Description

Technical Field

[0001] The present invention relates to liquid spraying equipment, and in particular to a water sprayer. Background Art

[0002] The handheld water sprayer at least comprises a housing and a water valve arranged in the housing, wherein the water valve is equipped with a water valve switch. The housing of the handheld water sprayer in the prior art is a combined structure, which is fastened by screws. Fastening the housing by screws not only affects the hand feeling when using it and is easy to loosen, but also is not beautiful and is difficult to meet the aesthetic requirements of users. Summary of the invention

[0003] The technical problem solved by the present invention is that the handheld water sprayer uses screws to fasten the shell, which is not only easy to loosen, affecting the feel of use, but also unsightly and difficult to meet the aesthetic requirements of users.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a handheld sprinkler, comprising a shell, a water valve arranged in the shell, a water valve switch matched with the water valve, the water valve connecting a water inlet and a water outlet, parts between the water inlet and the water valve, and parts between the water valve and the water outlet, which together with the water valve constitute the internal structure of the sprinkler, the shell is provided with a water inlet giving way structure and a water outlet giving way structure, one side of the shell is an open structure, and the other side of the shell is a locking structure, the locking structure is connected to the open structure, the internal structure of the sprinkler is assembled into the shell as a whole through the open structure, and the locking member is assembled into the locking structure and connected to the internal structure of the sprinkler.

[0005] According to the above technical solution, the assembled internal structure of the water sprinkler is completely inserted into the shell through the open structure, and then the locking member cooperates with the locking structure of the shell, and the locking member is connected to the internal structure of the water sprinkler. In this way, the internal structure of the water sprinkler will not be withdrawn from the shell, and the internal structure of the water sprinkler is locked in the shell by the locking member, completing the assembly of the handheld water sprinkler.

[0006] The parts between the water inlet and the water valve, and the parts between the water valve and the water spout, can be water pipes, or can be a combination of a water pump and a water pipe. The parts where the water inlet is located are located in the water inlet yielding structure, and the parts where the water spout is located are located in the water spout yielding structure. The user operates the water valve switch to open the water valve, the water inlet is connected to the water spout, and water is sprayed out through the water spout.

[0007] As an option, the locking structure is a water inlet yielding structure, and the locking member is a water inlet joint. The water inlet yielding structure is located at the bottom of the shell, and after the internal structure of the sprinkler is integrally fitted into the shell, the water inlet joint is matched with the water inlet yielding structure, and the water inlet joint is connected to the part where the water inlet is located, so that the internal structure of the sprinkler is integrally locked in the shell.

[0008] As an option, the locking member is connected to the internal structure of the sprinkler by threaded connection.

[0009] As an option, a sealing ring is sleeved on the locking member, and the sealing ring seals the locking structure. Under the action of the sealing ring, the locking member and the locking structure of the housing are closely matched, which is beneficial to the internal structure of the sprinkler being stabilized in the housing.

[0010] As an option, an upper limit structure is provided in the shell, and the upper limit structure is against the upper limit auxiliary structure of the internal structure of the sprinkler, and the locking member located at the lower part of the shell has a downward pulling force on the internal structure of the sprinkler, and the downward pulling force causes the upper limit auxiliary structure to press against the upper limit structure. Under the upper and lower limit action of the locking member and the upper limit structure, the internal structure of the sprinkler is stabilized in the shell, and the stable cooperation between the internal structure of the sprinkler and the shell is achieved.

[0011] As an option, a convex guide structure is provided in the housing, and a concave guide structure capable of cooperating with the convex guide structure is provided on the internal structure of the sprinkler. When the internal structure of the sprinkler is completely inserted into the housing, the concave guide structure cooperates with the convex guide structure, so that the internal structure of the sprinkler can be smoothly and accurately assembled into the housing.

[0012] As an option, a positioning structure is provided in the shell, and a positioning convex portion capable of cooperating with the positioning structure is provided on the internal structure of the sprinkler, and the positioning convex portion and the positioning structure are arranged left and right. Under the left and right positioning action of the positioning convex portion and the positioning structure, the internal structure of the sprinkler is stabilized in the shell, so that the internal structure of the sprinkler and the shell are stably matched.

[0013] As an option, the housing is pistol-shaped, including a launcher at the top and a gripper at the bottom, the open structure extends from the launcher to the gripper, and the locking structure is located at the bottom of the gripper. The open structure can be located at the front side of the housing, and the entire internal structure of the sprinkler is inserted into the housing from front to back through the open structure, and then the locking piece is fitted into the locking structure from bottom to top and connected to the bottom of the internal structure of the sprinkler.

[0014] As an option, the front side of the housing is an open structure, the water valve switch is a push-type switch, one end of the push-type switch is hinged to the internal structure of the sprinkler, and the width of the open structure is greater than or equal to the width of the water valve switch. After the push-type switch is connected to the internal structure of the sprinkler, the internal structure of the sprinkler is inserted into the housing from front to back through the open structure, and then the locking member is fitted into the locking structure from bottom to top and connected to the bottom of the internal structure of the sprinkler, and the push-type switch protrudes forward from the open structure.

[0015] The handheld sprinkler of the present invention does not fasten the shell by locking screws, but after the internal structure of the sprinkler is installed in the shell as a whole, it is locked with a locking piece to complete the assembly. Moreover, the locking piece used is a water inlet joint commonly used in sprinklers, and no additional parts are required. In this way, the sprinkler is easy and quick to assemble, the structure of the assembled sprinkler is stable, and there is no threaded connector on the shell, which is not only conducive to improving the user's hand feel, but also beautiful.
