A water jet wiper insert with a one-way valve

Abstract

This utility model discloses a water spray scraper connector with a one-way valve, comprising: a connector, a plug, and a one-way valve. One end of the connector has a first insertion hole for connecting to a fluid element in the water spray scraper. Fluid is injected into the fluid element and fed into the channel of the baffle plate through the fluid element's distribution mechanism, then sprayed out through the spray holes on the baffle plate. The other end of the connector has a second insertion hole for connecting to a water inlet connector. A one-way valve mounting hole is also provided within the connector, located between the first and second insertion holes and communicating with them. One end of the plug is inserted into the second insertion hole, and the other end is connected to the water inlet pipe in the water spray scraper. A one-way valve is installed in a corresponding one-way valve mounting hole and is used to prevent water or cleaning fluid from returning from the first insertion hole to the second insertion hole. This utility model incorporates a one-way valve within the connector, which both prevents backflow and connects the water pipe to the fluid element.

Description

Technical Field

[0001] This utility model relates to the field of water spray blade technology, and in particular to a water spray blade connector with a one-way valve. Background Technology

[0002] Most commercially available windshield washer blades or wiper arms connect the water supply pipe to the inlet via a connector. This necessitates an additional one-way valve on the wiper arm for backflow prevention. This method results in more parts and a more complex assembly process. Utility Model Content

[0003] The technical problem this invention aims to solve is that existing technologies require an additional one-way valve component on the scraper arm for check valve operation. This approach results in numerous parts and a cumbersome assembly process. This invention provides a water spray scraper connector with an integrated one-way valve to simplify the assembly process.

[0004] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0005] A water spray scraper connector with a one-way valve, characterized in that it comprises:

[0006] The connector has a first insertion hole at one end that connects to a fluid element in a water spray blade. The first insertion hole injects fluid into the fluid element and, through the distribution input of the fluid element, into the channel of the deflector, and then sprays it out through the spray holes on the deflector. The other end of the connector has a second insertion hole that connects to a water inlet connector. The connector also has a one-way valve mounting hole located between the first insertion hole and the second insertion hole, and communicating with the first insertion hole and the second insertion hole.

[0007] A connector, one end of which is inserted into a second socket, and the other end of which is connected to the water inlet pipe in the water spray blade;

[0008] A one-way valve is installed in each one-way valve mounting hole and is used to restrict the return of water or cleaning fluid from the first socket to the second socket.

[0009] In a preferred embodiment of the present invention, one end of the connector is inserted into the second socket through elastic deformation.

[0010] In a preferred embodiment of this utility model, the one-way valve includes a valve core and a spring. Under the action of the spring, the valve core blocks the water outlet of the connector. When water enters the connector, the water pressure overcomes the elastic force of the spring and pushes open the valve core, opening the water outlet of the connector.

[0011] In a preferred embodiment of this utility model, the one-way valve mounting hole is a stepped hole with a first diameter, a second diameter, and a third diameter. The first diameter has the largest diameter, the second diameter has the second largest diameter, and the third diameter has the smallest diameter. The first diameter is connected to the second insertion hole, and the third diameter is connected to the first insertion hole. The valve core is T-shaped and has a large-diameter shaft and a small-diameter shaft. The large-diameter shaft is slidably disposed in the first diameter, and the small-diameter shaft is slidably disposed in the second diameter. The spring is sleeved on the small-diameter shaft and located in the second diameter. One end of the spring abuts against the end face of the large-diameter shaft adjacent to the small-diameter shaft, and the other end of the spring acts on the end face of the third diameter adjacent to the second diameter. A first water passage groove and a second water passage groove are provided on the shaft surfaces of the large-diameter shaft and the small-diameter shaft, which are interconnected. When the outlet end of the connector is opened, the water or cleaning fluid flows into the first insertion hole through the first water passage groove and the second water passage groove.

[0012] By adopting the above technical solution, this utility model sets a one-way valve in the connector, which can both prevent backflow and connect the water supply pipe to the fluid element, thus achieving the purpose of simplifying the assembly process of the water spray blade.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] See Figures 1 to 7The water spray blade connector with a one-way valve shown in the figure includes: a connector 100 and two connectors 200. One end of the connector 100 is provided with two holes 110 (the aforementioned first holes) that are connected to the fluid element 300 in the water spray blade. The other end of the connector 100 is provided with two holes 120 (the aforementioned second holes) that are connected to the water inlet connector. The two holes 110 inject fluid into the fluid element and, through the distribution of the fluid element, input it into the channels of the baffles 310 and 320 respectively, and spray it out through the water spray holes 311 and 321 on the baffles 310 and 320.

[0022] One end of each of the two connectors 200 is inserted into the socket 120 in an elastic deformation manner, and the other end of each of the two connectors 200 is connected to the water inlet pipe 400 in the water spray blade.

[0023] The connector 100 also includes one or two one-way valve mounting holes 130. Each one-way valve mounting hole 130 is located between each socket 110 and each socket 120 and communicates with the socket 110 and the socket 120. The one-way valve mounting hole 130 is a stepped hole with a first diameter 131, a second diameter 132 and a third diameter 133. The first diameter 131 has the largest diameter, the second diameter 132 has the second largest diameter, and the third diameter 133 has the smallest diameter. The first diameter 131 is connected to the socket 120, and the third diameter 133 is connected to the socket 110.

[0024] Two check valves 500 are respectively installed in two check valve mounting holes 130, and the check valves 500 are used to restrict the return of water or cleaning fluid from the socket 110 to the socket 120.

[0025] Each one-way valve 500 includes a valve core 510 and a spring 520. When no water enters, the valve core 510 blocks the water outlet of the connector 220 under the action of the spring 520. When water enters the connector 220, the water pressure overcomes the elastic force of the spring 520 and pushes open the valve core 510, opening the water outlet of the connector 220.

[0026] The valve core 510 is T-shaped and has a large-diameter shaft 511 and a small-diameter shaft 512. The large-diameter shaft 511 is slidably disposed in the first bore 131, and the small-diameter shaft 512 is slidably disposed in the second bore 132. The spring 520 is sleeved on the small-diameter shaft 512 and located in the second bore 132. One end of the spring 520 abuts against the end face of the large-diameter shaft 511 adjacent to the small-diameter shaft 512, and the other end of the spring 520 acts on the end face of the third bore 133 adjacent to the second bore 132.

[0027] A first water passage groove (not shown in the figure) and a second water passage groove (not shown in the figure) are provided on the shaft surfaces of the large diameter shaft 511 and the small diameter shaft 512. When the water outlet end of the connector 200 is opened, water or cleaning fluid flows into the socket 110 through the first water passage groove and the second water passage groove.
