Technical Field
[0001] This utility model relates to the field of electronic water pump technology, specifically to an electronic water pump designed to prevent dry running. Background Technology
[0002] An electronic water pump is a device that uses electricity to transport liquids. It can be effectively used in automotive, medical, and industrial fields. It consists of a motor, impeller, and pump body to form a water pump, which effectively transports liquids. Its electronic control unit controls the operation of the water pump. However, during use, it is inconvenient to effectively monitor the operation of the water pump, which can easily lead to the electronic water pump running dry and damage the motor and impeller.
[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application CN201811440469.1, filed on 2018-11-29) provides an anti-dry-running electronic water pump. This pump uses the cooperation of a buffer column, buffer hole, fixed column, moving block, slide groove, limiting groove, limiting block, first spring, second spring, and mounting plate to achieve vibration damping of the pump body. Through the cooperation of a detector, connecting pipe, electrode, fixing plate, sealing ring, and first bolt, the two electrodes are connected when there is water inside the connecting pipe and disconnected when there is no water inside the connecting pipe, thus achieving the purpose of detecting whether the pump body is running dry. While the prior art can achieve anti-dry-running, it is inconvenient to effectively control the sealing stability of the electrode assembly during operation, and its installation position is prone to water leakage, making detection difficult.
[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing electronic water pumps. Utility Model Content

[0009] Preferably, the limiting engagement mechanism includes a lead screw rotatably mounted on the inner surface of the positioning seat, a belt rotatably mounted on the right side of the outer surface of the lead screw, a locking member threadedly connected to the outer surface of the lead screw, which limits and slides the locking member inside the positioning seat, and a protective cover engaged with the outer surface of the locking member, while a spur gear is mounted on the outer surface of the lead screw; a limiting member is slidably connected to the inner surface of the positioning seat, and a limiting assembly is slidably connected to the outer surface of the limiting member, and a return spring is elastically connected between the limiting assembly and the limiting member, while a spur gear is engaged with the lower surface of the limiting member.
[0010] The above structure facilitates stable assembly of the protective cover during use and prevents it from falling off.
[0011] Preferably, the positioning seat forms a threaded adjustment limiting sliding structure through the lead screw and the clamp, and the clamp and the protective cover form a limiting engagement structure, and the lead screw and the spur gear form an integrated structure.
[0012] The above structure allows for effective control of the adjustment of the clips during use, thereby controlling the stability of the protective cover assembly.
[0013] Preferably, the positioning seat and the limiting component form an integrated structure, and the limiting component forms an elastic sliding structure with the limiting member through a reset spring, and the limiting member forms a limiting engagement structure with the lead screw through a spur gear.

During electrode detector assembly, it will work with the nested sealing ring to improve the sealing performance of the electrode detector assembly. Through the use of the installed positioning block and protrusion, it forms a corresponding locking connection with the positioning plate on the fixed seat, improving the stability of the electrode detector connection. Furthermore, the compression spring between the positioning plate and the fixed seat can effectively control the position of the positioning plate and form a limiting locking engagement with the positioning block. In conjunction with the limiting plate, it can prevent the positioning plate from disengaging and causing excessive movement, thus avoiding the inability to assemble when replacing the electrode detector.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-6 The present invention provides the following technical solution: an electronic water pump that prevents dry running, wherein an electronic water pump body 1 is provided for easy positioning and assembly.
[0032] Example 1: As Figures 1-4The technical solution shown is provided by this utility model as follows: An anti-dry-running electronic water pump, comprising: a positioning seat 2, installed on the outer surface of the electronic water pump body 1, with a sealing ring 3 attached to the outer surface of the positioning seat 2, and a protective cover 4 attached to the outer surface of the sealing ring 3; the positioning seat 2 is provided with a limiting engagement mechanism; the positioning seat 2 and the electronic water pump body 1 form an integrated structure, and the positioning seat 2 and the protective cover 4 form a sealing structure through the sealing ring 3; the limiting engagement mechanism... The positioning seat 2 has a lead screw 5 rotating on its inner surface, and a belt 6 rotating on the right side of the outer surface of the lead screw 5. A locking piece 7 is threadedly connected to the outer surface of the lead screw 5, limiting and sliding the locking piece 7 inside the positioning seat 2. A protective cover 4 is engaged with the outer surface of the locking piece 7. A spur gear 8 is installed on the outer surface of the lead screw 5. The positioning seat 2 forms a threaded adjustment limiting sliding structure through the lead screw 5 and the locking piece 7. The locking piece 7 and the protective cover 4 form a limiting engagement structure. The lead screw 5 and the spur gear 8 form an integrated structure.
[0033] In use, a positioning seat 2 is installed on the outer surface of the electronic water pump body 1, and a protective cover 4 is assembled with a sealing ring 3 in conjunction with the positioning seat 2. When the protective cover 4 aligns with the positioning seat 2, a through-hole clamp 7 is inserted, and a control limiter 9 disengages from the spur gear 8. This allows the control screw 5 to rotate, thereby coordinating with the adjustment of the belt 6 to achieve synchronous control of the stability of the rotation on both sides of the positioning seat 2, and to control the position of the screw 5 threaded control clamp 7. The control clamp 7 then engages with the protective cover 4 for subsequent sealing and protection.
[0034] Example 2: Figure 1 and Figure 5 The technical solution shown, based on Embodiment 1, further discloses the limiting operation of the lead screw 5, the specific details of which are as follows: the inner surface of the positioning seat 2 is slidably connected to the limiting member 9, and the outer surface of the limiting member 9 is slidably connected to the limiting assembly 11, and a return spring 10 is elastically connected between the limiting assembly 11 and the limiting member 9, while a spur gear 8 is engaged with the lower surface of the limiting member 9; the positioning seat 2 and the limiting assembly 11 form an integrated structure, and the limiting assembly 11 and the limiting member 9 form an elastic sliding structure through the return spring 10, and the limiting member 9 and the lead screw 5 form a limiting engagement structure through the spur gear 8.
[0035] When the limiting member 9 moves upward, it compresses and contracts the return spring 10 into the limiting assembly 11, thereby controlling the limiting member 9 to disengage from the limiting engagement of the spur gear 8. This allows the spur gear 8 to rotate. Once the spur gear 8 has completed its rotation, it will disengage from the limiting member 9. The position of the limiting member 9 can be controlled elastically, and the spur gear 8 can be engaged. This prevents disengagement after the protective cover 4 is assembled.
[0036] Example 3: Figure 1 , Figure 2 and Figure 6 The technical solution shown, based on Embodiment 2, further discloses the assembly of the electrode detector 12, the specific details of which are as follows: The electrode detector 12 is nested and connected to the inner surface of the positioning base 2, and a sealing ring 13 is nested on the outer surface of the electrode detector 12. A positioning block 14 is installed on the outer surface of the electrode detector 12, and a protrusion 15 is installed on the outer surface of the positioning block 14. The positioning block 14 is thus provided with a positioning connection mechanism; the electrode detector 12 and the positioning base 2 form a sealed through-structure through the sealing ring 13, and the electrode detector 12 is embedded in the outer surface of the positioning block 14, and the positioning... Block 14 and protrusion 15 form an integrated structure; the positioning connection mechanism includes a positioning plate 16 connected to the outer surface of the positioning block 14, and a fixed seat 19 is slidably connected through the outer surface of the positioning plate 16, and a compression spring 18 is elastically connected between the fixed seat 19 and the positioning plate 16, while a limiting plate 17 is installed at the end of the positioning plate 16; the positioning block 14 and the positioning plate 16 form a limiting engagement structure through the protrusion 15, and the positioning plate 16 forms an elastic limiting sliding with the fixed seat 19 through the limiting plate 17 and the compression spring 18, while the fixed seat 19 is set at an angle to the central axis of the inner surface of the electrode detector 12.
[0037] Before assembling the protective cover 4, the electrode detector 12 is assembled, passing through the positioning seat 2 and penetrating into the electronic water pump body 1. The sealing ring 13 assembled by the electrode detector 12 improves the sealing stability. Rotating the electrode detector 12 drives the positioning block 14, which compresses and adjusts the positioning plate 16 on the fixed seat 19. This controls the positioning plate 16 to slide within the fixed seat 19 and compresses and contracts the compression spring 18, moving the positioning block 14 to the underside of the positioning plate 16. The protrusion 15 installed on the positioning block 14 is engaged in the positioning block 14, effectively forming a limiting engagement and limiting engagement of the electrode detector 12. When disassembling the electrode detector 12 later, the positioning plate 16 will elastically reset and cooperate with the limiting plate 17 to prevent excessive movement. In later use, the leak detector 20, which is nested and assembled with the protective cover 4, is used for leak detection, improving the safety of the electrode detector 12.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
