Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "center", "length", "width", "thickness", "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", and the like, as used herein, refer to an orientation or positional relationship indicated in the drawings, which is used for convenience in describing the present invention and for simplicity in description, and does not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, is not to be construed as limiting the present invention.

An installation structure of an ultrasonic apparatus according to an embodiment of the present invention is described below with reference to fig. 1 to 18.

Referring to fig. 1 to 18, a mounting structure of an ultrasonic device according to an embodiment of the present invention may include: a base 10, an ultrasonic transducer device 20, and a sealing material 30.

Specifically, the inner side surface of the base 10 may be provided with a mounting recess 101, the mounting recess 101 is provided concavely, the ultrasonic vibrator device 20 may be protruded into the mounting recess 101 to be connected to the base 10, and the ultrasonic vibrator device 20 may have an ultrasonic wave emitting portion 21, the ultrasonic wave emitting portion 21 being located inside the base 10.

Thus, the ultrasonic waves generated by the operation of the ultrasonic transducer device 20 can be emitted to the outside through the ultrasonic emitting portion 21, and the ultrasonic waves act on the medium to form a complicated sound field, and a cavitation effect occurs at a place where the sound pressure difference is large, thereby performing ultrasonic treatment.

For example, when the mounting structure of the ultrasonic device is applied to cooking and heating equipment, the mechanical action and cavitation of ultrasonic waves can not only pretreat food materials when the food materials are not cooked, remove harmful substances such as dirt, pesticides and meat blood in the food materials, and are cleaner and safer, but also can promote the emulsification of the food materials and the extraction of nutrient substances in the cooking process, such as soup making process, porridge cooking process or other cooking processes with higher requirements on nutrition, reduce the extraction time of nutrient components in the food materials and the flavoring time of the food materials, make the soup more fragrant, make the taste of the food materials better, and also can perform ultrasonic cleaning on the cooking and heating equipment after the cooking is finished, so that scales attached to the cavity wall of the cooking cavity are dispersed, loosened and fallen off, thereby realizing the self-cleaning of the cooking and heating equipment, and the cleaning is easier and cleaner.

In addition, in the present invention, the ultrasonic vibrator device 20 is detachably connected to the base 10, so that the ultrasonic vibrator device 20 can be mounted on the base 10 when ultrasonic treatment is required, and the ultrasonic vibrator device 20 can be separated from the base 10 when equipment having a mounting structure of the ultrasonic vibrator device is required to be cleaned, so that cleaning is more convenient, the risk of water short circuit of the ultrasonic vibrator device 20 is reduced, and the connection gap between the ultrasonic vibrator device 20 and the base 10 is cleaned more cleanly, thereby preventing dirt from accumulating.

Alternatively, in some embodiments, the ultrasonic transducer device 20 may be formed as a handheld ultrasonic transducer device after being detached from the base 10, and may be applied to other equipment or working environments, so as to work without a single product, thereby greatly improving the applicability of the ultrasonic transducer device 20.

In addition, when the ultrasonic transducer device 20 is separated from the base 10, the notch of the mounting recess 101 is opened, and the surface of the base 10 is uneven, which is not good in appearance and has poor structural strength. Further, in the embodiment in which the installation recess 101 communicates the cooking cavity with the outside, the recess of the installation recess 101 is opened to make the cooking cavity not airtight, which affects the normal operation of the cooking heating apparatus. For example, the liquid food material in the cooking cavity may overflow from the mounting recess 101, and for example, in an embodiment in which the apparatus having the mounting structure of the ultrasonic device needs to operate under positive pressure or negative pressure, the recess of the mounting recess 101 is opened so that the apparatus cannot be pressurized or depressurized, and the apparatus having the mounting structure of the ultrasonic device cannot operate normally.

In the present invention, the blocking member 30 may be detachably connected to the base 10, and after the ultrasonic transducer device 20 is separated from the base 10, the recess of the mounting recess 101 may be blocked by the blocking member 30, so that not only the structure of the base 10 may be more beautiful, but also the apparatus having the mounting structure of the ultrasonic device may be normally operated. For example, when the apparatus having the ultrasonic device mounting structure is a pressure cooker, the ultrasonic vibrator device 20 is connected to the base 10 so that the pressure cooker is formed as an ultrasonic pressure cooker, and the blocking member 30 is connected to the base 10 instead of the ultrasonic vibrator device 20 so that the pressure cooker can perform the function of a general pressure cooker.

The above-described configuration can be applied not only to detachable attachment of the ultrasonic transducer device 20 but also to detachable attachment of other structures. For example, in some embodiments, the safety valve assembly 110, the exhaust valve assembly 120, the sensor assembly, and the like may be detachably mounted to the base 10, and after the safety valve assembly 110, the exhaust valve assembly 120, or the sensor assembly is detached from the base 10, the installation recess of the safety valve assembly 110, the exhaust valve assembly 120, or the sensor assembly on the base 10 may be blocked by a blocking member, so that the apparatus having the installation structure of the ultrasonic device may normally operate.

The mounting structure of the ultrasonic device according to the embodiment of the invention is detachably connected with the base 10 through the ultrasonic vibrator device 20 and the plugging piece 30, the cleaning is convenient, and the plugging piece 30 can plug the notch of the mounting concave part 101, the structure is more beautiful and firm, so that the equipment with the mounting structure of the ultrasonic device can normally work.

According to some embodiments of the present invention, as shown in fig. 5 to 7, the ultrasonic transducer device 20 may be connected to the base 10 through a first rotary clamping structure, and the connection structure between the ultrasonic transducer device 20 and the base 10 is simple and easy to disassemble and assemble.

According to some embodiments of the present invention, the blocking member 30 may be connected to the base 10 by a second rotary clamping structure, and optionally, the first rotary clamping structure and the second rotary clamping structure may have the same structure. That is, the attaching and detaching structure of the sealing material 30 and the base 10 and the attaching and detaching structure of the ultrasonic transducer device 20 and the base 10 may be the same. After the ultrasonic transducer device 20 is separated from the base 10, the sealing material 30 is fixed by the detachable structure of the ultrasonic transducer device 20, which is advantageous in simplifying the structure of the base 10, and also in facilitating the sealing of the notch of the mounting recess 101 by the sealing material 30, which is advantageous in improving the sealing property.

It should be noted that, in the drawings, only a schematic structural diagram of the connection between the ultrasonic transducer device 20 and the base 10 through the first rotary clamping structure is shown, and the structure of the blocking piece 30 is the same as the structure of the connection between the blocking piece 30 and the base 10 through the second rotary clamping structure, so it is easy for those skilled in the art to understand the structure of the connection between the blocking piece 30 and the base 10 after reading the technical solution of the present invention.

In some embodiments of the present invention, as shown in fig. 8 to 10, the mounting recess 101 may be a through hole penetrating the base 10, and the ultrasonic vibrator device 20 may be inserted into the through hole, so that the ultrasonic vibrator device 20 may be connected to the base 10. When the ultrasonic transducer device 20 is connected to the base 10, the electrical connection structure of the ultrasonic transducer device 20 can be located on the upper side of the base 10, and the electrical connection structure can be prevented from being wetted by vapor or liquid in the apparatus having the mounting structure of the ultrasonic transducer device and short-circuited.

In addition, as shown in fig. 6 and 7, the first rotary clamping structure may include: a first stopper protrusion 41, a first catching protrusion 42, and a catching piece 43. The outer peripheral surface of the ultrasonic transducer device 20 may be provided with a first stopper protrusion 41, and the outer peripheral surface of the ultrasonic transducer device 20 may be provided with a first engaging protrusion 42. When the ultrasonic vibrator device 20 is inserted into the through hole, the clip 43 may be externally fitted to the ultrasonic vibrator device 20.

As shown in fig. 7 and 16 to 18, the inner circumferential surface of the clip 43 may have an inner clip protrusion 431 protruding inward, and the ultrasonic transducer device 20 and the clip 43 may rotate relative to each other, so that when the ultrasonic transducer device 20 is connected to the base 10, the inner clip protrusion 431 may move to a position below the first clip protrusion 42, the inner clip protrusion 431 abuts against the first clip protrusion 42, the lower circumferential edge of the through hole abuts against the first stopper protrusion 41, and the upper circumferential edge of the through hole abuts against the clip 43.

From this, the cooperation of the last week edge of joint spare 43, first joint convex part 42 and through-hole can prevent that the ultrasonic vibrator device 20 from deviating from by the upside of through-hole, and the cooperation of the lower week edge of first backstop convex part 41 and through-hole can prevent that the ultrasonic vibrator device 20 from deviating from by the downside of through-hole, and the ultrasonic vibrator device 20 is firm with the base 10 joint.

In some embodiments, when mounting, the ultrasonic transducer device 20 may be first inserted into the through hole from the lower side of the base 10, so that the first stopping protrusion 41 abuts against the lower periphery of the through hole; then, the clamping piece 43 is sleeved on the ultrasonic vibrator device 20 from the upper side of the base 10; the clamping piece 43 is rotated to enable the inner clamping protrusion 431 to move to the position between the upper peripheral edge of the through hole and the first clamping protrusion 42, and the clamping piece 43, the first clamping protrusion 42 and the upper peripheral edge of the through hole are abutted to achieve axial fixing of the ultrasonic vibrator device 20. When the ultrasonic vibrator device 20 needs to be detached, the clamping piece 43 can be rotated reversely, the inner clamping protrusion 431 is moved out from between the upper peripheral edge of the through hole and the first clamping protrusion 42, the clamping piece 43 is taken down, and then the ultrasonic vibrator device 43 is moved out of the through hole downwards. The ultrasonic vibrator device 20 is simple in mounting and dismounting process, and simple and firm in mounting structure.

In addition, in the embodiment that the device with the ultrasonic device mounting structure is a pressure cooker, the pressure in the working chamber of the pressure cooker is increased to form a positive pressure, the positive pressure pushes the ultrasonic vibrator device 20 outwards, the first stopping convex part 41 can be abutted against the lower peripheral edge of the through hole to provide better strength and stability, the ultrasonic vibrator device 20 is prevented from being separated from the through hole outwards, and meanwhile, the positive pressure can increase the abutting effect of the first stopping convex part 41 against the lower peripheral edge of the through hole, so that the sealing effect is improved.

According to a further embodiment of the present invention, as shown in fig. 8 to 10, the inner circumferential surface of the through hole may be provided with a positioning concave portion 102, and as shown in fig. 11 to 13, the outer circumferential surface of the ultrasonic vibrator device 20 may be provided with a first positioning convex portion 44. As shown in fig. 7, when the ultrasonic transducer device 20 is inserted into the through hole, the first positioning protrusion 44 is formed as a snap, the positioning recess 102 is formed as a bayonet, and the first positioning protrusion 44 can be engaged with the positioning recess 102 to limit the ultrasonic transducer device 20 in the circumferential direction of the through hole, so that the ultrasonic transducer device 20 is prevented from rotating relative to the base 10, and the fixation is more stable and firm. At this moment, can realize the joint through rotating joint spare 43 to when joint spare 43 rotated, need not manually to carry out circumference location to ultrasonic vibrator device 20, first rotatory joint structure joint is more convenient.

Of course, the positions of the first positioning convex portion 44 and the positioning concave portion 102 may be interchanged, specifically, the inner circumferential surface of the through hole may be provided with the first positioning convex portion 44, and the outer circumferential surface of the ultrasonic transducer device 20 may be provided with the positioning concave portion 102, which may also enable the first positioning convex portion 44 and the positioning concave portion 102 to cooperate to realize the circumferential limit of the ultrasonic transducer device 20.

In some embodiments, the extension length of the positioning recess 102 along the circumferential direction of the through hole may be 0mm to 10mm, excluding 0mm, so as to prevent the extension length of the positioning recess 102 from being too long, which may cause the circumferential direction of the through hole between adjacent positioning recesses 102 to be too short, thereby affecting the structural strength or the sealing performance. For example, in some specific embodiments, the extension lengths of the positioning recess 102 in the circumferential direction of the through hole may be 1mm, 3mm, 5mm, 7mm, 9mm, and the like, respectively. Further, the extension length of the positioning recess 102 in the circumferential direction of the through hole may be 0.5mm to 5 mm.

Alternatively, in the present invention, the bayonet shape of the positioning concave portion 102 may be an arc shape, a circular shape, a square shape, a diamond shape, an irregular shape, or the like, and the fastening shape of the first positioning convex portion 44 is an arc-shaped protrusion, a circular protrusion, a square protrusion, a diamond-shaped protrusion, an irregular protrusion, or the like corresponding to the bayonet shape of the positioning concave portion 102.

Further, the first snap protrusion 42 and the inner snap protrusion 431 may include a plurality corresponding one to each other, for example, the first snap protrusion 42 and the inner snap protrusion 431 may include two, three, or more, respectively. The plurality of first click projections 42 may be provided at intervals in the circumferential direction of the ultrasonic transducer device 20. When being installed, each inner snap protrusion 431 can pass through between two adjacent first snap protrusions 42 and move to the lower side of the first snap protrusion 42, and at this time, the circumferential positions of the inner snap protrusions 431 and the first snap protrusions 42 do not correspond. When the first rotary clamping structure is clamped, the clamping piece 43 rotates relative to the ultrasonic vibrator device 20, and each inner clamping protrusion 431 can move to the lower side of the corresponding first clamping protrusion 42, so that the clamping of the inner clamping protrusions 431 and the first clamping protrusions 42 is realized.

Alternatively, an upper side of each inner catching protrusion 431 may abut against a lower side of the corresponding first catching protrusion 42, and a lower side of each inner catching protrusion 431 may abut against at least one of an upper side of the first positioning protrusion 44 and an upper peripheral edge of the through hole.

Still further, as shown in fig. 11 and 16, the first positioning protrusion 44, the first snap protrusion 42, and the inner snap protrusion 431 may include a plurality of one-to-one correspondence with each other, for example, the first positioning protrusion 44, the first snap protrusion 42, and the inner snap protrusion 431 may include two, three, or more, respectively. The plurality of first positioning protrusions 44 and the first clamping protrusions 42 may be spaced apart from each other in the circumferential direction of the ultrasound transducer apparatus 20, and when the first rotary clamping structure is clamped, each of the inner clamping protrusions 431 may move into a gap between the corresponding first positioning protrusion 44 and the corresponding first clamping protrusion 42.

In some embodiments, as shown in fig. 7, when the first positioning protrusion 44 is engaged with the positioning recess 102, the upper side of the first positioning protrusion 44 is lower than the upper peripheral edge of the through hole, and when the inner snap protrusion 431 moves to the gap between the first positioning protrusion 44 and the first snap protrusion 42, the lower side of the inner snap protrusion 431 abuts against the upper edge of the positioning recess 102, so that the axial position limitation of the ultrasonic transducer device 20 is more stable.

According to some embodiments of the present invention, as shown in fig. 11, the first clamping protrusion 42 may be a long strip extending along the circumferential direction of the ultrasonic vibrator device 20, one circumferential end of the lower side surface of the first clamping protrusion 42 may be inclined with respect to the axial direction of the through hole to form a first guiding inclined surface 421, the first guiding inclined surface 421 may guide the inner clamping protrusion 431 to move towards the lower side of the first clamping protrusion 42, and the inner clamping protrusion 431 is easier to clamp with the first clamping protrusion 42.
