Description
Technical field
The invention belongs to sprayer technical field, more particularly to electric micro-sprayer.
Background technology
Sprayer is widely used among people's daily life, such as kills insect, sterilization, beauty and make-up, washing, cleaning
Etc. occasion, the common sprayer of in the market has hand sprayer, high-pressure aerial fog agent tank, power spraye.Hand sprayer product
There are safety, energy-saving and environmental protection, can reuse, it has the disadvantage that jet length is near, it is impossible to continuous injection, expense when using
Strength and inconvenience.High-pressure aerial fog agent tank product has the advantages that convenient to use, and common kind has aerial fog pesticide, aerosol
Air freshener, aerosol cleaning agent, industrial aerosol releasing agent etc..The operation principle of high-pressure aerial fog agent tank product is using high steaming
Vapour pressure material is (such as：Fluorine chlorohydrocarbon, lower paraffin hydrocarbon, ethers) as propellant, surge in tank is come out, in addition cast
Agent is acted on without other.It has the disadvantage：Belong to inflammable and explosive dangerous goods, waste the energy, pollution environment, can not reuse to be disposable
Articles for use, use cost is higher, the advantage of both power spraye and hand sprayer and high-pressure aerial fog agent tank：Laborsaving, safety, section
Can, environmental protection, can reuse, comply with energy-conservation and the trend of Development of Environmental Protection, be the ideal product of substitution high-pressure aerial fog agent tank,
But, present electric micro-sprayer has that complicated, production cost is high, ineffective shortcoming, therefore is also difficult to
Substitute high-pressure aerial fog agent tank.
Retrieve Chinese Patent Literatures, the power spraye of the patent No. 200410062861.9, including motor, sliding tooth
Wheel, travelling gear, cam, cam connecting shaft, pump, check valve etc., its shortcoming：Complicated, production and assembly more inconvenience, production
Cost is high, a kind of vial-type electric micro-sprayer of the patent No. 200320114288.0 and 200620051396.3 vial-type electric atomizings
Device, its common drawback is：Because being fitted close between motor shaft and motor Simmer ring, frictional resistance is larger, causes the work of motor
Make electric current big, battery is short, inefficiency.
The content of the invention
The technical problem to be solved in the present invention is, simplify the structure of electric micro-sprayer, reduce motor shaft frictional resistance,
Reduce production cost and energy consumption, improving spray effect and operating efficiency, there is provided a kind of simple in construction, production and assembly are easy, cost
The electric micro-sprayer that low, spray effect is good, operating efficiency is high.
The present invention is for the technical scheme that uses of solution above-mentioned technical problem：
Electric micro-sprayer, including battery case lid, main body, motor and the pump housing are located in lower body part, body top
Container cover is spirally connected liquid container, and button is provided with the battery case lid, and the internal cavity of body top lays battery for battery compartment
Group, body top side, which has, installs nozzle assembly and nozzle cover on nozzle, nozzle, anti-watertight is provided between the main body and the pump housing
