[0018] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0019] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figures 1 to 5As shown, the present embodiment provides a shower cooling mechanism with adjustable drainage (hereinafter referred to as cooling mechanism), the cooling mechanism comprises a valve body 1 having at least one water outlet 12, the valve body 1 having at least one drainage channel 11 connected to the water outlet end of the shower thermostatic valve, the water outlet 12 connected to the drainage channel 11, the drainage channel 11 is provided with a valve cavity 13 opening outward, the valve cavity 13 is provided with a valve core 2 for adjusting the drainage volume of the drainage channel 11, the valve core 2 comprises an outer valve core 211 and an inner valve core 212 movably assembled in the outer valve core 211, the side wall of the outer valve core 211 has a water through hole 2111 connected to the drainage channel 11, the inner valve core 212 is moved so that the outer wall of the inner valve core 212 partially blocks the water through hole 2111, so as to adjust the water through area of ​​the water through hole 2111, thereby adjusting the drainage volume of the drainage channel 11.

[0021] In this embodiment, Figure 1 As shown, a notch is provided on the outer wall of the valve body 1 and is connected to the drainage channel 11 to form an installation cavity. The outer valve core 211 is fixed in the installation cavity of the valve body 1 and forms a sealing fit with the inner wall of the installation cavity. The inner valve core 212 is movably arranged in the outer valve core 211 and forms a sealing fit. At this time, the installation cavity is the valve cavity 13. In addition, a shower head, such as a handheld shower head, is installed at the water outlet 12.

[0022] like Figure 2 The inner wall of the outer valve core 211 shown has an inner thread, the outer wall of the inner valve core 212 has an outer thread, and the inner valve core 212 is rotatably assembled in the outer valve core 211 through a threaded connection, so that the inner valve core 212 can move axially in the outer valve core 211.

[0023] The outer wall of the outer valve core 211 has an outer thread, and the inner wall of the valve cavity 13 has an inner thread. The outer valve core 211 is assembled in the valve cavity 13 through threaded connection to fix the outer valve core 211 on the inner wall of the valve cavity 13.

[0024] When it is necessary to adjust the water output of the water outlet 12, rotate the inner valve core 212 to make the inner valve core 212 rotate in or out of the outer valve core 211, so as to drive the inner valve core 212 to move along the axial direction of the inner cavity of the outer valve core 211, so as to adjust the relative position between the outer wall part 2123 of the inner valve core 212 and the water hole 2111 of the outer valve core 211, thereby adjusting the water flow area of ​​the outer wall part 2123 of the inner valve core 212 to the water hole 2111 of the outer valve core 211, so as to meet the regulation of the drainage volume in the drainage channel 11.

[0025] By moving the inner valve core 212 to adjust the water flow area of ​​the water hole 2111 of the outer valve core 211, the drainage volume in the drainage channel 11 can be adjusted to prevent the water sprayed from the shower head connected to the water outlet 12 from spraying outside the shower room when the water pressure is high, thereby improving the user experience.

[0026] In another preferred embodiment, Figure 1 As shown, the valve chamber 13 is also equipped with a valve for preventing water from flowing back. Figure 4 The one-way valve 221 shown is connected to the water hole 2111 , and the end of the outer valve core 211 abuts against the one-way valve 221 .

[0027] In a specific implementation, the thread between the outer valve core 211 and the drainage channel 11 is a left-hand thread, and the thread between the inner valve core 212 and the outer valve core 211 is a right-hand thread, so as to ensure that the outer valve core 211 will not be rotated while the inner valve core 212 is rotated.

[0028] Further preferably, a valve is provided between the outer valve core 211 and the one-way valve 221. Figure 5 The annular sealing gasket 222 is shown, and the end of the outer valve core 211 abuts against the sealing gasket 222 , and the inner valve core 212 is rotated and moved until the end of the inner valve core 212 abuts against the sealing gasket 222 to block the one-way valve 221 .

[0029] The drainage channel 11 , the water hole 2111 of the outer valve core 211 , the through hole of the sealing gasket 222 and the one-way water outlet channel of the one-way valve 221 together form a water flow channel connected to the water outlet 12 .

[0030] The outer valve core 211 has an installation channel 2112 that runs through its upper and lower surfaces. The inner valve core 212 can be movably assembled in the installation channel 2112. The wall of the installation channel 2112 close to the one-way valve 221 is provided with a water hole 2111 to ensure that water flowing out from the water outlet end of the thermostatic valve of the shower can only flow in from the water hole 2111 of the outer valve core 211, and then flow through the through hole of the sealing gasket 222 and the one-way water outlet channel of the one-way valve 221, and then flow from the water outlet 12 to the shower head.

[0031] Of course, in other embodiments, the thread between the outer valve core 211 and the drainage channel 11 may also be a right-hand thread, and the thread between the inner valve core 212 and the outer valve core 211 may be a left-hand thread.

[0032] Further preferably, Figure 3 The inner valve core 212 shown has a nut portion 2121 and a water retaining portion 2122 connected to each other. The nut portion 2121 is movably screwed to the inner wall of the installation channel 2112, and the water retaining portion 2122 extends into the installation channel 2112, so that the water retaining portion 2122 can partially cover the water hole 2111 of the outer valve core 211.

[0033] In this specific embodiment, the side of the outer valve core 211 facing away from the one-way valve 221 protrudes from the outer wall of the valve body 1 .

[0034] The nut portion 2121 is located on the outward side of the installation channel 2112, and the water retaining portion 2122 is located on the inward side of the installation channel 2112. Since the inner and outer sides of the outer valve core 211 have openings, the outer opening of the outer valve core 211 is convenient for the user to directly rotate the nut portion 2121 of the inner valve core 212 through a tool to drive the water retaining portion 2122 to be tightened or unscrewed, so as to adjust the relative position between the outer peripheral surface of the water retaining portion 2122 and the water passing hole 2111 of the outer valve core 211, so as to adjust the water passing area, and further realize effective adjustment of the drainage volume in the drainage channel 11, so that the user can adjust the corresponding cooling and drainage volume according to the external water pressure used, so as to avoid excessive water spray from the shower connected to the water outlet 12.

[0035] When the end of the water retaining portion 2122 facing the one-way valve 221 abuts against the sealing gasket 222 , the water retaining portion 2122 completely blocks the through hole of the sealing gasket 222 and also blocks the water flow of the one-way valve 221 , thereby blocking the water in the drainage channel 11 from flowing toward the water outlet 12 .

[0036] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
