The present embodiment provides an acarid eliminator, as shown in fig. 1 to 3, which includes a main housing 100, a dust collection container 200, and a fan body 300. The dust container 200 is detachably provided at an upper portion of the main body housing 100. The bottom surface of the main body housing 100 for contacting the surface to be cleaned is provided with a dust suction port 1. While the other surface of the main housing 100 away from the bottom surface is provided with an air outlet 2.

In this embodiment, as shown in fig. 4, a main air duct of the mite controller is provided in the main housing 100, and includes a front air duct member 10 and a rear air duct member 20.

As shown in fig. 1 to 4, the dust collection container 200 is disposed between the front air duct member 10 and the rear air duct member 20, the front air duct member 10 is disposed between the dust collection container 200 and the dust collection port 1, and the rear air duct member 20 is disposed between the dust collection container 200 and the air outlet 2, thereby forming a through air flow passage from the dust collection port 1 to the blower body 300 through the dust collection container 200 and then to the air outlet 2.

As shown in fig. 5, the front air channel member 10 extends obliquely upward from front to rear. The front air duct member 10 is provided at a front end thereof with a first air flow inlet 3 and at a rear end thereof with a first air flow outlet 4. The first air flow inlet 3 is abutted against the dust collection port 1, and the first air flow inlet 3 is abutted against the inlet of the dust collection container 200.

The first air flow outlet 4 is higher than the first air flow inlet 3. The front duct member 10 is hollow and has a first duct provided therein from the first air flow inlet 3 to the first air flow outlet 4. The whole first air channel is inclined upwards from front to back, and the first air channel is preferably a straight air channel.

As shown in fig. 5 to 6, the rear air channel member 20 integrally includes an air channel portion 21 on the front side and a housing portion 22 on the rear side, front and rear. The machine shell 22 is horizontally arranged along the front-rear direction; the fan body 300 is disposed in the housing portion 22 in the front-rear direction; the air inlet 5 of the blower body 300 is forward directed.

A second air duct is provided in the air duct portion 21, and communicates with the inner cavity of the housing portion 22. The end of the second air duct is abutted against the air inlet of the fan body 300. The front end of the air channel portion 21 is provided with a second air flow inlet 5, and the housing portion 22 is provided with a second air flow outlet 6. The second air inlet 5 is abutted against the outlet of the dust collection container 200; the second air flow outlet 6 is butt-jointed with the air outlet 2.

One of the outstanding characteristics of the main machine air duct structure is that the air duct between the dust collecting container 200 and the fan body 300 is integrally formed with the housing portion 22 surrounding the fan body 300.

In the conventional art, the dust suction fan is composed of a housing and a fan body 300, the dust suction fan is disposed in an air chamber, and an air channel portion 21 between the dust collecting container 200 and the air chamber is assembled and connected to the housing by means of a snap connection, a screw connection, a fastening connection or a glue connection.

This results in a front-to-back assembly gap between the two, so that the tightness here needs to be further ensured by the sealing member, which is dependent on the quality of the sealing member and more on the assembly precision between the components. And because the dust absorption fan is easy to vibrate when running, the assembly connection is further caused to be easy to loosen, the poor sealing is caused, and the wind efficiency of the mite removal instrument is influenced.

In this embodiment, the casing 22 surrounds the fan body 300, and protects and supports the fan body 300, so that the fan is a replacement of the casing of the original dust-absorbing fan. The novel dust collection fan has the advantages that the original wind cavity structure and the shell of the dust collection fan are combined into a whole, so that the sealing requirement between the dust collection fan and the wind cavity is reduced, the air tightness of the equipment is ensured more easily, the use of parts is reduced, the cost is saved, and the weight of the equipment is reduced.

The front and rear integrated forming of the air duct portion 21 and the machine shell portion 22 omits the assembly process of the air duct and the air cavity, and no front and rear assembly gap exists. Even if the motor vibrates during running, the front and back separation of the motor and the motor can not occur. Therefore, the assembly of the main air duct and the fan body 300 is more stable, and the air tightness is better.

It should be noted that the blower body 300 is circumferentially sealed from the housing portion 22 such that the inlet and outlet sides of the blower body 300 are isolated. The air flow is ensured to circulate only through the inside of the fan body 300 as much as possible between the air inlet and the air outlet of the fan body 300. This seal is also required in the conventional suction fan. The second air flow outlet 6 is provided at the rear side of the housing portion 22, that is, at the air outlet side of the blower body 300.

As shown in fig. 4, in this embodiment, the second air duct is disposed substantially horizontally, and the center line of the second air duct is located at the same height as the center of the air inlet 5 of the fan body 300. Therefore, the air flow entering from the second air flow inlet 5 is in a flat feeding state, the turning of the air flow in the upper and lower directions is reduced, the linear speed of the air flow is increased, the efficiency is improved, and the wind noise is reduced.

In the present embodiment, the housing portion 22 is disposed along a center line of the main body housing 100. The first air flow outlet 4 and the second air flow inlet 5 are laterally juxtaposed, and are respectively positioned at two sides of the center line of the main machine housing 100.

As shown in fig. 6, the air channel portion 21 includes a first air channel section 211 on the front side and a second air channel section 212 on the rear side; the upper side of the first air channel section is provided with a second air flow inlet 5; the rear side of the second air duct section is connected with the housing part 22 and is communicated with the inner cavity of the housing part 22.

The first air duct section is shorter, which is the transition between the second air duct section and the dust container 200, in order to provide a second air flow inlet 5 for interfacing with the dust container 200. The cross-sectional size of the first duct section is thus dependent on the size of the second air inlet 5, which second air inlet 5 is dependent on the corresponding counter-interface of the dust collection container 200.

The second duct section extends obliquely from one side of main housing 100 to the center line of main housing 100 and is connected to the centrally located housing portion 22. And the axis of extension of the second duct section is at an obtuse angle to the midline of the housing portion 22. The arrangement reduces the obstruction of the air duct on the premise of reasonably distributing the gravity center, and ensures the smoothness of the air duct.

As shown in fig. 5, 11-12, the front air duct member 10 is provided with a first annular end face M surrounding the first air flow outlet 4; the rear duct member 20 is provided with a second annular end face N surrounding the second airflow inlet 5; the first annular end face M and the second annular end face N are arranged laterally side by side and substantially in the same plane. The first and second annular end surfaces M, N being located in the same plane further facilitates assembly with the host housing 100.

In the present embodiment, as shown in fig. 3, the inner wall of the upper case 102 of the main body case 100 has two through-hole pair interfaces opposite to the first air flow outlet 4 and the second air flow inlet 5, and recessed grooves 7 communicating with the first annular end face M and the second annular end face N are formed at the periphery and the interval of the two through-hole pair interfaces. The concave groove 7 is internally provided with a sealing member 8, the first annular end face M and the second annular end face N are embedded into the concave groove 7, and the first annular end face M and the second annular end face N are tightly pressed against the sealing member 8 to realize simultaneous sealing.

Preferably, as shown in fig. 5, the first annular end surface M and the second annular end surface N are both in a square structure in a shape of a Chinese character 'hui'. The recess 7 is thus shaped like a Chinese character 'ri', the adjacent edges of the first and second annular end faces M, N simultaneously pressing against the sealing member 8 part in the bar p of the recess 7. The tightness of the two butt joint positions can be enhanced, and the sealing component at the cross bar can simultaneously play a role in sealing the two butt joint positions.

Preferably, the first annular end face M and the second annular end face N are inclined upward from front to rear. This is to accommodate the inclined dust container 200 so that the air flow can be smoothly introduced into the corresponding parts.

As shown in fig. 8, the rear duct member 20 includes an upper duct case 20a and a lower duct case 20b; the upper duct case 20a includes an upper duct portion 21a and an upper case portion 22a; the lower duct case 20b includes a lower duct portion 21b and a lower case portion 22b; the upper air channel portion 21a and the lower air channel portion 21b enclose to form an air channel portion 21; the upper housing portion 22a and the lower housing portion 22b enclose the housing portion 22. The blower body 300 is assembled into the rear duct member 20 by the disassembly and assembly of the upper duct case 20a and the lower duct case 20 b.

As shown in fig. 9, the upper air channel portion 21a includes a second annular end face N and an upper rear air channel wall L; the lower air channel portion 21b includes a lower rear air channel wall Y. The lower rear duct walls Y are arranged substantially in parallel, which results in a substantially horizontal arrangement of the second ducts of the duct portion 21, facilitating the transport of the air flow. And the upper rear duct wall L is inclined upward from front to rear. With this arrangement, the inlet cross section of the second air duct is larger than the outlet cross section, thereby forming a confluence function and improving the flow rate. Therefore, the inner wall of the upper rear air duct wall L has the function of converging and guiding.

Preferably, the upper rear duct wall L has an inclination angle of less than 5 ° with respect to the horizontal direction.

As shown, the front air duct member 10 includes an upper front air duct wall 11 and a lower front air duct wall 12; the upper front air duct wall 11 and the lower front air duct wall 12 are inclined upward from front to back so that the first air duct is inclined.

The lower front duct wall 12 is inclined at an angle greater than the lower front duct wall 12 so that the inner diameter of the first duct gradually decreases from bottom to top. The inner diameter of the air duct is gradually reduced to form a converging effect, so that the flow speed is increased, the external air carrying dust impurities rapidly enters the dust collection container 200, and the suction force of the equipment is further increased.

As shown in fig. 6 to 7, the housing 22 includes a base 221 and air outlet duct bodies 222 located at both sides of the base 221 and extending laterally; the second air outlet 6 is disposed at the end of the air outlet duct 222. The air blown out of the fan body 300 is directly led to the air outlet 2 of the main machine housing 100 through the air outlet air duct body 222, so that poor heat dissipation and poor stability of the equipment caused by the fact that hot air flows are convolved and remained inside the equipment are avoided.

Preferably, as shown in fig. 9 to 10, the bottom of the base 221 is provided with an air flow hole f, and both sides of the base 221 are provided with half frame protrusions 201 extending laterally. A U-shaped baffle 202 is sealingly wrapped around the underside and side of the base 221, thereby forming an outlet duct 222 with the half-frame protrusions 201 and the bottom of the base 221.

Of course, depending on design requirements, an air flow outlet e is also provided at the bottom of the U-shaped baffle 202. The bottom of the main body case 100 is provided with a fragrance module 500, and fragrance is diffused outwards by using hot air flow of the fan body 300.

Preferably, as shown in fig. 4, the main body case 100 includes a bottom chassis 101, and the first air duct member and the second air duct member are fixed to upper sides of the bottom chassis 101. The bottom surface of the bottom case 101 is a bottom surface of the main housing 100, i.e. an acting surface acting on a surface to be cleaned.

As shown in fig. 3, the lower side of the bottom case 101 is provided with a dust collection opening 1 and an ultraviolet window K which are arranged transversely. The ultraviolet sterilizing lamp is arranged at the inner side of the ultraviolet window, and irradiates ultraviolet rays outwards through the ultraviolet window. The inner side of the dust collection opening 1 is preferably provided with a rolling brush T, and brush strips of the rolling brush have the function of beating and brushing the objects to be cleaned. The bottom case 101 of the main body case 100 at the suction port 1 is thus formed with a lateral long groove having an arc bottom surface, and further an arc arch 9 is formed at the upper side of the bottom case 101.

As shown in fig. 3-4, the arcuate arch 9 has a substantially integral front and rear side as seen from the view. The first air duct member is connected to the rear side of the arc-shaped arch 9, the arc-shaped arch 9 is provided with an arc-shaped butt joint opening 91 where the first air flow inlet 3 is butt-jointed, and the first air flow inlet 3 is an arc-shaped opening, so that compared with a planar structure with the same projection area, the first air flow inlet 3 has a larger area, and the dust collection effect is better.
