Technical Field

[0001] The utility model relates to the technical field of valve bodies, in particular to a concealed cooling exhaust valve and a water outlet device. Background Art

[0002] When the user opens the valve of the existing shower products, cold water comes out first, and hot water will come out after a certain period of time. Especially in winter, the cold water will spill or splash on the user, making people very uncomfortable. However, the existing cooling products on the market have certain disadvantages. For example, when using electronic cooling, electricity is required, which increases the danger; the temperature of the temperature control valve is affected by the temperature adjustment, and the set temperature of the temperature control valve must be greater than the design temperature of the temperature sensor. In addition, when the cold water is discharged mechanically, the cold water cannot be automatically turned off; at the same time, the water in the cold water pipe is discharged together, which will waste water.

DETAILED DESCRIPTION

[0025] Combination Figures 1 to 6 As shown, this embodiment provides a water outlet device, including a cold water discharge concealed valve. The cold water discharge concealed valve includes a valve body 1 and a valve core 2 installed in the valve body 1, the valve body 1 is connected with a hot water channel 11 and a cold water channel 12, and also includes a cold water discharge channel 3 connecting the hot water channel 11 and the water outlet end of the valve core 2, the cold water discharge channel 3 is suitable for preferentially discharging the cold water in the hot water channel 11 so that the hot water can quickly reach the valve core 2 for mixing.

[0026] In this embodiment, the water outlet device may include a plurality of water outlets 8. The valve core 2 is mounted on the valve body 1 to control and adjust the opening ratio of the cold water channel 12 and the hot water channel 11 to mix the cold and hot water. The valve core 2 is fixed by a gland 4. Of course, a handle 5 is also provided on the valve core 2 to control the valve core 2 and a panel 6 is provided for decoration.

[0027] The valve body 1 is connected with a hot water channel 11 and a cold water channel 12, a cold water discharge channel 3 is provided between the hot water channel 11 and the water outlet of the valve core 2, a cold water discharge device 7 is provided in the cold water discharge channel 3, and the cold water discharge device 7 is configured to be automatically closed when the water temperature passing through the cold water discharge channel 3 is higher than a preset value. In one embodiment, the cold water discharge device 7 is provided at the rear end of the hot water channel 11, so that the cold water in the hot water channel 11 can be discharged as much as possible.

[0028] Combination Figures 3 to 6As shown, in this embodiment, the cooling device 7 includes a temperature sensing element 71, a valve stem 72, a fixed joint 73, a fixed seat 74 and a cooling pressure cover 75, wherein the valve stem 72 is mounted on the fixed seat 74 through the fixed joint 73, and a water passage 77 communicating with the cooling channel 3 is formed in the fixed seat 74, and the valve stem 72 is suitable for moving in the fixed seat 74, and when it moves to the first position, it can block the water passage 77 to close the cooling channel 3, and when it moves to the second position, the blocking of the water passage 77 is cancelled, so that the cooling channel 3 is conducted. The temperature sensing element 71 is connected to one end of the valve stem 72 to automatically extend and drive the valve stem 72 to move to the first position to close the cooling channel 3 when the temperature exceeds the preset value. In this embodiment, the cooling device 7 also includes a switch key 76, and the switch key 76 controls the valve stem 72 to move toward the temperature sensing element 71 to open the cooling channel 3. Here, the switch key 76 can be set at the end of the valve stem 72 away from the temperature sensing element 71, so that when the switch key 76 is pressed, the valve stem 72 is driven to move toward the temperature sensing element 71. It should be noted that in this embodiment, the temperature sensing element 71 is set at one end of the cold discharge channel 3 close to the hot water channel 11, so as to sense the temperature of the water entering the cold discharge channel 3 from the hot water channel 11 in real time. In addition, the switch key 76 is not limited in its operation mode. In this case, pressing is only an operation mode to realize other cold discharge functions. In other embodiments, other modes such as rotation and bouncing are not limited.

[0029] The preset value in this embodiment refers to the temperature at which the temperature sensing element can automatically extend, which can be different from the mixing temperature controlled by the valve core 2, making the automatic closing more stable. The temperature sensing element 71 is not limited to a specific material, and can be an existing material element that can achieve length expansion and contraction changes due to temperature changes.

[0030] In another embodiment, a mounting position for mounting the valve stem 72 is provided in the valve body 1 so that the valve stem 72 can be directly installed in the valve body 1. This setting is equivalent to integrating the fixing seat 74 in the valve body 1, that is, there is no need to set the fixing seat 74 separately, making the structure more compact.

[0031] In another preferred embodiment, an elastic member is provided at one end of the valve stem 72 away from the temperature sensing element 71 to buffer the valve stem when the temperature sensing element expands. The elastic member here is a safety spring, which is used to adjust the movement of the valve stem 72 or its matching part within a safe range to prevent damage to the valve stem or its matching part when the temperature sensing element 71 expands too much.

[0032] The present embodiment scheme can automatically and in real time monitor the water temperature in the hot water channel 11 by setting the temperature sensing element 71 as the control element for controlling the cold discharge channel 3, and automatically extend to close the cold discharge channel 3 after the temperature rises to the preset value. When the user uses it, the cold discharge channel 3 and the water outlet device can be controlled to open first, and the cold water in the hot water channel 11 can be discharged through the cold discharge channel 3. When the cold discharge channel 3 is automatically closed, the valve core 2 is opened to control the water outlet temperature and water outlet. Since the cold water in the hot water channel 11 has been preferentially discharged from the cold discharge channel 3 together with the cold water remaining in the water outlet device, when the valve core 2 is opened, the hot water and the cold water are mixed, that is, the hot water in the hot water channel 11 can quickly enter the valve core 2 and mix with the cold water, which greatly shortens the problem of long duration of cold water outlet caused by the cold water from the cold water channel 12 and the cold water remaining in the hot water channel 11 mixing in the valve core 2, shortens the water outlet time of the mixed cold water, and improves the user experience.

[0033] It should be understood that the above are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.

[0034] The above description of the drawings used in the implementation manner only shows certain embodiments of the utility model and should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without paying creative work.
