Description

Technical Field

[0001] This field relates to spraying devices, and more particularly to a portable spraying device. Background Technology

[0002] Spraying devices have wide applications both indoors and outdoors in civil, industrial, and agricultural settings. By applying water mist into the air, they can increase humidity indoors, prevent dust from flying or static electricity from being generated, and also have a cooling effect when used with a fan. Outdoors, they can cause dust in the air to fall to the ground with the water mist, and can also moisturize and irrigate crops or flowers.

[0003] Typical spraying devices are fixedly installed on fans or at the site of use, occupying a large area and not being disassembled. When not in use, they affect the appearance of the fan or the site of use. If installed outdoors for a long time, the spraying device will be exposed to sunlight for a long time, which can easily accelerate the aging of the plastic components in the spraying device and reduce its service life.

[0022] To better understand the purpose, structure, and function of this utility model, a mobile spraying device of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Figure 1-5 The illustration shows the first embodiment of this utility model. The movable spray device of this embodiment includes a housing 1, which consists of a front cover 2 and a rear cover 7. The top surface of the front cover 2 has a first through hole 3, and the side surface has a second through hole 4. The first through hole 3 has an internal thread that matches the external thread of the nozzle 5 installed therein. The first through hole 3 and the nozzle 5 are fixedly connected by the thread. The nozzle 5 is a commercially available standard specification; the nozzle model and number of nozzles can be selected according to the desired atomization effect. A water quick connector 6 is fixedly installed in the second through hole 4. The water quick connector 6 can be connected to a tap water faucet via a matching connecting pipe. Both the water quick connector 5 and the matching connecting pipe are commercially available standard specifications. Tap water can flow into the housing 1 through the matching connecting pipe and the water quick connector 6.

[0024] The front cover 2 has a recessed internal space and an opening on its bottom surface. The opening has an internal thread that matches the external thread on the rear cover 7. The front cover 2 and the rear cover 7 are fixedly connected by the thread. To ensure the device's airtightness, a groove is provided between the internal thread and the outer surface of the rear cover 7, in which a sealing ring 8 is placed. After the front cover 2 and the rear cover 7 are fixedly connected by the thread, the sealing ring 8 is positioned between them, providing a leak-proof seal. The recessed internal space of the front cover 2 and the rear cover 7 form a receiving chamber, which is the receiving chamber of the housing 1. The receiving chamber has two through holes: a first through hole 3 fixedly connected to the nozzle 5 and a second through hole 4 fixedly connected to the water quick connector 6. The water quick connector 6 is the water inlet, and the nozzle 5 is the water outlet. Tap water enters the receiving chamber through the matching connecting pipe into the quick connector 5 and the second through hole 4. Under the water pressure, the tap water passes through the first through hole 3 and is atomized into a spray by the nozzle 5. Of course, to further ensure the sealing of the device, common sealing materials such as sealant or sealing tape can be applied at the connection between the first through hole 3 and the nozzle 5, the connection between the second through hole 4 and the water quick connector 6, and between the front cover 2 and the rear cover 7.

[0025] like Figure 5 , 6As shown, a cavity 9 is provided on the outside of the rear cover 7. A fixing hole 10 is provided inward at the bottom of the cavity 9, and the fixing hole 10 is provided with internal threads. The cavity 9 and the fixing hole 10 are independently provided on the outer surface of the rear cover 7 and are isolated from the accommodating chamber of the housing 1. A magnet 12 is provided in the cavity 9. The magnet 12 is annular. The magnet 12 is a commonly used metal or non-metal magnetic material that generates a magnetic force on magnetically sensitive materials, such as commonly used magnets or magnetic polymers. In this embodiment, a magnet is used. A screw 13 is provided at the center of the annular magnet 12. The size of the nut of the screw 13 is larger than the inner size of the annular center of the magnet 12. The nut of the screw 13 is locked on the outer surface of the magnet 12. The outer diameter of the screw shank is smaller than the inner size of the annular center of the magnet 12. The screw shank can pass through the annular center of the magnet 12 and match the internal thread of the fixing hole 10 through the external thread. The screw 13 fixes the magnet 12 in the cavity 9.

[0026] The rear cover 7 is also provided with a positioning hole 11. The inner wall of the positioning hole 11 is provided with internal threads. The positioning hole 11 is also independent of the outer surface of the rear cover 7 and isolated from the accommodating chamber of the housing 1. Hooks, screws, expansion bolts and other rod-shaped protrusions protruding from the surface of the object can be sleeved in the positioning hole 11. When the position of the movable spray device needs to be relatively fixed, the positioning hole 11 can be screwed onto the screw on the surface of the object to fix the positioning hole 11 to the screw. The connection between the movable spray device and the object is more stable and less susceptible to external interference.

[0027] In use, connect the water quick connector 6 to the tap using the matching connecting pipe. Position the movable spray device's rear cover 7 close to the center of the front grille of the floor fan. Since the center of the front grille is made of iron alloy, when the center of the front grille is within the magnetic field range of the magnet 12 fixed on the rear cover 7, the magnet 12 will be attracted to the center of the grille under the influence of the magnetic force. Turn on the tap. Tap water flows under pressure through the matching connecting pipe, through the water quick connector 6, and into the receiving chamber of the housing 1. Once the receiving chamber is full, the water flow is atomized into a mist by the nozzle 5 and sprayed out. With the tap on, the nozzle 5 continuously outputs water mist. Turn on the floor fan. The air from the floor fan blows through the front grille, and the water mist output by the nozzle 5 spreads rapidly in the direction of the airflow from the floor fan, which can increase air humidity, lower air temperature, and reduce dust. After use, turn off the tap. Apply a force to the movable spray device with your hand to move it away from the center of the front grille of the floor fan. When the force is greater than the magnetic force between magnet 12 and the center of the front grille of the floor fan, the movable spray device can be removed from the floor fan. Removing the movable spray device will not affect the normal use of the floor fan.

[0028] When the movable spray device requires relatively stable fixation, a screw with external threads can be installed on the surface of the fixed object. Align the positioning hole 11 on the rear cover 7 of the movable spray device with the screw, and rotate the movable spray device to make the positioning hole 11 and the screw threadedly connected, thereby stably installing the movable spray device on the surface of the fixed object. Connect the water quick connector 6 and the tap using the matching connecting pipe. Turn on the tap, and the tap water flows through the connecting sleeve and the water quick connector 6 under water pressure, entering the receiving chamber of the housing 1. After the receiving chamber is full of water, the water flows through the nozzle 5 and is atomized and sprayed out. When the tap is on, the nozzle 5 continuously outputs water mist. When water mist output is not needed, turn off the tap, and the spray will stop as the water pressure disappears. For disassembly, with the tap closed, separate the matching connecting pipe from the water quick connector 6, and then rotate the movable spray device until the positioning hole 11 separates from the screw.

[0029] Figure 6 This is a top view of the second embodiment of the present invention. The housing 1' is a one-piece molded plastic part. The housing 1' has a hollow accommodating chamber (not shown in the figure) inside. The housing 1' is provided with two through holes, which are respectively fixedly connected to the nozzle 5' and the water quick connector 6'. The nozzle 5' and the water quick connector 6' are connected to the hollow structure of the housing 1'. Tap water can enter the accommodating chamber of the housing 1' through the water quick connector 6', and is sprayed out after being atomized by the nozzle 5'. A protruding ring 14 is also fixedly connected to one side of the housing 1'. The protruding ring 14 can be suspended on hooks, nails, or other protrusions, with few restrictions on the size of the protrusions, applicable to many occasions, and convenient to use.

[0030] In use, connect the water quick connector 6 to the water tap using the matching connecting pipe. Align the protruding ring 14 on the movable spray device with the protrusion, suspending the ring 14 on the protrusion. Turn on the water tap, and tap water will flow from the tap, passing through the matching connecting pipe and the water quick connector 6' under water pressure, entering the hollow receiving chamber inside the housing 1'. Once the receiving chamber is full of water, the water flow will be atomized into a spray by the nozzle 5' under water pressure. After use, turn off the water tap, remove the movable spray device from the rod, and disconnect the matching connecting pipe and the water tap from the water quick connector 6'.

[0031] This portable spray device is particularly suitable for temporary or seasonal use in various situations. When used indoors in factories or homes, since the center of the front grille of a floor fan or industrial fan is typically made of iron or iron alloy, the portable spray device can be directly attached to the center of the grille. Installation and disassembly require no tools, making it very convenient. Due to the dry air, for temporary outdoor use, the portable spray device can also be hung or mounted on a protrusion. After use, the portable spray device and its connecting pipes can be disassembled and retrieved, avoiding the rapid aging caused by prolonged exposure to sunlight and extending the service life of the spray device and its connecting pipes. Furthermore, the portable spray device is small in size, occupies little space, and is easy to store.
