Specific embodiment
Embodiment 1
According to fig. 1 to fig. 6, a kind of water gun described in the present embodiment includes the front housing being sealedly and fixedly connected
Body 1 and back casing 2.
The front end of the procapsid forms spray head 13, forms front handlebar portion 11, remote holder below the procapsid rear end
The forward upper in portion is formed circular rod aperture 14, is located at before being formed below rod aperture in the front handlebar portion
Partition 12.
Form rear-handle portion 21 below the back casing, rear-handle portion rear end inner wall correspond to the position of rod aperture at
Type has water entering section 23, is located at below water entering section in the rear-handle portion and forms rear bulkhead 22, the back casing upper end forms
Water filling port 24 is connected with a cock body 4 on water filling port.
A complete hand handle is constituted after the front handlebar portion and the assembly of rear-handle portion.
The water entering section includes the cylindrical spring location division 231 and connection for being molded over rear-handle portion rear end inner wall
In the water jacket 232 of the circular tube shaped of spring location division front end, the front of the water jacket uniformly forms water inlet along axial direction
233。
The rear bulkhead and front baffle are tightly connected；It is located above front baffle and rear bulkhead in the procapsid and back casing
Form water storage cavity.
The pump housing 5 of flexible rubber or plastic material, the pump housing packet are installed between the rod aperture and water entering section
Integrally formed slide bar portion 51, and bellows portion 52 that can be axially retractable are included, the pump housing side wall is located at slide bar portion
Position between bellows portion forms water outlet connector 53, and the pump housing side wall is located at water outlet connector close to the one of bellows portion
Side forms spring collar 54.
The water outlet connector is connected with outlet pipe 7, and the outlet pipe other end is connect with spray head；Slide bar portion from-inner-to-outer is worn
It crosses rod aperture and is slidably connected with rod aperture sealing；The bellows portion rear end is slidably located in the water jacket, institute
It states to be located between spring collar and spring location division outside bellows portion and is arranged with spring 6.
The slide bar portion is hollow pipe structure, and slide bar portion internal diameter is less than the internal diameter of bellows portion, the slide bar portion
On be plugged with a pressing lever 3 from outer to inner, the pressing lever outer end forms press head 32, and pressing rod rear end periphery forms
More than two clamps 31, after the pressing lever is packed into slide bar portion, the clamp is engaging in the inner end in slide bar portion.
By ultrasonic bonding between the procapsid and back casing, the pump housing, spring and outlet pipe procapsid, after
Respective corresponding position is packed into before case weld.
It is that interference is mating between the outlet pipe and water outlet connector, spray head.
When the present invention assembles, first outlet pipe is connected on the pump housing, then the outlet pipe other end is connected on spray head, is connect
The pump housing be installed on procapsid, pressing lever is then installed, followed by installation spring, while back casing is buckled, is then surpassed
Sound wave welding, finally loads onto cock body, in total 8 steps, at least five component and installation procedure is reduced than originally, reduces
Required number of molds, cost of labor are significantly reduced.
The working principle of the invention be it is such, when pressing pressing lever, the bellows portion rear end of the coupled pump housing
It moving backward, when the rear end of bellows portion offsets with spring location division, water inlet is fully located within bellows portion, with
Pressing lever continues to press, and bellows portion generates contraction, and then the water in bellows portion is sprayed from spray head；When release is to pressing lever
Pressing when, the bellows portion of the pump housing extends under selfer power and the effect of spring-return power, and air pressure declines in bellows portion,
A small amount of air is inhaled into the pump housing from spray head outer outlet pipe, and after bellows portion reinstatement, bellows portion rear end exists
Continue forward slip along water jacket under the effect of spring-return power, until water inlet exposes out of bellows portion, pumps intracorporal sky
Gas is spilt into water storage cavity under buoyancy from water inlet, and the water in water storage cavity then enters from the inlet in the pump housing.
There are certain frictional force between the water jacket outer wall and bellows portion rear end, so that wave when unclamping pressing lever
Line pipe portion first extends, and then end is slided further along water jacket thereafter.After the length of the water jacket at least guarantees bellows portion
End will not be detached from it.When pressing pressing lever initial stage, water inlet is in the conductive state, and pumping intracorporal part water can be from water inlet
Mouth is reversed to be overflowed, and water is just then from spray head ejection when water inlet is covered by bellows portion, so every time from spray head ejection
Water is less, and the time that can be played after water filling every time is longer.
Embodiment 2
In conjunction with shown in Fig. 7 to Fig. 9, the present embodiment makes further improvement on the basis of embodiment 1: after the back casing
End is spherical or ellipsoidal shape, the cock body are integrally in the infundibulate being adapted with back casing rear end shape, fills in
The inner wall of body forms the plug body part 41 that connection is matched with water filling port 24；The bottom of the cock body forms intubation portion 42, intubation
The outer diameter in portion can match grafting with water filling port, and intubation portion side wall forms a vent grooves 421, the cock body outer wall
Periphery positioned at intubation portion also uniformly forms ventilatory support column 422.When the water in hydraulic giant water storage cavity, which is finished, to be needed to add water, only
Cock body lower end is started toward hydraulic giant back upper place, plug body part can be made to be separated from from water filling port, inserts intubation portion after removing cock body
Onto water filling port, that is, it is convenient to carry out hydraulic giant plus water, the vent grooves makes to be in communication with the outside in hydraulic giant, when guaranteeing to add water
Air in water storage cavity can be discharged from vent grooves, and the ventilatory support column contacts cock body outer wall with water filling port, guarantee
Vent grooves are not blocked.
