[0029] Reference Figures 1 to 4A switching valve includes: a housing 110, a hollow water guide cavity 150 is formed inside, a water inlet channel 100 is extended from one end of the housing 110, and the water inlet channel 100 is conductively connected with the water guide cavity 150, and a first water outlet channel 120 and a second water outlet channel 130 are extended from the other end of the housing 110, the first water outlet channel 120 is provided with a first through hole 190, and the first water outlet channel 120 is conductively connected with the water guide cavity 150 through the first through hole 190, and the second water outlet channel 130 is provided with a second through hole 160, and the second water outlet channel 130 is conductively connected with the water guide cavity 150 through the second through hole 160;
[0030] The switching assembly 140 is disposed in the water guiding cavity 150 , and the switching assembly 140 can movably cover the first through hole 190 or the second through hole 160 ;
[0031] Among them, when the water inlet channel 100 is connected to an external water source, when the switching component 140 covers the first through hole 190, the first water outlet channel 120 stops discharging water, and the second water outlet channel 130 discharges water; when the switching component 140 covers the second through hole 160, the second water outlet channel 130 stops discharging water, and the first water outlet channel 120 discharges water; when the switching component 140 neither covers the first through hole 190 nor the second through hole 160, the first water outlet channel 120 and the second water outlet channel 130 discharge water at the same time. According to some embodiments of the utility model, the first water outlet channel 120 and the second water outlet channel 130 are independent pipes, and the first water outlet channel 120 and the second water outlet channel 130 are arranged side by side. The first water outlet channel 120 and the second water outlet channel 130 arranged side by side can reduce the attenuation of water pressure, ensuring that the first water outlet channel 120 and the second water outlet channel 130 have sufficient water pressure.
[0032] The hollow water guiding cavity 150 formed in the shell 110 and the water inlet channel 100 and double water outlet channel design at both ends thereof realize the water flow guiding function of a single inlet and double outlets, and improve the compactness of the structure of the shell 110; the switching component 140 can be movably covered on the first through hole 190 or the second through hole 160 as needed to realize the start and stop control of a single water outlet channel, so that the water flow can be quickly and accurately switched between the first water outlet channel 120 and the second water outlet channel 130, thereby improving the flexibility of the equipment; using the switching component 140 for switching can reduce the difficulty of operation and facilitate switching; the switching valve can meet the water flow switching needs in different situations while improving the reliability and water-saving efficiency of the equipment, which is conducive to reducing maintenance costs.
[0033] The switching assembly 140 includes a switching handle 200, an elastic member and a sealing plug 220. The switching handle 200 is fixedly connected to the sealing plug 220. The elastic member is arranged between the switching handle 200 and the sealing plug 220. The size and shape of the sealing plug 220 and the first through hole 190 and the second through hole 160 are mutually adapted. Through the switching handle 200, the opening and closing of the first through hole 190 and the second through hole 160 can be quickly switched, which greatly improves the convenience of using the valve. It is understandable that in an alternative solution, the function of the sealing plug 220 can be realized by a ball screw, but in this embodiment, a sealing plug 220 made of rubber is preferred. The main consideration for using the rubber sealing plug 220 is that it can effectively reduce the overall thickness of the switching assembly 140, which not only allows the housing 110 to pursue a lighter and thinner shape in design, but also improves the overall aesthetics of the valve. The sealing plug 220 made of rubber material not only meets the basic sealing performance requirements, but also takes into account the space utilization and appearance aesthetic requirements, showing superior comprehensive performance advantages.
[0034] The elastic member is a spring 210, one end of which abuts against the conversion handle 200, and the other end abuts against the sealing plug 220. The spring 210 can press the sealing plug 220 between the first through hole 190 and the second through hole 160 to prevent the valve from opening due to water pressure changes.
[0035] The housing 110 is provided with a third through hole, and the third through hole is provided corresponding to the switching handle 200, and the switching handle 200 is provided to extend outward from the third through hole. The operator can directly rotate the operating handle from the outside without disassembling the housing 110, which further improves the convenience of using the switching valve and makes the structure of the switching valve more compact.
[0036] A sealing gasket is provided between the third through hole and the conversion handle 200, one end of the sealing gasket abuts against the housing, and the other end abuts against the conversion handle 200. The gap between the third through hole and the conversion handle 200 can be effectively filled, the sealing performance inside and outside the valve body is improved, and it is ensured that during the operation of the valve body, no liquid or gas will leak through the third through hole, thereby ensuring the normal function of the switching valve and the safe operation of the system.
[0037] The housing 110 is provided with a limiting portion 180, and the bottom of the conversion handle 200 is rotatably mounted on the limiting portion 180, and the limiting portion 180 limits the rotation angle of the conversion handle 200 between the first through hole 190 and the second through hole 160. It is ensured that after the conversion handle 200 abuts against the limiting portion 180, it can accurately cover the first through hole 190 or the second through hole 160. The limiting portion 180 ensures that when the conversion handle 200 rotates between the first through hole 190 and the second through hole 160, it can be accurately positioned at a preset angle, thereby accurately controlling the sealing plug 220 to cover the through hole to be switched, avoiding the problem of poor sealing or misoperation caused by excessive rotation of the conversion handle 200.
[0038] The first through hole 190 and the second through hole 160 are respectively provided with support ribs 170. Under high temperature conditions, the sealing material may become soft or even melt. The presence of the support ribs 170 can fix and support the sealing member to prevent it from displacement due to thermal expansion and contraction or water flow erosion, thereby ensuring that the valve always maintains good sealing performance under various temperature and pressure conditions.
[0039] The first through hole 190 and the second through hole 160 have the same diameter, and the length of the support rib 170 is greater than the diameter of the first through hole 190 and the second through hole 160. Ensure that the support rib 170 has sufficient length to support the seal.
[0040] The supporting rib 170 is in an arc shape, so as to better utilize the space between the first through hole 190 and the second through hole 160 and also increase the mechanical strength of the first through hole 190 and the second through hole 160 .
[0041] The diameter of the water inlet channel 100 is larger than the diameters of the first water outlet channel 120 and the second water outlet channel 130. Setting a relatively large diameter of the water inlet channel 100 can ensure that there is sufficient water pressure in the water guide cavity 150.
[0042] In this embodiment, the switching valve mainly includes a housing 110 and a switching assembly 140. A hollow water guide cavity 150 is formed inside the housing 110, and a water inlet channel 100 connected to the water guide cavity 150 extends from one end of the housing 110, and the diameter of the water inlet channel 100 is designed to be larger than the diameters of the first water outlet channel 120 and the second water outlet channel 130, so as to reduce water flow resistance and ensure sufficient water intake.
[0043] Two independent water outlet channels, namely, a first water outlet channel 120 and a second water outlet channel 130, are arranged side by side at the other end of the housing 110. Each water outlet channel has a first through hole 190 and a second through hole 160 respectively connected to the water guide cavity 150. The two through holes are both provided with arc-shaped supporting ribs 170, the length of which is greater than the diameter of the through hole, in order to enhance the structural stability and prevent the seal from deforming at high temperature.
[0044] The switching assembly 140 is placed in the water guiding cavity 150, and mainly includes a switching handle 200, an elastic member (here, a spring 210) and a sealing plug 220. The switching handle 200 is installed in a pre-set limiter 180 of the housing 110 through a rotating shaft at the bottom. The limiter 180 limits the switching handle 200 to rotate only between the first through hole 190 and the second through hole 160, ensuring that each rotation can accurately cover the sealing plug 220 on the target through hole.
[0045] A third through hole is also provided on the housing 110, and the conversion handle 200 extends outward from the through hole. A sealing gasket is installed between the third through hole and the conversion handle 200, which ensures the sealing performance of the entire valve and also facilitates the user's operation of the handle.
[0046] In actual applications, when the water inlet channel 100 is connected to the water source, by turning the conversion handle 200, water can be selectively allowed to flow through the first water outlet channel 120 or the second water outlet channel 130, or the position of the conversion handle 200 can be adjusted to allow water to flow out of the two water outlet channels at the same time, thereby achieving flexible and efficient water flow switching control.
[0047] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
