Description

Technical Field

[0001] This utility model relates to the field of razor cleaning technology, and in particular to a cleaning device. Background Technology

[0002] As an essential tool for men's daily grooming, the cleaning and maintenance of razors directly impacts user experience and hygiene. With technological advancements, razor cleaning devices with automatic cleaning functions have become increasingly common. These devices typically remove residual beard debris, dander, and bacteria from the razor head through a circulating cleaning solution. After cleaning, a certain amount of cleaning solution remains on the razor. To accelerate drying, current technology generally employs a fan design to increase airflow. Some cleaning devices have an internal fan that uses forced convection to increase airflow speed over the razor surface, thereby accelerating moisture evaporation. However, ensuring pressure balance between the inside and outside of the device is crucial for fan operation. Therefore, current technology typically incorporates ventilation holes on the outer casing of the cleaning device corresponding to the fan location to facilitate pressure exchange.

[0003] However, the gaps created by adding additional ventilation holes expose these holes directly to the external environment. During daily use, dust, hair, and other debris can easily enter the cleaning equipment through these gaps, contaminating it. Furthermore, to meet air pressure balance requirements, the ventilation holes need a certain area, necessitating multiple openings in the outer casing. This weakens the overall structural strength of the casing, and especially after prolonged use, frequent air pressure changes may accelerate material fatigue, leading to cracking or deformation. In addition, the presence of these holes disrupts the integrity of the casing, affecting the product's simplicity and aesthetics, which does not meet modern consumers' demands for sophisticated home appliances. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a cleaning device that can solve the problems of internal pollution and low overall integrity of the cleaning device caused by setting ventilation holes to balance the internal and external air pressure of the cleaning device.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A cleaning device, comprising:

[0007] The housing is provided with a cleaning tank for placing and cleaning electrical equipment and an airflow gap for exchanging airflow between the inside and outside of the housing;

[0008] A fan has a first air outlet and a second air outlet. The first air outlet is connected to the cleaning tank, and the second air outlet is located inside the housing. The second air outlet is connected to the outside of the housing through the airflow gap of the housing.

[0009] Furthermore, it also includes a heating element, which is disposed on one side of the cleaning tank, or the heating element is disposed between the fan and the first air outlet.

[0010] By adopting the above solution, the heating element can increase the temperature of the air inside the cleaning tank or entering the cleaning tank through the first air vent, thereby accelerating the evaporation of moisture near the parts of the electrical equipment being cleaned within the cleaning tank. This significantly shortens the drying time and improves the overall efficiency of cleaning and drying.

[0011] Furthermore, the outer casing includes an upper shell and a base, the upper shell and the base are separately disposed, one end of the upper shell is provided with an opening, the base is disposed at the opening, and the gap between the opening and the base constitutes an airflow gap.

[0012] By adopting the above design, which divides the outer casing into an upper shell and a base, the assembly, maintenance, and replacement of internal components such as the cleaning fluid container of the cleaning equipment are facilitated. The fit gap between the opening and the base naturally forms an airflow channel, which not only meets the needs of air circulation but also simplifies the product manufacturing process.

[0013] Furthermore, the cleaning tank and the outer shell are separately disposed, the outer shell is fitted around the outer periphery of the cleaning tank, and the outer shell overlaps with the upper edge of the cleaning tank, and the gap between the outer shell and the cleaning tank constitutes an airflow gap.

[0014] By adopting the above solution, the separate design of the cleaning tank and the outer shell not only facilitates manufacturing, but also simplifies the subsequent maintenance and replacement process. Correspondingly, the airflow gap formed between the outer shell and the cleaning tank can effectively promote air circulation, ensure smooth airflow exchange between the inside and outside of the cleaning equipment, help accelerate the drying process, and improve efficiency.

[0015] Furthermore, it also includes a light guide plate and a lamp plate. The light guide plate is disposed between the cleaning tank and the outer shell. One side of the light guide plate overlaps with the edge of the cleaning tank, and the other side overlaps with the outer shell. The gap between the light guide plate and the cleaning tank and the gap between the light guide plate and the outer shell both constitute airflow gaps. The light-emitting side of the lamp plate is arranged facing the light guide plate.

[0016] By adopting the above solution, a light guide plate is set between the cleaning tank and the outer shell, with one side of the light guide plate overlapping the edge of the cleaning tank and the other side overlapping the outer shell. The gap between the light guide plate and the cleaning tank and the outer shell is used as an airflow gap. At the same time, the light-emitting side of the lamp panel is directed towards the light guide plate. This design not only enhances the air circulation efficiency and improves the drying effect inside the cleaning equipment, but also makes the lighting more uniform by taking advantage of the good light guiding performance of the light guide plate, thus improving the user experience.

[0017] Furthermore, the outer casing is also provided with a structural plate, and the structural plate has a first ventilation hole in the direction in which the second air vent faces, so that the airflow affected by the fan flows through the structural plate.

[0018] By adopting the above solution, a structural plate is set inside the outer shell and a first ventilation hole is opened on it in the direction of the second air outlet, so that the airflow generated by the fan can pass smoothly through the structural plate. This design not only optimizes the airflow path inside the cleaning equipment, but also improves the air circulation efficiency and drying effect.

[0019] Furthermore, the upper edge of the cleaning tank is provided with a flange facing away from the center of the cleaning tank, the light panel is mounted on the flange, the flange is provided with a second ventilation hole, and the light panel is provided with a third ventilation hole. The second ventilation hole and the third ventilation hole are arranged correspondingly to allow the airflow affected by the fan to flow through the flange and the light panel.

[0020] By adopting the above solution, a flange is set on the upper edge of the cleaning tank and the light panel is assembled on the flange. At the same time, corresponding second and third ventilation holes are set on the flange and the light panel respectively, so that the airflow generated by the fan can pass through smoothly. This structure not only optimizes the airflow path and improves the airflow efficiency and drying effect, but also enhances the structural strength of the edge of the cleaning tank and prevents deformation.

[0021] Furthermore, the light guide plate is provided with a fourth ventilation hole, which corresponds to the third ventilation hole.

[0022] By adopting the above solution, a fourth ventilation hole corresponding to the third ventilation hole on the lamp plate is set on the light guide plate, ensuring smooth airflow and improving drying efficiency.

[0023] Furthermore, the light guide plate is provided with a first buckle, the flange is provided with a second buckle, and the lamp plate is provided with a clearance hole. The first buckle and the second buckle pass through the clearance hole and engage. When the first buckle and the second buckle engage, the second ventilation hole, the third ventilation hole and the fourth ventilation hole are in corresponding positions.

[0024] By adopting the above solution, and using a snap-fit ​​structure instead of traditional screws or glue for fixing, the assembly of the light guide plate, flange, and lamp panel is made simpler and faster, reducing installation time and complexity. The first and second snap-fits pass through the clearance holes on the lamp panel to achieve precise engagement, ensuring that the second ventilation hole (flange), third ventilation hole (lamp panel), and fourth ventilation hole (light guide plate) can be accurately aligned, ensuring that airflow can pass smoothly through each component and optimizing air circulation efficiency.

[0025] Furthermore, it also includes a function panel, which is embedded in the housing, and the gap between the edge of the function panel and the housing forms an airflow gap.

[0026] By adopting the above solution and utilizing the gap between the edge of the functional panel and the outer casing to form an airflow channel, airflow can be effectively promoted, ensuring smoother airflow exchange between the inside and outside environment of the cleaning equipment. This helps improve the ventilation efficiency inside the equipment and further enhances the drying effect.

[0027] In summary, the cleaning equipment provided by this utility model has the following technical effects:

[0028] 1. This utility model uses an airflow gap instead of a traditional ventilation hole. Airflow exchange is achieved through the gap between the outer shell and components such as the cleaning tank, light guide plate, and functional panel, which prevents foreign objects from directly entering the interior and significantly improves the cleanliness and hygiene safety of the device.

[0029] 2. The outer casing requires no additional openings, resulting in a more robust overall structure, extended service life, and reduced failure rate due to material fatigue.

[0030] 3. The outer casing does not require additional openings, resulting in a better overall integrity of the cleaning equipment and a more complete outer surface, thus making the cleaning equipment more aesthetically pleasing. Attached Figure Description

[0041] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described and discussed below with reference to the accompanying drawings. Obviously, what is described here is only a part of the examples of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the protection scope of this invention.

[0042] To facilitate understanding of the embodiments of this utility model, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this utility model.

[0043] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0045] See Figures 1-9This utility model discloses a cleaning device, including a housing 1 and a fan 2. The housing 1 is provided with a cleaning tank 11 for placing and cleaning electrical equipment and an airflow gap 3 for exchanging airflow inside and outside the housing 1. The fan 2 has a first air outlet 21 and a second air outlet 22. The first air outlet 21 is connected to the cleaning tank 11 of the cleaning device, and the second air outlet 22 is located inside the housing 1 and is connected to the outside of the housing 1 through the airflow gap 3 of the housing 1.

[0046] Specifically, the outer casing 1 is provided with a cleaning tank 11 and an airflow gap 3. The cleaning tank 11 is used to place and clean electrical equipment (such as razors). The airflow gap 3 replaces the traditional ventilation hole, realizing airflow exchange between the inside and outside of the outer casing 1 and preventing foreign objects from entering the device. The airflow gap 3 can be a splicing seam designed in the multi-segment design of the outer casing 1, or a hole drilled for the installation of other components. The gap between the component and the hole when the corresponding component is assembled in the hole is not limited here. The fan 2 structure has a first air outlet 21 and a second air outlet 22. The first air outlet 21 is connected to the cleaning tank 11, and the second air outlet 22 is located inside the outer casing 1, and the second sealing hole is connected to the airflow gap 3. The airflow exchange between the inside and outside of the outer casing 1 is completed through the airflow gap 3. The first air vent 21 can be either an air inlet or an air outlet, and the second air vent 22 can be either an air inlet or an air outlet. Specifically, whether the fan 2 draws air from the cleaning tank 11 or blows air into the cleaning tank 11, it can accelerate the airflow in the cleaning tank 11. Correspondingly, it can accelerate the airflow at the shaver head and accelerate the drying of the shaver head. Therefore, the specific air intake and air exhaust functions of the first air vent 21 and the second air vent 22 are not limited here.

[0047] See Figures 1-4 As shown, in some embodiments, the outer shell 1 includes an upper shell 12 and a base 13. The upper shell 12 and the base 13 are separately disposed. One end of the upper shell 12 is provided with an opening, and the base 13 is disposed at the opening. The gap between the opening and the base 13 constitutes an airflow gap 3.

[0048] Specifically, the processing, assembly, and maintenance of the cleaning equipment all require disassembly. The cleaning fluid container is typically located inside the outer shell 1 and needs periodic replacement as the cleaning fluid is used. Therefore, the outer shell 1 is divided into a separate upper shell 12 and a base 13. Separating the upper shell 12 and base 13 facilitates the processing, assembly, maintenance, and replacement of the cleaning fluid container. Correspondingly, one end of the upper shell 12 has an opening to facilitate processing, assembly, maintenance, and replacement of the cleaning fluid container. The base 13 is located at the opening, providing a certain degree of sealing. Due to accumulated tolerances and surface roughness, a gap inevitably exists between the opening of the upper shell 12 and the base 13. This gap constitutes the airflow gap 3, used for airflow exchange between the inside and outside of the upper shell 12.

[0049] See Figure 1-3 and Figure 5 As shown, in some embodiments, the cleaning tank 11 and the outer shell 1 are separately disposed, the outer shell 1 is sleeved on the outer periphery of the cleaning tank 11, and the upper edge of the outer shell 1 overlaps with the upper edge of the cleaning tank 11, and the gap between the outer shell 1 and the cleaning tank 11 constitutes the airflow gap 3.

[0050] Specifically, since the cleaning tank 11 is generally installed submerged within the outer casing 1, and the cleaning tank 11 needs to consider the piping setup for the cleaning fluid flow, the stability of electrical equipment within the cleaning tank 11, and the subsequent installation of guide plates, it is generally not chosen to be integrally formed with the outer casing 1. Instead, the outer casing 1 is fitted around the outer periphery of the cleaning tank 11, forming the basic structure of the cleaning tank 11 being submerged within the outer casing 1, and the upper edges of the outer casing 1 and the cleaning tank 11 overlap. The gap between the outer casing 1 and the cleaning tank 11 constitutes the airflow gap 3. Similarly, whether due to cumulative tolerances or surface roughness, there will inevitably be a fitting gap between the cleaning tank 11 and the outer casing 1, which constitutes the airflow gap 3 for the exchange of airflow inside and outside the outer casing 1.

[0051] See Figure 1-3 and Figure 5 As shown, the cleaning equipment further includes a light guide plate 14 and a lamp plate 17. The light guide plate 14 is disposed between the cleaning tank 11 and the outer shell 1. One side of the light guide plate 14 overlaps with the edge of the cleaning tank 11, and the other side overlaps with the outer shell 1. The gap between the light guide plate 14 and the cleaning tank 11 and the gap between the light guide plate 14 and the outer shell 1 both constitute the airflow gap 3. The light-emitting side of the lamp plate 17 is arranged facing the light guide plate 14.

[0052] Specifically, to facilitate the placement of electrical equipment and to ensure the overall stability of the cleaning equipment's center of gravity, the cleaning tank 11 is typically positioned in a prominent central location. Correspondingly, a light guide plate 14 can be placed near the cleaning tank 11, with the light-emitting side of the lamp panel 17 facing the light guide plate 14. This allows the light emitted by the lamp panel 17 to be displayed in a prominent position, easily alerting the user to the cleaning equipment's operating status through lighting information. The light guide plate 14 is made of a light-guiding material, ensuring it does not obstruct the light from passing through it. When the light guide plate 14 is positioned between the cleaning tank 11 and the outer casing 1, one side of the light guide plate 14 overlaps with the edge of the cleaning tank 11, and the other side overlaps with the outer casing 1. The gaps between the light guide plate 14 and the cleaning tank 11, and between the light guide plate 14 and the outer casing 1, both constitute airflow gaps 3. In other words, this structure forms two airflow gaps 3, improving the airflow exchange efficiency between the inside and outside of the outer casing 1.

[0053] See Figure 1-3 and Figure 7 As shown, in some embodiments, the housing 1 is further provided with a structural plate 15, and the structural plate 15 is provided with a first ventilation hole 151 in the direction of the second air outlet 22 so that the airflow affected by the fan 2 flows through the structural plate 15.

[0054] Specifically, in order to facilitate the installation of basic components inside the outer casing 1, an assembly carrier is required for installation. In this embodiment, for the installation of other components, a structural plate 15 is provided inside the outer casing 1 as an assembly carrier. Correspondingly, in order to prevent the installation of the structural plate 15 from affecting the airflow of the fan 2, a first ventilation hole 151 is provided on the structural plate 15 in the direction of the second air outlet 22, so that the airflow affected by the fan 2 flows through the structural plate 15.

[0055] Based on the structure of the outer shell 1 including the separate upper shell 12 and base 13, and the upper shell 12 being separately set from the cleaning tank 11, that is, the upper and lower parts of the upper shell 12 both have airflow gaps 3, so the first ventilation hole 151 is provided on the structural plate 15. Regardless of whether the structural plate 15 is above or below the second air outlet 22, the structural plate 15 will not affect the airflow passing over the structural plate 15.

[0056] See Figure 5 and Figure 7-9 As shown, based on the structure of setting the light guide plate 14, the upper edge of the cleaning tank 11 is provided with a flange 16 in the direction away from the center of the cleaning tank 11, and the lamp plate 17 is set on the flange 16. The flange 16 is provided with a second ventilation hole 161, and the lamp plate 17 is provided with a third ventilation hole 171. The second ventilation hole 161 and the third ventilation hole 171 are provided correspondingly so that the airflow affected by the fan 2 flows through the flange 16 and the lamp plate 17.

[0057] Specifically, the upper edge of the cleaning tank 11 extends away from the center of the cleaning tank 11 to form a flange 16. The flange 16 serves as an edge reinforcement structure for the cleaning tank 11, preventing deformation during use. The flange 16 also serves as a mounting base for the light panel 17, facilitating the integration of lighting or display functions. Correspondingly, the flange 16 may affect gas flow; therefore, a second ventilation hole 161 is provided on the flange 16 to ensure that airflow can freely pass through it. The light panel 17 is mounted on the outside of the flange 16. The light panel 17 can integrate an LED light source to provide internal lighting for the cleaning tank 11, allowing the user to observe the cleaning status.

[0058] Optionally, the size and shape of the second ventilation hole 161 must match the third ventilation hole 171 of the lamp panel 17 to ensure smooth airflow. Multiple second ventilation holes 161 can be provided, and they are evenly distributed along the edge of the flange 16 to avoid localized airflow stagnation. Multiple third ventilation holes 171 can also be provided, distributed along the edge of the lamp panel 17, corresponding one-to-one with the second ventilation holes 161.

[0059] See Figure 7-9 As shown, in some embodiments, the light guide plate 14 is provided with a fourth ventilation hole 141, which corresponds to the third ventilation hole 171.

[0060] Specifically, to ensure the strength of the light guide plate 14, it needs to have a certain cross-sectional area. However, a larger cross-sectional area may interfere with airflow. To address this, the size and shape of the fourth ventilation hole 141 must match the third ventilation hole 171 of the lamp plate 17 to ensure smooth airflow. Optionally, the fourth ventilation hole 141 is distributed along the edge of the light guide plate 14, corresponding one-to-one with the third ventilation hole 171 of the lamp plate 17. This ensures that airflow can pass normally through the flange 16, the lamp plate 17, and the light guide plate 14.

[0061] See Figure 7-9 As shown, in some embodiments, the light guide plate 14 is provided with a first buckle 142, the flange 16 is provided with a second buckle 162, and the lamp plate 17 is provided with a clearance hole 172. The first buckle 142 and the second buckle 162 pass through the clearance hole 172 and engage. When the first buckle 142 and the second buckle 162 engage, the second ventilation hole 161, the third ventilation hole 171 and the fourth ventilation hole 141 are in corresponding positions.

[0062] Specifically, a first latch 142 is provided on one side edge of the light guide plate 14. The first latch 142 is used to engage with a second latch 162 of the flange 16, enabling quick assembly of the light guide plate 14 and the flange 16. A second latch 162 is provided on one side edge of the flange 16. The second latch 162 engages with the first latch 142 of the light guide plate 14, ensuring a tight connection between the light guide plate 14 and the flange 16. The shape of the second latch 162 matches the first latch 142, ensuring that the relative positions of the light guide plate 14 and the flange 16 are fixed. A clearance hole 172 is provided on the lamp plate 17, located on the path of the first latch 142 and the second latch 162. The clearance hole 172 allows the first latch 142 of the light guide plate 14 and the second latch 162 of the flange 16 to pass through the lamp plate 17, achieving engagement. The size of the clearance hole 172 matches the latches, ensuring that the latches will not jam or shift when inserted. The inner diameter of the clearance hole 172 is slightly larger than the maximum outer diameter of the buckle to ensure that the buckle can slide freely. The clearance hole 172 is distributed along the edge of the lamp plate 17 and corresponds to the position of the fourth ventilation hole 141 of the light guide plate 14 and the second ventilation hole 161 of the flange 16.

[0063] Optionally, the first clip 142 and the second clip 162 can be L-shaped, hook-shaped, or elastic tongue-shaped, ensuring a secure and non-detachable connection. The first clip 142 and the second clip 162 can be complementary; for example, if the first clip 142 is hook-shaped, then the second clip 162 can be a corresponding hook or groove shape. The first clip 142 and the second clip 162 can be made of a plastic material (such as ABS or PC) integrally molded with the light guide plate 14, balancing strength and elasticity.

[0064] Align the first latch 142 of the light guide plate 14 with the second latch 162 of the flange 16, and push it towards the lamp panel 17. The first latch 142 of the light guide plate 14 and the second latch 162 of the flange 16 pass through the clearance hole 172 of the lamp panel 17, forming a snap-fit. After the latches are fully engaged, the light guide plate 14, flange 16, and lamp panel 17 form an integral structure without the need for additional screws or glue. The snap-fit ​​structure simplifies the assembly process and reduces the complexity of traditional screw fixing or glue bonding. The components can be disassembled independently for easy cleaning or replacement (such as replacing the light guide plate 14 and lamp panel 17). The shape of the latch matches the size of the clearance hole 172, avoiding component misalignment caused by assembly errors. The fourth ventilation hole 141 (light guide plate 14) and the third ventilation hole 171 (lamp panel 17) automatically align after being snapped together. The second ventilation hole 161 (flange 16) and the third ventilation hole 171 (lamp panel 17) are also aligned due to the snap-fit ​​fixing. Airflow can freely pass through the flange 16, the lamp plate 17 and the light guide plate 14 inside the housing 1.

[0065] See Figure 3 and Figure 6As shown, in some embodiments, the cleaning device further includes a function panel 18, which is embedded in the housing 1, and the gap between the edge of the function panel 18 and the housing 1 forms an airflow gap 3.

[0066] Specifically, since the cleaning device may need to be equipped with a power switch, disassembly switch or control panel, the outer casing 1 needs to be provided with holes for installing the structure. Correspondingly, the function panel 18 is assembled in the hole, and the fitting point between the function panel 18 and the hole will form an airflow gap 3, which facilitates the flow of air inside and outside the outer casing 1 through the airflow gap 3.

[0067] See Figure 3 As shown, in some embodiments, the cleaning device further includes a heating element 4, which is disposed on one side of the cleaning tank 11, or the heating element 4 is disposed between the fan 2 and the first air outlet 21.

[0068] Specifically, the heating element 4 can accelerate the drying of electrical equipment. The heating element 4 is located on one side of the cleaning tank 11, thereby heating the air near the part of the electrical equipment being cleaned in the cleaning tank 11, thereby improving the drying efficiency. The heating element 4 can also be located between the fan 2 and the first air outlet 21, so that the heating element 4 heats the flowing air through the electrical equipment located in the cleaning tank 11, thereby improving the drying efficiency. This is not limited here.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
