Description

Technical Field

[0001] This invention relates to the field of automotive windshield cleaning, and in particular to a heating nozzle for automotive hoods. Background Technology

[0002] In cold weather, snow and frost easily accumulate on car windshields, obstructing the driver's vision. Windshield washer fluid is needed to clean them. However, traditional windshield washer fluids are prone to freezing in low temperatures, causing the cleaning function to fail and potentially damaging the system. Existing heating devices are either complex and bulky or have low heating efficiency, failing to heat the washer fluid quickly and effectively, thus affecting the convenience and safety of using the car in cold weather. Therefore, there is an urgent need for an integrated heating nozzle to solve these problems. Summary of the Invention

[0003] In order to reduce the overall space occupied and improve the heating effect, thereby improving the convenience and safety of automobiles in cold weather, this application provides a car hood heating nozzle.

[0004] This application provides a car hood heating nozzle, which adopts the following technical solution:

[0005] A car hood heating nozzle includes a carrier and a nozzle ball. One end of the carrier has a water outlet and the other end has a water inlet pipe. The nozzle ball is installed at the water outlet. A water inlet channel is provided in the carrier between the water outlet and the water inlet pipe. A receiving groove is provided in the carrier, extending from the water outlet to the water inlet pipe. A heating element for heating within the receiving groove is installed on the carrier.

[0006] By adopting the above technical solution, when the car needs to use the nozzle in cold weather, the heating element is activated, and cleaning fluid is added to the water inlet channel through the water inlet pipe. Then, it is sprayed out from the nozzle ball at the water outlet. During this process, due to the action of the heating element, heat is transferred to the water inlet channel and the water outlet to heat the cleaning fluid and prevent it from solidifying inside the nozzle. With heating, the nozzle has fewer parts and a compact overall installation layout, which greatly reduces the overall space occupied and ensures effective and concentrated heat transfer. In addition, since the receiving groove for installing the heating element extends from the water outlet to the water inlet pipe, the cleaning fluid can be heated throughout its entire flow process within the nozzle, improving the heating effect and thus enhancing the convenience and safety of using the car in cold weather.

[0007] Preferably, the heating element includes a thermistor and a male connector for plugging into a female terminal of an automotive wiring harness. The thermistor is installed in the receiving groove, and the leads of the thermistor are electrically connected to the terminals of the male connector.

[0008] By adopting the above technical solution, in actual use, the male connector is first connected to the female terminal of the car power system, which can then supply power to the thermistor, causing the thermistor to heat up and thus heat the cleaning fluid entering the nozzle.

[0009] Preferably, a thermally conductive adhesive layer is provided in the receiving chamber, and the thermistor is located within the thermally conductive adhesive layer.

[0010] By adopting the above technical solution, when the thermistor heats up, the heat can be conducted efficiently and evenly through the thermally conductive adhesive layer, reducing heat loss and improving heating efficiency. During installation, the thermistor is installed first, and then the thermally conductive adhesive is poured into the receiving chamber to complete the installation of the heating element, which is convenient.

[0011] Preferably, the outer wall of the carrier is provided with a plug groove communicating with the receiving groove, the male connector is provided with a plug, and the plug is inserted into the plug groove; the plug is provided with a limiting member for limiting the plug to be in the plug groove.

[0012] By adopting the above technical solution, the male connector is directly inserted into the socket through the plug and then restricted by the limiting component, so that the nozzle components are integrated into a whole to form an integrated heating nozzle. The overall structure is compact after assembly, which makes the heat conduction very concentrated and improves the heating efficiency.

[0013] Preferably, the limiting member includes a deformation block and a limiting block. One end of the deformation block is elastically connected to the plug, and the other end extends away from the male connector and is a free end. The limiting block is disposed on the side of the deformation block facing the plug groove. An inclined guide surface is provided at the end of the limiting block near the bottom of the plug groove. The carrier is provided with a limiting hole communicating with the outside of the carrier in the groove wall of the plug groove, and the limiting block is engaged with the limiting hole.

[0014] By adopting the above technical solution, when the male connector is inserted into the socket, the deformation block is first deformed by the guiding action of the inclined guide surface. Then, when it is inserted to the position corresponding to the limiting block and the limiting hole, the deformation block can be reset so that the limiting block is locked into the limiting hole, thus limiting the male connector. This makes installation convenient and efficient. When the male connector needs to be removed, since the limiting hole is connected to the outside of the carrier, the limiting block can be moved directly through the limiting hole to deform the deformation block and allow the connector to leave the socket smoothly.

[0015] Preferably, a branch pipe is provided on the carrier near the water inlet pipe, and the two ends of the branch pipe are respectively connected to the water inlet channel and the outside of the carrier, and a plug ball is provided inside the branch pipe.

[0016] By adopting the above technical solution, in order to facilitate demolding during the injection molding process of the carrier, a branch pipe connected to the outside of the carrier will be left. Therefore, in order to prevent the cleaning fluid from flowing out of the branch pipe, the branch pipe is blocked by a plugging ball.

[0017] Preferably, it also includes a wire, one end of which is electrically connected to the lead of the thermistor and the other end of which is electrically connected to the terminal of the male connector.

[0018] By adopting the above technical solution, the male connector can be directly led out through the wire according to the actual use scenario, and the installation position of the male connector can be arranged in a more suitable position, thereby improving applicability.

[0019] Preferably, a positioning groove is provided in the receiving groove, and the thermistor is snapped into the positioning groove.

[0020] By adopting the above technical solution, the installation position of the thermistor can be made more stable and accurate, reducing the possibility of the thermistor shifting when thermally conductive adhesive is poured into the receiving chamber.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. When the car needs to use this nozzle in cold weather, the heating element is activated, and the cleaning fluid is added to the water inlet channel through the inlet pipe. Then, it is sprayed out from the nozzle ball at the outlet. During this process, due to the action of the heating element, heat is transferred to the water inlet channel and the outlet, heating the cleaning fluid and preventing it from solidifying inside the nozzle. With heating, the nozzle has fewer parts and a compact overall installation layout, which greatly reduces the overall space occupied and also ensures effective and concentrated heat transfer.

[0023] 2. The receiving groove for installing the heating element extends from the water outlet to the water inlet pipe, allowing the cleaning fluid to be heated throughout its entire flow process within the nozzle, thus improving the heating effect and enhancing the convenience and safety of the vehicle in cold weather.

[0024] 3. When installing this nozzle, the installation sequence is: install the nozzle ball, install the plug ball, install the thermistor, apply thermally conductive adhesive, and install the male connector terminal. This makes installation convenient and efficient. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses a heating nozzle for an automobile hood.

[0035] Example 1

[0036] Reference Figure 1 and Figure 2The car hood heating nozzle includes a carrier 1, a nozzle ball 2, and a heating element 3. One end of the carrier 1 has a water outlet 11, and the other end has a water inlet pipe 12. The nozzle ball 2 is installed at the water outlet 11 and is a fan-shaped spray nozzle ball 2, consistent with the spray structure described in patent application number CN211412382U, and will not be described further here. A water inlet channel 13 is provided inside the carrier 1 between the water outlet 11 and the water inlet pipe 12, and the water inlet pipe 12 is connected to a water supply pipe 4. The water supply pipe 4 is used to connect the water inlet pipe 12 to the car's cleaning fluid tank; thus, the cleaning fluid enters the nozzle from the water inlet pipe 12 through the water supply pipe 4, and then flows to the water outlet 11 through the water inlet channel 13, and is sprayed out in a fan shape by the action of the nozzle ball 2; a receiving groove 14 is provided in the carrier 1, which extends from the water outlet 11 to the water inlet pipe 12, and the heating element 3 is used to heat the water in the receiving groove 14, so that the cleaning fluid entering the nozzle is heated throughout the entire flow process.

[0037] Reference Figure 2 The heating element 3 includes a thermistor 31 and a male connector 32. The thermistor 31 is fixedly installed in the receiving groove 14 near the discharge port. A thermally conductive adhesive layer 33 is provided in the receiving groove 14. The thermistor 31 is located in the thermally conductive adhesive layer 33, which enables efficient and uniform heat conduction, reduces heat loss, and improves heating efficiency. The carrier 1 is located at the same end as the water inlet pipe 12 and at the position corresponding to the receiving groove 14, and a plug groove 15 is provided. The plug groove 15 is connected to the receiving groove 14. The male connector 32 is used to plug into the female terminal of the automotive wiring harness. One end of the male connector 32 has an integrally formed plug 34, which is plugged into the plug groove 15. The plug of the male connector 32 is electrically connected to the lead wire of the thermistor 31. This forms an integrated heating nozzle, and the overall structure is compact after assembly.

[0038] Reference Figure 3 and Figure 4The connector 34 is equipped with a limiting member for restricting the connector 34 within the insertion slot 15. The limiting member includes a deformable block 35 and a limiting block 36. Two pairs of deformable blocks 35 are provided, with the two pairs of deformable blocks 35 respectively located on both sides of the connector 34. One end of the deformable block 35 is elastically connected to the connector 34, and the other end extends away from the male connector 32 and is a free end. The limiting block 36 is located on the side of the deformable block 35 facing the slot wall of the insertion slot 15. The end of the limiting block 36 near the bottom of the insertion slot 15 is provided with an inclined guide surface 361; that is, when the connector 34 is... During the process of inserting the connector 34 into the insertion slot 15, the deformation block 35 can be deformed by the guiding action of the inclined guide surface 361, so that the connector 34 can smoothly enter the insertion slot 15. The carrier 1 has a limiting hole 16 on the groove wall of the insertion slot 15. The limiting hole 16 is connected to the outside of the carrier 1. The limiting block 36 is engaged in the limiting hole 16. So when the connector 34 is inserted into the insertion slot 15 to the position of the limiting hole 16, the deformation block 35 is reset, so that the limiting block 36 is engaged in the limiting hole 16, thereby completing the installation of the male connector 32 and the carrier 1.

[0039] Reference Figure 1 and Figure 2 In order to successfully complete the injection molding of the carrier 1, a branch pipe 17 is integrally formed near the water inlet pipe 12 of the carrier 1. The two ends of the branch pipe 17 are connected to the water inlet channel 13 and the outside of the carrier 1, respectively. A plug ball 18 is plugged inside the branch pipe 17 to prevent the cleaning fluid from flowing out of the branch pipe 17.

[0040] The implementation principle of Example 1 is as follows: When assembling the nozzle, first assemble the nozzle ball 2 at the outlet 11, then install the plug ball 18 at the branch pipe 17, then insert the thermistor 31 into the receiving groove 14 from the insertion groove 15, then pour thermally conductive adhesive into the insertion groove 15 until it is close to the insertion groove 15, and finally insert the plug 34 of the male connector 32 into the insertion groove 15, thus completing the assembly of the entire nozzle and forming an integrated heating nozzle. In actual use, the water supply pipe 4 is inserted into the water inlet pipe 12 and connected to the female terminal of the car's power system through the male connector 32. When the windshield washer function is needed, the cleaning fluid enters from the water supply pipe 4, and at the same time, the thermistor 31 is powered on and begins to work. Heat is quickly transferred to the carrier 1 through the thermally conductive adhesive layer 33, and the carrier 1 then evenly transfers the heat to the cleaning fluid flowing through the heating area, which is then sprayed out by the nozzle ball 2 to clean the windshield.

[0041] Example 2

[0042] Reference Figure 5 and Figure 6The difference between this embodiment and embodiment 1 is that the car hood heating nozzle also includes a wire 5. One end of the wire 5 is electrically connected to the lead of the thermistor 31, and the other end is electrically connected to the terminal of the male connector 32. Thus, depending on the actual use scenario, the male connector 32 can be directly led out through the wire 5 and the installation position of the male connector 32 can be arranged in a more suitable position. A positioning groove 19 is provided in the receiving groove 14 near the water outlet 11, and the thermistor 31 is snapped into the positioning groove 19.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
