Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0041] like Figures 1 to 7 As shown, according to an embodiment of the present invention, a handheld electric cleaning device is provided, comprising:

[0042] Handle 1;

[0043] The fuselage 2 has one end extending into the handle 1, and the fuselage 2 has a receiving cavity;

[0044] Cleaning component 3 includes: a miniature DC appliance 301, a miniature vibrator 302, an ultrasonic generator 303, and a brush 304. The miniature DC appliance 301 is disposed inside the handle 1, and its driving end is connected to one end of the body 2.

[0046] The electronic control component 5 includes: a rotary switch button 5011, a drying switch button 5012, an integrated circuit board 502, and a power supply 503. The rotary switch button 5011 and the drying switch button 5012 are disposed on the outer wall of the handle 1, and the power supply 503 and the integrated circuit board 502 are disposed inside the handle 1. The power supply 503, the rotary switch button 5011, the drying switch button 5012, and the integrated circuit board 502 are electrically connected, and the integrated circuit board 502 is electrically connected to a miniature DC appliance 301, a miniature vibrator 302, an ultrasonic generator 303, a fan 401, and a heating resistance wire 402.

[0047] Specifically, the components housed within the handle 1 include a power supply 503, an integrated circuit board 502, a fan 401, and a miniature DC power supply 301. The power supply 503 provides electrical energy to power the components. The integrated circuit board 502, a PCB circuit board, can output various control commands. The fan 401 draws external air into the device.

[0048] One end of the machine body 2 extends into the handle 1 and is connected to the drive end of the miniature DC electrical appliance 301. The miniature DC electrical appliance 301 drives the machine body 2 to rotate, which in turn rotates the brush 304 mounted on the machine body 2 to perform cleaning. Furthermore, a lubricating coating is provided at the connection between the machine body 2 and the lower end of the handle 1, preventing water from splashing into the handle 1 during cleaning and ensuring that the machine body 2 does not cause wear to the handle 1 during rotation. The main components housed within the machine body 2 include a miniature vibrator 302, an ultrasonic generator 303, and a heating resistance wire 402. The heating resistance wire 402 is located close to the air outlet 404, enabling it to promptly heat the air introduced by the fan 401 into hot air for delivery, thus improving drying efficiency. The synergy between the miniature vibrator 302 and the ultrasonic generator 303 significantly improves cleaning efficiency and the degree of cleanliness. Rotating switch button 5011 can control the operation of fan 401, miniature DC appliance 301, miniature vibrator 302 and ultrasonic generator 303, while drying switch button 5012 can control the operation of fan 401 and heating resistance wire 402.

[0049] Specifically, when using the cleaning function, the container is cleaned by the rotation of the brush 304 and with the assistance of the micro vibrator 302 and the ultrasonic generator 303. The ultrasonic generator 303 utilizes the "cavitation effect" generated by high-frequency sound waves in the liquid to achieve efficient cleaning.

[0050] When using the drying function, remove the brush 304, and the heating resistance wire 402 and fan 401 will run, with hot air output through the air outlet 404.

[0051] In this embodiment, the cleaning device provides a miniature vibrator 302 and an ultrasonic generator 303, which can greatly improve the cleaning efficiency and cleanliness. At the same time, this application also provides a drying component in the device. After cleaning, the brush 304 can be directly removed and the machine body 2 can be inserted into the cleaned container for drying.

[0052] In one embodiment, the handle 1 is provided with a groove 504 for hand gripping, and a pressure sensor is provided in the groove 504. The pressure sensor is connected to the integrated circuit board 502. The pressure sensor is adapted to sense the hand gripping pressure at the groove 504 and transmit the hand gripping pressure to the integrated circuit board 502. The integrated circuit board 502 is adapted to control the rotation speed of the micro DC electrical appliance 301 and the temperature of the heating resistance wire 402 according to the hand gripping pressure.

[0053] In this embodiment, a pressure sensor detects the amount of hand pressure. Thus, when using the cleaning function, the rotation speed of the miniature DC appliance 301 can be adjusted by changing the amount of hand pressure; when using the drying function, the temperature of the heating resistance wire 402 can be adjusted by changing the amount of hand pressure.

[0054] In one embodiment, a copper ring 505 is provided at one end of the device body 2, and a carbon brush 506 is provided on one side of the copper ring 505 in contact with it. The carbon brush 506 is connected to the integrated circuit board 502 through the control bus 507. The micro vibrator 302, the ultrasonic generator 303 and the heating resistance wire 402 are connected to the copper ring 505 through the control branch line 508.

[0055] In this embodiment, carbon brushes 506 and copper rings 505 are used as electrical transmission devices between rotating and stationary components to achieve reliable sliding electrical connection. Six copper rings 505 are provided and are connected to the micro vibrator 302, ultrasonic generator 303, and heating resistance wire 402 respectively through control branch lines 508, so that each component can work independently. The control branch lines 508 and the control bus 507 are connected to the copper rings 505 through carbon brushes 506, so that both transmission and conduction can be carried out normally.

[0056] In one embodiment, the rotary switch button 5011 and the drying switch button 5012 are connected to the integrated circuit board 502 via a multi-control switch 5013 inside the handle 1; both the rotary switch button 5011 and the drying switch button 5012 are connected to the fan 401. That is, when the rotary switch button 5011 is pressed, the integrated circuit board 502 controls the fan 401 and the cleaning component to operate, and the fan 401 can dissipate heat from the cleaning component in a timely manner. When the drying switch button 5012 is pressed, the integrated circuit board 502 controls the fan 401 and the heating resistance wire 402 to operate, and the fan 401 introduces airflow and outputs the airflow from the air outlet 404 to complete the drying work.

[0057] In one embodiment, a fan 401 is disposed inside the handle 1 at one end away from the body 2, and an air inlet 403 is provided on the outer wall of the handle 1 at one end away from the body 2.

[0058] In this embodiment, the air inlet 403 ensures that the airflow inside the device can flow normally; the fan 401 is located inside the handle 1 at the end away from the body 2. On the one hand, it can dissipate heat from the internal components of the handle 1 in time when the device is cleaning, and on the other hand, it can allow the airflow to pass smoothly through the first air passage 405, the second air passage 406, and the heating resistance wire 402 before outputting hot air through the air outlet 404 during the drying operation.

[0059] In one embodiment, a first air passage 405 is provided at one end of the body 2 that extends into the handle 1, a partition 101 is provided at the bottom inside the handle 1, a miniature DC electrical appliance 301 is provided on the partition 101, and a second air passage 406 is provided on the partition 101.

[0060] In this embodiment, the first air passage 405 and the second air passage 406 can ensure that the air blown out by the fan 401 can smoothly enter the body 2, and after passing through the heating resistance wire 402, the hot air is output through the air outlet 404; the miniature DC electrical appliance 301 is set on the partition 101, and the partition 101 is fixed to the handle 1, which can ensure that during the cleaning process, the miniature DC electrical appliance 301 drives the body 2 to rotate smoothly.

[0061] In some embodiments, the power supply 503 is a series of dry cell batteries, or the power supply 503 is a rechargeable lithium battery.

[0062] In this embodiment, the power source 503 can be multiple dry cell batteries connected in series, and a battery compartment 5032 is provided inside the handle 1. In other embodiments, the power source 503 is a rechargeable lithium battery disposed in the battery compartment 5032, and a charging port 5031 is provided on the handle 1 for connection, preferably a USB charging port.

[0063] In one embodiment, the upper and lower ends of the outer wall of the body 2 are provided with buckles 201 suitable for connecting brushes 304. The brushes 304 include, but are not limited to, beaker brushes, test tube brushes, and volumetric flask brushes.

[0064] In this embodiment, during the cleaning process, the brush 304 is fixed to the machine body 2 by the buckle 201 to ensure a stable connection between the brush 304 and the machine body 2 during the cleaning process. Different brushes 304 can be selected to meet the cleaning needs of different containers. The brush 304 can be removed during the drying process.

[0065] Specifically, the working process of the cleaning device in this application is as follows:

[0066] During cleaning, install the appropriate brush 304 as needed, insert the machine body 2 into the container to be cleaned, and press the rotation switch button 5011. The miniature DC motor 301 drives the machine body 2 and the brush 304 fixed on the machine body 2 to rotate. The miniature vibrator 302 and the ultrasonic generator 303 inside the machine body 2 operate. The brush 304, the miniature vibrator 302, and the ultrasonic generator 303 work together to clean the container. During cleaning, the dirt in the container is unevenly distributed. For areas with more dirt, the rotation speed of the brush 304 can be adjusted by increasing the pressure of the hand grip. At the same time, the fan 401 runs to dissipate heat from the components inside the handle 1.

[0067] After the cleaning is completed, the drying process can begin. First, remove the brush 304 and check if the air outlet 404 is blocked. Insert the machine body 2 into the container to be dried and press the drying switch button 5012. At this time, the heating resistance wire 402 and the fan 401 will run. The airflow generated by the fan 401 enters the machine body 2 through the first air outlet 405 and the second air outlet 406. The airflow passes through the heating resistance wire 402 to form hot air, which is output from the air outlet 404 to dry the water stains. For areas with more water stains, the temperature of the heating resistance wire 402 can be adjusted by increasing the pressure of the hand grip.

[0068] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
