Description

Technical Field

[0001] This utility model belongs to the field of water circuit accessories for water-heated blankets, specifically relating to a water distributor and a water-heated blanket having the water distributor. Background Technology

[0002] Water-heated blankets are a new type of electric blanket that uses water as the heat transfer medium. They heat water through an independent main unit and circulate it within the blanket body to provide warmth. The core technology includes a water-electricity separation design, with no heating elements in the blanket body, thus fundamentally eliminating electromagnetic radiation. Water-heated blankets have become the mainstream product replacing traditional electric heating wire blankets. Among them, Chinese utility model patent number 202120688463.7 discloses a water-heated blanket water distribution component, which includes a shell and a water distributor inside. The shell consists of an upper shell and a lower shell, with a hole for a water supply pipe to pass through. The water distributor has multiple water outlets. The water distributor is fixed to the shell, and the end of each water outlet is a tapered interface with a larger inner diameter and a smaller outer diameter. An annular groove is coaxially provided on the inner side of the tapered interface, and upper and lower toothed clamping plates are respectively provided on the upper and lower sides of the annular groove to cooperate with it. The problem is that the manifold of this type of water-heated blanket does not have the function of regulating water flow. That is, the water flow of the supply and return water circuits of the manifold cannot be adjusted through the manifold, which makes it inconvenient to adjust the temperature of the blanket body. This has certain limitations and therefore requires further improvement. Utility Model Content

[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] like Figure 1-6 As shown, this water distributor, mainly used in water-heated blanket products, includes a main housing 1 and a water distribution component 2 installed on the main housing 1. The water distribution component 2 includes a water supply path 3 and a water return path 4. The water supply path 3 has an inlet 31 and several outlets 32, all connected to the inlet 31. The outlets 32 of the water supply path 3 are used to connect to the inlet end of the water pipe inside the water-heated blanket body. The inlet 31 of the water supply path 3 is used to connect to the output end of the main water circuit assembly of the water-heated blanket. (This is based on the technology in this field.) As will be understood by all personnel, the return water circuit 4 is provided with an outlet 41 and several return water inlets 42, each connected to the outlet 41. The return water inlets 42 of the return water circuit 4 are used to connect to the outlet end of the water pipe inside the water-heated blanket body, and the outlet 41 of the return water circuit 4 is used to connect to the input end of the main water circuit component of the water-heated blanket. As will be understood by those skilled in the art, the supply water circuit 3 and / or the return water circuit 4 are provided with switch valves 5 for closing part of the water circuit. The switch valve 5 on the supply water circuit 3 is used to open or close... The output port 32 of the closed section is used to regulate the output flow of the water supply circuit 3. When the switch valve 5 on the water supply circuit 3 is operated to close the output port 32, the output flow of the water supply circuit 3 decreases. When the switch valve 5 is switched from the closed state to the open state, the output flow of the water supply circuit 3 increases. This can be used to regulate the temperature of the water-heated blanket. The switch valve 5 on the return water circuit 4 is used to open or close the return water port 42 to regulate the return water flow of the return water circuit 4. When the switch valve 5 on the return water circuit 4 is operated to close the return water port 42, the return water flow of the return water circuit 4 decreases. When the switch valve 5 is switched from the closed state to the open state, the return water flow of the return water circuit 4 increases. This can be used to regulate the temperature of the water-heated blanket. In this embodiment, both the water supply circuit 3 and the return water circuit 4 are equipped with switch valves 5. The switch valves 5 on the water supply circuit 3 and the return water circuit 4 can be adjusted independently, making the adjustment methods diversified and forming different water flow level adjustment options.

[0024] The water distribution component 2 is provided with a valve seat 6, and the valve seat 6 is provided with a valve cavity 61 that communicates with the water passage of the water distribution component 2. The switch valve 5 is provided on the valve cavity 61, and a sealing ring 7 is provided between the switch valve 5 and the inner wall of the valve cavity 61. The sealing ring 7 is provided to prevent water leakage. The switch valve 5 is at least partially located outside the valve cavity 61 and exposed on the main housing 1 to form the operating part of the switch valve 5, so that the consumer can open and close the switch valve 5 by operating the switch valve 5. The valve seat 6, switch valve 5 and sealing ring 7 of the water distribution component 2 have a simple structure and are easy to manufacture.

[0025] In some embodiments of this utility model, such as Figure 3 As shown, the water distribution component 2 includes a water supply bracket 21 and a water return bracket 22.

The switch valves 5 on the water supply circuit 3 and / or the return water circuit 4 are located between the two sets of branch pipes 24 at the front and the two sets of branch pipes 24 at the rear of the corresponding bracket. In this embodiment, the switch valves 5 on the water supply circuit 3 and the return water circuit 4 are located between the two sets of branch pipes 24 at the front and the two sets of branch pipes 24 at the rear of the corresponding bracket. That is, when the switch valve 5 is switched to the closed state, it can shut off the water flow of the two sets of branch pipes 24 at the rear of the corresponding bracket.

[0026] In some embodiments of this utility model, such as Figure 3 As shown, the front end of the main pipe 23 of the water supply bracket 21 forms the inlet 31 of the water supply path 3, the branch pipe 24 of the water supply bracket 21 forms the outlet 32 ​​of the water supply path 3, the front end of the main pipe 23 of the return water bracket 22 forms the outlet 41 of the return water path 4, and the branch pipe 24 of the return water bracket 22 forms the return outlet 42 of the return water path 4. like Figure 1 As shown, the main housing 1 is provided with an opening 11 for the front end of the main pipe 23 to extend out. The opening 11 is also used to position the main pipe 23. The rear and side parts of the main housing 1 are provided with openings 12 corresponding to the branch pipes 24. The openings 12 are used for external water pipes to enter and connect with the branch pipes 24.

[0027] In some embodiments of this utility model, such as Figure 3 As shown, the water supply bracket 21 and the return water bracket 22 are arranged at left and right intervals. The water supply bracket 21 and the return water bracket 22 are connected by a connecting frame 25 located between them. The connecting frame 25 is provided with a positioning groove 251. The main housing 1 is provided with a positioning post 13 extending into the positioning groove 251. The cooperation between the positioning post 13 and the positioning groove 251 is used for positioning between the water distribution component 2 and the main housing 1.

[0028] In some embodiments of this utility model, such as Figure 3 , 4 As shown in Figure 6, the switching valve 5 includes a valve core 51 and a knob 52 fixed to the valve core 51. The knob 52 constitutes the operating part of the switching valve 5. The knob 52 is designed to facilitate operation by the consumer. The sealing ring 7 is located between the side of the valve core 51 and the inner wall of the valve cavity 61. The side of the valve core 51 is provided with an annular groove for positioning the sealing ring. There are two sets of sealing rings 7, which are arranged at intervals along the axial direction of the valve core 51. The arrangement of the two sets of sealing rings 7 helps to ensure the reliability of the seal. The switching valve 5 is rotatably mounted on the valve seat 6.

[0029] In some embodiments of this utility model, such as Figure 3 , 4 As shown in Figure 6, the valve core 51 has a water passage chamber 511 inside, and the valve core 51 has an inlet 512 and an outlet 513 that are respectively connected to the water passage chamber 511. By rotating the switch valve 5, the inlet 512 and the outlet 513 can be blocked or opened. The inlet 512 and the outlet 513 are arranged opposite to each other.

[0030] In some embodiments of this utility model, the knob 52 includes a first limiting platform 521, a second limiting platform 522, and a holding block 523 connected axially in sequence. The diameter of the first limiting platform 521 is larger than the diameter of the second limiting platform 522. The main housing 1 is provided with a through hole 14 corresponding to the knob 52 and a stepped groove 15 connected to the inner end of the through hole 14 and having a diameter larger than the through hole 14. The first limiting platform 521 is located between the stepped groove 15 and the valve seat 6, thereby limiting the knob 52. At the same time, it limits the switch valve 5 to the valve seat 6 between the main housing 1 and the water distribution component 2. Through the auxiliary positioning effect of the stepped groove 15 of the main housing 1, the switch valve 5 is prevented from detaching from the valve seat 6. The second limiting platform 522 passes through the through hole 14, and the holding block 523 is located at the outer end of the through hole 14. The consumer operates the knob 52 by grasping the holding block 523.

[0031] In some embodiments of this utility model, such as Figure 5 , 6 As shown, the knob 52 includes a first limiting block 524, which extends circumferentially and is arc-shaped. The main housing 1 has a second limiting block 16 that cooperates with the first limiting block 524. The second limiting block 16 is located on the stepped groove 15. When the knob 52 rotates, it stops when the first limiting block 524 comes into contact with the second limiting block 16. The first limiting block 524 is connected to the side of the first limiting platform 521. The cooperation between the first limiting block 524 and the second limiting block 16 prevents the knob 52 from rotating in one direction for more than two turns continuously.

[0032] A positioning protrusion ring 17 is provided on the inner wall of the main housing 1 corresponding to the bottom of the valve seat 6. The bottom of the valve seat 6 is set inside the positioning protrusion ring 17, thereby improving the installation stability of the water distribution component 2.
