Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an air freshener dispensing device. Background Technology

[0002] Air fresheners can eliminate various odors in the air and improve air quality in living and working spaces. However, in most cases, air fresheners are simply placed directly in the room or car, allowing them to evaporate into the air. According to the laws of molecular diffusion, this evaporation method has extremely poor diffusion efficiency, making it difficult to smell the fragrance from a distance. This is especially true in winter when temperatures are low, further reducing the diffusion efficiency and failing to achieve the desired effect.

[0003] Some air freshener dispersing devices rely on a heat source for heating and volatilization, requiring an external power supply. This makes them unsuitable for areas without power sources, such as coffee tables in living rooms or passenger dashboards in cars. Regardless of whether the surrounding environment requires it, they continue to heat as long as the heat source is turned on, continuing to volatilize even when no one is around. This results in ineffective consumption of the air freshener and poses a safety hazard. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides an air freshener dispensing device, which at least partially solves the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model is as follows: An air freshener dispensing device, comprising: The device body has a pad-shaped structure with a concave upper surface. It has a cavity inside for holding air freshener, which can provide limiting support for objects such as water cups and mobile phones, thereby achieving stable placement of the objects and preventing them from sliding or shifting. A filling tube is provided at the center of the upper surface of the device body. The filling tube passes through the upper surface of the device body axially and communicates with the cavity. The upper opening of the filling tube forms a filling port, through which air freshener can be delivered into the cavity. The device body has a skirt extending outward from the upper edge of the main body. The skirt is wavy and the upper surface of the skirt is higher than the recessed area of ​​the upper surface. The device body has a radiating hole that penetrates the cavity on its side wall. The radiating hole is located below the wavy skirt, and the horizontal height of the radiating hole is higher than the height of the filling port. The device body also has an air chamber inside, which is located directly above the cavity and is independent of the cavity. The air chamber is disc-shaped, and the filling tube is non-connected and passes through the center of the air chamber. The side wall of the air chamber is provided with a one-way valve, and an air outlet hose is provided between the air chamber and the cavity. One end of the air outlet hose is connected to the air chamber, and the other end extends into the cavity.

[0006] In a further embodiment, the air cavity is provided with multiple sets of elastic support walls, one end of which is fixedly connected to the bottom wall of the air cavity, and the other end is fixedly connected to the top wall of the air cavity. Multiple sets of elastic support walls are centrally symmetrically distributed inside the air cavity with the axis of the filling tube as the center, and the multiple sets of elastic support walls do not intersect each other.

[0007] In a further embodiment, the upper recessed surface of the device body is uniformly provided with multiple sets of protrusions, the protrusions are arranged in a honeycomb pattern, and the protrusions and the device body are integrally formed.

[0008] In a further embodiment, the lower wall surface of the device body is provided with anti-slip protrusions.

[0009] In a further embodiment, a sealing plug is provided at the filling port, and the sealing plug is configured to match the size of the filling port.

[0010] In a further embodiment, the device body is made of elastic silicone material.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows: The device's cushion-shaped structure allows it to hold objects. The object's weight compresses the air chamber, and the object's heat conduction triggers the release of air freshener. It can accelerate the release of air freshener without any external power source, making it flexible and adaptable to various scenarios such as cars and living rooms. Furthermore, the triggering is related to the use of the object, which can prevent the air freshener from being wasted.

[0012] Air can be delivered from the air chamber into the container through the air outlet hose, impacting the liquid air freshener inside and generating bubbles. The bursting of these bubbles accelerates the evaporation of the air freshener. Meanwhile, the emitting holes are distributed circumferentially along the side wall of the device body and are higher than the filling port, ensuring that the fragrance evenly covers the surrounding space and preventing leakage of air freshener during filling.

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0017] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments 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 the embodiments.

[0018] In winter, when temperatures are low, the diffusion efficiency of air fresheners is also very low, making it difficult to achieve the desired effect. Some air freshener dispersing devices rely on heat sources for heating and evaporation, requiring an external power supply, making them inflexible for areas without power sources, such as coffee tables in living rooms or passenger dashboards in cars. Regardless of whether the surrounding environment requires it, as long as the heat source is turned on, it will continue to heat and evaporate, resulting in ineffective consumption of the air freshener and posing safety hazards.

[0019] Recognizing the above problems, this application proposes and discloses an air freshener dispersing device that can utilize the weight of an object and heat conduction to trigger the dispersal of air freshener, thereby improving dispersal efficiency.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, this disclosure provides an air freshener dispensing device, comprising: The main body of the device 1 is made of elastic silicone material, and its interior has a cavity 2 for holding air freshener; The device body 1 has a pad-shaped structure and the upper surface is recessed. This recessed shape can provide limiting support for objects such as water cups and mobile phones, thereby achieving stable placement of the objects and preventing them from sliding or shifting. A filling tube 3 is provided at the center of the upper surface of the device body 1. The filling tube 3 passes through the upper surface of the device body 1 along the axis and communicates with the cavity 2. The upper opening of the filling tube 3 forms a filling port 4, through which air freshener can be delivered into the cavity 2. The upper edge of the device body 1 is provided with a skirt 5 extending outward. The skirt 5 is wavy, and the height of the upper surface of the skirt 5 is higher than the recessed area of ​​the upper surface. The device body 1 has a radiating hole 6 that penetrates the cavity 2 on its side wall. The radiating hole 6 is located below the wavy skirt 5, and the horizontal height of the radiating hole 6 is higher than the height of the filling port 4. The device body 1 is also provided with an air chamber 7, which is located directly above the cavity 2 and is independent of the cavity 2. The air chamber 7 is arranged in a dish shape, and the filling tube 3 is non-connected and passes through the center of the air chamber 7. The side wall of the air chamber 7 is provided with a one-way valve 8, and an air outlet hose 9 is provided between the air chamber 7 and the cavity 2. One end of the air outlet hose 9 is connected to the air chamber 7, and the other end extends into the cavity 2.

[0021] In this embodiment, since the horizontal height of the emitting hole 6 is higher than the height of the filling port 4, even if the cavity 2 is filled with liquid air freshener, it will not overflow from the emitting hole 6, thus avoiding leakage and pollution during filling. After the cavity 2 is filled, the filling port 4 can be sealed with a sealing cap to prevent the liquid in the cavity 2 from splashing out due to bumps or from ineffective evaporation when not triggered in a vehicle setting.

[0022] When the user places an object in the recessed area on the upper surface of the device body 1, the object's own weight presses down on the upper surface of the device body 1, thereby squeezing the disc-shaped air chamber 7 located directly above the cavity 2. This causes the air inside the air chamber 7 to be delivered to the cavity 2 through the air outlet hose 9, directly impacting the liquid air freshener inside the cavity 2. The bursting of air bubbles accelerates the evaporation of the air freshener. When the air chamber 7 is expelled, the one-way valve 8 on the side wall of the air chamber 7 closes because the air pressure inside the chamber is greater than the external air pressure, ensuring that all gas enters the cavity 2 through the air outlet hose 9 without any backflow of gas.

[0023] When the user removes the object from the recessed area on the upper surface of the device body 1, a negative pressure is formed inside the cavity. The one-way valve 8 on the side wall of the air chamber 7 opens because the external air pressure is greater than the internal air pressure. External air enters the air chamber 7 through the one-way valve 8, completing the gas replenishment of the air chamber 7 and preparing for the air pressure trigger when the object is placed next time.

[0024] In this embodiment, the air freshener diffuses outward through the emitting holes 6 on the side wall of the device body 1. Since the emitting holes 6 are located below the wavy skirt 5 and the edge of the skirt 5 is higher than the recessed area of ​​the upper surface, when an object is placed, such as condensation on the outer wall of a water cup, the wavy skirt 5 will block it and prevent it from entering the cavity 2 through the emitting holes 6, thus avoiding dilution or deterioration of the liquid air freshener. Furthermore, the emitting holes 6 are set along the side wall of the device body 1, which can achieve uniform diffusion of fragrance along the circumference of the device, covering a larger area.

[0025] When the user places a hot cup or other heated item on the device, the heat is conducted to the cavity 2 through the elastic silicone of the device body 1, causing the liquid air freshener in the cavity 2 to be heated and accelerate molecular movement, increasing the evaporation rate. After the hot cup is removed, the liquid air freshener will continue to evaporate slowly for a short time, maintaining a low concentration of fragrance through the emission hole 6, avoiding the interruption of the fragrance when the object is removed.

[0026] like Figure 3 As shown, the air cavity 7 is provided with multiple sets of elastic support walls 10. One end of the elastic support wall 10 is fixedly connected to the bottom wall of the air cavity 7, and the other end is fixedly connected to the top wall of the air cavity 7. Multiple sets of elastic support walls 10 are centrally symmetrically distributed inside the air cavity 7 with the axis of the filling tube 3 as the center, and the multiple sets of elastic support walls 10 do not intersect each other.

[0027] In this embodiment, the elastic support walls 10 centrally and symmetrically distributed inside the air cavity 7 can ensure that the air cavity 7 deforms uniformly in each area when compressed by the weight of the object, avoiding excessive local compression that could cause the air cavity 7 to rupture. At the same time, after the object is removed, multiple sets of support walls 10 can simultaneously provide balanced rebound force, helping the air cavity 7 to quickly restore its original volume to efficiently draw in air and ensuring the stability of the air pressure-triggered cycle.

[0028] like Figure 1 As shown, the upper recessed surface of the device body 1 is uniformly provided with multiple sets of protrusions 11, the protrusions 11 are arranged in a honeycomb pattern, and the protrusions 11 and the device body 1 are integrally formed.

[0029] In this embodiment, when an object is placed or slightly shaken, the protrusion 11 can disperse and transmit the external force to the upper surface of the device body 1, causing the top wall of the air chamber 7 to generate a more uniform high-frequency small-amplitude deformation, thereby driving the air chamber 7 to continuously exhaust air to assist the air freshener to dissipate, avoiding the concentration of force at a single contact point, which would cause excessive local deformation or uneven triggering of the air chamber 7; at the same time, the honeycomb structure can increase the contact friction between the concave surface and the placed objects such as water cups and mobile phones, and the limiting effect of the concave shape further improves the stability of the object placement, preventing the object from sliding and shifting when bumped in the vehicle or slightly bumped on the table.

[0030] like Figure 4As shown, the lower wall surface of the device body 1 is provided with anti-slip protrusions 12.

[0031] In this embodiment, the anti-slip protrusions 12 can increase the contact friction with the placement surface, preventing the device body 1 from shifting, sliding, or even tipping over due to external forces, ensuring that the device is always in a stable working position and does not affect its support for the water cup and mobile phone placed on top, as well as the normal realization of subsequent heat conduction and air pressure triggering functions.

[0032] like Figure 1 and Figure 3 As shown, a sealing plug 13 is provided at the filling port 4, and the sealing plug 13 is matched in size to the filling port 4; The sealing plug 13 is made of oil-resistant silicone.

[0033] It should be noted that, in this document, relational terms such as “first” and “second” are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
