The nozzle assembly 200 is arranged on the top of the tank body 100, and the liquid storage tank 300 extends into the interior of the tank body 100; the nozzle assembly 200 can be connected to the tank body 100 by conventional installation methods such as threaded connection.

[0033] The top cover assembly includes a protective cover 401 and a slide plate inner cover 402. The protective cover 401 is connected to the nozzle assembly 200 by threaded connection or clamping. A slide groove 405 is also provided on the nozzle assembly 200. The slide plate inner cover 402 is provided in the slide groove 405, and the slide plate inner cover 402 slides along the slide groove 405.

[0034] The protective cover 401 is provided with a spray port and a pressing port, and the spray port and the pressing port are symmetrically arranged. The nozzle assembly 200 includes a spray port 201 and a pressing portion 202, the position of the spray port 201 corresponds to the position of the spray port, and the position of the pressing portion 202 corresponds to the position of the pressing port.

[0035] The pressing port is an arc-shaped structure. The purpose of setting the arc-shaped pressing port is to facilitate the distinction from the spray port and avoid accidental injury to personnel due to holding the device upside down during use.

[0036] The slide plate inner cover 402 is arranged inside the protective cover 401 and is a symmetrical structure. The size of the slide plate inner cover 402 is larger than the size of the spray port and the pressing port, that is, the slide plate inner cover 402 needs to completely cover the spray port and the pressing port in the closed state.
