Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

The utility model relates to a drainage device, which comprises a control assembly 100, a movable assembly 200, a water passing assembly 300 and a temperature sensing element 400.

In this embodiment, as shown in fig. 1,2 and 3, the control assembly 100, the movable assembly 200 and the water passing assembly 300 are distributed in the illustrated direction from top to bottom. The movable assembly 200 is provided with a water passing cavity 201, and the opening of the movable assembly 200 faces downwards to the water passing assembly 300. The control assembly 100 is capable of driving the movable assembly 200 from a first position to a second position, the first position and the second position being laterally distributed in the drawing. The control assembly 100 does not drive the movable assembly 200 to reset from the second position to the first position when reset. The water passing assembly 300 and the movable assembly 200 are slidably connected to each other. The sliding connection in the present application may be performed by sliding after the surfaces of the two features are abutted against each other, or may be performed by sliding connection by other mechanical means such as grooves. The water passing assembly 300 includes a first channel 310 and a second channel 320. The temperature sensing element 400 is installed between the water passing chamber 201 and the water passing assembly 300. Wherein, when the movable assembly 200 is in the first position and the second position, the first channel 310 and the second channel 320 have different working states. As shown in fig. 3, the movable assembly 200 is normally located at the first position, and the first channel 310 and the second channel 320 are not connected to each other and are in a disconnected state. As shown in fig. 4, when the control assembly 100 drives the movable assembly 200 to the second position, the water passing chamber 201 moves along with the movable assembly 200, and the first channel 310 and the second channel 320 are both communicated with the water passing chamber 201, so that the first channel 310 and the second channel 320 are mutually communicated. After the first channel 310 and the second channel 320 are communicated, the temperature sensing element 400 is located on a path where the first channel 310 and the second channel 320 are communicated. A fluid (e.g., water) is communicated between the first channel 310 and the second channel 320. The temperature sensing element 400 has a preset temperature, and when the temperature sensing element 400 is gradually increased from a low temperature to the preset temperature under the influence of an external temperature such as a water temperature, the temperature sensing element 400 acts to drive the movable assembly 200 to move relative to the water passing assembly 300, so that the movable assembly 200 is reset from the second position to the first position, and the first channel 310 and the second channel 320 are switched from the connected state to the disconnected state. The water draining device is automatically reset according to the liquid temperature, so that the requirements of water heater and other equipment for draining cold water at the rear of the front section can be met. After the movable assembly 200 is reset to the first position, the cold discharging function can not be automatically started due to the fact that the water temperature is reduced, and water resource waste is effectively avoided. The whole structure is simple, the use is convenient, and the later maintenance is convenient. The drainage device can be used as a standard module to be matched with various types of key shower faucets, and has wide application range. The shower faucet matched with the water discharging device can independently discharge cold water in the hot water pipeline, does not need to discharge the cold water in the cold water pipeline, and can save water more than other pre-discharging cold water faucets.

In the second aspect of the present utility model, as shown in fig. 12, the drain 001 is applied to a water supply apparatus having a hot water waterway 900. The hot water waterway 900 is connected to the first passage 310. The water supply device may be a water heater or the like. In use, the hot water in the hot water waterway 900 is mixed with external cold water for use. After the hot water waterway 900 in the water supply apparatus is used once, a part of water remains in the hot water waterway 900, and the part of water is gradually cooled in the hot water waterway 900 to become cold water before the next use. The water draining device can be used for draining the cold water remained in the hot water waterway 900 before the water supply device is started for taking the hot water next time. Specifically, the movable assembly 200 is driven to move from the first position to the second position by manually operating the control assembly 100. The water in the hot water line is discharged along the first passage 310, the water passing chamber 201, and the second passage 320. Until the hot water on the hot water pipeline is continuously connected after the cold water is discharged, when the hot water flows through the temperature sensing element 400, the temperature of the hot water can reach the preset temperature of the temperature sensing element 400, the temperature sensing element 400 drives the movable assembly 200 to reset to the first position, the first channel 310 and the second channel 320 are disconnected, and the hot water pipeline can not continuously drain through the drainage device. And then the water supply equipment supplies water through a passage of the water supply equipment. After the temperature sensing element 400 is reset, the movable assembly 200 is not automatically moved to the second position due to the decrease of the water temperature. Through drainage device, can carry out the independent emission with the residual cold water of anterior segment in the hot-water line, solve equipment such as traditional water heater and the mixed emission of anterior segment residual cold water and normal cold water pipeline and increase the extravagant problem of water resource when using hot water, effective water economy.

In some embodiments, as shown in fig. 3, the operational action of the control assembly 100 is a push-type reciprocating translation, with the push action of the control assembly 100 being in a first direction. The movement of the movable assembly 200 translates in the second direction. The first direction and the second direction intersect. Preferably, in the illustrated direction, the first direction is an up-down vertical direction, the second direction is a left-right transverse direction, and the first direction and the second direction are perpendicular to each other.

In some embodiments, as shown in fig. 1, 3, and 6, the control assembly 100 includes a push button 110 and a lever 120. The pressing member 110 may be, but not limited to, in a rod structure. The rod body is vertically installed. The shift lever 120 may be, but is not limited to, a lever structure having a bend. One end of the lever 120 serves as a hinge end 121 hinged to the pressing member 110 through a rotation shaft. In this embodiment, the lever 120 swings left and right with respect to the pressing member 110 about the rotation axis. The other end of the lever 120 is a free end 122. The free end 122 is slid onto the movable assembly 200. The pressing member 110 moves in the first direction, and there are a third position and a fourth position at the position where the pressing member 110 moves. The pressing member 110 is pressed downwards from the third position to the fourth position, and during the pressing process, the shift lever 120 swings rightwards relative to the pressing member 110, and the free end 122 of the shift lever abuts against the movable assembly 200 to slide. When the shift lever 120 swings rightward, the free end 122 abuts against the right side wall of the movable assembly 200, so that the movable assembly 200 is pushed to translate rightward, and the movable assembly 200 translates from the first position to the second position. The linear movement of the pressing piece 110 in the first direction is converted into the linear movement of the movable assembly 200 in the second direction by the swinging motion of the lever 120.

Further, as shown in fig. 1, 3 and 7, the movable assembly 200 is provided with a chute 210. The chute 210 extends left and right in the second direction. The chute 210 has a first end 211 and a second end 212 in the second direction, the first end 211 and the second end 212 being distributed right and left. The free end 122 is in abutment with the bottom surface of the chute 210 for relative sliding movement between the first end 211 and the second end 212. When the pressing member 110 is pressed down, the free end 122 slides on the bottom surface of the chute 210 until the free end 122 abuts against the second end 212, and the movable assembly 200 is pushed to translate rightward to the second position by the second end 212. When the pressing member 110 is reset from the fourth position to the third position, the free end 122 slides in the sliding slot 210, and the free end 122 does not have a pushing force in the second direction on the sliding slot 210, so that the movable assembly 200 is kept in the second position.

Wherein, as shown in fig. 1 and 3, the control assembly 100 includes a first elastic member 130. The first elastic member 130 may be a first spring. After the control assembly 100 moves to drive the movable assembly 200 to move to the second position, the first elastic member 130 has a first elastic force on the control assembly 100, and the first elastic force can drive the control assembly 100 to reset, so that the movable assembly 200 can be kept at the second position. As shown in fig. 3, in the present embodiment, one end of the first elastic member 130 abuts against the pressing member 110, and the other end abuts against a fixed member in the drainage device. As shown in fig. 4, when the pressing member 110 is pressed down, the first elastic member 130 is elastically compressed. As shown in fig. 5, after the movable assembly 200 reaches the second position, the pressing piece 110 is released. The pressing member 110 automatically resets upward under the first elastic force of the first elastic member 130. After the user presses the control assembly 100, the first elastic member 130 is utilized to automatically reset the control assembly 100, and the temperature sensing element 400 is matched to realize the integral automatic reset action of the drainage device.

In some embodiments, as shown in fig. 1, 3, 7, and 8, the movable assembly 200 includes an adapter 220 and a movable mount 230. The adaptor 220 is fixedly mounted on the movable base 230, and the adaptor 220 and the movable base 230 move synchronously. The water passing cavity 201 is formed on the end surface of the movable seat 230 facing the water passing component 300. In this embodiment, the water passing component 300 is located below the movable seat 230, and the water passing cavity 201 is formed on the bottom surface of the movable seat 230. The sliding groove 210 is formed on the adaptor 220, and one end (the free end 122) of the control assembly 100 slides in the sliding groove 210 on the adaptor 220. According to different models, the adaptor base 220 and the movable base 230 with different sizes can be used for matching, and the movable assembly 200 is suitable for the movable assemblies 200 with different first positions and second positions or different sizes of the water passing cavities 201. The adaptor 220 may be integrally formed with the movable base 230 to form a single piece. As shown in fig. 1 and 3, the bracket 500 is further included.

The second elastic member 510 has a second elastic force on the adaptor 220. The second elastic force urges the end surface of the movable assembly 200 where the water passing chamber 201 is located toward the water passing assembly 300. In this embodiment, the water passing cavity 201 is disposed on the bottom surface of the movable assembly 200, the bottom surface of the movable assembly 200 is tightly attached to the water passing assembly 300, and the second elastic force presses the movable assembly 200 downward, so as to increase the pressure between the movable assembly 200 and the water passing assembly 300, and further increase the friction between the two components, so that the movable assembly 200 is kept at the second position before the temperature sensing element 400 is reset.

In some embodiments, as shown in fig. 1 and 7, a post 221 is provided on the adaptor 220. The column 221 is hollow and has an upper end opened. The second elastic member 510 is installed in the column 221. The second elastic member 510 includes a second spring 511 and a top post 512. Both ends of the second spring 511 are respectively abutted against the top post 512 and the upright post 221. The upper end of the top column 512 is directed toward the bracket 500, and the upper end of the top column 512 is provided as a spherical end 513. The spherical end 513 abuts against the bottom surface of the bracket 500.
