
[0036] (1-5) Structure of the bracket 14 like Figure 5 and Figure 8 As shown, the bracket 14 has a cylindrical shape that covers the entire circumference of the housing portion 11E and the flange portion 11F of the ultrasonic horn 11 from the outside in the radial direction X. The bracket 14 fixes the ultrasonic horn 11 to the horn cover 12. The bracket 14 is disposed coaxially with the ultrasonic horn 11.
[0037] like Figure 7 As shown, the bracket 14 includes a fixed cylindrical portion 14A, a holding portion 14B, and an installation portion 14C. The fixed cylindrical portion 14A, the holding portion 14B, and the installation portion 14C are integrally formed of a synthetic resin material and are coaxially arranged with each other.
[0038] The fixed cylinder 14A is an octagonal cylinder when viewed from above. A pair of retaining portions 14B are arranged outside the fixed cylinder 14A in the long side direction X1. The retaining portion 14B is in the shape of a plate extending in the axial direction Z. The retaining portion 14B protrudes further to both sides of the axial direction Z than the fixed cylinder 14A. The mounting portion 14C is provided on the outer peripheral surface of the fixed cylinder 14A. The fastening bolt B is inserted into the mounting portion 14C.
[0039] (1-6) Structure of Water Stop Gasket 15 like Figure 5 and Figure 7 As shown, the waterproof washer 15 is in an annular shape with both end surfaces in the axial direction Z being flat. The waterproof washer 15 ensures waterproofing between the inside and the outside of the main body 10 . The waterproof washer 15 is disposed coaxially with the ultrasonic horn 11 .
[0040] Fig.9A and Fig. 9B It is a diagram showing the structure of the waterproof gasket 15. Fig.9A This is an external view of the waterproof washer 15 as viewed from the front end side in the axial direction Z. Fig. 9B It is a front view of the water stop washer 15.
[0041] like Fig.9A and Fig. 9B As shown, the water stop gasket 15 includes a gasket body 15A and an extension 15B. The gasket body 15A is annular. The thickness of the gasket body 15A in the axial direction Z is constant over the entire area. The outer shape of the gasket body 15A is along the shape of the flange 11F of the speaker body 11B when viewed from above. A through hole is formed on the gasket body 15A for the speaker body 11B to be inserted. The through hole is circular when viewed from above.
[0042] The extension portion 15B extends outward in the longitudinal direction X1 from the outer end portion of the gasket body 15A in the longitudinal direction X1. The length of the extension portion 15B in the transverse direction X2 is formed to be greater than the length in the longitudinal direction X1.
[0043] (1-7) Installation structure of each component Fig.10 yes Figure 5 An enlarged view of the main parts of the ultrasonic cleaner 1 is shown. Fig.11 yes Figure 4 An enlarged view of the main part of the cross section taken along line XI-XI is shown. Fig.12 yes Figure 4 An enlarged view of the main part of the cross section taken along line XII-XII is shown.
[0044] like Figure 10 to Figure 12 As shown, the front end portion 11D of the speaker body 11B is inserted through the opening 12A of the speaker cover 12 and protrudes toward the outside. The speaker body 11B is covered in the entire area in the circumferential direction Y by the speaker cover 12 and the speaker cover 13 .
[0045] The bracket 14 is disposed between the speaker cover 12 and a portion of the base 11C of the speaker body 11B in the radial direction X. Fig.12 As shown, the bracket 14 is fixed to the speaker cover 12 by the fastening bolts B inserted into the mounting portion 14C. Thus, the bracket 14 holds the base 11C of the speaker body 11B.
[0046] like Figure 10 to Figure 12 As shown, the flange 11F of the speaker body 11B is held by the end surface of the fixed cylinder 14A of the bracket 14 at the front end side in the axial direction Z. The speaker cover 12 and the bracket 14 sandwich the flange 11F of the base 11C of the speaker body 11B in the axial direction Z.
[0047] The lower edge of the speaker cover 13 is inserted between the first cylinder portion 12B and the second cylinder portion 12C. A fixing piece (not shown) formed at the lower edge of the speaker cover 13 may also be inserted into a through hole 12F formed at the second top portion 12E of the speaker cover 12. The through hole 12F is located outside the flange portion 11F of the speaker body 11B in the radial direction X.
[0048] like Fig.10 As shown, the water stop washer 15 is disposed on the front end side of the flange portion 11F in the axial direction Z. The water stop washer 15 is sandwiched between the flange portion 11F and the second top portion 12E of the bell housing 12 in the axial direction Z. Therefore, the water stop washer 15 can ensure water stopping between the bell housing 12 and the flange portion 11F.
[0049] The waterproof washer 15 is held by the end surface of the flange portion 11F on the front end side in the axial direction Z from the bottom side in the axial direction Z. The waterproof washer 15 is held by the holding portion 14B of the bracket 14 from the bottom side in the axial direction Z.
[0050] The extended portion 15B of the water-stopping gasket 15 overlaps with the through hole 12F of the bell housing 12 in the axial direction Z. That is, the outer end portion of the water-stopping gasket 15 in the longitudinal direction X1 extends outward in the longitudinal direction X1 and overlaps with the through hole 12F in the axial direction Z. Therefore, the water-stopping gasket 15 can effectively prevent water from entering through the through hole 12F of the bell housing 12.
[0051] Here, “overlapping in the axial direction” is not limited to the case where the extension portion 15B overlaps the entire area of the through hole 12F in the axial direction Z, but also includes the case where the extension portion 15B overlaps a portion of the through hole 12F in the axial direction Z.
[0052] (2) Structure of the drive circuit Next, a driving circuit of the ultrasonic cleaner 1 will be described.
[0053] like Figure 5 As shown, the ultrasonic cleaner 1 includes a battery BT, a main circuit board 30 , a transformer 31 , a drive unit 103 , an operation circuit board 32 , a push button switch 10C, and an operation circuit board 32 .
[0054] The battery BT is a rechargeable type. The battery BT and the main circuit board 30 are built into the body cover 10A. The driving unit 103 including the transformer 31 is mounted on the main circuit board 30. The operation circuit board 32 is arranged on the bottom side of the axial direction Z in the body cover 10A. The operation circuit board 32 is electrically connected to the push button switch 10C.
[0055] Fig.13 : is a circuit diagram showing a driving circuit of the ultrasonic cleaner 1. Fig.13 As shown, the ultrasonic cleaner 1 includes a DC / DC converter 101 , a control device 102 , a drive unit 103 , and an oscillation circuit 106 .
[0056] The positive terminal of the battery BT is connected to the input terminal of the DC / DC converter 101. The power supply terminal VDD of the control device 102 is connected to the output terminal of the DC / DC converter 101. The power supply terminal VCC of the control device 102 is connected to the negative terminal of the battery BT. In addition, the voltage input terminal VIN of the control device 102 is connected to the positive terminal of the battery BT.
[0057] Here, the DC / DC converter 101 converts, for example, 5.5V of the DC voltage of the battery BT into 3.3V of the DC voltage in accordance with the power supply voltage specification of the control device 102 .
[0058] A driving signal is output from the control device 102 to the driving unit 103. In addition, a signal from the switch unit 104 is input to the control device 102.
[0059] The driving unit 103 drives the ultrasonic vibrator 11A based on the driving signal from the control device 102. In the present embodiment, the frequency of the ultrasonic vibration is set to 38 kHz. The frequency of the ultrasonic vibration may be 30 kHz or more and 40 kHz or less, which is suitable for washing clothes.
[0060] (3) Operation of Ultrasonic Cleaner 1 Next, the driving state of the ultrasonic cleaner 1 is described. In the ultrasonic cleaner 1, the user presses the push button switch 10C. As a result, power is supplied from the battery BT, and the DC / DC converter 101, the control device 102, the drive unit 103, and the oscillation circuit 106 operate. Then, the ultrasonic vibrator 11A is driven by the drive unit 103 to vibrate. The ultrasonic horn 11 vibrates due to the vibration of the ultrasonic vibrator 11A.
[0061] Then, the tip of the horn portion 14a of the ultrasonic horn 11 is brought into contact with the clothes immersed in water as an example of a cleaning medium. Thus, the ultrasonic cleaner 1 removes dirt attached to the clothes by vibration.
[0062] At this time, the user sometimes makes the end edge along the long side of the front end 11D of the horn body 11B contact with the object to be cleaned and vibrates the ultrasonic horn 11. This is because, in the front end 11D, compared with the end edge along the short side, making the end edge along the long side contact is easier to increase the contact portion with the object to be cleaned, and can effectively clean.
[0063] Next, when the push button switch 10C is pressed, the ultrasonic horn 11 stops ultrasonic vibration and the power is turned off. As described above, the operation of the ultrasonic cleaner 1 is completed.
[0064] As described above, according to the ultrasonic cleaner 1 of the present embodiment, the bracket 14 and the horn cover 12 sandwich the flange portion 11F which is a part of the base portion 11C of the horn body 11B in the axial direction Z. Furthermore, the bracket 14 is fixed to the horn cover 12 and holds the base portion 11C. Therefore, the ultrasonic horn 11 can be firmly held by the bracket 14 and the horn cover 12, and the ultrasonic horn 11 can be supported with a simple structure.
[0065] In addition, the water-stopping gasket 15 is arranged only on one side of the axial direction Z (the front end side in the present embodiment) relative to the flange portion 11F. Moreover, by tightening the fastening bolts B, the flange portion 11F is pushed toward the horn cover 12 side, and the water-stopping gasket 15 is flattened and deformed in the Z direction. As a result, the horn cover 12 and the ultrasonic horn 11 are sealed. According to this configuration, compared with a structure in which the flange portion 11F is covered from both sides of the axial direction Z with a gasket, the water-stopping gasket 15 can be easily assembled to the flange portion 11F. As a result, the manufacturability of the ultrasonic cleaner 1 can be improved.
[0066] [Second embodiment] The ultrasonic cleaner 1 according to the second embodiment of the present invention is different in structure of a water stop washer 15 from that of the first embodiment.
[0067] (4) Structure of this embodiment Fig.14A It is a perspective view of a waterproof gasket 15 according to the second embodiment. Fig. 14B It is a plan view of the waterproof gasket 15 according to the second embodiment. Fig. 14C 2 is another perspective view of the water stop gasket 15 according to the second embodiment. Fig. 14C This is a perspective view when viewed from the bottom side in the axial direction Z of the waterproof gasket 15 .
[0068] like Figures 14A to 14C As shown, in the ultrasonic cleaner 1 , the extension portion 15B of the waterproof gasket 15 is formed thicker in the axial direction Z than the gasket main body 15A.
[0069] Fig.15FIG. 2 is an enlarged view of a main part of a longitudinal section of an ultrasonic cleaner 1 according to a second embodiment. Fig.15 As shown, in the ultrasonic cleaner 1, the protrusion 15B of the water stop washer 15 covers the flange 11F of the horn body 11B from the outer side in the longitudinal direction X1. Therefore, the flange 11F is held by the water stop washer 15 from both sides in the longitudinal direction X1.
[0070] As described above, in the ultrasonic cleaner 1 of the present embodiment, since the flange portion 11F can be held from both sides in the longitudinal direction X1 by the waterproof gasket 15 , the waterproof property by the waterproof gasket 15 can be ensured.
[0071] In addition, in the ultrasonic cleaning device 1, the end edge along the long side of the ultrasonic horn 11 contacts the object to be cleaned. Therefore, the vibration component of the ultrasonic vibrator 11A in the short side direction X2 orthogonal to the long side direction X1 becomes more effective. In addition, in the ultrasonic cleaning device 1, the waterproof gasket 15 does not cover the flange portion 11F from the outside in the short side direction X2.
[0072] Therefore, when the top end 11D is in contact with the object to be cleaned, the water-stopping gasket 15 can be used to suppress the obstruction of the vibration of the short-side direction X2 of the horn body 11B. In addition, in the long-side direction X1 orthogonal to the short-side direction X2, the water-stopping gaskets 15 on both sides of the horn body 11B are thicker than other parts. Therefore, the line of the long-side direction X1 passing through the center of the horn body 11B acts as a support axis of the horn body 11B, and the vibration of the short-side direction X2 can be stably transmitted to the front end 11D. That is, in the ultrasonic cleaner 1 involved in this embodiment, the vibration efficiency of the horn body 11B can be ensured, and the water-stopping property around the flange 11F can be ensured.
[0073] Above, with reference to the accompanying drawings ( Figure 1 to Figure 15 ) have described the embodiments of the present invention. However, the present invention is not limited to the above-mentioned embodiments, and can be implemented in various ways without departing from the scope of the main purpose. In addition, the multiple components disclosed in the above-mentioned embodiments can be appropriately changed. For example, a component of all the components shown in a certain embodiment can be added to the components of other embodiments, or some components of all the components shown in a certain embodiment can be deleted from the embodiment.
