It should be understood that the following text is only used to describe one or more specific embodiments of the present invention, and does not strictly limit the protection scope of the specific claims of the present invention.

Example 1

As shown in FIGS. 1-5, 7 and 8, it is the first embodiment of the present invention. This embodiment provides a microphone with sterilization and sterilization function. A circuit cavity 11 , a shunt cavity 12 and a liquid storage cavity 13 are provided, and the shunt cavity 12 is located at the lower end of the circuit cavity 11 , the outer side of the circuit cavity 11 is provided with a limited through slot, and the outer side of the shunt cavity 12 is evenly opened with a plurality of shunt holes , the interior of the liquid storage cavity 13 is injected with disinfectant, the interior of the circuit cavity 11 is fixedly installed with an audio circuit board 15, the upper end of the audio circuit board 15 is equipped with a pickup, and the pickup and the audio circuit board 15 are electrically connected, and the outer sleeve of the pickup A protective cover 16 is provided, and the surface of the housing 10 is also fixedly connected with a support plate 17 located under the protective cover 16, and further includes:

The drainage tube 14, the drainage tube 14 is located inside the liquid storage cavity 13, and the upper end of the drainage tube 14 extends to the inside of the shunt cavity 12, so that the liquid storage cavity 13 and the shunt cavity 12 form a communication structure;

Nozzle 18, the nozzle 18 is fixed inside the support plate 17, and the input end of the nozzle 18 and the shunt chamber 12 are connected by a shunt pipe, and the nozzle direction of the nozzle 18 is inclined toward the protective cover 16, and the nozzle 18 is inclined to be arranged, which is conducive to fogging The disinfectant is close to the protective cover 16;

a holding type pressure supply mechanism 20, the holding type pressure supply mechanism 20 is assembled on the casing 10, and the holding type pressure supply mechanism 20 and the liquid storage chamber 13 communicate with each other;

The anti-mistouch mechanism 30 is assembled on the shunt cavity 12 and used to block the inlet of the shunt pipe;

The anti-seepage module 50 is assembled at the gap between the protective cover 16 and the pickup, and the anti-seepage module 50 is connected to the holding pressure supply mechanism 20 through the hose 24 .

The anti-seepage module 50 includes a spherical cover 51, the spherical cover 51 is provided with a plurality of through holes 52, and the outer side of the spherical cover 51 is also provided with a number of micro holes 53;

During sterilization, the anti-mistouch mechanism 30 is closed, and the hand presses the grip-type pressure supply mechanism 20 , so that the grip-type pressure supply mechanism 20 supplies pressure to the liquid storage chamber 13 and the hose 24 .

Preferably, the disinfectant is medical alcohol or other disinfectants with strong volatility. Medical alcohol is used here. Because medical alcohol has good volatility, when the misted medical alcohol falls on the protective cover 16, it will be affected by its own The volatilization and anti-seepage module 50 can quickly volatilize under the blowing of the anti-seepage module 50, thereby reducing the content of the alcohol that falls on the surface of the pickup. It is volatile and can volatilize quickly without causing damage to the diaphragm inside the pickup.

It should be noted here that the nozzle 18 has an atomization function, which can atomize and spray the disinfectant, so that the disinfectant in the atomized state can be evenly sprayed on the surface of the protective cover 16, which is convenient to improve the effect of disinfection and sterilization.

Further, a lower nozzle is also provided below the nozzle 18, and the inner diameter of the lower nozzle is smaller than the inner diameter of the nozzle above the nozzle 18. This design is a further extension of the purpose of the present invention, so that when sterilizing, the lower nozzle can also spray. A small amount of disinfectant is dispensed, so that the disinfectant can sterilize the upper and lower parts at the same time. The setting of the inner diameter gap of the nozzle 18 enables most of the disinfectant to be sprayed above, because the microphone head is the key disinfection area, so focus on the microphone head. Cleanup is critical.

Further, please refer to FIG. 3 , the lower end of the housing 10 is connected with a power supply module 40 through conductive pins, and the conductive pins and the audio circuit board 15 are electrically connected by wires, and the power supply module 40 at least includes a protective shell, The power supply element and the jack, the protective shell is assembled on the lower end of the casing 10, the jack is fixed on the upper end of the protective shell, and the jack is matched with the conductive pin, the power supply element is assembled inside the protective shell, and the power supply element and The jack is electrically connected.

When the present invention is in use, the power supply module 40 is disassembled, and the disinfectant is injected into the liquid storage chamber 13. After the disinfectant is injected, the power supply module 40 is assembled on the lower end of the casing 10. When the device is used, the The user's hand squeezes the holding pressure supply mechanism 20, and the holding pressure supply mechanism 20 increases the pressure inside the liquid storage chamber 13, so that the disinfectant inside the liquid storage chamber 13 passes through the drainage tube 14. Entering into the interior of the shunt chamber 12, through the cooperation of the shunt chamber 12 and the shunt pipe, the disinfectant inside the shunt chamber 12 flows to the inside of the nozzle 18, and the disinfectant is sprayed on the surface of the protective cover 16 through the nozzle 18. The surface of the pickup is disinfected and sterilized. At the same time of disinfection, the holding pressure supply mechanism 20 will also provide a part of the air pressure to the anti-seepage module 50, so that the anti-seepage module 50 ejects a part of the gas and forms a weak wind barrier on the outer surface of the pickup. , which can provide a blowing power to the mist-like disinfectant, accelerate the evaporation of the disinfectant, and enable the mist-like disinfectant to fall on the protective cover 16. After the disinfection is completed, because it is a mist-like disinfectant, it is only Droplets will only be formed when a certain amount is accumulated. During the disinfection process, the wind in the micro-holes 53 has blocked them, and under the drive of the wind, its evaporation can be accelerated. Therefore, after the disinfection is completed, the protective cover 16 The sticking disinfectant will not drip easily, so it is not easy to damage the internal pickup while cleaning the microphone head.

It should be noted here that the diameter of the through-hole 52 is much larger than that of the micro-hole 53, and its diameter is designed to be larger in order to reduce the barrier to the sound received by the pickup, and the shape shown in the drawings is actually for better. To understand the structural composition, in the actual composition product, the micropores 53 are very small, so that better disinfection effect can be achieved without affecting the received sound.

As shown in FIG. 3 , the lower end of the liquid storage cavity 13 is provided with an injection port, and the interior of the injection port is equipped with a sealing valve. The sealing performance inside the liquid storage chamber 13 is improved, and the overflow of the disinfectant in the liquid storage chamber 13 is avoided.

As shown in Figures 2-4, the grip-type pressure supply mechanism 20 includes an air bag 21, a one-way air intake valve 22 and a one-way air outlet valve 23. The air bag 21 is annularly fixed on the outside of the liquid storage chamber 13, and the one-way air intake valve 22 is fixed on the air bag 21, the one-way air outlet valve 23 is assembled between the liquid storage chamber 13 and the air bag 21, and the input end of the one-way air outlet valve 23 is located inside the air bag 21, and the output end of the one-way air outlet valve 23 is located in the liquid storage chamber 13, the flow direction of the gas inside the airbag 21 is: from the outside of the airbag 21 to the inside of the airbag 21, and the flow direction of the internal gas of the one-way outlet valve 23 is: from the inside of the airbag 21 to the inside of the liquid storage chamber 13.

Specifically, during disinfection, the air bag 21 is squeezed by the user's hand, and the gas inside the air bag 21 enters the interior of the liquid storage chamber 13 through the one-way air outlet valve 23, so that the pressure inside the liquid storage chamber 13 changes. Then, the disinfectant inside the liquid storage chamber 13 flows to the inside of the shunt chamber 12, and is sprayed to the surface of the protective cover 16 through the nozzle 18, so that the user's own grip strength can be used to realize the disinfection of the microphone head. This process Using the principle of pressure difference, there is no need to provide additional active electrical components, and it has good feasibility.

Further, the material of the airbag 21 is rubber with a rebound function, the outer side of the airbag 21 is evenly provided with a number of anti-skid lines, and the interior of the airbag 21 is provided with a number of rubber support ribs, and the airbag 21 is squeezed by the user's hand. Afterwards, the gas inside the airbag 21 will flow to the interior of the liquid storage chamber 13. Since the material of the airbag 21 has a rebound function, when the user no longer squeezes the airbag 21, the gas outside the device will pass through the one-way air intake. The valve 22 enters the inside of the airbag 21, and cooperates with the rubber support ribs to restore the airbag 21 to its original shape. During the recovery process, the gas will enter from the one-way intake valve 22 to realize the supplementation of the gas. Preferably, it passes through the outside of the airbag 21. The anti-skid pattern can increase the friction force between the user's hand and the airbag 21, which is convenient for the user to better hold.

A blocking block 25 is set at the connection between the airbag 21 and the hose 24, and the blocking block 25 corresponds to the anti-mistouch mechanism 30. When the anti-mistouch mechanism 30 is opened, the blocking block 25 and the anti-mistouch mechanism 30 are clamped together. The hose 24, in this way, when the anti-missing mechanism 30 blocks the shunt chamber 12, the hose 24 can be blocked at the same time, so that when the anti-missing mechanism 30 is running, the anti-seepage module 50 is no longer running. , so as to prevent the gas inside the airbag 21 from leaking out, resulting in the phenomenon that the grip feel is deteriorated.

Specifically, as shown in FIG. 4 and FIG. 6 , the anti-mistouch mechanism 30 includes a choke ring 31 and a lever 32 , the choke ring 31 is rotatably connected to the interior of the shunt cavity 12 , and the outer side of the choke ring 31 is provided with multiple The U-shaped avoidance groove is adapted to the shunt pipe, the lever 32 is fixedly connected to the upper end of the choke ring 31 and is located at the upper end of the shunt cavity 12 , and one end of the lever 32 penetrates the limit outside the circuit cavity 11 . When the U-shaped escape groove is located in the extension direction of the shunt pipe, the airbag 21 is squeezed, and the disinfectant inside the shunt chamber 12 will flow to the nozzle 18 through the shunt pipe; The fixed connection between the lever 32 and the choke ring 31 makes the lever 32 drive the choke ring 31 to rotate, thereby making the U-shaped avoidance groove on the choke ring 31 away from the shunt pipe and no longer located in the extension direction of the shunt pipe. The choke ring 31 blocks the shunt pipe, so that the disinfectant inside the shunt chamber 12 cannot flow to the nozzle 18 through the shunt pipe, further enabling the device to turn on or off the disinfection function according to the needs of the user.

Here, the rotation of the lever 32 can be selected in a manner similar to gear adjustment, so that it has a good positioning effect after being adjusted to a designated position. The specific setting can be provided with an elastic member on the lever 32. The rod 32 is opposite to the ring groove, and a circular groove is opened up and down in the ring groove. Under normal conditions, the elastic member is squeezed into the circular groove to realize the positioning of the lever 32, and when rotating, it can be pressed on the lever 32. The button is set, and the button is pressed to pull the elastic member through the pull wire and other components to unlock it. After the adjustment is completed, stop pressing the button to reset the elastic member, and then it can be positioned again. This method is only one of the processes. In the actual selection process, the more mature parts and components on the market can be used instead, so I won't go into details here.

Further, an arc-shaped sealing plate 33 is fixed on the outer side of the lever 32 , and the arc-shaped sealing plate 33 is in contact with the interior of the circuit cavity 11 . Blocking can improve the airtightness inside the circuit cavity 11 , and prevent dust and water vapor from outside the device from entering the interior of the circuit cavity 11 and causing damage to the audio circuit board 15 .

Preferably, the material of the arc-shaped sealing plate 33 is an elastic material, and the arc-shaped sealing plate 33 is initially in a deformed state. When the lever 32 is rotated, the lever 32 and the arc-shaped sealing plate 33 are fixedly connected, so that the lever 32 drives the arc-shaped sealing plate 33 to rotate. In the process of rotation, it can always be in close contact with the inner wall of the circuit cavity 11 , so as to further improve the sealing performance inside the circuit cavity 11 .

As shown in FIG. 9 , a vertical groove is formed on the blocking block 25, and the hose 24 passes through the vertical groove. The blocking block 25 is also provided with a horizontal groove that communicates with the vertical groove, and the lever 32 can be inserted into the horizontal groove. Internally, it is used to squeeze the hose 24. In this way, when the lever 32 is toggled, it can be inserted into the horizontal groove. At this time, the lever 32 cooperates with the horizontal groove to press the hose 24, so that the hose 24 can be pressed. 24 to block, play a good blocking effect.

Of course, this method is only one of the embodiments, and other components that can block the hose 24 can be selected. The desired effect can also be achieved without being opened under pressure, and details are not repeated here.

It should be noted that the various types of pipes selected in the present invention, such as shunt pipes and other components are all composed of thin tubes with smaller apertures, and the structural composition of the present application is better represented in the accompanying drawings, so it is enlarged. , in fact, the pipes are all thinner, this choice is to provide more pressure in a limited space. A large amount of gas is not required, and both liquid spraying and jetting can be achieved. Therefore, when in use, the air pressure generated by the airbag 21 is sufficient to spray the disinfectant and operate the anti-seepage module 50 .

The working principle of the present invention is:

The power supply module 40 is disassembled, and the disinfectant is injected into the liquid storage chamber 13. After the disinfectant is injected, the power supply module 40 is assembled on the lower end of the housing 10. When the device is used, the hand of the user is used. The airbag 21 is squeezed, so that the gas inside the airbag 21 enters the interior of the liquid storage chamber 13, thereby increasing the pressure inside the liquid storage chamber 13, and the disinfectant inside the liquid storage chamber 13 is squeezed by the gas and flows to the nozzle 18. The inside of the airbag 21 is sprayed to the surface of the protective cover 16 through the nozzle 18 to disinfect and sterilize the surface of the protective cover 16. When the user's hands are no longer pressurized on the airbag 21, the air outside the device passes through the one-way intake valve. 22 enters the inside of the airbag 21, so that the shape of the airbag 21 is restored;

While sterilizing, the holding pressure supply mechanism 20 also provides a part of the air pressure to the anti-seepage module 50, so that the anti-seepage module 50 ejects a part of the gas and forms a weak wind barrier on the outer surface of the pickup, which can prevent the mist-like air The disinfectant provides a blowing power to speed up the evaporation of the disinfectant, so that the mist-like disinfectant can fall on the protective cover 16, and after the disinfection is completed, since it is a mist-like disinfectant, it actually only accumulates to a certain amount. Droplets are formed, and during the sterilization process, the wind in the micropores 53 has blocked them, and under the drive of the wind, its evaporation can be accelerated. It will not drip easily, so it can not easily damage the internal pickup while cleaning the microphone head.

When the user is using the microphone normally, in order to avoid the situation that the disinfectant is sprayed or the airbag 21 is deflated due to operational errors, the user rotates the lever 32 to drive the choke ring 31 to rotate through the choke ring 31. Blocking can prevent the disinfectant inside the shunt chamber 12 from flowing to the nozzle 18, and at the same time squeeze the hose 24 to achieve the blocking effect, thereby enabling the microphone to be used normally, and the entire microphone can be used according to the needs of use. The disinfection function is turned on Or close, for example, after the last person finishes using, rotate the lever 32 to make it unblocked, and the subsequent disinfection process can be quickly realized, which is very convenient to use.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, some improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be regarded as protection scope of the present invention. The structures, devices and operation methods that are not specifically described and explained in the present invention are implemented according to conventional means in the art unless otherwise specified and limited.
