Abstract
Description
Technical Field
[0001] This utility model relates to the field of car accessories technology, and in particular to a car air freshener. Background Technology
[0002] The booming development of the automotive industry has greatly driven the development of the car interior accessories industry, with aroma diffusers occupying a significant position as an important component. Aroma diffusers primarily produce fragrance by atomizing aromatherapy oils. Currently, atomization is mainly achieved through three methods: vibration, compression, and heating. Heating atomization involves heating a liquid, causing it to gradually evaporate and form mist particles between 1 and 10 micrometers in size.
[0003] In related technologies, the liquid suction stick of an aromatherapy diffuser is typically inserted directly into the liquid in the mounting chamber, with its bottom fitting against the bottom of the chamber and its top abutting against the heating element. Due to the resisting force, the suction stick can be compressed and shortened over prolonged use. This can lead to insufficient contact between the suction stick and the heating element after liquid replacement, affecting the atomization effect. Summary of the Invention
[0004] The main purpose of this invention is to provide a car air freshener that allows the liquid-absorbing stick to fit more tightly with the heating component, thereby improving the atomization effect and service life.
[0005] To achieve the above objectives, the present invention provides a car air freshener comprising:
[0006] The outer casing has a mounting cavity and a spray nozzle communicating with the mounting cavity;
[0007] A liquid storage bottle is disposed within the mounting cavity and forms a liquid storage tank and a liquid suction channel, the liquid suction channel connecting the liquid storage tank and the spray nozzle; and
[0008] The atomizing assembly includes a heating element, a liquid-absorbing rod, and an elastic element. The elastic element is connected to the bottom wall of the liquid storage tank and extends partially into the liquid-absorbing channel. The heating element covers the opening end of the liquid-absorbing channel and has a misting port that connects the liquid-absorbing channel and the spray nozzle. The liquid-absorbing rod elastically abuts against the heating element and the elastic element.
[0009] In an optional embodiment, the elastic element includes a spring and a puncture needle connected to the spring. The spring is connected to the bottom wall of the mounting cavity, and the puncture needle is inserted into the bottom of the suction rod, with the suction rod elastically abutting against the spring.
[0010] In an optional embodiment, the heating element includes a heating plate and a heat insulation ring. The heat insulation ring is sleeved on the outer edge of the heating plate and connected to the side wall of the mounting cavity. The heating plate abuts against the upper part of the liquid suction rod and has the misting port.
[0011] In an optional embodiment, the heating element has a protrusion on one side facing the liquid-absorbing rod to form a top protrusion, and the heating element has a plurality of mist-passing holes, which are evenly spaced along the circumference of the top protrusion, and the top protrusion abuts against the liquid-absorbing rod.
[0012] In an optional embodiment, the car air freshener includes a control board and a power supply. The control board is installed in the mounting cavity and electrically connected to the heating element, and the power supply is electrically connected to the control board.
[0013] In an optional embodiment, the car air freshener further includes an indicator light and a control switch, which are connected to the housing and electrically connected to the control board.
[0014] In an optional embodiment, the outer casing includes an upper casing, a lower casing, and a middle frame. The middle frame is detachably connected to the upper casing and the lower casing. The upper casing and the lower casing enclose the mounting cavity. The middle frame divides the mounting cavity into a liquid storage chamber and an electrical control chamber. The liquid storage bottle is disposed in the liquid storage chamber, and the control board and the power supply are disposed in the electrical control chamber.
[0015] In an optional embodiment, the lower housing is provided with external threads, the middle frame is provided with internal threads, and the lower housing and the middle frame are threadedly connected.
[0016] In an alternative embodiment, the housing further includes an adhesive plate attached to the lower surface of the lower housing.
[0017] In an alternative embodiment, the absorbent rod is made of sponge.
[0018] The present invention relates to a car air freshener, which includes a housing having an installation cavity and a spray nozzle communicating with the installation cavity. The installation cavity is used to install various components of the car air freshener. A liquid storage bottle is disposed in the installation cavity and has a liquid storage tank and a liquid suction channel. The liquid suction channel communicates with the liquid storage tank and the spray nozzle. The liquid storage tank is used to store liquid to be atomized. The atomized vapor is sprayed outward from the spray nozzle through the liquid suction channel. The elastic element of the atomizing component is connected to the bottom wall of the liquid storage tank and partially extends into the liquid suction channel. A heating element is covered at the opening end of the liquid suction channel and has a misting port communicating with the liquid suction channel and the spray nozzle. The liquid suction rod elastically abuts against the heating element and the elastic element. In this application, the liquid-absorbing rod extends within the liquid-absorbing channel and can absorb liquid from the storage tank. The heating element, which abuts against its upper part, can heat the liquid-absorbing rod to atomize the absorbed liquid. The atomized water vapor flows through the mist outlet to the spray nozzle and finally flows outward from the spray nozzle. The elastic element pushes the liquid-absorbing rod against the heating element, so that the liquid-absorbing rod and the heating element not only fit more tightly, but also, through its elasticity, can avoid the situation where the liquid-absorbing rod is not tightly fitted to the heating element after the atomizing liquid is replaced after compression. Thus, the service life and atomization effect of the car air freshener are better. Attached Figure Description

[0030] Reference Figures 1 to 4 This utility model proposes a car air freshener 100.
[0031] In this embodiment of the utility model, the car air freshener 100 includes a housing 10, which forms an installation cavity (not shown) and a spray nozzle 10a communicating with the installation cavity; a liquid storage bottle 20 is disposed in the installation cavity and forms a liquid storage tank 20a and a liquid absorption channel 20b, the liquid absorption channel 20b communicating with the liquid storage tank 20a and the spray nozzle 10a; an atomizing component includes a heating element 31, a liquid absorption rod 32 and an elastic element 33, the elastic element 33 is connected to the bottom wall of the liquid storage tank 20a and partially extends into the liquid absorption channel 20b, the heating element 31 covers the opening end of the liquid absorption channel 20b and has a misting port 31a communicating with the liquid absorption channel 20b and the spray nozzle 10a, and the liquid absorption rod 32 elastically abuts against the heating element 31 and the elastic element 33.
[0032] Specifically, the outer casing 10 includes an upper casing 11, a lower casing 12, and a middle frame 13. The upper casing 11, lower casing 12, and middle frame 13 can be formed in one piece by injection molding of plastic material, or by mechanical processing such as shearing and stretching of sheet metal material. The middle frame 13 is detachably connected to the upper casing 11 and the lower casing 12, so that the upper casing 11 and the lower casing 12 enclose a circular mounting cavity. The middle frame 13 also divides the mounting cavity into an upper and lower spaced electrical control chamber 11a and a liquid storage chamber 12a. The electrical control chamber 11a is used to install electrical control components such as the control board 40, power supply 50, indicator light 60, and control switch 70. The liquid storage chamber 12a is used to hold the liquid storage bottle 20. This arrangement can prevent the atomized liquid in the liquid storage bottle 20 from flowing to the electrical components such as the control board 40 and power supply 50, thus ensuring the service life and stability of the electrical components to a greater extent. The middle frame 13 is detachably connected to the upper shell 11 and the lower shell 12 respectively. Specifically, the lower shell 12 is provided with external threads, the middle frame 13 is provided with internal threads, and the lower shell 12 and the middle frame 13 are threaded together. The upper shell 11 and the middle frame 13 are connected by screws. Thus, the connection structure of the outer shell 10 is simple and firm, and it is convenient to disassemble and replace the liquid storage bottle 20 and the liquid suction rod 32.
[0033] The car air freshener 100 is also equipped with a control board 40, a power supply 50, an indicator light 60, and a control switch 70. The control board 40 consists of a PCB board and multiple electronic components soldered to its surface. The control board 40 is fixed in the mounting cavity with screws and is electrically connected to the heating element 311, the power supply 50, the indicator light 60, and the control switch 70 through terminal connection wires. The heating element 311 heats the liquid-absorbing rod 32. The indicator light 60 can display the current working status of the car air freshener 100, and the control switch 70 can control the on / off state of the car air freshener 100.
[0034] The liquid storage bottle 20 is also made of plastic material. It includes an upper bottle body and a lower bottle body connected by threads. The upper bottle body and the lower bottle body enclose a liquid storage tank 20a. A liquid suction channel 20b is provided in the upper bottle body. The liquid suction channel 20b has a central axis, which is perpendicular to the liquid storage tank 20a and coincides with the center of the spray nozzle 10a.
[0035] The liquid-absorbing rod 32 is made of sponge and has water absorption properties. The shape of the liquid-absorbing rod 32 is adapted to the shape of the liquid-absorbing channel 20b. It is located between the elastic member 33 and the heating member 31. The liquid-absorbing rod 32 absorbs the liquid in the liquid storage tank 20a and guides the liquid to its upper part, where it is heated and atomized by the heating member 31.
[0036] In this application, the liquid-absorbing rod 32 extends within the liquid-absorbing channel 20b and can absorb the liquid in the liquid storage tank 20a. The heating element 31, which abuts against its upper part, can heat the liquid-absorbing rod 32 to atomize the absorbed liquid. The atomized water vapor flows through the mist outlet 31a to the spray outlet 10a and finally flows outward from the spray outlet 10a. The elastic element 33 pushes the liquid-absorbing rod 32 against the heating element 31. In this way, the liquid-absorbing rod 32 and the heating element 31 are not only more tightly attached, but also, through its elasticity, it can avoid the situation where the liquid-absorbing rod 32 is not tightly attached to the heating element 31 after the atomizing liquid is replaced after compression. Thus, the service life and atomization effect of the car air freshener 100 are better.
[0037] Furthermore, the elastic element 33 includes a spring 331 and a puncture needle 332 connected to the spring 331. The spring 331 and the puncture needle 332 are integrally formed from metal profiles through machining. The spring 331 can be connected to the bottom wall of the mounting cavity by glue or screws. The puncture needle 332 is inserted into the bottom of the suction rod 32. The suction rod 32 and the spring 331 are in elastic contact. By setting the puncture needle 332, the suction rod 32 can be installed more securely.
[0038] Please see again Figure 2 In this embodiment, the heating element 31 includes a heating plate 311 and a heat insulation ring 312. The heat insulation ring 312 is made of heat-insulating elastic silicone rubber material. The heat insulation ring 312 is connected to the middle frame 13 and sleeved on the outer edge of the heating plate 311. The heating plate 311 is made of thermally conductive metal and abuts against the upper part of the liquid-absorbing rod 32, and has a misting port 31a. In this application, the heating plate 311 is installed in the mounting cavity through the heat insulation ring 312, which can prevent heat loss in the mounting cavity and also prevent damage to the electronic components of the car air freshener 100 due to overheating.
[0039] Furthermore, abutting protrusion 313 is formed on the side of the heating element 311 facing the liquid-absorbing rod 32. This abutting protrusion 313 is formed by a stretching process and is circular in shape. Its diameter should be smaller than the diameter of the liquid-absorbing rod 32. The heating element 311 has multiple mist-passing ports 31a, which are evenly spaced along the circumference of the abutting protrusion 313. The abutting protrusion 313 abuts against the liquid-absorbing rod 32. By setting the abutting protrusion 313, the heating area can be further increased, and the atomization effect can be improved. At the same time, the abutting protrusion 313 can be elastically embedded into the liquid-absorbing rod 32, thereby firmly fixing it. The multiple mist-passing ports 31a can improve the mist output efficiency.
[0040] In this embodiment, the outer casing 10 also includes an adhesive plate 14, on both sides of which are provided with glue or adhesive tape. The adhesive plate 14 is attached to the lower surface of the lower casing 12, and the other side can be adhered to the center console of the car, thereby firmly fixing the outer casing 10.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
