Description

Garden spray gun with replaceable water nozzle

The present invention relates to a gardening water spray gun structure which can replace the water spout head according to the needs of use.

The water spray gun can directly control the water output and the shape of the water spray by the components at the water spraying place. Therefore, it is widely used in gardening spraying or vehicle cleaning. The most common water spray guns in the market today are shown in Figure 12. The water spray gun (60) mainly has a gun body (61), the front end of the gun body (61) is provided with a rotatable water spray head (62), the water spray head (62) is integrally formed with one or more water spray ports (621) , When the water spray head (62) is rotated, the shape of these water spray ports (621) can be transformed to achieve the effect of changing the water output and the shape of the spray. The rear end of the gun body (61) is provided with a can A pressing handle (63) for pressing against is used to control the opening and closing of the water source through whether the pressing handle (63) is pressed or not.

However, the above-mentioned conventional structure still has the following problems in practical application: (1) The water spray port (621) is integrally formed on the water spray head (62), so the shape of the water splash is different from that of the water spray head (62). The rotation sequence of the spray changes will be rigidly set before the water spray gun (60) leaves the factory, so that consumers cannot change the shape and rotation sequence of the spray according to their needs or preferences, and the convenience of use is not good. , and cannot achieve the effect of adapting to human conditions; (2) The water spout (621) is integrally formed on the water spout (62), so when the water spout (621) is damaged or blocked, Therefore, it is impossible to individually replace the water spray port (621), and the entire water spray head (62) and even the entire water spray gun (60) need to be directly replaced, which is wasteful in use.

Therefore, the inventor of the present invention has considered the idea of creation in view of this, and has designed it with years of experience. After many discussions and sample tests, and many revisions and improvements, the present invention is launched.

The water spray head of the conventional water spray gun is integrally formed with more than one water spray port, so that the water spray port cannot be replaced independently, which is the technical problem to be solved.

The gardening water spray gun with replaceable water nozzles of the present invention comprises: a water spray gun body, a water guide cover, at least one first water nozzle, at least one second water nozzle and a water nozzle seat, wherein the water spray gun The main body has a handle part and a barrel part which are connected to each other. A set of flanges is arranged on the outer periphery of the front of the barrel part, and a guide tube and a locking post are arranged inside. The guide tube is used to conduct the handle. The handle part is connected to a water source, so that the water source can be sent into the guide pipe through the handle part and then sprayed forward, and the water source can be set on the gun barrel when in use. The locking post in the center of the inside of the barrel is protruding from the front edge of the barrel. The water guide cover is provided with a middle hole, a first through hole, a second through hole and at least one third through hole. The first through hole, the second through hole and the third through hole are evenly arranged on the outside of the middle hole, so that the first through hole, the second through hole and the first through hole protruding from the front end surface of the water guide cover are respectively formed. A water outlet chamber and a second water outlet chamber are connected to each other, and the middle hole is used to provide the locking post to pass through, so that the water guide cover can be pivoted in the form that its rear end surface can abut the front end edge. On the water spray gun body, it can be operated through the water guide cover. The design of rotation enables the guide tube to be aligned with the first passage hole, the second passage hole or a third passage hole, and the front ends of the first water outlet chamber and the second water outlet chamber are connected to each other. The front end of the first water outlet chamber can be installed with a water outlet mesh plate. Both the first water outlet nozzle and the second water outlet nozzle have a cylindrical body. The front end of the cylindrical body is provided with different The water spray hole is in the shape of a water splash, and the outer periphery of the water inlet end at the rear end protrudes with a retaining edge for limiting the position. hole and at least one third set of holes, the inner walls of the first set of holes, the second set of holes and the third set of holes are all provided with a stepped portion, when the first water outlet nozzle and the second water outlet nozzle are respectively put into the first When the second set of holes and the third set of holes are inside, the blocking edge and the stepped portion can be mutually restrained, so that the first water outlet nozzle and the second water outlet nozzle can only protrude from the water outlet at their front ends. The seat cannot be pulled forward, so the coupling hole is used to provide the locking post for insertion, and then a bolt is used to lock the locking post to pivot the water outlet seat to the water spray. When the sleeve of the gun body is on the sleeve, the water guide cover can be covered by the water outlet seat, and the front end face of the water guide cover can be approached, so that the stepped portion and the front end of the first water outlet chamber, The stepped portion and the front end of the second water outlet chamber respectively clamp the water outlet mesh plate and the first water outlet nozzle, and the second water outlet is provided by the front end face of the water guide cover with the third through hole. The rear ends of the sprinklers are held against each other one by one, and because the first and second water outlet chambers protruding from the front end surface of the water guide cover are respectively sleeved into the first set of holes and the second set of holes, the When the water outlet seat is combined, the two positions can be used to engage and fasten at the same time, so that the water outlet seat and the water guide cover can move at the same time, so that when the water outlet seat rotates, it drives all the water heads together. The water guide cover is rotated, and the water outlet head seat can be disassembled again, so that the water outlet head seat and the water guide cover can be separated smoothly. The water spray head can be replaced with different spray shapes, so that the use of the garden spray gun can be more flexible. In addition, it is more suitable for people's conditions; thus, it can constitute the gardening water gun with the replaceable water nozzle.

(1) The gardening water spray gun of the present invention can replace the water outlet nozzle, the type and rotation sequence of the first water outlet nozzle and the second water outlet nozzle can be replaced or changed by the consumer, so that the use of the garden water spray gun can be changed. Flexible and flexible, and more adaptable to individual conditions.

(2) The horticultural water spray gun of the present invention can replace the water outlet nozzle, when the first water outlet nozzle and the second water outlet nozzle are damaged or blocked, only the first water outlet nozzle or the second water outlet nozzle needs to be replaced individually, The spraying can be re-provided, so that the use of the gardening water gun can be more economical and environmentally friendly.
