Description

Technical Field

[0001] The present invention relates to an electric mosquito-repellent incense device. Background Art

[0002] An electric mosquito-repellent incense device is a common mosquito-repellent tool, which mainly uses the capillary principle to continuously heat and release insecticide substances through a heating element. The mosquito-repellent liquid can be used continuously for a long time. However, as the use time increases, the mosquito-repellent liquid continuously decreases, making it difficult for the volatilization rod to effectively absorb the mosquito-repellent liquid. And some users, due to the lack of wall sockets in the bedroom, usually need to insert the mosquito-repellent device on a plug board. This causes the used mosquito-repellent liquid not to fully contact the volatilization rod, affecting the volatilization effect of the mosquito-repellent liquid. At the same time, the existing mosquito-repellent devices make the mosquito-repellent components cover the bedroom, generally taking 15 - 20 minutes, with low efficiency. And when the mosquito-repellent device is inserted on the wall switch panel, after long-term use, it will cause some wall materials to be colored, affecting the appearance and being not conducive to improving the user experience, thus affecting the customer's choice of products and the economic effect of the enterprise. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides an electric mosquito-repellent incense device, which has a simple structure and reasonable layout, ensures the absorption of the mosquito-repellent liquid, improves the volatilization efficiency of the mosquito-repellent device, and makes the distribution of the mosquito-repellent components more reasonable, having a good use effect.

[0004] To achieve the above object, the present invention provides an electric mosquito-repellent incense device, including a bottle base and a liquid storage tank. A volatilization port is provided on the bottle base. An installation table is circumferentially arranged around the volatilization port in the bottle base. A heating component is arranged on the installation table. A mating port is provided on the bottle base. A connection port is provided on the liquid storage tank. A connection thread for tightly mating with the mating port is arranged on the outer peripheral wall of the connection port. An installation step is provided at the connection port of the liquid storage tank. A connection seat is rotatably arranged on the installation step. A siphon rod is connected to the connection seat. An exposure window for operating the rotation of the bottle base is provided at the position of the liquid storage tank corresponding to the connection seat. The free end of the siphon rod extends towards the bottom edge of the liquid storage tank. A shielding cover is movably arranged on one side of the volatilization port on the bottle base.

[0005] The beneficial effects of such a setting are as follows: With such a setting, the design of the movable shield fully takes into account the pain points of users in actual use. During the use of traditional electric mosquito repellent devices, the liquid medicine is likely to adhere to the wall surface after volatilization, which not only affects the wall surface aesthetics but may also cause stains that are difficult to remove after long-term accumulation. However, for the movable shield of this electric mosquito repellent device, its position can be flexibly adjusted. When in use, it can form a barrier between the wall surface and the volatilization port, effectively blocking the volatilized liquid medicine and protecting the wall surface from getting dirty. Further, setting a circulation device in the shield is of great significance. By promoting air circulation, this device can accelerate the diffusion of the mosquito repellent gas formed by the volatilization of the mosquito repellent liquid, making the mosquito repellent range wider and the effect more uniform. For example, when used in a bedroom, the circulation device can quickly cover the entire space with the mosquito repellent gas, avoiding the situation where the mosquito repellent effect is poor in some local areas due to poor air circulation. In the case of a traditional mosquito repellent device in a lying state, the siphon tube is likely to separate from the liquid medicine, resulting in abnormal operation. In this design, the free end of the siphon rod extends towards the bottom edge of the liquid storage tank, and the liquid storage tank is rotatably connected to the connecting seat. When the mosquito repellent device lies horizontally, the user can operate the connecting seat to rotate through the exposed window of the liquid storage tank, easily adjusting the position of the siphon rod to ensure that it is always immersed in the liquid medicine, guaranteeing continuous liquid supply. This design is especially suitable for diverse usage scenarios. For example, when transporting the mosquito repellent device in a suitcase during travel or placing it in an unconventional posture in a narrow space for use, it can work stably, greatly expanding the applicable range of the product. Compared with traditional mosquito repellent devices, it has higher practicality and adaptability.

[0006] As a further setting of the present invention, an installation groove is provided on one side of the volatilization port on the bottle base. An installation seat is swingably arranged in the installation groove. The shield is arranged on the installation seat. A driving motor is arranged in the bottle base. A contact cam is connected to the output shaft of the driving motor, and the contact cam abuts against the bottom surface of the installation seat.

[0007] The beneficial effects of such a setting are as follows: With such a setting, this design that cooperates through the installation groove, swingable installation seat and the driving mechanism endows the shield with flexible adjustment ability. During actual use, the user can easily control the swing of the installation seat through the driving mechanism according to requirements such as the wall distance and space layout, accurately adjusting the position of the shield to ensure that the protective distance between the volatilization port and the wall surface is just right. Whether it is installed vertically, obliquely, or used in a narrow corner, it can effectively prevent the liquid medicine from staining the wall surface. In addition, the addition of the driving mechanism realizes the automation and convenience of the shield adjustment.

[0008] As a further setting of the present invention, an arc-shaped groove is provided on the installation seat. An installation frame is slidably arranged in the arc-shaped groove. A fan is swingably connected to the installation frame.

[0009] The beneficial effects of such a setting are as follows: By setting up a slidable and adjustable fan structure on the mounting base in this way, the diffusion efficiency of the mosquito repellent gas is greatly improved. Through the sliding fit between the arc-shaped groove and the mounting frame, the fan can flexibly adjust its position and angle to adapt to the requirements of different usage scenarios. When the fan swings, it can stir the air at multiple angles, break the static distribution of the gas after the liquid medicine volatilizes, and accelerate its flow and diffusion in the space. In a relatively enclosed environment such as a bedroom, the fan can quickly deliver the mosquito repellent components to every corner to ensure that there is no dead angle for mosquito repellent; in an open space such as a living room, flexibly adjusting the fan angle can expand the mosquito repellent range. At the same time, this design does not affect the protective function of the shield on the wall, achieving a dual optimization of the protective and diffusion effects, and creating a more efficient and comfortable mosquito repellent environment for users.

[0010] As a further setting of the present invention, a retaining edge for shielding the mounting groove is provided at the edge position of the bottom surface of the mounting base.

[0011] The beneficial effects of such a setting are as follows: In the daily use process, dust, hair and other small dirt are likely to enter the device through the gaps of the mounting groove, which may affect the normal operation of components such as the driving mechanism and the fan. The presence of the retaining edge can closely fit the surface of the bottle seat, completely shield the gap at the edge of the mounting groove, and block the intrusion path of external dirt. This not only effectively reduces the risk of component failures caused by foreign object accumulation inside, but also reduces the frequency of user cleaning and maintenance, extends the service life of the product, and at the same time ensures the stability and continuity of the mosquito repellent effect.

[0012] As a further setting of the present invention, a locking groove is provided on the bottom surface of the arc-shaped groove, the inner wall of the locking groove is roughened, and telescopic locking mechanisms for being inserted into the locking groove are provided on both sides of the mounting frame corresponding to the locking groove.

[0013] The beneficial effects of such a setting are as follows: This setting provides a reliable positioning guarantee for the fan position adjustment. When the mounting frame slides to a suitable position in the arc-shaped groove, a telescopic locking mechanism similar to a bolt lock pin automatically pops out and is inserted into the locking groove with a rough inner wall. By using the dual effects of friction and mechanical engagement, the fan is firmly fixed to prevent position deviation caused by factors such as vibration during use. The positioning process is very convenient. The user only needs to push the mounting frame with one hand, and the locking mechanism can complete automatic locking; if the position and angle need to be adjusted, gently press the locking mechanism to retract it, and the fan can be flexibly moved. Whether it is vertically installed, inclined, or in response to different space layouts, this structure can ensure that the fan is always in the best working position, greatly improving the operation convenience and use stability of the product while ensuring the diffusion efficiency of the mosquito repellent gas.

[0014] As a further arrangement of the present invention, the telescopic locking mechanism includes a front tooth component, a rear tooth component, and a guide rail provided on the inner wall of the mounting bracket. The front tooth component, the rear tooth component, and the guide rail form a connection and cooperation that allows them to move back and forth relative to the mounting bracket but prohibits them from rotating relative to the mounting bracket. Guide grooves for sliding cooperation with the guide rail are respectively provided on the circumferences of the front tooth component and the rear tooth component. One end of the front tooth component away from the rear tooth component is connected to a locking pin that is used to abut against or retract into the mounting bracket. A spring is sleeved on the outer wall of the locking pin, and the spring abuts between the mounting bracket and the front tooth component. An operating rod for pressing operation is provided at one end of the rear tooth component away from the front tooth component.

[0015] The beneficial effects of such an arrangement are as follows: With such an arrangement, the telescopic locking mechanism with this pressing structure greatly improves the convenience of user operation and the usage experience. When the position of the fan needs to be adjusted, the user only needs to gently press the operating rod on the rear tooth component, and the rear tooth component will drive the front tooth component to slide backward along the guide rail, compressing the spring and at the same time retracting the locking pin from the locking groove. At this time, the mounting bracket can slide freely in the arc-shaped groove. After adjusting to the ideal position, release the operating rod. Under the action of the spring force, the front tooth component drives the locking pin to quickly pop out and precisely engage into the rough surface on the inner wall of the locking groove, and the fan is firmly locked by the dual actions of mechanical engagement and frictional resistance.

[0016] As a further arrangement of the present invention, the siphon rod is arranged in an L shape.

[0017] The beneficial effects of such an arrangement are as follows: With such an arrangement, the siphon rod is designed in an L shape, which provides a guarantee for the efficient extraction of the mosquito repellent liquid from the structure. Its vertical part is convenient for firmly connecting with the bottle seat, and the horizontally extending bent section can be closest to the bottom of the liquid storage tank to the greatest extent. When the electric mosquito repellent device is in the normal upright state, the horizontal section can directly extract the liquid medicine at the bottom; in the case of unconventional placements such as lying horizontally or tilting, by rotating the bottle seat, the horizontal section can still fit the bottom of the tank, ensuring that it is always immersed in the liquid medicine and avoiding the interruption of supply due to position changes.

[0018] As a further arrangement of the present invention, the siphon rod includes a connecting part and a working part arranged obliquely. The connecting part is connected to the connecting seat, one end of the working part is connected to the connecting part, and the other end abuts against the edge of the bottom surface of the liquid storage tank.

[0019] The beneficial effects of such a setting are as follows: With such a setting, the vertical connecting part ensures the stable installation of the siphon rod on the bottle base, while the inclined working part always fits the bottom edge of the liquid storage tank, forming an efficient siphon path. When the electric mosquito repellent device is placed at any angle, the end of the working part can contact the liquid medicine to the maximum extent, and the gravity and siphon principle are utilized to ensure the continuous delivery of the liquid medicine. Even when the stock of the mosquito repellent liquid is small, the inclined design can guide the residual liquid medicine to converge towards the working part, avoiding the failure of absorption caused by the deposition of the liquid medicine, and significantly improving the battery life and use stability of the product.

The beneficial effects of such a setting are as follows: With such a setting, the design of the movable shielding cover 31 fully considers the pain points of users in actual use. During the use of traditional electric mosquito repellent devices, the liquid medicine is prone to adhere to the wall surface after volatilization, which not only affects the beauty of the wall surface, but may also cause stains that are difficult to remove after long-term accumulation. However, for the movable shielding cover 31 of this electric mosquito repellent device, the position can be flexibly adjusted. When in use, it can form a barrier between the wall surface and the volatilization port 11, effectively blocking the volatilized liquid medicine and protecting the cleanliness of the wall surface. Further, setting a circulation device in the shielding cover 31 is of great significance. This device can accelerate the diffusion of the mosquito repellent gas formed by the volatilization of the mosquito repellent liquid by promoting air circulation, making the mosquito repellent range wider and the effect more uniform. For example, when used in a bedroom, the circulation device can quickly cover the entire space with the mosquito repellent gas, avoiding the situation where the mosquito repellent effect is poor in some local areas due to poor air circulation. In the traditional mosquito repellent device in the horizontal lying state, the siphon tube is prone to separating from the liquid medicine, resulting in abnormal operation.

When the mosquito repellent device is in the horizontal lying state, the user can operate the connection seat 7 to rotate through the exposure window of the liquid storage tank 2, easily adjust the position of the siphon rod 71, and ensure that it is always immersed in the liquid medicine to ensure continuous liquid supply. This design is particularly suitable for diverse usage scenarios. For example, when transporting the mosquito repellent device in a suitcase during travel, or placing it in an unconventional posture in a narrow space for use, it can work stably, greatly expanding the applicable range of the product. Compared with traditional mosquito repellent devices, it has higher practicality and adaptability.

A contact cam 13 is connected to the output shaft of the driving motor 12. The contact cam 13 abuts against the bottom surface of the installation seat 3. The beneficial effect of such a setting is as follows: With such a setting, this design that combines the installation groove, the swingable installation seat 3 and the driving mechanism endows the shielding cover 31 with flexible adjustment ability. During actual use, users can easily control the swing of the installation seat 3 through the driving mechanism according to requirements such as the wall distance and space layout, and accurately adjust the position of the shielding cover 31 to ensure that the protective distance between the volatilization port 11 and the wall is just right. Whether it is installed vertically, obliquely, or used in a narrow corner, it can effectively prevent the liquid medicine from contaminating the wall. In addition, the addition of the driving mechanism realizes the automation and convenience of the adjustment of the shielding cover 31.

[0023] As a further setting of this embodiment, an arc-shaped groove 32 is provided on the installation seat 3. An installation frame 4 is slidably arranged in the arc-shaped groove 32. A fan 41 is swingably connected to the installation frame 4. The beneficial effect of such a setting is as follows: With such a setting, the structure of the fan 41 that can be slidably adjusted is added to the installation seat 3, greatly improving the diffusion efficiency of the mosquito repellent gas. Through the sliding cooperation of the arc-shaped groove 32 and the installation frame 4, the fan 41 can flexibly adjust its position and angle to adapt to the needs of different usage scenarios. When the fan 41 swings, it can stir the air at multiple angles, break the static distribution of the gas after the liquid medicine volatilizes, and accelerate its flow and diffusion in the space. In a relatively enclosed environment such as a bedroom, the fan 41 can quickly deliver the mosquito repellent components to each corner to ensure there is no dead corner for mosquito repellent; in an open space such as a living room, flexibly adjusting the angle of the fan 41 can expand the mosquito repellent range.

[0024] As a further setting of this embodiment, a retaining edge 33 for shielding the installation groove is provided at the edge position of the bottom surface of the installation seat 3. The beneficial effect of such a setting is as follows: During daily use, small dirt such as dust and hair is likely to enter the device interior through the gaps in the installation groove, which may affect the normal operation of components such as the driving mechanism and the fan 41. The presence of the retaining edge 33 can closely fit the surface of the bottle base 1, completely shielding the gaps at the edge of the installation groove and blocking the intrusion path of external dirt. This not only effectively reduces the risk of component failures caused by foreign object accumulation inside, but also reduces the frequency of cleaning and maintenance by users, extends the product service life, and at the same time ensures the stability and continuity of the mosquito repellent effect.

[0025] As a further setting of this embodiment, a locking groove 34 is provided on the bottom surface of the arc-shaped groove 32. The inner wall of the locking groove 34 is roughened. Corresponding to the locking groove 34 on both sides of the mounting frame 4, there is a telescopic locking mechanism for being inserted into the locking groove 34. The beneficial effect of such a setting is as follows: With such a setting, a reliable positioning guarantee is provided for the position adjustment of the fan 41. After the mounting frame 4 slides to a proper position in the arc-shaped groove 32, a telescopic locking mechanism similar to the bolt lock pin 51 automatically pops out and is inserted into the locking groove 34 with a rough inner wall. By the dual actions of friction and mechanical engagement, the fan 41 is firmly fixed, avoiding position deviation caused by factors such as vibration during use. The positioning process is very convenient. The user only needs to push the mounting frame 4 with one hand, and the locking mechanism can complete automatic locking. If the position angle needs to be adjusted, gently press the locking mechanism to retract it, and then the fan 41 can be flexibly moved. Whether it is vertically installed, inclined, or in response to different spatial layouts, this structure can ensure that the fan 41 is always in the best working position, greatly improving the operation convenience and use stability of the product while ensuring the diffusion efficiency of the mosquito repellent gas.

[0026] As a further setting of this embodiment, the telescopic locking mechanism includes a front tooth component 5, a rear tooth component 6, and a guide rail provided on the inner wall of the mounting frame 4. The front tooth component 5, the rear tooth component 6, and the guide rail form a connection and cooperation that allows them to move back and forth relative to the mounting frame 4 but prohibits them from rotating relative to the mounting frame 4. Guide grooves for sliding fit with the guide rail are respectively provided on the circumferences of the front tooth component 5 and the rear tooth component 6.
