Description

TECHNICAL FIELD

[0001] The utility model relates to the field of household appliances, especially a cleaning bin for cleaning the air inlet of a hair dryer. BACKGROUND

[0002] With the continuous improvement of living quality, hair dryers have long been an indispensable necessity in life. In the prior art, during use, dust and debris in the air will enter the hair dryer along with the airflow through the air inlet net and filter screen at the air inlet, and will be adsorbed on the fan, air inlet net, filter screen and other components. The filter screen hole is small and dense, and is more likely to be blocked by dust. Over time, this will affect the function of the components of the hair dryer. Existing hair dryers either have no cleaning function or require the joint action of several keys to achieve the cleaning function, which is very inconvenient to operate.

[0003] The prior art CN215382002U discloses a "hair dryer cleaning system", and specifically discloses a hair dryer cleaning system. The hair dryer includes a handle portion and a fan portion, and the fan portion has an air inlet and an air outlet at its two ends. The handle portion is externally provided with a cleaning key for controlling the reverse rotation of the fan motor and a cleaning indicator light. The mainboard inside the handle portion is provided with an MCU, a self-heating body, a temperature detection circuit and a motor steering control circuit. During operation of the hair dryer, when the MCU on the mainboard detects an abnormality in the resistance value of the self-heating body through the temperature detection circuit, the MCU controls the cleaning indicator light to light up, reminding the user that the hair dryer needs to be cleaned. At this time, the hair dryer is restored to a standby state, the cleaning key is pressed, the MCU controls the motor steering control circuit to make the motor reverse, and the dust and debris at the air inlet position are discharged by the reverse air flow, thereby achieving the purpose of cleaning. It is also mentioned that the air inlet is provided with an air inlet net and a filter screen. Since the filter screen hole is small and dense, dust and debris in the air are easily blocked on the filter screen. In the cleaning state, the motor is reversed, the fan is instantly driven, and the fan air flow is used for cleaning. At this time, the air outlet becomes the air inlet, and the air inlet becomes the air outlet, so that the dust and debris adsorbed on the components of the hair dryer can be blown out of the hair dryer, thereby achieving the purpose of cleaning.

[0004] In the above application, the air inlet is changed into an air outlet by reversing the motor, so that the dust adsorbed on the air inlet is blown out into the air, but this way not only makes the dust be blown back into the air, causing a bad user experience, but also the user will have some hair loss and hair shedding during the process of using the hair dryer to dry the hair. Since the air flow rate at the air inlet is large, a negative pressure will be generated at this place, causing the adsorption of the hair loss and hair shedding, and the reverse blowing way cannot blow out the hair loss and hair shedding wrapped on the filter screen at the air inlet. In the above application, when the temperature detection circuit detects that the self-heating body resistance value is abnormal, the cleaning indicator light is turned on to remind the user that the hair dryer needs to be cleaned. This way is easy to cause the self-heating body to overheat due to circuit failure during user use, which not only has certain safety hazards but also has a complex circuit.

[0033] The technical scheme of the utility model will be described in detail below with specific examples. The following specific examples can be combined or replaced according to actual conditions, and the same or similar concepts or processes may not be described in some examples.

[0034] As shown in Figure 1 A cleaning bin for cleaning the air inlet 41 of the hair dryer 4, comprising a bin body 3 and a cleaning assembly and a dust collecting box 31 arranged on the bin body 3, the cleaning assembly comprising a rotating brush assembly 1 and a cyclone separation assembly 2, the rotating brush assembly 1 comprising a rotating brush 11 and a first motor 12 driving the rotating brush 11 to rotate and clean the air inlet 41 of the hair dryer 4, the cyclone separation assembly 2 comprising a cyclone cavity 21 and a fan 22, the bin body 3 being provided with a dust removal air duct 32, the inlet of the dust removal air duct 32 being connected with the air inlet 41 of the hair dryer 4, the rotating brush 11 being arranged at the inlet of the dust removal air duct 32, the outlet of the dust removal air duct 32 being arranged on the surface of the bin body 3, and the cyclone separation assembly 2 being arranged in the dust removal air duct 32 to separate dust and air and gather dust in the dust collecting box 31.

[0035] Understandably, the chamber 3 is equipped with a dust removal duct 32. The inlet of the dust removal duct 32 is connected to the air inlet 41 of the blower 4. The inlet of the dust removal duct 32 is equipped with a rotating brush assembly 1. Driven by the first motor 12, the rotating brush 11 rotates at the air inlet 41 of the blower 4 to clean the air inlet 41. The rotating brush 11 can brush away the hair and dust clogging the air inlet 41, causing the hair and dust to fall into the dust removal duct 32. The dust removal duct 32 is also equipped with a cyclone separator assembly 2 for separating dust and air in the dust removal duct 32. The fan 22 of the cyclone separator assembly 2 draws the air in the dust removal duct 32 into the cyclone separator assembly 32. The air enters the cyclone chamber 21, where it forms a rotating airflow. Under the action of centrifugal force, the dust and hair in the air are thrown towards the inner wall of the cyclone chamber 21. Finally, the dust and hair are thrown into the dust collection box 31 located in the chamber 3 along the inner wall of the cyclone chamber 21. The clean air after dust and air separation is blown out through the outlet of the dust removal air duct 32 located on the surface of the chamber 3. This structure can clean the air inlet 41 of the blower 4 while collecting the cleaned dust. The addition of the dust collection box 31 makes it more convenient for users to clean it and avoids the air with dust and hair being blown back into the air, which would cause a bad user experience.

[0036] In order for the rotating brush 11 to better clean the air inlet 41 of the hair dryer 4, the rotating brush 11 includes an annular brush body 111 and bristles 112 bundled and fixed to the brush body 111. The bristles 112 are spirally arranged in multiple rows along the axis of the brush body 111.

[0037] The advantage of this design is that the annular brush body 111 facilitates the insertion of the air inlet 41 of the hair dryer 4, allowing the rotating brush 11 to better fit around the outer periphery of the air inlet 41. The bristles 112, which are bundled and fixed to the brush body 111, can not only clean every corner of the air inlet 41 meticulously, but also the bristles 112 are relatively soft and will not scratch the air inlet 41 during the cleaning process. The axial spiral arrangement of the bristles 112 ensures that each row of bristles 112 can effectively clean different areas of the air inlet 41 during the rotation process, covering the entire surface of the air inlet 41. This avoids cleaning dead spots caused by the positional deviation of the bristles 112 during the cleaning process, ensuring thorough cleaning.

[0038] In addition, the chamber 3 is equipped with a safety switch 33. To make the internal structure of the chamber 3 compact, reduce the weight of the entire cleaning chamber, and minimize the use of the limited space inside the chamber, making it lighter overall, a micro switch is used for the safety switch 33 in this embodiment. The safety switch 33 is only triggered after the hair dryer 4 is installed in the chamber 3. The safety switch 33 can also be a magnetic switch, such as a reed switch, with a magnet on the hair dryer. When the magnet approaches the magnetic switch, it will trigger the magnetic switch.

[0039] The cleaning chamber is only triggered when the hair dryer 4 is correctly installed in the chamber 3. The safety switch 33 prevents the cleaning chamber from operating accidentally when the hair dryer 4 is not correctly installed in the cleaning chamber, reducing safety risks or poor user experience caused by improper operation.

[0040] The chamber 3 is equipped with a PCB board 34 for controlling the first motor 12 and the fan 22 to be electrically connected to the safety switch 33. The PCB board 34 is fixed inside the main body. In this embodiment, when the blower 4 is correctly installed in the chamber 3 and the safety switch 33 is triggered, the first motor 12 and the fan 22 will be started at the same time.

[0041] In other embodiments, the first motor 12 and the fan 22 can also be set to start separately. For example, the fan 22 can be started first, so that the floating dust at the air inlet 41 of the blower 4 can be sucked into the cyclone separator 2, and then the first motor 12 can be started to drive the rotating brush 11 to rotate and clean the air inlet 41 of the blower 4, which can appropriately reduce the burden on the rotating brush 11; or, the first motor 12 can be started first to clean the dust and hair at the air inlet 41 of the blower 4, and then the fan 22 can be started to separate the dust and air.

[0042] It should be noted that the chamber 3 is provided with an installation port 351 for the head of the blower 4 to be inserted and positioned. The air inlet 41 of the blower 4 is provided with a filter screen 411, which extends into the installation port 351. The rotating brush 11 is fitted around the outer periphery of the filter screen 411.

[0043] Thus, when the user needs to clean the hair dryer 4, they only need to align the head of the hair dryer 4 with the mounting port 351 of the chamber 3 for insertion and positioning. The installation is simple and convenient. The air inlet 41 of the hair dryer 4 is equipped with a filter 411 to prevent dust and hair from entering the hair dryer 4. When the head is inserted into the mounting port 351, the filter 411 will extend into the mounting port 351. At this time, the rotating brush 11 in the cleaning chamber is fitted around the outer periphery of the filter 411. When the first motor 12 drives the rotating brush 11, as the rotating brush 11 rotates, it will generate friction with the surface of the filter 411, thereby effectively removing the dust and hair attached to the surface of the filter 411 and thoroughly cleaning the surface of the filter 411.

[0044] Specifically, the top of the compartment 3 is detachably connected to a cover 35. The cover 35 and the compartment 3 can be connected in the following ways, all of which can achieve the purpose of detachment: threaded connection, snap-fit, etc.

[0045] Furthermore, the cover 35 covers the rotating brush 11, and the mounting port 351 is located on the cover 35.

[0046] This structure allows for easy installation of the cleaning chamber. Since the cover 35 is detachably connected to the chamber body 3, and the mounting port 351 is located on the cover 35, the user can first install the cover 35 onto the machine body, then align the rotating brush 11 with the cover 35 to connect the entire chamber body 3 to the cover 35. This improves the accuracy and convenience of installing the rotating brush 11. When the cleaning chamber is in operation, because the cover 35 covers the rotating brush 11, cleaning the filter 411 of the machine body prevents the cleaned dust from falling into the air, allowing the dust to move along... The cover 35 enters the dust removal air duct 32. When the cleaning chamber is not in operation, the cover 35 covers the rotating brush 11, which can effectively prevent dust in the air from falling onto the rotating brush 11, keeping the rotating brush 11 clean and extending its service life. Furthermore, the detachable connection between the cover 35 and the chamber 3 allows the user to easily open the top of the chamber 3, which is convenient for cleaning and replacing the rotating brush 11 or other structures. In case of malfunction, it is also convenient for maintenance and repair, thus improving the applicability of the cleaning chamber.

[0047] To better ensure the cleanliness of the interior of the chamber 3, a dust collection ring 36 is provided inside the chamber 3. The dust collection ring 36 is located below the rotating brush 11, and the bottom end of the dust collection ring 36 is connected to the cyclone chamber 21.

[0048] The rotating brush 11 and the cyclone chamber 21 are connected by the dust collection ring 36. The dust and hair that the rotating brush 11 cleans and falls off the air inlet 41 fall directly into the cyclone chamber 21 through the dust collection ring 36 under the action of gravity. Then, the dust and hair that fell off are collected into the dust collection box 31 through the cyclone chamber 21. This prevents the dust and hair cleaned by the rotating brush 11 from falling into other spaces inside the chamber 3, thus ensuring the cleanliness of the inside of the chamber 3.

[0049] It should also be mentioned that the dust collection ring 36 gradually narrows from top to bottom (the direction described in the embodiment is consistent with the direction indicated in the attached figure), forming a horn-like shape, and connecting the rotating brush 11 and the cyclone chamber 21. When the fan 22 is started, it accelerates the flow rate of dust and air around the rotating brush 11 to the cyclone chamber 21. Because of the horn shape of the dust collection ring, the airflow speed increases as the airflow gradually passes through the narrower channel from the wider channel, further accelerating the flow rate of dust and air at the position of the rotating brush 11 into the cyclone chamber 21, thus improving the efficiency of dust and air separation.

[0050] In addition, the dust collection ring 36 and the rotating brush 11 are arranged concentrically.

[0051] The rotating brush 11 is equipped with a coaxially rotating gear ring 113, which is rotatably connected to the top of the dust collection ring 36. The gear ring 113 and the first motor 12 are driven by a gear 13. The gear ring 113 and the first motor 12 are connected by a gear 13, so that the power of the first motor 12 is transmitted to the gear 13, thereby driving the rotating brush 11 to rotate. This transmission method ensures efficient and stable power transmission, improves the rotation efficiency of the rotating brush 11, ensures stability during long-term use, reduces noise generated during operation, and has a compact structure, which reduces the weight of the entire cleaning chamber, occupies as little space as possible in the chamber, and is more portable, thus optimizing the user experience.

[0052] Specifically, the cyclone chamber 21 has an inlet 211, a dust outlet 212, and an air outlet 213. The inlet 211 of the cyclone chamber 21 is located at the front end of the cyclone chamber 21 and is connected to the bottom end of the dust collection ring 36. The dust outlet 212 of the cyclone chamber 21 is located at the rear end of the cyclone chamber 21 and is connected to the dust collection box 31. The front end of the cyclone chamber 21 is provided with a riser pipe 214. The rear end of the riser pipe 214 extends into the cyclone chamber 21 and blocks the inlet 211. The air outlet 213 passes through the riser pipe 214 and is connected to the outlet of the dust removal duct 32.

[0053] As described above, the inlet 211 of the cyclone chamber 21 is connected to the bottom end of the dust collection ring 36. During the cleaning of the air inlet 41 by the rotating brush 11, the dust falling off is drawn into the cyclone chamber 21 through the inlet 211 by the dust collection ring 36, preventing the dust from falling into other spaces inside the chamber 3. The dust outlet 212 is located at the rear end of the cyclone chamber 21 and is connected to the dust collection box 31, so that the airflow carrying dust can only be thrown into the dust collection box 31 after sufficient dust-air separation in the cyclone chamber 21. The air riser 214 placed at the front end of the cyclone chamber 21 extends into the cyclone chamber 21 and blocks the inlet 211, so that only the clean airflow after sufficient dust-air separation can be blown out from the outlet of the dust removal duct 32 through the air riser 214, preventing the airflow carrying dust from being blown into the outside air when dust enters the cyclone chamber 21 from the inlet 211, thereby achieving a good dust-air separation effect.

[0054] In addition, the dust collection box 31 is detachably connected to one side of the chamber 3, making it convenient for users to remove the dust collection box 31 from the chamber 3 in order to empty the dust and hair inside the dust collection box 31. The dust collection box 31 is provided with a handle 311 for easy disassembly and assembly, so as to ensure that users can easily grasp and operate it when they need to remove the dust collection box 31 from the chamber 3.

[0055] Furthermore, the dust collection box 31 is provided with a dust collection port, and the chamber body 3 is provided with a connecting through hole 14 that connects the dust collection port and the dust outlet 212. The dust collection port corresponds to the dust outlet 212 of the cyclone chamber 21, and a silicone sealing gasket 37 is provided between the dust collection port and the dust outlet 212 to ensure a tight fit between the two.

[0056] To ensure that the dust collection box 31 can be stably installed in the chamber body 3 during cleaning and placement, two opposing limiting ribs 38 are provided in the space between the chamber body 3 and the dust collection box 31. Similarly, two limiting grooves 313 are provided on the dust collection box 31 at the opposite positions. When the dust collection box 31 is installed in the chamber body 3, the limiting grooves 313 can slide into the chamber body 3 along the limiting ribs 38 until the dust collection box 31 is embedded in the chamber body 3. This structural fit not only fixes the dust collection box 31 to the chamber body 3, but also improves the alignment accuracy between the dust collection port and the dust outlet 212, allowing for a tighter fit between the two.

[0057] Based on the above, a connecting pipe 215 is provided between the front end of the riser pipe 214 and the outlet of the dust removal duct 32. The fan 22 is fixed inside the connecting pipe 215. The clean airflow after dust-air separation in the cyclone chamber 21 is blown through the front end of the riser pipe 214 to the outlet of the dust removal duct 32 under the drive of the fan 22. The outlet of the dust removal duct 32 is annular. By setting the connecting pipe 215 between the two, the clean airflow can be directly blown out through the outlet of the dust removal channel under the guidance of the connecting pipe 215, avoiding the clean airflow lacking guidance and returning to the cyclone chamber 21 to cause turbulence, which would reduce the dust-air separation efficiency. The connecting pipe 215 can also fix the fan 22, so that the fan 22 is firmly installed on the airflow path, ensuring the stable operation of the fan 22.

[0058] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
