Description

Technical Field

[0001] This utility model relates to the field of small household appliances, and in particular to an ultrasonic cleaner. Background Technology

[0002] Currently, for regular consumers, ultrasonic cleaners are typically used to clean relatively valuable or delicate items such as lenses and jewelry. After cleaning, the water inside the ultrasonic cleaner needs to be poured out, but some liquid remains inside, which can easily breed bacteria and pests.

[0003] To reduce residual liquid, some ultrasonic cleaners incorporate fans to accelerate drying after cleaning. For example, utility model patent CN202323125285.5 discloses an ultrasonic cleaner that facilitates drying by incorporating a drying fan on the top cover. After cleaning, the fan activates to quickly dry the inner tank, preventing residual liquid. However, this ultrasonic cleaner only discloses an air inlet on the top cover, lacking an outlet. During drying, the flow of air inside and outside the ultrasonic cleaner is obstructed, especially since the top cover has a first and second sealing ring, further hindering airflow and reducing drying efficiency. Even if opening the top cover during drying solves the airflow problem, the flip-top design (one edge of the top cover is rotatably connected to the lower shell) causes the drying fan to tilt, deflecting airflow towards the inner tank's side wall near the opening. This creates a dead zone on the other side of the inner tank, further reducing drying efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes an ultrasonic cleaner that employs a detachable cover structure. Combined with a fan on the cover and fluid gaps around it, it ensures normal airflow inside and outside the product, achieving a quick-drying effect.

[0005] This utility model provides the following technical solution:

[0006] An ultrasonic cleaner includes a housing, a cleaning inner tank embedded in the housing, an assembly space formed between the housing and the cleaning inner tank, and an ultrasonic generator located in the assembly space.

[0007] It also includes a cover, which is separable from the housing. When the cover is placed on the housing, a cleaning space is formed between the cover and the inner cleaning tank. The cover is provided with a drying channel, and a fan is provided in the drying channel.

[0009] Furthermore, the housing has an upper surface that extends generally horizontally around the periphery of the inner cleaning tank, and a plurality of support members are provided between the cover and the upper surface of the housing to form a fluid gap between the cover and the upper surface of the housing.

[0010] Furthermore, the lower surface of the cover is provided with several grooves, the upper end of the support extends into the grooves, and the depth of the grooves is less than the height of the support.

[0011] Furthermore, the upper surface of the housing has a raised edge surrounding its periphery. When the cover is placed on the housing, the raised edge surrounds the periphery of the cover, and the height of the top of the raised edge is higher than the height of the bottom surface of the housing.

[0012] Furthermore, the drying channel is a through hole provided on the cover, and the drying channel is located at the center of the cover.

[0013] Furthermore, protective nets are installed at both ends of the air-drying channel, and the fan is located between the two protective nets.

[0032] Please see Figures 1-6

[0033] An ultrasonic cleaner includes a housing 1, a cleaning inner tank 2 embedded in the housing 1, an assembly space formed between the housing 1 and the cleaning inner tank 2, and an ultrasonic generator 3 located in the assembly space. The ultrasonic waves emitted by the ultrasonic generator 3 induce cavitation effects in the water through the cleaning inner tank 2 and act on the items to be cleaned, thereby achieving a cleaning effect.

[0034] It also includes a cover 4, which is separable from the housing 1, so that the cover 4 can be completely detached from the housing 1 after being opened; and when the cover 4 is placed on the housing 1, a cleaning space is formed between the cover 4 and the inner cleaning tank 2. The cover 4 is provided with a drying channel 6, and a fan 7 is provided in the drying channel 6. When the fan 7 is running, it can provide forced ventilation to the cleaning space to achieve a quick drying effect. When the cover 4 is detached from the housing 1, the fan 7 is also detached from the housing 1. At this time, the user can adjust the position of the cover 4 and the fan 7 at will to adjust the flow direction of the airflow generated by the fan 7, so as to target and quickly dry each corner of the inner cleaning tank 2 as needed, reduce dead corners, and make the quick drying more comprehensive.

[0035] It also includes a fluid gap 9, the cleaning space and the drying channel 6 are connected in sequence to form a channel for the flow of internal and external gas. Both ends of the channel are connected to the outside, which can ensure the normal flow of gas inside and outside the cleaning space when the cover 4 covers the shell 1, so as to achieve the effect of quick drying.

[0036] In a preferred embodiment, the housing 1 has an upper surface 101 that extends horizontally around the periphery of the inner cleaning tank 2. A plurality of support members 8 are provided between the cover 4 and the upper surface 101 of the housing to form a fluid gap 9 between the cover 4 and the upper surface 101 of the housing, through which the gas in the cleaning space can exchange with the outside gas.

[0037] The support member 8 is a structure that is partially raised upward on the upper surface 101 of the shell, and there are at least two of them, located on both sides of the upper surface 101 of the shell respectively.

[0038] In a preferred embodiment, the lower surface of the cover 4 is provided with a plurality of grooves 401, the upper end of the support member 8 extends into the grooves 401, and the depth of the grooves 401 is less than the height of the support member 8, so that the cover 4 can be lifted by the support member 8, so that there is a certain gap between the lower surface of the cover 4 and the upper surface 101 of the shell, forming a fluid gap 9; the support member 8 extending into the grooves 401 can also play a positioning role, restricting the degree of freedom of the cover 4 in the horizontal direction.

[0039] In this embodiment, there are three of each of the support members 8 and the grooves 401. One of them is located on one side of the upper surface 101 of the housing, and the other two are located on the other side of the upper surface 101 of the housing. The support is more balanced and can prevent the cover 4 from tilting when it is placed on the housing 1.

[0040] In a preferred embodiment, the upper surface 101 of the housing has a raised edge 10 surrounding its periphery. When the cover 4 is placed on the housing 1, the raised edge 10 surrounds the periphery of the cover 4, and the height of the top of the raised edge 10 is higher than the height of the bottom surface of the housing 1. The side of the raised edge 10 near the cover 4 is a sloping surface, which facilitates guiding the cover 4 to be placed directly above the housing 1 and can also improve the smoothness of gas flow. Furthermore, when the support member 8 extends into the groove 401, it can position the cover 4, preventing the outer periphery of the cover 4 from contacting the sloping surface of the raised edge 10, and ensuring that a gap is formed between the sloping surface of the raised edge 10 and the outer periphery of the cover 4 to allow gas to flow through.

[0041] In a preferred embodiment, the drying channel 6 is a through hole provided on the cover 4, and the drying channel 6 is located at the center of the cover 4.

[0042] In a preferred embodiment, protective nets 601 are provided at both ends of the drying channel 6, and the fan 7 is located between the two protective nets 601. The protective nets 601 can effectively protect the fan blades of the fan 7 and prevent interference with people or other objects.

[0043] In a preferred embodiment, a magnetic attraction assembly is provided between the cover 4 and the upper surface 101 of the housing, which can improve the stability of the cover 4 when it is placed on the upper surface 101 of the housing and effectively prevent the cover 4 from detaching from the housing 1 under the action of airflow.

[0044] In a preferred embodiment, the magnetic attraction component includes a first magnet and a corresponding adsorbent, wherein the adsorbent includes a second magnet or a magnetically attractable metal object, and one of the first magnet or the adsorbent is disposed within the support member 8.

[0045] In one embodiment, the first magnet is disposed within the support member 8, and the second magnet or a magnetically attracted metal object is disposed within the cover 4 at a position corresponding to the groove 401.

[0046] In another embodiment, the second magnet or a magnetically attracted metal object is disposed within the support member 8, and the first magnet is disposed within the cover 4 at a position corresponding to the groove 401.

[0047] In a preferred embodiment, the upper surface 101 of the housing is provided with conductive contacts 5, and the lower surface of the cover 4 is provided with a circuit connected to the conductive contacts 5. When the cover 4 is placed on the housing 1 and the upper end of the support 8 extends into the corresponding groove 401, the conductive contacts 5 contact the circuit on the lower surface of the cover 4 to form a circuit.

[0048] Specifically, in this embodiment, the ultrasonic generator 3 and the fan 7 are powered by a battery or an external wire. When the cover 4 is placed on the housing 1, the conductive contact 5 contacts the circuit on the lower surface of the cover 4 and forms a circuit. In this way, the ultrasonic generator 3 and the fan 7 can be powered simultaneously, regardless of whether the battery is placed inside the housing 1 or the cover 4.

[0049] In a preferred embodiment, the cleaning inner tank 2 includes a tank body 201 and a mesh basket 202, wherein the tank body 201 is embedded in the shell 1 and is used to contain cleaning liquid; the mesh basket 202 is placed in the tank body 201, and the bottom of the mesh basket 202 is provided with several support feet 203.

[0050] Specifically, the support foot 203 raises the bottom of the basket 202 to a certain height. The items to be cleaned are placed in the basket 202, and most of the bottom surface of the items is exposed by the holes on the bottom surface of the basket 202, which can reduce the blind spots in cleaning the items. In addition, since there is a gap between the bottom surface of the basket 202 and the bottom surface of the inner wall of the cleaning liner 2, the airflow can flow to the bottom surface of the basket 202 during quick drying, which effectively ensures the quick drying effect.

[0051] Working principle:

[0052] During the cleaning process, the ultrasonic waves emitted by the ultrasonic generator 3 induce cavitation in the water through the inner cleaning tank 2, thereby cleaning the items soaked in the water in the inner cleaning tank 2. After cleaning, the cover 4 is opened and the water in the inner cleaning tank 2 is poured out. Then the cover 4 is closed again, and the fan 7 is turned on to provide forced ventilation to the cleaning space. The gas in the cleaning space exchanges with the outside air through the fluid gap 9 and the drying channel 6 to form an airflow and achieve a quick-drying effect.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
