Fig. 1 schematically shows a schematic view of a burner device 1 according to an embodiment of the present invention. The incense burning device 1 comprises an air inlet 10, an air outlet 20 and a negative pressure mechanism 30 arranged between the air inlet 10 and the air outlet 20. The negative pressure mechanism 30 is configured to form an air flow path 40 for the flow of gas between the air inlet 10 and the air outlet 20. The air inlet 10 is preferably directed towards the fragranced area 200, so that noxious substances (including gases and solids) generated at the fragranced area 200 can be entrained by the air into the air inlet 10 and proceed along the air flow path 40. The incense burner 1 further includes a purge mechanism 50 in the air flow path 40. When the air carrying the harmful material enters into the purifying mechanism 50 along the air flow path 40, the purifying mechanism 50 can remove the harmful material from the air. Thus, the air leaving the purge mechanism 50 is clean air. The clean air can continue along the airflow path 40 and be discharged back into the environment by the air outlet 20.
The purification mechanism 50 may include, for example, an electrostatic precipitator for removing solid substances from the air among harmful substances. In the embodiment shown in fig. 2, two electrostatic precipitators 51A, 51B are provided along the airflow path 40.
Fig. 6 shows an exemplary structure of the electrostatic precipitator 51A. As shown in fig. 6, the electrostatic precipitator 51A includes an electrifying member 512 and an adsorbing member 513 which are arranged in sequence along the airflow path 40 and spaced apart from each other. The electrical leads 512 are configured to charge, i.e., form into charged particles, solid particles around them. The absorbing member 513 is also charged, and the charged property is opposite to the charged property of the charged particles. For example, the charged particles may have a positive charge, while the adsorbent 513 has a negative charge. In this way, the charged particles can be adsorbed on the adsorbing member 513 and thus be separated from the flowing air.
At least one of the electricity-guiding member 512 and the adsorbing member 513 is preferably plate-shaped, and its surface is parallel to the direction of the air flow path 40. The charging member 512 is advantageous for sufficiently charging the charged particles, and the adsorbing member 513 is advantageous for efficiently adsorbing the charged particles.
Preferably, the adsorption member 513 is an industrial-grade SS316 plate type dust removal plate.
Preferably, a voltage of about 2kV or about 6kV is applied to the adsorbing member 513.
In addition, the adsorption member 513 may include a charging plate and an adsorption layer disposed on a surface of the charging plate. The charged particles are attracted by the charged plate and move toward the charged plate, but are eventually attached on the adsorption layer. The adsorption layer may be made of a material such as felt to which charged particles easily adhere. The charged particles that have been adsorbed on the adsorbing member 513 can be removed by replacing the adsorbing layer. The adsorption layer is configured not to affect the attraction of the charged particles by the charged plate. In addition, the adsorption layer may be configured as a plate, film, sheet, or the like, and may be disposed on the charged plate by clamping, adhering, or spraying, or the like. The adsorbent layer is preferably replaceable.
In a preferred embodiment, as shown in fig. 6, the electrostatic precipitator 51A further comprises a first filter 511 arranged upstream of the electrical conducting element 512 and/or a second filter 514 arranged downstream of the adsorbing element 513 to assist in removing solid particles from the flowing air.
In a more preferred embodiment, at least one of the first filter 511 and the second filter 514 is a HEPA filter.
Preferably, the first filter 511 has a larger mesh diameter than the second filter 514. The specific mesh diameter size can be determined as desired.
In the embodiment shown in fig. 2, the purification mechanism 50 further comprises an adsorption filter 52 downstream of the electrostatic precipitators 51A, 51B. The adsorption filter comprises a box body and active carbon arranged in the box body. The activated carbon can adsorb gaseous substances among harmful substances to remove them from the air. A plurality of adsorption filters 52 may be provided along the air flow path 40 as needed.
Preferably, the adsorption filter 52 is an industrial-grade activated carbon filter capable of removing organic air pollutants.
Preferably, the adsorbent filter 52 is constructed such that the activated carbon therein is replaceable or the entirety thereof is replaceable.
In addition, the negative pressure mechanism 30 may be a fan 30. Preferably, the fan 30 is disposed between the purifying mechanism 50 and the air outlet 20, so that the air passing through the fan 30 is clean air. This is advantageous in order to avoid the fan 30 from becoming dirty, and thus in order to ensure smooth operation of the fan 30.
Preferably, the fan 30 is connected to an inverter, so that the rotational speed of the fan blades in the fan 30 can be adjusted by the inverter. In this way, the amount of airflow entering through the intake port 10 can be controlled.
In a preferred embodiment, as shown in FIG. 2, the purging mechanism 50 is adjacent to the fan 30. In order to ensure that the air leaving the purge mechanism 50 can smoothly enter the fan 30, a flow guide 31 is provided between the purge mechanism 50 (e.g., the adsorption filter 52) and the fan 30. The inlet of the guide 31 communicating with the purge mechanism 50 is larger than the inlet communicating with the fan 30. The flow guide 31 may be, for example, a hollow truncated cone.
In the embodiment shown in fig. 1 and 2, the air intake 10 is above the purification mechanism 50. The incense burner 1 further includes an intake pipe 41 extending in the longitudinal direction, the upper end of the intake pipe 41 being configured with the intake port 10, and the lower end of the intake pipe 41 extending downward to the side of the purification mechanism 50 or beyond the side of the purification mechanism 50 so that the intake pipe 41 communicates with the purification mechanism 50 at the side. The intake pipe 41 surrounds a part of the airflow passage 40. Thus, the air carrying the harmful material flows in a downward direction in the intake duct 41, and when it is about to enter the purifying mechanism 50, it needs to be turned to a horizontal direction (or a nearly horizontal direction) to enter the purifying mechanism 50. At this time, the solid harmful substances (for example, solid particles) entrained in the air are separated from the air flow by inertia, gravity, and the like if the weight is large. In addition, air entering the air intake duct 41 from the air intake 10 may also be entrained with water droplets (e.g., originating from rain) that can also separate from the airflow as it turns. This allows the air to be pre-purified before entering the purifying mechanism 50.
In a preferred embodiment, the intake pipe 41 includes a retention chamber 42 below the communication between the intake pipe 41 and the purification mechanism 50. Heavier solid particles and/or water droplets separated from the air can fall into the retention chamber 42. Because the retention chamber 42 is below the aforementioned communication, the separated solid particles and/or water droplets are difficult to be re-entrained by the airflow into the purification mechanism 50.
In addition, an adhesive material (not shown) may be provided in the retention chamber 42. The attachment material may be a sponge, for example. Solid particles and/or water droplets separated from the air can adhere to the adhering material, so that they can be further prevented from being carried by the airflow again.
Preferably, a closable discharge port 43 is provided at the bottom of the intake pipe 41. The separated solid particles and/or water droplets can be discharged through the discharge port 43. The discharge opening 43 can here be closed by a cover plate which can be connected to the inlet pipe 41 by means of a hinge or snap connection or the like. In the case where the adhesion material is provided, the user can take out or replace the adhesion material through the discharge opening 43.
In addition, in the embodiment shown in fig. 2 and 5, the air outlet 20 is located at the rear side of the incense device 1, i.e., the side facing generally away from the user. Thereby, the user can be prevented from being blown by the air flow exiting from the air outlet 20. In addition, the air outlet 20 can be set as large as possible, so that the flow velocity of the air flow entering the environment through the air outlet 20 can be reduced, and the air flow can be further prevented from causing great influence on the environment.
In the embodiment shown in fig. 1 and 2, the air intake 10 is at the side of the incense area 200, whereby the air intake 10 is arranged at the side of the air intake duct 41 for receiving the air with entrained noxious substances from the incense area 200.
In the embodiment shown in fig. 3-5, the air intake 10 is above the burner region 200, whereby the air intake 10 is configured to face downward or generally downward. For example, as shown in fig. 3, the intake port 10 is provided obliquely downward. This arrangement facilitates a more efficient reception of noxious substance laden air by the air inlet 10.
In the above case, the portion of the air flow path 40 in the intake pipe 41 is configured with the bent section 401. When the air flow passes through the bent section 401, the heavy solid matter and/or water droplets are easily separated from the air flow and impact on the inner wall of the air inlet pipe 41. Solid matter and/or water droplets approaching or adhering to the inner wall of the air inlet pipe 41 are difficult to be carried again by the airflow.
In the embodiment shown in fig. 3 to 5, the incense device 1 further includes a casing 100, and the casing 100 is preferably a rectangular body. The purge mechanism 50 is accommodated in the casing 100 and protected by the casing 100. The upper surface of the housing 100 is formed as a fragrance holder supporting surface 80 on which the fragrance holder 61 is disposed. A burning incense area 200 is formed above the housing incense holder support surface 80.
As shown in fig. 5, a slide rail 81 is provided on the holder support surface 80, and a slide member (not shown) slidably engaged with the slide rail 81 is provided on the bottom of the holder 61. Thus, the fragrance holder 61 can be moved along the slide rail 81 on the fragrance holder support surface 80 to adjust its position as desired.
In addition, as shown in fig. 4, a guide plate 11 may be further provided at the intake port 10. The guide plate 11 is constructed with a plate body and an inclined plate inclined with respect to the plate body, one end of which is connected to the plate body and the other end of which is spaced apart from the plate body to form an opening between the plate body and the inclined plate, the opening forming the air inlet 10. The angle of the inclined plate can be adjusted as required. The projection of the tilting plate on the surface of the plate body can cover the entire opening.
In addition, an isolation net may be disposed at the air inlet 10 to prevent animals such as flying insects from entering the air inlet 41.
Furthermore, a pre-filter screen may also be provided within the intake pipe 41, preferably within the intake pipe 41 adjacent to the intake port 10. The pre-filter screen is preferably an SS316 network. The pre-filter mesh preferably has a mesh size of about 1 mm.
As shown in fig. 4, a caster 70 is provided below the housing 100. The caster 70 is preferably a universal wheel. Thereby, the incense device 1 can be moved easily.
The incense burner 1 can collect harmful substances generated by combustion and prevent the harmful substances from being diffused in the environment. This can prevent the environment from being damaged and can prevent the health of people around the incense burner 1 from being damaged.
The term "extending in the longitudinal direction" in this context is to be understood as extending substantially in the longitudinal direction without excluding local turning.
