Technical Field

[0001] The utility model relates to the field of shower devices, in particular to a shower device with mechanical drainage. Background Art

[0002] The mixing valve of the shower device is connected to shower accessories such as handheld showers and overhead showers through pipes. After use, a large amount of residual water is likely to remain in the pipes. After the residual water in the pipes cools down, the user will need to constantly adjust the water temperature before taking a shower the next time. Otherwise, the user may be easily stimulated by cold water and suffer from health problems, which results in a poor user experience.

[0003] Currently, there is a method of controlling the shower device to pre-drain the cold water in the pipeline through touch screen operation or remote control operation in conjunction with a solenoid valve. However, elderly users are not familiar with electronic control operations such as touch screens or remote controls. Therefore, the existing shower devices with pre-drain cold water function are too complicated and are not suitable for elderly users.

[0004] In view of the above problems in the prior art, the purpose of the present invention is to design a mechanical drainage shower device that is convenient for elderly users to use. Utility Model Content

[0006] The technical solution of the utility model is:

[0007] A mechanical drainage shower device, comprising:

[0008] A water mixing device, comprising a water inlet end connected to a cold water pipeline and a hot water pipeline, and a water outlet end connected to a main pipeline, wherein the main pipeline comprises a drainage branch and a plurality of water outlet branches;

The drainage outlet is provided on one side of the drainage cylinder, and the end of the drainage cylinder away from the drainage outlet is provided as a water inlet end with a water outlet hole penetrating through the side wall. The second water inlet, the inside of the drainage cylinder, and the drainage outlet are connected in sequence to form the drainage channel, and the second water inlet, the outside of the drainage cylinder, the water outlet hole, and the drainage outlet are connected in sequence to form the water outlet channel. The drainage valve is used to control the opening and closing of the water inlet end of the drainage cylinder, and the water outlet valve is used to control the opening and closing of the water outlet hole.

[0012] Furthermore, the water outlet valve includes a water outlet blocking member which is slidably arranged in the pre-drainage device and whose inner end is blocked in the water outlet hole, a driving member whose middle part is rotatably connected to the pre-drainage device and one end is rotatably connected to the outer end of the water outlet blocking member, and the other end of the driving member is connected to the water outlet button; when the water outlet button is pressed internally, the other end of the driving member swings inward and one end swings outward to drive the inner end of the water outlet blocking member to disengage from the water outlet hole to open the water outlet channel.

[0013] Furthermore, an inner cylinder and an outer cylinder distributed inside and outside are provided on one side of the pre-drainage device close to the drainage branch, one end of the outer cylinder is connected to the drainage branch to form the second water inlet, and the inner cylinder is penetrated by a first water inlet connected to the second water inlet, and the drainage valve includes a drainage sealing part slidably arranged in the drainage channel, and a temperature memory spring is sleeved on the outside of the drainage sealing part and used to drive the drainage sealing part to block or detach from the water inlet end of the drainage cylinder, and the two ends of the drainage sealing part are respectively limited and slidable in the inner cylinder and the drainage cylinder; when the temperature is low, the temperature memory spring retracts to drive the drainage sealing part to detach from the water inlet end of the drainage cylinder to open the drainage channel for drainage, and when the temperature is heated, the temperature memory spring retracts to drive the drainage sealing part to block the water inlet end of the drainage cylinder to close the drainage channel to stop drainage.

[0014] Furthermore, a plurality of shower openings respectively connected to a plurality of the water outlet branches and the drain openings are formed through the bottom side of the shell, and the shower openings include a long hole shape or a round hole shape.

[0015] Furthermore, the water mixing device is a water mixing valve arranged on one side of the interior of the shell, a temperature adjustment knob connected to the water mixing valve is penetrated through the right side wall of the shell, the water inlet and the water outlet are arranged horizontally and distributed front to back on the left side of the water mixing valve, the cold water pipeline and the hot water pipeline are arranged side by side on the rear side of the water inlet, the main pipeline and the water outlet are arranged side by side, a drainage branch and several water outlet branches are arranged side by side from right to left on the front side of the main pipeline, and several shower outlets are arranged on the left side, middle side and right side of the bottom of the shell.

[0016] Therefore, the utility model provides the following effects and / or advantages:

[0017] 1. The present application adds a pre-drain device so that when the user uses the shower device again after the residual water in the pipe has cooled down to cold water, the user can open the drainage branch through the pre-drain switch so that the residual water in the pipe is drained through the drainage branch, the drainage channel, the drainage outlet and the shower connected to the drainage outlet in sequence, and then close the drainage valve. After the shower stops discharging water, the user is reminded to drain the cold water. The user then opens the corresponding water outlet branch or drainage outlet through the shower switch or water outlet button so that the corresponding shower can discharge water and then take a shower. Therefore, pre-draining of cold water can be achieved through a one-touch mechanical operation of the pre-drain switch and an intuitive reminder can be given by stopping the water discharge after the cold water is drained. It can also be easily operated for elderly users, thereby improving the adaptability of the shower device. At the same time, by connecting the drain outlet to the corresponding shower head, after pre-draining the residual water through the drain outlet, pressing the water discharge button can also control the water discharge of the shower head connected to the drain outlet for showering with one touch. This not only avoids the setting of the drain outlet resulting in a reduction in the ports that can be connected to the shower head and affects the functional richness of the shower device, but also can discharge the cold water in the pipe of the shower head (such as a shower head, etc.) connected to the drain outlet, further improving the user experience.

[0018] 2. In the present application, the second water inlet, the inner side of the drain cylinder, and the drain outlet are connected in sequence to form a drainage channel. The second water inlet, the outer side of the drain cylinder, the water outlet, and the drain outlet are connected in sequence to form a water outlet channel. The drainage valve is used to control the opening and closing of the water inlet end of the drain cylinder, and the water outlet valve is used to control the opening and closing of the water outlet. Thus, by merging the water inlet end of the drainage channel and the water outlet channel, the structural compactness of the pre-drainage device 5 is improved and its volume share is reduced. At the same time, the water inlet end of the drain cylinder and the water outlet are vertically distributed to avoid mutual interference between the drainage valve and the water outlet valve, so that the drainage channel and the water outlet channel can be opened and closed independently, so as to realize the dual functions of cold water discharge through the drainage channel and warm water discharge through the water outlet channel, thereby improving the functionality of the pre-drainage device and ensuring the functional diversity of the shower device.

[0019] 3. The present application drives the driving member to swing by the water outlet button to achieve the sealing or disengagement of the water outlet valve from the water outlet hole, so as to close or open the water outlet channel. After the drain valve closes the drain channel to stop the drain outlet from discharging, the water outlet channel is opened by simple mechanical operation of the water outlet button to discharge warm water into the shower connected to the drain outlet. The pre-drainage device can realize both pre-draining of cold water and discharge of warm water to the shower connected to the drain outlet for showering, thereby improving the functional diversity of the pre-drainage device. Such an arrangement ensures that the added drainage channel does not monopolize the water outlet branch of the shower device, so that the functional diversity of the shower device is not reduced.

[0020] 4. In this application, when the water introduced into the second water inlet is cold water, the temperature memory spring retracts to drive the drainage plugging part to separate from the inner cylinder to open the drainage channel for drainage. When the water temperature introduced into the second water inlet rises to the set temperature, the temperature memory spring retracts to drive the drainage plugging part to block the water inlet end of the drainage cylinder to close the drainage channel to stop drainage. Thus, cold water is discharged through the drainage channel until the water temperature reaches the set temperature and then the drainage is stopped to avoid the situation where too much warm water is discharged and causes water resources to be wasted. At the same time, stopping the drainage can intuitively remind the user that the water flow in the shower device has reached the preset temperature and the user can directly take a shower.

[0021] It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:

[0028] refer to Figure 1-5 , a mechanical drainage shower device, comprising:

[0029] The water mixing device 1 comprises a water inlet 11 connected to a cold water pipeline 2 and a hot water pipeline 3, and a water outlet 12 connected to a main pipeline 4, wherein the main pipeline 4 comprises a drainage branch 41 and a plurality of water outlet branches 42;

[0030] The pre-drainage device 5 comprises a drainage valve 51, a water outlet valve 52, a drainage port 53, and a drainage channel and a water outlet channel respectively connected to the drainage branch 41 and the drainage port 53, wherein the drainage valve 51 is used to control the opening and closing of the drainage channel, and the water outlet valve 52 is used to control the opening and closing of the water outlet channel;

[0031] The shell body 6, the water mixing device 1 and the pre-drainage device 5 are all arranged in the shell body 6, and the shell body 6 is provided with a water outlet button 61 for controlling the water outlet valve 52, a pre-drainage switch 62 and a plurality of shower switches 63 for controlling the opening and closing of one drainage branch 41 and a plurality of drainage branches 42 respectively, and a plurality of drainage branches 42 and drainage outlets 53 are respectively connected to corresponding showers, and the showers can be shower heads, nozzles, overhead showers, etc. In this embodiment, the shower connected to the drainage outlet 53 is a shower head. In other embodiments, the shower connected to the drainage outlet 53 can also be other existing showers, which are not specifically limited here.

[0032] The arrangement of the above structure, through the addition of the pre-drain device 5, allows the user to use the shower device again after the residual water in the pipe has cooled down to cold water, by opening the drainage branch 41 through the pre-drain switch 62, so that the residual water in the pipe is drained through the drainage branch 41, the drainage channel, the drainage outlet 53 and the shower connected to the drainage outlet 53 in sequence, and then close the drainage valve 51. After the shower stops discharging water, the user is reminded to drain the cold water. The user then opens the corresponding water outlet branch 42 or drainage outlet 53 through the shower switch 63 or the water outlet button 61 to make the corresponding shower discharge water and then take a bath. Therefore, the pre-draining of cold water can be mechanically operated by one button through the pre-drain switch 62, and an intuitive reminder can be given by stopping the water discharge after the cold water is drained. It can also be easily operated for elderly users, thereby improving the adaptability of the shower device. At the same time, by connecting the drain outlet 53 to the corresponding shower, after pre-draining the residual water through the drain outlet 53, pressing the water discharge button 61 can also control the water discharge of the shower connected to the drain outlet 53 by one button for showering. This can not only avoid the setting of the drain outlet 53 resulting in a reduction in the ports that can be connected to the shower, and avoid affecting the functional richness of the shower device, but also can discharge the cold water in the shower pipe connected to the drain outlet 53, thereby further improving the user experience.

[0033] In order to reduce the volume of the pre-drainage device 5 while realizing the corresponding functions of the pre-drainage device 5, a second water inlet 551 connected to the drainage branch 41 is provided on one side of the pre-drainage device 5, and a drainage cylinder 56 is provided on the other side of the pre-drainage device 5. The drainage outlet 53 is provided on one side of the drainage cylinder 56, and the end of the drainage cylinder 56 away from the drainage outlet 53 is provided as a water inlet end with a water outlet hole 561 penetrating through the side wall. The second water inlet 551, the inner side of the drainage cylinder 56, and the drainage outlet 53 are connected in sequence to form the drainage channel. The second water inlet 551, the outer side of the drainage cylinder 56, the water outlet hole 561, and the drainage outlet 53 are connected in sequence to form the water outlet channel. The drainage valve 51 is used to control the opening and closing of the water inlet end of the drainage cylinder 56, and the water outlet valve 52 is used to control the opening and closing of the water outlet hole 561. Thus, the structural compactness of the pre-drainage device 5 is improved by merging the water inlet ends of the drainage channel and the water outlet channel, and its volume share is reduced. At the same time, the water inlet end of the drainage cylinder 56 and the water outlet hole 561 are vertically distributed to avoid mutual interference between the drainage valve 51 and the water outlet valve 52, so that the drainage channel and the water outlet channel can be opened and closed independently to realize the dual functions of cold water discharge through the drainage channel and warm water discharge through the water outlet channel, thereby improving the functionality of the pre-drainage device 5 and ensuring the functional diversity of the shower device.

[0034] In order to mechanically control the water outlet button 61 to open the water outlet channel after the drain valve 51 closes the drain channel to stop draining from the drain outlet 53, so that the drain outlet 53 discharges warm water into the shower connected to the drain outlet 53, the water outlet valve 52 includes a water outlet blocking member 521 which is slidably arranged in the pre-drainage device 5 and whose inner end is blocked in the water outlet hole 561, a driving member 522 which is rotatably connected to the pre-drainage device 5 in the middle and one end is rotatably connected to the outer end of the water outlet blocking member 521, and the other end of the driving member 522 is connected to the water outlet button 61; when the water outlet button 61 is pressed internally, the other end of the driving member 522 swings inward and one end swings outward to drive the inner end of the water outlet blocking member 521 to disengage from the water outlet hole 561 to open the water outlet channel. Thereby, the driving member 522 is driven to swing by the water outlet button 61 to realize the water outlet valve 52 to block or disengage from the water outlet hole 561 to close or open the water outlet channel, so that after the drain valve 51 closes the drain channel to stop the drain port 53 from discharging, the water outlet channel is opened by a simple mechanical operation of the water outlet button 61 to enable the drain port 53 to discharge warm water into the shower connected to the drain port 53, so that the pre-drainage device 5 can realize both pre-draining of cold water and discharging warm water to the shower connected to the drain port 53 for showering, thereby improving the functional diversity of the pre-drainage device 5. Such an arrangement ensures that the added drain channel does not monopolize the water outlet branch of the shower device, so that the functional diversity of the shower device is not reduced.

[0035] In order to avoid wasting water resources due to excessive discharge of water flow, the pre-drainage device 5 is provided with an inner cylinder 54 and an outer cylinder 55 distributed inside and outside on one side close to the drainage branch 41. One end of the outer cylinder 55 is connected to the drainage branch 41 to form the second water inlet 551. The inner cylinder 54 is penetrated by a first water inlet 541 connected to the second water inlet 551. The drainage valve 51 includes a drainage plugging member 511 slidably arranged in the drainage channel, a drainage plugging member 511 sleeved on the outside of the drainage plugging member 511 and used to drive the drainage plugging member 511 to block or detach from the drainage cylinder 56 to enter the water. The temperature memory spring 512 at the end, the two ends of the drainage plugging member 511 are respectively limited and slidably arranged in the inner tube 54 and the drainage tube 56; when the water introduced into the second water inlet is cold water, the temperature memory spring 512 shrinks at low temperature to drive the drainage plugging member 511 to separate from the water inlet end of the drainage tube 56, so as to open the drainage channel for drainage, and when the water temperature introduced into the second water inlet rises to the set temperature, the temperature memory spring 512 shrinks when heated to drive the drainage plugging member 511 to block the water inlet end of the drainage tube 56, so as to close the drainage channel and stop drainage. Thus, the cold water is discharged through the drainage channel until the water temperature reaches the set temperature, and then the drainage is stopped, so as to avoid the situation where too much warm water is discharged and flows out, resulting in a waste of water resources. At the same time, by stopping the drainage, the user can be intuitively reminded that the water flow in the shower device has reached the preset temperature, and can directly take a shower.

[0036] In order to improve the water outlet diversity of the shower device, a plurality of shower outlets 64 are provided through the bottom side of the shell 6 and respectively connect the plurality of water outlet branches 42 and the drain ports 53 . The shower outlets 64 include elongated holes or circular holes.

[0037] In order to achieve mechanical operation temperature adjustment, the water mixing device 1 is a water mixing valve arranged on one side of the housing 6. The right side wall of the housing 6 is penetrated with a temperature adjustment knob 65 connected to the water mixing valve. The water inlet 11 and the water outlet 12 are arranged horizontally and distributed front and back on the left side of the water mixing valve. The cold water pipeline 2 and the hot water pipeline 3 are arranged side by side on the rear side of the water inlet 11. The main pipeline 4 and the water outlet 12 are arranged side by side. A drainage branch 41 and a plurality of water outlet branches 42 are arranged side by side from right to left on the front side of the main pipeline 4. A plurality of shower ports 64 are arranged on the left side, the middle side and the right side of the bottom of the housing 6. Thus, mechanical operation temperature adjustment is achieved through the temperature adjustment knob 65, so that elderly users can also adjust the temperature of the shower device easily. At the same time, through the position distribution of the above structure, the internal structure of the shower device is compact, its volume ratio is reduced, and its installation adaptability is improved.

[0038] Working principle:

[0039] The temperature is adjusted to the desired set temperature by the temperature adjustment knob 65, and the pre-drain switch 62 is pressed. At this time, the temperature memory spring 512 is in a state of low temperature retraction to drive the drainage plugging member 511 to separate from the inner tube 54, and the drainage channel is in an open state. Therefore, the cold water remaining in the pipeline is discharged through the drainage branch 41, the drainage channel, the drainage outlet 53, and the shower (such as a shower head, etc.) connected to the drainage outlet 53 in sequence. Until the temperature of the water flowing through the drainage channel rises to the set temperature, the temperature memory spring 512 is heated up. The retraction drives the drainage sealing member 511 to block the water inlet end of the drainage cylinder 56 to close the drainage channel and stop drainage, intuitively reminding the user that drainage is completed and the water temperature in the shower device has reached the set temperature. The user can press any of the shower switches 63 to turn on the corresponding shower for showering, or press the water outlet button 61 to make the other end of the driving member 522 swing inward and one end swing outward to drive the inner end of the water outlet sealing member 521 to disengage from the water outlet hole 561 to open the water outlet channel, so that the shower connected to the drainage port 53 can discharge water for showering.

[0040] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
