[0037] The technical solution of the present invention is further described below through the accompanying drawings and specific embodiments.

[0038] Example 1

[0039] refer to Figure 1-Figure 6 The present embodiment provides a sliding thermostatic mechanical shower, comprising: a cold water inlet 1, a hot water inlet 2, a switching valve 3 and a dial button 4; the switching valve 3 has a water inlet 31; the dial button 4 is arranged on the surface of the shower and can be moved along the length direction of the shower;

[0040] When the dial button 4 is turned, the dial button 4 drives the water inlet 34 to connect only to the cold water inlet 1, or to connect both the cold water inlet 1 and the hot water inlet 2, or to connect only to the hot water inlet 2.

[0041] The above sliding thermostatic shower head drives the water inlet 34 of the valve body to connect with one or both of the cold water inlet 1 and the hot water inlet 2 through a dial button 4, thereby changing the temperature of the water outlet. This thermostatic method can achieve the purpose of increasing or decreasing the temperature by sliding the dial button 4 in one direction, which is very intuitive, and the cost of the purely mechanical thermostatic method is relatively low. In addition, the dial button 4 is arranged on the surface of the shower head, which is also very convenient for the user to operate the dial button 4.

[0042] In this embodiment, in order to achieve the temperature adjustment operation, the switching valve 3 includes a valve body 31 and a switching shaft 32 connected to the valve body 31; one end of the switching shaft 32 is connected to the dial button 4 through a connecting piece 33. In this embodiment, the connecting piece 33 is a swing shaft, one end of which is connected to the dial button 4, and the other end is connected to one end of the switching shaft 32. In this way, when the dial button 4 is translated, the switching shaft 32 will swing around the fulcrum connected to the switching shaft 32, and the push-pull force generated by the swing will push or pull the switching shaft 32. When the switching shaft 32 moves, it will drive the valve body 31 to move. When the valve body 31 moves, the water inlet 34 will only connect to the cold water inlet 1, or connect to the cold water inlet 1 and the hot water inlet 2 at the same time, or only connect to the hot water inlet 2.

[0043] In this embodiment, the side wall of the valve body 31 is provided with the water inlet 34. Specifically, when the dial button 4 is located in the middle position, the water inlet 34 is connected to the cold water inlet 1 and the hot water inlet 2 at the same time; when the dial button 4 moves to the two end positions, the water inlet 34 is only connected to the cold water inlet 1 or the hot water inlet 2. In this way, when the dial button 4 is located in the middle position, the cold water inlet 1 and the hot water inlet 2 are connected to the water inlet 34 respectively, and the water outflow is a mixture of cold water and hot water. When the dial button 4 moves to the left relative to the middle position, the water flow area between the water inlet 34 and the hot water inlet 2 becomes larger, and the water flow area between the water inlet 34 and the cold water inlet 1 becomes smaller. When the dial button 4 moves to the right relative to the middle position, the water flow area between the water inlet 34 and the cold water inlet 1 becomes larger, and the water flow area between the water inlet 34 and the hot water inlet 2 becomes smaller. In this way, the effect of stepless water temperature regulation is achieved.

[0044] Example 2

[0045] refer to Figure 7 The difference between this embodiment and embodiment 1 is that the switching valve 3 includes a cold water proportional valve 35 and a hot water proportional valve 36, and the water inlet 34 is connected to the water outlets of the cold water proportional valve 35 and the hot water proportional valve 36. By adjusting the water flow area of ​​the water outlets of the cold water proportional valve 35 and the hot water proportional valve 36, the purpose of water temperature regulation can also be achieved.

[0046] In order to achieve the goal that the water outlet flow area of ​​the cold water proportional valve 35 and the hot water proportional valve 36 changes when the knob 4 is turned, the cold water proportional valve 35 and the hot water proportional valve 36 respectively include a plunger 37 for opening or closing the water outlet; the plungers 37 of the cold water proportional valve 35 and the hot water proportional valve 36 are connected by an adjusting rod 38.

[0047] In this example, the middle part of the adjusting rod 38 is the swing fulcrum; when the adjusting rod 38 is in a horizontal position, the plunger 37 opens the water outlets of the cold water proportional valve 35 and the hot water proportional valve 36 respectively; when one end of the adjusting rod 38 swings toward the direction close to the cold water proportional valve 35 or the hot water proportional valve 36, the adjusting rod 38 pushes the plunger 37 to gradually close the water outlet of the cold water proportional valve 35 or the hot water proportional valve 36.

[0048] In order to achieve the swinging of the adjusting rod 38 by the dial button 4, when the dial button 4 is translated to the left or right relative to the fulcrum, the thrust generated between the dial button 4 and the adjusting rod 38 pushes the adjusting rod 38 to swing toward the direction close to the cold water proportional valve 35 or the hot water proportional valve 36. Specifically, the adjusting rod 38 extends from the fulcrum to both sides on the side facing the dial button 4 to form an inclined surface.

[0049] Example 3

[0050] refer to Figure 8 The difference between this embodiment and embodiment 1 is that the switching valve 3 includes a cold water proportional valve 35 and a hot water proportional valve 36, and the water inlet 34 is connected to the water outlets of the cold water proportional valve 35 and the hot water proportional valve 36. By adjusting the water flow area of ​​the water outlets of the cold water proportional valve 35 and the hot water proportional valve 36, the purpose of water temperature regulation can also be achieved.

[0051] In order to achieve the goal that the water outlet flow area of ​​the cold water proportional valve 35 and the hot water proportional valve 36 changes when the knob 4 is turned, the cold water proportional valve 35 and the hot water proportional valve 36 respectively include a plunger 37 for opening or closing the water outlet; the plungers 37 of the cold water proportional valve 35 and the hot water proportional valve 36 are connected by an adjusting rod 38.

[0052] In this example, in order to achieve the goal of the adjusting rod 38 driving the plunger 37 to change the water outlet water flow area of ​​the cold water proportional valve 35 and the hot water proportional valve 36, the adjusting rod 38 is linked to the dial button 4 along the direction of movement of the dial button 4; when the dial button 4 is translated to the left or right relative to the middle position, the thrust generated by the adjusting rod 38 and the plunger 37 pushes the plunger 37 to close the water outlet of the cold water proportional valve 35 or the hot water proportional valve 36.

[0053] Example 4

[0054] refer to Figure 9-12This embodiment also provides a display module used in the sliding temperature control mechanical shower in Embodiments 1 to 3, including: a light-emitting module 51, a lamp holder 52 and a panel 53; the light-emitting module 51 and the panel 53 are respectively placed on both sides of the lamp holder 52 along the thickness direction of the lamp holder; the side of the lamp holder 52 facing the light-emitting module 51 is divided into a plurality of cells 521 along the sliding temperature control direction, and the surface of the cell 521 along the thickness direction of the lamp holder 52 is a light-transmitting surface, and the light-emitting module 51 is provided with light-emitting units 511 corresponding to the cells 521 one by one;

[0055] The panel 53 is a transparent panel, and a side thereof facing the lamp holder 52 is covered with a light-transmitting layer. On a side of the light-transmitting layer facing the lamp holder 20 , opaque numbers 531 corresponding to some cells are arranged one by one.

[0056] Through the above design, when the user uses the dial 4 to adjust the temperature, the temperature sensing element can sense the temperature change of the outlet water temperature and send the detection value to the main control chip. The main control chip lights up the corresponding light-emitting unit 511 according to the temperature. The light emitted by the light-emitting unit 511 is blocked by the ribs around the cell 521 and emitted from the light-transmitting surface of the cell 521. The emitted light is then irradiated onto the panel 53 through the light-transmitting layer, thus forming an illuminated area on the panel 53 with the same shape as the cell 521. For example, if the cell 521 is rectangular, a rectangular area on the panel 53 is illuminated. The number 531 is opaque, so a black or gray number will be displayed on this rectangular area. The user can know the current outlet water temperature.

[0057] In this embodiment, the light-transmitting layer is a white coating printed on the panel 53, and the number 531 is further printed on the light-transmitting coating. In this way, when there is no light irradiating the panel 53 from behind, the panel 53 is pure white when viewed from the front, and the integrity is relatively good.

[0058] In this embodiment, there are N cells 521, of which N-1 corresponds to the opaque number 531 one by one; when the outlet water temperature is greater than the maximum value of the opaque number, the light-emitting unit 511 corresponding to the remaining cell 521 flashes. The purpose of this design is to remind consumers to lower the water temperature through the flashing of the cell 521 when the outlet water temperature is too high, so as to avoid the high temperature causing harm to the consumer's body.

[0059] In addition, in order to further facilitate the user to adjust the temperature and switch the water outlet terminal, the panel 53 is provided with a water outlet terminal indication icon 532 and a heating and cooling indication icon 533 on the side facing away from the light-transmitting layer. The heating and cooling indication icons 533 are red and blue respectively, and the dial button 4 is located at the junction of the blue and red parts. Turning to the blue part means cooling, and vice versa, it is clear and concise. The water outlet terminal indication icon 532 includes three gear icons of hand-held shower, overhead shower and water off. The icons correspond to the three icon positions of hand-held shower, overhead shower and water off one by one. As long as the dial button is turned to the corresponding icon, the corresponding water outlet terminal can be switched. Since the water outlet terminal indicator icon 532 and the temperature increase and temperature decrease indicator icon 533 are arranged on the side of the panel 53 facing the light-transmitting layer, even when there is no light shining on the panel 53 from behind, the water outlet terminal indicator icon 532 and the temperature increase and temperature decrease indicator icon 533 can also be seen from the front of the panel, so that the user can observe the water outlet terminal indicator icon 532 and the temperature increase and temperature decrease indicator icon 533 before starting to shower.

[0060] The above-mentioned display module, in addition to being applied to the sliding thermostatic mechanical showers of embodiments 1-3, can also be widely applied to other sliding thermostatic showers, and is not limited thereto, and will not be described in detail here.

[0061] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
