Description

The utility model relates to technological processes related to air purification and ventilation, namely to devices for air purification, removal of gases, odors, smoke evacuation, etc. in the local area, for example, a nail technician, stylist, beautician, etc.

Known VACUUM CLEANER FOR MANICURE / PEDICURE OFFICE [RU195199 (U1), publ .: 01/17/2020], characterized in that it contains a housing with a compartment located inside the drive fan and a chamber for collecting dust; flexible air duct, fixed with an adjustable tripod on the body and connected by its channel to the dust collection chamber; and a lamp pivotally mounted on a tripod and connected to the duct of the flexible duct; moreover, a cylindrical filter is installed in the dust collection chamber, and the luminaire is made annular, in the center of which the end of the flexible air duct is installed, and the luminaire is configured to adjust the illumination, while the filter is attached to the body using a pressure plate and a sealing ring.

The main technical problem of the analogue is low vibration and noise isolation, since the fan is located in a special compartment, the casing of which is rigidly fixed in the lower part of the case to the inner partition, which is in rigid contact with the inner walls of the case. In addition, the air flow coming from the filter passes directly into the interior of the housing and is not isolated from the walls of the housing in any way.

The closest analogue is an air purifier in a local area (RU200961U, published: 11/20/2020), containing a housing, a fan unit with a fan, a cylindrical filter, a flexible air duct, an adjustable stand, a ring-shaped lamp, characterized in that a filtration unit is mounted to the opening inside the housing , in the lower part of which a fan unit with a fan is mounted, the inlet of the filtration unit is aligned with the opening in the upper housing cover and with the opening in the hinged housing cover, mounted above the upper cover, the filter is mounted in the filtration unit through the inlet of the said unit and rests on the upper cover housing.

The prototype describes that vibration and noise isolation is mounted between the filtration unit and the casing, to the casing of which a support platform is fixed, on which the fan is fixed.

In the prototype, vibration and noise isolation is provided better than in the previous analogue, since the air flow coming from the filter passes directly into the inner space of the casing of the filtration unit, thereby, it is isolated from the walls of the case.

However, the structural arrangement of the vibration and noise isolation system is not described.

The technical problem of the prototype is also the fact that vibration and noise isolation in it is also imperfect.

This is explained as follows. The filtration unit and the fan unit are represented by separate insulating casings, the entire vibration protection of which consists in an abutment with elastic gaskets against the inner and upper walls of the case.

In this case, the fan unit rigidly rests on the bottom of the case, the filtration unit rigidly rests on the fan unit itself, and the fan rigidly rests on radial stops that rest on the walls of the fan unit.

Thus, the main load of the weight of the fan unit and the filtration unit is borne by the bottom, which easily transfers vibrations and fur coats from them.

The task of the utility model is to create such an air purifier in a local area, which provides effective vibration and noise isolation.

The technical result of the utility model is to increase vibration and noise insulation protection.

The specified technical result is achieved due to the fact that the declared air purifier in the local area, containing a housing, a fan, a flexible air duct, an adjustable stand, a ring-shaped lamp and a filter located inside an insulating casing, and between it and the inner side walls of the housing there are elastic gaskets, on a fan is fixed to the support platform, and the support platform itself is fixed through radial stops, characterized in that the insulating casing is fixed to the inner side of the upper part of the body, made of plastic and consisting of inner and outer cavities, and a filter is placed in the inner cavity, and the outer cavity interacts with the casing through elastic gaskets, and the fan is placed inside a plastic casing, in which the upper part of the intake opening adjoins the lower part of the inner cavity of the insulating casing.

Preferably, the filter can be installed in the inner cavity of the insulating casing with an abutment on the top walls of the filter cover.

Preferably, in addition to its lower part, the insulating casing is made cylindrical and consists of inner and outer cavities, a filter is placed in the inner cavity, and the outer cavity interacts with the body through elastic gaskets. In this case, the fan can be placed inside a plastic casing, in which the upper part of the intake opening adjoins the lower part of the inner cavity of the insulating casing. In this case, the filter can be in the inner cavity of the insulating casing with an emphasis on its upper walls with a filter cover.

Preferably, with its lower part, the insulating casing is made with a tapered and terminating circular hole, the ends of which are fixed abutting the circular hole in the bottom of the housing.

Preferably, the radial stops are made of plastic and are fixed at their ends to the tapered part of the insulating casing. In this case, the arrangement of the radial stops can be made symmetrically relative to the fan rotation axis.

Preferably, the radial stops are made in the form of polygonal-shaped plates of the same type, in which the smallest of the sharp corners is adjacent to the support platform. In this case, each of such radial stops can be fixed with its end to the supporting surface or to the tapering part of the insulating casing with a slope to one side.

Preferably, elastic spacers are installed between the outer walls of the insulating casing and the inner side walls of the housing at the places of the shortest distance between them.

Preferably, the lower part of the insulating casing is made with a tapered and terminating circular hole, the ends of which are fixed by shrinking inside the diameter of the circular hole in the bottom of the housing. In this case, the ventilation grill installed at the bottom of the opening of the bottom of the housing can have an annular protrusion on the inner side, the outer diameter of which corresponds to the diameter of the circular opening of the tapered part of the insulating casing.

It is possible that the insulating casing with its lower part is made with a tapering and terminating circular hole, the ends of which rest on the edges of the circular hole in the bottom of the housing. In this case, it is preferable that an elastic annular gasket is installed at the edges of the ends of the circular opening of the insulating casing.

Implementation of the utility model

The declared air purifier in the local area contains (see Fig. 2) a housing, a fan, a flexible air duct, an adjustable stand 30, a ring-shaped lamp 33 and a filter, where the latter is located inside an insulating casing.

Elastic spacers 8 are located between the insulating casing and the inner side walls 1 (see Fig. 1) of the housing 8. A fan 5 is fixed on the support platform 7, and the support platform 7 itself is fixed through the radial stops 3.

What is new is that the insulating casing is made of plastic and is fixed to the inner side of the upper part of the housing 36 (see Fig. 5), for example, using screws 19.

Also, the insulating casing is made consisting of an inner 10 and an outer 9 cavities, moreover, a filter 20 is placed in the inner 10 cavity, and the outer cavity 9 interacts with the body through elastic gaskets 8.

In this case, the fan 5 is located inside the plastic casing 11, in which the upper part of the intake hole adjoins the lower part of the inner cavity 10 of the insulating casing.

Such a design of the insulating casing, made of plastic, suspended from the inner side of the upper part of the housing 36 and at the same time not rigidly fixed to the casing, where the insulating casing is pressed laterally to the inner side walls 1 of the housing through elastic gaskets 8, provides a more effective vibration compensation in comparison with analogs.

With its lower part, the insulating casing can be made with a tapering and ending round hole, the ends of which are fixed against the round hole in the bottom 4 of the body.

In this case, the radial stops 3 can also be made of plastic and are fixed with their ends to the tapering part of the insulating casing (see Fig. 4, Fig. 5). Due to the fact that the fan 5 is fixed on the support platform 7, and the support platform 7 itself is fixed through the radial stops 3, such an implementation of the fastening of the fan 5 further reduces the transmission of vibration from the fan 5 to the housing, since vibration is transmitted only along the ends of the radial stops 3, which reduces the area of vibration impact on the insulating casing, and with it on the body. The symmetrical arrangement of the radial stops 3 relative to the axis of rotation 6 of the fan 5 makes it possible to even more effectively reduce the transmission of vibration to the casing, since the vibration is distributed evenly over the stops 3, and the vectors of the vibration force are oriented from the center of the axis of rotation 6 in different directions, extinguishing each other.

To further reduce the transmission of vibration, the radial stops 3 can be made in the form of plates of the same type in the form of a polygon, in which the smallest of the sharp corners would adjoin the support platform (see Fig. 4, Fig. 5). Due to the fact that vibration is transmitted to the sharpest angle in the stop plate 3, the area of the plate to which the vibration is transmitted towards the insulating casing is significantly small in comparison with that which holds the abutments 3 on the walls of the tapered part of the insulating casing.

If each of such radial stops 3 is also fixed with its end to the supporting surface or to a tapering part of the insulating casing with a slope to one side (as shown in Fig. 5), this will reduce vertical vibrations, since the plastic of the radial stops 3 in this case, it will be more susceptible to bending and the support platform 7 will be fixed through the radial stops 3 to the insulating casing with a shock absorption effect.

Elastic gaskets 8 can be installed between the outer walls 9 of the insulating casing (see Fig. 1) and the inner side walls 1 of the body at the places of the shortest distance between them (see Fig. 5), where direct contact between the outer walls 9 of the insulating casing and inner side walls 1 of the body. And it cannot be allowed, otherwise strong vibration and noise are possible. Therefore, the installation of spacers 8 in these places provides more effective protection against noise and vibration.

As the fan 5, for example, a centrifugal fan can be used. The fan 5 has a power connection wire 26, which, for example, through a starting capacitor 21, a connection along a wire 27 through a wiring, is brought out to a wiring 22 to a switch 18 and to a power supply wire 23 having an electrical plug 24 at the end.

If necessary, the body of the device can be mounted on wheels 14 for ease of movement.

The insulating jacket can be designed in different ways. A preferred embodiment is one in which the insulating casing with its lower part is made with a tapering and ending round hole, the ends of which are fixed by shrinking inside the diameter of the round hole in the bottom 4 of the body (see Fig. 1). In this case, the ventilation grill 13 (see its view in Fig. 3), installed below the opening of the bottom 4 of the housing, can have an annular protrusion 28 on the inner side, the outer diameter of which corresponds to the diameter of the circular opening of the tapered part of the insulating casing. This design of the insulating casing provides, on the one hand, crimping with the annular protrusion 28 of the insulating grid 13, with which the grid 13 itself is fixed in the bottom 4, and on the other hand, crimping against the edges of the inner diameter of the circular opening of the bottom 4 of the body.

A permissible embodiment is one in which the insulating casing with its lower part is made with a tapering and terminating circular hole, the ends of which simply rest on the edges of the circular hole in the bottom 4 of the body (see Fig. 8). In this case, it is preferable that an elastic O-ring 47 is installed at the ends of the circular opening of the insulating casing, which would enhance vibration damping and noise insulation.

The insulating casing itself, in addition to its lower part, can be cylindrical in shape and consisting of internal 10 and external 9 cavities (see Fig. 1, Fig. 8). With this embodiment, a filter 20 can be placed in the inner cavity, and the outer cavity 9 interacts with the casing through elastic gaskets 8. In this case, the fan 5 can be placed inside the plastic casing 11, in which the upper part of the intake opening adjoins the lower part of the inner cavity 10 insulating casing. The filter 20 itself can be located in the inner cavity 10 of the insulating casing with an emphasis on its upper walls by means of the filter cover 25.

The principle of fixing the filter 20 inside the housing can be implemented in any way, since this does not affect the reduction of vibration or noise in any way.

So, (see Fig. 6) the inlet for installing the filter 20 in the insulating casing can be aligned with the hole 46 in the top cover of the housing 12 and with the hole in the hinged cover of the housing 2, while the filter 20 rests on its top cover 25 of the housing.

Also, the upper part of the filter 20 can be (see Fig. 7) fixed to the upper part of the housing by means of a pressure plate 42 and fastening screws 45 through a rubber gasket 40. For this, the tripod 30 is removed from the hole 34 so as not to interfere, then the filter 20 lowering the cover 25 about the upper cover of the housing 12 (which in this embodiment is not hinged) is lowered with a stop. After that, a pressure plate 42 is lowered onto the rubber gasket 40, in which there are through holes 43, so that they are aligned with the holes 41 containing the threaded bushings. Fastening screws 45 are screwed into the threaded bushings through the washers 44.

After installing the filter 20 and fixing it as described above and shown in FIG. 6, figs. 7, then the adjustable tripod 30 is inserted, then the connector 16 for the nozzle 17, which is then attached to it, and a corrugated air duct 31 is attached to the nozzle 17, the end of which is inserted into a torus-shaped ring lamp 33, where the ring is an LED lamp 34. After which, using the retainer 32, fix the luminaire 33 to the tripod 30.

Then the device is ready for use.

The principle of operation of the utility model is as follows. Electrical plug 24 is connected to a socket. After the switch 18 is turned on, the power is fed through the wires through the starting capacitor 21 to the fan 5, which starts operation and air leaks.

Air is sucked in through the corrugated air duct 31, then into the branch pipe 17 and then enters the filter area 20, where then the air flow 15 goes along the edges of the filter 20 into the opening between them and the inner walls 10 of the insulating casing, then enters the fan 5 in the area of the plastic casing 11 , from where it then comes out through an opening in the bottom 4 and a ventilation grill 13.

During the operation of the device, the main noise from the movement of air and the fan goes inside the insulating casing, which, due to the fact that it is made of plastic, itself serves as a good sound insulator. Noise is also reduced due to the small contact area between the insulating shell and the housing.

Thus, by eliminating the technical problems of known solutions, namely:

exclusion of rigid fixation of the ventilation zone and fan to the walls and bottom of the case,

excluding the transfer of the main load of the weight of the fan unit and the filtration unit on the bottom,

which is generally realized by freely hanging the insulating casing to the upper part of the body and minimizing the stop on the bottom, it was possible to achieve the task of creating such an air purifier in the local area, which provides effective vibration and noise isolation.

During the tests, it was experimentally found that the noise reduction in comparison with the prototype was at the level of 22-24 dB, and vibration was almost completely eliminated and was practically not felt when using the device as a vacuum cleaner for a manicure / pedicure office.
