Background

In the prior art, an on-vehicle aromatherapy machine is one of the common devices for improving the air quality in the cabin of an automobile, and is generally arranged at the air outlet of an on-vehicle air conditioner, and diffuses fragrance to the environment in the automobile by means of air-conditioning air, wherein the rate and uniformity of fragrance diffusion are two key factors affecting the user's inspection of the aromatherapy machine. In the prior art, many schemes for improving the fragrance diffusion rate of a vehicle-mounted aromatherapy machine are provided, for example, the applicant puts forward a Chinese patent with publication number of CN210617803U and publication date of 2020-05-26, which provides an aromatherapy seat with a solar electric fan, and specifically discloses the following contents: the aromatherapy seat comprises an upper cover and a lower cover, wherein the upper end face of the lower cover is provided with an annular plate, a plurality of first air outlets which are uniformly distributed are formed in the annular plate, an annular shell is sleeved on the outer wall of the upper cover, the lower end of the annular shell is sleeved on the annular plate, the inner side of the annular plate is provided with a fragrance piece placing groove on the upper end face of the lower cover, a fan blade mounting hole is formed in the upper cover, a fan blade and a motor connected with the fan blade are arranged in the fan blade mounting hole, and a second air outlet is formed between the inner wall of the fan blade mounting hole and the fan blade.

According to the scheme, the fan blades are driven to rotate through the motor on the upper cover, so that air in the base body is driven to flow to accelerate the contact between the fragrance sheet and the air flow, the air flow with fragrance is emitted from the first air outlet and the second air outlet, the volatilization of the fragrance sheet can be accelerated, and the fragrance expanding rate is improved. However, there are some potential drawbacks in this solution, for example, in this solution, the fragrance sheet and the fan in the fragrance sheet placement groove are both contained in the space enclosed by the upper cover, the lower cover and the annular housing, and the air flow in the whole space is driven to flow by the rotation of the fan, so that the fragrance is blown out to the external environment. However, as the fragrance sheet is completely placed in the air flow and the air flow in the space is relatively turbulent, the volatilization speed of the fragrance sheet is too high, so that the fragrance diffused by the fragrance machine is aromatic and pungent, discomfort is brought to a user, and the service life of the fragrance sheet is reduced.

In view of this, there is a need for an aromatherapy machine that can slow down the volatilization speed of the fragrance sheet under the condition of guaranteeing the fragrance-spreading rate, so that the fragrance is spread more uniformly, and the fragrance-using experience of the user is improved.

the embodiment of the utility model solves the technical problem that the volatilization speed of the incense piece in the incense seat is too high in the prior art by providing the incense machine 1, so that the service life of the incense piece can be effectively prolonged, and the fragrance emitted by the incense machine is more uniform.

In order to solve the problem of too high volatilization speed of the fragrant sheet, the general idea of the embodiment of the utility model is as follows:

the fragrance releasing space in the shell 10 is divided into an upper cavity and a lower cavity by the air guide cover 13, the fragrance releasing sheet 2 is received in the lower cavity, the fan 12 is received in the upper cavity, and the air flow in the lower cavity is orderly guided to pass through the fragrance releasing sheet 2 and enter the upper cavity by the rotation of the fan 12 on the air guide cover 13 through the communication opening 133, and the volatilization speed of the fragrance releasing sheet can be effectively slowed down because the air flow passing through the fragrance releasing sheet 2 is orderly rather than disordered.

In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 3, a fragrance releasing space is defined in a housing 10, an air inlet 103 is provided at a lower portion of the housing 10, a dome 13, a fan 12 and a fragrance releasing sheet 2 are provided in the fragrance releasing space, the dome 13 is adapted to divide the fragrance releasing space into an upper chamber and a lower chamber, a communication port for communicating the upper chamber and the lower chamber is provided on the dome 13, the fan 12 is received in the upper chamber, and the fragrance releasing sheet 2 is received in the lower chamber. The fan 12 is rotatably supported on the air guide sleeve 13, and by means of rotation of the fan 12, air flow enters from the air inlet and enters the communication port 133 after passing through the fragrance releasing sheet 2.

In this embodiment, the fragrance releasing sheet 2 may be a fragrant substance having a fixed shape, such as a ring-shaped fragrance releasing sheet as shown in fig. 2, and further, a fragrance wax, an insect repellent sheet, etc. may be used instead of the above-mentioned fragrance releasing sheet.
