Technical Field

The invention relates to a mosquito isolation device, in particular to an air curtain mosquito isolator.

Background

Mosquito nets are generally adopted for isolating mosquitoes around the bed, but in the using process, the mosquito nets are inconvenient to go in and out, so a new technical scheme is needed to solve the problem.

Through retrieval, the patent document with the publication number of 206874197U is disclosed by the national intellectual property office in 2018, 1 month and 12 days, and the invention belongs to the technical field of building materials and particularly relates to a door and window mosquito preventing device. The door and window mosquito prevention device comprises a blowing device and a control device, wherein the blowing device is arranged on the outer side of a door and a window, the blowing device is connected with the control device, and when a user opens the door and the window or before the door and the window are opened, the control device controls the blowing device to be opened; the air outlet position of the blowing device is at least positioned at the upper end of the door, and the air outlet direction has an outward-opening included angle relative to the door body. The door and window mosquito prevention device provided by the invention can effectively prevent mosquitoes from entering a room by blowing air through the air blowing devices before and after the door is opened. The linear wall type air curtain adopted by the technical scheme of the patent can only be used for doors and windows and cannot be used at the periphery of a small-area bed.

In order to solve the problems and realize the practical function at the bedside, the invention relates to an air curtain air conditioning bed which comprises a bed body, wherein the tail of the bed body is provided with an air inlet, air outlets are arranged at two sides of the bed body, the inner side of the air outlet is provided with a fan, an air direction regulator is arranged on the air outlet, a cooling coil is arranged in the bed body, a water inlet of the cooling coil is communicated with a water outlet of a refrigerating device, and a water outlet of the cooling coil is communicated with a water return port of the refrigerating device. The invention is characterized in that an air inlet is arranged at the tail part of a bed, air outlets are arranged on two sides of the bed body, a cooling coil is arranged in the bed body, hot air in a bedroom enters the interior of the bed body through the air inlet and exchanges heat with the cooling coil in the bed body, the hot air is changed into cold air, the cold air is blown out from the air outlets, an arc-shaped air curtain is formed on two sides of the bed body through the air outlets, the space above the bed body is separated from other spaces in the bedroom, and the cold air refrigerates the space above the bed body, so that the purposes of cooling and refrigerating are achieved, and meanwhile, healthy.

The above patents suffer from the following drawbacks: firstly, the effect of separating mosquitoes is not good: because the air is blown upwards from the two sides of the bed and the air is sucked from the bed tail, a completely closed air curtain is not formed, and the flying of mosquitoes can not be effectively prevented; secondly, the blowing direction is upward, and the blown air is still cold air, so that an air curtain cannot be formed, and if the air curtain is formed, great electric energy is consumed; thirdly, the function is single, does not have the function of collecting the mosquito kill mosquito.

Disclosure of Invention

In order to overcome the above disadvantages, the present invention provides an air curtain closed type mosquito isolator with convenient access and good mosquito isolation effect.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows:

air curtain closed type mosquito isolator, including dustcoat, inner cover, fan and filter screen, the inner cover suit is in the dustcoat, and the annular space between dustcoat and the inner cover is airflow channel, the air outlet of fan and airflow channel's last port intercommunication, the lower port of airflow channel wind that blows off downwards form a closed air curtain, the filter screen is used for preventing the mosquito to blow off along with the wind.

Further, the air flow channel gradually narrows from top to bottom. The design can improve the wind speed.

Further, a plurality of airflow guide vanes are distributed in the airflow channel at intervals along the periphery of the inner cover.

Furthermore, a plurality of air outlet guide vanes are distributed at the outlet of the airflow channel.

Furthermore, the fan comprises a motor and a fan, the motor is positioned in the inner cover, the fan is positioned at the upper port of the outer cover, an output shaft of the motor extends upwards from the inner cover and is connected with the fan, the upper port of the outer cover is an air inlet, and the filter screen is arranged at the upper port of the outer cover.

And the lower end opening of the inner cover is sealed by the bottom cover plate and is fixedly connected with the bottom cover plate by screws.

Further, still include the mosquito collection case, be equipped with light mosquito trapper or smell mosquito trapping agent in the mosquito collection case, the air outlet of mosquito collection case communicates with the last port of dustcoat, the income wind gap department of mosquito collection case is equipped with one-way baffle, one-way baffle makes the mosquito unidirectional movement, can get into the mosquito collection incasement through one-way baffle by the outside to can not fly out the mosquito collection case through one-way baffle.

The mosquito collecting box is of a circular ring structure and is sleeved on the periphery of the air guide cylinder and communicated with the ventilation holes.

The top cover plate seals an upper port of the air duct, the diameter of the top cover plate is larger than that of the air duct, two limiting installation slots are arranged on the bottom surface of the top cover plate, and the two limiting installation slots are parallel to each other and are located on two sides of the air duct; the mosquito collecting box is formed by butt joint of a left half ring and a right half ring, two limiting installation strips corresponding to the two limiting installation slots are arranged on the top surfaces of the left half ring and the right half ring, and the limiting installation strips are inserted into the corresponding limiting installation slots. The left half ring and the right half ring can be precisely butted together by moving along the limit mounting slot.

Furthermore, the upper port of the outer cover is provided with a limiting sleeve, the bottom surface of the top cover plate is provided with a limiting ring, the lower end of the cylindrical filter screen is sleeved on the limiting sleeve, and the upper end of the cylindrical filter screen is sleeved in the limiting ring.

The invention has the beneficial effects that:

due to the adoption of the structure form, a closed air curtain is formed, and the bed is positioned in the area of the closed air curtain, so that the purpose of isolating mosquitoes is achieved, the entrance and the exit are very convenient, and the air-blowing heat-dissipating bed also has the air-blowing heat-dissipating effect;

because the mosquito collecting box is additionally arranged, the mosquito collecting box utilizes the light mosquito-luring device or the smell mosquito-luring agent to lead the mosquitoes to the periphery of the mosquito collecting box, then the mosquitoes are drawn into the mosquito collecting box by the air flow, and the mosquitoes collected in the mosquito collecting box can be air-dried or starved, thereby realizing the effects of collecting the mosquitoes and killing the mosquitoes;

because the structure and the installation mode of the mosquito collecting box are improved, the mosquitoes can fall on the bottom of the mosquito collecting box, the air duct cannot be blocked, the mosquitoes in the mosquito collecting box cannot be cleaned for a long time, and the mosquito collecting box has the characteristic of convenient use.
