Description

Technical Field

[0001] The utility model relates to a loudspeaker waterproof mechanism for a cooking machine. Background Art

[0002] In recent years, many cooking robots have been launched on the market, bringing great convenience to restaurants. When debugging and working, cooking robots need to remind operators of reservations and broadcast announcements, so speakers are needed. However, since robots need to be washed frequently, it is important to consider the waterproofness of the speakers to ensure that the equipment does not have speaker failures.

[0003] In the prior art, the waterproof structure of the speaker has various characteristics. Generally, the structure of the speaker itself is improved, mainly using sealing and other measures. For example, the Chinese patent with publication number CN208227317U discloses a new waterproof speaker, including an outer shell, a waterproof breathable membrane and a card slot. The waterproof breathable membrane is installed on the outside of the groove. The core of this solution is that a waterproof breathable membrane with a detachable installation structure is provided on the outside of the speaker body. The waterproof breathable membrane is provided to prevent water from entering the speaker body and causing damage to it, while not hindering the sound from coming out. This solution requires the speaker itself to be modified, which is costly and cannot use a general speaker.

[0004] Therefore, it is necessary to design a new waterproof mechanism for the loudspeaker. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a loudspeaker waterproof mechanism for a cooking machine. The loudspeaker waterproof mechanism for a cooking machine has a simple and ingenious structure and is easy to implement.

[0006] The technical solution of the utility model is as follows:

[0007] A speaker waterproof mechanism for a cooking machine, comprising a speaker and a mounting base for mounting the speaker; the speaker is fixed on a back plate of the mounting base;

[0008] After the speaker waterproof mechanism is installed on the cooking machine, the sound-emitting surface of the speaker is oriented obliquely downward, and the angle between the axis of the speaker and the horizontal plane is α, 0<α<90°;

[0009] The front end surface of the mounting seat is provided with a sound transmission panel with a plurality of sound transmission holes.

[0010] The cross section of the mounting seat is a parallelogram or a trapezoid. It may not be a parallelogram, such as a common quadrilateral. Or it may be other shapes, such as a hexagon.

[0011] The loudspeaker is fixed to the outer side of the back plate of the mounting base, and can also be installed on the upper side of the back plate (i.e., the upper side plate).

[0012] The cross section of the mounting seat is a right-angle trapezoid.

[0013] After the waterproof mechanism of the loudspeaker is installed on the cooking machine, the sound transmission panel is located in a vertical plane.

[0014] There are 2 speakers, which are arranged side by side.

[0015] The back plate is provided with a plurality of mounting holes, and the speaker is mounted on the back plate by means of bolts and welding nuts 504 .

[0016] α is 30°, 45° or 60°.

[0017] Beneficial effects:

[0018] The utility model discloses a speaker waterproof mechanism for a cooking machine, which mainly comprises a speaker sound transmission panel, a speaker mounting plate, a speaker, a sealing pad, etc. The speaker is separated from the speaker sound transmission panel by an inverted mounting base, and even if part of the water flows into the speaker mounting base, it will flow out to the bottom of the speaker mounting plate through the holes on the speaker sound transmission plate due to the water's own gravity, thereby protecting the speaker and preventing water from entering the speaker. The structure is simple, easy to install, low in production cost, and high in efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0029] Example 1: Figure 1-7 As shown, a speaker waterproof mechanism for a cooking machine includes a speaker 503 and a mounting base 502 for mounting the speaker; the speaker is fixed on a back plate 5021 of the mounting base;

[0030] Specifically, the mounting seat includes a back plate, two side plates and two end plates; the cross section of the mounting seat is a right-angle trapezoid.

[0031] After the waterproof mechanism of the speaker is installed on the cooking machine, the sound-emitting surface of the speaker is oriented obliquely downward, and the angle between the axis of the speaker and the horizontal plane is α, which is 30°.

[0032] The front end surface of the mounting base is provided with a sound transmission panel 501 with a plurality of sound transmission holes.

[0033] The speaker is fixed to the outside of the back plate 5021 of the mounting base, so that a cavity is formed inside the mounting base, which has a better sound effect.

[0034] After the waterproof mechanism of the loudspeaker is installed on the cooking machine, the sound transmission panel is located in a vertical plane.

[0035] There are 2 speakers, which are arranged side by side.

[0036] The back plate is provided with a plurality of mounting holes, and the loudspeaker is mounted on the back plate by means of bolts and welding nuts 504. The welding nuts 504 (or ordinary nuts) are arranged on the inner side of the through holes (mounting holes) of the back plate 5021 of the mounting seat.
