Description

Technical Field

[0001] The invention relates to a mosquito isolating device, in particular to a wind curtain mosquito isolating device. Background Art

[0002] A mosquito net is generally used to isolate mosquitoes around the bed. However, it is very inconvenient to enter and exit the mosquito net during use, so a new technical solution is needed to solve this problem.

[0003] After searching, the State Intellectual Property Office published the patent document with the publication number of 206874197U on January 12, 2018. The present invention belongs to the field of building materials technology, and in particular, relates to a door and window anti-mosquito device. The door and window anti-mosquito device includes a blowing device and a control device. The blowing device is arranged on the outside of the door and window. The blowing device is connected to the control device. When the user opens the door and window or before opening the door and window, the control device controls the blowing device to open; the air outlet position of the blowing device is at least located at the upper end of the door, and the air outlet direction has an outward opening angle relative to the door body. The door and window anti-mosquito device provided by the present invention can effectively prevent mosquitoes from entering the room by blowing air through the blowing device before and after opening the door. The straight wall-type wind curtain adopted in the above patent technical solution can only be used for doors and windows, and cannot be used around beds in small areas.

[0004] In order to solve the above problems and realize the practical function at the bedside, it was found through search that the State Intellectual Property Office published a patent document with publication number 203399877U on January 22, 2014. The present invention relates to an air curtain air-conditioned bed, including a bed body, an air inlet is arranged at the foot of the bed body, air outlets are arranged on both sides of the bed body, a fan is arranged on the inner side of the air outlet, a wind 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 connected with a water outlet of a refrigeration device, and the water outlet of the cooling coil is connected with a water return port of the refrigeration device. The present invention arranges an air inlet at the end of the bed, air outlets on both sides of the bed body, and a cooling coil in the bed body. The hot air in the bedroom enters the bed body through the air inlet, exchanges heat with the cooling coil in the bed body, and the hot air becomes cold air. The cold air is blown out from the air outlet. A wind direction regulator is arranged on the air outlet to form an arc-shaped wind curtain on both sides of the bed body, which separates the space above the bed body from other spaces in the bedroom. The cold air cools the space above the bed body, thereby achieving the purpose of cooling and cooling, and can also achieve healthy and environmentally friendly isolation of mosquitoes.

[0005] The above patent has the following defects: First, the mosquito-isolating effect is not good: since the air is blown upward from both sides of the bed and sucked at the foot of the bed, a completely closed wind curtain is not formed, so it cannot effectively block the flying of mosquitoes; second, the direction of the air is upward, and the air blown out is cold air, so a wind curtain cannot be formed. If a wind curtain must be formed, a lot of electricity will be consumed; third, the function is single and it does not have the function of collecting and killing mosquitoes. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0034] Example 1

[0035] like Figure 1 , 2As shown in Figures 3, 4, 5, 6, and 7, the wind curtain closed mosquito isolator includes an outer cover 1, an inner cover 2, a bottom cover plate 3, a fan and a filter screen. The inner cover 2 is set in the outer cover 1, and the annulus between the outer cover 1 and the inner cover 2 is an air flow channel 5. The fan includes a motor 6 and a fan 7. The motor 6 is located in the inner cover 2, and the fan 7 is located at the upper port of the outer cover 1. The output shaft of the motor 6 extends upward from the inner cover 2 and is connected to the fan 7. The upper port of the outer cover 1 is an air inlet. The bottom cover plate 3 seals the lower port of the inner cover 2 and is fixedly connected with screws. The air flow channel 5 gradually narrows from top to bottom. This design can increase the wind speed. A plurality of air flow guide vanes 8 are distributed at intervals along the periphery of the inner cover in the air flow channel 5, and a plurality of air outlet guide vanes 9 are distributed at the outlet of the air flow channel 5. Under the action of the fan 7, the wind enters from the upper port of the outer cover 1, descends along the air flow channel 5, and blows out vertically downward from the lower port of the air flow channel 5 to form a closed wind curtain.

[0036] It also includes an air duct 14 , a top cover plate 15 and a mosquito collecting box 16 . A plurality of ventilation holes 17 are distributed on the wall of the air duct 14 . The filter screen is a cylindrical filter screen 18 , which is mounted inside the air duct 14 . The lower port of the air guide tube 14 is connected to the upper port of the outer cover 1, the top cover plate 15 is plugged into the upper port of the air guide tube to close the port, and the diameter of the top cover plate 15 is larger than the diameter of the air guide tube 14, and two limit installation slots 19 are provided on the bottom surface of the top cover plate 15, and the two limit installation slots 19 are parallel to each other and located on both sides of the air guide tube 14; the mosquito collecting box 16 is a circular ring structure, which is sleeved on the periphery of the air guide tube 14 and communicated with the ventilation hole 17, and the mosquito collecting box 16 is formed by docking a left half ring 20 and a right half ring 21, and two limit installation strips 22 corresponding to the two limit installation slots are provided on the top surfaces of the left half ring 20 and the right half ring 21, and the limit installation strips 22 are plugged into the corresponding limit installation slots 19. The left half ring 20 and the right half ring 21 can be accurately docked together by moving along the limit installation slots.

[0037] A limiting sleeve 23 is provided at the upper end of the outer cover 1 , a limiting ring 24 is provided on the bottom surface of the top cover plate 15 , the lower end of the cylindrical filter screen 18 is sleeved on the limiting sleeve 23 , and the upper end of the cylindrical filter screen is sleeved in the limiting ring 24 .

[0038] In this embodiment, a one-way partition 25 is provided on the side wall of the mosquito collecting box 16. The one-way partition 25 is composed of a plurality of partition bars 26 distributed at intervals. The cross section of the partition bar 26 is a V-shaped structure. When the partition bar is installed, the opening of the V-shaped structure of the partition bar faces inward and the tip with an angle faces outward. The gap between adjacent partition bars allows mosquitoes to be sucked into the mosquito collecting box through the gap only under the action of wind. In the absence of wind, mosquitoes cannot fly through the gap.

[0039] Working principle: The closed wind curtain of this patent can be circular, elliptical or rectangular. Generally, the diameter of the area closed by the wind curtain should be more than 2 meters. When this patent is installed and used, the wind curtain closed mosquito isolator is hung on the ceiling, and the bed is located directly below the wind curtain closed mosquito isolator. People are in the area closed by the wind curtain, which can not only effectively isolate mosquitoes, but also has the effect of blowing air and dissipating heat; at the same time, it can also collect and kill mosquitoes. Light mosquito attractants or odor mosquito attractants are used to attract mosquitoes to the periphery of the mosquito collection box, and then they are drawn into the mosquito collection box by the airflow. The mosquitoes collected in the mosquito collection box will be dried or starved to death.

[0040] This embodiment is the best implementation scheme, which improves the structure and installation method of the mosquito collecting box in Example 2. The mosquitoes will fall on the bottom of the mosquito collecting box, and will not block the ventilation holes 17 on the air guide tube. The mosquitoes in the mosquito collecting box can be left uncleaned for a long time, so it is easy to use. It not only has the function of isolating mosquitoes, but also has the function of collecting and killing mosquitoes.

[0041] Example 2

[0042] like Figure 8 As shown, the wind curtain closed mosquito isolator of this embodiment only has the function of isolating mosquitoes, and is essentially a net, except that it is a mosquito net enclosed by a wind curtain.

[0043] The wind curtain closed mosquito isolator comprises an outer cover 1, an inner cover 2, a bottom cover plate 3, a fan and a filter screen 4. The inner cover 2 is set in the outer cover 1, and the annulus between the outer cover 1 and the inner cover 2 is an air flow channel 5. The fan comprises a motor 6 and a fan 7. The motor 6 is located in the inner cover 2, and the fan 7 is located at the upper port of the outer cover 1. The output shaft of the motor 6 extends upward from the inner cover 2 and is connected to the fan 7. The upper port of the outer cover 1 is an air inlet, and the filter screen 4 is arranged at the upper port of the outer cover 1 to prevent mosquitoes from being blown out with the wind. The bottom cover plate 3 seals the lower port of the inner cover 2 and is fixedly connected with screws. The air flow channel 5 gradually narrows from top to bottom. This design can increase the wind speed. Under the action of the fan 7, the wind enters from the upper port of the outer cover 1, descends along the air flow channel 5, and the wind is blown out vertically downward from the lower port of the air flow channel 5 to form a closed wind curtain.

[0044] Example 3

[0045] like Fig. 9 As shown, this embodiment is based on the embodiment 2, and a mosquito collecting box 10 is installed at the upper end of the outer cover 1, the air outlet of the mosquito collecting box 10 is connected with the upper end of the outer cover 1, a light mosquito attractant or an odor mosquito attractant is arranged in the mosquito collecting box 10, the four walls and the top surface of the mosquito collecting box 10 are provided with air inlets, and a one-way partition 11 is arranged at the air inlet, the one-way partition allows mosquitoes to move in one direction, and can enter the mosquito collecting box from the outside through the one-way partition, and cannot fly out of the mosquito collecting box through the one-way partition.

[0046] In this embodiment, the one-way partition is composed of a plurality of partition bars distributed at intervals, and a plurality of soft spines 13 inclined toward the mosquito collecting box are distributed on the side of each partition bar 12. The soft spines block the gaps between adjacent partition bars. Only under the action of wind can mosquitoes be sucked into the mosquito collecting box through the gaps along the soft spines. In the absence of wind, mosquitoes cannot fly through the gaps against the spines.

[0047] This embodiment has some disadvantages. The mosquitoes in the mosquito collecting box are easy to fall on the filter. If used for a long time, the mosquitoes will block the filter. Therefore, the mosquitoes in the mosquito collecting box need to be cleaned in time.

[0048] The above description is only a preferred implementation mode of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. It should be pointed out that for ordinary technicians in this technical field, modifications or equivalent substitutions of the technical solution of the present invention do not depart from the protection scope of the technical solution of the present invention.
