Description

Technical Field

[0001] This utility model relates to the structure of electric water heater connectors and belongs to the technical field of electric water heater connector structures. Background Technology

[0002] Electric water heaters are water heaters that use electricity as an energy source for heating. They are one of the three major types of water heaters, along with gas water heaters and solar water heaters. Electric water heaters can be divided into three types according to their heating power: storage type (also known as tank type or thermal storage type), instant type, and quick-heating type (also known as semi-storage type). Currently, household electric water heaters on the market have tightly connected joints. For example, patent number CN201820641645.7 discloses a household electric water heater with a leak-proof joint. This leak-proof joint household electric water heater can effectively prevent water leakage at the pipe joint, has a longer service life, and has a reliable connection to prevent breakage.

[0003] The aforementioned connector requires tools to effectively and tightly connect to the pipe interface of the electric water heater, which is inconvenient to use. Therefore, we have designed a new connector structure for electric water heaters. Utility Model Content

[0004] The purpose of this utility model is to provide a connector structure for electric water heaters to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric water heater connector structure, including a connector seat and a threaded connection channel. The threaded connection channel is fixedly disposed inside the connector seat. Conical sealing ring seats are installed at the top and bottom of the connector seat. A strip connecting plate is installed on the side of the connector seat. A strip groove is opened at the top of the strip connecting plate. A handle strip is installed inside the strip groove. A strip connector head is provided at the bottom of the handle strip. A pad is installed on the outer surface of the strip connector head. A connection hole is opened on the side of the strip connecting plate. The handle strip is fastened inside the connection hole through the strip connector head and the pad.

[0006] In the above-mentioned electric water heater connector structure, the top conical sealing ring seat is equipped with an upper sealing connecting sleeve, and the bottom conical sealing ring seat is equipped with a lower sealing connecting sleeve.

[0007] In the above-mentioned electric water heater connector structure, an inflatable sealing ring is installed at the bottom of the lower sealing connecting sleeve, a sealing ring edge is provided at the inner ring of the inflatable sealing ring, and an air inlet is installed at the air inlet of the inflatable sealing ring.

[0008] In the above-mentioned electric water heater connector structure, the air inlet passage passes through the channel of the lower sealing connecting sleeve and is provided with a horn-shaped air inlet cover, and a clamping block that contacts the lower sealing connecting sleeve is provided in the middle of the air inlet passage.

[0009] In the above-mentioned electric water heater connector structure, the length of the handle insert exceeds two-thirds of the height of the connector seat, and a hand grip area is provided at the upper part of the handle insert.

[0010] In the above-mentioned electric water heater connector structure, the depth of the connecting hole is greater than the thickness of the connecting plate, and the end of the connecting hole extends to the connector seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model relates to an electric water heater connector structure. A connecting plate is installed on the side of the connector seat, and a connector head is set at the bottom of the handle connector. A pad is installed on the outer surface of the connector head. The handle connector is securely fixed inside the connection hole via the connector head and the pad, connecting to the connecting plate. In use, the handle connector is held perpendicular to the connector plate, and rotation using a lever principle connects the threaded connection channel to the electric water heater. This allows for better installation of the connector seat, providing convenience and simplifying installation without the need for tools. Furthermore, an inflatable sealing ring is installed at the bottom of the lower sealing sleeve. The inner ring of the inflatable sealing ring has a sealing edge, and an air inlet is installed at the inflation hole of the inflatable sealing ring, providing a good sealing effect. This ensures good sealing when the lower sealing sleeve connects to the pipe, reducing leakage. Attached Figure Description
