The water-absorbing cotton swab atomizer is atomized, and the water mist is driven by the air-conditioning wind to diffuse to the entire room.

In the present invention, the material selection situation of each device:

1. Atomization generating device

(1) Material selection of atomization generating device

1. Bottom plate, left connecting shaft and two hooks: the bottom plate of the atomization generating device needs to support the ultrasonic atomizer and the water storage tank, and the left connecting shaft and two hooks need to support the entire bottom plate and the worm gear pair. The rigidity requirement is relatively large, so it cannot Use general plastics, adopt PVC profiles (plastic steel). PVC profiles have good rigidity and elasticity, especially good heat insulation performance. When the air conditioner is cooling, the air-conditioning wind will not form too many water droplets on the PVC surface.

2. Water storage tank: pp material (polypropylene), which is a non-toxic, odorless, tasteless milky white high-crystallization polymer with a density of only 0.90--"0.91g/cm3, is currently the lightest of all plastics One of the varieties. It is particularly stable to water, the water absorption rate in water is only 0.01%, and the surface rigidity and gloss are relatively good.

3. Worm gear transmission device: In this device, the requirement for the speed of the worm pair is not high, it only needs to rotate slowly within an angle range, but it is required to have better self-locking performance, so the worm pair is required to have better Stiffness hardness, anti-friction, wear resistance, easy running-in performance and anti-gluing ability, and the weight should be light. POM polyoxymethylene resin plastic (Saigang) is a hard and dense material with a smooth and shiny surface, high strength and rigidity, good elasticity, and good wear resistance and wear resistance. Its mechanical properties are excellent, the specific strength can reach 50.5MPa, and the specific stiffness can reach 2650MPa, which is very close to metal. So it is more suitable to be used as a worm pair.

(2) Stress analysis of atomization generating device

The quality _G1 of the bottom plate can be obtained from the design size of the bottom plate and the density of the PVC profile:

G ₁ =0.9m×0.2m×3×10-3m×1.42kg/m ³ =0.76kg

The mass G ₂ of the water storage tank can be obtained from the design size of the water storage tank and the density of pp material:

G ₂ =π(22-1.82)×12×0.9g/cm ³ =26g

The mass of the water storage tank G ₃ when the water storage tank is full of water:

G ₃ =π1.82×12×1g/cm ³ =122g

The mass of the whole bottom plate device G=G ₁ +2G ₂ +2G ₃ =1.056kg

Please refer to Figure 12 for a simplified diagram of the force analysis of the base plate and the hook. Figure 12 shows the force situation when the connecting axis of the base plate and the horizontal direction of the hook form an angle θ. G is the gravity of the entire base plate, and F is the tension on the base plate in the direction of the connecting axis. F' is the resultant force of F and G, and it is also the driving force required by the worm gear. At this time F':

F'＝G/tan(θ)

From the gravity coefficient g=10kg/N, G=10.56N can be obtained

At this time, the torque (torque) M(F') of the force F' to the point O:

Since the sector gear part of the right connecting shaft is not easy to process into a semicircle, θ∈(10°-90°) is taken.

Fig. 13 is the situation when the connecting shaft of the base plate is 90° with the hook.

(3) Technical parameters of worm gear pair

1) Design according to the contact fatigue strength of the tooth surface

Because the mechanism requires good self-locking performance, the number of screw heads Z ₁ = 1 is taken, and when Z ₁ is taken as 1 according to the regulations, the number of worm gear teeth Z ₂ >40, and the transmission ratio i=Z ₂ /Z ₁ >40, so Z is taken ₂ = 42. The worm gear does not require a high speed, so the worm speed n ₁ = 30r/min is taken, and the worm wheel speed n ₂ = 5/7r/min is obtained from i = 42.

Worm design formula:

In the formula, T ₂ is the torque acting on the worm wheel (N/mm ³ );

K is the load factor K=1-1.3;

[σ] _H is the allowable contact stress of the worm gear (N/mm ² )

① Calculate the torque T2 acting on the worm wheel:

T2 is the torque of F' acting on point O in Figure 12, which is determined by the force analysis It can be seen that when the maximum torque is θ 10°:

② Determine the load factor K:

Load factor K, K=1.1 is taken because the load of this structure is stable and the sliding speed requirement is low;

③ Calculate the allowable contact stress of the worm gear:

[σ _H ]'——Basic allowable contact stress of the worm gear material, the material of the worm gear is POM engineering plastics, the basic allowable contact stress is 35% of the compressive strength of the POM material, [σ _H ]'=42.7Mpa.

N—Number of stress cycles N=60n ₂ jL _h , where n ₂ is the number of worm gear teeth; j indicates whether the motor rotates in one or two directions (1 for one direction, 2 for double); L _h is the design working time (365 days, 8 hour), when N>25×10 ⁷ , take N=25×10 ⁷ ; when N<2.6×10 ⁵ , take N=2.6×10 ⁵ .

To sum up

Look up Table 1 to get the standard modulus m and the diameter d1 of the worm pitch circle to be 1.6 and ₂₀ respectively.

Table 1 Modulus m, worm indexing circle diameter d ₁ and m ² d ₁ values

Pitch circle diameter d ₂ , d ₁ , center distance a and lead angle γ of worm gear and worm:

d ₁ =20

d ₂ =mz ₂ =1.6*42=67.2

2) Check according to the bending fatigue strength of the dedendum:

Calculate the equivalent number of teeth Look up Table 2 and get YFa=1.55.

Z _V Y _Fa Z _V Y _Fa ZV Y _Fa Z _V Y _Fa 20 1.98 30 1.76 40 1.55 80 1.34 twenty four 1.88 32 1.71 45 1.48 100 1.30 26 1.85 35 1.64 50 1.45 150 1.27 28 1.80 38 1.61 60 1.40 300 1.24

Table 2 Turbine profile coefficient

It can be seen from the table that [σ]’=20.68Mpa, then the allowable bending stress:

according to

Calculation formula of bending fatigue strength of tooth root of worm gear

Get σ＝1.1753＜[σ _F ]

Therefore, the root bending fatigue strength of the worm gear teeth is sufficient.

3) Dimensions of each part of worm gear

_Tactual =T·η=4000×0.33=1320(N·mm)>T ₂

Therefore, the motor meets the requirements.

(4) Design and selection calculation of ultrasonic atomization sheet

According to the design requirements, the air humidifier should meet the indoor use of 15m ² -35m ² , but since the national standard does not clearly stipulate the humidification capacity of the air humidifier in the 15m ² -35m ² room, it is often suitable for 15m ² -35m ² according to the market The humidification capacity of the indoor air humidifier is determined. The humidification capacity of the humidifier is 500ml/h (two left and right, one side 250ml/h).

The ultrasonic nebulizer adopts the design of cotton swab to absorb water, so the microporous atomizing sheet is selected.

Design size of absorbent cotton swab:

The outer diameter of the designed water storage cylinder is 40mm, the wall thickness is 2mm, and the length is 120mm, so the design size of the absorbent cotton is 115mm.

Two, filter water storage device

(1) Size of filter water storage device

The volume of the water storage layer is designed to be 10cm*5cm*9cm (length*width*height), the first layer of synthetic fiber filter layer is installed at a distance of 8cm from the bottom, and the second layer of activated carbon filter layer is installed at a distance of 7cm from the bottom to store water for the lower part Leave a design space of 10cm*5cm*6cm=300ml.

Considering that there should be about 300ml of water in the water storage place (for ozone sterilization), and the design goal stipulates that the atomization volume of the atomizer is 500ml/h, so the flow rate of the water inlet is set to 500ml, and the flow rate of the water outlet is 500ml. When the whole atomizer is running, first turn on the condensed water collection system and filter water storage system. When the water level monitoring sensor in the filter water storage system detects that the water level reaches 300ml, it sends a signal and then opens the water outlet to transport the water sterilized by ozone. to the atomizer.

(2) Calculation of the pipe diameter of the water inlet:

Assuming that the water in the water inlet pipe is full (that is, the maximum water intake), check hydraulics for the regulation of the tube velocity of the self-flowing condenser tube (the self-flowing tube means that the water in the tube flows freely under the action of gravity, and the pressure in the tube is the standard atmospheric pressure), and take The flow rate from the condensation pipe of the wall-mounted air conditioner indoor unit to the water inlet pipe is 0.1m/s. The flow rate, flow rate and pipe diameter of the water pipe have the following relationship:

Q ₁ =S ₁ *V ₁

Q ₁ --Inlet flow rate

S ₁ --Cross-sectional area of water inlet pipe, S=πr ²

V ₁ -- water inlet velocity, V＝0.1m/s

Therefore, the diameter of the water inlet is 1.4mm

Outlet pipe diameter calculation:

The water flow at the water outlet is not self-flowing, because there is a 4cm high hydraulic pressure in the tank, as shown in Figure 14.

At this time, the gravitational potential energy is converted into kinetic energy:

From Q ₂ =S ₂ *V ₂ , calculate r ₂ ≈0.6

Therefore, the outlet pipe diameter is 1.2mm

(3) Design and selection of ozone generator

According to the standard of the Ministry of Health for the application of ozone disinfection, the concentration required for water purification and disinfection is 0.1-10mg/L, the safe concentration in the air is 0.15ppm, and the half-life of ozone is about 20-30min when the water temperature is 10°C.

Choose an ozone generator with an ozone output of 10 mg/h, and stop the machine for 30 minutes to produce ozone for 30 minutes. Check whether the ozone concentration in the water storage and the ozone concentration in the air meet the national standard.

1) Check whether the water purification and disinfection requirements are met:

The amount of ozone produced by the ozone generator running for 30 minutes Wo ₃ =5mg

When the water storage place is full of water, it is 300ml

5mg of ozone is dissolved in 300ml of water according to the dissolution rate of 50%, then the ozone content in the water storage place at this time

Therefore, it meets the requirements for water storage and purification and disinfection.

2) Check whether it meets the air safety concentration requirements:

In the first chapter (1) of this paper, it is clearly stipulated that the applicable area of the air humidifier is 15m ² -35m ² , and the minimum area of 15m ² is now taken as the volume standard for checking and calculating the ozone concentration in the air.

Assuming that the height of the room is 3m, then the volume of the room of 15m2 is V=3*15=45m ³

The amount of ozone produced by the ozone generator running for 30 minutes Wo ₃ =5mg

The air ozone concentration Ko ₃ is calculated according to the uniform diffusion in the whole room:

Therefore, it meets the air safety concentration requirements.

3. Condensate collector

(1) Description of material selection for condensate collection system

Because the cooling and heating condensate collection system is to collect condensed water, it is required that the pipeline is non-toxic and the structure is stable under normal temperature and pressure, so pp material (polypropylene) is used, which is a non-toxic, odorless, tasteless milky white high Crystalline polymer with low density and light weight meets design requirements.

(2) Selection instructions for the water pump of the second condensate collector

The water pump of the second condensed water collector is mainly used for heating the external water of the outdoor unit of the air conditioner in winter, and pumps the water in the water tank of the second condensed water collector of the outdoor unit to the filtered water storage system.

According to the installation regulations of wall-mounted air conditioners, the installation height difference between indoor and outdoor units generally does not exceed 5m, so the head of the water pump should be greater than 5m to meet the needs of different installation height differences.

The flow rate of the filter water storage port is set to be 500ml/h in the design goal, so when selecting a water pump, the flow rate of the water pump should be greater than 500ml/h.
