Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of vehicle-mounted device, specifically relates to a visual vehicle-mounted circulating drying device. BACKGROUND

[0002] In the automotive industry, the presence of moisture can cause corrosion of internal components of the system, directly affecting the reliability and safety performance of the vehicle. With the advancement of technology and the rising demand for higher vehicle durability in the market, solutions that can efficiently remove moisture and extend the life of automotive components are increasingly valued. Therefore, designing a vehicle drying tank with more excellent drying performance has become one of the key driving forces in this field of research and development.

[0003] Traditional vehicle-mounted drying devices usually adopt an opaque shell design, which makes it impossible for users to visually observe the status of the internal drying agent. Due to the lack of effective monitoring means, users have difficulty in accurately determining whether the drying agent has failed and whether it needs to be replaced or regenerated. In this case, users may take conservative measures such as premature replacement due to uncertainty about the status of the drying agent. This not only increases the user's maintenance cost, but also may lead to overuse of the drying agent, resulting in resource waste. On the other hand, if the user fails to timely discover that the drying agent has failed, continued use of the expired drying agent will seriously affect the drying effect, leading to an increase in the humidity of the air inside the vehicle, which may cause electronic equipment failure, mold growth, and other problems, thereby affecting the comfort and safety of the vehicle. Therefore, this design flaw of traditional vehicle-mounted drying devices not only brings inconvenience to users, but also may have a negative impact on the performance of the vehicle and the health of users.

[0006] The utility model discloses a visual vehicle-mounted circulating drying device, which is filled with drying agent in the drying device, and the drying device comprises a shell, an air inlet end, an air outlet end and a heating element.

[0007] The drying agent is a moisture-absorbing color-changing drying agent, the shell is made of transparent or translucent material, the air inlet end and the air outlet end are arranged at two ends of the shell respectively, the heating element is fixed in the shell, and the heating element and the drying agent are in contact with each other.

[0008] Further, the air outlet end is connected to a three-way valve, and the three-way valve is connected to the air outlet pipe I and the air outlet pipe II.

[0009] Further, the air outlet pipe I is in communication with the outside air of the automobile, and the air outlet pipe II is in communication with the air inlet of the automobile mechanical equipment requiring dry air.

[0010] Further, the air outlet pipe II is in communication with the air inlet of the automobile air tank.

[0011] Further, the desiccant includes any one of blue silica gel desiccant, cobalt-free orange silica gel desiccant, and cobalt-free blue silica gel desiccant. The desiccant changes color after absorbing moisture, and through the transparent desiccant device shell and the visual color-changing desiccant, the use of the desiccant device can be observed in real time, and replacement or heating can be performed in time.

[0012] Further, the shell is made of transparent or translucent heat-resistant plastic material, including any one of PSU, PEI, PES, and PC. The desiccant device shell is first transparent or translucent, used to observe the color change of the desiccant, and second, the desiccant device shell is heat-resistant and high-temperature-resistant to prevent the shell from deforming during the heating recovery process of the desiccant.

[0013] Further, the heating element is arranged along the center axis of the shell as a symmetry axis.

[0014] Further, the temperature of the heating element for heating the desiccant is 80-90℃, and the time is 10-15min. The heating time required for the desiccant is short, saving the cost of recycling the desiccant.

[0015] The working voltage of the heating element is 12V, and the power is 80-120W.

[0016] Further, the heating element is a heating film. The heating film is a kind of heating material, which has the characteristics of fast heating, uniform heating, high temperature resistance, etc. The heating film contains conductive materials inside. When powered on, the current passing through these materials will generate heat. The heating film generates heat while radiating infrared rays outward. This infrared ray can be absorbed by objects and converted into heat energy, thereby heating the desiccant.

[0017] Further, the heating film surface has a channel through which water vapor can pass, for discharging the water vapor generated by the heating of the desiccant between the two sides of the heating film.

[0018] Further, a heating film bracket is arranged inside the shell, and the two ends of the heating film bracket are fixed to the inner side of the shell, and the heating film is fixed to the heating film bracket.

[0019] Further, the heating film is fixed to the heating film bracket by adhesion or clamping.

[0020] Further, the heating film is cut into a suitable shape and then placed inside the heating film support to form a cylindrical heating film.

[0021] Further, the heating element is electrically connected with the electrode device, and the electrode device is arranged outside the shell.

[0022] Further, the electrode device is connected with any one of a cigarette lighter of a vehicle, a 12V interface of a trunk and a 12V power supply in the vehicle, and a control voltage of the electrode device is 12V, which is matched with a voltage of the vehicle.

[0023] Further, when the drying device operates and the heating element does not start heating, the three-way valve is communicated with the air outlet pipe II.

[0024] When the drying agent is saturated with moisture and the heating element heats the drying agent, the three-way valve is communicated with the air outlet pipe I.

[0025] The humid air flows through the color-changing drying agent and then output dry air. In the process of absorbing moisture, the color-changing drying agent changes color with the increase of the amount of absorbed moisture, so that the user can intuitively know the use of the drying agent. However, with the increase of time, the adsorption capacity of the material will gradually saturate, and the rate will gradually decrease. In order to ensure that the device is always in the best working condition, the shell is made of transparent or translucent material, and the color-changing drying agent is combined to realize the visualization of the state of the drying agent. When the color of the color-changing drying agent changes to a certain degree, the heating element is used to heat the drying agent to restore the adsorption performance and capacity of the drying agent to the moisture in the air entering the drying device. By using the principle that the adsorption capacity of the adsorption material decreases with the increase of temperature, and introducing air in the process, the moisture stored in the material is discharged to the atmosphere to realize the partial regeneration of the drying agent. The drying device can continuously use the drying medium to reduce resource waste.

[0026] Compared with the prior art, the utility model has the following advantages:

[0027] 1. This utility model uses a transparent or semi-transparent material for the shell of the drying device and a color-changing desiccant. During the moisture absorption process, the color of the desiccant changes as the amount of moisture absorbed increases. Users can observe the desiccant's usage at any time during the use of the drying device, judge the degree of dryness of the drying device, and more scientifically determine when to replace or regenerate it. Furthermore, through the reminders and judgments of the visual device, users can reasonably control the frequency of replacement or regeneration, reducing resource waste.

[0028] 2. This utility model incorporates a heating element in the drying device. The heating element is used to heat the desiccant after it has absorbed too much moisture. After the desiccant is re-dried, it can be reused, forming a recyclable drying device. The desiccant heating and regeneration ensures that the device is always in optimal working condition. Furthermore, the desiccant is a color-changing and recyclable desiccant. The humid air after drying is discharged from the drying device without affecting the drying effect of the device, saving costs and responding to environmental protection policies.

[0029] 3. This utility model fixes the heating element on the heating film support, making the position of the heating element clear and the area that can be heated clear. This avoids the uneven heating caused by stacked and inverted heating elements, which may lead to the danger of overheating. The heating film has a short heating time, low energy consumption, no noise, and a thin volume. Compared with traditional PTC, it does not occupy the space of the desiccant and has a wide heating coverage and high uniformity.

[0030] 4. The heating element in the drying device of this utility model is connected to the electrode device set on the outside of the shell. The control voltage of the electrode device is 12V, which is compatible with the vehicle end voltage and is suitable for drying inside the vehicle. It has strong versatility, and the visual feedback allows users to clearly see the usage status of the device, which improves user trust and user experience. Attached Figure Description
