Description

Mosquito trap with increased suction

The present invention relates to a mosquito trapping lamp, in particular to a mosquito trapping lamp for inhaling mosquitoes by air flow.

The summer climate in my country is hot and humid, which is very suitable for mosquitoes to grow. Mosquitoes can carry germs or viruses, and use their flying ability to spread diseases (such as dengue fever). Therefore, every year, the government allocates large sums of money to improve the stagnant water environment to eliminate vector mosquitoes. Mosquito traps are commonly used in domestic environments to kill mosquitoes.

There are many mechanisms for mosquito traps to catch mosquitoes, one of which is to use a fan to generate airflow, thereby sucking the mosquitoes into the box. A conventional mosquito trapping lamp utilizing airflow to trap mosquitoes is disclosed in the new patent publication No. M564333. It has a cylindrical casing with a fan inside. The casing is provided with a suction port near the top. Afterwards, a negative pressure will be formed at the suction port, and the nearby mosquitoes will be sucked for the purpose of catching mosquitoes. However, in the above-mentioned conventional structure, from the position of the suction port to the fan, the casing system is a straight cylinder with the same inner diameter, so that the airflow generated by the fan will not increase the suction force at the suction port, so that the mosquito-catching efficiency is not good. Akira's shortcomings. In order to increase the suction force, the output power of the fan must be increased, which in turn causes the cost problem of high power consumption.

In view of this, how to improve the above problem is the primary problem to be solved by the present invention.

The main purpose of the present invention is to provide a mosquito trapping lamp with increased suction, which sucks mosquitoes by air flow, and increases the air flow speed by using the change of the space size in the housing to achieve the effect of improving the mosquito trapping efficiency.

In order to achieve the aforementioned purpose, the present invention provides a mosquito trap lamp capable of increasing suction, comprising: A hollow shell has an upper section, a middle section and a lower section connected in sequence, wherein the inner diameter of the upper section is smaller than the inner diameter of the middle section, the upper section is provided with a suction port, and the lower section is provided with an air outlet ; a lamp provided in the housing; A fan arranged in the lower section of the casing is used for generating the airflow flowing from the suction port toward the air outlet.

In one embodiment, the upper section has a top, and the top protrudes downward from an outer ring wall and an inner ring wall, and the two are connected by a plurality of ribs to form a plurality of intervals, and the lamp is provided with a plurality of spaces. Inside the inner ring wall, the suction port is arranged on the outer ring wall and communicates with the interval space. Preferably, the number of the suction openings is less than the number of the partition spaces, and only part of the partition spaces are connected to the suction openings.

Preferably, the casing is provided with a control unit that is electrically connected to the lamp and the fan for controlling the opening and closing of the lamp and the fan.

Preferably, the inner diameter of the middle section gradually expands from the upper section to the lower section.

Preferably, the suction port is provided with a reflective sheet.

Preferably, the air outlet is provided with a filter screen.

Preferably, the upper section and the middle section of the casing are transparent.

The above-mentioned objects and advantages of the present invention can be easily understood from the detailed description and accompanying drawings of the following selected embodiments.

Please refer to FIGS. 1 to 3 , which are the mosquito traps provided by the present invention which can increase the suction force, including a casing 1 , a lamp part 2 and a fan 3 . The housing 1 has an upper section 11 , a middle section 12 and a lower section 13 connected in sequence, wherein the upper section 11 and the middle section 12 are integrally connected and are transparent, the middle section 12 and the lower section 13 are fitted or Combine with thread. The inner diameter of the above-mentioned upper section 11 is smaller than the inner diameter of the middle section 12; in this embodiment, the middle section 12 is formed in a cone shape, and its inner diameter gradually expands from the upper section 11 to the lower section 13, so that the upper section is made The space enclosed by 11 is smaller than the space enclosed by the intermediate section 12.

On top of that, the upper section 11 has a top 111, and the top 111 protrudes downward with an outer ring wall 113 and an inner ring wall 112, wherein the inner ring wall 112 encloses an inner space 51, and the outer ring wall 113 and the outer ring wall 113 extend downward. The inner ring walls 112 are connected by a plurality of ribs 114 to form a plurality of spaced spaces 52A and 52B. The outer ring wall 113 is provided with a plurality of suction ports 14 connected to the partition space 52A, wherein the number of the suction ports 14 is less than the number of the partition spaces, so that only part of the partition space 52A communicates with the outside through the suction port 14 Connected. The above-mentioned suction port 14 is provided with a reflective sheet 141 for reflecting light to attract mosquitoes.

The lamp 2 is disposed on the top 111 of the upper section 11 and extends downward in the inner space 51 to attract mosquitoes by emitting light.

The fan 3 is disposed inside the lower section 13 of the casing 1, the lower section 13 is provided with a plurality of air outlets 15, and the air outlet 15 is provided with a filter screen 151, the fan 3 is used for generating from the suction port 14 toward the outlet The airflow flowing through the tuyere 15 makes the inside of the housing 1 form a negative pressure, thereby generating suction at the suction port 14 .

The above-mentioned lamp 2 and the fan 3 are switched on and off by a control unit 4 located at the top 111 of the upper section 11, including a switch 41 and a circuit board 42, and the lamp 2 and the fan 3 are electrically connected to the circuit Board 42, which can be controlled by switch 41.

With the above structure, the present invention utilizes the lamp 2 to emit light to attract mosquitoes to approach, and utilizes the fan 3 to generate the airflow flowing from the suction port 14 toward the air outlet 15, so that a negative pressure is formed inside the housing 1. , so as to inhale the approaching mosquitoes from the suction port 14 to achieve the effect of catching mosquitoes, and the filter screen 151 of the air outlet 15 can prevent the dead mosquitoes from being blown out. Due to the shape of the housing 1, that is, the inner diameter of the upper section 11 is smaller than the inner diameter of the middle section 12, and the space enclosed by the upper section 11 is smaller than the space enclosed by the middle section 12, the airflow passes through the suction port 14 The speed of the suction port 14 will increase, thereby increasing the suction force at the suction port 14, so that the mosquitoes are more easily inhaled and the mosquito-catching efficiency is improved.

Furthermore, the present invention further divides the inner space 51 and the interval spaces 52A, 52B by the inner ring wall 112 and the rib 114 in the space enclosed by the upper section 11, and only the interval space 52A is formed. It can be communicated with the outside world through the suction port 14, so that the airflow generated by the fan 3 can only flow through the interval space 52A at the upper section 11, which is equivalent to more restricting the effective space for airflow, and the airflow passes through the suction port 14. The speed of the suction port 14 will be faster, so that the suction force at the suction port 14 will be further increased, and the mosquitoes are more likely to be sucked in, thereby improving the mosquito-catching efficiency.

However, the disclosure of the above embodiments is only used to illustrate the present invention, not to limit the present invention, and the replacement of equivalent elements should still belong to the scope of the present invention.

To sum up, those skilled in the art can understand that the present invention can achieve the above-mentioned purpose, and it complies with the provisions of the Patent Law.
