Abstract
Description
Technical Field
[0001] This utility model relates to the field of water-spraying wiper blade technology, and in particular to a water-spraying connector assembly with a one-way valve fixed on the wiper arm. Background Technology
[0002] The existing one-way valve of the integrated wiper arm is far from the water outlet, resulting in a slow response in water spray speed. Moreover, the existing one-way valve and connector assembly of the existing wiper arm are designed separately, requiring two fixed installation positions, which is complicated and costly. Utility Model Content
[0003] The technical problem to be solved by this utility model is to address the issues of slow water spray speed and complex installation of existing integrated wiper arm water spray wiper blades, and to provide a water spray connector assembly with a one-way valve that is fixed to the wiper arm with a one-way valve that is closer to the water outlet and has a simple installation method.
[0004] The technical problem to be solved by this utility model can be achieved through the following technical solution:
[0005] A washer fluid connector assembly with a one-way valve, fixed to a wiper arm, includes:
[0006] A connector assembly; the connector assembly has at least one channel and at least one water inlet connector is provided at one end of the connector assembly and at least one water outlet connector is provided at the other end; the water inlet connector and the water outlet connector are connected to both ends of the channel;
[0007] At least one one-way valve, said one-way valve being disposed within the channel; characterized in that,
[0008] A slot is provided on at least one side of the bottom of the connector assembly, and the claw on the scraper arm is inserted into the slot to lock the connector assembly.
[0009] In a preferred embodiment of the present invention, a claw inlet is provided at one end of the card slot, and the claw is introduced into the card slot through the claw inlet.
[0010] In a preferred embodiment of the present invention, an inlet structure and a limiting structure are provided at the bottom of the claw inlet. The inlet structure guides the claw into the slot, and the limiting structure restricts the claw within the slot.
[0011] In a preferred embodiment of this utility model, the inlet structure is an inclined surface, and the limiting mechanism is a surface perpendicular to the axis of the flow channel.
[0012] In a preferred embodiment of the present invention, the guiding structure and the limiting structure are disposed on a protrusion, wherein the guiding structure is disposed on the side of the protrusion facing away from the slot, and the limiting structure is disposed on the side of the protrusion facing the slot.
[0013] In a preferred embodiment of this utility model, the connector assembly includes a connector assembly body, the water outlet connector is integrally formed on the connector assembly body, the water inlet connector is inserted into the water inlet connector insertion hole of the connector body, and the water inlet connector insertion hole is connected to one end of the channel; the valve plug in the one-way valve blocks the water outlet end of the water inlet connector under the action of the spring, and after the water pressure overcomes the force of the spring, the valve plug in the one-way valve opens the water outlet end of the water inlet connector.
[0014] Due to the adoption of the above technical solution, the one-way valve of this utility model is located inside the connector assembly and very close to the water outlet connector, resulting in a fast water spray speed response. Furthermore, the water spray connector assembly with one-way valve uses the claws on the scraper arm and the slots on the connector assembly to directly engage with the scraper arm, simplifying the installation process.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] See Figures 1 to 5 The figure shows a washer fluid connector assembly with one-way valves fixed to a wiper arm, comprising: a connector assembly 100 and two one-way valves 200.
[0022] The connector assembly 100 includes a connector assembly body 110, a pair of inlet connectors 120, and a pair of outlet connectors 130. The connector assembly body 110 has two parallel flow channels 111 and two inlet connector insertion holes 112. The outlet connectors 130 are integrally formed on the connector assembly body 110 and communicate with one end of the flow channel 111. The two inlet connector insertion holes 112 are respectively communicated with the other end of the flow channel 111. The two inlet connectors 120 are respectively inserted into the two inlet connector insertion holes 112.
[0023] Two one-way valves 200 are respectively installed in two flow channels 111. The valve plug 210 in the one-way valve 200 blocks the outlet end of the water inlet connector 120 under the action of the spring 220. After the water pressure overcomes the force of the spring 220, the valve plug 210 in the one-way valve 220 opens the outlet end of the water inlet connector 120. Placing the one-way valve 200 in the flow channel 111 of the connector assembly 100, closer to the water outlet connector 130, can make the water spray speed respond quickly.
[0024] Another feature of this utility model is that a slot 140 is provided on each side of the bottom of the connector assembly body 110, and a claw inlet 141 is provided at one end of the slot 140, so that the claw 310 on the scraper arm 300 is guided into the slot 140 from the claw to the inlet 141 and locked to the connector assembly 100.
[0025] To facilitate the insertion of the jaw 310 into the slot 140 and to confine the jaw 310 within the slot 140, an insertion structure 142 and a limiting structure 143 are provided at the bottom of the jaw inlet 141. The insertion structure 142 is an inclined surface, and the limiting structure 143 is a surface perpendicular to the axis of the flow channel 111. The insertion structure 142 and the limiting structure 143 are disposed on a boss 144, wherein the insertion structure 142 is disposed on the side of the boss 144 facing away from the slot 140, and the limiting structure 143 is disposed on the side of the boss 144 facing the adjacent slot 140. The insertion structure 142 serves to insert the jaw 310 into the slot 140, and the limiting structure 143 serves to confine the jaw 310 within the slot 140.
